I found RenamedFrom, but can't get it to work

regal lava
#

oh, yeah I think I remember seeing something like that

austere jewel
#

It works on fields. Renaming classes just works, because the meta file hasn't changed.
If you're using SerializeReference then there's some stuff if you moved namespaces/assemblies.

light falcon
#

sometimes if I rename a class and a file's name from inside visual studio, all gameobjects that had the file attached give a missing reference warning

austere jewel
#

Sounds like an issue with VS then

#

A functioning IDE should know you're working in Unity, and when you refactor a file or class name it should rename the associated meta file to match

light falcon
#

i think vs deletes/recreates the file

#

sometimes it works fine, sometimes it doesn't

#

it's 50/50

#

guess I'll manually fix it

#

is there a way to find all missing references in a project?

  1. this is not advanced. this is #💻┃code-beginner level at best
  2. see how to correctly share !code below
  3. and finally, where do you call start? because that isn't the same as Start which is what Unity will call automatically

Silly question. I have a private attribute of type Queue<T> named myparam in class A that I want to get updated by a public method member of class A when it is called by another class like Class B. When I pass the Queue<T> as an parameter from class B to the public method in class A that will then update the class A Queue<T> attribute, I found that I have to use Enqueue with a loop on the queue to properly pass the Queue values so they stay in memory. Otherwise just assigning the value such as this.myparam = param doesn't update the class A private attribute myparam when I check the queue with myparam.Count in the Update method of class A and myparam.Count returns 0. Is this expected with Queue<T> types and Enqueue is the only way to deal with this?

# tough summit Silly question. I have a private attribute of type Queue<T> named myparam in cla...

Your issue is not singular to Queue. It will happens with any type. Whenever you assign something for reference type variable, it changes what it points. All other reference to the same object will still points to the old object.

To solve the issue, you can wrap it in a container such as:

public class MyWrapper<T> 
{
  public Queue<T> MyQueue { get;set; }
}

However, ideally, you never want to pass Queue from a class to an other class. This is bad practice. You should encapsulate the Queue completly in the class and use the class. By example, adding function such as Clear or Reset. I suggest you read on encapsulation. https://www.sumologic.com/glossary/encapsulation/

This is a very specific question, and I'm not sure if this is the right place to ask it, but I have a problem with my game. I have designed a way to turn pixels into game objects so I can just create pixel art and turn it into a level, but the problem with this is that I can have thousands of game objects in one level, which makes the game run very slow. I spent the last couple of days learning how to use meshes, and I thought that I would be able to combine all of them together, but I got an error when I tried to run the coding stating: "ArgumentException: The number of vertices in the combined mesh (92424) exceeds the maximum supported vertex count (65535) of the UInt16 index format. Consider using the UInt32 IndexFormat for the combined mesh to increase the max vertex count." I am sure I could figure out how to use UInt32 like the error reccomends, but this made me realize that the mesh isn't just an outline of my level, it also has hundreds of lines between the blocks where the player could never reach. I am wondering if there is a way to to combine all these game objects into one, combine any that are directly touching, or even just combine any large squares into one game object. I am okay with using external tools, like Blender, provided I am able to do everything on runtime. If I need to write logic to procedurally check for objects that could be turned in to larger game objects, that's fine as well. I am relatively new to Unity, but I am willing to invest as much time and effort into this project as is needed. Any solutions, or even other avenues I could explore, would be incredible helpful.

What do you mean by:

I have designed a way to turn pixels into game objects so I can just create pixel art and turn it into a level

Also, what you seem to describe is static bashing. Usually, using 65535 vertices is more than enough because you would cull part of it anyway. However, if you want more you can simply increase the size of the index buffer. https://docs.unity3d.com/ScriptReference/Mesh-indexFormat.html

Static batching seems to be exactly what I'm looking for. My script takes a specified png file and scans the image pixel-by-pixel, using the RGB value of the pixel to add a game object in that position. Here is the level I used that gave me this error, where black is the ground (each pixel is a game object) and green is where the player spawns (the resolution is low because its only 128 x 72 pixels):

# dusty wigeon I am going to ask if it is really necessary to have to make your level from a PN...

I feel like it's the most practical solution, but correct me if I'm wrong. I want to be able to make at least 100 levels, looking something like what I've drawn above. That picture took me 5 minutes to make and allowed me to play it instantly. Instead, if I had made the level in the unity editor, that level may have taken me at lest 20 minutes to make. In addition, the game objects would likely take up more space than a small png file, and the png allows me to easily change things like the size of the tiles and the player's starting location. Also, any details such as that stalactite would be very tedious to make using game objects, and I am planning on drawing over the level anyways, this map is only needed for collision. My game is a platformer with a pixelated feel, and I feel like this is the best way to be able to effeciently make new levels. Aside from the time and effort required to write the function to take the image and convert it to a level, this feel like the objectively better solution. If you disagree, could you let me know why? This is based off my opinion as a gamer and coding with little experience in Unity, so I'd love to know if there is a better way.

#

Also, thanks for letting me know about static batching. I just got it to work with my game, and my stress test that would have been almost 40,000 game objects before is now running with 2 batches and >150fps. (Edit: actually I zoomed the camera out and it dropped to 20fps, but compared to crashing unity before it's still an improvement.)
I also forgot to mention, I gave my computer to my friends who want to help me with development and they were able to make and play their own levels in under 20 minutes. Neither of them have any gaming, coding, or game development experience, but now they can just send me an image and play their level.

  • You already experiencing issue that you wouldn't experience if you follow a standard workflow. (It also required a parser which could be a source of potential bugs)
  • You are under utilizing the engine performance and ease of use (Tilemap by example).
  • You are increasing the burden/increasing complexity of the designer/coder by adding additional conversion between the game and the designed level. This will impact the maintainability of the game as it grows.
  • You are increasing the potential load time of your game by a decent factor. If you ever want to make your game supported on mobile, that could actually be a real issue.
  • You will have a harder time to implement GPI in the future. By example, defining the damage of your trap or the timing of those.
  • You might not reallize, but the usage of such technique will undermine the artistic capacity of your team as they will not see exactly what they are doing.
#

You should really stick to a more standard workflow. The issue might not be obvious to you, but as you develop you might find yourself in situation where the choice you did really hurts. Even more if you are just starting. You havent even see what Unity as to offer and you already discard half of it.

#

One of the absolute force of Unity is its capacity to create tools and design level. You have a whole array of editor tools you can do and utilize to make the whole process of designing your level as painless as possible.

#

I will keep this in mind, and I will probably end up switching, but I have a few problems with it. First, I am the only person working on the game with any coding, composing, or gaming experience. I don't have a team, and I don't expect to have one. This is mostly just a personal project that others may assist with, but one that I want to get to a game that I'd be happy playing personally and one that I expect could grow to be a popular indie game in the future. I am trying to make everything as easy as possible to create, as adding 20 minutes to every level creation could easily add up to a few months in the long run. My original intent with this program was to allow me to utilize Unity's level design capabilities through a program so specific that it would likely only work on my game with my knowledge, but that would speed up an aspect of the game substantially. I admit that I may have lost that after being forced to compromise by having each pixel be an individual block rather than having the entire level be one object, so I may use the program as a blueprint that I can then create objects over, rather than the level itself. You brought up some great points that really made me realize how inherently convoluted this system is, so thanks.

I am happy that you are able to think rationally about it. It is rare to see people being able to make part of things. That being said, I believe that the current way you are handling things would actually be worst whenever your game start to take depth. If you have not explore the Tilemap, I highly recommend to look at it because it is the suggested way of doing 2D pixel art platform games. There is even things such as https://learn.unity.com/tutorial/using-rule-tiles that enable you to quickly create a level without needing to deal with corner and other special case tiles yourself.

#

If you want to delves into generative content, you could also look at Wave Collapse Function which enable you to automatically generate content for your game. The background/art could be generate with this while only the core of your game is being done by your designer. Saving an enormous amount of time. https://robertheaton.com/2018/12/17/wavefunction-collapse-algorithm/

What would be a best-practice setup for handling multiple variables in a burst job? I was thinking of using a persistent nativearray of structs that contains all my relevant values (position, velocity, forces, mass), but then I remembered it's bad practice to make structs mutable. What's the best approach here?

