32 | How to Export Flash Animation Data I'd love for my partner, the artist, to be able to animate using flash movieclips and timelines. Then I, the programmer, would like to read the raw Flash info and re program it into my engine of choice (which happens to be Torque2D). The data I'd want is the bitmap images that were used in Flash, like the head and body the links between the images, like where the head connects to the body the motion data from the flash animation, like move, rotate (at what speed), shear, etc. for the head or arms or whatever. Is there any way to get this data? Here's what I know so far. There are tools like SWFSheet and Spriteloq that convert the entire flash animation into a frame by frame sprite animation (in a sprite sheet). This would take too much space in my case, so I'd like to avoid that. Re animating on the fly would take much less texture memory. There is a PDF that describes the SWF file format but NOT the individual components like the movieclips. So anyone know of a library I can use, or how I can learn more about the movieclip components and whatnot? (more better tags transform, export, convert) |
32 | Changing colour while keeping gradient I'm making a Flash game with ActionScript 3 and I have a square with a gradient applied to it. I am trying to programmatically changing the colour of the square depending on time, for example, some times it is orange, some times it is red, but it must always fade to black at the bottom. The problem is, I'm using ColorTransform (as per here) but it seems to overwrite the gradient and simply fill the square with the solid colour. This isn't what I want. I want the colour that is chosen to fade to black at the bottom, like the original gradient. How can I do this? Is there a way to only change the "hue" of the symbol (IE not filling the entire thing with a solid colour), or will I have to reapply a gradient programmatically, with the desired colours? |
32 | Handle Multiple Scene For my game, now I adopt the strategy to create multiple scene. For this I have to ask two question please provide your view for my and other members for improvement. I have created single TextureManager class in which I load all the graphics of the game which is at least 50 MB. My first question is that this much loading of texture will create any problem in game performance,So all the scene in the game have reference to this TextureManager class and they access corresponding texture region using dot operator. if other better strategy for this texture loading then please suggest me. My second question is that my actual game scene uses bound camera and I perform scrolling on that camera but my other scene uses the normal camera. So in this situation what to do? how to use multiple camera for single engine? or how to reset available current camera? My current working platform is andengine. Thank for you support. |
32 | Is there a fundamental technical reason for Flash being a more popular game platform than JavaScript? Both Javascript and AS3 are implementations of ECMAScript. Is there a fundamental technical reason for Flash being so much more prevalent as a game publishing platform, when compared to Javascript? |
32 | Level Design Char Traveling to and from a Site I'm developing a 2d platformer game where your character can travel to and from sites as he pleases. To travel to and from these sites the character must travel along a path between his current location and his destination (see illustration below). And of course the idea is that you can travel through the level backwards if you wish to return to Site One. But as you probably realize, doing this may provoke some serious problems, and will put limitations on the level design (no cliffs or long drops because then your character wouldn't be able to overcome them on the way back). I've come up with multiple ways to overcome this (such as designing two levels for the same path etc), but I was wondering if anyone else has any creative work arounds for this problem. Any help and advice is appreciated. |
32 | Need help starting with a game in Flash AS3 I am kinda new to flash AS3. I have written some stuff and now I now the basics of AS. I want to develop a game in which my character moves. exactly like the way Super Mario moves(the background changes and new obstacles come in the way like and animation with which you can interact by climbing and shooting etc.) There is one big thing that I don't understand is that how to make my background moving and introduce new obstacles when my character moves forward. Currently my scene is static which means the background is the same and obstacles are also stationary. Can some point me to a tutorial or give me an answer that solves my confusion? thanks |
32 | Rotate spritesheet graphics in flixel I am using the flash flixel engine, and have a sprite sheet of a spaceship from top down view. The sprite sheet includes a bunch of different states and animation frames. Problem is that I have drawn them all facing upwards (north), and my maths is all done assuming the sprites face to the right (east). In flixel v2.5 is there a way to rotate the sprite graphics without affecting the "angle" property of the FlxSprite that is using the graphics? I was thinking along the lines of a pre process, as I initialise everything. I don't really want to fix all the graphics, or hack into my maths at this point. This also might come in handy later. |
32 | What is the standard way of delivering HTML5 games to portals and such? Let me explain what I mean by "standard way of delivering"... Think about Flash games sites. Flash games can be delivered as a single file, either hosted by the site, or, I guess, provided by someone else. HTML5 games, on the other hand, don't have something so standard. Usually, they have their own page, and portals just link to that page. I think that it greatly hinders the purpose of that portal, because, well, you want people to stay on your site and look for other games. Now, I think that a some kind of iframe way of delivering games would help solve this problem greatly. I saw some games doing that, and they were often included on tutorial sites to show a live example, which is obviously a great thing. So, is there a standard at all? Any suggestions? Can you create a game that just preloads itself in an iframe (I heard something about a "single document" or something)? |
32 | How can I develop Flash games without expensive software? I've been playing with writing flash games in my spare time, but up to this point, I've just been using a trial version of Adobe Flash Professional. I'm aware of FlashDevelop, but their documentation is basically non existent when it comes to the workflow of developing purely with FlashDevelop. Does anyone know of any good tutorials for developing Flash games purely with FlashDevelop? Alternatively, does anyone have any other free cheap software recommendations to use in place of Flash Professional? |
