0 | Bounce with multiple collisions Here's the problem I'm writing an Arkanoid like game in Unity 5.3. I'm using 3D physics and simply ignoring z axis in computations. No gravity, 0 drag and velocity reset every bounce by script. My ball has sphere collider and rigidbody with continuous dynamic collision detection on it, and bricks have box colliders with continuous detection. They are set like tiles, one by one, without gaps. The problem occurs when a ball collides with two bricks at once, which causes a wrong bounce angle. Smaller sphere colliders makes this situation occur less often, but causes the ball to ignore collisions sometimes and phase through a single brick. I know the probable reason for this bug, I think a collision with two objects affects ball physics twice. The question is how to avoid it? |

I tried adding a prorperty above the if statement "GameObject build", I tried doing Farm build new Farm() above the if statement also but still get the initial error. I have a folder titled "Resources" and confirmed a prefab labelled "Farm" is there also. Could it have anything to do with the "static" prefix for the method? |

0 | Unity Procedural Build Exe Creation I want to export ingame items to seperate data files. Those files should also be "openable" to display information about the item. My idea is to create every item as an .exe that will open a small windowed unity app with and image and some texts tabs. How would I handle this "procedural building of .exes" from within another application? For exeample I have a game with an inventory. And when I press "export to file", the item is build to an "item data exe file", that is then portable and openable as a standalone "item previewer". Thank you for help. For the start a general assessment of this idea could also be helpful. |
0 | Math.Clamp won't limit my position until movement is ceased The program is in a top down view, with Y going up (or forward depending upon how you see it), and X going from left to right based on the camera view. I am attempting to set the minimum and maximum values of my main character's x y axis movement through the float "clamp", under the struct "Mathf". When my ship passes the minimum maximum value on either axis, it doesn't stop it. If you release the movement key after passing the point, the character will appear directly on the minimum maximum point that was passed. See the gif below. Gif here http gph.is 22fdHv4 Below is the current script running for both player movement and the boundary, attached to the main character. using UnityEngine using System.Collections public class ShipMovement MonoBehaviour public float xMin public float xMax public float yMin public float yMax public float speed 2f public float shotSpeed 4f public float nextFire1 public float nextFire2 Animator anim public GameObject shot public Transform shotSpawn public float fireRate 0.25f void Start () anim GetComponent lt Animator gt () void FixedUpdate () GetComponent lt Rigidbody gt ().position new Vector3 ( Mathf.Clamp (transform.position.x, xMin, xMax ), Mathf.Clamp (transform.position.y, yMin, yMax), 0.0f ) if (Input.GetKey (KeyCode.W)) transform.Translate (Vector2.up speed Time.deltaTime) anim.SetBool ("moving", true) if (Input.GetKey (KeyCode.S)) transform.Translate (Vector2.down speed Time.deltaTime) anim.SetBool ("moving", true) if (Input.GetKey (KeyCode.A)) transform.Translate (Vector2.left speed Time.deltaTime) anim.SetBool ("moving", true) if (Input.GetKey (KeyCode.D)) transform.Translate (Vector2.right speed Time.deltaTime) anim.SetBool ("moving", true) else anim.SetBool ("moving", false) if (Input.GetKey (KeyCode.Space) amp amp Time.time gt nextFire1) nextFire1 Time.time fireRate Instantiate(shot, shotSpawn.position, shotSpawn.rotation) if (Input.GetKey (KeyCode.X) amp amp Time.time gt nextFire2) nextFire2 Time.time fireRate Instantiate (shot, shotSpawn.position, shotSpawn.rotation) if (gameObject null) Application.Quit () Although I am not sure, I suspect it may have something to with the way I am controlling the movement. I have had issues with what I have written in the past, especially with animations and moving left right while also moving up down.

