[wintry quarry]

That's pretty vague. Maybe you made a mistake when you tried. Either way you need to debug

[zenith crown]

Would this work?

to cut down on using Move() many times

[rocky canyon]

yes.. u can add them together.. at that point i'd just scale them together too..

Controller.Move((vector1 + vector2) * Time.deltaTime);

thats how I do mine, but up to you

https://www.spawncampgames.com/paste/?serve=code_478 sample controller w/ basic movement + jump

but still needs a custom ground detection solution (and normalized directional vectors)

[zenith crown]

Yeah im gonna make a custom ground detection solution

i might just use the one i already had and fix it

[rocky canyon]

sounds good to me.. i use raycasts in an array but ive seen people use trigger sphere colliders, ive seen OverlapSphere physics calls, https://docs.unity3d.com/ScriptReference/Physics.CheckSphere.html, and sometimes even regular Collisions..

[zenith crown]

Im gonna use a sphere collider

thats what i did in the beginning

[nova swift]

I looked into how Geometry Dash handles input. They use the second method, pooling input every frame, and executing it in one of its physics steps. GD has 240 physics steps, so playing above 240 fps doesn't do anything other than make the game look smoother. Though interestingly, if a tool assisted run is recorded at say 120 fps, it can't be played back at a lower frame rate if an input happens at an uneven point in the lower frame rate, which makes sense, so it's not entirely deterministic per say.

[smoky granite]

hey guys, is there a way i can reference transform in a script? i have no idea where to start and i have no code so far... all i want to do is say if a game object is below 25 on the y axis then do this

[summer stump]

public Transform myTransformReference

You should definitely go through the !learn pathways
Because this is basically one of the most basic things you should know

[frigid quartz]

So I'm googlin' like crazy but I can't find the answer... does it make sense to store a few frequently referenced gameobjects as variables within my gameManager?

[wintry quarry]

Why not

[summer stump]

Sure. Better to store a component type rather than GameObject itself though.

But your question is waaaaay too vague to answer substantially

[smoky granite]

yeah but how can i call that in a script? would i have my puiblic transform be a camera

i do have code so far i lied

hold on

if (Input.GetKeyDown(KeyCode.B))

[frigid quartz]

Like a Transform?

[frigid quartz]

Thanks guys

[summer stump]

If you want the camera's transform, then sure

[smoky granite]

but then i also so && camera is below -25 on the y axis

or something

[wintry quarry]

Like whatever component you're actually interested in

[summer stump]

That is usually better, but you could also use any component (like scripts you have attached)

[summer stump]

So drag the camera object into a field like the one I wrote above 🤷‍♂️

[frigid quartz]

Okay, yeah transforms in my case. Thank you both!

[smoky granite]

but now what?

[queen adder]

why is my my score not adding 1 when i go through the pipes? It works when i use the context menu but not when i hit the trigger collider.

[summer stump]

Definitely go through some basics. This is just standard dot notation. Access the position from the transform if that is what you want. You should absolutely know how to do this before touching unity (as well as how to look up the documentation for properties provided by the Transform component, which I will link in a second)

https://www.w3schools.com/cs/index.php

And then
https://learn.unity.com/pathways

[summer stump]

Here is the transform documentation
https://docs.unity3d.com/ScriptReference/Transform.html

[queen adder]

me?

[summer stump]

No

[rocky canyon]

ahh cool, good research! 👍

[summer stump]

For you, check out the "laws" according to digiholic

The Three Commandments of OnTriggerEnter2D:

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

Could also be the reference though.
Not enough info to say

[cosmic dagger]

You don't have an instance of a Logic script (component) assigned to your PipeMiddleScript . . .

[queen adder]

Yes i know but that is what the code in the first image under void start does

[polar acorn]

Are you getting any errors in the console?

[queen adder]

i think i found the issue, let me have a go at fixing it rq.

fixed it, i didnt have a 2d box collider i just had a box collider, silly mistake.

[cinder crag]

so i got a WeaponsSO scriptableObject that yk acts as the weaponstats and the weaponprefab etc , but im really unsure on how to instantiate the weaponPrefab , i tried it like in the third ss but it didnt work and i tried searching on yt or google but nth so im just stuck tbh , if anyone can help that would be great

[rich adder]

didnt work in what way?

[cosmic dagger]

Check the inspector for a new GameObject, or assign the inatantieted object to a variable and log it . . .

[verbal dome]

And check for errors in the console, firingPoint could throw a null reference exception

[cinder crag]

it doesnt instantiate the weapon at all

[rich adder]

check the above suggestions

[cinder crag]

tried UnityInvaders suggestion , doesnt work

[young lava]

Hi! I had a question about scene management for my game. I am making a roguelike dungeon crawler. Pretty much I am splitting the main dungeon into separate regions, where each region will have 3 floors, which each will have a randomly generated layout. I was wondering if it would be better to have a separate scenes for each floor, or to have a separate scene for each region and simply clear and then regenerate each floor, rather than switching scenes. I'm assuming that there isn't a clear cut answer and that the answer will depend on my needs, but I guess I am wondering if there is an industry standard or better practice as a general rule for scene management situations like this one.

[rich adder]

what do you mean doesn't work ? also screenshot the console

log the instantiation

var instantiatedWeapon = Instantiate(etc..
Debug.Log(instantiatedWeapon, this)

[cinder crag]

this fixed the weapon not instantiating but it doesnt spawn under weaponHolder

[rich adder]

how would this "fix it" its the same exact code

the main difference is storing what you actually spawned and logging

oh i see what happened

[cinder crag]

i guess the code wasnt running cause of the firingpoint not being found so i switched the instantiate and firing point places

[rich adder]

Weapon tag is on the prefab isnt it

[cinder crag]

yeah

[rich adder]

yeah thats not a good way to do this imo. You should've stored that on the weapon itself as a public transform, and retrieve it

but anyway you would need to check the pivot points to ensure they're all correct

[cinder crag]

but what if i wanna make multiple weapons? how do i get the firingPoint of the other weapons

[rich adder]

you store them on the Wapons class

[eternal needle]

How large do you expect these areas to be? Also what is separating a region? If you expect there to be a seamless transition going between regions, scenes might introduce some noticeable lag.

[rich adder]

dont you have a Weapons class that you load the data for ?

[cinder crag]

in the weapons SO?

[rich adder]

no on the weapon that holds the SO

[cinder crag]

weaponShooting script is on the player not on a weapon

[rich adder]

well I would change the Weapon prefab from GameObject to a WEAPON which has other specific things like firepoint etc.

since all weapon will have a firepoint/origin of sorts, even melee can have an origin of a cast

the way you have it works, but its very fragile

[young lava]

If I were to compare it to a top down roguelike, a floor would be around the same size as an enter the gungeon chamber. As for scene transitions between regions I wouldn't really need a very smooth transition, I was planning on adding like a loading screen in between each region.

[rich adder]

cause with a class you can just dofirePoint = weapon.Firepoint

[cinder crag]

so create another script that holds a public Transform firingPoint and put that on any weapon prefab that i make then use that firingPoint from that script and use it as the firingPoint in the WeaponShooting

[rich adder]

yes

that should be what holds the SO in the fire place

[eternal needle]

Havent played that game myself, but yea scenes could be useful then.
If everything is similar enough to the current scene yea you could even just regenerate everything but you'd have to make sure everything resets

[cosmic dagger]

I would move the weapon script to the weapon prefab. It should take care of its own behavior, like shooting, reloading, etc . . .

[safe radish]

for a fluidsystem i'm working on, i also want to add some flowdirections ( seen as red lines between cells here ) theyre pretty easy to figure out if they fall down. but how could i calculate the flow directions on even planes? for now the only info i have is where a plateau starts and where it ends ( ends meaning found a place where water flows down again )

[young lava]

Alrighty sounds good! Thank you very much! ^^

[mint remnant]

should flow equally in all cardinal directions no?

[cinder crag]

i got a question , lets say i make another weapon like a pistol , do i have to make another public SO and put the pistols SO in there or how could i make it so i dont have to make more public SO variables and just use one

[safe radish]

i was thinking from where a plateau starts to where it ends. it could ignore the rest as fluids there should be mostly stagnant. but even with A* i dont think i can set the flowdirections over the width of a river

[rich adder]

yoou create a new SO asset yes but you do not create a new SO class

thats the point of SOs is they are datacontainers that can sit on your project as assets

[cinder crag]

but how i go and instantiate that new weapon whenever i buy it?

[mint remnant]

I guess think of it how real water works, it doesn't know its destination in advance, it just says, can I flow east, west, noth south, if so I flow there, then decide from there if I can flow in them directions next step

[rich adder]

create the weapon as you did now

just swap out the data SO on it, its up to you really

or make the prefabs already have Weapon class hold its appropriate SO

[cinder crag]

i know that , but how do i get the Pistols data SO so i can instantiate the pistols prefab?

[rich adder]

wdym store them inside the script that gives you the said weapon

thats why I just have the weapon prefab already have the SO data inside, either way works.

eg
Weapon[] or WeaponSO[]

this might be harder to figure out with index. You could even use Dictionary to get specific weapon by name

[cinder crag]

ik how to use indexes so i can use an array

[rich adder]

you have to somehow know which index is what weapon

unless you have ofc some field on it you can loop through

[safe radish]

i want to use the flowdirections for a flowmap. so flowing directly into its neighbours isnt really an option. it should ( loosely) follow the path from the highest to the lowest point

[cinder crag]

i know the first index in an array is 0 so the bow will go there and 1 will be pistol then i will just do Instantiate(WeaponStuff[0].weaponSO.weaponPrefab)

[rich adder]

yup, like I said it works, but imo its better to just put the SO data inside the prefabs of weapon already and spawn that instead which includes the whole data

[cinder crag]

weaponStuff is the script that holds the SO and firingpoint btw

[cinder crag]

i alr have it , do i make it into an array orrrr?

[mint remnant]

as long as it's not a huge area, you could probably precalculate it's entire flow in the same manor and in less than a single frame

[hybrid tapir]

How do I make my android keyboard pop up? (this ss is from unity remote app)

[rich adder]

imo you're doing extra class for no reason. i'd make WeaponStuff be the one that does the shooting and had the firerate etc..

