[rich egret]

no answer

[wintry quarry]

none of those are the log you just wrote

that means your raycast is not hitting at all

[polar acorn]

Is that all of the logs?

[wintry quarry]

or the code is not running at all

[rich egret]

yup

[polar acorn]

Then we have definitely shown that your raycast is not hitting anything at all

Meaning there is no object within 1 unit of the front of shootingPoint with a collider

[wintry quarry]

raycast default distance is infinity

[polar acorn]

Ah, right

[rich egret]

The balls are deleted after 5 seconds

[polar acorn]

DrawRay is the one where the distance is baked into the direction

[wintry quarry]

the balls are completely irrelevant, you're using a raycast

[polar acorn]

So, either CanShoot() is never true, or the raycast never hits anything because there's no colliders in front of shootingPoint

[polar acorn]

If the balls exist at all then the raycast is hitting something and you'd get the log

[rich egret]

https://gdl.space/zaliqugoqa.cs
this is the code

[polar acorn]

so either you didn't save, something else is spawning them, or the balls are not the bullets and you've just given me a random non-sequitur

[rich egret]

They exist, but I did something that a bullet can't pass through something "solid" is this related?

[polar acorn]

The actual spawned bullet object has nothing to do with your raycast which is what calls the damage function on the enemy

so it doesn't matter what they collide with

[rich egret]

ok

[polar acorn]

Since the log is before the Instantiate line, if that line is running at all then the log is going to the console

If it's not, then you probably didn't save the script before starting the game

[rich egret]

I just need an idea to solve it

bro what

[polar acorn]

Okay, there we go

Does PlayerBody have the Enemy tag

[rich egret]

I could swear I saved it!

[rich egret]

yup

ah no

[polar acorn]

Show the inspector of PlayerBody

[rich egret]

The only one who has an enemy tag is the "doll".

[polar acorn]

So then your code is doing exactly what it's supposed to be doing.

The ray didn't hit an enemy so it doesn't damage the enemy

[rich egret]

i know

so what to do?

And I forgot to say thank you, it goes without saying that you help me

[polar acorn]

Is the ray supposed to be hitting PlayerBody

[rich egret]

no.

It's literally the player

[summer stump]

You either want to use a layermask to disclude the player, or have the raycast start in FRONT of the player instead of inside it

[vernal minnow]

Is it better to do damage in whole number increments or float decimal increments?

[frosty hound]

Whatever makes sense for your game

[polar acorn]

Do you want damage to be in whole number increments or float decimal increments?

[vernal minnow]

I'm not yet sure, I plan to show health as X/100 but having defense on the character could divide damage into decimals

Although I'm kinda thinking that having defense divide the damage doesn't make much sense

[ionic topaz]

As said before it depends on the game but generally I feel like most games would round it to a full number (visually to the player not in the code)

[vernal minnow]

Its an arcade game so honestly it should probably be whole numbers and the defense should just directly subtract from the damage

Thanks 😂

So how do I convert integers to strings to show tye number in the text?

[rich adder]

imagine if you typed the same thing into google

[ionic topaz]

I believe you can do something like "Health: " + yourIntHere

[vernal minnow]

Is it the ${x:2}?

No... that doesn't look right

[rich adder]

You can use $ sure

[vernal minnow]

Something similar tho

[rich adder]

but how you wrote formatting is wrong :

[summer stump]

$""
You still need the quotation marks
You are doing "string interpolation" which you can google for more

[vernal minnow]

Alr, thanks

[rich adder]

string text = $" health : {healthVar}"```

[ionic topaz]

huh, never seen that before

[rich adder]

google "String interpolation"

[desert elm]

what are quarterions

[rich adder]

rotations

[wintry quarry]

Just a variable that holds a rotation

[summer stump]

4 values as a struct.
x y z w

[desert elm]

oh okay-

wait how do they have
4 different axis?

[wintry quarry]

no

don't worry about it

it just holds a rotation with some fancy math

[summer stump]

Not 4 axes
3 axes represented by 4 VALUES

You don't really work with quaternions directly

[vernal minnow]

Stop, w was literally a question

[wintry quarry]

you don't ever need to look at or care about those 4 numbers

[vernal minnow]

Whys the server messing with me?

😂

[wintry quarry]

just think about the whole thing as an opaque box that holds a rotation

[ionic topaz]

0.0 don't speak the forbidden language more

[desert elm]

okay- uh
if I just want to have a 2Dgameobject turn to face a vector2
can I use quarterion.slerp?

[wintry quarry]

myObject.right = direction;

[wintry quarry]

you can Slerp the direction vector

[desert elm]

right?

[rich adder]

yes because those are spammy and unecessary

[vernal minnow]

So what rotation is w then?

Or is that 3d?

[rich adder]

all 4 numbers make a rotation

[short hazel]

It's not a rotation

The whole quaternion is the rotation

[wintry quarry]

none of them are rotations around axes. Again, don't worry about the actual 4 numbers unless you want to spend 3 hours doing math lectures. Just think of the whole thing as a variable that represents a rotation, that's it.

[short hazel]

As long as you use the stuff in the Quaternion struct, and not interpret the XYZW as individual angles in degrees, you're fine

[summer stump]

Xyz represents a direction, w is the amount of twist around that direction

[rich adder]

^ Unity has Quaternion methods in it so you only need to work with Euler angles

[vernal minnow]

I'll pretend they don't exist till I need them ig lol

[summer stump]

You won't need them. Ever

[ionic topaz]

quaternion.euler and quaternion.identity are the simple ones you'll be using most likley

[rich adder]

just worry about euler angles

[vernal minnow]

I've used quaternion once already though

[summer stump]

Not directly
You may have BUILT one from Eulers?
Not the same thing at all

[swift crag]

you need quaternions

you just don't need to fiddle with their values

just like you don't fiddle with a Transform's 4x4 matrix

[summer stump]

Ok fair fair haha

[desert elm]

what does .right mean int this case?

[swift crag]

I don't mess with the Matrix4x4. I mess with position, rotation, and scale.

[wintry quarry]

the right direction of the object

the red arrow in scene view

[desert elm]

oh okay-

direction is a vector 2 position?

[vernal minnow]

GameObject laser = (GameObject)Instantiate(CirclePrefab, firePoint.position /*+ new Vector3(0.0f, 0.0f, 0)*/, itGuy.rotation /*Quaternion.identity*/);i was using it in two projects, what do you mean building it?

[swift crag]

That question doesn't make sense to me.

A direction is a Vector3.

transform.right will be a Vector3 with a length of 1.

[vernal minnow]

stopped using it bc i didnt understand em

[swift crag]

Aeth was talking about trying to manipulate the underlying data that a Quaternion is made from.

Don't worry about that at all.

[vernal minnow]

Ah

[swift crag]

It's just a common error to mistake it for euler angles

[summer stump]

I was talking about w specifically, which you were asking for

[vernal minnow]

What's an euler angle?

[swift crag]

transform.rotation.x; // not x rotation
transform.rotation.y; // not y rotation
transform.rotation.z; // not z rotation
transform.rotation.w; // ???

Euler angles are the X/Y/Z rotations you're more familiar with

It's what you see in the inspector

They produce a rotation by spinning around three different axes.

[wintry quarry]

euler angles are a way to express rotation via angles around the x y and z axis

[vernal minnow]

Uh... looks like I need to have a look at my inspector again...

Oh wait

[swift crag]

They have worse mathematical properties than quaternions, which is why Unity uses quaternions at all

[polar acorn]

The rotation in the inspector is local euler angles

[vernal minnow]

Those 🤦‍♂️

[swift crag]

(which is transform.localEulerAngles ! )

[vernal minnow]

Interesting, what would that actually do though?

[swift crag]

well, it gives you the local euler angles of the transform

the rotation you see in the inspector, as digi said

similar to transform.localPosition and transform.localScale

those are what the inspector shows you

[wintry quarry]

it doesn't do anything, it's just information

[vernal minnow]

Holy crap, so I can save that in a variable to reuse later?

[swift crag]

well, sure, if you needed that

[polar acorn]

It... it displays the value of localEulerAngles

[wintry quarry]

sure but you could also save the more effective thing which is the rotation or localRotation Quaternion

[wintry quarry]

welcome to programming

[desert elm]

what transform direction is the green line in the scene view? forward?

[polar acorn]

up

blue is forward

[desert elm]

even in 2d view?

