hello, i was trying to implement a death screen into my game - however when the scene resets and the player reloads their gun i get this error. any ideas?

[mint remnant]

Handling stack sizes was complex, someone suggested I chould use scriptable objects too. I have the whole thing working now, but it's fragile and a nightmare to debug, so it will probably get a re-design before done

Scene loads destroy objects, you can set them to not destroy on scene load but I forget the method off hand

[raw robin]

When the scene reloads, stop the game with the pause button, change your inspector to debug mode and see if any reference is empty

My guess is the gun is not referenced to the player after reset

[polar acorn]

Seems you have a script that still has a reference to the old Gun from the previous scene. That object no longer exists

[raw robin]

You're right, I misread that lol

[crimson saffron]

how would i use the notdestroyonload function? sorry if this sounds dumb i only started a couple weeks ago 😅

[polar acorn]

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html
This makes an object persist between scenes. It's probably not what you want actually, and your error likely stems from something that does have DDOL already holding on to references from the previous scene. I think more likely what you want is to have that script re-acquire references when the scene changes:

https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-sceneLoaded.html

[crimson saffron]

ok, thanks

[stark summit]

How do I make is so that the box I put code in is in c# on discord? I completely forgot

I'm trying to get gravity to work properly while falling, when it jumps and falls it has the correct amount, however whenever you simply walk off a platform, you fall very quickly much more than if you jumped

my jump just adds a force with moveDirection.y = jumpForce, but im wondering if theres a better way, since in order for it to be responsive, i set the gravity and jump force higher

[steep rose]

reset Y velocity while on ground

[indigo mirage]

private void ApplyFinalMovements()
    {
        if(!characterController.isGrounded)
        {
            moveDirection.y -= gravity * Time.deltaTime;
        }
        if(willSlideOnSlopes && isSliding)
        {
            moveDirection += new Vector3(hitPointNormal.x, -hitPointNormal.y, hitPointNormal.z) * slopeSpeed;
        }

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

i realized that the moveDirection.Y glitches out on slopes and spheres

but im not sure how to rememdy that

[steep rose]

glitches in what way

keep in mind character controllers have slopes built in

[indigo mirage]

normally on a flat surface the move direction will be around -8 to -10, but after sliding down a sphere its all the way to -150

[steep rose]

so you dont need to make them

[indigo mirage]

well this is so you arent able to just jump on top of them

because the normal character controller allows you to jump over them

[steep rose]

🤔

[indigo mirage]

this makes it so you slide down and cant go up something you shouldnt

[steep rose]

just move the character controller by Vector3.down via move method and you should be good

if you detect you are on a steep slope ofc

[indigo mirage]

still in moveDirection?

[steep rose]

you probably coud just make another move method and if on a steep slope move the character controller down

it should slide down

as long as you dont translate it

using translate will ignore collisions

[indigo mirage]

wouldnt this stop the character from moving in any direction while sliding

[steep rose]

do you want to move while sliding down?

[indigo mirage]

one moment let me get a short video of what it does currently

note the moveDirection in the bottom right

how to goes up to insane values

[indigo mirage]

this is with above code

[steep rose]

then reset the Y movedirection while grounded

once off steep slope

reset it

[indigo mirage]

that fixes the amount

however now I am able to jump over the slopes, because it resets the value while on the slope

[steep rose]

when off steep slope

you need to check if you are on a steep slope

if not then reset it

[indigo mirage]

oh I see what you mean

hmm it still seems to think im on the ground even when on the slope

[steep rose]

are you checking the slope angle?

[indigo mirage]

Ohh wait i see what I did wrong

i think it was a mistype, let me test it

Ok this works, i think the only thing I need to figure out now, is that if the slope goes right over an edge

because the -y movedirection will still rack up, but there wont be any ground to reset it

[steep rose]

you can reset it while in air but you need to make gravity seperate then

or else you wont have gravity

[indigo mirage]

Alright, well thanks for you help

I appreciate it

[steep rose]

👍

come back anytime for help

[indigo mirage]

actually, (im sure this is just me being dumb) do you know why this ramp lets me stand at the very bottom?

its probably something to do with my isSliding bool...

    private bool isSliding
    {
        get
        {
            if(characterController.isGrounded && Physics.Raycast(transform.position, Vector3.down, out RaycastHit slopeHit, 2f))
            {
                hitPointNormal = slopeHit.normal;
                return Vector3.Angle(hitPointNormal, Vector3.up) > characterController.slopeLimit;
            }
            else
            {
                return false;
            }
        }
    }

[eternal needle]

Add debugs to see why specifically. First thing I'd check is the angle
Also something like this shouldnt be a property imo. Just check every update or fixed update. If you use isSliding twice in a frame then it's doing unnecessary work

[indigo mirage]

Ah, I see what you mean about the unnecessary work, thats simple enough, as for the debugs, it seems that its not detecting anything, which is causing me to believe that because the raycast comes out from the center, at the very edge the hitbox is still on the slope, but the center is over the edge, im not sure how to fix that without an obscene amount of raycasts on all sides

[steep rose]

its because you are using the built in charactercontroller.isgrounded I believe it detects the ground via the collider hit points

i could be wrong

so its detecting you are on ground but not on a slope

[indigo mirage]

the raycast IS running, its just not hitting anything

yes

[main karma]

so I managed to solve the issue by removing deltaTime all together

void CheckDeceleration(ref Vector3 moveDir3D, Vector2 inputVector)
    {   
        moveDirDecel.x = moveDir3D.x /6;
        moveDirDecel.z = moveDir3D.z /6;

        if (gravity_Check)
        {
            moveDir3D += ((inputVector.y * transform.forward) + (-inputVector.x * transform.right)) * 2 - moveDirDecel;
        }
        else
        {
            moveDir3D += ((inputVector.y * transform.forward) + (inputVector.x * transform.right)) * 2 - moveDirDecel;
        }
        
        Debug.Log(moveDir3D);
       
    }

works somehow like a charm

[steep rose]

then yes its most likely the charactercontroller.isgrounded detecting ground but your raycast isnt hitting anything. to fix this you can either make your own isgrounded system (really easy) or just make multiple raycasts to see if you are on a slope or not

or just orient your raycast to the slope

[meager sinew]

These are in 2 different scripts
and i keep getting NullReferenceException: Object reference not set to an instance of an object
how do i fix it?

[rocky canyon]

set an instance of the object to the reference

[indigo mirage]

is making your own isgrounded that simple? because just thinking about it i feel like the multiple raycases would be easier

[steep rose]

its 1 line of code

[rocky canyon]

double click the error.. find out what line causes the error...

[languid spire]

you'll need to post the full error

[steep rose]

depending on what you want

[rocky canyon]

check the references within that line

• one of em is not assigned

• figure out a way to assign it

[meager sinew]

Line 16 in the OnCollisionEnter 2D

[indigo mirage]

oh? is it just copying from the inbuilt is grounded, or is another raycast?

[steep rose]

if you want a raycast system then do that, if you want a checksphere system then you can do that both are easy

[rocky canyon]

well since u cropped the line numbers that information is only useful to you

[meager sinew]

This what you need? im not sure

[rocky canyon]

we still dont know what line 16 is..

[steep rose]

give us the full !code

oh its not in the screenshot lol

[steep rose]

preferably in a paste site

[meager sinew]

oh

[rocky canyon]

its _gameUIHandler

[rocky canyon]

btw.. even w/o u posting the code

you have a private reference.. and no logic that assigns it

since its private i know its not assigned in the inspector.. so how is Unity supposed to know what instance of it, you are trying to use

you either need to

private void Awake(){
   _gameUIHandler = some sort of logic to assign one;
}```
or use
`[SerializeField] private GameUIHandler _gameUIHandler;`
so you can assign it via the inspector

[indigo mirage]

So im trying to use checksphere to replace isGrounded, and have this:

(Physics.CheckSphere(characterController.transform.position, characterController.radius, 10)

i know that the character controller position will have to be moved downward to the feet, but does everything else seem correct

[meager sinew]

public class CharacterManager : MonoBehaviour
{
    [SerializeField] public int _playerHealth = 8;

    private GameUIHandler _gameUIHandler;

    public void OnCollisionEnter2D(Collision2D other)
    {
        if (other.gameObject.CompareTag("Enemy"))
        {
            _playerHealth--;
            _gameUIHandler.ChangeHealthBarSprite();
        }
    }
}
public class GameUIHandler : MonoBehaviour
{
    [SerializeField] private Sprite[] _healthBarSprites;
    private Sprite _currentHealthBarSprite;

    private CharacterManager _characterManager;
    private int _playerHealth;



    #region HealthBar Sprite
    public void ChangeHealthBarSprite()
    {
        _playerHealth = _characterManager._playerHealth;

        for (int i = 0; i < _healthBarSprites.Length; i++)
        {
            if (i == _playerHealth)
            {
                _currentHealthBarSprite = _healthBarSprites[i];
                gameObject.GetComponent<SpriteRenderer>().sprite = _currentHealthBarSprite;
            }
        }
    }
    #endregion

oh i figured out how to post code lol

[rocky canyon]

yea, the solution has already been provided tho..

little too late

[meager sinew]

ik

[steep rose]

you can just use a seperate gameobject instead of the character controller position

you probably would want a seperate float as well for the radius of the sphere

[indigo mirage]

wouldnt I want the radius to be the same as the character controller, to see if it is the one touching anything?

