[round plover]

it was the only option

[rich adder]

so if thats the correct one , which one do you think you should change to make it work?

[round plover]

the script

[rich adder]

right

[round plover]

but how

[rich adder]

https://learn.unity.com/tutorial/working-with-textmesh-pro#5f86410eedbc2a00249a4927

[round plover]

should i maybe replace "text" with the text meshpro iu thing

[rich adder]

just look what I sent you for 2 seconds

the solution is there

[round plover]

kk

tyhx

thx

[round plover]

yorursolution was creating a font wich i dotn care about my problem is that i want to drag my textUI into a script i wrote wich tells me the position of my player when it moves foward and i want to drag it into scoretext but it wont let me sorry for the confusion

not good at explaining things

[rich adder]

what in the hell..

how did you even remotely get that from what i sent you..

you're like making stuff up i swear

[round plover]

what.

thats what your solution wasÉ

creating a font asset

[rich adder]

did you scroll up to the code?

the direct link doesn't work well on the learn site its kinda shite

scroll up to the code part

[steep rose]

this seems interesting

[rich adder]

I have no idea why it linked that

[round plover]

bruh aint no way

how do i delete my current one

i made

ill copy what u sent me

nvm

[rich adder]

mate just change the type from Text to TMP_Pro

nothing else

you're overcomplicating it

at some point you do have to know what a TYPE and what a FIELD is so when i suggest something w /them you know what to do..

[somber herald]

I don't understand when to use time.deltaTime and when to use time.fixedDeltaTime. Currently, I'm writing a jump script using velocity and custom gravity, does the gravity force downward need to be multiplied by time.fixedDeltaTime and be in fixedUpdate? Also what about the jump force up?

[rich adder]

custom gravity with what?

[devout flower]

i'm 95% sure that gravity is in fixed updated, and jump is in a regular function without time.deltatime

[somber herald]

with velocity

[rich adder]

what

[steep rose]

fixedupdate is for physics objects

[round plover]

@rich adder am i removing these

[steep rose]

hes using a character controller

prob

[rich adder]

why?

[steep rose]

correct?

[somber herald]

ermm im using a rigidbody

[round plover]

k i keep

[steep rose]

okay

thats

okay

[somber herald]

is character controller better?

[round plover]

yeah nevermind it wouldnt make sense to remove it

[rich adder]

Time.deltaTime in fixed update just becomes Time.fixedDeltaTime

you dont want to use it on velocity no

MovePosition , yes

AddForce, no

[somber herald]

ooh can I ask why?

[rich adder]

its already waiting for the Physics frame to move velocity

[somber herald]

OHH okay

[rich adder]

which is fixed time

[somber herald]

Position isnt physics based which is why you use time.deltaTime instead?

[rich adder]

youll just end up slowing forces applied them by A lot

[rich adder]

no time.deltaTime is used to keep things consistent through different frame rates

its the time between last frame and this frame

[steep rose]

mainly so its not frame dependant

so you dont get extreme speeds at higher frame rate

slow at low

ect

[somber herald]

so when would I use time.fixedDeltaTIme for example?

[rich adder]

yes so take a timer for example without deltaTime ppl with faster fps would drain timer faster in update

[rich adder]

If you need to apply some value over fixed time

consistency

[steep rose]

legit

[rich adder]

from the horses mouth

https://docs.unity3d.com/ScriptReference/Time-fixedDeltaTime.html

and https://docs.unity3d.com/Manual/TimeFrameManagement.html

[steep rose]

i actually have never used fixedtimedeltatime i have zero clue why 😅

[somber herald]

Im kindaaa confused still I know that fixedDeltaTime happens over some like 60 frames and is slower but when would you use it and is it just more reliable than time.deltaTime?

[rich adder]

when you need it to go with the physics step

instead between frames

they're both consistent

but different

[round plover]

@rich adder what in the hell

that is not the position of my player!!!1😭

[steep rose]

what did you even do

[rich adder]

what am I looking at

[steep rose]

to do that

[round plover]

exactly whathe told me to do

[steep rose]

the what

oh

he

he led you in a correct direction

ngl

[round plover]

all i wanted is for that textbox to show the position of my player and now its a mess

[rich adder]

what does that have to do with changing the type from Text to TextMeshPro

you did some other shite I have no clue about, its like you assume i have telepathy lol

[fickle plume]

Practical application of fixedDeltaTime could be inside a coroutine for example, which awaits physics frame and you need to get exact time of the last physics frame.

[steep rose]

😅

[steep rose]

so you

followed the tutorial?

[rich adder]

tell me what does have to do with "Showing Player Position"

cause you're making no sense

[round plover]

nthg

[steep rose]

that wont give you the player position

[round plover]

u just told me to do that

[fickle plume]

@round plover Create threads when posting images. Your posts are completely disjointed

[rich adder]

show me where ?

[round plover]

alright sir

[fickle plume]

You can reuse your old thread for this

[round plover]

its what the code showed

[fickle plume]

just link it here

[steep rose]

yeah but that wont give you the player position

[rich adder]

you're going to have to learn how to separate EXAMPLES of usecase, from copying verbatim...

all you had to do was change the type lol

man I dont got time for this

goodluck

[round plover]

whatever ill figure it out

[steep rose]

ok then

[queen adder]

StatManager.instance.baseHealth -= StatManager.instance.enemyDamage;

is this baseheath-enemy damge or am i dumb bcs it keeps saying its nullrefrenceexeption

[rich adder]

why not make this a method?

[trail gull]

Whats the difference between AssetBundle.LoadFromMemory_Internal vs AssetBundle.LoadFromMemory?

[wintry quarry]

NRE here means StatManager.instance is null

[rich adder]

make sure instance is assigned before you access it

imo you should also make itStatManager.instance.SubtractHealth(enemyDamage)
slight improvement instead accessing the instance twice like that

[queen adder]

oh i thought it meant baseHealth was NRE

[queen adder]

instance = this on the StatManager script

[rich adder]

in start or awake?

[wintry quarry]

A variable is not NRE. A variable can be null. But not if it's just an int or a float

[wintry quarry]

Either you didn't put one in the scene or this other code is simply running before that

[steep rose]

huh thats weird, theres no documentation for AssetBundle.LoadFromMemory_Internal unless im blind

im probably blind

[queen adder]

So it has to mean that StatManager is = null not the var

[rich adder]

StatManager is just a class

instance is null

at least at the time you access it

[queen adder]

in awake I put instance = this

[rich adder]

where are you running StatManager.instance.baseHealth -= StatManager.instance.enemyDamage

[steep rose]

take a look through this
https://docs.unity3d.com/ScriptReference/30_search.html?q=assetbundle.loadfrommemory

this might be what you need

[queen adder]

its red can you see it

[rich adder]

pardon?

[queen adder]

I typed the code in chat its red

[trail gull]

oh well im running it in a method

[steep rose]

i have zero clue why internal isnt on there but idk 🤷‍♂️

[trail gull]

So how am I meant to determine the difference ?

[zenith cypress]

Generally if something has internal in the name, it's meant to not be visible to the user.

[rich adder]

yeah no shit..

[steep rose]

this

[queen adder]

///
public void takeDamage()
{
    StatManager.instance.baseHealth -= StatManager.instance.enemyDamage    
}

[rich adder]

this doesn't help

no context to when and how

[raw token]

Maybe share the whole script via like gdl.space?

[queen adder]

yea ill do that one sec

https://gdl.space/ujavukerom.cs

[rich adder]

static hell lol

which object has StatManager

[queen adder]

an empty object called statManager

[rich adder]

is it in the same scene as this?

[queen adder]

yes it is

[summer stump]

Why are any of those static!? 😭

[trail gull]

What could cause assetBundle to be null here tempStream is 100% not null, what else could it be?

