[lunar quiver]

so what do i do?

[compact knoll]

set up your camera correctly like this ^

[lunar quiver]

hold up

now it works

unity is just like SFM

but the only difference is that its updated constantly

i am confused and surprised at the same time

how do i slow down my sprite?

[compact knoll]

you reduce its velocity

[lunar quiver]

where do i find that?

[compact knoll]

in the script where you set its velocity

[lunar quiver]

ok

anyone know why TMP_Dropdown would do this?

[brittle smelt]

Can someone help me diagnose what's wrong in this line

it displayed this error

[hollow crown]

https://help.vertx.xyz/?page=programming/common-errors/runtime-exceptions/null-reference-exception

In your case either dummyPlacement or hoverTile is the issue.
Also, if you're not getting autocomplete in your IDE, configure it using the instructions in #854851968446365696 (just saying this because of the little highlighting that code seems to have)

[sly shore]

hey does anyone know how to add physic material 2d when i go to create to add it i dont see it just reg physics material

[desert cargo]

They both use the same config type

oh wait, I'm wrong there... mb

it's there for me:

[still tendon]

Umm

I wanna learn how to make tilesets

I use GraphicsGale

but i dont know how to Import them into Unity

ao

so*

I rlly need help

[mossy fossil]

hi

is it possible to render certain bones in character rig on higher layer then the rest?

so the red hand is on top of the thompson

[turbid heart]

not sure.. but have you tried with the sorting layers/order in layer?

[mossy fossil]

the bone itself does not have it

[turbid heart]

i'm.. confused. can you show the hierarchy of your character?

[golden leaf]

what is the more optimal way to make a 2d multiple-leveled (as in height) tilemap game? I have 7 different tilemaps for each level and its not really practical to duplicate all of them for all the levels, not sure how many levels i need but it shd be a lot

[sly shore]

i figured it out its cuz i am using a new version so i have to go through 2d to access it

[gloomy lagoon]

Hi, could be that I'm just stupid but I am following a tutorial and I did it the exact same as the guy making it and nobody in the comment mentioned my error. And I am so unexperienced I don't even know what the error means.

second one is the tutorial

[golden leaf]

you need the CodeMonkey libraries?

it shd be in the desc of his vids

[gloomy lagoon]

oh, never watched another of his vids and now I tried to get what lambda expressions are for nearly 40 minutes

thanks xd

[jolly narwhal]

also you didn't do the exact same thing

the first 3 lines are different

[compact knoll]

You should probably try to stay away from the code monkey videos unless you enjoy learning to rely on someone else's code constantly instead of learning how to do things yourself

[golden leaf]

yeah code monkey uses lots of external libraries

[gloomy lagoon]

got it

[glad wagon]

hi my code at the moment spawns the enemy prefab (triangle) constantly because im calling the method in void Update() does anyone know how i can implement a float variable to adjust the rate in which they spawn im sure id have to use Time.deltaTime aswell

[dusky wagon]

@glad wagon what exactly are you trying to achieve?

[unborn sundial]

Instead of calling it in Update, you can use InvokeRepeating() in Start() to setup a function to be called every t seconds, for any time you want

The more professional way of doing this is starting a coroutine, using StartCoroutine()

you should run through the unity coding tutorials so you get all of this

https://learn.unity.com/

[glad wagon]

its allgood i ended up working it out

[feral parcel]

hi

uhmm can i ask?

[dusky wagon]

sure just ask your question @feral parcel

[feral parcel]

so how can i load prefabs for something like a skin selector?

because what i can do is only load sprites and i cant animate them...

[glad wagon]

hi does anyone know how i can get my prefab that spawns randomly to move across the screen to the other side? at the moment i have 4 cases, so randomly it will choose a side eg. case 1 then it will spawn a triangle randomly on the right side just outside of the screen. Now all i need to do is everytime it spawns on the right side it should move across the screen to a random point on the left. how exactly can i do this in 2D?

[turbid heart]

hello, dont cross post #📖┃code-of-conduct . i already answered you in #💻┃code-beginner .I see you're still stuck on the same issue

[sharp fox]

Wazzup! Pls can somebody help me? My scene switch doesnt work. Here's a code:

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

public class SceneSwitch : MonoBehaviour
{
    public string sceneToLoad;

    public void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("Player"))
        {
            SceneManager.LoadScene(sceneToLoad);
        }
    }
}

[turbid heart]

put a Debug.Log in the OnTriggerEnter2D and see if it actually gets called. another one in the if statement to see if it actually detects the object with the "Player" tag

[sharp fox]

i'ill try it thx

[abstract stirrup]

Hello!
I was wondering why my layermask does not work.
I have a groundcheck for my jump function but i cant get the ground check to work 😦

    [SerializeField] private LayerMask Ground;

    private bool IsGrounded()
    {
        Vector2 topLeftPoint = transform.position;
        topLeftPoint.x -= col.bounds.extents.x;
        topLeftPoint.y += col.bounds.extents.y;

        Vector2 bottomRightPoint = transform.position;
        bottomRightPoint.x += col.bounds.extents.x;
        bottomRightPoint.y -= col.bounds.extents.y;


        return Physics2D.OverlapArea(topLeftPoint, bottomRightPoint, Ground);
    }

    private void Jump()
    {
        Debug.Log("Jump start");
        if (IsGrounded())
        {
            Debug.Log("Is Grounded");
            rb.AddForce(new Vector2(0, jumpSpeed), ForceMode2D.Impulse);
        }
        Debug.Log("Jump stop");
    }

I get both jump debugs but not the is grounded one.
It only works if i set the player to the ground layer

[turbid heart]

If the issue is the OnTrigger not calling, there’s a debugging guide pinned in #💻┃code-beginner

[lament barn]

heya, is it possible to make a tilemap with a light in each tile?

i want to make a tilemap with the usual glowing mushrooms and i was wondering if i have to place all the lights down manually or not

[covert whale]

yeah u can draw with prefabs so just make a prefab with a light and this video can help
https://www.youtube.com/watch?v=UqhK6GpCgrM

[lament barn]

oh wow didnt know that tool existed

thanks a lot mate

[wispy hazel]

Hey I need help, for some reason when I jump while running into a wall I jump higher
this is the height of my normal jump

this is my height while running into a wall

    // Update is called once per frame
    void Update()
    {
        if (Input.GetButtonDown("Jump") && extraJumpTimes > 0)
        {
            anim.SetTrigger("takeOff");
            rb.velocity = Vector2.up * pJumpSpeed;
            extraJumpTimes--;
        }
    }

    //updates at a fixed time
    void FixedUpdate()
    {
        isGrounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, whatIsGround);
        xAxisInput = Input.GetAxis("Horizontal");
        rb.velocity = new Vector2(xAxisInput * pSpeed, rb.velocity.y);
        if ((facingRight == false && xAxisInput > 0) ||
            (facingRight == true && xAxisInput < 0))
        {
            Flip();
        }
        if (xAxisInput == 0)
        {
            anim.SetBool("isRunning", false);
        }
        else
        {
            anim.SetBool("isRunning", true);
        }

        if (isGrounded == true)
        {
            extraJumpTimes = extraJumpsAmnt;
            anim.SetBool("isFalling", false);
        }
        else
        {
            anim.SetBool("isFalling", true);
            if (rb.velocity.y < 0)
            {
                rb.velocity += Vector2.up * Physics2D.gravity.y * fallMultiplier;
            }
            else if (rb.velocity.y > 0 && !Input.GetButton("Jump"))
            {
                rb.velocity += Vector2.up * Physics2D.gravity.y * lowFallMultiplier;
            }
        }
    }

this is my code that is command of player movement

[celest elbow]

okay, so like 90% of inexplicable problemos can be fixed by moving physics calcs into fixedUpdate

so set a bool for "isJumping" or something of the sort

set it to true when you get the jump input

then check for isJumping in FixedUpdate()

if isJumping is true then set the rigidbody's velocity and set isJumping back to false

[desert cargo]

GetButton happens to work reliably in FixedUpdate

It's only GetButtonDown and GetButtonUp that are broken

GetAxis is also okay in FixedUpdate

[celest elbow]

yes

the issue is not that they are checking for those

the issue is that they are doing rigidbody calculations outside fixedupdate

[rich iron]

When I get the texture of a Sprite in my sprite sheet, the texture is of the entire sprite sheet not just the single sprite from it. How can I just get the texture for the sprite's rect?

[vague meadow]

any guides on z-tilting that someone can point me to?

[alpine pumice]

why not use the orderby system instead?

oh, sorry. tilting.

i read "tiling"

[young mauve]

I hope this is the right channel to ask this, I'm returning to Unity after a long while away, looking to continue making 2d projects.

