you need to copy the texture's contents (or make two render textures)

[languid spire]

isn't there a texture = new Texture(renderTexture); to make a shallow copy?

[swift crag]

That sounds plausible to me, yes

[rich adder]

yeah this reference type

its same texture

[swift crag]

This is one area where I don't have much experience, alas.

[queen adder]

Trying to sort a list but i think im doing it wrong somehow?

[swift crag]

I played with RTs in a game jam once where I spent most of the jam creating a procedural level generator instead of making the game fun

whoops

[rich adder]

iirc you need to copy it by using the GPU method built in
https://docs.unity3d.com/ScriptReference/Graphics.CopyTexture.html

[swift crag]

random guess: you're using LINQ's OrderBy method, which doesn't do anything to the list

but if that hard read was wrong, context please!

[queen adder]

Im about to copy and paste the code give me one second

But yes ur right

Using OrderBy

[languid spire]

you didn't read the docs then did you

[swift crag]

That produces a new IEnumerable<T>, as do all LINQ methods.

consult the docs for List<T>

you will find what you need

[rich adder]

reading docs is overrated. /s

[languid spire]

heretic

[queen adder]

{
    _current_index = 0;

    PlayerPawns = FindObjectsByType<PlayerPawnBase>( sortMode: FindObjectsSortMode.None ).ToList();

    PlayerPawns.OrderBy(pawns => pawns.BattlePawn_SO.SpeedOrder ).ToList();

    for(int i = 0; i < PlayerPawns.Count; i++)
    {
        print($"{PlayerPawns[i].BattlePawn_SO.CharacterName}");
    }
}```

[swift crag]

you order the enumerable, create a list, and then...throw the list away

[queen adder]

Oh really

[swift crag]

yes really

[queen adder]

I didnt realize

[swift crag]

AddTwoNumbers(3, 5);

it's like you did this

the answer is 8. but you do nothing with the answer, nothing happens

[oblique ginkgo]

line 7 sorts the list PlayerPawns, returns a sorted ienumerable, converts it into a list, then just throws it away without doing anything with it

[queen adder]

So im not returning it correctly?

[swift crag]

you seem confused

[languid spire]

your not returning it at all

[queen adder]

I am lmao

[swift crag]

look at the methods you're calling instead of just hoping they do what you think they do

https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.orderby?view=net-8.0

OrderBy takes an enumerable and produces a new enumerable.

https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.tolist?view=net-8.0

[queen adder]

I see

[swift crag]

ToList takes an enumerable and returns a list containing the enumerable's elements.

[queen adder]

Makes sense

[swift crag]

now, you COULD write this:

PlayerPawns = PlayerPawns.OrderBy(...).ToList();

This would be a valid program, and it would do what you want it do (make PlayerPawns be a sorted list)

[queen adder]

Yeah^^

[swift crag]

however, this means that you're throwing out the old list and replacing it with a new one.

this does not sort the list referred to by PlayerPawns

it stores a new list into that variable.

on the other hand...

https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.sort?view=net-8.0

[queen adder]

I see simple mistake on my part

[swift crag]

You should not be using OrderBy...ToList at all here.

There's no point. Just call Sort.

[languid spire]

and generates shit loads of garbage to boot

[swift crag]

indeed

Now, there is one downside to List<T>.Sort

[queen adder]

Which is ?

[swift crag]

It's more awkward to use a custom comparison function.

oh wait, no it's not

https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.sort?view=net-8.0#system-collections-generic-list-1-sort(system-comparison((-0)))

very nice

[robust kelp]

i did this and for some reason the movement is laggy, velocity isnt clamped exactly to its max speed it just changes really fast from 20 something below maxspeed to 20 something above

[swift crag]

Comparison<T> is a delegate type

[swift crag]

you just need to write a method that compares two PlayerPawnBase objects

[queen adder]

I get it now

[swift crag]

rather than a method that turns a PlayerPawnBase into a comparable value.

[queen adder]

It was a really simple mistake

Thank u for ur guys help 🙂

[swift crag]

don't you want to clamp the XZ velocity?

[robust kelp]

yea

[swift crag]

then just clamp that and be done with it

your code is clamping the XZ and Y velocities whenever the total velocity gets too high

that's going to be very unusual looking

[silver sun]

whats wrong with this code?wehn i run it the movement is inverted so when i press w it goes left if i press s it goes forward or backwords

https://gdl.space/ucuxucayub.cpp

who is blud talkin too

[swift crag]

perhaps your model/sprite/etc. is oriented wrongly

click on the object that NewBehaviourScript is attached to

[stable ore]

how to change?

[stable ore]

alr

[swift crag]

make sure your scene view is in local + pivot mode

The blue arrow you see is forwards.

[silver sun]

you made it look like you were pointing out my code sharing method

[swift crag]

e.g.

[stable ore]

alr is

[swift crag]

If the blue arrow doesn't point in the direction you think should be forward, then you need to adjust something.

[stable ore]

no i was tryna do get the links to import code for myself

[swift crag]

indeed, you're off by 90 degrees

[stable ore]

yh

how do i change?

[swift crag]

here's my suggestion

[stable ore]

is it in blender i gotta change

[swift crag]

parent this model prefab to a new empty object

[rich adder]

Blender

[swift crag]

Then you can just rotate the model however you need to.

You could also fix it in Blender, yes

[stable ore]

i can just do it in blender and re export ittl be easier

[swift crag]

Also, I see that you have a rigidbody on the model.

since you do, you should not be using transform.Translate

you should be moving the rigidbody itself

[swift crag]

Even if you do, it's still a good idea to parent the model to an empty object. That makes it easy to adjust the exact position, to swap it out, etc.

[stable ore]

what would the code look like?

[rich adder]

doing it in Unity is faster though , and you need to separate ur mesh from main object anyway

[swift crag]

https://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

Note that this works in world space, not local space

unlike transform.Translate

Just use transform.forward instead of Vector3.forward and it'll work out nicely

[rich adder]

always keep mesh as child, this way rotations/scale is incosequential to main object with logic/colliders

[swift crag]

transform.forward is the direction the transform is pointing in world-space

[stable ore]

i have

and what do i do next

[swift crag]

rotate the model so that it lines up with the parent object's forward direction

so, when you have the parent selected, its blue arrow should match where the model is facing

[stable ore]

like this?

@swift crag

[swift crag]

You've parented it to a cube. I said to parent it to an empty object.

[stable ore]

oh

alright

[swift crag]

So just delete the box collider, mesh renderer, and mesh filter from the cube

that'll give you an empty game object

you'll also need to move the movement component onto the root object

[sullen zealot]

hello!
is there a way to have a function executed only for the first 25 frames?

[rocky canyon]

sure.. count frames

[rich adder]

yes

[swift crag]

sure, add a condition that checks if Time.frameCount < 25. But what are you really trying to accomplish here?

[rocky canyon]

^ ding ding ding

[tender wren]

I am having an issue using a variable created on an object in editor.