[queen adder]

i thought thats how you reference other scripts to get the variable

[zenith cypress]

Loaded AssetBundle object or null if failed.

[summer stump]

Nope. That is a beginner trap. A really really bad way to do that.

Absolutely ZERO of those make sense as static

https://unity.huh.how/references

[rich adder]

omg no

[trail gull]

Do you know why it might fail?

[zenith cypress]

No I do not use them, just going off the docs

[trail gull]

Great!

[queen adder]

uh oh

[zenith cypress]

Where are you getting the bytes from? Show full function?

[queen adder]

is GetComponent then the script better

[summer stump]

It is ok

A serialized reference is preferred

[queen adder]

What would be #1 method

okay

[rich adder]

[SerializeField]

[rich adder]

where DI tho 😛

that should be SS

actualy thats on par with S, you need S anyway

[summer stump]

The creator has a negative opinion on DI in game dev. Which I kinda get

[zenith cypress]

I still need to play with DI with Unity lol. It never felt good in unity for some reason

[queen adder]

so how would I fix my problem ive been at this for hours

[summer stump]

I have only had negative experiences with it

[raw token]

I've often heard the argument that dragging things to the inspector is more or less DI Lite

[rich adder]

even just this simple one
https://unity.huh.how/references/simple-dependency-injection

doesn't have to be the DI like usual .net injection

that would be awkward

[summer stump]

Yeah, my main experience is zenject

Which was......

[summer stump]

Can you link to the original issue?

[fickle plume]

I think most common criticism about DI is creating overly complicated frameworks for it. There's nothing wrong with just initializing references on instantiation by simply passing them at that time through DI method.

[queen adder]

https://gdl.space/ujavukerom.cs line 48NRE

[rich adder]

Debug.Log the instance before you use it

[opaque aurora]

I need help in importing the Hierarchy from the collaboration
can some one tell me how to do it ?

[summer stump]

Show StatManager

[summer stump]

What is "the collaboration"
And the hierarchy is part of the scene. Be sure you opened the right one

[queen adder]

https://gdl.space/guxixuwise.cpp

[rich adder]

Yeah thats usually trying to do what normal applications with single entry points would be suited for an easy DI, eg asp.net and alike with Program.cs

[summer stump]

Does StatManager actually exist in the scene? (On an object that exists before runtime)

[opaque aurora]

i mean we work together in the same project the files is with him but the hierarchy is not like the one with me it's empty

[summer stump]

I'll tell hariedo to get on it

[zenith cypress]

I guess DI gets a little funky once you start doing instantiations, or things that are outside of the "root" structure for the game. Can't word that properly atm since it's super late haha, but things like that.

[summer stump]

How are you sharing the project?

[queen adder]

yes it does

[opaque aurora]

with unity cloud

[rich adder]

yeah this one is perfect for unity, its very good to prepare objects between scenes without really needing many singletons

[summer stump]

Remove the StatManager variable from basedeath

[rich adder]

Unity Cloud is an array of services..

[summer stump]

You mean Unity Version Control which is connected to Unity Cloud?

[opaque aurora]

yes

[summer stump]

Then make sure they commit their changes, and you pull them

[opaque aurora]

i am new trying to learn

[queen adder]

did that did not fix it

[summer stump]

Have you done the unity guide on Unity Version Control?

[summer stump]

Did you change the reference on line 48 after?

[queen adder]

Its still statmanager

[summer stump]

Oh wait, sorry. It was already going through the type

Gotta debug it like Nav said a while ago. Use some logs to see what is going on

[opaque aurora]

yes but still not helpful

i fix it some way

[queen adder]

Okay i gotta make everything have a value right because im pretty sure I did that

[summer stump]

You need to make sure instance is not null

[rich adder]

so what did you do? cause you're not very clear on whats wrong

[queen adder]

how do i do that

[opaque aurora]

Do have some in YouTube making every thing clear in term of Genral info

[queen adder]

that is prob my problem becuase i have 4 NREs

[summer stump]

With logs, like we said

[summer stump]

Oh... well what is the FIRST nre?

[rich adder]

can you screenshot them

[queen adder]

yep

[summer stump]

It would have been good to know there were 4

[opaque aurora]

this objects wasn't there with my friend

[summer stump]

Did you commit the changes and they pulled them?

[opaque aurora]

no he opened the project different way

[summer stump]

Have you changed the scripts since you sent them? Line 9 of the version you sent before is an int initializer

[rich adder]

did you actually commit them. and did they pull them .

[summer stump]

Then how could he have what you did....
Of course it won't show

[opaque aurora]

i don't know

[queen adder]

they are on multiple scripts 3 total

i have not changed them

[summer stump]

Then you did not save

[queen adder]

let me resend them

[summer stump]

https://gdl.space/guxixuwise.cpp

Line 9 here cannot be null

[steep rose]

so you probably didnt then?

[queen adder]

https://gdl.space/odicudifet.cpp
this is stat manager

[summer stump]

Ohhhhhh

You cut off part of the scripts.....

Include EVERY SINGLE LINE

Good, this one looks complete

[rich adder]

yeah you can't access it in the intializer like that

you're assigning it in awake

[summer stump]

Yes, get rid of line 9 entirely

[rich adder]

aint no way

thats why error is coming from constructor method of MB

[summer stump]

If you have a singleton with the value, just access that.

[queen adder]

what is a singleton

[rich adder]

https://unity.huh.how/references/singletons

[ivory bobcat]

What you've got with that Instance stuff

[rich adder]

singleton aka Only 1

[queen adder]

so it lets me access the variable a singleton

[queen adder]

Is a singelton?

[summer stump]

Every object that you wrote instance in is supposed to he a singleton

You should ONLY have one of each of those scripts in existence at any one point

[rich adder]

before you know what a singleton is you prob should know how an instance work first lol

[queen adder]

I do not know how either work

[rich adder]

im aware lol

[queen adder]

So only one instance ever

[rich adder]

is the best tool around you teach yourself things you're not sure about

[queen adder]

Yea lol i bet its obvious

[rich adder]

or ask for clarification + googling

[queen adder]

okay so I should be using singletons not what ever i was doing

[rich adder]

yea, thats why im suggesting it in a way to learn them a bit deeper

its always good to know what the tools you use do while using them

[summer stump]

What you are doing IS a singleton, as multiple people have said

[queen adder]

wait what

[summer stump]

Not ever. You could have multiple across the runtime, but only one at a time, yes

[summer stump]

If you have a static field that is the type, and you set this to that variable, you potentially made a singleton.

[queen adder]

Okay so only 1 singleton of one script at once

[summer stump]

Yes

[queen adder]

I need to learn what a static field and singleton are

I thought it was just referencing the other script so i could use the variable

[rich adder]

Singleton just means there should only be 1 of this thing

[summer stump]

public static Type Instance

^ static field

[rich adder]

static keyword already makes something the only 1 thing usually.

[summer stump]

Singleton is literally in the name. Single. You have a single one

It doesn't actually even need a static accessor field, but that is useful

[rich adder]

in unity you need to destoy another instance if somehow you have 2 of this script in the scene

[queen adder]

but why what does it do

[summer stump]

Having a single thing you can reference for data is powerful

[rich adder]

Singleton is just a pattern

https://en.wikipedia.org/wiki/Singleton_pattern

[queen adder]

like the stat manger thing?

[summer stump]

If you only have one, it IS a singleton, yes

[queen adder]

So what does that mean

[summer stump]

He just linked info....

[rich adder]

literally..

explains it..

