Normally for terrain you'd want to have a cpu side representation first, or is it for some sort of vfx?

rugged radish
#

I want smoothed interpolation between centroids of the voronoi (driven by symmetric curve functions)
cpu side has the graph and other related data, and compute shader must turn it into a height map that will be later read back by cpu

I use compute shaders because cpu is too slow to generate it at runtime

#

particularly, this stage is the first in the pipeline, intended to block in major areas of foundation

sage radish
rugged radish
#

also, I still have no good algorithm

#

the ones I found are much heavier than simple benchmarks I used

#

those are from other fields, that aim towards precision

plucky trellis
#

are you sure you want to store this as a heightmap and not just generate a mesh outright?

rugged radish
#

I couldn't find anything directly compsci related

#

mesh is not a problem, issue is to find a fast algo that can interpolate a surface based on nodes of the graph

sage radish
rugged radish
#

so first pass would be linear, and second pass will blur, producing an interpolation, but I think it will have a very similar look

#

I will give it a try tho, thanks

#

just to see how it looks

sage radish
#

But I agree that generating a mesh instead of a heightmap seems ideal, if you want sharp edges.

rugged radish
#

oh, actually I want the opposite for this stage, it must be smooth

#

detailing stages are the ones that will have sharper transitions

sage radish
#

Or do you want to smooth it all the way so it looks like rounded hills?

rugged radish
#

ideally I'd like the 2nd picture, so even more smoothed, but w/o any visible artifacts (like the seams)

it should produce more like plateaus, flat top with smooth transitions

#

the example is just the extreme to easily see how good an algo can smooth out transitions, in practice cells will be in large groups of the same height, that will need smooth transitions from one group to another

#

and multiple groups of different height can neighbor eachother

soft marlin
#

my best guess would be that creating gameobjects in [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.**SubsystemRegistration**)] will fail because there is no scene loaded to create a gameobject in. (but in the editor you already have a scene). try and change it to AfterSceneLoad

#

or maybe **BeforeSceneLoad ** would be better actually

Weird question, im currently in the making of a pathfinding system, and i have various "NavigationVolumes", with different sizes (length, width, height). Im currently trying to make a method for flattening int3 index into a regular int index. The Problem is that each Volume has different Sizes, so its not known if the x, y or z axis is the highest length, any idea how i can make a modular array flattening method?

Hey guys

#

How do I go about rendering an object without a gameobject?

#

This is what I use right now, but as you can see the object only has one material

RenderParams rp = new RenderParams(round.mat);
Graphics.RenderMesh(rp, round.mesh, 0, Matrix4x4.TRS(RoundPoints[0].position, RoundPoints[0].rotation, Vector3.one * 5));

delicate mural
#

The round you see in the mag is missing the head, and primer in the back.

#

These are all one object but the regular rounds have multiple materials

sly grove
#

Right that means a different submesh

delicate mural
#

Different materials are submeshes?

sly grove
#

RenderMesh has a submesh parameter

#

Yes each material is applied to a different submesh

delicate mural
#

Didn't know

sly grove
#

First material goes to submesh 0 and so on

#

So you would call it again with submesh 1 and the second material

#

And so on for however many submeshes and materials you have

delicate mural
#

Well that's not right

image.png
# 
    void RenderAmmo() {
        CartridgeData[] rounds = ammo.ToArray();
        for (int i = 0; i < rounds.Length; i++) {
            CartridgeData round = rounds[i];
            for (int ii = 0; ii < round.mesh.subMeshCount; ii++) {
                Graphics.RenderMesh(new(round.mat), round.mesh, ii, Matrix4x4.TRS(RoundPoints[i].position, RoundPoints[i].rotation, Vector3.one * 5));
            }
        }
    }```
#

Right now I'm passing in the material through cartridge data

#

I always felt that this is a realy bad way of doing it

#

@sly grove Is there any way to make this more efficient? I don't want to have to serialize an array of materials for each bullet type

sage radish

Hmm, okay

#

I'll bake it in blender

It looks so ass when I import it into unity, maybe this will fix that too

Does anyone have experience with playables? I have an AnimationClip with a curve of "LimitRotation" and when I use an AnimationClipPlayable it doesn't update the Animator with that curve. I've seen some stuff online about animator.BindStreamProperty but can't figure out how to get that working.

dusty wigeon
# slender rivet Does anyone have experience with playables? I have an AnimationClip with a curve...

I did rewrite a part of the Animator for prototype and I did not need to bind any stream property manually. Unless there is more to it than what you are saying, simply animating the property from an Animation Clip should work.

Also, is there any reason why you would not use the Rigging package for ? (Unless you are using it and I'm overstepping what I assume) You would be able to read the curve and modified the resulting animation.

I was under the impression that the animation rigging package was for IK. The main think I'm trying to do is keep a mechanim system for most of the character control, but then have a playable graph with a mixer that goes between the controller and a one-off animation clip. Think emotes from Dark Souls or other online games. There can be hundreds, so I don't want a state for all of them. States in the main state controller use a parameter called "LimitRotation" that will stop the character from rotating towards the move direction when certain actions are taken (sword swing, throw grenade, etc). The animation clips used in the state controller have that LimitRotation curve on them, but I also want the emotes to use that curve. However, just adding it does't update the float. so if I'm doing an emote and called Animator.GetFloat("LimitRotation") it comes back as 0. I heard I can use the BindStreamProperty to sync the curves between the Animator controller and AnimationClipPlayable, but so far have had no luck

Why are you not using a standard animation key in a clip ?

Why are you not using Animator Controller Override to change the animation in the Animator ?

Why cant you use a parameter in your State Controller and control from there ? (I imagine that you would have an Attack State, a Taunt State, etc. to control the behavior of the character. Simply limit the movement when the character is in that state instead of when he is in an animation)

Something like:


public void AttackState : State 
{
  public override bool AlignWithMovement => false;
}

public void State 
{
  public void Update()
  {
    if(AlignWithMovement)
      character.LookTowards(character.LastMovement);
  }
}

What do you mean by "standard animation key in a clip"? This is a curve on the clip, and if the clip is on a state in the animator controller then it works, but when using playables it doesn't update the animator float.

I thought the playables API was the new way of doing things and animator controller override was the old way since it's limited. I can't programmatically create several animation clip sequences for example. Everything has to be there exactly right at editor time, not runtime.

LimitRotation is a parameter on the controller. If the clip was there it would work. I wouldn't even mind needing to read LimitRotation from two places if I have to check it from the Animator and also check if there's an AnimationClipPlayable playing a clip that also has that curve.

It's not as simple as "when you're in the attack state, look at the camera".

There is so many other option before trying to play with Playable API. The playable API is not the "new way", it is simply a way.

You can simply have a MonoBehavior on your gameobject that has a Monobehavior with a variable LimitRotation.
You can use animation layer with the sync attribute. https://docs.unity3d.com/Manual/AnimationLayers.html => Animation Layer syncing
You can read the Animator state. https://docs.unity3d.com/ScriptReference/Animator.GetCurrentAnimatorStateInfo.html
You can modify an animation clip. https://docs.unity3d.com/ScriptReference/AnimationUtility.html
You can use the Rigging Package to add post animation job. https://docs.unity3d.com/Packages/com.unity.animation.rigging@1.0/manual/index.html
You can use AnimatorController Override (And yes, you can do it at runtime) https://docs.unity3d.com/ScriptReference/AnimatorOverrideController.html

There is so many option, using the Playable API is not one that would recommand from what I see.

Most of these aren't what I'm looking for. I already have a controller with a bunch of layers and states. I'm trying to play a clip without using the states. I know I can use AnimatorController Override at runtime, but I don't think you understood what I meant by that. I meant I can't adjust transitions at runtime, so if I would need permutations of every kind of transition out of the overridden state including ones where they trigger a sequence of other animations, or have a short transition out of the clip, or a long transition, or a transition halfway through. I would rather do this with script.

What does the Rigging Package have to do with this? I already tried setting up an AnimationScriptPlayable IAnimationJob and grabbing the value during the ProcessAnimation function using the BindStreamProperty method I talked about before, but couldn't get it to work either. I'm not sure if "post animation job" is different than the animationjob I already tried.

I feel like I'm looking for something simple. I have an animation clip with a custom curve on it. I want to evaluate that curve when the clip is being played by an AnimationClipPlayable. Is this impossible? The AnimationClip only has a SetCurve function, not a GetCurve. I've seen some editor utilities to grab stuff, but I can't use that because this has to be runtime and you can't build editor scripts.

Here's a basic version of what I'm trying. This works where I can call Play(animationClip) and it overrides the Mecanim Controller with the Clip I want. I just also want to either update the Animator's float parameters with the clip curves like mecanim does by default, or have some other mechanism to evaluate the clip's curves. I know there's other ways to get this to work, but I just want this to because I'm trying to learn more about the Playables API and I'm losing my mind because everything feels either half finished or completely undocumented and every time I search the forums for help all I find is answers by one guy who keeps telling everyone to buy his asset instead of using the API.

