For simpler issues you can typically just reread the code. If you can’t find where your bug is by reading it you likely have to refactor for readability. Testing via debug.log can also help.

For more complex issues, unit tests can sometimes help.

[elfin isle]

ty guys lmao

[thorny basalt]

NP.

[charred spoke]

Don’t forget the most important thing…using the debugger to step through your code and see what happens.

[rocky canyon]

anyone know what the easiest/best method of removing these broken installs?

[rich adder]

reinstall windows lol

[naive pawn]

uninstall windows lol

[rocky canyon]

🇫

i guess regex it is

[shadow rain]

does anyone know how to fix this?

[rich adder]

omg unity

which intern did this

[rocky canyon]

ill never trust unity vc or plastic

[rich adder]

same problem within the hour, its gonna be one of those lol

better patch quick

plastic sucks anyway

[shadow rain]

what should i do tho?

[rich adder]

try remove VC package?

[shadow rain]

nvm

its all good

i just reopened unity and it was gone

[silver forge]

i was coding a simple player movement script, but for some reason the jump code makes it so i am continuously launched in the air with no input. it gets worse the more i try to fix it

[verbal dome]

Code looks ok. Show your character's inspector, all components it has and its children's components too

[verbal dome]

Okay so CharacterController will not work with Rigidbody. Both will try to move the character = 💥

You need to pick either one

[silver forge]

oh yeah

forgot to remove that

damn i'm stupid lmfao

tysm

[rocky canyon]

save ur scene

[flat sphinx]

?
as in var thing = GameManager.us?

[cosmic quail]

yes

[wintry quarry]

You could also just write a shortcut method

[flat sphinx]

i dont think a shortcut method would be faster than either GameManager.us.whatever() or in the cases of method spam (which you wouldnt run into if your code is halfway decent) var us = GameManager.us; us.whatever()

[naive pawn]

it wouldn't be faster

[flat sphinx]

to type

[naive pawn]

it could be more convenient

but i mean, intellisense is a thing anyways

if you're using the same method in a bunch of places, it could make it more convenient

[flat sphinx]

oh you're refering to GameManager/proc/whatever() { return us.whatever();}

ehhhh i mean it would work

i dont like bridges tho, still have ptsd over a mountain of shitcode built on it

do have a bit of a skewed outlook since to me less wrappers == cleaner code

[verbal dome]

With method spam you excessive amounts of method calls or what?

[flat sphinx]

as in like

//set stuff up
GameManager.us.do_x()
GameManager.us.do_y()
GameManager.us.do_z()
GameManager.us.do_w()

[verbal dome]

What's wrong with that

If the issue is that it does GameManager.us repeatedly, I would assume that the compile probably optimizes that

[flat sphinx]

lets take an example from my code
so im doing golf, and one of the things i needed to do was a sick ass animation of every element floating away when the ball goes into the hole

now i could do some

void OnColliderEntry(gameobj){
  if(gameobj.hastag("ball")){
    var gm = GameManager.us;
    us.yeet_map()
    us.load_new_map()
    us.spawn_ball()
  }
}

ball whatever code

but realistically all of it should be in us.load_map()

the hole handling loading the map aside

[verbal dome]

Agree

[flat sphinx]

now im not saying "dont have functions that do a lot of stuff"
but if you're calling a bunch of stuff on a diff class perhaps said class should have a proper handler for that

[verbal dome]

Yeah. And ideally you'd make these private: yeet_map, spawn_ball etc.
So you can't even call them accidentally

[flat sphinx]

ehhh that one is up to preference imo

i personally dont like the modifiers since all that ends up with is me having to correct a private to a public when some new usecase pops up

even if said usecase is nonexistent

[verbal dome]

I do understand that and agree in some cases. But in some cases it's clear that a method shouldn't be ever called from the outside

But yeah worrying too much about encapsulation just slows down my iteration speed tbh.

[flat sphinx]

yuh

[wintry quarry]

GameManager.Wahtever(); seems shorter than both of those to me

[flat sphinx]

yes we came to that conclusion already

[wintry quarry]

less wrappers == cleaner code
Basically the entirety of using a high level programming language and a game engine is to introduce layers of abstraction to simplify the code you need to write

Not sure how this is any different tbh

Wrapping things is how you make things clean in programming

[flat sphinx]

wrappers as in f.e

public bool drop_item_on_floor(){
  return move_item_internal(...)
}

or getters or setters that only just return the var

[wintry quarry]

that's a wrapper that doesn't seem to add anything though, which has no purpose

[wintry quarry]

Those have a purpose, which is to enforce encapsulation

[flat sphinx]

nuuh
that also enforces encaapsulation

[wintry quarry]

not in any meaningful way

the property lets you have a different access modifier on the getter and setter

[flat sphinx]

neither do getters

[wintry quarry]

this one just makes a private method public

[wintry quarry]

disagree, see #💻┃code-beginner message

[flat sphinx]

link doesnt work

[wintry quarry]

yes it does

[flat sphinx]

idk if its a me issue

[wintry quarry]

It just goes back to this

[flat sphinx]

oh

[pallid nymph]

if the internal method has no params - suer, but if the wrapper passes some params to the method, then it's not just making a private method public

[flat sphinx]

well what if i need to mock a var

[wintry quarry]

agreed

[flat sphinx]

i shouldnt have to, but what if i do

[wintry quarry]

What about it

[flat sphinx]

a setter would break stuff then

[wintry quarry]

how so

[flat sphinx]

say im doing chess and i need to mock a piece being in x place
and lets say you have a setter on the piece holder whatever that updates the hud
the mock would erroneusly update the hud

well, update meaning "place a piece on the hud"

board whatever

[wintry quarry]

You wouldn't call that setter in that case.

[flat sphinx]

yeah, you'd just assign to the var directly

[wintry quarry]

Are you arguing against any accessors with side effects at all?

[flat sphinx]

and reset after

[wintry quarry]

because that way leads to madness

[flat sphinx]

im arguing against prohibiting regular var access

in this case setting

[wintry quarry]

That's a huge mistake and inviting way more bugs than the other way around

[pallid nymph]

my usual approach is - make everything private by default, if necessry expose something

[wintry quarry]

This example seems super contrived. Writing a unit test for a chess game you would simply provide the whole game state as a starting point, you wouldn't be calling some in-game setter.

[flat sphinx]

i just skip the privating part since 4 times out of 10 my projs are solo-dev

~~the 6 remaining times are in an engine where access modifiers are through an optional lint ~~

[pallid nymph]

my projects are also solo ones, but it's just nicer to not expose random things and only expose what's meaningful to the outside

[flat sphinx]

its an example i ran into
needed to mock a piece not being/being in x place to check if it would cause a check

[flat sphinx]

yeah but at that point its personal preference

obviously if you're doing a library throwing privates at eveything is prefered

[pallid nymph]

even in personal projects... you can't randomly change many variables from the outside without breaking something, so exposing them makes no sense... make methods that would keep the object in a valid state instead 🤷‍♂️

it's just easier to work with, because in a month you wouldn't strictly remember what's what, and which variable you can modify safely

[flat sphinx]

you can have both

[pallid nymph]

so, while it would work and it's not a strict requirement for a solo project, the moment you're not doing solo it would be, so it's better to get used to it 🤷‍♂️

[flat sphinx]

both public var access and functions that dont leave the program in an undefined state

[flat sphinx]

fair

[violet pagoda]

Which programming language does Unity use?

[pallid nymph]

C#

[violet pagoda]

Is programming only possible using C# or are there alternatives?

[flat sphinx]

realistically only c#

[violet pagoda]

Sorry if I am asking too many questions I am new to using Unity and learning game development on it

[flat sphinx]

no worries

[forest summit]

ive been constantly trying to get this sdk to work, ive tried reinstalling vs code and my computer. I checked my system variables and manually assigned its path. Yet it still doesnt work, if anyone can help that would be awesome

[vital olive]

Hey, I am new to unity and I am acutally working on a Flappy bird game, Do anyone know why my pipes are behind the ground in 3D view but in front of the ground in 2D ?

[slender nymph]

this is related to 2d sorting. your sorting layers determine what is drawn on top. and your z position determines where in the 3d view they appear

with different sorting layers and/or order in layer, the z position isn't taken into account
https://docs.unity3d.com/6000.0/Documentation/Manual/2d-renderer-sorting.html

[rocky canyon]

^ this.. u can actually have all ur 2d objects BEHIND something and have them all render in front of it.. using sorting layers

[vital olive]

Thanks I will read this html file

[late abyss]

why is my "LogicScript" not blue?

[short hazel]

Do you have a class named LogicScript in your project?

