[silver girder]

this is a play sound script
It Doesnt work when the handball falls
doesnt play sound on collision

[rare basin]

then debug it

to see what exactly is failing and why

[fossil gulch]

so I wanted to check whether there was a grid point in the direction that the player tries to move, but I've been unable to figure out how to do so

[silver girder]

i dont understand what is debugging

[rare basin]

do you know what's google?

you can look it up "debugging in unity"

[silver girder]

i just did

[rare basin]

then read about it

[polar acorn]

Debug Log should literally have been the first line of code you ever wrote. If you don't know what that is, then you're progressing too fast and you should fall back to the basics, like the ones pinned here or on !learn

[tidal kiln]

i think the issue might be with CanMove / FindClosestTarget

[fossil gulch]

just got it working

[merry spade]

Hi @tidal kiln its me again with the tetris problem. I used the fix u suggested and It works perfectly thank you again!

[tidal kiln]

oh what was it

[fossil gulch]

well I was snapping the player back to the last grid point if they tried to move off of the grid

and it was doing that infinitely

[tidal kiln]

nice man

[fossil gulch]

so I added a check

[tidal kiln]

yea thats what i thought it was

[fossil gulch]

lemme show you rq

this also means I can save on colliders as all I have to pay attention to is the grid points

https://gyazo.com/d45b7adfa2d8bbca20e8a548ed629b7b

[tidal kiln]

nice looks great

[fossil gulch]

now I can stop caring about all that and just go to a basic test map 😂

for enemies, etc

[tidal kiln]

lets gooo

[fossil gulch]

also thinking of adding mod support, done it in past projects and I think it'd be fun. Thanks a lot for your help!

[tidal kiln]

no problem

[fossil gulch]

@timber tide (Sorry for ping but also just wanted to thank you for helping me out a few hours ago)

[tidal kiln]

btw i dont see the player stopping but i think might be an issue with resettingn the animator

[fossil gulch]

what do you mean with stopping?

[tidal kiln]

this

[fossil gulch]

oh, that's happening because a targetPosition is set upon making input, which is reached using the transform.position = Vector3.MoveTowards(transform.position, targetPos, baseMoveSpeed * Time.deltaTime); line in the MoveRoutine, and that makes it so the player stops

[blissful spindle]

Hi, I ran into a little confusing problem for me, the thing is, that I am instantiating an empty object(floating DMGnumber) which works pretty much perfectly, but when it instantiates it turns by 180 degrees and I have no idea why can someone pls help me?

if something isnt clear juts ask me and I will provide everything you need 🙂

[fossil gulch]

also why I wanted to stop the MoveRoutine from finishing in the first place, or wanted to alter the targetPos to 2 points ahead if the button was being held down, but I was unable to do that

if that makes sense

[tidal kiln]

did you fix it

[fossil gulch]

I did not

but your script found a work around

I'll revisit the issue if it pisses me off in the future but this is fine

[timber tide]

you are using lookat for rotation there so I'd look into that

[tidal kiln]

ok cool

[blissful spindle]

ye, I am little bit confused why would that be the problem, and to be fair I have no idea how to resolve this but ye you are right.

[timber tide]

shouldnt be instantiating a new canvas per text either

one canvas, instantiate the string onto that

[blissful spindle]

will that be a problem in the future?

[timber tide]

it's more that canvas is actually pretty terrible for floating combat text but that's something you can probably look into later

but one canvas per text isn't a good solution for right now

[blissful spindle]

I see... well I guess now I need to see why is it turnin back on my camera first then I will look into those canvases then.

[blissful spindle]

ok, also can you please give me an explanation on why is it a bad for floating combat text? I am curious

[timber tide]

each canvas is an additional draw call for one

for performance comparisons, usually mobile games try to stick around 100 drawcalls

now for a single canvas solution, it does a full redraw everytime something moves on that canvas

[blissful spindle]

will it be hard to make it work with one canvas with how it works now (what I mean is: do I need to rewrite the whole code?)

[timber tide]

I'm just saying there's better solutions out there, but until you run into performance problems it's nothing to worry about.

but you'd see the implications quicker if you stick to a one canvas one text solution

[wind raptor]

I'm struggling to understand how sprites scale and how they correspond to scene coordinates. I have a png which is 225x225 pixels. I put it on a sprite renderer, and it is tiny in the scene. I know I can scale it up, but I'm just trying to wrap my head around how the units convert/relate to one another.

[wintry quarry]

In the sprite import settings there is a Pixels Per Unit setting

That's what determines the size, along with the sprite resolution of course

so if you set PPU to 225, your 225x225 sprite will be 1x1

[sleek orchid]

Ey! I don't know if this is the proper place. However, any ideas of starter games just to get Unity's grasp. I've made a crappy version of Flappy Bird so far. I am mainly looking for 2D projects

[wintry quarry]

if PPU is 100, it will be 2.25 x 2.25

[wind raptor]

ah, k. I thought the units corresponded to pixels

1 to 1

[wintry quarry]

no the conversion factor is the PPU setting

If you set that to 1, it will be 1 to 1

[edgy needle]

hello, so i have school work to do, im making game like jetpack joyride, i made almost everything but 2 things are killing me so bad, first being map generation, i understand how it works but even chat gpt cant help me, can someone help me write chunk map gen?

[summer stump]

even chat gpt cant help me

Yeah. Of course it can't

[edgy needle]

i even bought gpt 4

[summer stump]

Chat gpt is a spam machine that doesn't understand anything and lies to you while providing garbage

Even 4

[edgy needle]

ik i hate it but i tried everything

[blissful spindle]

Ok then, well thank you for helping me. 👍

[summer stump]

Impossible to try everything. Explain the things you HAVE tried though

[edgy needle]

i cant fix it for month now, i coded coin spawn, score, everything, even animation stuff on ground n shi, but map gen is js trolling atp

[edgy needle]

writing it myself, googling, chatgpting n shi

[summer stump]

That explains nothing

What specific methods did you try

[polar acorn]

Well, first off, you're going to need to decide what "map gen" even is. That's a vague term. What are you trying to do

[cosmic quail]

did u find this by googling https://www.youtube.com/watch?app=desktop&v=ofZtyysHp1s maybe that has map gen in it

[edgy needle]

there are always gaps and it wont spawn

[edgy needle]

yeah, no few background scrolling like i want

[summer stump]

#💻┃code-beginner message

[edgy needle]

i have bg 1, 2 and 3, and player is static, i first tried when x seconds passed, based on movement, remove bg1 and when is he on bg2, make next 2 random bgs in front, when time passes, remove bg2 and assign 2 random etcc

[timber tide]

Some other ideas is to just use 3D text (text in world space) and use lookat with those

[cosmic quail]

can u do this but make it for 2d https://www.youtube.com/playlist?list=PL0WgRP7BtOez8O7UAQiW0qAp-XfKZXA9W

[edgy needle]

tried

already

[blissful spindle]

oh, you mean this?

[timber tide]

not using the canvas

3D -> text

[edgy needle]

my player is also static, like flappy bird does

[blissful spindle]

oh. I see I tought you ment just the world space ye I gort you now sorry 😄

[polar acorn]

Okay, that seems reasonable. Seems like all you need to do is find a way to know when you've "left" a background, and how to spawn a background from a queue. What is the part you don't know how to do

[edgy needle]

everything i deleted everything now, it was supposed to be my friends part but he kinda did sum and teacher gave it to me, even tho im just a designer, and i struggle one month to fix it

[polar acorn]

If you need to know "everything" then you're never going to reach it. Start thinking about what specific things you need to do, and do them one at a time

[edgy needle]

i just want exact copy of jetpack joyrides map generation to work, and get grade i already did 90% of the job

[polar acorn]

Learning how to break a problem into smaller ones is basically the single most important skill you will ever have in any endeavor for the rest of your life. So, start on it. Define what, specifically, you need to do, and do one thing at a time until you run out of things to do

[edgy needle]

i did just that, it just dont work bro nor do i need it anytime in life, even teacher knows that so he told me that i can copy it, im a sound designer and artist i really dont need coding

[polar acorn]

"it just dont work bro" is not an answer

What, specifically, isn't working, and what is the code that led to that

[sleek orchid]

Anyone can give me a hand?

[ornate lynx]

i'm sorry to bother but can anyone help me in #🖼️┃2d-tools

[queen adder]

how to stop my rigidbody character from sticking to walls when i move into them?

