This would cast it down

What's right with it?

[neat bay]

by rotation calculation are we talking about this? : Quaternion.Euler(hit.normal * 90)
or this? : Vector3.down

[teal viper]

The former

[pallid nymph]

so... you need to check if it hits anything... I assume it does not in the first 3 cases

but also, yes, what dlich is saying 😦

[neat bay]

mm i should be using a collision instead of a raycast right?

and get the normal of the collision instead

https://docs.unity3d.com/ScriptReference/ContactPoint-normal.html this would work right?

[teal viper]

We don't know enough about the use context to answer that.

[neat bay]

the player throws a sphere in the direction they're facing. Then, when the sphere collides with a surface, a circle is instantiated that looks like this ^

I just need the circle to rotate to a point where its flat on any wall of surface

[teal viper]

Yeah, a collision event might be better

[exotic hazel]

hello so i just mass placed 10000 trees in a terrain but now my game lags when i go near it. so what do i do so my game doesnt lag much. like if i can not render the treees far away with some code how do i do that

[teal viper]

Reduce the camera dar clipping plane

You can also configure the culling distance based on the object layer
https://docs.unity3d.com/ScriptReference/Camera-layerCullDistances.html

[exotic hazel]

ok ill try that

[teal viper]

But really you should start with profiling and figuring out if it's a CPU or a GPU bottleneck

[stone elk]

am i able to copy a component from a unity project and paste it in another project?

[languid spire]

no

[stone elk]

ok

[wintry quarry]

Assets -> Export Package

[languid spire]

? That's for Assets in the project, not for components

[wintry quarry]

It's the closest you would get to "copying a component" from a project

Twas a vague question

[languid spire]

I think it was Copy Component/Paste Component Values (as new)

[gentle vortex]

so i made 3d speedline particles, now, is there a way to make them always render above the environment?

(the particles are clipping through the floor)

[mossy crest]

Been programming a little while, just learning C#/Unity now - why are behaviour class variables static and not this.variable?

[languid spire]

becaise this denotes an instance and static variables are not bound to an instance

[mossy crest]

but if i had 3 game objects controlled by the same script, surely they'd all affect eachother?

[teal viper]

Maybe clarify what you mean first

[eternal needle]

what variables are you talking about? because Behaviour doesnt have any static values as far as i know

[languid spire]

each gameobject will have it's own instance. static varialbe will be shared by all 3

[mossy crest]

like if i have a PlayerCharacter with a health variable, damaging Character1 will damage Character2

the unity tutorials don't use instance variables

[teal viper]

Then it's an issue with your code, and not something intrinsic to behaviour variables

[languid spire]

yes they do

[teal viper]

Can you provide an example?

[wintry quarry]

As a beginner you should stay away from static variables until you understand what you're doing.

[wintry quarry]

Only if you use static variables.

[mossy crest]

PlayerController.ChangeHealth affects currentHealth instead of this.currentHealth

[wintry quarry]

Only if it's static

But also nobody knows what ChangeHealth does

You'd have to show the code

[teal viper]

then you made the variable static. So of course it would behave as a static variable

[wintry quarry]

You think we have specific tutorials memorized?

[eternal needle]

if you made it static, then its static. Also you dont have to explicitly write this unless its ambiguous

[mossy crest]

https://pastebin.com/19hNrS0S

[wintry quarry]

Each instance of this script is completely independent

[mossy crest]

so, because ChangeHealth() isn't a static method, it affects instance.currentHealth instead of class.currentHealth

[teal viper]

It's not static here. So the issue must be elsewhere. Or you're misinterpreting what is happening.

[wintry quarry]

There is no class.currentHealth in this example

[mossy crest]

i might be misinterpreting then

[languid spire]

in that script there is no such thing as PlayerController.ChangeHealth

[mossy crest]

line 43

[mossy crest]

in c#, declaring a variable in the class/outside of initialisation makes it an instance var and not a class var?

[languid spire]

ChangeHealth is an instance method and so cannot be invoked using a class name reference

[wintry quarry]

Member variables are instance variables by default yes

[mossy crest]

i see, that's where my confusion lies then

Thank you all

[teal viper]

To be precise, you're confusign instance fields with static fields. Class fields are just fields declared in the class and include both static and instance fields afaik.

[wintry quarry]

"class field" isn't really a term that's used in C#

It doesn't have any specific meaning

[teal viper]

but the loose interpretation would be that it's fields declared in a class.

[gentle vortex]

solved my previous issue, though how does one control a particle system through code?

ex: change the color gradient in Color Over Lifetime

[wintry quarry]

Have you checked the scripting reference for the particle system?

[gentle vortex]

i was looking for it while asking the question

man i really gotta make sure i have to ask a question before doing it

[barren vapor]

Make them smaller. Just put it right in front of the camera. Don't make it too big

[mossy crest]

wait a minute

if things are instance variables by default

whats the point of this.

when you have an instance variable and a static variable of the same name?

[steep rose]

probably used for clarity

[slate badge]

I used this code to freeze my character

But it just doesn't work (anymore)

[steep rose]

explain

when did it not work

[strong wren]

Or when parameter is the same name as an instance variable.

[mossy crest]

why would anyone do that ;-;

[shell matrix]

heii, i need help doesn t work to switch the state, just manually i dont know what to do

https://paste.ofcode.org/i3EDmXXffmBvhNMakH9xYJ

[eternal needle]

Quite common when using a constructor, or a method which sets a variable

[slate badge]

I made a code where if u press q, ur character would freeze, after a certain amount of time, an invoke would make the character unfreeze

[eternal needle]

I also did write this up here
#💻┃code-beginner message

[mossy crest]

oh right

[wintry quarry]

No it's for when you have a local variable and an instance variable of the same name. Your example is a compile error

[mossy crest]

those make sense

[wintry quarry]

this can also be used anywhere you need a reference to the object itself. I.e. as a function parameter

[tender wharf]

Hello gamers, would anyone know why wheel colliders are clipping into the ground?

Last two days I've been trying to figure this out with no success

[slate badge]

Can anyone explain why my character won't freeze even when the rest of this code works?

[wintry quarry]

How are you moving the car

[tender wharf]

That's the thing I'm trying to get it to move xd

[wintry quarry]

How are you moving the character?

[wintry quarry]

You need to be moving it via the Rigidbody

Both of you

[tender wharf]

The colliders themselves spin on input, but the rigidbody doesnt move at all

[stark perch]

why is this not working 0one of the objecs has the code and both have these settings for a rigidbody and collider

[wintry quarry]

You'd have to show how you tried to move it

[stark perch]

my debug is not going off

[wintry quarry]

You're using the 3D function for 2D components

Use the 2D versions of the functions

Y'all should be in #⚛️┃physics btw

[slate badge]

Never mind I found the problem, for some reason when i used both .FreezePosition and .FreezeRotation in the same script. Neither would work

So I removed .FreezeRotation

[wintry quarry]

You did it incorrectly. Those need to be composed with |

They're bit flags

[slate badge]

Example?

