0 | Smooth rotation Unity3d I have an animation and I modified some rotations of some bones in the animation at a certain frame. What I want to do is how to make the animation in the next couple of frames interpolate smoothly so that the changes I made looks smooth? Like for example, if I have an animation of a game object, and in frame number 100 it rotated 90 degree in the x direction. So now frame 100 has a modified rotation angle of the object, but frame 101 has the original animation. I want to smooth the rotation so that the transition of the obect from the modified frame back to the original animation looks smooth. |
0 | Unity Running code on the "Create Other" menu? Right now I am trying to create a TextMesh GameObject from code. The graphics primitives are accessible through PrimitiveTypes, I'm thinking there must be something similar, and if not, I could at least run whatever static function is bound to the menu if only I knew the name. The more general question is "how one get at all the other items on the "Create Other" without using the menu itself?" |
0 | Should I calculate in meters or pixels In my car sim I am doing my calculations in Standard Units, except for the distance which is in pixels. Is this still correct (my guess is no) or should I use Meters ? If I should use meters what is the best way to go about it? should I just pick a scale 10px 1m or is there a better way to do this ? thanks in advance. Some additional info I'm using Unity3D and using its physics engine. |
0 | Combat System Class Objects as Package and Listener So I've been trying to map out a combat system and I have an idea I'm laying out that I'm looking for a sanity check on, as well as suggestions. The idea is that all things that can do damage (weapons, spells, environmental traps, monsters that deal damage sans weapon) will have a CombatTalker() object attached that will contain information about the amount of damage and damage types (fire, frost, physical, magical, etc.), modifiers that it might have, and any special effects (apply DoT, blind, slow, etc.). Everything that can take damage will have a CombatListener() object that takes that information and transmogrifies it with the receivers resistances and any special properties it may have. The CombatTalker() will create a CombatPackage() from a collection class any time there is a collision, and send it to the CombatListener() on the collided objects, supposing it has one. The CombatPackage() is basically the raw data about the damage and effects. The CombatTalker() is a wrapper of sorts that generates the CombatPackage() based on the weapon (or whatever) base damage, then the specific details of that individual weapon, and sends it (like a network packet) to the CombatListener(). The CombatListener() unwraps the package, and in reverse applies the resistances then applies any relevant damage and effects. I know some of that was slightly repetitive, but I was trying to outline the idea completely, which apparently took two paragraphs. I know this might be slightly complex, but the creatures and players and weapons and spells can change over time, so there isn't just a pool of static data that can be attached to the item. It needs to be able to read stats from JSON, apply specific information about the damage and send it. The same goes on the other side in reverse. Is there a reason that this is "too complex"? Am I considerably overthinking it, or is this a reasonable method for a combat system? Thanks! |
0 | Loop in coroutine stops after going halfway I have a very weird problem with a particular loop in a coroutine public IEnumerator DestroyCubesGameOver() var startingCubeHolder GameObject.FindWithTag("StartingCubeHolder") DestroyOutOfCameraCubes() Debug.Log(cubeGroup.transform.childCount) for (int i 0 i lt cubeGroup.transform.childCount i ) Debug.Log(i) Destroy(cubeGroup.transform.GetChild(i).gameObject) yield return new WaitForSeconds(0.001f) Destroy(startingCubeHolder) The loop starts doing its thing and it needs to do it 100 times for example. However it stops after going about halfway and after destroying about half of the objects. Even if I increase the delay for each repeat it still does the same exact thing needs to repeat itself and destroy 100 objects, ends after destroying just 50. What is causing this? Edit If I make it just a void method it destroys all of the objects. Edit 2 This loop was initially a foreach but I rewrote it to try the other way same thing. |
0 | Why can't I expose a Plane variable in my unity script? I've got a script which creates raycasts. I wanted to use the (presumably less expensive) Plane.Raycast rather than the GameObject.Collider.Raycast (because the gameobject one has a distance parameter so that's one more check) I can expose the plane gameobject in my scene easily by simply making a public gameobject variable like this public GameObject floor however when I turn it into this public Plane floor It doesn't expose in the scene. Why is this? |
