[tepid river]

you mean if you freeze the update thread with a yield return new WaitForEndOfFrame?

you only suspend your IEnumerator, not the whole update thread

[velvet quartz]

How can i do for do the whole update thread ?

[tepid river]

you dont and you dont want to

it would freeze the whole game

[velvet quartz]

ok sad.

[tepid river]

if you want to stop your object from running code every update call, put a bool and if(myBool) return;

[velvet quartz]

So how can i stop the update for no go further

[dim spindle]

You dont

Why do you want to

[tepid river]

just return early.

[velvet quartz]

I want when i disable nav mesh agent obstacle for my AI because i need to wait the next frame for mesh update.

[dim spindle]

That works depending on context yeah

[velvet quartz]

i can't return becuse the code is on function called from update.

not on update himself

[tepid river]

while(true) {
;
}
will suspend your update thread 🤡

[dim spindle]

Just return a bool that tells if you should return or not, somethinf like that

[tepid river]

yeah the way to go is to only run your function if you really want to.
and not to start suspending things

[velvet quartz]

Here is my script i need to stop the update loop when i disable the nav mesh agent obstacle for wait the next frame.
https://github.com/pytchoun/UnityCodeReview/blob/main/Scripts/AI/ZombieController.cs

[earnest gazelle]

Yes, I mentioned as well. It is vague. Instantiate using CreateInstance or all instantiation (using developers through CreateInstance + in loading scenes by unity)

[thin aurora]

No, Coroutines run in the "background" and the delay will have no impact. That said, are you sure you want to invoke your coroutine in Update? It will invoke each frame.

[thin aurora]

You add a boolean "isRunning" and return; the Update method at the start when it's true. Set it to true and the Update will not invoke anything in it.

[thin aurora]

Considering you already have a guard clause in the Update method it should not be hard to make another check for the navmesh agent. I see there is a class-scoped variable you disable so you can check that.

Unless it's not your code? 🤔

[velvet quartz]

guard clause ?

class-scoped variable ?

[severe marsh]

if condition and class field

[thin aurora]

You already have a check in there using return;, and you have a variable in your class you can check

Seems pretty simple to add another check.

[velvet quartz]

Yea return if dead.

[velvet quartz]

which variable ?

[thin aurora]

The navmesh agent you disable.

[viscid briar]

Hey does anyone know how to encode a string into a bytes array?

[rustic ember]

First result on google: https://www.c-sharpcorner.com/article/c-sharp-string-to-byte-array/

using System.Text.Encoding

[viscid briar]

thanks. Sorry I should have included that I need a method for encoding function calls and their parameters within smart contracts

[rustic ember]

I'm not exactly sure what that means

[viscid briar]

Yes it's probably too specific but I'm attempting to supply a multicall function on the ethereum blockchain with bytes array data

[rustic ember]

Sounds interesting. I'm not sure I can help tho 🤷‍♂️

[viscid briar]

fair enough, thanks anyway

[graceful egret]

Is there any way I can hook into an asset duplication event?

I want to change some serialized fields to be a different value when something is duplicated
Ideally I want to have access to the original asset as well as the new one

[modest bough]

apologies for the hissing + clicking, i need to fix my audio filters
So the player character is connected to a central point by a LineRenderer, and I'm trying to get it to wrap around obstacles, which it mostly does well. The issue is that, with small objects, it's not sticking, and is instead triggering the unwrap function. The current implementation I'm using is:

{ropePositions.RemoveAt(ropePositions.Count - 2);}```
where *ropePositions.Count -1* is the player, -2 is the most recent line connection, and -3 is the second most recent. 
So in instances like in the video, where you can raycast to both of the two most recent line segments, it removes the most recent segment. 
My previous solution involved measuring the angle between the three points, but that seems to have caused more issues, making certain points stick too well instead. So I need some way of more accurately telling the line when to come unstuck.

oh discord doesnt like mkvs. ill convert it

[soft shard]

Dont think there is a event specifically for an asset being duplicated, but there is an event for when an asset gets imported, duplicating an asset should cause an import, maybe one of the post processors is what your looking for:
https://docs.unity3d.com/ScriptReference/AssetPostprocessor.html

[graceful egret]

Thanks! Ill look into it

[hollow stone]

Are your objects gonna be able to disappear as well?

[modest bough]

ideally there'll eventually be physics puzzles and maybe some sort of consumable resources, yeah, so down the line i'll also need to figure out how to manage that, since if i pull one of the sticks out of the ground the line hangs in the air until i move around it

[hollow stone]

I would consider moving back the line path and do more casts maybe.

You would want to have some minimal size of the object you can use for delta how far back on the path you move.

Then you may find that you collide to a new object that you insert in the list instead.

[modest bough]

smaller steps does sound like it'd be useful down the line for simulating a more rope-like behaviour
my next idea was closer to pic but it doesn't feel very adaptable

[hollow stone]

You can also consider doing circle/sphere casts for narrowing it down and not having to do too many casts ( I would do this once I know that a shape has dissapeared).
So I would go for delta back as the red line in my image, and do that for each segment. If that fails to hit, possibly do some bigger sphere/circle cast to see if there are any objects blocking and then narrow it down.

[modest bough]

I'm familiar with deltaTime, but i'm not quite getting what you mean by delta back. like, a percentage of the distance between the two points?

[hollow stone]

Lets say you define your smallest radius of a shape to be size X, then you could go distance X (Half diameter) back on the line to be sure you would not miss a shape to do a cast to see if you have free vision to next point.

[modest bough]

oh i see, that makes sense

[rustic ember]

How can I pass any type of parameter in a method? Is that possible? Something like this: ```cs
public void Method(AnyType _value)
{

}```

[vagrant blade]

You'll want to look up the concept of generics

https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/types/generics

[rustic ember]

Thank you 🙏

[trim schooner]

I doubt an SO can have scene references

[knotty sun]

you can also use the type object

[plucky inlet]

SoundClips and Prefabs are not in Scene Scope while things out of your hierarchy are in scene scope. Your Scriptable Object is a dataset and therefore also not part of the scene per se

You want a generic public field for any script, did I get that right?

You cant directly serialise a generic to the inspector

You could try, as others suggested, to go with the type object or monobehaviour if they are all monos, but they have to share some base class or interface.

[modest bough]

https://hatebin.com/igsaymagee
so i've got this so far - took the distance between the last two points, normalized it, and added those two points as further checks before removing line segments, but lastPoint is still being removed as before, so i'm not sure what's gone wrong there

[rustic ember]

Thanks

[rain minnow]

Technically, you could. It'll show the weird error/missing text but it'll have the Metadata for it. Not smth to use or rely on though bc it doesn't work all the time . . .

[hollow stone]

Is your minimum radius 1?

[rustic ember]

How can I pass something as the Type?

[hollow stone]

Right now if you're Hitting anything on the ray it's removing it.

[trim schooner]

I've never tried, was just assuming it'd be the same as is for prefabs

[solemn raven]

hey, which one was it ?
if I wanted to round float to the highiest int/whole number
example.

int objs = 41;
int boxCapacity = 10; 
int boxRequired = 41/10; // this is a float "4.1", right ? ... how to make the result 5 not 4 ?

thanks !

[modest bough]

yeah the sticks are width 1, so i figured turning the direction into a unit vector and multiplying it from there as needed would fit

[rustic ember]

It's wrong

[hollow stone]

Alright, as long as you know it^^

[rustic ember]

It's ceil Mathf.Ceil()

[solemn raven]

oh yeah , i have just noticed , thanks 😄

[prime acorn]

I have a sprite property on a ScriptableObject, I use this sprite as the icon for the object when instantiating it.

Its basically a list entry which is generated like so:

public class FishListEntry : MonoBehaviour
{
    public Sprite FishImage;
    public string FishName;
    public string FishAmount;

    [SerializeField] private Image FishImageField;
    [SerializeField] private TMP_Text FishNameField;
    [SerializeField] private TMP_Text AmountField;

    private void Populate()
    {
        FishImageField.sprite = FishImage.sprite;
        FishNameField.text = FishName;
        AmountField.text = FishAmount;
    }
}```

