What's the best way to check if a UI element overlaps any other UI element?

jaunty light
#

In the following code I am trying to flip a sprite based on an enumerator. However the flips don't get applied to the sprite.
Does anyone know what I am doing wrong here?

private void ShowSprites()
{
    List<SpriteRenderer> finalSprites = new List<SpriteRenderer>();
    foreach (var tuple in gameLogic.chosenBlocks.Values)
    {
        finalSprites.Add(AlterSprite(tuple.Item1, tuple.Item2, tuple.Item3));
        slots[finalSprites.Count-1].style.backgroundImage = new StyleBackground(finalSprites[finalSprites.Count - 1].sprite);
    }
}

private SpriteRenderer AlterSprite(SpriteRenderer texture, Flip flipOption, Rotation rotateOption)
{
    switch (flipOption)
    {
        case Flip.none: texture.flipX = false; texture.flipY = false; break;
        case Flip.flipX:  texture.flipX = true; texture.flipY = false; break;
        case Flip.flipY: texture.flipY = true; texture.flipX = false; break;
        case Flip.flipXY: texture.flipX = true; texture.flipY = true;  break;
        default: break;
    }
    return texture;
}

Valid but that's because I updated the code. Just trying to have it functional

knotty sun
#

the obvious thing to do is add some debugs to AlterSprite as you cannot see from that code what exactly is being passed in

jaunty light
#

the returned texture is correct

#

let me send another screenshot

#

Updated the code slightly. Not the most elegant solution either, but got rid of the list.

  int i = 0;
  foreach (var tuple in gameLogic.chosenBlocks.Values)
  {
      slots[i].style.backgroundImage = new StyleBackground(AlterSprite(tuple.Item1, tuple.Item2, tuple.Item3).sprite);
      i++;
  }

#

I supposed it I call .sprite it accesses the source sprite and not the updated one

somber nacelle
#

you do know that the flip variables only affect the sprite renderer and how it displays whatever sprite is assigned to it, not the actual sprite texture, right?

knotty sun
#

beat me to it

jaunty light
#

How do you suggest to go about it?

#

What I wanna do is show 3 sprites in my UI. Each of them altered individually by flipping or rotating

#

but with the same original sprite

Hello, I am trying to spawn multiple rooms randomly and use this code to check and make sure they do not overlap, but it work very inconsistently. Is there something wrong with my logic or should you not try to spawn mutiple rooms and check for overlaps on the same frame?

Hey everyone, I am wondering, if its possible to extent the gameobject class, so I can use a simple toggle method in the UI buttons? I kniow its working codewise, but it is not showing up in the dropdown, which I guess is the issue of it being a sealed class probably?

#

To clarify, I am using this in my extensions class, which is working in other classes of course. Any idea how to get it into the reflection of the UIbutton OnClick events?

public static void Toggle(this GameObject go)
        {
            go.SetActive(!go.activeInHierarchy);
        }

since you aren't syncing the physics transforms and aren't waiting for physics to update then your physics queries won't have the most up to date information once you move those objects.
however it is generally better to generate the layout before spawning the rooms. then once the layout has been decided you just spawn rooms in the correct places based on the generated layout so you wouldn't even need these physics queries.

Currently I'm trying to make a UI object use "OnMouseEnter" and "OnMouseExit" events for objects in world space.

It works fine unless my actual mouse cursor is left over any UI.

What could I change with it to make it detect those regardless of what the actual mouse is hovering over?

private void Update()
{
    Position = new Vector3(_rectTransform.anchoredPosition.x + (Screen.width / 2), _rectTransform.anchoredPosition.y + (Screen.height / 2));

    _colliderHit = GetCollider2DFromScreenPosition(Position);

    if(_colliderHit != null && _colliderHit != _previousColliderHit) 
    {
        _colliderHit.GetComponent<MonoBehaviour>().BroadcastMessage("OnMouseEnter");

        if(_previousColliderHit != null) 
        { 
            _previousColliderHit.GetComponent<MonoBehaviour>().BroadcastMessage("OnMouseExit");
        }

        _previousColliderHit = _colliderHit;
        return;
    }

    if(_colliderHit == null)
    {
        if (_previousColliderHit != null)
        {
            _previousColliderHit.GetComponent<MonoBehaviour>().BroadcastMessage("OnMouseExit");
        }

        _previousColliderHit = _colliderHit;
        return;
    }
}

private Collider2D GetCollider2DFromScreenPosition(Vector2 screenPosition)
{
    Ray ray = Camera.main.ScreenPointToRay(screenPosition);

    RaycastHit2D hit2D = Physics2D.GetRayIntersection(ray);

    if (hit2D.collider != null)
        return hit2D.collider;
    else
        return null;
}

hey guys, when i run code to move transform.position, it doesnt move the instance. but if i disable the animator attached to the character, then it moves the instance

#

when i turn on apply root motion in the animator then it works fine

deft timber
#

probably your animator overrides the transform.position

you set in code

Should I use #if UNITY_EDITOR with Application.isPlaying to increase the performance when the game is played outside of the editor?

tame nova
#

if you have stuff you only want running in editor then that could be useful yeah

#

you can also use the [Conditional("UNITY_EDITOR")] tag on methods

Is there any way to make #if be shifted to the right as the other lines? It's fixed on the left.

