#

Making a += overload without returning anything is technically not standard C(++)

#

This can cause issues depending on who will use your library

burnt vapor
#

+= is fine, it's the multiple inline assignments that makes my skin crawl

#

Never had a use for it anyway

languid spire
#

ok, so how would you set 3 variables to the same value?

devout flume
#

Yeah, it applies to all of them either way

devout flume
languid spire
#

I have no problem with a = b = c = 1; Makes perfect sense to me

burnt vapor
#

To avoid an unneeded discussion, let me just say that the average person would have to spend a significant amount of time figuring out what a line like that would do. That would be enough reason to advice against it tbh

devout flume
burnt vapor
#

And it might have been a mandatory thing in C or C++, but this is a C# server

languid spire
devout flume
#

I'm the kind of person to do

int fd
if ((fd = open(...)) != -1) {}
devout flume

#

Sorry, maybe I'm a bit quick to judge, but it has only been a few days since somebody here suggested the use of a nullable boolean because it's good to have a "maybe" state 😎

devout flume
#

That's standard C yes

burnt vapor
#

If you have to go out of your way to figure out why something like it exists (in this case it would be relevant for both) then it's time to rewrite

devout flume

burnt vapor
#

You think the average programmer would care?

languid spire
#

no, but they should

burnt vapor
#

Of course not

#

If you would care so much about this then you would not write with C# to begin with

languid spire
#

wrong, you use the tools which are available to you in the context of which you are working

burnt vapor
#

Let's at least learn the beginners the proper way to manage states then 😛

languid spire
#

how about we just educate them to think, that would be a damn good start

im instantiating in a card in script and then in its awake function im creasing the alpha from 0 to 255 howver once the alpha gets to full the cubes start to blend together (the cards are two small cuboids stuck to the back of eacother

Is there a cell count limit for unity's built-in "Grid" component? Like 10 rows and 15 columns or something like this?

#

If I had to guess, probably 2,147,483,647

of course actually havoing data in that many cells will be a memory limitation on your system overall

I can't seem to find a way to get all the scenes in my project that aren't loaded, and from there get their names.
From what I understand, I only have the option of fully loading a scene with a specific index to check what the name of it is.
If this scene doesn't exist, then it just doesn't load.
SceneManager.sceneCountInBuildSettings gets the amount of scenes in the build, which is 3 for me.
I then attempt:

for (int i = 0; i < SceneManager.sceneCountInBuildSettings; i++)
        {
            //(doesn't work) Scene s = SceneManager.GetSceneAt(i); 
            //(doesn't work) Scene s = SceneManager.GetSceneByName(name);
            Scene s = SceneManager.GetSceneByBuildIndex(i); //doesn't work

            if (!s.IsValid()) continue;

            if (s.name.Equals(name, StringComparison.OrdinalIgnoreCase))
            {
                return s;
            }
        }

This, however, tells me that I don't have a scene at index 1 because it isn't loaded.
I need some way of "peeking" at a scene, like in a list without having to pop the damn thing.

#

it finds the first scene in the index, because that's the currently loaded scene. The rest are invalid with an index of -1. It's not a valid scene, even though I know there are scenes at index 2 and 3.

wintry quarry
#

The rest of those functions (SceneManager.GetSceneXXX) only work with scenes that are currently loaded.

#

This is the kind of thing that a lot of games end up building some custom tooling around, i.e. with ScriptableObjects and some pre-build scanning editor script.

How can i assign controller 1 too player 1 and controller 2 too player 2? Because righnt now both controllers controll the same player

#

Not that I'm aware of

#

It feels like a limitation because it is one

#

Unity doesn't have a way to read "metadata" from a scene before loading the scene

@wintry quarry so, what do I do then? I need to load all scenes in the background and store their names based on index...?

is there a more efficient/common way to see if two Vectors are nearly equal, or is this fine?

