[still tendon]

Ditto, Scene view

And the inspector

Everything else is ordered at 0 on the default layer, and the background is at -100 on the default layer

I could pull a hacky thing we use to prevent the arms and the gun from clipping in 3d games, but I feel I'm just missing something obvious here

Thanks!

[wide ledge]

so do i use Brackeys Character Controller 2D or code my own?

[abstract olive]

Either?

[dusky wagon]

Any idea why my sprite looks like this normally

And like this in unity?

[late viper]

change filtering to point

[dusky wagon]

Filter mod is already set to Point (no filter)

[late viper]

turn off compression maybe?

[dusky wagon]

Ah that was it

Im confused because it worked before

[drifting warren]

hi im having a little problem where i use a tilemap collider 2d and a raycast to detect the tiles but it doesn't seem to work

the line is the raycast and the sphere is the hit position

it should be on the tree, but it isn't

and in the position it won't register it

hit = Physics2D.Raycast(transform.position, P1.position);
        

        if (hit)
        {
            print(hit.collider.name);
        }

nvm i found the error

[compact cave]

Hi everyone. Im having a problem. If I hover over a button then the bacground changes but I have another button where it doesnt the only difference between the 2 buttons is that one of them has a default UI material and I don't know how to apply it to the other button.

Anyone? Sorry I'm impatient

[plain mortar]

Not sure if this will solve your problem. Looks like you might be missing shaders. Check the project/graphics settings to add them to the "always include" list

[light perch]

Hey, how do I change my background here ? I want to either draw it myself or use a program for PixelArt (both digitally oc)

[light perch]

Where did you get this nice Palm Tree from ?

[drifting warren]

it's a 2d asset i found on itch.io, here's the link!
https://stealthix.itch.io/rpg-beach-tileset

[light perch]

Thanks

Can you help me with making my own background ?

[drifting warren]

im not a very good artist unfortunately

[light perch]

My question is more HOW I do that

So how do I use a e.g. PNG as a background

Or whatever type of file

[drifting warren]

you can use the tilemap to put your background

essentially, you bg is a sprite

[light perch]

Ah, ok

I just found a weird bug

[drifting warren]

be sure to put the order in layer at a lower value tho

[light perch]

My character (currently a capsule) can go through walls but not the ground

[drifting warren]

or else you may end up with some weird back and forth graphics

[light perch]

🤔

[light perch]

Alright, ty

[drifting warren]

does your wall have a collider?

[light perch]

Yes

Its basically a copy of the floor

[drifting warren]

hmm

[light perch]

But with a different size

[drifting warren]

check the collider dimensions

sometimes when scaling the object, the collider doesn't

[light perch]

Ok...

Well how do I see ?

Well sizes already seem to bug here

When I set the EXACTLY SAME coordiantes for a wall and a ground obstacle

They are somewhere completely different

[drifting warren]

that button

[light perch]

Looks normal

Well I use 3D colliders everywhere rn btw

[drifting warren]

is your wall or ground obstacle a child of an empty gameobject?

if so, check that the empty gameobject is at 0,0,0

[drifting warren]

2d colliders are preferable

[light perch]

Both a children of something different. Walls: children of "Walls" Ground: Obstacles of "Ground" "ground" and "walls": children of "obstacles"

[drifting warren]

hm

[light perch]

Oh, so. so the position of an obstacle is relative to its parent ?

[drifting warren]

you should check that all of those empty gameobject parents have 0,0,0 as position

[drifting warren]

exact

[light perch]

Wall:

Ground:

See ? Both parents are at 0,0,0

But their positions dont really match (even not x, they are literally on top of each other)

[drifting warren]

hm

[snow willow]

the position is the position of the center of the objects

[light perch]

Anyways, collider thing is fixed for some reason now idk why

[snow willow]

because that's where the pivot of the mesh is

[light perch]

But their width is the same

[snow willow]

they must have different parents

[light perch]

They do

[snow willow]

yes

and the position you see is relative to their parent's position

[light perch]

Both parents are children of "Obstacle" (an empty game obj)

Both parents are at 0 0 0

[snow willow]

show?

show the hierarchy

and the transforms of everything

[light perch]

At least I thought that. Position of one parent didnt save idk why

[light perch]

Ok

SO If I have a cube Width the dimension: 1 1 1 at the pos 0 0 0 and another obstacle with the dimensions 1 8 1, how high do I have to set it so that they are PERFECTLY on top of each other ?

[snow willow]

ok so you figurd it out right

[light perch]

Yee, thanks

[snow willow]

you need the bottom of the 1, 8, 1 box to be .5 units above the center of the 1, 1, 1

so whatever the y position of the 1, 1, 1 is, add 4.5 to that

[light perch]

CLose...

Wait

[snow willow]

is the scale of any of the parents not 1, 1, 1?

[light perch]

WHY is the scale NOT 1 1 1 anymore ?!

[snow willow]

you may have reparented some things to some other non-1, 1, 1 things

which can adjust their scale

[drifting warren]

tip: as a rule of thumb, whenever you create a gameobject, whatever it is, rightclick the transform and reset it

it will prevent you from further headaches

[light perch]

To fix this now: How do I change the scale of all children ? (all cubes must be 1 1 1 but are 1 0.9843 1)

[snow willow]

Or do yourself a favor and enable this:

[light perch]

Hm, alright

[snow willow]

select all of them and set the scale to 1 1 1

you can select them all at once and do that

[light perch]

Thanks

[light perch]

Hold shift in hierachy, right ?

[snow willow]

shift to select a range of things, control to select multiple individual things

[light perch]

AHH, perfectly aligned, as all things should be

[light perch]

Thanks

[lost phoenix]

i kind of need help
im making money for my 2d game and ive run into a problem

i got an error saying
Cannot implicitly convert type 'int' to 'UnityEngine.UI.Text'

[knotty barn]

Seems like your coinDisplay is an text object, not the value

[lost phoenix]

oh

[knotty barn]

Text objects do have a text property, which you are probably looking for

[snow willow]

coinDisplay.text = "5";

[lost phoenix]

o wait i got it

if your talking about the value it would mean my coin count

it worked

thanks

[jolly hawk]

How can i make a multiple clicking required to perform certain task?

[snow willow]

keep track of how many clicks have happened in a variable

when you reach the desired number of clicks, do the thing

[jolly hawk]

Ok, but It is lifting weights game, i want to make each click lift weight just a bit and multiple to complete lift

[snow willow]

Ok, but my advice remains the same

whether it's a cooking game, lifting game, ice cream vendor game, FPS game

[jolly hawk]

Thanks I will take your advice

[dusky wagon]

How can you access the Rigidbody2D of a Collider2D?

Im using void OnTriggerEnter2D(Collider2D col)

[turbid heart]

you have a reference to the object with the Collider2D, just GetComponent from it

[dusky wagon]

How does that work?

[snow willow]

Rigidbody2D theRb = col.GetComponent<Rigidbody2D>();

[turbid heart]

you are intending to get the rigidbody of the col object, right?

[dusky wagon]

Yes

[turbid heart]

well, there

[dusky wagon]

I want to add a force to the rigidbody of the collision object

Alright thank you very much

[snow willow]

Just to help clarify @dusky wagon what's happening is like this:

You have a reference to the COllider2D. To get any other component attached to that same GameObject you can call GetComponent<something> on any of those components and get any of the other components that are attached to the same GameObject

The GetComponent call basically does what this red arrow does. It goes to the GameObject and says "give me your Rigidbody2D component, if you have one"

[dusky wagon]

And what is Transform?

[snow willow]

another component on the GameObject

the one that determines the object's position, rotation, and scale in the world

[dusky wagon]

Ah okay thanks

[snow willow]

every GameObject has a Transform component

all other components are optional

and you can have any number of components on a GameObject

[dusky wagon]

I also have a completely different question

My Character sometimes looks really weird when moving. the Sprite doesnt fly smoothly but looks like it always stands still for a very short while and then teleports to the position of the object, any idea why?

I dont know if this is the kind of question you can answer without knowing the code or if there is any further information needed

[snow willow]

definitely not a question that can be answered without knowing the code etc..

[dusky wagon]

I have a cinemachine attached to the player

And it doesnt always happen only sosometimes

Im trying to test when exactly it happens

It seems to happen when I get launched through a one-way-collision collider that I made with a platform effector

Nevermind it does not

I will test if it happens because of the cinemachine

[jolly crest]

can you change universal render pipeline lighting with c#?

