[still tendon]

i've put coliders on my character

but i cant find how to set the floor

so he just falls through the earth

[distant pecan]

add a tilemap collider

[still tendon]

is that a component?

[distant pecan]

yes

[still tendon]

alright thanks

i will try

it worked

thank you so much!! ive been stuck on that for a while @distant pecan thank youuu

[distant pecan]

also if you start getting stuck on the ground, all you need to do is add a composite collider to merge tiles colliders

[still tendon]

how do i change the size of the tile colliders

since they are a bit to small

[silk compass]

how can I SetCursor when I hover over specific region of the sprite? I thought of creating another invisible sprite and placing on top of it, but perhaps there is more efficient way?

[still tendon]

How can i change the size of unity 2d tilemap colider since they are a bit to small so my character hits the bump between them? Ping me with the answer please

[violet flame]

any recommendation on existing pattern / package for using vector art in UI?

[trim jay]

This jump script is confusing me

it says that it coliding with its self

and even tho i made it were it can only jump on a layer mask "Platforms" it will just keep leting me jump "Fly".

[trim jay]

Anyone?

[still tendon]

whats the best way to get tile collision in tilemap?

like collided with tile of player

[rose radish]

@trim jay check your mask, make sure your player isn't in a layer included there

[trim jay]

The player's layer is default

[ruby knoll]

Can someone help me out to find out why my code doesnt seem to work for my player movement

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

public class Player_Movement : MonoBehaviour
{

public float movementSpeed;
public Rigidbody2D rb;

float mx;

public float jumpForce=20f;
public Transform feet;
public LayerMask groundLayers; 




private void Update()
{
    mx=Input.GetAxisRaw("Horizontal");
    if (Input.GetButtonDown("Jump") && IsGrounded()) 
    {
        Jump();
    }
}

private void FixedUpdate()
{
    Vector2 movement = new Vector2(mx * movementSpeed, rb.velocity.y);
    rb.velocity=movement;
}

void Jump()
{
    Vector2 movement = new Vector2 (rb.velocity.x, jumpForce);

    rb.velocity=movement;
}

public bool IsGrounded()
{
    Collider2D groundCheck=Physics2D.OverlapCircle(feet.position, 0.5f, groundLayers);

    if (groundCheck!=null)
    {
        return true;
    }
    return false;
}
}

[vocal condor]

Don't cross post and why is jump being implemented in Update rather than Fixed Update?

[ruby knoll]

thank you so much I didnt catch where the jump was being implemented

[still tendon]

Why my Camera don't see my rectangle ?

[robust ivy]

your rectangle need to be an Image and not Sprite Renderer if you want to be UI

[still tendon]

Ty

[hollow crown]

Lerp returns a value between A and B based on the 0->1 t value you pass in

you're passing an extremely small value in

so you will get back pretty much A

[craggy kite]

Where do you call the function?

[hollow crown]

No, you need to use Lerp properly

where you pass in a value that moves from 0->1

[craggy kite]

Lerp1 need to be run every frame, not on click

[hollow crown]

Color origin = new Color(1, 0, 0);
Color destination = new Color(1, 0, 0);
float elapsedTime = 0;
while(elapsedTime < duration) {
    currentColor = Color.Lerp(origin, destination, elapsedTime / duration);
    elapsedTime += Time.deltaTime;
    yield return null;
}
currentColor = destination;```

example in a Coroutine

[craggy kite]

There we go

[hollow crown]

The "pass Time.deltaTime * speed" model of using Lerp would need to be called continuously and A should be the current colour, not the origin colour

but it doesn't guarantee a timeframe, it just moves the current closer to the destination every call

different origin and destination? I'm not sure what you mean

[craggy kite]

Just flip start and target color

[trim jay]

I am fairly new and it is say that the end } is "Unexpected" can i get some help.

[robust ivy]

show the beginning

you must have an extra open brace somewhere

oh i see it

[robust ivy]

if (collision.collider.tag == "Ground") {

then another { right after

[trim jay]

i see

Thanks!

Heyo, I'm trying to optimize my level thumbnail generation, currently I load the level and render it to a rendertexture (optionally saving it to a jpeg), then discard the level that I just loaded. However this is quite slow (a level consists of tens or hundreds of tiles) so instantiating all those is slow. What I'd like to try is to manually render the level to a texture myself without having to instantiate all these objects. I'm thinking of using Graphics.Blit or Graphics.CopyTexture, however these do not provide any rotation so I'd have to think of something for the rotation of tiles. Anyone here have any pointers on how to achieve this?

[slow egret]

https://cdn.discordapp.com/attachments/702820108732465192/790628060717908008/unknown.png why :(

[hollow crown]

Quaternion.Slerp interpolates between two Quaternions, clearly

[slow egret]

i didnt understood

[hollow crown]

https://docs.unity3d.com/ScriptReference/Quaternion.Slerp.html
public static Quaternion Slerp(Quaternion a, Quaternion b, float t);

you are passing Vector3s to it

You could use https://docs.unity3d.com/ScriptReference/Quaternion.Euler.html to convert them, or use Vector3.Lerp

depending on the application

[slow egret]

oh

[slow egret]

i didnt know vector3.lerp existed

ill try it

@hollow crown there is no quaternions at rot

[hollow crown]

you're using Quaternions very incorrectly

This doesn't logically make any sense

[slow egret]

idk anything about quaternions

XD

[hollow crown]

Quaternions are a complex number representation of a rotation

you can't just take 3 of their values and construct a Vector3

if you want to use Vector3s you probably want .eulerAngles

[slow egret]

like Vector3.eulerAngles or transform.rotation.x.eulerAngles?

[hollow crown]

transform.eulerAngles

[slow egret]

im not atually trying to do that know

im gonna add it later

for now i wanna make the camera smoothly slide into player

[boreal saddle]

Oh didnt realize there was 2d code

https://hastebin.com/wokuyozoyo.cpp

Having an issue were the bullt only goes in one direction rather then the direction the player is facing

Any help would be much appreciated !!

[still tendon]

if i were to make a script where i would want my player to go a certain direction until it hits something, how would i make it

[boreal saddle]

why not make movement scripts then add box colliders to the player and the object you want it to stop at?

[still tendon]

what

I want it to go a certain direction even though you are pressing diffrent buttons

[boreal saddle]

oh i see

so kinda like apply force from one direction until it hits a trigger ( like a spot on the map or a tree ) then it stops?

[still tendon]

yes

if you press a button from wasd

[boreal saddle]

thats a good question lol

[still tendon]

lmow

[tropic inlet]

@slow egret

Vector3 rot = transform.rotation.eulerAngles;
rot.y = p.transform.rotation.eulerAngles.y;

Vector3 pos = p.transform.position;
pos.z = transform.position.z;

transform.rotation.eulerAngles = rot;
transform.position = pos;

does this work?

[craggy kite]

@tropic inlet This should work even if it does nothing yet, right. Just copying the same thing twice in rot.y and pos.z

So I would like to create a game like My Friend Pedro (I just begun with unity). I know this is a big project and I want to take it in small steps, like learning how to make the animations, graphics, shooting physics, body physics, blood physics, how to make good lighting, sprites, all that. Can anyone give me any adivce on what to start with and for any tutorials?

[thorn swallow]

Brackeys on Youtube has a ton of great content, including some great 2D sprite and lighting tutorials. Code Monkey has a lot of really good C# tutorials for Unity

Follow along with tutorials while you prototype things, then refactor what works later for the final game

[north oriole]

HI I have a question, I just watched a video from Unity and wanted to know where i get the level Generator Script? (https://www.youtube.com/watch?v=mFIAGVydVu4)

[thorn swallow]

The description of that video has a download link for a preview build which probably includes the generator script

[north oriole]

I downloaded it but I don't have any Scipts can you download it for me and send it to me please?

