From the image it does seem like it increments with 1 in the logs for each press?

nova python
#

it should do yeah

#

I have no idea why it's not incrementing the second time I press Jump but for the rest it will

#

1st Press: Counter = 1

#

2nd Press Counter = 1

#

3rd Press: Counter = 2

#

4th Press: Counter = 3

@hollow stone Wait, I think it's possible that my spherecast is hitting my own player. If I put my player on it's own layer and exclude it from what you are allowed to grapple on to, would that prevent the spherecast from hitting my own player?

did u try testing that on its own to see if it was the problem?

I had a somewhat similar issue once

#

@hollow stone Yay it worked! Thanks so much

#

oh my b

#

that is so weird

#

the error is prrobably coming from somewhere else then

#

maybe you have something somewhere modifiying a public variable that it is not supposed to modfiy

#

that wouldnt really make sense tho since its all in 1 method

nova python
#

yeah

#

That's the only place it's been modified

#

wait no I'm wrong

#

when the player is grounded the index is set back to 0

#

During the jump the raycast is still hitting the ground and sets it back to 0 I bet

hey guys i am struggling so hard setting up a database in unity does anyone have some suggestions? I tried mysql but the app for it was to much so i switched to firebase got around with the website easily but anytime i go to write code for auth functions it keeps saying my app is not found and ive re downloaded the sdk have the auth installed and my json for google

How do people make thumbnails from images on a device? Because it seems like reading the entire image file is overkill when it's a large image and I only need a small sized graphic for the thumbnail.
I'm making a UI for selecting images from a camera roll

Im trying to make a setting in my game where I can drag and drop ui elements to allow my players to customize the hud in the way they want it to look, so I am using a mousepointtoray but it doesnt detect ui elements, is there a way to allow that?

ionic socket
#

typically you'd use camera.Main.ScreenPointToRay(Input.MousePosition) to draw a ray from your camera into the 3d space calculated by your mouse position.

#

also make sure to check into the drag/drop handers, IPointerDragHandler and it's sublings.

okay thank you

I have a script which lets me drag objects with the script attached around in a grid-like fashion where they snap to coordinates of a particular "cell size" increment. heres the code https://hatebin.com/nalqhcnupz - unfortunately, this has an issue where every time I adjust the location of an object, it comes closer and closer to the camera, and theres no way to move it "backwards" to where it originally started. Does anyone have any suggestions for how I could go about fixing this? either a video showcasing an alternative system or some way I can manipulate the camera to avoid this little issue altogether? Any help appreciated, thanks

Okay, got a solution working!

using System.Runtime.CompilerServices;
using System;

namespace EffortStar {
  public class RuntimeCache<TKey, TValue>
    where TKey : class
    where TValue : class
  {
    ConditionalWeakTable<TKey, TValue> _table = new();
    Func<TKey, TValue> _calculate;

    public RuntimeCache(Func<TKey, TValue> calculate) {
      _calculate = calculate;
    }

    public TValue Get(TKey key) {
      if (!_table.TryGetValue(key, out var result)) {
        result = _calculate(key);
        _table.Add(key, result);
      }
      return result;
    }

    public void Clear() => _table.Clear();
  }
}

using UnityEngine;

namespace EffortStar {
  public static class AimInfoCache {
    public static readonly RuntimeCache<AttackActionConfig, AimInfo> Cache = new(GenerateAimInfo);

#pragma warning disable IDE0051
    [RuntimeInitializeOnLoadMethod]
    static void Initialize() => Cache?.Clear();
#pragma warning restore IDE0051

    static AimInfo GenerateAimInfo(AttackActionConfig config) =>
      config.CalculateAimInfo();
  }
}

Simple enough I guess, and prevents any unwanted changes persisting between runs.

#

erm how do I set the material of a mesh at runtime? I'm calling mesh.materials[i] = myMaterial but it doesn't seem to change the default value

ionic socket
#

mesh.material = MyMaterial works for the first entry in the list; but does not work when I use the indexed reference.

copy to temp array, change the material in the temp array, assign it back to the mesh

Are there any downsides to using the Enabled flag on scripts that don't update but I'd like to be able to turn on and off? They're reacting to other game events.

and "theres no way to move it "backwards" to where it originally started" isn't exactly accurate

but perhaps your code right now doesn't allow for it

I have an Object instance, Most things I assign to it are Monobehabiors/components, as I need the GameObject reference they are on so I cast them to Component, but I tried to put a GameObject as the Object and I am getting a cast exception. Is there something else I can cast Object to that would allow me to get the GameObject it is related to(aka itself if it is a GameObject)?

fluid lily
#

I mean I think GameObject would be the only thing not supported that could be assigned from editor so I can do a check for it.

#

for jumping Im using add force but its super inconsistent with the amount of force idk if its because i press the space bar multiple times during the jump or what

#

what is the best workaround or should i just set the velocity

somber nacelle
swift falcon
#

jumpforce = 1

somber nacelle
#

okay well for one, i'd recommend just calling the IsGrounded method once per Update rather than twice, there's literally no reason to call it more than once. but it is possible that you are being considered grounded for one or more frames after applying the force. What I normally do is I only check for ground when Y velocity is at or below a certain threshold, then reset the grounded state to false as soon as i jump so that it doesn't start checking for ground again until the object has started descending from its jump

#

also if you just want a single impulse of force you should consider using GetKeyDown instead of GetKey, this will also help prevent the object from applying the impulse force for multiple frames in a row

#

Is there a better way to get component of a triggered object, instead of using getcomponent in OnTriggerEnter()
??

somber nacelle
#

TryGetComponent in OnTriggerEnter

elder temple
#

But won't it run like every frame?

somber nacelle
#

no? OnTriggerEnter only happens when an object initially enters the trigger

elder temple
#

Ah...I thought it ran every frame

#

😅

#

Tnx

somber nacelle
#

even if that were the case, how else would you expect to get a component if all you are given is a reference to a Collider?

