[woeful leaf]

Because the inputs are seperate instances of the methods so therefore the vector not being combined, and thus that being the problem?

Because I need the combined vector and normalise that?

[fluid kettle]

yup

[woeful leaf]

How would I go about that though

With this code

[fluid kettle]

if you press W and A you want to sum the Vectors for W and A and not process them individually

[woeful leaf]

So I just have to rewrite most of it then

Hmm

[fluid kettle]

perhaps something like this?

public static Vector2 ProcessPlayerMovementToVector(Vector2 vector, in float multiplier, in Axis axis, in Polarity polarity)
    {
        vector.Normalize();
        
        vector = axis == Axis.X
        ? new Vector2((int)polarity * multiplier, vector.y)
        : new Vector2(vector.x, (int)polarity * multiplier);

        return vector;
    }

    private void MoveOnKeyPressed(KeyCode key, Axis axis, Polarity polarity, KeyCode key2 = null, Axis axis2 = null, Polarity polarity2 = null)
    {
        If(key2 ==null && axis2 ==null && polarity2 == null)
        {
            // Handle single Button Movement
            if (!Input.GetKey(key)) return;

            rb.AddForce(ProcessPlayerMovementToVector(rb.velocity, movementSpeed, axis, polarity));

            onMove?.Invoke(axis, polarity);
        
            print(rb.velocity.magnitude);
        }
        else
        {
            //Handle dual Button Movement
        }
    }

    private void UpdateMovement()
    {
        MoveOnKeyPressed(W, Axis.Y, Positive);
        MoveOnKeyPressed(A, Axis.X, Negative);
        MoveOnKeyPressed(S, Axis.Y, Negative);
        MoveOnKeyPressed(D, Axis.X, Positive);
        MoveOnKeyPressed(W, Axis.Y, Positive, A, Axis.X, Negative);
        MoveOnKeyPressed(W, Axis.Y, Positive, D, Axis.X, Positive);
        MoveOnKeyPressed(S, Axis.Y, Negative, A, Axis.X, Negative);
        MoveOnKeyPressed(S, Axis.Y, Negative, D, Axis.X, Positive);


        rb.velocity *= friction;
    }

that would be one way

Can't guarantee if it works, but that would be an idea for your given code

[terse venture]

How would i animate this in a 2D game? There is no horizontal or vertical movement, so im not sure how id get those variables to make my player animate.

[spark flower]

im experiencing some inconsistencies with the wait time, sometimes its like it waits more, sometimes less

usually its like the 1st wait is more then the next waits are less

[main shuttle]

How are you calling this? Because this should just wait 0.25 seconds and the next frame it should continue.

[swift falcon]

How come you aren't using Unity's Input system to manage the axis for you?

[woeful leaf]

I never went out of my way to learn the new input system. Initially didn't really need it since it had to be simple movement, but then I wanted a dash which suddenly makes things a lot more complicated and counts the old way I did it as obsolete, else the dash wouldn't work

[swift falcon]

ahh

[woeful leaf]

Yap, mistakes were made lmao

[woeful leaf]

Doesn't work

Still same effects

[swift falcon]

it shouldn't be too hard to adopt into your script honestly

[thin aurora]

Don't rely on Coroutines if you want an accurate timer

Rather create it in Update

[woeful leaf]

Albeit I don't use null since enums don't support null, so I just made a None for every enum

[woeful leaf]

I don't know I've not learnt the new inputsystem

[thin aurora]

This is an interval/timer I made yesterday that omits the accuracy problems of a coroutine
https://discordapp.com/channels/489222168727519232/497874004401586176/1060489281220657292

[woeful leaf]

Also a slight problem is that I don't have infinite time

I might just run with the "exploit" being there, if I can't fix it with similar to my concurrent code

[swift falcon]

It's entirely up to you, but I think you'd be surprised when you see how simple the input system is
https://docs.unity3d.com/ScriptReference/Input.GetAxis.html

[woeful leaf]

I think I'll run with the exploit for now, unless someone has a genius way of fixing it with the current code. I already spent an entire day on trying to fix it I honestly can't afford spending more time on it 😅

[swift falcon]

man Gladiator is typing an essay

void Update()
    {
        float xMove = Input.GetAxisRaw("Horizontal"); // d key changes value to 1, a key changes value to -1
        float zMove = Input.GetAxisRaw("Vertical"); // w key changes value to 1, s key changes value to -1

        rb.velocity = new Vector3(xMove, rb.velocity.y, zMove) * speed; // Creates velocity in direction of value equal to keypress (WASD). rb.velocity.y deals with falling + jumping by setting velocity to y. 


    }```

that's an example I found online, the axis's Horizontal and Vertical should already exist

[earnest gazelle]

What method do you favor to detect the type of a gameobject? For example, you keep a list of building gameobjects. They have different types, so, different components attached to.
Using enums? check a specific component existing in gameobjects?

public class BuildingController{
   private List<GameObject> _buildings;
   public IEnumerable<GameObject> GetAll(){return _buildings;}

   public IEnumerable<GameObject> GetAllByType(BuildingType type){
         return _buildings.Values.Select(building => building.GetComponent<BaseBuilding>().Type == type);
   }
   
   public IEnumerable<T> GetAll<T>(){
         return _buildings.Values.Select(building => building.GetComponent<T>()).Where(component => component != null);
   }
}

or if you would like to keep them in a dictionary, what is your key? enum type or type?
_buildings = new Dictionary<BuildingType,GameObject> BuildingType (Enum)
_buildings = new Dictionary<Type,GameObject>

or keep them separately. Define different classes (generic) for each?

public class BuildingController<T> where T:BaseBuilding{
   private List<T> _buildings;
   public IEnumerable<T> GetAll(){return _buildings;}
}

[thin aurora]

This will only work if all the types are the same

Just store it as a GameObject/Object/object

GetType() will give their type

[earnest gazelle]

What do you mean? only work if all the types are the same?

[thin aurora]

Pretty often applications just store as an object and then cast it back to the generic type. If this results in null the cast was invalid

[thin aurora]

You got multiple types, right?

[earnest gazelle]

new BuildingController<ResourceBuilding>().GetAll(); new BuildingController<ResidenceBuilding>().GetAll();

[thin aurora]

You can't get them all with the same generic type

[earnest gazelle]

?

They are different classes

[thin aurora]

Oh, you create one for every single type?

Why not store them all in a single controller?

[earnest gazelle]

BuildingController<ResourceBuilding> is a type, BuildingController<MilitaryBuiling> is another type

[earnest gazelle]

yes, as I mentioned, I can. Now, which one do you choose to get specific types?

public class BuildingController{
   private List<GameObject> _buildings;
   public IEnumerable<GameObject> GetAll(){return _buildings;}

   public IEnumerable<GameObject> GetAllByType(BuildingType type){
         return _buildings.Values.Select(building => building.GetComponent<BaseBuilding>().Type == type);
   }
   
   public IEnumerable<T> GetAllByType<T>(){
         return _buildings.Values.Select(building => building.GetComponent<T>()).Where(component => component != null);
   }
}

[thin aurora]

I'd just create a single manager that stores them all

Less confusing than having multiple. You can then abstract the complicating away by properly defining the method to get each type.

[earnest gazelle]

OK, BuildingController it is single

now, I want filter it, I think you did not get my question

[knotty sun]

dont cache the GameObject cache the component

[earnest gazelle]

Agree, you mean base component for buildings?

[knotty sun]

yes

List<BaseBuilding>

[earnest gazelle]

GameObject is evil, you access all components, completely true

I prefer to define a facade component keeping all component refs there

Now, how do you filter it by building type?

[knotty sun]

easy use _buildings[i].GetType().Equals(typeof(type I want));

[earnest gazelle]

enum type field inside or checking getcomponent or is checking on BaseBuilding

OK, thanks

[thin aurora]

It is probably better to just create a list of type Tuple<Type, BaseBuilding> instead of storing the whole gameobject

[thin aurora]

Because whilst also being sarcastic, this is also not a very good way to handle this problem

[mossy minnow]

why does Vector2.SmoothDamp need a ref for the velocity? and if i dont have a rigidbody on the object what should i put in there?

[tawny jewel]

can someone help me fix the script? ive been sitting on it for a while and im just getting more and more confused, the errors im getting is "target" does not exist in current context and "time" does not take the number of arguments: 1

using System.Collections.Generic;
using UnityEngine;

On how to post code

Syntax highlighting

[thin aurora]

Can you show this code from inside your editor?

[knotty sun]

target does not exist in the scope of time

[tawny jewel]

sure, but the issue is its in polish and i happened to also fail installing the language from unity

so yea sorry about that

[trim schooner]

Stop using GetComponent<T>() all the time for the same thing. Do it once and cache the result

[thin aurora]

1. You forgot to set the parameter in time
2. Even if you set it correctly, you use the parameter wrong in the coroutine

[tawny jewel]

thats what it looks like

[thin aurora]

And maybe do some lessons on basic c# because this is somethign you should understand

[earnest gazelle]

But I prefer generic BuildingController<T> where T:BaseBuilding, power of generic types. It is neat, clean

[thin aurora]

You can still do that

[tawny jewel]

i am doing a lot of those

[thin aurora]

typeof(T) should equal the type you store

[tawny jewel]

theres just a lot to learn

[thin aurora]

Maybe don't start immediatley with Unity but start smaller, like a regular console application

Nothing wrong with learning before you do the project

[tawny jewel]

im doing both at once honestly, doing lessons and then occasionally trying to work on my floppy bird in unity

[earnest gazelle]

You need to learn about scopes

In methods, you cannot access variables of another method defined.
You have to store it in a field

[tawny jewel]

sorry for even asking but can someone just tell me what lines of code i should add? i wonna just finish that part so i can go back to reading tutorials lmao

[thin aurora]

okay ill ask there i guess

[small citrus]

Hi, I have a question about the ScrollRect class
In the "OnScroll" method, the code is

            if (vertical && !horizontal)
            {
                if (Mathf.Abs(delta.x) > Mathf.Abs(delta.y))
                    delta.y = delta.x;
                delta.x = 0;
            }
            if (horizontal && !vertical)
            {
                if (Mathf.Abs(delta.y) > Mathf.Abs(delta.x))
                    delta.x = delta.y;
                delta.y = 0;
            }

Do you know why it is inverting axis if the value is higher than the original ?
This is causing the scrollrect to scroll vertical when I push the joystick left or right in XR.
I tried activating both axis to avoid this, but this is scrolling a little bit horizontal and it's not wanted.
Thanks

[woeful leaf]

This is the first time I've seen someone post code as a quote

Congrats on that, now read the #854851968446365696 and post it properly

[small citrus]

Sorry

[swift falcon]

Is there a way to open the Itunes library and import MP3 files during runtime?

[spark flower]

im trying to add a delay betwean item spawns, like you know how items get spawned from a chest 1 by 1

btw

why is this giving me null refrence?

[knotty sun]

And Line 47 of Macros is what?

[swift falcon]

OnGoldChange() by the looks of it

need to see that function

[knotty sun]

that aint gonna throw a null ref

[swift falcon]

Functions throwing a null ref :?

