[dusky tusk]

ok im using rigid body now but it cant move on the ground now

like there is a velocity on the x axis but its like 0.6, and i cant seem to see the body moving

it moves fine when im not on the ground though

[teal viper]

Might want to provide more details. Start from a video of the issue.

As well as the relevant code.

[dusky tusk]

i cant record but i can show you my code

i might just rewrite my code lol

are there any resources about platformer movements but instead of jumping, its jetpacks ?

[queen adder]

you can simply just change your jump code to add acceleration instead of force when you jump, and change the getkeydown to getkey

[warm sleet]

Hello, I need some advice, I´m doing a 2D game and Im not sure if I should create the objects when I need them or should I create them when loading the game, and later on set them active or not, for example, I have an enemy pool where I have all the enemies but I don´t know if that would work for when the turrets shoot , does the performance of the game may variate if I create them or if I just set them acrive or not?

[fossil drum]

does the performance of the game may variate if I create them or if I just set them acrive or not?
Yeah, Instantiating is somewhat expensive, that's why you usually use Pools for things you need to instantiate and destroy a lot: https://docs.unity3d.com/ScriptReference/Pool.ObjectPool_1.html
https://learn.unity.com/tutorial/introduction-to-object-pooling#

[warm sleet]

Thanks, I have the pool system done, but I made It following a tutorial and don´t know how to update it for each Tower, I will read the docs and lets see if I can make it

[mellow elbow]

Is it possible for me to loop a coroutine until a certain condition has been met?

[keen dew]

Yes, that is the most common use for coroutines

[mellow elbow]

ohh lol

[spiral rain]

Anyone

[modest dust]

Where's the question?

[spiral rain]

I’ll repost

[modest dust]

You didn't really describe what your issue even is

[mellow elbow]

you didnt ask a question you just said you were making it

what do you need help with

[odd mason]

is there a better way to check if hte player is on ground reliably? im using this and idk if i just suck at values or smthn but its like not working properly, what is ground is a layer mask btw

[spiral rain]

Oh my bad I need help with making it

[swift crag]

well, what have you tried?

[swift crag]

Are you using 2D or 3D physics?

[spiral rain]

Nothing I am not quite sure how to make it

[swift crag]

This will only detect 3D colliders

[odd mason]

3d physics

[swift crag]

I would raise the raycast's origin a bit

I believe raycasts ignore colliders that they start inside of

[odd mason]

k, ill try that out, thanks

[neon marsh]

hi i have a question. Why is my NavMeshSurface not working?

ive been trying to do Monster AI lately

[swift crag]

what does "not working" mean?

[neon marsh]

idk

[swift crag]

then how am I supposed to help you?

[neon marsh]

not showing this like

blue

area

but yea i dont know how to set it up

[swift crag]

show me the inspector for your NavMeshSurface component

[neon marsh]

yea

[swift crag]

Also unfold the "Object Collection" and "Advanced" sections

i forgot those were collapsed by default

also, can you share that in #🤖┃ai-navigation ? that'll be a more relevant place

[neon marsh]

yea

[odd mason]

for some reason chaning my collider to capsule seamed to help aswell as doing what you said

thanks for the help! works perfect now

[mellow elbow]

How do I loop a coroutine until a certain condition is met

[rich adder]

while loop?

[mellow elbow]

I know it has something to do with that, but I dont know where to place the while loop
and should the while loop be activating the coroutine or the code while it is inside the coroutine

[swift crag]

if you want to make a coroutine repeatedly do something until a condition is met, put a while loop in the coroutine

If you want to run the loop once per frame, then you must yield return null; somewhere in the loop

[rich adder]

 IEnumerator SomeRoutine()
    {
        while (SomeCondition)
        {
            yield return null;
        }
        //condition done
    }```

[fossil drum]

Or WaitUntil https://docs.unity3d.com/ScriptReference/WaitUntil.html
Seems to satisfy his needs too.

[swift crag]

WaitUntil is ideal if you just want to...wait, yeah

[mellow elbow]

ok so in theory it should just do the while loop till the condition is true

[rich adder]

if you want inverse use ! then or use WaitUntil like suggested

[mellow elbow]

I was already doing this but it bugged out but it fixed itself for some reason

Thanks for the help

[swift crag]

what "bugged out"?

[mellow elbow]

The loop ended and the coroutine just ended itself even though the condition wasnt met

[swift crag]

while terminates once the expression evaluates to false

[mellow elbow]

Yes

[languid spire]

sounds like the Monobehaviour which started the Coroutine was Destroyed

[mellow elbow]

The debug said it was done (Which happens when the while loop is finished) so i'm not sure

ill just see if it still happens

I seemed to have fixed it

Oh wait

I just recalled

ok I know what's causing the problem

[pallid verge]

how can i find the fuelbar gameobject which has a tag FuelBar?

[rich adder]

FindGameObject with tag returns GameObject

so how do we get a component from gameobject ?

[pallid verge]

i think i know

wait lemme try rq

btw the FuelBar variable is a script right

ik its my code but im not really sure

or a class rather

[rich adder]

its FuelBar type

you need to GetComponent from the returned GameObject

[rich adder]

sure u can make it two lines

[pallid verge]

are u happy now

[rich adder]

looks fine

[pallid verge]

alright ty

[rich adder]

FindObjectOfType can prob be used since it finds the component directly

[mellow elbow]

The scene starts when the variable checked is on 12 for about 45 seconds, and the loop checks every 10 seconds which causes it to stop
I fixed it by adding an extra condition for it to be 12 using ||

the condition is if its less than 6

[pallid verge]

instead of what

[polar acorn]

Just to make sure: is there a reason you cannot just make fuelBar serialized or public and just drag the object in

[pallid verge]

because its for a prefab script and i have to drag n drop it every time

[rich adder]

instead FindGameObjectWithTag
idk which one is faster, but I dont use not to use tags so don't take my word on it 🙂 tag should be fine though

[polar acorn]

Okay just wanted to make sure

A find in start for a prefab is fine

[pallid verge]

i mean its not like im putting hundreds of them but i just wanna have the smallest amount of things to worry about

[pallid verge]

how dont u use tags

[rich adder]

I use components directly

its like a tag but better since you're not bound to strings 🙂

[polar acorn]

If there's only one FuelBar object in the scene though you should use FindObjectOfType instead of getting the object and getcomponent, it's slightly faster

[pallid verge]

yeah there is

[polar acorn]

All Finds can be avoided with proper planning and dependency passing. The object spawning the prefab could set the variable on the instance after spawning one, for example.

[pallid verge]

it works now thank you

[rich adder]

sweet

[pallid verge]

i have another question, can i use a foreach loop in unity?

[rich adder]

ofc lol

[pallid verge]

i was asking cuz i tried to use a while loop and unity crashed

[rich adder]

the only thing unity can't do is run .NET7+ functions

[rich adder]

that will happen if you have infinite loop

regardless

[pallid verge]

oh alright

[rich adder]

while (3<8)
        {
            //infinite loop crash
        }

vs

i = 0;
while (i<8)
        {
            i++;
            //fixed
        }```

[pallid verge]

i know what infinite loops are lol

[rich adder]

just checking

[mellow elbow]

If a Coroutine is Started can it be started again mid coroutine?

[rich adder]

hmm if you store it a variable you can stop and start again

each time you StartCoroutine you create a new one

[mellow elbow]

Im asking so incase the player triggers a coroutine that they cant just spam it

[rich adder]

you can also put a bool

[mellow elbow]

so I false it at the start and true it at the end?

[rich adder]

yeah or opposite, as long as you use that to check before startcoroutine

[mellow elbow]

ah

Makes sense

[rich adder]

 void method()
    {
        if (running) return;
        StartCoroutine(SomeRoutine());
    }
    IEnumerator SomeRoutine()
    {
        running = true;
        while (stuff)
        {
            yield return null;
        }
        running = false;
    }```

[fossil drum]

I honestly don't understand why you don't use WaitUntil, it can't give you an endless loop, it's easier to read, it's less amount of code.

