Does that look like this?
#💻┃code-beginner message

What is the difference between mine and yours?

[mossy arrow]

huh?

[mossy arrow]

hmmm

this

[slender nymph]

something is missing

there you go

[mossy arrow]

got it gang

so like im a pro now?

[slender nymph]

you should really consider going through some beginner courses to learn wtf you are doing. Debug.Log should have been like the first line you wrote in unity

[mossy arrow]

why is no one talking

[elfin eagle]

only one u need is unity junior programmer pathway

[mossy arrow]

whats that*

[summer stump]

Is there a question? You have the tools. You used them. Now try more

[slender nymph]

disagree. learning the basics of c# first then doing the junior programmer pathway is a better idea. you'll get a better grasp of what is going on when you actually get to writing unity code

[mossy arrow]

ok so i dont see my gave over screen

[mossy arrow]

i did do the basics nothing said something about debug

[shell sorrel]

if you missed that, you did not follow the basics

[summer stump]

So use debug more...

[mossy arrow]

ok

[shell sorrel]

learning about debug or print call for any langauge is like first 10 mins of learning shit

[slender nymph]

somehow i doubt that

[mossy arrow]

ask me something

[slender nymph]

no, i'm just going to block you since you clearly don't know wtf you are doing and you refuse to actually take the time to learn

[swift crag]

how about you stop wasting our time and go learn the fundamentals of programming

it's really not that much to learn, but you really do need to put in some amount of effort on your own

[mossy arrow]

then what the fuck im i doing.

there we fixed it

[heady nimbus]

I should probably just look at this more tomorrow when I'm not so tired but I can't get this enemy to reverse direction when it hits a wall. It does it when it finds the end of the platform, but then just slams into the wall and stops... It's probably something very stupid...

https://hatebin.com/avifwbymtr

[summer stump]

You're doing else if

So it it is grounded, it never evaluates the wallcheck

Also, looks like you do two wallchecks, but the first isn't actually used?

[heady nimbus]

Ah yea shit the first was to make sure the gizmo was actually drawing correctly, forgot to take it out..

[round scaffold]

this is gonna sound real dumb

but i have an interaction system that calls a function on an object when its close enough

is there a way to let that object know what called its interact function?

[shell sorrel]

make the first arg of the function be the calling object

then when you call it just pass a this reference

[round scaffold]

wack

thank u mr knight with horns

[copper perch]

Can anyone help me with my ammo pick up for my fps game.
The ammo pick up script below is not working with the UI script and the Player Manager script.

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

public class AmmoPickUp : MonoBehaviour
{
    public AudioSource pickupSound;
    public int ammoToAdd = 20; // Number of bullets to add when picking up one clip
    public string ammoType = "DualGlock"; // Type of ammunition (can be "Pistol", "Shotgun", etc.)

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            // Play the pickup sound
            pickupSound.Play();

            // Update the player's ammunition count based on the ammo type
            PlayerManager.Instance.AddAmmo(ammoType, ammoToAdd);

            // Add bullets to the total bullets count
            PlayerManager.Instance.totalBullets += ammoToAdd;

            // Destroy the ammo pickup object
            Destroy(gameObject);
        }
    }
}```

[heady nimbus]

Ok so I think it's a problem with the way I'm reversing direction because if I put a wall in front of the enemy, it WILL reverse off that, but will not reverse again

[rich adder]

what is nor working exactly

put a debug.log inside the trigger

[slender nymph]

be more specific than "not working"

[rich adder]

i smell gpt 😮

[slender nymph]

yeah there's a lot of unnecessary comments here

[rich adder]

// Destroy the ammo pickup object Destroy(gameObject);

haha no shit gpt

[round scaffold]

whats the error

Assets\Inventory system\Scripts\InventoryContainer.cs(13,25): error CS0246: The type or namespace name 'GroundItem' could not be found (are you missing a using directive or an assembly reference?)

am i missing some kind of reference?

[slender nymph]

do you have a type called GroundItem

[round scaffold]

yea

[slender nymph]

where

[round scaffold]

its just this

[rich adder]

huh..

they must be in two different assemblies or something

[slender nymph]

it doesn't look like it, but just to be sure is that class in a namespace?

[cosmic dagger]

are the scripts inside of a namespace?

[round scaffold]

i dont think so

my inventory script is inside an assembly

is that the problem

[queen adder]

Try recompiling...

[cosmic dagger]

do the class name and the file name for GroundItem the same?

[north kiln]

You'll have to elaborate, as every bit of code is in an assembly

[queen adder]

It can sometimes be that.

[slender nymph]

yes, that assembly will need to reference the assmebly the other type is in

[cosmic dagger]

did you save the GroundItem file?

[north kiln]

Do you mean under an assembly definition?

[lean grove]

Wrapping all your code in a specific namespace schema will do wonders

[cosmic dagger]

oh, just read the assembly comment. that's most likely it . . .

[round scaffold]

alrighty lemme try lol

[ashen ferry]

I want to instantiate/destroy some prefabs while in edit mode I didnt try anything yet but whats the idea would execute always attribute suffice or not

[rich adder]

its so annoying we can't even use scoped namespaces bruh

[lean grove]

One day…

[slender nymph]

hopefully sometime next year 🤞

[lean grove]

Or the next

[queen adder]

Have you tried regenerating the project files?

[round scaffold]

how i do that just opening and closing it?

[slender nymph]

that's not going to magically make one assembly have a reference to another

[rich adder]

if you're using assembly defintions make sure you include the correct one

[queen adder]

Go to Preferences - External Tools, and you'll see a button that says "Regenerate project files".

[queen adder]

Yep. If different assemblies then it likely wouldn't work.

[heady nimbus]

Is Quaternion.Euler "amount to rotate" or "set rotation to"?

[rich adder]

Euler just turns vector3 into Quaternion no?

[slender nymph]

neither, it just makes a quaternion from euler angles. the angles you supply and how you use it is what determines whether it is amount to rotate or the desired rotation

[cosmic dagger]

https://docs.unity3d.com/ScriptReference/Quaternion.Euler.html

[queen adder]

I got a question about custom inspector script. Is it viable to post it here or in code-advanced?

[rich adder]

prob #↕️┃editor-extensions

[heady nimbus]

Ok so I'm not using it correctly then. What would I want to use as an "amount to rotate"

[shell sorrel]

also i tend to avoid Euler where i can, oftne better ways to do things

[queen adder]

Thanks.

[round scaffold]

i decided just delete all my assemblies and take the headache later when the project actually gets big enough to care

cant hve problems when u erase them from thier virtual existenc

[cosmic dagger]

once you create an assembly, all of your scripts have to use an assembly definition . . .

[rich adder]

yeah compartmentalized af in the beginning . Overkill

[shell sorrel]

really would avoid them unless you have a reason to isolate certain things

and want to ensure a system is easy to move between projects

[cosmic dagger]

i mainly do this, or at least, try to . . .

[shell sorrel]

even in a very large project at work, we only have a handful of extra asmdefs or precompiled assemblies in use

and that is mostly for things we use more like a library

[heady nimbus]

Nevermind, I'll just flip localScale, that seems easier for now. Lol. But yay! It's working

[shell sorrel]

yeah for that, also a precompiled assembly that has types used by client and some logic on our server

[cosmic dagger]

see, that sounds cool . . .

[shell sorrel]

our behaviour system has one too, since it was useful being able to use internal to properly encapsulate things

[cosmic dagger]

that's what i need to start doing: change my classes to internal from public . . .

[worthy veldt]

i used OnPointer events for my buttons, and now i want to display item information UI when mouse is hovering over item slot.

even though this preview UI is set to ignore raycast, this new instantiated UI is obstructing and thus executing OnPointerExit. how do i make it behave like it doesnt exist or do i have to change and write raycasts from scratch

[upper spire]

how can i get the material of the face a raycasthit variable hit?

[queen adder]

how to make this Task class nullable, but still visible in the inspector? I cant null it since the class is serilized

[wintry quarry]

Disable raycast target on the Image or any graphics in it

[queen adder]

[Serializable]
public class Task
{
    public int priority;
    public Vector3 position;
    public Skills required;

    public Task(int priority, Vector3 position, Skills required)
    {
        this.priority = priority;
        this.position = position;
        this.required = required;
    }
}```

[worthy veldt]

i did

[wintry quarry]

Unity serialization doesn't support null.
Use a bool and naughyyAttributes to hide it

[north kiln]

You can't, especially not in your Unity version

[cosmic dagger]

i assume the buttons are the item slot? if so make sure raycast are ignored for the instantiated object . . .

[wintry quarry]

Show

[worthy veldt]

sec

[wintry quarry]

Because what I'm talking about is not the Ignore Raycast layer.

Which Is what your original comment seemed to imply

[cosmic dagger]

use an empty ctor that sets defaults for all of its fields . . .

[wintry quarry]

Any child objects of this?

[lean grove]

I'm not sure you can. raycasts hit colliders, not materials, so unless each face has a separate collider, I think you can only get the one material.

[upper spire]

im sure its possible, ive seen forum posts but i cant get it to work myself

something about a triangleindex

[wintry quarry]

RaycastHit has info about the triangle it hit for MeshColliders

[lean grove]

You could maybe get UV info and map it out from there, but that's not something I have experience in

[upper spire]

how do i get the material of the triangle in that case?

[wintry quarry]

You'd have to examine the mesh and see which submesh that triangle is in

Does your object actually have multiple materials?

[upper spire]

yeah

[wintry quarry]

Then yeah see which submesh the triangle is in

[worthy veldt]

no i set all object of this preview UI like this, you can try it yourself, this onpointer events doesnt seem to behave in line with Raycast.

[wintry quarry]

Works fine for me...

[upper spire]

how do i do that? sorry i havent done much with meshes before now.