[spark flower]

thats what it says

[swift falcon]

[knotty sun]

ok, then your event is null

[spark flower]

like noone is calling it?

[swift falcon]

no its empty.

[knotty sun]

no like you have not filled it

[simple egret]

An event that has no subscribers will be null, yes

[spark flower]

yeah so noone is connected to it

[swift falcon]

bump

any of you fine lads ever worked with the itunes library and unity together by any chance?

[simple egret]

If it's possible to have no subscribers at some point, then you can use ?. (conditional access operator) to invoke the event:

OnGoldChange?.Invoke();

Will not invoke the event if it's null.

[spark flower]

i see thanks

i just made the registrations in awake instead of start and now it works

ill use that aswell

can someone help me?
this is what i want to do. i have a value Val = 100; and i want to spread this value across an array Array = 5 but i want each array slot to hold a random value from Val
so, Array[0] = 32; Array[1] = 42; Array[2] = 3; etc.

anyway

        int totalscrollvalue = Macros.CastlePower;
        int[] scrollvalue = new int[scrolls];
        int increment = 0;
        int scrolllength = scrollvalue.Length;
        print($"total scroll value: {totalscrollvalue}");
        for (int i = 0; i < scrolllength; i++) {
            increment = totalscrollvalue / (scrolllength - i);
            scrollvalue[i] = i >= (scrolllength - 1) ? increment : Random.Range((int)(increment * .3f), increment);
            totalscrollvalue -= scrollvalue[i];
            print($"scroll value {scrollvalue[i]}");
        }```

this is the solution that works for me now

[unreal temple]

var array = new int[5];
var val = 100;
for (var i = 0; i < array.Length; i++) {
  array[i] = Random.Range(0, val + 1);
}
Array.Sort(array);
for (var i = array.Length - 1; i > 0; i--) {
  array[i] -= array[i - 1];
}

You want the elements of array to sum to val right?

This will do taht

Conceptually it's placing 5 markers randomly on a number line from 0 to 100, and then measuring the distance between them.

So you'll get a completely random distribution

Could be 0,0,0,0,100

Could be 20,20,20,20,20

Actually that solution is imperfect because all the values might end up the same

And then it will fail

You can fix that though if it's the right approach

[simple egret]

My try at it, seems like it works fine

int sum = 100;
int elems = 5;
int[] arr = new int[elems];

for (int i = 0; i < elems - 1; i++)
{
    int n = Random.Range(0, sum);
    arr[i] = n;
    sum -= n;
}

arr[^1] = sum;

[woeful leaf]

How come this is not recognised

Whilst in Unity it is

[unreal temple]

Hover the red underlined identifier

[unreal temple]

Ah, your IDE isn't configured properly. Check #854851968446365696

[woeful leaf]

It is though

[unreal temple]

Is it VSCode?

[woeful leaf]

Unless it unconfigured itself again or smth

[woeful leaf]

No, VS

[woeful leaf]

The rest works fine

[unreal temple]

Not sure, but double check you have VS set as your external editor in preferences

And maybe regenerate project files

[woeful leaf]

It is I recently redid that because it unconfigured itself randomly

[unreal temple]

(not sure, I don't use VS)

[simple egret]

Yeah looks like a project file failure, where it doesn't include some files in the compilation

[unreal temple]

I'd def try regenerating project files and restarting VS though

[woeful leaf]

Where is that button again?

[unreal temple]

below this

[woeful leaf]

Ah

Nop

Still doesn't like it

[unreal temple]

this will be weird if it picks 100 first.

And also I think it has a bias towards the start of the array?

My probability skills are lacking so I could be wrong

[woeful leaf]

Regenerated, rebooted both Unity and VS

Still the same

[unreal temple]

that's annoying

Maybe you could try closing unity, deleting Library/ScriptAssemblies and reopening the project?

I'm not sure if that will help

But sometimes will fix weirdness like this

Worth a shot

[woeful leaf]

I really don't know how it's this broken I didn't do much

[simple egret]

Yeah it has a greater range towards the first elements, so it's more likely it'll pick a high number first. Gonna run some stats on it

[woeful leaf]

So everything in here?

[unreal temple]

I think my approach is pretty much correct wrt distribution, it just needs to make sure that the same value isn't picked twice, which I know how to do but since @spark flower hasn't replied I'm not going to bother writing it out.

[unreal temple]

yeah

Unity will regenerate it

It's safe to delete anything in library.

just trash the whole folder

[woeful leaf]

I deleted everything in the folder

[unreal temple]

sweet

[woeful leaf]

Is that not sufficient?

[unreal temple]

That's sufficient, yeah.

[woeful leaf]

Ah

[unreal temple]

Now reopen

And reopen VS after I guess

I don't really think this will fix your issue, but it's worth a shot

[woeful leaf]

Nop

Still dead

[unreal temple]

Where is the namespace coming from?

A DLL?

[woeful leaf]

Package

So somehow my IDE is not reading my packages properly

unlink the link I'll just paste it in the browser

Unless the bot picks that up too

[unreal temple]

Can you adjust which files get a generated csproj?

[sleek bough]

Make sure you didn't create a class with the same name yourself. Some of the autoprompts in VS could've done it

[unreal temple]

That's an option for VSCode

[unreal temple]

should still cause an error in Unity

[spark flower]

thats basicly how i did it aswell

[trim schooner]

There's a refresh connection button somewhere in VS, which will refresh the solution

[unreal temple]

yep, same issue in yours.

Only in reverse

Yours will bias towards 100

[simple egret]

Yeah it has a high bias towards the start of the array

[woeful leaf]

I do not have a namespace called Ransom nor the classes TimerActions nor So_TimerManager
The closest namespace I've is CustomTimer

[simple egret]

Sums for 15k picks: { 741386, 371801, 185540, 92761, 108512 }

[woeful leaf]

Also if this were the case then this'd give an error in Unity as well, no?

[woeful leaf]

(I didn't see this, whoops)

[muted idol]

guys I want to find an animation clip by keyword in a list of animation clips enumerated from the animator. so I did this
_animator.runtimeAnimatorController.animationClips.Find((anim) => anim.name == "asereje");
the animation clip that has similar name is there but it returns null. did I do something wrong?

[woeful leaf]

You mean this?

[unreal temple]

this should be right:
@spark flower

var array = new int[5];
var val = 100;
for (var i = 0; i < array.Length; i++) {
  var value = Random.Range(0, val + 1 - i);
  for (var j = 0; j < i; j++) {
    if (value >= array[j]) value++;
  }
  array[i] = value;
}
Array.Sort(array);
for (var i = array.Length - 1; i > 0; i--) {
  array[i] -= array[i - 1];
}

I haven't run it.

But maybe you can plug this into your test @simple egret

[woeful leaf]

This?

Afaik I never touched these checkboxes

[unreal temple]

Yeah, try checking git packages maybe?

[woeful leaf]

Yeah I was thinking of that, lemme check

[unreal temple]

@simple egret I just fixed a bug

in that code

mb

woulda been all zeroes

[trim schooner]

nope, because I saind in VS. This button is in Unity.

[woeful leaf]

Ah right

[woeful leaf]

I fixed it though, turns out this is the culprit - which is weird since it used to work

But then Ig it decided to stop working and I've to manually check that box

[unreal temple]

Well, it should work either way tbh. But this just forces it to create a csproj for that library.

Probably working around some obscure bug

in the visual studio package

You should also check if you can update the vs package in your package manager

[simple egret]

Distribution looks good, though sum never reaches 100 :/

[unreal temple]

99?

[simple egret]

I got one 99, but it's mostly random

[unreal temple]

oh darn

Well, there's some bug

That's what you get when you code directly into discord I guess

[unreal temple]

oh wait of course

The final sohuldn't be random.

[woeful leaf]

Ah that might be it

Lemme see if I can break it again

Then see if installing that update will fix it

[unreal temple]

var array = new int[5];
var val = 100;

// Pick random values in range [0, val].
for (var i = 0; i < array.Length - 1; i++) {
  // Select any value in range, subtracting the number of previously selected
  // values (as they are excluded).
  var value = Random.Range(0, val - i);

  // For every previously selected value exceeded, increment by one to prevent
  // collisions.
  for (var j = 0; j < i; j++) {
    if (value >= array[j]) value++;
  }

  // Store the adjusted value.
  array[i] = value;
}

// Set final value to max.
array[^1] = val;

// Now order values correctly.
Array.Sort(array);

// Measure the "distance" between each value and the one before it.
for (var i = array.Length - 1; i > 0; i--) {
  array[i] -= array[i - 1];
}

lol most ridiculous debugging loop

[woeful leaf]

I can't seem to re-break it, so I guess we'll never know

[unreal temple]

Glorious

The important thing is that you don't need to think about it for some indeterminate amount of time

[woeful leaf]

And then forget how I solved it previously and be stuck with the same problem eventually again

[woeful leaf]

If I untick the box, and regenerate the project files, does it remove the old ones for the ones that are unticked?

[vague slate]

type.GetMethods(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);
Is there a way to obtain methods including inherited ones?

[simple egret]

Perfect 👍

[unreal temple]

booya

[unreal temple]

@spark flower you seeing this shit?

I stayed up past my bed time for you

and the dream of a perfect distribution

[ebon fern]

Need Help Building Upon Dialogue System

[spark flower]

didnt quite get it

[unreal temple]

well, it solves your problem.

Basically what it does it repeatedly picks a random point in range, excluding points that have already been selected

Then it takes the difference between them to get the final values

For example if val is 10, it will pick a random number between 0 and 9

[knotty sun]

This code is completely insane

[unreal temple]

It's the simplest way I could think of to solve the problem 🤷

Very similar to how I do weighted probability

[knotty sun]

var value = Random.Range(array[i], val - i);

[unreal temple]

this approach was already discussed above

[woeful leaf]

Yup it's absolutely unbreakable

[unreal temple]

It will have a biased distribution
#archived-code-general message

[woeful leaf]

I removed the csproj files it generated for the package

But it still works

[sweet current]

BindingFlags.FlattenHierarchy ( https://learn.microsoft.com/de-de/dotnet/api/system.reflection.bindingflags?view=netstandard-2.1 )
Make sure to check compiling with IL2CPP if you intend to use that. Not all reflections work with that.

[unreal temple]

I reckon something was busted (caching issue somewhere) and now you've blasted it away through the change.

[woeful leaf]

What kind of sorcery is this, that it only needed to be generated once, and then just can be disposed again after

[knotty sun]

no more so than this

 for (var j = 0; j < i; j++) {
    if (value >= array[j]) value++;
  }

[unreal temple]

Perhaps the csproj wasn't properly regenerated when you hit the button

[woeful leaf]

I guess, it's pure sorcery though kek

[spark flower]

the name Array doesnt exist in current context it says

[unreal temple]

using System

[unreal temple]

Then explain the results
#archived-code-general message

[woeful leaf]

I don't think so - something is just off, anyway I'll just update the package for VS as well since rebreaking is not an option apparantly :p, thanks for the help

[unreal temple]

no probs, glad I chanced upon a solution

[vague slate]

nah, that's not what I look for, but dw I jsut made a recursion with BaseType

[unreal temple]

The way this works is not super obvious, but it's the same as creating a list of all possible values and then removing the ones you've already selected from it.