#

Yeah..i thought there's a different way which I don't know of

fresh cosmos
somber nacelle
#

it is an event that you subscribe to. do you know how events work?

fresh cosmos
#

yeah, i added the event from basic c# class with [InitializeOnLoad] and added a test method to it in its constructor

#

it logged that it should have added the method to the event but it never logged that it triggered

somber nacelle
#

show the relevant code

fresh cosmos
#

hold on let me find it

somber nacelle
#

also are you certain you don't want to be using either RuntimeInitializeOnLoad (since the event you are subscribing to is only invoked during Play mode or in a build) or using the editor version of the event instead?

fresh cosmos
#

oh, that might be an good idea

#

looks like i dont have the code on my laptop but i can rewrite it real quick its just a couple of lines

    private static Scene _previousScene;

    SceneChangeDetector()
    {
        _previousScene = EditorSceneManager.GetActiveScene();
        EditorSceneManager.activeSceneChanged += onSceneChanged;
        Debug.Log("Added to event");
    }

    static void onSceneChanged(Scene previousScene, Scene newScene)
    {
        Debug.Log("Trigger");
    }
}

Using NavMesh, is possible to add path restrictions to specific agents (not specific agent types, but specific instances of an agent)?
I would like for example: to disallow a specific agent from getting outside some rectangle(s).

Show what you have attempted?

#

With a grid do you mean some sort of array or some grid component?

#

GridLayout?

thick plume
#

Does anyone have an idea why I'm able to instantiate the gameobject, but as soon as I try to add it to the list, I get NullReferenceException? I have no idea what could even try to figure it out

        ...
        static public List<GameObject> level;
        
        void PlaceItemOnScreen(Vector3 mousePosition)
        {
          ...
          GameObject gameObject = SelectedItem.selectedPrefab;
          gameObject.transform.position = prefabPosition;
          Instantiate(gameObject);
          level.Add(gameObject);
        }
#

the prefab gets instantiated as expected, it appears on my screen, but as soon as it tried to add to the list it errors

main shuttle
thick plume
#

sounds like an idea

#

ty

timid meteor
#

so this is just the part of the code that refers to the generation of terrain

#

what I am trying to do is

#

move the grid that generates the terrain via code

#

in the line

#

Vector3Int SpawnHere = new Vector3Int((int)SetGridPosition.transform.position.x, (int)SetGridPosition.transform.position.y, 0);

#

SetGridPosition is a gameobject that I assign a cube to that will make the grid active once the player has entered into the trigger box

#

the problem I am having is

hexed pecan
timid meteor
#

finding where to put SpawnHere

#

So knowing this how would you approach this?

hexed pecan
#

The GridLayout component is probably a good choice if you want to do conversions

#

Or anything grid based

timid meteor
timid meteor
hexed pecan
#

GridLayout can be used with code

hexed pecan
#

Calculate the offset with SetGridPosition.position - pivotPos where pivotPos can be your first grid position or whatever you want

timid meteor
#

hmmm ok I'll take a look into it thanks 😄

swift falcon
# hexed pecan Yes

here is what I attempted

using UnityEngine;

public class HideObjectsInCollider : MonoBehaviour
{
    private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Player")
        {
            foreach (Transform child in transform)
            {
                child.gameObject.layer = LayerMask.NameToLayer("Ignore Raycast");
            }
        }
    }

    private void OnTriggerExit(Collider other)
    {
        if (other.gameObject.tag == "Player")
        {
            foreach (Transform child in transform)
            {
                child.gameObject.layer = LayerMask.NameToLayer("HiddenObjects");
            }
        }
    }
}
#

@hexed pecan what do you think?

hexed pecan
#

Do you mean to just hide them or disable them?

#

Also what object is this script on, is it the one that other objects enter?

#

Why would it hide its own children? Im confused

tepid river
#

i have this interactive (mini) map i built and now i wanna draw more information as text into the scene. whats the proper way to have text anchored to 3d objects?
i read you can make a canvas and glue that to the object, but i smell that this might be overkill?

vagrant blade
#

Just child it to the object

thorny spindle
#

You can also worldtoscreenpoint it

#

if you want to really put it on the canvas

tepid river
#

well i dont care about the canvas. i just want to anchor a bunch (20+) texts to different transforms

hexed pecan
tepid river
#

final

thorny spindle
#

oh, then just child it

#

But you'll probably want to make sure the text always faces the player

tepid river
#

so attach a canvas with a UI text to each object?

#

afaik UI texts need a canvas to work

vagrant blade
#

You can use the 3D textmeshpro object as well, no need for a canvas.

tepid river
#

cool thanks 👍

thorny spindle
#

Also I have a question

#

If in a game I have a bunch of items that I might want to add to later in some update

#

How would I take care of that list

#

like if I had a list of swords somewhere with sword1, sword2, sword3

#

But I added a sword4

#

How would I make sure that gets added to the list of swords so that I can iterate over the list to show in a menu later or smth

#

And how would I even add the sword?

hexed pecan
#

Where does that list live?

thorny spindle
#

Would it be an addressable asset that I push in an update or smth?

#

I haven't made any of this yet lol

#

This is just a problem I suddenly thought of, since I've never considered stuff like updates to a game after release

#

I guess.... would it make sense for the list to live in a scriptable object?

#

But then I would need access to the sword prefabs for instantiation at some point, so maybe it'd have to be a monobehaviour?

#

I guess I could have it be a scriptable object or smth, and then match the string of sword list and the prefab names and then something else in game could instantiate from resources

hexed pecan
hexed pecan
thorny spindle
#

Yeah, but I'm worried about how live updates would affect everything I guess

#

But I don't know how those work at all

#

Maybe that's what I should study next

tepid river
#

cool the TextMeshPro was exactly what i wanted.
cant believe how obsolete my "central canvas that imperatively positions UI images to screenpos of worldobjets" was

thorny spindle
#

Henlo to you too

#

i even resized the canvas images to simulate 3d space size differences catcrymic

How sus is a singleton that tracks state?

tepid river
#

uh depends. in my old project, the GameServer and GameClient were Singeltons

hard sparrow
#

I don't know anything about multiplayer or servers yet

#

(hoping to delay that since I know it will be very hard)

tepid river
#

best to just post your class, so we can smell it together

#

👃

hard sparrow
#

Well it's a status effect manager that can take a generic status type and matching enum to add a status from a list of prefabs to the specified unit

#

I figure I'll end up using FindObjectOfType on it most of the time anyway

#

How often do you guys use FindObjectOfType (or equivalent) ?

tepid river
#

if its a singleton, you dont need to find it tho.
just give it a public static MyClass instance

hard sparrow
tepid river
#

i try to avoid anything like Find. never use it.
but im not a gamedeveloper and not used to even have the ability to search for instances by class

swift falcon
#

Find isn't that bad : D

#

unless ur scene tree is HUGE

polar marten
#

if it isn't important that they are legible, you can put the text meshes in world space

hard sparrow
#

I'm using it a lot when implementing particular derived classes that implement and handle their own implementations - they find the classes they need and call the methods they want

polar marten
#

it is also sometimes, but rarely, expensive to render another camera. make sure your camera is configured correctly by putting all this stuff on a layer, and turning off unused features

hard sparrow
#

But then I think, if I'm using Find like this maybe I might as well make some of these managers singletons...

