Sounds like you want the clockwise angle. In which case you just need to reverse the order of the parameters

[tawny grove]

isnt counter clockwise the normal way?

let me reverse it and check

i think its because

[wintry quarry]

what do you get when you reverse

Vector2.SignedAngle(Vector2.right, directionToGhost)

[tawny grove]

vector2.angle is on a 180* scale instead of a 360*

let me check

[wintry quarry]

well it returns a value between -180 and +180

never anything beyond that.

So if you want to translate that [-180, 180) to [0, 360) you need to do like:

Vector2.SignedAngle(Vector2.right, directionToGhost);
if (angle < 0) angle += 360;```

[tawny grove]

this seems to sometimes(?) work, im testing with multiple enemies and it seems like if they come from the front it stops working

[wintry quarry]

stops working how

like what happens

also what is the end goal of all this?

What are you doing with this angle value?

[tawny grove]

as in it gets the wrong angle

[wintry quarry]

Can you show the code, a screenshot of the scene, and what angle it's returning?

And what angle you expect it to return?

[tawny grove]

circling the player, normally id use an easier method but i have weird movement/velocity system that makes it a little more complicated

sure

[wintry quarry]

How does this have you circle the player?

[tawny grove]

by increasing the angle every frame

im trying to grab the initial angle

[wintry quarry]

so wouldn't you be driving the angle from a variable here instead of calculating it from positions?

I see

[tawny grove]

the first image is getting the initial angle when the enemy enters range, the second is using it (and increasing it) to set position

[wintry quarry]

Are you intentionally doing =- there?

[tawny grove]

for testing purposes bc it wasent working without it before, yes

[wintry quarry]

that's the same as just =- x is just the same as = -x

there isn't really a thing of =-

[tawny grove]

oh you meant that

mistype

btw when i was saying the actual angles, it was from the print, not after it decides its position in the second image

[steel smelt]

Is current angle converted from deg to rad anywhere?
Also sin(0) == 0 whereas cos(0) == 1. At 0 degrees, it should be (1, 0) and right now you have (0, 1) because you swapped cos and sin

[wintry quarry]

Also you could just do this:

Vector2 initialOffset;
float rotationAngle = 0;

void StartFollowing() {
  rotationAngle = 0;
  initialOffset = transform.position - player.position;
  following = true;
}

void Update() {
  if (following) {
    rotationAngle += Time.deltaTime * rotationSpeed;
    Vector2 newOffset = Quaternion.Euler(0, 0, rotationAngle) * initialOffset;
    transform.position = player.position + newOffset;
  }
}

[tawny grove]

does it need to be converted into rad? isnt sin 45* persay like sqr2/2, just as sin(1/4)r?

[wintry quarry]

Sin accepts radians

(and cos)

so yeah if you want to feed degrees in you need to convert

[tawny grove]

oh

[wintry quarry]

also yeah your sin/cos are reversed for x/y as foo said

And you can avoid all that by just rotating the initial offset vector with a quaternion like in my example

[ripe matrix]

Hello, is there a way to make a conditional public variable? Like if a certain condition is met, then the variable shows up on the unity editor.

[wintry quarry]

Not without a custom editor or a plugin

[wintry quarry]

Here's a popular free plugin that does it: https://dbrizov.github.io/na-docs/attributes/meta_attributes/show_hide_if.html

[ripe matrix]

Will check it out, thank you!

        return request.error;
    }```

Why does this code work in the windows build, but not in the web build?

[tawny grove]

oh sick that worked. could you explain what Quaternion.Euler does?

[wintry quarry]

it creates a quaternion that represents the rotation given by the set of euler angles you pass in

in this case "A counterclockwise rotation on the z axis by rotationAngle degrees"

[tawny grove]

i have not reached that in math class 😭 ill look into it. tysm

[fleet venture]

this works fine in the windows build and in the editor

[mental prawn]

how do I move the canva? it is way too huge for my game sizes and I can't seem to be able to move it

[rich adder]

because its meant to size with your screen , you don't move it

also not a code q

[mental prawn]

a what?

[wintry quarry]

The way the canvas is drawn in scene view has nothing to do with "size" of it. It is always the same size as your game resolution.

[mental prawn]

but look where the camera is

[wintry quarry]

(not a code question)

[wintry quarry]

yes the UI is not drawn on the camera

you're using a screen space overlay canvas

it is drawn directly on the screen

with 1 unit (1 meter) = 1 pixel in the scene view

that's why it looks huge

[mental prawn]

so that means the camera is irelevant?

[wintry quarry]

this is normal and fine

[wintry quarry]

In regards to this canvas, the camera is irrelevant yes.

[mental prawn]

aaaaaaaaaaaaaaaa

that makes sense

I was thinking about having a large background and when going through the buttons the camera move as well

[fleet venture]

Is it possible to run a built app in debug mode?

probably not right?

[rocky canyon]

theres a Developmental Build

[fleet venture]

ok ill try that

[rich adder]

you realize this is a code channel?

look in #📲┃ui-ux

check the pins

[mental prawn]

sorry, where could I send

a, got it

going to delete it

[hallow sun]

I think calling one IEnumerator (yielded every 3 seconds for checks) is causing another one to stagger (yielded every 0.1 seconds for animating) is this possible?

[wintry quarry]

Coroutines will not affect other coroutines generally unless one is yielding on another. What weirdness are you seeing?

what do you mean by "stagger" exactly

[scarlet skiff]

can someone help me figure out why this always returns false, even when a debug shows that player transform is not null and draw ray shows the ray piercing the player so it definitely reached the player?

full code: https://paste.ofcode.org/wYCpCkSAKmEGnsDSBzGp89

[hallow sun]

The staggering coroutine controls a "blinking light" image by adding/substracting from the Lerp value on its shader, the stagger is that it stops for a bit every 3 seconds or so, thats why i think the other coroutine might be responsible.

[wintry quarry]

how long is "a bit"? if you're just using a loop with WaitForSeconds(3) in it, you're ot going to achieve a perfect 3 second consistent timer with a coroutine

[hallow sun]

The animation stops for about half a second, pretty noticable

[wintry quarry]

your raycast is using max distance of 1

you need to put detectionRadius in the max distance param, not multiply it by the direction

Assuming detection radius is larger than 1, that could be the problem

[wintry quarry]

Maybe show some code

[scarlet skiff]

changed it to this, and detection radius always stays at 8, but stil lreturns false

unless i misunderstood smething

[wintry quarry]

that is correct as per what I was mentioning

what object are you expecting the raycast to hit?

Can you show the inspector for that object?

[scarlet skiff]

target of the raycast

omg wait

[wintry quarry]

Also have you actually checked if and what your cast is hitting?

if (hit.collider != null) {
  Debug.Log($"We hit {hit.collider.name} which is on layer {LayerMask.LayerToName(hit.collider.gameObject.layer)}");
}
else {
  Debug.Log("Raycast hit nothing");
}```

[scarlet skiff]

could the raycast be hitting the thing it is being emitted from?

[wintry quarry]

yes

[scarlet skiff]

ah

[wintry quarry]

so I recommend this

[scarlet skiff]

yea i had forgotten to assing the enemy to the enemies layer

so it hit itself

[fleet venture]

any ideas why this doesnt work in the web build?

[timber tide]

Is this multi-threaded?

if so then it wont work

[wintry quarry]

what is failing specifically?

And yeah if you're e.g. starting this with Task.Run, that's an issue.

[fleet venture]

I am awaiting it

it just waits infinetly i think

its a bit hard to know whats going wrong because it works in the editor

and it also works in app build

just not in web build

[fleet venture]

im not sure

i just await this

so i doubt it

i dont explicitly start a new thread for it

but isnt async always like multi threaded

[timber tide]

not necessarily, no

[fleet venture]

ye tbh i guess its not rly cuz i await in the same line as i call

[wintry quarry]

Have you checked the javascript console for errors?

[timber tide]

Usually I just use coroutines for webgl and if I need to await I'd just poll the token till it's done

[fleet venture]

let me take a look

i didnt htink about that

[fleet venture]

that sounds rly confusing

[timber tide]

Unity also has the awaitable class too which is actually good for it

[fleet venture]

uh oh

idk what that means

i hadnt thought about checking the javascript console

[fleet venture]

i have NO clue what this means

im not rly that good with web dev

[rich adder]

are you trying to access resource on a different location / domain

[fleet venture]

well ye from my api

its azure

but its just an api call

[rich adder]

you have to add it to the headers

[fleet venture]

what do i add

you mean to the headers of the request?

[rich adder]

yes

[fleet venture]

and what do i add?

[rich adder]

I think you have to do it from azure actually, Its been a bit since I touched unity webgl / js

[grand badger]

just the standard CORS stuff on your backend

what is your backend?

[fleet venture]

i have no idea what CORS even is

its an azure thing

but im using free student stuff

[rich adder]

https://docs.unity3d.com/6000.2/Documentation/Manual/webgl-networking.html

[fleet venture]

so i dont have full features

[grand badger]

wait the error comes directly from Azure?

[fleet venture]

nah

[grand snow]

Not sure if unity make it easy, but if the page is using CORS rules, you need to add rules too to allow your traffic to endpoints

[grand badger]

CORS is this btw: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

[fleet venture]

i get this

[grand snow]

may just mean you need to add these to the page hosting your content:
https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

Ha

[rich adder]

did you look at the link I sent

[fleet venture]

not yet

it says to add the headers but idk how to add the

[grand badger]

the headers are to be added server-side

if you're getting the error from a server you don't own, use a different server

[fleet venture]

i do own it

i Uploaded code to azure

[rich adder]

azure has many services

[fleet venture]

its an API

its a database with an api

[rich adder]

but are you using a Web App ?

[fleet venture]

im trying to send requests to the api

[rich adder]

or. Serverless functions

[grand badger]

Yes. What is your backend?

is it python? is it C#? php maybe

[fleet venture]

app service

these 4 do it

[grand badger]

aaand I'm out xD

[fleet venture]

its C#

backend is asp.net

core

[grand badger]

https://learn.microsoft.com/en-us/aspnet/core/security/cors?view=aspnetcore-9.0

[rich adder]

uhh weird. I cant react with "This"

but yeah the link ^

[grand badger]

just use * as origin

[fleet venture]

ah great

ill try it

[grand badger]

this is the ASP.NET Core equivalent: policy.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader();

but if you WebGL build is on a specific site, it's recommended you use that specific site as origin instead

[fleet venture]

what if its localhost?

then i have to use star right?

cuz ip changes

[grand badger]

no just http://localhost. But if you're not sure use AllowAnyOrigin()

[fleet venture]

the api already filters on ip

so i think allowanyorigin would be fine

[grand badger]

ok

[fleet venture]

weird i still get the error

[grand badger]

show code?

