[main shuttle]

Yeah, it's called BoxCast

[quartz folio]

Because packages can be updated, and it requires me to only use git flow to push updates. They also support dependencies, and are well isolated by default.
Meanwhile UnityPackages require extra work and have no features.

[main shuttle]

Or BoxCastAll in your case

[misty jewel]

thanks I think that's what I need

[main shuttle]

Since you want all the gameobjects in that box, not just a single one.

[hidden kindle]

So I have a strange issue

For whatever reason, my enemy AI moves just fine in the player

But I built it and in the build version, the AI keeps starting and then stopping

I'll try building it again and see if there was just something wrong with that build

I also get these messages when trying to build

[cedar pivot]

hi i have a problem at my passing system

when i press the button the ball goes to other player but it comes back.

and ball is goes to other player very fast

using System.Linq;
using UnityEngine;

public class Passing : MonoBehaviour
{
    private Passing[] allOtherPlayers;
    private Ball ball;
    private float passForce = .7f;

    private void Awake()
    {
        allOtherPlayers = FindObjectsOfType<Passing>().Where(t => t != this).ToArray();
        ball = FindObjectOfType<Ball>();
    }

    private void Update()
    {
        if (GetComponent<Player>().isHaveBall)
        {
            float horizontal = Input.GetAxis("Horizontal");
            float vertical = Input.GetAxis("Vertical");

            Vector3 direction = new Vector3(horizontal, 0f, vertical);
            Debug.DrawRay(transform.position, direction * 10f, Color.red);

            var targetPlayer = FindPlayerInDirection(direction);

            if (targetPlayer != null)
            {
                if (Input.GetButton("Fire1"))
                {
                    if(targetPlayer.tag == this.gameObject.tag)
                    {
                        GetComponent<Player>().isHaveBall = false;
                        GetComponent<Player>().isControlling = false;

                        targetPlayer.GetComponent<Player>().isHaveBall = true;
                        targetPlayer.GetComponent<Player>().isControlling = true;

                        PassBallToPlayer(targetPlayer);
                        Debug.Log(targetPlayer.name);
                    }
                }
            }
        }
    }

    private void PassBallToPlayer(Passing targetPlayer)
    {
        var direction = DirectionTo(targetPlayer);

        if (direction != null)
        {
            Vector3 ballToPlayer = new Vector3(direction.x * passForce, 1.0f, direction.z * passForce);
            ball.gameObject.GetComponent<Rigidbody>().velocity = ballToPlayer;
        }
    }

    private Vector3 DirectionTo(Passing player)
    {
        return Vector3.Normalize(player.transform.position - ball.transform.position);
    }

    private Passing FindPlayerInDirection(Vector3 direction)
    {
        var closestAngle = allOtherPlayers
            .OrderBy(t => Vector3.Angle(direction, DirectionTo(t)))
            .FirstOrDefault();

        return closestAngle;

        // Non-LINQ Version
        //Passing selectedPlayer = null;
        //float angle = Mathf.Infinity;
        //foreach(var player in allOtherPlayers)
        //{
        //    var directionToPlayer = DirectionTo(player);
        //    Debug.DrawRay(transform.position, directionToPlayer, Color.blue);
        //    var playerAngle = Vector3.Angle(direction, directionToPlayer);
        //    if (playerAngle < angle)
        //    {
        //        selectedPlayer = player;
        //        angle = playerAngle;
        //    }
        //}
        //return selectedPlayer;
    }
}```

idk where is the problem

and the other script

[woeful leaf]

You should not run a GetComponent<> in the Update like that

[cedar pivot]

hmm ok i will try after 5-10 min.

thanks

[woeful leaf]

It probably won't solve your problem, but you shouldn't have it like that

You should cache the player

private Player player;
private void Awake()
{
  player = GetComponenet<Player>();
}

And this as well

[cedar pivot]

i did it

[thin aurora]

Can't help you with the problem. I can help you with your coding style, though.

1. Like Wumpie said, don't have GetComponent<Player>() in your code. Store it in memory when you call Awake.
2. Add guard clauses to your code, to avoid nesting. Instead of checking if (GetComponent<Player>().isHaveBall), check if (!GetComponent<Player>().isHaveBall) and add a return; keyword. This makes your code much more readable.
3. FindObjectOfType and FindObjectsOfType are bad for performance and generally a bad idea to use, as they can easily cause problems. Consider getting your components another way

[tough osprey]

Can I have a variable in a ScriptableObject be another script (not to a prefab) that is of a specific type? I have configuration ScriptableObject that defines how to create variations of a type and I want to define a script that should be added to the GameObject that I'll create at runtime.

[cedar pivot]

thanks @thin aurora & @woeful leaf

im updating my script

[tough osprey]

eg, I could put a script name in the config ScriptableObject and then do something like:

gameObject.AddComponent(Type.GetType("ScriptName"));

But I'd like to avoid using strings and searching and instead directly pass the class/type reference.

[late lion]

There isn't a built-in way to do this, but it's trivial to make a custom serializable type that saves the name of the type as a string, but exposes it as a dropdown in the editor. For example:
https://github.com/SolidAlloy/ClassTypeReference-for-Unity

[normal stump]

is there a unity library nuget package? I want to import in a netstandard2.0 class library to share certain types like vectors

[thin aurora]

No, you should create a Unity project and shape it to be a package

[normal stump]

basically I just want to create models that are shared by client and server

[thin aurora]

I know, I also tried doing this, but there is no point in doing it like this

[normal stump]

why not?

[thin aurora]

I made a multiplayer package and I also tried to do it outside of Unity, but Unity has too many limitations to do this

One simple thing I can think of right now is how Unity can't work with constructors, and how you can't use monobehaviours in general

[normal stump]

I don't want mono behaviours

[cedar pivot]

it goes to the other player, then it comes back

[thin aurora]

You might aswell make a blank .NET Standard 2.0/2.1 project without Unity

[normal stump]

I just want model classes so that the API can communicate

[tough osprey]

Thanks that is exactly what I wanted. Even the inheritance validations. General question on using something like this that has an MIT License, I can pull that package in as a library and use it as is and then sell my final project, yeah? I've been hesitant to use other libraries because I don't want to misunderstand a license or what I may be required to do.

[normal stump]

but I want certain types in those models

[thin aurora]

Try extracting UnityEngine.dll

There's no package that does this

[normal stump]

yeah

thanks will try

[thin aurora]

I believe, since Unity compiled in .NET Standard 2.0, you can also extract your build DLLs from a build and reference those

If you make an asmdef folder specific for API stuff you would get it as a dll

[normal stump]

it's what I'm doing rn

[late lion]

MIT license is one of the most permissive licenses. The only condition is that you include a copy of the license somewhere with your game. It can be just a text file in the build.

[thin aurora]

Probably still requires UnityEngine though

[cedar pivot]

guys i fixed the problem

[normal stump]

well I can just rip some models

no harm there

[cedar pivot]

the problem is

.

[normal stump]

actually it's gonna be a problem there are a fuckton of DLL's

can't import them all

[whole yew]

when clicking on a UI input field, it automatically highlights all the text that was typed in and if you start typing, it will delete everything, is there a way to make sure the text isn't selected so that the user can just continue typing without all the text being deleted?

[thin aurora]

Yes, because dependencies

Usually Nuget or Unity's package manager handles this

Have fun 🙂

[polar marten]

this doesn't really make sense to do

what is your goal?

[polar marten]

nuget for unity and other similar packages do not work very well

[normal stump]

no, I mean I have a class library projects, I want to import the unity dll into it to steal the models

[polar marten]

you can create a project using dotnet project with netstandard21 as the framework, add your package, then publish it. all the dependencies will be gathered for you. you will have conflicts with unity supplied dlls that you can resolve with ignore version verification. good luck

[polar marten]

oh i see

[normal stump]

yeah I figured I won't do it

[polar marten]

this is not practical

you can use the unityengine stub dlls people publish

[normal stump]

I will just make my own Vector3, since it's the only model I wanted

[polar marten]

you can also reference it directly on your system, which will work

[tough osprey]

So I have many layers. Terrain layers like water, desert, grass, etc. Object layers like trees, mountains, etc. Other layers like ChopTreesHere, MineHere, PowerLines, etc (not named those). I also support mods providing definitions and handlers for whatever layers they want to add, eg a Gas Pipe Layer.

Since my game is entirely procedurally generated, I'm not hand crafting anything in the editor. I'm also trying to avoid preconstructing these layers because I don't expect modders to preconstruct anything.

Currently I load all Configurations from Resources, cycle through each Config and build the layer as defined, which includes attaching the referenced handler to that layer.

Does that make sense?

[polar marten]

do you have a screenshot handy?

of your game

[normal stump]

can I use a Task to update gameobjects asynchronously?

[tough osprey]

lol, super early prototype but here. Currently working on Zoning layers which is where the layers start to actually become managed. I can draw previews but working on creating a ChopTrees zone that will be managed.

[polar marten]

looks good

[polar marten]

you can use tasks to more succinctly deal with time and player loops in unity, but you cannot use it to do work on game objects off the main thread

[polar marten]

does the game have to be closed source?

are you sure there is any value in that?

[normal stump]

is there an Invoke method?

to run code on the main thread

[polar marten]

what are you trying to do?

[solid mountain]

hey some help

[polar marten]

i see. you can use unitask to achieve this succinctly. it offers await UniTask.SwitchToMainThread(). tasks are not threads.

[tough osprey]

What do you mean? Other than the hope that I do eventually release the game and make some money from it?

[normal stump]

async Task()
{
  while (true)
  {
    await InvokeMainThread(()=>{ });
  }
}

@polar marten

[solid mountain]

i'm making a rythm game and sometimes unity lags a little when loading and then the moving stuff are late and the music is sounding off

[polar marten]

you can eliminate this cantankerous plugin architecture by simply open sourcing your game

then if people want to make changes they can pull request it to you in github. if they cannot practically use the github UI, they will not be making interesting mods to a simulator anyway

[polar marten]

you can use the thing i said

take a look at unitask

[normal stump]

it's a package?

[polar marten]

yes

[normal stump]

aight

will have a look

[tough osprey]

Oh I see, interesting thought. One counter argument to that is that modding gives players choice. Take the Rimworld community (a core inspiration for my game), there's the vanilla experience and then there's the modded experience. Some mods are loved by some and hated by others. The modding capabilities of games like Rimworld and Cities Skylines is the model I'm following.

