Everything is up in the air, if so.

[mint moat]

https://paste.myst.rs/35t3im0c

complete script

Each Rounds is fired after a certain time gap, until all the rounds are fired. Here the timeBetweenRounds is 1 seconds, so each new FireRound Coroutine should start every 1 second. Now lets look inside the FireRound Coroutine. FireRound Coroutine is responsible for firing bullets after a certain timeBetweenBullets time, until all the bullets are fired. Here each bullet is fired after 0.1 second, so each FireRound Coroutine should end after 0.4 seconds as the number of bullets fired per round is set to 4.

[dusk apex]

yield return timeBetweenRoundsWaiter; // cached WaitForSecondsRealtime - Minimum wait time
yield return stillFiringBullets;//Wait till done firing```It's still yielding between rounds. It should not be immediately firing differently than you had so before..

Something else has changed etc

[mint moat]

Round Started : 
------ Bullet Fired -- took 0.1 second
------ Bullet Fired -- took 0.1 second
------ Bullet Fired -- took 0.1 second
------ Bullet Fired -- took 0.1 second
another 0.6 seconds wait
Round Started : 
------ Bullet Fired -- took 0.1 second
------ Bullet Fired -- took 0.1 second
------ Bullet Fired -- took 0.1 second
------ Bullet Fired -- took 0.1 second
another 0.6 seconds wait```

[dusk apex]

Round Started
  Bullet Fired 1
Wait for x seconds
  Bullet Fired 2
  Bullet Fired 3
  Bullet Fired 4

[mint moat]

Thats the issue from the starting, It shouldn't fire next round immediately

[dusk apex]

It shouldn't.

[mint moat]

but here it does

[dusk apex]

yield return timeBetweenRoundsWaiter; would prevent it as you originally had it.,

Check your inspector.

Maybe some values default with the amount of changes you've made.

[mint moat]

Ok so let me record the insepector and share the script used .

[dusk apex]

Reminder that the yielding of time is immediate and not after the other coroutine has finished.

[grave crane]

does onDrawGizmos work in a StateMachineBehaviour?

[dusk apex]

If you're wanting to yield 0.6 seconds after the other has finished, you'd yield the start of the other coroutine.

Or yield wait until the other coroutine has finished before yielding to time.

private IEnumerator FireRounds()
    {
        int roundsFired = 0;
        while (roundsFired < maximumNumberOfRounds)
        {
            Debug.Log("<color=yellow>Round Started</color>");

            yield return StartCoroutine(FireBullets());
            yield return timeBetweenRoundsWaiter; // cached WaitForSecondsRealtime - extra wait time
            roundsFired++;
        }
}
private IEnumerator FireBullets()
{
        int numberOfBulletsFired = 0;
        while (numberOfBulletsFired < numberOfFiresPerRound)
        {
            Debug.Log("Bullet Fired");
            yield return timeBetweenFiresWaiter;
            numberOfBulletsFired++;
        }
}```

The try catch also isnt working

[dusk apex]

It shouldn't be non zero if you've got an index out of range.

[dusk apex]

What's a Structs?

I'm assuming some custom type?

[mint moat]

With your edit : https://paste.myst.rs/u5w6kzrg

[dusk apex]

If it's a List it would be accurate

[static matrix]

Structs is a list

I would like to note that this function is being called in a 2d for loop, and it works the first time but not subsequent times

public class Chunk : MonoBehaviour

    public bool PlayerIn;
    public Generation Parent;
    public LayerMask Player;
    public Coords coords;
    public List<GameObject> Structs;
    public List<float> Rotations;
    public List<GameObject> FreeStandingObjects;//Some Furniture, Entities. (Lock to floor)
    public List<GameObject> WallLockedObjects;//Doors, Paintings, Vents. (Lock to walls)
    // Start is called before the first frame update
    void Start()
    {
        Rotations.Add(0);
        Rotations.Add(90);
        Rotations.Add(-90);
        Rotations.Add(180);
    }
    public void SpawnStuff(GameObject Struct)
    {
        //Place the Layout
        var Layout = Instantiate(Struct, transform.position, Quaternion.identity);
        //Randomize The Layout's Rotation
        Layout.transform.eulerAngles = new Vector3(0, Rotations[Random.Range(0, Rotations.Count)], 0);
    }
    
//Rest of code isnt important

here is Chunk

[leaden ice]

Show the actual full error message

[dusk apex]

None of that matters. The index out of range states that there are no elements but you're still trying to access the first element.

[static matrix]

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

[leaden ice]

Also Instead of try/catch you should just be checking the Count

[static matrix]

I am

[leaden ice]

Doesn't look like it

[static matrix]

ayy Praetor You god resident good for you

[dusk apex]

Start shouldn't be immediate so instantiating the object would have the list at count zero.

Show your logs of it's size being two.

[static matrix]

imma try and stagger it

I cant actually easily bcause it uses a param

me being stupid

Debug.Log(ChunkData.Structs.Count);
From this, called the line before the error line

the one after the error line does not call

Yo wtf

I put it back in a new try-catch and it worked

fully

all the generation

try
        {
            ChunkData.SpawnStuff(ChunkData.Structs[0]);
        }
        catch (System.Exception)
        {

            Debug.Log(ChunkData.Structs.Count);
        }

how odd

well im going to bed

gnight

[mint moat]

I hope you are getting whats teh problem here

[sinful terrace]

does anyone here know how to apply velocity on the local axis

please help

I've been trying to do it for over two months

[mint moat]

You can convert local axis to global using TransformDirection and then apply the velocity normally...

[cunning trout]

hi!
Is there a way to reference a Light2D in a script?

[mint moat]

using UnityEngine.Experimental.Rendering.LWRP available here

[cunning trout]

hmm

[quartz folio]

LWRP hasn't been a thing for years.

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@16.0/api/index.html

Or just get your IDE to tell you

[hexed pecan]

2 months?
rb.velocity = rb.transform.rotation * someLocalVel or rb.AddRelativeForce should work

Or yeah what volkner said

[sinful terrace]

i made some very dumb code before i knew that

that only broke thins more

thanks

[mystic ferry]

so I'm working on a simple pong clone, and I've realized a problem. When the puck hits the top or bottom of one of the paddles when the paddle is moving, the paddle applies a force to the ball (because the paddles are also dynamic and register a collision). The problem is that I need the paddles to be dynamic to not pass through walls, but I don't want this collision force applied to the ball. How can I make that happen?

making the puck kinematic is not ideal

[cosmic rain]

Are you sure you want to use forces in this scenario? Setting velocity's directly might be a better option. And perhaps making the ball kinematic too.🤔

[mystic ferry]

that would work but there's a LOT of physics I'd have to handle doing it that way

[cosmic rain]

Also, you could stop the paddles from passing through the walls manually too.

[mystic ferry]

I'd like to leave as much as possible up to the physics engine if I can

[cosmic rain]

Well, pong isn't the most physically realistic game...🤔

And applying forces to colliding object based on objects velocities is one of the basic functions of the physics engine, so you can't just disable it easily.

[mystic ferry]

I'll take your solution and make the physics by hand, but I am curious as to how Box2D handles collisions

I read some stuff on Box2Ds documentation but I couldn't really find anything about how collisions are handled in terms of forces

outside of an impulse applied to overlapped figures

[cosmic rain]

It's simply applying forces based on the paddle velocity, mass and collision normal I think.

[mystic ferry]

like uh. Probably not asking my question accurately

eh whatever. I'll just read the docs more. I'm sure i'll figure it out

[cosmic rain]

I mean, what exactly are you looking for? The source code?

The logic is pretty much how you'd calculate that force in real life I think.

[mystic ferry]

I guess I just have a lot of questions that seem obnoxiously esoteric. Like the Collision.contacts array is "a list of contact points generated by the physics engine", but what even is a contact point? how many contact points lie on an edge of a box collider? just one? is it for each vertex?

what about how much impulse is applied to two colliding dynamic rigidbodies?

[quartz folio]

https://docs.unity3d.com/ScriptReference/ContactPoint.html that's a contact point

[mystic ferry]

if I want to use Vector2.Reflect, I feel like I need to understand how the contacts array is fulfilled so I can get the normal accurately. Idk

[mystic ferry]

this isn't deep enough, I already know this much

[quartz folio]

Debug the values, visualise them with rays. Then you can see where they are when you get a collision and infer what that means for you

[worldly hull]

i need to use async inside a coroutine , and i found out something like IAsyncEnumerator

but i dont want to return a type

[cosmic rain]

A contact point is generated by the physics when it detect intersection between 2 colliders. You'd usually only have one.tgey would usually be on the edge of a collider. The force applied is probably calculated from the relative velocity, mass, collision normal and some other properties(like bounciness).

[cosmic rain]

For reflect you can just use the normal of the collision.

[worldly hull]

this is from a coroutine, the function awaiting is retrieving a string of jsondata

in this case, is await same as yield return?

[spring basin]

Hello, why can't I load custom filetypes in Addressables? I use Texturepacker for my games UI which gives me a multiple sprite mode Sprite and .tps file to read the slicing data. When I try to add this to addressables, it fails

Any solution?

[cosmic rain]

No. It's not the "same", but it would wait untill the result is ready to be returned. Share your loadAvatar method definition.

[tidal rampart]

What is the use of void?._.

[cosmic rain]

It means that the method doesn't return anything. #💻┃code-beginner question btw.

[tidal rampart]

[inland arrow]

hi, i made a custom attribute but im not sure how to use it

using UnityEditor;using UnityEngine;
public class Vector4Attribute : PropertyAttribute {}
[CustomPropertyDrawer(typeof(Vector4Attribute))]
public class Vector4Drawer : PropertyDrawer {
    public Vector4 value;
    public override float GetPropertyHeight(SerializedProperty property, GUIContent label) {
        return EditorGUI.GetPropertyHeight(property, label, true);    }

    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label) {
        value = EditorGUI.Vector4Field(position, label, value); }
}```

the purpose is to rearrange how vec4 are displayed in the inspector

[shell scarab]

you'd type [Vector4] but since that's already a type, I'd suggest naming it something else like Vector4ArrangerAttribute, so you'd type [Vector4Arranger]

[inland arrow]

Alright, i'll try that.

alright, i've changed the name, but im getting a similar error regardless

[quartz folio]

The Attribute needs to be in the runtime assembly, and the drawer needs to be in the editor assembly

so if you have put both under an Editor folder, you won't be able to access that code

[inland arrow]

oh, so they can't be in the same script file together?

[shell scarab]

they can be

just surround the attribute with that conditional compilation (idk what called)

#if UNITY_EDITOR
// stuff
#endif

works for me

[quartz folio]

if they are, they would have to be in the runtime assembly and you would use preprocessor arguments, #if UNITY_EDITOR to exclude the drawer and editor using

[inland arrow]

perfect, that worked @quartz folio :) thank you
how do i exclude the drawer, would that be #if not?

