No

Show us where you start the world gen process

[dusky dust]

 public static HashSet<Vector2Int> simpleRandomWalk(Vector2Int startPos, int walkLength){
        HashSet<Vector2Int> path = new HashSet<Vector2Int>();
        path.Add(startPos);
        var previousPos  = startPos;

        for(int i = 0; i<walkLength;i++){
            var newPos = previousPos + Direction2D.GetRandomCardinalDirection();
            path.Add(newPos);
            previousPos = newPos;
        }
        return path;
    }

[shadow seal]

Where is that method called?

[dusky dust]

  protected HashSet<Vector2Int> runRandomWalk(){
        var currentPos = startPos;
        HashSet<Vector2Int> floorPositions = new HashSet<Vector2Int>();
        for(int i = 0; i < iterations; i++){
            var path = GenAlgorythem.simpleRandomWalk(currentPos, walkLength);
            floorPositions.UnionWith(path);
            if(startRandomlyEachIteration){
                currentPos = floorPositions.ElementAt(Random.Range(0, floorPositions.Count));
            }
        }
        return floorPositions;
    
    }

fixed, sent wrong code

[shadow seal]

And where is that one called?

Eventually, you'll show me the start like I asked

[dusky dust]

public void WorldGenerator(string type){
        if(type.Equals("Normal")){
            DungeonGen.instance.iterations = 400;
            DungeonGen.instance.walkLength = 400;
        }
        else if(type.Equals("Large")){
                 DungeonGen.instance.iterations = 500;
                 DungeonGen.instance.walkLength = 500;
        }
        WorldGenPanel.SetActive(false);
        DungeonGen.instance.runProcedualGen();
    
    
    }

this is called by pressing a button

[shadow seal]

Right so before you call runProceduralGen use Random.InitState()

[dusky dust]

ok

and the seed will be?

[shadow seal]

Just use 1 for now

[dusky dust]

and what do I put to save the tilemap>

[shadow seal]

We're getting to that

[dusky dust]

my bad

[shadow seal]

Now if you run the game you'll have some world generated

[dusky dust]

checking

it works.

now what?

[shadow seal]

So now remember what it looks like, stop and run it again

It should be the same when you press play again, because you still use 1 as the seed

[dusky dust]

it doesn't because i didn't change what uses the random function

here, I need to put something diffrent in the return?

[shadow seal]

No

Might be easier to change to using System.Random instead

[dusky dust]

ok

it doesnt work,

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public static class GenAlgorythem
{

public static HashSet<Vector2Int> simpleRandomWalk(Vector2Int startPos, int walkLength){
    HashSet<Vector2Int> path = new HashSet<Vector2Int>();
    path.Add(startPos);
    var previousPos  = startPos;

    for(int i = 0; i<walkLength;i++){
        var newPos = previousPos + Direction2D.GetRandomCardinalDirection();
        path.Add(newPos);
        previousPos = newPos;
    }
    return path;
}

}
public static class Direction2D{

public static List<Vector2Int> cardinalDirectionsList = new List<Vector2Int>(){
    new Vector2Int(0,1),//UP
    new Vector2Int(1,0),//RIGHT
    new Vector2Int(0,-1),//DOWN
    new Vector2Int(-1,0)//LEFT
};
public static Vector2Int GetRandomCardinalDirection(){


    return cardinalDirectionsList[System.Random];
}

}

[shadow seal]

Yeah because you can't just go changing it like that

I'll make a quick example

[dusky dust]

thanks

[shadow seal]

https://pastebin.com/SrSDHuYh

Oops, didn't mean to leave Awake in

And in your case, Start would be substituted for your button press method

There, made it more relevant to your world gen too

[dusky dust]

the problem is i can't make a var in it for some reason

[shadow seal]

Hm?

[dusky dust]

in the direction function i need to put something, i dont understand what

[shadow seal]

I have no idea what you're asking

[dusky dust]

here in the []

[shadow seal]

Have you looked at the newer example

[dusky dust]

ye, didn't help

never mind, fixed

thank you very much

@shadow seal Would you like to get credit in the game on the help?

[shadow seal]

I don't put my name on anything, means I can't be blamed

But yeah if you get it working with the seed, you can literally just save that int to a file and use it to recreate the same dungeon each time

[jolly token]

You might be in trouble if something changed in generation process when you updated the game

[wintry wind]

Hi, I'm looking to build a system that allows creating a "script" for each level. Here's an example of what I mean by a script for the level:

• Travel to X (marker on the radar)
• When arrive X, spawn a group of enemies
• After half of the group destroyed, play a sound and increase a variable (intensity) in another system (it needs to be flexible)
• When group destroyed, travel to Y (another marker)
  I'm curious about what kind of solutions anyone here has used in the past. Was thinking of something node based.

[compact ingot]

That’s generally what you do in gameplay scripting. So basically write a c# script that does it. You could make a visual tool for it if you want to codify the vocabulary of what you want to allow that a designer could then use. Assets like FlowCanvas work well for that. Or if the options are more constrained/similar to each other, simply make a config inspector.

[wintry wind]

got it, so each level would get it's own script, right?

[compact ingot]

Yes, Could be, but depends on how many reusable components it all has.

it’s always a mix of specialized scripts, some configuration on them and reusable components

[wintry wind]

👍

[stuck onyx]

For what i've been testing Time.realtimeSinceStartup it keeps working while the app is in background, so it seems possible to calculate the time the user has spent out of the app accurately by using the OnApplicationPause event , is anybody using it for this purpose? do you find any problem on using it for this or is there anything i should know?

[glass narwhal]

Hello is there a way to upload a texture to a http server usint WWW?

Can you send me an example? should i encode the texture to bytes or how?

[sly grove]

Www is old and deprecated

Use UnityWebRequest

Also it depends on how your server is expecting the request to be formatted

Without knowing that we can't answer

[glass narwhal]

Okay i changed to UnityWebrequest, i have a smple python http server accepting a png or jpg

i just dont know how to send a post from unit containing the texture

[muted root]

Hi, is it possible to transform a grayscale bump map to a normal map at runtime?

[upbeat path]

to create your form https://docs.unity3d.com/ScriptReference/WWWForm.html
to post it https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequest.Post.html

[muted root]

Basically, I'd need to do what the Unity texture Importer do when using a greyscale texture.

At the moment, I'm using this code found online but it's not working at all.

`
Texture2D normal = new(tex.width, tex.height, TextureFormat.ARGB32, false);
for (int x = 1; x < tex.width - 1; x++)
for (int y = 1; y < tex.height - 1; y++)
{
//using Sobel operator
float tl, t, tr, l, right, bl, bot, br;
tl = Intensity(tex.GetPixel(x - 1, y - 1));
t = Intensity(tex.GetPixel(x - 1, y));
tr = Intensity(tex.GetPixel(x - 1, y + 1));
right = Intensity(tex.GetPixel(x, y + 1));
br = Intensity(tex.GetPixel(x + 1, y + 1));
bot = Intensity(tex.GetPixel(x + 1, y));
bl = Intensity(tex.GetPixel(x + 1, y - 1));
l = Intensity(tex.GetPixel(x, y - 1));

                //Sobel filter
                float dX = (tr + 2.0f * right + br) - (tl + 2.0f * l + bl);
                float dY = (bl + 2.0f * bot + br) - (tl + 2.0f * t + tr);
                float dZ = 1.0f;

                Vector3 vc = new(bumpStrength * dX, bumpStrength * dY, dZ);
                vc.Normalize();

                normal.SetPixel(x, y, new Color(0.5f + 0.5f * vc.x, 0.5f + 0.5f * vc.y, 0.5f + 0.5f * vc.z, 0.0f));
            }
        normal.Apply();`

The resulting image is still grey with a visible 1px border because the loop are starting from 1 and finish at less than 1 the max.

[undone coral]

why?

you can read the code for height to normal conversion out of the shader graph source

but it's better to create the shader graph shader that accepts the height map in grayscale as an input

its bonkers to manipulate the textures in C#

[undone coral]

yes, punch into google "file upload unitywebrequest"

it sounds like you want to use a transform and no rigidbody, you've been at this for a while. you want specific behavior, too specific where you're just working around all the physics simulation rigidbody does for you

[regal olive]

nah i need it to collie with asteroids

so yea

[undone coral]

i mean you can set it to a kinematic rigidbody

and don't touch anything on it

[normal lagoon]

why does my animation not detect physics?!?i have the animate physics option on. basically its a sword swinging animation, and the enemy has a hit detection script which should launch it way back once hit with a gameobject tagged with "Sword", so why doesn't it? 99% of the time it doesnt work. works if i walk into the enemy without animation, tho.

[sly grove]

how does your hit detection script work

[normal lagoon]

it has OnTriggerEnter(The Sword is a trigger) and basically it says '"if(other.gameObject.tag == "Sword)
{
addrelativeforce
}

[regal olive]

fr?

[normal lagoon]

it works if the sword collides with the enemy holding the script without using the slash animation (ex. if i walk into them with the sword) but for some reason doesn't work with animation

[regal olive]

its gonna work perfectly with colliders?

[sly grove]

probably better off using animation events and direct physics queries like overlapbox etc...

[normal lagoon]

oh thats something i haven't gotten into yet. but if it would help, im willing to learn!

[undone coral]

yes

in the sense that it will impart momentum on them

but it will not receive momentum from them

[coarse valve]

what would be the best way to reduce the amount of characters in a text file to reduce file size, saving the same info but with less characters?