[polar marten]

you can always make it a checkbox

anyway, it's your call

[tough osprey]

Also, this plugin model feels right to me, but I'm guessing it's a anti-pattern in Unity

[polar marten]

you are at the start of a long journey

[polar marten]

the rimworld guy had been embedded in the game industry at the right place and the right time for a while before rimworld, and even then i'm sure he would architect it quite differently with the knowledge he has now

[tough osprey]

This feel right to me, no?

MapLayerConfig[] configs = Resources.LoadAll<MapLayerConfig>("");
foreach (MapLayerConfig config in configs) {
    GameObject obj = new GameObject(config.name);
    MapLayer mapLayer = config.AddComponentTo(obj);
    mapLayer.transform.parent = transform;
    mapLayer.Initialize(config, width, height);

    mapLayers.Add(mapLayer);
}

[tough osprey]

Yeah, I'm not following their architecture at all. Having modded that game, I know a bit about their code base, but I'm not following their patterns (I don't agree with much of it). (Not bashing their code, it works really well and is easy to understand, and I absolutely love their game)

[polar marten]

okay well i have shared my perspective.

it is a long journey to

and make some money from it
i am trying to say rimworld guy had already worked on many successful games, at a studio that actually later imploded, so serendipity had a big role

[tough osprey]

Yeah, and as someone with a fulltime job and a family, I temper my expectations already 😛

Still fun to work on and imagine an eventual end. For the moment, just a fun side project POC

[normal stump]

is is bad for performance to get the transform of game objects without caching?

like, do I save a transform field or gameobject field?

[lucid valley]

are you using that for mods?

[leaden ice]

whichever you need more often

if not both

[normal stump]

alight

[leaden ice]

It's actually rare that GameObject is the best type for a reference

usually you're more interested in some particular component on the GameObject

[normal stump]

I see

[tough osprey]

Partly, and also it simplifies my process. I find it easier to create a new resource folder, drop in some textures, define a config, and let my existing code integrate it without needing to create a Tilemap in the editor and configure everything.

[leaden ice]

GameObject is only useful if you want to do something involving the active state of the object or its layer

[polar marten]

i think a lot of this stuff ends up having a crazy ants architecture which is fine

personally i would try to implement as much of the game as possible myself, without any notion of plugins, and once it actually works, pluginify it

[lucid valley]

well, i'm just pretty sure it won't work for modding as the resources folder doesnt exist in builds. Think you'd need asset bundles or something like that, but i've not tried before

[polar marten]

you will not have the wisdom for how to do plugins before a working game exists

[tough osprey]

Yeah, I thought of that. I don't really want modders to even have to create AssetBundles, but I figure this architecture gets me closer to that. Extending this to some other way like AssetBundles is something I'm assuming can be done. (leaving it as an assumption for now)

[polar marten]

that is my polite way of saying that the architecture for plugins is bad

[tough osprey]

Noted, and I appreciate the discussion. I actually found that when I pluginified terrain, adding new terrain layers was so easy. I'm working on the first managed zone (chopping trees) and then I expect other zones (mining stone) to be easy. Attaching screenshots of my grass layer definition (no prefabs or game objects) (yes I'm sure I need to optimize sprite sheets or something like that).

[polar marten]

it's really hard to say

[tough osprey]

I don't mind brutal honesty

[polar marten]

lol

on the other hand, i think i have a hard time seeing a bigger picture here because i don't play rimworld

i played a lot of cities skylines, but then i stopped playing

i never tried modding it

i author an open source game, and it has an audience, and people make the pull requests the way i describe, but end users are authoring text assets

[eternal tusk]

How do i change the y axis of the gameobject without affect the x or z axis

[polar marten]

and i had an a-priori thesis for a moddable (community authored) game that would have an audience, that wouldn't really fit for a city builder

other than the game i made, it would make more sense for (1) a game about shoes, (2) a game about hotwheels/cars

[leaden ice]

be more specific about what you mean by "y axis"

[polar marten]

and actually, boost.ng/rigs of rods is probably that cars game

[eternal tusk]

my gameobject would be rotate around an cube, but i want to change the y axis only

[lucid owl]

could someone help me with a unity project i downloaded?

[eternal tusk]

Red: Rotate around
Blue: Moving y axis.
I want to control what height (Y axis) would the gameobject be rotating.

[lucid owl]

I dont know if its a compatability issue or something, but for some reason specific sound effects dont play and some stats dont display properly

[polar marten]

@tough osprey so basically what i am saying is
unless you have a very strong thesis for why this game would have a modding community... it's best to focus on a simpler architecture that lets you make a really good game. the thesis "popular games attract mods" is much simpler than, e.g., mine, "a bunch of specific stuff about card games that makes a community authored CCG popular as a consequence of it being moddable"

[lucid owl]

It's a program that was showcased around a year or so ago...and for some reason nothing is working to fix it so far

anyone have any ideas what might be the issue?

[polar marten]

do you have a link to the project?

[lucid owl]

https://lowlevellemmy.itch.io/mantis?download

I was hoping to do what they said in the video and add custom voice lines and parameters

[polar marten]

what version of unity are you trying to open the project with?

[lucid owl]

though, i look at the comments and more and more people are noting how it doesnt work

[lucid owl]

i dont have unity, i just open the exe

...i assume that might be a factor

[polar marten]

okay

you might want to ask code beginner

[lucid owl]

well, i assumed it was more of a general issue

[polar marten]

you can download unity 2020.3.25f1 and open the source here https://github.com/LowLevelLemmy/LLL_Mantis

you are on the start of a long and fun journey

it sounds like you are at the very, very beginning of this journey

[lucid owl]

thanks

[zinc parrot]

when a task is created in unity, is it always on a seperate thread or is there a chance it will be put on the main thread?

[leaden ice]

depends how you create the task

[zinc parrot]

oh? I just do this

[leaden ice]

Task.Run will run on a separate thread

[zinc parrot]

ah ok cool

thanks!

[whole yew]

bump

[viscid hull]

sorry for the question but how i do for set somethings on dontdestroyonlaod because my game manager is in the level not in the main menu

and i want to set somethings on main menu

[somber nacelle]

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

also don't crosspost

[vague slate]

Is there a built in attribute that makes callback on Application quit?
I need some proper cleanup callback for statics

[somber nacelle]

not an attribute, but there's a few events you could use
https://docs.unity3d.com/ScriptReference/Application.html

[vague slate]

interesting

thanks

[leaden ice]

Also
https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnApplicationQuit.html

For Monobehaviour

[vague slate]

no mono for me

Allthough I have been using mono bridge

(hidden go)

kinda what I wanted to get rid of in the first place

😅

🤔

it doesn't work in Editor

it seems

[scenic creek]

I'm having trouble with my player movement script. I've been using rigidbody.MovePosition, but I wanted to have collisions work so I switched to rigidbody.AddForce. However this causes my rotation to bug out. I'm using rigidbody.MoveRotation which worked perfectly fine until I switched to AddForce. Now the player will sometimes jitter in rotation.

Here is the new behavior.

[leaden ice]

missing from your description here is your actual code.

[scenic creek]

one sec

Previous behavior.

sd.velocity = Vector3.ClampMagnitude(sd.velocity + acceleration, c.maxVelocity * movementMultiplier);
rigidbody.MovePosition(sd.velocity * Time.fixedDeltaTime + transform.position);

Vector3 upDirection = sd.CalculateAverageUp(sd.attachmentDistance);
Debug.DrawLine(transform.position, transform.position + upDirection, Color.magenta);
Vector3 forward = Vector3.ProjectOnPlane(sd.camera.forward, upDirection);
Quaternion targetRotation = Quaternion.LookRotation(forward, upDirection);

rigidbody.MoveRotation(
        targetRotation
    );

[leaden ice]

This isn't enough context really

where is this running

Update? FixedUpdate?

what is sd?

[scenic creek]

It's a method called by fixed update.

[polar marten]

it's hard to make a rigidbody player controller that works. try kinematic player controller. it is a free and high quality asset

i believe it supports this style of movement that you are going for

[leaden ice]

rigidbody.MovePosition(sd.velocity * Time.fixedDeltaTime + transform.position);
shouldn't this be
rigidbody.MovePosition(sd.velocity * Time.fixedDeltaTime + rigidbody.position);?

plus I thought you said you switched to AddForce

[scenic creek]

ah yes, I accidentally left that part off.

rigidbody.AddForce(acceleration);

[leaden ice]

where?

Why not just share your whole script

[scenic creek]

this would be instead of the first two lines of the previous.

[leaden ice]

If you're doing BOTH AddForce AND MovePosition that'll be somewhat problematic.

[scenic creek]

No, I'm not doing both. I comment out the one I'm not using.

If it's more clear I can do a pastebin

what is the difference between transform.position and rigidbody.position, when the rigidbody is on the same object?

[potent sleet]

no reason not to use the premade kinematic controller

why reinvent the wheel

[leaden ice]

they can be different especially in between physics updates, as the Transform may be interpolated for visual smoothness

[scenic creek]

https://github.com/Supetorus/Bitsy/blob/Movement/Assets/Scripts/Player/Movement/ClingState.cs

[scenic creek]

I'll try that instead.

Actually that's relevant to the previous way I was doing it so nvm

[polar marten]

i think you are on the right track, but also on some hard tracks

like tracks that will make it harder to achieve what you want

[scenic creek]

ok, so advice?

[polar marten]

so when you do something like this

    [HideInInspector] public ClingState clingState;
    [HideInInspector] public FallState fallState;
    [HideInInspector] public JumpState jumpState;

this is telling you you are making something that is tightly coupled

like you can pretend to decouple something by making a class hierarchy and a state machine or whatever

    public InputActionReference move;
    public InputActionReference sprint;
    public InputActionReference jump;

but stuff like this is telling you, well it's strongly coupled

you can't make a strongly coupled thing like movement, particularly idiosyncratic spider wall clinging movement, and turn it into something decoupled

you can pretend it is decoupled

but you can't make it decoupled

am i making sense?

[scenic creek]

Yeah.

[polar marten]

it helps you organize stuff intellectually and emotionally to have these separate scripts

i'm not saying it's bad

but it does get in the way

[scenic creek]

Yeah my purpose was mostly organizational.

[polar marten]

but I wanted to have collisions work
going to your original question, you mean collisions in the sense of confining the character movement naturalistically. like the spider cannot move through walls.

right?

or do you mean the spider should interact physically with something like a swinging pendulum - it would get knocked back by a conventional unity physics object

[scenic creek]

so what I have right now will keep the player from going through walls only to a point. Once it is going fast enough, like when I press sprint, then it will clip right through.