[cinder crag]

oh true and also do the instantiating there as well orrr wherever i wanna instantiate that said weapon

[rich adder]

try this
https://docs.unity3d.com/ScriptReference/TouchScreenKeyboard.Open.html

[rich adder]

WeaponSpawner/Store -> Weapon -> WeaponSO

Weapon doesnt need to instantiate anything but the bullets or whatever projectile u got

[cinder crag]

for some reason it doesnt let me drag the WeaponHolder transform into the weaponHolder variable , the weaponHolder is a child of the player

[rich adder]

where did you put WeaponShooting on

if its a prefab you cannot drag scene objects in the weaponholder

weapon holder should already be a transform part of the Weapon prefab

[cinder crag]

did that but my weapon doesnt instantiate for some reason

or should i instantiate it in a diff script?

[wintry quarry]

What do you see in the console when you run this?

[hybrid tapir]

thank you

[cinder crag]

nothing , seems like the code doesnt run even tho referenced it in the start method

[wintry quarry]

If the code isn't running then you didn't attach this script to any active object in the scene

[hybrid tapir]

does unity allow you to put comments on enum selections? im putting one in the inspector window

[cinder crag]

the script is on the object that needs to be instantiated

[wintry quarry]

I think you would have to write a custom property drawer

[wintry quarry]

That doesn't make any sense

[wintry quarry]

this script??

[cinder crag]

yeah

[wintry quarry]

This script is the one that is calling Instantiate

if it's not in the scene

it's not going to run obviously

[hybrid tapir]

ok

how do i mark an enum option as obsolete in a void

or like conditionally preventing it from being selected

[wintry quarry]

A void? You mean a method?

If you don't want a particular option to show in the dropdown you would also write a custom property drawer
Or just remove that option from the enum

[cinder crag]

moved the initvariables method on a script on the player but not sure how to reference the WeaponShooting script from a weapon when its not even instantiated yet

[wintry quarry]

Simple example:

public WeaponShooting weaponPrefab; // assign in the inspector to your prefab

void SpawnWeapon() {
  WeaponShooting weaponInstance = Instantiate(weaponPrefab);
  weaponInstance.Whatever();
}```

Instantiate returns the thing it creates

[hybrid tapir]

im making an enum selection for my method but i wanna make it so when the project platform isnt IOS you cant select one time code

[eternal needle]

what do you mean an enum selection? is this for the user at runtime where they select it?
because in that case theres nothing here about making it obsolete, you just simply dont show them that enum as an option

[cinder crag]

that works nicely but if i want to instantiate another weapon prefab like lets say a pistol , do i have to make another public WeaponShooting weaponPrefab orr

[teal viper]

You could have a list/array of prefabs and instantiate from it by index.

[cinder crag]

ooo thats a good idea thank you

[hybrid tapir]

didnt know putting an enum as a parameter wasnt a thing i could to

why tho

breh the chat suddenly died

[steep rose]

it does that sometimes, dont worry about it to much

[hybrid tapir]

ok

whyd it have to die the moment i asked a question that has no answer online

[steep rose]

dunno

[hybrid tapir]

i wish this wasnt the only good place to ask for help

unity gives me the most false sense of freedom cuz i can never do anything i think about doing

[teal viper]

Because parameters that you can select there have specific editor code written for them.

[hybrid tapir]

oh

[teal viper]

You could write your own editor tool that would display whatever parameters you want, though that's a topic for #↕️┃editor-extensions

[hybrid tapir]

ooo sounds good ig ill check that out

[eternal needle]

chat didnt "die". people just tend not to answer questions that dont make a lot of sense because it becomes a game of trying to figure out what you actually want.
if that unity event was on a script you made, you could also just make a field for the enum on the same script. then use that value selected in inspector rather than making one visible under the unity event.

[lilac ocean]

first time using classes was yesterday, so im still a bit confused. are all variables that arent put in the constructor shared between all instances of a class?

[frosty hound]

Nope

Static variables are shared

[lilac ocean]

ok

[frosty hound]

Whether you set a public or private variable's value in the constructor or not doesn't determine whether its shared. You can skip using a constructor entirely and set the public variables after creating the instance, for example, and it would only be for that instance.

[lilac ocean]

alright thanks

completely unrelated, is there a way you could create a variable through script conditionally and with a name that changes every time one of these variables is created? how would i go about that?

[frosty hound]

What is the actual usecase you're trying to do?

[lilac ocean]

i have a class, every time the user creates a certain type of object in the scene (a 2d circle for example, thats what im using), an instance of this class is created

i just said variable because instances are stored as variables (i think(?))

[eternal needle]

sounds like you just wanna store this in a list/array somewhere

[lilac ocean]

ok yeah, that's a good idea

[ember garden]

I don't get it... pretty much the same thing as this was working yesterday and now suddenly it doesn't.

fireStatus is set to true in OnFire() and the debug message is visible in the log when the event is fired, but it is never read as true in FixedUpdate().... I don't understand this... what am I missing here? This is driving me up the wall.

using UnityEngine;
using UnityEngine.InputSystem;

public class Cannonizer : MonoBehaviour {

    private float rotation = 0f;
    private bool fireStatus;

    void FixedUpdate() {
        if (fireStatus) Debug.Log("HELLO FOR THE LOVE OF F#CK WHYYYYYYY");
    }

    public void OnFire(InputAction.CallbackContext context) {
        if (context.performed) {
            fireStatus = true;
            Debug.Log("OnFire: " + fireStatus);
        }
    }
}

[steep rose]

try to use update and go in debug mode and see if the bool is true

fixed update is used for physics objects, and since this is the only code you provided i can only say this much

also use parentheses for if(fireStatus) in fixed update and you could also test if if(fireStatus == true){Debug.Log("Debugging!")} also helps as well

[frosty hound]

None of that matters

Those two things are the exact same

[mint remnant]

code looks ok to me, add a comment in the code to force a recompile?

[steep rose]

im just suggesting answers i dont have a solution for

[frosty hound]

Which are not helpful

Are you setting your fireStatus to false anywhere, or is this your whole script? (Not trimmed down?)

[ember garden]

It is true, that's what I don't get.

[eternal needle]

then you shouldnt be suggesting anything, what Gindipple said could be valid too. This code simply might not be saved
Or it could be that theres more code we havent seen

[ember garden]

I removed all the other logic, and it's just.. doing this... at least it sounds like there isn't something glaringly apparent

argh

This is kinda crazy

        get { return _fireStatus; }
        set {
            Debug.Log("Setting fireStatus to: " + value);
            _fireStatus = value;
        }
    }```

I think I'm going to call it a night though, because I am pretty much out of patience lol

[ashen trail]

The collision detector is not working, I want the red ball to get destroyed when it makes contact with the players collider but it doesn't.

[deft grail]

are your colliders and rigidbody 2D?
you need to use the 2D Method then

[ashen trail]

my ball has a box collider 2D and a rigidbody 2D

[steep rose]

OntriggerEnter2D

[deft grail]

then you should use what dec_ves said ^

[steep rose]

not OntriggerEnter

[ashen trail]

oh

thank you

[ashen trail]

why doesn't this Instantiate work?

[deft grail]

whats the error

[eternal needle]

after you look at the error, look at the docs for what it expects
https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

there are examples

[deft grail]

you need to use new Vector3(0, 6, 0) instead of directly passing 0, 6, 0

[ashen trail]

THank you, I thought I had tried that earlier but I guess I didn't

[cosmic dagger]

Does the method take floats as arguments? 🤔

[ashen trail]

i'm not sure

[cosmic dagger]

I would check the Unity docs for how to use the method instead of guessing. All the info is there . . .

[ashen trail]

gr4ss already helped me figure out the problem but I will refer to the docs in the future

[mint remnant]

also take advantage of what intellisense shows you

[cosmic dagger]

I know, but learning how to search and find the answer is more important . . .

[ashen trail]

True, I will take a llok at the docs

I first looked at the docs of this but couldn't find an answer, maybe I just don't know how to find answers on the docs or something but I can't find a solution for this.

[mint remnant]

are you sure you're using UnityEngine.Random and not System.Random?

[ashen trail]

how would I know which I'm using?

[mint remnant]

specifically call it out to check, put UnityEngine.Random in place of it

also check your using statements at the top, if you have both used, you'll need to tell it which one you want

[ashen trail]

oh, it works, thank, sorry I'm really new to coding

how would I permanently change it to unityengine.random?

[mint remnant]

you cant really, if you have both using statements required above

[teal viper]

You can do using Random = UnityEngine.Random

[mint remnant]

there might be soem using naming magic you can do, but I don't know it off the top of my head

there, what he said

[ashen trail]

okay thanks

[cosmic dagger]

If you aren't using the System namespace then you don't need the using System statement at the top of the script file . . .

[toxic frigate]

hello all, how do i fix VS compiling issues in unity? in VS i can save changes to scripts fine (as seen here there are intentional errors)

but in unity the compiling loading bar screen doesnt show up anymore and none of the changes carry over

[mint remnant]

tried something as simple as saving and restarting unity?

[devout flower]

Or maybe your computer?

[toxic frigate]

tried both already, but i guess doing it again wouldnt hurt

[mint remnant]

nah probably won't help if didn't the first time

[toxic frigate]

well it did something different this time, which is weird

[devout flower]

Oh weird

[toxic frigate]

i got kicked into safe mode and it looks like the errors got caught by unity along with some other weird ones

but i fixed the code in question and i am still in safe mode, it still doesnt compile

[devout flower]

Is it the last two errors

[mint remnant]

try reimpoting assests, as the error seems to point there

[toxic frigate]

i dont know

[toxic frigate]

how do i reimport assets?

oh uh

[mint remnant]

shot in the dark hree, maybe try uninstall/reinstall Unity as it doesn't look good

[toxic frigate]

that wont delete my project right

[mint remnant]

project would be saved seperately

but if your project file is somehow corrupeted, you might re-encounter the issue

[toxic frigate]

if it is corrupted how would i fix it

[mint remnant]

that I haven't a clue, but try the reinstall would be my first thought. Oh and in the assests panel right click and there is options for reimpot and reimport all, if it ends up to be a bad assest

[toxic frigate]

that would do it

[muted narwhal]

I have a prefab with script in it, and I also have 2 parents to prefab generate in it. Basically, when prefab generates, in parent one (InventoryPanel) Context Menu script is set up, but in parent two (HotbarPanel) it's not set up, giving me NullReferenceException

Why is this happening?