[north oriole]

It is very important to me @thorn swallow

[thorn swallow]

Sorry, I'm unable to download it right now, but if it's not part of the download then I don't know

[north oriole]

[wraith root]

I'm trying to make a 2d camera system similar to that of Smash's - basically a camera follows all players, but it is confined to a certain area. I'm using cinemachine, and I have virtual camera that follows a targetgroup made of all players. Similarly, I have a cinemachine confiner that confines the screen edges to the correct bounds. This looks good for the most part, but I want for the cinemachine confider to override all else - there's certain player orientations where the camera is forced to go outside of the confider, but I want to force the camera to always stay inside of the confider no matter what. Any ideas on what I can change to acheive this?

[azure gulch]

If anyone is having an issue with building a mobile game, and then it slowing down/freezing after a few minutes, well, I have found the solution after days of researching. Message me if you are having the same problem and I can give you a few pointers on how to optimize your mobile game in ways that aren't really fully explained in documentation or forums.

@wraith root I personally haven't messed around with cinemachine very much. You could use a Vector3.Distance check between the camera and some points on the confider.

[wraith root]

right, but you still can't limit the position of the camera - I'm thinking there's got to be a built in way somehow

[sand elk]

just use a script with Mathf.Clamp

[wraith root]

I've tried that before but cinemachine just overrided my clamp - I'll try again

[sand elk]

parhaps LateUpdate @wraith root

[wraith root]

yeah I've tried that but Ill try again

Awesome thanks! I've have tried the confiner but maybe playing around with that script might work

[trim jay]

i am trying to make a melee combat system and for some reason it is not detecting that it is hiting the enemy and the debug.log it not triggering

And i do also have a attack point

[clear tusk]

You are not using any of the 2d collision callbacks functions
OnTriggerEnter2d.or OnCollisionEnter2D

@trim jay 👆

[trim jay]

That would be in line 34 right?

[clear tusk]

Nop

[trim jay]

?

[clear tusk]

You are using an Overlappingcircle

[still tendon]

What is that?

[clear tusk]

Not for you for the other dud

[still tendon]

Oh ok ._.

[trim jay]

so what do i use instead of a overlappingcircle

couse the over lappping circle is for the collision

[clear tusk]

But you don't use for attacks it will work but it will need to be a little bit changed.
Just use one of the function that I have listed above

[trim jay]

Put it on what line?

and if you could not telll im very new to coding

[clear tusk]

Those are functions they are the same as Update and start they are called by the engine when 2 colliders collide

[trim jay]

So put void OnCollisionEnter2D()

[clear tusk]

Yes

[signal berry]

Hey!
Was wondering if messing with basic rigidbody2d velocity was better done in fixed update?
or if its fine to do it in the normal update

[trim jay]

sorry had to do somthing but what do i put under the void OnCollisionEnter2D()?

[clear tusk]

@signal berry always the physics operations are done on the fixedUpdate

@trim jay you can just check the documentation and you will learn about it and more things

[signal berry]

thanks @clear tusk

[sharp crescent]

hey, trying to write some code involving two separate colliders within a single object, without using a companion child object to act as a foe collider naming system. I used physics 2d materials to attempt to differentiate the colliders but it seems to just read them both regardless. any suggestions?

[coral nest]

create 3 public circlecolliders

[sharp crescent]

thanks for the quick response! had been lookin a bit and actually just found this post too

[trim jay]

For some reason when i make a drag and shoot movement thing it wants to go to one direction.

[coral nest]

what is your min and max power?

they should be between 1 and -1

since you're essentially trying to normalize the direction of your shot

That could be an issue...

[coral nest]

You can try changing line 46 to force = new Vector2(startPoint.x - endPoint.x, startPoint.y - endPoint.y);

[trim jay]

the min is -8 and the max is 8

[coral nest]

I'm missing the bug somewhere

[trim jay]

It works Thank you. This discord server is very helpful.

[dusk sail]

Heloo guys im new to Unity can you help me fix this?

note: PewPew script is in a prefab.

[vocal condor]

What's working and what isn't? We don't know what you need help with. What the "this" is inferring to.

[dusk sail]

what worked is that in codes it detected the Scripts "Stats".
what didnt worked is that when selecting the "Stats" in components, I cant find it.

is this possibly a bug?

[vocal condor]

Well, unless you have a prefab stat object (one that has a component of type specific to prefab) the list will be empty. What did you think was supposed to be visible?

That's in the assets folder.

[dusk sail]

ohhhh...

Thanks for telling me, i will try to adjust my work.

[vocal condor]

If the Stat was a struct, you would have a default value to manipulate. Else assign it a new Stat as default or it'll be null.

Where it'll expect a reference (a component implying that an object exists in the scene with said component or possibly as a prefab) if null.

[dusk sail]

I'm sorry im a newbie to Unity, there are some term you used and I didnt know what it is.
is it okay if I asked a question maybe later?

[vocal condor]

Default meaning on declaration give it an initialization.

Should always be fine to ask questions here.

[dusk sail]

Thanks.

Let me explain..
PewPew is the bullet (prefab) who has the damage.

do you think it will fix the problem if I put the damage (code) to the gun instead?

[vocal condor]

Try public Stats stats = new Stats(); (assuming stats isn't a Monobehaviour).

[dusk sail]

Stats is a monobehaviour.

(Stats : Monobehaviour)

[vocal condor]

Then you'll need a reference to the object with component stat (in the scene or assets folder as a prefab)

If in the scene, drag and drop said object into that slot. Same applies if a prefab (know that one references an instance the other references a prefab)

Something of the sort.

[dusk sail]

oh god you are right

it finally detected the Stat script

Thanks @vocal condor

[dusk sail]

Something messed up... when I play the game, Unity disables movement.

Someone have any idea how to fix this?

[shadow iris]

please help

i really need help

[obtuse torrent]

If I want to add the players x velocity to a projectile when it's shot how can I do that?

[smoky loom]

i need help for when you presse a UI Button its put all UI Invisinsible

im a beginner code

[meager mural]

put all other UI in an array, and disable them if you click on a specific button

[lean estuary]

Look into CanvasGroup, it's the most efficient way

[smoky loom]

i mean in a script when you clique a button UI it disappear all the UI ! (the button disappear to!)

[smoky loom]

im making a menu for my game.

i need the script for that

[distant pecan]

Put all the UI inside a empty rect transform, then do rectTransform.gameObject.SetActive(false);

Easiest way

Or you can go a step further and use canvas group

[smoky loom]

ok what a rect transform

[distant pecan]

Its a transform type that is used on canvas

[smoky loom]

ohh ok

[distant pecan]

Right click the canvas, create empty

[smoky loom]

ok then?

[distant pecan]

Drag everything into there, then just enable/disable that gameobject

[smoky loom]

ok thx

what about the script for that?

[distant pecan]

using UnityEngine;

public class MyClass : MonoBehaviour
{
    public GameObject canvasPanel;

    public void CanvasThing(bool state)
    {
        canvasPanel.SetActive(state);
    }
}

[smoky loom]

oh thx!

shold i put the script to the button?

[distant pecan]

Put the script on any GameObject in the hierarchy, then use the function to set it false or true

[smoky loom]

ok thx

[smoky loom]

wow

it works!

after million try!

thx

[obtuse torrent]

I'm attempting to use this code : https://pastebin.com/S8Awp6Za to make an enemy shoot a projectile in attempt to stop the players projectile, yet it doesn't react. Does anybody know any way to fix this?

[exotic owl]

take a different approach on the issue

[exotic owl]

create a larger circle collider and use that as a.. onColliderEnter -> try to stop the bullet.