So yeah, the first one about going through walls.

[polar marten]

okay

can i step back one more time?

i think it is valuable to try to author this yourself for education purposes and to make innovative movement

and we'll talk about the techniques to scale up to support innovative movement

unfortunately, it involves, for the most part, reinventing the https://docs.unity3d.com/ScriptReference/CharacterController.html for your specific needs

it's about understanding how this works

it's worth looking at this asset

https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131#content

@scenic creek i'm going to go ahead and fork my default multiplayer sample here - https://github.com/appmana/appmana-unity-starter-hdrp - and import this asset

[gaunt cobalt]

Hello all, Does anyone know how to select an AR object using Unity AR foundation and then an AR text panel appears? the panel also needs to dissapear after i click on the AR object again. I tried looking for tutorials online but there isn't really anything on this. I only started coding so im slightly struggling on this

[polar marten]

you're on the start of a long journey

would specific tutorials be helpful? what is an example of something you want to make

[gaunt cobalt]

i want to create a info button object, when selected using raycast, an text panel appears with instructions

[west lotus]

An Ar object is like a regular object. You would raycast from the screen position of the tap into the scene, detect a hit and do what ever you like after that. So you should start with how a tutorial on how to fire a raycast from touch input and detect a object

[gaunt cobalt]

then when im done reading, i can make it dissapear by selecting the info button again

[scenic creek]

I'll look into using the kinematic controller. I didn't think anything that was prebuilt would work for what I'm doing since it's pretty different movement from a lot of games, but I'll see.

As for the moment, is there any way to fix my jittering issue with a quick fix?

[polar marten]

@scenic creek so based on the KCC source, you will be reimplementing, using raycasts, a character controller

[distant glen]

Why is OnMouseEnter() or OnMouseExit() not being called?

[scenic creek]

So is there any way I can fix my current jittering issue without rewriting my entire game?

[leaden ice]

does your object have a collider?

Also are you using the new input system or the old one

[distant glen]

Yes, it's instantiated in the code

[distant glen]

I didn't install any packages. I'm using whatever input system that comes with 2021.3.16f1

[leaden ice]

should work as long as nothing is blocking it and your mouse is actually over the collider

what kind of object is this

is it in the game world, or is it UI?

[distant glen]

It's in the scene, not UI

[teal delta]

hey there, how can i make bool true after one press of a button and after another set it to false (like a switch)

[somber nacelle]

myBool = !myBool

[teal delta]

thanks

[polar marten]

hard to say without reading all of your source and trying it myself. i think you have to do this one on your own

[scenic creek]

I think the only part that should be relevant is the part I posted. That entirely controls the movement and rotation in those lines.

[distant glen]

Does anyone know what these build errors pertain to?

They've suddenly began.

[simple pike]

How would I get a position of a collision ?
I have a bomb that can be dropped and I'm trying to create an explosion at the impact point
how would I achieve this ?

[somber nacelle]

you're using the UnityEditor namespace in code that isn't editor-only
(second error)

[distant glen]

Got it, that fixed everything, thank you

[normal stump]

how can I get the angle required to face another Vector3 from a Vector3

[leaden ice]

to - from``` will give you the direction vector.
An "angle required to face" is quite a vague concept.
You'd have to define that better, like "The number of degrees around <some particular axis> required to rotate from the current heeading to a heading facing the target"

[potent sleet]

OnCollisionEnter should give that information

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

[hard sparrow]

If you have a conditional shader that you want to be able to turn on and off, do you fold that into your normal shader and have a bool for it, or do you make a second shader and add it as another material on top of the normal one when you need it?

Er, no, apparently you can't use bools to control shaders. You have to swap between materials or add new materials

[misty jewel]

just to be on the same page
I think this involves converting 2D rectangle to a 3D box by raycasting each corner of the rectangle?
or is there a built in method that lets me convert a 2D rectangle on screen to a 3D box on the ground ?

[misty jewel]

I realized if I raycast corners and convert to a box it would require also scaling the box to be bigger/smaller when it's further/closer to the camera which adds a lot more complexity that I dont know how to calculate accurately

[main shuttle]

It depends on your game. If you have an orthographic RTS camera like AOE2 then you wont need to. If you have a perspective camera, there are instances you need to do what you say. If you would just look down on the map perpendicular, you could also skip that. If you have a perspective camera at an angle, it might be more useful to draw an invisible cube that represents your selection box, that has the vertices changed so that the box starts small and gets bigger at the end.

[misty jewel]

mine is a perspective camera at an angle
So I should maybe do a cube that looks like this...?

[main shuttle]

https://youtu.be/OL1QgwaDsqo?t=681
I think you want something like this. Maybe follow that tutorial.

Yeah exactly.

[misty jewel]

thanks I was looking for videos but didnt find what I needed

[main shuttle]

Well if this is what you wanted, then BoxCast isn't the way to go. This isn't a box anymore 😛

[misty jewel]

yea it's warped...

[main shuttle]

More like a pyramid.

[misty jewel]

probably

that gave me an idea
but video first

initial idea is to have a pyramid box collider but will see the video first

[main shuttle]

Well the pyramid is warped too, that's the fun thing about perspective

[misty jewel]

yea...

[long fox]

Any advice to start learning coding for vr

[leaden ice]

learn regular Unity first

then throw in VR stuff when you're comfortable with the basics

[long fox]

Alr done

[leaden ice]

then take a few VR tutorials to learn the basics of VR

[misty jewel]

I feel uncomfortable when he uses the same name for a local variable and a class-scope variable

i went back 5 times to make sure i'm not insane, it was confusing

[main shuttle]

Well the idea is good, not saying the execution was fully correct 😛

But I have seen this style in other videos too

[misty jewel]

also he casually made this array int[] triangles = { 0, 1, 2, 2, 1, 3, 4, 6, 0, 0, 6, 2, 6, 7, 2, 2, 7, 3, 7, 5, 3, 3, 5, 1, 5, 0, 1, 1, 4, 0, 4, 5, 6, 6, 5, 7 };
without saying why it is like that

[main shuttle]

That's just the first one that came to mind. Also, there are a bunch of examples on stackoverflow

Well he sort of explained that part with the box before he wrote that

[misty jewel]

yes sorta

[main shuttle]

0, 1, 2 = a triangle, 2, 1, 3 also, 4, 6, 0 too etc

[misty jewel]

now i get the pattern in the array

[main shuttle]

Is there still a part you don't get?

[misty jewel]

he added vector2 + vector3 * float
which is fine for him but an ambiguous operator for me

[pine horizon]

does something the supports the .net standard 2.0 imply that is also is compatible with the .net framework or no?

[main shuttle]

Can you show your code?

[polar marten]

is your goal to create a frustum-style selection box for RTSes?

[misty jewel]

yes

[main shuttle]

But corners is a vector3 array?

[polar marten]

okay. unfortunately doing this in a general way is pretty complicated. you can try this package: https://github.com/pointcache/UnityFrustum

[misty jewel]

hmmm I messed up then Ill back track

[polar marten]

this is authored by someone on this very discord

[misty jewel]

Thanks for the suggestion

[polar marten]

i know you said pyramid, but the reason this maybe has been a struggle is because the shape you are looking for is a frustum

[rustic rain]

would abstraction be helpful in unity

[misty jewel]

right

[jovial parcel]

anyone know how to use ImmutableDictionary/List/Array in unity? when i try to use it, i get "unable to access internal class" even though i have using System.Collections.Immutable; at the top

[polar marten]

immutablelist is not available in .net standard 2.1

[polar marten]

what is your objective? .net standard 2.1 is newer than .net framework 4, and it is roughly a subset of .net framework 4's core libraries

they are strictly not compatible, but usually they are

[jovial parcel]

ahh bummer

Is there a way to tell if a texture in a material has changed from script?

[dense arch]

Why do the Unity docs refer to IL2CPP as a virtual machine?

The term seems to be loosely defined but I thought it implied run-time handling of an instruction set like the .NET CIL, if it's done at compile-time then it's just a compiler

Or maybe if there is enough run-time abstraction on top of things like memory, it's still considered a virtual machine?

[leaden solstice]

Which document refers IL2CPP as VM?

[dense arch]

Mono and IL2CPP’s scripting virtual machines (VMs)
https://docs.unity3d.com/Manual/performance-memory-overview.html

Unity’s managed memory system is a C# scripting environment based on the Mono or IL2CPP Virtual Machines (VMs).
https://docs.unity3d.com/Manual/performance-managed-memory.html

[leaden solstice]

Yeah seems like it is referring it VM as language runtime that manages memory and resources

[coarse lion]

Any ideas on why transform.Translate jitters? This is the first time I've had it behave this way.

-The translation is handled in FixedUpdate, everything else is Update.
transform.Translate(Time.deltaTime * player.walkSpeed * movement);

-walkSpeed is consistent and unchanging
-movement is consistent and unchanging (ex. moving left results in Vector2(-1.00, 0.00))
-Time project settings are unchanged from default (0.02 fixed timestep, max timestep 0.333..., timescale 1)
-Based on one forums answer, I've tested with Auto Sync Transforms both enabled and disabled, there's no difference.

[uncut lintel]

Guys, I found out how to properly obfuscate code so nobody will ever be able to read/steal it.
-Don't use obfuscation tools
-Ctrl+A to select your entire script and "Join Lines" to convert your entire 15,000+ lines of code into 1 line.
-That's it, you win.

you can write your own language then dont let anyone know how to use except you, you win (satirer)

What can write to the albedo gbuffer? I am displaying just the albedo gbuffer texture
and its not just albedo
its like albedo affected by metallicness

using the gltf importer shader

[polar marten]

this is pretty arcane

you have exceeded our knowledge

[zinc parrot]

sorry was being stupid
its combined in the diffuse albedo and specular albedo

[polar marten]

okay

it was a very strange question

[zinc parrot]

got it in my head that diffuse albedo was just albedo, not just diffuse albedo

[polar marten]

albedo is albedo. math is math.

[zinc parrot]

yes

my thoughts exactly

[elfin vessel]

C# question: How do I tell if a Type is a string or an int?