I don't see it in the script list in VS

I see a NewBehaviourScript, which is the default script name when you create one, did you forget to rename it?

[rich adder]

because it doesn't exist

[late abyss]

Yes. I forgot to rename it.

[rocky canyon]

aren't u a comp-sci major? that had to learn c++ and python? im sooo confused..

[prime goblet]

i'm trying to get this vehicle to abruptly change from acceleration to deceleration (or otherways) but i'm not sure how to make it more abrupt.

    void FixedUpdate() {        
        if ((goingSpeed > 0 && YInput < 0) || (goingSpeed < 0 && YInput > 0)) { // gets triggered when the player switches
            goingSpeed = Mathf.MoveTowards(goingSpeed, 0f, dccSpeed);
            print("change from acc/dcc dcc/acc");
        } 
        else if (Mathf.Abs(YInput) > 0.1f) { // gets triggered if the player is just holding
            goingSpeed += YInput * (driveSpeed / accSpeed);
            print("going forward/backward");
        } 
        else { // triggered when the player releases all forward input
            goingSpeed = 0f;
            print("stopping vehicle because no input");
        }
        
        goingSpeed = Mathf.Clamp(goingSpeed, -driveSpeed, driveSpeed);
        
        // Driving
        float motor = goingSpeed;
        
        wheel3.motorTorque = motor;
        wheel4.motorTorque = motor;
        
        wheel1.steerAngle = steerSpeed * XInput;
        wheel2.steerAngle = steerSpeed * XInput;
    }

notably it barely ever prints the change print statement, and making goingSpeed = 0 does not really do much in terms of doing lots of slowing

[magic panther]

My project cannot compile because these two functions use AssetDatabase. They're meant to grab a file from the Assets folder, without the need for a Resources wrapper folder.
Class with both functions (GetRuleTileByCodename and GetSpriteFromPath): https://hastebin.com/share/maxunijaqu.csharp

How can I change the functions to preserve the functiionality but remove AssetDatabase from it?

[rich adder]

if its runtime you need to use the functions for runtime, IO, Resources or Addressable

oh and streaming assets ig if you don't consider that IO

[magic panther]

I don't understand

[rich adder]

which part?

AssetDatabase is part of Editor classes, you cannot use Editor classes in a build

alternatives are the ones stated above

System.IO , Resources or Addressables

[untold raptor]

has anyone here worked on motorbike physics before? or more on the wheels part of it. I need help with setting up my bike properly. Im running into the wheel bouncing when torque is added to the wheel collider and the suspension bouncing all over the place

[fair badge]

What collider are you using?

[untold raptor]

wheel collider

[magic panther]

I don't really know how to introduce a Resources folder. Do I place everything inside it, like another Assets within Assets?

[rich adder]

pretty simple, you add a Resources folder and put whatever Sub folders inside you want to grab at runtime
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Resources.Load.html

[magic panther]

But what I need are specific files of any kind, for now a RuleTile and texture. I don't know what to do, as theyre in separate folders. Some in Graphics > Backgrounds > 00 > 04.png, some in Game > Tilesets > StoneBricks > StoneBricksRuleTile.something (.RULETILE? .asset?)

for example*

[rich adder]

not sure how that changes anything

[magic panther]

I'm unsure how to decide what folders to move to a Resources wrapper

do I include Prefabs? Scripts?

[rich adder]

i personally don't like using it and just go for Serialized references or SO containers.
but generally just whatever you're loading now with AssetDatabase

[untold raptor]

gpt isnt helping me at all rn hence why i came here

[rich adder]

don't post crap AI spews as answers to questions #📖┃code-of-conduct

[magic panther]

I think I share your opinion. How would I go about the SO?

[rich adder]

for example as SO can contain an array of SOs and you just need to keep that 1 SO where you need to access those ruletiles
SOs are good containers for other Asstes, so you only need to reference 1 thing to access multiple Assets

[fair badge]

Try to make wheel collider more inside i had same issue and that helped

[meager gust]

just letting you know the physx wheel colliders (default in unity) are awful garbage. Its difficult getting them working for a 4 wheeled car, let alone a balancing motorcycle

[fair badge]

Otherwise you can use Assets like:Realistic Motorbike Controller

[rich adder]

raycasts are the answer

[meager gust]

@untold raptorYou should look into getting better "wheel colliders" off the asset store, or building your own if you're interested. Building your own is actually pretty simple.

[rich adder]

you just have to juggle creating your own friction

[untold raptor]

oh boy 😄

[meager gust]

A lot of people don't realize that cars in video games are actually just hover crafts 😉

the wheels are 100% visual

[untold raptor]

this has gone from simple drag and drop to create my own physics lol

[meager gust]

nah its not that advanced

[rich adder]

You dont have to make your own physics, just use for example: a raycast to create up and down suspensions instead of relying on wheel col

[untold raptor]

so just scrap the colliders in a whole cos they are trash?

[rich adder]

99% they are trash

[untold raptor]

gotcha

[meager gust]

Yes, basically what navarone is saying.
Send a raycast down from the wheel position. Think of this raycast as a spring. How much is your "spring" actually compressing? (between 0% and 100%)

then just add force upwards

proportional to the "compression" amount

[rich adder]

I have a 2 wheel game but I use 4 rays on that but you can probably force it to only work on 2, I just never bothered

[keen cargo]

alrighty i'm back at it again with the gap issue - i've got some progress with it as now only ONE tile has the flickering gap, and it's always the first tile that gets moved that causes this

another interesting point is that the flickering can only be seen when the tiles are moving

I have checked that the tiles are on the same ordering layer ( having different ordering layers doesn't change anything), and that the Z axis is also the same

I've also tried deleting the tile and putting it back in case i messed something up

here's the code:

using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

public class LevelScroller : MonoBehaviour
{
    public Sprite sprite;
    public Transform[] tiles;
    public float scrollSpeed;
    public float tileHeight;
    public float pixelsPerUnit;

    // Start is called before the first frame update
    private void Start()
    {
        tileHeight = sprite.bounds.size.y;

        for (int i = 1; i < tiles.Length; i++)
        {
            tiles[i].transform.position = new Vector2(tiles[i - 1].transform.position.x, tiles[i - 1].transform.position.y + tileHeight);
        }
    }

    // Update is called once per frame
    void Update()
    {
        for (int i = 0; i < tiles.Length; i++)
        {
            tiles[i].transform.Translate(Vector2.down * Time.deltaTime * scrollSpeed);

            if (tiles[i].transform.position.y < -tileHeight)
            {
                float highestY = GetHighestTileY();
                tiles[i].transform.position = new Vector2(
                    tiles[i].transform.position.x,
                    highestY + tileHeight);
            }
        }
    }

    float GetHighestTileY()
    {
        float highestY = tiles[0].transform.position.y;
        for (int i = 1; i < tiles.Length; i++)
        {
            if (tiles[i].transform.position.y > highestY)
            {
                highestY = tiles[i].transform.position.y;
            }
        }
        return highestY;
    }

}

[untold raptor]

im picking up what your putting down. after the hovercraft analogy, that really helped me understand what i need to do now

[rich adder]

there are multiple good videos on youtube that explain the math behind it

https://www.youtube.com/watch?v=CdPYlj5uZeI&pp=ygURcGh5c2ljcyBjYXIgdW5pdHk%3D
its for car but the same concepts apply

[meager gust]

float springCompression = 1 - (hitDistance / raycastLength);
is basically gonna be the heart of the equation

[rocky canyon]

my man 👊

[rich adder]

such a good vid

[untold raptor]

thanks man

[tribal edge]

Thought you released it on the store, was looking for it

Wait that's not you

Didn't you make a video on a car controller a while back though? Or an asset?

[rocky canyon]

i mean i actively use that tactic

so i approve 👍

[meager gust]

a little bouncy but yeah good example

[rocky canyon]

can even play around with the center of mass

i imagine doing a bike would be relatively easy

esp comparing it to unity's wheel colliders 🤢

[meager gust]

the difficult part about the bike is just keeping it upright

[untold raptor]

honestly making my own wheels sounds kinda fun

[rocky canyon]

i have better.. but yea.. first example i came across on my own.. u can also raycast downwards to place the wheels relative to the ground

[untold raptor]

would u say using a mesh collider better than using any other? (with convex)

[meager gust]

if you sweeptest, you can simulate the actual shape of the wheel 😉

single lined raycasts make icky wheels. <-- afaik the physx implementation does this

[rocky canyon]

oh u want bouncy..

heres some bouncy

[rocky canyon]

true true.. ive thought of doing this once or twice.. and i still might..

but for arcade type stuff 1 ray is plenty

[outer marsh]

hey guys im making a pixelated 2d cool game and im looking for a scripter i curently just made sprites

[rocky canyon]

like in a radius from teh center? or like a half arch from the car?

which would u do?