[mint remnant]

isolate the line that has the null reference with debug statements, check each item in any item.subitem.whatever progressively, that will at least tell you exactly what part it is finding as null

[muted narwhal]

It's finding Context Menu null

it setups in Inventory Panel:

But not in Hotbar Panel:

Is there a way to consolodate a RPS based thing without having 7 if conditionals?

            if (inter.value == random){

            }

            if (inter.value == 3 && random == 1){
                Debug.Log("lose");
            }```

[wintry quarry]

Why 7 conditions? You only need 3

[spiral glen]

I got it

mb

var result = (inter.value, random) switch {
(1,3) or (2,1) or (3,2) => "win",
(1,2) or (2,3) or (3,1) => "lose",
_ => "tie"
};

👍

I even learnt what a tuple was

[wintry quarry]

if (a > b)
else if ( b < a)
else```

[eternal needle]

looks like chatgpt

[spiral glen]

the top one or my second result

[wintry quarry]

Nope this is overcomplicated too

[eternal needle]

the one with the switch

[spiral glen]

aw

I asked on a different discord for advice to condense it and they said to try tuples

[wintry quarry]

All you need is something like this @spiral glen

[spiral glen]

also this wouldn't work since 1 is rock, 2 is paper, 3 is scissor

it's not that bigger number == win

I prolly should of specified mb

[wintry quarry]

Probably better to use an enum then for readability

Also your first example should have been else ifs

[spiral glen]

I know I fixed that after I put it up

what's enums?

couroutines?

how does that help

[raw token]

no one mentioned coroutines 👀

[eternal needle]

did you google enum c#?

enumerator is different

[spiral glen]

I googled enumerator unity

[void thicket]

enum is different thing

[wintry quarry]

Also this would work mathematically with no switches or tuples

int rock = 0;
int paper = 1;
int scissors = 2;

// return 1 for a win, 0 for tie, -1 for loss
public int EvaluateGame(int me, int you) {
    if (you == me) return 0;
    else if (you == ((me + 1) % 3)) return -1;
    else return 1;
}```

[spiral glen]

I feel like that's complicating it more then the tuple

[wintry quarry]

feels simple to me, definitely more efficient

[eternal needle]

you should definitely go with a solution that you understand, and i highly doubt you fully understand switch statements

[void thicket]

You could use pattern matching to be fun 😄

[spiral glen]

I kinda understand the switch statements

or atleast it looks like it would make sense

[eternal needle]

unless you've learned them outside of here, no you dont

[eternal needle]

#💻┃code-beginner message

for each of my (x,y)

i feel like you're just looking at the (1,3) pointing at the "win" and going entirely based off that. Pattern matching is more than just that

[spiral glen]

I am 100% ngl

[void thicket]

I mean if you make rock-scissors-paper-lizzard-spock you’d think different way

[spiral glen]

I would but I'm not so it's all good

I can't really find any resources on tuples so I'm just assuming off what someone else told me btw

[eternal needle]

exactly why you should stick to the solution that you fully understand

[spiral glen]

yeah but that solution is like 10+ lines

and I somewhat get this answer

[raw token]

For overly verbose funsies with a dictionary of questionable utility,

public enum Strategy {
  Rock,
  Paper,
  Scissors
}

private Dictionary<Strategy, Strategy> strategyCounters {
  { Rock, Scissors },
  { Paper, Rock },
  { Scissors, Paper }
};

public int EvaluateGame(Strategy me, Strategy you) {
  if (me == you) return 0;
  if (strategyCounters[me] == you) return 1;
  return -1;
}

[eternal needle]

So? are you printing your code out and this so happens to use an extra page?
it makes 0 difference, and you know that the other solution is above what you know

[spiral glen]

It makes me sad

but fine, I get what you're saying

[muted narwhal]

Bump

[raw token]

It's really not clear what you're describing... I don't understand what you mean by "I also have 2 parents to prefab generate in it." A picture of the relevant hierarchy might help

[raw token]

This is the hierarchy of the prefab in question?

Or the scene?

[muted narwhal]

Scene

These are two parent, the prefab generates in InventoryPanel 'n HotbarPanel

The problem: prefab has no script set up when generating in hotbar panel

but it has script set up when generating in inventory panel

[raw token]

Just to be absolutely clear, I think you're saying you instantiate two clones of the prefab, one as a child of the InventoryPanel GO, and the other as a child of the HotbarPanel GO?

[muted narwhal]

Yup

They're not GO tho, just an empty.

[raw token]

An empty GO is still a GO 🙃 . But noted 👍

[raw token]

I'd think to verify that inventoryPanel is assigned to what you think it is in the script which instantiates the prefab into the HotbarPanel... it seems like inventoryPanel.GetComponentInChildren<ContextMenu>() may be failing to find a component and returning null as a result

[muted narwhal]

You see, when I'm making it like this it works, so there's definitely something wrong with parent, but what exactly? 🤔 It is exactly the same as Inventory Panel

Hotbar Panel and Inventory Panel

[raw token]

Wait...

So ContextMenu is a component within the InventorySlot prefab?

[muted narwhal]

Yeah

[raw token]

Is the code which instantiates the prefabs in the same method/class?

[muted narwhal]

The same class, but different methods

But they're both called on Start

[raw token]

Is the hotbar one called first?

[muted narwhal]

Yup

[raw token]

That's the problem. It's trying to lookup that ContextMenu component within InventoryPanel - but it doesn't exist yet

[muted narwhal]

Oh, thank you!

[hybrid tapir]

keyboard = TouchScreenKeyboard.Open("", TouchScreenKeyboardType.NumberPad);
only opens up default on my android

[topaz mortar]

{
    await CloudCode.SaveGame(Character, InventoryData);
}```
Would this actually wait for SaveGame before closing the application?

Okaj so I have one script that is calling OnApplicationQuit and another script that is not calling it?
Both are in my scene? Copy/pasted the function from one to the other and it works in the 2nd one?

[wintry quarry]

I don't think there's any indication in the docs that OnApplicationQuit is allowed to be async

It seems quite unlikely to me that it could be...

[teal viper]

Even if it was, since it's async, the app wouldn't wait for it to finish and just quit before the save is complete.

[edgy forge]

I'm having a weird problem. I have a gameobject that I've SetActive(false) to hide it, but after I show it again it can't be found. also, it doesn't show it again.

    public static IEnumerator ShowBlocker()
    {
        Debug.Log("Blocking screen");