32 | What do I need to change in Box2D to work in pixels? Box2D seems to be set up in such a way that you cannot work in pixels (i.e. physics scale 1). It produces very strange results as it hits maximum speed limits at low speeds and looks very strange. It only seems to work well at a physics scale of around 15 or 30. For me, working in pixels is the logical way to handle physics and movement in a game, as you are already using that measurement for lots of other things. I don't want to have postionX 30 all over my code, so what variables do I need to hack in the box2d source in order to make physics scale 1 work as if it was physics scale 30? I'm using the latest version from box2dflash.org. |
32 | What type of dashboard should I create to understand how my game is performing? This is a two part question. Let's say I release a new Flash game to the web. Once players start playing I want to understand how it is performing What common performance criteria do people track? (e.g. viral coefficient, play length, returning players.) How should I go about measuring and monitoring these attributes? Are there any off the shelf tools? |
32 | Does swf provide better compress rate than zlib for png image? Somebody told me that when a png image is stored in swf, it's separated to several layer, hence the alpha channel can be compressed better. Is it true? Or, once png image is imported into a swf, it's format is changed, e.g converted into bitmap data, and than compressed by swf's compress algorithm. That's, it is not in png format anymore. I don't know how swf packing its resource, please tell me if you know. |
32 | How can I find out what URL my game is executing from in Flash? I want to upload my game to Kongregate and other sites, but on Kongregate I want to invoke one function and other sites I want run another function. How to check in AS3 where (I want to get host like www.kongregate.com or www.games.com etc) my game is? Or maybe you know other, better way to make this? |
32 | How to save the 3D surface to bitmap in Flash 11 Stage3D I have been using Stage3D to create some 3D app in Flash. One of the items on my list is the ability to take a screen shot. Flash makes it easy to grab the stage content, but I can't find a way to grab the stage3D content. In DX I just used D3DXSaveSurfaceToFile. Anyone know of a way to do it in as3 and flash 11? |
32 | Can a texture's UV coordinates be animated (scrolled) when part of a SpriteSheet? Alright so my question is about texture manipulation in Flash Stage3D Context3D using AGAL for the shader language. But I'm pretty sure this could be applicable in other situations involving GPU programming. So the goal is, if I wish to have a "scrolling" animation on a certain tile (like a tile of water), can I still have that texture packed along with all the rest of my sprite assets? Or does it have to be alone to avoid bleeding nearby assets? From what I can understand, when the FragmentShader samples the portion of the texture offsetted during a scroll animation, any coordinates outside the desired texture will reveal incorrect nearby textures. Some example to clarify Fluid motion (lava, water waves, acid bubbles) Background motion (cloud, trees, houses) Directional indicators (lines on a conveyor belt, race circuit dash regions) Do I need to use some extra operations to wrap the texture if it tries to sample beyond a certain point? How could those constraints be defined transferred to the FragmentShader? UPDATE To clarify, I would like to scroll only on 1 single tile that would be part of a SpriteSheet TextureAtlas (meaning, mixed with other existing sprites part of a game project). Imagine you had something like this (but better artwork, of course) So a 256 x 256 Texture with a "Wavy Water" tile in the top left corner (128 x 128 in dimensions). How would you write a shader that can scroll through ONLY the water portion to give a sense of motion without running over the adjacent textures (ex faces and cars). How would you handle situations where the Quad is much larger than the texture and could repeat many times as well in combination to being able to scroll it? |
32 | In Box2dFlash my b2body gets detached from my Sprite after I use setXForm() I have a scenario where I have red coin in a Carrom board game which should be moved outside of the visible window when it is pocketed, also if any coin either white or black is not pocketed in the next shot, the red coin should be replaced in the center of the board. Now my problem is WHEN I apply the setXForm() method to move the b2body of the red coin outside of the visible area of my flash window.It moves,there is no problem in moving the body,but WHEN i replace the b2body and sprite after the event of no coin falling , the b2body is detached and works as a separate entity having no connection with the sprite of the red coin. I'm not getting a clue as to what is happening, that is why I thought I'd try posting this here. |
32 | Box2D Bicycle Wheels Motor Problem Flash 2.1a I have made a bicycle with Box2D using several polygons for the frame at different angles connected using weld joints, and I have revolute joints on the wheels with a motor. I have made some basic terrain (straight ground and a small ramp) and added keyboard input to control the bicycle with torque to balance it. All of this is done in with Box2D's Debug Draw. When the bicycle is on its back wheel but diagonally forward (kinda like this position ) the motors just cause it go spinning backwards over when in reality it should either stay on its back wheel or go down onto both wheels. Here's my code the revolute joints Front Wheel Joint var frontWheelJointDef b2RevoluteJointDef new b2RevoluteJointDef() frontWheelJointDef.Initialize(frontWheelBody, secondFrameBody, frontWheelBody.GetWorldCenter()) frontWheelJointDef.enableMotor true frontWheelJointDef.maxMotorTorque 10000 frontWheelJoint world.CreateJoint(frontWheelJointDef) as b2RevoluteJoint Rear Wheel Joint var rearWheelJointDef b2RevoluteJointDef new b2RevoluteJointDef() rearWheelJointDef.Initialize(rearWheelBody, firstFrameBody, rearWheelBody.GetWorldCenter()) rearWheelJointDef.enableMotor true rearWheelJointDef.maxMotorTorque 10000 rearWheelJoint world.CreateJoint(rearWheelJointDef) as b2RevoluteJoint And here's the relevant part of my update function up and down control wheels motor if (up) motorSpeed 0.5 if (down) motorSpeed 0.5 left and right control cart torque if (left) middleCentreFrameBody.ApplyTorque( 3) gearBody.ApplyTorque( 3) firstFrameBody.ApplyTorque( 3) secondFrameBody.ApplyTorque( 3) rearWheelToChainBody.ApplyTorque( 3) chainToFrontFrameBody.ApplyTorque( 3) topMiddleFrameBody.ApplyTorque( 3) if (right) middleCentreFrameBody.ApplyTorque( 3) gearBody.ApplyTorque( 3) firstFrameBody.ApplyTorque( 3) secondFrameBody.ApplyTorque( 3) rearWheelToChainBody.ApplyTorque( 3) chainToFrontFrameBody.ApplyTorque( 3) topMiddleFrameBody.ApplyTorque( 3) motor friction motorSpeed 0.99 motor max speed if (motorSpeed gt 100) motorSpeed 100 rearWheelJoint.SetMotorSpeed(motorSpeed) frontWheelJoint.SetMotorSpeed(motorSpeed) Any ideas what might be causing this?

