7 | libgdx continuous movement while touch and hold (even after jump)? So, I have these buttons where I have implemented a method to handle 'touch and hold' (without polling). If the player touches and holds the walk button ..it will keep walking till the button is released. Problem is when I combine jump with it ... In the update method, if (activeTouch) translateScreenToWorldCoordinates(touchCoords.x, touchCoords.y) if (touchPoint.x lt 5) Code for walk left else if (touchPoint.x gt VIEWPORT WIDTH 5) Code for walk Right else if ((touchPoint.x gt 6 amp amp touchPoint.x lt VIEWPORT WIDTH 6) amp amp player.isGrounded() amp amp player.getState() ! Player.State.Falling) Code for Jump The touchdown and touchup events, public boolean touchDown(int screenX, int screenY, int pointer, int button) touchCoords.set(screenX, screenY) activeTouch true return false Override public boolean touchUp(int screenX, int screenY, int pointer, int button) activeTouch false return false So i can move right,left and also jump. But my problem is, while walking if I jump ... it will jump and then stop walking. How to continue walking after the jump if the player is still holding onto the walk button? |
7 | Switching from OpenGL ES 1.0 to 2.0 I have been developing an Android app using OpenGL 1.0 for quite some time using a naive approach to rendering, basically making a call to glColor4f(...) and glDrawArrays(...) with FloatBuffers each frame. I am hitting a point where graphics is becoming a huge bottleneck as I add more UI elements and the number of draw calls increases. So I'm now looking for the best way to group all of these calls into one (or two or three) draw calls. It looks like the cleanest, most efficient and canonical way to do this is to use VBO objects, available from OpenGL ES 2.0 on. However, this would require a HUGE refactoring on my part to switch my whole graphics backend from ES 1.0 to ES 2.0. I am not sure if this is a good decision, or if there are acceptable ways to group my drawing calls in 1.0 that would work fine for relatively simple 2D data (squares, rounded rectangle TRIANGLE FANs, etc.), or if it really might be worth biting the bullet and making the switch. I might also mention that I have a HEAVY reliance on translation and scaling that is so convenient with the fixed pipeline of ES 1.0. Looking around, I am surprised to find almost NO people in my position, talking about the tradeoffs and complexity at hand for such a switch. Any thought? |
7 | Speed up loading of png files (used for textures) in Android OpenGL Game My game has a few texture atlases that need to be loaded (in my XHDPI folder they total 3.49MB) and on a top end device they don't take that long to load, however on a low end device they seem to take an age. An example would be my old Samsung Galaxy Ace which uses the MDPI folder for it's resources (total 1.51MB), this takes 16 seconds, which I personally consider far too long. Originally, I had a separate atlas for each sprite, so I merged the majority of my atlases into one big atlas after reading that it may speed things up. Unfortunately, it hasn't really made any difference to the load speed. This is how I'm loading my png files atlas BitmapFactory.decodeResource(view.getResources(), R.drawable.atlasimage) As the default load format is ARG B8888, I though I'd attempt to load them in RGB565 as this is supposed to be quicker to load and render as well as take up less memory. So I tried this BMFOptions new BitmapFactory.Options() BMFOptions.inDither false BMFOptions.inPreferredConfig Bitmap.Config.RGB 565 atlas BitmapFactory.decodeResource(view.getResources(), R.drawable.atlasimage, BMF Options) Unfortunately, although this does reduce the quality of the image, it doesn't reduce the load time and yields no noticible performance increase. Also, (and this may be expected), it doesn't reduce the memory footprint of my app. So my question is how can I optimise this so that my png's are loaded quicker (rendering speed increase not being as important at the moment as load speed). |

7 | How to read monogame log files on android device I am working on a monogame android project where I want to log some data. First try was something like this Log.Info(tag, message) This works great when debugging in Visual Studio via the Android Device Logging Window. But when I run the app on my mobile android device I have no idea how to view the log entries. As far as I know the logging happens in the so called CatLog, which can be viewed with some Apps. But unfortunately these apps need root access, which I think cannot be given to them on a "normal" android device. Is there any way to either view the Logfile on my Android device or is there a better way of adding logging to my project? Thanks in advance Nick |
7 | Word Search Game Issue I am developing a game like word search. I have used AndEngine for this and for displayig grid of words I have used TiledMap. In this game, we need to join letters to make a word as we drag our fingure it will draw line on tiles and make connection between letters. I am able to draw lines vertically and horizontally accurately but as I try to draw line diagonally it goes to the nearby tile and draw line from last touched tile to nearby tile. But as I carefully move to the diagonal tiles it draws line accurately. Can any one help me to solve this issue? e.g. 1 2 3 4 5 6 7 8 9 10 11 12 as shown in above e.g. I am able to draw line for "1234" amp "159", It means all horizontal and vertical positions works accurately. But for "963" its not as accurate as i draw for horizontal and vertical. I want to draw line on one board as shown above. There will be letters below lines and need to connect correct words. |