[worthy veldt]

owh, really. i had to write my own raycast before just to finish the job

i'd love to know whats wrong this. ill check again

[wintry quarry]

Check which object your event system is actually seeing in the preview window

Disable raycast target on it

[wintry quarry]

You'd have to iterate over all the triangles in each submesh until you find the triangle you hit

Probably best to build a Dictionary to map it beforehand

Otherwise it will be quite slow

[upper spire]

im so dumb

[upper spire]

yeah i have no idea what im doing i give up 💀 thanks anyway

[static cedar]

I'm not sure if u can do that without a custom inspector.
And on top of that, also serialise reference.

[static cedar]

Tbh, at that point, just make an attribute so it's reusable.

[sturdy lintel]

using System;
using UnityEngine;

public class TravellingBalls : MonoBehaviour
{
    private Vector3 startPoint;
    private Vector3 endPoint;
    private Vector3 direction;

    private GameObject travellingBallPrefab;

    private float speed = 6f;
    private float lifeSpan = 10f;
    private float spawnInterval = 1f;

    void Update()
    {
    }
}

I want to modify this script such that:

1. the travellingBalls will always stay on the lineSegmentLayer while translating between the startPoint & endPoint. Note that these 2 points can change their position, then the balls should change their path.
2. The balls will destroy themselves after the lifeSpan (in seconds) is over
3. The balls will keep on being generated after the spawnInterval (in seconds)

I want to achieve the following without the use of lerp, slerp, lookAt(), coroutines.
Can anyone please help me out ??

[rich adder]

spawnInterval should be handled by a ball spawner

same with spawning and timed lifespan

[static cedar]

Why lifespan too?

Actually nvm.

Unless he wants it to vary to each ballsssss.

[rich adder]

is easier to let the spawner destroy what it spawned

[sturdy lintel]

Could you guys help me code this part? I ain't able to

[static cedar]

First make a ball spawner class that inherits from monobehaviour.

[sturdy lintel]

Can we get on a call?

[teal viper]

You literally don't have anything. Did you even make an attempt?

Try to write some code and come back if it doesn't work.

Don't expect people to write the code for you.
Also provide more info on why you don't want to use lerp?

[static cedar]

I don't think he knows that ngl.

[sturdy lintel]

public class TravellingBalls : MonoBehaviour
{
    public GameObject travellingBallPrefab;
    private GameObject travellingBall;

    private Vector3 startPoint, endPoint, directionOfTravel;
    private float speed = 6f, lifeSpan = 10f, spawnInterval = 1f;

    void Update()
    {
        Debug.Log(startPoint + " " + endPoint);
        this.transform.position += directionOfTravel * speed * Time.deltaTime;
    }

    public void GenerateTravellingBalls(Vector3 _startPoint, Vector3 _endPoint)
    {
        startPoint = _startPoint;
        endPoint = _endPoint;
        directionOfTravel = (_endPoint - _startPoint).normalized;
        Debug.Log(_startPoint + " " + _endPoint);
    }
}``` 
This is what I tried to write so far. But the Debug.Log() inside update ends up printing Null

[static cedar]

But that has to be mentioned since that's what he's asking.

[teal viper]

Okay. That should've been the code to provide in the original message.

[teal viper]

I don't see why the debug log there should print null.
If it's an error, provide more details.

In fact it's impossible for it to print null there.

[sturdy lintel]

No error. I mentioned right it prints Null. I am calling this GenerateTravellingBalls() from another script. If I do Debug.Log() inside GenerateTravellingBalls() then it prints proper value

[teal viper]

Then it's not the debug log in this script that prints null..?

[slender nymph]

yeah it is 100% impossible for either of the logs in that code to print null since those Vector3s cannot be null

[teal viper]

Make sure your debug logs are informative and tell you what objects are involved. You can also look at the stack trace to see where it was printed.

[sturdy lintel]

The first Debug.Log is done from Inside the GenerateTravellingBalls() the 2nd Debug.Log is done from Update()

[cosmic dagger]

How are the logs printing null? The value within the logs are value types which cannot be null . . .

[sturdy lintel]

sorry 0,0,0 not null

[rich adder]

nothing here says null

[cosmic dagger]

You have to present your information correctly. . .

[sturdy lintel]

my bad

[slender nymph]

i'd bet you're calling GenerateTravellingBalls on a prefab and not the instance in the scene

[sturdy lintel]

This is what I am doing in another script

[slender nymph]

where do you assign tBall

[sturdy lintel]

I am dragging the TravellingBallPrefab in the editor inside the tBall

[slender nymph]

well there you have it.

[cosmic dagger]

You don't assign the instantiated object . . .

[slender nymph]

you probably want to call GenerateTravellingBalls on the object you instantiate on the previous line rather than on the prefab. Instantiate returns a reference to the instantiated object so you can assign that to a variable

[sturdy lintel]

I'm sorry, I didn't understand 😢 I am very new, just started learning 8days back

Could you explain in some other way

[slender nymph]

you're calling the method on your prefab rather than on the one that you just put into the scene

do you know what it means when a method returns something?

[sturdy lintel]

yeah

[slender nymph]

great! So Instantiate returns the object that was spawned. do you know how to get that returned object?

[sturdy lintel]

GameObject TBall = Instantiate(travellingBallPrefab, 
sphere1.transform.localPosition, Quaternion.identity);```

[slender nymph]

sure. but you probably want to make your travellingBallPrefab a TravellingBalls type rather than a GameObject type and it will return a TravellingBalls object. then you won't need to call GetComponent on it

[sturdy lintel]

I feel awful to ask you again. But I don't understand how to fix this yet 😢

[slender nymph]

show what you've tried and let me know what part you are not understanding

[sturdy lintel]

I haven't made any changes to the code yet. For now the smallest thing I want to achieve is. I want to move these travellingBalls between 2 points, after small interval the balls should respawn & travel between those 2 points

[slender nymph]

focus on the issue at hand first. you need to make sure that you are calling that GenerateTravellingBalls method on the object you instantiated and not on the prefab

[sturdy lintel]

If I use this, I can't do TBall.GenerateTravellingBalls() it throws error

[slender nymph]

#💻┃code-beginner message

[sturdy lintel]

I didn't understand what you meant by this.

[slender nymph]

the type of object you put as the first parameter for Instantiate is the type of object Instantiate returns. obviously GameObject does not have a method called GenerateTravellingBalls. that is on your TravellingBalls type. if your prefab variable is a GameObject type then Instantiate will return a GameObject. and how do you get your component from a GameObject?

[sturdy lintel]

right

using GetComponent<>

[slender nymph]

yes. except you can completely skip the GetComponent step if you just make your prefab variable the type you want to access

for example, if you were to pass your tBall variable instead of travellingBallPrefab it would return a TravellingBalls type because that's what tBall is. it's also conveniently your prefab too

[sturdy lintel]

TravellingBalls TBall = Instantiate(travellingBallPrefab, sphere1.transform.localPosition, Quaternion.identity);
TBall.GenerateTravellingBalls(sphere1.transform.localPosition, sphere2.transform.localPosition);

[slender nymph]

yep, there you go

just make sure you've actually changed the type for your travellingBallPrefab variable and that you drag the object into the inspector again. do that even if it shows it is still assigned

[sturdy lintel]

This is throwing an error "InvalidCastException: Specified cast is not valid.
(wrapper castclass) System.Object.__castclass_with_cache(object,intptr,intptr)
UnityEngine.Object.Instantiate[T] (T original, UnityEngine.Vector3 position, UnityEngine.Quaternion rotation) (at /"

[slender nymph]

yep and i just told you how to fix that

[sturdy lintel]

So this works now

So at first my prefab was being assigned to a GameObject type. But then what exactly was the issue with that? Why didn't the movement part of the script work exactly

This is the first time, I encountered this problem so trying to make a note of it. Could you point me to some resource so that I can read it as well

[slender nymph]

it had nothing to do with it being a GameObject type. as i already explained, you were calling the GenerateTravellingBalls method on the prefab not on the instance you spawned in the scene

[sturdy lintel]

So I created a prefab but then my other script was not able to understand the start,end points that I was assigning were for that created instance?

am I correct

[slender nymph]

not really

let's put it this way:
create a new txt file somewhere on your computer. add some text to it then save it. this file will represent your prefab.
if you were to copy that file to another place on your computer they would be two separate files so modifying one will not modify the other.
now open the original file again, add some text to it, but do not save. this operation represents you calling the GenerateTravellingBalls method on the prefab. since that method modified non-serialized variables they weren't changed (not that you'd want them to change in this case).
now look at the first copy you made. notice how it didn't change when you performed the previous operation (and how the prefab wouldn't have changed either)? yeah, that's what you were doing basically

and even if calling that method had changed the prefab, it would not have done anything to the object you had spawned on the line before, it only would have effected future objects spawned as clones of that prefab

[sturdy lintel]

Damn now I get it

Thanks for being so patient with me

I really appreciate it. From next time, I will make sure to convey my issues properly at beginning which I didn't do it right now. Sorry for the inconveniences

[pastel marten]

Can anyone give me some guidance here?

I want the player to walk in different directions based on the direction they are aiming and their movement direction. (strafe left, backward left, forward right, etc)
I tried playing with the code but I can't seem to figure it out.

Need to calculate the player rotation and movement direction difference, then activate animations based on that.
Already have the animations and animator controller set up, just not sure how to code this...

How should I code the animations to trigger based on the players rotation +/- movement direction?

Tried calculating the player.forward - movementVector, but it always returns 0f or it will return different angles based on which direction the camera is facing, which makes it impossible to trigger animations based on the angle. Is there a way to calculate the cameraForward rotation into the playerRotation and playerMovementDirection?

I made a short video clip displaying the problem. Any Help is Appreciated!