32 | Flash AS3 sidescrolling tiles optimization I'm trying to make a sidescrolling game in Flash that will run on a low performance laptop. While studying the subject from Tonypa I saw that he builds a Bitmap by making copys of the BitmapData of each tile from the Tile Sheet and placing it on the bigger Bitmat with the size of the screen. But when I came to think on how to scroll my map I ran into some optimization doubts. I came up with two choices Create a MovieClip, place a Bitmap instance for each tile that is shown on the screen 1 row in it, then move them all. Then when the tile ran off the screen I would move it to end of the MovieClip and replace their BitmapData for the next row in my map. Use a Bitmap with copys of each tile in it (as shown in Tonypa's tutorial) but 1 extra row, move the whole Bitmap, and when it comes the time to replace rows, redraw the whole Bitmap and move it back to the origin position. The first idea is how a co worker of mine suggested, the second one is my own, but none of us has enough technical knowledge to be sure on a technique that would be optimal in performance, can anyone help? |

32 | How can I manage an animated UI from ActionScript? I'm trying to code a game of Poker in AS3, using Flash Professional CS5 (although I try to keep as little code as possible in the .fla). When a player bets, for example, I need to be able to show an animation of some chips sliding into the center of the screen. After that happens, the AI decides what to do, and another animation of their chips occurs. Then a menu pops up so the player can choose their own next action. And so on. I started writing a UIBet interface with bet(amount) and raise(amount) methods and so on, that you would implement with a class extending MovieClip and fill in the methods with gotoAndPlays to various animations. But if I just have code that calls these graphics object like so playerUIBet.bet() aiUIBet.bet() menu.prompt() Then, if I understand Flash correctly, what'll happen is that the code will finish executing, and then all of those animations will happen simultaneously. How can I get these animations to happen sequentially? What if I want to insert pauses between them? Some kind of solution like this? What's the best way to do this in AS3? |

32 | Change the tilemap shown on stage in Flixel I am building a simple platformer using Flixel, beginning with the source code from Flixel creator's EZPlatformer . I would like to adjust the level's tilemap when the player sprite enters overlaps with a sprite representing a door. I use Flixel's built in function to track if the player overlaps the door sprite. exits is a class level variable public var exits FlxGroup I call this function in the Update event to check for overlap FlxG.overlap(exits,player,UpdateScreen) I successfully catch when they overlap, however when I try and load the new tilemap, the old one continues to show. I use this function to attempt to update the tilemap on the screen public function ChangeScreen() void load the screen and locations of sprites(e.g. player, exits) based on current screen switch(currentScreen) case 1 load tilemap level new FlxTilemap() level.loadMap(FlxTilemap.arrayToCSV(data1,40),FlxTilemap.ImgAuto,0,0,FlxTilemap.AUTO) add(level) break case 2 load new tilemap level new FlxTilemap() level.loadMap(FlxTilemap.arrayToCSV(data2,40),FlxTilemap.ImgAuto,0,0,FlxTilemap.AUTO) add(level) break I thought that I would need to first call remove on level to take it off the stage, and then call add on it, however, when I do that, the tilemap does not show up at all. What is the correct way to do this? |

32 | Is there a tool to import a sprite sheet into Flash as a frame based animation? I'm looking for a tool that can help create a Flash based animation given a spritesheet basically the reverse of Spriteloq.

32 | Create and use a Button class on AS3.0 I am currently working on a game and it is all going well. On the shop screen there are several buttons that affect the player's stats for when the player restarts the game. The button's names (with a text on the left), however, are rather cryptic and it's hard to figure out what they do unless you test or something. So the solution I came up with, is to create an InfoBox with an InfoText inside so that when the cursor is over the button it appears with the description, cost and etc. This I managed to do too however, the way I was about to do it would mean that I had to create 3 event listeners per button (CLICK, ROLL OVER, ROLL OUT) and, obviously, 3 functions connected to each event listener. Now, I don't mind much about having 1 event listener per button, for the click, but since the other events are just to make a box appear and disappear as well as display some text, I thought it was way too much of a mess of code. What I tried to do I created a new class called InfoBoxButton, and this is the class' code package import flash.display.SimpleButton import flash.display.MovieClip import flash.ui.Mouse import flash.events.MouseEvent public class InfoBoxButton extends SimpleButton public var description String public var infoBox InfoBox public function InfoBoxButton(description) this.addEventListener( MouseEvent.ROLL OVER, displayInfoText, false, 0, true) this.addEventListener( MouseEvent.ROLL OUT, hideInfoText, false, 0, true) private function displayInfoText() infoBox.infoText.text description infoBox.visible true private function hideInfoText() infoBox.infoText.text "" infoBox.visible false But now I don't have an idea how to associate it with the button, I have tried this public var SoonButton InfoBoxButton new InfoBoxButton("This is merely a test") The SoonButton is a button I made on the shopscreen, SoonButton is it's instance name, but I can't think of a way of associating one button to the other... I have been fiddling with the code for like 3 hours yesterday and no luck... can anyone give me some pointers on how I should go about doing it? EDIT I tried to trace the SoonButton after it is created like this public var SoonButton InfoBoxButton new InfoBoxButton("This is merely a test") trace(SoonButton, "whut?") and I got an error saying 1120 Access of undefined property SoonButton. if I separeted the first line a bit to public var SoonButton InfoBoxButton SoonButton new InfoBoxButton("This is merely a test") trace(SoonButton, "whut?") I would get the same error but two times, for each SoonButton... so clearly it must be the InfoBoxButton that isn't being created... what am I missing? |

32 | Mouse follow precision in flash I am trying to implement a simple movement for one of game objects in flash AS3. I am using mouseX, mouseY for my object to follow the mouse pointer. It works fine but the problem is the precision of the movement.