Anyone knows what if attributes created with CreateVFXEventAttribute are worth caching ?

gusty aurora
#

Similar question, is it worth caching the System.Actions ?

#

things like System.Action setCoroutineToNull = () => _coroutine = null;

leaden ice
#

Depends on the context

heady iris
#

You'll get less garbage allocated if you avoid creating a new anonymous function every frame

#

Storing it also means that you can subscribe to and unsubscribe from events with it

heady iris
#

(i don't remember if it also happens for event subscriptions, but i'd expect that to be the case)

# 
foo.Bar(MyMethod);

resolving the MyMethod method group produces garbage

heady iris
#

subscribing to an event also generates garbage, but you get even more if you pass a method group

heady iris
latent latch
#

With a little more work you can skip out on EvenAttributes and just do graphic buffers with unmanaged data types reuse the buffers directly

heady iris
#

I stick the callback method into a System.Action<TheResult> field in Awake

#

it winds up producing zero allocations!

heady iris
#

an event has to be a lot more cautious; you can un-subscribe from an event while it's being invoked

spark flower
knotty sun
#

yes, ColorType is not string

#

yes, that is the method signature required

#

yeah, on value changed take the value type of the element so Toggle takes a bool and Slider takes a float

Hey guys I have a questions regarding code structure.
So I have coroutines, some are called only once, some can be called from update.
I have added a bool to each coroutine which represents if a coroutine is active or not.
The problem is, once you have a number of coroutines, it's hard to keep track of each bool and routine.

Is there a better way to do it?

knotty sun
#

A Flags enum could be a better option

rigid island
#

why not store the coroutines inside array of Coroutine[]

#

or list

#

bools seem wild use if you have many

Hey guys, I'm having a lil bit of trouble implementing the rules for the day/night cellular automaton. I have the GoL and Seeds rules working, but for some reason the day/night rules aren't working. instead of showing what it's supposed to be showing, it is a chaotic growth instead. I tried replacing the day/night rules with the rules for the maze automaton, and it did the maze automaton perfectly- so the problem is certainly in the day/night rules. here is a bit of the compute shader with the rules in it: ```cs
if (current.r == 1 && current.g == 1 && current.b == 1)// GoL rules
{
if (GoLcount < 2 || GoLcount > 3)
{
next = 0.0; // Loneliness or overcrowding
}
else
{
next = float4(1, 1, 1, 1); // Survival
}
}
else if (current.r == 1 && current.g == 1 && current.b == 0)// Seeds rules
{
next = 0.0;
}
else if (current.r == 0 && current.g == 1 && current.b == 1)// Day/Night rules
{
if (DayNightcount == 6 || DayNightcount < 3)
{
next = 0.0;
}
else
{
next = float4(0, 1, 1, 1);
}
}
else
{ // if cell is dead
if (GoLcount == 3)
{
next = float4(1, 1, 1, 1);
}
else if (Seedscount == 2)
{
next = float4(1, 1, 0, 1);
}
else if (DayNightcount == 3 || DayNightcount == 6 || DayNightcount == 7 || DayNightcount == 8)
{
next = float4(0, 1, 1, 1);
}
else
{
next = 0.0; // Stay dead
}
}

#

(I hope I didn't just disobey a rule by sharing that much code 😅 )

#

some more explanation is probably necessary isn't it

knotty sun
#

DayNightCount == 6 on both sides does not seem correct. Also !code

hi! i'm having some trouble learning about instantiation. i'm currently working on a flappy bird clone... i've got the pipes moving across the screen but i want to have them spawn at varying heights once they move off screen. my question is how can i have the game instantiate a new pipe at a random height once it moves off screen?

#

currently my game just has the pipes move back to the intial x position when it moves off screen in its movement script

#

but ideally i'd want it to destory and instantiate a new pipe when it moves off screen

knotty sun
#

Instantiate can take a position, I suggest you read the documentation

Nothing I find online works.
I'm already set to VS 2022, tried regenerating project files, deleting library, deleting .vs file, deleting all the project files from the project folder manually, updating VS and VSTU, it just refuses to acknowledge that it's installed.

The one thing I suspect might be it is that I don't have Visual Studio Editor in my package manager, it doesn't show up even when I select All Packages.
I don't know if it's because it's not actually used anymore and the docs are outdated, or if something broke so that it doesn't show up for me.
https://learn.microsoft.com/en-us/visualstudio/gamedev/unity/get-started/getting-started-with-visual-studio-tools-for-unity?pivots=windows

Could anyone maybe check their Packages/manifest.json and tell me what the package id and version for Visual Studio Editor are in theirs so I could try a manual import?

Hi guys, I want to make interaction system, but it making ray only on X axis, not on Y, so it's working not correct, how can I fix it? Ray ray = new Ray(transform.position, transform.forward);

#

I need to change forward, but I don't know on what.

rigid island
#

forward is Z

simple egret
#

If you need to change forward, rotate your object. Currently it takes the local Z axis (blue arrow when you have the object selected) of the object this script is attached to.

leaden ice
#

Depends which direction you want

#

Forward is the object's z axis

gray mural
#

I have an object, which has a BoxCollider2D with the size Vector2.one. OverlapBox detects the object when the point is shifted on 1 to any direction, when the size is larger than ~0.95.
Why such a huge offset? I expect it not to return any object when the size is Vector2.one.