[eternal needle]

https://docs.unity3d.com/ScriptReference/Vector3.Angle.html
Is this what you need? Im not sure what you tried to calculate before but subtracting the 2 vectors shouldnt be 0 unless they were the same. Without seeing the code, its hard to suggest why they gave this result.

[candid oyster]

how can I make a gameobject's name a string?

[slender nymph]

wdym? because it already is a string

[candid oyster]

I mean

uhmm

I have a public GameObject

lets say its name is A2

[eternal needle]

You wanna assign it a certain value I assume?

[candid oyster]

and then I have a string variable

and I want the string variable

to be the gameobjects name + something

stringvariable = GameObject + "2"

[slender nymph]

did you know that you can finish typing your full thought before pressing enter?

[candid oyster]

true

[slender nymph]

also GameObject has a name property that will return its name, which you would know if you had consulted the !api

[candid oyster]

Thanks

so GameObject.name?

[slender nymph]

wait is that not the command. maybe !docs

[eternal falcon]

GameObject.name will return the name of the game object as it appears in the scene

GameObject.name also has a setter so you can change the name of the object on the fly with GameObject.name = "foo"

I was trying to put the code in the TopDownPlayerMovement script in the MovePlayerTowardTarget(Vector3 targetVector) method when RightClickHold

[eternal needle]

use the code command above to paste it to a code site. discord trims it

[pastel marten]

Here in this block section is where I was making previous attempts:

private void MovePlayerTowardTarget(Vector3 targetVector)
    {
        var speed = MovementSpeedWhileWalking * Time.deltaTime;
        //playerSpeed = MovementSpeedWhileWalking;
        if (_input.RightMouseHold)
        {
            isAiming = true;
            speed = speed * MovementSpeedWhileAiming;

        else if (!_input.Shift)
        {
            playerAnimator.SetBool("isRunning", false);
        }

        targetVector = Quaternion.Euler(0, _camera.transform.rotation.eulerAngles.y, 0) * targetVector;
        var targetPosition = transform.position + targetVector * speed;
        transform.position = targetPosition;
    }

let me try pastebin for the full script

[slender nymph]

skipped right over that "Large Code Blocks" section, eh?

c# is the language

[pastel marten]

I should have saved a copy of my edited script where I made an attempt to calculate the angle as a float based on playerRotation and movementDirection.

It worked... except for when I rotated the camera, then it was out of whack. It only worked for like World-Z direction

[eternal needle]

where are you doing the comparison for targetVector and transform.forward after you rotate it by Quaternion.Euler(0, _camera.transform.rotation.eulerAngles.y, 0)

[pastel marten]

I had it in the MovePlayerTowardTarget() method

after the if (_input.RightMouseHold) statement

or in*

Unless you are asking about the camera rotation? That's handled by a different script.

[eternal needle]

it would have to be later on in the function, after the vector is rotated. from what i see, doing it at that point would mean you are just checking the players input compared to the players transform.forward

like the players input could be (0, 0, 1) the entire time but rotating the camera and doing Quaternion.Euler(0, _camera.transform.rotation.eulerAngles.y, 0) * targetVector is what you gives you movement in the direction you want. So thats the movement you wanna compare to the forward, not (0, 0, 1)

[pastel marten]

