Performance wise, they are not too far apart. If u find the built-in object pool too intimidating, I would say practice with the oldschool

[polar acorn]

pooling

[slender nymph]

1. it's pooling not spooling
2. making your own object pool is more complicated than just using the built in one

[tired python]

[hot wadi]

For new dev, I think the built-in pool is quite ambiguous. It hides how the pool internally works, so it may get confusing

[tired python]

you know what screw this, even if it takes me a whole week to implement it i will do this then

[hot wadi]

But basically they are similar. Both use Stack or List

[astral cedar]

how do i get an action map that is not currently selected?

[tired python]

[spring snow]

unity is hard bro

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

public class CusCursor : MonoBehaviour
{
    public bool locked;

    void Start()
    {
        Cursor.visible = false;
        locked = true;
    }

    void Update()
    {
        Vector3 mousePos = Input.mousePosition;
        mousePos.z = 0f; // z is 0 for 2D

        // Convert screen position to world position
        Vector3 worldPos = Camera.main.ScreenToWorldPoint(mousePos);
        worldPos.z = 0f; // make sure z stays 0

        transform.position = worldPos;

    //stops working here
     if (Input.GetKeyDown(KeyCode.L))
    {
        if (locked)
        {
            Cursor.visible = true;
            locked = false;
        }
        if (!locked);
        {
            Cursor.visible = false;
            locked = true;
        }
    }
    }

    
}

litterally everything is working other than the booleans

[slender nymph]

read through this logic and tell me what you think is happening in a single frame here. assume locked == true

if (locked)
{
  Cursor.visible = true;
  locked = false;
}
if (!locked);
{
  Cursor.visible = false;
  locked = true;
}

[spring snow]

the cursor becomes visible and locked is set to false?

[slender nymph]

let's assume i put a Debug.Log call right after that code, what will it print if all it prints is the locked variable?

remember, read through all of the logic here

[spring snow]

think3d it would print either true or false right?

[slender nymph]

what specific value is it going to print

[spring snow]

false

[slender nymph]

incorrect. read through the logic again

[spring snow]

alright gimme a sec

[slender nymph]

(i'll give you a hint, there are two reasons why that is incorrect)

[spring snow]

honestly idk bro

[slender nymph]

read through the logic one line at a time.

[spring snow]

if (locked) //checking if locked is true
{
  Cursor.visible = true; //makes mouse visible
  locked = false; //locked is now false
}
if (!locked); //checks if locked is false
{
  Cursor.visible = false; //hides cursor
  locked = true; // locked is true now
}

[slender nymph]

now that you have those comments there, read through the logic and actually apply those steps in your head

[spring snow]

ok

What i want: if locked = true then hide mouse

line 1. if locked is true then do this
line 2. since locked is true set the mouse to visible
line 3. now the mouse isnt locked

line 4. checks if locked is false
line 5 - 6. if locked is false then hide cursor and locked is now true

i might be stupid

since im running on 3 hours of sleep

but i dont see the issue

[slender nymph]

have you considered continuing through the rest of the code? don't just stop because you think you know the answer, finish evaluating the lines

[spring snow]

i edited it

[slender nymph]

which of the two issues did you fix though (assuming by "edited it" you mean you fixed an issue)

[spring snow]

oh my god bruh

i get it now

its running both lines anyways

i added debug to both if statements and it sets it to false then true

thanks guys/girls

[slender nymph]

yes because they are independent if statements. your second if statement is also unrelated to the block of code below it, but i'll let you see if you can figure out why that is (hint: your IDE should be telling you that too)

[spring snow]

but when i did elseif it came up with an error

[slender nymph]

that's likely because of the issue i just mentioned

[spring snow]

like it didnt exist

is it like else if or elseif

ill try both

[spring snow]

ok

@slender nymph is it because i put a ; which cancles the second if statement

ok imma try without it

yoooo

it works now

yay

thank you

smart

[polar acorn]

What do you need an else if for anyway? What possible value can locked be that isn't either true or false?

[spring snow]

its like a door thingy

i mean it as a metaphor

[polar acorn]

Right so why do you need an else if

instead of an else

[spring snow]

oh

[polar acorn]

What situation could you have where neither code block runs?

[spring snow]

yea i see what you mean now

[spring snow]

nothing

makes sense

thanks

[slender nymph]

even better would be remove the if statement entirely because it isn't really necessary anyway. you can set Cursor.visible to locked and then !locked to locked

and that's assuming you even need the locked variable for something else, otherwise you can just toggle the value of visible

[spring snow]

im gonna understand this

not right now

but eventually

also it's going to be a pause function eventually so i'll just keep it for now

[slender nymph]

let's put it this way, you have a variable that is basically serving a very similar purpose to the property on the Cursor class you are changing. at least with regard to your logic, i understand actually changing that property toggles whether the mouse cursor is visible. but that property also tells you if the mouse cursor is visible or not
and you can just change its value each time you press your input instead of checking what the value is to change it to the opposite of that

[tired python]

so i watched this video again, and i think i know how pooling works. so basically you need to setup four methods:-

1. a method to create objects
2. a method to reenable objects with the right properties
3. a method to deactivate objects based on your needs
4. a method to destroy objects.
   what i don't understand is why is the guy taking _pool references insides the different scripts. i don't get it

[slender nymph]

again, it is pooling not spooling. it's even in the thumbnail and title of that video you linked

[tired python]

sry, i think it's become a bad habit of mine to do that, i just subconciously do it...

specifically from 8:03

whatever he does in the Bullet and BulletSpawner script to set up the pool ain't making sense

[slender nymph]

just keep watching, he'll explain why later

[rocky canyon]

private bool paused = false;

        if (Input.GetKeyDown(KeyCode.P))
        {
            paused = !paused; // flip state once
            // if paused was false now its true
            // if paused was true now its false

            // now we can do the appropriate thing
            if (paused)
            {
                CursorController.Instance.UnHideCursor(); // unhides and unlocks cursor
            }
            else
            {
                CursorController.Instance.LockCursor(); // hides and locks the cursor
            }
        }```
one trick i learned that makes it simple is to flip the boolean first (before any checks)
and then check with an `if/else` so it only checks once..

[slender nymph]

but basically it's so that the bullet can return itself to the pool

[spring snow]

[rocky canyon]

i believe something like that was mentioned up above as well.. just happened to have my code easily accessible so wanted to show the code.. might give u some insight

[tired python]

so...it's because of this which he does in the Bullet script?

at 17:05

do i need to know exactly how it is that the bullets are getting added to the spool?

[slender nymph]

something needs to be able to put the bullet back in the pool otherwise it will never end up back in the pool, which of course would mean using a pool is pointless

[tired python]

oh wait, when he _pools.gets(), that's when he creates a copy or smth?

[languid pagoda]

anyone have any idea what this is?

i have only one editor script using assetdatabase loadasync and its in an editor window that isn't even opened. this ones being called once per frame inside of the PlayerUpdate loop

its causing lag spikes even in an ampty scene I can watch the frames drop from 500 down to 85 for half a second then jump right back up

[stark vessel]

Anyone have a function to take a collider and get all colliders that overlap with the one put in?

[slender nymph]

what kind of collider

[stark vessel]

any Collider type

Im using a MeshCollider if it needs to be one type

but a general method for any Collider would work

[slender nymph]

ah, that's the one that you can't do this for. any other shape would work because of the OverlapXXX methods on the physics class (you don't pass in a collider but it's the same concept)

[stark vessel]

? Is there no method for seeing if a Collider overlaps another Collider? If so, you could loop through all colliders

[slender nymph]

that's what the physics methods are for

[stark vessel]

I wanted Collider not Physics
My object doesnt use physics Im moving is manually

[slender nymph]

by "physics methods" i mean the methods on the Physics class, the ones that query the state of the physics scene to detect colliders in specified areas

[stark vessel]

Is there no method on it that works to let me see if two colliders are touching??

[languid pagoda]

not for mesh colliders

[slender nymph]

are you trying to find out if a collider touches something or are you trying to find out what is overlapped by a collider because those are different things altogether

but yes, there is no method for mesh collider shaped physics queries

[stark vessel]

I want to know either could work, If I know how to check if two are touching then I can make it check for all touching but I'd rather all touching if possible

what is the point of a meshcollider if it cant detect collision also

[slender nymph]

how about this, explain what the actual purpose here is so the real solution can be suggested

[stark vessel]

I want to detect all objects touching my bullet object to damage them

[languid pagoda]

use a raycast

[slender nymph]

that's not even necessary. just use an OnCollisionEnter or OnTriggerEnter

[astral cedar]

why if i add a tag to an object it wont collide with raycasts?