I cant do a typeof on those

[mellow sigil]

in what context

[leaden solstice]

Why

[elfin vessel]

I've got a function, that turns a Type into a string. For most Types it will be just the name, but I have a few special cases for string, float, int, etc

it's for an editor tool

not a plugin. it's, a utility

[leaden solstice]

And why can’t you do myType == typeof(string)

[elfin vessel]

oh. well. i can... do that, yeah. A switch statement was giving me nonsense so I thought i couldnt do it. I may need to go to bed. Thanks

[leaden solstice]

You can’t use typeof for switch case bc typeof does not count as compile time constant. However you can do type pattern matching with actual object

[plucky inlet]

Ha, just tested another case, already ran into an issue 😄 Nvm, I delete that

[thin aurora]

Indeed, that's not how it works lol

[marsh barn]

Hi Everyone 🙏
I want to create a referral programme in my android app that i'm developing in unity. The android way of referrals uses the Play Install Referrer Library to retrieve the information of the referrer if the app is downloaded using a referral link from playstore. I'm not able to find out how to do this in unity. Found some plugins in asset store but they don't seem to frequently used or maintained. Would highly appreciate some expert advice on how people do this in their Android/iOS apps.

[leaden solstice]

Not a good way. Types in different namespace can have same name.

Type’s name is not a type

[plucky inlet]

This attitude tho 😄

[leaden solstice]

How are you gonna use nameof for full name? Lol

[plucky inlet]

He will ignore any suggestions against his solution, so, dont keep trying 😉

[leaden solstice]

Oh it’s okay my goal is not convincing him

My goal is to show that it is a dumb idea so no one else do that

[thick gale]

when you update a game, does it change the save json that is in place? Or is there something you have to add to your json save that makes it stay even when the game gets updated?

[plucky inlet]

Not sure what you mean? what json, where does it come from?

[thick gale]

I have a json save script, It saves on a button, it loads when the app starts, But I was wondering if it will clear the json when i update the app, I save to the path Application.persistentDataPath + "/saveFile.json"

[plucky inlet]

If you do not remove the app, it will keep the json file because its in an extra folder outside of your app source

[thick gale]

alright, sounds like a uninstall will clear data then yes, which I would expect it to

[plucky inlet]

yeah the OS will remove all relevant data if you delete the app. onAndroid I think it even asks if it should keep the app specific userdata or not. not sure baout that tho

[thick gale]

I will have to test that, thank you for your time twentacle!

[thin aurora]

No point in joining the conversation if you're just going to throw your opinion around instead of helping.

[leaden solstice]

I already have given a better solution. Either use if instead of switch-case or do type pattern matching.

[brittle sparrow]

What is a good way to approach memory-leaks? I pressed one of my buttons, and it just froze Unity, and in task manager it was like inflating with memory.

[neat lagoon]

you have to just think through your code and try to find the infinite loop (which is what I am assuming it is)

'while' loops are the first place to check

then 'for' loops

[brittle sparrow]

wait infinite loops can cause memory leaks?

[thin aurora]

Unity has a profiler

[thin aurora]

No, it can't

[knotty tulip]

I have 4 toggle options which are part of a group so only 1 can be selected at a time. The behavior works correctly but for some reason the checkmark does not appear when it is clicked even tho it is selected. Anybody have an idea why that might happen?

[neat lagoon]

Well an infinite loop will be the larger concern

I am assuming when you say it "froze unity" that it didn't unfreeze

[thin aurora]

You should check your code for methods that implement IDisposable, and make sure those are handled.

Unless you wrote unsafe code

Then the problem is bigger

[brittle sparrow]

yeah i don't use idisposable

[thin aurora]

A memory leak usually doesn't freeze Unity immediatley

[main shuttle]

Just check your button code. If you click the button and it freezes, the problem is there somewhere.

[neat lagoon]

yeah... but an infinite loop would...

[brittle sparrow]

well yeah but

i have so much inbetween button behavior

[neat lagoon]

can you explain your issue more clearly @brittle sparrow ?

[knotty tulip]

If you are talking to me. I have no code on those buttons just a simple group with with 4 toggles

it used to work before i changed images but I tested the same images on a new one and it worked

[main shuttle]

No I was talking to compile error

[brittle sparrow]

it's nothing much it's just Reset Data breaking

[knotty tulip]

oh sorry haha

[neat lagoon]

yes, but you say Unity freezes and inflates with memory

[main shuttle]

So show the code of that.

[neat lagoon]

does it ever unfreeze?

[brittle sparrow]

actually if it happens with Save/Load data then great i have less code there

yeah posting screenshots

okay cancel! I put a for loop without an i++ jesus

thanks everyone i looked more clearly at my code

sorry for wasting your time

[neat lagoon]

how would that ever unfreeze then?

[brittle sparrow]

yeah..

[neat lagoon]

what do you mean "yeah" holy cow I have asked whether or not it unfroze or not like 4 times lol

[brittle sparrow]

oh

[neat lagoon]

like did it or did it not unfreeze

[plucky inlet]

your integer never increases...

[brittle sparrow]

no it just stayed frozen so I moved down to taskbar

[plucky inlet]

how should it ever reach 2 if you do not set it to i++

[brittle sparrow]

yeah the problem is fixed though

[neat lagoon]

okay yes so the whole discussion about memory leaks was pointless, which is why I was asking

[brittle sparrow]

sorry

[normal stump]

hey

so basically I have a turret, it has an arm and a weapon

when I give it a Vector3 as target I want it to turn at a certain max speed towards the target

how can I get the required angle/rotation in order to face the target?

[neat lagoon]

the direction vector is always (targetPos - currentPos).normalized

and you can just plug that directly into Vector3.RotateTowards

https://docs.unity3d.com/ScriptReference/Vector3.RotateTowards.html

[vague tundra]

@normal stump Vector.Angle or Vector.SignedAngle is something that I'd normally use too

[normal stump]

alright thanks

radian is X or Y?

[vague tundra]

Regarding the max speed, you could look at using Vector3.Lerp, or Mathf.clamp to set a hard limit on the rot speed

[normal stump]

ok

[vestal crest]

Im currently working on how ram works stack and heap and i wonder something. Value types are allocated in stack and reference types are allocated in heap basicly i know this is not true but let me ask my question. lets say i have a test class which inherits from monobehaviour. I declared a private int x = 5; this "x" is allocated in stack or heap? I mean its value type yes should be stack but its in a class so im kinda struggling here. is it allocated in heap now?

im having hard times with heap and stack

[main tree]

Hello, I'm not really good at english so sorry first,
I'm using Photon and I can't give a nickname to player.
This code gives NullReferenceExpection error. I'm sure the object which has this code has Photon View component. What can be reason?
GetComponent<PhotonView>().Owner.NickName = "player1";
User connects to master, lobby and room before this.

[vague tundra]

Class C inherits from class B inherits from class A

I have an object of class B.
I want to check whether the object is also class C.
Can I say:
if(B as C) { //stuff } ?

[quartz folio]

Value types are only allocated on the stack if their lifetime is short. If you're allocating them in a class then that's not the case and they are boxed into the heap

[vestal crest]

when i declare an private int in a class will it be allocated in heap?

[plucky inlet]

If this is C or typeof C I guess?

[plucky inlet]

I think it will be boxed into object

[vague tundra]

Sorry I don't quite follow

[plucky inlet]

you can say if(this is YourOtherClass) or if this.GetType() == typeof(YourOtherClass). not tested, but something like that 😄 intellisense will fix my errors 😉

[vague tundra]

Oh cool that makes sense! Thanks:D

[potent glade]

is there a way to move a game object INSIDE a camera's filed of view (orthographic camera), I want to move my Object to the lower right point of the camera Field of view

[plucky inlet]

you can cast from screenpoint to worldpoint to get the extent maybe

[thin aurora]

This link has your answer:

frontObject.transform.position = Camera.main.transform.position + Camera.main.transform.forward * distance;

[plucky inlet]

in the field of view, not in front...

[fiery warren]

So I have a towerdefense type game. My issue is that I could place weapons on other weapons cell which should be occupied. Here are my scripts for them.
Mainscript is in Update function.

Main Script: ```cs
if (mapManager.IsWeaponArea(mousePosition) && !mapManager.IsOccupied(mousePosition))
{
//My stuff
}

