0 | Building a game project in C for Unity in VS? Say that a project needs to be created from scratch for later use in Unity, for scripts. What is the ideal way to setup this without using a template in Visual Studio? Can this be created in C with some simple classes and one or two game loops? |
0 | Saving settings when exiting the application I created a static class CustomPlayerPrefs, it has a WriteToDisk() method that writes the saves to disk. For saving I am using Application.quiting event RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen) static void Init() Application.quitting WriteToDisk But on android it never works. I know that applications are not closed but paused, but it doesn't even work when I restart the device or force the application to stop. How to fix this or how to make it better? Need IOS and Android support. |
0 | How do I correctly set up a Unity animation to move? I downloaded a custom .fbx model from the asset store, imported it to my project and placed it in my scene. I then created an animator controller and added it to the object. To get the animations (that came with the model) into the animator tab, I dragged them onto the model in the hierarchy. I then set the one animation to default and pressed play, but in the game window, the model didn't move. What might be going on? The only time it did something was when I set it to "play from start" but that made it go through all the animations. I'm quite new to Unity 4. If you need any extra information, please ask. |
0 | Jerky Character movement after adding mouse orbit script I added a custom mouse orbit script to my project. When the right mouse button is clicked, the camera can be rotated around the player.

0 | C in Unity with dependencies I am currently creating a c program to eventually use in Unity. This c program contains references to libraries like OpenCV and dlib, referenced with a include statement which calls in other files, which are installed on my machine. My question is How do you compile your c project so that it runs in Unity completely self contained? i.e no reference to external files are needed, and all that are references are included within the program. Is there a specific tool to use, or a useful tutorial on the net? Thanks for the help. |
0 | Nested Coroutine Movement is slugish So I have a few AIs walking between waypoints. What I want to accomplish here is to have my AI move to the waypoint, when he reaches it, he must stop, wait for a few seconds (Not walk just stand still), then move to the new waypoint. Lets pretend he was observing while at this point. Issue right now He moves to the waypoint with a twitchy behavior where he would usually avoid objects, sometimes gets stuck while moving to objects or its like the AI cant decide what to do, move or stand still. Without the Waitforseconds method the AI avoids objects perfectly. Please note I want to use Coroutines for this even if you wouldn't use recommend it for this. If you have a suggestion for using Unity's Random to decide when he stands still after reaching a point or not, that would be a bonus for me. We define all fields and call the FSM() Coroutine with a default patrol state in the Start Method, from Here, This is my Code Update Implemented A Boolean IsMoving variable This works to some extent. The AI now moves perfectly to the waypoint. The Twitching however continues once the AI reaches the waypoint vicinity until he leaves the waypoint radius The movement then continues to a normal state. IEnumerator FSM() while (alive) switch (state) case State.PATROL StartCoroutine(Patrol()) break case State.CHASE Chase () break default break yield return null lt summary gt Patrol will move to a waypoint if too far, otherwise move to a next waypoint if one is reached. lt summary gt IEnumerator Patrol() Sets a common speed for the agent to move in. agent.speed patrolSpeed Now we want to check the position the character is at vs the waypoint location If i am too far, move closer My Position Waypoint Indexes We Set Multiple if (Vector3.Distance (this.transform.position, waypoints wayPointIndex .transform.position) gt 2) Telling the navmesh agent where to go. agent.SetDestination (waypoints wayPointIndex .transform.position) false, false Specifies if we are jumping or crouching character.Move (agent.desiredVelocity, false, false) Now we want to check the position the character is at vs the waypoint location If i am at a waypoint, move to a new index else if (Vector3.Distance (this.transform.position, waypoints wayPointIndex .transform.position) lt 2) character.Move (Vector3.zero, false, false) yield return new WaitForSecondsRealtime (6.0f) wayPointIndex 1 Move towards a new waypoint in the waypoint indexes flags Move to a random waypoint wayPointIndex UnityEngine.Random.Range (0, waypoints.Length) else Doesn't move, plays the idle movement We know this point wont be reached but if so... character.Move (Vector3.zero, false, false) yield return null |
0 | Unity HDRP draw order doesn't change when asset is set to higher priority? I don't like the way that light got baked into part of my mesh. It might make sense for me to try to blacken that area of the lightmap in Photoshop, but first I tried to just hide it with a probuilder object that uses an unlit black material I changed the priority of this object from 0 to 1, higher than any object in this scene, or at least the floor object, but it does not draw over the floor in Game View. I tried using a higher number and setting it beneath the floor instead of intersecting it, but it is just being rendered the usual way. Also note that I have a UI Canvas component being drawn in ScreenSpace, in case that has anything to do with it. How can I get this object to render in front of the floor while it is intersecting the two front faces, like in the picture? |