    private bool PositionsAreEqual(Vector3 pos1, Vector3 pos2, float tolerance = 0.1f)
    {
        return Vector3.Distance(pos1, pos2) <= tolerance;

well, that was an adventure! With my extended programmer (i hate to say it, but it is ChatGPT 4o and 4o-mini). i now have two scripts that together do the following:
Place a Nav Mesh Obstacle where any Terrain Tree is, since there is a bug in the system that does not add a tree as an Obstacle in the Nav Mesh Surface. https://issuetracker.unity3d.com/issues/navmeshsurface-trees-placed-on-terrain-are-not-taken-into-account-when-baking-navmesh (thanks @steep rose finding that, and stopping me from wasting more time). this allowed NPC/AI/Player to walk through trees, or to get Nav glitched on them if you use Tree Colliders, which i consider absurd. Automatically swap to a Prefab version of the Tree when close, and back to Terrain Tree when you walk away. i use the same Prefab to make the Terrain Brush since it strips everything except basically the Mesh/Mesh Renderer anyways. this allow an auto swap to the correct prefab without having to manually cross reference which Prefab should replace which trees. The common rotation and scale issues are resolved and match perfectly when swapped back and forth between Prefab and Terrain Tree (Thanks @robust schooner for a vital piece of information about that).
The Nav Mesh Obstacle is Destroyed and the Nav Mesh hole/Carve is removed automatically when the Tree is chopped down/Destroyed/is temporarily in Prefab form. i may change it a bit to keep the Obstacle in Prefab form, and remove only if either Terrain Tree, or Prefab is Destroyed.

the first thing id start with is detecting when objects are on the moving platform, then applying the same movement that the platform does to those objects. many tutorials will show you just parenting the object under the platform, which is really not ideal in a ton of cases

Visual Studio works best but just for Windows (or Mac, but I believe it's discontinued)

#

Rider also works best, is cross platform, but requires payment

#

There's the EAP for Rider which means you could get it for free, assuming you read the license

#

VSCode also work but it has always had bas support. However, I believe it is better nowadays so it might also be a good option now (haven't checked)

#

Also next time, use the proper channel pls

All u need is the inventory system and load system I think

#

Basically I load my SampleScene from my Main scene and I save the game in the SampleScene. When I try to load my samplescene from my mainscene with my loaded data everything is setup nicely except for my inventory 😦 It just doesnt save

burnt vapor
#

What you should do is retrace the steps up until the saving, and see where it goes wrong

#

See if the data is passed into the part that saves, see if the savng happends, then see if the data is saved

#

When that's done, do the same but in reverse for the loading

#

Retrace your steps until you find out where it breaks

wooden lance
#

Ye I know my guy, I've been doing that for a couple of days. The debug log shows that the item is saved, in the right index, etc. So I am kind of at a loss

burnt vapor
burnt vapor
#

Set a breakpoint, follow the steps the code does

#

See if data comes in, see if it's valid, see if it gets passed down to the relevant dependencies that need it

#

The debugger allows you to view the contents of variables

#

With all due respect, the time it takes to do this will be shorter than what it takes for anybody here to read the hundreds of lines you shared

#

Once you know what specifically goes wrong, you can share that part of the code in here in case you don't know the reason

I want to create a system for attack with a bow and change the value of the power of the bow compared to the time the player stay click on the mouse. But, with I have done, my game crashed so I think I have an infinite loop.
The code :

        isRightClickHeld = context.ReadValueAsButton();
        Debug.Log("Click hit weapon");

        if (isRightClickHeld)
        {
            ArrowTimer();

            isCooldown = true;
            StartCoroutine(AttackDelay());
        }
        
    }

    private IEnumerator AttackDelay()
    {
        yield return new WaitForSeconds(currentWeapon.attackDelay);
        isCooldown = false;
    }


    #region Arrow System

    public void ArrowTimer()
    {
        while(isRightClickHeld)
        {
            timeRightClickHeld += Time.deltaTime;
        }
        ThrowArrow();
        timeRightClickHeld = 0;
    }

It doesn't end

#

You need to ensure it checks each frame

#

Add yield return null; inside the while loop

languid spire
night valve
#

Right why don't you use coroutine like you did in cooldown

burnt vapor
#

C# / Unity uses threads and you are hogging the main thread with a while loop that runs infinitely on a single frame

#

So either you add that yield line and check once per frame, or you run it in a background thread (which is a bad solution here!)

