and this is how i add to it

that was one of several possibilities I mentioned

and probably DDOL

SO like I said - a DDOL object

#

No?

#

If you do DontDestroyOnLoad it will make it DDOL

You are likely doing so in ChessBoard

Fixed Strings | Unity Multiplayer Networking

Netcode's serialization system natively supports Unity's Fixed String types (FixedString32, FixedString64, FixedString128, FixedString512, and FixedString4096). The serialization system intelligently understands these fixed string types and ensures that only the amount of the string in use is serialized, even for the larger types. This native su...

How do you do pathfinding in 3d space with moving objects?

tiny pewter
#

Just a graph that will change in run time

#

Then find out the most suitable data structures for the graph, probably octree

zealous panther
#

Say in A* pathfinding asset. Because the free A* pathfinding don't have much documentation

tiny pewter
#

Haven’t used that
(There should be some algorithm to generate “nav mesh” in 3d in form of 3d tetrahedron or AABB and reduce the number of Vertices significantly )

zealous panther
#

Built into unity?

untold moth
# zealous panther Built into unity?

There's no built-in solution for that. You'd need to find an asset or implement it yourself.
That being said, it's very rare for a game to use true 3d pathfinding. It's usually faked in some way.

maybe grab all the AABBs of the mesh of obstacles first, then a graph of only AABBs can be obtained, second for AABB of the mesh, project the triangles into the face of AABB and forms some triangular boxes or tetrahedrons, it should be a slightly easier approach, idk the detailed algorithm of generation nav mesh.

#

the space partition have bugs or cant handle all the cases, just an approach

eg if two AABB of obstacles collide....

What could be causing the second Debug.Log here not to print anything to the console, when the first Debug.Log prints? This is inside a coroutine that's doing stuff to a text. Trying to isolate the behavior because the "end" variable seems not to be working correctly in the for loop after, although it's not erroring out, it's just not going to the correct place in the text.

#

is what i expect to see, but then at callCounter 2

it's just this

why hide all the relevant code? I'll take a swing and guess you maybe aren't incrementing start and have collapse messages on or something, but you'll need to provide more for any real help

signal pelican
#

It's messy enough not to bother you with it, just wondering if there's a general thing that I might be missing. I don't think it's the collapse stuff

tiny pewter
#

then show the whole console windwo

#

or just merge them into a single call to debug...

Ok it was a simple collapse lol, should I delete that and pretend it never happened? 🙂

No, we need to keep track of people that make silly mistakes.

hello! does anyone here have experience on doing byte-range downloads with DownloadHandlerFile?

im trying to download a single asset bundle but i want to download it in chunks and then appending them when they're done. i have 4 instances of this coroutine running at the same time

When applying state machine pattern to a game.
Assume I have these states:
Idle, Walking & Running
What if I want to do something like if my player hp is less than 50% then he's injured and his movement is slow
do I make a new
InjuredWalking state? or how do I go about applying this

#

or do I track players base stats like hp, stamina & isGrounded and handle those within the same state?

tiny pewter
#

maybe, but if you modify the speed (or other stuffs) (it is transitions) you have created a new state implicitly

tiny pewter

If you have many stats that have to be modified or handle some specific logic then FSM may be better

I've never had a playfab project that had that issue

echo venture
#

Order of initialisation has been the source of a lot of problems in project starting from middle of production. Tips, suggesions or advice to tackle this?

sly grove
cerulean wasp
#

main thing is to try to avoid dependence on execution order

#

another is to bring things into existence as they are needed

echo venture
sly grove
echo venture
#

Indeed, but since this is a school project and they introduced code reviews quite late the damage was already done

cerulean wasp
#

You should modify script execution order, and only for a few super important classes that you know need to go first/last

sly grove
#

Time to go back and refactor a bit then

echo venture
#

and now not enough time is present to fix it fundamentally

sly grove
#

Well look, you've been given the advice you asked for

echo venture
echo venture
cerulean wasp
#

fixing bad code is always harder than writing it correctly the first time

echo venture
cerulean wasp
#

some scripts need to have defined execution order. Example: Custom physics solver needs to go last. Menu to control the whole game mode should probably go first

regal lava
#

system/managers usually non-dependent which would usually be awake

sly grove
echo venture
regal lava
#

but you may run into situations where you need a gamemanager (service locator for these major systems) to load first for these systems, so loup's suggestions for custom execution ordering

cerulean wasp
#

In general, the moment a script comes into existence, Awake() then OnEnable() get called

#

Start() waits a bit before going off

echo venture
echo venture
cerulean wasp
#

then you are working with people who wrote bad code

#

i once inheritted a 1000-2000 line script with highly technical calculations for a very specific machine. No comments, and all variables were just named a/b/c/d/e/f/g…

#

My solution: Toss it out

#

all of it. garbage

#

not salvageable

#

would take more time to fix than to make from scratch

echo venture
cerulean wasp
#

sucks. deal with it as a people issue. not a coding issue

#

let him know he fucked up

# echo venture Order of initialisation has been the source of a lot of problems in project star...

Order of initialisation has been the source of a lot of problems... for systems / managers and hooking gameloop events how can you avoid the execution order ?
when execution order matters, you're seeing hard, irrefutable evidence that

  • just because you can point to one piece of code and give it a name ("InputManager")
  • and then point to another piece of code and give it a name ("PlayerAnimationController")
  • doesn't mean that the two pieces of code are actually decoupled
    does that make sense?
#

for example, you CAN name this group of code playeranimationcontroller, and you CAN name this piece of code inputmanager, and then you CAN have them reference each other, and you CAN make a bunch of flags so that you mute certain inputs while certain animations are playing, and you CAN pipe a bunch of input state to the animation controller to show stuff at the right time

#

and you CAN make a dependency injection framework that somehow resolves this.

#

BUT that doesn't mean they're decoupled. they're strongly coupled. you just pretend that they aren't

echo venture
undone coral
#

so it's really hard to communicate this to your teammates

#

i haven't really succeeded. it's better to come in with a very strong opinion with a name for your tightly coupled thing

#

sometimes people aren't ready yet for the Morpheus-esque rabbit hole of strongly coupling stuff and being happy about it

#

it's easier than it looks. you can literally copy and paste the the code from one class into the other, and delete the old class

#

it's not as buggy as it seems, or take as long as it seems, and it also fixes a ton of bugs on the journey. you have to do that anyway. you have the bugs

undone coral
echo venture
#

Will read later

undone coral
#

basically there's an expanding brain meme
0. i have a Player class, everything lives inside of it, like the player's health, their input and animations

  1. brackey said InputManager and PlayerAnimationController
  2. i'm going to use dependency injection (or similar) to share controllers with each other
  3. i'm going to move everything to one class again, but only the things that really need to share state with each other, called FirstPersonPlayerController. it will be separate from a HealthAndEffectsController.
  4. all tightly coupled stuff will be in the same classes.

How can I set a constant Buffer in a shader?
I have a struct containing diferent variables that will be constant, and I would like to set them in one go to the shader

#

I created the buffer like this

if(SettingsBuffer != null)
{
    SettingsBuffer.Release();
    SettingsBuffer = null;
}
float[] setts = new float[] {
    vegetationSettings.ClumpingSize,
    vegetationSettings.SizeVariance,
    vegetationSettings.ColorVariance, 
    vegetationSettings.VerticalSize.x,
    vegetationSettings.VerticalSize.y,
    vegetationSettings.MaximumDensity,
    vegetationSettings.Slope.x,
    vegetationSettings.Slope.y,
    vegetationSettings.SlopeBlendFactor,
    vegetationSettings.MinHeight,
    vegetationSettings.MaxHeight,
    vegetationSettings.HeightBlendFactor,
};

SettingsBuffer = new ComputeBuffer(setts.Length, setts.Length*sizeof(float), ComputeBufferType.Constant);
SettingsBuffer.SetData(setts);
#

And then set like this

            IndexDistributor.SetConstantBuffer(VegetationSet.vegetationSettingsID, VegetationSet.SettingsBuffer, 0, VegetationSet.VegetationSettings.Size);
#

And defined like this in the shader

cbuffer vegetationSettings{
    float ClumpingSize;
    float SizeVariance;
    float ColorVariance;
    float2 VerticalSize;
    float MaximumDensity;
    float2 Slope;
    float SlopeBlendFactor;
    float MinHeight;
    float MaxHeight;
    float HeightBlendFactor;

With GBStudio

undone coral
#

i don't know what you expect

#

you can certainly blub your way into it. save the game, make the action in the game that changes memory, save the game, diff it

#

am i going to question the wisdom of deeply chasing a trend where there's one viral mcdonalds branded experience and one more retro gb studio experience? no.

oblique karma
#

Does the save function in UnityGB save the state of the game in the emulator? Because if that's what it does it's basically impossible for me to decode those changes right?