Object1(EmptyObject) has moduleBuilder:

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

[ExecuteAlways]
public class ModuleBuilder : MonoBehaviour
{
    public static ModuleBuilder mb;
    public List<Module> modulelist;

    private void OnGUI()
    {
        if (mb == null)
        {
            mb = this;
        } else if (mb != this)
        {
            Destroy(gameObject);
        }
    }
}

Object 2 is trying to access Object1's static property:

        }
        bool addme = true;

        foreach (Module m in ModuleBuilder.mb.modulelist)
        {
            if(m.GetHashCode() == this.GetHashCode())
            {
                addme = false;
            }
        }
        if (addme == true)
        {
            ModuleBuilder.mb.modulelist.Add(this);
            print(ModuleBuilder.mb.modulelist.Count);
        }

getting this error and a nullreferenceerror:

Objects are trying to be loaded during a domain backup. This is not allowed as it will lead to undefined behaviour!

What am I doing wrong logically here?

[rocky canyon]

but yea, thers probably a better solution

[sullen zealot]

in update?

[rocky canyon]

ud have to check if every frame to be accurate

so yes..

[stable ore]

like this yh?

[swift crag]

What are you trying to make your game do here?

not "do something for the first 25 frames"

[stable ore]

its till doing the incorrect movement

[swift crag]

well, yes, you haven't moved the movement component yet

[rocky canyon]

thats just an optimization (better way to do it)

[swift crag]

it's still attached to the model

Put the movement component on the root object.

[rocky canyon]

yup, move the main parent.. the graphics will follow along b/c of them being child objects

[swift crag]

you've managed to avoid screenshotting anything useful here

select the root object and show us the inspector

[sullen zealot]

i want to save the renderTexture to a sprite thorugh a function, but i have 25 sprites and if i do a for loop in start function it makes all sprites the same bc the render camera doesnt update until the next frame

[stable ore]

here

i attatched the script to the empty

and it still has incorrect movement

[rocky canyon]

u can use a coroutine..

and wait until next frame

[swift crag]

remove the rigidbody from the model.

[sullen zealot]

yea but how do i stop?

[swift crag]

you should stop after you've gotten to the last sprite

this sounds like a simple for loop to me

[rocky canyon]

yup

[sullen zealot]

oh yeaa

ahahaha

thx

[rocky canyon]

       foreach (var item in yourArray)
        {
            // Perform actions on the current item

            // Wait for one frame
            yield return null;
        }```

[stable ore]

it works @swift crag

LESS GOO

[rocky canyon]

 private IEnumerator DoActionsWithDelay()
{```

[swift crag]

if you want to have a rigidbody, then put it on the root object and control its velocity or position

[rocky canyon]

ofc ud need to put it in a coroutine to use the yield return

[stable ore]

now i gotta figure out why i shouldnt use transform.translate

[rocky canyon]

you can

no ones stopping you..

its basically just teleporting

[stable ore]

oh

[swift crag]

If you have interpolation enabled, setting the transform's position won't work.

The rigidbody will overwrite it.

[rocky canyon]

ahhh true true

rb.MovePosition

is a good one

[swift crag]

MovePosition() tries to respect colliders as it moves, yes

[rocky canyon]

   // Move the Rigidbody using MovePosition
        rb.MovePosition(rb.position + movement * moveSpeed * Time.deltaTime);```

[stable ore]

i can tell @rocky canyon is about to loose his braincells

from me

[rocky canyon]

you should only call (1) of those methods not two.. just add the vectors and stuff into a variable together

and only call the rb.MovePos. once..

[rich adder]

why not just use character controller

also moving RB in update is wrong

[stable ore]

https://gdl.space/iquzuruleq.cpp

would this be right?

[rocky canyon]

The Rigidbody.MovePosition method is typically used within the FixedUpdate method for physics-related operations. However, Unity automatically interpolates the movement when you call MovePosition in Update, ensuring smooth motion.

i think you could use it from update..

[rich adder]

interesting..

[rocky canyon]

but yea generally bad. esp if ur setting its velocity directly.. like rb.velocity = thats def reserved for FixedUpdate

[rich adder]

I haven't used MovePosition much so I was under the impression it was same as .vel or AddForce acceleration

[rocky canyon]

its b/c it runs in fixedupdate anyway.. even if ur calling from update.. it probably takes the last one that was called b4 the fixedupdate kicks in

but im unsure exactly.. but i know that u can get away with it.. altho probably not very proper

[rich adder]

yeah but so is addforce

[rocky canyon]

yea.. thats another one you CAN use in update..

but i wouldnt anyway

yea but anyway.. he's right..

commonly keep ur rigidbody stuff in fixedupdate

[stable ore]

what should i use then?

[rocky canyon]

• get input from update
• act on that input in fixedupdate

[rich adder]

I just know it from everyone preaching it like gospel lol

[stable ore]

for my movement thats the best

[rocky canyon]

what type of game are you making?

[stable ore]

im new so i wannna just make something to practise but i would love to create mobile games in future

[rich adder]

for simple movements I just usually go with CC

[rocky canyon]

tbh CC is perfect for basic stuff..

it has built in stuff where it can walk up slopes and stairs..

and can handle basic verticallity like jumps and whatnot

[rich adder]

Yeah, the only issue is going down the slops it skips but that can be fixed with getting slope normals (bit advanced topic)

[stable ore]

is that the best for mobile games?

[rocky canyon]

Rigidbody is more powerful and more natural

[rich adder]

the genre/platform is inconsequential

[rocky canyon]

CC is easier and better for beginners to pick up on

[stable ore]

alr ill use that then thanks

[rocky canyon]

you can use CC in update.. u wouldnt need to worry about splitting up ur inputs and movements

[stable ore]

and that stands for character controller right

[rocky canyon]

yessir.. you dont need a rigidbody if you go that route

[stable ore]

isnt rigid body built in physics like gravity

[rocky canyon]

look up Simple / Basic Character Controller for some tutorials

[stable ore]

why wont i need it?

[rocky canyon]

they're all about the same thing

[stable ore]

going to tmr

[rocky canyon]

b/c CC uses a capsule collider and a CharacterController component

[stable ore]

gonna go work on my blender project

[rocky canyon]

it does math internally to get smooth movements and stuff

[stable ore]

alr

[swift crag]

character controllers can be reliably moved in Update and make it easy to move around and over colliders

[rocky canyon]

^ as a beginner ur probably best to use the CC and work ur way up to a rigidbody

[ivory bobcat]

Physics consists of more than just gravity but yes. You'll get the entire behavior - many unwantedly unless you're making a physics simulator.