#

How does burst handle reads and writes at the low level? In this particular use case, wouldn't the fields just be offsets to the index lookup in the NativeArray?

sly grove
next marsh
#

I've just heard people recommend against it in C# (largely in newer versions), so I wasn't sure how much of that carried over to Unity and Burst

sly grove
#

Whatever you're describing I'd wrap all that data up in one blittable struct and use a Native array of them

next marsh
#

Awesome that's what I was thinking but I wasn't sure

sly grove
#

There's nothing wrong with mutable structs in this context and that's pretty much the main tool for manipulating data in jobs

next marsh
#

That's a relief-- and just just to confirm Unity.Mathematics' types are blittable right? (float2, bool2, etc)

sly grove
#

Yes

next marsh
#

Are NativeArrays safe to write in parallel?

#

I.e. If I have a parallel job that reads the struct in each index through some var myValue = array[index], performs an operation with the data in said struct, then writes the updated fields back to the array array[index] = myValue, will that piss the bed?

austere jewel
next marsh
#

Awesome, cheers

#

Is there anything to look out for in particular when choosing a specific inner loop batch count for a parallel job?

#

Like some power of 2 etc

#

Something that cleanly divides the array

clever urchin
#

Depends on how you're working with the data

#

Thread count, accessing patterns, etc

#

Benchmark it and see

#

But if you're iterating over the array, performing some operation and then updating that same value, theres a high chance doing it in parallel would thrash your performance

#

Because you'd potentially be jumping around and invaliding cache lines

scenic forge
#

From my understanding, it's pretty much a magic parameter depending on what the job is actually doing, that you need to tweak by trial and error.

any one good at math? My rotation function seems to not do what i was hoping it would do.

I am trying to rotate a point to the nearest X degrees relative to a directional vector.. this is what i tried:

/// <summary>
/// Rotate a point in discrete amounts relative to "axis"
/// eg: if axis is (0,0,1) (xz plane) and discreteAngle amount: 90, the point will be rotated in 90 degree increments (90,180,270..etc)
/// </summary>
public static void SnapToTangent(ref float3 pt, in float3 axis, float discreteAngle)
{
    // use radians
    discreteAngle = math.radians(discreteAngle);
    //get the signed angle between the point and the tangent vector (radians)
    var angle = signedAngle(pt, axis);
    //round the angle to the nearest discrete angle
    angle = math.round(angle / discreteAngle) * discreteAngle;

    // no rotation applied - skip the rest
    if (angle == 0)
        return;

    //rotate pt by angle
    pt = rotate(pt, angle);
    
    //using xz plane
    float signedAngle(in float3 a, in float3 b) => math.atan2(b.z, b.x) - math.atan2(a.z, a.x);
    float3 rotate(float3 a, float radians)
    {
        var sin = math.sin(radians);
        var cos = math.cos(radians);
        var x = a.x;
        var y = a.z; //i use xz plane
        a.x = x * cos - y * sin;
        a.z = x * sin + y * cos;
        return a;
    }
}

At the moment it doesn't snap at all

#

this gif shows it not snapping i used 90 degree angle with axis as (1,0,0)

Also, Unity code is:

        [MethodImpl(MethodImplOptionsEx.AggressiveInlining)]
        public static float Angle(Vector3 from, Vector3 to)
        {
            // sqrt(a) * sqrt(b) = sqrt(a * b) -- valid for real numbers
            float denominator = (float)Math.Sqrt(from.sqrMagnitude * to.sqrMagnitude);
            if (denominator < kEpsilonNormalSqrt)
                return 0F;

            float dot = Mathf.Clamp(Dot(from, to) / denominator, -1F, 1F);
            return ((float)Math.Acos(dot)) * Mathf.Rad2Deg;
        }

        // The smaller of the two possible angles between the two vectors is returned, therefore the result will never be greater than 180 degrees or smaller than -180 degrees.
        // If you imagine the from and to vectors as lines on a piece of paper, both originating from the same point, then the /axis/ vector would point up out of the paper.
        // The measured angle between the two vectors would be positive in a clockwise direction and negative in an anti-clockwise direction.
        [MethodImpl(MethodImplOptionsEx.AggressiveInlining)]
        public static float SignedAngle(Vector3 from, Vector3 to, Vector3 axis)
        {
            float unsignedAngle = Angle(from, to);

            float cross_x = from.y * to.z - from.z * to.y;
            float cross_y = from.z * to.x - from.x * to.z;
            float cross_z = from.x * to.y - from.y * to.x;
            float sign = Mathf.Sign(axis.x * cross_x + axis.y * cross_y + axis.z * cross_z);
            return unsignedAngle * sign;
        }

Why 3

#

What would the third point be

Because you need to have both vector ?

steel snow

You mean pt-origin and the axis vector

Hello everyone, I'm trying to make a pipe system for my 2D game, and I have the following problem: What is the best way to find if an object is connected to a specific object.

image.png
regal lava
#

Each object can contain a list of each connected object, and having that reference to that exact object you can then check if the list is empty or not.

tulip stump
#

wouldn't that be extremely slow?

#

I'm making this for a large scale multiplayer game, so performance would be good

tiny pewter
#

graph problem
you need a sparse set for storing the children

regal lava
#

Eh, I mean if you just need to know all parts of a single object, I don't see why it would.

#

It also depends how much would be contained in that list, and seeing your graph you seem to have a total of 4

tiny pewter
#

oh you may need a disjoint set

tulip stump
#

I see

tiny pewter
#

but disjoint set not support disconnect, not work if the pipe can be removed

regal lava
#

What you should be asking is what search algorithm you should be using to determine if a pipe is fully connected to the end

tulip stump
#

Yeah that's what I meant by that

tiny pewter
#

run bfs

regal lava
#

Like some sort of binary search, but really the best way to tackle this problem is to cache your positions

#

I guess it depends on how you want to design it. Now I'm kinda interested in making a pipe game haha

tulip stump
tiny pewter
#

you may run a star on it btw, it maybe faster than bfs, but heuristic is quite difficuly to define since you dont know how many gameobjects left (it can be treated as a graph of gameobject connects to other) to reach the target

tulip stump
#

I thought about A star, but that might break if there are many sources closer to the start than the actual source it's conected to, but I don't know

#

I'll try Bfs first

regal lava
#

Also that flood fill alg if you want to keep with the theme of plumbing ;)

#

bfs is honestly fine though, you're only checking this once per part placed

Hey can anyone help me with a rigidbody problem? I’m new to unity and I’m trying to make my rigidbody physics on my player work in the air so that they can maintain velocity and change the direction without accelerating. I can basically simplify the problem to this: The player is moving with a velocity with 0 drag and 0 friction, so they will just keep going if they don’t press anything. Assume the player already has velocity so they can’t speed up at all, just move around and maintain their current velocity (or stop if they wanted to). If they look in the direction of their velocity and A/D, they should turn, but maintain the same velocity. I also need to do this without manually setting the velocity, because that messes up other stuff, I just want to work with forces. The result should be that if the player is travelling forward, and presses D, they would slowly move right, making a curve until eventually they were travelling right with the same velocity as before.

#

here's an example, this is what would happen if the player is travelling forwards (north) and pressed D to go left (east)

flint sage
#

Add torque?

novel stump
#

oh ill take a look at that

#

could I use torque along with the player's current forces? @flint sage

flint sage
#

Yeah\

novel stump
#

Wouldn't that rotate the player as well? I just want to change their velocity. Like in the picture I sent, the player would still be looking north at the end if they hadn't moved their mouse

flint sage
#

Oh

obsidian glade
novel stump
#

like

#

across the sun

#

tangential

tiny pewter
#

circular motion

novel stump
#

but that relies on gravity from the sun, which in my scenario would mean gravity around an object to the right of the player, but depending on their input, which doesn't really make sense

obsidian glade
#

it doesn't quite, but the premise isn't too far off - the only direction you can apply force to turn without changing the velocity magnitude of velocity is perpendicular to your current motion vector

#

like a planet orbiting, the force is applied directly towards the point it's rotating around

novel stump
#

Basically I know that any force I add will need to be balanced, otherwise the player can accelerate which is not supposed to happen. I just cant find a way to balance the forces properly

novel stump
#

which I don't want. They should just maintain current velocity

obsidian glade
#

exactly - you need to apply the force perpendicular to the current direction of motion, at each point in time

tiny pewter
#

actually your velocity is changed that means there is some acceleration

#

ie dv

novel stump
#

yeah true I meant the magnitude increasing i suppose

tiny pewter
#

btw adding acceleration adding perpendicular to v have no work done iirc

novel stump
tiny pewter
#

that mean ||v|| will not increase

obsidian glade
novel stump
obsidian glade
#

(or add a check to stop adding the force when you're moving right already)

obsidian glade
novel stump
#

so you are saying that I don't need to add any force that acts against the player? I thought if I only add forces it will increase speed

novel stump
#

just realised

novel stump
tiny pewter
#

so you add acceleration perpendicular to v

novel stump
#

and then what if the player was holding A and D instead of just D?