[languid pagoda]

That will not work for bullets

[slender nymph]

why not

[languid pagoda]

They move to fast and they can cross the collider in between physics step

[slender nymph]

then congrats, you get to use the physics queries previously mentioned

[stark vessel]

my bullet is just a prjectile it can move slow (like it dodes right now)

[languid pagoda]

Its pretty frowned upon to use colliders and rigidbodies for bullets

[stark vessel]

im not using a rigidbody

[astral cedar]

maybe this is stupid but you could raycast each frame to the last position of the projectile

[stark vessel]

that wouldnt let my projectile have a hitbox tho

[astral cedar]

i did this in another game engine and worked beautifully but i had to optimize like hell

[astral cedar]

yeah

[languid pagoda]

If you want to use oncollisionenter the object has to be being moved by a rigidbody

so your options are raycast

[astral cedar]

you could use a spherecast to """"simulate"""" a hitbox

[stark vessel]

I thought it just had to be one of them

[languid pagoda]

No the object has to be moved by the physics engine or oncollisionenter will not be called

[stark vessel]

also when did rigidbodies come up im talking about colliders

[languid pagoda]

if you have two objects in the scene with colliders on them the only way physics callbacks will trigger is if the physics engine is moving them colliders are part of physics

[slender nymph]

at this point you've already received your answer, physics queries will do what you are trying to do

[stark vessel]

why is it so hard to detect if two things are colliding

[languid pagoda]

Its not

[stark vessel]

neither object has rigidbody

[slender nymph]

i didn't say anything at all about a rigidbody, did i

[stark vessel]

I thought yall said both needed to be rigidbodies for that to work

[slender nymph]

that was russell who said that about OnCollision/TriggerEnter.
neither of which is a physics query

[languid pagoda]

In order to call oncollisionenter the physics system has to be moving the bullet. So that means either use a raycast like I suggested or use a rigidbody(terrible way to do it)

[warm ridge]

hello guys

[stark vessel]

It isnt a bullet its a projectile

[slender nymph]

how is that relevant

[stark vessel]

So i use a physicsquery to detect all collision objects inside of my Collision object

[stark vessel]

cuz it isnt a bullet??

[languid pagoda]

it doesn't make a difference

everything I said was true

[stark vessel]

ok

[slender nymph]

oh no, someone called your projectile by the name of a different projectile. that means the suggestion won't work

[stark vessel]

i never said that

[languid pagoda]

like bro atp go back to tutorials

read the docs

idk

use a raycast and call it a day

[warm ridge]

im just starting to learn Unity do you have any resource recommendations?

[slender nymph]

or preferably the cast that is the closest shape to the actual projectile

thanks man

[polar acorn]

Why is something small and fast moving like a projectile using a mesh collider? A primitive is probably better.

[slender nymph]

or none at all and only using physics queries

[polar acorn]

And colliders don't really do passive "are these objects touching?" kind of checks. It's an active "I just touched this thing" message.

[slender nymph]

but yeah, primitive would be much better than a mesh collider in this case, especially considering when you move a collider without using a rigidbody it recreates that collider every physics update

[languid pagoda]

if its moving fast it can move past the collider between physics steps youll have inconsistent hit detection if you use colliders for this at all

[polar acorn]

If you set collision detection to continuous you can avoid that, but it requires the bullet have a Rigidbody and is much more expensive than discrete and should probably just be approximated with a physics query

[languid pagoda]

does continous totally remove this issue or just make it less noticable?

[tired python]

so...i tried implementing pooling and i am pretty sure that i am very close to it, thing is, i can't get the ducks to destroy

using Unity.Mathematics;
using UnityEditor.ShaderGraph.Internal;
using UnityEditorInternal.VersionControl;
using UnityEngine;
using UnityEngine.Splines;
using UnityEngine.Pool;

public class enemyAni : MonoBehaviour
{
    // Start is called once before the first execution of Update after the MonoBehaviour is created
    [SerializeField] private SplineAnimate aniSpline;
    [SerializeField] private Animator animator;
    private SplineContainer containsSpline;
    private ObjectPool<GameObject> _pool;
    void Start()
    {
        aniSpline.Completed += onComplete;
        containsSpline = gameObject.GetComponent<SplineContainer>();
    }

    // Update is called once per frame
    void Update()
    {
        if (CalculateTangent() < 0.0f)
        {
            animator.SetBool("isGoingLeft", true);
        }
        else
        {
            animator.SetBool("isGoingLeft", false);
        }
    }
    
    void onComplete()
    {
        //Destroy(gameObject);
        _pool.Release(gameObject);
    }

    public float CalculateTangent()
    {
        float tratio = aniSpline.ElapsedTime / aniSpline.Duration;
        float3 tangentVector = containsSpline.EvaluateTangent(aniSpline.Container.Spline, tratio);
        return tangentVector.x;
    }

    public void SetPool(ObjectPool<GameObject> pool)
    {
        _pool = pool;
    }
}

the part of the code which previously(before implementing pooling) dealt with destroying the gameObject was //Destroy(gameObject). now, instead of the script doing the destruction, i set the pool to destroy it when the time is right

somehow or the other though, it's returning
NullReferenceException: Object reference not set to an instance of an object enemyAni.onComplete () (at Assets/Scripts/enemyAni.cs:37)

where line 37 is exactly where the spool decides whether it needs to destroy some objects off or not

using .Release(gameObject)

[eternal needle]

then _pool is null, meaning you aren't first setting it properly

either you aren't setting it at all or onComplete is running before SetPool

[tired python]

does this mean i am setting pool or not

[eternal needle]

add logs and see exactly whats happening. i did also write "or onComplete is running before SetPool"
throw a debug log in onComplete and SetPool, see which runs first

[eternal needle]

actually I just read it closer, look what object you're spawning and look at what you're setting the pool on.
You spawn a duck yet for some reason reference some enemyani that is unrelated to this duck entirely

[tired python]

does this help in any manner?

the Duck prefab present in heirarchy is the gameobject i am trying to spawn. it has EnemyAni script attached to it. the spawner script isn't attached to this Duck gameobject, instead, it's attached to something else

[eternal needle]

this is your error #💻┃code-beginner message
you just aren't setting the pool on the same object that you're spawning

[tired python]

oh god

[eternal needle]

you aren't getting the EnemyAni script attached to the duck. Look at your CreateDuck() method

[timid saddle]

So I’m trying to figure out how lists work and I can’t figure out how to use them to do what I want. Can anyone help me?

1 - I want to make a list of all game objects with a certain tag that are close and in view of the camera. I know how to check if an object is close and in view of the camera when I have a set GameObject variable I can check, but I don't know how to add multiple objects to a list based on that.

2 - I also need to find which object in the list has the lowest or highest x or y value on this Vector3 “Vector3 directionOfObject = transform.InverseTransformPoint(theObject.transform.position);” which is based on their position, and be able to set a “GameObject” variable equal to that object.

This script is connected to the camera

[viral magnet]

every time i tryto configure VS code it doesnt work

[slender nymph]

https://unity.huh.how/ide-configuration/visual-studio#if-you-are-experiencing-issues

[viral magnet]

i did that

like 3 times

[slender nymph]

i linked to troubleshooting steps for you to take

they will work provided you actually followed the steps to configure it

[shell sorrel]

don't you want to link the VS Code ones ?

[viral magnet]

yep

i use vscode

[slender nymph]

next time you should actually read the page instead of immediately dismissing the instructions without looking and you could have seen it was wrong yourself 😉

[viral magnet]

still doesnt work.

i spent like 5 hours on this yesterday

[slender nymph]

follow the troubleshooting steps

[viral magnet]

in this server

ill send u all the screenshots

its external

i got the thikng

[slender nymph]

have you gone through the troubleshooting steps at the bottom of the page that was linked

[viral magnet]

i deleted scripts with compiler errors

[tired python]

//Instantiating a new duck GameObject
GameObject duck = Instantiate(Duck, Duck.transform.position, Duck.transform.rotation);
Debug.Log("Before setting pool.");
enemyAni enemyani = duck.GetComponent<enemyAni>();
enemyani.SetPool(_duckpool);
Debug.Log("After setting pool.");
return duck;```
so i added this, and the error did seem to not come up but then something really weird happened

[viral magnet]

C# and C# dev kit are both newest version

i have th .NET sdk 9

but it does say this every tim

ms-dotnettools.csharp: Trying to install .NET 9.0.11~arm64~aspnetcore but it already exists. No downloads or changes were made.
visualstudiotoolsforunity.vstuc: Trying to install .NET 9.0.11~arm64 but it already exists. No downloads or changes were made.

why is it arm64?

@viral magnet

[viral magnet]

bro i dont think I can help you

i cant even code cuz my visual studio aint working

[tired python]

i think the ducks aren't being reactivated and that's the issue

[solar hill]

why even ping an individual

also dont crosspost

[solar hill]

you doing pooling? 🤔 send your duck code

[eternal needle]

add more logs until you figure out whats happening exactly. Follow the docs example as well
https://docs.unity3d.com/6000.2/Documentation/ScriptReference/Pool.ObjectPool_1.html

[tired python]

this might be a bit rude of me, but check my previous posts...if you still have further questions, then ping me

[solar hill]

its not rude but i am not that invested so i think ill pass unless something comes up i can explicitly help with lol

[tired python]

aight, i am checking stuff out, currently i have a theory as to smth related to start and update nto working correctly

[eternal needle]

us staring at a video isn't productive, especially when we can't see the full context like when you press space. (nor does anyone want to really go through that).
You should gather the information you can. The only thing I will note though is it does look like the ducks are set active right after being set inactive

[shell sorrel]

so are there errors, or its just not doing proper syntax highlighting and autocomplete

[tired python]

ya, the ducks which do become inactive become active but they don't get animated on the spline

[viral magnet]

it just doesnt give me unity ket terms

should i downlkoad any of these

so like if I press g

it doesnt give me game object or aything like that

it just gives me global

[tired python]

wait a sec, you can't see the debug log pressing space O_O

ahh shiii, discord doing discord stuff

[eternal needle]

well I do see a log for it. it's slightly hard to read considering collapse is on so we can't see the order of the logs. Either way, no one wants to figure out your code flow by staring at a video. This is information you need to provide

[tired python]

oh understandable

[eternal needle]

id really just follow the example closer on the object pool docs, assuming your spawner logic looks different. the screenshot you sent doesn't show most of the methods used in the constructor of the ObjectPool

[viral magnet]

can anyone good at VSC help

[tired python]

maybe check out microsoft's discord or vscode's discord, they might be able to help you

[naive pawn]

with what

have you done the instructions i gave

[viral magnet]

i did

😭😭😭

i told you

i did it yesterday too

i sent you all the screenshots with al the instructions

my C# dev kit doesnt hve any output

[tired python]

i think i might have an inkling of what the problem is. So basically when an object on a spline reaches the end of the spline, OnComplete() gets called once. but what happenss if the same object were to reach the end of the spline, then because of the pooling, it became deactivated and then reactivated. i am assuming, that since it already passed through the spline once, its spline animate isn't gonna work again because it's not in a loop mode...instead, its just a one time thing...

so even though it gets enabled, its spline animate doesn't work because it has already been used once

holy moly big brain moment

@eternal needle @slender nymph @solar hill thx for helping

Hi I'm wondering if there's a way to make this more optimized as my game is running like a potato I think the main cause is the animated wheat being copy and pasted and maybe a way for the scene loading to be faster

[thorn ginkgo]

Good afternoon. I am trying to follow a 2D game tutorial and am having trouble with a tile palette. On the tutorial video, the person added a tile to the palette and it filled the entire grid. However, when I add the image, it only fills up a tiny portion of the grid. Does anyone know how I can get that grid tile filled in? I am on the latest Unity, and the tutorial is from 2022.

