I'm having a problem with my VTOL rotation script:

Vector3 rotationTorque = new Vector3(-mouseY * mouseSensitivity, mouseX * mouseSensitivity, 0);
Vector3 currentRotation = VTOLBody.transform.eulerAngles;
currentRotation.z = 0;
VTOLBody.transform.eulerAngles = currentRotation;
rb.AddRelativeTorque(rotationTorque);

if (Input.GetKey(KeyCode.Space))
{
  rb.AddForce(Vector3.up * vtolForwardSpeed, ForceMode.Force);
}
if (Input.GetKey(KeyCode.LeftShift))
{
  rb.AddForce(-Vector3.up * vtolForwardSpeed, ForceMode.Force);
}

Vector3 moveDirection = VTOLBody.transform.forward * pitchInput + VTOLBody.transform.right * rollInput;
moveDirection.y = 0;
moveDirection.Normalize();
rb.AddForce(moveDirection * vtolHoverSpeed, ForceMode.Force);

Debug.DrawLine(VTOLBody.transform.position, VTOLBody.transform.position + VTOLBody.transform.forward * 15f, Color.blue);```

The rotation for the body stutters with the more I move the mouse. Rb is set to interpolate and this code is inside FixedUpdate(). I'm assigning mouse input inside Update()

hierarchy looks like this

[heady iris]

What is VTOLBody ? vtol in the hierarchy?

[steady mountain]

Yes

[heady iris]

Does it change if you remove the bit that sets the transform's rotation direectly?

the fourth line in that snippet of code, specifically

[steady mountain]

It does seem to improve

How else can I clamp the Z rotation?

[heady iris]

Setting the rigidbody's rotation instead of the transform's might help

[steady mountain]

Thanks, I'll try

Should I clamp it inside update() or FixedUpdate() though?

[heady iris]

I don't know how rotation gets interpolated

setting it in FixedUpdate seems like the right thing to do

(but that might wind up looking stuttery)

[celest iron]

Any Rigidbody rotation is handled in FixedUpdate, this includes Rigidbody.Rotate and Rigidbody.MoveRotation.

https://docs.unity3d.com/ScriptReference/Rigidbody.MoveRotation.html

[steady mountain]

Should I also assign mouse input inside FixedUpdate()

[celest iron]

For the new input system it doesnt matter

For the old, it will look jittery

[heady iris]

I can see some problems happening if you're reading mouse delta in Update and using it in FixedUpdate

if you get two frames before the FixedUpdate, you'll lose the first frame's deltas

so you might want to sum them up in Update and then reset the total to zero in FixedUpdate

[steady mountain]

The issue seems to be with the VTOL's range of rotation and how it indirectly results in roll in the aircraft. My stuttering was coming from my existing code trying to apply roll but the clamp wasn't doing a real-time job

Still can't figure out how to clamp it without stuttering though

Having trouble with seamless chunk alignment in my Unity terrain generator using HLSL for marching cubes. Noise offset is set based on world position, but chunks still don't align. Anyone faced this before or have suggestions for debugging?

I can share my noise generation code if anyone wants to have a look.

[heady iris]

I'd be diagnosing this by visualizing the noise coordinate. Maybe make the terrain height be just the noise coordinate's X value

[celest iron]

Are you sure you're aligning with the ends, not the middle?

By ends I mean the chunk borders

[whole portal]

Debugging right now guys. Will come back with the results, thank you very much.

Here are the logs.

[whole portal]

Vector2 noiseOffset = new Vector2(transform.position.x, transform.position.z);```
The position for each chunk and its noise offset is determined by the world position.

Should I debug this as well to make sure that's the case ?

[celest iron]

It wouldn't hurt

[heady iris]

where do you use the noise offset?

[upbeat roost]

Hello Guys,
I am working on a 2D Game and currently I want to detect some corners of a tilemap Collider. (see picture) Is this possible via code? and How? A general approach will also help.

[whole portal]

I've added debugging blue spheres which represent the corner of each chunk and its outline.

That's what I've got.

[whole portal]

The NoiseOffset is used in my GenerateNoise function in my NoiseCompute.compute HLSL shader. Specifically, it is added to the pos variable that determines the position where the noise is sampled. Here's the relevant line:

float3 pos = (id * _NoiseScale) / (_ChunkSize - 1) * _Scale + float3(_NoiseOffset.x, 0, _NoiseOffset.y);```
The NoiseOffset is meant to align the noise sampling across different chunks. Each chunk's noise is generated based on its position in the world, and NoiseOffset helps in shifting the noise function to align with that world position.

In my C# code, I set this offset based on the transform.position of each chunk:
```csharp
Vector2 noiseOffset = new Vector2(transform.position.x, transform.position.z);```
And I pass this to the shader:
```csharp
NoiseShader.SetFloats("_NoiseOffset", new float[] { noiseOffset.x, noiseOffset.y });```
So, the NoiseOffset is being used to ensure that the noise generation starts at the appropriate world coordinates for each chunk, aiming to make the noise seamless across chunks.

[heady iris]

NoiseOffset isn't affected by scale. That sounds suspicious.

although I also don't really understand what's going on in that first line in general

[whole portal]

Which one ?

[heady iris]

float3 pos = ...

id doesn't sound like a float3 to me, so that's weird

[still carbon]

Is there any way to tell what's chewing up memory in Unity? I've disabled everything in my scene - and restarted the editor so that everything was already disabled upon initial load - and the memory usage is still increasing at a pretty constant rate. If I let it sit for a day it'll go from a couple of gigabytes to north of 50.

[heady iris]

the memory profiler might be able to help here.

[heady iris]

The entire line doesn't make sense to me. I would expect to see something where you scale a local-space position so that it's at the right world scale, then add the noise offset.

(or just convert a local-space position to world-space and not even need a noise offset)

[whole portal]

In HLSL, the uint3 id provided by SV_DispatchThreadID can indeed be used in arithmetic operations with floats, but it may be a point of confusion if someone expects id to be of type float3.

The uint3 id is implicitly converted to a float3 during the arithmetic operations in the line.

• id: This is the thread ID, which ranges from 0 to (_ChunkSize - 1) in each dimension (x, y, z). It identifies the point in the chunk grid that we are currently considering.
• _NoiseScale: This scales the noise. Higher values will "zoom out" the noise, making it less detailed, whereas smaller values will "zoom in," making it more detailed.
• _ChunkSize: This is the size of the chunk in the grid. It's the number of points along each edge of the cubic chunk.
• _Scale: This scales the coordinates of the point. It's used to map the chunk grid to world coordinates.
• _NoiseOffset: This is an offset applied to align the noise function across different chunks. It ensures that the noise function starts sampling at the correct world coordinates for each chunk.

(id * _NoiseScale) / (_ChunkSize - 1): This part scales the thread ID so that it ranges from 0 to _NoiseScale, rather than 0 to (_ChunkSize - 1). The scaling depends on the chunk size and the desired noise scale.

• _Scale: Then we scale these coordinates further based on the _Scale factor.

• float3(_NoiseOffset.x, 0, _NoiseOffset.y): Finally, we add the noise offset to ensure that the noise function starts at the correct position for each chunk.

This value of pos is then used to sample the noise function.

It's a quick summary generated by GPT, so not sure how 100 accurate it is.

[heady iris]

Ah, that's the thread ID. OK.

although, I feel like you should be summarizing your code, not chatGPT...

[whole portal]

I followed a guide which only provided the foundation and I'm just adding on top of it, so not even I understand exactly how this works at the moment. What you see going on with chunk generation (And I have digging too) was added on top of that foundation.

Here is the outline of the scripts and shaders I'm using (excluding my digging script)

The chunk manager was something added by me on top in order to get infinite generation. It was not in the original guide.

[whole portal]

Also in-editor.