[spark flower]

you havent even tested this code

[unreal temple]

Me?

SPR did

[knotty sun]

but that is not what you are doing

[unreal temple]

Yes it is

That is exactly what this is doing

[knotty sun]

no, you are removing any value less than one already selected

[unreal temple]

You're simply mistaken

What can I say?

It's shifting the selection forward to skip the values that have already been selected.

[spark flower]

i dont see how this code is useful it has 3 loops while in my code it has just one

[woeful leaf]

Well the new one version kinda includes regenerations, but we'll never know if it'd have fixed it :P (I had the bottom one before this, also you're welcome for me inverting the colors kek)

[hollow stone]

My initial thought would be something like this. But it surely has some flaws ^^
I liked your way of thinking with the distributing with cuts @unreal temple , but dislike the sorting : )

var totalBuckets = 10;
var totalValue = 100;
var totalTokens = 0;
var buckets = new list<int>();

for totalBuckets
    var tokens = roll(0, totalValue + 1);
    totalTokens += tokens;
    buckets.Add(tokens);


var finalValues = new list<int>();
foreach bucket
    var valuePerc = bucket / totalTokens;
    var value = Round(valuePerc * totalValue);
    finalValues.Add(value);

[woeful leaf]

Yeah thanks for that :p

[woeful leaf]

var intensifies

[unreal temple]

Number of loops is not the same as usefulness

[spark flower]

@unreal temple i think your just overcomplicating this thing

well i need to do this 3 times

3x3=9 loops in one frame

for no reason

and i will add more items

[unreal temple]

it's not for no reason, it's to create an even distribution :-P

[spark flower]

so lets say i get to 20 items x 3 loops

60 loops

its not modifiable

[unreal temple]

What isn't?

[spark flower]

60 loops vs 20 loops

which one is better?

in one frame

[unreal temple]

The one that gives the correct result.

What is this line of reasoning

[spark flower]

optimisation kind

the 20 loops one gives correct resaults aswell

and is modifiable easily

[unreal temple]

Which code is better:

int Sum(int[] array) {
  return 0;
}

int Sum(int[] array) {
  var result = 0;
  foreach (var e in array) result += e;
  return result;
}

First has zero loops

Second has one loop

1 > 0

[rain minnow]

That's not an optimization. The results are different based on your one loop verse their 3 loops. The issue here is accuracy . . .

[unreal temple]

Therefore first is better?

[knotty sun]

imagine the generation sequence 9,8,8 you will end up with 9,8,9

[unreal temple]

That sequence is not possible because of this line: var value = random.Next(0, val - i);

[vague slate]

they do different thing, comparison is not correct

[spark flower]

accuracy is not the issue, its supposed to get random value for each index

[unreal temple]

exactly

[spark flower]

the one with less loops does the job

no need for 3 loops

[unreal temple]

then why are you talking to me?

[spark flower]

what accuracy are you talking about?

im talking to invader

[unreal temple]

invader is referring to the distribution bias in your/srp's solution

[spark flower]

what about it

[knotty sun]

100-0, 100-1, 100-2, yes it is

[spark flower]

unnececery complicating the code

just to force solve it through an idea

[unreal temple]

Ah. you're right. It needs to be sorted on each iteration to work correctly.

So that the result would be 9,8,10

[knotty sun]

exactly

[unreal temple]

Good catch

I'm not sure if that makes it insane though.

[knotty sun]

you need to store highest number so far

[unreal temple]

Perhaps there's a simpler way to structure it.

[knotty sun]

and if you are going to do that you might as well just restrict your random.range

[unreal temple]

your suggestion:

var value = Random.Range(array[i], val - i);

consider what happens if the first value picked is 100

Assuming that's meant to be array[i - 1]

I actually am not sure what you're going for here

array[i] is always 0 in the fresh array

[knotty sun]

so start val at val - Array.Length and increase it

indeed i-1

[unreal temple]

So your first value is in range [5, 100]?

[knotty sun]

no, val = 100
array.length = 5
range = 0 to 95
generated = 15
range = 16 to 96

etc

https://github.com/Unity-Technologies/com.unity.multiplayer.samples.coop.git?path=/Packages/com.unity.multiplayer.samples.coop#main

I've tried restarting unity and nothings changed

[unreal temple]

You need to add git to your Path system variable

I have a guide for this for my team

[cinder kindle]

How do I do it?

[unreal temple]

oh actually it's not that hard

Just install git-scm

It should do it for you

[knotty sun]

I have a higher/lower card game that works on exactly this principle

[unreal temple]

Basically you just need to install git

[unreal temple]

well your solution is better. I bastardised my solution for weighted select

wrong code

Hm. Can't remember where I used this pattern, but somewhere at some time that made more sense.

[unreal temple]

You on windows? Install this https://git-scm.com/download/win

[cinder kindle]

i did

[unreal temple]

Make sure you check the option to add to Path

If there is one

Otherwise just select all the recommended options

there are a lot of installation options

[cinder kindle]

yeah

[unreal temple]

You'll need to completely restart unity hub after installed installed @cinder kindle

[cinder kindle]

do i need to launch it

[unreal temple]

Not just unity

[cinder kindle]

task manager style?

[unreal temple]

No, unity runs it for you

It's just a program that unity is trying to run directly

It's a CLI application

Windows for some reason doesn't come with it

Unlike Linux/macOS and other *nix OSes

But make sure you fully exit unity hub and restart it or else it won't see the updated Path variable

[cinder kindle]

still not working

i task manager quit unity and unity hub

100 percent added it to path

[cinder kindle]

jesus thank you

[unreal temple]

nice

[spark stone]

So esentially I have a missile going up and I want it to be when it gets close to a circle (black whole kinda) it gets sucked slughtly and and is being pulled by a graviational force, problem is I dont know how to rotate the missile towards the direction if being pulled if that makes sense. heres my current code ```cs
public float suckingForce = 10; // The strength of the black hole's sucking force
public float rotationSpeed = 1; // The speed at which the ship rotates around the black hole

public float radius = 5f;

Vector2 pullForce;

void FixedUpdate()
{
    // Find all objects within the black hole's radius
    Collider2D[] colliders = Physics2D.OverlapCircleAll(transform.position, radius);
    foreach (Collider2D collider in colliders)
    {
        if (collider.GetComponent<Rigidbody2D>())
        {
            float distanceToPlayer = Vector2.Distance(collider.transform.position, transform.position);

            Rigidbody2D rb = collider.GetComponent<Rigidbody2D>();
            pullForce = (transform.position - collider.transform.position).normalized / distanceToPlayer * suckingForce;
            rb.AddForce(pullForce, ForceMode2D.Force);
        }
    }
}```

[unreal temple]

You can use vector3.rotatetowards to move the forward direction towards the force

[spark stone]

this would work for 2d?

[tawny jewel]

can anyone recommend any good site/program to learn c#

[unreal temple]

I was just thinking about this more. This solution still gives you a bias towards the high end. On average your first pick will be in the middle, so say ~50, which means every additional number selection is going to be higher than that.

So your numbers will be more densely packed towards the higher end (on average)

It only solves the problem of collisions, but doesn't give an even distribution

Which may or may not matter

But it doesn't solve the same problem

Unless I'm misunderstanding

[knotty sun]

no, you are absolutely right, however there are algorithms to mitigate this

[unreal temple]

Right... Well calling mine 'insane' seems pretty silly when you could have just shown one of these other algorithms

[knotty sun]

that would have been too easy

[warped compass]

I'm having an issue where the collision for the attack is sometimes delayed. Both the enemy and sword have a rigidbody with continuous collision.

When both collide the enemy is supposed to react with an animation and a knockback force. Sometimes it happens immediately like its supposed to, other times it is delayed by like half a second.

It doesn't seem to have anything to do with performace, it happens regardless if its running at 50 fps or 200.

The attack hitbox enables via an animation event, and is not having any issues with enabling from what I've seen.

Here's all the code associated with the collisions:

(Weapon script)

    {
        if (other.CompareTag("boss") || other.CompareTag("enemy"))
        {
            hitbox.enabled = false;
        }
    }```