[snow willow]

yes

[jolly crest]

how

[snow willow]

what are you trying to chagne

[dusky wagon]

It does seem to only happen with a cinemaching but it might be better if I leave it until I know more about unity because I have no idea how to test when and how it happens right now

[jolly crest]

radius and color

[snow willow]

raidus and color of what

[jolly crest]

lights

a point light 2d to be specific

[snow willow]

[dusky wagon]

How can I use this to get the Gameobject itself?

Wait I might have found it

[modest rivet]

How would I make a 2d sphere get vertically forced up, for example flappy bird?

[hasty steppe]

This is what I used to make a enemy jump towards a player as an attack

enemyRB.AddForce(new Vector2(distanceFromPlayer,jumpHeight),ForceMode2D.Impulse);

Im sure you could modify this string to do just a straight up vertical movement

[modest rivet]

Ty

[silent spindle]

Has anyone anyone got any good scripts or knows any tutorials for 2D rigged weapon aiming? I want my rigged characters armCannon to follow the mouse and be able to shoot. Or aim at different directions while shooting, but still retaining the run animation, similar to cuphead.

i have an issue with setting up a camera script . details --- https://hastebin.com/vevecicenu.csharp

[umbral cape]

You can just use ik. There are lots of tutorials on it

[last jasper]

Hey I need a little help with my code

[bronze estuary]

how do I flip a sprite from the center of the collider instead of the center of the sprite?

when I flip the fella he moves further to the right

[wide ginkgo]

Crop your sprite to not have dead/empty space

[bronze estuary]

im using that space for extra animations though

like an attack animation

[wide ginkgo]

Well you can't flip it internally, so you would end up flipping the entire bounding box, is that fine?

[bronze estuary]

yes

[wide ginkgo]

I think the only way to do that would be with some manual math

[bronze estuary]

i thought I flip it and move it rq so it doesnt matter

[wide ginkgo]

Get the distance from center of Bounding box, perform a flip, then move the character to the left/right by that distance.

[bronze estuary]

wouldnt that get slow at some point

[wide ginkgo]

What do you mean with slow?

[bronze estuary]

and also how do I find the distance

like it would look buggy at some point

but also how do I find the distance between the center of the collider and the box

[wide ginkgo]

Nah, if you do the math corretly and perform all the movement etc in the same frame noone will notice.

You can get the center of the collider through Collider2D.bounds.center

[bronze estuary]

collider.offset?

oh

[wide ginkgo]

Then it's just a matter of comparing it to the position of the GameObject

[bronze estuary]

so I calculate the distance between the mid and that and I multiply it by 2 and move it that far forward or backward right?

so then int x = 2*(collider.bounds.center.x-transform.position.x);
??

[wide ginkgo]

It's a bit late for me to think math, but something like that yes 😄

[bronze estuary]

and then what do I do

like how do I know what to change or to add or subtract

[wide ginkgo]

Well depends on what the current flip and it's default orientation in the sprite. You can just check if(flipped) to determine whether you add or subtract.

[bronze estuary]

TYSM

it works amazingly

I didnt have to do much

big brain 🧠

[hasty steppe]

void onCollisionEnter2D(Collision2D other)
    {
        if(other.gameObject.tag =="enemy")
        {
            
            takeDamage(1);
        }
    }

this code isnt exectuing, yet i can hit walls and collide with the enemy

[wide ginkgo]

it's "csharp" for highlighting btw

[hasty steppe]

my b, first time

[wide ginkgo]

Np, you didn't put a capital O on onCollisionEnter2D that's probably your issue

[hasty steppe]

still does the same thing with capital

i figured it out, thank you

[wide ginkgo]

Btw use other.gameObject.CompareTag("enemy") instead of == "enemy".

It's a little bit faster, and it will warn you about spelling mistakes.

[hasty steppe]

setting up tags is just like adding layers rght

[wide ginkgo]

Not sure what you mean? But you can use whatever tag names you want.

[hasty steppe]

no worries, i got it, thank you

[bronze estuary]

kinda but theyre used for different things

[light perch]

How do I import a drawing into my Scene as a background again ?

Its a jpeg

[bronze estuary]

so how do I make an animation occur when I click left mouse button but if I press w then it should still finish the animation and then move

like how do I know when the animation ends

[lean estuary]

#archived-art-asset-showcase message

[bronze estuary]

can I like force an animation to complete and then make the chracter move

how do i know when an animation ends

[light perch]

Thanks, but I dont really understand that : D

[lean estuary]

@bronze estuary Best to ask in #🏃┃animation The channel also has tutorials pinned

[light perch]

nvm, i just dragged it there lol

[bronze estuary]

ok thx

[pure shard]

umm so my message got deleted

I need help with the jumping mechanics on a very simple game, im starting with unity

and i cant get my character to jump only when touching the fround, im trying to use void OnCollisionEnter2D(Collision2D other)

So that jump = Input.GetAxisRaw("Jump"); is only assigned when the character is touching the ground

[turbid heart]

was it a long code? if so, see #💻┃code-beginner pinned on how to post code here

[pure shard]

ill post a screen shot

[turbid heart]

no

use a paste site, it's easier to read and copy your code here if needed

[pure shard]

https://controlc.com/478b7542

that works?

[turbid heart]

yeah, so what's the problem? is it that onground doesnt change?

[pure shard]

no

its that jump = Input.GetAxisRaw("Jump"); assigns either way

no matter the onground value

[turbid heart]

well that's.. not possible. can you please try putting Debug.Log(onground); in your Update function? above everything else in it

[pure shard]

ill do that

[turbid heart]

you should put jump = Input.GetAxisRaw("Jump"); in {} anyway. it's better to avoid bugs

incase you add another line of code to your if statement

[pure shard]

yea i removed it to try soemthing

Debug.Log gives me True when on ground

and False when it leaves

but the character just flies up?

like gravity suddenly disappeared

[turbid heart]

hm? did that happen before?

[pure shard]

yes

But when i tried to put some prints to see what was going on it stopped happening

[turbid heart]

i dont have a clue, sorry

[pure shard]

i used another method and fixed it, dw

Now im having another problem that makes no sense at all, my character can jump and move left, but it wont move right

https://controlc.com/9afa229b

Its all exactly the same, why wont it work

oh wait

nvm lol

im dumb

[limpid drift]

hey does anybody know if there is a guide or someone that can explain me the right way to do database for player hp attack dmg and for the enemies and stuff?like how to store it and make it work with other scripts and such

[fringe cargo]

    {
        Enemy enemy = hitInfo.GetComponent<Enemy>();
        if (enemy != null)
        {
            Debug.Log("bru");
            Enemy.takeDamage(damage);
        }
    }```

