[wintry quarry]

A float would be just fine if you need to just store one value

[vale karma]

bc i needed it to make a quaternion 😮

im sure there are plenty more things in there that arent even needed, ill get to them soon

[wintry quarry]

Quaternion.Euler(0, yRotation, 0)

[vale karma]

yea i guess your right haha, i think i did that bc last time i got in a kerfuffle for doing math inside a MoveRotate() method with a quaternion

its not related but i miss on my part

[viral tulip]

so my intellisense stopped working, how do I get it back?

[broken drift]

does anyone know why my "if (Input.GetKeyDown(KeyCode.Space))" inside "playersCombat()" method only works once?

[teal viper]

Is the object getting disabled/deactivated perhaps?

[broken drift]

i dont know but i didnt put any condition to disable it yet.
this in the entire code:
`using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class playerCombat : MonoBehaviour
{
[SerializeField] bunnyStatScripts _bunnyStats;
[SerializeField] GameObject _gameOverScene;
[SerializeField] int _damage;
int _newHealth;

void takeDamage()
{
    int _newHP = _bunnyStats._health - _damage;
    _newHealth = _newHP;
   
    if (_newHP == 0)
    {
        _gameOverScene.SetActive(true);
    }

}

void playersCombat()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        takeDamage();
        Debug.Log("you pressed space");
        Debug.Log("HP: " + _newHealth);
    }
}

void Start()
{
    _gameOverScene.SetActive(false);
    Debug.Log("HP: " + _bunnyStats._health);
}

void Update()
{
    playersCombat();       
}

}`

[gaunt ice]

check if the method is running

[broken drift]

which method? playersCombat()? if so, then it runs but only once

[gaunt ice]

yes, or update, since your update will call that method

you can log in ondisable to find out the one that disables your object

[teal viper]

Wdym "I don't know". Can you not pause the game and look in the hierarchy/inspector???

[broken drift]

i tried what u said and paused after pressing space and the object where the script is, is still active but pressing space again does nothing anymore

[broken drift]

ondisable?

[gaunt ice]

are there any error

[broken drift]

no errors

just nothing happens anymore after pressing space once

[gaunt ice]

void Update(){
  log i am called
}

or use debugger to check if it is called

[broken drift]

i used debug.log and yea it only shows once

[gaunt ice]