[queen adder]

Okay so what i got isnt a singleton

[rich adder]

you've been told many times you have a singleton there with instance

[summer stump]

If not, then get rid of the instance variable
Because that is a significant issue if you have more than one

It WILL NOT WORK if there are multiple

Static means there is only one in existence basically. So the last StatManager's awake that runs will be the one referenced by Instance

[queen adder]

Okay so i should only ever have one of these public static BasePlayerPrefs Instance;

[rich adder]

https://unity.huh.how/references/singletons#implementation
see how its written here. Imagine this is StatsManager

[rich adder]

this should only be a field in BasePlayerPrefs

[summer stump]

You should ONLY have that inside BasePlayerPrefs and NO WHERE else ever

And only if you are going to only have one BasePlayerPrefs

[rich adder]

otherwise it makes no sense to put it in another class

[queen adder]

Okay i did that wrong I had it in multiple

So once i have it in there im able to reference it correct?

[summer stump]

Yes

BasePlayerPrefs.Instance will lead to that variable

It will statically access the class

[rich adder]

use this in very specific times , dont start making everything static Instance in each class

[summer stump]

For example, you should not have a static accessor to your StatManager, since you have multiple

[queen adder]

It will lead to every varible in that class

[summer stump]

It will lead to the class itself.

Every variable and method

[queen adder]

Okay thats exactly what I need

[rich adder]

instance is the one running and calling those methods

so you only want 1

Classes are just blueprints they don't do anything else

[summer stump]

It will lead to only one instance of the class, and never any other.
Just to be clear

[queen adder]

that makes so much sense

[grave furnace]

hi guys, can anyone help me with my top down movement script? How do i make my player stop when i release the walking button instead of keep walking a bit after i release it?

[rich adder]

when you do = this
this referes to the current Script on this object

[summer stump]

GetAxisRaw instead of GetAxis

Also fix that syntax error where you set velocity

[zenith cypress]

Those are some pleasant editor colors

[queen adder]

exactly becuase I need to get the variables to use on other scripts so when I go into the other script i do StatManger.instance.baseHealth right?

[summer stump]

No, as I said, StatManager SHOULD NOT BE A SINGLETON

[grave furnace]

are you talking to me?

[summer stump]

Is there only one BaseHealth that everything will have?

[rich adder]

well yeah in other scripts this accesses those fields

[summer stump]

Or do you want different things to have different baseHealths

[grave furnace]

thats Lunar Pink Theme

[queen adder]

Only the "base" is gonna have that variable I have enemy helath as well

[rich adder]

@zenith cypress got the best emojis

[summer stump]

You should definitely not make this a singleton

Definitely not have a static variable

Just make their own with their own values

I mean, you could do that, but it seems so muddy to have a ton of health variables for all these different things.
Hard to extend, and gets to be a massive mess real quick

[queen adder]

I have base and enemy health i will add more enemies though

[summer stump]

Exactly

[queen adder]

So i should not make it a singleton

I need differnet variables for each type of helath

[summer stump]

I mean, some of it could be. You have the coin multiplier, that makes sense.

But I would do a script for each prefab type that has its own health values

Like an enemy has a health component, and that has a baseHealth, and a currentHealth

You CAN do anything you want though. It is easy enough to pivot and refactor as you go. It will happen regardless of how well you plan.

[queen adder]

that is what I get its gonna have differnet script for different enemy prefab

but how would i acess the variables from another script though

[ivory bobcat]

Multiple instances of one script? 🤔

[ivory bobcat]

With proper referencing

[summer stump]

We have linked you this previously
https://unity.huh.how/references

Serialized Reference when possible

When not, then you are instantiating. And Instantiate returns a reference

For damage based things, often you get the reference from things like OnTriggerEnter or raycasting (and other spatial queries)

[queen adder]

Okay so serialized reference

[ivory bobcat]

Give an example of what you'd want to access and how the two objects relate.

[summer stump]

That only works before you hit play of course

[rich adder]

at times its not possible to use it, if you click https://unity.huh.how/references/serialized-references
you can see many examples where you cannot. One example is you cannot drag any scene objects into a prefab

[queen adder]

I want baseHealth to be accessed from the enemy when the enemy collision with base i want it to -1 baseHealth from the enemy scritpt. I also need maxBaseHelath in another scene for upgrades

[queen adder]

Ill look into what it does exactly

[queen adder]

It does what i need it to do

[summer stump]

Then do:
OnCollisionEnter
collision.gameObject.GetComponent<Health>()

GetComponent (and preferably TryGetComponent) are exactly what you want for that

[queen adder]

private void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.collider.CompareTag("enemy"))
    {
        takeDamage();
        BasePlayerPrefs.setMaxHealthToCurrent();

    }```

that is what i got currently Im gonna have to completely revamp everything

[summer stump]

You need the ``` marks at the end as well for formatting btw

[queen adder]

i fixed it

[grave furnace]

Guys i got a fast question, im watchin a tutorial and i just realized that something is worgn cause the dashCounter will never be > 0 and <= 0, right?

oh no

it reduces its value

would it change anything if i put this if (dashCounter <= 0) under the other if instead of inside?

[teal viper]

What other if statement?

[somber herald]

Whats the best way to convert the Input.GetAxisRaw to direction?

[grave furnace]

thats the full code i guess

except for the variables

[teal viper]

Create a new vector from it.

[summer stump]

Who made this tutorial?
Seems so overly complicated for no reason

[somber herald]

OOH TY

[grave furnace]

Jake Makes Games

[teal viper]

And where do you want to move the if statement?

[grave furnace]

lemme make my own code so u can understand it better

but first

[summer stump]

Presumably right after the dashCounter > 0 check

[grave furnace]

using UnityEngine;
using UnityEngine.UIElements;

public class movement : MonoBehaviour
{
    [SerializeField]
    public float moveSpeed;
    public Rigidbody2D rb;
    public Vector2 moveInput;

    private float activeMovespeed;
    public float dashSpeed;

    public float dashLength = .5f, dashCooldown = 1f;

    private float dashCounter;
    private float dashCoolCounter;

    void Start()
    {
        activeMovespeed = moveSpeed;
    }
    // Update is called once per frame
    void Update()
    {
        moveInput.x = Input.GetAxisRaw("Horizontal");
        moveInput.y = Input.GetAxisRaw("Vertical");

        moveInput.Normalize();

        rb.velocity = moveInput * activeMovespeed;

        if (Input.GetKeyDown(KeyCode.Space) && (dashCoolCounter <= 0 && dashCounter <= 0))
        {
                activeMovespeed = dashSpeed;
                dashCounter = dashLength;
        }

        if (dashCounter > 0)
        {
            dashCounter -= Time.deltaTime;
            if (dashCounter <= 0)
            {
                activeMovespeed = moveSpeed;
                dashCoolCounter = dashCooldown;
            }