so what I did that somewhat worked before was

angle = Quaternion.Angle(player.transform.rotation, Quaternion.LookRotation(moveDirection));
``` but maybe I needed to use a global rotation instead of the local? or visa versa? Because the angle (float) would differ based on the camera's rotation around the player.

are you suggesting I should try 
```csharp
angle = Quaternion.Euler(0, _camera.transform.rotation.eulerAngles.y, 0) * targetVector;
```?

I can give that a shot, but the players rotation and aiming rotation can sometimes differ from the camera's y-angle

I was under the assumption I should base the animation states according to the players rotation & movement direction.

[eternal needle]

im saying compare the vector given from Quaternion.Euler(0, _camera.transform.rotation.eulerAngles.y, 0) * targetVector and transform.forward of the player

with Vector3.Angle

[pastel marten]

var Vector3 modifiedDirection = Quaternion.Euler(0, _camera.transform.rotation.eulerAngles.y, 0) * targetVector;

float angle = Vector3.Angle(playerForward, modifiedDirection);

is that essentially what you are saying?

[eternal needle]

Unless im misunderstanding something, you want to know when theres a big difference between where the player is trying to move and where they are looking, like looking one way but moving the other way, so you can play animations based on that.

[pastel marten]

Yes, I want the animations to change based on the direction the player is facing when aiming and the direction the player is moving. 🙂

[eternal needle]

you already calculate the value in line 145 of the pastebin you posted, so you can just use that. but yea get the angle then just check if the angle is greater/less than some amount. Based on that amount, play a different animation (or change some value so whatever other code can play the correct animation)

[pastel marten]

Right, thanks.

So that is just returning 0f constantly.

I changed it to the following and it seems to be working, no matter what the camera's rotation is:

float angle = Quaternion.Angle(transform.rotation, Quaternion.LookRotation(targetVector));

The only issue I see is that StrafeLeft and StrafeRight are both returning 90° angles. I wonder how I would adjust it so that StrafeLeft is -90 and StrafeRight is +90? hmmm....

(Making progress!) I appreciate your help! Just have to figure out how to get a different value for Strafe Left/Right

[eternal needle]

you shouldnt need to use Quaternion.Angle here, especially because you're now constructing a quaternion from the targetVector. With vector3 you could use
https://docs.unity3d.com/ScriptReference/Vector3.SignedAngle.html

[lean basin]

Hello, I have a prefab, and I wanted to change one of it's component to a class that inherited it. How do I do that without changing the component's current property and references in the inspector?

[pastel marten]

Aw man (or lady), you are amazing! It works!! 🥳

Here is the final code I implemented at the end of the MovePlayerTowardTarget():

float signedAngle = Vector3.SignedAngle(transform.forward, targetVector, Vector3.up);
print("Signed Angled = " + signedAngle);

Anyways, Thank you very very much! *Big high five!

[pseudo sable]

I'm not sure you can do that, probably your best bet is to add the new component onto your prefab and copy the settings over while they're on screen, then remove the old one

if they have the same properties you might be able to right click old one > copy values, right click new one > paste values, maybe

[lean basin]

this one didn't work. And I haven't added any new properties. Just empty script that inherited that component.

[pseudo sable]

might just have to be a manual job then unfortunately, as far as I know the editor isn't really aware of any inheritance and will treat them as basically different components

[tender stag]

how can i make each required item i dont have template name text turn red? and if i do have it to turn white```cs
if(inputItem)
{
foreach(var template in templates)
{
foreach(var requirement in inputItem.GetProcess<RepairProcess>().repairRequirements)
{
int amount = InventoryManager.Instance.inventory.GetAmount(requirement.item, InventoryManager.Instance.inventory.inventoryCells);

        if(amount >= requirement.amount)
        {
            template.transform.GetChild(1).GetComponent<TMP_Text>().color = Color.white; // Set text color to white
        }
        else
        {
            template.transform.GetChild(1).GetComponent<TMP_Text>().color = Color.red; // Set text color to white
        }
    }
}

}```

also i dont really want to use transform get child

but i dont see another way of doing it

[quaint thicket]

I'm trying to make a gameobject rotate the same direction as a camera but only using the Y rotation. For instance, even though the camera can look in all directions the gameobject would only rotate left/right and not up/down.

Never mind, I solved it. Talking about it really does help.

[pseudo sable]

you could add a component script onto the template gameobjects that handles it for you, so you would only have to call template.SetTextColor(color) (for example) - that way you can just change the implementation in the template code if you find a better way to do it

also might be worth looking into .GetComponentInChildren<T>()

This method checks the GameObject on which it is called first, then recurses downwards through all child GameObjects using a depth-first search, until it finds a matching Component of the type T specified.

[tender stag]

that'll be the best otion

thanks

[pseudo sable]

no worries!

[quaint thicket]

I'm using a Cinemachine freelook camera and want to allow it to look upwards. For instance, when I use the mouse to rotate the camera below a gameobject it will show the camera facing upwards.

Solved it. The Cinemachine's FreeLook camera's Orbits > BottomRig needed to be set to a minus number like -4.5.

Still having a issue with the camera kind of zooming in to the middle rig while transitioning from looking upwards/downwards

[eternal needle]

This isnt really a code question. Theres a #🎥┃cinemachine channel. Just to quickly suggest something, you probably have a small radius for your middle rig if it seems like its zooming in.

[quaint thicket]

I thought the same thing an tried changing it but didn't help. But thank you for pointing out I was asking this in the wrong channel.

you need to import the namespace system at the top

[lean basin]

I have this script:

public enum State {None, Idle, Walk, Rotate, Check, Chase,ChaseDynamic, Peek,InitialPooled, Pooled, Despawning, DebugFreeze, Examine, Pounce, Laugh}
public void ChangeState(State newState)
{
    nextState = newState;
}

But why doesn't it appear as an option in UnityEvent trigger dropdown?

[pseudo sable]

for a button event or?

[lean basin]

this event

custom UnityEvent. Im guessing it would be the same for button's OnClick event, but haven't tried,

[slender cargo]

So I am working on a silly game of mine, How would I get a line renderer with physics between 2 objects?

Line renderers have no physics, so does anyone have any suggestions?

Rope physics?

[pseudo sable]

it could be that the handler needs to have some kind of BaseEventData as a parameter before it gets picked up in the UI, possibly, try adding BaseEventData event as the first parameter of your method and see if it at least sees it

(or even just as the only parameter, just to test)

[slender cargo]

In theory I could attatch a few rigidbodys with hinge joints, but idk whether it would look right...

[lean basin]

BaseEventData don't appear when I used it as the only parameter. However string appear.
Hmmm, did perhaps UnityEvent hates enums? I wanted to pass an enum
it would be funny if I had to create a class for this

[pseudo sable]

quick check, looks like enums are indeed not supported!

you could cast back and forth from a string or int that represents the enum though

[pseudo sable]

thinking out loud, you could create the rope with rigidbodies, but have them invisible and use a linerenderer to draw a line through them, so the line is just reacting to whatever the rigidbodies are doing?

[pseudo sable]

another solution would be having a different handler for each enum type, which may or may not be appropriate based on your project, like this:

public void FuncWithEnum(EnumType enumType) {
    switch (enumType) {
        case EnumType.Value1:
            //Do something
            break;
        case EnumType.Value2:
            //Do something
            break;
    }
}

public void FuncWithEnumValue1() => FuncWithEnum(EnumType.Value1);
public void FuncWithEnumValue2() => FuncWithEnum(EnumType.Value2);

then your event can just point to FuncWithEnumValue1(), etc. might get a bit wild if you're doing anything a bit more complex though

[slender cargo]

That’s a great idea!!

[lean basin]

so making new argumentless function to call the enum function. it should work for now. Thanks for your assistance

[lean basin]

Where did you obtain this information?

[pseudo sable]

no problem!

[pseudo sable]

let us know how you get on!

[slender cargo]

On lunch break but will do in a bit!

[pseudo sable]

https://discussions.unity.com/t/enum-as-a-function-param-in-a-button-onclick/214010/7
it's talking about the OnClick delegate but i'm sure it'll all come from the same base

(thread is quite old so maybe it's supported now but i suspect since it isn't working for you, it's still not supported - unless there's a new fangled approach)

[azure zenith]

I am supposed to make a throwable item explode if it touches the ground in an OnDestroy() method, how would I do this?

[pseudo sable]

detect collision between the item and the ground, call Destroy(gameObject), then in the OnDestroy() you can spawn a new gameobject that is the explosion

OnDestroy() gets called on a gameobject just before it is removed

[azure zenith]

Oh

That makes more sense

Thank you 🙂

[pseudo sable]

no worries!

[azure zenith]

If you are still here, I tried it and it worked. However, if I press restart the game, every single throwable explodes

I guess that is normal...?

[cosmic dagger]

when you load a scene, everything from the current scene is destroyed, therefore, OnDestroy is called on all of the GameObjects . . .

[azure zenith]

I only want it called on the throwable that the player throws

Or maybe that is not possible

[cosmic dagger]

OnDestroy is a unity event function that is automatically called when a GameObject is destroyed . . .

[teal viper]

You can't control the OnDestroy function being called, but you can control what happens inside of it.

[cosmic dagger]

you don't even need to use it. just destroy the GameObject when it collides with an object (or only the ground) . . .

[azure zenith]

From the Unity's website: Note: OnDestroy will only be called on game objects that have previously been active.

[pastel marten]

Would anyone be able to help me figure this out?

I am trying to set the Movement Angles X & Y for a Blend Tree and can't quite figure out the proper method of doing so.

Here is the method I am attempting:

private void ApplyAnimation()
    {
        // Calculate normalized movementAngleX and movementAngleY.
        movementAngleX = Vector3.SignedAngle(transform.right, targetVectorA, Vector3.up);
        movementAngleY = Vector3.SignedAngle(transform.forward, targetVectorA, Vector3.up);

        // Ensure that the resulting values are clamped to the range [-1, 1].
        movementAngleX = Mathf.Clamp(movementAngleX, -1f, 1f);
        movementAngleY = Mathf.Clamp(movementAngleY, -1f, 1f);

        // Set the Blend Tree parameters in the Animator
        playerAnimator.SetFloat("MovementAngleX", movementAngleX);
        playerAnimator.SetFloat("MovementAngleY", movementAngleY);

        print("X = " + movementAngleX);
        print("Y = " + movementAngleY);
    }
``` it gets the targetVectorA from here:
```csharp
        targetVector = Quaternion.Euler(0, _camera.transform.rotation.eulerAngles.y, 0) * targetVector;
        var targetPosition = transform.position + targetVector * speed;
        transform.position = targetPosition;

        targetVectorA = targetVector;

The -1,1 values seem correct in the debug console ~ the problem is I want it to use all the in between values and also set back to 0,0 when there's no input or movement.
Also, if I walk straight forward movementAngleY = 1 and movementAngleX does not go back to 0. Seems like a constant 1,1 or -1,1 and never a 1,0 or 0,-1

Should I be using Mathf.Lerp for this? Or is there another math function I should be using?

Here is the full script: https://pastebin.com/SHqHF6xD
And here is an image of my Blend Tree below:

[swift crag]

I don't understand your logic. You're using Vector3.SignedAngle, which will produce values between -180 and 180

It's going to tell you the angle between two vectors

But that's not what you want. You want to compute X and Y values telling you how much you're moving in those directions