[fleet venture]

builder.Services.AddCors(options =>
{
    options.AddPolicy(name: "_all",
        policy  =>
        {
            policy.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader();
        });
});```

[grand badger]

you need to app.UseCors() after that of course

[fleet venture]

app.UseCors("_all");

i have that

[grand badger]

yes

[fleet venture]

im not sure maybe it hadnt updated yet

let me test again

OH DAMN IT WORKS NOW

TY

[grand badger]

np

yeah recommended to read a bit about CORS from mozilla website to understand what it is

[fleet venture]

ye

uh oh is itch.io down?

[grand badger]

converse with ChatGPT or browse stackoverflow or reddit if you need clarifications

but know that CORS is super important on web APIs 😛

[fleet venture]

smh my school didnt tell us anything about it

[grand badger]

it even touches security -- like when you don't want your app to be embedded on another random webpage

[mortal ginkgo]

i'm new to unity where should i start to learn?
i LOVE 2d but none of unity learn's pathways were what i'm looking for

[bronze jewel]

I don't even use unity I'm just here :3

[cosmic dagger]

If you don't want to look at any Unity learn tuts, then search for tutorials online, like YouTube, etc . . .

[mortal ginkgo]

okie

[eternal needle]

if you're already good with coding and know how to debug/experiment properly, then you can use tutorials to find out what exists relevant to what you need. Try implementing a feature, google to see what other people use to solve such problem, find out new components exist, experiment with it. That's pretty much what I did. Lots of tutorials by themselves are really bad if you follow step by step

[mortal ginkgo]

i am completely new

[eternal needle]

then realistically you should be using the unity learn site, or at least start with c# basics outside of unity to give yourself a headstart. Being confused with unity AND c# at the same time is not fun

[mortal ginkgo]

i've done a little bit and managing unity isn't that much for me
it's just C# and basics

[scarlet skiff]

why does it not consider player as visible?? the player is more than close enough

   bool IsPlayerVisible()
   {
       if (playerTransform == null) return false;

       Vector2 directionToPlayer = (playerTransform.position - transform.position).normalized;
       float distanceToPlayer = Vector2.Distance(transform.position, playerTransform.position);

       RaycastHit2D hit = Physics2D.Raycast(transform.position, directionToPlayer, detectionRadius, ~LayerMask.GetMask("enemies"));
       Debug.DrawRay(transform.position, directionToPlayer * detectionRadius, Color.red, 1);

       return hit.collider != null && hit.collider.gameObject.layer == LayerMask.NameToLayer("player");
   }

Full code: https://paste.ofcode.org/LpXP7n3Dp6gVWKbWPVE2Sv

[grand badger]

maybe playerTransform is null?

[scarlet skiff]

nope i checked

[grand badger]

also, why not just check if (hit.collider.transform == playerTransform)?

[scarlet skiff]

that probably is better indeed

[grand badger]

Can you send pic of the player's hierarchy (+ inspector)?

[velvet holly]

Also your enemy does have the "enemies" layer on them right?

[grand badger]

you'd be better off doing Physics2D.OverlapBox(pTr.pos, Vector2.one * 5, 0, ~GetLayerMask("Enemies))

[scarlet skiff]

yes its not hitting itself

[grand badger]

player layer is not visible here but I assume it's correct

[grand badger]

anyway go ahead and try with this, just in case

then switch to OverlapBox anyway 😛

[scarlet skiff]

i dont want it to detect the player when they are not actually visible, like if a platform is clocking the view

which is why i use raycast

[scarlet skiff]

yes

[grand badger]

yes but Physics2D ignores Z AND sortingOrder, so your raycast is XY only

oh XY only is correct, I see.

[scarlet skiff]

does not already ignore z? cuz its physics 2d and the vector is vector2, and i give ray cast the righ direciton to the player anyways

[grand badger]

and you've checked that Debug.DrawRay(transform.position, directionToPlayer * detectionRadius, Color.red, 1); draws the correct line?

[scarlet skiff]

yes

[grand badger]

try Debug.Log(hit.collider) then.. something is blocking the ray

[scarlet skiff]

still false despite raycats clearly seeing the player

[grand badger]

^ something's blocking the ray for sure

[scarlet skiff]

ah u were right

omg

its the damn stick

it has an invisible hitbox, so when u pick it up and it becoems child of the player, u can actrive the hitbox

as an attack

[grand badger]

yeah imo be more explicit with your conditions

[scarlet skiff]

i have no clue how to create a good system with tags and layers

like an effecient system

[grand badger]

for example, you can make the raycast not ignore ALL enemies, but only the SPECIFIC enemy that casts it

[scarlet skiff]

with all the stuff going on

[grand badger]

and then check if hit.collider.GetComponentInParent<Player>() != null

[scarlet skiff]

i think ineed a package that allows a gameOvject to have multiple tags

[grand badger]

or something more optimized depending on your computational needs...

no no... simpler is better

[scarlet skiff]

i feel like that is simpler

[grand badger]

you can traverse up the hierarchy and check for the player

[scarlet skiff]

for example i could have a tree decoraiton that is a hiding place

then i have ground tag

[grand badger]

if you think a whole package to maintain will be simpler than 1-3 lines of code then sure 😛

[scarlet skiff]

wait i dont need multiple tags for that

ugh im lost

[scarlet skiff]

i want enemies to see through each other

i dont know how ill make the raycast only hit hiding decoration and ground

i wanna avoid making new layers as much as possible

[grand badger]

you don't have to only hit specific stuff. The stick is child of the player, right?

[scarlet skiff]

not when its a ground item, no

which was the case here

[grand badger]

if (hit.collider == null) { return false; }

var tr = hit.collider.transform;
while (tr != null) {
    if (tr == playerTransform) { return true; }
    tr = tr.parent;
}
return false;

ah.

[scarlet skiff]

ye that makes it a lil tougher

[grand badger]

maybe fix its collider 😛

the bigger collider should only be a trigger at best -- which isn't intercepted at raycasts by default afaik

[scarlet skiff]

it is a trigger.. its still bein intercepted :/

[grand badger]

ah well there's an overload that uses ContactFilter2D

you can disable hitting triggers if you use that

https://docs.unity3d.com/ScriptReference/ContactFilter2D.html

but by default it should've been disabled.. not sure what's going on there

[scarlet skiff]

not to be difficult but, is... there someother way? i want to add bushes with trig colliders in the future to block out the visibility for enemies

[scarlet skiff]

i use an older unity version maybe thats why

[grand badger]

you can use RaycastAll and iterate through the things manually

if there's a ground or decoration, halt, otherwise, continue until you find the player or end of list

[scarlet skiff]

that gets everything that the ray cast hits?

[grand badger]

yes, piercing

[scarlet skiff]

so a list colliders

[grand badger]

yeah https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Physics2D.RaycastAll.html

[scarlet skiff]

and if the index of the ground is lower than the index of the player, that means the ground came first, meaning then player should be invisible. and if bush index is lower than player, then player is inside the bush and player should also then be invisible

[grand badger]

yes I think so

[prime cobalt]

I'm trying to make it so that the camera is attached to the body model's head when kicking when normally it isn't directly connected but it always seems to just base the length off the previous animation. There has to be a better way to do this right?

[wintry quarry]

Could you use an animation event here instead?

Or a state machine behavior

[prime cobalt]

I'll look up what that is

[scarlet skiff]

bool IsPlayerVisible()
{
    if (playerTransform == null) return false;

    Vector2 directionToPlayer = (playerTransform.position - transform.position).normalized;
    float distanceToPlayer = Vector2.Distance(transform.position, playerTransform.position);

    RaycastHit2D[] hits = Physics2D.RaycastAll(transform.position, directionToPlayer, distanceToPlayer);
    Debug.DrawRay(transform.position, directionToPlayer * detectionRadius, Color.red, 1);

    bool playerHit = false;
    int? playerIndex = null;
    List<int> obstacleIndex = new List<int>();

    for (int i = 0; i < hits.Length; i++)
    {
        if (hits[i].collider.gameObject.layer == LayerMask.NameToLayer("Player"))
        {
            playerIndex = i;
        }
        else if (hits[i].collider.gameObject.layer == LayerMask.NameToLayer("Ground") ||
                 hits[i].collider.CompareTag("hiding spot"))
        {
            obstacleIndex.Add(i);
        }
    }

    if (playerIndex != null)
    {
        if (obstacleIndex.Count == 0)
        {
            return true;
        }
        for (int i = 0; i < hits.Length; i++)
        {
            if (hits[i].collider.gameObject.layer == LayerMask.NameToLayer("Ground")) return false;
            if (hits[i].collider.CompareTag("hiding spot"))
            {
                return false;
            }
            if (hits[i].collider.gameObject.layer == LayerMask.NameToLayer("Player")) return true;
        }
    }

    return false; // Otherwise, player is visible
}

this is what i made, obv some stuff can be written more effeciently such as no need for obsticleIndex list, i could simply have a bool value doesIncludeObsticle and settings it to true instead of the line obstacleIndex.Add(i); but i kept it this way because i might do a change later because rn, if u stand between the ground and a bunch and an array hits at the right angle that it catches both ground and bush it would count player as invisible even if the player is not

inside the bush

which, considering i have flying enmeis with code that tells them to avoid the ground making such an angle hard to come by, i still dont like that im not doing this correctly, its hard to find an elegant solution for this.

at first i thought to have two trigger colliders for the bush, one surrounding hte bush and one actually inside the bush, and only if yo uare touching the one inside, without touching the one outside, then do you count as inside but then just connecting everythign together would be very tricky and akward

any... suggestion to this? lol

unless maybe there is a way to see how much of a collider %-wise is inside another collider

[grand snow]

well you can check how close to the center of the collider the player is and infer something from that

you can presume if they are very close or at the center then they are "full inside"

[wintry quarry]

You could have a few empty GameObjects placed on the outer extremities of the enemy model, and while you're inside the trigger you can check with ClosestPoint if all of the empty objects are contained in the collider. If they are, you are fully inside the collider

you can tune this to be more or less accurate using more or fewer points as needed

[hardy ibex]

Im new to game dev (started yesterday) how would i make a button in 2d which is pressed if the player stands on it?

[wicked pulsar]

If you're looking for a very high-level idea for how to start, you could try getting your player to enter a trigger collider (that is a collider2d with IsTrigger = true) and get that to do something. There are a lot of ways that this could be achieved depending on how much physics math you want to get into, but I think that this might be a good starting quest.

Congrats for taking an interest, and welcome to the tribe!

[hardy ibex]

Thanks! i will try to do that!

[wicked pulsar]

If you're looking for some things to search for to start with, take a look at understanding what OnTriggerEnter2D() does.

Also, look in your project settings and make sure that you understand that the 2D physics matrix exists. It looks like a triangular grid of checkmarks. That will be important...

[hardy ibex]

k. One other question i have is if i have an object that will be duplicated and used in many different areas which has some children objects, is there a way to adjust the children of one of them and adjust all of the others if that makes sense?