Weapon Animation ? Taunt Animation ?

languid remnant

Does anyone have a method to flatten a int3 index into a int index?

I have a dynamic grid, where the user can define the height,, width, depth

dusty wigeon
#

Or a bit of thinkering

slender rivet
# dusty wigeon What exactly, concretely is the objective.

Well, anything really. Emotes right now, but I was thinking if I was making a game like The Sims where a house is full of hundreds of different items that all use their own unique interact animations, you could have the objects themselves provide the animationclip used to interact with them. Or maybe a hack and slash where the weapons themselves provide the different attack combo animations. I know Override Controllers exist, but that wouldn't work with attack combos where complexity can vary wildly there. I just want to figure out how to do this with the playables api.

dusty wigeon
# slender rivet Well, anything really. Emotes right now, but I was thinking if I was making a ga...

From an architecture stand point, it is really a bad idea to have the items define the animation. The decision of what animation to play is a conjoint decision between the item and the animation, the item could "suggest" an animation but ultimately, the decision should be done by the actor.

In situation like the Sims, having every animation defined in the Animator could effectively become an issue, however the usage of Animator Override Controller would suffice. Before playing the animation "Emote", replace it with the appropriate animation.

In situation like an hack n slash, you should definitely be able to define all the different archetype weapon animation inside the animator. I see no issue with simply using the animator how it should be used.

If you really insist in using Animation by code, you can use the Legacy Animation, use the Animator.Play function or you can buy Animancer which is a well reputed asset that does the work you are trying to do there. https://assetstore.unity.com/packages/tools/animation/animancer-pro-116514

The last I would suggest to do is to reimplement the Animator yourself or to extend it with Playable. It is a considerable task, there is not a lot of documentation and you will most likely finish with something worst than using the Animator byitself.

# dusty wigeon From an architecture stand point, it is really a bad idea to have the items defi...

I disagree about it being bad. Weapons can have wildly different combos. A mixture between light and heavy attacks, various transitions between them, if there's early exits for some attacks if the player is also moving vs standing still, etc. Every weapon can be wildly different. Also, lol, Animancer is built on Playables. If it does what I'm trying to do, then how did it do it? I'm not looking for other architectural solutions or other options. I want this to work with Playables. I don't want to use the legacy system, override controllers, or an asset. I just want to figure this system out for myself. If you're not sure, then that's okay too. I don't want another solution tho. Also, even if I remade the animator, I still have the problem that I can't read the clip curve values which is what I'm trying to solve in the first place!

dusty wigeon
# slender rivet I disagree about it being bad. Weapons can have wildly different combos. A mixtu...

My point is that the Playable API is not something that is easy to work with (Having rewrite a part of the Animator function for a prototype), hence other solution should be favorize (The issue is not with the solution base on Playable, but bulding a solution that use Playable). From my experience (50 weapon archetypes for an Action Combat title with combo), the Animator Override Controller does the job.

I am sorry that I cannot help you directly with your issue. Usually, to "read" a value from an Animation clip you simply have to the key in the Animation Clip. By example,

public class MyClass : MonoBehavior {
  public float MyValue;
}

Then have a key in the animation clip that reference MyValue. The same way you would edit a position or a rotation.

However I evidentally get this message:

You are trying to create a MonoBehaviour using the 'new' keyword.  This is not allowed.  MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all

Hello.
How might I go about making a loose ammo belt with physics?
I mean obviously you could string a bunch of rigidbodies with joints, but this is simply unfeasable performance wise. There could be as many as 200 rounds in a loose belt.

#

I was wondering if anybody could think of a much, much more performant solution

#

What I'm referring to, if anyone doesnt get it

image.png
long ivy
#

find a way to cheat. If you were carrying the above thing around, probably only the hanging bullets would move much so add a couple joints to let them sway around to sell the effect and the rest are stationary

#

otherwise you might try something based on a rope solution

delicate mural
#

That would be perfect for my game... if it was performant

delicate mural
#

Hell, I could even make a system that smothes out the curve, so it would look smooth while using less rigidbodies

#

What is the performance impact of 40 rigidbodies connected by joints?

long ivy
#

is physically-simulated bullet-belt jiggling a crucial gameplay element? The idea I suggested would probably use like, 5 or 6 joints total. Just enough for some sway in a skinned mesh that was modeled around the gun. Normally the cpu time you'd spend on this would be better used elsewhere

delicate mural
#

VR

#

No game I know of has physical belt links. Even hardcore gun simulators like H3VR shy away from them

long ivy
#

you might want to just slap it together exactly as you described to see how well it works. My gut says using so many joints not only won't be performant, but the physics will bug out in some way and totally destroy the effect you're going for

delicate mural
long ivy
#

I was thinking more along the lines of they bug into the gun and then physics depenetration shoots them into space

delicate mural
#

Oh well the closest links will ignore cols with the gun

#

The only practical usage of belt links is putting em over your shoulder, they could be made to sleep when in that state

#

Well, I know People Playground's people consist of 14 limbs all connected by links and rigidbodies

#

There is barely any performance impact from 3 people in the scene

#

I guess I will just have to see for myself

heya, would anyone be able to point me in the right direction with an issue i'm having involving rigidbody movement? nothing i've been able to find online has helped so far
it might be a little hard to see here, but you can ignore the clipping into the ground and etc.
the issue is that while I'm moving (and while the rigidbody/flamethrower is meant to be moved to my new position), it's rotating and therefore won't actually move for some reason

#

basically, it seems like it will only ever rotate or move, so it won't snap to me until i stop moving my mouse

# 
if (pinToCaster) {
                    Vector2 direction = MathExtensions.VectorFromAngle(moveAngle) * (1 + pinAngleOffset);
                    if (lifetime + moveDelay <= Time.time) {
                        rb.Move(transform.parent.position + new Vector3(direction.x, 0, direction.y), GetIconRotation());
                    }
                }

the flamethrower is the child of the player and this is the code setting it to the new position

#

a few q&as suggested calling MovePosition and MoveRotation separately was doing it, but no luck. a few others said it was using transform.position instead of rb.position, but same deal

#

rotation and position values are correct, i know that for sure, it's just like it's incapable of moving and rotating simultaneously

#

or, i guess from looking at the video, it's more like it will only ever snap to me once i stop moving altogether, not when i stop rotating it

You could do a Delaunay triangulation of the point set, then pick a triangle in the middle, then incrementally pick random adjacent triangles, repeat a couple of times. The outside edge of the so selected triangles should be continuous and concave

Hi! I have a very specific problem and if anybody will manage to solve it, I'll literally swing my ballz ;D

RAYCAST vaultHit.point is where the raycast hits. It's a vector position.
The entire box is box collider.
I have another vector position (raycastOrigin1) to which I have to move the vaultHit.point but I need to know how far is that distance from vaultHit.point to raycastOrigin1. It needs to be calculated somehow. I'm struggling with this for so long and I can't find a solution. This is really important.
Note that you can't just use bounds.size x y or z because the collider can be rotated or the size/scale can be different so then it's not working correctly.

I think it's a realy complicated advanced math problem. Im not good at math so...

If you know the plane that goes through the raycastOrigin and the center, you can project your Hotpoint to the plane to get the point.

the entire rectangle

#

and the vaultHit.point is on the side wall of it

untold moth
#

Yeah, I don't understand the question. You said that you want to move the hitpoint to the raycast origin..?

lapis gale
#

yeah. raycastOrigin is local Vector

#

it's being calculated based on that

untold moth
#

If you know the target destination(raycast origin), just use it, no?

#

I don't understand what the problem is?

lapis gale
#

the raycastOrigin is where the vaultHit.point should be moved

#

but it will be different on every box collider because of it's scale

untold moth
#

Since it's the raycast origin I assume that you already know it?

lapis gale
#

NO im telling you Im not. Im trying to calculate it

#

it's where it's supposed to be

untold moth
#

Okay, then my initial reply was correct.