I can supply the image png if necessary

[solar hill]

would be a lot more helpful if you just linked the tutorial

[solar hill]

well since the video isnt working, we cant really help but you should use the profiler to diagnose any performance issues yourself

[rugged beacon]

change the sprite unit

[mint flicker]

got it

[solar hill]

the video still isnt playing, at least for me, but what i said earlier still applies...

"you should use the profiler to diagnose any performance issues yourself"

[mint flicker]

oh i will see

[solar hill]

also enable the stats in game mode

[thorn ginkgo]

Here is the link
https://youtu.be/_24TfxaPWlI
You want 27:43 timestamp or so on the video

[rugged beacon]

no, just change the sprite pixel unit

[thorn ginkgo]

Please elaborate

[rugged beacon]

if your sprite 10x10 change the thing to 10

[thorn ginkgo]

It is currently at 100 pixels per unit

What would you suggest?

[solar hill]

probably 10... just like he did in the tutorial

[rugged beacon]

ten billion idk

[thorn ginkgo]

Thank you. That is one mystery solved. I have not fixed the original issue of the fog-of-war not truly working, but I can remove the fog png as a possible cause

[bright wren]

Hi, working on a retro shooter. The tutorial has everything in 3-D. Though the goal is to have billboard sprites for enemies and projectiles just not sure how to swap out the 3-D model with a billboard sprite?

[thorn ginkgo]

Letting folks know, I resolved the problem. I was using an incorrect range in a for loop (typo while following the tutorial)

[teal viper]

Just replace them by hand..?

[solar hill]

replace the mesh renderer with a sprite renderer

thats about it

[spring snow]

is this good for day one progress on scripting? idk i feel like there should be more

[twin pivot]

its very slow at first but once you get over the curve it gets faster

tuff

i see people making games in like 1 month or sum and it looks good but its prob cuz they use premade assets

i use premade assets but its because i cant draw for crap

Hi, I'm using this script to play an audio (using On enter function in insepctor) whenever the character enters a trigger area. It plays sound fine, but problem is, it also plays it when I exit it.

Further, if I assign a function on On exit, it doesn't work.

I am following Prototyping tutorial from Unity. They said if you don't know coding yet, you can use these scripts which would work without any changes.

Is there something wrong with code? Or maybe I'm doing something wrong.

I've IsTrigger checked on for the trigger box:

OnTriggerExit event is never invoked anywhere.. Both on Enter / Exit have the same onTriggerEnterEvent invoked

[candid abyss]

Thanks! It fixed both issues.

Unity tutorial scammed me?

[rich adder]

which tutorial is it ? can you send it

[candid abyss]

The scripts are included in this project (unfortunately you can't see it without downloading). In Step-2. https://learn.unity.com/pathway/creative-core/unit/prototyping/tutorial/get-started-with-prototyping-3?version=6.0

Then later, it says:

We have also created the following three custom script components, which you can use alongside the character controller to handle different interactions. These will give you some flexibility so you don’t have to choose the exact same interactions that we did.

The script I'm using is part of these 3 scripts included in that project. They themselves didn't use it in the project, so maybe not enough users noted the issue.

This is a screenshot of that sample project. I can see that issue here. Looks like the person who created this simply forgot to change that particular statement.

[rich adder]

strange..

[candid abyss]

Yeah. I would have never solved it unless I had started learning basic coding. It confused me for a full day.

I'm almost done with Creative Core tutorials. After that I'd learn some basic coding.

Prototyping is the last tutorial series in that course.

[hot wadi]

The tutorial does not seem to specify the expected behavior

So yeah, take some time to understand how the code should work as u intended

[rich adder]

yeah probably good idea especially the junior pathway, wouldn't hurt to also look up traditional c# tutorials as well.
sticking to the microsoft site mostly, stay away from scammy / poor quality courses on places like Udemy

but yeah that mistake slipped through the cracks, someone rushed it out ? who knows..

[charred bear]

so im just getting started in learning how to code C# in VS 2026 and im following a tutorial from 9 years ago... is there a reason why the references page looks so different? im not sure if he wrote the namespace stuff himself or if it just looks different because of the versions

not to mention im missing "assemblies" from the solution explorer

[north kiln]

Join the C# Discord server, a programming server aimed at coders discussing everything related to C# (CSharp) and .NET. https://discord.com/invite/csharp

[charred bear]

oh im surprised that's a thing

thanks

[hot wadi]

U have all sort of things on discord. Just have to do ur research

[candid abyss]

Is this official or "well-known" C# server if I want to join?

[rough granite]

I mean its server link is called "csharp", its got 60k members, and it went up in 2016 so i would say so yeah

Though if your question is a code problem in unity i would recommend just asking here

Since unity has many of its own libraries

[livid frigate]

my code looks fine right? there isnt anything out of place ive looked multiple times and im having an issue where the animation gets stuck on the last frame after just 1 click

[midnight plover]

is your exit target in your animator set correctly to exit the clip?

[livid frigate]

I'm pretty sure I have a video in #🏃┃animation hold on

#🏃┃animation message

[midnight plover]

lets try not to cross post

[midnight plover]

So from the video, it looks like your animator setup is correct. Are you sure, your atk gets set to false? I do not see any debug.Logs in your code, that would help you to know whats going on

[livid frigate]

@midnight plover this is what happens

it apprently doesnt turn attack 1 to false for some reason

[midnight plover]

Maybe you should try to use triggers instead of bools to trigger an animation

[livid frigate]

yeah ill try that see if that works

[chrome apex]

Let's say I have a complex mesh with a mesh collider and a hole inside.

Can I do a sphere/box cast and create an object with a collider shape of the mesh collider, but only inside those bounds? Or just get the collider somehow without making an object

[livid frigate]

that actually work

thank you so much dude! i love you lol

[trim eagle]

Used Cinemachine FreeLook for my project and its good but because the player movement script uses Input.GetAxis and transform.Translate to move but the jump code uses Rigidbody.AddForce.
And because of that the player jitters when jumping if the Cinemachine Update method is using Late update. And if i change the update method to fixed update player jitters when moving. I managed to"""fix""" this by setting the Update method to Fixed update instead and putting the movement code (Input.GetAxis and transform.Translate) in to Fixed Update()
I was wondering if its bad putting the movement code (Input.GetAxis and transform.Translate) to Fixed Update()

[patent vortex]

If the movement has Physics related, it is legit to put in FixedUpdate

[tender mirage]

Fixedupdate was made for physics. it's ideal to use that for physic related code.

It behaves differently then update in more then 1 way as well, if i recall.

you'll have less problems using the correct one for their intended purpose

[naive pawn]

Input.GetAxis is somewhat bad to put in FixedUpdate. input is framebound.

you're using transform.Translate on a rigidbody? that's wrong, you'll be fighting the rigidbody and you'll have desyncs

the jitter is probably from that

input should be taken on Update
continuous input (ie "is x held down") could be in FixedUpdate
addforce should be in FixedUpdate
instantaneous forces could be in Update

[viral magnet]

hi

can anybody help with this error message

InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings.
UnityEngine.Input.GetKeyDown (UnityEngine.KeyCode key) (at /Users/bokken/build/output/unity/unity/Modules/InputLegacy/Input.bindings.cs:418)
Bird.Update () (at Assets/Bird.cs:17)

i can provide my script if necessary

i think its because im using legacy code

[midnight plover]

you are basically using "Input.GetKeyDown" or similar, but you are using the new input system. So you have to use the syntax and code for that

[viral magnet]

yep

so whats the new input system

can you tell me pls

i swtiched to input system package to both

[midnight plover]

Google will tell you for sure

[viral magnet]

i switched to both

[midnight plover]

does your playersettings say both?

[naive pawn]

!input

[radiant void]

How to Set Input

To set Active Input Handling, go to:
Project Settings > Player > Active Input Handling

• Input Manager (Old): Use the original Input settings.
• Input System Package (New): Uses the new input system package.
• Both: Use both systems.

[soft stone]

I have made a small unity project for my college submission, but when my friends try to download the exe from the google drive, It shows an error, UnityPlayer.dll Not found... How do I fix this?

[frail hawk]

is that a coding question?

[soft stone]

Look I didnt find any other channel that specifically targets this error, Would appreciate if someone helps though

[frail hawk]

#💻┃unity-talk

[hearty girder]

Hey,

I have downloaded unity like a hour ago and started following a tutorial to get to know the basics and in the tutorial they used addforce to a object to move it left and right but when i press D the force does not get added. has there been a update or something?

