thanks

[olive cloak]

Hello, im new to unity and im trying to add a player, but when i add boxcollider 2d and riggid body 2d it just disapper when i run the game

[late viper]

its falling through the floor, add a collider to it

[olive cloak]

there is a collider

[late viper]

on the floor?

[olive cloak]

let me check, unity crashed

how to i add a collider to the tile map?

i found the problem

the chrattar spawned inside the collider

[limpid drift]

 animator.SetFloat("X", runspeed);
        if (Input.GetKey("d") || Input.GetKey("right"))
        {
            rb2d.velocity = new Vector2(runspeed,rb2d.velocity.x);
            if (Mathf.Abs(rb2d.velocity.x) < 0.001f)
                
            spriteRenderer.flipX = false;
        }
        else if (Input.GetKey("a") || Input.GetKey("left"))
        {
            rb2d.velocity = new Vector2(-runspeed,rb2d.velocity.x);
            if (Mathf.Abs(rb2d.velocity.x) < 0.001f)
            spriteRenderer.flipX = true;
        }
``` can someone tell me whats wrong with me code because my player does not run left to right anymore instead it does this

[turbid heart]

rb2d.velocity = new Vector2(runspeed,rb2d.velocity.x);
you're setting your velocity on the x and y axis. you set your runspeed to the x-axis, and the rb2d.velocity.x to the y axis @limpid drift

[limpid drift]

how do i set the rb2d.velocity.x to the x axis?

[turbid heart]

when you assign a Vector2 to your rb2d.velocity, it's new Vector2(yourXVelocity, yourYVelocity)

do you know what velocity is?

[limpid drift]

speed right?

how fast it goes and stuff

[turbid heart]

speed with a direction

you assign velocity like this new Vector2(yourXVelocity, yourYVelocity)

so if you only wanted to move it on the x axis, set your Y velocity to 0

[limpid drift]

ooooh

so it should be ```csharp
rb2d.velocity = new Vector2(runspeed,0);

atleast thats what i think?

[turbid heart]

try it and see

[limpid drift]

now its acting really weird

for some reason it worked when i made it ```csharp
if (Input.GetKey("d") || Input.GetKey("right"))
{
rb2d.velocity = new Vector2(runspeed,rb2d.velocity.y);
if (Mathf.Abs(rb2d.velocity.x) < 0.001f)

        spriteRenderer.flipX = false;
    }
    else if (Input.GetKey("a") || Input.GetKey("left"))
    {
        rb2d.velocity = new Vector2(runspeed,rb2d.velocity.y);
        if (Mathf.Abs(rb2d.velocity.x) < 0.001f)
        spriteRenderer.flipX = true;
    }

but i got told thats wrong

but if i make it ```csharp
rb2d.velocity = new Vector2(runspeed,0);

[turbid heart]

yeah, i dont know your full context, i'm only assuming you want to move your player left and right, instead of diagonally

hang on

I might have misunderstood you

I'm sorry

[limpid drift]

yeah i want it to move left and right

[turbid heart]

you would want rb2d.velocity.y in your y velocity to maintain its y axis momentum, so you can put that back

yeah, sorry. you should revert back your code for now, I have no idea

is there a place you add to your y velocity?

[limpid drift]

yeah so when the lines were ```csharp
rb2d.velocity = new Vector2(runspeed,rb2d.velocity.y);

but when i change it to ```csharp
rb2d.velocity = new Vector2(runspeed,rb2d.velocity.x);

i honestly dont understand this anymore

[turbid heart]

can you please take a video of this midfloat animation? @limpid drift

[limpid drift]

https://gyazo.com/7940382327a4a39b9da1d954fb49b9fd

[snow willow]

why would you put the x component of the velocity into the y component?

[limpid drift]

thats what i got told to do in a other discord

they said this was wrong

because of the rb2d.velocity.y should be rb2d.velocity.x

and when i changed that my player started floating like the vid i just sent

[snow willow]

I think they were talking about in the if (Mathf.Abs(rb2d.velocity.y) < 0.001f) part

not the part you changed

[limpid drift]

oh

so the ```csharp
if (Mathf.Abs(rb2d.velocity.y) < 0.001f)

 if (Mathf.Abs(rb2d.velocity.x) < 0.001f)

[snow willow]

yes... of course - you want to check the horizontal velocity of your character to flip it, right?

[limpid drift]

but thats the part that confusses the fuck out of me

because ```csharp
if (Mathf.Abs(rb2d.velocity.x) < 0.001f)

does not flip

if (Mathf.Abs(rb2d.velocity.y) < 0.001f)

it does flip

and i dont understand why the hell it works like that

[turbid heart]

why do you do Mathf.Abs? I can see you set your x velocity to -runSpeed

[snow willow]

oh yeah lol

[turbid heart]

Mathf.Abs makes it never negative @limpid drift

[snow willow]

don't use Abs

it's absolute value

[turbid heart]

and.. why do < 0.001f? why not just < 0f?

[limpid drift]

so ```csharp
if (rb2d.velocity.y)<0)

[turbid heart]

no

[snow willow]

x, not y

[turbid heart]

the x axis

[limpid drift]

ah yeah x my bad

gives me this error

so no idea why it does allow it with mathf.abs

[turbid heart]

check your brackets, and you dont need a ; there

you didnt put one for your Input.GetKey if, so why would you need one there? @limpid drift

[limpid drift]

found it had one ) too many

and the ;

A 2D character of mine walks inverted, what can I do to fix it?

[dusky wagon]

Another simple question, but can you offset a sprite from its center point? In my script the character gets flipped if hi changes direction, but because my character has a long sword in the front it looks like the entire character changes its position

Nevermind I figured it out

[viral moss]

1. The if statement is irrelevant, you could take it out and it'd work fine.
2. Can you check the axis input? (Edit -> project settings -> Input manager -> Horizontal) and check what the buttons there say?

*and that invert is not turned on

[cursive heart]

The if is for the rigidBody of a ball, that is, if I was moving it on a slope and then stopped moving it, it wouldn't keep going down, it would stop

[viral moss]

ah okay

[cursive heart]

And I just went to the input from the axis and managed to configure it, thanks for help

[silver walrus]

ANything wrong with this code? The ''impulse'' is not happening when the player slides in the wall and press space

[vocal condor]

Separate the logic from input polling.

Input polling should be handled in Update and Physics should be dealt with in Fixed Update. Not doing so would produce strange effects (polling in fixed update will have you missing inputs - whereas doing physics in Update will not properly interpolate; causing delays)

[left nest]

I am trying to make a certain gameobject appear and then after a few seconds disappear and have a new gameobject appear but I am having problems. I am using Invoke to start certain functions to begin those functions, but in unity it comes up with the error message: "_ManagerScript.LBA() is a method which is not valid in the given context" Here is my code:

using UnityEngine;

public class _ManagerScript : MonoBehaviour
{
    public float LBA_Lifetime;
    public float LBA_Warntime;
    public GameObject LBA_Warn;
    public GameObject LBAA;


    void Awake()
    {
        LBA.SetActive(false);
        LBA_Warn.SetActive(false);
        Invoke("LBAW", LBA_Warntime);
    }

    void LBAW()
    {
        LBA_Warn.SetActive(true);
        Invoke("LBA", LBA_Warntime);
    }

    void LBA()
    {
        LBA.SetActive(true);
        LBA_Warn.SetActive(false);
    }
}

How can I fix this?

[late viper]

how are you calling LBA?

[left nest]

Invoke

[turbid heart]

which line has the error?

[left nest]

40:52

[turbid heart]

we cant see line numbers in discord. which line is it

you can double click the error in the console and it'll take you to it

[left nest]

LBA.SetActive(false); to LBA.SetActive(true);

[turbid heart]

I see it. LBA is your method, not your gameobject. you're trying to use your method to SetActive(false)

[left nest]

oh

[turbid heart]

maybe a lesson in naming your methods and variables to something more intuitive

[left nest]

ok thank you

thank you!

[turbid heart]

by the way, are you using Visual Studio?

[left nest]

yes

[sick lagoon]

Hey, I am making a 2D platformer for Android.
When running it in the unity Game View, the movement is smooth and good,
but when exporting it to my phone the player jumps fine but he moves 100x slower.

I cant attach code tho, it blocks me

Heres the code for the player controller: https://pastebin.com/1djpVZ9d
Am I missing a deltaTime?

[late viper]

I suspect the way its reading joystick.Horizontal on your phone is different from what you're expecting

[sick lagoon]

Hmm, makes sense

Ill debug it and update about it

[sick lagoon]

From what I see, they give the same value

[late viper]

is the horizontalVelocity the same?

[sick lagoon]

Checking

It looks like when on my phone the ground has so much more drag then in unity

As when im jumping it starts accelerating but on ground not

[sick lagoon]

Ok, I got a workaround, I added a physics2d material and its now only 10x slower then in unity itself, its better then 300x ':D

Tho, Im facing another problem, when landing after a jump, the character clips into the ground and bounces back up, have someone encountered this problem?

[sick lagoon]

Fixed, I had to change my tilemap collider from outlines to polygon

[sick lagoon]

I'm still open for suggestions, the workaround isn't that great :)

[marble isle]

anyone able to help me fix this?

[viral moss]

Could you be.. a lot more specific about which part is the issue?

[marble isle]

hey is there a way we can join a call or something? if you are willing. i dont want to be a burden. im having trouble with my enemies animations triggers

im pretty new to game dev so im not too sure how to explain things haha

[viral moss]

Sorry but i'll pass </3 in a call w/ friends.
But you should probably try to describe what's supposed to happen

[marble isle]

ok well when the enemy come towards the player it is meant to play the run animation which i dont know how to implement the code and when being directly above or below the enemy i dont want it to spaz out like it is in the video haha

[viral moss]

Alright well for the animations, I would recommend watching a guide on how they work in general.
https://www.youtube.com/watch?v=hkaysu1Z-N8
I think this one's p decent.
As for the 'spaz', I assume it's because the enemy is trying to reach the players location.
You could do a check for if it's very close to the player with something like "if transform.x is between player.x -0.5 & player.x +0.5" so it would stop chasing the player if it's basically on top or below them

[marble isle]

thnx. ill check it out

[marble isle]

this tutorial uses the character you play as and i think it uses different code and isnt working for my enemy npc character

[pseudo wave]

hello does anyone know why my MovingBlock function is not working?

the playerScript.change.x and playerScript.change.y are the raw inputs of the player direction

so it gives +1, -1 or 0

the logic is moving the block in the direction the player is facing 1 unit, when pressing Z and player is in range

player is in range is working properly

the first line of the while loop inside the IEnumerator is just while the distance is > than a very small amount (Mathf.epsilon)

[runic cipher]

[tilemap question] Hi everybody. I'm trying to extend tilebase to store data within each tile on a tilemap. Does each tile exist as its own separate object, meaning I can store data in each individual tile, or are all tiles copies of a base tile? Thanks!

[dense flame]

Each individual tile stores it’s own value if you use scriptable tiles

[runic cipher]

Does this also hold true for the value stored in tileData, ie the sprites and such?

[marble isle]

my characters animation wont go back to idle even tho i used else

anything i have done wrong?

[snow willow]

It's going to come down to how your Animation Controller state machine is set up to react to these parameters

you need to have the appropriate transitions set up

[knotty barn]

@marble isle You sure you are calling ChasePlayer when the else condition is true?

[snow willow]

also that

[marble isle]

isRunning true causes the run animation and false causes idle animation

[snow willow]

I would play the game with the animation window open and the Animator selected,. and watch the state machine

you'll want to make sure the correct parameter values are set at the correct time and that the state machine is properly transitioning to the desired states

[marble isle]

im pretty new to game development so im struggling a little here haha. i have been experimenting for hours and finally got the run animation to work, it just wont go back to idle

[snow willow]

What I just said is, in my opinion, the best way to debug animation issues

[knotty barn]

Is the value changing in Animator?

[marble isle]

could i upload a video for you to have a look. not to sure whats going on

[knotty barn]

Just look for if the isRunning bool is changing in the animator

You should see the currently selected GameObject's animator state in the animator window while you are in play mode

[marble isle]

or could one of you help out on a call. i have alot of bugs right now haha. it now only starts the animation if i am on the right of the sprite

but continues the run animation forever

i believe its my code but idk where to start in fixing it. been tryna fix this for hours

[snow willow]