0 | Gravity well shader for Unity2D I'm trying to find or create a gravity well distortion shader for Unity. I've been looking around and all I can find are "lenses" which bend space around a black hole. I'd rather have a distortion that "pulls" or "bends" the image behind into a small hole. Essentially, what this would look like if viewed from above (ignoring the sphere) I can't seem to find any examples or a common terminology for it. |
0 | Unity 5 Virtual Reality Supported Text shimmering aliasing in GearVR I've spent the last 2 days trying to figure this out but have not come up with a conclusion. I'd appreciate if anyone has experienced the same and any thoughts. Basically, I'm noticing that if I have a scene with text in it (world canvas and UI text component), when I build for GearVR with Unity's VR support, the text aliases like crazy. To be honest I'm not even sure 100 if it is plain old aliasing. The text just constantly shimmers. I tried moving things around in case it was z fighting but it seems it is not. I tried enabling anti aliasing from the quality settings and neither does it seem to make a difference. I tried tweaking the Canvas Scaler Dynamic and Reference pixels unit settings (which are not entirely clear to me from the docs btw). But at most, I was able to make the text slightly blurry as mentioned in the Unity VR guide and it barely helps. I tried making the canvas and text huge and then scaling the canvas down to 0.05. finally I tried making my text bold and bigger. And that seemed to mitigate the shimmering to a certain extent but not 100 . But I've seen Unity apps for GearVR that don't exhibit this shimmering issue. So I am wondering what else might I be missing. I'm on 5.3.3.p3 if it makes any difference. |
0 | How do you actually build once you encounter the 'Too many method references' error? I'm making a very simple mobile F2P arcade game in Unity After adding SDKs for facebook, gamesparks, firebase, and appodeal I coud not build, getting the "Too many method references 76221 max is 65536" error. The solution from Too many field references 70613 max is 65536 is apparently to export an ADT project, import it into Android studio and go from there. I built following these instructions, and after building my Android studio project had errors relating to the facebook SDK similar to here Unity exporting android project with Facebook SDK issue The solution proposed there is to copy all the .aar from your Unity project to files to the Android studio project and add lines to the build.gradle file referencing them, which I did. After doing all that the 4 facebook related errors are gone but one new one appears Error more than one library with package name 'android.support.v7.appcompat A proposed solution for that is to search for the offending file and delete it in windows explorer but there is nothing with that name in my Android studio project folder. I tried removing some .aar files with appcompat in the name but I ended up reverting to the previous 5 facebook errors This whole thing has been a bit of a nightmare and I have no idea what I am doing. I would love to hear from someone who encountered this error and got past it and was able to build their game again. Surely this must be a common issue for anyone making a commercial mobile game in Unity? |

0 | Player going out of boundaries So, I been following up the Space shooter tutorial on Unity, I had an issue where the project was acting up with an alpha version, so I was able to get a version that worked on a old release and applied all the new things I developed But suddenly, my ship is acting up when getting closer to the boundary of its movement This is the player movement code public class playerMovement MonoBehaviour public float speed 0.0f public float tilt public Boundary boundary void FixedUpdate () float moveHorizontal Input.GetAxis("Horizontal") float moveVertical Input.GetAxis("Vertical") var movement new Vector3(moveHorizontal, 0.0f, moveVertical) var rigidBody GetComponent lt Rigidbody gt () rigidBody.velocity movement speed rigidBody.position new Vector3 ( Mathf.Clamp(rigidBody.position.x, boundary.xMin, boundary.xMax), 0.0f, Mathf.Clamp(rigidBody.position.z, boundary.zMin, boundary.zMax) ) rigidBody.rotation Quaternion.Euler(0.0f, 0.0f, rigidBody.velocity.x tilt) System.Serializable public class Boundary public float xMin, xMax, zMin, zMax And this is the player boundary properties It used to work previously moving forward to the alpha, now I'm working on 2019.2.0f1, but since working on the alpha this is the behaviour I'm having As you can see, getting closer to the player boundary, takes the player out of the play area, and I can't determine why this might be happening. I already tried removing the Math.Clamp, as I though there migth be bug with the function in this version, but even without it, the problem is present. |
0 | Unity directional light for a day night cycle on a hex sphere So I am trying to create a Day Night cycle on a sphere but it doesn't work the way I want it to. As the model is hex tiled, you see the edges of the hex tiles also lit up like below. I am using a directional light source for the same. I don't want the above effect. I want it to ignore the edges and just be a straight line instead. Something like below Is there a way inside Unity that I could achieve this effect just using the lights? |
0 | Making plane with quad I'm a beginner Unity 3d developer. I want to keep quads one aside another touching each other and use that as a road for making an endless runner game. The problem is each of the quads have their own box collider thus the car bounces a little bit sometimes. Is there any way to get those stuff connected with each other and make the whole thing behave like a single plane? I know using a big box collider covering all the quads in the repeating unit is gonna work but I don't want to use that. |