32 | Should all stats only exist on MySQL database for my Flash browser RPG? I'm creating a browser RPG in Flash which will have some multiplayer elements and in app purchases so security is a high concern. Would it be better to have all game stats like health and such exist only in the MySQL database and retrieve them every time I need them? The game is turn based, but that would still require very frequent connections to the database. I could use local copies to cut down on the number of connections, but I imagine that would make it much easier for people to cheat. |
32 | Better way than url encoded query stings to pass data from PHP to Flash? For the turn based browser Flash RPG I'm working on, I'm using url encoded query stings to pass data from PHP to Flash. Basically, Flash posts a request to PHP, then PHP pulls some data from a MySQL database, does some calculations and echos something like "health 100 amp mana 50 amp strength 10" which Flash reads. It seems to work fairly well, but I'm wondering if there is a better way to do it? As I go along, the number of character stats is increasing, and after inventory slots, it will probably be around 100 variables. All that only needs to be pulled from the MySQL database through PHP once at the beginning though, with much smaller queries during gameplay. |
32 | Stencyl or flash limitation? I have found that Stencyl doesn't seem to be very good at handling very many actors in a game. I had been trying to implement some basic AI at the moment all the behaviours were wander (pick a random point and move directly to it) and wrap around screen (if it goes off the top of the screen it appears at the bottom). Even with these simple behaviours and calculations the frame rate dropped dramatically when there were more then 50 actors on screen 10 actors 60fps 50 actors 30 50fps 75 actors 30fps 100 actors 15 20fps 200 actors 8 10fps I had planned on having a maximum of around 200 actors but I see that's no longer an option and implementing a more complicated AI system with flocking behaviour, looking at creating a game in a similar vein to flOw. I understand that a game is perfectly playable at 30fps but this is a super simple test with ultra simple graphics, no animations and no sounds is child's play in terms of calculations to be made. Is this a limitation with Stencyl or is it flash? Should I simply scale the scope of the game down or is there a better game engine that exports to .swf that I should look into? |

SWF(width "640",height "480",backgroundColor " 000000") public class MyGame extends FlxGame public function MyGame() super(320,240,PlayState,2) forceDebugger true In the override of create() in the PlayState.as file I attempt to set the camera to follow the player as follows public var TheClimber BalloonHero override public function create() void set background color FlxG.bgColor FlxG.BLUE Set data for player TheClimber new BalloonHero(FlxG.width 2 5,480) Add camera and set it to follow The Climber which will automatically set the boundaries of the world. FlxG.camera.setBounds(0,1280,640,1280,true) FlxG.camera.follow(TheClimber,FlxCamera.STYLE PLATFORMER) add player to the game add(TheClimber) I assumed this would set the camera bounds to twice the height of the SWF background(i.e. the FlxG height) and then scroll the background along with the specified FlxObject(TheClimber in this case) until it had reached the height of the game. However, I must be going about it incorrectly because when the zoom is 2 and the game height 720 the camera starts at the top of the screen with the player character not visible at the bottom of the game height. Is there a way to start with the camera game focused on the bottom of the game object(FlxG.height) ? Or am I going about this the wrong way and have other issues with the way I am using the camera? Thanks in advance. |
32 | How do I make a custom tileset for Flixel that supports autotiling? I've been Googling this problem for a while now. I'm currently porting one of my Java games to Flixel, and I want to use the original 16x16 tileset I made. In the original game I implemented my own autotiling system, but I would prefer to use Flixel's autotiling system. However, I cannot determine how to lay out my tileset, or how to tell Flixel to use it. I have two different types of tiles, and I want both types to autotile to connect with tiles of the same type but not tiles of the other type, if possible. |

32 | Camera and enemy behaviour in AS3 platformer beginner in AS3 here. I am working on a platformer game based on the code of a provided example exercise. I have the following problem I have an enemy who shoots bullets. The enemy is the parent, and the bullet are the child. When I move to the next scene (level), the bullets are still there, but invisible, even using the removeEventListener to shut down the bullet hit check. Here is the code of the child "disparoEnemigo mov" addEventListener(Event.ENTER FRAME, fl MoveEnemyShot) function fl MoveEnemyShot(event Event) try if (enemy shot.y lt 300) if (enemy shot.hitTestObject(Object(this.parent).mario)) variablesGlobales.variables().vidas 1 Object(root).texto.text variablesGlobales.variables().vidas.toString() trace("vidas " variablesGlobales.variables().vidas) if (variablesGlobales.variables().vidas lt 1) MovieClip(this.parent).gotoAndStop(2) this.parent.removeChild(this) removeEventListener(Event.ENTER FRAME, fl MoveEnemyShot) else enemy shot.y 3 else trace("LLEGADA") removeEventListener(Event.ENTER FRAME, fl MoveEnemyShot) this.parent.removeChild(this) catch (error Error) removeEventListener(Event.ENTER FRAME, fl MoveEnemyShot) import flash.events.Event import flash.media.SoundMixer addEventListener(Event.ENTER FRAME, fl EnterFrameHandler) function fl EnterFrameHandler(event Event) void try if (this.hitTestObject(Object(this.parent).mario)) SoundMixer.stopAll() var sound gameOver new gameOver() sound.play() Object(this.parent).mario.y 1000 Object(this.parent).mario.x 15 trace("Mario dies") var cartel StageLose new StageLose() stage.addChild(cartel) cartel.x 85 Object(this.parent).mario.y 1000 catch(error Error) removeEventListener (Event.ENTER FRAME, fl EnterFrameHandler) And this is the code of the parent, "enemigo mov" var leftPressed Boolean true var rightPressed Boolean false stage.addEventListener(Event.ENTER FRAME, fl MoveEnemy) function fl MoveEnemy(event Event) try if (leftPressed) enemy1.x 0 if (enemy1.x lt 120) leftPressed false rightPressed true else if (rightPressed) enemy1.x 1 if (enemy1.x gt 120) rightPressed false leftPressed true var number Number Math.random() if (number lt 0.05) amp amp variablesGlobales.variables().coleccionEnemigos.indexOf(this) ! 1) trace("creation") var disparo disparoEnemigo mov new disparoEnemigo mov() this.parent.addChild(disparo) disparo.x enemy1.x 115 disparo.y enemy1.y 115 disparo.z 50 trace(disparo.x " " disparo.y) catch(error Error) removeEventListener(Event.ENTER FRAME, fl MoveEnemy) In both codes, "mario" is the player character. What I need to do is to stop the bullet creation of ""disparoEnemigo mov" when we move to the next scene. Shouldn't the "removeEventListener(Event.ENTER FRAME, fl MoveEnemy)" line stop the bullets to check if there is any collision with the player? Any help or resource will be helpful.