[polar acorn]

yes

[desert elm]

okay, thanks

[rich adder]

your forward here is transform.up

[swift crag]

Yeah, it's a little annoying for 2D

you have to decide which direction is going to be your "2d forward"

[desert elm]

whats the inverse?

[swift crag]

-transform.up

[desert elm]

oh

[swift crag]

there is no transform.down, alas

[polar acorn]

negative up

[swift crag]

Unity 6 feature? 🥹

[rich adder]

they do it for Vector3 but got lazy with transform

[north kiln]

Is this what your IDE looks like, or is this a screenshot of a website 🤔

[desert elm]

IDE?

[north kiln]

!ide

[eternal falcon]

💡 IDE Configuration

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

Select one:

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

[polar acorn]

the thing you type code in

[desert elm]

oh no its the IDE

it autocompletes yes

[polar acorn]

then you need to configure it

[rich adder]

doubt

[desert elm]

well, it did previously

oh nevermind

[north kiln]

does it really autocomplete? If it's not underlining errors in red it needs to be configured

[desert elm]

it is underlining errors

just not autocompletting now I assume

its 3am anyway and I got other work to do

[short hazel]

Completion is context-aware
If you're typing stuff outside of a class, you won't get many suggestions

[rich adder]

so is just a shitty theme then here ? why its all white lol

[short hazel]

Normal if all of these are fields/properties

[desert elm]

they are all variables

[short hazel]

direction and directionNormalized should be local variables. They'll be light blue if that's the case

[north kiln]

I would hate to use a color scheme that bad lol

[short hazel]

It's the default for VS

But a rare sight, since you use more methods and locals in methods

[rich adder]

props usually was bolded for me at least

[short hazel]

Then you modified it in the settings

[north kiln]

I watch a youtuber who has Rider set to the default VS color scheme and it makes me angry every time I see it lol

not being able to tell a value type from a reference type 😞
properties same color as local variables 😞

[short hazel]

Correctly naming things also helps in distinguishing what is what, but oh well this is Unity, can't have everything

[short hazel]

That was VS2017's (and before) theme. Now these can be differentiated

[lofty sequoia]

Does Rider let you set a color for a file tab?

[rich adder]

prop local and method parama

[north kiln]

Don't think so; it lets you set colors and icons for projects, but files, not that I'm aware of

[lofty sequoia]

looks like vs2022 lets you do that finally

[desert elm]

is there a way to write "or" in if statements like
if ( bool == true "or" bool2 == false)
{

}

[slender nymph]

have you googled it

[polar acorn]

Yes use the or operator

[desert elm]

nvm I have googled it

[vernal minnow]

Im having an issue with using a variable from another text, for some reason i can test integars but cant seem to use strings

wait...

its not in update... mb

ok im still having the issue and its now trying to create a tupple

void Update() { if (script.speed == 6) { Debug.Log("Speedboost active"); } healthtext = script.playerhealth; }

its properly checks the integer so im not sure why a string wouldnt work similarly

public string playerhealth = ($"{health}"); unless this is just formatted wrong?

[slender nymph]

that is 100% not formatted correctly

first of all, that would only create the string at the time the object is instantiated. so the value won't update. and then you also have the () around it which is likely what is causing your error

[vernal minnow]

is this only for floats?

[slender nymph]

no, you can use string interpolation anywhere. but strings are immutable so this won't update with the health variable

but also why is that a string?

[summer stump]

public string playerhealth = $"{health}";

[vernal minnow]

why is what a string?

[slender nymph]

why is playerhealth a string

[vernal minnow]

health is an integer, dont i need a string to input into a text?

[slender nymph]

well you could use string interpolation at the time you need to create the string. or you can call ToString on any object (including ints)

[vernal minnow]

tostring didnt work either

i tested it too

[slender nymph]

but it seriously seems like you have a tenuous (at best) grasp of c# and i would suggest going through some beginner c# courses to learn wtf you are doing

[summer stump]

I mean, it WILL work if the syntax is right
You had parentheses around the string though, did you do the same with ToString() ?

[vernal minnow]

public string playerhealth = health.ToString();/*$"{health}";*/

[summer stump]

See, you're doing it in the initializer...

Why?

[vernal minnow]

im doing it in update

[slender nymph]

so you remember how i just said that strings are immutable so they won't be updated along with your health variable?

[summer stump]

You can't have "public" in Update

[polar acorn]

If that line is in update then you will need to fix that compile error

[vernal minnow]

so i need to initialize it before i can use it?

well before i can update it?

[polar acorn]

Why do you even have a string variable at all

[vernal minnow]

so that i can use this textmesh thing

still learning how textmesh pro works but i assume it still needs a string

[summer stump]

Just pass health in, no need to make a separate string variable
Just like legacy text.

[polar acorn]

Just use the health variable

[vernal minnow]

integers work in the texts?

[rocky canyon]

.ToString()

[polar acorn]

Yes but also you've been told like nine different ways to convert it into a string when you need it

[vernal minnow]

again, tostring did not work unless you mean text= variable.ToString();

[polar acorn]

ToString absolutely works

[summer stump]

Again, you did it in the initializer, which is why it didn't work

You do it when setting the text value.
Not before

[vernal minnow]

fixing now btw, i keep getting sidetracked

well now its trying to say im converting a string to textmesh pro...

but thanks for the first fix

[summer stump]

textObject.text =

[vernal minnow]

yep, forgot .text

[summer stump]

You have to access the text property before setting

[barren loom]

using UnityEngine;

public class AlienMovement : MonoBehaviour
{
    [SerializeField]
    private float screenBorder = 30;

    public float moveSpeed = 1.0f;
    public Rigidbody2D rb;
    public float maxVariability = 4.0f;
    public float minVariability = -4.0f;

    private Camera camera1;

    private void Start()
    {
        camera1 = Camera.main;

        // Generate a random variability within the specified range
        float variability = Random.Range(minVariability, maxVariability);

        // Set the velocity based on variability
        rb.velocity = new Vector2(variability, 0) * moveSpeed;
    }
    private void FixedUpdate()
    {
        reverseVelocity();
    }

    /*
     * Checks if the Alien is near the border
     * Changes the direction to the opposite way if the Alien hits the border
     */
    private void reverseVelocity()
    {
        Vector2 screenPosition = camera1.WorldToScreenPoint(rb.position);
        if ((screenPosition.x < screenBorder) || (screenPosition.x > camera1.pixelWidth - screenBorder))
        {
            //Reverses the direction
            rb.velocity = new Vector2(-rb.velocity.x, 0);

        }
    }
}

I'm trying to reverse the velocity of the gameobject after it touches the border of the screen. However, the gameobject does reverse in the unity editor but stays at the border after being built.

[slender nymph]

you do know you have to actually describe what isn't working for anyone to know how to help you, right?

[barren loom]

oh mb

the alien just stops at the screen border

[rocky canyon]

i was going to just say Interesting.. :0

[barren loom]

instead of reversing

[rocky canyon]

may have something to do with ur hard coded screenBorder? edit: then again idk, maybe build a development build with debugs in ur methods

[queen adder]

hello

[barren loom]

uhh, can you specify how I would the get the actual screenborder value?

[rocky canyon]

isnt there a screenwidth or something?

[barren loom]

Let me try that out rq

setting

screenBorder = Screen.Width just makes the gameobject stay in place

[vernal minnow]

yeah... everything that i had learned a few months ago was either incorrect or just outdated so im in the process of fixing what i had in my last two projects and learning new things that ive never used before

up until last week, i didnt even know text mesh pro was a thing and tried to argue why i used legacy instead of trying it🙄

[slender nymph]

i wasn't even referring to unity stuff though. i was referring to the fundamentals of c# which includes things like accessing variables and methods from other objects, converting things to strings, and syntax

[vernal minnow]

yeah, i just learned how to access other scripts today, my last two projects had most of the code in a single c# file

didnt end well

[rocky canyon]

i may have mistaken what ur trying to do. i was just saying by using screewidth u can calculate when u reach each side something like this came to mind ```cs
void Update()
{
CheckScreenEdges();
}

void CheckScreenEdges()
{
    Vector2 screenPosition = mainCamera.WorldToScreenPoint(transform.position);

    if (screenPosition.x >= screenWidth)
    {
        rb.velocity = new Vector2(-moveSpeed, 0);
    }
    else if (screenPosition.x <= 0)
    {
        rb.velocity = new Vector2(moveSpeed, 0);
    }
}```

[rocky canyon]

not sure why it would work in the editor but not in build

[barren loom]

Hmm, alright

[misty hedge]

If I have a DialogueEvent that extends from the abstract class Event but has a field (string Line) that is not in Event, how I access this field from a List of type Event? I tried casting to DialogueEvent but that did not seem to work.