Now when I try to set the FishImage property it says "NotSupportedException" the code for that looks like this:
```cs
FishListEntry fle = go.GetComponent<FishListEntry>();
fle.FishImage = group.FirstOrDefault().GetComponent<FishController>().fish.Image;

Where the group is a grouping of the individual controllers, and "fish" is the SO holding the information for that specific object

TL;DR:
I have a sprite as a property on an SO, I reference an instance of that SO (not the SO itself) and want the sprite of that instance to be displayed on my image component

[severe marsh]

you could use a generic method:

void Method<T>(...) {
    // T is the type
}

[solemn raven]

not correct btw >> that gave me 4 not 5

[rustic ember]

Oh. That's because you're dividing with integers

int / int = int

Do this: cs (float)myInt / myInt2

This will equal a float

That you then can Ceil

[coarse herald]

https://pastebin.com/EUD98MYs hmm... this system seems to be letting some button mashing through. canInput is set to true on every beat

[solemn raven]

u were right 😄 , but i used CeilToInt because i wanted an int

[spare dove]

I'm working on a save system for my inventory, and I need to save a list of item (scriptable object) and amounts for each inventory box. Basically I would like to make a dictionary that can take two separete variable as the value, what would be the best way to do this?

[solemn raven]

thanks ❤️

[hollow stone]

Sprite.sprite?
You're getting component of an SO? It doesn't have components does it?

[modest bough]

problem is the delta casts aren't doing anything - delta is definitely on the opposite side from the player, there shouldnt be any way for that cast to return true

[prime acorn]

Where did I say component on SO? Even if thats just nitpicking but I think I clearly stated the sprite is a property on an SO and I want the sprite property from the SO to be applied on an image component

[hollow stone]

You're leaving code out. But I assumed FishController is an SO? And you're getting it by "GetComponent<T>" ?

[prime acorn]

No, FishController is a Controller, or in other words, a Behaviour, Fish is the SO, specifically group.FirstOrDefault().GetComponent<FishController>().fish is that SO in question

[hollow stone]

Use debug drawline to see where the lines are

[hollow stone]

So Sprite is the name of your SO?

[prime acorn]

No sprite is a property on fish

fish is of type Fish

and Fish inherits from SO

[hollow stone]

Right mb.

[cobalt wave]

can we see the FishController code?
cuz at the moment I think it's the fact that Image doesn't exist in fle.FishImage = group.FirstOrDefault().GetComponent<FishController>().fish.Image;

[knotty sun]

typeof()
which in your case is
typeof(2) or typeof(int) as 2 is an int

[hollow stone]

Would assume something is breaking on "group.FirstOrDefault()" probably best to post the full error as well for better help.

[rustic ember]

I think there's been a misunderstanding. I need to access the value. The value of any type

[knotty sun]

object o
Type t = o.GetType()
?

[prime acorn]

public class FishController : MonoBehaviour
{
    public float speed = 1;
    public bool direction = true;
    public Fish fish;

    // Update is called once per frame
    void Update()
    {
        transform.position = new Vector3(transform.position.x + speed * (direction ? 1 : -1) * Time.deltaTime, transform.position.y, 0);
        gameObject.GetComponent<SpriteRenderer>().flipX = direction;
        if(!direction && transform.position.x < -8)
        {
            direction = true;
        }
        else if(direction && transform.position.x > 8)
        {
            direction = false;
        }
    }
}```

[hollow stone]

You can box it in object, but that's not really something you usually want to do as it's expensive.

[rustic ember]

What's the most performant way to recast fx. a float as an int?

[cobalt wave]

yes

[rustic ember]

Genius. Thank you 🙏 I think I know what to do

[prime acorn]

I think this is way more interesting then

[hollow stone]

SpanFish.65 is the "fle.FishImage = group.FirstOrDefault().GetComponent<FishController>().fish.Image;" line?

[cobalt wave]

interesting

[prime acorn]

SpawnFish.65, yes

[rustic ember]

The Seven Deadly Seas fishing update?

[polar marten]

okay just eyeballing this and seeing you have a library, i don't know if this tool can extrude meshes with holes. you also have to choose the right faces

it's not Maya

[modest bough]

player.position to delta 100% hits the pillar so it shouldnt be removing anything

[polar marten]

i meant of the actual game so i can get a sense for what it looks like

[hollow stone]

Can you send your code again?

[prime acorn]

Pls @ mention me in any replies, need to pick up my gf, so I wont miss them when Im back

[modest bough]

https://hatebin.com/igsaymagee
i did also try changing the linecasts to raycasts in case that made a difference but nothing seemed to change

[hollow stone]

You did not fix the boolean logic for removal I mentioned.

[cobalt wave]

I'm trying to figure it out, but at this point I think the best action is trying to create a single fish (not in a group), and then trying to change only that one fish's sprite to rule out that the error comes from groups.
Then if it's still only a scriptable object error oof I don't know why.
The only thing I would try changing for now is the Image name in the Fish : Item class because unity already has a definition for Image to maybe something like fImage (f for fish) or anything else
@prime acorn

[hollow stone]

Right now IF both linecasts are hitting the object, it WILL remove the line vertex.

[tepid jewel]

i have triangulated it and have the vertacies, but I am not sure exactly how to choose the right triangles?

[modest bough]

ah mb i getcha now, i think i might have gotten myself mixed up with raycasts
so i've set them to if (!Linecast)
Good news: fixes the snapping
Bad news: if the line touches the same shape twice in a row, it gets stuck and -i assume - can't come loose because the linecasts hit the shape they're 'stuck' to and then stop

[hollow stone]

Make sure you nudge it out of the object.

[modest bough]

hmmm... tiny OverlapSphere to find the nearest terrain object and then moving it 0.01 units away?

[hollow stone]

Many ways, but depends how you add the points right now. if you're finding the pure edges or just takes the point where you hit the ray to the object etc.

[modest bough]

just takes the point where the linecast terminated

maybe i should make it find the edges so i can physics stuff later tho

[rustic ember]

Is there an easy way to get an element of an enum by using an index? fx. cs public enum PlayerState { Idle, Walking, Falling, Crouching } In this case I want PlayerState[0] to be PlayerState.Idle, PlayerState[1] to be PlayerState.Walking, etc.

Is that a thing with enums?

Or do I need an instance of it?

[hollow stone]

So this might cause issues when you're moving fast etc. One easy way if dealing with squares and circles that are symmetric around their center is to just either have fixed offset from center or apply an offset - since it will always be pointing in the correct normal direction outwards from the edge where you hit. If you're dealing with more complex shapes you would want to find the edge in some way to either look up vertices or do multiple casts.

[polar marten]

hmm... well what is your goal

what are you trying to do

[hollow stone]

Enums are numerated from 0, you can also assign each enum value a number e.g. Idle = 3

[rustic ember]

How? cs PlayerState test = PlayerState[0];?

[hollow stone]

Simply cast it

(PlayerState)0

[rustic ember]

oh, nice. Thank you

[hollow stone]

Not even sure if you need to cast it, can probably assign directly from integer as it is it's backing type.

[dim spindle]

Why do you want to do this? @rustic ember

Just curious

[rustic ember]

Just wondering if it was possible. I don't need it tbh

[dim spindle]

Oh

Ok

[modest bough]

yeah, at one point the player was triggering new segments when they were moving too fast 😄 but yeah i definitely dont want to be going too fast regardless
i'm still only mucking about with basic shapes for now, but i'll plan for complex shapes
i'm sure there's some way to instantiate an empty game object at the point of impact as a child of the pillar or similar, then have the linerenderer track it
alternatively, i might place some premade transforms on the prefabs for my level objects and just check which one is closest to the impact - in the case of the pillar, one for each corner and middle of each vertex should be fine
i'll sleep on it for now cause it's late, but thank you very much, i greatly appreciate the help you have given me today

[idle flax]

Hey, I need help converting a number.
I have a float that ranges between 0-2. I need to convert that float to a number that ranges from 0-100, but reversed. For example, if the float was 2, I want it converted to 0. If it was 0, I want to convert it to 100. How would I do this?

[pastel holly]

I have quick question, I am trying to make an simple AI that will essentially just be state machine with 3-4 different states.
My idea of state machine is just to have switch case for each state,
But I been looking around and I see people handling their states with use of Animator, making most state transitions on animation end.
Can someone guide me to what best practice/approach would be ?
This is for a enemy that detects player, walks to them and initiates a fight like in dark souls but without complexity.

[buoyant crane]

(-100 * (yourNum*.5)) + 100

[idle flax]

Thanks, I'll try that.

[buoyant crane]

sorry for so many edits, that should be the last one 🙃

[rustic ember]

I have a script: cs public class CharacterInput : MonoBehaviour { public Vector2 moveInput; public bool jump; }
I then have two other scripts deriving from CharacterInput: cs public class PlayerInput : CharacterInput { KeyCode jumpKey; private void Update() { if (Input.GetKey(jumpKey) { jump = true; } else { jump = false; } } } and cs public class CPUInput : CharacterInput { private void Update() { // Use neural network to calculate input } }
From a third script I want to use GetComponent() ```cs
public class CharacterMovement : MonoBehaviour
{
CharacterInput inputData;

private void Start()
{
inputData = GetComponent<CharacterInput>();
}

private void Update()
{
if (inputData.jump)
{
Debug.Log("Jumped");
}
}
}```
Will GetComponent<CharacterInput>(); return whichever one of the classes PlayerInput and CPUInput it finds attached to the game object? And how can I modify a field that is local to PlayerInput from CharacterMovement?

[buoyant crane]

the .5 normalizes your number from 0 to 2, to 0 to 1. Then you figure out how much to subtract from your max amount

[idle flax]

Thank you.

[fast belfry]

Shouldn't it be something along the lines of:
(1 - x / 2) * 100
?

[tepid river]

"why the hell does my spaceship keep accelerating downwards, how did i mess up the AI"
yeah the AI just reached its target and went to idle, not zeroing out the gravity any more

[buoyant crane]

i didn’t think it could be simplified further, but you’re right 😅

[rustic ember]

Can I start a coroutine by invoking a UnityEvent?

[rustic ember]

Would (1 - x * .5) * 100 be faster? Is multiplying by .5 faster than dividing by 2?

[tepid river]

yes multiplication in general is faster than division, but if its not running a million times per update, dont worry

also your compiler will do magic anyways, so without looking at the assembly code, you cant tell whats going on anyways

[rustic ember]

Aight. Thanks

[tepid river]

the only relevant performance thing is: dont use Math.Pow if you can use x*x

[rustic ember]

Wait why not?

[tepid river]

because its for general exponent calculation and takes much longer

like, factor 20 or sth

[rustic ember]

Wow

Okay. Good to know. I very rarely use anything exponential anyways

[tepid river]

exponents and square roots are expensive.

[bleak thorn]

Why .main.startColor doesnt works?

[rustic ember]

If you hover your mouse over the red line, what does it say?

[bleak thorn]

this is not a variable

but...

[rustic ember]

SpriteRenderer.material.color is of type Color while ParticleSystem.main.startColor is of type ParticleSystem.MinMaxGradient

[rustic ember]

        ParticleSystem parSys = new ParticleSystem();
        SpriteRenderer ren = new SpriteRenderer();
        ParticleSystem.MainModule main = parSys.main;
        main.startColor = ren.material.color;``` This somehow works

        ParticleSystem parSys = new ParticleSystem();
        SpriteRenderer ren = new SpriteRenderer();
        parSys.main.startColor = ren.material.color;``` But this doesn't

Can someone explain why?

[bleak thorn]

like that?

[rustic ember]

var main = particleCollision.main

[bleak thorn]

ooh, thank you :p

[rustic ember]

You're welcome 😊

[buoyant crane]

the compiler should be smart enough to compile it to bit shift left 1 >> 1 (for ints at least)

[rustic ember]

Oh right. Does that work with float calculation as well?

[buoyant crane]

i was about to amend that

[rustic ember]

Ahah okay

[buoyant crane]

i’m not sure what it how it would optimize it for doubles

but better to assume the compiler knows best

[rustic ember]

Assets\TsTubeMove.cs(26,20): error CS1061: 'List<GameObject>' does not contain a definition for 'tranform' and no accessible extension method 'tranform' accepting a first argument of type 'List<GameObject>' could be found (are you missing a using directive or an assembly reference?)

help?

[buoyant crane]

List<GameObject> doesn’t have a .transform but GameObject does

[hybrid flare]

so remove < and >?

[buoyant crane]

no

[buoyant crane]

why are you using a list?

[hybrid flare]

i was struggling to add by prefab to the script

so was trying a list xD

[buoyant crane]

are you trying to store one object or multiple?

[hybrid flare]

one

😭

[buoyant crane]

Replace List<GameObject> with just GameObject

a list is a collection of GameObjects

[hybrid flare]

yea i tried that before and it kept giving a error

lemme try again

[buoyant crane]

so figure out why that errored

How to Create Cube Skin save system?

[hybrid flare]

ayy did it thanks

is there a way to pause all code mid game?

like if they die or somthing

[buoyant crane]

not exactly a pause, but you can set Time.timeScale to 0 and it basically freezes anything that relies on time delta to move

Hi,
how do I get the key of a directory?

// 
 Dictionary<Car, int> cars = new Dictionary<car, int>();
for(int i = 0; i< cars .Count; i++)
{
   Car _car = cars[i] //??? 
}

[simple egret]

You foreach, as Dictionaries usually don't have int indices

Here, you'd need to pass a Car to retrieve the int value bound to it

[knotty sun]

foreach (KeyValuePair<Car,int>

[simple egret]

If you need the Car from an int, then your Dictionary is backwards, or you're not using it properly

[solemn raven]

@knotty sun @simple egret Thanks a lot ❤️

[solemn raven]

nah , I need to loop through all of them regardless ❤️

[glad tusk]

For some reason, my code is generating the same random numbers every time it is run:

float randPosX = Random.Range(-6000f, 6000f);
float randPosY = Random.Range(-6000f, 6000f);

Debug.Log($"Twister {idx} - Random X: {randPosX}  Random Y: {randPosY}");

For more context, I start 3 coroutines that each call the same function where the above code is

Each coroutine generates a different random X and Y, but it's the same each time I run the game

Twister 0 - Random X: -1798.52  Random Y: -1830.727
UnityEngine.Debug:Log (object)
Tornado:GeneratePreSpawnData (int) (at Assets/CustomAssemblies/Twisters/Tornado.cs:248)

Twister 1 - Random X: -5659.34  Random Y: -73.58789
UnityEngine.Debug:Log (object)
Tornado:GeneratePreSpawnData (int) (at Assets/CustomAssemblies/Twisters/Tornado.cs:248)

If I stop the editor and re-run the game, I will get the same output

Is it possible to get a tile on a tilemap when it is using something other than 0 as a z level?

getTile() does not seem to allow this.

[prime wagon]

why is my default sprite doing this?

[simple egret]

Ask in #🖼️┃2d-tools

[indigo rampart]

Anybody got any advice for custom tiles. Say I wanted the player to place a tile, for example a factory tile. Which has a coroutine which basically just does something every X seconds.

So I create a custom tile, but there is no method 'OnTilePlace' or something like that which I can override to start a corouitine? Any ideas?

Is the only option to add the method to the tile and call the method when it gets placed?

example code:
tilemap.SetTile(tile)
tile.StartTimer()

You'll probably find the answer by copy and pasting your message to Google. Create a component with a method calling SceneManager.LoadScene and hook it up to the click event in button inspector.

[visual plinth]

Thanks but I already figured it out!

[stuck forum]

Is it possible to convert a TKey to int? I have a dict that uses an enum as a key and I need to get the element of the enum. Idk if dictionaries store anything in a order as a list or array though

[mossy gust]

hey guys, im trying to code a lazer script where there are 3 parts of the lazer, the top. the bottom, and the main lazer middle, and if you move the bottom, then the middle will rotate/ stretch to always be linked with it, but for some reason, the middle part always rotates 90 degrees and then rotates

and the stretching doesnt work

[leaden ice]

If it's an enum you can just cast it to int

int myInt = (int)myEnumValue;```

"TKey" doesn't actually mean anything. It's just the name of Dictionary's generic type parameter

[leaden ice]

Have you thought about using a LineRenderer?

[mossy gust]

whats that

[stuck forum]

So if let's say an enum has 3 diff values
Red
Green
Blue

And there is colors associated to each enum, red for red, blue for blue and green for green (let's call this someDict). if i make an array with the same colors in the same order (let's call this someArray), and i would want to compare if they are the same in some function, would it return true?

Compare(someDict((int)Red));

bool Compare(int element)
{
 return someDict[Red] == someArray[element];
}

edit: [] not ()

hope this makes any sense, im just experimenting with things atm

[leaden ice]

I have no idea what someDict((int)Red) means

is someDict a function?

is someArray a function?

they are written like functions in your example

[stuck forum]

some random Dictionary

[leaden ice]

How is it defined?

[stuck forum]

same for SomeArray, a random Color32 array

Dictionary<SomeColorEnum, Color32> i would guess where SomeColorEnum is the Enum with the 3 values

[leaden ice]

I think maybe here's the thing you're missing

enum Color {
  Red,
  Green,
  Blue
}```
This is implicitly the same as:
```cs
enum Color : int {
  Red = 0,
  Green = 1,
  Blue = 2
}```