sounds like you have more than one issue going on. Try to focus on one thing at a time

[marble isle]

this is whats happening

@snow willow @knotty barn

[snow willow]

the transition you currently have open that goes from the run state to the idle state has the wrong parameters

That should just be isRunning -> false

delete the "notRunning" parameter. It's confusing and redundant. Delete it entirely from the animator

isRunning can already be true or false

[marble isle]

god im dumb haha. i was messing around with other perimeters and must have forgotten to change one back. im super fresh to game development so im literally rocks for brains haha.

[marble isle]

just fixed that up but it still doesn't transition to idle when it should

holy shit i fucking did it

[silver walrus]

Hi! I followed a tutorial on a wall jump code and got this. Now, for some reason it is not working. I can jump into the wall, the character starts sliding but no matter what i press, nothing happens. Any ideas?

Thx in advance!

[fallen flicker]

Maybe instead of using Keycode.Space try and use Input.GetKeyDown("Jump") and see if that fixes it

[turbid heart]

for that to work, they'll need to have defined a "jump" key, I think

[silver walrus]

Got fixing it, I just had to remove the WallJump mechanic and leave only the wallhop

[fallen flicker]

You'd have to define one but I believe it is auto set as the space bar

Nice

[silver walrus]

also, changing to Jump helped

[untold fox]

Can someone help me with a script ?

Im trying to make the player jump but when im trying to jump it doesn't work

Thats the script

using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour {
    public float movementSpeed;
    public Rigidbody2D rb;

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

    float mx;
    bool isGrounded;

    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 && groundCheck.gameObject != null)
        {
            return true;
        }

        return false;
    }
}

There are no errors

Its just doesn't work

[craggy kite]

Do you check for isGrounded? Like debug.log it somewhere so you know it is true. also just increase your force to something super high so you k now, it is working and not limited by mass or drag

[untold fox]

I know that the error is there
if (groundCheck != null && groundCheck.gameObject != null)

[craggy kite]

So did you check both? @untold fox just debug.log both statements and see what you get

[untold fox]

Yes I checked both

[craggy kite]

Are they both not null?

[untold fox]

Yes

[craggy kite]

So it is returning true?

Did you debug.log your jump, to check it is being called?

[untold fox]

wdym

[craggy kite]

Debug.Log("Jump") in ypur function...

[untold fox]

Can I dm u ?

[craggy kite]

Nope, sorry, working right now and I dont do DM support

[untold fox]

[bronze reef]

I have a question about coding but not directly about my code

I literally just started coding today.

And I am pacing myself literally only making a square move left and right and jump

But everything I did today I will have to look back to because I won't be able to remember it.

So my question is, Will I be able to write it off heart once I write it more and more?

[late viper]

your goal isn't to memorize how to make it move, it is to understand the concepts that make it move

but yes as you get experience it will be easier to write code

[bronze reef]

Ok. I am trying my best as I am writing it to understand what is happening, and I am understanding some things but I still don't know how everything works.

It took me 5 hours just to make a square move and jump.

[late viper]

thats fine, everyone starts somewhere

[leaden sky]

how can I change the sprite sheet that is used for an animation. So I have this sprite sheet for a player spawn. But I have it for 4 different colors. Do I have to create a seperate animation clip for each?

[craggy kite]

are they just like colored parts or total different textures/designs?

[leaden sky]

it is the same texture but a different color
so a different png but the exact same size and grid so to say

so player 1 = greedn, 2 red etc

[craggy kite]

you could just use unity to color the texture then, would be a workaround. Otherwise you could swap textures with alternate textures / sprites, check google for alternative sprite textures.

[leaden sky]

thanks I will see what i can find

[twin anvil]

How can I make it so whenever my mouse is on the left side of the screen my character is facing that direction? I don’t want the character to follow the mouse, just change direction left or right depending.

[left nest]

what have you tried so far?

[twin anvil]

I’ve looked at some forum posts about the same type of thing but couldn’t get it to work

[left nest]

Well you could so something like this:

Put this is void Update and make a public float called offset place it on the player and if it doesn't fully face the mouse increase offset and eventually it will,

Vector3 difference = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
float rotZ = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0f, 0f, rotZ + offset);

[twin anvil]

Ok thank you so much

[twin anvil]

I actually just got home, tested this out, and it's not necessarily what I wanted. I want it to only be able to face left and right, not up, down, etc.

[marble isle]

anyone know why this is happening?

[hollow crown]

assets cannot reference in-scene data

so those references will be prefab overrides in the scene

[marble isle]

i want to be able to remove the enemy npc from the scene but be able to just drag and drop it back in without having to re-assign the script every time

is that possible?

[hollow crown]

Generally whatever spawns the NPC should have the in-scene references

and pass them to the NPC when they are instanced

[turbid heart]

Look into ScreenToViewportPoint and use it with your mouse position

Viewport is what your camera sees and goes from 0 to 1
So 0.5 would be the center of your screen. Sooo < or > 0.5 should give you left and right side

[marble isle]

nothing spawns it haha i have just placed it there. im new to game dev

[honest palm]

Bit of an odd question. Does anyone know how I might create a vector from an angle and a direction?

Currently I'm trying to make a character turn to face a left and right angle from their current up position. Like a sort of scan or sweep across their field of vision. But to do so, I need them to be able to look to the left and right of their current facing direction by a given angle.

[hollow crown]

There is no simple way to have it assign the reference when you manually drag and drop it

[marble isle]

well that sucks haha. if i wanna make it so it spawns in lets say in an infinite procedurally generated map, would i have to make another scene for the game?

[left nest]

you could code it to go to the position of any gameobjects with the tag player

or raycasts to detect if the player is near to come and attack it

[hollow crown]

Not sure what you mean, you don't need multiple scenes, the entire issue here is that references can only exist in the scene, or to or between assets.
If the spawner has the in-scene reference, and references the prefab asset, then it can configure the instance when the prefab is spawned

[marble isle]

oh i think i get it. is it possible to have it in here but not actually on the game (if that makes sense. sorry if it doesnt haha i honestly have no idea what im talking about)

[marble isle]

how would i go about removing it from the game but keeping it in there?

[hollow crown]

You can disable the gameobject

[twin anvil]

wait what exactly are you talking about? I wan to change the rotation of my player not the camera.

[turbid heart]

Yeah, but i was addressing how to check when your mouse is on the left or right side of the screen

[twin anvil]

oh got it

that makes sense

[turbid heart]

Is this 2d? Flipping your sprite is the easier part 🙂 you can look it up

[twin anvil]

it's 2.5d yeah

i think ik how to flip it

just rotate it, but i still don't know how to add the mouse on the left and right to the rotation

[left nest]

to flip it you can just invert the x scale

[twin anvil]

yeah

that's not the part im having the problems with

it's the checking which side of the screen the mouse is on

[left nest]

ah

[green tapir]

https://forum.unity.com/threads/mouse-position-for-screen-space-camera.294458/ will this do what you want?

[twin anvil]

I don't think so. Does this make the sprite follow the mouse around directly?

[green tapir]

no. just to clarify, is this pure 2d or 2.5?

because one you have to project the mouse.

[twin anvil]

2d

im doing it in a 2d manner

[green tapir]

well then that should pretty much do that?

[left nest]

isn't that putting the sprites position the same as the mouses position

[twin anvil]

are you referring to it make something rotate around to follow the cursor? because if so, that's not what i need

i just need the sprite to flip from left to right

[green tapir]

oh

[twin anvil]

if the cursor is on the left or right, not follow it directly

[green tapir]

so to clarify, you want the sprite to flip if the mouse is on the left side of the screen?

[left nest]

to get this straight you want to the sprite to to face the direction the mouse is so if the mouse is the right of the player it faces right if the mouse is the left of the player it faces left

[twin anvil]

yes

[green tapir]

and then back when it goes back to the right?

[twin anvil]

indeed

[left nest]

ok

[green tapir]

are you rotating or flipping anything anywhere else, just to figure out how I want to give this to you?

because there are a lot of ways to skin this cat.

[twin anvil]

im having the player sprite flip, but have the hand also rotate around him towards the mouse

so the player will flip left and right only

and the hand will follow the cursor directly

[green tapir]

does it currently do a sprite flip?

[twin anvil]

?

[green tapir]

like, it doesn't currently flip at all?

[twin anvil]

no

when i move the mouse the player doesn't flip at all

[left nest]

when the player moves right does it flip to face right and when it moves left does it flip to be left?

[twin anvil]

no, i want the player to be able to walk backwards

[green tapir]

okay, so that bit I gave you above is half the equation. You want to take that mousetoscreenspace variable, and then get your resolution, then you can set up an "If it's less than half the res, sprite.localScale *=-1" or however you want to do the flip

[twin anvil]

so when he moves or pressed wasd it doesn't change

ok

[green tapir]

just using the mousetoscreenspace.x

not the whole vector3

@twin anvil var screenPoint = Input.mousePosition; screenPoint.z = 10.0f; //distance of the plane from the camera var tracker = Camera.main.ScreenToWorldPoint(screenPoint).x; print(tracker); var reso = Screen.currentResolution.width; if (tracker < 0) { transform.localScale = new Vector3(-1, 1, 1f); } else { transform.localScale = new Vector3(1, 1, 1f); }

this seems to do what you want basically.

[twin anvil]

it seems to be working how i want it, but the center of the screen is for some reason offset to the left a little.

oh i think i know why

would this work with a camera that follows the player?

[green tapir]

Yeah, though it might goof if the distance to the screen changes.

but should basically work in 2d.

I'll confirm.

seems fine

[twin anvil]

for me whenever i move the player it drifts off from where the center of the screen is

i even watched the tracker that you put in, and whenever i move to the right without moving my mouse the number goes up

[green tapir]

hmmm.

okay

        {
            sprite.transform.localScale = new Vector3(-1, 1, 1f);
        }
        else
        {
            sprite.transform.localScale = new Vector3(1, 1, 1f);
        }```try that

note that this does require the game to actually have a set resolution.

just "16:9" or free aspect won't work.

[twin anvil]

it's telling me sprite doesn't exist in the current context

[green tapir]

oh, sorry, that's a holdover from trying something else.

just get rid of sprite.

[twin anvil]

oh ok

it's works!

[green tapir]

actually, just do Screen.width

[twin anvil]

thank you so much dude

[green tapir]

Screen.Width just takes the cameras current res, which will probably work better for you.

Seems like.

for this context

[twin anvil]

ok got it

[green tapir]

what was that about rotation?

[twin anvil]

what about rotation

[green tapir]

you said something about rotation I thought. If no, have a good one, hahaha

[twin anvil]

no it was just another way i was going to flip the sprite

but this works fine, have a good one

thank you a lot

[twin anvil]

ok, im back again

I'm trying to make my players hand rotate around his body

but the problem i'm having is, is when the hand/mouse gets above the character at a 90 degree angle and goes past it the hand goes to the feet area instead of the head

ik what the problem is but don't know how to fix it

it has something to do with the thing I just had a problem with, whenever the character turns around (the scale is changed to a negative) it also changes the scale of the hand, and if i take the hand out of the children of the player it won't move with the player

[marble isle]