[rich adder]

only thing with CC is you need to make your own Gravity but Unity has an example script

[stable ore]

does CC have built in gravity like if im making a game twhere you skii would the gravity work?

without rigid body

[rich adder]

also you can just use the new CC starter assets.
but learning the basics on how it works it probably benefit your learning

[rocky canyon]

you will have to code in gravity yourself for the CC but thast basic..

you just can add a negative vector to ur variable b4 u use it in the CC move functions

[stable ore]

idk what that is but will look into that

sounds intresting

[ivory bobcat]

The example from the docs illustrate moving, jumping and gravity: https://docs.unity3d.com/ScriptReference/CharacterController.Move.html

[scarlet skiff]

Jump animation wont play
https://paste.mod.gg/vivijqehsxey/0
The code ^^

[rocky canyon]

    private void Update()
    {
        // Example: Move the Character Controller with gravity
        float moveInput = Input.GetAxis("Horizontal");
        Vector3 movement = new Vector3(moveInput, 0f, 0f);
        movement.Normalize();

        // Check if the character is grounded (you might have your own ground check logic)
        bool isGrounded = characterController.isGrounded;

        if (isGrounded)
        {
            // Reset velocity when grounded
            velocity.y = 0f;
        }
        else
        {
            // Apply gravity when not grounded
            velocity.y -= gravity * Time.deltaTime;
        }

        // Move the character using CharacterController.Move
        characterController.Move((movement * moveSpeed + velocity) * Time.deltaTime);
    }```
boilerplate example

has built in ground checking

[rich adder]

the only cringe unity put there though, 2 movecalls instead of 1 even they themselves recommend calling it just 1 once lol

[swift crag]

yes, that can cause problems with detecting grounding properly

[rich adder]

literally they could've just put a + lol

[stable ore]

doesent && grounded do that job?

[rocky canyon]

oohh gross, lmao nice catch

[swift crag]

isGrounded reflects the most recent movement. If you didn't move down at all, and you're on flat ground, you won't wind up with isGrounded being true

since you just moved horizontally over the ground without bumping into it

[swift crag]

I don't know what you mean.

Exactly! xD

make it a Github thing

so many docs link to github (I think the new docs they did that) Netcode

[ivory bobcat]

Beginner coding help with Unity. Non coding stuff would go in #💻┃unity-talk or an appropriate channel #🔎┃find-a-channel

[rocky canyon]

well && just means AND in a conditional...
if (x > 0 && y > 0) or

{
    if (y > 0)
    {```
its just how the code is written, u could use a ground check with it and w/o it.. by using two if statements.. not really relevant to whether its a CC or RB but,
- a rigidbody doesn't have a built in ground check (you have to program it yourself)
- a cc does have one already

theres pro's and con's to each.. but CC is the fastest to get up and running a basic character for sure ⭐

[stable ore]

ill defo watch a couple vids and read about it but rn just gonna chill and work on my blender project

[rocky canyon]

👍 good luck

ahhh beat me

[rich adder]

you got both which is prob better 🙂

[rocky canyon]

well the quicker u get the bones set up the faster u can build / modify it to be a good system

[stable ore]

roblox movement used raw axis and it dosent feel nice

[rich adder]

is roblox fpv or third

[stable ore]

or look

[rich adder]

idk even know

[stable ore]

any

[rocky canyon]

don't discount us saying quicker as half assed

cuz not the same thing

[rich adder]

i assure you with a few tweaks in inspector those character premade controllers feel pretty good

you just need to tweak them enough

[rocky canyon]

stock sucks

[rich adder]

yeah their gravity is a bit light for my taste

feels "floaty" (but then again its video games not realism xD)

[stable ore]

yh i will test it

[rocky canyon]

oh for sure.. thats a must for me.. first thing i do is go to my project and bump gravity up between -10 and -12

and drop my physics tick to be 60fps

[rich adder]

I use -20ish lol

[rocky canyon]

thats totally fine too 😄

[rich adder]

Jupiter gravity

[rocky canyon]

a bit realistic for me

all my projects prefix arcade- to the front lol

gives me an escape window..

[rich adder]

yeah I've been making just "insert activity" sims

[rocky canyon]

"well, its arcade, it isnt supposed to feel real"

[rich adder]

so jumping is kinda not really priority

[rocky canyon]

i made a joke a while ago about moving the ground downwards for a jump..
it actually works.. probably hella unperformant if i were to continue with it LoL

you have it configured for C# but not game development with unity

you could use instead Debug.Log(playerName + " was attacked by a wild " + animalName);

but nothing wrong with string interpolation, its even nicer when you have lots of variables to print out

still having the faux hitbox issue - I found if I move the box it thinks it is colliding with back, the raycast extends a little bit farther. It's as if the hitbox for the wall is on the left room instead of the right room

[meager raptor]

Ah okay thanks

[sleek radish]

Preserving player's local y velocity correctly

[edgy fox]

(the raycasts extend from the center of the room to where out RaycastHit hit says it hit hit.point)

[sly wasp]

https://pastebin.com/wPAVLDst I got a script here that controls blendshapes, it works but is very annoying to constantly edit the strings of the blendshape name. Is there a way to get the component of the first second and then third blend shape? Kinda like m_Animator?

[edgy fox]

so it's literally as if the walls on the rightare actually around the room on the left

[rocky canyon]

i would start considering using a different scene.. and testing the thing a little by little..
maybe rebuilding ur pieces and trying..

idk, i watched in yesterday with this issue and im with Vertx, im stumped as to what could be happening..
at a certain point (when i have issues i can't solve) i try to start over or isolate the problem pieces to just theirselves.. to eleminate any possibility other things are messing it up..

try getting it working w/ the most basic of setups... and if that doesn't work then you can atleast rule out it being a bug in the project or something unexplainable..

but idk /shrug tbh

[edgy fox]

alright - what's most confusing is that when I click the pingable debug log it doesn't highlight the object the raycasat thinks its hitting

but it def is that object because if I mess with WallEZ's hitboxes it affects the drawn ray

I guess I'll just try and reconstruct it

see if I can replicate this bug

[swift crag]

Do you happpen to be using hit.transform or hit.rigidbody by any chance

[edgy fox]

hit.transform.gameObject

and the scene has no rigidbodie

[swift crag]

That'll do it.

ah, no rigidbodies?

[edgy fox]

not a single one

[swift crag]

hit.transform can give you a parent transform if it hits a collider under a rigidbody

[real merlin]

quick question can i store function in an array

sorry if it's really dumb

[rocky canyon]

^ thats screwed me up sooo many times

[swift crag]

sure, System.Action[]

or probably a List<System.Action>

if you want a list

[edgy fox]

wait wym

[swift crag]

if the function has arguments or retuens something that isn't void, you need a different type

[edgy fox]

well I have no rigidbodies so that shouldn't be an issue

I get what you mean nowthough

brain's just running a tad slow today

[swift crag]

Show me your code (or link me to it again)

[sly wasp]

Sorry for asking again, may I have help with this please?

[real merlin]

no it doesn't have arguments and it doesn't return anything, it just modifies variables in other gameobjects

[swift crag]

okay, then that'll fit into a System.Action variable

[rocky canyon]

he means sometimes ur raycast can hit an object down the hiearchy
but the raycast will return the root

it's pretty long

see here

[rocky canyon]

chunkers

[edgy fox]

yeah I've already more than confirmed the object being hit is WallEZ

[real merlin]

and how should i create an array of action variables ?

because apparently it's a "delegate"

i wonder what that is

[swift crag]

"delegate" is the type of a function

[tropic dirge]

can someone help ne rq

[real merlin]

ooh

[swift crag]

it's not an array of variables or anything; you're just making an array of System.Action

            System.Action[] x = new System.Action[3];

[rocky canyon]

        // Create an array of Actions
        Action[] actions = { action1, action2, action3 };```

[tropic dirge]

nvm

[real merlin]

alright i see

thank you very much

[swift crag]

oh, I guess that is kind of an array of variables :p

in a sense

[rocky canyon]

just called it "Actions"

[sly wasp]

https://pastebin.com/wPAVLDst I got a script here that controls blendshapes, it works but is very annoying to constantly edit the strings of the blendshape name. Is there a way to get the component of the first second and then third blend shape? Kinda like m_Animator?