[undone coral]

in unity textassets are already compressed by the LZ / LZHC compression options in your build settings

so the best thing is to do nothing

[coarse valve]

I meant for the save file I create

for the local save

[undone coral]

you can import ionic zip and read/write it with a compressed stream

[coarse valve]

thanks, I'll look into that

and for the cloud save I have to upload to google play? I think that can only be a simple txt, a string

[undone coral]

cloud save
hmmm
I have to upload to google play

hmm...

what are you trying to do?

[undone coral]

what is your game?

and what are you trying to save?

[coarse valve]

an incremental for mobile, the problem is the max size of the cloud save is 3mb and in the worst case the save im making can have 280mb, so I need to reduce it a lot

[undone coral]

an incremental
?

in the worst case the save im making can have 280mb
what is the game?

[coarse valve]

an idle/incremental/clicker genre

[undone coral]

you don't need a 280MB save file

what are you saving?

oh boy

lol

"so in order to encode a number that's so and so big..."

"and the positions and the numbers of every factory"

"my game is a very authentic simulation of the subatomic forces emerging into the entire coin factory"

"hence every particle gets its charge, spin and position - classical, of course - recorded along with its hamiltonian"

[upbeat path]

https://docs.microsoft.com/en-us/dotnet/api/system.io.compression.gzipstream?view=net-6.0

[undone coral]

yeah but if it's 280MB it's going to take like 30s to compress

his game will just freeze

[coarse valve]

oh perfect

[undone coral]

you don't want to fix the problem that is your 280MB save file?

it's totally intractable what you are doing

[upbeat path]

Not my problem, I answered the question he asked, why he asked it or needs it is another question

[undone coral]

lol

[coarse valve]

yeah, im not looking for a zip/compressor, I just want write less characters

[undone coral]

well

you gotta say what you're saving

in order to "write less characters"

[upbeat path]

So, basically you want to develop your own IL code system

[coarse valve]

the information of buildings in a planet, each planet has max 400 buildings, each with an id, a level, and the time to finish building the next level
so for example it can be, 22299992235959 (the first 3 digits being the id, the next 4 the level, the next 1 days, the next 2 hours, the next 2 mins, and the last 2 secs)

so its sth like 22299992235959-22299992235959-22299992235959...-22299992235959

[undone coral]

okay

[coarse valve]

worst case is the all planets are available and all planets have all 400 buildings in construction, and there are 38.880 planets,

[sly grove]

I assume this is a procedurally generated game?

Only save what the player has actually changed

[upbeat path]

first thing do not code text, code binary tjhat will save you a lot of space. Second thing do not save times as days/hours/minutes/seconds save as Ticks, that will save you even more space

[undone coral]

hmm

well even in binary and with ticks it's 400 * 38880 * (2+2+4) bytes = 124,416,000

[coarse valve]

this are the things I needed to hear

[undone coral]

yes, because you finally answered my question

[coarse valve]

but maybe I can store it in base 36 or bigger and reduce the chars

[undone coral]

i think you have to do what PraetorBlue said

i'm pretty sure you only have to store the tick when actions were taken and you can recreate the state of the game analytically

is a player ever going to be able to create 38,880 planets ever?

hard to know without learning a lot of detail in your game

[upbeat path]

you can take the 124,416,000 and zip it, that will probably bring it down to < 100k

[undone coral]

that is true

you should do it with a binary format though

it's very easy to do

good luck @coarse valve !

[coarse valve]

no, the player would at most control 10-20, more would be tedious, the others would be managed by an npc manager

ok, I'll look into these methods, thanks everyone

[torn basalt]

Hey, what does it mean if an entire class is greyed out.? I imported a package from an old project and its yelling about a class not existing. I opened the offending class and its completely greyed out.

[undone coral]

that's an interesting problem

maybe wrong scripting defines?

[torn basalt]

figured that so that was the first thing I checked. Odd

[torn basalt]

regenerated the project files fixed it.

[valid flame]

Can someone help me install Rosyln Analyzers? I'm having issues getting any messages to show in the console.
https://docs.unity3d.com/Manual/roslyn-analyzers.html

I can see these analyzers in the references

However all of the rules are set to 'none' and I can't change the rules

Its my understanding that there's supposed to be a configuration file I can use somewhere but its never mentioned WHERE that is

[jolly token]

I think it's more of Roslynator setting, you can put .editorconfig under your project root I believe.

I tried to do the same thing but including Roslynator inside of Assets folder ate up Unity performance.

I end up just including it somewhere else and write omnisharp.json (I'm using VSCode)

[valid flame]

.editorconfig is already included by default at the project root?

[jolly token]

In your project?

[valid flame]

Unless you mean the assets folder

[jolly token]

I meant project root.

[valid flame]

then yeah .editorconfig is already there

I'm using visual studio though

[jolly token]

You can set rule's severity from there then

[valid flame]

Where, exactly?

Currently I only have Microsoft.Unity.Analyzers

[jolly token]

By editing .editorconfig

[*.cs]
# Convert 'if' to 'return' statement
dotnet_diagnostic.RCS1073.severity = none
# Mark local variable as const
dotnet_diagnostic.RCS1118.severity = silent

That's part of my setting

[valid flame]

So i have add every single rule manually? That can't be correct

Especially when I know the way its SUPPOSED TO work is that as soon as I drop the analyzer dlls into the project, it should begin working immediately after I label them and turn off the required boxes

[jolly token]

Yes default setting for rules aren't suppose to be none

[valid flame]

Oh, yeah there it goes

Why does it default to [true:suggestion].. so weird

[jolly token]

https://docs.microsoft.com/en-us/visualstudio/code-quality/use-roslyn-analyzers?view=vs-2022
It says about setting severity by category, or for all

You should check your settings to see if anything forcing the severity to none

[valid flame]

I have no idea but it was doing that, I was completely unable to change the severity of any rules

I'd change it to something like warning or suggestion and it'd instantly revert back to none without any message or feedback

[jolly token]

But you can see dlls refrenced from the csproject that unity generated, I think unity side of setting is done

[surreal vessel]

how do games implement something like a* pathfinding? im not asking about the actual algorithm, rather how they optimise it because i doubt they run it each frame for each enemy

[undone coral]

really depends on the game

can you name a specific one?

[valid flame]

Not every frame, but you could probably do every frame if the performance isn't too much of an issue

Usually re-calculating the path every frame would be pretty terrible though yeah

[surreal vessel]

not anything specific just maybe theres some trick to like cache parts of the path or something

[jolly token]

You could set update interval or max distance to search

[undone coral]

well... try to answer my question

it really depends a lot on the game

starcraft 2 and league of legends, for example, uses something very very similar to unity's navmesh pathfinding

where ground units that are attacking, and are therefore stationary, become obstacles

and "turn right to avoid" is the avoidance approach

there are some details about not leaking unseen information because they're multiplayer games

so if you're talking about those games - games with RTS approaches from that era - that's the behavior, it's navmesh

navmesh is itself a copy of starcraft 2 (warcraft 3) pathfinding behavior

on purpose

they even have the same names for the fields for navmesh agents as starcraft has for its unit movement parameters, on purpose

calculating the path in navmesh is very fast. it can be run every frame, for the hundreds of units there are

[surreal vessel]

ah interesting

[undone coral]

the servers that execute the game logic aren't constrained in the same way a unity client game running on a phone is

[surreal vessel]

im using tilemaps, there can be obstacles but they have circle hitboxes so the enemies dont need to worry about that

[undone coral]

because pathfinding is so critical to behavior in those games i don't think they take many shortcuts

[surreal vessel]

but really the only obstacles are walls

i just want enemies to be able to find a way to get to a different room if theres a wall inbetween

but a path around that wall

i could do the check every second and stagger it for the enemies so trhere isnt a lagspike each time

but i thought maybe theres some smart optimisation with the algorithm

maybe not a* maybe even different ones

i guess navmesh works by like simplifying the map into triangles, so then you can just go through the triangles as a whole rather than each point in space?

[undone coral]

what is your game? @surreal vessel

[surreal vessel]

roguelike dungeon crawler type thing

topdown view

[undone coral]

is it tile based movement?

[surreal vessel]

nah

butt he maps are tile based

[undone coral]

okay

well you can figure out how to build a navmesh

for a tilemap world

and query it for gameplay purposes

even if you don't use it for navigation

[surreal vessel]

yeah its a bit awkward for 2d because unity forces the nabmesh plane to be in xz orientation

[undone coral]

i think you can figure it out with the navmesh component workflow

[surreal vessel]

but i saw a package that calculates it and does some stuff to make unitys navmesh work

for 2d xy games

[surreal vessel]

eh i use colliders for stuff

maybe i could do like a raycast test to see if theres a solid wall in the way

if not then just aim in direction of player and go

[undone coral]

you should use navmesh since it solves your problem correctly

[surreal vessel]

yeah but its a bit inconvenient with the way i have to use it

ill try some of the stuff i said and if that doesnt do it then ill do navmesh

[severe trail]

figured it'd be easy to find a recipe, but haven't located onew

use case is creating a clone, changing the vertice positions and boneweights, and saving a copy

[muted root]

Creating a custom shader is too time consuming at the moment with my skills so I've been sticking with the hdrp / lit layered. If I wanted to reproduce the capabilities if the lit layered, I'd need dozens of nodes all interacting with each other to make it work which is too complex with my current skills. So I've been searching on Google for a way to transform bumps to normal map so that the process is automatic. I luckily found a solution after tinkering for hours and I'm able to generate normal maps from bump map at runtime, similar to the Unity Texture importer and save them to a cache folder to reuse them easily. One important thing I learned about using normal maps at runtime is that when you create the texture, you need to set the fourth parameter of the constructor to true to enable the linear property. It seems like normal maps need that to work properly. In the end, most of my ideas and layered clothing system is working except some problem with handling transparency, both in opaque and transparent mode. For example, using lit layered, if you load an opaque texture and apply a PNG containing some semi transparent pixel in layer 1, they will render as fully opaque which I think is a bug. I've opened a report but no news so far.