i have my enemy face my character when on their left or right but when im above the enemy it has a spaz. is there any way to fix this. i want it to go idle when the playable character is directly above or below so when writing if (transform.position.y < Player.position.y) the enemy goes idle even if i do the tiniest jump (this code was removed before making the video so i could show the spaz haha)

[vocal condor]

transform.position.x < Player.position.x + minDist

[marble isle]

where should i put that line of code?

[vocal condor]

Where minDist is the minimum offset before acting.

[vocal condor]

It's relative to your code provided.

[marble isle]

im pretty new to game dev so im not very knowledgeable in the language

should i put my code in here?

[vocal condor]

Basically if the player is left of us PLUS some minimum distance, go left. Else if the player is right if us PLUS some minimum (maximum of you're wanting to think of it as coordinates), go right.

[marble isle]

ah. i have all of that set up. the character already follows me. i just want it to go idle when im directly above or below it

[vocal condor]

Which is why I mentioned the minimum and maximum distance before changing directions; spazzing?

I am not able to watch the video and am simply assuming based on what you said.

[marble isle]

when i am directly above or below the enemy it doesnt know which way to face as i am neither on the left or right of it so it just looks both left and right at a very high speed haha

[vocal condor]

It knows which way to face.

You simply need to set a minimum.

So if it's within a minimum it doesn't bother chasing/facing your player.

I've got to go now, good luck.

[marble isle]

ok thnx

[worldly leaf]

how to fix this

[hollow crown]

select something and press F

then zoom into it

[worldly leaf]

@hollow crown ah thank you dude

[torpid locust]

Hey! I'm trying to make a game where when I pickup a key it changes the color of one game object(door) and I worked out how to make it disappear but I don't know how to connect this with another object because I used a ontrigger thing to make the key disappear.

[leaden sky]

a few different options but if the key has a reference to the door (through serializefield or tag) it can call a method on it before disappearing

[radiant wigeon]

How would I make a sprite (the player) land on another sprite (the map)?

Would changing the z axis do anything?

could I use ```cs
if (Physics.OverlapSphere(groundCheckTransform.position, 0.1f).Length == 0)

to check if its on the ground?

no that wont work

wait yes it does nvm

wait nvm again

[radiant wigeon]

can someone help me with my original problem?

Like how would I make a 2d object stop another 2d object from falling through it?

[plush coyote]

put a 2D collider on both objects..

and a rigidbody on your player

[radiant wigeon]

I have a Rigidbody but thx

@plush coyote does it matter which type of 2d collider?

[plush coyote]

it has to be a Rigidbody2D and a Collider2D

no it doesnt really matter what type of 2D collider

as long as it sort of matches the object

capsules and boxes are the most common

[radiant wigeon]

How would I get Rigidbody2d in the script with GetComponent<>();?

[plush coyote]

just like any other component, so yes

[radiant wigeon]

I get this error when I do:

I realized after I sent the msg lol

I get this err now

}

Assets\Scripts\Player.cs(28,59): error CS1503: Argument 2: cannot convert from 'UnityEngine.ForceMode' to 'UnityEngine.ForceMode2D'

[plush coyote]

its exactly as it says, the 2D version of addforce uses ForceMode2D

not ForceMode

and you should use Impulse for the forcemode2d type instead

since I dont think VelocityChange exists in the 2d version

[radiant wigeon]

yea VelocityChange wont work

[plush coyote]

if you want it to actually just completely change the velocity than set the Y velocity to 0 before you jump, then add impulse force

[radiant wigeon]

How would I do that?

[plush coyote]

Vector2 newVel = rigidbody2DComponent.velocity;
newVel.y = 0f;
rigidbody2DComponent.velocity = newVel;

since you cant directly set the y value, you have to do that

as for the impulse, you just need to switch ForceMode to ForceMode2D like I said earlier

then Impulse instead of VelocityChange

[radiant wigeon]

ok

wait im still confused

now I just float through the block very slowly

@plush coyote

I just need to know how to let a block land on another block

[plush coyote]

if you dont understand, look on google for basic explanations of how physics components work in unity

[radiant wigeon]

lol it turns out I forgot to attach a collider

[still tendon]

im trying to make a top down fishing game but i dont know how to make the fishing mechanic, i want it to be randomly base for example one fish has A 2% chance of spawning and another has 5% chance of spawning, anyone have any good code? or video tutorial that would help

[dire salmon]

how could i convert this to be smooth turning with a turn speed?

Vector3 dir = Input.mousePosition - pos;
float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);```

[brazen snow]

Can someone help me with this ?

When im trying to jump again it doesn't work

[dire salmon]

code?

[dusky wagon]

How can I make an object with a rigid body be harder to push without making it super heavy?

[snow willow]

is it resting on the ground?

Maybe give it a physics material with more friction?

[dusky wagon]

Ive tested a bit and the only thing I found to prevent the player from throwing the object around like nothing was to make the object very heave but that made it fall to the ground instantly-

[dusky wagon]

Oh I will try that

[gilded rover]

do you have any tutorials for a 2d shooting system?
like, can you recommend any?

[turbid heart]

dont crosspost. and have you googled?

[gilded rover]

yea

[turbid heart]

well you need to be more specific on the kind of 2d shooting system you're after

[gilded rover]

all of them are platformer things, I want to pick up guns

and shoot them

[turbid heart]

and worse come to worst, break it down and google individual features

[gilded rover]

ohk

[dusky wagon]

Doesnt seem to work

[snow willow]

how are you pushing the object

[dusky wagon]

With the player

[snow willow]

Yes but how

be specific

physics joints?

Moving a rigidbody with forces?

[dusky wagon]

Second one

The rigid body of the player gets moved with forces

[worn gate]

I'm trying to make it so when I click on the object it casts a 2d raycast up until it touches something and switch position to said thing - 0.7.
So far clicking does nothing.

public class SpikeBehaviour : MonoBehaviour
{
    public bool SwitchedUp;
    private void OnMouseDown()
    {
        RaycastHit2D hit = Physics2D.Raycast(gameObject.transform.position, Vector2.up);
        if (hit.collider.gameObject.CompareTag("Switchable")) 
        {
            Debug.Log("Switched?");
            gameObject.transform.position = new Vector2(gameObject.transform.position.x,
            hit.collider.gameObject.transform.position.y - 0.7f);
        }
    }
}

Can I get any help? I'm confused

[snow willow]

If you put a Debug.Log outside of the if statement does it log?

[worn gate]

Yes

[snow willow]

Ok then I guess the raycast just isn't hitting anything

[worn gate]

uh it's a simple isometric diamond

scale 1, 3

[snow willow]

where is the pivot of the sprite? (i.e., where is transform.position

maybe it's not centered so the ray isn't exactly where you expect it to be?

What are you expecting the raycast to hit that it is not hitting?

[worn gate]

here's the scene

I just want the diamond's raycast to hit the ceiling

[snow willow]

so "Switched" is not logging?

[worn gate]

sprite's position is 0, -3.8

no I don't think so

[silver walrus]

Can I get some help please?

[dense flame]

When it’s on air you should multiply input by airSpeed instead of moveSpeed

[worn gate]

Can anyone help me with my raycasting issues?

[hardy heart]

Hey guys, how to make that player will move to mousePos in NavMesh 2D?

[dense flame]

There is no built-in NavMesh2D

If you’re talking about some specific tool you downloaded then say which one it is

[hardy heart]

NavMesh in 2d game

[snow willow]

Just use the mouse position in the world as the navmeshagent destination

[worn gate]

Alright i've completely reworked my code but a new problem arose :

using System.Collections.Generic;
using UnityEngine;

public class SpikeBehaviour : MonoBehaviour
{
    public bool Switchable;
    public GameObject SwitchableObject;

    void Update()
    {
        RaycastHit2D hit = Physics2D.Raycast(gameObject.transform.position, Vector2.up,        
        Mathf.Infinity);
        if (hit.collider != null)
        {
            if (hit.collider.gameObject.CompareTag("Switchable"))
            {
                Switchable = true;
                SwitchableObject = hit.collider.gameObject;
                Debug.Log("Switchable");
            }
            else 
            {
                Switchable = false;
                SwitchableObject = null;
                Debug.Log("Not Switchable");
            }
        }
    }
    void OnMouseDown()
    {
        if (Switchable == true && SwitchableObject != null)
        {
            Debug.Log("Switched?");
            gameObject.transform.position = new Vector2(gameObject.transform.position.x, 
            SwitchableObject.transform.position.y - 0.7f);
        }
    }
}```

Now, in order to make onmousedown work I need a collider for my object

but if I put a collider for the object, the raycast doesn't detect the tag anymore

[snow willow]

Time to learn about layers and layer masks

[worn gate]

alright i'm gonna try to do that! Sound interesting

[snow willow]

Basically you can add a mask to your raycast that lets it only hit obejcts on certain layers of your choosing

so you'd put your "Switchable" objects on a special layer

and have your raycast only look for that layer

[worn gate]

Oh ok, thanks

i'll try to look it up and figure it out, if I have more issues i'll ask here again I suppose

So I essentially change the layer of the object that casts the ray if it has a collider so that it ignores completely that collider and tries to hit the next one?

[snow willow]

there is no such thing as "the object that casts the ray"

[worn gate]

what do you mean?

[snow willow]

I'm saying put the objects that you want the raycast to be able to hit into special layer(s) that the raycast is looking for with a mask

[snow willow]

I mean you just call Physics.Raycast and there's no concept of a "source object" for it

[worn gate]

Oh right, i'm just assuming the GameObject is the source object since the script is attached to it and the starting position is the GameObject, what you're saying makes total sense, thanks.

[full oyster]

I have this problem where I can't get 4 directional movement when making a RPG game. I get 8 directional movement. How do I fix this

[snow willow]

what is the control scheme?

What do you want the behavior to be when the user is pressing two directions at the same time?

[full oyster]

I want them to move the direction they first pressed. For example, if I press 'w' then 'a', I should move forward

[wet umbra]

you need to negate other keypresses while the primary one is held down

if key down: move and set other keydown conditions to false
if key released: dont move and enable other keydown conditions

[radiant wigeon]

Can someone help me with this:

[rocky temple]

I'm assuming your problem is you don't want it to flip?

[radiant wigeon]

yes

[rocky temple]

there's a "freeze rotation" checkbox in rigidbody

[radiant wigeon]

ok

[radiant wigeon]

How would I remove friction again?

and how would I let a rigidbody jump while moving horizontally?

[radiant wigeon]

Like where would I drag the pyhsics material to?

[wet umbra]

you want to use momentum or have the player control movement while in the air?

[radiant wigeon]

player control movment

[wet umbra]

I think that kind of behavior come naturally, if you can move your character in the ground, it should occur in the air

[candid flame]

Can someone help me out? I added a package called "collections" before going to start animating a 2D character and this just happenned

[hollow crown]

You're going to either need to upgrade or downgrade it to a version that has the Length property

they quickly deprecated it and removed it, it's irritating

[candid flame]

sorry for not being an expert in unity but, how exactly can I do that?

[hollow crown]

I'd have to check the changelogs to find out what version has it, it's in there

there's a dropdown next to the name in UPM

[lean estuary]

2D animation package was merged with 2D Sprite

so having both would conflict

[hollow crown]

This is the first I'm hearing of this

I don't think that's the issue, I've had this one specifically

it's just Collections being annoying

[candid flame]

pretty much, and you cant just delete the warning in the console

pretty irritating so yeah

[lean estuary]

oh yea sorry, not animation that was about IK

[candid flame]

so the main solution is to downgrade the collection´s version right?

[hollow crown]

Downgrade to 0.6.0 or below

[lean estuary]

You can try clearing packages in Library as well

[hollow crown]