[edgy needle]

is there any channel i can pay a person to write me whole bg scroll script?

[ivory bobcat]

Probably add a physics material with no friction

[polar acorn]

no

[queen adder]

nope

[rich adder]

prevent movement with raycasts if blocked or try the physics material no friction

[queen adder]

I want to be able to walk on top of them, I am making a platformer

they mean on the character's collider

[sleek orchid]

Cheers! That was of great help ❤️

[queen adder]

but I will still slip right?

[rich adder]

are you moving with AddForce or Velocity

[queen adder]

new Vector2(x,y)

idk what that is called

[rich adder]

that answered neither

[queen adder]

wdym

[blissful spindle]

its better to sned the whole code as printscreen if you can

[queen adder]

player.velocity = new vector2

thats my script

[rich adder]

so velocity then

[edgy needle]

ty

[edgy needle]

ahahah i js hate coding man thats it

[chilly moat]

How does one play an audio clip with a random starting time? Setting audiosource.time to a random value between 0 and clip.length does not work, it throws an error 😦

[rich adder]

what is the error?

[blissful spindle]

understood, and noted 📔 🖊️

[ivory bobcat]

Maybe tell us what the error is?

[bitter carbon]

for some reason this says game object with animator inactive even though i instantiate it the line before, could anyone help me please
Image

[polar acorn]

What error

[rich adder]

put the no friction physics material on the collider then

[polar acorn]

You're accessing the prefab

not the thing you just spawned

[summer stump]

Again, you are accessing the PREFAB (redGuy)
I just told you that on the other channel

[queen adder]

friction set to 0 does nothing, it slips if I walk on the object

[bitter carbon]

sorry i was about to say that

[queen adder]

why does my character even stick to the wall in the first place?

[summer stump]

thing = Instantiate(prefab)
thing.GetComponent

[rich adder]

because thats how real physics work

[queen adder]

I get it

[rich adder]

if you kept applying Velocity towards a wall why should it slide down

[bitter carbon]

ok thanks

[queen adder]

in other platformers you cant stick to walls and still walk on same surfaces fine

[rich adder]

the best solution is the one i mentioned imo

normally a Physics cast is done to check the direction of movement if its blocked or not

if its blocked you prevent movement in that direction

[ivory bobcat]

The rigid body component adds rigid body physics to your game object.

[queen adder]

yes I have raycast for isGrounded

have to figure out how to do the one for walls then

[rich adder]

..ok so the concept is similiar

instead of checking solid down, check in front of you / behind n whatever

[queen adder]

and if touching, x movementSpeed = 0?

[rich adder]

raycasts can be used as "Sensors"

[queen adder]

is that how it works in other games like supermario?

[rich adder]

probably not

there is never one way to do something

some games the walls aren't even colliders, they are just 1s and 0s on a grid

[queen adder]

I think I could make 2 box colliders for object and put different friction values on the top (floor) and its wall

what do you think about that?

[bitter carbon]

seems to work thank you
also i have another question, i need to add a animation controlller but the wya i tried did not work

[rich adder]

i think you should try the physics material how you had it before

just increase the players drag

[polar acorn]

Do you have a component named Controller

[bitter carbon]

no but unity has one built in, doesnt it

[queen adder]

very weird there arent any tutorials on yt about it

[polar acorn]

No

[rich adder]

thats a property/field of the Animator component

[polar acorn]

That's an Animator

[willow scroll]

Well, the answer should be why the Animator should have a Controller component

[willow scroll]

This's Animator's property, so you access it via Animator.controller

[polar acorn]

You can call GetComponent on a component just fine, it checks the object the component is on

[willow scroll]

Oh, exactly

[bitter carbon]

oh ok thanks

[blissful spindle]

can someon help me to afjust this line of code to face this object away from my camer instead towards? transform.LookAt(Camera.main.transform, Vector2.up);

[rich adder]

- nvm that 😅

[polar acorn]

Can't negate an object for LookAt, it's not like LookRotation

[blissful spindle]

I tried it like this -transform.LookAt(Camera.main.transform, Vector2.up); and like this transform.LookAt(-Camera.main.transform, Vector2.up); neither worked

[fossil gulch]

Does anyone know why the movement is so jittery?
https://gyazo.com/f3008793a9a9d010e9f8a4d1684089d9

using UnityEngine;

public class FreeMovement : MonoBehaviour
{
    public float speed = 5f; 
    public float rotationSpeed = 10f; 
    public Animator animator; 
    public string movementParam = "forward"; 

    Rigidbody rb; 

    void Start()
    {
        rb = GetComponent<Rigidbody>();
        rb.useGravity = false;
    }

    void FixedUpdate()
    {
        
        float horizontal = Input.GetAxisRaw("Horizontal");
        float vertical = Input.GetAxisRaw("Vertical");

        
        Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;

       
        rb.velocity = direction * speed;

        
        if (direction != Vector3.zero)
        {
            Quaternion targetRotation = Quaternion.LookRotation(direction);
            transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * rotationSpeed);
        }

        
        animator.SetFloat(movementParam, direction.magnitude);
    }
}

[rich adder]

Ah yeah just realized its LookAt

ops

[fossil gulch]

the camera movement is very smooth but the player is jittering

[rich adder]

yeah nvm that lol forgot LookAt does its own thing

[polar acorn]

What you want to do in that case is get the direction between the two objects by subtracting them and then using LookRotation to look in that direction times -1

https://docs.unity3d.com/ScriptReference/Quaternion.LookRotation.html

[fossil gulch]

I know that this often happens with bad parenting stuff but this is what my hierarchy looks like

[blissful spindle]

ye, its ok,np 😄

[fossil gulch]

the movement script is on the Child Player and the Parent player is just an empty gameobject

[blissful spindle]

thnaks, I ll look into it, much appreciated

[bitter carbon]

makes me do runtimecontroler instead. idrk what that means so i tried to make it work anyway but it doesnt like it

[polar acorn]

runtimeAnimatorController is not a string

So why are you trying to set it to one

[rich adder]

wtf is going on here lol

[bitter carbon]

im trying to set its value to it

[rich adder]

are you just guessing stuff?

don't

[summer stump]

Did you look up the docs?

[polar acorn]

How are you intending to set an animator controller to a string of text

[bitter carbon]

idrk

like there is one called New Animatoe Controller

so i thought it would assign it

[summer stump]

Stop. First of all, did you look up the docs?

[bitter carbon]

no, i can never find what im lookjing for on there

[summer stump]

Well you can for this, and it should always be your first stop

[rich adder]

its literally written by the people who made the components you are using

you just have to actually learn how to read the documentation

[summer stump]

The manual may be easier for you? Here
https://docs.unity3d.com/Manual/class-Animator.html

[tidal kiln]

ive never done it like this before but maybe its an issue with setting the velocity every frame (just guessing)

[fossil gulch]

nah it was the rigidbody not being set to interpolate and continuous

[tidal kiln]

oh nice

[rich adder]

input capturing should go in Update btw

[fossil gulch]

it is

is it not?

[tidal kiln]

you have it in fixedupdate

[fossil gulch]

oh lmao

I changed it

was already changed in my script so that's why I was confused

[bitter carbon]

can anyone telll me what does between these two

cant find it in the docs

[eternal needle]

You should do some c# basics if you're really unsure. This is a basic declaration, you have the access modifier, and a name but no type

[rich adder]

look at the type that comes out of Animator

[sleek orchid]

Hello guys!
I have an issue, I am trying trying to do a BrickBreaker game, in which I want my player not be able to move if his next move would overlap the boundaries. I thought that doing a invisible box collider to check collision is a good idea, is there any other way to approach this problem?

[bitter carbon]

? im confused'

[bitter carbon]

ik there is no type, just dont know what type im supposed to do

[languid spire]

a variable declaration is
modifier Type name
you are missing the Type

[bitter carbon]

yea im missing it

idk what the type is]

[rich adder]

you look at the docs just like I did

[bitter carbon]

i did.. i dont get where it tells me'

[rich adder]

the type is literally on the screenshot

you're gonna have trouble if you don't learn the basics of c#

[delicate venture]

sorry to bring this up again but if anyone could help me out

[bitter carbon]

i tried that earilier

?? this what u mean

[bitter carbon]

oh fuck me i spelt it wrong

yea i tried that at the start but i kept spelling it wrong

[rich adder]

what are you trying to do here anyway, what is the end goal?