#

Because you're talking about raycasting and hit points, so I assumed that raycast origin is the origin of your raycast.

lapis gale
#

yeah my bad. I named it like that.

untold moth
#

Maybe name it "target point" or "unknown point" instead of raycast origin.

lapis gale
#

initial raycast is vaultHit.point

Hey fellow nerds,
I'm working on an app for a client/friend. I'm trying to get images that are pulled from firebase to display in-line with text. I'm told by gpt that converting it into a sprite would be the best way to do it. I'm successfully converting to a sprite but stuck on getting it to show up.

description.text = (string)selectedTask["Description"];
        if ((string)selectedTask["TaskImageRef"] != "")
        {
            Texture2D imageTexture = await fBRequests.GetImage(
                (string)selectedTask["TaskImageRef"]
            );
            spriteAsset = Sprite.Create(
                imageTexture,
                new Rect(0, 0, imageTexture.width, imageTexture.height),
                new Vector2(0.5f, 0.5f)
            );
            spriteAsset.name = "Task Image";
            description.text += $"\n<sprite=Task Image>";
        }

yes, correct

static flint

I want it to be called by the other thread and run in the main thread

novel plinth
#

you'd need to dispatch it so it will run on mainthread

static flint
#

could I get an example or resource

novel plinth
#

thread dispatching is just some fancy terms 😃

#

here's a poor mans one :

void MyThread()
{
   Thread nthread = new Thread(()=>
   {
      myqueue.Enqueue(()=> Debug.Log("From thread YAY!"));
   });

   nthread.Start();

   //OR just use TaskFactory tagged with LongRunning so it will guarantee create a new thread
}

static ConcurrentQueue<Action> myqueue;

void Update()
{
  while(myqueue.TryDequeue(out var func))
  {
      func.Invoke();
  }   
}
#

based on how you asked this matter, just don't do it. It's clear you've no clue of how to do this let alone doing it properly.

#

if you're expecting it will make your game runs faster, fat chance it might not

#

also use JobsSystem instead of rolling your own

soft marlin
# static flint could I get an example or resource

what Slim said. also depending on use case, using async/await with Unitask library might serve you needs better, as there are handy utility functions for this kind of stuff.

eg.

async UniTask SomeExpensiveFuntion() {
   
    await UniTask.SwitchToThreadPool();   // Multithreading, run on ThreadPool under this code
    // slow work.

    
    await UniTask.SwitchToMainThread();   // return to MainThread
    // call unity functions

    await UniTask.SwitchToThreadPool();   // Multithreading, run on ThreadPool under this code
    // do more slow work.
}
novel plinth
#

UniTask.SwitchToMainThread is just Task.ThreadPool.QueueUserWorkItem which basically the same as Task.Run

Hey guys kind of a weird question but I want to add modding support to my game. I tried using preinstalled Bepinex but its kinda weird and I want more in-game control over it. I have previously figured out runtime execution of a raw c# file, but I kinda want the hooking stuff from Bepinex, specifically HookGen from Monomod that kinda makes all the existing functions into events you can latch onto. Is there some way to integrate that or make a similar thing myself? Obviously without redoing a lot of the game.

soft marlin
# sleek lantern Hey guys kind of a weird question but I want to add modding support to my game. ...

I've never used bepinex so can't say much about that. first off, I want to target il2cpp so bepinex is a no go. but most importantly the multiplayer/netcode stack I have calls for good control over execution of scripts (and 'mod scripts'), so that mods are multiplayer compatible out of the box. To that end I've had a good time / experience implementing Lua w/ moonsharp.org as the scripting environment. But it's not a catch all, if you need to be able to mod 3dmodels etc, then combining moonsharp with unity addressables is probably the way to go. you're also probably going to have to sprinkle on some JSON/XML as well to hold metadata.

now, for a lot of this I'd say that you don't need to redo a lot of the game. but that depends a lot on the scope of modding capability you need and architecture of the game. I'd say that modding isn't a drop-in last minute thing, as it is a lot of work to get these systems working and talking with eachother, but maybe that's what bepinex offers.

how can I make an observable property in unity, that aside from working with UI Toolkit also works with my other scripts? What I mean is for example a Sphere : MonoBehavior class which has float radius property, which:

  • can be displayed in inspector
  • can be controlled by other scripts (for example animator or something)
  • can be controlled with gizmo
  • I can watch for changes, so for example when radius updates, I can watch those changes and update some shader uniform
#

I was previously used to the old, non-UI toolkit way of storing new value + old value and comparing if(old != new) doThing(), but I see now that UI Toolkit offers data bindings and whatnot, so maybe there is a better way of doing that nowadays?

untold moth
#

Just write a poco wrapper for your value with events and what not.

hardy jacinth
#

But what to wrap to marry events, serialization and inspector though? I am a bit lost, can you show an example?

I am trying to make a tone generator and have tried about 8 different ways, but I get issues no matter what I do. This one has a click/pop sound in between each cycle. I have tried making the cycles longer and fading, but that makes it far worse. I have tried doing 3 at a time and cross fading, but still have popping sounds. Code link since its kinda long, I have buttons setup for changing frequencies: : https://pastecode.io/s/uxj1mw5r

Tone Gen (uxj1mw5r) - PasteCode.io

Has clicking problem in between each cycle.

bleak citrus
#

a "cycle" being a single iteration of that while loop?

#

You reset the angle to 0 every time that happens.

#

This is going to cause a discontinuity

#

You need to remember the angle you stopped and resume from there.

bleak citrus
steady stirrup
bleak citrus
#

You need continuity in both the amplitude and in the change in amplitude (so, a continuous first differential: it shouldn't suddenly change direction)

#

When I'm editing an audio clip to loop seamlessly, I trim off the ends so that it ends and starts with a rising amplitude that's just crossing over zero

#

an example of your problem

image.png
gilded ginkgo
#

Thanks guys! Makes sense, I got it much smoother now, just a little stutter, maybe adding a buffer?

#

ehh, buffer made it worse, maybe it will be fine

gilded ginkgo
#

uhg, nm, sounds good on the PC, but crackles on Android/Quest3

bleak citrus
#

Your other problem is that yield return new WaitForSeconds is not precise enough

#

It's going to resume on the first frame after that much time passes

#

Assuming you're allowed to modify the data in an audio clip as it's playing (i haven't done this before), you should consider using it like a ring buffer

#

you write data to the buffer over and over, jumping back to the start every time you run off the end

#

the audio source just loops over it

regal lava
#

serializeproperties would update as you change them tho

#

I dont do much editor scripting but they would always update when I was editing my level editor

dapper cave
#

They do, so that part seems to work.

#

It's the serialization portion I've never worked with, trying to not have it called in certain conditions

#

for example when I drop a prefab in the scene, I'd like the serialized field to not be reset to null

#

it seems weird that OnAfterDeserialize and OnAfterDeserialize get called each frame even if i don

#

t touch the inspector, but that's ok for now, the prefab losing its value is more important

#

the documentation on deserialization is good

#

problem fixed.

#

wow that serialization is something

#

here's what happened: when you drag a prefab, when it reaches the scene view, the prefab gets serialized then deserialized then serialized again each frame you move the instance.

midnight violet

# midnight violet dont ask to ask... how would you answer your own question

mb, anywho, i have a problem with vector3.MoveTowards. so i have a save system in my game, and when i go back in the save, i got enemies that are saved from the same position that the game saved them on.. if that made sense. problem is, it looks like the problem is always the same:

there are 6 points in which the enemies follow. when they hit point 1, they go to point 2, and so on. when i reload a saved game, the closer the enemies are to their next point, the slower they are. then the second they touch that next point, its like their movement is back to normal.

ive checked all the settings and they are perfectly fine, the movement speed is normal, position is normal, its just that its like the closer the enemy was to their next point, they got way slower until they hit that point. i think its because of vector3.movetowards

i have a video if you need it

#

i just use transform.position = Vector3.MoveTowards(transform.position, nextPoint.position, moveSpeed * Time.deltaTime); btw

midnight violet

Assuming that moveSpeed isn't changing, that line of code is fine

one thing I notice, your aes.key needs to be exactly 32 bytes long

let me share my code

        static byte[] DefaultEncrypt(KeyData keyData, byte[] bytes)
        {
            //Common.ErrMsg($"Encrypt {keyData} {bytes.Length}", true);
            using (MemoryStream ms = new MemoryStream())

                using (Aes aes = Aes.Create())
                {
                    aes.Key = keyData.GetKeyBytes();

                    using (CryptoStream cryptoStream = new CryptoStream(ms,    aes.CreateEncryptor(), CryptoStreamMode.Write))

                }
                return ms.ToArray();

        static byte[] DefaultDecrypt(KeyData keyData, byte[] bytes)

            using (MemoryStream ms = new MemoryStream())
            {
                ms.Write(bytes, 0, bytes.Length);
                ms.Position = 0;

                using (Aes aes = Aes.Create())
                {
                    using (CryptoStream cryptoStream = new CryptoStream(ms, aes.CreateDecryptor(keyData.GetKeyBytes(), keyData.GetIVBytes()), CryptoStreamMode.Read))
                    {
                        using (MemoryStream ms1 = new MemoryStream())
                        {
                            byte[] buffer = new byte[4096];
                            int numRead;
                            while ((numRead = cryptoStream.Read(buffer, 0, buffer.Length)) != 0)
                            {
                                ms1.Write(buffer, 0, numRead);
                            }
                            return ms1.ToArray();
                        }
                    }
                }
            }
        }

in this case KeyData contains byte[] for Key and IV

cursive perch
#

is there any specific reason you set the length of the buffer to 4096?