#

If the player is one pixel off from where i want them to be it'll be screwed up right?

undone coral
oblique karma
#

Well I guess if it's like an unchangeable screen maybe that'd have the same save state every time?

undone coral
#

you would modify the memory state directly. the saving is to give you an opportunity to analyze it

#

you wouldn't replace the whole memory, just modify a tiny part of it

#

i'm sure there's a way you can access the emulator memory directly

#

the gb studio people will know best

#

it's a fookin gameboy, it's going to just be addresses in memory

#

it's not like there's "reflection for ancient dead retro stuff"

sage radish
# oblique karma Yep

The Emulator class in UnityGB does not expose the virtual memory, but you would just need to make its x80 field public, and then you can access methods like ReadByte to read directly from some memory address. I don't know if GB Studio allows you to write directly to memory at specific addresses.

I'm not really understanding how to get world position of mesh vertices. I have a custom water wave function that uses a mesh of tris. I want the water to follow the player around but have waves work from world space instead of local space so that the ocean appears to be larger than it is. I have tried to use matrix 4x4 and Transform.TransformPoint but neither seems to be working (I'm probably not using them correctly) so any help would be appreciated.

Here's the full script without TransformPoint or Matrix attempts.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class Waves : MonoBehaviour
{
    public float linearWaveSpeed;
    public float linearWaveHeight;
    public float linearWaveLength;
    public float rippleWaveSpeed;
    public float rippleWaveHeight;
    public float rippleWaveLength;
    public Transform waveOrigin;
    Mesh mesh;
    MeshCollider physicsMesh;
    Vector3[] newVertices;

    void Start()
    {
        mesh = GetComponent<MeshFilter>().mesh;
        physicsMesh = GetComponent<MeshCollider>();
        newVertices = mesh.vertices;
    }

    void Update()
    {
        if (linearWaveLength < 0.01f) linearWaveLength = 0.01f;
        if (rippleWaveLength < 0.01f) rippleWaveLength = 0.01f;

        for (int i=0; i<newVertices.Length; i++)
        {
            Vector3 vert = newVertices[i];
            float dist = (vert-waveOrigin.position).magnitude;
            newVertices[i] = new Vector3(vert.x, (Mathf.Sin(Time.time*linearWaveSpeed+vert.x/linearWaveLength)*linearWaveHeight) + (Mathf.Sin(Time.time*rippleWaveSpeed+dist/rippleWaveLength) * rippleWaveHeight), vert.z);
        }
        mesh.SetVertices(newVertices);
        mesh.RecalculateBounds();
        physicsMesh.sharedMesh = mesh;
    }
}```

i haven't set the object to follow the player yet

#

i can make the water object follow the player but because the waves are using local coordinates, the ocean seems like a static object that follows the player. The idea is to "scroll" the area of the ocean that is "loaded in"

#

perhaps I'm still not understanding.

dusty wigeon
#

The water is following the player ?

molten socket
#

remember that vertex data does not have a transform. it is a vector3

dusty wigeon
#

Why would you use the vertex data ? You want the position of the player in the local space of the water dont you ?

#

What are you doing ? Because it does not seem like we understand each other correctly.

molten socket
#

the waves should be entirely based on world coordinates regardless of the position of the ocean object

dusty wigeon
#

Because you are working in local space and not in world space.

molten socket
#

yes

#

how do I get the world position of mesh vertices

dusty wigeon
molten socket
#

mesh vertices don't have a transform

dusty wigeon
#

The mesh is attached to a gameobject isnt ?

#

The gameobject has a transform

molten socket
#

ok so I would take the "vert" vector3 and run this function there?

#

tranformPoint seems to want a position rather than a vector3. Would it work if I make new transform data using vert?

dusty wigeon
#

No idea what you mean, but you want to use world coordinate then convert it to local space. So,
For each Vertex:

  • Simulate the ocean in a world space coordinate
  • Transform the vertex in local space with Transform.InverseTransformPoint
dusty wigeon
molten socket
#

ok so here's my loop, if I'm following this correctly.

        {
            Vector3 vert = newVertices[i];
            Vector3 worldPos;
            worldPos = vert.TransformPoint();
            float dist = (vert-waveOrigin.position).magnitude;
            newVertices[i] = new Vector3(vert.x, (Mathf.Sin(Time.time*linearWaveSpeed+vert.x/linearWaveLength)*linearWaveHeight) + (Mathf.Sin(Time.time*rippleWaveSpeed+dist/rippleWaveLength) * rippleWaveHeight), vert.z);
        }```
#

Vector3 does not contain a definition for TransformPoint.
using vert.Transform.TransformPoint(), vert doesn't contain a Transform.

dusty wigeon
molten socket
#

am I using the function incorrectly?

dusty wigeon
#

Use Assets from the asset store or try to use built-in function.

molten socket
#

assets don't have working buoyancy based on mesh collision.

You clearly do not understand the basics and I have a really hard time communicating with you because of that.

Is there a way to get something like Try Server (Method with only NetworkSerializable Params), which will simply execute the function when offline but can do a specified behavior if we are online, like simply calling the method on Server Rpc. I use this line of reasoning for my code all the time using ServerRpc so this in simpler terms would be very useful.

dusty wigeon
twilit grove
#

I know thats possible but I want to be able to TryServer without multiple functions and many lines of code. How would I even start coding osmehitng like this?

dusty wigeon
#

Also, a ServerRPC works in an offline call ?

twilit grove
#

it does?

dusty wigeon
#

Like, you do not even have to check if it is online or not.

twilit grove
#

doesnt seem to execute when I try it

dusty wigeon
twilit grove
#

Oh so i just needa learn clientHosts?

#

got it

dusty wigeon
#

You pretty much just need to spin the server and not expose it.

#

A.K.A the library. (The client is the server)

twilit grove
#

hmm... how would I do this exactly? and how would I, when I need to actually connect online, seamlessly turn off this?

#

would it be something like this?
Relay.Instance.CreateAllocationAsync(1);

dusty wigeon
#

You wouldnt want a Relay though.

twilit grove
#

true

#

so how would i do it without relay?

dusty wigeon
#

A relay is external server which client communicate through to facilitate connection.

twilit grove
#

NetworkManager.Singleton.StartHost();? how would I relably shut it down beofer game start

dusty wigeon
dusty wigeon
#

You need the host active

twilit grove
#

what about when you want to connect to another player's relay?

dusty wigeon
#

I do not know, it seem to me like you are asking the specific which you wont get there.

#

I can guide you with the general idea, but that is pretty much it.