[obtuse torrent]

I just realised the entry condition (not shown in the script) only detected the player, not the bullet

[drifting elk]

            GameObject tempProjectile = Instantiate(projectile, weapon.position, Quaternion.identity);
            
            // Get mouse position and get the shoot direction
            Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            Vector3 dir = mousePos - weapon.transform.position;
            
            // Add velocity towards the mouse position
            tempProjectile.GetComponent<Rigidbody2D>().velocity = dir * speed;```

I am trying to shoot a bullet towards my mouse position. It works, but the speed of the bullet is slower/faster in certain directions? It is not every direction the same speed?

Oh it depends on how far away you are clicking from the object

Any idea on how to solve this issue?

[tropic inlet]

normalize

[drifting elk]

the dir?

[tropic inlet]

Vector3 dir = (mousepos - weapon.transform.position).normalized;

yes

always normalize vectors that are supposed to serve as a direction

[drifting elk]

Still having the issue, I tried that 😦

[tropic inlet]

are u sure

[drifting elk]

Yes

I can make a short video

[tropic inlet]

ok

[drifting elk]

    {
        // If the left mouse button is pressed
        if (Input.GetMouseButtonDown(0))
        {
            // Spawn projectile
            GameObject tempProjectile = Instantiate(projectile, weapon.position, Quaternion.identity);
            
            // Get mouse position and get the shoot direction
            Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            Vector3 dir = (mousePos - weapon.transform.position).normalized;
            
            // Add velocity towards the mouse position
            tempProjectile.GetComponent<Rigidbody2D>().velocity = dir * speed;
        }
    }```

This code

[tropic inlet]

strange
that looks like exactly what would happen if it wasn't normalized

could there be some additional script either on the bullet or on the object spawning it that you forgot about that could be adding extra undesired force?

[drifting elk]

No, this is the only code it has

[obtuse torrent]

Is there a 2d version of transform.lookAt()?

[tropic inlet]

u can make ur own

actually tbh

transform.right = target.transform.position - transform.position;

lol

[lean estuary]

It has a worldUp parameter

[tropic inlet]

@drifting elk how about

Vector3 dir = mousePos - weapon.transform.position;
dir.z = 0;
dir = dir.normalized;
tempProjectile.GetComponent<Rigidbody2D>().velocity = dir * speed;

[drifting elk]

Lets try

Yes! That works!

[tropic inlet]

Oh, damn

[drifting elk]

What exactly was the problem and what does normalize do?

[tropic inlet]

it would seem the mousePos and the object have different Z positions, then?

because setting the z of the direction to 0 is the main thing that solved the problem, right?

[drifting elk]

yes but only setting the z to 0 didnt work

because i tried that

[tropic inlet]

oh

[drifting elk]

its a combination of the z and normalize

[tropic inlet]

so, when u do

b - a

where b and a are position vectors

you get a line going all the way from a to b

this means if b is far from a, the line will be long

if close, the line will be short

if u multiply the line by the number two, the line gets twice as long

this is undesirable for direction vectors

[drifting elk]

ah yeah

[tropic inlet]

so u normalize, to make it a length of 1

so that u have more control over the final speed/direction

[drifting elk]

Thanks 😄 !

[still tendon]

Im so confused 🥴

nevermind, i figured out.

[uneven rune]

Anyone know why this returns 0, 0? I have 2 logs, it has one with the correct location, but then it gets 0, 0!

[clear tusk]

@still tendon you will need to use and operator orthe pr operator

Between each condition

[still tendon]

yep i figured out

i have another problem...
I am trying to attach a gameobject to a prefab's public variable, but i just can't drag it into the field, nothing is happening

[clear tusk]

What is the type of the object uou are trying to attach, also make sure that you are saving the prefab when you drag and drop the game object

[plush coyote]

Raycast doesn't return a Vector2

it returns a RaycastHit2D. So the first time, it is actually assigned a Vector2, but the second time you are giving it something else (a RaycastHit2D). I have no clue how it isn't erroring (unless it is)

[still tendon]

I want to attach the Transform component of a game object

here

[plush coyote]

Dragging in the whole gameobject to that slot doesn't work?

assuming both of these objects are in the scene?

no, i want to drag this while the prefab is not on the scene

is that possible ?

[uneven rune]

lol

[plush coyote]

no

[still tendon]

ow

okay

[plush coyote]

You need to instantiate the player, then get a reference to the transform after it has been instantiated

[clear tusk]

You can just use FindGameObjectWithTag or similar ways

[uneven rune]

ping
It is a point

[still tendon]

i mean, the player is on the scene but not the prefab

but some other components are working just fine, that's why im confused

[plush coyote]

Whoops, then I guess it is returning 0,0 by default, since I doubt it hit anything

and structs cant be null

[uneven rune]

It returns 0 for not hitting anything!!?!??!?!?!?!??!?!

Why can't it just give me the point where it didn't hit anything?

[plush coyote]

Cache the raycasthit, then do if (hit)

[plush coyote]

because its checking the whole line, so there are many points that it didn't hit anything

do you want the end point or something?

[plush coyote]

Scene objects shouldn't interact with asset folder objects unless you are just instantiating them

[still tendon]

ok

[uneven rune]

Got tired making so many if else statements for the ray I just made a function LOL

And now its still not working. Good job, me.

Think I fixed it

[meager mural]

Function is grey, You're probably not usingi t

[uneven rune]

its fixed

and I am using it

idk why its grey

not grey anymore

I just added an exponent to my camera and it is having the opposite effect

its slowing it down

cause it is too slow originaly

I'm trying to use a button in a menu scene and I'm using this code to go to the first level, but for some reason it simply just does nothing.
This is the code ```cs
public Button Button1;
// Start is called before the first frame update
void Start()
{
Button btn = Button1.GetComponent<Button>();
btn.onClick.AddListener(clickTask);
}

void clickTask()
{
    SceneManager.LoadScene("Level 1");
}``` and in the button it's using the correct function.

[meager mural]

I would just make clickTask public, and drag it onto the OnClick event on the button component in the inspector

im dumb

I didnt

put a pos in Vector3

u can use Input.GetAxis, y'know

    float x = Input.GetAxis("Horizontal");
    float y = Input.GetAxis("Vertical");
    pos += new Vector3(x,y,0).normalized * speed * Time.deltaTime;

}

A,S,W,D are automatically mapped to it

which can be changed in ur project's input settings, if u ever change ur mind about which keys to use

@boreal saddle Bro there is 1 tutorials Of 2d Weapons

[boreal saddle]

in the discord?

[boreal saddle]

actually got another question lol. I have a code set up to flip the player depending on the x input (isFacingRight). I just added a feature where you can aim where the moue button is but now when you flip the aim in inverted

how can i cancle out that inverting ?

ooo couldnt i copy my is facing right code onto the aiming thing

[brittle lagoon]

does an yone know how to make it so my character respawns

every time he dies

?

[atomic patrol]

Can someone explain how to make a Terraria style Tilemap with tiny cells and procedural world gen ?

[green egret]

@brittle lagoon so bassically, when your character dies/get hit maybe do something like
if(hp = 0) {Invoke("respawn", 2f);} //wait 2 seconds} void respawn() {Instantiate(yourCharacter);}

Hi, I'm using Tilemap Collider 2D for my map, but the player tapping a frame gets stuck.
The game is platformer and I am using the transform.position.

Does anyone know how to fix it?

[atomic patrol]

can someone explain to me how to draw sprites on a grid through comand and make a 2D procedural terrain out of it ?

[atomic patrol]

help :3

[clear tusk]

@warm cedar use a 2d physics material on the colliders that the player gets stuck on

@atomic patrol check this article
https://medium.com/pumpkinbox-blog/procedural-map-generation-with-godot-part-1-1b4e78191e90

[warm cedar]

I've been trying that, but it doesn't work.

[atomic patrol]

ye but not 2d topdown like 2d

terraria is an example

i just want to draw tiles on my grid and create a procedural generation out of it

[clear tusk]

@warm cedar what's the settings you set for the material

[warm cedar]

I have tried 4 combinations.