#

Actually, this is wrong

#

Your method is not even a Coroutine

atomic holly
atomic holly
burnt vapor
#

There's a lot wrong with this code

#

Make the method a Coroutine, add the yield

#

Then you want to call StartCoroutine for the method in ClickHitWeapon

languid spire
#

or read the button INSIDE the while loop

burnt vapor
#

Lastly, assuming you want to trigger the cooldown after, add isCooldown = true; and StartCoroutine(AttackDelay()); at the end of the method, or have another coroutine call ArrowTimer and wait until it is finished, and then call those

#

Regardless, your current code is not going to do what you want at all

You don't have to always yield WaitForSeconds, you can return null until button gets released

Imho dots are good start instead of monobehaviors, BUT you NEED to know a C# better

night valve

If you prefer to learn unity along with c#, start with normal OOP

wheat coral
#

Ok

rich adder
#

I mean you can use it, I just wouldn't recommend it until you learn more coding

#

there is a lot of different concepts that are not regular to oop

night valve
rich adder
#

yes its very good for performance, but writing the code is very boilerplate in the beginning and annoying. Not the best for beginner

night valve
#

Was thinking more about not getting narrowed mindset by mono:p

#

I struggle with this a bit now

rich adder
#

imo, at the end of the day you're making a game so yes performance is important but if it hampers progress then its not worth the time unless you really having performance issues that traditional means do not solve

night valve
#

That's right. But if it is only about learning unity, eventually you end up using mb anyways, but can start learning in different order

rich adder
#

true, i just see it as you gotta learn the "wrong way" first to see the major benefits in the "correct way"

dark laurel
#

I wouldn't even worry about DOTS until you know why you need it imho

#

I have games with "thousands" of instances of items for mobile and they work just fine.. migrating or doing it in DOTS wouldn't improve performance since we're already fine at 60fps and would greatly increase complexity

#

"greatly" if you're a Unity beginner, that is

wintry quarry
#

To play devil's advocate - even after reaching your framerate targets, improving performance still:

  • Reduces energy usage (reduced battery drain) of your application (which user's might not notice at first but will eventually)
  • makes it accessible to even more devices
#

but noit worth entertaining those goals without concrete targets either

rich adder
#

Btw I was mainly referring to ECS when speaking dots, cause dots and mb work together just fine so its not like we choose one or the other luckily unity can use both and we can mix GOs with ECS or just use things like JOBS which are very useful MB or not

night valve
#

Agreed, can't think of advantages of doing "pure dots" for a game. But making a system to handle specific area of that game just to offload CPU, even if not necessary, isn't bad idea imo

I had to make an init scene and put my singletons for data persistence and scene management in it so the data in them would be ready for fetching beforehand. When I start the game from init scene, I load the playable scene additively and set it active. I log the active scene and yes it successfully makes the newly loaded scene active. My problem is that I cannot interact with anything when I'm loading from init scene. And the lighting settings are all messed up. Why is that?

rich adder
final kestrel
#

Yes they are DDOL.

#

This is the init scene objects

image.png
rich adder
#

and also which do you mean when saying

cannot interact with anything

#

what are you trying to interact with ? what's supposed to happen

final kestrel
#

I set up interactables in my playable scene that I can interact with. When I start playing from my playable scene it all works fine. I can interact with the objects and such.

#

Like a fridge. I can open and close its door.

rich adder
#

did you check the console for errors?

final kestrel
#

These are the only errors I'm having

image.png
rich adder
#

hmm seems like some objects are not being carried over in DDOL unless their parent is already ddol

final kestrel
#

I also check the layers of my interactables to see if they change or anything but no everything looks fine

rich adder
#

unless you specifically coded to do so

final kestrel
#

Nope i did not code anything of sorts.

#

Maybe changing scene messes something up

#

thats why I checked

rich adder
#

clear

#

but the "why" is why you debug lol

rich adder
final kestrel
#

The ones that carry over to my playable scene. They are not child to any other object

image.png
rich adder
#

ok and no camera?

final kestrel
#

Camera does not carry over. I have my camera set up in the playable scene

#

I mean i did not anything about it. Does it usually get carried over?

rich adder
#

nah just wondering if you had that on DDOL

#

see if the interactions script is running and put debugs see whats happening inside when new scene switched

final kestrel
#

Like when I delete the camera from the init scene. My playable scene camera changes angles and stuff

rich adder
#

I'm not sure how one would affect the other

final kestrel
#

I do not know either

rich adder
#

are you saving values n stuff?

final kestrel
#

Just simple booleans about the game checkpoint.

rich adder
final kestrel
#

Wait why the hell is my camera coming with me

#

There is one camera in init scene.

