do you need transform?

rigid island
jolly dune
#

ok do you know what the issue is this is really bizarre

rigid island
#

try also printing the end result like movementVelocity

jolly dune
#

that works as intended except no z value

somber nacelle
#

you are using Vector2 rather than Vector3

jolly dune
#

yikes

rigid island
#

oof how i missed that too

#

unity just turns the v3 into a v2 and 0s the z 🥲

jolly dune
#

yea

#

now I need to clamp the values which is gonna be a pain

rigid island
#

V3clampmagnitude

jolly dune
#

well no I have to make it stay inside a placing area

rigid island
#

thats even easier

jolly dune
#

I'm making a 3D version of the watermelon games except instead of fruit it's gonna be my classmates faces

jolly dune
#

yea but I don't know how to properly acsess the transform values

my favorite thing is going "well that didn't fing work" after every fail because it lessens the pain with a laugh

Hoping this is a good place to ask this, but is it possible to add a white tint to a sprite? Kind of like how you can tint a sprite with the unity sprite renderer, but since the rgb values there are by deafult at 255, and also capped at this, I can't make the sprite anymore "white". Not looking for a full solid white, just a tint.

rigid island
#

like what a flashing effect?

Which approach would you use to draw these arrows dynamically at runtime? (ie. in the example, they represent physics forces and animate on FixedUpdate())

maybe a line renderer but that prob wouldn't explain the arrows at the tips

Hi, I'm facing a very weird issue. I have no idea how to fix it.

#

[DELETED]
↑ this is a dumb script I wrote

#

Whenever I add it to a normal (empty) GameObject in the scene, then, as soon as I try playing from the editor, my object becomes permanently infected with a RectTransform thereafter, replacing its regular Transform component.

#

this then stays that way when I stop playing and get back to the Editor (I believe one warning appeared when entering Play Mode, the other one when exiting~)

#

Why does that happen and how can I prevent a RectTransform replacing my Transform, for objects equipped with this script?

#

Using version 2021.3.9, by the way!

#

Do not hesitate to ping me if you've got any clues ^^

#

Also, googling did not help me much, I only encountered the one person seemingly using a Mask, or whatever UI thing it was, in their script, thus tricking Unity into believe that this object was meant for a UI canvas. If that's the case here… I can't see it? Where would the problematic object be in there?

jade bison
#

aaaand now the issue just won't happen again -_-

#

fixed I guess! ^w^
but yeah weird, no idea what causes it

Can someone help me with my unity 2d project? I cannot seem to make it that whenever the sprite goes left and right they start the walking animation.

anim.SetBool(). Sets a bool condition on the animator to whatever value you put in as the second parameter.
'myRb.velicity.magnitude' is the "length" of your velocity, i.e. 0 when there is no movement and higher than 0 when there is. Basically how fast it is going. by writing
(myRb.velocity.magnitude > 1) we create a bool that is true when the magnitude value is greater than 1 and false if it is lower.
So the code is: Set the bool condition on this animator named "isRunning" to true if the RB has some velocity, and to false if it doesn't.

Got a question about a dont destroy on load gameobject

So currently I have this scene that has a UI button gameobject that has an OnClick function tied to enother gameobject. The problem is that that other gameobject has the Dont DestroyOnLoad and if there is a duplicate itll destroy the copy, this means that the UI button's OnClick function wont work cuz the other gameobject is missing. How do I reassign the other gameobject to the ui function?

I'll be honest, you shouldn't be connecting ui elements to a ddol object/singleton. You should be thinking of another object oriented way to go about what you are doing.

But if you must do what you want, you need to attach a script to your button and set a static class reference to it so it's easily accessible, Instead of using game object find. Regardless of how you end up finding the button again, you just need to call remove all listeners on the button and then add the on click listener to point back to your function.

open charm
#

Im still new with how OOP works

hexed pecan
vagrant agate
#

In short, "most" ddol's are used as managers/singletons for utility classes, persistence session game state, etc. Or when the ddol object script relies on itself or its children only. It shouldn't have relation to any objects not within itself when moving scenes so it doesn't lose references.

I'm not saying you can't do what your doing and it be fine.

open charm
#

whats ddol again?

maiden quail
open charm
#

oh right ok

#

So what ur saying is that ddol objects must be independent from any other element aside from their own children?

and i just inherit it to all my interactable classes

gray raft
somber tapir
# maiden junco I wanted to add a few parameters to each interactable, but I don't think that it...

You could have a class called 'InteractableData' and pass that as parameter. Then you can either add variables to it or inherit it and create specific data for each interactable, i.e. DoorData. The only problem with that is that you need to cast it to the correct type before you can use it.
But there should never be a reason to get the gameObject in the first place, since NPCScript has a reference to it anyway.

It does an awful job of explaining how to start a custom package and what it looks like to develop one.

For the custom package manifest it doesn't tell you what its supposed to look like; one has to grok 3 pages of documentation to know what it is supposed to be. Even then, there are so many questions you have to read in between the lines for.

It's laughably bad.

how should I go about clamping the Z rotation of my object between e.g. -40 and 40 degrees

#

this just makes it permanentally stuck at -40

somber tapir
hoary pewter
#

oooh right

somber tapir
#

You might have to subtract 180, then clamp, then add 180 back

#

there are probably also functions that handle exactly that, but I don't know them

how to get reference to loaded scene other than OnSceneLoaded and GetSceneByName/Index/Path ?

# 
           AsyncOperation asyncLoad = SceneManager.LoadSceneAsync("Scene2");
            while (!asyncLoad.isDone)
            {
                yield return null;
            }
            asyncLoad.

can i get reference to scene from asyncLoad ?

#

i load multiple scenes with the same name so GetSceneBYName doesnt work.

@polar marten you need to make sure you read and understand messages before you attempt to "answer" to ensure you aren't hallucinating

yes

I have all these rooms generated on Start via procedural generation, is there a way i could bake occlussion stuff post generation?

or would i need to come up with my own occlusion solution for htat?

maiden junco
#

This image describes perfectly its behavior

hard viper
#

how does this work when writing the interface then?

plucky cobalt
#

ok i have a better idea.

maiden junco
# hard viper how does this work when writing the interface then?

