[ashen jasper]

i havent programed in unity for a while

but i look into that

[mild coyote]

Note that I'm not sure if it will work when run in game, I just tested it in editor mode XD

[ashen jasper]

that actually works but there a problem that comes to this

the mouth left and right have different propertys

the plan is to basically let the game know if he is facing left to change the angles of all the armitures to mirror animation

Actually now that I think about it. This could save me on resources

[ashen jasper]

So umm i was wrong there are many issues when it comes to this

[woven veldt]

Hi, I have a model which has a bone structure with objects added to the end, which are rotating in an endless loop. This is pared with the rest of the mesh which is not animated. I want to try and convert this object to a single entity. Is this possible or would it come out as 2 entities. One which holds the animation and one which holds the other static mesh?

[lean sail]

This isnt a code question. To somewhat respond, this all cant just be 1 object if parts of it are moving. It wouldnt really make sense

[flint swallow]

i'm trying to distribute a points on a scale of 1 to 10 evenly using this code, but it's just spitting out 0s:

 private float[] scale;

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


    scale = new float[5];

    for (int i = 0; i < 5; i++)
    {
        scale[i] = i / (5 + 1);
        Debug.Log(scale[i]);
    }
}

[somber nacelle]

you are doing integer math

[flint swallow]

i dont understand

[somber nacelle]

do you know the difference between integers and floating point numbers?

[fervent furnace]

not code general
int 1/int 2 =0

[flint swallow]

ya i do

wait

il cast it to float and will that fix it?

[somber nacelle]

just slap an f on one of those magic numbers

[flint swallow]

ok

[flint swallow]

why?

[somber nacelle]

#archived-code-general message

[flint swallow]

why is 1/2 = 0 in int

[somber nacelle]

#archived-code-general message

[knotty sun]

because ints cannot have decimal places

[flint swallow]

🤦‍♂️ im dum

[somber nacelle]

so then the answer to this question #archived-code-general message
was very likely "no, i do not know the difference between integers and floating point numbers"

[flint swallow]

no i just had a brain malfunction

so how can i fix for this code:

im trying to distribute points evenly on a circle

[knotty sun]

cast i to float

[somber nacelle]

what is currently wrong with it

[flint swallow]

its still giving 0

[somber nacelle]

and you've actually saved/compiled the code after making that 1 a float?

[flint swallow]

k casting i to float fixed it

ya

im not that dum

[somber nacelle]

well casting i to float wouldn't be necessary if the denominator is already a float because int divided by float returns a float

[flint swallow]

no but it only worked after casting i to float, idk

[somber nacelle]

prove it by removing the cast

[flint swallow]

does that function correctly map the values evenly from 0 to 1?

[flint swallow]

k wait

[fervent furnace]

range of i is [0,count-1] where dominator is count+1

[flint swallow]

this isnt correctly mapped tho

this is my coords function:

[somber nacelle]

looks like you need one more position

[flint swallow]

ok, i just didnt save it before playing, it works perfectly

[somber nacelle]

lol

[hexed pecan]

Classic

[flint swallow]

the mapping code supposed to give 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9. but its giving:

[somber nacelle]

anyway, this is what i had done for something similar. I was shooting raycasts in a cone/circle rather than putting points on a circle, but the concept is really the same

var maxAngle = _fovAngle / 2f;
var offset = _rayCount > 1 ? _fovAngle / (_rayCount - 1) : maxAngle;
for(var i = 0; i < _rayCount; i++)
{
    var angle = -maxAngle + (offset * i);
    var dir = Quaternion.AngleAxis(angle,Vector3.up) * transform.forward;
    Debug.DrawRay(transform.position, dir * _rayLength, Color.green);
}

[flint swallow]

y isnt mine woring

[hexed pecan]

Btw the Mathf.Clamp line does absolutely nothing

[flint swallow]

ya i figured that out

the trig functions are periodic

[visual tendon]

Guys, are fancy filters supported by AssetDatabase.FindAssets? I'm trying the code below but always gets 0 results even when the file do exists:
string[] guids = AssetDatabase.FindAssets("p: dir:\"UI/Controls\" MyFancyUIDocument.uxml");

It does work in Unity's search utility 😖

[somber nacelle]

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

[hybrid relic]

cuz u arent rounding anything

ur using the values you get without like "smoothing" them

[flint swallow]

no i figured out, since i is not actually from 1 to 10 but from 0 to 9, u just dont add 1 to the denom

[hybrid relic]

also seeing the rest of your messages, you might want to take a basic C# course

[wicked elbow]

hello
i kinda need help

[flint swallow]

this works

[hybrid relic]

cool, why dont you start by asking your question

[knotty sun]

dont cross post

[visual tendon]

Looks like we can't.. the thing is using t:UXML also doesn't work

[wicked elbow]

so i follow a tutoral and he put rigid body on sb but i cant see the rb place on mine i have exactly the same code

[hybrid relic]

want to get yeeted by a mod ?

stop cross posting

[somber nacelle]

stop crossposting. you've been answered in #💻┃code-beginner

[wicked elbow]

wth is cross posting

[somber nacelle]

posting your question across multiple channels

[hybrid relic]

you very clearly are a beginner and ask beginner question, there is a seperate channel for that, please ask in #💻┃code-beginner if you have such beginner questions the next time

[flint swallow]

ya il post there from now

[hybrid relic]

Also please look at a C# Tutorial so you understand the coding language

[flint swallow]

i just saw general and popped in here

[flint swallow]

no i understand c#, i actually made a monogame game once, its just i forgot integer math

(i dont know how making a monogame game proves my c# intellect but... just trust me)

[hybrid relic]

you dont just forget interger math

[flint swallow]

i dont like int

[hybrid relic]

unless you dont code much or like had a big pause

[flint swallow]

ya i had my final exams

so i had a loong pausr

[hybrid relic]

anyways before asking such basic stuff again, look at these to refresh your knowledge, should help you get back in:

https://www.youtube.com/watch?v=XtQMytORBmM

[flint swallow]

btw if i needed someone to playtest my game, is there a channel here for that or am i gonna have to make friends

[hybrid relic]

Friends

or put it on itch, with the warning that its a playtest / alpha

[flint swallow]

but what if i finished only the movemnt and wanted someone to tell me if it feels well

its like 1 minute of playtesting or smth

like, the art is just borrowed from random files i have from modding games (this one is from celeste)

[lime gazelle]

what happens if a server passes in a wrong argument in a client RPC which will lead to a error on a client (listOutOfIndex) will the client crash or will it be ignored if so will the list return null?

[somber nacelle]

it will throw an exception on the client just like doing that in any other context would

whether there are ramifications depends on the actual context of the exception just like literally any exception
also #archived-networking for networking related questions

[lime gazelle]

k, thanks.

[visual tendon]

I'll use labels then.. 🙄

[hybrid relic]

that depends strongly on your network library

and yes #archived-networking might be better

[hexed pecan]

You are mixing backslashes \ and forward slashes /. Is that intentional?

The backslashes seem out of place in the code, especially the first one

[somber nacelle]

they are escaping the "

[hexed pecan]

Aah, makes sense then

I really gotta learn regex and such

[nova leaf]

so, i am using asset bundles for mods and it works perfectly, however, if i spawn a prefab, audio clips are not found, even tho they are in the asset bundle too

[quaint rock]

How is audio referenced

[nova leaf]

it is just inside of an audiosource within the prefab, but the clips are also iuncluded in the asset bundle, do i have to load them manually?

[quaint rock]

Should not have to, as long as the audio clips are referenced they should auto be included in the bundle and get loaded with it

[nova leaf]

hmm ok...

[quaint rock]

If you don't manually include the audio clips, I would check and see if they get auto included because the prefabs reference them

[quaint rock]

Other dependencies are being pulled in fine?

Like textures, materials etc

[nova leaf]

i just tested it, looks like it does, yes

[quaint rock]

Strange, and in the asset bundle browser you can see the audio

[nova leaf]

browser?

u mean in unity in the folder?

[quaint rock]

https://docs.unity3d.com/Manual/AssetBundles-Browser.html
It's a tool for just lets you look in built bundles

[nova leaf]

ah

found the issue

strange one

[quaint rock]

Oh what was it very curious?

[nova leaf]

the object the audio source is on has to be active, in the prefab it was not active because i set them active in a function

very strange

why is it like this tho

the modles which are not active work

[quaint rock]

Hmm never run into that before, but it seems very counterproductive

Will test when I get to work later

What unity version?

[quaint rock]

Work around I guess is keep then active in prefab and disable on Awake

[nova leaf]

yeah

will do that

[quaint rock]

Hmm will look at that later, I am using 2022.3 for a project at work too. Though using addressables not bare asset bundles

[somber nacelle]

not a code question #🤖┃ai-navigation

[neon plank]

Ups

[static matrix]

What would be a solid solution for detecting when something can jump to follow something?
I was thinking something like shoot a raycast in the direction of the prey, if it hits something, shoot another raycast from that X but the Y of the prey, and if that hits then presume you can jump to the ting

[static matrix]

ontriggerenter calls both ways right?
like it calls on a trigger when it enters a collider or no
no
im wrong

[flint swallow]

how can i create a mask inside which i can draw a texture using a list of points

[somber nacelle]

OnTriggerEnter is called on both objects involved in the trigger overlap. This can be two trigger colliders or one trigger collider and another non-trigger collider

[static matrix]

so if a trigger enters a non-trigger is ontrigger enter called on the trigger?

[flint swallow]

i have this line renderer that displays the edges (the blue thing) i want to fill it with a texture

k il wait

[somber nacelle]

OnTriggerEnter will be called on both, yes. provided there is a rigidbody on one of the objects
https://unity.huh.how/physics-messages/trigger-matrix-3d

[static matrix]

oooh thats
interesting
you should use a polygoncollider

[static matrix]

unsure how to fill it with a texture, but you could use an occlusion mask(?) to just render that texture everywhere but have it be hidden outside the area

[flint swallow]

ya thats what i was thinking

[static matrix]

although i've only done that the other way around, having it be vis everywhere except the target area (for flashlights)

[flint swallow]

so basically (if u read my prev msgs) i make those points move in a circle. its likea slime character but using rigidbody physics so i will use these points to render the skin of the player but make them have wall collision and stuff, so itl feel more softbodylike

but i didnt think abt how i can make the texture inside respond to movement

i havent got this figured out yet

if the player moves the points rotate clockwise or anti clockwise (right and left respectively), i want to make a fill that's mostly procedurally generated

so a texture wont work probably

mabey a gradient fill between each points

will i be able to generate a mesh to fill the inside of the polygon and use an uv

so i could to warping and stuff

[hexed pecan]

You can generate a mesh, yes

You can even generate a skinned mesh (mesh with bones), it could fit the usecase for softbodies

Skinned mesh would be good since you wouldn't have to regenerate the mesh every frame, just move the bones to warp it

[flint swallow]

idk how

[hexed pecan]

It's a bit more advanced though since you have to generate bone weights/bind poses

[flint swallow]

where can i learn

[hexed pecan]

You can get started with mesh generation here:
https://catlikecoding.com/unity/tutorials/procedural-meshes/

It doesn't cover skinned meshes/bones though. That's more advanced stuff.