7 | How to decide to use OpenGL ES 1.0 or 2.0 for Android? I started learning some Android development and one of the first things I thought I could make is a simple game. However, I'm faced with one difficult question right off the bat. Should I use OpenGL ES 1.0 or 2.0? The game I have envisioned will be pretty simple graphically, utilizing 2D(tiled top down type graphics) and fixed camera isometric views. I've never used OpenGL in a desktop environment, so I'm oblivious on if shaders will be something I'll use, etc. According to this page I should use OpenGL ES 2.0 generally for new development. My own phone however just recently(past year) got an update to get it to the required Android 2.2. (I don't even know if it has OpenGL ES 2.0 support) So basically my question is, will I benefit from any of OpenGL ES 2.0's features over 1.0 and or is it worth it in terms of compatibility? |

7 | Best method for 2 layer tile based map scrolling What is the best general approach to implement scrolling for a 2D tile based game? I need to scroll the map with a constant speed, lets say 2 pixels every frame (like in a top down shooter). The tiles are 32x32 and the map is quite big, lets say 10 x 300. There are 2 layers first is the background layer second is the forgeground layer with obstacles and enemies The target plattform is android and I want to use OpenGl. What is best practice? a) Draw only the visible Screen all the time (every frame) b) Load complete map into memory and just move the camera Is there a difference in performance and determining collision etc.? Thanks for any help! |

7 | Reducing APK File Size by using JPG instead of PNG for game background images I've just finished my (openGL ES 2.0 Android) game and it's almost ready for Alpha testing. When I export the application to an APK File, the file is taking up 16MB and I would like to reduce this as much as I can. Here are some points about what the project contains and what I've tried to reduce the size already 222kb of Ogg Vorbis files used for Sound Effects 1 x MP3 file at 5.59MB (128kbps Bitrate) 4 x sets of PNG files used for textures (XHDPI, HDPI, MDPI amp LDPI I'm not using XXHDPI) Just over 1MB of code What I've tried thus far to get where I am I've optimised the PNG files using Optiping I've applied ProGuard to my code before exporting, this didn't really help by much as 99 of my app is resources. So my question is, is there really much else I can do to reduce the size of the APK? I was thinking about maybe using JPG format source files for my Background OpenGL textures instead of PNG anyone have any experience with this? Does it hurt performance at all? I can see that it would make quite a difference my atlas of backgrounds in PNG format for XHDPI is 1.7MB and a 90 compressed JPG comes in at around 650KB. I'm just not sure if it's a good idea as everyone always advocates PNG JPG. Any pointers from personal experience would be helpful amp also if I've overlooked anything other than using JPG's. |

7 | Are OpenGL Textures more memory efficient than Android Bitmaps? I have a custom application that deals with many Bitmaps tiles that are 256x256 images (png,jpg). I'm currently using the View 2d canvas and bring in all images as RGB 565. Although I'm generally happy with the applications performance, I have features I'd like to add that will require even more map tiles (Bitmaps). I've been thinking about using opengl ES 2.0 but am fairly new to it. Would opengl Textures be more memory efficient than keeping Bitmaps around? I assume you can load a Bitmap into a Texture and then dispose of the Bitmap Is it an acceptable practice in opengl to dynamically load many different Textures at runtime? Do you need to cache Textures or does the GPU handle that for you? |
7 | Which app markets should I deploy my Android game to? I just launched my Android game today. I'm curious to know where I can deploy it. Of course, Google Play is the veritable king of markets, and my own game site will be next. After that, which marketplaces are mature and are worth deploying to? I looked at SlideMe GetJar Soc.io And some other ones that I didn't use YAAM (kept crashing and erroring out) 1Mobile (couldn't figure out how to upload my app) Insyde Market My question is really, which ones are out there and are worth uploading too? (And 1Mobile seems good, but just can't figure out how to upload.) Each site requires their own size screenshots and logo, so it's a bunch of extra work. I'd rather stick to the 80 20 rule and apply 20 effort to hit 80 of the markets. |
7 | Can a 3g network work for this project and is my understanding correct? I want to make a game for the android phone using unity. As you can tell by my last post i wanted to use networking to make this happen. I decided unity would be a good choice and in no time i was able to have two android devices connect to a simple game using unity master server and i was able to see both of my cubes update in real time over both phones. My end goal is to make a game where you are a sphere and your goal is to knock your friends off the the arena(A sumo game). The arena will slowly get smaller until only 1 sphere is remaining. My question revolves around how doable this would be with a 3g network over the phone. It does not appear that unity3d has bluetooth support for android and i could not find a plugin for it anywhere. This would be ideal to have bluetooth local networking and if i am incorrect, please tell me. The way I understand cell phone data transmission is you have your cellphone and it sends the data to the cell tower. The closer you are to the tower the better. Does your relative position to one another(Two clients connecting ) matter if you are both in range of the same cell tower? While my cubes updated just fine I know that 3g can be spotty. Is 3g viable for this idea? Is bluetooth usable for android with unity3d if not? Thank you |
7 | How do I dispose of OpenGL resources cleanly on Android? I am creating a framework for OpenGL ES 2.0 for Android. How can I cleanly dispose of my OpenGL resources when my Android app is done? I check for isFinished() in the onPause() event and then dispose of the resources but it calls the OpenGL functions from the main UI thread so it gives me an error (0x501). When I try to call isFinished() inside my onDraw() in my GLSurfaceView.Renderer class, it is never called when I quit my app. Anyone got any ideas? |