Physics2D.OverlapBox(point, Vector2.one * size, 0f);
humble spoke
humble spoke
#

Y/X

#

or Y/Z

rigid island
#

also this is like 3D game right ?

#

transform.right gives you the X axis of the object

simple egret
#

It does not always "point to the right" of your screen, if the object is rotated for example

#

Don't mix up world coordinates eg. Vector3.right (which always points right) and object coordinates transform.right

If you have all the numbers present in some sort of collection, then you probably could do this by parsing the string though itd really be a lot slower. You could even go as far as defining an operation which takes 2 numbers and does an operation on them, then have a list of these visible in inspector. The real tedious part is gonna be having a lookup from some index or ID to number.
Any option is really gonna be slow in comparison to just defining them all in code and using like an enum to choose which formula to use

you can do like semi parse stuff like building it like scratch using enums

    public void AddItem(int scriptableObjectIndex)

        if (itemOwned != null)

            itemOwned.ItemCount += 1;
        }

        else
        {
            CreateItemData(itemBaseSO);
        }
    }

Can this be improved? It's repeated code, I am getting/creating data from either an index or a SO.

#

The order is basically:
Index -> SO

So if I have SO already, then I skip that part of getting SO by index, but everything else is the same.
The thing is that I want the ability to use both, so an item data can be added, removed, returned by either using Index or itemBaseSO.

#

I can probably just improve it by taking out if itemOwned != null into its own function, but thats about it.

#

Actually even that I cant do hmm, maybe a callback but that seems like an overkill 😛

brave furnace
#

but if you know the scriptable object index, why can't you give it the SO instance?

lean sail
mossy snow
upper pilot
#

Yeah but if I remove int overload, then every script in the game has to get SO from database

#

Which is why I added it

#

oh

#

lol

#

I knew there has to be a simple way lol, thanks I will try that 😄

brave furnace
#

but I agree, the index argument is flimsy

latent latch
#

I give index to my SO

brave furnace
#

I'd recommend rephrasing the AddItem to AddItemFromIndex

latent latch
#

guid rather

#

cause guid is cool

upper pilot
#

I havent gone into guid route yet, its planned, but idk if it will happen for this game.

#

I will replace index with guid eventually

lean sail
#

Some form of ID is fine if this is loaded from file for example. Otherwise I dont really see a case where you'd need to add an item from using a number

upper pilot
#

so the function will be AddItem(string itemGUID)

#

Since this way it prevents errors of using index and saving it as that can change.
But I need to make sure GUID stays unique forever, which is why I havent gone there yet as I have other things that needs to be done 😄

#

Its loaded with Resource.Load

#

I store it in a List and I access it directly from a list by index(not ideal I know, but at some point I hope to use GUID instead, we will see if time allows)

#

This is funny cuz I already did your solution for another script, tho in a different order:

Guess I need a break

your code scares me

#

so if this is how you plan to instantiate the ItemData, maybe create a constructor that takes ItemIndexSO and ItemCount as arguments for it?

I'm following this 2D water tutorial that is just instantiating a bunch of circles each with their own rigidbodies and colliders. I like working with this simple method but the performance cost is kinda bad. I've heard of using DOTS but I want to check in with Unity discord before jumping into that. Would DOTS be the right move for this case?

languid hound
#

That does seem a bit extreme yeah. I personally made a bunch of transform points along the surface with a small circle collider then did the physics myself mostly

#

If something overlapped the point, find the velocity of that something and then displace the point and any surrounding points but gradually make the displacement smaller

#

I did some hacky velocity stuff that was a semi verlet integration sort of thing it's weird to explain

Hey there, in my top down game, I want a weapon pickup to show an info box besides it when the player walks over it/is in reach to pick it up, along with the keybind to pick it up (fortnite as reference). Now one of the problems comes when theres multiple pickups the player steps on. How could I handle that? I don't have any idea on how to approach this info box at all.

rigid island
#

you could make it a WorldCanvas which would take care of easy positioning not worry about scale

#

depends how many you need on screen / look you can yse either like also ScreenToWorld forr regular UI

dense rock
#

I only want one info box at a time

rigid island
#

imo then the same worldcanvas that follows your player just for showing infos

dense rock
#

I'm just wondering if I should make a singleton info box manager and OnTriggerEnter put the pickup on a queue or smth

#

and OnTriggerExit remove itself from the queue. Then the Manager could take only the first one in the queue to display, right?

rigid island
#

yeah you can check in trigger what it is

dense rock
#

wdym check in trigger?

rigid island
dense rock
#

exactly, thats what confuses me 😅

rigid island
#

its up to you , do you want it based on distance or your player's FOV / Dot

dense rock
#

probably just distance

rigid island
#

doesnt fortnite show only the info box when cursor is on the actual mesh of floor item

dense rock
#

just want when the player stands ontop of a weapon item, it shows the info to pick it up.
Don't know how to handle that

dense rock
rigid island
dense rock
#

thats an interesting approach, I'll think about that :)

rigid island
#

You could also just use a Physics Overlap

#

which reiqures no rigidbody on trigger or item

dense rock
#

do you have an idea how to handle when he stands ontop of multiple?

rigid island
#

sort it by distance

dense rock
#

i mean the player will have a rb anyways

rigid island
#

store them in an array

rigid island
dense rock
#

uh okay, so add it to an array and sort it everytime one is added?

dense rock

sorry to ping you again, got some issues :')
How do I convert them from Collider2D[] to IPickable[]?
Do I sort them with some sorting algorithm or should I use Linq?