#

still perpendicular? and just less force

tiny pewter
#

input handling is question for you

novel stump
#

so the force should stop when the player's velocity = their desired velocity depending on input

novel stump
#

if the player pressed S then of course they should slow down and stop basically. but if my forces are only perpendicular to current vector of motion how is that possible

#

I'm not talking about input handling but like their desired velocity basically (which is based on their inputs)

#

thanks for the help btw everyone

tiny pewter
#

actually if the ||v|| downs then the acceleration have to be decreased too to maintain the original radius

novel stump
#

this has had me busy for 2 days with 0 progress

#

i'm confused on how that would work in other situations tho

obsidian glade
#

intuitively I think something like forceFactor = 1 - dot([velocity vector you want to end up with], [current velocity vector]) would work reasonably well

#

(normalised vectors)

#

or simply a check to skip applying force when the dot is approximately 1

novel stump
#

what does the dot mean? sry

tiny pewter
#

i think you have to keep the acceleration vector magnitude until v dot original v is 0, otherwise the dv will keep decreasing in your case and it cannot maintain constant radius

obsidian glade
#

yeah, it depends what kind of turning motion is desired, I think gradually decreasing it might feel more natural, but either works

maybe when the player presses S it just adds a backwards force? along with the perpendicular for side to side

some people copy a mesh by grabbing the arrays which is very allocy

#

You can't copy something without mem copy or similar low level command. When people are "grabbing the arrays" they are doing a mem copy as well somewhere on the low level.

tiny pewter
#

Memcpy?

#

Besides, you can just copy the whole thing in one go if you're dealing with contiguous memory block, but most objects are not a contiguous memory block, so you can't just copy them in one go.

About the URP Sample Buffer - I'm trying to make my own post processing thing by following this tutorial: (it's timestamped to where he adds in the URP Sample Buffer)
https://youtu.be/9fa4uFm1eCE?si=ecwRgXs94eIy9LWs&t=1000

And I can see the logic in his shader setup, you want to add the values from the bloomed render texture into the "scene render texture" or whatever it's called at the time - but... I noticed I get a fully black screen when I try to visualize the URP Sample Buffer by itself - which points to... "Well, why does my node not give me the current texture?"

If anyone would know how to fix this, I'd greatly appreciate the help :v
Image
Image
Note - this isn't only a fullscreen pass - this stuff involved a lot of blit operations managed by code, and i don't fully understand those, so that could be where the problem lies at

(Deleting the duplicate from #archived-shaders, I didn't realize which channel I was at, initially, lol)

#

tldr; My URP sample buffer node is outputting full black, when I believe it shouldn't - how can I find my mistake?

Swapped out URP Sample Buffer to Scene Colour and... that's almost what I expected - but its ignoring several blit operations I made by code prior to applying my ben day dots

Ok so I've been trawling the forums and I found out that multiple cameras in URP have a huge memory problem due to constant releasing of render textures

#

Does anyone else have this bug?

sage radish
# rough sky Does anyone else have this bug?

I haven't had this issue but I've googled it a bit, and it looks like Unity has a texture pool to avoid allocation, but it defaults to a max size of 32 textures that can be "stale" at a time, as in unused but kept in memory. After this, it starts deallocating the textures, so they will need to be allocated again next frame.

Luckily, you can easily change this limit with the RenderingUtils.SetMaxRTHandlePoolCapacity(int capacity) method. It doesn't appear to be used by anything, like a setting in the URP asset which would be ideal, but it's easy enough to make a script that sets this value at startup.

#

Changing the value will deallocate the whole pool and reallocate everything next frame, so you should only set it at startup or between loading.

#

You'll want to raise this number until you see the allocations stop.

#

But obviously more video memory will be in use as a consequence.

hello guys, I'd like to create a procedural spawning system for a large terrain. I need to place objects on textures, but wonder how should I approach it.
First I created noise on texture then colored it above some threshold to green. Then I done such thing:
int textureWidth = textureToSpawnOn.width;
int textureHeight = textureToSpawnOn.height;
for (int x = 0; x < textureWidth; x++)
{
for (int y = 0; y < textureHeight; y++)
{
Color pixelColor = textureToSpawnOn.GetPixel(x, y);
// Check if the pixel color is green
if (pixelColor == Color.green)
{
// TODO: Find each pixel in worldspace (or localspace)
Vector3 spawnPosition =
}
}
}
...but can't find a way to locate green pixels in this approach. After I thought about it, maybe I could do that on a plane, but not a real terrain with a heightmap and so variable height I guess.
How should I do it efficiently? What I mean is having a texture mask with some colors (rgba) that would define areas to spawn specific objects

#

You can potentially cut out the texture middle-man depending on how you're generating it

How are you generating noise?

Can anybody offer some insight on this one. I'm using Cinemachine. In the following code snippet, I want the fade camera to take priority, fade out, then set the next camera to have the best priority (once the fade camera is back to 0). The problem I'm having is that the currentCamera and cameraToSwitchTo don't do their blend, before the FadeIn task starts. The blend doesn't happen until after FadeIn is complete, despite the fact that the "old" currentCamera IsLive.

public async Task SwitchToCamera(CinemachineVirtualCamera cameraToSwitchTo)
{
    currentCamera.Priority = 0;

    await FadeOut();

    cameraToSwitchTo.Priority = 1;

    do
    {
        await Task.Yield();
    }
    while (CinemachineCore.Instance.IsLive(currentCamera));


    currentCamera = cameraToSwitchTo;

    await FadeIn();
}

public async Task FadeOut()
{
    fadeCamera.Priority = 10;

    elapsedFadeTime = 0.0f;

    do
    {
        elapsedFadeTime += Time.deltaTime;
        fadeStoryboard.m_Alpha = Mathf.Clamp01(elapsedFadeTime / fadeDuration);

        await Task.Yield();
    }
    while (elapsedFadeTime < fadeDuration);
}
public async Task FadeIn()
{
    elapsedFadeTime = 0.0f;

    do
    {
        elapsedFadeTime += Time.deltaTime;
        fadeStoryboard.m_Alpha = 1.0f - Mathf.Clamp01(elapsedFadeTime / fadeDuration);

        await Task.Yield();
    }
    while (elapsedFadeTime < fadeDuration);

    fadeCamera.Priority = 0;

there is no way except you hard code all the names of each element (since i think there is no function that given the atomic number it returns the name of the element), perhap you can have file io (read from json) but you still have to hard "code" the names

vague quail
#

it's not a problem hard coding all, my question is related on readability from machine and time expenses

#

i will hard code all the informations and then commenting with human details

#

so is the dictionary the best way to do this?

#

if your game use atomic number then i think you can use array, but no one (at least from those who are not chemistry major) will remember atomic number<->element number name conversion so use dictionary is fine

So I've created this ability where the player can change the direction of their gravity to whichever way they face when the button is pressed

That part works fine. But I want to make it so it will rotate the player so the bottom is pointing in the direction of the gravity so they can walk on the walls and ceilings.

I've tried a few things already but haven't gotten it working well

I have a Vector3 that is what sets the global direction of the gravity. I just need to know how to point the feet of the player in that direction. Also I plan on having it smoothly lerp the rotation after I get the basic thing working

Hey, quick question that's very important right now.

While using compute shaders with render texture 24bit depth, RFloat format it works flawlessly on android api level 28 (android 9), but on api 24 (adnroid 7) it does not work. Both devices with supported GLES 3. Any change in format or depth results in rendering fragment of screen instead. Compute uses RWTexture2D<float>. Output written to RWTexture in my case is in range of float 0~1

What can i change to make it run?