Second script:
```cs
public bool IsOccupied(Vector2 worldPosition)
    {
        Vector3Int gridPosition = map.WorldToCell(worldPosition);

        //This if statement is broken I think, it blocks the player from placing the weapon everywhere except the cell where mouse was during the click.
        //If I remove Input.GetMouseButtonDown(0) I can't place the weapon anywhere.
        if (!occupiedTiles[gridPosition.x, gridPosition.y] && Input.GetMouseButtonDown(0))
        {
            occupiedTiles[gridPosition.x, gridPosition.y] = true; //Mark the tile as occupied
            return true;
        }
        else
        {
            return false;
        }
    }```

[potent glade]

I did read this a bit ago.. they are placingthe camera to see the object not the other way around

wait that is a different page

[thin aurora]

The line I send does the opposite though

[plucky inlet]

They are placing the object in front of the camera, thats not what you want

[potent glade]

yeah I need to know the point of the lower right point of the camera

i am looking into it

[plucky inlet]

Thats what I said. You should check ScreenToWorldPosition and the camera values like clipplanes and/or screen size

[thin aurora]

Can't you just get the bounds of the camera, and do what I showed?

Camera.main.transform.position and you move the object to the bottom right depending on camera bounds

[plucky inlet]

oh my god 😄

[potent glade]

I am looking into it ... my head hurts a little so I am a little slow

[thin aurora]

You're programming!!

[empty hollow]

Hello, I like using if statements as guard clauses, to stop further code execution inside a method if the if statement is true.

However, when trying to do that with an inherited method, it does not seem to work. Regardless of the StartActivity base, code keeps executing in the child class. Can someone point me towards a solution to this ?

[main tree]

.

[vestal crest]

I still didnt get an answer to my question (i cant figure it out either). when i declare a value type in a class, will it be allocated in heap or stack

[main shuttle]

GetComponent<PhotonView>().Owner.NickName
GetComponent<PhotonView>() can be null and then Owner can be null.
Check if your gamobject with this script has a PhotonView, and then check if it has an owner. You can also just add 2 debug.logs in front of that line with these 2 parameters.

[main tree]

I will test this, thanks

[thin aurora]

Because return only accounts for the base method

[main tree]

Yes, the owner is null. But what is the solve of this?

[thin aurora]

If you want this, you should throw an exception instead of return

And try-catch it. The if-statement should not happen with normal behaviour anyway

[thin aurora]

Is it possible owner is null, or should it never be null?

If it's possible to be null, change the line to this:

var photonViewComponentOwner = GetComponent<PhotonView>().Owner;
if (photonViewComponentOwner != null)
{
  photonViewComponentOwner.NickName = "player1";
}

If it's not supposed to be null, you should figure out how it can be null

You can also change your code to this for a clearer error.

var photonViewComponentOwner = GetComponent<PhotonView>().Owner;
if (photonViewComponentOwner == null)
{
  throw new Exception("owner is null!!");
}
photonViewComponentOwner.NickName = "player1";

[main tree]

Well, it can't be null :(

[thin aurora]

I don't know photon. I assume you're missing some settings

[main shuttle]

I'm not sure, I never used Photon, but given the information it would have been either of those 2.
You might want to ask in #archived-networking, some of those people might actually know Photon.

[main tree]

Thank you all 👍

[misty jewel]

Hey I'm using this currently and it's working great
Everything so far worked except OnTriggerExit (but OnTriggerEnter works)
||I read that it could be a bug or a weird behavior where events are raised for children on enter and for parents on exit..||
Am I missing something?

void _OnTrigger(Collider other, bool entering) {
   //Common stuff
  if (entering) ...
  else ...
}
void OnTriggerEnter(Collider other) {
  _OnTrigger(other, true);
}
void OnTriggerExit(Collider other) {
  _OnTrigger(other, false);
}

[plucky inlet]

How do you know, it is not working? No Debug Log I see so far

[misty jewel]

In log it says enter enter enter......
But 0 exit
I didn't include the full code here

[plucky inlet]

Okay, just wanted to be sure bout that. Do you see you exiting the trigger actively, and how are you moving into it? with position or with phsyics movement?

[thin aurora]

You should log what entering equals to. If it's true or false.

Also, where did you read about there being a bug?

[misty jewel]

UnityFrustum generates a frustum-shape mesh collider while drag-selecting with mouse
The mesh collider is set to convex trigger on both objects, with a kinematic rigidbody
The frustum mesh is updated in FixedUpdate (according to the readme)

void _OnTrigger(Collider other, bool entering) {
   //Common stuff
  Debug.Log($"{(entering?"Enter":"Exit")} :: {other.gameObject.name}");
  if (entering) ...
  else ...
}
void OnTriggerEnter(Collider other) {
  _OnTrigger(other, true);
}
void OnTriggerExit(Collider other) {
  _OnTrigger(other, false);
}

[plucky inlet]

If you move it with the mouse, it might just miss the moment, where it exits the collider, cause you ignore the collision

oh wait, not mouse but on fixed update?

how do you move it tho, transform.position or physics based?

[misty jewel]

The movement of the frustum shape is handled by the package
Imagine a 2D rectangle converted to a pyramid

[plucky inlet]

its nice that you explain the setup, but we need to know if its physics based or not 😉 If its just transform.position it, the trigger exit might be missed. Can you , just to test, add a force to the object, so it just flies through the trigger collider?

[normal stump]

it's not working for some reason

I'll ask the question again then

I have this turret

I only want the arm to rotate on the up axis to face the weapon towards a target

how can I get the required rotation for just the arm

I have tried moving the entire thing with quaternions

var direction = (target.position - transform.position).normalized;

// 1st attempt (this moved the entire prefab)
var lookRotation = Quaternion.LookRotation(direction);
var s = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * MaxArmAimSpeed);

[misty jewel]

Oh i went to something different
Yes the object (camera) is placed with position

[plucky inlet]

So I would test with physics movement to see if all collisions get called, because moving a rigidbody with position might just miss your colliders. The enter might just work because on the next frame your collider is inside the other and triggers the enter

[misty jewel]

The other object is placed with NavMeshAgent (position also I suppose)

[misty jewel]

True I suppose I need to use enter alone and somehow detect exit when it stops entering

(accuracy is not vital in my case)

[wispy fable]

How can I invoke a function on the main thread from a background thread and return a value? I'm currently using a concurrent queue to enqueue a command that is dequeued and executed on the main thread, but I'm unable to return a value to the background thread. How can I do this?

[plucky inlet]

thats not gonna work. Entering happens only once. you could check OnTriggerStay

[plucky inlet]

So you want
MainThread
=Call=> BackgroundThreadFunction
=EnqueueToMainThread=> MainThreadFunction
=ReturnToBackgroundThread=> ReceiveFunctionValue ?

[thin aurora]

This is only possible in Unity2023

https://docs.unity3d.com/2023.1/Documentation/ScriptReference/Awaitable.html
https://docs.unity3d.com/2023.1/Documentation/ScriptReference/Awaitable.BackgroundThreadAsync.html
https://docs.unity3d.com/2023.1/Documentation/ScriptReference/Awaitable.MainThreadAsync.html

[misty jewel]

in my case every time I move the mouse (collider moves) as long as im selecting (collider is active)* it calls OnTriggerEnter (logs a million times)

[thin aurora]

Sounds like you want Unity work done on the main thread. You know Unity always works on the main thread by default, right? So unless you explicitly make a new thread, working with an async-await pattern is done on the main thread in unity.

[wispy fable]

I have a HttpListener working on a background thread listening for commands. These commands need to execute behaviour on the main thread and return a response

The way I have it set up is that it invokes a strategy which returns a type which is then serialised and send as a response

I'm only implementing the strategy behaviour

[thin aurora]

I would suggest creating a Monobehaviour that you can add Action delegates to in a list, and have this Monobehaviour execute all methods in the list each time Update is called. This is not able to return the value to the thread though.

[plucky inlet]

Maybe show your code if you can. Is it working with Task.Run()?

[thin aurora]

Also, my solution should use a ConcurrentQueue, not a List.

Giving it back to the calling thread is very complex. Not sure if that's possible. You would need to maintain access to the context, which goes over my head.

[wispy fable]

Something like

  public interface ICommandBehaviour {
    public CommandResponse HandleCommand(ICommand command);
  }

On the background thread a HttpListener is running and waiting for requests.
In pseudo; Wait for request, parse request, get response from ICommand, serialize it and respond.

[plucky inlet]

Is there a reason that you have to hop on the mainthread?

[wispy fable]

To access components

I can't access them from outside the main thread

[plucky inlet]

Even if they have been precollected?

[wispy fable]

precollected?

[plucky inlet]

Before you run background thread, do oyu have your components ready?

[wispy fable]

They are referenced if that's what you mean

[plucky inlet]

 private async void WaitForData()
        {
            while (WebRequester.requesting)
                await Task.Delay(1000);

            await Task.Run(() => {
=> This is in a background thread afaik
                Debug.Log(products.Count);
            }); 
        }

So the async void is mainthread, the task.run is background

Correct me if I am wrong 😄

[plucky inlet]

Yeah thats what I meant, but even if not, it should work probably

Just to clarify, afaik, you can not call into a thread itself. You can just call a thread and add events to it so it will run them whenever you want them to be called inside that specific thread

[wispy fable]

It's a server that is running on a background thread, not a client. I've just tried manipulating TextMesh from the background thread and it crashed afaik since no response was received

[plucky inlet]

A server? How do you specify that, are you using netcode or what makes it a server? Just trying to understand your setup

[wispy fable]

It's just a simple HttpListener

I have a component which starts the listener on a background thread

[plucky inlet]

Okay, then just make your mainthread call your events list and feed it with the background thread?

[thin aurora]

Don't use async void

Use async Task and handle the process

async void is going to crash your system as soon as anything goes wrong

[plucky inlet]

This was a quick example from my code... the background thread as I mentioned in the code part is only the Task.Run(); ...

[wispy fable]

I'd have to pass the result back to the background thread which is the issue

[plucky inlet]

Same for the background thread, have a list of events that updates your values maybe?

[thin aurora]

The problem with this is that you can't go back to the same context. What are you trying to do? Does your listener need something from the main thread that can't be done on the same thread?

[plucky inlet]

you can also have a callback object that just holds a state. This gets send to mainthread, mainthread updates the state and your backgronud could listen for those objects to change. Thats just theory, might work

[wispy fable]

I currently have

// Background thread
public CommandResponse HandleCommand(ICommand command)
{
  commands.Enqueue(command);