[SerializeField] private float pickupRange;

    [SerializeField] private IPickable[] pickups;

    void Update()
    {
        Collider2D[] cols = Physics2D.OverlapCircleAll(transform.position, pickupRange);

        cols[1].TryGetComponent(IPickable, out IPickable pick);
    }
rigid island
#

IPickable was an example lol make your specific class, didn't mean you actually copy that exact class

#

also try get is a boolean it returns true if component is found and stores it in the variable pick for example

barren patio
#

so a got a issue that i need fixing

dense rock
barren patio
#

is there a way to rotate a transform to have the same up as a ray cast normal without needing to manipulate euler rotation y?

rigid island
#

Layermasks for the Overlap

dense rock
#

alright, but the converting with a for loop is fine? I feel like there is a better alternative method that i just dont know about, but am probably wrong

rigid island
#

they are not very expensive for a handful, unless you start doing crazy amounts of work with more than thousands of iterations

#

and even then.. checking for component is nothin

barren patio
#

🗣️

dense rock
#

Thanks ^^

rigid island
dense rock
#

out of my knowledge too

rigid island
# dense rock Thanks ^^

if you want to improve performance Iwould suggest learning the nonalloc version of Overlap

barren patio
#

when you ray cast you can get a normal right, i want a transform to match that normal but without it affecting the y axis of the euler rotation

rigid island
#

make a new euler and pass its own euler y as value ?

barren patio
#

i've tried that and for some reason it decides to get wonky like it you changed the w axis in a quaternion

rigid island
#

hmm can you show what you tried

#

ideally you dont want to mess with eulerAngles directly

#

you want eulerangles to quaternion

barren patio
#

i've deleted basically all the rotation code i'm left with just this

#

var qerot = Quaternion.FromToRotation(TMP.transform.up, info.normal).eulerAngles;
var rot = new Vector3(qerot.x,qerot.y,qerot.z);

#

i don't know how to use the discord code thing to format sorry

#

ideally i'd like to chang rot.y to whatever id like

rigid island
#

!code

tawny elkBOT
dense rock
#

Does this make any sense?

pickups.OrderBy(x => Vector2.SqrMagnitude(x.transform.position - transform.position));
rigid island
#

careful with LINQ methods and how often you use that

dense rock
#

okay

rigid island
#

I dont recall if Vector2.SqrMagnitude is better than v2.Distance or not

dense rock
#

yes I think so

#

thats why I used that

barren patio
# 
var qerot = Quaternion.FromToRotation(TMP.transform.up, info.normal).eulerAngles;
                    var rot = new Vector3(qerot.x,qerot.y,qerot.z);
somber nacelle
#

sqrMagnitude doesn't square root the result like Distance does so it is a bit better

rigid island
#

ahh ok

dense rock
#

How should I order them in the update method?

#

should I run a sorting algorithm?

rigid island
#

You could try it maybe running it betwen specific seconds instead of every frame , might improve some bit

#

in terms of sorting yes you need some compare method

dense rock
#

how about I check how many are overlapping, and only if that changes I check/update the list?

somber nacelle
#

do you need to sort them, or do you only need access to whichever is closest?

dense rock
#

only the closest

barren patio
# 
var qerot = (Quaternion.FromToRotation(TMP.transform.up, info.normal) * TMP.transform.rotation).eulerAngles;
                    var rot = new Vector3(qerot.x,qerot.y,qerot.z);```
somber nacelle
dense rock
#

ohhh right

barren patio
#

i just want rot y to be whatever i want like placing a fan and still being able to modify rot y without it doing its own weird thing

rigid island
#

i'd have to test it

#

my head implodes with rotations sometimes

barren patio
#

ill try it, i think ive done something very similar

barren patio
rigid island
barren patio
#

do you mind vc?

rigid island

can't

#

record vid

barren patio
#

with your solution (idk if i butchered the implementation) it does this

image.png
#

perfect

#

on walls perfect until

image.png
#

you rotate and it does it on the global y

rigid island
#

oh Vector3.up is global

#

transform.up for local

#

if thats what you mean. I can't tell that much wha is going on vs whats supposed to look like

barren patio
#

i cant screen record but it when its transform.up it spins around like crazy

rigid island
#

what are you trying to do with this script exactly

#

like what is the mechanic here

barren patio
#

rotate along the local y axis

barren patio
#

trying to have this part be placable anywhere and it faces up with the normal but i want to rotate along the local y axis aswell but it just doesnt want to

#

eh ill just preprocess every variable and with what i finish ill then apply that to the transform

rigid island
#

raycast?

barren patio
#

yes

rigid island
#

so the knob is supposed to always be at the top on each normal of the cube?

