0 | How to rotate an object to a specific transform? I am working on a car racing game and there are some times when the car rotates and ends up on its roof. On those situations I want the car to respawn on the same location. What can I do to rotate it so the car ends up on its wheels? |
0 | Unity Editor Adding Object Fields on button click So I am trying to make a button that will spawn an object field and a float field when clicked. Each object field being unique, so I can add gameobjects to it. I can t think of a way to do this. This is purely Editor Scripting. Also, if there is an option to delete a row (the object field and the FloatField) that would be amazing |
0 | How can I change the speed flag for random or not random at run time? This method is being called by Update() 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 using the changeSpeedOnce flag helper to assign the speed to the followers once either random or the constant speed. but then when the game is running changeSpeedOnce is true and if I want to change the randomSpeed flag again I need somehow somewhere to set the changeSpeedOnce to be false again. I don't want to use a button or an input key for that but using the randomSpeed flag. |
0 | Unity Disable push on dynamic Rigidbody2D objects I have a player, and several NPCs. I also have several static colliders in the world (trees, water, fence, etc), I want my NPCs to collide with this, so the Rigidbody2D needs to be dynamic, since kinematic does not collide with static colliders (colliders without a rigidbody). My problem is that since both player and NPC have dynamic rigidbodies, they push each other when they collide. I could disable this by setting the following in the NPC script void OnCollisionEnter2D(Collision2D other) if (other.gameObject.name "Player") isMoving false myRigidBody.isKinematic true However, the NPC still gets pushed a few pixels before it stops, its barely noticable, but it is noticable, and if you keep colliding with the NPC you could move it as far as you wanted (tedious, but possible). I've spent a few hours looking and cannot find a good solution to this. I want my NPC to collide with static colliders, but I don't want them to get pushed by the player. How can I solve this? |

And i want that when it's true and the door is on locked state to change the color of the two Point light 1 from green to red. In the Start i did if (doorLocked true) for (int i 0 i lt lt.Length i ) lt i .color Color.red When i'm running the game and doorLocked is false this is how it looks like Both lights are green and i selected one of the Point light 1 and you can see in the inspector the Color is green Now this is a screenshot when the game is running and when lockedDoor is true. Now it should be red but it's only red around the Point light 1 the color seems to be still green Now i saw that in the Hierarchy one object above Point light 1 is called Light Small 02 it's a child also of Light Small 02 I marked it here with a black circle. And i think that i need also to change this Light Small 02 color from green to red. Not sure since i can't find any green color with it in the inspector but when i disable the Light Small 02 the green color is gone. Anyway the main goal is to change the color of the two lights according to the door state doorLocked true false This is a screenshot of Light Small 02 inspector showing the mesh renderer part |
0 | Tetris block kinematic rigidbodies pass through one another with Transform.Translate I am trying to build a Tetris 3D game in Unity but I am stuck at getting the different blocks to interact (to detect each other, to sit one on top of the other rather than going through each other). I have set the ground with a box collider and the spwaned blocks come in with rigidbodies and trigger colliders. This works for them to nicely settle on the ground but when I try to sit a block on top of another block they both have kinematic rigidbodies and the collision detection doesn't work and they end up overlapping. The problem is if I remove the rigidbody of the already settled block then it will go through the ground.

0 | Moving directional light cause huge fps drop why? I've implemented a simple script to simulate Sun Rotation (day night cycle). In my "Update" i Rotate main Directional Light (the sun). What i've noticed is that my FPS dropped from 60 to 20 25 fps. I can understand why recalculate all light each frame can be (euphemism) cpu consuming. So i switched approach using an InvokeRepeating with a repeating time of 0.25f seconds (4 "movement" per second). Also with this approach my frame rate drop from 60 to 50 (unacceptable). So my question is is there a way to move rotate a light (simulating a day night cycle for instance) without meet a so big fps dropping but mantaining realism ? Thanks |