[steep rose]

you would get the same issue

if it was the same

so just make it a bit smaller

[rocky canyon]

yea, you can just use an offset..

public Vector3 offsetForFeet = new Vector3(0,-1f,0);

(Physics.CheckSphere((characterController.transform.position + offsetForFeet), characterController.radius, 10)

or do as dec, sed and just use a different gameobject or something..

public Transform feetLocation;

[meager sinew]

i did the serialized field and all i can assign to it is the script and i still get the error

[rocky canyon]

you dont assign a script to it..
you assign a Gameobject, within the scene, that has that script attached

[meager sinew]

ye thats what i ment

still got error

[rocky canyon]

whats the error say now?

if ur still getting an error that means theres another null reference error somewhere

its probably this one now

[meager sinew]

its the _playerHealth = _characterManager._playerHealth

[rocky canyon]

ahh okay..

well gotta assign _characterManager then

[meager sinew]

oh ye

[rocky canyon]

things like floats, ints, vectors and stuff.. don't need assigned b/c they have default values

[terse spindle]

hey spawn camp

[rocky canyon]

but if ur using custom scripts and stuff

they always have to be told what instance of it ur using

[meager sinew]

oh ok

[rocky canyon]

or create a new one on the fly

[meager sinew]

so can i assign it in the inspector?

[rocky canyon]

u can put [SerializeField] in front and yea

then assign it

^ thats the go to way of assigning things quickly

it doesn't always work.. for things like prefabs.. u cant assign stuff in the scene until they get spawned

soo u have to do things like GetComponent or Find.. or something lik ethat in the Awake() / Start() fuctions

[meager sinew]

oh ok

[rocky canyon]

but for things u can. assign them in the inspector

[meager sinew]

ty

error is gone

[terse spindle]

do anyone got active ragdoll tutorial that you can recommend to me

how far up should I put the empty object? because I dont want it to touch the ground before my charachter controlelr does

[steep rose]

just at the bottom of the character

[rocky canyon]

make the Z coord 0 for the love of all thats precious

[steep rose]

you adjust the variables in the inspector to get the desired effect you want

not the position

[indigo mirage]

with zero its all the way over here

[rocky canyon]

why?!

is ur player offset?

[indigo mirage]

my camera probably

its in the front of the player

[rocky canyon]

do u have it set to pivot?

[steep rose]

just put it in the bottom middle of your character

[indigo mirage]

considering I dont even know what that means, no

[steep rose]

it doesnt need to be centered (to much)

[rocky canyon]

pivot shows u the origin of the object u've got selected...

[indigo mirage]

oh yeah, its on pivot

[rocky canyon]

if its set to center it shows the general center of all objects

ya, somethings not lined up correctly lol

[indigo mirage]

heres on center and pivot

[steep rose]

oh my

[rocky canyon]

ohhh yae...

thats gnarly

[steep rose]

lol

not that offset

[rocky canyon]

when u go to rotate stuff around its gonna break all to heck

[steep rose]

lmao

[indigo mirage]

oh boy

[rocky canyon]

show ur heirarchy

and the inspector

[rocky canyon]

okay.. so far soo good.. b/c the position of the ROOT object doesnt really matter

[steep rose]

zero them out

[rocky canyon]

the main camera tho.. lets see it..

it should be 0, (some number), 0

[steep rose]

then adjust via Y

only the children though

[rocky canyon]

wait no

[steep rose]

not the parent

[rocky canyon]

why why.. is the center of this guy all jacked up?

[indigo mirage]

heres everything(children) zeroed

[rocky canyon]

ya, i didnt see ur Player Capsule...

[steep rose]

change the center on the character controller to 0,something,0

[rocky canyon]

its center should be 0,something,0

[indigo mirage]

ohhh, my bad i misunderstood

[rocky canyon]

we did too

ur all good..

[rocky canyon]

ur camera probably is right then

yes... thank you!!!

[steep rose]

very nice

clean

[rocky canyon]

u were giving me anxiety

[steep rose]

calm

and collected

[rocky canyon]

NOW back to the foot at hand

lol

[indigo mirage]

lol

[rocky canyon]

yea ur ground check should be just below the capsule

[steep rose]

if you want to use they raycast method you can if needed

[rocky canyon]

if u want to raycast from that position it should be a little above the edge

[indigo mirage]

Might as well learn the check sphere while im here

[rocky canyon]

something like that

[steep rose]

well you did everything correct but is the 10 a layer?

dang

i didnt reply

[indigo mirage]

10 is the layer for all my ground objects

[steep rose]

then you are fine

[indigo mirage]

rq how do you get the highlight of the char controller, and still able to move just the empty object

i have to unhighlight the controller whenever i want to move it

[steep rose]

his character controller is on his parent object

and hes moving the parent

[indigo mirage]

oh I see

[steep rose]

he has a capsule to tell him where is player is

which is preferred

[rocky canyon]

yea, i use a capsule mesh renderer for my Graphics object

just make a capsule 3d object and remove the collider from it.

[steep rose]

its pretty much a standard

[rocky canyon]

(the CC already has a collider within it)

really helps when writting ur controller code..

so u dont have to keep clicking and seeing the gizmos

[indigo mirage]

Ah i see, no collider in the graphics

[rocky canyon]

just make sure its lined up to the controller's collider

[rocky canyon]

nope.. just a renderer and a filter..

so i just created a 3D > Capsule and removed hte collider

[indigo mirage]

cool

[steep rose]

if you had a collider on the graphics then it would most likely fly in the air

which is not preferred

[rocky canyon]

it would spaz out

and get all jittery and stuff.. it'd break my gun raycast, my groundcheck raycast, and alot of other stuff

[indigo mirage]

my char controller is not a perfect capsule

[steep rose]

thats fine

[indigo mirage]

how do you change the radius of the graphics capsule

[steep rose]

just from the inspector

[rocky canyon]

collider inception

[rocky canyon]

u can scale it using the transform

[steep rose]

via transform

[rocky canyon]

(since its just graphics)

[indigo mirage]

oh im just being dumb, i was expecting a radius option but that makes sense

[rocky canyon]

.25, some height, .25

[rocky canyon]

the general rule is to keep the Root object scaled to 1,1,1 .. and anything physics... most people make the graphics as a child object..

that way u can scale it any way u want.. and it wont affect ur physics/ code

• Main GameObject (the root) [1,1,1]
  • Graphics [anything you want]

i said scaled to 0.. but then it wouldnt exist 🤣 i meant scaled to 1

[indigo mirage]

sorry i may be confused but that breaks everything at 0,0,0?

ohh yeah its alright

[rocky canyon]

yea.. sorry

lol

[indigo mirage]

one final thing, its not quite matching up

[rocky canyon]

its fine... w/ that weird tall shape it wont exactly

[indigo mirage]

ok

NOW, finally on to the actual issue

[rocky canyon]

yessir!

[steep rose]

this is what mine is set up as

i have zero clue why i have 2 groundchecks but oh well

[wintry quarry]

Well we have no way of knowing what this is doing without further context

[rocky canyon]

just two ??

lol.. j/k 🤣

[wintry quarry]

Like where it's being called from and how the move3d vector is used

[mental coral]

Hello Anyone know how can i fix this error

[steep rose]

thats insanity

pure insanity 😂

[summer stump]

You don't use Console in unity

[rocky canyon]

accuracy * 50

[steep rose]

thats true

lmao

[rocky canyon]

i typically use 7...

[mental coral]

I am just learning C# basics its not opened in unity

[rocky canyon]

gives good detection w/o being too expensive

[summer stump]

Ah, then go to the !cs server

alright

[rocky canyon]

sorry Aethenosity wrong ping

[steep rose]

yeah, i have never explored with the dynamic ground array stuff

i have never been good with arrays

they scare me

[summer stump]

I was confused haha. No prob

[rocky canyon]

arrays are sooo ez dec

[steep rose]

bet

[rocky canyon]

u should def look into them when u got some free time

👍

[steep rose]

i probably will, i know a lot of times where an array would come in handy

[rocky canyon]

just used one, and a forloop to draw a gizmo circle

altho.. i can probably do that w/o the array.. and just add to the values in the loop

but loops scare me

[fading mountain]

Hey guys. I'm trying to set up input with the new input system. In my input actions file/window, there is no option for the spacebar, or any other keyboard inputs. Specifically how do I set up the spacebar for my game?
This video shows that the input actions doesn't even listen for the keyboard and also that I can't type it in. Maybe im typing it wrong though.

[rocky canyon]

press the Listen button

and then press a key and see what happens

[steep rose]

thats the input system?

what even is that

i must be under a rock or something

[fading mountain]

nothing from the keyboard

[rocky canyon]

weird

[rocky canyon]

you should def have a Keyboard dropdown in there

[steep rose]

the keyboard/mouse bool isnt enabled

enable it

[rocky canyon]

lol look at u.. problem solving things u never even heard of

[steep rose]

still i have never seen the new input system

bro im serious

[rocky canyon]

ya, get out from under ur rock

[steep rose]

i havent seen it before lmao

[fading mountain]

no I did try that and it didnt work

tried it again right now, thats not wat its for

[rocky canyon]

its basically a must-have if u want to do things like Dynamic Key-binds

for the menu's

or 2 player games or w/e

[iron steeple]

Does ontriggerenter effect still works if both object istrigger is enabled

[indigo mirage]

So now the sliding isnt working at all, its not detecting that its on a slope at all
heres the check sphere

Physics.CheckSphere(groundCheck.transform.position, characterController.radius  - 0.05f, 10)

[steep rose]

i would make the radius a float

and adjust it from there

[steep rose]

also isgrounded = Physics.CheckSphere(groundCheck.transform.position, Float, 10)

[indigo mirage]

well right now I just have the whole checksphere in place of where isGrounded normally goes

while testing

[iron steeple]

It doesnt work?