7 | What is the right way to implement a loading screen in cocos2d js? We have two scenes that are loaded with heavy computation a map screen and a puzzle screen. When we change the scene from A to B, the app gets stuck on scene A for a while before it renders scene B. So to avoid confusion, we created a dummy scene with 'Loading...' written on it and then on it's onEnter function we change to scene B. The game now gets stuck on the dummy loading scene now instead. But the loading scene takes in touch inputs and the device's native button inputs and triggers it as soon as scene B enters. So the map scrolls if you swipe on the loading scene and puzzle takes input on tapping the loading screen. Has anyone implemented a proper loading scene with cocos2d js? |

7 | Is it worth planning to be cross platform in mobile game development? Disclaimer my goal is not to use cross platform frameworks like Unity. I am currently planning a mobile game which I intend to first launch on iOS. However, I am wondering if it is better to write everything in Objective C, thus locking the code into the platform, and to do a complete rewrite for other platforms (ie Android). The other option would be to write the game logic in C or C and to only write the code that interfaces with each OS in the preferred language (Objective C( ) or Java). I understand that this must depend on the size of the code base, so what program size should mark the separation? Finally, if I write cross platform code, should I stick to C (since Objective C is a superset of C, making it easy to use C and to use the code samples and because the NDK and the JNI interfaces are more C oriented)? The only advantage I see with C in that case is the fact that it is object oriented and thus it is easier to represent game entities). |
7 | Flash Professional vs FlashBuilder 4.6 for mobile app development From the marketing materials I see online, it seems to me that FlashBuilder 4.6 is a subset of the functionality available in Flash Professional. If I understand correctly, mobile app development target iOS and Android started as a plugin for Flash Pro and has since been made a separate product. But can Flash Pro still do all the multi platform targeting that FlashBuilder 4.6 can do? What other considerations are there between the two applications that are critical to understand for mobile app development? Thanks! |
7 | Really weird peaks when profiling a simple scene with Unity3D I need some help optimizing my game. I have spent last 3 days digging around with no luck. I have noticed really odd results in the unity profiler so, I have created a simple scene with just a cube and a camera, and again, really odd results. Could anybody have a look at this screenshots? You will see some significant peaks that make the frame time too high (30fps sometime or less). Scene hasn't any script, no coliders, no rigid bodies (notice the Physics simulate in one of the shots). Could anybody explain what is happening? PD. Target platform is Android. This are taken from a Nexus 4 device. PD2. Somebody can argue that this is not a real scenario, but I have had this problems in a real game myself and wanted to show a simple example to expose the problem. Thanks in advance. |
7 | Android Action Move when moving between specific screen areas OK so I know how to iterate through the different pointers that are currently touching the screen so I know what the coordinates are of these pointers using the following Code snippet case MotionEvent.ACTION MOVE Count through all the pointers currently touching the screen for(int index 0 index lt event.getPointerCount() index ) Is finger on the left button? If so, then go (or continue going) left if (event.getY(index) gt renderer.leftButton("top") amp amp event.getX(index) lt renderer.leftButton("right")) renderer.setSpritewState('l', true) renderer.setSpriteState('r', false) Or is finger on the right button? If so, then go (or continue going) right else if (event.getY(index) gt renderer.rightButton("top") amp amp event.getX(index) gt renderer.rightButton("left") amp amp event.getX(index) lt renderer.rightButton("right")) renderer.setSpriteState('l', false) renderer.setSpriteState('r', true) break However, this is constantly triggering one of the two conditions I guess as it's picking up minute movement of the finger s. And, more importantly, if there is a finger on each 'button' the sprite goes a bit crazy as each condition fights with the other and constantly flags the sprite to move left and then right etc. What I'm really after is this something like this So, if a finger moves within a specified area, nothing happens as it's counter productive. But if a finger moves from one area to another, then the action is triggered. I'm guessing the code for this would need to save the old position of each of the fingers to compare to the new positions, but I'm not really sure how to go about this. Help would be appreciated. Thanks. |
7 | Drawing and rotating bitmaps (with transparency) efficiently in Android I just started making a game for Android and I'm already having some issues regarding performance. You can imagine the game as being some kind of Tower Defense game with a top view, and the enemies can move in all directions, so I need to be able to make the sprites rotate in all directions. I'm currently using a sprite sheet with transparency for the enemies and using canvas.rotate() to make all the enemies face a given target. When there are 60 enemies on screen, it takes about 25ms to rotate and draw the enemies, but if I remove the rotation part, it takes about 7 ms. In itself, it doesn't seem too bad, but there are going to be many more enemies at once on screen eventually, with projectiles, other entities, etc. and I'm drawing the background tile by tile (around 80 tiles), so that's 80 more bitmaps to draw, although at the moment it's only 4 different bitmaps being drawn multiple times.