        GameObject.Find("Blocker")?.SetActive(true);
        yield return new WaitForEndOfFrame();
    }```
```cs
    private static IEnumerator DownloadDependenciesAndLoadScene(string storyName)
    {
        yield return Blocker.ShowBlocker();
        var textMeshProComponent = GameObject.Find("ProgressText").GetComponent<TMPro.TextMeshProUGUI>();

progressFillObject is a child gameobject of Blocker but it's null

is it maybe my yields? the blocker isn't reactivating and becoming visible again

[topaz mortar]

Find() only returns active gameobjects

[edgy forge]

aha

so I should find it once and store it?

is there a way to find inactive objects?

[topaz mortar]

that is an option

[edgy forge]

FindObjectsOfType should do it

[topaz mortar]

https://docs.unity3d.com/ScriptReference/Resources.FindObjectsOfTypeAll.html
But probably not a great idea

[eternal needle]

ideally you shouldnt even be using find, and i dont think GameObject.Find specifically can find inactive objects (from a quick look at the docs).
also you shouldnt be using ? on unity objects, https://docs.unity3d.com/ScriptReference/Object.html

This class doesn't support the null-conditional operator (?.) and the null-coalescing operator (??).

[topaz mortar]

possible, but probably not a good idea

just store it somewhere if u need it again later

[edgy forge]

cheers

findobjectsbytype is just going to return literally all gameobjects isn't it

so yeah I'll just save it in a static

[lost hamlet]

It's pretty useful for a few things (mostly modding but there are some uses for your own game)

Especially once you couple it with LINQ

Tho it's only useful if you call it once

Or only at specific times

[topaz mortar]

I have an Inventory script with a private _itemSlots Dictionary that tracks which item is in which itemslot
For dragging and dropping, my ItemSlot script needs access to the ItemSlots variable
What's the best way to make this available?
ItemSlot is a script on a prefab, so I can't make a direct reference to my inventory gameobject

I could search for the Inventory script in parent Inventory inventory = droppedItem.GetComponentInParent<Inventory>(); on Start and just save Inventory for each ItemSlot?

Or I could just set the Inventory when creating the ItemSlots, which happens in my Inventory script

[gleaming kraken]

why would anyone use c# events over unity events?

• Unity Event: Make the event, connect it to a function in the editor, and then fire the event.

• C# Event: Make the event, choose a delegate, create a class for EventArgs (if any), connect the event to a function, then fire the event.

it just seems more complicated than Unity Events honestly

[topaz mortar]

because you want events on things not yet in the editor?
like items being instantiated at runtime from a prefab?

[gleaming kraken]

fire an event when instantiating the item.

if that's what you mean

[timber comet]

Hey guys, it’s better (for optimisation) to check if you are near a certain type of object, by: saving their position at the start of the game with some delegate or something like that and then check it by using .Distance every 0.5s in a Courutine or do a physics.SphereCast (or BoxCast) and do this physics every 0.5s in a courutine (in the player script)? Context: I need that when the player get near some objects (I have an interface and a raycast that works when I press “E”), some Ui element needs to appear near that object (they can be more than one near each other, but they shouldn’t change position during the game)

[eternal needle]

It sounds odd that your items are children of an inventory. Tbh the above is hard to answer without knowing the relationship between item slot and inventory. ItemSlot also needing a reference to the dictionary sounds backwards. Maybe reconsider the structure here.

[eternal needle]

EventArgs typically isnt used in unity, and listing "choose a delegate" as a step is really kinda silly. It's about the same effort as choosing which data type to store a number in. This being listed makes me think you got this list of steps from chatgpt tbh
Anyways you typically use unity events if you want something serialized in inspector. C# delegates do let you pass in a lot more parameters though tbh I've rarely ever used more than 4.

[gleaming kraken]

Understood, thanks.

[sage mirage]

Hello, guys! So, I have a small issue here with my character rotation. So, I have made a respawn system for my player and when I click home button it's respawning at the position I want it to respawn. The only issue is that when it's respawning, it doesn't rotate my character and camera to view the center when I replay the game. Check the video!

I have tried to use Quaternion on my Respawn Function but it doesn't work.

    {
        transform.position = spawnPoint.position;
        transform.rotation = spawnPoint.rotation;

        if (characterController != null)
        {
            characterController.enabled = false;
            characterController.enabled = true;
        }

        if (animator != null)
        {
            animator.Rebind();
            animator.Update(0f);
        }
    }```

spawn point has the rotation that I want my player to have, so that's why I am using the spawn point rotation

I have tried also this one but didn't work.

transform.rotation = Quaternion.Euler(0, -90f, 0f);

I have tried also to respawn my player with SceneManager like to reload the scene but I am not sure if it's an efficient way to make respawn system, but that way my character is respawning properly and rotated properly.

[timber comet]

There’s only one spawn point or there are multiple of them?

[sage mirage]

No there is only one spawn point and my player is respawning at the position.

I want my character when I click play to see the computer from the camera not like you saw in the video

[timber comet]

Got it, the rotation of your spawn point may be different from the rotation of your player

At the start, your player is already spawned in, so it is using its own rotation

After respawning its using spawn point rotation

[topaz mortar]

this works but ... eh? any better suggestions?
droppedItem.DragStartParent.parent.GetComponent<Inventory>().ItemSlots[droppedItem.ItemData.InventorySlot].GetComponent<InventorySlot>().CurrentItem = null;

[timber comet]

You should check the rotation of your spawn point during runtime

[sage mirage]

Alright!

[topaz mortar]

I only use it once though, so probably not an issue?

[timber comet]

It’s burning my eyes

[sage mirage]

I am pretty sure it's not that because I ve checked it right now and spawn point rotation doesn't change at all.

It's 0, -90 and 0

[timber comet]

Yeh, I mean maybe the initial rotation is wrong?

[sage mirage]

I want it to be at the values

at these

[timber comet]

Try changing some values

Just to test

So you can see if your initial rotation is correct at least

[timber comet]

Anyone that have a solution for this?

[copper matrix]

what does that mean

[wintry quarry]

You're trying to call SetActiveScene on the DDOL scene

which isn't allowed

[copper matrix]

whats a ddol scene

[wintry quarry]

It's the scene that DDOL objects live in

You might have done SceneManager.SetActiveScene(someObject.scene); where someObject was DDOL

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[copper matrix]

3 scripts 2 of them are from unity itself

and this is mz scipt

[wintry quarry]

I mean, seems like you're just guessing

why not just look at the full stack trace of your error

it will tell you the source of the problem right there

[wintry quarry]

this screenshot screams to me that you don't even have your console window open?

1. Open the console window
2. click on the error
3. observe the full stack trace and see where it's originating

[copper matrix]

Its gone btw

i just cleared console and it never came back

[wintry quarry]

likely an error in a Unity editor script

reading the full stack trace if it reappears will tell you

[sage mirage]

Btw, I found the solution to the problem. It was related with how I am rotating camera on my other script, so it's fine now.

[iron steeple]

Okay im a bit confused i made a jump using character control but it seems that the initial jump its make the jump look kinda weird but when it goes down it just curved how is it like that

public class test : MonoBehaviour
{
    CharacterController CC;
    float gravity = 9;

    private void Start()
    {
        CC = GetComponent<CharacterController>();
    }

    private void Update()
    {   
        // Jump isnt arc curved
        float Ymove = gravity * Time.deltaTime * 10;
        float Xmove = Input.GetAxis("Horizontal");
        float Zmove = Input.GetAxis("Vertical");
        Vector3 CombineMovement = new Vector3(Xmove + 1, -Ymove, Zmove);
       
        Debug.Log(CombineMovement);
        // when player jump
        if (Input.GetKeyDown(KeyCode.Space))
        {
            CombineMovement.y = 100;
        }
        else
        {
            CombineMovement.y =- gravity * Time.deltaTime * 10;
        }
        //note -2 in the new vector is gravity it constantly make it go down + 1 is when it move forward

        CC.Move(CombineMovement * Time.deltaTime * 10);

    }
}

[iron olive]

    void Health() 
    {
        if (Input.GetKeyDown(KeyCode.V)) 
        {
            animator.SetBool("Damaged", true);
            health = health - damage;
             
            animator.SetBool("Damaged", false);
        }
    }

damaged is a bool that is linked to an animator. when the bool is true, the hurt animation plays. how could i make a wait so the animation stays for half a second?

[silk night]

Do you have a rigidbody on your character that drags it down through gravity?

[silk night]

2 ways:

• Make a coroutine with yield return new WaitForSeconds(0.5f)
• Add an event to your animation that triggers a function that sets the bool to false

[iron steeple]

No rigidbody only charactercontrol

[silk night]

But as it sounds like damaged is a looping animation shorter than 0.5s?

[iron olive]

its 2 frames

repeating

[wintry quarry]

You're always stating with some constant value basically for y velocity... not maintaining any of the velocity frame to frame

float Ymove = gravity * Time.deltaTime * 10;```

[iron olive]

do i use IEnumerator?

[wintry quarry]

See^

[silk night]

Yes, that would be the Coroutine function definition, look up coroutines and the WaitForSeconds stuff, its easy to understand

[iron olive]

alr

[iron steeple]

i deleted the float ymove

so my code is like this

[languid spire]

I'm guessing this should be -= not =-
CombineMovement.y =- gravity * Time.deltaTime * 10;

[wintry quarry]

This^ but also yMove needs to be a field not a local variable, so it can store information between frames

[iron steeple]

CharacterController CC;
float gravity = 9;

private void Start()
{
    CC = GetComponent<CharacterController>();
}

private void Update()
{   
    // Jump isnt arc curved
    float Xmove = Input.GetAxis("Horizontal");
    float Zmove = Input.GetAxis("Vertical");
    Vector3 CombineMovement = new Vector3(Xmove + 1, -gravity, Zmove);
    CC.Move(CombineMovement * Time.deltaTime);
    Debug.Log(CombineMovement);
    // when player jump
    if (Input.GetKeyDown(KeyCode.Space))
    {
        CombineMovement.y = 10;
    }
    else
    {
        CombineMovement.y =- gravity * Time.deltaTime * 10;
    }
    //note -2 in the new vector is gravity it constantly make it go down + 1 is when it move forward

    CC.Move(CombineMovement * Time.deltaTime * 10);

}
``` still the same result

[wintry quarry]

because you're still doing the same thing:

Vector3 CombineMovement = new Vector3(Xmove + 1, -gravity, Zmove);```

you're not storing any information between frames

[iron steeple]

how do i do that

[wintry quarry]

in a variable

float yVelocity = 0;

void Update() {
  yVelocity -= Time.deltaTime * gravity;
  Vector3 CombineMovement = new Vector3(Xmove + 1, yVelocity, Zmove);
}``` for example

Also you should only be calling CC.Move ONE time

not twice

[iron steeple]

didn't that do that?

[wintry quarry]

no you didn't do that

You did this Vector3 CombineMovement = new Vector3(Xmove + 1, -gravity, Zmove);

-gravity is always the same number

-9

[iron steeple]

isnt this the same as well?
float Ymove = gravity * Time.deltaTime * 10;

[wintry quarry]

no

it is not the same

none of your examples have even attempted to try to store the y velocity between frames

again you need a member variable/field to do that

[iron steeple]

man its been 1 day of coding why is it so hard

[wintry quarry]

you're not thinking through what your code is doing step by step

Think about what the values of all the variables will be at each step, and do that exercise over the course of a couple of frames

then it will make sense

[iron steeple]

bro i even drew why is it like having the problem but couldnt figure out how to make it like the one i sketch

[wintry quarry]

and/or you're not understanding one or more bits of the code

not sure what you mean by sketch

but your code doesn't match how gravity works naturally

[iron steeple]

idk man

i feel so tired of this

[wintry quarry]

frustration is extremely common when learning to code

some people get over that hump, many do not

coding is not for everyone

¯_(ツ)_/¯

[iron steeple]

i have been coding python for 3 years and i still get it but this

this is just a whole nother lvel

[languid spire]

there is no difference between logic in Python and logic in C#

[iron steeple]

yeah but we talking about in c# in unity

c# it self i get it

[languid spire]

no difference C# is C#

[iron steeple]

but in unity is weird

[iron steeple]

but its in unity

[languid spire]

so what, Unity is an API just like .Net or anything else

[wintry quarry]

nope it's normal C#

[iron steeple]

your telling me c# normally i use is the same c# in unity bro i dont even know half of the stuff in unity

[wintry quarry]

if you get C# you will understand the difference between a local variable and a field

[languid spire]

that is because you have made little attempt to understand the API, Python exists on external libraries, the concept is identical

[iron steeple]

that means c# in visual studio is not the same c# in unity because it uses an api for unity to connect to c#

[languid spire]

not at all, the Unity API extends C# in the same way that the ,Net API extends C#

also the same way you can extend C# by writing your own libraries, exactly like Python

[iron steeple]

not sure this will help me in my current state of coding a projct in unity tho

[languid spire]

I don't see where your problem is, Python has the concept of scope (using indentation) C# also has scope (Using {}), Different syntax but the concept is identical

[vital terrace]

Hi I am making a VR game and I am using XR toolkit and I want to make it so that when the user points to an object and clicks the A button, some text will show up but I have no idea how to do it and I couldnt figure it out

[teal viper]

Truth is most people bragging about coding X years in programming language Y, yet struggling with new language basics, probably never actually gained any expertise in that Y language. For whatever reason.

[queen adder]

using UnityAPI

void Function()
{
    Destroy(gameObject) <--- A part of Unity API
}

void Function()
{
    Destroy(gameObject) <--- Not using Unity API so this function doesnt exist
}

[iron steeple]

btw

the jump still weird

when the objeect goes up

its instantly goes up there but as in not making a curve

[stuck palm]

anyone know if it is possible to do something like this with debug gizmos?

like adding dots and numbers

[wintry quarry]

you'd have to show your new code

[zenith cypress]

Dots can be Gizmos.DrawSphere and numbers can be Handles.Label and you would need them in one of these functions to render https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnDrawGizmos.html

[wintry quarry]

^ exactly what I was going to say

[cinder crag]

so im trying to switch the sprite so it switches rotation based on what direction its looking but for some reason it doesnt switch the sprite and it goes to the other way so im not sure what to do tbh

[willow scroll]

You should consider using the SpriteRenderer.FlipX and FlipY methods, first of all

[hexed terrace]

You would also need to flip Y, not just X.