[shell herald]

idk if this is the right thing, but is it possible to have an "if" with 2 variables?
so

if(bool1 and bool2)
{

}

[north kiln]

one could google "C# and"

[gaunt ice]

Google logical operator

[misty hedge]

(it's &&)

[plush chasm]

I think casting should work.. are you sure you were using the casted variable I think like this.. ((DialogueEvent)eventList[0])).Line

[misty hedge]

No, I tried explicitly casting it to see if that'd let me access that field.

[slender nymph]

you're missing some parentheses to make it work

[plush chasm]

yeah you aren't useingthe casted variable

[slender nymph]

((DialogueLine)events[i]).sLine

[plush chasm]

((DialogueEvent)eventList[0])).Line

[misty hedge]

SIGH

Yep, that did in fact work.

Very silly oversight, thank you!

[slender nymph]

or instead of using that terrible sType variable, you can instead use the is operator to type test it and put it into a local variable all at the same time

[plush chasm]

I have had that problem many times

[slender nymph]

if(events[i] is DialogeLine dialogueLine)

[misty hedge]

oh! that's even better

[late burrow]

does transform worth referencing if i already have other component and can just .transform

[slender nymph]

not really. it's a micro optimization at best so just accessing the component reference's transform property is perfectly fine in nearly all cases

[delicate slate]

can anybody help me out

[summer stump]

Maybe. No one can say without hearing the issue

https://dontasktoask.com/

thank you for the advice

[keen crescent]

In my game, I'm using ScriptableObjects to create projectiles, which has worked well so far. (For example, each projectile accesses a scriptableobject to get its sprite, properties, etc.) But I want to be able to add a ParticleSystem component to them at runtime, but I don't see a way to store that using a ScriptableObject
Should I just be using prefabs or is there a way to make this work?

[timber tide]

you can store particle system assets onto the SO

wait maybe im thinking of vfx graph sec

[keen crescent]

I can technically generate a field for one, but there's no way to populate it with a stored asset since a ParticleSystem is a component that has to be attached to an object

[timber tide]

ah yeah it's connected to a GO as a component

so prefab is the idea

[keen crescent]

ah that sucks

[delicate slate]

it worked thank you

so much

[livid tundra]

I have some steep stairs that I need my character to run down from the top instead of flying off the top like the General Lee

(The car from Dukes of Hazard, not the...you guys get it)

I need to make a system to constrain her on the way down while she is in the Move state

[frosty hound]

You need to apply force in the direction of the slope, rather than applying it directly forward

[livid tundra]

by that logic, I should turn off gravity too

[frosty hound]

Sure

Also please don't crosspost #🔀┃art-asset-workflow

[livid tundra]

I'll delete my musings for this situation there

[frosty hound]

It's fine, just a future point

[livid tundra]

so right now she can climb the stairs and stay stationary because I am toggling player.rigidBody.isKinematic on Enter/Exit of Idle state

you are proposing (if I understand) that in the Move state, when I am slopeDetected(), I manually override the velocity vector?

[frosty hound]

That sounds messy in general

I would just add the force in the slope direction regardless of how steep it is. Even on flat ground, you're on a slope.

[nimble apex]

currently i need to reassign shader and reconfigure properties of a material, due to our project architecture and approach, we cannot pre-assign the material/shader to the gameobject , in order to get things done , i need surface type to set to trasparent

so, my question is, what are the shader keyword for "surface type"

somehow this is not working, surface type hasnt changed at all

[livid tundra]

are you talking perpendicular to the stair surface or parallel to the stairs surface?

Also, does one of the basic C# libraries have a constant sqrt(2) predefined?

[frosty hound]

Parallel to the surface of the ground below the player

[livid tundra]

I assume that by "Force" you mean "velocity"?

b.c. I don't know where I can apply a force on the rb

[frosty hound]

You can use AddForce on a rigidbody, or you can modify the velocity directly

[buoyant knot]

if you have a dynamic RB, I strongly recommend against directly modifying velocity until you have more experience

because directly modifying velocity quickly leads to spaghetti code when multiple scripts try to do the same thing

[odd mason]

im not sure what is wrong with the class anyone know?

[north kiln]

https://unity.huh.how/script-loading-issues try these solutions

[livid tundra]

I need to get the dot product of a raycast with a collider's normal, does anyone know how to get that?

[north kiln]

What are you struggling with? You just use the dot product on both of those variables, the hit has the normal, and the ray has the direction

[odd mason]

instantly found a solution thanks so much

[livid tundra]

oh, maybe I am overcomplicating

I just want to check if a raycast is hitting normal or not

[gaunt ice]

Normal is not a point

[livid tundra]

I know, I didn't say it was a point

I want to turn something on or off depending on whether my slopeCheck raycast is intersecting normal to a surface or not

(in 2D)

[north kiln]

still not sure what the difficulty is, just get the dot product and compare it to whatever bias you want

[livid tundra]

dot product of what and what else though

[gaunt ice]

I think he doesnt know what normal is

[livid tundra]

I have a bachelors degree in Math, I know what a normal vector is

[north kiln]

You just use the dot product on both of those variables, the hit has the normal, and the ray has the direction

What are you struggling with

[livid tundra]

🧐

[livid tundra]

the stairs problem ^ a few posts up

[gaunt ice]

The normal in unity is exactly what you learn in uni

[frosty hound]

(Get the normal of the ground below the player, and use the cross product to get the slope)

[gaunt ice]

Raycast intersects with triangular mesh at point and normal tells you what is the direction of the triangle facing to

[livid tundra]

I'm not confused about what it is

[north kiln]

Great, then what is confusing you? Because I've explained what two things you care to dot product, the exact same two things you mentioned right at the start

[gaunt ice]

Google raycast hit info and read the properties

[livid tundra]

ok, I'm going to do that

[round scaffold]

aw i love interact systems

[livid tundra]

Ok, I don't want to do a second raycast to get the normal when I am already doing that to get a bool

I want to keep the raycast2D I am already doing as is and access its normal

I know how to do that

but right now it is being casted as a bool per the tutorial

[gaunt ice]

Raycast has overloaded method to get back the hit info

[livid tundra]

how do I get the true/false info from a raycast2D?

because I need to revise my existing code to only access that part elsewhere

if I keep it as a Raycast

[gaunt ice]

Just google or your ide will tell you how the overload methods look like (signatures)

[livid tundra]

yes, I was just looking at it but I don't see a bool

[north kiln]

Pretty sure you just use it in an if statement, or if that doesn't work just compare its collider with null

[gaunt ice]

Your ide should show you
public return_type same_method()
public other_return_type same_method(int some_int)

[livid tundra]

ok I got it now

[fresh trellis]

i can't drag sound audio mp3 into the unity why?
public AudioSource doorSound;

[livid tundra]

the struct

[north kiln]

An AudioSource is a component

[storm shore]

https://paste.ofcode.org/35aY9ACXbyXSUuafN5x2FMM

This code is supposed to change a shader material values over time and it works for the mesh renderer component but i also want to use it on a skinned mesh renderer and don't know how to do it. Can someone tell me how you can do this.

[north kiln]

Are you looking for AudioClip?

[livid tundra]

public static implicit operator bool(RaycastHit2D hit);

🤔

[fresh trellis]

i need if i open door i got sound of door

[gaunt ice]

No, you should look at the method signatures of raycast

[fresh trellis]

i can't drag my sound door in my unity idk why

[north kiln]

They found what they were looking for, you're not thinking of the same thing. Physics2D doesn't have an out the same way Physics does

[gaunt ice]

Forgot, mb

[fresh trellis]

hey. any help?

[north kiln]

I explained your issue.

An AudioSource is a component, are you looking for AudioClip?

[fresh trellis]

yes

[livid tundra]

:D

public override void Update()
{
    base.Update();

    player.SetVelocity(player.moveSpeed * xInput, rb.velocity.y);
    if (xInput != 0 && player.IsSlopeDetected() && player.IsSlopeDetected().normal != Vector2.up)
    {
        player.rb.velocity = new Vector2(xInput, xInput) * player.moveSpeed / Entity.SQRT_2;
    }
}

PERFECT!