[meager gust]

gimme a sec ill briefly upload a video

[rocky canyon]

like i could picture two different setups that could work..

[meager gust]

nah, no multiple raycasts

sweeptest is raycasting basically an entire mesh

physx handles it behind the scenes

[rocky canyon]

ohh interesting..

[meager gust]

ill show you how nice this looks one sec

[rich adder]

lol

[rocky canyon]

oh yea, thats noice

[meager gust]

same operation, just sweeptest replaces raycast

[untold raptor]

that suspension flexing is amazing

[meager gust]

I did actually try this also (both examples), but the gaps between the raycasts caused serious issues

you'd need like tens of thousands per wheel to make it viable

[untold raptor]

well i done something wrong here 😂 gotta add some stuff to stop it from turning into an oppressor

[verbal dome]

A low center of mass helps with stabilization

You can manually modify Rigidbody.centerOfMass

[rich adder]

also make sure mass is not like 1 or something, these things are pretty heavy usually and have decent amount of mass

nver had good luck with mass below 1000 with suspensions

[untold raptor]

gotcha

[keen cargo]

bump, tried feeling around the sprite tools too, no dice

[rich adder]

you need PixelPerfect on your camera

[keen cargo]

got that

[verbal dome]

Missing context here

[rich adder]

can you show video of what it looks like

[mint flint]

hi

[keen cargo]

yep, one sec

[mint flint]

im new

[rich adder]

Hi new

[mint flint]

haha no, im GALADIXO

[short hazel]

I'm dad

[keen cargo]

so i have this system where tiles are placed on top of each other to simulate an infinite scrolling level

before i had an issue where each tile placed left a 1 pixel wide gap inbetween the tiles, i got past that except for now this only one tile that leaves a flickering gap

[rich adder]

huh normally the ortho size of camera is grayed out when pixel perfect is active

[keen cargo]

ah it's because the ortho is the same size as the pixel perf

just increased its size

[rich adder]

I mean normally pixel perfect controls the ortho size

[keen cargo]

ahh

[rich adder]

maybe its urp/unity6 thing

[keen cargo]

yeah i could update to unity6 as well

it's currently on 2022 LTS

and everything is backed up on github in case that screws it up

[rich adder]

hmm i think its more to do with using BRIP instead of urp the camera

did you check out the scene view?

does the same thing happen if you zoom in

[keen cargo]

yep

happens both scene & game view

[meager gust]

you should start with a 4 wheeled vehicle until you understand what's happening. It will make the process a lot easier.
Forget having a car model for initial testing. Just use a stretched cube with 4 raycasts (one at each corner)

[keen cargo]

i've also tried sprite atlas, sprite material with the pixel snapping turned on, nothing is changed

one part that i have definitely noticed is when the LateUpdate() is changed to FixedUpdate(), the gap turns larger

but it's ONLY for that tile

you've got to be fucking kidding me

i just fixed it

i just moved the translate part of code after the if function

i mean it MAKES SENSE, since code goes top to bottom, it'd do the translate first and then the if

and since my pc is a good boy, it did the translate + if really fast, making the tile overlap and flicker at that one little point

[swift crag]

Order-of-operations can be very important

within a function, between different objects...

[proper needle]

im 15 and new to unity, why doesn't my key glow

if any1 knows

[knotty hawk]

ngl cuz of color key looks glowing enough for me

[proper needle]

ik but the surrounding area isnt

[rich adder]

probably because you dont have Post Processing or Bloom Cranked up

[proper needle]

idk what that is

[verbal dome]

I think the glow is supposed to come from the Light2D

[proper needle]

i have light 2d

[rich adder]

yeah but post processing should be enabled for urp

check camera component make sure PP is on and you have a Volume with a profile

[proper needle]

i dont understand any of this 💀

[rich adder]

start googling lol

[proper needle]

so i just go to main camera and its in inspector or what

[rich adder]

yes screenshot the Camera component

[proper needle]

is this what ur talking about

[rich adder]

post processing, do you see that checkmark?

[proper needle]

ok i see

do i need anything else

[rich adder]

gameobject with volume component + profile inside

[proper needle]

i went into gameobject

idk if im doing this right

[rich adder]

Volume

[proper needle]

which one do i choose

or just box volume

[rich adder]

Global, sorry

[proper needle]

oh

thanks

[rich adder]

create a new profile make sure you got enough bloom

[proper needle]

where do i do that

[rich adder]

Volume has option to create new profile iirc, then do Add Override -> Bloom (play with threshold and intensity)

[proper needle]

i see

is there anything i missed

my key still doesn't glow

[rich adder]

make sure volumetric is enabled on the light2d

and what is your values for bloom

actually Iirc for 2D lights all you need is the Volumetric option instead of sprites

[proper needle]

that was it

[rich adder]

haha yeah 2D is qirky.. this lighting stuff is new got confused 😅

you still need PostProcessing/bloom for glow in sprites n stuff tho

[proper needle]

alr

thanks

my textures look like this now

any1 know what happened

[rich adder]

did you delete the Global Light 2D?

[proper needle]

idk

[proper needle]

that was what happened

[rich adder]

btw non-code questions in #💻┃unity-talk this a code channel

[proper needle]

alr thanks

[rancid tinsel]

how on earth does OnDestroy() work

I thought I understood it but clearly not

[flat sphinx]

goddamnit now i wanna make a wacky racing game with cars bobbing like that

[swift crag]

testing gameObject != null sounds a bit weird here

The error is happening because you're trying to access the gameObject property of your MonoBehaviour-derived class

Trying to access this property on a destroyed object is invalid

If you really want to know if your own object is valid, you'd do if (this)

[rancid tinsel]

but how can the object be destroyed if im accessing it in OnDestroy()

[rich adder]

cause its marked to destroy

[swift crag]

well it's not OnBeforeDestroy (:

Is this happening as the game exits?

I'm pretty sure that the object only becomes invalid sometime at the end of the frame, normally

But I know that this changes when exiting Play Mode

[rancid tinsel]

i managed to fix it, i think the sounds were parented to the object that was being destroyed

or something like that

[swift crag]

If you destroy a game object, all of its child game objects are also destroyed

[rancid tinsel]

is there no way to "cancel" a destroy btw?

[swift crag]

No.

If you don't want to destroy an object, don't call Destroy on it

[rancid tinsel]

seems weird that all children are just doomed for destruction and cant be unparented or anything

[verbal dome]

You can unparent them before you destroy the parent

[swift crag]

If you want to play an audio clip as a thing is destroyed, consider this..

https://docs.unity3d.com/ScriptReference/AudioSource.PlayClipAtPoint.html

I believe this is 3D-only, since it doesn't let you set the spatial blend

so it would be inappropriate for a 2D game where you don't want to spatialize audio

[rancid tinsel]

i meant like after theyre "marked"

[rancid tinsel]

oh wow thanks, i had no idea that was a thing

[latent glade]

is there a way to have a Bot know what path to a player has no obstacles without Raycast? I know how to use raycast and I have used it a lot, I just want to know if theres another way

[meager gust]

unity has a built in pathfinder

unity ai navigation is navmesh. and it is not less than a month old lmao

[latent glade]

mb the version is less than a month old

[meager gust]

@latent gladehttps://docs.unity3d.com/6000.0/Documentation/ScriptReference/AI.NavMesh.html

if you want to steer rigidbodies, you'll want to extract the path and steer the rigidbody using addforce to each waypoint

[latent glade]

so in a platformer, could I still use linearvelocity for the x value?

[meager gust]

yes, you can steer with velocity

the important part is that you don't natively use the rigidbody as a navmesh agent

because unity will forcefully override it's transform, which bypasses the physics engine

[latent glade]

ok thank you

[slender nymph]

based on this, i'm going to assume this is for 2d. which would mean navmesh does not work for it out of the box, there's a third party asset that will allow navmesh to work with 2d but you'll have to search for it. there's also assets like aron granberg's A* Pathfinding Project which are great for 2d

[latent glade]

Im finding a bunch of tutorials for 2d, is it doesn't work with platformers or it is outdated with 2d or something? Because you would need addforce for jumping and stuff?

[slender nymph]

navmesh does not work with 2d out of the box.

[latent glade]

wdym out of the box? the camera?

[slender nymph]

no, i mean that navmesh does not work with 2d. there are assets that allow it to, but it does not work with 2d by default

[meager gust]

"out of the box" meaning by default, It won't work.

[latent glade]

oh ok

[meager gust]

as in, it only works with 3D 🙂

[latent glade]

Just found it, its $140. What assests would I use to make navmesh work for 2d?