You may get away with 0.70, but I am unsure. The changelog has the same deprecation notice on both 0.7.0 and 0.7.1

[snow willow]

Yeah I ran into this recently it was very unclear and very annoying

[candid flame]

ill try, but still, its very odd

I also have a collection package in a different project, with the same unity version

but without this problem

[hollow crown]

It's a mix of the 2d animation package's version, and the version of collections

if you can update the 2d animation package, do that first

[candid flame]

that might be a solution, ill have a look

[hollow crown]

(it should tell you if it can be upgraded)

[candid flame]

seems you were right, I have to upgrade it to 3.2.9

I had it in 3.2.4

[hollow crown]

👍 should fix it

[candid flame]

seems like its working now, almost 10 errors did open all of a sudden, but at least I could delete them this time

is it normal that happenned?

[lean estuary]

some errors are one time after upgrading in some cases.

[candid flame]

true

but now I have a problem after updating the collections version: it goes when swapping to the sprite editor

any ideas?

[lean estuary]

It could be related to the thing I've mentioned. IK package was merged with Animation (not 2D Sprite like I said originally) So if this was built with version before merge it might have wrong references. Probably should rebuild any IK components so they use merged new package.

[candid flame]

that actually was the problem, I just fixed

[willow current]

Does anyone know how to make a realistic-er jump physics in Unity2D?

Like when falling the player has to fall faster than the jump

But it takes the same amount of time to jump and fall, from what I see in my character

when I want the character to fall back to the ground faster than they jump

[snow willow]

In real life, objects follow a roughly parabolic trajectory and fall at the same speed that they launched from the ground at

(not accounting for air resistance)

[viral moss]

Not sure if it's exactly what you want, but the implemention in this video feels pretty natural and it's very simplistic.

https://www.youtube.com/watch?v=7KiK0Aqtmzc

[snow willow]

so that doesn't sound particularly "more realistic" to me. But if you want to do it, you can add extra force down while in the air

after reaching the pinnacle of the jump

[willow current]

ah what i mean is like, as an object is falling down the velocity incrases more

[snow willow]

that's normal gravity behavior, right?

Just constant acceleration

[willow current]

ah okay

[snow willow]

as long as you're using a Rigidbody and not doing anythig like setting velocity directly, you should get that

[willow current]

I've only used platforms in my projects so I don't see the accelartion alot

[viral moss]

If you want it to go harder you could up the gravity scale the longer the player is off the ground I suppose.

[willow current]

Also is there anyway to code animations through code or do i have to use the animation editor?

[snow willow]

Any field or property the animator can animate can also be modified directly in code

[willow current]

ah okay, thanks

[gilded rover]

yo guys

does anyone know a good tutorial for 2d shooting

[honest python]

so I have this ```cs
Lava.transform.localPosition = new Vector3(0f, -10f, 0f);

and I know it gets called

and there's nothing else controlling its position

but it just doesn't work

and I know it's not null

[grand coral]

where are you calling that line and what are you trying to achieve

[honest python]

just set the position relative to the camera

which is its parent object

[grand coral]

i see

and is it moving somewhere you don't want or just not moving at all

[honest python]

not moving at all

when I set it as a child of another object it does work tho

so

solved ig?

[grand coral]

as long as that's ok to not have it as a child of the camera then sure

not sure why it wouldn't work as a child of the camera though i've definitely done that before

[honest python]

ye so have I

void Death()
    {
        Instantiate(DeathParticle, transform.position, Quaternion.identity);
        Destroy(gameObject);
        StartCoroutine(Reset());
    }

    IEnumerator Reset()
    {
        yield return new WaitForSeconds(1.5f);


        Debug.Log("gone");
        SceneManager.LoadScene(SceneManager.GetActiveScene().name);
    }

why does this IEnumerator

never get called

[snow willow]

Because you are destroying the GameObject

[honest python]

oh

right

lol

[snow willow]

coroutines will not run on destroyed objects

[honest python]

yes that was silly

[blissful inlet]

Whats the best way to move a character, im using tranform.Tranlate and my character is just crossing the collider, is there another way, without being micro teleportacions?

[honest python]

using rigidbody velocity

[abstract olive]

Rigidbodies have a MovePosition function.

[elder minnow]

I mean, the "best" way is different for different goals you have in mind

[blissful inlet]

i tried using this MovePosition, but then the character stopped being pushed by the gravity

void Update()
{
move.x = Input.GetAxisRaw("Horizontal");
move.y = Input.GetAxisRaw("Vertical");

}
private void FixedUpdate()
{
    rb.MovePosition(rb.position + move * moveSpeed * Time.fixedDeltaTime);
}

[snow willow]

If you want gravity and collisions and everything to work properly, you'll need to move your character only with AddForce pretty much

everything else is going to basically override all the normal Rigidbody motion in one way or another

or simulate your own gravity and use MovePosition

but you won't be able to be affected by other outside forces

[blissful inlet]

AddForce worked nice, thanks 🙂

[burnt phoenix]

um can sombody help me with this im trying to make it so that the player flips by rotating but i cant get it
transform.rotation(Quaternion.Euler(180, 0, 0));

[dawn trench]

how do i rotate a sprite without affecting its transform rotation

[vagrant nexus]

you dont really

but you can put the sprite on a child gameobject

and rotate that instead

[dawn trench]

that'll be a mess

[vagrant nexus]

dont see how

[dawn trench]

i rather just duplicate it and rotate in image editor

[vagrant nexus]

how would the child object be a mess?

[dawn trench]

and use two per sprite

[vagrant nexus]

or wait

do you mean flip a sprite?

like left or right?

[dawn trench]

i wanna have the least amount of objects possible

no

that's why i said

I'll use two per sprite

with flipping

i can get the other two

but that's terrible

[vagrant nexus]

what is your actual goal, disregarding everything I said

[dawn trench]

so i wanna exactly why does unity not allow it

[ruby karma]

Do you want to rotate the sprite to any possible angle, or just flip it left/right up/down

[dawn trench]

yes any possible angle

[vagrant nexus]

then put it on a child gameobject and rotate it...

[dawn trench]

but i want it to keep moving in the same direction

[ruby karma]

and why do you not want to change the transform?

I see

[vagrant nexus]

make the parent move in the direction you want

then the child object is rotated how you want

[dawn trench]

but then I'll have to add more components to the code

[ruby karma]

You have two choices :
Tweak your movement.
Use a child object.

[vagrant nexus]

if that is going to stop you, I dont see how you could do anything

[dawn trench]

but why tf does unity now allow it what's the reason

on i mean

[vagrant nexus]

its like 2 lines of code

[dawn trench]

i have to use that in more 30 lines

but yes my method would need more

I already have like 6 components that I'm adding publically to the code

so is this the right workflow ?

[vagrant nexus]

just add a child object and put it on that, yes

[dawn trench]

having so many public variables

[vagrant nexus]

and yes

it does not really matter how many variables you have..

[dawn trench]

is there a way to read them globally

[vagrant nexus]

although they should probably be [SerializeField] private

if you dont need them in other classes

you can read them if you use GetComponent to get your script

then you can access it just as you would a class

[dawn trench]

yes I'm doing that

but i mean

without making the variables public to drop the sprites on it

can i read them from a global container

by ID

[vagrant nexus]

oh, yeah, look into ScriptableObjects probably

but like

[ruby karma]

Sprites aren't runtime resources, they are assets which shouldn't be modified at runtime. Unity offers a way to do what you want and that is via multiple objects. For it to work as you would expect, it would require a serious amount of change in how SpriteRenderer works.
SpriteRenderer probably generates flipped sprites or something similar prior to game run already 🤷‍♂️

[vagrant nexus]

seems kind of pointless since most of the time since you would just be dragging and dropping them anyway

[dawn trench]

as i said

its not really necessary for now

i know how to deal with this with no changes

just that when i use it later on a much larger scale

guess I'll have to learn a lot more

probably how to code your own shaders, since that's one way to have full control

right ?

[vagrant nexus]

I mean, sort of... over some visual aspects, yes

but you dont really have "full control" in unity

its a non-open source game engine

[dawn trench]

yes that's why i switched to unreal for 3d

but its hard for 2d

so I'm using unity for only 2d

[dawn trench]

relatively

[vagrant nexus]

both unreal and unity are 3D engines so

[dawn trench]

but after using for a while i prefer unreal over unity

for 3d

[vagrant nexus]

a lot of 2D features are kind of lacking in unity

but its not impossible to use

[dawn trench]

yeah there is always a way around it

just that few features that should be straight forward

aren't present

well thanks for replying anyways

[late viper]

there's always godot if you really want full control

[dawn trench]

ummm no I'll stick to this enough bouncing around

for now

[dusky wagon]

How would I make my on trigger method only play if certain game object or layer enters the collider?

[marsh quail]

just use an if statement

[lament oasis]

There is no different between OverLapCircleAll and OverLapBoxAll instead of the shape,right?
I mean, they do the samething,right?

[distant pecan]

having the sprite as a child gameobject is by far the best way, but if you want only to flip it, use the spriterenderer.flipx/flipy

[dawn trench]

Yes but I just don't like it so I went with something else

Works all fine

[distant pecan]

basically, the only differences in scripting is that overlapboxall takes a size/angle as parameter while circle takes only radius

[lament oasis]

o hope u can help me ;-;

[distant pecan]

make sure that your gameobject isn't in the fish layer, otherwise it will detect itself in the collider[] array

[bright fjord]

That's probably the case because your Collider isn't the Root GameObject, OverlapBoxAll will give you the Colliders, not the Root GameObject

[distant pecan]

what may be happening in this case is that overlapcircle isn't colliding its own casting object, but overlapbox is

[lament oasis]

as i said, everything i change is the shape to take colider from Circle to Box, nothing else, but it work different like that +_+

[lament oasis]

that why i code enemiestodmg[i].gameObject

it already destroy the fish if i use Circle

but if i use box, the colider destroy itself, dont know why

[dusky wagon]

Oh yeah thats what I could think of but I wasnt sure if there is a better way

[distant pecan]

different shapes, probably one is colliding with the casting object and the other isn't

[lament oasis]

they look like this, the Box, the Circle and the Collider

maybe UnityEngine is bug, cuz i use if to catch just GameObject have tag ca, but it still catch everything on it

[woeful sentinel]

Unity is not a bug.. Unity is a game engine

showing your code may help solving your problem faster

[lament oasis]

I dont talk about Unity, i talk about the libraly UnityEngine

[ebon basin]

Point still stands tho show Ur code lol

[honest python]

my 2D collision detection is not happening every frame

I havew like 1200 fps

and it still kinda moves into other stuff before snapping to the right position

[snow willow]

collision detection is tied to the fixed physics timestep

it is independent of framerate

[honest python]

can I increase that number?

[snow willow]

Project Settings -> Time -> Fixed Timestep

[snow willow]

yes

or decrease it rather 😄

[honest python]

theen will by FixedUpdate time also increase?

[snow willow]

A higher Fixed Timestep means fewer FixedUpdate calls per second.
lower Fixed Timestep means more FixedUpdate calls per second.

Fixed timestep of .02 -> 50 calls per second
Fixed timestep of .01 -> 100 calls per second

etc

[honest python]

I see

[worldly leaf]

howwww

[snow willow]

You have a function inside another function

in this case - OnTriggerEnter2D is inside another one of your functions

which means it is a "local function". And Unity will never call it.

[worldly leaf]

@snow willow function in another function?

[snow willow]

yes

you have something like this

void Update() {
  void OnTriggerEnter2D(Collider2D collision) {
  }
}```
But it is suppsoed to be like this:
```cs
void Update() {
}