0 | How to offset a 2D GameObject by a pixel amount? I'm extremely new to game creation. I'm playing around with creating a 2D Unity game. The scene is setup from the default Unity 5 2D template. Following a tutorial, I've created a TerrainManager GameObject and Script. The script instantiates tiles and sets their position using a standard double loop. I've found a 2D isometric tile set. Each tile is visually rendered as rotated around the vertical axis by 45 degrees, creating more of a diamond shape rather than a square. This requires that every second tile be offset by half the tile width on the x axis, and half the tile height on the y axis. As each tile is of a different height, one can not simply offset the tile on the Y axis by half its height. Each terrain "layer" is 16px tall in the PNG. Some PNGs have a single "layer", some have multiple "layers". (For instance, a single layer water tile is 83px in height, while a dual layer "grass on top of dirt" layer is 99px in height. As the game object expects the transform.position as a Vector3 in (I assume) game units, I do not know how to compose this using pixel values. So the question I have is, how do I achieve the 16px y axis offset of the game object? I'm more than happy to provide additional details if needed. |

0 | How to split 2 teams for a FPS death match game in Unity? I'm making a playable one level only FPS death match game in Unity. I'm in the part where the AIs now can find and shoot their own target and keep looping to find targets until nothing left. Every AIs and including player were tagged with tag "Target" for the AIs to randomly find their target. (I already excluded self finding). Now I want to split them in 2 teams. And here is the thing that I keep wondering. Should I use 2 tags for 2 teams (like team red, team blue for ex) then make and attach 2 scripts separately for each AI in the team (the logic in the script will be like "team red" will find game object with tag "team blue" and vice versa). Is that how it works? Is there more efficient way or should I say, "smarter" way to work around this problem?

0 | Unity objects behaving different when NetworkTransform is used to sync movement I am experimenting with some simple multiplayer networking in unity. Currently I have a plane object as the ground, and a cube prefab as the player object. I have a network manager with round robin spawn and the built in HUD. The cube has simple movement control (up down is forward backward, left right turns the cube). I can successfully start a game, build it, and add a client from the built app. However, when movement gets sent over the wire, the non local player cubes in the game appear to "tilt forward," seemingly from the drag that the cube creates against the plane while moving. Strangely, when moving the local cube, no such tilt is experienced. Here is a gif which illustrates In the above gif, the cube being moved is in the foreground window. Notice how the cube is only tilting in the other window. Here is Update function of the Cube controller script Update is called once per frame void Update () Change translation float moveAmount CrossPlatformInputManager.GetAxis("Vertical") Vector3 deltaTranslation transform.position transform.forward movementSpeed moveAmount Time.deltaTime localRigidBody.MovePosition (deltaTranslation) Change rotation float turnAmount CrossPlatformInputManager.GetAxis("Horizontal") Quaternion deltaRotation Quaternion.Euler (turnSpeed new Vector3 (0, turnAmount, 0) Time.deltaTime) localRigidBody.MoveRotation (deltaRotation localRigidBody.rotation) MoveCamera() The ground is a plane with a rigid body and doesn't have a network identity or transform.