# 
NetworkManager.Singleton.StartServer();      // Starts the NetworkManager as just a server (that is, no local client).
NetworkManager.Singleton.StartHost();        // Starts the NetworkManager as both a server and a client (that is, has local client)
NetworkManager.Singleton.StartClient();      // Starts the NetworkManager as just a client.
twilit grove
#

SceneManager.LoadScene(joinedLobby.Data["KEY_GAME_MAP"].Value);

        joinedLobby = null;

        JoinAllocation joinAlloc = await RelayService.Instance.JoinAllocationAsync(joinCode);

        RelayServerData relayData = new(joinAlloc, "dtls");

        NetworkManager.Singleton.GetComponent<UnityTransport>().SetRelayServerData(relayData);

        //MonoPlayer.monoPlayer.SetActive(false);

        NetworkManager.Singleton.StartClient();

        NetworkManagerUI.s.Destroy();

so running this code while a host is running would work correctly?

dusty wigeon
# 
Using an IP address of 0.0.0.0 for the server listen address will make a server or host listen on all IP addresses assigned to the local system. This can be particularly helpful if you are testing a client instance on the same system as well as one or more client instances connecting from other systems on your local area network. Another scenario is while developing and debugging you might sometimes test local client instances on the same system and sometimes test client instances running on external systems.

twilit grove

nvm

how do I start a host when my project is connected to relay when I dont want it to connect to relay for that startup?

spellGameObjects is a list holding the spells in player inventory

and SpellScript would be the spells script

lapis summit

but its obviously inneficient and searching in unity documentation and forums helped me little

livid kraken
#

Well if the type of so in each spell is the same, why not have a base SpellClass that holds the So snd other common spell data/functionality and have all your spells inherit from that

#

That way you can GetComponent on the base type and access the data regardless of the concrete implementation

#

But then again I dont get why your spells are monobehaviours in the first place

lapis summit
#

should they not be monobehaviours?

livid kraken
#

Depends. Why are they monobehaviours now?

Their movement

that is the forward force

and i have this shotgun type spell, where 5 mini-fireballs shoot consecutively

Hello, has anyone used before the factory pattern to provide "inflated types" to Monobehaviour types so that they actually can serialize them in the inspector?

#

Inflated types is the unity term for types that explicitly decide a type for their inherited generic types or interfaces

#

I'm trying to do all this because in unity you may either serialize a generic class with concrete type or a non-generic interface but not any mix of the two

#

So I thought I could add a factory somewhere that internally has inflated classes of the generic types I may ask for and returns these versions which are now serializable

#

But it seems like there is no escape to having to create a whole bunch of inflated types for every type parameter that may appear I my application and then doing the most awkward switch expression where I return a weird wrapper class that just is the same as the matched case but without the generic parameter

undone coral
#

you say serialize in the inspector

#

do you mean making a type appear when it is set on a field in the default editor inspector? i think you should just use a custom property drawer

#

it's simpler

tender crest
#

Yes, all this is to provide nice editor inspector serialization

undone coral

Why would I get faster rendering time with multiple draw calls rather than a big draw call?

regal lava
#

You'd find a balance through testing

tired fog
#

So is it possible? I thought that less draw calls > more performance

#

Because I'm currently finding that and it seems that for some reason, many draw calls is faster than one singular big draw call

#

And i don't understand why

sly grove
tired fog
#

No but im already doing that on both cases. So i literally have one huge draw call doing the same rendering amount as many smaller ones

#

But the smaller ones are faster than a single

regal lava
#

I've been doing some mesh chunking, and for the most part I do try to eliminate as many draws as possible by combining meshes. But, eventually it does become a problem when they are too large, as editing them has an increasing overhead for mesh manipulation.

tired fog
#

mmm, in my case im just rendering grass. So i have two options:

  • A: Smaller buffer, calculate one chunk, save index, draw and repeat per chunk
  • B: Big buffer, calculate all chunks, save all indexes, draw only once
#

For some reason, case A is faster

regal lava
#

UI has a similar problem were you can pretty much have a single large UI, but if you were to move an element it would dirty the whole canvas.

#

it's funny because resources point to trying to limit draws to about 50 or 60 on mobile, but usually you do want to cut up the canvas a bit more if you do have a large UI based game.

Can I get all methods with a custom attribute from all of the scripts used in a scene?

#

I know I could iterate over every object active on awake but is there a right way to do it?

sly grove
#

What's the use case?

zealous summit
#

I’m writing a custom in-game debug console and commands are added for it by an attribute

sly grove
#

So you're trying to intercept any method call with the attribute and emit a log when it's called?

#

Sounds like you want aspect-oriented programming

zealous summit
#

Well, not like this. I’m getting all methods (as MethodInfo), storing them, and invoking them using reflection when it’s needed

sly grove
sly grove
zealous summit
sly grove
#

Oh I see

#

you want to invoke a command

#

Shouldn't these be static methods then anyway?

#

Rather than related to objects in the scene?

zealous summit
#

Some, sure

sly grove
#

If they're not static how do you know on which object to invoke them?

zealous summit
#

But the user might want to put it on the monobehavior

zealous summit
#

So it knows what class contains this method

sly grove
#

but if I write shoot in the console how do I know which character will shoot for example? All of them? Or do I need to say character --withName "Gary" shoot or something

zealous summit
#

Didn’t really think about yet

#

But you make good points

sly grove
#

Limiting to static functions seems like a good starting point

#

in that case you can basically just do SomeClassInMyGame.GetType().Assembly then search all classes in the assembly and find all static functions from there with the attribute.

zealous summit
sly grove
#

sure

#

in either case I would use the assembly as the starting point for your reflection search

#

rather than enumerating objects in a scene or any other Unity concept

zealous summit
#

Alright

sly grove
zealous summit
#

Do you know how the default Unity user assembly is called?

sly grove
#

or rather typeof(SomeClassInMyGame).Assembly

zealous summit
#

It would be a good solution, but I have a separate assembly for my console because it’s in a Unity package

sly grove
#

In that case I would probably do something like:

public void InitWithAssembly(Assembly a) {
  // do all your reflection here
}```
#

and call that from your main game code

zealous summit

Alright, thanks for advice

its ToString is showing "null" for idiosyncratic reasons related to how Unity overrides ToString and equality comparisons with null

the situation where this is really null can happen, which ahs nothing to do with unity, but you haven't shared any code

so i can't rule that out

#

it's very very hard to get into such a situation

#

so it's extremely unlikely that some layperson on the internet using unity got there

you are almost certainly stepping through a coroutine, and you almost certainly have code which calls Destroy on the game object

#

at some point

# tired fog For some reason, case A is faster

How do you sort them? The order in which things get drawn affects how much work the GPU does, because of overdraw. When drawing opaque objects, you want to try to draw them front-to-back, so the GPU doesn't waste time shading pixels that will later be obscured by another object.

undone coral
#

usually people do void OnDestroy() { ... GameStateMachine.OnPreround -= Preround; } but honestly just don't use C# events, call the thing directly.

exactly for this reason

sage radish

OHGHHH I GOT IT! tysm

undone coral
#

just think very deeply about "destorying an object does not unsubscribe it from C# events"

it was just cause I "refreshed" objects by reinstantiating them which made it look like the refreashed object, not destroyed, was calling that but instead it was the object pre-refresh.

But if in both cases they are all drawn the order doesn't matter (because it affects the both comparisons equally)

In any case, the case where I was doing the check there was no overdraw possible (since none where occluded by anything else or themselves)

sage radish
sage radish
tired fog
#

I'm actually , when doing all the calls, doing draw call of material X, draw call of material Y, draw call of material X, draw call of material Y,... because of LOD's, so set pass is bigger, and performance doesn't change (it stays stil slightly faster)

tired fog
#

I'm just gonna stay on the multiple draw calls, for some reason it stays slightly faster and memory consumption is extremely different (I can do the multiple draw calls in just 20Mb, while the single draw call requires minimum around 800-900Mb or more even, for a 1 frame difference at best)

But it's weird, will look further into it on the future

Any tips on how to approach the third step on this? It's suprisingly difficult for me, as doing pure distance checks either are extremely nested, or fail because of members of the squad moving away together, therefor always having someone close enough to not be considered outside of bounds.

knotty salmon
#

Yes, when they move together they check if they are in opposing squads, and merge into one.

dawn zinc
#

How does the player disconnect from a squad?