so this:

bool example = Color.Red == (Color)0;
bool example2 = Color.Green == (Color)1;
bool example3 = (int)Color.Blue == 2;```

would all be true

enums are basically just a way to add fancy names to numerical values

they are stored by default as int, and can easily be converted via casting to and from int with that defined value.

By default they are numbered 0, 1, 2, etc... in the order they appear in the enum definition

[stuck forum]

yeah i got all that, but im just wondering how to compare an object in dictionary and an object in an array if one of them uses an Enum as a key and an int as a key, because with arrays i could make so that the second element is Red and it would automatically break then?

so i'd have to order things exactly in the same order in the array as the order of the values in the enum in order for it to be correct when comparing or whatever?

[leaden ice]

I don't think the array and dictionary are even relevant here

[leaden ice]

Dictionaries don't have an order

arrays do

[stuck forum]

yea exactly

[leaden ice]

so I'm a bit unclear what you're asking about here

[stuck forum]

this pretty much

[leaden ice]

I'm not sure what kind of comparison you're talking about though

[stuck forum]

if Red is the first value in the enum, would the color red need to be at element 0 in the array?

[leaden ice]

You can put whatever you want in the array

Red == 0 though

[stuck forum]

forget the comparison thing, i just took an example

[leaden ice]

You're saying if you want the array to work the same as the dict?

[stuck forum]

lemme think on how to explain this

[leaden ice]

Then whatever you mapped to Color.Red in the dictionary should be the first element in the array, yes.

I don't really understand why you would have both a Dictionary and an Array in this situation though

what would be the point of having both?

[glossy basin]

hello there, could somebody explain what ,, does in this array

[leaden ice]

This is declaring a three dimensional array of int called data

Since it's in parentheses I can only assume it's a parameter in a function or something.

Similar to float x; < just a data type and a variable name

[glossy basin]

Ohhh I see, is there any other way to initialize the array as 3 dimensional without ,,?

[leaden ice]

no

well there's jagged arrays

but that's a slightly different things

e.g. int[][][]

[glossy basin]

I see

[leaden ice]

that's an array of arrays of arrays of integers

similar but not quite the same

[glossy basin]

I want to convert that to a native array for processing in burst, is that possible?

[leaden ice]

Yes

just flatten it

all multidimensional arrays can be flattened to a 1D array

Then you just do a little math with the / and % operators to convert your 3D index to a 1D index

https://stackoverflow.com/questions/7367770/how-to-flatten-or-index-3d-array-in-1d-array

[stuck forum]

Because I made a menu manager system that basically switches between GameObjects (stored in an array) and it switches to the menu corresponding to the index I pass in the menu switching method. I was thinking of using this method generically so if I were to have for instance a pause menu or a main menu, I'd use it there. It has a constructor so it knows what menus are in it

I have, however, a method in a different class that takes in a GameMode enum which does different things (gets called by buttons), but should also show the right game mode settings menu (for customizing a match). problem is the enum/int problem I have right now since I am taking in an enum but it needs an int to switch menus. so I just made a dictionary with the same key (GameMode enum) that stores these menu objects and I just need to switch to the right menu corresponding to the selected game mode

[glossy basin]

Looks complex, I will give it a try, thanks!

[lunar forum]

So, if I have a singleton script, do I need to attach it to a game object and have it in my scene? It keeps telling me that I have an object reference not set to an instance of an object all the time.

[oblique spoke]

Depends on how you are implementing the singleton. If you are relying on Awake or some other Unity callback to set it up, yes.

[lunar forum]

Man. Singletons are confusing as hell.

[restive ice]

try to stay away from them as much as possible tbh, often you don't actually need singletons if you just structure your code better.

They make it very easy to start accidentally writing classes that have multiple responsibilities

and you want to stick to the Single Responsibility Principle as much as possible.

Anyway, does anyone know why one of my components returns null when added?

