if raycast hits floor then true, if pressing jump key and raycast hits floor then jump

[polar acorn]

So, you probably want to change the variable you already have, rather than creating a new one with the same name

[livid arch]

ideally yes, i want the variable with the same name to be the same one

[polar acorn]

So, don't create a new one

[verbal dome]

bool jump = ... declares a new local variable
jump = ... modifies your existing jump variable

[polar acorn]

Just set the value of the one you already have

[livid arch]

ohh, it says it needs a refrence so i thought bool was that refrence to its type

[polar acorn]

Is this inside a static function

[frail hawk]

stop sending images of your code.

[livid arch]

 public bool jump = false;
    private float yRot; /// flipped cause dumb unity

    private UnityEngine.Vector2 playerMouseInput;
    public UnityEngine.Vector3 playerMoveInput;
 
public class Raycast : MonoBehaviour
    {
        Ray playerSpring;
        private readonly float springMaxDistance = 10;

        void Start()
        {
            Ray playerSpring = new(transform.position, transform.forward);
            CheckForColliders();
        }

        void CheckForColliders()
        {
            if  (Physics.Raycast(playerSpring, out RaycastHit hit, springMaxDistance))
            {
                jump = true;
            }
        }
    }

[verbal dome]

IMO it's fine when there's an error included

In small doses

[livid arch]

i cant put errors in a text thing

[polar acorn]

There's nothing named jump in this class

[livid arch]

theres a public bool at the top

[polar acorn]

No? There isn't

Nothing here

[livid arch]

    private float yRot; /// flipped cause dumb unity

    private UnityEngine.Vector2 playerMouseInput;
    public UnityEngine.Vector3 playerMoveInput;
    public class Raycast : MonoBehaviour
    {
        Ray playerSpring;
        private readonly float springMaxDistance = 10;

        void Start()
        {
            Ray playerSpring = new(transform.position, transform.forward);
            CheckForColliders();
        }

        void CheckForColliders()
        {
            if  (Physics.Raycast(playerSpring, out RaycastHit hit, springMaxDistance))
            {
                jump = true;
            }
        }
    }```

[polar acorn]

Why do you have a class inside of this class?

[livid arch]

hmm, i wonder why its indented weirdly like that

[livid arch]

its what a tutorial did

[polar acorn]

What tutorial?

[polar acorn]

Gimme the link

[frail hawk]

your declerations are outside of the class they have to be in the class scope

[livid arch]

https://youtu.be/B34iq4O5ZYI?si=J6B1LDFUDdjDaM_6&t=165

[frail hawk]

and i waould be carefull with the classname "Raycast"

[polar acorn]

Notice how this is not slammed haphazardly inside of another script

[livid arch]

): im sorry this is why im in code beginner

[polar acorn]

"I did it exactly like the tutorial so why does theirs work and mine doesn't" counter:
Number of times it wasn't exactly like the tutorial: 183
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2025-04-08

This is an example, showing you how to use a raycast and do something when it hits

you aren't supposed to windmill slam this entire block of code into an existing class

[livid arch]

IM SORRY

[frail hawk]

don´t be sorry, just learn the c# basics before diving into unity development

[livid arch]

the courses i found were like 4 hours long so i was hoping i could just jump into it

[polar acorn]

4 hours is pretty short

[silent valley]

I remember when i was sooo afraid of raycast. It looked scary but now it's the easiest thing ^^

[rich adder]

you dont have to do 4 hours in 1 shot.

[queen adder]

guys question i got bullet and it like collide with money on the ground how do i make it to be able to walk pass it and also when i walk into money i kinda stop for a sec before i collect it bc it collide i want it to detect when it collide but still like pass it

[polar acorn]

If you want to detect a collision but be physically stopped by it, use a trigger instead of a solid collider

[queen adder]

got tutorial for that maybe am new to unity?

[polar acorn]

You click a checkbox on the collider

[queen adder]

oh

[polar acorn]

https://docs.unity3d.com/6000.0/Documentation/Manual/collider-interactions-create-trigger.html

And use OnTrigger___ functions instead of OnCollision___ functions to detect interactions:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Collider.OnTriggerEnter.html

[queen adder]

thanks you it worked

[languid nova]

Hey 🙂 What's the best way to have a particle system on top of UI? there seem to be a few ways

[honest haven]

bump

[eager elm]

Maybe it is clearing everything, but also re-adding the first item. Basically detecting a controller input twice. Maybe add a Debug.Log() to the end of your CancelItem method to see if everything has been cleared.

Or select items in a different order (not the top left first) and see which item ends up in the first crafting slot after cancelling

[tawdry quest]

4 hours is not enough

that course will prolly only teach you the basics

[naive pawn]

well yes we were talking about the basics there

[tawdry quest]

yeah but thats not really enough to make a full game

thats what i meant by that

[livid arch]

Well c# tuorials are just core language and not unity stuff

[tawdry quest]

but you need to know it to write proper code for unity

[vague charm]

Hello I am trying to make a map but when I try to place the tiles they overlap instead of being individually spaced and placed.

Is there a way to change this? I am still very new so sorry if it sounds silly

[rich adder]

Unity's entire API is c# so yes the core language is 70% of your work

[rich adder]

is this a code question ?

[livid arch]

I feel like im learning still but i will still watch the basics vid

[vague charm]

Should I ask this in another place? Sorry

[rich adder]

your tiles are larger than your grid cell size

also #💻┃unity-talk or #🖼️┃2d-tools

probably check PPU and such

[west sonnet]

I'm making a 2D top down character controller but my player keeps moving after I've let go of the key. How can I get it to stop when I release the key?

In this example, I'm just tapping the movement keys

[vague charm]

Oh so if I change the grid size that would make them paste how I want? That just gave me like 3 more questions lol

I'll post in the other channel thank you 😭

[short hazel]

You accumulate the velocity with +=, so when you don't input anything you just add 0, which does not change the velocity, ie. it keeps its previous velocity

[west sonnet]

Ahhh I see

Can you give me an idea on how to fix it?

I was thinking I could code is to detect when a movement key is released, to set the velocity to 0?

[short hazel]

You could also increase linear drag on the Rigidbody so it slows down over time, if you need that

Requires no code changes

[west sonnet]

I'm using a Kinematic Rigidbody because it's a top down, so don't need gravity

Oh wait, I could just set gravity to zero 🤦🏻‍♂️

[wintry quarry]

gravity or no gravity is not what the kinematic setting is about

that's what gravity scale is for

[west sonnet]

Kinematic removes physics properties

[wintry quarry]

kinematic turns it into an unstoppable force unaffected by forces or collisions with other objects

[halcyon jacinth]

hey guys, i was planning on making a simple code that checks if the character is airborne it wont allow it to jump again, the code works fine but my only issue is that when the character touches the ground it dosent uncheck the checkbox in unity

[wintry quarry]

your code does nothing

[halcyon jacinth]

dang

[wintry quarry]

Airborne.Equals(false) doesn't do anything

if you want to set it to fralse you would do Airborne = false;

[halcyon jacinth]

ooohh

[west sonnet]

What's the difference between a Kinematic Rigidbody and an object with a collider and no Rigidbody?

[wintry quarry]

your code also doesn't make a lot of sense.

[halcyon jacinth]

yeah that's obvious i should've tried it😭 thanks

[wintry quarry]

An object with a collider has no mass, no momentum. no velocity

[wintry quarry]

Also setting airborne to false every time youi collide with any object seems logically wrong to me

what if you hit a wall or an enemy or something

[halcyon jacinth]

oh no i only made it so that it if it only touches the ground it dosen't jump

[wintry quarry]

Sure but then you have this else block which will run anyway

so you are always doing it

[rocky canyon]

am i high?

[wintry quarry]

any time you collide with anything

[west sonnet]

But can you do anything with those properties if a kinematic rigidbody can't interact with any other forces?

[wintry quarry]

yes

you can set the velocity

also

the rigidbody will actually interact with other dynamic bodies properly

a naked collider will not

[halcyon jacinth]

my god it seems like im the high one here😂

[west sonnet]

Ahhh I see, thanks

[rocky canyon]

hehe.. you'll come out the other side a more sensible person 🙂

[rocky canyon]

public class RigidbodyGroundCheck : MonoBehaviour
{
    public Transform groundCheckPoint;
    public float groundCheckRadius = 0.2f;
    public LayerMask groundLayer;

    Rigidbody rb;
    bool isGrounded;

    void Awake()
    {
        rb = GetComponent<Rigidbody>();
    }

    void FixedUpdate()
    {
        isGrounded = Physics.CheckSphere(groundCheckPoint.position, groundCheckRadius, groundLayer);

        if (isGrounded)
            Debug.Log($"Grounded at {groundCheckPoint.position}");
    }
}``` i'd use a different method.. theres OverlapSphere, CheckSpheres, Spherecasts, Raycasts, TriggerColliders, etc

for this example ^ it'd just be a simple gameobject u place near the feet of the character..
the checkRadius would be the width/size of the area.. and the groundLayer would be Layers you've assigned to be Ground/Floor etc

that way its not constantly checking everything u hit

[halcyon jacinth]

this wayyy too advanced for me i'm just a beginner but still thanks man😭

[rocky canyon]

void OnDrawGizmosSelected()
{
    Gizmos.color = Color.green;
    Gizmos.DrawWireSphere(groundCheckPoint.position, groundCheckRadius);
}``` use Gizmo's while u learn this stuff

really helps to visualize these things

[rocky canyon]

if you feel that way i totally understand..
just trying to get you thinking about other proper ways to do this..
yes it'd be a bit more complicated.. but its something your probably gonna end up needing to learn anyway

interaction / detections is a big part of game-dev

https://scriptbin.xyz/nebeyagugo.cs heres the same script w/ comments on every single line describing whats happening..

