General rule of thumb: Reuse shamelessly as much as you can, but always do a little bit of refactoring every time you touch a script

You can ship-of-theseus that brackeys character controller into something halfway decent with enough uses

[low wasp]

Right on, those were my thoughts on it. I just kind of felt like a cheater or imposter.

[echo mountain]

I'd say it's bad not to reuse. Just remember that if "the only tool you have is a hammer, everything looks like a nail". The danger is that you might find yourself using the same solution again and again for many different problems, even if often times better or easier solutions can and should be custom-made.

[polar acorn]

If you hit a screw hard enough with a hammer it becomes a nail

[wintry quarry]

Can you show the inspector of the enemy object?
Can you show your logs when this happens?

[slender nymph]

this was effectively resolved in #💻┃unity-talk

[wintry quarry]

Before I loook - my guess is this script was attached to the enemy

[paper nexus]

Yeah, that seemed to be the issue. Thanks Boxfriend.

[wintry quarry]

yep

[paper nexus]

So I know that I needed to remove the script from the enemy, but can I get an explanation of why logically, the enemy was just disappearing? Was it cause the OnTriggerEnter script was being ran by the enemy as well?

[slender nymph]

yes

[polar acorn]

OnTriggerEnter runs whenever the object this script is on has a trigger interaction (something's rigidbody touches something's trigger collider).

This function runs Destroy(gameObject) no matter what. Whenever this object touches a trigger, it dies

[wintry quarry]

because your code in that script's OnTriggerEnter said Destroy(gameObject);

so if that script is on the enemy, the enemy gets destroyed

    void OnTriggerEnter(Collider other)
    {
        Debug.Log("Bullet collided with: " + other.gameObject.name);
        Life life = other.GetComponent<Life>();

        if (life != null)
        {
            life.amount -= damage;

            Debug.Log("Damage dealt: " + damage);
            Debug.Log("Remaining health: " + life.amount);

            if (life.amount <= 0)
            {
                Destroy(other.gameObject);
            }
        }
        Destroy(gameObject);
    }``` See the last line^^

[paper nexus]

Ohhh ok. I'm learning something here.

That makes sense. I appreciate it.

[wintry quarry]

code does what you tell it to do 🙏

without complaint or argument

Instead of directly having the VR hand move the hand rigidbody, create a layer of indirection:

• VR hardware moves an empty "hand target" object
• The hand itself with the Rigidbody on it has a script that follows the hand target in FixedUpdate with rb.Move(handTarget.position, handTarget.rotation);

that will make the joint behave properly

[fervent abyss]

okay

[fervent abyss]

thanks

i have memory loss

[tribal python]

Hi, does anyone have any idea why this simple code is returning wrong delta values?

private void Update()
{
        Vector2 mousePos = Mouse.current.position.ReadValue();
        Vector2 mouseDelta = Mouse.current.delta.ReadValue();
        if(mouseDelta.magnitude > 0f)
            Debug.Log($"Mouse pos: {mousePos}, Mouse delta: {mouseDelta}");
}

[polar acorn]

What's wrong about it

[tribal python]

delta values are not matching the difference of mouse pos

[polar acorn]

https://discussions.unity.com/t/mouse-delta-input/736095/40

Seems like it's related to how the input system handles polling. There's apparently multiple times per frame that the mouse position is "updated" and the delta is only the last one?

Seems like an oversight, but I think it's meant to be used for event based rather than polled in update

[tribal python]

Thank you for the response! Actually I Initially tested on event based approach, but the results are the same with update one..

Why is my code not associating with unity? intellisense doesnt work and the public walkspeed var doesnt show up in my inspector?

[slender nymph]

for intellisense, you need to get !vscode configured 👇

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

https://on.unity.com/vscode

[slender nymph]

as for the variable not appearing in the inspector, you either have compile errors or you need to save your code and make sure it compiles

[proven matrix]

Ooo okay ty

[dim yew]

where would i change the language version?

i can't open the csproj properties for some reason

[steep rose]

you can check this out if you are using VS, oh nevermind I thought you mean actual language 😅
https://learn.microsoft.com/en-us/visualstudio/install/modify-visual-studio?view=vs-2022#modify-language-packs

[slender nymph]

just use collection initializer syntax instead of a collection expression.
the only way to change the language version to anything higher than c# 9 is to go through and patch the roslyn compiler which is not supported. and even then you'd only get syntax sugar, you wouldn't be able to use anything that requires a .net version higher than what unity currently supports. it's not worth the effort of doing all that

[dim yew]

is there somewhere i could read up on collection initializers? i'm not privy

also thanks both of you

Hi i have this gun script that i want when the rotation is more then 90 it will flip the y and its not working

[wintry quarry]

If you're relying on reading back euler angles or local euler angles from a Transform, that's not a good idea, as you are seeing.

[sterile sable]

im using the sprite renderer

[wintry quarry]

Using a sprite renderer doesn't have anything to do with what I just said

[sterile sable]

you want to see the code?

[wintry quarry]

That would be a good start, yes.

[sterile sable]

using System;
using UnityEngine;

public class GunScript : MonoBehaviour
{
public Transform bulletSpawnPoint; // Assign in Inspector
public GameObject bulletPrefab; // Assign in Inspector
public float bulletSpeed; // Set bullet speed
public float bulletSpread; // Set bullet spread (optional)
public float fireRate; // Set fire rate (shots per second)
public AudioSource shootSound; // Assign audio source for shooting sound

private SpriteRenderer spriteRenderer;
private float nextFireTime;

void Start()
{
    spriteRenderer = GetComponent<SpriteRenderer>();
    nextFireTime = 0f;
}

void Update()
{
    RotateGun();

    if (Input.GetButton("Fire1") && Time.time >= nextFireTime)
    {
        Shoot();
        nextFireTime = Time.time + 1f / fireRate;
    }
}

void RotateGun()
{
    Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    Vector2 direction = (mousePosition - transform.position).normalized;

    float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
    transform.rotation = Quaternion.Euler(new Vector3(0, 0, angle));

    if (angle > 90 || angle < -90)
    {
        spriteRenderer.flipY = true;
    }
    else
    {
        spriteRenderer.flipY = false;
    }
}

void Shoot()
{
    // Play shooting sound
    shootSound.Play();

    // Instantiate bullet
    GameObject bullet = Instantiate(bulletPrefab, bulletSpawnPoint.position, bulletSpawnPoint.rotation);

    // Calculate bullet direction with spread
    float randomAngle = Random.Range(-bulletSpread, bulletSpread);
    float bulletAngle = transform.rotation.eulerAngles.z + randomAngle;
    Vector3 bulletDirection = Quaternion.Euler(0, 0, bulletAngle) * Vector3.right;


    bullet.GetComponent<Rigidbody2D>().velocity = bulletDirection * bulletSpeed;
}

}

So you want to know what exactly? You said "when the rotation is more than 90"

I think you're actually asking if the object is facing left?

[sterile sable]

yes

[wintry quarry]

all you need is this:

float x = direction.x;
if (x > 0) {
  // facing right
}
else {
  // facing left

you don't need any of the trigonometry etc

Hi guys, i have problem and i dont know how to solve it. I am working on a student car racing game with proper RC radio (Futaba T4PM) as an input. I have a functional trasmitter to USB adapter (works fine in VRC PRO - rc racing simulator), but i cannot find a way how to make it work in my project when using the old or the new input system. Any help would be appriciated!

P.S.: I posted this message to input system thread before, but i am absolute beginner so will post it here instead.

[bold saffron]

If I use public enum Enemies {TestEnemy1, TestEnemy2} and I want to use their index number (e.g if TestEnemy1 is selected, and its index is zero), how would I do that?

[languid spire]

cast to int

[bold saffron]

enemyPrefabs[enemyToSpawn.castToInt]?

[languid spire]

do you not know how to cast a variable?

[bold saffron]

tbh idk what that means

enemyPrefabs[(int)enemyToSpawn];

the (int) is a cast to int

[bold saffron]

oooooh

so that's what doing that is called lol

thank you very much :)

What are you expecting the collider to do that it isn't doing?

[austere crypt]

Wait

[austere crypt]

Just simple trigger/collision

[wintry quarry]

what do you mean by simple trigger/collision

you mean running your code like OnCollisionEnter?
Or something else.

[austere crypt]

Yep

[wintry quarry]

OnCollisionEnter requires a dynamic Rigidbody

And it requires your object to touch another object

[austere crypt]

I tried that also

[wintry quarry]

show what you tried and what happened

because this is a really basic thing, so 99% chance the reason is you just didn't set it up properly.

[austere crypt]

Ok

Wait

I think the issue might be that your Unity Editor is drunk

hi, im putting together a script that plays a melee attack animation, im using the new input system.

i keep getting this error, but i dont know what to do to fix it

"NullReferenceException: Object reference not set to an instance of an object
PlayerController.OnDisable"

here is the code

everything else about it is fine, it should be working but i think ive missed something?

[austere crypt]

2nd statement should be Attack.action.cancled

[queen adder]

oh? its effecting both lines, 1 error for each of the lines

[short hazel]

Attack or Attack.action did not have a value (it was null). Therefore attempting to access anything with the . operator on a null reference throws that exception

[austere crypt]

trigger also not working

[wintry quarry]

you made your Rigidbody kinematic

remember I mentioned it needs to be dynamic for OnCollisionEnter

[wintry quarry]

as for the trigger not working, you still need a Rigidbody for that

[queen adder]

Attack is one of the inputs i set up with the input system, how would i make it call the input?