[slender nymph]

you can google it. but there is a free version of that asset

[woven dust]

just make a 2d game in 3d 🧠

[meager gust]

If you want something simple, you could always just make a 3D scene, but still have the camera fixed in place like a normal 2d platformer

"AI" shouldn't be all too difficult for a 2d platformer in the first place tbh

you could probably just make something yourself

[latent glade]

Yeah I was thinking about that

[meager gust]

navmesh is typically for more complex problems. Like a character finding his way out of a room

[latent glade]

Would raycasts be a good way to do it or would that slow the game down too much?

[meager gust]

raycasts aren't a problem for performance unless you're doing tens of thousands of them

[latent glade]

alright sounds good

[grand rose]

what does this mean?

[wintry quarry]

device is an InputFeatureUsage<float> so its TryGetFeatureValue out param will be a float

but you used a bool

i.e. bool isPressed

[swift crag]

you mean CommonUsages.trigger is an InputFeatureUsage<float>?

[wintry quarry]

no

[swift crag]

device is presumably an InputDevice

[wintry quarry]

oh - maybe

[swift crag]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/XR.InputDevice.TryGetFeatureValue.html

[wintry quarry]

I'm not that familiar with XR stuff, I was imagining TrtGetFeatureValue being an extension method with device basically as the first param. But that makes sense too

yeah that makes more sense

Basically this one is being called, but your out param is a bool @grand rose , so it's not happy

or the other way around - it thinks it's the bool version but you provided InputFeatureUsage<float> Either way it's a mismatch.

[swift crag]

yeah, it's trying to figure out some way to coerce the things you provided into something that exists

[grand rose]

i see thanks

[north kiln]

Also, surely !ide

[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
• :question: Other/None

[swift crag]

ah, yes, i didn't notice the missing error in the code editor

[wispy coral]

hey yall im kinda confused that when i create a script it doesnt come with the using System.Collections; and using System.Collections.Generic lines

[wintry quarry]

Depends how you create it. But it really doesn't matter

Those would have come from a file template.

Unity 6's file template doesn't have those

[wispy coral]

Oh i see

[steep rose]

the easiet thing to do is to just add whatever you need when you create it

[wintry quarry]

You can and should be using a fully configured IDE that automatically adds using directives as needed.

[wispy coral]

I was following one of the unity courses and the guy created a script and it came with those

[wintry quarry]

ok, well, it's not important.

But you should really try to use the same version of Unity as the tutorial you are following

or you will see lots of little differences that might confuse you if you are a beginner.

[wispy coral]

which one can i use, im using vscode since i have a really low spec pc but barely enough to run unity

[wintry quarry]

Rider or Visual Studio

Rider is best IMO

[wispy coral]

ill give it a shot

how heavy is it on performance?

[steep rose]

Visual studio is slow

[wintry quarry]

That's a really vague question. Rider is fast, after it does its initial indexing.

[steep rose]

I have not tried rider yet

VSC is pretty fast as well but it all comes down to personal preference

[wispy coral]

alrighty

[steep rose]

choose which IDE you want to use

[wispy coral]

im used to the vscode interface so idk if rider is quite different

also i barely know how to code

[steep rose]

You will learn them over time

[wispy coral]

I see, thanks

also last thing, is rider user friendly?

[steep rose]

you would have to use it to make your own judgement, or look at reviews of it

[wispy coral]

got it thanks

[wintry quarry]

#🏃┃animation not a code question

[sonic hull]

😭

oki, I'll reopst it, tyty

[crisp olive]

/*who knew programming was this much fun

Just learned Prefix (++x) and Postfix (x++) operations Lets goooooooooooooo*/

[vocal urchin]

Is there by chance a quick and easy way to get all Vector3Ints within a circular 2d bounds? 🙂

[wintry quarry]

You could start at center + (-radius, -radius) and do a quick for loop over that rectangular area, checking if each point is within the radius of the circle

[wispy coral]

can you use vscode for commercial gain? im just kinda confused about rider's licensing

[wintry quarry]

Rider is free for non commercial use

paid if for commercial use

VSCode is free

[wispy coral]

lets say i want to release a game on steam for free would that qualify as commercial use?

[wintry quarry]

no

if you don't plan to make money, it is not commercial

[wispy coral]

i see

as long as i dont get monetary benefit from it its fine

nice

[vocal urchin]

awesome. I can just use the Contains method? Thanks for the idea!

[wintry quarry]

The Contains method of what?

[vocal urchin]

I'm seeing that bounds include a contains method

[wintry quarry]

If you mean Bounds, that will not tell you if it's in a circular area.

Bounds is the AABB of the collider

Assuming you're talking about a CircleCollider2D

Basically it's a rectangle

[vocal urchin]

Ahh I could just measure the distance from the radius

center

using the radius

[wintry quarry]

yes

[wispy coral]

im not sure what to use between rider, vs2022 or vscode

[cosmic dagger]

if you can get/use Rider, go for that . . .

[wispy coral]

i like vscode but i dont want to be having problems down the line

[wispy coral]

thats the problem it's a quite heavy IDE and im honestly afraid of the licensing fees

[wintry quarry]

Nothing is going to happen with licensing fees

[teal viper]

You can always switch to another ide🤷‍♂️

[wintry quarry]

Rider has the best Unity integration, that's why I recommend it

[wispy coral]

i see

[teal viper]

I'd just stick with visual studio as a beginner.

[cosmic dagger]

yeah, the integration is ridiculous . . .

[vocal urchin]

got a little circular fog of war going now. thanks praetor!

[wispy coral]

what im curious is that if i keep using vscode that it will be lacking in some aspects

i like the plugins and themes for it

[wintry quarry]

VSCode tends to break with its Unity integration randomly

at least in my experience

and then you waste time trying to figure that out

Also last I checked there was no functional debugger for it.

[wispy coral]

oh dang

is there not a more lightweight version of rider?

[wintry quarry]

At some point, you need to make a choice.

This is your choice to make

[teal viper]

Pretty sure there is. Coming with the C# extension. But yeah, I wouldn't recommend vs code for C#.

[wintry quarry]

we can't make it for you

[wispy coral]

i see

[wintry quarry]

I might be a bit outdated, since I haven't used it in a long time

[wispy coral]

ill go for rider

see how that plays out

thanks so much guys

[wintry quarry]

You can always change later

[wispy coral]

youre right

ill see if my system can handle it with other windows open

and if it can ill keep it

[crisp olive]

fog of war ahhh

[eager spindle]

based on my personal experience vscode is ok, im using it now because my visual studio installer bugged out. just that the autocomplete can be subpar.

in this case it recommends a visual studio namespace before recommending unity's ui namespace

[rich adder]

M comes before U

[cosmic dagger]

i believe that's in alphabetical order . . .

[eager spindle]

if theres a way to remove this namespace from being recommended/prioritising unity's namespaces to be recommended ill gladly take it

[undone depot]

is there an easy way to reset a variable if it remains unchanged for a bit?

[rich adder]

a timer?

[cosmic dagger]

use a timer: once expired, check if the variable has the same value since the timer started, and reset (if true) . . .

[wintry quarry]

reset it to what? If it hasn't changed, doesn't it not need resetting?

basically yes - write a little code.

[cosmic dagger]

i take it you mean, "remains unchanged," after it has been changed, no?

[rich adder]

I think intellicode can figure it out

[undone depot]

yeah, its for a melee combo system
it counts up the number of attacks made and changes the next animation played based on that
it just doesnt reset the number if you stop attacking right now

ill do the timer thing

[wintry quarry]

Basically i'd do something like:

• Make a property to change it which also sets a timer. Only set it through that property so it always sets the timer
• In Update, check if the last change was over some threshold. If so, "reset it".

[regal wing]

Me and a friend are fairly new with Unity, we're trying to make a 2D platforming game
Here we've ran into a problem that we've tried searching for solutions online but haven't managed to find one so far
In the video you can see that there's random audio icons everywhere and the referenced script on the behavior is missing, problem is we don't know what said script is because it's listed as unknown
Does anyone know how to fix this? Thanks (If I chatted in the wrong channel let me know I just joined this server and have read the rules)

[wintry quarry]

The icons are gizmos for the AudioSource component

you can disable them by disabling gizmos in general, or that specific gizmo

As for the warning - check all the objects in your scene and check all your prefabs

one of them will have a broken component on it.

[late abyss]

I don't know how I didn't assign the variable.

I thought I did everything I was supposed to do

It's the audiosource variable GameOver

[rich adder]

show where its assigned

[wintry quarry]

Did you actually assign the variable though?

nothing in your screenshot seems particularly relevant to the error, which is presumably in a different script.