I tried it it doesnt work

[steep rose]

still use a float

[indigo mirage]

on it boss

[rocky canyon]

you cant use Keyboard for the setup u have

Value Vector2

My Axis-Type Keybinds are under an action using 2D Vector DigitalNormalized

[steep rose]

the new system is 🤔

this is gonna take a lot of time to learn it

[fading mountain]

let me try that. I was just about to delete my project and start again

ty

[indigo mirage]

So i tried setting the groundCheckRadius to 0.1,0.2,...0.6 and it didnt detect at all in any

Physics.CheckSphere(groundCheck.transform.position, groundCheckRadius, 10)

[steep rose]

its probably gonna be 2.3 or 3.2

[rocky canyon]

its not too bad.. u can set up action maps and stuff.. and then it Generates a C# file for you.. with all the Callbacks and stuff it needs

[indigo mirage]

wouldnt that go past the radius of the char controller though?

[rocky canyon]

its basically Events being called when stuff happens (instead of polling [every frame in update]) for example

[steep rose]

from what i tried it doesnt

but 0.6 and 0.2 is very small

just adjust it till you get a hit

[indigo mirage]

tried all ints from 2-10 none are sliding

[steep rose]

seems interesting

[steep rose]

is it detecting ground?

[indigo mirage]

nope

[steep rose]

layering wrong?

[fading mountain]

@rocky canyon you fixed by issue tysm. works like a charm

[indigo mirage]

shouldnt be, its 10 in check sphere and the ramp is on layer ten

[summer stump]

Yes
The Three Commandments of OnTriggerEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt tick isTrigger on at least one of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

(Stolen from digiholic)

[steep rose]

try changing the 10 to a layermask

and do what spawn said

[indigo mirage]

layermasks look like this correct?:
layerMask:10

never used them before

also what did spawn say, that was with the raycasts instead of checksphere?

[summer stump]

No, a layermask would not look like that at all

I recommend just making a layermask variable and changing it in the inspector btw. That is the easiest.

Otherwise if you want layer 10, it would be 1 << 10
You need to use a bitwise operation

A bitmask (layermask) is like a list of bits. Each a flag

[rocky canyon]