public void method(){
  if(some condition){
    log
  }
}
```is completely different from
```cs
public void method(){
  log
  if(some condition){
  }
}
```the above one is not the way that verify the method is running

btw i guess there are errors

[vale karma]

does basic movement go in a state machine or in a regular class on its own?

[teal viper]

Can you take a screenshot of the whole console window?

[teal viper]

Not quite sure what you're asking. What state machine are you referring to?

[vale karma]

im probably too inexperienced to even describe it, but im trying to break my movement up into states so I dont get spegeti code like i did last time. The catch is i have it set up but dont know exactly how to actually code the movement in there. Im sure i just need to watch a few more vids and be patient

[vale karma]

how do you code rigidbody movement in a stamemachine? theres no fixedupdate to use

[broken drift]

i did what u said and this is what showed on the console now

[broken drift]

sure

[keen dew]

Pressing space works just fine. You have Collapse on in the console so you see each log only once.

The problem is that you never change _bunnyStats._health

[teal viper]

Again, what do you refer to by "state machine"?
State machine is a programming pattern there are millions of ways to implement one,but most of them have some for of state update, so your question doesn't make sense.

[vale karma]

im following this tutorial https://www.youtube.com/watch?v=Vt8aZDPzRjI

https://paste.ofcode.org/kFbVuaYDukLS6BUyDbxjch

[teal viper]

1. You're free to update the states in whatever update you want.
2. You're not limited to only one update. You can implement both a regular and a fixed update in the states.
3. You don't have to move the character from within the states, they could just be setting some important variables, like movement speed for them to be used in the actual character movement logic.

[vale karma]

so your saying I could run private void FixedUpdate() { } in the EnterState and it will continue running while its in that state?

[teal viper]

If you call it from a MonoBehaviour, sure.

In which case it would have to be public

[vale karma]

thats weird, but useful

[teal viper]

Why is it weird?

[vale karma]

ill try with making a movement script and changing the values in the states

[broken drift]

tysm yea it works fine now

[vale karma]

and calling FixedUpdate on EnterState, Idk, just being new to it FixedUpdate and Update are intimidating to use correctly

[teal viper]

They're just methods called by unity regularly. There's nothing special about them

[vale karma]

wait hold up, if i am correct, void Update() { currentState.UpdateState(this); } basically means it uses the code in that method in the StateManager Scripts Update function, so you wouldnt have to write an update fuction inside the state manager, you could just write ```void FixedUpdate()
{
currentState.UpdateState(this);
}

im not going to write my movement code in there, bc it will only make my code redundant, but just a thought

[teal viper]

Assuming, you keep both, you'll get state update called on both updates, likely messing up the logic in it.

[vale karma]

no just having it in the managing script

it is challenging to break up this code correctly

[zinc osprey]

Not sure if this is the right chat for this, but I can't find anything more appropriate. Can I make the red image render on top of the other item slots?

[teal viper]

Next time if you don't know where to ask, use #💻┃unity-talk

Move the image object below the item slots in the hierarchy

[zinc osprey]

I need it to be a child of one of the slots.

[teal viper]

Can't do that 🤷‍♂️
Will have to rethink whatever it is your doing.

[zinc osprey]

Damn.. ok thanks.

[tawdry rock]

Can someone explain to me if i write public float someFloat = 5.0f; and save it then i change the value to 2.0f and save why unity still thinks my float is 5?

[ivory bobcat]

You're probably looking at the wrong instance

[tawdry rock]

it's like once it declared it's set to stone and i only can change in editor not via script

[keen dew]

because that's the default value, the actual value comes from the inspector

If you don't want the inspector to set the value then don't make it public

[tawdry rock]

but isnt the inspector value should update according to script?

[ivory bobcat]

What makes you think it's not changing?

Show the log

[keen dew]

no

[tawdry rock]

because i can see its not updatin in the editor. same with bools once i say in script bool = false then i delete the false part (by defaut bool are true), it still false in the editor.

[ivory bobcat]

Likely you're referring to a different instance

Show where you've changed it in code

And log the value after

[queen adder]

can someone help me with my web swinging movement codee please?

[arctic ibex]

Quick question, I'm well aware this can't possibly be the correct way to do this, but I'm not sure what the correct way is (I'm checking if the camera is within a set box, marked out by the corners) (Corners 1 & 2 are Vector 3s) (It's a 2D game) (This little overcomplicated if statement doesn't work anyway) (I think I'm addicted to brakets)

lol forgot to attach the screenshot

[languid spire]

you can create a Bounds and then use the Contains method

[fierce shuttle]

If you have a specific question, im sure someone may be able to help if they know a solution - what have you tried so far, and what is the result your trying to achieve?

[arctic ibex]

... so how do I do that? "public bound box;"

[languid spire]

https://docs.unity3d.com/ScriptReference/Bounds.html

[queen adder]

locking onto objects and being able to swing from them. but i have got that working but i keep swinging from the first place i shoot even when i am not holding my trigger button down

[arctic ibex]

👍 thanks!

[ivory bobcat]

Cool feature

[tawdry rock]

i have a 2 slider mouse X and Y sensivity. on valuew change i save it to player prefs: PlayerPrefs.SetFloat("mouseX", mouseX.value); and i load it with mouseX.value = PlayerPrefs.GetFloat("mouseX", 2.0f);. this works fine, even if i change scene still work. but for my mouseY it's working in the main menu (it loads the default 2.0f) but i can't load it in the game(after scene change).

[ivory bobcat]

What do you mean by not being able to load it?

Did you save the player prefs?

[fierce shuttle]

So your issue is that your swing logic is happening all the time instead of only when you press the relevant input? What does your !code look like?

i mean the value changing to 0 even if i save it after change and load it on awake

[gilded elm]

hii, when I assemble objects together (in VR) and I take the parent object, and I move the object in all directions, the objects which are assembled on it slide a little, it floats and I want to know if it is possible which remains fixed and no longer moves at all as if it were a single object ?

[ivory bobcat]

So you've called the save function from player pref?

[tawdry rock]

but in the main menu always loads the correct sat value

[ivory bobcat]

Else you'll be working with a local copy that'll not update the file till after the application closes

[tawdry rock]

i use the slider on value change thingy to call a save function which should save the value of the mouseY. same thing as i showed with the mouseX but with Y

[ivory bobcat]

So you called the player pref save function?

[tawdry rock]

im pretty sure but let me debug the heck out of it.

[ivory bobcat]

https://docs.unity3d.com/ScriptReference/PlayerPrefs.Save.html

It's either you've called it or not, simple as that.

[tawdry rock]

where does this go?

[ivory bobcat]

You'd probably want to have it called before the scene has changed

[fierce shuttle]

Havnt worked with VR, though sounds like your child objects might have rigidbodies and colliders, if you dont want them to respond to physics, you can disable their colliders and freeze the constraints on the rigidbodies or remove their rigidbodies as well

[gilded elm]

I need physics and their collisions

[fierce shuttle]

If you have physics, things will slide and react to collision objects, alternatively then you could either freeze the constraints, increase the drag, set to "is kinematic" or force the position and rotation by code

[tawdry rock]

i guess i solved it by a noob mistake im too shy to admit. however thank you for your time trying to help me.

[vague dirge]

Hi, quick question, if I want to have a 1st person camera and a 3rd person camera on input, is it better to have 2 cameras and switching between them or changing all of one camera values ?

[gilded elm]

if I slip the constraints I will not be able to take the object in my hand and assemble it myself

[tawdry rock]

having 1 camera is better imo, especially when you apply post processing so they don't override each other

[fierce geode]

Are there any tips for trying to do a camera-based third person character that moves respective to the normal of the ground?

Like I feel like I'm missing some key component; like if upside down and you still want them to move forward, but that's technically upside down.

[fierce shuttle]

You could freeze it after youve assembled it, and unfreeze it when you need to move it again, or you could try some of the other suggestions and see if they help

[twin ibex]

I have dumb peoblem

[gilded elm]

do you know how to freeze the object once assembled and remove the gel once it is recovered?

[fierce shuttle]

Thats what freeze constraints does, it prevents a rigidbody from moving due to physics on specific axies, so you can toggle the axies you want to allow or disallow movement on as needed

[hybrid sundial]

I’ve programmed before and I decided to get back at it it using unity.learn and I realised that in the course the code is very well badly coded, it uses tons of unnecessary public variables and weird forms of writing simple code?

[fierce geode]

Does transform.rotation = (grounded) ? Quaternion.LookRotation(transform.forward, ground_normal) : Quaternion.identity; look bad? Trying to make my character constant stand upwards following the ground normal, and while it works with slopes going towards the X axis, but fails to rotate correctly with slopes going on the Z axis

Nevermind, played aroudn a bit and transform.rotation = (grounded) ? Quaternion.FromToRotation(Vector3.up, ground_normal) : Quaternion.identity; did the trick

[hard hornet]

you dont need the brackets around grounded btw

[buoyant knot]

if your character’s collider moves at all upon rotation, this will not work

[gilded elm]

I'm trying to look for lines of code to freeze the positions when I place the object and unfreeze when I take it but I can't find it

[fierce shuttle]

Heres the docs for how to use rigidbody constraints: https://docs.unity3d.com/ScriptReference/Rigidbody-constraints.html

[frigid sequoia]

I have noticed that while at full screen in Game mode (but doesn't need to be actually running so is not script related), if I tab, the interface moves slighty, like it is resizing even though the screen size is not changing at all; I can not be sure of what's actually happening cause it only happens at full screen and I cannot check the inspector casue as soon as I exit full screen it resets back; is this normal? Is something wrong in my interface setup or what?

[keen dew]

If you know it's not script related then don't post to a code channel. If you mean the game's interface then post a video or screenshots to #📲┃ui-ux

[frigid sequoia]

Oh, you are rigth, there is a specific chanel for that, I though this was more of how the canvas is coded thing, sry

[river bear]

What should I do to make game like need for speed

What I should learn?

[keen dew]

C# and Unity

[gilded elm]

It freezes the position when it is not on the slot but I still have the problem :/

[rare basin]

probably cars aswell and driving logics

[fierce shuttle]

If the constaints are frozen and it still slides, then its possible something else is the problem, could you maybe record a video showing the issue and your rigidbody settings?

[gilded elm]

yes

[amber spruce]

hey so im currently working on a save and load sysetm using jsons i have ran into the problem of how do i save like the actual scene in it because for example i have enemy spawners placed throughout the scene and when you go past a certain area they spawn a few enemies how do i save those spawned enemies???

[hallow gate]

guys the guy in the tutorial is trying to teach me how to make collisions and he says i need layers, when he goes to the layer section there already are 2 layers assigned but for me there arent. how can i assign them to my player and to the background? here are the pics of reference:

left pic is his right one is mine

[rare basin]

you can't "save" entire scene

save what data you exactly want

enemies positions

enemies health etc

[amber spruce]

if i save the gameobject can i then use that to instantiate it since its a prefab or do i need to drag the prefab from the editor

[earnest atlas]

If you drag it from editor you will use that exact object. IF you drag it out of prefab folder it will make new one.

If you just want to spawn you should use the one in Prefab folder.

[fierce shuttle]

Doesnt look like you have any constraints frozen here, alternatively you could try toggling "is kinematic"

[hallow gate]

nvm i figured it out

[gilded elm]

I found a solution I set its parameters to the maximum

[earnest atlas]

When making weapons why should I use raycast to check for hits instead of generting a bullet?

Considered raycast is pretty much instant

[autumn tusk]

i dont understand the addforce function at all

https://docs.unity3d.com/ScriptReference/Rigidbody2D.AddForce.html im reading this rn

[polar acorn]

It adds a force to the rigidbody. The force modes might be a bit confusing but this infographic should help clear that up

[autumn tusk]

basically i want to add a force leading from the direction the player's gun is firing in

recoil as a jumping mechanic basically

{
    [SerializeField] AudioClip ShotgunClip;
    [SerializeField] AudioSource audioSource;
    public Rigidbody2D playerbody;
    public Transform transform;
    [SerializeField] private float thrust = 832998f;
    Vector2 launchcalculation;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetButtonDown("Fire1"))
        {
            PlayerShoot();
        }
        // Vector2 rotationshit = transform.rotation;
        print(transform.rotation.eulerAngles.z);
        launchcalculation = (transform.rotation.eulerAngles.z,thrust);

        //transform.rotation.eulerAngles
    }

    void PlayerShoot()
    {
        audioSource.PlayOneShot(ShotgunClip);
        playerbody.AddForce(transform.position * thrust, ForceMode2D.Impulse);
        print("player shoot");
    }
}

launchcalculation refuses to take eulerangles.z as a parameter

[polar acorn]

Why are you using a position as a direction

[autumn tusk]

refuses to take rotation as a parameter

as rotation is a quaternion

[polar acorn]

Why are you trying to store a tuple into a variable of type Vector2

Honestly what is even the point of launchcalculation, you never use it

[split dragon]

Hi. I tried to find the difference between 2 types of security modifiers: "Empty" and "Private". I know that private can only be used in the same script, but it's the same with an empty one. Is there a difference and what is it? On the Internet, as usual, they talk about everything except this.

[polar acorn]

When no access modifier is provided, private is assumed

[dry ravine]

Whenever I try and click the button underneath the text it dosen't work because the text has a hitbox, is there a fix?

[split dragon]

Oh, I get it. Thanks

[dry ravine]

Prolly should've posed in UI but whatevs

[polar acorn]

Disable Raycast target on the text

[dry ravine]

Thanks

I appreciate it dude

[rare basin]

weird question

it's 2 different approach

it depends on your game design

if you want raycast hits (hit-scans), or projectile-based hits

lasers (hitscan), arrows (projectile based)

[earnest atlas]

I noticed that at high speeds triggers happen to fail

[rare basin]

if you are moving throught modifying the transfomr position directly then it might happen

need physics for proper collisio ndetetion

and different collision detection mode for fast objects, like Continous

[hybrid sundial]

I’m using Input.GetAxis but I want it to only work when I press w and when I press x it does nothing

[autumn tusk]

i dont understand why my script isnt adding force to another rigidbody2d

basically with the script i have rn i want to make it so that it adds the force to the player character

[polar acorn]

Show code

[autumn tusk]

just experimenting with adding forces for now, have this rn

using System.Collections.Generic;
using UnityEditor.Experimental.GraphView;
using UnityEngine;

public class Player : MonoBehaviour
{
    [SerializeField] AudioClip ShotgunClip;
    [SerializeField] AudioSource audioSource;
    public Rigidbody2D playerbody;
    public Transform transform;
    public Transform crosshairpos;
    [SerializeField]  float thrust = 1f;
    Vector2 knockback;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetButtonDown("Fire1"))
        {
            PlayerShoot();
        }
        // Vector2 rotationshit = transform.rotation;
        print(transform.rotation.eulerAngles.z);
        // launchcalculation = (transform.rotation.eulerAngles.z,thrust);

        //transform.rotation.eulerAngles
        Vector2 direction = crosshairpos.position;
        Vector2 knockback = direction * thrust;
        print(direction);
        print(knockback);
    }

    void PlayerShoot()
    {
        audioSource.PlayOneShot(ShotgunClip);
        //playerbody.AddForce(transform.rotation * thrust, ForceMode2D.Impulse);
        playerbody.AddForce(transform.up, ForceMode2D.Impulse);
        //print("player shoot");
    }
}

this works fine when i add a rigidbody to the shotgun object

but doesnt work on the player character for some reason

[polar acorn]

Does your player character set their velocity to a fixed value at any point

[autumn tusk]

this has nothing to do with mass and gravity scale

[autumn tusk]

just using a basic getaxisraw

[hallow gate]

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

public class Playerr : MonoBehaviour
{
    public float moveSpeed;

    public bool isMoving;

    private Vector2 input; 


    private Animator animator;

        animator = GetComponent<Animator>();
    }
    
    private void Update()
    {
        if (!isMoving)
        {
            input.x = Input.GetAxisRaw("Horizontal");
            input.y = Input.GetAxisRaw("Vertical");
            Debug.Log("This is input.x" + input.x);
            Debug.Log("This is input.y" + input.y);


            if (input.x != 0) input.y = 0;

            if (input != Vector2.zero)
            {   

                animator.SetFloat("moveX", input.x);
                animator.SetFloat("moveY", input.y);



                var targetPos = transform.position;
                targetPos.x += input.x;
                targetPos.y += input.y;

                if (IsWalkable(targetPos));
                StartCoroutine(Move(targetPos));
            }
        }

        animator.SetBool("isMoving", isMoving);
    }
    
    IEnumerator Move(Vector3 targetPos)
    {
        isMoving = true;
        
        while ((targetPos - transform.position).sqrMagnitude > Mathf.Epsilon)
        {
            transform.position = Vector3.MoveTowards(transform.position, targetPos, moveSpeed * Time.deltaTime);
            yield return null;

        }

        return true;
    }
}
``` idk what i did wrong but for some reason my code wont make me collide as intended even tho i did as the tut said