#

distance? keybind? obstacle?

knotty salmon
#

Distance

dawn zinc
#

well if the issue is that they never get outside of the boundary to be out of bounds, just sounds like the second squad pair just moves too fast and keeps up with the first squad pair

#

so you'd probably want to slow down all secondary squads

#

or speed up the main squad as it collects squads

knotty salmon
#

No, not the issue of speed. Its finding a way to detect if your outside the group or not, if someone is near you, but he also is to far away from the next member etc etc. its a very nested thing, with each iteration requiring checks to every other squad member making it more expensive. I was wondering if there is any tricks I have missed. Maybe some kind of pathfinding between units to see if there is a valid connection is the soloution, I havent tried that appoach yet.

dawn zinc
#

if you're just checking when it's too far away could you just use a collision trigger around the main squad and whenever something exits that trigger aka goes outside the boundary you can disconnect that squad

#

probably just a sphere collider

knotty salmon
#

There is no main squad, they are all the same, and split into two

Not sure what right channel for this question is, but we are changing scripting defines in a custom build script when running build from cli using PlayerSettings.SetScriptingDefineSymbols. The problem is that the changed script defines arent being reflected in the code during build, so its not properly refreshed. I tried all things like manually calling refresh on assets, or even trying to trigger a script compile. Only way I have gotten it to work is to do it in 2 seperate cli calls, where the first one only changes the script defines, and 2nd does the build. But its really not an optimal flow as it adds lots of overhead to build time. Anyone encounted something similar, and how did you solve it? Only other fix i can think of is making the script define changes directly to the ProjectSettings.asset from external code

long ivy
#

how much overhead are we talking? I'm currently doing it in one pass like you want and was actually planning on switching to two passes instead because I think it'll be simpler and more reliable

#

but atm I'm just using a build method that:

  1. locks assemblies
  2. applies scripting defines
  3. saves session state so the build will resume after domain reload
  4. unlock assemblies
  5. force assembly reload

Then in a [DidReloadScripts]-decorated editor method, I check those SessionState values and resume the build, but now with the changed symbols

lethal stirrup
# long ivy how much overhead are we talking? I'm currently doing it in one pass like you wa...

How do you do that third and fifth step?
I mean, its not a crazy overhead, 3-4 mins, but for us we want to have as fast build times as possible since its a key part of our CI/CD process, so I rather not do it like that. I now have a python script that changes the values directly on ProjectSettings.asset instead. Found a python module called unityparser that helps me make the changes "safely". Annoying that its not standard yml 🙂

I like the python option though, that seems like a clean solution

If I'm creating, using and disposing a native array of temp job multiple times, would it be better to create it once as persistent and reuse it?

grizzled lake
sage radish
# tired fog If I'm creating, using and disposing a native array of temp job multiple times, ...

Creating temp arrays instead of persistent arrays can reduce how much memory your game needs at the same time. For example, if you have five separate systems running sequentially, and each needs their own 200 MB array to do some work, they could save processing time by allocating their array once and reusing it. But then you have five 200 MB persistent arrays allocated at the same time, at a total of 1 GB. If they each used a temporary array, then you'd never go over 200 MB of allocated memory at the same time.

#

You can reduce allocation time by specifying uninitialized memory, which can make a difference when allocating a lot of bytes.

Adding CommandBuffers to Lights and Cameras is a simple way to hook into an otherwise closed off pipeline like the built-in render pipeline. But it's also limited; you can't run any code during those events.

URP is an entirely separate render pipeline, so they didn't choose to remove support for CBs on lights and cameras; they chose to not reimplement it and instead created Renderer Features.

#

This is a common theme in Unity's development. Start with something simpler, run into limitations, reimplement it to be more flexible, optimized, but sometimes more complex or boilerplate-y. See GameObject/MonoBehaviour -> ECS

#

It's more work to get started, but allows for more control in the long run.

Hi all, I've got a best practices question.

I'm making a builder game prototype where you click an object to select it then drag it around the screen. Selection is done via a ray cast from the mouse through the camera. The ray returns the objects collider, then I transform the position of the object every Update.

My problem is the transform between the parent and the child objects getting out of sync. Ideally, I think I want the child transform to be static, and the parent to be used. However, I've got my rigidbody attached to my child, so the parent transform will always stay static, but the child transform changes over time as gravity is applied to it.

Below are 3 examples, I'm currently using A. Is there a 'best practice' way to organise my components?

I've set up a button that calls SignInWithSteam(), which then gets a response in OnAuthCallBack with Steam login successful.
But after that I don't know what to do next?

I finally got it to work, no idea if I'm doing it right, but it logs me in and I can get my player id so I guess it works.
Still no clue what half the variables in the doc are for:
both m_AuthTicket and m_SessionTicket are never used as far as I can tell

#

And I really wonder what this is supposed to do, I assume it's a typo on the doc page, but no idea what it does or if I need it

m_AuthTicketResponseCallback = null;```
#

I changed it to m_AuthTicketForWebApiResponseCallback which is defined at the top and actually used, but dunno if it's intended like that

#

Feel free to PM me if you know more about Steam login and can help me set it up properly

Has anyone ever worked on a fighting game before? For hitboxes I'm currently using OnTriggerStay (which has consistent results), to activate my hitboxes I'm using a coroutine who's timer is synced to the regular timescale which leads to inconsistencies. The reason why I'm not using FixedUpdate or fixed deltatime is because I'd like to be able to slow the game down and the main timescale but keep the hitbox logic the same (currently not the case and with fixed update they'd lose sync).

If i'd like to achieve this would I be able to utilise a 3rd "Update" for hitboxes which is called inside Update() and only fires after its own time delta has passed? I already see holes with it so if anyone knows a way to implement an additional custom fixedupdate or has a better suggestion please lmk

#

I know limiting the frame rate is an option along with throwing out scaling deltatime too so if that's the most sensible option do lmk

grizzled stag
#

Ohhhh, I'm a goober, fixed deltatime is scaled properly, should be able to solve it now

Hey guys, this is a bit of an SOS because I really don't know what to do here.
If I can't figure this out, I probably have to scrap the months of work I've put into this project, because it is integral to the end product.

Context

I'm using Unity and the Timeline in a project made exclusively for video. In this video, I have a virtual screen that needs to play back certain video clips while recording.
Thankfully, Unity has included custom Timeline sample scripts, some of which can sync a video component's playback to the timeline. Since I am recording the playback of the timeline, this is useful.

The Problem

It is barely functional, in that it can only work in extremely rare cases and in most cases it just straight up doesn't even try to play the clip. I believe it was designed for realtime playback in things like games, but since in my application I would prefer that the graphical fidelity is high and the timeline plays back slower than realtime (especially with the performance cost of the built-in recorder codec im using), it seems like the video player just cannot keep up.
It seems like the way the playback works in the timeline is that it just tries to make the video player go and attempts to sync the video playback position if it gets out of sync.

What I need

If anybody with the necessary experience might be able to help me alter the sample video playback script, or develop some alternative solution, so that I can guarantee that the frame doesn't finish rendering the frame until video playback has caught up and is on the correct frame, I would really really appreciate that. Any amount of guidance or assistance is appreciated because I am very stumped here.
Splitting each individual frame into images manually is also not a viable option here. I need the ability to just drag and drop videos into it and have them play. Worth noting that I haven't transcoded those video clips because Unity transcoding quality is dogshit even at the highest possible quality to the point where it is completely unusable. Every single one of these clips are 1080p60 NVENC H.264, encoded on the same hardware I'm trying to play it back on.
That being said, I do not need the audio from these clips I'm pretty sure, so while it might be a nice bonus it is not necessary.