If you don't like reading then I don't have any video tutorials to suggest but they probably exist

[flint swallow]

so smth like this and i can apply an uv to it?

[hybrid relic]

just an idea wouldnt it be just easier to have a circle with a slimey shader ?

[flint swallow]

ooh

[hexed pecan]

Sure if that's what they want

[flint swallow]

whats a slimey shader

[hexed pecan]

I didn't read the whole convo tbh

[hybrid relic]

a shader that makes the object look like slime

[flint swallow]

does it give like textureing and stuff

[hybrid relic]

a shader is something that changes the visuals

yes

[flint swallow]

i also want it to jiggle

[hybrid relic]

yep can all be done in shaders

sounds way less complex then your way of archiving it imo

[flint swallow]

but not affect other objects due to jiggling

[hybrid relic]

a shader doesnt affect anything

its just visual

[flint swallow]

where to learn shaders

feel like i should be in code-beginner rn

[somber nacelle]

check the docs pinned in #archived-shaders

[hybrid relic]

how are you always sniping my answers

[scarlet viper]

what if i first hit an object, then hit another? Will **OncollisionEnter **get called twice and **OnCollisionExit **not at all (if i still touch them) ?
Or is the method OncollisionEnter going to be called once, but will contain contacts for both objects that i collided with?

[somber nacelle]

OnCollisionEnter would be called twice there, yes. And OnCollisionExit will only be called if any of the pairs of objects colliding stop touching

[hard viper]

Every Physics update, Unity generates a bunch of collisions. Then, for every Collision, it checks both things in that collision for OnCollisionEnter/Stay/Exit, and invokes the relevant one if it finds it.

If one gameobject is involved in multiple collisions, then it will potentially get multiple calls on that frame.

Beware that collision calls are not invoked in any particular order

If mario collides with a super mushroom and a goomba in the same frame, and you detect by OnCollisionEnter, then you better make sure the same thing happens whether the mushroom or goomba collision gets called first.

[static matrix]

I was like "damn, its only 930? it feels like its been much longer"
then I realized its because I was not used to being this productive 💀

[plain spire]

how can you create a custom character collider?

I'd like to try and make my own custom controller, without using unity's physics or anything

and I'd like to make it cylinder shaped, and not a capsule, but how would you detect collision?

[leaden ice]

without using Unity physics at all? Then you're basically talking about building your own physics engine from scratch. Not a small feat

[plain spire]

well, I'm not totally insane

[leaden ice]

You're better off using a kinematic Rigidbody and a Cylinder-shaped mesh collider

[plain spire]

raycast based, rather than collider based

[leaden ice]

You can use this https://docs.unity3d.com/ScriptReference/Rigidbody.SweepTest.html

[plain spire]

I've actually tried cylinder shaped mesh colliders before, and it's not super smooth which is why I'd like to try this

[leaden ice]

Custom collider shapes aren't possible

[plain spire]

it's not that important to me I just always wanted to try this out

[leaden ice]

aside from MeshColliders

[plain spire]

oh yeah I know, I just thought like

surely there's a method of raycasting that can allow custom shapes? idk

[leaden ice]

For casting shapes you either do Rigidbody SweepTest with a MeshCollider (custom shape)
Or use the existing methods here:
https://docs.unity3d.com/ScriptReference/Physics.html

There is no custom shape casting other than SweepTest

[plain spire]

hmm alright

I'm mainly asking because I saw a tweet by a guy making a skating game

and his entire thing is ps1 styled so his character doesn't use rigidbody physics

the map is still made of colliders obviously but it doesn't like, use physics like that it's all raycast based

[leaden ice]

He is using some combination of these things #archived-code-general message

[hazy basin]

does anyone have template for a runner game like subaws surfer ?

[plain spire]

ah neat!

[plain spire]

i mean this would require using a rigidbody right?

[leaden ice]

sweeptest would

but I don't see the issue with having a Rigidbody

just make it kinematic

[plain spire]

oh yeah but there's checkcapsule too fair

[plain spire]

oh there isn't this is more for like

[leaden ice]

You can also just use this https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131

[plain spire]

idk fun? try make a character controller without the colliders and stuff

[plain spire]

oo

I am gonna download this and rip it apart and find how it works

[hybrid relic]

that sounds extremly unperfomant

[spring creek]

Raycasts are extremely cheap
Maybe I'm missing something else?

[hybrid relic]

Arent they quite heavy in big amounts ? Especially in the amount you would need with a character controller

[spring creek]

No. A single raycast is almost free honestly. Scaling up is cheap

You can use a LOT of them no problem
It's a common misconception that they are expensive though

[lunar python]

I am currently using Kinematics Rigidbody for all of my GameObjects and currently trying to set up my own physics sytem. I have recently read an article about Integration Basics which covers Semi-Implicit Euler, Explicit Euler, and RK4. Here's the implementation code: https://paste.ofcode.org/Mc7kMmw9gNLunsDNZDiMxS. I wonder which system would suit best a 2D top-down game. The article also mentions symplectic integrators but I still wonder which one is great. Can someone give me some recommendations?

[junior pond]

Hello! I'm working on this turret, and for the first few seconds the bullets move as expected. But then after a couple of seconds the bullets fly to the left side of the turret. How can I fix this?

This is what I've got for both the turret and the bullet.

Bullet: https://gdl.space/abesosubob.cs

[knotty sun]

I would suggest, looking at your code, that the problem lies with Lean Pool

Although maybe you dont want firePointL.rotation or firePointR.rotation but firePointLforward and firePointR.forward

[junior pond]

In LeanPool.Spawn?

[knotty sun]

I have no idea what LeanPool is but LeanPool.Despawn(this) looks odd to me

[lunar python]

Seems like an Object Pooling script

[knotty sun]

for all I know it could be a subscription to the local swimming pool, lack of information

[lunar python]

https://assetstore.unity.com/packages/tools/utilities/lean-pool-35666
seems like it's from the asset store

[knotty sun]

Well if it is object pooling why Spawn a gameobject and Despawn a script ?

[lunar python]

Did the issue get fixed? I wanna ask if you did actually spin the turret while firing the bullets

[junior pond]

I got it fixed in another server

It turns out that for the bullets I needed to use OnEnable instead of Start because of LeanPool

But thanks for helping out!

[knotty sun]

So I wasn't far off, not bad for a guess

[ancient magnet]

I just made an override of a super complicated script with a bunch of variables that I'd have to reassign, but unity won't let me copy and paste the values into the override, is there any way to fix this?

[knotty sun]

custom editor

[ancient magnet]

can you elaborate?

[knotty sun]

sure, data is type specific i.e. is linked to the type of the class. in order to overcome this you need to write a custom editor to expose the underlying class to the editor rather than the inheriting class

[ancient magnet]

Alright, I'll try

[static matrix]

if i have Update in a class as well as in it's child class (both private) do they both run?

[heady iris]

No. The Update method from the actual runtime type will be executed.

[static matrix]

so the lowest public one I presume?

[heady iris]

If you want to run both, make the parent method virtual, override it in the child, and call base.Update(); in the child

[heady iris]

If you have an instance of B, you'll get B's Update method

[heady iris]

This is what the Selectable class does

[static matrix]

cool

[heady iris]

its Unity messages are protected and virtual

so child classes can override them

[noble moth]

Hello everybody! I am having issues building (for windows). The build is taking longer and longer each time, but more importantly: the first time the game loads, it seems multiple effects are disabled (post processing, volumetric fog, some materials). after reloading the scene in the game, it looks OK. I tried loading other scenes before and then my main scene, but it still looks wrong the first time. Does anyone has an idea about what could it be? (everything works fine in the editor)

[hexed pecan]

It can be private

[static matrix]

cool

public void ShuffleClats(){
        foreach (var item in SpawnedClats)
        {
            if(item.GetComponent<Loot>()){
                item.GetComponent<Loot>().enabled = false;
            }
            var BasePos = item.transform.position;
            var RandOther = SpawnedClats[Random.Range(0, SpawnedClats.Count)];
            transform.position = RandOther.transform.position;
            RandOther.transform.position = BasePos;
        }
    }

I had hoped this code would shuffle around a bunch of objects, but that does not seem to be the case, I get a result like this (note the stacking)
any idea why?

(ignore the loot disabler that is not important to the rest of the function)

noooo wait something isn't working right
its not disabling the loot script and I can't collide with them anymore

[hexed pecan]

(Or protected if you need to override it/access it from child class)

[leaden ice]

Shouldn't transform.position = RandOther.transform.position; be item.transform.position = RandOther.transform.position; ?

[static matrix]

im so dumb

[leaden ice]

Also better way to write that Loot thing:

            if(item.TryGetComponent(out Loot loot)){
                loot.enabled = false;
            }```

instead of GetComponent twice

[hexed pecan]

Small tip, you can replace the double GetComponent with ```cs
if(item.TryGetComponent(out Loot loot))

goddamnit praetor

[static matrix]

[hexed pecan]

Or even have the list as List<Loot> if possible

If it doesn't always have a Loot component then no

[static matrix]

does not always have a loot component

also I use SpawnedClats in a lot of other places so changing the type would mess up things

[hexed pecan]

What's a clat?

I know it's jamaican for cloth

[static matrix]

uh
ok so
you know school gyms

they have those little like
smol cones?
im calling those clats bcause y not

these things

[hexed pecan]

Ah those

[static matrix]

(except these ones animate and swarm you but potato potahto)

I wanted to shuffle them so the one that detects you/is shootable is not the same for each iteration

[heady iris]

oh, those doohickeys

[static matrix]

these frikin guys are as buggy to all hell
sometimes they do damage you, sometimes they dont. Sometimes they grab you correctly, sometimes they dont. Sometimes the hand moves right, other times it gets stuck
its infuriating
i'll fix em later tho

[dark atlas]

I have a question. In Unity, how do I swap a Skinned Mesh Renderer with another mesh thats in an already loaded asset bundle? I was told to use this __instance.gameObject.GetComponent<SkinnedMeshRenderer>().sharedMesh However I don't know exactly how to specify the mesh from the asset bundle when using this.