        }

        if (dashCoolCounter > 0){
            dashCoolCounter -= Time.deltaTime;
        }
    }
}
``` thats my actual code but i guess im missing something here

omg i pasted too many things

[teal viper]

The dashCounter relates stuff looks the same to me.

[grave furnace]

but for somewhy my dumb square player isn't dashing 😔

[teal viper]

You have some other differences compared to the original code though.

It's likely that that's the cause.

[grave furnace]

ye i don't see why this'd cause it but i'll try

[teal viper]

Add debug logs to your code to see what's happening.

Or step through it with a debugger

[grave furnace]

tbh i don't have idea how to debug my code with visual studio code

i had issues trying to use visual studio cause i don't have 2019

gotta search abt it

[grave furnace]

    [SerializeField]
    public float moveSpeed;
    public Rigidbody2D rb;
    public Vector2 moveInput;

    private float activeMovespeed;
    public float dashSpeed;

    public float dashLength = .5f, dashCooldown = 1f;
    private float spinSpeed = 1f;
    private float activeSpinSpeed;
    private float dashCounter;
    private float dashCoolCounter;

    void Start()
    {
        activeMovespeed = moveSpeed;
        activeSpinSpeed = 0;
    }
    // Update is called once per frame
    void Update()
    {
        moveInput.x = Input.GetAxisRaw("Horizontal");
        moveInput.y = Input.GetAxisRaw("Vertical");
        rb.rotation += activeSpinSpeed;

        moveInput.Normalize();

        rb.velocity = moveInput * activeMovespeed;
        

        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (dashCoolCounter <= 0 && dashCounter <= 0)
            {

He's rotating around a corner (the object is a square)

can i change its rotation point or whatever is that to the center of the square?

[thorny hamlet]

how to fix this bug guy pls help

[rich adder]

surely you meant to have IEnumerator

it isn't a bug lol

[thorny hamlet]

oh

ok

thank

mb

[rich adder]

please use site for large code https://gdl.space

[grave furnace]

oh kk

[mint remnant]

is there a way to calculate a max velocity before it's too high to miss a collision? Currently playing with dropping balls from random heights with UseGravity on and emperically finding the value to be about 29, but that might be fps dependant too

[radiant frigate]

https://gdl.space/wuyaxoqole.cs does someone know or understand why the bullets appear rotated on the map?

the code that makes this thing happen is on line 75 towards the ending

but i shared everything in case it might be other thing causing trouble

[rich adder]

your scale is non-uniform

[radiant frigate]

i need to check on what that means

brb

[radiant frigate]

okay, and is that a bad thing?

[rich adder]

for rotation it is

it skews the object

[radiant frigate]

skews?

and how can i make it uniform?

[rich adder]

imagine your object is inside a cube, as you rotate it starts turn into like a trapezoid type shape

[radiant frigate]

that happens if i only rotate the z ?

[rich adder]

make the numbers the same , eg (0.5, 0.5, 0.5)

[radiant frigate]

the x,y,z?

but then i cant make it point towards the player right?

[rich adder]

wdym

[radiant frigate]

okay wait

what line are you looking at?

75?

[rich adder]

wait

i just saw the code

i was talking about the scale

[radiant frigate]

oh

yeah

lmao

i rotate it via code so i can set the velocity

[rich adder]

you are talking about the Instantiate?

[radiant frigate]

nope

the line below that one

the rotation of the parent is 0,0,0

so that shouldnt bother it

[rich adder]

are you talking about bulletHolder

[radiant frigate]

yes

[rich adder]

thats not rotating the bullet tho

wait

[radiant frigate]

in the z axis it is

[rich adder]

ops misread that

did you fix the scale

[radiant frigate]

what do you mean?

[radiant frigate]

ohhhh

done

[rich adder]

you have to do it on the prefab

[radiant frigate]

let me try now

yes i did

okay did it and checked

but it still rotates on the x,y

[rich adder]

wdym

[radiant frigate]

in the rotation the x and y still gets modified

even if it shouldnt

[rich adder]

Ahh i see what you mean now.. I thought your spheres were distorting

just realized its 2d so it probably didn't matter

[radiant frigate]

indeed its 2d

[raw token]

On a side note, I don't understand why direction.z is in here... That's the distance to the player on the world z axis, which seems a little strange to use in a calculation for degrees, no?

bulletHolder.transform.up = Quaternion.Euler(0,0,direction.z-30+ (30*i)) * direction;

I don't think it's what's causing the problem as it's still a rotation around the z axis, but it gave me pause

[rich adder]

yeah that looks wrong

[radiant frigate]

thats the way i know in what direction he is

[rich adder]

*direction is causing the issue i think

[radiant frigate]

hmmmm, how is direction.z rotating the x,y tho?

[rich adder]

I think you can just do AngleAxis

[radiant frigate]

what does angleaxis do?

[rich adder]

try var upDirection = Quaternion.AngleAxis(direction.z - 30 + (30 * i), Vector3.forward) * direction;

[radiant frigate]

so instead of euler AngleAxis

[rich adder]

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

[radiant frigate]

okay

nope, that didnt do the trick

[raw token]

What do you get if you log direction.z?

[rich adder]

does it do the same thing?

[radiant frigate]

yep

[radiant frigate]

-1

which makes sense

why am i even using direction.z for that?

when its 2d

what did i cook? 😭 💀

[raw token]

My guess is that's part of the problem. You're orienting the object's y axis to a vector with a non-zero z component, so it's rotating on the x and y axis to point in a direction off of the x/y plane

direction.z = 0f;
// ...
bulletHolder.transform.up = Quaternion.AngleAxis(-30 + (30 * i), Vector3.forward) * direction;

[rich adder]

couldn't u just 0 out the z direction

[raw token]

sure that would be better 😁

[radiant frigate]

i do not understand

that is some big words

what does orientation the objetc´s y axis to a vector with a non-zero z component?

my guess si that im trying to rotate it on the y with a -1 z

but i do not see how im rotating it in the y

because im doing that transform.up = "the math"?

[raw token]

Because the player and this game object are at different z positions (which is your "depth" in a 2D game), the direction vector is not just pointing to the player on left/right (x) and up/down (y) axes, but also towards or away from the camera.

transform.up = stuff is setting the game object's rotation such that it's positive y axis is aligned with stuff, so if you assign to it a vector which is pointing towards or away from the camera, then the object is going to tilt towards or away from the camera

[radiant frigate]

okay

i seem to understand it now

and what did navarone miean with 0 out the z direction

[rich adder]

look at the code they sent

[raw token]

Before I was creating a new vector which used just the x and y components from direction and 0 for the z. Nav was suggesting to just keep using the current direction vector and set it's z component to 0f. They achieve the same thing, but mine was extra typing and extra work for the computer

[radiant frigate]

and how do you set it to 0 ?

i wanted the z so it has depth, for not overlapping or clipping

in case you mean to set the z to 0 in the inspector

[radiant frigate]

if not this is irrelevant

[raw token]

And they do - the objects are still at different z positions, we're just throwing out the z component of the direction vector in this code because it's not useful in this calculation, and is in fact messing it up :P

direction.z = 0f;

[rich adder]

for 2D just use the Order in Layer on Sprite Renderer

also you wouldn't mess with Z for rotation target in 2D

[radiant frigate]

oh

its edited

i thought the direction.z = 0f;

was already there

and he meant other thing*

[radiant frigate]

it did not solve the problem sadly

[raw token]

womp womp 😦

[radiant frigate]

wait

AINT NO WAY

I JUST USED THOSE WORDS

[raw token]

hahaha

[radiant frigate]

lmao

[raw token]

trippy

[radiant frigate]

wait

i think it actually solves it

but since i have 2 enemies i just changed 1 of them in code

so that could be it

lemme check

[rich adder]

the code should 100% work

[radiant frigate]

it does indeed work

maybe just make it a singleton

[fervent abyss]

subscribe in onenable and unsubscribe ondisable

[languid spire]

how are you subscribing? show code

[raw token]

Like... to have it move horizontally as if it were rolling?

[magic panther]

no, offset by a value on the X axis, like if you extend your arm and rotate your shoulder, your hand is rotating with the shoulder but offset from it by your arm's length

idk how else to describe it

I think a drawing could do

moving the object or rotating it keeps the offset

so just local positioning relative to rotation

in other languages I'd use sin and cos for this, but idk how about unity objects

Hello! I'm trying to make simple 2D movement and my player can jump infinitely. I made a private bool called "isGrounded", a public LayerMask for whatIsGround, a GameObject for the groundCheck and a public float for the checkRadius, but now after all these things I do not know what to do in order to check if the player is on the ground or not. Could anyone help me?

nevermind, i found out

why does my rb.AddForce work in the editor but not in the android build?

the code works right, but the it doesnt move when i play it on my phone after building

[raw token]

You can still use Sin and Cos in Unityland™, but I'm still not totally clear on what you're trying to achieve...

My best interpretation is that you're trying to keep ice cream man's "shoulder" in the same place when the arm/weapon swings around?

[fervent abyss]

void OnEnable()
    {
        EventHolder.mouseButtonClicked += (MouseButtonType button) =>

            StartCoroutine(ButtonClicked());
        };
    }

    void OnDisable()
    {
        EventHolder.mouseButtonClicked -= (MouseButtonType button) => { };
    }
```...

