[brisk spruce]

so I would make a PipeManager service which handles all CRUD operations for PipeSegments

Should be at a single point I think?

[uneven mauve]

Right, so a new script called PipeManager then what's that next bit?

[brisk spruce]

Well what Im talking about might not be super relevant to you if you arent setup for doing like a whole service layer architecture

I think youd want a SO is the non dependency injection approach?

[uneven mauve]

I have no clue about Unity architecture to be honest

[brisk spruce]

SO called PipeManager or whatever and it has like,

CreatePipe
GetPipe
UpdatePipe
DeletePipe

your various CRUD operations to mutate your pipe segments

and then prolly a method like

GetSiblings
``` for sure

This service handles the job of keeping track of every pipe segment, the sibling relationships between pipe segments, and the Child->Parent lookup table for what children pipe tiles belong to which segment

[uneven mauve]

I'd love to do this but no clue what that means

[tiny pewter]

Now I understand what you means, you maintain a different hashtable for storing coordinate to segment

[uneven mauve]

Like I can make a C# file but from there, actually knowing what needs to be programmed first is a little confusing

I get the logic and can program it

[brisk spruce]

start by writing our the methods you probably need, I presume you probably want your basic CRUD functions for a "Pipe Segment"

And then make an empty class called PipeSegment or whatever as well

prolly needs an Id which is randomly generated, I usually use a Guid

[uneven mauve]

What happened to no classes

[brisk spruce]

I dont actually know if you really need a class to be honest for this, the only actual data the pipe itself holds is just an arbitrary ID

I guess you need your "pressure" value I suppose

[uneven mauve]

What is the service layer architecture?

I'm trying to work close to production first time

[brisk spruce]

its the concept of breaking your logic into "layers" by responsibility

So personally I go for 3 layers:

1. GameState Layer, which holds the "state" of the game for mutable info that can be changed and needs to be read/write from as a sort of Pub/Sub model.

2. Service Layer, this is where all my logic actually goes for "doing" things, its the "game engine", its where like 99% of my code lives

3. MonoBehavior or "scene" layer, this layer is all the MonoBehaviors applied to my GameObjects in the scene, and the only stuff that goes here is all the logic for what you actually see in the game

[uneven mauve]

Right and I create the other layers how? Through scripting?

[brisk spruce]

its an organizational concept but typically I just make sure to keep em organized by folder structure and matching namespace

So I have like Assets/Scripts/Services, Assets/Scripts/GameState and Assets/Scripts/Entities (Entity is the term I personally use for the things in layer 3)

[uneven mauve]

Right

Well first things first, I need a script to actually store the dictionary

That's challenging

So no MonoBehaviour is needed?

[brisk spruce]

If you dont have dependency injection setup you'll use a ScriptableObject as your service I believe

at which point we start to exit my zone of knowledge as I dont use SOs, I typically use dependency injection for constructing my entire stack

[uneven mauve]

I'm still very confused. idek what dependency injection is lol

[brisk spruce]

at its simplest form its just when you pass a reference of a thing B to another thing A (injecting it), such that now A can "depend" on B. Thus Dependency Injection

[uneven mauve]

ah

[brisk spruce]

the most classic form of it in C# is Constructor Injection

public class MyServiceA
{
    public MyServiceA(MyServiceB serviceB)
    {
        ServiceB = serviceB;
    }

    private MyServiceB ServiceB { get; }

    // and now logic here can use ServiceB as a tool to do stuff
}

note how a ref to a "MyServiceB" was injected into MyServiceA which now depends on it and uses it. thus, "Dependency Injection"

[uneven mauve]

right I see, ty

I'm gunna make a blank script, attach it to an empty

Then define a dictionary

public class Pipe
{
    public string type;
    public int health;
    public Vector2Int coordinates;
    public List<Vector2Int> neighbors;
}

Is this bad then?

Ignore the actual values

But the concept

[somber pendant]

hey friends, i'm trying to deserialize an enum that uses bit flags (ie something like)

[Flags]
enum Terrain {
NORMAL = 0,
FOREST = 1,
SWAMP = 2,
DESERT = 4 }```

in json it's something like terrain = "FOREST", however it seems that the deserialization doesn't like human readable string enums (it wants an int) which is especially troubling for me in the case of bit flags, ie. something like FOREST|SWAMP. 

XML handled this stuff fine, why does json, the superior format, seem to struggle with it so bad? Should i be making an enum wrapper for handling the deserialization of this? no matter what i do i feel like my solution will be clunky and i will dislike it.

Ultimately it needs to be human readable and i won't accept a "solution" where my bitflag enum has to be represented as an integer like 145878 in json.

[jolly token]

What Json serializer are you using

[somber pendant]

the unity one,

JsonUtility.FromJsonOverwrite(data, feature);

seems like it only accepts integers for enum fields which makes me sad

especially for bitflag enums

i think newtonsoft json utilities doesn't fare much better

[brisk spruce]

I believe it supports it
https://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_Converters_StringEnumConverter.htm

[novel plinth]

Unity's JsonUtility is special... by that I mean, it sucks
I'd avoid newtonsoft personally. and since 2022.2.x and above Unity supports stj

[somber pendant]

stj?

newtonsoft actually fails to deserialize my data properly so that alternative i have ruled out for other reasons

i mean, i could ptobably debug it but i already spent too much time on this silly issue

[novel plinth]

changing serializer and praying that it'd work sound a bit ...eh

debug it

[somber pendant]

i'm not using anything special in my class, so newtonsoft json failing to deserialize it caught me by surprise

i think it's the structure of the class that might have messed with it

since it's unity i'd rather avoid using other non-stock solutions in this case

not sure if [Serializable] and [SerializeField] play nice with newtonsoft

[sly grove]

Newtonsoft has totally different rules about what it does and doesn't serialize. Those attributes are irrelevant to it. You'll want to check their docs if you want to use it

[ancient jackal]

Hi, how do I make grid based strategies/games in 3D? I know that's a broad question, so to narrow it down, I'm interested in how I can make grid based placement of units. Do I use tilemaps or just make an Model/View sorta thing where I have non-MonoBeh Grid and Cell classes and a View class which places them in the world?

[sly grove]

Yes a model/view architecture is pretty standard for strategy games

You can use Unity's Grid component to make spatial positioning and calculations easy (presentation layer)

[ancient jackal]

Do you have any docs/tuts for them online? Couldn't find documentation for this separate component, although it was the first thing that came to midn for my task

[sly grove]

you can't?
https://docs.unity3d.com/Manual/class-Grid.html

[ancient jackal]

oh thanks so much

[rare tiger]

Speaking of which, does anyone have recommendations for unity c# Json serializers

I had a not very fun time with my current project learning how unity's shitty jsonutility works and I'd like to not have to do it again

[sly grove]

I don't serialize Jasons. They're much too emotionally unstable

As for JSON, look into Newtonsoft JSON

[rare tiger]

What about mikes

[sly grove]

Unity's serializer is generally the fastest one around afaik though, if you can work within its limitations

[rare tiger]

Yeah it's fast since it pretty much leaves it up to you to format everything into something usable. Which is fine I guess. It's just fucking annoying and tedious. Especially on the first time

Like it took me a day or two to figure it out

[sly grove]

well the list of things it can serialize are here: https://docs.unity3d.com/Manual/script-Serialization.html#SerializationRules

[rare tiger]

Especially realizing you need the system.serializable tag on all classes you wanted to cast the data to. I had a lot of frustration as to why I had null reference errors

[flint sage]

That's pretty normal in serializers though

[sly grove]

every serializer has rules about what will and won't be serialized

you will always need to spend time adjusting your datatypes to fit within those rules

[rare tiger]

Yeah ofc, would've been nice to know that ahead of time tho. Yk, a bit better documentation on how to use it other than some YouTube tutorials and stack exchange code snippets

[flint sage]

I uuh.. did you see this link?

[rare tiger]

When I was look for it originally I didn't find it

[sly grove]

Yeah it's documented.
https://docs.unity3d.com/ScriptReference/JsonUtility.ToJson.html says:

Internally, this method uses the Unity serializer; therefore the object you pass in must be supported by the serializer: it must be a MonoBehaviour, ScriptableObject, or plain class/struct with the Serializable attribute applied

[rare tiger]

Maybe because I was searching up Json parsing

[sly grove]

same on the FromJson documentation

[rare tiger]

Maybe I just need to read better then. Idk

[sly grove]

when something's not working as expected the docs should be one of the first things you look at

[plucky laurel]

typically you have some shared context object

you can look at existing bt/fsm implementations to see what they do

its some component, often called "blackboard" where everything writes/reads

or just look at mecanim, with its parameters

same concept

if your fsm is specialized you dont need to abstract variables, you can just declare public properties and use them as is

[harsh canyon]

👍

[sleek terrace]

With my mesh procedural generator, even with dynamic batching on, there is barely a difference in fps

I have seen people render far more triangles wih better FPS, what im I missing?

[plucky laurel]

dynamic batching would not improve performance with massive amount of meshes

it has limitations like 300 triangles per mesh

and it does the batching each frame on the cpu

you can imagine you merging the whole thing every frame

you want it merged, or if you dont want to spend time on the cpu merging you can attempt to use gpu instancing

if you want it merged you can use CombineMeshes api

if your thing is dynamic, you can chunk it and update /recombine only changed chunks

[sleek terrace]

So, I now have to combine all the meshes on the individual hexes into 1 mega mesh using the CombineInstance api?

where can I find this gpu instancing?

[plucky laurel]

google it, unity provides api to instance mesh batches, so you still will have to write it

or you can buy gpu instancer asset from the store

or try finding open source one on github

[sleek terrace]

ok thanks

[plucky laurel]

mega mesh is typically the fastest option if its chunked on modern gpus

but you pay for it with baking time on the cpu

gpu instancing is typically desired in highly dynamic scenarios and also has its ceiling

