ahh simple as that

[rich adder]

properties for ya

[rocky canyon]

soo even if u could manipulate it.. it'd do nothing for ya

[ripe shard]

structs

[rich adder]

yeah because its value type

[rocky canyon]

words 😈

[rich adder]

lmao

[rocky canyon]

i love lamp

[rich adder]

wait let me remove it before i get muted

[cinder crag]

damn , is there any workaround for that

[ripe shard]

you'll get mutated

[rocky canyon]

thers a different timescale u can change if i remmeber correctly @cinder crag

navarone would know

[rich adder]

computerman

[rocky canyon]

unscaledTime

[rich adder]

wassthat?

[cinder crag]

its only readonly

[rocky canyon]

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

ohh is it..

TIL

[rich adder]

oh Timescale ? It would not affect Inputs unless you're doing * time.deltaTime

[rocky canyon]

im still looking.. i havent had this issue yet.. but im sure i wil

soo might as well learn w/ ya

[rich adder]

yes assigning value to unscaledTime makes not much sense, its like trying to assign time.deltaTime

[cinder crag]

smth like this?

[rich adder]

what are you even doing here lol

[cinder crag]

shop , when im the shop area and press E , it opens and when i let go of E , it closes the shop

@cinder crag some fast resources i found

[rich adder]

why are you multiplying time.deltaTime for timescale

[rich adder]

theyre not using new input system

[rocky canyon]

a few of em aren't some of em are..

just covered bases

[rich adder]

timescale would not affect inputs, but it does affect physics loop

[rocky canyon]

maybe using the new input system could be a solution

[cinder crag]

maaannn

[rocky canyon]

iono ¯_(ツ)_/¯

[rich adder]

putting inputs inside triggerstay is likely a big issue

[cinder crag]

yeah

maybe a raycast2d?

[rich adder]

use a bool you detect in Update for inputs

[rocky canyon]

if this is true.. then his issue is not what he believes it is

ahh physics

[rich adder]

yeah they probably have something else wrong

[rocky canyon]

yup yup

i have to re-do my pause system.. b/c it uses timescale.. i dont believe i wish to use that

[rich adder]

mainly physics and animations are 100% affected by timescale (that includes fixedupdate etc.)

[rocky canyon]

i instead need a static bool to wrap my stuff up in

to stop systems from running

[rich adder]

I use a static Event

[rocky canyon]

ya i mentioned this earlier.. #💻┃code-beginner message big spoonfed dump

[rich adder]

if something in script cares about "pausing" it will do so

[rocky canyon]

sounds gucci

[rocky canyon]

unity event or delegate?

[rich adder]

Action

public static event Action<bool> OnGamePaused

[rocky canyon]

ahhh. okay.. I have a custom class called Action

mmhmm :smart:

[cinder crag]

okay fixed evetrything

[rocky canyon]

can either be automatically triggered (onenable) or.. manually called

[cinder crag]

oh my god

even the pistol dmg being bugged

[rocky canyon]

look at you "levelling up"

[cinder crag]

the problem was i wasnt puasing the game when in the shop so when i press to buy the pistol , it charges the bow then destroys it and adds the pistol fast so thats why it would be stuck with the bow dmg

so now that im pausing my game it works epicly

[rocky canyon]

awesome! glad u trouble-shot and figured out what the real issues were

my player still jumps around while navigating my Pause menu 🫣

lmao

im glad it doesn't just <crash> lol

my problem is the exact opposite.. (when i built my pause menu) i was under the assumption that everything would pause..
MouseClicks do not count

my player doesn't move around (b/c of physics) soo i thought if he didnt move he couldnt shoot.. thats not how it works

[rocky canyon]

im gonna yoink this for my system if u dont mind 🙂

[cinder crag]

https://gdl.space/vujisecopu.cpp i jsut did this and it works fine lol

[rich adder]

doooitt

[cinder crag]

even made it soif u press E again , it closes it

fixed the problem i had since last night , man that feels good

[rocky canyon]

doesn't it?

[cinder crag]

yes indeed

i love coding but man its painful

good for experience

[languid spire]

if you think coding is painful, wait until you actually start programming

[rocky canyon]

it gets easier.. thats when u gotta step ur game and make it painful again

(thats when ur learning)

[zenith crown]

Spawn camps u used a character controller right?

How did you fix the camera when crouching so it changes eye heights

with the crouching

[cinder crag]

trueer

[sand heath]

Move the camera target down

[steep rose]

you could just scale your parent object so the camera target scales with it

thats what i do

[zenith crown]

What do you mean with camera target?

[zenith crown]

Can you explain painfully detailed cause i dont understand

im still really new to unity

im 4 days in

[steep rose]

is your camera in your character or in an empty?

[zenith crown]

In my character

[sand heath]

You're still using a base unity camera aren't you

[cinder crag]

it didnt get fixed , the pistol dmg is now 0 , the buy happens when i shot and enemy with the bow doesnt matter what dmg i deal then go to the shop , buy the pistol and the dmg is still 0

[zenith crown]

Not the one thats provided when creating the project

[sand heath]

You should be using a cinemachine camera if you want anything more complex than a static camera

[zenith crown]

Let me check what im using

[steep rose]

so scale your parent object down and it should move your camera down, although janky. otherwise you could make another script that makes that camera object snap to another object i this case an empty called camtarget. and it will scale the camtarget instead of the camera

easier

and you do not need cinemachine to make good camera movements, you can code them too.

[rich adder]

worse way to do it scaling the player entirely

the camera target / offset is the best way

[steep rose]

every way is different

[cinder crag]

head be hurting

[steep rose]

it does that

[rich adder]

yes but not every way is good 🙂

[steep rose]

scaling the player down is an alright way to do it as long as you are not scaling camera.

[zenith crown]

Well atm the target is the character controller itself and its offset with 0.65 lu

[rich adder]

yeah u do that, its gonna create worse problems lol

[steep rose]

i do, i have no problems

[zenith crown]

also what does it mean when someones code isnt "safe"

my friend said that to my code

[polar acorn]

Depends on the context

[eternal needle]

Ask him what he meant. Could mean a ton of things in the context of a beginner

[polar acorn]

It could mean prone to errors, it could mean vulnerable to attacks

it could mean literally using the C# keyword unsafe

[eternal needle]

He could feel very threatened by your code

[zenith crown]

He said that to the way i used enums

[polar acorn]

What is "The way you used enums"

[rich adder]

nsa watching their code

[zenith crown]

I simply sent this screenshot and he called it unsafe

the use of enums in here

[round plover]

having a problem i want my cube to stop when it hits the obstacles and i got it to work but it only works for 3 when i add a new obstacle and i run into it with my cube it will keep going idk why

[rich adder]

how do you figure we know whats wrong from these screenshots alone?

[eternal needle]

I too feel threatened by this

[zenith crown]

Are they on the same collision layer? Do they have collision boxes?

[polar acorn]

The fact that you're casting them to int to store in MovementState means that MovementState is just an int. Meaning it can hold any int, not just values the enums represent, which can lead to errors. Why isn't MovementState of type MovementStates?

[round plover]

well i was wiating for someoen tp respond so i can go more in depth

[polar acorn]

Also this

[round plover]

2 work fine but the 3rd one doesnt work

[rich adder]

thats a waste of time. Next time clearly state the issue and show the appropriate inspectors and code

[zenith crown]

ahh makes sense

well it works and i dont use the variable yet so im perfectly fine with how it is atm

[round plover]

collision layer?

[polar acorn]

You should change the type to MovementStates instead of int

It'll also be significantly easier to work with

[round plover]

collision layerZ?

[zenith crown]

In your inspector window top left you can see what collision layer they are on. Its always on default in the beginning but for safety change them all to the same collision layer

[cinder crag]

anyone know how to fix this?