What's even weirder is that using RGB 565 works properly on my Galaxy Nexus, but on my friend's S3, some images (with transparency) are not displayed at all. I'm using 4.2.1 and he's on 4.1.1. So, how can I rotate my images more efficiently? Would using OpenGL improve performance a lot or would it be about the same? Is there a better solution? |
7 | Multiplatform game, save game state and resume it on other platform This is for a personal and knowledge acquiring project. I want to create a little TIC TAC TOE multiplatform game, app amp web. The choosen technology for the app will be Android or Flutter and for the web Angular. My doubt is, during a game if the user wants to change from the mobile version to the web version, how to resume or change the game to the web application? What would be the best way to save the game state and load it into the other platform? Having in consideration that the user will play only in one platform at a time, which is the best way to implement this restriction too? Is this as simple and hard at the same time as implementing all controls in both platforms and storing all the data required in the database? |
7 | Make LibGDX game responsive to different phone screen sizes? I've been experimenting with small games to learn design concepts, LibGDX, and Box2D. I am wondering how you would implement "responsiveness," so to say. For example, this is the rendering part of my game and its just drawing to coordinates. https github.com Elsealabs Stacker blob master com elsealabs stacker ScreenGame.java For example I'd like it to look good on Android phones of different resolutions or if the user resizes it on desktop. I am asking about design patterns or practices that would make this possible. Any solutions I can think of seem like they wouldn't scale or would over complicate the game. If you know of any articles or design practices that cover this topic, or have any of your own knowledge, or example LibGDX Java games, I'd love to see them. |

7 | Acceptable sound quality stereo needed for an Android game? I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re exporting it The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician composer, but he knows little about computers amp software so he just gave me some high quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same ( moving to mono), or might there be some unnoticeable differences to the human eye? |

I am really just looking for peoples experiences and personal knowledge on the subject. I am looking to create a game for both Android and iPhone platform. I know Unity is a great game engine and my question is how well does it work for creating one code base to build for both Android and iPhone platforms?

Any insite that people have on this topic would be much appreciated thanks. |
7 | Game Loop delay the right way and game speed I am a newbie game developer. I am trying to find a right way to create my game loop. Consider following example. Simple Android Game I have a game with a simple gameplay bouncing ball. I want to have a control of the ball speed. Also I want my game to have the same framerate (framespeed) on all devices. Where the speed logic should be implemented ? In my case I have simple ball object with a velocity vector. I can change the velocity vector properties in order to make my ball move faster or slower, am I right ? The Main Loop. I have read a lot of about this part of a game. I found this article http gameprogrammingpatterns.com game loop.html . And decided to use this code example double previous getCurrentTime() double lag 0.0 while (true) double current getCurrentTime() double elapsed current previous previous current lag elapsed processInput() while (lag gt MS PER UPDATE) update() lag MS PER UPDATE render() I have a lot of questions about this example. I have the similar loop in my game. Override public void run() while (mIsRunning) processGameInput() updateGameState() drawGame() I cannot understand while update() is called while waiting for a constant delay ? Why not the render method ? Maybe I am missing something. Here is how my update for the ball looks like. public void updatePosition() mCenterX mVector.x mCenterY mVector.y As you could see, each time I increase the position of the ball by the value of the velocity vector. But as can guess, in case of using the example from the article, the update method will be called for instance 100 times. And the render method only once per 100 update method calls. So in this case I guess, I the ball will be changing its position lagging. My goal is to control the speed of the ball, for example from 0.1s 2s. How can achieve this ? Please help to understand this topic. Any help would be highly appreciated. |
7 | How do I get and install the Android SDK on my Ubuntu OS? I heard that it would be a lot easier to do java type games and then move on to Android gaming? I AM a total beginning but with motive and I have been reading about it from several sources, including similar questions on this site alone. But I need to know specific things from experienced users. As for getting the SDK and Eclipse on the computer, I'm having trouble with it, I am running Ubuntu btw so exe files are useless. But I have tired terminal use but I kind of failed because I don't think the SDK and Eclipse are installed, just downloaded. Ubuntu users especially, I can use help from you seeing how complicated Ubuntu can be compared to windows "click install" setups. Also if you guys really suggest me learning Java first (which is still a big question cause I don't want to waste time with something I don't want to really use, but getting the feel of gaming is pretty important I know) I am looking at this tutorial http zetcode.com tutorials javaswingtutorial And it talks about using swing toolkit, but idk how to get that exactly, I tried searching. Sorry for the noobness, but gotta start somewhere and I'm new to this site so I'm really hoping you guys can really help me. I want to make simple games to put on the android market, and then advance. So going to the tutorial above, it just kind of starts with giving me coding and whatnot which is fine, just copy it but idk where exactly to do all this on (Swing toolkit?) so I can't even start with that. But really I want help getting this SDK and Eclipse plugins on my computer and then I can continue with this guide www.rbgrn.net content 54 getting started android game development Which is the main guide that I probably should follow, and would be great if some expert skims it a little at least to see if I should start with that guide and skip the java. But again, I'm stuck on the SDK stuff. Sorry for the long questions, I am new and I really want to get out of this beginner stage, it's the worst part. Tank you to all and if you want my facebook or AIM to help me through with IM to at least get this SDK and stuff installed fine with Ubuntu OS, ask please ( |