When I last used Unity you were better off using 2D Toolkit or ex2D to 2D done. I understand 2D in Unity is a lot better now, so are there still handy libraries to help with 2D or is Unity standard okay to use?

[still tendon]

anyone knows why my sprite color doesnt change anymore? It worked before I added the second IEnumerator but not anymore.. I tried commenting it out and still doesnt work

[elder minnow]

Does it get called? Did you accidentally change Gametimer? What value is TimerSpeed? Those are likely the source of your issue

[still tendon]

that was the issue, fixed it, thanks! 😄

[still tendon]

had deleted GameTimer on accident earlier

[still tendon]

im making endless runner 2d game and i have a border to despawn the obstacles and it wont work i have followed a tutortial and i do not know what to do

[compact knoll]

you need to be way more specific than "it wont work"

[still tendon]

when it hits the border nothing happens it stays there

i have tags setup and box colliders

[compact knoll]

show the code you are using to destroy the obstacles

use a paste site to share code. #854851968446365696 has some links

[still tendon]

https://gdl.space/raw/uyevabaget

[compact knoll]

don't compare tags that way, use collision.CompareTag("TagGoesHere")

also do either of the objects have a rigidbody on them? if not, that's required

[still tendon]

they do

[compact knoll]

great! are your borders correctly tagged? also make sure to make that change i suggested, it throws actual errors if you did something wrong instead of just returning false with no error

[still tendon]

now they get stuck on the wall which is better than phasing through it but still do not delete themselves

[compact knoll]

just to make sure, your obstacles do have that script attached, you switched to CompareTag, and your borders are tagged with the tag you are checking for in your collision, right?

[still tendon]

i tried to do compare tag and i got a error im on 2019 unity which could be the problem

[compact knoll]

what was the error

[still tendon]

do i still keep the if

[compact knoll]

yes, you just change collision.tag == "whatever" to collision.CompareTag("whatever")

[still tendon]

Assets\Script\Obstacle.cs(15,12): error CS1003: Syntax error, '(' expected

[compact knoll]

since i cannot see the code you wrote, i cannot tell you what you did wrong, but it sounds like you may have removed the () for the if statement

[still tendon]

https://gdl.space/raw/sacipizoku

[compact knoll]

you removed the () for the if statement

that should also have been underlined in your IDE. are you using Visual Studio?

[still tendon]

yes i am on old version tho

[compact knoll]

it doesn't matter if you are using a 2019 version, it should still do that. Before you do anything else, go configure your IDE using the steps linked in #854851968446365696

[still tendon]

it is still phasing through the border

[compact knoll]

show a screenshot of an obstacle in the inspector and one of the border in the inspector

[still tendon]

ok

[hollow crown]

"OntriggerEnter2D" is incorrect.

[still tendon]

what do i do to fix it?

[hollow crown]

https://help.vertx.xyz/?page=programming/physics-messages

[compact knoll]

god i always miss the capitalization errors, thanks vertx

[compact knoll]

it should be OnTriggerEnter2D

[still tendon]

it worked thank god

thank you for helping mme

[compact knoll]

if you haven't already, set up your IDE so you get autocomplete and don't make that mistake again

[still tendon]

alright

[still tendon]

having another error Assets\Script\ScoreManager.cs(4,6): error CS1001: Identifier expected https://gdl.space/raw/budahakasu

[hollow crown]

using.UnityEngine.UI;

The error said: ScoreManager.cs(4,6), Ie. That file, line 4, column 6.

It should also be underlined in red in your IDE. If that's not the case you need to configure it properly using the instructions in #854851968446365696

[still tendon]

what do i do tho i dont see whats wrong

[hollow crown]

First configure your IDE if that's not been done

then compare that line to the other using statements you have. It's not hard to spot what's different

[still tendon]

thank you i didnt see the period im dumb

[hollow agate]

So I am making a jump king game has my semester project. I don't know how to make the camera go higher when I hit a certain point in the screen like Jump King
https://www.youtube.com/watch?v=9_W-3lAljes : 0:15

[unborn sundial]

@hollow agate just move the camera object

[hollow agate]

But how do I limit a zone?

Like how can I say at this height, move the camera

[unborn sundial]

In the simplest case, you could just do if (playerY > cutoffHeight) move camera up, and vice versa for < cutOffHeight

but more generally, you could take the player's position and round it to a grid, and use that as the center of the camera

[hollow agate]

Oh maybe I can use a raycast

Not the best but I can delimit the zone how I want

[glad wagon]

anyone know how i can fix this error im trying to implement code so that the enemies that spawn and move actually face the direction/point theyre moving to ```cs
[SerializeField]
private float rotationSpeed;

if (direction != Vector3.zero)
{
Quaternion toRotation = Quaternion.LookRotation(Vector3.forward, direction);
transform.rotation = Quaternion.RotateTowards(transform.rotation, toRotation, rotationSpeed * Time.deltaTime);
}```

[celest elbow]

show me where you defined direction?

[remote kettle]

Hey is there any useful c# tutorial for unity in yt? I know almost nothing atm, so a begginers one is what i'm looking for.

[turbid heart]

there's the one in Unity Learn. Beginner scripting. pinned in #💻┃code-beginner
There's also an intro to c# one if you're new to C# itself

[jolly narwhal]

there's also a search feature in Youtube: https://www.youtube.com/results?search_query=beginners+c%23+tutorial+for+unity

[remote kettle]

Thanks I'll check these

[prisma ocean]

so uh, there are lines between the tiles and the character seems to vibrate when moving lol

[prisma ocean]

also is this bad for setting the rotation of an object? I want to set the player's rotation to the rotation of a chair sprite, but the player just continues rotating

ah, used eulerAngles instead. Why does that happen? lol

[slim girder]

I'm getting a weird bug where my player gets stuck inside an enemy, short video footage included. I handle collision checks for both the player and enemies the same way using Physics2D.BoxCastAll as shown here: https://paste.ofcode.org/5QuEvS6VHBmnnwpNHkmzfx, I don't have any problems with collision between the player and other things like walls, only enemies that use the same collision check script as the player. Curiously, if I get rid of the BoxCastAll stuff on the player but keep it on enemies, and put a RigidBody2D on the player and handle collision like that instead, the bug goes away, but I don't want to use a rigidbody. Does anyone know why this bug might be happening?

[prisma ocean]

Say I had a space ship that was made of some sprites and some tilemaps, all children of a parent "ship object" that has a rigidbody. I'm currently trying to get rb.AddForce() to work to move the ship. It moves everything except the tilemaps. Can I get it to work with the tilemaps?

[stuck dune]

I am quite new to game dev, and I need help with some C# death scripts, any1 up for helping me? (the script is very small)

[prisma ocean]

fixed: changed children body types to kinematic

[compact knoll]

You need to be more specific about what you need help with

[stuck dune]

Currently I am having issues with a death-script. It resets my scene if no input is detected over and over as if it's on a loop, and I have no idea how that happend

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

public class PlayerLife : MonoBehaviour
{

    private Rigidbody2D rb;
    private Animator anim;

    // Start is called before the first frame update
    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        anim = GetComponent<Animator>();
    }

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Trap"))
        {
            Die();
        }
    }

    private void Die()
    {
        rb.bodyType = RigidbodyType2D.Static;
        anim.SetTrigger("death");
    }

    private void RestartLevel()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().name);
    }
}

there it is

and as soon as I assign it to player the level resets on a 2 or so second interval if no input is detected

i've set it up to restart after the death animation, but even without this event it just restarts

[compact knoll]

Where is RestartLevel() being called?

[stuck dune]

idk, nowhere I can find

only at the end of the death animation event

but if I remove it, it still resets

[compact knoll]

Make sure your animation isn't set to loop. But if the reset is still happening even without the animation, then something else is resetting the level

[stuck dune]

yea the animation isn't looping, it isn't even triggered

and I know it's this script because when I remove it, it stops

[compact knoll]

Well it's not being called from the script directly, unless you didn't share the whole thing.

[stuck dune]

found out through an error message that it has something to do with my idle animation somehow

even if it isn't even connected

[narrow shadow]

i have a simple question i have this class that i instantiate runtime, how do i add a collider2D to it through code, i tried answering this question myself but failed, can some kind person spoonfeed me ?

[turbid heart]

Is there a reason why the prefab doesn’t have a collider by default?