(Enemy script)
```    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("blade") && health > 0)
        {
            knockback();
            endattack();
            anim.SetBool("attack", false);
            anim.SetBool("running", false);
            anim.SetBool("hit", true);
            hitcount = hitcount + 1;
            anim.SetFloat("hitcount", hitcount);
            health = health - 40;
            attackdelay = attackdelaydefault;
            attacking = false;
        }
    }```
I have no idea what I've done wrong, I've never had this issue before.

Thanks.

int val = 100;
int[] vals = new int[vals.Length] { 0..val }
int length = 100;
...
loop {
int ix = Random.Range(0, length);
int value = vals[is];
length--;
vals[ix] = vals[length];
vals[length] = value;
}

[unreal temple]

Try that for a maximum of 1000000

[knotty sun]

np

[knotty sun]

but you are moving the goal posts, your original code had val at 100

[unreal temple]

It's irrelevant really. The allocation of 100 is needless

You don't know how many times it will be called

[knotty sun]

read the code, it doesn't matter

[unreal temple]

I have, it's the same as mine without the optimisation

And without the bug you found

Which is fixable

[knotty sun]

it's not the same as your's at all and it addresses your question about distribution

[unreal temple]

It's the same algorithm, different implementation.

Picking from a set that excludes the previously selected numbers

[knotty sun]

except mine works and your's doesnt

[woeful leaf]

This is what I had to convert it to be since null doesn't work for enums https://gdl.space/qurimekiwi.cs

Any thoughts on Unity's GitHub integration via Unity directly https://unity.github.com/ vs Git command line via WSL? I'm used to command line at work, but curious if the Unity GitHub direct integration in Unity helps with some of the Unity aspects that I may not be aware of.

[unreal temple]

Just need to move the call to sort. Yours is pseudocode so it also doesn't "work"

[unreal temple]

I'd avoid it unless you really need the LFS lock feature for artists

I don't want to have to open unity to use git

Use a GUI like git-fork or sourcetree

GitHub desktop is also an option

[tough osprey]

Any reason you'd recommend the GUI vs command line? Personal preference or is it better for Unity aspects like Large Files?

[unreal temple]

Git CLI is notoriously hard to learn and confusing. There are other reasons too but the list is so long I don't know where to start

Very few people use git CLI directly

Just like beardy old Unix guys

And web dev hipsters who think it's cool

Being able to see your history is extremely valuable

[tough osprey]

hahaha, I use it exclusively at work, didn't realize that put me in a box 😛

[unreal temple]

I used to as well

Staging individual lines is a pain in cli, as is cherry pick etc

[woeful leaf]

Honestly I myself just use GitHub Desktop - it can be a bit limited in features, but if you really need to do something more advanced, you can always open up Git Bash to do something extra

(A git reset par example)

[unreal temple]

You should try git fork

[woeful leaf]

I think sourcetree has more features

[unreal temple]

It's very good

[woeful leaf]

Hm, I like the simplicity of GitHub Desktop

[unreal temple]

It's free if you don't mind the nag message

Then don't!

[woeful leaf]

Haven't tried git fork though

[tough osprey]

Well since this is a side project where I'm learning new things ... it's a good opportunity to try a new way to Git

[unreal temple]

It's just a layer over cli

Cli knowledge is great still for automation

Build and release pipelines

Etc

[sonic harness]

They need context on the error, like where did it happen, and what did you do to get it.

No context, so can't help

[agile brook]

Hi, I want to make an AI navigation system based on waypoints. The AI spawns at one corner of the map and has to try to get to a target point, which is itself linked to a waypoint. Between the starting waypoint and the waypoint linked to the target, I want to search all the waypoint connections to figure out the path to take from start to end. Does anyone know the best way to begin implementing this?

[hollow stone]

It's weird that you say that you want to search all the connections? Usually you only want to search as few as possible for computation sake but still get the correct result. The most commonly used navigation algorithm is A* which is probably what you want anyway.

BetterClickerPrice = Mathf.Round(BetterClickerPrice * 1.1f); whats the issue here, new to mathf libary

Error    CS0266    Cannot implicitly convert type 'float' to 'int'. An explicit conversion exists (are you missing a cast?)

thats the error

[prime sinew]

Mathf.Round takes in what value type

hover over it and see

[sterile relic]

float

[leaden solstice]

The return value of Round is still float

[prime sinew]

oh, hold on

what type is BetterClickerPrice

[sterile relic]

int

[prime sinew]

okay

Mathf.Round gives you a float, you're trying to assign it to an int

[sterile relic]

so i need a int return from round

[leaden solstice]

Use RoundToInt

[prime sinew]

that's the issue

[leaden solstice]

It's just same as (int)Mathf.Round but in prettier form

[sterile relic]

gotcha thank you

ah i wasnt aware it was an enum. Yea sry for the trouble then >-> But if it works now everythings allright, no ^^

2022 something

[candid kiln]

Ok

[thick socket]

found the issue...guess I should have included more code 😭

like 3 lines above that I had an unfixed if statement

[agile brook]

I’ve never implemented A* before, but doesn’t it operate off distance to the target? I’m essentially trying to figure out a path between two waypoints, with the path being comprised of waypoints that have already been placed, and this means that the distance might not necessarily always decrease if the waypoint path winds around obstacles or something like that. I need this algorithm because many of the waypoints branch off and could be navigated multiple directions.

[mossy minnow]

hey everyone, so im trying to make a top-down movement controller, and i want to be able to control the friction of starting/stopping without affecting the max speed in any way.
right now im using:

        curVelDebug  = rbVel;```
but it seems that when i move the frictionAmount, it changes the max speed in strange ways
im just doing `rb.velocity = rbVel;` for actually setting the vel

[prime sinew]

please don't crosspost. stick to one channel

[mossy minnow]

sry

things get buried very easily in these chats i find u-u

[leaden solstice]

Yeah forum channel when 😄

[leaden solstice]

SmoothDamp 's velocity is not meant to be used by you

It's return value is position

[mossy minnow]

sry dont fully understand that

Heyo, so has anyone here used the strand hair physics solution?
If so any idea how to get the vertex data of the hair, im having no luck 😦

[mossy minnow]

so if i dont use the vel on the SmoothDamp how do i use it?

where does it return a position\

and what is that position

and how do i use it

[uncut vapor]

Any idea why a [SerializeField] private Image[] isn't showing in inspector?

the word private

Im 80% sure that needs to be deleted

😭

[uncut vapor]

I tried just without private, with public instead and it doesn't change nothing

[mellow sigil]

Do you have any errors in the console

[uncut vapor]

nope

[late lion]

Could you post what using statements you have at the top of the file? You might be referencing the wrong Image type.

[uncut vapor]

Oh yeah you're right lmao

[mossy minnow]

what would the best way to spawn multiple enemy types? i want to be able to instantiate a new enemy with a random enum (Melee, Ranged, Bow, Bomber)

[orchid bane]

Made this little "extension" for Zenject https://github.com/Telov/Extenject
Any feedback?

[leaden solstice]

The return value. Like
current = Vector2.SmoothDamp(current, target, ref vel, ...)

[halcyon thorn]

I am having trouble with Physics.CapsuleCastNonAlloc(...). It always returns 0 collisions.
The two sphere gizmos you see are at the bottom and top positions I pass in, radius is the same direction is a non-zero vector.
No special layer mask. maxDistance is 2f.
The objects with colliders I am trying to check against are on the Default layer.

I do not understand what is wrong here.

[rain minnow]

you can use SOs. make an SO class with a field to hold the (enemy) prefab and create an SO asset for each enemy prefab in your project. now place those SO assets in a list and randomly select an index from the list. use the index to access the SO asset (from the list). finally, access the field from the SO class to instantiate the prefab . . .

[mossy minnow]

then what do i put in the ref vel?

[leaden solstice]

It's just a variable that controlled by SmoothDamp

You don't need to modify or set anything for it, just keep the value as member field

[rain minnow]

create a gizmo to visually see the distance and direction of the cast . . .

[woeful leaf]

No it didn't actually work heh

As far as I could tell, it didn't change anything

[zinc parrot]

Hey so when I have combined meshes due to them being Static, what data to I have access to from there?

[halcyon thorn]

White is the original, green is the final

this is the ground it's intersecting

        var bottom = CurrentState.Position + Vector3.up * radius;
        var top = CurrentState.Position + Vector3.up * (height - radius);
        var direction = _desiredPosition - CurrentState.Position;

        // Check for possible collisions
        var collisions = Physics.CapsuleCastNonAlloc(bottom, top, radius, view.forward, hits, 2f);

        Gizmos.color = Color.white;
        Gizmos.DrawSphere(CurrentState.Position + Vector3.up * radius, radius);
        Gizmos.DrawSphere(CurrentState.Position + Vector3.up * (height - radius), radius);

        Gizmos.color = Color.green;
        Gizmos.DrawSphere(CurrentState.Position + Vector3.up * radius + view.forward * 2f, radius);
        Gizmos.DrawSphere(CurrentState.Position + Vector3.up * (height - radius) + view.forward * 2f, radius);

first is the collision code, the second is the gizmos

collisions always returns 0

I think I figured it out. CapsuleCast works, CapsuleCastNonAlloc does not. It seems to be an issue with the fact that hits was not instantiated

[rain minnow]

is hits your array? if so, you need to initialize it when a set length. the cast will populate the array with colliders until it fills the array . . .

i don't see where you initialize hits at all in your code. better to use this method as it doesn't generate garbage . . .

[halcyon thorn]

Yeah, that was the issue. I did not instantiate the hits array with anything, it was null. Figured it would throw an error but I guess not

[halcyon thorn]

Another issue now - hits[0].point returns (0,0,0)

even though hits[0].collider.gameObject.name returns the name of the object correctly

does it get cleared or something when accessed?

[rain minnow]

nope . . .

[halcyon thorn]

Debug.Log($"Hitting {hits[0].collider.gameObject.name}, {CurrentState.Position}, {hits[0].point}");
Debug.DrawLine(CurrentState.Position, hits[0].point, Color.green, 1f);

Hitting Floor, (-29.63, -0.04, 4.50), (0.00, 0.00, 0.00) every single time

hits[0].point is always the zero vector...

[rain minnow]

that is weird. is that the only hit or are there more?

[halcyon thorn]

the first hit is always the character itself, which I ignore

unless it hits something else

always returning zero vector for all hits

[rain minnow]

this looks like the character for all of your hits . . .

[halcyon thorn]

oops, you are correct. there is another one with the floor as well one sec

[rain minnow]

make sure you check if the collider from the RaycastHit is not null before attempting to access it . . .

[rain minnow]

and ensure the length of the buffer (array) can store the amount of colliders needed . . .

[halcyon thorn]

        Debug.Log("=============================");
        foreach (var hit in hits)
        {
            if (hit.collider == null) continue;
            Debug.Log($"Name: {hit.collider.name}, Point: {hit.point}");
        }
        Debug.Log("=============================");```

hits = new RaycastHit[5]; before every cast

[rain minnow]

you only need to initialize it once, not every time . . .

move the cast position and check if hit.point changes . . .

[halcyon thorn]

won't it retain all the old raycast hits?

[rain minnow]

based on where it's at, it is hitting the floor at 0, 0, 0 world position . . .

[halcyon thorn]

the position of the character is nowhere near

[rain minnow]

can't remember but i believe so. you can clear or empty the list instead . . .

[halcyon thorn]

it's not a list, so I just make a new one for now. I am just trying to get the thing to work first

oh wtf... it does it correctly but only once

Position: (-30.00, 0.00, 0.00), Name: Floor, Point: (-30.00, 0.00, 0.00)

then every subsequent time it's Position: (-29.98, -0.05, 0.11), Name: Floor, Point: (0.00, 0.00, 0.00)