[wintry quarry]

There's an example in the docs: https://docs.unity3d.com/ScriptReference/Rigidbody-constraints.html

if you want to freeze all you can use either:

m_Rigidbody.constraints = RigidbodyConstraints.FreezeAll;
// OR
m_Rigidbody.constraints = RigidbodyConstraints.FreezePosition | RigidbodyConstraints.FreezeRotation;```

[slate badge]

May I ask, what is the point of using |?

Why not js add seperate codes

[wintry quarry]

it's the bitwise or operator

[wintry quarry]

because then you would need a list or something

instead of storing everything in a single int field

this lets us use a single int to store all the information

[slate badge]

Oh ok alr thanks

[wintry quarry]

here's an explanation if you want to learn how it works https://pressbooks.lib.jmu.edu/programmingpatterns/chapter/bitflags/

[tender wharf]

public class DriveController : MonoBehaviour
{
    public WheelCollider[] wheels = new WheelCollider[4];
    public float torque = 200f;


    private void FixedUpdate()
    {
        if (Input.GetKey(KeyCode.W))
        {
            foreach (var wheel in wheels)
            {
                wheel.motorTorque = 500;
            }
        }
    }
}

Here you go gamer

[wintry quarry]

show the inspector of the rigidbody

[wintry quarry]

try reducing the mass to 1, just for testing purpsoes

[tender wharf]

Still same behavior. I just find it really weird how the box collider doesn't clip through the ground while the wheels do

hmm maybe i should have moved the position of the wheel colliders via the Center property?

[calm forge]

someone pls help idk what i am doing wrong what does this means 😭

[tender wharf]

it means that one of your properties in your script is null

[slender nymph]

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[calm forge]

ya i get that but my object has a variable defined

[slender nymph]

show it

you'll need to also show which line the NRE occurs on too

[calm forge]

sorry i dont know much about coding mean?

[slender nymph]

huh?

[cosmic quail]

it means show which line the error happens on (double click the red error text to go there)

[tender wharf]

I think that I found the solution to my problem, the orange lines in wheel colliders should be pointing downwards

Now they actually collide with the terrain, god damn i wasted 2 days on this

Gonna have to rotate the model in blender

[calm forge]

um what if their is no red error text

[slender nymph]

my guy, you screenshot it

did you even bother going through the steps outlined in the link i sent? it explains how you can find the line the error occurs on as well as how to determine what is null

[pastel blade]

https://gyazo.com/5c0110acfde6e70bd835d535b62ef30c
my object have a script that can rotate an object X axis rotation and Z axis with 4 button when i rotate X axis to the left or right it work fine Z axis too work fine but when press two button to rotate Z and X at same time it's not rotating as it should be as u can see in the GIF it's like rotating in one angle and not completly rotating in both axis anyone know why this is happening ?
here is my script with the help of gpt

[languid spire]

more likely you need to change the axis settings in the FBX export settings

you are absolutely right

[pastel blade]

where i can find it

[slender nymph]

that was very clearly not in response to you

[pastel blade]

oh sorry didn't notice lol

[gentle vortex]

imagine this: i need to rotate something to face the direction that a character is moving, and i have a velocity vector for said character, though rotation is in quaternions and this is a velocity vector, so how would i do this?

[languid spire]

to add to a quaternion you can do Vector3 * Quaternion

[gentle vortex]

unity tells me i can't multiply vectors and quaternions, that's kind of why im asking the question

[languid spire]

yes you can, I may have it the wong way round, it only works one way

[gentle vortex]

i see

[languid spire]

        Quaternion q = Quaternion.identity;
        Vector3 v3 = transform.up;
        Vector3 vr = q * v3;

[gentle vortex]

i'll be honest i think i confused you and myself with my phrasing

so lets just rephrase it

i have something (specifically a particle system object) that i need to be ALWAYS facing the direction that the player is moving, and after quite a few attempts i have zero idea what i'm supposed to do

[languid spire]

well the direction of the player should be player.transform.forwatd

[bitter walrus]

how can I make it code

transform.Translate(Vector3.right * moveSpeed * 7 * Time.deltaTime);

I can dash through walls

hellpp?

[languid spire]

moving via transform will never respect colliders

[bitter walrus]

so I should move to a rb movement system?

[languid spire]

yes

[bitter walrus]

15 hours before deadline

lol

[mossy crest]

why specify private when fields are private by default

[night adder]

After having created a cinemachine free look cam, and having added my player to the "look at " and follow boxes my character just flies away lol

[slender nymph]

because being explicit shows intent

[slender nymph]

do you perhaps have a collider on your camera that is colliding with your player's collider? because depending on how you handle collisions that would force it to depenetrate, but the camera's collider follows it so it would always be trying to depenetrate

[night adder]

No, and even when the game is not started my player is not moveable

because it always snaps back to a position where i dont want it

[slender nymph]

well then you'll need to actually provide details because i don't intend to play 20 questions just to get some basic information about what may or may not be causing that issue. see #854851968446365696 for what to include when asking for help

[bitter walrus]

Why is this happening

I played with the project settings earlier

Not sure what caused this

Why is my camera changing in size

[wintry quarry]

Check your resolution and zoom settings

[bitter walrus]

Oh shi

Yea

It works

Made it ratio

Not resolution

[languid spire]

@bitter walrus for future reference, please type in full sentences and do not share photos or vidios taken on a phone

[bitter walrus]

yup

np

[tender wharf]

The model is pointing towards z+ but the wheel collider is still in the wrong direction

im dumb

its pointing towards the ground

[bitter walrus]

I could never make a rb based movment have the same feel that I want, is there another way?

[summer stump]

I mean, you definitely COULD. But you can use a CharacterController instead 🤷‍♂️

[languid spire]

not if you want to use physics collisions, no

[summer stump]

There are multiple ways to handle rb based movement
And many ways to handle each of those
You can make it feel any way you want

[cosmic quail]

isnt rigidbody.moveposition on a kinematic rigidbody the same as moving via transform

[summer stump]

No
Similar yes, same no

[wintry quarry]

Set the velocity

[languid spire]

concentrate on using rb.velocity, it will give you the kind of fine control that transform.translate gives you

[bitter walrus]

my character is a fish that constantly rotates towards the cursur, the drag of the velocity makes it move in diffirent direction then it is looking towards

I can set the velocity to reset when I stop moving

[cosmic quail]

yeah i mean same in the sense that if you are moving via transform then you can easily convert your code to non transform without changing much

[bitter walrus]

but I dont stop moving, I just rotate

[languid spire]

then you need to make a new physics material to negate this

[wintry quarry]

By "the drag of the velocity" you mean momentum. If you don't want momentum, you can just override velocity directly.

[bitter walrus]

yes, how tho?