#

And there is another in my playable scene?

rich adder
#

ah well there you go, you might be raycasting from the wrong camera..

rich adder
final kestrel
#

Yeah when I disable the first camera. The interactions and all works now. The question is

rich adder
#

I did ask about if it was being brought with DDOL. Check all the ddols you're making

final kestrel
#

I start my game by playing a timeline in the playable scene. Why does disabling init scene camera changes the angle?

final kestrel
#

Like I only have 2 3 ddols in scene and there is nothing related with camera being carried over

rich adder
final kestrel
#

These three come with me from init scene

rich adder
#

are those the only DontDestroyOnLoad you have in script?

rich adder
#

you just made new one active, possibly

final kestrel
#

Well I cannot unload the init scene. I have to have the game data ready all times. Its like, I start a new scene, new scene checks the data if necessary and loads the game accordingly

#

If i try loading the data and make my scene act on it, the data does not get loaded immediately leaving with exceptions.

rich adder
#

what is even the point of DDOL then..

final kestrel
#

I mean it may be wrong but thats what I could come up with.

#

So you're saying they are already in the init scene why carry them over with you. They will already be available

rich adder
#

if you dont unload the scene objects don't even get unloaded there is no point in DDOL

final kestrel
#

Yeah never thought about it damn

rich adder
#

DDOL is a scene that just never unloads (between scene changes)

final kestrel
#

So like they will be loaded at start in init scene and stay there for me to read and write. Makes sense

rich adder
#

once they are in DDOL(code) they should be put automatically in DDOL(scene)

#

so its kind of seamless

final kestrel
#

Hm okay. So what should I search for about the lighting issue?

rich adder
final kestrel
#

All right. I am also new to the lighting things. I must research. Thanks a lot for your help. You're the best.

#

I've a problem, why at the start of the game I can adjust the volume but when I start the game and return to the main menu I can't adjust it anymore?

#

(if the code is needed please tell me)

rich adder
#

well yeah, we can only guess without seeing code/setup

#

presumably some null reference

stone pilot
#

Alright, so the adjusting volume is just a scroll bar, and when you return to the main menu this is the code

{
    if(Input.GetKeyDown(KeyCode.Escape))
    {
        PlayerPrefs.SetInt("LoadSaved", 1);
        PlayerPrefs.SetInt("SavedScene", SceneManager.GetActiveScene().buildIndex);
        SceneManager.LoadScene(0);
    }
}```
languid spire
#

and what does any of that code have to do with the volume?

rich adder
stone pilot
rich adder
#

we need to see the code that gets Input from the slider and outputs to the audio volume

#

guessing some reference in scene switch breaks

stone pilot
#

Well there's no code ig.. I added the music prefab and set the volume in the slider

image.png
#

Is there a better way to do it or smh else?

rich adder
#

ideally a persistend audio ddol object + audio manager

rich adder
#

unless it cant find Music anymore somehow

#

if you mean its not saving the same value then see above

stone pilot
#

That's the problem, I think the problem is with the switching scene code

stone pilot
#

If I try adding volume saving will that works?

#

I found a script on reddit I'll try making that

rich adder
stone pilot
#

You can see the video I've sent up

rich adder
#

did you check if you have any errors in console when you switch scene back?

stone pilot
#

Not really, there's no errors at all

rich adder
#

can you show the Music object inspector, when you switch back to that scene

stone pilot
#

Alright, I'll record a video

Unity does not support NuGet, because it has the control over your C# project file. When you include a NuGet package, VS writes it to the project file, Unity detects the changes and rebuilds the project file entirely before recompiling. You lose the changes VS made

unity 6 is the most stable and performant version of unity and you can set unity flash screen as optional

torpid jetty
#

Thanks for clarifying, I was a bit confused XD

#

I haven't been able to verify this for myself, but my understanding is that U6 should improve overall performance in some respects, especially with the lighting system?

#

At least that's the impression I've been given, mostly based on just a few YouTube videos that have talked about it.

I didn't have many issues during the preview period, so it's what I'm using for my own stuff at the moment. (again, small projects, so that probably doesn't say much)

I have high hopes for whenever they get around to updating the engine from mono to .net core, though... but it'll be a while, unfortunately.

even in unity 6 you have legacy, you can also choose to install the new one in 2022

when working with events, is it common practice to unsubscribe from the event i subscribed to once its no longer used?
lets say i have a falling object called disc, which upon finishing its fall it fires an event "stoppedfalling". everytime i create the disc i should subscribe to the event, and then wait for the event to fire, where i start it by unsubscribing the object from the event since i assume itll never be falling again once its in place

#

specfically unsubscribing from within the same event

cosmic dagger
snow apex
# 

    private void SpawnedDisc_StoppedFalling()
    {

        // Detach Event
        spawnedDisc.StoppedFalling -= SpawnedDisc_StoppedFalling;

        // Code
        //
        //
    }
#

im a complete beginner, whats on enable and on disable?