okay so it seems that if the collider already intersects the capsule cast, it will say that the point is 0,0,0

that makes no fucking sense to me

[rain minnow]

yes, that is normal . . .

[halcyon thorn]

why is this considered normal?

[rain minnow]

any colliders that overlap at the start of the cast have their normal set opposite of the direction, their distance set to zero and the point returned set to a zero vector . . .

[halcyon thorn]

that seems like something that should be mentioned in the docs or something

I'm not a mathematician and I can't inspect the source code to figure that out

[rain minnow]

it is in the docs, the problem is where. all the information is from the regular CapsuleCastAll, (for some weird reason) details are implied when using the NonAlloc version as the only difference is creating the buffer array yourself to save from garbage collection . . .

[halcyon thorn]

either way, it shouldn't return the zero vector if the comment states that RaycastHit.point will return the world space impact point where the ray hit the collider

either that or the comment should be more clear

ugh that is so frustrating, thanks for the help

[rain minnow]

yes, but that is only if the collider does not already overlap the capsule at the start of the cast/sweep . . .

[halcyon thorn]

yeah, I mean that it should be clear in the comment there

[rain minnow]

it doesn't cast bc a collider is already occurring . . .

[rain minnow]

this scenario is not true for every cast method. they can't use that description for RaycastHit.point since it doesn't apply 100% of the time, only for the cast method used as each of them are different . . .

[halcyon thorn]

oof

[spiral geyser]

Is there anyway to change SetActive of a gameobject while inside of a script in Unity?

like referencing a gameobject then setting something inside it to on?

https://docs.unity3d.com/ScriptReference/GameObject.SetActive.html

Oh I am stupid

[knotty sun]

yes, use SetActive

[spiral geyser]

lol I am stupid sorry

[uncut vapor]

I wanna make a grid made of lines
And I need to calculate the coords of each of the lines
I have a var for which line in the row is it, in which row is it, how big each line is, how much lines is there in a row and how much rows is there but I been trying to get the math right for last hour
Anyone got the solution?

[marble halo]

Anyone know how to make a skinned mesh renderer follow a ragdoll?

because if it doesnt the ragdoll will often turn invisible when looking at it

[potent sleet]

not really a code question.
you need colliders on each bone of the avatar

[marble halo]

I do, also where would be a better place to ask?

the problem is the cube doesnt move with the ragdoll

wait does that include the root bone?

[potent sleet]

#💻┃unity-talk

[potent sleet]

why would it.. it's not parented to bone

[craggy nova]

Do I need to somehow put jump function (with rigidbody) in FixedUpdate if I am using the unity event in new input system?

I can't think how to do it

and tutorials don't seem to be doing so as well

[left narwhal]

seems all right

dont think it matters that much

[desert shard]

input to action is irrelevent for this. depends on the method of jumping.

[tulip silo]

i have a raycast that i am using from the camera to detect items along with looking at them, this works, but the raycast goes through objects with other tags from the one i'm targeting, also some of the items won't turn off when i look away from them, or they will turn off as i'm moving and looking at them. if anyone knows what to do about this part then please let me know

[potent sleet]

sounds like the colliders aren't setup properly or your logic is flawed, hard to know without much context / code

[tulip silo]

the colliders are set up properly, and here's the code for the "logic" part of it

the done part is just from another trigger to check if the player is in the store or not, and seen is for the box collider being within the camera's vision at all

[shut ridge]

when it comes to netcode, is there a way to identify individual players

like some sort of playerid

[pearl radish]

Clients all have a client id

[shut ridge]

how do i fetch it?

[pearl radish]

You should consider consulting the documentation for whichever networking solution you're using

[shut ridge]

netcode

[pearl radish]

I said you should, not I'm going to

[shut ridge]

aight bet

[spiral geyser]

I am getting 3 separate NullReferenceException: Object reference not set to an instance of an object errors in my Movement code and I honestly can't figure out why?

[shut ridge]

interesting

paste your code

or send screenshots

[spiral geyser]

I put it in a pastebin

https://pastebin.com/J1dg7Len

its 209 lines tho so thats why

It says the three different errors are at

[shut ridge]

pastebin is giving me errors

[spiral geyser]

lines 72, 104, 187

[shut ridge]

could you paste it fr with the discord formatting system?

or dm me it

that would be faster

[spiral geyser]

okay I just didn't want to clutter things up

[shut ridge]

thats sensible

i suggest dms in that case

[spiral geyser]

I dmed it to you

Okay fixed

Found the issue: I'm an idiot and didn't put in the right script in the editor

[viscid kite]

is there any performance difference between Transform.Find("") and Transform.GetChild()?

[uncut vapor]

Is it possible to change the highlited, pressed ect. tints in a button through script?

[rain minnow]

Yes, greatly. Did you check the unity docs?

[rain minnow]

Yep, that's doable . . .

[uncut vapor]

Uh
How
Cuz just button.colors.pressedColor = ... shows an error (can'y modify the value cuz it's not a variable)

[viscid kite]

i guess which doc? is it their respective page or something else?

from what i say, don't use string based searches...but that wasn't from a unity doc so i'm unsure if that's the answer i should've reached

[shut ridge]

its less docs and more just how they work

getchild is inherently faster

bc it is far more efficient compared to find

[rain minnow]

ColorBlock is a struct. You have to store it in a temp variable, change the colors and assign it back . . .

[uncut vapor]

aand what does assign it back mean

[shut ridge]

finding by name is way slower than finding by index of children

[viscid kite]

got it

[rain minnow]

From their descriptions in the unity docs ` Find searches the entire scene(s) and should not be used frequently for performance reasons

Transform.Find searches for a child GameObject of the transform, not through entire scene (as stated in both docs) . . .

[rain minnow]

Huh? Have you used a struct before? When you assign the temp variable back to the property. This is common . . .

[rain minnow]

It's not less about the docs, the answer is in the docs, and Transform.Find searches with a string, not an index. The more efficient bc it only searches a GameObject's children, not the entire scene . . .

[shut ridge]

i meant that the docs don't affect the functionality, they communicate it

[rain minnow]

That would be confusing bc they were asking about which docs to look at and read . . .

[shut ridge]

ah i see

my apologies

[viscid kite]

ah yeah whoops meant to say use transform.Find("") so like within scope of the child of the object in question

but still yeah noted

[dull magnet]

Hi, I've built a simple script to rotate a camera. This works fine as long as I move the mouse slowly. If I move it too fast, the camera rotation will stutter.

if (mouse.rightButton.wasPressedThisFrame)
{
    rotateStartPosition = mousePosition;
}
if (mouse.rightButton.isPressed)
{
    rotateCurrentPosition = mousePosition;

    Vector3 difference = rotateStartPosition - rotateCurrentPosition;

    rotateStartPosition = rotateCurrentPosition;
    newRotation *= Quaternion.Euler(Vector3.up * (-difference.x));
}

I'm assuming this has to do with difference being too big and skipping a full circle, but clamping it didn't really help. Making it slower with something like difference.x *= 0.5f did mitigate it a bit, but I would hope I could fix it without making it slower. Any advice?

[limpid spire]

I made a new project, and when i tried to create a new workspace with plastic SCM i get this error:
"No connection could be made because the target machine actively refused it."
does anyone know how to fix this?

[charred charm]

Does anyone know why this is happening? Can't build all of a sudden

[unreal temple]

Try closing unity, deleting Library/ScriptAssemblies and reopening project

If that fails step back through your commit history until you can find a working commit.

And look at the diff

See what could be relevant

I'd say it's just cache corruption though

if it's "all of a sudden"

[charred charm]

That didn't help, I suppose. That being said, I can play in the Editor just fine, does that give any more information?

[unreal temple]

I haven't seen that error before. You could try nuking the Bee folder too and see if there's some issue there

[charred charm]

I tried that, still didn't work unfortunately. And I undid some changes I did and went back to a state where I had a successful build but I still have the same error

It's not a big enough project to go through my commit history since I had only very few changes since last commit

My thought process is that if it works when I click play in the editor then it shouldn't be any of my few scripts, right?

[bronze whale]

are scriptable objects a good way to save player progress?

[gaunt garden]

I wouldn't say they are particularly suited for it, since for a save state you generally need to write a file to disk

ScriptableObjects don't really make that any easier

[bronze whale]

Is there a built in solution for this?

[gaunt garden]

I guess the closest would be PlayerPrefs, but that only works for very simple cases

It depends a lot on the project

[bronze whale]

can serialization be used to save progress?

Or is that only for saving editor changes

[gaunt garden]

It is usually involved, serialization is just the transformation of an in memory data structure to a stream of something that can be written to a file

How that is achieved is up to you

I can give you a simple example if you want

[bronze whale]

No thanks

I think a json or something would be enough then

[gaunt garden]

Yes, JSON is a common format for save files

[bronze whale]

Cool, thank you

[worthy galleon]

BoxCast doesnt seem to be very consistent in returning true if its hitting something... am I giving it the wrong information here?

hitDetect = Physics.BoxCast(transform.position, transform.localScale, destination, out hitInfo, transform.localRotation, lengthCast);

by my understanding this should shoot out a box with the same size as our player (which is a 0.85x1.275x0.85 box), from our player's position, with our player's rotation (none), and it should go from the center of our player out in the direction 'destination' a total distance of 'lengthCast'

im successfully using the information gathered from the BoxCast when it works, the problem is it doesnt seem to actually be able to hit stuff consistently

[neat lagoon]

https://github.com/nomnomab/RaycastVisualization I will plug this package

good for debugging stuff like this 👍

[dusk apex]

You could attempt to visualize the cast using assets such as the above or this https://github.com/vertxxyz/Vertx.Debugging

[worthy galleon]

surely i can use BoxCast for collision detection in 3d right?

just wanna make sure im not tryin to use the wrong tools

[neat lagoon]

that's what it's for, yes

[worthy galleon]

ok thank god

as long as its a user error im ok LOL

ty for the tools :3

[void basalt]

I have an issue. I have an abstract class that inherits from mono and uses unity's Start() to do important stuff. If I create a new class and make it inherit from my abstract, it automatically puts the default Start() function inside and overrides the abstract start

and screws things up

is there a different way that I can get a callback on object initialization? Can't use constructor because of monobehaviour and RuntimeInitializeOnLoadMethod doesn't work on non static methods

[leaden solstice]

Make your Start as protected virtual

override it from child class then call base.Start()

[void basalt]

This doesn't fix the original problem of Start becoming hidden in the child class and automatically overriding the functionality of the abstract

It's more of just trying to idiot proof it

Since it pretty much breaks the entire framework

Perhaps I could just use a static class to loop through gameobjects and do my own callbacks at the start

I can't find any other solution

[leaden solstice]

If you have protected method in parent C# will make warning so

Or don't make user inherit from your class at all and use composition instead

[void basalt]

hmm

[wild nebula]

I'm running into a strange rotation issue

This is a debug for hlsl shader, I'm trying to do it in C# first.

    [ExecuteInEditMode]
    public class ToaTest : MonoBehaviour
    {
        public Transform Target;

        float TOA(float opposite, float adjacent)
        {