Though look into what sashok suggested

[cinder crag]

seems like i only had to flip Y

[cinder crag]

that worked but it only flipped my sprite so i jsut used transform.DOScaleY() from DoTween since it looks funny lol

[queen adder]

 Invoke("ResetGun", shootCooldown); //Sets CanShoot bool to true

Is this sort of approach to cooldowns bad?

[frosty hound]

Yep

What if you want to reset it immediately, or adjust the cooldown at any point?

[queen adder]

Well is there any other issues to that, like frame rate dependecy or whatever

    public void DoRecoil()
    {
        targetRot += new Vector3(recoil_X, Random.Range(-recoil_Y, recoil_Y), Random.Range(-recoil_Z, recoil_Z));
        targetPos -= new Vector3(0, 0, zKickBack);
    }

Should I be deltaTiming these? The recoil is more intense with VSync off

[timber comet]

Anyone?

[polar acorn]

The Physics check and cast methods are stupidly cheap. You should basically never worry about using them for performance reasons, and if you do, there's NonAlloc methods that get rid of the only thing of theirs that does take time, the allocation of new variables

[raw token]

Then it sounds like "yes," but we'd need to know where/when you're calling this method.

In general, anything which should occur over time should factor in time

[queen adder]

DoRecoil is called one time per shot, the Lerps are handled in Update with proper deltatime

With 0 shot cooldown, its very noticable, not so much with proper cooldowns

[timber comet]

Ok, Thank you

[stuck palm]

how can i make this render the points in a clockwise way? right now its rendering them coutner clockwise.

[fluid kiln]

how do i make in a 2d game a specific tileset block not passable by the player ?

Are you referring to UnityEngine.Tilemaps?

idk if i did this right but

[fluid kiln]

yessir!

[willow scroll]

There is a TilemapCollider2D component, does this information help you?

[stuck palm]

its still rendering them in a counter clockwise way

actually, i think the problem is where i've placed the points themselves

[fluid kiln]

uhmm how do i acess it? i can only find normal tilemaps

[willow scroll]

It appears when adding component in the Inspector

[fluid kiln]

tysm!

my character isn't colliding, is it an issue with my movement script?

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public Stat speed;
    public Rigidbody2D rb;
    public Animator animator;
    public bool canMove = true;

    Vector2 movement;
    Vector2 lastMovement;

    void Update()
    {
            movement.x = Input.GetAxisRaw("Horizontal");
            movement.y = Input.GetAxisRaw("Vertical");

            if (movement.magnitude > 0.1f) // Player is moving
            {
                lastMovement = movement; // Update last movement only when moving
            }

            animator.SetFloat("Horizontal", movement.x);
            animator.SetFloat("Vertical", movement.y);
            if(canMove){
                animator.SetFloat("Speed", movement.magnitude);
            }
            if(!canMove){
                animator.SetFloat("Speed", 0);
            }
            animator.SetFloat("IdleHorizontal", lastMovement.x);
            animator.SetFloat("IdleVertical", lastMovement.y);

            if (canMove)
        {
            Vector2 currentPosition = transform.position;

            currentPosition.x += movement.x * speed.GetAmount() * Time.deltaTime;
            currentPosition.y += movement.y * speed.GetAmount() * Time.deltaTime;

            transform.position = currentPosition;
        }
    }

}

[willow scroll]

When dealing with physics, you do not changing the Transform.position properly directly

[rocky canyon]

yes

[willow scroll]

Instead, this whole code in FixedUpdate and use a suitable Rigidbody method

[fluid kiln]

tysm!

[willow scroll]

Note that not all Rigidbody methods detect collisions properly

[fluid kiln]

ill try ! i remember not liking fixed update because it made the camera following the player "shaky" and less smooth

idk how to explain it

[willow scroll]

I get it

It may happen

[willow scroll]

Just note that everything related to physics goes in FixedUpdate

[rocky canyon]

you could couple ur movement w/ cinemachine (it has interpolation methods built in) that can help

[willow scroll]

Camera movement goes in LateUpdate

Otherwise in Update (or OnGUI etc.)

[fluid kiln]

tysm! if i have more to ask ill do here <3

[stuck palm]

does a polygon have equal sides as vertices?

[frosty hound]

Take a pen and paper, draw some points, connect the dots, count?

[fluid kiln]

i did everything you guys told me but now when i press play my tilemaps disappear

if i turn of isSimulated from my player it doesn't disappear anymore but i can't WASD

This is my player movement, i created a tilemap, drew the borders of my map and attached a tilemap collider to it

[willow scroll]

Are any errors thrown?

[fluid kiln]

no, just when i hit play my tilemap disappears

[willow scroll]

Any Tilemap references in your code?

[fluid kiln]

nope! its just there for deco/ colliding purposes

[willow scroll]

Please, show the console when the issue happens

[fluid kiln]

oh, its throwing me this error now

Pretty sure it was being thrown before too.

[fluid kiln]

i think i just noticed then sorry x.x

[willow scroll]

This looks like a Unity bug, consider reloading Unity

[fluid kiln]

yes it disappeared

but i still have the issue

[willow scroll]

Still errors?

[fluid kiln]

no errors but when i play and the player rigidbody "is simulated" is on the tilemap disappears

and if its off i can't wasd

[willow scroll]

And errors are not disabled by you, right? Please, show the whole Console

Also, please, show your Rigidbody

[willow scroll]

Yes, make a condition out of it

if this is the bed AND gotosleeptext is active

[fading seal]

im a little confused

[willow scroll]

What exactly confuses you?

[fading seal]

is this supposed to equal what you said above?

[willow scroll]

Not sure what you mean

[fading seal]

nevermind lol ill figure it out

[willow scroll]

And this thing becomes not simulated?

[fluid kiln]

no but if i turn it not simulated it stops the movement from working and also makes tilemap not disappear

[toxic frigate]

unfortunately after uninstalling and reinstalling this issue still persists

i honestly have no idea what is going on, this is quite frustrating for me, does anyone know how to uninstall and reinstall visual studio for unity

[river quiver]

when checking for input should i put the if statement in the Update() or FixedUpdate()

or it doesnt really matter

[polar acorn]

Input should always be in Update

[stuck palm]

how can i make it so the entity position updates the actual unity transform in the editor while im not in play mode?

[river quiver]

ty

[frosty hound]

You can use the ExecuteAlways attribute so that code runs in editor:
https://docs.unity3d.com/ScriptReference/ExecuteAlways.html

[stuck palm]

couldnt that possibly be unsafe?

[frosty hound]

In what sense?

[stuck palm]

like if the update code has some sort of simulation it just does the simulation anyway

[frosty hound]

And why would that be "unsafe"?

[stuck palm]

i dont want it to simulate, i just wnat to chagne positions

and i just realised i can do application.isplaying for editor specific thigns

[frosty hound]

So just change the position in the Update function when in edit mode.

Yes, the example in the docs shows exactly that

Otherwise, if you don't want it to run all the time, you could make an editor button for SyncTransform that just aligns it with the position property.

[stuck palm]

this seems to work fine. thanks!

private void Update()
    {
        if (Application.isPlaying)
        {
            return;
        }
        transform.position = fTransform.position;
    }

is there any way to override the actions of the arrows?

[wanton kraken]

getting the problem of "not all code paths return a value" but i don't want the method to work under certain conditions, how do i avoid this?

    public GameObject AddBullet(GameObject NewBullet)
    {
        if(Bullets[0] == null){
            Bullets[0] = NewBullet;
        } else if(Bullets [1] == null){
            Bullets[1] = NewBullet;
        } else if (Bullets [2] == null){
            Bullets[2] = NewBullet;
        } else{
            return null; //I want this to not work if all three slots are occupied
        }
    }

[wintry quarry]

you need to define what you mean by "not work"

that's why the compiler needs you to write some code there

what does "not work" mean

[wanton kraken]

this method is for checking if there's room to add a new bullet to the list. if all slots are occupied, i don't want it to do anything

[wintry quarry]

Why does your function have a return type

since you have given your function a return type, you must return something (a GameObject reference specifically)

do you need that return value? Are you doing something with it?

If you don't need your function to return anything, you should be using void as the return type instead of GameObject

[wanton kraken]

i see, that gameobject NewBullet is supposed to be a parameter. so on collision, the powerup can call this method, and if it clears out, the bullet can be added by the list (bullet is selected by RNG in the powerup's code so it's a parameter when calling it)

ahhh i see

[wintry quarry]

The parameter is on the right in the parentheses.
The first GameObject you have here is a return type

[wanton kraken]

that should solve it then

[wintry quarry]

it should be void if you don't want to return anything

[wanton kraken]

just void AddBullet(GameObject NewBullet)

thank you, friend!

[wintry quarry]

yes

you can just delete the last else {} part entirely after that

[sleek marten]

I've got this code here that shoots at the position of my enemy object

    {
        // Instantiate the bullet prefab at the player's position
        GameObject bullet = Instantiate(bulletPrefab, transform.position, Quaternion.identity);

        // Set the direction of the bullet towards the target enemy
        Vector2 direction = (targetEnemy.position - transform.position).normalized;
        bullet.transform.right = direction;  // Assuming bullet moves along its local right direction

        // Optionally, you can set the bullet's speed in its own script
    }```

I tried altering the code so it fires 3 bullets in a fixed pattern

    {
        // Calculate the direction to the target enemy
        Vector2 direction = (targetEnemy.position - transform.position).normalized;

        // Fire three bullets in a spread pattern
        for (int i = 0; i < 3; i++)
        {
            // Calculate the angle offset for each bullet
            float spreadAngle = (i - 1) * bulletSpreadAngle;

            // Calculate the rotated direction for each bullet
            Quaternion bulletRotation = Quaternion.Euler(0, 0, spreadAngle) * Quaternion.LookRotation(Vector3.forward, direction);
            GameObject bullet = Instantiate(bulletPrefab, transform.position, bulletRotation);

            // Optionally, set the bullet's speed or any other properties here
        }
    }```

it does the spread correctly, but it's not shooting at the enemy object

it tries to aim anywhere BUT the enemy and I really don't understand why

I've gone down my scripts and I've isolated the problem to this section. does anyone have ideas what I'm doing wrong?

