[slender nymph]

that's called code lens. and it makes it helpful to determine where/when things are being used. why would you want to disable useful debugging tools?

[unreal phoenix]

I don't, I just remeber a time when they were off to the right and not spacing out the text

[slender nymph]

are you certain you aren't thinking of something else? because code lens has looked like that for years

or maybe you're just remembering a time when you didn't have it due to vs code not being properly configured

[unreal phoenix]

It just spaces out the text a lot vertically and drives me a bit crazy

I mean I don't see it's superior over hitting [shift+F12]

[azure zenith]

Can you declare two prefabs?

[fossil drum]

Sure

[swift crag]

I just shift+F12 something if I need to know where something is being used. I prefer to have the code lens off

Although, that's partially because VSCode gives the lens an entire line, iirc

rather than a cute half line

[keen dew]

Same, I just find it annoying. How many times something is referenced isn't really the kind of information that needs to be visible all the time.

[swift crag]

i mostly just care about whether it's used at all

[simple sun]

isnt that the same as doing ctrl+f when having the function marked?

[swift crag]

That would search the current file for things with the same name.

[simple sun]

well, for entire project, its ctrl+shift+f

isnt that the same?

[swift crag]

Text search is still very different.

Text search just looks for matching text.

[simple sun]

well you can apply filters to it to make sure

[swift crag]

References are based on code analysis.

[simple sun]

👍

[swift crag]

So it doesn't matter if I have the word "Hit" all over the place in my code

[simple sun]

thats built in to vs right? not a unity thing

[swift crag]

This will only show me things that refer to this specific identifier

It's in your IDE, yes

so VSCode/Visual Studio/Rider/etc.

[simple sun]

great, might show this in my class

[swift crag]

Text search usually works fine within a single file, but short/common names will cause lots of problems

[swift crag]

I guess you'd say that this is based on semantics -- the actual meaning of your code

[mystic oxide]

thanks took me quite a while, its work fine now

[wooden socket]

i want a prefab to start in front of the player and then disappear when thrown. how would i achieve this

the game is about throwing darts

(3D)

[cosmic dagger]

get the player position then add a few units in front (forward) of it . . .

[wooden socket]

would that be in an void update?

[cosmic dagger]

you place it in your code where you need the dart to appear . . .

[wooden socket]

can i just show u my code lol

[subtle hedge]

Why dose the foot moves only up and down if i add the eight offset

[simple sun]

is there any other code that also affect the position of the leg?

[subtle hedge]

nope, thats the only script in the hole project

    private void Update()
    {
        Ray ray = new Ray(transform.position + (Vector3.up * .5f), Vector3.down);
        if (Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity))
        {
            footPlacement = hit.point + (Vector3.up * heightOffset);
        }

        transform.position = footPlacement;
    }``` i even tyed to do this way'

[simple sun]

can you print out what is being hit

[subtle hedge]

the ray hits the ground only

[simple sun]

is that the only output you get if you move it around?

[subtle hedge]

yes

[simple sun]

ok now do the same but with the offset

[subtle hedge]

without the offset the leg moves how is supposed to but the height isn't, and there is no collider hit appearantly

i removed the height offset also from the ray

[simple sun]

so there is different things being hit depending if you use offset or not?

[subtle hedge]

  Ray ray = new Ray(transform.position, Vector3.down);
  if (Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity))
  {
      footPlacement = hit.point;
      Debug.Log(hit.collider.name);
  }

  transform.position = footPlacement;```

[subtle hedge]

with this code the ground is hit, and the position of the foot gose to where is supposed to, but there is no debug

but with this code it debugs that it hit the ground

the ground is always hit, there are no other colliders in front of the ray and foot is contolled by one script

[simple sun]

have you fact checked that nothing else is being hit?
not just as you assume?

[subtle hedge]

yes, in fact only the ground has a collider on hit, and i lifted the spider up to check

only the ground is hit

my exact problem is that the foot dosen't maintain the position when moved forward or left and right and backwards when adding an offset to it

it moves up and down tho

[queen adder]

can anyone help me with Building my game? i get errors

This is wierd

i never had build issues

[simple sun]

that only makes sense (to me at least) if there are different things being collided with, without you noticing it

[simple sun]

chat gpt can probably help

[silk night]

Would be a good idea to post your errors here so we can help 😄

[upper crypt]

I've been struggling so long with it. I've made a 3d game on unity but the player (sphere) moves (wasd) the opposite direction of what it's supposed to be (w goes back, a goes right), I've tried everything
I suspect that maybe I've created the game in the opposite direction of the camera, but I still rotated the camera by 180, and it didnt work, the player too.
here's the code

// Include the namespace required to use Unity UI and Input System
using UnityEngine.InputSystem;
using TMPro;

public class PlayerController : MonoBehaviour {
    
    // Create public variables for player speed, and for the Text UI game objects
    public float speed;
    public TextMeshProUGUI countText;
    public GameObject winTextObject;
    
    private float movementX;
    private float movementY;

    private Rigidbody rb;
    private int count;
    private bool isGrounded;

    // At the start of the game..
    void Start ()
    {
        Debug.Log("Player position: " + transform.position);
        // Assign the Rigidbody component to our private rb variable
        rb = GetComponent<Rigidbody>();

        // Set the count to zero 
        count = 0;

        SetCountText ();

                // Set the text property of the Win Text UI to an empty string, making the 'You Win' (game over message) blank
                winTextObject.SetActive(false);
    }

    void FixedUpdate ()
    {
    

        // Create a Vector3 variable, and assign X and Z to feature the horizontal and vertical float variables above
        Vector3 movement = new Vector3 (movementX, 0.0f, movementY);

        rb.AddForce (movement * speed);
    }

    void OnTriggerEnter(Collider other) 
    {
        // ..and if the GameObject you intersect has the tag 'Pick Up' assigned to it..
        if (other.gameObject.CompareTag ("PickUp"))
        {
            other.gameObject.SetActive (false);

            // Add one to the score variable 'count'
            count = count + 1;

            // Run the 'SetCountText()' function (see below)
            SetCountText ();
        }
    }

        void OnMove(InputValue value)
        {
            Vector2 v = value.Get<Vector2>();

            movementX = v.x;
            movementY = v.y;
        }

        void SetCountText()
    {
        countText.text = "Count: " + count.ToString();

        if (count >= 12) 
        {
                    // Set the text value of your 'winText'
                    winTextObject.SetActive(true);
        }
    }
}```

a little bigger image

[silk night]

can you expand the last one?

[queen adder]

here

[silk night]

Does any of the errors have any explanation text?

[upper crypt]

oh my god

oh my god

it's been 2 days and you saved me

you're a god, thanks!!!!

[queen adder]

some have a lot of wierd texts

OK ALL of them have wierd texts

[north kiln]

Expand the burst ones and read them

[queen adder]

here is my bui;d setting btw

[subtle hedge]

there is no other thing hit by the ray

[eager elm]

it tells you right there why it doesn't work

[queen adder]

i added VS2019

[simple sun]

only thing i can recommend you doing is
debug all of the information
get as much info from the code as you possibly can
from there, scan for anything strange

[queen adder]

What else do i need?

[upper crypt]

How can I change that code of mine, in a way that if the player touches an object, it loses points? (It can only earn points for now)

[silk night]

Please follow what vertx said above, that might tell you what you need to do

[silk night]

Look at OnCollisionEnter

[eager elm]

in visual studio -> Tools -> Get Tools & Features -> Universal Windows Platform development

*Is my guess

[subtle hedge]

there is nothing really to debug, the offset is alright, the ray hits the ground

[simple sun]

do a ray debug visualiser (displays a 2d ray going from origin to target location)

[upper crypt]

Do you mean online or a channel here? sorry i'm new

[queen adder]

nope

doesnt work

[simple sun]

its an event basically
void OnCollisionEnter(Collision colliderObject)
might not be exactly what he means

[upper crypt]

thank you, I know of it from our lesson i'm just not sure how to work with it, i'll experiment a bit

[queen adder]

ok what do i do?

[north kiln]

Expand the burst ones and read them
Expand the Burst-related errors and read them.

[queen adder]

i need to submit this project tommorow to school

[subtle hedge]

it dose hit the ground 100%

[queen adder]

here is the burst stuff you said

[simple sun]

then idk dude

[silk night]

https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html

[subtle hedge]

i will burn unity to the ground

[upper crypt]

thanks!

[queen adder]

do it

[north kiln]

It's telling you which components you need to install

[queen adder]

how do i install?