All I had to do was let a Physics2D.Raycast() method in my IsSlopeDetected() method return the RaycastHit2D type (instead of bool ,which is what the tutorial had me do before). I didn't have to change anything I already wrote because it reads implicitly as a bool.
Then I just accessed the normal property.

I still have the rigid body set to isKinematic when in idle state on stairs so it doesn't slip

[gaunt ice]

You can store the hit info in some variable

[livid tundra]

oh you are right

I am calling it again

[queen adder]

Im new to unity, can anybody help me fix these errors?

[livid tundra]

I'll do that

[north kiln]

Don't cross-post

Hi, Im new to Unity and I am creating a basic cookie clicker game for a school project. My cookie counter is set to 0 and words perfectly fine, but when I click the cookie it does not register the clicks, and the counter does not increase either when clicking. Any help? >:D Please

!code
but also what is calling OnCookieClicked

The OnCookieClicked method, in turn, calls another method named IncreaseCookie

public void OnCookieClicked()
{
IncreaseCookie();
}

public void IncreaseCookie()
{
CurrentCookieCount += 1 + CookiesPerClickUpgrade;
UpdateCookiesPerSecondUI();
}

[slender nymph]

that does not answer the question i asked

[queen adder]

sorry english isnt my first language, what is your question?

[slender nymph]

what is calling your OnCookieClicked method

[queen adder]

sorry, what do you mean by calling?

[slender nymph]

wdym? you just answered that OnCookieClicked calls IncreaseCookie. so clearly you know what calling a method is, right? so what calls OnCookieClicked

[queen adder]

I have no idea, I chat gpted

[round scaffold]

[slender nymph]

it is against server rules to ask for help with AI generated code.

[queen adder]

This code isnt ai generated

[slender nymph]

then what calls OnCookieClicked

[queen adder]

I have no idea

[slender nymph]

the answer is probably nothing which would be the root of your issue. but you seriously need to go learn the basics. there are beginner courses pinned in this channel to help you get started

[charred spoke]

A method that calls another method that has two lines one of which is another method call does look like something a gpt will spew out 🤣

[queen adder]

bro I have no idea want im doing I just want the damn cookie to click and number go up so I can get a decent grade for this assignment

[round scaffold]

what if ur teacher finds out its ai code

[queen adder]

bro the code isnt ai

[charred spoke]

Well maybe you should have listened more in class?

[queen adder]

bro we didnt even learn unity in class lock in lil bro

[charred spoke]

Then why is your assignment in Unity ?

[round scaffold]

if u just need a grade just follow a tutorial and get it done in like a day or two

[solemn summit]

Just make the cookie a UI button and slap your OnCookieClicked on there, bingo bango A+

[queen adder]

so ummm guys, how to make the cookie click

[slender nymph]

so did you think i was asking what called OnCookieClicked for shits and giggles? because the answer is obviously that you need to call that somewhere

[queen adder]

ummmm no swearing pls

ok but I still dont understand what you are saying

[slender nymph]

something needs to call OnCookieClicked or else it won't be called

and what happens when OnCookieClicked is not called?

[solemn summit]

Called = Activated. Something, somewhere, in code or a UI button element, ANYTHING, needs to make that code run

Because right now it's just a block of text that isn't doing anything

[queen adder]

THANk you I was waiting for that

[solemn summit]

Until something CALLS it, and tells it to do what it's holding

[queen adder]

does this not call it?

[slender nymph]

again, there are beginner c# courses pinned in this channel

[queen adder]

This is a one time thing, I just need a simple clicker game to be created

I am sorry for this inconvience to you guys though

[slender nymph]

lol sure kid. but you likely won't be getting answers from most of the people who usually help around here if you aren't putting in the effort to learn wtf you are doing

[queen adder]

I created a whole code, with all my effort? Although I may be uneducated im still trying my best

[solemn summit]

Slap a Debug.Log in some functions and see what is getting called and what isn't

[eternal needle]

Sitting around using chatgpt isnt effort, you need to go through the actual beginner steps and learn. If you're unsure how to use Debug.Log, as suggested to use above, then that's what you should be researching

[queen adder]

bro this isnt chatgpt 😢

[timber tide]

look into how to log to the console and log the method you call with the button

from there then you can probably get more help

[queen adder]

I’m using the console and debug log to find what isn’t connecting

How to I move on from there

[timber tide]

First thing you should do is check if the method is being called to confirm it's at least being called

from there I'd start logging your counter each time you add a value to it

[coral locust]

Hey guys, i have a project due soon and i've been trying to figure out why my player keeps falling through the ground

[coral locust]

https://www.youtube.com/watch?v=K1xZ-rycYY8&t=83s

i followed this tutorial

i'm really new to unity btw

[cloud flume]

does your character have a collider and the platform/ground

[slender nymph]

Keep in mind that a rigidbody isn't a collider, you would need both

[coral locust]

only the character has a collider

and a rigidbody

[cloud flume]

you need a collider on the platform

[coral locust]

ok ty

[coral locust]

how do i allign it to perfectly shape the tile

platform

[cloud flume]

the three dots next to edit collider click on it and adjust the collider

[slender nymph]

The platforms are on a tilemap, so you could use a tilemap collider

[coral locust]

if i'm trying to make a one way platform can it still work with a tilemap collider?

[slender nymph]

Probably not

But either way, none of this is code related at this point

[cloud flume]

can anyone help me with this, im trying to make it so the camera can move 360 around the character but it seems to get stuck like it hits a wall at a certain point

i have a video if you need to watch

[slender nymph]

obligatory: use cinemachine

[queen adder]

@slender nymph You doubted me you pussy bitchass I'm the king lil bro dont ever try to not help me again

[native seal]

Can anyone explain why I am getting a Null Reference Exception error here?

[slender nymph]

Have you assigned anything to inventory?

[native seal]

yes

[slender nymph]

Show the full error including the stack trace

[native seal]

NullReferenceException: Object reference not set to an instance of an object
UIInventory.Start () (at Assets/_Scripts/UI/UIInventory.cs:11)

the event still works though

im just getting that error

[slender nymph]

And line 11 is that line in Start?

[native seal]

11 is the assignment

[slender nymph]

Okay then you have another copy of the component in the scene where inventory was not assigned

[gaunt ice]

See if same script on multiple gameobjects

[native seal]

oh shit thanks

feel dumb now

i got a question tho with events, what would the difference between "public Action OnItemUpdated" be vs "public event Action OnItemsUpdated" and what does assigning it to delegate {} do? just ensure its not null?

[slender nymph]

The event keyword makes it impossible to invoke the event from any other type of object. And it is not necessary to assign the empty delegate to it, you could just null check it (which you should be doing anyway)

[native seal]

so ?.Invoke to null check

[slender nymph]

Yes

[native seal]

what do you mean "any other type of object"

[eternal needle]

the event keyword also only exposes add/remove, meaning other scripts cannot just assign your delegate to null (removing all subscribers)

other scripts cannot invoke the event

[native seal]

ah okay

so things with a reference to it cant invoke it

sort of like private

[mystic axle]

hi

can i get some help for something

how do i instantiate a prefab so that it is always five units away from the player, but in the direction that the player is facing

[slender nymph]

get the player's position, add 5 units on your preferred axis and use that Vector3 as the position you pass for Instantiate. then get the direction from that position to the player to use for the direction it faces

this is a code channel

[odd mason]

oh crap my bad

[mystic axle]

wouldnt that only instantiate along whatever axis i choose though

[slender nymph]

yes, if that is not what you want then you need to be specific

[eternal needle]

the direction the player is facing is gonna be transform.forward

[vestal eagle]

Do unity support rust language?

[mystic axle]

ok thanks

[slender nymph]

no. unity uses c# for its scripting language

[vestal eagle]

Nooo

Look like i have to other game engine

[earnest tendon]

hello, so im trying to add multiple characters to my game rn, and ive set 2 buttons, one that would start the game with 1 character and a difretn button that would start the game with a difrent character, how would i make it so when the player clicks a button the sprite of the character and the move animation of the character changes to a difrent sprite and movement animation?

would i have to make a completely new scene with a difrent character prefab?

[slender nymph]

i would make another character prefab as a prefab variant. but you don't need a copy of the scene for that. just have some object that can be used in both scenes like a DDOL object, scriptable object, or static variable that tells your gameplay scene which player prefab to spawn

[fossil drum]

Good luck with that, no big game engine uses Rust as its scripting language.

[vestal eagle]

Spain without s

[earnest tendon]

a DDOL object?