#else didn't seem to behave as expected

[quartz folio]

you wrap the drawer and using UnityEditor in the #if UNITY_EDITOR block

that way it only compiles if you're in the editor

[inland arrow]

oh, right

i had them backwards, sorry

[amber haven]

I am having the same problem rn, did u find a solution?

jesus the amount of people who have this same issue is insane, its dumb af that unity havent added it as a built in feature

[thin aurora]

https://docs.unity3d.com/ScriptReference/LineRenderer.SetPositions.html ??

[plucky inlet]

#archived-code-advanced for a possible solution. Just know how to calculate the right positions and use the right shader/layering to get the desired outcome

[swift falcon]

that's advanced?

[plucky inlet]

No but the conversation was there

SteelCrow just mentioned another person in here having the same problem but the conversation was in advanced and too long to move it. rather fix it now and end the topic 😄

[thin aurora]

Yeah okay so LineRenderer works

Took me 2 minutes to google, find a thread mentioning it, and looking up the documentation. Just FYI, very often your question can be googled since there were many people before you with the same question.

[subtle raptor]

Hello, I have been making a script to organise units in my RTS game but been having a little trouble telling them to rotate towards certain direction, e.g. here is the triangle script ```cs
var number_of_unit = Units.Length;
var triangle_base_size = Mathf.Round(Mathf.Sqrt(2*number_of_unit));
var unit_pos = mousePos - unitSpacing * new Vector2(0,triangle_base_size/2);
var unit_count_in_line = 0;
var unit_total_in_line = 1;
foreach(Unit x in Units)
{
x.AI.destination = unit_pos;

            unit_pos.x += unitSpacing;
            unit_count_in_line += 1;
            if (unit_count_in_line >= unit_total_in_line)
            {
                unit_count_in_line = 0;
                unit_total_in_line += 1;
                unit_pos.y += unitSpacing;
                unit_pos.x = mousePos.x - unitSpacing * (unit_total_in_line-1)/2;
            }
        }```

they always point downwards if anyone could give me some pointers on how to get them to look towards a different direction thatd be great, thanks

[plucky inlet]

I am not really seeing a rotation going on here, can you explain a bit?

[subtle raptor]

is just calculates the shape for the units to be in for a triangle formation but the triangle it organises these in always points down I was wondering if there is a fairly easy way to apply a direction for it to point to or if ill have to take a different approch

[plucky inlet]

So the units point downwards or the triangle shape is pointing downwards? Either I am just too dumb to understand or its not clear what you actually wanna rotate.

[subtle raptor]

the triangle shape points downwards

[plucky inlet]

Ahhh, so you want to rotate your calculated triangle. Sounds like you need to create a position array/list to be able to iterate through those points and rotate them around the center of the triangle

[subtle raptor]

yes, sorry im a bit clueless about how to do this, would I use something similar to rotate around? and how would I do that with a vector3 rather then transform?

[plucky inlet]

https://docs.unity3d.com/ScriptReference/Vector3.RotateTowards.html probably?

[amber haven]

I have researched this topic for roughly 2 hours. It is not as simple as you think and if you had actually read the messages clearly you would know that. Your attitude is pretty rude and belittling.

[thin aurora]

Read the messages in a whole different channel? Of course I didn't do that 😄

So I assume LineRenderer.SetPositions is not the solution?

(Also, giving tips is not a case of bad attitude)

[amber haven]

They are in this channel, they are what I was replying too.

[amber haven]

Nope its not.

[plucky inlet]

Back to topic, did you see my solution in advanced? @amber haven Why is it not working for you

[subtle raptor]

ill give it a look thanks

[amber haven]

no I didn't see it, ill look over it now. thx for the help btw

[thin aurora]

What is the problem with it?

[amber haven]

Rendering a line on the canvas, since line renderer works with 3d positions its very difficult to convert it to 2d while keeping it infront of the camera.

[plucky inlet]

Again, did you check my solution in advanced, last time I ask 😄 I am doing this exactly in that example...

[amber haven]

Yeah I am now, sorry for the hold up I just had to deal with something irl

ill lyk when i have

[thin aurora]

LineRenderer.SetPositions works for that though, you just have to reference the relative point of the objects from the camera instead.

Twentacle indeed provided a solution for it

Is your PNG having an alpha channel?

[rose silo]

Hey, so uh this is a bit of a weird one but i'm basically trying to start a method from a different script and this error above shows up.

Upon further inspection, it turns out that it errors out in both of my methods for some reason but i have no idea why..

this is the code it was referencing in the console

and this is the methods that are having issues

[languid saddle]

im going to check

i dont think so

it uses a material

[plucky inlet]

no, the image you load with your www request, that is an imagefile. you should check that this image file is actually transparent

and of course, your material needs to be transparent not opaque to actually use the alpha channel of your png

[languid saddle]

yes, the image is transparent

[languid saddle]

im going to see that

im trying with this image https://www.pngmart.com/files/4/Cube-PNG-HD.png

yep, it was the material 😅 , thanks

[wary wagon]

How do you get the width of an image that is inside a canvas ?
Basically i want to make an XP bar like this . However, since the parent in white is set to Anchored, the width is always zero .. so i do not know how to set the width of the purple bar

[plucky inlet]

You could just use the texture mode filled and use the value instead of setting the width of an image

[wary wagon]

what do you mean ?

[plucky inlet]

.fillAmount and

[wary wagon]

I do not have these options

[plucky inlet]

You need to use a sprite

[wary wagon]

Ah !

I need to make a full white sprite t hen 😄

Neat ! thanks you

That simplifies all !

[plucky inlet]

exactly, make one 16x16 white sprite that you can tint to whatever you need everywhere and just slice or fill it 🙂

[ember ore]

How would you code such "lines" pointing towards specific coordinates in 3D space?
Couldnt find any theory behind this, so any help appreciated

[thin aurora]

https://docs.unity3d.com/ScriptReference/LineRenderer.SetPositions.html

If you want them to point to a 3d object from a UI object, then you can use Camera.ScreenToWorldPoint to calculate the 3d point from the camera you invoke the method from, and draw a line from the UI object to the 3d object.

[ember ore]

Alright, thanks a lot ! 🙂
Could we even make them a bit curvy?

[thin aurora]

The method takes multiple points so you could split the lines up and create a curve.

Maybe add an option to specify the curve degree and amount of splits/iterations?

[ember ore]

Alright thanks a lot ! ^^

Hi there, I'm trying to find some resources on how to take data from Google Sheets and load it into a game. I'm currently using a javascript script to export, then manually dropping the .json into the project, then using a C# script to organize the data but I'm wanting to streamline the process so when I add data, I don't have to update each script and manually download the .json. Does anyone know of any resources that could make this a more frictionless experience?

[wary wagon]

Can we make the TextMeshPro adjust its rect size in regards to the text size ( not the other way around ?)

[plucky inlet]

you can use a parent layoutgroup / contentsize fitter to get a correct rect around it

any code in a code channel would be useful 😉

I want to store the data so that the users can't access it directly
Is there anyway to achieve that

[mossy gust]

so im trying to write an array of a class, that will allow me to create specific stuff for a cutscene, but the array isnt showing up

i cant figure it out

[quartz folio]

Add [System.Serializable] above Variables

[mossy gust]

ok thank you

[plush sparrow]

???

[uncut plank]

you can encrypt it but people will sooner or later find a way to modify it

so don't rely on it

[static matrix]

You can also try playerprefs, but that has a lot of issues, especially that it can only save float, int, and string

[plush sparrow]

What should I use to save data locally then?

I was wondering if there was a way to store data in the application memory instead of file memory
Kindly tell me the appropriate method to save data

[static matrix]

well the biggest issue with saving data is you need it to keep after the application closes. Unless you expect your users to never close the game or restart their computer....

[mint moat]

@dusk apex I got it working. It turns out, caching the WaitForSecondsRealtime was the problem. I removed the variables and used new WaitForSecondsRealtime and it works now.

I am pretty sure I have heard before, that we can cache those and its a good thing to do instead of returning a new one everytime.

That depends on the sampling rate, but you can use AudioClip.length to get the seconds and calculate the milliseconds from that

its a rigidbody2d if thats what you mean?

this thing

what are its stats

when you do the wallslide, does the superjump only happen right after, or what if you move around first? does it still happen?

the super jump only happens after tha player was on a wall, slid down and then touched the ground from where the player jumped without moving

wait i try to provide the script but my keyboard is tripping

[static matrix]

ok its probably some weird velocity thing, im not sure

[old laurel]

 private bool IsWalled()
    {
        return Physics2D.OverlapCircle(wallCheck.position, 0.2f, wallLayer);
    }
    private void WallSlide()
    {
        if(IsWalled() && !isTouchingGround)
        {
            isWallSliding = true;
            player.velocity = new Vector2(player.velocity.x, Mathf.Clamp(player.velocity.y, -wallSlidingSpeed, float.MaxValue));
        }
        else
        {
            isWallSliding = false;
        }
    }``    private bool IsWalled()
    {
        return Physics2D.OverlapCircle(wallCheck.position, 0.2f, wallLayer);
    }
    private void WallSlide()
    {
        if(IsWalled() && !isTouchingGround)
        {
            isWallSliding = true;
            player.velocity = new Vector2(player.velocity.x, Mathf.Clamp(player.velocity.y, -wallSlidingSpeed, float.MaxValue));
        }
        else
        {
            isWallSliding = false;
        }
    }

not the cs in the beginning bruh

thats the wallslide

[static matrix]

ok, check if isWallSliding stays true after the player comes off the wall

[old laurel]

like this?

        else if(isTouchingGround)
        {
            isWallSliding = false;
        }

nvm not like this

[static matrix]

no i mean literally check in the inspector, public the variable

[golden dove]

Sigh... Recently, when I start Unity, I get errors that the type or namespace "UI Document" can't be found, even though I've been using it extensively and haven't changed anything to it... Anyone know what might be wrong? Using 2020.3.40f1

[static matrix]

Space in name?

[old laurel]

this was very helpful because now i know that the problem is on my wallJumpCoyotetime thing

[static matrix]

thanks!

[old laurel]

i technichally have a timer for walljumping where it allows the player to jump a bit after being off the wall

[golden dove]

Odd. When I change something in my code, save, go back to Unity, the errors go away. Even though I'm not changing anything to do with UI document.

[signal bane]

I wanted to use graphics.blit to save a material to a texture, is that possible? By that I mean I have a complicated character customization shader where you can input multiple mask textures and set colour tints for individual elements. I want to bake the result of that to a single texture

[viral pilot]

Hey, so I have a shader which does some rendering and what not, but I would like to do something where I save the newly rendered frame somehow and then get the average of all the frames rendered from the beginning. A little like the code in this message. How would I go on about saving the render for a singular frame so I can use it later on?

_MainTex is already a variable in HLSL which gets updated when you render it, but I am not sure how I would save the old frame and use it

float4 frag (v2f i) : SV_Target
{
  float4 oldRender = tex2D(_MainTexOld, i.uv);
  float4 newRender = tex2D(_MainTex, i.uv);

  float weight = 1.0 / (Frame + 1);
  float4 accumulatedAverage = oldRender * (1 - weight) + newRender * weight;

  return accumulatedAverage;
}

[cursive shoal]

Hello, how can I face an object in direction of camera but rotation only on Z axis?
I tried with LookAt() but the result is wrong because modify all rotation my object rotate how I wish.