They both extend from UnifyBehaviour which extends from MonoBehaviour

oh I think I figured it out.. it has something to do with my assembly references

I had the FooMono behaviour in my edit mode test folder

it's kind of weird that it just becomes null instead of throwing me an error...

[lunar forum]

I cannot think of a solution to my problem other than singletons. Have to keep a persistent score and variables for multiple objects that are also accessible from multiple objects.

[restive ice]

a persistent score and variables for multiple objects that are also accesible from multiple objects?

wah?

can you give a more concrete example?

[hollow stone]

You can roll with one singleton, aka service locator pattern ( a bit more too it), you can roll with events (static or SO), you can roll with dependency injection (either something fancy zenject/extenject or by unity inspector/FindGameObject)

[hollow stone]

Are you using assembly definitions?

[modest nova]

I dont know what that means

if your asking if this is a library built by unity then yes

[hollow stone]

Ok. It's having an .asmdef file by your scripts to make it compiled into its own assembly file. If you do, you need to reference the transform package with this.

[modest nova]

I dont get it but okay XD

[chrome horizon]

Hi everyone! I was wondering if anyone could help me on a raycast thirdperson issue. Basically my raycast shoots to the centre of the world (no idea why)(Video: https://www.dropbox.com/s/qst0c00mgn6wzzr/Unity_mVZHCyrHU1.mp4?dl=0)

cam = GameObject.Find("MainCamera").GetComponent<Camera>();

 Debug.DrawLine(cam.transform.position, cam.transform.forward, Color.green); print("Hit");
        if (Physics.Raycast(cam.transform.position, cam.transform.forward, out RaycastHit hit, pickupDistance, pickupLayer))

[modest nova]

1.0.0

[leaden ice]

cam.transform.forward is not a position

So it doesn't make sense to use it in DrawLine

it's a direction vector

If you want to provide a direction vector, use DrawRay

DrawLine expects two positions

DrawRay expects a position and a direction

[chrome horizon]

I was using that before but it doesn't show where it lands

[leaden ice]

You need to conditionally draw different things when it hits or doesn't hit

[chrome horizon]

How do I do that?

[leaden ice]

when it hits you can do a DrawLine between the ray origin and the raycast hit

when it doesn't, do the normal DrawRay

[leaden ice]

Conditional code can be written with if and else in C#

[chrome horizon]

Do you have the code to drawline?

[leaden ice]

wdym

[chrome horizon]

The raycast is in an if

How do I display the raycast

[leaden ice]

Using DrawLine and DrawRay as we have been discussing 🤔

[chrome horizon]

When I use DrawRay it's like 2cm long

[leaden ice]

It's as long as you tell it to be

perhaps you should use pickupDistance as the length of the ray

[modest nova]

is
private readonly RefRW<LocalToWorld> localToWorld;
the same as
private readonly TransformAspect localToWorld;

[leaden ice]

no

[modest nova]

oh okay 😢 thanks

[leaden ice]

one has type RefRW<LocalToWorld> and the other has type TransformAspect

[modest nova]

transformaspect is not being accessed, I think it has been removed or my library is corrupted maybe?

[chrome horizon]

Debug.DrawRay(cam.transform.position, cam.transform.forward, Color.green); print("Hit");
        if (Physics.Raycast(cam.transform.position, cam.transform.forward, out RaycastHit hit, pickupDistance))//, pickupLayer))
        {

[hollow stone]

It was removed

[leaden ice]

why did you comment out the layermask?

[hollow stone]

https://docs.unity3d.com/Packages/com.unity.entities@1.0/changelog/CHANGELOG.html

[chrome horizon]

So that the if statement can hit anything so it's true

I thought that you meant before that you draw the raycast after the if statement

[leaden ice]

Yes

you need to draw after the raycast

that way we can tell if you hit anything or not

#archived-code-general message

[chrome horizon]

Like this?

if (Physics.Raycast(cam.transform.position, cam.transform.forward, out RaycastHit hit, pickupDistance))//, pickupLayer))
        {
            Debug.DrawRay(cam.transform.position, cam.transform.forward, Color.green); print("Hit");

[modest nova]

Thank you so much! It doesnt solve the problem but im one step closer

[leaden ice]

no we would only be doing DrawRay when we missed, as mentioned already.

[magic fossil]

I'm seeing GC allocs from calling .Add() on a dictionary. Is that to be expected?

[leaden ice]

shouldn't be... can you show the code?

[hollow stone]

Usually you only need the LocalTransform component

[chrome horizon]

What's the code to draw a line from the position to the landed raycast

[leaden ice]

Use DrawLine

and use the ray origin and the hit point

[modest nova]

got it, thank you so much, ill look into it

[chrome horizon]

Ah thats what I needed

[waxen jasper]

Can anyone take a crack at what I need to do to fix these errors? They're stopping me from creating a build.

[chrome horizon]

@leaden ice Ahh that looks so much better. It does seem to be colliding with my player, how can I work around that

[leaden ice]

I don't know anything about what you're doing or your game so IDK what that even means 😉

[leaden ice]

Are you using Visual Scripting?

[chrome horizon]

Oh yeah 😆 third person game using C#

How do I make a raycast ignore a tag?

[leaden ice]

you don't

that's what the layermask is for

[waxen jasper]

Is that what shader graphs use? if so yes

[leaden ice]

you make it ignore layers

[leaden ice]

no

shader graph is shader graph

visual scripting is different

If you're not using Visual Scripting just uninstall the package

[waxen jasper]

Oh. let me double check

[chrome horizon]

@leaden ice You life saving, cheers for the help!

[waxen jasper]

I really should stop skimming errors 😛 Looks like that was the culprit, seems kind of random though. Thanks! Believe I meant to thank @leaden ice but thank you too

[magic fossil]

Trying to replicate to share a minimum reproducible, but having trouble getting it to recur out of context 😕

[inner yarrow]

I've never really had this issue before, and to my knowledge I'm not doing anything unusual, but I am having a lot of my smaller rigidbodies falling straight through the floor. Any ideas how to fix this?

[leaden ice]

Like if you're doing something along the lines of

myDict.Add(key, new Someting());``` then it's the `new Something` with the GC alloc not the add

Also if/when the Dictionary resizes, it will allocate memory as well

[magic fossil]

I was thinking that could be the case. I'm creating a new struct - I thought structs didn't get GC Allocs?

[leaden ice]

structs stored in a dictionary are stored in the dictionary's internal arrays, which are in the heap

[leaden ice]

So this is relevant^

[glossy basin]

transform aspect was removed on the latest version of ECS

[leaden ice]

If you know ahead of time how many entries will be in the dictionary in advance it may be worth it to use the constructor with a capacity argument:
https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.dictionary-2.-ctor?view=net-8.0#system-collections-generic-dictionary-2-ctor(system-int32)

this will prevent unexpected allocations later on

at the expense of doing the allocation immediately

[inner yarrow]

Is there some sort of recommended minimum size for rigidbodies?

[magic fossil]

Got it, that's very helpful. That did narrow down the root cause and I was able to replicate it by initializing a dictionary of a small size and forcing the resizing.

[leaden ice]

You'll see similar behavior with any of the dynamically sized collection types in C# including List, Queue, Stack, etc...

[magic fossil]

Is it typically better to define the maximum capacity ahead of time if known, even if it's likely that the full capacity will not be needed?

[leaden ice]

well if you don't use it all, it's wasted memory

but if resizing happens - that can take additional time when adding things, since you might need to reallocate and copy the data, and this also produces garbage (in the form of the previous, smaller array which is discarded) as you see

So - it's a tradeoff

[magic fossil]

OK, makes sense. And the Garbage Allocation only occurs when the dictionary is resized because it discards the previous dictionary (and allocates to clean up the corresponding references on the heap)?

[leaden ice]

well it allocates a new one, and leaves the old one for the Garbage Collector to clean up, yes

the allocation is what is caught in the profiler I believe

[magic fossil]

I understand now. Thanks so much for your help! 🙂

[sweet marsh]

got a bit of a problem, I've got 2 layer one called "Ship" and the other called "MapView" I also have 2 cameras in the scene and i want each one to render one of the layers each. culling masks is the solutuion right? issue is when I hide "Ship" from the mapview camera it seems to stop rendering both layers

Culling mask settings:
Ship + MapView = everything rendered (intended)
Ship only = only ship rendered (intended)
MapView only = neither ship nor mapview rendered (unintended: mapview should be rendered)

[leaden ice]

Make sure the actual renderers are on the correct layers

Someone who's good at math, how would you calculate a direction that is perpendicular to another direction (or in other words, given the normal of a plane, find any direction that travels along said plain).

[unkempt sail]

[night harness]

Is there a way to limit a UnityEvent to specific functions, and possibly pre-load a specific class?

Just to make the inspector more designer friendly

[unkempt sail]

you can make it pre-load instances of components, but not really limit shown functions

it basically shows all public functions specific to that class

[night harness]

Yeah makes sense, figured there might of been a niche feature to do it. not a dealbreaker just would have been nice

How would I go about pre-loading a specific instance? in this case i just want it to be itself

[unkempt sail]

yeah I must've mistaken something, you can't set object instance

[stray stratus]

it seems like a profiler is where you can check performance, is that correct?

[unkempt sail]

what you can do is write a custom editor I guess, that takes in a specific type in its definition like CustomEvent<Player>, maybe also add a function attribute to public functions that makes it seen to that editors dropdown

[unkempt sail]

sorry not profile, read this

https://docs.unity3d.com/Manual/configuring-project-for-xr.html

[slow grove]

Hey guys, what's the new input system's equivalent to Input.getAxis("Mouse X") and mouse Y respectively? Using the Delta [Mouse] path seems to have a lot less precision than that

[soft shard]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/api/UnityEngine.InputSystem.Pointer.html#UnityEngine_InputSystem_Pointer_delta

The delta will tell you how far from 0 the mouse moved that frame, is that what your looking for?