[river quiver]

is there a way to round a number to the second decimal place? cause in Mathf() docs i only found .Round() which gives you number rounded to the nearest integer

[languid spire]

nothing built in, you would need to code it yourself

[upper forge]

Is anyone avaliable to get in call and help me with collecting an abject and spawing it, then being able to drag it in a position and if its the correct position it stays and if not it returns bad to orginal positiion?
Im getting so twisted and turned around on this...

[rich adder]

not likely someone is going to take the time to be in a voicechat call.
Read the #854851968446365696 to how to post your issue

[wintry quarry]

For what purpose? Just for displaying?

[desert temple]

Working on a Brick Breaker game for a class. Running into an issue, where I'm trying to have the ball reset at the paddle when it goes out of bounds. From my Debug, I know it is triggering the box collider below, so that's not the problem. The problem is that it won't respawn at the empty game object I've got atop the paddle. Not sure what I'm doing wrong.

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

public class BallScript : MonoBehaviour
{
    //We need to interact with the rigidbody, to have it bouncing.  Thus, this variable.
    public Rigidbody2D rb;
    //This variable is to set up when the ball is and isn't in play.
    public bool inPlay;
    public Transform paddle;
    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        //Then we're adding some initial force...
        rb.AddForce(Vector2.up * 500);

    }

    // Update is called once per frame
    void Update()
    {
        //Checking the bool variable to see if the ball is in play.
        if (inPlay == false)
        {
            transform.position = paddle.position;
        }
   
    }

    //We're going to be setting up here, what happens when the ball goes out of bounds.
    private void OnTriggerEnter2D(Collider2D other)
    {
        if(other.CompareTag("Bottom"))
        {
            Debug.Log("Ball hit the bottom of the screen.");
        }
    }
}

[wintry quarry]

well you're making a direction vector toward the enemy and then you're applying an offset to the angle

so won't it always miss?

[midnight meteor]

where do i ask for help about installation ?

[wintry quarry]

well:

1. You're never setting inPlay to false
2. I don't see the point of the Update function at all, why not just reset the position directly in OnTriggerEnter2D?

[raw token]

#💻┃unity-talk, most likely

[rich adder]

#💻┃unity-talk

[midnight meteor]

thanks

[river quiver]

yeah

[wintry quarry]

Then you just do string displayStr = myFloat.ToString("F2");

[sleek marten]

Oh my god

bro 😔 my brain might be melted

[winter tinsel]

hey i just wanna know how making the controls of my game changable would work? not gonna implement it know just curious how that accesability feature would work

i have soemthing in mind but it uses alot of if statements...

[wanton kraken]

anyone know what the main issue is here? it's not setting itself to inactive, nor is it prompting the method. getting error "NullReferenceException: Object reference not set to an instance of an object", not sure why though

private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Player"))
        {
            Debug.Log("Got Collision!");
            BulletToAdd = RandomRoll();
            InventoryP1 playerInventory = collision.gameObject.GetComponent<InventoryP1>();
            playerInventory.AddBullet(BulletToAdd);
            gameObject.SetActive(false);

        }

[rich adder]

which line

[river quiver]

ty

[sleek marten]

is there an easy way to fix this or do I need to rewrite?

[wanton kraken]

my bad. this one. also hi navarone!

           playerInventory.AddBullet(BulletToAdd);

[wintry quarry]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.9/api/UnityEngine.InputSystem.InputActionRebindingExtensions.html

[rich adder]

seems playerInventory is null then

are you sure the collided object has a InventoryP1 script

[wanton kraken]

well. the InventoryP1 script is on BulletSpawn, which is a child of the actual Player that collides with it

[rich adder]

if its on a child of collider, use GetComponentInChildren

[wanton kraken]

i'll give that a try, thank you :)

[winter tinsel]

thanks

[wintry quarry]

I believe the input system comes with an an example rebinding ui too

[winter tinsel]

oh btw do you want to know how far i got with my game?

ive decided to develop it fully lol

cause its simple and i can use it to learn the rest of unity while still making a game, its not the game i want to make but it grew on me

[desert temple]

I'm not wanting to diverge from the tutorial I'm following for homework, lest I get lost later on. But the thing I need to do is having it set to false via...OnTriggerEnter2D, I think?

[wintry quarry]

Well if you're following a tutorial... just follow it!

[desert temple]

I am, and I'm doing something wrong, which was the initial reason I came here.

Since I can't figure out what.

[stuck palm]

for (int i = 0; i < colliders.Count; i++)
        {
            if (FixedCollisions.IntersectPolygons(colliders[i].GetPoints(), colliders[(i + 1) % 0].GetPoints()))
            {
                print("collision found!");
            }
            else
            {
                print("no collision");
            }
        }

why am i getting a dividebyzero exception on the if statement?

[wintry quarry]

because you're doing % 0 😱

that means "divide by zero and tell me the remainder"

[stuck palm]

oh

im stupid soz

meant to do colliders.count

[queen adder]

    public void DoRecoil()
    {
        targetRot += new Vector3(recoil_X, Random.Range(-recoil_Y, recoil_Y), Random.Range(-recoil_Z, recoil_Z)) * deltaMultiplier * Time.deltaTime;
        camRecoil.DoCameraRecoil();
        targetPos -= new Vector3(0, 0, zKickBack / 10) * deltaMultiplier * Time.deltaTime;
    }

Im trying to ensure that the recoil stays the same on all frames, however its still affected by the frames. That script is called each shot

Do i gotta use fixedDeltaTime...?

[wintry quarry]

unless you:

• Have perfectly linear motion that doesn't accelerate (change velocity) at any point
• Use FixedUpdate or a similar fixed timestep approach
  There will always be differences depending on framerate

Also it's unclear in your example - is this code running in Update or something

[queen adder]

No that function only gets called each shot, so often but not update

The Lerping is done in update and there doesnt seem to be issues with that

[queen adder]

So wait cant I use FixedDeltaTime then

[lethal elbow]

Currently have an issue where im trying to get my character (Just a capsule) to look towards the mouse cursor (3D space), I have a function that I found online but not having much luck. Was wondering if someone could help me out as the issue is the camera is now moving with the mouse instead of the player looking towards it. This happens when I assign the ground with a layermask

 private void GetMousePosition()
  {

      bool success;
      Vector3 Position;
      Ray ray = mainCamera.ScreenPointToRay(Input.mousePosition);

      if (Physics.Raycast(ray, out var hitinfo, Mathf.Infinity, groundMask))
      {

          success = true;
          Position = hitinfo.point;

      }
      else
      {

          success = false;
          Position = Vector3.zero;

      }

      if (success == true)
      {

          Vector3 direction = Position - transform.position;
          direction.y = 0;

          transform.forward = direction;

      }


  } 

[languid spire]

This is unnecessarily complicated. Forget the physics and use ScreenToWorldPoint on the mouse position

[mossy willow]

I have a problem

in my game

I want a camera to be the main one

and I have it tagged as main camera

and the other one is untagged

but when I start the game

it starts on cam2

[rich adder]

you can finish a thought before hitting send

Depth will tell you which one will be rendered above

[polar acorn]

All the tag does is determine which camera is returned by Camera.main. You'll need to manually deal with enabling or disabling them to control which ones are live.

Or you could just use cinemachine

[mossy willow]

ok thanks

[polar acorn]

https://unity.com/unity/features/editor/art-and-design/cinemachine

[lethal elbow]

Still a Ray or Vector3?

[languid spire]

Vector3. Your Position variable

[zenith crown]

Can i store inputs in a variable and if so should i switch the if and elif inputs to switches?

[languid spire]

you can store anything in a variable

[queen adder]

Do you mean Input.GetAxis()?

[zenith crown]

Nope i mean inputs of singular keys

[rich adder]

switches?

[zenith crown]

like sprinting

crouching

so on

[queen adder]

Thats a keycode, an enum, which can be selected with ints

So yes you can do something like

int sprintKey = 304

or

KeyCode sprintKey = KeyCode.LeftShift

[zenith crown]

Oh i was thinking more of something like this

I saw it in my course im taking

and thought i could use it

if i do it correctly

[rich adder]

a switch is simply a fancy if else chain

[queen adder]

Yeah

[zenith crown]

True

how bad is it to use a if else chain?

[queen adder]

the only reason I used it (Last time I remember) is for practice lol

[rich adder]

nothing bad about it all

without them you couldn't do much

[polar acorn]

It's just messy

[queen adder]

Switches look messier to me

[zenith crown]

Im fine with messy cause i organize my code with comments

[queen adder]

Wait till it gets bigger

[polar acorn]

The real solution is to try to engineer code to not need either switches or if-else chains

[rich adder]

ya if you have a giant monolith if else chain / switch , Your design is wrong

[zenith crown]

Im a indie dev and im trying the quicker way usually

[languid spire]

Switches are a damn sight more difficult to break when you change them than if else chains are

[queen adder]

Yeah but doing that will ruin it for you

[rich adder]

quicker != best necessarily

[queen adder]

Idk man cant say much, I used it like once in my life I think

[zenith crown]

Yeah i know but i feel like for what im doing it wont be bad

it will still be under 150 lines of code

[queen adder]

What are you even doing

[rich adder]

the lines of code dont really have relevance to how good the code is or performance

[zenith crown]

Currently changing speeds and getting it to work

Im gonna add the polish later

[rich adder]

this is horrid, you need a switch with a enum state

[dusty hull]

anyone know what to do?

[languid spire]

ok, so that is just wrong. Use Enums

[zenith crown]

Ok im gonna take a look at enums in that case

[polar acorn]

Set them all to false, then do one-liners for the individual buttons

[rich adder]

managing 6 bools for a state is madness

they wil certainly overlap at some point

[warm raptor]

do you know why my mesh deform when I raise my camera ? Is it coming from my script ?