#

or world up

barren patio
#

like how in a camera controller you can face any direction without the z axis

#

i figured something out thanks for helping

rigid island
#

raycast hitting itself?

swift falcon
#

if i want to find target direction its current position - target position right?

rigid island
swift falcon
#

aw thanks

barren patio
#

unity is doing a unity

#

i really dont know how to fix this

#

i rotate the y axis in inspector

#

cool it turns left and right

#

i turn the z axis in inspector

#

COOL IT TURNS LEFT AND RIGHT

#

i turn x axis it rolls forwards and back

#

lemme record this on my phone i cant make this up

why is this happening

not world

Which is the transforms up? I don't see the transform gizmo in the video

the little knob is a indicator sorry for not showing

So when you disable the script, it works?

barren patio

is there a way to vc?

lean sail
# barren patio is there a way to vc?

not in this server. though really, if you have a script which is affecting the rotation then maybe you should point that out instead of just saying the z axis isnt working.
If you need help with specific code then you should just ask about that, and look at the #854851968446365696 on how to ask

Anyone here has experience with ML Agents? Doing an enviroment where an agent needs to click a button, after the press of the button a platform with food on top will spawn. Agent needs to jump to the platform and collect the food. He learns quite quickly how to press the button but can't for anything I tried to jump to the platform. Can anyone help me? Tried multiple types of observations, using ray sensors, mixing both, nothing works. He spams jump on the edge of the innitial platform and doesn't jump to the desired platfom.

ah i scrolled up further, it seemed like the question started from the video. Though what do you mean you want to align to a surface normal and rotate around transform.up? Like which part of the object should align with the normal?
rotating it from inspector definitely will not follow this rule, and your code will constantly be fighting to set it based on this code.

barren patio
#

me head am hurt

barren patio
#

the funny remote is rotated to face the up of the surface (left of it), i want to rotate the romote around while keeping it attached to the surface

#

the surface can be facing any way so i want to rotate it regardless if the up vectors direction but follow along it

#

this is it with this code to direction it

#

Quaternion normRot = Quaternion.FromToRotation(TMP.transform.up, info.normal);

#

this is it with the same thing but using world uo vector

#

Quaternion normRot = Quaternion.FromToRotation(Vector3.up, info.normal);

#

been trying to find a fix for the last 3 hours

# 
if (Input.GetKeyDown(KeyCode.R))
                    {
                        rotation += 45;
                    }
                    //
                    
                    TMP.transform.position = info.point;
                    TMP.transform.Translate(-PlacingPart.PivotPoint.localPosition);
                                    //
                    Quaternion normRot = Quaternion.FromToRotation(Vector3.up, info.normal);
     
                    Vector3 rot = normRot.eulerAngles;
                    rot.y = rotation;
                    //
                    TMP.transform.eulerAngles = rot;
#

this is the code

#

the position part works perfectly fine, its the rotation that doesnt want to behave

info being a raycast variable

i want it to rotate on the transform up without it glitching around

It would also help if you don't record your screen from your phone but use a dedicated software for screen recording. It's really hard to look at...

Make it easier for people to help you and you'll get better/more help

barren patio
#

eh it didnt work ima give up, sorry for bothering you

latent latch
#

you seem to have a raycast/normal problem in your video so I would fix that first

barren patio
#

how so?

latent latch
#

your cursor is bringing the mesh into the other meshes before rotation

barren patio
#

thats the offset i apply to the "ghost" object

#

its meant to offset

latent latch
#

assuming you're not childing the object or anything, it seems you just need to use world up axis and rotate it on the y

#

so start debugging values and make sure your cursor isn't interfering with it

lean sail
#

i wanna have a debug screen where I can keep track of how many poco objects exist, just to make sure they're actually getting destroyed at some point. Is this a good usecase for WeakReference? Ive never really used it before and this was something I saw popup online a bit when researching.
Im thinking of something like this https://gdl.space/jilujumuno.cs

Otherwise im just trying to use the memory profiler or the finalizer to check if my instances are being destroyed, which isnt fun

one of the most important things you'll probably need to do is to ensure you mark the materials as dirty when you modify them (i assume, i'm not actually 100% sure if that would be necessary but it usually is when modifying assets via editor tools)

Otherwise you have a 3rd axis that is never used anyway

#

Because a 2d game also uses 3d objects. It's just all flat. Here it does actually occupy a third axis but that doesn't mean you need to apply this to the colliders

Its so odd to apply a 2d collider to a 3d object but here goes.

Like getting over it, I need the collision to be really accurate to what you see.