Lets pretend that you have:

class Fruit {}

class Banana : Fruit {}

interface ICovariantSkinned<out T> {}

interface ISkinned<T> {}

and the functions

class Program
{
  void Peel(ISkinned<Fruit> skinned) { }

  void Peel(ICovariantSkinned<Fruit> skinned) { }
}

The function that accepts ICovariantSkinned<Fruit> will be able to accept ICovariantSkinned<Fruit> or ICovariantSkinned<Banana> because ICovariantSkinned<T> is a covariant interface and Banana is a type of Fruit,

the function that accepts ISkinned<Fruit> will only be able to accept ISkinned<Fruit>.

hard viper
#

where is Peel defined

#

because this just looks to me like two overloads

maiden junco
#

i updated the example

plucky cobalt
#

i have a box trigger and i want it to whenever a player goes inside it, the door opens i made a bit of code to find out the problems with it and to make it work.

if ("Gorilla Rig") is inside of ("OpenTrigger") play anim ("DoorOpen") wait until ("DoorOpen") is finished then play ("DoorIdle)

again this is just simple code that i want to make work, how do i fix it?

maiden junco
plucky cobalt
#

sure

#

i sec

hard viper
#

i see. so how do I populate the interface differently when it is a Covariant interface?

#

the whole point of having the generic is to call methods depending on the type, after all

maiden junco
#

but if you gotta assign the same interface that is of type of a class A to a type B you gotta put the out keyword in front of the generic

plucky cobalt
maiden junco
# 

class A {}
class B : A{}

interface IMyInterface<out T> {}

IMyInterface<A> foo;
IMyInterface<B> = A; // This will compile since the generic its defined as out T

class A {}
class B : A{}

interface IMyInterface<T> {}

IMyInterface<A> foo;
IMyInterface<B> = A; // Compilation error
maiden junco
plucky cobalt
#

yeahj

somber tapir
# plucky cobalt yeahj

There are hundreds of tutorials on how to get started, I suggest you check them out first to learn the basics of C#

maiden junco
#

for checking trigger states of a gameobject you can use methods like OnTriggerEnter, OnTriggerExit and OnTriggerStay

#

for playing animations you could use an Animator and define some states on an animator layer (the base layer by default)

plucky cobalt
#

should i don what this says?

# hard viper so... how do I put a member into the interface to actually make use of the <out ... 
public class Enemy { }
public class Boss : Enemy { }

public interface IEnemyProvider<out T>
{
    T SpawnEnemy();
}

public class EnemySpawner : IEnemyProvider<Enemy>
{
    public Enemy SpawnEnemy()
    {
        // Implementation to spawn a regular enemy
        return new Enemy();
    }
}

public class BossSpawner : IEnemyProvider<Boss>
{
    public Boss SpawnEnemy()
    {
        // Implementation to spawn a boss enemy
        return new Boss();
    }
}

And the implementation:

IEnemyProvider<Enemy> regularEnemyProvider = new EnemySpawner();
Enemy regularEnemy = regularEnemyProvider.SpawnEnemy();

IEnemyProvider<Boss> bossEnemyProvider = new BossSpawner();
Boss bossEnemy = bossEnemyProvider.SpawnEnemy();
hard viper
#

that helps. ty

#

and just to be clear, then you can't use T as the type of an input arg? because there's no way to know?

latent latch
#

I use convariance just because the compiler yells at me and I have to comply with it

hard viper
#

on that topic, is there a non-dumb way to do this:

    if (associatedPrefab.TryGetComponent(out ISimpleAutoTileMono<TilePlacementInstance> mono)) mono.AssertValid();
    else Debug.LogError(error_msg");
} else {
    if (associatedPrefab.TryGetComponent(out ISimpleAutoTileMono<TilePlacementContiguous> mono)) mono.AssertValid();
    else Debug.LogError(error_msg");
}```
#

where public interface ISimpleAutoTileMono<TTilePlacement> where TTilePlacement : ITilePlacement

#

I was wondering if I could make it simpler with Covariance, but that interface requires a method where the input is of type TTilePlacement

maiden junco
#

you could create a method that checks whether its Individual or not

# 

void CheckAndAssertValid<T>() where T : class
{
    if (associatedPrefab.TryGetComponent(out ISimpleAutoTileMono<T> mono))
    {
        mono.AssertValid();
    }
    else
    {
        Debug.LogError("error_msg");
    }
}
#

and then

if (autoObjConversion == AutoTileToObjectType.Individual)
{
    CheckAndAssertValid<TilePlacementInstance>();
}
else
{
    CheckAndAssertValid<TilePlacementContiguous>();
}
maiden junco
#

like int, float, bool and so on

hard viper
#

I think that would work. Just checking options to avoid all the downcasting.

#

but I don't think it would work here, which is unfortunate.

humble void
#

So, there seems to be very little documentation about the new navigation package that's why I am asking around: I want to bake a navmesh on runtime but it takes a ridiculous ammount of time and it blocks my main thread, is there any way to move it to another thread? Can it be used with the jobs system? Can it be run asynchronously?

maiden junco
hard viper
#

one more interface question. I want an interface to only be attached to Monobehaviours, and I need everything that implements that interface to call the exact same method in OnDestroy. Is there a way for me to do this?

humble void
heady iris
latent latch
#

Probably want to use events for that, otherwise do it all in the base class

hard viper
#

I am thinking about how to do this.

#

maybe the interface should force the implementation of a property tied to an event, and then interface method can add something to it?

heady iris
#

One option would be to make your own class that subclasses MonoBehaviour

#

Give it virtual OnDestroy and Awake methods

hard viper
#

or maybe interface forces public void OnDestroy, and then interface can add a method to it?

heady iris
#

Have the class test if it's an instance of IWhatever and do the needed thing if it is

#

This feels gross

#

well, only a little gross

# 
protected virtual OnDestroy() {
  if (this is IWhatever interfaceInstance) {
    interfaceInstance.Cleanup();
  }
}
latent latch
#

that's not too bad

#

I do something similar cause I can't be bothered sometimes

heady iris
#

now you just need to make sure you call the base method if you override the virtual method

hard viper
#

It is a generic interface, so it can't be put on a gameobject normally

#

must be made concrete

#

changing to a monobehaviour doesn't change that

heady iris
#

ah, I'm not sure what you could do, then

#

maybe reflection

hard viper
#

idk. maybe is there any way for an interface to force a class that implements it to call specific code?