0 | Problem when trying to use rb.MoveRotation in Unity OK so I learned that rb.MoveRotation is different from rb.transform.Rotate(). But I am having trouble using it and hoping you can help me. I usually use transform.translate(Vector3.forward) (after using transform.Rotate(x,y,z)) , so that I know that will always make object move in the direction its facing. But this isnt working when I use rb.MovePosition. The object rotates when i remove the MovePosition line, but then for some reason doesn't when its there. I've tried multiple things as you'll see in the code. I cant understand also why, if I use the bottom commented attempt in my code, and then press D in game, it will go in the direction its facing and then get stuck. I've commented in my code to try to explain whats happening. What is the correct way to move the position of the player now I am using MoveRotation? I want to base my movement of the direction that the object is facing and not in world coordinates. Thanks void HandleKeys() if (Input.GetKey(KeyCode.A)) if (!facingLeft) rb.MoveRotation(Quaternion.Euler(0, 90,0)) facingLeft true rb.transform.Translate(Vector3.forward speed Time.deltaTime) if I remove this line, the character does turn and face left . But when its in he doesn't and both keys make him move right (and face right) also tried rb.MovePosition(transform.position Vector3.forward speed Time.deltaTime) this results in it going Vector3.forward in world coords rb.MovePosition(transform.position rb.transform.forward speed Time.deltaTime) this makes him go RIGHT gt ?? and the objects facing RIGHT why???? if (Input.GetKey(KeyCode.D)) if (facingLeft) rb.MoveRotation(Quaternion.Euler(0f, 90f, 0f)) facingLeft false rb.transform.Translate(Vector3.forward speed Time.deltaTime) if i leave this in, and the one marked above, then it works but only once, so if I press A then, D he heads right but wont turn round, if I press D first he just goes right if (Input.GetKeyDown(KeyCode.Space) amp amp IsGrounded()) rb.AddForce(Vector3.up jumpForce, ForceMode.Impulse) |
0 | How to adapt my mobile game for different aspect ratios? Before I start, I'd like to note that I work in the Unity Engine, but the basic theoretical stuff should be similar just about anywhere. It's not really hard to get the game's camera World view or UI to scale to many types of devices with different pixel counts as long as they have the same aspect ratio. But devices in general, and especially mobile phones, have all sorts of variables, aspect ratios can be anywhere from 16 9 to 20 9, and there are all sorts of different types of notches too. For this question I'm primarily going to ask about the aspect ratio and not touch on notches for now to stay on topic, but if you could explain how I can handle notches, that would be a good bonus. So, how do I make a game for a mobile device, that can be played in portrait and horizontal mode, on anything from small 16 9 screens like the Samsung Galaxy S5, to larger 19 9 aspect ratio (A notch) in the Google Pixel 4? Unfortunately due to IP restrictions, I can't show art, and I can't reveal the core mechanic of the game. but I have created a general mock up of what the ideal world UI scaling would look like The UI needs to be able to scale to the edges of the display like any other game. But the edges of the world need to be the edges of the screen (There needs to be walls that appear at on all 4 edges of the screen), however because the game is physics based, the walls can't actually move else it would cause inconsistencies between in the game from device to device. I know what I'm talking about here is primarily theoretical, but as someone who doesn't know much about aspect ratios (or notches), how can I ensure my game works consistently on this range of devices? |

0 | Unwanted rotations with transform.RotateAround I didn't tough i would have issues with this, but unfortunatly I did. I have a Character (which is more a pile of cube) with a body, a empty GameObject for each leg attached to the body with a join and 2 cubes for leg too. The body and the two empty gameobject are child of a Empty gamebject. The 2 cube that represent leg are both child of one of the empty gameObject. What I want to achieve is to rotate the leg around the position of its empty parent by doing this if(Input.GetKey("l")) l leg.transform.RotateAround(l leg.transform.parent.transform.position, new Vector3(1,0,0), 75 Time.deltaTime) unfortunatly, I only want it to rotate on x, but all of the axis are changing, which lead to unwanted rotation. Now, I know rotations aren't independant like translations, but I don't know how to fix this. If possible, i'd prefer to rotate locked joint via script but I have now idea how, I haven't seen anything about it when I looked up 2 |
0 | Understanding pixel art in Unity 2d I am struggling to understand the basics behind pixel art in Unity. I understand what a unit is, and that if I draw my sprite with 16x16 pixels, I should set PPU to 16. Take stardew valley for example, in the image below you can clearly see that the player is not square. The creator of the game said he made everything in 16x16, but then how is there so much detail in the characters? Surely you do not patch several 16x16 squares together to make a character (as you would with a tilemap)? What is the "common" way of dealing with things that are not square, like the characters in the image. Do you just make 16x32 sprite and set PPU to 16? Wont that make it look a bit weird next to 16x16 sprites? Do you generally pick one size (i.e 16, 32, 64) And then stick to that for everything in the game? The visual Issue I've seen is this, where a 32x32 sprite looks very out of place (too sharp) next to a 16x16 sprite. So I am wondering, how do you mix sizes wihout getting this effect where one image looks much sharper than the other. If I for example wanted a character to be 16x32, or any non square value, when my tiles are 16x16 |