[swift crag]

"get the component" ?

you mean you want to save the blendshape indices?

[spiral rain]

Hey I am trying to make a random scrolling animation that selects a item (like what it looks like when choosing a mini game in Mario party) does anyone know how to make it or better yet a tutorial.

[sly wasp]

I am not really sure how to explain it well, I mean like in the order. So The first one is 0, second is 1, third is 2. I need it to access those rather than me typing a string and it finding it

[edgy fox]

reacreated the scene re-using my scripts and obv 3D assets - same issue and I don't really know what I should change unless I just go through the process of re-coding all of my room generation functions

[rocky canyon]

maybe you can find something similar by searching Slot Machine ?

[swift crag]

Just use 0, 1, 2, etc. in that case

[rocky canyon]

thats kinda what i think of when i hear random scrolling selection

[swift crag]

the blendshapes are numbered in order

(as far as I'm aware, at least)

[sly wasp]

yeah but how do i do that in code.

[swift crag]

I'm still unclear on what your problem is (and I don't think you've shown me the code?)

[swift crag]

just...use the numbers

write a for loop

[edgy fox]

Hello Guys
I Have a noob problem i imported a project into unity and when i try to open code from the project it doesn't seem to know where to open it, it does open Visual Studio so i have the right editor chosen.

[swift crag]

I don't know what "doesn't seem to know where to open it" means

[rocky canyon]

i can only wish you luck mate @edgy fox as idk, but im gonna guess its ur system..
if u hand place the piece in front of a gameobject and then use a normal raycast method on that object. like put it on a gameobject and raycast forward with a mouse click or something) just to ensure my raycasts are working.. and debug what it says, etc

[sly wasp]

THANK you so much! You've helped me so much, you've helped me with avatars and this, may not be much but it's really good!

[rocky canyon]

if a basic raycast works and detects that object the way it should. it'd be atleast a little knowledge you have

[silver sierra]

dumb shit: im instantiating a game object to clone it but for someeee reason when i clone it several times it goes like this:
cube (clone)
cube (clone) (clone)

[swift crag]

and can you explain what's exactly wrong here?

[swift crag]

yes, it sticks (clone) on the end of the original name

it sounds like you're cloning the clone

[bronze yacht]

It doesnt know what path maybe? This is what i get when trying to open the code

[edgy fox]

the raycast is hitting an object that it should be missing

[silver sierra]

idk how i am tho im instantiating a game object

[swift crag]

well that's exactly how you clone something, so it sounds relevant..

[rocky canyon]

u should make a prefab and instantiate it.

not an actual object from the scene

[edgy fox]

the red line is the raycast, it is "hitting" the white and orange wall

[swift crag]

sounds like you aren't instantiating a prefab, yes

[edgy fox]

how do I convert an object with children into a prefab?

[swift crag]

I can't see anything in this image. It's a small red line in what appears to be empty space

Do the walls not have backfaces?

[silver sierra]

ohhhh hold up

i got it

[swift crag]

Rotate the view so I can actually see what it's hitting

[edgy fox]

it's not hitting anything

it's "hitting" the wall circled in green

[silver sierra]

sorry my brain fell out my ears then but i got it now thankyou

[thorn holly]

so i have this script, basically it runs a fight seen. Is there a way to execute a method that does something, wait until the player selects one of three options, and then continues doing stuff?

[rocky canyon]

make it a prefab,
drag in that prefab into the script instead of teh gameobject from teh scene

[rocky canyon]

cool stuff 👍

[swift crag]

how do you know that ray isn't from another hit? Are you getting exactly one hit in this image?

[edgy fox]

exactly one hit, Debug.Log says it is hitting WallEZ, the orange and white wall of which only one exists

[silver sierra]

basically it was a script error, where i was calling and instantiating the game object weirdly but i changed how i did it once i spotted it

[rocky canyon]

if u can figure this out Fen you'll solve an issue he's been having for days i think lol

[edgy fox]

weeks actually, it's such a simple yet weird bug

[swift crag]

and Collapse is off?

[edgy fox]

collapse?

[swift crag]

it's an option in the console to hide identical messages

it could bemaking it hard to tell if your'e getting multiple hits

[edgy fox]

oh yeah it's off

[swift crag]

although, you log i in there, so it would separate the messages out.

Show me the console after the code runs.

[swift crag]

is blank an EZWall prefab?

[lone sable]

Anyone know what as of late, VS Code doesn't want to auto complete unity stuff for me?

[swift crag]

run through the !ide instructions

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[swift crag]

should wake it up

[lone sable]

Already have.

[swift crag]

this is especially important if you were previously using the Visual Studio Code Editor package

are you using that package?

check in the package manager.

[lone sable]

Nope. I uninstalled all packages/extensions and reinstalled them all, still not working.

[edgy fox]

blank is a blank GameObject with a hitbox. It does not have wallMask.

[swift crag]

actually, you know, on second thought -- I don't get completions for message names...

[edgy fox]

when blank is clicked, it allows a wall to be placed

[swift crag]

okay, so EZWall exists in the scene from the start

[edgy fox]

and blank is a parent of the added walls

[edgy fox]

correct

[real merlin]

is there any way to get the index of an array while you're doing a foreach loop ?

like the index it is in

[swift crag]

check the size of the EZWall's collider while the game is running

[swift crag]

If you need the index, I'd just do a regular for loop

i do wish we had Python's enumerate

[edgy fox]

1 room by 1 room size

[tepid cove]

its quite vague but right now i have a pitch black scene with no skybox and just use inside roomswith inside light, but i want to have lighting from the skybox of however you do it to get a lighting scene like this:

[real merlin]

i don't get what you mean

[tepid cove]

but direct lighting just flashbangs my whole scene and goes through walls

[swift crag]

for (int i = 0; i < array.Count; i++) { // ... };

[rich adder]

do you have both sides of the mesh?

[swift crag]

You need reflection probes.

Otherwise, every surface will reflect the skybox.

This is not a code problem.

[swift crag]

I was wondering if the collider was getting stretched at some point.

Doesn't seem like it.

sanity check this by turning off the EZWall collider

[real merlin]

but then how do i get the variable that's in the array ?

[edgy fox]

yeah that was a previous issue I had but adding a child 1x1x1 blank GameObject fixed scaling

[swift crag]

surely you've indexed an array before

array[i];

this is no different from any other array!