hoary pewter
# 
public void PlayerRot(float rotDirection)
{
        Quaternion targetRot = Quaternion.Euler(0f, transform.rotation.eulerAngles.y + rotSpeed * rotDirection, 0f);

        transform.rotation = Quaternion.Slerp(Quaternion.Euler(0f, transform.rotation.eulerAngles.y, -transform.rotation.eulerAngles.y), targetRot, rotSpeed * Time.fixedDeltaTime);
        isRotating = true;

        timer = 2;
        StartCoroutine(ResetRotationFlag());
  
    }
#

anyone got any idea as to whats causing the rotation to continue where it left off before resetting to 0?

hard viper
# heady iris maybe reflection

Possible workaround:


public class DestroyDetector : MonoBehaviour {
    public event Action DoOnDestroy;
    public void OnDestroy() => DoOnDestroy?.Invoke();
}
///// <summary>Remove self from entity ledger. </summary>
private void LogDestroyedObj() => EntityLedger.GetInstance()?.LogDestroyedEntity(gameObject, EntityLedgerCategory.Tile);```
#

too dumb?

#

feels wasteful to make a whole monobehaviour like this

hexed pecan
hard viper
#

I believe I am as far as unity allows

hexed pecan
#

Maybe a default OnDestroy method in the interface?
Havent used those myself, just throwing some ideas

hard viper
#

I'm not exactly sure how unity works with that tbh

#

I might make it an abstract generic class, but I feel like that might restrict my ability to make classes, since we can only inherit once

#

fuck it. I'll just make an abstract class

lean sail
#

I might be remembering wrong but the default interface methods would probably just cause your regular OnDestroy methods to not run at all. I say abstract class is exactly what you want here

hard viper
#

I'm just going to go with my standard pattern:
public abstract class SimpleAutoTileMono<TTilePlacement> : SimpleAutoTileMono where TTilePlacement : ITilePlacement {}
public abstract class SimpleAutoTileMono : MonoBehaviour {}

#

the latter class just being a convenient way to access the non-generic methods

heavy forge
#

I have a box that I want to move to my variable called mousePos (mouse position but kept within distance from the player). Using transform.position = mousePos works well except that it doesn't take in account other colliders. So I'm trying to use RigidBody2D.MovePosition(mousePos) but for some reason the box only moves on the y axis and not on the x... I have no idea why this isn't working as transform.position = mousePos does work and I'm not changing any code (except for the line where I move the box ofcourse) when I'm using MovePosition instead. Is this a common issue? Is there a better way to take in account other objects?

lean sail
heavy forge
#

What other way is there to do this then?

lean sail
# heavy forge What other way is there to do this then?

depends on what this is really for, either use non-kinematic rigidbody with addForce/velocity or move the transform but use physics casts to make sure nothing is in the way.
In your current setup, did you debug what mousePos is? I assume something was colliding with your object which is why it couldnt move on the X axis

heavy forge
#

mousePos is what I want it to be, a Vector2 "clamped" in a circle around the player. Nothing is colliding with the object, it just refuses to move on the x when using MovePosition. I'm assuming that isn't the way to do it then, but I'm also not sure if using velocities is a good idea. Because I want my object to just be at the mousePos rather than going there if that makes sense.

I'll try it out tomorrow

Hey guys, I have noticed unity does not seem to execute the Awake function in abstract classes - But I am pretty sure it used to do that in older versions.
I have an abstract class that handles some backbone of my management stuff and I need the awake method to be executed.

Do I need to find a workaround and if so what could that look like?

ionic adder
plush basin
#

Because what I have is an abstract class Manager containing a static reference to itself

public abstract class Manager : MonoBehaviour
{
    public static Manager Instance;

    private void Awake()
    {
        if (Instance != null)
        {
            throw new ArgumentException();
        }
        Instance = this;
    }
#

And in my thinking declaring this static instance of the manager would then force it to initialize the script, because now we have a static Manager that can be accessed from everywhere. But this Awake method is never called

latent latch
#

awake should be called

lean sail
latent latch
#

Oh, it's abstract so yeah you need to derive an actual class you can create an instance of

plush basin
#

But I'd really like to have this static Instance field so that anywhere in the project I can go

Manager.Instance.DoMagic();

Because then the actual management stuff can go in regular MonoBehaviours that sit somewhere in the scene. The Manager.Instance just handles handing out references to scripts that need them. This way I dont have to hardwire all the references or have all the management classes be static. But I see the error in my thinking now and will retry something else.

#

Ahhhh I am such a dud 🤣
Ofc, I am always only thinking on the code level and keep forgetting sometimes that theres a whole engine around my code. Thanks!

plush basin
#

But now I kinda wanna know how it would be done ngl

latent latch
#

Consider looking up a service locator pattern (basically just another abstraction layer for your singletons which allows for the implementation of a subscription/observer model) as this sounds like something you're trying to develop

Can I have a Tilemap Collider change Scene when colliding with player, but the scene is specific with the Door using SceneManager.LoadScene(). Town door would be a difference scene, Guild door would be a different scene, etc.

You need to put some logic on the collider that defines what scene to go to and which spawn point in tihat scene to use.

You have to move SendToHouseScene out of that function, to the class scope

also, use nameof(SendToHouseScene) to avoid explicit strings

then you can just go to whatever scene the door says to go to

seems like a simple scalable solution

You can set the scene in the inspector for the door.

#

This is my layout of the map. The doors are highlighted, and are the ones I need to fix. They are all contained in one Tilemap called, "Door". I need each door to teleport to a different scene.

Or - have a map of tile coordinate to scene name somewhere

#

and look up the scene name based on the door coordinate

#

seems like a lot of maintenance though

Is there not a simpler and efficient solution outside of those two?

imo, i would not use tilemap brush for anything but testing

if you want to make custon levels with tilemaps, you should use Tiled. If you just want to use tilemaps to represent things programatically, you don’t need a brush either

hey
in Unity is there a interface system (maybe its not the same name as UE) ?
Like you have a "asset" or script that contains a list of functions with inputs and outputs, you can then add it to any object in game
then from another game object, you can check if this interface exist and call the functions, but no errors occurs if the function doesnt exist in given game object

tell me if i wasnt clear

note: after writing this message, it feels like a "interface" in Unity would just be a c# script

cosmic rain
#

Sounds like it.

#

Unity events might help you reference methods in the inspector

how would this part work but no errors occurs if the function doesnt exist in given game object ?