[slow grove]

I think that's what I'm using right now:

This one just seems a lot more jittery because it uses discrete pixel values rather than some smooth function from -1 to 1..

aand I just realized I can probably divide it by the screen width and height to smooth it out

[soft shard]

AFAIK, it just gives you the difference the mouse moved, so it likely would be much larger than -1 and 1, im not sure if dividing that difference by the screen resolution would give you a smoother value, though you can try it, or multiply it by deltaTime, or I think you should be able to add a processor to clamp or normalize the value, but depending on what your trying to do, you could just check if the difference is less than 0 or not

[unkempt sail]

you can try Mouse.current.delta.ReadUnprocessedValue()

[polar marten]

i think it is indeed just the delta binding

[unkempt sail]

the new input system is so finicky

[wet condor]

why my wheel collider and lines are not the correct manner ?

[slow grove]

Seems to do the same thing as the Delta [Mouse] path in the input controller

[cobalt wave]

what would the "correct" manner be?

[wet condor]

my line should be on the that circles. but i dont know why it Maked like this.
when i use 4 tires they are place correctly

[cobalt wave]

and how do you generate those lines? I assume the circles are the wheel colliders

[wet condor]

oh wait i thought it created cuz of coliders.
i guess it's in the kit i use

[stable osprey]

anyone has any tips & tricks for integrating Epic Online Services SDK to a Unity game?

[plucky inlet]

5 Sec google search... https://dev.epicgames.com/docs/epic-online-services/eos-get-started/eossdkc-sharp-getting-started?sessionInvalidated=true

[stable osprey]

wow you're so good

must be years in the industry huh

[plucky inlet]

google term "unity epic games sdk" ... not really a fact of experience 😄

[stable osprey]

ok sry i'm tilted because this is still a headache after days of trying 😄

[plucky inlet]

Did you try that page already and have issues? Or did you just not find it?

[stable osprey]

yeah that's where I downloaded the SDK from 😛

am hoping more like.. tips on what libs/APIs to ignore, any actual code samples that made it work, or if I could use any shortcuts (e.g.: https://github.com/PlayEveryWare/eos_plugin_for_unity -- which seems kinda obsolete), etc

[plucky inlet]

Why not just use that sdk with its tutorial dwon the page. They even made a Unity script example on how to use it. So maybe try to add this and come back when you are stuck 🙂

https://dev.epicgames.com/docs/epic-online-services/eos-get-started/eossdkc-sharp-getting-started?sessionInvalidated=true#unity-eossdk-component

[stable osprey]

cool, thanks

[open wasp]

my scroll rect is overflowing and putting a mask or rect mask 2d breaks the ui really badly. is there another way to hide the scroll rect behind other ui?

[stable osprey]

it'll work properly if you put a background behind it

leave the mask on, and just add a black image on a GameObject that's first in the UI canvas's hierarchy

[open wasp]

it's on a panel and the panel i want it to render behind is not rendering on top of it

[stable osprey]

is that resolution correct? 1242x2208

anyway

[open wasp]

it is phone resolution

dont mind

this is a mobile app

[stable osprey]

so the upper part definitely doesn't have a background

are yu sure you're not turning the main panel off while scrolling?

the issue you've shown would be caused if there is no background and camera doesn't clear. No other cases 😛

[open wasp]

as in just an image behind it?

[stable osprey]

yup

seeing you don't have a camera in the scene, it definitely doesn't clear

adding a camera in the scene would also fix it, but you'd be left with the default Unity background -- likely something u don't want in UI apps

[open wasp]

i get this issue instead

should i just stick a camera back in?

[stable osprey]

seems you're scrolling the container of the rect instead of the scroll rect content

I'd say create a default scroll rect and work from there without changing the references -- or check where the proper references go, and copy that to your Scroll Rect

[stable osprey]

yeah content shouldn't be the viewport -- Content var should be referencing the 'Content'

[open wasp]

oh wait

i didnt realize i did that

[stable osprey]

easy to mess up, lol

while you're at it, pump the scroll sensitivity up to 40 or 70. It's much better for in-editor testing

[open wasp]

thx, i got it working perfectly now

didnt realize i was just small brained

[stable osprey]

lmao.. no definitely not that.. Unity UI is a pain to get started with.. especially scroll rects and layout groups

[fading yew]

Hey all, I recently openned an old project and I'm getting these annoying errors (Google and ChatGPT have been useless). I've deleted the library folder, made sure all my packages are up to date and I've tried on a different Unity version. Any ideas? 🙂

[plucky inlet]

Backup your project and remove the library folder to let unity rebuild it. Seems like there might be some packages being cached and are not working anymore in your editor

[fading yew]

I've already deleted the library folder*

I also did a "Re-import all" which I presume does about the same thing

[plucky inlet]

Did you update your editor you are opening that project with?

[fading yew]

yep! On the latest LTS first, then on the beta as a test

[plucky inlet]

Than I guess you are just using packages which are not preview state any more. Didy ou check your packages?

[fading yew]

yep

[plucky inlet]

Maybe you have to look at your packages json file

[fading yew]

You think the manager window would not show the update and I have to manually update it there?

Is there an easy way to know what the latest version for these are?

[plucky inlet]

I think they are not even part anymore of packages and should be removed, but I am not sure, what was the original editor versino of your project?

[fading yew]

I don't know :/ must have been about a year old :/

[plucky inlet]

Ah okay, I think you can show hidden packages, one sec

[fading yew]

Yeah there use to be an option in the little dot menu, but I can't find it anymore 🤔

[plucky inlet]

Try to click advanced settings and Show dependencies, then reopen packagemanager and see if there is any update for you

[fading yew]

alright I'll try tthat! unity is restarting...

I tried resetting to default and although it seems to help, it's also not really doable because it gets rid of all my custom packages I no longer even have in "my assets". So I rolled back on git

Also, I don't see "advanced project settings" but here's the "project settings" windows. I don't see anything about "show dependencies"

I think you're onto something with editing the manifest manually. But I'm not sure where to find the right version for every package :/

(thank you for your help btw 🙏 )

[plucky inlet]

How does your package-lock json look like?

[fading yew]

I'll send it to you asap, I tried reseting the packages again but this seems to not just reset to default but entirely remove ALL packages ^^' including unity built in ones...

so this is what I see right now ...

I'll rollback once more and give you the lock file! 1 sec

[fading yew]

It looks normal to me, would you like me to share the file here?

[plucky inlet]

I can tell you, that there is no single platform entry on my current project for example

[paper heart]

I want to graphics.copy from rendertexture to texture2D, they are both RGB565 with mip maps off and same resolutiob, but it throws mismatch error

[plucky inlet]

what type is texture and the other one?

[paper heart]

source is Render Texture RGB565 with resolution 32x32 and mip mapping off, dest is Texture2D RGB565 with resolution 32x32 and mip mapping off

[plucky inlet]

You might have to convert your rendertexture to a base texture, because texture2d and rendertexure are both different inheritance from texture itself

[steady granite]

I have this error in console which points to this line where I set DontDestroyOnLoad to elements in a list referenced in the inspector.
When debugging in visual studio, I don't have any error on these lines and it goes through the rest of the code fine.
It doesn't seem to cause any issue, but I still wonder why it shows up?

[plucky inlet]

Are you trying to dontdestroyonload items from your project folder structure?

[steady granite]

no, gameobjects in the same opened scene as this script

[fading yew]

Sorry had to go, I'll try deleting these entries then! Cheers!

[vague slate]

Is there a way to have 1 ParticleSystem to spawn particles in different places?
For example I move it to position X. Spawn particles. Then move it to position Y and spawn particles. So that previous particles stay intact in previous spot.

[thin aurora]

Does reopening Unity change anything?

[rustic ember]

How can I get the lowest value from a List<int> using a lambda expression?

[thin aurora]

List.IndexOf + List.Min()

[rustic ember]

Great. Thank you 🙏

[tepid river]

i would guess spawning the particles in worldspace?
not sure if they then get detached

thinking of it, yes it works, doing exactly that

[steady granite]

Absolutely, always takes some time before I think of rebooting Unity, but it works so often 😅

[thin aurora]

No problem, always try a restart with these internal errors 😄

[rustic ember]

Does List.IndexOf(value) get the first element in the list with the value value?

[thin aurora]

Yes

Otherwise use LastIndexOf

You can overload IndexOf with arguments if you want a different occurance

Such as list.IndexOf(2, list.IndexOf(2) + 1); to get the second 2 in the list.

[cosmic ermine]

wondering does anyone know how the constructor for Color works? is it the same as a simple Vector4 or does it do something special to it? (it would take too long to explain why this matters...)

[severe coral]

does anyone know why some of my stuff is disappearing while im in scene view?

[cosmic ermine]

I've had this issue before! It seems to be triggered from zooming in and out too many times! Somewhere in scene view should be something to help you fix it, although I can't remember where sorry...

[severe coral]

ah alright thanks i'll have a look

[cosmic ermine]

wish ya luck!

[severe coral]

tyty

[ember ore]

Is there any lib/plugin that adds some sort of ingame console to a unity app?
That can be opened and viewed to see logs n stuff?

[severe coral]

fixed it by pressing ctrl f on an object and that seems to reset the zoom

[calm heath]

is there a way to draw 2d spline maps instead of having to customize it with a sprite and dragging all the dots around

[cosmic ermine]

good job!

[trim schooner]

It’s just F

Also, this is a channel for questions about code

[tepid river]

probably the editors camera near plane.
cameras stop rendering things if they are closer than that "imaginary" plane

not sure how to change that, noticed similar things

[calm heath]

how can i join these together

[tepid river]

there it is

seems that dymamic clipping gets confused

[tepid river]

right click, add empty parent

[calm heath]

where is it

[severe coral]

ah thank you

[dusk geode]

when you use the animation rigging package can you mix procedurally generated animations with traditional animations ?