0 | Unity Problems with scene object orientation and rotation after updating my project from 5.0.0 to 5.2.2 Last year I made a large project on Unity 5.0.0, today I re opened it on 5.2.2 to do some work on it. I was given the message that the project needed to be updated, I allowed it to do the update. Now when I open up my scenes, many of my scene objects are misplaced, the rotation is completely wrong and positioned in the wrong place. My scenes are of a refinery and the most commonly broken object is the pipework, something that would take hours to correct manually. My pipework is created this way... All pipes are made in blender and each scene's pipes are saved as a single blender model (with each pipe make from a bezier curve and left as a separate object). Once imported into Unity (as a single .blend file), I've then dragged and dropped coloured materials onto all the individual pipes, so they are all coloured correctly. This has all been fine until updating the project to 5.2.2 now some of the pipes are in the right place, but many are rotated in completely the wrong direction, leaving it looking a mess. If I delete the pipes from Unity and reimport the pipe model back in, this would solve the problem, but then all the materials colours will be gone. Due to the sheer amount of pipes throughout the whole project, to re colour them all again would be an extremely problematic task, especially as it's critical that the pipes are the right colour. I am confused how some of the pipes within the same pipe model are fine and the others are wrong, it would be so much easier to sort if they had all changed rotation together, then I could just switch them all back in 1 go. I have a total of 13 scenes and so far all of them have suffered the same problem. Nothing whatsoever has been changed on any of the scenes, assets or indeed anything in the project folder. In fact I haven't touched a single file within the project since October last year, so it is certainly to do with updating to 5.2.2. Is there anything I can do to fix the problem without having to re import the models back in or manually rotate everything back? I have attached some screenshots to show the issue See how in the blender image, all the pipework is placed correctly and then in the Unity image, half the pipes have flipped and are facing the wrong way. I have removed the ground so this can be seen clearer. Any help would be much appreciated. Many thanks |
0 | How can I make the camera to rotate from side side but in static movement range? I mean for some reason now the camera is rotating to the left and to the right but sometimes it's rotating to one of the sides a lot I mean a very sharp angle and sometimes less rotation. How can I control how much rotation will be from side to side by degrees ? using UnityEngine using System.Collections public class scr camera MonoBehaviour public float rotate amount Use this for initialization void Start () Update is called once per frame void Update () transform.rotation Quaternion.Euler(transform.eulerAngles.x, (Mathf.Sin(Time.realtimeSinceStartup) rotate amount) transform.eulerAngles.y, transform.eulerAngles.z) Sometimes cam14 make almost 240 even close to 300 degrees rotation to one of the sides sometimes less. The rotation is not equal to both sides. I want simple rotation to both side just to see the room and not the walls behind the camera. In this case I set the rotate amount to 7 so it will rotate faster. |
0 | Unity Blend tree weird transition I have duplicated the blend tree from the ThirdPersonCharacter (Ethan) which comes with the Standard Assets package. In the duplicate I went into the blend tree and swapped out the walk animation "HumanoidWalk" with my own animation named "walk", but now I get a weird transition from the animation "walk" to "HumanoidRun". Both animations, my walk animation and the original "HumanoidWalk" are root animated and look similar they have around 1.5 velocity both and same frame length. Animation Settings I created the animation in blender, you will see in my video below that the animation itself runs smooth and as it should, but the transition to HumanoidRun is very weird for unknown reasons. I am using a custom metarig armature which comes with the blender add on "rigify", I deleted some bones on the finger, but the avatar has a check and is ok (no warnings either). Rig Settings Player settings I basically "copied" all the components from Ethan (ThirdPersonController) and only changed the Animator Controller and the Capsule Collider settings to match the model. I made some short videos where you clearly see the problem, it happens if the parameter Forward is at about 0.6 0.8. https youtu.be Q T7FplDxLE https youtu.be nrJNeo1ltsg NOTE First I am demonstrating how it looks with the normal animations, then I add my own. What am I doing wrong? More Infos I just baked the walk animation in blender and exported it to unity again, but this made no difference. I tried to export it from blender as FBX, it made no difference. However, I noticed that the import is happening much faster and applying in unity importer is very fast now. |
0 | How to make player stay on a moving object I've made an obstacle course with various moving parts to test out movement of a player. In the obstacle course there is a section where there are multiple cubes moves from side to side, and you have to jump from one to the other. But regardless of their speed, I can't seem to get the player to stay on top of any of the moving cubes. I have no clue how to fix this my only guess would be to use materials, but I can't apply any to the character controller. I appreciate any suggestion that you can give. Also the movement is done as an animation that I created in unity in the animation window. Thanks, Nova |