[real merlin]

oh right i'm stupid

thank you very much

[swift crag]

this should make the raycast miss

[edgy fox]

WallEZ with no collider fixes the false positive issue but removes all true positives

[tropic dirge]

it took me 25 minutes to make a account for unity again

[edgy fox]

and yeah it does miss

[swift crag]

okay, so it is striking that collider, good

[tropic dirge]

because the emails they where sending wherent going to the correct gmail

[edgy fox]

yeah I have reverified that over and over again but I get that - literally every sign is pointing to it being not that collider

the only thing I can think of is that the raycasts are shooting from the center of the wrong room - the room that the wall is a child of, and then being translated somehow back to the room being placed

because if I add 4 walls, it shoots 4 rays out as if the room being placed had 4 walls

(the white line means there is a wall there but transparent so you can actually see into the room)

[swift crag]

that's because it's registering four hits

[tepid cove]

can i use raytracing instead of reflection probes?

[swift crag]

that is useful information

[swift crag]

I am unfamiliar with raytracing.

you generally don't use it for everything

[tepid cove]

when i add direct lighting

[edgy fox]

yeah and if I move one of the wallEZs' colliders, the raycasts from newRoom (not a term in the code, will use that term from now on as newRoom and oldRoom need to be distinctly communicated) are longer/shorter depending on how I move them

[swift crag]

oh, I see: that ray is shooting up and left

I was interpreting it as going down and right

[edgy fox]

it extends straight left/right/forward/back

it's a grid system

so far at least

[real merlin]

it says i can't use < between an int and a non int, but it also says array.Count returns an int

[swift crag]

oh, wrong name!

array.Length

[real merlin]

ooh

[swift crag]

Count is an extension method from LINQ that's used to count any enumerable

[edgy fox]

quick little diagram

[real merlin]

what's linq ?

[edgy fox]

and there are no vertical components to the raycasts at all

[swift crag]

System.LINQ provides extension methods to do various things with enumerables, like ordering and summing them

[swift crag]

well, up and left in that image :p

[edgy fox]

ah alright, I'm internally in my head using my own coord system

with which direction is up changing depending on my mood

but yeah I think you understand how it all is

[swift crag]

(also, instead of raycasting, I would just remember which sides have walls assigned already)

[edgy fox]

that would work

and then I would just need to detect which sides already have rooms

[swift crag]

so where is AddWalls in this situation?

[edgy fox]

wym?

[swift crag]

is it attached to the room frame?

[edgy fox]

oh yeah

it is

with room being a blank GameObject with my custom coords in the title and frame having the scripts

and WallEZHolder being the blank GameObject that holds WallEZ

[languid spire]

pro tip, dont use x,y,z use N,S,E,W,U,D then you can convert those to actual Unity cords when you instantaite Go's

[rocky canyon]

Cardinal Directions are great when working on top down type stuff

[edgy fox]

yeah and for right now my game is essentially a glorified top down game

[rocky canyon]

another thing is to keep ur eye on scaling.. if ur rooms/walls are child objects and they're all using primative colliders like a box collider or what not.. it could be that certain positions or rotations might wig out the actual fitment of those colliders

[meager raptor]

    public float minY = 20f;
    public float maxY = 120f;
    public Vector2 mapLimit;
void ClampPosition() {
    newPosition.x = Mathf.Clamp(newPosition.x, -mapLimit.x, mapLimit.x);
    newPosition.z = Mathf.Clamp(newPosition.z, -mapLimit.y, mapLimit.y);
    newPosition.y = Mathf.Clamp(newPosition.y, minY, maxY);
}```
trying to set camera limits, so it doesn't go off the map etc
problem: newPosition.x and newPosition.z works (WASD keys) , but not newPosition.y (scrollwheel), why is this?

[rocky canyon]

i tend to try to use 3d modelled colliders with scales of 1:1:1 to keep everything as proper as possible.. just a little helpful tip

[edgy fox]

everything that is repeatedly cloned has a parent blank object with 1,1,1 scaling to maintain scale

[rocky canyon]

just making sure, lol im just trying to cover all bases

[edgy fox]

yeah no worries lol

earlier I had a funny glitch where you could make WallEZ repeatedly bigger by clicking on a wall repeatedly which was fun

[rocky canyon]

😄 not a bug, a feature

[edgy fox]

artist's recreation

[rocky canyon]

ship it

[thorn holly]

my cursor is stuck as a vertical arrow in unity, does anyone know whats going on?

[edgy fox]

but in seriousness, just using a neighbor finder that finds rooms instead of walls and finding the NSEW of the walls will be helpful because then I just need to find the neighboring rooms (code already written) and see if for example the room is to the west if that room has an eastern wall

[thorn holly]

i havent saved in a while so id rather not close out of unity and reopen it

[edgy fox]

save and then close and reopen

[thorn holly]

well how do i save if my cursor is stuck like a vertical arrow

[swift crag]

ctrl-s

[edgy fox]

ctrl

[thorn holly]

ah

[edgy fox]

ctrl s

[swift crag]

or by just clicking File -> Save Scene anyway

[swift crag]

Does this behavior continue if you add more rooms?

so, one 4-walled room, then several 0-walled rooms

do they all wind up getting four hits on the walls?

[edgy fox]

yeah all adjacent rooms do

[lone sable]

So yours is also not doing this now? Wonderful.., Thanks Microsoft.

[swift crag]

well, I don't think it's ever been completing those messages, specifically

[thorn holly]

didnt work, thats quite a bit of progress gone

[swift crag]

it's completing everything that the static analyzer is actually aware of

[thorn holly]

thanks unity, for having a seizure

[swift crag]

do you mean it was frozen?

because it doesn't matter if the cursor looks funny

that doesn't stop you from doing things

[thorn holly]

it must have been

[swift crag]

and what if you add walls to the second room, then place a third room?

[edgy fox]

and if multiple rooms with walls are adjacent to the placed room itll still register

this setup for example triggered 12 times

4 for each of the 3 adjacent room

which really backs up my hypothesis the for loop runs for each of the adjacent rooms rather than for the room itself

[swift crag]

I think you're instantiating something incorrectly.

[edgy fox]

wait I lied it only generated 7

I do too

[swift crag]

so you placed 3 rooms and gave them 4 walls each

then you cleared your console and placed the room in the middle, and that caused 7 hits?

you should make sure you weren't just seeing old hits

[tropic dirge]

see yall in another few months

[edgy fox]

I miscounted - 4 hits

[tropic dirge]

unity didnt want to work so im gonna be back later

[edgy fox]

so it is still maxing out at 4 which makes sense as the for loop runs 4 times

I had 12 messages but each of the 4 times it happened I have 3 messages per hit

[swift crag]

well, that is way more than there should be

ah, I see what you mean

3 log entries

Are all four hits from the same room's walls, or do they vary?

[native seal]

is there any difference between doing it either way?

[swift crag]

the latter would require you to add [field : SerializeField] to each of the three properties so that they appear in the inspector

[native seal]

oh yea true, other than that?

[swift crag]

I generally prefer the former. It's less annoying if you want to rename or change how DamageBonus works

If you decide it should be something other than just a getter for a field, then you have to take care to migrate the serialized data over

with [FormerlySerializedAs]

[native seal]

how so?

oh since it will mess my items up

[swift crag]

the property will have been serialized as something like field_damageBonus by Unity

i forget the exact name it uses

[edgy fox]

I'm going to be honest I can't tell

[swift crag]

Click on the second log entry in each group. You used hit.transform.gameObject as the second argument to debug.Log

"Hit object ..."

that will highlight whatever you hit

[edgy fox]

did that, doesnt highlight

only in this specific case though

it's weird

[swift crag]

Then the object doesn't exist anymore.