void OnTriggerEnter2D(Collider2D collision) {
}```

[worldly leaf]

using System.Collections.Generic;
using UnityEngine;

public class EnemyMove : MonoBehaviour
{
    public int speed;
    public bool MoveRight = true;

 
    void Update()
    {
        if(MoveRight == true)
        {
            transform.Translate(2 * Time.deltaTime * speed, 0, 0);
            transform.localScale = new Vector2(1, 1);
        }
        else
        {
            transform.Translate(-2 * Time.deltaTime * speed, 0, 0);
            transform.localScale = new Vector2(-1, 1);
        }

        void OnTriggerEnter2D(Collider2D collision)
        {
            if (collision.tag == "turn")
            {
                if(MoveRight == true)
                {
                    MoveRight = false;
                }
                else
                {
                    MoveRight = true;
                }
            }
        }

    }
}```

@snow willow its all of code

[hollow crown]

the problem is exactly what they stated it is

[worldly leaf]

but the man in vid can run it with same code

[hollow crown]

The code is not the same

[snow willow]

Please follow the advice to move OnTriggerEnter2D outside of the other function

[worldly leaf]

using System.Collections.Generic;
using UnityEngine;

public class EnemyMove : MonoBehaviour
{
    public int speed;
    public bool MoveRight = true;

 
    void Update()
    {
        if(MoveRight == true)
        {
            transform.Translate(2 * Time.deltaTime * speed, 0, 0);
            transform.localScale = new Vector2(1, 1);
        }
        else
        {
            transform.Translate(-2 * Time.deltaTime * speed, 0, 0);
            transform.localScale = new Vector2(-1, 1);
        }

        
    }

    void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.tag == "turn")
        {
            if (MoveRight == true)
            {
                MoveRight = false;
            }
            else
            {
                MoveRight = true;
            }
        }
    }
}

like this?