[wintry quarry]

use prefabs

[hardy ibex]

ok ill try that. thanks

[hardy ibex]

that worked! thanks

[wicked pulsar]

I'm impressed that you put that together so quickly! Here's a slightly more advanced way to do that:

Recognize a collision with your switch, look inside the collision and if some force is above some activation threshold, trigger an effect.
Look up OnCollisionEnter2D().

[scarlet skiff]

why does it not detect an intersect despite me being fully submerged in the trigger collider??

code: https://paste.ofcode.org/JYRxML5axyzMKJbauzpaYD

[wicked pulsar]

Looks neat. First of all, do you ever get "here" to print?

[scarlet skiff]

nope

thats the issue i cant figure out

something about using bounds to check if they intersect is wrong

[wicked pulsar]

Is it possible that there's an issue with the setup before you call this method?

I wish that instead of #💻┃code-beginner, there was a chat for #code-stupid-shit-that-drives-us-nuts

[scarlet skiff]

nope, i 100% give it correct parameters, the correct colliders, trigger beings the player, target being what the player hides in

[scarlet skiff]

real

idk, its late, maybe thats why, but i cannot let this go

[wicked pulsar]

I think I would have to see the test setup. That looks pretty solid.

[scarlet skiff]

i mean there are a lot of things, anything in specifc i could provide?

[wicked pulsar]

I don't really know what you're doing to test this. CalculateOverlapPercentage is a static function. I think I would need to see some kind of Unity-driven code, or a case where you're instantiating two objects at fixed positions and then trying this method, etc.

You could try changing the parameters to accept Rect directly instead of Collider2D, then just write some tests.

[scarlet skiff]

well, i call it here: https://paste.ofcode.org/Zd25qCaYtS56JfRJSDdCfZ

[wicked pulsar]

If I were you, I would rewrite this to accept Rect instead of Collider2D and just write a test case.

That way, you have only math and don't necessarily need to worry about what is going on in some physicalized game world.

By a test, I mean:

Rect A = new Rect(x,y,width,height);
Rect B = new Rect(x,y,width,height);

CalculateOverlapPercentage(A, B);

It's all boxes anyway. You can control the values of A and B. Once it works, you can substitude the rects for colliders (and their bounds).

@scarlet skiff I just asked ChatGPT to make a more easily-tested version of your code:

public static class PhysicsCalculations
{
    public static float CalculateOverlapPercentage(Rect trigger, Rect target)
    {
        Debug.Log($"Trigger Rect: Min({trigger.min}), Max({trigger.max})");
        Debug.Log($"Target Rect: Min({target.min}), Max({target.max})");

        if (!trigger.Overlaps(target)) return 0f; // No overlap
        Debug.Log("here");

        float xOverlap = Mathf.Max(0, Mathf.Min(trigger.max.x, target.max.x) - Mathf.Max(trigger.min.x, target.min.x));
        float yOverlap = Mathf.Max(0, Mathf.Min(trigger.max.y, target.max.y) - Mathf.Max(trigger.min.y, target.min.y));
        float overlapArea = xOverlap * yOverlap;

        float triggerArea = trigger.width * trigger.height;

        return (overlapArea / triggerArea) * 100f; // Percentage of overlap
    }
}```

Try to make sure it works with Rects.  If it does, then the problem is with how you set up your tests.

Create an Awake() method on a MonoBehaviour with constant Rects and feed them in. Make sure that works before testing against actual colliders. It will take some steps out of your search.

[hardy ibex]

this is what ive made so far. the idea is a platformer where you can change your weight

[wicked pulsar]

Awesome! Would I be right to assume that you are new to Unity, but not to C#?

[hardy ibex]

ive done a little terraria modding which is csharp but other than that not much.

but yes i started unity yesterday

[wicked pulsar]

Alright, well it seems like you're moving fast.

Did you research other game engines before choosing Unity?

[hardy ibex]

i did and i though unity looked like it would suit my needs best

[wicked pulsar]

Between the big three (Unreal, Unity, Godot), I would say that Unity is the most flexible. It is a graveyard of abandoned features that exist half-finished, but is the easiest to mold to whatever it is that you want it to do so long as you are competent as a programmer and are willing to put up with learning its history a bit.

[spice locust]

does anyone know how to fix this im doing a collaboration and my friend owns the organization, whenever i try to check in this pops up

[wicked pulsar]

Godot is less refined, but catching up quickly, but holds on to gating its development behind support for simplified custom scripting. Unreal is exactly one thing which you need to mold deliberately into something else if you aren't making a first person shooter.

[hardy ibex]

unrelated but how would i add a glow outline to an object?

[wicked pulsar]

In short, I don't actually know who uses Unity Version Control over Git LFS. Sorry. 😦

[spice locust]

its ok thanks though

[wicked pulsar]

I'm not sure where to ask either. Maybe ping some channels; I think this is a question where we could all benefit from knowing how to direct it.

[spice locust]

ok thanks

im gonna try looking for people that know how

[eternal needle]

Did you Google the error? I don't use uvc either but there seems to be some relevant results when I search it up.

[wicked pulsar]

Are you on linux?

[spice locust]

thats what im doing rn

[spice locust]

im not sure

[wicked pulsar]

UGH. What?

[eternal needle]

I dont think I've seen many people actually give answers to uvc errors here 😅 you should 100% use git

[spice locust]

wdym by linux

sorry im kinda new to unity

[eternal needle]

Likely through a shader, but google to find tutorials which do what you need. Either way this isnt really a coding question or solved through code

[wicked pulsar]

Sorry, you caught me by surprise with that question. Do you know what Microsoft Windows is? @spice locust

[eternal needle]

Linux, the operating system

[spice locust]

yeah

i have that

[wicked pulsar]

Is that what is running on the computer that you're using right now?

[spice locust]

i think i have linux

[hardy ibex]

ok thanks

[eternal needle]

I feel like anyone that uses linux would know they use linux. Maybe just give a screenshot of your desktop

[hardy ibex]

well in your taskbar on the bottom of your screen is there a logo that looks like a window made up of 4 squares

[eternal needle]

We can see from the bottom bar if theres like the windows search or whatever linux has

[spice locust]

yeah

[hardy ibex]

then youre using windows

[west radish]

It's going to be windows

[spice locust]

ok

[eternal needle]

I'm gonna guess that you arent far along in your project. I would highly recommend just swapping to git

[spice locust]

whats git?

im kinda new to unity

[wicked pulsar]

@spice locust Does your desktop look anything close to this:

[spice locust]

no

my bottom bar is different

but the top is similiar

[wicked pulsar]

This?

[west radish]

We've already established they're using windows

[eternal needle]

The future is now old man 😅

[spice locust]

yeah

[wicked pulsar]

Okay. That's windows, and not Linux.

[spice locust]

oh ok

thx

[eternal needle]

It is version control. If you're new to coding also, you might be in a rough time. I would highly suggest starting by learning c# outside of unity.
Then with git, experiment on it with text files, things you don't care about potentially messing up.

[wicked pulsar]

@spice locust Okay. So regarding "ci" on "/", I would leave the issue to someone who might have some idea what "/" means with respect to whatever mounted directory that is referring to.

[scarlet skiff]

something like this?

[hardy ibex]

would it be easy to emit some particles when i interact with my interactable?

[spice locust]

ok thanks im also doing the version control with a dev thats been deving for a year+

[spice locust]

ok

[eternal needle]

It's one function call, so yes

[spice locust]

ive never used version control

so yeah

[hardy ibex]

k how qould i do that exactly

[wicked pulsar]

@spice locust It's genuinely hard to talk about these things if you aren't entirely sure about file systems. If it's a common error that you're seeing, those of us who don't know about Unity's built-in version control can't ask you questions without probably going a bit over your head, which wouldn't help anybody. Perhaps it is best that your friend figure it out for you because we can't really help if you don't know basics of version control.

[eternal needle]

Ok it might be hard to convince them to swap, especially if it's coming from someone who hasnt coded before.

[wicked pulsar]

Not to sound condescending, but understanding what operating systems are out there is level 0.

[spice locust]

yeah

they are the owner of the orginization so hes the owner of the project

so he would have to give me permission i think

he tried too

but i looked on chatgpt and i think its gonna help

[wicked pulsar]

Honestly, let them figure it out or hire someone if he doesn't know. It's 1000% harder for us to guess at what your situation is.

[eternal needle]

From what I saw online, it does just seem like a permission issue.

[spice locust]

ok thanks sm

[eternal needle]

Is there a question with this? If you're showing the warning, it's quite clear in what its saying

That you cannot new a monobehaviour

[wicked pulsar]

One of the great things about game development is that it encourages people to pick up technical skills, but nobody is psychic here. If you're behind or unfamiliar with what you're dealing with, we cannot place ourselves in your shoes and see things as you do.

[spice locust]

yeah ik

it was worth a shot though

[polar acorn]

Play the particle system wherever it is you handle your interaction

[wicked pulsar]

That's a good thing, though!

[spice locust]

yeah!

[polar acorn]

First warning is important you should read it

[wicked pulsar]

Yeah. You've taken the moving parts out of the problem. Now you can try to solve the issue using rects that you could technically write down on paper. A good starting point would be that (rect, rect) should return 100 if it works.

[wicked pulsar]

Groannnnn

Get off my lawn.

@spice locust If you're looking for a source of truth, whoever is asking you to use version control should be able to explain to you what they expect. It shouldn't be your job if you're coming into a project to figure out how to help them help you as the first thing that you do.

[shy ruin]

I know this might be complicated but how do you print something to the console I've forgotten.

[sour fulcrum]

Debug.Log

[shy ruin]

Thanks

[sour fulcrum]

If I instantiate a prefab will a raycast right after that be aware of it’s colliders? And if not can i call for a early physics update or do I need to wait for the collider to initialise

[wicked pulsar]

This question is basically asking about the execution order of Unity Events (Update, FixedUpdate, etc.)

[scarlet skiff]

it did return 100

[wicked pulsar]

Okay, are you familiar with unit tests?

[scarlet skiff]

uhh not really 😅

[sour fulcrum]

yes

[wicked pulsar]

FixedUpdate comes immediately after any physics calculations, but Update is desynchronized from that. Whether this will happen depends on exactly when you're instantiating something. If it's on FixedUpdate, it will be on the next frame. If it's Update.... it depends I guess.

[sour fulcrum]

I know but I don't know how collider initialization plays into that

[wicked pulsar]

Collider interactions trigger on the physics step, right before FixedUpdate. 100% everytime, all the time.

[wicked pulsar]

So I actually would really recommend that you learn that now, because this is actually exactly the kind of problem that you can systemically eliminate in your project.

[grand badger]

yes it will there's a thing called Physics.SyncTransforms() that syncs ALL transforms on the physics engine. There's also a thing called Physics.autoSyncTransforms that automatically syncs each specific transform that changes. That is on by default.

[scarlet skiff]

hmm i see looks like ill have to look up a tut. since this doesnt seem like something i can solve soon though ill have to push it til tmr

anything else i should keep in mind when i get the chance to check it out?