0 | How can I use Body tracking in Android using ARCore or some other libraries? I know that ARCore on Android doesn't support Body Tracking like ARKit does. But is there some alternative or workaround to achieve it? Some other SDKs or Libraries or maybe even if there is some way to do it through ARCore itself? To make it clearer I plan to use something like this in an AR game for Android. I plan to develop it in Unity 2019.4.x. My search result in Google didn't yield a useful result as it gets mixed with ARCore Motion Tracking (which isn't what I am talking about here) or implementation with ARKit. But I got a little hope that there might be some way out after reading this post on Unity Forums. |

0 | How to start in animating my model? I got a model from TurboSquid. Which is an archer and when i imported the model I got all the textures to be put on properly. The thing is the actual character has no children nodes, is it possible to still animate this model. I have looked throughout the files and there are a bunch of textures, but I don't happen to see any animations. Along side that the asset comes with an Avatar, I looked on the docs and still a little confused as to what that is about. If I cannot animate this model how could I force it to animate somehow or how could I make my own model. I am not a artist at all and just focus on the gaming logic and and programming, and I am working solo. Just wondering what are some options to get a game up and running with some decent graphics. So, far I use the model to get the game play down, but now I want to make it visually appealing. |

0 | Season system Implementation system in unity So I am planning on implementing a seasons system for a 2D top down game. Each season will have a characteristic terrain feature e.g. summers will have patches of grass spread out .. which I wanna reproduce by green bloat spread around on a 2D plane or quad... These features will need to generate dynamically for every season. The implementation will be simplistic nonetheless... using green bloats for grass patches, blue bloats for waterholes.. Can you guys give me like pointers to solve this problem?