[turbid heart]

Also, gameObject is not a type. It is GameObject. You should have an error. And if you’re not seeing red underlines in your code, you really need to configure your IDE. Instructions are in #854851968446365696

Also, you’re probably not searching up the right things. Look up “how to add component in script unity”

But configure your IDE first. That’s important

[narrow shadow]

i searched for the gameObject.AddComponent() method but uh

its confusing to use

[turbid heart]

What do you not understand

[narrow shadow]

i thought

so

[turbid heart]

Also please address those issues i pointed out

Why not just add the collider to the prefab in the inspector

[narrow shadow]

tiroprefab is a gameobject so it must have this addcomponent method, and i must pass the class i want to add as a parameter

but it is not like that

like

tiroprefab.AddComponent(Collider2D)

[turbid heart]

You clearly did not read the documentation

You don’t pass in types using (), you use <>

I don’t think you can add Collider2D either. You need to be specific on the collider type. A configured IDE would suggest valid options.

[narrow shadow]

ok, i will configure my IDE

[turbid heart]

And fix that gameObject type. That’s wrong

[narrow shadow]

i mean it was working but i will change

[turbid heart]

This. Will not work. gameObject is not a type

[narrow shadow]

i can instantiate tiroprefab in runtime without errors

[lethal niche]

AddComponent()?

Probably better off adding the component on start and flipping the trigger when needed if that's what you're aiming for.

[snow willow]

It's GameObject not gameObject

[brittle smelt]

How do i fix when a ui become bigger when maximized?

[snow willow]

Familiarize yourself with https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/UIBasicLayout.html and the CanvasScaler component

[small berry]

so im having a super weird bug i guess, when i export my game to itch io for some reason the character like shakes back and forth when trying to look towards the mouse but this doesnt happen in unity at all. unity: https://streamable.com/qvs5ex itch.io: https://streamable.com/rc9ubd

[snow willow]

most likely an issue of code that behaves differently depending on the framerate or resolution of the game

[small berry]

i really cant find it heres my movement code https://hastebin.com/picelahepu.cpp

[celest elbow]

why is your code in c++

[small berry]

i dont know man

hatebin doesnt work for some reason for me

[unborn sundial]

@small berry Is your camera moving? Since you calculate the mouse position relative to the camera position, there might be some desync there

[small berry]

i fixed it it was because "mousePos = cam.ScreenToWorldPoint(Input.mousePosition);" was in void update and not fixed update.

thanks though :))

[small berry]

nvm the bug is still there on some computers :))

[small berry]

how would i go about fixing it?

[unborn sundial]

well assuming that's the problem, you need to calculate and store mousePos before the camera moves

this would best be done in the script that moves the camera

and then other scripts can pull the mouse position from that

(the Vector3 position)

[small berry]

im pretty new to coding and im using an asset for the moving of the camera

[unborn sundial]

which asset?

[small berry]

cinemachine virtual camera

[unborn sundial]

Maybe try changing the Cinemachine's "Update Method" to LateUpdate ?

it looks like an option in the inspector

[small berry]

not fixed update?

[unborn sundial]

and then compute mousePos in Update

if it was in FixedUpdate, it would run with unpredictable order relative to other FixedUpdate

the goal is to get it so that it moves the camera after you've calculated and stored mousePos

and not interweaved

[small berry]

i'll try it out :))

[small berry]

its still a little bit left but it seems like its mostly gone thanks :))

[young mauve]

I am trying to think how to make a side-scroller beat-em up, similar to Double Dragon. What method could be used to keep a player object within the walk-able space (highlighted orange on the image)?

Could a Sprite Shape be used to create the area and then a Collider OnTriggerExit be used? Just trying to figure out options and techniques at this point, not after a coding solution quite yet 😛 Cheers!

[lament spire]

just put colliders on the feet of the characters and block out the base of the buildings with colliders

[snow willow]

could just use 3D physics and an orthographic camera

[worn venture]

mouseposition to worldtocell is not giving me the correct tile, how do i find the offset?

[snow willow]

mouse position is in screen space and world to cell expects a world space position. So you'd have to convert your mouse position to a world position somehow

if it's 2D with an orthographic camera generally it's pretty safe to do that with Camera.ScreenToWorldPoint

otherwise you should generally use Camera.ScreenPointToRay and Plane.Raycast

[worn venture]

thank you. i have worldtocell using screentoworldpoint , but its not exactly accurate . is there a way i can have it visualize which cell im on for debugging purposes?

[snow willow]

Vector3Int cellCoordinate = whatever;
Vector3 world = grid.CellToWorld(cellCoordinate);
Debug.DrawLine(world + Vector3.down, world + Vector3.up, Color.green);
Debug.DrawLine(world + Vector3.left, world + Vector3.right, Color.green);```

something like that perhaps?

[worn venture]

thanks that works, yeah the cell selection is way off

[snow willow]

are you using a perspective camera?

[worn venture]

ortho

[peak idol]

Hey, I am working on a 2D game but I m having some problems. I want to keep the player in the red square the black square being the screen. I got this working but whenever I size the screen diffrently it doesnt work because the red square doesnt size with it. Whats the best way of handling such thing?

Like do I use screen bounds or camera coords

[turbid heart]

is the red square UI?

[turbid heart]

you can use either one, really. it's just a question of screen or viewport ratio, isn't it?

[peak idol]

those are the bounds

[peak idol]

but either are possible, having issues with the coordinate system of unity an mouse location to work together

[turbid heart]

if you're using mouse location, you should just use screen since mouse uses screen coordinates

[peak idol]

and then calculate the bounds from that

[turbid heart]

how are you defining your bounds right now?

[peak idol]

hardcoded values

[turbid heart]

okay, and you've based your hardcoded values on a specific screen size now right?

[peak idol]

yes

[turbid heart]

you can do
hardCodedWidth * newScreenWidth/oldScreenWidth, i think

that'll give you the new width in proportion with your new screen width

[peak idol]

oh ok thats a lot easier then what I was trying

🙂

[turbid heart]

does it.. make sense to you?

[peak idol]

it does I just need to clean my code and make sure I get these values on the correct places 🙂

[turbid heart]

glad to have helped ^^ all the best

[peak idol]

thx

[lunar sedge]

https://www.reddit.com/r/Unity2D/comments/po42r9/destroying_an_object_after_it_leaves_the_screen/?

Anyone able to help me here?

[scenic hatch]

when i set a public enum's state in one script it changes is for all the scripts that reference it right?

[snow willow]

you need to think about instances of the script, not the script itself

if you change a field on a particular instance of the script, it changes on that instance. Anything that references that instance will see that change

any code that starts public enum is an enum type declaration, not a field. It has no state.

[snow willow]

if that confused you - your script defines a class (hence the public class at the top).
A class is like a blueprint for a house.
An instance of the class is an actual house

When you attach your script to a GameObject in the scene, you create that actual house from the blueprint

each house has its own copies of all the fields on it

[scenic hatch]

oooh i see

[snow willow]

e.g. ```cs
public int myField;

[scenic hatch]

i see i see

thank you so much man! 😁

[sly brook]

so i was following this tutorial and at the end i got this error CS0029 how would i fix this

like that ?

error is myAnim = GetComponent<Animator>();

[distant loom]

Got a small question. If I load a local picture, how can I cache it? so that next time I load it from the cache and not from the disk.

[sly brook]

it says
Cannot implicitly convert type 'UnityEngine.Animator' to 'UnityEngine.Animation'

[late viper]

you're trying to assign an Animator to an Animation

[sly brook]

yes

[late viper]

you can't, they're different types

which one do you actually want

[sly brook]

uuuuh

il try somthing and then il come back if it doesnt work

[amber hinge]

im trying to make this island go up and down but any float value i enter makes it negative

if you see unneccasary print statements that just to give me a better understanding of whats going on

[ancient path]

do you want it to go up and down?

like a coin?

like floating?

[amber hinge]

yeah go up to the spotr then when it hits it go down then over again

[ancient path]

try sine waves

brackeys did a tutorial about that

maybe it can help

[coral dock]

dunno if this would go in code or animation but how would i go about having an animation play on key press wasd

the new input system is weird

[coral dock]

what does this mean

[ancient path]

you cant use that because you are using the new input system

i think

[coral dock]

i switched it back to the old

maybe i need to restart the project

[abstract olive]

You can change it to use both in the player settings.

[coral dock]

i changed it to old

why does my character only go back and forth

no errors

[compact knoll]

Both of those are setting movement.x, you need the vertical to be movement.y

Helloo

[snow willow]

open your animation clip

[faint hollow]

Someone can give a hand to fix this pls

[snow willow]

go to the animation event

and fix it

if you don't know what an animation event is, you probably added one by accident, and you can just delete it

This is what animation events look like in the animation clip

Yeaaah

was that

Ahh was hoping for sth better nvm

[north torrent]

I'm having a weird problem with my game's render order. The order between NPC sprites and the UI elements for dialogue is sometimes wrong. In the first case, the sprites hop on top of the dialogue box once the reply buttons appear, but hop back underneath it once the reply is given and the buttons are hidden.