32 | Flash server, protocol protection I am making a flash game that will interact heavily with the server. For quite some time already I am using 'request hashing' technique to make sure that request data hasn't been tampered with. This works pretty well. However, in this game I'd like to go a little bit further and completely hide the protocol from the observer (right now it's plain JSON). I imagine that I could zip and encrypt data (using one of symmetric algorithms). That would make it pretty unreadable by human, right (also smaller)? And SWF encryption obfuscation should protect the encryption key (it is being done anyway). As a side benefit that will also protect dynamically loaded resources from directly saving them to disk (or copying from the cache). Questions are there tools that allow you to simply dump the SWF with all its content, received and decrypted? If yes, this will render 'the side benefit' invalid. do you think it's worth it to burn all that CPU power? To support my point, I will say that I like to inspect data being exchanged between client and server. And occasionally I find a bug or two which I can use to my benefit. But then there was a game that was sending and receiving some binary data. Being a lazy attacker, I decided not to analyze further. Otherwise, who knows what I could find ) Comments, ideas, criticism, suggestions? ) |

32 | Need help in determing what, if any, tools can be used to create a free Flash game Yes I proudly and sadly declare that I am a complete nincompoop when it comes to Flash, and I have been fishing around the big wide web for information. The reason for this is that I have been contracted to create a game(s) for a website the usual flash based games caveat. Please I do not mean things like by those gaming generator websites, I mean small yet professional games but the caveat, as always, is that impossible dream it needs to be done all for free. The budget...well imagine it as not there. Annoyingly is that I am a game designer yes, but with a ridiculously tight deadline I haven't got much time to re learn (ah the heady days of programming at uni) everything by the end of March, so I'd like to ask some people who know their stuff rather than keep looking at a gazillion different things. This is my understanding with the flash sdk you can create a game, albeit you need to be pretty programming savvy. FlashDevelop helps there yet I am not entirely sure how. Yet even FD says to use Flash for the animation graphics. Yes its undeniably powerful but as I said there is the unattainable demand of no money. The million dollar question what, if any, tools can I use to create a free flash game? |

32 | AS3 Increase tint as health decreases I'm working on a game where enemies continually spawn with more and more health based on how long you've been playing. As the enemies take damage, I'd like their sprite to get darker and darker, until they die. Here's what I've got so far enemy array i .health damage healthcolor.setTint(0x000000, enemy array i .health 0.1) enemy array i .transform.colorTransform healthcolor Predictably, this is making enemies get less black as they take damage. What I need is to convert the decreasing enemies' health into an increasing number between 0 and 1. I have absolutely no idea where to begin. It's entirely possible I have tunnel vision, but I'm hoping someone here might have an idea for how to accomplish this. Thanks for your time. |

However, while the Starling graphics are correctly upscaled, they only occupy the upper left corner of the screen, and the remaining three quadrants are cut off. I haven't validated yet, but I suspect that the segment being displayed is the same dimensions as the original windowed stage size. Any ideas on what I'm forgetting to do to achieve fullscreen Starling displays that are actually fullscreen? This is on OSX. |
32 | Fixed timestep with interpolation in AS3 I'm trying to implement Glenn Fiedler's popular fixed timestep system as documented here http gafferongames.com game physics fix your timestep In Flash. I'm fairly sure that I've got it set up correctly, along with state interpolation. The result is that if my character is supposed to move at 6 pixels per frame, 35 frames per second 210 pixels a second, it does exactly that, even if the framerate climbs or falls. The problem is it looks awful. The movement is very stuttery and just doesn't look good. I find that the amount of time in between ENTER FRAME events, which I'm adding on to my accumulator, averages out to 28.5ms (1000 35) just as it should, but individual frame times vary wildly, sometimes an ENTER FRAME event will come 16ms after the last, sometimes 42ms. This means that at each graphical redraw the character graphic moves by a different amount, because a different amount of time has passed since the last draw. In theory it should look smooth, but it doesn't at all. In contrast, if I just use the ultra simple system of moving the character 6px every frame, it looks completely smooth, even with these large variances in frame times. How can this be possible? I'm using getTimer() to measure these time differences, are they even reliable? |
32 | How to achieve smooth sprite movement with a scaled up canvas? I'm developing a simple 2d platformer using haxe amp openfl (currently targeting flash).

32 | Is Scaleform Flash used in console games for non UI, game elements? I work for Konami as a Flash developer, and got sent some code for a puzzle mini game from a new, yet to be released Silent Hill game for PS3 Xbox 360. It was a windows executable, but it was made in Flash, and I saw some GFX (Scaleform) libraries in the source. I was very surprised by this, as I thought the extent of Flash's reach into console games was simply for UI. Granted, this was an essentially 2d, UI centric puzzle minigame, but nonetheless, this was a gameplay useage of Flash Scaleform in a "next gen" console title. My question is, how prevalent is this? I really want to get into console programming, and if this is something that appears elsewhere, maybe I can apply my Flash Actionscript skills to getting a job working on console titles. Anyone have any thoughts or experiences with this? Thanks! |

32 | Game Server Framework Engine that supports AMF? I am looking for a server technology that supports AMF (because I plan on using an as3 flash front end). I would like to develop game logic simulations that run on the server. Small number of users and logic at first, but that will grow. I might use this for some simple turn based simple tests, but I am hoping this will also support some tougher real time (RTS) or even MMO style games and simulations. So far I have been looking at (in order of what I think is most promising so far) WebORB Looks the most promising so far, appears to be well supported and developed, lots of features, yet sells itself as easy. Looks like they have a community open source free version Cubeia Firebase Looks really good, only thing that worries me is their statement that it does not work well for real time style games, but is ideal for turn based. It might be ok for now, but what if I need to scale the game up? Open Source Free BlazeDS Looks promising, supported by adobe, I should be able to develop game logic in the BlazeDS server and has amf support. Open Source Free Red5 No release since 2010, some activity though. (has amf) Open Source Free however have not been able to locate any good 'game' examples tutorials.