[dim halo]

how can I create a parent object for both text and button at the same time

I would appreciate any kind of help

I'm beginner

[rich adder]

whats the usecase

what are you trying to do with that

[dim halo]

here is the thing, in the tutorial that I'm watching the guy has a parent object called ``game over screen` for both the text and button. Unfortunately, for some reasons that I dont remember, I dont have that one, now im trying to add it

[cosmic quail]

"Create Empty"

[dim halo]

but I want it to be parent object

[rich adder]

just make a gameobject in hirerchy

[rich adder]

so dragthem onto it when u make new empty

[dim halo]

so i should first make a child object under the canvas

[rich adder]

you can also right click one of them and Create empty parent

[mellow elbow]

What does the return do

[dim halo]

and make the text and the button the childs of the child of the canvas?

[cosmic dagger]

Just store the coroutine in a variable, then check if the variable is null. If so, the coroutine is not running . . .

[rich adder]

returns out of a function

[cosmic quail]

yeah right click on the canvas and do Create Empty and then drag your stuff inside that new empty gameobject

[rich adder]

they already are child of canvas

[mellow elbow]

what does that mean

[dim halo]

oh thx

Idid it

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/jump-statements#the-return-statement

[mellow elbow]

Thanks

ah I get it now

why not just use a regular if statement instead of returning if its not true

[rich adder]

You can .
idk wdym a regular if statemnt tho

how i wrote it prevents nesting

[swift crag]

"early return" can simplify functions

public void ReticulateSplines() {
  if (!ready)
    return;
  
  if (!splines.AskToReticulate())
    return;

  splines.DoReticulation();
}

you just quit the function early

[mellow elbow]

I mean instead of this it's
if(running)
{
Startcoroutine(c());
}

[rich adder]

you would need if(!running) Startcoroutine

[swift crag]

in this case it's not a huge difference

and I would probably use an if statement at that point

[mellow elbow]

Forgot

[cosmic dagger]

You don't need a bool at though, just check the coroutine variable instead . . .

[mellow elbow]

How

[rich adder]

StartCoroutine returns a Coroutine object

[mellow elbow]

So it blocks the Statement from happening by returning out of the function?

[cosmic dagger]

Store the coroutine when you call StartCoroutine. Then check if the variable is null . . .

[rich adder]

it "returns" early so it doesnt execute the rest, it doesnt block anything, code runs top to bottom

[swift crag]

I wouldn't say it blocks anything, yes. It just stops early.

[mellow elbow]

I didnt mean it literally

but yeah

[cosmic dagger]

// setup
var coroutine = StartCoroutine(SomeMethod);

// checking
if (coroutine != null) { return; }

[mellow elbow]

How does it return as null

[cosmic dagger]

When the coroutine is not assigned. Inside of your coroutine method, at the end, assign the variable to null . . .

[mellow elbow]

Thanks

[dim halo]

can someone tell me what is wrong with this code?

[rich adder]

its nested inside Update

thefore cannot use accessors

[cosmic dagger]

That means the coroutine variable should be a field (class-level variable) . . .

[dim halo]

how can I do that?

[mellow elbow]

The curly bracket is in between update too

[mellow elbow]

Move it out of update

[rich adder]

pay attention to the brackets

[dim halo]

yeah my bad

thx guys

[languid spire]

if you formatted your code properly you would see the problem

[cosmic dagger]

Your method is inside of another method; this is called a local function (method). When doing this, you cannot use an accessor for the local function . . .

[median vapor]

I have a problem where in my script function "PromjenaDepositZnakova" return true and the if statement doesnt run, it is true for 3 frames, so i thoth that was the problem then i used second variable that makes the "If" staement active until it is finish with the desiered actions but it didn't help, any ideas becouse i have no clue?

[mellow elbow]

nvm That's for a method woops

[dim halo]

I understand, thank you guys

No, configure your editor first, it's pointless to help before that.

[swift crag]

they said it shows you errors

also please learn about arrays, whenever you start using numbering on variables you definitely need a collection

[swift crag]

they didn't ask to show the current errors

[burnt vapor]

My bad

[mellow elbow]

oh

[languid spire]

Also, Random.Range(0,1) aint gonna do a great deal

[rich adder]

also that Random.Range only return 0

(intiger version is max exclusive if you want 1, you always need +1)
Random.Range(0,2) // this gives 0 or 1

[median vapor]

That was me just testing something and messing around with values, later that random will be from 0 to 6 but the real issue is the If argument doesnt react to getting true from the function, ive configureded IDE.

[swift crag]

Do not use deltaTime with mouse input

you're getting a distance, not a velocity

so multiplying by deltaTime is incorrect

You'll need to adjust your sensitivity down a fair bit

It's a common mistake to make

You'll want to think about whether you have a distance (mouse input) or a velocity (joystick or keyboard input). If you have a velocity, use deltaTime to turn that into a distance.

and similarly...

float gravity = -9.81f; // acceleration
velocity += gravity * Time.deltaTime * Vector3.down; // velocity
transform.position += velocity * Time.deltaTime; // position

[dim halo]

can someone tell me why I cant move the number of 1

it is not moving

[cosmic quail]

show the entire screen so we can see what ur actually trying to move

[rich adder]

not really a code question here

[rich adder]

also are you using colliders for UI ? 🤔

[dim halo]

no?

I use colliders for objects

for pipes

[rich adder]

ohh i saw green box thought it was collider

[dim halo]

it's not

I cant move this number

it's so annoying

[rich adder]

did u select the move tool

wdym

[dim halo]

yes

Id did

[rich adder]

idk that size looks extremly large for that box for text

you should learn proper anchoring

this goes in #📲┃ui-ux though

[swift crag]

Yes -- check the docs in there

You should take a little time to read how RectTransforms work. It'll make your life a lot easier

I just kind of stumbled around blindly for a while before I actually read how stuff works

that was as error

Although, other than mouse input, I can't think of any common cases that get messed up

so that's most of what you need!

[polar acorn]

You're in play mode. Do you have code setting its position

You can't move something while code is setting its position -- it'll just move back to where it was

[meager sentinel]

Could someone help me with the ide of VSC?

that dont works

i alr did everything

[cosmic dagger]

VSC is difficult to get setup properly. If following the tutorial doesn't help, you're in uncharted territory. Try to redo it, make sure everything is closed beforehand, restart the computer, open Unity, double-click a script file to open up in VSC and hope it works . . .

[languid spire]

or, better yet, just use VS

[rich adder]

it does work also did you get the .NET sdk

[meager sentinel]

yeah

[rich adder]

try Regen Project files

[meager sentinel]

i get an error that says something about a microsoft error

[rich adder]

show error

[meager sentinel]

WAIT WTH

It works now

the error dissapeared

and i had the error for like 2 days straight

[cosmic dagger]

That reminds me, I need to install and start using Rider. It's wasting away . . .

[rich adder]

u got it free?

[meager sentinel]

i had this error

[rich adder]

weird

[cosmic dagger]

Heavily discounted for under $50 sometime last year . . .

[rich adder]

ohh that aint too bad.. could be great alternative once VS is removed for mac in august . I hate vscode

[stuck palm]

how do i access surface inputs in code?

[rich adder]

whats that ? shader?

[stuck palm]

yeah

[cosmic dagger]

I mainly use vscode bcuz visual studio was bloaty and loaded slow, and luckily, didn't have issues with it breaking

Now it breaks connection often, Unity stopped supporting it, and Rider with co-pilot is ridiculous. The switch is warranted . . .