Hey. Not sure if this is the right channel to ask and it's probably a dumb question, but yeah.
I was wondering why the second " and ) have a lower opacity than the first? (I'm using Visual Studio 2019). Reason I'm asking is because I know that, when I use brackets where not needed or "this.", etc., they get like that too. But not sure why they do here tho.

You have (-1, 0) twice in the list of valid movements

thanks for letting me know

#

i was also wondering if there is a way to reduce the if else statements in the row column check function

mellow sigil

For one you don't need a special case for column and row 0. The second for loop just won't run in that case anyway.

#

same for column/row 7 actually

steady moat
# modern magnet i was also wondering if there is a way to reduce the if else statements in the r...

You could also merge the concept of checking row and diagonal in a single for loop.

List<(int dx, int dy) straights = new List<(int x, int y)>() {(1,0),(-1,0)(0,1),(0,-1)}
List<(int dx, int dy) diagonals = new List<(int x, int y)>() {(1,1),(-1,1)(-1,1),(-1,-1)}

foreach((int dx, int dy) direction in straights) 
{
  for(int i = 1; i < 8; ++i)
  {
      (int x, int y) position = (currentX + direction.dx * i, currentY + direction.dy *i);
      if(IsValid(position))
        AddToValidPosition(position);
      else
        break;
  }
}
modern magnet
#

where does the diagonals list come into play??

modern magnet
mellow sigil
#

Presumably you added those special cases because you don't want the second (or first) loop to run on those columns/rows, right? Well they don't run anyway on them so they're just unnecessary

steady moat
# modern magnet where does the diagonals list come into play?? 
List<(int dx, int dy) straights = new List<(int x, int y)>() {(1,0),(-1,0)(0,1),(0,-1)}

For loops check the condition before the first loop and just do nothing if the condition is already false

hard viper
#

that notation works?

#

shit I’ve been using the tuple class, which is so confusing to understand later

modern magnet
#

the pieces that are not on the edge require both sides to be checked thus i did this

mellow sigil
#

Right but the "normal" case already skips the other direction there

#

so there's no point in making a special case

hard viper
#

so if you have a 5x5 board, I make a 9x9 array or something, that automatically offsets itself when you access

#

then you don’t need to check edge cases, which are obnoxious

modern magnet
hard viper
#

you just need to check for null, which you would do anyway

#

idk if this helps for your case

modern magnet
hard viper
#

i have a lot of systems in my game that are on a grid, and I really don’t want to constantly deal with edge cases. a padded matrix helps me keep my code much simpler

#

modern magnet
#

no, i meant why not use i++?

hard viper
#

++i is the awkward cousin of i++

steady moat
#

In other words, I'm doing it so I don't have to hear that from other team member

modern magnet
#

but doesn't using ++i cause the loop to offset by 1?

steady moat
modern magnet
#

or am i wrong

hard viper
#

i don’t think so

modern magnet
#

ooh

hard viper
#

++i is just awkward when people use the ++ in the middle of a line where other things are happenning for some reason.

steady moat
#

It is like if you did:
some instruction;
++i;
some instruction;

maiden junco
# 
int a = 5
Debug.Log(i++) // OUTPUT: 5

int a = 5
Debug.Log(++i) // OUTPUT: 6
fervent furnace
#

++i is faster than i++ a bit since no temporality register is needed to store the value before increment
the compiler will optimize it

hard viper
#

so effectively no difference unless you call it in the middle of a line

#

with other things going on, as above

#

in which case what it does is actually just different

fervent furnace
#

it is true for almost all cases unless you start to use pointer....

I left that life behind. I never want to see another pointer ever again

Tile question. I have a design for a tile that requires corners in terms of rule tiling. By symmetry, I have a little border that I could express with ~12 tiles (with different rotation/mirror symmetry). And a design inside that can’t be rotated, but can be expressed with maybe 9 tiles tops? If i have no symmetry, this would be like making 256 tiles, which is way too much.
Q: Is there a way to make a tile that displays like two tiles overlaid on each other?

  • If i create an enumerator object once, can i re-use it to start multiple coroutines? Will they work when started simultaneously?
hard viper
#

one instance? i don’t think so

#

Ienumerators do things by calling:
while (enum.MoveNext()) yield return enum.Current

#

if you have one enumerator, every MoveNext() call will advance it

#

unless start coroutine makes a copy? but it’s a reference type, so i don’t imagine so

cold egret
#
  • That's what i assumed. So if i ensure that one enumerator is only ever used once, i can reuse them by invoking reset on them first?
leaden ice
leaden ice
#

What you can do is save a reference to the coroutine function itself in a delegate, and call that repeatedly

#

E.g. cs Func<IEnumerator> example = MyCoroutine; StartCoroutine(example()); StartCoroutine(example()); StartCoroutine(example());

cold egret
#
  • Which will still create new enumerator objects per call, but also cause extra overhead for delegate objects storage. The problem is garbage allocation in the project that relies on coroutines heavily, not the access to the methods
hard viper
leaden ice
#

There is no way to avoid allocation with coroutines

#

If you want to avoid allocation, do not use coroutines

cold egret
#
  • I see. Unfortunate, but the only way to go ig. Thank you
hard viper
#

as far as I understand, the main coroutine garbage is the new WaitUntil etc instances

leaden ice
#

The enumerator itself and the Coroutine object are also allocated

heady iris
#

executing a method that returns an enumerator creates garbage

#

because an instance of a compiler-generated class has to be created

hard viper
#

aren’t both those two objects super light tho?

leaden ice
#

They are light but if your goal is zero allocation they aren't zero

hard viper
#

drop in the bucket imo

#

unless you spam them, everywhere. which has its own host of issues

#

but that becomes an architecture issue, not an allocation issue

cold egret
#
  • Even drops in a bucket eventually will fill it. Besides, the project i've been asked to optimize throws not drops and not even spoons but other buckets
cold egret
hard viper
#

coroutines are not where I would start optimizing

#

corotuines would be more a target to straighten things out

#

what I mean is that the use of coroutines isn’t going to be what crushes performance. it’s probably what they are doing

cold egret
hard viper
#

god damn wtf bro

cold egret
#
  • Ikr
hard viper
#

why do you have so many coroutines

#

i have one class that might be helpful

cold egret
hard viper
#

this is a very helpful class that helps me cut down on coroutines

#

it's a singleton with an extremely late early execution order. A lot of coroutines exist because you just want to execute one line on the following frame.