            return math.degrees(math.atan(opposite / adjacent));
        }

        void Update()
        {
            if (!Target) return;

            Vector3 deltaPos = transform.position - Target.position;
            float angleX = TOA(deltaPos.y, deltaPos.z);
            float angleY = TOA(deltaPos.x, deltaPos.z);

            Vector3 finalAngle = new Vector3(-angleX, angleY, 0);

            //Debug.Log(finalAngle);

            transform.rotation = Quaternion.Euler(finalAngle);
        }
    }

When the angle values are close to 0, it just rotates strangely

I can't use lookat because I need to clamp the euler angles to have a min/max rotation.

Please help :c

[leaden solstice]

https://github.com/cathei/RotationMath/blob/main/Packages/com.cathei.rotationmath/Runtime/RotationMath.cs#L104
This may help?

Your pitch calculation may be wrong to use atan

[wild nebula]

So use atan2 instead?

[leaden solstice]

Nah did you see Pitch function

[wild nebula]

        public static float Pitch(Vector3 forward)
        {
            return -MathF.Asin(forward.y) * Rad2Deg;
        }

[leaden solstice]

Yes

[wild nebula]

Ok I'll give it a go

[leaden solstice]

Yaw for Y, Pitch for X in euler

[leaden solstice]

Oh and make sure you normalize forward

[wild nebula]

This is way better, it doesn't go crazy when any axis is close to 0

But its jittering right now

    [ExecuteInEditMode]
    public class ToaTest : MonoBehaviour
    {
        public Transform Target;

        private Vector3 Forward(Quaternion rotation)
        {
            float x2 = rotation.x * 2f;
            float y2 = rotation.y * 2f;
            float xx2 = rotation.x * x2;
            float yy2 = rotation.y * y2;
            float xz2 = rotation.z * x2;
            float yz2 = rotation.z * y2;
            float xw2 = rotation.w * x2;
            float yw2 = rotation.w * y2;

            return new Vector3(xz2 + yw2, yz2 - xw2, 1.0f - (xx2 + yy2));
        }

        private float Yaw(float opposite, float adjacent)
        {
            return math.degrees(math.atan(opposite / adjacent));
        }

        private float Pitch(Vector3 forward)
        {
            return math.degrees(-math.asin(forward.y));
        }

        void Update()
        {
            if (!Target) return;

            Vector3 deltaPos = transform.position - Target.position;
            //float pitch = Pitch(Forward(math.normalize(transform.rotation)));
            float pitch = Pitch(Forward(transform.rotation));
            float yaw = Yaw(deltaPos.x, deltaPos.z);

            Vector3 finalAngle = new Vector3(-pitch, yaw, 0);

            Debug.Log(finalAngle);

            transform.rotation = Quaternion.Euler(finalAngle);
        }
    }

I commented the normalize because I think Forward(quat) is already normalized

Whoops my bad

I had -pitch

That's the whole problem

[leaden solstice]

Oh I mean you put forward as your direction

[wild nebula]

Swapped Vector3 finalAngle = new Vector3(-pitch, yaw, 0); with Vector3 finalAngle = new Vector3(pitch, yaw, 0); and its smooth :))

Thanks so much, it worked really well!

[leaden solstice]

deltaPos.Normalize();
float pitch = Pitch(deltaPos);

This way would be more correct

[wild nebula]

Oh ok

[leaden solstice]

And I think it should be target - position ? but idk your setup 😄

[wild nebula]

I am trying to make a billboard that can be clamped

[leaden solstice]

Oh sure

[wild nebula]

        void Update()
        {
            if (!Target) return;

            Vector3 deltaPos = Target.position - transform.position;
            deltaPos.Normalize();

            float pitch = Pitch(deltaPos);
            float yaw = Yaw(deltaPos.x, deltaPos.z);

            Vector3 finalAngle = new Vector3(pitch, yaw, 0);

            Debug.Log(finalAngle);

            transform.rotation = Quaternion.Euler(finalAngle);
        }

Swapped

I think there is still a problem when Z value is close to 0

Y rotation still jumps

[leaden solstice]

Oh yeah

Use atan2

For Yaw

[leaden solstice]

Because if Z is 0 then you get NaN

[wild nebula]

It worked!

Ah I see

Thank you so much

I'll try to bring this to shader now :))

[leaden solstice]

Sounds fun, good luck! 😄

[wild nebula]

float Pitch(float3 forward)
{
    return degrees(-asin(forward.y));
}

float Yaw(float opposite, float adjacent)
{
    return degrees(atan2(opposite, adjacent));
}

void TrigBillboard_float(float3 VertexPosition, float3 ObjectScale, float3 ObjectPosition, float3 CameraPosition, float3 MinAngle, float3 MaxAngle, out float3 Out)
{
    float3 scaledVertexPosition = VertexPosition * ObjectScale;
    float3 deltaPos = normalize(CameraPosition - ObjectPosition);

    float pitch = Pitch(deltaPos);
    float yaw = Yaw(deltaPos.x, deltaPos.z);

    float3 eulerDirection = float3(pitch, yaw, 0);

    float4x4 constrainedDir = ToMatrix4x4(eulerDirection);

    float4 rotatedVertex = mul(constrainedDir, float4(scaledVertexPosition.x, scaledVertexPosition.y, scaledVertexPosition.z, 0));
    float3 finalPosition = rotatedVertex + ObjectPosition;

    Out = TransformWorldToObject(finalPosition);
}

Worked flawlessly

:))

Now I just have to clamp them, thanks again!

Weeks of headache gone!

[leaden solstice]

That was quick 😄

[rose stag]

Is there a direct way to make and modify an image within code then display it as a texture?

[pine inlet]

hey fellas, how could i rotate a square(blue in picture) in 2d to sort of align itself with a linerenderer(red in the picture) like images 1 and 3? This is what i have so far but the result is similar to image 2

        Vector2 formationNormal = Vector2.Perpendicular(GetFormationMiddlePoint());
        return formationNormal;
    }

    void SetFormationSquare(){
        formationSquare.transform.position = GetFormationMiddlePoint();
        formationSquare.transform.localScale = new Vector2(GetFormationLength(),1);
        float rot_z = Mathf.Atan2(GetFormationNormal().y, GetFormationNormal().x) * Mathf.Rad2Deg;
        formationSquare.rotation = Quaternion.Euler(0f, 0f, rot_z);
        Debug.Log($"Line normal is {GetFormationNormal()}");
    }```

[dusk apex]

Using Vectors, you should be able to move towards the expected Vector instead of managing angles https://docs.unity3d.com/ScriptReference/Vector3.MoveTowards.html

Or do the same with the Euler Angles, quaternion etc.

[prime dune]

hiya chat, i'm wondering if anybody has any advice for the "best" way to go about resetting an enemy after restarting to a checkpoint in my FPS game

[pine inlet]

will attempt, thanks

[prime dune]

right now when enemies die, they get disabled instead of just destroying

i was considering just saving every relevant initial value at Start() but i feel like i might be missing an obvious solution

like perhaps a way to just reset a gameobject to its state at scene start?

although that's probably easier said than done

[rose stag]

One alternate easier solution is to reset the entire scene. Without reseting the scene, your solution sounds good.

[prime dune]

the thing with that is that the entire point of the checkpoint system is to let the player just restart to a certain point in the level

[rose stag]

If you want, you could make the checkpoint ID either a static variable or in a DontDestroyOnLoad game object.

I had a similar problem when I was making a game jam game and I just reset the entire scene with a public static checkpoint ID.

[prime dune]

i've thought about just instantiating all of the enemies when they spawn instead of just setting them to active

but that seems like it could get messy quick

[prime dune]

currently the checkpoints are their own class and i also have a CheckpointHandler class

or i guess script is more apt terming since they're split into their own scripts

[rose stag]

Perhaps the checkpoint handler could be DontDestroyOnLoad. Though I don't know how to check for a scene reload in a DontDestroyOnLoad off the top of my head.

[prime dune]

i think realistically i'm probably just gonna go with the route of saving all relevant properties at scene start and then just setting everything back to that when they respawn

[rose stag]

Depending on the scale of your game and how much actually needs to reload, it may be the best option.

[prime dune]

it just feels messy and unnecessary but that may just be me

i'll see what i can do

[unreal temple]

Destroy all enemies and respawn them

Place spawners in your level instead of enemy prefab instances

Then when they spawn chuck em in a list

When you hit the checkpoint, destroy anything left in the list, and loop through spawners to respawn

Reloading the whole scene is okay too if you can do it seamlessly enough

[rose stag]

If you are curious what I did for my game, here it is. ```cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Checkpoint : MonoBehaviour
{
public static int checkpoint;
[SerializeField] int id;
// Start is called before the first frame update
void Start()
{
if (checkpoint == id)
{
GameObject p = GameObject.Find("Player");
p.transform.position = transform.position;
}
}

// Update is called once per frame
void OnTriggerEnter(Collider col)
{
    if (checkpoint != id && col.name == "Player")
    {
        checkpoint = id;
    }
}

}

I then assigned each checkpoint a unique id in the inspector. This is an old script of mine, I know GameObject.Find("Player") is pretty silly.

[prime dune]

hmmm okay i think i know what i'm gonna try

thanks for the advice folks

[severe coral]

What would be the most efficient way to use a compute shader to edit only a specific region of a texture2d? I don't want to have to send the entire texture through a buffer each time if I only want a fraction of it changed.

Look up a state machine, and if that's not complicated enough for your uses look into a behavior tree

And if I were in your shoes I'd try to make good use of delegates, I don't think they have any terrible performance drawbacks

[swift falcon]

    {
        object playerName;
        if (PhotonNetwork.LocalPlayer.CustomProperties.TryGetValue("playerculture", out playerName))
        {
            player1Culture=Convert.ToString(playerName);
        }
        Debug.Log(player1Culture);
        Photon.Realtime.Player[] otherPlayers = PhotonNetwork.PlayerList.Where(player => player != PhotonNetwork.LocalPlayer).ToArray();

        foreach (Photon.Realtime.Player otherPlayer in otherPlayers)

            }
        }
        Displaytext.text="Player has chosen an object";
    }
}```

Can someone help me with this

The problem is

the Displaytext.text is getting displayed at the start of the game itself

instead of displaying after all the initial code is done

[wild nebula]

What does that Forward() function returns? euler angles/radians?

[leaden solstice]

Forward returns normalized direction vector

[wild nebula]

Oh, so like 0, 0, 1 but * rotation

[leaden solstice]

Yes

[wild nebula]

Ok cool :>

Is it possible to get the Yaw/Pitch angles from direction vector?

Found this

float3 ToEulerXYZ(float3 dir)
{
    float pitch = atan2(-dir.y, sqrt((dir.x * dir.x) + (dir.z * dir.z)));
    float yaw = atan2(dir.x, dir.z);

    return float3(pitch, yaw, 0);
}```

Nvm I don't think its right.

[leaden solstice]

That’s what you’ve been doing tho?

Pitch and Yaw function is for it

[wild nebula]

I figured lookAt camera's object position isn't exactly billboard behavior. They face camera's inverse forward UNITY_MATRIX_I_V.

So I'm trying to convert camera inverse matrix to eulers

Something like this float3 eulerAngles = ToEulerXYZ(Forward(ToQuaternion(UNITY_MATRIX_I_V)))

Then clamp each of their axis.

Actually idk anymore brain is fired atm

void ConstrainedBillboard_float(float3 VertexPosition, float3 ObjectScale, float3 ObjectPosition, float3 CameraPosition, float2 MinAngle, float2 MaxAngle, out float3 Out)
{
    float3 scaledVertexPosition = VertexPosition * ObjectScale;
    //float3 deltaPos = normalize(CameraPosition - ObjectPosition);
    float3 deltaPos = Forward(ToQuaternion(UNITY_MATRIX_I_V));

    float pitch = clamp(Pitch(deltaPos), MinAngle.x, MaxAngle.x);
    float yaw = clamp(Yaw(deltaPos.x, deltaPos.z), MinAngle.y, MaxAngle.y);

[pine inlet]

Alright im back with a different approach that still doesnt work 🤣 , so what i am trying to do is make a square parallel to a line renderer that only has 2 points.
Right now im trying to do this by getting the angle of the line and setting the square rotation to this angle, though it pretty much doesnt work as the rotation is wrong, here's the code i use for setting the rotation:

     Debug.DrawLine(formationLine.GetPosition(0), formationLine.GetPosition(1), Color.red);
     Quaternion angle = Quaternion.FromToRotation(formationLine.GetPosition(0), formationLine.GetPosition(1));
     Debug.Log(angle);
     return angle;
 }
 void SetFormationSquare(){
     formationSquare.transform.position = GetFormationMiddlePoint();
     formationSquare.transform.localScale = new Vector2(GetFormationLength(),1);
     formationSquare.localRotation = GetFormationNormal();
 }```

[mental rover]

