0 | Convert the animation inside FBX into Unity Recently i bought a package with an fbx and lots of animations. Since I want full control and change a couple of details, I want to convert them into the regular Unities Animation System. I cant convert them into the normal Unity Animations though. They are "read only". I can load them, copy paste them into my own "not read only" animation file. But somehow i cant change the file anymore after I pasted something inside. What am I doing wrong? Is that something "impossible"? Can you guys help? |
0 | Make objects stack in unity? I have two kinematic rigidbody cubes from the standard 3D objects, I have also enabled contact pairs mode to quot all contact pairs quot , how do I make it so that no matter what angle they collide in they perserve the same angle but just get out of each others space making it look like they're in contact e.g. collided? Here is my attempt at doing that using System.Collections using System.Collections.Generic using UnityEngine public class Physics MonoBehaviour private Collider collider1 private bool grounded false used to determine if the collider hit something so it doesnt keep going down Start is called before the first frame update void Start() collider1 GetComponent lt Collider gt () Update is called once per frame void Update() if (!grounded) if the collider hit something, stop going down collider1.transform.Translate(0f, .1f,0f,Space.World) private void OnCollisionEnter(Collision collision) grounded true the collider hit something if(collider1.transform.position.y ! collider1.bounds.extents.y) if this is true, it means it is at the floor so dont move it transform.position new Vector3(collider1.transform.position.x, collision.collider.bounds.size.y collider1.bounds.extents.y, collider1.transform.position.z) attempts to put the collider on top of whatever it get This works if the cubes are right on top of each other with no angle It also works if one of the cubes collides at a angle to the other cube, when they collide the bottom cube perverse its angle of collision and and the top cube just gets out of the space of the other collider making it look like they have collided What doesn't seem to work is if both cubes collide with each other at a angle, although they preserve their angle of collision, and also get out of each others space, they do not remain in contact with each other which if they did would make it look like they have collided. Instead there is a gap between them, how do I get rid of the gap e.g. make it so that no matter what angle the objects are at they get out of each others space, preserve the angle, and remain in contact with each other to give the illusion that they have collided? |

0 | Manipulating an animation towards a target object (ie. The hand and arm lean towards the target) I am trying to make a boxing game just for fun (I dont expect the end product to be anything decent lol) . I have my boxers in the ring and they are animated quite well so far, with Idle, and punch Left and Right. They also rotate so they are always looking at each other. What I want to do is give the punch some aim towards the head. I will give the punch a set amount which it can move from the standard animation and move the hand bone in the direction of the targets head object. But I don't know how to do this S So far i have used dragged the 3 animation files into Mecanim and coded it to do the animations when a button is pressed. Is there a way to manipulate the animation in this way? (ie. actually make the arm reach towards the target object ) |
0 | Unity look at rotation on one axis only problem Hey I would like an object to look at another object only at one axis, when I rotate the white cube all around the gray cube (gray has look at script), the gray cube flips as soon as the target passes the middle and is on the right side. How can I fix this, so that rotation is normal. Below is when the cube (target, white).

0 | Ocean visible through the island's lake in Unity3D? I'm working on a puzzle game featuring islands there is a plane with a water shader, and objects colliding with that plane. Now I'd like to make lakes on the islands, with different (higher) water levels than the ocean's. The problem is that if I put a water plane in a "hole", I can see the ocean below at best, or even worse, the upper water surface just glitches out and disappear. One option is that I move the lake's basin higher than the ocean's see level. This works, but I it doesn't look so good, because the lake becomes too shallow. Another option is that I cut holes in the ocean's plane, but that seems a bit overengineered, isn't it? Is there a better solution? Also having a water plane for every "lake tile" causes some problems but I want to have dynamic lakes, so having a 2x2 water plane for a 2x2 group of lake tiles isn't a walkable path. |