[winged mortar]

I think Ur talking to an AI @heady iris

As if he fed your answer into gpt

And got that answer back

[heady iris]

i would advise not using chatGPT to learn to program, for sure.

[gray mural]

Is it possible to make player select just one option here? (still gonna use Flags)

[Flags]
public enum ItemType
{
    Ground = 1,
    Wall = 2,
    Player = 4,
    Obstacle = 8
}

public ItemType collisions;

[heady iris]

it's going to wind up inventing code that's wrong in novel ways

[heady iris]

well, the player wouldn't have access to the editor GUI in the first place

so you'd be using a TMP_Dropdown or something

[winged mortar]

"In HLSL, the uint3 id provided by SV_DispatchThreadID can indeed be used in arithmetic operations with floats, but it may be a point of confusion if someone expects id to be of type float3." Who's someone?

[whole portal]

I already said I was using GPT, I just told it someone's confused about it, that's why it replied like that.

[celest iron]

I may be mistaken, but don't you need 4 offsets for one chunk?

[winged mortar]

I think it is not just limited to that one response..

[gray mural]

I am sorry, I meant developer. Is it possible for me to be able to select just one option in the inspector as if it was a non-flags enum?

[heady iris]

I think you would need a custom property drawer.

[whole portal]

I have no idea

[gray mural]

I see, that doesn't worth it then

[winged mortar]

Have you tried just adding serialize field above it?

[gray mural]

no.

[heady iris]

if you have no idea then you're going to have a VERY rough time writing a compute shader

[whole portal]

Isn't it supposed to just sample the centre of each chunk (assuming the chunks are all equal size and equally distributed) ?

[winged mortar]

I am sure I have enum dropdowns in my project, could try to find some code for it

[heady iris]

I haven't written compute shader code in a while (well, it was CUDA, but close enough), but I distinctly remember it leaving very little room for "i don't really know"

[heady iris]

That's not the issue

apple wants the dropdown without the multi-select.

[gray mural]

it's not for enum dropdown, I also have a script for EnumDropdown

[celest iron]

Well, I have absolutelly no idea how to work with shaders, but for normal terrain gen you'd need to give offset for each possible chunk neighbour

[winged mortar]

I don't think it has multi select?

Or is that added due to the flags attribute?

[gray mural]

Flags does have multi select in the Inspector

we're talking about inspector

[pastel patio]

I do know a way, basically write 2 enums, one flagged, but it's not clean, but it does function, I did it once in a project I was messing around with

[gray mural]

exactly

[winged mortar]

Alright got it, didn't know flags would add a multi select dropdown, mb

[celest iron]

See, I told ya you were probably just using the center of the chunks instead of using the borders

[gray mural]

oh, I thought you were talking about TMP_Dropdown 😅

[celest iron]

probably you forgot to add the chunk size somewhere

[pastel patio]

flags converts it to a layermask, something that looks very self explanatory if you look at it from the perspective of bytes

[whole portal]

I don't think i need to write shaders though (at least for the moment), they're already written.

[gray mural]

I see now, it's kinda the same as in LayerMask

[pastel patio]

Yep, you can make a second enum with the same names to use as a single-option selection, it makes code look worse imo but it makes inspector a tad clearer, if it's worth it it's up to you lol

[whole portal]

@celest iron I may need to use offset. Trying to see if it fixes it.

[celest iron]

Good luck

Keep in mind tho I know nothing about shaders. I'm giving answers based on what I know, which is terrain gen.

[whole portal]

No worries, anything helps.

[celest iron]

For thhe problems similar to this I've seen, most people were passing just the center of the chunk, so it wouldn't align with the borders OR passing only the final point/pixel as offsets, making it only align in the last vertex.

[pastel patio]

I've been having trouble with loaded&unloaded object compatibilities
(i) Unloaded version is just a struct with id, pos, rot, and extra data, loaded is monobehaviour based

Since a reference to another loaded gameobject can not be saved past a reset (Or call it a reload), I would have to keep the reference focused on the dataside, which is the side that always exists.

So I thought to make the data of every single object registered in a list, and all the data keeps their index in the list (public int instanceId)

However, any option I'm aware of would mess up with removing an element from the list, since any new object taking it's place after id would be mistaken by references to be the original.

Resolves I can think of so far:

Changing the structs to classes could be an option, maybe, idk if it could be destroyed and whether if it would set all references to invalid.

Another option I can think of is to make references subscribe to events that warn them about id reassignments and deletions, but I'm uncertain if this is a good idea, sounds like it could be dangerously expansive...
Unless if someone knows a whole better way to approach this problem? Sorry about making this a difficult read but I wanted to explain this problem from the bottom up.

Please ping if and when you reply, thanks!

Thank you for the advice.

hi Guys
i have a problem again
i dont know the wrong in the code
the code must show the "GAMEOVER" and restart buttom when the player collied with the Enemy but when i start the game the player got invisiable

[simple egret]

Nothing makes the player disappear here.
A common cause is that the script that makes the camera follow the player sets the camera's position to the player's position, thus putting them at the same Z position, rendering the player invisible

Make sure that when you play the game, the camera's position stays at Z -10

Or whatever you have initially in the scene

[simple egret]

Now while playing the game

[brisk grove]

oh

[scarlet viper]

would it be faster in runtime to store over thousand dictionary keys or to store just a hundred and interpolate/Lerp between them?

[rigid island]

if(gameObject == true)
{
gameObject.GetComponent<SpriteRenderer>().enabled = false;
gameObject.SetActive(true);
}

[brisk grove]

it didint worked

[rigid island]

this will always be true

[brisk grove]

and?

[rigid island]

ur setting sprite to false

so it "disappeared"

[simple egret]

Welp so big I managed to not see it

[brisk grove]

what should i do

[simple egret]

"if this object exists, make me invisible" - This is always true

[rigid island]

make a condition that makes more sense

[brisk grove]

set it true?

[simple egret]

Set it to false elsewhere

[brisk grove]

how?

[simple egret]

Probably when you enter in collision with the enemy

[rigid island]

if(gameOver == true)

why make it true on collision if ur not gonna use it

but yeah having it in update is overkill

just put it inside OnTrigger

[brisk grove]

ok i will try

 private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.CompareTag("Enemy"))
        {
            GAMEOVER = true;
        }
        if (gameObject == true)
    }

like this ?

[simple egret]

Well you only copied one line instead of the whole if statement

[brisk grove]

no

this is the whole if statmint

if (gameObject == true)

ohh

[simple egret]

No you forgot the whole block after it

[brisk grove]

yeah right

[simple egret]

The if statement is also not necessary

[brisk grove]

 private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.CompareTag("Enemy"))
        {
            GAMEOVER = true;

        }
        if (gameObject == true)
        {
            gameObject.GetComponent<SpriteRenderer>().enabled = false;
            gameObject.SetActive(true);
        }

    }

?

[simple egret]

You can put the two lines inside the if (collision.gameObject.... one

if (gameObject == true) will always be true. When the script runs on an object, it exists

Perhaps you meant GAMEOVER == true?

[brisk grove]

how
can u write it

[gray mural]

collision.CompareTag()

it's Component.CompareTag

[simple egret]

????

[gray mural]

Collider2D is a component

[brisk grove]

the gameover object must be visible when the Enemy collid with the player

[brisk grove]

and

[gray mural]

so gameObject is redundant

[brisk grove]

?

[rigid island]

bro the solution was clear #archived-code-general message

[gray mural]

so basically, it really #archived-code-general message

[brisk grove]

*I DIDINT UNDERSTAND *

[simple egret]

That's not really complex to understand, no?