#

is it scopes like start and update?

cosmic dagger
#

they are Unity methods. you place the subscribe code inside one method, and the ubsubscribe code in the other method . . .

snow apex
#

of the object definition

cosmic dagger
#

OnEnable is automatically called when the GameObject is enabled. the same applies to OnDisable (but obviously the opposite) . . .

snow apex
#

gotcha, its sorta like the enter and exit dunders of python classes

i have 2 objects i cant access..
an igrid and a idisk

the igrid is spawning the idisk. after its spawned i keep it in a variable and immediately subscribe it. but then when i spawn the next one for some reason the event that is subscribed is fired twice for the one i just subscribed to, and once for the old one i subscribed before. i found the solution by unsubscribing from the inside of the subscribed method after its fired, but i was wondering if it was a good practice

Hello everyone :-),
Im wondering why my player isn't properly rotating towards the mousePosition.
when i attach this script to the player object it creates a weird rotation effect. Its responding to the mouse Movement but it doesnt properly rotate towards the mouse Position. Please Help.

using UnityEngine;

public class PlayerRotation : MonoBehaviour
{
    [SerializeField] private float rotationSpeed = 5f;
    [SerializeField] private LayerMask groundLayer;
    private Camera mainCamera;

    private void Awake() {
        mainCamera = Camera.main;
    }

    private void Update() {
        RotatePlayer();
    }

    private void RotatePlayer() {
        if(TryGetMousePosition(out Vector3 mousePos)) {
            var dir = mousePos - transform.position;
            dir.y = 0;
            transform.forward = dir;
        }
    }

    private bool TryGetMousePosition(out Vector3 position) {
        var ray = mainCamera.ScreenPointToRay(Input.mousePosition);

        bool success = Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity, groundLayer);
        position = hit.point;
        return success;
    }
}

If that doesn't solve it, you may want to add on the player position + direction to localize the direction. I forget

cosmic dagger
# echo sand this happens when its grounded

your code only logs the value of CC.isGrounded. we can't determine anything from this. you need to check/show us the code that determines how the player is grounded . . .

echo sand
#

it has its own "isGrounded" variable

silver cobalt
#

and thank you agaain for the help

finite dove
#

and specially how you tell / invoke it to another code

snow apex
finite dove
cosmic dagger
# echo sand its Charactercontroller

it can be a collider issue. make sure it's properly setup. are you on a slope? if so, slopeLimit could be the problem as well. is your character just on a flat surface?

#

#

and also how the beaviour of the mouse influences the rotation of the pllayer with the current code setup?

timber tide
#

I'd make sure the position is correct from the raycast, and print out the transform position and direction and make sure those values are correct

#

sometimes when I'm not sure if the values are lining up I'll stick what I'm working on at the origin such that I know that (0, 0, 1) is forward in both the local and world direction

i figured it out. the problem lied in the fact that i was using a render texture on my cam to achieve a pixelated effect but the mousePos wasnt accounting for that

i mean subscription just like Radio, you send the radio then if someone like it it will continue hear the radio talking until it finish.

cosmic dagger
# snow apex what do you mean?

no, i read the code wrong. it's hard to see when all broken up.

  • the instance created is spawnedDisc
  • then you access the StoppedFalling event from spawnedDisc
  • SpawnedDisc_StoppedFalling from this script is subscribed to the StoppedFalling on spawnedDisc
    i thought SpawnedDisc_StoppedFalling was a method from the spawnedDisc instance . . .
snow apex
#

ah no, its another event of the disc that has been spawned inside the subscribed method of ColumnClicked

#

so basically i gather the information i need for spawning a disc, reach a scenario that requires a spawned disc, then i spawn disc based on an event that is subscribed to the game board which broadcasts the fact and location of what column is clicked.
that results in a spawned object that will communicate when it arrived at its slot

second, firing up unity

this is the code

#

and the thing is instead of maintaining a pace and spinning around infinitley it slows down and stops at abt 90 degrees

#

now i dont really understand quanternions so and explanation would be great

rich adder
#

yes because Slerp is going from a start rotation to a target rotation

#

if you want to rotation just do
transform.Rotate(0,0, horizontalInput * rotateSpeed * Time.deltaTime)

#

also configure your IDE

queen adder
rich adder
#

btw Quaternions are just representation of rotation in 3D space

queen adder
#

yeah just out of curiosity since i didnt set it

rich adder
#

just know you need to work with Euler angles -180 to 180

#

using quaternion for rotations prevent issues with gimbal lock

Two of the rotation axes become parallel to each other, meaning a rotation around one axis effectively affects the other, causing a loss of independent control over one degree of freedom.