upbeat path
#

nope, just personal preference

cursive perch
#

okay, I tried to integrate some of your code into mine, hows it look?

image.png
#

changed var decryptedData = ms.toString to var decryptedData = Encoding.ASCII.GetString(ms.ToArray());

upbeat path
#

I think you need to set decryptionStream.position back to 0 after filling it

cursive perch
#

okay

#

the error is inconsistent so i will try to break it again but so far so good

upbeat path
#

Also I think you should only be passing the Key and IV into the Decryptor not into the create

cursive perch
#

commented that out

#

how do i go about converting my class into a byte array for the encrypt?

upbeat path
#

Encoding.Ascii.GetBytes

#

if your using a JSON string. Although I prefer using UTF8

cursive perch
#

wont let me convert it

#

hold on

upbeat path
#

but you had that in your original code

var json = JsonUtility.ToJson(data);
    await cryptoStream.WriteAsync(Encoding.ASCII.GetBytes(json), 0, json.Length);
cursive perch
#

yes sorry, had the order mixed up

#

was converting after

upbeat path
#

I presume you have tested this without the encryption

cursive perch
#

yes, worked great

upbeat path
#

cool, so you know the data is good

cursive perch
#

yes, ive got your code working now so i will see if I can manage to break it again, but hopefully it works

upbeat path
#

excellent

cursive perch
#

broke it

#

getting the same exact error as before

#

probably something to do with my other methods then

upbeat path
#

how are you creating your IV ?

cursive perch
#

i just have it as a private variable

upbeat path
#

Ah, I let aes create it

            byte[] bytes = Encoding.UTF8.GetBytes(key);
            this.key = new byte[32];
            if (bytes.Length < 32)
            {
                Array.Copy(bytes, this.key, bytes.Length);
            } 
            else
            {
                Array.Copy(bytes, this.key, 32);
            }
            
            using (Aes aes = Aes.Create()) { 
                aes.Key = this.key;
                IV = aes.IV;
            }
cursive perch
#

so it's a random key and iv everytime? would that work for a game where you can download other player's levels?

upbeat path
#

the key is not random, that comes from a predefined string and aes generates the IV based on that key

cursive perch
#

ah i see, my first time working with encryption. so i could just run this in the encrypt decrypt methods and I would be okay?

upbeat path
#

yep

#

that code is part of my KeyData class

cursive perch
#

had no luck with letting aes create it

#

anything wrong with: private static readonly string Key = "xXpHrsMPSBqHgF8zDvIFjkRGUgAI3OAh"; private static readonly string IV = "22UTdQohm3SczcwpIwHfmL==";

upbeat path
#

I can't speak to the IV but the Key looks ok but why are you using FromBase64 to change it to a byte[] you only really need Ascii.GetBytes

cursive perch
#

gives me a IV / block size error when i replace it

upbeat path
#

the first thing I said to you was the key size must be 32 bytes.

            string key = "xXpHrsMPSBqHgF8zDvIFjkRGUgAI3OAh";
            byte[] bytes = Convert.FromBase64String(key);

produces a byte[] of 24 bytes in length

scenic forge
#

IV should never be static, it should be generated randomly for every message and attached to the message, otherwise it's trivial to break your encryption.

#

But taking a step back, what are you using this encryption for? If you are using it to do things like protecting game saves and what not, just so you know that it's practically useless. Anything in client should be considered compromised, and your key is in your client.

upbeat path
#

I think it best to just get his code actually working first and then consider the implementation details, we don't even know if this is running on the client

scenic forge
#

Both can happen at the same time 😄

#

But I personally like to address XY problem as early as possible so it's not wasted effort to get an infeasible solution working just to be discarded.

upbeat path
#

even if it is discarded it's a good learning experience

Is there any way to calculate how long did a burst job took to finish without having to start a watch before scheduling and stopping after complete?

the first one is that there might be some delay since scheduling until the job actually starts, the second is that if I don't want a delay I need to call complete inmediatly after schedulling and that removes my use case

hey devs!! I need some suggestions when it comes to managing delegates... currently for one of my projects, I have multiple managers in place and am using delegates extensively to manage the communication between them... I have a static Delegate Manager class to handle all these delegates and anyone of the managers can subscribe and unsubscribe to them depending on the situation... this thing works like a charm but somewhere I have realised that this is definitely not the best way of doing it due to the issues that arises from singleton and also might increase the dependency on the managers... I am trying to stick to the SOLID pattern and hence I went on into doing it this way... How do you guys handle them

sly grove
#

Anyway the risk of static delegates is failing to unsubscribe which leads to bugs and memory leaks.

#

which is maybe fine, assuming you are diligent about finding and mitigating such issues.

Does unity or any other ready made solution have a functionality to shorten this workflow:

    [RequireComponent(typeof(MeshCollider))]
    public class Foo : MonoBehaviour
    {
        MeshCollider _meshCollider;

        void Awake()
        {
            _meshCollider = GetComponent<MeshCollider>();
        }
    }

Where instead of adding an attribute to the class, I'd just assign [Require] attribute to a serialized field and it would add it if it doesn't exist in the object and assign it, this is the result I am hoping to get:

    public class Foo : MonoBehaviour
    {
        [Required] MeshCollider _meshCollider;
    }

Preferably RequiredAttribute would inherit from SerializeField making it easy.
Note: the field restriction would probably be fields inheriting from Component

#

If not I'll create one myself because I can't think of a downside...

sly grove
stuck plinth
#

nothing built in afaik, there's some overhead there with reflection and processing attributes at runtime that's probably better left up to users

misty walrus
sly grove
#

Yes with SerializeReference

stuck plinth
#

i think some of the unity-aware DI frameworks like zenject can do something like this? although i've never used them that way myself

misty walrus
stuck plinth
#

well, your example has it in Awake

sly grove
#

but yeah it's unclear when the assignement would happen

misty walrus
#

I'd just create a custom attribute drawer, and assign it during its gui generation phase.

# 
    public class Foo: MonoBehaviour
    {
        [SerializeField] ITest _test;
    }

    public interface ITest
    {
        
    }

Am I misunderstanding what you meant by serializing interfaces?

stuck plinth
#

drawers are fine if you definitely only create these by hand in inspector, watch out for issues if you ever want to create instances programatically though! since the drawer gui code won't run

how can we handle negativ worldpos correctly to get the right local ones

public void OnEditBlock(int3 globalBlockCoords, BlockNative block)
{
    if (!dataGenerated) return;

    int index = localBlockCoords.x + localBlockCoords.y * width + localBlockCoords.z * width * height;
    chunkData[index] = block.BlockID;

    // Assuming chunkManager is an instance of ChunkManager
    // Generate mesh for the chunk containing the modified block
    chunkManager.GenerateMesh(Generate(false));
}

#

so you want local values to not go into negative positions so make sure your coordinates just extend into the positive plane of values (pivot would usually be a corner defined as 0,0,0)

#

so by doing transforming a point from world space to local you'd always get a positive value

#

probably ways to do it with a centered pivot, but I've went with the easiest solution

Can under some circumstance in Time.frameCount become negative? I ask because the documentation says:

Internally, Unity uses a 64 bit integer which it downcasts to 32 bits when this is called, and discards the most significant (i.e. top) 32 bits.
Not exactly sure what does that means,

I'm trying to read a dll and pdb file, using Cecil. Fairly working if I don't use the pdb file. This DLL has been compiled by Unity. From what i understand, Unity generates portable format PDB files.
~~Cecil is failing while reading the PDB file while checking the magic number 1112167234U in latest its in hexadecimal but still the same 0x424a5342 inside the PDB file. Mainly at ImageReader.ReadMetadata : ~~

private void ReadMetadata()
    {
      this.MoveTo(this.metadata);
      if (this.ReadUInt32() != 1112167234U)
        throw new BadImageFormatException();```

~~So, my PDB file does seem to be correct, but Cecil unable to open. Ideas?e~~

I want to create a method that can take any variable as ref, then replace the value of this variable to the value based on what button I pressed. My code looks more or less like this:

void DrawButton<T>(ref T item) where T : Object
{
  DropdownField dropdown = new DropdownField();
  dropdown.RegisterCallback<ChangeEvent<string>>((registeredEvent) =>
  {
    item = assetsByName [registeredEvent.newValue];
  }
}

The problem is that the compiler won't let me use ref values inside a delegate. I think I need some workaround.

scenic forge
#

That's simply not allowed

#

item could be a variable on stack, which might be gone by the time the lambda is called.

#

You can either have a wrapper that contains the value, or you can simply make DrawButton take a callback.