#

in those cases, I just subscribe a function to one of the delegates of this singleton

cold egret
#
  • Events also create garbage fyi. Sometimes less than coroutines, but it's not guaranteed
hard viper
#

they should be mostly like function pointers

#

it makes a bigger difference if you have a coroutine with a while....yield return new WaitForFixedUpdate(); loop

#

because that shit makes garbo every fixed frame.

#

and it's a bit simpler to set something to execute just once with this pattern

#

given your case is a doozy, it is one option that might help

latent latch
#

events making garbage is pretty surprising to me

#

i need to cut down of mine later on because of it

cold egret
#
  • The smallest single target delegate contains at least function and instance pointers, then you get parameters and local variables in the instances of the generated classes that they might point to additionaly to your type. Besides, delegates are immutable and will always reallocate when you add/remove something
hard viper
#

I think he's refererring to the garbo that comes from actually calling delegate Combine

#

maybe this is worth benchmark testing.

latent latch
#

im thinking of making my own event system and just deal with pointers myself

hard viper
#

if you need to really optimize, maybe making a List<Action> might be useful. Then a singleton holds a block of memory that stays allocated

#

List<Action>, then .Add, .Clear, .GetEnumerator....

#

instead of +=, =null, ?.Invoke()

#

again, just lighter. people rarely make coroutines for the fuck of it. it's almost always because there is some timing aspect that needs to be respected.

cold egret
cold egret
latent latch
#

the benefit of coroutines is sleeping them and getting somewhat accurate wakeup times

#

otherwise I'd just do it all in a single updateloop and poll them

#

so runtime performance vs some garbage

#

which equates to performance too, but effectively polling hundreds through update is probably the worse of two.

modern magnet
#

modern magnet
# polar marten why do you have `else { break; }`

if a tile is occupied by a piece, suppose a white piece, in that case, i do not have to check further since i can only highlight till that point thus using break to immediately break out of the loop

polar marten
#

maybe start by correctly enumerating a tile's adjacent tiles

then you can break the loop after the first if block

latent latch

make use of break; and continue; in your loops

modern magnet
latent latch

isn't that what you want

if you had multiple loops, one inside another, break; will break out of the current loop.

But since this is the only loop then you break; out of this and continue on with your code

i dont, in the case that are iterations left where the tiles wherein the checks are left to be made for the white pieces

nope actually that wont work i guess

can always create flags beforehand if you need some for inside of the forloop

or inside if you need them for the current iteration

You could use quaternions and unity would automatically rotate it the shortest way

I have the transform's forwards, and a direction which is (target - enemy).normalized. And I must rotate the first one into the second one, by rotating the enemies in the Y axis

Also, I just tested benchmarking a giant delegate with 100k += operations on it. It is extremely slow, and that scales as n^2. Replacing it with a list implementation makes it way faster. Adding a function to the delegate becomes totally free. And removing a function from delegate is still much faster. The time to fully += 100k, then -= 100k was 10x faster with list implementation

Hi. Im currently trying to code a Volleyball game in unity. I have done basic movement and also the field setup, (its 2d) but what I dont manage is that I want the player to have to press specific button-combos in order to perform specific volleyball moves. So in this example, I want the player to first click "Q" and then choose one of WASD to choose what side hes gonna set the ball to. This is my code:

private void Setting()
{
    if (Input.GetKeyDown(KeyCode.Q) && Ball.transform.position.y > transform.position.y && Ball.transform.position.y < transform.position.y + 1)
    {
        rb.isKinematic = true;

        if (Input.GetKeyDown(KeyCode.W) && !Input.GetKeyDown(KeyCode.D))
        {
            ballrb.AddForce(transform.up * 30);
            StartCoroutine(Wait());
            rb.isKinematic = false;
        }
        else if (Input.GetKeyDown(KeyCode.D))
        {
            ballrb.AddForce(transform.right * 30);
            StartCoroutine(Wait());
            rb.isKinematic = false;
        }
        else if (Input.GetKeyDown(KeyCode.W) && Input.GetKeyDown(KeyCode.D))
        {
            ballrb.AddForce(transform.right * 20);
            ballrb.AddForce(transform.up * 20);
            StartCoroutine(Wait());
            rb.isKinematic = false;
        }
    }
}

Right now its the raw version without any timing tries, I didnt manage so I kept it like this. Could someone tell me how to modify it in order to make the player be able to have a little time window (say 1 second) to press the next button?

Thanks!

if you are projecting onto a trivial plane (like x-y plane), then the projection is trivially (x,y,0)

# open charm How do I get a random coordinate from a navmesh

https://docs.unity3d.com/ScriptReference/AI.NavMesh.SamplePosition.html a random point inside https://docs.unity3d.com/ScriptReference/AI.NavMeshData-sourceBounds.html
this will have biases. there is no general way to select a random point on a navmesh (inside a navmesh) in exactly 1 call that gives uniform likelihood for each point. you can repeatedly sample for small distances until there is a hit for a uniform likelihood, but that may be unexpectedly slow. usually you want enemies to spawn on poisson disks and not uniform random (see image https://repository-images.githubusercontent.com/274968879/4de75d00-c818-11ea-90d9-ba023a3bbe64) this will have a bigger impact on game feel then better random selection

rigid island
#

Ah navmesh data has the bounds, I was looking on NavMesh class

polar marten
#

this will have biases. there is no general way to select a random point on a navmesh (inside a navmesh) in exactly 1 call that gives uniform likelihood for each point

rigid island
#

also depends how far/random it needs to be..

Eg my enemies generally spawn closer to player point so a nice Random.insideUnitsphere works with SamplePosition

#

How would I calculate a % from 0% to 100% based on the input that gets increasingly bigger?
Something like a Tween probably.

For example experience required formula that goes from 10 to 1000, but from level 1 to 10 the total is 100, but 10 to 11 already requires 50 etc. Up to max level of 20(19 to 20 would require like 300xp)

#

What do I need to achieve something similar?
I think Tween might do the trick, but I am not sure.

#

So the total exp from 1 to 20 = 1000, but lower levels require less experience.

rigid island
#

probably a curve

#

or animation curve

upper pilot
#

yeah, what do I need to make it happen?