You just need to make sure the collider remains the correct orientation

Hey. Does anyone have any ideas on simplifying this Coroutine ? The methods used are irrelevant.

leaden ice

chilly surge
#

Presumably delay and interval are not the same.

gray mural
#

And that's the reason

leaden ice
#

Also instead of:

    while (true)
    {
        if (!CanMove(value))
            yield break;```
why not just:
```cs
    while (CanMove(value))```
gray mural
#

Now it should be the finished version

#

Thank you!

#

I just felt like I was missing something.

chilly surge
#

I mean you could do something like:

WaitForSeconds interval = null;

while (CanMove(value))
{
    Move(value);

    yield return interval ?? new WaitForSeconds(_moveDelay);
    interval ??= new(_moveInterval);
}

The code is shorter, but is it better? I'm not sure.

gray mural
#

Also the first WaitForSeconds after the ?? can be simplified too

leaden ice
#

well you do lose the GC optimization

gray mural
leaden ice
#

If your goal is "fewest number of lines" it's good

chilly surge
#

Wdym by GC optimization?

#

This version should only allocate 2 waits, just like the original.

Reuse of this:

WaitForSeconds intervalWFS = new(_moveInterval);```
#

oh

#

you're right

#

sorry it's early

chilly surge
#

Sounds like coffee time 😄

#

But yeah if you didn't need to care about allocations, eg if you are using UniTask, it'd be so much simpler to write and understand:

var hasDelayed = false;

while (CanMove(value))
{
    Move(value);

    await UniTask.Delay(hasDelayed ? _moveInterval : _moveDelay);
    hasDelayed = true;
}

I have a code that sends some text to my "custom arduino controller" over serial and my arduino replies to that with 2 lines of text but somehow I can only get unity to interact with one of the lines of code (even if I disable the first line it won't interact with that second line) so I feel like it has something to do with the formatting. How can I get it to also interact with the second line?

It only replies "DitIsEenTest" while I'd also expect "Goedemorgen" (The arduino does send both)

Already simplified both codes as far as I can to exclude other errors, but I'm still a modeller and not a programmer 😅

are you able to print Serial.println(receivedText)

#

make sure "TEST" is what is actually being received

drowsy aurora
#

Not sure how I would do that, can only connect to the arduino with 1 program over serial so if I'm connected with unity I can't connect to it with other software afaik.

plucky inlet
#

just print your receivedText instead of the if statement

drowsy aurora
#

oh that was already in it that was correct

plucky inlet
#

can you print if receivedText equals "TEST"?

#

oh wait, the println is on arduino site.

rigid island
#

yes the aurdino code , i was saying if they can print on display what is actually being received instead of generic logs

drowsy aurora
#

changed it to display what is being received and it is "TEST"

sorry been a long day and thought I changed it back to that before asking the question 😅

knotty sun

try

if (receivedText.subString(0,4) == "TEST")

also very unsure how the loop is actually looping

For me it looks like you are always writing two lines in one serial write.

Thats why you always get the same result in the first line?

I'm sure this should be an easy math question, but I've been fighting this for hours and can't figure it out; tried googling and AI too.

How can I find out the inverse lerp of Vector2? That is:

IF:

// A is normalized
// B is normalized
// A and B are NOT colinear
Vector2 N = Vector2.Lerp(A, B, pct)

And we have A, B, and pct, we need to implement method ?
float pct = InverseLerp2(A, B, N);

To clarify, I don't need the exact pct that was used - but rather any PCT. The following should be true

N == Vector2.Lerp(A, B, InverseLerp2(A, B, N)) // assume an equal is done using floating point estimation/threshold, not an exact equal

i am trying to make a top down shooter and I want my enemies to spawn randomly, problem is that the enemies can spawn right next to the player and damage him instantly, is there s simple way to fix this?

get the player position and the possible spawn point. Calculate the distance between these and if dist < min radius, doesn't spawn

I need some advice setting up an if for my idle animations
It's set up currently so it can only activate while player is grounded and is not moving but issue with that setup is that if the player is only moving left to right or forward to backward there's a few seconds where the conditions are all met and plays the idle for a few frames between changing run directions when it shouldn't.
I tried solving this by making a coroutine which stores the current value of the player's inputs and then waits a few seconds to see if both variables still equal each other but then that leads to the issue of the run animation taking longer to end than it should.
Any recommendations/suggestions on something better I could try to fix it?

I get a random pos from the left side of my screen to the right for X and up and down for Y, and then I instantiate the enemy somewhere inbetween

I'm sure this should be an easy math question, but I've been fighting this for hours and can't figure it out; tried googling and AI too.

How can I find out the inverse lerp of Vector2? That is:

IF:

// A is normalized
// B is normalized
// A and B are NOT colinear
Vector2 N = Vector2.Lerp(A, B, pct)

And we have A, B, and pct, we need to implement method ?
float pct = InverseLerp2(A, B, N);

To clarify, I don't need the exact pct that was used - but rather any PCT. The following should be true

N == Vector2.Lerp(A, B, InverseLerp2(A, B, N)) // assume an equal is done using floating point estimation/threshold, not an exact equal

if you need the gameobject as input, return null if failed and if you method is null, retry again. If you don't need the gameObj as out, just out a bool.

Take the transform + new Vector... ) and put it in a new vector3 before the instantiate

#

then take instantiate and put inside the if

#

make your Spawn as bool Spawn

#

retrun true inside the if and add else retrun false

#

in you Update loop, reset the timer only if Spawn == true ' if(Spawn()) '

Hello, I am currently attempting to make a procedural voxel terrain in unity and using the async and await keywords to multithread the process, except I get a MissingReferenceException after I stop playing the game in the editor for some reason. Any ideas as to why it would be the case?