Both the dialogue box and reply buttons are UI elements and I hide and show them from the script by disabling or enabling their GameObjects. The reply buttons are shown by a coroutine that renders the buttons once the writing animation on the dialogue box is finished.

In the second case, the pink bunny is just on top of the dialogue box all the time. I don't know what makes it different since it was copied directly from the other bunnies and should have the same settings.

Is there a way for me to make all the UI elements be on top of all sprites since that's what I want anyway? I couldn't find where I could assign a sorting layer for them.

Oh, okay. It's on the Canvas element. That solves this problem visually but I still wonder what would have led to this error.

[worthy stump]

Hi folks, is there a way for me to get access to a sprite's atlas in c#?

There appear to be exposed methods for working with Atlases in c#, as detailed here (https://docs.unity3d.com/ScriptReference/U2D.SpriteAtlas.html) but I can't find out how to actually get a reference to the atlas that my sprite is using. I can get access to the texture, but not the Atlas object itself. Any ideas?

[covert whale]

what render mode is your canvas in? if it's in overlay then it will always be on top, if it's in camera space then it renders depending on the layer and world space depends on position

[north torrent]

It was in Screen Space - Camera. Putting it to Overlay seems to hide it from the editor, though.

[covert whale]

it's usually not hidden but much larger

try zooming out

[north torrent]

Oh there it is. I do think I'm happy with camera space and a sorting layer though.

[covert whale]

if it's in camera space and isn't always on top then make sure ur camera is assigned and that it's on the UI layer or whatever layer is above everything else

[late viper]

isn't is just this https://docs.unity3d.com/ScriptReference/Sprite-texture.html

Get the reference to the used texture. If packed this will point to the atlas, if not packed will point to the source sprite.

[worthy stump]

No, that returns a Texture2D, I need the SpriteAtlas class

And you can not cast T2D to SA

[fierce pivot]

anyone know how to add more tile in tile pallet for 2d

[wide lagoon]

Is it impossible to change a sprite's frustum culling bounds?

[onyx sequoia]

So Sprite Shapes only render when they're completely in the camera viewport, is there a way to turn that off so that they always render even when they're not completely on screen? I'm having trouble now because they do not appear, as they are quite large and only slowly come into view, so they start out as invisible (along with their colliders not working)

it works fine in the editor but not in the build

[wide lagoon]

Is there a way to access the underlying mesh for a sprite?

[still tendon]

this is kind of my first time making a UI for my "retry game" system and for now im trying to test the UI by making it appear on my screen after the player dies but for some reason, the UI doesn't appear on my screen even after the player dies. Here is the code:
i used two scripts for it
this is the game manager

    public GameOver gameOver;
    public TextMeshProUGUI scoreUI;
    public TextMeshProUGUI highScoreUI;
    int score = 0;

    // Start is called before the first frame update
    void Start()
    {
        scoreUI.text = PlayerPrefs.GetInt("Score", score).ToString();
        highScoreUI.text = PlayerPrefs.GetInt("HighScore", score).ToString(); 
    }

    public void Scored()
    {
        score++;
        scoreUI.text = PlayerPrefs.GetInt("Score", score).ToString();

        if (score > PlayerPrefs.GetInt("HighScore", 0))
        {
            PlayerPrefs.SetInt("HighScore", score);
            highScoreUI.text = score.ToString();
        }
    }

    public void ResetScore()
    {
        PlayerPrefs.DeleteKey("HighScore");
        highScoreUI.text = "0";
    }