#

But THEN I think, well if this is my thought process I'll just end up making every manager a singleton, and that can't be right

tepid river
#

my former roommate did a unity project for his bachelor, and had almost no coding experience. so instead of properly managing a tree of references, he just had a ton of scripts and objects floating around somewhere and used search everytime.
THAT was a codesmell

#

a lot of managers are singletons by nature, doesnt mean you have to build them as such

hard sparrow
#

I think my architecture is pretty good. But it's not like I get any feedback on it so who knows

tepid river
#

also its kinda pointless to hand down a reference to your WorldManager or whatever into every single tiny object.
a public static getInstance() is much better

hard sparrow
#

K I'll just make it singleton. Might as well learn by doing

swift falcon
#

hence why DI is used for stuff like this but for some reason nobody in game dev which is making a client uses DI

tepid river
#

whats DI

rich girder
#

hello can somebody help me

swift falcon
#

dependency injection library

hard sparrow
#

DI?

swift falcon
#

It autowires the dependencies

hard sparrow
#

I heard from professional game devs that DI in gamedev is pretty pointless

swift falcon
#

.e.g.
Lets say you had

MyComponent(MyMenuManager manager)

#

It will autowire inside the object

rich girder
#

hello can somebody help me

swift falcon
#

so u dont need to deal with the object lifetime

swift falcon
#

THIS IS A HELP CHANNEL

#

DI is pretty nice for decoupling logic

hard sparrow
swift falcon
#

its not used at all unfortunately

#

in every part of software development we generally use DI

#

to wire up constructor dependencies

#

You can use stuff like myDiContainer.AddSingleton<MenuManager>()

#

then it'll automatically resolve it

#

when myDiCotainer.Dispose is called it disposes all the services

tepid river
#

not a fan of dependency injection mostly. it hides a lot of things and makes understanding stuff more difficult.
still has its usages oc

swift falcon
#

So u dont have to handle the lifetime

#

the beauty of the DI is u dont have to handle construction or lifetime of the object

hard sparrow
#

I would need to see an example to understand

swift falcon
#

tbf nothing that the client uses

#

for some reason people dont use DI in game clients

hard sparrow
#

When I was learning to code (explicitly for purposes of game dev) I spent like two weeks trying to understand DI, not really succeeding, and then never using it anyway after hearing some gamedev pros trash talk it in gamedev context

swift falcon
#

for game servers its a differen story 🙂

#

In enterprise DI is used for nearly every large application

#

except in the gaming industry for game clients.

#

better examples

hard sparrow
#

What are the kinds of situations where you start thinking about using DI?

swift falcon
#

When you have a huge amount of dependencies in your services which can change, or when you have dependencies and you dont want to manage their lifetimes and creation yourself

mental lava
#

if im using unity on Linux, is it recommended to use vs code? if not, what other alternatives do you guys suggest

hard sparrow
#

"dependencies which can change" as in a class depends on a certain class at one time, and a different class at a later time?

tepid river
#

VSC works well on linux (for my work, dont know about unity)

swift falcon
#

.e.g.

MyConstructor(MyDependency dep) {

}

MyDependency(AnotherDependency1 dep1, AnotherDependency2 dep2) {

}

Now normally without DI i will need to do:
new MyConstructor(new MyDependency(new AnotherDep1(), new AnotherDep2()))

With DI you can just do:

serverProvider.GetComponent<MyConstructor>()

#

It will new up the objects automatically

#

and handle them

#

ofc u need to register them .e.g.
serviceProvider.AddSingleton<AnotherDependency1>();
serviceProvider.AddSingleton<AnotherDependency2>();
serviceProvider.AddSingleton<MyConstructor>();

hard sparrow
swift falcon
#

you can see the benefits right here.

swift falcon
#

Ability to easily change out deps is a nice one

#

now whenever you reference IFileSystem in a constructor it will automatically resolve the correct one registered in the DI

#

maybe I need to restart unity

tepid river
swift falcon
# hexed pecan Do you mean to just hide them or disable them?

either is fine. The script I posted would be attached to the collider. It's to hide enemies, other players, and objects on 2nd and nth floors of buildings while the player is on the lower floors in a top down game. The approach was to have a tag or layer for hidden objects and add and remove objects from that tag or layer as they enter or exit the trigger. Maybe there is a better way?

hexed pecan
#

Well the script is hiding/showing its own children instead of the one its colliding with, so I'm not even sure if it works correctly

swift falcon
#

that's probably why it doesn't work or do anything

#

because it can't parent itself to objects dynamically... How can I make it so that it works on collision / trigger enter and exit

Hey, I need to sort small lists (usually 1-20 elements, rarely above 30) extremely efficiently. The keys are positive floats. They tend to be near-sorted a lot of the time so the default quicksort used by List.Sort() may be the bottleneck, and I'm looking for a better algorithm for this scenario.

Here is an example of a typical list:

[14.43493, 65.56322, 172.989, 213.8974, 257.5395, 324.424, 346.906, 357.6949, 368.1883, 0.2753617, 0.419436]

As you can see the list is almost sorted, except for the last two elements which are at the wrong end. It is quite common for the list to be made up of some number of ordered subsequences. As such, what is the most efficient sorting algorithm for this? I am thinking of using Insertion Sort but it does not take advantage of the subsequences being sorted. I would prefer one which splits up the list as such and re-orders the subsequences based on their first and last element, and handles overlaps appropriately:

[14.43493, 65.56322, 172.989, 213.8974, 257.5395, 324.424, 346.906, 357.6949, 368.1883], [0.2753617, 0.419436]

Does something like this exist? Would handling overlaps be too big an overhead?