[pastel marten]

Yea, my first goal was to get the difference between the player look rotation & player movement direction/targetVector so I could activate animations based on the angle. (Strafing Left/Right, Walk Backward Left, etc)

[swift crag]

You should use Vector3.Dot. If you do this:

Vector3.Dot(transform.right, movementVector);

you'll get a value between -x and x, where x is the length of movementVector

If the two vectors are aligned, you'll get x

if they're pointing in opposite directions, you'll get -x

Alternatively, convert the movement vector into local space and then just use its X and Z components

var local = transform.InverseTransformVector(movementVector);

local.x will be the left-right component and local.z will be the forward-backward component

the Inverse methods take a world-space vector and convert it to local-space

[pastel marten]

Let me give this a try. Thanks for helping! I will let you know if it works. 👍

[dusk dust]

I searched about the Resource folder, and they said it's not recommended in production, why is that and what is the alternative?

[swift crag]

I would not say it's "not recommended in production"

[heady nimbus]

Did debugging in vscode get fixed with the new c# dev kit stuff?

[swift crag]

yeah, worked well when I used it a week ago

[swift crag]

It is a lot less flexible than Addressables, for sure

but sometimes you just need to load an object by a name with no other references

for example, I recently added a "singleton scriptable object" type to my project

it's a singleton that initializes itself like this

[heady nimbus]

Thanks I'll look into it then. Didn't want to waste my time if it was still busted. I'm getting failed to attach errors, but I'm sure I can find the solution somewhere

[swift crag]

_instance = Resources.Load<T>(typeof(T).Name);

i should really make a subdirectory to put these singleton assets in

[azure zenith]

From the Unity's website: Note: OnDestroy will only be called on game objects that have previously been active.
Is it possible to disable it on objects that have been active?

[dusk dust]

Ok thx 💙

[stable jackal]

helo im pretty new and im following a guide for a game, im using Unity 2018.3.7f1 and i need to import Navmesh components, im on the github link right now but i dont know how to "import" this navmesh into my game/unity project

[swift crag]

can you link me to the guide?

[stable jackal]

sure do i send it here or to your dms

[swift crag]

here.

[stable jackal]

https://youtu.be/UjkSFoLxesw

dude just said go to this github link and import navmesh components, and idk how to do that

[swift crag]

see the readme on the github page

Clone or download this repository and open the project in Unity. Alternatively, you can copy the contents of Assets/NavMeshComponents to an existing project.

So, you can just copy that entire NavMeshComponents folder into your project

[stable jackal]

ohh

[swift crag]

Make sure to click the correct link here first

master for 2020.3-LTS, 2019.3 for up to 2019.4-LTS, 2018.3 for up to 2018.4-LTS and 2019.2, 2018.2, 2018.1, 2017.2 for up to 2017.4-LTS, 2017.1, 5.6.

(these are hyperlinks on the readme)

[stable jackal]

thank you

[swift crag]

oh, that link is busted

it's not set up correctly

You can switch branches in this dropdown menu

You will want to pick 2018.3

then download the zip, unpack it, and copy NavMeshComponents into your assets folder

[stable jackal]

so im just gonna download the assets folder then shove it into my project?

[swift crag]

pretty much

[stable jackal]

alr thanks thanks

[swift crag]

the important folder in there is NavMeshComponents. The others are samples and stuff

[stable jackal]

im at the 2018.3 branch i dont see a green download button how do i download this (sorry i am very new to all this)

nevermind, found it

[subtle veldt]

Hello !
This is the code I use to make my player move :

    void Update()
    {
        playerRigidbody.velocity = new Vector2(inputX * walkingSpeed, playerRigidbody.velocity.y);
    }

    public void Move(InputAction.CallbackContext context)
    {
        inputX = context.ReadValue<Vector2>().x;
    }

But I need to change it because it causes weird things to happen when I link my player to another object with a SpringJoint2D. How would you make your player move in a 2D game which uses Physics ? (i'm using grappling hooks for example)

[stable jackal]

question how do i add like my gameobject ground/player into a layermask

[pastel marten]

@swift crag

It's working as intended! Thank you!

        movementAngleX = Vector3.Dot(transform.right, targetVectorA);
        movementAngleY = Vector3.Dot(transform.forward, targetVectorA);
        float length = targetVectorA.magnitude;
        movementAngleX /= length;
        movementAngleY /= length;
        movementAngleX = Mathf.Clamp(movementAngleX, -1f, 1f);
        movementAngleY = Mathf.Clamp(movementAngleY, -1f, 1f);

        playerAnimator.SetFloat("MovementAngleX", movementAngleX);
        playerAnimator.SetFloat("MovementAngleY", movementAngleY);

[gray python]

Hello, i'm wondering if anyone could help me understand the built in physics engine a lil bit, right now this dash function is working fine while on the ground and while moving, however it's not applying the force correctly/at all while in the air during a jump. Could anyone tell me why, or maybe what to watch out for?

void Dashing() {
    float dashForce = 30f;
    if (Input.GetButton("Dash")) {
        if (IsFacingRight() == true && !hasDashed) {
            Debug.Log("Dash Right");
            rb.AddForce(Vector2.right * dashForce, ForceMode2D.Impulse);
        } else if (IsFacingRight() == false && !hasDashed) {
            Debug.Log("Dash Left");
            rb.AddForce(Vector2.left * dashForce, ForceMode2D.Impulse);
        }
        hasDashed = true;
    }
}

[silk night]

How does it behave while in the air?

[polar acorn]

Are you setting the velocity directly at any point? You're probably overwriting the dash velocity

[gray python]

doesn't apply any force at all, the jump itself is normal, it doesn't interfere with the jump's velocity

[gray python]

I'll look into that, maybe my base movement forces are affecting it, will get back to you on that one in a sec

Can someone help me please ?

[azure zenith]

If I add a tag to an empty object, will it also apply to all its children?

[silk night]

Why dont you try it

[azure zenith]

I did and I do not think it does

[heady nimbus]

[swift crag]

Tags and layers both apply just to the object you set them on

but Unity does offer to apply a layer to all children if you want

[azure zenith]

Basically, I made an empty object to store all my cubes

Does that mean the empty object is a parent and all its cubes are child objects?

[swift crag]

That sounds reasonable.

The Hierarchy shows you all of the objects in the scene. In this example, "Camera Controls" is the parent of "Main Camera", and "Main Camera" is the child of "Camera Controls"

Every item in the Hierarchy is a GameObject. Every GameObject has a Transform.

and the Transform is what has a parent / has many children

that's why you do transform.SetParent(otherObject.transform), not SetParent(otherObject)

[azure zenith]

So if I add a tag to the parent object, it will apply the same tag to all its children objects?

[swift crag]

No.

[azure zenith]

Yes

Oh

[swift crag]

Each game object can have a tag

[azure zenith]

I see

[swift crag]

Tags aren't propagated to children or anything like that

[azure zenith]

What if I added a script?

[swift crag]

Sure, you could set the tags of all of the children if you wanted to

[somber wren]

someone has any idea of it is not hitting ?

also my ray are clearly hitting ? the layer is all on default

[polar acorn]

The fact that it's curved leads me to believe this is not the ray you've drawn

It's just another red gizmo

[somber wren]

its a serie of rays

its a coded Arc RayCast fonction, its just a serie of rays that end up doing an ArcRay

kind of like that

[shell sorrel]

does the raycast originate from inside the wall

if so it would not hit the collider

[polar acorn]

And is it always supposed to be a 180 degree arc? If so, it seems like it's working just fine

[somber wren]

not it orginates from above the spider, i mean the first ray

[polar acorn]

Pictured is only about a 90 degree arc, and the last segment is the one that hits the wall

[somber wren]

yes, but its not returning that it hits as it should

no, its supposed to stop when it hit something

[shell sorrel]

test assumptions

do 1 raycast with the same settings you know will hit and see what happens

[polar acorn]

Make sure the thing you're expecting to hit is in the layer mask

Use that same mask with something easy like an infinite forward ray

[somber wren]

ill see

[shell sorrel]

if something does not work, i tend to just strip it back to the most simple test case that uses the same parameters

[somber wren]

a simple infinite ray doesnt work too :(

[azure zenith]

I have a lot of game objects and adding a script manually to all of them would be an effort?

[shell sorrel]

why would you need to do it manually to all of them though

[pseudo sable]

@azure zenith have a look here
https://discussions.unity.com/t/is-there-an-easy-way-to-apply-the-same-tag-to-all-children-of-an-object/28582/2

few solutions depending on how you want it to work

[swift crag]

what are you trying to accomplish here?

not "setting tags on objects"

what are you trying to make your game do?

[heady nimbus]

Dumb question, if I want an enemy to be able to pass through the player, but still collide with ground and walls and use physics, what options do I have to handle this

[shell sorrel]

@heady nimbus physics layers

https://docs.unity3d.com/Manual/LayerBasedCollision.html you can define what layers interact with what other layers in this matrix

[heady nimbus]

Awesome, thank you, I'/ll look into it

[polar acorn]

Then it would seem your targets are not in that layer mask

[heady nimbus]

Hmm, I don't think this is what I want. Not sure I can accomplish what I'm trying to do without multiple colliders actually...

I want the enemy to still trigger collision with the player, but pass through it. I probably can't do this with a rigid body though

[shell sorrel]

would need mulitple colliders then

1 that does the real collisions but ignores the player

then a other that is just a trigger collider on a layer that colliders with player

[heady nimbus]

Ok, so I could one that uses the Layer Overrides -> Exclude Layers -> Player

Cool, I think it's working, thanks

Yes the answer to that question is whether I am being asked to trust severely undercaffeinated me or dangerously overcaffeinated me (I have no other forms)

[swift crag]

you don't need Visual Studio installed to use Unity or another core editor..

oops, was scrolled back

[swift crag]

people realized that you could put malicious code into things like Tasks

[heady nimbus]

Kind of sad to see it go, but yes, setting velocity to 0 before locking movement and processing knock back DOES prevent the rocket launch effect I was getting. Lol

[swift crag]

so the default is to run in an "untrusted mode" that disables that stuff

[azure zenith]

I believe OnCollisionEnter checks all objects colliding with an object?

Unless you tell it not to?

[heady nimbus]

If the objects have a collider, yes

[azure zenith]

Then a specific object will collide with the object?

[swift crag]

.

what are you trying to do?

don't ask about your attempted solution. ask about your original problem.

hello, the ammo number does not update to 20 when I pick up the ammo clip, and the sound plays when I eneter the 3rd level right away, and play on awake is off on the audio source

[polar acorn]

Log the object this collides with. If you get a log right away, then this object is colliding with something playing the sound. If you get no log, the sound is playing somewhere else

Okay, when a player throws a grenade into a cube, it will explode and the cube will destroy, but if they also go through the cube, it will also explode and destroy.

[heady nimbus]

Sounds like you just need to check what is colliding with the cube before destroying it

if (col.gameObject.GetComponent<Grenade>())

Or something along those lines

[azure zenith]

Cheers

So yeah, basically I do not want the cube to explode and destroy when a player goes through it

[mellow jacinth]

Bruh

[polar acorn]

Bruh what I answered your question

[swift crag]

Indeed.

I prefer using TryGetComponent. It can be very handy for doing an early-return

[heady nimbus]

Yea, try is probably better, but I suck as this and always forget it. Haha

[swift crag]

void OnCollisionEnter(Collision collision) {
  if (!collision.gameObject.TryGetComponent(out Grenade grenade))
    return;

  // do stuff with the grenade variable
}

TryGetComponent returns false if it fails