[north kiln]

using the visual studio installer

[silk night]

or add module via hub

https://img.sidia.net/ZEyI5/WEwofeBo06.mp4/raw

[queen adder]

what to do now?

[silk night]

Click on modify on 2022

[queen adder]

i used 2019 to make all scripts

[silk night]

Then tick "Universal Windows Platform development" & "C++ Universial Windows platform support for vNNN build toold (ARM64)" + all the others that your error discribes

It just needs to be installed

to have the sdk available

doesnt matter which one you use in the end

[silk night]

Hmm oh wait, your compiler tries to use 2019 if i see that right, well then you might have to modify 2019

[queen adder]

i did that

[silk night]

In the error you posted are 4 packages you need to install

at the top should be a tab where you can look for individual components

use the search bar in there

[upper crypt]

should I write the script in the player's script, or create a new script?

// - instantiates an explosion Prefab when hitting a surface
// - then destroys itself

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public Transform explosionPrefab;

    void OnCollisionEnter(Collision collision)
    {
        ContactPoint contact = collision.contacts[0];
        Quaternion rotation = Quaternion.FromToRotation(Vector3.up, contact.normal);
        Vector3 position = contact.point;
        Instantiate(explosionPrefab, position, rotation);
        Destroy(gameObject);
    }
}``` this for example, do I replace "gameobject" with the name of the object I want it (the player) to be collided with? I'm not good with coding..

[silk night]

If you already have a script on your player you can just plug the OnCollisionEnter function into it, keep in mind, in order to trigger collision events, your player needs to have a Rigidbody component

the term gameObject in any MonoBehaviour returns the gameobject your script is on

[fossil drum]

The cs should be after the triple back quotes by the way. That way you get colors.

[upper crypt]

I copy pasted it as it is from the website

[upper crypt]

so how do I make it so the player recognizes the "enemy"? do I use a tag or something like this? or write the enemy's name in the code somewhere?

[polar acorn]

What is explosionPrefab

[upper crypt]

I don't know exactly how the script works, I took it from the website https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html

I want the player to have a point removed when it collides with an enemy/grenade

but I don't know what to write

[pseudo sable]

is this a runtime error? it doesn't look like it is

[summer stump]

This says you wrote the name in PlayerController. But the code above is ExampleClass..

Did you declare it in PlayerController, or only ExampleClass

[polar acorn]

Where do you define a variable explosionPrefab

[upper crypt]

ok so I wrote this cs void OnCollisionEnter(Collision collision) { ContactPoint contact = collision.contacts[0]; Quaternion rotation = Quaternion.FromToRotation(Vector3.up, contact.normal); Vector3 position = contact.point; Instantiate(explosionPrefab, position, rotation); Destroy(gameObject); } in playercontroller

sorry for any confusion

[pseudo sable]

did you also add the public Transform explosionPrefab;?

[upper crypt]

no

[pseudo sable]

that's your problem then

Instantiate(explosionPrefab, position, rotation); <- on this line it doesn't know what explosionPrefab is because you've not defined it

[upper crypt]

youre right it worked fine now

do i add box collider on the enemy?

because the player goes through it now

[pseudo sable]

whatever has this script will need a collider yeah

otherwise OnCollisionEnter will never happen

[upper crypt]

when i add a box collider

my enemy instantly dies?

idk how

[pseudo sable]

if you have a floor or something with a collider then that will be triggering that method too

[queen adder]

Hello

My AI doesnt go to the target. I use SetDestination that returns a bool -> True if set successfully and false if isnt. I get a returned value "true", but my AI doesnt go to the Set Destination. I'd like some help here

[pseudo sable]

you'll need to interrogate the collision and find out where it came from, the easiest way probably is to add a tag to your projectile (or whatever it is) and check for that, if it has the right tag then do the explosion/destroy logic

otherwise just ignore the collision since it'll be a floor/wall/etc

[young warren]

Can't help without code

[pseudo sable]

not enough info here to go on, will need code examples etc

        //Start timer
        TimerStarted = true;

    }

[queen adder]

sent it

[upper crypt]

what do I tag it as?

[pseudo sable]

whatever makes sense!

[upper crypt]

and also, what do I do after I tag it? I don't assume "tagging" will magically work on its own

[pseudo sable]

no, if you add a tag to your projectile prefab (or however you're doing it), you can do collision.gameObject.tag to fetch the tag of the gameobject that the collider is attached to

then check if that == "Projectile" or whatever you name the tag

[modest rapids]

for (int i = 0; i < 2; i++)
        {
            Vector3 tmpPosition = transform.position;

            switch (i)
            {
                case 0:
                    tmpPosition.y = tmpPosition.y + offset;
                    break;
                case 1:
                    tmpPosition.y = tmpPosition.y - offset;
                    break;
            }
            RaycastHit2D[] hit = Physics2D.RaycastAll(tmpPosition, rb.velocity.normalized, distanceFront, mask);
            Debug.DrawRay(tmpPosition, rb.velocity.normalized * distanceFront, Color.red, 0.2f, false);
(slightly more code below)

is there a better way to code this instead of a switch?

[upper crypt]

where do i add this? collision.gameObject.tag

sorry im really bad

[pseudo sable]

oh sorry, inside the OnCollisionEnter method, the Collision collision parameter that gets passed in is details about the collision, collision.gameObject is the other gameobject that's involved in the collision (not the gameobject that the OnCollisionEnter method is on

[modest rapids]

gameobject.tag = tag from the gameobject this script is on

collision.gameobject.tag is the tag from the object that was collided with

[queen adder]

could anybody pls-

[upper crypt]

where do i place it?... 🥹

collision.gameObject.tag

[pseudo sable]

collision.gameObject.tag inside that method will be the tag that you're colliding with, that's the hint! what did you name your projectile tag?

[fringe pollen]

Are there any errors? Have you baked a nav mesh? Is your target within the nav mesh bounds? Does your AI have a path they could take to get there meaning that the path isn't blocked or the AI isn't isolated from the target?

[upper crypt]

I tagged it as "Enemy"

[queen adder]

Are there any errors? No
Have you baked a nav mesh? Yes
Is your target within the nav mesh bounds? Yes
Does your AI have a path they could take to get there meaning that the path isn't blocked or the AI isn't isolated from the target? Yes

Ima try smth rn

[pseudo sable]

okay, so in OnCollisionEnter, collision.gameObject.tag will either be "Enemy" (if an enemy has touched the player), or "" if something else has

so you can check for if the tag is enemy, and then do whatever you like, or more likely if its not enemy, do nothing

[upper crypt]

like this?

sorry

[pseudo sable]

okay so probably worth understanding what exactly that example code is doing, going line by line:

1. fetch the contact point of the collision
2. fetch the rotation opposite to the contact point (i think, i'm rubbish at rotations)
3. fetch the position in space of the collision contact
4. create an instance of an explosion prefab at the position and rotation from above
5. destroy this gameobject
   the question is, when do you want this set of instructions to happen? on every collision, or only on collisions with the enemy?

[polar acorn]

Show the logs you're getting and the order you're getting them in

Turn off collapse if it is on

[pseudo sable]

to sum up those 5 lines i described, it makes an explosion at the collision point and deletes this gameobject

[queen adder]

mk

[upper crypt]

I just want, whenever the player touches the enemy, the player's points get reduced by 1 each time

but I don't tknow how to do that 😭 I don't understand the collision examples i find online

[pseudo sable]

yep! will get to that but it's important to understand the code that you have just now rather than getting ahead

if you understand what you have it's easier to understand what needs to change

[upper crypt]

I agree

[pseudo sable]

so at the moment, when the player touches any collider, it will create the explosion prefab and delete itself right?

be that a floor, wall, etc

[upper crypt]

well, that's not what I want

but currently, when I start the game, the enemy instantly dies

somehow

[pseudo sable]

i know but i'm saying that's what's happening right now with the code you have

[polar acorn]

So log the object you collided with to see what is hitting it

[pseudo sable]

so the next step towards your goal of "take a point away when the enemy touches the player", is to adapt your code so that the explosion/delete effect only happens when an enemy touches you

then after that, we can change the explosion/delete to be "remove a point"

so, going back to what i was saying before, inside your OnCollisionEnter method, the collision variable lets you see the tag of whatever gameobject touched you, accessible through collision.gameObject.tag - you want it so that your code in OnCollisionEnter only runs if the other tag is "Enemy"

var otherTag = collision.gameObject.tag; could be the first line in your method, to poke in the right direction

[upper crypt]

code works but the enemy dies instantly without doing anything

[pseudo sable]

there's more to write, but it's worth trying to figure it out, essential programming skill!