# hasty dragon how do you put a scene as a variable

for runtime stuff you don't. you can use a string or an int. there are third party assets like NaughtyAttributes and OdinInspector which add stuff that allow you to pick a scene from a dropdown though, but it's still either a string or int

thorny basalt
#

This is a good place to start

#

Some teams use different conventions but that is what I personally follow

seems everyone uses camel case and suggests it. I use snake case because I haven't really seen anything in the language that uses underscores so they kind of stand out

...although sometimes it's inconsistent 💀

Odd question, I'm quite new and am sure this is probaly really easy.

I need to swap a corpse's model to a Loot Bag on death (so this involves swapping the Mesh).

Hey guys, what's up...?

#

I'm kind of new to Blendspaces in Unity, and Unity in general to be honest

#

The animations were working before but I changed up my code a bit and it stopped working somehow

#

Someone said that my code is stuck in the "Vertical Velocity" Blendspace (it has Jump, Double Jump and Fall in it)...I'm not sure why

#

This is my snippet of code for my animation logic

        //Animation Logic - Horizontal Movement
        if(horizontalMovement == 0) {
            sidAnimations.SetFloat("Horizontal Velocity", 0.0f); //Idle Logic
            } if(horizontalMovement != 0) {
                sidAnimations.SetFloat("Horizontal Velocity", 1.0f); //Walking Logic
                if(runningAction) {
                    sidAnimations.SetFloat("Horizontal Velocity", 2.0f); //Running Logic
                }
            }

        //Animation Logic - Vertical Movement
        if(verticalMovement > 0) {
            sidAnimations.SetFloat("Vertical Velocity", 0.0f); //Single Jump Logic
            if(jumpsLeft == 0) {
                sidAnimations.SetFloat("Vertical Velocity", 1.0f); //Double Jump Logic
            } else if(verticalMovement < 0) {
                sidAnimations.SetFloat("Vertical Velocity", -1.0f); //Falling Logic
                }
            }```
#

This is the value of horizontalMovement, basically just the X-values (after watching the tutorials on the new Input System)

image.png
#

I set the parameters Horizontal Velocity and Vertical Velocity (one for each blendspace), based on my player's axis movement

#

I'm not sure why the animation is basically locked in my Jumping blendspace...

Is there a way, how I can check those Inputs without creating 6 if statements?

If you know Minecraft, there is a Hotbar down for the inventory with 9 Slots you can target with your mouse wheel. But you also can just press the Number Keys to get directly to the Inventory Slot.

My inventory is similar to this, but instead of 9 Slots, I only need 6.

        bool _DirectSlotButton1Pressed = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();
        bool _DirectSlotButton2Pressed = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();
        bool _DirectSlotButton3Pressed = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();
        bool _DirectSlotButton4Pressed = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();
        bool _DirectSlotButton5Pressed = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();
        bool _DirectSlotButton6Pressed = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();

        if (_DirectSlotButton1Pressed)
        {
            _AktullerHotbarSlot = 5f;
            _Slider_Hotbar.value = _AktullerHotbarSlot;
        }
        if (_DirectSlotButton2Pressed)
        {
            _AktullerHotbarSlot = 4f;
            _Slider_Hotbar.value = _AktullerHotbarSlot;
        }
        if (_DirectSlotButton3Pressed)
        {
            _AktullerHotbarSlot = 3f;
            _Slider_Hotbar.value = _AktullerHotbarSlot;
        }
        if (_DirectSlotButton4Pressed)
        {
            _AktullerHotbarSlot = 2f;
            _Slider_Hotbar.value = _AktullerHotbarSlot;
        }
        if (_DirectSlotButton5Pressed)
        {
            _AktullerHotbarSlot = 1f;
            _Slider_Hotbar.value = _AktullerHotbarSlot;
        }
        if (_DirectSlotButton6Pressed)
        {
            _AktullerHotbarSlot = 0f;
            _Slider_Hotbar.value = _AktullerHotbarSlot;

Is there also a solution for the Input action Map to keep this also clean?
Instead of using 6 extra actions just for an alternative keybind for the Hotbar?