I found something called Weighted Random, so I probably need Weighted not random 😄

no I need like a math behind it

latent latch

just use this

upper pilot
#

I am searching for weighted but everything I get is for random numbers lol

#

I'd prefer something I can control myself, dont want to add assets from outside.
I did that once before based on someone recommendation and I regretted it later 😄

#

Also its for random numbers with predefined %, I need something that works with different amount of items.

latent latch
#

actually reading what you're asking I dont think a weighted random would be applicable here

#

what's wrong with a curve again?

upper pilot
#

I don't know what curve to look for

#

Is it a good idea to use animation curve for non animation code?

rigid island
rigid island
upper pilot
#

well there has to be a formula for that curve right?

rigid island
#

why do you need the formula..

upper pilot
#

I thought the video you posted was for animating the progress bar.

latent latch
#

you're just looking to formulate your own experience gain. Usually games do stuff like an exponential curve of some values but it's up to your design

upper pilot
#

ok let me explain it a bit better

rigid island
upper pilot
#

I want to set max exp number, like 10000
This is how much exp you need to reach max level.
max level can be anything, but lets say its 100.

If you go from level 1 to 2, it will use like 0.5%(50) of the 10000
from 99 to 100 it will be like 10%(1000)

somber tapir
# upper pilot I thought the video you posted was for animating the progress bar.

you can do a ticket type system. Every item gets a certain amount of tickets, you put all the tickets in a pot and draw one. Whichever item the ticket belongs to is selected. The more tickets you give an item the higher the chance for it to be selected and you can easily add more items without having to readjust all the values.

upper pilot
rigid island
#

animation curve name is misleading but its just a curve(actually yes sampler is better term because you can make other shape not just curve) .

latent latch
#

your curve would be exp per level

rigid island
#

same thing as typing it manually with as you say, a formula..

fervent furnace

animation curve is a sampler

#

just an function(t)

Ok quickly coming back to you, i advanced a lot and now Im at the part of serving the ball, that one is supposed to be with a real combo of buttons, not like the other one where I pressed "Q" to prepare and then the button in the direction I want it. You said to make a class with a combo list, but I have no clue what that would look like since I just came from 1 year of working on python projects, could you quickly get me in?

rigid island
#

but i assume that was its original usecase ?

#

not sure what unity's thought is there

latent latch

if you want exacts then you should just formulate your own function

}```
This keeps track of any inputs that match one of the combos. 
You can assign the inputCodes in the inspector. It might be better to make that a ScriptableObject for easier editing.
It would probably be better to keep a list of all valid Combos, i.e. if the player pressed Q only check Combos that start with Q and discard the rest until we reset.

InputCombo is a class that holds a KeyCode list for the combo, i.e. 'Q-W-W' and a Vector2 which will be the force applied to the ball.
ComboChecker has a list of all InputCombos the player can do and a List of KeyCodes that keeps track of which keys have been pressed so far.

is there a decent workaround to not being able to make static virtual/abstract methods?

#

I have a base class with a static method, where it wants to call a static method, which depends on which class it derives from.

#

....static virtual/abstract isn't allowed. And I would need an instance to call a non-static method

well you still haven't shown the Boost method where you're actually acting on that input, but i'd bet you're not doing anything like checking what the phase of the action is. realistically you don't even need that interaction on your input action and can just react to the canceled phase

But you could just Slerp or RotateTowards from current transform.forward to aimDirection, no?

let's say I have one component where I need to do a LOT of TryGetComponent calls. Would it be a good idea to speed it up by adding:

public static IReadOnlyDictionary Directory => dict;
private void Awake() { dict[gameObject] = this; }
private void OnDestroy() {dict.Remove(gameObject);}```
Good idea? bad idea?
quartz folio
hard viper
#

that’s my first thought, but it seems like unity would ensure this won’t leak? Given I do need to to a huge amount of TryGetComponent calls for just this one component, what would you recommend?

#

by huge, I am trying to get rid of several thousands of these calls per frame

#

i’m also not a big fan of dumping a ton of memory onto the heap

orchid gust
hard viper
#

maybe I should do a similar thing, but on a singleton holding the dictionary?

quartz folio
#

so unless you're careful you will hold onto those objects in memory for the lifetime of the program

hard viper
#

i’m mostly at the mercy of OnDestroy, which is always kind of wacky

loud wharf
#

And it's not just cause you're using output as the input for lerp.

orchid gust
#

Your right I just switch to Slerp, it doesnt look like it makes an immediate difference but Im sure its my testing enviorment

loud wharf
#

.
I guess, try to imagine a box, and imagine another rod in the middle of the box.
Then imagine the rod rotates. The rate of change depends on the contact point in the rod and the parameters of the square.

#

I'm not sure if I can get the analogy correct. :p

orchid gust
#

yeah, if u get to the corners its gonna change the speed

#

I cant quite explain how to fix the issue i was having so I hope the code can explain itself

loud wharf
#

The right way would have been to get the angle of the aimDirection and the currentDirection and lerp the angles then convert back.

#

In the SetAimDirectionFast, looks like you just set the currentDirection to the aimDirection but did some extra steps converting it into degrees then back into vector.

Anyone have problem with jittery movement when timescale is decreased for slowmo? Like everything else is smooth slow mo but the physics stuff moves obviously in large steps.

I've doing movement on fixedupdate and use FixedDeltaTime. Rigidbodies are kinematic and I set their transform position on FixedUpdate. Enabling interpolation does not help.

leaden ice

Rigidbody interpolation only works when you're moving via the Rigidbody

#

You are bypassing the physics engine

Either use the physics engine to move (with interpolation on) or move in Update

Is it widely known that unity2D-collision detection for an individual object stops working if you ever directly set transform.position(but directly setting rigidbody2d.position)works perfectly fine, no matter the type of rigidbody)?