[sleek terrace]

ok

my material doesnt have gpu instancing

its custom made btw

[plucky laurel]

i dont know what that toggle does but it never did anything significant

if you want to use gpu instancing you have to either write it or rely on custom written instancing system

that toggle may shave off 10-20% in my experience, a properly written system can reduce it by 80%+

[sleek terrace]

i see

[flint geyser]

Can I have a class' value be tweekable in inspector without putting [SerializeField] in front of them? Perhaps with Odin?

[pure dock]

i believe you can switch the inspector to Debug mode . . .

not really a viable solution though . . .

[novel plinth]

you can with custom editor and with your custom classes be contained in a ScriptableSingleton and set it's filePath so the data will be persistent (assuming this for edit mode) if not for edit mode, then you'd need to store it somewhere which might end up using a serializer 😅
that's sorta weird use case you have there

[sleek terrace]

How can nothing be rendered and I still only have 130-ish fps?

just curious btw

[mortal gust]

Not coding, not advanced. You're either bottlenecked on either GPU or CPU side. Might be slow hardware, might be running computational expensive code in background.

[sly grove]

https://docs.unity3d.com/Manual/Profiler.html only this can answer your question.

[plucky laurel]

[ShowInInspector] with odin

[dusty wigeon]

Most likely because of editor code.

[shy glacier]

when i use Physics2D.Raycast are all RaycastHit2D properties computed, or just the ones i refer in code?

also, if so, instead of getting RaycastHit2D.distance, could i somehow get square distance instead, to not compute a square root operation?

[sly grove]

They're already computed by the time you see the struct. The properties are just straightforward passthroughs:
https://github.com/Unity-Technologies/UnityCsReference/blob/076ffb2c16d2aec23c2df1cb6cec03562186ec33/Modules/Physics2D/ScriptBindings/Physics2D.bindings.cs#L3167

[shy glacier]

ok, and is there anything i can do to speed up the process, or no?

[dusty wigeon]

You are doing micro optimization

[sly grove]

is there a reason you're asking this? Are you seeing a performance issue?

[shy glacier]

yes im truly am

[dusty wigeon]

Then, change to DOTS if it matters

Unity GameObject is not made for that.

[shy glacier]

yeah, i know, especially the fact that unity uses C# and doesnt let me treat bools like numbers and forcing me to use branches

if not the unity profiler, i'd propably be stitting in unreal rn

[tiny pewter]

i remember you can trun bool into int by something like
*(byte*)&bool

[dusty wigeon]

I really doubt that Unreal is better for that. Both engine are not made for hyper performant games.

[sleek terrace]

anyone know why combined mesh isnt working?

[shy glacier]

thats unsafe code, which needs extra enabling and messing with settings, not fo rme

[shy glacier]

unreal uses C++, which is already a win in performance

instead of creating a branch i can just do something like

void OnJump
{
  velocity += Vector3(0, jumpHeight * Isgrounded(), 0);
}

isgrounded is meant to be function that returns bool here

[sly grove]

ok but... are you wanting this because you are seeing performance issues or because you're an optimization junkie?

[shy glacier]

both

it is a little optimization and looks cleaner

well this is not the biggest example of C++ having better performance than C#

[sly grove]

you've tracked down a noticeable performance issue in your game to the fact that C# can't convert bools to ints without branches?

Kinda sems more like you just don't like it, which is fair

[shy glacier]

those are 2 different examples

[tiny pewter]

use unasfe code....

[shy glacier]

also i already dealt with it, i will use raycasthit2d.distance

[dusty wigeon]

First, it is not cleaner. Second, it is less performant.

[shy glacier]

no way

you are multipying by either 0 or 1

if this was a branch, then CPU could misspredict

[dusty wigeon]

You are multiplaying and adding every frame

[shy glacier]

not every, this is a function OnJump

[dusty wigeon]

Nvm, I see that you use OnJump

[tiny pewter]

switch(bool){
case true:break;
case false:break;
}

i try this and the compiler compile this.....
you may believe the compiler will generate jump table instead of cmp
though mispredict still happens

[dusty wigeon]

However, you are still doing addition for no reason

[shy glacier]

switch is also a branch

[dusty wigeon]

Branch is better here

[tiny pewter]

but for bool?a:b
branching is faster than a*bool|b*!bool in my machine

[shy glacier]

this is a ternary operator

its also a branch

[tiny pewter]

two multiplications cost more on my machine

idk if you have a fast multiplication unit in your cpu

[dusty wigeon]

You also have 3 additional addition (with his code)

[shy glacier]

ok rewrite the code without 3 additions

[dusty wigeon]

if(IsGrounded())
{
  velocity += new Vector3(0, jumpHeight, 0);
}

[shy glacier]

void OnJump
{
  velocity = new Vector3(velocity.x, velocity.y + jumpHeight * Isgrounded(), velocity.z);
}

only 1 addition now

[dusty wigeon]

Still one more than necessary

[shy glacier]

ok i got another point

in C# you cant give CPU hints

in C++ https://stackoverflow.com/questions/30130930/is-there-a-compiler-hint-for-gcc-to-force-branch-prediction-to-always-go-a-certa

[sleek terrace]

i dont see the point of arguing over c# vs c++

unity uses c#, nothing we can do about it

[shy glacier]

i know

its not arguing

its discussion

[sleek terrace]

its a pointless discussion

[dusty wigeon]

We all agree that C++ is better than C# for performance. Does not make Unreal suitable for performance junkies

[sleek terrace]

Was able to double fps by combining them

[sleek terrace]

Ive heard conflicting views on this,
is it true that towards the high end of performance, it really comes down to the individual programmers themselves?
what really differentiates unity/unreal is workflows

[dusty wigeon]

Neither of them has been made with performance as a priority

[sleek terrace]

how come?

[tiny pewter]

actually you may predict the c-code equivalent

  *(some address+some offset0)=*(some address+some offset0)
  *(some address+some offset1)=*(some address+some offset1)+some reg*return reg//i forgot what is called
  *(some address+some offset2)=*(some address+some offset2)
if(return reg){
  *(some address+some offset0)=*(some address+some offset0)
  *(some address+some offset1)=*(some address+some offset1)+some reg
  *(some address+some offset2)=*(some address+some offset2)
}

the compiler should ofc eliminate the first and third but you have to trust your compiler

[dusty wigeon]

Because, there is other priority such as Visual Quality, Flexibility, Compatibility, etc.

[shy glacier]

well i just thought so, because i saw way more AAA games made with unreal than unity

[dusty wigeon]

Visual Quality is higher with Unreal which attract bigger studio

[tiny pewter]

i always suggest before you doing some micro optimizations please ensure you have a good algorithm first by reading paper or copy and paste

[dusty wigeon]

It is also harder, which make smaller studio use Unity instead

[shy glacier]

i do this everytime

[sleek terrace]

making a game like gta easier with unreal than unity?

[shy glacier]

it would be easier with unity, but the game wouldnt look realistic, what imo is essential to GTA

[dusty wigeon]

For a bigger studio, you would want to use Unreal for it's better graphical capacities.
For a smaller studio, Unity will help you finish your project by being easier to work with.

[sleek terrace]

I see

[dapper pumice]

but you can have nearly similar grpahics in unity too

[sleek terrace]

what about maximzing performance? which one is easier?

[dapper pumice]

if you fully understand all the features hdrp provides.

[dusty wigeon]

Unfortunately, Unity is clearly worst than Unreal in this category.

[tiny pewter]

studying computer architecture and algorithm is easier

[dusty wigeon]

No idea, both has not been made for that. That being said, Unity has DOTS which is partially made for that.

[uneven mauve]

Just going back to where I was yesterday, how should I do storage for user builds? If a user places objects in the world on a grid, I'm using a dictionary for coordinates but no clue how to structure the c# scripts?

This is where I left off
#archived-code-advanced message

[tiny pewter]

the placing pile game?

[uneven mauve]

Pipes

Yeah

Well I got to here

[sleek terrace]

amazing

you got the right idea thus far

[uneven mauve]

I never established if I could use classes

I was told "classes bad, use classes"

Each pipe stores its neighbours and type

[sleek terrace]

you could use scriptable objects
which hold the object world position

[dusty wigeon]

Nobody said that class are bad. We just said that it is less performant.

[uneven mauve]

Ah right

What's the class substitute?

[dusty wigeon]

They are better in many more ways

[uneven mauve]

I'm totally new to Unity scripting

[dusty wigeon]

struct

[uneven mauve]

Ok, I'll have a quick read on them

struct Coordinate
{
    public int x;
    public int y;
}

Like that?

Basically a class but no functions

[tiny pewter]

the struct should consists of coordinate, type and neighbor which represented by four bits
struct can have methods

[uneven mauve]

When storing pipe health, I was considering a class because then a function could "damage" the pipe

[uneven mauve]

I've got the enum down! Good bit of learning, interesting!

For the struct, I'd just have an external function to "damage" a specific coordinate

So each item doesn't have the same bit of code

brb

[tiny pewter]

if the number of type<=16 you can even bitmask it into the one byte with neighbors
the sturct should look like
x,y,a byte, and you have 24 padding bits left......

[sleek terrace]

after doing mesh combining and with dynamic batching on
does anyone know if I can get better FPS than this?

[sly grove]

most of your issue is on the CPU side now

so - open the profiler and see what's up. I bet a lot of it is editor overhead

[sleek terrace]

but I generated the mesh once?

[sly grove]

don't guess

profile

[sleek terrace]

others is taking up all my performance

[dusty wigeon]

Others is usally the editor

[sly grove]

yeah try a build

[sleek terrace]

editor loop is taking up all my time

[dusty wigeon]

Yes, this is why you profile a build and not the editor

[uneven mauve]

Sorry for the delay. I'm back. So I assume I create a struct for the components, then load each one from storage? idk much about storage yet so I'll research that. When the player places a pipe, I just create a new struct and add it to the dictionary?

[tiny pewter]

what is from storage? disk?
yes create a new struct then assign it to dictionary if user places a pipe

[sleek terrace]

Still only hittin 250

[dusty wigeon]

Way better than what you had before

At the moment, your issue is that you are running a development build

Which is slower

If you want real FPS data, you need to make a release build and print the FPS.

Or use native tooling

[sleek terrace]

how did u know it was dev build?

[dusty wigeon]

You cant profile a release build

A development build adds the necessary code to profile which make things slower.