[rich adder]

Get function in the material should work iirc

[rich adder]

Yeah the new plugin is much better for VScode then the process for before but the intellisense kinda sucks and i still hate the same line formatting (it only formats proper new line for me after i hit save)

im on mac soo and m$ is stopping vs mac support in august so i either go full on VScode or use rider

[swift crag]

The Material class has lots of methods for getting and setting properties

e.g. GetFloat/SetFloat

Note that you need to use the actual name of the property. The name you see in the inspector is generally different.

[stuck palm]

is there a getcolor

and set color

[polar acorn]

Who knows? Maybe the Documentation does

[swift crag]

One way to find out is to right-click on the shader dropdown and click "Select Shader"

so _BaseColor is the correct name to use if I want to adjust the property named BaseColor in the inspector

[cosmic dagger]

Oh snap, that sucks. They're forcing your hand . . .

[chrome wasp]

Unfortunately im back with another issue

using System.Collections.Generic;
using UnityEngine;

public class X : MonoBehaviour

    public bool Turtle;
    public GameObject Bar;
    
     

    void Update(){
        if (Input.GetMouseButtonDown(0))

            Turtle = !Turtle;
        Bar.SetActive(Turtle);
        }


    }
     



    
}

getting some errors with that

Assets\X.cs(18,72): error CS1003: Syntax error, ',' expected

[cosmic quail]

seems like the error says a comma is missing on lines 18 and 72

[chrome wasp]

inside the code there are two things underlined in red. Vector2.0 and hit all on the same line

[chrome wasp]

line 72?

it only goes up to 39

[cosmic dagger]

Column 72 . . .

[cosmic quail]

what is a Vector2.0? theres no such thing

u mean Vector2.zero probably

[chrome wasp]

I'm not sure, I'm fixing my friend's code since he isnt on rn and I need to fix this

[cosmic dagger]

Not sure if Vector2.0 is a thing. Did you check?

[chrome wasp]

yes!!

okay so then there is hit

A local or parameter named 'hit' cannot be declared in this scope because that name is used in an enclosing local scope to define a local or parameter

[cosmic dagger]

Also, you should show a picture of the error, and point out which line is 18 because there are no line numbers when you don't post a link . . .

[solemn summit]

You'er raycasting twice and calling them both hit

Rename one of em

[cosmic quail]

ur declaring something called "hit" twice

[chrome wasp]

So I could change the word hit to like frog or smth

[polar acorn]

Configure your !ide so you see it underlined in red

[chrome wasp]

it is

[cosmic quail]

if they were in separate methods it would be fine. but in the same method, yeah u gotta change one of them

[polar acorn]

Okay, so do you see the red underline on the line with the error

[chrome wasp]

yes

[solemn summit]

Haha, name it whatever makes most sense for what it's being used for, but yes

[polar acorn]

So then that combined with the error should be pretty obvious what the fix is

[chrome wasp]

this dig

[chrome wasp]

well it wasnt

[polar acorn]

Then you should probably learn some basic C# syntax because this line is obviously incorrect

There's no such thing as Vector2.0

[chrome wasp]

I know

We already dealt with that

[autumn arrow]

is there any way to stop animation in milde of palying it ?

using script ?

[chrome wasp]

and it works but now says "There are 2 event systems in the scene. Please ensure there is always exactly one event system in the scene" but it works so

[chrome wasp]

great, and where can I learn that?

[polar acorn]

That'd be because there are 2 event systems in the scene. Please ensure there is always exactly one event system in the scene

[polar acorn]

[solemn summit]

Do you want to pause it, or stop the animation completely?

[meager sentinel]

Ik this may be a very stupid question, since am new on doing particles, but how may i make that a particle appear exactly on where i want? (I have a GameObject that is supposed to be the place where it has to spawn)

[chrome wasp]

Who could have thought. Why do I have to change it though if it works

[cosmic quail]

by default it should appear where the gameobject is at

[polar acorn]

Because it's going to stop working as soon as you try to actually do anything with the event system

[meager sentinel]

So i have to place it as a child?

[autumn arrow]

im working o blocking system in sword combat and as soon as i hit a colider with tag enemy whle blocking i want to stop the animation and play the one that i got blocked

[cosmic quail]

yeah that works

[chrome wasp]

Okay, thank you

I will fix it

later

[polar acorn]

It literally takes one keystroke

Just delete the extra one

[solemn summit]

Just have to have a transition to the "Bounce Back" animation or whatever, and set a trigger for it.

And make sure the transition does not have an Exit Time.

[cosmic quail]

also after setting it to be the child, change its coordinates to 0 0 0 if u want it to go into the center of the parent

[meager sentinel]

Yeah but the object deactivates itself on trigger, are there any other options?

[cosmic quail]

is it a moving object?

[meager sentinel]

Yeah, it's an enemy

[chrome wasp]

but im stupid and dont know which system is extra. i have two weeks to make a game and i dont know c# so im just trying to cobble it together. Im learning c# at the same time

[cosmic quail]

theres something about the particle system that lets you set a source or something, i dont remember exactly

[polar acorn]

It literally does not matter which one, just delete one

[cosmic quail]

https://docs.unity3d.com/ScriptReference/ParticleSystem.Emit.html this takes a position as a parameter from where u want to emit it from

[meager sentinel]

ty

[chrome wasp]

oh i see one is clickposition and one is mouseposition

[polar acorn]

...what?

Did you rename them?

[chrome wasp]

No but there are two things and each are the same code but one is click position and one is mouse position

[polar acorn]

What does that have to do with the extra Event System

[solemn summit]

Are there two separate game objects named that? And both have identical Event Systems on them?

[chrome wasp]

is that not the second event sytem

[chrome wasp]

no game objects are named clickposition or mouseposition

[solemn summit]

Have you located the two event systems?

[stuck palm]

why isnt this working?

[cosmic quail]

event systems are in your hierarchy, not code. its a gameobject called EventSystem

[polar acorn]

Event System is an object

called Event System

[slender nymph]

Why would it work?

[polar acorn]

In what way is it not working

[autumn arrow]

im prety new to the animator im trying to replicate this type of combat (he is using animator to do all this) u have any idea how to do this ?

[solemn summit]

Layer is an Int

[cosmic quail]

alternatively it could be called something else if it was renamed. in that case click on the gameobject and in the inspector you will see a component called Event System. you should only have one of these in your scene

[stuck palm]

how can i get the name of a layer? layer.name doesnt work

[solemn summit]

https://docs.unity3d.com/ScriptReference/LayerMask.NameToLayer.html

[chrome wasp]

weird well I ddeleted the game object called Event System

I do not even recall making that\

ever

[cosmic quail]

it gets made automatically when you have something in your scene that requires it. no idea how you got it twice though

[chrome wasp]

what but now I have nothing called that in that section

[rocky canyon]

any suggestions on how to do the aiming mechanic for this?

quick breakdown its a point and click to move type bullet hell game where positioning is a core mechanic (autobattler) you'll end up moving by clicking the unit and drawing a path.. every X amount of mouse movement will trigger a new node/waypoint..

i dont want it aiming at the mouse all the time.. i'd want it to aim the direction its walking.. unless i give input to tell it to aim somewhere else.. (a general direction)
i was thinking like click and drag and release.. to give it a direction..
and since hes moving.. id have like a big buffer zone where u wouldnt need to click exactly on him, just nearby
but.. then once he gets to the next point he'll look the direction hes walking again.. or maybe he wont.. im unsure at this point.. just trying to think out the next system i gotta make

[solemn summit]

In the Animator window, you can right click on an animation and Make Transition and link it to another anim. In the Parameters, make a new Trigger, call it whatever you want. Click on the line, turn off Has Exit Time in the settings and add the Condition of your new trigger. In code, call animator.SetTrigger("TriggerName") to transition to the new anim.

[autumn arrow]

folow the mouse mby ?