Hey there, I am trying to learn how to make procedural generated maps, but I want my maps to be already determined before I actually generate them, For example a game like Helldivers (First one), the maps are procedurally generated but it shows the mini map before dropping to the game, how does it do that? The only knowledge about procedural generation I have is creation of maps using perlin noise only

this is the example

The "Basic" thing I am trying to do is get an object to move around the same way your hand is... Kinda like one of those VR hand things (Except i dont own one)

I have tried:
Joycon: Accelerometer seems to track rotational speed instead of movement speed in space?
Ps4 Controller: Gyro gives good data, accelerometer gives garbage data.

Any tips/ideas? Or should I hanker down and find a cheap VR hand controller?

does anyone have experience with the vfx graph? I'm seeing something shady...

When I first activate an effect, the system starts playing. This works.
Now, when at a specific frame after activation I activate a second effect, the first effect will stop playing. (HasAnySystemAwake becomes false etc)

This is impossible to reproduce when playing only a single effect, but quite easy to reproduce when playing two of them within 1 or 2 frames of each other. This is happening for effects with the same graph, shortly after activating one of them (when none of them were active before)

This might be shader related but i'll ask here: I'm tryna make a strategy game and i have two players. Each player starts with territory, and needs to capture the other player's territory. Currently, the world map is just an image, and I have another image with the territories of each player (red and blue). What would be the best way to render the territory? I intend to have free moving units that actually capture the territory. I could split it up into a bunch of smaller segments manually, or I could use a grid based thing, but I feel like that isn't the best way. World map is pictured (its an 8000 by 4000 or something image). I have a texture of just the land too with nothing on it.

image.png
#

I feel a massive dictionary of every land point (excluding neutral points which is a vast majority of the map) might not be super performant but I dunno

#

my main issue tho is how to render it

sly grove
#

that way you can handle things like selecting/mousing over each

#

that will make it easier to handle the mouse events as well

dusty wigeon
sleek lantern
#

eh I don't really think i need each country to be individual image since I'm planning on focussing more in individual units than whole countries

#

and each faction is basically a bunch of countries anyway

#

actually its gonna be turn based so I don't think I'll have to deal with mouse input so thats nice

#

I'm currently planning on using a low res texture to store the territory

#

like blue = player 1 and red = player 2 and it just gets put above the background to show it

#

dunno if it will be super performant cuz I have heard bad things about Texture2D.Apply()

Hi, I am making a zuma like game but i just cant wrap my head around this. I have a DoTween path that only one object follows, it is currently speed based. When I destroy balls the balls behind the destroyed should stop and the front balls should go back to reconnect. But I am not sure if This is the right way to do it, with a timer. Anybody have any idea on how I should approach this?

Here is the code https://gdl.space/ujuyekelax.cpp

karmic solar
#

you make it run, and having a few 2D textures applied each "turn" or whatever on a series of flat images is NOTHING for your CPU

#

the idea of using a dictionary or at least a map for your... map seems like a nice idea I think, but as other people said, you probably need to break that map image into smaller managable chunks

Does anyone have a good estimation on the upper bound of geometry generated from marching cubes? Previously I was doing
#cubes * (5 triangles per cube) * (vertex_stride * 3)

However, if you account for duplicate vertices, you can reduce it to
(#cubes + 1) * (3 vertexes per cube) * vertex_stride

Which reduces the amount of vertices by a factor of ~5. However, I do believe it's impossible for literately every cube edge to contain a vertex--is it possible to reduce it further with a better estimation? I want to save on buffer space

Hi everyone !
I have a question about responsability : I'm struggling to define which script should be responsible for what.

I have a plain, serializable Unit class that, that is pure data. This stores the Id, the Health, Magic Points and whatsoever. This is represented in the scene via an UnitController, which has an Unit as a property.

I also have an IDamageable interface, which has a Health property and a TakeDamage(int amount) void.

I'm not sure if my Unit should be the IDamageable, or if I should create a Monobehaviour attached to the same object as the UnitController, which would be the IDamageable and reflect it on the Unit.

What would you say ?

humble leaf
#

Personally I would make the UnitController implement it

mystic geode
#

Why that in particular ?

regal lava
karmic solar
#

You can have a UnitController class implementing IDamageable for strictly ensuring each unit is damage-able, or if you want to have more control over which units are damagable, create a separate DamagableComponent and add it to the Base Prefab of an Unit

#

then again, using an interface you can also just have "canBeDamaged" and toggle that, so I would go with whatever means less work for you

sly grove
mystic geode
#

Most of my objects live in a "pure-data world". The Units are plain classes. Most of my Monobehaviours only exist for "game view" reasons. All my types of enemies are not prefabs or gameobject for example, all the units (allies and enemies) share the exact same logic, except for the fact that enemies have a "strategy" that dictate how they behave.

karmic solar
#

I like doing seperate components once the complexity jumps up and treating them as universal blocks, where you can just Broadcast a message/create an Event on a specific function and have other components respond to it if necessary without any hard-binding and direct refs. If you document them in any way, you can have them easily adapted in other projects or parts of the game

I mostly use interfaces for GetComponent calls, but other than that I don't really touch them too much with unity since you cant serialize them

#

unless you want to go the serialize reference route I guess

karmic solar
#

I wonder if there is a hard-set preference that Unity recommends, performance or engine-wise 🤔

sly grove
mystic geode
# regal lava I mostly use interfaces for GetComponent calls, but other than that I don't real...

If you're trying to have a certain level of abstraction, interfaces can't be neglected in my opinion. In my game for example, both Units and Buildings are objects that the player can place on the map. Of course, they can inherit from an abstract class, but in the end it's so much more convenient to have the PlacementManager (or whatsoever) using IPlaceable instead of instances of a class

karmic solar
#

Agreed on the abstract class/interface, the worst thing you can do is tie yourself to a strict 4-level non-sense classes hierarchy, where the last guys hardly use half the functionality provided 😆

mystic geode
sly grove
#

Unit wouldn't be involved

#

except perhaps as a listener to an event that the Damageable script exposes

#

like OnTookDamage

karmic solar
#

you can have a TryGetComponent and have it fail gracefully, oryou can BroadcastMessage() that calls on anything if its there, e.g. onDamage

sly grove
#

i wouldn't use broadcastmessage

#

just C# events

mystic geode
#

Yes but the IDamageable would only live in the scene then, so for example if I'm calling a command like new DamageCommand(UnitA, UnitB, 2), I would have to access UnitB's Monobehaviour in a way or another right ?

sly grove
#

It's unclear what "UnitB's Monobehaviour" actuially is in this context

#

since you said you're living in a data-centric world with only some thin presentation layer presumably?

mystic geode
#

If I were using a Monobehaviour as the DamageTaker as suggested above, this would mean that the DamageCommand in that scenario would not accept the target unit as a parameter, but rather its DamageTaker component
So this would mean that to create a DamageCommand, I would have to access the Monobehaviour to pass it as an argument isn't it ?

#

In the scenario of a DamageCommand for example, it would seem logic to me that the parameters are "Unit owner, IDamageable target, int amount"
If the Damageable is a Monobehaviour, it would mean that my logic relies on my Unity Scene, which is what I'm trying to avoid in order to keep a data-centric world

karmic solar
#

if you need a 2-way communication, not just an invocation then it does make sense for me skip the seperate component and go with a direct interface, less ways to fuck it up

mystic geode
#

Unless I'm wrong in my logic 🐸

#

I think I'd like to avoid the 2-way communication
To me the ideal world would be that Units can damage each other, then the GameObjects in the scene listen to that and update the view accordingly

#

But the logic wouldn't have to know about the view

you can use the spline unity package to define the trajectory and move ring along it, after ring reaches the end of the curve start lerping it towards player's position

although I'd end the trajectory on the loop's apex point (or slightly past it), instead of going all the way down

I'm trying to integrate Google Play Games into my game and I followed every step, used the same app signing key as the one I used in my upload, tried disabling anti-piracy, overriding the proguard file, the android manifest file, etc. and I can't seem to log in. The following code:

PlayGamesPlatform.Instance.Authenticate(status =>
{
  Debug.Log(status);
});

ALWAYS returns with status "Cancelled"
I've also tried clearing cache and data on my Google Play Games app and that didn't work. I'm totally lost right now. Any ideas?

long ivy
#

ah yes GPG, where the error is either DeveloperError (incorrect signing key) or Cancelled (literally anything else has gone wrong)
Did you set up the OAuth consent screen with the right credentials and add testers? Also if you're testing on internal, your bundle is re-signed with google's key so you should have two signing keys

#

setting it up was a real pita because the info is scattered all over the internet

silk trench
#

And I just added my email to the testers

#

on both google cloud and play console

#

I've uploaded the app before, and I'm just making an update with the GPGS addition

#

and I'm using the same signing key to sign the build

#

And I'm using the fingerprint from that signing key for the google cloud credentials

#

(but I've also tried the public app signing key and the upload key given in google play console)

long ivy
#

App signing key cert = google's signing key, used for internal builds and releases
Upload key cert = sign your local builds with this
If you are only using one, then either only test track/production builds will work, or only local builds that you've signed with your upload key will work

silk trench
#

Right

#

I'm only doing internal testing right now

#

So I should be using the app signing key?