[zenith crown]

idk what that means im afraid

[polar acorn]

Change the type of the variable

to the enum type you've made

[zenith crown]

ohh now i get it

[polar acorn]

The entire point of an enum is to be a type you can store in a variable

[round plover]

is it beside layout?

[zenith crown]

The only course i took which was 4 hours before diving in the deep end kind off skipped past it a little bit

[zenith crown]

a bit below

it says layer

[round plover]

ph yeah

oh

[zenith crown]

Yeah that one

do that on all collisions so they are on the same layer

[round plover]

kinda lost ngl

mb

[zenith crown]

dw its a part of the process

[round plover]

what layer do i put it on

[zenith crown]

Which ever you want aslong as they are on the same one

are you following a brackeys tutorial?

[round plover]

yeah lol

[zenith crown]

haha knew it

[round plover]

he doesnt do anyuthing with layeers tho

layers

it al works the same

[tranquil hollow]

what software you use to create yours sprites? (Pixel Art)

[zenith crown]

yeah cause default hits all of them but im teaching you a good habit to have so they only hit what they are meant to hit

[raw token]

Probably a question for #🖼️┃2d-tools or #🔀┃art-asset-workflow

[zenith crown]

pixilart

is solid

its a website

but works well

[round plover]

the problem is that when i collide with the three obstadcles i have rn there fine i wrote it to when it hits an obstacle it stops but some obstacles dont work and my cube just continues on its way

[tranquil hollow]

ok

[zenith crown]

are the collision boxes checked?

in the inspector you see the mesh and collision box

[round plover]

yeah

[zenith crown]

collision box needs to be checked for collisions to work

[round plover]

it is

[zenith crown]

How fast are you throwing the box

[round plover]

wdym

[zenith crown]

If its unreasonably fast it could go thru the thing without a frame being loaded in to see what actually happened

[round plover]

no its not to fast

but idk why when i plant new obstacles it doesnt work

[zenith crown]

that is pretty odd idk what it might be

[polar acorn]

Show the inspector of an obstacle that "doesn't work" and if possible one that does

[round plover]

oh wait

when it hits, my playermovement doesnt turn off

off

only foes for the three i have on right now

weird

[polar acorn]

What is supposed to be turning off and what makes it do so

[zenith crown]

well im going to bed so ill let the others help you out

its getting late in CET

[round plover]

it tunrs of the collision of my cube and obstacle colliding

turns off*

wait

[polar acorn]

What is the "it" that turns off collision and how does "it" do that

[tranquil hollow]

do u recomend another one to dowload?

[polar acorn]

MSPaint

[still pond]

Does this mean that im trying to access a deleted object?
NullReferenceException: SerializedObject of SerializedProperty has been Disposed.

[round plover]

okay when my cube collides withb the obstacle the obstacles are coded to turn off my playermovemtn when impacted with my cube

[polar acorn]

Check the stack trace, it'll tell you what functions called what to get to that error. If none of it is in a script you wrote, you can probably ignore it

[polar acorn]

Okay what is that code

[round plover]

it works for 3 obstacles but the rest dont work

[toxic pine]

i have this line to acces the playerscript: public Playerscript script;

but for some reason i cant drag the playerscript inside of unity

[slender nymph]

make sure you are dragging an instance of the component and not the script file itself

[polar acorn]

Are both objects in the scene

[toxic pine]

no

[polar acorn]

Then you cannot drag one into the other

I'm assuming one of them is a prefab

you cannot drag a scene object reference into a prefab

i want it to just stay as Obstacle

@round plover Why are you posting outside of the thread again?

You need to debug that to get an idea

track down the origin of values

See the debugging guide in the pinned messages

[cinder crag]

im already debgging and i literally dont know where the problem comes from

[fickle plume]

Then post your attempts here, someone will guide you how to do it properly.

[steep rose]

we would need to see pistol damage script and bow script to find this issue

[cinder crag]

theres no bow script or pistol damage script , its jsut one script that handles all of that

[steep rose]

lets see it

[cinder crag]

https://gdl.space/tamiyuliba.cs

theres not a single line of code that sets the weapon dmg to the bows dmg , i looked in every goddamn script and i cant find one line of code that does that

what is the WeaponStats script and can we see it?

I FIXED IT

OH MY GOD

I FIXED IT

[summer pilot]

Trying to create a 3D game that operates like a 2D game (much like overcooked! and plateup!

the way my character moves right now is fine, however when I stop moving the character automatically rotates back to facing north.

how can I make it keep it's current rotation when the player stops their input?

using UnityEngine;
using UnityEngine.InputSystem;

public class PlayerController : MonoBehaviour
{
    public float speed;
    private Vector2 move;
    public void OnMove(InputAction.CallbackContext context)
    {
        move = context.ReadValue<Vector2>();
    }

    void Update()
    {
        movePlayer();
    }

    public void movePlayer()
    {
        Vector3 movement = new Vector3(move.x, 0f, move.y);

        transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(movement), 0.05f);

        transform.Translate(movement * speed * Time.deltaTime, Space.World);
    }
}

sorry i didnt respond, i was making potatoes

yummy

[cinder crag]

enjoy ur potatoes

and nw

[teal viper]

The reason(or at least one of) is you using slerp incorrectly. Check the documentation and see what the third parameter is supposed to be.

[cinder crag]

i wanna show my game here like 1 vid of it , but idk if i can

[teal viper]

#1180170818983051344

[summer pilot]

the 3rd param is the speed in which the player rotates right?

[teal viper]

No. Did you read the docs?

[teal viper]

Read the description

[teal viper]

And yes, you can see in the example that they use it differently from you

[summer pilot]

"Use this to create a rotation which smoothly interpolates between the first unit quaternion a to the second unit quaternion b, based on the value of the parameter t. If the value of the parameter is close to 0, the output will be close to a, if it is close to 1, the output will be close to b."

from what I am understanding
take point a (my current rotation)
take point b (take the location of where i want to move to and grab the rotation that would cause me to look)
but im confused on wtf T even is, if it's not the rotation speed

[teal viper]

Yep, that. It means that you need to change t overtime and needs to reach 1 eventually, if you want to get an output that is equal to b.

[teal viper]

It's time of the interpolation

Do you understand what an interpolation is?

[summer pilot]

not really

i thought i had a grasp of it, but im confused

[teal viper]

Imagine a slider going from 0 to 1. t would be the value where that slider is currently at.

If you want to slide it to 1, t needs to be 1.

Interpolation is taking two values and returning a value in between them based on t, where 0 would be equal to a and 1 would be equal to b.

[steep rose]

ah i understand, i never knew what slerp did

[toxic pine]

im using this to make "frisbee" come to a stop but for some reason it doesnt work if (collision.CompareTag("stop point"))
{
Debug.Log("STOOOP NOW");

            frisbee.GetComponent<Rigidbody2D>().velocity = Vector2.zero;


        }

[summer pilot]

so i need T to gradually move t from 0 to 1 over time from the point of pressing the key to when it starts to move in game

[teal viper]

If it's 0.05, that would be 5% between a and b

[toxic pine]

frisbee is a prefab

[teal viper]

Yes

[summer pilot]

so how would i go about doing that?

instead of having a flat value

[mint remnant]

Lerp

[summer pilot]

Lerp?

[teal viper]

Well, you can start with how they do it in the example

[summer pilot]

slerp or lerp? im confused

[teal viper]

Either one. The way you use them is the same

[summer pilot]

okay

[teal viper]

That being said, in your case you might want to use a different function

[summer pilot]

how come?

[teal viper]

One that moves the rotation by a flat value

[steep rose]

is the stop point a trigger? does it actually have the tag?

is the script on the object?