[blissful inlet]

I created a grappling gun in my game, based in Camera.ScreenToWorldPoint(Input.mousePosition); and using a Line Renderer, but i want to use a layer mask, to just use the gun in specific layers, but i need a function that tells me if in the mouseposition exists an object, and verify its layer, to see if fits the layer entered

does someone see a solution to this?

[bright fjord]

Camera.ScreenPointToRay

could be the right thing

[pine orchid]

Hi i have a question, am trying to make a leaderboard for my game, i currently have a scoring system for my which saves high scores, i want a leaderboard that stores the top 3 scores.

i tried couple of yt videos but they all show leaderboard for online hosting, i just want an offline one

[vital frost]

having a problem where my character dies from a enemy, but it then crashes the game.
I believe it has to do with this part of the script.
Its either that or I'm just dumb and assigned the wrong things in the wrong places.

[snow willow]

Physics.Raycast for 3D or Physics2D.GetRayIntersection for 2D

[hazy pilot]

Show us the Respawn() function too

[vital frost]

ah right sorry

[late viper]

Could you grab the editor log when it crashes? That would tell you more about the error

[vital frost]

ah ok so I need to reload the player or create a function that calls them back?

[snow willow]

which line of code is throwing the error

[vital frost]

my camera apparently

[snow willow]

Makes sense

your camera is pointing at the player

which is destroyed

So then it doesn't know what to do

right?

[vital frost]

hm yeah makes sense

alright I know how to edit that

[vital frost]

Actually now I'm having trouble doing it
Do I destroy the camera in the same script with the player?
Or destroy it at all?
I'm new to programming sorry about this lol.

[snow willow]

All choices for you 😄

[vital frost]

oh so either

[vital frost]

would it be possible to instead have it focus on the respawn point as the player respawns?

[snow willow]

sure why not

anything is possible

you just have to code it

like - target = spawnPoint; when the player dies.

[vital frost]

aw ok

thanks for the help

would I go into the camera or player death script for that

[burnt badge]

https://paste.ofcode.org/cdt8hYJPyQUh6NW49Df2V8

whenever i run this code, the print reads false

but i dont see how thats possible, since to even get to the print line, the object would have to be in the list, so then why cant it remove it?

[late viper]

do you do anything in enemy.IsOutOfRange that might change that?

[burnt badge]

the out of range function is a simple check to see if the enemy is outside the range of the tower

[subtle vessel]

that code should throw an exception, I think

you're altering the collection inside the loop

[late viper]

oh that makes sense

[burnt badge]

yeah i know right? thats another strange thing

[late viper]

so its not that it's not finding it, its not successfully removing it

[burnt badge]

i see

whats the best way to like, remove items from a list after checking each item?

like, if the enemy is outside the towers range i want to remove it from the list, but obviously using a foreach on the list would throw an error

[subtle vessel]

in this case, you can iterate through the list backward and safely remove the current item

[burnt badge]

that sounds dope af

[late viper]

idk if it'll let you do that

you're still changing the list

[burnt badge]

do you know of another way reo?

[subtle vessel]

for(int i = selectedEnemyList.Count; i > 0; i--) { if(stuff) { selectedEnemyList.RemoveAt(i); } }

you're only changing the parts of the collection taht you've already checked, so it is safe

[late viper]

store references to them in another list remove them outside the loop?

[burnt badge]

implimenting now

[late viper]

you can try both and see what works

[burnt badge]

i thought of that, but that sounds like a pain for something that seems so simple

[subtle vessel]

this works too. It is a more general solution. My solution only works if you're only removing the current element. If you're removing random elements, then you need to copy the list

or you can make a list of items to remove during the loop, then remove them after you've finished looping

also, there are probably some off-by-1 errors in my example above. I think it should be RemoveAt(i - 1);

[burnt badge]

yeah i just got thrown the outofbounds, thats probably why

no, im still getting an outofbounds, gimme a bit while i figure this out

[late viper]

should be int i = selectedEnemyList.Count - 1 first

because you use i in the if check

or you can do i - 1 in the if check, whichever works

[burnt badge]

yeah, i implimented that and it works, it removes the item from the list and no errors

thanks reo and tach, i appreciate the help!

[still tendon]

i need help

@abstract olive i need help

[abstract olive]

Is it a moderation issue?

[still tendon]

i go to put the player content into the add component and it says: "the script don't inherit a native class that can manage a script

@abstract olive

[abstract olive]

Don't tag people unless they're already having a conversation with you. Read #📖┃code-of-conduct if you need a refresher on the rules.

[still tendon]

oh sorry

[arctic cloud]

Hi, is there anyone who knowss how to change the size of the grid in tile pallete?

[hollow rampart]

Sorry if this is more of a question for #⚛️┃physics , I just joined as I am a bit desperate since I don't really know how to search this problem.

So I have a simple setup of using Addforce in the direction of the mouse, works perfectly until I rub against an edge collider, which then skews some of the momentum causing an odd strafe effect.

Black being the force applied
Red the colliders
and Blue being the momentum after bumping into the wall.

Is it that I don't have an axis contrained maybe?

Oh and let me get the script

https://hastebin.com/izecepiseh.cpp

AH, found it out, needed to lock the z-rotation on the Rigidbody

[jolly hawk]

I want to do a mobile game where one tap to screen would perform small part of action and X amount of tapping to screen would perform this task and finish this task. How would I go about this? Any sources how to make this kind of action performance?

[dawn trench]

Bruh tell me a classic snake game where the snake has "bends" isn't "very easy" to code

Whatever I've implemented just looks terrible

[ruby karma]

anything curving is not very easy

[dawn trench]

And it teleports too

So I have to deal with coordinates where the distance between cells isn't one unit

[dawn trench]

Makes sense

I have like three giant if else chains to deal with it

I don't see another way to do it

[runic cipher]

quick question, does tilemap.getTile return the specific tile on the tilemap, or the original tile that the tilemap copy pastes onto every tile?

[dense flame]

I think return the tile that is copy pasted

[runic cipher]

is it possible to get the specific tile?

[dense flame]

I don’t think you can, you need to use the position to change the tile

Tilemap are pretty confusing in this cases

[runic cipher]

how exactly would I do that? I'm using a class built ontop of Tile, I'll refer to it as "newTile". newTile has an array of sprites and based on an Int value called "state" chooses a sprite from the array to display. Is it possible to access and edit the "state" variable in this case?

[subtle vessel]

GetTile returns the instance that is placed, not the prefab. But you'll probably need to call RefreshTile to get it up update after you change it.

[lament oasis]

If i spawn a gameobject inside a colider, can it trigger OnTriggerEnter2D? xD

[dawn trench]

Coordinates are brain damaging

[dawn trench]

wow i feel stupid i wrote 6 complicated lines for a function that only needed one if statement

[restive wedge]

man im doing something wrong. im trying to make a function that switches animator controllers and keeps the current frame (like megaman when he walks normal and then when he shoots during the walk he retains the current frame he was on during the normal walk). i think im stuck on the end...but i dont know how to give the weight or length values to the new clip info, any ideas?

    {
        AnimatorClipInfo[] animationClip = animator.GetCurrentAnimatorClipInfo(0);
        //int currentFrame = (int)(animationClip[0].weight * (animationClip[0].clip.length * animationClip[0].clip.frameRate));
        var currentWeight = animationClip[0].weight;
        var currentLength = animationClip[0].clip.length;
        var currentFrameRate = animationClip[0].clip.frameRate;

        if (isNormalController)
        {
            animator.runtimeAnimatorController = normalController;
        }
        else
        {
            animator.runtimeAnimatorController = normalAttackController;
        }
        AnimatorClipInfo[] newAnimationClip = animator.GetCurrentAnimatorClipInfo(0);
        newAnimationClip[0].weight = currentWeight;
    }```

[compact cave]

Hi everyone! I'm wanting to save a time as a high score in my game and I made a class for the time. I want to save my current time if its less than my current best time, but unity gives me an error for the line where I check this.

[snow willow]

You didn't make a best to start with

so it's null

and you're trying to read null.min

initialize best with some placeholder scores first

best = new GameTime(0, 0, 0);

[compact cave]

Ok thank you ill try that

[snow willow]

also I recommend a function on GameTime that simply returns the time as a single long value in milliseconds. Then it will be extremely easy to compare them with a single if statement rather than a long chain of them

[compact cave]

Thanks so much

It works now

[mild mortar]

hello, i have a 2d setup going on but whenever i add my main avatar, it doesn't appear on the page properly

actually, it doesn't appear at all

the outline of its object is present, but the actual contents within that are empty

[red glacier]

I was wondering how I could make my grappling hook work with moving rigidbodies, can anybody help me?

[mortal ginkgo]

If anyone Knows how to make soft bodies work with bones in unity then please hit me up in my dms so we can talk about it

[mortal ginkgo]

Have you checked that the object in 3D view is not in front of the camera

[subtle vessel]

There are a million different ways to do this. What exactly do you want your grappling hook to do?
If you want most of the work done by Unity rather than writing it all in code, 2D joints might work for you. https://docs.unity3d.com/Manual/Joints2D.html
When the grappling hook hits, attach the objects with a SpringJoint2D maybe and let the join drag your objects together. Just one example of how you might approach it.

[red glacier]

I mean my whole grappling hook works, just doesn't work with rigid bodies. whenever I do it with rigid bodies it connects to where it last was then if it moves the rope doesn't move with it.

if you want to look at the code its all explained and shown in this video: https://youtu.be/dnNCVcVS6uw

Thanks!

