0 | In Unity, how do I add a MeshFilter to an empty GameObject to generate a procedural model? My code below is modeled after Unity's documentation. When I put the script into an empty GameObject, the error I get is MissingComponentException There is no 'MeshFilter' attached to the "myMesh" game object, but a script is trying to access it. How do I add a MeshFilter (and the other necessary Components) to the empty GameObject in order to generate the model procedurally? using System.Collections using System.Collections.Generic using UnityEngine public class myMesh MonoBehaviour public Mesh mesh void Start() mesh new Mesh() GetComponent lt MeshFilter gt ().mesh mesh |

0 | Find alternate shortest paths in Unity I'm developing a game in Unity. It's a simple game where the rocket has to reach the point where the player touches on the screen. The movement of the rocket is physics based. When the rocket goes off screen on right side, it appears on left side and when it goes off on left side, it appears on right side. Similar for vertical axis. In the picture above, the user touches on the bottom right corner. The rocket could either rotate and go there (Path 1) or it would directly go up left off the screen and appear on bottom right corner and reach there(Path 2). I want to implement the Path 2. How would it calculate the distances and determine the shorter path and then proceed in that direction? |
0 | After baking my lights again in Unity, my character is black? I had to re bake my scene several times before getting the look that I wanted. This last time, the scene looks great, but my characters are now very dark and the playable character is completely black. He lights up only when the directional light hits him. Saying this makes me realize the problem (sort of) All the spotlights from the room's interior were probably baked while the characters were turned off, making their solution require the only real time light in the scene in order to be seen. Still, I didn't think the characters would be involved in the lightmap data? How do I redo the lights just for characters and moving objects? How can I fix this and keep the scene lighting? |
0 | Draco encoder lossless, is it possible? I'm trying to use the draco library in a Unity project. I've a lot of obj files with models of a person in different positions. When I encode these models with the draco encoder command I obtain a lossy conversion, and a lot of parts of my original models get lost. I tried to play around the parameters qp and cl in order to change the quantization and the compression level, but also with qp at its maximum and cl to its minimum some parts get lost. In this image the left model is the original one. The right model is the one converted with draco encoder by using cl 0 and qp 21. As you can see some parts are missing. Do you have any suggestion on how can I obtain a lossless (as lossless as possible) conversion? |
0 | How can I reduce the performance impact of rendering trees? I'm making a low poly stylized kind of game. I have a terrain with some water, and I want lots and lots of trees I have 10,000 trees mass placed, at the moment. Each tree consists no more than 200 triangles, so they aren't too taxing. The main problem is, there are lakes, and the lakes are quite large. You can't actually see any trees on the other side of the lake, and that looks really bad, especially when you walk there and trees suddenly appear. To fix this, I have to increase the tree distance so that you can see a decent amount of trees on the other side of the lake, but that reduces performance to 40 50fps, and there is hardly anything else in the game yet. I'm using a GTX 1080, if that helps. What can I do to make my game run faster with more trees? |
0 | Updating object's property on Start is visible for a second when game loads I have a world selection scene in which I have GameObjects representing worlds. The GameObjects have default properties when the scene is loaded. For example the world name text is red and each world has a "locked" status. This initial state can be seen in the following screenshot On the Start() method I'm dynamically updating the properties on each GameObject based on values I'm reading from a save file. If a world is unlocked the name text is set to white. If a world is currently selected the name text is set to green. Here's what that looks like at run time The problem is that when the scene is loaded from another scene(e.g. by clicking a navigation button) the initial state of the GameObjects can be seen for a second and then they change to the proper values as dictated by the save file. How can I prevent this from happening? I was under the impression that anything that happens in the Start() method takes place before GameObjects are rendered. Here's some slimmed down code of what my code looks like var worldIcons FindObjectsOfType lt WorldIcon gt ().OrderBy(x gt x.WorldNumber).ToList() var saveFile GameSaveManager.GetSaveFile() if (saveFile null) Debug.LogError("Could not find save file while loading worlds") return foreach (var worldIcon in worldIcons) var savedWorld saveFile.Worlds.SingleOrDefault(x gt x.Number worldIcon.WorldNumber) if (savedWorld null) add world to save file GameSaveManager.CreateWorld(worldIcon.Controller) unlock first world by default if (saveFile.Worlds.Count 0 amp amp worldIcon.WorldNumber 1) worldIcon.Unlocked LevelMapController.LockedStatus.Unlocked.ToString() else worldIcon.DisplayName savedWorld.Name worldIcon.WorldNumber savedWorld.Number var button worldIcon.GetComponent lt Button gt () if (savedWorld.Unlocked) button.interactable true button.targetGraphic.color Color.white worldIcon.Unlocked LevelMapController.LockedStatus.Unlocked.ToString() else worldIcon.Unlocked LevelMapController.LockedStatus.Locked.ToString() |