0 | Player motion and combo systems Where do you usually implement player motion when going through the state machine of a combo system? An example, when player presses X Y it must do an uppercut like movement (Like street fighter) where the player jumps and hits. Another example could be the Devil may cry series where you can press down sword button and the enemy is thrown up and the player authomatically jumps to let player hit target in the air. When creating a combo, you have 2 things to take care of. One is the media that will be played when the combo is done (sound, animation, etc...) and the other the movement of the player when doing this combo. How do you handle the movement of the player? I have 2 posible options 1) Include the player motion (translation, rotatio, etc...) in the animation 2) Delegate the player motion to the combo nodes while they are being linked. First option could be the easiest but seems a bit restrictive. For example if you want to let the player do some other action while the current combo node media is playing (ej. jumping) could be tricky (Jump hit). Second option would need to have some many diffeernt nodes (We could use some kind of delegates here to minimize the node count(IOC)) to cover all the motion needs of every part of the combo. What do you think. Am I thinking too much? Cheers. |

0 | How do I make my character attack on the side of the character that I click the LMB on (Unity)? This is a top down game, I guess I should also mention that the character is not centred on the screen and the attack should be in 4 different directions. The attack's direction should be based on which side of the character(up, down, left, right) that you click on(this should also be universal on the screen, the only deciding factor should be the character and the mouse). I really have no clue where to start on this problem. |
0 | Shooting projectiles towards mouse position in Unity 2D I'm currently creating a scrip that handles the projectile movement and it's almost where I want it to be. Currently the script correctly instantiates the projectiles, moves the projectiles towards the mouse and deletes them off screen, but the speed of the projectile is not constant (faster or slower depending on how close the mouse is to the player) and after the projectile is fired, it follows the position of the mouse until it flies off screen. public class LetterController MonoBehaviour private List lt GameObject gt letters new List lt GameObject gt () public GameObject letterPrefab public float letterVelocity Vector3 direction void Update() direction Input.mousePosition direction.z 0.0f direction Camera.main.ScreenToWorldPoint(direction) direction direction transform.position if (Input.GetMouseButtonDown(0)) GameObject letter (GameObject)Instantiate(letterPrefab, transform.position,Quaternion.identity) letters.Add(letter) for (int i 0 i lt letters.Count i ) GameObject goLetter letters i if (goLetter ! null) goLetter.transform.Translate(direction Time.deltaTime letterVelocity) Vector3 letterScreenPosition Camera.main.WorldToScreenPoint(goLetter.transform.position) if (letterScreenPosition.y gt Screen.height letterScreenPosition.y lt 0 letterScreenPosition.x gt Screen.width 20 letterScreenPosition.x lt 20) DestroyObject(goLetter) letters.Remove(goLetter) I tried moving everything from Update() into a separate function called Shoot() and called that from Update(). I tried putting Vector3 direction in its own Vector3 function and calling it in goLetter.transform.Translate. I also tried using LateUpdate(). Nothing I've tired has made any significant changes to how the projectile interacts in Unity. I'd like to have the projectiles move at a constant speed and not follow the cursor but rather travel in a straight line anyone got any clues? |
0 | Child GameObject doesn't follow parent's transform Look at this picture first I have model that has sword in his hand. I added a cube named "Attack Collision" and located to blade position. And then set the hand to parent. But when the game starts, sword moves but it's children "Attack Collision" doesn't move at all. The funny thing is in the scene, I tried to move the "sword", but only it's children "Attack Collision" was moved. Seems like the sword is somekind of locked, because it's transform can be change but not applied at all, it's just stand still there and only it's children that made from Unity was moved like this I made this model and animation by Blender and imported to Unity as .FBX file. What am I missing? |

0 | Switching between VR and Desktop (VR Controllers are not tracked in Unity Build) I am developing a VR App in Unity3D for HTC Vive Pro (Wireless) everything works well with VR in the usual way. (SteamVR Plugin 2.5.0 (SDK 1.8.19)) Except for some requirement reasons in the same Unity scene, I have to shutdown VR switch to Desktop mode and later at some point enable VR again. The moment, I enable it via script the VR display is ON, the HMD tracking works well but the Vive controllers are not tracked (position amp rotation), I can see the controller model rendered though in the last position when the VR was shut down but I can't get the updated tracking. The issue is only happening in the Unity Build. In the editor, it is working fine now after this change. To fix the issue in the Unity Editor I tried changing the SteamVR ActivateActionSetOnLoad method from Start() to OnEnable() as the error on re enabling was related to controller actions missing, that is now fixed cause of this change. e g private void OnEnable() if (actionSet ! null amp amp activateOnStart) Debug.Log(string.Format(" SteamVR Activating 0 action set.", actionSet.fullPath)) actionSet.Activate(forSources, 0, disableAllOtherActionSets) I am looking for a solution, to fix the issue in the Unity build?

0 | Creating Rope Physics for Unity I want to create a bungee jumping like game in Unity and therefore I need a rope physics.