[gray mural]

if (collision.gameObject.CompareTag("Enemy")) ->
if (collision.CompareTag("Enemy"))

and gameObject can never be null

gameObject == true is the same as gameObject != null

[simple egret]

You gotta step the level down a bit, they aren't ready for that

[gray mural]

the same as if (true) in your case

[brisk grove]

so i should delet gameobject

[gray mural]

I have literally written it...

to be sure, you have to delete .gameObject

and it also #archived-code-general message

[brisk grove]

private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Enemy"))

Basically it will always be true, because the comparison is between a non-null object reference and a boolean value, and the comparison is implicitly converted to true if the object reference is not null

[rigid island]

dude is just trolling at this point

[brisk grove]

no

[gray mural]

ok, so I wrote this?

[brisk grove]

no

[brisk grove]

i did

[rigid island]

this is invalid syntax

[gray mural]

I see ?

[spring creek]

I was gonna say. Something funky with those parentheses

[gray mural]

[brisk grove]

yes

[rigid island]

the parentheses? wdym

so you should correct these red waves 😄

yes, that's fair, but I'm talking about the case with a block statement

@gray muralthx evry 1

[sleek bough]

You should lookup existing solutions for this first. One of the solutions could be caching all the vertices of the collider and comparing if the collision point extremely close to one of them. Or measuring the angle of the collision.

[brisk grove]

also the button is boroke

its more fitting to what you're asking, there is also more people around to help

[brisk grove]

ok

[upbeat roost]

Thank you that helped 🙂

[modern creek]

Getting some random editor/unity NREs in 2023.2.0b8 that I didn't see before.. any idea what these could be?

[heady iris]

resetting your layout might fix it

hard to say what, exactly, is breaking

[modern creek]

yeah I thought that too, I tried.. 😦

i tried also opening/closing presets folder, trying to get unity to rebuild it

I don't have any presets in this project, I don't think

🤷‍♂️

Ah, figured it out. Closing/reopening the Tile Palette window fixed it. No idea why.

Actually, no, just .. having the window causes the issues. I'll file a bug I guess

[craggy sapphire]

hey, so i know this isn't technically unity, but i still figured i'd ask here because there's lots of c# people; is there a way to get newtonsoft json into a project without dealing with nuget?

or, is there a way to recreate nuget without visual studio code?

[heady iris]

i just use NuGet for Unity to install NuGet stuff

[craggy sapphire]

...the whole point is not using nuget

[heady iris]

you said "without Visual Studio Code"

so I thought there was something specific there

there's a unity package that installs Json.NET

[craggy sapphire]

i'm not using unity either

[heady iris]

https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@3.0/manual/index.html

[craggy sapphire]

is the thing

i kinda just needed c# help now and this was the only place i could think of

[heady iris]

do you mean without Visual Studio?

[craggy sapphire]

yeah

[heady iris]

!csharp would be more likely to know this

[tawny elk]

You can format your multiline code block with C# highlighting! Just add cs to the start of it. Highlighting example below!

class Fluffs : FluffyCat
{
    public void PetCat ()
    {
        Debug.Log ("Petting Cat.")
    }
}

[heady iris]

er

!cdisc

[sharp rose]

Hello! I'm a newbie and I'm trying to implement a cool feature where everytime the character picks up a puzzle piece it displays an animation of it in the top left corner. I have a script that adds to a counter everytime a piece is picked up, I will take any advice or show any code if asked to, I could really use some help as this is for a game jam for Uni and I have limited time.

[spring creek]

"Just add cs to the start of "it""
Lol, only helps if you do the code bot as well.

[rigid island]

or i suppose being familiar with codeblocks from markdown

[spring creek]

Is there an issue? You say you have code that does something, but is some part of it not working?

Oh, you ONLY have the part that increments the counter

[sharp rose]

yea thats it...

[rigid island]

"your multiline code block "
Like mf how do I make this ? lol

[sharp rose]

Am I taking on too complicated of a task for a beginner dev under time constraint?

[spring creek]

I don't think so. Do you have any experience with the animator?

[heady iris]

I would do this in code.

[sharp rose]

Very little, I have set up an animation though that works at the moment

it displays the UI that I want in the top left

[heady iris]

You just need to position the puzzle piece in the right spot on the screen and make it do a little spin, or whatever

[sharp rose]

The top left icon is the UI and it represents when the player has picked up one piece of the puzzle

After you pick up two pieces I want the animation to change to a different animation where the puzzle has 2 pieces

[heady iris]

Ah, okay, that's different.

did you make a sprite with two pieces, or do you want to just show two pieces side by side?

[sharp rose]

I have animations for up to 5 pieces

or sprite sheets i guess

[heady iris]

sounds like you'd want to make an animator with five states in it, one for each piece

and just do animator.Play("3 pieces")

where one of the states is named "3 pieces"

[sharp rose]

does this require a script?

[rigid island]

almost anything requires a script:P

[sharp rose]

almost

[dense estuary]

It links to an image that is in my post?

[spring creek]

It does for me

[lusty timber]

I'm having trouble displaying the velocity and speed of one my cars. the code I wrote works for one of them(currentCar=0) but doesn't work for the other(currentCar=1)

Both cars have rigid bodies and the scripts are applied to a Canvas
if needed i can provide the full code, i didnt want to flood the channel

[heady iris]

so you want the red square to be exactly centered on that gizmo?

you're just computing a size there, so I'm not really seeing where you're setting the square's position

[dense estuary]

I dont set the squares position, i dont know how.

[heady iris]

well, I don't know how the square works, so it's hard to say anything!

is the square centered on another gameobject, or is the square's pivot point on a corner?

[dense estuary]

i know how it works, it makes a grid and spawns a point in the grid. poisson disc sampling.

[dense estuary]

the squares pivot is on the corner

[heady iris]

looking at this photo again

[dense estuary]

its position isnt related to the position of the gameobject its script is assigned to, its position doesnt change when i move the object

[heady iris]

so what's even drawing the red square? is this a gizmo?

i don't know what you're doing, so it's very hard to give you advice..

[dense estuary]

yes

it represents an invisible grid

[heady iris]

okay, so you want to position the grid cell such that its center is at a certain position

and you know the size of the grid

take the position you want the center to be at

subtract half of the grid size

[dense estuary]

my issue is the grid is made using an int array, and i cant use negative values.

[heady iris]

what do you mean that it's "made using an int array"?

you're going to have to show code.

[heady iris]

It's not intuitive at all that this could possibly cause an array to wind up with a negative index

[heady iris]

i don't see how this has anything to do with offsetting the grid

this calculates the number of grid cells you need

[heady iris]

you're asking how to offset the grid so that one of its cells winds up centered on the selected object in this image, yes?

[dense estuary]

yes

sorry

here is the poisson disc sampling script: https://hastebin.com/share/wojavewoye.java

I should've done that from the beginning, sorry.

[heady iris]

you should just compute all of the points normally and then offset them as needed

generating points in the local space of a specific Transform, then converting them from local-space to world-space, would probably be useful here

[dense estuary]

How can i do that?

i think right now its generating the points in world space, how can i make it generate in local space instead?

[heady iris]

Just use transform.TransformPoint

Vector3.zero isn’t implicitly “in” a specific space

It depends on how you interpret it

If you do transform.position = Vector3.zero, you just used it as a world space position

transformA.position = transformB.TransformPoint(Vector3.zero)

this interprets it as a local space position for transformB

(i am going to bed, so I’ll have to get back to you tomorrow)

[dense estuary]

thats alright, ill probably do the same.

im seeing if i can move the points with a for loop

[heady iris]

but try generating random points in the range [0,0] to [1,1] and then seeing what happens when you use transform.TransformPoint to take them from local space to world space

see what happens as you position, rotate, and scale the object

[fresh hull]

Is it possible to do string interpolation like this?

[loud wharf]

Isn't there transform.relativePosition?