[bitter carbon]

make a animation play

[rich adder]

why are you storing the controller then

just assign it directly to Animator in the inspector

you don't need a field for it

[bitter carbon]

i cant its a prefab

[rich adder]

yes you can , Animator Controller are just assets..

they can put on Prefabs just fine..

[bitter carbon]

idk my prefabs are all wierd

and have no area to add it

[rich adder]

this is not Animator

thats just the Animation clip inside the Model(unity treats them as Prefab)

[bitter carbon]

so this isnt my prefab?

[rich adder]

this is the model

You need an Animator component on a GameObject that contains the model

you should really be following a tutorial or something..

takes 5 minutes

[bitter carbon]

yea the gameobject is constantly deleted and spawned in

[rich adder]

what does that have anything to do with animations

[bitter carbon]

i have that

[sleek orchid]

How do I check collision on a Children Object?

[rich adder]

put script on child , send message to parent

[bitter carbon]

what im trying to do is change the animation controller everytime the gameobjkect is added otherwise it is blank

and it wont work

[sleek orchid]

What about collision in grandchildren?

[bitter carbon]

idr understand any better ways to do this

[sleek orchid]

Something like this...

[rich adder]

Make an actual prefab

[rich adder]

same thing.. reference the Root object u want,s end method to it

[charred heart]

drag the fbx file (the model) to the scene. Then drag the created gameobject to the project tab again to create a prefab.

[bitter carbon]

omg thanks so much

i have had so many problems cuz of this

[sleek orchid]

I will try ❤️ Thanks

[bitter carbon]

that makes sence

[rich adder]

you have many problems because you refuse to take the learning path properly

https://learn.unity.com/pathways

[tidal kiln]

you can have a rigid body on the parent and collider in children

[rich adder]

think they want to know which child was hit

[tidal kiln]

oh then yea send the message up manually

[ashen hatch]

Hello! I have a problem and I can't find an answer for it. I have a list of objects, right?

What I want to do is if list.count is bigger or equal 30, I want to remove all game objects from index 30 all the way to the end of the list, while also removing them from the list itself. So say I have list of count 45, I want to remove 15 objects from it.

[timber tide]

you sound like you got the idea, go for it

[lost anvil]

bump

[ashen hatch]

also I'm not sure if this is the right place to ask this question

[tidal kiln]

if list.Count > 30
for (start count at 30 to end)
destroy(list[i])
list.RemoveAt(i)

[ashen hatch]

I did this:

            {
                //Destroy(_waterInstances[_waterInstances.Count - maxWaterInstances]);
                _waterInstances.RemoveRange(maxWaterInstances, _waterInstances.Count - maxWaterInstances);

            }```

[polar acorn]

Close, but if you're modifying a list while looping over it, you should loop backwards from the end back to 30

that way you don't accidentally skip ones

[ashen hatch]

I have no clue how to do it and I've been at it for hours now

[rich adder]

funfact, if you type forr in IDE it gives you a reverse for loop

[timber tide]

the secret is to just forloop over the list and remove the 0 element by count

[tidal kiln]

this

[uneven locust]

Mind = blown

unironically

[polar acorn]

That works if you just need to remove n things from the list, but if you specifically need to remove from the end of the list you have to do the backwards loop

[ashen hatch]

loops always throw me for a... loop

its hard for me to understand them but I do know how to do foreach

[rich adder]

same thing

[ashen hatch]

later in code I do this

            {
                //we make sure each water has its own unique ID

                water._waterGUID = water.CreateWaterInstanceID();
                // then we force update for it to take effect and so each water actually spawns properly
                water.ForceUpdateWaterSettings();
            }```

[rich adder]

foreach wont work

esp removing list elements as you iterate

[ashen hatch]

are you able to help me by writing me an example? I know this is super lazy but this is how I've learned some programming. I apologise if it is, it's not my intention to seem like I'm unwilling but I really need some example.

For some reason I can't wrap my head around it.

[rich adder]

You already written it pretty much by words

[ashen hatch]

yeah but then how do I do it in the code? It's... idk

sorry XD

[polar acorn]

If the count is greater than 30, loop backwards from the end of the list back to 30. Destroy the element there, and removeAt that index

[ashen hatch]

This is clearest example, but how do I do the for(start count at 30 to end)?

that's what actually makes me confused

[tidal kiln]

its from end to start

[polar acorn]

https://www.w3schools.com/cs/cs_for_loop.php

[rich adder]

start wuld be assigning the index of loop to that

[ashen hatch]

so hold on:

for (int i = 30; i > 30; i++)
{

}

that?

[rich adder]

you need < list.count-1

but backwards loop is what you need

[ashen hatch]

im sorry for being so annoying btw, not trying to be

[tidal kiln]

for (int i = list.Count - 1; i > 30; i--)
{ }

[ashen hatch]

so that's how you do it? :o

[rich adder]

 for (int i = myList.Count - 1; i > 30; i--)
 {
     Destroy( myList[i].gameObject);
     myList.RemoveAt(i);
 }```

[ashen hatch]

so plugging in my variables

one second!

(I appreciate btw, this is what I'm talking about, now I can see how its done and I can just do it in future myself)

I'll plug my variables

[tidal kiln]

ok but make sure you know why it works

it seems like youre missing some fundamentals

about c#

or coding in general

[rich adder]

well yeah you learn by making mistakes too

[ashen hatch]

I do, but its actually incredible that I was able to somewhat program a working character controller

[rich adder]

like trying regular for loop and seeing why removing that way isn't as good as backwards etc.

[tidal kiln]

yup i made that mistake before

[ashen hatch]

I just never had to actually use loops

but for example

[tidal kiln]

and i made it today again lol

[rich adder]

Literally use them every day

[ashen hatch]

this is piece of code I wrote for zooming in camera, its nothing special but it makes me happy:

    {
        //Debug.Log("Zooming in");
        lockStoredValues = true;
        currentLerpTime += Time.deltaTime;

        if (currentLerpTime > lerpTime)
        {
            currentLerpTime = lerpTime;
        }

        float perc = currentLerpTime / lerpTime;
        offset.x = (Mathf.Lerp(offset.x, maximum, perc));
        offset.y = (Mathf.Lerp(offset.y, maximum, perc));
        distanceTarget = (Mathf.Lerp(distanceTarget, maxDistance, perc));
        cam.fieldOfView = (Mathf.Lerp(cam.fieldOfView, 30f, perc));



        yield return new WaitForSeconds(1f);
        //Debug.Log("This is Done zoom In");
        currentLerpTime = 0f;
        canZoomOut = true;
        canZoomIn = false;
        yield break;
    }```

[rich adder]

anytime you got to do something more than 1 thing you need loops

[ashen hatch]

then at zoom out i do the reverse, except going back to stored values

[rich adder]

the lerp is wrong

[ashen hatch]

it is?

strange, because it actually works

it is supposed to move camera offsets to 0,0, bcs camera is slightly offset

[rich adder]

should be in a while loop currentLerpTime += Time.deltaTime;

https://unity.huh.how/lerp/coroutines

example of proper Lerp

[ashen hatch]

oh while loop I know, I should look into it

(sry my code is a mess lol but im still happy to improve it)

[tidal kiln]

are you goingn for a smooth zoom?

[ashen hatch]

yes

[tidal kiln]

i dont understand how it works then

[ashen hatch]

it smoothly zooms in when ragdolled, then when character gets up, zooms back out

[rich adder]

cinemachine has that built in btw if you switch between 2 cameras

[ashen hatch]

nope, use singular camera

[tidal kiln]

theres no way that code you wrote is smooth zooming

[ashen hatch]

it does work, idk why

[ivory bobcat]

I'm guessing they're starting the coroutine again after finishing in Update based on some bools

[ashen hatch]

yes, exactly

[sleek orchid]

At this moment I am trying to define some boundaries that if they collide my player can't move towards that direction. I am thinking that the only way to do this is by attaching one script to the GrandChild BoundLeft; another script to the GrandChild BoundRight then compare it in the PlayerMovement script. Is this the most optimal way?