0 | Creating a delay by using Invoke Is it possible to delay the effects of a script that is attached to a game object? I have 2 characters in a scene, both receiving live motion capture data, so they are both animated identically. I have rotated one by 180 degrees and placed it in front of the other one, to create the impression that they are copying mirroring each other. Each has several scripts attached to them, of course... Now, I would like to be able to delay one character a bit (e.g. 1 sec) to make it look more realistic, as if one character is observing the other character and then copying its exact movements. Is it possible to do this by somehow using the Invoke method on the other character's Update perhaps? Or any other possibilities to achieve what I described? EDIT I used a buffering mechanism, as suggested by all the helpful comments and answers, instead of delaying, because delaying would have resulted in the same network data being used, except after a delay, but I needed the same old data being used to animate a second character to create the impression of a delayed copying... private Queue lt Vector3 gt posQueue private Queue lt Quaternion gt rotQueue int delayedFrames 30 void Start() posQueue new Queue lt Vector3 gt () rotQueue new Queue lt Quaternion gt () void Update() Vector3 latestPositions Quaternion latestOrientations if (mvnActors.getLatestPose(actorID 1, out latestPositions, out latestOrientations)) posQueue.Enqueue(latestPositions) rotQueue.Enqueue(latestOrientations) if ((posQueue.Count gt delayedFrames) amp amp (rotQueue.Count gt delayedFrames)) Vector3 delayedPos posQueue.Dequeue() Quaternion delayedRot rotQueue.Dequeue() updateMvnActor(currentPose, delayedPos, delayedRot) updateModel(currentPose, targetModel) |

0 | Adding some new velocity to player in FixedUpdate. Should I use FixedDeltaTime or nothing? I am trying to learn how to move objects in Unity without using the built in features like AddForce etc. Some tutorials on Unity website (and other places) is where I have got most of my 'knowledge' so far from. This script for moving players (in topdown Space SHMUP) has been working fine for me and includes acceleration and artificial drag (basically 'smooth' movement, or like being on ice). I'm sure this code is overly long, bloated, inefficient and in most cases downright wrong, but it is written for me to understand it, rather than simply using Unity Prefabs and AssetPackages i download from Store.

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 | How to make player stay on a moving object I've made an obstacle course with various moving parts to test out movement of a player. In the obstacle course there is a section where there are multiple cubes moves from side to side, and you have to jump from one to the other. But regardless of their speed, I can't seem to get the player to stay on top of any of the moving cubes. I have no clue how to fix this my only guess would be to use materials, but I can't apply any to the character controller. I appreciate any suggestion that you can give. Also the movement is done as an animation that I created in unity in the animation window. Thanks, Nova |
0 | Issues with events changing game state I am currently experimenting with creating a turn based game using Unity and am trying to come up with a sensible architecture for structuring my game systems. So far I have decided to base everything around Game states. A game state represents a sort of "mode" of the gameplay, for instance "Select unit state" or "Game over state". A global game state manager holds a stack of these game states and can be called with pop (remove top game state), push (push the provided game state onto the stack) and replace all (pop all existing game states and push provided game state). Update is called on the top most element of the stack every logic frame. I also have Entities which exist on the scene and represent stuff like as game units, terrain, projectiles etc. These are standard gameObjects with behaviors, unity lifecycle etc. Finally there are a bunch of services which provide methods to handle stuff like menus and camera. The idea is that the game states handle the "logic" of the game such as player input, transitions between game states, calling the services and controlling modifying entities. I also use events to facilitate the communication between state, entities and systems to avoid coupling too much. These events are stuff like "Unit destroyed" and "Objective complete" which are listened to usually by entities, calls to move the camera, create entities and such are still called normally using the relevant service methods. Whilst this system works in theory I am having some issues with the interactions between events and game state logic. Consider the following Update of performActionState void update() Do something. Messanger.fireEvent(EventType.ACTION COMPLETE) GameSystemManager.pushState(new NewTurnState()) Objectives system listening for action complete void handleActionComplete() if (checkObjectivesAllComplete()) GameSystemManager.pushState(new GameCompleteState()) What I want to happen is for the objectives system to push a game complete state and finish the game. What actually happens is that the handle action complete pushes the game complete state, the rest of the perform action state update runs and a new turn state is pushed. The above example might be a bit simplistic but I see this as an underlying issue with my architecture. Most events would be fired due to a change in the state of the scene or completion of something, for instance a unit being destroyed or a unit entering a trigger area. The probability of the game logic needing to change state from the game states is quite high in these cases usually. I could easily fix the above sample in a number of ways, for instance I could move the checking of objectives into the start of NewGameState and invoke a pushGameState there instead to end the game but all the ways I can think of at the moment seem like hacks which will greatly increase coupling (New game state doesn't need to care about objectives) and code spaghetti. Any advice for ways I could potentially architecture around issues like this? |
0 | Why the main menu is not working on the second time when pressing on escape key to back to the main menu? I have two scenes. Main Menu and the main scene.