In first pic it's the desired result, the arrow need to be always in direction of the ground but when I start 2 pic it's what happen.

[polar marten]

what is your goal?

[viral pilot]

To render my original shader, and then feed the texture and the last frames texture to the code I showed, so it can render an average of those 2 frames

[polar marten]

i mean bigger picture

hdrp has a recipe for accumulation, and it is robust because it is used in their TSAA implementation

you can look at it. its source code is open

what is your shader trying to do?

like what is this for?

TSAA?

[polar marten]

Anyway my point is going to be you should probably use shader graph and HDRP

[opal cargo]

Hi guys, anyone knows how a raycast can send me a hit with hit.point being origin of the level while I clearly wasn't there?
Using Physics.CapsuleCastNonAlloc( top, bottom, radius, dir, hitArray, dist, ~LayerMask.GetMask("Player"), QueryTriggerInteraction.Ignore);
Where top/bottom/radius are the top/bottom/radius from my capsule collider, hitarray is an empty RaycastHitarray with 10 slots, dist is 0.01f
Reading the collider it tells me he hit the floor, so that's right too.

[viral pilot]

Yeah you right, I probably should. Thanks 😁

[polar marten]

at least look at the hdrp source for how to do accumulation

the RTHandles class gives you accumulation buffers

this stuff is really hard. you can't just shove rendertextures onto a monobehavior

[opal cargo]

Function looks like

float radius = _playerCapsule.radius;
float height = _playerCapsule.height;

// Get top and bottom points of collider

Vector3 bottom = transform.position;
Vector3 top = transform.position + Vector3.up * _playerCapsule.height;

// Check what objects this collider will hit when cast with this configuration excluding itself
int hitLength = Physics.CapsuleCastNonAlloc( top, bottom, radius, dir, hitArray, dist, ~LayerMask.GetMask("Player"), QueryTriggerInteraction.Ignore);
if(hitLength > 0)
{            
    // Sort array by distance from player, only sort part of array that contains the new hits
    Array.Sort(hitArray,0, hitLength, _RaycastComparer);  
    hit = hitArray[0]; 
    Debug.Log("HitLength: " + hitLength + " Hit object: " + hit.collider.name);
    return true;
}
else
{
    hit = default;
    return false;
}

Getting debug logs with

HitLength: 1 Hit object: Floor
Grounded=True Angle=0 Ground normal=(0.00, 1.00, 0.00) Ground point=(0.00, 0.00, 0.00) Distance=0

While Ground point can't be true.
Most of the time it works fine but sometimes I get the wrong normal/point 😕

Also removed sorting, doesn't change behaviour though

Any ideas? Is there a bug within CapsuleCastNonAlloc?

[polar marten]

it sounds like you're doing something pretty complex

what is your goal?

what is raycast comparer?

[opal cargo]

Using the same function for multiple casting purposes, this is ground check

[opal cargo]

Comparer<RaycastHit> _RaycastComparer = Comparer<RaycastHit>.Create((x,y) => x.distance.CompareTo(y.distance));

To sort the array by distance, so I get the closest hit

[polar marten]

i think that is probably the issue

but i can't tell what this is doing

[opal cargo]

Did it without sorting, same issue so this can't be the problem

[polar marten]

i mean i know what you said you want to do, but ordinarily it's pretty straightforward

it looks like you wrote C code in C#

[opal cargo]

Yeah, coming from C/C++ 😄

[polar marten]

well

there's your problem lol

you're worrying about allocations instead of correctness

for something as straightforward and endlessly tutorialized as a ground check

who knows why it's giving a distance=0. it might not even be this code. if the rest of your project is as obscure as this snippet, you will have a lot of bugs

[opal cargo]

So what I wan't to achieve is casting my player capsule into a direction I want to see if there's a slope or wall ahead or if my player stands on something.
Writing my own kinematic character controller by the way

[polar marten]

i have no insight*

because i have no idea what's going on

if you want to write C++ inside of unity, use DOTS

that is what it's meant for

then you can write 100% of the code, including the physics, and it can be as buggy as you want it to be

i'm exaggerating

but really, id on't think ther'es anything wrong with this code

[opal cargo]

I'm using CapsuleCastNonAlloc because it's way faster than the normal CapsuleCastAll most tutorials use

[polar marten]

it doens't really make sense that it would be "way" faster

unless it just does something different

it might not query the latest state of physics or something

[opal cargo]

Doesn't need to allocate the memory all the time

[polar marten]

listen

i'm only going to say this once

but your computer is allocating and deallocating memory literally a million times a second

so don't even start with that

that won't be the difference

this ground check is never going to show up in your profiler

but if "way faster" in dk999 speak means

100x faster

they're different functions

if the only difference is an allocation, it will not impact the profiler speed 99.9% of the time

[pastel remnant]

where do i go for assistance with coding?

[polar marten]

it will impact A column, but not THE column we are talking about

@opal cargo so they are probably different

i think if you are observing weird behavior, they are probably different

it's also possible it does not wipe the array correctly

try overwriting all the elements of the array with a new struct before you call it?

@opal cargo i would like to emphasize i really see nothing wrong with your code as you've written it

[opal cargo]

Tried overwriting but since CapsuleCastNonAlloc gives me how far it wrote into the array I should not need to

[polar marten]

overwriting didn't fix the bug?

[opal cargo]

No

[polar marten]

okay well

try it with CapsulCast

without nonalloc

[thin aurora]

Depending on your experience, #💻┃code-beginner for beginner questions, this channel for general coding questions, #archived-code-advanced for advanced topics

[polar marten]

and see if you get the bug

[opal cargo]

Good thing I come prepared, same bug with this code

Vector3 center = rot * _playerCapsule.center + pos;
float radius = _playerCapsule.radius;
float height = _playerCapsule.height;

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

// Check what objects this collider will hit when cast with this configuration excluding itself
IEnumerable<RaycastHit> hits = Physics.CapsuleCastAll(
    top, bottom, radius, dir, dist, ~0, QueryTriggerInteraction.Ignore)
    .Where(hit => hit.collider.transform != transform);
bool didHit = hits.Count() > 0;

// Find the closest objects hit
float closestDist = didHit ? Enumerable.Min(hits.Select(hit => hit.distance)) : 0;
IEnumerable<RaycastHit> closestHit = hits.Where(hit => hit.distance == closestDist);

// Get the first hit object out of the things the player collides with
hit = closestHit.FirstOrDefault();

// Return if any objects were hit
return didHit;

[polar marten]

okay well unequivocally there is nothing wrong here

i really don't think your snippet has any insights

i am sorry

[opal cargo]

Should I do this in Fixed Update or Update btw?

[polar marten]

the trickiest part of the physics system is running the code at the right time

[opal cargo]

Maybe that's the problem

Doing groundcheck in FixedUpdate though

[polar marten]

it's complicated, but it won't cause big issues

fixedupdate makes sense to me

as long as the "motor" for your character is run consistently before, or after, your "data gathering" stage, you are fine

if you interleave them, it might cause issues. but it would be odd to create incorrect hits

my suggestion is to filter out hits with invalid positions

if you are seemingly doing everything else correctly

is your character moving around a large concave mesh collider geometry?

[opal cargo]

No, just a flat cube.
My code isn't doing something way more complicated at the moment, just a little movement by grabbing input

void handleMovement(){
    transform.eulerAngles = new Vector3(0,_orientation.eulerAngles.y, 0);

    var viewYaw = Quaternion.Euler(0, _orientation.eulerAngles.y, 0);
    Vector3 rotatedVector = viewYaw * _moveInput;
    Vector3 normalizedInput = rotatedVector.normalized * Mathf.Min(rotatedVector.magnitude, 1.0f);
    
    Vector3 movement = normalizedInput * _currentSpeed * Time.deltaTime;

    if(_doJump)
    {
        _velocity += Mathf.Sqrt(_jumpHeight * -2 * (Physics.gravity.y * _gravityScale));
        _doJump = false;
    }
    Vector3 moveDirection = transform.right * _currentSpeed * _moveInput.normalized.x + transform.up * _velocity + transform.forward * _currentSpeed * _moveInput.normalized.z ;

    transform.Translate(moveDirection * Time.fixedDeltaTime, Space.World);
    
}


void handleGravity(){

    if(_isGrounded && (_velocity < 0) )
    {
        _velocity = 0;
    }

}

void FixedUpdate(){
    checkGrounded(out RaycastHit groundhit);
    handleGravity();
    handleMovement();    
}

Can't find any issue and this seems really basic

Orientation is just a cam-object that gets rotated via mouse, nothing fancy

[polar marten]

yeah there's nothing here really

i'm not sure when the physics body gets updated when a transform is moved

[wide fiber]

 void Moving()
    {
        Vector3 movement = p_input.xAxis * transform.right + p_input.zAxis * transform.forward;
        movement *= speed;
        movement += new Vector3(0, rb.velocity.y, 0);
        rb.velocity = movement;
    }```

hi sorry, im kinda lost. how do i rotate using this similar input? 😦 this is under player new input

[opal cargo]

What really bugs me is, the cast finds the floor as shown by the name of the collider, but the .point is just wrong

Is it maybe a overlap problem with the capsule?

Like contactOffset needs to be set or sth?

[polar marten]

i'm sorry i just am not sure

i have never implemented my own kinematic character controller

if i were doing it today, and i had your background, i would use DOTS

because the physics engine is completely open source there

[opal cargo]

Maybe I consider that If I can't solve this.
But as you can see, nothing fancy there. Found an older Unity Forum entry where they discussed this and said it was an issue and fixed, maybe it's Back again

[languid hound]

If I were to use LateUpdate it would override EVERYTHING in Update right? I've not used it often

Like say I set an agent's destination to somewhere in update

And then set it in LateUpdate

It would go to the destination in LateUpdate right?

Yeah it does

[lucid scarab]

hey so im trying to rotate a player based on the angle of the ground under them in 2D, and right now im using two raycasts at the front and back of the player and then using the crossproduct of the points where the raycasts hit the ground to set the player rotation, but for some reason it isnt working.
`void Update()
{
//basic movement
if(Input.GetAxis("Horizontal") != 0)
{
body.AddForce(transform.right * speed * Input.GetAxis("Horizontal"), ForceMode2D.Force);
}

    //raycasts for angle check
    RaycastHit2D fHit = Physics2D.Raycast(fhitspot.position, -transform.up, groundmask);
    RaycastHit2D bHit = Physics2D.Raycast(bhitspot.position, -transform.up, groundmask);

    //rotates the player if grounded
    if(isgrounded)
    {

        body.transform.rotation = Quaternion.Euler(Vector3.Cross(fHit.point,bHit.point));
    }
}`

im still pretty bad at quaternions so im assuming its something to do with my crossproduct to quarternion thing

[potent sleet]

and what exactly is. "Isn't working"

[lucid scarab]

like

it just doesnt turn

i checked if the raycasts were hitting the ground

and they are

[potent sleet]

checked how?