[fresh hull]

I want to inherit from this on places that may use diferent keybinds

[quartz folio]

no, you would need to parse that string yourself and implement the logic manually from the result

[fresh hull]

[noble lake]

Hi everyone. Does anyone know how to render a RenderTexture over a mesh? Have to draw a bullet decal on wall collision, but have no idea how to do it using RenderTexture even after looking into it.

[quartz folio]

Why do you need a render texture? Why not use a decal? Depending on the render pipeline you use, decals are the way

[noble lake]

It's a requirement from up basically, have to use specifically render texture, using built-in

[quartz folio]

That's bizarre as hell. Though, iirc you can just apply render textures as textures in materials, so you can just put that material on a quad

[noble lake]

So there's no way to render it directly on top of obj w/o shader, I have to create a new object for every collision?

[spring creek]

You could somewhat spoof it, and if the collisions are close together use a single quad with textures that show an increasing number of bullet holes. They wouldn't be the right spots, but...

That would require distance checking or some spatial query for each one though... so, that's suboptimal lol

[noble lake]

And if talking about bizzare things, it's a technichal assignment test, an basically I had to create a cannon with mouse control, immitate physics and collision detection w/o using any unity framework (well, almost), and procedurally generate meshes for random bullets. That's tough lol

[noble lake]

I might just instantiate a prefab with render texture on material, have no other solution for now

[whole portal]

I'm working on a terrain generation system in Unity where the terrain is divided into chunks. The terrain generates seamlessly, but I'm facing an issue when I try to "dig" or modify the terrain at the boundaries between two adjacent chunks. When I dig at the boundary, the two chunks become separated and don't align properly.

Can anyone give me a hint of what to check for ?

[whole portal]

I think I'm close to fix it, but anyway if someone gets into this issue, check these posts:
https://www.reddit.com/r/gamedev/comments/98k3ht/marching_cubes_destruct_terrain_between_chunks/

[swift falcon]

Can anyone please help me with creating a grid that doesn't render behind walls? It's really ruining my game ngl

Pleasee I beg lol
I've been stuck with this for a while and unable to find anyone to help

[quartz folio]

The grid needs to use ztesting and the walls need to write to depth.
This is more of a #archived-shaders issue than a code one though depending on how you draw the lines

[swift falcon]

I ask it here simply because I'm fine with remaking this grid if anyone has any suggestions

GL.Begin(GL.LINES);
cellMat.SetPass(0);
GL.Color(new Color(0,0,0,1f));
        
int xStart = (int)allocatedPosition.x * chunkSize;
int zStart = (int)allocatedPosition.z * chunkSize;
for (int x = 1; x < chunkSize; x++)
{
  // Line right
  GL.Vertex3(xStart,0.01f, zStart + x);
  GL.Vertex3(xStart + chunkSize,0.01f, zStart + x);
  // Line up
  GL.Vertex3(xStart + x,0.01f, zStart);
  GL.Vertex3(xStart + x,0.01f,zStart + chunkSize);
}
GL.End();```This was how this one is done

I don't know anything about shaders though so is the solution going to be writing a custom shader and using that as my material for the lines then? 😦

[quartz folio]

Does cellMat perform ztesting?

[swift falcon]

Doubt it, it's just one of the HDRP materials, let me go find it

Oh nvm it's a "GUI/Text Shader"

Is there any unity default shaders I can use for this?

I didn't think drawing some lines would be so hard tbh

Bing saved me 🙏 Praise Bing haha

@quartz folio Thanks by looking at zTesting I was able to get a shader, I've been trying to fix this for ages, much appreciated

[short walrus]

Has anyone used Astar pathfinding?

[somber nacelle]

a lot of people have
https://dontasktoask.com/

also keep in mind that a* is an algorithm, if you are referring to aron granbergs a* project asset specifically you should probably mention that

[short walrus]

yeah the thing is, i want to see if someone has had the same problems as i have, for example i have a 2D game with a map with significant size, and i want a small part of it to re-scan paths. Because scanning the whole map lags the game. Ive looked around and people said to use multiple graphs, but in code, i cant find a way to isolate the graphs and separately scan them.

i could only reference the whole pathfinding astar game object which includes the pathfinding graphs. Cant find how to define the graphs separately

[somber nacelle]

this is for that asset i mentioned, yes?

[short walrus]

i dont remember exactly where i got it from, but it's "Astar Pathfinding" or A* pathfinding yes ill keep digging to find what version exactly it is

[somber nacelle]

https://arongranberg.com/astar/docs/graphupdates.html

[short walrus]

yeah that must be it

[winged hull]

how come the elif and else blocks gets grayed out in visual studio and have no intellisense?

[somber nacelle]

because that code is not being compiled

[winged hull]

is there a way i can make them not grayed out?

[noble lake]

Possibly just comment preprocessor directives and uncomment when you're done

[knotty sun]

yes, change your target platform

[winged hull]

oh i see thanks

[alpine sapphire]

if it is for play mode, regardless of how you created it, something you can do is use unity's URP system to create an effect that will not render your grid if it is behind object using this as a base tutorial, just inverse the logic : https://www.youtube.com/watch?v=szsWx9IQVDI

[swift falcon]

That is interesting... Does URP stuff like that work if I am using HDRP though?

Tbh I might just downgrade to URP... HDRP just isn't worth it for the hastle it has been, it ends up looking worse

Thanks

[alpine sapphire]

np and good luck !

[hoary monolith]

how do you exclude the UI layer from post processing?

[winged hull]

how can i use .env for environment variables or something similar to that, so I can hide sensitive data like IP addresses from the code?

[arctic spindle]

Anyone here who managed to get an image to the clipboard? I keep getting errors when I try, I added system.drawings/forms to the unity project. "Failed to set clipboard: Requested Clipboard operation did not succeed."

[halcyon dagger]

Hey there, I'd like to create a grid for spawning players / objects

please find the examples attached.

Looking for an algorithmic approach to x number of players / objects

Any pointers? Much appreciated!

[arctic spindle]

Try chatgpt, good for things like this I think

[halcyon dagger]

ooh, nice idea, thank you

[arctic spindle]

It really depends on size tho

If you want to do it yourself

Easy approach would be to just use rows if you always have 1 or 2 in a row

if total %2 == 0, even, then it's just a for loop (total/2) CreateRow(2)
Uneven would be for loop, (total-1)/2, then at the end createrow(1) for the final row

[arctic spindle]

You can also calculate height/width pretty easily with the total tho, so also a possibility if gpt doesn't work

[halcyon dagger]

I would like to spawn up to 12 players (use case for now, potentially more later)

[short viper]

Do i need to pay unity for free games?

Please some one answer

[leaden ice]

#archived-pricing-updates-talk to discuss

[knotty sun]

why are you asking in a code channel?

[urban lintel]

im trying to set up an enemy behaviour that walks in a random direction, waits a bit, and then walks in a random direction again. I've done this in a coroutine, which im not sure if it's the best approach:

    private IEnumerator MoveRandomCoroutine()
    {
        Vector2 randomDirection;
        while (true)
        {
            float x = Random.Range(-1f, 1f);
            float y = Random.Range(-1f, 1f);
            randomDirection = new Vector2(x, y).normalized;
            movement = randomDirection;
            //wait for 2 seconds
            yield return new WaitForSeconds(1);
            movement = Vector2.zero;
            yield return new WaitForSeconds(2f);

        }
    }

Now i'm trying to extend the script so that if a player is in radius, it uses a different movement (walks towards the player for example). I've already written some code for detecting whether the player is in the enemy's radius, but struggling a bit to get it to switch between this Coroutine and the simple chasing movement. Should i just extract this out of a coroutine and handle the pauses with some normal timers in the Update loop? Or are coroutines fine and i should just pause one and start the other

[main shuttle]

I think you should invest some time in learning State Machines, this one for example. It's one of the easier ways to make an AI. Just make an Idle, Chase, Patrol and perhaps Attack state, and switch depending on your condition.