Question! I'm positioning a bunch of walls right next to each other with this line of code:

wall.transform.position = previousWall.transform.position + -1 * previousWall.transform.up;

The issue is that they are getting spawned/positioned directly next to the previous spawned-in wall while the wall is moving. This leads to some inconsistencies on where the walls actually get spaced. How can I ensure that they are always directly next to each other (no space between)?

image.png
#

Note: If the walls are not moving, they spawn in correctly. I think its an issue with the previous wall moving a pixel or two during the calculation of the next one.

You could try rigidbody.position instead of transform.position

#

Im assuming youre updating previousWall to be the newest wall after creating it?

# cunning sleet What do you mean by caching the position here?

it would seem that there is a mismatch between position and actual position. As you are using physics then this would indicate a mismatch between Update and FixedUpdate positions, so you have a choice, move your code to FixedUpdate or cache the FixedUpdate position and use it in Update

What is going on with my compute shader, why are the alpha maps being tiled like that?
I have 8 terrain layers and the compute shader sets the alphamaps for the terrain using a texture2d to find the closest color from the terrain layer diffuse texture, but its not working the way its intended to work.

The 1st image its how im getting the result from the GPU, and the 2nd image is how im getting the results from loops in C#.

hi guys I'm stuck on a current issue with coding a shotgun that uses raycasting to give it an accurate and randomized spread; it can randomize it's point however I'm using a trail renderer to imitate that it's actually shooting a projectile. I'm trying to figure out how to still draw a trail even if the raycast is unsuccessful; by trying to use the direction of the ray but it's not working - if anyone has a realistic method of going about implementing this, it'd be heavily appreciated. the current code is:

        private void ShotgunFire()
        {
            for (var i = 0; i < shotgunPelletCount; i++)
            {
                var accuracy = Random.insideUnitCircle * shotgunSpreadSize;
                var dir = new Vector3(accuracy.x, accuracy.y, 1f);
                var sprayDir = transform.TransformVector(dir);
                Debug.ClearDeveloperConsole();
                Debug.Log(accuracy);
                var ray = _playerCamera.ScreenPointToRay(Mouse.current.position.ReadValue() + accuracy);
                var targetPoint =  Physics.Raycast(ray, out var hit) ? hit.point : -sprayDir * 30f;
                TrailRenderer trail = Instantiate(bulletTrail, shotgunSpawnPos.transform.position, Quaternion.identity);
                StartCoroutine(SpawnTrailAlternative(trail, targetPoint));
                switch (hit.transform.tag)
                {
                    case "Enemy":
                        var collidedEnemy = hit.transform.gameObject;
                        collidedEnemy.GetComponent<EnemyController>().TakeDamage(shotgunDamage);
                        break;
                    case null:
                        break;
                }
            }
            CurrentAmmo--;
            if (CurrentAmmo > 0) return;
            _playerInventory.ExpireWeapon(_playerInventory.CurrentCard);
      }
#

I've also tried it with this

                var targetPoint =  Physics.Raycast(ray, out var hit) ? hit.point : ray.direction * 20f;
#

however it doesn't shoot straight ahead and instead either to the side or behind the player

Saying "Help" with absolutely no content to what problem you're having is difficult to answer.

#

I have a [SerializeField] Camera worldCam; but when I try to add the camera it doesnt let me

void basalt
#

That's a beginner question pal

elder jay
#

my bad

plucky karma
elder jay
#

its a camera though

#

it does have a camera component

void basalt
#

drag the component in, rather than the gameobject. If that doesn't work, just grab it through C#

#

Camera myCamera = GameObject.Find("someObjectWithCamera").GetComponent<Camera>();

plucky karma
elder jay
#

ill try that

#

because dragging it just does nothing

void basalt
#

Then you're doing something wrong

elder jay
#

thats what Idk what Im doing wrong

void basalt
#

Screenshot your object with the camera

#

the hierarchy view.

elder jay
#

Im trying to drag the main camera

void basalt
#

Which object is your camera component on

#

oh nevermind

#

Just drag the main camera on to your variable

#

If that doesn't work then you need to screenshot the inspector view of the variable

elder jay
#

when I drag the camera in, it lets me but then it doesnt add the camera

void basalt
#

I'm not much help. I don't drag stuff in, I usually just initialize through C#

#

Sorry

#

I think to drag stuff in, it has to be in the same hierarchy

#

Like you can't drag a camera from your scene inspector hiearchy, into your asset in your asset folder

elder jay
#

hmm

void basalt
#

But that's weird because your game controller is in the same hierarchy view

elder jay
#

yeh

void basalt
#

Make a new camera in your scene inspector view

#

right click -> new camera

#

try with that

elder jay
#

I tried that

#

it did the same thing

void basalt
#

restart unity?

elder jay
#

tried that

void basalt
#

Just out of curiosity, change [SerializeField] Camera worldCam; to public Camera worldCam;

same thing

It's probably not the case here, but an OnValidate that immediately nulls the reference could do something like that.

Though from the video, it looks like it's not letting you drop it in. It's got the crossed circle when you hover over the reference field

In this case they might have a class called Camera in the project.

So it thinks the object you're dragging in DOESN'T match the reference field's type

Try this, see for sanity checks?

[SerializeField]

public Camera Cam

Change all of your camera reference to use "Cam" instead.

Refrain naming your class with an already existing class name, how is it that you haven't receive any compiler errors?

If you ever need to make your own scripts that have the same name as UnityEngine stuff, put it into a namespace to avoid ambiguity

Something awfully suspicious here, if that was the case.

Why do all Mesh.SetTriangles overrides take a submesh? If I use 0 for the submesh will that apply to the single mesh?