I wonder if your wall-attaching code is doing something bad here.

[edgy fox]

That's what I thought, but there is no code to destroy an object

[swift crag]

Perhaps the new rooms are winding up with walls that are instantly destroyed

or that are otherwise moved or made irrelevant

[edgy fox]

no object with the proper layerMask to intercept the raycast is created or destroyed

the hit coords

[queen adder]

What is the code to detect when the image moves???

I don't remember what code it was

[shrewd swift]

is there a faster way to generate a random boolean rather that using a Random.Range ?

[ivory bobcat]

You'd have to code it.

[swift crag]

Random.value < 0.5f is pretty simple

[ivory bobcat]

Random value > 0.5f

[swift crag]

that might be slightly off because Random.value goes from 0 to 1 inclusively

(annoyingly)

[ivory bobcat]

They'll never notice

[thorn holly]

I have this code here:

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            Debug.Log("Space Pressed");
            movePlayer();
        }
    }

    IEnumerator movePlayer()
    {
        selectedPosition = currentPosition;
        Debug.Log("selected position:" + selectedPosition);
        Debug.Log("current position:" + currentPosition);
        yield return new WaitUntil(() => selectedPosition != currentPosition);
        currentPosition = (SpacePosition)selectedPosition;
        player.position = new Vector3(0.5f + ((((int)currentPosition) - 1) * 2), transform.position.y, transform.position.z);
    }

For some reason, the second and third debug logs aren't running, indicating that the IEnumerator isn't running. The first debug log, however, does run, so it is registering that I pressed space.

[ivory bobcat]

Start Coroutine

[queen adder]

What does it mean? Do I have to look up the code?

[ivory bobcat]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.StartCoroutine.html

[thorn holly]

oh, i thought i could just run it like a method

[ivory bobcat]

There isn't a callback for an image being displaced. You'll probably have to poll the difference between the previous and current position to see if a move was made.

[rare basin]

its not a normal method

it's a coroutine

[thorn holly]

fair enough

[rocky canyon]

    void Start()
    {
        // Call the Coroutine using StartCoroutine
        StartCoroutine(YourCoroutine());
    }

    IEnumerator YourCoroutine()
    {```

[swift crag]

if you run a method that returns IEnumerator, it will execute everything up to the first yield

then it'll stop and return an IEnumerator

if you discard that return value, nothing more will happen

[rocky canyon]

like when an unwanted kid shows their parents their trophies

[thorn holly]

ah

thanks

[rocky canyon]

it can work just like a normal method tho

[rocky canyon]

😄 being a game developer ends up in some crazy search history

i feel im obligated to tell anyone that see's it.. "hey, im a game developer btw"

[edgy fox]

I could have commented the function better but to be fair that documentation is my most memorable comment I've ever written so

[rocky canyon]

i started using [Tooltips] here lately instead of comments

i mean, it doubles as a comment when u read the script

[edgy fox]

yeah ofc

thats interesting

[rocky canyon]

tbf these variables were confusing to me at first.. and then i got the Min and Max flipped around

[queen adder]

I have another question, is it possible to change the texture of a block with a script?

[rocky canyon]

easier to assign a new material using the new texture

if you try to change the texture i believe you'll have to copy the material the block is using, change the texture on the copy and assign the copy to the material used

[queen adder]

I mean, I want to detect the image when it moves and the texture changes automatically 😕

[rocky canyon]

erm.. 🤔 interesting. care to elaborate a bit? still a bit confused what you mean by when it moves

like a sprite? like animation?

[queen adder]

Sorry, I don't speak English very well, I speak French

I'm trying to do it when I press the image and move to whatever it is but I want the texture to change when it moves and when I stop moving the normal texture returns

I would like to know if there is any code to change the texture or something like that

It doesn't work for me with event triggers because it gets bugged and that's why I decided to use codes

[rich adder]

they just told you how, swap the materials

event triggers only works if you put a 3D physics raycaster on the camera

otherwise its meant for UI / Canvas

[rocky canyon]

all you need to do is check if its moving

if(thingIsMoving){//use one texture}else{//use another texture}

not sure if ur using a rigidbody to move the thing, but whatever ur doing theres a way to tell if its moving.. just use an if statement

https://hatebin.com/lqrcvmhqqe it would look similar to this

where you pass in w/e material u want to the ChangeMaterial() method..

[queen adder]

Thanks you!!

I really appreciate you for making example code

[rocky canyon]

if ur just moving the object with the mouse u can probably write ur own method that gets the last position and the new position in each frame

if they have changed its moving.. if not its not..

 private Vector3 lastPosition;

    void Start()
    {
        lastPosition = transform.position;
    }

    void Update()
    {
        // Get the current position
        Vector3 currentPosition = transform.position;

        // Check if the position has changed
        if (currentPosition != lastPosition)
        {
            // Object is moving, change texture to movingMaterial
            ChangeTexture(movingMaterial);
        }
        else
        {
            // Object is not moving, change texture to idleMaterial
            ChangeTexture(idleMaterial);
        }

        // Update lastPosition for the next frame
        lastPosition = currentPosition;
    }```

[swift crag]

it was caused by delayed destruction

sneaky one!

[warm condor]

hey, do you guys know what this error is?

[polar acorn]

It means something on that line is null but you're trying to use it anyway

[native seal]

would it be a good idea to use a dictionary for an item equipment system? (equipped items on the player, stats, etc) if not how should I handle it?

[warm condor]

how do I fix that?

is it a problem in unity or in my code?

[polar acorn]

Make it not be null

[rich adder]

something is null at runtime, its not the code per se

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[thorn holly]

is there a way to add a courotine to a delegate in the same way you would add a method?

[warm condor]

hmmm, I tried to double click on the error and it seems that it is complaining on this line
isJumpSliding = timer.startTimer(jumpSlidingValue);

over here I am accessing a method in a c# script

[rich adder]

so timer is null

[warm condor]

how? I don't understand what null is?

[rich adder]

did you read the link I've sent

[warm condor]

yea

[rich adder]

so it means the computer doesn't know which timer you want to run startTimer from, therefore nothing is there, hence Null

make timer not null

assign it

[warm condor]

you mean like this?

[modest dust]

That's declaring a variable

Assign an instance of that class to it

Timer timer = new Timer();

[warm condor]

ohhhhh ok I see

[north kiln]

The link is longer than one page, it's a whole damn resource that explains the concept from top to bottom

[rich adder]

this is confusing to newcomers because this isn't how you assign MB instances

[meager raptor]

UnityEditor.EditorApplication:Internal_CallDelayFunctions ()```

what is this error? google tells me to reset all layouts, clicked that and doesn't work, what's going ?
error appeared when i created a new scene

[rich adder]

you tried restart editor ?

[swift crag]

I see that every time I start my editor. I should probably reset my layout..