[slender nymph]

DontDestroyOnLoad

[earnest tendon]

ah i see

[misty raft]

Question. How do I make it so when the game starts a amount of objects are disabled

[slender nymph]

put those objects into a list/array. on Start or Awake: optionally shuffle said list/array, get random number from 0 to the collection's length or max disabled objects, iterate through the collection and if the index is smaller than the number generated disable that object

[shrewd swift]

i got a problem
I switched computer, my Unity Project is on a USB key.
I did this a ton of times the past months, no issues.
But now I got a bunch of errors, related to some missing references of assemblies.
when opening the error in VS nothing shows

is Unity bugging or something ?

[teal gulch]

well you could try c++ programming in unreal

[slender nymph]

library is probably corrupted

[shrewd swift]

how can i reload without loosing stuff ?
URP seems to bug also, mat are now pink

[slender nymph]

you can delete the Library folder and restart Unity and VS and it should theoretically start working. but its' best to not copy your project using a USB like that, but use some sort of version control like git or Unity Version Control instead

[vestal eagle]

I try but its lag

[eternal needle]

Sounds like the good old lesson on why you just use verison control

[shrewd swift]

doesnt explain why it happened

[teal viper]

Probably missing/corrupted packages

[shrewd swift]

well rn im removing then re-importing the packages were there is errors, but i dont see how this would solved the issues

[shrewd swift]

im not copying my project, im loading it on both computer from USB.
I could use version control, but connection is slow at work so i would lose time each time to resync

[slender nymph]

well that's probably worse. the issue is likely corrupted files 🤷‍♂️
regenerate your package cache using the instructions i gave you

[eternal needle]

Loading directly from usb would be horrible, you're limited to the speed of the usb. Also for version control you would only have to sync small changes, it wouldnt be the entire project everytime.

[shrewd swift]

im trying, cant copy/move/delete anything from my explorer, weird
im rebooting my pc

[shrewd swift]

after fixing the issue i'll give it a try

[slender nymph]

sounds like a read/write issue then. hope your drive isn't dying

[shrewd swift]

i hope to

[slender nymph]

if it does, you will have learned a very important lesson about always using version control

[mystic axle]

how do i do this for an instantiated object

wait

never mind

all good

sorry

[slender nymph]

Instantiate returns a reference to the object that was instantiated. use that to assign its forward

[shrewd swift]

im getting flashback of an project lost i had in UE two years ago :')

what is VirtualArtifacts/Primary/ ?

[teal viper]

Some compiled binaries I think

[shrewd swift]

ok

well deleting library folders and restarting the project fixed all isssues

very weird that everything got corrupetd
i'll try installing UVC just in case

[teal viper]

Its not like it got "corrupted". You probably copy pasted everything including the library folder. Stuff in it is compiled specifically for the local environment you run the editor in, so it might fail to work properly on a different machine.

[eternal needle]

Consider using git/github. Its pretty easy to use and has some different options for GUIs. It's also commonly used in every other aspect in computer science, so you'll need to know it if you do anything other than game dev.

[mystic axle]

how do i destroy a prefab from a different script

i mean

an instantiated prefab

but not all of the instantiated prefabs

[shrewd swift]

as said above, i did none copy/paste

project is on USB since october, from my MAIN pc and LAPTOP i am loading the project from the USB

so the files are not "changed" from that

maybe i disconnected the usb to soon ? idk, i always make sure unity & VS stoped

[teal viper]

Well it's basically the same, as you keep the same files that were created uniquely for the other environment.

[shrewd swift]

anyway, I now setup UVC in one of my main drive, will do that same back home

[shrewd swift]

you need its ref, then use Destroy(the object here)

[shrewd swift]

github has space limitations
i'll go with UVC for now

[eternal needle]

You really wont run into issues with it. There is git lfs if you really need it, but I doubt you have many assets that are in the GBs.

Either way at least u got some vc

Hi im NEW to coding and i thought i might just start by following a tutorial 1 for 1 and i did, this one https://youtu.be/1uW-GbHrtQc?si=KFbQGVzXYBzisfr6 i have followed it exactly but its not woking when the movement script gets dragged to the player file it only dose (pic 1) insted of what is show in the video at 1:40 . had VS Code set to C++ then changed it to C# and it still doesn’t work.

[slender nymph]

im tryna work on an enemy that patrols between a set of points

but it is just standing there

and wont move

here is the setup in the inspector

[hexed terrace]

are the patrol points actually placed at a different position ?

[restive kernel]

@slender nymph thank you soooo much for ur time and help it worked but idk how i think i didn’t have VS code set up properly

[hasty spire]

yes they are

these are the two points @hexed terrace

[icy sluice]

I can give you my simple movement script

[restive kernel]

I wouldn’t mind

[icy sluice]

Give me 10min until i finish my lunch

[hexed terrace]

When you follow a tutorial, if it is working in the tutorial and not for you .. then you either did something wrong or missed something, go back over it

VSC being "set to" C++ or C# isn't relevant, will make no difference to whether it works or not.

[icy sluice]

My parents always taught me not to take code from strangers.

[woeful hedge]

void OnTriggerEnter2D(Collider2D collider)
    {
        if (collider.gameObject.tag == "Player")
        {
            Debug.Log("Triggered");
            Event.Invoke();
            Audio.Play();
            if (BreakOnActivate)
            {
                Destroy(gameObject, 0f);
            }
        }

    }

so I just added this code to play some sfx

but the Audio wont come out, what should I do?
the debug.log showed well and the audio file is noting wrong

[hexed terrace]

What GameObject is Audio on ?

[woeful hedge]

itself

wait

[hexed terrace]

You're playing it then destroying the gameobject straight away

[woeful hedge]

oh

nah I hate myself

Thanks bro

[hexed terrace]

We've all done it

[hasty spire]

carwash are these logs correct?

[hexed terrace]

You tell me... did you just type them and then take a screen shot? Or did you run the game and test ?

[hasty spire]

i ran the gake

gamw

game

[hexed terrace]

You can edit msgs.

[hasty spire]

i couldnt be bothered

[hexed terrace]

now log out the target pos, not the index

[hasty spire]

how would i do that i get an error that patrolpoints dosent contain a definition for transform

would i use a serialize field?

[hexed terrace]

then that's your problem, there is no target position assigned

[hasty spire]

well shouldnt my array handle that?

i have the transforms of my points in the array

[ruby python]

Have you capitalised the T in transform in your code?

[hasty spire]

yes

[ruby python]

Okay, just checking, you'd be surprised at how many times something like that can be the culprit.

[hasty spire]

it wouldnt be the first time for me, thats why i made sure

[ruby python]

Do you get the Transform error when you try to debug 'patrolPoints[currentPointIndex].position' ?

Also, for future reference, don't screenshot code, it's a pia tbh.

Hey guys I have a question, I have this code and I cannot figure out where I'm getting this error. When I fire up the game if I shoot the medium monster first, things go as intended, but when I hit the hard monster I get thrown a NRE error on this script. If I shoot the hard monster first, it goes just fine, but then try to shoot the medium monster and the NRE gets thrown again.

https://paste.ofcode.org/EnMX5GGZfiVTA6JMQPkMCL

I'm kinda at a loss rn

[hasty spire]

i dont

[ruby python]

Okay, what are you debugging when you get the Transform error?

[hasty spire]

i was making a mistake anyways here is he result

[ruby python]

Try debugging your compareTags. On the surface I can't see any reason for the issue tbh, but could just be tired.

[hasty spire]

https://paste.ofcode.org/gBuETwmrqq4s6EvK5ZfP8Q

this is my code

[ruby python]

Also, I'm not 100% sure on this, but it may be better to deal with the collision/killing the monsters on the actual monsters themselves instead of referencing them through the bullet (if that makes sense?)

[gilded pumice]

I was thinking of this but wasn't sure if the monsters could reference an instantiated object very well. I'll give it a whirl though

[hasty spire]

so do you have any idea what the problem is with it?

[ruby python]

Yeah you should just be able to check if the monster has collided with a bullet and adjust the monsters health accordingly. Pretty much exactly the way you have done already but in reverse, and you would only need one 'Monster script' just with different max health levels.

[ruby python]

I'm not sure tbh. Try wrapping your main If/Else inside the if(once==false) check. Not sure if that's the issue, but worth a try. lol.

if (once == false)
    {
    once = true;    
        StartCoroutine(Wait());
    }
else if (transform.position != patrolPoints[currentPointIndex].position)
    {
        transform.position = Vector2.MoveTowards(transform.position, patrolPoints[currentPointIndex].position, speed*Time.deltaTime);
        }

Maybe that?