0 | Unity change sprites to something that uses less memory I have a game that uses only silhuette textures, but they take up waay too much memory (360 MB overall and this is a mobile game) so I plan to avoid using sprites with alpha punchouts (1 bit alphas). From what I gathered, I could use an asset from Unity store like SVG importer, but I have no financial means to do so. So I plan to make low poly 3D (in fact 2D) planes that somewhat cover my textures. Now, I have a lot of sprites already. I saw that Unity can create a 2D mesh collider around my sprites. Can I use that to create my meshes and then apply a single colour unlit material to them? How would it roughly effect memory usage as opposed to my generally 500x600 sprites? If I'm going in the wrong direction, is there a way to create Shapes, just like in Photoshop or GIMP? |
0 | Unity Shader blending colors and color values above 1 I have source images where each pixel is one of exactly 4 colors red (1,0,0) green (0,1,0) blue (0,0,1) black (0,0,0) I'm trying to modify Unity's default sprite shader to use those colors (besides black) as a key to change to other colors. For example, any pixel that's red should become RedColor. My first attempt was fixed4 RedColor fixed4 BlueColor fixed4 GreenColor fixed4 frag(v2f IN) SV Target fixed4 c SampleSpriteTexture (IN.texcoord) IN.color fixed4 modColor modColor.rgb RedColor.rgb step(1, c.r) modColor.rgb BlueColor.rgb step(1, c.b) modColor.rgb GreenColor.rgb step(1, c.g) modColor.rgb c.a return modColor This worked. The problem was it was very jagged. In exporting the image and being compressed in Unity I think some pixels had multiple colors but the shader simply would set the color to the last matching color. So I tried to modify it to not reset the color if the next color matches, but instead blend between any colors present in the pixel weighted by their contribution. Here was my second attempt fixed4 frag(v2f IN) SV Target fixed4 c SampleSpriteTexture (IN.texcoord) IN.color float total c.r c.b c.g we set the total to 1 if it's 0 so that we don't divide by zero when the color is black total step(total, 0) c.rgb RedColor.rgb c.r BlueColor.rgb c.b GreenColor.rgb c.g c.rgb total c.rgb a return c This also worked and the jaggedness went away everywhere except the border of black and nonblack colors. So then I tried getting rid of the total and it was perfect fixed4 frag(v2f IN) SV Target fixed4 c SampleSpriteTexture (IN.texcoord) IN.color c.rgb RedColor.rgb c.r BlueColor.rgb c.b GreenColor.rgb c.g c.rgb c.a return c It's perfectly blended between any of the pixels. But I don't get why. I was dividing by the total so that the color values wouldn't go above 1 and it would blend between them. For example if a pixel had both red and blue present it would be adding the 50 of RedColor's rgb value and 50 of the BlueColor's rgb value. So when I didn't divide by the total it appears nothing changed besides blending between black and other colors. This implies to me that I never had any pixels that actually had more than one nonzero color component to them (or else I could would be getting white colors at those pixels). But if that's the case, why did switching from the first step function approach to a blend approach even do anything? This is my first foray into shaders so it's entirely possible I'm doing something terribly, but I just want to wrap my head around what's going on and why. So I definitely appreciate any help ideas. |
0 | Do I need a server if I only want to upload data to a DB? I'm currently creating a game where people get some kind of reports for their game performance on a website. Let's say, you log in, play the game, the system gathers your performance data and this is being sent to a database so that it can be read and interpreted by an external website later. For this, I'm using a firebase real time database and it's working fine by now. I'm pretty noob with unity and I have read and watch tutorials on the internet where people actually create a server to achieve this but do I really need a server when the only thing I need to do is to post data to a database based on users? This isn't really a multiplayer game, but there is some kind of information which is shared for example sometimes I need to get those data in order to get high scores and that kind of small information, but that's it. I'm using unity webgl and firebase for the moment, and everything is working fine, but then why people always create a server for this? PS sorry for my bad english |

0 | Bullet physics C script Is imparting force on rigidbody objects I have recently made the simplest gun and bullet script that I could and it works amazingly, except for one problem that I've found. When I attach it to a game object with a rigid body the force of the bullets move the object back with quit a bit of force. But what I can't seem to figure out is why the bullets are imparting force on the object at all. The bullets do not have a rigid body component. The way my guns work is with two scripts, one which acts as a simple spawning point when a key down event is given and what ever object you give it to spawn. The second script is applied to the bullet itself which causes the bullet to have motion through transform.Translate with a speed variable. The best example I can give of this is when I attached two guns to the default unity jet and when I fired, it had enough force to move the jet back against its thrust speed. I really would appreciate any help with this so I can move on with my project. I will provide the code bellow for the two scripts.