  // Somehow return the result
}

// Main thread
void Update()
{
  if(commands.TryDequeue(out ICommand command))
  {
    switch(command)
    {
      ...
    }
  }
}

[plucky inlet]

I guess you gotta go with some object based approach

[wispy fable]

In WPF you can get the dispatcher for the main thread to invoke on there. Is there no such way to do it in Unity?

[plucky inlet]

What is it actually doing for the background threads in your wpf example?

[thin aurora]

I already told you that there is a way as of Unity 2023

Doing this manually is not possible as far as I know

[thin aurora]

☝️

Perhaps you can use TaskScheduler.FromCurrentSynchronizationContext() to get the current context, which I have been hinting about for a while now. Since this goes way over my head I can't give you a solution that uses this, but this seems like a start when it comes to switching threads, since it depends on the thread context.

Perhaps you can use my previous solution of creating a monobehaviour to store a ConcurrentQueue of Action types, and have them accept a context from this method. Maybe the main thread can then send the response back as an object, after a main thread handles this queue.

[misty jewel]

@plucky inlet I ended up using OnTriggerEnter + short timeout delay
Works great for my usecase (accuracy doesn't matter)

So it keeps updating the time while still colliding
And it skips selection if it hasn't collided for x time delay

After a small test, looks great even tho it's not accurate

[plucky inlet]

I had a dispatcher somewhere, ill check later on my scripts 🙂

[thin aurora]

Here is something I made 3 years ago that acts like that dispatcher @wispy fable : https://hatebin.com/tlkbntuldf

[vague sedge]

i need help figuring out if a eulerangles.y angle is between two other angles

for example:
the players eulerangles.y angle is 349

and i need to find out if its between 281 - 101 (which it is) but idk what to write to check this the way i want to

            var from = SplineRotationY - 90;
            var to = SplineRotationY + 90;

            if (from < 0) fromFixed = from + 360;
            else fromFixed = from;
            if (to > 360) toFixed = to - 360;
            else toFixed = to;

            if (player.transform.rotation.eulerAngles.y >= fromFixed && player.transform.rotation.eulerAngles.y <= toFixed)
            {
                player.splineDirection = true;
                Debug.Log("forward");
            }
            else 
            { 
                Debug.Log("backwards");
                player.splineDirection = false;

            }```

this is what ive wrote but im not a programmer so im pretty sure this is wrong

[steady moat]

https://docs.unity3d.com/ScriptReference/Vector3.Angle.html

Quaternion.AngleAxis + Quaternion.Angle also works

[vague sedge]

ill try that, i cant get the railSpline.transfrom.forward i can only get its position and rotation

[steady moat]

Quaternion.Angle(Quaternion.AngleAxis(AngleA, Vector3.up), Quaternion.AngleAxis(AngleB, Vector3.up));

Also, eulerangle is between -180 and 180 if I remember correctly.

[vague sedge]

nah its 0 - 360

but thankyou for the response ❤️

[vague sedge]

im a little confused on how to use this to find out if the players angle is between the 2 angles like i described

angleDiff = (player.transform.rotation.eulerAngles.y - SplineRotationY + 180 + 360) % 360 - 180;
if (angleDiff <= 90 && angleDiff >= -90)
{
  player.splineDirection = true;
  Debug.Log("forward");
}
else
{
  Debug.Log("backwards");
  player.splineDirection = false;

}```

figured it out

[steady moat]

the formula is angleDiff = Quaternion.Angle(Quaternion.AngleAxis(player.transform.rotation.eulerAngles.y, Vector3.up), Quaternion.AngleAxis(SplineRotationY, Vector3.up));

The number will be between 0 and 180

[swift falcon]

Is it possible to loop through each SerializeFields in a Header?

Or rather loop through the Header looking for each SerializeFields

[thin aurora]

You mean the header attribute?

[swift falcon]

Yes

Well the one in inspector

[thin aurora]

typeof(myType).GetProperties(accessorFlags) gives you PropertyInfo[]. Each PropertyInfo has a getCustomAttribute<TAttribute>() method to get the HeaderAttribute. If it's not null, you reached a header. If you want a specific header, you should check the attribute that way.

accessorFlags in this case is the flags to search on. I forgot what they are called. But you should check for instance, and private/public depending on what your properties are

If your serializefields are actually on fields, you should do typeof(myType).GetFields(accessorFlags) instead

[tired fiber]

Guys i need help with code, someone help?

[thin aurora]

@swift falcon what is the exact thing you want from this? I can try and create something

Since it's probably confusing

[somber nacelle]

https://dontasktoask.com/

[tired fiber]

?

[thin aurora]

Click the link

[swift falcon]

I was trying to play around with your response but you right. It is confusing haha.

I have a Header with SerialeFields like such

    [SerializeField] private Button levelOneButton;
    [SerializeField] private Button levelTwoButton;```
etc...

I want to loop through the Header to disable/enable each button

[tired fiber]

there was nothing special?

[thin aurora]

Point is, don't ask to ask

[thin aurora]

Well reflection can do that, but it's very complex as you can see

You should probably create a script that disables them all manually...

But, since I'm bored, I can make an enumerator for you.

[swift falcon]

I'm just unsure what myType and accessorFlags are

[woeful leaf]

Or are you just trying to postpone work :3

[shy heath]

I'm trying to have a component be able to save while in play mode

[woeful leaf]

Define save

[thin aurora]

Well, I'm stuck

And ChatGPT aint helping

[woeful leaf]

Ah, same

[woeful leaf]

F

[shy heath]

what i mean is to save the values changed on a component while in play mode

https://docs.unity3d.com/Packages/com.unity.cinemachine@2.3/manual/CinemachineSavingDuringPlay.html

cinemachine has an implementation for it

that it says can be used for other components

[woeful leaf]

Use Scriptable Objects

If you change a value of a Scriptable Object, it'll be saved after you close the scene

Though this is only in editor mode

Don't try to use it as a save system

[shy heath]

mostly i want to get this to work, but it doesnt work as it claims to

so i want to know if im missing any intermediary steps

[woeful leaf]

I mean it's only for tweaking and later it won't be used anymore right?

Also show the code to see if you applied it properly

And #🎥┃cinemachine might know more

[shy heath]

it might be used as an internal tool

[woeful leaf]

SO can also be used as an internal tool

But I'd check out #🎥┃cinemachine and share your code as well so people can see if you applied it properly

[woeful leaf]

And always ,maybe there are some solutions online

[shy heath]

i tried

there are other solutions for which i might have to adapt their code (which is fine ig, but this will save me a ton of time)

[woeful leaf]

I don't know if this is a "Cinemachine Component" since it just derives from MonoBehaviour, but I don't know much about Cinemachine

[shy heath]

i checked out cinemachine's own base classes

[woeful leaf]

I'd recommend moving to #🎥┃cinemachine

[shy heath]

alright

thanks so much !

[thin aurora]

myType is the class your fields are in. accessorFlags are these: https://learn.microsoft.com/en-us/dotnet/api/system.reflection.bindingflags?view=net-7.0

Apparently they're bindingflags

But I would strongly recommend just doing it manually

Reflection for this is unecessary

[swift falcon]

The way I thought of it is whenever my character reaches the goal I store the index in an int completedLevel. Using that int I enable all buttons up to in completedLevel + 1

Is there another way to do this?

[thin aurora]

I was writing code for this but it's just a lot to account for every problem that could happen with reflection

[thin aurora]

Idk what the buttons are, but that's fine I guess

[plucky inlet]

Just use a list to store it

[thin aurora]

But you should do it manually, and not reflection

[thin aurora]

What do the buttons represent?

Just the completed level?

[swift falcon]

No they're levels

From the main menu

[thin aurora]

But they're only a button that turns on or off?

What happends if they're on?

[swift falcon]

If you click on it it calls my LoadLevel function

[thin aurora]

Right and it's disabled if you haven't reached it yet?

[plucky inlet]

Codewise, they are not levels, they are UI elements that load a level, right? So you can just store them in a list or create buttons depending on the last levels you played. all up to you

[swift falcon]

Right

[thin aurora]

What about having a List<Button> in your class, and store a reference there?

Then you can iterate until the button that should be on

And you can check that by just comparing current index +1 against the level

[SerializeField] private List<Button> _levelButtons;
private void setLevelButtons(int level)
{
  // Disable all
  foreach(var levelButton in this._levelButtons)
  {
    levelButton.enabled = false; // Or whatever the way to disable it is.
  }

  // Enable
  foreach(var levelButton in this._levelButtons.Take(level))
  {
    levelButton.enabled= true; // Or whatever the way to disable it is.
  }
}

Something like this

Then you can also skip levels, and go back

You can't skip levels and keep them disabled, though. That's more work.

[swift falcon]

It's a linear game so it's fine

[thin aurora]

Take in this case only returns up until that level, basically

That's why the loops are basically identical

[swift falcon]

I didn't know SerializeField could make a list, thanks

[thin aurora]

I believe List works. Otherwise it needs to be an array

Arrays works too with this code

[swift falcon]

💯

[woeful leaf]

Lists do work on it afaik

[thin aurora]

Happy days

[floral needle]

Hey guys, I want to be able to construct my damage class via ScriptableObject OR by giving it the specific parameters. Is there a better way to do this or is my approach the best I'm gonna get?

public class Damage : MonoBehaviour
{
    float _amount;
    float _addForce;
    int _tickAmount;
    float _damageOverTimeDuration;
    DamageElement _element;

    public Damage(DamageInfo damageInfo = null, float amount = 0, float addForce = 0, float tickNum = 1 /*...*/)
    {
        // if damageInfo is null Construct with Parameter values ... else :
        _amount = damageInfo.amount;
        _addForce = damageInfo.addForce;
        _tickAmount = damageInfo.tickAmount;
        _damageOverTimeDuration = damageInfo.damageOTDuration;
        _element = damageInfo.element;
    }

[woeful leaf]

!cs

[tawny elk]

You can format your multiline code block with C# highlighting! Just add cs to the start of it. Highlighting example below!

class Fluffs : FluffyCat
{
    public void PetCat ()
    {
        Debug.Log ("Petting Cat.")
    }
}

[plucky inlet]

really depends on your situation. If the values do not change and you want to reuse that a lot, use scriptable objects

[floral needle]

thx xD

[swift falcon]

Is there actually such a function? Or should I just use an if statement on each element to check if the level is before my completedLevel variable?

[thin aurora]

This is a Linq method

🙏

[thin aurora]

Since an array and a List both implement IEnumerable, this method is valid on them

[woeful leaf]

It's not okay to fill a 27 inch monitor lmfao

[thin aurora]

Linq is the greatest shit you will ever learn about

Well maybe not

But it will help

A lot

[floral needle]

I want to be able to choose that in a case by case scenario, Im just wondering if this is the best way to make this "Constructor 2 ways" or if there's a "better"/conventional way to do it

[woeful leaf]

Well you can overload constructors

[plucky inlet]

If thats like a library you want to be able to built from SOs, thats totally fine. But again, if you have like a database, cause your game will be based values from that, its better to use a class that just gets fed. But if its like an item you assign but in your case a damage you assign to something, sure, why not