Same with transparent mode, if you load a first horizontal gradient to transparent in main layer then a vertical gradient to transparent in layer 1, a visible vertical transparent stripe in the middle of the resulting texture which should be a bug too, related I guess?

[undone coral]

you can use decals though

we discussed this

LayeredLit is meant for car paint

there's also this https://assetstore.unity.com/packages/tools/particles-effects/uvpaint-skinned-mesh-decal-system-61022

which is pretty much what you're trying to make

[wise jay]

hi, i couldn't get answer on #archived-code-general so i'll ask here.
What might be a reason that my TextMeshPro is not updating at Runtime? It is updated if I exit playmode and renter it. Found some answers for my problem but none of them worked.

I know it's ugly but trying to make it work first, and SetText() doen't work too.

    void SetDetailsOfTask(Task task)
    {
        detailOfTaskGO.SetActive(false);

        clientText.enableAutoSizing = false;
        dogText.enableAutoSizing = false;
        taskDetailsText.enableAutoSizing = false;

        clientText.text = $"Client: {task.TaskClient.FirstName} {task.TaskClient.Surname}";
        //clientText.text = $"Client: {task.TaskClient.FirstName} {task.TaskClient.Surname}";

        
        dogText.text = $"Dog: {task.TaskDog.DogName}, agressivness: {(int)task.TaskDog.DogAgressivness}, LTL: {(int)task.TaskDog.DogListeningToLeader}, SFP: {(int)task.TaskDog.DogSympathyForPlayer}";
        //dogText.text = $"Dog: {task.TaskDog.DogName}, agressivness: {task.TaskDog.DogAgressivness}, LTL: {task.TaskDog.DogListeningToLeader}, SFP: {task.TaskDog.DogSympathyForPlayer}";

        
        taskDetailsText.text = $"Task details: Place: {task.TaskAddress.name} at {task.TaskAddress.transform.position}, for: ${task.TaskPrice}";
        //taskDetailsText.text = $"Task details: Place: {task.TaskAddress.name} at {task.TaskAddress.transform.position}, for: ${task.TaskPrice}";

        clientText.enableAutoSizing = true;
        dogText.enableAutoSizing = true;
        taskDetailsText.enableAutoSizing = true;

        clientText.ForceMeshUpdate();
        dogText.ForceMeshUpdate();
        taskDetailsText.ForceMeshUpdate();

        detailOfTaskGO.SetActive(true);
        

        Canvas.ForceUpdateCanvases();
    }

[undone coral]

media store?

[undone coral]

are you using URP? what are the aura postprocessing shaders?

[undone coral]

textmesh pro updates at runtime. you have some other issue

[wise jay]

strange thing is that, when i exit playmode, those textes updates but in editor mode.
Issue might be cuz of prefabs?

it works sth like that, i hope it's at least a little understandable XD

code :

            if (btn == button)
            {
                lastChosenIndex = index;
                Debug.Log($"Match: {btn.GetInstanceID()} == {button.GetInstanceID()}");

                Debug.Log("\n");
                TaskManager.Instance.ActiveTask = TaskGenerator.Instance.TasksList[index];

                break;

            }
            index++;


        }
        SetDetailsOfTask(TaskManager.Instance.ActiveTask);

        TaskManager.Instance.PrintActiveTask();
    }

well it works kind of, objects and indexes are correct, issue is with that text update

and i strated thinking if its something about that ui manager is prefab (and uimanager is Parent for all UIs)

i tried to make static string variables to store proper data and then assign it to text objs but result is same

 void SetDetailsOfTask(Task task)
    {
 

        sClientText = $"Client: {task.TaskClient.FirstName} {task.TaskClient.Surname}";
        //clientText.text = $"Client: {task.TaskClient.FirstName} {task.TaskClient.Surname}";


       sDogText= $"Dog: {task.TaskDog.DogName}, agressivness: {(int)task.TaskDog.DogAgressivness}, LTL: {(int)task.TaskDog.DogListeningToLeader}, SFP: {(int)task.TaskDog.DogSympathyForPlayer}";
        //dogText.text = $"Dog: {task.TaskDog.DogName}, agressivness: {task.TaskDog.DogAgressivness}, LTL: {task.TaskDog.DogListeningToLeader}, SFP: {task.TaskDog.DogSympathyForPlayer}";


       sTasksDetailsText = $"Task details: Place: {task.TaskAddress.name} at {task.TaskAddress.transform.position}, for: ${task.TaskPrice}";
        //taskDetailsText.text = $"Task details: Place: {task.TaskAddress.name} at {task.TaskAddress.transform.position}, for: ${task.TaskPrice}";

        UpdateTextObjects(sClientText, sDogText, sTasksDetailsText);

    }

    void UpdateTextObjects(string clientT, string dogT, string taskDetailsT)
    {
        clientText.text = clientT;
        dogText.text = dogT;
        taskDetailsText.text = taskDetailsT;

    }

Are you referencing the prefab from script by any chance not the actual object in the scene?

Sounds like you're editing prefab, not the scene object

[wise jay]

well, tbh im not sure. cuz when i created prefab which is creating task summarys i can only attach prefab from project explorer, not hierachy (Scene)

[river otter]

prefabs are in project explorer, if you drag from hierarchy you're just referencing an object in the scene

that's not a prefab

though you can still duplicate it with Instantiate

[wise jay]

yeah right, i mean that

[jolly token]

So you are referencing UIManager prefab from that prefab? That is causing issue

[river otter]

you say your problem is your text is only updating on exit and rentry? does sound like you might be accidentally editing the prefab

those changes survive play mode exit in my experience

[jolly token]

You need either

• Make your Task-managing prefab as scene object and reference the UIManager scene object
• Dynamically find UIManager game object from scene (With something like GameObject.Find)

[wise jay]

as you can see it's updating but not in runtime

[river otter]

your code blocks look ok to me, make sure that code is being run on a scene object, not on the prefab itself

not sure if that code is on a prefab itself or not from what you said

[wise jay]

yup. it is

[jolly token]

So the thing is, while runtime your edit to the prefab does not apply to your scene object

[river otter]

You can put a Debug.Log in CreateUITask to check the value of this.gameObject.scene I think

prefabs have no scene

or gameObject.root (or it's on transform or something)

as the root of the prefab will be different from the scene root

just to be sure you're not accidentally modifying the prefab itself by running code on it

[wise jay]

it references are like this

[river otter]

yeah when you drag from the project hierarchy to an event handler it's going to be running code on the prefab

same with dragging the prefab to the argument

not sure why you can't drag the actual object to the event handler

[jolly token]

He can't because he is trying to reference it from the other prefab

You should work that part on the scene not the prefab

[river otter]

ah

yeah the object and the button must exist in the same hierarchy

to assign in the inspector

otherwise you have to do it in code

buttonReference.onClick.addListener(functionReference)

[wise jay]

ok, so when i have TaskCompUI prefab which has button in it i'll have to add button via code after instantiate()?

[jolly token]

It's either you do it with code or you put your TaskCompUI to scene. read this

[river otter]

if I understand you want the button in the prefab to call back to the parent object

generally I assign the event handler with code for that sort of thing

if you have only one button you can do taskUI.GetComponentInChild<Button>().onClick.addListener(() => this.SetActiveTask(taskUI));

something like that

[jolly token]

If you're instantiating TaskCompUI dynamically then you gotta reference scene object of UIManager dynamically yes. 😄

[wise jay]

thx guys for help, gonna try it now, ill let know if it works

[echo wigeon]

I fixed it by building my project on a different hard drive 🤟

[wise jay]

THIS WORKS MANY THANKSSS!!! ❤️

well i remember i figured out someday differences between references hierarchy and project but that thing when i couldnt reference to UIManager form scene made me stupid

many thanks again

[river otter]

is possible to +rep someone on this server?

[muted root]

Decals won't work because the whole texture needs to wrap around the cloth, it's not a decal. Car paint it actually exactly what I want, put an initial layer of color on the cloth, add another layer of lines here and there, and another logo in front or back. This is working exactly like that.

For example this one: it's a PNG containing the outline I'll want to show on my tank top. So I put a first layer of fuzzy background then I apply this outline over the background. I can color each layer individually as well as put whatever smoothness and metallic as I want.

Can decals wrap around the whole cloth too and use on texture like this?

[novel plinth]

Multi textures shader is like easy enough to make.. youtube is your best bet here

[muted root]

Maybe for an expert but I don't know how to code shader and shader graph is quite complicated to learn for beginners. I gave it a shot but couldn't even get 2 transparent layers to merge together properly

The hdrp lit layered does exactly what I need except for not handling semi transparency which is weird.

Because if lit layered is actually used for car paint, shouldn't it be able to handle semi transparent colors?

[novel plinth]

No code, pure graphs.. trust me, not as hard...

[muted root]

Well, take a look at this for example

And here is the result

the result should be what we see in the maximum node actually. I've tried all nodes but nothing works.

If I can't even get a simple transparency merge, I don't think there's much point in trying harder lol 😄

[plucky laurel]

it seems to work

it does exactly what you want, its just that you plugged the color output

[muted root]

Well, if I unplug the color it works, but the end game would be to merge cloth textures which do have color AND transparency

I was using simple white gradient to get the basics down

[plucky laurel]

i dont understand where the problem is because it seems rather trivial what am i missing?