    private void OnDrawGizmos()
    {
            // Set the color for the Gizmo
            Gizmos.color = Color.yellow;
            // Draw a wire sphere with the radius specified by groundCheckRadius
            Gizmos.DrawWireSphere(groundCheck.transform.position, groundCheckRadius);
    }
``` i said u can use OnDrawGizmo's to help u visualize

[pallid nymph]

to be fair, it might, if it's layers 1 and 3 😄

[steep rose]

public LayerMask layer

Physics.CheckSphere(groundCheck.transform.position, Float, layer)

or do what Aethenosity said

[indigo mirage]

OK perfect, its sliding now,

[steep rose]

also preferrably a [seriliazed] private layermask

[indigo mirage]

yeah i did a serialized private layermask

yep

[rocky canyon]

cool! :).. i actually didn't know if it would or not... I just have it setup from a long time ago.. and i just copy and paste it around to create new ones

[indigo mirage]

however it still has the same issue with isGrounded :/ im stuck at the edge of the ramp

[summer stump]

That would be layer 2. It would only be one layer, as there is only one bit set to 1

[steep rose]

lower it till you fall off

[indigo mirage]

its at 0.1575 right now

and im sliding but not falling off

[steep rose]

okay

[pallid nymph]

they do start at 0, yes... and 10 is 2 layers 1010... but anyway, was just jokingly being too pedantic 😛

[indigo mirage]

any lower and it doesnt slide at all

[steep rose]

what does the ramp collider look like

and do what spawn said

[steep rose]

collider

and visuallize the sphere

using what spawn suggested

[indigo mirage]

ok one minute

[steep rose]

here (sorry for the ping)

[summer stump]

Oh wait

I see what you mean now. Yes I get it. My bad
It would "convert" it to what you said

[rocky canyon]

and you don't need to Call OnDrawGizmos() from update or anything..
its one of those magic unity methods.. that just work on its own

[indigo mirage]

yeah its doing that rightnow and my console is overflowing with errors lol

but it still shows it

[rocky canyon]

sooo its in the right location it seems

[sleek gazelle]

'Default parameter value for 'rotation' must be a compile-time constant'

    private void SpawnObject(GameObject obj, Vector3 pos, float scale = 1, Quaternion rotation = Quaternion.identity){

How can I fix that please?

[summer stump]

Set it in Awake or Start

[rocky canyon]

try = Default

u shouldnt name it rotation btw

[cosmic dagger]

where do you assign it? that's the issue . . .

[sleek gazelle]

As a methoed parameter default value

[rocky canyon]

call it myRotation or summin

[zenith cypress]

.identity is a property, you cannot use it as a method param default value

[main karma]

did you guys know that if you call deltaTime in fixedUpdate, it calls fixedDeltaTime instead?

[cosmic dagger]

as spawn mentioned, it needs to be default as it's a property, not a constant . . .

[summer stump]

Yep. Pretty common knowledge around here

[rocky canyon]

i just had the same error w/ Vector3

default worked in my case

[sleek gazelle]

Ok thanks, but so how do I set the rotation default value to 0,0,0?

[summer stump]

#💻┃code-beginner message

[main karma]

well it took me 3 hours to figure that out actually, was breaking a mechanic in my game

[sleek gazelle]

Ok thanks

[cosmic dagger]

yup, that's how it works . . .

[zenith cypress]

void SpawnObject(GameObject obj, Vector3 pos, float scale = 1) => SpawnObject(obj, pos, Quaterion.identity, scale);

void SpawnObject(GameObject obj, Vector3 pos, Quaternion rotation, float scale = 1) {}

A default quaternion is invalid

[rocky canyon]

🪄 wooOOoOooo

[main karma]

imo it should just call for the one I'm interested in

[summer stump]

Probably wouldn't be the first place you would look for your issue, but the docs do explicitly say that for deltaTime
https://docs.unity3d.com/ScriptReference/Time-deltaTime.html

[summer stump]

What does this mean?

[cosmic dagger]

how so?

[main karma]

well I figured it out through trial and error eventually

[sleek gazelle]

It looks like it's valid cause I just did Quaternion rotation = default and now it works fine

thanks anyway

[zenith cypress]

A default quaternion is not valid.

[rocky canyon]

i think he means if he calls time.deltaTime in fixed.. he still wants time.deltaTime.. not fixedDeltaTime

[summer stump]

But did you USE it? That is the issue nomnom is talking about

[rocky canyon]

but idk ¯_(ツ)_/¯

[sleek gazelle]

Yes

[summer stump]

Why? That would be awful

[rocky canyon]

lol.. ik im just guessing thats what he means tho

[summer stump]

In instantiate or something? Not as the parameter

[sleek gazelle]

Yes

Ah

No

You're right, I didn't use it lol

[rocky canyon]

thats b/c u assigned it lol..

but if u don't not sure what default would throw

[cosmic dagger]

that's a bit weird, but you can store deltaTime in a variable and use that variable in FixedUpdate . . .

[zenith cypress]

just have an overload that will assign it for you

[rocky canyon]

aye ^

two methods that work.. is better than 1 that doesn't i guess

[sleek gazelle]

    [SerializeField] RenderTextureMakerCamera renderTextureMakerCamera;
    [SerializeField] new Renderer renderer;

    void Start(){
        PrefabsReferences prefabsReferences = WorldManager.instance.worldsPrefabsReferences[renderTextureMakerCamera.id];
        renderer.materials[0].color = prefabsReferences.planeColor;
        SpawnObject(prefabsReferences.tree, new Vector3(0f,0f,0.3f), 0.025f);
    }

    private void SpawnObject(GameObject obj, Vector3 pos, float scale = 1, Quaternion rotation = default){
        GameObject prefab = Instantiate(obj, pos, rotation);
        prefab.transform.SetParent(this.transform, false);
        prefab.transform.localScale = new Vector3(scale,scale,scale);
    }

This is my code

and it worked fine

And I did use the quaternion defualt to set the rotation of the prefab in Instantiate()

[rocky canyon]

soo if u exclude rotation in ur method params it spawns it at Quaternion.Identity?

today, im learnin!

[sleek gazelle]

Not anymore, as this wasn't working and was throwing errors, now it's set to default

[main karma]

so basically I got a cube that pushes my player away, the player movement is in update and it decelerates over time
but the raycast that detects if the player collided happens in fixed update.
My player accelerates faster with more FPS, but also decelerates faster and so it keeps a constant speed across all framerates
But I had to divide the speed that the cube uses to push my player away using Time.DeltaTime because the deceleration speed of faster framerates is bigger and so the value of acceleration it gives must be bigger just like in movement.

And so took me 3 hours to figure out that the reason it wasn't working was because physics use fixedDeltaUpdate and so it converted it to that. In the end I just stored the actual deltaUpdate in a variable and applied it there and now it works

[indigo mirage]

its weird, its like its randomly deciding to stop at the edge

[rocky canyon]

theres not a collider on ur empty foot object is there??

[indigo mirage]

nope

[main karma]

like if I can specify fixedDeltaUpdate and deltaUpdate at the same time, it should just call for the one I want, not the one it thinks I want

[rocky canyon]

its probably just not enough force to push u up that steep of a slope

i'd see what happens on a shallower slope

[indigo mirage]

OHHH WAIT

I'm stupid

[steep rose]

actually its because you are using a raycast to detect if you are on a steep slope

[indigo mirage]

yep

tahts what i just realized

[rocky canyon]

ahhh

[summer stump]

But if you are using FixedUpdate, then deltaTime would be irrelevant and should definitely not be used

[steep rose]

best use a sphere raycast

[indigo mirage]

is there a way to get the info like a raycast hit, from a sphere check

well there it is

[steep rose]

for this aplication

[rocky canyon]

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

[indigo mirage]

thank you

[steep rose]

spherecast at the rescue

again

[indigo mirage]

lol

[main karma]

well I want to detect player collision in fixedUpdate to detect it only once and apply speed in Update basically, but I use the function that applies speed in the detection function

[zenith cypress]

Hm I wonder if instantiate does an invalid quaternion check then in C++ land before using it 🤔

[rocky canyon]

you should find out and let us know

[sleek gazelle]

Is there a channel for questions about textures rendering issues? Cause I can't find one

[rocky canyon]

#🔀┃art-asset-workflow

[zenith cypress]

Sir I do not have source code access

[sleek gazelle]

Ok thanks

[rocky canyon]

ohh thats right

[zenith cypress]

Gotta have the big bucks for that

[summer stump]

1. why apply speed in update. FixedUpdate would be better for that
2. what does that have to do with deltaTime. Use a bool to only detect once

[rocky canyon]

i was waiting for someones response

[steep rose]

🤔

[main karma]

ok so once I detect collision, I call for a function that calculates the speed and gives it back to the player.
The problem is that I call the function from from the collision detection function that happens in fixedUpdate
My player runs physics in Update and that's because when I tried making it move in fixed update it was very laggy for some reason and I gave up. And now I got so much code built up upon it that I'd rather work around it instead

I need delta time in fixed update to account for the player moving in update

so I just created a variable that stores it locally instead

[zenith cypress]

It wasn't laggy in fixed update, you just saw it without any interpolation

[main karma]

I don't even know what that means

[rocky canyon]

interpolation.. it guesses the inbetweens and gives u a smooth render

[zenith cypress]

Fixed update runs on a fixed interval, you saw it only on that interval, instead of smoothed out

[main karma]

ah I see

[zenith cypress]

You can see this if you add a rigidbody to a cube with interpolation disabled, see how it stutters, then enable interpolation, and it is smooth

[main karma]

can you enable interpolation for the default character controller?

[zenith cypress]

Nah that doesn't use physics itself

[rocky canyon]

an example

[main karma]

well I use the character controller for the player movement

[main karma]

yes I understand what you mean, thank you

[rocky canyon]

np, i just like filling up my hd w/ video 😅

[zenith cypress]

CC is fine in Update since it is a kinematic body (aka not on the physics tick). I've done checks in Fixed to then use in Update for various things, but update is fine for a CC.

[rocky canyon]

tbh, im amazed w/ myself.. how was able to get that little tilt when i go back and forth

[summer stump]

If you are using the CC, why use FixedUpdate?
Why not use OnCharacterCollideraHit or OnTriggerEnter for collisions

[main karma]

I got like 200gb of unity tutorials downloaded for no reason at all

[rocky canyon]

👀 im better than i thought i was

[rocky canyon]

for when the internet dies ofc

[main karma]

because I run raycasts to detect collision

[summer stump]

Yes? Those should be in update

[main karma]

what

[zenith cypress]

or vice versa

[main karma]

but when I run them in update they happen like 2-3 times per frame

[summer stump]

So what?

[main karma]

I only need them once

[rocky canyon]

wait... he said he using CC right?

im lost now

[summer stump]

That makes no sense

Then do a bool to only do them once. In update

[steep rose]

remind me what does CC mean

[summer stump]

CharacterController

[polar acorn]

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

[steep rose]

ah

[rocky canyon]

CC / RB carrot cake, and red balloons

[steep rose]

i guess i didnt know the abreiviation lmao

Cruise Control

[rocky canyon]

why is there fixed update being used again?

[zenith cypress]

If you want checks that are from physics, and you don't want to over-check them, you can always just check them in Fixed, save to a variable, then read from Update to check/reset it.

Or just keep them in Update. Whatever works for what you want/need.

[steep rose]

thanks digi

[summer stump]

No idea. I say it should not be at all here

[main karma]

basically when my player hits a wall that has a script, it runs the script only once and that's about it.
I used fixed update because for some reason it ran it like 3 times in update

[rocky canyon]

if ur relying on CC it has its own collisions 🤔

[summer stump]

Well yeah, update runs a bunch. Make a bool to only care about it once

[rocky canyon]

and if ur raycasting you can do that in update.. as well as fixed

i gotcha

[main karma]

how would you check if a frame as passed with a bool?

[rocky canyon]

lol.. the next time it runs

but.. u could use a timer/ or a coroutine/ or a custom tick rate.. to control how often things happen..
or throw it in fixed update.. lol

[steep rose]

you could use a coroutine

he got to it first

[rocky canyon]

but yea.. when something happens u flick the bool...
exactly one frame will happen befor its considered again.. but then it'd be a different state.. soo 1 frame has run

[summer stump]

I think we are talking past each other. You want to not hit walls. Ok, so check every update if you are moving towards the wall. If you are hitting the wall, don't move that way. Not sure why the number of times it is called even matters. But you could set some bool when you hit the thing, and reverse it when you don't

Maybe show your code. Because your descriptions are confusing me a lot.

[rocky canyon]

ive been confused.. im still trying to put it all together

[main karma]

how do you upload large codes again?

[cosmic dagger]

the player shouldn't accelerate faster with more FPS, that is incorrect and means you're frame-dependent instead of frame-independent . . .

[amber spruce]

hey so i want to check if the gameobject is on a certain layer how can i achieve this?

[cosmic dagger]

what have you searched so far?

that's an easy google answer . . .

[rocky canyon]

maybe this can help us @summer stump
lol.. just for some context while reading the code

[amber spruce]

if(this.gameObject.layer = "enemy")

im dumb

[cosmic dagger]

okay, but have you searched that question online yet? i only ask because that's a simple google search. also, you should check what gameObject.layer returns . . .