[sleek terrace]

ok

but still even in editor mode, should I be getting higher fps?

[dusty wigeon]

No.

[sleek terrace]

https://www.youtube.com/watch?v=6mNj3M1il_c

[dusty wigeon]

It depends of a lot of things

I'm not even sure if he is in the editor

[uneven mauve]

Save Data i guess, when the user has saves of the game

Or am I too early on for that?

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

[System.Serializable]
public struct Component
{

    public enum ComponentConnections
    {
        None = 0,
        North = 1,
        East = 2,
        South = 4,
        West = 8,
    }

    public string type;
    public int health;
    public int pressure;
    public ComponentConnections neighbors;
}

public class ComponentManager : MonoBehaviour
{

    private Dictionary<Vector2Int, Component> ComponentDictionary = new Dictionary<Vector2Int, Component>();

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

I currently have this but I'm struggling with the key. Each pipe is 3x3 unity coordinate units, but I'm technically calling it 1x1 on my internals for ease. Should I still do Vector2 (1, 1) even though in scene space it would be (3, 3)

To get the actual location of the component, multiply coordinates by 3

[dusty wigeon]

You should dissociate the visual from the data

So yes

[uneven mauve]

Right so the key will be 1, 1 and scenespace will be 3,3

Thanks

So "start" function should be where it loads components from save data to the dictionary

[dusty wigeon]

That would be a start

At this point, you just need to get somthing working.

[uneven mauve]

Yeah totally

[tiny pewter]

you should use a int or byte to represent neighbors since you may have multiple neighbors

[uneven mauve]

I've been fully thinking about theory for performance all day

[dusty wigeon]

Usually you do:

1. Work
2. Clean
3. Optimize

[uneven mauve]

Ah right

I was a little cautious on this as it's hard to optimize if I totally go the wrong way

[tiny pewter]

eg if some tile has east and north then neighbor=East|North

[dusty wigeon]

This is why you have short iteration.

[uneven mauve]

Surely that's handled by enum?

It'll return 0-8

[tiny pewter]

no

is 0-15 actually from 0b0000 to ob1111

[uneven mauve]

Oh right I missed a digit

So the current enum format is wrong?

[tiny pewter]

no, but the way than how you store the neighbors, you should not use enum as its type

[uneven mauve]

oh

I'm totally lost then

Surely its in that format to allow easy conversions back and forth while only being 4 bits

[dusty wigeon]

You can add value in your enum:

    public enum ComponentConnections
    {
        None = 0,
        North = 1,
        East = 2,
        NorthEast = North | East, 
        South = 4,
        West = 8,
    }

[uneven mauve]

This is even more confusing, surely north and east would just be 3?

[dusty wigeon]

Yes, it is.

[uneven mauve]

oh

Right no I only need to do the main 4 directions

No diagonals matter

[dusty wigeon]

I mean, in your situation it would means that there is a connection North AND East

[uneven mauve]

Right, but doesn't enum just handle that by adding the numbers from directions passed in?

[dusty wigeon]

Yes.

[uneven mauve]

So why do the math twice

[dusty wigeon]

To have a meaning

[tiny pewter]

you will have 16 values if you do that in this way....just bitwise or them it directly assign will override the neighbors tile has

[uneven mauve]

16 values is good no?

That's the lowest it could be?

It can have upto 4 connections from any direction, potentially 0

[tiny pewter]

eg if there is a new tile in north then tile.neighbors|=(int)enum.north

[uneven mauve]

If there's a new tile to the north, add 1

[dusty wigeon]

Yes and no

[dusty wigeon]

Read https://learn.microsoft.com/en-us/dotnet/api/system.flagsattribute?view=net-7.0

[tiny pewter]

let start with the basic
normally you will use four bool to store if there is neighbor in given direction
eg northExists=true/false
now you need 4 bytes to store them but they are just 1 (true) or 0(false)
so you now use a bit vector of 4 bits to store them

[uneven mauve]

Right

[daring spire]

does anyone know how to get started on coding this effect? (i dont rly know what to search on google either so any link will be appreciated 🙏 )

[sleek terrace]

2 cameras

with culling?

hell, you can actually render both images far apart

and simply move the player and camera accordingly

[daring spire]

oo thanks! to switch between them would u use a collider at the door or for the whole inside part of the room?

[sleek terrace]

yea

[sleek terrace]

use a collider inside and outside the house

[uneven mauve]

So how do I apply this then? I thought this was the enum

[sleek terrace]

when the user collider is hit and u have determined the user wants to exit,
load the outside image immediately, move camera and player around
then disable image 1, enable image 2,

from the player POV, it will look seamless

[daring spire]

gotcha! so you're just teleporting the player to some random far away location with that room and teleporting them back afterwards?

[sleek terrace]

yea

it doesnt have to be far away

but all your really doing is enabling and displaying images

the reason you might want the interior far away is because of colliders

so what I did was that, I would spawn the interior far away where I was sure there were no colliders or anything of the sort

then when the user spawned back in, I placed him in the original world map

[daring spire]

ahh ok but i think my issue is the scene has some game objects that i cant disable (persistant logic on them)

thanks for the input! ill get working on it 👷

[sleek terrace]

in that case, spawn the interior away from the main game area, place user in said area ... boom!

all other objects will still be visible and rendered, but player wont know it

[tiny pewter]

I have to sleep now,
Since enum not allow you to store other value and the enum is just for helping you to set different bit in your bit vector ie the byte that storing neighbours exists or not

[harsh canyon]

sleep is for the weak

[bleak citrus]

this is how to not make a game (:

I think a healthier approach is to get something working, and then spend all day thinking about how you'd change it

Not too much, or you'll wind up a huge sunk cost

You need some context to make those tougher choices

I'm doing that right now with my largest project. I'm making some big design changes informed by headaches I had

[brisk spruce]

Eh I mean, its all about striking the balance.

You also dont wanna just start throwing stuff at the wall and building on top of a bunch of poorly designed code.

Finding the right balance between Tech Debt and Over Optimization is honestly one of the most important skills in development, and its a skill that you just always keep honing for literally your entire life

[harsh canyon]

game development is so depressing

[bleak citrus]

better to run than curse the road

[harsh canyon]

humans arent meant to sit behind computers all day

[harsh canyon]

too late for running

[brisk spruce]

instructions unclear, sitting on top of my computer now D:

[bleak citrus]

i spent an hour in a chair for the first time in like a week today

i didn't like it

moving around frequently makes things a lot nicer

[harsh canyon]

yeah but you wont get anything done

[brisk spruce]

Aight so, I have a bunch of logic that effectively has the job of constructing one "round" worth of actions for all entities in the scene.

I need to normalize their animation times however, so I am facing two options and I am not sure which one is going to be easier to maintain vs better performing.

Effectively my struct is a RoundAction, so I have a List/array/whatever of em.

public struct RoundAction
{
    public ActionType ActionType { get; }
    public Direction Direction { get; }
    public Vector2Int Target { get; }
    public float Time { get; }
}

Option one: now that I have all the actions times, I go through and mutate all their times to normalize them, this makes it though that my RoundActions are now mutable and not readonly

Option two: I create a new list of structs, copying the data over, but whats important is I can have 2 seperate types of structs, such that the returned struct only has the necessary data I need for the time calculations and then the output struct has potentially other stuff on it I may need, keeping the "calculate" vs "actual" structs as 2 distinct structs that may diverge over time cuz they might need to have different stuff on em

Option two is definitely crazy wrong right? Im overthinking this one and should just make it the struct mutable?

[uneven mauve]

I'm getting an error with this:

[Flags]
public enum ComponentConnections : byte
{
    None = 0,
    North = 1,
    East = 2,
    South = 4,
    West = 8,
}

The type or namespace name 'FlagsAttribute' could not be found

[fresh salmon]

System.Flags as it's not using System; by default in Unity
And hello again!

[uneven mauve]

ah

hey

haha

ty lol

Moved back over as I was moving from general editor to actual unity

[brisk spruce]

can make it a bit easier maintain by using bit shifting

[Flags]
public enum ComponentConnections : byte
{
    None = 0,
    North = 1 << 0,
    East =  1 << 1,
    South = 1 << 2,
    West = 1 << 3,
    All = (1 << 4)-1
}

[fresh salmon]

Beginner, slow down (source: posted in another server)

The numbers symbols Mason, what do they mean?

[brisk spruce]

Hey if its posted in #archived-code-advanced Im gonna give advanced advice :p

[uneven mauve]

There was more of a gap than expected jumping from standard programming like websites and apps into C# games

Js is great, I'm not totally familliar with C# but it's a similar programming concept

The logical thinking also carries over

But gotta keep performance in mind now

[brisk spruce]

I think js has the same operator for bit shifting IIRC

[uneven mauve]

Yeah

[fresh salmon]

Unity used to support JS, that's probably where we got the Geneva-convention-breaking naming of everything in Unity

[brisk spruce]

and yeah it can be nice to include an "All" flag at the bottom for your flags for easy of checking

[uneven mauve]

Well UnityScript was still very far from JS

[uneven mauve]

Ah right I see, ty

[uneven mauve]

Moving on to the next issue, after the user has placed a ton of pipes and they are in the dictionary, there's a system to manage internal pipe pressure. I have an idea on how to do it but idk if it would be bad for performance.

My initial idea was every update, check each pipe for pressure less than 100 but greater than 0 (100 would be the default). If a pipe is in that range, take the neighbour and also set it's pressure to that amount. This would then be like a waterfall effect through the entire pipe system

[sleek terrace]

Is it possible to combine meshes that use thesame material, but each mesh may use a different texture?

My hexes all use thesame material, but i use the material property block to change the texture, however, it seems when i later on combine these hexes into 1 mesh, they all share thesame mesh

[stuck plinth]

you could put all the hexes with each texture in their own submesh, then you could fill up the materials array on the renderer with your material and set a different property block at each material index?