I have confirmed that the asset bundle I am using already is loading properly.

[static matrix]

ugh the collider just sometimes does not work

idk why

[hexed pecan]

What collider, how are you moving it and how are you using it (OnCollisionEnter/TriggerEnter?)

[leaden ice]

https://docs.unity3d.com/ScriptReference/AssetBundle.LoadAsset.html

[static matrix]

Im fine if it passes thru things just preferably it would detect when it ran into something with OnTriggerStay or OnCollisionStay (2D)
moving it with changing transform
ill finnik with a couple things first hmm

[heady iris]

add a kinematic rigidbody and move that.

https://unity.huh.how/physics-messages/trigger-matrix-2d

[spring flame]

can I depend on an asset inside Resources/ directory, so that when it updates, the dependent scripts also update?

[heady iris]

I don't know what that means.

"The dependent scripts also update"

Are you trying to make a "manager" object that runs methods on a bunch of other objects?

[spring flame]

I am in a process of writing a package, and it depends on some shader partials (.hlsl files) that are later #included in a shader, but this shader is generated by a custom asset. I want it to behave in such a way, that when the included .hlsl file changes, it takes effect in unity, so possibly notify the shader-generating asset that the include changed, so the final shader has to recompile

[heady iris]

ah, okay, you're talking about shader compilation

[knotty sun]

do you know what a reference is?

[spring flame]

I am trying to write a custom asset (or something) that generates a shader source. This is an editor utility btw

[spring flame]

you mean asset GUID?

[heady iris]

I thought Tooster was talking about something happening at runtime with component instances. That is not the case.

[knotty sun]

no, just in general, because it sounds like you think when you reference something it makes an actual copy

[heady iris]

I'm not familiar with how Unity deals with changes in #include'd shader files

[spring flame]

yeah, I know what references are. I think I struggle with the editor asset pipeline and how unity determines how to "update" (recompile/reimport/do something) to assets that reference other assets.

[knotty sun]

I can tell you exactly how Unity handles things like that, very badly in the editor but well at build time

[spring flame]

I've taken a look at how ShaderGraph tries to manage dependencies (for example for "default includes" in generated shaders), but shadergraph is such a big pile of code that it's pretty hard to understand how it works exactly, and i only want something simple for now https://github.com/Unity-Technologies/Graphics/blob/d13e988448aa2ec3b05cb525f7f9b9a587cc5a80/Packages/com.unity.shadergraph/Editor/Importers/ShaderGraphImporter.cs#L67

[knotty sun]

if in doubt write your own AssetPostProessor to handle dependencies

[spring flame]

idk If i'm not in the XY problem territory, because for now I have a "common shader include file.hlsl" inside a "Package/Editor/Resources", and I just didn't see any change when I updated the .hlsl file that the final shader recompiled or updated (and the method for generating final shader returns a fixed string right now that simply imports this include)

[spring flame]

Yeah, probably will have to do that, just that the whole "custom assets" thing seem very convoluted and hard to understand.

[knotty sun]

AssetPostProcessor is actually pretty simple

[static matrix]

hmmmm
I wonder what is causing this

wait does that store all the debug.logs or warns?

[knotty sun]

yes, of course, it's a log

[static matrix]

I didn't know that it was saving those anywhere

Hey all, just some quick math things, if I'm trying to calculate the length of an Image via the length of a song, and it's BPM, how would I do that? I know it has something to do with speed = distance / time but I suck with game engine math and honestly couldn't think of any better math to use here

Here's the same timeline from a few days ago, I just need this to explain the other metric I have

[leaden ice]

wdym by "the length of an image"?

[eager steppe]

I mean like, how long an Image is supposed to be to accomodate the length of a song

[eager steppe]

Like, I have a line running through the entirety of the timeline, which just shows the current position of the song, like how Unity Animation Panel works?

I'm not sure how to incorporate in into a formula to use though

[leaden ice]

How are they related?
Wouldn't the image size itself always be the same?

It's more a question of positioning objects (notes) along the line

[eager steppe]

oh, sorry
the image in this case is the lines. They need to be longer to accomodate the entire song

[leaden ice]

yeah isn't that always going to be the same length?

[eager steppe]

unless I'm going about this the wrong way

[leaden ice]

It depends how you want to do it

like is this going to be scrollable?

[eager steppe]

Yeah, essentially

[leaden ice]

there are many ways to do this

[eager steppe]

It's scrollable and has objects that are dotted along the timeline, depends where the user wants to place events dwon.

[leaden ice]

I don't think BPM has anything to do with this particular calculation. It's basically just totalSongDurationInSeconds * pixelsPerSongSecond

[eager steppe]

hm.. alright

I'll try this, thanks

I'm having a really hard time working with Elevenlabs. It's 50/50 when the files are playable.
I have a good file and a bad file I have saved.

From the bad file I get this error: Error: Cannot create FMOD::Sound instance for clip "" (FMOD error: Error loading file. )
The good file plays without any issues.

Both files play in external players, ran both files through file analysis and all the metadata looks correct.
I'm not sure what to do at this point.

UnityWebRequest req = UnityWebRequestMultimedia.GetAudioClip("file://the path".Replace(" ", "%20"), AudioType.MPEG);
req.SendWebRequest();

    var clip = DownloadHandlerAudioClip.GetContent(req);
    if (clip.length == 0)
    {
        Debug.LogError("bad file failed");
    }

[zinc parrot]

so I use async tasks to use multithreading, but I forgot how I used to effectively deep profile specific parts in the async task functions. Whats the proper way to profile these on the CPU?
I have also been having difficulty with finding info on this for specifically async tasks, as I often get a bunch of less than useful stuff not actually relating to tasks themselves

[knotty sun]

sounds like they were recorded with different codecs, one of which FMOD cannot handle

[smoky atlas]

Looks like there is something wrong with the bad file, tried another site and it can't detect the bad file encoding but it can the good file.
This then would sound like what Elevenlabs is sending back is bad

[knotty sun]

yes, or they are using some kind of custom codec

can you not chose the codec to use for the recording?

anyway probably not a code problem, maybe better in #🔊┃audio

[smoky atlas]

I wasn't not sure the default, maybe something with they. I do have these options:

PCM_24000 looks like the default

[tawny mountain]

Does anyone know if I can Center my line reneder on a navmesh surface?
the rainbow line is what gets generated , the black line would be what im trying to achieve , the clean corners

[knotty sun]

MP3-44100-x (probably 128) would be more common

[lean sail]

Well the line renderer is based on the navmesh path I assume, so really you can do whatever you want in regards to the line renderer. In terms of the path, it calculates an optimal path, what you've drawn is not optimal so it will not get this result. You'll have to implement your own solution

[tawny mountain]

ok , on to google to see what I can figure out

thankyou

yeah srry iknow

https://gdl.space/apetohipob.cpp does anybody have any idea why the camera doesnt just clamp between the 2 values?

[knotty sun]

rotation is a Quaternion, you are treating it as an Euler

[smoky atlas]

Updated to MP3-44100-128, same issues.
I'm going to reach out to elevenlabs.

[tawny mountain]

so It's not the line renderer I create my soulition for , It would be the navmesh path , keeping the corners (the points where the line turns) twards the center or more lined up right?

[undone prism]

i mean thats the only thing i can find on the internet on how to do it like every forum has this line code to use for limiting the rotation so i thought this was the right way. what can i use to make this work? bc im kinda lost tbh

[knotty sun]

this
Mathf.Clamp(cam.transform.rotation.x
is never gonna work because .x is a Quat value

[quartz folio]

Really shouldn't be trying to clamp values read from a transform's Euler rotation either. You should track and clamp your own values that are then applied to the transform

Or, better yet, use Cinemachine and don't write your own camera controller

[lean sail]

Up to you, if you want the agent to move along the exact same "centered" path then yea itll have to be solved for the path.

hi, im making a room spawn system that spawns a series of rooms in a random order, the way i have it done is for each room theres an empty game object (or more) called room connectors. these spawn other rooms at their position and rotation. the problem is that some rooms have room connectors on all sides, and sometimes (most of the times) some rooms end up clipping through eachother. heres a pic and the code. if theres a way to do it without a grid system then that would be amazing, this is what ive been trying but i cant get it to work. if anyone has any idea why please tell.
https://pastebin.com/GiGX91Cs

[hexed pecan]

You could do a Physics.CheckBox/OverlapBox or some other physics query to detect if a space is taken

Or even Rect.Overlaps if you convert the XZ coordinates into 2D rects (and the rooms are never rotated)

Or Bounds.Intersects if you need verticality

[regal oak]

Hello! I want to make a game with PCG platforms. The 'routes' will be created out of chunks of platforms/blocks(4 types to be exact for now) and they all square. By chunks I mean there will be different widths and lengths to them and they will have a route(doesn't have to be straight for or fully filled with max width of blocks and length.
Anyways, does anyone have an Idea how and where can I find algorithms for these kind of PCG?

[half sphinx]

thats what im doing

i linked the code

[hexed pecan]

Oh I missed that

Checking the rotation with == seems a bit sketchy. Not sure if that is reliable

This etc. roomConnPos.rotation==Quaternion.Euler(0,-90,0)

Looks like you have the "edge case" log which would inform you if anything went wrong. Does that ever log?

[half sphinx]

nop

[half sphinx]

how should i check it then

[hexed pecan]

Not sure, I would personally probably store it in a simple variable like a float (y angle) or an enum

The way you are doing it might be fine though.

One thing that comes to mind is that you might have to call Physics.SyncTransforms after spawning a room

[half sphinx]

oh, ill try that

[hexed pecan]

I also suggest that you confirm that your OverlapBox is correct

With Gizmos.DrawCube or something like that

[half sphinx]

yeah thats what i was gonna ask

how to do that

cuz ive been spawning an empty game obj with a box collider and applying the scale snd position manually

[hexed pecan]

OnDrawGizmos, loop your connections and use the same values for Gizmos.DrawCube

Or Gizmos.DrawWireCube

[half sphinx]

okay

[hexed pecan]

Actually it's a bit more complex if your boxes are rotated

Are they?

[half sphinx]

yes

[hexed pecan]

I don't see you taking rotation into account in your overlapbox

That might actually be the reason

[half sphinx]

they spawn with the rotation of the room connection

really?

[hexed pecan]

Yeah your OverlapBox is using a zero rotation by default

Try giving it roomConnPos.rotation

The center needs to be rotated too.