With friction, without friction, with bounciness and without bounciness

[clear tusk]

@atomic patrol in that case you can draw the tiles on the grid and make bunch of them with different appearance and shape turn them into prefabs and instantiate them randomly.
If your idea is to do a procedural generateda dungeon you can take a look at this tutorial
https://youtu.be/qAf9axsyijY

[warm cedar]

I have uploaded a small video of the problem in case I miss something;
https://drive.google.com/file/d/1OR_Ft1DnY13--xN8F5PAyPJFXhb-0E45/view?usp=sharing

[clear tusk]

I will take a look at it

[clear tusk]

The issue is the colliders. You have 2 ways
One is 2d materials
Second is to use a raycast from the player position to forward direction and get the normal of the collider the ray cast hit and if it is 90 degrees then add for in the opposite direction

[elfin sandal]

what resolution am i supposed to have my game at with the 2D pixel perfect camera component?
there's a reference resolution field in the component
does that mean the game resolution is supposed to be that resolution?

[atomic patrol]

it's a side scroller 2d procedural terrain not dungeon :p

[clear tusk]

Reference Resolution is the original resolution your Assets are designed for.
So in other word it depends on the canvas size you used when you created your assets (sprites)

[clear tusk]

I have no idea then, sorry

[atomic patrol]

can someone explain to me how to draw sprites on a grid through command and make a 2D procedural side scroller terrain out of it ?

[elfin sandal]

well when I made a build of the game the size of the reference resolution it was really blurry when I maximized it

[sterile timber]

Hey guys, I'm having trouble using a Sprite Renderer(with a billboard) with a 3D Mesh. When my sprite gets close to the mesh it goes through the mesh. How could I avoid it?

[robust ivy]

isnt that ragnarok online

[sterile timber]

"yes". i'm rebuilding the client

[robust ivy]

is the angle of the billboard going throught the mesh? you can check in scene view in 3d mode

not sure ro had any 3d thought

dont know how you can flatten all this on the same z position to make it sort correctly since its 3d objects

[sterile timber]

the angle of the billboard going through the mesh, yes

well, I guess it had since these models are read from ro data file

[robust ivy]

one thing is sure is you have to sort character over all other layer using the feet pivot of the character, if the map is all 3d then instead of y like a 2d game you would use the z

[sterile timber]

The z part is already done, the sorting kinda. I've added a sorting group to both the character and the model, however couldn't get it to work, I've tried making the character a positive value and the mesh either 0 or negative

[cobalt valley]

hello how can i make to my player dont jump on the walls?

[west sundial]

One idea is to use one or two raycasts that is pointed downwards instead of coll.isTouchingLayers(ground)

public static RaycastHit2D Raycast(Vector2 origin, Vector2 direction, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, float minDepth = -Mathf.Infinity, float maxDepth = Mathf.Infinity);

@cobalt valley RaycastHit2D hit = Physics2D.Raycast(origin, directon, rayLength, layermask: ground)

[cobalt valley]

i make this to the player can get stuck on the walls but now he can get inside of the walls

[elfin sandal]

anyone know how to reduce blur with the 2D pixel perfect?

I built the game with the reference resolution but it's still blurry

in the editor it looks crisp

[west sundial]

have you put the sprite filter modes to Point (no filter) ?

[elfin sandal]

yes

is there a build setting that affects it?

because everyting looks good in editor

[west sundial]

[hybrid plinth]

Ok so basically by default the enemy walks back and fourth and I set that up by making the enemy flip when he reaches the end. However when the enemy levitates in the air (setup by a range value) Im trying to figure out how to make him flip again to always face the side the player is on

I understand the flipping part of it

just not how to make that happen by the players location

[abstract olive]

Just compare the x-values of the player and enemy's position. If the player is to the left of the enemy, it'll be smaller.

[hybrid plinth]

Do you know how I can make it so my enemys projectiles dont effect him

Here is my script for the enemys bullets. Im trying to make it so his bullets dont have collision on the enemy (himself)

[still tendon]

so, i wanna add spread to my shotgun, for that i want to take the firepoint.rotation and add Random.Range(-10f, 10f) but it is telling "CS0019 C# Operator '+' cannot be applied to operands of type Quaternion and 'float'' " i understand the problem, but don't know how to fix it. Help plz '^'

[tropic inlet]

u need eulerAngles

and

u need pick the specific axes to modify

Vector3 rot = firepoint.eulerAngles;
//modify either rot.x, or rot.y, or rot.z
//e.g.,
//rot.x += Random.Range(-10f,10f);
firepoint.eulerAngles = rot;

x rotation = looking up and down
y rotation = looking side to side
z rotation = tilting your head to the side

or u could multiply the quaternion to rotate it

https://forum.unity.com/threads/rotate-a-quaternion-20-degrees-around-y-axis.90990/

up to u

[granite jasper]

bit of a beginner question but what do when images don't actually correspond to their bounds being set and refuse to be dynamically resize instead stretching in wide steps only.

The UISprite doesn't have this issue but any custom texture I use does so it must be me being stupid

[still tendon]

@tropic inlet i used

GameObject bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation * Quaternion.Euler(new Vector3(0, Random.Range(-10, 10), 0)));

But for some reasons, my bullet is still moving straight as usual. I also tried ur code but it's doing the same thing.

I just checked if i had any other code changing the bullet's rotation, but nothing

[tropic inlet]

This is for a 2D game, right?

Since we're in #🖼️┃2d-tools

[still tendon]

yep

[tropic inlet]

maybe you need to change the Z rotation, then?

GameObject bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation * Quaternion.Euler(new Vector3(0, 0, Random.Range(-10, 10))));

[still tendon]

ok i'll try that

nope, nothing is changing

rb.AddForce(firePoint.up * 100, ForceMode2D.Impulse);

i don't thing this piece of code is changing the rotation, but... meh. maybe ?

[tropic inlet]

hmm

only one way to find out whether the quaternion multiplication is doing anything

GameObject bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation * Quaternion.Euler(new Vector3(0, 0, Random.Range(-10, 10))));

print(bullet.transform.rotation.eulerAngles);

[plucky sorrel]

how do i check when a float hits 0?

[tropic inlet]

i don't thing this piece of code is changing the rotation, but... meh. maybe ?
I don't think AddForce changes rotation

[tropic inlet]

When it hits exactly 0?

[plucky sorrel]

yeah

[tropic inlet]

That might be tough, 'cuz doubles/floats can be imprecise, but

[plucky sorrel]

it subtracts 1 everytime you do something

[tropic inlet]

https://stackoverflow.com/questions/3874627/floating-point-comparison-functions-for-c-sharp

Personally

I prefer using <= or >=

with floats

due to imprecision

0.00000001 and -0.00000001 are not 0

[still tendon]

Do the rotation is changing but the bullet is not following the rotation.
So ill try to make the bullet move by itself based on its rotation. That's my last idea 🤔

[tropic inlet]

oh

i think i know why

the problem is

it's adding firePoint.up * 100 force

but

firePoint.up is not the same as transform.up for the bullet

make sure the bullet uses .AddForce(transform.up * 100, ForceMode2D.Impulse)

[still tendon]

so i should add force to transform.up in the bullet script ?

[tropic inlet]

ye

[still tendon]

okay thank u !!

that works. thaaaanks !