[sleek terrace]

hmm

[sleek terrace]

I like this idea, however, I want to have the freedom to individually change each hex, as I see fit

With your method, I would have to rerender the entire mesh grid wouldnt i?

[devout coyote]

I'd advise you to build a proper graph structure that you can easily traverse instead of plonking everything into a dictionary

But honestly it depends on how many pieps

100? 1000? 10.000?

[uneven mauve]

Well they can build as much as they like, but for their best chance to "succeed" at the game, they'll ideally not want more than 50 "connected"

[devout coyote]

Suggest looking into graph theory and specifically connected components

[uneven mauve]

I was discussing the best storage method earlier and it was the best starting point to optimize later if needed

[devout coyote]

Build it

See if it's fast enough

Only optimize if you know you need to

[uneven mauve]

Well I don't know how to do the pressure to test

I don't know if that pressure check should go in the update function, or some other method

[devout coyote]

I'd update it once you place the piece

Register it as part of a whole

And then once the whole changes update the whole

Or just chuck it all in update

Really depends on the amount of game objects

50 shouldn't be a problem

If you think about it, it doesn't matter where the code goes

[uneven mauve]

I'm totally lost. I don't know how to "spread" the pressure. If one pipe has a leak, how does it join to the other neighbour pipes

[devout coyote]

Just move it to a seperate method if update is too sloe

[uneven mauve]

I was doing the "waterfall" idea but that might be bad

[devout coyote]

Waterfall is fine

It's a basic way to traverse a graph

Again, look up graph theory, connected components is what you are looking for

[uneven mauve]

So if neighbour pressure isn't the same as current pressure, I average the values for both?

[devout coyote]

If that's the behaviour that you want

[stuck plinth]

yeah, if you need to update individual hexes a lot without each one being an individual mesh, you need some other way of identifying which texture to use at each coordinate... maybe you could pass a separate buffer of that info to the shader or something like that?

[uneven mauve]

Well if one has a hole, I want the entire section to copy its pressure

[devout coyote]

So

You need to find which nodes (pipe pieces) that are connected (have edges)

[uneven mauve]

Yeah, that makes sense

I could treat this as "this is a list of every connected component" but I feel like there is a more proceedural method

I heard about BFS and DFS algorithms

[devout coyote]

Good starting point

[uneven mauve]

I'm just going to implement waterfall for now maybe

It's easiest and no issues can occur

[devout coyote]

Your waterfall method is DFS or bfs

Depends on how you implement it really

[uneven mauve]

Well I didn't think that far

It's just, every update, check if a pipe has pressure that isn't 100. If that pipe isn't 100, check if it has neighbours. If those neighbours don't have the same pressure, change the pressure to something

[devout coyote]

That won't work

[uneven mauve]

For performance?

[devout coyote]

You don't control update order

Say you have 100 and 99

Should 100 become 99 or 99 become 100?

[uneven mauve]

Right yeah that's why I said "something". I could either set it to an average of both, so 90 and 100 would make both 95

That then allows simulation of larger areas to lose pressure slower

So then if a pipe has pressure 100, the others will fill

[devout coyote]

Okay but then the next pipe is at 85m

[uneven mauve]

In what order?

[devout coyote]

Does it do 90 - 85 or 95 - 85?

[uneven mauve]

No clue honestly

One issue I face is that pipe valves can be opened and closed (Not en mass hopefully) but this could impact sudden changes

[devout coyote]

Yeah so you can't compute it just based in the neighbours

You are going to have to use proper graph algorithms

[uneven mauve]

Wow that's hard i see

ty

I'll investigate and not panic

Do you think DFS or BFS given this concept?

I'm thinking BFS

[dusty wigeon]

BFS makes more sense.

[uneven mauve]

I don't even know how I would pass in the data needed

I don't even have anything set up to test on, like default pipes

[desert ember]

Ive got this problem going on with my car shooting, heres a clip of it. for some reason when i turn at a certain angle it decides to shoot backwards instead of at the point I want, i have a plane that uses the same script and it has no problems, any advice?

[sleek terrace]

send code soldier

[desert ember]

https://gdl.space/secitobofe.cs

thats what ive got so far for the shooting

[sleek terrace]

have you identified that the mouse position in within the confines of the game?

[sleek terrace]

s

[desert ember]

now you sir, have sparked a new idea in my brain. thank you

[sleek terrace]

your welcome, Im guessing as you are moving the scene around with your mouse, your mouse position is changing, causing the ray to shoot of in a different direction

[jolly token]

I wouldn't say option 2 is wrong. It is natural to separate runtime data from immutable design data.

[brisk spruce]

at the moment I am using the same type for both, but I ended up going with adding this method to my struct:

public RoundAction TimeScale(float multiplier)
{
    if (Math.Abs(multiplier - 1.0f) < 0.01f)
    {
        return this;
    }

    return new RoundAction(ActionType, Direction, Target, MinTime * multiplier);
}

lets me still keep it sort of compartmentalized away but keeps the struct as a readonly one

[jolly token]

If record struct was in Unity you could do 😛

return this with { Time = MinTime * multiplier };

Anyways I think that is alright

That's what custom numeric types usually do

[desert ember]

tried making an object that would go where the mouse does but that seems to be working, it almost looks like the guns are shooting at the camera when its acting weird

[sleek terrace]

Im not sure what you are trying to say

[trail cedar]

Hello, I've been working on the project for a few weeks now, and I'm having a memory issue. I'm taking a snapshot of the device, but I'm unsure what's consuming the rest of the memory. Does anyone have an idea on how to identify the cause of the problem? Thank you in advance for your response.

[flint sage]

You should probably look in the other memory profiler tabs

[trail cedar]

Could you explain what you mean? I've looked through other tabs, but the memory breakdown is not available in this version of Unity, and in the tree map I still can't find the cause of the problem. It doesn't seem like anything from the tree map is causing such a significant consumption, but as you can see, most of it is taken up by native memory, executable dll, and untracked, which I don't know where they come from and how to reduce them.

[flint sage]

Well you've got 330mb of meshes

160mb of textures

[trail cedar]

I know that and I can't reduced it anymore

As you can observe, the tree map is only utilizing 1.3GB, while the entire game is consuming 3.6GB. Therefore, my question is, how can we reduce the remaining 2.3GB of memory usage?

[clever urchin]

Is this a build with development mode turned on or in the editor?

Because the editor is super unreliable (textures, meshes, etc being double the size for one)

[trail cedar]

Development build

[clever urchin]

Do you create textures on the fly in script?

Try marking them as read only, should halve the RAM usage per texture if you're not needing to read/write the pixel data

Try benchmarking before and after a Resources.UnloadUnusedAssets call as well to see if you have some native memory leaks

I love this sort of optimization stuff, I recently optimized the hell out of our app at work

[trail cedar]

Snap shot is created after level loading and Resources.UnloadUnusedAssets function

[clever urchin]

Ok you'll need to look into the lifecycle of your objects then

Can you screenshot the other tab with the bars in it?

Should be light blue, dark blue, yellow, etc horizontal bars

Unfortunately Unity's garbage collector is absolutely horrific and quite frankly needs urgent work on it

So you might have fragmentation issues, or reserving a lot of pages

[trail cedar]

Do you mean Memory usage overview or someting else?

[clever urchin]

Other view

"Summary"

That one shows a dcent amount of memory fragmentation

[trail cedar]

How can I fix memory fragmentation?

[clever urchin]

Reuse objects, don't create short lived objects often

Unity is terrible with fragmented memory because it uses a non generational, non compacting garbage collector

You do have 600 mb of native memory thats sort of just chilling unused but reserved

Managed C# memory looks fineish apart from a bit of fragmentation

Are you loading a ton of large amount of unity objects or some large ones and then unloading them?

Asset bundles perhaps or addressables?

[trail cedar]

Yes we are using World Streamer asset for loading/unloading chunks of open world

[clever urchin]

hmm

[trail cedar]

We are not using those

[clever urchin]

Without knowing exactly how your code is laid out, and whether that asset reuses the memory it loads/unloads its hard to tell

But putting in some guess UnloadUnusedAssets calls at certain points and comparing snapshots might help

Look up how to compare snapshots

[trail cedar]

Is it way to find out other reserved memory?

[clever urchin]

Unfortunately Unity handles it all in a black box

They're hard to track down

But native is Unity's own memory for the engine

[trail cedar]

If I understand correctly, there is no simple way to solve this issue, and I need to manually search for the problem in the code, right?

[clever urchin]

Yes, no quick fix unfortunately

I would 100% do some comparisons between two memory snapshots

When you load one chunk for instance, then load and unload a chunk and see what happens

Then do a few other things like that

[trail cedar]

I will definetly try it. Thank you very much for your help

[soft shoal]

About this memory fragment, I come up a thought. I've heard that C# GC provided by .NetFramework will release unused obj and compress the rest memory to remove those fragment. So in Unity it doesn't work this way based on what u r saying, I guess this is because Unity uses Mono or IL2CPP? Is that right?

[soft shoal]

@clever urchin And for this, do you have any idea what this untracked memory can be? like why it happens? Here it's 480 MB, quite a lot.

[soft shoal]

@trail cedar For this, I guess all kinds of plugins and built-in packages can contribute.

[trail cedar]

I don't have much of this kind of stuff, but the World Streamer asset definitely takes a significant chunk of it.

[clever urchin]

Not 100% sure what that could be

[clever urchin]

Not necessarily, the actual C# garbage collector is a well oiled machine with a ton of complex parts. Sometimes it does compact, most of the time it doesn't.

Unity on the other hand does not use the same garbage collector, they use this gc https://www.hboehm.info/gc/

The actual C# gc is generational, and splits up into chunks depending on how long the object has lived, and the size of it whereas Unity doesnt do any of that

So it's much less efficient from that regard

[lofty solstice]