[halcyon jacinth]

thanks for the help man, much appreciated

[rocky canyon]

🍀

the more generic help i can give is don't neglect Debug.Log()

you can debug ur values, hints, tips, notes, etc.. all thru ur code.. they'll get displayed in the Console window

can really help understand the things ur workin on.. a big problem i see with beginners and even novice's alike is making assumptions... "i programmed it this way so i expect it to do this.." well.. it doesn't always do exactly what u expect.. lots of ppl get hung-up by assuming they know whats already going on

[west sonnet]

Can anyone help me figure out how to make the player rotate on the Z axis to follow the cursor?

This method is called in update

[rich adder]

transform.right = dir

[short hazel]

transform.right = dir; - assuming the "forward direction" points right locally

[rocky canyon]

u sure u want WorldToScreenPoint? or ScreenPoint to world?

[short hazel]

Works both sides, here everything is converted to screen space

[west sonnet]

I wasn't sure because I thought transform.right was for Horizontal movement?

[west sonnet]

Hmmmm not sure what the difference is

[rich adder]

transform.right is the local rotation
(which way is red arrow pointing)

[west sonnet]

Ah, I think I get it

[rocky canyon]

WorldToScreen point takes a world position and shows u the value that a Screen Object (like UI) would be placed

to be directly on top of it

the other is opposite..

u working in 2d or 3d?

i typically use raycasts and raycast from my camera thru the screen position of my mouse (this will hit a position in the world)

w/ that position cached i can just have my world character rotate to look at that world position

[west sonnet]

Ahhh right, the way I've set up my game, the Z axis (Blue arrow) is what determines rotation, so I'm guessing I just have to rotate everything?

[rich adder]

are you doing 2D ?

[west sonnet]

No, that didn't work

[rocky canyon]

heres an example of using a screen position to convert it into a world position

[west sonnet]

Forgot to send pic

[rocky canyon]

ahh 2d it is

well.. psuedo 2d

[rich adder]

this doesnt help much.. I guess 2d?

[west sonnet]

Oooooh that's cool! did you make that?

[west sonnet]

Yeah

[rocky canyon]

ya

[rich adder]

is camera in orthographic mode?

[west sonnet]

Yup

[rich adder]

which way is rotating now

[west sonnet]

I'm just showing it in 3D in the screenshot to show that my rotation is on the Z axis

so transform.right won't work, I think?

[rich adder]

rotate the object on the Z with the inspector and look what happens to the Red arrow

typically that is your "forward" in 2D

[rocky canyon]

soo something like this?

[rich adder]

sometimes the Green UP

[west sonnet]

I've just realized that my world rotation and object rotation don't match. Is that normal?

The axis'

[rocky canyon]

using UnityEngine;

public class RotateTowardsMouse2D : MonoBehaviour
{
    void Update()
    {
        Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        mousePosition.z = transform.position.z;
        Vector3 direction = mousePosition - transform.position;