32 | How should I do my collision response? I'm making a small lockpicking simulator. Obviously I'll need the pick to not pass through the lock, and I'll need the pins to move when you tap or push them with the pick. Here's what I have so far, just to give you an idea. http megaswf.com serve 2433982 As you can see, the collision detection is pixel perfect. I've looked into a couple of different ways of doing collision response, but it seems like such a vast and complicated field. Any time I come up with a possible solution I start noticing flaws like what would happen if more than two objects collided and so on. I've looked into physics engines like Box2D, but it seems like such overkill considering the, I think, simple nature of the game I'm trying to make. I don't like the idea of using a huge library that I don't even begin to understand just because I can't figure out how to do collision response. But I just don't know where to begin. Maybe I will have to use a library. If anyone with experience could, based on that demo and what I'm trying to do, suggest a course of action, I'd really appreciate it. |
32 | How do I ensure an appropriate payout ratio for a slot machine? I have done a lot of research into random number generators for slot machines, reel stop calculations and how to physically give the user a good chance on winning. What I can't figure out is how to properly insure that the machine is going to have a payout rating of (lets say) 95 . So, I have a reel set up wit 22 spaces on it. Filled with 16 different symbols. When I get my random number, mod divide it by 64 and get the remainder, I hop over to a loop up table to see how the virtual stop relates to the reel position. Now that I have how the reels are going to stop, do I make sure the payout ratio is correct? For every dollar they put in, how to I make sure the machine will pay out .95 cents? Thanks for the ideas. I am working in actionscript, if that helps with the language issues, but in general I am just looking for theory. Edit There is real money involved only in the fact that they can buy more tokens to play more. There is not going to be real money paid out to the person, if they were to actually hit the any of the paylines. |
32 | Red5 or zendZMF or BlazeDS or Cirrus? I've been trying to develop a multiplayer turn based game which is mostly free to play I just want to see if the game idea is appreciated hence I want to do it with minimal cost and I'm confused which one of these to use red5, zendamf, BlazeDS or Cirrus. Red5 seemed the best option for me initially but getting a media server to host seems to be quite expensive. Same reason why I couldn't use Electroserver cost. Both are very attractive options though. ZendAMF then looked a feasible option since it supported remoting. But how do I let the other players get updates on actions of one player through zendAMF, which as far as I know does not do data push. I'll have to do it by polling asking server constantly for updates which wont look very real time. Then I heard about BlazeDS which does support data push. Now I have to learn java if I want to use that and get a new web host because my existing host does not have tomcat. Then I heard about cirrus which is still in 'codename cirrus' stage. It looks like a very feasible option since its peer to peer with miniamal server support needed. Is it good for a mutiplayer game? Well if anyone has experience developing multiplayer flash games I'd like to know if a turn based multiplayer game with more than two players participating can be implemented using zendamf. ZendAMF because I know PHP and AS3. |

32 | How to produce assets effectively on large Flash game projects? I have been working on Flash games professionally for two years now and somehow, having our artists producing assets the right way is one of our biggest challenge. More precisely, it is very hard to have them following any kind of structure and or standards, nor taking into consideration performance. I would say also the most of our issues concerns UI and related animations. Our current workflow is (on a Facebook hidden object game) Artists produce PSD and animate prototypes in Flash Artists re organize their FLA files to be a bit more "programmer friendly" Programmers retouches assets until they have the right structure and export classes inside a SWC, from Flash Programmers try to improve performances, sometimes degrading the quality of game graphics Our main idea is to hire somebody dedicated to prepare assets for programmers but I am really looking forward to improving the pipeline. I was wondering if you guys have tips of any kind to improve this workflow, whether it be team organization, training, tools or tips with Flash. Any explanation on your asset pipeline is well appreciated too. EDIT Thanks for your replies. I do agree with you that tools and processes will never replace collaborative people. However, I feel like we got stuck into this "I am doing my own thing" mentality as the integration process caused a lot of friction. As part of our Scrum process, the team clearly acknowledge its own quirks and was looking at immediate solutions for the next project better rules, better attitude, better understanding of each other. My team have specialized artists (UI, character drawing, character animation), but no leading art director (we use existing licenses brands), and programmers (both front and back end). That's why having a very versatile person in between (designer, integrator, technical artist or however you want to call it) is invaluable in my opinion so, I am looking for innovative solutions. Usually, the main specs requirements for assets are Naming (of classes, textfields or various visual objects that will be used by the code, taking in account that visual needs can cause deep nesting of objects) States (that we implemented with frame labels) Alignement (always build from 0,0 use round values) So, while adopting "good practices" can sure help, there always is this little part of feature specific requirements that has to be decided. Basically I was looking for a an efficient way to communicate these specs (even to non technical people) and avoid the back and forth to verify assets are as expected (this is where my idea of intermediate validation format comes from). I understand there is no clear answer and I created this post to get people feedback and good ideas (it's working so far ) |