Anyone here happen to know if unity meshes use shared vertices or not?

[clever urchin]

Across one mesh or multiple?

[lofty solstice]

One mesh

[clever urchin]

Yeah they can share verts

[lofty solstice]

aight, thanks!

[dusty wigeon]

Pretty sure it is expected to have that much memory untracked.

Here is a snapshot of the memory distribution of our game

Also, you should use 2022 to analyze your snapshot

It can open older snapshot

Fragmentation will most of the time get to 50%. At least in the managed memory

Finding leak is pretty easy with 2022. Here an example of a leak we found:

[plucky laurel]

what really differentiates performance is not language or engine, its the concepts and algorithms and how they are utilized

just look at DLSS which made conceptual shift is optimization

same thing for any low level code, a small change in how algorithm approaches a problem can gain orders of magnitude performance

or a massive shift from one paradigm to another, like OOP > ECS

when approaching any problem one needs to understand the domain of the problem and requirements, what are the budgets placed, there is no point in sweating over a problem if the performance is simply not required or lies within the budget

[molten socket]

Does anyone have experience with OpenFracture?

It just does not fracture my custom meshes no matter what

What have I done wrong..?

[valid tapir]

Is there really no way of getting single MeshData from Mesh? I need to create custom NativeList of MeshData but I can only retrieve MeshDataArray. Getting first element would be okay but the problem is now the array stays in the memory and when disposed it will dispose of the copy you get for custom NativeList.

[stoic python]

Hoi people! I'm trying to capture video clips out of a built windows app, something like scripted recorder from the recorder package (which only works in edit mode)

What are my options?

[flint geyser]

In Zenject when a Context appears, when is it installed? Can't find Awake or Start in it

When creating an object with Zenject, how to pass to it some data before the installers work?

[misty walrus]

before the installers work?
By installers do you mean before the injection occurs?

[flint geyser]

Yep

I want the injection to depend on something I pass

[misty walrus]

Have you tried creating the object from a method?

[flint geyser]

Without Zenject it won't do

[misty walrus]

Container.Bind<Foo>().FromMethod(GetFoo);

[flint geyser]

Without injection I mean

[misty walrus]

I meant like so.

[flint geyser]

I have packs with cards which are meant to spit cards when clicked upon, so installers on cards won't have access to the method

Cards are meant to be created following a template and I want to pass the template somehow

[misty walrus]

Any reason a factory would not be suitable for this?

[flint geyser]

I mean I AM using a factory

For instantiating the cards

But I can't figure out how to give created cards the template before their installer works

[misty walrus]

    public class Factory : PlaceholderFactory<float, Enemy>
    {
    }

I haven't used Zenject in a long time but it looks like you can pass in arguments like so. In this example first argument is passed in.

You can pass the template as an argument, that you can then use in the constructor if the Card class

Hello, I am attempting to add some files to my Project. I had errors with Namespaces before referencing the new Assembly Definition with the "master" one as shown in the image. This solved those missing file errors. However, I now receieve the errors shown in the image too and I can't figure out why they are errors and not warnings :/

[sly grove]

1. Namespaces are not relevant to assembly definitions at all. Only Assemblies matter
2. those errors have nothign to do with assemblies

honestly they seem like they should be warnings, not sure why they're errors

[hybrid belfry]

I see thanks

I can get around it using #pragma warning disable 414 but this is for warnings not errors but resolves the issue haha?

Odd

[light hamlet]

is there a way to apply materials to TMP_Text? I want the color of all the text in my game to match a material color so I don't have to change all the text at the start of every scene

[sleek marsh]

when someone says "compute shaders are faster than multithreading" is the reason just because gpus have more cores than a cpu?

[sly grove]

I would say that whoever said "compute shaders are faster than multithreading" is confused because compute shaders are an example of multithreading.

[sleek terrace]

multi threading on gpu faster than MT on cpu, no?

[sly grove]

a GPU generally has overall more "computing power" than a CPU when measured in terms of like... total operations per second.

"faster" is a very loaded/vague term

[sleek terrace]

you know what I mean

@sly grove is helping people on unity your job? your always here

[sly grove]

for certain embarassingly parallel use cases (rendering a scene, doing per-pixel texture operations, etc) the GPU can generally do it much faster than a CPU

[sly grove]

still waiting for my paycheck

[sleek terrace]

lmao

I want to get 1000fps out of this

thoughts?

its just a bunch of hex meshes which are their down objects

combining only doubles the fps and I want to be able ot access them individually

[tired fog]

Is there any way to check how big (size in bytes) a compute buffer is?

[tired fog]

transfrom it into a gpu instanced objects, so no gameobjects

[brisk spruce]

You'll want logic to stop accessing individually and lower the resolution when you zoom out prolly

Combine like radius of 5 hexes into one big hex at a certain zoom, then do it again at even farther zoom

[sleek terrace]

I want each hex to be modifiable

[sly grove]

https://docs.unity3d.com/ScriptReference/ComputeBuffer-count.html
multiplied by
https://docs.unity3d.com/ScriptReference/ComputeBuffer-stride.html

[tired fog]

mmmm, okay

[brisk spruce]

How can they modify something they can't even click on at a large enough zoom out?

[sleek terrace]

O, I see what you mean

[brisk spruce]

Your hexes look less than 1 pixel big on your bottom pic

[sleek terrace]

thats just so I can render all of them to test true fps

lets not worry about that

[brisk spruce]

Oh well, depends on your actual goal then. I'd start by testing rendering at an appropriate zoom

[sleek terrace]

so as long as all the hexes are on the camera, it will render all of them

with same fps

[sleek terrace]

I will try this

[plucky trellis]

If that doesn't give enough control, try generating a mesh for chunks of hexes as a combined mesh, and update the mesh as needed when chunks change

[torpid smelt]

Hello. I'm attempting to load a JPG into a texture2d, however, the size of the JPG is far too big and needs to get downscaled. is there a sane way to do this in Unity? I've looked around but couldn't find any solid resources about it

[urban trellis]

you'll probably need to load/decompress it to pixel data manually, then do the downscaling, then load it into the texture2d

[sleek terrace]

even that is too slow

only 120 fps at 1.9m vertices

[stuck plinth]

something like bilinear sampling is pretty simple to implement, loading it into a texture and manipulating the pixels should be ok, it's basically just in an array until you call Apply after all

oops, that was meant to be a reply to @torpid smelt

[torpid smelt]

Annoying, but thanks. I'll look into it at a later date 👍

[plucky trellis]

That is pretty slow. Are you generating that mesh every frame perchance? That would slow things down significantly

[sleek terrace]

What does the instance array do?

[sleek terrace]

nope generated once,

[sage radish]

It's explained on the page, if you scroll down a bit.

[sleek terrace]

why is it a list tho?

[sly grove]

presumably one for each instance?

[sleek terrace]

so it says...

hmm it sames all my instances have thesame position...

[sly grove]

your shader would need to take the instance id into account in order to position the meshes

[sleek terrace]

hmmm

how?

😦

[sly grove]

The passed instanceData can either be an array of Matrix4x4 (object-to-world transformation per instance) or a custom data structure

it's almost like the docs talk about it

[sly grove]

actually it looks like in this case it will handle it without a custom shader possibly?
I'm more familiar with Graphics.DrawMeshInstancedIndirect

which does require a custom shader

[sleek terrace]

thats the only mention of shader

[uneven mauve]

So I was looking at algorithms such as DFS and BFS. I have a player-built pipe system where they can layout a network of pipes. They are in a grid pattern where one pipe section is 1x1 and can have upto 4 connected neighbours. I need a function that given a coordinate of a pipe, list all connected pipes in that area to manage internal pressure. I am not sure if BFS is best, or if I should just recursively list all neighbours of that pipe, then search those neighbours and so on till no more are found?

[tall ferry]

bfs and dfs are methods to search through a graph, which you can use to list out all connected pipes. The only difference is the order in which they search through

[uneven mauve]

And it wouldn't be more efficient to just check the neighbours of the pipe I want to find links for? Not the entire thing

[tall ferry]

well i dont really know what you're checking for tbh, or how these things are even linked. Its not like dfs/bfs is some super unoptimized algorithm, its quite literally just different methods of going through a graph.
It sounds like you want BFS though since that will get everything directly related to the current pipe, then search out more from each neighbour if it didnt find anything

what youve described

recursively list all neighbours of that pipe, then search those neighbours and so on till no more are found
is quite literally BFS

except you dont have to use recursion, you can use a queue or whatever other implementation you desire

[uneven mauve]

Ah ty maybe I need to just do a bit of reading

[uneven mauve]

ty yeah this is exactly what I was describing lol. Got totally lost. Now to implement!

[uneven mauve]

I'm still a little stuck on how to feed in my data. All the examples already have all the nodes that are connected in a list. My system is the initial node which has the coordinates of its neighbours. Where would I make changes to get it to work?

[tall ferry]

does it only have the coordinates of its neighbour? or do you have a reference to the actual object

[uneven mauve]

I just reference the direction of all of the pipe's connections

Such as up, down, left, right

[tall ferry]

for an actual graph, you'll want the reference to the actual pipe stored. otherwise im not sure how you'll really reference another pipe

[uneven mauve]

They have coordinates in a dictionary so it knows its own coordiantes and can easily work out what's to the left or right

From what I guess:

• Take the current pipe and add it to the queue. Add it to the connected list. Add its neighbours to the queue. Repeat

[tall ferry]

im slightly confused from what you have stored because you said it was the coordinates of its neighbours. If you're storing a pipe itself in some variables called up, down, left, right, then yea you would just add those to the queue. The coordinates of it dont actually matter