Here's the code and the line I get the exception at is commented below.

private async void GenerateMeshForChunk(int i, int j, float[,] noiseMap)
{
    var result = await Task.Run(() =>
    {
        MeshData meshData = new MeshData();

        for (int y = 0; y < chunk_height; y++)
        {
            for (int z = 0; z < chunk_size; z++)
            {
                for (int x = 0; x < chunk_size; x++)
                {
                    //Debug.Log(new Vector3Int(x + i * chunk_size, y, z + j * chunk_size));
                    List<Vector3> faceVertices = GetCubeVisibleFaces(new Vector3Int(x, y, z), new Vector3Int(i * chunk_size, 0, j * chunk_size), ref noiseMap);

                    for (int k = 0; k < faceVertices.Count; k++)
                    {
                        meshData.vertices.Add(faceVertices[k]);
                    }

                }
            }
        }

        for (int k = 0; k < meshData.vertices.Count; k++)
        {
            meshData.indices.Add(k);
        }

        return meshData;
    });

    chunks[i * num_chunks + j].transform.position = new Vector3((i * chunk_size), 0.0f, (j * chunk_size)); //I GET THE ERROR ON THIS LINE!

    chunkFilters[i * num_chunks + j].mesh.Clear();
 
    chunkFilters[i * num_chunks + j].mesh.vertices = result.vertices.ToArray();
    chunkFilters[i * num_chunks + j].mesh.triangles = result.indices.ToArray();

    chunkFilters[i * num_chunks + j].mesh.RecalculateNormals();

I have my own question: I have a 2D texture like this one. What would be the best way to find the middle of the biggest area?

#

Doesn't need to be with Texture2D, I have the same data in a float matrix

misty vapor
#

I think you can do some version of heuristic matching. Perhaps fill the white pixels with two values, distance from black and number of whites surrounding the pixel.

#

or just smudge or blur the texture, the whitest area in the end is the winner?

blurring should work as long as the kernel size is right but now the problem becomes how to get the correct kernel size

I have a player, snake, which consists of the blocks, which all have a BoxCollider2D on them. The snake's length can be changed, which means it can have a large amount of blocks. Moving a snake around translates the 1st block on 1 unit to the desired direction, and the other blocks' positions are assigned to their previous one. Every block is 1x1 in Unity coordinates, and its position should always stay inted at the end of the "continuous" movement.
What would be the best way to apply the gravity to the snake to not decrease the performance too much? Using the Rigidbody2D with the CompositeCollider2D doesn't work as desired, as the collisions with the ground blocks aren't calculated precisely and the blocks' positions aren't inted after the application of the gravity.

leaden ice
#

unless you're doing some physics-based twist on it

gray mural
# leaden ice I would probably not be using physics for a Snake game at all

Right, that's what I thought too. I wanted to use a while to create a loop for every single block and check whether it has a ground block 1, 2, 3 etc. units under it. It works perfectly when the distance between the ground and the number of blocks aren't too big, but once they get, the performance is going to decrease significantly.

#

Perhaps, there is any efficient method, which allows to check for the nearest Collider2D under the CompositeCollider2D.

#

But it's also so that the distance between the snake's block and the ground block should be considered.

#

Even when the 2nd block is under the 10th block, the smallest distance between the block and the ground block should be chosen

gray mural
#

It's also important to break the process when the Collider at the distance 1 is found, as this is when the snake is staying on the ground

#

And every block's collider should cover the entire 1x1 space

Why can I not cast an object type as a int to a function that takes a int param? Why do I need to first cast it to a float?

public void SomeNetworkFunc(object[] data)
{
SomeLocalFunc((int)((float)data[1])); //works without issues at runtime
//instead of simply...
SomeLocalFunc((int)data[1])); //causes "cast is not valid" at runtime
}

public void SomeLocalFunc(int value) { ... }

If its an object, shouldnt I be able to cast data to a int? Even as a float, shouldnt data be able to be cast to an int without the double-cast? Is there maybe a better way I could handle this to not need the double cast? (nothing wrong performance wise in my game with it and its not called very often on the network, I just think it looks ugly and seems like a extra step forced on by my approach maybe)

knotty sun
# 
        object[] data = new object[10];
        int i = 0;
        int? x = data[i] as int?;
#

the reason you can do object -> float is that float has NAN for invalid values int does not have that

#

so using int? will get around that

soft shard

Ah interesting, thanks for explaining that, I dont think ive ever used ? on a variable type, ill try it out

basically it makes value types nullable

I like for this. bool? - true, false, maybe

true, false, file not found

hey guys! quick question. what would be the most efficient method of spawning objects in a procedural terrain generator?

I saw something about how structs don't get collected properly in the editor and so when playing in the editor the struct's data won't "reset" until the scene is fully reloaded. Is that true or am I mixing it up with another thingg

leaden ice
#

Or what that has to do with structs

tall scroll
#

idk I just glimpsed at the convo but something about how if you change the data in play mode it will stay like that even when you stop playing, which isn't the usual behaviour. I may be confusing it with scriptableobjects though I'm really not sure

sonic holly

You'd have to be comparing it with something to make a statement like that

mm, got it. so Instantiating with static batching is an effective way to spawn things?

oh, unless you include new GameObject(), of course

If you're willing to step outside GameObjects you can do other things

i imagine that pooling would be more performant than that. i haven't really done much testing with that myself but i did make an audio source pool that basically does that.