[humble onyx]

You probably want to use a lerp instead of blend

The alpha of the overlay should say what part should be the overlay the rest is the layer below

[plucky laurel]

direct lerp chain

you are tempting me to launch shader editor 😄

[muted root]

loool

[plucky laurel]

cant im sorry, something like combine alphas, feed into lerp, add next, feed into lerp, repeat

[muted root]

Well, I am a beginner I said so I only have basic notions.

[plucky laurel]

or no need to combine actually

[muted root]

What is "add next" ?

[plucky laurel]

add 2 colors, 1 lerp node, 1 alpha node

[muted root]

Like this ?

[plucky laurel]

no unplug the alpha sources from lerp

just make 2 color nodes

plug them in A, B of the lerp

[muted root]

Where do the textures go then?

[plucky laurel]

color nodes == textures

[muted root]

Ah lol

[plucky laurel]

same thing youre just using simple scenario

[plucky laurel]

nah

[muted root]

Well, as you said, it might be easier with a tutorial on youtube, I'll stop wasting your time sorry.

But overall, the lit layered does exactly what I need. But is it normal for it to not handle semi transparency or even merge transparency properly??

[plucky laurel]

for merging transparency you just chain max them i guess like you did

btw wrong channel

[muted root]

Wait, it means you need a mask for each layer you want to merge?

[plucky laurel]

ofc

[muted root]

Does the lerp work with semi transparency ?

If your star is blurry, will it be blurry at the end too?

I'll give it a shot

[plucky laurel]

yes

lerp is done per pixel

its same thing as Mathf.Lerp

[muted root]

It's just a shame the lit layered doesn't do it properly itself, that would have been perfect. I don't know why it can't; merge such simple stuff properly.

[plucky laurel]

what that toggle "use opacity map as.."

[muted root]

It's to use the alpha of this texture as transparency if I got it properly

Without this, the layer is opaque

Hm, not opaque, the background just completely disappear actually

[plucky laurel]

you should read docs and tinker with it some more

i am pretty sure you can find a way to make it do it

[muted root]

Ok, I'll look into it more but the last few hours I spent on this didn't give me any clue at a solution for this simple case ;'(

[plucky laurel]

you can always fall back to custom shader, but it would be good to rely on something standartized.. or would it

with your shader you have the control, so yeah

[muted root]

That was my mindset, always go the easy way because my project is already complex enough as it is.

But having control over the shader has its appeal indeed

[muted root]

Anyway, thanks again for you time and sorry for posting all that on the wrong forum :x

[wanton lagoon]

Hi guys I am new here so not sure if this is considered advanced but I am trying to multithread Sabastian Lague's Boids code https://www.youtube.com/watch?v=bqtqltqcQhw&t=162s. The problem is none of the boids are moving when I run the code. I am not sure if I am passing the correct transform access array either but I have attached the snip for both.

[livid kraken]

You can spend 50 more hours and still dont have anything. Like you have been told before layered lit is not ment for what you want to do.

[livid kraken]

you might want to actually fill the transforms array with data https://docs.unity3d.com/ScriptReference/Jobs.TransformAccessArray.SetTransforms.html

right now its empty

[wanton lagoon]

so at every frame I provide it with the Boids transforms?

I thought that won't be too efficient. Sorry not too sure how unity works under the hood

[livid kraken]

I'm pretty sure it works like a pointer

so you dont need to set it every frame

just once for all boids

then again having your boids are gameObjects is inefficient by definition

[wanton lagoon]

yes I am not using ECS just Jobs and burst compiler, thanks for the help though I think I get it now.

[livid kraken]

you can still look into instanced indirect rendering and dont use GO at all

that will save you a ton of overhead

[lime marsh]

I don't know which channel to put this in. Might be advanced. Might be beginner I don't know 😛
I don't know how to describe so I drew it (P.S not an artist)
So that small blackline in the middle would bounce between both sides and you have to click to get it as close to the (Green) as possible to score high points, yellow isn't perfect but it is okay and outside of that is a no go. I am just curious how I would do something like that?

https://cdn.discordapp.com/attachments/937046181769543760/1010904191222423572/unknown.png

[somber swift]

Break it into smaller parts, make it bounce between sides (take a look at sine wave or animation curves) and then make a function that gives the distance from the middle (required to calculate the score). You can also maybe move the colored areas randomly so its not always in the middle (as in the image)

[lime marsh]

What I was thinking was to use a Slider but I am not too sure where to start 😅

But I never thought about the Sine wave to make it bounce back and forth

[silk sable]

Thats not the best idea, a lot of overhead for something that is simple.
Just make a ui element/ sprite go back and forth by offsetting it's x position to the sine of time

and from there build the functionality

If you have any further questions probably dont ask it there as it's more #💻┃code-beginner imo

[misty glade]

I have a dialog box that does a fair bit of Instantiate() and it burps - takes about 250ms to initialize. Digging into the profiler hasn't really uncovered anything I can optimize about the initializer. Is there a way I can async initialize this stuff without causing a framerate burp?

I don't know if one 250ms burp is worth putting a loading screen in and putting the load stuff in a coroutine.. I'm more interested in keeping the framerate smoothish

[wise fossil]

Is there an advanced game dev here that know perfectly how to use UI buttons please ?

[jolly token]

Nobody is perfect but you can try throwing question

[wise fossil]

Well I need to call an Input with a UI button

First I have a button that have a Trigger Down on it, related to my player script and to a function called Movement

in that function I have semthing like this :

if (Input.GetKeyDown(KeyCode.D))
{
//my code
}

and I would like something like this :

if (Input.GetKeyDown(KeyCode.D)  ||  SomethingWorkingLikeAnInputDownWorkingWithMyButton)
{
//my code
}```

[misty glade]

#💻┃code-beginner or #archived-code-general

[wise fossil]

no one knew there !

[misty glade]

I'm absolutely sure that's not true, but no one may have answered right away.. Wait a while, ask again, rephrase your question, etc.

To answer your question, call a method from both entry points:

if (Input.GetKeyDown(KeyCode.D))
{
  DoMovement();
}

...
public void OnButtonClicked()
{
  DoMovement();
}

...

public void DoMovement()
{
// Your code
}

[wise fossil]

Yes I would like to create an Input

[wise fossil]

Hum that could work

maybe a bit long

but I'll try

But I m sure it s possible to create something alike an Input

Input as a code itself, but I don t know where to find it

[slow mica]

How do you correctly setup a Unity Project with GitHub?
I have a Project and have synced all .meta Files with it.
But still some things like Sorting Layers are not working, and if you rename any Asset GitHub thinks it got deleted.
So... how do I set this up correctly?

P.S.
I work with JetBrains Rider

[misty glade]

You'll need a "correct" .gitignore file. This one looks fine: https://github.com/github/gitignore/blob/main/Unity.gitignore

[rugged radish]

that's how git works, rename is a delete + add usually

[misty glade]

No, that's the wrong approach. You collect your input and route it to a method that does the work. Tying logic or code to the input means having two ways of doing something means you have to write the same code twice, which is wrong. Google "DRY" (don't repeat yourself)

[wise fossil]

I m testing your method, I will see if it works !

Alelhuia it is WORKING

[wise fossil]

well that wasn t really what I wanted to create, I wanting to call a function with my button that put a boolean true for only one frame

like an Input.GetKeyDown does

[misty glade]

then... do that? 😛

private bool hasPushedThisFrame = false;
...
public void OnClickHandler()
{
  hasPushedThisFrame = true;
}

...

if (Input.GetKeyDown(KeyCode.D) || hasPushedThisFrame)
{
  hasPushedThisFrame = false; 
  ... do stuff ...
}

[wise fossil]

yes I thought about this

[misty glade]

But just so you know, this code 👆 sucks for a number of reasons, but again, this is a #💻┃code-beginner question, not for this channel so the reasons why might be .. difficult to grok for the moment

[wise fossil]

But someone said it was not good at all

[misty glade]

probably me, yes

it is garbage

[wise fossil]

haha not this time

[misty glade]

but you're having an XY problem at the moment

[wise fossil]

but yeah I know it sucks

[misty glade]

You think you know what the solution is so you ask how to implement the solution (which I've shown you in the code above) but that's not really how you should accomplish what you're trying to accomplish, which is how do I get code to do some movement thing when a user presses a button OR presses a key

[wise fossil]

but doing separated methods works well

[misty glade]

👆 read this like 16 times and google every word in that sentence until you understand how to do it because this is the right answer

[wise fossil]

Sorry I do that all the time 😂

[wise fossil]

I first need to translate it 🤪

[misty glade]

private void DoMovement() { .. }
public static event Action MovementRequestedEvent;
private void Awake()
{
  MovementRequestedEvent += DoMovement;
}
private void OnDestroy()
{
  MovementRequestedEvent -= DoMovement;
}
public void OnClicked()
{
  MovementRequestedEvent?.Invoke();
}
public void OnMovementKeyPressedHandler()
{
  MovementRequestedEvent?.Invoke();
}

there's the rough stub for you

google everything in it until you understand it

[wise fossil]

oh

I m gonna do that

(google it)

[misty glade]

Just to be clear, this is the XY problem. What you are asking here is how to implement a solution, but the real question is simpler: how do I make a keypress and a button do the same thing

https://xyproblem.info/

[wise fossil]

Yes that is exactly the problem

are u a teacher ?

[wise fossil]

but I tried to tell that is other discords servers but no one knew

well okay they knew... 😅

[hot gale]

Quick question, coz I'm having a discussion with a few maths and science buddies:

We have a flower. The flower has a 10% chance of being Blue, 10% chance of being Red and 80% of being White.