0 | Best way make static GameObject clickable 2D I've built a turn based battle combat game (like pokemon) but i'm stuck between a rock and a hard place. Asfar as i understod UI elements should be inside Canvas, while Players, Enemies, Items and etc... Should not be inside a canvas. Correct me if i'm wrong. I've tried different ways how to handle this situation. Such as make Enemy as a button, but seems not to fire. Since i think it has to be inside a canvas. Also make enemy which have animations as button, may not be a good idea? Update event, to check if the mouse is down and mouse position is converted with screentoworldpoint and see if the positions matches with the enemy position. Update event, to check if the mouse is down and rayCast see if we colide with something. But i dont feel like this is neccesary since the enemy does not move. So the position is always the same. Also if it's possible to take into consideration that every enemy is different size. But this is a minor detail, i would like firstly tackle the best way handle onClick event without the extra overhead. I would appericate any feedback on my dilemma. |
0 | One rock gameobject drops FPS heavily! Okay so this is really odd I have a game object (a rock) that even though is really high detail drops my fps from around 70 steady to 12! Now the object is divided into LOD's and the closer I get to the object the worse it gets! I have created a Material for each LOD of the object where i replace the normal map with a lower LOD (The other channels stay the same). The import settings for the different LODS looks like this Now as of the textures they are set to 2k (all of them) Can anyone tell me why this is happening? The object itself looks like this inside the game Even my scene view has framerate issues when looking at it. |
0 | Use arrow keys to navigate between specific toggles, not all UI elements I'm making a game where the player needs to select a object out of three and navigates between then with the arrows of the keyboard, and I'm using toggles to make this system. But the problem is that when I hit play, the navigation mixes the toggles with some other UI elements I dont want to include in the navigation, like sliders and buttons. How can I lock the navigation for just these three toggles? I also want to make the navigation switch between these toggles and another three toggles in the middle of the game. How would I change my navigation via script? |

0 | For creating a distant moon in a 3D game, is it better to use a model or texture? I'm working on my indie game and I want to create a moon (it's a 3D game) however I am unsure if I should create a model and put it far away, or if I should use a texture on a plane and have it constantly move so the face of the plane is facing the player. The problem I had last time I tried a model is the render view, as the model was really far away (as when I did it very small, you could sort of tell it was a tiny model rather then a far away moon) and with the texture I'm not sure if it comes across as tacky. I'd really like to hear the pros and cons of each, since I'm planning to use the 'render objects only when in view' method and basically want advice on which I should go with. |

0 | How can I efficiently make a solid Texture2D? I am trying to programmatically make an Image to cover the entire screen. I create the Texture2D, then create a Sprite from the Texture2D, then apply the Sprite to my Image. This works, but it is slow.

0 | Unity3d zooming with orthogonal camera like in Google maps I am implementing 2d orthogonal zoom. As far as I know in Unity3d there are no translations like in OpenGL. Taking this into consideration, I work with camera size camera position (center) real world mouse position I have no issues implementing simple zoom in zoom out operations, combined with camera position changes ( drag'n'drop ) But I have some issues calculating camera zoom shift in this case camera size (4,4) camera position (0,0) real world mouse position (1,0) A double zoom in (2x) is applied, as a result camera size (2,2) camera position (0.5,0) real world mouse position (1,0) User shifts real mouse position to (1.5,0) and applies a double zoom out ( 0.5 ). In this case camera size is again (4,4) camera position ??????? real world mouse position (1.5,0) What should be the camera shift so the mouse doesn't visually move ? What is the formula for calculation in this case ? Thank you in advance. P.S. Any suggestion regarding current method of handling zoom are welcome Update So I resolved this issue with Blue's help. The basic idea about shifting is right. The main reason it didn't work was incorrect zoom factor. Example Initial camera size is 5. User zooms in by 1, camera size is now 4 ( it displays less content on the same 'screen'). User changes mouse position and zooms out by 1. Camera size is 5 again, but the amount of zoom is actually different initially the change was 20 ( 1 5 ) in the second time, the change was 25 ( 1 4 ) My fault was that, when zooming out, I tried to restore position by 20 , not 25 . |