[lucid scarab]

if(fHit.collider.tag != "ground") {Debug.Log("front didnt hit ground");}

i did that for both

[potent sleet]

I think the crossproduct is wrong

[potent sleet]

you want the angle between the two rays ?

and rottate player to that?

[lucid scarab]

the angle between the points they hit

[north gazelle]

Hi guys. My Monobehaviour wasn't teal/working 'sometimes', but all the other stuff was. I reinstalled unity and visual studio 2019 and now almost nothing is 'functional' can you tell me what extensions I need to install to get the squiggly line parts to work properly?

[potent sleet]

hmmm maybe try

        var forwardPoint = fHit.point;
        var backwardPoint = bHit.point;
        var direction = forwardPoint - backwardPoint;
        var angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
        body.transform.rotation = Quaternion.Euler(0, 0, angle);```

[potent sleet]

what does underline say ?

[lucid scarab]

that worked tysm

[north gazelle]

this is the monobehaviour one

[potent sleet]

weird. do you have any duplicate of this script

[north gazelle]

nope

[potent sleet]

try regenerate project files from Unity preferences settings

[north gazelle]

k 30 sec

[north gazelle]

awesome, everything seems to work after regen, ty

[hoary steeple]

hmmm how do I do this correctly? trying to use generics with get set

    {
        get { return null;  }
        set {}
    }```

this just gives me error CS1002: ; expected

[static matrix]

Big brain

sarcasm

not very big brain

but it works

[late lion]

A property can't be defined with generic type parameters, only types and methods.

[hoary steeple]

I see...

[inner yarrow]

How would I go about trying to make a list of components that I will later use for calling a function on the component. The list should be able to contain any type of function, but I will make sure to only add components that contain the correct function in them.

I tried this, but it didn't work because it says that Component does not contain a definition for 'Fire'.
public List<Component> components = new List<Component>();

components[0].Fire();

[simple egret]

I will make sure to only add components that contain the correct function in them.
Then make a list of your component that has that Fire method instead, so you keep type safety

List<MyComponentWithThatMethod>
If there can be multiple component types with a Fire method, use an interface or a base class instead.

[inner yarrow]

Yeah, there can be multiple components with the Fire method, but I'll do some research into base classes. Thank you.

Hmm, maybe there isn't a way to do this. I've used base classes before, I just didn't realize what they're called before; however, I don't think they'll work for this because I want each component to have a Fire method, but each components' Fire method should do a different thing i.e. turret will shoot 3 low damage fast bullets while cannon shoots 1 slow explosive bullet.

[simple egret]

Abstract class, with an abstract Fire method. Inheriting classes will be forced to override the abstract method

Interfaces do the same thing, except you can implement multiple at once. Choose what suits you best

[inner yarrow]

Oh, thank you!

[frosty creek]

hey I've made a finite state machine which uses classes derived from a base state class in order to handle different elements of my enemy code, i was wondering what the best sort of way to enable/disable some of the states at runtime would be? So basically have the ability to add and remove behavior deepening on the enemy type or creature (give example of base state and the logic in enemy class)

[proven plume]

Do you want to accomplish this with just code or with a WYSIWYG editor (inspector or otherwise)?

[cloud smelt]

Has anyone used the tilemap extras plugin to get the gameobject associated with a tile? Im struggling to figure out how to get a reference to the gameobject that was instantiated on a tile. https://docs.unity3d.com/Packages/com.unity.2d.tilemap.extras@4.0/manual/GridInformation.html

[feral mica]

I am reading a midi file (which contains when each note in a song is played). I Start a coroutine for each note played that waits the seconds (with yield WaitForSeconds) until the note is in the song, which are like at least 1000 notes. Is it possible that that many co routines result in them not being accurate anymore? (they have a bigger and bigger delay for me)

Maybe there is a better way to accurately play the notes from a midi file?

[cobalt flint]

You should avoid coroutines for basically exactly what you're experiencing. They're hard to line up, and even harder to keep track of. It will cause major performance issues especially if you're running multiples at once.

[feral mica]

I thought so, but thanks for confirming

any idea how I should do this?

[cobalt flint]

You can use a timer, tied to Time.DeltaTime, which will be more accurate to the computer itself.

You can bury timers inside of timers, use bools to handle which step its on. Set each timer to subtract and check if Timer <= 0 to run the next step. You're going to have a lot of nested timers and bools but itll bne more accurate.

As an alternative I believe there is a way to see where the audio player is in a given song, and set triggers based on that. I can't confirm that is a thing, as I've never done it, but I know with videos you can check which frame its on and run triggers based on that.

[feral mica]

ty

[static matrix]

me rewriting the same lines of code 5 times in a row hoping it will work this time:

it worked this time

[polar marten]

use an asset store package

this is a complex problem

[feral mica]

Well the funny part is that I just realized the notes were not delayed but too fast even (not sure if this is a coroutine bug or some other code bug)

[cobalt flint]

Run the game with profiler on and you'll see how harmful coroutines are on performance, especially for something that is playing audio. You want to avoid them at all costs.

[feral mica]

And I also found some other sort of solution to solve the problem. Just start the coroutines of notes being played within the next 5 seconds. Then call itself in 5 seconds. Then repeat. Then there will only be 10-20 active coroutines of the notes being played in the next 5 secs

would you say 10-20 is a lot?

[cobalt flint]

More than 1 is a lot.

[feral mica]

😄

rip

[cobalt flint]

That's why I suggest using timers. Performance wise you don't want to sacrifice that much computation for audio.

Using a timer and time.deltatime will always target your computers performance and run smoothly. It's a little more coding but in the end saves you a lot of performance.

[feral mica]

But I'm not playing the audio from the midi file, just showing the notes on screen. I have a different single audio file for the full song

Alright I'll take a look at that now

[cobalt flint]

I think you could look into async, which is like a coroutine but runs simultaneously instead of bogging down the order of execution.

That is a lot more advanced though.

[feral mica]

oh yea thats interesting

[onyx saddle]

im using the mirror multiplayer system and i have it so it generates a code and hosts, but the code becomes the auto generated one, but i can move the code reverts to it's placeholder https://pastebin.com/tv9UV6Fa

[inner yarrow]

Does calling StopCoroutine after using a WaitForSeconds that hasn't finished yet in that coroutine mean that the code after the WaitForSeconds will still happen or not. I'm mainly asking because I have a Coroutine on an object, and when that object gets destroyed, I call StopAllCoroutines on it, but I'm getting an error from inside the Coroutine saying that I'm still trying to access it after it gets destroyed.

[cobalt flint]

Once you destroy an object with a script all the script in that object goes to garbage collection

So you can't call a script once its been destroyed. Destroy will also wait till the end of the frame so you can add code after the Destroy and it will still run, but not after the object itself is gone gone

[vagrant harbor]

Hey guys

How do you prevent animations for resetting after a rapid keypress?

So, for example, you press D and it completes the animation sequence but when I rapidly tap D it resets it to the first frame of that animation

[cold parrot]

you need to block your "play animation" code from running while the animation is still in progress

[random sandal]

can anyone explain what this code means

onFoot.Sprint.performed += ctx => motor.Sprint

More or less asking why you do "+= ctx =>" can anyone explain what it means

[cold parrot]

that is an anonymous function being subscribed to an event

equivalent to ```cs
onFoot.Sprint.performed += Handler;
void Handler(CallbackContext ctx) {
motor.Sprint();
}

[random sandal]

So what exactly is ctx I should ask

[cold parrot]

info about the event being raised from the input action

which action it was, timing, phase, state etc.

[random sandal]

I am kinda new to unity I know basic coding but not how the input system works

[cold parrot]

the input system can be a bit confusing

its basically 4 APIs/styles of doing input mixed into one package

[random sandal]

So what does CallbackContext do

[cold parrot]

provides context information

its an event argument

[shell scarab]

This is helpful too:
https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/events/how-to-subscribe-to-and-unsubscribe-from-events

Thanks you two 🙂

Oh wow there is a server for input system in general..

[noble surge]

Is it natural to not use some physics stuff in a 2d Platform game? For example, creating a gravity system instead of using Rigidbody 2D gravity variables

[cold parrot]

very common

most games don't use/want realistic physics for gameplay

[strong cloud]

Yup. I'm experimenting currently with messing with the physics to make jumping more satisfying, e.g. hang time at the peak of the jump, increased horizontal acceleration at the peak of the jump, cutting a jump short

[noble surge]

Ic, thanks for the answers

Why is the attribute constructor not called?