0 | Prevent showing movie files after packaging unreal game I developed a game which has some videos inside it. I added videos into my project folder so that I can access them. After packaging, on the folder all videos will be shown as its original format which everyone can play it. How is it possible on release version no one can go to game folder and play it? Maybe some kind of encryption or change format of file which only its game can play it would help it. For example when you have a game on your computer, the only way to see the video is that you play the game and you will see relevant videos in the right time. However, after packaging, all videos will be on a folder any everyone can go to the folder and play it and see videos even without playing game. In Unity after releasing the game, you can't access assets, it will be shown in a file with .resource extension so no one can access it. However, in Unreal Engine, it will show the real file. |

0 | Trouble with assigning a model's own mesh to a mesh collider in Unity I'm trying to use a mesh collider on the player's avatar, rather than the box collider. I've added the mesh collider to the game object (which also has a rigid body) and selected the "convex" checkbox. However, the player still falls through all geometry, including Unity primitives, terrain, and other models. In the mesh collider's property box, there's a value for "Mesh", which I have set to "None (Mesh)". I was led to believe this defaults to the model's own mesh, but now I'm not certain. If I change the value to something else from the "select mesh" list, like the cube, the collisions work. When I click over to Select Mesh Scene, the list is empty. I'm assuming I need to add the model's mesh to the list, but I can't find any documentation about that. |
0 | Tile draws pixels from adjacent tiles Whenever I try to draw from the tile palette, this is the result. why does this happen?

0 | Billboard rendering without distortion? I use the standard approach to billboarding within Unity that is OK, but not ideal transform.LookAt(camera) The problem is that this introduces distortion toward the edges of the viewport, especially as the field of view angle grows larger. This is unlike the perfect billboarding you'd see in eg. Doom when seeing an enemy from any angle and irrespective of where they are located in screen space. Obviously, there are ways to blit an image directly to the viewport, centred around a single vertex, but I'm not hot on shaders. Does anyone have any samples of this approach (GLSL if possible), or any suggestions as to why it isn't typically done this way (vs. the aforementioned quad transformation method)? EDIT I was confused, thanks Nathan for the heads up. Of course, Causing the quads to look at the camera does not cause them to be parallel to the view plane which is what I need. |
0 | ECS Stats, damage types damage calculation Prologue Im quite new to data oriented programming and my goal is to implement a runescape stats damage mechanic. This is quite a pretty complex topic Runescape Mechanics 1 and i havent found any ECS related sources on that topic yet. In the following example we see a bunch of items which modify the weares stats based on a few conditions. This happens in two different variants, either for the damage calculation only, or as a buff. Brine sabre and Brackish blade increase damage against crabs. or Silverlight and Darklight increase ability damage by a scaling of 25 124 against most demons. The exact damage bonus is based on your base Attack and Strength, and the monster's base Defence. The problem Such a RPG system is very complex. There different damage types, different resistences and other stats. Having a strong OOP background and no real experience in DOP, i cant find a suitable architecture to fill those needs. In my current approach every stat is a component. Items and Buffs are structs. A item quot buffs quot its owner and the buff modifies his stats. This works so far, but i have no idea how i could realise the damage calculation, while still keeping it that flexible as it is in runescape. This little example would just be able to buff the stats... not deal, receive or modify the damage itself. The stats public struct Health float max float value public struct MeeleDamage float base float value public struct MeeleResistence float base float value Item amp Buffs public struct Item string name int amount bool equipable List lt Buff gt buffs public struct Buff string name float duration Condition applyable ToBuff stat float value Its also important that an entity can also deal damage to multiple other entities in one frame. How would you implement such an complex mechanic ? Any examples are appreciated ! |
0 | Generating mesh along path I'm currently trying to generate a path along an array of points (Vector3) This is the result I'm currently getting The dark gray points are the given path The red points are the generated vertices And the triangles are obviously the mesh I failed to generate correctly And from the bottom it looks like this, which is odd, because I'd expect all the missing triangles to be at the bottom.