if you're downloading your build from the play store as an internal tester, yes

it does, then you should be using your upload key and signing your apk or bundle with that key

#

do you have multiple keys in your keystore? They should match

#

the other thing you should try is deleting play store cache on your device, delete your app, open play store again and make sure it's set to the right account. Then reboot phone

#

if the email it's signed into isn't on your tester list, you will also get that error and sometimes it seems to forget which one to use

silk trench
#

I've done all of that except reboot my phone

#

didn't work

so it must be an oauth thing ig

but I have the right key for sure

what scale is your spline at? maybe you just need more resolution? this looks like it works fine for a script I slapped onto a cube and move around a spline I made

var ourPosWorld = transform.position;
SplineUtility.GetNearestPoint(splineContainer.Spline,
    splineContainer.transform.InverseTransformPoint(ourPosWorld), out var nearestPointLocal, out _, 24, 8);
var nearestPoint = splineContainer.transform.TransformPoint(nearestPointLocal);
silk trench
#

@long ivy I figured it out

#

But it's extremely embarassing

#

My package name was wrong on the oauth consent screen

#

but to be fair, it's a really long name, so when I typed it in, I was just missing one letter

#

but now it works just fine

#

Thanks for your help

So I'm looking for some ideas to create a more performant type of effect system such that I've multiple time comparison operations going on. The most basic ways to create such a system is to just use a list and iterate over it and comparing a time variable. Another way is to create an independent coroutine for each effect, which is my current system, but it does create a lot of garbage such how much this system is being used.

So, I was thinking about some type of queue system such that only the first element is compared against for time, and if that one is popped we keep compare and continue popping the next few until we arrive at one which returns false. One problem with this is that not all effects have the same duration, so I can't be just throwing them at the end of the queue when starting a new effect, and another problem is effects which are triggered x amount of times in a duration, so I'd have to stick it back into the queue after it pops.

So, an ideal situation is have some bucket type container like a hash-set for quick insertion, but also ordered in a way like a queue so I only need to compare against the first elements. Any ideas?

#

some other ideas I had was just make a global container that groups effects by their duration or ticks, such that I'd have a group of 1 second effects, 2 second effect, 3 second effects, this way I have to check a max of # duration group effects every frame

long ivy
#

how frequently are you inserting elements? sorted list by soonest expiration time is simple and would probably work fine unless there can hundreds of effects; then maybe it makes sense to use a priority queue or sorted linked list

regal lava
#

talking about hitting like 300 units with a ticking type effect every 2 seconds for 10 seconds

#

as a single effect source

long ivy
#

so do you have 300 units, each with a list of effects on them? or 1 list with 300 effects?

regal lava
regal lava
#

but let's say I have 5 status effects that are ticking on 300 units every 2 seconds for 10 seconds for probably the largest sample im working with now

#

or add some variance and say two of those effects tick every 3 seconds for a total of 12 seconds

scenic forge
#

That's looping over 300 lists, that's tiny number for modern CPU which does minimum millions of instructions per second.

#

Are you sure you need something more performant, have you positively identified performance is indeed an issue atm?

regal lava
#

yeah it's probably not that big of a deal, I just find checking every frame excessive when these effects dont need that precise accuracy of execution

scenic forge
#

Well coroutine is not magic either, when you tell it to wait 2 seconds, it's nothing more than checking if the current time has reached the ending time every frame.

regal lava
#

right, I was reading more on them and yield waitforseconds still does check every frame

#

I was thinking there was some more sleeping optimization done with them but the underlying code isnt public

#

ill probably convert back to a single/multi list and play around with it since I've already been reading that coroutines also create garbage so something to compare against

novel plinth
#

With such amount of Lists I assume you're dealing with lots of structs
instead ArrayPool up. if you really love List due to it's flexibility of adding/removing, you can have a custom List with the backing array renting/returning to the pool (think of it like a pooledList)

#

lots of pooledlist impl on git or nuget you can take a peek at for this if you're interested

#

Personally I would just use arraypool for such scenario and ditch out List completely 😌

regal lava
#

Havent heard of that one yet, but I think a single list with large capacity should suffice. Maybe I'll make it a little more custom and add some dynamic capacity extension and clean up.

#

or perhaps some circular buffer someone keeps recommending me

Hey guys im trying to use the PreviewRenderUtility in unity to create a render of a 3D model but it doesnt seem to work no matter what way i try i was wondering if anyone had any idea why its not rendering the camera to a Texture2D?

i add the moels to a queue so im only using 1 PrefabUtility instance and 1 Render Texture for both the Model preview and the rendering of the images themselves due to the lay restriction, (I did try creating a prefabutility and a render texture per model instance but its not possible due to that)

 PreviewUtility.Render();
 PreviewUtility.EndPreview();

  AsyncGPUReadback.Request(_RenderTexture, 0, TextureFormat.RGBA32, request =>
  {
      if (request.hasError)
      {
          Debug.LogError("Error on GPU readback.");
      }
      else
      {
          // Create a new Texture2D and read the RenderTexture image into it
          _Texture2D = new Texture2D(_RenderTexture.width, _RenderTexture.height, TextureFormat.RGBA32, false);
          _Texture2D.ReadPixels(new Rect(0, 0, _RenderTexture.width, _RenderTexture.height), 0, 0);
          _Texture2D.Apply();
      }

      onComplete?.Invoke(); // Call the onComplete action
  });```

#

and you're calling this in an OnGUI somewhere?

#

maybe we should back up. What are you trying to do exactly? You want these previews in Texture2Ds for some reason instead of using this prefab utility thing to draw them in the normal way?

chrome sparrow
#

yes, im creating an asset for Converting Models to icons

#

the previews should be up in the top left corner after dragging them into the Drag Game object to preview here, you can adjust lighting camera angle and a few other settings at the moment. im having issues generating the icons in the top left at the moment. it seems to jsut skip the first one then on the second image it aplies the previous render to it

#

but its all blacked out and not how it should be

#

i am using 1 RenderTexture and 1 PrefabUtilityRenderer instance due to restrictions of layer usage with it

#

the rendering of the _Texture2D works fine, but if i try to run the icon preview generation it does not seem to work?

image.png
long ivy
#

are you generating Texture2Ds for them also, and just displaying that texture in the larger view?

chrome sparrow
#

yep

#

thats whats not working

#

for some reason this is what happens, the first render is blank, the second render is the first render, then the 3rd is the 2nd and so forth its like its not registering the GPU Callback and its coming back late and fetching the wrong render?

long ivy
#

well your use of the async gpu readback is fishy by itself. Makes no sense to do that until it's time to save to disk anyway

#

unless your tool isn't updating anything until you press the button? That would be a design fail imo, it should update immediately

chrome sparrow
#

i was having issues with the _Texture2D being captured by the render.

Essentially what happens is when you drag multiple models into the preview drop down section it addes them to a queue for processing, it setups up lighting spawns the model centers it based on bounding box, calls render then stores the image to each instance of the model in a custom class, once this is done it then destroys the model instance and repeats the process

          cameraDistance *= 1.05f; // Adding a buffer for better view

          // Set camera aspect ratio to match _RenderTexture

the whole thing with manipulating camera target texture and using RenderTextures and stuff looks like wasted effort. Did you look inside PreviewRenderUtility? It already uses a RT, and even has an EndStaticPreview that copies the RT to a Texture2D for you

chrome sparrow
#

yeh i did try that but that also was not working

#

would just render a blank image

#

The sequence of steps is this

If a model is already spawned destroy imediate, spawn the new model position it correctly infront of the camera, setup the lighting

render and set to the _Texture2D

but for some reason the _Texture2D is being assigned the previous render

#

actually i think i fixed it but all images are dark af >.<

#

in image preview this is what was happening the first render was blank then green was being rendered as red and this would continue the pattern

Does anyone know of an elegant way of matching the set bits of one int field by the value of another?
Kind of like math.countbits, but in reverse

public const int SIZEOF_ID = 10; // The amount of set bits in the bitmask
private const uint INDEX_BITMASK = 0b_1111_1111_11; // Corresponding bitmask

Right now these two values HAVE to match, otherwise things break. The code is performance sensitive, so I can't actually use math.countbits, and I would prefer they remain constants. It would be nice if I only needed to change SIZEOF_ID, and have the bitmask automatically be set correctly. Kind of similar to 1 << SIZEOF_ID, but where the trailing zeros are set to one instead.

#

I think I figured it out:

private const uint BITMASK_INDEX = ~0u >> (sizeof(int) - SIZEOF_INDEX);```

I got a problem with SetFloat

For some reason, when the character stops moving

#

the magnitude on the animator goes to like

44 digits negative

#

yes

#

Then it's scientific notation

viscid bramble

i know

but like

#

why... is it negatives

#

Shouldn't it stop at 0?

fresh salmon
#

Where's the negative sign located at?

when i debug.log() the inputmagnitude

it's "0"

Before the number itself or right after the e?