I believe they have limited connection versions available and while I am hoping to scale my project above those limitations I do not expect to be drawing an income to pay for the licenses at that point LCDS (live cycle data services) similar to blazeDS, not free Any other options or clarifications?? |
32 | Is frustum culling necessary in a Flash AS3 game? I'm making a 2D game where the map will be scrolled frequently, and only a small part of it will be visible at any time. Which implementation would run faster? The naive way Make the map a single huge MovieClip and move it around. The elegant way Split the map into multiple chunks and use a frustum culling algorithm to render only the ones that are visible. Now that I think of it, this question boils down to whether Flash does its own frustum culling on big MovieClips. |
32 | Rendering performance for Flash games I was reading on SO about native flash rendering vs building a custom BitmapData frame buffer and some of the answers were a bit conflicting, so I was wondering Is it generally best practice to go the custom Bitmap buffer route or is it best to leave rendering to the flash engine? If you're using vector animations (MovieClips) as opposed to sprites, does that change the answer to the above? If so is it best practice to use sprite based animations? (I'm targeting Flash 10 if that makes any difference) |
33 | Using sprites in pygame without classes and objects Relevant information I'm in a grade 11 computer science class that uses Python amp Pygame. We're aloud to use sprites and images though we're never taught it, just drawing graphics like squares and circles. We were taught arrays, lists, functions but not classes and objects. We also relatively do things without using functions like the init main one I see a lot on line, we also don't use self or super. If it's anything relevant, I'm making a top down (bird's eye view) 2D shooter game similar to a 2D version of dead ops arcade in Call Of Duty Black Ops. What I'm trying to do I've been programming with Java amp LibGDX before hand. So I want to use sprites in images in Pygame the same way I've been using it in LibGDX. Getting images, obtaining image rectangles for collision, rotating transforming images, changing the images of the sprite. Though every tutorial I've seen for sprites and images in Pygame that I can search up uses objects, classes and function calls that I'm not familiar with. What I've done I've loaded a PNG into my program and drew it to the screen. Simple and straight forward. Though the Pygame documentation doesn't give me a lot of options in terms of manipulating these images other than moving their location. What I'm asking for A simple run down syntax of how I would use a sprite in Pygame, without objects classes or any weird function terminology. In terms of functions I can make a function, pass information through parameters and return values. I'm not aware of global variables, self or super. The simplest of simple where I can resize an image, change the image of a sprite, transform rotate it, and get a rectangle that I can use to overlap with another one. |
33 | Common practice when handling sprite animation Let's say I'm using the following sprite as a sample to try LibGDX Animation and TextureRegion. http www.smackjeeves.com images uploaded comics 7 8 78bc6b62fEySW.gif As you can see, the provided image above has different width amp height per image. The width when Zero performs a slash is different when Zero stands. Is it a good practice to create a padding margin for every image so they have similar width amp height. Or should I just have all the sprite cramped like that and try to handle it in the backend? Thanks |
33 | What approaches are there to re designing 8 16 bit sprites for HD? I'm new to game development, and my skills with Photoshop are not that great. I was planning to try to convert a old game to HD, but for this I need HD sprites. What is a good way to approach converting 8 16 bit sprites into something like HD? I mean something like this |
33 | Sprite cut in half after placed on Scene I have noticed a very odd behaviour in Unity 5.2.1. When I drag and drop a Sprite into the Scene, it's cut in half like this I tried with PNG and PSD formats but it didn't help. Although when I flipped an image horizontaly in PS and then imported it, it worked. Is this a Unity bug? Edit It happens only when I set Max Size to 512 or more, but still why? |
33 | How can I quickly check if my sprite tiles well? I am trying to create tilemap sprites that tile nicely, but checking how well they tile is really cumbersome. Ideally, I'd like to have an image editor that shows a layout like this, so I could see if it tiles well without a manual check img img img img img What programs can do this, or how can I otherwise make this easier? |
33 | Revolve FlxSprites Around a Central FlxSprite in Flash Game made with Flixel I have been working on a Flash game made in Flash Builder using the Flixel library. I have been trying to dynamically create a group of FlxSprites , and revolve them around a player controlled class that extends FlxSprite when the player uses a power up. My thought on how to approach this, was to create a circle, use points on that circle to instantiate the sprites, and then somehow update those sprites to points along that circle during the game's update step. But I am not sure what would be the best way to hold information about a circle, or circular path's in ActionScript 3. I assumed that As3Math provided some of the means to do this, and I tried to add one sprite to a circle like this package import As3Math. import As3Math.geo2d.amBoundCircle2d import org.flixel.FlxGroup import org.flixel.FlxState public class ButterflyRing extends FlxGroup Embed(source ".. Content Images spritesheet butterfly 32x8.png") var butterflySprite Class public function ButterflyRing(playState FlxState,X Number,Y Number) add to super class super() create a circle motion path at coordinates x 150, y 150 with a radius of 100 var butterflyCircle Math.amBoundCircle2d new Math.amBoundCircle2d(150,50) var circDiameter Number butterflyCircle.radius 2 var pX Number butterflyCircle.center.x circDiameter var pY Number butterflyCircle.center.y var butterfly SpriteButterfly new SpriteButterfly(pX,pY) add(butterfly) override public function update() void super.update() I realize now this is not the correct way to use As3Math, that it is accessible by default and you call it like Math.pi. My question is, Does ActionsScript 3 have the means to do this in its code base, or do you have to define your own classes to hold information for a circle, or do you use Math.pi to build circles from scratch? What is a good approach for this? Or does Flixel provide something good for this? |
33 | Why are 16 16 pixel tiles so common? Is there any good reason for tiles (e.g. Minecraft's) to be 16 16? I have a feeling it has something to do with binary because 16 is 10000 in binary, but that might be a coincidence. I want to know is because I want to make a game with terrain generation, and I want to know how big my tiles should be, or if it doesn't really matter. |
33 | Slicing irregular spritesheet (automatically?) If found a cool sprite sheet on the internet but its irregular. Is there any way besides manually cutting sprites to extract the separate pngs? I need to pack them then again into the Texture Atlas under proper names. Maybe theres some smart online tool that uses deep learning or something like that? |
33 | Gamemaker images appear blurred in application I'm making a practice game (generic space invaders clone) in Gamemaker Studio. However, there appears to be a problem with the images. While they look acceptable in Gamemaker Studio (not amazing, due to stretching effects, but acceptable for a practice project) However, once I compile the project down to an application I get this blurring effect Can anyone tell me what's causing this, and how to turn it off? |
33 | Problem with preloading plist file in Cocos2d x I am using Cocos2d x engine with 3.2 version. In my splash screen I am prefeching a plist by below line SpriteFrameCache getInstance() gt addSpriteFramesWithFile("ui.plist") Now inside game when I am creating a sprite I am getting an assert fail error Sprite ss Sprite createWithSpriteFrameName("pause.png") Assert failed Invalid spriteFrameName pause.png Also when the splash screen is removed, I am getting the below line in console cocos2d TextureCache removing unused texture D cocos2dx projects ABCD Resources mid ui.png Is there anything I need to add or something? I was doing the same thing for 2.x and was working but not in 3.2 EDIT In 3.x if you are calling this line Director getInstance() gt purgeCachedData() , remember that it will delete all textures from the cache memory. So handle all sprite sheets manually. |
33 | How do you move a sprite in sub pixel increments? Pixels are either on or off. The minimum amount you can move a sprite is a single pixel. So how you make the sprite move slower than 1 pixel per frame? The way I did it was to add the speed to a variable and test if it had reached 1 (or 1). If it did, then I would move the sprite and reset the variable to 0, like so update(dt) temp dx speed dt temp dy speed dt if (temp dx gt 1) move sprite reset temp dx to 0 if (tempy dy gt 1) move sprite reset temp dy to 0 I disliked this approach because it feels silly and the sprite's movement looks very jerky. So in what way would you implement sub pixel movement? |
33 | Rotate sprite direction Cocos2d I want that my sprite go always forward, and you can only control his direction moving right and left (on 360 degrees). I don't know why, but the movement it's senseless. The constants to move and rotate const int POD DEGRE MOVE 5 const int POD STEP MOVE 3 The sprite initalization dragonSprite gt setPosition(Point(visibleSize.width 2, dragonSprite gt getContentSize().height 0.75)) addChild( dragonSprite, 2) The event key listener void GameScene onKeyPressed(EventKeyboard KeyCode keyCode, Event event) pressedKey keyCode switch ( pressedKey) case EventKeyboard KeyCode KEY LEFT ARROW giro POD DEGRE MOVE isMoving true break case EventKeyboard KeyCode KEY RIGHT ARROW giro POD DEGRE MOVE isMoving true break void GameScene onKeyReleased(EventKeyboard KeyCode keyCode, Event event) if ( pressedKey keyCode) pressedKey EventKeyboard KeyCode KEY NONE isMoving false giro 0 And the calculations of the new direction void GameScene update(float dt) dragonSprite gt setRotation( dragonSprite gt getRotation() giro) podVector Vec2(cos( dragonSprite gt getRotation()) POD STEP MOVE, sin( dragonSprite gt getRotation()) POD STEP MOVE) Vec2 newPos Vec2( dragonSprite gt getPosition().x podVector.x, dragonSprite gt getPosition().y podVector.y) dragonSprite gt setPosition(newPos) Another problem is that the sprite at the start moves to the right (because Cos(0) 1), so I rotate the image of the sprite 90 degrees to the right, to then rotate it again at the initialization 90 to the left so the sprite is in the right position and his start angle is 90 (sin(90) 1), but the angle is not 90, and it moves as he wishes. The last problem I have with this is that when I press a key (right or left), the sprite stops, rotates, and starts again (a direction that is not the direction where the sprite is aiming, that's the main problem). The sprite shouldn't stop while you are moving it. Can anyone help me? |
33 | How to prevent images from being resized in game maker? This warning appeared in the compilation menu of my game. The images were rescaled in half. I understand that this happened because they had very large dimensions. It turns out that the images, although they have a large size (pixels), are very light, because they are composed for the most part by simple traces in addition to having the transparent background. Below, one of the images You see, it is very light. It turns out that in the game it stops being clear. How do I solve my problem? Using smaller images is out of the question. |
33 | Tiled map editor and objects Ive been searching for an easy way to group multiple sprites of a spritesheet into a single entity. Im using tiled editor as written at the title.