0 | What would be the best way to find a Game Object that is closest to another Game Object in unity? I made a 2d space shooter game awhile ago and I want to go back into it and overhaul some things. I'll provide a link to the game so anyone can play and get a better understanding of what I'm trying to do. https your pal drewdle.itch.io starspeed With how the game is currently set up, all the enemies are constantly setting their rotation to be facing the position of the player. I want to go back in and add a co op mode where there are 2 players, however, if I just added a second player without changing any code, the enemies would always be facing Player 1, never directly facing Player 2. I was thinking that I could get around this by giving each enemy an invisible circle with the center at the enemies position that would constantly expand until it hit one of the two players, I could then set the enemies rotation to face the point where the circle collides with one of the players. In theory, this would make it so that each enemy is facing towards whichever player is closest to it. So my question is How could I go about implementing this in unity? Or, is there a better or more efficient way to do this that would yield the same result? I've spent a decent amount of time researching this and I haven't had much luck. All help is appreciated, if you need more explanation just let me know and I will do my best to explain in more detail. |
0 | How can I set up potentially dozens of cameras rendering to targets without killing performance? I'm thinking through how I'd do a particular trick for playing cards with animated 3D faces. Setting up a single card is pretty trivial. I would create another camera somewhere, maybe restrict some layers so it'll only show what I want it to show so I don't have to worry what's behind it, put an object in front of it that is the basis of the card, have the camera render to a texture, and put that texture on a quad (the card) with the same aspect ratio. Now whenever the main camera views the card, regardless of angle, the card displays what the other camera sees. I don't believe this approach would scale well as I'd have to duplicate everything for every card. The way I imagine it, there could be dozens of cards visible at once so every frame would require rending all of them. Even at low qualities that sounds bad for performance. Also the main reason I want to animate cards is to have them respond to input and actions happening to the cards so two instances of the same card won't show exactly the same thing. Another thing is where would I place all these cameras and their models in the 3D space so that they won't see each other? I could put them on top of each other and use layers to only capture what I want but something doesn't feel right about having dozens of layers. How would I begin to pull this off on a scale of dozens of cards? |
0 | Calculate a random position inside a 2D area excluding a subset Given this area X X X X I have a GameObject size 4x4 and inside another GameObject size 2x2.

What I am using right now is Calculate position inside 4x4. If that position is inside 2x2 go back to step 1. But it is not a good way to do this. Do you know can I calculate a random position inside 4x4 area evading a 2x2 area? I though generating small GameObjects, 1x1 instead if 4x4. So first select a random of the 4x4 tagged, for examble, as "IsWalkable", and then calculate a random position insided the selected small square. |

0 | Best way to connect multiplayer users with each other (matchmaking) on a low powered server? OK so I am using unity to make a multiplayer game, but I'm not sure how to connect players with each other over the internet. Unlike other questions, this isn't a general problem of working out how to do UPnp or using unity's matchmaking server. My issue is that my server that I would use is a simple low powered pc (running normal windows 10, no idea how to use windows server). I think it is powerful enough to match players with each other, but not to host more than one or two actual games. The other issue is that I have a residential internet connection with a dynamic ip that changes every few months. However the speed should be ok (150Mb s download, 20Mb s download). Also, I'm not planning to spend money on a monthly basis for a server (like unity's matchmaking service) as I plan to spend as little as possible (So far I've paid 12 to Microsoft for a dev account and I've received a 200 voucher from them so my current spending is 189!) So my question is should I use my server (would it work), are there any online services that are very cheap to use, or is there another way to make this work? Only other thing is I could use the free 20 users at once on unity's matchmaking, but would this limit be too small? EDIT just for information, my game is a simple tank shooter. I was thinking about limiting the amount of tanks in a game somewhere around 8 20. The bullets in my game are physical objects with rigidbodys and they move at a slower speed (if you've ever played tank trouble, it looks like that). The world is in 3D. There is a potential for there to be up to a hundred bullets in a scene at once at the worst. After hosting a LAN world with 7 players connected for about 20 30 minutes, windows reports the data usage being around 3 4MB. |