        transform.up = direction.normalized;
    }
}
``` 🆓

[west sonnet]

Yes, exactly

[rich adder]

rotation axes are different

[rocky canyon]

just change out the transform.up for forward or right

or w/e u need

@rich adder he had 85% of it

i'll give the dog a bone lol

and also.. boom

Screen -> world. not the other way around lol

[west sonnet]

Transform.up worked, but why? Doesn't up affect the Y axis?

[verbal dome]

You can use either one, screentoworld on the mouse pos, or worldtoscreen on the transform position. As long as they are in the same space (and plane)

[west sonnet]

and I've just realized I've made a big mistake

My player now moves in relation to the cursor and not world space. So if I press up, it goes towards the cursor rather than up the screen

[rich adder]

thats where you use Vector2 rather than transform

eg
Vector2.up * moveY * speed instead of transform.up * moveY * speed

World coordinates vs Local (according to its rotation)

[west sonnet]

Like this?

[rich adder]

yes but you can comebine it to 1 call

also do you plan on keep increasing speed ?

otherwise you assign it = instead of increment +=

[west sonnet]

Just so I understand it correctly, as you said, you use Vector2 to move the object in world space, as opposed to local space, which transform would do

[rich adder]

transform gives its local rotation so if you use it in your calculation it points to whatever thats facing

[west sonnet]

Ah right yeah, that'll just keep increasing forever

[rich adder]

You can test for example Debug.Log(transform.up) then rotate the object and watch it change.. Vector2.up is more of a constant true to the same direction (eg Its always "North" in a sense)

[west sonnet]

when I change it to = , I can no longer move left and right

[rich adder]

did you combine it into 1 call?

otherwise you're overriding the previous action

[west sonnet]

Ah no, I'll try that

[rich adder]

Vector2.up * moveY * speed + Vector2.right * moveX * speed

[west sonnet]

I don't understand why transform.up worked to rotate my player, if my player is rotating on the Z axis?

Transform.up rotates on the Y Axis, right?

[rich adder]

transform.right / transform.up both rotate on Z

dir = (targetPos - transform.position)
transform.up = dir
transform.right = dir
Will do same thing

[rich adder]

yeah notice how it says When is rotated the Y also changes

[polar acorn]

When rotating, the axis of rotation is the one you're rotating about. Imagine a pole sticking through the object at that axis, and then gripping and spinning the pole

If you want an object to turn left and right, you'd jam a vertical pole through it and twirl that pole

[west sonnet]

So in my image above, wouldn't that be the Z axis? (Blue arrow)

[slender nymph]

transform.up is just the direction that the object's own Y axis points, if you rotate around transform.up then you rotate around the Y axis, however if you assign transform.up which is what you seem to be doing for 2d objects then it would rotate around the Z axis because you are just changing the direction that transform.up points in

[polar acorn]

Enable the position gizmo, and make sure it's set to local

Ah, right, setting transform.up. I came into this late, I thought this was the usual "Why rotate about Y when I want the object's X to move?" question

[rich adder]

ya same.
but also OP is confused I think the colors change on rotation mode Z/blue is Left/Right rotation (view from 2D)

[west sonnet]

Oooh okay, I'm changing transform.up to dir

[rich adder]

so basically transform.up isn't what ur rotating around, you're simply Pointing it / assigning with a specific direction. Its still rotating around the Z axis (blue)

[west sonnet]

Right

RIGHT

Transform.up is where my player is facing, not what it's rotating around

Thank you everyone

[obtuse ether]

trying to program a brick breaker thing and trying to make it destroy all the bricks from the previous game

I checked and the list of gameobjects is getting filled up

i just dont know how to make my code destroy each brick

nvm i got it working

[rich adder]

basically i is the index of each item in the list

[wintry quarry]

you could also just do foreach (var brick in Bricks) Destroy(brick);

[polar acorn]

Bad day to be Bricks[0]

[wintry quarry]

but yeah Bricks[0] is just the first one

[polar acorn]

Getting destroyed over and over again

[covert flower]

I have a really frustrating issue where the grounded boolean isnt updating when it should could someone assist

[polar acorn]

What is whatIsGround set to?

[rich adder]

also check Physics.Debugger for Casts and see where your cast is

[wintry quarry]

Also is playerHeight *.5 + 0.2 far enough to reach teh ground?

[covert flower]

its the layer of the floor

[wintry quarry]

also instead of doing body.transform.position you can just do rb.position directly

no need for an extra variable and all that stuff

[covert flower]

it manages to turn grounded on when it spawns but never disables it

[wintry quarry]

then your raycast is always hitting something

probably your layermask is wrong or the layers on your objects are wrong, or you referenced the wrong object as body

[covert flower]

yeah mb i changed it to try fix it and never changed it back lol

[obtuse ether]

oh ive never used foreach b4 lol

anyways it works by switching from just destroying the first one to Destroy(Bricks[i]);

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/iteration-statements

[wintry quarry]

yep, basically the same thing

[covert flower]

omfg the player height was too small. sometimes its small mistakes that cause the most stress lmao

[obtuse ether]

now the list just has a bunch of missing gameobjects and the list keeps getting longer and idk if theres anything i can use to just remove them

[polar acorn]

Well, you've destroyed the objects, that's why they're missing.

[obtuse ether]

yeah is there any way for me to just delete them from the list after destroying the objects

[polar acorn]

Is it a list or an array

[obtuse ether]

i think its an array im just saying list bc idk

yeah its an array

[polar acorn]

Then no. Arrays are a fixed size upon creation and will hold exactly that many elements at all times

[obtuse ether]

oh alright

is there anything bad abt me using an array for this or is it fine its just a little janky

[polar acorn]

You would use an array when the number of things in the collection does not change

You would use a list when it does

[obtuse ether]

oh alright

ill figure out how to use a list instead

[rocky canyon]

^ .Add .Remove

[obtuse ether]

alr im switching from an array to a list

and how do i add a bunch of gameobjects at a time

it doesnt exactly like me just using = GameObject.FindGameObjectsWithTag("Brick");

and .add only adds them one at a time iirc

[rich adder]

.ToList

[polar acorn]

AddRange or ToList

[livid arch]

so dont combine classes?

[polar acorn]

Not unless you have a very good reason to and know why you're doing so

[honest haven]

so if i have a script thats on the parent of a button and on that script i have a function that calls a coroutine. but that coroutine is inside a method that is called onclick of a button but i set that button active state as false at the begining would that stop the return of the coroutine from completing even if the parent object holds the script thats not being deactivated. Got a issue where my corouine doesnt come back

[polar acorn]

Holy run-on sentence batman! Give me a second to make sense of this sentence

[honest haven]

haha sorry

I have a script attached to the parent of a button. In this script, there's a function that calls a coroutine. This coroutine is invoked when the button is clicked (onClick). However, at the beginning of the process, I set the button’s active state to false.

My concern is whether deactivating the button will prevent the coroutine from completing, even though the parent object (which holds the script) remains active and not deactivated.

[polar acorn]

I think what you're asking is "Does disabling a component that's running a coroutine stop the coroutine" and I believe it's fine as long as the object running the coroutine is still active

[slender nymph]

if the button object is the one that started the coroutine then the coroutine will be stopped when that object is disabled. if this parent object is what actually started the coroutine then it won't be stopped when the button is disabled

[honest haven]

yh so i can a onclick called CancelItem and when i press that i hide that button that has that call it does all the logic untill the coroutine it stops after the yeild return

perfect thanks. so i have a issue when i click on this button with mouse no issues when i click on it with controller it registers over 8 times and courses lots of bugs. So i am adding a flag but struggling to reset it becuase im hiding the button https://paste.mod.gg/wzgmugxzomsz/0

any ideas

yield return StartCoroutine(ResetCancelCooldown()); if i add this to a random function and just wait for that to return would that work

https://paste.mod.gg/pqfqdjmidnln/0 would this work as a good work around

[slender nymph]

you cannot yield in a method that returns void so obviously the second would not work

[honest haven]

yh i just did it quickly

[slender nymph]

you also don't really need to yield that coroutine unless you are yielding the first

[honest haven]

was just an example

like this

[slender nymph]

that is effectively the same thing as just starting the coroutine without yielding it at the end of the first coroutine

[honest haven]

yh i was hoping that it would just still wait for the return as its not in the same function but yes you are 100% correc

coroutines get me every time

[slender nymph]

are you yielding the start of the first coroutine at all? if not, then it is pointless to yield at the end of the coroutine because it will just wait to do nothing

[honest haven]

i am not. I just need away to wait a few secs i guess i can just do it with out a coroutine. just not sure why a onclick would register more then once when a getbuttondown only registers once.

is there a better way to handle more then one click

i could set a flag at the very begining i guess

[slender nymph]

i'm not saying that ResetCancelCooldown doesn't need to be a coroutine, i'm just saying you don't need to yield the start of that coroutine

if the last line of a coroutine is a yield then the yield is likely pointless as it will yield to do nothing after yielding

[honest haven]

yh i see what you mean

[naive pawn]

this isn't a code issue, see #💻┃unity-talk (or if you think it's related to urp, then #archived-urp, i guess?)

[azure yarrow]

ok will do

[queen adder]

anyone know why when i run the code and test it the scale change like permenant even after i stop the game the circle size change

it changes to this after i stop test

[polar acorn]

You appear to be changing the scale of the prefab asset

[queen adder]

how could i change it size after i spawn it

or atleast spawn it bigger

[polar acorn]

Instantiate returns a reference to the thing it spawned. Change the size of that

[queen adder]

will that work to?

and ijust change the g2 size

go = gameobkect

[polar acorn]

That literally doesn't do anything

it just makes another variable that also references the prefab

go is the prefab. Setting something to go is setting it to the prefab.

[queen adder]