#

For SetVertices we have:

public void SetVertices(Vector3[] inVertices, int start, int length, Rendering.MeshUpdateFlags flags = MeshUpdateFlags.Default);

#

Because Unity's meshes are made of of a single vertex array and any number of submeshes (indices into that data)

#

If you only have one submesh in the first place, then yes, 0 is the single mesh

Hi, i want to make a plane with the shape of my Field of View

using UnityEngine;

public class ViewportQuad : MonoBehaviour
{
    public Camera camera;
    private float distanceToCamera;

    private MeshRenderer meshRenderer;

    private void Awake()
    {
        meshRenderer = GetComponent<MeshRenderer>();
        distanceToCamera = 0.5f / Mathf.Tan(0.5f * camera.fieldOfView * Mathf.Deg2Rad);
        UpdateQuadSize();
    }

    private void Update()
    {
        UpdateQuadSize();
    }

    private void UpdateQuadSize()
    {
        if (camera == null || meshRenderer == null) return;

        float aspectRatio = camera.aspect;
        float screenWidth = Screen.width;
        float screenHeight = Screen.height;

        float quadHeight = 2f * distanceToCamera * Mathf.Tan(0.5f * camera.fieldOfView * Mathf.Deg2Rad);
        float quadWidth = quadHeight * aspectRatio;

        meshRenderer.transform.localScale = new Vector3(quadWidth / screenWidth, quadHeight / screenHeight, 1f);
    }
}

can someone tell me what i have to change to achieve that? i dont see my mistake

#

the scene looks like this

quartz folio
#

I don't understand why you're dividing by screen width and height, or why you're calculating the distance if your quad was 1 high?

#

Where do you actually want this quad in space?

#

If it's where it is already, then surely you want to be using the distance it is to the camera at some point? And not just calculating something else entirely

You'll only have multiple scenes if you load additive

vague slate
#

🤔

#

is that supported in runtime or editor only?

unreal temple
#

Runtime!

#

All the SceneManager stuff is runtime. There's an editor version too if you need it

#

But that's quite a different use case.

vague slate
#

🤔

unreal temple
#

?

vague slate
#

that's very interesting

unreal temple
#

isn't it what you wanted?

#

oh wait... "scene load handle"

#

I don't know what that is

#

This is to get a handle to the scene itself

vague slate
#

when you load scene you get operation handle

#

which provides you data about current loading operation

unreal temple
#

Ah, well there cannot be a load handle to the current scene because the current scene would already be loaded

lean wagon
unreal temple
#

I believe the first scene loads before any code runs, but what you can do is have a very lean scene that is your loading scene

#

And put a single script in that that loads your scene in the background

#

I have our company logo/splash in a scene like this

vague slate
#

you can run code at any point of time

#

even before all dlls are loaded

unreal temple
#

Hm. Okay, well I'm not sure how to do that

vague slate
#

through attributes on static methods

unreal temple
#

Like RuntimeInitializeOnLoad?

vague slate
#

yeah

unreal temple
#

Sure.

#

I am assuming here that you're trying to do a loading bar or similar

vague slate
#

yeah

unreal temple
#

Well...

#

You can't do that until you have a rendered frame

#

And you can't have that before the first scene is loaded

vague slate
#

damn, additive scene load is a game changer lol

#

Is that 2021 feature?

unreal temple
#

So I'm not really sure what RuntimeInitializeOnLoad has to do with it

vague slate
#

I'm pretty sure it wasn't here before

unreal temple
#

It was available in 2017

#

So it's at least 6 years old

#

Looks like it was introduced in 5.3

#

So 2015

#

unreal temple
#

Hey hey guys, I've a doubt about which would be the best approach for a zoomable and scrollable 2D grid map.
Explaining a bit of the idea, it would be having an image that would be the background of the map, and the game would develop there. I would have a grid to create events on certain points of the grid, create NPC movements etc.

I have in a certain way a structure for the gridcell already defined (I can provide it, but i don't think it's necessary for what i'm looking for) and some base code.

Here are the following problems i've found so far (And idk how to handle):

If i use an GameObject to hold the image and then use the camera to zoom in and out, it may present some errors when it comes to the Aspect ratios and maybe it could potentially zoom out a lot? (The zoom can be fixed by having an underlay with the same background color as the map.

If i use an image in a canvas, the image can be zoomed (scaled) but the grid won't do the same thing. (Can this be the best way to approach it but handle the zoom + X/Y position of the click?)

Has anyone ever done a grid system in a 2D world that can be zoomed in or zoomed out that could kinda point me in the right direction?

#

well yeah, it seems like that's the only choice so far

Hi guys! What is the best way today of culling UI elements. I want to disable UI element gameobject when it outside of scroll view.

lost delta
#

I am looking for the quickest way to optimize drawing sprites without the overhead of thousands of game objects.
Simplifying the images to tiles and drawing tiles worked fairly good, but I don't get to place them in-between the tiles.
I think going straight to applying pixels to a texture may be even better.

So I tried SetPixels(), on to a separate texture, and only apply it to the screen when it gets through all of the characters. (lets call them goblins) Eventually this will be multi-threaded, but for now I am just limiting the amount of time it has, to keep a reasonable frame rate. It picks up where it left off the previous frame)

Anyway, 100,000 of my little 8x8 pixel image takes about 12 frames to be drawn when formatted as a R8, and also unchanged as RGBA 32 bit. I would expect a performance increase with the shorter bit format.

Does anyone have advice for the fastest method to do this? I would love to be able to push this up to 1,000,000 characters processed, even if I have to slash down the image quality.

Thanks

@lost delta I think when case is 1kk of something rendered then you should look at GPU instancing

lost delta
#

I am sticking to 2d if that makes a difference

frosty pawn
#

@lost delta no difference in result, but I would expect difference in performance. Instancing happens all on GPU side, so CPU not loaded so much. In your case you doing tones of work (1kk coping something to same texture) on CPU and then just 1 simple drawcall on GPU

lost delta
#

hmm... are Tilemaps GPU instanced?

frosty pawn
#

@lost delta guess it's not, because you can use regular material with GPU instanced checkbox disabled. I think tilemaps do some performance tricks though

lost delta
#

lol very small spaced tiles. about one pixel across😅

#

I think that the problem is always not in how many pixels you have but in how many actions your CPU does to render it

There are a bunch of examples, some in older versions of people that have animated sprites in DOTS already.

I mostly haven't used it because I am unfamiliar with it. But my 8 byte array ends up being 8 megabytes when I have 1,000,000 instances, and it is hard for me to imagine using a game object would be more efficient. I suppose the efficiency here is drawing them, not holding their information in ram.