I think I understand why it happens(rb pos and trans.pos are not reading the same value and might differ due to simulation and interpolation concerns), but the fact that it seems to break permanently for as long as the object in question is loaded and is never mentioned in any of the documentation has me wondering

in unity 2D, on a what is the intended best practice solution for doing collisions in a game or system that does not intend to use simulated physics(Outside potentially collisions through the physics system)?

cosmic rain
#

If you really want to rebel, you could use physics queries, but imho that's an ugly solution. Might hit the performance as well.

tiny stirrup
#

I guess my intutition is that if you want say basic AABB-collisions in unity, you use boxcollider

knotty sun
#

if you are using physics in any shape or form then you use rigidbodies, if you do not you use transforms

tiny stirrup
#

In unity 3d that is not always true though, there are many situations where as far as I understand it directly setting transform.position even on a simulated object is the 'correct' solution

#

and it certainly never breaks the collisions

#

not to shit on unity2D

cosmic rain
knotty sun
#

setting the transform will always break physics

tiny stirrup
#

Break them in the sense that they have to resimulate, yes

#

but not break as in they are now-non functional

cosmic rain
#

No. There's no "resimulation". It breaks different things like collision, interpolation, etc..

cosmic rain
knotty sun
#

it breaks them in the sense that the situation is indeterminate

tiny stirrup
#

youre probably right or were just saying the same thing

#

All Im really trying to ask is: Say I have two squares, and I want unity2D to give me some sort of message or hookable event when they overlap, without having to write custom AABB collisions or whatever, what is the best practice/intended way to do this

#

?=

knotty sun

physics triggers

tiny stirrup

for reference, this guy is specifically trying to optimize his game because like 10% of all computation time is spent on coroutine and related stuff

    {
        switch (slimeType)
        {
            case SlimeV2.SlimeType.Normal:
                return NormalSprites;
            case SlimeV2.SlimeType.Fire:
                return FireSprites;
            case SlimeV2.SlimeType.Water:
                return WaterSprites;
            default:
                Debug.LogError("Unknown slime type: " + slimeType);
                return normalSprites; // Default to normal sprites
        }
    }```

Anyone know how I could automate this process for all my slimeType enums?

as i have a bunch of slimeTypes:

    {
        Normal,
        Fire,
        Water,
        Alien,
        Cat,
        Cyclops,
        Kraken,
        Leaf,
        Shark,
    }```
#

I am probably going to opt to manually add them in everytime i decide to add a new type

that would not solve the issue, or perhaps I misunderstood the question (last post by op)

Coroutines are class objects so they have their small GC overhead too

#

And doing new WaitForX instead of caching it will also produce garbage

fossil goblet

#

The compiler might turn the switch statement into a dictionary anyway

#

At least that used to be the case with something like 8+ items

#

Dont worry about switch performance, is what Im trying to say

fossil goblet
#

Awesome 🙂

hexed pecan
#

So do what is best organized for you

fossil goblet
#

It's been fun trying to make my game more optimal, ive tried to use more managers that target all my slimes instead of having massive bloat of scripts on each slime

dusk apex
#

If you ever get more than 50, consider populating a list from the inspector and access using enum as int or whatnot.

#

Else a switch is fine for a manageable dataset - relative to size.

i can get around ~200 and it seems runs fairly well on mobile surprisingly

no animations yet tho

It's just a lot of copying and pasting. Editing can also be a nightmare that can potentially break stuff

Hey all. I am trying out the new input system and i made a little Vector2 setup with WASD. Im using ctx to store my values in a Vector2, and am moving my player accordingly. Only problem is, once i press a value it never resets to 0,0 when nothing is pressed. Anyone know why?

leaden ice
#

yep

#

you're only subscribing to performed

#

the zeroing out bit happens in cancelled

lavish frigate
#

ahh

leaden ice
#

honestly for every frame movement it's a lot simpler not to use events

#

just use update

lavish frigate
#

if movement.canceled += ctx => movementInput = Vector2.zero?

#

something like that

leaden ice
# 
void Update() {
  movementInput = input.CharacterControls.Movement.ReadValue<Vector2>();
}``` that's my recommendation
lavish frigate
#

also, i can normalize my Vector2 either in action or in binding, which is correct practice?

leaden ice
#

there is no correct practice, it depends on your needs

lavish frigate
#

Normalizing in action feels right then, movement works now by the way so thanks again

Hey y'all. I've here with a question on optimizing my rhythm game.

Would it be a good idea to pool notes here? I will never be able to anticipate the amount of notes in a map, so I'm unsure if pooling a large amount of gameObjects will work, especially if there is a section of map with an extensive density of notes. I just want to support pooling with maps with just under 10,000 notes (mappers have insane difficulty barriers), and note densities up to 30nps (notes per second)

I currently use Instantiate, but I typically don't find much overhead however I would like to be careful for later.

somber tapir
fervent furnace
#

the node should disappear after player presses it or time out?
return it to pool and reuse the note gameobject

#

I love when Unity puts this in their example scripts..

What is not performant

#

I haven't really checked, what kinda overhead does changing material properties have

rigid island
# 
void UpdateMaterial()
{
    switch (m_Server.currentIngredientType.Value)
    {
        case IngredientType.Blue:
            m_ColorMesh.material = m_BlueMaterial;
            break;
        case IngredientType.Red:
            m_ColorMesh.material = m_RedMaterial;
            break;
        case IngredientType.Purple:
            m_ColorMesh.material = m_PurpleMaterial;
            break;
    }
}```
#

not sure why they don't just use an event 🤔

rigid island
hexed pecan
#

I think it's not performant because instead of sharedMaterial it uses material which instantiates a new material IIRC

rigid island
#

just odd doing it every frame when it can just be when m_Server.currentIngredientType.Value changed

#

they literally have an event for that xD

#

wish they wrote in comment why they did it that way..just laziness or wat..

eager steppe
fervent furnace
#

the pool should grow dynamically if you need more objects

AssetDatabase.onImportPackageItemsCompleted

I use this callback when execute AssetDatabase.ImportPackage(package, false);

everything works well for simple packages, but when I tried to import the FacebookSDK or Firebase package, for some reason this event simply does not get called... Can someone tell me why this is happening?

Hey there, I wanted to ask if it is possible to draw a prefab or something using either gizmos or similar techniques, i need to preview some motion that needs to be accurate displaying a referenced gameobject

#

I have tried instantiating during gizmos but I do not know if it's possible to know when an object has been deselected in order for the prefab to disappear and prevent clones, and keeping the hierarchy clean

Good evening everyone

Auto-importing packages from code

I ran into a small problem that is a little annoying

This means I import packages through code like this

AssetDatabase.ImportPackage(package, false);

Unity has the following events

AssetDatabase.onImportPackageItemsCompleted += OnImportPackageItemsCompleted;

AssetDatabase.importPackageStarted += name => Debug.Log($"importPackageStarted : {name}");

AssetDatabase.importPackageCancelled += name => Debug.Log($"importPackageCancelled : {name}");

AssetDatabase.importPackageCompleted += name => Debug.Log($"importPackageCompleted : {name}");

AssetDatabase.importPackageFailed += (name, message) => Debug.Log($"importPackageFailed : name: {name} message : {message}");

The crux of the problem is this

If I import some simple packages with several files, then everything works as expected for callbacks, they are called as in the screenshot (screen 1)

But if I take some package from Facebook or Firebase, then the callbacks are like this, and the Complete callback is not called at all (screen 2)

Does anyone have an idea why this could be?

but well if there's no other choice i'll do that

if you want to visualize in the scene view

#

And then draw the child meshes with their localPosition and localRotation

#

Might be more complex if your children are nested

#

In any case set the matrix and then draw them with positions/rotations/scales relative to the parent

Hey all! Just wanted to ask a quick question in here -- i'm currently working with Editor scripting in Unity for the first time and working on making a better effects system for my game.