[austere crypt]

so i need to check kinematic box?

[wintry quarry]

no... you have that now

you need to UNCHECK it

[short hazel]

Two trigger colliders won't detect each other

[wintry quarry]

two trigger colliders will work, as long as one of them has a Rigidbody

[austere crypt]

my bad but i tried without kinematic but same problem

[wintry quarry]

show what you tried altogether

so far you haven't shown a single valid combination of settings

Once you have a valid combination, it will work

[short hazel]

https://unity.huh.how/physics-messages/trigger-matrix-3d

[austere crypt]

with kinematic ,without kinematic , one trigger , two trigger , with rigidbody , rigidbosy with trigger , both with rigid body so on

[wintry quarry]

For OnTriggerEnter kinematic doesn't matter one way or another. You just need:

• One Rigidbody
• Two colliders
• At least one trigger collider

FOr OnCollisionEnter you need:

• One dynamic Rigidbody,
• Two colliders
• neither collider trigger

[short hazel]

Make sure you've put a value in Attack at some point. In the Inspector or from the code

[wintry quarry]

ok... so now those two objects need to actually collide with each other, while the game is running

I'm noticing you put "Floor Collision" script on one of the cubes, that seems odd.

[austere crypt]

that script on had oncollision and ontrigger method

with debug log

i also tried with .moveposition()

i think unity is broken

[wintry quarry]

make sure the Rigidbody isn't asleep

moving via the Trnsform gizmos in the editor won't wake it up afaik

or jsut let the Rigidbody drop onto the other thing

rather than moving it via the gizmo

[austere crypt]

i already used moveposition and moverotation functions

[wintry quarry]

other things to check:

• The collision matrix in your physics settings

[austere crypt]

all tick

i am into this shit past 3 hour

[wintry quarry]

Do you have Time.timeScale set to 0 or something?

IDK i've never seen an issue with this

Hello,
goal : I want the screen to turn red with full screen pass renderer as the player does a 180. The screen effect(it turning red) percent will be connected as the player turns around so it wont be at 100% unless the player has done a full 180.

I have a full screen pass renderer set up and tested in code, I made the red effect a float I can control in code but how Ill approch this goal. I'm not sure, I know what I want and need to do but Im not good enough at coding to execute and the internet is not helping on this one.

[queen adder]

i have, but nothing seams ot have changed, i dont need to make a whole new project do i?

Sounds like you want the dot product.

// if dot is > 0 it is nearing 180
// if dot is 1 it is the same direction

[pure crest]

Hey guys, I have an interesting problem, I'm working on a simple mechanic to pick up an object and old it in front of the player and right now I just have it to left click. It's mostly working, except the fact that it doesn't pick up when you just click once, it picks up only when you hold the LMB for like 0.5 seconds. It's a little annoying just because it doesnt feel as snappy and I was wondering if anyone might know why. I'll post the code below

[wintry quarry]

&& GameObject.FindWithTag("InteractOnly") this part doesn't make sense

[faint agate]

var dot = Vector3.Dot(Camera.main.transform.forward, transform.forward * -1);
would this work

[wintry quarry]

Nor this part && GameObject.FindWithTag("PickUp")

[pure crest]

I'm just familiarizing myself with how tags work, its for some objects in scene that are interact only

[pure crest]

and a tag applied to only objects that can be picked up

[wintry quarry]

Yeah but you should be checking the tag of the object your raycast hit. This code is not doing that

this code is just seeing if such an object exists in the scene

[pure crest]

Oh! Ok I didn't understand that, thats helpful!

[wintry quarry]

if (hit.collider.CompareTag("Pickup")) < notice how we're actually using the hit object here

[pure crest]

Oooooh ok I see, thank you! Could that be the issue im having then?

[wintry quarry]

No I don't think this is related to the wait .5 seconds problem

i don't see anything in here that would cause that

It's probably in the Interact function itself on the object

[faint agate]

var dot = Vector3.Dot(Camera.main.transform.forward, transform.forward * -1);
if (dot < 0) {
_fullscreeneffect.SetActive(true);
}

when I do this, the screen effect happens immediately but if I do dot > 0, nothing happens no matter where I look

[wintry quarry]

you should add Debug.Log there and make sure it's being called immediately

[pure crest]

the pickup actually doesnt use the interact function, it only uses the pickUp

[wintry quarry]

You would need to record an initial "forward" direction before the 180 is performed

and compare your player's facing direction with that recorded forward direction

it's unclear what would trigger it being recorded initially though

or if there's some hardcoded or scene-determined direction that should be

or maybe you want something like "if they do a 180 within a certain amount of time" or something

[pure crest]

Also it actually does trigger the "PickUp" method, but it just moves the object to the holdPosition briefly and doesn't keep it held by the player (when its just clicked and not held down) it just only actually follows the holdPosition when I click and hold for roughly 0.5 seconds and then I can freely let go and it will stay

[wintry quarry]

Well none of that would be related to the code you've shared here

This code only handles the initial click and initial interaction

[pure crest]

"pickUp" method sets the parent of the object to "holdPosition" on GetMouseButtonDown(0)

[wintry quarry]

If the object you're picking up has a dynamic Rigidbody, this won't do all that much

[pure crest]

it doesnt

[wintry quarry]

well what scripts does it have

[pure crest]

Sphere collider

and just a basic implementation of interact that isnt being used

[wintry quarry]

well again this code doesn't do anything except on the intiail mouse click

so the behavior of holding etc has to be coming from elsewhere

unless you've modified the script

[faint agate]

I tried Camera.main.transform.forward = startPos; but its no good

i did look online for awhile before asking

[wintry quarry]

What do you expect that to do?

that's going to aim your camera in the direction of startPos.

[faint agate]

how about : startPos = Camera.main.transform.forward;

private Vector3 startPos;

[wintry quarry]

yes, that will do the opposite

it will save the camera direction in the startPos variable

although it's not a position

it should probably be called startDirection

[faint agate]

okay thank you

[copper orbit]

what happens if the value in serializefield differs from the one initialized in c# script? it always takes serializefield's value right?

[deft grail]

the inspector takes priority

[ivory bobcat]

Your default value during initialization would be the default value when creating a new instance. The new instance that you've created in the scene would have the default values when first added to the object/scene. Modifying the values from the inspector would change the value for that instance.

[copper orbit]

are you saying that the code takes priority if the object was like a prefab that was instantiated into scene?

[ivory bobcat]

A prefab would be an instance right?

[copper orbit]

is it? I dont know

[ivory bobcat]

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

Unity’s Prefab system allows you to create, configure, and store a GameObject complete with all its components, property values, and child GameObjects as a reusable Asset. The Prefab Asset acts as a template from which you can create new Prefab instances in the Scene.
So a component instance would be attached to the game object prefab. And you'd create prefab instances in the scene ect - my interpretation of it.

[faint agate]

how would I go about doing this?

[wintry quarry]

Dot product

[faint agate]

var dot = Vector3.Dot(startDirection, _180Direction);
how would I print this so I can see the direction of 1 - 180 live as I turn ?

_180Direction = Camera.main.transform.forward * -1;
I did this for the 180 the same way I did start direction, I hope that should be fine

I just did * -1 so its behind the cam

[drowsy oriole]

Hi, I need some assistance with this code. It is supposed to disable an object and enable another 2-5 seconds after it is enabled https://hastebin.com/share/urojukuzux.csharp

[eager spindle]

Your code doesn't wait until the ienumerator has finished.

In one ienumerator, disable the object then wait a few seconds, then enable it again.

All the code should be kept in the ienumerator rather than the onenable function. The only thing the onenable function should do is call the ienumerator

Additionally, you cannot just call Delay() like that, you'll need to use StartCoroutine(Delay())

Spoilers: the final code may look something like

||```
void OnEnable() {
StartCoroutine (ToggleItem());
}
public IEnumerator ToggleItem() {
// Toggle Parents here
yield return new WaitForSeconds(3)
// Toggle Parents here
}

[near wadi]

[languid rivet]

quck question.. what will Vector3.project give?
v1 vector is projected along direction vector d1.
will I get the pink line or the green line. my assumption pink line..(which would mean direction of vector d1 doesn't matter.. just the line matters)

[misty breach]

using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;
using UnityEngine.Tilemaps;

public class A_1 : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        TileBase a_1 = share_data.keep_1_1;

        if (a_1 == "Hill_11"){
            print(a_1);
        }

       
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

i dunno how to do this but

i wanna print a_1 if the value inside it is Hills_11

[night valve]

Debug.Log(a_1);

[misty breach]

a_1 is a tileBase so the string argument is wrong i wanna ask how to correct that

[rocky canyon]

a_1.ToString();

[misty breach]

not working

[teal viper]

Try it and see for yourself. It's really easy.