[gilded pumice]

after a little more testing I think it has to do with the script looking for either a medium or hard monster script when none exists anymore (because the monster with the script is now destroyed)

[ruby python]

Ah, yeah, sorry, shoulda spotting that tbh. To get around that I would remove the 'find' at the start and just use the collision to grab the script(s)

[buoyant knot]

sounds to me like you need to use more Debug.Assert

[hasty spire]

nope

not working

i think im gonna come back to it after sleep

[ruby python]

Ah sorry. 😦

[gilded pumice]

can you explain how to use the collision to grab the scripts? I'm still new to scripting and I've never retrieved components of other scripts outside of the start/awake methods with constructors

[shrewd swift]

is there a way to make the value not taking to much space ?

[icy sluice]

Kinda

[shrewd swift]

how ?

[icy sluice]

You are using 2 floats here

Right

If you want to change how it looks, you will need to add a custom editor

And if you have just these 2 floats, i personaly dont reccomend

Use a header as a text and just add a singlecharacter as a value

[ruby python]

Trying to remember this off the top of my head, so this may not be 100% correct. But......
Remove your two 'Find' Lines in Awake.

Then in your collision checks add this (change as required)

mediumMonster = collision.gameObject.GetComponent<mediumMonster>();

[icy sluice]

Example

[Header("Global added height...")]
Public float GH = 0f;

[shrewd swift]

that might do the trick, ty

[icy sluice]

Np

Sometimes cheating unity inspector is better than making a whole custom inspector xd

[gilded pumice]

perfect this worked like a charm thank you

[ruby python]

Cool. 🙂 No probs.

[fringe kindle]

How do you switch scenes but keep your original position when you switch back to the original scene?

Because I know that loadscene resets the scene back to it's original state

How do I keep my character's original place in scene A from when I switch to scene B?

[gaunt ice]

https://learn.unity.com/tutorial/implement-data-persistence-between-scenes

general case: from scene A->B->C->....->Z then go back from Z->Y->X.....->A, you need a stack

[frosty hound]

Store the position in a save. Or a better way would be to keep your player/managers in a root scene and load your gameplay scenes asynchronously.

[bright oxide]

Out of incapsulation point of view, can i destroy a gameObject this way?

[brave compass]

This is a question for #↕️┃editor-extensions

[bright oxide]

I was thinking of moving the destroy logics to the item script, but then i would have to use IsFull() method from the Inventory, and i dont know if that is good either

[modest palm]

ah ok mb

[polar acorn]

Since item is a mono behaviour, you should just be able to use .gameObject, I'm not sure .GameObject() exists

[brave compass]

It's completely subjective which is better, but personally, I don't think it should be the item's responsibility to detect pick ups and add itself to inventories. I prefer to think of items as passive things in the world that are waiting to be picked up. I would separate the pick up behavior into its own script that does the OnTriggerEnter, adding to the inventory and destroying. Think of it as the interface between the "real" world and the abstract inventory world.

[polar acorn]

But having the inventory be responsible for destroying the item only when it actually has room for it is perfectly valid, it's what I'd do as well. The item doesn't know if it should destroy itself without knowledge from the inventory, so it shouldn't be responsible for destroying itself

[buoyant knot]

i disagree. I would do it the other way around

i would make Inventory.TryAddItem(Item item);
I’d make it return a bool to let the thing trying to add item to inventory know that it cannot be added.

then item should be responsible for knowing if it should destroy itself, or just ignore and stay on the ground, or whatever

because only the Item knows what to do when it is personally added to inventory. It might need to invoke something when it is successfully added, or it might be in a pool

[polar acorn]

That's actually a much better pattern. This is probably what should be happening.

@bright oxide

[bright oxide]

Thank you very much, that does make sense

[tawdry totem]

basically when im not looking at the weapon im referencing the outline that is false on the code, how i make it doesn't count as an error, the game works just fine with the bug, i just wanna remove the error message

[buoyant knot]

handle the error. don’t ignore it lmao

it IS an error, because you are working with something expected to not be null. It is null, and you don’t have a case for it

make a case for the thing being null, and make a case for it

[eternal needle]

Do yourself a favor and turn on error pause. Also we cant see what line 35 is here.

[swift crag]

You should have zero errors in your console. If you see them, fix them.

[swift crag]

errors caused by thrown exceptions mean that your code is just..randomly getting murdered

which makes it a lot harder to reason about what your code is doing

[swift crag]

You should do this instead:

if (hoveredWeapon.TryGetComponent(out Outline outline))
  outline.enabled = true;

Or, even better: gunScript should reference an Outline component

I would do that if every gun had an outline on it

[buoyant knot]

also GunScript should be capitalized

it is a class name

[tawdry totem]

ok, how would i do so

[buoyant knot]

use the VisualStudio rename feature to have it automatically rename gunScript everywhere it appears in code

I believe it is shift+ctrl+R, when you click on the name you want to change

[buoyant knot]

you wrote GunScript. Just… add a reference to the component to the class

example:
[field: SerializeField] public Outline outline {get; private set; }

example2:
public Outline outline {get; private set; }
private void Awake() {
outline = GetComponent<Outline>();
}

[tawdry totem]

oh, like an singleton

[buoyant knot]

what? this has nothing to do with a singleton

a singleton is a class that enforces that at most 1 instance of it exists at a time, and provides access to that one instance

[tawdry totem]

i mean the way its written

[buoyant knot]

if that is how you wrote a singleton, then it is not a singleton

if you have a monobehaviour singleton, then its Awake needs to check to see if another instance of itself exists already, and if so, destroy what would be the a second instance. If it does not exist, that instance assigns itself as THE instance for the class

does that make sense?

[tawdry totem]

uhum

[buoyant knot]

GunScript just needs to hold a reference to a different object that is publicly accessible, but NOT publicly modifiable

[buoyant knot]

which is why I wrote it like this

[tawdry totem]

btw this needs to be on the update void right?

[buoyant knot]

what? no

this is just in the definition of the class

[tawdry totem]

so i can just do this right?

[buoyant knot]

yes

and also rename gunScript to GunScript using the Rename feature of your IDE

[fringe kindle]

my SceneManager.LoadScene isn't working. I have the names of the scenes correct but when I press E on the hubworld, it won't load the level I want it to

[tawdry totem]

👍

[wintry quarry]

GetKeyDown in OnTriggerEnter is basically never going to happen

unless you are spiderman

[tawdry totem]

and to rename its ctrl + r, its ctrl + r

[buoyant knot]

Input.GetKeyDown is true for exactly one frame

OnTriggerEnter is only even called during fixed update frames

[fringe kindle]

Weird because it worked fine when reloading my Snowboard Game with a button (using LoadScene). I used getkeydown in ontriggerenter and it reset when I hit the key

[wintry quarry]

doubt it

it's wrong for two reasons

[fringe kindle]

Wait scratch that

[wintry quarry]

1. OnTriggerEnter is similar to FixedUpdate in that it runs in cadence with the physics update, which doesn't run every frame. It's very likely your key press will land on either side of a physics frame

[fringe kindle]

I forgot I changed that code

[wintry quarry]

2. The timing required is basically impossible

[fringe kindle]

Forget what I said about it working

[wintry quarry]

yep

[fringe kindle]

So what could I do instead?

[buoyant knot]

GetKey is true on any frame where the key is down

[wintry quarry]

Depends what behavior you're looking for

you want to be able to press a button while inside the trigger?

[fringe kindle]

Yes

[wintry quarry]

Then keep track of when you're inside

with a bool

set it true in OnTriggerEnter, false in OnTriggerExit

then in Update you can listen for the input and check if you're inside as well

if (Input.GetKeyDown(...) && currentlyInsideTheThing) {
  // do something
}```

[buoyant knot]

you’d do the same thing with InputSystem, but it would instead invoke just the function of what to do when pressing down

instead of checking in update

[keen hill]

yo i need help with referencing the rigidbody of another object and on collision doing something can someone can help me possibly through a vc??

[wintry quarry]

no VC in this server. Ask your question here

[keen hill]

i just asked

[wintry quarry]

You need to provide details of your problem to get an answer. #854851968446365696

Explain what you tried and how it went wrong

[merry spade]

Im currently making a Board of buttons and allready have the script to activate them, but now I am thinking of the best way to implement functionality, do I have to implement a new script for every button or how can I call different functions with one script?