What is the best way of programming this?

[wise fossil]

Use Python 😉

[hot gale]

For a Unity Simulator that simulates genetics?

Don't know about that one chief.

[jolly token]

Use Random class?

[hot gale]

Some of the friends seem to think that simply loading an array with choices (B,R,W,W,W,W,W,W,W,W) and then picking one of the ten would be better.

And the others think that using percentages (Random.Range(0,1) <= .1f etc) would be best.

[jolly token]

Why? What if the chance is like 12%?

Using Random would be much generic solution

[hot gale]

Then I assume they'd want to put in 100 options and have 12 of them be the 12% outcome XD

[jolly token]

What about 12.2%? lol

[hot gale]

1000 items

[jolly token]

A percent of Pi

[hot gale]

and 122 be the outcome

Round to 3 decimal place and multiply until integer

But either way, I'm using the Random Range one. I just wanted to know what others thought.

[wise fossil]

I would chose this method

[hot gale]

I already did, yeah.

[jolly token]

Well you did a good job

[hot gale]

Been programming a hell of a long time, so it was an easy choice for me. I just wanted to have text evidence to show my friends that the other option was pointless.

[jolly token]

Search about Weighted Random and that might help even more.

[undone coral]

does it create a lot of strings?

like lots and lots and lots and lots of text

[misty glade]

Not too many. 3-4 maybe per prefab

[undone coral]

i am familiar with your game so i can't see how 1.8MB of allocations are possible

it's UGUI right?

are you instantiating something in a way that builds a big list of items

but... for some reason, after every item is added, a Canvas.ForceLayout or something similar is called?

you might want to disable the layout group you're instantiating into while you do it

then re-enable it when you're done

[sly grove]

one way is put it in its own scene and async load that scene in.

Seems crazy though... how complicated is this thing?

1.3 MB of garbage allocation though

that's quite a lot of data

you are doing something that allocates a lot of heap memory in that code

[misty glade]

Yeah, I'm not sure what the allocations were (sorry, was AFK a few hours). I am doing something that might be messing with canvas.forcelayouts - basically I'm building this dialog box:

There's a number of crew members, they have icons for which class they are.. so .. there's some level of nesting the prefabs h ere

but the canvas redrawing is due to the scroll rect content panel building - I'll have to go through the code a little bit and make sure it's only doing it once at the end, but the content gets created, then the canvas is rebuilt so that the scroll rect has the proper sized content rect.. Now that I think about it though, I'm handling the content panel size manually so I might not need to do any canvas forcelayout-ing

[misty glade]

UGUI, yes.

[misty glade]

I wrote a library for this if you want something simple - https://github.com/cdanek/KaimiraWeightedList

Question: What is current best IoC Container / Dependency Injection extension for Unity?

I used to use Zenject, but it's not maintained anymore.
I'm currently doing it manually but this feels little too tedious.

[crystal parrot]

Does anyonw know a way to do it? i never receive any response on this discord

[mint python]

Couldn't you just use the displacement map on the material?

[crystal parrot]

i want it baked to a mesh (used for collision and lightmap)

https://www.youtube.com/watch?v=l-6-kwWYHkU&t=166s

this is what i want i think

but too expensive

[mint python]

From a code perspective, the answer is to write code that does that.. I don't think there's a shortcut.

But unless you're generating meshes on the fly (and lightmap implies baking to me) I would just bake the displacement in a 3D package and import the mesh.

[crystal parrot]

i want to do it using code

we have a tile engine

and many textures (280)

if i could generate the mesh based on the tile + displacement map then it is easier for us

than doing 280 different tiles

our tiles

result using tesselation

i want to generate the tesselated mesh

instead of doing it every frame

[mint python]

Then you need to write the code that does it...

[crystal parrot]

I see, there i no sample? nobody ever did it?

or any asset, i don`t know the name of this

[mint python]

Mega-fiers did it! How much is your time worth? 🙂

[regal olive]

Hello everyone
I have a code to receive the data from a sensor and it rotates
Now I want to transform my object in the sence...
How can I do that?
This is my code

        //Debug.Log(data);
        string[] values = data.Split('/');
        if (values.Length == 5 && values[0] == imuName) // Rotation of the first one 
        {
            float w = float.Parse(values[1]);
            float x = float.Parse(values[2]);
            float y = float.Parse(values[3]);
            float z = float.Parse(values[4]);
            this.transform.localRotation = Quaternion.Lerp(this.transform.localRotation,  new Quaternion(w, y, x, z), Time.deltaTime * speedFactor);
        } else if (values.Length != 5)
        {
            Debug.LogWarning(data);
        }
        this.transform.parent.transform.eulerAngles = rotationOffset;
      //  Log.Debug("The new rotation is : " + transform.Find("IMU_Object").eulerAngles);
    }```

I want to get the value of script
And when my object rotates to a side it transform to that side as well
Can I do that?

This is for my final and I dont have much time left...I would be so glad if someone helps😭

[orchid marsh]

I'm not understanding your use of the word transform 🤔
Are you wanting both objects to have the same rotation?

[wanton lagoon]

Hi guys, I am trying to query the physics shape that I attached to a gameobject in order to get all the overlapping gameobjects. Now in Unreal engine it's a simple get all overlapping actors function but in Unity, I can't figure out how to query this.

[maiden turtle]

idk what that sensor outputs exactly, but I'd guess it gives you absolute rotation in world space. so probably just set transform.rotation

[regal olive]

Just one object...I'm getting data from arduino it's rotating but not transforming around

[maiden turtle]

https://docs.unity3d.com/ScriptReference/Physics.SphereCast.html

[austere jewel]

Depends what you mean by "physics shape"

There are various overlap methods in the Physics class

[wanton lagoon]

Sorry I am not trying to cast any spheres, I have already attached them as components to a game object

[jolly token]

I think you gotta track the overlapping colliders with OnTriggerEnter and OnTriggerExit for generic solution.

1st you need to subdivide your mesh, then, take the height map and offset the mesh based on the height value on the subdivided vertex uv position.

Transformation consists of translation (positioning), rotation and scaling.

yep, and this isn't the channel for that

[regal olive]

Yes

[silk sable]

I generally dislike using the Animator for animations and especially 2D ones, are there good code based alternatives that are worth dumping the animator for ?

Or should I make my own solution

[jolly token]

Do you want Tween? There’s some library like DOTween if that’s what you want

If you still want Unity Animation just not Animator/Mechanim, there is Legacy Animation component which is.. legacy

Or you could just go for something like Spine

Hey all, I’m interested in doing some reading/watching related to how Online Mutiplayer for video games works at a base level

How to deal with things like lag, dedicated/player-hosted servers, etc

Anyone know any good sources for that?

[undone coral]

i found the riot games devlogs about it the most informative

[tight junco]

Interesting, that sounds like a really good source for it

I’m sure Unity has libraries for this stuff but I want to learn about it in depth

[undone coral]

well one thing you'l learn from me is that the libraries you use for this stuff is the least important part of the puzzle

[tight junco]

How so?

[undone coral]

it's totally commoditized

enet versus forge versus mirror versus netcode versus...

none of that shit matters

How to deal with things like lag, dedicated/player-hosted servers, etc
all of this is orthogonal to the library choice, and is much harder. usually people pay a service provider like Playfab for parts of this puzzle, but to do something innovative you'd have to learn how to do orchestration, via something like kubernetes or nomad/consul, CI/CD, moderation

and learn a lot about real world networking, which the riot devlog talks about

if you get hung up on UDP blah blah...

none of that matters. none of it. meaning it is a solved, commodity problem

[tight junco]

Interesting, I was wondering if containerization was used for gaming

It just seems like the most intuitive solution if you’re doing dedicated servers

[undone coral]

most big multiplayer games long predate containerization, it is more accurate to say they've recreated nomad

[tight junco]

Nomad?

[undone coral]

exactly

[tight junco]

I’m not familiar with the term

[undone coral]

https://www.nomadproject.io

i don't know, nobody writing material online is going to know about any of this

Visual Studio C++ on Microsoft Windows Win32 developers don't really concern themselves with this stuff

good luck out there

[tight junco]

Ty, I’m just fascinated by this stuff

Also how servers receive inputs and deal with lag

Is something I’ve been trying to fully grasp

[undone coral]

one perspective is that there are only a handful of realtime multiplayer game genres anyone plays

there's the FPS, there's the RTS, and whatever rocket league is

that's pretty much it

and the solutions to those things are very domain specific - the better games have 1,000 heuristics versus the worse ones, which have many fewer

the heuristics for things like game state prediction come very late in the development process, and they're tailored specifically to the gameplay that was finalized at that point

there's no generic approach to it

[tight junco]

Prediction is really interesting

[undone coral]

so when you have a multimillion budget it happens, and when you don't it doesn't happen

yes but it's like the number of fingers on your hand

it's arbitrary

you can crack open every bio textbook ever written, it's not going to have an answer for why there are 5 fingers instead of 4 or 6

there's no model for it

so someone at Riot who figured out how to improve Valorant's prediction thing... you know, the answer is "budget and time"

[tight junco]

It’s just “whatever works best for the current project”

[undone coral]

it's not like there's a rulebook for a genuinely innovative gameplay mechanic*

yeah

[tight junco]

And there’s general strategies and guidelines but

[undone coral]

there's just stuff that you copy from other games

[tight junco]