it looks like you're rotating by the angle between the two points with this code, instead you need to rotate by the angle between the line and the default angle

[elder totem]

Is anyone here familiar with photon especially with webgl?

[eternal tusk]

is there a way that you can apply a texture onto a gameobject through C#?

[trail torrent]

Can anyone help me? The error for the code is
"IndexOutOfRangeException: Index was outside the bounds of the array."
and the code is

        for (int x = coord.x - VoxelData.ViewDistanceInChunks; x < coord.x + VoxelData.ViewDistanceInChunks; x++) {
            for (int z = coord.z - VoxelData.ViewDistanceInChunks; z < coord.z + VoxelData.ViewDistanceInChunks; z++) {

                if (isChunkInWorld(coord)) {

                    if (chunks[x, z] == null) << error right here
                        CreateNewChunk(x, z);

                }
            
            }
        }

[pine inlet]

Any clue how I would get those?

[frigid anvil]

How is chunks defined?

[trail torrent]

Chunk[,] chunks = new Chunk[VoxelData.WorldSizeInChunks, VoxelData.WorldSizeInChunks];

Chunk is my class, imma send it in pastebin

if you want

[frigid anvil]

Oh, actually I guess I didn't need that. So what happens when coord.x is smaller than VoxelData.ViewDistanceInChunks?

[trail torrent]

imma put the view distance to 3 since world size in chunks is 8

even tho it was 5

[frigid anvil]

The point is that the x is going to start negative, which is out of range for the array.

[trail torrent]

kinda works but if it tries to add something outside the world it does the error

[frigid anvil]

If your world is VoxelData.WorldSizeInChunks, then you want the coordinate reference to be offset from VoxelData.WorldSizeInChunks/2 and cap your view distance using something like Mathf.min(VoxelData.WorldSizeInChunks, coord.x + VoxelData.ViewDistanceInChunks) for instance. It'll need a bit more tweaking to your chunk creation code...

[trail torrent]

ok

alright

thanks for the help!

[frigid anvil]

Sure!

[trail torrent]

the world is just generating chunks but world size in chunks is a int of the for loop in the start so it can generate it

oh i found the error between the line of the error

it checks for coord.x, coord.z but it needs to be new ChunkCoord(x, z)

x, z is the for loop

[mental rover]

diagram to help- Quaternion.FromToAngle(A, B) is going to give you a rotation from A to B, marked by the grey angle, what you want to find is the rotation from X to AB, marked by the red angle

[pine inlet]

alright, thanks!

[trail torrent]

I need help again

[craggy nova]

Can you (or anyone else) elaborate?

to be clear this is the code

{
    Debug.Log(isGrounded + "," + canJump);

    if (context.performed && isGrounded && canJump)
    {
        playerRb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
        isGrounded = false;
        canJump = false;
        StartCoroutine(CheckCanJump());
    }
}```

when I press Space the character jumps. Do I need to use fixed update for this?

I feel like there is no need in this case and none of the tutorials seem to use fixed update for this but I am still not sure

[trail torrent]

Can anyone help me?

[simple egret]

You need to ask an actual question, see #854851968446365696 for instructions on how to ask a question.

[trail torrent]

sorry, i just read it and it said to check in the internet and there was nothing about it, just other errors about it

basically the error is "IndexOutOfRangeException: Index was outside the bounds of the array." on the AddVoxelDataToChunk line

for (int x = 0; x < VoxelData.ChunkWidth; x++){
            for (int y = 0; y < VoxelData.ChunkHeight; y++){
                for (int z = 0; z < VoxelData.ChunkWidth; z++){

                    AddVoxelDataToChunk(new Vector3(x,y,z));

                }
            }
        }

[simple egret]

You need to read further than the first two lines of that channel!

[hollow stone]

There are different ways to do this. You can do things out of callbacks or you can do it by reading values. I would consider cases what happens with the code if there are more fixed frames per update or less, would you have the correct logical outcome in these cases with modifying physics like this?

[trail torrent]

i did

[hollow stone]

Usually says what line of script the error is. So you can start investigating this.

[craggy nova]

I am lost. Aren't there a fixed amount of frames anyways? Or do you mean if there are more fixed update frames than update frames?

[trail torrent]

i did investigate but theres nothing i cant fix ebcause i dont know whats wrong

[craggy nova]

oh, you can alter the fixed update frames with timescale right? you mean that?

[hollow stone]

Afaik the input events are invoked by update frames (aka with your frame rate) if you don't choose otherwise or invoke it yourself, thus there might be more or less frames depending on how fast your application runs. Fixed updated are as named a fixed rate that you set in the project settings, it may run more or less fixed frames dependent on how it matches with your normal frame rate. E.g. if you have 30 fixed frames per second and ~60 frames per second you will roughly get 2 fixed frames per render frame, but it might be 0 or 3 or even more if spikes.

[hollow stone]

Try post more lines of the error then.

[craggy nova]

so in that case the jump can be triggered twice in the same fixed frame instead of once?

[hollow stone]

It could be attempted to be triggered, but you have guards with booleans that would make it not.

[craggy nova]

I do have a cooldown for jump input (.1 seconds) so that shouldn't be a problem

[frigid anvil]

Okay, so this is going to be when you're first creating the data in the chunk, right? So what does AddVoxelDataToChunk look like? Because it sounds like you're doing something in that method that's causing the error. Either that, or you're running old code because you didn't save and restart your game in between.

[trail torrent]

(wrapper managed-to-managed) System.Object.ElementAddr_1(object,int,int,int)
Chunk.CheckVoxel (UnityEngine.Vector3 pos) (at Assets/Scripts/Chunk/Chunk.cs:83)

[craggy nova]

So there are no problems with my code then? Or am I just missing the problem?

[trail torrent]

void AddVoxelDataToChunk(Vector3 pos) {
         for (int p = 0; p < 6; p++){
 
             if (! CheckVoxel(pos + VoxelData.faceChecks[p])) {
                 byte blockID = voxelMap [(int)pos.x,(int)pos.y,(int)pos.z];
                 vertices.Add (pos + VoxelData.voxelVerts[VoxelData.voxelTris[p,0]]);
                 vertices.Add (pos + VoxelData.voxelVerts[VoxelData.voxelTris[p,1]]);
                 vertices.Add (pos + VoxelData.voxelVerts[VoxelData.voxelTris[p,2]]);
                 vertices.Add (pos + VoxelData.voxelVerts[VoxelData.voxelTris[p,3]]);
                 
                 AddTexture(world.blockTypes[blockID].GetTextureID(p));
                 triangles.Add(vertexIndex);
                 triangles.Add(vertexIndex + 1);
                 triangles.Add(vertexIndex+2);
                 triangles.Add(vertexIndex+2);
                 triangles.Add(vertexIndex+1);
                 triangles.Add(vertexIndex+3);
                 vertexIndex += 4;
             }
         }
     }

basically this long code

[hollow stone]

For this case it works. But for some other case it might not, e.g. continuous thrust upwards by input.

[craggy nova]

I see. Thanks

I am actually trying to implement movement right now so I know what you mean

[frigid anvil]

Right, so now you can see from the stack trace that the actual bug is in CheckVoxel at line 83.

[trail torrent]

whats wrong with "return world.blockTypes[voxelMap [x,y,z]].isSolid;"? its ok for me

but says its not working at times

so not ok tbh

[frigid anvil]

Well, the result of voxelMap[x, y, z] could be out of range for world.blockTypes or any of x, y, z could be out of range for their relative dimension in voxelMap. What you want to probably do is log the values, so you can see what thing is out of range when it does fail.

From the stack trace
(wrapper managed-to-managed) System.Object.ElementAddr_1(object,int,int,int)
I'm going to guess that one of x, y, z is out of range for voxelMap for some reason. (Because the method being called is ElementAddr (the address of an element of object indexed by three int values, which is your x, y, z parameters to []). So I'd make sure your x, y, z are within the range expected for your array.

[trail torrent]

imma try to fix it

oh ok im sorry for this because i might realize what was the problem

i had no block types and before i had

oh wait no its still not working

[desert shard]

That's perfectly fine. Why would you need fixed update? It's a single frame event. (Noice the impulse forcemode)

[craggy nova]

I thought so as well but you know how it is, especially when you are tired, you just start doubting yourself

[frigid anvil]

Log your x, y, z. Something's wrong there.

[craggy nova]

Thanks

[trail torrent]

Using Debug.Log on a bool function doesnt work

[frigid anvil]

What? No, on the line before the array reference, log your x, your y and your z values.

[trail torrent]

oh alright

[frigid anvil]

(Probably after line 82 and before 83 of CheckVoxel from what I'm reading...)

[trail torrent]

idk how to do it but im gonna try to fix it

[swift falcon]

question: I have a script that is attached to multiple game objects in my game and I want to disable that script with one click across all the game objects, is there is a way to link them all in an easy way to be able to disable and enable the script on those game object ? btw there is like 100+ game object that contains that one script

also I am trying to disable the script in game mode not in the editor btw lol

so its an event that controls if the script should be active on those 100 game objects or not at a specific time

[frigid anvil]

Do you want to disable as in the GameObject enable type, or make every script instantly know it's not supposed to do something? The latter could be handled with a static variable that is checked by the meaningful methods of the script.

[swift falcon]

what I am trying to do exactly is, I have a "interactive" script that make game objects interactive to the player but when any animtion clip is running I want all game objects to not be interactive anymore until that clip is over

let alone that should happened with every single animation clip that run, so I want an easy way to disable the "interactive" script on everything every time an animtion start

other then hard coding it in every single animtion clip

[frigid anvil]

So...it sounds like you need a central place that the animations are triggered (an AnimationManager essentially) which also knows to tell the script ignore interaction messages and when the animation ends, it tells the script, stop ignoring interaction messages. If the interaction is the 'OnMouseover' kind, then the scripts could just...check a static variable, and return if it's set, so they don't react. I don't like the design, but I also get that it's what you've got, and this approach would work with it...

[swift falcon]

yeah I should try that

ty !

[weak nacelle]

I'd make a disable method on the scripts you want to be disabled and just subscribe the method to a switch method on a static class that can be called from anywhere

[swift falcon]

        }
        await Task.Delay(5000);
        Displaytext.text="Player has chosen an object";
    }
}```

Can someone please help me with this. So basically

I have 2 players in my game

I want the first part of the "TheGame" function to only happen if the player is a masterclient

but the rest should happen for all players

but the display text is not changing for the second player

Is it because the while loop is outside the if condition?

[hollow stone]

I've recently been getting these inspector issues with scripts not loading properly, anyone been noticing something similar? Usually adding a blank line to make the script reload fixes it but not always, but it keeps popping up now and then. Possibly after me splitting the project to a bunch of assemblies.

[thorny rock]

Usually happens when you have uncompilable code and thus Unity is unable to compile all the C# code. It shouldn't just randomly happen without any compiler issues thought.

[hollow stone]

It frequently happens without compiler issues x)

[thorny rock]

Then it's possible you change it from MonoBehaviour to non-MonoBehaviour and thus you cannot attach the script to a GameObject?

[hollow stone]

No this is my Authoring MB acting up. They have been recently moved to assemblies though if that is an issue.

[thorny rock]

Odd 😦

[lethal plank]

guys i have a question

what the speed mean in rigridbody?
m/s or km/h?

[hasty canopy]

Units per second

[thorny rock]

https://docs.unity3d.com/ScriptReference/Rigidbody-velocity.html explains it well I guess. Check the commented code, it's units.

[lethal plank]

units mean it will go like 600 x/y/z per sec?

[hasty canopy]

If speed is set to 600 yeah

[lethal plank]

ohh i got it thanks

[lethal plank]