0 | How to Change position rotation of a parent while keeping X and Z Rotation Sooo this question is a problem , a evolution by another solution of this problem here How can I change the parents rotation so the childs rotation is looking at a specific direction Basically We have a "Eye" (HTC Vive). We have a "Parent" which is the Parent of "Eye". We can not change the position or rotation of the Eye in code. We can only change the position and rotation of the Parent. 1.We want to modify the Parent Position so that Eye to goes to a certain "Target 1" position. 2.We want to modify the Parent Y Rotation so that the Eye looks at a certain "Target 2" position. 3.While doing this we dont want to modify the Parent X or Z , because this would lead to a Rotated game experience. The Parent Position changes so the Eye gets to "Target 1" position. The Parent Position changes so Y Rotation should look at Target 2 position The Parent X Z Rotation should not modify the Eye X Z |
0 | Switching from software Engineer to Game developer I don't know if this is the right place to ask this. I've been working as a software engineer for 3.5 years so far, mostly web apps, mobile apps, web pages in banking systems, educational, etc but I always wanted to work as a game developer. Currently I have a university degree in CS, and I'm attending a masters degree in Apps design. I've very little experience in game dev (only for hobby), some space shooters and some steps in unity, also I took some courses of blender, and did some simple sprites (those 8 bit characters but animate them is a big problem for me atm.) but I've never gone too far. I know I cannot focus on all aspects of game development, because it is a huge world integrated with different disciplines, but I need to make a portfolio with some of my games at least. (I only have partial prototypes, some of them work, some don't...) I need some advise of people who are in the game business. Which platform framework do you recommend for me ? I already know a bit of Unity and I feel pretty comfortable with it. I can get some assets to work with (models audio, etc), there are some free material in the store, and I have budget to spend on that too if necessary. How do game companies hire people? What am I suppose to aim for a job? I mean this is a world full of disciplines and I need to focus in something particular I guess, I'm a senior frontend developer too, so I guess I should focus on coding. I think portfolio is the best way of showing your work. Any suggestions are welcome! thanks! |

0 | Unity Tilemaps Best practices I'm pretty new to Unity and I just finished some courses and tutorial found in the official documentation. I'm now in the process to apply what I learned so far using different assets from the ones provided with the tutorial, to see if I understood all the material. I'm trying to build a simple top down game with some free asset I found online. My tile palette is composed, among others, of tiles like these Now, in order to create something like this sorry for the quality, I recreated it in gimp since I'm not on the computer where I have Unity now I had to create three Tilemaps under the same Grid. The botton tilemap contains the grass (sort order 2), the middle one contains the fence (sort order 1) and the top one contains the house (sort order 0). My first question is given the tileset I have, is this the most efficient way to obtain what I needed? After having solved this problem I wanted to add a collider to the fence and to the house, but since they are on two different tilemaps I cannot use a composite collider to optimize the collider's layout. Is there another way to do this in a more efficient way? Instead of using tiles for quot interactable objects quot , should I use quot proper quot game objects instead? |
0 | How to make an authoritative multiplayer game deterministic for all clients? I'm starting to create a multiplayer online game, with an authoritative server. As it is, the clients send inputs to the server which do the simulation and then send back to clients the updated state. The game is a top down shooter, so it's fast paced and input lags are not allowed here, so to avoid this I'm doing the simulation on the client too, and when the server update come back I compare the local simulation with the server response. If they are compatible everything is fine, otherwise, the client version is corrected. I was expecting that the client simulation desync at some point, because of all of the variables on physics, floating points, network etc... But this happens much more than I thought. Just by sending the inputs and simulating on the server, the results are very different, even on simple movements, like forwards and backwards on a clear space. Green is local, red is server response I need help on this step, a way of keeping, at least this kind of simple movement, consistent on the server and the clients. |

0 | How can I prioritize the call order of decoupled scripts? I have a player with many individual components that each handle a behavior such as jump, block, attack, duck, etc.. None of the scripts know about one another. Each listens for a specific input to fire. Some behaviors share the same input depending on the characters state such as ok the ground, in the air. I'm running into issue where the wrong behavior will fire that has shared input (down attack instead of down attack being held down for x seconds). I'm looking for advice on how to manage these behaviors and have more control over what can happen when. I've tried resolving this issue by creating a method that will disable other behaviors temporarily while completing the action and I've changed the script execution order. I thought about adding a discrete player state and restricting what behaviors are able to be performed at any given time but this increases the complexity quiet a bit. |