[oblique spear]

New start, sry for the codeblock. Has anyone an idea how to make this shorter or "better"?
Link: https://gdl.space/yosesixeji.bash 😅

[willow magnet]

Anybody?

[floral needle]

Gonna look into this

Thanks for the help!

[plucky inlet]

if(!vInput)
                {
                    _animator.SetFloat(_animIDvInput, 0, 0.1f, Time.deltaTime);
                }

What is vInput and what is _animIDvInput? is it the same value?

[woeful leaf]

Picks the one based on parameters @floral needle

It's the same as method overloading but then for constructors

[oblique spear]

vInput is a bool varaible if "w" or "s" is pressed. So if there is an input on this axis. animIDvInput is the float value in the animator which changes the animation. I think 1 is walking forward, -1 is walking backwards

[plucky inlet]

cant you just get the float of the axis? as it will always return something, either 0 or whatever value you throw in as input?

so setfloat on the animator all the time, without if statements

[woeful leaf]

Also I forgot to give the variable a name but shhh

[thin aurora]

You're not supposed to use the constructor in a Monobehaviour. Instantiate the Monobehaviour like you're supposed to in Unity, and create an Initialize method. You can also make overloads with this like @woeful leaf mentioned.

[woeful leaf]

Also that

[thin aurora]

i.e.

public class Damage : Monobehaviour
{
  public void Initialize()
  {
  }

  public void Initialize(int val)
  {
  }

  public void Initialize(int val, string val)
  {
  }
}

[swift falcon]

what is Initialize method? Did I skip a part in unity beginner?

[woeful leaf]

No it's just a method he made lol

[thin aurora]

It's a method you make yourself.

[oblique spear]

i could try that. But my questions was more is there a better way to get the inputs of the single keys or do i have to check for every single key with a new if statement?

[floral needle]

Not going to lie, this was my first thought, but I (dreamnt) remembered reading somewhere that you couldn0t do this. In retrospect, that's literally what I see when I ctrl + click on a Method to see the overloads xD

Derp moment

[swift falcon]

just something you Initialize() in awake?

[woeful leaf]

It's also used a lot by just the functions given of C# and Unity

[swift falcon]

oki oki

[plucky inlet]

You can bind keys to your value, so they create an axis which makes you return 1 on W and -1 on S. And than you just ReadValue from the input and get the vector or float for your animator

[plucky inlet]

But this will bind you to a gameobject you put your monobehaviour on to have different dmg components, just keep that in mind

[oblique spear]

will try that, ty

[swift falcon]

I dont get it

[plucky inlet]

If you use monobehaviour, you have to use it as a component. If you just use it as a class, you can create it just for data source that then can be used in your components on the gameobjects.

[swift falcon]

The more I dont get it 🥹

[thin aurora]

You probably want to look into Scriptable Objects

This is a good way to set data. But this is more for oak.

[plucky inlet]

Just think about how you gonna set up your damage on your items. can you explain that? Do you have like a gameobject of a weapon and than add damage component to it, which is what you get with your monobehaviour?

But if you have like a scriptable object item, you could reference a field to the scriptable object damage for example, and from there you just drag drop and create your stuff simpler. But you gotta explain a bit what you want to do with damage

[woeful leaf]

I don't understand the behaviour my code is giving, why would it snap onto it if the pointer is not anywhere near the actual item? Am I just doing something funky with the booleans that I'm not seeing? Here's the code: https://gdl.space/yuhatenaqa.cpp

(Each of those items that you can grab has that script)

[plucky inlet]

Is that UI canvas?

[woeful leaf]

Yes

[plucky inlet]

is the canvas overlay or camera screenspace?

[woeful leaf]

Screen space

nop ovelay

Well it's both

[plucky inlet]

Okay, the problem is, the position of your mouse might not be exactly as where your UI is. Did you try to use WorldToScreen with your mouseposition?

[woeful leaf]

Nope

[plucky inlet]

but transform.position is not what you do on UI

you position it with rectTranform.anchoredPosition

[woeful leaf]

Oh

Lemme see

What's so bad about transform.position then for UI elements

Also I suppose I've to do a GetComponent for it then since I don't inheritely have it

[plucky inlet]

transform.position is usually in 3D space, 1 unit = 1 meter. UI is in pixel based grid, so 1 unit = 1 pixel

[woeful leaf]

hmmm

[plucky inlet]

That is why there are WorldToScreen calculations or ScreenpointToWorld and what not

[woeful leaf]

Righty

[woeful leaf]

And why anchoredPosition over position

Now the position doesn't match the cursor with rect.anchoredPosition = Input.mousePosition;

[plucky inlet]

can you debug log both values?

Cause I guess you gotta set the z value to something to fit it

[quartz folio]

You can just cast, as you already have the transform

[woeful leaf]

What cast would I use?

[plucky inlet]

to cast your transform to RectTransform

[swift falcon]

Are Get Set methods common practice in game dev/C#? I haven't seen them often in tutorials

[woeful leaf]

That wasn't what I asked, like what is the syntax for it

I'd think just (RectTransform) in front of it but that doesn't really work

[quartz folio]

Properties are extremely common outside of gamedev, and still common in it. Proper practice is often overlooked for the minor speed benefit of avoiding the methods

[quartz folio]

Why not?

[swift falcon]

I often get a Missing Reference error when I try accessing a variable from another script. The error goes away when I declare it static, would a Get method fix it too?

[plucky inlet]

((RectTransform)transform).position

[quartz folio]

You need more brackets.
Or you just make a variable on another line

[plucky inlet]

otherwise you would try to cast the position as recttransform

[woeful leaf]

Ah right

[quartz folio]

No. You probably have not set the variable to anything

[somber nacelle]

you need to get a reference when accessing a public member from another object.
how to get a reference: https://www.youtube.com/watch?v=Ba7ybBDhrY4

[swift falcon]

Ah could very well be why thanks

[woeful leaf]

That fixes this issue

((RectTransform)transform).position = Input.mousePosition;

[swift falcon]

I'll watch this thanks! NRE has been the death of me. Sometimes it pops up sometimes it don't lmao

[woeful leaf]

The other thing still isn't fixed though 🤔

[woeful leaf]

(This part)

[tired fiber]

https://gdl.space/dikisemuje.cs, can someone tell me how to fix error: NullReferenceException: Object reference not set to an instance of an object
CraftingSystem.RefreshNeededItems () (at Assets/Scripts/CraftingSystem.cs:186)
CraftingSystem.Update () (at Assets/Scripts/CraftingSystem.cs:116)

[plucky inlet]

So did you debug log your rect position and your input. mouse position?

[woeful leaf]

Just realised it should probably be this instead ((RectTransform)transform).anchoredPosition = Input.mousePosition;

[main shuttle]

craftAxeBTN is null, or gameobject is null

[woeful leaf]

Which does break the position again

[tired fiber]

So what i need to do?

[woeful leaf]

With that the cursor and the object aren't aligned anymore

[tired fiber]

Im beginner so idk

[woeful leaf]

I'll go do that now

[thin aurora]

What line is 186?

and 116

[tired fiber]

craftAxeBTN.gameObject.SetActive(false);

186

RefreshNeededItems();

116

[thin aurora]

This line is not guaranteed to be called before update I believe

[somber nacelle]

#💻┃code-beginner next time.
but you are using toolsScreenUI.transform.Find("Axe").transform.Find("Button").GetComponent<Button>(); to get the reference, it seems like that is probably not returning what you expect. make sure you also scroll to the first error in your console because this line is likely throwing an error

[thin aurora]

But the code is full of these find methods so who knows what it gets

You should get craftAxeBTN in another way

[main shuttle]

But if it wasn't found:

        craftAxeBTN = toolsScreenUI.transform.Find("Axe").transform.Find("Button").GetComponent<Button>();
        craftAxeBTN.onClick.AddListener(delegate {CraftAnyItem(AxeBLP); }); 

I would expect the next line to give an error.

[tired fiber]

So what i need to do?

[somber nacelle]

right but if they are just looking at the last error in the console rather than the first we don't know if that is erroring or not

[woeful leaf]

Debug.Log($"The position of the object is: {((RectTransform)transform).anchoredPosition}, and the position of the cursor is: {Input.mousePosition}");

[main shuttle]

Oh fair, he could have way more errors then this.

[somber nacelle]

screenshot your console while scrolled all the way to the top. i'd bet you'll find errors on different lines there 😉

[plucky inlet]

That looks good to me tho. Can you show your screen on how it looks?

[graceful patio]

i have a couroutine question?

how can u tell a couroutine finished

in C#?

[plucky inlet]

have a function you call at the end of it. there is no like default callback

or use async Task that returns a completed event.

[tired fiber]

I get three errors:

[woeful leaf]

It doesn't capture the cursor so to illustrate it, it's the red dot

When you hold the object it yeets it way off to the right and top

[tired fiber]

1. NullReferenceException: Object reference not set to an instance of an object
   CraftingSystem.Start () (at Assets/Scripts/CraftingSystem.cs:58)
2. You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all
   UnityEngine.MonoBehaviour:.ctor ()
   Blueprint:.ctor (string,int,string,int,string,int) (at Assets/Scripts/Blueprint.cs:18)
   CraftingSystem:.ctor () (at Assets/Scripts/CraftingSystem.cs:26) and 3. NullReferenceException: Object reference not set to an instance of an object
   CraftingSystem.RefreshNeededItems () (at Assets/Scripts/CraftingSystem.cs:186)
   CraftingSystem.Update () (at Assets/Scripts/CraftingSystem.cs:116)

[main shuttle]

Yeah, so that's what I expected 😛

[tired fiber]

So can u help me out?

[somber nacelle]

look at that, the line i pointed out that is likely throwing an error is throwing an error

you need to get a reference in a better way than chaining all of these Find calls

how to reference: https://www.youtube.com/watch?v=Ba7ybBDhrY4

[plucky inlet]

Can you show a screencapture of it? Like how it behaves going around the center?

[thin aurora]

A coroutine has no build in way for this. Coroutines are of type IEnumerator, and these only have behaviour on how to keep going. It has a MoveNext method but this is not for checking if it's finished. You should create a seperate boolean outside the code that turns true once the coroutine is finished.

[woeful leaf]

You mean a recording?

[distant glen]

I have about six different managers in my game.

Only two of these are singletons. This is because my learning resources have led me to the conclusion that the singleton pattern should be used sparesly.

The two classes in my project that implement the singleton pattern are the GameManager and the AudioManager.

The other managers in my game, such as the UIManager, InputManager, and CameraManager, are all passed into my GameManager.

If a piece of code wants to reference certain functions of the UIManager or InputManager, for example, it will do so through certain functions I have in my GameManager, which then references the other managers.

Is this bad design? Should I refactor this, or can I keep using it in this way?

[plucky inlet]

I would keep the main managers all singeltons if possible. So you have full control if you need, but you can still have your gamemanager control states that call the UI

[somber nacelle]

that sounds like a kind of bastardized mediator pattern. you could look into how that design pattern works to clean up your current implementation

[plucky inlet]