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

public class CamRotation : MonoBehaviour
{
    [SerializeField] private float mouseSensitivity = 2.0f;
    private float rotationX = 0f;

    void Update()
    {
        float mouseY = -Input.GetAxis("Mouse Y") * mouseSensitivity;
        rotationX += mouseY;
        rotationX = Mathf.Clamp(rotationX, -90f, 90f);

        transform.localRotation = Quaternion.Euler(rotationX, 0f, 0f);
    }
}

[queen adder]

Non-Uniform scalling

[rich adder]

child of non-uniform parent

[queen adder]

whatever the gun is parented to doesnt have the same size on all axis

3, 3, 3 - Uniform
3, 1, 3 - Nonuniform

[rich adder]

never have root objects scaled other than 1,1,1 . Seperate your mesh from logic / holder objects

[queen adder]

I dont think it matters what number it is as long its all 3 is the same

[rich adder]

Having something to parent to have a larger scale will cause issues with other things, i keep my scaling strictly on the graphics itself

even physics dont play the same if you have large scales

[queen adder]

Yeah, well this is the usual gun setup for me

Thank GOD I can make parents inside of the gun models, for lerping reason, it would be so messy if it was all under the cam

[timber comet]

If(GameObject.TryToGetComponent(…)(out … var)) <——- how do I check if the collided object has an interface without saving it into a variable?

[zenith crown]

I just read this and realized i can simply store it as a int 1-5 which and write a comment for what every number represents

[rich adder]

TryGetComponent(out MYInterface _)

[timber comet]

Yeah, but I don’t want the out

[queen adder]

    private void OnCollisionEnter(Collision collision)
    {    
        if (collision.transform.TryGetComponent(out IInterface inter))
        {
            inter.CallFunction();
        }
    }

Theres nothing wrong with the out

[warm raptor]

how can I do, because the thing that doesn't have Uniform scale is my main caractère/colider , because I wanted the capsule to be higher but not larger (sry for my bad english)

[rich adder]

thats why i put _ discard symbol

[languid spire]

that is a [Flags] Enum, which does not seem to be necessary in your use case

[timber comet]

Ok ok, thanks

[rich adder]

thats literally what enums are... Ints with human readable labels...kinda

[zenith crown]

Im currently reading about enums give me a sec ill try to understand what you mean when im done

[safe radish]

is there a way i can check how many instances of a certain script are made?

[rich adder]

there is nothing complex about them

[queen adder]

have a camera holder, make that camera holder follow the player. Then you dont have to worry about size problems

[zenith crown]

Ohh they work like dictionarys in godot

you store an int for a string

[languid spire]

no

[rich adder]

there are no strings involved

[upper forge]

So im trying to make a puzzle game where you collect words in the world and once you collect them they go to the "TV' (the place where they will put the puzzle together, which is all in the same scene) once they are in the tv they cans be collected anymore and you are able to drag them around and put the words in specific points on the TV if it is the correct point it will stay if not it will return to the original place inside the TV

What would be the best way to go about this as there will be many different words

[zenith crown]

oh it looked like it from what i see

[zenith crown]

alright

does that work for tracking a pure class? or only if it has mono?

[rich adder]

dont put it in update or anything

this only finds Object from unity

FindObject would make no sense on a POCO

since POCOs are typically embedded inside another MB otherwise they are just files

[languid spire]

if you want to track these things a simple static int Count which you increment and decrement will do the job so much better

[safe radish]

static int will be shared by all instances of the pure class?

[languid spire]

exactly

[safe radish]

nice ill try that, ty

[languid spire]

increment in the constructor, decrement in the destructor

[raw orchid]

im having this issue with my movement whenever i click the left button to move left it moves right. please help

[safe radish]

that did the trick

[summer stump]

I get what you are saying here, but as they said, that is not accurate

For one, dictionaries in godot (and c# for that matter) hold a key value pair. The key COULD be an int or string, but it does not have to. (Same with the value). The key could be a gameObject reference and the value could be a list of vector3s if you wanted

On the flip side, an enum IS an int basically. Each value of the int just happens to have a name. It is not a string type though (which is an important difference for how it works)

[zenith crown]

Thank you for the explanation it cleared up my confusion

i get it now

Uhh why does this not work?

[dusty ember]

how do I detect if a player holds down a key

[summer stump]

It tells you exactly what to do instead
Movement is a reference. You do not use references for that

[dusty ember]

instead of tapping it

[summer stump]

GetKey, GetAxis, etc

As long as it is not down or up, it will be for holding

[dusty ember]

But i did this

        Input.GetKeyDown(KeyCode.W);
        {
            transform.Translate(Vector3.back * Time.deltaTime * carSpeed);
        }

and it just autodoes it

regardless

[summer stump]

No idea what "autodoes" means

[dusty ember]

If i dont touch it it still moves it

[summer stump]

Then there is some other code moving you, or your keyboard is faulty

Debug it with some logs

[dusty ember]

Okay

[summer stump]

Oh I see it

Your if statement is messed up

[polar acorn]

What about this code are you expecting to prevent your movement from happening every frame?

[summer stump]

That is not how you write an if statement in c#. Look closely at the end of the condition before the body

[polar acorn]

what if statement

[summer stump]

Oh yeah huh. I am blinded by everything wrong with this I guess

[summer stump]

I recommend a basic c# course
https://www.w3schools.com/cs/index.php

[dusty ember]

im doing the unity one

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

public class carMoveForward : MonoBehaviour
{
    public float carSpeed = 15f;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        Input.GetKey(KeyCode.W);
        {
            Debug.Log("ree");
        }
        
    }
}
``` I dont see anything wrong with it but it spams it

[summer stump]

Do the one I linked first

[polar acorn]

Tell me, what are you expecting to prevent the log from happening every frame

[dusty ember]

I need it to only do it If i press W

[summer stump]

There is A LOT wrong with this. A significant error that knowledge about the basics of c# would point you tk

[polar acorn]

So you should probably actually check if you press W

[languid spire]

because there is nothing conditional about this

Input.GetKey(KeyCode.W);
        {
            Debug.Log("ree");
        }

[dusty ember]

AH

I see

[summer stump]

Google "c# if statement" at least @dusty ember

[dusty ember]

I forgot the if

[summer stump]

Not only that

That is only one issue

[languid spire]

more than just that

[dusty ember]

i needed the )) Aswell

[summer stump]

Not only

[dusty ember]

And the first one (

it works

[summer stump]

Well yes, but still not everything

[dusty ember]

what

how

[summer stump]

Did you google "c# if statement" yet?

Look between the parentheses and the first curly brace

[dusty ember]

using System.Collections;
using System.Collections.Generic;
using System.Security.Cryptography;
using UnityEngine;

public class carMoveForward : MonoBehaviour
{
    public float carSpeed = 15f;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKey(KeyCode.W))
        {
           transform.Translate(Vector3.forward * Time.deltaTime * carSpeed);
        }
;
        
    }
}
``` But my code works perfectly

[summer stump]

Ah, you fixed it without mentioning it

The semicolon

[dusty ember]

yeah

[polar acorn]

Why's there just a random floating semicolon at the start of a line though

[summer stump]

You have another random semicolon in there for no reason though

[dusty ember]

this one?

ohh wait

nvm

[polar acorn]

Is that a semicolon?

[dusty ember]

I mixed it up

[zenith crown]

Why cant i open up project settings?

[dusk musk]

Hi everyone! Is this the right place to ask about GitHub? I recently picked up an older project, did some experimenting, and concluded what I did was crap. Now I want to restore my commit from 3 months ago, but I don't exactly remember how to do that. Can someone help? I want the circled one back.

[polar acorn]

Copy this value, checkout that commit

[languid spire]

rightclick, checkout commit

[dusk musk]

Thanks both! Here's a funny thing...

[languid spire]

you have uncommited changes

[dusk musk]

Ah I see. Thanks.

Where do I go from now? I have a detached HEAD.

Figured it out, thanks!!!

[bold plover]

If I were to pass states that are specific to a certain player state, would I pass that info to update or fixed update? I'm thinking fixed update because updating that information dependent on frame sucks yeah?

Though a tutorial I use that seems rather reputable but hasn't done state machines checks for player input in update.

Mostly want to know which is better practice.

[eager elm]

player inputs should be checked in Update

[ember tangle]

Does anyone have any resources about C# lambda functions? I'm looking for a cleaner way to check if one bool in a list of objects is true rather than a bunch of if statements.

[burnt vapor]

Sounds like something for Linq instead

Specifically the Any and Count method

[ember tangle]

ok i will look into that

[raw token]

I'm not entirely certain that I follow. But in broad terms, unless the data is pertinent to a specific frame or physics update, I'd generally move it around through events such that my functionality reacts as soon as it's updated... That is, any computed data is up-to-date as soon as the inputs change, and independent of frames or physics updates.

But yeah, for player input specifically - if you're not using Input System's event-based interfaces - I think you'd generally just handle player input in sync with wherever the Input Manager/Input System performs it's updates. Which is Update() for Input Manager, and also the default setting for Input System. Anything else might introduce some timing issues.

[queen adder]

lads, how much general C# should i learn before i get into the unity specific stuff?

[wanton kraken]

that didn't format well lol

[wanton kraken]

i'm shit at coding but started anyways with basic knowledge. i still suck but i learn more each day, and i enjoy learning via doing it rather then videos (though that's just me). i'd say do your best, and read documentation!

[forest mist]

and the if

xd

[queen adder]

alr alr fair

im grinding my way through a 4 hour course on the fundamentals like if statements and for loops etc and tbh im having quite a bit of fun learning it. I'll probably finish this course then learn the unity specific code after i finish the course 🙏

[eternal needle]

At the minimum id say you should understand classes and what instances are. But theres not really a proper answer without listing every single keyword or topic because people skip stuff that I assumed theyd do before classes.
General things, what data types are, methods/functions, classes and instances, loops, arrays/lists

[queen adder]

alrighty thanks lads

[forest mist]

just learn to program

it isn't learn "c#" in specific

[eternal needle]

The best way to learn also make sure you're not just reading/watching someone else code. You need to actually write it yourself, change values, see what happens when it changes. Try doing something the course didnt

[forest mist]

I would recommend learn the fundamentals for programming

then OOP and clean code

[wanton kraken]

wait no racoon please 🙏

i thought i had it figured but i dont

[raw token]

Sounds like you've declared Move() as a method which is called and operates on an instance of the PlayerRuler class, but where you're calling it in your code, PlayerRuler is not a variable containing a PlayerRuler instance, but rather the class itself.