[astral cedar]

this is what your game build should look what the console says? also i think is because you are using a deprecated version of the input system

to make sure it works add a " print(Input.GetKey("d") " above the if statement to check if the input is really the problem

[hearty girder]

ahh i get this error

[astral cedar]

yeah thats what i thought

[ivory bobcat]

Are you using the old input system? Also acquire input in Update and evaluate it in fixed update

[hearty girder]

I think i am

[astral cedar]

you should switch to the new input system instead, but it takes way longer than you think

[hearty girder]

Is there a tutorial about how to use the new input system?

[astral cedar]

ill send you the one i used

[hearty girder]

Alright

[frail hawk]

whatever tutorial you are follwing there, please stop wasting your time with it

they are not even making use of Axis

[hearty girder]

Its a tutorial from 8 years ago 💀

[frail hawk]

yep i can see that

i´d highly recommend you learn the new input system instead, along with how to use axis

[astral cedar]

https://www.youtube.com/watch?v=ONlMEZs9Rgw this one explains everything about it, its very useful for me and the guy explains it very well

[hearty girder]

Alright

I am studying software development and next period i am going to learn game development in unity so i already wanted to take a look at it and learn a bit.

[frail hawk]

sounds cool.

[astral cedar]

actually same, i always wanted to make an unity game but i was 11 the first time i used it, and my english want good either, so i learnt Roblox studio for 5 years and now im here

[hearty girder]

is the new movement system default or do i need to install it like the video?

[astral cedar]

you need to install it

[hearty girder]

Alr

[crisp quest]

why it is looking strange and how to fix this?

ping me if someone answer me

[frosty hound]

You're in ISO view, click the button under the transform gizmo at the top right.

[crisp quest]

What is iso view could you pls explain in simple words ?

[astral cedar]

how do i add delay to the code?

[frosty hound]

It's an orthgraphic projection where there is no depth.

It's useful, in this case, for aligning things.

[astral cedar]

like Sleep() or Delay()

[frosty hound]

You either use a coroutine which lets you yield to time, or you track time in your Update function and do something when it surpasses an amount.

[astral cedar]

so i should stick with time1 - time2 if i dont want to use coroutines?

anyway im gonna check what are those

[frosty hound]

I don't know what time1-time2 means, but if you don't want to use a coroutine, then you need to track the accumulated time manually yes.

[astral cedar]

something like this. btw i cant use coroutines in the Update functions, and because i lack of intellectual skills i will stick with this method. thanks anyway as ill learn how to use those in future

[frosty hound]

By the way, if you're using time to buffer something like that, that's going to be bad news in the future.

Why do you need to wait 3 seconds to start the game, for example?

[astral cedar]

i just made this example to show you, i dont really know too

[astral cedar]

i really didnt knew any other way and i used this method in other game engines, as some people said this was an accurate method

so i just get used to it

[brave robin]

Another would be to add Time.deltaTime to a float in Update, and check if that exceeds your target duration
Time.deltaTime is the amount of time spent in the last frame

[astral cedar]

that would work too

maybe is even less complicated

[round coyote]

Hi, I need help. I’m making a cleaning game, and I’ve projected stains onto the ground using a Decal Projector. However, I don’t know how to clean them realistically, like erasing a drawing inch by inch so it actually feels like cleaning.

I tried using Shader Graph, but I couldn’t figure out the correct way to implement it, and I ended up failing. Can someone please help me understand how to properly create this cleaning mechanic?

Thanks in advance!

[eternal needle]

this isn't something i've done myself but i'd imagine you'd really just want to SetPixels on the texture of whatever object you're cleaning. this should fall under anything "drawing on objects" related when googling

[round coyote]

Okey I try this thanks

[flint wind]

Hello, I’m having an issue with the playable director. I have it set to after one playable director finishes playing, another one plays. But the problem is that for some reason, the wrap mode for one of them keeps setting itself to hold in play mode. even after I set it as none in the editor.

[fierce junco]

hey i am making a multiplayer prop hunt game in vr on unity does anyone have like a tutorial or code or smthin or maybe make a video on how to

[astral cedar]

like a tutorial for the full game?

[fierce junco]

like of how to set up like a prop hunt gun

[astral cedar]

you could raycast to an object and then copy its mesh and size

[charred monolith]

I am looking for a way, that if a metor hit the objects, that the objects moves faster away because it just looks more realistic. but idk how to do that. please help
https://paste.mod.gg/hwnjekldyzfv/0

[astral cedar]

you could make that the collided objects will fly away to the same direction of the meteor and that object, and then multiply the velocity by the meteor magnitude

also just for curiosity, are you willing to make this multiplayer or a sort of simulator?

[fierce junco]

how would i set that up

[astral cedar]

do you have a snippet?

[charred monolith]

i will prob make this multiplayer soon

[fierce junco]

whats that

im quite new to unity

[astral cedar]

a piece of code

[fierce junco]

ive only started recently

[astral cedar]

btw you should create a raycast hit variable, then do an actual raycast and store that in it (by doing Physic.Raycast(position, direction, out variable).

then get the game object and from here get the material/ mesh component

if you dont know how to code it then you should look for both raycasts and components tutorials

[fierce junco]

what should i search to find the right tutorial

[astral cedar]

components are a bit generic so any tutorial (even about specific things) should be okay, and for the raycasts just search a raycast hit tutorial

[fierce junco]

when i watched a tutorial it mostly just talks about using it to make wall collision

[rich adder]

This requires years of experience..

[frosty yarrow]

um you shouldn't make movemnt in this way like this your game will be cooked use the new input system or use input.getaxis("Horizontal");

[hearty girder]

Yeah already did that

But thank you

[frosty yarrow]

oh okay great job but fact never give up whatever you stuck with ask me or anyone you know here because unity is not easy + do a tutorial game found in youtube do 2 of them then start with simple games untile you start with you dream game and learn more while you are working

[hearty girder]

i am now trying to add a animation 💀

[frosty yarrow]

need help ?

[hearty girder]

Maybe layer i wanna try first

Been playing with rigidbodies and could use some info on some things.

1. In real life, static friction needs to be overcome for an object to move. As far as I can tell, with a high mass rigidbody with a super high static friction value, it still moves when pushed by another object, albeit very barely. Maybe that's a code issue on the pushing side of things? Not sure, the static friction values are stupidly high rn.

2. What goes into creating different speeds of descent from gravity with rigidbodies? I can have two objects with mega different masses and they fall at the same speed.

[mystic flume]

anyone know to get rid black box that deletes letters after i backspace

[sour fulcrum]

insert key toggles that

Anyone know what clampmagnitude does because i can not understand it.

[rich adder]

it "clamps" the magnitude (the length of vector) to a certain number

its doing some" heavy lifting" math for you
all in relation to Pythagoras, trig and unit circles

Vector2 v = new Vector2(4, 4);
Vector2 r = Vector2.ClampMagnitude(v, 2);
// r ≈ (1.4142, 1.4142)```
so like it normalized then x max

[rough granite]

My god insert key bullied me for about a year of on and off existence before a friend noticed i had it on and called me insane and i was like idk how to turn it off/on it just happens

[spring snow]

is this a efficient way to learn c#

1. See something i want to make
2. use tools like youtube, reddit, chatgpt
   3.remake the system but don't use any tools and go by memory
3. when i get stuck i focus on learning that specific thing
4. repeat

[rich adder]

use tools like youtube, reddit, chatgpt
not really, everything else should be acceptable

[waxen adder]

I roughly do that. I come from a modding background, so having the ability to sit down and look at existing stuff is really nice. From there, I try to piece together how it all works and customize from there

Usually with chatgpt responses, the final script is completely different because of my own programming preferences. Occasionally it spits out something that I like first try

[spring snow]

wdym

don't use tools?

[rich adder]

youtube is ok if you find right courses.. but mainly you should avoid reddit / gpt (its mostly where it scrapes data anyway)

[spring snow]

yea i only use chat gpt to explain specific things like "how to make a raycast" but not an entire script

[spring snow]

ok what about like just looking up how to use apis and stuff, what would be the best place for that

[rich adder]

google / research, filter out your results to confirm accuracy

don't blindly trust what a chatbot spits out

[spring snow]

when you mean filter do you mean trying to get the same answers from multiple sources

[rich adder]

yes

[spring snow]

ok cool

im just learning how to script enemy ai now so i'm getting into the deep side of c# and i want to make sure i learn the right way so i don't need to struggle learning better ways in the future

[rich adder]

what you mention doesn't sound c# specific, there is a distinction between Unitys API and C#

C# is the core language, unity just uses it for api to talk to the c++ engine

[spring snow]

so like how luau (roblox) is to lua?

ehh makes sense i guess

[waxen adder]

If you wanna start really basic, start with just some sort of MoveTowards for the enemy ai. Don't account for obstacles. From there you can dive into navmeshes, raycasts, etc.

[spring snow]

ok thanks

[waxen adder]

I think there's literally a MoveTowards function for transforms right?

[spring snow]

i'm just doing a binding of issac remake prototype for now

[spring snow]

i'll look and see maybe

[waxen adder]

SAME XD. Trying to get the movement right. It's kind of actually deceptively hard to implement in unity

Since there is some physics to his movement

[rich adder]

hmm not sure I would exactly say that cause its considered a seperate language even if dervied from lua

[spring snow]

might be unoptimized but i just used input.x and input.y

[spring snow]

so like more tamer than luau is to lua

[rich adder]

there is no "unity c#" only specific concepts of unity like Gameobjects etc. but its still c# classes and all

if you want to know c# properly use something like microsoft learn site or others like w3schools. Break down the bigger /specific problems into simpler to solve generalized ones

and always check Unity docs for unity specific things

[waxen adder]

The issue I'm running into is that enemies can push him and vice versa, which calls for a rigidbody, and yet his final movement in normal scenarios leads to a final top speed, which a rigidbody fights against due to how gravity works. Could just turn gravity off tho

[spring snow]

alright

[spring snow]

yea i just turned off gravity cuz i don't want to deal with the harder ways of doing a top down

[waxen adder]

Oh did you do rigidbody too?