Execution is always different based on so many variables about your game

[undone coral]

which should tell you more about the absolute state of multiplayer gaming - that people play like, 3 kinds of multiplayer games

perhaps owned by different people over time, with different characters, but are sort of the same game

so you can look at how CSGO does its particular approach to prediction

and if you aren't doing a CSGO style game

then... it's not super helpful

i personally do not find it particularly insightful, it doesn't help me make a new game. like i said a lot of that stuff comes very very late in the process

same with the bit fiddling delta blah blah that the one guy

who wrote about netcode tha tpeople cite online

i don't even remember - it isn't super meaningful anymore to have X bytes of data transferred instead of Y

you're going to be writing your new game and testing it on a LAN with a gigabit of bandwidth anyway

and if it turns out to be fun, okay, now you can optimize it specific to your game

but you literally cannot serve more than a single digit number of players without orchestration

so while it is possible to create a multiplayer game without a single network optimization, it is impossible to create one without operating a backend server

[tight junco]

Hmm I see

[undone coral]

anyway, that's my perspective

[tight junco]

I’m assuming if you’re making something simple then like, you can probably start with player-hosted servers

[undone coral]

good luck out there

[tight junco]

And direct connection

[undone coral]

i don't think a single home internet user nowadays

[tight junco]

Then later move to containerization

[undone coral]

can figure out how to broker a direct connection to a server anymore

it isn't a reality

[tight junco]

Hmm I guess so

[undone coral]

there's no such thing as "i punch in an IP address"

exactly zero people will play such a game, in a world where the #1 reason your indie multiplayer game will die is lack of people to play against

another perspective is you should be studying how to write a good bot

because that will be higher ROI

[tight junco]

TRUE

Game AI terrifies me

I want to do things like strategy games

And bots for those in particular are scary

At least they seem to be

[undone coral]

well it's really fun to write a bot

there's a guy here who wrote a puzzle fighter bot

that works really well

[tight junco]

Yeah, because there’s also a big difference between like, player bot AI and NPC AI

It’s an aside but it really is a different beast

[undone coral]

i should clarify that if you went and

@tight junco phone called someone at Riot Games and asked them

"how early do you start thinking about these network optimizations"

they will say day 1

i don't think that is helpful advice though. they have a $400m budget to spend on developing valorant, if they want to write code they never use they can do that

and besides, do they make any original titles? they have the benefit of specifying ahead of time everything they want to copy. a big reason their games took so long to release is new stuff kept coming out they wanted to copy!

they still wound up using Unreal, and i think if you want to make an FPS, you should too

if you want to make an RTS, make a Starcraft 2 mod

and if you want to make rocket league, pray

[tight junco]

I see I see

I guess its something they keep in the back of their mind too

you just know these things when you're experienced

[undone coral]

i've never written an FPS

i wouldn't dare to

[misty glade]

my "AI" for my puzzle battle game is like 15 lines of code 🙂

Done and done dusts hands off

(also, it's very dumb)

At some point in our dev, closer to launch, we're probably going to spend a bit more time and effort on this kind of thing, but.. if your data models and domain tier (business logic, game logic, whatever you prefer to call it) is ... thoughtful and well organized, the actual "AI" part of the game isn't too hard. Making it good, humanlike, not cheaty.. well, that's harder but also maybe not required for most games.

Pathfinding AI is probably a whole class of hard, though.

[tight junco]

I mean for that you have the navmesh thing

[misty glade]

@tight junco if you ever want to, I'll give you a brief tour of how I'm doing multiplayer for our puzzle battle / idle+ game. Short answer: Docker, C# containers, networking with Ruffles, serialization with MessagePack and JSON.net, cloud with Azure, CI with GameCI.

[tight junco]

But I know, I tried my hand at it

Damn

How long itd take you to learn all that?

[misty glade]

I dunno, I didn't really have anyone to tell me what good solutions were so I sort of just fell into the ones I use. They may not be the best, but they work pretty well for us.

There's things I would do different on the client ( @undone coral recommended UniRX to me early on but I didn't choose it - in retrospect, I would have )

[hollow wing]

Hey guys Hoping someone can help me figure out where my syntax is wrong and causing me what I assume is a never ending loop. First picture is the code that worked (basically if the InnerWall goes past the OuterWall come back), The second Code was the endless loop (get wall to go forward until it went past the wall then come back).

[misty glade]

Oh, also, admin tools - blazor/razor

[misty glade]

You gotta pastebin that bro

[hollow wing]

sorry lol how do i paste bin?

[misty glade]

https://pastebin.com/ paste, select C# as the syntax

and... without looking too much at the code, it's probably a #💻┃code-beginner or #archived-code-general question

[hollow wing]

got it ill move it over sorry 🙂

[misty glade]

(also I'd recommend you remove all that whitespace, holy moly) I recommend you try out: https://github.com/JosefPihrt/Roslynator to help you clean up your code

[hollow wing]

yeah I'm only 3 weeks in to coding so lot to learn. Probably shouldn't figure my code is anywhere near advanced anyways lol. working on those tips though thanks.

[misty glade]

Yeah, all good - for 3 weeks in, great work. But as you go, try to learn and format your code like others because there's good reasons for it. It's easier to read, simpler to understand, will speed your own growth as you can focus on what matters instead of bugs that will arise because of sloppiness. Paste your code and repost your question in general and I'll have a stab at it

(your indentation is a complete mess and is likely making it harder for yourself to debug - you're likely getting or going to get completely avoidable bugs from just that)

[velvet plaza]

I am using PlayFab, a Microsoft service to manage game accounts, player data etc.
I am trying to make a button in Unity to delete the player's account.
I found out you need to do that with a CloudScript from the forum post. I haven't used that before.
I used this documentation page: https://docs.microsoft.com/en-us/gaming/playfab/features/automation/cloudscript/writing-custom-cloudscript
I made this C# method:

    public void DeleteAccount()
    {
        PlayFabCloudScriptAPI.ExecuteFunction(new PlayFab.CloudScriptModels.ExecuteFunctionRequest { FunctionName = "deleteAccount"/*, FunctionParameter = playFabID */}, OnSucces => { messageText3.text = "Account deleted successfully!"; AccountWindow(false); LogInWindow.SetActive(true); }, OnError);
    }

And this CloudScript function.

handlers.deleteAccount = function (args, context) {
    var request = {
        PlayFabId: currentPlayerId
    };
    // The pre-defined "server" object has functions corresponding to each PlayFab server API 
    // (https://api.playfab.com/Documentation/Server). It is automatically 
    // authenticated as your title and handles all communication with 
    // the PlayFab API, so you don't have to write extra code to issue HTTP requests. 
    var playerStatResult = server.DeletePlayer(request);
};

But when I execute the method, this error occurs:

UnityEngine.Debug:LogError (object)
PlayFabManager:OnError (PlayFab.PlayFabError) (at Assets/Scripts/PlayFab/PlayFabManager.cs:115)
PlayFab.Internal.PlayFabUnityHttp:OnResponse (string,PlayFab.Internal.CallRequestContainer) (at Assets/PlayFabSDK/Shared/Internal/PlayFabHttp/PlayFabUnityHttp.cs:222)
PlayFab.Internal.PlayFabUnityHttp/<Post>d__12:MoveNext () (at Assets/PlayFabSDK/Shared/Internal/PlayFabHttp/PlayFabUnityHttp.cs:160)
UnityEngine.SetupCoroutine:InvokeMoveNext (System.Collections.IEnumerator,intptr)```
Please ping me if you can help

[undone coral]

No function named deleteAccount was found to execute
it sounds like you didn't deploy your cloud script

or maybe didn't declare it correctlty

[orchid marsh]

https://docs.unity3d.com/ScriptReference/Transform.RotateAround.html to rotate around an axis in world coordinate. The doc has further info.

[velvet plaza]

fixed it, sortof

[velvet plaza]

I used the wrong command

I should have used PlayFabClientAPI

But now there is a new problem, the player is deleted but if I log in after that again, the account is restored again...
and it says two players in the list but it shows only one

Hello, I'm studying jobs and I have a question

What happens if I don't use jobHandler.Complete function to the job?

I'd like to not block the main thread and just start the job in parallel, without blocking the rendering and lowering fps

[sly grove]

nothing in particular. You just won't be able to guarantee that the job has completed yet at any given point of your code

[lament briar]

Well, not my objective, so it still works?

[sly grove]

Complete doesn't affect or modify the execution of the job at all

it just tells the main thread to wait for its completion

[versed warren]

Anybody have a solution to this texturing issue im having? I am texturing every tile realtime using TExture2D and am generating the terrain using unity Mathf.PerlinNoise

In between every tile their is a line

When I seperate the textures if their are multiple colors on the tile it will leave a small line on the side

I cant find the issue for it

[sage radish]

What wrap mode are you using for the textures?

[versed warren]

Im not using a wrap, This is my code toe create the texture

texture.filterMode = FilterMode.Bilinear;
texture.SetPixels(colorMap);
texture.Apply();

Okay I set the texture wrap mode to clamp and it looks much better but there is still some oddity in betwwen tiles

Like I can see a line in between the tiles

[plucky laurel]

its because of mipmaps

lower mips are low res and bleed color on edge

2 things you can do that are simple, 1. adjust mip map bias, or 2. add border to tile textures, 2-5 px, and offset uvs to match that

actually computing perfect uv offset distance would involve some math but i dont know about it

[plush hare]

I'm trying to design my own sweeptest. Suppose I have a circle that has raycasts shooting out of the center in a radial design all along the bottom half of the sphere (in this I only show one).
The sphere moves down a certain amount until the raycasts hit something, but the sphere will also likely be penetrating whatever it hits. How do I calculate the depenetration? The sphere is only allowed to depenetrate by moving upwards.