0 | Unity How to manage a large amount of prefab variations? The project that I'm working on demands the ability for game designers to be very flexible when balancing, customizing items, etc. The most difficult requirement to meet at the moment is that they want to drag drop, say, a weapon prefab onto a weapon field in some game entity component and from there be able to tweak the prefab's parameters. If I provide some tools that create derived prefabs at such moments, then we'll end up with possibly hundreds of pretty much same prefab variations and also loose the ability to edit the initial prefab and transfer the changes to derivatives. What I'm starting to consider is introducing a "Data Map" structure in every entity that requires high level of parameter customization. Every parameter would be set through methods like Set GetFloat("key", "value"), Set GetFloatArray, Set GetInt, etc. So basically a dictionary that maps a string to a predefined set of data types. When a prefab of such entity would be drag dropped into a field of another component, an editor tool would separate the "Data Map" from the prefab, allow the game designer to tweak the values of the keys and eventually serialize it to json. During runtime uppon instantiation of a prefab with a "Data Map" a manager would check the deserialized overrides and override the "Data Map" with the tweaked values if needed. Though to me this sounds overly complicated and maybe some of you had a similar situation and came up with a simple solution? Maybe it's worth trying the ECS approach? Thanks. An example Let's say there are prefabs Axe, Sword, Bow with a bunch of parameters configured, say Damage, Durability, etc. There are many other components that can accept a weapon prefab and once it's dropped, the designers want to have "on the spot editing" say, okay, for this situation here the Axe prefab needs to be a little different and have Damage 3. Creating a new prefab means that the link to the initial Axe prefab is lost and there are now two Axe prefabs that need to be managed this is the problem we're trying to address. |
0 | How to avoid overwriting a value in Unity? I'm working on a Tower Defence style game, and wondering how best to handle the quot resources quot part. I have multiple enemies on screen at a time, and when an enemy dies, it updates a resource that allows the player to build more towers var tower Instantiate(buildables 0 , center, Quaternion.identity) var controller tower.GetComponent lt TowerController gt () controller.OnKilledEnemy (sender, args) gt int.TryParse(goldAmount.text.Replace( quot , quot , quot quot ), out var curr) curr args.gold goldAmount.text quot curr n0 quot But if 2 enemies die in the same frame, wouldn't the value there miss an update?

0 | Stop player following cameras cameras direction Okay I'm not going to go to much into it but this is what I need my script to do. The way I have my controller set up is that the camera looks to the side of the player a little bit. I use this for aiming attacks, bullets and what not. The problem is that it follow the camera when it looks up causing my character to slightly jump ever time I aim and look up. So i want the player to move with the camera while ignoring its y axis. and i need my character to jump so i cant just make the players y movement 0.

0 | How do you exactly implement a Semi Implicit Euler type of movement in a 2D platformer? So I've been following along Sebastian Lague's 2D platformer tutorial, and to understand exactly how the physics of how a jump is done, I dug into the subject and noticed a lot of people, from GafferonGames and Kyle Pittman, all mention using Semi Implicit Euler in making an accurate jump. Now my problem is How do you exactly implement this type of integration scheme in a game? Specifically a platformer. A comment on the tutorial I was following said that the code below uses the Explicit Euler type of integration. Though I'm not exactly sure myself on whether or not this is true another tutorial I found on the topic, specifically Jorge Rodriguez's Math for Game Developers uses the Semi Implicit Euler integration to make a spaceship simulator, but the code used was C and I only have some limited C and I was not able to fully understand parts of the code that went into implementing the integration. Specifically auto v vn, gravity (Vector x, float h) gt Vector return vn gravity(x) h auto a xn, gravity (Vector v, float h) gt Vector return gravity(xn) gravity(xn v h) h from what I understand, this function returns a Vector2, but I don't know if the auto a xn, gravity is supposed to be about declaring a variable or what, or how the vector bit fits in the whole code. All in all, I need help, I'm still pretty new to programming and general and these small nuances confuse me. Any help is greatly appreciated, Thank you.