[urban lintel]

will do, thanks!

[worthy jungle]

hello friends, I want to instantiate an UI image. I do that and and I set the canvas as the parent. it shows the imapge correct but the problem is scale! because it instantiates in the world first then it goes under canvas. how to solve this?

[leaden ice]

Instantiate directly as a child of thje canvas instead of parenting it after

Instantiate(thePrefab, theCanvas.transform);```

[worthy jungle]

I tried this but didnt work

[leaden ice]

wdym by "didn't work"

what happens

[worthy jungle]

it just instantiates it in the middle of the canvas position not under teh canvas really

[leaden ice]

how did you set up the anchors etc?

[worthy jungle]

exactly likeyou wrote

[worthy jungle]

that is not the problem, only teh scale is problem

[leaden ice]

what I wwrote has nothing to do with how the anchor presets etc are set up

That would be in the inspector for your prefab's RectTransform

[celest iron]

Hi.
So I have a code that generates an island using noise and a seed, so far so good. I also have an UI button that calls the method to generate the island when I click on it so that I don't need to exit game mode when I want to change values for the generation.
The problem comes when I add a seed to the world gen: if I give the seed normally, outside of play mode, it work as intended. But once I give it (the same seed) on play mode and use the button to re-gen everything, I get very weird results.
The first image is when I give the seed outside of gamemode, the second is with the same seed, but using the button to regen the world. Because the land itself is the same, the problem is with the water tile I presume.
The water tile code: https://pastebin.com/nZG4CwqA
The island gen code: https://pastebin.com/h3z3gYWD

[worthy jungle]

yeah sorry, The anchor is in the middle of the canvas as well.

[leaden ice]

what?

where do you want it to be relative to the canvas, and where is it actually appearing?

and what are your RectTransform settings

[worthy jungle]

none of these are problem, the position is not important for me, I just need that prefab to instantiate under the canvas, see. I made a UI image under that canvas, ok? then I prefab that and now I want to instantiate it. the only problem is the image scale. it changes if it is out of canvas. even if you bring it back somehow

[leaden ice]

scale is completely unimportant for UI elements

what matters is the RectTransform size

which is controlled by the anchors/offsets etc in the RectTransform

the scale you can ignore and should let the canvas scaler do its thing

[worthy jungle]

hmm, ok let me try, thanks for the help!

[rigid island]

[jovial moon]

Oh I am sorry. I intended to remove the #💻┃code-beginner one instead!

Sorry about that ^^

[celest iron]

Anyone?

[night harness]

Don’t know the best way to ask this since it’s more theory based but anyone have insight into when you want to use scriptableobjects as the base of a data system but said system also has a unique class and/or script per scriptableobject? I have a few systems where SO’s fit the bill perfectly but I also have PlayerSkills, LevelChallenges and Equipment which all have a lot of reusable data where scriptableobjects work but I have to instantiate a specified type that’s specificed in the scriptableobject.

This in all would be gross but fine but lets say I wanted to have values in said unique scripts be in an inspector so I can easily tweak them. Now I’d be looking at a new scriptableobject type per scriptableobject just so i can manually specify these unique values

Im less looking for a specific answer and more vibes from people who have had to deal with thid

[latent latch]

Usually for scripts with a bunch of different assets I've a similar amount of scriptable objects that have a similar hierarchy for each type.

[night harness]

me too but in these scenarios every object in this type has unique data. They all still share some similar traits, enough to where I’d still wanna keep trying to use scriptableobjects for this but it just seems really gross to make a whole new scriptableobject type just so I can make 1 scriptableobject of said type

[latent latch]

Probably want to clarify what you're trying to create here

[crystal birch]

Ive heard of making the seed equal to the current time of the computer was a thing lol

Or something like that

[latent latch]

Have you tried printing out a log of coordinates for each map and comparing them? Check if the values are correct in case something may be funky going on with the math funcs.

[night harness]

it’s come up a few times but lets say my LevelChallenges

Level starts with x amount of them loaded and they all contain similar data like

ChallengeName
ChallengeType
ChallengeIcon
ChallengeDifficulty
ChallengeReward

Etc etc. and the way i track and load them is perfect for SOs. But the issue is each Challenge also has wildly unique code that needs to run during the level to actually track how these challenges are going. Which means 1 script and/or class per SO. But then if I wanted some of these unique things to have inspector tweakable variables then I can’t really do that in it’s SO because they are unique to each Challenge

[latent latch]

So give me some ideas what level 1 and level 2 would have differently from each other

because at this point you can do more of a composition approach if you're having problems trying to encapsulate more data

[night harness]

I’d be curious to hear more on this

[latent latch]

meaning, just have what can be available between all levels on this script, if it's not to be used then simply ignore or hide it.

[night harness]

Basically imagine little built in mods that affect the level. From a design perspective they can do a lot of various stuff that is very unique per challenge.

[latent latch]

there could be inconsistencies between some logic, but that's up to handling via checking, or simply dont append it together on the SO

[night harness]

Seems a little gross but maybe the lesser of two evils if im picking from that and making a scriptableobject class per challenge

[worthy jungle]

I found an easy solution. after I instantiated that UI element and put that under canvas, I just got the rect transform component and changed the scale to 1 !

[night harness]

just in abit of a weird middleground where half the object works perfect for SO’s and the other half really really does not haha

[latent latch]

in the same sense it's up to the programmer to make sure the data is set correctly. I do similar stuff with my ability controller and even though I can make my fireball have some functionality which it shouldn't (richocheting) I just don't add it to it ;)

of course you do run in those corner cases which you do have to check, or add priorities

[celest iron]

The problem isn't the seed or the math, as it works, except when I use the UI button

[latent latch]

Eh, have you tested it in playmode without a button such that it renders after an amount of seconds?

[gray mural]

I want to implement a type for every ItemController and types that it can collide with.
So e.g. an enemy can collide with ground and wall

[Flags]
public enum ItemType
{
    Ground = 1,
    Wall = 2,
    Player = 4,
    Obstacle = 8
}

public ItemType itemType;
public ItemType collisions;

Do I have to make it as a Flags enum even though just 1 option in itemType has to be selected in the Inspector?
Or should it be smth else? I will then have to get ItemController's collisions and check if another ItemController can be placed on 1 square with it

[latent latch]

So, you don't want it as a flag enum because you don't want to multi select it in the editor, but you want it as a bitfield to do collision checking?

if that's the case you can probably change it via onvalidate

[gray mural]

well, I think it's probably not problem if I will select just 1 option, right?

I'm actually wondering if it's ok to use an enum in this case?

I haven't ever worked with flags enum before

is it comfortable to get multiple items from it? actually to enumerate though them

[latent latch]

the idea of a bitfield is figure out what's selected in one bitwise operation

opposed to iterating over the values

[gray mural]

I see, so & and | are commonly used with flags enums?

[latent latch]

right, im a little rusty with the stuff so I can't give the full details, but you're usually using them for when you need to know what you can/cannot collide with in a O(1) operation

[gray mural]

if ((myEnum & MyEnum.Smth) != 0)

this one?