[half sphinx]

how do i do that

[hexed pecan]

You currently have this as center:cs new Vector3(roomConnPos.position.x, roomConnPos.position.y, roomConnPos.position.z+roomDimensionsHalf[i].z*2)
You should do something like:cs roomConnPos.position + roomConnRot * new Vector3(0, 0, roomDimensionsHalf[i].z * 2f)

If I understand your code correctly

[half sphinx]

lemme try

[hexed pecan]

roomConnRot * rotates the vector after it

[smoky atlas]

@knotty sun ended up switching to google's speech to text away from elevenlabs, issue resolved.

[hexed pecan]

You can rotate a vector by multiplying it with a quaternion

[hexed pecan]

@half sphinx See the edit, I added roomConnPos.position

[half sphinx]

yeah i added that too in the code

[hexed pecan]

You have those if-statements just for different rotations, right?

I think you can just get rid of them

And use one OverlapBox that takes rotation into account

[half sphinx]

nothing changed tho, for some context, the scene has a room that has 3 connections, only one room spawns and the console spams cube like 5 times

[half sphinx]

yeah i did that

[hexed pecan]

Try to set up the Gizmos next

@half sphinx When doing procedural stuff, visualization is important so you know what is actually happening

[half sphinx]

https://pastebin.com/w4XC5VDe updated code btw

[half sphinx]

working on it

[hexed pecan]

You need to make sure that the overlap won't hit the 'parent' room too

The one you are connecting to/from

[half sphinx]

yeah thats why i multiply it by 3.9 instead of 4

just to make sure

[hexed pecan]

Alright

[half sphinx]

4 should be a perfect fit tho

[hexed pecan]

I would use 4 and then loop the colliders that OverlapBox returns

Only return true if they aren't the parent room's collider

Alternatively you can disable the parent collider first, then do the check, then re-enable it

[half sphinx]

yeah

but for now

ill get to the point where rooms spawn and then worry abt that

also, how exactly should i draw the box, ondrawgizmos cant take any inputs

wait no

nvm

[hexed pecan]

Oh yeah since you have rotation, you need to use Gizmos.matrix

[half sphinx]

i was just abt to ask that

[hexed pecan]

Gizmos.matrix = Matrix4x4.TRS(pos, rot, Vector3.one);
Gizmos.DrawCube(Vector3.zero, roomScale)```

[half sphinx]

        Gizmos.matrix = Matrix4x4.TRS(roomConnPos.position + roomConnPos.rotation * new Vector3(0, 0, roomDimensionsHalf[i].z * 2f),roomConnPos.rotation, roomDimensionsHalf[i]*3.9f);``` this right?

[hexed pecan]

I edited a bit, maybe easier to set matrix scale to Vector3.one and then draw the cube with the actual scale

Note that DrawCube wants full size, not half size

And it needs to be in OnDrawGizmos (or OnDrawGizmosSelected)

[half sphinx]

so gizmoz.matrix can be anywhere

right

[hexed pecan]

Yeah, think of it like making the gizmos a child of something

After that, everything will be drawn relative to the matrix you gave it

So Vector3.zero as position will actually be the room position you put in the matrix

[half sphinx]

aha

[hexed pecan]

Show the code you used for that

[half sphinx]

https://pastebin.com/Mg1P3Jtt

i think the gizmo is correct

hopefully

[hexed pecan]

The matrix should be set in ondrawgizmos instead

Before you draw

[half sphinx]

yeah but how do i pass roomConnPos to it

[hexed pecan]

Do a foreach loop for the connections

[half sphinx]

ok

[hexed pecan]

And set the matrix again every iteration

[rain bear]

Hi, I'm new to this server. I have a question to ask, should I wait until your conversation is over or can I just throw it out there?

[hexed pecan]

Oh you meant in code, lol. Yeah no

[half sphinx]

    {
        if(started)
        {
            foreach(Transform roomConnPos in roomConncections)
            {
                Gizmos.matrix = Matrix4x4.TRS(roomConnPos.position + roomConnPos.rotation * new Vector3(0, 0, roomDimensionsHalf[i].z * 2f),roomConnPos.rotation,Vector3.one);
            } 
            Gizmos.DrawCube(Vector3.zero, roomDimensionsHalf[1]*2);
        }
    }```

this should work right

[hexed pecan]

Ask away

[hexed pecan]

DrawCube goes inside the loop too

Other than that, it looks ok to me

[rain bear]

Thanks! My issue is with my background animated graphic rendering above my UI text. The background graphic is an empty object containing a LineRenderer script that generates a wave (sine curve). However it obscures my UI text. I used separate Sorting Layers to try to fix it, with the UI sorting layer being above the Background sorting layer - to no avail! Should I post some screen shots?

[half sphinx]

prob the positioning is off now

[hexed pecan]

Also do the * 3.9f multiplication in Gizmos too. Currently you only have * 2. It should be * 2 * 3.9, or whatever is double of the scale you use in the other method

[hexed pecan]

What type of component is the UI text?

Just wondering if it's world space TextMeshPro

Or maybe your canvas is in world space

[rain bear]

It is Text Mesh Pro, I'm using the asset Doozy UI Manager to create all my UI elements. It's a title of Text Mesh Pro inside a View, inside my Canvas which is set to my UI sorting layer.

The UI sorting layer is layer 2, and the Background sorting layer is layer 3, so it should be behind.

Let me check for World Space, that may be the issue.

The Canvas is set to Screen Space - Camera.

I don't see anything on the LineRenderer object showing world space or screen space.

[half sphinx]

2* is actually the correct size , its just off a bit

[hexed pecan]

Alright, well now you have the tools and knowledge how to debug it further

Since you can see what's going on

I hope the gizmos are correct, I'm pretty sure they are

[rain bear]

Actually, there is a checkbox on the LineRenderer that says Use World Space, and that's checked.

[hexed pecan]

Yeah that's fine

[rain bear]

Unchecking it didn't make any difference.

[hexed pecan]

I was asking about TextMeshPro because there are two types, one for UI and one for world space UI

And AFAIK a linerenderer should always render behind normal UI (which is what you want, right?)

Might depend on the material on it, though.

[rain bear]

Yes, I want the line renderer to render behind UI

The pink curve should be behind the UI text.

How do I check which type of TextMeshPro I'm using?

I'm happy to change the material on anything if it helps.

[hexed pecan]

Show the inspector of the object that has it

[rain bear]

This is the Title that renders behind the LineRenderer

[hexed pecan]

Yeah that's the UI version which is fine. I don't know, could be something related to the asset you mentioned. Ask in #📲┃ui-ux instead, this is a code channel anyway 😄

[rain bear]

This is my Hierarchy, the Wave01 object at the bottom is the LineRenderer that makes the curve.

[hexed pecan]

Hmm so the linerenderer is a child of the canvas?

[rain bear]

Ok, thanks!

No, it's outside of the Canvas.

I tried putting it inside the View and it didn't make any difference.

Everything from EventSystem down is outside of the Canvas.

[hexed pecan]

Ah yeah, I was just looking at it crooked

Anyway yeah #📲┃ui-ux

[rain bear]

Okay, thanks for your time.

[half sphinx]

they should be now, i hope, still some weird behaviour happening but ill try again tomorrow

but if that still doesn't work and i give up on physics.overlap, are there any other options

[swift falcon]

Is there a way to pull a vector2 and tell what direction that character is moving? I am trying to set up an animation to change from left to right and the character moves on the following code:

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

[RequireComponent(typeof(Rigidbody2D))]

public class Movement : MonoBehaviour
{
    public float speed = 8.0f;
    public float speedMultiplier = 1.0f;
    public Vector2 initialDirection;
    public LayerMask obstacle;

    public Rigidbody2D rigidbody{get; private set;}

    public Vector2 direction {get; private set;}
    public Vector2 nextDirection {get; private set;}
    public Vector3 startingPosition {get; private set;}

    private void Awake()
    {
        this.rigidbody = GetComponent<Rigidbody2D>();
        this.startingPosition = this.transform.position;
    }

    private void Start()
    {
        ResetState();
    }

    public void ResetState()
    {
        this.speedMultiplier = 1.0f;
        this.direction =  this.initialDirection;
        this.transform.position = this.startingPosition;
        this.rigidbody.isKinematic = false;
        this.enabled = true;
    }

    private void Update()
    {
        if (this.nextDirection != Vector2.zero) 
        {
            SetDirection(this.nextDirection);
        }            
    }

    private void FixedUpdate()
    {
        Vector2 position = this.rigidbody.position;
        Vector2 translation = this.direction * this.speed * this.speedMultiplier * Time.fixedDeltaTime;
        this.rigidbody.MovePosition(position +  translation);
    }

    public void SetDirection(Vector2 direction, bool forced = false)
    {
        if (forced || !Occupied(direction))
        {
            this.direction = direction;
            this.nextDirection = Vector2.zero;
        }
        else
        {
            this.nextDirection = direction;
        }
    }

    public bool Occupied(Vector2 direction)
    {
        RaycastHit2D hit = Physics2D.BoxCast(this.transform.position, Vector2.one * 0.75f, 0.0f, direction, 1.5f, this.obstacle);
        return hit.collider != null;
    }
}

I want to make a new piece of code and just get the vector in order to set the animation each time the direction swaps from left to right but trying to print the Vector2 value in a debug log didn't enlighten me as to how best to do that.

[zenith estuary]

[cosmic rain]

What vector safe you talking about? Where do you debug it?

[quartz folio]

Type normally. This title-case stuff is obnoxious and unreadable.

[untold hemlock]

ok

So I have a game where you can shrink and grow. The scale is set via a script. You can also spawn props like a crate and chair. But when you spawn props that are a different size the contact offset in unity by default does not change. I tried changing the collider offset still no change. This causes OnCollisionEnter to fire way to early ruining the effect of a sound when it hits the ground. When the prop is small the radius is too big, when the prop is big the radius is too small. I am using Unity version 2021.3.26, my colliders are mesh colliders that are convex and I am changing the values by an array of colliders (private Collider[] colliders).

[cosmic rain]

What do you mean by a "contact offset"?

[untold hemlock]

If you go to physics in the project settings there is a setting named default contact offset. You can set this via a collider reference.

[cosmic rain]

I'm not sure how that setting is relevant to anything..?

*to your issue

[untold hemlock]

It's basically when the collider point is less than the distance. It calls stuff like OnCollisionEnter. And I use that to make a sound when the object collides with the ground. But when the object is small it does not change causing the collision to detect to early. I tried setting the colliders contact offset via script and it did nothing.

[cosmic rain]

Why would your colliders be smaller than .01 units..?