[loud mango]

help me with this please 🙏

[random plaza]

Heya. I'm unfortunately drawing a blank on how you can get one GameObject to create a "pointer" object to another in the world. I have an empty "Ground Point" object which I want the camera to follow, but which isn't a child of the camera, and I don't think it's wise to call GameObject.Find on every frame to locate and point at it.

Ideally I'd be able to create a reference to the world object so that the camera's idea of the ground point's position updates whenever it's moved instead of having to write code to continuously locate and copy its position

[magic panther]

something like this. Had to look for the Deg2Rad thing tho

[random plaza]

Anyway, short version, if any of you remember how to declare a pointer to a GameObject lmk

[languid spire]

there is your problem. You cannot unsubcribe a lambda function

[loud mango]

sensei, can you help me?

[loud mango]

with this

[raw token]

The problem you have described is not common - there is no logical reason for AddForce() to behave different in an Android build than a desktop build. There may be an issue in your code, but no one can provide feedback on that if you do not provide your code. Given that the issue is specific to a platform, you might ask in the channel specific to that platform - #📱┃mobile. But these are quiet hours. I would not expect an immediate response

[loud mango]

i yesterday did, everyone said it was not a problem with the code

[fervent abyss]

i just subscribed in void Start() and get the same problem, and i have a separate method now (no lambda)

[languid spire]

no. I tried to help you with this yesterday and you just ignored my question. Also #📖┃code-of-conduct

[loud mango]

i debuged on every move and it was confirmed

oh, it was late and i was probably sleeping on my chair 😭 sorry

[raw token]

Sure sure... But this still doesn't quite tell me what you're trying to achieve with this code... If this code is not accomplishing it, then me parsing it to figure out what it does will not help. Are you trying to keep the "shoulder" in the same location?

[languid spire]

the only thing I can suggest is add a null. check for button in the method

[magic panther]

You don't need to worry about it anymore tho, I fixed the initial issue, now it's dowwn to tweaking

[raw token]

I will say that if keeping the shoulder stationary was the goal, an easier way to achieve it is to create an empty game object and position it where the shoulder should be. Then you use it's transform.position in RotateAround() to rotate the arm/weapon.

But I'm glad you found a solution, in any case 👍

[serene briar]

How do I change variables for different game objects using the same script? I want the “myMass” variable of object one to be 10, and the “myMass” of object two to be 5. Is there any way to do this easily? I tried a private serialized field to change them in the inspector, but it just outputs 10 twice. I’m also trying to avoid “if (this.name ==…)” because if I have a lot of objects, that would clutter my void Start.

[languid spire]

private serialized field should work. show !code

how would I store a clone of a prefab in code? I'd like to copy a prefab to instantiate later, but I'd rather not instantiate this prefab in the scene.

[serene briar]

I do have an error saying so it was likely that then, thanks.

[languid spire]

presumably this is at runtime, not in the editor

[eager spindle]

yep

[radiant frigate]

is there any way of making enemies not overlap on top of each other or go in hords that are too concentrated?

that are not*

[languid spire]

I don't think it's possible, normally to clone I serialize/deserialize but you would still need a gameobject to deserialize to

[eager spindle]

working with someone else's code right now, they're hardcoding a prefab in the interaction system 🤦‍♂️ I'm making it such that it changes the text in their hardcoded button so the interact system displays the name of the interact button correctly

[languid spire]

you probably want to use one of the Raycast methods on your generated enemies positions before you instantiate

[radiant frigate]

could you elaborate on it a bit

well let me elaborate first because maybe we dont mean the same thing

[radiant frigate]

they follow the player with a vector that substracts their position from the players one, so more often than not they end up all in the exact same spot

[languid spire]

so you are not talking about creating the enemies, just when they follow the player they all converge

[radiant frigate]

indeed

[languid spire]

so give each enemy a different speed within a range

[radiant frigate]

basically that they stop being like in left side, and more like in right side

but then they will still end up in the same point once all of them reach the "min distance for attacking"

maybe that once they reach the min distance, make them move a bit randomly to attack

some would still overlap but overall not that bad

imma try that

[languid spire]

yeah, once they reach min distance you can get them to move in a circle around the player

[radiant frigate]

how could i make them move in a circle

i have thought about that but cant think of a way of coding that behaviour

[languid spire]

it's simple to get the points of a circle with radius of min distance from the player, so just use that to guide your enemies

[radiant frigate]

radius of min distance

yes i understand the concept

i will see if i find anything on how to determine those points

[languid spire]

,basic math

[radiant frigate]

i dont think that i can get each "red line" position with basic math

well i probably can

but i do not know that math

so i need to first learn it

[languid spire]

,this should help

god damn thats some gorgeous math

Greetings all, I am following the Unity Essentials tutorial, I'm currently on mission 4, lesson 3.5 (Collect the collectible - Destroy the collectible)
I am given the following code for the script of the relevant interaction with the gameObject:

private void OnTriggerEnter(Collider other)
{
//Destroy the collectible
Destroy(gameObject);
}

which is copied into visual studio as the tutorial instructs
however, once I go back into Unity I am given this error in the log:
"error CS0106: The Modifier 'private' is not valid for this item"

I have tried changing the method to public and even taking off that modifier alltogether, but I still get an error on that line
the script seems to be named correctly (as Collectible.cs, as instructed)
I do have a bit of programming background, just not that familiar with C# and with Unity obviously, so I'd appreciate a few pointers on what's happened here

I'm not sure whether it's a mistake in the tutorial, or a visual studio bug, or maybe I've written the code wrong somehow

I did change the collider of the gameobject to a trigger previously as the tutorial instructed

is this an issue where I need to declare the method in the public field and the tutorial doesn't mention it?

usually that's how it works in C

[radiant frigate]

(idk if i should or not "ping you" , but i wanted to show you my code and how i used it to determine close points and select one at random) https://gdl.space/deduhulore.cs

[keen dew]

You've put it in a wrong place

[languid spire]

this would suggest to me that you have nested the method inside another one

[loud sage]

that's odd, it's what the tutorial gives me to copy

[languid spire]

but where did you put it?

[loud sage]

it is inside the update loop

[languid spire]

wrong

[loud sage]

my whole code:

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

public class Collectible : MonoBehaviour
{
public float rotationSpeed;

// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    transform.Rotate(0, rotationSpeed, 0);

    private void OnTriggerEnter(Collider other)
    {
        //Destroy the collectible
        Destroy(gameObject);
    }
}

}

[languid spire]

yep, nested, it's in the wrong scope

[loud sage]

I am dumb

alright the error's gone, I had copied the method on autopilot

works in play mode too 👍 thx

[languid spire]

lesson learned, I hope. Coding is NOT something you can do on 'autopilot'

[loud sage]

I'll try not to skip bullet points on beginners' lessons 🫠
I had thought the wait for a trigger would be something to be done inside the update loop, but it makes sense that it would be async

Hey guys! I'll try to explain what I want: I have a player that the camera should be watching. But the player appears at a certain button, that is, initially he is not in the scene. I press a button and the player appears in the scene and the camera should be working and watching him.