For your answer on the top down movement check this https://youtu.be/whzomFgjT50

@runic kite you can use the edge collider or calculate the hit direction bu using collider.contact point and see if the vector from the hit point to the center of the cube is equal the up vector normalized

Hey, i'm setting at runtime a BoxCollider2D size by taking the difference between the Y pos of two bones on the model... but the size i'm getting out of this creates a collider that is almost twice al tall as the distance between the two points... am i making a dumb mistake somewhere? (PS it's a 3d model in a 2d environment)

  BoxCollider.size = new Vector2(
            BoxDefaultSize.x,
            Mathf.Abs(head.position.y - Mathf.Min(leftFoot.position.y, rightFoot.position.y))
        );

[waxen surge]

it uses an already existing player for it but all i have is a sprite that i cant add scripts to

[still tendon]

how do I add collision to this capsule in between the image

it isnt a platformer, you use the arrow keys to move

[mortal shard]

@still tendon if you just want the bottom / "feet" to collide, remove any default collider, then add a circle collider, and modify the collider position in the inspector to be down where the "feet" would be

[still tendon]

oh yeah that's what I had in mind

ok

I'll try

How can I use a render texture to draw directly on a canvas Raw Image? Almost every tutorial I've found (been looking for hours) explains how to implement this for drawing on 3D objects but not drawing on UI.

Hi everyone, I have a problem and I dont know how to fix this

When i want finish lvl in my game a must go to the end maps and stay in one place

I want add extra point if you will be there before clock show 0 seconds

But I have this error

Fist I want that see this extra points in console

this is error:
NullReferenceException: Object reference not set to an instance of an object
ExitThisLevel.OnTriggerEnter2D (UnityEngine.Collider2D collision) (at Assets/skrypty/ExitThisLevel.cs:22)

i tried his two comends:
timer.addPoints();
GameObject.Find("GameMenu").GetComponent<TimeManager>().addPoints();

[lean estuary]

@zenith saddle It doesn't find TimeManager component on GameMenu object, and calling method on a null object triggers the error. You should always use direct references when you can to avoid that.

[zenith saddle]

Right

But I trying fix this and I can't come up with

ok, i have right 😄

I should find Timer, not GameMenu 😄

and Timer is in GameMenu

Hey, Im planning to make a game like Terraria for educational purposes, but the world design will be created on the Editor using tilemap(not procedural). I would like to get some advice before commiting to much into it. Is it going to be expensive (to the point of being unplayable) on the computations if I have the entire world loaded and rendered at once?

[clear tusk]

@leaden veldt you will need to instantiate the prefab first then do something like this.

GameObject objectToColor;
 objectToColor = Instantiate (....);
//This method is going to be assigned in the inspector of the button OnClick event or use it with code.
Void changeColor(){
 objectToColorkubus.GetComponent<Renderer>().material.Color = Color.red;
}

[sterile timber]

Hey everyone, me again. I've been searching for weeks about ordering but couldn't find anything that would point me to a direction that could help with the issue I've described here https://forum.unity.com/threads/sorting-sprite-renderer-over-a-mesh-renderer.1029448/

TL;DR from the forum link:
I have a sprite renderer with billboard and a 3d mesh is culling part of the sprite. Sorting layers don't seem to work neither sorting groups

[copper stump]

@sterile timber what does the 3d scene look like? the character sprite is intersecting with the geometry I assume?

also this might be of interest

https://forum.unity.com/threads/3d-object-mesh-behind-a-sprite-sorting-layer.453692/

bgolus has a good breakdown of the respective rendering techniques

[sterile timber]

Well, I was searching a bit more and found out that if I keep my sprite straight and change its Y scale based on the camera angle I can achieve the billboard effect

the sprite intersects with the mesh

[copper stump]

an interesting solution, I had something similar set up and rejected it eventually because it created more issues than it seemed to solve further down the line

I assume before you had the sprites angled to align with the camera?

hence the clipping

[sterile timber]

exactly

the billboard just copied the camera's rotation

Ive also tried bgolus shader as posted here https://forum.unity.com/threads/problem-solving-2d-billboard-sprites-clipping-into-3d-environment.680374/

it sometimes makes the sprite disappear

however it fixes the clipping

[copper stump]

interesting

A screen facing sprite already has the same z across the entire surface, that’s in fact kind of the problem.

how did he solve this?

stenciling?

[sterile timber]

not sure what stenciling mean

[copper stump]

nvm, I guess if what you have working now works then cool. I'd love to work out the shader code to do this:

The even more advanced shader only option would be to output the z as if the sprite is a vertically aligned sprite, but keep the appearance of a screen space sprite.

as it seems to be the most 'correct' solution

and makes sense logically but for the life of me I couldn't write that

some sort of vertex shader manipulation I expect

[sterile timber]

well, the project im working is open source

feel free to contribute xD

[copper stump]

😉 oh god, don't get me started on another project

[sterile timber]

a shader won't kill 😇

[copper stump]

also - does anybody know much about velocity Verlet integration who could answer a couple of questions I have?

[ocean raft]

The new input system seems to not fire an event for the second key in a combo of two keys, both of which are assigned the same 2DVector Action. Is there official documentation somewhere that explains how to use the 2DVector action bindings?

[solemn latch]

@sterile timber can you use a vertical billboard but project the texture onto it in screen space so it faces the camera even though the geometry isn't?

[sterile timber]

I think I've done that on my last try. The X rotation isnt touched anymore. Instead I increase the Y scale by 1 + cos(angle)

[cold bloom]

How could i clamp the camera to perfectly collide with a exact coord?(blue line) Depending the resolution i can see out the "map".
It matches correctly top/bottom but left/right nope...

Noticed it maches at 1920*1080, how could i do it it matches on every res?

I'm trying to do a basic floor detection but I'm getting a strange issue where the OverlapCollider seems to detect overlap before it should. (added gif with visual)
Code to do detection:

   void FixedUpdate()
   {
       //Reset value
       isLanded = false;

       //Do cast to see if any collisions are present
       Collider2D[] hit2D = new Collider2D[8];
       int floors = collider.OverlapCollider(contactFilter, hit2D);

       if (floors > 0)
           isLanded = true;
   }

What am I doing wrong?

[still tendon]

Hello, what is the preferred way to apply a force to a UI element (button)? I would like the menu to "fly away" after clicking "start game".

I tried to add a collider and a rigidbody to the button but it doesn't seem to do anything

(there's an area effector below which works fine with other game objects)

[magic rapids]

On a UI element? :\ I'd say either make it a sprite or use an animation/tween in script.

[still tendon]

how would i make it a sprite?

[magic rapids]

Place a sprite in the world with a 2Dbox collider on it then use
void OnMouseDown()
{
// do stuff
}

may want to make it a trigger collider unless you want it to interact with stuff

[still tendon]

ok so it's basically creating a button from scratch

thank you for your advice, i will evaluate this option

Fixed: setting navigation to none in the inspector did the trick.
Original question: Is there a quick way to stop a button from getting clicked on by the space bar?

[brittle lagoon]

Something like this

Or

previousposition this variable is going to be a vector 2 and it will have the last position that player was in before it falls of

[cedar panther]

So I'm trying to compare the edges of my sprites to find the closest possible match to my tiles

so I go along the edge of each sprite pulling the pixels that line up with the next tile

and get the absolute (pixelA - pixelB)

then I add that all up and get the difference value

and find the tile with the lowest of this value

it doesn't work very well

anyone know of a better way?

[opal socket]

Do you have to work on pixels? Why not Unity Units and scale?

[nimble pewter]

Ok so I have several objects in my scene setup so when I click them a UI panel pops up with information about that object. I've gone with the simple method of a script attached to the object that opens its UI. The problem now is my info panel UIs end up opening on top of eachother... I know there is likely a more efficient way of handling this rather than placing "Set.Active(false);" on every single object's interaction script...

I've gotta gather there's a way to have one script that handles opening and closing UIs for all specified objects, just not sure how to set that up

[cedar panther]

@opal socket unity units and scale?

I'm trying to find the closest match for a given tile out of my tileset

it's not an issue of positioning, it's an issue of finding the appropriate tile that fits next ot it

[opal socket]

Ahh sorry misread

[urban tusk]

can someone help me figure out why this isnt detecting collisions
isGrounded = Physics2D.OverlapCircle(groundcheck.position, .2f, WhatIsGround);

[plush coyote]

Not without more context

[plush coyote]

1. Have you initialized WhatIsGround to your desired layers?
2. Is your ground object actually set to the ground layer?
3. Is the groundcheck in the correct position, and a child of your character?