Hey so is there any way I can either compress or emulate compression of a rendertexture? I need it because I have to be able to create a 16k atlas on the fly on the GPU, which means I need to use a compute shader to create it, but even at rgba32 that rendertexture is 1 gig, which is just too much... I know they cant really be compressed in the sense texture2ds can be, so do I have any other options?(This is all because unity doesnt support bindless, so my only way of sending an unknown amount of texture to a compute shader at once is to pack them into a single huge atlas)

untold moth
honest hull
#

I need to be able to do it frequently, without causing a massive stutter
And yeah the amount of vram

untold moth
honest hull
#

Whenever an object is removed or added from the scene I need to add its textures to the atlas

#

So that I can render it from the compute shader, which means I need it’s texture

untold moth
#

Why not load it at the game/level load time?

#

Also, if it's one object, surely you don't need to upload the whole 16k atlas again?

#

Not to mention that I'm a bit sceptical about rendering from the compute shader🤔

#

Donno your use case though.

honest hull
# untold moth Donno your use case though.

Pathtracing in shader, I need to remake the atlas to include the new texture
And it can’t be constant as I don’t know what objects may be added or removed over the lifetime of the scene

untold moth
honest hull
#

So I am trying to find another way that doesn’t require cpu side to reduce vram

untold moth
#

So it is a matter of vram consumption after all?
I'm not sure if there are ways to compress the texture on the GPU. And there's probably no way to compress a render texture either, so you'll probably need to think of something else.

honest hull
#

Hmmmmm

untold moth
#

Maybe someone else has a better idea. What you do requires some intimate knowledge of graphics API.
There are probably more options with low level API.

Uuggghhh ok
There’s not really any way to compress it tho

Yeah I know, but unity doesn’t expose most of the really useful things you only sometimes need

As a way of optimising my three camera set up, I am using one camera, and every frame setting the culling masks and target texture by code and calling Camera.Render() to invoke the effect manually for each of the two extra cameras.

However, camera.render() seems to have more attached to it than just rendering, for instance it invokes all the attached render functions. Is there a more optimised Camera.render() that bypasses the extra things like this?

Ok here's a thing. I have a project in which I use Addressables to load content scenes into my main application. The content scenes contain slideshows and videos. Now, I want to reference these slides and videos by URL. To make it easier for content creators to place the videos and slides in the scene, I created a proxy component that just takes an array of Texture2D or Video files.

I then have an editor script that takes the arrays and uploads the videos from the Unity project onto the data server.

BUT as the proxy component still references the array, the Addressable bundle also contains these videos.

Does anyone have any tips how I can keep that UX for the content creators to just drag and drop their textures into a proxy component in the scene?

#

Here's an example of my proxy component. It sits on a scaled Quad positioned in the scene where the slideshow should be.

How can I have LifetimeScope on a prefab when using IObjectResolver.Instantiate ?
Looks like when I use this method, actually it registers LifetimeScope component too (Because of registering the root gameObject and all the descendents) and it makes an error on the parent which calls instantiating.

Need to think about it. At a Minimum it adds complexity due to nesting, and while that may not be a problem in some cases it could be very confusing in others, especially absent clear documentation in the codebase how they are to be handled. Containers in unity typically get very dangerous in teams where not everyone is an expert in keeping things simple and the benefits of DI. So if you extrapolate what you try to do to a team situation, you will probably find reasons for VContainers opinions. I think by and large DI with vcontainer is easiest if you avoid MonoBehaviour controlled lifetime scopes as much as possible.

#

Anyway, nested scopes shouldn’t cause issues.

#

Resolving dependencies by directly accessing the container would be quite wrong (in principle) and vc doesn’t like it.

In my case it doesn't look very complicated. Each player (2 players in total as a local coop game) and each has 2 characters. Characters have DI for own components and their children. Just instead of creating them in facade class I inject them by VContainer.
Also no direct resolving.
Probably I should check non-MonoBehaviour LifetimeScope. But I don't get why gameObject injection doesn't ignore LifetimeScope. I think the issue I have is because of that.

Well, a DI container only really works well if it handles all instantiating statically (I.e. all dependencies can be resolved at any time without any late registration once the composition root was built). This means no object can be allowed to survive its parent scope or init/install before it’s parent has finished installation. Manually instantiated objects (like you often have in a game) aren’t it’s forte.

is there any way to make it so I keep the sampling speed of a texture2d but in a rendertexture? I REALLY dont want the extra 2 gigs of VRAM/RAM from the 16k texture2d atlas, and the amount of time it takes for creating that new texture, and then doing Graphics.CopyTexture from the rendertexture to the texture2d(I make the atlas on the GPU because its MUCH faster)

west scarab
honest hull
#

in a compute shader, incoherently

west scarab
#

I'm surprised it's 4 faster

honest hull
#

mhmmmm

#

it succkkksss

#

means I need to still do the render texture things, copy to a texture2d(which means its now a 2 gig texture) and then release the rendertexture

honest hull
#

anything I can really do?

west scarab
honest hull
#

rgba32, so 8 bytes per component

#

thats the smallest I could go for an albedo tex

west scarab
#

Does your texture2d have mipmaps?

honest hull
#

no

west scarab
#

Is it compressed?

honest hull
#

cant compress it
not only would that cause a large stutter whenever I need to remake the atlas, I need the data thats on the GPU (from using Graphics.CopyTexture from rendertexture to texture2d) to be on the CPU otherwise it clears it

west scarab
#

I'm just trying to figure out where the performance difference is coming from

honest hull
#

ohhhhh for that

#

idk
I think its just in general incoherency
neighboring pixels have basically no chance of sampling nearby pixels on the texture

#

and its a 16k texture

west scarab
#

Are your rendertexture and texture2d the same memory size overall? I assume they have the same resolution

honest hull
#

yes
both are 1 gig in inspector

#

yes theres a lot of empty space there but thats mostly cuz I dont have enough textures in current scene to fully fill it, but in most scenes this is not the case

west scarab
#

No idea what the issue is. Only thing I can imagine is they are stored differently in memory somehow making it slower to read from a rendertexture than a texture2d due to cache misses

honest hull
#

yeah 99% sure they are...

west scarab
#

Then there's probably not much you can do. RTs are probably optimized for writing, not for reading

honest hull
#

uuuuggghhh ok
guess I have to eat the huge ass RAM/VRAM cost for the texture2d then since I dont think I can compact it any smaller?

dusty wigeon
honest hull
#

yes as its an atlas that contains all textures in the scene, as thats the ONLY way to send an unknown amount of textures to a compute shader at once

#

I hate it but its the workaround I know of for no bindless

dusty wigeon
#

Does not really seem viable

honest hull
#

no other option

dusty wigeon
#

You could try to descrribe what you are trying to do.

#

Maybe someone has an idea

honest hull
#

ok
Basically what I do is I take all the albedo textures of all objects in the scene and aggregate them into a single atlas(theres a bunch of other stuff I do to allow me to access them nicely, but thats not important to this I dont think), as this is the only way to send an unknown amount of textures to a compute shader at once in unity
This single atlas needs to be able to be completely remade in a single frame without massive stuttering so I build the atlas on the GPU with a compute shader
Thus that means that it needs to be a rendertexture, however rendertextures of these sizes are horribly slow to sample for me, so I need to turn it into a texture2D which I do
So my resulting issues at this point is that this resulting texture2D takes up 1 gigabyte on the GPU and 1 gigabyte on the CPU, which I really really dont like...

dusty wigeon
#

Basically what I do is I take all the albedo textures of all objects in the scene and aggregate them into a single atlas

This is not scalable in any way. You are going to hit a wall really fast.

#

Why you want to do that ?

honest hull

because there is no other option
no bindless
texture arrays are out because they only allow same sized textures
etc.

dusty wigeon
#

What is the requirement that force you to do that ?

#

There is a reason why you want to do that.

honest hull

that I need ALLL these textures in a compute shader

Why ?

#

What you are doing in the compute shader

beacuse what I am making is a renderer that runs in a compute shader

#

I have no knowledge of how pathtracing should work. However, base on the fact that HDRP does pathtracing, I am pretty sure there is other alternative.