0 | Objects rendering only on editor, but not on build (they get invisible) Everything works fine in the editor, but when I build the game, none of the objects in the scene are rendered, and only the skybox and UI text is visible. But although they aren't appearing, they are working as normally (i.e. these objects' triggers work normally when the determined event occurs, like for example, colliding to a specified object, or in other words, they are invisible). I searched for this issue but didn't found any answer. Could it be my cheap computer's fault (Intel Celeron without an external graphics card)? In editor game mode In buit game I ran both the editor and the built game in the same quality, and also tried to run it in Fastest quality, but no, it made no difference in the built game. Also, there is no object tagged with "Editor only", only one have a custom tag and all the others are "Untagged". And the camera's culling mask is set to "Everything". The result is the same either for web or Windows. Edit OK, I built for Android and the objects render normally. So, I'm not completely sure, but probably it's my PC that can't render the objects, because both building for web plugin and desktop have this disappointing result, but for Android it works perfectly (even the shadows, which wasn't being cast in the editor), so... |
0 | Unity 2D Input.gyro eulerAngles X value strange behaviour I am working on a project where I want to create an 'scrolling' effect using gyroscope on mobile devices. The basic idea is that I have an Image object in my Scene and I want to be able to show different part of it using gyroscope like for example you see the wall of a room and rotation your phone you see different parts of the room, but in 2D. For now I managed to move my Image using Input.gyro.attitude.eulerAngles.x from gyroscope like this protected void Update() var x transform.localPosition.x var gyroX Input.gyro.attitude.eulerAngles.x x gyroX Speed BackgroundImage.transform.localPosition new Vector3(x, transform.localPosition.y, transform.localPosition.z) The problem which I am seeing is that when Input.gyro.attitude.eulerAngles.x reaches 86.0 it starts decreasing and even if you are rotating your phone to right it changes it's direction. Checked the documentation, examples over internet, but didn't find anything about that. If you have any idea what can cause that issue and how can I fix it, or any other suggestions how can I achieve the thing which I want to create, pleae share your knowledge. Thanks in advance! Edit The only rotation axis which I am interested in is X, because the app will be in portrait mode and I want to be able to move the image only horizontal (by X). So the phone's rotation has to be similar to while taking an panoramic photo on your mobile as shown on the first picture |

0 | How to rotate a local position offset based on a direction vector? I'm trying to fire three raycasts in the direction of movement, from offset starting points. I'm having trouble calculating the start positions of the rays based on the direction. As you can see in the animation, the three parallel lines in the middle overlap when moving upwards using the code below, but I want them to remain evenly spaced. I cannot use transform.right (up etc) etc because the transform is always facing the same direction by design. Instead I am using the currentDirection which is the normalized last movement velocity. I want the lines to always be evenly spaced based on the direction the object is moving without rotating the actual transform the problem is I don't know the math behind it and have spent last several hours trying to figure it out.

I am trying to figure out if I can afford to put this feature in my game I would like to have the enemies killed to pile up in a sort of heap, so I was thinking about not using the same old destroying routine after they die. The game itself is really simple, it's 2D and for mobile. It has a fixed background and there's not much moving around aside from the player, the enemies and few npcs (which would get destroyed when offscreen), we're talking around ten 32X32 sprites onscreen at a time. Once dead the enemies would not be removed but they wouldn't need to be raycasting, colliding, ecc.. Just only be there for visual sake. So the question is would a mobile device easily handle not removed enemies in the order of a hundred or so (I could destroy those at the bottom of the heap) and not slow down or crash the game? Are there some example of this kind of feature (other games that don't destroy dead enemies)? Or is there a good practice too keep enemies in game without impacting memory resources? Thanks for the attention. |

0 | Visually updating the position of a game object controlled by an animator controller I have a game object that is controlled by an animator controller. In order to activate the next animator state, the user is supposed to grab this game object, and then move it from Point A to Point B. As a test, in said game object's Update() method, I added the following line this.transform.localPosition Vector3.up When running the game, I can see that the y coordinate of the game object's position increases every single frame, just as intended. However, visually, the game object's position is not changing at all it remains in the same place all the time. What should I do to ensure that game object's position is also visually updated?

0 | Setting up a low res viewport to stretch in Unity I am working on porting a low res game over to Unity. In my previous engine, I had the option to set a native resolution (say, 160 x 144), and it would automatically stretch when the player entered fullscreen (with options for whether you wanted to keep the same aspect ratio, or stretch). I am having trouble figuring out how to set up something similar in Unity. I see that you can play around with resolution settings from Edit Project Settings Player. I tried various combinations of Default Is Fullscreen, Default Is Native Resolution, and Default Screen Width and Default Screen Height, but I haven't been able to get it to work. When I play the scene in the editor, the viewport is still much larger than my desired resolution. And when I Maximize On Play, the FOV is even larger. I Googled around, but couldn't find an answer that helped. Any advice? |
0 | How do you have rigged clothing animate with a base model? How do you have rigged clothing animate with a base model?