[cosmic quail]

u must have some event system component on one of ur gameobjects which u accidentally added onto it? cuz it said u have 2

[chrome wasp]

huh

now its telling me a tag isnt definied

i am going to lose it

[polar acorn]

That would probably be because a tag is not defined

[chrome wasp]

public GameObject ExitButton; does that not count

as defining it

[polar acorn]

That makes a variable named ExitButton that can hold a GameObject and has absolutely nothing to do with tags

[chrome wasp]

how do i define it then

[polar acorn]

First off, what is the exact error you're getting

[chrome wasp]

because it was working before when it was named X and there was no tag define

[cosmic quail]

https://docs.unity3d.com/Manual/Tags.html

[chrome wasp]

Tag: X is not defined.
UnityEngine.StackTraceUtility:ExtractStackTrace ()
X:Update () (at Assets/X.cs:26)

[polar acorn]

Okay, so you have no Tag in the project named X

Add one

[chrome wasp]

so do I just throw GameObject.FindWithTag("ExitButton") at the top

[cosmic quail]

no check my link to see how you can add a tag into your game

[chrome wasp]

okay

[cosmic quail]

ur code is looking for a tag named X so u gotta make a tag named X

[polar acorn]

How are you going to find a tag you do not have

[safe barn]

If you cant figure it out, just use GameObject.Find("yourgameobjectname");

[polar acorn]

Or: Best solution, don't use Find at all and just drag in the reference

[cosmic quail]

hes using CompareTag

[chrome wasp]

    ExitButton = GameObject.FindWithTag("ExitButton");
    Instantiate(ExitButtonPrefab, ExitButton.transform.position, ExitButton.transform.rotation) as GameObject;```

I followed the website

it still does not work

[cosmic quail]

did u add an X tag and a ExitButton tag?

[chrome wasp]

I dont need an X tag because Im just trying to deal with ExitButton

[safe barn]

So you do need an ExitButton tag

You do

[polar acorn]

Do you have a tag ExitButton

Show it

[cosmic quail]

u still got that CompareTag(X) tho

[chrome wasp]

but it never mentions X as a tag

[polar acorn]

Also your if statement contains nothing

[chrome wasp]

using System.Collections.Generic;
using UnityEngine;

public class X : MonoBehaviour

{
    public bool Turtle;
    public GameObject ExitButton;
    public GameObject Bar;

    void start()
{     
    if (ExitButton == null);
    ExitButton = GameObject.FindWithTag("ExitButton");
    Instantiate(ExitButtonPrefab, ExitButton.transform.position, ExitButton.transform.rotation) as GameObject;
}
    
     

    void Update(){
        if (Input.GetMouseButtonDown(0))
        {
            //cast ray from mouse position
            Vector2 clickPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            RaycastHit2D frog = Physics2D.Raycast(clickPosition, Vector2.zero);

        }

Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        RaycastHit2D hit = Physics2D.Raycast(mousePosition, Vector2.zero);

         if (hit.collider != null && hit.collider.gameObject.CompareTag("ExitButton"));
        {
            Turtle = !Turtle;
        Bar.SetActive(Turtle);
        }


    }
     



    
}

[cosmic quail]

ok u renamed the X to ExitButton

[chrome wasp]

yes

[polar acorn]

So show your ExitButton tag

[cosmic quail]

all u need is to make an ExitButton tag then

[safe barn]

Add a tag to the GameObject

name it ExitButton

yes

Where do you call Uptade

[cosmic quail]

https://docs.unity3d.com/uploads/Main/tag-dropdown.png

[safe barn]

Change it from Uptade to Update

[queen adder]

oh mb

tysm

[chrome wasp]

wait

okay so

am I supposed to use ExitButton in that or respawn

[polar acorn]

If you want to find an object with a tag, you need to have an object with that tag

[chrome wasp]

great okay I made a new tag called ExitButton

[cosmic quail]

the new code u added is completely unneccessary and used for something else. it was just an example in the docs. all u need to do is click Add Tag like that image i showed and its done

[chrome wasp]

ok well now everything is broken

this has somehow broken another set of code

im just going to stop for a bit

[polar acorn]

Honestly this entire script is basically nonsense. You just never realized it because it errored out immediately and never ran any of it

[chrome wasp]

well we can blame my friend for that. I will let him now the script doesnt work

[cosmic quail]

maybe ur friend generated this code with chatgpt

[chrome wasp]

idk how he got it

the point is the raycast method he was trying to use worked for the dragging code he make

[swift crag]

The raycasting code makes zero sense.

maybe it can indeed work like Physics2D.OverlapPoint when the direction vector is Vector2.zero?

[polar acorn]

Let's see:

1. start will never be called by Unity for similar reasons that other question we answered won't run Uptade
2. If statement with nothing in it
3. Instantiating a prefab that literally does not exist in the code
4. The entirety of the first if statement in Update does nothing whatsoever. It spins up a few local variables, does nothing with them, then ends.
5. Raycast with a direction of 0
6. Superfluous boolean (with a very strange name) for toggling Bar, can just set the object's active state to whatever it isn't

D- see me after class

[gusty hazel]

hi im adding sounds to my game and ive got a audiomanager script https://hatebin.com/mpulbheocp attached to a game object tagged audio manager which doesnt destroy

i then find the object with my player and send a message to use the Play function https://hatebin.com/clevgevhdp

but wether i put this AudioManager = GameObject.FindGameObjectWithTag ("audio"); in start or update it doesnt work

[solemn summit]

is it tagged 'audio manager' or 'audio'?

[gusty hazel]

just audio

[slender nymph]

Show the object and its tag

[rich adder]

that else if statement is haunting

[gusty hazel]

thanks

[solemn summit]

AudioManager in your PlayerController is a GameObject. You'll have to get the AudioManagement component, will you not?

[slender nymph]

This whole setup is haunting tbh

[gusty hazel]

ive tried that too

[rich adder]

Putting this in Update omg

[gusty hazel]

but that also doesnt woek

[slender nymph]

Who needs to reference the component and call methods on it when you can just use a dirty method like SendMessage and not even care about whether you're referring to the correct type of object

[gusty hazel]

i tried it in start and it didnt work testing :/

[polar acorn]

Jesus christ how horrifying

[rich adder]

it doesnt work because ur not calling it from the instancea nvm ur just not Getting the Component from GameoObject

[gusty hazel]

ive tried that tooo but we got taught to use send message]

the rest of my code uses references promise

[polar acorn]

Slap whoever said that

No cop would convict you

[gusty hazel]

teacher :p

[rich adder]

bad teacher

[gusty hazel]

fr

[solemn summit]

I don't think I have ever typed the words SendMessage before in my life

[rich adder]

a sane person would at least learn events since thats what its trying to mimick

[polar acorn]

SendMessage is an ancient solution to a problem that existed fifteen years ago and should have been removed when they removed .collider and the like

[swift crag]

I would only use SendMessage if I genuinely needed to trigger a method on a completely arbitrary component

[gusty hazel]

im using Unity 2018.2 and Monodevelop

[swift crag]

with no ability to specify the signature of the method ahead of time

[solemn summit]

Anyway, we've dogged on the setup, what are people's recommendations for a rework here?

[gusty hazel]

cant even use a newer unity bc its coursework

and got to do it on school computers

[swift crag]

i'm developing some Opinions over here

[rich adder]

just calling the method on the reference should be sufficent

[polar acorn]

1. Change the AudioManager reference to an actual component reference
2. Drag in from the inspector if possible, if not at least use the Find once, in start
3. Call the Play function directly instead of through send message

[swift crag]

If you need to call Bar, a method that's part of a class named Foo, you should get a reference to the object and call the method directly.

[SerializeField] Foo myFoo;

void DoSomething() {
  myFoo.Bar();
}

[wanton cargo]

Hi I'm not sure wher eto ask about this issue, but I just created a new URP project and after I select the camera it stops rendering anything... does anyone know how to fix this? https://i.gyazo.com/eeb3bb31290ccb04a014ff367bc35c54.gif

[rich adder]

where da code question ?