The way it works is you can add multiple effects to the list of abstract EffectAction classes. You can add actions like camera shake, playing audio, spawning a particle, etc. For every effect I want to add, I have to add the effect into an enum and use a switch to add the coressponding effect to the list --- which is fine right now but I feel it may get tedious as I continue to add effects. Is there a better way of doing this?

Here's the editor code:

#if UNITY_EDITOR
[CustomEditor(typeof(EffectEvent))]
[CanEditMultipleObjects]
public class EffectEventEditor : Editor
{
    public Events eventSelected;
    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();

        EditorGUILayout.LabelField("Actions:");
        eventSelected = (Events)EditorGUILayout.EnumPopup(eventSelected);

        string buttonName = $"Create Action";
        if (GUILayout.Button(buttonName))
        {
            switch(eventSelected)
            {
                case Events.CameraShake:
                    (serializedObject.targetObject as EffectEvent).AddAction(new CameraShakeAction());
                    break;
                case Events.PlayAudio:
                    (serializedObject.targetObject as EffectEvent).AddAction(new PlayAudioAction());
                    break;
            }
        }
    }

    public enum Events
    {
        CameraShake,
        PlayAudio,
        SpawnParticle
    }
}
#endif```

Any idea if there is any way that the clients that are not hosts of a lobby receive callbacks from LobbyEventCallbacks ?
at the moment only the host receives them

(using the lobby service)

// THIS IS ONLY CALLED ONCE AT THE START OF THE SCRIPT

LobbyEventCallbacks _callbacks = new LobbyEventCallbacks();
ILobbyEvents _lobbyEvents;

private async void SubscribeToCalls()
    {
        //SUBSCRIBE TO CALL
        _callbacks.LobbyChanged += Callbacks_LobbyChanged;

        try
        {
            _lobbyEvents = await Lobbies.Instance.SubscribeToLobbyEventsAsync(curLobby.Id, _callbacks);
        }
        catch (LobbyServiceException e)
        {
            Debug.Log(e);
        }
    }
    private void Callbacks_LobbyChanged(ILobbyChanges changes)
    {
        Debug.Log("Lobby Changed");
        //ONLY THE HOST RECEIVES THIS MESSAGE
    }
}

I have a problem with managing my code, I'm making a system where you pick up a object, the placement trigger is activated and when you drop the object in it it activates another object and it destroys those two. Now I'm wondering how i could do this to multiple object and multiple placement triggers in 1 script or maybe if you have another solution i would be happy if you said it. Here are the scripts:

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

public class PickUpScript : MonoBehaviour
{
    [SerializeField] private LayerMask PickupMask;
    [SerializeField] private Camera PlayerCam;
    [SerializeField] private Transform PickupTarget;
    [Space]
    [SerializeField] private float PickupRange;
    private Rigidbody CurrentObject;
    private bool isHoldingObject = false;
    public GameObject Placement;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.E))
        {
            if (isHoldingObject)
            {
                DropObject();
            }
            else
            {
                TryPickUpObject();
                Placement.SetActive(true);

            }
        }
    }

    void TryPickUpObject()
    {
        if (CurrentObject == null)
        {
            Ray CameraRay = PlayerCam.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f));
            if (Physics.Raycast(CameraRay, out RaycastHit HitInfo, PickupRange, PickupMask))
            {
                CurrentObject = HitInfo.rigidbody;
                if (CurrentObject != null)
                {
                    CurrentObject.useGravity = false;
                    isHoldingObject = true;
                    CurrentObject.isKinematic = true; // Prevent physics from affecting the object
                    CurrentObject.transform.SetParent(PickupTarget); // Set object's parent to the PickupTarget
                    CurrentObject.transform.localPosition = Vector3.zero; // Set local position to center within the target
                    CurrentObject.transform.localRotation = Quaternion.identity; // Reset local rotation
                }
            }
        }
    }
#

I removed the drop logic because it was irrelevant and i couldnt send the message

# 
using UnityEngine;

public class PlacementTrigger : MonoBehaviour
{
    public GameObject objectToActivate; // Assign the GameObject to activate in the Inspector

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Item"))
        {
            // Activate the assigned object
            if (objectToActivate != null)
            {
                objectToActivate.SetActive(true);
            }

            // Destroy the collided item and the trigger
            Destroy(other.gameObject);
            Destroy(gameObject);
        }
    }
}
#

I would gladly hear what you have to say

fervent furnace
#

i think you need array

#

or queue, though i suggest using array since it is serializable in inspector
when you pick up an object, it needs to search for the corresponding collider to activate
when the collider is triggered, it needs to activate next object

#

then overlapXXX should work for checking if the drop position is inside the triggered collider

sharp bison
#

I get the idea but im not going to lie im not very experienced with coding, i understand most of the code but i cant really code a lot myself (i used chatgpt for the code lol), i didnt want to post this in the beginner code channel since this is pretty advanced i think

#

how do you even get that smart

#

ive actually been using unity for like 3 years and i havent learned a lot of coding

#

i guess im going to research what you said to me, thanks for the help

pure garden
#

You have an object that you place in a trigger and when that trigger detects collision you set an object to active?

sharp bison
#

because all of them will be masked under item and tagged item

pure garden
#

oh ok yh understood

sharp bison
pure garden
#

Just add a variable to placement trigger of type gameobject and check if other.gameobject is equal to desired object

#

ig?

sharp bison
sharp bison
pure garden
#

Do a List of gameobjects and check if the List contains other.gameobject

sharp bison
#

Okay let me make an example

#

Theres a ornament on the floor

#

i pick it up

#

the placement trigger object activates