[uneven mauve]

alr ty

[tall ferry]

https://dotnetfiddle.net/ktEoj5
just wrote a quick example if you wanted to see. i just hardcoded some connections so the connections itself fully doesnt make sense but you can see how it works.

                else if(ComponentDictionary[element].Neighbors.HasFlag(ComponentConnections.West))
                    queue.Enqueue(element + new Vector2Int(-1, 0));
            }

        }
        Debug.Log("CONNECTED:  " + connected.Count);
    }

I ended up with this but have an issue when trying to modify the current coordinate to get the neighbour. These are the errors :

[austere jewel]

why is object involved here?

[thin mesa]

use the generic Queue<T> not the non-generic one that stores things as object

[austere jewel]

Ah I see it now, I thought it was from ComponentDictionary or something I couldn't see

[thin mesa]

also HashSet.Add returns a bool, so you don't need to do the Contains check then add it, just if(contained.Add(element)) { //do shit }

[uneven mauve]

Probably the wrong place Queue<T> queue = new Queue<T>();

[thin mesa]

why are you in the advanced channel if you don't know how to use a generic class

[austere jewel]

Why are you sending screenshots of your console, is your IDE not configured?

[uneven mauve]

No

[austere jewel]

No, as in not configured?

[uneven mauve]

Because the original topic was advanced and I'm following on

[uneven mauve]

So where did I go wrong?

[austere jewel]

C# Queue and configure your IDE if it's not configured

[frank peak]

hmm so if Im working on a terminal based programming game but wanna store some representation of the in-game computers file system, as well as other devices (again, in-game). Does XML seem like an alright choice lol? It sort of suits the hierarchical nature of a file system, and for other devices it works more like a single layer deep definition

just as a way to save data I guess

[sly grove]

xml is awful

[frank peak]

lmao

[sly grove]

why not JSON?

[frank peak]

the syntax feels so cursed to me but im just unfamiliar with it

but it might be better

[sly grove]

it's much simpler, and also faster to parse

[frank peak]

hmm i see

part of me wants to do it in csv and then write a custom parser but i might also have to adjust the format by having a specific encoding for certain objects just to parse it lol

but itd probably be slower than what i have now, and def slower than json

[sly grove]

why write a custom parser?

[frank peak]

idk

fun i guess

[sly grove]

also why would CSV be good for a filesystem?

[frank peak]

it seems like it could be easy to store records of some abritrary content if i agreed to encode them in specific ways. like every 10 elements is a row or smth, and then from there on I could build substructures? maybe its more work than its work 😓

ill try json

[sly grove]

that sounds awful

all kinds of weird undocumented black magic

[frank peak]

i do want it to be obscure so that its harder to cheat the game hehe

assuming someone was looking at decompiled code or smth

[sly grove]

what does the file format of this save data have to do with decompilation?

[nimble nest]

A little philosophical question...
Assuming that I have 2 classes, e.g. Player and EnemyProjectile. In which class I should handle collision between this 2 objects - Player or EnemyProjectile? Is there a right way of doing this?

[sly grove]

there's no right way of doing it. It depends on the particulars of your game

additionally, it's not a binary choice. There are parts of that interaction that might be handled by the bullet, and parts that might be handled by a script on the player

it's not necessarily one or the other

[sage radish]

An archive file format like tar or zip would be more suitable for storing a representation of a file system.

Zip comes with the added benefit of per-file compression and encryption, but those two will also make reading and writing slower and memory intensive.

[frank peak]

makes sense, fair bit to think about i guess

and yeah archives eh

[brisk spruce]

How granular do you need? Recreating a fake Linux enviro? What sorta commands/files need support?

I would use Protobuf personally for fast serialization, though you really wand lazy loading of data tbh so perhaps a proper sql DB

You don't want to have to load anything greedy, just load stuff lazy at last possible minute

Could use a proto set to define the hierarchy as a bin file, and raw "text" files are all stored in a text file with id numbers per text block.

[frank peak]

👍

sounds good to me tbh

[eternal frigate]

Is it possible to manually add it to an abilities List and set the values?

[System.Serializable]
public class PunchAbility : ActionAbility {
public float punchPower = 10f;

    public override void PerformAction(params object[] parameters) {
        if (parameters.Length > 0 && parameters[0] is bool shouldPunch) {
            if (shouldPunch) {
                if (parameters.Length > 1 && parameters[1] is GameObject target) {
                    Debug.Log("Punch with power: " + punchPower.ToString() + " at target: " + target.name);
                    // Implement your punch logic here using 'punchPower' and 'target'
                }
            }
        }
    }
}

[flint sage]

Make what editable

Maybe serializereference

[eternal frigate]

Nevermind ChatGPT rules xD

[eternal frigate]

thanks 😉

[tough ibex]

hey guys, is there a way I can change the "names" of the objects that show up in the object selector? I have a bunch of scriptable objects that come from the same filename (see screenshot) and as my game grows, I find it'll be difficult to scale this, given that I currently have to click and search through each one to find the one I want. I can't even search since the search bar doesn't filter the path of the object

like presumably it's just taking that name from the meta.character filename

[flint sage]

CAn't you just change the file name?

It shows the path at the bottom iirc but yeah it's annoying

[tough ibex]

the files come from an external program that uses the meta.character to get info about the character, since the folder contains other things like portraits and other assets

so I'd prefer if I can keep the file name

[flint sage]

Ah 😬

[misty walrus]

You can write a custom property drawer that displays a popup where you can name them?

[tough ibex]

yeah but I'm trying to figure out how to name them

[flint sage]

Or a custom editor that automatically assigns the meta data as I'm assuming there's a main character file you're also selected?

[misty walrus]

Ah sorry I thought you just wanted the names to show up differently in that object selection window, not to rename them.

[misty walrus]

wait

[tough ibex]

I think I am? like, say these characters are called "jen", "jack", "john", "jade" etc, then I'd want those names to be there instead of "meta", "meta", "meta", "meta"

[tough ibex]

but I don't see how a custom property drawer would help me. I'm just trying to figure out how I can set my own names for the objects in code

[flint sage]

I guess theoretically you can write a project view extension that loads the file and draws the new filename on top

[tough ibex]

well I tried diving into the Unity decomp to find where they render the name, but it's a labrynth

I won't spend too much time on this, I was more just wondering if there's a utility

I found ObjectNames.SetNameSmart but that doesn't seem to have helped

[flint sage]

There's https://docs.unity3d.com/ScriptReference/EditorApplication-projectWindowItemOnGUI.html

That then lets you load the file and do magic to draw a new name on top

[tough ibex]

I'll check that out

[misty walrus]

Is the linked object going to be shown in the inspector apart from the object property field?

[flint sage]

Definitely a hacky way though

[tough ibex]

only here

[misty walrus]

Then I would suggest, for an easier way, to write a small custom property drawer. Then use EditorGUI.Popup where you can name them.

This is probably just as hacky though. It should however be around a 20~ line solution.

[stuck plinth]

is this asset imported by some plugin's importer that you don't have the ability to change? it should be up to the importer to set a proper name

[tough ibex]

I have access to the scripted importer just fine, but I'm not sure how to set that proper name

[tough ibex]

This would just help for the inspector appearance though right?

I guess along with Navi's solution it would work

[stuck plinth]

if you can modify the importer i think you can just set the name property on the subassets as it adds them

[tough ibex]

I keep reaching deadends like this

thanks guys, I'll try do what you've suggested in a bit and let you know how it goes

[tough ibex]

I'm guessing this is what you mean? I think it will just always use the file name for the main object:

because the sub-assets that aren't the main object have names:

and these do have the right names in the object selector

do importers need to set a main object..?

[stuck plinth]

hmm are the characters imported as subassets or main assets? i assumed they were subassets if they come from one source file

[tough ibex]

subassets, they come from lots of different files in the same folder

[stuck plinth]

in that case there should be other calls to AddObjectToAsset where you add each character i think? you should be able to set their names separately

[tough ibex]

oh sorry I misread

no the characters are imported as main assets, the portraits are imported as subassets

oh hey I got it

I just got it working by not setting a main object with the importer, which lets me just set the object name like you suggested

thanks everyone for the ideas 🙂

also, if there are no other sub-assets, I guess that Unity automatically designates it as the main object, so it can't have a name. as a hacky workaround, I just set a null object as the main one.

hope this helps anyone else in the future

[CreateAssetMenu(fileName = "JumpData", menuName = "ScriptableObjects/Action/AbilitiesContainer")]
    public class AbilityContainer : ScriptableObject
    {
        public List<IActionAbilityData> abilities;
    }

    public interface IActionAbilityData {
        string Type { get; }
    }

    [CreateAssetMenu(fileName = "JumpData", menuName = "ScriptableObjects/Action/Abilities/Jump")]
    public class ActionJumpData : ScriptableObject, IActionAbilityData {
        public string Type => "jump";
        public float jumpForce = 5f;
    }

Does Anyone knows how I can make the list editable in Editor? I want to manually drag the abilities like Jump into the Abilities Container. Thanks for any help

[stuck plinth]

unity serialization doesn't really do interfaces unless you want to mess with SerializeReference, the usual workaround would be to make IActionAbilityData an abstract base class instead

[eternal frigate]

Yeah I thought so, do you think making it abstract helps making it a good modular system? I am not familiar with abstract. It can change at runtime, the abilities container

[stuck plinth]

it's basically exactly the same as using an interface, the only restriction is that you couldn't make another implementation that wasn't a ScriptableObject because you're stuck with one base class

[eternal frigate]

Ok thanks I will look into it 🙂