7 | Why does my game freeze when I try and display a menu? I make a MenuScene when my Game loads, which grabs some intro text from levelData and displays it and a button to start playing the level. When the MenuScene is created and displayed in onLoadComplete() it's fine. However when I display it again when advancing the level (levelData is loaded with new data and the MenuScene reset) it freezes, showing the game at the point the level was beaten. The menu is not displayed at all. I'm just calling loadIntro() this.mScene.setChildScene(this.mIntroScene, false, true, true) this.mEngine.stop() to display the MenuScene (the same both times, it works the first time but not the second), where loadIntro() is private void loadIntro() this.mIntroScene new MenuScene(this.mCamera) final TextMenuItem intro new TextMenuItem( 1, mFont, levelData.getIntroText()) intro.setBlendFunction(GL10.GL SRC ALPHA, GL10.GL ONE MINUS SRC ALPHA) intro.setSize(400, 150) this.mIntroScene.addMenuItem(intro) final SpriteMenuItem startMenuItem new SpriteMenuItem(MENU START, this.mMenuStartTextureRegion) startMenuItem.setBlendFunction(GL10.GL SRC ALPHA, GL10.GL ONE MINUS SRC ALPHA) this.mIntroScene.addMenuItem(startMenuItem) this.mIntroScene.buildAnimations() this.mIntroScene.setBackgroundEnabled(false) this.mIntroScene.setOnMenuItemClickListener(this) What am I doing wrong? |
7 | How do I handle user input with good class structure architecture for an Android game? How do I handle user input having quot good quot class structure and following normal game architecture ?(see below). At first I didn't think this question was Android specific, although, after seeing a great response in C I would appreciate some insight on this question using Android architecture. Current way I handle input for my Android Game Created controller class that takes X,Y screen events and X,Y character position and returns an int that represents a direction the character should move. Call the controller method in the game's update. Send that direction value to my character update. Character's update calls move (which is also passed this value). Basic switch statement determines the direction my character moves. Getters and setters for the position of the character.(should I have them for this direction also) Is there a better way of handling input? This doesn't feel like the best way. Where does input fit in with class structure and game architecture? I'm going to accept the C answer but I would really like to see a Java answer for Android in the future. D |

7 | Make a 2D character stop moving and going back when encounter an obstacle I am using a 2d character who is sliding infinite ( huge incrementation of the X or Y value ) when moving. He can only move up, down, left, right inside a virtual grid, made of multiple squares. Now I want to add obstacle to stop his sliding and make him go back to the center of the previous square The obstacles can be of different size and are located in the center of a square, so the collision occurs with the obstacle and NOT when the character enter the square containing this object ! How can I manage to stop the incrementation of X or Y when colliding ? And get the previous value of X or Y for which the character was on the center of the square just before the one containing the obstacle. Thank you everybody ! I am not certain to have the good reasoning. Actually I was thinking about something like that Lets say each square is 5 5 and each square center is at X 5 from the previous square center and X 5 from the next. I was thinking about a loop which is moving the character from 5 on the X axis and checking if there is a collision. If yes, the character goes back to the previous square center, if not, the loop keep going. So assuming that my character is in ( 0 0 ) coordinates and the obstacle is in ( 20 0 ) coordinates ( but not filling the square ), my character will be in ( 5 0), then ( 10 0 ), then ( 15 0 ), then it will collide with the object in ( 18 0 ) ( because the object dont match exactly with the square size, considering the fact that on object can be 3 3 and just drop on a 5 5 square ), and the character will go back to ( 15 0 ). With this reasoning is the movement of my character going to be smooth ( like a slide ) or is it going to be square by square ? if checking the collision BEFORE moving, is my character going to move from ( 15 0 ) to ( 18 0 ) and bounce back to ( 15 0 ) or is it just going to stay in ( 15 0 ) ? because I would like to have my character to move smoothly AND bouncing back when colliding ! Thank you |
7 | Android Synchronizing timers across multiple devices Im writing a turn based multiplayer game that implements a chess timer. When the current players turn starts, all devices start timing for the current player, however, as his turn proceeds, the timers fall out of sync, and at the end of his turn(say for example he took 1 minute to make a move) his time on the other players devices are sometimes up to 10 seconds ahead or behind. I understand theoretically its impossible to time sync devices down to the millisecond, but if i can get it atleast within a second, that will work just fine. I tried the following the try overcome this Sync time across devices at the beginning and end of current players turn. Sync time whilst it is current players turn. Combination of the two. The problem with these attempts is that they cause a lot of flickering on the clock, and, at the end of the turn, when other players see the current players time increasing by 5 10 secs, they feel cheated, and it just doesnt look good. Newbie here so be gentle with your responses ) |