What is attached

I've attached a little video of me demonstrating the problem, along with a zip of the scripts included in 1.7.5 Timeline customization samples. I'm fairly certain I haven't modified any of it.

📎 Video_timeline_customization_sample.zip
#

Alternatively if anybody would know a way to ensure that each frame in the video will definitely appear properly with a normalized value between 0 and 1 indicating progress through the clip I think I would have code that can provide that value to a script, in case you have no timeline experience or something

fresh vortex
#

tldr?

dusky kettle
#

i mean its mostly said in the What I need bit

#

the video player isn't playing back properly with the unity timeline

#

and this is being used for rendering a video so i need a solution that will definitely work when the playback is not running at the frame rate that the timeline is set to

#

youd probably need the context of what i wrote in that message though just so you fully get whats going on and dont offer solutions that arent really for the problem

dull fossil
#

Have you looked at not using the video player and instead something like a Raw Image component that would display a render texture of the clip? Sorry I'm on my phone and so can't watch the video or really try to understand the problem, but that might be a possible avenue to look at a bit closer since I've also had issues with the video player. (though for a completely separate problem)

dusky kettle
#

i mean thats a way of doing it, I do specifically need to use a material for a 3D model though

#

the main problem is writing the code that will take a video clip and display each frame properly in sync with the timeline

#

not the way it's being rendered

#

and as I said in my original post manually splitting each clip into frames is also not a viable solution here

#

so id need to do that individual frame reading at runtime

#

and it seems that the only way to get frames from a video clip at runtime is to use a component like the video player

#

oh i have an old project that had something similar to this lemme try dig that up and see if I used ffmpeg in a way that can be repurposed here

#

oh looks like i actually might be able to

#

idk where the ffmpeg package from the asset store went though

#

oh its deprecated

# dusky kettle Hey guys, this is a bit of an SOS because I *really* don't know what to do here....

Your use case seem to not be suitable for what the Video Player/Timeline has been made for. As per your test, the Timeline and VideoPlayer might have some assumption that are not being respected in edit mode. That being said, you might be able to do something more hacky by using the VideoPlayer.StepForward or/and VideoPlayer.time and a custom playable implementation.

To diagnostic what is happening, you could always try to hook to some the event.

dusky kettle
#

yeah i think in this case I'm going to try and adapt the video player timeline sample to utilise some code I wrote in a previous project that extracts each frame from a video at runtime and just do that instead

#

the main thing i still need to figure out is how to ensure that the timeline will freeze until the video's frame has been rendered but i think i can try figure that out

#

this might be what i need actually

this is so busted, i believe your machine is misconfigured

#

have you tried building the player and running it on e.g. a macos device?

#

Every single one of these clips are 1080p60 NVENC H.264,
@dusky kettle can you try converting one of the files to intraframe only using

ffmpeg -i input.mp4 -c:v libx264 -x264-params keyint=0:min-keyint=0 -c:a copy output.mp4

although it would be best if you installed the h265 codecs from the microsoft store and encoded with h265 intraframe only:

ffmpeg -i input.mp4 -c:v libx265 -x265-params keyint=0:strict-cbr=1 -pix_fmt rgb444le -c:a copy output.mp4

your machine might not be fast enough for multiple h265 intraframe 444 streams

#

i have no idea if these exact ffmpeg invocations will work btw, but they should be close enough

#

Looking for advice... I'm using the workflow for buttons that does the good old .onClick.AddListener thingy... So for example there would be Button MyButton; and then void Start(){ MyButton.onClick.AddListener(OnMyButtonClicked);} and finally void OnMyButtonClicked(){ // do something } Or something like that, you get the idea. Now imagine that I have 20 buttons like that. Adding and removing them is suddenly not very nice, since you need then to add/remove those delegate shenanigans from Start/OnEnable/OnDisable. Any ideas to refactor this or change the approach to avoid the hassle ? I thought maybe just make an array of serializable class that has reference to buttons and to some Actions, but then I still need to add listeners manually each time... any ideas??

kindred tusk
#

In my games the UI usually persists for the entire runtime of the program so there's no reason to deregister listeners

That said, I have had this problem before and it definitely sucks, there are things you can try to bulk unsubscribe, but it really depends on your architecture at to what is best. Best imo is to sidestep the problem as I describe above.

Anyone know how to disable culling from Graphics.DrawMeshInstanced?
I know the doc say it shouldn't do that, but in my case it clearly does some unwanted culling, and looking at the net it's apparently been a thing since 2020 - so I guess it's not a bug.
Is there a way to disable it? I can "fix" the problem by editing the impacted meshes to have ridiculous bounding boxes, but that's impractical as hell long-term AND it mean a big bunch of uneccessary calculations are being made somewhere inside Graphics.DMI

Although a very simple way to ensure a mesh won't get culled is to just center its bounds to a known visible point.

eh iirc 4444 is only if I really need almost perfect quality and that's not important here, the issue is that the video player on the timeline just straight up wasn't working, so I built a custom timeline thing that just buffers the frames and freezes playback until its done buffering everything so the timeline unity recorder integration can actually capture the video playing back through the 3d scene

It does, and I can find this bug been mentioned on reddit 6 years ago, and on Unity's own forums 4 years ago.
So clearly they either don't care about fixing it or it's somehow intended behaviour despite the documentation saying otherwise.
Been asking a bit everywhere and apparently no one know how to actually fix that. Guess I will just have to use another API than Graphics.DMI, which is a bother.

untold moth
#

The only thing that this call saves you is creating objects with renderers.

fickle mountain
#

It still result in objects spread across an entire football field being culled out when the camera is pointing right in the middle of them.
And having to check every mesh that will enter the system for correct bounding box is extremely annoying work-flow wise, especially since Mesh.RecalculateBounds doesn't actually calculate something valid and you have to manually decide the box's parameters.
Guess I will just follow Reddit's solution of blindly forcing huge box on everything, but that's such a dirty way to dodge the problem, for something that should just have a boolean Culling/NoCulling parameter somewhere.

ancient solstice
#

Maybe Graphics.DrawMeshInstancedIndirect is an option for you, I know that Unity definitely does not cull that because I had to implement frustum culling myself

Hello everyone!

I'm trying to figure out a way to detect objects within a certain shape. I've researched/used various collision detection methods, like triggerEnter/Stay, overlapShpere and overlapBox (onCollisionEnter/Stay does not work for me since I don't want to use unity's physics engine for my colliders. I want the colliders to detect, not interact).

Anyway, I'm leaning towards an overlapSphere/Box system, because it's what's closest to the way I want things to work, but I have a couple problems with it.

  • Problem 1: I want to detect positions in 3D space, but ignoring the y axis, so no matter if u are jumping or on the ground the game should recognize the collision based on x and z.

  • Problem 2: I don't always want the check to be a box, and because of the problem mentioned above, never a sphere.

  • Problem 3 (very tied to problem 2): I want to be able to use custom shapes, for example detect in a "Triangular Prism" shape, or a rectangle.

I have considered a very basic solution, but I really dislike it:

Use an overlapBox where the bounds are set to the maximum bounds of whatever shape I want, and with a comically large height. Then, from the gameObjects that exist in the overlapBox, check each one and determine if they exist within my custom shape, done by code.

I really dislike this since it's a very hacky solution, but I've not been able to figure out something better yet.

My ideal situation would be to create a gizmoz tool that allows me to add verteces and create a shape (kind of how a line renderer works) directly in the editor, and then to be able to read this shape in the code and use it to detect every gameObject in it. Any ideas?

regal lava
#

So basically mesh colliders but never move them from the y axis

#

or you mean the collider can be a box shape but you want to check if collided object is of shape circle which is just a type check

pulsar crane
#

I've thought about mesh colliders, but then I'd have to use triggerStay, when all of my actions essentially need to check the colliders at a certain point. I'm aware that I can save the intersecting colliders and act on them only when I need to, but I really don't want to check for them every frame since I don't need it.