    public void GameOver()
    {
        if (player.playerDied == true)
        {
            gameOver.Setup(score);
        }```
and this is the GameOver script
 ```public Text highScoreText;

    public void Setup(int score)
    {
        gameObject.SetActive(true);
        highScoreText.text = score.ToString() + " Points";
    }```

is there any fix to my problem?
i was following a tutorial by the way and it wasnt working for some reason

Hey! I'm creating a topdown shooter game and I've created enemies that chase the player the issue however is that I put a rigidbody2d on them and if I set the body type to "Dynamic" the don't overlap BUT they drift off aimlessly, if I switch it to Kinematic they don't drift off aimlessly, but the overlap. is there some setting or something I need to change?

[coral dock]

so i have this so whenever i left click it plays an animation/shoots how would i go about looping it so i only have to hold down left click (automatic)

https://cdn.discordapp.com/attachments/497874004401586176/887827437096931348/unknown.png

i tried removing "down" from Input.GetMouseButtonDown but yes it does make it automatic there is no cool down so the gun shot sounds like a swarm of bees instead of an smg

[snow willow]

yep you need to add a cooldown

put all the shoot stuff into a separate function, then use a timer variable to create a cooldown

[covert whale]

how are you setting the movement of the player and enemies?

can you show what drifting off aimlessly looks like

A Kinematic Rigidbody 2D does not collide with other Kinematic Rigidbody 2Ds or with Static Rigidbody 2Ds; it only collides with Dynamic Rigidbody 2Ds.
from the docs https://docs.unity3d.com/Manual/class-Rigidbody2D.html

my recommendation is to set them to dynamic and check things like if there is any gravity, friction or if the force u've applied to them causes that drifting

then if that doesn't eliminate the drifting then set it to kinematic and do collisions manually

you can use raycasts or overlaps or anything else

[muted magnet]

(I'm not sure its the right place to ask it)
I'm watching a tutorial where the dude create a 2d object, specifically a square

While it seems that my version can't

[compact knoll]

the square is just a sprite using a default square sprite. but also make sure you have all of the relevant 2d packages installed in the package manager

[muted magnet]

so i assigned a random spire but now when i generate a grid it is ugly

[muted magnet]

Can you tell me more plz ?

[compact knoll]

Window > Package Manager, select Unity Registry and make sure you have the 2d packages installed

[muted magnet]

so do i just import the non-checked ones ?

[turbid garden]

I dont know if anyone can help me but i have this issue that i am trying to solve.
Basically i have 2 SpriteRenderer ontop of eachother with different Mask interaction. One is set to visible outside mask and the other one to visible inside mask. When i drag my objects over the mask one gets rendered and the other one doesnt like the mask interation have been set. The probleme is that i have the Sprite Mask on a different Rendering Layer Mask so it doesnt interact with these SpriteRenderers but it does anyways.

[subtle vessel]

did you set the masking layer range on the sprite mask? https://docs.unity3d.com/Manual/class-SpriteMask.html

[celest ferry]

Can I switch between the languages used in the localization package through my own code?

{Hope you understood what I mean}

[tame turret]

yes, for example by assigning the selected locale like so: LocalisationSettings.SelectedLocale = myLocale;

[vague meadow]

has anyone here setup aabb collision on their 2d game instead of using unity colliders?

[ancient path]

Don’t worry I already helped him

[austere seal]

I can't get two objects to produce a trigger, but I made sure to add collider2Ds to both with one having trigger checked on as well as a rigidbody2d to one of them. I also made sure I was using the correct function name in my script for OnTriggerEnter2D, but I tried using that function to output a string to the debug log and it does nothing. I'm not sure what I'm doing wrong, everything I see online assumes the problem is that there isn't a rigidbody2d but that's not the case here.

[ancient path]

Can you show a vid

[austere seal]

I think I figured out the problem actually, I need to pay more attention to what I type

I spelled Collider2D wrong

wow I can't believe I've spent hours trying to fix this and it was just a typo

[turbid heart]

do you have your IDE set up? that usually catches typos for you. you get red underlines, suggestions and auto complete. instructions are in #854851968446365696

[austere seal]

Yeah I haven't done that yet

[turbid heart]

yeah, should do it soon. could save you hours

[austere seal]

It caused the layout to change so I was confused at first but it does help

[knotty fog]

I have a grid system for pathfinding (A*) and it works like a charm
But now im working on a 2d Isometric game, and i need to change that grid system, but the edit should be pretty easy

basically i need to rotate it
and this is how i generate the first one

but really i can't think of a way of rotating it into the second one, i mean i have the idea but it doesn't work

[river night]

How would I make a trail like this? https://www.youtube.com/watch?v=Ilo4UpzKN_U

[late viper]

looks like a recording of his gameplay rotated in video editing software

or maybe even rotated in game

[river night]

It is rotated in game

I just don't know how to make a trail like this

[compact knoll]

trail renderer

[river night]

woah i didn't know that was a thing, I'll try it out

[granite plank]

hello i have a simple issue with my 2d game im trying to figure out how to check if an image is rotated right or left? and if the user is moving left or right it will switch the image. im not sure how to check with transform.rotation because then it asks about quaternions

i want to be able to check if gameObject.transform.rotation == Quaternion (0, 0, 0, 0); ??

[calm wyvern]

take a look at transform.eulerAngles
they are the unreal degress (0-360) that you see in the inspector

eulerAngles are the global rotation
localEulerAngles are the local rotation

[granite plank]

so how do i check if its left or right?

[calm wyvern]

just look how the values change for each direction then you can build a check of it

[granite plank]

i know how to check things i meant how do i check for the rotation at 0 and 180 degrees???

rotation isnt a vector its a quaternion so how do i check what way its facing with quaternions?

[compact knoll]

Euler angles are a Vector3

[river night]

try if (transform.rotation.eulerAngles.z == 180)

[calm wyvern]

is the roation value set exactly via code?
if not comparing floats directly can cause issues

[river night]

oh true

[compact knoll]

even if set via code floating point errors still exist

[river night]

I guess round it or smth

[compact knoll]

use Mathf.Approximately to compare floats

[slim cradle]

can I ask for help

[compact knoll]

https://dontasktoask.com/

[slim cradle]

oh

Is there a problem with my code?

how should I link the code here?

code block or the file itself

[compact knoll]

#854851968446365696 has instructions for posting code

[slim cradle]

https://paste.ofcode.org/jxtmrNhjHjKH25nhgNAVtT

basically I somehow can't set these 2

there is no error in the code or maybe I coded it wrong

[compact knoll]

What do you mean when you say you can't set them? Like are there no options in the dropdown, are the options you try selecting not working, etc

[slim cradle]

there are other options but then whatIsground and whatIsPlayer won't appear

[compact knoll]

You need to select the layers that represent ground and player in the dropdowns you arent selecting your variable name in there

[slim cradle]

its not appearing in the options

[compact knoll]

then you didn't create the layers

it isn't going to show your variables in there, it's showing you the list of available layers

[hollow crown]

Why have I seen two other people make this same mistake in the past week

but never in history before that

is there some new tutorial that's not making this clear

[slim cradle]

I based it from here

[hollow crown]

#archived-code-general message

[compact knoll]

weird

[slim cradle]

https://youtu.be/UjkSFoLxesw

[compact knoll]

ah looks like he doesn't bother showing how to create new layers to include those

[slim cradle]

yes I have the same exact problem as this

[compact knoll]

https://docs.unity3d.com/Manual/class-TagManager.html
add the layers

[hollow crown]

and it was resolved in that thread.

[slim cradle]

oh okay ty

[compact knoll]

then make sure your ground and stuff is set to the relevant layers

[slim cradle]

ah I see ty

the tutorial didnt bother teaching how to make layers

[compact knoll]

yeah that's the problem with a lot of those "how to do thing super quick" tutorials. they won't go over the basic stuff because they assume you know how to do it. You are better off going through some of the more in depth tutorials that actually teach you how (and more importantly why) to do things

[slim cradle]

uh the enemies are still spasming out of the playing field

[slim cradle]

is there a way to rewrite this code without navmesh?

but basically the same function

[compact knoll]

is this for 3d objects? because i just noticed you are using a 3d Rigidbody and i'm fairly sure that unity's navmesh doesn't work for 2d (unless it was changed at some point)

[slim cradle]

i am using a tank

2d

[compact knoll]

okay so you're doing 2d which means you need a Rigidbody2D rather than a Rigidbody, you would also need to completely rewrite it using some other pathfinding method (like A* or NavMeshPlus) or write your own pathfinding

[slim cradle]

the enemy behaves weirdly

[compact knoll]

okay that is definitely not 2d, mate.

[slim cradle]

i lack sleep srry

wait so what seems to be wrong with the code

idk why the enemy is sporatic

[compact knoll]

you should ask about non-2d code stuff in #💻┃code-beginner or #archived-code-general

[slim cradle]

oh

Hey guys, I am currently using rb.addForce(hSpeed, vSpeed) and I am wondering how exactly I would grab the force, and rotate it, without actually rotating the object (so using code) by degrees or so?

[toxic solstice]

Hello. I have a problem were the player can jump thrice sometimes instead of jumping twice (double jump). Can anyone help me identify the problem?

https://hastebin.com/eyuwoyokot.csharp

I tried to make the length of the rays shorter, but it didn't solve the problemm

I also checked the logic, and it seemed to be working just fine

[austere seal]

Will you be doing this from the same script or a separate one?

[coral tusk]

same

//[I may put the forced turning here]
//Goal: get difference from last rotation to current | add difference to current movement direction
Quaternion difference = lastSpriteRotation * Quaternion.Inverse(playerSprite.transform.rotation); //https://forum.unity.com/threads/get-the-difference-between-two-quaternions-and-add-it-to-another-quaternion.513187/
Quaternion velDir = Quaternion.Euler(rb.velocity.normalized);
Quaternion goalDirQ = difference * velDir;