I have an AudioSource that I'm playing a "combo" sound effect on. Since I'm orchestrating it outside of my audio service, I have a delay on it with a DOVirtual tween:

        public static void PlayComboClip(AudioClip clip, float delay) => Instance.PlayComboClipInternal(clip, delay);
        private void PlayComboClipInternal(AudioClip clip, float delay)
        {
            _comboClipTween?.Kill();
            _comboClipTween = DOVirtual.DelayedCall(delay, () => PlayComboClipImmediate(clip)).Play();
        }

        private void PlayComboClipImmediate(AudioClip clip)
        {
            if (_comboSfxSource.isPlaying) _comboSfxSource.Stop();
            _comboSfxSource.PlayOneShot(clip);
        }

It works fine but it's a little abrupt - I'm thinking maybe I want to fade it for a tiny amount of time if it's already playing before playing the next one?

Is there something in UnityEngine.AudioSource that could maybe assist with this? I can't really easily insert a new callback into the tween (since it's already playing)..

the combo sounds can be 2-3 sec long, but moves can be done pretty rapidly - like 0.5sec - so they overlap in a kind of nasty way (without the above)

#

Also a lot of legwork for this.. feels like something should be in AudioSource but I didn't see anything

#

I could maybe also create audio sources for these SFX at runtime and just tell themselves to fade and destroy themselves after playing, but I think that's probably going to incur other problems

#

seems like it works well enough?

Anyone know how I would go about calling a function from an instantiated component in unity from a script outside unity?

sly grove
#

I don't see how "from a script outside unity" is really relevant to the question

#

to call a function from an instantiated component, simply save a reference to it and call the function on the reference

#

for example:

public MyScript myPrefab; // assign in the inspector
MyScript theInstance;

void SpawnTheThing() {
  theInstance = Instantiate(myPrefab);
}

void DoTheThing() {
  theInstance.Whatever();
}```
polar orchid
#

I have a process running outside of unity that'l need to call specific functions within the unity process

sly grove
#

I know that

#

you said that

#

That part isn't relevant to the "function from an instantiated component in unity" part though

polar orchid
#

Well I cant just call instantiate in another process can I?

sly grove
#

No but I didn't know which part of the problem you solved

#

and which part you wanted help with

#

I assumed the "call a function from another process" was the part you already knew how to do

#

and you didn't know how to call a function on an instantiated object

polar orchid
#

Oh, no lmao the opposite, that's the hard part for me calling a function from a different process

sly grove
#

Ok, your extraneous details confused me.
Your options depend on what platform you're on

polar orchid
#

Preferably desktop, WebGL can also work as I'm pretty sure it has a JS hook api

scenic forge
#

You need to establish some sort of interprocess communication, doesn't matter what.

sly grove
polar orchid
#

Yeah ideally on desktop I can get some sort of interprocess communication, do you have any idea on how I can achieve this?

polar orchid
#

?

sly grove
#

TCP is one pretty universal option

polar orchid
#

as in establish some sort of websocket connection?

sly grove
#

not websockets

#

just a TCP connection

#

websockets implies web browsers

polar orchid
#

ahh, didn't know, had a multiplayer game that used websockets as a transport but it worked both in webgl and in a desktop build. But yeah the TCP connection seems like a good idea

#

Thanks :)

sly grove
#

websockets is HTTP based which adds a lot of complexity

#

TCP is a lot simpler

polar orchid
#

Ahh great, would you happen to be able to point to where I can find out more about tcp connections in unity, or would just googling "Unity tcp connection" suffice

sly grove
#

Unity is basically not relevant

#

more like

#

C# tcp listener

#

just run one of those in a background thread from unity

#

and make sure you understand multithreaded programming enough to have that background thread interact with the main thread as needed.

scenic forge
#

(I've also seen terribly written software that don't know how to do IPC properly, so they use a temporary file and read/write to it to communicate... Please don't do this, but if you must, that's an option 😅 )

polar orchid
#

Does it necessarily need to run on different threads? This won't be client facing so some lag would be fine

sly grove
#

lest you block the main thread and therefore tank the framerate

#

You can't use tcp listener in the unity main thread unless you don't care if there are literally no frames drawn

polar orchid
#

Ok cool makes sense thanks a lot for the help!

I mean, this is definitely the best way to achieve whatever you want. I really doubt that you are going to find what you want out of the box.

sage radish
# distant kernel hello friends. i am trying to sync indices of a List of objects and a sphere arr...

You can remove elements by swapping them with the last element in the list. Then you only need to update one element in the array to keep things in sync.

For example, if you have a list of integers: 1, 2, 3, 4, 5, and you want to remove number 3, you swap number 5 in its place: 1, 2, 5, 4. You did mention you didn't want to break the order, but you didn't explain why that's important. I can't see why that would matter here.

How can I create this splash effect in the background? (The juice of the food in the background and disappearing with time). What technology should I use? The particle system? A gameobject with a sprite that just changes the opacity from 1 to 0 with different dimensions every time?

Since you asked, both a particle system or sprite should be fine, particle system could be faster, depends on how many decals you want.

#

I would just benchmark it if you are concerned

indigo citrus

So how would I do the different splash every time with the particle system? With sprites I would just have 9 different sprites or something... But what about the particle system?

west scarab

#

Yeah

west scarab
#

You can use a spritesheet, and then set an index

dusty wigeon
# graceful widget Hi, I've actually been struggling for another week, but do you have any ideas/ma...

You are struggling at the moment because you are trying to come up with a system before having defining the specifics. The easiest way, is to implement a few abilities then compare whatever they have in common. With experience, you would be able to reduce this step.

That being said, there is something important that I learnt from experience which is the distinction between an instance and the concept. It is similar to the difference between an instance and a class. An example, would be that if you to a market to buy a fish, there is actual two distinct type of fish. The fish that you intended to buy (the concept, price - name - brand), and the actual fish (the instance, weight - smell - look). This directly relate to what you should do with your ability. In my project, I use "Definition" of diverse object to represent the concept. The actual instance is being created in runtime whenever needed either with C# object or GameObject.

I took an hour to make something that represent what I meant by definition (Implementing a Fireball ability in a "generic" way). (Not tested) At the end, this is only an example of what it could looks like. You need to acquire experience and the ability to quickly pivot from one architecture to an other. As your game evolve, your architecture needs to evolve as well. To come back to what I said at the beginning, you should start by implementing a few ability then look what is coming back often. From there, this is a question of applying what you know about design pattern and programming principle.

You need 1 precompile on the actual class. You can then use reflection if you want afterwards for the "injection" or an other preprocessor directive. Dependency injection is definitely a way, however you absolutely need preprocessor directives.

Did you use the profiler ? You might be able to see additional information then the build file. The other alternative would be to delete part of the project one by one to see what is the cause of the slow build. It might also be totally normal depending on what you are building. Finally, if you havent or have updated, you could try to change Unity version between 2022 and 2021. There is a lot of additional performance optimization in 2022 that might be the cause or that could help.

I am trying to write some code that can be called to return a list of tiles on my map when they player needs to target an ability. I need there to be functionality for the game to continuously highlight tiles that the player mouses over but only return the tiles when the player clicks, obviously this while loop is problematic and I was wondering if this is a case where I should be using an async await implementation, is that the case and if so does anyone have any pointers on how to achieve that?

public Tile[] TargetTileSquare(int size)
    {
        targetTiles = null;
        playerInputState = InputState.Target;
        while (targetTiles == null)
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out RaycastHit hit))
            {
                Tile temp = hit.transform.GetComponentInParent<Tile>();
                if (Input.GetMouseButtonDown(0) && temp != null)
                {
                    targetTiles = new Tile[] {temp};
                }
            }
        }
        playerInputState = InputState.Inspect;
        targetTiles[0].Highlight();
        return targetTiles;
    }

I'm trying to have a stack where my Unity client is authenticated by my .NET Core server which retrieves auth tokens from Azure AD. Has anyone ever done this before?

#

Like is it possible to have a server middle man which authenticates my Unity client, and is able to get resources on behalf of the Unity client from Azure thereafter? I'm thinking:

  1. Unity hits server with a login/register request.
  2. Server authenticates with Azure AD, and then returns token to Unity client.
  3. Unity client sends subsequent requests with the token to the server.