[AttributeUsage(AttributeTargets.Delegate, AllowMultiple = false, Inherited = false)]
public class GenerateEnum : Attribute
{
    public GenerateEnum(string s)
    {
        Debug.Log(s);
    }
}
``````cs
public class StringSplitter : MonoBehaviour

[late lion]

Attributes are just metadata and cannot do anything by themselves. The constructor is called when the attribute is obtained through Reflection, through the GetCustomAttributes method.

[shell scarab]

ah, thank you.

[unreal zinc]

Hi folks, so I'm new to unity but experienced with coding and C# so idk if i'm in the right channel, anyway I'm trying to understand the Unity project folder structure and where I should be placing my code. I use visual studio and my instinctive way to try and start a Unity project is to put the bulk of my game's code in a regular class library so that I can use it elsewhere, however it seems like Unity wants to be the 'root' of everything and not just a component in a larger project. Specifically the thing I'm trying to figure out is how to reference a .NET class library project (visual studio project) in a Unity project. So far all I've seen is that I need to take the DLL for the library and drop it into a 'plugins' folder, but that creates a need to have like a multi-step process every time I recompile my class library

[cold parrot]

think of a unity project as a .Net solution, you can make projects inside that solution with asmdefs (unity variant of .csproj), to add a .dll, you just need to put it somewhere inside /assets, if you have no asmdefs, all code will be compiled into a default project

[unreal zinc]

alright so that's kind of what I'm afraid of, that Unity and Visual Studio are constantly 'fighting' over who gets to be the 'solution'

[cold parrot]

VS and Unity should not be fighting

when configured correctly

[unreal zinc]

i don't mean literally but i mean like, conceptually

like having two friends who both think they should decide what the group is having for dinner

[cold parrot]

no

they do not do that when configured correctly

the unity VS plugin takes care of that

it generates all the required files to make VS believe everything is copacetic

if you edit the project files in VS, they get corrected immediately

[unreal zinc]

yea, i'm using that plugin. I don't want to take up all your time - can you recommend a guide for setting up a proper folder structure and organization system in this type of case?

[cold parrot]

there isn't really a canonical way, but what works well for many people is making "module folders" along the lines of a traditional .net project Core/Shared/ModuleA/ModuleB/etc.

inside those its convenient to follow the recommeded unity package structure, i.e. 3 basic folders: Runtime/Editor/Assets

Runtime is for runtime only scripts, editor for stuff that depends on UnityEditor namespace and assets for anything serialized/art/models etc.

you'd keep any assets or plugins that do NOT have asmdefs in a folder named "Plugins" which causes them to becompiled to a separate DLL so they don't get recompiled every time you change some code in your app specific protion of the project

typically some assets also rely on specific folder structure, so you'd have to keep those at the root level

[unreal zinc]

hm okay. tbh this seems like a mess but i guess most game engines are

[cold parrot]

its also a common practice to keep vendor assets (art mostly) in a separate root level folder

[cold parrot]

there is no way to avoid a mess in a project that does anything meaningful

best you can do is manage it

you could read the unreal engine best practice/styleguide on how to name and structure things, thats not entirely necessary in unity since you can easily search for types of files but its a great reference point do see how complicated this stuff can get

overall i'd say you can keep up the "put stuff into a library" workflow for the most part, its just way more involved because unity stuff involves so many different data/file types beyond just code and some xml/json and everything is making way more assumptions about what the purpose of the project is

[unreal zinc]

this type of chaos seems akin to what modern ASP.NET MVC apps are like, especially when you start adding additional frameworks, there's just so much 'stuff' that it gets hard to manage even if it's organized well

[cold parrot]

yes exactly, its mostly this, different styles of doing things

there are so many ideas how to approach stuff in unity from really invasive, opinionated patterns like MVC in .NET to just some random person with zero architecture skills making a super useful library in their own style

[unreal zinc]

mmmm describing MVC as 'really invasive, opinionated' is highly accurate lol

[cold parrot]

some really embrace "the unity way", some treat it like the worst idea ever

some like scriptable objects, some hate them

some like events, some don't. and most assets don't use other assets because of licensing restrictions, so everyone always reinvents the wheel

[true palm]

Hey I dont know if this question falls into this catigory but I have a helmet on my player(it is just a capsule) and the camera renders the helmet when you are in the game, I dont want this cause it obstructs most of the screen is there a way to fix this?

[cold parrot]

maybe show a picture of what you mean, typically: disable the renderer or change the model to render in the way you want

[true palm]

The sprite versus the first person view

[unreal zinc]

i see why you want to change it but it kinda looks cool tbh

[true palm]

it does but it just totaly obscures the crosshair so when you ads you cant even see the iron sights

[warm wren]

Just disable the mask when in first person mode?

[true palm]

how do I do that?

[warm wren]

maskGameObject.SetActive(false) get a reference to your mask game object and call this when you are in first person mode

[true palm]

ok

[warm wren]

You could also just disable the mesh renderer instead of the whole game object

[true palm]

ok

[vale wren]

steamworks.net or facepunch?

heard the latter had some security stuff, not sure what it is, but also not sure if it's been fixed

[plucky karma]

Wait, facepunch offers network solution? I thought they have been using steamworks.net all this time? (I'm thinking of gmod?)

[potent sleet]

I think facepunch made the steamworks plugin for c#/unity

bu yeah same facepunch from gmod lol

[void basalt]

They made one of the hundred wrappers that exist for steamworks

unlikely you're going to be making a multiplayer game with just that

[potent sleet]

ya wrapper there ya go

[void basalt]

        for (int i = 0; i < countLoaded; i++)
        {
            UnityEngine.Debug.Log(SceneUtility.GetScenePathByBuildIndex(i));
        }```

Not sure why this is returning an invalid string

I have two scenes in the build settings, yet it's still returning blank.

[potent sleet]

shouldn't that be i instead of countLoaded

[void basalt]

yeah

changed that already

oh wait

no I didnt

[potent sleet]

lol

[daring dust]

it says "myRigidbody of birbscript is not assigned." Hlep me.

[somber nacelle]

have you dragged a reference to the Rigidbody2D in the inspector?

[daring dust]

oh, somehow i missed that part in the tutorial, ty

[wary shadow]

Why does this happen? Its all 0 when it's in vector form but not 0 when taken out individually..

[quartz folio]

Because Vector3's ToString only uses 2 points of precision

https://docs.unity3d.com/ScriptReference/Vector3.ToString.html

[wary shadow]

That is not the question. My problem is whit the values being zero when in vector form and not zero when taken out individually.

[quartz folio]

I literally told you why

The values are the same in both, they're just printed to two points of precision when you use Vector3

[mellow sigil]

Those are very small values close to zero so they get rounded when printing the vector

[wary shadow]

Oh.. now i understand.

[unreal zinc]

1.22E-12 is 0.00000000000012 i think

[wary shadow]

But the values are zero in the inspector.

[unreal zinc]

right, because it's showing you a rounded off number I think

[wary shadow]

So if we set the rotation of a game object zero. Its not actually zero? That doesn't make any sense.

[unreal zinc]

It depends on where your 'zero' is coming from. "float rotation = 0.0f;" should be zero but if you're assigning the result of some computation and thinking it's zero, it may not be due to quirks with how computers handle floating point numbers

[fervent furnace]

1.22E-12 i think this only exists in double….

Is floating has such precision?

[mellow sigil]

Smallest float is somewhere around 1E-38

[unreal zinc]

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

[wary shadow]

These are the values in the inspector.

[mellow sigil]

no wait, that's the smallest negative value

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

[unreal zinc]

honestly @wary shadow you might want to read the MSDN article pages about the System.Single (aka 'float') type, there's a lot of information in there about how those types function

floats don't always roundtrip either. so like, float a = 1.0f; float b = a / 3.0f; float c = b * 3.0f; a == c // false, probably

(fixed, lol, it's late)

[plush sparrow]

Where should I store then?

[fervent furnace]

Oh my fault, single can represent 12e-12 by just setting the mantissa and exponent

[wary shadow]

This some Heisenberg shi*.😵‍💫
So how do i consistently get the exact values in such cases?

[fervent furnace]

Impossible ,compare two floating or double usually |a-b|<threshold

[somber nacelle]

unity conveniently has Mathf.Approximately to compare floats

[fervent furnace]

Or you just you two integers to represent a rational fraction….

But you should compute the simplified fraction each time

[wary shadow]

So in this case, how do i get value of x as zero ?

[somber nacelle]

it basically is 0. as has already been pointed out, that number is incredibly small, it's just been displayed with only 2 decimal places

[unreal zinc]

What's the actual problem though? Are you getting visual artifacts? Z-fighting?

[drifting fog]

Is there a way to combine meshes using AcquireReadOnlyMeshData and jobs?

[wary shadow]

Ok. Fortunately it only gives these wierd values when the rotation is zero. So i might be able to work around it.

[somber nacelle]

what is the issue anyway?

[wary shadow]

I wanted to divide the value of x with another float. So theat was giving me wierd answers.

[somber nacelle]

if you were dividing that number by another float it would still be so incredibly close to 0 that the difference would literally make no discernible difference because the number is already so incredibly close to 0 that it makes no practical difference

[plush sparrow]

How should I store data in Android application to maintain privacy and prevent the user from altering the data?

[somber nacelle]

there are very few sure-fire ways to completely prevent users from altering data stored on their devices. an easy way that would prevent someone casually attempting would be to just serialize to binary and save it as a file in Application.persistentDataPath

if you have data that 100% cannot be modified by users then it should be stored on a server that the game contacts to get and verify data. of course this would mean that the game has to have an internet connection to function

[potent sleet]

SQLCipher is probably an option too if you want offline db storage

https://github.com/sqlcipher/sqlcipher#encrypting-a-database
https://learn.microsoft.com/en-us/dotnet/standard/data/sqlite/encryption?tabs=netcore-cli#installation

[plush sparrow]

So like in only offline games
There's no better options than hashing or encrypting the data?

[potent sleet]

the best imo is always a server

[plush sparrow]

That makes sense

I will look into sqlcipher

Thanks

[ocean river]

can i get support for unity for 3ds here?

i mean the nintendo 3ds
thats a thing

[somber nacelle]

pretty sure there are dedicated forums for that since nintendo is pretty strict about its NDAs

[ocean river]

and where are these forums

all i get is 3ds max and 3d

[potent sleet]

goodluck getting the nintendo unity version

[ocean river]

got it already

i mean, i would be asking

i just cant get the font to work on 3ds

[somber nacelle]

probably the nintendo developer portal which you are surely already signed up on. of course i wouldn't actually know where since i'm not a nintendo dev 🤷‍♂️

[ocean river]

thanks for the help tho

[plush sparrow]

Does unity playerprefs and Android sharedpreferences do the same thing?

[plucky inlet]

Is there any codesnippet to avoid the recttransform values to be stored as an override of prefabs? I have a dynamic content size fitter and it lerps the values, but using this in any kind of prefab just keeps adding the value as an override (makes sense, but we all know what fun it is to have prefabs in UI). So any suggestion is welcome here! 🙂

[vale spade]

Hey Guys, pretty new to unity, starting my first software project (im a Embedded software developer for my normal job). Im currently working on a game, where i have a spawner that spawns objects at a specific frequency. I want those spawned objects to ignore each other in terms of collision but the following doesnt seem to work. Can anyone guide me in a different direction ?