0 | Optimizing data structure for my text adventure? In my text adventure I'm making, I store the story data in a hashtable (I'm using unity's javascript unity script since I'm more comfortable with the syntax than C ). The problem is, the way I structure the hashtable means that it gets incredibly bloated very quickly (I've used the same structure in all of my text adventures across multiple languages. It quickly grows to nearly 1k lines long) which makes it hard to edit in the future (especially if I need to go back to edit certain parts later on) Here's the hashtable as it's currently structured public static var story "0" "text" "", "choices" "response1" "text" "", "nextPart" "1" , "response2" "text" "", "nextPart" "2" , "response3" "text" "", "nextPart" "3" , "1" "text" "", "lastPart" "0" , "2" "text" "", "lastPart" "0" If anyone could help me optimize the structure of the hashtable that'll make it so it's more easier for me to edit it in the future, that would be great Quick information for parts that may not be self explanatory "lastPart" indicates to the hashtable parser that the player has died and the number refers to the part where they chose the response choice. "nextPart" refers to the part of the story the response leads to. |
0 | How can I draw an outline in Unity3d? I am trying to highlight a rectangle of arbitrary height. I thought the easiest way to do this would be to create a separate "box" gameobject that outlines the rectangle.

(Line renderer on in the middle, scaled cube on the right) What's the right way to go about this?

0 | Unity assets file structure I'm writing a map editor for a game built with Unity (5). I want to reuse as much of the resources from the game as possible. That means textures and meshes. I know they are somewhere in the assets files, but I need to be able to extract that data during runtime since I cannot (and do not want to) redistribute those files. Additionally, given that the game receives frequent updates, I need to be able to calculate the offsets each time the editor is started. I also need to know how the textures connect to the objects in the game. In order to do that, I need to know what the structure of assets file is, or at least find a way to extract them all and then use hex editor to figure out how they're put together. I know there is a devxdevelopment tool that can do the latter, but I don't really have any money to spend on this. Can you give me any info or pointers that would enable me to figure this out? |

0 | Make the texture array node work with cubemaps? I am working on a procedural interior mapping shader in Unity's Shader Graph. Ideally, I'd like to feed it a set of cubemaps it can pick from semi randomly. However, it seems that by default the texture array asset one can provide to a graph does not support reading cubemaps. Does anyone have a way to use this, or perhaps a clever custom node or alternate texture mapping, so that I can read a number of cubemaps into the shader semi randomly? Preferably an arbitrary number, but even a fixed number would be somewhat of an improvement. |

0 | Procedural Islands Voronoi Pattern I'm trying to keep this as simple as possible, as I've found out the last few days this is a very difficult topic. I'd like to generate multiple flat islands, formed by a voronoi diagram. I've followed a long and (for me) difficult tutorial of building a procedural hexagonal grid just to find out it looks to artificial. I'd like to create a plane with faces divided in a voronoi diagram, and extrude multiple groups upwards to create islands. With that I'd like to achieve something similar as this http applemagazine.com wp content uploads 2015 10 image2.jpg Please help to get me started in the right direction, since my approach might be wrong in itself. EDIT I've found this https github.com jceipek Unity delaunay. Which draws lines in a voronoi diagram. Now I'm guessing the next step is to convert this to a mesh. Then I'd have to highlight random faces to be extruded to create the islands. Maybe this could be done with perlin noise, which I've just learned about. Extruding might not be the best way. Maybe deleting the faces that won't be land, and creating fall of edges (Like Wardy said). I'm doing my best to figure this out on my own, but any help is greatly appreciated. |