[tidal kiln]

oh i dont think you should be starting a coroutine every frame

[ashen hatch]

oh no its not

only when certain conditions are met

it should be triggered

and then only once

[tidal kiln]

ok nevermind i dont get whats happening or how its working lol

[ivory bobcat]

You really should use a loop though to avoid having to maintain bools and checking when to start again

[rich adder]

no the optimal way is using Raycasts

[ashen hatch]

I will do, but I will say that I have a looong way

[sleek orchid]

Raycasts... Okay I will try to learn hem'
Thanks in advance ❤️

[ashen hatch]

I code or try to code in like 2-3 months?

[tidal kiln]

youre doing good so far keep up the learning 🙂

[ashen hatch]

I admit one thing, for character physics

I use PuppetMaster XD

its actually kinda fun to work with

[ashen hatch]

        {
            StartCoroutine(camZoomIn());
            blockingRadius = 0.1f;
        }```

those are conditions

[ashen hatch]

I have plugged my variables into this. This is how it looks:

            {
                Destroy(_waterInstances[i].gameObject);
                _waterInstances.RemoveAt(i);
            }```

[twin granite]

When i put my blender object in unity . In Hiearchy it look like packet not like cube.

Is it good

[tidal kiln]

what

[rich adder]

does it work?

[rich adder]

this is not a code question

[flint heath]

how would I go about modifying a specific tilemap tile at the point where the player is? something like what is below

public void Swing()
{
    if (Tilemap.GetTile(playerBody.transform.position))
    {

    }
}

[ashen hatch]

allow me to check, I kinda need to restart my PC due to Win 10 update -.-

[rich adder]

SetTile

[twin granite]

Where can i ask that

[flint heath]

ah, but how would I go about getting the specific tile that the player is on?

what i posted above has an error message because what is inside the parentheses isn't a vector3 integer or something

[rich adder]

use the tilemap.WorldToCell method first

cache player pos as that

[rich adder]

probably in #💻┃unity-talk or #🔀┃art-asset-workflow

[twin granite]

Thank you

[autumn tusk]

im wondering

how do i concatinate multiple strings in a for loop

[ashen hatch]

Sir you and @tidal kiln are saviors. It works. So let me explain what I tried to do. I am learning to spawn instances. As a measure, I wanted to limit amount of water instances in my scene as optimisation to make sure it works smoothly.

I could use object pooling, I know

but I want to learn pooling later

[wintry quarry]

use a StringBuilder
Or just string.Join

[ashen hatch]

as its much more difficult.

[rich adder]

honestly pooling is pretty easy

unity has its own thing now for it

built in

[spiral narwhal]

How would I go about doing a wheel selector? Like the weapon wheel in GTA or Red Dead?
I'm assuming I take the mouse position and divide it into N sections? Then checking which section the mouse is in? Or is there a better way?

[tidal kiln]

i had no idea

[ashen hatch]

Yes but if you have procedural generation based on prefabs and each prefab can be spawned x amount of times, then it kinda can break things

[rich adder]

https://youtu.be/tdkdRguH_dE

[ashen hatch]

I need to implement anti-intersection measure next

whats the best way to ensure rooms dont intersect?

[rich adder]

probably colliders and doing overlap checks

[tidal kiln]

you got this 🦾

[timber tide]

use an alg that doesnt intersect

[ashen hatch]

but only once, I don't want to run this forever

I already got it somewhat working

[ashen hatch]

thank you sir, know that you've saved me a ton of headache.

[ashen hatch]

Would it be possible to make some sort of "room volume"?

I will do it myself but I try to feel out the best way to do it

Collisions are expensive, I take

[rich adder]

thats how I did it a few times , had to resort to colliders because my doors are connected through opening

Physics overlaps are fairly cheap with non-alloc

also you only doing it when generating

[ashen hatch]

That's exactly what I want todo, connect rooms through aligned doors that snap to grid

[rich adder]

some algos i used expected same sized rooms / shapes so I had to resort to physics

as I often do

[ashen hatch]

I will not restort to room door sizes, so any differencies will be covered up by geometry

I think this would be solely because I want it to be as random as humanly possible.

[rich adder]

https://youtu.be/rfKcpp8UDQ0 this is what i watch a few years back when i did t

I did something similiar basically with colliders

[sleek orchid]

I've tried using Raycasts as Mr. Navarone told me. However, It doesn't seem to be working as intended. It is always printing out "False"

using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public int moveTiles = 2;

    [Range(0, 10)]
    [SerializeField] int maxRay = 2;
    
    public GameObject objectBoundaries;

    void Awake(){
        Debug.DrawLine(transform.position, new Vector2(-maxRay, 0));
    }
    void Update()
    {
        print(CanMoveRight());

        if((Input.GetKeyDown(KeyCode.D) || Input.GetKeyDown(KeyCode.RightArrow)) && CanMoveRight()){
            transform.Translate(new Vector2(moveTiles, 0));
        } else if((Input.GetKeyDown(KeyCode.A) || Input.GetKeyDown(KeyCode.LeftArrow)) && CanMoveLeft()){
            transform.Translate(new Vector2(-moveTiles, 0));
        }
    }
    bool CanMoveRight(){
        if(Physics2D.Raycast(transform.position, new Vector2(maxRay, 0))){
            return false;

        return true;
    }
}

[ashen hatch]

My friend allowed me to port his map from Source Engine to Unity, this is why I'm basically trying to make it procedural, because it's liminal spaces hahaha

[flint heath]

dude i feel like a god right now i just used the unity documentation and wrote a bunch of random lines of code and it worked first try

    public void Swing()
    {
        GridLayout gridLayout = cropMap.GetComponent<GridLayout>();
        Vector3Int cellPos = gridLayout.WorldToCell(playerBody.transform.position);
        Debug.Log("Swung At" + cellPos);
    }

ty for help 🙏

[autumn tusk]

c# is being picky again

i have no idea what it wants me to do here

[rich adder]

pretty sure tileMap alreayd has WorldToCell you don't even need GridLayout component reference, but hey if it works lol

[autumn tusk]

i tried putting in square brackets but i dont want to set an index

[rich adder]

use the static method

as it says

[flint heath]

there was nothing on unity docs called "tilemap.worldtocell, only gridlayout.worldtocell" with correct capitalizeation cos im dumb

[rich adder]

string.Join

[autumn tusk]

ah right

got it

[rich adder]

yeah the docs is kinda weird on that , but there is ! believe me

just incase you don't believe me 😛

you know why it works?

Tilemap is GridLayout :p

[flint heath]

ohh

[sleek orchid]

After some tweaking I've managed to solve it ❤️

The Raycast was pointing ↖️ hehehehe

[flint heath]

How can I add a variable to each tile in a tilemap individually?

[eternal needle]

https://learn.microsoft.com/en-us/dotnet/api/system.string.join?view=net-8.0
best to look at the docs always, they have examples.
Also you should really use stringbuilder if you need to do this often

[autumn tusk]

im basically just making a wordle clone that generates a series of 5 random numbers

i only need one string for this

[eternal needle]

do you even need to concat individual numbers then? why not just 1 random 5 digit number

[autumn tusk]

actually yeah

was gonna say its a bikelock system but actually im not thinking straight

[wintry quarry]

5 random numbers of how many digits each?

[autumn tusk]

it would work near perfectly

alright that was easy

but yeah i should learn how string.join works

[eternal needle]

#💻┃code-beginner message

[rich adder]

what kind of variable

[flint heath]

a float

[rich adder]

you can make custom tiles

[flint heath]

I'm trying to make something so that when you click when you are on top of a tile, it decreases the value of a variable on that tile, and then the value of that variable is kept proportional to the darkness of that tile, so when you click repeatedly on top of a tile, it gets darker

[rich adder]

public class CoolTile : Tile {
public float MyFloat```

yeah use custom tiles

then when you GetTile

you can do cs var tile = tilemap.GetTile<CoolTile>(Tilepos); tile.MyFloat += 1;

or whatever

[flint heath]

there's going to be a lot of the tiles though... I don't think i'd be able to name each of them individually

[rich adder]

what?

each tile is its own Instance of Tile

idk what you mean by naming

[flint heath]

so it's not on a tilemap?

[rich adder]

tilemap is a container for Tiles

[flint heath]

ah ok

ima take a break rahh

[dusty silo]

I have a list of custom objects that I am iterating through. Is there a way to better visualize how it's working? Could I use something like coroutines to show a visual "replay" of what happened?