[languid rivet]

ya.. already did 😅 and makes sense

[night valve]

But what exactly do you want it to print? Type name? Gameobject name? According to docs tile base has .name property

[misty breach]

so basically ive made the tiles in the tilemap as scriptable objects and am calling them them acc to their grid location and storing them in a script which through a static script im calling into another script to do this

[night valve]

So you need a scriptable object name

[misty breach]

without the if statement it prints this

Hills_11 (UnityEngine.Tilemaps.Tile)
UnityEngine.MonoBehaviour:print (object)
A_1:Start () (at Assets/pic_dat/scripts/A/A_1.cs:20)

[misty breach]

yes

[night valve]

Then you'll need to map it the other way, like having tile base as a key to dictionary with scriptable object or string values

[misty breach]

could ya write the general code for it, please

[misty breach]

i'm new to c# so my words to code interpretation is bad

[night valve]

var dict = new Dictionary<TileBase, string>()
Then you access it like an array but instead of integer index use TileBase object. But this is hardly a good solution. Probably it's best to set the .name of TileBase gameobject to the desired string and then access it like tile.name ig

[night valve]

There is probably a typo there because in the if statement you compare "Hills_11" to "Hill_11" btw

[cunning raven]

hi is there a way to keep the text characters withing the box field?

TextMeshProUGUI

[astral falcon]

within the boxfield, you mean autowrap words?

[languid spire]

does the word 'overflow' mean nothing to you?

[cunning raven]

yes i think, i tried all enum settings but "Linked" mode is nearest to what i want but it does not wrap to the lastest character

[astral falcon]

Did you read steves answer?

[cunning raven]

sorry no as that does nothing to help

[languid spire]

oh, it does

[cunning raven]

ok my bad formulate of question, i'll try again, how do i keep text in the box field and have the autowrap thingy when it gets too long

[night valve]

Over-flow so like text flowing over the rect border

[astral falcon]

you could use the autosize feature

or autofit I think its called

Or you let the user enter as long as he wants while masking it and when done editing, replace the visual text with some predefined length + "..." or something.

[runic lance]

I think there's a wrapping option with ellipsis builtin with TMPro already

[astral falcon]

Ah, how convenient if so 🙂

[runic lance]

the easiest way would be to fiddle with the settings in the inspector until it's how you want it, then just copy the properties over to the code

[cunning raven]

the ellipisis mode is showing "..."

i want it to show the lastest character and hide the first ones, dunno how to explain

[astral falcon]

you want the elipsis to be at the start

can someone help me with this

https://hatebin.com/mehnnbjkwi

[languid spire]

not unless you actually ask a question about it

[drifting geode]

It just always creates new instances instead of incrementing the item amount by 1

[languid spire]

So you need to Debug the conditions in your if statement

[runic lance]

very likely you're adding a different instance of the Item class, even though it has the same properties

[drifting geode]

Yes but I've been trying to for some time

[languid spire]

how? I see no evidence of debugging in your code

[drifting geode]

Is it better to comment it out rather than remove it completely and try something new?

[runic lance]

if the Item is something like a MonoBehaviour and it's just laying around the scene, you're probably collecting a different one than the previous

[languid spire]

no, just debug it

[drifting geode]

It's a scriptable object

[languid spire]

        Debug.Log($"{item.itemName} {inventory.Contains(item)} {item.isStackable} {item.amount} {item.maxAmount}");

[drifting geode]

Oh that's what you mean sorry I'm dumb

[languid spire]

debugging 101. If your code is not doing what you expect. Print the values to the console

[drifting geode]

Oh I got it

Instead of inventory.Add() is should've used only Add()

[neon ivy]

is there an easy way to do x amount of raycasts in every direction?

[runic lance]

what do you mean by every direction?
something like a SphereCast?

[neon ivy]

no, my first idea was to get a UV sphere and raycast from every vertex into the direction of the normal. so from points on a sphere to directions away from it

[night valve]

I assume the list is part of the MonoBehavior so you'd need to call DontDestroyOnLoad on this object. Or make that list static

[night valve]

Why not use sphere cast then?

[vernal thorn]

how do i make the list static?

[night valve]

static List<some type> list;

[hexed terrace]

Making things static just to have them available across scenes isn't a good solution, you need to tidy it up yourself when it needs to go away.

[vernal thorn]

Thanks !

[night valve]

Right, was about to say this. Probably better idea would be singleton pattern or DDOL

[hexed terrace]

For Singleton, it depends on the use of the class - again, you don't want to just make everything a singleton for cross scene

[neon ivy]

because I don't need a sphere cast?

[night valve]

Well yeah, making a singleton only for holding a single list wouldn't be good. But if you actually need such persistent list, most likely it could be placed in some more complex singleton like GameManager or smth. However such manager could be just a regular gameobject with DDOL

[neon ivy]

a sphere cast is just a raycast that uses a sphere instead of a point. if I didn't need a direction I'd use an overlap sphere but I do need a direction

[night valve]

Then probably it would be sufficient to just construct an array of direction vectors and raycast them

Or your UV solution

[runic lance]

can't you get this information from the RaycastHit from the SphereCast? you have the contact point and the normal

otherwise you just need to do a bunch of raycasts, no way around it

[neon ivy]

well yea I am trying to do a bunch of raycasts, but I need to equally space them around the player

[night valve]

Right, uv sphere won't give you even distribution. But googling helps. You may consider looking at Fibonacci sphere algorithm

[neon ivy]

I think I'll try to generate an Ico sphere of x amount of vertices

[night raptor]

As tyrr mentioned, Fibonacci sphere is often used to solve just this problem. That way you should have much greater freedom to choose any number of rays you want. With ico sphere I believe you can only choose resolutions from the exponents of 4 (triangle count of 20 * 4 ^ resolution if I'm not mistaken) so you are very limited in that regard

[rustic maple]

does anyone know a possible reason why my game completely freezes when i look in the direction of the ai?

[ivory bobcat]

Does the editor freeze/stop-responding?

If so, perhaps there's an infinite loop else we'd need to know more information.

Also check your console logs in the case that there's an error.

At a closer look, it seems as though you've simply paused the game or it has paused for some reason.

[white rune]

https://paste.ofcode.org/sufg3eQEmEGE9LmgLbLrJu
I've been tryina code up a neat lil platformer and it seems like there is a flaw with how I've created the walljump functions with the logic or something, and I cant for the life of me figure out what the problem with it can be

[wintry quarry]

Probably due to error pause

[ivory bobcat]

Can you describe the unwanted behavior?

[wintry quarry]

You got an error so the game paused because of error pause being turned on.

[white rune]

Basically the character slides up the wall when you try to scale it with jumping, occasionally the counter force does something but its incredibly inconsistent

[ivory bobcat]

Place some logs and see what your velocity is and your gravity scale. I'm assuming your gravity scale is zero and your velocity in the y axis is positive.

[tulip nimbus]

Why does this script not change the Scene? Im using UnityEngine.SceneManagement

[languid spire]

do you have a scene called Mainmenu ?

[tulip nimbus]

I do, and with UI Elements like Buttons changing the scene works

[languid spire]

show the build settings

[languid spire]

Also, why is there no debugging in your code?

[tulip nimbus]

I originally had Debug.Log codes but i removed them after the rest worked, except for the Scene changing

Putting the SceneManager.LoadSceneAsync("Mainmenu") as the first line in the if statement in the first pic it works, but any other position does not

[languid spire]

then, at a guess, you are getting a null ref exception in the code

put the debugs back and then show the console

[tulip nimbus]

okay so i figured that everything after the second line in AybarsTap() does not work anymore, it also displays this error message. I put the other code into a comment and after the first two, GameOver(); is never called.

What do i have to do to fix this nullRefrence?

[languid spire]

make sure instanceSM is not null

[tulip nimbus]

instanceSM is static, do i just give them any value?

[languid spire]

of course not, I presume you are using the singleton pattern which you should know how it works if you are using it, so I'm guessing you have a script execution order problem

or you are not setting up the singleton pattern in StatsManagerScript correctly

[tulip nimbus]

I see, its probably null and it could be that i didnt set it up correctly. Im not fully aware of all the functionalities since i wanted a quick way to access variables from diffrent scripts so i have to read myself into that more.

This is how i set up my two static instances: instance and instanceSM

public static StatsManagerScript instanceSM;

private void Awake()

{
instanceSM = this
}

And the same for GameManager and instance without the SM

[languid spire]

odd, missing ; there

[tulip nimbus]

there are ofc lines of code between but this is how i did it

[tulip nimbus]

Oops i have that, just forgot to write out

[languid spire]

ok, so you need to debug.log that to see if/when it is being executed

[tulip nimbus]

Running out of time so im going to do that later today and read myself into this topic more. You saying that my instance is null really showed me the problem and now i know what to focus on because this seems to be the issue. Thank you for your time!

[languid spire]

you should never ignore a null ref exception which, I presume, is what you were doing

[dim yew]

getting a null reference exception here. i have no idea why because i have no idea what its trying to access

could this be related to the raycasting i'm doing?

[languid spire]

So, if nothing is hit then MouseHovering().collider will be null

[dim yew]

ahhh thanks

im a bit new to raycasts

[languid spire]

RaycastHit is a struct so cannot be null, collider will only be not null if something is actually hit

[dim yew]

so which is the error coming from?

the collider i assume right

[languid spire]

collider.gameObject. if collider is null gameObject cannot be accessed

[dim yew]

ic

thanks a ton

[neon lynx]

I have some weird error. I have only yellow errors on the console and when I start playing after a while some specific scripts stop working until I press a key that make the player jump, then the specific scripts work again.
So maybe I should fix the yellow errors on the console? Or I should make a new script to solve this particular error?