    void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.name == gameObject.name)
        {
            Collider own_collider = gameObject.GetComponent<Collider>();
            Collider other_collider = collision.gameObject.GetComponent<Collider>();
            Physics.IgnoreCollision(own_collider, other_collider);
        }
    }

[thin aurora]

What ends up not working?

Like, what does the code do right now that is wrong?

[vale spade]

the balls still collide

they dont pass trough each other

(sprite is a bit smaller than the collision box

[thin aurora]

Let's debug the code process first.

1. Is OnCollisionEnter executed at all? You can place a Debug.Log down at the start of the method to verify.
2. Is if (collision.gameObject.name == gameObject.name) passed? You can place a Debug.Log($"{collision.gameObject.name}, {gameObject.name}"); down before the if-statement to verify the names of the gameobject and check if they are equal.

[vale spade]

is the $"" similar to f"" in python ?

[thin aurora]

I think so

[vale spade]

cool, i love that feature

Ah ur right the collision isnt triggered

[thin aurora]

I notice the game is in 2d?

[vale spade]

yes it is

[thin aurora]

You need this method, instead of what you have currently: https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html

[vale spade]

doest the collision btw work if i dont have 'is trigger' enableD ?

[thin aurora]

I think so

Try it and see ™

[vale spade]

the debug works now

I'd assume i also need Physics2D instead :d

[thin aurora]

Collision2D yes

[vale spade]

hhmmm

Issue now is, it still collides the on the first frame

and then adds ignore collision and ignores its henceforth

[thin aurora]

I'm guessing Unity adds the exception on the next frame

[vale spade]

yeah can imagine, better sollution would be to find all other balls in start and adds the ignore collision

[hollow kernel]

Hello my physics2d.overlap circle is causing a distortion of 0.651848 x from the nearest wall ( i am trying to make a wall slide mechanic )
When i slide on the wall there is a 0.651848 x difference from the wall but when i remove that code it properly sticks to the wall

-2.02688 ( x value with wall slide on )

-1.375032 ( x value when wall sliding is done and when it sticks to the wall )

what am i doing wrong here

the overlap circle is supposed to be this much but it is more than that for some reason

[hollow kernel]

also this value just changed so will the difference i assume

[vale spade]

bit offtopic, but cool wizard!

[hollow kernel]

thanks

[vale spade]

I fixed it by keeping a list in my ballspawner and adding ignorecollision in the spawner

[thin aurora]

If you have a list, can't you just ignore the collisions as soon as the game starts?

I don't think they need to exist in the scene?

[vale spade]

Im spawning an unspecified number of balls in

and they have a limited lifetime

[thin aurora]

I see

[vale spade]

so the list is gonna limited to 100ish balls

[soft shard]

You could try visualizing your cast with the Gizmos class and OnDrawGizmos/OnDrawGizmosSelected function, or use a premade debugger, Ive found Vertx's very helpful: https://github.com/vertxxyz/Vertx.Debugging - depending how your handling your cast, maybe your players collider may be affecting the cast

[hollow kernel]

okay thank you
also i am using a polygon collider should that make a difference ?

every place i checked they are using a box or a circle so i am just confirming

ok i can now confirm it is the overlapcircle

[hollow kernel]

ok i have figured out my issue thank you so much

the gizmos helped!

[steady valve]

i've encountered a weired question, when i use debug.log to output websocket message, it only print logs when i click on console message. How can I make it flush to console immediately.

[thin aurora]

Not sure what you mean with it only print logs when i click on console message.. What exactly are you clicking if it does not exist?

[steady valve]

message like this

this is the log message when i change id code

and after this there should be chat info coming from websocket

however, those messages only print out when i click on these log blocks

[worldly zealot]

i have a multiplayer game and everything is supposed to start in the menu scene
can i somehow make it so by pressing the play button the scene automatically gets changed to menu scene before the game even starts?

[uncut plank]

set the menu as the main scene

[worldly zealot]

in the editor

[uncut plank]

in the editor iirc it starts with whatever scene you have open

https://answers.unity.com/questions/441246/editor-script-to-make-play-always-jump-to-a-start.html

[red scarab]

What I've done in the past, I always include on each scene a prefab (i call it "SceneManager"), and inside the prefab's script it checks if currentScene == startingScene and if not, loads the starting scene. I think I also called it in OnValidate() so it would always execute before anything else, preventing a false start on any other objects' Awake() methods

[red scarab]

nvm, i didn't do it OnValidate() ...

using UnityEngine;

public class Scenemanage : MonoBehaviour
{
    void Awake()
    {
        GameObject check = //do the check
        if (check == null)
        {
            Debug.LogWarning("No _app detected. Reverting to preload scene.");
            UnityEngine.SceneManagement.SceneManager.LoadScene("preload");
        }
    }
}

[wheat cargo]

Idk but at an official Unity talk at GDC, they literally recommended to avoid PlayerPrefs and just roll your own

[upper hinge]

playerprefs are editable through regedit

making it unsafe

for android games, playerprefs are fine since few people will actually root their phones to have access to the files where the data is stored

[hot torrent]

How do i check if an object in an array has been deleted or is "Missing"?
Do i just do if(GO == null)?

Perhaps this?

[potent sleet]

check the index of the array

[hot torrent]

?

[simple egret]

Yep a simple null check will do. Unity has overriden the == operator to also check for the destroyed state of the objects.

[hot torrent]

mhm, alright, let my try!

[hot torrent]

what about != so i can immediately negate it?

[simple egret]

Same thing, when you override ==, compiler enforces that != is also overriden

[plush sparrow]

Can json work with Android shared preferences?

[upper hinge]

idk, I was just adding a bit of my knowledge about playerprefs in the conversation lol

[hot torrent]

[simple egret]

As long as that thing can take a string to store it somehow, then yeah JSON is supported

[hot torrent]

so this'll work?

[potent sleet]

Contains

[hot torrent]

?

[simple egret]

Yes, for the null check. But no, since you're modifying the list you're iterating on with foreach

[potent sleet]

^

[simple egret]

You should use a reverse for loop to pop elements from the end

[potent sleet]

use a for loop to modify list

[hot torrent]

whut? ._."

[simple egret]

If you run this code you'll get an exception

Collection was modified, enumeration cannot continue
Or something

[potent sleet]

whut and question marks are kinda bad responses.. You should ask what exactly you're confused on..

[plush sparrow]

What's the appropriate method to store data in offline games in Android then?

[potent sleet]

Binary

[simple egret]

Files, dedicated app storage

[plush sparrow]

I am being told that's not secure

[potent sleet]

Binary files aren't easy to read for regular joes

[plush sparrow]

And it's slow to save in external memory

[potent sleet]

if the game is offline why do you care if it's modified

[hot torrent]

oh, my bad! I am confused what you mean by reverse loop,,,

[potent sleet]

like for (int i = list.Count - 1; i >= 0; i--)

[simple egret]

I didn't say the shared preferences were excluded though. You can still use them whatever they are, as long as there's a way to interact with it that can take in strings (your JSON) and give them back.

If you need security, then encrypt the file. A determined user can still decompile your app to retrieve the encryption key, though. The most secure way to store data is to do so, on a server

[hot torrent]

ur right ._.

so then how would i do it?... without referencing it...? or what is going wrong?

[simple egret]

You do it with the reverse for loop

[potent sleet]

you need a for loop whenever you want to modify a list while iterating

[hot torrent]

mhm, and what should that loop do?

wait, lemme think!

[simple egret]

It throws the exception to avoid getting lost and giving random elements (or worse). It checks the "version" of the list each time it goes to the next element, and if it's different from the last "version", then the collection changed, throw!

[potent sleet]

By iterating over the list in reverse order, can remove elements from the list without affecting the index of the remaining elements

[hot torrent]

so this goes over the list in reverse?...

[potent sleet]

pretty much

[hot torrent]

but why go over it in reverse?

and not,,, forward?

[potent sleet]

iterate over the list in forward order, removing elements iirc cause the indices of the remaining elements to shift, which could cause errors or unexpected behavior

[simple egret]

When you Remove an element, all the following elements shift right so they take the empty space

[hot torrent]

isn`t that good?

[simple egret]

If you iterated forwards, then you would start skipping elements as the loop doesn't account for the shiftings

[hot torrent]

so this is how i should do it?

[hot torrent]

ooooh!... okay got it!

so it would always skip the 3rd entry, if 2 was null?

because 3 moves into 2's slot!

aaaah!

damn!

i didn`t think of it like that!

Thanks alot!

[simple egret]

You'll notice now that your scoreboard text is backwards, probably, as the thing is now fully reversed

[hot torrent]

oh

[simple egret]

Adding from the start of the text, instead of the end will fix it. And also you can use PlayerList.RemoveAt(i) since you now know what place to remove, instead of what object

[hot torrent]

what will it remove then?...

oh right...

nevermind

[spiral geyser]

https://hastebin.com/share/mapicizoje.csharp
Essentially what is going on is that I am moving the gameObject that the script is attached to back and forth between a undefined set loop of transforms using a horizontal input,
when going forward through the transforms, it will select the next one in line as the one to go to, however when going backwards for some reason, it doesn't select the one before it as the one it should be heading towards? (when it should)
any ideas of why this is happening? (Unity 2D URP)

[tall kettle]

how would i go about having parts getting glued together when someone in vr presses a button while holding it to another part and then when they press another it gets unglued?

[leaden ice]

parent them?

[tall kettle]

oh this sounds way easier than i thought

[spiral geyser]

An easy way to have the gameObject's follow one another is to parent them, and if you were to move one gameObject next to the other gameObject before parenting them, it would give the impression they were glued together

[potent sleet]

if you're using rigidbodies you def need joints 🙂

[tall kettle]

im gonna try putting one interactable in the other and see if i can still grab it how i want it to work

[polar marten]

i think you should use an asset store asset to do this

there are really good ones

like VR Interaction Toolkit

[tall kettle]

i already am using that

[tall kettle]

this did not turn out well

[polar marten]

maybe carefully read the docs

[polar marten]

do you know how to program

[tall kettle]

no

well not in C#

[potent sleet]

start from the basics

[elder hollow]

    public void Jump()
    {
        if (numberOfJumps < maxNumberOfJumps)
        {
            numberOfJumps++;
            rb2D.velocity = new Vector2(rb2D.velocity.x, jumpForce);
        }
    }

    private void FixedUpdate()
    {
        direction = playerInput.direction;
        Vector2 move = new Vector2(direction * moveSpeed, 0f);
        rb2D.AddForce(Vector2.ClampMagnitude(move, 16), ForceMode2D.Impulse);
    }

i have this jump and move script but while im in the air my character moves way faster and clamping it doesnt stop that

[oblique spoke]

You are clamping the amount of force you are adding, not the total force. It's most likely moving faster in air due to lack of friction.

[rigid island]

Hello.
I'm trying to do this but with code

here is what I'm trying :
https://www.redblobgames.com/grids/hexagons/implementation.html#shape-triangle

I can't get this to work in C# though with tilemap.
Anyone know how I can get this working?

unordered_set<Hex> map;
for (int q = 0; q <= map_size; q++) {
    for (int r = 0; r <= map_size - q; r++) {
        map.insert(Hex(q, r, -q-r));
    }
}```

[leaden ice]

wouldn't this be the exact same algorithm I helped you with before?
The only difference is you replace the neighbors() function with one that only returns the northest/northwest neighbors

[rigid island]

Yes You did help me last time ty, but I have no clue how to modify this to do that 😅

this is the one from last time
https://hatebin.com/nzakuqzjdu

[leaden ice]