[polar acorn]

#💻┃code-beginner message

[upper crypt]

how do I log it?

[pseudo sable]

Debug.Log("some string") is the method for logging

[polar acorn]

Debug Log should literally have been the first line of code you ever wrote in unity

[upper crypt]

i think i got it

[rich adder]

is your IDE even configured

[upper crypt]

ide?

[rich adder]

VS

[upper crypt]

visual studio?

[polar acorn]

the thing you write code in

Are your errors underlined in red

[pseudo sable]

okay so you can do a Debug.Log(collision.gameObject.tag) in your OnCollisionEnter method to print the tag of the other gameobject (spoiler, it will probably be an empty string if it's the floor and it doesn't have a tag)

[upper crypt]

I only have this now

[rich adder]

hmm this would not underline in the code editor as its a runtime error

you have to check inside the VS when you write something incorrect does it underline it red ?

[upper crypt]

this for example?

cuz in VS it says no issues found

[rich adder]

right this should show in VS

[upper crypt]

i did this on purpose

[pseudo sable]

they're wondering if you look at that line in VS, is there a red underline on it?

at the end of the line

[polar acorn]

Then you need to configure your !ide

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code

Select one:

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

[polar acorn]

So it shows errors as you make them

[cosmic vigil]

is it needed to do that config even if all is running good? or is it just if your ide is not working proper with it, a bit confused now

[polar acorn]

If errors are underlined in red in your IDE, it is configured

If not, then do it

You don't have multiple coroutines stacking?

Then I would first try to fix that Animation Event error you're getting. An error could be preventing your code from executing. It's unlikely but might as well eliminate it as a possibility

Either remove that animator event or assign it a function

[queen adder]

YOOOO

I Exported the game

YES!!

[upper crypt]

there is "wintext" how can i write more than 1 "wintext"? is there like, an endtext/losetext?

I want to have a text show up when the player loses

{
    countText.text = "Count: " + count.ToString();

    if (count >= 12) 
    {
                // Set the text value of your 'winText'
                winTextObject.SetActive(true);
    }
    if (count < 0)
    {
     
        winTextObject.SetActive(false);
    }
``` something like this

[wintry quarry]

There's whatever you want

you can write the code to do anything

you could also just use a single text object and change what it says

[royal osprey]

guys, how to make a camera movement like swipe left/right with bounds?

[upper crypt]

i just dont understand

how can I add the option of a "losetext"?

[polar acorn]

wintext is just a variable you made

If you want more text objects, make more

That's not a built in Unity thing

[upper crypt]

I changed the code a bit but i don't see "losetext" being created 😦

[polar acorn]

Show where you created it

[upper crypt]

Ok I did it! I just didn't make the public line

Now it shows up 😄

[wintry quarry]

it should be TMP_Text, not GameObject

well actually I guess if you're just calling SetActive GameObject is fine

but WinText is a TMP_Text

[upper crypt]

I just tested it, it works

[wintry quarry]

probably best to keep them consistent

[calm osprey]

anyone familiar with InputManager? I was able to make it so when I press WASD my character moves and changes to the running animation, but I also need a transition into the idle animation when I stop moving.
I already have a condition set, I just don't know how can I code "if I press nothing, do this".

[rich adder]

if(inputs != Vector2.zero)

nah fr you gotta show the code

[buoyant knot]

InputSystem is worth learning. Even if learning it absolutely sucks

[polar acorn]

Check if an axis is zero (or if the absolute value of an axis is less than some "deadzone" value you decide on)

[rich adder]

ohh isn't inputmanager the old one?

[buoyant knot]

idk. I thought it’s just called Input

[polar acorn]

it is

[rich adder]

oh idk I thought it was Inputclass/Inputmanager vs InputSystem

ah ok

[calm osprey]

in Unity it's called InputManager

[polar acorn]

InputManager is the old system, accessed via the Input static class

[upper crypt]

how to make it so the game restarts after 2 seconds, and NOT instantly?

[rich adder]

love the names Unity uses

[rich adder]

a timer

[polar acorn]

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

[buoyant knot]

or async

[rich adder]

Task.Delay barely works in unity

[buoyant knot]

Coroutines are good for waiting for specific parts of a frame of Unity’s calculations.
Async works outside unity, and lets you return values

That’s the tldr

[polar acorn]

But it's also a bit of an "infection". More and more of your code will need to become async to interact with it and it's a lot harder to just plop into a project for a single use

[rich adder]

yeah async is a double edge sword

[atomic bison]

hi guys!

[polar acorn]

It's like a zombie virus

[atomic bison]

with unity inapp 4.9.3 we are safe?

im using Version 4.9.3 - June 14, 2023 of inapp purchasing from unity

[rich adder]

whats that? is this coding related?

[atomic bison]

the code of system purchases is not?

[rich adder]

this isn't a specific coding question

[polar acorn]

If it's a code problem, show code

[buoyant knot]

in general, once you start with coroutine/async, it is hard to switch

and a lot of unity devs had issues migrating out to other engines because they were used to Coroutines

[rich adder]

Im glad unity has entry points to async /IEnumerator

private async void Start() | private IEnumerator Start()

[upper crypt]

Last assistance please

When the player falls in a hole, the game restarts

but when I tried to make it so when the player's points go below 0, it doesn't restart

[rich adder]

this alone isn't helpful

[upper crypt]

what more should I give? the code?

[rich adder]

thats a start

[upper crypt]

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

public class ReloadScene : MonoBehaviour
{
    void OnTriggerEnter(Collider col)
    {
        if (col.CompareTag("Player"))
        {
          
            Invoke("RestartScene", 2.0f);
        }
    }

    void RestartScene()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().name);
    }
}
``` this is for when the player falls down

it restarts after 2 seconds

I tried to do this for when the player's points go below 0 ```cs void SetCountText()
{
countText.text = "Count: " + count.ToString();

    if (count >= 12) 
    {
                winTextObject.SetActive(true);
    }
    if (count < 0)
        loseTextObject.SetActive(true);
        Invoke("RestartScene", 2.0f);

}```

[fossil harness]

Are coroutines only ideal for things tied to the frame rate like animations?

[summer stump]

No

Good for lots of things

[fossil harness]

Can you run them on the FixedUpdate cycle? I was looking over the execution order and saw they fall under Update so I wasn't sure

[summer stump]

Afaik, they just run after update

FixedUpdate is a whole different cadence

[slender nymph]

you can yield return new WaitForFixedUpdate to continue right after the next FixedUpdate

[rich adder]

so you were suggested coroutines and you didn't use them.?

also where is SetCountText even called at

[fossil harness]

Oh hell yeah- is there a list of the various yields?

Edit: Also when you schedule the coroutine, I figure it's like calling the method immediately which then continues until it hits a yield return?

[upper crypt]

I just used it by searching around

it's working now thanks

[ashen ferry]

is it possible to declare some kind of method in class and in its constructor take in implementation of it as a parameter lol

like if I declared Action type and I could pass in Action but I want to keep implementation inside class

[slender nymph]

wdym by "keep implementation inside class"

[ashen ferry]

https://hatebin.com/scopwfdtru this imaginary example but instead of making up methods outside class and passing them in have one inside it

idk how to explain

like legit change how that method behaves ig

[slender nymph]

i genuinely do not understand what it is you are trying to achieve. the only way to pass methods around is with delegates like Action

[pseudo sable]

yeah what's the problem you're trying to solve?

[ashen ferry]

I need 4 instances of class with method which does in each of them almost exact same thing

but like math stuff I cant make base implementation then override in child and add onto it or something

[slender nymph]

i'm just gonna drop this here and hope you actually read it https://xyproblem.info

[eternal needle]

It doesn't make sense to take a value from constructor and also keep that implementation purely in class

[ashen ferry]

I imagined this like append this code to this method

kinda thing

[pseudo sable]

why do you need the 4 instances that do slightly different things, probably going to need an example because it really smells like @slender nymph s link

[eternal needle]

Instead of obfuscating what you're trying to do by showing fake examples, just show what youre doing with the real problem

Because right now it just sounds like you need a delegate and that's all

[pseudo sable]

public void SomeMethod(Action someExtraAction)
{
   // Do common things
   someExtraAction.Invoke();
}

this will do what you're describing there

as far as keeping the implementation of the extra action in the class, you could define the actions you want inside the class, and have the callers use them like instance.SomeMethod(instance.ExtraAction1)

Guys, i wanna center my wheel as the same center of my car, how i can solve this?