[runic cipher]

Hi, I made a BFS search algorithm that uses a distance value as a check. Is it possible to reduce the amount of memory needed? Since I'm using essentially 3 lists in the algorithm. Thanks!

List<Node> getTilesInCircularDistance(Node origin, float distance)
    {
        //find a way to see if it is possible to reduce the number of needed memory

        //BFS search using distance from origin as completion requirement
        Queue<Node> BFSQueue = new Queue<Node>();
        HashSet<Node> discoveredNodes = new HashSet<Node>();
        List<Node> passedNodes = new List<Node>();

        discoveredNodes.Add(origin);
        BFSQueue.Enqueue(origin);
        while(BFSQueue.Count > 0)
        {
            Node currentNode = BFSQueue.Dequeue();
              //getSquareLinearGridDistance returns the squared distance between 2 nodes on the grid
            if(grid.getSquareLinearGridDistance(currentNode, origin) > distance * distance)
            {
                //Node is out of Distance
                continue;
            }
            else
            {
                passedNodes.Add(currentNode);
            }
            foreach (Node neighbour in grid.getGridNeighbours(currentNode))
            {
                if(!discoveredNodes.Contains(neighbour))
                {
                    discoveredNodes.Add(neighbour);
                    BFSQueue.Enqueue(neighbour);
                }    
            }
        }
        return passedNodes;
    }

[snow willow]

Is there any need for the DiscoveredNodes set?

I always do BFS with just two collections: the "fringe" queue, and the "already visited" set

or I gues - is there a need for "passedNodes"?

what is passedNodes doing

Oh it's the results?

[runic cipher]

when I outputed discoveredNodes it included some extra Nodes which I'm not very sure about how they got in there, so I added the passedNodes which just checks if the distance is under the wanted distance.

[snow willow]

here's a BFS I wrote recently:

        public void BreadthFirstTraversal(RadialNode root, Action<RadialNode> visit) {
            Queue<RadialNode> fringe = new Queue<RadialNode>();
            fringe.Enqueue(root);

            while (fringe.Count > 0) {
                RadialNode current = fringe.Dequeue();
                foreach (var child in current) {
                    fringe.Enqueue(child);
                }

                visit(current);
            }
        }```

but this is for a tree

so I don't have an "already visited" list

because trees are one-way

[runic cipher]

if I included a parent-child system for each Node under the getNeighbour function would that let it work in a similar way?

[snow willow]

it's pretty similar to yours so maybe you have an issue with your getGridNeighbours function?

[runic cipher]

the getGridNeighbours function just returns a reference to the 8 nodes that surround the argument Node

Actually I think I might have a solution here let me try something.

[snow willow]

oh

I think... maybe it's better to do the discoveredNodes check when you are visiting a node (first thing in the while loop) instead of doing the check as you decide whether to add the neighbor to the queue or not?

[runic cipher]

the discoveredNodes is meant to keep track of which ones are already added, so that I don't check a node twice. Would that logic still apply with that solution?

Also my attempted solution froze the game and outputted 30 errors per second. Sounds about par for the course, heh

[subtle vessel]

are you just trying to get all nodes within a certain radius of the center?

[runic cipher]

yes

[subtle vessel]

a hacky solution that I've used before is to just loop over a square and check whether each node is within the distance

[runic cipher]

An issue with that is that I plan to use this in a "tactics style" game, like XCOM or Wargroove, where the environment can have an effect on the traversable nodes, if I used that method then it would be harder to implement the environmental effects.

Thanks for the suggestion, though. I think I can find use cases for that method.

[subtle vessel]

mmm, so you're essentially looking for Dijkstra's out to a certain radius

[runic cipher]

isn't BFS and Dijkstra for different use cases?

[snow willow]

Dijkstra is pretty much BFS but with keeping track of travel distance to each node as you traverse the graph

[subtle vessel]

yeah, I guess. I think of Dijkstra's as A* without directionality to it, but I guess there is the sorting of path lengths too

[snow willow]

yeah - and A* is just Djisktra's with a physical heuristic to guess which way to search first 😛

they're all part of the same family

[runic cipher]

Forgive me but I still don't understand how Dijkstra will work in this case, isn't it meant to search out to a target Node instead of exploring all possible Nodes?

[snow willow]

dijkstra is a flood fill algorithm that stops when it accidentally runs into the target node

all you do is change the conditions for stopping

instead of stopping when you hit some target, you stop when you can't find any more nodes that are within your movement budget

[hazy pilot]

Not to ask the obvious question, @runic cipher , but would a non-BFS search be better? IE - just checking every node in your system and adding them to a "found nodes" list if they're within distance^2 (or whatever your logic is there) ? Or are there too many potential candidate nodes

[runic cipher]

I see, do you have a piece of documentation I can refer to?

[snow willow]

I wouldn't be pointing you to anything except the google result for dijkstra's algoirthm.

Most of what I know I remember from college

[hazy pilot]

if (thisNode.distanceFromOrigin < maxDistance) foundNodes.Add(thisNode); etc

[runic cipher]

I want to keep the system modular so that it can scale regardless of the map size, but I expect the maps to be about ~50x50 at maximum. I just followed BFS since it seemed logical.

[hazy pilot]

oh if they're 50x50 i wouldn't worry about performance or memory, tbh

I mean as long as you're not doing something too boneheaded like searching for those nodes every update() call 🙂

[runic cipher]

that was definitely not what I tried first I swear

[hazy pilot]

sometimes the easiest-to-program solution is the best one, until you run into problems, then you optimize those functions

[snow willow]

If you look at the pseudocode for it here, what it actually ends up doing is finding the shortst distance and path to every node on the map. And they add a little note at the bottom for "if you only want a shortest path to a certain target, you can terminate the search after line 15"
https://en.wikipedia.org/wiki/Dijkstra's_algorithm#Pseudocode

[hazy pilot]

i think in general it is worth keeping your update() calls minimal, and even if you need to figure out this set of nodes "often" you could at least do it every second or less and it would probably still be invisible to the user

[snow willow]

although the entry under that for "using a priority queue" is the more efficient method

[hazy pilot]

i like keeping my renderer classes with the update() commented out entirely

    /* %%%%%%%%%%%%%%%%%%%%%%%%%%%%%% UNITY FUNCTIONS %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% */
    #region UNITY FUNCTIONS
    private void Awake() 
    {
        LocalAssert();
        Player.OnPlayerUpdated += UpdateScreen;
    }
    private void Start() 
    {
        UpdateScreen();
    }
    //public void Init() {}
    //private void Update() {}
    private void OnDestroy() 
    {
        Player.OnPlayerUpdated -= UpdateScreen;
    }

my typical "render" screens

actually better example

so the screen only "does work" when it needs to

not exactly the same as your problem but transferable concept - you would only update your list of nodes-of-interest when you need to.. perhaps every 5-10 seconds, or every time someone traverses a node, or whatever makes sense for your application

(and you can always work on optimizing FindNodes() or whatever when you're tired of working on real work) 🙂

[runic cipher]

I see, I guess I still have a lot to learn regarding programming hehe

[hazy pilot]

don't we all

i think honestly .. don't worry about optimizations until you have FPS or out-of-memory errors

[runic cipher]

Thanks for all your help everyone! I really appreciate it ⊂( ´ ▽ ` )⊃

[hazy pilot]

you might spend a whole bunch of time optimizing your code and then finding out that it runs in 0.001 sec anyway

[runic cipher]

The problem with this is I do not want to look at my old code for fear of death induced by disappointment, so I prefer to try and make it as efficient as possible from when I first code it

[hazy pilot]

hehe

[snow willow]

honestly djikstra's isn't that hard but I might be biased having literally learned it in school

[hazy pilot]

little tip... you will 🤮 when you look at your own old code no matter how hard you try

[snow willow]

so ymmv ¯_(ツ)_/¯

[hazy pilot]

i have a little bucket next to my desk specifically for that reason

[subtle vessel]

I gotta get me one of those

[runic cipher]

I don't have a bucket but I have a cup of milk tea that I drink whenever I feel grossed out by my code

the sugar helps dampen the disappointment

[snow willow]

yum

[runic cipher]

It also serves as a good indicator for when I need to take a different perspective to the code. If half the cup is empty within 10 minutes then I know something is definitely wrong, although my weighting scale doesn't really think this is an optimal solution

[fallen flicker]

Yes but looking at old code can be a good thing because you get to see how far you've come 😉

[hybrid bane]

hello, so i've been having an issue for a few months now, but i haven't figured it out or received any help yet. if anybody knows what is causing this, i would greatly appreciate help. the problem is that whenever i go into the skinning editor to rig my character, it shows up with these boxes around the sprites. when i try to draw bones onto it, i have to double click a box first and then can only draw bones onto that one section of the sprite.

this isnt how it works in any of the tutorials i have watched, and despite me importing all the needed packages, i still seem to have this issue. please help

Hello it's me again, not sure if it's a coding or more of visualisation question, but it's regarding my previous question. my previous example used BFS to get Nodes within a certain distance from an origin Node, this instance used the pure euclidean distance from a tested Node to the origin Node to see if it's out of range. In this scenario(using pure euclidean distance), is it impossible to use a movement penalty system in the calculations? Since movement penalties in algorithms like this take the form of a "cost" calculated as a Node is checked as a child of another node, which is not shown when taking pure euclidean distance between 2 Nodes.

Nevermind, I just answered my own question.

[still tendon]

how do i make my bullet move in the direction it's facing?

[turbid heart]

since this is #🖼️┃2d-tools , is your bullet going left and right?

[still tendon]

yes

[turbid heart]

I'm not sure.. how are you flipping your bullet at the moment?