[wintry quarry]

rb.velocity = whateverYouWant;

[bitter walrus]

that is what I do

it still has momentum

[wintry quarry]

you'd have to show your code

because it wouldn't unless you simulated momentum yourself

[bitter walrus]

Vector2 moveDirection = transform.right * moveSpeed;
rig.AddForce(moveDirection, ForceMode2D.Force);

[wintry quarry]

more of the code

[wintry quarry]

Also this is using AddForce

which is not what I said

[bitter walrus]

oh yes

[cosmic quail]

also im still not sure if rigidbody.moveposition on a kinematic rigidbody respects collisions properly or not, heard a lot of conflicting statements on this

[bitter walrus]

how can I change it to how you did it

[wintry quarry]

it respects them in that it will knock other dynamic objects out of the way realistically. It won't stop the object itself.

[wintry quarry]

rb.velocity = moveDirection * moveSpeed;

[cosmic quail]

do walls stop you properly though?

[summer stump]

Not really

[wintry quarry]

no as I said

it will not stop the object itself

kinematic objects are unstoppable forces.

You could solve that with casts

[bitter walrus]

works good, but now its changing my rotation

[wintry quarry]

nope

that would be some other code of yours

or due to crashing into walls

if you want it not to rotate when colliding with things, you would constrain the rotation on the body

[bitter walrus]

I do want to be able to rotate it

but only in code

seems like the RB is rotating it

[wintry quarry]

Let me reiterate

you can always rotate through code, don't worry about that

[wintry quarry]

yes, think about what happens in real life when things collide

they rotate

[pine furnace]

does rb.moveposition require deltatime?

[bitter walrus]

ohhh yeaaa

can I stop that

[rocky canyon]

yea, think someone shoulder checking u

[bitter walrus]

can I stop physics from rotating my character

[wintry quarry]

It doesn't require anything, just a new position. But if you want to use it to move at a regular rate per second - you would use deltaTime generally to calculate the new position, yes

[rocky canyon]

you can constrain the rotations of the rigidbody

[wintry quarry]

I literally have told you how twice now.

[wintry quarry]

Here let me tell you a third time

[pine furnace]

void Update()
{
horiozntal = Input.GetAxisRaw("Horizontal");
vertical = Input.GetAxisRaw("Vertical");
direction = transform.forward * vertical + transform.right * horiozntal;
direction = direction.normalized * walk_speed;
}

private void FixedUpdate()
{
rb.MovePosition(rb.position + direction * Time.deltaTime);
}

so i used it corectly

here

[wintry quarry]

yes

[bitter walrus]

yes, you did, I have the mind capacity of a potato lol

[pine furnace]

whats the difference between rb.position and transform.position

[rocky canyon]

rb controls a rigidbody (uses physics)

setting position is teleporting (translation)

[wintry quarry]

The Rigidbody and Transform positions aren't always synced. Especially when using interpolation and when you're in between physics frames

the Transform position gets interpolated to make things visually smooth.

[pine furnace]

so what should i put in that code

[wintry quarry]

what you have is the most correct

in FixedUpdate it's best to deal solely with the Rigidbody

[rocky canyon]

time.deltaTIme gets converted to fixedDeltaTIme in FixedUpdate correct?

[pine furnace]

oh

your are right

[rocky canyon]

non-issue since it handles it automatically

[stuck palm]

i have this code that uses the handles class, and my game wont build because im using it. how can i fix this?

[slender nymph]

https://unity.huh.how/building/editor-assemblies

[wintry quarry]

Is this code for debugging purposes

or are you expecting it to work in the game?

[stuck palm]

the code is for debugging

[pine furnace]

does add force require time.fixeddeltatime?

[slender nymph]

no

but you should also only be using AddForce with continuous forces inside of FixedUpdate. one-off forces like impulses are fine to do from update (assuming you aren't doing it every frame)

is this movement script good

[rocky canyon]

that all u wanted to ask?

[pine furnace]

yes

it looks kinda scrappy

when i play the game inside unity

[rocky canyon]

its functional

i wouldnt call it good

no offense or anything lol

[pine furnace]

shall i use a ground check, or what could i do to make it better

[rocky canyon]

id lose the _s in ur variables

[rich adder]

or big ass else if chain lol nah you can probably use a collection ?

[rocky canyon]

camelCase is proper way of doing it

[rocky canyon]

like a dictionary/

[rich adder]

yeah or array of Range

[rocky canyon]

sounds good.. do i do that with a forloop?

[rich adder]

yeah or foreach

[rocky canyon]

alright.. that does sound better than a switch

[rich adder]

foreach (Range range in ranges) {
    if (x >= range.minX && x <= range.maxX && y >= range.minY && y <= range.maxY) {
        // found the range
        break;```
ofc idk your usecase so just kinda guessing

[rocky canyon]

imo im at the point where a switch and if-else chains feel both bad to me

[rocky canyon]

rest of the collisions on the other angles work fine. no idea what the issues are with this

[rich adder]

ahh ok

manual buttons?

[rocky canyon]

trying to avoid a clutter-fk of UI elements

[languid spire]

generally if you are thinking about long switch or if else chains then your data design is wrong and there should be arrays/lists in there

[rocky canyon]

yea, been neglecting those.. that the way imma do it now 👍

[rich adder]

been trying to wheen off the switches/else if chains myself

[rocky canyon]

its a process 😄

[rich adder]

ikr its so easy to use but then just becomes a unmaintanable mess sometimes

[rocky canyon]

i just gotta think ahead a little farther

[rare socket]

Does anyone know how to have one script work independantly (track local variables) for multiple prefabs?

I'm currently making a game where various prefabs spawn. I have a script applied to each prefab that adds one to a counter each time a prefab spawns. Once the script reaches four, the prefab deletes itself. I'm unsure why, but the prefab that initially spawns is counting but not the rest. Once its counter finishes, the prefab that spawned second begins its counter. The counter is not a static variable.

The script is below:
https://gdl.space/ekifafomub.cpp

[rocky canyon]

not a clue.. just wanted to say, love ur D.raw class ;D

[rich adder]

D.raw lel

[eternal needle]

I think that's from vertx's plugin

[rocky canyon]

ohh snap! i havent checked his out yet.. only NomNoms

[stuck palm]

lmao its vertx's debugging package,

i thought it was quite clever too

[rocky canyon]

i was gonna ask if it was static.. soo thats 1 thing we can look over

[rocky canyon]

i say b/c i have a D.bug function 😄

meaning his package would break my project 😄

[stuck palm]

😭

maybe different namespaces?

[rocky canyon]

i could do that.

just rename one

[stuck palm]

agh im so close to sorting out this one issue

i'm having to write my own collision detection/solving for this fighting gmae

[rocky canyon]

ur doing ur own collision i see

[stuck palm]

yea

using fixed point numbers

[rocky canyon]

thats outta my expertise homie.

but i wish u luck

[stuck palm]

no worries, thanks anyway

i put it in code advanced but no dice its a desert in there

so i thought i'd check here

as its usually the most active lol

[rocky canyon]

each script instance is creating its own roomCounter

[languid spire]

pretty obvious really.
this first script is finding (roomBehaviourScript.spawningRoom == true
then setting it to false so the rest of the scripts ignore it

[rare socket]

OOOOOOOH

[rocky canyon]

ohh there i missed tha

[rare socket]

I'm officially resigning as a game dev lol

[rocky canyon]

he said pretty obvious.. and i looked over it 😄

[rocky canyon]

me too

[rare socket]

Thank you all so much 🤣

[languid spire]

learn to read the actual code, not what should be there. It is a very hard won talent

[rocky canyon]

yea.. i absolutely agreee.. the more i work w/ Unity the more i see things that arent there..