0 | Unity animation transition with 0 Exit Time doesn't transition immediately Question Why doesn't an animation transition with an Exit Time of 0 immediately transition to the next state? Minimal example Using Unity 2018.3, I set up an AnimatorController with two states Initial and Next. I wanted Initial to transition to Next immediately, so I tried setting an Exit Time of 0. However, this doesn't transition immediately As shown above, Initial state still runs instead of transitioning immediately to the Next state. (There is no Motion attached to the AnimationState, so perhaps it's using a default duration.) Below are screenshots of my animation transition settings. Strange behaviour with small non zero ExitTime I also tried using an Exit Time of 0.01 (i.e. transition after 1 of the animation has played), and it transitions almost immediately as I expect most of the time. However, occasionally it will still play the Initial state In this case, even though it transitions to Next immediately most of the time, it still occasionally waits for the Initial state to complete. (It happens much less frequently than the image above suggests, but the issue becomes more frequent if I set the ExitTime even lower, e.g. 0.003). Workaround From searching online, the recommended solution for immediate animation transitions seems to be to turn off Exit Time and use a condition (e.g. bool or trigger) to transition immediately instead. (Edit in my case, I've defined an animator bool parameter called ImmediateTransition and set it to true by default instead of using Exit Time 0.) This seems to work, but I would like to better understand how Exit Time works and why it's not working the way I expect. |
0 | Align spawned particle system I am working on a game in which tanks can shoot at each other. I intend to spawn a spark particle system (particles emit to Z) when a bullet hits a surface. I want to align the Z axis of the newly spawned particle system to be a) in a 90 degree angle to surface that has been hit b) in a reflective angle from the original trajectory I know that I can "fake it" by setting particle Z to World 90 degrees, however then it will do so on any angled surface, while I would like to have the particle system dynamically orient itself in a 90 degree angle away from the surface that has been hit or reflect into the direction away from the incoming bullet. hope you can help me, getting quite frustrated. |
0 | What is the most appropriate way to achieve synchronous Addressable asset loading? I am transitioning my project from Resources to Addressables. Some parts of my game just aren't worth doing asynchronously, and would just cause more problems but I still want to use Addressables for its other benefits. Anyway, it doesn't offer any synchronous methods in their API. Unity has an official repository with an example for "synchronous addressables" right here https github.com Unity Technologies Addressables Sample blob master Advanced Sync 20Addressables Assets SyncAddressables SyncAddressables.cs Although the code does appear to work in the few tests I've done The code below won't always work, and it doesn't make sense to me anyway. This is the relevant method public static TObject LoadAsset lt TObject gt (object key) if(!s Initialized) throw new Exception("Whoa there friend! We haven't init'd yet!") var op Addressables.LoadAssetAsync lt TObject gt (key) if(!op.IsDone) throw new Exception("Sync LoadAsset failed to load in a sync way! " key) if (op.Result null) var message "Sync LoadAsset has null result " key if (op.OperationException ! null) message " Exception " op.OperationException throw new Exception(message) return op.Result It will throw an exception if the asset didn't manage to load instantly (the !op.isDone part). Sure, that's technically synchronous, but it seems to ignore the elephant in the room if the asset is large I would expect it to need a bit more time (i.e. freeze the game), which is fine for my current needs but instead, the game will just end up crashing because it couldn't load immediately. What is the most appropriate way to achieve synchronous Addressable asset loading? |

I want to check the space where I want to place a room, in this case up for if there's already a room there. I've written this code to do that but it doesn't appear to be working.

0 | How to edit key value pairs (like a Dictionary) in Unity's inspector? I have a spell system I am creating, the principle is as follows Each spell is an autonomous prefab.

0 | Unity Transport Layer API How to manage client server connections I am currently working on a "Master server" system for our Unity Game using Unity's Low Level "Transport layer API" for networking. My problem is that I would like to prevent clients from connecting to eachother. I have tried not giving them a port on the Addhost() call, but it doesn't seem to change anything. They also do not seem to detect the connections, so basically I find myself with NetworkTransport.Connect(..) calls that work (the error byte is 0, meaning no error) but no actual connections. I don't understand what's going on. I can't really show my code because it's quite long, but here's how it works, in summary The Clients objects initialise a Socket as normal with only one Reliable channel, no port, and one connection allowed by default. Then they have the ability to connect to another socket, as you'd expect. My problem COULD be coming from there for testing purposes the IP I use for testing is 127.0.0.1. What I do not understand is, how can it "find itself" when it is not bound to any port ? And more importantly how can it NOT find the Master Server object whose socket IS bound to a port ? Speaking about Master Server, it's an object that also initialises its socket, but with a port and many allowed connections. When a client connects and the connection did not yield any errors, it considers the connection to the Master server to be successful and proceeds sending a message containing some information for the server about this client the username chosen by the player for example. When the master server receives a connection event, it registers the received ConnectionID and waits for more information from that same connection, for example the aforementioned username. Both the client and the server handle receiving messages with the NetworkListener class (Static). On each frame it executes the Listen() method which executes a "normal" NetworkTransport.Receive() body. I can give you that part of the code as it is fairly common in design public static void Listen() int recHostID int recConnectionID int recChannelID byte buffer new byte 1024 int recDataSize byte error NetworkEventType e NetworkTransport.Receive(out recHostID, out recConnectionID, out recChannelID, buffer, 1024, out recDataSize, out error) Debug.Log("Listening") switch(e) case (NetworkEventType.Nothing) break case (NetworkEventType.ConnectEvent) Debug.Log("Connection established. ConnectionID " recConnectionID) if (OnConnectionReceived ! null) OnConnectionReceived(recHostID, recConnectionID, recChannelID) break case (NetworkEventType.DataEvent) Debug.Log("Received data !") BinaryFormatter f new BinaryFormatter() MemoryStream stream new MemoryStream(buffer) Message f.Deserialize(stream) as NetworkMessage break case (NetworkEventType.DisconnectEvent) Debug.Log("Connection terminated. ConnectionID " recConnectionID) break Network message is a simple data structure which contains a ConnectionID (the one it's from), a message title and content. The title is used to determine the general purpose of the message. The content is the rest of the information. What happens in my current build of the client The user is prompted to enter a username, then he clicks "Search for match". The search for match button is supposed to trigger the connection to the Master Server. The logs say that the connection was successful (as no errors are detected) but no Connection event is received on either side. This of course prevents everything else from working. If you need further description of the problem just ask and I'll answer ASAP. Thanks a lot in advance ! |
0 | Season Change Reveal Effect I was watching the teaser trailer for Seasons After Fall, and I was struck by the effect they use to transition between seasons (around 21 24 seconds) The level art, including the background and the foreground platforms, change from a sepia coloured autumn to a lavender winter, with the effect spreading outward from the player character a bit like water soaking through paper. It looks like more than just a palette change, as details in the leaf and bark patterns change in the transition. How could I achieve an effect similar to this in a 2D Unity game? |