[late abyss]

How id it supposed to look like if I did assign the variable?

[wintry quarry]

Like not saying None in these slots

(this is an example from my game)

Here's how it looks unassigned

Note that you didn't even provide a screenshot of the inspector

[late abyss]

I'm going to have to get back to you later. I was tampering with my own game and now I can't make the bird fly anymore

[austere ice]

thx for the answer mate. but, it still like this. The game and the scene, it like its switched. I've tried to disable the gizmos, it's still happen like this

[regal wing]

Should I make a thread for this btw? To not clog up the channel

[wintry quarry]

Gizmos are still enabled in your screenshot

Disable them with this

[austere ice]

ah i tred it again and it works now.

thanks alot mate

Hey i'm looking for some help with something - if anyone has experience making xcom like games !

[royal lodge]

who can help me?

i need to know how to start a script

please i need someone who can help me

[teal viper]

Create a new script and start it. It's probably the first thing you learn if you !learn properly:

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[royal lodge]

how do i create a script?

[teal viper]

Via the context menu in the project tab. This and a lot of other basics are covered in the beginner pathways on unity !learn. Go and learn properly:

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[royal lodge]

bro 750 hours is to much i can learn it in 3 days by only using it just tell me what to do

[teal viper]

750+ hours is all the content on the platform. Not just the beginner tutorials.

[teal viper]

You're not gonna get much help with such attitude. Show us that you have put some effort.

[royal lodge]

bro huh?????? where can i create a script

[teal viper]

I told you were. Try reading my messages again.

[royal lodge]

type again

[royal lodge]

there is no context

where tf is script?

[teal viper]

Just go and learn properly

[prime goblet]

!learn first, ChatGPT later (super later)

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[prime goblet]

again, you don’t need to do all 750 hours

[gloomy cosmos]

Bruh there's literally an option called create and it's the very first one

[wicked cairn]

Always agreed on that, ChatGPT is a powerful assistant, not the answer. It can do a lot and save you tons of time, but you need to know programming to break down your needs to it.

[flat sphinx]

talk is cheap

[prime goblet]

claims to be learning from ChatGPT
doesn’t know how to do a unity fundamental
isn’t willing to use all the different learning platforms people are redirecting them to

[wicked cairn]

Optimally at least some YouTube videos would help. GPT is a good learning tool but it’s not useful if you don’t know how to navigate unity lol

They will realize that eventually.

Hi，I would like to ask a question, assuming that orange and blue are two UIDocuments, and their Panel is the same. I now want to place the blue one at the bottom of the screen. How should I do it?

orange is startup and blue is dialog

[frail hawk]

probably a question for #📲┃ui-ux or #🧰┃ui-toolkit

[silent falcon]

Thank you, I will go to the corresponding group to ask.

[lyric rapids]

Hi, I can't understand what causes my game to freeze.
I followed this tutorial https://www.youtube.com/watch?v=QTSWm1RsvzY and as far as I can tell I have everything exactly the same.
As I read online if I enter infinite loop whole editor should freeze, that's not the case.
I also don't get any errors in the console (well, I was getting one, people online said it was due to the lack of subscription to the Unity Version Control so I deleted this package completely but it didn't solve anything)
Here is my code: https://paste.ofcode.org/cfHdGctDZqyMFwMeWtjAM2
If smoothTransition is true, then my character moves by .20 (instead of 1) or rotates by 10 (instead of 90)

It works as expected if smoothTransition is false

[rocky canyon]

use the profiler and see if anything is running wild

i dont see anything in code that could freeze anything..
test to see if its actually freezing?
debug.log in the update for example would be a really simple indicator

[languid spire]

my guess, you are missing an else here

            if (targetRotation.y > 270f && targetPosition.y < 360f)
            {
                targetRotation.y = 0f;
            }
            if (targetRotation.y < 270f && targetPosition.y > 0f)
            {
                targetRotation.y = 270f;
            }

without it the code makes no sense

[rocky canyon]

ohh true!! if those conflict w/ each other or toggle back and forth. the logic might be stuck in an endless update loop..

[frail hawk]

the if (true) triggers me

[rocky canyon]

(not technically frozen) but just not doing anything useful lol

if (targetRotation.y > 270f && targetPosition.y < 360f)
{
    targetRotation.y = 0f;
}
else if (targetRotation.y < 270f && targetPosition.y > 0f)
{
    targetRotation.y = 270f;
}``` throw an else in there

that way only 1 of those can be true at a time

[lyric rapids]

So far I'm following tutorial, there will be collision logic as soon as I fix my current problem

[frail hawk]

then at least use a variable there.

[lyric rapids]

Sadly not the case, these don't affect the movement yet it won't work as well

[rocky canyon]

if(eventually){
}```

its still an issue..

• targetRotation.y > 270f && targetPosition.y < 360f is true, so targetRotation.y is set to 0f.
• Now, targetRotation.y < 270f && targetPosition.y > 0f is true, so targetRotation.y is set to 270f.

brrrrrrrrrrrr

[languid spire]

read your code. if the first if is true then the second will be as well so rotation.y will always be 270

[lyric rapids]

ye noticed it, changed to

if (targetRotation.y > 270f && targetPosition.y < 361f)
            {
                targetRotation.y = 0f;
            }
            else if (targetPosition.y < 0f)
            {
                targetRotation.y = 270f;
            }

[rocky canyon]

just one less thing u have to worry about

[naive pawn]

what's with the 361 there?

[languid spire]

also add some debugging

[naive pawn]

do you perhaps mean <= 360 instead?

[rocky canyon]

tomato tomato?

[naive pawn]

not for floats

[rocky canyon]

ahh tru tru

[lyric rapids]

ye he right but still not the actual problem, its something in here but can't understand what

transform.position = Vector3.MoveTowards(
                    transform.position,
                    targetPosition,
                    Time.deltaTime * transitionSpeed
                );
                transform.rotation = Quaternion.RotateTowards(
                    transform.rotation,
                    Quaternion.Euler(targetRotation),
                    Time.deltaTime * transitionRotationSpeed
                );

[naive pawn]

i mean of course it is since that's the part that will differ between smoothTransition on/off

[rocky canyon]

what if u used a little margin of error? b/c it could be that it never really reaches the target?

if (Vector3.Distance(transform.position, targetPosition) < 0.01f)
    transform.position = targetPosition;
else
    transform.position = Vector3.MoveTowards(
        transform.position,
        targetPosition,
        Time.deltaTime * transitionSpeed
    );

if (Quaternion.Angle(transform.rotation, Quaternion.Euler(targetRotation)) < 0.01f)
    transform.rotation = Quaternion.Euler(targetRotation);
else
    transform.rotation = Quaternion.RotateTowards(
        transform.rotation,
        Quaternion.Euler(targetRotation),
        Time.deltaTime * transitionRotationSpeed
    );``` something like this

[lyric rapids]

Will see gimme a moment

[rocky canyon]

would snap it to the desired positon and rotation when its close enuff

[steep rose]

does unity hang or is it just that nothing is happening?

[naive pawn]

MoveTowards and RotateTowards should handle that fine

this isn't SmoothDamp that asymptotes

[rocky canyon]

or Lerp or Slerp

im just spitballing.. as theres nothing really i see in there that would cause a "Freeze"

[naive pawn]

try commenting one out, and then the other, to see if they work individually, maybe.

[lyric rapids]

Character moves for 0.2 instead of 1, then its unresponsive, unity works as expected, game doesnt

[rocky canyon]

lol.. thats usually the case 😅

[naive pawn]

how is targetGridPos set?

[rocky canyon]

so its not unity freezing.. its:

the character becomes unresponsive after a brief moment

[steep rose]

where is your targetposition and rotation if any?

[lyric rapids]

As I read online if I enter infinite loop whole editor should freeze, that's not the case.
From my original message, could be more descriptive tho ur right

[naive pawn]

they're set in MovePlayer

[naive pawn]

@lyric rapids?