Ahhhh, I know the issue, i guess at least. 😄 can you show your prefabs inspector of the recttransform component?

[woeful leaf]

Like the inspector of the object I pick up?

[plucky inlet]

The ui text

yes

[graceful patio]

can i have the docs link for it thank u 😌

[thin aurora]

https://learn.microsoft.com/en-us/dotnet/api/system.collections.ienumerator?view=net-7.0 This? 🙃

Because this is what a Coroutine is basically

[woeful leaf]

It has a collider it's just not shown here

[plucky inlet]

Just for testing. can you take the prefab you instantiate as text, pick that one and set the anchor to this:

[woeful leaf]

It's not a prefab though heh

But I can do it in the code

[plucky inlet]

Okay, whereever its coming from 😄 Just set the anchors 😉

[woeful leaf]

This should be fine right

Or wait I still need pivot to be 0 as well

That did change the position of it

But it's not in the center

Like it used to be with the old way

[plucky inlet]

You mean in the center of the screen? or what center?

[woeful leaf]

Oh the hitboxes are whack now

[plucky inlet]

Oh you mean the center of the UI object?

[woeful leaf]

the cursor holds it to the left corner of the object

Instead of the center of the object

[plucky inlet]

can you try all anchors and pivot to 0.5?

Ah wait, anchors to 0 and pivot to 0.5

that should be correct

[woeful leaf]

That fixes it :D

I still have the first issue though

[woeful leaf]

^

[plucky inlet]

what was the issue again? 😄

I thought it was the wrong position 😄

[woeful leaf]

Hitbox illustrates it better that it does it properly heh

[thin aurora]

Indeed it is

[thin aurora]

Indeed it isnt

[woeful leaf]

No that was an issue of using the Rectransform.anchoredPosition instead of the transform.position I used to use

[woeful leaf]

?

[thin aurora]

It's not ;)))))

[woeful leaf]

That the it still can get regrabbed for some time even though the cursor isn't over the object

[woeful leaf]

That's what the video shows

[plucky inlet]

how do you grab your object?

too many topics going on 😄

Found the link 😉

[woeful leaf]

:D

[plucky inlet]

are you sure you reset your onMouseOver correctly? Did you check those values?

[woeful leaf]

It's kinda hard to check in that case

Because it's not like consistent

I might have to do with this part

    public void OnPointerExit(PointerEventData eventData)
    {
        if (Input.GetMouseButton(0)) return;

        onMouseOver = false;
        oneIsHeld = false;
    }

[plucky inlet]

Just disable all but one and debug log your values of this one

[woeful leaf]

Maybe it somehow exited it without getting the input or smth

Or some kind of mismatch

[plucky inlet]

UI is behind sometimes, so your code might execute again before the UI position is updated

hence the execution order of Update, OnEnable and UI update

[woeful leaf]

Right

How would I best check if that is the case?

[plucky inlet]

Is it intended they flip to your position on pointer enter, not mouse down?

flip => move 😄

[woeful leaf]

There's no Update "type" for OnPointerEnter, so I've to combine Update and OnPointerEnter to achieve what OnMouseOver would achieve

[woeful leaf]

The latter refers to this function, not the boolean

That function doesn't work for my use case though

[polar marten]

@woeful leaf what is the behavior you are trying to achieve?

do you want to be able to drag-to-move UGUI elements?

[woeful leaf]

Yeah

[polar marten]

okay

[woeful leaf]

If you click and hold on it it'll follow your mouse position

[plucky inlet]

you could use ```cs
if (EventSystem.current.IsPointerOverGameObject())
{
Debug.Log("Its over UI elements");
}
else
{
Debug.Log("Its NOT over UI elements");
}

To check for being over UI

[polar marten]

class DragToMove : MonoBehaviour, IBeginDragHandler, IDragHandler {
  public override void OnBeginDrag(PointerEventData _) {}
  public override void OnDrag(PointerEventData pointerEventData) {
   // does not account for canvas scaling. you will have to deal with that
   transform.position += pointerEventData.delta;
  }
}

[woeful leaf]

I was not aware that that existed

[polar marten]

@woeful leaf that's it.

[woeful leaf]

I can try to implement it

Oh

[polar marten]

you can delete

all this other code

[plucky inlet]

OnDrag, is that working for UI objects?

[woeful leaf]

I thought Drag was for like mobile

[polar marten]

you don't need a collider

[woeful leaf]

I have one

[polar marten]

you shouldn't have colliders

if you're not using physics

[woeful leaf]

I am though

[polar marten]

what does @woeful leaf mean by physics?

it isn't going to change the correctness of this script

[woeful leaf]

It has a rigidbody

[polar marten]

okay

are you using physics?

not sure

[woeful leaf]

Yeah it uses the velocity of the rigidbody

And the collision to collide with other objects

[polar marten]

i think you are at the start of a very long journey

[woeful leaf]

;-;

[polar marten]

what is the game?

[plucky inlet]

Oh did not know you can use OnDrag on UI, because it acts like a "collider" already, thanks 🙂

[polar marten]

yes, EventSystem requires raycasts, not colliders nor physics, and GraphicRaycaster supplies eventsystem with raycast information for UGUI

in order for an object to receive OnDrag calls it must also have OnBeginDrag, which is a code smell of this api

[plucky inlet]

just read the docs about UI OnDrag. Good to know for next time!

But well, here you have your solution @woeful leaf just use doctorpangloss code with your positioning of recttransform 🙂

[polar marten]

it really depends what the game is

[woeful leaf]

Let implement it and see what it does

[polar marten]

@woeful leaf
there are three ways to move objects:
1 by changing their transform's position
2 when an object has a rigidbody, moving it kinematically (its velocity is derived at the end of the frame)
3 when an object has a rigidbody, moving it with forces (its velocity is natural)

when you want to move an object naturalistically using the pointer, and the object has a rigidbody, and you want the rigidbody to behave physically and naturalistically (#3), you can use joint drives between the rigidbody and an object whose position is being changed by the pointer's delta

#3 is really complex but you can find a lot of examples online

https://github.com/AppMana/appmana-unity-plugin/blob/fb85cbe9c7c672be5d079ba5c06c8454137c8908/AppManaPublic/InteractionToolkit/Positionable.cs#L99 here is how i do it

[woeful leaf]

Although 3 would be cool to implement, it is not needed, nor do I have the time to implement it. And I don't even know if it'd fit the game heh

Currently it's just 1.

[polar marten]

@woeful leaf what is the game?

well #1 doesn't work if you want physics

[woeful leaf]

I know but I don't have like very "real" physics

The only thing that it has is a collider and a set velocity on the rb

[polar marten]

you are doing #2 then

[woeful leaf]

And also 1.

[plucky inlet]

You can still use the transform.position, if you want to ignore phsyics while dragging. So, I do not think its for us to determine your game here 😄

[woeful leaf]

When you grab an object it uses the transform

But when it falls it uses rb.velocity

[polar marten]

okay

dragging objects around with a pointer in a general sense is hard

this is the script i provide to folks who use my technology, because it is such a common ask and it is so hard: https://github.com/AppMana/appmana-unity-plugin/blob/master/AppManaPublic/InteractionToolkit/ThisDraggable3D.cs

since you don't need a general solution, if you can tell me what the game is, i can make a specific suggestion

just eyeballing it, there's a lot that's sort of flawed about how you architected your game

[woeful leaf]

:(

[polar marten]

@woeful leaf here's an example of this dragging script in action
https://appmana.com/watch/theheretic
you can try moving around the lights, flicking them, rotating the camera, and if you visit on mobile, you can use multi touch

[woeful leaf]

public override void OnDrag(PointerEventData pointerEventData) {
// does not account for canvas scaling. you will have to deal with that
transform.position += pointerEventData.delta;
This appears to banish the objects to the shadow realm

[polar marten]

in order to give you a script that works in your specific case, you have to answer my question what the game is

[woeful leaf]

It's quite a simple game really. You've these passwords that fall down, the passwords that are bad you put in the red box, the ones that are good you put in the green box

[polar marten]

okay

attaching rigidbodies to ugui elements typically does not work very well. it requires understanding way more nuances than you will comprehend. let's pretend the rigidbodies don't exist, since for now, other than for the dropping physical effect which is easy to do in code, you don't need them.

1 set your canvas to screen space overlay
2 then use the script i provide

if you want to use screen space - camera, you can try transform.localPosition += pointerEventData.delta, but i feel like i am just programming this for you and you don't really comprehend yet a lot of stuff

so it really depends what your goals are

[woeful leaf]

both are

[polar marten]

both
?

[woeful leaf]

I've two canvases

[polar marten]

okay well

[woeful leaf]

One is for the passwords

[polar marten]

i think you'll figure this all out

[woeful leaf]

The other is for the rest

[polar marten]

i think you can google "dragging sprites unity physics" and you should probably not use canvases at all. you can use TextMeshPro Text (not the UGUI version) to make the text labels

then it will be more intuitive for you

transform.localPosition will resolve your issues with pointerEventData.delta in this case

[woeful leaf]

I made like everything without googling except the IPointer events cuz OnMouseOver didn't work

[woeful leaf]

This does work now actually

[polar marten]

OnMouseOver is deprecated

[nocturne zenith]

is it possible to make y = 0 while keeping the same rotational axis? on a quarternion

[woeful leaf]

It matches the position instead of yeeting it somewhere3 else

[polar marten]

for that matter so is Input.GetMouseDown

[woeful leaf]

It's older yea

[woeful leaf]

Yeah there's a new Input system I know

[polar marten]

the pointerEventData is giving you all the information you need about the pointer

[woeful leaf]

Anyway thanks for all the help, I'll go expirement a bit with the OnDrag and see what that does for me

[vestal oriole]

Does anyone know if it is possible to convert a .texture2d file to an exr file? Thanks

[main shuttle]

Googling gives me this: https://docs.unity3d.com/ScriptReference/ImageConversion.EncodeToEXR.html

[verbal grail]

Can someone give me a quickie? If I have a worldSpaceMatrix and an offsetMatrix, and I want to subtract the offset, is it as simple as worldMatrix * inverse(offsetMatrix)?

[vestal oriole]

Do you know how I can use this script to convert it?

[main shuttle]

Doesn't the example do exactly what you want? Or am I misunderstanding the question?

[graceful patio]

.env unity?

yk .env file

[vestal oriole]

yes, it does what I need but I don't know how to apply it to my .texture2D file

[main shuttle]

Oh, I thought you had a texture2D in your code and wanted to convert that.
You have a texture2D file, make a texture2D in code, and feed it into that method.

[wicked wagon]

I present you the most inefficient (I think) isometric wall fading. https://streamable.com/thd64x
https://codeshare.io/eVb96b
I have this script attached to every wall. When the scene becomes bigger more walls I will have. What can I do to make it better?

[west elk]

Hi, does OnEnable gets called every time the object is set active?

[west sparrow]

Yup

[whole yew]

guys I have a question,

button.onClick.AddListener(() => DoSomething(CalculateSomething()));

If add a listener to a button like this, which calls a function, and "CaluclateSomething" will return some sort of value. Will the value that is return from CalculateSomething be called when the button is clicked or when the listener is assigned?

[woeful leaf]

When it is clicked

Adding a listener won't execute the method

Only whenever the listener is called