[rare socket]

Will do 🫡

[rocky canyon]

scratch paper helps..

go thru ur scripts and make a little flow chart.. it helps to break up laser focus.. (and gives u a chance to notice things)

[languid spire]

the biggest problem seems to be that people cannot multi thread their scrips in their heads, multiple instances and the Update loop makes for difficult comprehansion

[rocky canyon]

true, i struggled w/ that making an Enemy script.. (that relayed information to other Enemys)

finally made sense once i realized they needed to know if the enemy they were talkin to was themselves or not

still havent figured out a better way to do that.. besides just loopin thru them and asking if this = me

[languid spire]

very comon problem. How often do we see people assuming what 'other' hit their colliders?

[rocky canyon]

facts.. but what else could "other" possibly be? 😈

[languid spire]

rofl

[rocky canyon]

alright.. soo the coord system needs to know which button to press.. soo.. what i have so far is a list of ranges.. but.. then i grab the index of the true one..
and then i have to do another list and loop to know what function goes with what index...

a dictionary would combine these two i imagine

yet, ive never really worked w/ dictionaries.. 🫣

[languid spire]

no time like the present to learn

[rocky canyon]

im already on it.. expect me to make appearances 😢

[rocky canyon]

here we go! lmao

[errant surge]

Ooooh thanks, can you tell me how i limit the fps? Or how i fix that?

[wintry quarry]

It's not a framerate thing. It's monitor ghosting

https://www.makeuseof.com/what-is-monitor-ghosting-how-do-you-fix-it/

[errant surge]

Thanksss

[rocky canyon]

ohh! yea i see it now

that shoulda been obvious to you outside the game even..

try dragging around a window really fast

[errant surge]

When i do it with a window it doesnt happen

[rocky canyon]

weird..

anyway. my monitor had a setting inside it to fix it

im guessing urs is the same

[errant surge]

Maybe

[rocky canyon]

just took me forever to find it

the menu buttons on monitors are shit

[edgy vine]

So in my game when a person picks up a block and trys to throw it the mouses momentum doesnt get added on. so im wondering how to do that. currently the person can pick up and drag the block but it doesnt actually let them throw it. Right now I just have it say "test" in debug but I am wondering if there is like a mouse.momentum I can take and add that force onto the cube?

using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;
using static UnityEditor.PlayerSettings;

public class Throwable : MonoBehaviour
{
    Vector3 pos;

    private void OnMouseDrag()
    {
        pos = Input.mousePosition;
        transform.position = Camera.main.ScreenToWorldPoint(pos);
        transform.position = new Vector3(transform.position.x, transform.position.y, 0);
    }
    private void OnMouseUp()
    {
        Debug.Log("TEST");
    }
}

[rocky canyon]

you could add a gameobject that tracks the mouse

and test its velocity

[frigid quartz]

How big of a deal is it to run an if statement in my update function?

I want to have a sprite be automatically updated if the sprite variable saved to a scriptable object changes.
I was just going to do:

    void Update()
{
  if (_avatarImage.sprite != _playerDataSO.Avatar) 
  { _avatarImage.sprite = _playerDataSO.Avatar; }
}

Would this be too resource intensive? Would I use an event instead?

[rocky canyon]

u should avoid putting anything in the update loop if u can

[frigid quartz]

Okay, that's what I thought. Thanks

[rocky canyon]

an event would be smarter / and more performant

[fathom bramble]

I am SO confused. My "bullet" prefab keeps bouncing off another prefab when it's supposed to go through it. Now this is likely due to the rigidbody it has. So what I did was make the collider "istrigger" and that fixed it. But now the bullet won't register ANY collision with "Enemy" prefab. ?????? mass confusion

[rocky canyon]

that being said.. 1 if conditional isnt gonna hurt anything

[rocky canyon]

if u were using OnCollision, and then u cahnged to trigger u should go to OnTrigger

Collisions use colliders Trigger uses colliders (marked as triggers)

[frigid quartz]

Nah, I'll probably use this for stuff like name and level too, so I'll just make it an event. Thank you

[rocky canyon]

np, 🍀

[fathom bramble]

so "oncollision" is for rigidbodies

[rocky canyon]

OnCollisionEnter/Exit or any of them wont work for triggers

OnTriggerEnter/Exit/Stay will

[rocky canyon]

its not really related to rigidbody.. b/c u need a rigidbody (atleast on one of the objects) regardless if its OnCollision or OnTrigger

its the collider that makes the difference

[fathom bramble]

why is this a thing?

why do you need a mandatory rigidbody

[rocky canyon]

b/c its the Physics engine thats detecting collisions

needs a Rigidbody for that to happen

[fathom bramble]

if the rigidbody detects it

what do colliders do

[rocky canyon]

Makes the Bounds of the object..

(so the engine knows how big it is) -> where and when it collides

[fathom bramble]

Interesting... Feel like they could have just made it into one component

but okay thanks anyway

[rocky canyon]

that would complicate things.. for example everyones ground object needs a collider.. no point in having a rigidbody on it thats not doing anything

more rigidbodies = more calculations.. even if its not moving

[summer stump]

That would be NOT good.

[fathom bramble]

Why not? Just have a single collider component that just has a flag bool usePhysics; If it's true, the physics engine will act upon collisions, and not otherwise

it's what I do in my own engine though to be fair

it is much smaller

so maybe idk

[bleak kernel]

can anyone tell me which unity version is the best?

2022

2021?

[half egret]

The LTS version

[languid spire]

both are LTS

[half egret]

2022

Latest LTS* is usually your best bet

Depends on what you wanna make

This isn't a code question though

[bleak kernel]

oooooooops

where can i ask it?

[languid spire]

you've had your answer so you don't need to ask it anywhere else

[bleak kernel]

i deleted a msg

[half egret]

The answer still stands

[bleak kernel]

for future

[half egret]

Read #🔎┃find-a-channel and you'll get an idea!

[bleak kernel]

how to find the nearest object to a game object?

[languid spire]

raycast

[edgy vine]

Physics.SphereCast

[half egret]

Physics.OverlapSphere if it has a collider

and is relatively close

[edgy vine]

Id say make a spherecast get all objects near and find the one you want

either tag it or if it has a specific component or so

but thats just me there could be a better way

[bleak kernel]

i cant loop through objects, right?

[summer stump]

And smash everything else physics related into it too?