no but like i create new gameobject that gameobject = to the prefab and i hange the gameobject size that way i dont change the prefab

[polar acorn]

Instantiate creates a new object, which it returns as a value

and you can store that in a variable

[polar acorn]

If you set go2 to the prefab, changing the scale of go2 will change the prefab because go2 is also the prefab

[queen adder]

yeah but if i spawn the bullet and save it then change the scale i pretty sure you will be able to see the bullet small for a frame or 2

[polar acorn]

Are you going to wait a frame or 2 to change the scale?

Why not just do it right away

[queen adder]

so if i change it immidle it wont be able to show it for a frame ?

[polar acorn]

A frame is how long it takes for every object's Update to finish. Everything done inside of a single update loop, by definition occurs within the same frame

[queen adder]

oh

okay thanks sry if am a bit dumb

@polar acorn how do i do what you said

[polar acorn]

Instantiate returns a reference to the object it creates.

Change the scale of that

[queen adder]

yeah but how do i save the refrensce

i tried this

i figured it out tahnks for the help digiholic

[green jackal]

I'm trying to make a basic spawner for randomly placing cubes around a scene, but with the game object for the spawner there's no field in the script to attach any prefabs to

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

public class Spawner : MonoBehaviour
{

    public GameObject myCube;


    public void SpawnCube()
    {
        int spawnPointX = Random.Range(-10, 10);
        int spawnPointY = Random.Range(10, 20);
        int spawnPointZ = Random.Range(-10, 10);

        Vector3 spawnPosition = new Vector3(spawnPointX, spawnPointY, spawnPointZ);

        Instantiate(myCube, spawnPosition, Quaternion.identity);
    }

}

[polar acorn]

Do you have any compile errors

[green jackal]

No errors

[polar acorn]

Can you show a screenshot of your console? Including the settings bar at the top?

[polar acorn]

Compilation might be stuck, try restarting unity

[green jackal]

Restart didn't fix it, but I'm noticing in my assets field when I click on the script it doesn't show to have the code I put in, it just has the void start and update lines

Then you're looking at a different file, or you haven't saved

[teal viper]

Probably an ide glitch.

Take a screenshot of your ide window with the script

[green jackal]

Sorry I'm not quite familiar with terminology yet, hopefully this is what you mean

[teal viper]

Yeah. It looks fine. Copy your code and restart the ide(visual studio)

[green jackal]

Another thing, I've been opening my script with the open C# project button, but when I double click on the script itself in unity it doesn't have the code, says solution1 instead of my project name, and is labeled as a miscellaneous file

[polar acorn]

Lending credence to my "These are different files" theory

If opening a file in Unity doesn't show Assembly-CSharp as the solution, you need to configure your !ide

[eternal falcon]

💡 IDE Configuration

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

Select one:

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

[green jackal]

Threw the code into the miscellaneous file version and it works fine

[teal viper]

Definitely a config issue

Possibly having several versions of vs installed

how can i reference a singleton on an object that is inactive when i start my game?

[wintry quarry]

The same way you always reference a singleton

Usually using its static reference variable

Unless you mean it's the singleton itself that is inactive?

Which would be quite unusual

[keen owl]

How are you calling SpawnCube(), just out of curiosity?

[sturdy wharf]

hey i found this cool tileset online, does anyone know if its possible/if there is a good tutorials online where i can make procedural generation using a tilemap like this?

https://craftpix.net/freebies/free-undead-tileset-top-down-pixel-art/

[tired summit]

you can use auto tile + state collapse function, cell state sim(like conway game of life), perlin noise or organic noise alike do to it

[polar acorn]

High Lord Wolnir, is that you?

when i move the mouse, the object used to indicate the position of the mouse is jittering. ive put the camera movement stuff in LateUpdate but im still getting the issue so im not sure why its happening
if anyone could point me in the right direction id appreciate it 🤞

[naive pawn]

unrelated to the issue, but why do you have visual scripting and serialization in CameraMovement? 🤨

[oblique torrent]

ahaha mustve happened by accident

ill clean it all up later 😅

[keen dew]

Might not fix it but multiplying rotateDelta by deltaTime is wrong

[oblique torrent]

wait how come?

[naive pawn]

https://unity.huh.how/mouse-input-and-deltatime

[keen dew]

Mouse movement is already distance per frame

[oblique torrent]

Anything that returns a fixed value when evaluated should be scaled by deltaTime. For example, joysticks, held key presses (like WSAD movement), and constants.
If the returned value is dependent on the length of a frame, or isn't constantly evaluated, then no scaling should be applied. For example, mouse delta, scroll-wheel delta, and button presses.

oooh

that makes sense

ill fix that thanks

it didnt fix the actual issue but thats good to know 🙏

[keen dew]

It would help to see a video of the jittering

[oblique torrent]

let me try get one

[keen dew]

You can also log what object the raycast hits in the inputmanager and the value of lastPos

[oblique torrent]

oh

i didnt realise it recorded my audio

[keen dew]

right so the marker lags one frame behind

[oblique torrent]

yehh

one frame behind the camera rotation 🤔

but the camera rotation is already in late update

sooo im a bit lost since thats the only fix i knew

[keen dew]

That's the wrong way around, the camera moves after setting the marker

put the camera movement in Update and marker placement in LateUpdate

[oblique torrent]

alright ill give that a try 👌

it fixed the issue thank you

um do you know why it was jittering when they were both in Update

is that just something out of my control

[keen dew]

Updates run in arbitrary order, it just happened to be in the wrong order

[oblique torrent]

ah ok makes sense

[delicate portal]

Hey! Upon changing scenes, I'm unsubscribing from events, but when I come back to the scene and resubscribing, they don't work.

[hexed terrace]

does the gameobject with that component on persist through scene changes ?

[delicate portal]

Which component specifically? There is a MainMenu component which doesn't, but there is a GameManager which does

[hexed terrace]

The one in the screenshot..

[delicate portal]

Thats from the MainMenu's script

[hexed terrace]

Start() only runs once per instance

[delicate portal]

It does run on scene changes

[ivory bobcat]

Place a log and see if start fires

[grand snow]

probably a new instance then

[delicate portal]

It does

[grand snow]

it executes one time per instance

[delicate portal]

So where should I put the subscribes?

[ivory bobcat]

The second time when it should subscribe but doesn't

[grand snow]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/SceneManagement.SceneManager-sceneLoaded.html

[ivory bobcat]

How are you referencing these objects? If any of these objects persist between scenes, you'll be referring to different objects if they target those within their scene specifically (drag/drop method ect)

[delicate portal]

Singleton if you're asking that

[ivory bobcat]

But you haven't answered the question yet

[delicate portal]

Referencing objects which contain the events the GameManager for instance subscribes to is found by a simple FindObjectOfType

[ivory bobcat]

Elsewise you'd have something likecs Manager.Instance.ArcadeMenu.SetActive(false);etc

[delicate portal]

Those gameObjects are referenced by drag/drop method yes

[ivory bobcat]

Do any of those objects persist between scene?

[delicate portal]

No.

[hexed terrace]

Do a recording of the setup and the issue

[ivory bobcat]

If none of these objects persist between scenes, it likely isn't an issue with the subscription of events as every new load of the scene would do the same thing but rather what you're wanting to do.. (the communication between the Singleton and this/these objects)

Where your Singleton likely isn't targeting these objects that you you've subscribed to - whatever it is that isn't happening but should (have not been described yet)

[delicate portal]

This is the basic setup without me unsubscribing, just the plain issue.

You see the backbutton worked the first time, but after unloading and loaded that scene, it didnt

[grand snow]

attached a debugger to check what the button does?

can only presume you unsub at the wrong time

[hexed terrace]

by setup - wanted to see the objects in the hierarchy and the relevant inspectors

[delicate portal]

I'm not unsubbing now.

[grand snow]

👏 debugger now 👏

[delicate portal]

Nothing is I would say relevant in the inspector.

[delicate portal]

Well there is one in the video, where do you say more?

[grand snow]

you have not shown enough and a video is not enough.
Use a debugger to check what is really happening when the button is pressed but nothing happens visually

[delicate portal]

Yeah there is a debug in the console saying "Button pressed"

[grand snow]

e.g. where your button click invokes the other event

[delicate portal]

I see.

[grand snow]

a debugger lets you actually see what is happening with great detail, a random log stating the obvious doesnt help you

[delicate portal]

So basically it just doesn't register it the second time

But where should I try to insert the unsubscribe logic?

[grand snow]

but why? (is the event now null meaning you did unsub? is it calling the event but there is some logic error with the subscriber?) DEBUG IT

[delicate portal]

Sure, thats why I'm asking where would I unsub

To advance a bit further and I can debug the problems regarding that

[grand snow]

when the subscribing mono is destroyed probably

as remember when the mono is "destroyed" it remain subbed and will still try to do stuff

[cosmic dagger]

It looks like the objects setup with the button are no longer referenced when the scene is reloaded. Check the references associated with the button to ensure they are still setup after the scene is reloaded . . .

[delicate portal]

It looks to me they are

I unsub on the OnDestroy method and resub on the OnEnable method this way:

The same issue persists.

[hexed terrace]

what does the log in OnEnable print?

[delicate portal]

False, everytime

[hexed terrace]

so .OnBackButton is your own event in arcadeMenuUI - go check that next

[summer sluice]

excuse me, i want to ask because i'm new to using unity. here i use a template from the unity fps game tutorial, what i'm confused about is where can i find the weapon script or how can the weapon give damage to the hoverbot enemy.. i want to know how the script is and apply the weapon script that can give damage to the enemy that i made myself.

[hexed terrace]

surely if you follow the tutorial it will explain this to you

[summer sluice]

i cannot find the right tutorial that explaining the method

[hexed terrace]

here i use a template from the unity fps game tutorial

err... this

[summer sluice]

In the tutorial I got it was only about how to add prefab asset objects (drag and drop), and publish the game.🥲

[hexed terrace]