[teal viper]

Because your a is constantly changing

[summer pilot]

okay im getting confused can we walk through this from the top

[sand heath]

"it dont work" isn't a detailed enough description of the problem

[summer pilot]

my a is my current rotation
my b is the rotation i want
my t is the timeCount, which is where in the "slider" my rotation is currently sitting

my a and b are always changing, so you want me to have a fixed rotation value

[toxic pine]

yea the debug.log works but the rest doesnt

[summer pilot]

but i don't understand how that makes sense if you told me that having a fixed value where timecount goes is my issue

[teal viper]

1. You're using lerp/slerp incorrectly.
2. You're doing it because it doesn't suit you use case.
3. There are better ways to move rotation fitting to your needs.@summer pilot

[sand heath]

what exactly happens to frisbee when you get that 'stop now' message

[steep rose]

            if (collision.CompareTag("stop point"))
            {
                rigidbody RB;
                Debug.Log("STOOOP NOW");

                RB = frisbee.GetComponent<Rigidbody2D>()
                RB.velocity = Vector2.zero;
            }

try this

[sand heath]

wrong reply

[toxic pine]

it keeps mmoving

[steep rose]

ah

okay

now we are getting somewhere

[summer pilot]

please explain, i dont get it

[sand heath]

there is no functional difference between this and what they have

[summer pilot]

i feel like im understanding how slerp lerp works

[steep rose]

i see that now thats why i replied to him in the manner i did

[summer pilot]

but its not usable in my case?

[toxic pine]

yea nothing changed

could it maybe be because the frisbee is a prefab

[sand heath]

Is the frisbee maybe receiving a constant force thats overriding this change?

[sand heath]

can you send the full code

[toxic pine]

oh yea that probally it

[teal viper]

Good. What I'm saying now is that you shouldn't use slerp at all in your case.

[sand heath]

you could be modifying the prefab instead of the instantiated gameobject

[summer pilot]

what should i be using instead?

[teal viper]

Go back to the documentation and open the Quaternion page. Look at what methods it has available and what they do. See something fitting?
Tip: look at the static methods.

[toxic pine]

ill have a look

[summer pilot]

Angle & FromToRotation both seem they could work?

[teal viper]

What about RotateTowards?

While you certainly could do it with angles, that would just make things more complex than they need to be.

[toxic pine]

i got a var in the update method that i cant use in the trigger for some reason do you know why

[sand heath]

no because you haven't sent the code

[toxic pine]

mb mb

beware youre gonna be looking at spagheti code

[summer pilot]

im trying that now, but when i try to input the step var, i get this issue

[sand heath]

you have multiple PlayerController classes imported, both with the speed field

[ivory bobcat]

It says you've got two speed variables declared

Showing the console window might reveal other issues that you've got

[teal viper]

Sounds like you have 2 speed fields.

[summer pilot]

yep, i spaced that sorry

                bullet.GetComponent<Rigidbody2D>().velocity = frisbeetransform.right * frisbeespeed;
            }
            if (isfacingright == false)
            {
                bullet.GetComponent<Rigidbody2D>().velocity = -frisbeetransform.right * frisbeespeed;
            }


}


public void OnTriggerEnter2D(Collider2D collision)
        {
        if (collision.CompareTag("stop point"))
        {
            Rigidbody2D RB;
            Debug.Log("STOOOP NOW");

            RB = frisbee.GetComponent<Rigidbody2D>();
                RB.velocity = Vector2.zero;
           
        }

bullet is the right var

[sand heath]

how is update even being called?

its not written correctly

do you have your IDE configured?

[ivory bobcat]

Is this real code and not pseudocode? Update needs to be capitalized.

[summer pilot]

player doesn't rotate at all now :/

public class PlayerController : MonoBehaviour
{
    public float playerSpeed;
    private Vector2 move;
    public float rotateSpeed = 1.0f;
    public void OnMove(InputAction.CallbackContext context)
    {
        move = context.ReadValue<Vector2>();
    }

    void Start()
    {

    }
    void Update()
    {
        movePlayer();
    }

    public void movePlayer()
    {
        Vector3 movement = new Vector3(move.x, 0f, move.y);

        var step = rotateSpeed * Time.deltaTime;

        transform.rotation = Quaternion.RotateTowards(transform.rotation, Quaternion.LookRotation(movement), step);

        transform.Translate(movement * playerSpeed * Time.deltaTime, Space.World);
    }
}

[toxic pine]

i rewrote the update part because i didnt want to also send the part of the code that has nothing to do with this

[sand heath]

im suspicious of 'frisbee'

[toxic pine]

https://gdl.space/osavajacal.cs

[teal viper]

Try increasing that speed parameter to something like 180.

[summer pilot]

the rotation speed?

[teal viper]

Yes

[sand heath]

Is frisbee set

[toxic pine]

wdym

[sand heath]

in the inspector

[summer pilot]

rotates v slow (fixed by turning the value up to 500), but still rotates back to north position after i let go of the controls

[toxic pine]

yea

[sand heath]

Does frisbee have a rigidbody2D

important that its rigidbody2D not rigidbody

[ivory bobcat]

Reference the object as the common and specific component type to avoid having to make get component callscs public Rigidbody2D frisbee;You can always access the GameObject component with the gameObject property - cached and faster than a Get Component call.

[toxic pine]

yea

[sleek marten]

I've disabled my pause menu button start and I use a script to turn it on at runtime

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

public class PauseActivator : MonoBehaviour
{
    [SerializeField]
    private Button pauseButton; // Assign this in the Inspector

    void Start()
    {
        // Ensure the pause button is enabled
        if (pauseButton != null)
        {
            pauseButton.gameObject.SetActive(true);
        }
        else
        {
            Debug.LogWarning("Pause button is not assigned in the inspector.");
        }
    }
}

and that works well enough

but this ONLY works on one scene

every other scene, the pause UI has to be enabled otherwise the buttons inside it won't work when I load into that scene from the start

I really don't want to have to disable and enable the menu every time I leave a scene in the editor

[ivory bobcat]

Also, if you're trying to stop the instance of a frisbee maybe the trigger function should be on the frisbee object instead of this object. Else check if the frisbee made contact with this object (assuming this is on the player - implied by naming conventions: player script) and access the component (rigid body) on the other object to modify its speed and whatnot.

[sand heath]

i wonder if its something to do with changing the velocity outside of fixedupdate

[sand heath]

i have no idea what you're trying to do tbh

can you describe your goal?

[toxic pine]

nsh i kynda want the frisbee to float in place

[copper python]

agreed ngl, this is my 5th time reading over it XD

[toxic pine]

idk man

[sand heath]

pause menu button start is a lot of words

[sleek marten]

I'll need a min to break down what I'm doing cause there's a few steps (I haven't made a pause menu before)

[copper python]

I'd say also enable/disable the ui on runtime?

[sand heath]

if you can't describe your goal, you should take a step back

[teal viper]

That happens because your input is 0,0 in rest position and you still calculate a rotation for that value.

[summer pilot]

how do i fix that?

[sleek marten]

It's really not much of anything, I'm just a little tired

let me collect my words

[summer pilot]

i don't want it to rotate when the player isnt actually moving

[sand heath]

i get it, im just saying that taking a step back and looking at your problem as a whole will often show you the solution

describing the problem and how you're trying to solve it to yourself also helps with that

[sleek marten]

I've got a pause button. Inside I have a single option to mirror the gameplay (it's for mobile and it makes it easier to play left handed). I am putting the button in the pause menu so that it's always accessible but not in the way.

That button must ALWAYS be enabled when a scene is loaded otherwise it won't work. Enabling it once you're in the scene breaks it. Therefore the pause menu must also be active otherwise the button will still not work.