[spring snow]

i'm currently trying to figure out how to change public varibles from a raycasthit2d

[spring snow]

i think lemme check

[spring snow]

like

shoot raycast and edit component in whatever the raycast hit for damage and stuff

[spring snow]

yea i did rigid body dynamic and just turned off gravity

[rich adder]

thats what literally Get/TryGetComponent is for

[waxen adder]

Ah nice, sounds like my head was in the right place after all XD
Kept dancing between that and a CC

[spring snow]

i will look into it

[rich adder]

the raycasthit gives you the collider of object you can search that component on

[spring snow]

great minds think alike

[spring snow]

alright thank you

i'll come back once i get this working

[rich adder]

Hello everyone, i was just completed building my unity project but mistaakenly i deleted few files which contained the Materials files which are supposed to give colors to the object, can someone please help fixing it

[rich adder]

this is not a code question

dont crosspost

[astral cedar]

wrong channel but deleting a file cant be restored

[spring snow]

got it working thanks

    void Shoot () {        
        Debug.Log("Shooting raycast...");
        RaycastHit2D hit = Physics2D.Raycast(transform.position, transform.up, 1f);

        if (hit){
            Debug.Log("Something was hit");
            Debug.Log(hit.collider.gameObject.name);

            GameObject hitObject = hit.collider.gameObject;
            Enemy enemyScript = hitObject.GetComponent<Enemy>();
            if (enemyScript != null) {
                enemyScript.CurrentHealth -= 1;
                Debug.Log("Enemy health: " + enemyScript.CurrentHealth);
            }
        }
        else {
            Debug.Log("Nothing was hit");
        }
    }
}

ill change the music eventually

[rich adder]

sure not a bad start, some of the code is redudant

[spring snow]

hmm let me try cleaning it up then

[rich adder]

if (hit) {
    GameObject hitObject = hit.collider.gameObject;
    Debug.Log($"{hitObject.name} was hit");
    if (hitObject.TryGetComponent(out Enemey enemy)) {
        enemey.CurrentHealth -= 1;
        Debug.Log($"Enemy health: {enemy.CurrentHealth}");
    }
}```

[spring snow]

ts doesnt exist

delete it before i read it

[rich adder]

the what now?

[spring snow]

the code

it was a joke kinda

im trying to figure out how to optimize it myself so im not reliant on other sources of code

[rich adder]

hmm.. as long as you didn't use gpt to write it in the first place

[spring snow]

no bro

only a yt tutorial on raycasts and unity docs

the links you sent

[rich adder]

just wanted to point why those changes might be better afterwards thats why.. it could be self explanitory but importantly try to avoid for example redudant / writing things twice

[spring snow]

ok im almost done and ill show you

[crisp quest]

whats the prob?

[rich adder]

you should probably clarify whats expected vs whats happening

also wassup with those very specific decimals 😵‍💫

[spring snow]

he might be making his own pi or something

also is this good optimization?

    void Shoot () {    
        RaycastHit2D hit = Physics2D.Raycast(transform.position, transform.up, 1f);

        if (hit){
            Debug.Log("Hit:" + hit.collider.gameObject.name);
            Enemy enemyScript = hit.collider.gameObject.GetComponent<Enemy>();
            if (enemyScript != null) {
                enemyScript.CurrentHealth -= 1;
                Debug.Log("Enemy health: " + enemyScript.CurrentHealth);
            }
        }
        else {
            Debug.Log("Nothing was hit");
        }
    }
}

[rich adder]

looks the same to me...

just study the one I sent and then compare

[spring snow]

ok

[rich adder]

sure you don't need hitObject but the point was not to repeating the thiing twice in both the log and access component

[spring snow]

what does the dollar sign do in Debug.Log($"{hitObject.name} was hit"); and Debug.Log($"Enemy health: {enemy.CurrentHealth}");

[rich adder]

thats important, so when you change one you don't have to remember to change it at every spot, thats why variables exists

[rich adder]

its called string interpolation

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated
avoids having to use + every time you want to add variables to strings

[sour fulcrum]

Type myInstance = gameObject.GetComponent<MyType>();
if (myInstance != null)
    //Code using myInstance

and

if (gameObject.TryGetComponent(out MyType myInstance)
    //Code using myInstance

do the exact same thing btw, the latter is just a cleaner way of writing it

[crisp quest]

i want a script which can follow my target and when i press right mouse button then my camera moves to the face of my obj (like in fps shooter game, we aim by pressing right mouse button ) but it is just following my player and when i press rightmouse button then it just flickers

[spring snow]

ok last question, i understand the first one, but what does (out MyType myInstance)
do? i know ur defining varible but idk what the out has to do with it

[rich adder]

ButtonDown is a one frame event

you are like teleporting a camera each time you press and it pressed done

[waxen adder]

It's like a return value.

Out parameters for functions can be used in the code of the caller.

[rich adder]

out is basically useful when you need more than 1 value returned by a function without changing return type

[spring snow]

so it merged the defining varible and the if statement lines so now nothing else matters except if the raycast hit the varible

[rich adder]

the function TryGetComponent returns a bool, so if it found it puts the component in a variable through the out

[spring snow]

[spring snow]

ok this is valuable information

thanks guys

im gonna figure out how to do enemy movement myself with MoveToward but thank you for helping me understand stuff

[rich adder]

might wanna start look into navmesh 2d by h8man or learn basics of a*
or use A* pathfinding project

MoveTowards works for very basic things and usually teleports through solid

or gets stuck if you got rigidbody on it

[crisp quest]

then what do i have to do ?

[rich adder]

still not sure why you want to move the camera, fps usualy dont move the camera to aim

rotating mainly

[spring snow]

aight

[crisp quest]

ummm i guess you dont get it , i want to make smtg like when i click RMB then camera changes its position on my desired place

i guess it is simple explanation

[waxen adder]

Oh is the mouse free during this?

Like can it move normally on screen?

[crisp quest]

camera is following my player

[rich adder]

it moves but the next frame is going to go back right away

it happens quickly

KeyDown happens in 1 frame

then runs else right after

[crisp quest]

see this

[crisp quest]

then what do i have to use to make it like when i click RMB then it just goes to my desired camera position ?

[rich adder]

its doing exactly what I described lol

[crisp quest]

yeaaa

[rich adder]

its going to your position

thats why it helps to explain it better what you want to do

if you want it to stay there then you cannot use that else statement on the next frame

but again hard to tell a solution if you don't explain what the mechanic is here , it may even exist a better way than whatever it is you're doing now

[crisp quest]

i want my camera to summon on the "X" given in the image whenever i click RMB and switch to its normal position (where it is following the object)

[hallow sun]

use GetMouseButton instead of GetMouseButtonDown so that it lasts as long as you hold the button instead of just the first frame

if its supposed to be a toggle then use a bool and make GetMouseButtonDown switch its value

[crisp quest]

ok i'll try

[crystal heath]

Is it worth using Cinemachine for a first-person view? I want to smooth the camera, and it seems easier with it.

[twin pivot]

yes

[crystal heath]

Alright, I give it a try 😄

only thing scares me is i have to use an empty game object as target

[rough granite]

Curious of the times where people would recommend not using chinemachine its a full system to control the camera and you dont need to do anything

[midnight plover]

Its like with everything, that is pre setup to cover a lot of control, you can get a hard time to get special behaviour out of it. Like with every package, there are pros and cons on how much you wanna be tied to that system.

[crisp quest]

i wanna learn cinemachine but i want a proper guide to learn it . i guess it is used by everyone now and i have to learn it now ,

[midnight plover]

Arent there some tutorials by unity directly? did you check the learn page?

!learn

[radiant void]

:teacher: Unity Learn ↗

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

[crisp quest]

nope , does it have special section for cinemachine?

[midnight plover]

Imagine there was a search engine on the web... https://learn.unity.com/project/working-with-cinemachine-cameras-2019-3

[crisp quest]

wait....what.....its whole damn tutorial and im here crying about it and experimenting

[midnight plover]

It might be outdated at some points, but should still be valid for most parts

[crisp quest]

hmmm outdate is just the changed its position on UI , lol

[hexed terrace]

there's quite big changes between cinemachine v2 and v3

[nimble apex]

after doing research i found out making my own GUID for asset referencing is still the best solution, because its very stable and compatible, so im heading back to my own custom GUID system again

this is more of an editor UI optimization problem, how can i automatically generates the string (or key of the dictionary) when i try to add element on inspector?

because by default it wont generate itself right?

[midnight plover]

OnValidate?

[nimble apex]

thank you

👍

[undone wave]

just to be sure, this "new List<>()" doesn't cause any data leaks, right?

collider2d.Overlap(new List<Collider2D>()) > 0

[naive pawn]

managed objects usually won't, sure

i don't see the point of it though

[undone wave]

apparently the Overlap function doesn't work unless I add that

[naive pawn]

yeah, but why not have it as a member so you don't have to construct a new one every time

[undone wave]

I just didn't have any use for the results so I added that as a temporary workaround

[naive pawn]

fair enough, i guess

[undone wave]

Is it "better" to just have it as a member?