[slender nymph]

yellow errors
Those are called warnings, not errors. And you need to be more specific about the issue if you want help solving it

[neon lynx]

I noticed something, the specific scripts are related to the tag Ground that's why when the player jumps and collide with the tag Ground the specific scripts work again.

[polar acorn]

You're going to need to actually provide context. Remember, we can't actually see your screen

You're going to need to say what warnings you're getting, what the code looks like, what you're expecting to happen versus what actually is happening, etc.

[languid spire]

have you actually debugged any of this or are you just making assumptions?

[neon lynx]

It's what I've noticed while playing, but I have to debug it. But I think It is possible that the ground collision detection is temporarily failing due to issues with Colliders or with the logic that determines when the player is on the ground. It is surely for that reason that the error happens.
Is there a better way to detect collisions than the OnCollision events?

[languid spire]

go away and debug it properly and when you have come back with more, relevant information

[neon lynx]

Yeah, I will do it.

[turbid robin]

    private IEnumerator Spin()
    {
        float spinDuration = 1f;
        float totalRotation = 360f; 
        float elapsed = 0f;

        while (elapsed < spinDuration)
        {
            float angle = (totalRotation / spinDuration) * Time.deltaTime;
            transform.Rotate(0, angle, 0); 
            elapsed += Time.deltaTime; 
            yield return null; 
        }
        
        transform.Rotate(0, totalRotation - (elapsed / spinDuration * totalRotation), 0);
    }```
when this get called i see the "spin" as an animation of a flip of a page. why? it should be a spin around

[polar acorn]

Because you're rotating it around the Y axis.

You can select the object in the inspector and change the rotation values to see which axis you actually want

[tender breach]

The problem I had was that either clones or child objects can't be detected via collision. Is there anyway I can make it so that they can?

[polar acorn]

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

[tender breach]

That didn't work.

[verbal dome]

The OnCollisionEnter message will be sent to the rigidbody (if it has one) object, not the child collider object

I wish the docs pointed this out..

[polar acorn]

Then you should consider doing it right

[turbid robin]

whit the z axist i get something similar, i think that the error is now the pivot. is it possile?

[polar acorn]

Did you change both rotates

[turbid robin]

because i get the rotation from the bottom left point, i want it to rotate from the center

[polar acorn]

Then yes, you probably need to change the pivot

[tender breach]

https://pastecode.io/s/qjnem61f

That's my code.

AND YES I FORMATTED IT

[tender breach]

Forgot to ping

[turbid robin]

thx i will try

Man, also, there's other error, I think this is more related to Unity, maybe...
Why when I repeat the use (for two enemies for example) of an AudioSource who's in a Gameobject, sometimes it stops playing? Is it always better to have a specific gameobject with the AudioSource for each Gameobject (e.g: enemy) that uses it?

[polar acorn]

Is the object with the AudioSource component on it being destroyed or disabled

[neon lynx]

No. I'm talking about SFX, so it's better for short AudioSources like SFX, that the script momentarily creates the Gameobject with the AudioSource and then when it finishes playing destroy it?

[polar acorn]

When an object is destroyed or deactivated, all AudioSources on it will stop. If you want an AudioSource to play, make sure it is on an object that will continue to exist long enough for the sound to play. Whether that's a separate object or not is a design decision that's entirely up to you

[neon lynx]

Thanks. I think I'll create Gameobjects with the AudioSources for each situation, it's basically the same than the Gameobject with the AudioSource being created then destroyed after playing the AudioSource.

Hey! How could I make a mouse sensivity slider, or atleast 3 buttons for sensivity?

[wintry quarry]

Use a UI slider to set a float variable which you multiply into your mouse input

[fallen mirage]

How can i make a weapon that aims at the mouse?

[cosmic quail]

theres a bunch of tutorials on youtube for that

[fallen mirage]

I cant find any for unity 6

[rich adder]

break down into smaller easy to solve steps.

• Finding mouse world position
• create a direction from target-origin
• assign the rotation / forward to face the direction created

[cosmic quail]

you can watch a tutorial from 2015 and it will likely still work

[rich adder]

yes the API stays the same more or less with a few methods changing names, only be mindful of the js-like syntax ones those aren't valid for c# but the logic is the same

[inland perch]

this is my enemy and i want it to walk like the 6 blocks from the left to the right

[rich adder]

I get the goal

[inland perch]

and that he always keep running forward

[rich adder]

You need to push it with .velocity

use the horizotnal speed on x axis, keep the rb.velocity.y on y axis
eg
horizontalInput = 1 // goes right , -1 goes left
rb.velocity = new Vector2 (horizontalInput * moveSpeed, rb.velocity.y)

later you can add raycast for easy detection of edges

make it kinematic if you don't want player to push it

[inland perch]

[slender nymph]

your input and/or the velocity of the player can be used to "check if the player is moving"

[frosty hound]

You don't need to fuel it @outer wadi, thanks.

[outer wadi]

Okay

[polar acorn]

You could have the platform do a checkbox or some other physics query to see if the player is above them. If they are, check if they're grounded. If that is also true, move the player whenever you move the platform

[prime pier]

ive already got some code for checking if the players grounded. how would i do a physics query?

[polar acorn]

depends on if you're in 2D or 3D

[prime pier]

im in 2d

[polar acorn]

Then probably something like this - https://docs.unity3d.com/ScriptReference/Physics2D.OverlapBox.html

Check if the collider that overlaps a box slightly taller than the height of the platform is a player, and if they're grounded.

[slender nymph]

that code very likely includes a physics query if you're doing it the smart way. physics queries are those methods on the Physics (or Physics2D in your case) class that check for colliders in a given space like Raycast and OverlapBox

in other words they "query" the current state of physics, hence why they are called physics queries

Whats wrong with this Code
I want my weapon to follow the mouse:

The weapon rotates towards the mouse only when it is positioned on the right side of the player

void Update()
{
Vector3 mousePos = Input.mousePosition;

 Debug.Log(mousePos.x);
 Debug.Log(mousePos.y);

 //Vector3 MousePosition2 = new Vector3(mousePos.x, mousePos.y, 0 );

 Vector3 rotation = mousePos - transform.position;

 float rotZ = Mathf.Atan2(rotation.y, rotation.x) * Mathf.Rad2Deg;

 transform.rotation = Quaternion.Euler(0, 0, rotZ);

}

1. !code 👇
2. unless this object that is following the mouse is in screen space, then you need to convert your mouse position from screen space to world space using Camera.ScreenToWorldPoint

also the atan2 is unnecessary, once your mouse position is correct you can just set the object's transform.up (or transform.right depending on its resting rotation) to the direction (which you've named rotation in your code)

[rich adder]

Input.mousePosition is the pixel coordinate of the mouse. It would not make sense to use that in the 3D world

[fallen mirage]

When I use ScreenToWorldPoint, the weapon follows the camera and not the mouse.

[autumn gull]

im pretty new to C# coding and i have this error and idk whats the issue?

what?
also make sure to 0 out the Z or put whatever z position ur sprites are

[slender nymph]

seems like you're trying to use a quaternion in something that expects a Vector3. you need to show relevant code though

[autumn gull]

this is the code that im stuck on

[slender nymph]

start by configuring your !IDE

[eternal falcon]

If your IDE is not autocompleting code

[rich adder]

you probably wanted transform.rotation on line 31

but do configure your IDE asap , this would underline red

The Red thing is the weapon. it follows the camera constantly and not the mouse if i use ScreenToWorldpoint

[rich adder]

show your current new script btw

[autumn gull]

oo im kinda dum

[slender nymph]

is your camera orthographic or perspective

[rich adder]

mousePos.z = 0
try that

[fallen mirage]

perspective

[rich adder]

ahh

thats a problem in 2D

[fallen mirage]

why

[slender nymph]

for future reference, do not ignore information provided to you: #💻┃code-beginner message

[rich adder]

cause of nearClipPlane

[fallen mirage]

sorry

[rich adder]

@slender nymph wait that is because of depth that messes w / z giving not nearCliplane ?

[fallen mirage]

I changed it to this, but it still does not work.

[slender nymph]

i don't know what you are referring to by that. both perspective and orthographic cameras have a near clip plane. their issue is that without providing a depth for the z axis for the position, a perspective camera will always give the camera's position when using ScreenToWorldPoint whereas with an orthographic camera you just need to specify a z position in front of the camera

[slender nymph]

if the object you are rotating is further than the near clip plane then the distance you are using is likely incorrect
why are you using a perspective camera anyway?

[rich adder]

ohh right okay that makes sense . I confused the nearClipPlane with something else 😅

yeah strikes me odd to use Prospective for 2d lol I never used that

2D sprites don't need depth

[fallen mirage]

idk i think that the perspective camera looks better than orthographic

doesnt hollow knight use a perspective camera?

[slender nymph]

define "looks better" because that's subjective but also if you are just using a bunch of flat sprites and don't need depth anyway, then it's also just wrong

[rich adder]

much easier to use plane.raycast then if you really want prospective

but yeah for 2D sprites just weird, it makes more sense 2.5d with some meshes
(gta 2)

[fallen mirage]

it feels like 3D

[slender nymph]

alright. well you've already got your solution on that page i linked earlier so just read it 🤷‍♂️

also that's called depth, because it's all 3d still

[fallen mirage]

my code doesnt work...

i implemented the code that u sent

[slender nymph]

show what you've tried

read the other solutions then

[slender nymph]

you know there's more than just one thing on that page

[slender nymph]

and i already told you why this doesn't work

[fallen mirage]

yeah should i use screenpointtoray?

ok

[slender nymph]

you'll want a plane representing the plane that the object you want to rotate is moving on

[fallen mirage]

i switched to orthopgraphic and changed the code. it works. Thanks for the answers

[runic urchin]

hey, could someone help me figure out whats wrong with this?