Vector3 goalDir = goalDirQ.eulerAngles;

//Now to rotate this bad boy
//https://forum.unity.com/threads/change-velocity-direction-and-not-magnatude.368272/
Vector3 newVel = goalDir * rb.velocity.magnitude;
rb.velocity = newVel;

This is what I was trying

[vocal condor]

Verify if you're doing the first jump or second jump twice by printing in the if statements. There can be a number of reasons why this may be occurring. One is if isGrounded is true again. Either ways, eyeballing code isn't the appropriate way to debug. Best start logging variables to see the flow of the jump states.

[coral tusk]

don't think it's working probably due to the sprite rotating being kinda off anyway

My goal is to stay stuck to a wall, so I want to get the direction to the point underneath the player, and rotate velocity based on that

so getting the last dir to floor, and the new one, finding the difference and rotating the velocity based on the difference

Idk if that would even work

[austere seal]

I think all you'd have to do is add force in a new direction after chaning hSpeed and vSpeed

[coral tusk]

tis weird, I am using addforce(hSpeed, vSpeed) and that includes the gravity

and I am using this for movement

        //Get rotation of sprite from ground/collision position
        float rot = GetRotationToHit2D(playerBoarderHit).eulerAngles.z;
        rot *= Mathf.Deg2Rad;

        
        if (Mathf.Abs(h) > hDeadZone)   //If choosing to move, move in sideways direction relative to own rotation
        {
            hSpeed += (h * hMoveSpeed) * Mathf.Cos(rot)/2;
            vSpeed += (h * hMoveSpeed) * Mathf.Sin(rot)/2;
        }

[austere seal]

Did you change gravity for the rigidbody?

[coral tusk]

to 0

I am doing gravity myself

[austere seal]

I'm not sure why it would still be affected by gravity if you set it to 0 but you could try adding an equal force in the opposite direction

[coral tusk]

Oh I meant, I have gravity that continues to apply to the object regardless

Hecc this will get pretty confusing aye

[austere seal]

I don't quite understand what you mean

Can you show how you're doing your own gravity script

[coral tusk]

hspeed -= grav

which goes to
addforce(vspeed, hspeed)

[austere seal]

Oh yeah ok

[coral tusk]

I think I can find a good way to explain it one sec

[austere seal]

I understand now

[coral tusk]

Okay bouta send a clip

https://imgur.com/a/dvq8pPG

Okay so my problem is

I am trying to make it stick

but it keeps accelerating when it goes around a corner?

I know why

I have the character's sideways move += depending on the rotation of the ground below

but

to keep it on the block, I am adding a force directly towards the tiny pink lines (direction to the floor)

I am adding 20f in that direction, which is absurd, but it's to bring out the problem which is:

when the character goes around a corner, it keeps that force and adds it to it's current movement

I am wondering if there is a better way to do this?

the reason I am pressing the player into the object is to allow gravity to continue, but still have the object stick

[austere seal]

Have you tried adding an opposite force equal in magnitude to the previous force and then adding the new force?

As in, whenever the direction of the force necessary to keep the object stuck changes, negate the previous force and add the new one

[coral tusk]

Yeah I see what you mean, that is a good idea, I am a bit unsure how to implement it yet

This is how I add the force

            //Then apply push into wall
            float spd = 20f;
            hSpeed += spd * Mathf.Cos(rot)/2;
            vSpeed += spd * Mathf.Sin(rot)/2;

(adds in direction of small pink line which is what it's stuck to)

it adds to the hspeed and vspeed, so it's all a little mixed

Idk how to sort of seperate it

[austere seal]

I think you can just add two separate variables to store the previous speed

[coral tusk]

Since, when the OB hits a wall, hspeed pretty much goes back to 0

so when the character is pushed into the ground, Idk how much of the force dissapears...? if that makes sense?

[austere seal]

So is hSpeed relative to the object's rotation?

[coral tusk]

like I would assume I can push the character into the ground at 100f, but apparently not it's seeming

the object never actually rotates

only the sprite

it's a non-rotating circle collider

[austere seal]

Oh interesting

[coral tusk]

Yeah all the angled movements is using Trig :D

I'm making it quite difficult

[austere seal]

You're adding speed in Update or FixedUpdate right?

[coral tusk]

I know by reducing this, it won't gain so much speed, but I wanna get it so it always goes to the same height

Almost everything is in fixedupdate

except getting inputs and such

[austere seal]

So you're just adding force every frame?

[coral tusk]

yeah

so I am using addforce every frame

at the end of each frame it calculates hSpeed and vSpeed

[austere seal]

That's gonna multiply the force exponentially

[coral tusk]

I only ever ADD to hSpeed and vSpeed, which is how when the object collides with something, the speeds essentially reset

[austere seal]

Try making sure addForce only gets called if hSpeed and vSpeed change

[coral tusk]

yeah it changes every frame

as you can see when the object is sliding, it just slides at one speed

which is the goal

oh right

so fun facts:

I did this very interesting thing where

I get the difference between my last movement speed and the new one I am applying

and I only add the DIFFERENCE between the two, then add that to AddForce

which is how it isn't actually going out of control

Since I was using transform.position before, but that's how I converted it over to AddForce

[covert whale]

i don't know how to fix the issue but i don't usually use rigidbodies for 2d

i usually go with raycasts

[coral tusk]

How do you usually go about it?

I tried to avoid it at the start

[covert whale]

here's an old but nice tutorial series about it
https://www.youtube.com/watch?v=MbWK8bCAU2w&t=1s

[coral tusk]

@austere seal thanks for the help so far, I know it's a bit odd

[austere seal]

Yeah I'm just having a hard time understanding how you're doing it

[coral tusk]

Wanna just see the code?

or how would you go about this sticking mechanic? forgetting about all the weird stuff i've done

[austere seal]

I mean, I don't mess with forces a lot since the types of games I make don't need them

So it's not my area of expertise, I'm just trying to think of it from the perspective of someone who has taken college physics

[coral tusk]

Well you have helped with some ideas already so you efforts are great

Thank you for the help though

[austere seal]

Np, sorry I couldn't help more

[coral tusk]

All good really

haha

https://imgur.com/a/UieZrHn

I removed all gravity for this one and weakened the pull in force

It gains speed ans slowly seperates from the sides of the object

nuuuuu!

[ancient path]

@coral tusk what happens if you disable gravity on your ball
And enable it only when it’s not touching anything

[coral tusk]

The above is what happens when all gravity is off

Also I would still like the gravity effects for when I am stuck to the side of an object

[ancient path]

What type of movement do you want?

[coral tusk]

Frictionless, but attatched to the wall

would sort of look like a pendulum

[ancient path]

Like a bug?

[coral tusk]

Kinda

[ancient path]

Or a slime?

[coral tusk]

it's a slime

It seems the only way to get the movement I want so far is to find the difference between the last angle and the current angle

and "rotate" the velocity, so that it technically sticks to an object without sticking

I want to be able to eventually stay on and navigate around moving objects

Since pushing into the object, pushes the object :p

[ancient path]

Well

Are you gonna use animations?

Or add a soft body?

[coral tusk]

Nah, just gonna have it how it is, the blob rotates

I may add some animations to the object, but really the sprite itself is a separate object

The object is a non-rotating circle collider

As you can see by the outline of the square

[ancient path]

Ok so the problem is that it falls right?

[coral tusk]

Sort of

[ancient path]

Can you decrease gravity?
And increase friction?

[coral tusk]

But yeah the problem is I want it to stay stuck to an object, but still be affected by gravity

I will be using my own form of friction, the gravity I would like to avoid changing if possible

[ancient path]

You’ll need a way to counter gravity

So that would be friction

[coral tusk]

Yeah, but for now it will be frictionless

For countering gravity

I am thinking if there is a way to "movePosition"

but it's a bit janky the rigidbody version

[ancient path]

Well what happens if you use an opposing force against gravity

[coral tusk]

It doesn't slide down the side of blocks

if I remove gravity won't it no longer slide down a slope?

including upside-down slopes

an idea might be to apply gravity at 0 percent if I am perfectly on the bottom, and apply at 100 percent if on the sides and above...?

[ancient path]

That can work

[ancient path]

Or decrease gravity effects

[coral tusk]

The main issue is, I want to be able to stick here

but

With the gravity, it will force it to fall down still

but it needs to swing around almost like it's stuck to a conveyor belt

Or more like... A plunger on a slippery/wet surface, where it can slide around, but air suction causes it to stay stuck

[ancient path]

start trying some methods we said

[coral tusk]

How would I keep the object swinging around tho?

[snow willow]

forces

sounds like you want custom gravity sort of like mario galaxy

[coral tusk]

Not exactly

but sort of

I want there to always be a downwards gravity

[snow willow]

that's separate though

[coral tusk]

but I want to stay close to the walls

[snow willow]

sounds like you additionally want mario gravity

[coral tusk]

hmm maybe

Yeah sort of

when I do that though, it gains even more speed

https://imgur.com/a/UieZrHn

I know friction will solve it, which I will add eventually, but it shouldn't have to solve it, it should just pendulum without it

(above is me only holding the stick button)

with no gravity

[ancient path]

I think your method isn’t working

Of adding force to an object

[coral tusk]

Yeah me too

[ancient path]

Can you show again

[coral tusk]

I gotta figure out the rotating, I was trying to use the rotating of the sprite, but now I will try to actually use the raycasts that are detecting the ground

[ancient path]

The code for that

[coral tusk]

This applies it in the direction of the small pink line when holding the stick key

Currently it has 0, so it's turned off, my bad

Just been trying another method is all

[ancient path]

Can you do like

[coral tusk]

before it was on 2 for the gif above

[ancient path]

transform.LookAt(the wall)

And then

[coral tusk]

Not exactly, since it will look at the centre of the wall wouldn't it?

[ancient path]

Rigidbody.AddForce(transform.forawrd);

[ancient path]

Yes

[coral tusk]

yeah that would be a problem since it only wants to check the spot it's on

[ancient path]

Or use child object

Or

[coral tusk]

but also I can't rotate the object, maybe I can use a another child object for rotation looking