0 | Problem with grid generation in Unity 5.1 Using Unity 5.1 and was following a tutorial for generating a grid for a Minesweeper style game. Link to the tutorial for reference http gamedevelopment.tutsplus.com tutorials build a grid based puzzle game like minesweeper in unity setup cms 21361 Tutorial is Unity 4, but I don't think it should matter. Here's my code public GameObject tilePrefab public int numOfTiles 10 public float distanceBetweenTiles 1f void Start () CreateTiles() void CreateTiles () float xOffset 0f for (int tilesCreated 0 tilesCreated lt numOfTiles tilesCreated ) Vector3 positionVar new Vector3(transform.position.x xOffset, transform.position.y, transform.position.z) xOffset distanceBetweenTiles Instantiate(tilePrefab, positionVar, transform.rotation) Essentially, the problem is that when I coded the spacing algorithm, Unity decided to ignore the spacing of 1f, but instead do 10,000. No matter the number I substitute for "distanceBetweenTiles", Unity spaces the cubes by 10,000 points. I'm assuming it has to do with how Unity is handling the float numbers, but I'm not quite sure, considering the number I substitute doesn't seem to matter. I've included a screenshot of Unity running the script and the inspector view of the giant X position. Thanks so much in advance 1 |

0 | unity and maya how to export import fbx animation with rootmotion and non rootmotion clips? I've started learning about and playing around with animations in Unity and I've installed the Basic Motions Pack by Kevin Iglesias. I wanted to know how they work and to see if I can modify them so I've looked at the animation files which are .fbx. The animation hierarchy in Unity looks like this where BasicMotions Walk01 is the in place animation and RootMotion is the root motion variant which has velocity. I've looked into what root motions are and I think I've grasped what they are, but here's where things have gotten interesting. I've imported the BasicMotions Walk01.fbx into Maya and it looks like this it has a root joint for root motion and the animation moves the rig in each keyframe. So far so good! I've modified the animation so that it plays in reverse, basically made a sketchy reverse walk animation. Exported it to .fbx with the following parameters And then opened that in Unity, however when I import the animation and rig it it only has one clip and it's the Root motion clip, and I can't get the non rootmotion clip. The Root Transform Position (XZ) Loop match is always red and if I don't bake it into pose the animation functions like the Kevin's RootMotion animations, but I don't know how to get the non RootMotion clip. What am I doing wrong here? |

0 | Unity job system long running task I have a long running task (250ms )that I want to pick up a resultant array from. This job is a path finding service that should run periodically in the background. It's all prototyped in another language using a background Thread. According to the Unity docs, I should call Complete() when I'm ready for the results of this job. However, I don't know when this task will complete I don't want my main thread to wait on this job completing. I want this job to run async and to collect the result from a Nativearray the resultant search array null (if it's a first run and still in process. with concurrent array access protected by a lock. If the job is writing to the array, it should be locked. What's confusing is that most of the Unity job examples seem to use short jobs that last a few frames, then pick up a result in a LateUpdate() or next Update(). My job is much longer running. Since my job uses no Unity API directly, am I correct that standard c Threads seem more applicable for my kind of problem? |
0 | Manual response when 2 shapes made of rectangular volumes collide I have 2 compound objects made of rectangular blocks. One of them (the one that is moving) has a script that listens to OnTrigger callbacks. What I need is to position the moving compound object on the first compound object to make then not collide but stay in contact. As an example you can thing of two "spheres" made of blocks. Both spheres are on the floor. Then I move one of the spheres (still on the floor) and I detect that it collides the other sphere, so, I need to push the moving sphere up to make it not collide with the first one but stay in contact. I have a manual algorithm that make tests on the different blocks of the two groups to push it up enough to make them not collide but it is a bit intensive. Do anybody know if unity physic engine can help here? The main problem is that after I receive the collision I can not move the moving sphere up and recheck manually first of all because there's no Check for rectangles and on the other hand if I want to be notified by the physical engine after I move the moving sphere up (to see if it still collides)I need to wait a new frame which is not feasible in my case. P.S. I'm using unity engine. |