[lyric rapids]

https://paste.ofcode.org/cfHdGctDZqyMFwMeWtjAM2

[steep rose]

you should probably send the entire script

[lyric rapids]

Ye Im doiing it rn

https://paste.ofcode.org/p42uuBpEX7paXqyeD7YDRh

[lyric rapids]

When I did:

// transform.position = Vector3.MoveTowards(
                //     transform.position,
                //     targetPosition,
                //     Time.deltaTime * transitionSpeed
                // );
                transform.rotation = Quaternion.RotateTowards(
                    transform.rotation,
                    Quaternion.Euler(targetRotation),
                    Time.deltaTime * transitionRotationSpeed
                );

Nothing worked, maybe there is some functionality depricated

[rocky canyon]

nope, all thats still relevant

[naive pawn]

well ok you should probably debug AtRest

[steep rose]

also your IDE will tell you if something is deprecated

[naive pawn]

and also targetGridPos

btw, why are you doing this in FixedUpdate?

would probably make more sense to do this in Update

[steep rose]

I was wondering that too

[naive pawn]

sidenote: in AtRest, you can just return the boolean instead of checking if the boolean is true then returning true

[lyric rapids]

I'm a web dev who got assigned to make a game for university, I'm making buttons on the website go jumpy when u hover over them n give u directions on google maps to nearest pizza hut, its my first time with unity so i'm following tutorial

[naive pawn]

- if (x)
- {
-     return true;
- }
- else
- {
-     return false;
- }
+ return x;

[naive pawn]

..uh, ok? i have no idea how this is relevant to my question lmao

[lyric rapids]

Csharpier is shouting at me whole time for syntax, not using braces etc

[naive pawn]

there's no relevant braces when you return a bool

[lyric rapids]

Im following tutorial 1 to 1 and it still doesnt work, trying all i got, not trying to understand it

[naive pawn]

you should start trying to understand the logic

[lyric rapids]

I read thru that code, after it stopped working I tried to get whatever author of the tutorial had

[naive pawn]

and debug where the logic stops working

[sage mirage]

Hey, guys! I would like to know how to enable and disable my cursor when pausing and unpausing the game?

[burnt vapor]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Cursor-visible.html

[sage mirage]

Yeah ok but by default when I am entering the game the pointer is enabled right?

[burnt vapor]

Yes

[naive pawn]

you could set it on awake/start on some central script

[burnt vapor]

This one also applies: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/CursorLockMode.html

[sage mirage]

I have here an issue you know when I am pressing escape button to resume the game I still view my pointer

[burnt vapor]

Okay, so the question is not specifically about disabling the cursor then

In the Unity editor pressing escape enables the pointer again. In build mode this behaviour doesn't exist

Something about not locking yourself out

[sage mirage]

Yes basically it is a different question

So, in the editor it is enabled everytime?

[burnt vapor]

If you press escape

[sage mirage]

I mean even if I resume the game yes

[burnt vapor]

I don't know if this behaviour can be changed

You can implement behaviour around this so it works properly in editor mode, but note in a build this is different

[sage mirage]

CursorLockMode.Locked also hides the hardware cursor. However, the cursor is only locked and hidden after you click in the Game view.

I can't really understand how this behave?

I mean locked and confined

I mean I see nothing in Game View

oh wait give me a sec

Yes I have tried them all but didn't notice the difference

The only thing that I have noticed is that when I have it Locked I can't interact with my UI buttons and anything in the game view but when it's none I can

[zenith cypress]

Locked: locks to center of screen
Confined: keeps cursor in the window
None: Isn't locked and isn't confined

[sage mirage]

So, when do I have to use those 3?

I mean when I want the cursor to be enabled then I am using none but when I want it to be disabled then locked?

I am going to test it right now

[flat sphinx]

how do i move an object programatically
first thought was obj.transform.position.Set(...) but that doesnt seem t owork

scrap that im being stupid

[frail hawk]

transform.position = new Vector3

[flat sphinx]

already fixed it

[frail hawk]

but it depends what you want, if you want physics you would not use that

[flat sphinx]

my issue was that i was setting it to itself

[rough hollow]

hey all working on a top down rpg game and cant figure out why my tiles are like making weird black lines when i am moving.. is this my pc issue or something else?

pay attention to the pond and the top of one of the trees

its like making lines in between my tiles

also not sure why the fps dropped a little bit into the recording (sorry)

[zenith cypress]

Locked to center of screen + hidden -> Doom, Skyrim, any fps game really

Constrained + visible -> Civilization V, Path of Exile (it's a toggle here)

None + either visibility -> Random indie game off itch where you accidentally keep clicking other apps

[flat sphinx]

does setting position not affect children

[rich adder]

ofc it does

[flat sphinx]

it doesnt for me
n not sure what im fucking up

[rich adder]

show setup

[flat sphinx]

                var old = map.gameObject.transform.position;
                old.Set(old.x, old.y + 2, old.z);

debug code

doesnt seem like the map is moving

probably am missing something obvious but am too tired to tell

[rich adder]

do you know what Set does?

[verbal dome]

You are modifying a struct in place

[rich adder]

why are you using that

[flat sphinx]

ah

[flat sphinx]

[rich adder]

modified structs don't do anything lol

[flat sphinx]

im just doing what the holy editor tells me to do

[rich adder]

which one? I dont think i ever seen Set being used on V3 lol

[verbal dome]

You can do this, just gotta assign it back to transform.position

[flat sphinx]

vsc?

[rich adder]

youcan do

var old = map.gameObject.transform.position;
old.y += 2;
theThing.position = old``` btw

[flat sphinx]

yeh tryin to rn

[verbal dome]

Though you could just do transform.Translate(0, 2, 0, Space.World)

[flat sphinx]

OH SO += WORKS BUT ASSIGNMENT DOESNT

[verbal dome]

Or transform.position += Vector2.up * 2

[flat sphinx]

no nvm it doesnt lol

cannot modify the return value of 'Transform.position' because it is not a variable

[rich adder]

you're modifying the copy not the property which is usually the error

[flat sphinx]

ah im still doing it inplace nv,

[rich adder]

position.y returns a property

so you cannot modify it directly

[flat sphinx]