0 | How do I switch between different Update behaviour states in Unity? I have a bird entity that needs different update rules when it's moving or dying (among potentially other states). I want to avoid making my Update method a clutter of if else branches like this void Update() if(state movingState) Do moving logic. else if(state dyingState) Do dying logic. else if... Instead, I thought I could make a base class for all my bird behaviours, then derive classes for each state with their own update functions, and use the appropriate derived version based on the current state. public class BirdBaseModel MonoBehaviour void Update() ... public class BirdMoving BirdBaseModel void Update() ... public class BirdDying BirdBaseModel void Update() ... My BirdBaseModel is attached to the bird game object. Based on game states, I want to dynamically reference it in the GameController class. BirdBaseModel b if(State 1) b new BirdMoving() else if(State 2) b new BirdDying() Based on the above logic, I want to call the Update function of that particular class. How do I invoke the Update of the subclass? |

0 | Changing coordinates of the object with velocity preservation In Doodle jump, if a player jumps over one side of the screen he appears on another side with preserved velocity and other physical parameters.

0 | I'm having resolution issues does my math suck? There are a lot of scripts involved so I'm just going to give a generalized description of the process. First, a 1x1 square tile is created. Second, that tile is placed out of the way, and 16 x 10 (160) new tiles are created starting at the (0,0) position and building outward in positive numbers. Now, the camera is a 16 10 display. At this point, I wanted to scale up the tiles. If I want to scale the map up I start by scaling the camera by 100, and then I scale the tiles, and align their position (edge to edge). At this point, scaling the tiles by 100 seems logical, but that didn't work correctly, for some reason. Scaling by 50 almost works, but the resolution is no longer a 16 10 grid like it was before the scaling. What am I doing wrong? I am using Unity. |

0 | Dragging a Rigidbody2D without passing through obstacles I have this body of code written for an object that needs to be an obstacle and another object that is draggable. I have colliders on both and a kinematic rigidbody on the draggable object, but the obstacle is still allowing the dragged object to be dragged through it. This is all 2d. I'm not sure what I'm doing wrong. The part that I'm confused on is this when you just add a collider to the obstacle sprite and a collider and rigidbody (all 2d) to the draggable sprite, if I don't add the script above, then the draggable sprite falls due to gravity on top of the obstacle and stop there, it doesn't fall through the obstacle sprite. However when I add the above script which has the OnMouseDrag function, and I move the draggable sprite around because now I can, it falls through the sprite.

0 | Unity Check if sprite is within range around player I need to know if a sprite is within range (circle or square doesn't matter) around the player. If the sprite is, let's say, 100 blocks away from the player, I will disable it. This wouldn't be too much of an issue, just compare positions and you're done. However, my game is a tile based game and I want the world to be as big as possible, which will result in millions of sprites. I could also add a overlapcicle2D, but the problem is this these objects can't have a collider, since they could be walkable. So how can I check if the millions of sprites are in range of the player, without lowering performance? Alternatively, I could add occlusion culling. But how do you do this with sprites? |
0 | Limit a scrollbar's OnValueChanged to full step intervals only So I have done some research on the matter but I can't find anything.