0 | Blend Tree animation problems at rotation I have a Blend tree animation with two floats ( VelocityX, VelocityZ) that have idle, run , run right, run left , I use a pad to move it at world space When VelocityX is 1 it run left, 1 it run right When VelocityZ is 1 it run back, 1 it run foward It is working fine but the problem comes when I rotate the character in his Y axis, If I rotate the character 90 degrees on the Y axis, This system 'breaks' since blend tree is calculating VelocityX and VelocityZ from world space and not local space, So character is doing 'run foward' animation to go top but hi should do 'run right' animation since from character prespective he is moving to the right How I can implement that local rotation into my blend system? Any help or guide will be apreciated |

0 | Antialiasing shader grid lines I would like to have in game grid lines similar to ones found in Unity editor. There is simple solution(first listing) based on shaders found on unity forums(on right image). However, that solution does not take in account antialiasing and drawn lines looks terrible even few units away from camera. float4 frag(vertexOutput input) COLOR if (frac(input.worldPos.x GridSpacing) lt GridThickness frac(input.worldPos.z GridSpacing) lt GridThickness) return GridColour else return BaseColour In order to address that, I tried using typical fwidth smoothstep combination float4 frag(vertexOutput input) COLOR float distX min(frac(input.worldPos.x GridSpacing), 1.0 frac(input.worldPos.x GridSpacing)) float distZ min(frac(input.worldPos.z GridSpacing), 1.0 frac(input.worldPos.z GridSpacing)) float dist min(distX, distZ) float delta fwidth(dist) float alpha smoothstep( GridThickness delta, GridThickness, dist) return lerp( GridColour, BaseColour, alpha) Even though it has nice fade, the result is not quite near to perfect not only the lines looks thinner(which can be somewhat fixed by increasing width), but also have various artifacts(e.g. in joints) and horizontal lines disappear much sooner than vertical ones. Detail image(anti aliased on left) I am interested in shader solutions, since according to answer to similar question relying textures there in can be no solution with textures. In addition I would like grid lines fade at reasonable distance(when closely inspecting aliased overview image you can see where plane ends) rather than continuing to infinity. Full current version(for testing purposes) with signed distance. |
0 | How to convert world coordinates to grid movement I'm producing a tactical 3D RPG game and I have the following issue I want the NPC to move through the grid. The grid is formed by tiles and each tile has a script attached to it. In this script, there is a variable called TilePosition which is a Vector2Int, that I use it to stores its X and Y values in the grid. The NPC character has a script attached to it called NPCPlayer, where a use a Vectir2Int named NPCGridPosition to stores its position in the grid. Also regarding the NPC, he has a script called NPCMovement. In this script, I've set a raycast that starts from the NPC feet and goes down. I use the raycast to take the TilePosition variable as it is written in the code public void MoveNPC() if (Physics.Raycast(transform.position, Vector3.down MaxDistance, out hitDown)) if(hitDown.transform.tag "Tile") Tile TilesPosition hitDown.transform.gameObject.GetComponent lt Tile gt () NPCPlayer NPCPosition this.GetComponent lt NPCPlayer gt () However, when I try to move the NPC through the grid, 3 rows ahead, he goes away, because he moves according to the world position, rather than moving according to his tile position. I'm using these lines of code to make him move public void MoveNPC() if (Physics.Raycast(transform.position, Vector3.down MaxDistance, out hitDown)) if(hitDown.transform.tag "Tile") Tile TilesPosition hitDown.transform.gameObject.GetComponent lt Tile gt () NPCPlayer NPCPosition this.GetComponent lt NPCPlayer gt () targetPosition.x TilesPosition.TilePosition.x 3 targetPosition.y TilesPosition.TilePosition.y this.transform.position Vector3.MoveTowards(this.transform.position, targetPosition,velocity) How could I make the NPC to move according to its position in the grid?