so im confused by trying to combine two loops

i have a level preview that is supposed to populate each button with one level. all it does is change the sprite and the text for now.

but i cannot get it to work. it always takes the last entry of the levels (in this case level 3).

what should happen is ofc, that the first button is level 1, the second button level 2 and so on.

here is the code thats driving me nuts:

     //runs through each buttons
     foreach (var button in buttonImageText)
     {
         //checks if sprite was overwritten
         if(button.Key.overrideSprite == true){return;}

         button.Value.text = "Empty";
         //runns through each level
         foreach (var level in levelSpriteList)
         {                                           
             //SHOULD: checks if the button sprite is equal to a level sprite
             if(button.Key.name != level.name)
             {
                 button.Key.overrideSprite = level;
                 Debug.Log("amount of sprite calls");
             }
             else
             { button.Key.overrideSprite = null;}

             //SHOULD: checks if button text already has level name
             if (button.Value.text == level.name) { return; }

             if (button.Value.text != level.name)
             {
                 button.Value.text = level.name;

Can Vector2.normalized ever return 0,0?

knotty sun

no because if normalized it must have a magnitude of 1

I believe it returns a zero-vector if you give it a zero-vector

indeed

knotty sun

being pedantic, it's not 'returning 0,0 it's returning an invalid input

it explicitly returns a zero vector if the input is too small to normalize

i am not sure if that includes very very short vectors, or if it only includes the zero vector

Async is great, it's just that Unity never used it so there's not many places where it's available

UNREALTED to my previous message:

Question: I'm using render Textures to create my impostors. Is it the right way or it's wrong ? Just to be sure before I do every angle (Sphere).

#

Don't need to say to add Fade between angles. I will.

what's an imposter

#

oh is that some sprites with different frames

#

id' just use the sprite/texture atlas

From a article: An Impostor

Impostors is a technique used for a background of the game environment to fake 3D objects by using its texture maps and transfer them onto images or billboards.

This way, the number of polygons is much fewer which leads to spending less time to render a scene but the quality of the environment remains almost the same. The key point of this technique is to replace those 3D objects that aren’t in the main focus of the player’s view so he won’t spot the difference.

#

To sum up, It's a way to fake a 3D gameobject with a 2D sprite. The cherry tree on the far right is 3D. The two in middle are 2D.

no clue the overhead of using multiple cameras like that even if you're just capturing a single render, so something to profile. Otherwise cache yourself the textures and stick em in some dict with texture coordinates imo

hi im trying to learn how to have items in my enviroment with scriptable objects attached to store the items data. i have got the scriptable object file working but struggling to add the data to a game object that my player can pick up. anyone able to direct me to some resources that can explain how to do this.

ok so done that but its not loading the prefab for the item into the scene. im guessing im missing something else

#

i have loaded it onto a empty object. should i be adding it to a prefab of the game object even though the SO has a gameobject field?

#

what im trying to do is have items that can be picked up and scrapped so i am trying to use SO to hold the data on the materials for the item

knotty sun
#

you should have some thing like
Project
SO Script
-- SO Asset
MB Script
-- Field of same type as SO script
Hierarchy
GameObject
-- Instance of MB script
-- Reference to SO Asset

yea dont have anything like that i have a prefabs folder for the stuff i made in blender to learn this stuff and a scripts folder for the SO and other scripts

#

what does MB stand for ?

knotty sun
#

Monobehaviour

nimble cloud
#

ok

knotty sun
#

The GameObject can also be a prefab in the project

nimble cloud
#

right but in my SO i have set a public GameOject field to set the prefab to but the prefab is not being displayed on the empty game object

knotty sun
#

you are going to have to show your inspectors of the objects

nimble cloud
#

am i right in thinking i just need to setup the object with the SO then make a prefab of that game object in the Hierarchy to add multiple of the same item with the SO

knotty sun
#

if I understand you correctly, yes

nimble cloud
#

ah ok so thats good then

Would you guys recommend me to switch from dotween to leantween

Was hoping to get some help with getting UI elements that display what planet is what in the solar system of my game. Currently I managed to get these elements to orbit but they are not alligning themselves at the center of my camera.

i thought having the prefab in the SO would mean that i had to just add the script to a empty game object and it would display the object listed

knotty sun
#

what script?

nimble cloud
#

ok its working thanks for the help @knotty sun

i want to limit the movement of a recttransform to not overflow below the screen at all. so if i detect overflow, i just change the pivot to (0, 0), and the anchorMin to (0, 0) and the anchorMax to (0, 0), and position the anchoredPosition.y to 0. works well. but then i want to set the pivot / anchors back to their original values (0, 1) for pivot, and (0, 1) for anchors, but it messes up the positioning. even if i remember the localPosition before setting back the anchors and set it to that after changing them. any ideas why?

in the last line, i accidently set the world pos, but even setting the localPosition still has the same issue

Hi, I was wondering where do I go for help, as I'm trying to create a death floor, which works but it appears im clipping through objects on spawn

-Attempted elevating the characters/player
-Considered setting the movement speed to 0 but not sure how to call to another file/class
-changed the distance to reach the death floor

Using Scripts to create the deathfloor/checkpoint based system