It's not about holding something. It is about all times you rewriting data to texture. If it happens ones or really rarely then ok, that is your case. But if your 1kk goblins will run and jump across the screen, then you will ended up with writing to texture 1kk times.

This was the one I used ~a year ago, the problem that this one only did 1 million, was because the sprites overlapped, which caused z-fighting, which dropped the FPS significantly. When spaced out I got way more. With the new versions of entities, you get way better performance then 0.17, so I wonder how many millions of sprites you could get if you updated this. Anyhow, I think this is a way better approach, at least for the sprite rendering part. You can also go hybrid if you want.

Description

Unparents all children.

Useful if you want to destroy the root of a hierarchy without destroying the children.

See Also: Transform.parent to detach/change the parent of a single transform.

I tried DetachChildren too, but it didn't work

Try setting the parent to null?

That's what I'm trying

Hi! I'm currently experiencing a bug where the rope on my character's fishing rod seems to "lag behind" a frame or so. The rope is made out of a LineRenderer, as well as some kind of gravity simulation for the rope as well as the hook.
I've tried putting the DrawFunction in LateUpdate, FixedUpdate, Update, and OnPreRender. Regardless of the method used this resulted in the same bug, with OnPreRender being the exception where the rope didn't render at all. The rope is also on an overlay camera that only renders weapons. Unchecking "Use world space" temporarily fixes one of the rope segments, but breaks the other.

This code wasn't written by me, so I'm not exactly sure where to start looking to debug something like this. I'd appreciate any help available with this. Thanks!

# slim spruce I understand that, trying to give as much information as possible so I at least ...

right now what is happening is

  1. start of frame
  2. the position of the line renderer is calculated with respect to the position of the fishing rod. at this point in time, the fishing rod's position is still the same as it was in the previous frame.
  3. the player's input is read and the movement is applied to the camera
  4. the fishing rod is repositioned with respect to the camera. at this point, the line renderer appears to be in the wrong place.
  5. render the frame

clearly the order of the LateUpdates are not in the order you want*

lost delta
slim spruce
polar marten
#

well the snippet i described is what's happening

#

i can't see your code, so i don't know which callbacks you are putting this stuff into

#

it sort of doesn't matter

#

the positioning of the rope is strongly coupled to the fishing rod's position

slim spruce
polar marten
#

i don't think it's strange, exactly what i am describing is what's happening

#

this can be easily resolved by moving the code that positions the fishing line points to be after the fishing rod is positioned with respect to the camera

#

LineRenderer itself may use LateUpdate to update the mesh with respect to the points. so if you are doing this all in a LateUpdate, you may have to call a method on the line renderer to update the mesh manually after you have changed its positions

polar marten
slim spruce
polar marten
#

none of that matters

#

the rope is simply strongly coupled to the position of the fishing rod. you have to do that work in the same place

#

it cannot be decoupled like it is now

#

this is using fixed update to move around the points. the camera will be "later" than a fixed update

#

the reason the gap is big is because the camera is positioned on update, where the input is read

#

but fixed update is run before update, so the input is from the previous frame

#

i.e., the apparent camera position read by the fishing rope is the previous frame's camera position, and hence the previous frame's fishing pole position

#

look at my snippet. that is what's happening

slim spruce
#

alright, sorry for asking irrelevant questions. I greatly appreciate the help, really. thanks for explaining this so thoroughly. I'll take a crack at it and come back if I have any more questions.

polar marten
#

am i making sense?

#

you have to find the code where the camera is positioned with respect to player input.

#

After that occurs, you have to calculate at least the first few positions of the fishing line with respect to the fishing pole. it sounds like the pole is a child of the camera transform, so its position will have been updated at that point

#

then you have to apply the positions

#

then your bug is solved

I've got a code that rotates the enemy's gun towards the player so that the enemy can shoot the player. But, the attackPoint (which is at the barrel of the gun) doesn't shoot straight but sideways. and when the gun rotates towards the player the barrel doesnt face the player, instead the side of the gun faces the player.

        Transform attackPoint = enemyGun.transform.Find("attackPoint");
        if (Physics.Raycast(attackPoint.position, direction, out hit, Mathf.Infinity))
        {
            // Rotate the gun towards the hit point
            Quaternion targetRotation = Quaternion.LookRotation(hit.point - attackPoint.position);
            enemyGun.transform.rotation = Quaternion.RotateTowards(enemyGun.transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);
        }

        if (!alreadyAttacked)
        {
            // Attack code here
            Rigidbody rb = Instantiate(projectile, attackPoint.position, Quaternion.identity).GetComponent<Rigidbody>();
            rb.transform.forward = attackPoint.forward;
            rb.AddForce(enemyGun.transform.forward * shootForce, ForceMode.Impulse);
            rb.AddForce(transform.up * upwardForce, ForceMode.Impulse);

The easiest solution might be to use a empty RectTransform as the parent, then you can sort the image and texts both as children - though if "InventBG" is the white square, it looks like another UI element or canvas is infront of it, unless your text color is meant to be grey

ColManager.Instance.scope is the list of all game objects that I'm using for collisions and stuff. Any time a game entity is destroyed, it should remove its reference from scope. That's what Remove is for. However, the issue I'm having is that Scope is being cluttered with null references, which should be impossible and is causing bugs.

#

if Remove was being called, the reference would have been removed from scope.

Is there a way to know if the Animator's Controller is a controller itself, or an override of one? I'm trying to write a script for managing custom animations for stuff like weapons and scripted sequences by just having a few "generic" animations that I intend to dynamically swap during the game, with overrides, and RN it seems that on a startup it gets the initial animator from my character, and not the actual override controller I've assigned to it. So I want to include an "if" statement that checks whether it's an override or not there.

        public void Start()
        {
            animator = GetComponent<Animator>();
            
            RuntimeAnimatorController anim = animator.runtimeAnimatorController;

            animatorOverrideController = new AnimatorOverrideController(anim);
            
            animator.runtimeAnimatorController = animatorOverrideController;

            clipOverrides = new AnimationClipOverrides(animatorOverrideController.overridesCount);
            
            animatorOverrideController.GetOverrides(clipOverrides);
        }

        //    return false;

        if (a == b) { return false; }

        CollisionBox aBox = a.GetComponent<CollisionBox>();
        CollisionBox bBox = b.GetComponent<CollisionBox>();

        float distance = (b.transform.position.x - a.transform.position.x)* (b.transform.position.x - a.transform.position.x) +(b.transform.position.y - a.transform.position.y)* (b.transform.position.y - a.transform.position.y);

        if(distance < Mathf.Pow((aBox.radius + bBox.radius), 2) )
        {
            return true;
        }
        return false;
    }
#

This is the code where the MissingReference is being thrown, in the collision checker.