0 | How to calculate the stopping distance of a wheel collider? I have an 'AI' bus in my game that needs to pull over occasionally at a bus stop. What I want to do is change the acceleration and brake force based on the stopping distance of the bus. I don't want to simply use the distance between the bus stop and the bus because each time the bus pulls over, it could be traveling at a different speed. Right now it uses the distance between the bus stop and the bus. It doesn't really work well though because if a bus is traveling faster, it will take a longer distance to stop and will likely go past the bus stop. Same thing if it were going slower. How do I calculate the stopping distance my bus will take to come to a complete stop? |

0 | Remove delay when changing axis input in the Unity Input Manager I had a problem playing with the Input Manager, where for example When Horizontal ( ) is pressed, it increase its value but, when Horizontal ( ) is pressed, the horizontal value stays positive for a little, but keeps decreasing. This causes the character to continue playing "right" animations and still moving to right for a few seconds, instead of instantly playing 'left" animations and moving to left. The problem also makes the character movie a little after the player releases the key. I have also used Input.GetKey(), but that means the player cannot change the setting from the game launcher, and I don't want to create player setting in game, for now. What I am trying to achieve is when Horizontal ( ) is pressed, then the player presses Horizontal ( ), it should instantly turn left without delay. When the player is not pressing any Horizontal key, it should stop moving horizontally, instantly. This problem also appears along the Vertical axis. How do I make it so input snaps to 1 or 1, with out slowly moving back and forth? |

0 | Getting location bounds of centered text I want to show a dialog box where the user should answer a question. It would look like this The question is aligned horizontally. I don't show the entire question text right away, but it builds up character by character like this To do that, I store the text string in a variable at the script start, then I set the text to "", and in a coroutine I add character after character to the text component. My problem is that (because of the horizontal alignment) Unity wants to build it up starting from the center like this Since this is not what I want, I was thinking that I should perhaps measure the bounds of the entire text while it is horizontally aligned, then I would turn off the horizontal alignment and make it left aligned instead and set its position according to the measure bounds. However, I don't know if I can measure the bounds of the text anyways. Can anybody suggest how to handle this problem? |

0 | Integrating Unity physics with Entitas I've used Entitas a bit and it appeared to me as a great way of creating clean, modular code. I've seen few examples of games created with this framework, and most of them were puzzles, TD's, simple RPG's, etc. Those made me come to think, that ECS like that is not suitable for games making big use of Unity built in physics engine. Rigidbody in this case is part of View layer, but it would affect for example "position" component, so we can't say they are really separated. Unity Physics also works at it's own pace, so there is not really a chance for independent Component System based simulation. Are there any generally accepted solutions, or if I don't wan't to write my own physics engine, I should give up Entitas? |

0 | Goalkeeper Jumping Algorithm? This may be a "best way to" question, so may be susceptible to opinion based answers (which is ok for me). But I would also like if there are any tutorials , research papers , etc. I'm trying to make a 3D free kick game, and I want to decide on the Goalkeeper algorithm. Usually (and in my game) the shot is a function of direction , power and swerve. Maybe wind can be a factor too. So the shots trajectory is pre deterministic, i.e., the point that intersects the goal (or out) plane is determined as soon as the shot fires. So what could be a good approach for the goalkeeper to jump (or walk) ? I have two approaches in mind 1 determine the point, and jump to there. 2 when the ball is closer than a threshold distance, estimate the point by the ball's velocity vector, and jump to there. The problem with the first approach is, goalkeeper will always save the shot, which I want to prevent. So there should be some kind of randomness, or the goalkeeper's ability to jump and walk will be restricted. The problem with the second approach is, when there is a high amount of swerve, the goalkeeper will always fail to save the shot. So how could these approaches be better? Thanks for any help !