if it succeeds, then you'll have a variable named grenade holding the Grenade

[silk night]

What the hell is going on with my nav-agents here?

https://img.sidia.net/ZEyI5/BOmAJuDe53.mp4/raw

I basically tell them to follow my player:

public void OnPosition(GameEntity entity, Vector3 value)
{
    Agent.SetDestination(value);
}

The onposition is called whenever my player moves to a new position

[unique hull]

I am not an expert at the navmeshes , but i am using destination on all my units without any problems. Try using that instead of SetDestination

[silk night]

    /// <summary>
    ///   <para>Sets or updates the destination thus triggering the calculation for a new path.</para>
    /// </summary>
    /// <param name="target">The target point to navigate to.</param>
    /// <returns>
    ///   <para>True if the destination was requested successfully, otherwise false.</para>
    /// </returns>
    public bool SetDestination(Vector3 target) => this.SetDestination_Injected(ref target);

    /// <summary>
    ///   <para>Gets or attempts to set the destination of the agent in world-space units.</para>
    /// </summary>
    public Vector3 destination
    {
      get
      {
        Vector3 ret;
        this.get_destination_Injected(out ret);
        return ret;
      }
      set => this.set_destination_Injected(ref value);
    }

They are doing the same thing

[timber tide]

lol at the spinning cube

do you get the same results without rigidbody

ideally you don't want to use rigidbody anyway

[silk night]

OHHH that might be it xD

[timber tide]

Rather, rigidbody is fine, but using it for collision detection like this does cause complications.

ideally, you'd make your own character controller and handle how things should be pushed back instead of relying on the physics system.

[silk night]

removing / setting the rigidbody to kinematic fixes the issue

I dont want player/monster collision anyways

Aslong as the monsters dont clump up while following me its fine, and navagents seem to prevent that by default

https://img.sidia.net/ZEyI5/DoDApoXO27.mp4/raw

[timber tide]

if you do want to use kinematic, you can potentially try just adding *your own displacement methods around your character passively to push stuff back

[silk night]

Nah basically I just need an ontriggerenter to damage my player when its touched

[buoyant knot]

is there any overhead for using tuples?

[swift crag]

tuples are reference types, so they're different from a struct

i guess this could result in more garbage being produced than if you were passing structs around

[buoyant knot]

I’m making a system where I need to store pairs of colliders (where col 1 ignores force from col2), and I’m contemplating Dictionary<Collider2D, HashSet<Collider2D>> vs HashSet<Tuple<Collider2D, Collider2D>>

[short hazel]

First one if you need to access the second element of the pair using the first, and fast

[buoyant knot]

also wtf tuples are reference types?

[short hazel]

Else second one

[buoyant knot]

I just need to check the pair really fast

[brave compass]

The old System.Tuple is a class. But the language feature (x, y) has been replaced with System.ValueTuple, which is a struct.

[short hazel]

In recent enough versions of C#, there's ValueTuple, a struct

[buoyant knot]

ie if I have colliders 1 and 2, do we ignore

[elfin eagle]

im new to scriptable objects, so like can you not assign gameobjects or anything else?

[buoyant knot]

hmmm, maybe ValueTuple will do this faster?

[short hazel]

Second one then, tuples will correctly produce hash codes for the pair

It defaults to ValueTuple now

[buoyant knot]

ScriptableObjects don’t usually live in the scene, if that is what you mean

[elfin eagle]

ohh ok is it like in project files only?

[buoyant knot]

SOs are usually used as immutable data that you store separately that can be used to populate/query other things

[cosmic dagger]

you can't assign a scene GameObject . . .

[brave compass]

You can't assign anything that lives in a specific scene. The ScriptableObject could be loaded at any time, when any scene is loaded, so the object might not exist.

[buoyant knot]

so if I am making a Goomba SO, I could add in: Goomba Prefab (to make it), string for enemy name, bool for if I can stomp it…

but 1) you really do NOT want to write to SOs during runtime. You can, but I always pay the price

like, you do NOT want enemy boss current HP in an SO

you DO want enemy boss Max HP in an SO. That does make sense

understand?

[buoyant knot]

back to this, it would be an Enemy SO, which you can make a new file tied to Enemy SO, which corresponds to GoombaData

[elfin eagle]

alright okay i see

[buoyant knot]

So I define EnemySO with: GameObject prefab for enemy, string for name, bool for stompable…
Then [CreateAssetMenu()], and you can make a new EnemySO file

then you fill that new EnemySO file in inspector with goomba data, and call it GoombaEnemyData

then again right click on asset menu to make another EnemySO, and we fill it out again, but this time for Koopas

right click asset menu => new EnemySO file => make Piranha plant file

[timber tide]

yes

[buoyant knot]

then in game, I would make an EnemyDataHolder Monobehaviour, for example. This is a component that goes in the prefab, and I have a Serialized Field for EnemySO, and connect it.

[elfin eagle]

I have this main problem so I have a game object in scene one, and in scene two there is a prefab of that game object. My character has a script attached to it that the game object in scene 2 needs to access but it cant since it is from originally from scene 1 (Im using do not destroy on load). I need help to find a way that the gameobject in scene 2 can access it when the player enters the scene

so how could I use the scriptible object to fix this? or is there a different way

[buoyant knot]

So every goomba, koopa, and piranha plant has its own EnemyDataHolder component for every new one, and that component has a reference to the data for that specific enemy

[timber tide]

ye

[buoyant knot]

yeah

[timber tide]

I like to add constructors on my SOs too so I can just call them to construct them right from it. Assuming it will only ever be inserted by one type of monobehaviour.

[buoyant knot]

scriptable objects do not exist in any scene

I try not to ever construct SOs outside asset menu. GC doesn’t automatically clean up / destroy them when done

which is obnoxious

[timber tide]

Oh, no I mean I construct the enemy by calling the SO, instead of the enemy prefab script

[buoyant knot]

scenes are basically giant prefabs. The scene has a bunch if gameobjects, and each gameobject has components. Those components can reference SOs or prefabs. And prefabs can have gameobjects with components that reference SOs

[timber tide]

just a different way to implement it

[buoyant knot]

oh yes. always

I always instantiate prefabs by looking into an SO

example: GetTile from tilemap => tilebase for a given tile => big dictionary gives me the SO associated with that tilebase => that SO has a field for a prefab

this way the tile on the tilemap is tied to a prefab

does all of this make sense?

[swift crag]

this is very important if you're throwing them in a HashSet

otherwise two tuples with the same elements will still have different hash codes

[buoyant knot]

and ty guys.

[brave compass]

Does the order not matter for the hashcode ValueTuple generates?

Pretty sure it does. (colliderA, colliderB) != (colliderB, colliderA)

[sage mirage]

Hey, guys! I have a question. Can I use a lot of Audio Sources on a specific game object? If yes how to manage on this object the sounds?

[swift crag]

You can have multiple audio sources. You'll just need to put in a little more effort to pick the right one

[cosmic dagger]

i do believe the order is necessary to produce the correct hash . . .

[swift crag]

Dragging a game object into a field will pick the first matching component on it

But you can drag a specific component into a field instead.

[sage mirage]

For example, I want to add for the player game over sound when he collides with an object and also hit sound when the collision occurs

[buoyant knot]

yes. SerializeField to get references to specific ones

[swift crag]

If you're playing lots of one shot sounds, you should just have a single audio source that you pass various AudioClips to

Multiple audio sources are only needed if you want to have several simultaneous non-one-shot sounds, or want to have different audio settings for different sounds

[brave compass]

Yeah, this appears to be the method it uses to generate the hash of a two element ValueTuple.

public static int Combine(int h1, int h2) => (h1 << 5 | h1 >>> 27) + h1 ^ h2;

[buoyant knot]

that is probably cleaner tbh

[sage mirage]

Can I pass to a single Audio Source a lot of clips? There is only one space for audio clip?

[swift crag]

You'd use AudioSource.PlayOneShot

audioSource.PlayOneShot(someClip);

This does not use the audio clip field on the audio source

[buoyant knot]

so let’s say you are looking at a gameobject with like 20 different audio sources, but it also has all the colliders etc. That will be a mess

[swift crag]

I prefer to put different audio sources on different game objects

I can add audio filters to each one independently, and it's just easier to wrangle them

[sage mirage]

Yes but if i have the clip inside of my audio clip on audio source then I can play only this sound if I am not wrong?

[swift crag]

No. You can pass whatever you want to PlayOneShot.

That audio clip field is only used when you Play() the audio source.

[buoyant knot]

you probably want to make an SO with separate fields for: death SFX, dmg SFX, running SFX, idle SFX etc. if it gets complicated

[swift crag]

PlayOneShot does not set the field and doesn't care about the field. You can have many one-shot sounds going simultaneously

[buoyant knot]

if you don’t need to make multiple gameobjects with similar SFX needs, you can use field: SerializeField to specify specific audio clips

[sage mirage]

So, the field is important when I have to manage for example background music? For example, back music for my main menu and back music for main game?

[swift crag]

It's used when you Play()/Pause()/Stop() the audio source

Which you usually do for things like music

[buoyant knot]

which you don’t usually want two of at the same time

[sage mirage]

@swift crag To tell you the truth, I didn't know that with a single Audio Source you can handle with PlayOneShot() every sound you want. Thanks! I will see what I can do with all your suggestions.

[spice smelt]

i need help

[buoyant knot]

PlayOneShot is a method for an AudioSource that takes an AudioClip as an argument

[short hazel]

PlayOneShot also has the ability to stack the sounds. Like call it 3 times with 3 different clips, and it'll play them all blended in. Up to a certain limit of course

[buoyant knot]

myAudioSource.PlayOneShot(myAudioClip)

myAudioSource can come from GetComponent. myAudioClip comes from SerializeField OR from a scriptable object

[rich adder]

https://dontasktoask.com

[buoyant knot]

I’m going to take the plunge btw, fen. I’m going to refactor all my physics to manually do the simulation with kinematic RBs. It’s going to take a while, but I think will be worth it.

[spice smelt]

what if i want all of my weapons to react when jumping for examle little move

and also how do i add a soudeffects

[buoyant knot]

AudioSource component

[golden ermine]

Can someone help me do this? I have an script that is attached to player canvas and it counts have many wood logs is collected and it shows in in the textUI. I have prefab that is Campfire with sprite set to not on fire and when player collects 3 wood and enters campfire trigger it will change sprite to campfire that works with animations and it will heal player when its inside of its trigger. I have trouble with this cause Campfire is prefab and im counting the wood in player canvas so i cannot assign it from script inside campfire prefab. Can someone help with that

[spice smelt]

when I jump i dont want them to be steady in one place i just want them to follow my camera with little delay

[wintry quarry]

you're all over the place. Solve one problem at a time.

[spice smelt]

okay the weapons thing first

how do I make them follow my camera with a little delay

[wintry quarry]

follow the camera?

is this an FPS game?

[spice smelt]

YE

[wintry quarry]

Google "unity fps weapon sway" and find a tutorial

[short hazel]

Weapon sway is the term

[golden ermine]

PlayerUI script: https://hastebin.com/share/uwucamigiq.csharp

[buoyant knot]

you can not store persistent info in a prefab

prefab campfire script needs to be able to get a reference to the count

[golden ermine]

this script is not in prefab, its in canvas that is inside game scene

[sage mirage]

@swift crag Hey! Something else about before. Do I have to add my Sound Effect from Project windows right to my Hierarchy in order to use PlayOneShot from the single Audio Source that I have?