[grand badger]

geez Unity is trying so hard to push Unity 6 lol.. All docs links contain 6000.0 now

[wicked pulsar]

I'm in a pretty strange crash state with my current project, else I'd share my stuff with you. Actually, I can try.

Unity has built-in support for NUnit if you want to start reading on that. @scarlet skiff I'll ping you if I can find a moment to help if you'd like.

[grand badger]

please keep in mind this is #💻┃code-beginner :p

[scarlet skiff]

would love to, but it seems like something a little extensive, so ill have to circle back to it tomorrow, its 4:17 am where i am, so my ability to think creativly is quite dampned this late

[sour fulcrum]

not trying to start a whole thing here but this is code-beginner and your feeding a stranger chatgpt code and recomending unit testing

[scarlet skiff]

so... on the bright side if my errors require advanced solutions then im no longer a beginner?

lols, welp we were just wrapping up

[sour fulcrum]

I don't know if your errors require advanced solutions

collision intersection is abit more than most beginner stuff posted here but not crazy crazy

[scarlet skiff]

hmm maybe not, it does seem like just simple values dont wanna act right

[wicked pulsar]

@scarlet skiff Here is one of my tests files: https://pastebin.com/eS3HNUNK I can't show you how this looks inside of Unity, but you might be able to get an idea what those methods are for. The Assert directives basically work like return bool statements if they do or don't achieve the thing that they set out to do.

[scarlet skiff]

testing with rect showed it worked... but with bounds it dont

[sour fulcrum]

Out of curiosity what do you need the overlap percentage for?

[wicked pulsar]

@scarlet skiff Here is how this looks in the tests inspector. Basically, you make methods that should always return true and they act like canaries in a coal mine... if ever you do something that would cause these test methods to fail, you get a loud error before the problem gets lost in your spaghetti.

[scarlet skiff]

check how much of the player is inside a bush, if enough of the player is inside a bush only then is the player invisible, i cant get a correct reading on if the player is sible or not with just ray casts (cuz at first i was like, well, if the raycat hits bush first, then that means the player is inside and hidden) because what if it does hit bush first, but goes through it and catches player, it might read that as player is insibile while they are not

[wicked pulsar]

What I would do with your percentage overlap method is create tests where you work out the math that if two rects overlap each other half-way in the X and Y coordinates, you get 25% coverage. If one is on the positive X side of a cartesian 2D system and the other is on the negative X side, you get 0%, and if the same rect is passed in for A and B you get 100%. Make a test that returns true in all cases and leave that forever in your project so that it will cry foul if it ever fails.

[sour fulcrum]

If the bush object is centered correctly can't you just distance check?

[wicked pulsar]

Then, start passing it colliders when the math works...

[scarlet skiff]

and the reason i use a raycastall is cuz i need to know the order of what ray htis first and i need the ray to go through certain things that i cant avoid with just configuring layers

[grand badger]

I don't see the need for overlap Obada

[scarlet skiff]

uhhh ngl im getting a lil confused

[grand badger]

a little? You must be a genius lol

[wicked pulsar]

Imagine this:

public void TwoPlusTwoIsFour() {
    return (2 + 2) == 4;
}

[sour fulcrum]

You can go down whatever route you prefer but personally this seems like something your unintentionally making more accurate than it needs to be. You don't necessarily need to correctly check if the enemy "sees" the player when they are hiding in a bush you just want a mechanic where if a player is hiding in a bush good enough the enemy doesn't "see" them. distance checking and/or a specific trigger collider on the bush seems way easier to manage

[grand badger]

I'd understand exactly 0 of these words as a beginner, for sure

[scarlet skiff]

it wont just be bushes, its gonna be trees, secret passages maybe, other stuff, and they might be tall and thin, or short and wide, they would need their own distance for the distance check, and i thought i might as wwell do it with overlap, at least here i can know the exact % of how much the player is inside, but i geuss it wasnt that simple

[wicked pulsar]

Consider the method that I just wrote. This is what we call a "test". It's a method that does some finite thing and returns a result if some logic is true. Does that make sense?

[grand badger]

Can you draw a pic showing a single case in which you think overlap percentage is needed?

[sour fulcrum]

you can use a raycast in addition then

[scarlet skiff]

yes

[sour fulcrum]

because what if it does hit bush first, but goes through it and catches player, it might read that as player is insibile while they are not
This isn't how raycasts work

[scarlet skiff]

well, a RaycastAll does, no?

[sour fulcrum]

then don't use that?

[scarlet skiff]

i need it becayse this

[sour fulcrum]

you can avoid that by just configuring layers

[wintry quarry]

RaycastAll doesn't tell you the order though

You'd have to sort the hits by distance

But yeah really just use layermasks

[scarlet skiff]

if you store stuff in an array or list, the first hting it hits would be index 0, second thing index 1, etc

[wicked pulsar]

Okay, so that method should return true 100% of the time. It wouldn't make much sense if it didn't. Consider wrapping your CalculateOverlapPercentage() method inside a test method like this:

public bool ARectFitsInsideItself() {
  Rect myRect = new Rect(20, 30, 50, 60);
  return CalculateOverlapPercentage(myRect, myRect);
}

This should never return false if your CalculateOverlapPercentage method does what you expect it to do.

[sour fulcrum]

not for that function; regardless just use layermasks

[wicked pulsar]

What tests do is give you an expanded way to write these kinds of things, assess that they do actually pass, then you leave them in like little triggers in case you ever change something in your code that makes them fail.

[grand badger]

@scarlet skiff this is what you need:

var hits = Physics2D.RaycastAll(...);

var playerDist = 0f;
var closestObstacleDist = float.MaxValue;

foreach (var hit in hits) {
    if (IsObstacle(hit)) { closestObstacleDist = Mathf.Min(closestObstacleDist, hit.distance); }
    else if (IsPlayer(hit)) { playerDist = hit.distance; }
}

return playerDist < closestObstacleDist;

[scarlet skiff]

guys i did consider a few other options, i cant go through my thinking process right now, but i thoguht this was the best course, but maybe it isnt, but im thinking i might as well solve this, its a learning experience anyways, maybe someday i actually would requite overlap specifically, and because of this sutaiotn, id know how

[sour fulcrum]

you probably don't even need that

[grand badger]

I was also under the impression RaycastAll returns them ordered

I was the one that recommended use of RaycastAll

[sour fulcrum]

Not trying to shame any learning here, absolutely go down those rabbit holes if you are having fun but for what your asking for you don't need a majority of this and if you don't understand how basic layermask and raycast use works this more advanced knowledge on the subject isn't going to sit as well in your mind

[humble abyss]

Hi all if you have a small cube as a trigger ( acting like as a light switch), how do you check if the lights are on, then turn them off, if the lights are off, then turn them on. I have this but it's not working. I use 2022.3.50f1 ```public AudioClip theSwitchSFX;
public AudioSource myAudioSource;
public GameObject thePointLight;
public GameObject theSpotLight;

void OnTriggerEnter(Collider dd){
if( dd.CompareTag( "Hand")){
//if is active , set inactive-TURNOFFLIGHT
if(thePointLight.activeInHierarchy){
thePointLight.GetComponent<Light>().enabled = false;
theSpotLight.GetComponent<Light>().enabled = false;
}
//if is inactive, set active-TURNONLIGHT
if(!thePointLight.activeInHierarchy){
thePointLight.GetComponent<Light>().enabled = true;
theSpotLight.GetComponent<Light>().enabled = true;
}

      //In Either case play the switch sound
      myAudioSource.PlayOneShot(theSwitchSFX, 1.0f);
    }
}

[scarlet skiff]

honestly i cant read code anymore right now its late and ive been doing it for too long, the logic i have to detect whatever needs to be detected works the way it needs to, it just relies on working overlap % calculator, which i dont havw rn

[grand badger]

@sour fulcrum why does your name look familiar

[sour fulcrum]

lethal stuff maybe?

[grand badger]

no...

welp.. maybe my 5am brain is playing tricks on me

[scarlet skiff]

i do know how layermask works and have at least a basic understanding of raycasts, again i did consider them, you guys have to keep in mind there are other aspects in the game that would provide insight on hwy i chose this system but i cant go into right now, the items on the floor, the ground, the enemies, im at least somewhat confident that this is the best way

[sour fulcrum]

nah layermasks will work

[scarlet skiff]

🫠

[sour fulcrum]

feel free to elaborate when you have time

[velvet holly]

I think thePointLight.GetComponent<Light>().enabled = !thePointLight.GetComponent<Light>().enabled; would work

you're just inverting the value

then you wouldn't need the if statements at all so your code could just look like

public AudioClip theSwitchSFX;
    public AudioSource myAudioSource;
    public GameObject thePointLight;
    public GameObject theSpotLight;

void OnTriggerEnter(Collider dd){
       thePointLight.GetComponent<Light>().enabled = !thePointLight.GetComponent<Light>().enabled;

          //In Either case play the switch sound
          myAudioSource.PlayOneShot(theSwitchSFX, 1.0f);
        }
    }

[humble abyss]

Thanks a lot!!!

[velvet holly]

Happy to help

[humble abyss]

Is there reason why My stuff did't work, it kind of made sense. i thought it did. Also you forgot about the spotlight. Do i just do the same thing you did for the Pointlight?

[wicked pulsar]

You're on your way to getting it. When you are working on a method and need to get it to spit out some result, and its exposed in a simple enough way that you ought to be able to test it in specific scenarios, that's a great time to build tests to make sure that once it works, it keeps working through the life of your project.