[lyric rapids]

Hi I have small problem understanding unity, we got an app made in unity from different comapny. I have an template of a dropdown list, I see it's posisitoned around center of the screen and it has anchor to top center of it, but dropdown renders in the top of the screen not the template. Doesnt matter how I change the anchor, dropdown always renders in the same position

I can see that instead of top being 1450 its bottom 1450

[gloomy heart]

Set Dropdown Template's Pivot Y = 1 (top) Reset Anchored Position Y to 0

[lyric rapids]

Anchored position is 751 right?

[gloomy heart]

that's fine, Now just move the whole DropdownObject where you want it on the canvas and test it

[lyric rapids]

It still goes to the top. Maybe Ill show my hierarchy

Dropdown is deleted from the scene the second I click outside of it

And is created when I click Input 4

I guess pressing on Dropdown visible under Input 4 creates new template

GameObject* based on the template

Okay, I had to put template under this Dropdown and play with Y and Pivot, thanks a lot

But now I have different issue, every now and then Unity shows loading bar, after it it shows pop ups like if it just opened (MCP server and some package info) and it crashes my app with these logs

[thorn yacht]

@sour fulcrum Enemy enemy = Instantiate(creeperPrefab, creeperSpawn.position, creeperSpawn.rotation, transform); activeEnemies.Add(enemy); enemy.BeginCreeping();

the creeperPrefab is assigned via inspector

[sour fulcrum]

this is how you post c# snips on discord btw

[thorn yacht]

I double click on the prefab that's in that field, and its walkSpeed is 0.6f

[sour fulcrum]

debug log creeperPrefab's walkSpeed before the instansiate line

and debug log enemy's walkSpeed after the instansiate line

[thorn yacht]

Good idea

Both values say 1.2f

[sour fulcrum]

well something is up with this statement

gives prefab override energy related stuff but you'd have to provide more screenshots etc. if you need help narrowing it down

[thorn yacht]

I changed absolutely nothing other than removing the prefab from the inspector, and re-adding the same prefab from the project window to it

And now it has the correct value of 0.6f

Do changes made to prefabs not take effect unless you remove and re-add the reference? I thought the whole point of prefabs was to not have to do that

[earnest ibex]

where can i ask for help?

[sour fulcrum]

that is not something that exists no, what your experiencing for some reason is unexpected behavior

[thorn yacht]

That's why I was confused haha

[sour fulcrum]

(as in something you've done has caused this accidently, not that its a unity fault)

can't say forsure what happened

[sour fulcrum]

but simple debugging like this helps narrow it down fast

[earnest ibex]

?? please im desprate XD

[thorn yacht]

Yeah, I need to debug things more, tyt

[frosty hound]

You need to ask a question, not bait people into helping you.

[earnest ibex]

sorry

im like really new and need some help, my 2d player keeps spinning when it goes into walls

how do i like stop that

[gloomy heart]

colliders, and possibly freeze that axis rotation if not needed

[earnest ibex]

guys i want to switch my camera in between by pressing a specific button with using cinemachine in my 3rd Person shooter game . how to do it?

help please

[gloomy heart]

you can create a custom script which switches between em'

[crisp quest]

i did but i wanna learn to switch using cinemachine

[limpid thistle]

Why cant i move this file?

[gloomy heart]

it might be locked by another process

[crisp quest]

click Cancel, then try moving the folder again from the Project window, not from Windows Explorer, maybe3 it will help

[hexed terrace]

that is in Unity, not windows explorer

[earnest ibex]

my move tool has theese arrows, how do i make it move freely again?

like the X and Y arrows (im working in 2D)

[gloomy heart]

what?

[earnest ibex]

like its

idk i pressed something now it uses those arrows where i have to go updown then left right instead of moving the sprite freely anywhere with my mouse

[gloomy heart]

look for toolmode toggle or check gizmo

[earnest ibex]

thanks

[tame juniper]

Hello, im making some UI for my game, and am trying to put a shadow image beneath the ui button, but also be a child of the object, how can i do this?

[tame juniper]

oh, didnt know that existed, thanks!

it works

[gloomy heart]

yay!

[tame juniper]

this is unrelated, but while coding in unity, i randomly get this thing where when selecting, it replaces the current character ive selected, instead of your normal add a letter next to it, anyone know what im tlaking about?

[gloomy heart]

i don't get it

[cosmic dagger]

Press the insert key to switch it from overwriting the character . . .

[tame juniper]

where is that 😭

sorry im dumb

oh wait

hang on

[cosmic dagger]

above the arrows on the keyboard . . .

[tame juniper]

omgah thanks

is that just a thing in general and not in unity

[cosmic dagger]

yes, it's not unity-specific. just normal . . .

[tame juniper]

lel my bad

well thanks though it worked

[stark vessel]

is it normal for rigidbody objects to float above the ground? Because my player is like half a unit above the floor and it really messes up the game because I don't want my player half their height in the air

[keen dew]

Why would it be normal

Either your setup or code is wrong

[stark vessel]

only happens if i make my own gravity

wait

[cosmic dagger]

You'd have to explain what you mean by that . . .

[stark vessel]

I think my raycast was too long

[polar acorn]

So then whatever you're doing to detect the ground is probably incorrect

[stark vessel]

my playet thought it was on the floor oops

[gloomy heart]

i think your colliders are slight bigger

[stark vessel]

yes thats what I said

now I must figure out the mystery of why in the world my player is bouncing... do the physics modify the force when an object hits a floor or wall?

[gloomy heart]

physics material maybe

[stark vessel]

How do I change that theres nothing mentioning a material on this rigidbody thing

its a separate component aint it

no?

[frail hawk]

what are you even asking?

[gloomy heart]

The Physics Engine looks at the Physics Material attached to that Collider

[stark vessel]

ohhh tehre it issss

[sour adder]

Have you checked Physics->Contact Offset?

[stark vessel]

no bounce, and yet my player still boUNCESSS

[stark vessel]

i fixxed that, my floor detecting raycast was half the player too long

[keen dew]

If this again happens only with your custom gravity code and not with the default setup then it's again something you've done wrong in the custom code

[stark vessel]

I removed custom gravity and friction altogether im gonna let unity do that

I STILL BOUNCE I SET BOUNCINESS TO ZERO WITH MINIMUM BOUNCE??? WHERE IS THE BOUNCE COMING FROM??

also friction is at 99/100 WHY AM I NOT EXPERIENCING FIRCTIONNNNN

this isnt scripting

gonna go to the physics channel

[astral cedar]

did you restart your pc and asked nicely?

[stark vessel]

|:

[polar acorn]

How are you moving the character?

[stark vessel]

gravity

rigidbody

[polar acorn]

That doesn't answer the question. By which method are you making the character move

Are you setting velocity, using moveposition, or add force?

or something different entirely?

[stark vessel]

moveposition

[polar acorn]

So, you're giving it a specific position to move to every frame. Are you factoring in friction into that math?

[stark vessel]

no

[polar acorn]

So that would be why you're not getting friction

[stark vessel]

I use the material's friction

[polar acorn]

Teleportation notoriously does not respect the laws of physics

If you want realistic physics, you're going to need to use realistic movement, meaning AddForce

[stark vessel]

Oh ok

so far my movement doesnt work ): im gonna get that fixed

and then everything ekse

its my friction isnt it

[frail hawk]

use a proper physics based movement

[stark vessel]

I am

[polar acorn]

MovePosition exerts forces, but doesn't respond to them. It's so you can have a more specific point-to-point control while still being able to push and collide with things

[stark vessel]

im not using that

im using AddForce

[polar acorn]

Yeah, that will let you get some friction from the object that you're colliding with

[stark vessel]

yep 👍 now I need to make my player actually nice to control

especially mid air

I want the player to have a lot of friction but for friction to almost fully go away when I am trying to move

[crisp quest]

what is wrong with my code ? why it is not working?

[frail hawk]

could you tell us what pdf means

[crisp quest]

oh im sry it was my mistake

[frail hawk]

and now tell us what is not working.

[crisp quest]

i want my camera follow my mouse and i have made this script(mentioned above) but is is not working

someone help please

Xcursor and Ycursor is storing them and they are floats

you override them every frame

yes, you should provide code properly

[crisp quest]

should i paste it here in this chat?

or wht

[naive pawn]

formatted properly, sure. or, since you're asking about quite a large chunk, see the "large code blocks" section

[crisp quest]

i clicked one of the link and pasted my code there and now?

[round citrus]

so im making this galaga "remake" thing for a school project-like thing. any idea why the projectile prefab only spawns like 1/15 of the time when i press the button to spawn it? (movement.cs is for the player character, being where the projectile spawns at, and bulletmovement.cs is pretty self explanatory

ill try to record it in a sec

clicking as fast as i can here

[frail hawk]

you have the user Input inside FixedUpdate, that should be the reason why your Input is not being detected every frame

[round citrus]

code's probably pretty messy as its basically just a concoction of code from different tutorials but yeahhhhhhhhhhhh

[round citrus]

movement script works fine while also being in fixedupdate though, where should i try moving it?

[frail hawk]

movement also doesn´t work fine but you just don´t notice it because it is not as frame dependent as the instantiating method. You´d change it to Update() instead

[round citrus]

so changing FixedUpdate to Update, or making a new group or whatever its called?

[crisp quest]

Sir is this fine now?