[wintry quarry]

just what it says

you can't write arbitrary code like that outside of a method

you can't call randomizer.Next(..) in a field initializer, which is what you're trying to do

int funcToChoose is the field

int myField = blahblah is a field initializer

The error is telling you quite straightforwardly that you can't call a non-static method in a field initializer (.Next(..) is the method in question)

You should put this code in Awake, or Start, or OnEnable

[runic urchin]

oh, i see. thank you so much lol, im new to coding so i didnt know what any of it ment lmaoo

[neon lynx]

Bro, I recently coded that script for my game lol

Ok, in the script, make the platform the parent of the player but only when the player collides with the platform

Use the tag Player to check if the player collides with the platform

Use empty gameobjects for the positions that the platform have to go

Use public Transform PositionA and public Transform PositionB

[runic urchin]

ok, so i have been trying to do different things for the last two hours but i have had no luck with figuring out how i could choose one of these options randomly lol. can anyone help out?

[polar acorn]

Use Random.Range to get a random number, and then use a series of if statements to check if that number is within a specified range

[runic urchin]

alright, lemme try that out

[rocky canyon]

  {
        int randomChoice = Random.Range(0, 4);

        switch (randomChoice)
        {
            case 0:
                MoveDown(ref currentTile);
                break;
            case 1:
                MoveLeft(ref currentTile);
                break;
            case 2:
                MoveRight(ref currentTile);
                break;
            case 3:
                MoveUp(ref currentTile);
                break;
        }
    }```
a switch statement is what'd I use in that situation most likely.

@runic urchin and are u aware u have two MoveLeft functions in ur screen-snip, just curious

[runic urchin]

yeah lol, i just had it there so i would remember which one i wanted a higher chance to happen

[polar acorn]

Switch statement, unless you plan on having non-uniform probabilities. If you want to check if something is, say, between 0-10, 11-50, 51-100, a series of ifs might be better

[rocky canyon]

oh okay.. just making sure wasnt a typo u missed

[runic urchin]

yeah lol, mb

[rocky canyon]

true true.. just figured id throw out the other option since its what first came to mind for me

mediocre coding flex lol

[runic urchin]

i actually tried to use a switch statement earlier but i guess i did it wrong or smth lol

[rocky canyon]

i asked chatgpt too.. it seems to think a list of delegates is a better solution

[polar acorn]

Switch statements only work if every condition is ==

[rocky canyon]

    void Start()
    {
        // Array of movement functions
        MovementFunction[] movements = new MovementFunction[]
        {
            MoveDown,
            MoveLeft,
            MoveRight,
            MoveUp
        };

        // Choose one function randomly and call it
        int randomIndex = Random.Range(0, movements.Length);
        movements[randomIndex](ref currentTile);
    }``` this is the pasta vomit it created

[rocky canyon]

they're a good thing to know if u ever wanna take a shot at them again.

once u write enough if/else chains u tend to see them as a better alternative

[slender nymph]

they could alternatively not make their methods use a reference parameter and instead return the desired tile and use a switch expression which can do pattern matching if they wanted to support ranges and stuff

[rocky canyon]

but ya, ranges and approximations and stuff still better for if else then i guess

Many paths lead to the same destination

thats what i adore about game-dev

[runic urchin]

yeah i cant wait till i learn enough to be able to write my own code for stuff lmao, im at that point where im tasking existing code and stringing it with other stuff to get stuff to work. not that using other code is bad ofc lmao

[rocky canyon]

ur on course then.

that was my 2nd step..

first was wrapping my little brain around coding in general..
then it was robbing and stitching together codebases
and then it was experimenting on my own and creating my own code

here lately.. ive written my own editor scripts to replace the need for NaughtyAttributes.. (thats my peak) lol

for now 😈

[runic urchin]

yeah i have always wanted to make my own game and id always start but give up. now im really trying to work on this one project till the end, that way i can prove to myself that i can actually do this lol

[runic urchin]

the sky is the limit!

[slender nymph]

oh that reminds me, i still need to see if i can figure out how to replace NA's Button attribute for UITK

[rocky canyon]

the best tip i can give you is... decrease ur scope.

keep things smaller than u think u can manage

the last 20% of building a game takes 80% of all the time

[rocky canyon]

i did that exact thing if u care to peek

[slender nymph]

yes, that would be helpful

[frozen plaza]

I have a planet object and a small vehicle.. I put some gravity on the vehicle but the collision doesn't really work, the vehicle just falls into the planet..

It works with a different vehicle, but not with this one.. anyone know why?

[slender nymph]

not really enough info, but at a guess i'd say your collider is a trigger which means no physical collisions

[rocky canyon]

its not elegant but it works..cs [SpawnButton("SPAWN ALPHA")] public void SpawnAlpha() { // spawn a random alpha type. Index between 0 - amount of Alpha types Instantiate(typeAlpha[Random.Range(0, typeAlpha.Length)], transform.position, Quaternion.identity); }
https://paste.myst.rs/ju80tyw2

• SpawnButtonAttribute.cs
• SpawnButtonEditor.cs

@slender nymph sorry, i didnt notice u said UIToolkit until after i started pasting 😭

it is infact not the UIToolkit. but figured u might wanna look anyway.. sorry

works for what i need it for tho..
just SpawnButton[] w/ a boolean for whether its playmode only.. or both editor/play mode

i just wanted to get rid of NaughtyAttributes since i've been seeing editor issues that I can't really pinpoint.. and my most extensive editor manipulations come from NA

[slender nymph]

a lot of issues i've had with NA is due to the custom inspector applied to all MBs to make some of their attributes work. The problem I've run into with making the button attribute work with UITK is doing it without creating a custom inspector for all monobehaviors, but since property drawers don't work for methods that may be the route i have to go

[rocky canyon]

ya, im not too savvy when it comes to reflection.. i looked thru NA's code.. and asked some of my friends to help me get this working.. so far soo good

no performance issues as of yet

the only real issue i have is if i update the buttons while the inspector is open The styles get all messy and colors get inverted or something odd like that

just toggle to collapse and reopen, and the buttons fix themselves

im sure thats a simple fix.. but beyond me for now

[slender nymph]

actually, thinking about it i might be able to use a source generator to only create custom inspectors for the types that actually use the button attribute. i imagine that would end up more convoluted than just a custom inspector for MB, but might at least reduce the number of potential issues caused by the super generalized custom inspector. i'll have to do some tinkering with the two options to see which works better

or see if there is just a better solution than either of those

[rocky canyon]

welp, Unity makes a liar out of me like normally

its probably b/c buttons are already drawn there.. but its usually not this smooth..

[rocky canyon]

soo.. what ur trying to avoid is what im doing correct?

[slender nymph]

yeah pretty much lol

[rocky canyon]

is that what im gathering?

[rocky canyon]

aight just making sure lmao

if u do bite the bullet and build ur own.. HMU if thers anything that could improve mine

i'd greatly appreciate it.. and the learning better alternatives of it all

[rustic maple]

alr imma check it out

[rustic maple]

yeah i mostly get the error: "SetDestination" can only be called on an active agent that has been placed on a NavMesh. but i don’t understand it because it works just fine until the ai is even in a pixel of the camera

[rocky canyon]

typically means ur NavMeshAgent is too far from the MeshSurface to link em

[restive nacelle]

does anyone have any good tutorials for how to make a slot machine in unity, my game takes place in las vegas so i felt it was neccesary to make one

[cosmic dagger]

that's very specific. your best bet is google and youtube . . .

[restive nacelle]

i cant find any

all the ones i can find are from many years ago

I know how to make one in other langauges besides c# but then idk how to implement it

[cosmic dagger]

most tutorials are years+ old. that shouldn't matter . . .

[wintry quarry]

you'd have to start with explaining what your requirements are for this slot machine

at a basic level, it's just a static 3d model

[restive nacelle]

its a 3d game

[cosmic dagger]

did you try it and check if it worked?

[restive nacelle]

2d*

so just a ui really

of a slot machine gui

[polar acorn]

Random.Range three times

[rich adder]

so which part are you struggling with cause its even easier being 2D

[restive nacelle]

thers no tutorials

and this is my first project

[meager gust]

theres tutorials all over the internet for basic unity stuff

[rich adder]

well maybe there are but the trick is never to look for a specific thing , rather break down the problem into smaller and easier to solve ones

[restive nacelle]

so heres what i decided to do now

[rich adder]

same concepts can usually be always applied thorough diff project types

[restive nacelle]

i made a slot mcahine in html

and im wondering how to import that into unity

idk how

[meager gust]

yeahhhhhhh

dont do that. you'll need to redo it in unity. those are two completely different concepts.

[restive nacelle]

especially because like i would have to port variables over

atp im considerign switching to a js framework

[rich adder]

html by itself does nothing useful you mean JS ?