In general, to make it convenient, we consider the camera at the GTA 5

But the problem is not with the camera itself, but that I want to assign it to a prefab that is not in the scene.

if i write this Vector3[] bestPoints = new Vector3[]; im creating an array right?

how can i set it to a size of 0?

technically it wouldnt matter since i can always modify its size

https://gdl.space/ajamoturin.cs

i want it to be resizable so it only takes the vector3 that meet the criteria

[keen dew]

You can't modify an array's size. If you need that then use a List

wasnt it the other way around? a list isnt modifiable and an array is?

no

Take a closer look

lol ok

ye

[radiant frigate]

hi again! im getting this error that says that the index is out of range, but when i click on it it redirects me to a line that starts a coroutine, could this be because im using a list in the coroutine?

[barren vapor]

you're summing 2 strings

same effect like Javascript

[rare basin]

yea i thought i twill add together

then print the float

mb

[barren vapor]

index out of range is always smt with a loop/list

[radiant frigate]

okay

[radiant frigate]

https://gdl.space/epewapezuc.cs could you help me deducin where it is happening?

[modest dust]

Take a look at the stack trace in the error and click the top-most hyperlink

[radiant frigate]

stack trace?

[modest dust]

Sometimes clicking the error itself may point you to the wrong place

[barren vapor]

which line is it

[radiant frigate]

thats the coroutine itself

[modest dust]

The list of "code places" from where the problematic piece of code was called

[radiant frigate]

it doesnt say which line

[barren vapor]

click on the error

it always shows the line

[radiant frigate]

https://gdl.space/wecifiwusa.cs it brings me to line 72

that is the full script

[radiant frigate]

no clue what that is

[modest dust]

I'd show you an example but I'm currently waiting for a train

If you click the error and look at the full description, there should be a couple of links pointing to different places in your code

The top-most one is where the error took place

[radiant frigate]

left or right?

[barren vapor]

just screenshot it

[radiant frigate]

because if i left click it leads me to the code and if i right click nothing happens

[modest dust]

Left-click once

[radiant frigate]

here it is

[modest dust]

on the bottom of the console there's an expandable window

Where the full description of the error is

[radiant frigate]

ohhhhhh

132

line 132

and line 80

[barren vapor]

So this
var choosenVector = bestPoints[Random.Range(0, bestPoints.Count)];

[radiant frigate]

that has to do with the return on line 132

yes

but how is that taking a number out of range?

isnt 0 = to the first object?

[barren vapor]

use

var choosenVector = bestPoints[Random.Range(0, bestPoints.Count - 1)];

[radiant frigate]

maybe because its empty sometime?

[barren vapor]

Count = amount of items. So if there's 1 item, then it starts at 1.

[radiant frigate]

ohhhh

okay okay

[modest dust]

Shouldn't the Random.Range int overload be max exclusive?

[barren vapor]

hmm, I'm not sure. Might be yeah, but he can try it this way

[radiant frigate]

yes

it should

but it works

i worked with the max exclusive in mind

since b4 hand i had it being added +1

[barren vapor]

weard

[radiant frigate]

but then i remembered that (wrong btw) list work like 0=1st object so i let it be the same

lying

i dont even remember anymore

i just know i messed around and that its supposed to be max exclusive

[winter tinsel]

hello, im trying to instantiate an object at my rigidbodys position but just a little to the side

allright

[mint lodge]

Hey guys

[modest dust]

Cast to Vector3

[winter tinsel]

im on 2d but okay

[mint lodge]

I have a Missile Launcher in my 2D Platformer, it works correctly, but the Missile which is only supposed to Explode upon contact with Tag Player or Ground, also explodes when it goes out of the Main Camera view

Does anyone know why?

[modest dust]

Then to Vector2.

But it doesn't matter

[winter tinsel]

it works kinda but the offset is too much lol

gimmie a min

[barren vapor]

Can you share the code you're using?

[mint lodge]

For the Missile or Launcher?

[barren vapor]

missile

[mint lodge]

Tried using OnBecameInvisible to force delete it when it's out of Camera View but it still Explodes()

Oh, I think I know what the problem is

I used collision.collider

It should be collision.gameObject.CompareTag

It's evaluating to 0 || 0 no matter what it collides with

[stuck palm]

what's the difference between using a return type and using an out parameter?

[barren vapor]

rubber duck concept helped once again

[mint lodge]

Thanks for being my rubber duck 🦆

[teal viper]

Not much difference.

[stuck palm]

they both achieve essentially the same thing right? what about a ref parameter?

[teal viper]

Ref allows you to pass a value type by reference.

[winter tinsel]

works, how can i edit the rotation?

[stuck palm]

how does that work, then? it lets you use a field for example as a reference and then augment that field?

[winter tinsel]

its quaternion, i tried to do the same thing as the position but it didnt let me so how do i edit it?

[teal viper]

Yep

is there a better way to save the value of sliders

if there were more sliders here, would i write them all one by one

[modest dust]

Depends what you want to do. You can convert Euler to Quaternion

[stuck palm]

freaking epic

[dark cove]

Hi guys! I'm new to this... Like all of these...

I just downloaded Unity, and I'm requested to download the editor too. Am I on track?

[winter tinsel]

just from the angle that it spawns at a slight deviation

[eternal needle]

Yes but in cases like these it doesnt really matter. If you had a ton of settings then I'd look into using some collection to store these all.
About your question for their being a better way, if this suits your use case and works then it's fine. I personally wouldnt go with playerprefs

[winter tinsel]

how would i edit the angle that it spawns at

[tough phoenix]

what are you using? json?

[eternal needle]

Yes, json is just a file format though. I do suggest writing to file. If you ever need to save custom data then you'll have to write to file anyways.

[tough phoenix]

thanks

[vital yoke]

can someone tell me what is wrong with my code, im a beginer and I really dont get why it doesnt work

[slender nymph]

start by configuring your !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

[cosmic dagger]

Also, you should explain what you're trying to do and what is happening (or not) instead . . .

[languid spire]

Also, it would appear you have made absolutely no attempt to debug this code

[slender nymph]

1. this is a code channel
2. don't zoom your game view, it doesn't scale well

[eager spindle]

you should probably save the code(ctrl s)

[arctic ibex]

I'm trying to Lerp/Slerp a rigid body using a tutorial and its telling me "cannot implicitly convert type Quaternion to type float." The slerp thing says it wants three agruments (quaternion, quaternion, float) and I have given it three arguments (quaterion quaterion float.) I can't figure out what th eproblem is

[verbal dome]

2D rigidbody's rotation is a float

[arctic ibex]

oh, alright. How do I fix that? cause I have to use rigidbody for thephysics to work properly dont i?

[verbal dome]

You'd want Mathf.LerpAngle/MoveTowardsAngle/SmoothDampAngle

[arctic ibex]

oh

alr thx

[verbal dome]

A more physically correct way could be to use rb.angularVelocity instead

Not sure if changing rotation directly can cause oddities in 2D

[zenith crown]

So im trying to make a FreeLook function for my game but im having trouble to make it reset to 0 in rotation when done freelooking

[verbal dome]

MoveTowards is not for quaternions

[slender nymph]

there are several things wrong with that. first, localRotation is a quaternion, not a float. and you shouldn't be using the members of a quaternion for logic because they are not represented in degrees

[languid spire]

localrotation.y is NOT an Euler angle

[zenith crown]

Yeah i have no clue what im doing im js guessing my way forward

[slender nymph]

there are beginner courses pinned in this channel, and the pathways on the unity !learn site are a great way to learn how to use the engine. perhaps you should start there instead of blindly guessing

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[round plover]

yeah

[languid spire]

then spend some time learning, if you dont know what you are doing each line of code should take you at least 10 minutes to write whilst you read and understand the documentation

[zenith crown]

i took a 4 hour and a 12 hour course for unity but they didnt speak once about quaternions so thats why i was guessing my way forward thinking it was like any other transform, im gonna read some documentation about it now tho

[languid spire]

pretty awful courses then as Quaternions are central to the Unity system

[zenith crown]

Yeah they were more C# focused than unity focused

barely a unity course

[eager spindle]

you currently have the Unity Hub. The Unity Hub manages different versions of Unity Editors(and their extensions), It's normal to have one version of the hub and multiple versions of the unity editor.