4. is .2f actually enough radius to touch the ground from the groundcheck's current position?

[urban tusk]

I've realized my stupidity, i created the layer and then never assigned it

[plush coyote]

Honestly, that is an easy mistake to make

In my opinion, creating the layer should automatically assign it to the object you just created the layer on

but it doesn't.

Is there some scaling of the texture I have to consider?

nope that's not it, I'm actually getting pixel values that don't even exist in the sprite

[tropic inlet]

Yeah, that sounds like what he's prolly doing

@earnest trail make sure u don't modify the y

[earnest trail]

Let me check

[cedar panther]

these getpixel values don't make any sense

[earnest trail]

I mean im a beginner so im looking online mostly for code

[tropic inlet]

Vector2 vel = rb.velocity;
vel.x = Input.GetAxis("Horizontal") * speed * Time.fixedDeltaTime;
rb.velocity = vel;

obviously, input shouldn't be taken in FixedUpdate

[earnest trail]

My previous movement with wasd was really nice but because its on android i changed it to using arrow keys and changed the whole code to something very simple

[tropic inlet]

but this is the basic idea
u should only change x from horizontal movement

[earnest trail]

Ok one sec

im using this:

void Update()
    {
        if (moveLeft)
        {
            rb.velocity = new Vector2(-moveSpeed,0f);
        }
        
        if(moveRight)
        {
            rb.velocity = new Vector2(moveSpeed, 0f);
        }
    }

[tropic inlet]

see, that 0f is the problem

[earnest trail]

isnt that 0?

[tropic inlet]

u are setting vertical velocity to 0

[earnest trail]

oh

How could i do it so it doesnt change?

[tropic inlet]

replace each 0f there with rb.velocity.y

[earnest trail]

hm ok let me see

ah its perfect now

Is there any tutorials to explain a bit these vector2 vector3 , rigidbody etc? Because ive seen a million ways people use to code something and its confusing which one i should use every time

Speaking for unity

[tropic inlet]

to understand vectors, I recommend this video

sec

[earnest trail]

Also i have 2 more minor issues if you can help

[tropic inlet]

https://youtu.be/e3z91RqZPAk

a vector can be one of two things:

1. a position
2. a direction

[earnest trail]

hm

[tropic inlet]

rb.velocity is a direction vector

transform.position is a position vector

[earnest trail]

Il check the video, thanks!

For 2d both conern me ?

[cedar panther]

yes

[earnest trail]

both position and direction right

[tropic inlet]

yes

[earnest trail]

aight

Ok i have another minor issue. Im using a background and some assets ive found to create the environment

my player is a ball

when i move it

the background does like little vertical lines

sometimes

its really minor but its noticable

its lines as if the background tiles are not correctly connected or something

like those lines from old movies

[stark trellis]

i have the same issue but with vertical lines, i was wondering if it's the tilemap not updating in time when the camera moves

[cedar panther]

probably don't have the camera setup right

[earnest trail]

im using that cinemachine camera

wait let me see if i can get a video

[cedar panther]

It's a common issue, I don't know of a good tutorial on it, but you need to make sure your camera , pixels per unit and so on are all in line with each other

[earnest trail]

hm so its a camera issue

Awesome il take a look at it. Also something last. Is there a way to change the collision box of some tiles?

As you can see the collision is a bit above

[cedar panther]

I haven't mucked with collision yet, but it should be editable

[earnest trail]

alright, thanks.

[stark trellis]

@earnest trail i've found an answer to the flickering tilemap in here: https://www.reddit.com/r/Unity2D/comments/8g74ft/tile_flickering_problem/

[earnest trail]

Thank you. I was looking right now for a while and couldnt find anything

Let me check it

People say about this pixel snap but i cant find it anywhere

[cedar panther]

no thoughts on the getpixel issue?

[earnest trail]

Getpixel?

[cedar panther]

yeah I'm running into weirdness when comparing pixels in sprites

[earnest trail]

Whats getpixel?

Il try adding border on the tiles

Maybe this will fix it

nvm

[earnest trail]

So whats the approach on level making? Should i make some variations and make it so it randomly adds to it? Because im thinking something like hill climb racing where its a big horizontal level and you upgrade a little bit your stuff so you can go a bit further every time

[cedar panther]

those hill climb distance games usually don't have random terrain features

because if you do then how far you get is purely dependent on your luck, rather than getting a little farther each time you get upgrades

the other styles of the game do have randomality (like the ones where you shoot something out of a cannon, or have something that fly's) so I guess it could work

the easiest might be to define "sections" of map that you randomly decide one after another

[stark trellis]

@earnest trail i kind of fixed it, my tiles had Pixel Per Unit = 128, i changed it to 127.5, re-created tileset, re-painted the tilemap.... and now the lines are gone. My only concern is if this will impact the rest of the level design and/or the tilemap colliders

[cedar panther]

yeah not sure you want to be shaving off a bit on pixels per unit

that sounds like a headache down the road

[earnest trail]

Crap, haven't thought of that. You're right

[stark trellis]

yeah that's my worry, better a whole pixel?

[earnest trail]

I gave up for today. Wasted like an hour but couldn't fix it

[cedar panther]

you might need to use the pixel perfect camera

and look up a tutorial on how to determine the settings for it

if you get the settings just right it should tile everything without issue

[stark trellis]

i'm using the CinematicVirtualCamera, is that the same of the pixel perfect camera?

[cedar panther]

no

@earnest trail If you make sections (like how the level editor works in the NES game excitebike) and then make a determination of the difficutly of a certain section (how much fuel it costs to pass and such) you might be able to come up with a system to randomly generate the level in a way that doesn't lead the player to having drastically randomized drive distances.

[earnest trail]

Im using that too

And took me a while to fit it to the level

So it doesnt go outside of the level

[cedar panther]

Sometimes it's ok to have a bit of the sprites go off the sides of the level

[earnest trail]

No i mean that it was displaying parts where there wasnt tiles

So it was really ugly

[cedar panther]

ahh

well that's dumb

sprite.texture.getpixel is the whole texture

so I need to use the rect for the spritesheet to get the right position

[cedar panther]

Is this right?

Color32 pixel = texture[rect.y + yPos * rect.width + rect.x + xPos]

[valid dune]

Vector3 mouseScreen = Input.mousePosition;
Vector3 mouse = Camera.main.ScreenToWorldPoint(mouseScreen);
transform.rotation = Quaternion.Euler(0, 0, Mathf.Atan2(mouse.y - transform.position.y, mouse.x - transform.position.x) * Mathf.Rad2Deg - 90);

help not work

im instatiating character 4 seconds after a procedural level is made player not rotating to face cursor

help

[ocean raft]

The new input system seems to not fire an event for the second key in a combo of two keys, both of which are assigned the same 2DVector Action. Is there official documentation somewhere that explains how to use the 2DVector action bindings?

[elfin sandal]

best documentation you'll find is on unity's site but it's not easy to understand

[modest cairn]

I feel like I must be doing something wrong

I've got two box colliders set up, one is a trigger one isn't, when they overlap the trigger has some code on it in void OnTriggerEnter2D to make it do Debug.Log calls but nothing is happening

nope, it needs one?