7 | How do I implement tilt controls that work even when the device is not vertical? I'm using libGDX to develop an Android game. The main character can be moved freely in the 2d plane by tilting the phone. The relevant part of my current implementation looks somewhat like this Vector2 mainCharacter float speedX, speedY public void render(float delta) speedX 0.6f speedX 0.4f Gdx.input.getAccelerometerX() speedY 0.6f speedY 0.4f Gdx.input.getAccelerometerY() mainCharacter.move(speedX, speedY) This simple implementation works quite well as long as the player sits or stands upright. But there are two situations where this approach fails If the player holds his phone almost horizontally (e.g. if he lies in bed, see fig. 1). Neither the computation of speedY nor the computation of speedX works properly in that situation. Inside a moving vehicle. When the vehicle speeds up or slows down, this has a strong impact on the values returned by Gdx.input.getAccelerometerX Y. So my question is Is there anything that can be done to solve these two problems? How can I get satisfying results independent of whether the player is lying, standing or sitting? And is there a reasonable way to reduce the influence that the movement of a vehicle has on the output of the accelerometer? fig. 1 |
7 | Libgdx Hud with two stages I have an app that's currently working with a single stage but i need to add a side display section as a HUD, with scores lives etc on it, so that the HUD is on the left, and the main hand screen on the right. The main game screen will be fixed and will not move around. From researching I've found a couple of solutions. 1 two stages 2 a group with two groups to it, possibly using a horizontalgroup 3 two cameras one stage 4 one stage, one camera, but changing the position of the camera for each set of actors. I think, option 1 is my preference, but i have some questions. Do stages always fill the whole screen, or can i start then where i want? This would make it easier for the right hand screen to calculate positions based on 0,0 of that screen rather than always having to add the width of the HUD on to any calculations. Do i need to work about viewports? Currently I'm not using one (which i think means my stage is set to scaling by default) but nothing looks stretched as a result of this. I don't know much about viewports, but there always seems to be a compromise to be made with them, i.e. black bars top or sides. If I have two stages, do they each have their own camera? Do I need to with about this? Can I possibly aim the right hand camera at an offset so i can still draw things from 0,0 with that being the bottom left corner of the right stage, not the whole screen? Finally, off topic, I am a little confused about spritebatch. I'm not currently using one, because I use a stage. Is that OK, or should i still be using one in conjunction with a stage somehow? And add all my actors to that? |
7 | Sign APK of several games with same or different key? When you choose a key for signing your APK for publishing in GooglePlay, you need to care of this key for the next 25 years if you want to do updates. The key should not be shared with anyone. The key should not be lost. If you do several games, you face the question of having your key DeveloperName and sign all games with it, or have multiple keys like DeveloperName GameOne for one game, DeveloperName GameTwo for another, and so on. Google says here http developer.android.com intl es tools publishing app signing.html that if you sign several APPs with the same key, they may talk to each other. So it seems that having all with one key will allow future interoperability between games easier. Instead, if at some point someone wants to buy you one of your games, but not the other, you don't want to give the keys to the non sold games but still you don't want the buyer to break the update flow. So it seems that having each game with a different key is better. Question 1 What exact benefeits will one have if one signs 2 games with the same key? Is that necessary? Is that worth for future interop between games? Question 2 What is the correct practice for an indie doing several games regarding the signature of them? |
7 | Keeping track of onscreen objects in opengl es on Android In a small game Im working on I was able to implement ray picking with an opensource 3d engine called min3d but I cant figure how to keep track of what object is onscreen. I will some times have upwards of 120 objects to render within my scene and the raypicking is off occasionally. What id like to do is keep track of how many screen objects are within the camera and being rendered onscreen and set a boolean value based on that to add or remove objects from my arraylist I iterate through when the screen touch is registered and the ray picking method goes off. So how can I check for which objects are onscreen and offscreen in opengl es on android. |

7 | Advantages and disadvantages of libgdx I've been an android developer for a while and am thinking about getting into gaming. While looking for a game dev framework, I thought libgdx provides very friendly documentation and functionality. So I would like to use it if there is no big obstacle. But when I tried to see how many developers employ this library, I could find not that many. Is there anything wrong with this library? In other words, I would like to know its advantages or disadvantages from any experienced developer. UPDATE After reviewing its documentations and trying to build simple games with libgdx, I decided to go with it as its documentations are good enough and its community is very active. What I liked the most is that it provides a bunch of demo games that I can learn a lot from. |