0 | Architecture of "doodle jump" type gameplay infinite looping background I am planning make a doodle jump type game, character jumping on platforms. A scrolling or doodle jump like background which ll appear to move when character moves upward and appear moving (just like in doodle jump) so, my thoughts are for this kind of background is to take a large image i.e of 2048x2048, make 2 planes, set this texture to them, when first image ends other ll move its position on top of first, when second ends first ll move on top of second and so on. Other approch could be a "Instantiate" and "Destroy" of small images having textures on them according to jumping character position ( which i doubt ll b expensive ) They are my thoughts, I want to go for best approach and would like to listen the best one. Is there any more appropriae way to achieve moveable background, I ll appreciate your suggestions. Thanks. |
0 | In Unity, what does the camera script's "Behaviour missing" error mean? I started in Unity few days ago and made a cube with a tank control style. Now I'd like to create controls similar to 3D fighting games (Gunz, Blade Symphony, ) Control body direction with the mouse and walk with WASD. However, the Camera is giving me a error called "Behaviour missing" each time I try, with all the cameras scripts I saw. I think that is a error with tagging the character movement in the camera, but I don't know how to do that. What might be the problem? |
0 | How to make a procedural tilemap island with more than one tile in unity? I have been working on a simple survival game. I made the character and some basic elements (I'm new to the field though). But what I could figure out how to make is the world generation. I just wanted to make a program that generates an island procedurally. I tried Perlin Noise before, but it wasn't that efficient. The results were too random. In the past few days, I found a unity package that generates tilemap islands, and I really liked the results, but I didn't know how to make more tiles than just grass. The problem is that I don't know how can I make a script like this because I am still new to unity. That's why I tried asking for some help. I just want something that looks like this I would really appreciate any help! |

0 | How to store and organize my data in a JRPG style game? I am trying to make a JRPG style game using Unity. See this image below to get a sense of the "feel" of the type of game I am making http www.juicygamereviews.com uploads 3 0 5 0 30501048 9185639 orig.jpg Currently I'm struggling to find a good way to organize the data in my game. Referring to the image above, see how each party member has stats, as shown in the UI? I'm sure the monster also has the same kinds of stats, just hidden away. Hence, I want to make a struct called Stats, that both PartyMembers and Monsters contain a reference to. To summarize what I'm saying so far Right now I'm pretty sure I want two classes one called PartyMember and one called Monster, both of them deriving from a common class I'll call it TurnTaker that takes turns during battle. In the TurnTaker class I want a reference to a struct called Stats, which contains HP, MP, Attack, Defense, etc. The problem is, for player data I want the Stat class to be Serializable because I want to save player progress in a binary format, yet for Monsters I wish to make the Stat class inherit from Scriptable Object (SO) for easy development and editing. Is it possible to make Stats both serializable and derive from SO in Unity? (Note a struct cannot derive from SO only a class can. Should I change my stats from a struct to a class? Seems a bit of a waste, just for the inheritance functionality.) Further, I'm thinking party members have data specific to themselves (equipment, total EXP, character class, etc), as do monsters(drop items, movement type, etc.) Should I make these two "things," I'll call them PartyMemberSpecificData and MonsterSpecificData separate classes altogether separate interfaces that attach themselves to PartyMember, Monster, or Stat classes that derive from Stats (I think I want PartyMember to contain a reference to PartyMemberSpecificData and Monster to contain a reference to MonsterSpecificData.) Any help appreciated! |
0 | Is it possible in Unity to Flip a 2D Sprite Without Flipping the Object it is Assigned to? I 'built' (followed a tutorial) on a collision detection system, and when I flip the object to go left and right the collision messes up. So I have three options find a way to modify the collision detection, have sprites for all animations for left and right or to flip the sprite but no the object. if anyone has used RaycastHit2D, and has figured out a way to do it correctly, that would also be great. |
0 | When creating a game, what are some architectural desgin concepts I can use to be able to port my game from single to multiplayer? I am a software developer but, I mostly develop games in Unity. I have experience creating single player games as well as multiplayer games. I am at a crossroads where I am in the middle of development of a proof of concept or small demo and all of a sudden I am asked to turn it into a multiplayer game without prior knowledge of this I turn around and say it would add 50 to development time because I basically have to start over from scratch because I didn't necessarily take into account that later down the road they might want to change the experience from single to multiplayer. So with all of that out of the way, are there any different methodologies out there that would make it easier on the developer to port a game from single player to multiplayer? I have thought of a possible way of doing this by just setting the game up as single player, however, making my functions where they are easily able to wrap them using Commands and RPCs. But I find this may or may not help me and is only dependent on what the requirements are. My biggest time killer when it comes to porting these PoC's is typically the UI. Most of the time my requirements are so that the UI will be the same shared UI for all clients and having to update it for each action performed on it and dealing with handling ClientAuthority. (Any tips for dealing with this would be greatly appreciated too) Think of this as something like, making something with Legos in multiplayer and having shared instructions based on the step the user is on. Summary What are different ways that I can design a small demo concept where I can easily port it to multiplayer later on, or make my game where it is "multiplayer friendly" ? Or should I try to stay away from this type of thinking altogether and just develop a single player aspect and just develop a multiplayer aspect, arguments for and against this concept are sought after. |