My idea was that if I enabled it at runtime then I could get around this. This idea works ONLY at my first scene. If the pause menu is disabled in any following scene then the button to mirror will not work.

If the pause menu is enabled in any subsequent scene first, then it all works fine!

But now I have the issue of the pause UI ALWAYS needing to be turned on (which blocks the editor)

[copper python]

hmm that makes sense in a logical way

[sand heath]

why does enabling it once youre in the scene break it

[sleek marten]

Oh that's easy to explain

I have my script search for a component (by string in this case)

it's not good but it works in a pinch

[sand heath]

why

[sleek marten]

however if any of those listed things are disabled, then it can't find it

I tried doing a serialized field

but that works even less

not sure why

[sand heath]

ok first off you can reference the main camera with Camera.main

there's no reason to even have the first thing

[copper python]

Heard of the Singleton system before?

[sleek marten]

no

[copper python]

Look it up, it's usefull

[sand heath]

thats not what they need

why dont serializefields work?

[sleek marten]

The script uses PlayerPrefs because I wanted the setting to be persistent across scenes

when I use a SF, the game just forgets what's supposed to populate the field and leaves it empty

[sand heath]

What?

[summer stump]

DDOL is better for inter-scene persistence. Use playerprefs only for inter-runtime persistence

[sand heath]

Ok first

[SerializeField] Camera secondCamera;

did you do it like this?

[sleek marten]

yes

[sand heath]

ok and you filled the slot in, what do you mean it forgets?

[teal viper]

Then make a check and only rotate it when the input is not 0.

[sleek marten]

@sand heath I use using a DDOL method before, but the field would be blank when I went into a new scene

[summer pilot]

how do i get my input value as a variable?

[sand heath]

because the cameras dont transfer to the other scene

[copper python]

What's DDOL? o_O

[sleek marten]

Don't Destroy On Load

[sand heath]

dont destroy on load

[sleek marten]

I've got a copy of the camera's on every scene

[copper python]

ah that makes sense ty

[sleek marten]

so that wasn't the problem

[sand heath]

that would be the problem

just because you made an object that looks the same doesn't mean it is the same

even if its a prefab

[summer stump]

Oh I see, because you need a reference to the new scene

[sand heath]

so when you go to a new scene you need to set those fields again

[teal viper]

You already have it in your code though. You wouldn't be moving at all if you didn't have it. Think.

[sand heath]

main camera you dont need to worry about, second camera i guess is fine to find by name but its really not optimal

you could find by tag which would be much faster

[sleek marten]

I'm taking some time to optimize these systems before I move on

[copper python]

Sounds like a good plan

[sleek marten]

so if there's a better way to do it, that's what I need to do

[sleek marten]

not a bad idea

what do I do about the button, though?

OH THEY TAKE TAGS TOO

wow

[copper python]

what do

[sand heath]

thats like asking about if the bobble head made it in a car crash

[copper python]

What does that mean? XD

[sand heath]

whatever the problem is is deeper than this button 😭

[sleek marten]

I'm worrying about the wrong thing

[summer pilot]

something like this i presume?
but i have an error, how else would I right "does not equal"

[copper python]

console log would say true

[sand heath]

movement != Vector3.zero

[sleek marten]

I'm trying to make a pause menu that has a persistent setting inside it

[summer pilot]

this worked beautifully

[copper python]

Vector3.zero equals new Vector3(0, 0, 0), or 0 btw

[sand heath]

Alright we'll start with how the pause menu works

Is it just a prefab you have in every scene?

[sleek marten]

I've got the ability to pause the game time

and a button that pulls the UI up

[sleek marten]

they ain't even prefabs

the camera's aren't, atleast

neither is anything in the UI

[sand heath]

why not

[sleek marten]

didn't think about it

didn't know they needed to be

[sand heath]

if you ever use an object more than once and you need changes to be synced you should use a prefab

[sleek marten]

didn't know a camera could be a prefab, either

but I'll do that now

[sand heath]

all gameobjects can be prefabs

a camera is literally just a gameobject with a camera component on it

[sleek marten]

so should both the Main and Second be prefabed?

[sand heath]

refer to what i said earlier:

[sleek marten]

alright that's done

[sand heath]

are they identical?
do you want them to stay identical across all instances?

[sleek marten]

yes

[sand heath]

then prefab

[sleek marten]

Done

[silent tree]

could anyone help me figure out why my game object isnt centered? when i put my game object at (0, 0) it isn't in the center, but things like my camera are centered at (0, 0)

[sleek marten]

SF them next, I assume?

[summer pilot]

is it a child under another object?

[sand heath]

is it a child of another gameobject

[cosmic dagger]

is it a child of another GameObject?

[sand heath]

well like i said earlier, serializedfields wont persist between scenes because the cameras dont persist

[silent tree]

the sprite is broken up into both a child (the base) and the tower itself as the parent, but they are both at 0,0

[sleek marten]

oh so then I should use tags?

[sand heath]

whenever you load into a new scene you need to update those fields

yes use a tag to find secondCamera

main camera can be found by camera.main

[cosmic dagger]

where is the pivot located on the GameObject?

[sleek marten]

how should I tag my UI? Just call it all "UI"?

[sand heath]

you dont need to tag everything

only tag things that need tags

[sleek marten]

well the pause menu needs to be found across scene, so that should be tagged shouldn't it?

or atleast the specific button within it

[silent tree]

is the circle the pivot? thats almost in the center

[sand heath]

well the pause menu could be a singleton

https://gameprogrammingpatterns.com/singleton.html

[cosmic dagger]

no, that looks like the collider. the pivot is located where the handles appear: to move, rotate, or scale the GameObject . . .

[silent tree]

i meant the small blue circle near the center not the green one

[cosmic dagger]

yeah. just select th emove tool to see where the handles appear. that's the pivot/center of the GameObject . . .

can you show us the scene hierarchy to display the GameObject?

[sand heath]

public static MyClass Singleton {get; private set}

private void Start()
{
  if (Singleton == null)
  {
    Singleton = this;
    DontDestroyOnLoad(gameObject);
  }
  else
  {
    Destroy(gameObject);
  }
}

@sleek marten

[sand heath]

then accessing the singleton:

private void Update()
{
  if (Input.GetKeyDown("P")
  {
    MyClass.Singleton.MyMethod();
  }
}

@sleek marten

[sleek marten]

Oh no that means I have to redo this pause menu code

untangling it to fit this in would probably take longer

[sand heath]

Not like it works rn lol

Surely you have version control set up

[sleek marten]

No

I'm only on week 1 and so it's a cobbled together mess

[sand heath]

They never do

[cosmic dagger]

what position appear from the inspector?

[silent tree]

0,0 for both the base and the tower

[sand heath]

Have you tried just following a tutorial first

I'm assuming you have

But it broke down at some point

[sleek marten]

yeah and they're all 6 years+ out of date or go over things that I'm not doing

[sand heath]

The only thing that might be outdated is input

Pause menus are pretty straightforward

[sleek marten]

yeah that's what I thought too

it's really cause of this button, I think

and it's weirdness that I have to work around

I think fixing that will make the other stuff easier

[cosmic dagger]

right underneath "Scene", change "Center" to "Pivot". does it change the position at all?

[silent tree]

it didnt move, but the handles are now at 0,0

[cosmic dagger]

okay, that's the actual pivot. before, you were on "Center" which moved the handles to the center of the GameObject, not the actual pivot location . . .

[silent tree]

can i move the pivot to a custom point?

[cosmic dagger]

yes, use the sprite editor . . .