this the vid https://youtu.be/dbMm2_M3Wfc?si=SrZSqoJapYnSq390

[polar acorn]

So you're teleporting the character every frame without regard to the forces currently acting on it. Your addforce is working, but any movement it confers is overwritten by a teleport to a specific spot

[autumn tusk]

alright

should i just use an addforce for the player movement?

[buoyant knot]

if your player is a dynamic RB, then yes

if your player is anything else, then no

dynamic RB is always at the mercy of the physics engine. Kinematic RB only goes where you tell it to. I recommend you choose carefully.

[autumn tusk]

hmm, ill which works best

might use velocity instead

[buoyant knot]

Kinematic RBs work by MovePosition. Dynamic RBs work by AddForce and velocity

[hallow gate]

@polar acorn help me out lil bro

[summer stump]

Just fyi #📖┃code-of-conduct

[summer stump]

Looks like your player has no collider or rigidbody

Wait, your player is a UI element? Interesting

[hallow gate]

so look, the tut didnt say nun about that but i still made it work using the tut and chatgpt but there is one issue. whenever i collide with something the distance between me and that "solid object" is too great

[hallow gate]

i just did as the tutorial says man i have no idea if its right or not

[hallow gate]

the distance of collision is too big is what im trying to say

[spiral narwhal]

I remember there being a better practise than abusing recursion, what was it again?

private IEnumerator IncrementAge()
        {
            _age++;

            if (_age > EXPECTED_LIFE_TIME)
            {
                Die();
            }
            else
            {
                yield return new WaitForSeconds(10);
                StartCoroutine(IncrementAge());
            }
        }

[summer stump]

Just loop? If the age is overlifetime die and break
If not, continue looping

Recursion can be fine, but in this case, you are creating a new IEnumerator each time

[spiral narwhal]

Can you give an example

[summer stump]

I'm not sure which part needs an example

while
if age to big
Die
Break
else
Wait
Yield null

Might not need that yield null actually

[gaunt ice]

no need to yield return null

either break or wait for 10 seconds

[summer stump]

The while condition could also be the age
while age

[summer stump]

Yeah, that's what I thought

[spiral narwhal]

        private IEnumerator IncrementAge()
        {
            _age++;

            while (_age <= EXPECTED_LIFE_TIME)
            {
                yield return new WaitForSeconds(10);
                StartCoroutine(IncrementAge());
            }
            
            Die();
        }

So something like this?

[summer stump]

No, the age increment needs to be inside the loop. And get rid of the start coroutine

The whole point is to remove the start coroutine

[spiral narwhal]

Ah yeah right

        private IEnumerator IncrementAge()
        {
            while (_age <= EXPECTED_LIFE_TIME)
            {
                _age++;
                yield return new WaitForSeconds(10);
            }
            
            Die();
        }

[hallow gate]

can someone help me with fixing my collision issue? my character to solidObject collision works but for some reason the distance between them is bigger than intended

[wintry quarry]

look at the collider gizmos

[hallow gate]

what is that and where is that

[buoyant knot]

i would not store an age variable tbh

[wintry quarry]

the green outline of your collider in scene view

[buoyant knot]

I would store a timestamp for birth, have a property to interpret age, and a single coroutine to call Die() after a single wait call

[hallow gate]

everything is right with that. thats the problem the collision distance is greater than the outlines

[spiral narwhal]

No it's not an actual age, it's more of a game design choice

[wintry quarry]

by how much? There's a "default contact offset" setting in physics settings which is like an additional buffer

[polar acorn]

How are you determining "collision distance"

What value is it and what are you expecting

[hallow gate]

can i somehow show u in vc by sharing screen because my explanations are pretty bad

[hallow gate]

same goes for u "

[buoyant knot]

do you need to know about accurate collision distances?

[polar acorn]

no

[buoyant knot]

are you using Physics2D?

[buoyant knot]

ok, i can explain a bit then

[hallow gate]

ok

[buoyant knot]

Physics2D uses Box2D. For math reasons, all edge and polygon shapes have a radius tied to them for collision purposes.

This includes basically all Collider2D except circle colliders (and maybe capsule colliders?)

The default edge radius is something like 10^-4

If you get the “distance” between two colliders, this radius gets added in (depending on the type of query).

So if you get the distance between two Circles that are 1 appart, unity says distance =1. If It’s between two box colliders 1 appart, unity will say something like 0.998

This becomes relevant when you try to put two things into contact, and so the distance between them is very sensitive to that edge radius. The default edge radius is based on default contact offset, which is a setting in Physics2D project settings, and if you ever change this value, then everything will break.

@hallow gate

btw this affects the results of a LOT of Physics2D queries, like Collider2D.Cast, and Collider2D.Distance

that seems mad complicated for some reason i just followed the tutorialist and he didnt show me any of that he just showed me code and that was pretty much it

[buoyant knot]

how relevant it is depends on what you are doing

if you need to move something to a precise location to be right in contact with something else, it becomes relevant. Or if you are trying to do something specific with the distance between two things in contact, it is relevant

[polar talon]

Hi all, has anyone had issues with reloading the current scene a player is in?

I have a scene that instantiates a lot of procedurally generated content and deletes some other content. When I use SceneManager.LoadSceneAsync I'm expecting the scene to revert to it's original state, but the content I generated or deleted previously does not reset.

[polar acorn]

Async scene loading is inherently additive scene loading. Do you explicitly switch to the new scene when it's done loading or just let it pop in? Do you have any objects in a DontDestroyOnLoad object? Those ones will persist whether you're using additive loading or not

Yes, code would be nice to see how you're handling the scene transition. A before and after screenshot of the hierarchy would be nice too

[polar talon]

I'm using LoadSceneMode.Single, I do have some objects with DontDestroyOnLoad but I don't need those to be reloaded

Thanks for the reply, I'll get the code and hierarchy examples

[deep quarry]

        groundedCheckDistance = GetComponent<MeshCollider>().sharedMesh.bounds.size.y / 2;

I am getting following error for this line of code:
NullReferenceException: Object reference not set to an instance of an object

[languid spire]

so there is no MeshCollider on the object

[swift crag]

a null reference exception has one, and only one, cause: you attempted to access a member from null

[languid spire]

that proves nothing

[swift crag]

that's not the only thing that can be null (:

[deep quarry]

There is a MehCollider to the object ^^

[swift crag]

notably...