The values of the steps should go step 1 0.1(1),step 2 0.2(2) etc.I need to get these values and nothing in between or the step that the handle is currently on. How can I do that ? |

0 | Black screen when building apk Unity Alright, I have a bit of a confession to make I accidentally posted this question in the wrong place Stack Overflow. Whoops. Anyway, here's my problem. Sorry if you've seen this before. Here's the original post. I've been struggling with this issue for a few days now. Windows builds for my game work fine, but when I build it to Android, it loads, shows the "made with Unity" screen, then fades to black. Now, I know the next scene (an animated logo) is running because it is playing the audio in real time. However, nothing in the scene is visible. Then, the UI for the in game loading screen appears. Normally, the game would then load, and it does, but again, the camera thinks there are no sprites in the scene. I can still play the game, and the audio sounds just normal, but I can't see. Then, when I die, the game over UI appears, and I can use it as normal. The shop menu works absolutely fine, but the game itself does not. It's as if Unity decided that all SpriteRenderers in the game just didn't exist, and that the camera background color was now black. There are no scripts or animations causing this directly, as it does work in editor and on a PC build. The game also works fine using Unity remote, but the build has the issue. I also made sure that none of the textures were too large for Android (to the point where not one of them is larger than 256x256, which looks terrible but proves a point). Now, before anyone asks, yes, I have seen the other question on this topic, and no, sadly, it did not help. My camera is set to "solid color", not "don't clear." I tried "skybox" too, just to be safe. I have also tried disabling post processing, hoping that Android was just unable to handle it. It did nothing. I have even tried entirely disabling all of the sprites in the scene, but even then, the background is still black, indicating that the camera is still not playing nice. Also, here is a screenshot showing the quality settings for the Android build. |
0 | Resolving this kind of situation in my platformer (movement on slope with roof) I'm building a simple 2D character controller based on raycasts. At this moment I'm trying to finish the player ground interaction. For the ground I will be using edge colliders and no tiling information. I have most code working but there's something I don't really know how to fix. Here is an screenshot explaining the situation As you can see, Player (purple rectangle) is on a slope. When player wants to move right the new x and y coords are calculated to set the player feet again on the slope (Blue rectangle). But, after this response has been applied to the player to make it out of the slope, It is pushed through the roof and some part of it is sticking out the edge collider (red box). How do you handle this situation? On the other hand, If there's any way to accomplish this in a simpler fashion I'm all ears ). Cheers. |
0 | Unity Shader Material Only Activates when Clicked I am currently programmatically settings some shader textures, related to a Mesh Filter.

0 | NPC daily routines and scene loading I'm making a basic survival RPG in Unity 3d. I'm separating my world into different scenes to save memory but I'm not sure how I'm going to program NPC daily routines. For example, if the player arrives in a town scene in the morning, how do I ensure that the NPCs are working in appropriate places with the appropriate equipment? I suppose I could hard code it so NPCs are in certain places at certain times. Therefore, if the player arrives at 9 00am then all the NPCs will move to their 9 00am places. I'm just wondering if there is a better way of doing it than that. I can see myself needing to write a lot of code to cover all the possibilities so it could get really messy. I was hoping there was some way I could have the NPC routines continue seamlessly in the background but this would be taxing on memory if it's even possible. Any ideas pointers on this issue would be appreciated. |

0 | Make enemy follow player intelligently I was trying to make a script to make my enemy follow my player intelligently (but not too much) and I want to know if there was a better way to do it (of course there is but I wanted to find a way myself) Here is what I did I wanted my enemy to detect the player when he approach a certain distance from him. I have a varibale to determine what distance the nemy have to back up (when player is too close) and when it has to follow the player (player too far). Now, I didn't wanted the enemy to just forgot there is an intruder when the player goes around a corner and they can't see him. When the enemy sees the player directly (raycast), they rotate toward him and start following him directly by normalizing the difference of their 2 position. Now is the tricky part i'm not sure about. My player has a list that keeps the 1000 last positions of my player and that update every 0.01 second to add the lastest position and remove the oldest. If the enemy can't see the player directly (!raycast) he goes through all the positions in the list by checking for every Vector3 1 is there something between the enemy and this position ? 2 is there something between this position and the player ? Then it add up the distance between the enemy and the point and the distance between the point and the player and checks 3 is the lenght of the path by going at this point shorter than the last shortest path ? if it's smaller, it's assigne to the best point. If it detected a point that matches these conditions, it goes at it and if it doesn't see the player, it continues checking for new points. If no point matches the condition, he just stop following the player (the enemy lost him). All this works with raycasting to check positions, presence of objects between enemy, player and points and path to go. |