[rich adder]

how's what working ?

[wintry quarry]

You're iterating them and doing what?

Is this a card game?

[dusty silo]

I'm trying to make a shape less concave

[dusty silo]

No, I'm doing a second pass of a sorting method

[sleek orchid]

ey ey! I am trying to learn TileMaps, while doing a Brick Breaker, any idea how to only destroy 1 tile when the ball hits it?

[rich adder]

tilemap.SetTile(cellPos, null)

why are you using tilemap for that though

[dusty silo]

Currently, I have three variables lead, follow and tail that run through the list and look at the triangle formed by the three. If it determines that the triangle is concave/vex it will then consider swapping either tail and follow or follow and lead. To stop it from creating self-intersections, I am running several checks to see if the hypothetical new configuration will intersect with any surrounding lines. However, my system does not seem to work at all. It will make swapping decisions that intersect through the entire shape while leaving obviously concave parts alone. Can I use co-routines to show me, on a human-visible delay what happened?

[sleek orchid]

I am..

[rich adder]

the question was "Why"

[sleek orchid]

oh..

sorry xdd

I thought it would be a good idea

It isnt?

[rich adder]

nah it will be cumbersome

if you want it for the Grid, you can use that with regular prefabs

interacting between worldObjects and TIlemap is a pain because of the different coordinate systems

[sleek orchid]

oooooh

That's was of great help.

So... we use tilemaps to build maps?

[rich adder]

yeah its better for static maps

[sleek orchid]

Cheers, you are cool s2

Imma go back to learning

[rich adder]

oh btw your tiles look bit blury make sure you uncheck Filtering and compression on spritesheet

keeps the crisp pixel perfect

[sleek orchid]

I've deleted them, but I will remember that in the future

[rich adder]

ohh..why you could still use those tiles lol just put them on the sprite renderer.
just make sure your Pixel Per Unit , matches original slices size

[sleek orchid]

🫡

Mr. Navarone?

Is having +100 Blocks a problem?

xdd

[rich adder]

ur fine lol

[sleek orchid]

(That made those pixels look so much better 🫡 )

[carmine sierra]

This is my current code for detecting colliders, right now it seems to only detect one collider at a time, I assume this is because it is triggered when a collider enters it, one at a time. But how could I detect multiple colliders at a time?

The long way would be to detect this script's gameobject's collider from the other collider's instead of this way round

BASICALLY: I want to detect multiple colliders at a time

[eternal needle]

the collision messages will trigger once per collider, you can use the built in physics functions if you want an array of them all at once.
though this code looks very weird that you are comparing to a different collider instead of some layer, tag, or if a script exists

[tribal pendant]

hey quick question, what is the difference between "Input.GetKeyDown(KeyCode.Mouse0)" and "Input.GetMouseButtonDown(0)"?

[rich adder]

ones called GetKeyDown ones called GetMouseButtonDown

[tribal pendant]

understandable have a good day

[tribal pendant]

no but fr is there no difference at all?

[rich adder]

nope

[carmine sierra]

what built in physics will trigger an array of colliders?

[eternal needle]

https://docs.unity3d.com/ScriptReference/Physics2D.html

[carmine sierra]

so istouchinglayers?

that would definetly allow for multiple colliders at once to be detected?

I need both at the same time, or one, or either

if you get what i mean

[eternal needle]

no, scroll down further. there is a bunch of overlap methods you can use

[carmine sierra]

ohhh okay

thank you

so overlapcollider

[eternal needle]

yea it will fill an array you give it with the results

[carmine sierra]

how would I get these in an array?

just the bottom 3

I haven't used an array yet in unity

[eternal needle]

the physics functions will fill the array of whats currently overlapping. you dont fill it yourself

[carmine sierra]

oh okay

so i can return that array

and then compare it within an if statement

if (arrayname == [array]) something like this?

[eternal needle]

you should reallly do c# basics first if you havent used arrays. this all seems backwards because you are comparing to specific colliders. This will become a pain to do if you suddenly want to have another woodCollider, or 10 of them

[polar acorn]

What, specifically are you trying to do?

[carmine sierra]

there will be many wood colliders as they will be instantiated multiple times

[polar acorn]

Why are you trying to compare arrays?

[polar acorn]

Then this plan definitely won't work

[eternal needle]

Yea so how are you gonna drag these in inspector for the user at runtime?

[carmine sierra]

basically I can only spawn wood in my game on the condition it is touching/not touching certain colliders

[carmine sierra]

I assume i can group my wood collider's into an array?

each time they are spawned

by just appending them

everytime a new wood spawns in

if that sounds right I'll try it out

[polar acorn]

If you just need to check if the collider you've hit is wood, why not use tags

[carmine sierra]

and that array will be appended onto the colliders array

[carmine sierra]

different to layers?

[eternal needle]

so everytime you overlap with something, you are gonna compare it to every single spawned collider? just use layers, tags, or have a script on the object and GetComponent it

[polar acorn]

Tags and Layers are indeed different things

[carmine sierra]

okay ill check out what tags are then

[carmine sierra]

yeah that was the original plan lol

[summer stump]

They're the things right below the name of the gameobject in the inspector, on the left of layers. There is more to it than that, but you must have seen that before, right?

[carmine sierra]

so it is essentially a grouping mechanism#

[summer stump]

Sure. It's a way to say a gameobject belongs to a group I guess
It is "tagged". You can then check that tag in conditionals
Use .CompareTag("myTagName")

[thorn crater]

I have a weird behaviour in my in my Editor right now, for some reason when i play, the objects in the scene are getting "refreshed" and it says: "This GameObject only exists at runtime", anyone else had this behaviour? If yes, is there a way to fix it?

[carmine sierra]

should i make a tag for every collider i want to check or separate them (not every collider will have the same effect)

[eternal needle]

Basically like a group, but this grouping really is just a value (the tag name) thats assigned to it. Then you are doing logic based on the tag.

[polar acorn]

What do you mean by "refreshed"?

[carmine sierra]

but every wood will have the same result so those should be tagged i assume

[summer stump]

Depends on how complex things will be. You get up to 32 tags.
As many objects as you want can be one of those 32

You may want to consider checking if the object has a script though, if it is very complex. I think that was recommended above along with layers and tags

[thorn crater]

Well lets say i selected a gameobject inside the hierarchy, and while its selected i press play. Then suddenly my inspector is empty and there is only a text saying:
"This GameObject only exists at runtime"
And when i select this Object again, my Editor UI is gone, as i build the whole ui inside the editor and for some reason the object gets reinstantiated i believe

[carmine sierra]

well there are just 3 types of colliders i will be checking for, and there will be two outcomes (flip on/off a bool)

[summer stump]

Alright. Perfectly fine use of tags then

[polar acorn]

Can you send a screenshot of your entire editor window before and after hitting play?

[carmine sierra]

no scripts within the colliders

sorry I understand what tags are now but I don't understand how this will allow for multiple colliders to be detected at the same time

[summer stump]

Each collider would need to be on a different object

Is that the case you are using it for?

[polar acorn]

Why do you need multiple colliders to be detected at once

[summer stump]

It is non-trivial to detect specific colliders on the same object unless they are different types (like you could check if it is a sphere or capsule).

[carmine sierra]

im not sure what you mean by case but yes each collider will be on a different object

[summer stump]

Then what is the issue?

[carmine sierra]

because in the case my object is touching a valid collider and an invalid collider, I want the bool to be false (so the user cannot place the wood down in that position)

[summer stump]

Check each collision for the tag

[polar acorn]

This is something with a custom inspector. That inspector appears to be broken. Is this your own custom inspector script?

[carmine sierra]

in the case I used && here (which doesnt work as one collider is detected at a time), I intend for both colliders to be detected at once

[lost anvil]

bump

[polar acorn]

So you would do an OverlapAll and check if any of those colliders contain an invalid tag

[carmine sierra]

when I use or (which works) I want either collider to have the same effect when entering the gameobjects collider

[thorn crater]

i had this issue with the gameobject in runtime before already, but it started to get annoying with the custom editor

[carmine sierra]

ohh okay

[slender nymph]

Just FYI it is only layers that is restricted to 32 (since that uses a 32 bit int for the mask). The max tags is something crazy high like 100k 10001

[carmine sierra]

before I search how to do this, would this still require ontriggerenter2d

[polar acorn]

So if this is an editor script you wrote yourself, you should probably ask this in #↕️┃editor-extensions

[polar acorn]

Search first, then ask

[carmine sierra]

fair

[summer stump]

Oh woah. I had always just assumed! I honestly never use many tags at a time

Thanks!