[sleek marten]

@sand heath thanks for the help! I'll be busy for the next day or so getting this sorted

god willing I only have to address it once

[sand heath]

Don't worry you'll have problems like this every day

Where you realize the way you were doing something was wrong and you have to redo it

[sleek marten]

That's what I'm expecting for about everything I have so far since I'm in the "just make it work" stage

I'm getting it ready for future proofing, which starts with a functioning pause menu

[silent tree]

found it, Thank you!

[steep rose]

i would ask this question in #💻┃unity-talk

[thorn lake]

Oh ok

[cinder crag]

Oops wrong channel

[copper orbit]

what does <> in class declaration mean again? e.g. public class Grid<TGridObject> { { }

is it related to generics?

[sour fulcrum]

Yeah, it's defining the type that's been used for the generic

    public static List<char> alphabet = new List<char>
    {
        'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'
    };

        foreach (char letter in stringCode.ToCharArray())
        {
            Debug.Log(letter.ToString() + " - " + alphabet.IndexOf(letter).ToString());
            newSeedCode += alphabet.IndexOf(letter).ToString();
        }

alphabet.IndexOf(letter).ToString() is returning -1 and I'm not sure why?

a quick google didn't pop up anything about indexof returning -1 and I haven't seen that before

[frosty hound]

Quite literally the first few lines

[teal viper]

You probably don't have that character in the alphabet list

[sour fulcrum]

I didn't know certain types had specific stuff like that, was looking at indexof in general apologies

[sour fulcrum]

Yeah just found it tyvm

[last edge]

does anyone have a 2D character state system that i can have? lol

basically for when your character get snared or knock back

[copper orbit]

yup youre definitely creating a list of generics there. I am asking about use of <> on the first lines of class

[ivory bobcat]

Where was the error thrown? Show the complete error

[ashen trail]

What is wrong with my code? I'm trying to keep my player with from getting out of bounds, but when he reach's -5 on the x position the player will get teleported to -5 on the z position too, same thing in the opposite direction.

[muted narwhal]

Messed up a bit, looks like slot returns null, but... i don't really know.

[ivory bobcat]

Looks like a lazy/bad copy n paste.

[raw token]

if that's line 42, _slotPositions is null

[ashen trail]

Man, I've been doing the unity learn courses I don't know any other way.

I'm just beginning

[muted narwhal]

Yeah, it's null at start, but I'm adding something here, so why would it return a null?

[raw token]

The list must be initialized before you can add things to it... When you're working with reference types, variables just store a reference to them. Declaring a variable for a reference type just creates a container for that reference - but you still have to tell it what it should reference

[summer stump]

May not be the issue, but those should likely be else ifs

[ashen trail]

okay, I will try that

[raw token]

That was a bit of a mess of an explanation on my part 😅

[muted narwhal]

Maybe you could explain it a bit simplier? English is not my main language, and I didn't understand 80% of your message, especially since I'm kinda new to C# 😓

[ashen trail]

The else if didn't help although it was a good suggestion, you also for some reason can't keep the player within the zposition you want him.

[raw token]

A "variable declaration" is just creating a variable with a type and a name:

List<float> foobar;

I now have a variable foobar. The type of the variable, List<float>, just describes what value the variable can hold. So I've sort of created a "box" that can hold a specific thing, but there's still nothing in it.

Right now, the value of foobar is null. It can refer to a List of floats, but I haven't told it which List of floats it should refer to. There's no value. The box is empty, because we haven't given it any value.

"Initializing a variable" is assigning a value to it for the first time. If I want it to refer to a brand new empty list, I have to write code to explicitly create that list, and then assign it to the variable:

foobar = new List<float>();

Now foobar is no longer empty - it refers to that specific empty list.

[muted narwhal]

Of course it shouldn't have been so detailed, but thanks, lol

I'm more interested in the word "reference", I hear it often but don't understand its meaning in C#.

[raw token]

I sort of enjoy trying to simplify and verbalize things I think I know... it's good exercise 😁

[ivory bobcat]

Did you ever get this fixed?

[ashen trail]

No

[summer stump]

Should the second two conditions not be checking the z position? They are checking whether the x is within the zRange

[ashen trail]

they are, how come they are trying to check x? Because it is checking for zRange

OHHH sorry

[summer stump]

A reference can be thought of as an address. It points to a place in memory. The different things using that address will all "see" the same data

Value types will copy the data and see their own copy

[ashen trail]

I guess I'm just blind

[summer stump]

Easy mistake, no worries

[ashen trail]

thx for the help

[raw token]

When we create a variable, it's associated with a specific address in memory.

"Value types" are usually simple data like floats and are stored directly at that address. Assigning the value of one such variable to a second copies the value into second variable's address - so they're both unique:

float a = 5.2f;
float b = a;
a = 6.5f;

Debug.Log(a); // 6.5
Debug.Log(b); // 5.2

Meanwhile more complex data is usually a "reference type," meaning that instead of directly storing the value at the variable's address, it may be stored elsewhere, and the variable just holds the address of where it actually is. So our variable is just a reference to it.

When you assign one reference type variable to the other, it copies the address of the data into the second. So now they both refer to the same data instead of unique copies:

class FooBar {
  public float baz;
}

FooBar a = new FooBar();
FooBar b = a;
a.baz = 3.14159f;
b.baz = 42f;

Debug.Log(a.baz); // 42
Debug.Log(b.baz); // 42

[muted narwhal]

Ah, thank you so much

[raw token]

NP... My description of the addresses in particular may not be entirely accurate, but I think may be fine enough for a broad overview 👀

[ember tangle]

What are the "< >" when I use GetComponent<Foo>() or public event Action<bool> Bar

[thorny basalt]

Type parameters.

They specify the type when using a function or creating an object

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/generics/generic-type-parameters

Here is an article that goes more in depth. :)

[ember tangle]

I guess what im curious is about is why isnt it GetComponent(foo)

Ill read that for sure

[thorny basalt]

The reason is that it is implied. C# automatically detects the type needed for it.

if you did
MyMonoBehavior fee = GetComponent(foo);
It would work. But if you did
var fee = GetComponent(foo);
It would need a type parameter.

[muted narwhal]

Can I access Inventory from scene on prefab without creating a new one in the prefab itself?

[raw token]

The Inventory is in the scene, and you want something in the prefab to reference it?

[muted narwhal]

Yup

[raw token]

Nope - prefabs can't hold references to anything in a scene.

Ideally, you should assign that reference on the clone when the prefab is instantiated

[muted narwhal]

Could something like this work?

[thorny basalt]

FindObjectOfType is not the best practice.

[muted narwhal]

Yup, I understand, that's only the concept. What would be better to use?

[thorny basalt]

Depends on context

You can have a static variable, and have the inventory assign the variable to itself when it starts. You can have the object create an inventory when it spawns in. Etc.

[sweet sierra]

Hey guys! Hope y'all are doing great. I'm struggling with predicting a trajectory of the game object.

Currently, what's happening is that the trajectory is drawn AFTER the game object moves. I want it to be predicted. The code I'm using for the trajectory is:

public void EstimateTrajectory(Vector2 force, Vector3 startPoint, Vector2 minForce, Vector2 maxForce)
{
    Vector3 velocity = (force / rb.mass) * Time.fixedDeltaTime;
    float flightDuration = (2 * velocity.y) / Physics.gravity.y;
    float stepTime = flightDuration / lineSegmentCount;


    for (int i = 0; i < lineSegmentCount; i++)
    {
        float stepTimePassed = stepTime * i;
        Vector3 movementVector = new Vector3(
            velocity.x * stepTimePassed,
            velocity.y * stepTimePassed - 0.5f * Physics.gravity.y * Mathf.Pow(stepTimePassed, 2),
            velocity.z * stepTimePassed
        );

        points.Add(startPoint + movementVector);
        Debug.Log(points[points.Count - 1]);
    }

    lr.positionCount = points.Count;
    lr.SetPositions(points.ToArray());
}

And I'm calling it in another script like:

tt.EstimateTrajectory(maxPower, transform.position, minPower, maxPower);

Could anyone please help fix it?