[polar acorn]

Okay, what happens if you try that

[rocky canyon]

use CompareTag(string); sorry meant to ping @amber spruce

[amber spruce]

i forgot in this case i want to do 2 equals

[rocky canyon]

oh its a layer... 🤦‍♂️. sorry i need discord scaling

[amber spruce]

ye

[cosmic dagger]

you probably mentioned it, but how are you moving the object? it should be framerate independent and not move faster/slower depending on the FPS. using deltaTime or fixedDeltaTime shouldn't mess up anything in FixedUpdate . . .

[main karma]

ok here's the entire characterMovement code, it's not very modular, poorly written, and has a lot of other stuff as well but it works

[rocky canyon]

ohh deer

[main karma]

wait

[amber spruce]

i think i figured it out i just cant use the layer name i gotta use the number for it

[main karma]

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

[rocky canyon]

you could use a layermask.. but yea name works too

[main karma]

ok I think it works now

[rocky canyon]

the paste? yea...

holy using statements batman

[summer stump]

You are doing three separate raycasts in the check collision method....

Then omg five in the other. Ok, I guess those ones make sense. They are pointing different ways

[main karma]

well I need to check up, down, and then I also need to check if the cube is at my feet or my face in the direction that I'm walking towards

[rocky canyon]

weird code lol..

[main karma]

my first unity code

been working at it for months

[rocky canyon]

cool cool...

[mint remnant]

https://gyazo.com/d53a6bc1cdee2e467ed5dbd7180d5547
Is the order htey are loaded deterministic? or could it be random?

[rocky canyon]

sounds like my character controller..

8 months

ur player moves in update..
yet u only jump in fixed?

[main karma]

the Y direction is completely separate from the other 2

[rocky canyon]

it goes like this https://docs.unity3d.com/Manual/ExecutionOrder.html

https://docs.unity3d.com/Manual/class-MonoManager.html
and this

yes... theres no other way, esp not random

not sure else u could mean by loaded.. unless ur talking initialization type stuff

[main karma]

you should see the portal script I made, bet no 1 would understand it

[rocky canyon]

ya, spatially.. but logically id reckon they'd both be as equals

[cosmic dagger]

are you talking about the scripts in the Script Execution Order?

[rocky canyon]

if u let me move 60 times in a second during update.. but u only allow me to jump every 50.. it wouldnt feel balanced

but im just nitpicking.. its not like its broken or anything so ignor me lol

[main karma]

basically I handle gravity and jumping together, and moving with the deceleration on the other 2, I got 2 different forces that deal with how the player stops and they never intersect

[rocky canyon]

ah, makes sense.. mine i do that kinda too.. but i add all my forces up before each move frame

b/c my gravity is interpolation during the update

also w/ my grounded/slope checks

[mint remnant]

I mean like if you have script A and script B and have set nothing to override the order. It says in the order loaded, but don't see anything that states how one is loaded before the other

[rocky canyon]

that is random..unless u specify

[indigo mirage]

I updated all the isGrounded to the customIsGrounded, and im getting this weird bug when in the top corners of platforms

[rocky canyon]

thats why singletons and initializations of those can error.. unless u have one awake b4 the others or 1 start b4 the others

[main karma]

idk, it was tuff for me to figure out, especially when I had to make a script that inverts gravity

[rocky canyon]

and then you'll have a race condition.. its best to use

• Awake to initialize self
• Start to initialize/grab components or w/e from others

[main karma]

see I have the exact same issue with my game, the way I solved it was that I made the character controller SO SLIM that it's barely visible, probably not the smartest solution

[indigo mirage]

my character controller is slimmer than normal, but i wouldnt say you cant see it

[cosmic dagger]

That only applies to the scripts added in the Script Execution Order window. You are specifically on the page that talks about using the Script Execution Order settings . . .

[main karma]

well I may exaggerating

[indigo mirage]

my radius is 0.25

[main karma]

very slim nonetheless

[indigo mirage]

i see

[main karma]

I think that that's just how the character interacts with slopes edges I guess

actually I figured this late and never used it but there's a better character controller in the asset store made by unity if I'm not mistaken

for free

[indigo mirage]

whats different about it?

[main karma]

idk let me look it up again

[indigo mirage]

alr thank you

[main karma]

a lot

it has gravity, uses cinemachine

I see android joysticks on some images

ah yes those are included

[indigo mirage]

neat, but il stick with this custom 'basic' one for now, as this is just me learning unity

[main karma]

here's a link to it https://assetstore.unity.com/packages/essentials/starter-assets-character-controllers-urp-267961
if it helps with anything

[main karma]

yeah I did the same, I needed my own custom logic anyways

[indigo mirage]

wait are you unable to add custom logic to the advanced one?

or just because you already wrote it

[main karma]

well, yeah I have already written it by then, but even if I hadn't I feel like it's a lot harder to modify someone's script than it is making your own

[indigo mirage]

ofc ofc

[amber spruce]

how do i instantiate smth as a child of a specific gameobject

[slender nymph]

look at the available overloads for Instantiate

[frosty hound]

Instantiate has a parent parameter you can set. Or you can set it afterwards with .SetParent(...) on the transform of the object you've instantiated.

[flat gale]

I am making a turn based rpg and am currently stuck on an issue where the enemy I touch doesnt delete in the overworld scene after I finish a battle. Im pretty new to unity and my only thought so far has just been to destroy the enemy object when its touched by the player but when I destroy it the enemy it reapears in the overworld when the battle is over. Any ideas?

[rich adder]

you have to track the state of your enemy , if it was destroyed in battle scene it should not reappear

[rocky canyon]

looks like a problem w/ the way ur gravity is affecting the capsule + a spamming of grounded/isn't grounded

[indigo mirage]

yeah it glitches only when jumping on a platform near the very edge

[rocky canyon]

https://paste.myst.rs/rl9kfxze i was gonna say, urs looks pretty complex.. lot of that can be simplified to get the almost exact same feel.. mine uses cinemachine as well

you can check out how my flow worked atleast.. (just commenting back from when i mentioned your jump)

but if it aint broke dont fix it.. ya know.

[rocky canyon]

ya, b/c the capsule was not grounded.. then it is grounded for just a second.. and then slips off the edge, then its not grounded.. but before it call fall.. ur spherecaster says it is... and then it cycles

what happens if u made ur spherecast just a little smaller than the player

[indigo mirage]

it is by 0.01

[rocky canyon]

ah, nvm that may make it worse

ohh its that dang gizmo thats throwing me off

u should remove that if its not like that anymore

[indigo mirage]

the gizmo is the custom is grounded radius

[rocky canyon]

or comment it out // unless ur still using it

[indigo mirage]

shouldnt i be using it because this is a isgrounded issue

[rocky canyon]

when that happens i bet ur isGrounded is flickering on and off

whats ur groundcheck code look like

[indigo mirage]

one sec

[rocky canyon]

thats a crazy list of variables lol

[indigo mirage]

lol its in debug

i have a bunch of headers in normal

[rocky canyon]

still.. the white ones arent 😅

[rocky canyon]

its ur sliding logic + ur grounded logic

they arent playing well together

[indigo mirage]

private bool IsSliding
    {
        get
        {
            CustomIsGrounded = Physics.CheckSphere(groundCheck.transform.position, groundCheckRadius, groundLayerMask);
            if(CustomIsGrounded && Physics.SphereCast(transform.position, groundCheckRadius, Vector3.down, out RaycastHit slopeHit, 2f))
            {
                hitPointNormal = slopeHit.normal;
                return Vector3.Angle(hitPointNormal, Vector3.up) > characterController.slopeLimit;
            }
            else
            {
                return false;
            }
        }
    }

put the customIsGrounded in here just to show what it is

just tried to set all other customIsGroundeds back to regular charcontroller.isGrounded still didnt work

[rocky canyon]

hmm.. u could buff up ur regular ground detection...
or you could use a cooldown buffer or something to the isSliding.. soo once u start sliding you can't begin sliding for a few milliseconds or w/e.. soo that way once that isSliding starts to flicker like it does.. ud be able to override it and walk up just enough to where the next time the issliding check goes u wouldnt be sliding..
then finally.. you could use a more complex ground check.. or additional raycasts.. to check if ur up on the ledge

it looks like one of those really hard to solve unless ur right in front of it, tinkering w/ it urself.. kinda problems

[steep rose]

whats the problem? i came in a little late, did the spherecast not work?

ah

the spherecast could be hitting the wall reading 90deg and thinking its a slope

but like spawn said, you can use a cooldown to be able to slide. like

if(Wassliding){
  //some corountine to wait a certain time then allow sliding again
}

[sleek marten]

Hey, everyone! I'm having some real trouble with an array. I've tried a few things but I still end up stuck with this one issue I can't solve.

What I'm trying to do:
I have buttons set into an array. I have a reference to a counter that goes up by 1.
When the counter has a value that's equal to a button's element number, that button should change animation states.

What the problem is:
Only the first button in the array is being effected.

{
    public Button[] buttons;
    public PersistentCounter counter;

    private string currentState;

    public const string LEVEL_BUTTON_ACTIVE = "Level_Button_Active";
    public const string LEVEL_BUTTON_UNLOCKING = "Level_Button_Unlocking";
    public const string LEVEL_BUTTON_IDLE = "Level_Button_Idle";

    void Start()
    {
        CheckButtonsAgainstCounter();
    }

    public void CheckButtonsAgainstCounter()
    {
        int counterValue = counter.GetCounterAmount();

        for (int i = 0; i < buttons.Length; i++)
        {
            Animator buttonAnimator = buttons[i].GetComponent<Animator>();

            if (buttonAnimator != null)
            {
                if (i <= counterValue)
                {
                    ChangeAnimationState(buttonAnimator, LEVEL_BUTTON_UNLOCKING);
                }
            }
        }
    }
    void ChangeAnimationState(Animator animator, string newState)
    {
        // Stop the same animation from interrupting itself
        if (currentState == newState) return;

        // Play the animation
        animator.Play(newState);

        // Reassign the current state
        currentState = newState;
    }
}```

[indigo mirage]

sorry was away for a minute, this would stop my character from sliding on a normal slope im pretty sure

        if(willSlideOnSlopes && isSliding)
        {
            moveDirection += new Vector3(hitPointNormal.x, -hitPointNormal.y, hitPointNormal.z) * slopeSpeed;
        }

heres the part in my ApplyFinalMovements();

[steep rose]

it shouldnt, if you were sliding on a slope but now you are not do a cooldown

[indigo mirage]

but if its starting to slide on the corner wouldnt it continue to start to slide?

[steep rose]

no

actually now that im thinking about it, it would probably do the slide once and then act normally

not just act normally

[steep rose]

you can try it, but it might do this so

[indigo mirage]

sorry was starting to work on the coroutine, i think it would do the first slide movement then stop you on the ramp not sliding until to stalltime completes, then would do that one movement then go back to standing still

[main karma]

yeah I see what you mean

[steep rose]

you could just make the spherecast not detect 90deg angles

that would work

or an angle over your steep angle

if(angle >= 90){
 //dont slide
}

//or

if(angle >= steepslopeangle && !angle >= 90){
 //slide 
}

something like that would work

[rocky canyon]

no matter how u do it.. basically it comes down to prioritizing 1 of 2 things..

either u climb up on the ledge.. or u fall of it

i have one of each lol.. (my character controller always grabs the ledge like a champ (b/c he only has 1 raycast).. the other i paid for.. and he tends to fall off of edges.. (it uses an array of raycasts in a circle)

one has a better detector.. it can know when ur not techanically on the ledge

and it yeets u down

[rocky canyon]

ya, i agree w/ this..

i think ur slope detection shouldnt detect over soo steep an angle

[indigo mirage]

Sorry, my discord was breaking, and wasnt letting me send any messages

[rocky canyon]

like at all

[indigo mirage]

right now it just uses the character controller slope limit

Vector3.Angle(hitPointNormal, Vector3.up) > characterController.slopeLimit;

how something like this

if(!(Vector3.Angle(hitPointNormal, Vector3.up) >= 90))
                {
                    hitPointNormal = slopeHit.normal;
                    return Vector3.Angle(hitPointNormal, Vector3.up) > characterController.slopeLimit;
                }

[rocky canyon]

~~wouldnt it be something like? ~~

        for (int i = 0; i < buttons.Length; i++)
        {
            Animator buttonAnimator = buttons[i].GetComponent<Animator>();
            string buttonState = LEVEL_BUTTON_IDLE; // (OR LEVEL_BUTTON_ACTIVE)

            if (buttonAnimator != null)
            {
                if (i <= counterValue)
                {
                    buttonState = LEVEL_BUTTON_UNLOCKING;
                }

                ChangeAnimationState(buttonAnimator, buttonState);
            }```

so u can keep all the buttons idle except for the one ur changing? edit: nvm, misread the problem

[indigo mirage]