Pretty sure I just explained it 😉

The only difference is you replace the neighbors() function with one that only returns the northest/northwest neighbors

[rigid island]

AH Ok I will try that

[rigid island]

does the foreach need to change because I can't iterate through only 1/2 directions

Ok I think I got it ```cs
List<Vector3Int> Triangle(Vector3Int start, int maxDepth)
{
Dictionary<Vector3Int, int> depths = new();
Queue<Vector3Int> fringe = new();

    depths[start] = 0;
    fringe.Enqueue(start);
    while (fringe.Count > 0)
    {
        Vector3Int current = fringe.Dequeue();
        int currentDepth = depths[current];
        if (currentDepth >= maxDepth) continue;

        var neighborDepth = 0;

        foreach (var neighbor in current.neighborsUp())
        {
            if (!depths.TryGetValue(neighbor, out neighborDepth))
            {
                depths[neighbor] = currentDepth + 1;
                fringe.Enqueue(neighbor);
            }
        }
        Debug.Log(neighborDepth);

    }

    return depths.Keys.ToList();
}```

@leaden ice is there a more modular way to this for the directions though, seems inefficient ?

  public static Vector3Int[] neighborsUp(this Vector3Int vector)
    {
        return new Vector3Int[2]
        {
            vector.northeast(),
            vector.northwest(),
        };
    }```

[fervent topaz]

[leaden ice]

you could have the search method take a delegate in for the neighbors function

so you can the search method

[rigid island]

do you know what that would look like ? I'm a little confused on this part

I tried gpt it's saying I could pass the direction as parameter and then do this
Vector3Int[] directions = new Vector3Int[1] { Vector3IntExtensions.east(Vector3Int.zero) };

List<Vector3Int> Triangle(Vector3Int start, int maxDepth, Vector3Int[] directions)
{ etc.

foreach (var direction in directions)
        {
            Vector3Int neighbor = current + direction;
            if (!depths.ContainsKey(neighbor))
            {
                depths[neighbor] = currentDepth + 1;
                fringe.Enqueue(neighbor);
            }
        }```

doesn't work though 🪦

Hello there!
I need help with a method

In the game there are row gameObjects which have tiles as children and I wrote a method to get the tiles of multiple rows at once which is called GetTilesOfRows() . Therefore I looped the GetTileOfRow() method. The problem with this was, that I wanted all the tiles that I got of every row to be returned in one array, the finalArray. Somehow a IndexOutOfRangeException occurs in the line allTiles[j] = tempAllTiles[j];.

    {
        GameObject[] allTiles = new GameObject[0];
        GameObject[] tempAllTiles;
        int allTilesAmount = 0;

        for (int i = 0; i < rowNumbers.Length; i++)
        {
            int currentRowNumber = rowNumbers[i];
            GameObject[] currentTiles = GetTilesOfRow(currentRowNumber);
            int currentTilesAmount = currentTiles.Length;

            // tempAllTiles has empty values until the currentTiles begin
            allTilesAmount += currentTilesAmount;
            tempAllTiles = new GameObject[allTilesAmount];
            for (int j = 0; j < currentTilesAmount; j++)
            {
                // newTileIndex is the index of the allTilesArray until where the new tile will be
                int newTileIndex = allTilesAmount - currentTilesAmount + j;
                tempAllTiles[newTileIndex] = currentTiles[j];
            }

            // put the old tiles from previous rows from allTiles and the new ones from tempAllTiles together
            int indexWhereCurrentTilesBegin = allTilesAmount - currentTilesAmount - 1;
            for (int j = indexWhereCurrentTilesBegin; j < allTilesAmount; j++)
            {
                allTiles[j] = tempAllTiles[j];
            }
        }

        return allTiles;
    }```

[leaden ice]

GameObject[] allTiles = new GameObject[0];

your array explicitly has size 0

so obviously trying to put an object anywhere in this array will result in index out of range

You will need to either:

• initialize your array to the correct size (you need to be able to calculate what the final size of the array will be)
• use a List instead, which you can use Add on and it will automatically grow as required.

[fair sierra]

Okay, thank you very much! I think I will go by the list because in my opinion the code is to circuitously anyway

[winged mortar]

Does every row have the same amount of children?

@fair sierra

[fair sierra]

yes

[winged mortar]

Then you could, if you wanted to, really simplify your code want some help?

[fair sierra]

im not shure if later on the amount of children per row could vary

but still thank you

[winged mortar]

Got it, you can probably do this in a single line of code though =p

Look into IEnumerable.Select() and IEnumerable.SelectMany()

[fair sierra]

i´ll definitely do that, thanks

[broken trail]

is there a way to do the following?

string method = "feedburger";
method();

private void feedburger()
{
return;
}

basically call my function using a string variable

just looked it up after figuring out how to word it. Is it Invoke?
update: I think it is

[sterile tendon]

I have a master clock that tells me how many beats have elapsed, and I'm trying to add in the ability to drag in new audio clips so they start playing at the correct time. Here's my code for getting the correct beat time:

            int playTime = (int)(main.beatsElapsed * 60f * audio.clip.frequency / baseTempo);

for some reason, this makes it play at the wrong time. Is there some sort of math error I'm making?

the base tempo is the bpm of the audio clip I'm putting in

oh my god it's because the beats elapsed started at 1 not 0

[fast wraith]

So I followed the Quickstart for configuring Visual Studio 2022. I'm using Unity 2021.3.22f.1. I installed the Unity dev workload, configured the editor to use VS2022, but intellicode still isn't working. I've tried restarting the hub and VS and Unity but nothing seems to work. Also, VS2022 doesn't show up in the Unity Hub Installs/Modules. Any other tips? Reboot my machine? Sacrifice a lesser goat?

[polar marten]

yes, but if you are doing this, you are doing something wrong

[polar marten]

it doesn't work that way

it will still be slightly off

[sterile tendon]

yeah I realized afterwards

[polar marten]

you should use an asset for sequencing audio or research it more

[sterile tendon]

yeah I found a tutorial for it I'm using now

[strong cloud]

There's a specific package you gotta install with the vs code thing. It's like "desktop build tools" or something

[sterile tendon]

what assets would you recommend?

[polar marten]

not sure, i haven't used them so i can't give a real rec

you can also try the unity timeline which specially treats audio sequencing

you can use playablegraphs too

[upbeat carbon]

how do you move entities now that TransformAspect is gone? I'm just starting to learn aboutt entities and I can't find any tutorials that don't use TransformAspect.

[vapid patrol]

how would i go about making a quake style camera tilt when strafing? ive looked everywhere online cant find any working code and when i try to do it my self theres lots of problems

[red scarab]

rotate the camera's transform.rotation while moving

[vapid patrol]

yeah thats what im trying to do

but it doesnt work when i rotate on the y axis

[red scarab]

move the GameObject's transform.position

[red scarab]

post your code

[vapid patrol]

i got this code to work but when i move from left to right it doesnt smooth it

 
         Quaternion finalRot = Quaternion.Euler(xRotation, yRotation, rotZ);
         transform.localRotation = Quaternion.RotateTowards(transform.localRotation, finalRot, _rotationSpeed);
     }```

[red scarab]

when you say "smooth", you mean it's just going from level to tilted immediately?

and you want it to reach the final tilt gradually?

[vapid patrol]

lemme record a vid

[upbeat carbon]

wouldn't that defeat the point of using entities?

[red scarab]

what do you mean specifically by "entities"? entity is a very vague word that doesn't really have any meaning, so i'm assuming by entity you mean :

1. a GameObject, which
2. has been Instantiate<>() 'ed

[vapid patrol]

tilt is exaugurated so u can see it better

[red scarab]

it looks smooth to me... you mean when going from left to right, it's a very sudden jerking motion?

[vapid patrol]

when i go right and let go its ok but when i switch immediately it doesnt smooth

[vapid patrol]

no at 0:07 i start going left to right fast it isnt smooth

[upbeat carbon]

Sorry, I should have used the dots forum. I'm talking about the entities package

[red scarab]

can i see a larger code snippet? what you posted looks correct

[vapid patrol]

this is my entire cam script ``` public class PlayerCam : MonoBehaviour
{

 public float sensativityX, sensativityY;
 public Transform player;
 public Transform cameraPosition;
 public Transform orientation;

 float xRotation;
 float yRotation;

 public float _tiltAmount = 5;
 public float _rotationSpeed = 0.5f;

 void Start()
 {
     Cursor.lockState = CursorLockMode.Locked;
     Cursor.visible = false;
 }

 // Update is called once per frame
 void Update()
 {
     Tilt();
     transform.position = cameraPosition.position;

     float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensativityX;
     float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensativityY;

    
     xRotation -= mouseY;
     xRotation = Mathf.Clamp(xRotation, -90f, 90f);

     yRotation += mouseX;

     Vector3 v = transform.rotation.eulerAngles;
     transform.localRotation = Quaternion.Euler(xRotation, yRotation, v.z);
     orientation.rotation = Quaternion.Euler(0, yRotation, 0);
    
 }
 
 public void Tilt()
 {
     float rotZ = -Input.GetAxis("Horizontal") * _tiltAmount;

     Quaternion finalRot = Quaternion.Euler(xRotation, yRotation, rotZ);
     transform.localRotation = Quaternion.RotateTowards(transform.localRotation, finalRot, _rotationSpeed);
 }

}```

[red scarab]

do me a favor and edit that to include "cs" immediately following the 3 beginning tilde's (`)

just to add some color for me

@vapid patrol ^

[vapid patrol]

ok wait

colors 👍

[red scarab]

i still don't see the colors but that's okay -- it looks like at the end of your Update() function you're setting the rotation, then also setting it at the begining through Tilt()

Pretty sure that's causing the issue, based on what I can see

[vapid patrol]

 public class PlayerCam : MonoBehaviour
 {
 
     public float sensativityX, sensativityY;
     public Transform player;
     public Transform cameraPosition;
     public Transform orientation;
 
     float xRotation;
     float yRotation;
 
     public float _tiltAmount = 5;
     public float _rotationSpeed = 0.5f;
 
     void Start()
     {
         Cursor.lockState = CursorLockMode.Locked;
         Cursor.visible = false;
     }
 
     // Update is called once per frame
     void Update()
     {
         Tilt();
         transform.position = cameraPosition.position;
 
         float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensativityX;
         float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensativityY;
 
        
         xRotation -= mouseY;
         xRotation = Mathf.Clamp(xRotation, -90f, 90f);
 
         yRotation += mouseX;
 
         Vector3 v = transform.rotation.eulerAngles;
         transform.localRotation = Quaternion.Euler(xRotation, yRotation, v.z);
         orientation.rotation = Quaternion.Euler(0, yRotation, 0);
        
     }
     
     public void Tilt()
     {
         float rotZ = -Input.GetAxis("Horizontal") * _tiltAmount;
 
         Quaternion finalRot = Quaternion.Euler(xRotation, yRotation, rotZ);
         transform.localRotation = Quaternion.RotateTowards(transform.localRotation, finalRot, _rotationSpeed);
     }
   
    
 
 }```

colors?

[red scarab]

thats better lol. colors

[vapid patrol]

yay

[vapid patrol]

ill try removing it

wait should i just remove the orientation.rotation = Quaternion.Euler(0, yRotation, 0); or what

im dumb

@red scarab

@red scarab yo i just fixed it by going to inputs and disabling the snapping on the axis

it worked

thanks

u the 🐐

i made another axis for the script called HorizontalCam so i can still use snapping on my movement axis 👍

changing the speed variable does nothing tho idk why its not too bad tho

oh wait it does work but only if i set the tilt to something crazy like 90

ok i should go sleep lol

[agile lynx]

Hi guys let's see if you can help me out here

I'm making a state machine to control all my enemy characters. The state machine itself looks like this

    public class StateMachine<T> where T: Entity
    {
        public State<T> CurrentState { get; private set; }

        public void Initialize(State<T> startingState)
        {
            CurrentState = startingState;
            CurrentState.Enter();
        }

        public void ChangeState(State<T> newState)
        {
            CurrentState.Exit();
            CurrentState = newState;
            CurrentState.Enter();
        }
    }

As you might see, the CurrentState variable is generic since the state itself should be able to access the entity it is controlling.