[dusty wigeon]

You either use SubAsset or SerializeReference.

https://docs.unity3d.com/ScriptReference/AssetDatabase.AddObjectToAsset.html

[eternal frigate]

with SerializeReference the list is shown but I cannot add the interface object to the list.

[dusty wigeon]

Yes, it is expected. You need to add them manually or create a PropertyDrawer.

It is an oversight of Unity I would guess. Pretty dumb in my opinion.

FWIW if you use odin inspector (i couldn't live without it lol) you get much better support for serialized ref fields

Why threads who's SV_DispatchThreadID still continue executing code even if I write a if to stop these threads?
This array is only for testing, and the code below shows what these numbers mean.

Triangle a;
a.a = vert[0];
a.b = id;
a.c = float3(sizeX, sizeY, vert[0].w);

I'm trying to implement an algorithm called Marching Cubes

[misty walrus]

Not an answer to your question, but there's this repository if you're interested: https://github.com/SebLague/Marching-Cubes and they also did it in a compute shader: https://github.com/SebLague/Marching-Cubes/blob/master/Assets/Scripts/Compute/MarchingCubes.compute

[loud wadi]

I was watching his tutorial just now XD. He also stopped these threads by adding a if at the beginning of main function, and in my other project I also used compute shader to generate terrain, and worked fine. But this time the if statement didn't work, maybe that's because that project writes data using the id instead of reads data using the id, and I just did't aware of it...

So the if statement CAN stop the thread theoretically, but the array tells me it can't

Ok problem solved...I just typed > instead of || . This silly mistake confused me half an hour... I need to see the eye doctor as soon as possible : )

[vale spindle]

I want to make simple visuals for aoe attacks: shapes like cones, circles, curves etc.. But i need to project them on slopes and stairs. How would i do that?

[compact ingot]

Decals?

[west nexus]

Aight got it

[calm mica]

I'd appreciate it if anyone can give me an idea on how I might solve this problem.
I'm trying to make it so that ceilings are automatically added when I create a room. I was thinking of basically spawning a ceiling prefab at each point within a room but how would I even detect those points?

[sly grove]

how are you creating rooms?

basically it sounds like you need to do some procedural mesh creation

[calm mica]

i place down wall prefabs
the blue gizmo is the start point, red is the end.
the green is where the prefab is spawned

[sly grove]

this is probably not a very efficient way to make a room...

either way you will need to do some procedural mesh generation here

you could also make roof prefabs if you want the player to manually place roofs

it's unclear what the desired gameplay is

how do you detect when a room should get a roof?

or when a room is complete?

[calm mica]

basically each wall has a list of connected walls

then a different script uses depth first search to go through each of these connected walls until it loops back to the start

the gameplay is a building game like the sims

[sly grove]

so when a complete room is detected you want a roof to automatically be created?

[calm mica]

yup

[sly grove]

Ok so you're essentially going to have to solve this problem in order to generate such a mesh:
https://en.wikipedia.org/wiki/Polygon_triangulation

that article should be a pretty good jumping off point to find algorithms

I love how nicely that preview image captures the problem haha

[plucky laurel]

how would you do flood fill of the room area?

[calm mica]

Do you mean this? I suppose I would need to know which squares/nodes/points are inside of the room and from there just use a foreach loop to change the material of them all

[plucky laurel]

how would you know that?

[calm mica]

one way i guess would be to check for nodes around each wall
and then qualify and disqualify them based on direction? perhaps

and once those are done go for each neighbour until one of the wall nodes are found

and on and on until everything has been visited

[plucky laurel]

if you have a way to get the area inside walls, then you can marching square it for the ceiling tiles

or to generate a mesh

[calm mica]

that makes a lot of sense 👀

I am trying to build an android build of my project, but i am having this error:

java.lang.AssertionError: annotationType(): unrecognized Attribute name MODULE (class com.sun.tools.javac.util.UnsharedNameTable$NameImpl)
    at com.sun.tools.javac.util.Assert.error(Assert.java:133)```
and then it lists a bunch more "at com." things. What is this and how do I fix it?

[uneven mauve]

Moving to advanced because this is tough:

I am trying to tick all of the properties on this enum for an object but I can't. It just won't let me tick them individually, or the "Everything" item

[System.Flags]
public enum BuildingNeighbours : byte
{
    None = 0,
    North = 1,
    East = 2,
    South = 4,
    West = 8,
}

[austere jewel]

If you can't change it then either you're using a custom editor that's not correctly dirtying changes, or you're resetting them

[uneven mauve]

I can see it in the inspector for the script

[sly grove]

can you show how you defined the field for this?

[uneven mauve]

public class PrefabManager : MonoBehaviour
{
  public string BuildingName;
  public GameObject BuildingPrefab;
  public GameObject BuildingHolographicPrefab;
  public BuildingNeighbours BuildingNeighbours;
  public int Health = 100;
}

[ember temple]

https://forum.unity.com/threads/byte-enum-inspector-issues.1078073/
Found this, since there’s only 5 options you can change it to sbyte and it should work fine

[sleek terrace]

Well step in the right direciton

[austere jewel]

Oh yeah there are several versions of Unity where byte flags were just busted, I forgot because I'm on a release where it's fixed

was very annoying to make settings pages that just didn't work for no reason

[lilac lantern]

Is it possible you're using code that's not supported on android or something? com.xxx.xxx is the standard naming convention for packages in java.

[brisk spruce]

Anyone know if its possible to support in or readonly ref variables with <Action<T>> when you invoke it

or anything equivalent, I want to bind to an event that is utilizing an in / readonly ref variable but the binding is handled inside a function

IE:

void Bind(Action<int> method) { ... }

But Id like to be able to utilize one with a ref instead

[austere jewel]

You have to define your own delegate

[brisk spruce]

ah yeah perfect, that does it

thanks!

am I correct in understanding that by utilizing in variables readonly as much as possible, that should be more performant?

as that just passes a readonly ref of the var, instead of a copy of the var, to each method call?

@austere jewel I have it like this now, Im hoping that this small change should further improve performance for very low effort, it feels good having it be in variables from top to bottom now
https://gist.github.com/SteffenBlake/ace74a893d0b16c30a7eb2a42d6d9230#file-propertywatcherbase-cs-L177-L192

Part of me is considering if its worth it to also add in support for binding to an old + new delegate, though I havent had personal use for it yet

[austere jewel]

it'd only matter with readonly structs. If you do it with reference types it's doing nothing, and if your struct isn't marked as readonly it does a defensive copy anyway and you incur that cost

[brisk spruce]

most of my structs are marked as readonly yup

is there a readonly version of int, string, etc?

[jolly token]

Primitive numeric types are immutable. String is also immutable and reference type so no point of using in.

[brisk spruce]

I'm supporting generic types so any struct

[heavy salmon]

Just updated C# extension in VS Code, what is this?

[austere jewel]

It literally tells you?

[heavy salmon]

no, it wasn't there before updating so why does it show now

[heavy salmon]

So what does it mean?

[austere jewel]

What are you not understanding?

[heavy salmon]

how can I not be using it when its working in game?

[austere jewel]

Where do you call it?

[heavy salmon]

this even shows in the update method

and the start

[austere jewel]

well, those two methods are called magically by Unity, so you'd need proper Unity support for that to be detected as used. VS Code's extensions are deprecated, so I have no idea what the state of things with it are. I'd recommend using Rider if you can, or VS Community if you're having issues with VS Code.

                    currentGoal.OnStart();
                    break;

this is the waiter

[stuck plinth]

the coroutine should stop when you exit so disposing it in OnDestroy or something like that is probably the way to go, what errors did that give you? i guess maybe the job still tries to access it on the last frame?

[glacial wedge]

Ok, I solved, the problem i was facing inside OnDestroy were 2 differents:

1. when the job was in progress. I couldn't dispose the array used by the job
2. when the job was finished. I couldn't dispose the array because was already disposed.

fix:

        protected virtual void OnDestroy()
        {
            if (!_jobHandle.IsCompleted)
            {
                _jobHandle.Complete();
                _goalFacts.Dispose();
                _actions.Dispose();
                _facts.Dispose();
                _plan.Dispose();
            }
        }

[scenic forge]

Complete blocks the thread though, might want to rethink the approach if the job takes long.

I just discovered Unity Recorder and have a question.
So I have my primary camera using for gameplay on Display 1.
Then I added a camera that "films" the player character moving around - I set this camera to Display 2 so I can still play the game on Display 1.
However it seems even to I set the filmcamera in the Recorder settings the visuals are not recorded because the filming camera was not set to Display 1.

What is the correct way to achieve recording from a different camera then my Player camera?

[polar oxide]

Hello everyone, quick question:
Has anyone here experience with developing for the steamdeck? I'm having issues with the case that the steamdeck goes into sleep mode while the game is running. As it wakes up, it may require a PIN to activate again, and I would like to suspend the game and the input system until that lockscreen disappears. Unity's onApplicationFocus does not fire. And I'm struggling to find related events, etc. in the steam documentation.

What is everyone else using to avoid that problematic state?

[flint sage]

Do you have pause in background enabled?

[polar oxide]

In the project settings, we have "Run In Background" enabled, because we handle the suspended state manually for different platforms.

[green crane]

This unity button works just fine when in screen space positioning, but when turned into world space positioning, the game does not register the button press, or even react to a mouse over.

It is placed the highest on the hierarchy (ui, highest tier), and has a level 10 on hierarchy.

Thank you 🙏

[empty shell]

Hello,

I have a problem where I try to pause the game when the Steam overlay is enabled. Right now the game pauses and unpauses between each frames.

    private void Update()
    {