So i added a debug variable to show me what the angle in, and it doesnt even seem to get to 90 or 0 at all when jittering on the corner of the platform

[sleek marten]

The buttons are used for a level selector. They're supposed to change animation states sequentially based on the counter value

[rocky canyon]

ohh sequential gotcha

yea, i cant read today..

[sleek marten]

you and me both

[steep rose]

you should put Vector3.Angle(hitPointNormal, Vector3.up) > characterController.slopeLimit;
asAngle = Vector3.Angle(hitPointNormal, Vector3.up)
then return return hitPointNormal.normal != Vector3.up; for readability

this is mine

    private bool OnSlope()
    {
        if (Physics.Raycast(transform.position, Vector3.down, out Slopehit, Slopehitrange * 1.5f))
        {
            //calulates angle between vector3.up and slopehit.normal to get the angle of the slope
            angle = Vector3.Angle(Vector3.up, Slopehit.normal);
            if (angle < 40)
                slopehitrangefloat = Slopehitrange / slopediv;
            else if (angle > 40)
                slopehitrangefloat = Slopehitrange;
        }

        if (Physics.Raycast(transform.position, Vector3.down, out Slopehit, slopehitrangefloat))
        {
            //returns false if not on slope (basically means to not use slope code)
            return Slopehit.normal != Vector3.up;
        }

        return false;
    }

this is modified so ignore the extra stuff

you would only need 1 raycast

[steep rose]

and then just do what I said here

and you should be good

[fading mountain]

Hey guys. I'm making a sort of top down 2d game, and I want the player to rotate and look towards the mouse at all times. This is my code so far, and this is what it is producing. Any suggestions?
`void OnLook()
{
Vector3 screenPosition = Mouse.current.position.ReadValue();
screenPosition.z = Camera.main.ScreenToWorldPoint(transform.position).z;

    mousePos = Camera.main.ScreenToWorldPoint(screenPosition);
    mousePos.z = 0f;

    Vector3 directionVector = (mousePos - transform.position).normalized;
    float rotationDelta = Vector3.SignedAngle(Vector3.right, directionVector, Vector3.forward);
    transform.rotation = Quaternion.Euler(0f, 0f, transform.eulerAngles.z + rotationDelta);
}`

nevermind I guess the video is in 2 fps

so you guys cant see anyway

[steep rose]

try and record it again, it was working before you pressed play

[steep rose]

I guess your OBS is being weird but

[fading mountain]

let me close some programs

I have a weak pc

yeah i cant do anything more

just a performance issue

[steep rose]

you probably shouldnt use OBS if you have weak PC

[fading mountain]

whats the alternative

[steep rose]

look it up on youtube

or google

personally i use oCam

[rocky canyon]

i can't tell but could it be because its the transform.right thats pointing at the mouse and not the up

[fading mountain]

wdym the up? and I feel like that line is the issue myself

[rocky canyon]

u see how the right (the red axis points at the mouse) even tho i want the transform.up (axis) to point at the mouse.

[fading mountain]

updated video (ty dec_ves)

[rocky canyon]

ur calculating from vector3.right to the mouse position

but u keep adding that to the rotation each time..

(thats why it keeps spinning around in one direction)

do transform.rotation = Quaternion.Euler(0f, 0f, rotationDelta); instead (i think)

[slender nymph]

just FYI, the atan2 call and stuff is unnecessary. you can just assign the transform.up or transform.right to the direction from the object to the mouse's world position

[rocky canyon]

ahh yes, changing it now

lol, i always forget thats the easiest way

[fading mountain]

update, looks like it's working now but inverted.

[deft grail]

bro what are you using to record 😭 🤣

get OBS or geforce experience or windows recording

[fading mountain]

I have OBS but it lags too much. That software works fine

[deft grail]

literally has ads on it 💀 but alright, everyone chooses what they want i guess

[ionic zephyr]

if an object like a tree has an "object" script attached to it and I am creating a procedural dungeon, should that be a prefab or part of a tilmap?? Maybe its a stupid question but I am confused

[deft grail]

should what be a prefab, the tree? yeah

usually anything that you will use more than once / in other scenes can be a Prefab

[ionic zephyr]

it has the "breakable" logic on it

[ionic zephyr]

okay, thanks, I´ve got another question then, how could it be instantiated if the map is procedural and randomly generated?

[deft grail]

i assume the code for that would have a place where you would instantiate it
not sure how procedural works exactly though

[fading mountain]

how do I do that?

[ionic zephyr]

just randomly created terrain but I would like to know how to instantiate those trees once the map is created

[rocky canyon]

aye, did it w/o atan2.. (took me a minute.. as i forgot about the camera's Z position mattered)..

    void Update()
    {
        Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        mousePosition.z = transform.position.z;
        Vector3 direction = mousePosition - transform.position;
        transform.up = direction.normalized;
    }```

[slender nymph]

exactly like i said. use the direction as either the transform.up or transform.right depending on the direction the object faces at 0 rotation.

[fading mountain]

it's inverted though

[cosmic dagger]

then . . . switch it . . .

[slender nymph]

if you used that code that spawn just gave you and it is facing the opposite direction, then your object points down when not rotated which is not ideal. but you can just negate the direction

[rocky canyon]

can u fix the rotation in sprite editor? like u can change a pivot?

doubtful nvm

[fading mountain]

No i think that the rotation is being applied inverted. not the sprite

that's what I meant to say

[slender nymph]

what direction does the sprite point when it is at 0 rotation

[fading mountain]

it points up. its a triangle

[slender nymph]

show your code then, sounds like you maybe have your direction calculation backwards

[rocky canyon]

then transform.up = direction should be pointing at target

did u do transform.pos - mousePosition or mousePosition - transform.pos

[fading mountain]

I tried both. The difference is that one points the object down and the other points it up.

my code is https://gdl.space/zavahusila.cs

[rocky canyon]

well if ur using Look now, ur mousePos isn't being updated

not unless OnLook is being run from somewhere

[steep rose]

np

[fading mountain]

OnLook is run every time I move the cursor

[slender nymph]

screenPosition.z = Camera.main.ScreenToWorldPoint(transform.position).z;

[fading mountain]

I tried putting it in update but it has the same effect

[slender nymph]

can you explain the thought process behind this line

[rocky canyon]

lol, i see where ur going with this..

[fading mountain]

the screen to world point values should be relative to the position of the player. If I do something like camera.nearclipplane, the values are all too small relative to the player.

[steep rose]

wouldnt RotateTowards work? as long as you give the correct vector2 values in the vector3 and just make the other one like 1 or 0 or something.

im thunkin rn

[rocky canyon]

its not that thats broken

its the way he trys to integrate the z value into all of it

[slender nymph]

that doesn't make any sense with regards to the line i am asking about. you are using a world position as a screen position, then getting the world position from that screen position and gettings its z axis for some unknown reason. that line is wholly unnecessary and makes absolutely no sense

[steep rose]

ah

[fading mountain]

screen position is used by Camera.main.ScreenToWorldPoint(screenPosition) in the very next line
now that you point it out I should definitely just use screenposition.z = transform.position.z

but I still need that line

[rocky canyon]

when u Debug directionVector just before u assign it as transform.up
it's Z coord should match ur gameobjects Z coord

[slender nymph]

do not set the z on that object. use transform.position.z for the z axis of mousePos

if you are using an orthographic camera (which i would assume you are if you're doing 2d) then the position returned by ScreenToWorldPoint when the Z axis is 0 will be the correct position but with the camera's Z axis value in the Z axis of the returned Vector3. you do not need that first assignment to the z axis of the screenPosition object, you only need to assign to the z on mousePos

[fading mountain]

like this?
mousePos = Camera.main.ScreenToWorldPoint(new Vector3(screenPosition.x, screenPosition.y, transform.position.z));

[slender nymph]

no

not at all

that's literally the same thing

[fading mountain]

you said use transform.position.z for the z axis of mousePos

[rocky canyon]

    void OnLook()
    {
        Vector3 screenPosition = Mouse.current.position.ReadValue();        
        mousePos = Camera.main.ScreenToWorldPoint(screenPosition);
        mousePos.z = transform.position.z;
    } ```

like this ^ fam

[fading mountain]

I'm sorry if I'm missing something, im still new to coding and unity

oh okay

[slender nymph]

and you are not doing that in the code you posted, you're still doing the same exact thing you were before by using it as the z axis of the screenPosition variable

[rocky canyon]

u confused urself, and us w/ the two methods, and the strange screenPosition.z thing

[fading mountain]

yep I didn't understand correctly, thanks for your help. It's working flawlessly now.

thank you spawn camp games as well

[rocky canyon]

do u know why tho..

thats the question.. lol

[fading mountain]

I was calculating the world position using the wrong z value

[rocky canyon]

simply yea. 👍 ultimately its gotta look at its own Z coord or else it tilts to and away from the camera

i just fixed up my own look at mouse script now lol. i've always used atan2 until i seen boxfriends comment

i guess its still useful in other departments

[ionic zephyr]

Does somebody know how to place (trees,rocks, bushes, etc... ) randomly in an already generated (procedural) terrain in Unity 2D?

[peak python]

so i am trying to move the tile 1 tile size down if there are no tiles below and if it is still in camera view
i have 2 issues

1. cell size is bigger than the actual tile size for some reason,
2. how i can get cell size in int and not float? so i can avoid the vector being 1.0000001

[radiant meteor]

is it a problem is i put too many regions in a script? i keep getting lost in my own code when i'm trying to work on one specific thing

[cosmic dagger]

if you get lost in your code then it's probably too long. not sure i've heard that before . . .

[radiant meteor]

i probably should organize it lol

[cosmic dagger]

each script should only handle one behaviour . . .

[zenith cypress]

The two phases of using regions:
"Wow these will make it easier to hide stuff I don't need to see!"
"Wow I hate clicking so much more where is my code aaaaaaa-"

[radiant meteor]

it's a player movement script, and it has movement, jump, walljump, different kind of movement while in the air, ground check, gravity, wall checks, and i'm planning to add dash and ground slams

[cosmic dagger]

i've seen people use #region — including myself — to section off or organize code, so it's not terrible . . .

[radiant meteor]

the more i wrote that the more i'm convincing myself to separate it in scripts

[cosmic dagger]

ground slam sounds like an attack, not a movement. all of these can (and should) be a separate script, but that involves a refactor your not willing to do (at this time) . . .

[radiant meteor]

i just felt it was more convenient since they share some variables and i dont want my inspector to be a pile of scripts

[cosmic dagger]

this makes it easier to add scripts onto GameObjects to build a player, enemy, or npc. what if you want movement but no jumping?

[radiant meteor]

also, didnt seem like things i'd re-use for other gameobjects, just the player

that is a good point

it's a lot easier to deactivate a certain mechanic

[cosmic dagger]

great for testing and bug fixing as well. only turn on the component you want to check . . .

[radiant meteor]

alright, you convinced me to spend the next half hour doing this

[cosmic dagger]

i just made a separate move and rotate script myself, for a player . . .

[grand badger]

👀

[grand badger]

ransomink surely not drunk? 😛

[cosmic dagger]

or another example: i have a gun with separate scripts for shoot, reload, fire mode. that way, i can choose what functionality i want for each gun, even automated turrets . . .

[grand badger]

I guess this goes along well when working with a designer that likes getting hands-on and experimenting in Unity

[cosmic dagger]

i first used it in the longest script i've ever written: the Timer class i made into a package. to be honest, it's only that long because i created summaries for every single field, constructor, property, and method . . .

[cosmic dagger]

honestly, it's pretty cool to make all the functionality in an SO and drag-n-drop them into their separate mechanics (components) to change the behaviour . . .

@grand badger here, you can see why there are so many lines. i made summaries so anyone using it will understand what everything does, as if i was releasing a package (asset) . . .

i done so many one-off projects or helped with certain mechanics, i've never really finished any concrete system or mechanic myself. now i have mind map of every system i'm working on and where i'm at to try and finish something . . .

[peak python]

So is there a way to get tile size that is correct?
Or cell size is correct and I am doing math wrong in the scene perhaps?
And also
Is my iteration over tiles ok?

[grand badger]

just cast to (int)

usually you'll want to be working with floats all along for more precise math, then use Vector3Int.RoundToInt(myVector3)

[peak python]

I mean I am moving constant distance each time
(Cell size)
So I assumed the int would be better

[deft grail]

var y = 1.6f / list.Count;
foreach(GameObject obj in list)
{
    obj.transform.position += new Vector3(0, y, 0);
    yield return new WaitForSeconds(0.2f);
}
``` if the y position starts at `0.4`, should this end at `2`? because it ends at 3.6 for some reason