[thorn crater]

no this is just a script which got affected aswell, but this behaviour of GameObjects getting refreshed or reinstantiated is a behaviour which also appears in regular components / scripts

[polar acorn]

That "This GameObject Only Exists At Runtime" window is itself a custom inspector. That's not a built in Unity thing

[thorn crater]

its none of my scripts , and i imported this inside another Project with different version and it happens again

[polar acorn]

Unless it's part of some package I haven't used, that error window is not something provided by unity. I can't even find anything online about it. It's probably custom to some asset you're using

[queen adder]

Hey guys, I'm currently learning C# on CodeCademy and i have a small question ig, what's the difference between C# for websites and GameDev (Unity)?.

[iron mango]

hey, is there a way to use an interface but not do

public int Team
    {
        get { return team; }
        set { team = value; }
    }

for every single value? i have a huge code block because i did that for like 20 variables
or is that normal xD

[rich adder]

the framework specific api

[polar acorn]

The language is the same. The libraries are different

[polar acorn]

public int Teams {get; set;}

[iron mango]

can i just use the same value?

[polar acorn]

I don't know what you mean

[iron mango]

thought i have to use a different one

[polar acorn]

You can use an auto-property if all you're doing is getting and setting it

[queen adder]

ah alright, thx

[iron mango]

hm ok

[iron mango]

now i can't use a header anymore idk why

ah

it's not visible anymore

[iron mango]

yup i have to do that ._.

or i can't see them in the inspector

[rich adder]

because you cannot put that attribute on property

it expects a field

[iron mango]

yeah i want to edit it in the inspector

[iron mango]

so i have to do that i guess

[rich adder]

why is it property anyway

[iron mango]

wdym

[rich adder]

cause you made it public get / set

just make it a field

[iron mango]

huh?

i mean i have multiple spaceship scripts but they have to have the same values, also for mod support,

idk ._.

[rich adder]

what does that have anything to do with a field vs property

[iron mango]

idk

what u mean xd

[rich adder]

you seem confused what they even are lol

[iron mango]

i am

idk don't question my brain

but everything works, multiplayer and mod support, so i am not dumb i guess

[rich adder]

you made multiplayer but don't know difference between fields and props

[summer stump]

public int thing; <-- not property

public int thing { get; set; } <-- property

[iron mango]

yes, i mean i use an interface, so i can use the values from there

that's why

-> the unity docs told me to so don't hate me pls

[rich adder]

yes interfaces cannot have fields

[iron mango]

i can speak perfectly, better than many ppl but i am not sure what a verb is

xd

a do word i think

XD

[iron mango]

sooo, i do have to make huge code blocks then

[rich adder]

I guess ? idk your project

[iron mango]

😭

man

[summer stump]

Those are called properties. And yes, you must use properties for interfaces

[iron mango]

ok.

[summer stump]

You can do what digi said though
public int Teams { get; set;}

[iron mango]

just looks weird because i want all scripts with that interface to access all values (like 20 or more) and that's what i use for mods, a custom ship just has to use that interface but can have it's own script

[summer stump]

Then put [field: SerializeField] above it

[iron mango]

uh ok i try

[iron mango]

nice, thank you

[carmine sierra]

what is contactfilter2d?

i need it as a parameter for overlap

[summer stump]

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

[carmine sierra]

yh i tried reading that

what is filtering?

[summer stump]

Like the word itself?
https://www.merriam-webster.com/dictionary/filter

It's exactly the same in and out of unity

[carmine sierra]

no in terms of unity

[summer stump]

It's exactly the same in and out of unity

It rejects some results, FILTERING what it returns

[carmine sierra]

so a contact filter would mean what do I want to detect overlaps for?

[summer stump]

Yeah I guess so

Yes, i get what you mean now. That is correct

[carmine sierra]

the overlap functions want a second parameter of 'Colliders2D[] results'

what does this mean?

[summer stump]

You create an array variable, and pass it in. Overlap fills the array with the results

[carmine sierra]

ohhh okay

Collider2D overlapingColliders = collider.Overlap(ContactFilter2D.NoFilter, collider, )

so instead of this

I can put 'overlapingColliders' as the second parameter

Sorry, not 'instead', as that is wrong

but yeah

[summer stump]

Well no, because it needs to be an array, and overlapingColliders is a single collider

[carmine sierra]

so what is wrong about my conclusion

there is no data type for multiple colliders is there?

collider.Overlap(ContactFilter2D.NoFilter, overlappingColliders);
what is wrong with this?

[summer stump]

Is overlappingColliders an array now?
Are you getting an error or something?

[carmine sierra]

contactfilter2d.nofilter is the error

[summer stump]

Wait... it just says Overlap... can you link the docs for the method you are trying to use?

I don't use 2d that much

[carmine sierra]

https://docs.unity3d.com/ScriptReference/Collider2D.OverlapCollider.html

[summer stump]

Ok, can you send the EXACT code you've written then, because that was not this

[carmine sierra]

i am trying to get any colliders which the gameobject's collider goes over

[summer stump]

What does the error say?

[carmine sierra]

and put their gameobjects into the overlappingcolliders array

Argument 1: cannot convert from 'method group' to 'ContactFilter2D'

[summer stump]

I haven't used it before, but try ContactFilter2D.NoFilter()

[carmine sierra]

doesnt work

[rocky canyon]

new ContactFilter2D().NoFilter()

[summer stump]

Dang, I am kinda lost.

Ohhhh, interesting

[carmine sierra]

collider.OverlapCollider(new ContactFilter2D().NoFilter(), overlappingColliders);
}

[rocky canyon]

very, the documentation has no examples

[carmine sierra]

doesnt work

[summer stump]

Ahh yes, I see it's a steuct

[rocky canyon]

i had to find examples on threads

[summer stump]

Probably not inside the method

But before it. Maybe in awake or start

[rich adder]

You don't use New() btw it already has one for NoFliter
https://docs.unity3d.com/ScriptReference/ContactFilter2D.NoFilter.html

[teal viper]

Error?

That's before turning it into a method

Yeah, just wanted to make sure you were caught up. Sorry for the confusion

[polar acorn]

You either need the new and the () or you need neither of them

Either new ContactFilter2D().NoFilter() or ContactFilter2D.NoFilter()

[teal viper]

You should probably create the struct ahead of time.

[carmine sierra]

second has red lines, first gives yellow underneath the whole line

[carmine sierra]

what does that mean?

[polar acorn]

Create a ContactFilter2D and store it in a variable. Then use that inside the Overlap call

instead of trying to do it all in one line

[carmine sierra]

damn why do they need all of this

[summer stump]

#💻┃code-beginner message

[carmine sierra]

when you just dont want to use a filter

what data type is the contactfilter

[rich adder]

#💻┃code-beginner message

[rocky canyon]

its a ContactFilter2D

what are the filter types?

[carmine sierra]

ContactFilter2D NoFilter = new ContactFilter2D.NoFilter();

doesnt work

[summer stump]

Reduces allocations I guess?

[polar acorn]

Just create an empty one, don't worry about the NoFilter yet

[carmine sierra]

collider.OverlapCollider(new ContactFilter2D().NoFilter, overlappingColliders);

if you mean like this, it doesnt work

ContactFilter2D NoFilter;

and that is nofilter

[polar acorn]

No, I mean create an empty one and store it in a variable

and pass that variable to the function

[summer stump]

As we said, do not do it inside the method

[rocky canyon]

ContactFilter2D contactFilter = new ContactFilter2D();

[carmine sierra]

is this empty though

ohh ok

[polar acorn]

That's not empty that's nonexistent

[rocky canyon]

lol

[polar acorn]

there's a difference between a shoebox with nothing in it and the cosmic nothingness of the void

[carmine sierra]

fair

no such thing as nothingness

acc lemme stick to coding

[polar acorn]

Oh no, nothing is definitely a thing. It's just not a ContactFilter2D

[rocky canyon]

void is nothingness

[polar acorn]

Which makes it not work for your purposes

[carmine sierra]

collider.OverlapCollider(contactFilter, overlappingColliders);

this should have worked right?