[wanton cargo]

Like I said I'm not sure where to ask this

[rich adder]

#💻┃unity-talk for anything else
also would show the inspector more

[wanton cargo]

Ok thanks I'll ask there

[swift crag]

this ensures that you actually have a reference to a Foo, not just some random object

and it's a lot more efficient to call a method instead of using SendMessage

Unity has to go rooting around in the guts of the target to see if a method with the appropriate name exists

[solemn summit]

Or be incredibly lazy like me and learn Singletons and abuse them so badly but never let anyone look at my code

[rich adder]

Singletons get unnecessary bad rep

[gusty hazel]

will finding the component through start work if it is on Dontdestroyonload

or should i just put it on each scene

[rich adder]

not if they're not both in DDOL

[cosmic quail]

every good game has dozens of singletons

[rich adder]

you can use a singleton though

[swift crag]

I forget how the Find methods work with multiple scenes

[rich adder]

iirc they do not last I tested

[swift crag]

If the "Audio Management" component is getting punted to another scene, then I think it's very reasonable to just make it a singleton

[eternal needle]

"B-b-but my DI!!"

[swift crag]

hot take: singletons are dependency injection

[rich adder]

why not both

[swift crag]

your object gets its value from somewhere else

[eternal needle]

Or the other one people say, mock testing

[rich adder]

anytime I make a ASP.NET app I have DI + there is a AddSingleton for it

[swift crag]

time to mock out the final boss from my game so i can test...something

[rich adder]

https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.servicecollectionserviceextensions.addsingleton?view=dotnet-plat-ext-8.0
basically a singleton ^

[swift crag]

to explain what we mean by this "singleton" business

a singleton is something that exists exactly once

If you have many copies of something, you can't just say "give me X" and get the exact instance you wanted

if there are 10 enemies, you can't just...pick one at random to deal damage to

But when there's exactly one instance of something, you can always get exactly the instance you wanted

The easiest way to make a singleton is to do something like this

public class AudioSystem : MonoBehaviour {
  public static AudioSystem instance;

  void Awake() {
    instance = this;
  }
}

you can now reference the audio system from anywhere as AudioSystem.instance

(not in other Awake methods, since they might run before the AudioSystem's Awake does)

This is not the best way to do it for a few reasons (the timing issue, nothing stops you from making multiple instances by mistake..)

But I think it's very serviceable here.

Before you make something a singleton, you must ask yourself if it's truly only ever going to exist once.

Oftentimes, singletons will be "manager" types

look at my cute little managers

[rich adder]

I access my other managers by 1 main manager so I just make that the singleton and grab the rest with props,
imo no need to make 20 diff managers singletons

[swift crag]

the Game one is mislabeled

don't tell anyone 🤫

[swift crag]

That's also a good idea

[solemn summit]

private void Awake()
    {
        if (Instance == null)
        {
            Instance = this;
        }
        else
        {
            Destroy(gameObject);
        }
    }

Just to keep things clean

[swift crag]

I have one true god-manager -- the GameController -- that lives forever and keeps track of high level game state

and then I have others that only survive for a single scene

[swift crag]

(hence why "Game" is a bad label...it's not called that anymore. i should change that)

it's the Encounter Manager now. it handles a single encounter in the game

[rich adder]

MainBoss

xD

[swift crag]

i'm having animation nightmares today and I still have a cold, so I'm taking it easy lol

[cosmic quail]

do u call Manager.Instance a lot of times from other scripts without caching it or do you cache it into a variable in each of your scripts?

[swift crag]

I prefer not to cache when it's such a tiny thing, personally

[rich adder]

no need the instance is pretty much a prop so

[swift crag]

Unless it's a mega-hot code path

that'd still be really marginal

[rich adder]

yea

[swift crag]

If I have a loop that runs 20,000 times per frame, I store the value I got from a dict instead of reading it thrice

Although, it can be hard to tell how important those tiny function calls actually are.

Deep Profile adds a huge amount of overhead to each function call, so lots of tiny calls get blown out of proportion

(I did still see a minor gain in regular profiling in that case)

[buoyant knot]

Debug.Assert becomes super expensive in deep profiling

especially if you have a formatted/concatenated string message

[eternal needle]

Debugging or writing is always expensive, concating strings is also a bit of allocations

[queen adder]

using UnityEngine;

public class Bullet : MonoBehaviour
{
    public GameObject impactEffect;
    public float life = 3;

    void Awake()
    {
        Destroy(gameObject, life);   
    }

    void OnCollisionEnter(Collision collision)
    {
        if(collision.gameObject.tag == "enemy")
        {
            Destroy(collision.gameObject);
            GameObject ImpactGO = Instantiate(impactEffect, hit.point, Quaternion.LookRotation(hit.normal));
            Destroy(ImpactGO, 2f);
        }
        Destroy(gameObject);
    }
}

Hello, i am new at unity and i need help with sharing variable between 2 scripts my first script has a correct value of 2 and my second script has a value of 0 that's probably because the value cannot be shared to the other script.
Is there any way I can fix it?

how can i change this hit to like collide or something bcs i copied it from raycast thing

Hey, guys! I have a question. How to don't give permission to the player to interact with any button before the game starts, for example I want to make a functionality that the player enters the main scene of the game and when it enters then to give the permission to the player to interact?

[polar acorn]

A boolean and some if statements

I have already the functionality of the player movement. What I want is to make that happen. I will show you my player movement code now give me a minute.

    if (Input.GetKeyDown(KeyCode.Space) && uiManager.pauseIsActive == false)
    {
        playerRb.AddForce(Vector3.up * jumpForce, ForceMode2D.Impulse);
        audioManager.PlayerJumpSound();

    {  
        audioManager.jumpSoundAudioSource.Stop();
    }
}```

I am giving force to the player with a space button here!

[polar acorn]

If you don't want the player to move before the game starts, but the object exists anyway, use an if statement to only run your code when you're supposed to

[short hazel]

Collisions have contact points. You can access the first one using collision.GetContact(0), then access its .point and .normal properties

[sage mirage]

I didn't clarify that correctly I just want it to happen at the period when the player start moving at players position which is behind the main scene to the starting point position where the game actually starts and the player can interact with the buttons and all.

[polar acorn]

If you want some condition to be true before accepting input, wrap the input in an if statement

whenever the player collects a battery the battery is SetActive(false)

and the tag name is right

Find methods don't find inactive objects

[polar acorn]

If works but it doesn't do anything. The objects are already active so activating them again won't matter.

https://docs.unity3d.com/ScriptReference/GameObject.FindWithTag.html

[pallid verge]

will it activate the ones that arent active?

[short hazel]

No because Find doesn't find inactive objects

[pallid verge]

ohhh

[polar acorn]

Returns one active GameObject tagged tag

what if i make that array at the start of the game?

when all the batteries are active

will it store them even when they are inactive

I'm trying to figure out the best way hypothetically to effectively store lines for a game in an organised and expandable way.
I discovered json, which seems like a pretty solid way to do it, but because this requires an object type to be defined to be serialised to, I don't think this would be the ideal use case for it as I don't want to make a new object for every line.

[rocky canyon]

why not use 1 type.. with as many ever properties as you need?

[polar acorn]

A JSON file can contain an array of strings just fine, and you'd only need one class

[misty hedge]

ah! I did not know that

That solves the problem, thank you

[lament sable]

https://hastebin.com/share/duremowage.csharp and https://hastebin.com/share/oligicisek.csharp I don't know why the 'level' is not the same for both can sommme wan exsplane what is wrong

[polar acorn]

Eeach script has their own variable named level

They have nothing to do with each other

[lament sable]

theye are conected by the [SerializeField] public StarterTexstScript starterTexstScript; and [SerializeField] public Doorscript doorscript;

[polar acorn]

That has nothing to do with level

You have a reference to the other script but you aren't using it anywhere

You are just using this script's level variable

[lament sable]

how do I fix it than Idk what I can do about that ?