i have this code but the last `Enemy.takeDamage(damage);` has an error

and this is that error

```Assets\Scripts\Firebolt.cs(20,13): error CS0120: An object reference is required for the non-static field, method, or property 'Enemy.takeDamage(int)'```

[robust ferry]

how to ray2d work??

[prime shuttle]

hey can anyone offer any advice on how i decelerate my player character? this is what i got so far:

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

public class PlayerController : MonoBehaviour
{
    private PlayerInputActions playerInput;
    private Rigidbody2D rb;
    [SerializeField] private float acceleration = 5;
    private float playerSpeed ;
    private Vector2 zeroV;


    // Start is called before the first frame update
    void Awake()
    {
        playerSpeed = 0;
        playerInput = new PlayerInputActions();
        rb = GetComponent<Rigidbody2D>();
    }
    
    private void OnEnable()
    {
        playerInput.Enable();
    }
    private void OnDisable()
    {
        playerInput.Disable();
    }
    // Update is called once per frame
    void FixedUpdate()
    {
        Vector2 moveInput = playerInput.MOvement.Move.ReadValue<Vector2>();
        zeroV = new Vector2(0f, 0f);
        if (playerSpeed < 10)
        {
            playerSpeed += acceleration;
        }
        if (moveInput == zeroV)
        {
            if (playerSpeed > 0)
            {
                playerSpeed = playerSpeed - acceleration;
            }
        }
        rb.velocity = moveInput * playerSpeed;

    }
}

[modest rivet]

Idk

[leaden sky]

maybe use force instead of directly setting the velocity. Then you can de-accerlate by setting the "drag"

[prime shuttle]

how do i apply force?

[leaden sky]

rb.AddForce(movementDirection * speed);

movementDirection is your player input

[prime shuttle]

tysm

[pure shard]

what is wrong with print and Csharp, i try to get some prints inside to check and it fucks up everything

[leaden sky]

? Debug.Log?

[pure shard]

oh

[last jasper]

My background still overlays everything in the game no matter what layer I put it on
Its inside of camera BTW

[misty vine]

Don't cross post. You'll also need to provide some more info - screenshots or something. No one can help if we can't see what you're doing!

[gloomy trout]

Hello

I got a error

When I drag my c# script to player

[misty vine]

You might want to show what the error is... no one here is psychic!

[gloomy trout]

Ok let me load it up

[last jasper]

Ok :D

[gloomy trout]

There

It loaded

Rip ded chat

@misty vine

[vocal condor]

It isn't a mono behaviour script?

[gloomy trout]

No

I'm following a totorial and this only happened to me

[vocal condor]

Does the script inherit MonoBahaviour?

[gloomy trout]

Idk

[vocal condor]

I cannot see, so I have to ask

[gloomy trout]

Wait

Yes

[vocal condor]

Are you certain?

The error says it doesn't.

[gloomy trout]

Yeah

[vocal condor]

Can we see?

For visual confirmation.

[gloomy trout]

Oh

[misty vine]

Your file name and class name have to match

[gloomy trout]

That's weird

[misty vine]

It's not, that's how C# works 😛

[gloomy trout]

Oh

Ok

It says the same thing

[misty vine]

I would suggest going and doing some beginner C# tutorials before jumping into Unity. You'll understand what you're doing so much more

[gloomy trout]

Ok

Thanks

[misty vine]

Also, this should probably be in #💻┃code-beginner which is also where tutorials are pinned

[gloomy trout]

Ok

[snow willow]

This particular requirement is actually a Unity one

[misty vine]

Oh! Fair enough!

[vital frost]

this is the last time I'm gonna ask this in a server im in, I know little to none about how camera scripts work, or how code works in general.
I want my camera to snap back to respawn after player death mainly because the camera needs to be on something in between death and respawn. and I wanna know what functions I would need to make that happen.
I'm sorry if me asking this again is repetitive, again I know little about this type of stuff.

heres the camera script below

[valid flax]

it looks like you could change the value of your Transform target variable when the player dies to a GameObject positioned at the respawn and the camera would move to that point. once the player respawns just change that value back to the player and it should begin to follow again

[tawdry relic]

is there a good tutorial on 2d grid-based pathfinding (e.g. for roguelike games)?

[vital frost]

how would I go about doing that?
if thats fine to ask.

[valid flax]

it's np at all

I can walk you through it but im not sure if thats best done here or in DMs. I'm completely new to this server and its rules

[vital frost]

it might be fine here, I've seen other long convos in this chat

[still tendon]

just do Vector3 spotOfDeathScreen = new Vector3(FILLINX, FILLINY, FILLINZ);?

[vital frost]

yeah, that doesn't work

[still tendon]

o ok

[valid flax]

create references in your script to the player and a GameObject placed at spawn by with
public GameObject player;
public GameObject respawnPoint;

then when you need to change the target you can use a line like
target= player.transform ;
or
target = respawnPoint.transform;

and the rest should take care of itself. it won't snap to position, but it will smoothly make its way to whatever point you tell it to that way

[vital frost]

would I put target = respawnPoint.transform; in its own update?

[valid flax]

and don't forget to drag the Player and Respawn GameObjects from your hierarchy in the inspector

not in an update but you would create a new function that can be called when the player dies or respawns

below your FixedUpdate method you would write something like

public void ChangeTarget(GameObject newTarget)
{
target = newtarget.transform;
}

[vital frost]

hm ok, ill work on it.

[valid flax]

it's hard to get anymore specific than that without knowing how you have your player and death detection set up, but however you are triggering the players death in the game you would then call that function in that script like this
CameraFollow.ChangeTarget(respawnPointGameObject);

[arctic parrot]

I need help with my code

[bronze estuary]

Does anybody know why I might get this error?

also I get this error?

but the code looks fine to me

OHHHH

im stoopid

ik why I get this error

[bronze estuary]

but this one still confuses me

[turbid heart]

i think that might be a Unity bug. Maybe try restarting your editor

[bronze estuary]

i already tried that

[turbid heart]

no clue, sorry. if it really bothers you, maybe ask in #💻┃unity-talk

[elder minnow]

that is because wallObject is null

You are probably calling breakWallSprite() before assigning anything to it

[turbid heart]

they are asking about this #🖼️┃2d-tools message

[elder minnow]

Oh I see, that confused me. My b

[late viper]

you can change the color of the sprite renderer but that tints the whole sprite. Otherwise you'll have to write a custom sprite shader

[worldly leaf]

what is this

[turbid heart]

You’re referencing something that’s null on that line

[worldly leaf]

@turbid heart

[turbid heart]

First of all, dont use GetComponent in Update. It’s heavy.
Second, please configure your visual studio properly. There’s a guide pinned in #💻┃code-beginner
Third, check that lr isnt null @worldly leaf

[worldly leaf]

@turbid heart ok i do it

but error is same

and the man in youtube video doing this in update

[kind stag]

Amazingly, people can make youtube videos of themselves doing inadvisable things. Look at it this way: that GetComponent call is going to look all through the gameObject for a LineRenderer, and is going to return the exact same object every time. Does it make sense to do a bunch of identical work every frame? Or could you perhaps do it once, and refer back to the result on every frame instead.

Also, if you put if(lr != null) { ... } around those three lines that start with lr., you will no longer get a NullReferenceException there. However, that means your gameobject doesn't have a LineRenderer component on it, so instead of getting an error, the code just won't run.

[boreal knoll]

Excuse me, I'm a Unity beginner
I am currently making a side-scrolling game, and I would like to ask about the confiner.
Since most of my objects change the animation by generating rays for detection,
if I use a collider to limit the camera, it will cause abnormalities in all my objects that need to detect the ground.
I would like to ask if there are any alternatives?

by the way, I'm a Chinese user, If any explanation is not clear, please let me know.

[marble badger]

I can do a jump with curve like this

I can also do a jump with curve like this

But how can i do a jump with curve like:
https://www.youtube.com/watch?v=BJXz5DF0SMY

In other words like this

[ruby karma]

looks like the first one, with less horizontal velocity and more vertical velocity

[marble badger]

that just makes it a wider jump

or is it hold on

i will try it out

but how can do a jump with the same curve as in the video using rigidbody that is

[ruby karma]

add more vertical force?

[marble badger]

using velocity

it doesn't give the same as the video

do you know how to do it

forget it

I will worry about this later

[kind stag]

I like to use Wolfram Alpha to test out equations for curves and stuff.

That was one where I wanted it to hit specific values at specific points

That was just to curve off the end of a cylinder

this one looks something like you want. Use time as the x value (remapped from 0 to 1) and multiply y by whatever the jump height should be

although of course that would be controlling height when you'd probably rather use gravity

[nova frigate]

I'm kinda new to using unity, and am making my first proper game. I would like to know how I could trigger and event (gameover) when the player enters a y level less than -10.
I'd really like to know so that I can continue making my game!

[rocky temple]

if(transform.position.y < -10)

[turbid heart]

do you have a method that sets your game to GameOver yet?

[nova frigate]

Yeah

Thank you

[nova frigate]

OMG it actually works! Tysm!!

[wet night]

Why am I getting this error

With this code ```using UnityEngine;

public class Character2DController : MonoBehaviour
{
public float MovementSpeed = 1;
private void start()
{

}
private void Update()
{
    var movement = Input.GetAxis("Horizontal");
    transform.postion += new vector3(movement, 0, 0) * Time.deltatime * MovementSpeed;
}

}

[late viper]

you're looking at the wrong script, the error tells you which script its in

[wet night]

Ok I fixed that error but this then came up with this script

Both were the same name by mistake

[late viper]

code is case sensitive, check your capitlization

[wet night]

What parts of need to be fixed? I followed a tutorial

[late viper]

the errors basically tell you

next to the script name is the (line number, character number)

so follow that to see where the errors are

then reference the tutorial code

[misty vine]

Check your spelling too

[chrome lintel]

Dumb question is there a way to freeze directional velocity instead of writing to it every frame

like i want something to keep going in a direction on the x axis

but still want y axis gravity to apply

[cursive spruce]

hello so im trying to make a 2d survival game and im trying to make ore generation but i dont know how i looked on youtube but its moslty 3d or minecraft vids

[arctic parrot]

why am i getting this error

with this code

[late viper]

you have multiple Update()s

[arctic parrot]

I am beginner so what should i do

[late viper]

merge them together

[snow willow]

Just take all the code inside the { }s and put them into one

[late viper]

^

[snow willow]

It's possible you have more errors after you do that

They may be completely unrelated

[late viper]

also don't copy code without understanding it

[arctic parrot]

yea i did get more erros when i tried to take the void update to the private void update

[snow willow]

What errors

Either you merged them incorrectly, or you just have other unrelated errors

To merge then you should take this:

void Update()
{
    // A
    // B
}

void Update()
{
    // C
}```
And turn it into this:
```cs
void Update()
{
    // A
    // B
    // C
}```