[half egret]

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

[edgy vine]

I think spherecast would continue through any object

Im not sure tho

[half egret]

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

OverlapSphere returns an array of colliders you can loop through

[bleak kernel]

ohhh

[edgy vine]

Yeah

and to find what object you want id tag the object if you can

then just find all that were hits and find the closest one

[bleak kernel]

oh thank you

[edgy vine]

No problem

I have a throw script for a 2d game and when I try to throw something it does move but it really doesnt move in the direction that i threw it. its a little off and the velocity feels weird

using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEditor;
using UnityEngine;
using UnityEngine.EventSystems;
using static UnityEditor.PlayerSettings;

public class Throwable : MonoBehaviour
{
    Vector3 pos;
    public Rigidbody2D rb;
    Vector2 mouse;
    private void Update()
    {
        mouse = new Vector2(Input.GetAxis("Mouse X") * 1000, Input.GetAxis("Mouse Y") * 1000);
    }

    private void OnMouseDrag()
    {
        pos = Input.mousePosition;
        transform.position = Camera.main.ScreenToWorldPoint(pos);
        transform.position = new Vector3(transform.position.x, transform.position.y, 0);
   
    }
    private void OnMouseUp()
    {
        rb.AddForce(mouse);
    }
}

Any ideas?

[bleak kernel]

change force type?

[edgy vine]

What type should I use?

AddRelativeForce?

[bleak kernel]

wait

let me look

[stuck palm]

@rocky canyon spent like 2 weeks working on this deterministic physics system only to find out photon quantum literally offers the exact same thing for free

[languid spire]

you are mixing transform and rigidbody movement, don't do that

[edgy vine]

Does rigid body have its own type of .GetAxis?

to find the velocity of the rigidbody?

[summer stump]

That is not what they meant

[summer stump]

And no. Just rb.velocity
But that is not anything to do with input

[bleak kernel]

relativ

[edgy vine]

I tried using that but it did not work

[bleak kernel]

oh ok

[edgy vine]

Relative force does make it better

[summer stump]

The transform.position = part is a problem

[bleak kernel]

can you send me a video private?

[edgy vine]

Thats just to pick up the block

[edgy vine]

What is the problem with it?

it has nothing to do with throwing and it works fine

[rocky canyon]

rekt 🪦

[fathom bramble]

My bullet prefab keeps bouncing off objects its not supposed to. Is the best way to handle this to just not use a rigidbody on it?

[rocky canyon]

you can use layers and tell which layers to ignore each other

https://docs.unity3d.com/Manual/LayerBasedCollision.html

[fathom bramble]

I'll check that out but is there something bad about not using a rigidbody here?

[steep rose]

your using rigidbody movement and setting the object position directly thats what he is saying, which is wrong

[willow scroll]

Well, why do you even add force and change the position simultaniously?

[steep rose]

only use one

[edgy vine]

Okay. So instead of setting the objects position directly what should I do? set its rigidbody position instead?

Alright

[rocky canyon]

no, u'd have to change the way u move it

but it wouldn't need a rigidbody.. (but if u removed hte rigidbody it wouldnt detect collisions anymore)

[steep rose]

use rigidbody force to make what you want, dont set the rigidbody position

[summer stump]

It is mixing rigidbody and transform movement and may be causing the problem

Ah, delayed response

[steep rose]

also inputs have nothing to do with transforms

just a side note

[edgy vine]

Yeah I know that

So how would I go about a simple drag to move?

with 2D?

Because setting the transform is the only thing I could think of

Just add force until its on the cursor?

[steep rose]

you can add a force in the direction the mouse is probably

when clicked/hold

[queen adder]

are animation curves useful for the cost of an upgrade

[steep rose]

probably should talk in #💻┃unity-talk or #🏃┃animation

[static bay]

they're useful for defining any change over some range honestly

assuming it's not step-like

[queen adder]

Ooops my mistake wont happen again!

[queen adder]

I figued it out lol I had the whole thing messed up im good thank you

[steep rose]

you're not in trouble just a heads up 😅

[rich adder]

animation curve is coding question

they're talking about this one [SerializeField] private AnimationCurve animCurve

[rocky canyon]

those cause errors for me

not sure y

[rich adder]

what like UI ?

in 2021 i would get Null Refs when I'd fullscreen the Game view after using AnimaionCurve 🥲

glad thats fixed lol

[rocky canyon]

yes editor gui stuff

[rich adder]

ohh thats odd. you're in 2022 ?

[rocky canyon]

.3.5

i just clear em out all the time.. it could be a package conflict

[rich adder]

hella old. Although i would only get those in 2021 havent gotten any in 22

[rocky canyon]

maybe with naughty attribs

but anyway.. yea they're great..

i tend to use them w/ DoTween

sucks that i get annoying errors

[rich adder]

yeah! they're dope. could be conflict with ui drawing

[rocky canyon]

if i keep them collapsed it typically wont happen as much

[rich adder]

try with blank project

or 2022 thats not so old 😛

[rocky canyon]

im unity6 now.. its bound to be fixed :d

these are older projects that are in process of porting

[rich adder]

yaa need to do this myself soon, im waiting for lts 6 though

[plush chasm]

how to check if gameobject has a script attached to it that inherits from monobehaviour

[rocky canyon]

i can never move an entire project in a single chunk anyway.. soo im adding bits and pieces.. and if they're working in this version i just assume they will in LTS

[rich adder]

GetComponent or TryGetComponent

[rocky canyon]

TryGets work good for conditionals

better than comparing a null w/ Get

[plush chasm]

I am not looking for a specific script though will that still work?

[rocky canyon]

it can check if it inherits

[languid spire]

yes, if you use Monobehaviour as the generic argument

[rich adder]

use interfaces

[rocky canyon]

[mint remnant]

Why this error when a is assigned in Foo?

    public void Foo()
    {
        int a = 0;
        Bar(out a);
    }

    public void Bar(out int a)
    {
        print(a); // error Use of unassigned out paramater 'a' 
        a = 1;
    }

[rocky canyon]

unless ur not using it just to run if checks

[rich adder]

because a isn't assigned when you print

[languid spire]

because it's an out varialbe

[rocky canyon]

do u run Foo first?

[rich adder]

a is the resulting out, you pass that after you try print it

[mint remnant]

ah it has no way of knowing if Foo will callit it or something else

[rocky canyon]

you cant use out variables in a print() function?

[languid spire]

not untill you assign something to them, no

that is what out means

[rocky canyon]

lol.. i see now

yea i use outs, for trygets. soo never ran into that issue

[rich adder]

out are goat

and ref too

[languid spire]

out and ref are dangerous af if you dont know what you are doing

[mint remnant]

well method extract created it, and I was just puzzled why it did an assign in the called method is all

[plush chasm]

I used getcomponent<MonoBheaviour>() != null and it found gameobjects without scripts attached to them, possibly because they had other unity components. How do I check if an object has scripts attached ?

i will try to lerp

[half egret]

Using something like DOTWeen can simplify your LERP, but you should learn how to do it the "proper" way first

[rich adder]

yes

[mint remnant]

and just because I like to say it, after you learn Lerp go lookup Slerp

[rocky canyon]

DoTween

just dont X = Lerp(X, Y); and ur fine

altho i still do this in prototype code 🫣

[long jacinth]

bruh thats the drink from fortnite

[long jacinth]

ok so i use a tutorial

here's a fun one to try color = Color.Lerp(Color.white, Color.black, Mathf.PingPong(Time.time / 3, 1f));

[long jacinth]

what does that do

smoothly changes colors?

im in a game jam im getting too caried away

but i should try that

later

maybe i could find it useful

[languid spire]

why the ++j ?