[latent latch]

Yeah, that looks about right

[gray mural]

checking if myEnum contains MyEnum.Smth value I guess

if ((myEnum & MyEnum.Smth) == 0)

and this is "doesn't contain"

now I see, thank you, @latent latch

[latent latch]

You can also set your fields such as:

[Flags]
public enum AbilityTypeFlags
{
  Damage = 1 << 1,
  AbilitySpeed = 1 << 2,
  Chain = 1 << 3,
  Pierce = 1 << 4,
  Radius = 1 << 5,
}```

[quartz folio]

You should start at 1 << 0

[latent latch]

isnt 1<<0 all none

[gray mural]

yes, it's 1 * 2^0

so it's 1

[jovial nymph]

what could be the problem

[gray mural]

• 1 << 0 = 1 * 2^0 = 1
• 1 << 1 = 1 * 2^1 = 2
• 1 << 2 = 1 * 2^2 = 4

I think just 1, 2, 4 looks better

[latent latch]

It's just when you get into higher values

[gray mural]

you should configure your !ide

[tawny elk]

[gray mural]

yes, probably

[jovial nymph]

[gray mural]

[jovial nymph]

my bad

[gray mural]

you did smth wrong

is this script a part of your project?

oh, lemme answer you, no it's not

it throws an error in weapon sway script

those scripts have to have 1 class that matches their names

so you have to name your class weapon sway

but it's impossible

that's why you have to google c# naming conventions

guys can i do something like this

[neon plank]

Is aliveParticleCount reliable? I mean, can't the particle system create more particles when reach 0 after X time? In that case, the system would still be active but with no particles

[spark flower]

basicly 2 separate variables in one stream?

[neon plank]

Or maybe the VisualEffects's graph is never sleeping? 🤔
I don't know how to use it, I'm just asked to execute some callback after it finalized.

[latent latch]

Better posting in #✨┃vfx-and-particles as this issue has appeared a few times. I'm not too sure if I've seen it resolved, but it's iffy because of the asynchronous operations, and getting the exact information you need back isn't always exact.

[neon plank]

ok

Thanks

[fiery marsh]

Bye unity

[simple egret]

You could, but with this you need a way to deserialize. Unless items.Length always has the same value, you wouldn't know where the first array stops. So you have a few options

1. Use another serializer, like JSON ones. BinaryFormatter has security vulnerabilities and should not be used after all.
2. Write the array's length before the array itself, so you know how much to read and deserialize.
3. Write to two different files (and optionally compress them to zip, easily doable with streams and the stuff in System.IO.Compression)

I mean point 2 wouldn't work anyway, I don't think BF will like not seeing the end of stream after it deserialized the first payload

[spark flower]

thanks for the suggestion, but i just made a class that holds the nececery variables and just serialize that, so its a single now

[scarlet viper]

How to convert that to a more safe version? I feel this wont always keep other axes properly

 lower.forward = (target - source).normalized;

And im rotating only one axis anyway.
Can i somehow rotate just one axis with a direction ?

[leaden ice]

project your vector on a plane

any good HC framework ?

[leaden ice]

HC?

[limpid owl]

i've asked a question but got no answers last time

here

[leaden ice]

Sounds more like a monetization strategy than a style of game

ah ok tycoon park game is more descriptive

[limpid owl]

yeah

we have a proprietary solution for monetization

[whole portal]

public class MoveController : MonoBehaviour
{
    // ... (other variables)
    private Animator animator;

    void Update()
    {
        // Ground check
        if (characterController.isGrounded && velocity.y < 0)
        {
            velocity.y = -2f;
        }

        // Movement input
        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");

        // Initialize animation booleans
        bool isStandingJumping = false; // New animation boolean

        // Check for movement
        if (x != 0 || z != 0)
        {
            // ... (handle walking, running, and moving jump)
        }
        else
        {
            // Handle Jumping while standing
            if (Input.GetButton("Jump") && characterController.isGrounded)
            {
                isStandingJumping = true;
                velocity.y = Mathf.Sqrt(jumpSpeed * -2f * gravity);
            }
        }

        // Apply gravity and move
        velocity.y += gravity * Time.deltaTime;
        characterController.Move(velocity * Time.deltaTime);

        // Set animation states
        animator.SetBool("isStandingJumping", isStandingJumping); // New animation state
        animator.SetBool("isIdling", !isStandingJumping); // Modified to consider new state
    }
}```

I have this issue with my code where the jumping animation won't fully play, if anyone can have a look and let me know why that is.

In the video I show the settings for my animator controller.

[leaden ice]

You're setting the bool to false every frame except when you press the button

Also if you actually select the object with the animator you can watch the state machine in real time

[whole portal]

Thank you very much. So do I need to modify the code or do something in the animator ? I know some things are supposed to be controlled by the animator only. Ideally, I'd like the animation to work like this:

• Spacebar needs to be held down, as soon as you release the spacebar (no matter how fast), the jump action / animation is canceled.
• While spacebar is held, I would like a bit of delay before the character actually propels up, so that it appears that it takes momentum to jump (just like in real life, people don't instantly jump up, muscles need to contract first, body needs to prepare).
• Then the character jumps up (ideally a variable which I can play with would be perfect, so that I can make sure the jumping action actually happens when the animation is ready for it).
• If the player keeps the spacebar pressed, the animation would play in its entirety and then the character would come back to the ground, but will not jump again unless the spacebar key is released and held down again.

So I was wondering if I should set all this up in code (and how to do it or go about it) or if I should do something in the animator too.

@leaden ice

Also, your advice fixed the animation thank you, it's now function correctly but I'm wondering how to go about what I described next.

Basically exactly like this

I'll try to see if I can use a delay to achieve the same result.

[modern creek]

I have a mesh renderer with 2 materials on it. How do I remove one with Renderer.materials? I'm doing this, but it's leaving one on the renderer:

Renderer renderer = ...;
Material[] newMaterialArray = renderer.materials.Where(x => x.name != removeMaterial.name).ToArray();
renderer.materials = newMaterialArray;

Docs say something about destroying the material after?

or do the docs mean that I should be using SetMaterials() instead of materials = ...

oh, nevermind, SetMaterials doesn't appear until 2022.. i'm using 2021

[minor pike]

so i recently wrote a python script for installing a package. and it's very efficient too in terms of resource usage if i say so myself. but for some reason it also uninstalls the file right after. and the cycle happens like 500 times. any idea how to fix this?

import subprocess
import multiprocessing

def install_and_uninstall(install_exe, uninstall_exe):
    try:
        subprocess.run([install_exe], check=True)
        print("Installation successful!")
    except subprocess.CalledProcessError:
        print("Installation failed.")

    try:
        subprocess.run([uninstall_exe], check=True)
        print("Uninstallation successful!")
    except subprocess.CalledProcessError:
        print("Uninstallation failed.")

if __name__ == "__main__":
    install_exe = 'install.exe'
    uninstall_exe = 'unins000.exe'
    pool = multiprocessing.Pool()
    num_runs = 500
    results = [pool.apply_async(install_and_uninstall, (install_exe, uninstall_exe)) for _ in range(num_runs)]
    pool.close()
    pool.join()

[dusk apex]

Maybe you've got the wrong server. This channel is for Unity general coding.

[minor pike]

nah i'm at the right place i think. after all, it's a unity game

i didn't want to click on the installer myself, and wanted to do it with a python script

[dusk apex]

This isn't related to Unity, it's Editor or game development at all. Good luck.

[minor pike]

just imagine it to be related

¯_(ツ)_/¯

[soft shard]

I have not used them myself, though maybe you could try animation events: https://docs.unity3d.com/Manual/script-AnimationWindowEvent.html - you could also look up tutorials on YouTube for better examples on how to use them and set them up

From your code above, it looks like your using the old Input class, so you could alternatively use GetButtonDown and store a variable of Time.time (https://docs.unity3d.com/ScriptReference/Time-time.html), and GetButtonUp to know when it is released to handle a "cancel" condition - you could then use that timed variable to know how long GetButton has been held for, and based on that, decide how long to delay executing your jump logic (which is similar to what an animation event could do for you as an alternative approach)

For handling jump itself, im not too familiar with the CharacterController (I often use a rigidbody + capsule collider for characters), though I imagine you could do something similar to a rigidbody approach, since gravity and jumping in most cases use the same y axis regardless of component: https://gamedevbeginner.com/how-to-jump-in-unity-with-or-without-physics/ - and if you use GetButtonDown, then you have a chance in your code to know when a jump started, and can use that to prevent your last concern of instantly jumping while still holding the key down after a full jump has completed, you could even setup a bool and either unset that bool with a animation event on the last frame, or when "is grounded" becomes true again - and there may be other alternatives for your use-case, though these are first that come to mind, assuming I am understanding your scenario correctly

[whole portal]

Thank you so much for the advice, it's very helpful!