I'll try

yeah it needs one

in my head, I'm like "don't do that, you don't need physics objects"

but I guess it's fine

[valid dune]

if i deleted my main camera can i make another using the main camera tag

hmm

ok im having problems with my character facing the cursor and thats not it

could it be that the update function is bugges

bugged

because it faces a point when its spawned

Vector3 mouseScreen = Input.mousePosition;
Vector3 mouse = Camera.main.ScreenToWorldPoint(mouseScreen);
transform.rotation = Quaternion.Euler(0, 0, Mathf.Atan2(mouse.y - transform.position.y, mouse.x - transform.position.x) * Mathf.Rad2Deg - 90);

thats in the update function

its not updating the mouse cursor

it thinks its at a point

hmm indeed

hahah ok

got it

its saying 00

but

its supposed to rotate on the z axis anyway

ill change the code

-0.70710680

thats what its returning

well debugging the mouse position seems to return the mouse position

Vector3 mouse = Camera.main.ScreenToWorldPoint(mouseScreen);

i think the problem is here

i dont think it has a reference to Camera.Main

no it does

hmmm

2d

[tropic inlet]

i don't think printing the .x of a quaternion will be very useful

unless u can actually interpret them

they are some complex 4-dimensional representation of rotation

i see

quaternions are complicated af, yea

that's why

.eulerAngles exists

easier-to-understand three-dimensional representation of rotation

[valid dune]

vector2 isnt it

i have been

haha all good

its not that

i debugged that

Quaternion.Euler i think its already using that

im sure its something about the project/not code

it was working b4

but i dont know what happened i literally changed a script to mess with procedural spawning and it stopped working

i think i found a key to the puzzle

mouse isnt updating

got it to work

the method used is screentoworldpoint

and that needs a specific z value set in order to see at which point of the ray cast from the camera to u se

thanks for the help boys

[still tendon]

[smoky loom]

So i need help for jumping when i jump multy times its jump multyple times . i want that when you jump it wait 3 second

but i dont know how to do it

here my code

I CANT PUT MY CODE

AHHHHHHHHHHHH

[lean estuary]

@smoky loom Code posting guidelines are pinned in #💻┃code-beginner

[smoky loom]

ahhh thx

So i need help for jumping my probleme of the script is that when i jump multyple times its jump multyple times . i want that when you jump it wait 3 second
but i dont know how to do it !

Thats my code (There is the movement code to)

[tropic inlet]

You want to deliberately implement a 3-second delay prior to each jump?

decrease a float in update or use a coroutine

[smoky loom]

yes i want to do it

[smoky loom]

i dont understand

[ruby karma]

when you jump, set a float to 3.
Each frame, subtract Time.deltaTime from that float.
Only allow to jump if that float is <= 0

[smoky loom]

i dont understand try to show me a script

[ruby karma]

Which part do you not understand? I can give you a script, but there's no point if you just copy it

[smoky loom]

all of it that i dont understand

im not a pro of coding all i do is following tutorials

[ruby karma]

private float timer = 0f;

private void Update()
{
  if(timer > 0f)
    timer -= Time.deltaTime;
   
  if(timer <= 0 && isGrounded && Input.GetButtonDown("Jump"))
    Jump();
}

private void Jump()
{
    //Perform jump
    timer = 3f;
}```

[smoky loom]

and where shuld i put it?

[ruby karma]

ok, now you need basic unity/c# tutorials

if you do not understand that

[tropic inlet]

it's a good idea to learn programming basics before doing gamedev

it was laid out in a pretty easy-to-understand way

[smoky loom]

Ok!

[tropic inlet]

console apps are the best learning environment

[gloomy stream]

I have this code to be able to move my character everywhere I want, and it worked perfectly fine. But I decided to move my character only left to right so on the x axis. Once I remove my y axis code, it doesn't work since vector2 doesn't have another float. Any help?

[stark trellis]

just change newYPos to transform.position.y this way you don't move the Y position

i go by memory but isn't transform.position.x just a getter? You cannot modify it directly

yeah it's just a getter, cannot modify it directly. But if you don't want to allocate a new Vector at every Update you can have one global Vector in the class and use Set to change the values on Update

[gloomy stream]

It worked, thanks :)

[valid dune]

im trying to do a camera script that moves the camera to a empty on rooms of a dungeon

i just cant get it to work

the script is on the camera btw rn im just trying to have it follow the player

[shell wadi]

excuse me, I'm having some issues related to the jump movement in my game

as you can see, this is my RigidBody

my character script settings

the issue is when I jump it ascends with great speed, however, when he falls, he does slowly

https://pastebin.com/EZZgeG8Y here is my code. If you could help I would appreciate it greatly.

[clear tusk]

@shell wadi if the issue is the slow falling you just need to play with the linear drag and gravity scale in the project settings.
For the jump speed make sure you are multiplying with the time.deltatime or time.fixeddeltatime if you are using physics and make sure all that is inside of the fixedupdate

[shell wadi]

all right, thank you very much

[valid dune]

anyone have any ideas why my code isnt working

[tall current]

@valid dune what exactly do you want your code to do?

I'd say, make sure that there are no nullreferences.

Using GameObject.Find() like that isn't usually a good idea

[valid dune]

Well it's just trying to set the camera position to the player position with an offset on the z

Should've commented out the first two lines in start

You think the null references are the problem?

[fleet lily]

how can i make a gif sprite, i have the gif i want to use but i don't know how to use it

[valid dune]

you have to make a spritesheet

the problem on my code was i was running 2 coroutines at the same time and having them end at the same time setting a bool to true before the camera script could do anything

[runic pawn]

Hey, I've been having an issue with Physics2D.IgnoreCollision, as it is not properly ignoring the collision. I'll send a pic of my code.

I actually print debugged the values the ignore collision returns and as far as I could tell, they should be good.

One weird quirk I noticed is that if you apply velocity to the rb after IgnoreCollision line, the bullets will actually move through each other properly however it will still have the initial collision halting velocity.

So some context: 2 players shoot bullets at each other, and the bullets should travel through each other but it seems on intial impact, it just halts the velocity due to the collision, but it seems the ignorecollision does work right after they collided.

Like there seems to be like a singular frame where the collision happens before any of the code applies.

Alright I managed to fix it by messing around with different things, I ended up making the bullets "triggers" and used OnTriggerEnter2D instead. But I still don't understand why the one works over the other, so I would still appreciate if someone could explain that to me.

[tame lark]

Hello. I need some help with 2D coding. I have a object parent and a bunch of child objects and I want to be able to setup the index of each child, any idea how I can do that?

[lyric oriole]

How do you setup 2d player controls like moving around. I am making a platformer game btw.

There are like a million tutorials for that.

Hey I am new on this discord and have a problem with an prefab-spawner using the "instantiate" command. Everytime I try to load the prefab a "Index was outside the bounds of arry"-Code appears. Can someon tell me, what this means and how to fix this problem?

[karmic storm]

this is the full error code

[tropic inlet]

it's saying, on line 17 in your Spawner.cs script,

you tried to access an index beyond the bounds of your array

e.g.,

int[] arr = new int[3];
print(arr[42]);

arr[42] in this example is way out-of-bounds

there is only arr[0], arr[1] and arr[2] because arr is of size 3

@karmic storm

[karmic storm]

Hmm seems strange. I checked all of the code but I think this shouldn't happen.

Can I send you a screenshot of the CS-code?

[tropic inlet]

It'll be easier if you used either hatebin, Pastebin or Github to paste the code as text instead of a screenshot

but if the code is small enough, yea, a screenshot would work

[karmic storm]

Oh okay. I forgot to change a value in the unity interface. Finally solved it but thanks for help :)

[rigid juniper]

I am having a bug right now where in my game which is a top down shooter where the bullets get instantly destroyed if the player is shooting downwards

Ive checked my code I dont exactly know what is causing it

If someone could help I can share my code if you want

[rigid juniper]

Oh wait no I figured it out!

The bullet is colliding with the players hitbox!

So I guess now the question is, how do I make it so the bullet doesn't collide with the player?

But I still want the player to be able to collide with obstacles

[runic pawn]

@rigid juniper Look into Physics2D.IgnoreCollision stuff

you should be able to do that on creation/collision detection

you need both objects to have a collider and you'll need to be able to access them both

so for example in the player control script you could do like:

var bullet = Instantiate(...);
Physics2D.IgnoreCollision(GetComponent<Collider2D>(), bullet.GetComponent<Collider2D>());

[rigid juniper]

Ok thanks!