You'll need to look through the scripts, they'll be named appropriately.
Open the demo scene, look at how things are setup there.

No one here will know any of that - "the unity fps game tutorial" doesn't really mean much on its own, and it's unlikely anyone is going to take the time to go through it to find out for you.

[summer sluice]

If I add a new weapon script, will there be any problems that occurs because of that?

or if i add a new script, it should add a new weapon too?

this is my walljump code, for some reason, the force is added before exiting wallrun is set to true.. how can i fix this issue?
https://scriptbin.xyz/nufilenuyu.rust

[naive pawn]

the force is added before exiting wallrun is set to true
that's simply not what's happening in this code
how are you coming to that conclusion?

[hexed terrace]

that doesn't prove anything as we don't know where the 'exited wallruntrue' is being called

also, as they're all at the same time.. it's difficult to see exactly when it's all happening. I don't use the default console, does it not show the frame when the log was printed?

[digital kayak]

what do you use for that then

[hexed terrace]

I use 'Editor Console Pro'

[digital kayak]

ok

is it like a package you have to install

i dont think so 😔 but we can assume its printed in order of frames right?

it is, but is it same frame

[hidden marten]

oh

[hidden marten]

can you check this out please?

[naive pawn]

ok... what's off about this?

[hexed terrace]

the force isn't added before the bool is set true, you just don't log it out until after everything.

Update logs out exited wallrun false
you set it to true
you do the jump
you log wall jumped
you now exit the wallrunning

you log out exited wallrun true in update on next frame

update won't interrupt anything to re-log something after it changes value

[hidden marten]

oohh i get it

then something else is going on... my main issue is that force isnt added in the normal when i walljump..

I've got a drag & drop script for my inventory right now. But when I attempt to drag the item slot of my item, it drags the entire scrollview instead.

I've disabled all raycast targets of UI stuff that shouldn't drag. And only the handle has a raycast target. Handle is 30 pixels wide only.

Anyone know what the issue could be?

This is the script:

using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class ItemDragHandler : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler
{
    private Transform originalParent;
    private Canvas parentCanvas;
    private CanvasGroup canvasGroup;
    private ScrollRect scrollRect;

    private void Awake()
    {
        canvasGroup = GetComponent<CanvasGroup>();
        parentCanvas = GetComponentInParent<Canvas>();
    }

 public void OnBeginDrag(PointerEventData eventData)
    {
        scrollRect = GetComponentInParent<ScrollRect>();
        if (scrollRect != null)
        {
            scrollRect.enabled = false;
        }
        // Record the original parent so we can return to it if needed.
        originalParent = transform.parent;
        // Reparent to the Canvas so the dragged item remains visible over other UI.
        // Find your drag layer in the scene (cache it if possible)
        GameObject dragLayer = GameObject.Find("DragLayer");
        if (dragLayer != null)
            transform.SetParent(dragLayer.transform, true);
        else
            transform.SetParent(parentCanvas.transform, true);
        transform.SetAsLastSibling(); // Ensure it's on top
        // Disable raycast blocking so that drop targets can detect the drag.
        canvasGroup.blocksRaycasts = false;
    }

    public void OnDrag(PointerEventData eventData)
    {
        // Update the dragged object's position to follow the pointer.
        transform.position = eventData.position;
    }

    public void OnEndDrag(PointerEventData eventData)
    {
        // Re-enable raycasts.
        canvasGroup.blocksRaycasts = true;

        // Re-enable the ScrollRect if it was disabled.
        if (scrollRect != null)
        {
            scrollRect.enabled = true;
            scrollRect = null; // Clean up.
        }
        // If no valid drop target was found (i.e. parent is still the canvas), snap back.
        if (transform.parent == parentCanvas.transform)
        {
            transform.SetParent(originalParent, true);
            transform.localPosition = Vector3.zero;
        }
    }
}

I want that, when you choose a specific character and then you click start, add a script to the prefab that comes with the character you choosed

    {
        if (TokenDETECT.hasSelected == true)
        {
            if (other.transform.CompareTag("TokenP1"))
            {
                p1char = true;
                PlayerStorage.P1Prefab = prefab;
                PlayerStorage.P1PauseArt = pauseArtPrefab;
                PlayerStorage.P1Pivot = artPivot;
                mustAddMove = true;
                AddMove();
            }

            if (other.transform.CompareTag("TokenP2"))
            {
                p2char = true;
                PlayerStorage.P2Prefab = prefab;
                PlayerStorage.P2PauseArt = pauseArtPrefab;
                PlayerStorage.P2Pivot = artPivot;
                mustAddMove = true;
                AddMove();
            }
        }
    }```

    {
        if (mustAddMove == true)
        {
            if (p1char == true)
            {
                prefab.AddComponent<P1move>();
            }

            if (p2char == true)
            {
                prefab.AddComponent<P2move>();
            }
        }
        
        StopThaShi();
    }

    void StopThaShi()
    {
        mustAddMove = false;
    }```

[polar acorn]

You shouldn't add components to prefabs

[hexed nymph]

I tried making a function called "StopThatShi" that stops that but it didn't work

[polar acorn]

That will change the actual prefab file permanently

[hexed nymph]

eish... So how can I add that?

[polar acorn]

Why add the component at all? Sounds like you should just have two prefabs that have the components you want already on them

Then you can choose which prefab to spawn for the player

[hexed nymph]

Its because I made a input setting that changes the input you want for a specific action, and when I tested it it didn't work, so I tried to create 2 scripts, one for player1 and the other for player2

but I'll try making 2 prefabs for the same characetr

[placid shard]

This is more a question but im creating a ray for my interaction system which always points where the camera is looking. I've created some animations for the camera when reloading which rotates the camera. But once the camera is rotated the ray only points forward instead of where the camera is pointing. Does the animation affect the ray ability to find the camera rotation or is my script just possibly bad? (ignore the cool picture)

[cosmic quail]

can you show the part of the script where you shoot the ray?

[sharp bloom]

Any ideas how can I match the position of my mouse and this projected sphere?

        projectedPos = Vector3.ProjectOnPlane(worldPos, new Vector3(0, 1, 0)); //account for camera rotation

I have this currently

[rich adder]

https://unity.huh.how/screentoworldpoint#alternate-methods

[sharp bloom]

I made this script when we had purely top down camera and it worked for that, but now we've rotated it

[sharp bloom]

Hmm using a plane like that might work in this case

[rich adder]

Yeah I do that myself (similar game view) . Imo the best option

[sharp bloom]

Yeah that's a nice method thanks

[livid arch]

https://streamable.com/9qfnix i did something lol

[sharp bloom]

Average ai code

[livid arch]

lol

[rich adder]

cannot help you with AI code

[sharp bloom]

I think you're constantly adding force to your object

Eventually it goes crazy

[livid arch]

all i did was do a raycast down to check for floor collision

its code was very similar to what i already wrote

    {
        Ray playerSpring = new(transform.position, UnityEngine.Vector3.down);
        Debug.DrawRay(transform.position, UnityEngine.Vector3.down, Color.green);

        isGrounded = Physics.Raycast(playerSpring, out RaycastHit hit, springMaxDistance, groundLayer);
        print(isGrounded);
    }```

ohhh i figured it out, it was my camera function i didnt fix.

Hey, Got some help to make a tilt/lean feature, and I have this issue where the camera violently spins around like in the video. How can I fix this issue?

Script: https://paste.ofcode.org/wHpxNYmeWAEeKB4P8NjKhx

[timber tide]

zoom

Looks fine to me? Besides using eulers when you probably want to start sticking to AngleAxis if you're adding roll into the equation

[agile steppe]

why i cant use the SetDestination() method?

[timber tide]

I think what could be happening is you're not lerping to the smallest angle of rotation

[agile steppe]

i dont understand why it doesnt work

[red igloo]

It doesn't not look fine at all as I am making a lean/tilt feature not a "Roll"

[red igloo]

hover over it and read what it says

[timber tide]

wouldn't tilt be x then

z is usually roll

[agile steppe]

it says, it doesnt exist this method

[naive pawn]

read the full thing

[red igloo]

no x is tilting and z is rolling

[timber tide]

targetRotation = Quaternion.Euler(0f, 0f, 15f);```

[naive pawn]

wait what is Agent even from

[agile steppe]

but the method should exist. it is in the official documentation

[red igloo]

@timber tide tilt is z x is roll

[agile steppe]

what should i do?

i used: using UnityEngine.AI;

[naive pawn]

ah wait i thought Agent was a class

[agile steppe]

Agent is a NavMeshAgent component

[naive pawn]

it isn't

it's a BlackboardVariable

Hi, I'm wanting to start my 2D platformer project from scratch, and I want to make sure I do it right this time. I've tried looking up best practices for 2D platformers, and I can't find any clear answer on which type of raycast is better for standard player collision detection.

Simple raycasts, box casts or capsule casts?

[frail hawk]

not sure what you are asking for, the methods you mentioned are more to detect a collider

if you want proper collision detection you´d have to use a rigidbody2D

[rich adder]

use whatever fits the shape of your collider, raycast might be too thin

unless you had a L / R casts on each side of feet

also this assuming you're talking about Ground detection

colliders automatically hit each other without further methods

[mental rock]

my bad, I'm new to trying to make a proper platformer in Unity so its difficult to know what I should be asking and what I should be telling.

I'm wanting to make a 2D platformer that has an emphasis on tight, precise and fluid movement (not a cheap "it'll do" type of collision detection). I'd want the player to be able to detect walls for wall climbing, wall sliding, auto-stepping on smaller steps, etc

I have a gut feeling that something like a boxcast would be too restrictive and non-flexible, and something like a capsulecast would have unwanted interactions on ledges of platforms due to the rounded bottom

I previously attempted this with just simple raycasts but it proved rather buggy so I had to do a lot of unsavoury bandaid fixes that I'd rather avoid this time around

[rich adder]

Sounds like you want to use Kinematic and do your own ground/wall detections

[mental rock]

kinematic yeah, thats what I did and plan on using, its the specifics of the type of casts that I'm worried about