[wintry quarry]

Buttons have an onClick event in the inspector which you can assign to any function you want.

[buoyant knot]

Button components can be set to call a specific method of a given component in the scene

[keen hill]

okay so im writing a script about picking up an item and then on collision playing a sound but i dont know how to reference a different gameobject's rigidbody and using the fucktion on collisionenter i can provide a script

[wintry quarry]

OnCollisionEnter provides a Collision parameter which contains a reference to the other object

It also has this which directly gives you the other object's Rigidbody https://docs.unity3d.com/ScriptReference/Collision-rigidbody.html

[lunar grove]

Anyone know on how to instantiate a Script instance attached to the same GameObject within a Script?

[keen hill]

i want it to react to my picked object collision

[buoyant knot]

i believe the collider has better direct access to the rigidbody, if I’m not mistaken

[keen hill]

so when my held object touches something it makes a sound

the problem is i have the pick up script on my player

[wintry quarry]

What do you mean by " instantiate a Script instance attached to the same GameObject"?

[buoyant knot]

GameObject.AddComponent

[merry spade]

No they are 3D buttons in the game not in the overlay

[keen hill]

and i want to reference the object rigidbody which i did but i dont know how to like "connect it" to on collision enter

[buoyant knot]

as in:
CircleCollider2D myCollider = gameObject.AddComponent<CircleCollider2D>();

[keen hill]

sorry if im wrong im a beggienr

[wintry quarry]

Use a UnityEvent

[wintry quarry]

You don't need to reference anything in the inspector

#💻┃code-beginner message The link i shared has an example

follow it

[merry spade]

how?

[icy sluice]

what does he need?

[merry spade]

can you link the documentation?

[wintry quarry]

https://forum.unity.com/threads/unityevent-where-have-you-been-all-my-life.321103/

[merry spade]

ty

[keen hill]

oh i think i get it now

Thanks brb ill let you know if it works

[lunar grove]

I have a script attached to a game object, now I have another script attached to that same game object and I want the other script to instantiate that same script in its code

[icy sluice]

to run a function from another code, you must, check if function is public

[buoyant knot]

that still doesn’t make sense

[lunar grove]

Oh wait is this the code for what I'm trying to do

[swift crag]

what are you actually trying to make your game do?

[lunar grove]

gameObject.GetComponent<SpriteAnimationScript>();

[buoyant knot]

still not clear

[wintry quarry]

What does "instantiate that same script" mean? What is the end result you're looking for?

[wintry quarry]

this doesn't instantiate anything, it gets a reference to an existing thing.

[icy sluice]

ok, now you got the script that its atached to, but dont remember to do it like this
SpriteAnimationScript SpriteanimationYourNamwwhatever = gameObject.GetComponent<SpriteAnimationScript>();

[lunar grove]

Exactly, sorry for the wording

[wintry quarry]

so what's the question?

Sounds like you already know the answer

[lunar grove]

I was trying to get a reference to an existing script attached to my gameobject for another script that is also attached to it to use

[icy sluice]

now that you have SpriteanimationYourNamwwhatever
you can do SpriteanimationYourNamwwhatever.{name of the function}(some args)

[wintry quarry]

You answered your own question here #💻┃code-beginner message

this is correct

(except you don't need the gameObject part, it's extraneous)

[icy sluice]

oh, yeah

[lunar grove]

I don't?

[icy sluice]

no, you dont

it already knows you want to pull from object its already on

[lunar grove]

Alright thanks

[icy sluice]

like it would do any difference

[swift crag]

GetComponent is a method on both GameObject and Component.

It looks for a component on the game object or the component's game object

[buoyant knot]

in a MonoBehaviour, GetComponent() calls gameObject.GetComponent()

[lunar grove]

Ahh okay okay I see I see thanks for the help!

Do i use a descriptive name for the Down Arrow Key when using GetInput?

[wintry quarry]

wdym by "GetInput"?

If you are using GetKey you should use https://docs.unity3d.com/ScriptReference/KeyCode.DownArrow.html

[lunar grove]

I mean GetButton

lol

[swift crag]

GetButton doesn't care about specific keys on your keyboard

It uses buttons that are defined in the Input Manager

like "Fire"

[wintry quarry]

GetButton corresponds to the axes in your Input Manager settings

[lunar grove]

But it has a setting

Negative and Non-Negative Names

[rocky canyon]

GetButtons are presets..(automatic) GetKey would be a specific key.. (manual)

[swift crag]

oh, those are names you can use to describe the axis

[rocky canyon]

axis.. like up and down arrow ^

[lunar grove]

ah

lol

[swift crag]

I've never touched that before

They aren't functional.

[keen crescent]

Having a weird issue: I'm using a script that uses a Level ScriptableObject to instantiate prefab lights etc. for a given level
This works perfectly, but I'm trying to do the exact same thing with a particle system prefab, and I'm getting "The Object you want to instantiate is null." when it is definitely not null. Its field is populated in the ScriptableObject and the there's nothing wrong with the asset itself (in fact, its an exact copy of an asset I'm already instantiating somewhere else, I just copied it to test)
Any ideas?

[swift crag]

I guess you could put in "Up" and "Down" in the positive and negative name fields

or "Throttle" and "Brake"

[lunar grove]

Ah i see isee thanks

[swift crag]

are you referencing the correct scriptable object asset?

[polar acorn]

Work the problem in reverse, checking every assumption along the way. Start with the error, what line is it on?

[keen crescent]

Yes, but even if I wasn't, why would it be null?

[keen crescent]

private void AddParticles(Level currentLevel)
{
Object.Instantiate(currentLevel.LevelParticlePrefab); < error here
}

[swift crag]

because you might have an asset that doesn't have a particle system prefab assigned

or your code is doing something else that's causing the error

[swift crag]

okay, so this will only throw that specific exception if LevelParticlePrefab is null

now verify that currentLevel is what you think it is

if you do this, you can click on the log entry to be taken to the asset

Debug.Log("I'm at: " + currentLevel, currentLevel);

[keen crescent]

It's definitely assigned in the inspector, and all else equal, the code runs fine, with the script accessing the correct Level SO

[polar acorn]

Okay, what is currentLevel?

[swift crag]

well, it's throwing an exception, so something sure isn't equal

[tawdry totem]

even after the fixes it still shows the error

[polar acorn]

What error

[keen crescent]

A given Level object with its properties read from a Level ScriptableObject
All other values are being read from the SO correctly, it only gives an error during this final step
Commenting that one line out, everything works as expected

[swift crag]

That doesn't answer digi's question

[swift crag]

consider checking what currentLevel is actually referring to

prove that it's the correct asset

It doesn't matter what you think your program is doing

[tawdry totem]

here

[swift crag]

if your weapon has no outline component, then outline will be null, and you'll get an error

[tawdry totem]

with the fix

also there is a reference on GunScript

[swift crag]

note that this isn't using the GunScript.outline field at all..

It sounds to me like hoveredWeapon doesn't have an Outline on it.

[wintry quarry]

line 35 establishes already that the object does NOT have an outline component. So line 39 will always give you a NullReferenceException

[swift crag]

oh, good catch

that else block is in the completely wrong place

[wintry quarry]

What you need to do is save the Outline reference for later

in a member variable

[swift crag]

it sounds to me like it should be after the if (Physics.Raycast... bit

[keen crescent]

I'm 100% certain that its accessing the correct Level and Level SO, I already tested for that

[swift crag]

and line 32 shouldn'tbe looking at hoveredWeapon. surely it should be looking at the thing you just hit

[swift crag]

So did you do what I suggested?

[keen crescent]

Yes, but like I said, I already tested that

[swift crag]

So you logged currentLevel before you tried to instantiate its particle system prefab, and when you clicked on the log entry, it took you to the correct asset in the Project window?

[keen crescent]

the currentLevel value isn't itself an asset, but the SO is

[wintry quarry]

I'd do this @tawdry totem

Outline lastOutline;

void Update() {
    if (lastOutline != null) {
       lastOutline.enabled = false;
       lastOutline = null;
    }

    // other stuff
    if (Physics.Raycast(...)) {
      if (hit.transform.TryGetComponent(out Outline newOutline)) {
          lastOutline = newOutline;
          newOutline.enabled = true;
      }
    }
}```

[keen hill]

It works perfectly thanks !

[swift crag]

So you're instantiating a Level asset at some point?