[polar acorn]

If you want to use the level variable from the different script, get it from your reference to that script

[lament sable]

yes but how ?

[polar acorn]

With .

[lament sable]

what I don't get it

[rocky canyon]

theOtherScript.level =

if you just say level = your basically saying this.level = which is the level within that class

[polar acorn]

someReference.variableYouWantToUse

[lament sable]

like dis ? : Doorscript.level

[polar acorn]

[rocky canyon]

u don't use the Type

[lament sable]

but there is a red line under it

[rocky canyon]

you use the name you gave it

[polar acorn]

And what does it say

[lament sable]

[SerializeField] public Doorscript.level;

[rocky canyon]

negative

[polar acorn]

No

[lament sable]

br pls I don't know

[polar acorn]

Use the level variable from your Doorscript in code

Do not have a variable level on this script

[rocky canyon]

public DoorScript doorscript;

doorscript.level

you have 2 different levels in ur scripts.. one belongs to one script the other belongs to the other script..

if ur in one script and you want to access the level in the other script.. you have to use the variable OF that script..

but WITH the name

[lament sable]

that is in my script

[polar acorn]

So use that

[lament sable]

so if (doorscript.level == 2){}

[swift crag]

[SerializeField] <-- asks Unity to store this field, even if it isn't public
public <-- allow anyone to see the field
Doorscript <-- this field holds a "Doorscript" object
doorscript <-- the name of the field

the name of the field is the only part you need to write to access the field.

[rocky canyon]

this will use the "level" variable of the script that you declared as "doorscript"

makes sense to me

[lament sable]

but it doesn't work

[swift crag]

if it worked, you wouldn't be here asking about it!

in what way does it not work?

[lament sable]

the eror is :
'Doorscript.level' is inaccessible due to its protection level

[polar acorn]

private means the variable can only be used inside the class it's defined in

[rocky canyon]

protection level.. thats the public, private, static part u put before the type u declared

[lament sable]

the level isn't the same in the to scripts

[swift crag]

well, it sounds more like the code doesn't even compile

[lament sable]

yhea I know

[rocky canyon]

public means u can access it anywhere.. private means you can only access it in the script that it sits in, and static isnt important right now..

well..

[polar acorn]

If you know then why did you post your error here instead of just fixing it

[rocky canyon]

u can't access a private variable from an external script..

you need to use a public variable.. if u want to access it from other places..

i dont think he's using his brain.. other than fishing for exact solutions

[lament sable]

I don't know what is ronge but I am gane restart my pc so bey I tink i fix it btw

        if(gameIsPaused)
        {
            Time.timeScale = 0f;

        }
        else

            Time.timeScale = 1;
            pauseNotif.SetActive(false);
        }
    }``` i thought when you set timeScale to 0 the update stops

guess thats not teh case

[slender nymph]

no, update is still called. but deltaTime will be 0

[rocky canyon]

ahh so its fixedupdate

ya, i just had em mixed up

thats great news tho, i was thinking id have to do something complicated to achieve a pause

[swift crag]

This can also happen when you start the Recorder

that caused some funny problems for me (division by zero)

[rocky canyon]

hehe.. still a few things to work out

[misty hedge]

I may be stupid but I'm at a loss. Trying to read this simple array from a file is so far doing nothing...

[swift crag]

That class does not match your data

Your data contains a single object. The object has one name -- "Scene" -- and one value -- an array of strings

Your Scene class has a single array of strings named "Lines"

These do not match at all.

[polar acorn]

1. Don't name this Scene, that's a Unity class, you should use unique names
2. Create one manually using ToJson so you can see the format, then you can edit it outside of Unity to change it

[swift crag]

Each field on your class will become a name in an object. So you'd better have "Lines" somewhere in your JSON!

^ and yep, just produce an example to look at

[misty hedge]

Aeugh. I haven't used JSON since modding minecraft years ago and it shows

I will produce an example then!

[olive lintel]

Hey guys, I was trying to see if theres a simple way to find the total length of a slerp curve, as in, vector3.distance between 2 points, however while accounting for a third midpoint somewhere. I did find the following solution:

 Vector3 previousSample = A;
 float distance = 0;
 for (int i=1; i<sampleCount; i++) {
     Vector3 sample = Vector3.Slerp(A, B, (float)i/(float)sampleCount );
     distance += Vector3.Distance(sample, previousSample);
     previousSample = sample;
 }```
but it seems rather crude and I was wondering if theres a simpler/mathematically perfect solution out there?

[wintry quarry]

Well assuming your vectors are both the same length it's a simple matter of taking the angle difference as a portion of the circle circumference

[olive lintel]

you mean as in the distance from the midpoint? see they might not always be the same is the problem :/

[wintry quarry]

No. I mean distance around the circumference of the circle

It's odd to be doing slerp between non-unit vectors

[swift crag]

It's non-trivial for two differently sized spheres

It's pretty reasonable!

I've used it for moving a look target from place to place

[wintry quarry]

I would think you just take the average of the two circumferences if they're not the same length

[swift crag]

(well, I really did a cylindrical lerp, but that's just XZ slerp + Y lerp)

I think I looked into this before. I didn't get a good answer.

You can approximate it by just sampling a bunch of points, of course. Looks like that's what you did.

[pallid verge]

what would this error mean? this is the script

it doesnt give me any errors in my ide

[swift crag]

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

[ancient island]

hey guys, I have an animation that rotates an object clockwise by 360 degrees forever (in case you ask, yes, I need an animation because then I can take advantage of animation speed). In a given moment I need to stop the animation at whichever rotation the object is and make it return to its original rotation (0, 0, 0) in exactly 2.25 seconds. any idea about how to achieve this?

[swift crag]

Read through the "Troubleshooting" links on that page.

[slender nymph]

probably calling this method before the singleton instance has been created

[olive lintel]

I think I know what you mean, basically just take the angle difference from the midpoint to the start/end point, then just do 2pir*angle/360, with r being the average distance between the start/end point and the midpoint, and with "angle" just being the angle I found earlier?

[swift crag]

The average radius is probably an okay approximation

[slender nymph]

why exactly do you need an animation for this instead of just using something like Transform.Rotate and a scale value?

[ancient island]

because of animator.speed

[swift crag]

If you want to be able to vary the speed, just...change the amount you rotate by

[slender nymph]

again, scale value for controlling the speed

[polar acorn]

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

[solemn summit]

You could control the speed of the rotation in code

[slender nymph]

in fact, you would have more control over the speed if you do it via code

[pallid verge]

so that something is _optionsData.masterVolume right?

[slender nymph]

it could be that, or it could be your singleton instance

[pallid verge]

idk what that means

[polar acorn]

It could either be AudioManager.Instance or _optionsData

[pallid verge]

if it was audiomanager instance wouldnt the next lines of code give an error too?

[swift crag]

why would they? you never reach them in the first place

[slender nymph]

it wouldn't reach the next line of code

[polar acorn]

How would it reach those lines, it's already died

[pallid verge]

oh

[swift crag]

Runtime errors aren't going to show up in your code editor.

You'll see errors in your IDE when there's something provably wrong with your code

int x = 3.5f;

this is a compile error because you can't assign a float into an int variable

var foo = GameObject.Find("What");
foo.name = "Hi!";

This will throw an exception unless there happens to be a game object named "What" in your scene. The compiler can't prove that, though. Everything is structured perfectly correctly.

[misty hedge]

Figured out how to serialize and de-serialize JSON properly for strings and integers, but noticed this in the documentation:
Unity does not support passing other types directly to the API, such as primitive types or arrays. If you need to convert those, wrap them in a class or struct of some sort.
I'm not quite sure what it means by 'wrap them in a class.'