[plucky laurel]

you should predict it before it happens

project the sphere ahead, gather all the penetration data and decide where the sphere should land

or that wasnt the question?

[plush hare]

I don't think that's how its done

or even possible that way for that matter

most collision detection moves into an object, computes penetration, and then moves out of it

that's how all character controllers work

[plucky laurel]

where did you get that from

[plush hare]

https://docs.unity3d.com/ScriptReference/Physics.ComputePenetration.html

[plucky laurel]

and?

[plush hare]

One particular example is an implementation of a character controller where a specific reaction to collision with the surrounding physics objects is required. In this case, one would first query for the colliders nearby using OverlapSphere and then adjust the character's position using the data returned by ComputePenetration.

read

I don't know what else to tell you

[plucky laurel]

alright, so you got all that from a utility method in unity api, gotcha

[plush hare]

Why are you acting so smug?

Have you ever written a depen algorithm?

[plucky laurel]

so 1. no comment

2. no comment

any actual refutals?

[untold moth]

There's a difference between regular and continuous dynamic collision. The latter one predicts the collision ahead of time based on object's velocity.

Regular collisions are indeed penetration based if I'm not mistaken.

[plush hare]

How do I go about solving this?

[versed warren]

bruh this the help channel stop bitching

[untold moth]

Use continuous collision detection.🤷‍♂️

[plush hare]

The whole point of my question is to understand the logic behind that whole system

sweeptest in specific.

[untold moth]

It's not that complicated. When using continuous collision detection, the physics system casts the object collider in the direction of it's velocity, and if it hits something, it limits the movement to be applied.

[plush hare]

I understand that

I just want to be able to design my own system with fewer raycasts, to increase performance.

There's no velocity in my example either

it simply moves the shape of a wheel downward until it hits something or hits the max length

https://docs.unity3d.com/ScriptReference/Rigidbody.SweepTest.html

exactly what this does

[untold moth]

Obviously, if you don't rely on physics system you'll have to do it yourself, yeah. I've no clue about the underlying implementation, but it's based on Nvidia's physics afaik, so might be able to find it's source code.

[untold moth]

Yeah, pretty sure that's what continuous collision detection uses under the hood.

[plucky laurel]

problem with continuous is that it takes control, so you have to do it manually, like kcc/ecm

[plush hare]

Yeah I had no problem using sweeptest with kinematic objects

[versed warren]

Yeah thats what I was thinking, I was initially hesitant about the process because it will ultimatley slow the texturing down

But im working on setting up that now

I have no idea how to change UV'maps realtime but ill find out soon

[plucky laurel]

you can automate that

[versed warren]

Whatchu mean?

Im writing all of it through code if thats what you meant

[plucky laurel]

    public void Pack()
    {
        texture = new Texture2D(2048, 2048, TextureFormat.ARGB32, 3, false);
        var rects = texture.PackTextures(packingQueueTextures.ToArray(), 2, 2048, false);

        for (int i = 0; i < packingQueueAtlasTextures.Count; i++)
        {
            var atex = packingQueueAtlasTextures[i];
            atex.OnAtlasUpdate(this, rects[i]);
        }

        texture.filterMode = Rendering.Cfg.atlasfilterMode;
        texture.wrapMode = TextureWrapMode.Clamp;
        texture.mipMapBias = Rendering.Cfg.atlasmipBias;
        texture.minimumMipmapLevel = Rendering.Cfg.mipMinimum;

        pixelSizeX = 1F / texture.width;
        pixelSizeY = 1F / texture.height;
    }

when processing textures you can generate an atlas and store uvs of each resulting tiles

then you can add padding while packing

on runtime or editor you can apply the uv offsets

in my case i had AtlasTexture class which had atlas tex ref, offsets, all info necessary for drawing it

but you should test before doing all that if it even works in your case

[versed warren]

Yeah, Im not sure how to change the mip map bias tho

[plucky laurel]

texture.mipMapBias =

I want to press the back button on an android phone programmatically after a event occurs. How would I do this?

[jolly token]

Well back button maps to KeyCode.Escape, so is that question 'how to simulate esc key input'?

Or do you need to do something with Android side?

[inner juniper]

Thanks for the reply. Yes I want to simulate esc key input.

[jolly token]

Can you have like input mapping class that can simulate it for you? I think that would be easiest way

Or if you're using new Input System, you could try InputSystem.QueueEvent

[inner juniper]

I'll check this out

[inner juniper]

I want to close an interstitial ad after it is done playing programmatically. I have access to the event that fires when the ad is done, its just closing the thing that is the problem.

[jolly token]

So it is something to do with Android 🤔

Doesn't your advertisement sdk gives you that kinda API or option?

[inner juniper]

negative

[jolly token]

At worst you might have to write Android plugin

[inner juniper]

and at best? xD

[jolly token]

At best there might be some solution exist that I have no idea about

😌

[inner juniper]

Im going to submit a support ticket to see if Unity will help with the problem. Thanks for your help broski. @jolly token

[jolly token]

Good luck with your journey

[devout hare]

They won't, unless you're paying for the Pro/Enterprise licenses

[hexed meteor]

I was modifying one of the scripts of the NavMesh components, and suddenly I get this error claiming that the class NavMeshSurface cannot be found anymore... which is false though.

No idea what to do 🥴

[livid kraken]

So right now Im storing a extra byte in the first uv chanell of a mesh. That byte simply stores the index for the mesh in a global texture array. This adds to a byte per vertex. Is there a smarter way to pack a single value on a mesh to be then interpolated in a shader ?

Having the index as a property in the shader is a no go since it will break batching

[upbeat path]

which namespace is NavMeshSurface in? check your usings

[hexed meteor]

UnityEditor.AI

[upbeat path]

that doesn't sound right because NavMeshSurface is also a runtime component

mine says Unity.AI.Navigation

and my NavMeshAssetManager says Unity.AI.Navigation.Editor

[hexed meteor]

Hm that doesn't seem right either

[upbeat path]

thats the editor code, look in runtime code

which version are you using? The package or from git?

[hexed meteor]

I'm using the git package

how can I tell the difference between runtime and editor code ?

I'm probably too much of a noob for all of this

barely know what namespaces are

[upbeat path]

Inheriting from : Editor is a bit of a giveaway

Also the Editor code is in the Editor folder and the Runtime code is in the Scripts folder

so in the git version NavMeshSurface is in UnityEngine.AI

and NavMeshAssetManager is in UnityEditor.AI

[lament briar]

Hi, I'm trying to use a job to serialize and save a large json file. Currently I do it without jobs and I just serialize/deserialze a class, however trying to use jobs to do that doesn't actually work since I can't have a class as a parameter. Is there anything I can do to not refactor my whole code to use a struct (and native collections) instead of my current class to store a chunk's save?

Maybe some thread-safe container where I can store my class, or some sort of mutex for jobs... idk

[tribal pivot]

use a job to serialize and save a large json file

why

How? You cant do IO from jobs

[lament briar]

to do what jobs have been created for: optimize, parallelize and reduce lag

[lament briar]

well damn, I really don't know how to reduce lag on chunk loading

[tribal pivot]

But that doesnt mean every single thing can be solved by jobs. How would you serialize json in a multithreaded way?

[lament briar]

yeah

"it doesn't work" is different from my reason

[tribal pivot]

No, "its not the right solution for your problem"

[lament briar]

If it worked it was

*if it could work

Or, it was one of the solutions

[tribal pivot]

I dont know why you're making that argument.

Yes.

Congrats

[lament briar]

idk man you asked why and then was unhappy with what i answered

it doesn't work, well bad for me, doesn't mean my "why" is a bad answer..

[tribal pivot]

1. Perhaps look at serializing less data. Do you really need one save file, or could you make a different file for each type of save? So you dont need to serialize every single thing, every time.
2. Maybe look at different serialization methods, there's more out there than JSON.
3. Where is your bottleneck? Serialization or saving? How do you serialize, how do you save?

[lament briar]

Both serialization and writing to file are taking a lot of time

The save is already splitted in chunks

[tribal pivot]

How do you save? You could do it async

[lament briar]

They hold necessary data such as positions of objects or which objects

Async seems a wonderful solution

It's what I was tryuing to achieve with jobs

[tribal pivot]

https://docs.microsoft.com/en-us/dotnet/api/system.io.file.writeallbytesasync?view=net-6.0

[lament briar]

Thanks I'm gonna try that

any solution to the serialization?

[tribal pivot]

What do you use atm? I'm sure there are a fair amount of json serializers out there, but perhaps its possible to switch to something else

[upbeat path]

have a look at BinaryFormatter

[shadow seal]

BinaryWriter and BinaryReader, BinaryFormatter is insecure

[somber swift]

Yeah, dont look at binaryformatter

[lament briar]

I'm using JsonUtility

it's included in Unity

to/from json to serialize and writeall/readall to use a file

[upbeat path]

BinaryFormatter is a virtual drop in replacement if you are already using Json, if he was worried about security he wouldn't be using Json in the first place

[shadow seal]

BinaryFormatter allows me to execute code in your process

[upbeat path]

so zip it before saving if that's your concern

[somber swift]

So explain me the security issue with json?

[shadow seal]

Or take Microsoft's advice and just use BinaryWriter/Reader?

[upbeat path]

because any idiot can open it and modify it in Notepad

[dreamy bone]

Hi, I was hoping you guys could show some light on a situation I´m having. You see, I´m making a multiplayer using photon and I have an array of sprites to select the player's avatar. All working fine, but I want to make a condition that if (balanceof > 0) a specific element in the array it is set as avatar. How can I implentent this? This is what I have tried but it´s not working: if (balanceOf > 0)
{
avatars[1].SetActive(true);
}

[upbeat path]

I agree, if you were starting from scratch, but that is a lot of work to implement when you already have a Json solution

[shadow seal]

How is it?