[raw token]

Instantiate() returns a reference to what was instantiated. I usually prefer to assign the value on the new clone via that reference, unless I have some specific reason to do otherwise, or it's something handled by events.

[sweet sierra]

Point to be noted is that I'm moving the game object through "Slingshot" or... "Hold To Shoot" mechanism as attached:

[muted narwhal]

So something like this?

[raw token]

Sure that would work. There is a shortcut though...

[muted narwhal]

Would like to hear it

Instantiate() can also take a component on the prefab instead of the prefab's root game object, and then it will return a reference to that component on the clone. So it sort of saves you a GetComponent() call.

public NPCController Prefab;

// ...

NPCController npc = Instantiate(Prefab);
npc.inventory = whatever;

Here I've still dragged the prefab into the Prefab field in the inspector, but instead of referencing the GO it will reference the NPCController component on the GO.

[thorny basalt]

It causes me inner pain seeing you capitalize “Prefab” 🥲

[sweet sierra]

Could anyone help on this please? 😅. I've been stuck for 2 hours now. And now the only issue is the order of the trajectory

[muted narwhal]

Thank you!

[thorny basalt]

Are you using Unity’s built-in physics?

[sweet sierra]

Yes. Mainly vectors, velocity, gravity, and force. that's it

And I don't want the trajectory to display bounces. I only need just 1 curved line as in angry birsd

[raw token]

My naming conventions have been all over the place 😅

But Unity/dotnet conventions both suggest PascalCase for public members, so I've finally given in 🥲

(Even though Unity APIs don't always adhere to that )

[thorny basalt]

I only do mutilators pascal case. But IG public variables having mutilators is uncommon

[sweet sierra]

So, upon logging the force and velocity values. They are correctly collected and obviously the points would be calculated accordingly. But... It's probably not the case when I debug the "points" of the trajectory

They're all the same

[thorny basalt]

Anyway, why are you multiplying the formulas over time if you are doing it as a prediction?

[sweet sierra]

So, the idea is that...

• I pass the force applied on the ball to the function. This is being calculated accurately.
• Using this force, I get the velocity and the time of flight.
• As for the multiplication, well, the trajectory of x axis stays the same over time. Only thing affected is gonna be the y axis. That's where I have used the formula.
• So, whatever point I get, I'm adding it to the points for line renderer and that's it

The start point is the location of the ball from where to start predicting the trajectory

I just noticed I don't even need to pass min or max force as it's already calculated and clamped

Like... in another script, I'm doing this:

if (Input.GetMouseButton(0) && distanceX <= 1 && distanceY <= 1)
{
    Vector3 mousePos = Input.mousePosition;
    mousePos.z = offset;
    currentPoint = cam.ScreenToWorldPoint(mousePos);
    
    
    force = new Vector2(
            Mathf.Clamp(startPoint.x - currentPoint.x, minPower.x, maxPower.x),
            Mathf.Clamp(startPoint.y - currentPoint.y, minPower.y, maxPower.y)
    );

    pt.RenderLine(startPoint, currentPoint);
    tt.EstimateTrajectory(force, transform.position);
}

This script is attached to the same object

So, the trajectory should be calculated as long as the mouse is held. But idk if i'm totally correct. I started 2 weeks ago 💀

[muted narwhal]

After some time of debugging, I roughly understood the problem. I have _itemGameObject, it works great, but once GO moves to another parent - it's just becomes null (still not sure), giving me NullReferenceExecption.
I tried doing something like

            if (transform.childCount != 0)
            {
                var child = transform.GetChild(0);
                if (child)
                {
                    _itemGameObject = child.gameObject;
                }
            }

But it doesn't seems to work

[sweet sierra]

dw about the distanceX or distanceY. They are not related to the trajectory but to the pulling of the ball's mechanism. So, this if statement is triggering just not the "EstimateTrajectory" as intended

[raw token]

Just to be clear, which line in the video is the prediction line?

[sweet sierra]

All of them. I wasn't clearing the points earlier to demonstrate what was happening. If I clear them, the trajectory doesn't form at all because on mouse release, the line is supposed to go away.

Basically, I just want the line to be drawn BEFORE the ball is released, not after which is happening rn 💀

[thorny basalt]

The formula’s in the function use math for the current force that is being applied to the ball

[sweet sierra]

Yes precisely. So, the amount of pull will affect the trajectory.

But... it doesn't 🤡

Start Point is from where I start pulling the ball, and current point is the point where the pull currently is located. Slingshot mechanism tbc

DistanceX and DistanceY are ONLY there to ensure that the pull works only close to the ball, not anywhere else on the screen

[raw token]

Are those prior errors just the same ones over again from you repeating the same interaction?

[sweet sierra]

Well... it's weird that now I multiplied the force by a factor of 5 and... I got 4.01 and 4.02 💀. I'll try a bigger factor to see if trajectory makes up

[muted narwhal]

Yup

[sweet sierra]

Yesss!!

It's working... just in the opposite direction lol

The white line

[raw token]

Okay, cool. Just making sure 👌

I'm not sure I see how these snippets are connected though, or which line is the one the error refers to. Could you post this script on like https://gdl.space?

[sweet sierra]

Also fixed by changing the signs in the point formula

Now, just gotta make sure it lines up with the actual trajectory 😂

[muted narwhal]

Ah

Hey, I'm really new to coding and I have a small problem with the following code:

using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    private Rigidbody2D rb;
    public float Move;
    public float speed;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        Move = Input.GetAxisRaw("Horizontal");
        rb.velocity = new Vector2(Move * speed, rb.velocity.y);
    }
}```
So, I `GetAxisRaw("Horizontal")`, right? And this code works fine, the only issue is that `"Horizontal"` is mapped to `Q` and `D` in the input manager, but when I launch my game, it uses `A` and `D`, I've tried with `"Debug Horizontal"` and it has the same problem. I've tried remapping `"Horizontal"` to `J` and `L` and it worked fine, but `Q` always bugs out and uses `A` while in game, this shouldn't be a keyboard issue as it normally works fine.

P.S. : I'm on an AZERTY keyboard with an AZERTY config.

[wary sonnet]

try turning "Use Physical Keys" on and off

[tender pelican]

Oki

It worked, ty! ❤️

I'm not experienced with drag events, but I'm sort of wondering if like... since the drag handlers are on the inventory slots instead of the item being dragged, if the callbacks are firing on different slots. Like, if you drag the item from SlotA to SlotB, if OnBeginDrag is called on SlotA, and OnEndDrag on SlotB... I'm struggling to find other reasons for a null exception

You might throw some Debug.Log()s in at the top of either method and pass in gameObject as the second argument, so the logs link to their respective game objects, just to check

[sweet sierra]

Need opinion on it lol

Like... it's got a good touch to it? Or I could improve more things

[sharp laurel]

maybe you could chnage ther angle of the camera

[sweet sierra]

That's gonna be up to the UI/UX designer in my team. But.. about the trajectory? The yellow one

I just finished up designing that.. so, what do you think? 😂

[sharp laurel]

pretty good ngl

[raw token]

I definitely like the feedback

[sweet sierra]

😁 🫡

[sweet sierra]

From the trajectory?

[raw token]

Yeah, it makes it feel more responsive 👍

[muted narwhal]

It exists while dragging, then after putting it back into the slot and trying to drag again... bam.

[mint remnant]

maybe add a toggle optoin to see the trails of the trajectory

[sweet sierra]

Coolio! 😀 . Thank you 😄 ! I'll see if I could improve it further and kinda add more juiciness 😋

[raw token]

Wait, what do these Debug.Log() calls look like?