y is 0.08 so that x 20 would be 1.6, so not sure why this doesnt work

[cosmic dagger]

we don't know what Count is . . .

[deft grail]

its 20, but the same result with 10
i want it to increase by 1.6 no matter what the count is basically

[grand badger]

I try to keep my files within 70 lines (which is about how many one screen will fit), so I'm usually not considering regions.
A single case I've justified the use of #region is when I actually had code I wanted to hide because its existence is implied.. I can't remember the use-case now though lol.

[deft grail]

which is what happens except it ends at 3.6 instead of 2 for Y position

[rocky canyon]

if ur working in grids, and cells ints are better imo

[grand badger]

code is leading us to think obj is different on each iteration, so if each object starts at 0.4, it should end at 0.4 + 1.6f / list.Count.
if list.Count is 1, then yeah it should end at 2 if the obj is at 0.4

[deft grail]

well im increasing obj each time if thats what you mean

thats inside the foreach statement

[grand badger]

the code is saying that you're increasing y of a bunch of objs

[cosmic dagger]

oh, all of my files are small; no more than 100. this was a Timer class that handled everything and expanded after requests . . .

[deft grail]

no sorry i think i did it wrong.
im looping through a list but im changing the position of a different object.
so its not obj.transform.position its somethingelse.transform.position

[rocky canyon]

classic 🙂

[grand badger]

yeah that's totally not what you're doing here 😛

[deft grail]

yeah thats my mistake on writing it in discord

[rocky canyon]

i thought we were witnessing some type of brain teaser

[deft grail]

but the one im increasing position of is at 0.4 and i want to increase it by 1.6

to make the total of 2

[grand badger]

show actual code that has the issue?

[peak python]

yeah, thats why i am trying to have all movement in ints

[rocky canyon]

need to make sure to run ur move logic in steps then

[deft grail]

    private IEnumerator Spin()
    {
        var y = 1.6f / weapons.Count;
        foreach(GameObject weapon in weapons)
        {
            Debug.Log(y);
            baseWeapon.transform.position += new Vector3(0, y, 0);
            yield return new WaitForSeconds(0.2f);
        }
        yield return null;
    }

[peak python]

wdym in steps?

[rocky canyon]

well i just mean.. its not ur typical.. bunch of move calls in update()

[rocky canyon]

im just making my way back up to this

[grand badger]

yeah, you're calling the Spin coroutine twice

your code needs work though 😛 still badly written

[deft grail]

is that what the null does? or how does it call twice

[deft grail]

whats bad about it?

[grand badger]

it's misleading again -- you're not using weapon at all besides its count

plus y is a misleading name by itself -- instead of yOffsetPerFrame or something

[deft grail]

yeah because im trying to base it off the count

so if theres 1 item or 15 or 100 i want it to increase by 1.6 anyway

[grand badger]

var yOffsetPerIter = 1.6f / weapons.Count;
for (int i = 0; i < weapons.Count; i++) {
    baseWeapon.transform.position += new Vector3(0, yOffsetPerIter, 0);
    yield return new WaitForSeconds(0.2f);   
}

[rocky canyon]

what are all those error's?

[peak python]

just was trying to use Int, didn't finish the code, says can't cram float into int

[grand badger]

no that's not what the yield return null does -- that would normally make the code wait a frame before continuing, but since it's last in your code, it doesn't do anything

[deft grail]

has the same result

[grand badger]

yeah it's the same functionality,

[deft grail]

yeah so whats the change for 🤣

foreach is easier to use IMO

[grand badger]

it's misleading

[deft grail]

idk sounds fine to me lol, not sure how the coroutine is being called "twice" though

[grand badger]

if you want to use the foreach without having it be misleading, use foreach(var _ in weapons)

[deft grail]

anyway, misleading doesnt matter
why does it go to 3.6 instead of 2

[grand badger]

I told you -- it goes to 3.6 instead of 2 because you're calling the coroutine twice, in code you don't show us

[deft grail]

im calling it once in Start, and i checked it just now with a debug.log that runs only once

    private void Start()
    {
        StartCoroutine(Spin());
        Debug.Log("Starting");
    }

[grand badger]

are you adding and/or deleting stuff from weapons then

[deft grail]

no, its just a set 20 in the inspector

[eternal needle]

just curious, why should that go to 2? you said the count was 20 i believe
1.6 / 20 added 20 times is just 1.6

[deft grail]

unless this code here is deleting/adding which i dont think it is

[grand badger]

try this instead:

var yOffsetPerIter = 1.6f / 20;
for (int i = 0; i < 20; i++) {
    baseWeapon.transform.position += new Vector3(0, yOffsetPerIter, 0);
    yield return new WaitForSeconds(0.2f);   
}

[eternal needle]

also you should add a debug in the coroutine to see when its started, not in start. not saying thats the issue though

[deft grail]

1.6 / 20 is 0.08
so i add 0.08 to the position 20 times to get 1.6 so i can have a total of 2

[cosmic dagger]

can you post the logs of y because we don't see how the end result is 2 . . .

[grand badger]

inb4 its a child of another object that has scale 0.5

[eternal needle]

where did that magical 2 come from. and where is this magical value of 3.6 coming from

[deft grail]

the chiild has a scale of 0.5 yes, but making it 1 has the same result

ah

[rocky canyon]

i think he meant the parent

[deft grail]

the parent has a scale of 0.5 yes

[rocky canyon]

mmhmm

[deft grail]

making it 1 makes it work

[grand badger]

xD

[deft grail]

see i know my code works fine

[rocky canyon]

phew, my brain was starting to hurt just spectating

[cosmic dagger]

bruh . . .

[eternal needle]

this is why its always said to not just read the values in inspector, its local values

[radiant meteor]

how do i make a variable that is checked and changed by multiple scripts?

[deft grail]

alright so the solution is just adding half of 1.6 i guess

[rocky canyon]

u can do that with public variables

[grand badger]

no smokey grass xD

[deft grail]

ffs so what i gotta do 🤣

i can code, but i cant unity 👍

[grand badger]

always approach from math standpoint

if you want 1.6 units in LOCAL scale, use transform.localPosition instead of transform.position

[radiant meteor]

oh, i think i see how, thanks man

[eternal needle]

i mean, was there actually an error of the object being in the wrong place? Again this was just a local value that you were reading.
Anyways this is very hardcoded

[deft grail]

ok yeah that works with the original 1.6 value

[grand badger]

that makes scale and potentially rotation be accounted for

[deft grail]

the scale was 0.5 on the Y, thats the only problem

[rocky canyon]

heck ya, now u got (2) solutions

[summer stump]

But what is actual problem?