I don't know when or even if I should use things like boxcasts if I'm wanting a large degree of control over movement and collision detection

are they as restrictive as I think they are?

[verbal dome]

Consider this?
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Rigidbody2D.Cast.html

Not sure how you are supposed to depenetrate in 2D though

3D has Physics.ComputePenetration

Someone said in a thread this would be handy https://docs.unity3d.com/ScriptReference/Physics2D.Distance.html

[mental rock]

i don't think ive ever seen anyone use that before

is it standard for 2d platformers?

ive only ever really seen simple raycasts, boxes and capsules

[verbal dome]

I guess it depends on what kind of collision handling you need

[mental rock]

can you elaborate?

im wanting to make a fluid and precise platformer like super meatboy for example. But the character wouldnt be a perfect square

[verbal dome]

Everything that's solid in super meat boy seems to be rectangular

Will your game be like that too?

[mental rock]

this very well drawn infographic might help explain what I mean. I'm wanting a relatively-humanoid player and most enemies will be too

which one is most appropriate

sorry if the last one is inaccurate, idk if thats what a rigidbody2d.cast would look like 😄

forgot to draw the sides on the first capsule onebut oh well

[verbal dome]

Rigidbody2D.Cast isn't that different from just casting all your colliders separately

[mental rock]

so rigidbody2d.cast is purposed for players that are built of, say, multiple box colliders(?)

-# like this?

[verbal dome]

Sure, but that isn't really relevant here, you usually go with a single collider

[mental rock]

sorry if im well off base

[verbal dome]

It does detect colliders that it starts inside of, though

Not sure if other 2D casts do

[verbal dome]

Anyway, you'd likely go with a single capsule or box

[mental rock]

how should I determine which one to use?

like does capsule have any pros/cons over boxcasts

my presumption is that the rounded top and bottom can lead to unwanted movement at edges.

actually do boxcasts work well with slopes at all?

[verbal dome]

Yeah that can be an issue with capsule

[verbal dome]

And that's one with box

[mental rock]

ah i see

[verbal dome]

You didn't answer this

[mental rock]

oh my bad

no they won't be rectangular to a fault. They'll be relatively humanoid like the drawing I put in

I could use a single boxcast as an approximation but I don't know if thats standard practice for a 2D platformer that's trying to emulate the precision of super meatboy (but without the square characters)

I'm unsure whether or not there'd be a huge disconnect between the visuals and the actual collision

[verbal dome]

Let me clarify, I'm asking about the levels/map, not the characters

[mental rock]

Oh

[verbal dome]

What kind of geometry do you expect to see

[mental rock]

Yeah the geometry would be mostly flat floors and walls, etc

[verbal dome]

In any case I would start by using a dynamic rigidbody instead of rolling your own collision detection completely

[mental rock]

dynamic?

Isn't that a no-no for 2d platformers

[verbal dome]

You can still completely control the velocity manually if you need to

But you get collision detection for free

[mental rock]

i'll consider it but I've been set on kinematic due to my need for complete control over the movement and such

there's probably some math you can do with the raycasts and platform normals i assume when using boxcasts on slopes

[verbal dome]

Yeah and that gets pretty complex if you want to have sliding etc.

Imagine a situation like this, where your character wants to move into a surface at an angle. You need to do multiple casts to get the correct final position

Which is what I meant with depenetration

[frozen crypt]

yo whats good

[rich adder]

opposite of bad

[frozen crypt]

so just !bad

[naive pawn]

eh, could be ~bad or -bad or bad^-1 depending on your definition of opposite

anyways, https://nohello.net

ugh that's not one of them

[rich adder]

no dash

[frozen crypt]

anyways can someone help me fix a bug i have

[rich adder]

maybe ?

[naive pawn]

there's so many variations 😔

[frozen crypt]

dont feel like doing allat

[rich adder]

so why are you here ?

[frozen crypt]

just need help with colliding

[naive pawn]

see that last point

get to the point please

https://dontasktoask.com

[frozen crypt]

i saw it chill

[rich adder]

assuming they have ability to read

[frozen crypt]

im lazy

[rich adder]

not a good trait to be a gamedev

[frozen crypt]

anyways i tried detecting touch but doesnt wanna work

[frozen crypt]

dont really care tbh ive been doing game developing for a year just on another game engine with other coding language

no a year but around

close

[naive pawn]

....are you gonna ask your question

[rich adder]

sure but did it teach you how to read properly ? I think no

❔ And don't ask to ask, ask a full question illustrating with screenshots if needed.

[naive pawn]

we still don't know what you need help with

[frozen crypt]

i did ask it

or was it unclear

i tried detecting touch but it doesnt wanna work

[naive pawn]

that's not a question

[frozen crypt]

i tried ai to it didnt work

[polar acorn]

Have you jimjammed the flammistan?

[naive pawn]

that's just a complaint lol

[rich adder]

how we supposed to guess what problem is without knwing the full setup

[frozen crypt]

not really complaint

[naive pawn]

you've given absolutely no info to help you with

we need more context to be able to actually help you

[frozen crypt]

wait lemme get the script

[naive pawn]

we aren't psychic, we aren't looking over your shoulder

info has to come through you

[frozen crypt]

wait

[rich adder]

is your MindReader5000 not working?

[naive pawn]

start with a description of the actual problem
"it doesn't work" doesn't tell us anything; if it did work you wouldn't be here lol

[frozen crypt]

using UnityEngine;

public class Finish : MonoBehaviour
{
    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("Player"))
        {
            Debug.Log("Player touched the object!");
        }
    }
}

i tried doing this

but idk why it doesnt work

[rich adder]

start by putting the log outside If statement

[frozen crypt]

and why?

[rich adder]

so you can test ?

[frozen crypt]

oh

k wait

[naive pawn]

you know now that the full thing doesn't work
maybe it's the if, maybe it's the method not getting called

narrow it down

[rich adder]

if there is no collision at all you know its not the code

[frozen crypt]

well i have isTrigger on so idk what else i gotta do

[slender nymph]

https://unity.huh.how/physics-messages

[frozen crypt]

what that

oh

tutorial

thanks ig

[slender nymph]

not a tutorial. please learn to read. and finish a thought before sending your message. we don't need 4 message spammed in 10 seconds that cover only half of a thought

[frozen crypt]

oke

[placid linden]

I'm making an landing gear and I'm intending to make some conditions to it

1 - check if the landing gear is touching ground, if so, it wont be able to retract/play animation

2 - when it retracts, i want it to disable its own box collider since it glitches with the spaceship and gets thrown away

any tips or help I could have?

[rich adder]

use the collider OnCollisionEnter and OnCollisionExit

or use a script for physic query instead

for problem 2 you can also disable the collision between the two colliders or set the wheels to trigger until you touch ground
(this might be issue if you need OnCollision Enter so that might need a ray for checking ground)

[placid linden]

well, since it will only be able to retract off ground/airborn, I could use the same bool "isGrounded" for disabling the box collider?

[rich adder]

if you use casts sure , disabling the entire collider will prevent collision message though

[placid linden]

casts?

[rich adder]

mhm like Raycast, Boxcast, Spherecast etc.

I would use a sphere/boxcast here

raycast also sufficient if you're okay with only a thin line

[placid linden]

well, I think I could use that (even that I don't know what it is--)

I don't actually need a that big collider for the wheels

[rich adder]

its just a way to detect colliders

[topaz bridge]

Question. I notice that a raycast fired from an object below terrain doesn't hit anything. I assume it's because terrain collision is one way only. Any workarounds for that?

[rich adder]

raycasts also not set to hit backfaces by default

[topaz bridge]

Found a workaround. Big ol' collider.

[rich adder]

select it and press F

also not a code question

[placid linden]

sorryy

thank you though

[mental rock]

Is it normal for it to be difficult to make even a simple collision detection system with kinematic rigidbodies

i feel like im doing something really wrong with my code

[rich adder]

coding your own collision isn't trivial so yeah could be normal

maybe use non-kinematic but with velocity so you can at least use the collisions built in then use casts for other specialities like climb and sliding etc

[wintry quarry]

you'd have to show us what you're doing. "simple collision detection system" is really vague

[mental rock]

from what I know about dynamic vs kinematic, I don't think I can compromise on using kinematic. I need the full control over movement, I just need to get my head around how to do collision detections

[wintry quarry]

It really depends what you mean by "full control" your descriptions are quite vauge

[mental rock]

That was all I wanted to ask at the moment. I've seen so many people code their own platformers with kinematic rigidbodies that I am just left scratching my head at how they've managed to do it

[wintry quarry]

We don't even know what kind of game this is

[mental rock]

It's a 2D platformer, I had spoken about it at length earlier, I just kinda forgot that it's been a while since I provided context 😄

upon rereading the differences and pros vs cons of dynamic rigidbodies, it might be worth trying that instead

[wintry quarry]

If you want to make a kinematic character controller you'd basically just use CapsuleCasts for collision detection

[mental rock]

I was doing that but with boxcasts

What do 2D platformers usually use for the playable character?

kinematic?

[wintry quarry]

there is no "usually"

every game is different

it depends on your specific requirements

[mental rock]

To put it shortly, I'm wanting to try make a 2D platformer akin to Super Meatboy in how it controls

i dont know whether dynamic rigidbodies are designed for that use case

[rich adder]

You can make either one work 🤷‍♂️

[mental rock]

arent there a lot of restrictions with dynamic?

[rich adder]

I could think already a few ways because did something similiar with a dynamic

[wintry quarry]

Rigidbodies give you a lot of the physics stuff for free

[rich adder]

just had to play with physics material / drag

[wintry quarry]

what kind of restrictions

[mental rock]

I read that dynamic rigidbodies lock you into using the same set of physics in all circumstances, etc

[wintry quarry]

Not at all

[mental rock]

aspects like that

[wintry quarry]

You can write code to make it do whatever you'd like

[mental rock]

hmm, i'll probably try to give dynamic rigidbodies a go to see if I can achieve what I'm wanting without hitting any roadblocks related to them

thank you for the help

[wintry quarry]

There are a lot of "limitations" people think of that are actually limitations of "I wrote a very simple script and it doesn't handle XYZ" and not a limitation of Rigidbodies themselves