[rustic ember]

Is this valid code? ```cs
public PlayerState state;

public enum PlayerState
{
    Moving,
    Falling,
    Idle
}

// Start is called before the first frame update
void Start()
{
    int playerState = (int)state;
}```

If state == PlayerState.Moving I want playerState to be 0

If state == PlayerState.Idle, I want playerState to be 2.
And what does state.ToString() do? Will it say Movingor PlayerState.Moving?

[orchid bane]

public class LevelButton : MonoBehaviour {

I have this code which sets which scene to load with my button. It works fine on my PC but always loads the first level on my phone(
Any ideas how to fix it?

[steady moat]

I am not really sure, but PlayerPrefs.GetInt("CompletedLevel", 0) seems like a terrible idea for save.

And, it seems like you actually need to call PlayerPrefs.Save() to propagate the change. https://docs.unity3d.com/ScriptReference/PlayerPrefs.Save.html

So, maybe you are not doing it ?

[orchid bane]

Ohhhhh wait

[steady moat]

And, did you include the scene in the actual build ? https://docs.unity3d.com/Manual/BuildSettings.html

[tepid river]

i wouldnt cast enums to integers, if its not absolutely necessary.
the whole reason for enums to exist is that integers are hard to read and messy

with enums, switch is your friend

switch (state) {
  case PlayerState.Moving:
    playerState = PlayerState.Owo
    breaK;
  default:
    throw new UwuException();
}

[rustic ember]

I guess. But then I need to manually convert it to an integer

Because I need it to pick an element in a list

[tepid river]

show that code

i bet you 2 cookies that you dont

🍪 🍪

[rustic ember]

    public Transform[] abilityObjs;

    public void AbilityButtonUpdate(Ability.AbilityType _type)
    {
        abilityObjs[(int)_type].gameObject.SetActive(true);
    }```

[rustic ember]

Essentially

[tepid river]

you could use a dictionary instead that maps AbilityType to object.

[rustic ember]

But why?

That's just a bigger mess

[tepid river]

because as soon as you reorder your ability enum, f.e. by adding a new state in the zero place, your array breaks

[modest nova]

What component do I have to add to my entities to make them fall using gravity

[tepid river]

your code works, but its not safe to changes

[rustic ember]

Yeah. But I won't. This way I can easily assign the Transforms in the inspector, which isn't as easy with Dictionaries

[tepid river]

rigidbody

[modest nova]

cant use rigidbody on entities

[rustic ember]

Great. Thank you

[warm wren]

then code the gravity i guess

[modest nova]

yeah I guess thats the plan then, I actually needed everything but I think Ill have to use another physics system

[jaunty plume]

Hello, i have a problem:

{

    SpriteRenderer[] spriteRenderer;
    void Start()
    {
        spriteRenderer[0] = GetComponent<SpriteRenderer>();
        spriteRenderer[1] = GetComponentInChildren<SpriteRenderer>();

    }
    void FixedUpdate()
    {
        float screenHeightInWorldUnits = Camera.main.orthographicSize * 2f;
        float scaleFactorY = screenHeightInWorldUnits / spriteRenderer[0].sprite.bounds.size.y; // THIS IS LINE 18
        spriteRenderer[0].transform.localScale = new Vector3(scaleFactorY, scaleFactorY, 1f);

        float screenWidthInWorldUnits = Camera.main.orthographicSize * 2f;
        float scaleFactorX = screenHeightInWorldUnits / spriteRenderer[1].sprite.bounds.size.x;
        spriteRenderer[1].transform.localScale = new Vector3(scaleFactorX, scaleFactorX, 1f);

    }
}

So, if i run this code, it will say:
NullReferenceException: Object reference not set to an instance of an object
ScreenAutoFit.FixedUpdate () (at Assets/ScreenAutoFit.cs:18)
(Line marked on code)

I cant understand, i even put the lines from start together with fixedupdate and still doesnt work

[leaden ice]

Do you have a camera with the MainCamera tag?

[dim spindle]

Read the error

[jaunty plume]

havent touched the camera so it must have the tag

yup

[leaden ice]

Check

[jaunty plume]

it haves

[leaden ice]

Ok well NRE is always the same

Read your error

Go to the line

[prisma birch]

What would be a good way to have a nav mesh agent calculate a path to walk around other agents? I want to keep my enemies spread out further from one another rather than bunching up. I can increase the avoidance radius, but that just makes the agent that is in motion push the other agents out of the way rather than having the agent walk around the other agents.

[leaden ice]

Figure out what's null

[jaunty plume]

i tested by putting the spriteRenderer to debug log and i got it on that debug line

[leaden ice]

It has no sprite

Or the array itself is null

[jaunty plume]

this is the object thats linked to the variable

[leaden ice]

Because you never initialize the array

You never initialized your array

It's null

And you're getting an error in Start too

[jaunty plume]

i've intialized on start

[leaden ice]

No you didn't

[jaunty plume]

nah i dont

huh?

[leaden ice]

Where?

Not in that code

[jaunty plume]

huh?

wdym

[leaden ice]

You would need spriteRenderer = new SpriteRenderer[2]; for example

Right now your array is just null

[jaunty plume]

you meant this one?

[leaden ice]

Yes

It's not initialized

Anywhere

[jaunty plume]

wait

i have to initialize the whole array? not just elements?

[leaden ice]

Also both of those GetComponent lines will return the same object

[leaden ice]

Arrays are objects themselves yes

[jaunty plume]

i have as children an object with spriterenderer component

wait

[leaden ice]

Doesn't matter

GetComponentInChildren checks the object itself first

[jaunty plume]

what

[leaden ice]

You'd do transform.GetChild(0).GetComponent

[jaunty plume]

oh

[leaden ice]

Or just assign it in the inspector which is better

[jaunty plume]

yea

lemme do it

good

[opal cargo]

Hey guys, how can I out an empty raycast in case my function did not hit anything so my code won't throw a null reference exception?
I can't even let the out variable empty, so there has to be some value in it and I can't come up with an idea 😕

private bool CastSelf(Vector3 pos, Quaternion rot, Vector3 dir, float dist, out RaycastHit hit)
{
        // Get Player Capsule params
        Vector3 center = rot * _playerCapsule.center + pos;
        float radius = _playerCapsule.radius;
        float height = _playerCapsule.height;

        // Get top and bottom of Player Capsule collider
        Vector3 bottom = center + rot * Vector3.down * (height / 2 - radius);
        Vector3 top = center + rot * Vector3.up * (height / 2 - radius);

        // Check for hits in given direction and distance, return nearest object as RaycastHit if possible
        if(Physics.CapsuleCastNonAlloc( top, bottom, radius, dir, _tempHits, dist, ~0, QueryTriggerInteraction.Ignore) > 0)
        {
            IEnumerable<RaycastHit> hits;
            hits = _tempHits.Where(hit => hit.collider != transform);
            float closestDistNonAlloc = Enumerable.Min(hits.Select(hit => hit.distance)); 
            IEnumerable<RaycastHit> closestHitNonAlloc = hits.Where(hit => hit.distance == closestDistNonAlloc);  
            hit = closestHitNonAlloc.FirstOrDefault(); 
            return true;
        }
        else
        {
            hit = _tempHits.FirstOrDefault();  // << Can't be empty, still gives error like this
            return false;
        }
}

[jaunty plume]

this was the solution

[leaden ice]

Usually you just do hit = default; when there's no hit

[opal cargo]

OK, that's easy, convenient and I was not aware of this 😄

Works, 2 hours wasted - Thanks 😄

[jaunty plume]

2 hours, that's amateur number

[opal cargo]

Will try harder next time 😉

[cold parrot]

We pick implementation strategies on likely number of hours wasted

[finite plinth]

is there a way to duplicate only the mesh renderer parts of an object?

as right now im instantiating an object and then destroying each script component afterwards

however that is causing errors with both awake methods and scripts that depend on eachother

so im wondering if theres a way to skip the destroy part and only spawn the necessary rendering components upon instantiate

[hexed pecan]

Create an empty object and add a mesh renderer and mesh filter, copy over the materials and mesh

[finite plinth]

i will try that, thank you

[opal cargo]

Again maybe a n00b question, but I've added a Layermask to my Raycast to ignore the Player, which itself and all childrens were assigned to - but I'm still getting hits from it
Physics.CapsuleCastNonAlloc( top, bottom, radius, dir, hitArray, dist, ~LayerMask.NameToLayer("Player"), QueryTriggerInteraction.Ignore)
Any idea?

[leaden ice]

NameToLayer is not how you make a layermask

LayerMask.GetMask

[opal cargo]

Well, works again, kinda got the Docs wrong

[indigo rampart]

Anybody got any advice for custom tiles. Say I wanted the player to place a tile, for example a factory tile. Which has a coroutine which basically just does something every X seconds.

So I create a custom tile, but there is no method 'OnTilePlace' or something like that which I can override to start a corouitine? Any ideas?

Is the only option to add the method to the tile and call the method when it gets placed?

example code:
tilemap.SetTile(tile)
tile.StartTimer()

[steady moat]

You could create a class that wraps the TileMap that can be use to include events.

public class MyOwnTileMap : MonoBehaviour {
  [SerializeField] private TileMap tileMap = null;

  public event System.Action<...> OnTilePlaced;

  public void SetTile(...) {
    OnTilePlaced?.Invoke(...);
    tileMap.SetTile(...);
  }
}

Alternatively, you could try to implement your own tile and trigger an event whenever the tile is created. However, beware to not use the Tilemap as a way to store/update your tile. You should try to limit your usage of the tilemap to render function exclusively.

what do you mean

[thin aurora]

🤔 Asking Questions is very useful for you

[sonic night]

yes

[lunar forum]

How do you reference a game object's script? I have a script attached to an otherwise empty game object called "Logic" and the below code is trying to reference that code so I can use its methods. But I'm hit with an "object reference not set to an instance of an object" error.