If you've done that, and you still have errors, then they are about something else

[snow willow]

Go to each of those line numbers mentioned and see if you understand what's wrong. If you don't... I suggest not copying code that you don't understand in the future. Perhaps start over with a tutorial, and try to understand every line of code before continuing

[late viper]

oh jeez... I suggest you start with some basic unity tutorials before jumping into this

[arctic parrot]

yea i fixed its fine now thanks

[autumn marsh]

Why is it giving me NullReference Exception if I already declared HealthBar as a public variable and it already shows in the inspector?

the code works, but it still gives me the error

[wide ginkgo]

You are changing the variable in start. If you set it in the inspector you shouldn't change it as it's already referencing the correct object

[autumn marsh]

OHhhh I got it

tysm

:D

[vapid gale]

smh my head

[uneven bolt]

hi every one I'm new to unity and an looking forward to program games or even publish one

translation help i have a smooth brain and can't remember a line of code for more than two seconds

[elder minnow]

Forgetting the syntax of particular stuff is normal, the key is to learn how to read documentation for that fresh reminder

[turbid heart]

stop using it as an excuse and learn. probably better to say "thank you" or "sorry i dont understand what you mean by this part, instead of "i cant do it lol, i'm dumb". That's how you solve it

[uneven bolt]

thanks

[turbid heart]

that being said, dont be discouraged to ask, but I'd advise you to try to solve things first on your own. Even if you can't solve it, explain the approaches or attempts you've tried. People are more willing to help those who help themselves first.

TLDR: Try

[uneven bolt]

look the reason i got unity is so i can solve a problem the problem being that there are no good mobile space sandbox games so im going to make one

[turbid heart]

hm, sandbox game. I've never made one before, so I don't know how difficult or complicated that might be, but all the best. keep in mind that's probably not usually someone's first game, so it will be tough

but if you're clear on what you want to achieve, that'll make it a bit easier. all the best.

[uneven bolt]

I love space and i love sand box simulators and theres no games that have both so im going to make one

my only problem with learning is it doesn't really stick unless i can actively talk to some one after learning some thing

[uneven bolt]

can we try to make one?

[turbid heart]

the goal is not memorising. It is understanding. and do it enough times, and the understanding will sink in

[uneven bolt]

i know bu fore me its a little dificult

[turbid heart]

sorry, i'm not interested. if you want to find people,
#💻┃unity-talk message

you're making it more difficult for yourself by saying it's more difficult for you

[uneven bolt]

oh ok thx

[turbid heart]

either way, this isn't a encouragement channel, so i'll keep it to a minimum now. I do suggest you start with some basic tutorials though.
http://learn.unity.com/

[uneven bolt]

i mean it is difucult i mean i can learn and remember over 60 diferent words but whate a miunet

how the f did i not think of doing that

eh brain.exe stopped responding a long time ago

[cursive spruce]

so i need help i wrote a script that make a day and night cycle but its not working

let me get the code

what was that

i got pinged

[uneven bolt]

w-

what

[cursive spruce]

nevermind

anyway i need help

[uneven bolt]

why did it deleate my message tear was nothin ofencive about it

[turbid heart]

check your spelling. You need to set up your Visual Studio properly, and it'll auto suggest the properties that Light2D does have

[turbid heart]

was it a long code?

[uneven bolt]

no i was say in that his name was adorible

[cursive spruce]

ahh thanks

quck quack

[uneven bolt]

your welcom

[turbid heart]

for example, I'm guessing there isn't one called "intesity", but perhaps "intensity". I can't find the docs on Light2D

[turbid heart]

first things first though, please set up your visual studio
https://docs.microsoft.com/en-us/visualstudio/gamedev/unity/get-started/getting-started-with-visual-studio-tools-for-unity#configure-unity-to-use-visual-studio

[uneven bolt]

the only way this moment couled be cuter is if you actualy had a duck

[cursive spruce]

ok

[uneven bolt]

do you...?

[cursive spruce]

huh

[uneven bolt]

jk i wish

i had

done that

[cursive spruce]

ok

also do i have to reinstall visual studio to get unity support

[turbid heart]

No. Just follow the steps in the link. Scroll all the way up and start there if you have to

[uneven bolt]

can some one tell me why you tube only gives me tutorials on how programe stuf in stead of telling me wtf it does

like why youtube why

[cursive spruce]

ok

[uneven bolt]

confused.mp4

[turbid heart]

Because that’s what gets views. Everyone wants the fun part of just following something and getting the game done. Not necessarily understanding it. Why do you think i sent you the unity learn link?

[uneven bolt]

ohhhhh thats what that was welp see brain is sooth af

[turbid heart]

You’re supposed to research on your own how things work

Read the docs

[uneven bolt]

got it

brain.exe is responding for the first time in 6 years

ok I have a visual studio set up

i have unity

i also have a crapy laptop sts can only end well

[cursive spruce]

btw wheres the button modify

[uneven bolt]

hey if i wanted to simulate gravity can I just apply a atraction force and be fine or do I need to do some thing to stop the pulling force after a bit if I ad more thane one gravity spot

[turbid heart]

is this 2d or 3d?

[uneven bolt]

2D

[turbid heart]

okay. I dont know.

[uneven bolt]

so like three cyercles and all of them are pulling on the ship you've built will i pull you to one of them or will it pull you to all of them and mess every thing up

brb

[cursive spruce]

btw wheres the button modify

[abstract olive]

Modify what?

[cursive spruce]

i need to put my visule studio support unity

[abstract olive]

Not sure how anyone was supposed to guess that from "button modify". Still not even sure what you're asking though.

If you mean, you want to configure your visual studio to work with Unity, there's instructions pinned in the #beginner-code channel.

[cursive spruce]

oh ok

[unreal dome]

when do you just need a collider and when do you just need a rigidbody?
like are there known bugs to having a collider but not rigidbody on that collider?

[turbid heart]

colliders are bounding boxes, rigidbody lets an object have physics. There are some cases where you need a rigidbody in a collision. See OnTriggerEnter's documentation

[unreal dome]

thanks!

[iron notch]

why does my object keep teleporting through my scene?

        _direction = (new Vector3(_positionX / 100, _positionY / 100) - _plank.position).normalized;
        Debug.Log(_direction);
        _rigidbody2D.velocity = _direction * _moveSpeed;

new Vector3(_positionX / 100, _positionY / 100) is the position we want to go to`
_plank.positionis the current position where we are
_direction is the difference from the current position and the position we want to go to
_rigidbody2D.velocity = _direction * _moveSpeed; sets the movement direction and applies a speed factor to the rigidbody

i am using this to cap the speed

        //hardcap the max speed
        if (_rigidbody2D.velocity.magnitude > _maxSpeed)
        {
            _rigidbody2D.velocity = _rigidbody2D.velocity.normalized * _maxSpeed;
        }```

if i use ``_plank.position = new Vector3(_positionX / 100, _positionY / 100);`` it is at the correct position (but then physics wont work correctly that is why i cant use it)

using ``_mainCamera.ScreenToWorldPoint(Input.mousePosition)`` as the target position works

[latent basalt]

How do I generate 2d shapes during runtime using scripting?

Without having to load them externally?