#

the problem is that they want TargetTileSquare to return a list of tiles

#

meaning that it would have to block until the player actually picks the tiles

dusty wigeon
#

I mean, the mouse cant move in a while loop not threaded,

bleak citrus
#

I suppose you could do something with async here (maybe using Awaitable to check the currently-hovered tiles every frame on the main thread)

dusty wigeon
#

Isnt the best to have a picking up state ?

#

With an update loop.

bleak citrus
bleak citrus
#

the ability would not be waiting for the player to pick a target

#

picking a target would signal the ability to start

#

that's how I handled this in an RTS

dusty wigeon
# 
private Tile[] targetTiles;
private bool tryingToPickup;
private boo hasPickUp;

public void Update()
{
  if(tryingToPickup)
  {
      targetTiles = null;
      playerInputState = InputState.Target;
      Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
      if (Physics.Raycast(ray, out RaycastHit hit))
      {
          Tile temp = hit.transform.GetComponentInParent<Tile>();
          if (Input.GetMouseButtonDown(0) && temp != null)
          {
              targetTiles = new Tile[] {temp};
              hasPickUp = true;
          }
      }
      
      playerInputState = InputState.Inspect;
      targetTiles[0].Highlight();
  }
  else
  {
    //Handle other state such as choosing the ability to cast
  }
}
stiff widget
#

I should have explained a bit more, this is a card based game so this implementation is for the logic for a card being played and then the player selecting targets based on what card was played

stiff widget
#

your solution could work where the function just flags the tryingToPickup bool

dusty wigeon
stiff widget
#

I think i was struggling to visualize how the functions would control the code in update but seeing your visualization i think that would work

#

do you think that this would run in to issues if for example a script to play a card that had multiple targets had to call the target function more than once and then perform an operation with the results of both functions? (basically do i need to do these things using async?)

# regal olive I'd like to expand on <@307360612403642370> 's answer. It seems like you are try...

What if one of the types I want to reference is a prefab? I'm currently using the struct that I later on serialize so that I can drag a prefab into a struct field and use it to instantiate objects from a factory. Could I perhaps use Unity Editor to drag the prefabs into a List<T> and then use Bakingsheet to serialize the records into a JSON that I can import to the unity editor and also use during gameplay once the game is built?

weak monolith
#

Does anybody know if there is any significant overhead in using scriptable objects as global variables that other scripts modify through unity actions?

#

for example, multiple scripts having a copy of the SO listening for a unity action/event that passes variables from a boradcaster > channel > listener chain type of thing?

sly grove
weak monolith
#

It's more a general question about if there are any issues doing it that way since SO's can act a bit strange sometimes (for example, storing info only during run time but not being able to write to the SO).
So basically there is an SO that waits for someUnityAction?.Invoke(params). If there are say 50 objects with that SO "listening" for that event, does it cause any issues? Haven't profiled it because in terms of perfromance, HDRP takes up the lion's share of ms. It's more that I don't want to start implementing it only to find out it has a huge footprint in memory or it isn't garbage collected etc.

sly grove
#

I'm not even sure I understand what you're describing with 50 objects having the SO listen to an event

#

Show an example perhaps?

#

As for strangeness, there's not a lot of strangeness with SOs, they pretty much behave exactly like any other Unity asset

#

Don't change serialized data on assets in the editor or it will be permanently changed

weak monolith
#

public class NPCChannel : ScriptableObject{

public UnityAction<NPCEvent> npc_event;

public void RaiseEvent(NPCEvent _event) {
    npc_event?.Invoke(_event);
}

}//EO NPC channel

sly grove
#

So that's a regular delegate, not a UnityEvent

#

It works like a normal C# delegate, because it is one

untold moth
#

It would work exactly the same as a plain C# class in terms of performance.

weak monolith
#

awesome. Is there any real benefit to having it in an SO?

untold moth
#

You can drag it around in the editor.

sly grove
#

You can reference the SO as an asset

#

That's the point of SOs

weak monolith
#

would it be better as just a C# class that other scripts reference?

sly grove
#

If you don't care about referencing it in the editor

untold moth
#

If you don't need to reference it in the inspector, sure.

weak monolith
#

haha, thanks!

sly grove
#

Unless it's intentional that you can invoke the delegate from outside that one function

#

You can also just use System.Action

#

UnityAction doesn't buy you anything

weak monolith
#

yeah I'm not sure what that means but the RaiseEvent is called by multiple scripts, but the action itself is only in this script

sly grove
#

Right so

#

Putting event on the delegate will ensure that it can only be invoked by calling that function

weak monolith
#

like public event UnityAction, or in the method RaiseEvent? I never studied coding, self taught.

sly grove
#

The first

weak monolith
#

Thanks for the info 🙂

untold moth
#

If anything, programming is all about self teaching.

weak monolith
#

Hahaha, I'm an "old fella". There's not as much room in my brain as there used to be, but I get by. Moving through different paradigms is hard though - like data oriented design. Can't wrap my head around that yet 😄

untold moth
#

Nvm. Misread the message 😅

light falcon
#

what would be a good way of decoupling code? I was thinking of using a system with a general 'events container' script, example: Script A wants to trigger an event, so it calls the event in the events container (script B), which script C is subscribed to. Is this a good approach? I like to hear your opinions!

untold moth
#

It depends on the situation. You don't always need to decouple code entirely. Sometimes one way dependency is what you want.

in what cases would you want dependancy?

Indirection makes things slower and more confusing to read

What you are describing somewhat sounds like just moving events from one script to another. Theres no real change happening, except now its actually harder to setup things.
Let's say you have a bunch of buttons and a bunch of doors in game. Each button opens 1 door, this is very easy to setup with unity event and a public method on the door.
Now if you change this to go through your events container, you'll need to find a new way to link these objects so that 1 button event doesnt trigger every single door. You could do it based on ID but now this introduces more work for the same outcome

light falcon
#

i see. But for static events this would be a good choice?

vale basin
#

(I don't know if this belongs to "code advanced", sorry in advance)
I generate frames and store them in individual interleaved byte arrays where each byte is a color channel (3 bytes / pixel), how can i use GetRawTextureData and write to it in this case?
My current approach is to use LoadRawTextureData and provide it my byte array

redirected issue from #🏃┃animation since i was advised to come here:
i've been trying to make a tool to convert animations from one reference position/rotation to another, so i can make my process of making third person animations way faster. in idea, it's simple. get rotation/position values from an animation, subtract them by one reference position/rotation (or in the case of quaternions, multiply the inverse), add another reference position (aka multiplication with quaternions)

however, in practice what happens is gimbal lock. what i'm doing is getting the euler rotation values from the animation curve keyframes, assembling them into a euler vector3, then when i need to edit them i convert them to quaternions, convert the clip reference rotation and the new reference rotation to quaternions, then do my calculations with quaternions. then, when i create the new keyframes for the output animation, i convert them back to euler. i am doing no calculations with eulers, only using them to get and add values to an animation.

despite this, i encounter gimbal lock. i do not know how to circumvent this and would like to know what i'm doing wrong. also, i tried setting interpolation to quaternion on the animation and it resulted in this weirdness:

Trying to create a procedural mesh for a fibonacci sphere is a pain, but UV mapping it correctly seems flipping impossible

#

I always end up with this weird pinching effect along a seam. I thought it was because I had triangles passing over the seam, and yeah the "u" value on the triangles with that messed up UV also have an average U value of around 5 if you average its 3 points

#

I'm using this method to make a procedural rock. Fibonacci spheres seemed like a good idea because of how they generate evenly distributed points which would be good for applying noise. But once I got to actually using a spherical projection for UV, I can not for the life of me get rid of this artifact

            for (int i = 0; i < vertices.Length; i++)
            {
                Vector3 vertex = vertices[i].normalized;

                // Compute the azimuthal angle (theta)
                float theta = Mathf.Atan2(vertex.z, vertex.x);
                if (theta < 0.0f)
                    theta += 2.0f * Mathf.PI;

                // Compute the polar angle (phi)
                float phi = Mathf.Acos(vertex.y);

                // Convert spherical coordinates to UV coordinates
                float u = theta / (2.0f * Mathf.PI);
                float v = phi / Mathf.PI;
                uvs[i] = new Vector2(u, v);
            }

            return uvs;
        }```

            var uvs = GenerateUVs(vertices);
            var convexHull = GetConvexHullFromPoints(vertices);

            var mesh = MeshFromConvexHull(convexHull);
            mesh.vertices = vertices;
            mesh.uv = uvs;

Are you the same cathei who is the creator of this tool? I'm very interested, but if you had a video tutorial on how to install it and implement it in a simple project, it would be awesome. As an example, I had never used Dependency Injection, but I was very interested in using it with unity. The creator of AlchemyBow (https://www.alchemybow.com/) made documentation available as well as a very short series of videos on his YouTube channel. He made it incredibly easy to visually follow with explanations, and within 2 weeks of refactoring my code, I am fully using his DI framework in Unity and loving it instead of using singletons. The documentation is still 100% the source of truth, but simple video guides go a long way in promoting adoption of a new tool. Thank you if you are the same creator who posted in the Unity Forum and Reddit in the past 2 years.