Like, reseting the Pivot for the center of the wheel

[wintry quarry]

Start by switching this to Pivot so you can actually see what's going on

[rocky canyon]

u can use empty containers.. and adjust the model as a child to represent where u want the pivot.. and then use the parent's pivot (center)... or you can pull the models into blender or some other 3d software to adjust the pivot urself

[quiet dune]

Hi, strage behavior with NavMeshAgent.destination: I have a Vector3 "destination", where x = 512.0001, that i assign to a NavMeshAgent.destination, but the destination than reads a Vector3 where x = 512 without the .0001. Afterwards, when checking navMeshAgent.destination == destination, it returns false. I want to check at a later time, whether navMeshAgent.destination equals the destination i (might have) set earlier, but this behavior screws that up. Any ideas on that?

[languid spire]

Never check float values for equality

[summer stump]

Never use == with float comparisons

Check if the distance is below a threshold

Or use Approximately
https://docs.unity3d.com/ScriptReference/Mathf.Approximately.html

[buoyant knot]

== and floats are bad juju, unless you use == 0f to check for having assigned a zero, and not having changed it at all

[quiet dune]

Ahh yes, i read that before. Thanks for the advice! I'll try using Approximately

[buoyant knot]

i find unity makes float == work somehow, but it’s still pretty bad

Q: Is there a light way to sort (usually very small) subsets of lists?

How i can center my wheel?

[slender nymph]

#💻┃code-beginner message

[sour wren]

I centered it in blender

[sour wren]

BUT NOOOOOOOOOOO

[rocky canyon]

u have to Apply the transform

and then re-export it as a fbx, obj or w/e

if u did it correctly it'll show the new pivot when u swap into Pivot mode as someone already posted

changing that to Pivot

[buoyant knot]

When you get multiple hits from a Cast, is it sorted by distance?

[rocky canyon]

i think, in order of what it hits first

not 100% on that though

[buoyant knot]

one more cast-related question: If i cast and hit something multiple times, do I just get the first result?

example

[languid spire]

The reason that Unity writes documentation is so that you can read it

[buoyant knot]

cool. how about this method?
https://docs.unity3d.com/ScriptReference/Collider2D.Cast.html

[languid spire]

As the size of the array is decided by you the results are most definitely undefined

If a project is halted by a break point, is there a way to prevent the unity editor from locking up?

[orchid trout]

I moved some monobehaviour .cs code around through the project window and now suddenly none of the moved code is able to find types and namespaces that it had no issue with before moving it - why is this the case, how do I fix it and prevent it from happening again?

none of it was editor code and I didnt move it out of the project or out of assets yet somehow it cant find the rest of the code and this has never happened to me before

[azure zenith]

I am creating a game where you splat fruits. I would like to display a splat effect when you splat the fruits, how would I do this? I have the splat prefab

[orchid trout]

visua; studio can't even find the code that is being referenced when I search the entire proj for it, but its not been removed from the proj I even have the other files OPEN in visual studio

[polar acorn]

It is likely that one or both of them have changed Assemblies. If your project uses Assembly Definitions, each one contains only its own folder and any child folders, with each file belonging to only one assembly. You can set references in the inspector for one assembly definition to reference the other. In this case, whatever assembly definition this script belongs to needs to reference whichever one UIProto_ReceiveInputs belongs to

Also, if Unity doesn't have any issues with these and it's purely in your IDE, consider regenerating project files so it knows the new locations of those files

[unique willow]

I'm trying to make a very basic script that sends you to another scene when the enemy collides with the player but for some reason it's not working. Are there any noticable issues?

[orchid trout]

How would I determine if we're using assemblies definitions? We're using plastic as a versioning software if thats related?

[polar acorn]

The Three Commandments of OnCollisionEnter:

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

[orchid trout]

code team confirms Assembly Definitions are in use

[polar acorn]

You would look for any files with the extension .asmdef in the assets folder

[unique willow]

Both have colliders, aren't set as triggers, and both have a rigidbody

That's how they move in other scripts

[summer stump]

Is the scene called Jumpscare?

[polar acorn]

So, each script "belongs" to a single assembly definition. It would belong to the "closest" one in the file system. If it's in the same directory, it'd be long to that. If there is not one in its directory, but in a parent directory, it'd belong to that one

[unique willow]

yes

[summer stump]

With the exact same capitalization

[unique willow]

Wait I think I figured it out

Typically it spits an error when I forget to add it to the build settings

So I figured I already did

[orchid trout]

I see, and by moving the script ive broken that

[unique willow]

Ok now it works

[polar acorn]

Yep. UIProto_ReceiveInputs belonged to an assembly defintion that this script's assembly definition had a reference to, and now it's been moved to one that does not

(or the other way around, this script moved into a different assembly definition that does not have a reference to the one UIProto_ReceiveInputs belongs to)

[buoyant knot]

usually the point of the breakpoint is to basically freeze the state of the machine. Not locking up the unity editor would allow scripts etc to change that state while you’re looking at it

which is not acceptable.

[swift crag]

Unity doesn't do anything special for float. It does, however, give some wiggle room when checking if two vectors are equal with == https://docs.unity3d.com/ScriptReference/Vector3-operator_eq.html

[swift crag]

The game and the editor are running on the same thread. So, no

[buoyant knot]

maybe that’s why I thought it would work

[swift crag]

I check for float equality when I am using something like MoveTowards

It will reach an exact value.

[quiet dune]

@buoyant knot @swift crag I mean just to be able to select game objects, to see their stats, where they are, their gizmos etc. Not having the "game" run or change anything

[azure zenith]

I am unable to see my debug.log messages

[slender nymph]

that doesn't sound like a code issue. but you have probably hidden them in your console

I am sure the function works so I don't know why the message won't display in the console

[slender nymph]

you have probably hidden them in your console

If you want to display effects after you slice a fruit, you would instantiate it, right?

[zealous oxide]

hey friends. in one of my gameobjects scripts i'm trying to instantiate a prefab but the script doesnt seem to find said gameobject/class(?) [despite the desired script having the same name verbatim]. i've tried to drag the script/gameobject prefab into the inspector of the script & game object doing the instantiating but it doesnt let me drop it in. the wierd thing is that i've managed to make this work on 3 other objects/scripts but i cant remember how

[slender nymph]

I do not see a KingsForkProjectile component

[zealous oxide]

are you able to elaborate please? KingsForkProjectile is both a script and asset, verbatim, in my assets folder

[slender nymph]

or was that other prefab not the object you were trying to drag into the first object?

[slender nymph]

the name of the prefab is irrelevant

[zealous oxide]

the crescent dart controller prefab was an example where i did manage to get this working

[slender nymph]

okay so show the object you are trying to drag in

[summer stump]

None of the pictures showed the KingsForkProjectile

[zealous oxide]

i've just had a look at the projectile prefab i wanted to spawn in and realised i hadnt actually dragged the corresponding script onto it, i had gotten a bit ahead of myself. thats actually fixed the issue. thanks

[azure zenith]

This is so weird

I have a class and my game works without it

Like wth

[polar acorn]

I've been working a little bit on refactoring the code for my player. I'm trying to get the health management logic outside the player class and onto a class of it's own.

I feel like I am doing something really wrong here.

Can anyone point if that's how composition should be achieved?

public class HealthManager : MonoBehaviour
{
    public void SetHealthToMaxHealth(int currentHealth, int maxHealth) {
        currentHealth = maxHealth;
    }
    
    public void ReceiveDamage(int damage, int currentHealth, int armour){
        if (armour != 0 ) {
            damage -= armour;
        }

        if (currentHealth - damage < 0) {
            currentHealth = 0;
        } else {
            currentHealth -= damage;
        }
    }

    public static void DamageObject(Collider other, int damage) {
        DestroyableObject obj = other.gameObject.GetComponent<DestroyableObject>();
        obj.ReceiveDamage(damage);
    }
}

[polar acorn]

What is the issue specifically?

And what is this static function hoping to accomplish here, it doesn't seem to have anything to do with the HealthManager at all so it probably shouldn't be here.

[summer stump]

Earlier you were asked to show the console. It is possible to hide logs, so that could be the reason too

[short hazel]

SetHealthToMaxHealth and ReceiveDamage do nothing. The variables you're operating on (eg. currentHealth you set to 0) are copies of the variables you passed when calling the method

Their new values will be discarded when execution exits the methods

[silent obsidian]

That's what I was trying to ask exactly but my english won't help me, how should the logic for systems such as this be handled?