0 | Set box collider size in meters instead of percents TL DR Can I set the size of a collider in meters instead of fractions of the size of the object it's in? I'm implementing a classic NES game, and my scale is 1 meter 16 pixels. I have an 8x1x1m prism with a rigidbody, and I need its box collider to be smaller than it by one pixel on every side to have the dimensions (8 1 16 1 16) x (1 1 16 1 16) x (1 1 16 1 16). (I'm subtracting the width of two pixels from each dimension because each dimension corresponds to two sides.) When I set the size of the collider to (0.5, 1, 1), though, it interprets those numbers as fractions of the size of the prism instead of as meters. This results in a 4x1x1m collider instead of a 0.5x1x1m collider. Is there a way I can set the size in meters instead of percents? I'll save me a little bit of math, and, more importantly, it could prevent some floating point errors, especially if I switch to a scale with more pixels per meter. |
0 | Changes to one Unity trail renderer causes all of them to flicker I'm using Unity. So I have a prefab, and this prefab has a trail renderer component attached to it. However, for some of the game objects I want to stop the trailer renderer at certain points in time. But doing so seems to make all of the trail renderers blink flash off and on. I've tried changing time, disabling the component, and using Clear() while hiding the trail renderer behind the background before needing to be used. All of these makes all trail renderers flicker on the frame the change happens. I believe providing the code won't be helpful, it's just if(x) disable action, if(y) enable action. What can I do? |

0 | Unity application freezes on ios at pause When I play my game made with Unity on iOS device, and press the home button or let the screen close by time or by pressing the power button and then try to come back to the game, the game freezes immediately.

0 | How do you reference one game object from another? I am trying to reference a game object that was created in the editor and added to the scene (not created dynamically). How can I reference this object in a script added to another gameobject? For example I have a Mesh called QuantumCold B (in the editor), and I try to get its position in a script to be added to First Person Player, but instead I get Unknown identifier ('QuantumCold B'). Here is my script function Update () transform.RotateAround(QuantumCold B.position, Vector2,20 Time.deltaTime) Also is position the right way to get the Vector position on QuantumCold B? |

0 | What's the proper way to set up a texture atlas in Unity 3D? I am using Unity3d (free) to make a game with user defined content (i.e., load in a map, it'll build the level for you). Everything is working as expected, except for the rendering. Note the artifact seam along the edge of the two cubes. I am not entirely sure what is causing this, other than, perhaps a rounding error? At any rate, every mesh in my scene shares the same texture, with specific UV offsets generated at 1 8 intervals for each corresponding texture Playing around with the assigned UVs moves the artifacts around. For instance, the red brick texture has the issue between the top faces So clearly, I'm doing this in a suboptimal way. Is there something specific I'm doing wrong? Or is there a better way to build meshes with texture atlases? |

0 | What is an acceptable receive rate for a client? I've noticed that syncing a transform( in Unity, so a Vector3, and a Quaternion ) ends up being close to 1000 byes per second received on a client( send rate of 20hz ). Multiply this by a generous 20 entities a single match might have and that's about 15k 20k bytes per second. Is this too much? What should I be aiming for? What data rates do games typically have? |
0 | get position of GameObject on rendertexture from camera I'm rendering the camera output to an rendertexture on a plane. This works fine. But I want to put GameObjects on the rendertexture on positions of world objects that are visible on the camera. camera.WorldToViewportPoint(obj.transform.position) shows the correct positions, but is not mapped to the rendertexture. How can I do this? So it's GameObject in world camera input plane with RenderTexture world or local position of gameobject on top of rendertexture plane. |

0 | Usage of math.Atan2 in a 3D coordinate system with Unity I have a simple question on usage of math.Atan2 function with Unity in a 3D environment. I found this code on Unity's documentation for Math.Atan2. I changed it a bit to fit my needs. Vector3 waypoint Random.insideUnitSphere new Vector3(Random.Range(minX 1.5f, maxX 1.5f),prevPosY,Random.Range(minZ 1.5f,maxZ 1.5f)) waypoints are generated based on random unit sphere ( bounds of the plane they are on ) Vector3 relative transform.InverseTransformPoint (waypoint) float angle Mathf.Atan2 (relative.x, relative.z) Mathf.Rad2Deg I know how it works in a normal 2D coordinate system, however when switching to a 3D coordinate system, if I would want to move my character on the x z plane, then how does this actually work mathematically? I am assuming that it would be the angle between z and x axis? so in a mathematical equation would it be, angle Atan2(z x) or Atan2(x z)? Would both of them work? |
0 | PBR Graph option not showing up in Unity I downloaded the URP render pipeline into an existing project of mine (created using the 3D template) to try out shader graphs. All of the guides and tutorials I'm following use an option called the quot PBR Graph quot . However, I can not find that option in Unity. Did they change the name of the graph? How can I get access to it? When I open up a new project using the URP template, I have the option to choose the PBR graph, but not in my original project, so do I have to create the project with the URP template to begin with? The version I am using is 2020.2.3. |