[ancient path]

Rigidbody.Addforce(wall.position - transform.position);

[coral tusk]

I can probably look at raycasthit.point

ohh didn't think it would work like that

that may still pull towards the centre tho

maybe

Rigidbody.Addforce(raycastHIT.point- transform.position);

might work...???

[ancient path]

What raycast are you doing?

I thing a circle cast

Can do well

But yes

[coral tusk]

Yeah I send out a raycast in the diriction of the circlecast hit since it gets the distance more accurately

also I debug the ray hit so I can see the pink lines

[ancient path]

Huh

You are already getting the distance in the Rigidbody

But as a vector

You only need the transform of the raycast hit

[coral tusk]

Well

I did this as a new implementation since the circle was being so innacurate

op, it didnt like that

        while (Physics2D.CircleCast(transform.position, (dist)* scale, Vector2.up, 0, layer_mask) && dist > 0)  //While circle collider hitting
        {
            playerBoarderHit = Physics2D.CircleCast(transform.position, (dist)* scale, Vector2.up, 0, layer_mask);    //Remember collision
            dist -= 0.01f;  //Constantly reduce checking distance until no more collisions
        }

[ancient path]

While

[coral tusk]

yeap

[ancient path]

What’s the while loop for?

[coral tusk]

so

when I raycasted to the hitpoint of the circle cast

it kept raycasting half way through the wall

so I made a while loop, that constantly shrinks the circle until it no longer collides with anything

and what that does, is instead of giving me the first hit, it gives me the closes hit (was having issues with this before)

which was the main reason I did it

I may not really need the raycast in there anymore, but it's useful for the debugging

[ancient path]

Well it doesn’t look like it works

[coral tusk]

Oh it's working

[ancient path]

Mainly because it’s respirating and probably not resetting

[coral tusk]

        float dist = collisionCheckDist;  //Reset distance

        // ================ ACTUALLY CHECKING FOR COLLISIONS
        while (Physics2D.CircleCast(transform.position, (dist)* scale, Vector2.up, 0, layer_mask) && dist > 0)  //While circle collider hitting
        {
            playerBoarderHit = Physics2D.CircleCast(transform.position, (dist)* scale, Vector2.up, 0, layer_mask);    //Remember collision
            dist -= 0.01f;  //Constantly reduce checking distance until no more collisions
        }

there we goes

Yeah it's resetting

[ancient path]

Rigidbody.Addforce((raycastHIT.point- transform.position).normalized);

[coral tusk]

rb.AddForce(new Vector3(playerBoarderHit.point.x, playerBoarderHit.point.y,0) - transform.position);

this what I got

i'll try it out

tis very weak

it seems to be doing the same as the previous code

but not as good

okay so it still gains speed

is there a way I can use movePosition without affecting the addforce/velocity?

and apply it to the rb instead of the transform itself?

//https://forum.unity.com/threads/get-the-difference-between-two-quaternions-and-add-it-to-another-quaternion.513187/
//https://forum.unity.com/threads/change-velocity-direction-and-not-magnatude.368272/



//[Put this in the if statemnt below when finished]
//Goal: get difference from last rotation to current | add difference to current movement direction
Quaternion difference = lastSpriteRotation * Quaternion.Inverse(playerSprite.transform.rotation); 
Quaternion velDir = Quaternion.Euler(rb.velocity.normalized);
Quaternion goalDirQ = difference * velDir;

Vector3 goalDir = goalDirQ.eulerAngles;

//Now to rotate this bad boy

Vector3 newVel = goalDir * rb.velocity.magnitude;
rb.velocity = newVel;

Would this be correct to apply a new angle to a velocity?

[subtle vessel]

No, taking the current velocity (a direction) and passing it into Quaternion.Euler (a rotation) does not make sense. That's like copy/pasting the position values from a transform into the rotation slots. Can you describe what you're trying to do a little more generally? Do you want the velocity to always align to the direction you're facing?

[coral tusk]

Like imagine an object is moving to the right.

I want to grab it, and rotate it 90 degrees, but fully using code without actually rotating any objects

Yes I think so

[subtle vessel]

Do you want the rotation to follow the velocity, or the velocity to follow the rotation?

[coral tusk]

There are website links in the code comments which I tried to use

Velocity to follow rotation

[subtle vessel]

Okay, and do you need forces from outside this script to be able to affect this object? Is this script the ONLY thing that's controlling the objects movement?

[coral tusk]

There will be a point where other code will move it

Currently it is just this one object

I made a wind pushing the object, actually, that's in this code too

But the only other way this code is being moved, is by the physics engine when hitting objects

[subtle vessel]

Okay, so I think you're best plan is to not deal with quaternions at all. You want to use transform.up (y-axis) or transform.forward (z-axis) to figure out which direction the object is facing

[coral tusk]

Unfortunately the object never ever rotates

The sprite does, I guess I could make it more accurate then use the sprite

But the object is just an invisible circle

Inside the blob

[subtle vessel]

Then use the sprites transform instead

[coral tusk]

Yeah fair enough

[subtle vessel]

And multiply that direction times the velocity's current magnitude

And set that to the velocity

[coral tusk]

I'm off the computer right now but how would I write that?

[subtle vessel]

I'm on mobile, so can't really write sample code

[coral tusk]

That's fair

Me too :D

I'm guessing to use the vec.forward as magnitude?

[subtle vessel]

rb.velocity.magnitude

[coral tusk]

Oh wait, magnitude is speed isn't it

[subtle vessel]

Yeah, you want to keep the same speed but use a different direction

[coral tusk]

Direction is velocity.normalised right?

[subtle vessel]

rb.velocity = sprite.transform.up * rb.velocity.magnitude;

[coral tusk]

Oh

Yeah okay that makes sense

I'll give that a try

Thanks a heap

Dam now I wanna jump on the PC but it's 3am

[subtle vessel]

Go sleep!

[coral tusk]

:'D

Yeah will do!

Thanks for the help!

[wide ginkgo]

Since no one answered, yes you are correct.

[burnt badge]

im running into a problem with 2d collisions. i have two objects, both empty objects with the same box collider, and both running the same script. the script contains a OnTriggerStay2D(Collider2D collision) with print(collision.gameObject.name);, yet only one of the objects script triggers, the other one does not

[covert whale]

maybe try ontriggerenter?

i don't think this it's unusual for unity physics that only one of them stays inside momentarily then the other is stopped

[burnt badge]

not working iether. the way im testing it is that i have a ball with a circle collider falling through the not working collider, then after a space, falling through the second collider

[covert whale]

are all colliders marked as triggers?

[burnt badge]

yes, both of them

[covert whale]

is one of them moving faster than the other

what collision mode are they on

[burnt badge]

the ball is the only thing moving, the triggers are stationary, and what do you mean collision mode?

like their material?

[covert whale]

can you show a video i don't think i get it

[burnt badge]

sure 1 sec

[covert whale]

on the rigidbody components they each have a collision mode

[burnt badge]

they do not have rigidbodies

[covert whale]

so how does ontrigger work then

[burnt badge]

the ball has a ridgidbody, but i didnt think objects needed ridgedbodies for triggers to work

[covert whale]

at least one of the colliding objects has to have a rigidbody in order for triggers to work

if the ball has a rb and it's the only one colliding with others it's fine

[burnt badge]

the balls ridgidbody is set to dynamic

[noble swan]

What about collision mode

[covert whale]

what is collision detection set to

[noble swan]

(discreet or continuous)

[burnt badge]

discrete

[covert whale]

try setting it to continuous and see if that helps

[burnt badge]

it did not

heres a video showcasing how i test it

the top collider is the one not working, you can see when it hits the 2nd collider the onEnter triggers

[covert whale]

try copy pasting the bottom one and putting it where the top one is now

and disable the one that doesn't work

[burnt badge]

nope, i just figured it out, it had to do with the layer of the object. Turnss out i made a mistake when editing the project settings collision matrix, thus causing the two objects to never collide

[covert whale]

oh ok

[burnt badge]

thanks for your quick replies though, its always nice to have a community you can count on

[bronze glacier]

can someone help me make an 2D endless runner game? idk what the hell im doing

i cant get any code to work

[compact knoll]

i'm sure if you shared the code you are working on, explained what is going wrong (including any errors you receive), and explain what you expect to happen with the code you share then someone will help you

[bronze glacier]

Tryna do the background of an endless runner

I've tried 5 yet videos

Nothing works

[coral tusk]

Ayo, this has no gravity, I want the object to continue moving around the circle based on the angle of the sprite

https://imgur.com/a/qqontzE

as you can see the sprite rotates, but the angle does not change

I assume it's something like this, but idk how to actually implement it for unity

rb.velocity = playerSprite.transform.forward * rb.velocity.magnitude;

although this seems to do nothing at all, idk if I will need to use the last rotation and compare it to the new rotation.

[coral tusk]

nvm, I realised the way I am coding it won't let that work

[glossy marten]

Why isn't my text showing?

[turbid heart]

what text?

normal color looks like alpha is 0. not sure though

[glossy marten]

Oh yeah I didn't see that but the problem still remains

Nvm I fixed it

Thanks @turbid heart

[finite garden]

Does anyone know how to detect particles on Raycasts?

My particle system has a World Particle Collider on it

[opal socket]

Detect gameobject owning particles I guess?

How precise do you need it to be lol

[finite garden]

the Collision mask of the particle systems is correct

and i've added the layer that the particles are on to the Raycast LayerMask

but it still doesn't pick them up

[glossy marten]

https://i.imgur.com/YkilH5w.png

How do I merge these box colliders to one?

[lean estuary]

Use composite collider or tilemap collider if those are tiles. To not snag between the segments use continuous collision detection.

[glossy marten]

https://i.imgur.com/Q94Aqxb.png

Should I put composite collider on the "GrassPlatforms"?

[lean estuary]

Composite goes on the parent object and uses all colliders from children.

[glossy marten]

@lean estuary When I add a composite collider 2d on the parent it will also add a rigidbody and every tile falls down

[lean estuary]

You should be able to set it to static.

[glossy marten]

THanks

[royal kindle]

So many GOs, wish i'll make something that big one day, lol

[glossy marten]