[dark kindle]

would it be possible to store voxel rotation in 3 bits instead of 1 byte or more? for example 3 bits has a combination of 8 i think, which is more than 6 different sides.

left, right, up, down, front and back

[leaden ice]

Yes

[dark kindle]

Thank

[unkempt sail]

does anyone know how to map an array of objects based on indices recorded in another array

I am trying to serialize a deck of cards with a specific shuffle then reload said serialization

cards have a var called index for each card to know where it should be in the list

and I record these indices into a list, cardListIndices

I thought this would work but it doesn't```cs
for (var i = 0; i < Cards.Count; i++)
{
(Cards[cardListIndexes[i]], Cards[i]) = (Cards[i], Cards[cardListIndexes[i]]);

}``` ps. Cards is ordered according to their indices

[somber nacelle]

why not just .Sort using the index variable as the object being compared?

[unkempt sail]

let me try that

like this Cards = Cards.OrderBy(c => cardListIndexes[c.Index.Value]).ToList();?

[somber nacelle]

sure, or if Cards is a List then just use the Sort method

actually that wouldn't be correct anyway

if you were to use OrderBy it would just be Cards = Cards.OrderBy(c => c.Index.Value).ToList();

[unkempt sail]

well thats just sorting it from 0 to 52

aka an ordered deck of cards

[somber nacelle]

is that not what you wanted? you wanted to sort by the index contained in each card object, no?

[unkempt sail]

no, I want the card list to be sorted based on the indices of cardListIndexes

[somber nacelle]

and cardListIndexes serves what purpose?

because it sounds like you are way overcomplicating this

[unkempt sail]

well I want to keep the deck shuffled in the exact order

[somber nacelle]

okay so you store the index that the card should be at. is that not what you are doing?

why do you need to store an array of indices on each card?

[unkempt sail]

Look what I am actually trying to do is make a card game

It's online, so I need all the clients to have the exact same shuffle as the server shuffled them

[somber nacelle]

and that still doesn't answer why you need to store an array of indices on each card

[unkempt sail]

Because then I can map the card list based on their indices

If you have a better solution I am happy to hear it

[somber nacelle]

that still doesn't answer why you need an array of indices on each card. why not just store the card's current index directly on the card? then you use that like i showed you before

[spring creek]

Shuffle deck, give card current index... done. It will have the same order for each player

[lean sail]

from the description "var called index for each card" it sounds like they do store it... unless im misunderstanding

[unkempt sail]

Yes exactly that

[lean sail]

and you have an array of indices to represent what should be the index, this part does not make sense

[unkempt sail]

each card has a the index where it was originally placed, like if you have bought a brand new deck, aka the order in which it was instantiated in

[somber nacelle]

they don't store the current index of the card on the card. they store the index they access it at in that other array. where that other array has the current index for some unknown reason

[unkempt sail]

Look honestly at this point I am lost to my own solution

[somber nacelle]

yeah that's pretty clear

[lean sail]

Yea i truly dont understand what Cards[cardListIndexes[i]] is supposed to do, so i assume you dont understand that part either

i mean syntatically i understand it, but logically doesnt make sense

[unkempt sail]

I have been trying to do this for like 3 hours now

[lean sail]

you might have an easier time doing this on a smaller sample (like 5 cards). at least then you can go step by step and see why your solution doesnt exactly make sense

[unkempt sail]

This is how I imagined aka sloppily wrote down how'd it would work

So I have a list of cards, (1, 7 , 10), indices are (1, 2, 3), I generate a list of random indices (3, 1, 2)

The card of the new shuffle is 10, I take the index of the current card (10), then slap it at the start of the card list

Then I guess I actually don't need to store where the card should be

[lean sail]

did you run through how this example would actually work?
You have a random list of indices, you want these to be your new card order. Also lets just say its 0, 1, 2 and 2, 0, 1 cause index starts at 0
For loop happens:

i = 0, cardListIndex[i] = 2
Cards[2] = Cards[0]
Cards[0] = Cards[2]
You now have (10, 7, 1)

i = 1, cardListIndex[i] = 0
Cards[1] = Cards[0]
Cards[0] = Cards[1]
You now have (7, 10, 1)

i = 2, cardListIndex[i] = 1
Cards[2] = Cards[1]
Cards[1] = Cards[2]
You now have (7, 1, 10)

Does this align with what you want? Hopefully i didnt typo anywhere there, wrote this pretty quickly

[unkempt sail]

pretty much

[lean sail]

If that aligns with what you want, then whats wrong?

(7, 1, 10) also does not seem like the correct result for what it should be

[unkempt sail]

if the index list says (2,0,1) then the result should be (7,1,10)

[lean sail]

🤷‍♂️ then your algorithm works if thats intended, i dont see how this would be intended though

[unkempt sail]

Means that I need a goods night sleep

Anyone have any idea why the delayedObjects field isn't appearing in inspector?

            starter.DelayedStart();
        }
    }
}```

[mellow sigil]

Interfaces aren't serializable

[torn eagle]

That would make sense lol

What would be the easiest way to handle this then? Take in behaviours then cast?

[latent latch]

There's some plugins around but honestly I've kinda abandoned that idea

casting should be fine if you want to manage that, but replacing larger interfaces I think I've had to abstract a bit more

[tame spruce]

This doesn't really fall into any channel category, I'll try asking it here. On Windows, when you navigate a menu (such as the project folders/files window) with arrow keys, you can press CTRL + Right Arrow to recursively collapse and CTRL + Left Arrow to recursively uncollapse child folders. The same worked in the Inspector. If you did the same on a serialised List, all the child elements would get effected.

The same works when navigating folders on Mac OS, however, it doesn't work in the inspector. Anyone know a workaround for this? It is an immensely useful feature.

In the image I'm posting, if on windows if you did CTRL + Left Arrow, it recursively uncollapses "Levelable Upgrade Levels", Element 0 and Element 1.

And if you do CTRL + Right arrow, on Windows, it recursively collapses all the elements and child elements so everything is visible.

[somber nacelle]

this is a code channel, mate. #💻┃unity-talk for things that don't fit in any other channel

[main shuttle]

#💻┃unity-talk is the catch all for problems that don't fall into any channel.
Afaik it's cntr+left click, or alt+left click to open everything, you can try that.

[tame spruce]

Okay, I'll post there, thanks. But what you suggested doesn't work sadly. It just highlights the element and doesn't collapse or uncollapse.

[main shuttle]

Then perhaps right click your blue Levelable Upgrade Levels and then Expand All or something like that. I'm quite sure its possible.

[tame spruce]

Right click menu has these only 😦

[tame spruce]

By the way, this works on folders both in Finder and in Unity Project Window, but it won't work in the Inspector. I'm starting to believe the same functionality just doesn't exist on Mac for the Inspector.

[main shuttle]

Would be weird to be honest, I would expect the same functionality between Windows and Mac. But I'm not at home so can't check it, but I'm quite sure that I can fully collapse and expand lists in the inspector on Windows.

[tame spruce]

I can't seem to get any traction in the #💻┃unity-talk channel. Could you please try and let me know when you have the chance?

[main shuttle]

Yeah, the trolls keep spamming about pricing... I will check in ~30 minutes, if I remember.

[tame spruce]

Thank you very much!