0 | Is a 3D renderer with 1000 FPS possible? Okay, for my phD Thesis, I need to make a simple 3D game, like towers of hanoi or whatever but there is a condition I need it to have high FPS, as in, the highest FPS achievable, atleast a 1000FPS. I need to have a high FPS to measure reaction times. We achieve this with 1ms monitors BUT on the programming front, here is the problem, I'm confused if I should code an entire specially made engine with only the features I need (using Vulkan), and if I did would it be faster than already available engines like Unity or Unreal? Would it be worth the time and effort or can these engines be customised themselves and is that easier than doing it from scratch? Or is it only achievable with specialized hardware? So I'd be better of using an available engine and going hard on the hardware? |
0 | How do I find all game objects with particular name? I'm trying to mimic FindGameObjectsWithTag with FindGameObjectsWithName. I know using tags is faster, but I'm trying create a way to search for objects I spawn with a child object I name on instantiation through the inspector. My goal is create multiple enemy spawners. My current spawner has a drag and drop variable for enemy prefabs. It looks for enemies tagged "ReSpawn", then checks if that length is below a value, to start spawning more. I would like to upgrade my current single spawner to still check for enemies named "ReSpawn", but then check if those respawns have a child object a name specified in the editor. This way, I can set the enemy spawners anywhere (e.g. near water, tall grass, forests, etc), and when I defeat one, the specific spawner will instantiate one of its opponents for that area. Here is my code, so far var ThisSpot String var Oppos GameObject var OppoCount GameObject var HowMany 3 var spawnSizeArea 25 function Start() StartCoroutine ("Spawn") function Update () OppoCount GameObject.FindGameObjectsWithTag("Respawn") OppoCount GameObject.FindWithName(ThisSpot) This is what I am trying to achieve if(OppoCount.length lt HowMany) StartCoroutine ("Spawn") function Spawn() var length Oppos.length 1 var index Mathf.Round(length UnityEngine.Random.value) curSpawn Oppos index var xz Random.insideUnitCircle spawnSizeArea var newPosition Vector3(xz.x,0,xz.x) transform.position yield WaitForSeconds(Random.Range(70,120)) Instantiate(curSpawn, newPosition, transform.rotation) Then I could use these 2 lines of code below to use multiple spawners var newOp GameObject Instantiate(curSpawn, newPosition, transform.rotation) newOp.transform.Find("fighter").gameObject.name ThisSpot StopCoroutine("Spawn") |

0 | Closest node in A pathfinding For my 2D Unity game, I've implemented A pathfinding based on waypoints. System already handles building graph from waypoints on scene (which are manually placed objects), as well as finding and caching closest routes. So, general idea is to select closest waypoint to character, closest waypoint to target position, and use pathfinding algorithm to find closest route (which is pre cached already). Yet, I've stumbled into issue I don't know how to actually get closest waypoint. Well, there are several ways I think of, in the worst case I can just brute force closest non blocked waypoint from the collection, but that would be bad performance wise. So, are there any proper ways to get start or end points? |
0 | Unity Trail Renderer artifacts flickering disappearing I have a projectile prefab that have 2 trail renderers attached to it. Whenever I instantiate another projectile, every trail renderer seems to flicker. This is similar to the question Changes to one Unity trail renderer causes all of them to flicker In addition to that, I have other rendering artifacts as well. Having too many trail renderers seems to cause some of them to not draw. Also, sometimes, they just seem to randomly choose not to draw. As you can see, the left most projectile doesnt want to draw its trail. Similarly, adding more projectiles, the front projectiles seems to lose all of its trails. So thus, the 2 issues I am having is Flicking trail renderers when another is instantiated. Trails not rendering randomly. Unity Version 5.3.2f1 |

0 | Screen Capture rendered on a RenderTexture in Unity I have a pretty wild idea for a unity application that would work on a multi display setup. The app would be running in full screen mode on one of my displays, and the contents of the remaining two displays should be rendered in game on a texture. I've seen RTMP clients for unity and I've tried streaming my desktop with OBS to a local RTMP server but the delay was too big (more than 5 seconds). I would prefer an instant (or very low delay) solution for mirroring my displays on textures in Unity. If anyone can help me solve this, i would appreciate it! |
0 | Unity protect MonoBehaviour derived classes from instantiating via new in C When the class hierarchy grows and you deal with a lot of custom types in your project, it sometimes becomes hard to remember which types are allowed to be created via new and which types are derived from MonoBehaviour and therefore can't be created via new but must instead be attached to the GameObject as a Component. Is it possible to have some safety mechanism for this? The goal would be to have two base classes to control the ability to use new on a certain type. Ideally resulting in a compile time error instead of an easy to miss warning in the console ("You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. Blah blah."). My attempt to make the constructor protected, like this public class UnCreatableBase MonoBehaviour protected UnCreatableBase() using new should be not allowed public static T Create lt T gt () instead this method allows object creation return GameObject.Instantiate (Resources.Load ("Prefabs " typeof(T).Name) as GameObject).GetComponent lt T gt () public class CreatableBase public CreatableBase() new is ok here still allows me to write var whyDoesThisWork new UnCreatableBase() I can access the protected constructor even from an outside scope. Now, the obvious solution would be to make constructors of MonoBehaviour derived classes private. Manually. All of them. Manually. I was wondering if there's a way of achieving the same in a more generic way. |