In my game the player can fly to multiple spheres, I want to make it so that when the player gets within a certain distance of the sphere, (maybe using a bigger is trigger sphere collider around it?) their feet will stay pointing towards the sphere until they leave the radius, (maybe using a quaternion?) then if they get within the radius of a different sphere, their feet will point towards that too. How can I make this work? I don't know too much about c , so any example code would help a lot too! |
0 | How people get their game ideas? One thing that always stop me when I want to start making a game is having no idea what to do. How do people get ideas for their game ? I mean realistic ideas for people who are alone with the minimum ressources (no money for assets, blender and unity). I will never stop being impressed by all new concept, mecanics or crazy ideas of game indie developpers come up with, like making game out of random everyday objects. I wish I was able to do that. Do developpers get their inspiration by looking at other games and trying to mix them or change the concept ? Do they look outside trying to come up with what they wish was a game ? Or do they simply walk around and try to imagine a game with whatever they see or reallife situations or concept ? |

0 | How do I transform from local points to world when using a scroll view? I'm using a scroll view to store my game character icons (basically an RPG). The movement system for the characters is tile based, but in game hazards could be located anywhere. So I need to detect if a certain tile will interset with a hazard if a character moves into it. To do this I can calculate the corners of the tile using the co ordinate system of the scroll view. I thought I could turn these into world co ordinates then query to see if the collider attached to the hazard contains the point (the collider could be rotated so I can't just do the math myself). When I try to convert the co ordinates into world co ordinates though the numbers I get just don't match up. For example, the lower left corner of the tile a character will move into is at ( 1250.0, 938.0). If I convert that to world co ordinates I get ( 28.7, 49.8). The actual position for the hazard I'm testing against has a world position of ( 8.0, 1.5, 93.4) though and the test tile should be right on top of it. I'm using code like this to try to get the world co ordinates Vector2 charPosition5 travellingCharacter.owningGameObject.GetComponent lt RectTransform gt ().transform.TransformPoint(travellingCharacter.GetComponent lt RectTransform gt ().anchorMax) Vector2 charPosition6 travellingCharacter.GetComponent lt RectTransform gt ().transform.TransformPoint(travellingCharacter.owningGameObject.GetComponent lt RectTransform gt ().anchorMin) Can someone tell me what values I should be feeding in or what other function I should be using please? |
0 | How to create inline glow shader for 2d polygon in CG using Unity Shader Lab? So here is what I am trying to do. Given irregular polygon (on the left) I would like to be able to create a shader that would resemble Photoshop inline glow effect with opaque fill (on the right). Creating similar effect for 3d object I can achieve with Fresnel function. However, I am not able to do it for a flat surface of any given irregular 2d polygon. EDIT I am planning on using Voronoi method to generate polygons and then connecting individual polygons to territory shapes based on which player owns them. Which, then will have border material applied. What I need is effectively border (or territory) shader. That means shader has to work for more irregular shapes, like the one below. |
0 | A coroutine to rotate one point around another by a given angle without referring to game object I need to rotate a point around another point (in 2D) by a given angle over a given duration, independent of game object (meaning that I've manually created the points and they're not positions from a game objects transform ) as shown in the image below where point B rotates to C by and angle e around A by with radius AB. Using a coroutine would be preferable. UPDATE Based on links provided by MichaelHouse I wrote the following methods to rotate a control point over time by a certain angle but it rather moves to a point (which is not the desired point) immediately to another point, not by the right angle. I'm not sure what I've done wrong. public static Vector3 RotatePointAroundPivot(Vector3 point, Vector3 pivot, Quaternion angle) return angle (point pivot) pivot IEnumerator RotateControlPointWithDuration(Vector3 point, Vector3 pivot, float duration, float angle) float currentTime 0.0f float ourTimeDelta 0 ourTimeDelta Time.deltaTime float angleDelta angle duration how many degress to rotate in one second while (currentTime lt duration) currentTime Time.deltaTime ourTimeDelta Time.deltaTime Vector3 newPos RotatePointAroundPivot(point, pivot, Quaternion.Euler(0, 0, angleDelta ourTimeDelta)) points 0 new Vector2(newPos.x, newPos.y) yield return null IEnumerator runMovement() yield return new WaitForSeconds(2.0f) Vector3 point new Vector3(points 0 .x, points 0 .y, 0) Vector3 pivot new Vector3(points 3 .x, points 3 .y, 0) StartCoroutine(RotateControlPointWithDuration(point, pivot, 2.0f, 45.0f)) UPDATE 2 I've tried another approach using trig functions, but the point moves erratically before finally arriving at a point that seems to be the right point.