[restive nacelle]

yeah

i made a slot machine in there

with a tutorial

[rich adder]

if you are able to write in JS c# wont be that much different

[restive nacelle]

i used a tutorial i cant do JS on my own

[rich adder]

the concept is the same, esp if you choose a Random like class

[deft grail]

so just do the same thing but in Unity, shouldnt be complicated at all

[restive nacelle]

only language im good at is python

[deft grail]

its all basically the same anyway, the language doesnt matter for basics much

[rich adder]

oh okay well you mind as well learn c# then, its not that much more difficult. if anything JS is harder cause its not statically typed / no compiler telling you if you write something wrong etc.

[restive nacelle]

so learn c# and make my own slot macchine

[rich adder]

start with the basics types, operations, and whatnot. Go on from there
(imo start without a GUI and use console app from .NET )

Hey guys! Is anyone here familiar with Timeline and Playables? I'm trying to create a basic system to write subtitles to a TextMeshProUGUI component, but the API seems to have changed so much over the past 4 years, that I'm not sure how to make heads or tails of it. Here is a sample of my controller that I use to affect changes to the on-screen visuals. How can I control this from Timeline?

{
    public static ClosedCaptions I { get; private set; }
    public static event ClosedCaptionsHandler onNarration;
    public static event ClosedCaptionsHandler onDescribedAudio;

    public delegate void ClosedCaptionsHandler(string source, string text, float duration);

    public NarrationLabelMode narrationLabelMode = NarrationLabelMode.Header;
    public enum NarrationLabelMode
    {
        Header,
        Inline,
        InlineCapitalized
    }

    private void Awake()
    {
        I ??= this;
    }

    public void Narration(string source, string text, float duration)
    {
        switch (narrationLabelMode)
        {
            case NarrationLabelMode.Header:
                onNarration?.Invoke(source, text, duration);
                break;

            case NarrationLabelMode.Inline:
                onNarration?.Invoke(null, $"[{source}] {text}", duration);
                break;

            case NarrationLabelMode.InlineCapitalized:
                onNarration?.Invoke(null, $"[{source.ToUpper()}] {text}", duration);
                break;
        }
    }
}```

[rich adder]

not sure too much about Timeline but if you want to run code you need signals
https://youtu.be/fQzKJO-0dS8
https://youtu.be/X4Mbk54XqNk this guy has good videos on playables btw

[wicked pulsar]

Okay, I did come across that, along with some outdated tutorials that never made use of signals. Are signals a relatively new thing?

[rich adder]

as far as I know signals have been around since timeline 2019 if not sooner, not sure I got into unity late 2020

[wicked pulsar]

Okay, thanks a lot!

[rich adder]

https://unity.com/blog/engine-platform/how-to-use-timeline-signals

[wicked pulsar]

We’ve built Signals to establish a communication channel between Timeline and outside systems. But what does that mean? Why did we decide on this approach?
Sounds like this is what I needed. Thanks!

[rich adder]

also in the docs they have more stuff https://docs.unity3d.com/Packages/com.unity.timeline@1.8/manual/wf-signals.html

[queen adder]

Can 2D physics queries (circles) be rotated so that it lays flat in the XZ plane?

[rich adder]

dont think so because 2D colliders are only XY

[wicked pulsar]

No; the 2D physics system only lives in XY and ignores the Z plane. If your game has no use for physics depth, it should be built in XY, otherwise, a lot of people choose to use the 3D physics system for 2.5D games. There is no way to use the 2D physics system at any angle outside of Y being up and X being right.

[cosmic dagger]

nope, that's essentially using 3d physics . . .

[primal flare]

[limber remnant]

I was wondering if someone could help me with something. So I am using cinemachine to create a dolly track and Camera. I then want to move the camera to each of the way points by a button press. But for some reason I can't seem to get it to work properly. I think the code itself should work but when I go to attach the dolly track it just won't let me do it. And only keep saying that there's none available.

[wintry quarry]

What are you actually trying to drag in there

The track wouldn't go there

A dolly would

[queen adder]

Does unity support multi language ? For example, can "using UnityEngine" instead be written in japanese ?

or it is strict latin and english ?

[short hazel]

C# has English keywords, and the base library is in English, but you're free to name variables in your own language.

[queen adder]

Okay thank you

[queen adder]

does "base library" include unity library ? (UnityEngine, Unity, UnityEditor, etc)

[short hazel]

Yes

[queen adder]

Okay thanks

[limber remnant]

I guess I am confused on how to create a dolly then. There's no option for that as far as I can see. Just create the camera and track or create track and cart

Because I tried to putting the camera in there which is a dolly camera but that didn't work

[static cedar]

[ExecuteInEditMode]
public class InvertMaskingImage : UIBehaviour, IMaterialModifier
{
    [NonSerialized] private MaskableGraphic? graphic;
    private MaskableGraphic? CheckedGraphic

        {
            if (graphic == null) graphic = GetComponent<MaskableGraphic>();
            return graphic;
        }
    }

    public Material GetModifiedMaterial(Material baseMaterial)
    {
        if (CheckedGraphic == null) return baseMaterial;
        if (CheckedGraphic is MaskableGraphic image && !image.maskable) return baseMaterial;

        int id = baseMaterial.GetInstanceID();
        if (id >= 0)
        {
            Debug.LogError("Material is not an instance. Gonna oof ur project if this continues. Not bothering to copy either.");
            return baseMaterial;
        }

        if (isActiveAndEnabled) baseMaterial.SetFloat("_StencilComp", (float)CompareFunction.NotEqual);
        else baseMaterial.SetFloat("_StencilComp", (float)CompareFunction.Equal);
        return baseMaterial;
    }

    protected override void OnEnable() => CheckedGraphic?.SetMaterialDirty();
    protected override void OnDisable() => CheckedGraphic?.SetMaterialDirty();
}

Am i playing with fire with this script?
I'm asking if this is enough checks so as to not inadvertently make the entirety of ui invisible.

What i really wanna check if the parent is a Mask and it's active.

So it's more decently full proof.

[autumn gull]

how do i fix?
MissingComponentException: There is no 'Animator' attached to the "Player" game object, but a script is trying to access it.
You probably need to add a Animator to the game object "Player". Or your script needs to check if the component is attached before using it.

[keen dew]

You probably need to add a Animator to the game object "Player"

[autumn gull]

ye i know that but then the player anims dont work so im thinking how do i access the actual playermodel that has the animator

[autumn gull]

so it works then

but im not sure how

[keen dew]

Remove the getcomponent call, use [SerializeField] private Animator animator; instead and drag the animator you want into the field in the inspector

[autumn gull]

i didnt understand the end, wdym by that?

[autumn gull]

i have it like this

[keen dew]

Right, drag that object into the field

[autumn gull]

the player model?

[keen dew]

Yes, the one that has the animator you want to use

[autumn gull]

ok i did that

but it gives me an error

[autumn gull]

Assets\Scripts\PlayerController.cs(19,26): error CS0106: The modifier 'private' is not valid for this item

[keen dew]

You put it in the wrong place

[autumn gull]

i replaced animator = GetComponent<Animator>(); with the thing u told me

[keen dew]

No, replace line 14 with it. Delete line 19

[autumn gull]

oohh mb bro

[autumn gull]

now it works but do u know why it stops the animations in place?

its on loop time

ok i made run work somehow

[frozen plaza]

when I save my file, unity reloads the domain. when I then enter play mode it reloads again.. can I change this so it does not refresh on save but only on window activation (and going straight into play mode with one reload if possible)?

[teal viper]

Disable auto refresh. Though you'll still need to refresh manually before going into play mode.

Also, you can disable domain and scene reload on play in the editor preferences(or was it project settings🤔)

[frozen plaza]

I think at some point I enabled it to refresh on save but now with more stuff going on that really slows down iteration times

I need it to refresh before going into play ofc and also when activating the window in case some changes in editor space happened

[teal viper]

You can't have both. Either you refresh manually, or let unity refresh whenever an asset file is updated(like a script change saved).

[frozen plaza]

unfortunate.. but ok, thanks

[verbal dome]

You could maybe write an editor script that recompiles scripts when entering playmode, though.

[frozen plaza]

yea, been thinking about ways to make this happen but at this point in time I don't want to spend too much effort in setting up dev environment when the time save isn't significant enough

[astral falcon]

I guess, making your own play button would be the most simple solution

i can show the code in dms

Is it possible to load new scene at runtime without building it to assetbundle ? I mean load the new scene from .unity file at runtime

[autumn gull]

but i dont want to get rid of mine i want to add the jum into it

ok? No one suggested to get rid of yours..

Watch the video and learn how they did jump.. then use that information to add it to yours...

[cedar prairie]

Whenever my object collides with another object it then starts moving in a random direction forever and i dont know why

[verbal dome]

How are you moving the object?

[silk night]

What i think happens:

• Rigidbody is dynamic
• Either no gravity or a physics material without drag which could stop your object

[cedar prairie]

With transform.translate

[verbal dome]

I'm assuming you have a rigidbody?

[cedar prairie]

Yeah

Ik its the rigid body doin it

[verbal dome]

This is why you should not use transform to move a RB

Use rb.velocity/AddForce instead

[cedar prairie]

I tried using addForce but it just fucks me because it wont stop unless i do an opposite force and it sucks

[verbal dome]

Like Sidia said, if there's no external forces (drag, gravity, friction) then it will indeed keep moving "forever"

[silk night]

is it sliding across a floor or are you "in space"?

[cedar prairie]

In space

[cedar prairie]

So just do addforce but add drag?