thank you too

[hollow stone]

Does pressing apply on asmdef do anything special? I'm doing some shenanigans where I'm generating my asmdef by text which might be the cause of it?

[calm delta]

how do i get an array of gameobjects of all the objects in the scene that have a script with a specific interface?

[simple egret]

Use FindObjectsOfType and pass the interface as the type argument

Returns an array

[calm delta]

that doesn't work

i'm looking for an array of GameObject

[simple egret]

Then you need more transformation on the array. Loop over it, and for each item cast it to MonoBehaviour (will fail if the type implementing the interface isn't a MB), and get its gameObject field

Or, a smarter way would be to add a property in the interface like this

GameObject gameObject { get; }

Which allows you to get the GameObject directly without casting

It works because gameObject is already defined, in MonoBehaviour, which satisfies the interface requirements

[calm delta]

i see, yeah

the problem im having now is that it won't allow me to use an interface as the type in FindObjectsOfType

[simple egret]

Ah, so it's not like GetComponent, that doesn't have a type constraint

Oh well, you'll have to search for all MonoBehaviour instances and filter them to the ones that implement your interface

[calm delta]

yeah this is what i did, it should work

[simple egret]

You can do if (monoBehaviour is IHealthControl) to type check directly

[calm delta]

ooh thank you

[simple egret]

Eliminates a mistake that if the MonoBehaviour itself doesn't implement the interface, it will still try to find another MonoBehaviour on the same object that does

[calm delta]

got it, yeah

[sage latch]

You can also do this with linq. To me it looks cleaner but that's just preference

List<GameObject> candidates =
            FindObjectsOfType<MonoBehaviour>()
                .OfType<IHealthControl>()
                .Select(mono => mono.gameObject)
                .ToList();

[calm delta]

oftype always yielded in me getting an empty list for some reason, and the system i have rn works so

thank you though!

[inner escarp]

Hi guys, I have a bit of an issue i can't really tell why its happening but the objects aren't spawning where i need them too:

    void Start()
    {
        //Already have a list of 15 GameObjects, now a list to hold the 15 positions of those objects
        listOfTargetSpawnLocations = new List<Vector3>();
        for (int i = 0; i < listOfTargets.Count; i++)
        {
            GameObject objectToTakePositionFrom = listOfTargets[i];
            Vector3 objectsPosition = objectToTakePositionFrom.transform.position;
            listOfTargetSpawnLocations.Add(objectsPosition);

            //Deactivate once it's position is recorded so its not visible at start.
            objectToTakePositionFrom.SetActive(false);
        }
        Debug.Log(listOfTargetSpawnLocations.Count);
    }

//Throughout update there are several clauses before SpawnAtRandomTarget is called. When it is, the objects spawn nowhere near the position i have them in and seem to spawn on top of each other.

    private void SpawARandomnTarget() {
        GameObject randomObject = listOfTargets[Random.Range(0, listOfTargets.Count)];
        Vector3 randomPosition = listOfTargetSpawnLocations[Random.Range(0, listOfTargetSpawnLocations.Count)];

        //Activate the object and set it in on of 15 random positions
        randomObject.SetActive(true);
        randomObject.transform.position = randomPosition;

        // Find the direction from the object to the player
        Vector3 direction = player.transform.position - randomObject.transform.position;
        Quaternion targetRotation = Quaternion.LookRotation(direction);
        transform.rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, objectRotateTime * Time.deltaTime);
        justSpawned = true;
    }
        private IEnumerator Countdown() {
        for (float t = countDownTimer; t >= 0; t -= Time.deltaTime)
        {
            countDownElapsedTime += Time.deltaTime;
            // Wait until the next frame
            yield return null;
        }
    }

I have a bunch of targets on a wall:

Everything else executes quite well, just when it gets to here.

And i don't understand how the position can move so far, when i'm activating it in its current place, saving its position and then deactivating

And then setting its position again at Spawn method

Eyyy i don't know why but it works now lol

[pallid wasp]

Hey, I´ve been working on a car controller for some time now and no matter which approach I choose for this, the rigidbody always goes crazy as soon as it hits the collider of the floor. Even if I start a new project, that error is still existent. I also already tried the edy´s vehicle physics, but the result is the same

[thorny rock]

Without properly looking at the code, maybe it's the difference between local position and world position?

Is there any explanation why array is almost fully null?

No Error has popped

[hollow stone]

I disabled my assembly def generator and redownloaded the project. This is the stuff I'm getting which doesn't help very much. It's weird that it complains e.g. "'SpaceCraft.Server.RemoveTeamTriggerTag' is missing the class attribute 'ExtensionOfNativeClass'!" when there is a RemoveTeamTriggerTagAuthoring class instead which seems to be the one that is attached to the gameObject?

[unreal temple]

I've seen this extension of native class thing before. I think it's because you have a non-monobehavior class attached to a game object as a component.

Possibly caused by a script change or meta file mixup.

Also hi! 👋

@hollow stone what is an assembly def generator for?

[hollow stone]

I think I figured it out. Either it was that it was marked only for editor or not auto referenced 🙃

[unreal temple]

Ah nice

[hollow stone]

I have a script where I set up a template assembly definition x)

[unreal temple]

Ah I see. Damn you must have a lot of assemblies.

Is this the same space ship game?

[hollow stone]

Yes, just recently got back to it after releasing Lords & Villeins with Michal : )

[unreal temple]

Oh nice. Congrats, planning on checking it out soon. Saw potato mcwhiskey playing it the other day. Amazing.

[late wharf]

is it public static const or public const static?

[late lion]

Neither. const is always static.

[late wharf]

that works

How do I reference a namespace from another assembly? I have code in a package that I want to change, and I have a script in the main assets folder of the project. The script uses a namespace. In the package file, I tried using myNamespace at the top and it says it couldnt be found. Any ideas?

[leaden solstice]

Are you saying you want to reference your main assembly code from your package

[toxic notch]

Yes

[leaden solstice]

Is the package your own or added from package manager?

[toxic notch]

Added

[leaden solstice]

Then it’s readonly. You cannot and should not modify it

[toxic notch]

It's not readonly I have modified it

I bought it from the asset store

Not sure if that differs from like a default unity package

[leaden solstice]

That’s not really UPM package, Unity made it confusing

Anyways you need to look into assembly definition if that is the case

[toxic notch]

OK I'll take a look, thanks

Is there any way to access the origional mesh of a combined mesh?

[spring lava]

I have a problem accesing a datafield
I want to drop items out of my inventory and the amount of items that i am currently holding.
So the itemdropper script works the way that i get the prefab of the item that is currently in the slot of the item that i have pulled outside of the inventory
then i instantiate the prefab and wished position and remove it out of my inventory
all of that works fine
how i get the prefab is by calling the struct ItemSlot that stores the public InventoryItem item
the public InventoryItem item stores all kind of data like rarity and also the prefab. The prefab itself has a Item Pickup Script on it
The Item Pickup Script has a reference to ItemSlot itemSlot and that itemslot has access to the quantity that i want to access, since i want to change the int quantity that exists within all of this, but i want to only change it, whenever i am actively dropping my item out

        TerrainData terrainData = terrain.terrainData;

        int alphaMapWidth = terrainData.alphamapWidth;
        int alphaMapHeight = terrainData.alphamapHeight;

        float[,,] splatmapData = new float[alphaMapWidth, alphaMapHeight, 2];

        for (int y = 0; y < alphaMapHeight; y++)
        {
            for (int x = 0; x < alphaMapWidth; x++)
            {
                float value = Random.Range(0.0f, 1.0f);
                splatmapData[x, y, 0] = value;
            }
        }

        terrainData.SetAlphamaps(0, 0, splatmapData);

        terrain.materialTemplate.SetTexture("_Control", texture);
        terrain.materialTemplate.SetTextureScale("_Control", new Vector2(grassTiling, grassTiling));
    }
}

its placed on terrain, with a texture added to the script

https://hatebin.com/obahcvmcac Any idea how to optimise my rainbow triangle drawing script? I think it's a nice effect but it runs slow at high resolutions. Obviously, I will use MUCH smaller textures than 1024x512, like 64x32, but it would be great to know how to further optimise my script so it doesn't cause lag when I do a bunch of effects like these.

"If you're constantly regenerating a texture at runtime, it may be faster to generate an array of pixel colors and set all of them at once with SetPixels."

If you have a reference to the Mesh assets of the meshes that get combined somewhere else, those should be unmodified.

hmmm ok

Hey guys, I'm trying to get 2D top down multiplayer movement work. But for some reason my character isn't moving at all. Here is the script, but I have a feeling that it isn't the scripts fault, let alone the multiplayer part. Maybe it's something I forgot in inspector?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Mirror;
using UnityEngine.SceneManagement;

public class PlayerMovementController : NetworkBehaviour
{
    public float speed = 5f;
    public GameObject PlayerModel;

    private Vector2 movement;
    public Rigidbody2D rb;
    //private Animator anim;

    void Start()
    {
        PlayerModel.SetActive(false);
        //anim = GetComponent<Animator>();
    }

    void Update()
    {
        if(SceneManager.GetActiveScene().name == "Game")
        {
            if(PlayerModel.activeSelf == false)
            {
                SetPosition();
                PlayerModel.SetActive(true);
            }
            if(isOwned)
            {
            //Runs ProcessInputs after it checked if you have the authority
            ProcessInputs();

                        // Set Animations
            /*anim.SetFloat("Horizontal", x);
            anim.SetFloat("Vertical", y);
            anim.SetFloat("Speed", Mathf.Abs(x) + Mathf.Abs(y));*/
            } 
        }
    }

    public void SetPosition()
    {
        transform.position = new Vector2(Random.Range(-1,1), Random.Range(-1,1));
    }

    void FixedUpdate()
    {
        if(isOwned)
        {
            // Apply Movement
            rb.velocity = new Vector2(movement.x * speed, movement.y * speed);
        }

    }

    void ProcessInputs()
    {
        float moveX = Input.GetAxisRaw("Horizontal");
        float moveY = Input.GetAxisRaw("Vertical");

        movement = new Vector2(moveX, moveY).normalized;
    }
}

Thank you very much! The code now runs super fast! https://hatebin.com/qkvmwwbrdq

Solved it

I'm trying to add camera collision but it doesn't seem to work. My main camera is a child of an empty game object that is used as transform, which is a child of another empty game object, I am thinking that might be the issues. Here is the code.

    private void CollideWithWalls()
    {
        RaycastHit hit;
        float distance = cameraObject.nearClipPlane;

        if (Physics.Raycast(transform.position, cameraPivot.transform.forward, out hit, distance))
        {
            if (hit.collider.gameObject.tag == "Wall")
            {
                float distanceToCollision = Vector3.Distance(transform.position, hit.point);
                transform.position = transform.position + cameraPivot.transform.forward * (distanceToCollision - distance);
            }

            // Debug line to visualize the raycast
            Debug.DrawLine(transform.position, hit.point, Color.red);
        }
        else
        {
            // Debug line to visualize the raycast
            Debug.DrawLine(transform.position, transform.position + cameraPivot.transform.forward * distance, Color.green);
        }

        // Print the values of the raycast variables to the console
        Debug.Log("Raycast hit: " + hit);
        Debug.Log("Raycast distance: " + distance);
    }```

RaycastHit has a distance field btw

[versed rain]

So should that value be altered or?

[quartz folio]

Just noting that there's no reason to calculate it yourself

[versed rain]

Oooh