[worthy merlin]

Its a recursive backtracking program I am following. I was following it and brainlessly kept that. I feel like it does the same thing as j++ doesn't it?

[languid spire]

in that context, not at all

[half egret]

It's slightly different

[worthy merlin]

oh?

[mint remnant]

in a for loop at that point it does the same thing

[languid spire]

no it does not, increment before rather than increment after

[worthy merlin]

Copilot has saved 3 MC villages from burning this day forth 🥹

also is there an asset or something that makes it so when i save vs and enter unity it doesnt take 10 seconds

i cant explain how unsatisfying that is

this is good to know, thank you!

[half egret]

For entering play mode you can disable reload domain/reload scene
https://docs.unity3d.com/Manual/ConfigurableEnterPlayMode.html

[long jacinth]

is it a bad thing if i disable it?

[languid spire]

please don't tell him that, we are gonna get lots of problems because he 'forgot' to recompile

[half egret]

@long jacinth You'll get issues if you forget about mechanics that need their scripting state reset... But upon further consideration Steve is probably right. If you're this early on in learning, I'd deal with the "long reload" times for the time being. Just know, down the line, when you become more experienced it's something you can control. But it comes with caveats.

So yeah, don't change that.

[long jacinth]

ok

[half egret]

I often forget this is the code beginner channel..

[languid spire]

in a lot more ways than just code, lol

[fathom bramble]

Why is only this object destroyed when I reset the scene? (load it again)

I get an error saying I'm trying to access it when I reload the scene

but then why does only it throw that error

it's just an empty gameobject

[languid spire]

because it is not DDOL

[half egret]

DontDestroyOnLoad

[fathom bramble]

What caused it to be that

I didn't change it

[half egret]

Everything is NOT DDOL by default

[languid spire]

that's the point, you probaly need to

[fathom bramble]

but then why did everything else load in just fine?

[half egret]

How are you trying to reference it

Does it just dissapear from the scene?

[languid spire]

Hodo mentioned DontDestroyOnLoad, I said DDOL, did you bother to go and see what that means?

[fathom bramble]

it subscribes to certain messages

[cedar mirage]

I have been making this basic level platform with this player. But for this whole project I have been using this little character Player (black) game object.

so all of my diff gameobject components have this gameobject dropped into them.

Is it possible to replace this gameobject with the White one in my assets?

without having to redo any settings and pasting into components?

thanks!

[half egret]

[oak tapir]

im making a vr game but im in my vr and when i click play my screen and the vr just turns gray. what do i do

[fathom bramble]

I understand what it means

I'm trying to find out why only that gameobject

is having this issue

[languid spire]

because you are trying to reference it cross scene

[fathom bramble]

I'm doing this

I'm reloading the current scene

but when I do, every other game object loads in

except that one

[rich adder]

#854851968446365696 how to post , also #🥽┃virtual-reality

[half egret]

You'll likely have the same issue if you try referencing any other object on scene reload

A new instance is created on scene load, and the old one you were referencing doesn't exist anymore

This is my theory, but I don't have the full scope of the problem and your setup

[fathom bramble]

it doesn't. For example, when the scene reloads

the map object exists, the spawn points exist

they can be used

only the UIManager is gone

[half egret]

How do you reference UI manager

Is it just a direct reference?

[fathom bramble]

No

it subscribes to a message

and acts on it

See it's suchhh a weird bug

[half egret]

Does the UIManager exist in the scene hierarchy on reload

[languid spire]

and do you unsubscribe before the scene reload?

[fathom bramble]

like unsub from the message?

I don't..should I?

[languid spire]

of course

[half egret]

Otherwise you're leaving a lot of event listeners open for no reason

[fathom bramble]

but doesn't the scene reload

destroy it anyway?

[languid spire]

no

[fathom bramble]

wait sorry but isn't that the entire error to begin with? That UIManager is destroyed upon scene reload?

Why would it still be subscribed

[languid spire]

the problem is the subscription is still active but the object that subscribed to it no longer exists

subscriptions to events do not automatically get removed, it is always a manual process

[cedar mirage]

Is there a simple way of knowing what the exact y-axis coordinate is for the bottom of this platform?

or for a specific point on the grid in general?

[languid spire]

yes

[edgy vine]

Create a cube and put it where you want then look in the transform?

[cedar mirage]

yeah my bad i know i can do this

is it like the simplest way though?

like is there a built in thing where i just click a spot

[edgy vine]

Not that I know of

[languid spire]

simple math
transform.position - (height / 2f)

[edgy vine]

Just spawn a cube or something and put it on the position you want and write down the transform

[fathom bramble]

You were right!! I implemented the unsubscribe method in the messagebus and it worked! Thanks for your patience sir ^-^

[cedar mirage]

the f being?

or is that just a label for that constant

[languid spire]

doing float math

[cedar mirage]

ah i see thanks

also another question, is it generally better practice to avoid scaling objects when trying to change the size? and instead editing the actual size of the object

or does it not matter at all

[languid spire]

yes, scaling objects leads to all kinds of shit

[rocky canyon]

scale things as children

keep ur main obj 1:1:1

esp if its dealing w/ physics in anyway

[cedar mirage]

bet

[edgy vine]

Womp Womp

lmao

[cedar mirage]

facts

[edgy vine]

Hes tired

[cedar mirage]

i drew this dude in adobe in like 1 minute cuz i didnt wanna use a regular square

lmaoo

question though, im using rigidbody2d for the player's movement n physics, but I didnt want the player falling over like that, so I froze the Z in the rigidbody constraints

and now it doesnt fall over anymore

is that the best way to achieve that?

or is that like some brute force way

[spiral oak]

yeah
at least the simplest

[edgy vine]

You could find a 2D Player movement script that does it all for you online easy

If you dont want to go through the hassel of doing everything

but if not then yeah thats the way to do it

[cedar mirage]

i see

ok another question, i'm seeing different ways to avoid a gameobject from getting stuck on edges like this, whats the best practice to just have the player slip off

[tardy needle]

How can I display a score and increment it when I kill an enemy. I am having some null reference problems and dont know exactly why

[languid spire]

look at the error and the stack trace it will tell you exactly why

[cedar mirage]

[tardy needle]

Does the script of the text should be in the canvas or the text

[queen adder]

What would be the the most optimal way to use data from another scene

[sacred horizon]

when i try to export my game i get a error

[languid spire]

DDOL

[queen adder]

Okay good thats what im using

[tardy needle]

Thanks this helped

[cedar mirage]

no prob bro

[cedar mirage]

any1?