[dark cove]

Oh! Thanks... I will work on getting an editor that works for me. Is the different editors laptop specific...?

[eager spindle]

Nope

The Hub detects which device you're on and installs the correct editor

For now its best that you install the latest LTS version

[tough phoenix]

Inventory script has a function with 2 parameters but it doesn't appear in the editor

[formal venture]

is there any better way to write this? Like with some Mathf function or smth?

[slender nymph]

https://unity.huh.how/unity-events/method-requirements

[tough phoenix]

thanks

[slender nymph]

you can use Mathf.Max or Mathf.Clamp

[languid spire]

you can use clamp

[eager spindle]

theres mathf.max, returning the higher of 2 numbers

[formal venture]

oh okay thanks

[languid spire]

but it is not better

[eager spindle]

though your current code works fine as you might want to have other functionality once your ammo in clip runs out

e.g. playing a click sound to signify you've run out of ammo, automatically reloading,

[formal venture]

its only there to be sure i don't have negative ammo in my clip, the things u said are handled by other elements

[radiant frigate]

https://gdl.space/awenapajin.cs i am calculating random dots around a circle circumference that has its origin at the player , and calculating the dot product respective to the position of the enemy so i can assing places to the enemy to move, i think the dot product is somehow taking into acount the positions at the other side of the circle

green = player
red = enemy
blue = possible places

is vector2.Dot supposed to work like this or am i missing something?

[zenith cypress]

Well a dot product doesn't use positions, it uses directions. You are giving it a world position as the second value, so the offset nature of points[i] is making it act weird.

[radiant frigate]

i understand

ty!

Vector2.Dot(-direction, player.transform.position-points[i])

this should work?

okay i corrected it

Vector2.Dot(player.transform.position-transform.position, player.transform.position-points[i])

but i still have the problem with some guys

[shell sorrel]

is player.transform.position-points[i] a direction?

[zenith cypress]

Sure, although that just removes the player.transform.position + you have before, so you probably just want to not do that, and then pass in points[i].normalized as the second.

[shell sorrel]

like is its zero the same zero as your direction?

[radiant frigate]

points[i] is a vector 3

[shell sorrel]

vector3 can be used to show a position or a direction

[radiant frigate]

but im doing player.transform.position - points[i]

which should give a direction

i think

[shell sorrel]

yes p2 - p1 gives a direction pointing from 1 to 2

[radiant frigate]

i use the player.transform.position so it knows where the circle " origin" is

[shell sorrel]

though the dot product wants 2 directional vectors and returns a float that more or less tells you have similar the facing of these 2 vectors are

[radiant frigate]

yes

[radiant frigate]

the first one is player.transform.position-transform.positionand the second oneplayer.transform.position-points[i]

i think they should be directional

[shell sorrel]

the naming of that makes me belive they are not

[radiant frigate]

how can i distinguis a directional vector from one that is a position

[shell sorrel]

well i am going with that you called it position or point

so assuming that is a point in space,

[radiant frigate]

yes it is

or it should

[shell sorrel]

ok, but what i am saying is most uses of the dot product you are going to want 2 normalized directions

[radiant frigate]

https://gdl.space/ogomesimoh.cs

oh so i should normalize them

[shell sorrel]

oh lets step back, i mis read things

[queen adder]

In math, points and vectors are distinct objects, but in unity you just interpret a vector as a point. Only way to keep track is with context and naming conventions really

[shell sorrel]

so used to have spaces around operators i read player.transform.position-points[i] as 1 var not 2

[radiant frigate]

ohhhh

no its a calculation

that uses 2 vectors

player.transform........

and points[i]

[shell sorrel]

yeah just me not fully paying attention, so that should work, since its comparing the play pos to current pos, with the player pos to a poiunt

i would normalize the vectors after subtraction though

[zenith cypress]

btw, another small thing, you don't need the -1 here Random.Range(0, bestPoints.Count - 1). Int random range is already max exclusive (if you didn't know)

[radiant frigate]

yes, i had that same discussion earlier

#💻┃code-beginner message

[zenith cypress]

So is this what you are wanting (green is the final point)

[radiant frigate]

yes

something like that

btw amazing name and pfp

lol just saw it

[zenith cypress]

https://nombin.dev/8ev14zsjvhy79i3sdfpjxh7d

If you want to play with it ^

[radiant frigate]

cool visuals

but i think that code is too advanced for me at the moment

[zenith cypress]

Not sure what would be too advanced about it. It's basically your code, just slight tweaks and a direction fix.

If you have questions about it, ask em

[radiant frigate]

what is mathf.lerp?

and what happens if you writeusing var _

[zenith cypress]

Lets you get a value between a and b at a certain percentage

[radiant frigate]

why that name

[wintry quarry]

linear interpolation

[zenith cypress]

lerp(0f, 2f, 0.5f) -> gives 1.0

[radiant frigate]

interesting

i will surely check into that

[tepid cove]

id like help leading me in the right direction, im a complete beginner at coding. i want to have "keypress combos for ability's" but im not sure how id go about creating that. for example "Z,X,C,V" being they keys and if "Z,Z,C,X" is pressed in that order you will you an ability. how would i go about doing this? or if there is a name for this kind of thing so i can search for other people implementing it and hopeful learn how to do it

[zenith cypress]

that part is because I didn't want to give a name to the object you have to dispose due to the using. So that trick is just to be lazy (it's not a discarded name or anything, it's just the smallest you can go lol)

[radiant frigate]

oh

i dont know the code confuses me a bit

i also am a bit sleepy as one may say, so, perchance that might be the issue

btw what do you mean with line 41?

[wintry quarry]

this is something called "input buffering". Basically you listen for input, and whenever a button is pressed you add it to a list. And every time you do that, you also check it the list against the "recipes" you have for moves

if it matches, you do the move

if too much time passes you clear the buffer

it's best implemented with a State Machine

but if you're a complete beginner at coding, this is probably beyond your abilities at this time

you should probably focus on the basics for now and work up to something like this

it's very common for fighting games for example

[radiant frigate]

oh man i would love to learn that and i know i should

but every tutorial on yt thinks that the viewers already have x amount of expertise

if you had a doc that is good i would love it

i cant manage to find good things about that

[wintry quarry]

to be clear the state machine is just the framework on which to build this solution. It's not the solution itself.

[zenith cypress]

The same space being like both being proper directions, didn't know how to word that. In the image the left is the world points, the right is what line 42 is working with. Normalizing just puts them onto a 1 unit circle, and point is just a circle position already, so you don't have to offset by a world position (like you had prior) for the dot.

[radiant frigate]

like i had prior?

im not understanding rn

i understand what world point is but i dont know how that would help me

also, this happens, it somehow takes a position that shouldnt be achievable

[zenith cypress]

What's not achievable about it?