[muted narwhal]

Debug.Log(_itemGameObject.gameObject);

[topaz mortar]

Input.GetKey(KeyCode.LeftControl)
Why is this not getting detected?

[raw token]

Do like

Debug.Log("OnBeginDrag", gameObject);

Debug>log("OnEndDrag", gameObject);

This will add a little link to the log message which will highlight the respective inventory slot GO in the hierarchy. I'm wondering if, for one drag interaction, those game objects might actually be different

[raw token]

Can't say based on that code alone - it looks fine

[topaz mortar]

{
    Debug.Log("Sell all");
    EventManager.StartSellAllItemsEvent();
}
else if (IsHovered && TownController.Instance.InTown && Input.GetKeyDown(KeyCode.S))
{
    SellItem();
}```
My else if triggers properly, my first if doesn't trigger

[muted narwhal]

And then

[topaz mortar]

So if I hold shift and press s, while not hovering an item nothing happens
When I'm hovering an item it just sells that single item, but doesn't show the debug message for selling all

[topaz mortar]

looking at the full code you posted earlier, so not sure if u fixed it
nearestSlotInventorySlot.item = _currentItem;
but you never remove it from the old slot I think?

[raw token]

Huh. Maybe I've forgotten how that second argument works, lol. I'll have to play with that when I have Unity open again. I guess the instance ID might be more useful anyway:

Debug.Log("OnBeginDrag: " + GetInstanceID());

Debug.Log("OnEndDrag: " + GetInstanceID());

Debug.Log("OnDrag: " + GetInstanceID());

[muted narwhal]

Now it has no errors, but item doesn't follows mouse pos

I mean, there's still error on end drag

[raw token]

I think your input stuff looks fine... You make a simple if to test it:

if (Input.GetKey(KeyCode.LeftShift) && Input.GetKeyDown(KeyCode.S)) {
  Debug.Log("Shift + S pressed");
}

[topaz mortar]

Also not sure about this part:

nearestSlotInventorySlot.item = _currentItem;```
You set both to _currentItem, what's the logic there?

[topaz mortar]

damn, github copilot added an ! before my towncontroller check -_- thx lol

[muted narwhal]

item is used for debug by me

just forget to remove it

it's definetly a strange way of debuggin'

but that doesn't really matter

[topaz mortar]

I literally just implemented the same thing for my items yesterday and it gets pretty complicated -_-

[raw token]

Well that's trippy... Sprinkling around some Debug.Log()s shouldn't change the behavior. Did you drag from one slot to another? Could you share the current state of the code again?

[muted narwhal]

No, I mean-

After adding this line

So first I'm making it null

And only then setting the current item

So it's leaves from first slot

[raw token]

Oh sorry I missed that interaction

[topaz mortar]

You would only want to set the original slot to null once the item has been put into the new slot

[muted narwhal]

It is already like that

https://gdl.space/yaroyayune.cpp

[topaz mortar]

nearestSlotInventorySlot._currentItem = _currentItem;```

[muted narwhal]

that's kinda trippy yeah

lemme think

[topaz mortar]

you want to set InventorySlot._currentItem of the OLD itemslot to null AFTER you assigned the item to the new slot

otherwise your inventory would think the item is in both slots

I have this logic on my Item btw, not in my inventory
you're dragging the items not the inventoryslots right?

[muted narwhal]

So just put it in the end of condition?

[muted narwhal]

Yup

[raw token]

I need to go to bed imminently, but my best guess is still that it stems from the drag handling being on the inventory slots rather than the inventory items... If that's true, if you return the code to the state it was in when you could drag items around but keep the Debug.Log()s as they currently are, then the instance IDs which get logged will be different when you drag the item from one slot to another.

And if that's the case, you might consider switching to drag handling on the item rather than the slot. You could keep it on the slot, but I feel like the logic is more complex than the alternative

[sweet sierra]

Ughh guys... I just enhanced my trajectory to display more and...

            tt.EstimateTrajectory(50 * power * force, transform.position);

Why do I have to multiply it by 50? 😭😂

The trajectory is 100% accurately working... lemme show you

But this factor of 50 is kinda weird 💀

[topaz mortar]

https://www.youtube.com/watch?v=BGr-7GZJNXg&t=561s
that's what I used, it explains everything pretty well imo

[muted narwhal]

So it seems like it's kinda... can't get components, since I'm getting the components only at start.

106 and 76 has _itemRectTransform has _itemGameObject respectfully

I don't think that's the case

[muted narwhal]

Mine drag 'n drop system is basically the same

[raw token]

Except his only has the slot handling OnDragEnd and your slots are trying to handle all of the events... I still think you should test the instance IDs 😅

[muted narwhal]

Of what exactly?

[raw token]

Of the slots where these events are occurring #💻┃code-beginner message

My theory is that you start dragging an item, and everything is set and fine. Then you move it over another slot - now that other slot's responsible for OnDrag/OnDragEnd. But that slot doesn't have a _currentItem or a _itemGameObject. It's not at all aware of the item you're dragging, because all of that data is in the other slot alone. So it throws NREs.

[muted narwhal]

I think I already showed you Instance ID's already?

...
Debug.Log("OnBeginDrag: " + GetInstanceID());
...

[raw token]

You did, but only after you simultaneously applied the changes based on what Pasc mentioned, which broke item dragging

[muted narwhal]

Without that one line

[raw token]

Yep

That confirms it

The slot which handles OnDragStart is different from the slot handling OnDragEnd, so they don't have access to the same fields

thus the NREs

[muted narwhal]

How can I fix it then?

[raw token]

Wait I might have spoke too soon - there's two different drag interactions in those logs. 😮‍💨

If the OnBeginDrag and OnEndDrag IDs for one interaction moving an item between two slots match, then I'm wrong.

I think using a script on the inventory item to handle some of these events would simplify things in any scenario, akin to what I assume CodeMonkey does

[muted narwhal]

So basically I can create a drag 'n drop script, and then assign it on the _itemGameObject after creating it?

[raw token]

yeah!

I've got to get to bed though. I'm sorry I wasn't of more help here, and for possibly leading you on a goose chase 🪿

[muted narwhal]

Dw, you pretty much helped me

Thank you!

Godspeed 🫡

[winter tinsel]

i cannot, i simply cannot make this up
same. exact. code.
same. exact. configuration.
the one that changes to sample scene DOES NOT WORk

W H Y

[kindred marsh]

I have this foreach loop, that for some reason breaks at line 31 and says that "object reference not set to an instance of an object"

[winter tinsel]

if i disable the main menu scene it still works from the sample scene, but if i try to move from the main menu to the samplescene the button WILL NOT WORK??

the text isnt a raycast target, the button is activated, the script is right ???

[languid spire]

tilegameobjects is null

[winter tinsel]

wait i might be stupid

[kindred marsh]

It shouldn't be

[winter tinsel]

yeah im stupid nvm, help the other guy

[languid spire]

where to you initialize the List ?

[kindred marsh]

at the top

[teal viper]

If it breaks, can't you inspect all the variables in the debugger..?

[languid spire]

yes, declared but NOT initialized, therefore null

[ivory bobcat]

That would be where you've declare it not where you've initialized it

[teal viper]

And see what is being null

[kindred marsh]

Ahh, how do I initialize it?

[languid spire]

= new()

[ivory bobcat]

= new ...

[kindred marsh]

But the other list works just fine

[ivory bobcat]

You can do so during declaration or in Start etc - in your case during declaration should be fine.

[ivory bobcat]

You've likely populated it from the inspector, implicitly creating a new instance.