[swift crag]

We could still be looking at the wrong object.

another object could have a RocketController but no MeshCollider, after all

You can find out exactly which object is responsible for many kinds of errors by clicking once on the error message in the console

it'll take you to the offending object in the hierarchy or project window

[languid spire]

we do not even know this is RocketController

[deep quarry]

How do I add a Mesh to it?

[languid spire]

first post the stack trace for the error

[swift crag]

this code is probably wrong, especially if anything has been scaled or rotated.

[deep quarry]

Yea, I've scaled up the "Rocket", in which the RocketController is onto

[swift crag]

for multiple reasons:

• A MeshCollider must be given a mesh asset. If you have a MeshRenderer parented to whatever this object is, then you'd have to make sure you assigned the same mesh asset
• You're checking the bounds of the mesh asset itself. This is not the bounds of the collider.

[languid spire]

not gonna generate a NRE

[swift crag]

yes, but I think the design is wrong even after fixing the NRE

sharedMesh is null so it's throwing up

[languid spire]

indeed

[swift crag]

What are you trying to accomplish here?

not "get the ground check distance" or "find the bounds size"

explain what you're actually making your game do

[deep quarry]

I want to know wheter the Rocket is on the ground or not. Therefore, I get half of the length of the meshcolliders size and perform a Physics.Raycast with it.

[swift crag]

are you trying to detect when the rocket is properly landed, or just when it's hit the ground at all?

[deep quarry]

when it's hit the ground at all.

[swift crag]

I would suggest using Rigidbody.SweepTest

It tells you if the rigidbody would hit anything when moved in a certain direction.

This sounds applicable.

https://docs.unity3d.com/ScriptReference/Rigidbody.SweepTest.html

[deep quarry]

Thanks for the input. But I still want to learn why the MeshCollider gives an error.

[swift crag]

Log the result of GetComponent<MeshCollider>().

Then, log the result of GetComponent<MeshCollider>().sharedMesh

One of these will be null.

It doesn't matter if the component exists if you grab a null reference from it and then try to use it

[swift crag]

Note that this would detect if you're pressed up right against a wall. You could use the RaycastHit to check the normal of the surface you hit and see if it's close to vertical.

But if you just care about resting on any collider, then that should work fine

[deep quarry]

Solved it. However I get a new error, saying Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported since Unity 5.. I suppose I need to make the Rigidbody Kinematic?

[swift crag]

A kinematic rigidbody is not affected by physics.

That is probably not what you want.

You need to...

• Delete that MeshCollider
• Attach a MeshCollider to the same object as your MeshRenderer
• Make the MeshCollider convex.

A convex collider is shaped like shrinkwrap.

It doesn't have any holes or dents. It's a much simpler shape to reason about

Alternatively, just slap a box collider on it and call it a day

It's probably good enough

You can use multiple colliders, too: a Rigidbody will use all colliders parented to it

[deep quarry]

MissingComponentException: There is no 'MeshCollider' attached to the "Rocket" game object, but a script is trying to access it. You probably need to add a MeshCollider to the game object "Rocket". Or your script needs to check if the component is attached before using it

[swift crag]

yes, because you no longer need to get the MeshCollider at all

you should remove that code

[deep quarry]

what code? the get groundcheck one?

[swift crag]

the code that tries to get the MeshCollider.

[deep quarry]

so how will I then get the size of the MeshCollider? :3

[swift crag]

you don't

[swift crag]

you don't need it at all; you can just ask the Rigidbody if it would hit anything

that's why I suggested using this method. it's way simpler and more reliable

your method would fail for any ship that's wider than it is tall (think a flying saucer)

[nimble hinge]

"The more you learn, the more you realize how little you know"

[ivory bobcat]

You'll never really ever know it all.. just enough to get by.

[swift crag]

It's also just fundamentally unsound. You're asking for the object-space size of a single mesh's bounding box. This isn't how big the rendered mesh is in the world (and also doesn't care about how the renderer is rotated)

[bright oxide]

Why is this returning 1? Am i missing something?

The way i understand it, Mathf.Sign returns 1 if the value is positive, -1 if it is negative and 0 if it is 0?

[polar acorn]

https://docs.unity3d.com/ScriptReference/Mathf.Sign.html

[bright oxide]

i see, cant always rely on chatgpt

[polar acorn]

You should never rely on chatGPT, it doesn't know anything. It just chains words together.

Check the documentation

[bright oxide]

wouldnt go that far but yeah

[earnest atlas]

Do UI Image have tilable settings? I want to create something like healthbar and so far its decreasing is size to middle

[polar acorn]

It literally does not know things. It has no memory, it has no concept of comprehension. It builds a probability curve of text based off of existing data, choosing words that are most likely to come in that order. It is a fancy version of the predictive text feature on your phone, just with more data.

there is no concept of "fact" only how common a set of words are

[swift crag]

most of the "magic" is just the enormous amount of data shoved into it

[rich adder]

you can simply put pivot not in the middle of rect transform

but yea there is tiled mode, stretch and fill iirc

although for healthbar i would use Fill and change that

[rare basin]

this is a code related channel 🤷

and you could test it in 10 seconds 😄

[earnest atlas]

Its just UI image looks like its not having sprite parts

[rare basin]

you need sprite to be assigned to the Image to be able to set the mode, for healthbar set it to Filled and manipulate the fillAmount in code, anyway this is not a proper channel for that

[earnest atlas]

I had no sprite set to it so I couldnt manipulate the value

[vast vessel]

Lets say i have a script that needs refrances to 3 other scripts on the same component.

Is it better to have them be public properties and assign them in the inspector? Or will it just be fine if i have them be private and assign them in Wake(), with TryGetComponent?

[earnest atlas]

fine on awake when its on same object

[vast vessel]

Wont the latter will increase my Scene load times if i have that script on many game objects?

[earnest atlas]

Its not GameObject.Find so most likely not

You can totally serialize it

I just dont like serializing

[vast vessel]

Hmmm. Well i guess ill go with it, since serializing them and having them show up in the inspector will just make things more messy.

I mean, if i dont need to see them and assign them in the inspector, then why should i have them serialized?

[summer stump]

No. Even when assigning them in the inspector, the engine needs time. There is a negligable difference between serializing the reference and a getcomponent call

But serializing is best

[rich adder]

Dependency Injection when assigment in inspector isnt possible (runtime spawns)

I never understood the "I dont want my inspector cluttered"

this is nonesense statement

[earnest atlas]

I dont like serializing objects I need in multiple objects. I just find it at 1 place and access it like this

[vast vessel]

I only understood one word of that, and that is the word inspector

Also whats wrong with wanting a cleaner inspector?

[rich adder]

its nonesense

[rich adder]

https://unity.huh.how/references/simple-dependency-injection

[earnest atlas]

DI interfaces still elude me

somehow making eveyrhing by guide they dont want to work

[rich adder]

DI interfaces?

[earnest atlas]

yeah

Im more of data manipulation course

So I was interested in making them

[rich adder]

whats DI have to do with Interfaces

[earnest atlas]

DI interface

[vast vessel]

So, when i have object pooling, reuse an object, and then reassign its properties based on my needs, in a Init function thats DI?

[rich adder]

yes but what about them?

[earnest atlas]

I dont remember

[rich adder]

they are the same way used as any other type

[earnest atlas]

Wdym?

[rich adder]

its when you "inject" a required reference

if your pooling needs to inject something in the pooled objects sure

[rich adder]

Interfaces are used quite often in traditional DI pattern

its part of the SOLID principles

[earnest atlas]

Well I tried implementing them when was working with windows and then in android with dagger, but in first case it didnt work in second it absolutly broke my app

[safe root]

https://gdl.space/zezuwamubu.cpp

My character isn't looking around and I don't know why

[rich adder]

strange, I use it very often esp with traditional .NET apps.

[earnest atlas]

    {
        float forwardInput = Input.GetAxis("Vertical");
        float rightInput = Input.GetAxis("Horizontal");

        characterMovement.Input(forwardInput, rightInput);
    }```

Where does this lead?

[earnest atlas]

I probably will get it at some point. It wasnt really needed at that stage and was more of experiment of mine

[summer stump]

I don't think they were saying that the d stood for DI
Just that the concept of separation by using interfaces aligns with SOLID

[rich adder]

[rare basin]

that's not what they meant lol

[rich adder]

where is CharacterMovement

[safe root]

My character moves i just need to have it look

[storm imp]

@polar acorn world canvas?