I dont want to create new tilesets with different sizes for all objects. Is this possible in this app and if not do you know another that can handle this? |

33 | How to avoid the cutoff of a Sprite when overlapping in a terrain? I have a scene where I have a terrain as a PlaneGeometry. And I'm trying to locate a building on it as Sprite. But I'm not able to put that building sprite centered on the terrain without getting a cutoff. Make sense because the terrain is cutting the half. But I'm just wondering if there is a technique to solve this problem. I tried to rotate the sprite as a 3D object. But does not have this property. Also tried using a PlaneGeometry with a MeshBasicMaterial, but the result of the Image looks blurry and without transparency. |

33 | MonoGame sprites not consistently drawing Please don't mark this as a duplicate of my previous question which was asked anonymously. this is a reattempt because i cannot edit the first attempt. What I have so far is randomly generated tile set with items on SOME tiles one creature spawner that spawns up to 5 creatures which can be controlled by the player the ability for creatures to pick up items and bring them back to the spawn and store them for later use What I am noticing is when i launch the game, it doesnt always show all the sprites. Sometimes the spawner is missing, or the creatures, or the GUI. ANd when things DO appear, if i tell the creatures to pick up anything, other items on the ground randomly appear and disappear. even the spawn sometimes disappears! what I do notice is that when i have multiple creatures, some will disappear when crossing invisible lines but not all of them. i forced two creatures to go east at the same speed and time, and one vanished and the other didnt. If you have any ideas as to what might be causing this, please let me know. if you have any questions, i'll try to edit to appease you. thanks for reading! I have my draw method like this GraphicsDevice.Clear(Color.CornflowerBlue) TODO Add your drawing code here spriteBatch.Begin(SpriteSortMode.BackToFront, null, null, null, null, null, camera.GetTransformation()) worldEntity.Draw(spriteBatch) guiManager.DrawGUI(spriteBatch) spriteBatch.End() base.Draw(gameTime) for the world entity... its draw method systematically goes through each tile in the world and calls its draw method. the tile draws itself using Vector2 topLeftOfSprite new Vector2(this.X, this.Y) Color tintColor Color.White spriteBatch.Draw(tileTexture, topLeftOfSprite, tintColor) and then proceeds to call the draw method of any items on it. creatures and items have very similar draw methods. the gui also draws itself in a similar fashion. what i DO notice is that ive NEVER seen ground tiles vanish, only the items on them or creatures in the world. Could it be their Z isn't set appropriately? |
33 | how to re use a sprite in cocos2d x some times it takes time to create the sprite structures in the scene, I might need to setup structures inside this sprite to meet requirement, thus I would hope to reuse such structures with the game again and again. I tried that, remove the child from parent, detach it from parent , clean parent with the sprite. but when I try to add the sprite to another scene, it's just wont pass the assertion that the sprite already have parent did I miss some step ? add an example I have a sprite A which involves of quite a few steps to construct, so I used it in scene A layer A, and then I want to use it in scene A layer B, scene B layer A1 etc..... generally speaking I don't want to reconstruct the sprte again. |