Consider the class:

class FooBar {
  public void BazBaq() {}
}

Totally cool:

FooBar foo = new FooBar();
foo.BazBaq();

Error, attempting to call an instance method statically (directly on the type):

FooBar.BazBaq();

[wanton kraken]

thank you, this helps a lot

[spiral glen]

I needed i = 0

[eternal needle]

Do you realize how vague this could be for someone who's not done coding before? You've basically told them to learn to code which was their question on what to learn

[wanton kraken]

yeah

[spiral glen]

mb

[forest mist]

I told fundamentals

then OOP

then clean code

[eternal needle]

Exactly, which means nothing to a beginner

[queen adder]

yeah what im doin is im watching the guy explain the concepts and then mixing what ive learned together into one program

[forest mist]

what I have to say lol

[raw token]

In short, if the method is supposed to work sort of "globally," and independendently of any singular instance of the class, then you'd declare it as static and it would let you call it as PlayerRuler.Move().

But otherwise, you need to set up a variable containing a reference to the specific PlayerRuler you want to operate on, and call the method on that instead

[wanton kraken]

avoid those tutorials that tell you how to do each individual step on how to do something, you'll never learn. that's fine for specific stuff, but to learn broad concepts and how to use the engine check out the documentation and whatnot. those videos, like brackeys, aren't it

[forest mist]

learn variables, operators, if/else, for/while, functions...

[wanton kraken]

yep, gonna try that now

[forest mist]

that? @eternal needle

[eternal needle]

You dont have to say anything if u feel u cant provide anything more detailed or different than what I said above.

[queen adder]

yeah im learning the broad concepts, im not watching a step by step on making a whole program or whatever, im just learning how to use if statements and for loops

concepts that can be used in a whole load of different situations

[forest mist]

I told the basis to start in unity lol

fundamentals, oop and clean code

@queen adder https://www.freecodecamp.org/learn/foundational-c-sharp-with-microsoft/

[queen adder]

tyty

[eternal needle]

I used to tutor people for a decently long time. I fully understood what you wrote and yes it makes sense to learn those. But a beginner would google "OOP", read a bunch of buzzwords they dont understand and then immediately close the tab. Fundamentals also means nothing, how is someone who knows nothing supposed to know what's fundamental. Clean code honestly can be skipped too if we're just talking about knowing enough to just open unity

[forest mist]

well the point is

he has to google c# fundamentals first

I literally googled that

[queen adder]

i'd assume fundamentals means basic syntax and formatting of the specified language

anyways imma get back to this course

have a good one lads

[wanton kraken]

@raw token the error has disappeared in VSC, but still appears in unity when i try to use the method

public class Player1Movement : PlayerRuler
{
    public PlayerRuler PlayerRuler;

    // Start is called before the first frame update
    void Start()
    {
        PlayerRuler PlayerRuler = new PlayerRuler();
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKey(KeyCode.W) == true) {
            PlayerRuler.Move(Speed, KeyCode.W, PlayerRB, gameObject);
        }
        if (Input.GetKey(KeyCode.S) == true) {
            PlayerRuler.Move(Speed, KeyCode.S, PlayerRB, gameObject);
        }
    }
}

not sure if what's in start() is needed, but i tried it anyways to no avail

[raw token]

Oh alright, this class extends PlayerRuler - so any instance of Player1Movement is also an instance of PlayerRuler. Move() is member of the parent class, so it's accessible in the same manner as this class's own members (assuming it has an appropriate access modifier - public or protected).

public class Player1Movement : PlayerRuler
{
    // Update is called once per frame
    void Update()
    {
        if (Input.GetKey(KeyCode.W) == true) {
            Move(Speed, KeyCode.W, PlayerRB, gameObject);
        }
        if (Input.GetKey(KeyCode.S) == true) {
            Move(Speed, KeyCode.S, PlayerRB, gameObject);
        }
    }
}

[wanton kraken]

got it, thank you

much appreciated dude!!

[summer stump]

The second two are a rabbit hole that will hinder their learning. Especially the quite subjective topic of "clean code"

Amd they already said they are learning fundamentals

[forest mist]

the best he can do is not rushing

and understanding everything

[stuck palm]

if (colliderA is FixedCircleCollider circleA && colliderB is FixedPolygonCollider polygonB)
            {

will this check for classes that inherit FixedPolygonCollider?

[raw token]

Yeah 👍

[stuck palm]

i see

[raw token]

Though, if you need to access functionality specific to a child class, you'll still need to cast to that type

[cinder crag]

i need help with deleting my current held weapon whenever i buy/instantiate a new one , since rn i have a bow and a pistol in the shop , i go to buy the pistol , it doesnt replace the bow and its just there so both bow and pistol are instantiated and im not sure how to delete the last equipped weapon like delete the bow when buying the pistol for example

[rustic valve]

Hi, I'm having some problems with the DontDestroyOnLoad objects, i'm trying to get the component "Unit" that is in: party -> Teammate1 -> Unit, but when I assign it, it doesn't refer to the actual object, I think it is creating a new "unit" component to reference
https://pastebin.com/svcBNAK8
i think the problem is in line 20-24, but I can't find a way to fix it

[raw token]

You need a reference to your current weapon, then you can Destroy() it's game object (or disable it)

[cinder crag]

and how can i reference my current weapon?

[polar acorn]

Well, how do you identify your current weapon? What makes something your current weapon?

[cinder crag]

i dont have something to identify my current weapon

[polar acorn]

So then what even is a current weapon

[raw token]

Is this script on the DDOL game object?

[cinder crag]

the player starts with the bow so that the player current weapon and when you go buy the pistol , you delete the bow then the player will have the pistol as its current weapon

[polar acorn]

So then store a reference to the bow, and destroy that when you get a new one

[cinder crag]

yeah but how can i make it so it works with the future weapons so if you buy an AR , the pistol must get destroyed then the AR will be the current weapon , do i have to store another reference other than the bow or how can i do it?

[polar acorn]

Store the new weapon in the current weapon variable when you get one

[cinder crag]

okay got a way to get the currentequippedweapon but now im not sure how to destroy the current equipped weapon since well it cant be destroyed cuz of data loss

[strong wren]

Destroy the instantiated object instead of the prefab asset. Store the instantiated weapon in a separate field.

[cinder crag]

how can i store the instantiated weapon in a separate field?

[polar acorn]

Instantiate returns a reference to the object it creates

[cinder crag]

im sorry but my brain just stopped , wdym by that?

[raw token]

Within EquipWeapon(), what does the variable weaponInstance contain?

[cinder crag]

well the Instantiated weapon prefab

instantiating n such

[raw token]

Sounds an awful lot like the thing you eventually want to Destroy, no?

[cinder crag]

i tried doing this but it just destroys the weapon so im not sure on what to do

[raw token]

So it's achieving the right effect, but at the wrong time. You don't want to destroy the weapon which was just equipped - you want to destroy the weapon which was equipped prior to the new weapon, if any

[cinder crag]

basically i want to destroy the current equipped weapon , i have a bow and when i buy the pistol i want the bow to be destroyed

[raw token]

#💻┃code-beginner message

You currently have a reference to the weapon which was just instantiated within the current call to EquipWeapon(), but you need a reference to weapon instance which was instantiated in the previous call to EquipWeapon(). So you need to persist a value between calls to EquipWeapon(). Local variables within a method die when the method ends, but class fields don't...

If this still doesn't quite add up, it might help to write out a bullet point list of what should happen when a weapon is equipped

[cinder crag]

so create a class inside the EquipWeapon() methoh then destroy the weaponInstance in there , i think thats what u mean

[raw token]

No new classes or class instances are required

The sequence of events is as such:

• Player picks up a new weapon
• If the player currently has a weapon, Destroy it
• Create the new weapon
• The current weapon is now the newly created weapon

[cinder crag]

how can i check if the player already has a weapon?

[raw token]

The current weapon variable will be null. Though if your player is never without a weapon you don't necessarily need to worry about that case

[polar acorn]

Why is currentlyEquippedWeapon an int and not a WeaponShooting

[cinder crag]

cause i have a weaponType in my WeaponsSO script and i just set the currentlyEquippedWeapon to the index of that array so the bow is 0 and pistol is 1

[polar acorn]

So how do you go from an int to a WeaponShooting

[cinder crag]

just cast the weaponType as an int

[polar acorn]

So, how do you go from an int to a WeaponShooting

[cinder crag]

im not sure what you mean

[polar acorn]

The WeaponShooting object you want to destroy

How do you plan on getting it from an int

[cinder crag]

well as i said the Bow is 0 in the array and Pistol is 1 so thats how i get it from an int

[polar acorn]

Okay and how does that get you a reference to a WeaponShooting you want to destroy

Since you've decided to use an int instead of referencing the object, what is your plan to get to the object from that int

[cinder crag]

i have the weaponShooting as an array

[polar acorn]

Okay, are those prefabs or are they objects in the scene?

[cinder crag]

they are prefabs

[polar acorn]

So then the question remains: How do you intend to use this int to get a reference to the WeaponShooting that you want to destroy

Maybe it shouldn't be an int at all

maybe the variable for holding your current weapon should hold the current weapon

[raw token]

Prefabs are templates - they describe the shape or concept of something. Your currentlyEquippedWeapon variable holding a reference to the prefab (or some value on it) is sort of like saying "my current weapon is the idea of an AK47" rather than "my current weapon is this specific AK47 which is in my hands"

[cinder crag]

now i realized it was stupid to use an int so i jsut changed it to a WeaponShooting but when i want it to be desstroyed it says it cant be destroyed to avoid data loss

[eternal needle]

look at the error closely, it should say more than just that (its a prefab)

dont paraphrase or skim through when it comes to errors, the full thing should be "Destroying assets is not permitted to avoid data loss". It being an asset matters because this means you're trying to destroy something in your folders and not an object in the scene

[cinder crag]

mb mb , didnt mean to

but how do i destroyed the current weapon equipped that is in the scene?

[summer stump]

What you call currentlyEquippedWeapon is actually NOT the currently equipped weapon, it is the prefab you instantiate the in scene object from

That object you instantiate is the currently equipped weapon

[round plover]

anyone know why theres error

[summer stump]

See the character right after 500?

[raw token]

Yes, but read the error 🙃