[silk night]

then why would it slow down? if you throw something in space it wont stop either 😄

[cedar prairie]

Well not literally in space just in the air

[wintry quarry]

Welcome to how physics works 😁

[verbal dome]

Sure, although I also mentioned rb.velocity

[cedar prairie]

Gah

[verbal dome]

You could directly edit the velocity if you want precise movement

[night valve]

Afaik it will... Eventually ;p

[silk night]

Simulating air drag is not just a checkbox sadly, you will have to write a script that slows objects

[cedar prairie]

Whats the difference between that n regular rb.addforce ?

[verbal dome]

Hmm? There's rigidbody.drag

[verbal dome]

Basically AddForce just adds to the velocity

[silk night]

yeah when it hits the next object 😄 Rabbithole incoming

[silk night]

Uhh oops, not sure what i thought of then

[verbal dome]

Brainfart 🤷‍♂️

@cedar prairie If you want you can manually set the velocity in each FixedUpdate

Or just use AddForce if that suits you better

[cedar prairie]

Gah

Thanks for the help btw,

Oh wait so insted of add force its rb.velocity?

[night valve]

There is some super tiny million times thinner than air drag in space, but I'm picking on just for the sake, nvm

[verbal dome]

What are you asking? velocity and AddForce are different things

velocity is a Vector3 (or Vector2 in 2D) property and AddForce is a method

[cedar prairie]

Right, but does velocity work in the same way as AddForce?

[verbal dome]

No

I mean you can use either one to move the rigidbody, so in that sense yeah

[limber remnant]

That's what I thought as well. But for whatever reason it's not letting me put the cart in there. So I wasn't sure if there's some sort of setting I need to do or something.

[silk night]

if you set velocity you just override its speed, if you add a force it takes current movement into account

[cedar prairie]

Right so since im utilizing the camera for its movement ill prolly want AddForce

[silk night]

uhh ok now might be the time you describe what you are trying to do, this got way too confusing with just a general problem description 😄

[cedar prairie]

So right its a little space ship thats floating at a set/locked Y coord. Im makin a game that's based around destruction n like physics so i might move the ship through other objects. Its supposed to be moved with w,a,s,d but the camera controlls the direction forwards is

[silk night]

ok then you have multiple possibilities:

• Make the ship kinematic and move it on FixedUpdate loop, that way other objects cant move your ship
• Add a drag or script way to slowly break from any collision events
• Let the user figure out how to recover from a collision via controls

if you just want to break your other objects in the scene the drag option should be sufficient

[cedar prairie]

Oh thanks

Yah ill prolly try em n see what i prefer thanks for the help

[queen adder]

im trying to save some data to a json object. the structure looks something like..

public class savedata { 
//save info here
public scriptableobject referenceToSOHere;
}

the problem however, is that the scriptable object holds a reference to a prefab and throws the following error
JsonSerializationException: Self referencing loop detected for property 'gameObject' with type 'UnityEngine.GameObject'.

what would be the best way to prevent this from happening?

[wintry quarry]

Serializing a ScriptableObject directly is not advised

you either need to:

• Make a custom serializer for your SO
• Serialize some kind of identifier you can use to look up the SO instead

It's also not clear which serialization framework you're using here. Newtonsoft?

[queen adder]

yeah newtonsoft in this case

[wintry quarry]

You need to carefully think about what your intention is here. Presumably your ScriptableObject is an asset in the project right? So even if you properly manage to serialize it to JSON, you're not going to have that actual reference back when you deserialize

[queen adder]

yeah im storing general stat related information of an item in the scriptableobject, so things like, name, description, icon, stats of that item, and then the prefab directly related to it.

[wintry quarry]

right so - is the SO something that changes over the course of the game? Or is it basically a reference object that contains unchanging data

[queen adder]

unchanged data.

[wintry quarry]

if it's the former, you will want to fully serialize it here.
If the latter, you will want to serialize only a reference to it

[queen adder]

the refrence to the save data will change over the course of the game, but the data inside of the so is static and never changes.

[wintry quarry]

You could either use the Addressables package, or index them by some kind of ID so you can look them up yourself

and then basically your JSON should contain only that identifier

[queen adder]

addressable package isnt something i have used before, but based on looking it up, is it basically a database of assets, and instead of referencing the scriptable object, in my case, i would instead use an assetreference which can be serialized?

[wintry quarry]

In a nutshell, yes.

[queen adder]

i'll take a peak and see if i can easily change how things are loaded/saved/referenced.

thanks

[wintry quarry]

You might need something like this btw, to convince newtonsoft to work with Addressables properly: https://www.reddit.com/r/Unity3D/comments/l3saxh/comment/gkixwhq/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

[queen adder]

yeah i see that, sadly not as simple as i was hoping.

[rancid tinsel]

whats this about?

am i being stupid and its not TMPro?

[polar acorn]

Do you have the package installed

[burnt vapor]

Are you using assembly definitions?

[polar acorn]

and is this an error in Unity or just in the IDE?

[rancid tinsel]

oh yes i am

[burnt vapor]

Make sure to reference TMP as a dependency, then it works

[rancid tinsel]

i have it set up for unit testing, would that be a dependency in the script folder one?

so here?

[burnt vapor]

Sorry, haven't used Unity in a while

TextMeshPro should have an assembly definition of its own. Drag its reference into your assembly definition

[rancid tinsel]

yeah that fixed it

thank you!

[dim yew]

unsure why the ray is still getting the layout object here. i tried to mask it out and it doesn't seem to work

raycasts are really causing me issue right now

[polar acorn]

Why shouldn't it? It looks like it does have the layer you're looking for

[stiff birch]

Your mask should exclude layout if you want to ignore this layer

[dim yew]

ok i am VERY misinformed on layermasks then

apologies

[polar acorn]

Yes, those are the layers you want to interact with

[dim yew]

is there an easy way to do that? or shoudl i read up on them

[stiff birch]

I suppose you can read this https://docs.unity3d.com/Manual/use-layers.html

Does not say much. LayerMask are the layers you actually care about.

[dim yew]

thanks a bunch

[rancid tinsel]

is there a way to find a gameobject by its transform position?

[polar acorn]

Does it have a collider?

[rancid tinsel]

yes a box collider

[polar acorn]

Do an OverlapSphere at that area, with as much radius as you want to account for "fuzziness" in the position (it'll almost never be exactly at the location you expect due to floating point shenanigans)

https://docs.unity3d.com/ScriptReference/Physics.OverlapSphere.html

[rancid tinsel]

how would this work though, like if it hits multiple colliders how would i know which is which

[polar acorn]

Which one do you want

[rancid tinsel]

im making a mine sweeper clone, so i want to check the 8 colliders around a block

but im prob doing it super inefficiently

[polar acorn]

In that case, you should have an array or grid instead, and then just get the objects at the bordering coordinates

position should not be a factor here

[slender nymph]

#🤖┃ai-navigation

[rugged gulch]

my bad

[queen adder]

was looking into this a bit more, but, how unsafe would it be to do the following? the saving would happen maybe once every X min and the loading would really only happen when triggered by the player. at max i would assume the player would be loading around 20~ assets on load, give or take.

public void LoadData() {
        string json = SaveAndLoadUtil.LoadJson(DATA_FILENAME);
        if (json == "") {
            return;
        }
        data = SaveAndLoadUtil.LoadObject<Data>(json);
        data.scriptableObject= AssetDatabase.LoadAssetAtPath<ScriptableObject>(data.scriptableObjectPath);
    }

    [Button]
    public void SaveData() {
        data.scriptableObjectPath = AssetDatabase.GetAssetPath(data.scriptableObject);
        SaveAndLoadUtil.SaveJson(DATA_FILENAME, data);
    }

[wintry quarry]

Yeah this is more or less the idea.

[queen adder]

cool, ill just go this route then. the addressables sound cool in theory but im just unfamiliar with them/cant figure out how to do it in a simple way without having to recode a bunch of extra stuff.

[slender nymph]

I would recommend using string.IsNullOrWhiteSpace rather than checking if the string is equal to ""

[queen adder]

thats valid i just had it there as a simple check when testing and was planning on moving over to that

and then in my data object i'm also using [JsonIgnore] on the actual references to the scriptable object.

and doing [HideInInspector] for the paths.

[rustic maple]

how does that come when the ai is always walking on my terrain?

it only gives the error when the ai is in a frame of the camera

[queen adder]

oh, a problem with this, is if i change the asset location in the future, and push an update for my game, then save files break... so, this wont work...

[slender nymph]

wait was that supposed to be for runtime? because the AssetDatabase does not exist in a build

[languid spire]

wouldn't work anyway, AssetDatabase is editor only code

[queen adder]

ah, well then, time to find a new altenrative/look into addressables again then

[tulip nimbus]

So this is kind of confusing me. My code works perfectly FINE, however i constantly keep getting this null reference message that i just cannot fix nor do i know what causes this, since the code runs perfectly fine and returns all values flawlessly

[wintry quarry]

most likely you have an extra copy of whatever script this is in the scene where that reference is not populated

[tulip nimbus]

That was quick! Thank you

found it and fixed it!

[sleek notch]

Hi, I'm sending messages between scripts and it is giving me an error: nameOfItem has no receiver. But as you can see, there is string. Can someone helo me?

[wintry quarry]

I'm sending messages between scripts
How?