so

                var old = map.gameObject.transform.position;
                old.y += 2;
                map.gameObject.transform.position = old;
```?

[rich adder]

its like trying to modify a method

yes but do you know why?

cause you're just changing the copy first

structs are copies

[flat sphinx]

yeah i do

had to do the same stuff with transform matrices back on [cursed engine]

[naive pawn]

+= is assignment lol

[flat sphinx]

obj.transform = obj.transform.Scale(1, 2)

[rich adder]

yup thats just doing old.y = old.y + 2

[verbal dome]

Yeah a += b equals a = a + b

[flat sphinx]

ermmm technically you can implement one and not the other htrough operator overloading 🤓

[verbal dome]

Can't overload operators on existing types though 🤓

[naive pawn]

+= still is assignment
it's literally called addition assignment

[flat sphinx]

i cant, whos to say someone else didnt

[naive pawn]

also, += can't be overloaded

[flat sphinx]

can it not?

[naive pawn]

assignment operators can't be overloaded in general

[rich adder]

there is slight difference ig.
reason+= events since they are immutable and cannot be assigned with =

[flat sphinx]

well this engine is suddenly 90% better

[naive pawn]

this has nothing to do with the engine lol

[flat sphinx]

language

w/e

[verbal dome]

I did recently see some C++ livestream where the programmer had to separately implement -=, += even after implementing + and -

(I think it was c++)

[flat sphinx]

yup

newer versions at least added <=>

i personally steer clear of overloads in general, never results in anyhting clean

math stuff is typically already implemented for me

[verbal dome]

I don't think I ever needed to use them either

[flat sphinx]

you dont
its pure syntactic sugar

same as properties

nothing you cant do with either of those that you cant through regular functions

[naive pawn]

i mean everything is just syntactic sugar for machine code

[verbal dome]

I mean if I had like structs that I need to + then I would implement it

[flat sphinx]

give a non-math example

[naive pawn]

you never need to + stuff though, you could just Add

[naive pawn]

strings.

[verbal dome]

I didn't mention non-math

But yeah strings come to mind, its builtin tho

[flat sphinx]

obfuscating that its secretly immutable array access also that stuff is builtin

[naive pawn]

for example, sets in c++ use < to compare values
so you can overload < to define a sorting for the set
java doesn't have operator overloads, and instead uses an interface, Comparable, to define a method, compareTo, used for the same purpose

[naive pawn]

stuff involving strings, not just string itself

for example, adding 2 stringbuilders together

[flat sphinx]

that sounds like more builtin stuff

i guess you could argue for that in cpp land where everything is stapled on top of c

[naive pawn]

by "builtin" here do you mean builtin to the stdlib or to the language

[flat sphinx]

but you already have "" as a core part of the lang here (i think)

[naive pawn]

but either way, you might make your own string-based stuff and want to concatenate them without having to do "" + first because that's more expensive

[flat sphinx]

if you're worried about string operations being too slow you would probably also not want to abstract what you-strings are

[naive pawn]

i have no idea what you're trying to say there

[flat sphinx]

use an array and make resizing explicit

[naive pawn]

no that's not what im talking about lol

[flat sphinx]

thats the only means i can think to make strings more efficient

[naive pawn]

im not talking about making your own strings

[flat sphinx]

hten what do u mean a string builder

[naive pawn]

i mean making stuff that's based on the concept of strings

[flat sphinx]

oh

[naive pawn]

that's a separate line of thought lol

[flat sphinx]

json and such?

[naive pawn]

uhh no?

like for example you wanted to make format strings, new FormatString("This is a number: %-3d") or something
and internally it was parsed in the constructor, breaking the string up into a list of nodes
then you could overload + to combine format strings by extending the internal list instead of having to reparse a new format string

[flat sphinx]

what i read was you might make your own string-based stuff and want to concatenate them without having to do "" + first because that's more expensive
reasoned tha tyou meant "make strings more efficient" and by extension "doing your own string stuff"

[naive pawn]

no lol

[flat sphinx]

rip then lol

[naive pawn]

"" + might be unreasonably expensive for cases where you have an internal format that would easily make it more efficient
but like, the structure/overload doesn't have to specifically be for string efficiency

[naive pawn]

like in this case if you didn't overload + you would have to do, say, new FormatString("" + fs1 + fs2), reparsing the whole thing

[flat sphinx]

so handling of FormatString("hi this is") + FormatString("bob") ?

[naive pawn]

yeah

[flat sphinx]

ah

[naive pawn]

just to recap; you of course, don't need the overload, but given its contextual usage, an overload makes a lot of sense

[tiny vault]

Hey guys, i have this field in an SO. public Transform[] teleportTarget; im trying to assign an empty gameObject to it, but all of a sudden it says type mismatch. If i then click the field and press delete, i can assign the empty gameObject, but it's deleted automatically whenever i run the game. Has anyone experienced something similar? And sorry if im in the wrong channel!

[swift crag]

You can't reference scene objects from an asset.

The resulting error is not very intuitive

[frosty field]

alright so i have this script: https://hatebin.com/mnzewoicug
and the thing is, that it works perfectly (except moving camera up and down but i dont care about it right now)
but unity suggest me to use Quaternion.Euler instead of EulerRotation and when i use just Euler for some reason rotatating on left and right doesnt work anymore, i just want to understand why

[swift crag]

did you read the warning message?

[naive pawn]

why not make the camera a child of the player so you don't have to manage the position and yaw separately

[frosty field]

yeah but what does that mean

[swift crag]

it uses radians instead of degrees

these are two different units

2pi radians is a full circle; 360 degrees is a full circle

Also, this entire thing is bogus

Quaternion.EulerRotation(player.transform.rotation.x, player.transform.rotation.y, player.transform.rotation.z);

rotation.x is not your x-axis rotation in degrees (or in radians, or in anything else)

It's the X component of a quaternion (which has four values -- X/Y/Z/W)

It might have happened to work in some situations

[naive pawn]

also you could just transform.rotation = player.transform.rotation;

[swift crag]

yes, that's all you need to do to copy the player's rotation

[naive pawn]

but also with this you could just not have to copy it at all

really you'd need to copy the player's yaw only

ie, the rotation about the y axis

[frosty field]

yeah, that's why i did on the beginning but i wanted to make that moving camera up and down works so i changed it to quaternion and it confused me

[naive pawn]

so transform.rotation = Quaternion.Euler(0, player.transform.eulerAngles.y, 0), i think?

[naive pawn]

(or just do this to have yaw done automatically)

[swift crag]

This would work, yes

[flat sphinx]

i assume unity doesnt have such functions as "get the initial position of an object/state of a variable"

? ,

[rocky canyon]

var grabStartPosition = thing.transform.position

[naive pawn]

what, just reversing assignments?

that wouldn't work in general, no

[swift crag]

I wouldn't expect it to!

[flat sphinx]

as in getting hte state of the variable you set in the editor/have defined in code

[swift crag]

Serialized properties are applied to the object when it gets created

[naive pawn]

prior to pressing play? no i don't believe there's any mechanism to do so

[flat sphinx]

never used a non-shit lang, explain

[swift crag]

this isn't a C# thing

[naive pawn]

and it'd waste 2x the memory for something rarely used

[swift crag]

drag a prefab into a text editor and you'll see a bunch of YAML

[flat sphinx]

depending on the implementation

[swift crag]

this is all of the serialized data for that object

[naive pawn]

no, it would not depend on the implementation

[flat sphinx]

o ,

[swift crag]

unity applies it during object creation

[frosty field]

that did worked, thank you a lot. I just didnt understood the euler right

[swift crag]

I guess you could look at the values on the prefab, if you're using prefabs

But Unity isn't going to hang on to the data it applied during object creation

[flat sphinx]

if you designed a lang around lazyiniting vars adding initial() wouldnt be wasting memory
but thats besides th epoint which is why i tilda'd that comment

[naive pawn]

no that's not how any of it works lol

if you want to both have the current and a previous value, you have to store both of them. simple as that. if you don't want to store them in memory, it's gotta be in storage, and you have to pull that storage back into memory later anyways

[rocky canyon]

is this still a continuation of array vs json?

[swift crag]

no

[flat sphinx]

no we just love arguing with eachother

[flat sphinx]

i meant in that sort of lang adding initial() wouldnt be wasting any more memory

[swift crag]

this seems irrelevant

[naive pawn]

...because you already waste it?

[flat sphinx]

it is

[flat sphinx]

yes

[naive pawn]

how is this a valid argument at all lmao

"the engine wouldn't waste it because the interpreter would be wasting it instead"

[flat sphinx]

how is this a valid argument for validifying these for unity? its not lol

[naive pawn]

alright i have no idea what you're even saying anymore 😂

[flat sphinx]

good

lets drop it

[naive pawn]

unity uses a sane language that doesn't use more memory than it needs to, and doesn't waste memory itself, so it doesn't have that feature

[flat sphinx]

we shat up #💻┃code-beginner enough for today, lets continue tomorrow

: 3

[naive pawn]

what is it with you trying to make ridiculous points that have absolutely no basis lmao
seems like you just irrationally dislike c#/unity and you're looking for any excuse to shit on it for stuff that it's doing right 😂
why are you even here lmfao

[tiny vault]

Thank you so fking much!

[flat sphinx]

? ,

this convo isnt me shitting on unity
just asking if it has a feature im accustomed to

which i already assumed in advance it doesnt

[swift crag]

to answer the original question: you generally record initial state in Awake or Start

Awake is appropriate if you want to grab the value immediately after object creation (literally before the Instantiate call returns)

[naive pawn]

what kind of shit language has this behavior lmao

[flat sphinx]

one that makes all variables unalloc'd by default and retrieved from a prototype when accessed (so that stupids [which its trying to pander to] dont blow up their game by throwing a ton of variables on the base class)

but again

wildly off topi

c c

[naive pawn]

doesn't answer my question tho lol

[flat sphinx]

: 3

refer to the last comment

[naive pawn]

what, this?

: 3

[swift crag]

consider moving on

[flat sphinx]

^ ^

[naive pawn]

im just curious what language has this behavior now lmao
since lemons can't bear to mention the name, im convinced they're just bs'ing at this point 😂

[flat sphinx]

if you say so :3

[steep rose]

it's not worth the argument that will occur from going further in the conversation

[naive pawn]

i mean, if i just got an answer to this, i'd be done with the topic, but well, look at how long it's gone