0 | Best client server architecture for a mobile management game? For the past year I have worked on a small company that develops a traditional browser based strategy game, of the likes of Travian or Ogame, but using a more interactive approach like Tribal Wars 2. The game is made in a simple php server without frameworks and a simple mysql database, and all of the game happens in a single static page that is changed through ajax calls and has a map made in pixi.js. The automatic updates are delivered to the client side through polling the server which then queries some specific database tables made for the purpose for changes. While this approach is solid and works, it has 2 big problems Having a mobile app is increasingly more important and there are not enough resources for having two separate codebases. Having a app which is simply a wrapped webview is also not a solution because the performance of a really complex page with a giant webgl map is, while usable, really subpar Polling the server for changes creates a lot of programing challanges that make some simple tasks really complicated and creates a lot of convoluted code if we dont want to hurt the game performance, as we are not going make dozens of database queries every 5 seconds. I want to start developing a game idea that I have that is basically inserted in the same genre and which is going to be, at least initially, mobile only. The real problem here is that after reading a lot on the internet, I am confused on what should be a good client server architecture for me to start prototyping in a way that I do not run in the problems mentioned above. Basically, above all, I want the server to be able to know which page screen state is each client looking at, and be able to send them messages when another client changes something on that specific screen. It would also be nice if the solution is something lightweight on the server side to be able to scale a little. Client side I was thinking about Unity because of being cross platform, of all the environment around it (ads, analytics, a lot of support and answers on the internet), and because I have previous development experience with it. Server side is the real question. Simple http calls will not work and so PHP is out of the equation. I have though about using node.js with socket.io to use websockets solving the polling problem. Is this a good idea? Would it be better to store the game state in a relational or nosql database in this case? Would this work on unstable mobile conections? Lots of people seem to use a c and sockets for unity. Would this be overkill in this situation? Taking this approach how would the data be stored? would it be feasible with a linux server or would I need a windows server? Would this work on unstable mobile conections? Don't know, I'm open to suggestions. tl dr I want to make a mobile management game in unity but am confused what to choose for the server side architecture considering that I want the server to be ablose to send a message to the client without the client asking for it. Is there anything I should take in account? Sorry for the broad question and thanks for the help. |

0 | Game (Physics) work in Unity Editor Remote but won't on Android? I have a script attached to a car game object that allows the player to tap the screen and then accelerate, the game object has a RB2D and collider set to it , it works fine in Unity Remote , but when I download the APK , as soon as I tap the screen , collisions go completely bezerk and the car just starts ignoring collisions , what's going on? As I need this to work to complete my game , as the player can move side to side with the accelerometer but I also want them to move forward when they touch the screen. Also , my game is 2D. Plus , since then , when the car ( my object) collides with anything else in the scene , it ignores it ( the obstacles just have Box Colliders on them). I had to freeze rotation so it could stop spinning out when it hit soemthing , now it just won't recognize collision at all. What's going on? The code I think is causing the error starts at line 32. I have obstacles the player has to dodge and they all have box colliders and an appropiate script attached to them as well ( so when they collide with my player , it destroys it) I've figured it out , Collision works when I first start the game , but when the player dies and I press "Replay" , it goes crazy. Here's the script that controls the enemy cars spawning , what the hell do I do to fix this? Code (CSharp) using System.Collections using System.Collections.Generic using UnityEngine public class EnemyCar MonoBehaviour public float speed public float acceleration 0.5f Use this for initialization void Start () Update is called once per frame void Update () speed Time.deltaTime acceleration transform.Translate(new Vector3(0, 1, 0) speed Time.deltaTime) void OnCollisionEnter2D(Collision2D col) if (col.gameObject.tag "Coin") Destroy(col.gameObject) I've done everything in the book trying to solve this , re install unity , add different colliders etc. What's weirder is that it is FLAWLESS in Unity Remote and the Editor , these issues only arise when I test out the apk. Here's how my game usually looks when the collisions work. Now when it collides with a car ( on android) , it just ignores it and is slightly pushed back. Help me!