0 | Not sure how to deal with overlapping UI As shown above, that is the issue I am faced with, tbh I am unsure how to fix it, I have tried and its coming to a point where I am drawing blank. I am quite newbie when it comes to this. So what I have now is multiple canvas each one displaying the name of the part that it is linked to and when the part moves so does the UI with it, the problem I have is that some parts dont move and therefore creating the issue of UI clustering together, so I need to move the UI rather than the parts. What I have tried is OnTriggerEnter and adding a box collider rigidbody to the canvas and tried to move the UI when they collided but I couldnt get that to work, probably down to me. if (gameObject.tag "car") get the gameObjects name that canvas is attached to canvasName.text gameObject.name newPos mainCam.ScreenToWorldPoint(this.transform.position) set the position of the UI newPos.x transform.position.x newPos.y transform.position.y 7f newPos.z transform.position.z canvas position if ( canvas ! null) canvas.transform.position newPos That is the code that I am using to attach the UI to the part. I was hoping to try something along the lines, but then again I am clueless. if collision is detected, newPos.y newPos 2f etc... So any help would be appreciated. Apologies if that was explained bad. |

0 | C (Unity) Use a method common to multiple classes with the same base class The Problem I'm building one of those empire kingdom building games and so I am trying to create an efficient way of making a "ResourceManager" class handle the games resources (wood, food, iron, stone). I currently repeat a function 4 times to do the same thing. Attempt 1 I created a "Resource" class (abstract) and derived the four resources from it. In each resource there are multiple methods which are similar Example Food.CS new public static void AddResources(int amount) Player.currentFoodSupply amount foodText.text Player.currentFoodSupply.ToString() Compare to Iron.CS new public static void AddResources(int amount) Player.currentIronSupply amount ironText.text Player.currentIronSupply.ToString() The AddResource() function is static because I have other scripts (like buildings, when they get upgraded) needing to communicate with each resource. The base building class currently has a method like this public void DeductResources() Food.DeductResources(FoodCost) Wood.DeductResources(WoodCost) Iron.DeductResources(IronCost) Stone.DeductResources(StoneCost) This seems like it's so repetitive that there needs to be a more efficient way to do this. Attempt 2 A "ResourceManager" class that anything to do with the 4 resources can go through this one script. I can update that one script instead of numerous scripts that does something with the resources. Where I am undecided is this one public static void DeductResources(Resource resource, int amount) if(resource.GetType() typeof(Food)) Player.currentFoodSupply amount resource.resourceText.text Player.currentFoodSupply.ToString() else if (resource.GetType() typeof(Wood)) Player.currentWoodSupply amount resource.resourceText.text Player.currentWoodSupply.ToString() else if (resource.GetType() typeof(Iron)) Player.currentIronSupply amount resource.resourceText.text Player.currentIronSupply.ToString() else if (resource.GetType() typeof(Stone)) Player.currentStoneSupply amount resource.resourceText.text Player.currentStoneSupply.ToString() It looks like it works and I can't see a way around calling the above method 4 times as I need to know how much food or wood to add or deduct. Does anyone have any suggestions please on how to improve this code call the method once? I'm always willing to learn! Thank you |
0 | Use both AddForceAtPoint and change velocity property? I'm using Rigidbody2D for some game objects. It seems that when I AddForce() or AddForceAtPoint(), the game objects are mostly affected on the Y axis and hardly at all on the x axis. I don't understand why. To really get any effect on the x axis, I need to have a very strong force like 10 000. But the effect on the y axis is then extremely strong and shoots the object out of screen, yet only nudges the game object on the x scale. I believe that the problem with the y axis is because I use .velocity to move the character. But I don't know how to change the velocity directly without doing that. What should I do to use both forces and set velocity on the same object? |
0 | Avoiding audio transcoding in Unity? I'm working on a project where I only have access to MP3s versions of audio tracks I'd like to use. Unity is trying to be helpful and recompressing everything as Vorbis, which is not ideal due to quality loss. Even if I override the audio clip settings and set it to use MP3, Unity still transcodes the file for me, resulting in quality loss. I can set the clip to PCM, which would avoid re encoding the file into another lossy format, but the resulting file size is too large to be practical. In a perfect world I would have WAV versions of all the tracks I want to use, but that is not the case. Is there anyway to tell Unity to use the file the way it is and to leave it alone and not recompress it? For the record I am using Unity 5.3.1 and my project target is iOS. |