0 | Having multiple different friction values on a single piece of track? I am trying to figure out a good performant way to give a piece of track multiple values of dynamic friction. A track piece is 10x10 units in Unity and the idea is to puzzle them together to a big track like the tracks in Trackmania. The game itself features no acceleration, except from gravity. To make things more interesting I want to give each track piece at the start of the scene multiple random friction values within a given range. Currently I achieve this by making each piece of track consisting of 100 little tiles which are 1x1 units and they get a random friction values assigned. This approach works somewhat fine as long as there are less than 30 to 40 track pieces(3000 4000 tiles) but with more than that the fps are dropping really low. As it is a racing type of game I had to set the quot Fixed Timestep quot in the project settings to 0.001 to get accurate time measurments and this is hurting the performance as well. With a lower timestep the collision detection with all the little tiles is really bad too. Is there a more elegant and or performant way to achieve this in within the unity physics system? |
0 | Unity3D RigidBody adding force diagonally (x,y,0) results in two separate movements instead of one diagonal movement? The intentions of this function are to utilize the RigidBody component from a "target" object and clear its force while applying a diagonal force in the direction upwards and away from the side they are facing. I have omitted the portion in which detects the other direction for the sake of simplicity in reading the function as I've been testing this function while the user faces the right hand direction. Variables target refers to the other object currently in the scene targBody refers to the RigidBody component of the target object damage refers to the current damage integer of the object. The damage used in this instance is from the target object facingRight refers to a bool in which is true whenever the current object is facing the right hand direction. public void Damage() targBody.velocity Vector3.zero if(facingRight) Vector3 newVel new Vector3(target.GetComponent().damage 16, target.GetComponent().damage 16, 0) targBody.AddForce(newVel, ForceMode.Impulse) print("Stuff") target.GetComponent().damage 3 For some reason, when I apply the force, the target object doesn't move diagonally. Instead, it moves horizontally before moving vertically however, for some strange reason the horizontal speed is always greater than the vertical speed as it goes so fast that it nearly teleports! I'm not sure if this error happens because of a coding problem on my part that I'm just not recognizing or if it's a problem with RigidBody in which I need to use a workaround for.Anyone have any ideas on what can make this function work the way I want it to? |

0 | Align UI element to gameObject in 2D I have a 2d game where I want to display UI element perfectly aligned to specific gameObjects. I have an ortographic camera and I used to Camera.main.WorldToScreenPoint() function giving it the gameobject position modified, for instance, by 1 on X component to get the UI element on its perfect right. My problem is that the element is not on the gameObject's perfect right, but sensibly above. See this schema Expectation G UI element Reality UI element G I tried also to use the WorldToViewportPoint() but it's not giving the desired result. So, I think this is the right way to go but I can't guess what I'm missing. Any clue? EDIT After a little bit more observations it seemed that the UI element alignment depends somehow on it's distance from the center of the screen (of the camera viewport I guess), so that if the gameObject is below half height the UI element y position won't be on the perfect right but slightly below it and if above half heigth will be slightly above the perfect right. Same for x coordinate. Is there a way I could control this? |

Here's what i have to far. lt summary gt Obscure for type int. lt summary gt public class ObscuredInt public ObscuredInt() this.value 0 public ObscuredInt(int value) this.value value private int a private int b lt summary gt Current obscure value. lt summary gt public int value get return a b set a Random.Range(int.MinValue, int.MaxValue) b value a usage ObscuredInt health new ObscuredInt(5) health.value 10 printInConsle(health.value) This works by simply never storing actual value, but rather a combination of two integers, which sum represents the value. That way the value is actually never cached long time in the memory. So finding it in a primitive way using cheat engine is not possible. My question I've seen other examples of obscuring, which involve conversion to binary or string hashing or other quite heavy operations. This example is of course much more lightweight, how is this example worse than more advanced hashing or conversions. What flaws do you see with this example? What can you suggest? Thank you |

0 | Project transfer, will re importing all my models damage my project at all? Recently I had to transfer my Unity game project to another computer and downloaded the same version of Unity I was using for my 3D project and checked that all the files and folders were in the same place and everything. When I start up the game though my models have vanished and in the hierarchy it just says missing prefab instead of telling me what it was, like it used to if I'd move a model to another folder or something like that. It shows all my files there and I was about to reimport them all but I got a warning that said "Rebuilding assets is only if your project has been corrupted due to an internal Unity bug. It can take several hours to complete, depending on the size of your project. Please submit a bug report detailing the steps leading up to here." I am sure that re importing all my models will fix this but I want to ask if this will have any negative effects on my project or possibly damage anything? This game is extremely important to me and I've been working on it for the past 3 years(being self taught which is why it's taken so long and I'm still learning) Thank you guys in advanced! D |
0 | Why is anti aliasing not being applied to my 2D objects in Unity? I am drawing 2D objects in Unity. Some of these objects are drawn using the standard sprite method that is built into Unity. Others are computed as distance functions in a shader. In both cases I can't get Unity to apply anti aliasing despite the setting being set. Is there an extra step that I am missing that is required to get anti aliasing to work properly? Would it be better to implement my own form of AA in a shader? |