0 | How can I prevent movement from analog joystick "bounce"? I'm working on a top down game where the player can move up down left right. The sprite changes to the corresponding direction, and I have an internal value that tracks the direction the player is facing. The actual movement is handled just by doing rigidbody2D.MovePosition(player.position movement speed Time.deltaTime) and it's working fine. Direction is determined by looking at the absolute values of all 4 axis values and seeing which one is greatest. The problem I'm having is when using an analog joystick on a controller. So, if you suddenly let go of the stick, it has a little "bounce" where it goes past the center, and into the opposite direction. I uploaded a slow motion video of the joystick being released, to show this "bounce." See GIF here I added some logging to the input, and here are some numbers The joystick bounce always ends up being somewhere between lt 0.1 to up to 0.5, for maybe 1 frame in time. What can I do to mitigate the effects of this bounce? It's causing my player to suddenly look in the opposite direction if they suddenly stop moving. I've had these ideas for solutions, but I'd love some advice Increase deadzone to be over 0.5 This seems like an easy fix, but that feels like it's too big of a deadzone. Ignore input if the difference between last frame and current frame is greater than a specific value (maybe 0.5?) Average out input over the last few frames and then move? Seems like it could be buggy though (and feel laggy) |

0 | Idle Walk animation problem and double button input axes I have 2 problems with unity3d. First, I created an animator and attached it to player. In animator I put 2 condition, Speed and Running (first is float, second is boolean). Default Animation is Idle. Then player press W, I want animation to fade from idle to walk and when he stop press the button, I want the animation to fade from walk to idle. Here is my problem. When I press W, he make walk animation, but after it he play half of idle animation and after it he enter again in walk animation. How can I loop the walk animation until he release W? And if he release, even if the animation isn't totally played, I need the animator to make transition to idle. How can I make this "transition"? Then I release W, he just go from walk to idle animation without any transition (and it is a kind of wear). Second, How can I put 2 input buttons on axes? I mean If he press W, there should go vertical axes. When he press W Left Shift, there should go running axes. How can I attach 2 buttons to 1 axes? I am new in unity and I want to figure out how to work with this things. |

0 | TBS Shooter targeting AI I have some experience in developing all sorts of (small) games using Unity3D, I have a few personal game projects and I also work for a small game studio. The only subject in game development that I've avoided at all costs was AI, up until now. My other projects required just basic NPC algorithms, so i can't call that AI. On to my problem I have 2 or more player opponents that have to shoot at each other, taking turns (think of a Worms game). They fire using a ballistic arc, adjusting firing power and gun elevation. The problem is making the CPU player to behave like a human player would, without using firing at random. I have, from other games, and algorithm that computes the angle and projectile velocity required to hit dead on the target, but that would kill the opponent in the first few seconds. So i need a smarter, human like approach fire a trial shot, smartly adjust to improve aim. Also account for wind direction and speed that affect the projectile. After some AI research, I was thinking of using genetic algorithms, but i do not need a perfect solution to my problem (to hit the target in the first round) but rather a constant improving one. Also if the algorithm could be tuned for easy medium hard difficulty would be great. I do not necessarily need a complete solution, but a direction to dig to. |
0 | Increase speed with each enemy destroyed? I need some help with coding this idea "For each Target destroyed, increase the Gunner's speed by (speed variable)". The idea is that the Gunner is automatically moving, and I want it to become more frantic with each target hit. Here's the relevant code I have so far using UnityEngine using System.Collections using System.Collections.Generic void Update () Gunner Move () gives me the error "Assets Scripts MovementPathScript.cs(60,83) error CS0200 Property or indexer System.Array.Length' cannot be assigned to (it is read only)" void Gunner Move() if (GameObject.FindGameObjectsWithTag ("BulletProgressionObject").Length 1) Gunner SpeedIncrease () void Gunner SpeedIncrease() behavior that I'm not sure how to make for the bullets colliding with target's parent object void OnTriggerEnter(Collider other) if (other.gameObject.CompareTag ("BulletProgressionObject")) Destroy (other.gameObject) I think it's a foreach loop, but the issue I'm having is properly implementing it. Any suggestions or referrals would be greatly appreciated. |