[rocky canyon]

TIL about contactfilter2d

[carmine sierra]

sorry whats TIL

[rocky canyon]

Today I Learned

[carmine sierra]

fair enough

[rocky canyon]

just waiting for the working result 🍿

[carmine sierra]

'Collider2D.OverlapCollider(ContactFilter2D, Collider2D[])' is obsolete: 'OverlapCollider has been renamed to Overlap (UnityUpgradable) -> Overlap(*)'

and unity is asking for script changing consent 👀

[rich adder]

nice

[rocky canyon]

you need 3 parameters dontcha?

[carmine sierra]

really?

[rocky canyon]

i think so.. collider contactfilter2d array

[grim stream]

is there a code event in the Animation class for when the animation is done playing. i know the timeline (cutscene) thing has one of those

[carmine sierra]

documentation just says: Declaration
public int OverlapCollider(ContactFilter2D contactFilter, Collider2D[] results);

[rocky canyon]

u can put an animation event on the last frame

[rocky canyon]

which documentation are you looking at? mines different

[carmine sierra]

theres also a physics2d one, not sure which to use

[rocky canyon]

ohh, Im looking at Phsyics2D.OverlapCollider

[carmine sierra]

yeah but what is the appropriate use case? I have no idea

[rich adder]

what are u trying to do

[rocky canyon]

me neither

[rich adder]

Collider2D.OverlapCollider works fine

[carmine sierra]

i want the script's gameobject to detect colliders it touches

[rich adder]

show the full line you wrote

[carmine sierra]

collider.OverlapCollider(contactFilter, overlappingColliders);

[rocky canyon]

ahh, its the same way,, just two different syntax's

[carmine sierra]

ContactFilter2D contactFilter = new ContactFilter2D();

[teal viper]

Why not OnCollisionEnter then?

[carmine sierra]

idk if it's the same, but i tried ontriggerenter2d

but it is not appropriate for my use case

[summer stump]

collider.OverlapCollider(contactFilter.NoFilter, overlappingColliders);
?

[rocky canyon]

^ yea i wouldnt see why that wouldnt work

[teal viper]

Why not?

[teal viper]

NoFilter is a method

[carmine sierra]

doesnt work, lemme check the error

[summer stump]

I don't know anything about it haha

[rich adder]

it should

[carmine sierra]

cannot convert from 'method group' to 'ContactFilter2D'

[summer stump]

Ah, well, it was just a guess, sorry

[carmine sierra]

np

[rocky canyon]

me neither.. im just using process of elimination at this point 😄

[carmine sierra]

appreciate any help

[teal viper]

We went over it already

[rocky canyon]

NoFilter() ?

[carmine sierra]

I want to detect multiple colliders at a time, as otherwise the game's function doesn't work properly

[teal viper]

Can you explain why OnCollision/TriggerEnter is not good enough for you?

[rocky canyon]

hehe, im interested as well

[carmine sierra]

i don't just want to detect one collider at a time

[teal viper]

You can with the collision message

You just need to cache whatever you're colliding with

[rocky canyon]

wats the odds that multiple colliders will enter at the same frame? ^

[carmine sierra]

zero

[teal viper]

Even if they do, the function would be called for all of them afaik

[rocky canyon]

well it should still work for u like dlich mentioned

[rich adder]

OnCollisionEnter add to list of colliders
OnCollisionExit remove it from list

[carmine sierra]

if they enter at two different frames it would call the function?

[rocky canyon]

each one would call it

[carmine sierra]

give me a second to think how that would work

[rocky canyon]

and add themselves to the list

[carmine sierra]

ohh and then compare to the list?

[rich adder]

thats if you want to store them, or just call your functions directly. i

[carmine sierra]

like if both colliders are in the list, then so and so

[rocky canyon]

if(!inList){AddToList()}

[rocky canyon]

you could do w/e logic u want to do afterwards.. comparisons or whatnot

each time one enter the collision -> add to list -> now that its in the list do logic to check stuff

[carmine sierra]

okay cool that sounds good

[carmine sierra]

What is wrong with this:
Collider2D[] overlappingColliders;
...
void OnTriggerEnter2D(Collider2D otherCollider)
{
if (!overlappingColliders.Contains(otherCollider))
{

    }

[timber tide]

it's missing debugging

[carmine sierra]

but overlappingcolliders is not valid

in the if statement

so not sure how to debugf

says there is no definition for contains

[crude prawn]

there is something wrong with this line if (!overlappingColliders.Contains(otherCollider))

[timber tide]

arrays dont have contains I believe without linq

[crude prawn]

its probaly overlappingcolliders cuz you put a ! infront of it so its a bool or smthing

[frosty hound]

Arrays don't have a Contains function

[carmine sierra]

ohh okay

so how do you check if an item is in a list for an array

[frosty hound]

Iterate through it and check

[timber tide]

ye old fashion way

[carmine sierra]

so there is nothing resembling

inlist?

[frosty hound]

That would be a contains function

[summer stump]

Why use an array for this instead of a List
Oh, you're going over that now

[undone harbor]

what editor do yall use?

[carmine sierra]

i thought they were initialised the same way

[summer stump]

Nope

[carmine sierra]

Collider2D[] overlappingColliders;

[summer stump]

Collider2D[] <- array
List<Collider2D> <- list

[carmine sierra]

oh okay

[summer stump]

Like IDE? I use visual studio
Vs code is common, as is Rider

[faint osprey]

    {
        if(other.GetType() == typeof(SphereCollider))
        {
            inMagnetRadius = true;
        }

        if (other.GetType() == typeof(MeshCollider))
        {
            Player.BroadcastMessage("CoinPickup");
            Destroy(gameObject);
        }
    }```

how come the first if statement is called but the 2nd one never is

thats my object

[carmine sierra]

it works now 🙏

[undone harbor]

I see, thanks

[rocky canyon]

Started with Visual Studio, I use Rider when it's Freebie Giveaway season, and recently Installed and swap between VSCode and Visual Studio.. Visual Studio is my favorite so far.. and the editor that got me thru my beginning unity learning

[vale karma]

is there a difference when using the name 'Game Manager' for a script compared to a different name? This one changes the script to a cog wheel, and it looks cool, i just dont wanna mess anything up

[rocky canyon]

it gives it an icon, that is all

you can use the name no problem

[gaunt ice]

You can customise the icon iirc

[rocky canyon]

thats what its meant for.. ^

[vale karma]

oh no way

your joking

[rocky canyon]

yesway

[vale karma]

i shouldnt have asked. im doing it now

[rocky canyon]

Other and go crazy

[cosmic dagger]

yep, you cna create custom icons for any of your scripts or assets . . .

[vale karma]

oh im gonna put phalises everywhere

[rocky canyon]

Rabbit-Hole Discovered!

[vale karma]

lollll, thanku for the tip guys. Unity is much more fun now

[cosmic dagger]

i already went there . . .

[rocky canyon]

same 🤣

[vale karma]

oh i was gonna put like an old timey script, and probably forget waht it really was

probably like a banana for a game object

[rocky canyon]

nice, mines more flair.. urs is useful

whats the inspiration from? or is that ur own custom icon set

[cosmic dagger]

i kept mine simple. CS is a regular script. ED is an editor script. SO is a ScriptableObject . . .

custom icon set . . .

[rocky canyon]

noice 👍

[vale karma]

That helps alot

[cosmic dagger]

different colors to easily see which is what. i added types to see if it was too much or not . . .

E for enum, T for generic, I for interface, {} for class. Folder is an actual folder icon, but that can be confused for an actual folder to click on . . .

[eternal needle]

Name a script Folder

[vale karma]

😮 omg what happensss

IT BECOMES A FOLDER?

BUT ITS A SCRIPTTT
ohh what does it meaaannn

[silent valley]

This warning has gotten me a bit confused. I remember having this exact warning months ago and I never found a solution. Any help

[tacit birch]

I'm trying to set up a script so that my projectile does damage to an enemy.
For some reason though, it doesn't seem to be detecting collisions at all.
Both of the GameObjects have a Rigidbody 2D and a BoxCollider 2D.
Can anyone help me figure out what's wrong with this? D: It's actually driving me crazy

Enemy:

Projectile:

I also added this bit of code for the Projectile:

private void OnTriggerEnter2D(Collider2D collision)
    {
        Debug.Log("Collision detected with: " + collision.gameObject.name);
    }

[vale karma]

having the object discrete would probably cause issues

interpolate and collision detection should most likely be changed

[tacit birch]

For Interpolate, should I use Interpolate or Extrapolate?