[iron notch]

i believe that you could generate svg files through code and display them

[latent basalt]

I did think of that but didn't know it was possible

Is there any package I need to install to do so?

[iron notch]

For SVG, yeah but I do not know if unity allows for them to be generated

[latent basalt]

Hmmm can't find anything

[icy turtle]

Hi, does the UI Update, Awake etc only runs in the main thread?

[modest marsh]

yes

[icy turtle]

@modest marsh Thanks!

I have a question I am trying to optimize the resources as best as possible in unity (GPU, CPU calls).

I have a 2D game that does not use physics, but if it is in motion either because it uses the translation of the objects or they have an animation based on a spritesheet at all times.

My question was whether the best thing would be to continue using sprite rendered or to use a canvas for the whole scene?

Sometimes my game in unity create a webview to load games made in "HTML5 Canvas" which may affects performance.

[modest marsh]

if you're manipulating elements continuously, keep with the sprite renderer. You might trigger a lot of mesh rebuilding otherwise

a few minutes of https://youtu.be/_wxitgdx-UI?list=PLX2vGYjWbI0Rzo8D-vUCFVb_hHGxXWd9j&t=1424 this presentation provides some more details about why it would be a bad idea to use a canvas in your use case

[icy turtle]

i have seen this conference before, i was asking to check if anyone have a different opinion just to make sure.

Thank you for your reply @modest marsh!

[modest marsh]

you should have quite good performance so long as you're making sure your sprites are being batched properly, so make sure you're using sprite atlases whenever possible

[wet night]

I am all of a sudden getting these errors why?

[turbid heart]

there's no such thing as Physics2DObject

[wet night]

But how I made this game and it worked perfectly

[turbid heart]

well, now it's clearly not

I cant find a Physics2DObject class in Unity, so is that something you wrote?

[wet night]

Yes

[turbid heart]

show it

show where you wrote that Physics2DObject class

[wet night]

I put it back in and I just got 999+ errors

Oh wait I am retarded I removed the scripts. I needed to add them back in

Ok last queston WHY am I getting this

[turbid heart]

read it. that's plain english

[wet night]

I dont know what to change the settings are already set

[turbid heart]

Input button Submit is not set up

your Submit input is not set up, i think @wet night

[wet night]

I just want to ask what did I need to do to make my characters stand straight up

[turbid heart]

are they falling over due to physics? there's a constraints setting in your rigidbody

[wet night]

I think so yes. This is the rigidbody settings

[turbid heart]

lock the rotation in the constraints

[wet night]

AWESOME. This is the last thing. Is this code correct ```using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{

public float speed = 5f;
private float movement = 0f;
private Rigidbody2D rigidBody;


// Start is called before the first frame update
void Start()
{

    rigidBody = GetComponent<Rigidbody2D>();

}

// Update is called once per frame
void Update()
{
    movement = Input.GetAxis("Horizontal");
    if (movement > 0f)
    {
        rigidBody.velocity = new Vector2(movement * speed, rigidBody.velocity.y);
    }
    else if (movement < 0f)
    {
        rigidBody.velocity = new Vector2(movement * speed, rigidBody.velocity.y);
    }
    else
    {
        rigidBody.velocity = new Vector2(0, rigidBody.velocity.y);
    }

}

}``` Due to my character not moving just standing there

[turbid heart]

your character is not moving? are you saying your movement is not working?

[wet night]

Yeah. I press a key and it doesnt do anything

[turbid heart]

are you pressing the correct key? honestly I dont use Input.GetAxis, so I dont know what the default is

if you Debug.Log your movement after Input.GetAxis, does it print anything other than 0?

[wet night]

To be honest I believe I am pressing the right key and I got the code from a tutorial due to I dont know how to code in C#

[turbid heart]

just Debug log to test

[wet night]

Is that a separate code or do I add it in

[unkempt gulch]

is there any way to make an object follow another object

i need my healthbar to follow my enemy plane

[still tendon]

im in unity 2d how do i setup killing enemys with a bullet that is shot

[tall current]

look up Interfaces - I believe they'll be useful.

[subtle vessel]

I recommend creating a Health script that everything in your game that can take damage has. Bullets should have a Bullet script that you attach to the bullet object. The bullet object should have a collider2D attached to it with the isTrigger checkbox marked active, making it a trigger collider.

Then, in the Bullet script, write a function called OnTriggerEnter2D which will get called the first frame that the bullet's trigger collider intersects with another collider.

In OnTriggerEnter2D, check whether the object you've collided with has a Health component (using GetComponent<Health>()). If it does, deal damage to the health component and destroy the bullet object.

In the health component, every time it receives damage it should check whether its health has been reduced to 0, and if it has it should either destroy the gameobject it is attached to, or trigger a death animation, or w/e you decide the object should do when it dies.

[eternal wyvern]

I have a question, and I imagine it'll be pretty hard to explain over text, but essentially I have a player character that moves through physics, specifically by swinging a stick at the ground which launches him forward

However, using a pretty basic player movement script to get him to jump and walk causes the physics to act wonky, now he only goes straight up once he hits the ground with the stick

I'm not sure what in my movement script could cause this, but things do work as intended when it's off

[snow willow]

Most likely you're doing something that isn't "physics friendly" in your script

but hard to say without seeing it

[eternal wyvern]

oops, hm whats the best way to share the script here?

[snow willow]

#💻┃code-beginner message

[eternal wyvern]

thanks!

https://paste.ofcode.org/spmTvYAnWtAhSz8WkZHf7k

So I narrowed it down to whatever is happening in FixedUpdate, but I don't know why it'd behave ;like this if I'm not moving with A and D to begin with

[snow willow]

ok so what's happening that you're not expecting to happen?

I will say that this looks pretty unusual: rb.AddForce(new Vector2(rb.velocity.x, jump));

adding force based on your existing x velocity?

that means you'll be pushed harder to the right based on how fast you are currently travelling to the right for example

But anyway - rb.velocity = new Vector2(move * speed, rb.velocity.y); this will overwrite any existing velocity you have in the x direction

and if the horizontal axis is currently 0, it will set it to 0

[eternal wyvern]

oh that makes a lot more sense, so if I place it in an if limiting it until I actually press A or D that should fix it?

[snow willow]

Try it out

I'm not 100% sure what you're going for

[eternal wyvern]

Lol ya it's a pretty unusual mechanic so it's hard to explain, but it worked out, thank you for your help!!

[cursive spruce]

can someone help me plz

let me get the code

You heard me

[cursive spruce]

they are the same tho

ok so i fixed it but its not giving me caves

[obtuse sierra]

how can i get access to an images sprite

can't do getcomponent<image>().sprite

[snow willow]

That's because it's Image

not image

[obtuse sierra]

yeah sorry didnt type case sensitive, anyways Image capital I didnt work

[snow willow]

also you need using UnityEngine.UI; at the top of the file

[obtuse sierra]

thats probably what im missing

works now

thanks

[snow willow]

That's what the error is saying when it says "Are you missing a using directive?"

you can only assign to an array element, you cannot add to it

If you want to be able to add use a List

[eternal wyvern]

I have a very general question, but essentially for a game mechanic of mine to work I had to use a whole bunch of Serialized Fields and expose various things in the editor, All of these things though are found under one parent game object which is my player prefab

I heard that getcomponent<> and GameObject.find, have a slight performance hit so I figured exposing in the editor is the best solution, should I be looking at another way of sharing data between these gameobjects?

[turbid heart]

you can assign in the inspector. GetComponent is also okay if you're caching its result where possible

[eternal wyvern]

Alright great, yes I just assigned in the inspector, I figured that even though it was a lot of items, the whole thing is a neat prefab in the end and all the logic works so shouldn't be too bad

[still tendon]

Thanks, I think I did something similar @late viper

[vale atlas]

If you can directly do the reference its always better. Doing get component in awake, onenable has some performance hits if its done a lot of times during a scene awake or prefab instantiation

[royal cliff]

Hello, my first game making experience was with a little game engine named love2d. I decided to switch to unity for a small game i am working on. I can't for the love of god figure out a good top view char controller, with friction based on what surface it sits on. I tried physics materials and it does not work because my object cannot sit on another rigid body with a box colider. Can someone please help me or give me any idea?

[snow willow]

One option is to use the 3D physics engine with a top down view and use friction normally

You can still use 2D art with the 3D physics system

[royal cliff]

Thank you! I will try that.