7 | What Type of Options should be on the Game Settings Menu? I have seen a post about the main menu options here UI Main Menu options for mobile games. What options should be listed? What do users want to see? But I want to know what kind of options should need to be available on the settings screen. I am making a rather simple 2D game for Android, but really I haven't found many aspects that warrant an options button or a check box besides turning the sound and music on off. I was thinking graphics settings but then again, how many apps really need graphics settings besides immersive 3D ones? |

7 | AndEngine Box2d game I'm developing a 2d survival shooter using Box2d extension and I've got some questions I have two AnalogOnScreenControls. Their listeners modify both sprites and bodies. I receive TouchEventPool was exhausted and as their number grows the game crashes accidently. I've tried to put the modification of the bodies and sprites on the UpdateThread but that does not solve the problem. What could be the cause? I have a class that at the beginnig of the game loads all the textures. After I relaunch the game activity several times I receive Unable to find Phys Addr for and "green color" interface. But that doesn't happen if I clear the memory manually through the Task Manager before relaunch What could be the cause? I unload my atlas at the end of the game. The game sometimes crashes at start with NullPointerException in onResumeGame. The solution suggested is to set android configChanges "orientation screenSize" but my device is API 10 so it doesn't have screenSize property and orientation only does not seem to help, because the game starts in portrait mode at times (though landscape is set in the code) |
7 | How should I store a Game Database on Android? I'm looking at creating a game for Android and while I have most of the ins and outs worked out, the one thing I'm struggling with is how to store data for the game. Ultimately, the game will be based off of a lot of pre defined data and statistics so the obvious choice to me would be something like SQLite, but as I'm pretty new to the realm of Android and Game Development, I'm not 100 certain if this is the right route to follow. The data will be general pre defined data as well as player data (along the lines of careers stats what place finished, etc). I was wondering if there was a better best practice solution that wasn't SQLite and that would provide said functionality and if so, could you point me in the right direction? |

7 | Technique to have screen independent grid based puzzle with sprite animation let's say I have a fixed size grid puzzle game (8 x 10). I will be using sprites animation, when the "pieces" in the puzzle is moving from one grid to another grid. I was wondering, what is the technique to have this game being implemented as screen resolution independent. Here is what I plan to do. 1) The data structure coordinate will be represented using double, with 1.0 as max value. Puzzle grid of 8 x 10 Environment double width 0.8 double height 1.0 Location of Sprite at coordinate (1, 1) Sprite double posX 0.1 double posY 0.1 double width 0.1 double height 0.1 scale PYSICAL SCREEN SIZE drawBitmap ( sprite image, sprite image rect, new Rect(sprite.posX Scale, sprite.posY Scale, (sprite.posX sprite.width) Scale, (sprite.posY sprite.Height) Scale), paint ) 2) A large size sprite image will be used (128x128). As sprite image shall look fine if we scale from large size down to small size, but not vice versa. Besides the above mentioned technique, is there any other consideration I had missed out? |

Since I removed the log in a previous edit I will just say i'm looking for feedback on compiling shaders. Solution More questions Ok, the problem seems to be that either ints are not working(generally speaking) or that you can't mix floats with ints. That brings to me the question, why on earth glGetShaderInfoLog is returning nothing? Shouldn't it tell me something is wrong on those lines? It surely does when I misspell something. I solved by turning everything into floats, but If someone can add some light into this, It would be appreciated. Thanks. |
7 | AndEngine drawing 2D tiled game field I'm in process of developing simple android puzzle game. I decided to choose andEngine as an engine for my game. In my game I have a gameField array, which represents a game field, where each element is a cell of game level and consists of a type of the cell (for ex. FLOOR of WALL). During the game, state of cell can be changed (for ex. DOOR CLOSED changed to DOOR OPENED), but it happens rarely, almost all the elements of gameField don't change. I tried to implement that by adding repaint method to updateHandler, which would paint sprites for each cell every tick. But I wonder wouldn't be that approach a wasting of memory and processor time? What is the best practise for doing that? |
7 | How do I "reset" the color in OpenGl ES 1.0 1.1? In my 2D game I use glColor4f() to set the color and draw my screen border rectangles but when I try to start drawing my game objects, made up of a texture on a rectangular "quad", using GL10.GL TEXTURE 2D, GL10.GL VERTEX ARRAY and GL10.GL TEXTURE COORD ARRAY no GL10.GL COLOR ARRAY, it uses the "current color" from glColor4f(). My question is what do I need to set reset in OpenGl ES to re enable it to use the colors from the texture when I try to draw them? If I comment out the border drawing, so glColor4f() never gets called, the colors are fine. I'm not using double buffering. I read that once you set the color with glColor4f() it stays set, unless you possibly use glPushAttrib(GL CURRENT BIT), but I heard that that's expensive, time wise. |
7 | How can I refer to Android assets in other directories? My project was initially not meant for Android, and its assets are organised along the following directory structure (I hope the ASCII art renders reasonably well) engine src enginefile1.cpp ... textures texture1.tex ... game src gamefile1.cpp ... textures gametexture1.tex ... ios various iOS specific files android build.xml AndroidManifest.xml jni Android.mk assets other Android specific files othergame My game android jni directory is almost empty because Android.mk points to the relative paths of the source files in engine src and game src. Actually, it even includes the proper Makefiles so that I never have to modify Android.mk when I add or remove a source file to the project. Both engine and game provide assets that need to be shipped with the Android build. I would like build.xml to refer to these assets without having to manually copy them. A rule that copies the assets at build time then deletes them would be acceptable, but of course I would prefer a zero copy solution. Does this make sense? How did others solve this cross platform build problem? |
7 | How do I create an in app update for a mobile game? I'm researching how to make an in app update on mobile game. When there is a hotfix, or an update, I don't want users to have to go to Play store, or App Store to update, but rather for them to update inside the game (like in Clash of Clans). I want to do this because Apple takes too much time for reviewing. I found https ionic.io, they use Cordova to embebed HTML inside. We can do live update, rollback to old version with a click. This is pretty suitable for normal app, but for game, the performance is not great. How can I create an in app update like this? |