[vocal glacier]

Does anyone know why I can't drag muliple audio game objects from the Hierarchy window to the Project windown in Unity 2018.1.9f2? I am trying to create prefabs of audio to put in assets bundles for VAM. All the documentation for Unity says I should just be able to drag muliple GameObjects into the Project window from the scene and it will make a prefab for each object. I get a red circle with a slash that indicates this action is not allowed. I can only drag one object at a time.

[silent obsidian]

My intuition tells me that i should somehow pass a reference

[short hazel]

Example of the faulty system:

void A()
{
    int health = 100;
    Damage(health, 10);
    Debug.Log(health); // -> 100, because when passed to 'Damage', a copy of the value is made.
}

void Damage(int health, int damage)
{
    health -= damage; // edits a copy of the variable
}

You need to have the current health and armor as class variables instead, to fully separate them from the other scripts

It's possible to pass-by-reference, but for a fully composition based model, the variables related to health must be offloaded to the health script

[silent obsidian]

@short hazel How could I offload variables in a manner that would allow the HealthManager script to be reusable?

I think doing something like GameObject.find("Player").GetComponent<Player>().health is not the right answer.

[short hazel]

You'd have a Player script and a Health script aside on the same object

Then Player could serialize a variable of type Health, so you can drag-drop the health script onto the player script, in the Inspector

[silent obsidian]

public class Player : MonoBehaviour
{
    [Header("Combat Stats")]
    [SerializeField] private int currentHealth;
    [SerializeField] private int maxHealth = 100;
    [SerializeField] private int armour = 33;
    [SerializeField] private int damage = 25;
    [SerializeField] private HealthManager healthManager;

    void Start() {
        healthManager.SetHealthToMaxHealth(currentHealth, maxHealth);
    }

    void Update() {
        if (Input.GetKeyDown(KeyCode.F)) {
            HealthManager.ReceiveDamage(55, currentHealth, armour);
        }
    }

So it should look something like this?

[buoyant knot]

is the most lightweight way to implement BFS a queue?

[silent obsidian]

oh actually it does not make sense because I would still be passing a value.

[short hazel]

Good start, now you can move these directly in the HealthManager class:

And the armor if it makes sense

[silent obsidian]

But what if I would want to reuse the HealthManager for an enemy (that has different values. E.g: maxHealth = 200)

[short hazel]

Then you go in the enemy's inspector and change the value to 200

It's a separate script instance compared to the one on the player, which will stay at 100

[silent obsidian]

Ohhh right because it's a serialize field. Okey, I finally understand it.

Thank you a lot!

[short hazel]

The 100 you set in code is the default value that will be set when you attach the script for the first time. Once you modify it in the Inspector, it's not used anymore

Inspector takes precedence over values set in the code (for field initializers like you have here)

[silent obsidian]

Wait, actually can you reference a script through a SerializeField? or the only way is through getComponent<>()

[polar acorn]

Yes, that's how you should be doing it

[silent obsidian]

I think it only allows me to point to the object HealthBar

[polar acorn]

Does HealthBar have a HealthBarScript on it

[silent obsidian]

it does

[polar acorn]

Then you are referencing the HealthBarScript

[silent obsidian]

oh, thanks

[fossil harness]

I believe so, yes

[last grove]

how would I set the players orientation equal to the slope they are standing on while still keeping them going in the same direction? transform.up = slopeInfo.normal + new Vector3(0, playerCam.eulerAngles.y, 0);This is what I have right now and it resets the player to the axis of whatever part they're standing on

[last grove]

is it possible to get the y value of a rotation for 1 frame and not have it update after?

[eternal needle]

yes, just store it in a float

[last grove]

like this? float prevLookDirection = playerCam.rotation.y;

[eternal needle]

well technically yes based on what you asked, but imma go ahead and assume this isnt what you want. A rotation is a quaternion, quaternion values arent gonna be what you expect so you probably want the euler angles

[dawn sparrow]

What's the easiest way to check if any particular bounding box is in a cameras view frustum, with no regard for efficiency?

[silent obsidian]

I'm trying to learn the new input system, is there a significant difference between messages / events?

[buoyant knot]

afaik, Messages look through a bunch of classes for a method of a specific name

an event is a delegate. When the delegate gets invoked by myDelegate?.Invoke();, any function added to the delegate gets called

think of a delegate like a list of functions. You add/remove functions from this list, to change what gets called when .Invoke is called

make sense?

example:
public event Action OnJumpButton;

I can add:
OnJumpButton += Jump;
OnJumpButton += SelectMenuItem;
OnJumpButton += MakeJumpSound;
….
OnJumpButton -= Jump;
OnJumpButton += Swim;

delegates are fast because you are giving the delegate all the deets of what to call before it needs to get called. Messages need to sift through to go find targets. Delegates don’t have the searching bs

Actions are delegates, btw

event makes it so you can only +=, -=, and .Invoke it

[silent obsidian]

Are there any specific factors to be taken into account when choosing for which behavior to go for? As I've read through the documentation and also your explanation I have a feeling that the events system might be a better fit for more robust games.

[buoyant knot]

it is

I only use messages when Unity forces me to, because of OnCollisionEnter/Exit

also, when you ctrl+R to find all references (to find everything activated by a specific message), good luck. That shit doesn’t work because it’s just a bunch of different functions that just happen to have the same name in different classes

with delegates, you are calling += etc on that one variable. So Ctrl+R to find all references directly takes you to all the different scripts that are getting triggered

i cannot stress enough how huge that feature is

[dawn sparrow]

Okay, i figured this out with GeometryUtilities. It returns true if any part of the bounds in in the camera frustum, which is great, but how can i check for when the ENTIRE bounds in contained within the frustum?

[buoyant knot]

InputSystem is a more complex use case because you are also playing with parsing InputActionCallbackContext objects

but the core of delegates is simple

[silent obsidian]

Do you happen to know of any good resources that covers how to implement the new input system w/ events?

[buoyant knot]

i learned from youtube. and it was painful

there are many tutorials tho

I recommend you try out basic event delegates first

[summer stump]

Have you used a button in unity before? And set up the OnClick callback?

It's quite similar to that

You just get a CallbackContext instead of something you explicitly pass.

And the Context is a struct with values

[buoyant knot]

General workflow:
using System;
In Class1:
public event Action<int> OnEvenNumber;

int i = 0;
void Update() {
i++;
if (i %2 == 0) // if i is even
OnEvenNumber?.Invoke(i);

}

[static cedar]

What are events?
I've been using delegates and never really quite understood events.

The docs just say you subscribe and then stuff.

[silent obsidian]

Not yet sadly

[buoyant knot]

Class2:

void PrintMe(int i) { Debug.Log(i);}
void Start() {
GetComponent<Class1>().OnEvenNumber += PrintMe;
}

those two classes together will, every frame, increment a number in Class1, if it is even, it invokes delegate, Class2’s PrintMe method gets called on that input, and it prints that number

Action (no <T>) just takes no arguments

understand?

[buoyant knot]

events are delegates where you only allow +=, -=, and ?.Invoke()

[silent obsidian]

I kinda get it, they should hire you to write the docs imo

[outer coral]

Is there a simple way to wait for a UI button onClick event to trigger in a coroutine? E.G.

private IEnumerator doStuff(){
//do stuff
yield return new WaitUntil(/*Wait for the ui button press onClick to fire*/);
//do more stuff
}

I looked online, couldn't find much. Help is appreciated thanks!

Really would rather not keep a bool that gets turned true when the button is pressed... seems inefficient and messy

[buoyant knot]

[silent obsidian]

Thank you!

[static cedar]

So I can just encapsulate and it'd be the exact same thing?

Essentially.

[buoyant knot]

event allows fewer things than normal delegate

a normal delegate lets you fuck with the list of methods in multiple ways

events force that to not happen

so you don’t need to worry about one random class totally fucking up the delegate

[static cedar]

mydelegate val1 = null;
myevent val2 = null; //not allowed.

Ok.

[buoyant knot]

if you have only been doing +=, -=, and Invoke(), then it would be interchangeable

event is a modifier

you can have public Action myAction1; and also public event Action myAction2;

it’s like a public/private access modifier almost. applying the event keyword blocks several things from being allowed

but it’s only blocking because you are telling it to block it, and not because it can’t do it.

[static cedar]

Why the hell did the docs go through saying it's a subscription thing and didn't really mention the differences between a event and a normal one that much?

[buoyant knot]

+= is called subscription

-= is unsubscription

you (un)subscribe functions to the delegate

[static cedar]

Those are terms I'm more acquainted with JS and AS.

But yeah ok.