[golden ermine]

and also i want multiple campfires

[swift crag]

AudioClip is not a component. It is an asset.

[buoyant knot]

you might want a singleton that gives access to the total game inventory/score

[swift crag]

You should add fields to your player component to hold the audio clips

like [SerializeField] AudioClip hurtSound;

[violet topaz]

does anyone know how to assign the player to the camera follow script when changing scene ```cs
public class CameraFollow : MonoBehaviour
{
[SerializeField] private Vector3 offset;
[SerializeField] private float damping;

public Transform target;

private Vector3 vel = Vector3.zero;


private void FixedUpdate()
{
    Vector3 targetPosition = target.position + offset;
    targetPosition.z = transform.position.z;

    transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref vel, damping);
}

}```

[buoyant knot]

CampfireScript can use Inventory inventory = Inventory.GetInstance();
then read inventory.logCount in Start

[golden ermine]

can i do it somehow easier without doing singleton

[buoyant knot]

yes, but it’s harder because you need to manage references to things to avoid FindComponentInScene or something

singleton is the easiest way. You sure don’t want to keep two sets of counts of logs, right? And you definitely don’t want that in a static class

[swift crag]

why not make the player tell the campfire that the player is adding wood?

rather than having the campfire look at the player inventory

[buoyant knot]

campfire doesn’t exist yet

[golden ermine]

i dont get it how do u mean

like i have 2 prefabs of campfire

[swift crag]

doesn't matter. you wouldn't reference the campfire in advance anyway

[sage mirage]

Yes! I mean how can I use AudioSource.PlayOneShot() if there is a string name required as a parameter inside the method? Do I have to add those Sound Effects assets on my Hierarchy as objects and make tags for each one of them in order to get reference with the method above?

[swift crag]

you'd find the campfire when you mouse over it

or whatever you do to decide you're going to interact with the campfire

[buoyant knot]

campfire needs to access that data from somewhere

[swift crag]

i'm suggesting to invert this

Campfires should have no idea about my inventory

what are they doing in my backpack?

[golden ermine]

and when i have 3 wood collected and approach any of them it should take away 3 woods and change sprites and start animation as well as heal the player when isnide of trigger. While the other one can do the same only if i have 3 more wood

[buoyant knot]

either way, you need the link between the thing with the logs and the campfire

[swift crag]

The player should look for a campfire nearby and tell the campfire to light up

The player can then deduct 3 logs from their inventory

[buoyant knot]

and I would rather my inventory not know about the campfire, than the campfire not know about inventory

[swift crag]

Campfires that steal your wood sound a lot weirder than players that put wood in campfires

The inventory wouldn't know either. The inventory is an inventory.

The player notices the campfire and has an inventory.

void OnTriggerEnter(Collider other) {
  if (other.TryGetComponent(out Campfire campfire) {
    if (inventory.logs >= 3) {
       campfire.Ignite():
       inventory.logs -= 3;
    }
  }
}

Problem solved.

[buoyant knot]

there are a lot of ways to do this. not difficult

[swift crag]

I think this is the most natural way to do it, and also, conveniently, the easiest to implement

the campfire doesn't need to be made aware of your inventory

[golden ermine]

uh also i have this script that is attached to player, also when entered ontrigger it will make campfire https://hastebin.com/share/zolepomowa.csharp

[swift crag]

Instead of finding a campfire in the scene, just see if the thing you bumped into in OnTriggerEnter2D is a campfire

[golden ermine]

can i do that with if(collision.gameObject.tag == "Campfire")

[buoyant knot]

i don’t understand the difficulty here

[swift crag]

actually, looking at your code, you've already solved the problem more-or-less how I described

[buoyant knot]

when you collide/trigger, both things get references to each other

[swift crag]

the player notices a campfire, ignites it, and deducts 3 logs

maybe there is a miscommunication here

[polar acorn]

Use CompareTag, not ==
https://docs.unity3d.com/ScriptReference/Component.CompareTag.html

[buoyant knot]

player should have a reference to an inventory, and UI display should also have a reference to inventory

[swift crag]

yep yep

[buoyant knot]

this is why I thought it would make sense for inventory to be a singleton, unless it is a multiplayer game

[swift crag]

you're still using CampfireSpriteRenderer, which may not be from the campfire you just collided with

[swift crag]

That looks more reasonable. I'd go a step further and create a Campfire component that does everything for you

instead of doing a bunch of GetComponent calls

[floral wren]

Not really a good idea to have the inventory as singleton. You might want to have other character/object have an inventory.

[buoyant knot]

player should not have any knowledge of the campfire’s structure.

[swift crag]

bingo. encapsulation!

[buoyant knot]

player has no business setting animator flags

[swift crag]

the player knows how to tell campfires to ignite. the player doesn't care how the campfire works

encapsulation will prevent so many errors

[buoyant knot]

that’s why I specified. If there’s only one inventory in the game, singleton makes it easier. Otherwise, you need to get direct references for each player

[swift crag]

of course, you can always split the difference

inventories as non-static objects, but with a static reference to the player's inventory

[buoyant knot]

which would probably mean inventory would be a serializable POCO

[golden ermine]

Okay but how can I now make gameobject that is inside that campfire that i collided with set to true with in that if statemnet

[swift crag]

make a new script called Campfire

[floral wren]

It is more a question of potential growth of the game. It does not need to be multiplayer to be needing more inventory. You might want AI to behave with an inventory.

[swift crag]

It should have a reference to the animator and to the sprite renderer.

[golden ermine]

okay what then

[swift crag]

It should have a method that, when you call it, does all of the work needed to make the campfire light up

Then you can just get that single Campfire component and tell it to turn on

[buoyant knot]

only he knows his game’s needs. and if you’re making a really fixed single player game like mario, I argue it is actively worse to spend more time with a non-singleton. Goombas have no business keeping their own coin count

[swift crag]

Imagine you have lots of things that can ignite a campfire. If you decided to change how the visual works, you will have to change every single place that lights campfires

[golden ermine]

im making single player 2d top down game for school exam

[swift crag]

replacing GetComponent<SpriteRenderer>() with GetComponent<CoolNewThing>()

That's a hassle, and you'll probably miss something.

So, instead, just hide all of that logic inside the Campfire component

Change it once and you're golden.

[obsidian fern]

Does anyone have an idea how I could go about making an inventory system like the one in dredge? With puzzle pieces that can be rotated around to fit into each other

[buoyant knot]

Campfire needs its own Monobhevaiour, my man

[buoyant knot]

you probably want to use tilemaps. I have solved this issue before, but you are going to need a lot of math

[golden ermine]

okay can I do inside Campfire script like: public void Ignite() {inside this everything that it needs to do} and in playerMovement script in that if statement call it with collision.GetComponent<CampfireScript>().Ignite();

[rich adder]

are you talking about a grid inventory ?

[swift crag]

yep!

[obsidian fern]

Yes but for example an item could be in an L shape using 3 tiles

[golden ermine]

thanks, i will do that and then i will update u guys

[swift crag]

I have lots of really small components I only use in one or two places. They make my life simpler.

[rich adder]

yea thats called like Tetris inventory or something ?

many diff ways to do it

tilemap is interesting usecase too, never tried it though

[buoyant knot]

tilemap will work well. but you need math

[rich adder]

like everything else 😛

[swift crag]

I'm pretty sure this was a homework problem at my university

[obsidian fern]

I don't know how I'm going to learn how to do this

[buoyant knot]

you need an SO that has information about the position of each tile.

[rich adder]

https://www.google.com/search?q=Tetris+inventory+unity

some good stuff

[timber tide]

Easy way is to just check neighbors of the 2D array

[rich adder]

seem codemonkey has one, just be careful with codemonkey code xD

[buoyant knot]

you need a function to rotate the coordinates of each tile, and output a shape.
and you need a function that can look into the tilemap and retrieve the SO

[rich adder]

eh why would u use invoke repeating?

[solar heron]

Can someone help me, im trying to update the InvokeRepeating method because im trying to make my mobile clicker game clicks counter go up

[rich adder]

jesus..

use a coroutine

[buoyant knot]

yeah

[obsidian fern]

Seems way over my head. But this is unfortunately my goal

[timber tide]

it's basic array navigation

[solar heron]

yeah my code is crap XD

[buoyant knot]

I would not store all that info into playerprefs

[rich adder]

lol its fine. what are you trying to do though exactly?

[golden ermine]

is this okay

[buoyant knot]

you would want to store the counts of everything into a JSON/BSON

[rich adder]

I love bson

i use mongo and bson is fun to work with

[solar heron]

So basically, im trying to make the money counter go up 1 by 1 but fast per Money Per Second. and im stuck because i cannot update the invoke repeating method

[buoyant knot]

if someone is determined enough to look up the save file and edit it, they are determined enough to figure out how to read it

[rich adder]

yeah you would want to use a coroutine so you can modify the same one or stop it, etc.

[buoyant knot]

good. you should not invoke repeating

[solar heron]

Oh okay ill try, i never used a couroutine but ill try!

[rich adder]

https://docs.unity3d.com/Manual/Coroutines.html
https://docs.unity3d.com/ScriptReference/MonoBehaviour.StartCoroutine.html

StartCoroutine returns a Coroutine

[buoyant knot]

I would make an SO with details about a specific type of thing: name, click frequency, reference to sprites etc.

[golden ermine]

is now everything fine?

[buoyant knot]

then make a single component that takes in info from that one coroutine to start running it. I expect you only need to define one IEnumerator to make your code work

[rich adder]

campfire healing? are you making terraria

[golden ermine]

lmao

i made that script before but didnt used it so i just used it now, i didnt bother to change a name lol

[rich adder]

its a good name

tells you what it does

[buoyant knot]

i would just call it campfirep

and then give it responsibility over anything a campfire needs to do

[rich adder]

CampfireController

[golden ermine]

also can i move that if statement from playermovement script inside campfire script so that when player is inside campfire trigger it will lit not when campfire is inside of player trigger

[buoyant knot]

because changing the animator to IsLit has nothing to do with healing

[buoyant knot]

that is correct

player has no business knowing anout the inner workings of campfire

[golden ermine]

also can i add to if statement (Input.GetKeyDown(KeyCode.E) && everything else) will that work so when im in trigger and then press e it will lit

[buoyant knot]

player knows about player

[golden ermine]

or maybe put first if statement inside that input.getkeydown(keycode.e)

[uncut veldt]

Hi quick question im having a problem with rotation as i have a motorbike in a project and i want to aplly lean to counteract the wheel collider lean as that leans in the wrong dirrenction i am currently using this to do that ow wver it doesnt work as intended at all cs transform.rotation = Quaternion.Euler(new Vector3(transform.rotation.x, transform.rotation.y, -Mathf.Clamp(leanCoeffitient * frWheel.steerAngle, -maxLeanValue, maxLeanValue))); any help is apreciated

[buoyant knot]

you also do not want to write the number 3

you want to use private const int, and define 3 at the top

[solar heron]

    private void Update()
    {
        StartCoroutine(GiveMoneyPerSecond());
    }

    IEnumerator GiveMoneyPerSecond()
    {
        yield return new WaitForSeconds(time / MPS);
        money += 1;
        PlayerPrefs.SetFloat("money", money);
    }
``` uh is this good XD