People in general underestimate how complex character controller scripts are.

[mental rock]

I could've sworn that kinematics was the go-to for 2D platformers due to the lack of preset physics involved

still, i hope to understand it one day because I feel defeated 😭

[wintry quarry]

Every 2D platformer is different though. Mario is very different from N+ or Meatboy and Celeste is different from all of those

The important thing is to just actually understand how the various components work

when you do that, you can do anything you want.

[night mural]

yeah -- if you are stressing about the answer to this particular question, the answer is don't. They aren't that different and you don't know what you need yet, so pick either one and start using it, and that process will teach you what you actually need to know, at which point this question will have a very obvious answer for you

[mental rock]

i was very much under the general impression that dynamic rigidbodies were for when you wanted to have more realistic physics interactions and kinematic was for when you wanted everything to be scripted to your specification

[wintry quarry]

Those two things aren't mutually exclusive

And with the right code you can encroach on each of those things from either entry point.

[mental rock]

I see. I've probably also just internalised some stigma about dynamic rigidbodies as well, like they're a cheaper easier version that you wouldn't use professionally, yknow

but thats just me and the stuff ive probably read very wrong

[night mural]

I would not read too much into any information you have about game dev that isn't from your own experience

it's probably either not useful anyway, or you lack the context for it to be useful to you, and you should just spend a day or two playing with it and it'll all make sense

people put a lot of effort into trying to make 'the right' decision but most of the time there is not one, or you don't know enough to make it yet because it's too early

[rich adder]

you don't know until you know

[mental rock]

in case my attempt with dynamic rigidbodies fails or i do somehow come across restrictions, how would I go about learning the ins and outs of kinematic rigidbodies (specifically geared toward 2d platformers if possible)

[wintry quarry]

find/follow some tutorials to start with I guess. Basically - try them out, try to make something, fail, learn stuff.

[night mural]

Ultimately, you have a thing and you are modifying its velocity over time, either through forces or custom math. It's mostly figuring out the piecs of that that's hard, not applying them to the thing.

[placid linden]

been testing out and reading about raycast on the unity docs and I'm testing their code but it does not detect ground in any way

or even draw any line as it says

[slender nymph]

you have gizmos off so you won't see the drawn gizmos

[polar acorn]

You have six hidden errors. Maybe look at what those are

And yes, gizmos are not drawn in game view by default. Enable them or check in Scene view

[placid linden]

ohh thank you

[polar acorn]

Yep, you can't do GetMask outside of a function

That would mean your layer mask is empty

[slender nymph]

just serialize the variable and assign it in the inspector

[placid linden]

fixed it inserting it inside update(), or would it be better to add it into Start()?

[polar acorn]

Best bet would be to serialize the variable and assign it in the inspector

[rich adder]

[SerializeField] private LayerMask ground

[placid linden]

ohhh thanks!

sorry I'm still pretty stupid to C#

is there a way to make 2 raycasts into the same code? like, create a variable for checking ground and another one for checking whats above the GameObject?

[rich adder]

ofc

[wintry quarry]

You write more code that does the other raycast

you can write literally whatever you want.

[placid linden]

I know but I mean, how to create an variable to the raycast itself?

[wintry quarry]

What does "create an variable to the raycast itself" mean?

[rich adder]

it returns a bool if you want to use that

[wintry quarry]

If you want two different layermasks, you make two different variables

[rich adder]

like you could do isGrounded = Physics.Raycast(etc.

and then make another for whatever

[placid linden]

oh it is a bool?

[rich adder]

yes result if true if it hits a collider

then out is whatever info of the hit

[wintry quarry]

Raycast returns a bool, yes. It says so right in the docs and when you mouse over it in your configured IDE.

[rich adder]

always check the !docs

[eternal falcon]

Documentation

Get the most out of Unity Editor by accessing our documentation!

💻 API

📖 Manual

[placid linden]

well, that was my question itself, so it would be like

private bool isGrounded = Physics.Raycast(down) private bool isAircraftColl = Physics.Raycast(up)

[rich adder]

and yes do make sure IDE is configured it tells you return types

[wintry quarry]

no you wouldn't use private here

private is only for fields

not for local variables

[rich adder]

and methods doesnt get called in field initializer

[wintry quarry]

a local variable is a variable you declare inside a method/function

[placid linden]

I'm pretty confused

[rich adder]

also, notice how here it says if(Raycast) so yes Raycast is a bool inside if statement

[rich adder]

You lack fundamentals to c# thats why

where to declare fields, local variables, functions etc

[placid linden]

well, I have programming basics since I've been in touch with other programming languages, I'm just confused about raycasts themselves

[rich adder]

what about them ?

[polar acorn]

A raycast is simply a function that checks if there's something in a line.

It returns a bool, true if it hits, false if it doesn't

[wintry quarry]

There's nothing special about the raycast in terms of programming. All of your questions have seemed to indicate confusion about C# itself.

it's just a function that returns a bool

there's nothing magical or special that steps outside of normal C# rules about it

[rich adder]

   bool CanDrink(int age)
    {
        return age >= 21;
    }```

if(CanDrink(30))
{ 🍺 }

[placid linden]

got into this

void Update()
    {
        LayerMask ground = LayerMask.GetMask("Ground");
        RaycastHit hit;

        bool isGrounded = Physics.Raycast(transform.position, transform.TransformDirection(Vector3.up), out hit, 3, ground);
        bool isAircraftCol = Physics.Raycast(transform.position, transform.TransformDirection(Vector3.down), out hit, 1, ground);

        if (isGrounded || isAircraftCol)
        {
            Debug.Log("Ground touching");
            Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.up) * hit.distance, Color.red);
        }
        else{
            {
                Debug.Log("Nothing in touch");
                Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.up) * hit.distance, Color.red);
            }
        }
    }
}```

don't know if its the best way to do it but

[rich adder]

are those seperate up and down rays but they're both "ground touching"?

[placid linden]

you took me in there

fixed it xD

[rich adder]

btw why didnt you change this into a field
LayerMask ground = LayerMask.GetMask("Ground");

#💻┃code-beginner message

[placid linden]

fixed it too, sowy

just noticed the best way to debug these would be two if's insted of only one

[rich adder]

if they serve different purpose probably.

but yeah you get the point, if you need another, rinse and repeat

[placid linden]

yes, thank you so much!

also, is there a way to do multiple ones?

[rich adder]

In what sense multiple , isn't that what you're doing now ?

[placid linden]

like this

[rich adder]

yes use loops

[placid linden]

oooh sure

[rich adder]

and a bit of math

[placid linden]

and ++ certain degrees once it runs into the loop right?

[rich adder]

I'm bad at this stuff iirc was something like float angle = i * Mathf.PI * 2 / segments;

im sure if you google rq raycast in circle / segements unity you will find plenty

that outer circle might just be a visual gizmo no clue how that one was done

[placid linden]

ohh no don't worry, it's just for knowledge, but you all helped me a lot already, thank you for your patience! ❤️

[mental rock]

is the only solution to scale up the project? I'm working with sprites as small as 12x32

[rich adder]

@mental rock btw you're in a code channel

[mental rock]

oh whoops

[placid linden]

me again lol, is there a way to keep the raycasts straight down? like, if I rotate the GameObject, it will not rotate too and will maintain the object center but will keep straight down

so they don't tilt with the object too

[eternal needle]

you're probably using the transform to get the vector. you just use Vector3.down https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Vector3-down.html
or in other cases could manually define the vector

[wintry quarry]

the raycast goes wherever your code tells it to go

Tell it to go straight down instead of whatever you're doing now.

[placid linden]

that worked, thank you so much

[wraith condor]

Why is GPU instancing in unity limited to 1000?

That seems really strict

[teal viper]

Possibly due to the limitation of the underlying API. Or they estimated that it becomes not cost effective after that.

Instancing is not free after all. It just shifts the overhead to the GPU.

[wraith condor]

Hmm but batches would be slower then just raising the cap

[teal viper]

On the CPU side perhaps.
Though it's not as much about batches as about setpass calls

[wraith condor]

Idk what a setpass call is

You would have to explain

Do you mean a draw call?

[teal viper]

It's something that sets up the GPU state. Several draw calls can you the same pass. I can't say more than that, as unity is not open source.

[wraith condor]

Oh ok

[teal viper]

Anyways, where did you see about the 1000 limit?

[wraith condor]

A YouTube video

I was looking at Godot multimeshinstance for voxels and I looked up how to do GPU instancing in unity

They said it had a limitation of 1000

I was thinking about using GPU instancing to draw faces instead of cubes for voxels

[teal viper]

Hmm... The only reliable thing I can find is about using the API directly in the code:
https://discussions.unity.com/t/gpu-instancing-count-limit/723510/2

And I'm not sure that applies to GPU instancing that unity does automatically when checked on the material.

[wraith condor]

Also one more thing

Is it possible to draw textures onto another one to create a texture batch?

Last time I tried to I couldn't find a way to draw it to another texture

[teal viper]

Sound like a texture Atlas? In 2d there is a sprite atlas feature, but in 3d you'll have to come up with something yourself, or use an external program, like blender and gimp, or look up some asset on the asset store.

[wraith condor]

I wanted to generate the atlas at runtime from a bunch of smaller textures

Kinda like how Minecraft does it now

[teal viper]

Then you'll need to implement it.

[jolly moat]

For a top down 2D game, if I want the player to have a collider for his attack point, should I create 4 collider objects, one for each direction? How is this usually handled?

[rich adder]

if you rotate player just use 1 infront ?

[past pecan]

ts give me brain aneurysm 💔
I double checked all of my states
I don't know why it's making him walk all funky when I press down