Can any one explain why this gives me an array larger than the the total assets in the file:

        void LoadMeshAssets()
        {
            _meshes.Clear();
            var objs = AssetDatabase.LoadAllAssetsAtPath(_meshAssetPath);
            Debug.Log(objs.Length);
            foreach (var obj in objs)
            {
                if (obj is Mesh)
                    _meshes.Add(obj as Mesh);
                Debug.Log(obj.name);
            }
        }

it returns 12 for length and seems to load the same mesh file multiple times

there isnt 12 assets in the file

It says "Buffers and textures are set per-kernel." for ComputeShader.SetBuffer
does that mean that every SetBuffer will create a new buffer for each kernel even if I use the same ComputeBuffer object every time ?

#

just trying to come up with the optimal way of managing data between multiple kernels
there's a big chunk of data that is common between all of the kernels, and smaller chunks of kernel-specific data
if SetBuffer is smart enough to create one instance of a buffer and just grant read access to multple kernels, I'll keep that static data separated
and if not, I want to just piggyback kernel-specific data with the static data

# vivid vapor redirected issue from <#502171313201479681> since i was advised to come here: i'...

What are you trying to do ?

  • You want to add an offset to an animation ?
  • You want to add IK to an animation ?
  • You want to add an animation on the already defined animation ? (Additive)

Also, by the documentation:

Quaternion interpolation rotates the GameObject across the shortest distance to a particular orientation. For example, regardless of whether the rotation value is 5 degrees or 365 degrees, the GameObject rotates 5 degrees.

Which could definitely be what is happening.

I sugges you go over the Charaction Action series by Tara Doak.
'https://www.youtube.com/@TaraRaeDev/search?query=character action'
Before starting I suggest going over the entire series and taking notes from each video.
Initially you will feel overwhelmed but repeat and try to understand what problem each design decision solves.
If you have any alternate ideas which you think would solve the understood problem well, try it first and then continue. That will give you nuanced ideas regarding implementation details which @dusty wigeon also suggests. I highly suggest not copy pasting. Hope this helps.

#

can anyone recommend a site with common terrain noise functions ?
some sort of height function database or cheatsheet ?

compact ingot
rugged radish
#

so I don't start from scratch

compact ingot
#

you should maybe download gaea and world machine demos and play around with them

#

just to get a feel for the functions

rugged radish
#

thank you, I'll have a look

compact ingot
#

you can waste a lot of time with terrain generation, its a rabbit hole

rugged radish
#

yeah, I understand that 😄

#

it's also pretty fun

regal lava
#

fastnoise is life

compact ingot
#

a productive approach is to make yourself some custom stamps with those generator apps and then use something like microverse or your own tool to build your actual game terrain with them

#

procedurally generating a full terrain with various landforms and biomes that look interesting is extremely difficult and time consuming

rugged radish
#

right, you reminded me of terrain stamping, I should add it to my to-research list

compact ingot
#

also you need a beast of a CPU to actually make such a terrain at a usable resolution

#

also consider that unity is terrible for world streaming

rugged radish
compact ingot
#

basically you can't make large maps in unity without a lot of pain and suffering in terms of workflow/design/authoring-experience

rugged radish
#

I made a basic scrolling terrain "engine" and now in a process of writing the lanscape compute shaders

#

so far I'm only generating a 1.5km by 1.5km "window" on the fly at high resolution, with the rest of the world being pregenerated at a 1:16 resolution (for the lowest lods)

compact ingot
#

that sounds like a reasonable size in unity

regal lava
#

I was writing some terrain generation in OpenGL, but the problem with doing it like that is having to develop the UI, so I had to keep recompiling the damn thing every time I wanted to change up the noise map. Unity is a godsend for this type of stuff, being able to compile it on the fly while sliding the settings.

#

Still, I'd spend hours trying to get it looking semi-decent looking

compact ingot
#

you can take a look at world creator (standalone app) that does terrain entirely on the GPU

#

from what i've seen GPU approaches so far generally fail to produce interesting landforms (those can't easily be implemented as pipes&filters) , but are great at generating local details quickly

rugged radish
#

yeah, I moved everything on the GPU, tried generating in unity jobs first, but it was slower than I hoped

compact ingot
#

GPU is very limited in what it can do, even though its fast, you are constrained to using closed functions (if you want to retain the parallelization advantage)

#

unfortunately, interesting terrain can't be generated that way

#

you can however use the GPU to put details on a landform you've generated by other means

rugged radish
#

so far the plan is to pregenerate the "skeleton" on the world creation step on the cpu, and use gpu to evaluate it at play time

regal lava
#

I'd just do everything in a vertex shader and just bake the colliders after. GPU is just too good to pass up for a job like generating the thousand of verts and normals.

rugged radish
#

it's not an infinite terrain, so I can construct a graph and mark up the map
but it remains to be seen how good the end result can be

compact ingot
#

how expressive do you want the terrain to be?

#

just some random hills or do you want actually impressive scenery?

rugged radish
#

good question, I don't plan for realism, so it can be less strict overall, but ofc I want scenery to look exciting to explore

#

"just hills" won't cut it 😄

compact ingot
#

thats probably going to not happen

#

^something like this is never going to come out of a proc-gen terrain

rugged radish
#

oh, for sure, I don't plan to compete with hand-crafted terrains, I understand the limitations
it has to be decent enough, and since my intention is stylised look it should make things a little easier, I think

compact ingot
#

for sure

regal lava
#

Just keep throwing noise maps at it

#

eventually it'll look good (or worse)

#

good read

compact ingot
#

to make actually interesting terrain procedurally you need to actually simulate the tectonic-folding/volcanism/glaciation that forms mountains/hills

#

the trickery you can do with fluvial/sedimentation sim and noise can never really get there

#

they are stochastic, so you'll always get something thats is "meh", i.e. it hints at what it could be, but it will never produce these show-stopping artefacts you get in real life

#

a stochastic neighbourhood will always be similar to all other neighbourhoods, so no surprises, and those are what makes exciting terrain

#

I do intend to use the pregenerated world graph to define the irregular shaped domains for different types of landscape

like separating mountain ranges, riverbeds, different types of "flat biomes" etc, so I hope it won't be boring, but yeah, I will only see how it works once it works

regal lava

I think instead of all this

 _enemyMovement = new EnemyMovement(transform, _navMeshAgent, enemyConfig, _enemyAnimator);
            _enemyAttack = new EnemyAttack(_bombController, _enemyAnimator);
            _enemyDeathController = new EnemyDeathController(_navMeshAgent, _enemyCounter, _ragdollController, _colliderController, _coroutineRunner, enemyConfig);

            _enemyStateMachine = new EnemyStateMachine();
            _enemyStateFactory = new EnemyStateFactory(_enemyStateMachine, _enemyMovement, _enemyAttack, _enemyDeathController);```
Perhaps just make like an Assign(); function. But otherwise doesn't seem like that big of a deal if it works ;p
compact ingot
#

unless you have a reason for abstracting object creation into a separate class (i.e. because it needs to be an open design space that is very likely to change on the authority of another team) you are overdoing it.