[sour fulcrum]

oh im dumb, all good

[velvet holly]

Yeah you can do the same thing for the spotlight. The reason yours didn't work is activeinhieearchy checks if the game object is enabled, not the light component itself. Then you toggled the light component to inactive, but the game object it's attached to is still active

So your if statements weren't checking if the light itself is enabled which is what you're toggling

If you wanted to make the code more generic so you could have an arbitray number of lights, you could do this

public AudioClip theSwitchSFX;
    public AudioSource myAudioSource;
    //Use a list so that you can assign as many lights as you want
    //Referencing the light component directly means you don't have to do GameObject.GetComponent<Light>() which is expensive to perform
    public List<Light> Lights;

void OnTriggerEnter(Collider dd){
        //Iterate through each light in the list and toggle if it's enabled
       foreach(var light in Lights)
        {
          light.enabled = !light.enabled;
        }
        
          //play the switch sound
          myAudioSource.PlayOneShot(theSwitchSFX, 1.0f);
        }
    }
```'

[sour fulcrum]

Out of curiosity for more experienced and/or professional Unity devs, Have you found any valuable use of Unity's Physics Material system?

Wanted to kinda hijack it for referencing data but it kinda locks me out of using it the intended way so curious what i'd be actually missing out on

[velvet holly]

what's the reason you want to do that

[queen adder]

What's the best way to learn C# so I can learn how to learn to prevent myself from tutorial hell and other things.

I solve my own errors and stuff

[sour fulcrum]

It would be nice for me to associate a misc, arbitrary collection of colliders with a shared piece of referenced based data

(i would use tags but i refuse to use tags)

[cosmic dagger]

I'm unsure if I read your comment correctly, but this doesn't toggle if it's enabled; it flips the enabled state to the opposite value . . .

[teal viper]

You do need to at least know C# and unity basics, so you'll need to go through tutorials/manual/unity learn for that. After that it's a free ride. Learn as you go. Look up tutorials for you specific thing, make sure to understand them instead of copying mindlessly. At some point you'll learn to come up with solutions yourself.

[queen adder]

Thank you sir

[teal viper]

The best advice is probably: have curiosity. Don't just accept things as is, but research how and why they work instead.

[queen adder]

Well that's good cuz I'm a very curious man

I truly appreciate your advice

Thank you

[velvet holly]

Is there a difference between those two things?

[velvet holly]

Physics materials are used to determine how rigidbodies interact with each other

why not just make a class with that info

[sour fulcrum]

I know thats why they exist but i don't care about that

[sour fulcrum]

because then i have to add that component to every object with a collider which is abit ehhh

and then also require a getcomponent to try and find it vs. the collider having the reference built in

[velvet holly]

you know what static classes are?

[sour fulcrum]

Yeah

[velvet holly]

why not that

[sour fulcrum]

How would a static class be used in this context

[velvet holly]

you want the same piece of info accessible across every object no?

[sour fulcrum]

Sorry, I'm bad at figuring out what context I need to provide in my initial questions,

I want to check if a given collider has a given piece of referential data

also known as I want tags but i can't use tags so the next best thing

[velvet holly]

I'll pull up the code in a few but I just make my own tag class

so you can have multiple

gimme like 10 minutes and I'll pull it up I'm in a deadlock match

[sour fulcrum]

Nah it's all good

Not really interested in that option right now because it adds a getcomponent into the mix and requires active use of that new component which is a lot less attractive then potentially hijacking the physics collider reference

[velvet holly]

Would you not still need to use getcomponent on the collider and then access the physics material attached?

[sour fulcrum]

In these cases I already have the collider because of various physics events or raycasts

[velvet holly]

https://paste.mod.gg/nuyyuoyyrcli/0 https://paste.mod.gg/syjepqmpdcnw/0

I don't use getcomponent. OnEnable and OnDisable adds/removes them from a static class and you can get a list of components with X tag

just call ObjectTagManager.FindAllObjectsWithTag(Tag)

[sour fulcrum]

I appreciate the suggestion but I'm alright on that for now

[velvet holly]

unless your game uses 0 physics I'm pretty sure you're gonna regret using the physics material to store non physics material data

[sour fulcrum]

I asked the initial question to find out more about those potential regrets 😛

[velvet holly]

The regrets are pretty simple. Your physics objects are gonna have random friction and random bounciness

and it makes your code 100x harder to read cause you have to go "ok this code is accessing my collider's bounciness but that's actually referring to the hp of the player with that collider" or whatever

[sour fulcrum]

When you say random are you actually refering to some sort of involved randomness?

[velvet holly]

I'm referring to the fact that changing the friction and bounciness of your physics objects for reasons unrelated to wanting them to have a different friction or bounciness is effectively random

your objects are going to arbitrarily change how rough/bouncy they are

What data are you trying to store with those values?

[sour fulcrum]

Mentioned it previously but i have no interest in actually using these physics colliders as intended

i don't want them to manipulate the physics at all

[velvet holly]

but what are you using them for

[sour fulcrum]

the material itself

[velvet holly]

Actually I'm pretty sure that changing the physics material asset doesn't update the physics material on every object with that. I think you'd have to reassign the material. Lemme check real quick

[sour fulcrum]

thats not what im interested in doing

[charred spoke]

What exactly do you want to achieve ?

[velvet holly]

It would help if you said WHAT you are trying to do

[sour fulcrum]

the point is that it has a reference to a physicsmaterial asset

i have said what im trying to do

[velvet holly]

no you haven't

[sour fulcrum]

I want to check if a given collider has a given piece of referential data
also known as I want tags but i can't use tags so the next best thing

[velvet holly]

you said you want to change the values in the physics material for reasons unrelated to the physics mateiral

but why

[sour fulcrum]

I never said i wanted to change the values in the physics material

i explicitly said i didn't want to

[velvet holly]

so you just want the name of the physics material?

[sour fulcrum]

I want the reference to the physics material object

[charred spoke]

The next best thing is a component that holds the referential data

[velvet holly]

what are you doing with the reference to the physics material object

[sour fulcrum]

as mentioned previously in the convo i'm not interested in that for the time being, heard though

[sour fulcrum]

using it to identify if that collider is relevant to me

[charred spoke]

Or a completely empty component I call a TagComponent

[velvet holly]

Would a layermask not work better for that?

[sour fulcrum]

the amount of unique usecases here makes that non viable and layermasks are also not viable for any potential modding support

[charred spoke]

The next best thing to a tag would be a component

[velvet holly]

It sounds like you've already made up your mind before asking tbh

[sour fulcrum]

no respectfully i was just asking for potential issues with my hypothetical solution rather than alternatives

i appreciate the help but your kinda stackoverflowing me here 😅

[velvet holly]

you do you dude

[sour fulcrum]

(this was my initial question for reference)

[velvet holly]

Yes, setting the friction and bounciness of a collider

I think you're trying to overengineer your code here. If you want to do that nobody's gonna rip your keyboard out of your hands

[eternal needle]

skimming through the conversation, i also don't see what you want here. the answer to your first question is obviously gonna be yes. It exists for a reason, it's value is if it solves your problem directly.

hijack it for referencing data but it kinda locks me out of using it the intended way so curious what i'd be actually missing out on
Then simply dont use it that way if you're aware already that this is a poor solution. Literally nothing is stopping you from making your own component that has a reference to the data you actually want and the rigidbody.

[charred spoke]

That is generally a horrible idea. How do you plan to encode the data via the physics material? A dictionary? Managing that and making sure materials do not change the way physics behaves would be a nightmare.

[eternal needle]

this doesn't seem to be a case of if the physics material is useful, it just seems like you're looking for justification to code something poorly. obviously no one is gonna encourage you to do it but it's your code at the end of the day

[velvet holly]

Also the fact if your object has a collider and a rigidbody, changing the physics material of one doesn't change the others

using UnityEngine;

public class ComparePhysicsMaterial : MonoBehaviour
{
    public PhysicsMaterial2D material1;
    public PhysicsMaterial2D material2;


    private void Start()
    {
        var col = GetComponent<Collider2D>();

        Debug.Log("Initial material: " + col.sharedMaterial.name);

        col.sharedMaterial = material1;

        Debug.Log("Material 1: " + col.sharedMaterial.name);

        GetComponent<Rigidbody2D>().sharedMaterial = material2;

        Debug.Log("Material 2: " + col.sharedMaterial.name);
    }
}

you're just asking for errors

[sour fulcrum]

I have expressed no desired interest in this

[echo kite]

/paste

[velvet holly]

You have expressed nothing about what you're trying to do other than you want to do something in a way that you know is wrong

[charred spoke]

The how do you plan to hijack the phys mat for storing data ?

[sour fulcrum]

I know that it's an unintended solution but the official intended solution (the tag feature) is unsuitable for what I'm looking for so I was curious what my potential options we're. I know a class based system is likely objectively preferable but as I've previously had no usage of physics materials and I was curious if it was a viable option for me considering it's a built in piece of referential data. I asked the question to know if it was an actually poor solution in practice as due to my lack of using the system I am ignorant of all it's potential usecases

[sour fulcrum]

the physics material itself is the data i am storing

[velvet holly]

everyone has told you it is a poor solution and then you respond "idc I'm doing it anyways"

[echo kite]

https://scriptbin.xyz/jaxovupoxa.cs anyone know why it shakes screen when im not shooting? also aiming no longer works and its because of recoil

[eternal needle]

official intended solution (the tag feature) is unsuitable
idk where you got the idea tag is the official solution. there are tags, layers, and the only thing i wrote as a solution was writing your own component which i believe to be the best from what i gathered. I didnt gather much though other than that you plan to reference this data, which doesnt really mean anything

[velvet holly]

Is there a certain part of this code related to screen shake? I'm skimming through it but not seeing it

[echo kite]

recoil

[velvet holly]

ty

[charred spoke]

But what part? The name? The guid ?

[sour fulcrum]

I've had three reasons for why it's a poor solution which was

-that it modifies the physics of the object (if i cannot use values that reflect the state it would be in without a material this is a legitimate problem)
-that changing materials doesn't do something in a certain way? (I never expected it too)
-that it's a nightmare to manage (untrue without delving deeper into how its used)

I do not wish to come off combative here and I would appreciate if your comments did not give off those vibes either.

[sour fulcrum]

the object

[charred spoke]

What about the object ?

If there is one or not ?

[eternal needle]

there is a lot of code to go through here, you should really narrow it down. "aiming not working" could mean a lot of things
also add more debugs if something is happening when it shouldnt. that'll give you a clue at least of when its happening and why

[sour fulcrum]

Layers aren't viable because of their limited unique options
Tags aren't viable because they are a no-go for modding support

an additional component is my choice if there is a problem in my proposed physics material idea

[sour fulcrum]

the object, for comparison

[echo kite]

i literally said it its because of recoil its located in update mostly and it calculates normal position i think

to revert back to that after i shoot and gun

[charred spoke]

Compare against what ? Unless you plan to have some sort of database linking the material object to some specific data ?

[sour fulcrum]

I would yes

[velvet holly]

What he's saying is your script is handling shooting, reloading, recoil, muzzle flash, and more it seems. It's hard to debug scripts that do so many things. I'm still trying to read through it but it's hard to keep in your head what would be going on in a script when it does this much