[swift crag]

Consider moving on.

[nimble mortar]

Lets say I have a tilemap like this, what are different method I could use in order to connect the different section dynamically in code?

I would want to make sure I am connecting sections that are within a certain distance of each other and support rigid (straight lines / 90 degree angles) and more organic looking corridors.

[swift crag]

I'm confused by the example.

Is this six pre-defined spaces with a couple of obstacles in each one?

which you want to link together?

[nimble mortar]

yea, I am trying to figure out how I could connect these currently disconnect area in a tilemap dynamically

[fickle plume]

Just think what you want it to do and break it down to simple tasks. Treat each island as single array collection.
Find nearest island.
Find closest tiles to each other.
Start creating tiles in the nearest direction from them.
Create more tiles around each to create a "bridge volume"

[severe onyx]

is there a way to detect a collision between two objects with BoxCollider2D components if I'm moving one of them via transform.Translate? or do I have to use a rigidbody and move it with that?

[naive pawn]

one of them needs to have a rigidbody to handle the physics

[severe onyx]

one of them does but it's not the one Im moving

[naive pawn]

doesn't specifically matter how they're moved, though moving via transform on a GO with a rigidbody could cause problems

[naive pawn]

then there shouldn't be any issues there

just gotta make sure they fix the collision matrix

https://unity.huh.how/physics-messages/collision-matrix-2d

[severe onyx]

these are the relevant components on the static and moving object respectively

[naive pawn]

a static rb doesn't itself trigger collisions

[severe onyx]

but OnCollisionEnter2D doesnt trigger when they overlap

[naive pawn]

you need a dynamic rb on one of the objects

[severe onyx]

oh I see

yup, now it works

ty

I dont really understand the purpose of a rigidbody on an object that never moves

[naive pawn]

yeah it might not really make sense to have that?

is the other object, without the rb, the player?

generally that's what's given the dynamic rb

then stuff like walls won't need rbs

[severe onyx]

nah it's a projectile

but I guess it makes sense to give that one the RB then

[naive pawn]

sure that'd work yeah

[severe onyx]

the other objects are the level constraints (invisible walls)

I thought I needed the RB on them to make sure they physically block the player moving through them

[naive pawn]

you could then set a velocity on the rb, set low linear drag, and just, literally fire and forget lol

[severe onyx]

I was worried about performance when there's dozens of projectiles on screen at once I suppose

[severe onyx]

confirmed that that was never the case and I was just being silly oops

[swift crag]

You put a rigidbody on something to tell the physics system that it's going to be moving around

[steep rose]

pool them

[swift crag]

I wouldn't even think about performance right now

a few dozen projectiles?

[severe onyx]

they despawn when leaving the visible area anyways so

or on hitting something, duh

[swift crag]

even if you spawn and destroy these very rapidly, it's not going to be particularly bad

[naive pawn]

computers are really fast. don't worry too much about optimization at this stage, worry about it when it becomes a problem

[steep rose]

as long as that area is not huge and there are not hundreds of them you probably are fine

[swift crag]

Pooling is a good idea for when you have a very large number of projectiles, where the overhead of creating and destroying all of those objects gets noticeable

[steep rose]

if you need an abundance of projectiles you should most likely pool them

[severe onyx]

fair enough. just trying to be a bit more diligent about efficiency tha I usually am lol

[swift crag]

(you just recycle the same bullet objects)

[severe onyx]

aye, will look into that as well, ty

[steep rose]

depends on the computer

[naive pawn]

computers in general are fast

it really doesn't depend when the lower end of the scale is still in MHz

[severe onyx]

I mean anything even remotely measured in MHz does a silly amount of operations per second

[naive pawn]

i don't think anyone is gonna expect to run 3d games smoothly in kHz amounts of operations

[severe onyx]

this is a 2d game anyways

[naive pawn]

ah. definitely crossed wires lol, whoops.

yeah even less to worry about, then

[severe onyx]

I'll make sure to report back and blame you specifically if it ever runs choppily 😌

[naive pawn]

a drop in the bucket of me blaming all the problems in my own game on myself lol

[severe onyx]

jokes aside, thanks for the help

more than anything this is an exercise for me to explore all these questions and discover best practices

[fickle plume]

You don't need rigidbody on a stationary object. But it you want to have something like moving platform it has to have one if you want for physics to interact properly. Because you would need to move it with Rigidbody2D.MovePosition.

[severe onyx]

to get a similar effect of using transform.Translate((some direction vector)) would I use Rigidbody2D.MovePosition(currentposition + direction vector)? or is there some neater way to do that?

[severe onyx]

wait this was already answered for my use case by this, wasnt it

[naive pawn]

yeah

[severe onyx]

I swear I can read

[naive pawn]

could use AddForce

[steep rose]

even if you wanted to use translation, it would cause unreliable collisions when using a rigidbody

[naive pawn]

and then you would multiply a normalized direction vector by a given magnitude
there was a similar convo, it was either impulse or velocitychange

impulse would be mass-dependent, velocitychange would not

[steep rose]

so it's much better to use one of the physics methods for it

[severe onyx]

gotcha. physics stuff seemed overkill for what Im trying to do because I dont have any gravity or anything like that acting on it, but I suppose it makes sense for collision detection purposes

[naive pawn]

if the mass of the bullet doesn't matter (and is set to 1) then both would have the same effect, but you might want to use the bullet mass for stuff like, recoil or knockback, idk

[fickle plume]

Yes, don't forget to use it in FixedUpdate as well

[severe onyx]

I've been wondering a lot about Update vs FixedUpdate

FixedUpdate is recommended for stuff that needs to happen at a consistent real time frame regardless of the framerate, is that the idea?

[naive pawn]

right

Update = frame
FixedUpdate = physics tick

[steep rose]

use any rigidbody/physics based methods in it as it produces better results

[naive pawn]

and FixedUpdate has a specified tick rate that it'll process physics stuff by

[steep rose]

and is not framerate dependant

[severe onyx]

I remember learning to multiply stuff with time.deltatime way back in the day to account for framerate differences but this is discouraged for a bunch of reasons I take it?

[naive pawn]

no, that's fine

it's just more about, what makes sense where

[steep rose]

you shouldn't do time.deltatime in rigidbody (i.e addforce) methods as it does it already but in general it's fine

[severe onyx]

gotcha

[naive pawn]

uh no not quite

[real grail]

Good rule of thumb if you are messing with physics components like rigibody. Run it on FixedUpdate and do Time.fixedDeltatime.

[prime goblet]

you don't need that either

[severe onyx]

50hz is the standard polling for FixedUpdate yeah? and presumably this should be sufficient even for fast paced 2d games?

[steep rose]

well yes those methods do time.deltatime already no?

[naive pawn]

some stuff in rb methods are inherently time-dependent, so they do stuff basd on physics ticks
but not all of rb methods are time-dependent

[prime goblet]

all physics uses fixed physics generally i think

[fickle plume]

FixedUpdate is already using fixed frames you don't need to add delta

[steep rose]

and this

[naive pawn]

MovePosition, for example, just does the move in the next tick, so if you're using that as a replacement for transform.Translate, then you would add a time component to that

(or, i mean, you'd use MoveTowards.)

[fickle plume]

You would use Time.fixedDeltatime inside a coroutine that awaits fixed frames and you need to get that time frame, for example.

[severe onyx]

I ended up going with the velocity approach for the projectiles for now either way

assuming all the internal logic still happens on fixedupdate ticks but it is indeed nice to just "fire and forget"

[naive pawn]

rb.MovePosition(Vector2.MoveTowards(transform.position, target, speed * Time.deltaTime));

[steep rose]

well I was mainly talking about the addforce, velocity methods for example because moveposition is practically translation but complies with the rigidbodys interpolation for kinematic bodies right?

[naive pawn]

i mean, idk what you meant to talk about, since "rb methods" does encompass moveposition and friends

[steep rose]

ah right, I should have been more specific

[cold pier]

Hello everyone,
I start to create games and here’s my problem.

Every time I transfer my image and they cut them in 16x16 or 32x32 for example. I create my Palette then I insert and the images are small in the grid ( I'm french)

[naive pawn]

set the pixels per unit option in the asset importer

(not a code question)

[slender nymph]

not a code question. bu tyou need to adjust the pixels per unit in the texture import settings

[cold pier]

I'm sorry

[slender nymph]

dang i was too slow lol

[cold pier]

Have a nice night and thank you

[wispy coral]

hey yall how do i make code thats not a bunch of if statements

is it just practice and more knowledge?

[slender nymph]

also don't be scared of if statements. they are perfectly fine

[wispy coral]

nice

thanks

you can research guard clauses if you want

thats a p easy way to deshittify your code

[polar acorn]

Something on that line is null but you're trying to use it anyway

What line has the error

[faint osprey]

Debug.Log(shopRT.position.x);

im debugging my position in update just to check stuff and its not showing correctly to what it is in the inspector and i dont know why this is

it says my x position is -8.5

but in the inspector

its 33 for some reason

[swift crag]

That's because position is your world-space position

The inspector is showing you a local-space position

This isn't anything specific to a RectTransform, mind you

you'd see similar things with a regular Transform

Your local-space position is where you are relative to your parent. If you have no parent, then it matches your world-space position

[faint osprey]

if i change it to localposition.x

it says -927

which still isnt 33 tho

[swift crag]

Ah, the other issue is that this is anchored to the left side of its parent

you could check if this is why by anchoring it to the center and setting Pos X to 0

I'd expect a local position of zero, then

[swift crag]

I believe the inspector is showing you the anchored position

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/RectTransform-anchoredPosition.html

It's 33 units to the right of its anchor, but that's quite a few units to the left of the parent Transform

[faint osprey]

thank you that makes a lot of sense

[real grail]

Try this myb:

public class Clone_Skill : Skill
{
    [SerializeField] private GameObject clonePrefab;

    public void CreateClone(Transform _clonePosition)
    {
        GameObject newClone = Instantiate(clonePrefab);

        Clone_Skill_Controller _controller = newClone.GetComponent<Clone_Skill_Controller>();
        _controller.SetupClone(_clonePosition);
    }
}