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 to calculate FPS and what factors affect FPS? In this case, FPS means Frames Per Second and that means the number of frames that graphic hardware render in one second. I'm wondering what kind of stuffs could affect FPS? So, for some tests I created a simple scene in Unity with some cubes and capsules and then create a empty game object and then add this c code to it public class FPSReport MonoBehaviour public double Fps void Update () Fps 1.0 Time.deltaTime I think it can tell me the FPS. When I played it it worked but it wasn't more than 30. I was saw a lot of games that their fps was normally on 150. Is this fps rate ok? If I add more objects, textures, animations , etc ... to my scene. What happen to my fps? Could it attain zero? and If it attain zero, what is the meaning of a zero FPS (the hardware stopped working?!)? |

0 | Alternative solutions to applying an overly large and detailed texture to a mesh I have a very large spherical mesh in my Unity scene (the earth), to which one very large texture is applied (a map of the earth). Now it just so happens that Unity's max texture size (8192 pixels I believe) is not enough to capture the details I need on this huge mesh. What's the proper way to deal with this situation in Unity? That is, not only overriding the 8192 pixels limitations (although that would be nice as a temporary solution), but also making sure the overhead won't become unbearable... Is there a way to dynamically stream higher quality sections of textures as the camera gets closer to that specific part of the mesh? Additionally, I see the Granite add on (http graphinesoftware.com products granite for unity) seems to do just this (if I understood it well), but it's only for Windows, and I'm developing on a Mac. Is there any other adding out there? |
0 | How to know which child collider triggered in parent? I have parent object with 3 children. Each children has one collider (BoxColliders actually) marked as triggers each one. I want to know in a OnTriggerEnter on the parent side which collider was hit. Similar to this question How can I determine which Trigger is hit? But for 3D Colliders (not 2d). As you can see in the accepted answer they used Collider2D.IsTouching but it doesn't seem to exist any analogue method for a 3D Collider If is not possible, what other solutions are there? What would be the recommended way? I would like to avoid the overhead from methods like CompareTag and SendMessage if possible. http answers.unity.com answers 1206114 view.html |

0 | Raycasting from an object to the center of the screen (crosshair) without clipping through objects Am trying to learn about Raycasting, and I thought I would start with something simple, and that was a laser that would come out of an object (think laser pointer in your hand) and always go to the crosshair. Using ViewportToWorldPoint I found it easy to cast a ray from the center of the camera, but this had an issue as you can see in this GIF below. The line would clip through because the ray was coming from the center, not off to the side where the laser pointer would be. Am not sure how to solve this. void Update() Vector3 ray Camera.main.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, 0f)) line.SetPosition(0, transform.position) RaycastHit hit if(Physics.Raycast(ray, Camera.main.transform.forward, out hit, raylength)) if(hit.collider ! null) line.SetPosition(1, hit.point) else Vector3 pos line.GetPosition(0) line.SetPosition(1, ray (Camera.main.transform.forward raylength)) The closest thing I could find that I am trying to replicate for this exercise is the No Man's Sky mining tool |
0 | Lower WebCamTexture dimension without requesting Handling image with high resolution dimension can cause heavy lag in low spec computer . So i need to lower the dimension of the image to make it less lag for processing . I know i can do it with WebCamTexture.request(width height) , but if the camera does not support low dimension image , the result image dimension will be still big . I've tried to convert it to Texture2D using WebCamTexture.GetPixels() and uses lower width and height for the Texture2D , but it breaks the image and the result was unexpected . I also have tried to set the WebCamTexture to an object , and get that object captured by in game camera , and resize the image that was captured by the camera , but then it means the high dimension image is doubled (WebCamTexture and image from the in game Camera) and doubled the lag than just using WebCamTexture . Can anyone here help me please ? i will upvote for any attempt to help . |