I think it's something to do with the superiority of the statements, but I don't know what to do to fix it

I commented my code

[livid arch]

Is using ai for coding okay?

[slender nymph]

that depends, do you enjoy having shitty code that you don't understand and is a nightmare to extend with further functionality? if so, then yes ai is just fine. if you prefer code that you do fully understand and isn't necessarily bad, then don't use AI

if you want to discuss the pros and cons of ai further then take it to the containment thread https://discord.com/channels/489222168727519232/1352599815770341479

[livid arch]

Thanks

[pure pike]

how would i set a text mesh pro object to 0.00

like with ontriggerenter3d

[rich adder]

make a reference then use SetText method

https://learn.unity.com/tutorial/working-with-textmesh-pro#5f86410eedbc2a00249a4927

[hidden fossil]

whats wrong with this code? i click on a plot and then i place no towers and i click on another plot but if i click that original plot again, it doesnt show the tower menu?

[pure pike]

can you give me a quick example

[rich adder]

start debugging and see what the values are

[rich adder]

did you click the link under it? has code example

[hidden fossil]

values? isnt this like a ui bug or smth?

[pure pike]

i didnt see one, all i saw was clock stuff

[rich adder]

you have a few bools and variables, with some methods running. Check if they do what you expect them to do.. Narrow downt he issue

[rich adder]

clock stuff?

[pure pike]

like making a realtime clock

[rich adder]

ok?

do you know what examples are ?

[pure pike]

yeah?

[rich adder]

soo take the example of how to set TMP text to some value?

the "clock" is irrelevant

replace the value to whatever you need it to be.

[pure pike]

how would i use the "public oject timerStop;" in the ontriggerenter

[rich adder]

use the reference in the method just like you would use it in any other method

also might want to take the programmer pathway in !learn 👇 and the C# pinned in the channel

[eternal falcon]

:teacher: Unity Learn ↗

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

[rich adder]

doesnt look like you declared the proper type

in an example you change the variable also to fit the name that makes sense for your object

[pure pike]

the object is for stopping the timer tho?

i dont code very much

im sry

im too busy to actaully take classes

so i just learn by my friend or just try to make something on my own

[pure pike]

i changed it to game object, and how do i reference it?

[rich adder]

if you're too busy to learn whats required , how do you plan on making this game ?

[pure pike]

idk

[rich adder]

this isnt something you learn overnight lol

takes years sometimes

[pure pike]

can you just help me, i need this script for someone

[pure pike]

ik

[rich adder]

help you how, the page I linked shows exactly how to assign values to TMP, if i tell you words like references How can that help you if you dont know what it is

[pure pike]

no like using the game object ill assign to the field i made, how would i../

nvm

hold on

[rich adder]

the type here is TMP_Text, why in your mind that should get changed to Gameobject ?

[pure pike]

noooooooo

hold

[rich adder]

this literally goes in the OnTriggerEnter script..

replace the name and the value to whatever you need it for

[pure pike]

i want th game object to be the collider in ontriggerenter

[rich adder]

put the script on the gameobject with trigger on it

idk wat you mean the gameobject to be the collider, gameobjects can't be colliders..they contain a component collider

[pure pike]

fine

i didnt want to

but ok

i cant

it interferes with what i want to do

[pure pike]

well how do i use that component as te collider

[rich adder]

AddComponent -> Collider

[pure pike]

its not a thing

theres addcomponentmenu?

[rich adder]

on the gameobject

its a thing

[pure pike]

i have a box collider on it

[rich adder]

the the prefabs for missing script

[rich adder]

ok so is it trigger?

OnTriggerEnter needs the script to be on one of the triggers to get called

[pure pike]

i want a different object than the one the script is on to trigger it

[rich adder]

so put it on that

[pure pike]

put it on what

[rich adder]

look through them and findi it

[rich adder]

on the object that triggers it?

[pure pike]

i cant

[rich adder]

that only works if has a rigidbody

[pure pike]

i dont understand anything dawg

maybe coding isnt for me

[rich adder]

ok solve it by going through the prefabs and finding the one with the missing script

you made lords mobile?

wut?

[sour fulcrum]

Is this some modding type stuff maybe?

[rich adder]

||we gettin to it..||

sounds like they are tyring to decompile or something

you "got it" ?

if you got it then did they explain what the missing script is?

so they give you the project with missing scrips?

possible, meta files shouldnt be touched manually and should be committed to any repo

can't help with decompiled projects #📖┃code-of-conduct

[pure pike]

when i start back the timer, i want it to start from zero, not from where i left off, how would i do that?

[charred spoke]

Show the code. You are obviously not resetting the actual timer variable

[glacial coyote]

Hello friends, I have an issue here. So I'm trying to make my character move on a horizontal axis, however, it's just screaming at me and I dont know what i'm doin'

Shall I also send the code so it's easier to look at?

[pure pike]

thats what im asking, how would i?

[tired summit]

classic error, your gameobject doesnt have rigidbody2d component or you dont reference it when it run

change rigidLink.GetComponent to gameObject.GetComponent and it should be fixed

Thank you! But now it's telling me it can't take parameters

[charred spoke]

Set currentTime to 0 when you stop the timer

[tired summit]

i bet you have something like this
void Update(T _t){}

just remove the thingy in ()

Update() is unity special method you usually dont modify that

with out actual code it's impossible to tell

[glacial coyote]

Click the error and send the code so the kind people can help

[tired summit]

idk your seem like a complete project

i dont really wanna read the whole project :l

[pure pike]

how do i make the game object that i put in this field the collider for the ontriggerenter?

[charred spoke]

These two pictures tell me nothing

[tired summit]

put in ontriggerenter()

timeReset = other.gameObject;

or something like that

[charred spoke]

You need to look up how to reference members from other scripts https://unity.huh.how/references

[pure pike]

what do i do with this?

[tired summit]

read it

[tired summit]

tbh i think it'll be more fast if someone just fix it for you

by the look of it, it quite simple

[pure pike]

well can you do it?

[tired summit]

dm me

I am following a video for being able to shoot pixels and for some reason when I shoot the pixel/bullet just stays in place and doesn't move.
first slide is for the shooting code and second is for the bullet

[night mural]

1. If your version is behaving different, look at the video and figure out where yours is different. It's foolproof.
2. You probably want velocity, not angularVelocity

[gleaming karma]

ok thankyou, its also giving me an error saying no Rigidbody attached to the Bullet(Clone)

[night mural]

I expect that would be because you don't have a Rigidbody attached to the Bullet(Clone)

[gleaming karma]

ye I will look into that lol

I forgot to put Rigidbody2D and had Rigidbody instead

[rare basin]

anyone can help me fix this error

its from HDRP

[sour fulcrum]

you can't get help for what you want here

[coral charm]

Hello,
I'd like to know if it's possible to permanently display an isometric grid in Unity, so I can place my elements according to it rather than the default 2D grid.

Thank you for your help! 🙂

If I want to create an object consisting of parts, e.g., a ship, where the object itself should be rigid, but each part can be damaged separately, how should I stiffen this object? Should I use FixedJoin2d, connected to the parent component, to its neighbor, or perhaps in some other way

[timber tide]

I don't mess around with joints too much, but my idea would be just treat the ship undamaged as a single composite collider, then when objects get damaged do you turn on the physics for those parts and allow them to disjoint

[raw smelt]

I actually not Play disjoint them

Plan "

But every part shold get dng seperatly

[timber tide]

Is there a reason you specified joints? You can just use a single rigidbody otherwise and calculate where the objects have hit via collision point otherwise

composite collider works too if you prefer to use multiple gamesobjects

Hi guys i'm writing a little card game by my own, and i'm about to organize code for card informations, events and effects.
I would like to have the max flexibility out of this system, so i can add new cards without creating a class or a method for each of them individually.

So the question is, do you think writing a simple interpreter is a good idea? so i can write "card code" like this:
IF CONDITION
DAMAGE ENEMY 10
END
HEAL PLAYER 2

also i was wondering how games like hearstone handle this thing

[wintry quarry]

Yes, potentially, but it can quickly get out of hand. You'll spend a lot of time updating the scripting framework itself whenever a novel card mechanic comes in, often sort of "duplicating your work" as you'll need to script the card as well as script the card scripting engine, if you know what I mean.

So the payoff of such a system depends on a few factors like:

• How heavily will card mechanics be reused? The more reuse, the more this pays off.
• How many unique/novel effects are there? The fewer the effects, or the more the effects can be derived from simpler effects, the better.
• Are there other less technical people working on the game for whom this system would simplify things?

I'm working on a similar game right now and sort of decided that just doing the scripting in C# directly is going to work better for my particular game.

[mystic sonnet]

Is there any c# formatter for VSCode? Like black for python?

[modern lagoon]

Great answer thanks!
I am curious about your system, do you have a class for each card effect? Also where do you store this informations? i was thinking about scriptable objects

I don't know exactly what you want, but look into ScriptableObjects if you haven't already. Also i'm pretty sure there is hearthstone-like tutorial series on youtube

[sour fulcrum]

Honestly at that point, maybe just write it in code explicitly

[wintry quarry]

This particular game is not a card game, it's more like FTL with "modules" on the ships. It's not exactly one class per effect it's more like a class per "module" which can be attached to the ship (although some modules share code if they are very similar). It's also early days so it might evolve more. I previously made a card game where I built what you're talking about out of ScriptableObjects with enums everywhere, lists of Effects, etc. I wouldn't necessarily recommend that, it got pretty convoluted. But that one involved one class per "effect type" and sort of a composable "chain" of effects that the card could have.

[sour fulcrum]

One thing worth highlighting is that your example is literally just 4 lines

which is a massive pro

it's easy to see it as a con because it's not working alongside the editor as much but

very readable, very simple