[frail hawk]

we need to see the whole script as code

Use links to services like:
https://paste.mod.gg/, https://hastebin.skyra.pw/, https://paste.ofcode.org/, https://paste.myst.rs/

pasteofcode is cool

[crisp quest]

i dont know how to use

[stark vessel]

is there a good way to apply friction on my own? with code? I want to make it so I slow down faster when I stop walking

[frail hawk]

just click on the link slap your code into the empty field select c# and paste, then share the link

[crisp quest]

https://paste.mod.gg/jwvdlncbgcoc/0

this is my script

[frail hawk]

yeah kind of but it is confusing that you use 4 floats. you only need Xcursor and Ycursor

Xcursor += MouseX
Ycursor -= MouseY

[stark vessel]

how do I apply friction with code

[frail hawk]

and multiply theem with a sensitivity float of choice

with the king float which is in your case 1 and doesn´t make sense but ok

[crisp quest]

do i have to do this rather than, yak += Xcursor;
yawn += Ycursor;, it is more efficient?

[frail hawk]

yeah declare these 2 floats at class variables as you have yawn and yak

you want to keep these values outside of update method

[crisp quest]

like Xcursor += MouseX * 4f; (for example)?

[frail hawk]

for example yes, but i used pseudo code, do it right

[crisp quest]

i didnt get your these things you said (my english is weak , sry)

[crisp quest]

okay sir , i will try

[frail hawk]

can you show your current code

[crisp quest]

it is same as before , i didnt change anything cause im understanding by you first

https://paste.mod.gg/jwvdlncbgcoc/0

still take it (it is same)

[frail hawk]

https://paste.ofcode.org/ryEvSX8PvWfCcG34gMGcnQ

we also need to clamp the Y axis

[stark vessel]

is there a way to make my horizontal movement be capped

[frail hawk]

what do you mean by capped?

[crisp quest]

sir ive a question that why did you do [ Xcursor += Input.GetAxis("Mouse X")*king;
Ycursor -= Input.GetAxis("Mouse Y")*king; ]? like you did += in mouse x and -= in mouse Y

reason?

[frail hawk]

so you can store the value and add current value to it

[crisp quest]

ummm i guess i need a tutorial just to undrstand this " += and -+ "things

[frail hawk]

is it working now or not

also these are c# basics
myFloat += value is same as myFloat = myFloat + value

[crisp quest]

nope

[frail hawk]

do you have any errors in your console you are using the old Input class

[crisp quest]

camera is following but not moving as we want

[crisp quest]

nope i have changed it to "both "earlier

[frail hawk]

yeah but we did not touch any of the moving code , you only wanted the rotation

why not use cinemashine actually

[stark vessel]

X+=Y means X=X+Y

[crisp quest]

yea and given code by you is not working too

[frail hawk]

you said it is rotating so it indicates that it is working

[crisp quest]

i want to use cinemachine but it is too complex for me to understand or you can say that i dont have anyone to teach me or guide me towards it , i tried it before too but i had hard time doing what i want from it so

[frail hawk]

take a look at cinemashine it is really powerfull

[crisp quest]

i have seen people using cine so easily and when i get motivated and when i open it , it looks like a mess to me so my brother and one other person on different server suggest me to do it using code

[round citrus]

also while im here, how do i make it so the movement is at a constant speed instead of accelerating when pressing down, and deaccelerating for a bit when pressing off?

trying to make the movement more accurate to the original

how do I multiply only the x of a vectorrrrr

[round citrus]

thanks

[crisp quest]

suggest me some guide for the cinemachine

[frail hawk]

use a new Vector3 feed your values in and edit the x

[crisp quest]

it is really hard and complex for me to understand

[frail hawk]

#🎥┃cinemachine it is time to switch the channel

[slender nymph]

there are guides and documentation pinned in #🎥┃cinemachine

[crisp quest]

Vector3 v = new Vector3(1f, 1f, 1f);
multiply just the X value
v.x *= 2f;
v.x is the X part
v.y and v.z stay exactly the same

ig taht is how it is done

im now watching and it worked btw so nvm but thank you

If I have a scene with objects laid out in front of a perspective camera like this, with their local forward vector pointing about- How can I take that forward vector and convert it to a 2D one from the camera's perspective? So it's described exactly how I see it on the flat screen? Green is up, red is mostly to the right, blue is between them etc etc?

[keen dew]

WorldToScreenPoint from the object position to its position + right, up and forward

[candid anvil]

french ?

[plain hound]

hey yall can someone explain to me

is the documentation for Mathf.Repeat wrong?

it says "loops value t so it's never larger than length and never smaller than zero"

but if you do mathf.repeat (3,3) it returns zero

3 is not larger than 3

[gloomy heart]

They won't be publish wrong documentation

[rough granite]

Smaller than 0 and equal to 0 are two different things

[plain hound]

yeah but it says never larger

not never larger or equal

set occurred

[rough granite]

If you read the example they give in the doc they explain if the value is the same as the length it'll be zero

"In the example below, the value of time is restricted between 0.0 and just under 3.0. When the value of time is 3, the x position will go back to 0, and go back to 3 as time increases, in a continuous loop"

Example

using UnityEngine;

public class Example : MonoBehaviour
{
    void Update()
    {
        // Set the x position to loop between 0 and 3
        transform.position = new Vector3(Mathf.Repeat(Time.time, 3), transform.position.y, transform.position.z);
    }
}

[plain hound]

you're right

it might be that the documentation is correct

and it's just the embedded comment on the function is wrong

i didnt think of that

anyway now i know the behaviour is not as described there, ty

[cosmic dagger]

What part of that comment (embedded description) is wrong?

[rough granite]

From the looks of the examples it give it looks like all it does is get the remainder of a time and devider no? What is the point of this function if this is the case

[plain hound]

if it loops the value t so it's never larger then length, implied is that when t is not larger than length nothing need occur

[rough granite]

Which in code is the same as doing float Remainder = t % length;

[plain hound]

however it actually loops when t is equal to length

as well

[rough granite]

This function is just a beautified modulo, why

Most useless Mathf function ive seen yet

[cosmic dagger]

it loops when t is equal to length. this stops t from being larger than length. when it's smaller, there is no reason to loop . . .

☝️ are you saying it doesn't do this?

[plain hound]

im saying that i checked the description of the function to determine what my len value should be

and i got it wrong because the behaviour of looping when t is equal to length is not mentioned

thats all

the comment omits this

it says larger

instead of "larger or equal"

which is different

thats all

i just came in to check if anyone else has encountered this

[cosmic dagger]

oh, i gotchu. you expected t to remain at the value of length instead of starting back at 0 . . .

[plain hound]

ya

[cosmic dagger]

as @rough granite mentioned, it's a modulo operation. when t is equal to length, the remainder is 0, therefore it resets. also, i believe that 0 is inclusive, and the length is exclusive, so it never actually reaches length, but resets when it's close enough . . .

[torn wraith]

I didn’t realize this would be 2inchs (50mm) when i had ordered it

It’s roughly 2600pages

[wicked cairn]

Looks like a nice book. You could probably learn most of that within an hour though with a video. General coding in unity is easier than basic NET. However if reading is your hobby, I’m sure it would be educational

[torn wraith]

I’ve watched many videos and I can’t seem to truly understand

[astral void]

Hey y'all, I'm trying to code in a script where I can put in a bunch of data. The plan is to have one script with access to lists of a large number of things in the game, and then the rest of the game can access it. I use this script to place everything inside of it. here is what I've got:

using System.Collections.Generic;
using UnityEngine;

public class ContentDrawer
{
    //contains all of the games data that isn't part of the core functionality. Here to be added to.
    public static List<StickerData> StickerList;
    public static List<GameObject> CharacterList;
    public static List<StatusData> StatusList;
}

I made this version. Ideally I would use scriptable objects to add new objects in the editor and then drag them in. However, I don't think this implementation does that, as per the Not Letting Me Do That. So how would I do it instead to let me assign things from editor into a script that holds all the data?

I have two other ideas since now I'm thinking this approach might just be... not good. One is to instead to define all of the data within the script instead of in the editor, in code. Issue with that is that there are some things I don't know how to get in the code... Like Images. Each StickerData contains an Image and I don't know how to code that in without "getting" it from a folder, and I don't know how to do that either... it also feels like a fragile system. Plus I don't think I'm high enough level in programming to really do that, since folders are different on different devices and such...
Other idea is similar, ignore this "content drawer" and pull the scriptable objects from the folders themselves, which I also don't know how to do.
Third idea is to make it not static and place the script in the scene but that just feels so messy and like there's better practice.
any advice appreciated :3

[wicked cairn]

Well, book it is lol. Coding isn’t for everyone.

[torn wraith]

I might just be expecting too much of myself as I haven’t had enough experience to be at where I expect to be, if that makes sense

[wicked cairn]

You are actually very close. What you should learn is what “DoNotDestroy” means. This will allow that single script to persist through all of your scenes and other scripts in those scenes can find that object

[spiral summit]

they say i need to destroy and initialize but i don't understand what i need to do

[wicked cairn]

The code you highlighted, use CTRl+X to cut it, then you can use CTRL+V to paste it. It needs to be inside of the { } brackets for example

{
Destroy()
}

[spiral summit]

awesome, now i know how to use Ctrl + X to cut

[sour fulcrum]

Generally i've used scriptableobjects to hold all of that stuff, then 1 scriptableobject to hold all the holders and a single monobehaviour singleton that contains a reference to that, a rough example being

public class ScriptableManifest<T> : ScriptableObject
{
  [field: SerializeField] public List<T> Content {get; private set; } = new List<T>();
}

public class ScriptableManifestManifest : ScriptableObject
{
  [field: SerializeField] public ScriptableManifest<StickerData> Stickers {get; private set;}
  [field: SerializeField] public ScriptableManifest<StatusData> Statuses {get; private set;}
}

public class GameManager : MonoBehaviour
{
  //Typical singleton stuff you can find online

  [SerializeField] private ScriptableManifestManifest mainManifest;
  public static ScriptableManifestManifest Manifest => Instance.mainManifest;
}

[astral void]

what does public class ScriptableManifest<T> mean? I see <T> but I've never actually understood what it is...