#

Which makes sense, the collision checker loops through all objects in the scope and uses this to check if the two objects have a collision. The issue isn't that this method fails if there is a missing reference, the issue is that there should never be a missing reference

#

I was pretty sure that the issue must have been from some kink of the Instantiate method that I wasn't aware about, but if that's not it then I have absolutely no clue what could be causing this.

Here's a question

you're doing CollManager.Instance.scope.Remove(gameObject); in Remove

#

but where are you adding things to the scope?

#

I don't see that anywhere

In Start()

# 
public abstract class GameEntity : MonoBehaviour
{
    [Header("GameEntity Vars")]
    public Vector3 direction = new Vector3(0, 0, 0);
    public Vector3 velocity;
    public float speed;

    // Start is called before the first frame update
    protected virtual void Start()
    {
        //Make sure that any GameEntity has a CollisionBox
        gameObject.GetComponent<CollisionBox>();

        //Add to Scope
        CollManager.Instance.scope.Add(gameObject);
    }

    // Update is called once per frame
    protected virtual void FixedUpdate()
    {
        transform.position += velocity;
        speed = velocity.magnitude;
    }

    public virtual void Remove()
    {
        CollManager.Instance.scope.Remove(gameObject);
        Destroy(gameObject);
    }
}
#

GameEntity is the parent class for anything that is in Scope

Also shouldn't you just do:

Hi, I've got an enemy script and whenever the enemy attacks the player its gun rotates towards the player. I Want the robots hand (the one that is holding the grip/handle) to rotate along with the gun so it looks like the robot is actually holding the gun.

Here's my current code which doesnt work and creates really odd rotations

                Quaternion targetRotation = Quaternion.LookRotation(hit.point - attackPoint.position);
                enemyGun.transform.rotation = Quaternion.RotateTowards(enemyGun.transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);
                // Rotate the arm in the opposite direction of the gun
                Quaternion armRotation = arm.rotation;
                float gunRotationY = enemyGun.transform.eulerAngles.y;
                armRotation.eulerAngles = new Vector3(armRotation.eulerAngles.x, gunRotationY, armRotation.eulerAngles.z);
                arm.rotation = armRotation;```

                gunRotation.y = Mathf.Min(gunRotation.y, 24f);
                enemyGun.transform.eulerAngles = gunRotation; 
            }```

this code is just for an ai rotating a gun towards a player

then move on to the next step. there are many things you need to check and that site walks you through all of them

dusty badger
#

i might have messed that up honestly its been a while

somber nacelle
#

well for one you shouldn't be comparing a layermask to a layer directly like that

#

two, if you're going to use layers you might as well go all in with layer based collision rather than comparing the layer ints like that
and three, comparing tags works just fine if you do it right

dusty badger
#

yeah theres the bitshift stuff, same idea

#

thats not really relevant but if youre talking about best practices then you want to stay away from strings whenever possible

i have no idea how i tried inverse kinematics but it made the robot one not work two all bendy

somber nacelle

#

well what im really trying is to basically have the hand move along w the gun handle. I originally tried IK which failed and then realised that i could maybe clamp the gun to 24 degrees (this degree is the max you can go with both the gun and hand while looking accurate), and then i thought i'd move the hand along with the gun too but thats another thing i'll have to try to do

swift falcon
#

ok it kinda works now, that site was helpful

#

thx

Can anyone tell me what's null looking at this?

#

I've tried running debugging but everything seems fine..

#

Will keep on testing things unless someone has an idea!

#

Found it I think!

#

I wish it said which var it is..

neon plank
#

If I call a method with [WriteAccessRequired] inside an IJobParallelFor, what happens exactly? Is the method still called concurrently or Unity will schedule and execute the job in a way that it is only acceded once at the same time?

I have an Audio Manager which holds multiple audio clips / audio sources to spawn and despawn whenever the sound is over.

I need a way to change the music in the audio manager whenever I change scenes and so I was wondering if I can somehow set the audio clip to = the audio source of an objecd named Music. So the audio managers SPECIFIC audio clip for playing music would only ever play the audio of the object Music that is in the scene.
Or if there's a code I can use to change the audio for "Music" in the audio manager

Does anyone know how I can do this or any alternative ways?
I havent been able to find the answer anywhere for hours. I feel like I've tried all I know to do it but I dont know enough.

#

LOL I've been looking through the old messages here to see if anyoen else had the same problem too but I havent found anything yet.

#

(i think, haven't had to do this with exceptions in a while & can't remember if IDE debuggers work the same in unity as it does other processes)

leaden ice
#

Debuggers don't stop on exceptions by default

#

But he knows which line it is so easy enough to drop a breakpoint

stable rivet
#

yup, would be my approach

pale owl
#

Because since it doesnt destroy on load, the audio stays the same.

#

If I were to Stop the music, I'd have to make an entirely new audio source in my audio manager which would mean I'd have like 120 different audio sources in my audio manager. But instead, what I had before I had my audio manager was I'd have an object in my scene which contains the music and plays the music attached to itself. But with the audio manager allowing the music to continue between scenes, I dont wanna lose that so I need a way to perhaps... ... Have an object (MusicObject). In that object is the audio and then set the audio clip in a separate object (Audio Manager) to be = to the audio of the first object.(Music Object).

That way the music wont change on load if the Music object in the scene is the same audio clip, but if its a different audio clip then audio manager will play the new one.

I'm not sure how to do that.

#

If anyone knows audio sources, audio clips or audio managers well, I can share my code. I just really need help 😭

dusty badger
#

im having trouble visualizing this system with the MusicObject so its hard for me to say, maybe someone will get it

#

i feel like you can just have all your audio in one place and then assign audiosource.clip whenever you need to, or dont

#

but again i feel like im just missing what youre trying to do

pale owl
#

Maybe I could idk XD

dusty badger
#

why do you have to make a new audio source?

pale owl
#

Because I have walking sounds, jumping sounds, landing sounds, attack sounds, enemy hit sounds, etc...