0 | Everything is set to Bounciness 0 Why am I still bouncing? I am creating a platformer where rather than manipulating the character to get them from the beginning of the level to the end, you manipulate the world. Thus, when you want to make the character 'jump' over a gap, you actually use the land like a slingshot and 'fling' them. This is all working well and good save for one thing whenever I pull my land down and my player falls into it again, it begins to bounce aggressively so! I have made EVERYTHING out of a new physics material with 0 bounce, and I set my default physics to 0 bounce. My player is a rigidbody2D that is moving itself along on top of other rigid bodies. What gives? Why, even though EVERYTHING is set to 'no bouncing allowed' does my game turn into a bouncy house whenever i start to play? EDIT Here is a video of the behavior FlingyJump Bouncing Issues EDIT I have noticed a correlation to the bounce occurring and the spring being active. It have noticed that two things are happening 1) The spring is for some reason transferring force through to the ground piece while being stretched out. 2) The player is bouncing before even ever hitting the ground. I don't know quite how that is possible but it seems like as soon as it is enters the original position of the rigidbody2D for the ground piece it bounces. |

0 | Does Animator.SetBool take precedence over Animator.SetTrigger in Unity's Animator? I've got an Animator with transitions from Idle to Walk or Dash. Walk requires isGrounded to be true and a float MoveX to be greater than .2. The Dash animation requires Dash trigger is returned. In my code, when the shift key is pressed I call anim.SetTrigger("Dash"), if a Walk key is pressed, I set anim.SetBool("Idle") to false and begin increasing MoveX. The problem I'm noticing is that when I play, and hit the dash button, it first starts walking and then after playing that animation it will then perform the dash animation. Looking in the animator as this is happening, it's clear that the walk animation plays in full before moving to the dash animation. What can I do to give priority to the Dash animation when that button is pressed? |

0 | Deleting fewest Navmesh Obstacles when no valid path is found So I'm building a Tower Defence, with mazing (i.e. the player can place towers to make the mobs take a longer route to there destination.) I'm using Unity's Navmesh system. Each Enemy unit has a Navmesh Agent component. And each Tower has a Navmesh Obstacle component. The Path finding is working Perfectly. However (as expected) when the play completely blocks off all routes to the Agent's Destination, the agent simply moves to the spot closest to the destination that it can get to and sits there. What i need, is to detect when that happens... Some kindof NoValidRoute() or something, I haven't been able to dig anything up in the Unity documentation or from google Searches. Once i have that, I need to determin which Navmesh Obstacles need to be destroyed to open the shortest route possible with the fewest number of Obstacles destroyed. (i.e. if a path can be opened with only 1 tower destroyed which tower would give me the shortest route.) I'm finding a serious lack of any information on this subject.. as far as i can tell no one has even tried to do this, or asked for help doing something like this. (at least not with Unity's Nevmesh.) I think A is a little(and by little i Mean LOTS) outside of my skill to implement at present. Thanks In advance |

0 | Bright lights produce strange artifacts on Android I'm testing lighting on Android and I'm getting strange artifacts when the light is increased. I'm not sure if this is normal with Unity or a setting somewhere is unchecked. The only light in my scene is a spot light. I have to increase the brightness of it so that it illuminates everything in the scene properly. On Windows 10 (in the editor), it displays just fine. You can turn the brightness up all day long and everything will just appear whiter. On Android, however, once you reach a certain threshold (a really low threshold), the colors turn to an abrupt magenta, then dark cyan, and eventually black. Because I'm using a spot light, these colors appear as a radial gradient. Here's what I've tried so far Turning the brightness down. Unfortunately, I have to decrease it a lot to avoid the artifacts meaning my scene doesn't get illuminated in the way that I need it to be. Changing Lightmapper from Enlighten to Progressive in the Lighting window. But what I think this actually indicates is compression and so is unrelated. Not specifying a Skybox material and using Custom environment reflections. Tweaking Graphic settings for each tier (I have double checked HDR is enabled both here and on the camera present in each scene). Switching to Linear color space (I was originally using Gamma). The idea was maybe the color space was too small so really, really bright colors couldn't be represented however, it is my understanding that Gamma is much larger than Linear so I'm admittedly confused. I have Googled this issue quite a bit and all I get are issues with emissive materials not emitting light and other unrelated light issues. Here is what my scene looks like when a spot light faces a rectangular mesh. When the threshold is exceed initially, it looks like this If you continue to increase the Intensity, it eventually looks like this Of course, the exact colors you see vary based on the actual color of the mesh being illuminated. In the pictures above, the mesh is supposed to be a medium dark green. Could this be a color space issue? Perhaps a device limitation? My device isn't exactly a super computer, but it isn't bottom grade either. |