[meager raptor]

ill try that thanks

[modest dust]

That's why a C# course should be done first before Unity

[meager raptor]

worked, thanks

[rich adder]

agree but this channel people want to make a game and forget you need basic c# knowledge

[modest dust]

He was probably confused because of value / reference type differences

[warm condor]

oh, so how do you do it?

[modest dust]

structs and other value type fields get initialized with their default constructor so they're ready to be used

[swift crag]

you are not allowed to directly construct a monobehaviour

[modest dust]

default value for classes is null

[rich adder]

the symbol is the same = for assigning anything

[swift crag]

instead, you tell Unity to add a component to a game object. you can then store the reference it returns.

[rich adder]

but the issue is Monobehavior scripts are instantiated when they are on the object

so unlike regular C# class you don't need to new() an instance and use either a serialized field or the GetComponent method

[swift crag]

i don't understand what you mean by that

[rich adder]

I meant when you attach a MB to a gameobject unity does its black magic to take care of the instancing

[swift crag]

Unity just forbids a MonoBehaviour from existing without being attached to a game object

hence why you have to ask it to create components for you

[rich adder]

yeah thats what I kinda meant, the instance is made by unity by being attached to gameobject

[thorn holly]

huh

digi was right

once you know how a delegate works, you wont know how you lived without it

[swift crag]

delegate types open up higher-order programming

yum

[rich adder]

helle yea!

[warm condor]

so what I have to do is use GameObject.GetComponent to an object that I want to access the c# script, no?

[rich adder]

Observer pattern I think is the technical term no?

[rich adder]

you use GetComponent to get that Script so you can use it

[thorn holly]

d e l i c i o u s

[rich adder]

or better to just Serialize the field in the inspector with public or [SerializeField] and assign by drag and drop @warm condor

[swift crag]

If you have a reference to a game object that has the component you want, then you can use GetComponent<TheComponentType> to get it.

It is preferable to just get a reference to the component itself.

[SerializeField] MyComponentType target;

drag something into that Target field in the inspector

done

[warm condor]

oh I see, and MyComonentType should be what? the game object or the script?

[rich adder]

the script is the type

[north kiln]

The script type. Don't reference things via GameObject unless you only want to perform GameObject functions

[warm condor]

it seems that it doesn't recodnise the compnent type tho
[SerializeField] Script timer;

[rich adder]

why did you write script, I guess you took "the script" too literal

[north kiln]

do you have a type called Script?

[warm condor]

i mean idk what to put there so I just wrote script

[rich adder]

isnt your class called Timer

you declared it as such

you already have that part

all you need to add is the [SerializeField] so you can assign it in the inspector as said

[modest dust]

Taking a C# course followed by !learn would be probably a better solution to all of this

this is your current issue to learn

[rocky canyon]

wait yall solved it?!

[warm condor]

yea your right. I am ne wto c# and unity in general and I have been leanring it while making the game because I already have programing experience in college.

oh and btw I have fixed the problem so thanks for that

[swift crag]

it required more context; adding a new room involved instantiating the neighboring room and destroying its existing walls

deactivating the walls before destroying them ensured they were gone in time

[rocky canyon]

epic!, glad u got it worked out, i was starting to feel bad for the guy lol

[rich adder]

did you program in C# though cause a lot of this is basic c# knowledge like assignment, the only difference here is the Unity API

[swift crag]

I was a little surprised that it worked, though, since the offending logic ran in the Start method of the instantiated room

[rocky canyon]

yup, it rings a bell.. ive had errors caused by Destroy() not being Immediate

[swift crag]

the clue was that clicking on the logs didn't take you to a game object

even though the hit wall was included as context

[rocky canyon]

bc it didnt exist! 🤦‍♂️

[swift crag]

(any longer (: )

[warm condor]

no I was programming in python in school

[rocky canyon]

clever debugging 👍

i overlooked that fen

i knew u'd boss it

[rich adder]

ahhh yeah...wildly different than C#

[swift crag]

C# will differ in one major way: it is statically typed

(Python has type hints, but those are optional)

[rich adder]

I suppose you still have classes and all that like js but you need typescript for similiarity

[north kiln]

I feel like they just hid an entire script from me that was also instantiating and deleting objects, and said they weren't destroying any of them

[rocky canyon]

vscommunity can be set up to have type hints

helpful to me so i dnt have to peek definitions all the time

[rich adder]

its on by default no ? I was trying to turn off but ended up just loving it

[swift crag]

⚡

[rich adder]

makes things a bit verbose to look at but you get used to it

[swift crag]

zap

indeed

context is important (:

[rocky canyon]

thats why i suggested a blank scene with a hand placed wall..

i knew the raycast stuff didnt seem broken

[swift crag]

The red herring was the belief that the raycast was hitting the existing wall

[north kiln]

#💻┃code-beginner message
Like did they literally have a function called Kill Children?

[swift crag]

which murders the children, yes

[rocky canyon]

i think so yea

[north kiln]

in a completely different script that I never saw

just so fucking dumb

[swift crag]

the plot twist was the instantiation of the existing room

[rocky canyon]

important thing being it works now.. 😅

[north kiln]

plot twist was that there was this entire other piece of code instantiating and destroying walls that was never mentioned

[swift crag]

I've done that a few times, but generally only to make recursive prefabs that create the child copies before modifying themselves at all

[rocky canyon]

ill have to remember the manage my destroyed objects better

so i dont run into a similar issue

[swift crag]

well, it's only really going to come up if you're cloning existing objects and then trying to clean them up

[rocky canyon]

true true, but when you destroy() an object it doesnt actually get destroyed until the end of that frame correct?

thats just something i need to watch out for (on my own projects)

[rich adder]

iirc its marked for cleanup until GC comes in no?

[swift crag]

Correct.

[swift crag]

That's a different thing.

You're thinking of C# objects.

[rich adder]

ahh ok

[swift crag]

we're talking about UnityEngine.Objects

[rich adder]

gotcha mb for butting in 😓

[rocky canyon]

you good.. we're a community 🙂

[meager raptor]

noob question but how do i drag the text (like there's a box around it so i can move it about)?

[rich adder]

the unity lifecycle of objects is def something I should learn more 😓

[swift crag]

you're in the game view right now

you can't move things around in the game view

switch to the scene view

[rich adder]

also might want to toggle 2D

[meager raptor]

thanks 👍

[rich adder]

click your text obj in hierarchy and press F

[meager raptor]

gotcha

[rocky canyon]

in the scene view.. you can use the regular tool.. or this other one

cant think of its name

[rich adder]

Rect Tool iirc

[rocky canyon]

the Rect tool yup

just had to watch the clip myself 🤣

[rich adder]

to many times in my earlier days "WHERE ARE MY ARROW GIZMOS"

oh wait Im in Rect tool mode

[swift crag]

It’s available when editing something with a RectTransform on it

I mostly use it to make it easier to see where the bounds of the selected object are. They can get lost in complicated UIs

[rocky canyon]

u can actually use it for anything 😄

i use it to offset scale my objects sometimes

OP tricks

[rich adder]

Oh yeah thats interesting you can resizing one side only

[north kiln]

ah, the usual axes: M, C, P represented by magenta, cyan, and purple

[swift crag]

Oh right. It works for some other components as well

[rocky canyon]

lol, i wanted to try out pastels for a bit

[rich adder]

how did you change that?