[polar acorn]

The canvas your image is on. Is it a world space canvas or a screen space one

[rich adder]

btw you should notmultiply Time.deltaTime on mouse Inputs

[summer stump]

Brackeys!!

[storm imp]

how do I check

[rich adder]

permanent wound

[polar acorn]

What did you set the canvas to when you made it

[rich adder]

Add debugging the values making sure they are what you expect them to be

[earnest atlas]

new DataHold(_images[0],0,GameController.Instance.Health)

I want to save link to Instance otherwise it will just save the value. Is it possible?

[storm imp]

how do I make it so that I can move in the photo?

[safe root]

Well when i turn with my mouse, nothing happens

[rich adder]

thats not debugging..

[polar acorn]

Either move the image on the canvas instead of the camera, or use a world-space UI so that the camera moving actually matters
https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/HOWTO-UIWorldSpace.html

[rich adder]

thats stumbling on the same problem

[summer stump]

You mean the logs don't show in the console?

[storm imp]

but I followed this tutorial and it worked for him

https://www.youtube.com/watch?v=LLk4EYrcBQE&t=5s

[rich adder]

oh boy..

[carmine elm]

if i have more than one class in a script how can i acess a variable from it . if i do the normal thin like: ...GetComponent<.....>()....=0, it s says that isn t a definition for that.

[summer stump]

Hundreds of people tell us they followed tutorials, and there is always something they missed

[safe root]

Well if it doesn't at all, I can asume that they are zero or there's a mistake within my code that doesn't read the code

[summer stump]

Did you add debug.logs?

[rich adder]

assuming is never a good option in dev/coding

you have to BE SURE

[summer stump]

Have only one class in a script, first of all.
Second, getcomponent finds a type, so script files are irrelevant to it

[storm imp]

so which one is easier?

[polar acorn]

They don't move the image in this tutorial. They've made a UI that they hide when you start the tour

The image doesn't move

[rare basin]

there's no easier or harder solution

just A or B

[carmine elm]

so for example i have GameObject.GetComponent<"Player">().health

not the script just the int

[summer stump]

No quotation marks

Remove those

[carmine elm]

i did

[summer stump]

GetComponent<Player>().health

[rich adder]

Player is a component not a string

[summer stump]

Ok, so what is the issue then?
It says there is no Player or no health?

[storm imp]

but 14:30 of the tutorial he can move the photo

[carmine elm]

Player is the script

[safe root]

fari and it's within the Lateupdate

[summer stump]

Class, not script

[rich adder]

Component = Script

[safe root]

Nothing happens pass that

[rich adder]

fari ?

[polar acorn]

He's not moving a still image, he's rotating the camera inside a sphere with a texture on the inside

[storm imp]

yes

[polar acorn]

This tutorial is specifically on how to make a menu that swaps that material based on your input

The menu doesn't move

This is part 3. Did you view the first two parts

[storm imp]

yes

[polar acorn]

Show your sphere then

[safe root]

Fair and scatch that. everything goes through but I can't turn my camera

[storm imp]

The menu is not supposed to move when you click the button it brings you to the first photo and you're supposed to be able to move in the photo

[rich adder]

"everything goes through"
show what you did and what values you are getting, its all guess work from this end rn

[polar acorn]

Right, so show your actual sphere with the texture you're trying to move inside of

[safe root]

Well I put simple messages saying that it works

[polar acorn]

Okay so you do have the sphere. Show the inspector for the object that controls the camera's movement

[rich adder]

thats not good debugging, no. You Debug VALUES

[polar acorn]

No, the one that moves the camera

Whatever object has that script on it

Also you haven't assigned any sites to this object

[summer stump]

Wait, is the issue that the menu picture doesn't go away?
After what digi said, show the button's onClick in the inspector

[safe root]

What values would I put?

[storm imp]

No the issue is when I click the button on the menu I go to the first photo but I cannot move around

[summer stump]

#💻┃code-beginner message

[polar acorn]

Still waiting to see where you are actually moving the camera

[rich adder]

um ok for example

void LateUpdate()
{
   Debug.Log($"xAxis value is : {xAxis}, yAxis value is : {yAxis}");

   Quaternion newRotation = Quaternion.Euler(xAxis, yAxis, 0f);

   Camera.main.transform.rotation = newRotation;
}```

[carmine elm]

Now i have can t refference to the variable because the class from the other script has to be MonoBehaviour

[summer stump]

It has to be a MonoBehaviour, yes

Component is a type, which MonoBehaviour inherits from

[carmine elm]

so besides that what can i do

[summer stump]

GetComponent only works for things that inherit from it

[summer stump]

What do you WANT to do? This is an xy problem

[rich adder]

what are you trying to do in the first place ?

[carmine elm]

i wan to do an DataSaver

[polar acorn]

https://unity.huh.how/references

[rich adder]

What about it

it should be probably a Plain class that holds data

[storm imp]

this?

[safe root]

Those put a lot of errors

[summer stump]

No

[polar acorn]

No show the object that moves your camera

[summer stump]

There is no script that moves anything there

[rich adder]

what is the error show me

[summer stump]

You should know which script has code that moves the camera. Show that one

[summer stump]

I see you have two tour managers
#💻┃code-beginner message

And should the CamerController not be ON the camera? Could be wrong since I haven't seen the code

[storm imp]

where do you see two?

[polar acorn]

this one and the one you showed before

the one that had nothing in it

[summer stump]

One in the message I just linked..

[safe root]

I kinda can't since it's on my friends computer and he gotta get Discord. ((Were in school in a game design class. The teacher isn't a coder))

[polar acorn]

So your camera controller is rotating this object, which seems to contain the camera and the sphere. So it's moving everything at once

[summer stump]

That's not what the tutorial had. Just sayin

[rare basin]

so why are you talking for your friend

[rich adder]

Well idk what to tell you, the line I sent you would produce literally 0 errors

[storm imp]

what did I do wrong

[summer stump]

What digi just said

[polar acorn]

Actually they have the spheres on the wrong object

[summer stump]

Ahhh, got it

[polar acorn]

Why are your spheres a child object of your camera controller

[dusty silo]

I am wondering: if you put a script onto a prefab, will the script's constructor be called, or would I have to use start/awake?

[carmine elm]

https://pastebin.com/4bXgddkL I want to acces the variable from stats class to acess it from other scripts.

[summer stump]

Don't use Constructors on monobehaviours

[rich adder]

Monobehavior and SO dont have constructors

[languid spire]

you cannot have constructors on Monobehaviour scripts

[storm imp]

again I followed the tutorial unless I did it wrong and made a mistake

[rare basin]

well you can technically

[dusty silo]

Point taken. Any idea why?

[rich adder]

You've made your spheres child objects of WorldCenter

[languid spire]

you can, technically, make a MonoBehaviour IDisposable, ever tried it?

[storm imp]

Is that wrong?

[summer stump]

Yes

The screenshot there is from the tutorial. Notably, the spheres are NOT children of WorldCenter

[rare basin]

yes as i said, you CAN, you said "you cannot"

[storm imp]

how do I fix that?

[languid spire]

ok, pedant, should not, happy now?

[summer stump]

Make them... not children?

[polar acorn]

Instead of doing that, don't

[storm imp]

do I drag them ontop of the worldcenter?

[summer stump]

Uh no

That would make them children of WorldCenter. Which they already are

Drag them into a blank space

So they are children of the scene only

[storm imp]

then what should I do instead

[summer stump]

I literally JUST told you

You should scroll up like two posts

tbh the links are not relevant to his problem, it's a POCO

You moved the camera

You needed to move the snow sites (the spheres)

[storm imp]

all three?

[summer stump]

WorldCenter needs the camera as a child

[summer stump]

Yes, of course

[rocky canyon]

if ur following a tutorial just make it look like the tutorial.

[rich adder]

You access them the same you access everything else in c#

[rich adder]

true but the class resides on a MB i think

[languid spire]

@carmine elm SaveDataObject.stats.something

[rich adder]

not clear how they want to grab it

[summer stump]

The poco could be held by a singleton, then he accesses it through that
Or a serialized field
Both of which are shown in the unity.huh.how link

[rich adder]

there is a field for it though
public SaveDataObject SaveDataObject;

so they need to access that field i assume from DataManagerSaver which is MB

[rocky canyon]

i hope ur mispelling the name of that variable

ohh ur not..

public SaveDataObject SaveDataObject; this is no bueno right?

having the exact same name as the class

[polar acorn]

Please read the things you're being told to do

why did you move the camera

[rich adder]

yea it works but VS sometimes takes a shit

[polar acorn]

that was never suggested

[rich adder]

I would never use same name though

[storm imp]

like this?