And no, I don't care about the collider object's shape. Her's a sinple drawing, where 1 would be the overlapBox, and 2 would be the actual hitbox I want. The overlapBox would give me objects 3 and 4,and I'd have to loop through them to check if they exist within my "custom shape".

This already comes with a set of compromises, for example the fact that I'd have to set the overlap box to a very high heit to have a way to "ignore" the y axis, but it would also mean that the object exact position would have to be inside my custom shape, and not their collider, which is a box, or sphere, not a point.

My question exactly, is basically, Is there a method, custom or native, that works like overlapBox, but that allows for a custom shape?

My question exactly, is basically, Is there a method, custom or native, that works like overlapBox, but that allows for a custom shape?
approximate the shaep you need using the overlaps. there are approaches that can do this. you can download an asset from the asset store which can create multiple-box-collider approximations of mesh colliders, then use it for overlap box invocations instead.

it sounds like you are building a 3d platformer game, like super mario galaxy, and you want to design regions of the level where there are certain effects on the character? can you give me an example of why it's essential that these regions be highly accurate?

pulsar crane
# undone coral what is the purpose of all of this?

Hi,
I don't see how these are different problems, my goal is to detect colliders inside a custom shape instead of a box or sphere. And no, it's not a 3D platformer, it's a MOBA style game. So hitboxes can adopt varius shapes, but they need to ignore the Y axis.

In the time since I've posted this I've figured out a way to accomplish this, I'm creating a custom 3D collider script that allows me to define a shape using gizmos and a number of points, however I've decided to have only triangle and square shapes. I'm going to use various square/rectangle shapes to create custom hitboxes, same for the tringles.

As for how it's working, I'm going to implement the detection of both shapes with the overlapBox, and in the case it's a triangle I'll check if the object is within an "internal" triangle (see the paint above). This will defiently fit my needs, and even if it's not a native feature, it won't really be that distant from using a normal overlapBox, just with easier customization.

I'm aware I'm terrible at explaining myself...

Anyway, thanks for trying to help! I really do appreciate it

undone coral
#

i know what a MOBA is, so just answer succinctly how you would use this custom shape detection

#

i'm not asking how it works. here's an example answer: "i want a way to design areas of the map that slow down movement, make your character hidden" or "i want a way to design AoE regions"

yep league is about 0% transparent on how their code works, very understandable since 99% of it is pure garbaje. So yeah, if u are familiar with league, imagine a cone shape ability (panthone e, yone w, etc etc). That kind of detection where you need to know what is inside this cone at exactly the time that is casted, not have it constatly check enemies for when and if it's casted.

But as I said, I'm already working on the implementation explained above, If you have a better sugestion I'm all ears

you are saying cone, but i don't think you mean the 3d object called a cone. you are using gamer jargon for a programming problem

I've also told u league is not transparent about their code, specially since they don't even use a game engine for the game so whatever they use is not applicable. Just because u fail to understand or grasp the concepts I've put down here does not mean it's because I've used "gamer jargon" for refering to a triangular hitbox as a fucking cone.

Are you under the same restriction as this comment from Valve described?
Can't get the wrist bone transform, as this is affected by the resulting physics.

#

As in, do you only know the local position of the wrist relative to its parent bone?

#

You can't get the world position of the wrist easily?

I suppose I am, since I'm using their SkeletonBehaviour to drive the finger bones. But i just god the idea to spawn their skeleton as is, not render their hand and manually drive my bones from the positions of their bones.

i'm not sure what you mean by buffering frames, it sounds like you are blitting the video to a texture, then putting that texture on a material and using that instead

#

so to start, it sounds like you did not correctly set up using videos at all when orchestrating the videos using the timeline based on whatever unity documentation you read

#

is that correct?

are you asking me if I set it up wrong? lmfao

can you answer the other questions

what do you mean by buffering frames?

its just like

so the ffmpeg for unity asset store thing I used has a GetNextFrame() feature

the "VideoTexture" you can just manually step through the video

which returns a Texture2D?

dusky kettle

so i just use Graphics.CopyTexture or whatever it is

to a render texture?

and buffer exactly all the frames i need into a list

which I then display based on where the playhead is

Hi all.
I've got a problem with the assembly stripper after updating my Unity editor version. Suddenly it began to strip out one of my assemblies and the error log helped me with that:

Fatal error in Unity CIL Linker
Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'SuperSocket.ClientEngine, Version=0.10.0.0, Culture=neutral, PublicKeyToken=null'

Now I added my link.xml file to include:

<linker>
<assembly fullname="SuperSocket.ClientEngine" preserve="all"/>
<assembly fullname="SuperSocket.ClientEngine.Core" preserve="all"/> <-- somehow the name of the lib doesn't match the namespace so I added both
</linker>

but now I get again an UnityLinker exception, but this time just a null reference without any information where to search for. Anyone a suggestion?

# verbal wren Try deleting your library folder (within the project) and reopening the project ...

Thanks for the suggestion. It was something different though:
The error is actually the "wrong" name of the assembly as it seems. While the assembly name is SuperSocket.ClientEngine the file name had the .Core suffix. It seems like the linker was searching for the assembly file with a matching name and couldn't find it. So without the link.xml it was throwing the assembly out completely as it couldn't find the SuperSocket.ClientEngine.dll assembly (due to the suffix of the file name) and with the link.xml it was complaining that was able to find the file, but it was not matching the namespace.

Sounds weird, especially as it was working in former editor versions and I wish the linker would have given out a better explanation instead of just throwing out a null reference exception 🤷

Does anyone know the best/most easy way to create a game that is compatible for both regular 3D PC players and also VR?

Is it even possible to do this easily? Or, should I just create 2 builds for the game, one for PC and one for VR?

This question is mainly about singleplayer games, but I would be interested to know how easy/possible it is to make a cross-platform game for XR and PC

#

Then just instantiate the correct one based on the chosen mode

#

From a game design perspective it's not necessarily simple but from a code / architecture perspective it is.

Maybe show the option for VR controls only if a VR device is plugged in but give the player the option of what they want to use between the two

I haven't actually tried anything yet, but does anyone have a solid way of "parenting" rigidbodies without physx constraints/joints?
Like a jet landing on an aircraft carrier, or something

sly grove
plush hare
#

that still sounds really janky

sly grove
#

it depends exactly what you're looking for

#

if you want it to just be solidly "parented" like a Transform parent relationship, you can get that if you make the child kinematic

plush hare
#

nah it needs to be actively simulated.
Some guy on the forums made a post about this, and he tried just mimicing the velocity and other things

#

and couldn't get it to work

#

unity's implementation of physx is very strange altogether

#

like if you set the position/rotation of a sleeping body, it will automatically wake it up and add velocity

#

even if the position offset is just + new Vector3(0,0,0)

tall ferry
# plush hare nah it needs to be actively simulated. Some guy on the forums made a post about ...

If the objects are physically touching and both moving via physics then I think this approach would be flawed from the start. Like the example you said, jet on an aircraft carrier, the "parenting" would happen when the jet is touching the top of the carrier. The carrier moving would cause friction on the jet, and any rotations wouldnt make sense to mimic directly unless the plane was exactly on the center

plush hare
#

in terms of parenting

#

maybe my tests were flawed

#

like if you move the bottom body, the top one just stays in place

tall ferry
#

Friction should be slightly affecting it, which you would probably want to set to 0 if mimicing velocity. The only issue I see would be that you constantly need to assign the velocity of the top body which might mess with collisions that happen

#

Rotations would also definitely be an issue

If I have a height map for a terrain, that has full position values, how can I calculate normals the right way? I'm trying this to calculate each normal but I get black squares at the edges because it has the incorrect normal

Vertex v = vertices[i];

int y = i/Resolution;

var posA = position(x-1, y);
var posB = position(x+1, y);
var posC = position(x, y-1);
var posD = position(x, y+1);   
var centerPos = v.position;
var normalA = cross(posC - centerPos, posA - centerPos);
var normalB = cross(posD - centerPos, posB - centerPos);
v.normal = normalize(normalA + normalB);

Hello, i have a problem with a variable that reset every frame with the value that was set in start() (stay at false) but there is no line where i set this variable to false i checked with ctrl + f and its a private variable. the code contain with the monobehaviour class, an editor class.