#

if you are doing it because of dependency injection / IoC, do what Mao says, make a Inject/Assign/Configure method

#

if you are doing it because you are using a DI container, try to use one that allows you to create ad-hoc factories with delegates in the composition root

Minecraft is actually a good base for how to generate pretty expressive and varied terrain. Their aproach is rather interesting, and its definitely worth giving this talk a watch. In essence though. it's always going to be about how good at manipulating noise you are. https://youtu.be/ob3VwY4JyzE?si=Z457DZ9PvppdNiiW

Reinventing Minecraft world generation by Henrik Kniberg

The past year and a half I've worked almost full time with Minecraft world generation. We've radically changed how the world is generated, to enable dramatic new caves, massive mountains ranges and overall more natural-looking terrain.

In this talk we'll geek out on the gory details of this. How does Minecraft procedural world generation actual...

There are minecraft specific details that are irrelevant to you, but the overall structure of their system is useful

Does anyone know how to go about using a different thread than the main one and use marching cubes to create terrain. so far i am creating terrain with maching cubes and noise but i want to move that process off the main thread so i am creating triangles, vertices, uvs and then passing the data back to the main thread but when i do everything is messed up. also if i run the same code only using the main thread everything is fine

image.png
flint sage
#

That looks like multiple threads are appending to the same collection at the same time

#

So the order is all messed up

#

You need proper locking for that or give each thread a section to work on and a section that it's allowed to write to

#

So that nothing overlaps

royal raft
#

thanks if you mind what is locking ive never heard about that before?

tiny pewter
#

i remember c# collections will throw exception when >= 2 threads try to write at the same time

flint sage
#

Just look up C# locking

royal raft
#

ok thanks!

flint sage
#

Basically says that no other thread is allowed to access the same object at once

royal raft
#

i just want one thread to do all the generation just not the main one

rugged radish
#

might want to take a look at Unity jobs system

#

that's what I use for parallel mesh generation off the main thread

royal raft
#

ok ill take a look thanks for the suggestion

rugged radish
#

its limitations also pretty much guarantee that you can't write a code that corrupts the data because of parallel writes

#

so no locks are required

royal raft
#

ok thats good then i realy appreciate this since im new to jobs and multithreading

tiny pewter
#

they implement locks but hidden, and no lock in unsafe collection

rugged radish
#

you'll have to use async or unity's specific async surrogate thing, forgot how it's called 😄
to check up on your job, so that main thread can continue

So I currently have an audio system where you can fire off audio events with strings like Wood:HeavyBoot:Footstep and it will go trough the sound banks until it finds a match. If no match is found it removes a decorator and tries again. Im wondering how I can keep this behaviour but eliminate the use of strings. I was thinking of creating a bit set class with a uint[] and set the bits for that, but that leads to way more boilerplate code, cause now I also need a mapping of what index is wood heavyboot and footstep.

tiny pewter
#

so eg A:B:C, if A:B:C not found->search for B:C->still not found->search for C?

#

it looks like trie (prefix tree)?

#

but i dont prefer trie, this tree uses lots of memory for connecting children

livid kraken
#

I haven’t heard of trie, I will have to research it. I was more looking for a solution that would use something like a enum. Obviously a normal enum doesn’t work here

tiny pewter
#

eg if you have following sounds and their decorator (the last character is sound)
1.abcd
2.ace
3.de
4.ad
you will start search from sound then decorator (ie in reverse order)
now you want to play:
bcd-> "whole" sound exists
bd->stop at d, so play d
bce-> stop at ce
xrcd->stop at cd
trie is basically a tree that provides you a faster search function

#

you can turn the sound and decorator to int (btw you will still need string to int hash table to make your coding easier) then construct a trie based on sounds in sound bank

#

or you can have a set of predefined enum, to show you the name instead of an array of int that hardly to understand and waste much time to decode it

tiny pewter
#

there is other way to do that search by maintain a sorted sound bank (same as trie, the format of sound should be: sound->decorator) and use linear scan (or binary search) to find the bound and current position
a bit difficult to tell (this is leetcode question but i forgot what is the name)

scenic forge
#

If there’s a known and reasonable max limit, you can also consider just have a bunch of overloads, each argument is an enum.

livid kraken
#

I dont have a problem with the search time. I just want to avoid the garbage being generated by strings

i just realize that i didnt answer to that question directly, yes use enum for query

SoundBank.SearchSound("name")&&SoundBank.SearchDecorator(enum)&&SoundBand.SearchDecorator(enum)......
sound=soundbank.Result();
SoundBank.Reset();
#

SearchXX will return bool so if soundbank.search return false the first line will stop executes (short circuit evaluation) and you can ask for search result in second line, then reset the pointer (or what ever) in third line

#

You dont need brunch of overloaded methods here but it needs memory

sly grove

You pass a callback into that second parameter

Ive switched my code over to jobs but it seams to still be running everything on the main thread this is what ive got

public void March(int chunkSize, int chunkPosX, int chunkPosZ)
{
CreateMeshData job = new CreateMeshData
{
};

    JobHandle jobHandle = job.Schedule();
    jobHandle.Complete();

    List<Vector3> verticesList = new List<Vector3>();
    foreach (var vertex in job.vertices)
    {
        verticesList.Add(vertex);
    }

    List<int> trianglesList = new List<int>();
    foreach (var triangle in job.triangles)
    {
        trianglesList.Add(triangle);
    }

    List<Vector2> uvsList = new List<Vector2>();
    foreach (var uv in job.uvs)
    {
        uvsList.Add(uv);
    }

    MeshData meshData = new MeshData(verticesList, trianglesList, uvsList);

    job.vertices.Dispose();
    job.triangles.Dispose();
    job.uvs.Dispose();

    chunkGenerator.CreateChunk(new Vector2(chunkPosX, chunkPosZ), meshData);

Which would block the main thread.

sly grove
royal raft
#

oh okay i understand what should i do to fix this i want the main thread to run like normal and no massive fps stop

#

couroutine?

untold moth
#

If you don't care about when the job would complete, you could check if it's complete in update, and only call Complete and use it's results then.

royal raft
#

alright in the game the player wont be able to move very fast so the amout of time it takes is no issue i just dont want the game pausing

#

thank you very much for the help!

sly grove
#

you could also use a coroutine and yield return WaitUntil(() => handle.IsCompleted);

royal raft
#

ill try both and see what works best

sly grove
#

your current code is looping through vertices and triangles etc in the main thread after the job is done which itself may be slow

royal raft
#

ill check it out thanks!

Does anyone know why my code might be freezing when i try to run this async function? I have tried to follow as many async await resources to figure out how to do this properly but my entire editor freezes when i press space. The intended behaviour is for the function to look for player left click and shoot a ray out to see if the player clicked on a Tile on the map, and then return the tile that was clicked.

private void Update()
{
    if(Input.GetKeyDown(KeyCode.Space))
    {
        Debug.Log("start");
        Tile tile = TargetTileAsync().Result;
        Debug.Log(tile.name);
    }
}

public async Task<Tile> TargetTileAsync(TargetType tt = TargetType.All)
{
    targetTile = null;
    playerInputState = InputState.Target;
    targetState = tt;
    while (targetTile == null)
    {
        if (Input.GetMouseButtonDown(0))
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out RaycastHit hit))
            {
                Tile temp = hit.transform.GetComponentInParent<Tile>();
                if (temp != null)
                {
                    targetTile = temp;
                }
            }
        }
        await Task.Yield();
    }
    return targetTile;
}
untold moth
#

So since you're blocking the main thread, the next frame never comes, but it keeps on waiting for it.

stiff widget
#

my understanding was await Task.Yield() would ensure that it only ran once per frame, so this is actually blocking me from reaching the return?

#

in that case, is there a need to ensure that the loop only runs once a frame, and if so is there a better way to do that?

untold moth
stiff widget
#

yea i dont know why i missed that, so i could just return inside of the loop and it would work right?

untold moth
#

Mmm... I'm not sure what you're trying to do there. Returning in the loop would just quit the async function.

stiff widget
#

the purpose of the async function is to wait for the player to click on a valid spot on the map

#

and when they do that i want to return where they clicked

untold moth
#

That feels like a vary bad use case for async.
Why not just check what the player clicks in update?

stiff widget
#

I needed to call this function from a script that needed multiple different targets and i wasnt able to figure out how i would return that information from update

untold moth
#

Well, you could raise an event when a player clicks a tile. In your script that needs that info, subscribe to that event when you want to know that and each time the event is triggered, add a tile to a list. When you have enough info, unsubscribe from it.