0 | Cave lighting in Unity I have a cave that is inside a mountain (one mesh) that I created in Blender. I would like to make the cave quite dark inside so that either the player can light it up, or it is lit up with things such as crystals. Because I have ambient light through the scene, it's proven to be quite awkward to make it dark, and removing the ambient light kinda destroys the look. I then played around with having a separate material for inside the cave so that I can make it darker, which kinda worked, but then I noticed a big issue with shadows. The following images is from inside the cave far from the entrance. The first image is with the default settings for shadow distance (in this case it was 70 in the quality settings). As you can see in the image, the shadow doesn't fill the cave because of the distance. Second image is with the shadow distance turned up to make sure the cave is in darkness (not pitch black though, due to ambient lighting), this took the setting from 70 to around 500. The problem with setting the distance so high, is that it causes artifacts on geometry outside the cave, which look nasty. What's the best way to make a cave dark (doesn't need to be pitch black) without removing ambient lighting for the whole scene? I was looking at similar art styles to what I am working on, and Grow Home (Unity) is basically where I am heading. They have caves which would be acceptable for what I need, but am not sure how they done it. As far as I know, they have dynamic lighting, as I believe there is a day night cycle, so I don't think anything is baked. |

0 | Shader to see silhouette through alpha blended sprites I want to achieve in Unity a see through effect like the one in these examples In my specific scenario there are a couple of requirements Sprites are using alpha blending, and sprites have transparent areas. There are 2 kind of elements that occlude the character. One should create the silhouette effect, and the other one should behave like normal. For occluding elements that create the silhouette I enable ZWrite, and disable it for elements that doesn't. For the character I tried setting the queue of the shader to transparent 1, and added this pass Pass ZTest Greater Lighting Off Color Color And the effect works partially The silhouette is drawn all over the character, even the parts that are transparent. Transparent parts shouldn't create a silhouette. The silhouette is created when the character is behind a sprite, even if that part of the sprite is transparent. Being behind a transparent part of the sprite shouldn't create the silhouette. The character appears infront the rest of the elements, even if it is behind them. I guess this is because setting the queue to Transparent 1. But if I leave it as Transparent, the character is drawn in the correct order, but the silhouette is never seen. I tried to follow these tips someone gave me, but I'm unable to get it to work 1) Leave the pass that renders the sprites as is. 2) Add a pass that writes to the z buffer, but has a shader that uses clip() to discard pixels based on alpha. You can't use the z buffer to make soft z tests without using MSAA and alpha to coverage. The quality of that won't be great, but it's the best you can do. A faster alternative is a pattern or noise dither, or a good old fashioned threshold if your sprites all have fairly sharp edges. 3) Add third pass to occludable objects that draws the occlusion color using the z test and make sure it's drawn as a final pass. I'm kind of new to shaders, specially in Unity, and I just can't figure out how to make it work properly. |

0 | Help needed, following Unity multiplayer Health Bar tutorial. Only working on Server Host instance of the game was really hoping someone can be good enough to look over my code, I've been trying to fix it for several days. I followed the Unity tutorial which is fairly basic but the bit that confuses me (and potentially where the problem lies) is the if (!server) return part at the top of my TakeDamage() function. The problem im seeing is that once I get to that part of the tutorial, the bullet fired by the Host is registered against the other player and I can see his health has gone down (great so far!) , but when I load the instance in the editor (i did running another standalone on my laptop and connect to internet matchmaking but the same thing occurs) his bullets are not registered (even though my debug log tells me the Ray did hit the player. The tutorial tells me to make it return if not server, it then uses SyncVar and a hook that is supposed to call the method "OnChangeHealth" whenever currentHealth is changed. This DOES NOT appear to be happening, and the TakeDamage code is only happening on the Server Client Host instance. I was trying to adapt the tutorial to my own game, so there are some slight differences in the function and class names, but to me it looks to be exactly the same functionality wise. I will have to just post my full code here as I don't know which part is causing the issue (MANY THANKS FOR READING AND OR HELPING) the Player class public class Player NetworkBehaviour private GameObject startScreen public const int maxHealth 100 SyncVar(hook "OnChangeHealth") public int currentHealth maxHealth private float playerHeight private AudioSource audioSource public AudioClip painBodySound public AudioClip painHeadSound public AudioClip painHeadSound2 public RectTransform healthBar void Start () startScreen GameObject.FindGameObjectWithTag("StartScreen") if (startScreen ! null) startScreen.SetActive(false) playerHeight GetComponent lt Collider gt ().bounds.size.y currentHealth maxHealth audioSource GetComponent lt AudioSource gt () void Update () if (!isLocalPlayer) return if (Input.GetKey(KeyCode.LeftControl)) transform.localScale new Vector3(1, 0.5f, 1) else transform.localScale new Vector3(1, 1f, 1) public void TakeDamage(Vector3 hitPoint, int bulletDamage) check that its Server so that damage only gets applied on the server if (!isServer) return currentHealth bulletDamage audioSource.PlayOneShot(painBodySound) if (currentHealth lt 0) currentHealth 0 Debug.Log("Dead!") private void OnChangeHealth(int health) healthBar.sizeDelta new Vector2(health, healthBar.sizeDelta.y) Inside the bullet class is this function private void CastBulletRay() ray new Ray(bulletSpawnPos, bulletSpawnDirection) if (Physics.Raycast(ray, out hit, bulletRayDistance)) if (hit.collider.tag "Baddie") Debug.Log("ray has hit a baddie") Destroy(gameObject) if (hit.collider.tag "Player") Debug.Log("ray has hit a player") hit.collider.gameObject.GetComponent lt Player gt ().TakeDamage(hit.point, bulletDamage) Destroy(gameObject) and inside The Unity RigidBodyController class I'm using, I added Command void CmdFireBullets() muzzleFlashObject.SetActive(true) audioSource.PlayOneShot(gunFireSound, 0.2f) Create a new bullet GameObject newBullet Instantiate(bulletPrefab, bulletSpawnPoint.transform.position, bulletSpawnPoint.transform.rotation) as GameObject Spawn the bullet on the clients NetworkServer.Spawn(newBullet) |