[fleet lily]

you could i make my object point to mouse, is there a .pointTo function

[rigid juniper]

https://youtu.be/LNLVOjbrQj4 This video makes the player point towards the mouse, so you could just apply that to whatever you want to point towards the mouse

[tropic inlet]

I could make a function for u

void PointAt(Vector2 target){
  Vector3 dir = (Vector3)target - transform.position;
  dir.z = 0;
  transform.right = dir;
}

or

void PointAt(Vector2 target){
  Vector3 rot = transform.eulerAngles;
  Vector3 dir = (Vector3)target - transform.position;
  rot.z = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
  transform.eulerAngles = rot;  
}

haven't tested

[viral salmon]

Hey! I've made top down shooter, and it works like the video above. My problem is that I've added screen shake to my game, but the thing is that the screen shake changes where I'm pointing at. I want for example be able to continuously shoot straight, but the screen shake makes me shoot wobbly. Any ideas how to fix it?

[tropic inlet]

Spawn the bullet before invoking the screen shake?

oh w8

hitscan or projectiles?

[viral salmon]

projectile

i was thinking of getting the screen shake camera offset and just subtracting that from the mouseposition

lets say that when the screen shakes my camera moves 1 unit to the right, what i would do is just subtract my mouse x-position by 1

I'll try my solution but I have no idea how to do it.

https://gyazo.com/840bdae92a1db586dae4e643b3af569a

Here's a gif of my problem

[rigid juniper]

Something that might work although idk exactly how to do this is to make the mouse an in game object that moves along with everything else when the screenshakes

[viral salmon]

That's the problem though, I think. When the camera moves to the right due to the screen shake that also means that my player aims to the right, which is not intended.

[rigid juniper]

Well what Im saying is make the mouse move with the screenshake as well

because the reason the player's aim is wobbly is because the player is moving during screenshake and the mouse is not

So if the mouse moves as well it should be fixed

[viral salmon]

Wait, think you're on the right track, but it should move the other way from the screen shake offset

[rigid juniper]

Well you wouldn't want it to be opposite because then it will just make the bullets wobble more

[viral salmon]

Let's say I move the mouse with the camera and just spray, that means my mouse will follow the camera which is shaking, which means that my mouse in turn will shake, which will make my aim shake.

[rigid juniper]

The aim wouldn't shake if both the mouse and player are moving the same amount

[viral salmon]

but I dont want my character to move, do you mean my camera?

[rigid juniper]

Well yeah I do mean the camera, what I'm trying to say is your mouse isn't affected by the camera but if it was then you wouldn't have wobble

[knotty barn]

Offsetting the aim seems fine.
Cinemachine has more of a pipeline structure where some stuff is calculated at different times and values are kept track of.

[viral salmon]

My mouse is affected by the camera though

Whenever my screen shakes my projected mouse position changes

[brittle lagoon]

i want to have a certain limit to which if a player passes that limit he respawnscan someone give me a step by step turotial

[tropic inlet]

huh

So, @brittle lagoon, you have two questions, right?

1. How to make the ground move up and down.
2. How to make a player respawn if he travels beyond a certain area.

Correct?

[nova coyote]

Whats the best way to make a sprite flash white to show damage? I understand the coding aspect, but I dont really know much about materials/shaders or anything like that

Making new sprites that are white and replacing the original sprite with them isnt a great option because there are a lot of animations

[mossy bough]

@nova coyote are you not just able to change the sprite's color property?

[nova coyote]

What i settled on was changing the spriteRendered color to red, which works

but the fault color of all sprites is white, so changing it to white just makes it the default color

hii i need help

Does anyone have a video tutorial on how to make a gui to dress your character in unity? I need it urgently, I can't find anything to help me on YouTube, my English is very bad, I'm using a translator

[crystal isle]

I'm having trouble with unity's 2d animator system, i am following a 2d platformer tutorial (from MuddyWolfGames) and although i followed the tutorial exactly, there are no animations playing. After checking the animator tab while running the game, i see that the animations are just not triggering. I am a beginner in all of this and don't really know what information i should be providing rn, so sorry about that

[coral nest]

@crystal isle you can activate animation through code by

setting the animation to activate through certain parameters using the unity interface

[coral nest]

It's complicated your better off paying a person to help you. Or learning step by step until you know what you're doing.

[coral nest]

Your coroutines aren't doing anything.

[coral nest]

Is your script on the player?

Cause I used your code it and worked just fine.

[still tendon]

how do i check which position is the player looking

[coral nest]

local space

relative to global space

thats how you know

if you want a easy way though... you can attach a object to its front

[fleet lily]

how would i get the difference of one object to its self
i want to get an enemy to always fly to your character

[coral nest]

so you know which way its facing @still tendon

[coral nest]

distance formula

[fleet lily]

can i get that

[coral nest]

or wait was it distance formula....

its been a while lmao

its enemy position - player position

if its enemy to player

else its player - enemy

[fleet lily]

'GameObject' does not contain a definition for 'position' and no accessible extension method 'position' accepting a first argument of type 'GameObject' could be found (are you missing a using directive or an assembly reference?)
for this

      Vector3 difference = you.position - transform.position;

@coral nest

[coral nest]

transform contains it

gameobject.transform.position

[fleet lily]

ok

now how can i make the characters be able to go through each other but not walls

[coral nest]

remove collision from one layer and put them on it

or make them ignore objects that are tagged player

[rigid juniper]

Is there a way to make an object have a randomly chosen texture?

For example I have a rock in my game but I have drawn like 8 different versions and I want each rock to have a randomly chosen one of those versions

Would it just be easier to make 8 different rock objects and randomly choose from them?

[leaden flame]

@tropic inlet ew you

you probably want [SerializeField] private GameObject death; ;)))

[blissful shuttle]

Hello, this code worked for me on other projects, but for some reason, it doesn't work in some cases (and I don't know what's causing the issue.)

This code throws the Null Reference Exception error:
(the error comes from returning the GameObject in the function)

    void Update ()
    {
        if  (Input.touchCount > 0)
        {
            Debug.Log(TouchingObj());
        }
    }


    //Return Touching Object
    GameObject TouchingObj()
    {
        //Shoot ray
        RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint((Input.GetTouch(0).position)), Vector2.zero);
        //Return gameObject
        if (hit.transform.gameObject == null) return null;
        return hit.transform.gameObject;
    }```
Could someone point out what's the problem?
Thank you so much!

[tropic inlet]

hit.transform can be null

since Transform is a reference type

[blissful shuttle]

Thank you so much!
Could you share how I can fix it?

[tropic inlet]

return hit.transform == null ? null : hit.transform.gameObject;

@rigid juniper are you able to store a texture in a variable of some sort?

I've never done it, but the basic idea could be

[SerializeField]
private Texture[] textures; //set in inspector

private Texture texture;
private void Start(){
  texture = textures[Random.Range(0, textures.Length - 1)];
}

[blissful shuttle]

Thanks! It worked 🙂

make sure the tag is uppercase

it is case-sensitive i guess

    private void OnCollisionEnter2D(Collision2D collision) {
      Debug.Log("1");
      if(collision.gameObject.CompareTag("Enemy")) {
        Debug.Log("2");
        Destroy(gameObject);
        levelManager.instance.Respawn();
      }
    }
}

This is on the player

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

public class levelManager : MonoBehaviour {
    public static levelManager instance;

    public Transform respawnPoint;
    public GameObject playerPrefab;
    private void Awake() {
      instance = this;
    }

    public void Respawn () {
      Instantiate(playerPrefab, respawnPoint.position, Quaternion.identity);
    }
}

and this one just floats on an empty thing

[distant pecan]

the destroy should be the last thing it does, or the object will be destroyed and this line won't be called at all:

levelManager.instance.Respawn();