[kindred marsh]

Ohhh

[languid spire]

the other list is public, it is initialized by Unity

[kindred marsh]

That makes sense

[winter tinsel]

line 12 in question

im lost

[languid spire]

no object with that tag

[winter tinsel]

the object is in another scene thats currently unloaded

[languid spire]

then how do you expect to find it?

[winter tinsel]

the crazy part is the game works somehow???

[languid spire]

null ref will not srop the game just make pausy unusable

[winter tinsel]

ok well i need to refrence the code inside the object with the tag resume canvas, can i somehow keep it loaded in the same scene?

unload everything else EXCEPT that

[languid spire]

DDOL

[winter tinsel]

huh?

[languid spire]

Dont Destroy On Load

[winter tinsel]

rightt

let me look at that

[ivory bobcat]

Line twelve has a great amount of potential to blow up during runtime. Consider not relying on Find calls but instead: properly reference objects, use Singleton managers and whatnot.

[languid spire]

or at least split the line in 2 and check for null

[zenith crown]

Sorry for late reply, i was asleep and i dont have any other that i recommend. Pixilart is the one i always use 🙂

[winter tinsel]

the only reason i put it there is because my game seems to not work if i load it by loading the scene when the game starts

i deleted the error code and now it works?? but only once?????

ill start in the main menu

start game, game works, ill QUIT to the main menu, start the game AGAIN and this time the timescale is 0???+

nothing in the code that makes it 0

im completely lost

first image is the code that runs at the main menu that sends you to the game, the second one is the button that sends you to the main menu

im stupid wait

fixed?

fixed

[muted narwhal]

I swear to god, I'll see this error in my nightmares;

(DragDrop script, OnEndDrag event)
Debug.Log(Inventory);

why is inventory returning null?

[rare basin]

what's Inventory

where is it declared

and used

[muted narwhal]

[NonSerialized] public Inventory Inventory;

declared in DragDrop script

[languid spire]

I gues you are talking about dragdrop.Inventory, it will be null if slots <= 0.
Also you should not be setting it inside the for loop

[muted narwhal]

I can't set it outside of the loop

There's not one slot in the inventory

[languid spire]

why not?

but it is always the same value irrespective of the number of slots you just set the same thing again and again

and it doesnt get set at all if there are no slots

[rare basin]

why not?

[muted narwhal]

I moved it outside of the loop; now it's setting only for one slot

[muted narwhal]

It's more than 0 slots

[rare basin]

i wouldn't name the variable

the same as your class name tbh

[languid spire]

but you only have one dragdrop

[muted narwhal]

right now - yes.

but there's definetly will be more than one dragdrop

[languid spire]

not based on that code there wont be

[muted narwhal]

I'm still working on the code, there will be

Right now I have a problem

What the hell???

it returns null and not null at the same time

[rare basin]

show the code

[muted narwhal]

https://gdl.space/tedapihinu.cpp

[languid spire]

if that is actually the case then you have 2 DragDrop instances active

[muted narwhal]

i make my object rotate left and right only !Grounded (it's a car) but sometimes it land flipped or by side it's considered Grounded and won't let me rotate how i can change the script from !grounded to !grounded + can rotate when it's not fully grounded like i said (for example it can rotate while it's not fully grounded) idk how to do it anyone ?

[queen adder]

You gotta show the current script

[pastel blade]

if (!isGrounded)

// Rotate around Z-axis when in the air
float airRotateDirection = 0;
if (Input.GetKey(KeyCode.Q))
{
airRotateDirection = 1; // Rotate left around Z-axis while not grounded

Where is grounded being set, also are you usin ChatGPT

[pastel blade]

like that ?

[queen adder]

This way is easier

[pastel blade]

yes i do

grounded is just a square setting layer on the car for it

[queen adder]

ChatGPT is awful at programming unless you intensely guide it

[queen adder]

Probably because the Trigger is thinking the car collider is also ground

[pastel blade]

yes exactly it make bugs alot but i know a bit so i can understand what i'm doing i'm learning ^^

[pastel blade]

yes exactly i think the only way to make script let me fix the car if it land not fully is by making the "if 4 wheel are grounded for each one " idk if there is better way then that

[queen adder]

You have to use layers to exclude the car from being detected

[pastel blade]

like that i can move it forward and backward if grounded and !grounded

[queen adder]

I dont know how IsGrounded is being set so I dont know how to write you an example

And using triggers for ground detection isnt good

CheckBox / Check[Shape] is the better way to do it

[pastel blade]

never used this, can a checkbox let the car only accelerate if it's landed

[queen adder]

Its a bool, true or false, false if the box isnt detecting anything, so you can do anything you want with it

[pastel blade]

but dectecting what exactly ? collision ?

[queen adder]

Yes

[pastel blade]

got it, can you please tell what are the bad thing for this ?

[queen adder]

You can make use layers as well

CheckBox(center, size, rotation, layers, queryTriggerInteraction)

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

[queen adder]

(if Im correct) It can often miss collision detections or something / strange behavior, theres also more code required

ah ok appreciated bro thanks for the information provided it helps

[iron blade]

Hello, how could I make something happen only while the user holds a key down? Right now it only happens once i press it down, but i want it to always happen while i hold it down.

[topaz mortar]

What's an optimal way to structure a "complex" inventory system?
I have different item types, some can be equipped, some can be put in a spellbook, other can be used on item to upgrade them, ...
When you equip an item it is removed from the inventory and put in the equipment
The spells are put in the spellbook instead and also removed from the inventory

Items can be clicked to move or dragged & dropped to inventory/equipment/spellbook if they can go there
Items are generated from combat and loaded from the server on game start

The most complex part is that each itemslot needs to know which item is in it and each item needs to know which itemslot it is in
Items can be dragged/dropped to empty slots or swapped when dragging an item on top of another item
When loading the game I want all items to be in their correct itemslot

My current system is a bit all over the place
I'm creating items in different places and mixing Inventory functions for click with the event system for dragging/dropping 😐

[languid spire]

Input.GetKey

[iron blade]

I did that

[slate haven]

Can someone explain?

[languid spire]

that is correct

[iron blade]

It only moves when i press it down once, if i hold it down it just stays there

[languid spire]

no, debug.log it and see

[iron blade]

it works now,i dont think i saved but i still have a problem

if i walk off my platform is just keeps walking and doesen't fall down

[languid spire]

yes, do you implement gravity?

[iron blade]

yes

i use a rigidbody

[languid spire]

then you should not be moving using transform.position

[iron blade]

oh, then what should i use?

[languid spire]

use the rigidbody methods

[slate haven]

Use Rigidbody Rb in declaration

Then GetComponent in start()

[iron blade]

velocity?

[slate haven]

and use rb.velocity

if u want it to be affected by force use rb.AddForce

[iron blade]

rb.velocity.x = walkSpeed would work?

if i declare rb as a variable

[slate haven]

No

It has to be a vector 3

type

[ivory bobcat]

public Rigidbody rb;//assign it from the inspector``````cs
rb.velocity = transform.forward * speed;```

[slate haven]

inside the vector coordinates, u can write the walkSpeed

[iron blade]

theres no velocity, just angular and linear

[slate haven]

This one works as well

[ivory bobcat]

Unity 6 has probably changed the name to linear velocity

[slate haven]

Also do remember to call rigidBody methods in FixedUpdate ()

Not Update()

[ivory bobcat]

Unity 6 Velocity would be linear velocity: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Rigidbody-linearVelocity.html

[iron blade]

Ooh alr

[iron blade]

okay thanks

it moves at light speed now

[ivory bobcat]

Use a lower value for walk speed

[iron blade]

its 0.1

i gotta use lower than that?

[eternal needle]

odd that you call it light speed, when its basically at 0, 1.5, 0.002

[ivory bobcat]

value/1000f if necessary