[charred spoke]

That is still a hell of a lot worse to maintain and modify than a simple component

Heck you can provide a base implementation and modders can code their own unique versions that do what they want

[echo kite]

its mostly in update and issue is recoil ever since i added it it broke

[eternal needle]

yea i mean this is the part i was asking for you to narrow on "its located in update". just saying recoil the first time is incredibly vague considering the word appears a lot in the script
And still, add debugs so you can specifically see why stuff is happening. If there is code to shake the screen, and the screen shakes when it shouldnt, you should have debugs inside that method printing out every value. If a value doesn't align with your expectation, figure out why

[velvet holly]

You've got an extra opening bracket for one thing cs private void Update() { {

[eternal needle]

and yea u got a method in a method there

though it probably doesnt affect anything, HandleShooting() is in Update

[velvet holly]

What is your reason you're opposed to adding a component to store this data?

[sour fulcrum]

Biggest reason is that it adds a getcomponent call which if i can avoid why not

[eternal needle]

The reason im saying you need to debug it is because its borderline impossible to follow through someones code when theres a bunch of math and logic involved. Just having to figure out the flow alone makes me not wanna go through it (although other people may be more willing than me).
If you can narrow down like to an exact line/lines where the issue is, then its a lot easier to get help.

[sour fulcrum]

And general mangement of this component on what would otherwise be potentially uninteresting objects

[charred spoke]

Unless you would be doing that call 100s of times a frame the perf impact is negligible

[velvet holly]

@echo kite Are you modifying your camera's rotation in a different script

[sour fulcrum]

In the context of collision events and raycasts i could absolutely be doing that much yeah

[bright zodiac]

they keep making getcomponent faster, funnily enough it's even faster in mono than il2cpp

[echo kite]

player movement script handles camera movement but it worked fine before i added recoil

[velvet holly]

I'm pretty sure raycasting 100s of times a frame is more impactful than a getcomponent call. Plus you can cache the component after the first time accessing

[charred spoke]

We use components to identify different body parts and their dmg multiplyier and we fire hundreds of bullets per shot

[velvet holly]

The only thing I can guess from reading this is that the recoil has a reference to cameraOriginalRotation that's only set in Start, so if another script is modifying the rotation then it's trying to recoil based on an outdated rotation variable

again it's near impossible to debug code when it handles this many things at once

[sour fulcrum]

ok but i'm doing those raycasts for a reason so they are staying. Like a lot of things that use tags not all situations are cachable

[jaunty bay]

when i click on a cooking stove, i want it to enter menu that it adds a semi transparent black screen where the cooking game is happening. i also want it so that whenever i left it, anything that happens here wont be reset.

im quite lost on this, anyone can give me hints on where i should look into? i was thinking about something with game objects being inside a canvas, but i had no clue on how to do that.

[velvet holly]

I'm just spitballing here so this might not be the best approach or even actually work, but maybe look into adding a canvas with a panel that's semi transparent over the camera, then using another canvas with a render texture and a second camera for the minigame

[jaunty bay]

ahh second camera, great idea ty

[charred spoke]

Like I said we fire 100s of bullets per shot, we also get multiple components per bullet collision and the perf impact of this is negligible @sour fulcrum

[velvet holly]

I'm not saying to get rid of the raycasts. I'm saying that you're overengineering something that's almost certainly not going to be an issue. I gave you a suggestion with code that didn't involve getcomponent and could easily be cachable and work within whatever modding system you're trying to do

[echo kite]

how do i revert back everything i did today i messed up stuff in inspector

[velvet holly]

Do you use Git? @echo kite

[echo kite]

unity

[velvet holly]

Git is a separate thing

Git is a version control software. It lets you commit changes and then if you need you can go back to a previous version of your files

[echo kite]

i didnt save it there

[velvet holly]

Do you know what git is?

[echo kite]

github?

[velvet holly]

Github hosts git repositories. Related but not exactly the same thing. If you look up how to set up github desktop with unity, in the future you can avoid the headache you're having currently

gimme a minute I'll record a clip to show you why you want it

[echo kite]

i dont need it rn i just wanna revert back so i keep my settings i had few minutes ago

[eternal needle]

start ctrl z'ing and hope it saved far enough 🤷‍♂️

you need version control (git) because it solves exactly what your problem is

[echo kite]

it doesnt work

[eternal needle]

without git, you can very easily lose your entire project in a second. Months of work just 🪄 poof

[velvet holly]

you don't need it rn, you needed it an hour ago

[eternal needle]

then tough luck, you need git.

[velvet holly]

https://drive.google.com/file/d/1aqj_XGFbCUfm47Kb0oC_mSfR6sZ6KX64/view?usp=sharing

This is what git can do

[eternal needle]

take this small mess up you had as an example. people have had corrupted projects before and lost a ton of work, you really dont wanna go through that

[echo kite]

but what do i do now

[velvet holly]

remember what the values were and type them in

then install git and not have to do that ever again

it's 30 minutes of setup to save you hours of headaches or months of work lost

I could literally delete my whole project folder on accident, empty my recycle bin, and then use git to restore my project

Hell with github I could throw my computer into the ocean and then restore my project on a new pc

[eternal needle]

the only other thing you possibly could've checked, if that component was in a scene and you didnt save the scene. Otherwise the old values are overwritten

[velvet holly]

Just be careful with that you don't undo even more work than you intended if you haven't saved in a while

Using version control in Unity

Unity Version Control

• Getting started

Git

Get the latest .gitignore file from here. It should be placed at the root of your Unity project directory.

[velvet holly]

That links to unity's version control. I don't use that personally I use git, but it should do the same thing at the end of the day

Hello, i have some keys in my game and i want wen i pick it to destroy it, but when i pick one i can't pick other. The code is:

public void Interact(Player player)
{
player.AddKey(this.gameObject);
Destroy(this.gameObject);
}

[ripe shard]

You are destroying the key, what do you expect to happen?

[soft creek]

But how i can only destroy 1 key?

[verbal dome]

You are destroying 1 key in the code you showed so I'm not sure what you are asking

[soft creek]

I pick for example the blue key, but when i want to pick up the green key i can't

[verbal dome]

What line is throwing that error?

Double click it

i thought i had fixed this but im getting this again:

Ok, i find the error, you open my eyes, thank

[scarlet skiff]

@grand badger @wicked pulsar in case you guys are curios, i found the issue from yester... and honestly im embarrassed to even say it 🥲

[undone dragon]

js started vr development yall. wish me luck! lets pray that google got all my answers for me...

[eager spindle]

good luck 🍀

from my experience in vr development unfortunately a lot of stuff is platform-dependent

not sure if unity has a centralised solution for all vr platforms to make cross platform vr development easier but vr is nonetheless fun to do

[undone dragon]

can someone help me out? im using the xr interaction toolkit but the "xr controller (action-based)" has been deprecated and i dont know what replaces it. chatgpt is giving me wrong answers and i cant figure it out. any vr dev able to help? never even coded before

[scarlet skiff]

update does not run in abstract classes even if a subclass of the abstract class exists on a live gameobject?

true or false

[timber tide]

Log it ;p

[eager spindle]

You're overriding Update in a way that it doesn't call Enemy's update, only the inherited class.

In Enemy, make the function virtual

In inherited classes, call base.Update(); in the overridden Update functions

[scarlet skiff]

👍

[sweet pendant]

Yo guys I’m making a first person shooter game, I made the camera rotate with the mouse but the player doesn’t move accordingly with the camera anyone knows the solution?

[grand badger]

yup! So you're doing something like transform.position += transform.forward * Speed * Time.deltaTime;, right?

this inherits from currentPos += dir * magnitude;

so, to change the direction, you gotta adjust dir -- instead of transform.forward, using camera.transform.forward... kinda

float magnitude = Speed * Time.deltaTime;
Vector3 dir = camera.transform.forward;
dir.y = 0; // assuming you only move on XZ plane, not height
transform.position += dir.normalized * magnitude;

[wintry quarry]

You would need to normalize that direction after setting z to 0

Also this doesn't account for horizontal

[grand badger]

yeah tried to leave it vague with just a generic explanation 😛

in reality I'd go with var dir = Vector3.zero; and build up from there, adding vectors relative to the camera on dir, based on input

[mortal ginkgo]

how do i make him unblur?
he is 32x32
also his name is james duckman

[thorn holly]

Is the imported image blurred at all or just the unity model?

[fickle plume]

@mortal ginkgo This is a code channel. Did you open the manual link I posted?

[mortal ginkgo]

i did and learned nothing from it

[fickle plume]

Have you tried reading the Asset Settings section? Also don't cross-post, in unrelated channels as well.

[mortal ginkgo]

nvm i got it

[grand badger]

for reference to anyone interested: switch "Filter Mode" from "Bilinear" to "Point" (and consider enabling mipmaps)

[fickle plume]

It was answered already in the appropriate channel.

[mortal ginkgo]

i did an oopsy
anyone wanna vc with me and walk me through making something?

you don't have to talk

[fickle plume]

If you have a question, ask it in the appropriate channel.

[mortal ginkgo]

it is about coding

it's just hard to explain in text

i wanna screenshare and talk

[fickle plume]

Illustrate with a video then.

[mortal ginkgo]

it'll have to be very very short for discord to accept

[fickle plume]

You can post up to 50 mb files here

[mortal ginkgo]

and videos are big

[fickle plume]

If you need more than that then you are looking for a course or a tutorial. Which you can find in the pins.

[steel smelt]

https://dontasktoask.com

[mortal ginkgo]

ok fine then

i'll just ask how to make the thing i want and hope what i already have doesn't break it

i'm making a top down shooter but the player character is like vampire survivors so i don't want him to rotate, i want a cursor ro spin around him in a circle following the mouse

how would i make that?

[fickle plume]

You break it up into simple pieces and lookup how to do that.

[sweet pendant]

I’m using rb.MovePodition

[grand badger]

same rules apply -- code was more about direction calculation

[sweet pendant]

Ok thanks

[grand badger]

np

[mortal ginkgo]

-_- what's the point of this channel then

[fickle plume]

To help people understand learning materials they have trouble with. Not do anything you request for you.

With rotation you start with this https://www.google.com/search?q=unity+look+at&oq=unity+look+at

Learn to use search engine and do manual examples.

Starting with !learn courses would teach you most of that stuff.

Right bot is dead. This https://learn.unity.com/pathway/junior-programmer

It's in the pins, like I've already mentioned.

[mortal ginkgo]

that is in 3d

[fickle plume]

Unity is 3d. You clamp axis you don't need

Probably should start with https://learn.unity.com/pathway/unity-essentials instead. Will teach you engine specifics first.

[polar acorn]

Not rotating is easy, you get that for free. Just don't add in code that rotates it

[brittle isle]

https://paste.mod.gg/bocbbzuvqnpr/0 For some reason, my player refuses to decelerate and slide on ice. While I enter there, it just stops. Is something overriding my functions for it?

[wintry quarry]

Your code is just doing this:

            Vector2 newVelocity = new Vector2(
                    inputHorizontal * speed,
                    rigidbody2D.velocity.y // Prevent upward launch
                ); // Prevent upward launch
            rigidbody2D.velocity = newVelocity;```

so you're always setting your horizontal velocity directly to whatever your current input is * speed

[brittle isle]

so is there a way to make it decelerate? I'm kinda lost myself... I thought it would decelerate after leaving it.

[rich adder]

seperate the inputs from the movingVelocity ?

[wintry quarry]

don't set it directly immediately to 0

as you are now

[rich adder]

use something like MoveTowards or Anim Curve to bring value back to whatever for a smoother transition

[hardy ibex]