[pallid verge]

alright so i think i found my error, that applyalloptions method is called in a Load method and that Load method is called in Awake

could that be it?

because awake is before the first frame so the audiomanager doesnt exist yet

[swift crag]

string[] myStrings; // can't serialize this
MyClass myStuff; // can serialize this

where MyClass is

[System.Serializable]
public class MyClass {
  public string[] strings;
}

The corresponding JSON would be

["a", "b", "c"]

and

{ "strings": ["a", "b", "c"] }

respectively

[misty hedge]

Oh wow, thank you! That's exactly what I needed to know

[timber tide]

well, you can probably get the time between the start and end keyframes and normalize them values. Then from the point from where you stopped, you need to figure out the speed needed to get back to 0.

[slender nymph]

this is a code channel

[keen ice]

I was wondering if you can add a script

To block a animation

[swift crag]

this sounds a lot harder than being able to just do...

[SerializeField] float spinRate;
private float returnRate;
private bool spinning = true;

void Update() {
  if (spinning)
    transform.Rotate(0, Time.deltaTime * spinRate, 0);
  else
    transform.rotation = Quaternion.RotateTowards(transform.rotation, Quaternion.identity, returnRate * Time.deltaTime);
}

public void Return(float duration) {
  spinning = false;
  returnRate = Quaternion.Angle(transform.rotation, Quaternion.identity) / duration;
}

that'd do the trick!

[pallid verge]

could this be it?

[timber tide]

yeah if you just wanna do it without the animator

[keen ice]

oj my bad

[timber tide]

but if the clip is just a rotation then yeah use rotational methods

[fringe kindle]

Trying to add a countdown timer to the start of my game but when I press E (the key to activate it), it just goes on to 3 and stops there.

[misty hedge]

There we go, I can work with this now. Tysm for the help!!

[swift crag]

If you want to do more complex serialization (like serialization of dictionaries), consider Json.NET

[polar acorn]

Is the object this script is on ever disabled or destroyed

[fringe kindle]

It's on the UI object, which is enabled at the start

[polar acorn]

I didn't ask what it was at the start, I said ever

A deactivated or destroyed object ends all coroutines

[fringe kindle]

Some of the objects parented to UI get disabled, as part of the countdown process

but other than that, that's pretty much it

[polar acorn]

Is this object ever destroyed or disabled

[fringe kindle]

No

[polar acorn]

the one the coroutine is running on

[polar acorn]

Have you changed the TimeScale

[fringe kindle]

Timescale at the start is 0

Should've shown that as well as the void update

[polar acorn]

Timescale affects WaitForSeconds

[fringe kindle]

Ah

[tawdry rock]

Anyone can help? I want to create bullet holes on wall and i having these flickering images.
I made a Quad, inside a new gameobject with sprite renderer and i attached my bullet hole. Made a material for it then prefabed it.
Code im using:

 if (hit.collider.CompareTag("wall"))
 {
       Instantiate(bulletHole, hit.point, Quaternion.FromToRotation(Vector3.forward, hit.normal * 0.025f));
     
 }

[fringe kindle]

Is there another way to pause everything without affecting WaitForSeconds?

[polar acorn]

https://www.youtube.com/watch?v=KPaEnLpu57s

[waxen oracle]

Is there any definition for something like child in the transform?

or children

[polar acorn]

Check the documentation:
https://docs.unity3d.com/ScriptReference/Transform.html

There are many methods and functions at your disposal

[golden otter]

you could use WaitForSecondsRealtime, but for a better pause system you should check the video linked here

[rich adder]

are you using URP just use decal projector instead of quads

[swift crag]

one note: there's no point to multiplying hit.normal by anything

FromToRotation just goes between two directions.

Did you want to offset the bullet hole from the wall? You need to add hit.normal to the position you spawn at.

[tawdry rock]

Yes, URP but i can't find where could i enable decals, also i using multiplying so the hole wont appear on the surface of the wall to prevent flickering but it not works.

[fringe kindle]

That worked fine dor me 👍

[rich adder]

its a Renderer feature

[lone finch]

Im trying to make a disjointed hitbox to detect ground collisions, but it dosen't seem to be working. What could i be doing wrong? `{
public GoblinMoves myGoblinMoves;
public GameObject myGoblin;
public float yValue;

private void Update()
{
    yValue = (float)(myGoblin.transform.position.y - 0.03);
    transform.position = new Vector3(myGoblin.transform.position.x, yValue);
}
private void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.collider.gameObject.layer == LayerMask.NameToLayer("Ground"))
    {
        myGoblinMoves.jumpSpeed = myGoblinMoves.jumpSpeedControl;
        myGoblinMoves.jumpCount = 0;
        Debug.Log("Detected Collision");
    }
}

}`

to clarify i get no collisions

[polar acorn]

Log the object you hit outside the if statement

see if you're colliding with anything at all and if that thing is the object you expect it to be

[tawdry rock]

I tried that but i have 3 option that (performant, high fidelity and balanced)

[rich adder]

well you can pick which graphics settings you want to add it to

[tawdry rock]

and where can i see which one the project use?

[rich adder]

Edit > Project Settings > Graphics

[smoky niche]

Hey there, does anyone here have any experience with the System.Diagostics.Stopwatch? Is it more accurate than Coroutines or timers in an Update loop?

[lone finch]

apparently not

[polar acorn]

The Three Commandments of OnCollisionEnter2D:

1. Thou Shalt have a 2D Collider on each object
2. Thou Shalt not tick isTrigger on either of them
3. Thou Shalt have a 2D Rigidbody on at least one of them

[tawdry rock]

thank you, i was adding this to balanced and it use high fidelity. i will try mess around with it now

[golden otter]

It's more suitable for performance measures

[lone finch]

does it matter if i put the component on the tilemap for the hitbox gameObject?

also whats the easiest way to disable physics

[smoky niche]

Oh alright thanks!

So is there any way to accurately check for milliseconds

Since coroutines and normal timers don't seem to be millisecond accurate

[golden otter]

why do you need ms accurate methods?

[vale geode]

hi can i ask for some help?

[shell sorrel]

anything you do in unity will be happening on a frame, so you can can accurately mesaure time but your code will all be executing on frames

[smoky niche]

I'm making a game where you have a couple of invincibility frames if you get hit and use a coroutine for it. The difference in time is always a bit different though, and I would want it to be as accurate as possible since it's a precise platformer game

[golden otter]

sure

[vale geode]

im having some problems with a ray not apearing in the scene i dont know what to do

[polar acorn]

So what's wrong with using frames

You physically cannot interact with anything between frames

ur supposed to like read the massage bruh

[desert elm]

question, is it possible to run the game window at one frame intervals?

[polar acorn]

Yes, that's what the button next to pause does, it advances exactly one frame

[desert elm]

oh okay

[rich adder]

you mean set custom fps? nvm

[polar acorn]

Run the game, pause it, and you can frame-by-frame with the third button

[smoky niche]

True, but how would I use something like WaitForXAmountOfFrames?

[tawdry rock]

well my bullet holes are worse now thru decals

[rich adder]

how so ?

[vale geode]

´´´cs

[polar acorn]

Just use a normal timer, the most it can be off by is one frame.

[slender nymph]

just use a bin site, mate

[rich adder]

weird I dont get Zclip. Try moving it slightly outward from normal

[tawdry rock]

I have to go, will be back in a hour. but thank for the help so far

[vale geode]

im not really understanding how to use the sites

https://paste.myst.rs/yc10en2k

[rich adder]

lord..

[vale geode]

sorry

[polar acorn]

Okay, good. Now what is the actual question

[rich adder]

so is Gizmos enabled ? and are u sure script is running?

[buoyant knot]

It’s more consistent to use a timer in sec, unless you want to offset some process by exactly 1-2 frames.

Coroutines are good to delay something by some amount of time and/or frames.

[vale geode]

yes the script is running and i saw the ray line but somehow it stoped working when i switched to private the (public camera cam)

[polar acorn]

Does this object have a Camera component on it

[rich adder]

so you have errors in console?