[buoyant knot]

delegates just have a lot of terms and shit that make them harder to learn

[polar acorn]

https://gamedevbeginner.com/events-and-delegates-in-unity/

[buoyant knot]

there are events, actions, delegates, functions, lambdas, subscription, and unsubscription. And some of these are similar, but slightly different

[teal viper]

Actions and Funcs are just types of delegates. Events are a programming pattern.

[static cedar]

One more question, are delegates considered a collection?

Ok chat stopped.

[teal viper]

No

They do have some kind of linked list internally though

[buoyant knot]

they don’t count as a collection, but they function as a collection where you have zero access to the contents

you can’t know how many, you can’t do any sort of indexing. You can’t even guarantee any sort of sorting (that’s not in the spec)

they are a collection in the abstract sense where they function as a container of functions

but you don’t get things like .Contains, delegate.Count, delegate[5], delegate.Sort, deegate.Concatenate…. none of that is a thing.

[eternal needle]

the delegates are chained together through magic 🪄
if anyone has info on how they're currently chained id love to know as well. I only heard of some implementation that existed 10 years ago

[buoyant knot]

as far as we understand, the critical thing is that ordering within a delegate is not a part of the spec

so if you need A to happen before B, and both are in the same delegate, you can’t actually enforce that order

[eternal needle]

i would go with the bool you said was "inefficient and messy". Its a bool, it is neither inefficient or messy.
A string based search for IsInvoking is DEFINITELY messy

[static cedar]

How does the == operator work?

[buoyant knot]

it does whatever it is defined to do

it needs to be implemented on a class-by-class basis

[cosmic dagger]

Nah, delegates are method references. What you're talking about is that they can be chained (linked) together . . .

[buoyant knot]

they feel like a collection of functions, without actually being a collection

[outer coral]

How is it a string based search? It's a built in function in Monobehaviour. And yes it is messy to have a bool for everything in my opinion. Hurts readability for me

^i'm not using the parameterized method

yield return new WaitUntil(() => myButton.IsInvoking());

[eternal needle]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.IsInvoking.html
hm i only saw the first declaration, i see now the one without any params

[cosmic dagger]

@static cedar You're thinking about the multicast delegate. I believe it overloads the += and -= operator where they add to an internal collection . . .

[static cedar]

[cosmic dagger]

The methods are invoked in the order they were added . . .

[buoyant knot]

you’re confusing her

basic vanilla delegate is like a bucket of functions. You throw functions into the bucket (or pull them out), and call them all at once

they technically have an order, but order isn’t a part of the language specification, so that COULD change at any time

[swift crag]

you should not depend on the order, yes

[buoyant knot]

they keep an internal collection, but that is an implementation detail that you do not get access to

it’s like a black box. you don’t get to look inside

[twin bolt]

I want to make a elevator that will move up to a set position, Should i use Animation or .movetowards, to prevent issues with the player following the elevator, or the camera bugging?

[buoyant knot]

MovePosition and MoveTowards

[swift crag]

the important question is: how does the player move?

[buoyant knot]

elevator should probably have a kinematic rigidbody

[twin bolt]

Using Rigidbody, but i want the player to move with the elevator.

[twin bolt]

Ok thanks

[buoyant knot]

is player dynamic or kinematic rb

[swift crag]

A kinematic rigidbody elevator ought to be able to push the player correctly, then

Assuming the player is not kinematic.

Make sure that you're only moving the elevator via the rigidbody

[twin bolt]

so .movetowards wont work?

[buoyant knot]

making objects ride other objects can be hard as shit depending on the scenario

[swift crag]

well, without context, I can't answer that question

[buoyant knot]

MoveTowards is a vector operation

[swift crag]

all that MoveTowards does is produce a value between two points

[buoyant knot]

MoveTowards just helps you calculate a vector position. By itself, MoveTowards doesn’t actually move anything

[swift crag]

it does not intrinsically do anything

[twin bolt]

Should i just go the route of faking the elevator moving, using a courotine?

[swift crag]

if you use rb.MovePosition(pos), where pos was calculated via MoveTowards, that sounds fine

[twin bolt]

ok

[swift crag]

I see nothing fake about doing that

Especially since the elevator is kinematic

[buoyant knot]

yeah. just move it

kinematic RBs go to target position without asking questions

[swift crag]

you certainly wouldn't want to physically simulate how an elevator works lol

[twin bolt]

I mean, not moving the elevator at all, and opening the doors after a set amount of time.

[swift crag]

ah

that is also reasonable

Also a convenient place to put scene loads, if your scenes are big enough to require a load time

[buoyant knot]

i would only recommend that for a Luigi’s Mansion 3 elevator, where it is actually just a loading zone between levels

[twin bolt]

I'll just do that to resolve any issues, i might run into.

[hoary citrus]

That's not how real elevators work? 🤯

[buoyant knot]

elevators are an inside job

[twin bolt]

I know, which is why i wanted to do the real thing at first.

[hoary citrus]

[twin bolt]

What if, everything you aren't actively looking at isn't rendered, like in a game?'

What if everything behind you, doesnt exist, until you look?

[buoyant knot]

that’s a real thing

[twin bolt]

What if somebody that your playing online multiplayer(in real life) with is, looking at things you arent looking at. Does that mean that what they are seeing doesnt exist to you, or does your system, have to work harder to render everything?

[hoary citrus]

your system doesn't render what the other player is seeing if you're not seeing it also

[teal viper]

Rendering is always client side. You only need to render whatever your client needs to see.

[twin bolt]

i mean in real life though?

[static cedar]

Why are we considering real life?

[twin bolt]

Sometimes, it needs to happen.

[hoary citrus]

If a tree falls and nobody is there to hear it, does it make a sound?

[swift crag]

this is just solipsism in a trenchcoat

[twin bolt]

wait

[teal viper]

Wdym? Real life multiplayer? Are you asking about wether we live in a matrix or something? Lol

[swift crag]

check the profiler.

[twin bolt]

Yea

[teal viper]

Probably the wrong place to ask these questions then. And I don't think anyone knows the answer anyway.

[hoary citrus]

Is it developed in Unity? Does reality pay runtime fees?

[twin bolt]

Does a blind person, live lag-free, since nothing is actually being rendered, its just a whole bunch of audiosources?

[twin bolt]

Okay.

[teal viper]

Lag doesn't just affect rendering though. It affects sound and physics as well.

[pseudo frigate]

public void OnPointerClick(PointerEventData eventData)
{
    Vector2 localCursor = new Vector2(0, 0);

    if (RectTransformUtility.ScreenPointToLocalPointInRectangle(GetComponent<RawImage>().rectTransform, eventData.pressPosition, eventData.pressEventCamera, out localCursor))
    {
        Texture tex = GetComponent<RawImage>().texture;
        Rect r = GetComponent<RawImage>().rectTransform.rect;

        //Using the size of the texture and the local cursor, clamp the X,Y coords between 0 and width - height of texture
        float coordX = Mathf.Clamp(0, (((localCursor.x - r.x) * tex.width) / r.width), tex.width);
        float coordY = Mathf.Clamp(0, (((localCursor.y - r.y) * tex.height) / r.height), tex.height);

        //Convert coordX and coordY to % (0.0-1.0) with respect to texture width and height
        float recalcX = coordX / tex.width;
        float recalcY = coordY / tex.height;

        localCursor = new Vector2(recalcX, recalcY);

        CastMiniMapRayToWorld(localCursor);
    }
}

private void CastMiniMapRayToWorld(Vector2 localCursor)
{
    Ray miniMapRay = GameManager.Instance.minimapCam.ScreenPointToRay(new Vector2(localCursor.x * GameManager.Instance.minimapCam.pixelWidth, localCursor.y * GameManager.Instance.minimapCam.pixelHeight));

    RaycastHit miniMapHit;

    if (Physics.Raycast(miniMapRay, out miniMapHit, Mathf.Infinity))
    {
        //Debug.Log("miniMapHit: " + miniMapHit.collider.gameObject);
        GameManager.Instance.cam.transform.position = new Vector3(miniMapHit.collider.gameObject.transform.position.x, GameManager.Instance.cam.transform.position.y, miniMapHit.collider.gameObject.transform.position.z-4);
    }
}

im using this code with OnPointerClick so that when i click my minimap it's repositioning the player's camera. it works as i want it to but id like to make it so that when im holding the mouse button down over the minimap i could drag around and move the camera that way too.

what's the best way to go about doing that?