[radiant frigate]

this direction

since it isnt at radius distance

something must be off with the code

but i cant manage to see what it is

[zenith cypress]

Not sure what I'm looking at. The radius you had (in your code + original image) was between the player and the enemy. What is it doing vs what are you expecting it to do? I'm working with what I was given lol

[radiant frigate]

i basically want it move to a position in the " circumference perimeter" that is close to its position ( thats why the dot product)

and what it does, is going to a position (sometimes not even in the perimeter) on the opposite side of the circle

i dont know if it makes sense what im saying

srry but i cant access the code now, in case its needed

[ivory breach]

Guys, is there a way I can store all elements of the materials array from a mesh renderer via code regardless of size?

[frosty hound]

Why would you need a separate collection to store them, when you have them right there?

[wary sonnet]

have anyone used Opsive universal character controller ?

[wintry quarry]

yes, an array of course. But as Osteel mentioned the Renderer already has an array, there's usually not a good reason to have your own long-lived copy

[wary sonnet]

I am experiencing a big amount for proccesing time because of animation and physics kind of overriding or having issues in rendering the final simulation of the character ig, it's all scripts prob that's all I know

[ivory breach]

It's because I'm going to change all materials in the array to a different one and then back, to produce a flash effect

[wintry quarry]

looks like they have their own support forums and discord server: https://opsive.com/support/

[frosty hound]

Might be easier to just toggle mesh renderers. Or change the materials themselves. But if you want to do it with different materials, then you can create a separate array and store them, sure.

[wintry quarry]

ok so... use an array, that's what the renderer directly gives you back

what's wrong with that?

[wary sonnet]

wow, I d'be dumb to not found that before, thanks :D

[ivory breach]

I mean I want the array to be able to add any number of materials in the model

[wintry quarry]

yes arrays can be of any length

enemyMaterials = myRenderer.materials;

it's really not clear what you're asking

Have you learned how to work with arrays and the basics of C# yet?

[ivory breach]

I know quite a bit about C#, but arrays are something I'm still improving on

[wintry quarry]

if you don't know arrays you have a lot to learn about the basics of C# still

[ivory breach]

Regardless, would this add all of the materials the attached object has?

[wintry quarry]

yes...

[ivory breach]

Lemme check

[wintry quarry]

don't forget to save your code

also gameObject isn't necessary

[ivory breach]

Huh, it did add them

[zenith cypress]

@radiant frigate well when you wake up show some more examples to make it clearer what you want or similar. Was playing around with it and got it to do the same logic with less going on.

public Vector2 GetPointAroundCircle() {
    var playerPosition = _player.position;
    var position = transform.position;
    var distance = Vector2.Distance(position, playerPosition);
    
    // move both positions around world origin so atan2 works properly
    position -= playerPosition;
    playerPosition = Vector3.zero;
    
    // put the enemy on the circle, atan2 takes a position and gives back the radians
    // on a unit circle of where it would be on it
    var circleDirection = position - playerPosition;
    var positionOnCircleRadians = Mathf.Atan2(circleDirection.y, circleDirection.x);
    
    // get an offset to apply to the enemy's circle radians
    var angleRange = _angleRange / 2f * Mathf.Deg2Rad;
    var offsetRadians = Mathf.Lerp(-angleRange, angleRange, Random.value);
    
    // get a new offset circle position
    var positionOnCircle = new Vector2(
        Mathf.Cos(positionOnCircleRadians + offsetRadians) * distance, 
        Mathf.Sin(positionOnCircleRadians + offsetRadians) * distance
    );
    
    // take the circle position and put it back around the player
    return positionOnCircle + (Vector2)_player.position;
}

[ivory breach]

That was... a lot simpler than I expected

I thought I add to do the 'for' or 'foreach' loop stuff

[radiant frigate]

hi! im not asleep but i will go soon

i dont think im in condition of checking the code

but if you want i can add you

[grizzled island]

i did :NumberFormatter.Format(1350)
why it returns 1K not 1.35K ?

using System.Collections;
using System.Collections.Generic;
using Unity.Mathematics;


public class NumberFormatter
{
    
    static long[] powers2 = {1000, 1000000, 1000000000, 1000000000000 };

    static char[] abbreviations = { 'K', 'M', 'B', 'T' };
        
    
        

    static public string Format(int number)
    {

        int absulute = math.abs(number);

        if (absulute < 1000)
        {
            return number.ToString();
        }
        
        float power = math.min(math.floor(math.log10(absulute) / 3), abbreviations.Length);
        int power2 = Convert.ToInt32(power - 1);

        double num = (double)absulute / powers2[power2];
        
        num = math.floor(num * 100) / 100;

        string formatted = num.ToString("0.##")  + abbreviations[power2];

        return formatted;
    }
        

    
    
}```

[wintry quarry]

Why not debug the code and find out?

attach the debugger and go through step by step, or add log statements at each step and see where things are going wrong

[grizzled island]

i did

[wintry quarry]

and what did you learn

[grizzled island]

the problem is in ToString

[wintry quarry]

how do you know that

what was the value of num before the ToString?

[grizzled island]

1.35

i returned num.ToString() and it gives 1

[wintry quarry]

https://dotnetfiddle.net/s027Jp
Seems it wasn't 1.35

because that works fine

[grizzled island]

NumberFormatter.Format(1350)

[wintry quarry]

Yes I'm aware that's what you did

but 1.35.ToString("0.##"); doesn't give 1

so num was likely not 1.35 as you said

[grizzled island]

hmm its strange

[wintry quarry]

So you need to debug your code

[polar acorn]

Curious how you expected num to be a value with decimals after using integer division

consider dividing by a float

[wintry quarry]

well if num is a double (which it is) that won't be integer division

but... really... this needs to be debugged step by step

[ivory bobcat]

Always log when you're not sure and never assume what the issue is without debugging first.

[grizzled island]

to keep two decimal

[polar acorn]

Oh, you're right. I always just assumed both operands needed to be floats or doubles or else it'd use int division, but I just checked it and it works. Guess I've been doing an extra cast a bunch of times when I didn't need to

[zenith cypress]

math.floor also doesn't have an int overload, so it will be a float by default

[wintry quarry]

it has a double overload!

[shell herald]

i have this script for dynamic footsteps. the terrain splatmap detection works great. it is not only supposed to work with terrain but also normal gameobjects. the weird thing is, that it "prefers" the terrain. it plays the terrain sound even if a gameobject with the right layername and collider is what the player is standing on. it only works when the terrain is no longer in raycast distance and i have no idea why

https://hastebin.com/share/wecajecole.csharp

[signal mango]

There is no guarantee on the order of the array you get from RaycastAll/RaycastNonAlloc iirc

You have to sort it yourself if you want to treat [0] as the closest

[shell herald]

and how would i do that?

[signal mango]

Yep, straight from the docs:

[grave furnace]

hi guys im making a pong but both players move at the same time lmao https://dotnetfiddle.net/CrVh9g

(is that how you share your code on this site?)

[signal mango]

You can use Array.Sort:

Array.Sort(hits, (a, b) => a.distance.CompareTo(b.distance));

[polar acorn]

That's more of a website for running C# code to see what it does. There's better websites for sharing !code, but this one works for that purpose I suppose

Friends, I'm sorry, I'm a beginner, please don't judge me. Could you please tell me why what I want to do isn't working? I created a class CarMovementService which is responsible for the calculations to be applied to the car, meaning in the main script CarLogic. Why isn't the car moving? I have a hypothesis: it might be related to the data being sent and not returned, or the rb2d is being passed as a copy and not a reference. Please help, I'm stuck.

can't i insert my physcs material o my rigidbody2d?

[polar acorn]

Well, let's start with the super simple things first to try to eliminate any easy solutions:
Is inputMovement getting set by anything? It looks like you've got some functions that are presumably being called by some outside input handling component, but I don't know if they're actually getting called. Try logging it in FixedUpdate, and see if the value changes as you input your movement