I'm sure that's gonna break more things than just the collision events.

And if not, it should really make any difference at all. .01 is a very small distance.

[celest musk]

hello, im looking for some help with my game to get my enemy to move and attack the player if someone can help me that would be great

[cosmic rain]

What's the issue and what do you have so far?

[swift falcon]

I had attached a debug log just to get the direction for that specific character and print it but I think I did so incorrectly. I'm not really the programmer, I'm just supposed to implementing animations here. The vector I though I could use was the one named "direction". Sorry for slow reply, got busy with other stuff.

[cosmic rain]

I don't see you a debug log anywhere in the code you shared, so I can't say if it was correct or not.

[eager cliff]

I have tested in new scene and the test show. What could be the problem in my original scene?

[celest musk]

the character doesnt move or it will walk into a object and stop moving

[cosmic rain]

Share the relevant code.

[swift falcon]

Yeah we had to revert the code due to a github merge corrupting some stuff, but basically it's a generic movement script attached to 4 different characters, and it most likely wasn't correct. What would be the best way to go about writing a debug log for one of the characters it's attached to?

[cosmic rain]

Make a check if it's the character you expect and debug if it is.

[swift falcon]

Got it, thank you.

How would I get this kind of behaviour without parenting?
Where it follows the point, at an offset. It also rotates with that point, keeping that offset.

but the rotation has me stumped

Hey guys 👋 im trying to add ground detection through raycast but my current logic uses on collision. i am for some reason having trouble separating grounded logic from on collision.

private void OnCollisionStay(Collision other)
{
    // Make sure we are only checking for walkable layers
    int layer = other.gameObject.layer;

    if ((int)whatIsGround != ((int)whatIsGround | (1 << layer)))
    {
        // If the collision is not with a walkable layer, exit the method
        return;
    }
    
    for (int i = 0; i < other.contactCount; i++)
    {
        Vector3 normal = other.contacts[i].normal;

        // Check if the collision is with a floor
        if (IsFloor(normal))
        {
            // If wall running was active, disable it
            if (wallRunning)
            {
                wallRunning = false;
            }
            grounded = true;
            normalVector = normal;
            cancellingGrounded = false;
            CancelInvoke("StopGrounded");
        }

Looks like you have a lot of different logic happening there (grounded, wall stuff, surfing stuff), I would try to move each of those into their own functions, if youd rather use a raycast instead of a collision check, often youd do those ray checks frequently, such as in Update or FixedUpdate, and in the Physics class, some raycast calls return a bool if it hit anything, if performance is a concern, you can also use non-alloc versions which return a number of hits instead of if anything was hit - see the "Static Methods" section: https://docs.unity3d.com/ScriptReference/Physics.html

For example, a typical setup might look like this:

bool isGrounded;

void Update()
{
GroundCheck();
}

void GroundCheck()
{
isGrounded = Physics.Raycast(...);
if (isGrounded) { DoGroundStuff(); }
}

You could even use another bool to track when "isGrounded" and the other bool differ, set them to the same value, then fire an event if you want to do logic on the frame that the player becomes grounded, not sure if that helps - one other note about .Raycast, is it is a single line in a direction, so cases like literally standing on edges or slopes may cause strange results depending on the origin of the cast, for those cases there is also things like .SphereCast or .BoxCast, depending on the accuracy you need, sadly visualizing the cast is a bit tricky, as youd either need to use OnDrawGizmos or Vertxyz's debugger package for anything that is not a simple ray, for that you can use Debug.DrawRay or Debug.DrawLine, which may be useful for Physics.Linecast - also, something that may help, if you prefer, you can assign layers through the inspector with a LayerMask type

[runic nimbus]

What terrible advice. Yeah turn the script into a maze of one use methods.
I can only comment on the formatting, and the only thing I would change is the new line brackets and comment spacing.
Here, -20 lines - https://gdl.space/bujoperohu.cpp

Doesn't look all that crazy when you can see the whole method without scrolling. New line brackets bloat up code and make it less readable.

[soft shard]

Im not sure I understand your concern? It sounded like OP wanted to change from using OnCollisionStay to using raycasts, and it looks like his current logic has several different things beyond just a ground check happening, which can be confusing, my suggestion is to put those into functions so its easier to manage, im not sure how that is a bad thing? I may be misunderstanding what your concern is, but it seems like you are just concerned about the bracket formatting in the example provided? Im not sure I get whats "terrible" about this, could you elaborate?

[runic nimbus]

I don't agree with the idea of creating methods that are only used in one place. If you're gonna do that, you're essentially naming the code. Thats what comments are for.

void Update() { // Terrible
  Shit();
  Piss();
}```

Instead, because I do agree the script looks messy, you can apply some basic formatting to make the script a lot shorter than it was. Then it looks much more digestable without those one-use methods everywhere.

[lean sail]

I don't agree with the idea of creating methods that are only used in one place
This is very commonly done for readability

[lunar python]

readability and maintainability

[runic nimbus]

yeah and I disagree

[runic nimbus]

No idea how that would make your code more maintainable

[lean sail]

🤷‍♂️ you can disagree but its whats commonly done in professional environments

[runic nimbus]

Professional code sucks ass. Have you ever looked at Unity's scripts?

Photon's scripts? Any large professional library's scripts?

They're horrible beyond comprehension.

[lean sail]

i dont get your point, you'd rather all the code in one giant block? Thats your preference, do what you want in your own projects. you'll not get far in professional environments

this is just a matter of you not wanting to write it in a nice way

[rigid island]

troll?

[runic nimbus]

This is what you're advocating for

[lean sail]

probably just a rebellious junior

[runic nimbus]

C# programmer of 3 years

[lean sail]

yes, so a junior

[runic nimbus]

Not a newbie though. I've finished several projects and come to that conclusion.

[lean sail]

this is all that needs to be said about it

[rigid island]

reminds me of my friend who codes like shit to make his own code unintelligible so he's hard to replace (only he understands his bad code)

[lean sail]

goodluck in the real world with your mentality

[runic nimbus]

And this is my response. The words you say disconnect when you try to put it in code.

In no world is the one on the right more readble, "nicer", or more maintainable

You're just naming the code and making it longer.

[lean sail]

and why is making it longer an issue

[soft shard]

Typically, code would follow "S.O.L.I.D", I dont personally believe that comments should be used to organize or describe code, unless it actually adds value (such as explaining a math formula being used) - if I have a character controller, I would rather have a function for each part of my code, a function for input polling, a function for ground checks, a function for movement, jumping, abilities, etc, (or possibly states) rather than everything in Update organized by comments (which is the S of solid, single responsibility), I guess in a way thats "naming code" but you can also have your entire project on a single line of code in 1 script, itll just be impossible to debug or add features to, but it may come down to preference in code style

[runic nimbus]

Less readable. Longer code takes up more space and it worse to work with.

You should always strive to make your code as short as possible so long as it doesn't impede readability

[lean sail]

"takes more space" yea i dont wanna entertain this anymore.

[rigid island]

says random dude with 3 years exp vs those with many years in industry

[lean sail]

that is absolute dogshit advice

[rigid island]

you're wacked out

[runic nimbus]

not disk space, brain space

[rigid island]

thats the stupidest point i've heard in a while

[runic nimbus]

Works on my machine

[lean sail]

we're just being trolled at this point

[rigid island]

fr

someone makes these statements have to be trolling or have 0 clue what they're talking about, which goes well with former

[runic nimbus]

Yeah, 1 thing. I guess that just comes down what you consider 1 thing to be. I think handling jump, move, and turning in a character controller is all a good thing to bundle up in 1 method. So long as that 1 thing doesnt exceed 70-80 lines I think its okay (especially if it's compact/dense code)

[rigid island]

less lines doesn't mean better or more legible code..

[runic nimbus]

Say what you guys want. The less your eyes have to move around the script the more readable it is. That's how it's always been in my experience. Short code is readable code.

[rigid island]

thats like saying driving a car with a binocular is better than your own two eyes because is less for your brain to process 🤔

[runic nimbus]

Completely broken analogy

[rigid island]

you're talking about eye movement as your point

thats nonsense

[runic nimbus]

When trying to analyze a script it is simply easier to analyze less.

If the street was smaller, of course it's easier to drive.

[rigid island]

some people can't read well LINQ and thats less lines, what are you talking about

less doesn't always mean better

[runic nimbus]

Of course it doesn't always mean better

Nothing always means better

But in my expereince the shorter you can get a script down to, usually measured by lines, the easier it becomes to maintian because you are simply maintaining less.

Here's one of my scripts that handles weapon handling. Look at all of that well sectioned and "named" code that you don't need to jump around to find!

Ignore the fields

[lean sail]

consider that you said "comes down what you consider 1 thing to be" and then you said "handling jump, move, and turning in a character controller is all a good thing to bundle up in 1 method"

[rigid island]

messy

[runic nimbus]

yeah, that "1 thing" is basic player body controls

[lean sail]

ok and my 1 thing is just my game

do i put it all in 1 script?

[runic nimbus]

There's a hard limit because sometimes you actually need methods for their intended purpose, to reduce duplicate code. So no, at some point you would have to divide it into sections.

Classes too

[lean sail]

anyways your code really isnt readable either

[runic nimbus]

Aww

guess I'll go blind now

I love my code. That's probably my proudest script.

[rigid island]

so much to learn 🥹

[runic nimbus]

If I ever need to change something about recoil, I'll go to the big green line that says "Weapon Recoil" and change it

while you guys keep bickering about maintainability or something

"Go back to your code after 3 months and tell us if you understand anything" GDL said... those snobs.

[soft shard]

At this point I think this is "agree to disagree", we both have different philosophies for how we see code, I use functions to separate logic in my code instead of comments, I can see your view, I just disagree with it, it would be a hinderance to code that way for me, simply because of how I see "1 method" differently than you do, but thats because my brain prefers to see separation of logic rather than one big thing and ive adapted to scanning code that way, I look for a "recoil" function or class rather than a comment containing the words "recoil" in it - its also nice having the ability to comment or condition a function rather than several lines, but we may just not see code the same way

[lunar python]

shorter doesnt mean more maintainability

how do we even cope with this

[runic nimbus]

Yeah, this is fair.

[runic nimbus]

Anyways, a few pages ago I actually asked a question. Gonna bump it now, help would be appreciated.

[lunar python]

I did competitive programming and we could do the entire program in a few lines with alphabetical variable naming. That is horrible for any team to work on.

idk if you have been in any coding team whatsoever

[runic nimbus]

Have not. Code golf goes far beyond the reasonable assumption of what I mean by "short code" though.