[teal viper]

Maybe IDragHandler🤔

[inner marsh]

    {
        if (Input.GetAxis("Vertical") > 0)
        {
        myT.position += myT.forward * movementSpeed * Time.deltaTime * Input.GetAxis("Vertical");
        }
        if (Input.GetAxis("Vertical") < 0)
        {
        myT.position += myT.forward * movementSpeed * Time.deltaTime * Input.GetAxis("Vertical") * 0.5;
        }    ``` so im making a thrust thing obv and when you go backwards its slower but the game doesnt like me putting * 0.5, any idea why?

[charred spoke]

[inner marsh]

alr ty

[pseudo frigate]

is it just a matter of putting the same code from OnPointerClick in OnDrag? i tried that and doesnt seem to be working

[timber tide]

OnDrag has a few different interfaces

[pseudo frigate]

i included drag start and end, but not sure if anything needs to be in them

[timber tide]

One thing to note is that only one event is triggered per frame

OnDragStart is a single event, but I think you can pretty much use onpointerclick too for it?

Not everything needs to be used, but OnDrag is pretty much the main event which should contain the repositional logic.

Ah, actually OnDragStart doesn't trigger until you hold down the mouse and move a bit

[pseudo frigate]

private PointerEventData _pointerData = null;

private void Update()
{
    if (_pointerData != null)
    {
        OnPointerClick(_pointerData);
    }
}

public void OnPointerDown(PointerEventData eventData)
{
    _pointerData = eventData;
}

public void OnPointerUp(PointerEventData eventData)
{
    _pointerData = null;
}

i tried this too but this doesnt work, curious how come that is

[timber tide]

Why doesn't the coordinate logic there work in OnDrag? I would assume it works similarly as OnPointerClick* would be called at your pointer position every frame instead of needing to click.

        Texture tex = GetComponent<RawImage>().texture;
        Rect r = GetComponent<RawImage>().rectTransform.rect;

This would be set at OnStartDrag probably

And then OnEndDrag you can probably ignore or unset everything being used

[nimble marlin]

Is it worth it trying to build a nice platformer player controller using RigidBody2D?

[timber tide]

If you want to use unity's physics system you go with rigidbody2D

otherwise you're implementing logic like gravity and stuff

[nimble marlin]

Yep, I am trying to build a nice player controller rn, but my player feels like he is falling through viscous liquid, increasing mass hinders movement on the x-axis, increasing gravity also has some similar affect.

[summer stump]

You're setting velocity then, right?

[nimble marlin]

yep

[summer stump]

What are you setting the Y value to?

You could also do AddForce if you'd rather btw,
Which is also Rigidbody based movement.

[nimble marlin]

experimenting between 700-800

[summer stump]

Wut...

[nimble marlin]

speed...

[summer stump]

Maybe show the code?
That is wild

Wait... are you multiplying it by deltaTime?

Because you should not be

[nimble marlin]

Going through docs seeing AddForce and velocity.

[nimble marlin]

haha

[summer stump]

Ok yeah... get rid of deltaTime

You'll have to reduce the speed a lot

And then, you are also setting the y value to 0 sometimes actually

[nimble marlin]

player just became Flash

[summer stump]

#💻┃code-beginner message

GetAxisRaw will return 0 when you aren't giving input. And 0 times your speed is obviously 0. So you are repeatedly setting velocity to 0 when in the air, which explains the "viscous fluid" feeling

You should do a ground check, and when not on the ground, set the velocity to a gravity value like -9.8

[nimble marlin]

righty got it, docs are a bit disorienting, figuring things out,thanks a lot for helping, I have used Raylib before which is very simple and everything that moves is multiplied by deltatime.

[summer stump]

Yeah, you want to use deltaTime in a lot of places, but deltaTime is ALREADY used in AddForce for multiple modes, and Velocity is in meters per second, so it already uses time.

But if you were using transform.position += someValue, you would want to scale that with deltaTime

Basically, unity does the work for you with AddForce and velocity haha

[nimble marlin]

yea, did that last time when making pong, collisions got fucked up and I had no idea why.

[summer stump]

Oh yeah, that bypasses physics and can cause that issue. It's basically It IS teleporting

[nimble marlin]

Again, tho, is it possible to make a good player controller using RigidBody2D?

I watched Tarodev's video on the topic and it really looks noice.

https://github.com/Matthew-J-Spencer/Ultimate-2D-Controller/blob/main/Scripts/PlayerController.cs

[cosmic dagger]

yes, you can . . .

[nimble marlin]

anything you can point me towards that achieves that besides documentation?

[cosmic dagger]

not that i recall. you need to determine how you're going to move: set velocity, add force, or the Move methods (kinematic rigidbody). each have their pros and cons. i'd look up videos, controllers, or references on those first . . .

[nimble marlin]

righty

trying to use Physics.SphereCastAll but in the editor it's telling me my starting pos needs to be a ray and in the documentation they have a whole bunch of parameters I have no idea what to do with. namely Direction. anyone know how to use this?

[teal viper]

There are several overloads for the method. One of them takes a ray. Some other take origin and direction. Choose one that suits your needs.

[delicate portal]

Hey I'm currently working on a house building system. How can I make sure that the buildable object will only be placed when its not clipped into the wall? And any solutions for the buildable incline issue while the cursor is on the wall?

[neon ivy]

I'm trying to use the pos one it just won't let me. guessing I need more variables but idk what they are nor what value of them I need

[copper pumice]

Since you already project the object into the scene just add a collider on the sides and check if touches something.

[teal viper]

What variables do you not know about?

[delicate portal]

It touch each other

[neon ivy]

it should be one of these

[copper pumice]

Use layers.

And make the layers not interact then.

[delicate portal]

Sure so if the wall touch the buildable, it shopuldnt be placed?

[teal viper]

They're all self explanatory. Which one do you have trouble understanding?

[neon ivy]

direction

[delicate portal]

Does this need an rb?

[copper pumice]

Yeah add a box collider with trigger enabled that is a bit larger than the object, and then if that collider is triggered make it not being able to be placed.

[teal viper]

Direction is the direction in which you want to cast your sphere.

[neon ivy]

like, no idea what direction it wants. why does it even need a direction

do I just say vector3.left?

[teal viper]

What direction do you want?

[copper pumice]

And then make it so that the collider for checking only interacts with the correct objects.

[neon ivy]

no idea xD

[delicate portal]

With what function? OnTrigger?

[neon ivy]

I don't care about the direction

[teal viper]

If you have no idea, then why even do the cast?

[neon ivy]

I just need to get all objects in the sphere

[silent obsidian]

Hello guys. How can I get the same behaviour as in "GetAxis("Horizontal")" with the new input system?

I don't want it to jump instantly from 0 to 1 and -1 but rather to go smoothly.

[copper pumice]

Yeah OnTrigger put a boolean to true and OnTriggerExit put it to false.

[teal viper]

Then you're using a wrong method.
Use OverlapSphere instead.

[copper pumice]

And then something like: if (isTouchingWall) return;

[neon ivy]

ah

[timber tide]

sphere cast goes in a direction

[teal viper]

Sphere cast is like rolling a ball in a direction.

[neon ivy]

oooh

[silent obsidian]

This is the current setup

[neon ivy]

that explains why I was confused. thanks

I thought a spherecast was just a spherical raycast

[silent obsidian]

@copper pumice I want to recreate the behaviour that "GetAxis" has but with the use of the new input system.

[timber tide]

it's more related to the standard raycast while overlap sphere is for a general area

[queen adder]

Today I found out that there was actually a hack for this. Just click on any object in the heirarchy, then spam Alt+Left arrow

[delicate portal]

Sorry, so each of the walls should have the scipt? or the buildable should be a trigger?

[delicate portal]

I've done this

[teal viper]

It is. What you're referring to is not a spherical ray cast, since it doesn't cast anything anywhere. You just want to check if anything is overlapping a sphere.

[delicate portal]

and it doesnt work

[neon ivy]

so I'm not fully understanding casts in general

[queen adder]

use GetMask

also check if the code even work without the if check

[teal viper]

A raycast is like moving a point through space. You "cast a ray". A sphere cast is like moving a sphere through space, thus sphere cast.

[queen adder]

actually idk if getmask will work too

[neon ivy]

so it's just a raycast with thickness?

[teal viper]

With a radius, yes.

[neon ivy]

knowledge has been obtained, thanks

[copper pumice]

It should be given to the gameobject with the collider

And I actually meant to change it so that the layers only interact with each other in settings, not with an if statement. But that should probably work too. Check the layer spelling and make sure that the correct objects has the layer enabled. You can always try tags instead.