[deft grail]

using position instead of localposition i guess?

[grand badger]

yeah. using local is the correct solution lol

[summer stump]

No, that is the cause of seeing random numbers. But why do these specific numbers matter?
Why does it have to be 1.6 in the local change?

[cosmic dagger]

you should create a public method that other scripts can access to update the value. don't allow other scripts to access or change the actual field . . .

[rocky canyon]

precision offsets i bet

[deft grail]

i want the final destination to be 2. the starting position is 0.4
therefore it needs to go up by 1.6

[summer stump]

That is what I am trying to ask. Why get it to 2? Because this just seems like an odd way to do it

[deft grail]

because that seems like a good number for the gameobject to end up in for it to look alright?
not sure what a "good" way of doing this or basically anything is tbh

[summer stump]

Ok. So the problem was that it didn't look good.
Got it

[deft grail]

well there wasnt really an original problem, i wanted it to move up and before i coded ANYTHING i just moved it up in the Scene

and found a value i want

[rocky canyon]

#💻┃code-beginner message

the ole gizmo ruler

[deft grail]

now i gotta do the same thing for the time for the yield return 🤣

[eternal needle]

this just looks like you could use an animation

[deft grail]

maybe idk, idk what im doing tbh
its like a cod zombies mystery box

[eternal needle]

it could be a frog jumping for all it matters. you've hardcoded moving an object with a coroutine when it could be an animation

which would give you way greater control too

[deft grail]

wait 🤔
so i can just make an animation of this moving up without any of the amount of things in the list mattering anyway?

that does make sense 😂

then i would just need to code the actual changing of things in the list

[eternal needle]

i have no clue what the list was for, and you never really stated the true problem. You did say a few times that no matter what you just want it to go to 2 on the y axis. So i dont see why the list affects anything

[cosmic dagger]

wait, you just want to move an object up? you can use Lerp for that and easing for t . . .

[eternal needle]

the only thing thats affected i guess is how slowly it goes up. in which case you still could use an animation and set the speed accordingly. even at runtime

[deft grail]

so i need it to move from a to b in idk what amount of time i guess like 2-3 seconds?
and the weapon just needs to go through each one in the list till it travels from a to b

[cosmic dagger]

if it travels from a to b, then it will go through every one in the list, no?

a = original position; b = a + 2 . . .

[deft grail]

a to b is the position.
so from 0.4 to 2
while its doing that i want the model of whats moving up to change between all the weapons in the list

[eternal needle]

right now all you have is an object that moves up by a hardcoded amount every 0.2 seconds which i really dont see why this 0.2 seconds is needed. It will look pretty jittery

basically an object moving at 5fps

[deft grail]

yeah now i realized that i need it to just go through all of them in 2-3 seconds instead of what its doing now

[cosmic dagger]

you remind me of a designer. while fixing one problem, you integrate a new design before the previous one is fixed . . . 😆

[eternal needle]

what id do, if you dont wanna use animations, is have a start and end point defined as their own gameobject. Or at least some way to visualize it in unity using 2 vector3's and gizmos. Define a float for how long the total movement should take
lerp between start point position and end point position at (currentTime / totalTime)

[cosmic dagger]

where did the weapon model changing come from?

[deft grail]

🤣

baseWeapon.GetComponent<MeshFilter>().mesh = weapon.GetComponent<MeshFilter>().sharedMesh;
baseWeapon.GetComponent<MeshRenderer>().materials[0] = weapon.GetComponent<MeshRenderer().sharedMaterials[0];

[cosmic dagger]

exactly, use two empty GameObjects (or Vector3) fields for the start and end position. another field for the duration. then use a coroutine to lerp using all three fields . . .

[deft grail]

yes my IDE is finally configured.
at the expense of half my C drive storage

[peak python]

@rocky canyon it works now
with delay it looks even nicer 🙂

[radiant meteor]

ok, so i made a get; set; for a private variable in one script and i want to use it in a different script, i reference it in Awake/Start to a variable of the same type in another script and anytime i check it, it will be updated based on that private variable, and if i change it, it will update that private variable, right?

[peak python]

also extracted the actual tile movement, cuz idk if i can adjust positions in the list during iteration through the list in c#
since moving tiles technically shall change positions

[radiant meteor]

basically turned both into the "same" variable, right?

you define where and how it changes inside of the get set which is on a public variable not a private one

and in your other script you can just reference the public one

    private int something;
    public int Something{
        get {
            return something;
        }

        set {
            something = value;
        }
    }

[radiant meteor]

yeah, i meant "that private variable" as in the variable the get set variable is getting

[deft grail]

when you change the value of the public variable, it changes the private one yes

and returns you the private one when you try to access the public one

[grand badger]

@radiant meteor mind that while OK for demonstration purposes, this is a bad practice and causes code bloating

[grand badger]

also, you can only reference objects -- int is of type struct, and will only be copied by value when you do var smth = someObj.someStruct

[cosmic dagger]

if the property has get; and set; then the private field is pointless . . .

[grand badger]

that means that no matter what changes you do to the smth variable, someObj.someStruct will not be changed

[radiant meteor]

i was mainly trying to make multiple scripts have the """same""" variable so i dont have to say "GetComponent<Script>().variable" whenever i wanted to change or get that variable

[grand badger]

Wrote the best imo conveniences a month ago: #archived-code-general message

I'd go with the [field: SerializeField] public MyClass field { get; private set; } case then

accessibility modifiers is not really a beginner topic so for now there's nothing wrong with just a public field if you're just starting (e.g.: public MyClass field;)

[ivory bobcat]

Reference the wanted component and access the wanted variable. Scripts shouldn't have to declare the same variable simply to avoid proper referencing.

[radiant meteor]

i'm confused, if this for example, "if (!MyBool)" checks "_myBool" which is in another script, and "MyBool = true" sets "_myBool", again, from another script, into true, then why not use this instead of having to reference the script in question every time i want to check/change "_myBool"? if this works the way i think it does, i only need to reference it once in start or awake

[grand badger]

@radiant meteor also just to make sure you're aware of static variables:

public class Settings : MonoBehaviour {
    public int volume;

    public static Settings instance { get; private set; }
    void Awake() => instance = this;
}
```..here you can access the volume from any script via `Settings.instance.volume`

Similarly with:

public class Settings : MonoBehaviour {
    [SerializeField] int volume;

    public static int Volume => instance.volume;

    static Settings instance { get; set; }
    void Awake() => instance = this;
}
```..here you can access the volume from any script via `Settings.Volume`

typically allowing other scripts (/users) to change a variable that could potentially affect multiple systems is a no-no

[cosmic dagger]

access modifiers aren't beginner? 🤔

isn't that the first thing you learn along with classes, fields, methods, etc.?

[grand badger]

yeah, as in I would allow my beginner mentee/student to just use public for everything instead of narrowing scope with { get; private set; }

then 2-4 weeks in I'd slap in a long-ass refactoring assignment to make everything accessible only to minimum-required scope 😆

[grand badger]

yeah but I don't think that's the thing that shines when learning about classes/fields/methods -- pretty sure those things outweight the access modifiers in the eyes of a beginner

[cosmic dagger]

maybe, i guess i'm just wired different. the first thing you type is the access modifier, so i see that as an important concept to know . . .

[grand badger]

there's also the possibility that my teaching priorities might be just weird 😛 Imagine I 100% absolutely always start with teaching about how variables translate to RAM blocks

[native thorn]

Is there an easy way to understand how world maps are usually done

[grand badger]

easiest way to understand how they can be done is to try making one and see what works 😛

how they're usually done is quite vague

[native thorn]

I'm not all that far into my world map yet

Sorry, I more so ment the logic behind translating locations and player position into map UI icons

This is done with world to screen point right?

[cosmic dagger]

that's fine. the first thing i would teach is the stack and the heap, though, i wouldn't go into gen 0, 1, or 2 . . .

[grand badger]

oh yeah my var --> RAM lesson also intends to teach the stack and the heap 😄

nice to hear there's at least someone else who finds that absolutely fundamental

[cosmic dagger]

well, the stack vs heap convo would lead into reference types and value types . . .

[grand badger]

Ah. Then it's a very complex task. Might wanna look into the following concepts little by little:

• Fade in/out (e.g.: Loading screens)
• Scriptable Objects (e.g.: EntryPoint if you wanna add scene changing like entering buildings)
• Callbacks (e.g.: OnSceneChanged --> TeleportPlayer(EntryPoint))
• Minimap (e.g.: Projecting a 2D icon for a 3D Object over a 2D-projected 3D world)

Mind though that making a minimap is quite a complex task. Since you're asking in #💻┃code-beginner, I'm inclined to recommend skipping it and going with fake world map + transitions

High-quality world maps (like WoW's) are essentially fully-expanded minimaps.

[cosmic dagger]

whoa, it disappeared . . . 😲

Hey guys.. Is there a way to show the value of a variable in the inspector but in a way I cant change it? Like just readonly? So I dont have to use Debuglog to see if the value is changing?

[cosmic dagger]

use the NaughtyAttributes package or make a custom inspector . . .

the quickest way is to switch the inspector to Debug mode. it will display private variables for you . . .

[solemn fractal]

how do I do that?

[cosmic dagger]

click the three vertical dots on the side of the Inspector tab and select 'Debug' during gameplay to show private fields . . .

it's right next to (after) the lock icon . . .