[sage latch]

I dont know the answer to your question, but just here to say I for one 100% agree with you on the code style stuff

Also a thing I noticed is that I also use implicit private modifiers and braces on the same line :D

This is an example of what happens when you make a method for everything (from a project I worked on with a team)
https://hatebin.com/vadfbffeja

[sullen drift]

i have a question, could you access a static varible from another script on another scene that havent be loaded?\

[sage latch]

Yes

[west lotus]

What no

[lean sail]

your scripts have nothing to do with the scene. A static variable is associated with the type, not the instance

[west lotus]

If the scene is not loaded you aint accessing shit from it

[sage latch]

Static members always exist

[lean sail]

static

[sullen drift]

okay, then it should be fine. Im transfering a list of data into a static list from another script in another scene. Just trying to make sure i could access it. Thank you then

[lean sail]

whats the data? seems like an odd use case to need static here

[west lotus]

My bad I jumped the gun here

[sage latch]

Just make sure it isn't null. You cant initialize it from Awake or Start as they are not going to be called, so you have to do it like this:
public static List<...> ... = new List<...>();

[sullen drift]

Im creating a fishing minigame for an rpg game. Lets say there are many fish areas that have their own certain type of fish. I already have a list of fish in every areas accordingly, so every time the player click the fish area, those list will be transfered to the minigame script that has a static list variable to contain the previous fishes. Its for the reward ramdomizer

[sullen drift]

okay gotcha

[lean sail]

as long as you're aware of how static works, you can make this work. it just may have some downsides that are annoying to debug. I would maybe go for a singleton instead so you can have a method that allows you to pass in a list and also startup the scene along with anything else thats needed. This way you can try to enforce what happens all in one place.

Not really much different, but it'd basically protect you from a friend (or yourself in the future) from changing the public static list when its not meant to be changed, and then wondering why the whole minigame stopped working

[sullen drift]

yeah, actually ive been thinking to make a singleton, but lets say some architectures from my lead programmer doesnt want me to do that hahaha (i know its weird)

[west lotus]

If he doesnt want you using a singleton he will for sure not want you to use a unprotected static field in a class

[lean sail]

yea weird, considering a singleton is basically just a static reference to the instance. the public static list is way worse

[west lotus]

Must one of the people who saw online “Singleton Bad” and now just parrots this sentiment

[sullen drift]

i already think a way to protect it, no problem

[lean sail]

a different way would be have a game manager. This creates the minigame manager (whatever you wanna call it). Then you create fishing areas, pass the minigame manager to a script on the fishing areas. On click, do whatever you need

[sage latch]

Or make a scriptable object 🙃

[latent latch]

singletons are a much cleaner architecture than most static alternatives since you can control its lifetime between scenes

[merry stream]

can anyone point me in the right direction to be able to save scriptable objects to json using newtonsoft

[fervent coyote]

Okay, so I'm using

AudioSourceObj.volume = 0.01f, and even through debugging proving it is set to 0.01, it STILL. IS. 1!!

Can someone please help me figure out why is is reverting to one?

[latent latch]

are you ever writing to scriptable objects

or is it readonly data

[merry stream]

i am writing to them, using them as an inventory

[cold egret]

• I have a transform and a vector3 that represents a local position within the transform. What is the most efficient way to get a matrix4x4 that ocrresponds to that position?

[fervent coyote]

When I set the volume to 0 in script, it mutes it. It seems it can only be between 0 and 1

[latent latch]

well, you'd tackle it like any other way you'd save data, but if you're appending data over some sort of defaults then you can just use the ID of the scriptable object and then write create a few structs to write the more unique data.

[merry stream]

well doesnt the ID of the SO change so serializing that would be useless

you cant save references to SO's i thought

[latent latch]

if you're using SOs and creating variations using the asset context menu, then you're creating different variations of defaults of the script. If you were to keep track of these by ID, you can probably save yourself from serializing more data than you need to, but you still need to serialize all the data in which you write to. An example would be writing to a weapon SO, you'd write the damage values if you are to modify them, but it's not likely to modify the sprite, so you might as well just load it from the SO.

just depends how you're using them is the question, but if you're using SOs to write data to, I'd assume you have some specific set already when making copies of it

otherwise you'd just use plain ol' c# scripts

[lean sail]

https://docs.unity3d.com/ScriptReference/Matrix4x4.Translate.html

is that what you want?

[lean sail]

for simplicity i would just save using poco. I dont see why you would want SO in this case

[latent latch]

do yo mean to just use transformpoint and create a 4x4 from that ?

[merry stream]

what do you mean by POCO?

[lean sail]

plain c# script

[half sphinx]

I just did it!

it works now!

ty for helping me

400 rooms!

[knotty sun]

neat, it would be nicer if you had multiple paths though

[half sphinx]

well, the number of paths solely depends on the chance of a big room spawning, which has 3 room connections, meaning itll spawn 3 rooms in different directions, if it has space

[knotty sun]

what I meant was, if you look at your map and select any 2 points on it there is always only one path between them

[half sphinx]

ohhh i see

[knotty sun]

but a damn good effort none the less

[merry stream]

how could I give a scriptable object a unique guid that is assigned once and can not be changed?

[latent latch]

unity assigns an asset ID to one, but you can just generate your own otherwise

[soft shard]

Whats your use case where a SO might need a unique ID? Why might you not be able to use the SO itself? Assuming you likely would have unique SO's to begin with (for example, you probably wouldnt have 2 of the same weapon), or are you trying to generate SO's of a certain type with a editor script or something similar?

[latent latch]

for saving and loading asset presets

[soft shard]

Wouldnt you still be able to use the SO itself?

[latent latch]

well, how would you write that to JSON and load from

you can either write by the path, or the easier way, an ID that's mapped to that path

[soft shard]

Ah I see, in that case if the SO is being saved to JSON or something that isnt an asset in the project, then I can see generating a guid for each SO

[lyric panther]

when i read transform.localrotation.x it goes from 0-360 but in the inspector and also while setting it via "transform.localrotation.x" it's diffrent. when looking up it reads 270 but in the inspector it's -90. how do i read what the inspector's seeing?

[latent latch]

When you create an SO instance from the asset context menu, you're creating a copy which you can define different values to, though it's not a different type. This makes serializing by type not the solution if that's what you're thinking of, but assuming you do want to write to the SOs and serialize all its data, then yes you can probably do that.

Though, the idea of IDing the SOs is that you're not always overwriting (personally I never write to SOs) the data in the SO, so why serialize data when you can just make a lookup for your SOs and load it from there?

Similarly to prefabs, you wouldn't serialize prefabs completely, you'd have a manager that handles the construction of these assets which is defined by IDs.

[lean sail]

Local rotation is a quaternion. Assigning directly to the X component will not give you what you think. Anyways -90 and 270 are the same angle. You cannot read back this same because you give it euler, unity stores as quaternion, inspector shows it as euler so it must convert back. Sometimes it gives you a different set of angles but equaling the same rotation

[lyric panther]

so if i just read localrotation.x it'll show what it says in the inspector?

[lean sail]

No because it is a quaternion

[lean sail]

If you absolutely need to keep track of some euler angles, store your own version of them in the script and do your operations there. Using the .rotation will suffer from what I said about it being shown back as different values.

If you can work purely with quaternion it is better so you dont need to have your own local euler system going on

[soft shard]

Right, I usually use SO's as "blueprints" so for example I might have a SO that creates weapons, but id likely not have 2 "glock 18"s, even if I have 2 "pistolSO", I can see if your trying to save a serialized class inside the SO to file file to load into a SO instance (weather you save that back as an asset or just use it at runtime) make sense, otherwise if the SO is already in your project assets, I agree having a lookup of some sort makes sense but I cant see a reason to save the SO in a different form/JSON/etc outside the project, maybe I misunderstood something there

[lyric panther]

I have a value that sets the x euler angle, when that value is -90 the camera looks up, but when i read the localrotation euler angles it's 270, I just need to read the localrotation so i can get that same measrement

[latent latch]

How do you define between a glock 18 and another pistol that's also an instance pistolSO then?

unless you're writing all data from that SO type then deserializing it as a pistolSO then there wouldn't be ambiguity, but then you're required to update the whole base SO with those values

[lean sail]

Did you miss my message above? I told you exactly why this happens and what to do about it

[lyric panther]

you really didn't

[lean sail]

I did, if you didnt understand something then you can ask me to clarify. But reposting the question really isnt gonna get you a different answer

[lyric panther]

I thought i clarified enough

i've found the answer, it was this

[lean sail]

I have a feeling like you arent properly reading my messages. I said you can ask me to clarify

[lyric panther]

sorry it's really late and i've been coding all day

I applogise for being snarking

snarky

[lean sail]

Anyways that alone is not a solution to the real issue at hand, I dont even think quaternion will return an euler value greater than 360

[lyric panther]

that solution works for my use cases tho

the rotation is clamped from -90 to 90

it's a fps camera thing

[lean sail]

It's better if you just store the angle that it should be as I wrote here #archived-code-general message
Theres no point really assigning it to the rotation, having it convert to quaternion, converting it back to euler, sending it through this function, then getting the result. Compared to just storing it and already having what it should be

[lyric panther]

I'm manually rotating the camera in another script, so when i finish rotating it i need to know what i need to set the variable that's moving the camera in the fps controller

[lean sail]

Though if it works then 🤷‍♂️ carry on. I feel like there are edge cases where this might not work but I am too tired to think of an example right now

[lyric panther]

if there are edge cases, i'll cross that bridge when it comes to it

[soft shard]

Maybe it depends on how the SO is used, I often use them like this:

[CreateAssetMenu(...)]
public class SomeSO : ScriptableObject
{
public SomeData data;
}

[System.Serializable]
public class SomeData
{
//pistol data, damage, ammo, etc...
}

For myself, I would be saving SomeData to JSON, and loading that into a SomeSO instance if I needed it, I personally have not tried saving the entire SO itself, though SomeSO in this case would be the "PistolSO" or "WeaponSO", etc

[lean sail]

You can see the cases quickly if you manually assign rotations in inspector. I believe if you put (0, 180, 0), itll automatically give you back (180, 0, 180). I dont remember the exact case but it was something like that where you get back an equal rotation but widely different numbers

[lyric panther]

I'm not manually setting it in the inspector I'm manually setting it via "transform.localrotation = quaternion.eulerangles()"

[latent latch]

Right, it depends on the requirements, but think of a game like maybe classic doom where your gun is always the same damage, same reload speed, same capacity. There you wouldn't care to serialize all that data beyond something like your current ammo (and the ID foremost).