[late viper]

http://help.vertx.xyz/?page=Programming/Physics Messages

[snow willow]

You are moving your bullet by directly modifying the transform position. This bypasses the physics engine entirely

you must move the bullet with Rigidbody2D methods

Simply setting the velocity of the bullet's RB2D when it spawns should be sufficient to do all the motion if it's just moving in a straight line at a constant speed.

[signal tundra]

omg thank you

Does anyone know how I could turn on Snapping for spriteshapes (or any 2D path) by default?
Currently you have to turn on snapping every time you select an object that uses a 2D path.
Perhaps there is a way to customize the editor? or through reflection?

Lootdrop object

Level 1 object

Keep getting error like this:

[still tendon]

The 4th element isn't assigned

Yes, I want the loottable to determine that.

It should be replaced by firstlootablemarble for either board or level scripts.

But it doesn't fill it up.

@still tendon

Code?

It's hard to solve the issue without the code

For board or which script?

[the level and lootdrop scripts are a few msgs up]

@still tendon

Yes

board.setup monsieur.

https://hatebin.com/prfjwnrzgr

@still tendon

Maybe it's a scriptable object vs script issue?

Like instead of lootdropsystem communicating with level script, it should communicate with lvl 1 scriptable object?

It appears my lootdrop script needs to be attached to my level 1 game object. I'm not 100% sure what to do from there.

I think if I have my lootdrop script push the gameobject onto the right scriptableobject (level 1), I think it'll start clicking.

Trying to play with that for now. Not clear on how to do it.

I suppose, the question now is how to change a component in a scriptable object using another script.

[arctic parrot]

Im having a problem where when i start my game i have to jump to move and sometimes i cant move time to time i also have problem with my wall sliding animation

For some reason it still says the level isn't updating marbles.

Any ideas?

For some reason, even during run time, the dots don't include the lootdrop marbles into their dots gameobject.

[wide lagoon]

I think your code should be crashing with an ArrayOutOfBounds exception

You are accessing Array[Array.Length] which is out of bounds

on line 64

It should be board.dots[board.dots.Length-1]

Same goes for the line above it

Arrays start at 0, so an array of size 1 contains 1 element at array[0], but array[array.Length] (length == 1) is out of bounds

Im also a bit confused what the bracket on line 47 belongs to

Same for line 41

[still tendon]

KK, lemme see, thanks @wide lagoon

Also, excellent choice in PFP.

[still tendon]

Alright, zeroed in a bit more.

OK, so my board can track it's on level 2.

Loot drop not so much.

I'm using this line in particular to find the level # in integer form.

So that works.

But my lootdrop uses the same method and doesn't work for some reason.

I think if I figure that out, I might be set.

Anyways, I had fun breaking my game so far today. Look forward to more of it tomorrow. Thanks for help so far.

[unreal mural]

does anyone have a good article/reference on collision resolving? Feel like I'm struggling with this and looking for a good example

[solar thicket]

can you be more specific? like how the physics works under the hood?

[unreal mural]

Not the physics aspect of it but coding the architecture for responding to the collision events and how they can cleanly resolve across the entities in the game.

[solar thicket]

well the answer, as with everything is probably 'it depends what you're trying to do'

[unreal mural]

Using the OnTriggerEnter/Exit hooks in a naive way leads to sideeffects when events get more complex. So using a 2d Platformer as the example, where the player and enemies may respond in their own ways.

I've tried using both sub/pub and bubbling up events in a method chains. But they both feel limiting

[solar thicket]

yeah, i'm not a fan of the hooks either but i don't have a ton of experience actually building something robust around unity physics

i would probably do a lot of spherecasts and stuff instead

so that you have full control over the execution order and handle all that stuff however you see fit, rather than relying on unity

you could also buffer everything, so use the hooks but don't do any logic in reaction to them

instead, resolve them to a set of collision events on a timeline and then parse and handle that for your game logic

[unreal mural]

That sounds like the best solution

Buffer the list of conditions, sweep them all, add the successful conditions to a list and execute them in a second pass. I suppose priority could be given and the list could be resorted

but then thinking about how to avoid garbage collection... hearing battlefield noises

[solar thicket]

sounds like a problem for future you 😄

[unreal mural]

Best to just procrastinate until I regret it like always

[solar thicket]

set size buffer and reuse the event objects and maybe you'll be ok? definitely not my area though

[last jasper]

anyone able to help me because nobody responded in beginner code and i don't want to say it again because thats awkward

[unreal mural]

post your code?

[solar thicket]

you've shared nothing about your problem, how can anyone help you?

[misty vine]

But posting in another channel asking people to go look for your question in a different channel isn't awkward?? 😛

I would suggest reading the information in #854851968446365696 and learn how to ask a question so that people can answer it. "It doesn't work" isn't useful, and people just don't want to do the whole "what doesn't work" "post your code" etc.
If you want help, provide all the information, don't make people go fishing for it!

[pure shard]

um hi! ive started using lights, and ive added a Point Light 2D, the problem is, when selecting target sorting layers for that light, i only get 3 options, 1. None 2. All 3. Default. why?

[knotty barn]

@dire sorrel Not a code question. Ask in #💻┃unity-talk

[north forge]

Hello everybody. Not sure which channel to choose for the question.
I want to create a canvas with an image that changes via scripts.
There's a lot of images placed inside 3-4 levels of folders and I need to load them one by one withe their full path
like load /Assets/Images/0/01/015/aaa.png
Is this possible? For some reason can't find a good code example

[solar thicket]

https://docs.unity3d.com/530/Documentation/ScriptReference/Texture2D.LoadImage.html

[north forge]

Thanks, will go reading right away

[north forge]

nah,this isn't helping. i mean, i still don't get it
I have a canvas with component mesh renderer

        byte[] fileContents = File.ReadAllBytes($"Assets/{filename}.PNG");
        Texture2D tex = new Texture2D(width, height);
        tex.LoadImage(fileContents);
        Canvas img = GameObject.Find("test").GetComponent<Canvas>();
        img.GetComponent<Renderer>().material.mainTexture = tex;

With this setup I can see how test component Default-Material (Instance) (Material) changes in runtime
but i've no idea how to actually apply it to the canvas renderer

[late viper]

why are you trying to apply it to the canvas instead of an element on the canvas?

[north forge]

I can't find a single good example of how to display a simple picture, that's the problem
There's an Image component on the canvas too. is this enough to make it display something?

[late viper]

yes, thats what you're supposed to be using, not the canvas itself

you should watch this https://learn.unity.com/tutorial/ui-components

[potent iris]

Hello friends, can someone tell me how to move a 2d object in the direction its facing?

[subtle vessel]

transform.up gives you a vector pointing along the y-direction of the objects transform. transform.right gives you a vector along it's x-direction

[potent iris]

yeah thanks

is it possible to apply like an impulse without having a rigidbody or moving the rigidbody in the facing direction?

[north forge]

ok, so I tried both, canvas image component and image object as a canvas child. I can see default material changing in runtime, but honestly i've no idea how am i supposed to choose options on image to make it all visible.

[late viper]

you're supposed to be putting it in the Source Image field

not using a material

you should really watch the UI tutorial I posted

[north forge]

But how? It only allows putting assets there. I want to put a file by its full filename.
I saw that video and didn't get anything new

ok, i'll see it once more

[late viper]

oh ok I get what you want now

you still need to use LoadImage like Prakkus told you, but you need to put the loaded image in the Source Image field in the Image component

you can also use the Raw Image component instead so you don't have to convert it to a sprite

[north forge]

RawImage seems to do a better job here.
I literally came to the point when I stopped understanding anything.
I load, run and see movies displayed on a canvas, create and destroy text messages with no problems, but for some reason, displaying images is beyond my comprehension.

after a million of check/unchec, add/remove enable/disable components and properties, somehow got it working... more or less.
At least I can see something changing on the screen 😄
Thanks

[glacial bay]

hey my UI stuff doesn’t show on my game scene but shows on my phone simulator scene, how do i fix this?

[subtle vessel]

do you have the ui layer hidden?

[glacial bay]

yea that was the problem LMAO i just fixed it

[still tendon]

OK, is there a way to take a gameobject from somewhere else and store it into an array?

Like if I generate the name of the gameobject in one script and try to add it to an array of a gameobject?