[polar acorn]

Make the spheres not a child object of the camera controller

[rocky canyon]

ive noticed lately that Unity lets u name the class differently from the filename now

[polar acorn]

yes

[rocky canyon]

i dont do that, b/c its asking for errors imo

[storm imp]

now it should work?

[rocky canyon]

[rich adder]

I usually do public SaveDataObject CurrentSaveData {get; private set;}

[rare basin]

yes only in 2023+ versions tho

[rich adder]

maybe a unity backing field if needed in inspector

[rocky canyon]

imma stick to normal naming.. (same as class) b/c i already confuse myself

[rare basin]

yes same, dont see a reason to have different file name than the class

would be confusing to me and other programmers in the team

[rocky canyon]

absolutely

[rich adder]

for MB?

[rocky canyon]

yessir

[rare basin]

class BossFight, filename NormalMobFight lol

[rich adder]

yeah I rather keep MB named same as filename

it works now thank you sooooooooo much for the help @summer stump @polar acorn

[rich adder]

eg one file can contain multiple classes related to each other

having a bunch of files for small classes sometimes is more clutter

[rocky canyon]

yea, thats a good example..

i was thinking the same.. if u have multiple classes within 1 file..

u can chose w/e is relevant

[rich adder]

Just wished we had File-Scoped namespaces tho 😭

[scarlet skiff]

when colliding with a gameobject that is a parent, is it possible to check for what part of the parent it collided with? say that the parent has a collider but also a child of the parent has a collider, can u check which one it collided with? code wise

[dusty silo]

Is this okay, or should I use getComponent?
Edge e = Instantiate(Resources.Load("Prefabs\\EdgePrefab")) as Edge;

[rich adder]

I think the Collision holds info on which collider was hit

[rich adder]

what reason you want to do this ?

[scarlet skiff]

cuz im doing something like this but its not exactly working
(i know that using names instead of tags or wtv is bad but ill clean it up later)

full method

both the force field and the shiled have trigger colliders

wait.... is it cuz none of them has a rigidbody? i think i didnt give either a rigidbody..

[summer stump]

1. You never want to check by name
   Use tag, type, layer, ANYTHING else

[rocky canyon]

well, thats atleast (1) reason

[summer stump]

2. if you have a rigidbody on the parent, it will treat all the colliders as a composite collider

I always recommend simply having the OnCollision/OnTrigger code ON the children, and pass pertinent collision data up to the parent

[scarlet skiff]

thing is i want it to ignore the force field, not collide with it, and just collide with everything else

[rich adder]

Yup usually my child colliders send data to parent

[summer stump]

Then disable collisions between those layers with the layer matrix I guess

[scarlet skiff]

well.. i want some projectiles to bypass, and some not

currently i have 4 layers for the collision, to do it via layers, id need 2 more layers for this

do i just do it anyways?

or try a diff appraoch

[rich adder]

you can just do ignore for the colliders

it doesnt have to be layers

[native seal]

what should I consider when choosing to use a singleton vs a static class?

[summer stump]

Yeah, that's why doing it that way sucks.
Make the forcefield a child object and just check that it's the right thing

if (collision.gameObject.TryGetComponent(out Projectile proj)) {
  if (proj.type == typeICareAbout)
}

Something like that

[rich adder]

so you can assign specific colliders to collide or not

https://docs.unity3d.com/ScriptReference/Physics2D.IgnoreCollision.html

[rich adder]

static class = helper functions and such
singleton for gameplay persistance

imo

[native seal]

why is that the case though?

cause it seems static classes can work for tha ttoo

[rich adder]

Just personal thing I do, so take it as opinion and not fact.

static can cause more problems than it can solve sometimes

the instance itself is static and is fine for me when doing singleton

[low path]

helper functions are things that generally don't need state. the static class is just a namespace. if you have something in unity that is part of your game logic and has state, you generally want to be able to control it with scene controls, etc.

like reloading a scene or something will just reinitialize. otherwise you will have to manually re-initialize the static class, which is another place bugs can happen.

[rich adder]

you have to make everything in a static class static or else methods can use members etc.. its kinda bad pattern imo

[low path]

also, monobehaviors can't be static classes, so you can't do things like update

[native seal]

okay so for example, I have a Save System and and Item Database, does it make more sense to make them singletons or static

[rich adder]

also you cannot see static variables in unity inspector etc

[native seal]

the save system just saves/loads all stuff on exit/enter and the item database holds a SO that has all the items avaliable in my game

[summer stump]

Singleton imo

[rich adder]

I have both for a save system

the system that deals with System.IO is static class

the one that interacts with MBs(gets data to pass to static IO class) is static instance (singleton)

[summer stump]

Ok, yeah that's fair

[low path]

i think static class is fine for a save system because you can make the save system without any state - it reads stuff from disk, puts it int your game objects, etc., or does the opposite.

[native seal]

same with the item database no?

[rich adder]

database , system file same crap

[native seal]

i just holds a list of items that can be accessed

[low path]

personally i'd not use a static class for the database because i'd like to be able to plug it into the unity inspector

[native seal]

thats why i use an SO to hold all the items

[rich adder]

use the most basic database . Json file xD

[low path]

but if you want to just have it completely separate, that's fine i guess

[scarlet skiff]

lol what if i just do something like this tho? it has to be true if it wants to run the code that is usually run when colliding with the player, and considering the force field is a trigger collider, it might work?

[native seal]

json cant serialize SO's correctly

atleast from what ive tried

[rare basin]

SO cant be serialized at all

[native seal]

yea

[rare basin]

its not about json

[rich adder]

Serialize the data on the SO not the SO itself

[native seal]

I do

[rich adder]

then it should be no problem

[native seal]

my save system saves the name and then gets the name on load

to build the item

i know thats not my issue im just wondering about the singleton/static thing

[rich adder]

thats bad

I put a POCO on the SO and serialize the POCO

getting names sounds horrid

[low path]

singletons are more for like... managers/controllers within the game itself. things you definitely dont' want/can't do with a static class

[native seal]

wdym poco

[rich adder]

Plain old C# object ( a regular class)

[native seal]

why can't you though

[rich adder]

or plain old clr

w/e

[low path]

well again, if you have a manager that needs monobehavior functionality, it can't be a static class

[summer stump]

Again, the first thing you should do is remove anything that is checking the name

[low path]

or if you need to use the inspector

[native seal]

okay so thats the only difference really

[low path]

and also, it's easier to deal with scene changes/reloads using monobehaviors

[summer stump]

This was my recommendation in case you missed it
#💻┃code-beginner message

[low path]

yeah but it's a big difference

[rich adder]

what are you trying to do ? I dont understand exact use case

[summer stump]

Have some projectiles stopped by the force field and some pass through is my understanding

[rich adder]

Ohh wouldnt the Ignore collision method work here?

[native seal]

so you make a seperate class for each item on top of the SO for the item?

[summer stump]

Yeah. They expressed concern over adding a bunch of layers though

I dunno how many they need

[rich adder]

nah but Ignore collision just needs colliders

no need for layers

[summer stump]

Oh, or do you mean the PROJECTILE would ignore it for different types...

Yeaah, I hear you

[scarlet skiff]

if the arrow hit the force field, canHitPlayer is set to false, otherwise its set to true, in the players collision script, i check if the player collided with the arrow and if canHitPlayer is true, only then id run the script that damages the player, destroys the arrow etc

[rich adder]

Oh so its not working like that ?

[rich adder]

depends on the usecase but I need a POCO yes for mutable data, since SO should not be mutable

[scarlet skiff]

what do you mean?

its what i was gonna try, is what i meant, so i was asking iof that could work, rather than using collision2d,ignore()...

[native seal]

I dont see the issue with rebuilding from my database with a name

could also use a guid

[rich adder]

they both can work, one of them will still make arrow hit player collider tho no?
Ignore collision method will make the arrow pass player completely, so its a design choice

[rich adder]

a guid for what?

[scarlet skiff]

yes, i do wanna hit the players colliders, just not the force field

and it works now!

[native seal]

when I save the data on quit, i save each item's name, index in inventory, and stack amount

then when I load the game back up, it rebuilds the items using the name

fetching the SO/item from the database

[rich adder]

yeah you're recreating it

I used guid before when making items that cannot respawn if you Load a game

like chests that already hold items picked up etc

had to tap into the SerializableDictionary realm

it was annoying

[native seal]

so what I'm doing is bad?

the only issue is when changing item names and using a GUID wouild fix that, I just haven't implemented it yet

[rich adder]

Where did I say that?