The CursorManager will then update the cursor's world position and then then prompt the GridManager to find what's in the hex in order to update the UI with terrain unit info. My new addition is thus having the GridManager change the cursor's state depending on what's in the tile. You pressed up? Let's let the cursor state dictate what happens to the grid. So naturally I created a cursor state object in the CursorManager, but suddenly realized each state needed decent amount of shared information across different the two controllers. For instance, public class FreeCursor CursorState public override void ActionPressed() currState gridManager.selectTile(cursor.position) So this means the FreeCursor state would need reference to the GridManager object, reference to the cursor GameObject, and also a reference to the current state itself. All 3 of those are already in the CursorManager, so it's no problem, just throw them all in a constructor FreeCursor(CursorState context, GridManager gridManager, GameObject goCursor) But d'oh, when gridManager.tileSelected() completes, it should return the new state. So the GridManager should be saying public CursorState selectTile(Vector3 position) ... return new FreeCursor(this) ...Except now we're missing the GameObject and the current cursor state, which aren't accessible in the GridManager. So I could go one or two ways make the GridManager also contain a reference to the context, so it becomes return new SelectedUnitState(this, CursorManager) and changes our flow to be InputManager gt CursorManager lt gt GridManager. Or I could say screw it, throw the cursor state and GameObject into the GridManager and call it day. ...But both feel just wrong? The latter through combining two somewhat distinct controllers the former by making the state be passed it's own containing object like a poor man's reflection or something. Because if I do that, I might as well just use Unity's GameObject.Find(Cursor). Am I wrong to think this? And if so, is the problem with my implementation of the state pattern or the way I've laid out my 'architecture'? tl dr How do you handle a state pattern with data from multiple controllers? Thanks! |

0 | How can I randomize my speeds just once, each time values are changed in the Inspector? private void SpeedUpdater() if (changeSpeedOnce false) foreach (WaypointsFollower follower in waypointsFollowers) if (randomSpeed) follower.speed Random.Range(minRandomSpeed, maxRandomSpeed) else follower.speed speed changeSpeedOnce true I'm calling SpeedUpdater from inside the Update. The problem is that if I'm not using the private flag bool changeSpeedOnce it will give each follower speed a random value every frame but I want that when it's random it will give each follower speed only one random speed value that is why I'm using the changeSpeedOnce flag. but then I can't change the speed in run time when the game is running because changeSpeedOnce is false now. I'm stuck here. From one side I want to give only one random speed value to each follower but I also want to do it any time in the run time when I'm changing the speed value in the Inspector. |
0 | Random Direction Vector Relative To Current Direction I have a 2D vector where the x and y values are randomly generated using a range between 1 and 1 respectively. I use this as the direction to move an object in which works great. var direction Vector2(Random.Range( 1f, 1f), Random.Range( 1f, 1f)) What I would like to do is after some period of time, randomly generate a new direction vector, but this time keep the same "relative" direction that it currently has. Probably within 45 degrees or so on either side of the current direction. So I'd like to randomly generate a new direction vector within a range of 45 degrees on either side of it's current direction vector, and start moving in that new direction. Does that make sense? I'm not quite sure how to go about this, but I'm sure this isn't too difficult if someone could help get me started. Thanks! |

0 | Unity Adjusting 2D physics for different mobile resolutions I created a test project to see how different mobile resolutions affects Unity's 2D Physics. They way I handled the resolutions was to contain all the objects (including non UI objects) in a Canvas and use a Canvas Scaler component to adjust for multiple resolutions. Although this approach is probably not one of the ways the Canvas was not meant to be used, it works well when working with a single orientation. Despite the quick solution to handle the multiple resolutions, there seems to be the issue of the physics acting differently depending on what aspect ratio is being used. Images can be viewed here http imgur.com a p5wmf The green and blue blocks both have the Rigidbody2D and Box Collider 2D components. The floor (big white block) only has a Box Collider 2D component. As you can see from the images above, the different aspect ratios cause the blocks to collide with the floor at different times. Also, when using rigidbody.addforce in the Y direction, the different aspect ratios cause the blocks to jump at different heights. Obviously these issues could cause an unfair advantage in a game with support for several resolutions. So how would I go about adjusting the physics so that the blocks fall and jump at the same rates relative to the different resolutions? Also if there is a more practical way to adjust for multiple resolutions that doesn't involve a plugin and doesn't break physics, let me know! |
0 | Overlap transparent particles without blending? (Unity) I'm trying to create a continuous output of light from an object (like the exhaust of a space ship), and I thought I'd use particles to achieve this. But I'm running into a problem with alpha blending. I'd like to decrease the particle system's alpha over time, but because there's such a high density of particles, they end up evaluating to a solid color for most of the system's duration. This blog post basically shows what I'm trying to achieve https mispy.me unity alpha blending overlap The idea is to use a stencil test to make sure pixels in a sprite particle aren't gone if they're overlapping another sprite particle. Pass Stencil Ref 2 Comp NotEqual Pass Replace Then the author adds an alpha cutoff to make sure transparent pixels on an underlying sprite don't prevent new pixels from being written. half4 frag (v2f i) COLOR half4 color tex2D( MainTex, i.uv) if (color.a lt 0.3) discard return color But this solution requires you to eliminate soft edges, so I'm thinking it wouldn't look good in a particle system. The author also hinted at an alternate solution involving ZTest, but I can't visualize what that would be. |