[still tendon]

Instantiate(bullet, shotPoint.position, transform.rotation);

[turbid heart]

okay, where do you decide whether it's facing left or right?

[still tendon]

in my character controller

[still tendon]

in my character controller ```cs
private void Flip() {
// Switch the way the player is labelled as facing.
m_FacingRight = !m_FacingRight;

    if (m_FacingRight == true) {
        transform.rotation = Quaternion.Euler(0, 0, 0);
    } else{
        transform.rotation = Quaternion.Euler(0, 180, 0);
    }
}

[turbid heart]

okay, I guess you can create a isFacingRight boolean for your Bullet, and set it when your player fires a bullet? @still tendon

[still tendon]

okay i'll try that

[still tendon]

i've found an inefficient but working solution
2 prefabs both going in different directions, if the gun script is facing right, then i instantiate the right prefab, otherwise the left prefab

[subtle vessel]

You can set the x-scale to -1 or rotate it by 180 degrees around the y or z axis.

Enemy is patrolling but i want to if enemy will turn, enemy will wait for seconds, after than he will turn and go. Any idea?

[turbid heart]

does it not work now?

do you have any errors? I'm not sure, but it looks like your visual studio isn't set up properly yet

[topaz dawn]

You mean the collider?

[wide ginkgo]

Can you show source image?

[turbid heart]

it can be png

[wide ginkgo]

PSD is fine, can you screenshot it when it's open in PS?

Yeah understandable. Easiest fix would be to trim the image and remove all empty space. But it might be worth to show you how to fix it in Unity as well.

So in Photoshop you'd just Image -> Trim.

[worldly leaf]

enemy is patrolling but no waiting

no errors

[wide ginkgo]

In Unity you'd select your sprite asset. Then click Sprite Editor. In the editor you can drag the edges to make it smaller. Then click Apply in top right.

@still tendon Sorry I completely mixed two things up. If you actually want a smaller sprite you first have to select your Sprite asset. Then make sure Sprite Mode is Multiple. Open the sprite editor, drag a box around your sprite, and hit Apply.

When you've done that you should now have a separate sprite in your sprite asset, use that one. Just click the arrow next to it.

[turbid heart]

can you try to put all the code that's after StartCoroutine into, the Wait Coroutine itself

[worldly leaf]

@turbid heart i fixed it thanks

[livid walrus]

Hey guys i have a problem, I am trying to create a 2d labyrinth game but i dont know how to fit my game to multiple screen sizes. Thanks for your help in advance

[radiant wigeon]

Do I add a physics material to the player sprite, the ground sprite, or both?

[snow willow]

Up to you

[radiant wigeon]

ok

[mortal ginkgo]

does anyone knows why this is happening and a way to solve it

(the two collisions are inside of eachother and you can not move when this is happening), both are not triggers

[snow willow]

which two objects

the brown thing and the red thing?

[mortal ginkgo]

no the colision on the light brown thing and the bowl/brown thing

[radiant wigeon]

Im trying to make it when the player touches a block something happens

I have this code:

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

public class Player : MonoBehaviour {

    float horizonalMovment;
    Rigidbody2D rigidBody;

    void Start() {
        rigidBody = GetComponent<Rigidbody2D>();
    }

    void Update() {
        horizonalMovment = Input.GetAxis("Horizontal");
    }

    void FixedUpdate() {
        rigidBody.velocity = new Vector2(horizonalMovment * 5f, rigidBody.velocity.y);

        if (Input.GetButton("Jump")) {
            rigidBody.velocity = new Vector2(rigidBody.velocity.x, 8f);
        }
    }

    void OnTriggerEnter(Collider other) {
        if (other.gameObject.layer == 6) {
            Debug.Log("test");
        }
    }
}

But nothing happens when I touch the block, I just go through it

[knotty barn]

Is the Trigger called at all? Where is the trigger collider, on the player object?

[snow willow]

• Do both objects have 3D Colliders?
• Does at least one collider has "IS Trigger" checked?
• Does at least one object have a 3D Rigidbody?

[radiant wigeon]

it 2d

[snow willow]

Also put a log statement to check if it's runnin:

    void OnTriggerEnter(Collider other) {
        Debug.Log("running!");
        if (other.gameObject.layer == 6) {
            Debug.Log("test");
        }
    }

[snow willow]

you are using the 3D callback function

use the 2D one

void OnTriggerEnter2D(Collider2D other)

[radiant wigeon]

ok

It works but now how would I make it set the player back to the level start?

[dusky wagon]

Is there a way to merge a box and a circle collider into one collider? I had som issues with or being two because sometimes for example a coin counted as two, when both colliders hit it at the same time. I tried making it an edge collider, but it cause even more issues. For example when landing while moving you get teleported a bit

[silk sorrel]

Is it possible to render a tilemap twice, slightly modifying it?

Eg to make the shadow like in the picture

When I rotate the sprite 180 deg is becomes invisible

How to correct it

[blissful inlet]

Set Y to 0 and try rotating in Z to 180

I made sprite of a wire (2D), and now im trying to make this sprite look like a real wire, that connects to my character and moves with it and drag across the floor, someone knows?

[knotty barn]

@slim scaffold Don't crosspost.

[lime widget]

quick question. I wrote a coroutine that implements a jump by modifying the Z dimension of my character using transform.position. I also have X and Y movement done through rigidbody.MovePosition. for some reason, I can't seem to move my character in the X/Y dimensions while the character is jumping. input is still working, as I can Debug.Log the vector that the input is generating, and it's printing out values as expected. any ideas?

[turbid heart]

Please show your movement and jump code

[lime widget]

    private IEnumerator Jump() {
        float last_height = transform.localPosition.z;
        float max_jump_height = last_height + jump_height;
        while (transform.localPosition.z + (vert_speed * Time.fixedDeltaTime) > max_jump_height) {
            transform.Translate(new Vector3(0, 0, vert_speed * Time.fixedDeltaTime));
            yield return null;
        }
        transform.position = new Vector3(transform.position.x, transform.position.y, max_jump_height);
        jumping = false;
        yield break;
    }

    public void OnMove(InputAction.CallbackContext context)
    {
        direction = (Vector3)context.ReadValue<Vector2>();
    }

    void LateralMovementHandler() {
        rigidbody.MovePosition(((direction * speed * Time.fixedDeltaTime) + transform.position));
        sprite.transform.position = rigidbody.transform.position;
    }

OnMove is a callback that gets triggered by the Move callback context defined in the Input Action asset

LateralMovementHandler is called in FixedUpdate()

    public void OnJump(InputAction.CallbackContext context)
    {
        if (!jumping && grounded) {
            jumping = true;
            grounded = false;
            StartCoroutine("Jump");
        }
    }

[turbid heart]

I don’t know how to help because that’s a bit more complex than expected, but hopefully someone else can

[lime widget]

👌 no problem

I'm wondering if maybe unity doesn't like it when I call transform.Translate and rigidbody.MovePosition in the same update

[turbid heart]

That sounds plausible

[lime widget]

huh. after changing the rigidbody.MovePosition to transform.Translate it works

🤔

That's annoying since I need collision detection on lateral movement but not vertical movement

Wonder why that's happening...

[snow willow]

they're two completely incompatible movement strategies

transform.Translate just teleports the object directly and bypasses the physics engine entirely

[lime widget]

Yeah I know, that's why I'm using it

How does Unity know which one to "do"?

[snow willow]

wdym

[lime widget]

As in, why does it do the Translate, but not the MovePosition

Why not the other way around?

Or is it UB?

[snow willow]

translate is going to just overwrite anything the rigidbody is doing basically

so it doesn't matter if the RB moves somewhere because the Transform is getting teleported

also MovePosition doesn't happen until the next physics update happens

From your code snippets it's unclear where you're calling it

[lime widget]

Ah I see. Does it get tossed into some sort of queue?

I'm calling it from within FixedUpdate

[snow willow]

not a queue

[lime widget]

    void LateralMovementHandler() {
        transform.Translate(direction * speed * Time.fixedDeltaTime);
        // rigidbody.MovePosition(((direction * speed * Time.fixedDeltaTime) + transform.position));
        sprite.transform.position = rigidbody.transform.position;
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        LateralMovementHandler();
        CheckGrounded();
    }

[snow willow]

if you call MovePosition twice between physics updates, it just uses the most recent position you called it with

it overwrites

[lime widget]

ah I would think it would aggregate

[snow willow]

it does not

[lime widget]

I see. Is it the same case with transform.Translate?

As in, if I have two translates it uses the "last"one

[snow willow]

no

translate happens immediately

[lime widget]

hmm, so would it work if I did translate and then rb.MovePosition?

I'm assuming Coroutines are evaluated after everything else in the script is, which is why I'm not seeing the rb.MovePosition

[ebon galleon]

Anyone know much about IK Managers? Mine seems to work fine when animating but when running the game the sprite legs (the bones I used the IK Manager on and other parts, but both being LimbSolver2D and FabrikSolver2D) are just acting like moving sticks instead of bendable legs. Bones themselves seem to work fine though.
Please if anyone has any suggestions I'm more than happy to try them

[vital frost]

I wanna make my camera snap to the respawn point after you die and then snap back to the player
how would I go about that?

[ebon galleon]

I know shit all but you could just try setting the camera.transform in the camera script to the point of respawn if it grabs a death = true or something from the player script. Idk for certain, but you could have a crack at that while waiting for someone to answer it

[vital frost]

hm k ill mess around with it

[vital frost]

Yeah idk what the hell im doing lol

I dont know how I would go about this still or what functions I would need to use

[still tendon]

Alright folks I have a problem with the linerenderer not showing up on top of the scene

This is playmode