ivory bobcat
#

I'm not too aware of the new input system but you should be able to poll input as well if you're not liking the other two methods of acquiring input (event subscription and something other that I do not remember)

cosmic dagger
#

C# events (code), unity events (inspector), polling in Update (code) . . .

ivory bobcat
#

Not sure if manually loading would be considered creating... UnityChanThink

#

I'm assuming they would have to create the actions in Unity, export as json and reimport. Unless.. they simply write it in json...

zenith cypress
#

If you already have premade bindings I'd just put them in an array like Dalphat suggested with something like:

// rough example since it is very late for me lol
struct Foo {
  public InputActionReference action; // w/e the type is
  public int slotIndex;
  // constructor
}

private Foo[] _slotActions = new Foo[6];

void Init() {
  var playerMap = _controls.Player;
  _slotActions[0] = new Foo(playerMap.Inventory_Hotbar_DirectSlot1Button, 5);
  // etc
}

void Run() {
  foreach (var slot in _slotActions) {
    if (slot.action.WasPressedThisFrame()) {
      _AktullerHotbarSlot = slot.slotIndex;
      // do thing
      break;
    }
  }
}

Could simplify the premade actions into generated ones, but not sure how those work with things like the PlayerInput handler, would also have to manually enable/disable/dispose them

// actual binding name is probably wrong here
// can generate them in a loop
_slotActions[0] = new Foo(new InputAction("slot_0", binding: "<Keyboard>/1"), 5);
// etc

Food for thought anyhow 😄

# ivory bobcat Direct answer: An array and loop

The part with the array and loop...
Are you sure this will it not overcomplicate the script and make it even harder to read than 6 if statements, in case you will visit the script again in 4 years later or something?...

#

But I also run in an issue here with:

_DirectSlotButton1Pressed = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();

Because I cant make an array in the new input system action map and how can I replace the "1" with a 2,3,4,5,6 in this loop of the "Inventory_Hotbar_DirectSlot1Button", if I can't make an array in the New Input System Action map?

        bool[] _DirectSlotButtonPressed_ARRAY;
        for (int i = 0; i < 6; i++)
        {
            _DirectSlotButtonPressed_ARRAY = _controls.Player.Inventory_Hotbar_DirectSlot1Button.WasPressedThisFrame();
        }```
scenic maple
#

You add the array of buttons as a field in your class and iterate over that

# 
for (int i = 0; i < _buttons.Length; i++)
{
  if (_buttons[i].WasPressedThisFrame())
  {
    _sliderHotbar.Value = _buttons.Length - i;
  }
}
spring skiff
#

are we still talking about Keyboard Buttons or UI Buttons?

scenic maple
#

Whatever "Inventory_Hotbar_DirectSlot1Button" is

spring skiff
scenic maple
#

Just guessing based off the message. It's an array containing whatever type Inventory_Hotbar_DirectSlot1Button is

spring skiff
scenic maple
#

Just... Check in the code. Hover over the reference. It'll tell you what type it is. It's really not that complicated.

spring skiff
#

I mean its not a UI Button, it is more like a location-description of this here and I think I must have the option to make arrays in there first, before I am able to make arrays in the code realated to this.

#

Its like the New Input system was never made for putting it in arrays.

scenic maple
#

You can put anything into arrays

#

You have the buttons (or actions, whichever it may be) in code, clearly

#

Just use them there

#

I don't really get the confusion

# 
class YourFunnyClass
{
  private WhateverType[] _buttons;

  private void Start()
  {
    _buttons = new[]
    {
      _controls.Player.Inventory_Hotbar_DirectSlot1Button,
      ...
    };
  }

  private void Run()
  {
    // loop
  }
}
spring skiff
#

The input itself is a bool in my case.
But putting it in a bool array would also need that I would be able to put the "Inventory_Hotbar_DirectSlot1Button" into an array, what seems to not be possible because this is part of the New Input System Map. Its more like a location than a variable. Its different to how you would threat a simple Unity UI Button.

scenic maple
#

Once more, you are supposed to put the button/action into the array

#

Not any kind of bool

#

Wherever you may be getting that from

storage limits are dependent on the remote host you use. github for example has a soft storage limit of about 5 gb for a repository. if you have the resources though, you can always spin up your own git server so you can use as much storage as you need

frank zodiac
#

Why do people sometimes name their variables with an uppercase letter like this? Doesn’t this go against the naming conventions?