i started learning unity 2 days ago and i started by just making a new 2d project and look up how to do stuff as i go. Should i follow tutorials where i dont really understand everything thats happenieng yet and learn it later or should i make sure i actually know what everything does and why they use it?

[timber tide]

Well, first off know your c#, but other than that I suggest mixing it up with Unity tutorials and tutorials on youtube to keep you interested

[willow hill]

I've been looking for people with zero experience who might like a crash course in programming (C#) with Unity. If you're an adult, I'd be willing to do this via voice call. I did this for my friend last week, and it was a fun teaching experience for me, and a productive lesson for him.

[old pier]

Hi, im interested in learning code to make a game, where should i start? Can anyone recommend some youtube tutorials and guides please

[fresh silo]

Do you have any other programming experience?

[thorn holly]

!learn a few tips: don’t use ai to generate code, don’t use code from the internet unless you understand every line, id recommend doing unity learn first a bit to get the basics and dive right in, we’re here for when u get stuck

[old pier]

I have some basic knowledge of Java

[old pier]

Ok, ty

[thorn holly]

!learn

Is the bot broken?

[thorn holly]

Unity learn has a bunch of tutorials I was trying to link it with a bot but it won’t work

https://learn.unity.com

[thorn holly]

That’s good, unity uses c# which is quite similar to Java

[fresh silo]

This should be a little easier for you then

[old pier]

Ok, i will start doing this rn, thank you very much guys!

[hushed hinge]

i have a question, since i have that if one of the players dies, both of the players respawns to the checkpoint, but is it a good thing or should i have them respawn sperately and not together?

[wintry quarry]

Only you can answer that. It's your game design

[ebon sapphire]

Can someone tell me what I did wrong? for some reason my character wont jump at all, even after the game is unpaused. I'm able to move around, and i was able to jump until i changed GetKey(KeyCode.Space); to GetButtonDown("Jump");. https://pastebin.com/8S4Mfwbk

[fresh silo]

How do I fix these errors, there were two of the same scripts, and now these won't go away

[polar acorn]

Restart unity. If they're still there, you still have a duplicate

[fresh silo]

I did restart, but I don't see any duplicates

Ill try again

When I open up the Unity project, should I select, "Use Safe Mode"?

[polar acorn]

Doesn't matter unless the error is in an editor script

Search your project for classes named PlaceLandmine

[fresh silo]

Thank You! It's fixed

[willow hill]

Look in your input manager and see which key the button "Jump" is associated with. It might not be the spacebar.

[ebon sapphire]

its still not jumping and this is my input manager

[willow hill]

If you change it back to using KeyCode.Space, does it still work again? Maybe you changed something else?

[ebon sapphire]

it is GetKey

[sterile radish]

how can i save and load a list of scriptableobjects whilst using json?

[ebon sapphire]

But the main reason i don't want to use it now is because of the fact that my jump isn't consistent, and i heard that GetButtonDown is more consistent with jump height.

[willow hill]

GetButton and GetKey check every frame to see if the button/key is down. GetButtonDown and GetKeyDown only check once, and then not again until the key/button is released first.

It could be a problem with how "grounded" is being set. Try using GetButton("Jump") and I bet it will work.

[grand snow]

not check but GetKeyDown returns true if the key was pressed down this update

vs GetKey which is "is this key held at all this frame"

[willow hill]

Yes. Sorry, that's what I meant.

[ebon sapphire]

So jumping works with GetButton, but I want to solve the issue of my jumping being very inconsistent

[willow hill]

I was about to advise you on that, actually. I think I know what's happening.

Try this: In your update, add:

if (!IsGrounded())
Debug.Log("not grounded");

When you hit play, you'll get a bunch of logs because your player starts in the air, but I think you'll continue to get more, even when they appear to be grounded.

[grand snow]

Can you explain more, you could parse json and create scriptable objects in the editor or export scriptable objects to json in editor/runtime.

[grand snow]

none of your videos work for me 🤔

[willow hill]

Ok, I see. So it's not what I thought it was.

[willow hill]

The last video showed that he doesn't get the Debug logs I suggested while grounded.

[grand snow]

the boxcast has a very short distance of 0.5?

also not sure why GetComponent is done twice to get the size x AND y... You should avoid doing GetComponent a lot (do it in Awake/Start once) @ebon sapphire

[hardy ibex]

if i have 3 identical objects with the tag "exampleTag", how would i reference all objects with that tag at the same time in code like if i want to modify the same variable in a script in each of them

[grand snow]

A list/array of them?

[hardy ibex]

how exactly would i do that though

[grand snow]

[SerializeField]
List<MyThingy> myCoolList;

foreach(var thing in myCoolList)
{
  thing.DoStuff();
}

[hardy ibex]

k thanks

[ebon sapphire]

how should i change it?

[grand snow]

lists and arrays are basic c# so you may wanna read up on that to make things easier

[willow hill]

See what you did in Start for your Rigidbody? Do the same for your box collider. This keeps a reference to that component for future use, which is generally better than using GetComponent in Update.

[ebon sapphire]

so something like this?

[willow hill]

Yup!

[ebon sapphire]

so what could be causing GetButtonDown to not work but GetButton to work? and how would i fix it?

[grand snow]

if we wanna be pedantic you should get bounds once to a var.

[sterile radish]

my game has craftableItem scripting objects and a craftedItems list. so for example, if i craft a battery scriptableobject during runtime, it gets added into that crafteditems list during runtime as well. I was wondering how i could save this into a json file since jsons can't save scriptableobjects

[grand snow]

You should seperate how you represent "game configuration data" and "runtime data to save". E.g. You have scriptable objects with data for how weapons work. You have another class that has an id of what weapon it is and some other extra custom data. Then you can save and load the runtime data without issue.

[sterile radish]

yes, i have something similar in my game which is a script called PlayerData which like you said is seperate from the game configuration data. in this class i have a string list of crafteditems id (which are just the name of the craftedItems) but im just unsure how to link this list to the actual craftedItems list and how i would get a craftedItem from a string from this list

[grand snow]

well if you have a list in your player data of weapon ids for example, then you can have a Dictionary of your weapon data (where the key is the id) so you can easily retrieve the scriptable object. Pretty simple stuff.
e.g.

Dictionary<string, WeaponData> allWeaponData;
...
public WeaponData GetWeaponData(string id) => allWeaponData[id];

you would have a list or load all your weapon data assets and put them into the dictionary on game start so its ready for use

[sterile radish]

im sorry i dont think i understand what you mean by having a list of all the crafted item data assets and then putting them in a dictionary. are you saying that i should use the crafted item id list the load the scriptable objects into a dictionary by just using their itemId as a key and doing the same thing in reverse for saving the crafted items?

[grand snow]

No i was giving an example on how you can retrieve the data easily with just a string id.

wasnt that the problem, how to load the data asset with an id?

[sterile radish]

yes, that was the problem

[sterile radish]

actually after further insight and practicing, your solution worked for me, thank you very much!

[vale berry]

Could someone help me out with making my first survival game kinda like minecraft but not voxel? I just moved to unity from Scratch

[polar acorn]

Tutorials are in the pins

[vale berry]

ah ok

[polar acorn]

You are going to need to learn how to code first

[vale berry]

I could be like Dani and say hippity hooppity, someone code is now mine

legally

not illegal

[quiet sandal]

Then its not your game now is it

[vale berry]

it is called borrowing lol

[quiet sandal]

fair

[short grove]

hello guys, i was wondering how can you store a data that been trained and generated by machine learning? i want to see if its possible to make the ai use that data instead of generating one again?

[quiet sandal]

but what i recommend is learning how the code works so if you need to make tweaks to it you can

[vale berry]

I would do that

[thorn holly]

You can steal code, everyone does it all the time on the internet…you just need to know what it means or else it’s useless since if something goes wrong you can’t fix it

(Steal code from like a stack overflow answer not an actual game)

[short grove]

anyone open to answer this?

[teal viper]

Depends. What framework are we talking about?

[teal viper]

Also, it's probably better asking in #1202574086115557446

[short grove]

ok

[short grove]

its a general question i had, didnt build it yet

[teal viper]

There's nothing impossible in general. It depends on your implementation (or the implementation of the framework you're using)

[short grove]

i see

because by using nueral network, it requires a data set to be trained on. after beign learned i wonder how can we extract the genrated data so other ais use it without generating one

im using python

[short grove]

the method with weigh-input-hidden-output

[teal viper]

You can't extract the data(assuming we're talking about training data). After training you only have the weights. Or parameters. These you could save as the model parameters. The exact method would depend on the used framework, unless you're writing your own from scratch.

[short grove]

i see

[short grove]

thank you for the info

[teal viper]

This is unrelated to unity at all btw. Unless you're using unity provides frameworks. At which point ask in #1202574086115557446 . If you're using a third party framework, better ask in their community. If you're writing your own, you'll need to research and learn a lot. Maybe look at the pytorch or a similar open source framework code and ask in their communities.

https://paste.myst.rs/kc07n4c5 does anybody know how i could use scriptable objects to spawn more asteroids when the original one is destroyed im kind of confused on how to go about it i kinda have an idea on what to do

[timber tide]

You should have a prefab that you insert the SO data into and just instantiate that prefab over and over

[pure drift]

would i have the prefab in the bullet script

[timber tide]

            // spawn 2 that are 50 percent of the original size 
            // once the second ones are hit spawn two more that are smaller from the original ones
            // then they dont spawn anymore when destroyed so basically three stages```
So you want 3 different prefabs, 1 for the big astroid, 1 for the medium astroid, and 1 for the smaller astroids

So 3 different prefabs and 3 different SO instances

Well, actually you can use a single astroid instance and have the SOs have the identity of it, but according to what you're doing with the SO it seems like you should just make 3 prefabs

[pure drift]

ohh ok thank you i will try that out

[timber tide]

Basically when you Kill() the first astroid prefab, make it instantiate multiple medium astroids, ect

I'd have each additional prefab reference local to the astroid itself and not the bullet

and have the astroid itself instantiate the next ones

[pure drift]

so i should work off of my asteroid script directly and not my bullet script?

[timber tide]

You want some method on the astroid to call (when the bullet collides) so the astroid itself should clean itself up and instantiate the next instances

Oh you do have some singleton manager that cleans it up? Either way, use OnDestroy Unity method or your own Destroy method local to the astroid

[pure drift]

ohh ok thank you i will try this out

i have a replay system that im making that current works by recording a "data point" class every frame and saving it on a list to which it can be played back.
it works, but with the down side that just one second of data takes up one kb, this is bad considering that this is only from storing the players postion and mouse positon, and as im also planning on adding more variables to a data point.

my question is if there is a way that i can shrink down the the size of a single data point class as much as possible?

[timber tide]

Most games replay data by just storing input and simulating that

[cyan osprey]

thats pretty much what i do, all of the data points are stored in a list and when its played back a "dummy" player is spawned and every data point is passed into it

[timber tide]

I mean, a kb a second doesn't sound unreasonable and I assume you're not storing this data at all, right

[cyan osprey]

i mean when this data is put on a list, where is it stored, RAM?

[sour fulcrum]

I don't know much about the subject so just ignorantly throwing an idea your way but one thing you can do potentially is ensure that if your storing position and rotation per frame you don't save it if it hasn't changed since last frame as you can just refer to the last unique entry

[cyan osprey]