[wintry quarry]

Why are you using SendMessage

why not just call the function

.GetChild(...).GetComponent<MyScript>().nameOfItem(itemName)

[wintry quarry]

anyway if you're getting that error here, the logical conclusion is that the child you're getting doesn't have that script attached to it

[sleek notch]

oh

[polar acorn]

That would mean there's no script on that object that has a function called nameOfItem. One of the reasons you shouldn't use SendMessage, it has no compile-time checking of this

[sleek notch]

well

Actually I do

[polar acorn]

Not according to that error you don't

[sleek notch]

But nvm I can try this method thanks

[sleek notch]

I do. Really I do. I checked it more than 5 times

[polar acorn]

Errors don't lie. The last child of inventoryCollumTransform does not have any components with a function named nameOfItem on them at the time this line runs.

[sleek notch]

I don't lie. I have everything linked right. The Transform is linked right and then I Instantiate the object that really has the script where is the reference

I can give you screenshots

[polar acorn]

When the options are either a human mistake or a machine mistake, it is 100% the human's fault

[sleek notch]

Okay. I'm gonna give you all screenshots

So. First is name of the script, second is where it is spawned and as you can see there is transform and third is linked script in the object that is being spawned

[polar acorn]

Take a screenshot of the full Unity window, after the error occurs, with the final child of RightPanelPlayerInv selected

[polar acorn]

This doesn't have itemPanel(clone) selected

[sleek notch]

wdym?

[polar acorn]

I said to select the last child of RightPanelPlayerInv

[polar acorn]

Show the full !code of inventoryItemManagement (can also take a look at that null reference while we're at it)

[amber nimbus]

Hello, unity suggests this design pattern in one of their blogs. Now I am wondering how do I actually implement this? My only idea would be using a ton of events for each of the systems I make. I am not sure if this is a good idea or if I should stay away from making my whole code structure event based.

[polar acorn]

You would have a Player object with Components that each do one individual thing, rather than a monolithic "everything" script for the player

So, you would have an Input component that passes data to Movement, so now you can re-use that Movement script for things that aren't the player by changing which things call which functions

[sleek notch]

https://paste.ofcode.org/QZk8qddQMP3ZXkLC9ypwTv

[polar acorn]

Okay, so your NRE is that there is no TextMeshProUGUI component on whatever object itemName is assigned to.

How are you calling nameOfItem now since the update? Share the code of that script as well.

[amber nimbus]

Yes, this is what I do already, but this image suggests having it even more modular, my normal approach would be a PlayerMovement script, a PlayerCamera script and so on. But this suggests I have Input and Movement handled in their own class. I am not sure if I am taking this picture too literally.

[polar acorn]

What you've just described you're doing and what you've said it suggests you do are the same thing.

Scripts contain classes

[sleek notch]

since that I have changed the code so I'm not already using sendMessage. I'll paste you the segment that you need to see

[polar acorn]

Yeah, let me see it and I can devise a log of some sort to show why the send message failed. It's also possible that the NRE was causing the function to abort and thus not completing the message call

[sleek notch]

https://paste.ofcode.org/3RssRPEf8KhcyBRyHYe7fU

[polar acorn]

Ah, you're calling it immediately after spawning it. Start hasn't run yet

item hasn't been set

(Also if you're trying to call a function on the thing you just made, you should just use that object instead of getting the last child of the column)

[amber nimbus]

yeah i understand, but my PlayerMovement would have an if statement that checks an Input and if the input exists it would handle how the player should move. But I thought this picture wanted me to have a separate Input class and a separate Movement class meaning I would have the Input class fire events and the other classes subscribe to them I just dont know how events are performance wise, and if it is good pracitce to have a tone of events

[sleek notch]

I'm sorry I'm just tired this day. I don't understand this section

can you describe it more?

[polar acorn]

Instantiate returns a reference to the object it just created. Call the function on that and skip the Getchild

[polar acorn]

If you have different scripts for input movement, they are different classes. This diagram is suggesting you have different components for Audio, Input, and Movement.

[polar acorn]

Also why make a public GameObject that exists entirely to get a TextMeshProUGUI from instead of just making the TextMeshProUGUI public and assigning that

[sleek notch]

Because there are more gameobjects for name or for kgs

so I need reference the name

[sleek notch]

Do you mean this?

[polar acorn]

Right now, if you deleted the public GameObject itemName and made the TextMeshProUGUI item field public, it would do the exact same thing

[polar acorn]

If you are instantiating something solely to get a component from it, make the variable referencing the prefab of that type. Then Instantiate will return a reference to that component directly.

Basically, there's almost never a reason to have a variable of type GameObject. Use the type you actually want

[sleek notch]

the exact error still

wait

probably my bad

[polar acorn]

itemCollum should be of type inventoryItemManagement. Not GameObject.

And you'll want to assign it's item variable directly

[sleek notch]

There is something wrong with TextMeshPro reference

or idk what is wrong. It will find the script but something went wrong...

[rich adder]

whatever component you tried using at line 26 its missing

[rancid tinsel]

does this essentially mean it works like a singleton but for a variable/function?

or am i misunderstanding it

[short hazel]

It's a bit less permissive than public. So if you declare something that's internal, other assemblies (= projects, DLLs when compiled) will not be able to access or use the thing

From least to most restrictive in order: public, internal, protected, private

[rancid tinsel]

im not sure i understand then

this might be a bad example but would cheatengine not be able to access internal, but could access public?

i know it reads memory but just for the sake of the example

[languid spire]

generally if you are using Unity then Internal is of no consequence as all Types will be inside the same dll

[short hazel]

CE works at a lower level so it's not really a good example here

[rancid tinsel]

i guess instead of cheatengine substitute just any external program

[short hazel]

If you used C# out of Unity, you may have created multiple projects in a single VS solution, each of them will be compiled to their own assembly

[rancid tinsel]

oh and those cant communicate between eachother if internal?

but could communicate if public?

[short hazel]

Something declared as internal in project A cannot be accessed from project B.

[strong wren]

Access modifiers are for programmers and don't bring memory protections. Even programmers within a project can bypass access modifiers if they really want to.

[rancid tinsel]

i see

so i guess maybe a better comparison would be that its like protected but instead of the inheritance hierarchy, its like a project hierarchy?

[short hazel]

Yep

You may use it without knowing btw, when you create types (classes, structs, etc.) that don't have any access modifiers eg. class Sample { }, they're internal by default.

[rancid tinsel]

oh interesting i had no idea

[short hazel]

Like members without any mods are considered private

[rancid tinsel]

i was curious how that was handled actually because i assumed it would throw an error

[short hazel]

It's purely compile-time verifications. With Reflection you can access stuff that you're not meant to anyway

[gusty cave]

Hello. I'd like to make my game have different behavior when button V is pressed and when it is not.
The problem is that I don't know how to get the value of the button, as what I'm using bellow does not work.

private void OnFreeCameraPerformed(InputAction.CallbackContext context)
{
    bool buttonValue = context.ReadValue<bool>();
}

[wintry quarry]

bool buttonValue = context.ReadValueAsButton();```

however - depending on how you assigned thawt listener to the action - it may always be true.

like if you did freeCameraAction.performed += OnFreeCameraPerformed;

in that case you could also do:

freeCameraAction.canceled += OnFreeCameraPerformed;``` and it should work properly.
Or just write separate listeners:
```cs
freeCameraAction.started += _ => buttonValue  = true;
freeCameraAction.canceled += _ => buttonValue  = false;```

p.s. #🖱️┃input-system exists for further questions.

[gusty cave]

Thank you.

[rustic maple]

does anyone know the issue of this happening with my ai? i didnt make anything about the ai to stop when looking at it, it just happens through error, and it also happens when the ai is on the other side of the map

[wintry quarry]

shwo the full stack trace of the error

[steep rose]

are you trying to set a destination outside of the current navmesh?

[rustic maple]

it only sais this the seconds you look at the ai

[wintry quarry]

you need to click on one of those

it will show the full error message at the bottom

[rustic maple]

okay one se

and this is the script it refferences too:

[wintry quarry]

Please use a paste site 🙏

[rustic maple]

yep i know

was doing it

https://paste.ofcode.org/asapE9CLFUmvQj7at9FDQQ

[languid spire]

now read the message and read this

ai.enabled = false; //Slender's Nav Mesh Agent component will be disabled
            ai.speed = 0; //Slender's speed will equal to 0
            ai.SetDestination(transform.position);

[wintry quarry]

            ai.enabled = false; //Slender's Nav Mesh Agent component will be disabled
            ai.speed = 0; //Slender's speed will equal to 0
            ai.SetDestination(transform.position);```

seems pretty clear

yeah

you're disabling the agent here

[rustic maple]

ohhhh

why tho? because i got this script from a tutorial i was following

[wintry quarry]

why what

How should we know why your random tutorial script is doing something 🤷‍♂️

they must have made a mistake

[rustic maple]

why in the script the agent needs to be disabled

[rustic maple]

lol youre right

so change the false vallue to true?

and the speed to 1

[languid spire]

just remove the line

[wintry quarry]

maybe?
Maybe double check your tutorial and make sure you copied it properl;y

or check the comments on the youtube video

people will have run into the same problem and fixed it.

[rustic maple]

alright ill let ya know

[rustic maple]

the 3 of them in your screenshot or just the first one?

[languid spire]

omg. please engage your brain. the setting to false is causing the problem so that is the line to remove