        if (SteamManager.Initialized && SteamUtils.IsOverlayEnabled())
        {
            pauseMenu.ButtonPausePressed();
        }
    }

This is in a SteamAdapter class.

Can anyone help me find a way to pause/unpause the game when the Steam Overlay is enabled?

[long ivy]

your code is doing what you told it to do. Don't press the pause button if the game is already paused

if you're pausing based on TimeScale, Update will still be called at the normal rate

[empty shell]

The thing is that I never opened the overlay, but it still pauses 🤔

[flint sage]

You'll probably start getting focus events if you disable it

[fresh salmon]

the error is pretty much the same as the first one i sent, but this has more on the top and bottom. i dont know why they have two different errors for this

[lilac lantern]

First suggestion is to update unity. What unity version are you using?
Second, do you have any lambda-style code? Reduce that if updating doesn’t work.

Before updating i suggest you use some sort of version control software so you can revert if anything goes wrong.

[sleek terrace]

I need a better/faster way to run this loop.
Im generating a 500 x 500 grid mesh, I need 500+fps

help a brother ouyt

[lilac lantern]

Try .AsSpan()?

And iterate over a span collection

Also don’t convert idata to an array in the loop

[sleek terrace]

never heard of this, what is it soldier

[lilac lantern]

convert allData an array of arrays, then a span generated from allData.AsSpan().

[lilac lantern]

It’s in namespace System, I don’t fully understand it, but it’s the fastest loop in C# according to user benchmarks from stackoverflow.

So have a new variable and on start convert the list allData to an array of arrays. Then use .AsSpan to get it as a span in the update method, then iterate over that with a regular for loop and indexing.

[sleek terrace]

as so?

[lilac lantern]

no, ill provide an example.

something like:

void Update() 
{
  if(useGPU && ready) {
    Span<InstanceData[]> spanData = newData.AsSpan(); // new data being allData but converted to an array in start / awake.
    for(int i = 0; i < spanData.Length; i++)
    {
      Graphics.RenderMeshInstanced(rp, hex.HexMesh, 0, spanData[i]);
    }
  }
}

I'll leave this here for you @sleek terrace as I have to go:
https://learn.microsoft.com/en-us/dotnet/api/system.span-1?view=net-7.0

I'm sure you can figure it all out, but you can test that and see if it's faster, I believe it will be, although I don't know if it will achieve your 500 fps.

[sleek terrace]

Thank you very much!

[lilac lantern]

also, span is a ref struct so you can't have it as an instance field, you have to construct it in the method.

[sleek terrace]

just noticed lol

15 - 20+ fps

[sleek terrace]

its called in update?

[plain temple]

yeah those are just checking for input

[sleek terrace]

it looks like ur code worked as expected tho

u bought the weapon and it dropped

[plain temple]

im trying to make if for instance i have a beretta in my inventory and then im buying a beretta it will drop the purchased one

but to equip weapons it has to be in the inventory array

and it says missing in the inv array

[plain temple]

right now i only have 2 weapons but if i add another weapon that is a pistol(secondary weapon) it will drop that aswell

[sleek terrace]

so im guessing you can hold 3 weapons...

since your looping through all your guns before checking if u have additional space

you end up dropping the weapon

Im guessing

[plain temple]

yeah i can hold 3 slots and the 3rd one is used for knife which cant be dropped

[sleek terrace]

are you checking if ur inventory has space for an additional weapon before dropping?

[plain temple]

no because the space is limited to 2 weapons

well 3 gameobjects but the 3rd one is used for a knife so we can exclude that

[lilac lantern]

you should benchmark it in a build btw, editor can be slower.

also, if you don't care about actual time and just want more fps, you can limit it to a certain number of loops per frame.

[winter folio]

I really need help Ive been sitting here for a few hours and I cant get my head around this

https://hatebin.com/rnuttrauot
So my first script here is linked to another script for a door (yes Ive done a door script like this because I wanted a small cutscene animation to play while opening it because I also need to additively load a scene)

https://hatebin.com/qqbyqsnauv
On THIS loadout script I need my weapons to be holstered automatically. It works perfectly fine with my keys 1,2,3. 3 is just an empty object for hands or whatever, 1 is a pistol and 2 is for a rifle. But for some reason if I call it from that first door script (need them to holster) then it is stuck in a loop of holstering and equipping constantly. The m4IsEquipped does turn false and the pistolIsEquipped does aswell and the selected weapon int also changes, but the weapon I just had out is stuck in that loop

[winter folio]

it DOES THE SAME THING and its driving me crazy because I dont understand why or how its doing that

tried everything I can think of

[long ivy]

step through it with a debugger or add a lot more logging

[winter folio]

debugger?

fuck it im just gonna redo everything i cannot be asked for this shit

[sacred zephyr]

https://puppetcombo.tumblr.com/image/173900547345

ok so..this is sort of complicated

but i like to think its easier doable

how would you go about creating a circular inventory?

ive been basing all my info off this one reddit comment as there is literally nothing on the internet as far as tutorials for silent hill-esque inventory systems

[austere jewel]

Google "unity carousel"

[sacred zephyr]

its that easy?

[sacred zephyr]

apparently not

[brisk spruce]

I mean, that really covers pretty much all of it

[sacred zephyr]

I know it does

the thing is that im too stupid to understand this part

everything else is something I understand

[austere jewel]

Then why are you asking in #archived-code-advanced

[sacred zephyr]

.

[brisk spruce]

Whats the formula for the circumference of a circle?

[sacred zephyr]

3.14?

[brisk spruce]

thats uh, thats just a number mate

[sacred zephyr]

im a little slow

[brisk spruce]

I mean thats pi which is indeed part of the formula

I mean its straightforward though, how many degrees are in a full circle?

[sacred zephyr]

multiple the radius by 2 to get the diameter, multiple by pi, thats circumference

i see

[brisk spruce]

Like if you have 6 items in the circle equally spaced out, how many degrees are between each one?

[austere jewel]

You can take this to #💻┃code-beginner or #archived-code-general where it'd be more suited, or just look at the numerous results for carousel UIs/inventory in google which you can pull together to get all the info you could ever need.

[sacred zephyr]

uhh 60

[sacred zephyr]

also i do a lot of research before coming here, i dont mean to bother anyone whos really good at this stuff as i find getting help embarassing - i do really like to learn on my own

however i thought this code was advanced

[inland knoll]

Hey, so if I want to have glass shattering in my game realistically then how would I do that? I watched some videos and googled on the topic so I roughly know what to do, but not how to do it. I think my best bet would be to create a fracture pattern (as seen on the picture) and then split the glass from those lines into new gameobjects, but I am unsure about how to do that.

[sly grove]

this is always an option:
https://assetstore.unity.com/packages/tools/game-toolkits/rayfire-for-unity-148690

[inland knoll]

I unfortunately am completely broke for I am still a child

so no

it is not an option

I am looking for what is being explained in this video: https://www.youtube.com/watch?v=nuHg6_IIyK8

[dusty wigeon]

You can manually break a mesh in multiple part in Blender. This is the cheapest way of doing that.

[inland knoll]

I'd rather not have to do that with everything I create, plus it wouldn't work if a bullet is shot into different places on the glass

well, okay it would work, but it would look awful

[dusty wigeon]

Then your only option is to break the mesh following a fracture pattern.

[inland knoll]

indeed, but my question is how to do that

[dusty wigeon]

With computer shader ?

You can also do it on the CPU

[inland knoll]

surely I don't have to learn a new coding language and write a shader right

[dusty wigeon]

With the Mesh API

[dusty wigeon]

Yes, otherwise performance are going to be atroce.

[inland knoll]

which is yes for?

write shader or no write shader

[dusty wigeon]

You gonna need to use a computer shader

[dusty wigeon]

Here something I have done in 6-8 hours trying to learn that.
https://pastecode.io/s/ep5x8s6z

It splits a mesh in two

[mellow sail]

do you guys know how to fix jitter on wheeljoint2d when on high speed?

[inland knoll]

thats a computer shader?

[inland knoll]

Also in this video I, from 0:30 to 0:40 seems to make it at least look very simple, and also if your code only splits it into 2 then how would I be able to accomplish anything like that

[inland knoll]

^

also 1:00 to 1:15 seems to explain how it was done, but I dont exactly get how to reproduce it

[dusty wigeon]

No idea. However, it is expensive to do those calculation and if you want appropriate performance you might want to use a Computer Shader. I'm not saying it is impossible, I'm just saying that should be your aim.

[inland knoll]

I mean, I dont think they used a computer shader, but it seems to run really smoothly

[dusty wigeon]

And extrude them back to 3D models.

This is how he did it.

[dusty wigeon]

Either way, it is always better to have a version that runs on the CPU for development. In other words, you should start with a CPU version.

[inland knoll]

I believe that I can do this with help, so I'm gonna try to break this down to smaller steps and ask this server for help if I can't figure out how to do the step then.

[inland knoll]

Hello, I am back here, with some help I figured out the next step I need to do, which is: Deleting my shatter map's every vertex outside of the glass and giving the shatter map a new border with the shape of the glass's border

(Sorry I couldn't think of a better way to explain it)

I'll try to make a picture so it would be easier to understand

[tardy bobcat]

i normally would never go in here for help but tbh no one ive talked to can help, ive got a bullet pooling script and a bullet script, the bullet script is supposed to invoke destroy after a despawn time or if it collides with an object it is supposed to call the function and cancel the invoke, very simple however, the collsion arent detecting i have a kinematic rigidbody on my bullets with continous and interpolate on with always awake for collison detection and i have static rigidbodies and on trigger colliders on all my walls and ground so they should detect and its a basic on collison enter fucntion but it just is not running all the alyers can interact in the collsion amtrix and i have even changed them to the same layer and there was no lukc and i just do not know how to solve it

[inland knoll]

I am not a helper, since I am fairly new to Unity, but maybe it is because the bullet hasn't got the collider on convex? Also, fast small colliders might clip through walls to some extent, mostly when the wall is a plane