[native seal]

you said

[rich adder]

Ohh I thought you meant you were getting references back by names, I misread

[native seal]

ah okay

👍

[stuck cliff]

Does anyone know if there is a C# script for a 2d game, basically I want to create a mechanic, that after the knife cuts the bread (goes through all the bread collision) changes the sprite

[rich adder]

is there an exact c# script for the specific thing you want ?

not likely.
dissect the problem into smaller ones and build it yourself

[native seal]

maybe on collision exit?

[rich adder]

do you have an example of this ?

[stuck cliff]

yes

Im trying to make a game, in that game I will pick the knife with the mouse then i need to cut the bread

and i had that idea

[rich adder]

You could def do a raycast from mouse to the bread collider or something

[stuck cliff]

Ye sure cuz i dont have no idea how to do this

[rich adder]

well, for example "pick the knife with mouse"
How to move objects with mouse, step 1

something like that

[stuck cliff]

oh i already know how to do that

[rich adder]

well there you go

when you solve those smaller issues you build up to the thing you want

[violet falcon]

Hello i have an error on a code that " SceneManager.LoadScene" giving me this error "Severity Code Description Project File Line Status Deleted Details
Error CS0117 'SceneManager' does not contain a definition for 'LoadScene' Assembly-CSharp D:\GAMES BY ME\Pixel Run\Assets\Scripts\menum.cs 22 Active
"

[stuck cliff]

alr

ty

[rare rivet]

How can i tell if i have collided with the parent of a group and not a child? When I tried collision.transform.name(name) it still fired on the child object

[polar acorn]

You have made a script named SceneManager

[rare rivet]

I have reasrched with no lick

[violet falcon]

i just added this at begging "using UnityEngine.SceneManagement;"

[polar acorn]

And because you have made a script named SceneManager, your code is trying to use that instead of the one from UnityEngine.SceneManagement

[violet falcon]

i dont have any script called like that

[polar acorn]

Are you using visual studio?

[rare rivet]

Yo could anyone spare a second?

[violet falcon]

yes

[storm imp]

how come I get this hold on when I hit play?

[polar acorn]

Go to the line the error is on, put your cursor over the SceneManager text and press F12. Screenshot what comes up

[violet falcon]

It magically just fixed, thank you

[rich adder]

infinite loop

[storm imp]

is that bad?

[polar acorn]

Is it just stuck on that load forever

[rich adder]

if its not entering playmode and stuck, yes lol

otherwise just disable the Domain Reloading and you're gonna be in playmode in a fraction of a second

[storm imp]

no it just takes a long time 30s-1minute

[rich adder]

disable this then
https://docs.unity3d.com/Manual/DomainReloading.html

[median ruin]

void Start()
    {
        CursorText = GameObject.Find("/GameHUD/Popup/CursorText");
        CursorText.GetComponent<Text>().text = text;
        CursorText.SetActive(false);

    } 

Is this incorrect? What does "Object reference not set to an instance of an object" mean?

[crystal venture]

I'm doing some practice with the basic movements, I managed to make a cube move, rotate and jump.
I would like to implement a jump similar to Mario Bros but in 3D, can you help me?

[rich adder]

but yeah you possibly have lots of script doing GetComponent, or something heavy in Start/Awake @storm imp

[rare rivet]

Rigidbody addforce?

[polar acorn]

It means something on that line is null but you're trying to use it anway. What line has the error

[median ruin]

21, the middle oe

cursortext null?

[rich adder]

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

[crystal venture]

I did all basic movements with AddForce/Torque

[polar acorn]

Then either the find fails or it finds an object that does not have a legacy text component on it

[rare rivet]

Ok so how do you want your jump to be different

[median ruin]

I see

[rare rivet]

How can i tell if i have collided with the parent of a group and not a child? When I tried collision.transform.name(name) it still fired on the child object

[crystal venture]

Using this method I was only able to make the cube jump by a set amount

[rare rivet]

And u want it to jump by an inset ammount?

[rich adder]

collision.transform.parent.name

[rare rivet]

Tryed

Threw eeror

Error

[rich adder]

which error ?

[rare rivet]

Nullexception

[hardy tartan]

hey

[rich adder]

then your object hit has no parent

[rare rivet]

Bruh it does rho

Tho

[rich adder]

computer says otherwise according to you, so i incline to always believe computer

[rare rivet]

Totally fair, but i can see that a parent is attached with a name

[hardy tartan]

dumb dumb question, i have a .unitypackage file thing i wanna import, but it's not showing up as a .unitypackage file extension thing, it showing as GZ, help pls, (very new to unity)

[rich adder]

then its probably not the collision.transform you think it is

[rare rivet]

There are multiple types?

[median ruin]

Is there a different way than gameobject.find

[crystal venture]

I want if I immediately release the jump button the cube jumps a little and depending on how much I press it (not infinitely) it jumps more, just like in Super Mario games

[silver flicker]

hey, so im trying to get the value of the angular velocity in an rb2d in order to make a drifting-type system, although its constantly at 0. Currently I'm changing the rotation of the object dependent on the mouse location on screen, anyone know why its constantly set to 0?

[rare rivet]

In update have an if statment looking for jump button pusing up, and if you release it stop

[rich adder]

show where you put the debug and which object

[wintry quarry]

Find is not recommended for use, but it's not Find that's the problem in your case. You're using GetComponent with a component type that isn't on your object.

https://mikeadev.net/2015/08/variable-jump-height-in-unity/

[median ruin]

I see... I might have misunderstood my components name

[silver flicker]

^ nvm

[median ruin]

How do I get TextMeshPro from a GameObject?

[rare rivet]

The script is attached to a cube that is also a child,and the aim is that i want the if statement to fire only if the object the script is on hits the parent of the other one

[crystal venture]

Does it also work for 3D?

[rocky canyon]

physics are physics, and math is math

[rare rivet]

I didnt need a debug cause it theew an error

[rocky canyon]

just use Rigidbody vs Rigidbody2D

[rich adder]

!screenshots

[eternal falcon]

No

Be mindful, if someone requests your code as text, don't send a screenshot!

[rare rivet]

Mb, im on my phone rn

And i cant use discord

[median ruin]

dusty code

[rocky canyon]

since you putting it out there for the world to see, clean your monitor bro

[rich adder]

use the browser version

[rare rivet]

Blocked :(

School coding is crazy

[median ruin]

very dumb of school...

[rocky canyon]

u just blocked the only person thats probably gonna help ya

oh u mean teh website is blocked

[rare basin]

that will fix it

[rocky canyon]

i read that wrong

[rare rivet]

Lol ok i get it i wont picture

[median ruin]

pretty

[rare rivet]

@rich adder I could use my hotspot if u think u would be able to help with the text code tho?

[rare basin]

bunch of text objects

appearing after delay + input fields

[rich adder]

certainly wont hurt

[rare rivet]

Alr

[fervent abyss]

Can I somehow remove first line of the text and add a new last line?

[rocky canyon]

https://hatebin.com/otolqjmmrv

[rich adder]

Also you should always Debug.Log(collision.transform.name)

[rare basin]

sure why not?

[fervent abyss]

how

[rocky canyon]

i been using this website like wildfire lately

[rare basin]

[rare rivet]

Alr

[fervent abyss]

Thats what I kinda did but didnt find a solution

[rare basin]

what did you google exactly

[rocky canyon]

are you making some new cutting edge thing? if not google has solutons

[rocky canyon]

probably.. just the search keywords yea..

[rare basin]

googling is a skill

all devs need to learn

everything is in the internet

[rare rivet]

This debugs the corret thing and then immidetly the error

[median ruin]

I can't figure out how to get the component type "textmeshpro" from a gameobject? I looked up a unity forum thread but couldn't find a good answer

[rare rivet]

Maybe its because theres a difference between transform and gamepbjext?

[rare basin]

depends on what do you want

text mesh pro is an asset

and it has multiple components

like TexMeshProText etc

or TMP_Text

[median ruin]

I want to access this component

[rare basin]

TMP_Text then

[median ruin]

Why are there so many similar names?

[rare basin]

and what would it be?