[north forge]

is GameObject.Find() what you seek?

[still tendon]

Maybe. I'll get back to you if it works.

[still tendon]

Well, I tried to use gamobject.find but couldn't get it to work.

But I am making headway off your suggestion. I can't set the marble, but it's at least blank instead of being solely set on lvls. Thanks @north forge

OK, I can set the marble.

With any luck, next week I'll have this loottable stuff up.

Thanks @north forge

[mellow sleet]

hey im new to unity and c# aswell and i want to rotate a object by 90° can someone help me and tell me how?

[snow willow]

https://docs.unity3d.com/ScriptReference/Transform.Rotate.html

[mellow sleet]

no they're spawning but when they spawn they're laying down on the ground so its moving forward (for the object its moving down (what it should do) ) so i need a code that rotate these while spawning

[snow willow]

Fix your 3D model in blender

https://www.immersivelimit.com/tutorials/blender-to-unity-export-correct-scale-rotation

or whatever 3D modelling software you made your model in

[still tendon]

I'm also unsure of where to ask this, but I've got a triangle shaped 2d collider on a triangle shaped sprite, and a ball with a rigidbody2D and a circular 2d collider and yet sometimes the ball seems to just phase through bits of the triangle instead of colliding. how fix? This is my first time trying to make something with Unity btw.

tried increasing the collider bounds on the triangle but the ball still clips through the triangle occasionally, usually around the points

[modest abyss]

So I have this problem, I want the player to be able to move the laser along the constrained arc by pressing and dragging the laser, What is the approach to follow here?

[subtle vessel]

If the arc part of a circle? If so, just use trig functions to position it.
x = radius * sin(angle)
y = radius * cos(angle)

[subtle vessel]

Try changing the collision detection and interpolation settings on the rigidbody. Continuous collision detection especially should help

[modest abyss]

okay thankss alot

[toxic anvil]

can anyone pls tell me why my player is invisible though it shows the player in scene mode when z is in negative but then if i play it will again become inivisble

this happens only when i add my background

and when i redo the background thing it will work fine but if i restart the project it will give the same problem

[turbid heart]

probably because you set their z to 0 when you press play?

[toxic anvil]

yes

it comes to middle automaticly

even when i set it somewhere else

[turbid heart]

you should look into sorting layer

to make sure it's always on top

[toxic anvil]

the sorting layer is in normal

what should i do then? am kinda new in this

oh nvm it worked

i changed the order in layer from 0 to 1 and now i can see the player

thanks for helping

[still tendon]

hello

anyone here

my enemy patrol script is not

working

need help 😭

[gusty ermine]

I need help. I need to do the following, and I don't know how to do it. Camera cannot zoom, or pan outside the canvas. However, the images are the ones zooming not just the camera. So.... let me explain.
I would like the UI to always be visible
While the board zooms/moves
So ideally the areas wherever the board ISN'T do not move/zoom/pan
https://gyazo.com/031c662fe22e831801d6e7b50a218ac4
So I think we need to make a board moving and resizing system probably using masks, so the UI is visible while the map changes sizes and/or moves
The left side will eventually contain an expanded board, but for now it'll just be a random graphic, the right will contain important buttons and information, and the top will contain game buttons (menu, level select, options, quit etc...)

How would I go about this?

[vocal condor]

You would probably want to ask this in #archived-game-design since this isn't an implementation question but a design question.

[vital frost]

hey I'm having this issue where it wont let me use "void update" for this action
Is there another type of update that would suit this?

[snow willow]

I'm going to just guess that you have more than one Update method

you can only have one per script

but, really, you should be reading the error message to figure out what's wrong

[vital frost]

yeah I know that.
so I just find a update method I haven't used or come up with a script that would just be for this system?

[snow willow]

I don't really understand what you're saying

[vital frost]

I figured it out
Its all good now

[patent flower]

I have a Scene (settings menu), a nother Scene(Game with Pause Menu) and a nother Scene(Start Menu). Both Start Menu and the Pause menu have a button in the Settings menu. Now i wand a button in the settings menu, which takes me back to the menu i had before. how do i do that?

[limpid drift]

for one i just do this ```csharp
spriteRenderer.flipX = rb2d.velocity.x < 0;

for question 2 i suggest you just look up a guide on it to understand how the animator works

[bronze anvil]

By using tilemap shadow caster, is it possible to get simple rough shadows like this?

https://cdn.discordapp.com/attachments/730787368004747304/856182654319722536/unknown.png

If a tile is 2 tiles high, the generated shadow would be cast over exactly two tiles in front.

[candid flame]

can someone help me urgently?

[abstract olive]

No crossposting @candid flame.

[candid flame]

oh, sorry about that

[pseudo wave]

Hello, is creating an enum with Player states like walk, attack etc good practice or bad practice and will give me many errors in the future?

[snow willow]

creating enums is not in and of itself good or bad

what are you doing with the enum>?

[pseudo wave]

in my top down game like zelda i have my character permanently on walk state and then i keep changing it for attacking, interacting, when he recieves a hit (to add knockback) etc

just wondering if im doing it in a bad practice manner or if this is completely fine

[snow willow]

I mean it sounds like you are describing a state machine

which is a completely normal and fine thing to use

[pseudo wave]

ok thanks!

[lament canyon]

Hi, how do I make a top down camera that follows the player, but when it gets close to the edge of the map it stops following the player until the player walks away from the edge of the map. like for example in the game Hades where the camera does this.

[fallen siren]

you can constraint your camera position to the player, and add a check if the player is at a specific distance from the border, the camera adjust the constraint accordingly

[lament canyon]

How do I check if the player is close to the border?

[subtle vessel]

Check out cinemachine. The camera confiner component does exactly what you want

[lament canyon]

thx, ill check it out

[hazy dirge]

What do you guys suggest is the best way for handling Metroid-style guns? Currently I have my player class, which is where input is handled as well as movement, then I have my weapon class which is on a game object as a child to the player object, that way it moves with the player, and then I have a projectile prefab which instantiates on player fire via the weapon script. The projectile itself has a rigid body and a collider and destroys upon being collided with.

It works well, but my issue is that 1: using rb.transform.right * speed only ever lets the bullet travel positively on the axis. I account for facing direction in the player class, so if I could pull that from the parent object within each instantiated bullet, it would work, just not sure how to do that. And 2, when the bullet collides with another rigid body, the force from the bullet is transposed onto the contacted object, so it causes the target to move backwards. Is there a way to have that force not transpose onto the other object?

Also, is this a good way of doing this at all?

[modest cargo]

Our player's jump height reduces if the player is selected in scene view during play mode
I thought this wouldn't matter but the jump height seems similarly reduced in build
Have to check again for missing deltatime stuff, but what else could possibly cause something like that?

[craggy kite]

If you rely on framerate and do not code independent from that, it might vary in your visual outcome. Also having stuff like scriptable objects to feed your variables which get reset in the build might cause something like this, depends on how your code looks like and the whole project setup maybe too

[toxic anvil]

why is my text hidden when in the background?

anyone?

[hazy dirge]

Drop a screenshot of your canvas’ components

[toxic anvil]

these?

[hazy dirge]

Yeah, them

[hazy dirge]

Does your text have graphics raycasting enabled?

[toxic anvil]

i dont see graphics raycasting in text but raycast target is enabled

[hazy dirge]

Under canvas’s render mode, try changing between the options

[toxic anvil]

theres only one option

[hazy dirge]

There should be a world space option

[toxic anvil]

i tried

its still the same

also graphics raycasting is in canvas

[hazy dirge]

Right, it should be there.

[toxic anvil]

so what should i do in graphics raycasting thing?

[hazy dirge]

https://stackoverflow.com/questions/62152057/unity-ui-text-not-displayed

[toxic anvil]

bcs changing the options in render mode didnt wrok

[hazy dirge]

If it’s enabled then nothing

[toxic anvil]

its enabled

[hazy dirge]

It might be an anchoring issue, though. That little box with the 2 squares and a red dot on your text components, click it, then change the anchoring to top left

[toxic anvil]

i already did

[hazy dirge]

Ok, try moving your main camera towards and away from the text on the z axis to see if it shows up

[toxic anvil]

yes in game it shows but all my bgs and characters are gone now

and in scene its still hidden

[hazy dirge]

Yeah, so your text is not in front of everything else

So despite the visual being 2D, you’re still working in a 3D environment, so you’ll need to situate things to where UI stuff shows up above game stuff

[toxic anvil]

yes

how do i change it 2d enviorment am so confused at this part now ;-;

[hazy dirge]

You can just change the value of the z axis for game objects within their transform

Put your camera at like, -10z, your canvas (ui) at -1z, and game stuff at 0+z

Depending on your camera’s facing you may need to invert that

[toxic anvil]

0+z?