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

0 | Unity how do I edit a second scene when my objects are still in the first? I have my game set up so that objects like the Canvas and the main character are set to DontDestroyOnLoad they're only initiated in the first scene. However, this means that when I load my second scene in the editor, those objects aren't there yet. I could copy and paste them over, but then the objects in the second scene will be duplicates of the ones in the first.

0 | Building an Octree for terrain generation I've previously implemented marching cubes tetrahedra to render an IsoSurface. It worked (YouTube), but the performance was dire as I never got around to implementing variable Level of Detail based on view distance (or even removing old, distant chunks). I decided to have another go and do it properly this time. I've started by creating an OctreeNode that works as follows when Build() is called. If the chunk is too small to build, return immediately. Work out if the surface passes through this chunk's volume. If so, then decide if we want to raise the LOD (because the camera is close) If so, then spawn 8 children and call the same process on them If not, build the mesh using the current node's dimensions Some PseudoCode OctNode Build() if(this.ChunkSize lt minChunkSize) return null densityRange densitySource .GetDensityRange(this.bounds) if(densityRange.min lt surface lt densityRange.max) if(loDProvider.DesiredLod(bounds) gt currentLoD) for(i 1 to 8) if(children i null) children i new OctNode(...) children i children i .Build() else BuildMesh() return this As well as returning density at a point, the density source can determine the possible density range for a given volume. The LoD provider takes a bounding box and returns the max desired LoD based on camera position frustum, user settings, etc... So... This all works fairly well. Using a simple sphere as the Density source, and showing all nodes And just the leaves However, there are a couple of issues I have to define the initial bounding volume (and the larger it is, the more processing I need to do) At the root of the tree, I have no idea how deep the leaves will be, so my LoD numbering starts at lowest quality (root) and increases as chunks get smaller. Because LoD is now relative to initial volume, it's not much use when I want to do things at specific sizes qualities. I've thought of a couple of options but both seem flawed Maintain a collection of Octrees and add remove depending on distance. Can't see how I'd mesh across nicely , plus I'd need a list of known empty nodes, especially if I want arbitrary 3D surfaces (to avoid re calculating empty volumes repeatedly) Add a parent Node to the current root, then add seven siblings for the original node. This would work and be on demand but it seems complex to shrink back down sensibly as the player moves through the landscape. It would also make LoD numbers even less meaningful. In clarification to Q below At present, if 2 physically adjacent nodes in the tree are at different LODs, I have some code to coerce the verts such that there's no seam when the meshes are generated. I'm able to do this by knowing the the density for multiple of surrounding nodes. In a scenario where I have 2 independent octrees side by side, I'd have no easy way to retrieve this information, resulting in seams. What's an optimal way to approach this? |
0 | How to use a .cube LUT file with Color Lookup? I have used quot Image 2 LUT quot to create a LUT for Unity from a certain movie. However, currently quot Image 2 LUT quot only outputs quot .cube quot files. For HDRP, this is great, but for some reason, URP doesn't accept .cube file. URP expects specially laid out .png LUT file. Is there any way to convert a .cube LUT file to a PNG that I can put into the slot of Color Lookup gt Lookup Texture with URP? Unity expect this format The tutorial that Google finds and recommends is this. However, I don't have Photoshop. Also, the tutorial deals with a square LUT that looks like this So even if I had Photoshop and I would follow the tutorial, I would still have a square LUT which is not laid out as Unity would expect it, so I did not use that tutorial. How do I create a LUT png from a .cube file that I can use with URP? Thank you. |
0 | 2 D character not falling to the ground I am very new to Game Development and I am making a game with a simple Ragdoll which has a body, a head, and 2 limbs(hands). The head and the limbs are hinged to the body and I have kept the Ragdoll above a cube to be used as the ground on which the Ragdoll falls. Till now, I haven't added any scripts for movement or anything, I just want my Ragdoll to fall on the cube below it properly. But when I click play, the Ragdoll just starts to float above its original position. When I move it through the editor away from the cube(ground), it does fall down. It's like the cube is opposing the downward acceleration of the Ragdoll. The Ragdoll won't land on the cube. All the bodies have Rigid body and collider scripts. The Ragdoll also doesn't disassemble, it manages to keep itself together. Can someone please tell me what I am doing wrong. I researched about this but I have found no solution. I am using the free version of Unity. |