[buoyant knot]

especially for school, I would dock you for putting that magic number 3 randomly in your code

[solar heron]

nope i guess not its wayyy to fast

[buoyant knot]

do not start a coroutine in every update lmao

that starts a coroutine every frame

[golden ermine]

is this script now all good?

[solar heron]

I want it to be once every time / MPS

[buoyant knot]

also stop using playerprefs like that

[rich adder]

put it in start where it was

[wintry quarry]

looks like an immediate null reference exception with playerUI since it's private and never assigned

[uncut veldt]

you could use InvokeRepeating or you could add a bool to the iEnumerator and only ollow the code to run every x seconds thats what i do anyway

[rich adder]

use TryGetComponent instead

[buoyant knot]

definitely not

getkeydown is true for one frame when you press a button

[golden ermine]

ontriggerstay then?

[buoyant knot]

nope

[rich adder]

yes also dont put 1 framebuttons

in trigger enter

[buoyant knot]

those trigger callbacks happen once every physics frame

[timber tide]

Basically, designate a pivot for your items and inventory. Preferably the most top left index would be [0][0] of each of them. In your item's data, make an array of vector2Int. Now, say a dagger takes up 3 spaces vertical, then your array of vector2Ints would be [0, 0], [0, 1], [0, 2]. Now, when you pick up the dagger, first scan from the top left to the bottom right of your inventory. When you find an open space, take that index and try finding open indices for all of your dagger. If the open inventory index is [2, 0] then you now make this the pivot and add/check if your dagger fits at this space so add your Vector2Ints with this value each -> [2, 0], [2, 1], [2, 2]. If each slot is empty, add the dagger, otherwise search for the next open slot and redo the vector3Int addition and check operation.

[golden ermine]

when then

[rich adder]

ideally you make a bool you toggle in update

only use bool in Trigger

[buoyant knot]

i use input system, but that’s beyond him rn I think

[rich adder]

yes

[buoyant knot]

i think GetKey tells you if the key is currently pressed, not necessarily this frame

[golden ermine]

how to fix

[edgy prism]

.gameObject

[buoyant knot]

also, you need ontriggerStay, probably

[cosmic dagger]

what does the error say?

[rich adder]

this wouldn't set it back to false tho

[rich adder]

isEPressed = Input.GetKeyDown(KeyCode.E)

[buoyant knot]

you need to stop guessing and asking us

[rich adder]

if(TryGetComponent(out PlayerUI playerui))

[cosmic dagger]

again, posting the error helps. that's not how you use TryGetComponent . . .

[swift crag]

why is the campfire talking to the inventory?

[edgy prism]

mr Navarone I have a bone to pick with you

[swift crag]

I suggested making the player tell the campfire to ignite.

[rich adder]

oh uh that dont sound good

[swift crag]

It should be a very simple class

[buoyant knot]

right now, we tell you X is wrong, and then you make some haphazard change immediately. You will not learn unless you take a moment to think

[swift crag]

public class Campfire : MonoBehaviour {
  public Animator animator;
  public SpriteRenderer spriteRenderer;
  public Sprite ignited;

  public void Ignite() {
    animator.SetTrigger("Foo");
    spriteRenderer.sprite = ignited;
  }
}

This is all the campfire should care about.

[swift crag]

when you tell it to turn on, it turns on.

[edgy prism]

Hahha you remember a few days back we were talking about inky? I have spent all of today and more of yesterday than I care to admit trying to figure out how to implement it in my code

[swift crag]

you're creating needless complexity by making the campfire try to find and reason about the player's inventory

[rich adder]

wait really? did you look up other tuts. this guy trever or w/e really helped me

https://www.youtube.com/watch?v=vY0Sk93YUhA

[edgy prism]

Yeah I mean it works great other than me being stupid

[golden ermine]

but still if i do it in campfire script it will work but its more complicated?

[swift crag]

anything can work

[buoyant knot]

there are multiple issues here. And it’s not the code being in the campfire class

[rich adder]

this guys video helped me greatlly on this, he also has Portraits and names features.
Not sure why the link isn't embedding the video but you can click it

also this one https://youtu.be/tVrxeUIEV9E?

[golden ermine]

okay guys this is what it looks like now, so first issue is why is trygetcomponent not working

[swift crag]

because that's not how you use it, full stop.

[rich adder]

because u aint using it correctly

[swift crag]

you should read the documentation

you can't just mash random words together and get a working program

[rich adder]

that and Ive shown you example

twice

[swift crag]

https://docs.unity3d.com/ScriptReference/Component.TryGetComponent.html

[rich adder]

the doc does suck for TryGet

not gonna lie

I sent in a "Report issue with this page"

[swift crag]

what is the problem?

[cosmic dagger]

that's not how you use TryGetComponent. you can look at the !docs for an example or look at this: #💻┃code-beginner message

📖 Manual

[rich adder]

the use reduant <T> when you can just pass it in the ( out Rigidbody rb)

[swift crag]

i noticed that the old docs don't do that

the generic type is implicit

[edgy prism]

Thanks I will give them a watch and see if that helps my current issue is more or less just that im doing everything in coroutines and once story.canContinue is false Im crying

[rich adder]

yeah its weird, hopefully they fix it lol

also would be nice to show that you can also use it if you already have a non local var

[cosmic dagger]

yep, weird they added it in there . . .

[eager elm]

that's also pretty advanced for beginner code, just use GetComponent() and check for null

[swift crag]

i would not call TryGetComponent "advanced"

it has an out parameter, I guess

[rich adder]

Rigidbody rb = null;

if(TryGetComponent(out rb))

they also missed this example

[golden ermine]

i know this is incorrect but i dont understand it by that document

[cosmic dagger]

Try methods are not advanced at all. they are common . . .

[rich adder]

you see PlayerUI is darkgreen

it means its reduant

[golden ermine]

yes

[swift crag]

This is valid code.

[rich adder]

you can remove <PlayerUI>

[swift crag]

It's not exactly what you intended, though.

It is storing the PlayerUI object it found into the woodCount variable

[cosmic dagger]

you can remove the grayed (darkened green) PlayerUI between the angle braces . . .

[swift crag]

if (playerUI.gameObject.TryGetComponent(out PlayerUI ui)) {
  // the ui variable isn't going to be null in here
  if (ui.woodCount >= 3) {
    ...
  }
}

This is a valid usage.

The method returns true if it finds the component.

You can then use the component inside the if block.

If the component is not found, the block is skipped.

[eager elm]

the entire code is unnecessary though, just change

GameObject playerUI to PlayerUI playerUI

[swift crag]

that would also be reasonable, yes.

I almost never reference a GameObject

I always want something more specific

[rich adder]

just to recap

PlayerUI playerUi;
if(playerUi != null)
playerUi.stuff```
is the same as 
```cs
if(TryGetComponent(out PlayerUI ui))
ui.stuff```

[swift crag]

That ought to work! I would break the big line up into smaller chunks.

But it looks fine to me.

[golden ermine]

Okay thanks guys, also did i fix bool that says when e is pressed. Cause i dont see why it shouldnt work lol

[rich adder]

nah do it like i suggested @golden ermine

#💻┃code-beginner message

[eager elm]

your playerUI is also not assigned anywhere, you might want to make it public and assign it in the Inspector

[golden ermine]

i cant cause campfire is an prefab and playerUI is in game scene

[rich adder]

you're gonna get null reference exception then

[golden ermine]

how to fix it

[rich adder]

make it not null

[golden ermine]

yea but how can i assign it when its in prefab

[rich adder]

depends why does campfire care about UI in the first place

some type of unity style dependency injection, pass the component through method from whoever has the reference

[golden ermine]

cause in playerUI script i count how many wood i have

[rich adder]

then it should be a static instance of a class that tracks your inventory

the UI should not care about logic

[golden ermine]

i know but its not only ui i named my script wrong

[rich adder]

and your stats should be public /singleton available

[rich adder]

time to start using clearer names

[golden ermine]

they are public

[rich adder]

you need a singleton

so you can make it static

then you just access stats when you need them

PlayerUI.Instance.wood

or w/e

[rich adder]

right

so you need to just assign it

this isn't needed

and the other one in if statement trigger

[rich adder]

looks good

tryget is useless now

and still doing it on a null obj

[rich adder]

did you assign the instance

to the PlayerUI

[golden ermine]

no where to assign it

[rich adder]

in awake of playerUI

private void Awake()
    {
        if(instance != null && instance != this )
        {
            Destroy(gameObject);
        }
        else
        {
            instance = this;
        }
    }```

[golden ermine]

okay i did it

thank you it works now, now i can have as many campfires as i want haha

[rich adder]

next step.. Putting your stats into a struct / class

🙂

[golden ermine]

😟

[rich adder]

haha that comes later tho, you did well so far

quick learner

using class /struct will just help you group stuff together

[golden ermine]

hahah thanks

okay

[sand veldt]

i think its a dum question but is it necessary to clear a list or we can set it to null

private void table_OnTableSitEvent(object sender, Table.KitchenObjectSOsEventArg e)
{

    kitchenObjectSOs=null;
    kitchenObjectSOs = e.kitchenObjectSOs;
    CreateUIIcons();

}

[wintry quarry]

the first line is not necessary at all

[sand veldt]

i dont want to clear data from the real list

[wintry quarry]

kitchenObjectSOs = e.kitchenObjectSOs; is sufficient

kitchenObjectSOs=null; can be deleted, as it is simply overwritten on the next line

it's kind of like

int x;
x = 5;
x = 3;
print(x);```

you don't need the x = 5 line, it adds nothing of value.

[pine abyss]

Hello folks!
Weird question. Would anyone have any idea how to use the SetLookAt IK function to rotate an animated head of an avatar based on mouselook? I know how to make it rotate with regard to another GO, but based in mouse? That's too much for me... thanks! ❤️

[sand veldt]

ok thanx

[wintry quarry]

use the mouse input to move some other object that the IK is looking at