Okay that's just really close to 0, again, just how scientific notation works

If you transition to "end run", would it not make more sense to check that you're NOT moving AND that magnitude is less than 1.1?

Maybe you need another parameter, IsRunning

Hey guys. I've been looking into composition for this project of mine and I'm wondering if i could do the following:

Create classes that are NOT MonoBehaviour(save up on performance) that CAN be kinda dragged and dropped into a serialized field or reference and would allow me to set some variables on them in the inspector.

I dont want to use scriptable objects because i want data to be exclusive for each object

thin mesa
#

where would you drag it from if it were not a component or SO?
but you can just use a serializable type and serialize a field on a MB or SO to create an instance of it, or if you need some polymorphism for that you can use SerializeReference and some custom property drawers (or a premade package that does the drawing for you)

could i maybe add polymorphism to a list?

Does anyone know of a way to cull parts of a single mesh? I've only really found solutions on culling separate meshes

novel plinth
#

the convenient way is to chunk that mesh (assuming it's a single mesh)

jaunty swallow
#

yeah it's a singular mesh, the issue is that I create it from combining smaller pieces so I can batch them together

regal lava
#

well, similar to building, you can do the same by restructuring the mesh and reducing the verts and triangles

jaunty swallow
#

culling is not the same as restructuring though

#

my issue is that unity is telling me it is rendering a constant 1.1m verts no matter which direction I turn the camera

#

meaning it doesn't cull anything

regal lava
#

ah, right, usually breaking up the mesh and letting unity cull by what's visible towards camera's frustum is probably easiest, otherwise something like backface culling with a shader perhaps

jaunty swallow
#

the first way is kind of what I'm trying to avoid, I'm trying to cut down on the amount of game objects, I'll try the second way and let you know how it goes, thanks!

Not sure if this is the right channel to ask this, but I'm getting pretty absurd numbers in my memory profiles. Is this a leak? And if so, is it a Unity leak or is it a leak I could have caused? I'm using burst/jobs/native collections but as far as I know I'm disposing everything correctly.

jaunty swallow

well, it's a little technical but you doesn't usually cull by verts but faces. Usually you do try to Frustum cull first (wouldn't need to draw at all), and if it fails then you backface cull, though this is my experience for making voxel world stuff.

It seems to grow over time, which is what made me think it was a leak, but whenever I check task manager the usage seems reasonable, all the way up until Windows kills it. Its very strange

untold moth
#

I guess it could potentially mean that at one point unity tried to allocate that much memory at the same time and then after releasing it, it kept it as reserved memory.

untold moth
#

Also, are you sure that windows kills it and it's not an internal crash?

#

Often when you run out of memory, an allocation would fail inside the app, which would trigger some kind of segfault or other error that would then cause a crash. Or it could lead to some other undefined behavior, like an infinite loop(for example if you're awaiting allocation somewhere, but it doesn't happen). If the awaiting is on the main thread, the app would become unresponsive and windows would kill it after a few sec.

#

Basically, I'd try taking snapshots at different timings of your game, maybe even around where the crash happens. In one of them you'd probably see most of that memory actually being used instead of being in "reserved"

#

That's when you can track down the underlying cause.

On the animator, add the following script:

In the animation window, add a property for the script you created.

If the animation is coming from an external application (i.e. maya or blender), you can bake the property in the animation clip.

# pine topaz yeah i would like to, can you tell me what is the difference between CPU and GPU...

the main reason to use GPU is the extreme parallelism that they can achieve. modern GPUs have thousands of cores making it possible to do thousands of calculations simultaneously so many repeating tasks could be a lot faster on GPU. the two main disadvantages of GPUs are that 1. if calculation A depends on calculation B, it means B has to be calculated before A making it impossible to do them in parallel. Therefore many tasks are impossible to do in parallel and GPU won't speed up that process, the single core speed of a GPU is slower than the one in CPU. 2. moving data between CPU and GPU, especially from GPU to CPU is really slow. In games often times the reading from the video memory is done asynchronously because otherwise it would slow down the game too much so doing small tasks in GPU every frame isn't really a good idea. GPU is calculating something for millions of pixels or something similar to that. It could be used for mesh generation as well but often times the extra overhead is not worth it and simply multithreading on CPU is enough. I think Minecraft for example does the mesh generation on CPU (I assume the mesh generation code is such simple that moving all the data back and forth wouldn't be worth it)

Anyone have any idea why camera.ScreenPointToRay(screenPoint) is returning incorrect rays IFF camera.aspect < 1.0f?

The transform anchor shown in the top left corner has a stable pixel offset if aspect > 1.0f. But starts drifting if aspect < 1.0f.

afaik, my code doesn't have a bug.

var screenPoint = new Vector3(padding, camera.pixelHeight - padding);
var ray = camera.ScreenPointToRay(screenPoint);
            
var didHit = groundPlane.Raycast(ray, out var distance);

are you calculating padding based on an original camera width/height?

Even using the screen point 0,0 with no padding drifts away from the corner when aspect < 1.0f.

kindred tusk
flint quest
# kindred tusk how is that visible in the video?

Look at the transform axis in the top left of the scene view. notice how it stays a constant distance from the left and top edge when aspect > 1.0f. notice how that distance changes when aspect < 1.0f.

maybe it has to do something with dividing with screen aspect?

It's probably an assumption I'm working with being incorrect. Maybe.

Would be interesting to do a DrawLine from camera to groudn point and see if it always a single pixel/invisible

or if for some reason it's not perfectly parallel to the view

flint quest

Ya the debug draw is never visible from the game camera. So it is colinear with the view rays.

Seems like ScreenPointToRay just stops working with aspect < 1.0f.

The feature seems common enough that I figured it was a well known gotcha. I wasn't really looking for new debug ideas.

#

Fun fact: Disconnecting the game window from the editor seems to fix the issue.

#

So it was an editor only, window layout issue. gg unity.

since it's aspect ratio related, did you check your viewport settings? the video you showed wasn't even the view through the camera you're raycasting from so it's impossible to tell from that

stuck plinth
#

the scene camera isn't 1:1 with the game camera, turn on gizmos in the game view and look through that

You don't need to draw custom gizmos...notlikethis

#

You can enable the normal editor gizmos in the game view tab.

flint quest
#

Really? Never done that before. What is the entry under Gizmos that I need to turn on? They all seem to be selected by default.

hey does someone know whats goin on here? also my toolbars sometimes go invisible mainly my rotation tool

You just need to make sure that the gizmos button is enabled and have the object selected in the hierarchy.

Sibling directory to Assets. These directories can be deleted for a clean rebuild -> Library, obj, Temp, Logs.

Don't delete Assets if I wasn't clear lol.

# stable lark they're updated

Drivers being updated doesn't prevent you from having a problem with your GPU. Though I'd try to reinstall the editor first. But before that Confirm that the issue happens in a new empty project.

stable lark
#

yeah ofcourse assets its the main thing XD

#

but library i suppose

stable lark
flint quest
#

Did you try a blank new project?

stable lark
#

i went from 2022.3.18f1 to 2022.3.19f1

flint quest
#

If its a driver or install issue, it might manifest in a fresh project.

stable lark
stable lark

#

Also trying the project with the issue on a different computer might help narrow down the root cause.

#

If you have that option.

#

But I would try in this order. 1) clean build after deleting library. 2) blank new project. 3) different machine.

stable lark
#

deleted the library opening it and hoping that worked

#

doin that rq

Also if you are using DOTS, clearing the Entity Cache is sometimes helps hard to explain issues. Though I've never seen bad entity cache result in symptoms in the Editor UI.

it seems like its fixed for now

worst case scenario i'll just upgrade the version of the project and hope that fixes it otherwise i have no clue

kindred tusk
#

Yeah no idea. The layouts are shared between projects (but not editor versions)

i ended up changing versions and it fixed it for now

Unity in it's Unity.Properties packages has some nice abstractions over properties, however I have some unanswered questions pending:
How do I get values with the IProperty or PropertyPath? I see PropertyContainer.GetValue<TContainer, TValue>() but... I am afraid that passing the Base class type as TContainer won't really read from the actual runtime type Derived. Is this fear real and is there an alternative to that? Do I have to use a PropertyVisitor and Accept on that only for that?

Is there an efficient way to render lots of lines with Gizmos.DrawLine?

stuck plinth

does that also reduce render batches?

I guess I'll try and see, thanks

oh yeah that works great, from an extra ~20k batches to ~100 👌

Would anyone be able to help me convert a mesh generation system to utilize Jobs? I have a basic understanding of how the Jobs system functions so I’m primarily looking for someone who can give me advice and a push in the right direction

#

I am developing an in-game voxel level editor and I’ve reached a point in its optimization where Jobs seems like the best way to improve its performance impact and speed.