📎 S_MovingObject.cs
#

im kind of new with the custom inspector and i hope it isnt something in it that mess it up

#

Not an advanced issue, but remove all other debug.logs and replace the isMovingNow definition with this and show what it prints:

private bool _isMovingNow;
private bool isMovingNow
{
    get => _isMovingNow;
    set
    {
        if (_isMovingNow == value)
        {
            return;
        }

        Debug.Log($"isMovingNow in {name} is being changed from {_isMovingNow} to {value}");
        _isMovingNow = value;
    }
}
agile marsh
#

only when there is the interact() function called

devout hare
#

Ok, next add Debug.Log($"{name} Start runs"); in the Start method

agile marsh
devout hare
#

so the script is on multiple objects

agile marsh
#

yeah

devout hare
#

Then it works as expected? Changing the variable in one object won't change it in others

#

nop the code in update still doesnt run

#

doesnt get past the condition if (isMovingNow)

#

i put back the debug.log in the update still output false after the interact() call

Did you have it print the name of the object?

oh no ...

its the wrong name

Hi, im trying to move froma compute buffer to a texture. When reading from the compute buffer at each index, i get this kind of distribution of values, but when doing from a texture they are more like this. What could be the reason?

image.png image.png
sage radish
tired fog
#

The original values are float from -170 to 720, to map them to the texture i get them to the range of 0 to 1, and then lerp it from -170 to 720

#

This is the generation of the value for the texture

float4 a = new float4(v.v0.position.y, v.v1.position.y,v.v2.position.y,v.v3.position.y);
a -= minMaxValue.x;
a /= (minMaxValue.y-minMaxValue.x);
#

basically the transformation to the range of 0 to 1

#

and then, from index to X and Y i do

#

originally, to calculate the right index i did

uint x = index%_TotalInstances;
uint y = floor(index/_TotalInstances);
float2 fractalIndex = uint2(x,y)/(float)_TotalInstances;
int2 floorIndex = (int2)floor(fractalIndex *(_Resolution));
int index = floorIndex.x+floorIndex.y*(_Resolution+1),
#

That was to map the index from the instances uv space, to the world uv and then multiply by the resoltion to get the specific index

#

now, I just use floordIndex as the UV directly

dusty wigeon
sage radish
#

So the data is two dimensional and that's why you want to move from compute buffer to Texture2D?

tired fog
#

the original data is a flattened two dimensional array

tired fog
tired fog
#

My idea was that maybe the range of values wasn't fully transfered for some reason, and lost precision, but I dont think im in such a big range or if I have any option to disable compression or something

#

Because the values on the texture are like floored (im only interested in Y values)

#

(but im not flooring anything on the final result)

dusty wigeon
tired fog
#

Yeah no, I just dont understand what do you want me to test

dusty wigeon
#

The conversion

tired fog
#

yeah, the pictures is what i get

sage radish
tired fog
#

RGBA32

sage radish
# tired fog RGBA32

That's a very small precision format, only 8 bits per channel, or 256 possible values.

tired fog
dusty wigeon
tired fog
sage radish
tired fog
#

i need the four channels because im storing the normal map on the other three channels

#

(and the same issue is there)

dusty wigeon
sage radish
tired fog
dusty wigeon
tired fog
#

The index goes from 0 to 255 on the compute buffer and the texture

#

Okay, im gonna test that, it has been always working. The first image is the intended result btw, i don't want them to be flattened following the terrain just yet

sage radish
#

You can also use the simpler RenderTextureFormat enum, with fewer options. RenderTextureFormat.ARGBFloat appears to be 32-bit floats per channel, signed and unnormalized.

#

But uses 4 times more memory than RGBA32.

tired fog
#

But im guessing that in any case, if I want more precision I will need more memory

sage radish
#

Of course

tired fog
#

Which format of Color do I need to use for RGBAFloat?

#

For RGBA32 i was using Color32

#

but using the same one it gives me the error of not enough data

sage radish
tired fog
#

Perfect! That does it!

#

Now i get the right range

image.png
sage radish
#

Are you okay with the memory though?

tired fog
#

Well, previously i was creating a compute buffer to store the same values, so the memory stays the same

#

I just save some time when sampling, altough I have to check now if there's any improvement and decide

#

But now I can save on instructions in general, since I can do bilinear sampling directly to the texture and not manually

ashen yoke
#

Hi Editor Script: I want to store a number of changes in a component on the Undo stack - ah I have to call Undo.RecordObject on every component changed? This is tedious, hmm

So, Im not sure what its happening. How does Bilinear Sampling work= If I have a texture that is 3x3

like this, and I sample at (.5,.5) shouldn't I have the same value with both, point sample and bilinear sampling?

In order to get around the common issues with standard singletons in Unity, I tried a hybrid approach of making a Monobehavior Manager a singleton, but rather than use a static instance for access elsewhere, it registers itself with a ServiceDirectory in it's awake. The Service Directory stores a references to the object, one for each interface it implements. Other scripts that want to use the singleton have to provide an interface to the ServiceDirectory and they get the object as that interface. I break up managers into multiple interfaces based on access level, i.e ITimeManager, ITimeEvents so that say things that just need read only access, don't get all the setters too. I've added extension methods for easily getting a services with as simple a command as GetService(out _audioManager). Does this seem like an effective pattern or overly complex?

cunning citrus
#

Does someone have used firebase anytime?... Cause i have one error message and it's being quite difficult for me to solve it

misty glade
#

This is close to the pattern I use, but I don't necessarily see why the managers need different interfaces?

I make my singleton a singleton, instantiate itself if it doesn't exist, put it in a DDOL parent in the loading scene, and then provide public static methods to everything inside it to reduce the boilerplate (like, everything that plays an audio clip just does AudioManager.PlayClip(clipEnum) instead of neeting to get the service directory, and ask it for an IAudioManager and then play the clip). I have lots of UI that .. just needs to play audio

cunning citrus
hoary plinth
# misty glade This is close to the pattern I use, but I don't necessarily see why the managers...

That is a reasonable take on it. I went that route as when I was doing my research the big counter to Singletons was that it makes all public parts of the manager available to anything that needs to use it anywhere. So a UI button could change the sound settings, or a label that is supposed to just get a read only value, could also set it. So the idea was to provide interfaces with limited access, to get it more in line with S.O.L.I.D design principles

misty glade
#

Yeah - I mean, you do what works best for you. Some people want to do the DI thing in Unity for singletons/services but I've found in history, I haven't ever (or very rarely) needed to swap out an "actual" implementation with a test implementation for the interface. I also just generally strive towards as little boilerplate as possible for doing things when I can.

I tend to hide things that .. need to be hidden... behind a well defined interface layer to the singleton itself.

image.png
#

So all the state and race conditions and stuff like that is handled by the singleton (versus each consumer of the API needing to be concerned with any of that)

#

(ie - note private int _idSequence)

#

In this game, lots of things can create new tiles .. things that have short lifetimes and the GameManager doesn't need to track them, but the id on those items does need to be unique, so I centralized it here, and basically anything can just use this to get the next id: public int NextIdSequence => _idSequence++;

im working with serialization and i left my pc on over night which i sometimes do, it went into standby mode. ive come back turned it on from sleep and run the code then im getting a system.io error 112 for some reason when running the code again today. literally nothing has changed since then. its only writing 8kb a time also and thats also still being written. ive checked two drives (one ssd one hdd), both had space and im still getting the error. its bizarre. ive also tried shutting the pc down to no avail

A quick google says your hard drive is full, or the disk is corrupt, or windows/temp is full

Is windows/temp full?