[hazy dirge]

0, 1, 2, 3...

[toxic anvil]

i see

uh so canvas is not letting me change z :/

is it bcs i have set it to camera?

[hazy dirge]

Yeah, it’s using screen space

[toxic anvil]

at -10 the objects shows up but at - 1 text doesnt

[hazy dirge]

Which should work. Not sure why it isn’t

Set it back to screen space then

[toxic anvil]

ok

it is screen space camera

oh

canavs z is 990

90

i mean

[hazy dirge]

Yeah, so change it to world, put it at -1, then change it back to screen

[toxic anvil]

it came back to 90 again

hold up

i changed it to world space

and 1

now it shows up the text -

[hazy dirge]

Yeah, for world space it should

[toxic anvil]

i changed it to camera bcs it wasnt showing me text since it was literally very big then the camera itself

[hazy dirge]

It’s working now though?

[toxic anvil]

yes

[hazy dirge]

Sweet

[toxic anvil]

thank you for helping

[hazy dirge]

Np!

[sharp herald]

Is it possible to access the data of a tilemap?

Like to do collisions and stuff

At the moment I'm just dragging in solid tagged objects wherever my tiles are but I'd like to handle this in a smarter way in future

[modest cargo]

I don't know about accessing data but you can use the Tilemap Collider component

Usually I have one tilemap with the collider and all solid tiles, and another without for background or foreground tiles

[sharp herald]

oh this sounds awesome. thanks for the heads up, I'll give this a go now

[tepid wolf]

anyone any good tips on how to make an enemy that follows you if you are in range

[tender condor]

yea

actually use Magnitude to check if player in range

or collision sphere

[tepid wolf]

oke

[onyx night]

Hi guys. I'm trying to get top down shooting working in 2D, and I am using Brackey's "TOP DOWN SHOOTING in Unity" as a basis.

But in that video, they use a character sprite that rotates, and based on the rotation, it shoots in that direction because the FirePoint is attached to the rotating model.

I don't want my character to rotate, I have it set up with 4 different "animations" for each direction and my character faces the last direction inputted, and I want them to be able to shoot in any direction (at least for now, later I'd like to have them face the direction they're shooting if they're not moving). So to let my character shoot where my cursor is, but without rotating the model itself, I created a rectangle under the character that rotates with the firepoint on the end of it. Now that almost works, but when the Rigidbody2D of that rotating firing rectangle is dynamic, it stays in place (but shoots accurately and well) instead of following the character. When I set it to kinematic, it follows the character, but whenever I fire or walk, I can not rotate the rectangle and I'm stuck firing in one direction until I stop walking/shooting, then after a delay it lets me aim again.

I can't figure out why it has an aim delay when it's kinematic and why the rectangle doesn't follow my player when it's dynamic. To attach it to my player I dragged it onto the player in the Hierarchy tab. I'm new to Unity so I'm sure it's something simple.

[onyx night]

Just fixed the delay when shooting my removing a 2Dcollider on my character, so I can aim while shooting still instead of it locking the aim while shooting. but my aim still gets locked up when I walk. this is with my aiming rectangle as kinematic. Dynamic still works perfectly but just doesn't follow my character like kinematic does, it stays in place.

[onyx night]

fixed it by using the dynamic barrel, which originally didn't follow my character, but i added

"rb1.MovePosition(playerRb.position);"

rb1 is my barrel and playerRb is my player so it just follows the player, albeit like a frame or two later, but it's not noticable once i make the barrel invisible.

[primal orchid]

I don't know why you need the rigidbody on the weapon tho

[ashen brook]

Does anyone know if grids and tilemaps can be put into asset bundles?

I'm looking for an easy way to let players build custom maps and it seems like it'd be a pretty good way to do it

[still tendon]

This is probably a roundabout way of doing it but I swear I've seen scenes included in asset bundles, would you be able to have them set up in a default scene or something?

[onyx night]

do i not need a rigidbody to have it rotate (and subsequently rotate the firepoint to where the mouse is aimed)?

[primal orchid]

yep

you can just use transform.rotate

to rotate the firepoint you can just parent it

[subtle geyser]

        LTSeq sequence = LeanTween.sequence();

        sequence.append(LeanTween.move(gameObject, _startPosition + _direction, tweenDuration).setEaseInOutQuad());

        sequence.append(LeanTween.move(gameObject, _startPosition, tweenDuration).setEaseInOutQuad());

I've been trying to make a "bump attack" animation using LeanTween sequences:

Player is at 0, 0 <-- This would be the start position
Enemy is at 1, 0
Player moves to the right (direction is Vector2(1, 0))

For some reason the player will move from 0, 0 to 2, 0 during the first move action and then to 1, 0 on the second move action. Any ideas as to why this could be the case?

[craggy kite]

Cause you are using easing, did you check it gets completed correctly? What happens if you half the duration or double?

[subtle geyser]

It does the same thing regardless of speed, it just does it faster or slower is all but the positions are the same

I had pretty much the exact same code on another project and it seemed to work as intended which is extra confusing

Actually I think I may have figured it out

[woeful sentinel]

Sometimes Leantween.sequence can be an ass... try to chain it with .setOnComplete instead

also your second sequence without + _direction

[lyric snow]

how can i see how many objects are in collision to a gameobject using OnCollisionStay2D()?

[dense flame]

It’s easier to have private int collidedAmount
Then increase it in OnCollisionEnter2D and reduce it in OnCollisionExit2D

[snow willow]

Don't use OnCollisionStay. Do what nyancode said, or use a HashSet<Collider2D> to Add colliders in OnCollisionEnter2D and remove them in OnCollisionExit2D. You can check the Count of the set to see how many are currently intersecting

[lyric snow]

if i spawn an object inside the collider of an object will that call the OnCollisionEnter?, and when i delete it, will it call the OnCollisionExit? cause im not moving them into the collider, im just creating them and destroying them inside the collider.

[snow willow]

Test it and find out 😄

[lapis fiber]

how do i fix that the objects are overlapping even though they have a circle collider on, like when the objects start to stack up they all start phasing into eachother and glitching all over the screen

[craggy kite]

You might have to update the physics frequency in physics player settings, maybe add a bit of tolerance too

[snow willow]

make sure you're moving your objects in a physics-friendly way

no animators, no transform.position, no transform.translate

[lapis fiber]

How do i fix this + the objects just keep spinning in place, ive tried implimenting what u guys said but cant really figure it out

[digital raven]

For a tilemap, does set tile ignore pivot points and positioning?

[lapis fiber]

ignore this i fixed it

[digital raven]

Man... this tilemap stuff is all screwed up. I used set tile to set a tile and it filled the tile with half a tile. Use the pallet brush to paint over it and then run the exact same script again and it puts it in the right spot. Is there something I am missing?

[wooden ruin]

Is there a simple way to draw a (completely visual) line between 2 points? I need 2 objects to be connected, preferably with a texture able to be added

[digital raven]

Should be a debug line. https://docs.unity3d.com/ScriptReference/Debug.DrawLine.html

op

oh, you mean a rendered line

[wooden ruin]

yea

[digital raven]

You would use the line renderer.

[wooden ruin]

alright, ill google that, thanks

[digital raven]

https://forum.unity.com/threads/draw-a-line-between-two-game-objects.127759/

I can't help much with the code. I'm a short bus person and use Visual Scripting.

[rocky crystal]

How do people use tilemaps to create maps with walls without manually adding rigidbodies to all of the walls to prevent people from walking through them?

[lapis fiber]

ive coded it so that every 5 seconds an object spawns somewhere on the dotted red line at the top, but i want it to be that if theres already an object on that red line (y = 3) then it wont spawn. Can anyone give me an idea to do this?

[still tendon]

You could add a trigger collider to the line to check what objects are currently on the line. Create a list of GameObjects and OnTriggerEnter2D() {Add object to list}. Then OnTriggerExit2D () {Remove object from list}