7 | LibGDX Android Textures reload other textures, and transparent images get black backgrounds Pictures I have very strange problems with my LibGDX Game in Android The problem is that sometimes the textures get black backgrounds when they should be transparent, and sometimes when I remove the texture, or press the back button, the textures get replaced with other textures that I have. To clarify I'm using x texture to show the status of health. I'm using three x textures to show how many lives the player got, and when I lose health, and remove one texture, the x texture get replaced with y or z texture, or the remaining x textures get black backgrounds. Sometimes it works flawlessly, and the x texture gets removed, and the backgrounds are still transparent. I'm loading my textures via an AssetManager, and just load them on create(). In my render I use this Gdx.gl.glClearColor(1, 1, 1, 1) Gdx.gl.glClear(GL20.GL COLOR BUFFER BIT) Gdx.gl.glBlendFunc(GL20.GL SRC ALPHA, GL20.GL ONE MINUS SRC ALPHA) batch.enableBlending() batch.begin() for (Entity life LifeEntities) life.render(batch) batch.end() I'm also using this in my Launcher Class. AndroidApplicationConfiguration cfg new AndroidApplicationConfiguration() cfg.r cfg.g cfg.b cfg.a 8 MainGame myGame new MainGame(arrayName) initialize(myGame, cfg) I do dispose the textures also. I have looked up on google and on gamedev about this problem, but all the questions are for problems when the transparent always have black background, not when it is something that happens like a bug. Any suggestions on where the problem could be? Thanks a lot, if you need more code, please let me know. Pictures of the problem |
7 | Android Swipe In Unity 3D World with AR I am working on an AR application using Unity3D and the Vuforia SDK for Android. The way the application works is a when the designated image(a frame marker in our case) is recognized by the camera, a 3D island is rendered at that spot. Currently I am able to detect when which objects are touched on the model by raycasting. I also am able to successfully detect a swipe using this code if (Input.touchCount gt 0) Touch touch Input.touches 0 switch (touch.phase) case TouchPhase.Began couldBeSwipe true startPos touch.position startTime Time.time break case TouchPhase.Moved if (Mathf.Abs(touch.position.y startPos.y) gt comfortZoneY) couldBeSwipe false track points here for raycast if it is swipe break case TouchPhase.Stationary couldBeSwipe false break case TouchPhase.Ended float swipeTime Time.time startTime float swipeDist (touch.position startPos).magnitude if (couldBeSwipe amp amp (swipeTime lt maxSwipeTime) amp amp (swipeDist gt minSwipeDist)) It's a swiiiiiiiiiiiipe! float swipeDirection Mathf.Sign(touch.position.y startPos.y) Do something here in reaction to the swipe. swipeCounter.IncrementCounter() break touchInfo.SetTouchInfo (Time.time startTime,(touch.position startPos).magnitude,Mathf.Abs (touch.position.y startPos.y)) Thanks to andeeeee for the logic. But I want to have some interaction in the 3D world based on the swipe on the screen. I.E. If the user swipes over unoccluded enemies, they die. My first thought was to track all the points in the moved TouchPhase, and then if it is a swipe raycast into all those points and kill any enemy that is hit. Is there a better way to do this? What is the best approach? Thanks for the help! |

7 | How should I control leveling up in a knowledge skill testing game? I have developed a game that tests the knowledge and skills in a series of short quiz like games. Players have to move from Level 1 to Level 16 (with Level 4, 8 and 12 as major milestones BANDS). The Difficulty level of game questions increases at each level. The level progression is currently based on 'POINTS'. Points in turn are based on Correct responses, faster responses, Wins, Completion etc. Points continue to increase for a user irrespective of Win Loss (the duration of completing the levels varies) The challenge I foresee is 'every user can progress to Level 16' if he keeps on playing the game long enough (irrespective of whether he has acquired the skill knowledge for the next level). I am looking for a simple to understand progression rule(s) that would make lower skilled players remain longer in that BAND before progressing to the next level and BAND. What are some best practices in Level progression that I can refer to for overcoming this issue. Thanks, |