0 | Unity's Android Notification system works on my Xiaomi, but on a Huawei every notification has an "Unknown" status? When my app starts I check whether there is a notification or not if there isn't I create one via SendNotification(...) if there is, I check their status var status CheckScheduledNotificationStatus(notificationId) On my Xiaomi their status is Scheduled, so I update them SendNotificationWithExplicitID(...) But on a Huwaei it's always Unknown, in that case I create a new SendNotification(...) And replace the old ID in the PlayerPrefs. But on the next startup it's unknown again. Maybe I should use SendNotificationWithExplicitID(...) as well when the status is Unknown so I can keep the ID?

0 | How to slide a non kinematic rigidbody? I'm studying Unity3d, coming from a 2d background, and I'm a bit confused how some things work. I'd like to slide a non kinematic rigidbody, i.e. "just move it forward", like if it was hovering over the terrain. Applying a force makes a ball rotate forward, while I wanted it to slide forward without rotating, also unless that force is huge, a cube just won't move (for the same reason). I understand there are kinematic objects which are "easier" to "just move", but I both think I might really need non kinematic ones, and I think I need to understand them anyway. edit I did try to use some "rotation constraints freeze", but they just prevented the sphere from moving at all. |
0 | Create a stack driven coroutine based state machine for Unity I am working on a game where I am using a coroutine based state machine which is mostly a multi class implementation of this link. I am using it because it allows me to create multi frame sequences. I wanted to know how would I go about making a stack based machine, so that I can overlay game states such as when I want to pause the game to show a menu i can run a pause menu state pausing the running game state, while still allowing the state objects to be rendered in the background Here is the code I am using for a state public abstract class State Inject MonoBehaviour gameObject Inject public EventSystem eventSystem StateMachine parent public State(StateMachine p) parent p public abstract IEnumerator Enter() public abstract IEnumerator Exit() public abstract IEnumerator Update() public IEnumerator Run() yield return gameObject.StartCoroutine(Enter()) while(parent.CurrentState.GetType() GetType()) yield return gameObject.StartCoroutine (Update ()) yield return gameObject.StartCoroutine (Exit()) State machine run function State Current The current state , the one at the top of the stack while(Current! null) yield return Component.StartCoroutine(Current.run()) The problem with this approach is as soon as the state machine's current state changes (That is when i push it down the stack adding a new state on top) , the while loop in the Base state class's run method will end and will call the exit coroutine causing the state to end which is undesirable as according to the stack pattern the state should be paused Moreover as coroutines work in unity, the yield return statement(in the state machine) wont return until the previous started coroutine exits , which is currently as of now responsible for starting the states . My question is how do i alter this code so as to pause the previous state (that will be pushed into the stack) instead of exiting it and starting anew state this implementation works fine if there is to be only a single state in the memory |

0 | Calculating the weight of an object irrespective of the triangle or vertices count in Unity I have a meat piece which I want to weigh. Now there can be anything like fish, cheese, or other items that we can cut and measure. I want the weight to be determined by myself instead of determining from getting the surface of the item as it varies with different tris count. Currently, I am calculating the weight from the following code. public static float CalculateSurfaceArea(Mesh mesh) var triangles mesh.triangles var vertices mesh.vertices double sum 0.0 for (int i 0 i lt triangles.Length i 3) Vector3 corner vertices triangles i Vector3 a vertices triangles i 1 corner Vector3 b vertices triangles i 2 corner sum Vector3.Cross(a, b).magnitude weightMultiplier is a constant value for getting a reasonable weight value. return (float)(sum 2.0) weightMultiplier So if there's a meat piece like bellow and I want it to be a weight of let's say 3kg(6.6lb) then when I cut it into half it should give me values respectively (1.5kg). So I want the weighing factor to be in my control so that if in the future we have really detailed high poly items the weight shouldn't get affected by that. |