I have a weird problem. Lets say I have box, and in the center is a point. Each cardinal direction from the point goes to the scenter of each side. Now lets say if I want a line from the top right front corner to the scenter. I would assume to go in that direction I would rotate a line 45 right and then 45 up, but that isn't the case?

sly grove
#

What Vector are you starting with?
What do you mean by "rotate right" and up?

velvet rock
#

So starting with the rotation forward

#

Let me try a different angle here

sly grove
#

What are you trying to accomplish

#

And you're showing pictures here presumably of something you tried, but without seeing the code you tried it's really hard to know what it actually is you did

#

your description before "rotate right and up" doesn't make much sense

#

rotations happen around axes. They don't happen in directions. You can rotate around the x axis. You can't "rotate right"

velvet rock
#

Yeah it is a bit hard to explain. So rotate yaw 45 and then roll 45. I would assume the corner of the box would align with the line out, but it doesn't. Like the center of each face aligns, and I would think the corners being the meeting point of the face would match that trajectory.

sly grove
#

what are you trying to do?

#

Just make a vector pointing to the corner?

velvet rock
#

Yeah

sly grove
#

Take the local coordinate of the corner vertex. That is your vector, by definition.

#

normalize it if you wish.

velvet rock
#

I need to get there mathmatically though

sly grove
#

What's not mathematical about that

#

Let me ask you again - can you back up and explain what you're trying to do here?

velvet rock
#

Yeah that could help. I need to figure out if I should do that to get a square around the center, or do this. I need a perimeter around the center, and I was thinking the two perimeters would be the same, but now I am not sure which is better?

sly grove
#

What do you mean by "a perimeter around the center"?
A perimeter around the center of what?
What does "perimeter" mean? A measurement of the distance of the outside of something? What thing?
A set of line segments?
A shape?

velvet rock
#

I bounds around the scenter point. A specific distance out in the 8 intersects of regions.

#

Though I think I a seeing the issue

#

If I roll 45deg up lets say. it will align with the box's corners, and the sphere.

#

and then 45deg yaw globally it will match from the top.

#

But that causes this.

image.png
#

There is just some math principle here I am missing

sly grove
#

Well you'd have to actually show your code

velvet rock
#

What? no I am litterally doing this by hand right now to get to it by code. Also it seems 45 degree yaw and then 35 degree roll gets to the point. I am not sure why. Probably something to do with nature of 3D rotations vs 2D

#

Like that looks like a 45deg from the side views, but isn't 🤯

#

Someone better at Quaternions or Euler would have to explain this to me, but atleast I know what to do.

#

well 35.2643...deg

sly grove
#

What is this gizmo line thing

velvet rock
#

This is a visualization of a system I am making to get an angle of rotation to add to objects based on the average of the distances of walls/objects around it.

#

Basically take the rotation of the corner and weight it based on the distance of the collider from the center.

#

Oh you know why

#

if you took a slice of that circle and rotated it.

How can I access ScrollView from code? For example, to use ScrollTo method

I understand, that it's not a component, so I can't use GetComponent. So how can I access it?

Unity Documentation only shows example, where it's created with "new" keyword. But no example with accessing existing one from code

velvet rock
#

the projection of a 45deg roll would increase to 90, so you have to offset that.

misty glade
#

For CI based builds, what directories should I cache? I'm currently caching /Library and /Temp.. anything else?

sly grove
misty glade
#

If you're using UGUI scrollview - the docs are in a different place.. and you just set the normalized position of the content transform:

ScrollRect.normalizedPosition = new Vector2(0.5f, 0.5f); // note it's a 0-1 vector
#

for UnityEngine.UI.ScrollRect

patent sphinx
#

Then I assumed that I could use ScrollView class by accessing it somehow from code

misty glade
#

Yeah - that's UGUI

#

you can access it from code, yes

patent sphinx
#

But then I realised that ScrollView is not component. The actual component is ScrollRect

misty glade
#

oh, well, yeah, it's actually a bunch of things, but ScrollRect is the "parent" thing that you'll be interacting with to control it.. but there's a content component, a rect mask, scrollbars, etc

patent sphinx
misty glade
#

they're sorta the same.. when you create a "scroll view" from the right click menu, like that, unity just creates all the stuff for you - a parent with a "scroll rect" component on it, a rect mask, a child component that would hold all of the content, and it links the child content to the right place in the parent

#

here, example, lemme clip it and click around.. should make sense

patent sphinx
misty glade
#

it sounds like you don't want to access ScrollView - you want the component called ScrollRect

#

it's kind of weird, maybe unintuitive, but when you use the right click "create UI/ScrollView" thing - it actually creates a component with a scroll rect on it, which is the component that you want to access through code to .. move the content up/down

patent sphinx
# misty glade

Thx for example, but actually I already managed to achieve what I wanted with ScrollRect

So now my only question is what the hell is UnityEngine.UIElements.ScrollView 😄 Never encountered VisualElement before

Is that a whole different thing that is not connected with ScrollRect? Or is it something that exists "under the hood"?

stuck plinth
#

yeah, it's from the new UI library UIToolkit, which is totally incompatible with the old system and doesn't use gameobjects

#

it has a lot of similar features like buttons and scroll views so you have to tell them apart by namespace if you have both installed in your project

misty glade
#

right.. and UIToolkit is kinda .. more like xml/html for making responsive design layouts (as far as I understand it, anyway, I don't really use that library).. UGUI or UnityEngine.UI is .. something where you draw components directly to pixel/world/anchors and.. there's a whole different set of components

#

they're horribly named imho, and the documentation fragmentation on unity is a little hard to parse unless you know what library you're looking for or working with.. since if you just google "ui scroll view unity" who knows which one you'll get 😉

novel plinth
#

I do agree they can be very confusing yeah 😄

novel plinth
patent sphinx
#

By the way, about ScrollRect... I use it with VerticalLayoutGroup and ContentSizeFilter

All I want is when I add new LayoutElement, scrollbar should scroll to bottom

I kinda achieved this with:

scrollRect.verticalScrollbar.value = 0f;

But the problem is if I do it immediately after adding new element, it doesn't work.

Then I tried to set scrollbar value to zero after waiting for end of frame with Coroutine. It started to work, but weirldy only in 50% cases

Then I tried to do it after waiting for 2 frames. Finally it worked, but waiting for 2 frames looks like a bad workaround

Any better way to code auto-scroll to bottom when adding new LayoutElement?

misty glade
#

layout doesn't get recalculated until end of frame, so you have to wait 1 frame for it - alternatively you can force a canvas or component rebuild.. i forget the exact command, lemme dig it up

# 
RectTransform rt = (... your content's transform) as RectTransform;
UnityEngine.UI.LayoutRebuilder.ForceRebuildLayoutImmediate(rt);
patent sphinx
#

I'll record it

patent sphinx
#

It seems like it does scroll to the bottom, but sometimes it ignores the size of last added element

misty glade
#

is your content rect big enough?

#

your content gameobject won't just auto resize and get bigger.. it's actually kind of a pain in the ass to deal with.. i have a utility method for exactly this sort of problem, but it's not super well groomed .. you're welcome to look at it if you want

patent sphinx
novel plinth
# patent sphinx

what if you do Canvas.ForceUpdateCanvases after each button presses

misty glade
#

ContentSizeFitter should do it, yeah, but again, not sure what order these things get rebuilt

#

(typically at the end of frame - and if you're resizing/moving scrollrect content around, you might need to wait for multiple passes of resizing to happen - maybe 2-3 frames)

patent sphinx
patent sphinx
misty glade
#

i think the 2 frames thing is because contentsizefitter happens at the end of your current frame (1 frame) then the scroll rect size/normalized position recalculation happens at the end of the next frame when it sees a now-dirty rect (2 frames)

#

but i really don't know for sure and generally just .. don't care about the unclean interaction between these components.. if i need to dynamically load stuff into a scrollrect and I care about "being at the bottom" or "being focused" then i do it another way (like maybe making it expand upward instead)

#

so that the .normalizedPosition doesn't change

patent sphinx
#

Expanding upward sounds interesting

#

But I think I'll stick with 2 frames for now

#

Thank you

Hihi
So this isn't something im actively doing but im very curious of the "how" part of it

How do you code in a gacha aspect to a game (Ex: Pulling a character in a gacha game). Like the actual gacha part, throwing aside/assuming the needed materials to pull already exist.
How does it work

nothing crazy

I don't know if this is the right place to ask but for URP I find myself adding a lot of custom render passes

Is there a given template for it

Or any faster way to add custom render passes than to do the long process of adding like 3 scripts?

just regular animations. Not full blown character animations tho with like bones skin weighted whatever. it's for machines & buildings.