[sour fulcrum]

So you don't have to dive too deep into them to get this going but that syntax (the <letter>) is called a Generic

The general idea is you can use generics to construct code where you don't actually have to know and care about the type that code will be referencing

almosttt like a kinda placeholder

[astral void]

Idk what generic means 😔

but mostly what I'm seeing here is... it's the same as the idea I said I didn't wanna do?

My old version had the script as a monobehaviour on an object in scene with all the scriptable objects in lists, ofc with it being a singleton

[sour fulcrum]

The difference between that and this is that while yes the initial reference is tied to the scene (the ScriptableManifestManifest in the gamemanager) the rest of the references are owned by the scriptableobjects outside of the scene

in theory you could load that manifestmanifest via resources.load if you really don't want anything in the scene

[astral void]

hmmm ic

would it be viable to try to create the lists directly in the script and get images from folders somehow? or is that too complicated? I just feel like surely I can do that

[sour fulcrum]

and if you want that original snippet for convience, you could manually setup up kinda "forwarders" by doing

public static class Content
{
    //contains all of the games data that isn't part of the core functionality. Here to be added to.
    public static List<StickerData> Stickers => GameManager.Manifest.Stickers.Content;
    public static List<GameObject> CharacterList => GameManager.Manifest.Characters.Content;
    public static List<StatusData> StatusList => GameManager.Manifest.Statuses.Content;
}

[sour fulcrum]

That is something you could do, but honestly some form of what i'm recommending would be strongly preferred imo

[astral void]

hmmm ic lemme try smn

[polar dust]

You know how youd write List<float>();? The type there is generic, it's List<T>();

[sour fulcrum]

i don't know if this visualization helps understand generics much but for example here the T is kinda placeholder value for whatever you actually use when referencing and/or defining the ScriptableManifest<> class

[astral void]

so here, defining Stickers in ScriptableManifestManifest is passing in StickerData to ScriptableManifest?

the most confusing part to me is why we're using ScriptableManifest at all

I thought surely we could just do List<StickerData> and List<StatusData> directly because it seems the same to me?

[astral void]

oh wait I kind of get why you do this now, I like it
other questions still apply :p

[sour fulcrum]

1. The Type yes.

2. You could absolutely do direct lists in the ManifestManifest and functionally in this context it would be the same result, yes.

The reason I do it and the reason I recommend to do it is to further separate each type of "Content" into it's own thing with it's own responsibility.

eg. should this one big scriptableobject be in charge of the list of every type of content? or should each type of content have it's own kinda "leader" which talks to the big scriptableobject

[astral void]

oh wait I think I know what you mean?

I would create a scriptable object for each list

and populate those lists

and then the manifestmanifest has each of those lists separately

okok got it

I think this should work!

thanks a lot!

[sour fulcrum]

No worries, let me know if you have any questions 😄

[astral void]

ofc :3

oh I do have a question

what is a manifest? I seem to be poor at googling ._.

[torn wraith]

It might also be my instructor’s poor communication skills

[sour fulcrum]

Just a applicable word I tend to use

it's not a c#/unity specific term or anything

[astral void]

ohhhhhh ic

I thought it was I was so confused

ManifestManifest 😭

[sour fulcrum]

Very fair

[sour fulcrum]

programming be like that 😭

[astral void]

keep getting this error when trying to create a ContentDrawer scriptable object. Here's my code:

using System.Collections.Generic;
using UnityEngine;

[CreateAssetMenu(fileName = "DataDrawer", menuName = "ScriptableObjects/DataDrawer")]
public class DataDrawer<T> : ScriptableObject
{
    [field: SerializeField] public List<T> Content {get; private set; } = new List<T>();
}

this just doesn't work. In comparison, this does:

using System.Collections.Generic;
using UnityEngine;

[CreateAssetMenu(fileName = "DataDrawerDrawer", menuName = "ScriptableObjects/DataDrawerDrawer")]
public class DataDrawerDrawer : ScriptableObject
{
    //contains all of the games data that isn't part of the core functionality. Here to be added to.
    [field: SerializeField] public DataDrawer<StickerData> Stickers {get; private set;}
    [field: SerializeField] public DataDrawer<StickerData> Characters {get; private set;}
    [field: SerializeField] public DataDrawer<StickerData> Statuses {get; private set;}
}

no issue here. not sure why. Not sure what's different... I might be misunderstanding the purpose of this SO. but now I'm confused how I'm supposed to populate the list otherwise...

[sour fulcrum]

I'm sorry I forgot one small thing with this that you only have to do because Unity is silly

so c# wise this is all good but on unity's end for the data drawers you need to make a script per type of drawer you want to use to "define" the generic that's going to be used, eg.

StickerDrawer.cs

[CreateAssetMenu(fileName = "StickerDrawer", menuName = "ScriptableObjects/StickerDrawer")]
public class StickerDrawer : DataDrawer<StickerData> {}

CharacterDrawer.cs

[CreateAssetMenu(fileName = "CharacterDrawer", menuName = "ScriptableObjects/CharacterDrawer")]
public class CharacterDrawer : DataDrawer<CharacterData> {}

[astral void]

omggg boooo

"generic type" (doesn't work)

[sour fulcrum]

its cuz Unity wants a straight and direct answer on what that thing "is"

[astral void]

yeahhhhh
this is just less cool now 😔

ty anyway

[sour fulcrum]

its still worth it imo

[hard warren]

anyone know why I can't do

using System.IO;
.
.
.
var dbPath = Path.Combine(Application.persistentDataPath, _saveFileName);

and need to do this instead?

var dbPath = System.IO.Path.Combine(Application.persistentDataPath, _saveFileName);

[teal viper]

You mean the using directive? Because I don't see any other difference.

Using directives can only be specified at the global/namespace scope AFAIK. Definitely not in method bodies. At least in the namespace case.

[hard warren]

yes... i put the using directive at very top

[hard warren]

but it become like this, if i try

but this is okay

[teal viper]

Do you have a class named Path in your project?

[hard warren]

ah...

so that is why

ok thx. i understand now

[teal viper]

Yes. Compiler would prioritize types in your namespace/assembly.

[hard warren]

should i add name prefix to my class then?

[teal viper]

You can. You can also use explicit using in that file using Path = System.IO.Path

[hard warren]

ok thx ❤️

[astral void]

can I put these in the same file? I get this warning "No script asset for CharacterDrawer. Check that the definition is in a file of the same name and that it compiles properly." which I assume is because it's all in the same cs script. I can see why it doesn't like that but it isn't an error and I don't think the script reference matters anyway? alternatively if this is "bad practice" I'll change it to different scripts as well 😔

[sour fulcrum]

one file per

its silly

it may actually cause problems iirc

[astral void]

😢

[astral geyser]

u want make a menu in topline bar ?

[astral void]

dunno what that means

so probably not

[chrome wadi]

I'm pretty new to Unity... I gave my player a character controller. I implemented Jump. Now when I start my game, my capsule stays in place with the collider, everything is correct, but the velocity for the ground check just keeps falling. I did everything in the tutorial exactly as mentioned, but I'm just not getting anywhere.

using UnityEngine;

[RequireComponent(typeof(CharacterController))]
public class PlayerMotor : MonoBehaviour
{
    private CharacterController _controller;
    private Vector3 _velocity;

    [Header("Movement Settings")]
    public float walkSpeed = 5f;
    public float sprintSpeed = 8f;
    public float gravity = -9.81f;
    public float jumpHeight = 1.6f;

    [Header("State")]
    public bool isSprinting;

    private void Awake()
    {
        _controller = GetComponent<CharacterController>();
    }

    private void Update()
    {
        ApplyGravity();
    }

    public void Move(Vector3 input)
    {
        float speed = isSprinting ? sprintSpeed : walkSpeed;

        Vector3 move =
            transform.right * input.x +
            transform.forward * input.z;

        _controller.Move(move * speed * Time.deltaTime);
    }

    private void ApplyGravity()
    {
        if (_controller.isGrounded && _velocity.y < 0f)
        {
            _velocity.y = -2f;
        }

        _velocity.y += gravity * Time.deltaTime;
        _controller.Move(_velocity * Time.deltaTime);
    }

    public void Jump()
    {
        if (_controller.isGrounded)
        {
            _velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
    }
}



// from PlayerController.cs

    private void Update()
    {
        HandleMovement();
        HandleJump();
        _motor.ApplyGravity();
    }

[frail hawk]

do you want only gravity when you are grounded?

where did you find that code?

and you dont need 2 scripts for this.. you could handle all of it in the PlayerController instead of calling methods from another script.

[tame juniper]

hi! im making a upgrade tree ( or trying to ) and wondering how i can make loads of diffrent costs and texts without making tons of scripts, is that possible?

i can provide some scripts if need be

heres my button cost, thats the one im going to try tackle first as it seems the hardest

[astral void]

Scriptable objects is probably the way to go

You can then make a bunch of other objects to be used in the same script and just change the variables for each

[frail hawk]

i think you are not aware of oop. You can use serialized fields for that

[tame juniper]

ooh ok yeah ill try that

[frail hawk]

as Cozies also pointed out

[tame juniper]

thanks 👍

[frail hawk]

one small advice, use TextMeshPro instead Text for crispy looking Text

[tame juniper]

i like the style of it, once everything works im gonna add some pixel filters and such, but thanks for the advice!