[delicate portal]

I did it with oncollisionstay, now it works

[copper pumice]

Hmm alright

Well if it works it works.

[delicate portal]

what do you mean?

[copper pumice]

You can change it so that only certain layers collide with other layers in the physics settings

[delicate portal]

I know that

[solid yew]

Hey, I'm trying to set a single component of an object's rotation without changing the other components. I don't want to change the rotation incrementally (i.e. with RotateAround), I want to directly set the value.

I've been trying this:

    void SetRotation(float angle)
    {
        transform.localRotation = Quaternion.Euler(angle, transform.localEulerAngles.y, transform.localEulerAngles.z);
    }```
but I'm getting some strange behaviour when `angle` is greater than 90 degrees (the angle flickers between being greater than 90 and less than 90). I've read that reading from `transform.localEulerAngles` is a bad idea, but I haven't been able to find an alternative solution. Does anyone have a better way to do this?

[frosty hound]

If you hold shift while doing the alt arrow command, it'll open and close all. It also works in the project tab as well.

[queen adder]

for some reason, holding shift prevents me from closing anything else than what gameobject is selected

[frosty hound]

Maybe it's just shift and no alt. Im not here to test it. I use it all the time but it's second nature that it's just muscle memory.

[north kiln]

Iirc it's just alt, not shift at all

[queen adder]

actually, the alt or shift isnt even important

holding left arrow can do it alone

[frosty hound]

It is now because I'm confused and need to know what I've been doing. But that's hours away from checking. Lol

[queen adder]

yea, left arrow can do it alone, alt speeds it up

[dusk minnow]

Is there a way to tracj which objects are enabled and disabled in a parent and save this?

[lone sable]

Anyone have any resources they could point me twoards, to editing a sprite shape via runtime? I know I could grab each spline point, and have a handle the player could move, however, adding new points is I'm not sure?

[teal viper]

Sure. Loop the children and cache their state in a bool list or something.

[dusk minnow]

ah, yeah that should do it. Thank ya 🙂

[queen adder]

How can I fix this error. WARNING:We recommend using a newer Android Gradle plugin to use compileSdk = 33

[keen dew]

It's a warning, not an error

[queen adder]

No it's an error.

[keen dew]

No, it's a warning. Those errors are caused by something else. Post the full error message to #📱┃mobile

[fringe pollen]

Just to make sure, if I for example do otherScript.someArray = this.someArray; and then do this.someArray[0] = 7;, then otherScript.someArray[0] == 7; right?

[slender nymph]

yes, arrays are reference types. so if both variables reference the same array instance then modifying the elements of one of those variables will affect the array referenced in both variables.
however you cannot assign a new array instance to one variable and expect the other to be affected

[fringe pollen]

Alright, thanks!

[swift crag]

Assigning to a variable will only affect another variable if your variable is a ref

well, or out, I guess

[forest wolf]

Hey Loha, there is a small angle transformation you need to do in order to make it work. I don't know what you trying to achieve but when working with euler angles very often you have to do something like eulerDir.x -= eulerDir.x > 180 ? 360 : 0; .

[swift crag]

Directly manipulating individual euler angles can be difficult.

as you mentioned

[forest wolf]

However alternative way, which I use more often is not working directly with euler angles but rather setting the transform.foward to the right direction. Basically you find a direction to the target by doing (targetPosition - originPosition).normalized and then set it to e.g. transform.forward

[swift crag]

Yeah. That can often behave better.

[somber wren]

hello guys ! hello can i force a moving gameObject to stay at a certain distance of the ground ?

[fossil drum]

Not much information in your question to be honest. You could do it many ways, just giving it a collider would be one of the easier ones.

[somber wren]

without physics* sorry

like i have a 3d object that can climb on walls (its a spider)

but i want it to stay always at the same distance of its ground

[buoyant knot]

is it dynamic or kinematic?

[somber wren]

kinematic i guess ?

it has no rb no collider

[buoyant knot]

uh… it has no collision at all?

[somber wren]

yes

only with raycasts and all

[buoyant knot]

ok, then you’re going to need to raycast or spherecast to move around

[somber wren]

its already moving and climbing walls

[buoyant knot]

it would maybe be easier to give it a kinematic rigidbody and set its layer to ignore raycasts

[somber wren]

i just want it to stay a certain height of the ground

i could put a collider without a rb tho idk, my professor doesnt want physics in the project

[buoyant knot]

that way nothing can interact with it, but the physics system can smoothly move it from point a to point B

[somber wren]

its already moving hello u read what i write 😭😭

its already moving and climbing walls
i just want it to stay a certain height of the ground
i could put a collider without a rb tho idk, my professor doesnt want physics in the project

To sum it up

[buoyant knot]

what I mean is if it has a Kinematic RB, you can tell it to MovePosition once per physics frame

and the physics system will figure out where to put it in between for every frame

makes sense?

[somber wren]

it does

but doesnt solve anything, ive already been through that

gravity fucks up the whole thing

[buoyant knot]

gravity has no effect on kinematic RBs

[somber wren]

if i put gravity, it cant work, if i remove it, it doesnt work too

oh yeah

kinematics one mb

but a rb would just make my spider fly

[buoyant knot]

does the spider climb walls?

[somber wren]

loup

im gonna throw my computer off my window

[buoyant knot]

like vertical walls

or just like slopes

and ceilings

[somber wren]

it walks on everything

[forest wolf]

Hmmm, silly question but cannot you simply raycast downwards and check the distance between spider's position and the hit position?

[somber wren]

for the 4th time,

[buoyant knot]

that means he needs to define down

[somber wren]

-transform.up

[buoyant knot]

he needs to initialize to a certain snapping direction

[forest wolf]

exactly

[somber wren]

i can, but i cant say "trasnform.pos = upRay(8) from this hit pos)

bc it wouldnt move

[buoyant knot]

then spherecast to look around

yeah, I think the pieces all make sense now

so what is the part you have trouble with?

[forest wolf]

you can, your movement would have to only prevent movement in the down direction then

[somber wren]

wait

im gonna picture you bc

[buoyant knot]

when you say it can walk walls but not maintain distance, you mean you can’t get it to keep distance, but it does respect level geometry shape?

or that it does not respect level geometry shape, so if you have a hill, it moves along a plane?

[somber wren]

here my spider climbing a cube

and going down on the other side

he is my problem, wrong distance of the ground

[somber wren]

yes

[buoyant knot]

oh it’s a tetrapod

ok, so right now you use a cast to know where it needs to go, right?

[somber wren]

yes its the red rays

[buoyant knot]

that cast outputs a RayCastHit, which has a normal for the surface

[somber wren]

yes

and then pouf spider.normal = hit.normal

with a lerp, and more of a rotation but yeah

[buoyant knot]

if you need to translate normal to the surface, then just transform.translate by hit.normal * the distance you need

[forest wolf]

I think I still struggle a little bit to understand the issue. Do you want to keep the body certain distance from the surface it is walking on or never be able to reach the ground (the blue surface)?

[buoyant knot]

i dont understand which part is confusing

that’s a good question

because that would be an inverse kinematics problem

[forest wolf]

Can you sent also 2 pictures: one of what is going on (the problem) and the other (in the editor, not in the play mode) how you would like it to look like?

[somber wren]

first proposition

body certain distance from surface

maybe its just a translate to do

thats why im in code beginner xd

[buoyant knot]

oh shit that is hard

given that it is a tetrapod

[forest wolf]

In that case I believe the simplest way would be to do as you say simple translate. You could simply do transform.position = targetPosition + (transform.up * distance)

[buoyant knot]

actually maybe not so hard, if you solve the body first

not hard if you are okay with it looking janky lol

[buoyant knot]

use this with casting to move around the body. Then the hard part is solving the positions of the legs as it walks

[somber wren]

whats hard

[buoyant knot]

yeah, this is a hard problem if you want it to be accurate

because it isn’t a simple object

it’s a tetrapod

[somber wren]

it is

[buoyant knot]

the four legs move with the body

[somber wren]

the legs follow the body, i just need to touch to the body

the controller moves my body and the legs follow by themselves, procedurally animated

[buoyant knot]

so if you want it to be accurate, you need to solve the motion of the whole thing like a robot

[somber wren]

i've that rn

i just want it

to be at a the right distance of the surface its walking on, thats all

[buoyant knot]

making the body level is easy

that is the super easy part

[somber wren]

then i just need that

[buoyant knot]

making the legs match up to accurately move everything in a way that makes sense is the hard part

[somber wren]

ITS ALREADY DONE 😭

[buoyant knot]

so yeah, just use some spherecasts, bro