[swift crag]

It’ll leave you handle-less when you select a light

You can change a frightening number of colors in the settings

[rocky canyon]

in the big mass of editor colors stuff

[north kiln]

in the Color preferences

[swift crag]

Way too many colors

[rich adder]

Oh wow I thought you can only change playmode tint, I shouldve checked them

thanks!

[rocky canyon]

nah, u can go down a rabbit hole..

[faint osprey]

{
    public GameObject leverUnswitched;
    public GameObject leverSwitched;

    public bool hasActivated = false;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    private void OnTriggerStay2D(Collider2D collision)
    {
        if (Input.GetKeyDown(KeyCode.E) && hasActivated == false)
        {
            Debug.Log("working");
            hasActivated = true;
            leverSwitched.transform.position = new Vector3(0, 0, 1);
            leverUnswitched.transform.position = new Vector3(0, 0, -5);
        }
    }
}``` why is this not modifying my transform.position for both variables

the debug.log is being called

[polar acorn]

Do you have any errors

[faint osprey]

nope

[polar acorn]

Do the objects you're trying to move have CharacterControllers

[faint osprey]

no i thought if they had transform it wouldnt matter

[swift crag]

a CharacterController would interfere

[polar acorn]

What are those two variables set to

[faint osprey]

2 tilemaps

[polar acorn]

Are they objects in the scene or prefabs

[faint osprey]

ive got it working now

however its really janky

like sometimes i press e and it does nothing

and then just magically works one time

[polar acorn]

Because you're checking input in fixed update (onTriggerStay runs in FixedUpdate)

[faint osprey]

i thought it ran every frame your in the collider

[rocky canyon]

no fixedupdate (default settings) runs 50 fps

[polar acorn]

It runs every physics step you are in the collider

[faint osprey]

it says every frame

[polar acorn]

While input checks on frames

[rocky canyon]

means the method is ran only once for each physics frame that runs im sure

[rocky canyon]

as opposed to multiple times per

[faint osprey]

huh why doesnt visual studio say that

[rocky canyon]

put a debug in the update and one in the fixed update.. you'll see how differently they are

[clever edge]

yo can you have rigidbody2D velocity instantly accelerate instead of slowly

[rocky canyon]

they probably could phrase it differently.. but im assuming its common knowledge so they dont go into deep details

[rocky canyon]

you can use an Impulse force mode to have the entire force happen at once

could also just set the velocity manually..

[rocky canyon]

theres no code to turn it back..

[clever edge]

i thought i was already doing that?

[rocky canyon]

if ur not pressing a left or right nothing happens

how would it rotate back when theres no code to run?

[supple needle]

Yea ik but what should i do ive tried a lot

[rare basin]

Make a logic to turn it back

[supple needle]

Ah mb

[rocky canyon]

u can add teh rotation after the if statement... and just change it back in the else statement

[true pasture]

I feel like theres a better way to do this (this doesnt even work) I'm just trying to see if the object I clicked has stats

[tall delta]

well either the raycast didn't hit anything, or the thing it hit doesn't have a Stats componenet

[supple needle]

So i just rotate back using rotation function in the else statement ok imma look at that

[rocky canyon]

something like that

set the rotation to be facing forward or w/e then outside the if u can just use whatever rotation you use

[supple needle]

I use the GetAxis Horizontal thing, so i just need to set it to rotation(0,0,0) right?

[rocky canyon]

      // Get horizontal input
        float horizontalInput = Input.GetAxis("Horizontal");

        if (Mathf.Abs(horizontalInput) > 0.1f)
        {
            // Set the rotation based on input
            RotateSteeringWheel(horizontalInput);
        }
        else
        {
            // No horizontal input, set the rotation back to zero
            SetRotationToZero();
        }```

could do this..

[supple needle]

Woah, nice

Thanks ill have a look!

[rocky canyon]

i was thinking more like this tho ```cs
void Update()
{
float horizontalInput = Input.GetAxis("Horizontal");

if (Mathf.Abs(horizontalInput) > 0.1f)
{
    desiredRotation = CalculateRotation(horizontalInput);
}
else
{
    desiredRotation = 0f;
}

RotateSteeringWheel(desiredRotation);

}

so the steering wheel always rotating after the if/else statement.. but its the if/else statement that would set w/e rotation u want

[supple needle]

Im getting confused

[rocky canyon]

this will always run

[supple needle]

Ohh gotcha

[rocky canyon]

the if statement just sets what desiredRotation would be

[true pasture]

would a virtual camera with cinemachine mess with it?

[supple needle]

Yayaya i understand

[rocky canyon]

a cinemachine virtual camera is like a placeholder.. the camera just gets positioned to where the virtual camera is..

still functions exactly like the main unity camera (b/c thats what it is)

[rocky canyon]

you say hit.collider.GetComponent

just remember that its trying to grab the component from the object with teh collider..
(that may not necessarily be the main root gameobject, for example if ur collider is on a child object of it)

but if theres no Stats.cs or w/e it'll be null.. if there is one it'll find it..

if(hit.collider.TryGetComponent(out MyScript myScriptReference))
{
   myScriptReference.DoFunction();
}``` ```cs
MyScript myScriptReference = hit.collider.GetComponent<MyScript>();

if (myScriptReference != null)
{
     myScriptReference.DoFunction();
}```

both of these do the same thing

you can Debug.Log(yourReference); to make sure its getting assigned (or not)

[edgy fox]

how many children would Room (0, 1, 0) have? Would it be 5 or would the children of the children such as WallEZholder(clone) be considered children as well?

like if I do transform.GetChild(2) would I get roof or BlankEast

ah its the former

[rocky canyon]

did u debug it?

thats how id find out real quick

[edgy fox]

Instantiate(wall, hit.transform.position, Quaternion.Euler(new Vector3(0, hit.transform.eulerAngles.y + 180, 0)), transform.Find($"Blank{(NSEW)i}"));

why does this code not make the wall a child of Blank{cardinalDirection} - if I debug log it transform.Find($"Blank{(NSEW)i}")); returns null

yeah debug logged it to find out which one it was

nvm I'm dumb, the transform is the fram's transform

not Room's transform

[rocky canyon]

Rubber 🦆

[edgy fox]

still doesn't work

Debug Log still returns the child obj though

but now it just doesn't instantiate anything

[polar acorn]

Store the result of instantiate in a variable. If you pass that object to the second parameter of debug.log it'll highlight that object in the hierarchy when you click the log

See if that object is where you expect it to be

[edgy fox]

huh it doesnt highlight anything

||deja vu||

[polar acorn]

Then it's probably destroyed between the time you spawn it and click on the log

[edgy fox]

yeah

oh I know what the issue is

all children are killed and remade fresh when a new room is made

and this runs the same frame they're destroyed before new ones are made

is there a way to cache a command to execute next frame

[acoustic violet]

im not sure set it to an instance of an object

[rich adder]

how did you assign TimesClicked

[polar acorn]

TimesClicked is null