0 | why is my (from example) shader appearing as black? I have the following (very simple) shader pragma kernel CSMain RWTexture2D lt float4 gt Result numthreads(8,8,1) void CSMain (uint3 id SV DispatchThreadID) Result id.xy float4(1,0,0,1) Here is the dispatcher code using UnityEngine using System.Collections public class SkyShaderDispatcher MonoBehaviour public ComputeShader shader public RenderTexture output void Start() RenderTexture output new RenderTexture(256,256,24) output.enableRandomWrite true output.Create() void Update() RunShader() void RunShader() int kernelHandle shader.FindKernel("CSMain") shader.SetTexture(kernelHandle, "Result", output) shader.Dispatch(kernelHandle, 256 8, 256 8, 1) which is the default red shader (it makes the texture red). However, when I put the texture in a material and give that to an object, then that results in the object being black. Anyone seeing what I'm doing wrong? As the shader is the default example right now it should work suggesting that maybe something is wrong with the texture? Edit Trying to fit the same code on a skybox also fails. I have changed the dispatcher code into using UnityEngine using System.Collections public class launchClouds MonoBehaviour public ComputeShader shader private RenderTexture output void Start() void Update() RunShader() void RunShader() int kernelHandle shader.FindKernel("CSMain") RenderTexture output new RenderTexture(256,256,24) output.enableRandomWrite true output.Create() Material mat gameObject.GetComponent lt Skybox gt ().material mat.SetTexture(" FrontTex",output) mat.SetTexture(" BackTex",output) mat.SetTexture(" LeftTex",output) mat.SetTexture(" RightTex",output) mat.SetTexture(" UpTex",output) mat.SetTexture(" DownTex",output) shader.SetTexture(kernelHandle, "Result", output) shader.Dispatch(kernelHandle, 256 8, 256 8, 1) but that turns the sky black rather then making the sky red. This is using unity 5 32 bits with DirectX11. |

0 | Checkerboard using Shadergraph In Unity Shadergraph, how can I create a checkerboard pattern that works independently of the size of the quad that it is applied to? Here's what I got so far. Since I have set the Frequency to 10x6, this will work for a quad that has a scale of 20x12. However, if I increase the scale of the quad, the checkerboard will get stretched to fit. But instead, I would like it to quot add more squares quot to fit the new size. Is there a way to get it to somehow use the size of the quad instead of manually specifying the frequency? |
0 | Reloading scene in Unity gives weird result I am making an infinite racing game where you fly an airplane while trying to avoid obstacles. I recently finished my menu that comes up when you die. When I press the restart button that simply reloads the current scene like this SceneManager.LoadScene(1) it gives me a weird result. The obstacles starts generating at about the same position as you died previously. I never get this problem when I start the game with the Unity play button. The only thing I could think off was player prefs. It should not affect the generation of obstacles but tried anyway to use PlayerPrefs.DeleteAll() before reloading the scene, but that did not work. What could be causing this strange problem? |
0 | Examples about how to tie AI actions to animations? I wrote a simple test AI for a character and all that it should do is to be idle while a parameter is below threshold otherwise it should perform actions based on other parameters. So for example if X lt 0.5 gt Idle state else if A gt 0.3 gt go to point A and perform action A else if 0 lt A lt 0.3 gt go to point B and perform action B I do have the code for the AI state machine in place but now I am stuck about how to build the animator that goes with this AI. I did use the standard AI 3rd person prefab in Unity and it moves correctly, since the controller script has the logic for moving already integrated but how do I make the entry for action A and B? Do I add the animations in the blend tree of the animator, and then from the AI script I call the animator play function for a specific animation? Do I set parameters for such animations so when the variable X and A change the blend tree read them directly and transition automagically? All that I can find around is just the usual AI examples for FPS which use the same patrol chase investigate sequence but they are mostly moving or chasing not necessarily executing different animations. Any suggestion would be more than welcome |