[lean sail]

I know, I was just saying you can quickly see the issue by doing it in inspector. It is the same by giving it euler values through code

Quaternions are on too high a level for my understanding lol, I'll just use Euler's in the meantime

[frosty snow]

what parts of this can be executed on a background thread ?

eg, gameObject property must be called on the main thread, but what else must be called on the main thread ?

[cosmic rain]

Probably none.

And even if it could, you probably shouldn't.

[frosty snow]

why

i want to try to avoid getting stutters on the main thread when instantiating my ui

[fervent furnace]

anthing that not interact with scene

eg Debug.Log

[cosmic rain]

1. There's no reason to.
2. You don't wanna mess with threads too much.
3. Overhead?

[frosty snow]

eg, can i build UI components in the background and then attach them to my scene on the main thread ?

[cosmic rain]

I have some recollection of debugs not working on a background thread.

[frosty snow]

Debug.Log does work in any thread

[cosmic rain]

Hmm... Must be fake memories then.

[frosty snow]

anyway can i do this ?

eg

        RunOnBackground(() => {
            // build UI in background
            UnityEngine.UIElements.Button button1 = new();
            UnityEngine.UIElements.Button button2 = new();
            button1.clicked += () => button1.text = "CLICKED";
            button2.clicked += () => button2.text = "CLICKED";
            RunOnMain(() => {
                // attach UI in foreground
                ui.rootVisualElement.Add(button1);
                ui.rootVisualElement.Add(button2);
            });
        });

[cosmic rain]

I wouldn't be surprised if it's not possible, but you can try and see 🤷‍♂️

[fervent furnace]

i doubt when you new a uielement you are interacting with the scene

Btw check if some calls are interacting with the scene not a strict test to indicate if the call can be called in background

[quartz folio]

As with anything Unity, it matters whether the implementation is interacting with the engine in a way that isn't thread-safe, which is a lot of the native APIs. Luckily UITK is implemented a lot more in managed land... But not all of it. So might have mixed results, and due to a lot being event based, it could trigger different things with minor changes

The answer is try it and see, and the longer answer is, even if it does work it doesn't sound robust to change

                currentFrame = nextFrame;
                nextFrame = tmp;
            }
            while (currentFrame.TryDequeue(out var action)) {
                action();
            }
        }
    }

would this do?

[knotty sun]

var tmp = currentFrame;
                currentFrame = nextFrame;
                nextFrame = currentFrame;

whoops

[scarlet viper]

so confusing to read

[frosty snow]

                // swap action buffers
                var tmp = nextFrame;
                nextFrame = currentFrame;
                currentFrame = tmp;

this maybe ?

[knotty sun]

no, thats the wrong way round, you had it right before

actually no you didnt

[frosty snow]

rip

what would be the correct way to swap two objects

[knotty sun]

currentFrame = nextFrame;
                nextFrame = new();

you dont need to swap

[frosty snow]

that would incur allocation overhead

[knotty sun]

this is correct

var tmp = currentFrame;
                currentFrame = nextFrame;
                nextFrame = tmp;

currentFrame should be empty at this point

so you swap an empty queue for a full one

[half sphinx]

i see 2 ways of doing this: 1. have some room models that loop around and stuff like that and 2. instead of not placing a room, make a procedural connection part that connects 2 rooms

but ill go with 1

[knotty sun]

what I would do is look to see if there is already a potential connecting room and limit the room generation so it gets a connection

[half sphinx]

true thats also something

but it prob wouldn't happen so often

unless yea i limit the generation

ill see

[knotty sun]

you're on the right track though, good proc gen is hard

and then comes the fun of doing it in real time

[frosty snow]

yea

                // swap action buffers
                var tmp = nextFrame; // full
                nextFrame = currentFrame; // full = empty
                currentFrame = tmp; // empty = full

[knotty sun]

exactly

[frosty snow]

also changed to

        public void RunOnBackground(Action<object> action) {
            Task.Run(() => action(action));
        }

        public void RunOnMain(Action<object> action) {
            nextFrame.Enqueue(action);
        }

        public void RunOnMain(object action) => RunOnMain((Action<object>)action);

so we can do RunOnMain(r => RunOnMain(r)); // repeat every frame

RunOnBackground(r => RunOnBackground(r)); might be a bad idea tho, since doing such would basically be

while(true) {
    Thread.run(() => {});
}
```which would probably be expensive and a thread pool may deadlock while adding a thread while running an existing thread if all threads happen to do so

T1 add T1 // thread 1 runs and re-adds itself to the pool
T2 add T2 // thread 2 runs and re-adds itself to the pool
deadlock, cannot add thread, capacity 2, active 2, both T1 and T2 cannot exit until a thread has been added, but a thread cannot be added until one has ended

[knotty sun]

still not sure what you hope to achieve with this

[fervent furnace]

swapping the queue should be slightly faster then using one concurrency queue at all.....just little bit since the worker still need to process all the task at first but he dont need to get the lock when dequeue

[frosty snow]

yea

it also avoids endlessly running the same task

eg

we deque task 1
task 1 runs
task 1 queues itself
we deque task 1
...

[fervent furnace]

why the task one can dequeue itself

[knotty sun]

but why? it seems like you are building a game engine within a game engine

[frosty snow]

a task may wish to run itself every frame for whatever reason, or tasks may wish to run other tasks

for example, a layout engine may need to postpone its layout until the next frame due to a change

idk

[fervent furnace]

you worker should be

public void Enqueue()
private void Work(){
  while(true){
    if(queue.tryDqueue(out work)){
      work();
    }
  }
}
```obviously the work can enqueue itself to the queue but it cannot call work() on your worker

btw this is simple consumer-producer model

[frosty snow]

i know

[scarlet viper]

i have a silly code design problem, there are 2 approaches ive tried to a problem:

1. put engine code on Engine Monobehaviour script, etc, reference engines etc from Car class
2. create separate non-mono classes for engine functionalities like throttle etc and reference them from a car (instead of engine)

with 2. i can edit these things just when i have my car selected and i dont need to search for engine and other children in car transform hierarchy
its so much better to debug
but i think it shouldnt be like this, these variables should probably go to Engine since theyre engine related

I guess i can just put them in engine and make it all Serialized so that i can edit them from the main car script inspector

[latent latch]

It probably would make most sense on the gameobject that's driving that specific instance

and for that it must be a mono

Ideally you'd have a Car script on the Mono too which includes an instance of Engine so this way you just need to have a reference to the Car to access Engine

In that case you wouldn't need Engine as a Mono since it's the Car script that's on the gameobject

So yeah, I believe it aligns with your number 2 suggestion

Unless you have a physical model for the engine (which could be damaged), then it could make sense for it to also be a mono

[frail thorn]

Anyone know how to work with AR?

[eager steppe]

Just wondering if anyone knows how to get the x position of my mouse click, when it clicks on an object that is scrollable?
My object is contained within a scrollrect, with a scrollbar controlling where we are on the timeline. When i click on a place on the object, I want the song time to skip to there, but how do I do that when I won't know where I am within the current bounds of the scrollbar?

shouldnt i have gotten at least a compile error ? o.o

[frosty snow]

welp i definitely get a compile error with this

(27,16): error CS1061: 'ScriptManager.ThreadRunner' does not contain a definition for 'aRunOnMain' and no accessible extension method 'aRunOnMain' accepting a first argument of type 'ScriptManager.ThreadRunner' could be found (are you missing a using directive or an assembly reference?)

so thats good

[somber nacelle]

and what is aRunOnMain

[static matrix]

is it possible to add attributes to a predefined unity class?
Like lets say I wanted to add an attribute to LineRenderer Called TargetPosition Could I do that?

[deft timber]

you cannot directly add attributes to predefined classes

[somber nacelle]

i assume by attribute you are actually referring to a property or variable. but the answer is no either way. at best you can create extension methods

[deft timber]

public class ExtendedLineRenderer : MonoBehaviour
{
    public Vector3 targetPosition;
    private LineRenderer lineRenderer;
}

somight like that might work for you, depending of what will be the use case of targetPosition

[static matrix]

yeah ok good to know
I had hoped there was some way to create extension attributes like extension methods

[somber nacelle]

nope. and keep in mind this isn't java, attributes in c# are something different

[static matrix]

I actually know c# better than I know java heh
or I like to think
maybe I mean properties?
either way, the game working does not hinge on this being a thing
I will just have to write some slightly messy code

[somber nacelle]

you might be able to inherit from LineRenderer (i can't actually find it in the cs reference at the moment to check whether it is sealed or not). or just use some wrapper class that has those desired properties on it and manages the linerenderer component for you using those properties

[deft timber]

you cannot inherit from LineRenderer

you cannot directly inherit from built-in Unity components -> they are all sealed

[heady iris]

I'd just make a component that handles a LineRenderer for you

LineRendererWrangler

maybe pick a more specific name

[frosty snow]

A typo :3

to see if it actually errors

[somber nacelle]

they aren't all sealed. but i was able to find that LineRenderer is in fact one that is sealed

Excellent

i dunno wat i wanna write lol

[static matrix]

functional code :3

[obsidian jasper]

Is it possible to input two buttons for 1 function ?? for example i have public string btndwn; Can i input two buttons in this ??

[static matrix]

what do you mean

[somber nacelle]

if you mean for something like Input.GetButton then no, you need a separate call for each button you want to query

[static matrix]

if(Input.GetKey(KeyCode.A) && Input.GetKey(KeyCode.B){
  Debug.log("Wowhua Two buttons are held");
}

like this?

oops forgor to close string

[obsidian jasper]

ya but i need to use Public string btname so that i can input btn name in inspecttor

[static matrix]

oh you can just do Key I think

theres some Type you can put in the inspector to have a list of all the keys but I cant remember which one it is

[somber nacelle]

if you are querying individual keys, then use a KeyCode rather than a string

[static matrix]

    void SetTargetPos(ref Vector3 TargPos){
        TargPos = transform.position + Random.onUnitSphere;
    }
    Vector3 SetTargetPos2(){
        return transform.position + Random.onUnitSphere;
    }

is there any bearing on which of these two functions would be faster? presuming that the calculation to get the final TargPos will get more complex (raycasts and shtuff)

[obsidian jasper]

public string F_Pause_Game(){return Pause_Game;}```
now i wana input like two keys in the inspector how i do it ??

[static matrix]

Get Functions 🤢
dont like em

[leaden ice]

public KeyCode[] pauseKeys;

void Update() {
  bool pausedPressed = pauseKeys.Any(key => Input.GetKeyDown(key));
}

[static matrix]

do public KeyCode Pause_game;

yeah or this

you are smarter than I Mr.Blue

[static matrix]

also why are you using a Get function when the var is public anyways?