#

So the audio manager creates a new audio source and deletes it when the sound is complete

dusty badger
#

i need to stop answering questions on topics i havent worked on in a long time haha

#

but is it necessary to delete the audio source when the sound is done?

pale owl
#

OH wait no I'm saying that wrong

#

My bad

dusty badger
#

you could have a separate audiosource for the music maybe

#

and keep doing whatever youre doing for sounds

pale owl
#

It used to do that

#

Not anymore I got confused

#

So yeah, like you said, it creates all of the audio sources in the hierarchy as a child of AudioManager

#

Looks like this in the inspector

#

I need to find a way to change Clip (under the music at the bottom) when I change scenes to be a specific song for each of my scenes.

dusty badger
#

hmm that example is using a coroutine but i dont think its necessary

#

if you can access the audio source called "music" here at some point in your scene loading logic you should just be able to change the clip right?

#

maybe you have to call Stop() on the audiosource, assign the clip, then call play?

pale owl
#

I'm trying to think about how that would fit into my code. notlikethis

dusty badger
#

hmm well you have to figure out when you want one music to stop and the other play, is it right when you start loading, when loading finishes

#

to keep it simple, maybe just inside your "load scene" function, you assign the clip that you want there

pale owl
#

My biggest problem is figuring out how to get the clip from AudioManager's Music Sound's clip.

#

Thats hard to say

dusty badger
#

public function called SwitchMusic() that you call from the load scene function?

#

SwitchMusic() would be in the audio manager

pale owl
#

Thats helpful 🙌

#

Do you know how to call upon that specific clip?

dusty badger
#

where are you storing it?

pale owl
#

I'll send my code maybe

#

In Audio Manager

#

Script

dusty badger
#

do you have a List<AudioClip> in your audio manager?

#

and you are dragging and dropping all the audioclips from your assets into the inspector

pale owl
#

Yeah

dusty badger
#

then you have a reference to all the audioclips in audiomanager, so you could just do SwitchMusic(int musicIndexInList) for example

pale owl
#

OH! Wait do you mean, list all of them and then choose the int for example if music was 15???

#

Then change the audio clip for 15

dusty badger
#

yep that way the scene loader doesnt need a reference to the audioclip

pale owl
#

OwO

dusty badger
#

although you could also do it that way, you can make that list public and have the logic directly in the scene loader if you wanted

#

its just cleaner to have all that logic in the audio manager

#

and theres other ways to be cleaner too but you can clean that up later

pale owl
#

I think I know what to do then!!!

#

Thank you, I'll try something

How to make c# errors in another thread be thrown into debug console?
because when error occurs there (for example, div by zero) the thread stops and it doesnt print anything into the console

dusty badger
#

they have to be in a try/catch block

#

im not sure if try/catch works in a thread you created yourself actually, if you use C# Tasks you can get the exceptions with try/catch

#

i havent seen if theres a method to automatically do it nowadays that popped up but when i checked a while back you had to do that

I instantiate the same Canvas prefab twice at runtime, one time it has the World Space property [1], which does not appear in the original prefab (which is the desired result, not sure why it works that way). In the second case, it stays as the prefab, with missing options in the Canvas component [2].

image.png image.png
#

(click the images, not sure why discord sized them like that)

simple egret
#

Hm, maybe it doesn't show all options if the canvas is a child of another

#

Which would make sense as only the root can dictate where it's placed and how it's rendered

hi,
is it possible to hide/show some properties on the editor based on enum or a bool ?

simple egret
#

If you have NaughtyAttributes, you can use a conditional attribute. Else, make your own custom inspector

elfin tree
solemn raven
simple egret
#

NaughtyAttribute's docs, online

solemn raven
latent latch
#

I suggest just using naughty's

#

There's a lot of attributes among the conditional attribute that you'll find useful

#

That and it does supply you with some functionality for custom inspector stuff if you do want to create some later

elfin tree
#

Anything wrong here at first glance?

I guess I'll order them in paint, Discord messes it up.

#

Canvas positions should be set using the RectTransform's anchoredPosition, so your anchoring preset is respected

elfin tree
#

I'll check, better version (since i already did it)

image.png
simple egret
#

(Discard if the target position is translated from world space to screen space)

elfin tree
#

Btw I call it an anchor but it's not really one

#

Not sure if relevant

#

But those are all transform.position

#

It's the whole canvas that's moving

simple egret
#

You'll have to explain what you want to do, and what those variables are

Hi, I have a simple question: I have a player with a Rigidbody which in turn has multiple colliders under it (a few for general collision and one to check if it's feet are grounded). I want to know which one of the colliders was hit in OnCollisionEnter(Collision collision). Looking at collision.collider is not right since it's just the thing I'm colliding with, not my own collider. Do i really need to give each collider a separate kinematic Rigidbody and MonoBehaviour just to know which collider generated the event?

elfin tree
#

I guess my thing is hard to understand as is, will keep on testing things!

#

I think all it was was me changing .position instead of .localPositon

dusty badger
#

or iterate through all the contacts

raw relic
#

@dusty badger Ah thanks! I've always just assumed GetContact was to get a basic Vector3 impact point for some reason. I usually don't work too much with gameplay code 😅

What is the best way to debug how a certain list in my code is losing references to game objects?

hey so I just updated my game to newest version of unity and now Im just getting this error message and dont know what it means or how to fix it

thin frigate

I have a "scope" list in my GameManager containing all active game objects of a certain type, and for some reason it keeps losing references to one specific type of game object shortly after they're instantiated. I'm not familiar enough with VisualStudios debugging, help would be appreciated.

I think u can just ignore that, u can restart the editor if u want and it only really becomes a problem if it continues to come back

graceful rampart
#

ya ive restarted multiple times and its been happening for a few days now

#

i cant delete the line of code or anything either

warm wren
#

Have u tried deleting your project's library folder?

graceful rampart
#

i have not

#

ill try that

#

it just gave me more errors and it replaced it automaticly

#

i can ignore it but idk if it will mess with when I finish a build of the game