public abstract class State<T> where T: Entity
    {
        // To be able to change the state of the entity
        protected StateMachine<T> stateMachine;

        // To be able to access the gameobject itself
        protected T entity;


        public State(T entity, StateMachine<T> stateMachine)
        {
            this.entity = entity;
            this.stateMachine = stateMachine;
        }

Both this classes' generics should inherit from Entity which is the script that is actually attached to the gameobject.

public abstract class Entity : MonoBehaviour
    {

        // Let every entity have its own state machine with its own states
        public StateMachine</*What to put here?*/> stateMachine;
    // More code... 
    }

There issue here is that every Entity requires a state machine to handle its states but StateMachine is generic over Entity so I have circular generics.

I tried passing this as the generic type of StateMachine but it requires a type known at compile-time. What's the best way to keep it as abstract as possible without having this issue?

[polar marten]

what is your big picture goal?

[agile lynx]

A generic state machine that works for every enemy entity (maybe even the player itself)

Hey guys I was trying to make something save in a scene in Unity
I have a boolean in a scene that is false
In the scene after playing some of the game, the boolean turns to true
When I leave that scene and come back the boolean is reset to false, can anyone please explain how I can make the boolean save if its true or false and it wont reset if I exit the scene?

[oblique spoke]

You can't, as you generally don't modify the scene files at runtime. You can save your changes to a different file and apply them whenever you load the scene

[pale shadow]

Would you be willing to help me make this please

So basically I would be able to save the boolean into a seperate file, and when I load the scene the boolean would be applied right?

[leaden ice]

You have to write the code to make that happen

[pale shadow]

im 100% lost on how to do the saving into the file and loading it into the seen, I have never done anything like this before and this is my first game

[oblique spoke]

Look up saving and loading systems and you should find bunch of material

[pale shadow]

ok thanks, but 1 question I would be able to save it to the file during the game is running right? the game wont have to stop to save it and load it correct?

[leaden ice]

When your game is stopped your code won't be running so that would make little sense

[oblique spoke]

Small amount of data saves and loads very quickly

[grave crane]

I was tring to use unit tests in playmode, but I need it to work after the other scripts in the scene run the awake method, is it possible?

[leaden ice]

You could just do a yield return null to wait one frame in a coroutine test for example

[gleaming sparrow]

maybe change script load order priority from the project settings? idk

[proven plume]

Hi guys let s see if you can help me out

[fast wraith]

Hah. I had to right click the incompatible assembly in the solution and reload it manually.

[fathom geode]

I have an object performing a somewhat costly check in it's update thread, but I don't actually need the script to update often (but do need it to run in the background)
basically, it's sequencing relative to other events is entirely unimportant. Is there an "async" equivalent to update I could run here, or something similar?

[gleaming sparrow]

Coroutine

[fathom geode]

wouldn't that update just as often as the main thread? or do I use waitforseconds and have the coroutine restart itself?

[gleaming sparrow]

yeah you can use a waitforseconds to delay it and let it repeat every so many seconds

[void basalt]

Pretty sure coroutines don't operate on a different thread

I've never used them, so someone else will have to verify.

[fathom geode]

they 100% do not operate on a different thread

but I think he's right in that his solution is more performant (although still on the main thread)

[void basalt]

You can write your own batch thing

one tick, check first 1/3 of items

next tick 2/3

next tick, 3/3

The problem with using threads, is that if you're not careful, you'll spend more time actually getting the data between threads, than your current bottleneck

and then you have thread safety, etc

[fathom geode]

yeah I'm aware of the risks of splitting info across threads, I was hoping due to the asynchronous nature of this specific case that it wouldn't be a problem

[void basalt]

Ensure that you're not running everything in update()

[fathom geode]

ofc

[void basalt]

Your simulation code should run in fixedupdate

along with pretty much everything important

simply use update() to interpolate and render

You also need to manage your garbage collection activity, if you're looking for performance

allocating a ton of crap every time your game updates is going to make things run slow

You should probably post the object's "costly check" here so that other people can take a look at it.

[fathom geode]

I actually fixed that specific case, it was a simple logic error, but I'm more interested in the general discussion bc I do commonly have situations where I need something to be continually updating in the background but the rate at which it updates isn't important

[void basalt]

Yeah running everything in update is a huge waste

and a lot of people do it because they're unaware of what they're doing

[fathom geode]

 if (transform.InverseTransformPoint(playerTransform.position).z > 0)
        {
            if (!hasPlayerEntered)
            {
                hasPlayerEntered = true;
                PartySceneSingleton.Instance.isPlayerInRoom = true;
            }
            
        }
        else
        {
            if (hasPlayerEntered)
            {
                hasPlayerEntered = false;
                PartySceneSingleton.Instance.isPlayerInRoom = false;
            }
        }

this was the code causing issues, I was updating the value in the singleton more than once per change, when my intention was to only do it once per change. Fixing that solved the problem

I'm not 100% sure update vs fixed update is going to matter a ton on low end hardware. Won't fixed update execute multiple times on a frame if the framerate is low?

[void basalt]

Unity's FixedUpdate only runs on render frames. There's really nothing special about it. It does, however, only run on certain render frames at a specific interval

[fathom geode]

I understand it's essential for anything involving rigidbodies but I mean I'm not sure about update vs fixedupdate as a one size fits all thing

nevermind TIL

[void basalt]

Unity's update loop is all single threaded. It all happens sequentially

        while (timer >= Time.fixedDeltaTime)
        {
            timer -= Time.fixedDeltaTime;
            Physics.Simulate(Time.fixedDeltaTime);
            FixedUpdate();
        }```

Imagine this inside of an update loop. This is how unity's fixedupdate works

To get our interpolation alpha, all you need to do is timer / time.fixedDeltaTime. This will return a value from 0 to 1 that specifies how far we are in the current tick.

We're delving into advanced territory, but you get the point.

[sly nacelle]

I need help with changing to a layer on a gameobject that effects the children

[gleaming sparrow]

U want to change layer and have all children change with it?

Does this need to happen at runtime?

[sly nacelle]

yes and yes

I have a script to change one gameobjec but I dont want to apply it to all the gameobjects

[gleaming sparrow]

Wait u do or u dont wanna apply to all children too?

Oh u mean the script

Yeah understandable

Well u could get all children of the gameobject by doing foreach (Transform child in transform) { }

This only goes 1 child deep though

So children of children arent found

[sly nacelle]

damn

this is what I have rn

if (other.gameObject.CompareTag("Light"))
{
gameObject.layer = 3;

    }

[gleaming sparrow]

Best way to get all of em is this i think:

private void ChangeChildLayers(Transform trans)
{
    foreach (Transform child in trans)
    {
        child.gameObject.layer = 3;
        ChangeChildLayers(child);
    }
}

[gleaming sparrow]

Hope this helps

[inland escarp]

Is there anyway to get around the vector3 doesn’t accept doubles thing?

[gleaming sparrow]

Edited

[sly nacelle]

oh lol

[void basalt]

(float)myDouble

[inland escarp]

Doesn’t that convert to float?

[buoyant crane]

does it need to be doubles?

[void basalt]

Vector3 only accepts float

[gleaming sparrow]

And int i think

[void basalt]

Are you doing something that requires double precision?

if not then dont

[edgy lynx]

yea most likely would never need a double really, unless idk Kerbal Space Program. 🤷

[inland escarp]

I believe so. It’s a ballistic simulation that works with small numbers and I think the lack of precision is causing it to act weird

[void basalt]

Unity's simulation only uses floats

the second your numbers get plugged back into unity, they're floats

[buoyant crane]

there’s this https://docs.unity3d.com/Packages/com.unity.mathematics@0.0/api/Unity.Mathematics.double3.html

[inland escarp]

That seems useful thank you

[buoyant crane]

can you perform the double operations on your own and then cast it to a float at the end?

[inland escarp]

Potentially. That may be a good enough solution now that I think about it. Don’t know how that slipped my mind. Thanks.

[buoyant crane]

yeah should reduce most of the imprecision

[void basalt]

You haven't passed a parameter in.

[gleaming sparrow]

You didnt pass the transform parameter

Just do ‘transform’

[sly nacelle]

I dumb

[gleaming sparrow]

🙂

Even nicer would be if u would replace ‘3’ with newLayer int as parameter that can be different whenever ChangeChildLayer is called

Then u can also make it set to other layers if u want. Maybe when u wanna change to another layer

[sly nacelle]

maybe

[buoyant crane]

i would remove the if statement in the ChangeChildLayers method, may or may not cause it to not work depending on how you set up your game.

[sly nacelle]

I did it was a mistake

it works

[gleaming sparrow]

Nice

[pale shadow]

Hey guys so I was using PlayerPrefs and basically I have the same script attached to 5 different levels of my game

And since the PlayerPrefs are not specific to one scene, they get carried over to the next level and ruin the next level

Is there a way I can make PlayerPrefs unique for each different scene so that they dont ruin each different level but still work for the level they are supposed to work for?

[buoyant crane]

use the scene index as part of the player pref key

[pale shadow]

Wait this confused me, I can show you what I have

[buoyant crane]

highscore = PlayerPrefs.GetInt("highscore" + SceneManager.GetActiveScene().buildIndex, 0) would retrieve the value from key "highscore1" if you are on scene 1 for example

[pale shadow]

OH

[pale shadow]

wait your so smart tysm

[kindred sparrow]

    [SerializeField] private Transform ui;
    [SerializeField] private GameObject title_screen_ui;
    [SerializeField] private GameObject lives_ui;
    [SerializeField] private GameObject turn_menu_ui; 
    [SerializeField] private GameObject turns_ui; 
    [SerializeField] private GameObject opponents_turn; 
    [SerializeField] private GameObject your_turn; 
    [SerializeField] private GameObject press_to_start_button; 
    [SerializeField] private Button start_game_button; 
    [SerializeField] private Button attack_button; ```

Instead of using [SerializeField] private I would like to instead have my inspector show less fields and to make the references to the children in the code directly

Assigning in the inspector is the preferred method.

But transform.Find and transform.GetChild etc should work fine, generally

[buoyant crane]

what exactly are you trying to store? the name of the collider?

[inner oar]

I've been told that assigning in the inspector takes up more performance in total though, and I'm supposed to get as much performance out of it as possible

I havent even seen what sort of command takes more or less performance to get the same task done. I was just thinking that the fewer steps there are, the less performance it would require. So it never made much sense to me that doing anything other than assigning in the inspector would take up less performance.

So my question is, is there anything that could make this more performance efficient? Or to have better code practice?

[kindred sparrow]

Yes

[leaden ice]

No idea where you heard that thing about performance. It's false

[kindred sparrow]

I want the name of the object being hit so that I can use it to change its position

[buoyant crane]

so do you want the transform of the collider then?

[kindred sparrow]

Yes

I’ve done it just fine

But it doesn’t stay on if that makes sense

[buoyant crane]

it doesn’t sound like you need to store the name, just the transform

[kindred sparrow]

Idk, I need to get the transform to happen continuously

[leaden ice]

Why do you need the name to change its position?

[kindred sparrow]

Because the object of which I’m changing is not the one containing the script

[leaden ice]

You just need a reference to the Transform

[leaden ice]

So?