[static matrix]

AAA Lambda jumpscare

I need to learn it better heh

[obsidian jasper]

thanks let me try this

[static matrix]

ref makes me feel smarter I will use that

also something something memory allocation

[heady iris]

don't forget in and out

and, in C#12, ref readonly, the weirdo

[somber nacelle]

there really is no reason that this needs to use ref. just return the value and assign to the variable at the calling site

[heady iris]

the first one is much more confusing to me

I use out when I need to return a success/failure value and communicate a result

[static matrix]

out is like extra return values right?
sorta?

[heady iris]

It's like ref, but it's write-only.

It also demands assignment.

[static matrix]

like a return value

[heady iris]

public bool TryGetThing(string thingKey, out Thing result) {
  if (CanGetThing(thingKey)) 
  {
    result = FindThing(thingKey);
    return true;
  }

  result = default;
  return false;
}

[static matrix]

I see out a lot more in other people's code snippets so maybe I should learn that one instead of ref
idk
back to code writing!

[heady iris]

ref is inferior because:

• it doesn't assure that something is written to the variable
• it implies that the function might care about the variable's contents

ref means you can't do something like...

TryGetThing(string key, out var result);

if you tried to do this instead, you'd get a compile error because result isn't definitely assigned

TryGetThing(string key, ref var result);

[static matrix]

hmmm interesting

[heady iris]

well, it also might just be a compile error for some other reason

maybe you can't even declare a variable in a ref argument at all

but it'd be for the same fundamental reason

[somber nacelle]

i'd assume that would be a compile error

[heady iris]

oh it's definitely a compile error

[static matrix]

 void RecalcFeetPos(ref Vector3 EndPos){
        Debug.Log("TryRecalcFeet");
        var TryPoint = Physics2D.Raycast(transform.position, -(transform.position - (Conv0(transform.position+Random.insideUnitSphere))).normalized, FootLength, ground);
        if(!TryPoint){
           
        }
        else{
           EndPos = TryPoint.point;
        }
        
    }

but for this function I might prefer to use ref as it can be possible for the point to be null

[heady iris]

can't let an uninitialized local variable escape like that (this is not about RecalcFeetPos; i was talking about my code above)

Vector3 can't be null.

This is a perfect application for returning bool and assigning an out parameter.

TryFindFootPosition

[static matrix]

huh well this code works fine

[static matrix]

gave me desired effect which is this
Not saying "oh my code is better you are wrong" more saying "this works for me I might keep it for now"

[heady iris]

I would want to know the difference between "the point didn't change" and "I couldn't find a point at all"

but it's probably close enough

[somber nacelle]

and how does this being a ref parameter instead of either a returned value or out param affect the calling code?

[chilly surge]

If the goal is to mutate a variable in place, then ref is fine. Try pattern is good for "returning result from an action that may or may not succeed"
I do rarely find myself needing to mutate a variable in place though.

[static matrix]

well i think it keeps it from trying to assign the feetpos to null which as Fen stated is something that cannot be done

idk
if it ain't broke clearly there is no room for improvement (trust)

[somber nacelle]

i'd like to see what you're doing at the call site because i'm sure your choice for making this a ref parameter is making you do some weird stuff there and that is also something you should consider when making choices like this

but also it's not preventing the variable from being assigned null because that is not possible at all anyway

[heady iris]

what it is preventing is failing to assign to an out parameter

that would be a compile error, because out parameters must be definitely assigned

undefined != null

Vector3 what;

what is not null

[static matrix]

 feet[0].SetPosition(0, transform.position);       feet[1].SetPosition(0, transform.position);
       feet[2].SetPosition(0, transform.position);
       //Debug.Log(Vector3.Distance(feet[0].GetPosition(0),  feet[0].GetPosition(1)));
        if(Vector3.Distance(transform.position,  feet1Position) > FootLength){
            RecalcFeetPos(ref feet1Position);
        } 
        if(Vector3.Distance(transform.position,  feet2Position) > FootLength){
            RecalcFeetPos(ref feet2Position);
        }   
         if(Vector3.Distance(transform.position,  feet3Position) > FootLength){
            RecalcFeetPos(ref feet3Position);
        }
        feet[0].SetPosition(1, Vector3.Lerp(feet[0].GetPosition(1), feet1Position, 0.08f))       ;
        feet[1].SetPosition(1, Vector3.Lerp(feet[1].GetPosition(1), feet2Position, 0.08f))       ;
        feet[2].SetPosition(1, Vector3.Lerp(feet[2].GetPosition(1), feet3Position, 0.08f))       ;

this is the feetcalc stuff
its somewhat messy
tbh I did not use out because I didn't consider it because I didn't really know how it worked

[fervent kernel]

Hey guys could someone help me with getting OnParticleTrigger to work?
I checked the Triggers module on and all the options to callback.
But the OnParticleTrigger function doesn't actually trigger.

[green ice]

Hi guys,i would change the position of an object at the start method,but later it returns in the original position,do you know why?

[dusk apex]

We wouldn't know without more context but would probably assume that you've got something else changing the position or that you're changing the position of the wrong object.

[fervent kernel]

Anyone experienced with OnParticleTrigger?

[leaden ice]

Have you read the instructions here? https://docs.unity3d.com/Manual/PartSysTriggersModule.html

Which object did you put that script on?

[fervent kernel]

Hey, I put it on a child of a gameobject which has a particle system component.

Don't pay attention to the sphere collider attached, I was running out of ideas as to how to solve this 😄

[leaden ice]

You haven't actually added any triggers here

[fervent kernel]

Wait, so what do I need to put there?

[leaden ice]

To begin, specify which Colliders in the Scene the particles can interact with. To do this, assign one or more Colliders to the Colliders list property. To increase the number of Colliders in the list, click the Add (+) button beneath the list of Colliders. To remove a Collider from the list, select the Collider and click the Remove (-) button. If you have not yet assigned a Collider to an index of the list, you can use the smaller Add (+) button, to the right of the empty entry, to create and assign a new Collider. This creates a new GameObject as a child of the Particle System and attaches a Sphere Collider
to it, then assigns the Collider to the empty entry.

After you add the Colliders, you can then specify what a particle does when it meets the criteria for passing a particular trigger event type. There are four event types that describe how a particle can interact with a Collider
https://docs.unity3d.com/Manual/PartSysTriggersModule.html

[fervent kernel]

Don't really get it, so I need to take every collider I want the particle system to collide with and drag it into the array?

[leaden ice]

yes

It can only interact with colliders in that list

Can I ask what you are actually trying to do with this stuff?

[jade vault]

Hi, anyone familiar with terrain generation using Perlin Noise on a tilemap?

[thin kernel]

Is there a way to disable touch input (but keep the mouse input) from windows touch screen build?

I found only Input.simulateMouseWithTouches function in google, but that doesn't seem to do anything.

[fervent kernel]

I have an ice attack coming up from the ground, from underneath the enemy.
The gameobject of the ice attack includes multiple children with all of them having a particle system attached to them. Each of the children is a different part of the overall particle system which make up the ice attack.
I want the child which has the particle system of the actual ice spikes, to collide with the enemy and fire an event once it does, I don't want the enemy to stop its movement when it collides with the ice. I want it to keep moving through the ice.
The enemy has a non trigger collider attached to it.

[fervent kernel]

I don't want the ice to physically interact with the enemy, as I want to simply trigger an event when they do collide

[leaden ice]

I would just have the attack use some physics queries like Physics.OverlapSphere/Box/Capsule etc.

the particle system collision stuff is sketchy at best

[knotty sun]

or you want your children to have trigger colliders if the enemy has a rigidbody

[fervent kernel]

I thought about it but the attack also goes forward as the spikes grow

[fervent kernel]

Yeah the enemy also has a rigid body

[knotty sun]

then triggers on the children should do the job

[leaden ice]

seems like something that can be done pretty easily with a bunch of CapsuleCasts or OverlapCapsules

[fervent kernel]

I thought about having an OnParticleCollider and just disabling the collider once it collides with the enemy, sort of a workaround

it looks something like this
https://www.youtube.com/watch?v=xd-hhJbyC7I&t=1s

[jade vault]

Hey, is anyone familiar with perlin noise terrain generation on a 2D tilemap?

I am just wanting to set transition tiles between two biomes, I'm not looking for code but just general ideas on how to accomplish this. Is tileset rules a good idea?

[dusk apex]

If both objects need colliders but you aren't wanting physics interaction between them, perhaps you can just set them to not interact with each other?
https://docs.unity3d.com/Manual/LayerBasedCollision.html

[fervent kernel]

damn, I haven't thought of that

[heady iris]

Using particle colliders to produce actual gameplay effects sounds a bit flaky to me.

[fervent kernel]

wait but if I set them to not interact through layers... wouldn't that mean I won't be able to discern if they collided at all?

[fervent kernel]

How would you make it so for example an upwards ice attack like i've linked here would just hurt the enemy (who has a non-trigger collider).
By hurt I mean lower his health points variable

[heady iris]

use a trigger collider or do a physics query

[fervent kernel]

how would you use the trigger collider?

The ice attack comes froward and not all at once from underground

[heady iris]

then i'd use several trigger colliders, or I would use OnTriggerStay and ignore enemies that aren't in range yet

[knotty sun]

as you describe it, put a trigger on each child

[fervent kernel]

Problem is the ice spikes is one child and consists of all the spikes of the particle system.
I don't have access to each and every spike individually

[knotty sun]

'The gameobject of the ice attack includes multiple children with all of them having a particle system attached to them. Each of the children is a different part of the overall particle system which make up the ice attack' ?

[fervent kernel]

Yeah, the ice attack particles consist of snow, sparks, ice spikes, wind, trails

All of them are different children

[knotty sun]

and you want to trigger them at different times of the attack?

[fervent kernel]

Yes as they come out at different times

The attack comes out forward and upwards

[knotty sun]

so add a trigger to each child so you know when that particular type of effect has hit the enemy

[fervent kernel]

I don't want to add to each child. I want to add it only to the ice spikes. But then I would have to play with the settings to get every trigger collider to match each of the spike's speed

[knotty sun]

The art of development is not doing what we want but what the game requires

[fervent kernel]

this would be a mess of a script not a piece of art 😂

[knotty sun]

that would depend on you

[heady iris]

you will probably create other attacks that move in a "wave" like that

figure out how to reliably detect hits once, then use that logic many times

[green ice]

In the start method i change the position of the object and it is the only time i change it

it is like it returns in the position of when the session starts