The boxcolliders aren't merging and I don't know why. The parent of every tile has a box collider 2d, rigidbody 2d, composite collider 2d and a tilemap collider 2d

In the tilemap collider 2d I checked "Used by composite"

[royal kindle]

your platforms aren't tiles

maybe cuz of that?

[glossy marten]

How do I make them to tiles?

[finite garden]

anybody have any information regarding this?

[opal socket]

Ygh you shouldnt do that

Smoke is just a gfx effect

What you care is whatever gameobject is spawn in the scene and spawns those particles

It should have one big collider you’re testing agains

Games are illusion buddy

[finite garden]

this is the one big collider, generated by the particle system

[olive mesa]

What's the most optimal way to render a grid in 2D?

I'm currently using 600 sprite masks to do this

[grand coral]

there's a grid default image you can set as a background image

if you need the grid to move around, i've made some scripts to do that so dm me and i'll help you with that

[olive mesa]

I've got the camera panning down, thanks though!

For the grid image, is it not usable as a sprite?

[grand coral]

i meant like making the grid repeat for infinite panning

[grand coral]

yeah it is

[olive mesa]

Ohhh, yes I do need that

[grand coral]

click the little circle in the sprite image selector and find the grid

[olive mesa]

I'm trying to make a level editor for my platformer

[grand coral]

ok if you need help with that lmk in dm

[grand coral]

it's not called grid i don't think

[olive mesa]

Oh, ok

[grand coral]

but it has a grid image

[olive mesa]

I'll look for it manually

[grand coral]

yeah there aren't that many

it should be easy to find

[olive mesa]

Didn't see it

I can just make one

[opal socket]

you're missing my point and not listening to me

https://forum.unity.com/threads/how-to-detect-collisions-with-particles-in-a-particlesystem.1103629/

you do you

[finite garden]

... How am I missing your point when I'm just showing you my collider?

I'll figure something out, thanks for your help 🙂

[opal socket]

I see a bunch of small colliders belonging to the particles, not one big circle collider

The website I linked should give you some info n what to do though

if you really want to detect collision between ray and individual particle

[strong plinth]

Ok so i am really new to Unity and I need to know 2 things for now: How to make a custom sprite and how to make movement code

ok thanks

[toxic solstice]

void Start()
    {
        playerRb = GetComponent<Rigidbody2D>();
        boxCollider2D = GetComponent<BoxCollider2D>();
        playerSpriteRenderer = GetComponentInChildren<SpriteRenderer>();//GetComponent<SpriteRenderer>();
        transform.position = spawnPoint;

        DoubleJumpMechanic();
        BoundChecker();
        
        playerSpriteRenderer.sprite = invincibleSprite;
    }

Hey guys, for some reason, playerSpriteRenderer's sprite isn't changing

invincibleSprite is a serialized field, so I dragged it into the inspector

And if you look at my hierarchy, the sprite renderer that is active is Player1 (the child)

So, I used GetComponentInChildren<>(), but nothing changed

Do you guys have any suggestion in dealing with this? I'm trying to change the player sprite via script

[elder minnow]

@toxic solstice Are you sure your invincibleSprite is set up correctly? If you accidentally dragged the "Player 1" sprite you wouldn't see a change.

[toxic solstice]

Yeah. This script is attached to Player (parent)

[elder minnow]

Do you get any error messages?

[toxic solstice]

No

[elder minnow]

Did you make sure you saved the script?

[toxic solstice]

Yes, it's saved

[elder minnow]

Try debbuging playerSpriteRenderer

[toxic solstice]

This is in runtime

Ignore the white rectangle flying there. It's the invincibleSprite I placed as a game object (completely separate)

[hollow crown]

Why is it disabled

[elder minnow]

That is not the SR intended, his GFX is on its child

[toxic solstice]

The sprite renderer I'm using is a component of Player's child named Player1

[elder minnow]

I don't know if GetComponentInChildren ignores the root

[hollow crown]

It doesn't

[elder minnow]

That is the source of the issue then

[toxic solstice]

So GetComponentInChildren was wrong?

[hollow crown]

Assigning things in the inspector is almost always the better way imo

[elder minnow]

More like if yout gfx is sitting in the child you have no reason to have it at the root

[toxic solstice]

Oh yeah. I completely forgot about this

Well, I won't dwell deep as to why it wasn't working via script

Problem solved! THanks guys!

[elder minnow]

It wasn't working because GetComponentInChildren doesn't ignore the root of the search, since "Player" had a sprite renderer, it was the one that was referenced

[toxic solstice]

What do you mean by that?

[elder minnow]

If you look closely at your own screenshot you will see* that it has the invincible sprite you wanted to change

Both your "Player" and its child "Player 1" had a sprite renderer, since you used GetComponentInChildren<> and the script was attached at the root that also had the component it was looking for, it didn't need to go down

[toxic solstice]

Huh, I thought GetComponentInChildren<> would skip the parent from the name itself

[elder minnow]

Does that make sense?

[toxic solstice]

By root, were you talking about the parent?

[elder minnow]

Me too, but I suspected it as soon as you showed that screenshot

That is why I mentioned it and Vertx replied #🖼️┃2d-tools message

Yeah

[toxic solstice]

That clears things up, then!

Thanks for explaining it :]

But if my variable was an array/list, would it continue it's search?

Since I only needed a certain spriterenderer, I didn't make an array/list of it

[elder minnow]

If you used GetComponentsInChildren<> (plural), you would need to cache it in an array since it would return all of them

[toxic solstice]

Do you know a method that works like GetComponentInChildren but ignores the root?

[elder minnow]

transform.GetChild(0).GetComponent<> does the trick, but you need to know the index of the child

If you have multiple and want to store all of them in an array you can just use GetComponentsInChildren<> and then check which one belongs to the gameObject of the parent

[toxic solstice]

Alright. Thanks a bunch, @elder minnow !

[bold apex]

Beginner in Unity, I'm making a topdown game and I'm thinking of using tilemaps for the background(floor and walls). What colliders do I use for the walls? Edge colliders? Box Colliders? Tilemap Colliders?

Also if there's any better way to do backgrounds I would like to know.

[chrome grove]

If youre using the Tilemap feature, Tilemap Collider would be the best.

[bold apex]

Okay, so then if I wanted to only give a part of the tilemap a collider, what would I do? make a separate tilemap for the walls?

my bad og

[next jetty]

Question (hope it's correct place to ask). Im using groundcheck, so i can't jump in air. I can only jump on ground layer. Im also using wall sliding, and walls also have ground layer so i can jump of them.
But when i created moving platform, new problem appeared. I need to make it ground layer so i can jump of it. But damn i can also wallslide on that moving platform now. Any way to make it impossible to wallslide from a single object like moving platform, even tho it's in the ground layer?

[calm wyvern]

you could check for the hits that you need for the wallslide that they are not the same object?

[crude dome]

This doesn't fall under only 2d but I'm learning how to make things move and they tell me things like Feilds, properties, and methods can anyone explain that to me in a bit more detail?

[ancient path]

feilds is not very important as it sounds, properties and methods are basically normal things you will use
a method example: cs void Start(){ }
as for properties and fields unity made a tutorial about it https://youtu.be/HzIqrlSbjjU?t=22

[crude dome]

void Start() is a feild?

[ancient path]

a method

[crude dome]

oh

is a method like an event?

[ancient path]

similar, it's a place where theres more code

and you call it

yes event

and theres even different purposes for methods

[crude dome]

I see, are feilds kind've like variables?

[ancient path]

i guess you can call it that
but they are all methods in the unity tutorial
but using a different words than normal

[crude dome]

are they needed?

[ancient path]

i havent used them myself

[crude dome]

what do you use instead? I'm trying to move my sprite

tutorial/guides that I've seen use Rigidbody2d and then create a feild i think

[ancient path]

unless you'll need very specific and repetitive values then yes you could use them

[ancient path]

i move them with input and setting velocity

[crude dome]

Okay

Ty

[compact knoll]

Fields are class level variables. No idea what that other guy was getting at, but check this out for info on fields and properties
https://stackoverflow.com/questions/295104/what-is-the-difference-between-a-field-and-a-property/295109#295109

[crude dome]

Okay

Feilds just store data kinda right or nah?

They are literally just variables

[crude dome]

okay

Can someone tell me what is wrong with this script? It is supposed to be a patrolling behavior that flips once the gameobject gets near a wall or an edge, but all it does is make the gameobject flip around without stop every frame.

For the ground i'm using a tilemap, could that be related to the problem?

Your Flip() method always sets facingLeft = true;

well it actually always sets it to false and then true, but since it does true second, that's what sticks.

also - you are going to flip every FixedUpdate where you're not touching the ground or you are touching a wall

which is probably... going to be constantly as long as you're near a wall?

[cloud crypt]

The gameobject is not touching a wall no

[snow willow]

checkingGround = !Physics2D.OverlapCircle(groundCheckPoint.position, circleRadius, groundLayer);```

this looks to say "checkingGround is true whenever you are not touching anything at the groundCheck"

and then this will run whenever that is not true

        if (!checkingGround || checkingWall)
        {
            Flip();
        }```

so if you are touching the ground (two negatives!) then it will flip every frame

that's just what I'm gathering from your code here.

I'll see if I can tweak it then. That is a tutorial code, i'm checking to see if I just use it straight up it would work because I had tried implementing into my own and it wasn't working

Guess the problem was in the original code itself then

[snow willow]

maybe? Idk the code is a bit hard to understand given the uninformative variable names

[cloud crypt]

I mean I have the video tutorial but it's 15 minutes lol

[snow willow]

Since the two overlapCircle checks are roughly the same it seems like this will almost always be true if (!checkingGround || checkingWall)

and again - there's no way Flip should always be setting facingLeft = true like that

more likely it should just say facingLeft = !facingLeft;

[cloud crypt]

Yes I did that in my own code, didn't change.

Both versions didn't work. The problem must be in the calling the Flip() method constantly