Or do you just mean you're passing a reference to a scriptable object asset into that method's currentLevel argument?

[swift crag]

[SerializeField] Level myLevel;

void Foo() {
  Bar(myLevel);
}

void Bar(Level theLevel) {
  // ...
}

[keen crescent]

The LevelSO is the asset, so currentLevel is just an object in code that gets the values from that asset and uses them

[tawdry totem]

replace all in the update method?

[swift crag]

Show me your entire script. I need to see what you're doing.

[keen crescent]

Nevermind, I got it

[polar acorn]

If I had a nickel for every time someone said they were 100% sure of something that turned out to not be the case I'd have enough nickels to put in a sock and smack them until they checked it to make sure

[keen crescent]

Okay but I was right tho

[polar acorn]

You still need to check everything

[keen crescent]

I literally said I did already

[swift crag]

You're not instilling confidence by ignoring what I'm asking you to do and saying you're "100% sure"

[keen crescent]

Thanks for the help though, I know what I did wrong, I had to fix a line in the Level constructor

[polar acorn]

I have seen no message from you confirming what currentLevel is other than you saying you were "100% sure" that everything was correct, in which case you wouldn't have an error

[swift crag]

Level has a constructor?!?

[keen crescent]

sorry, not the actual constructor

[cosmic quail]

if theres a bug then u cant be 100% sure that everything is correct

[swift crag]

ah, okay.

[cosmic quail]

you can be 100% sure that something is incorrect tho

[swift crag]

(because ScriptableObject types should not be constructed directly)

[keen crescent]

it's not a ScriptableObject

[polar acorn]

Once we confirm the level is correct then we move on to seeing if the referenced prefab is correct and so on

[swift crag]

so there's a different Level type that is a scriptable object

[keen crescent]

Correct

[swift crag]

that would have been very useful information to have.

[polar acorn]

That's what debugging is, building a core of confirmed truths until you find the one that is different than your assumptions

[swift crag]

and I presume you just weren't copying the particle system prefab reference over, then

[swift crag]

also, this would have been a compile error if currentLevel was not a unity object

which suggests that you didn't try it...

[buoyant knot]

and dropping a ton of assertions to try to trip up the first part of the chain that does not match assumptions

[keen crescent]

I noticed that but I tried debugging values from the currentLevel, which did confirm it was reading correctly

idk why ya'll are assuming I just said I was 100% certain it was reading correctly without testing anything

I don't ask questions without trying to debug I promise!

[polar acorn]

Because we cannot see your screen so when we ask for information you have to actually provide it to us

and, again, dozens of people a day come in here "100% sure" of things that are just patently untrue

[swift crag]

(they also have generally already 'tried everything' and 'tried thousands of times')

[polar acorn]

(and "did it exactly like the tutorial")

[keen crescent]

Yeah understandable

thank you guys

[swift crag]

I was under the false impression that Level was the level scriptable object

[buoyant knot]

all he said is that the instances being accessed are the correct instances

[swift crag]

that was the hangup

(which is why sharing code helps, too)

i'd have cottoned on pretty quickly then!

[keen crescent]

Yeah I would have shared more but it's a bit cumbersome and split between a few scripts, sorry

[lucid path]

these are in separate scripts, the latter of which is an instantiation. i’d like to avoid using a public bool across the two scripts if that is possible

[twin bolt]

Why am i unable to move if the player is looking completely down? ``` float horizontalInput = Input.GetAxis("Horizontal");
float verticalInput = Input.GetAxis("Vertical");

        Vector3 forward = playerCamera.transform.forward;
        Vector3 right = playerCamera.transform.right;
        forward.y = 0f;
        right.y = 0f;  
        forward.Normalize();
        right.Normalize();

        Vector3 desiredMoveDirection = forward * verticalInput + right * horizontalInput;

        rb.velocity = new Vector3(desiredMoveDirection.x * playerSpeed, rb.velocity.y, desiredMoveDirection.z * playerSpeed);```

[wintry quarry]

because playerCamera.transform.forward is straight down and therefore x and z will be 0. only y will have a value

[lucid path]

references with instantiated game objects are incredibly inconvenient

[wintry quarry]

instead of using the camera direction you should use the player body's orientation

[twin bolt]

I used to use that, but realized that rotating the player's body would cause camera jitter.

[wintry quarry]

not if you do it correctly

i.e. rotate the Rigidbody and not the Transform

[twin bolt]

is it the same as rotating with transform or no?

[wintry quarry]

If it was, I wouldn't be suggesting it an implying it's the correct thing to do instead of rotating via the Transform

[twin bolt]

No, i mean code wise.

[wintry quarry]

not exactly

more like:

rb.rotation *= Quaternion.Euler(0, mouseXInput, 0);```

[queen adder]

is it not possible to use if statements in interfaces?

[polar acorn]

keyScript is null

[summer stump]

You are not using an if statement in an interface here. It's in an object that implements an interface.

But yeah, what digi said

[queen adder]

I see your right. Having a hard time understanding why. did I not reference the keyScript correctly?

[polar acorn]

Either there exists an object tagged Player that has no KeyScript on it, or the code you sent in the previous screenshot happens before Start

[rocky canyon]

debug the variable after u assign it and see

[polar acorn]

^ Yes this would check both cases

[rocky canyon]

if it returns null its not..

[queen adder]

I see now. The KeyScript wasn't even attached to the player.

[rocky canyon]

lol, that'll do it

[lunar grove]

transform.position += new Vector3(0, -0.2f, 0);

this changes my object position to -0.2 Y right?

[polar acorn]

by 0.2

[lunar grove]

not negative?

[polar acorn]

Sorry, -0.2

[lunar grove]

it doesnt change on mine for some reason

I coded it to change for every frame that I hold the down arrow key down

[polar acorn]

show code

[lunar grove]

 private void Update()
    {
        characterDirection += Vector3.down * characterGravity * Time.deltaTime ;

        if(characterController.isGrounded) 
        {
            characterDirection = Vector3.down;

            if(Input.GetButton("Jump") && !Input.GetKey(KeyCode.DownArrow))
            {
                characterDirection = Vector3.up * characterJumpForce;
            }

            if (Input.GetKey(KeyCode.DownArrow))
            {
                dinoAnimation.CancelInvoke();
                dinoAnimation.AltAnimate();
                transform.position += new Vector3(0, -0.2f, 0);
            }

            if (Input.GetKeyUp(KeyCode.DownArrow))
            {         
                dinoAnimation.Animate();
                characterDirection = Vector3.down;
            }
        } 
        else
        {
            if(Input.GetKey(KeyCode.DownArrow))
            {
                characterDirection = Vector3.down * characterDownForce;
            }
        }

        characterController.Move(characterDirection * Time.deltaTime);
    }

I just provided the entire update method lol

[polar acorn]

https://unity.huh.how/character-controller/teleportation

[lunar grove]

Ah I see thanks

but wait

oh wait

nvm

[keen dew]

Why don't you just apply it to characterDirection

[lunar grove]

wdym?

[polar acorn]

That's your velocity that you apply to the character controller

if you just add the value to characterDirection it'll get applied to the character controller

instead of trying to teleport the object

[rocky canyon]

manipulate this variable all you need prior to the Move function

add to it, subtract from it, w/e u need.. keeps it clean and easy

[lunar grove]

Ah but i actually need to just reposition my character to look like its still on the ground

[keen dew]

This is the wrong way to do it altogether

[lunar grove]

i just need it to look like it stays on ground after pressing down key

[keen dew]

I understand what the goal is, but how you're trying to do it won't work

[twin bolt]

WHy does the y keep resetting back to 0? ``` yaw = rb.rotation.y + Input.GetAxis("Mouse X") * mouseSensitivity;

            if (!invertCamera)
            {
                pitch -= mouseSensitivity * Input.GetAxis("Mouse Y");
            }
            else
            {
                // Inverted Y
                pitch += mouseSensitivity * Input.GetAxis("Mouse Y");
            }

            // Clamp pitch between lookAngle
            pitch = Mathf.Clamp(pitch, -maxLookAngle, maxLookAngle);

            rb.rotation = Quaternion.Euler(0, yaw, 0);
            playerCamera.transform.localRotation = Quaternion.Euler(pitch, 0, 0);```

[lunar grove]

Is it because of the character controller?

[keen dew]

no

[wintry quarry]

this is wrong why are you doing it yaw = rb.rotation.y + Input.GetAxis("Mouse X") * mouseSensitivity;