0 | How can I create an extending chain like the hookshot in Zelda in Unity? In the Zelda games, there is an item called the hookshot. It is a small mechanical apparatus held in one hand that acts similar to, but not the same as the gun. When it is triggered, the hook at the tip of the item springs forward and an extending chain follows behind it. This chain is spawned when the hookshot is triggered and disappears when the hook is retracted. The chain is not visible beforehand, i.e, it is not spooled around any kind of cylinder and unspooled when shot.There are also other games where characters use grappling apparatus that can be made shorter or longer when a character is hanging from a specific point or pivot. Similarly, this grappling tether is created or hidden as needed to support whether the player wants to shorten or lengthen it. My question is, how could one create an extending chain whose links are only visible when triggered and when retracted disappear from view? This chain does not need to necessarily interact with physics. I've thought of a couple of ways someone could create an effect like this, but I would rather see if there is a better known solution or implementation of this or a similiar effect before I dive in. Potential solutions could include A particle effect between the base of the hook and the tip of the gun. This might be far better suited for displaying a non physical, energy tether, but I am not as familiar with the particle system in Unity and I am curious to see if a chain link could be faked with a particle. Creating a chain link by link or section by section procedurally based upon the direction the hook was firing in and the distance between the positions of the gun tip and hook base. This seems like a more direct solution, but could have higher processing cost as the links are created on the fly and in rapid succession. Creating a chain that is hidden when not fired and is made to slowly appear when fired as the hook leaves the hookshot apparatus. This seems like the most likely solution, but I have little to no idea as to how it could be implemented. I would not be surprised at all if there is a better solution that I didn't mention. I look forward to seeing what people suggest. Thank you. |
0 | Unity sprites and layouts I am trying to learn Unity for a simple board game. The question is, is it possible to use grid layout group (or any layout component) with sprites? The goal is to fit a board into my view regardless of the aspect ratio of the device. The following grid should contain 7 by 7 sprites and it should scale up and down (no more then lets say 100 px) and have an aspect ratio of 1. I've tried adding a canvas and a panel that has a grid layout group component but it seems like sprites are not affected when added to the panel. Also it seems like when I try to work with a panel or a canvas they have a fixed sizes in units. Having fix sizes feels a little bit off. Is there a way to use layout components so sprites can have relative distances between them. So far I am stuck and lost in tutorials and feeling like the answer should not be this complicated. Any push to the right direction is welcome. |

0 | Per component Shader Blend in Unity Context I'm writing a 2D mobile game in Unity where the graphics are essentially black lines drawn on a background image plus some lighting. Running full RGB calculations for every step seems like a waste of processing power. What I'd like to do is render everything in grey, alpha and then multiply by the sRGB background image in a separate shader at the end. Actually, ideally, I'd like basically to specify custom components like grey, highlight, additive, alpha , each of which can be ignored in a given pass, and then do a custom operation with those when I apply the background image, like ceil(src (dst.r dst.g)) half4(dst.b). I can figure out how to do that between 2 textures within a shader, but not between texture and screen (a.k.a. src amp dst). Question Basically, is there a way of writing a per component replacement of the built in Blend functions? Because something like Blend SrcAlpha OneMinusSrcAlpha only works with the full float4 or half4 vectors. Or do I need to grab the screen like a texture and handle it within a pass block, and then do Blend Off or Blend One Zero? Or do something with RenderTextures perhaps? My intuition suggests that that would undo some of the efficiency I'd gained in previous steps, though...? |