image0.jpg
#

Why not just name it “health”

#

Is there a convention for this I didn’t hear of

slender nymph
#

according to the standard c# naming conventions public members should be PascalCase. also that isn't a variable, that is a property

frank zodiac
slender nymph
#

it's not a variable if it has a getter/setter, it is a property. a property is used like a variable but in actuality is a group of getter and setter methods

#

this is why you run into issues with modify the members of a value type you get from a property. such as something like this: transform.position.x = 1; This is not valid because position is a property which means it is a getter method returning a copy of the position

frank zodiac
#

Ohh I see

#

Thanks

how do i connect my lever class to the class i want to interact with ```cs

public string HoverText => "Use Lever";

private float InteractTime = 0;

public void interact()
{
    if (CanInteract)
    {
        CanInteract = false;
        LeverAnimation.Play("lever");
    }

}
void UpdateInteractiontTimer()
{
    if (!CanInteract)
    {
        AnimationClip Clip = LeverAnimation.clip;

        InteractTime += Time.deltaTime / Clip.length;
        if (InteractTime >= 1)
        {
            InteractTime = 0;
            CanInteract = true;
        }
    }
}

void Update()
{
   UpdateInteractiontTimer();
}

}

slender nymph
#

presumably your interaction system is raycasting and checking for an Interactable component, so that's all you need to do. that should then call the interact method

echo sand
slender nymph
#

give it a UnityEvent then you just hook it up in the inspector

#

and just invoke the event at the appropriate time during your interaction

echo sand
#

ah i see, thought i had to make an abstract class or something

slender nymph
#

nah, that's not necessary. using the unityevent will allow you to be more modular here since you can then use this to interact with pretty much anything you want

#

and if the unityevent is public you can even subscribe to it from other objects in code instead of just the inspector. that would allow you to subscribe non-public methods to the event so that the event can be the only thing that calls those specific methods

scenic maple
burnt vapor
#

Of course you can, you just have to accept that Unity hasn't done it with their exposed variables

#

You can still do it fine with your own code

scenic maple
slender nymph
#

fields are variables. they are class level variables

burnt vapor
#

A variable is a general term. In C# they are more specifically called a field (when part of a class scope)

scenic maple
#

I might accept "instance variables"

burnt vapor
#

It literally means "a value that can change"

slender nymph
#

a field is literally just a variable that is declared directly in the object. it is a variable. calling it a variable is not wrong. my point before was that properties are not technically variables, they are a set of methods that are used like variables

scenic maple
#

The nuance and naming is difficult around this

slender nymph
#

it's really not. a field is literally defined as "a variable of any type that is declared directly in a class or struct"

burnt vapor
#

To be specific on variables; in C# we call them a field when it's on the class scope and a local variable when it's in the method scope.

scenic maple
#

Mhm

#

Like if you say "declare a variable on the class", I wouldn't be entirely sure if you mean a field or a property

#

They're both "variable"

#

An auto-property, you could argue, is a "variable"

burnt vapor
#

A property is not a variable, it doesn't hold a value

#

While it might look like it does, it will use a backing field most of the time. This means the backing field is the variable in this case.

scenic maple
#

It effectively does through the backing field

slender nymph
# scenic maple An auto-property, you could argue, *is* a "variable"

it's still got a separate field that is assigned by the getter and setter, it's just implicitly created by the compiler instead of explicitly created by the coder.
if you want to be pedantic about what is and is not a variable, then you should not be referring to properties as variables

burnt vapor
#

And yes, this is often reason for confusion

burnt vapor
scenic maple
#

It's a bit petty to make that distinction

burnt vapor
#

How is it petty? There's a clear difference, you're just confused by what syntactic sugar allows here

scenic maple
#

Heh, I'm not confused, I know C# inside and out

burnt vapor
#

If that didn't exist, you'd have to explciitly declare a backing field each time.

#

Then surely you'd understand why a property is not an actual variable being mutated each time

scenic maple
#

Just imo

#

Especially because I don't think fields should be public. If I'm meant to add a "public variable", I'm adding a property

#

Which is where I come back to unity not being able to conform to these standards, you can't use properties in the inspector, right?

languid spire
#

so you have a self imposed 'standard' and you wonder why others do not conform to you

slender nymph
#

you can serialize a property's backing field, either by targeting it with the attribute target for an auto property, or just serializing the explicit backing field

scenic maple
languid spire
#

yes it is 'I don't think fields should be public' is self imposed