[rich adder]

best way is not applying force/velocity that direction is blocked

usally cast

[cedar mirage]

well this is how my player movement is set up right now

Move = Input.GetAxis("Horizontal"); // gets input of users keyboard

        rb.velocity = new Vector2(speed * Move, rb.velocity.y);

        if (Input.GetButtonDown("Jump") && !isJumping) {
            rb.AddForce(new Vector2(rb.velocity.x, jumpStrength));
        }

i dont see how id not add force in that direction when i need to be adding force in that direction so the player can move left and right

Also I added a physics material 2d and reduced the friction and it seemed to do the job

[rich adder]

yeah no friction material works ok but its not the best

I combine with just using a cast

[rich adder]

you just dont apply the speed if collision is detected in that direction, no big deal with casts

[cedar mirage]

i see ty

why cant i find the sizing section?

im trying to avoid using scale to make this square bigger but i dont see size anywhere

prolly a dumb mistake im doing lol

[rich adder]

you have to make a child object and scale that just for the graphics

use the size properties on the collider component on root

[cedar mirage]

i know i can size up/down the collider but that wouldnt make the square itself bigger

[rich adder]

the collider Is the square

what you're referring to is the graphics too

[cedar mirage]

so i cant size without adding a child object?

[sand heath]

if you want the sprite to be bigger you either need to change the reference resolution or change the scale

[rich adder]

copy and paste that sprite renderer in child object, resize however big you want then fix collider on root

[cedar mirage]

sorry im just a bit confused

like u mean to copy and paste the sprite renderer that is in my root into the child?

btw I just created a blank gameobject and made it the child of my original red square which is Death

[long jacinth]

everything was working fine until suddenly this popped up

[rich adder]

is this just for a trigger?

[long jacinth]

18 errors that follow something like this

[rich adder]

and yes

[rich adder]

duplicated class

[long jacinth]

why is this happening?

[rich adder]

you made a duplicate somewhere

[long jacinth]

i didnt touch vscode i just saved all files then closed

oh

thanks

[cedar mirage]

ok sorry i think i figured out how to do what you meant, however, I'm only able to resize it to be larger, when i try to make it smaller it doesnt work

[rich adder]

wdym "doesnt work"

[cedar mirage]

like as i adjust the scale to be greater the square's size increases ofc.

when i pull the scale to make it smaller it just stays at it's original size

this is after i pull the scale to make it smaller, the little square outline is whats changing

[rich adder]

wait did not delete the sprite renderer on the root

[cedar mirage]

ohhh

no i didnt

lemme try

ok it works now thank you!

another problem though...

im trying to readjust the box collider to fix this new size. but it isnt aligned correctly to the actual square object

i thought this would have to do with the root's transform scale size, but i set it to 1:1:1 and it is still unaligned

[rich adder]

first make sure you reset the child position

it should be in the middle, then make sure the collider Center has no offset

[cedar mirage]

ohhhh ok perfect yeah that fixed it. and yeah it had no offset

ok so i kinda have a logic question

so based off all this, im assuming it is simply better practice when working with sizing and moving objects such as this, to always have a child object of the sprite to do all the sizing?

then if i want to move the object's position, that should be done in the root?

because why wouldn't I want to just change the scale of it straigt up in the root?

[rich adder]

scale usually messes with a lot of things including the physics, and rotations (if you ever want to resize something non-uniform)

it doesnt affect movement so much usually

[cedar mirage]

so its best to scale in the child because of that?

[rich adder]

since its only for visuals yea

if your gameobject scale is 1,1,1 you have a box collider scale 1,1,1 size you know for a fact its a 1 meter box

its more accurate for the physics too

[cedar mirage]

but what do u mean by box collider scale 1,1,1

[rich adder]

if you make something too big or too small with scale you will notice its "off"

[cedar mirage]

when it just has size

x & y

[rich adder]

yea size of the collider

but size is always * scale

so anything * 1 is 1

[cedar mirage]

ah okay

ok but im just realizing this

i didnt even use the sprite renderer in the child lol

like i didnt change anything in it

is the only point of adding that so the child has access to the visual of the object?

[rich adder]

not sure what you mean

access the visual?

[cedar mirage]

like you said i needed to copy and paste the sprite renderer that i originally had in the root

to the child right

[rich adder]

oh yeah , I meant more Cut and Paste but yea

[cedar mirage]

which i did

yea

so what is the actual reason

i feel like i get it but also dont

even though i do understand what a sprite renderer is

[rich adder]

well I originally thought this was some type of character

so can scale the red any size you want without affecting the original parent

[cedar mirage]

ohh nah its just something that my player will run into

and die by touching

my bad

[rich adder]

thats why I asked after if its only meant as trigger you dont really need to sepearate it and just scale it since it wont have rigidbody

I still do it for other 3D objects though

[cedar mirage]

ahhh i see my bad yes it is a trigger in that case idk why i did thumbs down

[rich adder]

like if I have a sword, the original parent is 1,1,1 always but child has mesh which is scaled in gameobject scale

[cedar mirage]

ah okay

so usually though i should have a child parent to scale it if im using rigidbody

like physics

[rich adder]

ideally yeah since graphics dont really affect the functionality

[cedar mirage]

makes sense

[rich adder]

if you start scaling a rigidbody too much/little for example you get very inaccurate colliisions

[cedar mirage]

so why is it generally said though to avoid using scale? do they mean if ur using a rigidbody?

and that it's fine to scale inside of the child

[rich adder]

aside from physics scale can mess with your parenting objects

[cedar mirage]

i see

[rich adder]

if you parent something to bigger scale it all gets multiplied too

[cedar mirage]

understood

also sry i gtg rn

[rich adder]

then you have non-uniform scaling which will cause skewing/distortion when rotating

[cedar mirage]

but i appreciate all the help

[ivory breach]

I'm trying to make my main model's mesh as well as an array of other assigned meshes (in this case, all of the object's child meshes) flash white. It works as intended, but my fps drops significantly every time the flash happens. Can anyone explain what needs work to solve the issue?
https://gdl.space/arelequyip.cpp

Strangely, the freezes are only apparent in the editor's game window if it's in a small size

[eternal needle]

look at the profiler to see specifically where your issues are, i suspect its probably just the double for loop of assigning materials to an array then assigning to the renderer.
Though I truly dont see why that double for loop is even needed, it doesnt seem like j relies on i or anything. And the GetComponent would just be returning the same value here anyways

[ivory breach]

Thanks, I'll try to investigate that part of my code

Update: Looks like you were right. The code worked the same even without the "j" loop, and I don't see the frame rate drops anymore

@eternal needle Thanks for your help

[eternal needle]

You should still cache that GetComponent call, but hopefully you understand why it works rather than just doing it cause I said