[vale karma]

using UnityEngine;

public class GameManager : MonoBehaviour
{
    [SerializeField] private GameObject[] cards;
    [SerializeField] private GameObject gridLayoutEmpty;


    private void Start()
    {
        for (int i = 0; i < cards.Length; i++)
        {
            Instantiate(cards[i], gridLayoutEmpty.transform);
        }
    }

    public void FlipCard()
    {
        // Based on which card/button clicked, change sprite to that index #.
    }
}

im wondering if i could somehow store an index number along with each button, and pick it out once i click on one of the buttons

woopsie

[cosmic dagger]

try each one and see if either work . . .

[vale karma]

i feel like ``` cs
int index = #;

in a for loop would just recreate the same variable... i know there has to be something better than making a bazillion buttons

[tacit birch]

Hmmm I changed both of the objects to have Interpolate/Extrapolate as well as set the Collision Detection to Continuous. It doesn't seem to detect anything still

[vale karma]

post some some of the relevant code

[cosmic dagger]

how fast is the projectile moving?

[tacit birch]

this was the only code I was using to test collisions

[gaunt ice]

Use lambda expression to capture the index

[tacit birch]

it isn't moving at all. I'm just using the Player to lure the Enemy AI into the object with the collisions atm

because for the projectile, I wasn't able to get it to move either lmfao

[vale karma]

lambda? i heard the term before , ill give it a search

[silent valley]

could I get help please 🥺

[gaunt ice]

You probably have used it ()=>{}

[vale karma]

i see how its written yea, but ive never used it. It seems simpel enough, but i still dont see how it pulls specific indexes out the hat

[gaunt ice]

Or making a struct/class (you can use monobehavior) associate with the button and store the index, when onclick, inform the game manager its index

[cosmic dagger]

your code and image are for the projectile. not sure how we can help fix the projectile if you're not moving it to collide with the enemy . . .

[gaunt ice]

Int index=i
Onclick.addlistener(()=>{gamemanager.somemethod(index);});
You must assign i to local variable

[tacit birch]

i wasn't aware that the projectile had to move in order to detect collisions

The provided examples above were to test collisions.
I kept the projectile's movement static to check if the enemy moving into the object will be detected

[vale karma]

Its so weird. It looks easy, i go to type it, then its like, where, what and how do i type this. Its annoying bc it seems so easy

[summer stump]

Show the string you pass in and the state

[cosmic dagger]

make sure the animation name (variable) matches the states in Mecanim . . .

[gaunt ice]

https://forum.unity.com/threads/not-sure-when-to-use-lambda-expressions-can-someone-give-me-examples.389983/

[vale karma]

haha thats perfect thanku

[silent valley]

I managed to fix it. If i changed the name. it worked. I have it to "Roll" or anything else, it works. If i set it back to "Roll_Foward_01" it gives me those warnings.

[summer stump]

Do you have a state called Roll_Forward_01 exactly, including capitalization and the underscores?

[silent valley]

yes

one sec

sent wrong one

[vale karma]

i realized thats the same exact page i was reading. Its not giving any option to add the .addlistener method after. give me a lil bit i might find out

[summer stump]

Can you not crop that please. Is that actually a state?

Sorry, missed the icon, that is a state

Is the state in the animator though?
You should probably just be asking in #🏃┃animation honestly

[gaunt ice]

It is a method of button.onclick (unity event)

[vale karma]

got eeet, im gonna watch a few videos to get the meaning of it. No point in asking all them questions

[carmine sierra]

anyone know what's wrong with this

[polar acorn]

You say what's wrong, we try to find out why's wrong

[carmine sierra]

so it looks right?

[polar acorn]

What is the problem

[carmine sierra]

your right mb

forgot to mention one sec

[cosmic dagger]

you should be telling us what the problem is, not us guessing . . .

[carmine sierra]

Object reference not set to an instance of an object
ColliderChecker.OnTriggerEnter2D (UnityEngine.Collider2D otherCollider) (at Assets/ColliderChecker.cs:30)

[polar acorn]

What is line 30

[carmine sierra]

Line 30 is the if statement

[cosmic dagger]

we have no line numbers. post the actual error message . . .

[cosmic dagger]

there are two if statements, c'mon . . . 🤦‍♀️

[polar acorn]

Where do you create the list overlappingColliders

[carmine sierra]

the one i highlighted

but fair enough

[carmine sierra]

the top line i highlighted

[polar acorn]

That's where you declare the variable. Where do you create the list

[cosmic dagger]

i don't see either highlighted . . .

[carmine sierra]

oh okay cool, assumed it was fine since there were no red lines

but yeah i thought the list had to be made first

[cosmic dagger]

start over. post link of the !code so we can see the actual lines . . .

It's not a syntax error to create a blank variable you intend to fill in later. The error comes from trying to use it before filling it in

[carmine sierra]

yeah

[tacit birch]

still need help with this D: I can also stream to make things easier

[vale karma]

bro learning a new concept is so draining.. I wanted one lil mechanism and now i see the new terms 'delegates, action, func, and like 8 different ways to write a lambda

[carmine sierra]

do box colliders need to be on the same layer or z position to interact (unity 2d)

[cosmic dagger]

on, as long as the layers can interact with each other. can't remember about the z position, but just keep at the default 0 . . .

[carmine sierra]

the line renderer spawns only at negative z for some reason

[teal viper]

Can you record a video demonstrating the issue, showing the objects that you expect to collide?

[tacit birch]

sure

[teal viper]

Can you enable gizmos so that we see the colliders?

[carmine sierra]

how can I check in an if statement if one list contains any items in another list

[cosmic dagger]

you need to loop through the first (one) list and check if the current element is contained within the second (another) list . . .

[teal viper]

Okay. Can you print something in OnCollisionEnter2d instead and see if it prints?

[carmine sierra]

sorry im quite new to this but instead of doing if (list1.Contains(list2)), how would I use a loop to help

[tacit birch]

Tried, nothing printed

Code:

    private void OnCollisionEnter2D(Collision2D collision)
    {
        Debug.Log("Collision detected with: " + collision.gameObject.name);
        if (collision.gameObject.CompareTag("Enemy"))
        {
            EnemyManager enemyManager = collision.gameObject.GetComponent<EnemyManager>();
            if (enemyManager != null)
            {
                // Calculate damage and critical hit status using PlayerManager methods
                int calculatedDamage = (int)playerManager.Damage();
                bool isCriticalHit = (bool)playerManager.Critical();

                // Call the TakeDamage method on the enemyManager
                enemyManager.TakeDamage(playerManager, calculatedDamage, isCriticalHit); // Adjust parameters as needed
            }

            // Destroy the projectile after damaging the enemy
            Destroy(gameObject);
        }
    }

[polar acorn]

If nothing printed, a collision never occurs with this object

[tacit birch]

yeah that's what i'm trying to figure out

[polar acorn]

The Three Commandments of OnCollisionEnter2D:

1. Thou Shalt have a 2D Collider on each object
2. Thou Shalt not tick isTrigger on either
3. Thou Shalt have a 2D Rigidbody on at least one of them

[tacit birch]

Thou has followed all 3 Commandments and it still doesn't work

[polar acorn]

Show the inspectors of both objects

[tacit birch]

Projectile:

Enemy:

[teal viper]

Is the enemy parented to a UI canvas..?

[cosmic dagger]

well, first, you need to create a for loop to iterate through each element of the first list . . .

[tacit birch]

no, it's parented onto a different Canvas

[cosmic dagger]

wait, they're on a Canvas?

[teal viper]

Wdym by "a different canvas"?

[polar acorn]

wait why are they parented to any canvases if they're physics objects

[teal viper]

Is it a UI canvas component?

[cosmic dagger]

colliders are for actual GameObjects, not UI . . .

[carmine sierra]

thanks ill try that, where would that go though?

[tacit birch]

I took it off of the Canvas and it still doesn't work

[cosmic dagger]

any coding website, google, or youtube to learn about for loops. you'll need c# basics to get any of this done . . .

[carmine sierra]

alr thanks

[teal viper]

Take a screenshot of the whole inspector of enemy when it's in the hierarchy root