[vale geode]

yes

[vale geode]

no

[polar acorn]

Show the inspector of it

[polar acorn]

Okay so you lied

[rich adder]

tisk tisk

[vale geode]

main camera?

[rich adder]

you see what you're doing here?
cam = GetComponent<Camera>();

[polar acorn]

So the code is doing exactly what you asked

You only draw the ray if this object has a Camera component on it

since it doesn't have one, you don't draw the ray

[vale geode]

but the camera is set as child on the object

[polar acorn]

You aren't checking any children

[vale geode]

do i drag it in?

[polar acorn]

you're checking this object

which doesn't have one

[rich adder]

then you have to remove the GetComponent if you do

GetComponent will override the inspector, always

you had it assigned but at runtime it was null

[desert elm]

is there a default circle outline sprite in unity?

[rich adder]

so its working?

[desert elm]

oh great

[vale geode]

the red ray is what i wanted to see and was working before, but when i press play i have to select the camera on inspector, i didnt figure out to to put the camera in the inspector from the hierarchy

[rich adder]

did you not read the previous messages?

[slender nymph]

it's because you were overwriting the already assigned camera with your GetComponent call

[misty hedge]

Because I've been sitting here for a while pondering this, I'm wondering if there's a better way to do it.

I want some dialogue to trigger a delay, so there's a few seconds of nothing before another line pops up. The way I was going to implement this was have some lines in the text file simply say "t=5", and when I read the dialogue, these get omitted and a separate list tracks when the current line index matches this delay index, and waits.

Does Unity have any built-in systems to handle events like this that would be less crude and easier to edit?

[frosty hound]

No, you either make it yourself, or you use very well done assets like Text Animator off the store.

[vale geode]

yes thanks for the help

i did it its working

[queen adder]

Hi, my project is on unity vers 2021.3.18f1, I have the input system version 1.4.4 but I need 1.7 for a certain feature. How can I get 1.7 in my project instead?

[rich adder]

update it?

package manager

[misty hedge]

Alright. I think I'll step back and make a proper event scheudling system for my games instead of continuing this hacky one, then

[queen adder]

it wont give me that option it says "up to date"

[smoky niche]

Sounds good, thanks

[rich adder]

hmm maybe because im on 2022

doc says 2019+

[queen adder]

yeah I checked, its got me confused, I dont know if there is maybe a git url install or something?

[rich adder]

works fine 2021 just checked

maybe remove it and try adding again

[rich adder]

did you add via git or something?
Remove and try adding it from the Unity Registry in PM

[queen adder]

Yeah i just did that still stuck on 2022s 1.4.4

I dont need to have the 2023 version of the editor installed to have the 2023 vers of these features right?

[rich adder]

no I just showed you works fine on 2021

something wrong with your package manager or something

this should be in #💻┃unity-talk tho

[queen adder]

ok

[desert elm]

is it possible to have something like the SpriteRender.enabled = false be applied to children as well>

[wintry quarry]

Sure - loop over all the renderers and disable them in a loop

e.g.

foreach (Renderer r in GetComponentsInChildren<Renderer>()) r.enabled = false;```

[desert elm]

oh thanks

Don't cross-post, use one channel only!

[polar acorn]

I don't quite follow what the issue is here, what is supposed to be happening?
Also, if you find yourself numbering variables, that is usually a sure sign you should be using a list

[rich egret]

GUN CODE - https://gdl.space/qegisoqihi.cs
**ENEMY CODE -https://paste.ofcode.org/344br3pcPHRXTJY2tHG6ZCu **

THE PROBLEM - The bullets don't hit the enemy, what to do?

[wintry quarry]

Neither of these seem related to bullets hitting enemies

Do you have a script on the bullet perhaps?

Also what components does the bullet have and the enemy?

Also this is weird:

                if (hit.transform.tag == "Enemy")
                {
                    hit.transform.gameObject.GetComponent<EnemyController>().health -= Random.Range(hit1, hit2);
                }```
It seems like you're spawning a projectile but you're also doing this and using a raycast?

[rich egret]

The bullet doesn't have a separate script, I just put a prefab of the bullet and set a shot point.

[wintry quarry]

Which one are you using?

Raycasts or projectiles?

Pick one

[polar acorn]

So, first off, why are you spawning an instance of a prefab, and then adding in a bunch of components to it? Why not just put those components on the prefab

[rich egret]

Sorry I'm a beginner, that's why I came here...

[polar acorn]

Second, log the object your raycast hits. If you're getting bullets to spawn at all, then the ray is hitting something. That thing might not have the Enemy tag

[rich egret]

I thought it would be more convenient

[rich egret]

I tagged it enemy

Does anyone have a solution to fix this? There is no clear enough guide on the Internet

[polar acorn]

Log the object you hit and see if that object has the tag "Enemy"

[rich egret]

I already did that

[polar acorn]

And what did it say

[rich egret]

What does that mean?

[polar acorn]

I literally do not know how to put this any more clearly than asking you what your log said

[rich egret]

ahhhhh

nothing

[polar acorn]

And where did you put the log

[rich egret]

In this part
void Die()
{
Debug.Log("Enemy died!");
// Additional logic for enemy death can be added here
Destroy(gameObject);
}
}

[polar acorn]

That's not what I said

#💻┃code-beginner message

Log the object your raycast hits

see if that has the tag Enemy

[rich egret]

But I already tagged him an Enemy!

[polar acorn]

And how do you know

how do you know that the ray hit that object

[wintry quarry]

You're assuming your Raycast is hitting the enemy. How about instead of being stubborn you actually add logs so you can fix your problems

[polar acorn]

That's not what I asked

At no point did I ask "Is there an object in your project tagged Enemy"

I asked "Is the object your raycast hits tagged enemy"

Now put the fucking log in

[rich egret]

ok

🥲

[rich egret]

and no

🤔

[frosty hound]

@rich egret If you're not going to actual log your issue, as you've been asked multiple times, stop posting.

[rich egret]

@frosty hound 🫣

[polar acorn]

Put in the log.

Show what it prints

Until you do, no one can solve your problem

[meager sentinel]

I place this here since i kinda think this may be via code, but. I have a particle system that triggers when you have contact with an enemy, the thing is, it's supposed to be blood. But if u move when the particle system is working, the blood will stay where you walk, how can i make the particle system to not move after being executed? Or what's the line of code to execute it at a certain location

[polar acorn]

There's a checkbox for something like "Simulate in world space", where the particles are no longer bound to the parent object after spawning

[frosty hound]

Particle systems have a property for simulating in world space.

[meager sentinel]

Thank you both

[rich egret]

I already put it, but I don't receive messages, something is wrong with the script...

[polar acorn]

Where did you put it

[summer stump]

Btw, this
#💻┃code-beginner message
Is NOT what they want logged

They want the RaycastHit logged just after the raycast, before any of the conditions

[polar acorn]

Log the object you hit

then check the tag

We already know this is not running

that's why I told you to log the object your ray hits

not inside an if

[summer stump]

Log the raycasthit (not a random word) "Before" any conditions.

[polar acorn]

just log the object

see what object the raycast hits

[meager sentinel]

Where is it located?

[polar acorn]

Pretty sure it's in main

[meager sentinel]

I opened all of the things and i dont find it

[meager sentinel]

Ohhh Simulation Space

and then u place it on world

ty

[rich egret]

ok like this? @polar acorn

[polar acorn]

how

how did you possibly think this was related to what I asked

[summer stump]

#💻┃code-beginner message

The log should be inside the gun script, just after the line you call raycast. And it should log the object returned by the raycast (called a RaycastHit). You have it declared as "hit"

[polar acorn]

we do not need to print if this object's Update is running. That was never the question. At no point did anyone say anything remotely related to doubting if this object exists.

Log