{

    Logic l;
    Color pickupColor;
    SpriteRenderer driverSprite;

    // Start is called before the first frame update
    void Start()
    {
        l = GameObject.FindGameObjectWithTag("Logic").GetComponent<Logic>();
    }```

The object is in the scene, so I know it's not an issue of there not being an instance of it.

Also, feel free to point out the other dozen things wrong about that short snippet of code if you'd like. I feel like I'm doing everything wrong.

[leaden ice]

If you're getting an NRE with this code then FindGameObjectWithTag("Logic") is returning null, meaning no active object with that tag was found.

Is there a good reason you aren't just assigning your reference in the inspector?

[thin aurora]

[valid adder]

I'm writing a grid system but I have a mathematic problem with getting the node from a world position. I basically wanna snap to the node as soon as the target is inside the square around the node (the unity grid is representing the square i mean). However as you can see in the video this is not working right now.

public Node NodeFromWorldPoint(Vector3 worldPosition) {
        float percentX = (worldPosition.x + (width / 2f)) / width;
        float percentY = (worldPosition.z + (height / 2f)) / height;
        percentX = Mathf.Clamp01(percentX);
        percentY = Mathf.Clamp01(percentY);

        int x = Mathf.RoundToInt((width - 1) * percentX);
        int y = Mathf.RoundToInt((height - 1) * percentY);

        return nodes[x, y];
}

public void CreateGrid()
    {
        nodes = new Node[width, height];
        
        var name = 0;
        for (int x = 0; x < width; x++) {
            for (int y = 0; y < height; y++) {

                Vector3 startPosition = new Vector3((width) / 2, 0, (height) / 2) - new Vector3(0.5f, 0, 0.5f);
                Vector3 worldPosition = (transform.position - startPosition) + new Vector3(x, 0, y);

                nodes[x, y] = new Node(true, worldPosition, x, y);
                if (visualizeNodes) {
                    nodes[x, y].createInstance(nodeInstance);
                }
                name++;
            }
        }
    }

How would I tackle this issue? What mathematical mistake have I made?

[wanton stratus]

Can anyone suggest me how many programming patterns i should know for developing hyper casual games fast

[stable rivet]

this is a very vague q that doesn't really have an answer. what do you consider "hyper casual"? how big are these games? how fast are you expecting to develop these games?

in any case, understanding programming patterns doesn't really yield a faster rate of production. it'll just make your code more structured and maintainable.

My playerobject is destroyed when it sits on the floor, it has a bouncy rigidbody, which might be the cause. How do I fix this?

Nice!! Thanks! Thanks a great way of doing it, I wouldn't have thought of that. And thanks for the tip about not using it too much 🙂

[hallow grove]

hey everyone, I want to create a save system and for that i'd need each object to have a unique, permanent ID. However I can't find anything that allows this (GetInstanceID is not permanent so it won't work) does anyone has an idea on how to create a permanent ID system or is there already something like that in Unity ?

[winged mortar]

Guids?

They won't be the same on every system though

https://learn.microsoft.com/en-us/dotnet/api/system.guid.newguid?view=net-7.0

You could use an editor script to automatically assign a guid to every gameobject, that way it would be the same for everyone

[hallow grove]

ok thanks a lot !

[hallow grove]

thats not a problem

[winged mortar]

[thin aurora]

Do you need a unique id because you need to ensure that the saved data is returned to where it was saved from, or just saving in general?
If saving in general, either an unique guid using Guid.NewGuid() or you can use a regular int. For the latter you should check what the last int was that was saved, which is more work.
If you need to keep track of the class that saved it, why not get the full name of the class? typeof(yourClass).FullName

[hallow grove]

I need a unique ID for each object that needs to save data

thats why i want each object to have a unique and permanent ID

https://forum.unity.com/threads/solution-save-a-prefab-with-a-generated-mesh-es-without-creating-assets.463496/

[rain minnow]

bc you keep setting the agent destination to target at the start of every frame, then you use MoveTowards to set its destination (not sure why as this is the destination or end position for the unity to move to) when it's not yet at its current waypoint. the agent moves on is own . . .

Anyone know what could be causing this jittering? I only have a Character controller script in the scene.

[clear umbra]

are you using FixedUpdate?

[pliant lake]

an idea ? I searched on the internet but no topic about this prblm on unity and the available topics was about js and webAPI permissions in short nothing to do I really don't know where it can come from, I tried on the beta 2023 of the software and there on 2022.2.12 both times with HDRP and same problem for both versions :/ thanks for any help!

[swift falcon]

Horizontal rotation and headbob are on update. vertical rotation is on late update

[clear umbra]

are you lerping the camera?

[swift falcon]

only for the headbob

[clear umbra]

try disbaling the headbob is it still jittering?

I'm not sure how you implemented the headbob, but I have a suspicion it is causing the jitter

Otherwise, remove one part of your movement script at a time and test that the functionality is indeed working without jitter

(Test only Horizonal rotation, then only Vertical rotation, then Only Headbob, then start combining variations of these systems together until you find the culprit)

[thick isle]

I have a list that I am trying to populate from the Inspector, however I think I'm missing something

[Serializable]
public class CharacterStat{ //does base functions
}
[Serializable]
public class HealthStat : CharacterStat
{
//Does health specific things
}
[Serializable]
public class MovementSpeedStat : CharacterStat
{
//Does movement speed things
}

This is my parent child set up for stats to inherit functions but also manage their own specific stuff. I'm struggling to be able to add these individual classes to a list

    [SerializeReference] public List<CharacterStat> statList;

What am I missing here?

[hexed pecan]

Does it help if you initialize it?cs [SerializeReference] public List<CharacterStat> statList = new List<CharacterStat>();
Just wondering if that matters when using SerializeReference

That's what I've been doing, though my List's <T> has been an abstract class or interface

[thick isle]

oh let me try I thought about doing that but never ended up testing

[hexed pecan]

Its also initialized in the doc examples so that might be it

[thick isle]

hmm still no dice, I'd imagine its someweird inspector thing because they are just classes and not monobehaviors? i dont know :c

[hexed pecan]

The doc also says that SerializeReference should not be used for UnityEngine.Objects (which MB are) so thats not the issue

What if you make a new list variable just to test? And give it an initial value

Are you sure that CharacterStat does not inherit from any UnityEngine.Object class?

[thick isle]

nope, the class declaration is just public class characterStat

no inheritance

[somber nacelle]

are you sure you want to use SerializeReference there?

[inner yarrow]

I'm getting confused with what should be a pretty simple raycast. if(Physics.Raycast(ray, out hit, rayLength, LayerMask.GetMask("Lightsaber"))), it correctly only hits objects that are on the "Lightsaber" layer, but the object returned by hit.transform is the object's parent.

[hearty perch]

it matches

Well don't do that, the bot gives you false advice which you can't spot with your level of knowledge

i'm guessing the parent object has a rigidbody on it?

[hexed pecan]

hit.collider will reliably give you the actual object you hit

[inner yarrow]

Oh, thank you. I thought it returned the collider instead of the rigidbody

[hearty perch]

OOOOH THAT WAS WHAT class name

dang

[somber nacelle]

if you want the collider use hit.collider then you can grab the transform from that. since it's a child of a rigidbody it becomes part of a compound collider which means some properties for the raycast hit will point to the rigidbody object

[inner yarrow]

Yeah, I'm using hit.collider now thanks.

[lunar forum]

So, i've been working on implementing this way of doing it, but still getting the same error.

[teal silo]

Hey all, I want to create an enemy that has a sphere (or circle, since it's 2D) of influence that increases a certain stat of the players when inside it. Right now I have it set up with an empty child on the enemy, a sphere collider on said child and a OnTriggerStay2D that executes the code. Then, I made sure that the physics from the player's hitbox wouldn't affect the trigger because the player could hit the enemy through the trigger lol.

It works as intended, but I just get the feeling that changing the physics collisions seems kinda messy and not very good praxis, so I was wondering if any of you would have done it/would do it differently.

And while I'm at it, Id also like to ask what you guys would think is the best way to check if the enemy is facing away from the player or not (I would like to implement a backstab feature)

[hearty perch]

hey um

using UnityEngine;
using UnityEngine.SocialPlatforms.Impl;


public class trow : MonoBehaviour
{
    public SpriteRenderer sword;
    public Rigidbody2D rb;
    private float dirX = 0f;
    [SerializeField] private float moveSpeed = 7f;
    public Rigidbody2D rb2;
    public Transform transform;
    void Update()
    {
        dirX = Input.GetAxisRaw("Horizontal");
        if (Input.GetKeyDown(KeyCode.T) && sword.enabled == true);
        {
            rb.velocity = new Vector2(dirX + moveSpeed, rb2.velocity.y);
            if (transform.localScale == new Vector3(-1, 1, 1))
            {
                rb.velocity = new Vector2(dirX - moveSpeed, rb2.velocity.y);
            }
;
            
        }
    }
}```

here

when i press t and sword is on

i want to shoot it

shooting is working

something simmilar

but

when i spawn in game

[somber nacelle]

; ending your if statement early

[hearty perch]

it does it immediately

[hearty perch]

oh

i do have that

[hearty perch]

this

[somber nacelle]

then you should have seen the warning about a possibly empty if statement

[hearty perch]

mb

but still

it immediately shoots sword

[somber nacelle]

well if you've removed that ; then it shouldn't unless there's some other context you aren't providing

[hearty perch]

ok

imma fix that later

but now uh

look at this

there is missing ;

at if sentance

when i fix it

it doesnt work the way i want

when i dont

it works way i want

like

it works so what sword shoots at way im looking

if i dont fix it

if i do it just goes to 1 direction

to the right

[somber nacelle]

you still have the extra ; on your if statement. it's literally right next to your cursor. remove it

[hearty perch]

this?