and yeah im going to be storing multiple instances of that data

[cyan osprey]

yeah that does sound good

like if the player is not moving

[sour fulcrum]

but yeah like Mao suggested a lot of games do this by recording the inputs instead to re-create the same experience. But I think that depends on how reliant you are on certain physics things(?) and such

[cyan osprey]

also this might be a strectch, but would it work if i used smaller data types like 16 bit?

[timber tide]

If you're writing to a file it doesn't necessarily need to be loaded into mem and you can chunk the data up for what is to be loaded for you do manage to create some very large clips.

[cyan osprey]

wdym chunk up the data

[timber tide]

don't read all the data in at once and deload the previous points

[cyan osprey]

what would i use to do to that

this is the code i use to record data

   // loop that will run every frame, creating a new datapoint class and adding it to the queue list
    public void Update()
    {
        if (isRecording)
        {
            // create a new datapoint class
            DataPoint dataPoint = new DataPoint(
                player.transform.position.x,
                player.transform.position.y,
                cam.ScreenToWorldPoint(Input.mousePosition)
            );

            // print the contents of datapoint
            print(dataPoint.x + ", " + dataPoint.y + ", " + dataPoint.mousePos);

            // add the datapoint to the list
            data.Add(dataPoint);
        }
    }
}

public class DataPoint
{
    // store the players x,y position
    public float x;
    public float y;

    // store the players mouse position
    public Vector2 mousePos;

    // constructor
    public DataPoint(float x, float y, Vector2 mousePos)
    {
        this.x = x;
        this.y = y;
        this.mousePos = mousePos;
    }
}

[timber tide]

You can write using Json or use the binary formatter class but honestly I wouldn't worry too much about this unless you do run into problems

[cyan osprey]

ok yeah thanks i was just thinking that i will eventually take up more space as i will be store more things than just the player posion

[timber tide]

Yeah, it's what I'm thinking off the top of my head, but there's probably other ways around it

[eternal needle]

probably binary writer/reader instead of formatter given the security issues of it

[timber tide]

if it's temporary I wouldnt worry too much

[cyan osprey]

what issues

[eternal needle]

just a better practice to not use binary formatter at all
https://learn.microsoft.com/en-us/dotnet/standard/serialization/binaryformatter-security-guide

[cyan osprey]

alr thanks

[eternal needle]

do you need the replay to be entirely accurate? you could also choose to not record certain frames if you're storing the current position. from what you said above, 1kb in 1 second would be like 256 floats. you have 4 floats in a data point, so i assume you're recording roughly 60 frames per second. This could probably be cut in half with almost no visual difference

One issue i think, because you're not recording the time, this might end up not being accurate in its current state anyways

if your replay logic is the same as your recording logic then the replay wont be guaranteed to run in the same duration

[cyan osprey]

yeah it is recording in the main loop, and the replay system also does it at the same speed

[timber tide]

input simulation would probably save you a lot of data as even holding input/analog can be simply be flags for when those values change

[cyan osprey]

 private IEnumerator Replay()
    {
        while (currentIndex < data.Count)
        {
            dummyInstance.transform.position = new Vector2(data[currentIndex].x, data[currentIndex].y);
            currentIndex++;
            // Wait for next frame
            yield return null;
        }
    }

like this

[eternal needle]

where does it do it the same speed? nothing about your code cares about when a position happened

you should test this yourself at like 60 fps then set the target frame rate to like 10

[timber tide]

In networking though, there's a similar usecase for this stuff and even though you do simulate input of clients you do have points to resync the character completely

[cyan osprey]

well the recorder runs in a update loops at 60fps, and the replayer uses a yield statement to wait for the next frame so in practice it should both run at the same speed

[eternal needle]

are you recording and replaying at the exact same time? this doesnt seem to be the case given the video above
I really think you should just try it, record when running at your normal frame rate then set the frame rate much lower when replaying

you cant guarantee the game will always run at 60 fps

a lag spike for the user will make this inaccurate

[cyan osprey]

no, rn i have some buttons that i press to record,stop and replay

[cyan osprey]

so would it seem better to use someting like a fixed update to record and replay?

[tulip karma]

hey guys, im currently experiencing an issue having prefabs or sprites show up for my ingameitems using a creatorkit if anyone is able to help me

[woeful carbon]

When apply a child UI/canvas object it has rect transform and my parent object is a sprite with normal transform how can I correctly transform the piece to its correct position without it being stuck at 0,0 (or whatever coords I initially set the object to)

[eternal needle]

hm i dont know if there would be downsides to fixed update here, but i'd likely still do my own logic to run it how often I want. Then also record the time so you know which position it should actually be going to

[cyan osprey]

honestly yeah i think i would be better if i cut the data in half by recording every other frame

@eternal needle do u know if there is a function in unity that can do that

like a slower update function

[eternal needle]

this is very vague, you should specify what issues you're having. look at the #854851968446365696 on what to include when asking

[eternal needle]

it doesnt have to be every other frame, this shouldnt specifically care about the frame count because thats still the same issue. Just store and check the time, have some threshold about how long it should be until you record the next position.
And as for the function to do it, you just make it using Update.

[cyan osprey]

alr that makes sense

thanks btw

[tulip karma]

@eternal needle im currently doing a computer science project using unity and the creatorkit: beginner code, where you have to add customizable items with custom item effects. i followed all of the instructions using 2022.3 3D URP, ive created the custom items and their custom weapon effects, but in the inspector when i assign both a sprite and a prefab to represent the item in game, neither of them appear. Im not entirely sure if theres something inherently wrong in the code for the usable items using the creatorkit (i doubt it) but i have a screenshot here as well of the inspector with both prefab/sprites selected for the usable item.

even when i create an in game item, without adding the effect and script i make, where its barebones with a world object prefab it still wont allow me to place it in the scene

ive also attempted to create an empty object, for example a cube, in the scene and add the item effects to it, but it says its not monoscript

and changing it to monoscript goes against the steps in the tutorial and i get a million different errors in the console

[eternal needle]

im a bit confused what you mean

in the inspector when i assign both a sprite and a prefab to represent the item in game, neither of them appear
The object you shown looks like a scriptable object, so it's not something that goes in scene at all. If a game object is using this scriptable object, i assume it's going to be reading the sprite and assigning that to some UI

which object in specific isnt functioning as you expect?

[tulip karma]

the agility potion, the really big staff, and the world's coolest shirt which are the 3 blue box items, could i possibly send you a link to the exact spot in the instruction that had me create those items?

its saying that when i apply a World Object Prefab, the scriptable items i made, would appear in the world as that prefab, but when i select one absolutely nothing happens and i cant place it

[eternal needle]

scriptable objects dont go in a scene, you cant place it in a scene. there is likely some code to instantiate the WorldObjectPrefab on your scriptable object

[eternal needle]

yea you can send it but i also haven't gone through the tutorials ever. I can see if theres any glaring issues though

[tulip karma]

okay ill send it here https://learn.unity.com/tutorial/customize-your-game?uv=2022.3&projectId=5d48025dedbc2a0020e85be2#6542071cedbc2a50f555fa14

im currently on the customize your game portion, at "create a usable item"

[eternal needle]

i think you might just have a misconception at what this scriptable object is for then. are you still trying to place it into the scene?

because thats not what its for

[tulip karma]

i think i might, because the scriptable objects are meant to be used in the game. for example a few other students have it uploaded, and the three objects they needed to create are in their game. do i need to LINK these items to an existing prefab?

[sour fulcrum]

yes

[eternal needle]

some game object will need to reference your usable item at some point and use it as described in the guide.
World Object Prefab: The 3D GameObject that will be created to show the Usable Item in the game world when it is spawned. If this is left empty (null), the item Sprite will be used instead.

[tulip karma]

is my issue that im trying to use prefabs or sprites that already exist and are attached to items already?

[sour fulcrum]

a scriptableobject is referenced by a monobehaviour the same kinda way an ikea instruction manual is found in the box of your new chair

[eternal needle]

the scriptable object is just used to hold information, thats all. in this case, its holding what information to actually spawn. It holds a reference to a prefab, it holds a reference to a sprite. neither of these are spawned in your scene
Something else needs to take your data container (usable item) and actually do something with it

[tulip karma]

okay i think i get it, so i have to attach that information to a 3d object. i was under the impression that's what i was doing when i selected World Object Prefab - potion_prefab

i just assumed it would automatically create that item, using that 3d model

[eternal needle]

id assume the guide would have some code or section on how to actually use those usable items but yea didnt look through it all.

[tulip karma]

ill scan through everything again.

thank you for your help

a message to the world to not implement an inventory system to a 2 days game jam as a beginner

https://paste.mod.gg/eapxtrrkzmfw/2

someone plz

[candid plover]

I'm trying to Recreate a fnaf game in a 2D universal Environnement,everything was going well until i needed to code the "New Game" button,the code itself is working but when i press the button in play mod it doesent do anything.The code is attached under the button named "LoadGame" and the scene itself is named "12AM".The code is normally supposed to switch scenes.As you can see on the screen there's the script and the "On Click ()".And there's the script.Please someone help me and if needed i could provide other screenshots🙏😔.The tutorial i'm following has a 2019 version of unity so the steps are sometimes different.

I suck at coding 😔

[timber tide]

Log a message inside of your method

[jaunty bay]

yea try debug logging the Load12AM to see if the button works first

[candid plover]

What ?

[timber tide]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Debug.Log.html

[jaunty bay]

Debug.Log("Message");
is usually used to send you a message to your debug terminal. it can be used to check if a function works or not, so try add it in Load12AM to see if the button does indeed runs the Load12AM function

[candid plover]

Where's the debug terminal ?

(also thanks for helping me)

[jaunty bay]

by default, its the Console tab on bottom of your screen

[candid plover]

ah yes

and what do i do with it ?

[jaunty bay]

that tab will give output from Debug.Log("Message"); from your script

go ahead and try it

[sour fulcrum]

If I have a flags enum value how can i iterate through the selected choices?

[candid plover]

where do i put the Debug.Log("Message"); ?

i know in my script but where ?

[jaunty bay]

read my messages again, i told u whr

[candid plover]

like this ?

[jaunty bay]

id recommend asking chatgpt about simplest stuff if u r still confused as much

and yes, like that

now try to press the button

[candid plover]

i get errors on unity

cant launch the game

[jaunty bay]

have u try to ask an AI to help u?

[candid plover]

yes

i asked chatgpt

[jaunty bay]

im not saying you should completely use it to write your codes, but when you asks such simple questions, it will explain to u in the suitable level you wanted

what was the error?

[candid plover]

i fargot to save the visual studio file mb

when i clicked the button nothing happened again

[jaunty bay]

nw m8 haha

[jaunty bay]

okay good, now what do we know from that information

[candid plover]

im trying tio get help abt that 😭

[jaunty bay]

well, youve put the debug log inside the function, but the debug log didnt come out any kinds of message from the console did it?

any conclusion on that?

[candid plover]

🥀

[jaunty bay]

the function isnt being called (executed)