[strong wren]

hi

[silver forge]

im new to unity and c#, and im trying to set up a laser for a game im making however its sorta broken and im not sure whats happening with it, the laser’s raycast midpoint is somehow set where the laser starts instead of the midpoint of the ray. i've done a ton of debugging and just cant seem to find the problem

oh ok

https://gdl.space/hejesuqofi.cpp

[strong wren]

https://hastebin.com/share/pelotasahu.csharp why isnt this code working?

oh wait leme be more detailed

the code is working but there is a basic if statement that if it doenst work the Rounds wont work it is located in the "Waves" method

        {
            Debug.Log("Check");
            WaveOn = false;
            WaveFinished = true;
            WaveCompleted = true;
        }``` this is the snippet of code that isnt rlly working

and im confused asf

Line 57 - 63 that is the location of the snippet

https://hastebin.com/share/memafukuqe.csharp this is the code that contains the variable kill

it isnt important at all as it is pretty basic but yeah

[fair steeple]

Hey, what's a good way to make camera changes a-la-silent hill? I have a bunch of box colliders with a script that turns all the cameras off except for one, but it's a bit cumbersome to edit and a bit buggy too. I have a navmesh where the player moves with a point and click mechanic. Is there something I can do with navmeshs, or a terrain to trigger the camera change?

[sand heath]

you haven't said what the problem is yet

[strong wren]

the if statement isnt working

[sand heath]

use cinemachine cameras

and then when you enter a trigger, swap the active camera

[strong wren]

its supposed to be true once the ChildSpawned Variable is as big as the S.Kills Varialbe correct/

[sand heath]

then debug and see what the if statement evaluates to

[fair steeple]

I'll look into that, but I was looking for something to replace the triggers

[strong wren]

i did some debugging but the if statement is never true

[sand heath]

why exactly?

[sand heath]

right so why is it never true

[fair steeple]

Not a fan of working with them, I want to see if there's an alternative that makes it easier

[strong wren]

thats the thing i dont know its supposed to be true when 2 variables are the same size, and they are but its still false

[sand heath]

you could make your own colliders

[fair steeple]

Like meshes?

[sand heath]

no, I mean coding your own physics to detect when your player enters the trigger

[fair steeple]

I only ever used the torus and box ones

Ah

Seems simple enough

[strong wren]

its not that hard to do it btw

[silver forge]

https://gdl.space/hejesuqofi.cpp could i have help with this please?

[fair steeple]

Thanks, I'll get to it

[sand heath]

debug and hover over the values and make sure they're equal

[sand heath]

is the ray hitting the inside of the collider

[silver forge]

nope, its hitting the square infront of it

[tardy needle]

Is there an easy way to assure that a bullet hits 1 enemies and not multiple enemies at the same time?

[strong wren]

yes

if it collides with an enemy delete the gameobject

[sand heath]

they're already doing that most likely

[tardy needle]

Thats what I do but it won't work

[sand heath]

they probably mean when a bullet hits multiple at the same time

on the same frame

[tardy needle]

I even added a boolean to make only 1 enemy hit

[strong wren]

so i found smth interesting

[tardy needle]

exactly

[sand heath]

I was going to suggest that

[tardy needle]

This is the code

[sand heath]

I can't fully read the code

[strong wren]

dude i fucking hate 60% keyboards

every time i want to use <> i have to type them in discord then copy and paste them into visual studios

[sand heath]

I meant because it's not in English, you need to translate it if you post it here

[tardy needle]

Oh, my bad

[strong wren]

u have to be the only one who programms in another language tbh

[tardy needle]

Well

Im the only one reading the code when developing

[sand heath]

I think Asia usually programs not in English internally

[tardy needle]

Helps me

But not others if I ask for help as I can see

[sand heath]

but in this case you have to post in English because of the rules and also because i can't read it lol

[tardy needle]

Didn't know that my bad

public class Bullet : MonoBehaviour
{
    Rigidbody2D _rb;
    float _bulletSpeed = 34f;
    float _maxLifeTime = 1f;
    float _bulletDamage = 1f;
    bool _hitting = false;

    // Start is called before the first frame update
    void Start()
    {
        _rb = GetComponent<Rigidbody2D>();
        _rb.velocity = transform.up * _bulletSpeed;
        Destroy(gameObject, _maxLifeTime);
    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.tag == "Enemy" && !_hitting)
        {
            _hitting = true;
            Destroy(gameObject);
            Enemy enemy = collision.gameObject.GetComponent<Enemy>();
            if (enemy != null)
            {
                enemy.receiveDmg(_bulletDamage);
            }
        }
    }

    private void OnTriggerExit2D(Collider2D collision)
    {
        if (collision.gameObject.tag == "Enemy" && _hitting)
        {
            _hitting = false;
        }
    }
}

Dont know if there is a way to paste code with the colors that are in the IDE

[strong wren]

there is

using external websites

i think some of these do that but its not important

[mossy crest]

In the UI Builder, my UI looks like this

Good!

In the actual game, my UI looks like this!

Bad!

[strong wren]

i think u need to do some layering?

i dont know

[mossy crest]

1. Why is it doing this
2. Why is there a preview that doesn't accurately preview

[mossy crest]

wdym

[strong wren]

you ever used anything related to editing?

like blender

photoshop

anything

you know how there is layers right?

unity does that to

wait

[mossy crest]

i've used photoshop yes

[strong wren]

you see this tree?

[mossy crest]

the problem isn't the order of drawing, it's that the character and the bar are the wrong size and in the wrong position

[strong wren]

behind this tree there is a red tree but you dont see it as i put the green one above the red one in the hierarchy

i have no clue i tried to help, but as usal i fail, good luck with ur issue tho

[mossy crest]

you can see all the elements, they're just in the wrong place and too small

[eternal needle]

This is a coding channel. #🔎┃find-a-channel

[mossy crest]

ty

[mossy crest]

oh my b

[strong wren]

still could be a coding issue

[sand heath]

might be your canvas reference resolution

[eternal needle]

It really isnt.

[sand heath]

also #🧰┃ui-toolkit

[strong wren]

could be some of theyre code is fucked up therefor making the ui display wierd ass stuff

[sand heath]

xml isn't really code

[strong wren]

technically it is 🤓

[sand heath]

ok

[strong wren]

it is bassically 1s and 0s

🤓

im such a fucking loser

[silver forge]

i have not found a solution yet

[eternal needle]

So pedantic that it's just wrong. But if you wish to give them code solutions then it's not like I care to stop you

[sand heath]

maybe #⚛️┃physics would be more help

it seems more like a physics problem than a code logic problem

[strong wren]

this is a scam

it looks real but hover over the link

DO NOT CLICK IT THO

text the speech taught me well

still not deleted

yaaay 🎊

[silver forge]

that channel is kind of inactive lol

[strong wren]

welcome to unitys discord server

only active channels are the scriping ones

[rare socket]

Wait, I have a question about unity's animator, should I post that in animation rather than here?

[strong wren]

depends