[somber nacelle]

yes

[hearty perch]

okay

its all broken now

it doent move if i wont move

and skips sliding part

just teleports to where it would have been if i moved

[hard sparrow]

So I'm trying to refactor in order to have my unit data in a scriptableobject separate from the unit controller - the unit data contains the unique variables and logic for different units (different class for each one), and is executed by the controller (which is generic). Is that dumb?

[hearty perch]

oooH

this is the diffrance

thats pointless ngl

[winged mortar]

Okay so you don't need to add the {} to use the if statement

That's why the ; is valid syntax

Watch

[hearty perch]

so i do not need {} ?

uh

[somber nacelle]

in your case you do

[hearty perch]

good

[winged mortar]

if (X > y)
      doSomething();

Is the same as

if(X>y)
{
    doSomething();
}

[somber nacelle]

you can exclude the braces only when there is a single statement in the scope of the if statement

[hearty perch]

OOOH

[hard sparrow]

maybe it's dumb because the data will need to refer to variables in the controller (because those might be different due to in game effects)?

[hearty perch]

i didnt knew that

[winged mortar]

However the first approach only works with a single statement

[hearty perch]

thanks for telling me

[winged mortar]

And is prone to errors

[somber nacelle]

also you should consider asking questions in #💻┃code-beginner moving forward. especially if you don't know basic c# syntax

[winged mortar]

So you should always use {}

and just having a ; is a empty line

So nothing will be done on that line

thus having an if followed by a ; is just and if this then do nothing

[hearty perch]

thanks a lot! i understand now

[winged mortar]

if (X > y);

Is the same as

if(X>y)
{
    ;
}

[hard sparrow]

Are you just not supposed to put logic inside scriptableobjects?

[somber nacelle]

you can. but a lot of people will recommend against it and recommend using scriptable objects only for immutable data

[hard sparrow]

So if you have units with potentially unique variables and methods, you might as well just not bother with SO?

As in, an SO won't be sufficient to describe the unit

[somber nacelle]

you can, that's perfectly fine. but if you need to access those unique variables and methods but you've stored the reference to the SO as its base class you'd need to downcast to the correct type to access them

[winged mortar]

You can also convert a scriptablw object to a runtime object, so if a entity can shoot add an enum that it can shoot or melee and then at runtime check which ome is set when instantiating it

[hard sparrow]

In this case I would need to have a separate set of variables on the instance controller since those can be changed by in game effects (while you wouldn't want to change the base data). So then you'd be using the instance for both logic and variables so... does the SO serve any purpose at that point?

[hard sparrow]

Could you give an example?

[somber nacelle]

https://www.c-sharpcorner.com/uploadfile/scottlysle/downcasting-in-C-Sharp/

[winged mortar]

If you are building your things in runtime anyway SOs don't make any sense to me atleast

[hard sparrow]

Well every time I try to use SOs they end up just not making sense to me

I guess it's just for simple data and that's it

Also that static switch case example seems just bad

I'll just give up on SO for now

[winged mortar]

Can build a system using reflection to get behaviours bound to enums

Don't need a switch case

[mystic ferry]

I'm trying to implement a timer that kicks off some methods. I can't use a traditional deltaTime timer (afaik) because this timer is happening inside of an event listener. My solution was to use a simple coroutine with a waitforseconds, but that doesn't seem to be working how I thought it would

void OnStartNewRound()
{
   //some other things
   StartCoroutine(KickoffTimer(timeToWait));
   //the rest of the setup
}
 IEnumerator KickoffTimer(float timeToWait)
   {
      yield return new WaitForSeconds(timeToWait);
   }

any input as to what I'm doing wrong here?

[somber nacelle]

a coroutine will not delay the method it is called from, it can only delay itself (or technically it could delay another coroutine if the startcoroutine call is yielded in that outer coroutine)

[mystic ferry]

I see, that was what I was afraid of

what can I do to get the effect that I need?

[somber nacelle]

put everything you need to do inside the coroutine and have OnStartNewRound call the coroutine, or subscribe to whatever event with a lambda that just starts the coroutine

[mystic ferry]

gotcha. Thanks

[opal cargo]

Hi guys, got a bit weird behaviour with sorting an array that sometimes only has one item.

int hitLength = Physics.CapsuleCastNonAlloc( top, bottom, radius, dir, hitArray, dist, ~LayerMask.GetMask("Player"), QueryTriggerInteraction.Ignore);
if(hitLength > 0)
{
    for(int i=0; i < hitLength; i++)
    {
        Debug.Log("Hitlength:"+hitLength + " Hit"+i+": " + hitArray[i].normal + " name: " + hitArray[i].collider.name);
    }
    // Sort array by distance 
    Array.Sort(hitArray,(x,y) => x.distance.CompareTo(y.distance));  
    hit = hitArray.First(); 
    Debug.Log("Hit return: " + hit.normal);  
    return true;
}

By sorting like this I'm getting a normal of (0,0,0) all the time, despite for-loop showing the real normal and a hitLength of just 1.

Commenting sort out returns the same normal

[leaden ice]

why are you doing hitArray.First() instead of hitArray[0]?

Anyway you can't really do Array.Sort here

because the array is going to be longer than the actual number of hit results

You're better off using the List version of CapsuleCastNonAlloc here

[opal cargo]

Found I can do this 🙂

int hitLength = Physics.CapsuleCastNonAlloc( top, bottom, radius, dir, hitArray, dist, ~LayerMask.GetMask("Player"), QueryTriggerInteraction.Ignore);
if(hitLength > 0)
{
    for(int i=0; i < hitLength; i++)
    {
        Debug.Log("Hitlength:"+hitLength + " Hit"+i+": " + hitArray[i].normal + " name: " + hitArray[i].collider.name);
    }
    // Create comparer to allow comparison of RaycastHit Type
    Comparer<RaycastHit> comparer = Comparer<RaycastHit>.Create((x,y) => x.distance.CompareTo(y.distance));
    Array.Sort(hitArray,0, hitLength, comparer);
    // float closestDistNonAlloc = Enumerable.Min(hits.Select(hit => hit.distance)); 
    hit = hitArray.First(); 
    int index = 0;
    foreach(RaycastHit rchit in hitArray)
    {
        Debug.Log("Hitlength:"+hitLength + " Hit"+index+": " + rchit.normal );
        index++;
    } 
    return true;
}

[leaden ice]

and making sure the list is cleared first

that works too

[opal cargo]

And reset Array before

[leaden ice]

I didn't realize Sort has that overload

that's perfect for your use case

still

hitArray[0] will be faster than hitArray.First();

[opal cargo]

Sure, will change that 🙂

Took me a bit of crawling through Array.cs to find this but it's easy to use and I guess way faster than dealing with lists

[winged mortar]

Could do a lil bit of optimization by not creating a comparer every time the function is called

[cloud haven]

hello

[blazing void]

hi, I've locked my mouse in position with Cursor.lockState = CursorLockMode.Locked;, and then I gather user input through

float mouseX = Input.GetAxisRaw("Mouse X") * sensX;
float mouseY = Input.GetAxisRaw("Mouse Y") * sensY;

but, on my reset function I need the mouse to return back so both Input.GetAxisRaw("Mouse X") and Input.GetAxisRaw("Mouse Y") return 0. Is this possible?

[dusk apex]

Input.GetAxisRaw should only be the delta this frame.

The mouse should still be at center and not moving.

Maybe just set mouseX and mouseY to zero if you're wanting to default the values to zero in some function.

[blazing void]

sorry I’m new to unity and C#, what is a delta? and I use the input.getrawaxis in my update function. I’m making a new function that can reset the position of the player, I can easily move them but when I try to rotate them the function I have for turning just immediately puts them back to their previous position due to the Input.GetAxisRaw not resetting as well and so the game keeps them looking in that direction. I hope that makes sense, please correct me if I’m wrong

[rain minnow]

a delta is the change in value from the previous frame to the current frame . . .

[buoyant crane]

delta means change in, so in this context, the delta is the space you moved your mouse on the x and y between the previous frame to this frame

[blazing void]

ah okay that makes sense, thank you all

[buoyant crane]

I’m not really sure what your issue is though something to do with rotation?

[blazing void]

I will do my best to explain but if it’s unclear then don’t worry about trying to make sense of it

so my cursor is locked and the player can move the mouse left and right to turn left and right, and as it is just a first person character I just rotate the camera that is inside the players rigid body, and all works fine. When I try to teleport the player to a location it also works perfectly fine, but when I try to teleport them and rotate them so they’re facing a specific direction, then problems arise. I tried many methods to rotate the player, such as transform.eulerAngles, Quaternions, all that sort of stuff, and the player would rotate but then instantly be rotated back to their original direction. I presume this was because the program still thinks the mouse is in a place which links to a specific direction to face in, but I’m not sure. I’ve tried changing stuff but it hasn’t really worked, and so I came here for help

[buoyant crane]

how are you using mouseX?

like the rotation code

[blazing void]

that’s to look up and down

[buoyant crane]

could you send the code

[blazing void]

sure give me a few minute

should I use paste bin or just send it here

[buoyant crane]

ideally pastebin

[blazing void]

https://pastebin.com/JaG2ELWJ

^ that is my code for the generic turning of the camera

[buoyant crane]

all you need to do is set xRotation and yRotation to match the new euler angles you want

[blazing void]

wow, it was that simple

i kid you not i spent like 3 hours trying to figure out a solution 😂

[buoyant crane]

rotation can be tricky

[blazing void]

well, thank you very much for that!

[buoyant crane]

no problem

[night harness]

I can think of some janky ways to forward the calls but is there a decent way to get ontrigger function calls on behalf of another object?

[buoyant crane]

sure, just pass the data along