To try the transparecy first I imported a PNG image as a plane on Blender and adjusted the necessary things in order to make work the transparency. You can appreciate the settings I used in the following image Until there is all fine. The problem appears when I import the fbx in Unity. The material that I created with the png image is not well visualized. When I import the fbx object in Unity, this messages appears in the Materials tab What do I have to set here in order to visualize well the image with its alpha channel working? Furthermore, if I try to change the material settings it is impossible because I cannot click the different options as they are disabled Can anybody tell me what I'm doing wrong? I don't know if my error is when creating the material in Blender or when I import the fbx in Unity. |

0 | How to properly synchronize achievements on Google Play Services? I have a mobile game with achievements on android, so the achievements are using Google Play Services. For a couple of reasons, I must track the progress on the achievements locally (or so I think) because If the user is not connected to the internet Some achievements have complex "step" that the simple increment system provided by the Google Play Service (number of steps, current step) cannot track. When the game starts, the local copy data on the achievements is synced with what is on Google's server. Either both are the same, do nothing the local copy has more progress than what is shown on Google's so update Google data (that happens if you play offline) the copy on Google's server show more progress than locally so update the local data (that happens if you play on a different device) Clearly, there's a way to abuse the system here. Given two players with different achievement progress (Player A (lots of achievements), Player B (few achievements)) they can do the following Using Player B's device, Player B signs out of his account Player A signs in (the current active Google Account is now Player A) Start the game All of Player A's achievements are synced locally (they had more progress than the previous local version of Player B) Player A signs out and Player B signs in Re start the game the local copy will show as more advanced than Player B achievements, therefore they will get updated. How do people deal with this problem? Not care? Key the local achievement progress to the logged in player (which causes some problems)? Not to track anything related to the achievements locally (but how to deal detect being offline?) |

0 | Should I package and sell my game on the unity3d asset store? I'm trying to figure out if I should refurbish and refactor a game I and some friends have made. It's released on kongregate and wasn't a super hit but I feel there's a lot of interesting techniques and solutions going on that new or intermediate developers would like to see. The only thing that's holding me back is that I don't know if people are interested in it at all. Would you be interested in buying the source code and assets for this game? Check it out and you'll see that there's a lot of things happening in the game. If we packaged it and sold it, we would of course tidy it up a bit which would involve more work so I would really appreciate your honest opinion. We've looked around and haven't found actual released games in the unity3d asset store. Maybe we just didn't look enough though. We're thinking of setting a price tag of between 150 and 200 . What's your opinion on this price? And in general, what's your opinion on selling assets and source code? Should I be wary of any legal implications (like my customer licensing my stuff and then forbidding me from selling it)? I posted this over at UnityAnswers as well but I know I rather go here for gamedev questions so I'm hoping other unity devs will drop by here too. Edit Reconsidering after getting some great advice we'll probably rip out the assets only and market those as space stuff or something. We'll then market the assets with the help of some free classes of code showing off some of the examples that were hard for us to do when we were (more) beginners. The unify wiki might benefit from having some of the code that we've done and that isn't all that hard but a bit tedious. If we actually "finish" the game (it is indeed an asteroids spinoff and was never intended to be anything else, apart from some sandbox modes we've been experimenting with) we'll probably sell it with a decent price tag for an indie game like this. |

0 | What is a good way to code dialogue creation? I'm thinking of making a single method class something that will handle my dialogue in the game. AKA, something like Main text Choice 1 Choice 2 So I want a method that will able to put different strings into the main text section and also different strings into the Choice options. I've been thinking about solutions, and so far I've come up with just a simple method that accepts parameters for main text, choice1 and choice2 problem being that the strings called will be quite long and I think it looks a little clumsy? Also I won't want to have 2 choices every time, OR I want to have multiple "pages" of dialogue show up before you need to take an action. This would require me to overload methods which may turn out quite ugly? So yeah I don't have a lot of experience with this and method overloading is all I've thought about for now. I've given thought to interfaces abstract classes but I'm not entirely sure if they're even relevant for what I want to do. Any thoughts? |