You might have a billion small files .. I'm not an expert but there's something about small files taking up all the space in the file allocation tables

post your code perhaps

Something else I saw says that the path might be too long

#

if you're writing that many 8kb i suspect you're putting them in nested folders with long path names

distant kernel
#

oh thats the thing, im only writing to a single file, the 8kb is a header thats written before

#

that writes fine initially, then the rest of the code which tries to divide up the byte[]'s and write their offset into the header

#

i did literally nothing and now it errors with the disk thing

misty glade
#

oh, you probably have a bug there then .. why are you writing directly to the header?

distant kernel

the header is just 8kb of integers before the serialization starts

as a lookup table

A lot of these patterns are actually implied as you develop it all, and you may not even realize that you would be implementing them. It's more that the concept of game design and optimization utilizes a lot of them.

Hey, Im trying to save a RenderTexture

        RenderTexture fog = player.FogOfWarTeam.currentFogTexture;
        Texture2D newTexture = new(fog.width, fog.height);
        AsyncGPUReadback.Request(fog, 0, (AsyncGPUReadbackRequest asyncAction) =>
        {
            newTexture.SetPixelData(asyncAction.GetData<byte>(), 0);
            newTexture.Apply();
        });

        byte[] textureData = newTexture.EncodeToPNG();

        System.IO.File.WriteAllBytes($"{_path}/fog.png", textureData);
#

and then im loading it like this

Graphics.Blit(fog.FogTexture, currentFogTexture);
#

but for some reason the loaded texture is just empty

sage radish
unborn current
#

ah, fair enough

sage radish
#

If you don't need it to be asynchronous, you can use Texture2D.ReadPixels instead.

unborn current
#

readpixels is too slow

sage radish
#

I wouldn't expect AsyncGPUReadback to finish any quicker.

#

It just doesn't block the main thread, but will likely take a bit longer than ReadPixels.

unborn current
#

what about Graphics.CopyTexture(fog, newTexture);

#

i guess movint it to GPU should be faster

sage radish
#

CopyTexture only copies within GPU memory. That won't let you write it to a file.

unborn current
#

so

var fog = player.FogOfWarTeam.currentFogTexture;
Texture2D newTexture = new(fog.width, fog.height);

Graphics.CopyTexture(fog, newTexture);

byte[] textureData = newTexture.EncodeToPNG();

System.IO.File.WriteAllBytes($"{_path}/fog.png", textureData);

wont work?

sage radish
#

It can't copy it right away because it hasn't finished rendering the frame you're asking it to copy.

#

So the delay will depend on how long it takes for the GPU to finish all the rendering work already added to the queue, which is related to your framerate.

unborn current
#

alright, so what can i do?

sage radish
# unborn current alright, so what can i do?

Are you sure you need the texture to be copied and written to a file as soon as your script tells it to, or is it okay if it takes ~0.1 seconds in the background, while your game continues running?

unborn current
#

it is okay if it takes less than a second

sage radish
#

You do not need to call Apply btw. That's just uploading CPU texture data to the GPU so it can be rendered on screen.

unborn current
#

alright, i will test it in a min

#

okay so the saved png is just empty

#

it weights like 190B

var fog = player.FogOfWarTeam.currentFogTexture;
Texture2D newTexture = new(fog.width, fog.height, fog.stencilFormat, );
#

but then what do i pass as a 4th argument?

#

its requesting some TextureCreationFlags

# unborn current its requesting some `TextureCreationFlags`

You can pass in the texture format of the Texture2D into AsyncGPUReadbackRequest to let it manage the automatic conversion.

Another option is to convert the NativeArray directly to PNG, without creating a Texture2D in between. You can use ImageConversion.EncodeNativeArrayToPNG for this. That might look like this:

        RenderTexture fog = player.FogOfWarTeam.currentFogTexture;
        AsyncGPUReadback.Request(fog, 0, (AsyncGPUReadbackRequest asyncAction) =>
        {
            NativeArray<byte> pngBytes = ImageConversion.EncodeNativeArrayToPNG(asyncAction.GetData<byte>(), fog.graphicsFormat, (uint)fog.width, (uint)fog.height);

            System.IO.File.WriteAllBytes($"{_path}/fog.png", pngBytes.ToArray());
        });

# unborn current thanks, it works :)

Cool. Keep in mind that EncodeNativeArrayToPNG is thread safe, but you're calling it on the main thread currently. So the game will lag while Unity is creating the PNG, but it might be quick enough to not be noticeable.

an HD image can take about 20ms to encode using the ImageConversion api, so you can't do it every frame on the main thread, unless you are okay with a 30 fps game

so the purpose is to make a little screenshot for a save?

the APIs for this stuff can be pretty cantankerous to use. you can try something like @unborn current

public async Task SaveAndQuit(RenderTexture fog, string path) {
  var wrotePng = new TaskCompletionSource<bool>();
  AsyncGPUReadback.Request(fog, 0, (AsyncGPUReadbackRequest asyncAction) =>
  {
    NativeArray<byte> pngBytes = ImageConversion.EncodeNativeArrayToPNG(asyncAction.GetData<byte>(), fog.graphicsFormat, (uint)fog.width, (uint)fog.height);
    System.IO.File.WriteAllBytes($"{path}/fog.png", pngBytes.ToArray());
    wrotePng.SetResult(true);
  });
  // this will allow you to wait for the thing to complete
  await wrotePng.Task;
  // now sequence the rest of the things you want to do
  // or you can do them all simultaneously
}

Is there any case where
commandBuffer.CopyTexture could possibly set the destination texture to be null...?

undone coral
#

right now you have something of the form

# 
void SaveAndQuitStep1() {
 AsyncGPUReadback.Request(..., req => {
  ...
  SaveAndQuitStep2();
 });
}

void SaveAndQuitStep2() {
 ...
}
#

of course that works

#

but it can be really chaotic

#

and this is code-advanced not code-chaotic

#

with what i am showing you, you can do

await Task.WhenAll(pngSavingTask, gameSavingTask, ...);
#

so that things can happen as fast as possible

#

when they do not need to be sequenced

#

OR you can reinvent async/await over and over again

scenic forge
#

Usually you would wrap a callback based API, in this case AsyncGPUReadback.Request which accepts a callback with result AsyncGPUReadbackRequest, into a method that simply returns a Task<AsyncGPUReadbackRequest>, without further processing.

#

That way you can do:

var result = await TheWrappedAsyncGPUReadbackRequest(fog, 0);
// continue rest of the processing with pngBytes and saving

And the wrapped method is reusable.

is it possible to create custom conditional compilations?

# dusty wigeon Depend on what you mean.

well, you know how you have things like
#if UNITY_EDITOR

well i was hoping to simply make a different conditional to try to access a get; set; variable only if another script happened to be referenced into an instance.
problem is, since it's a public variable, simply waiting on awake, doesn't really keep the variable from checking itself.

also i should probably point out the variables im referencing is using Photon Fusion, a netplay solution.

since it doesn't impact my testing or gameplay whenever im in my level tester, i can settle for not worrying about the error

oh really? 😮

cool then ^^

Any suggestions on improvements on this graphic buffer class? It's unfortunate but I need to update them every frame with new transform positions, so I'm basically clearing and recreating numerous structs up to the buffer's capacity every update. Because the buffer works off the exact index of copied data, recreating a list of values does not work since I need that stride in between populated indices, and sometimes I may have no data set in between each index.

#

The usage of the class is for particles, and because I may have some with different lifespans, I can't exactly create a queue or stack but I don't believe I could use those anyhow.

#

I don't think these buffers accept nullable types anyway so maybe I'm stuck always creating up to the capacity.

#

How crazy would it sound to have like maybe 100 of these buffers with 50+ structs each being created each frame going off?