[somber swift]

Lol, thats not security issue. From official binaryformatter security guide made by microsoft:

The BinaryFormatter type is dangerous and is not recommended for data processing. Applications should stop using BinaryFormatter as soon as possible, even if they believe the data they're processing to be trustworthy. BinaryFormatter is insecure and can't be made secure.

[devout hare]

If someone edits JSON they can get more in-game currency or lives or whatever
If someone edits files read in with BinaryFormatter they can execute arbitrary code on the computer
they're not comparable

[rugged radish]

different kinds of security issues
arbitrary code execution vs modifying the files

[somber swift]

For more information: https://docs.microsoft.com/en-us/dotnet/standard/serialization/binaryformatter-security-guide

@brave solstice You can post jobs on the forums. Otherwise you can ask help questions here.

Likely in #💻┃code-beginner though if you don't know what you're doing.

[brave solstice]

thanks

[lament briar]

Could I use async for file writing and reading (maybe a singleton that handles that) and jobs to serialize and deserialize?

So, every time a file is read it calls a job to serialize that, and then the job sends back the data in a class

and to write that, first you call a job to serialize and then the job adds the class to a manager (singleton) that updates it in its update

[flint sage]

I don't know much about jobs but doing serialization in jobs seems like a bad idea

[gentle topaz]

just use async.. Is your data taking like multiple seconds to save or something?

[lament briar]

yes

each time I move in my terrain it lags, freezes

that's a shame because I worked my a** off to have about 150 fps in game, and then it freezes every time I walk

[flint sage]

Off load it to a different thread instead of using jobs

[somber swift]

Why are you saving it every frame?

[lament briar]

Not every frame

[gentle topaz]

if loading / unloading some chunks takes multiple seconds, I think something else is wrong with your logic

[flint sage]

Also don't seriailze json for that

[lament briar]

just when I move and a chunk has to be destroyed

[somber swift]

So every single frame you move?

[lament briar]

or created (then it's the reading that makes it lag, about half the load is serialization and half reading or writing in the file)

[flint sage]

You'll want something else than json, json is likely too verboes for your data, inflating the size

[lament briar]

No

Every time a chunk has to be loaded or not

[flint sage]

Besides most serialization json libraries are pretty slow

[lament briar]

if I'm walking in a direction, I'd say that it happens once about every 4/5 seconds

A chunk has to be a certain distance from being activated or deactivated

[gentle topaz]

well if it's async it shouldnt freeze

[lament briar]

For file reading and writing

[somber swift]

Ok, but still, why it needs to be saved all the time? Why not save it once after the playing session?

[gentle topaz]

has this been actually profiled?

[lament briar]

If I'm unloading and destroying a chunk I have to save it

can't walk for miles and maintain hundreds of chunks deactivated at once, maybe in my ram

[lament briar]

yeah that's how I know it's this that's making it lag

1/3 of the lag was the instantiate method, and I took care of it

[somber swift]

Thats true, i didnt realize it was about chunks at first

[gentle topaz]

well then yeah what Navi said.. If you are just saving voxel data, you might want to use something other then JSON

[lament briar]

Not voxel

It's a custom mesh + object's data

I've got about 5k objects per chunk 😛

each one has its transform saved

and the object's id

[gentle topaz]

what? what is your game then?

I thought we were talking about chunks

[flint sage]

You're saving a mesh as json?

jfc that's bloated af

[gentle topaz]

i have been assuming its something like minecraft

minecraft would never be saving 5k objects per chunk

[lament briar]

The world is a bit like valheim

a normal 3d world

(graphics is low poly though)

[gentle topaz]

so its just a heightmap?

[lament briar]

heightmap + objects, currently yes

gonna add living entities to them

ah, and biome data (so a grid like the heightmap)

[shadow seal]

Are the objects decorations like grass?

[lament briar]

yes

[gentle topaz]

well this is not a good way of saving

you want to only save modifications to the original seed

[lament briar]

grass has a role in the world

can't generate that randomly

I need to "cut it" and replant it

[gentle topaz]

well save the ones you cut and ones you plant

but not all the ones you havent touched

you can enter and exit a chunk in minecraft and have it save zero data about it

if you made no changes

[lament briar]

And if I changed one thing, I'd have to reserialize everything

thus, since grass has a role in the game player would very likely notice changes, also because they hold important items (like some flowers)

[gentle topaz]

why would everything need to be reserialized? you would just enqueue that one change to a queue of things that need to be saved when the chunk is unloaded

[lament briar]

I was thinking about writing manually a script that reads "slowly" the data, like 50 objects per frame

a bit like I've done with the instantiate method, I created a singleton that holds a queue of items that needs to be spawned, and it spawns them slowly

but that would be really a lot of work and prone to errors

[lament briar]

How?

Everything I do is literally saveClass.toJson and saveClass.fromJson

[gentle topaz]

yeah, and thats what im saying is a bad way to save large worlds

[lament briar]

😦

hoped everything worked well, writing any other system will probably take days and I was happy I had almost finished my procedural world system T.T

[regal olive]

Thank youuu

[gentle topaz]

you would need to make sure things are deterministic based on seed, and probably create some sort of ID system for objects in the chunk, then if you cut down a tree and it split into logs the player could pick up, then the player unloaded the chunk, it would save that tree with ID 1 (for example) was chopped down, and that the log items exist at their positions and rotations.

so your amount of saved data for that chunk would be tiny

then when you load the chunk, it regenerates from the seed, then makes all the changes

so it makes sure that particular tree doesnt spawn, and that the log items do

this is pretty much what all proc gen games with many objects do in some form

except poorly coded ones like terraria :P

[lament briar]

ID system for object is really a problem that I was trying to solve

I was wondering, "how can I say to the class that holds the file that object X has been deleted"?

[gentle topaz]

well each chunk could just start at ID 0, and every time something was created during the generation in the chunk, it would assign the ID to that object and increment the ID

and if thats deterministic, the IDs will always be the same even if you leave and come back

[lament briar]

mmh.... yeah, that was what I was thinking

[gentle topaz]

and the ids would be ushorts to save on some space

[lament briar]

Maybe the class could also store a dictionary that's initializated every time a chunk loads, the key would be the object's id and the value would be the object

to have a faster search and delete method

anyway loading is still a big probelm

[gentle topaz]

I would imagine its a bit like a replay system

its as if the chunk starts off as it was when it first generated

then it quickly makes the most recent changes

then displays it to the player

obviously there are a lot of specifics here, but thats the general idea

[lament briar]

Well... the chunk is completely modificable

terrain, biomes, objects

at this point I'd just save everything

I just need a faster method to load it...

generating also takes a bunch of time

at least, current method is really resource intensive and it's another of the scripts that I need to optimize, and is based a lot on Random.Range without a seed

[shadow seal]

Random is seeded, if it wasn't it'd be the same every time

[livid kraken]

You can also seed Random with the same seed so its deterministic

I think

[shadow seal]

Aye

Hey guys, does anyone know why Instantiate(Gameobject, position, rotation) doesn't include rotation when using Particle system, it's always (0,0,0) -> degree rotation on axis, when it is executed. This Gameobject that I am instantiating is an explosion which always points upwards with no regard for rotation (I want to include rotation as well). Could anyone point out a potential issue? Thank you in advance 🙂

[livid kraken]

Is rotation a quaternion ?

[heavy juniper]

It is @livid kraken

Instantiate(obj : GameObject, position: Vector3, rotation: Quaternion)

What I meant by 0,0,0 is that no angle component is other than 0° 🙂 I converted 3 angles to Quaternion, which has 4 elements, yes (unmodified since conversion)

    {
        Instantiate(ExplosionVFX, transform.position,ExplosionRotation);
        CheckCollision();
    }```

I even tried passing ExplosionRotation as separate parameter (as you can see) but to no avail, even though Quaternion is not (0,0,0,0) before being used by Instantiate()

I Instantiate twice however, once to instantiate explosion GameObject and the other time to instantiate animation, both scripts having separate logics hence 2 instantiations

[sly grove]

your particle system might not care about the object's rotation

especially if it's simulated in world space

[heavy juniper]

I changed to Render alignment: Local to tackle this issue

was not much of a help

it's actually in Local

[sly grove]

This is more of a #✨┃vfx-and-particles question than a code question

[heavy juniper]

Thank you, I will redirect my question there

[livid kraken]

Yo doc..your always up for a discussion. Im gonna copy my q from earlier So right now Im storing a extra byte in the first uv chanell of a mesh. That byte simply stores the index for the mesh in a global texture array. This adds to a byte per vertex. Is there a smarter way to pack a single value on a mesh to be then interpolated in a shader ?

In the mean time I found a paper confirming my aproach that was published in GRAPP

[livid kraken]

It did

Since for it we strip the mesh of everything else

It has a flaot3 pos and float3 uv

Hehe

A scalled to 0 vert at index 0

And what encoee the index in its x?

Yes. For the quest we just baked all that we wanted in blender so dont even need normals,unless the specific chunk has env reflections

But I have ideas for a system that uses the concept of packed pbr maps from that one blog post with this global array aproach

That way each slice can be a albedo normal map and smoothnees

And if we treat it like a material it could be a pretty dope way to render environments

Combined with the new surface gradient bump mapping unity release

Well new I think its from 2019

[livid kraken]

The shader graph one ?