1 name for everything?

that's not possible

[rich adder]

TextMeshPro is the Asset

Text(UI) is the type of Text component

not that diffcult

TMP_Text is the baseclass for Any of TMP text (UI and Mesh)

[rare basin]

yea, TextMeshPro - Asset
TMP_Text - text component of TextMeshPro asset

[amber spruce]

https://pastebin.com/6f3aFPX8 thats all my save stuff anyone know how i can save only a single thing i dont want to save the players position and health just the players skin and i dont want it to save player.playercontrollernew.skin i have a different value i want to save it as

[rare rivet]

Wait im trying to see if i collied with the parent object and not a child but woulnd this code fire if it hits a child too because it returns the parent name?

[rare basin]

um.. then.. dont save what you dont want to save?

and save only things you want to save? 🤔

[median ruin]

wouldn't have guessed it would be tmp_text from the name of the component

[rare basin]

could just look at the docs

you dont need to guess anything

[rich adder]

instead of assuming things just test them

[amber spruce]

how do i save another value as playerskin and only save that keep the rest the same

[rich adder]

would you prefer the original name TextMeshProUGUI

[rare basin]

put another value to save instead of the one you are putting now? idk what do you mean lol

[rich adder]

https://docs.unity3d.com/Packages/com.unity.textmeshpro@1.1/api/TMPro.TextMeshProUGUI.html

[median ruin]

I would, or merely the component name

[languid spire]

you are not suposed to guess, you are suposed to read the docs

[rocky canyon]

i like..

i use it for everything.. then if i need a specific i'll change it if/when it doesnt work

[amber spruce]

how do i have it only save the specific value i want to save without overwriting the others

[rich adder]

too long to type

[rare basin]

i have 0 clue what do you mean

save the things you want

[rocky canyon]

make a function that just saves that 1 part

[rare basin]

and dont save thing you dont want

[rocky canyon]

instead of saving all of em..

[median ruin]

well unlike you I like my time spent on doing code not looking up what things are named

[grand forge]

hello im new to unity u think a 2d platformer is way to go for first thign

[rare basin]

docs are part of coding

[rocky canyon]

lmao.. thats a weird thing to say..

[rare basin]

yea it's insane xd

[rich adder]

oh lord.. this statement is nonsense

[rocky canyon]

unlike u I like driving my car, instead of going out and purchasing a car first

[rare basin]

some people thinking logics are just crazy xD

[languid spire]

which is why you are here asking stupid questions and I am answering them

[grand forge]

just like a small 1

[wintry quarry]

Use the correct class name. TMP_Text is the safest bet

[glass urchin]

how does the layerMask bitmask thing work?

[rocky canyon]

think even smaller

but yea a simple 2d game would be the best first project

[glass urchin]

I'm seeing someone use negative integers and I'm confused

[grand forge]

just like 1 where u jump and collect like barrells or smt

[median ruin]

TMP_Text doesn't seem to work

[rocky canyon]

ya, sounds good man

[amber spruce]

public void Save()
{
    float playerSkin = selectedOption;

    SaveObject saveObject = new SaveObject
    {
        playerSkin = playerSkin
    };
    string json = JsonUtility.ToJson(saveObject);

    SaveSystem.Save(json);

}

so this wont overwrite the players location and health right

[grand forge]

thanks

[spiral narwhal]

Will Instantiate(this) create a new copy of the entire game object of the script?

[languid spire]

yes

[wintry quarry]

assuming this is a MonoBehaviour, yes

[spiral narwhal]

Including the parents?

[wintry quarry]

no

[rocky canyon]

i believe w/o anything else.. ya this is referring to the GameObject

[languid spire]

mo

[wintry quarry]

only the children

[spiral narwhal]

Okay thanks

[languid spire]

no it is not

[rocky canyon]

then its the MonoBehaviour?

[median ruin]

TMP_Text is not in the namespace editor says

[prime cobalt]

Does anyone know how could I use code to make it so I can grab, drag, and resize UI elements like this in game like I can in the editor? Similar to what I'm doing in this video.

[languid spire]

it is this class

[wintry quarry]

What? It's not in what namespace? If you get an error message, share the full message.

[rocky canyon]

ahh, ok my mistake

[polar acorn]

Did you import the TMPro namespace

[rocky canyon]

did you include the using TMPro; using statement?

[rare basin]

or did you import TMP Essentials at all

[rich adder]

no because they rather spend time coding

[rare basin]

lmao

[languid spire]

not coding if all you generate is compile errors

that's just writing

[median ruin]

The type or namespace name 'TMPro' could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'TMP_Text' could not be found (are you missing a using directive or an assembly reference?)

[rocky canyon]

find an asset that does it for you.. if not thats a ton of coding.. an entire system

[polar acorn]

Do you have TextMeshPro installed at all

[rocky canyon]

ya, answer the question

[median ruin]

I don't know if I do

[rocky canyon]

did you include the using statement ^

[rich adder]

if only there was something that told you which namespace

[rocky canyon]

if ur not sure then its probably not installed

[median ruin]

yes

[wintry quarry]

TMP is installed by default in most new projects

[rocky canyon]

the only thing u need to do is go in there and import the essentials

[prime cobalt]

Ok, good to know.

[rocky canyon]

after you pull in the essential stuff it should be ready to rock n roll

[amber spruce]

it just overwrites the other save info

[rich adder]

doesnt that just Import like materials and shaders n stuff

[median ruin]

Thought it was supposed to be simpler...

[rare basin]

then make other function

[polar acorn]

I don't think that's relevant

[rare basin]

and dont save the other things

[rocky canyon]

no clue what it does, lol.. Anytime i add a TMPro element the popup thing pops up and asks me to import em

[polar acorn]

The namespace is part of main package

[rare basin]

life's not easy

[rocky canyon]

ohh.. well then i'll ignore it next time..

i thought it was a requirement

[amber spruce]

i didnt save those things i only saved the skin and it just delted the other things

[rich adder]

the TextMeshPro package is already in Unity but yes it asks for that to import the materials and shaders first time, idk why

[polar acorn]

You should still install it. Otherwise you're making all your font assets yourself

[median ruin]

Don't talk to me if your just gonna be rude

[rocky canyon]

ahhh okay.. never knew exactly what it does.. so its just the basic stuff.

[rich adder]

I recall someone had pink font without it

[rocky canyon]

the Liberation Font.

a classic

[languid spire]

oh, was that what that was caused by?

[rocky canyon]

ive never seen pink text before 👀

lol

but i always import those starter things.. so thats probably why

[rich adder]

Usually fixed it after they did Import Essentials, unless the prefab or whatever was already using the missing Liberation font + shader

[languid spire]

I remember it, don't think we ever found the cause

good to know

[rich adder]

wait nvm thats the mapping

[median ruin]

my version is 2022.3.11f1

[rare basin]

sorry won't waste my time on you anymore

[rocky canyon]

The TextMesh Pro UPM package is already included with the Unity Editor and as such does not require installation. TextMesh Pro "TMP" does however require adding resources to your project which are essential for using TextMesh Pro.

i was gaslit !

[wintry quarry]

where is your script file? Is it inside a folder with an assembly definition?

[rocky canyon]

ive never read teh TMP docs.. nows a good time i guess 😄

[median ruin]

not sure what that means

[wintry quarry]

show us

[rich adder]

I used to read the old ones but they finally made it somewhat legible for UnityPakage one

[wintry quarry]

where is your script file
what folders(s) is it in

[polar acorn]

Without it your text will have no fonts or materials so it is essential. It's just not related to this problem, since it doesn't introduce any new code

[rich adder]

yeah sometimes a Regen Project Files fixes this

unless the error is Unity not VS ofc

[rocky canyon]

Curl error..

[rich adder]

UnityTls

clever name

[rocky canyon]

ive had soo many issues with 2022.3.5

just random errors every time i boot lol

[median ruin]

In explorer? unity project?

[rare rivet]

@rich adder i know you dont care but for closures sake thank you and i was suppsosed to do col.collider.gameobject.transform.name

[rich adder]

you're many versions behind lol

[swift crag]

where did that second error come from?

[wintry quarry]

Either one? It's the same file structure

[rocky canyon]

i think he means what folder within the project

[polar acorn]

yes

[swift crag]

that smells like a networking problem

[rocky canyon]

lol, no clue thats a new one for me

[swift crag]

click on the darn thing

[median ruin]

Assets\FPS\Scripts\Game

[rocky canyon]

🤣

its a third party asset..

no worries

[rich adder]

what makes you say that lol
I was just trying to get you to debug objects you hit, but yeah that makes sense why it would need the collider.gameobject not the transform

[wintry quarry]

ok and are there any assembly definition files in any of those folders? What is "FPS"? is that a premade asset thing?