[marsh wadi]

I'm trying to put a breakpoint in UnityEngine.UI's EventSystem.cs; I've made unity generate the csproj files etc, I can see the source code, I can step through the source code, but breakpoints remain evasive

I've tried regenerating projects, removing .vs/obj/library folders and csproj files, building the project.. Any ideas?

[main shuttle]

Yeah it also doesn't work for me, sorry. I probably made a custom inspector for the list then, but that was years ago.
Doesn't seem to be default in Unity.

[tame spruce]

Well, thank you regardless. I'll look into something custom myself, I'm soooo used to it! (Or I'll stop having giant lists, we'll see)

Hello I have this code right now used to fade in and out of a vignette post process but for some reason the second coroutine doesn't do the effect what could be the problem?

    float maxIntensity = .4f; // max intensity

    float counter = 0f;

    //Set Values depending on if fadeIn or fadeOut
    float a, b;

    if (fadeIn)
    {
        a = minIntensity;

    }

    float currentIntensity = vignette.intensity.value;
    Debug.Log(a);

    while (counter < fadeDuration)
    {
        counter += Time.deltaTime;

        vignette.intensity.value = Mathf.Lerp(a, b, counter / fadeDuration);

        yield return null;
       

[forest ravine]

You are starting multiple coroutines and probably overlapping their effects so that your color remains in its initial state

Check if you have already a coroutine going on and if so, either cancel and restart or not start any more

[orchid bane]

Which data struct won't get a new entrance of the same value if I try to add it?

[hoary monolith]

actually, it is not remaining in the initial state, it is stuck at the end of the first coroutine

the value of the intensity is what i meant

[forest ravine]

In between which lines?

[hoary monolith]

oh wait i see what you're talking about let me check

[forest ravine]

Sorry, could you rephrase?

[orchid bane]

ds.add(5) => ok
ds.add(5) => ok but still only 1 value inside

[forest ravine]

I like to make a Coroutine field and then check if it's not null and then set it to null at the end of the call

[civic verge]

hello
I have a camera script to move and rotate my camera (Im making a city building game)
The problem is when I rotate my camera and move it forward it doesn't go forward in the direction im rotated in
can anyone help?

[forest ravine]

But would you like this behaviour?

ds.add(5)
ds.add(6)
// Now has 2 elements

[orchid bane]

Yep

[forest ravine]

Congratulations

You now will attain the power of

Hashset<T>

Good?

[orchid bane]

Yep! Thanks

[forest ravine]

Yay!

[hoary monolith]

thank you for this btw, i did have multiple coroutines running so they were overlapping for a millisecond and then suddenly stopping coroutines that are still not done with the fade effect made it look that it was stuck after doing the first coroutine

[forest ravine]

Wow, I spotted it first try, how nice you were able to solve your problem

[sharp acorn]

What is CG.Alloc and why does it take like 60ms each time I instantiate something?

I changed some stuff since then but, it was working fine 10 minutes ago

[main shuttle]

Well GC is the garbage collector of C#, if it slows you down, you usually generate huge amounts of garbage.
That can either be by cleaning up or allocating resources. So I don't know what kind of object you instantiate, but there is something wrong with it I think. 60ms is an insane amount.

[loud wharf]

You can make a property attribute that restricts the input type to certain types.

In fact, i alr made one. :p

[loud wharf]

The thing is tho, ur not actually serialising the interface, ur just restricting the input field to a type.
So gonna have to do this:
[Restrict(Restriction = typeof(IDelayStart))] public Monobehaviour[] delayObjects;
You'll have to cast it each time u use it.

Or more preferably... (For me)

public struct SerialisedIDelayStart {
  [Restrict(Restriction = typeof(IDelayStart)), SerializedField] private Monobehaviour[] _delayObjects;
  public IDelayStart DelayObj { get => (IDelayStart )_delayObjects; set => _delayObjects = (Monobehaviour)value; }
}

In this case, I basically just made a wrapper. So everytime i try to access it, it already casts it for me.

Here's the restrict attribute i made. :p
Just paste it in somewhere.

[sharp acorn]

On the profile, the instantiate "methods (?)" have got some CG.Alloc in them. Does that mean that those CG.Alloc that came after instantiate are garbage "disposal" instead of allocation?

I'm still drawing blanks as to what it could be, but that would at least help me narrow down the possible causes (once I find them xD)

Still, how does it take way more time to dispose of the memory than to allocate?

Or rather, why is it disposing of that much more memory

[main shuttle]

Can you show the script?
What you could be doing is for example make a dictionary in a for loop that all get GC.Alloc'd and the frame after the garbage collector sees there are no references to the dictionaries anymore and it removes all the garbage.

[quartz vessel]

Can anyone tell me how can i use dynamic string portion in button event function assigning

[sharp acorn]

Uff it's a bit spagetti but I'll try to illustrate you how the stack trace would look like

[knotty sun]

Say you want to pass a string parameter from the button. In your script make a method
public void OnClick(string myString) { }
Then you should be able to assign that method in the Button OnClick event handler and define a value for the string

[quartz vessel]

Not actually , i just want to know about dynamic string portion. What is this for? For example if you have a function with parameters and you go to button onclick then if you choose that function name from dynamic string portion then inspector will not ask you to add values of parameters. This is quit interesting , thats why i am asking

[solid mountain]

I want to add bullets my player instantiates to a list so I can randomly access one if them and change a public value

How can I do that, add an instantiated object to a list

[knotty sun]

List<GameObject> myList = new();
...
GameObject go = Instantiate(prefab);
myList.Add(go);

[leaden ice]

What Steve said but I would recommend directly using your script type instead of GameObject

[knotty sun]

I was trying not to completely spoon feed

[leaden ice]

e.g.

[SerializeField] Bullet bulletPrefab;
List<Bullet> bullets = new();

void SpawnBullet() {
  Bullet newBullet = Instantiate(bulletPrefab);
  bullets.Add(newBullet);
}```

[solid mountain]

Ok I get what happened

I forgot to set the list to new()

So it errored me

[leaden ice]

If you're encountering specific errors with your solution, best to just share your code and the error you're getting

[solid mountain]

It actually didn't error, but it didn't work

It seemed like it was skipping code

[leaden ice]

you would have gotten a NullReferenceException

which is an error

[solid mountain]

I'll check again and see if it works now

[knotty sun]

A NRE will cause your code to skip lines

[solid mountain]

Then maybe I just didn't see the null reference. Thanks!

[knotty sun]

This is why we use the debugger, it will be the best well spent hour of your life if you learned to use it as well

[solid mountain]

Well, I know how to use the console and debug.log, but maybe it's time to learn that too?

[knotty sun]

absolutely

It will save you hours and hours of unnecessary grief and aggravation

[solid mountain]

I hope it does lol

Because I already got some

[knotty sun]

I guarantee you, it will

            StartCoroutine(nameof(StopFiringCoroutine));
        }
    }

private IEnumerator StopFiringCoroutine() {
        while (firing)
        {
            firing = false;
            yield return new WaitForEndOfFrame();
        }
        StopFiring();
    }```

It's obvious to me that firing is continuosly switching between tru and false but idk what to do

[dusk apex]

That while loop only happens once.

You're immediately setting it back to false.

[orchid bane]

Oh, right

[dusk apex]

And next frame firing is likely set back to true
..
Repeat

[orchid bane]

Any ideas how to fix it?

[dusk apex]

What should it do?

I was just looking at the logic and not really at the question 😅

[orchid bane]

Shoot(Vec3) is called in update by player if fire button is pressed. I want the weapon to automatically turn off if there was no input this frame

[dusk apex]

if fire button pressed
    Shoot
else
    Stop Shooting ```

What input system?

[orchid bane]

It works on events from input so the method isn't called if the button isn't pressed

[dusk apex]

So the new input system or some event based system right?

[orchid bane]

Yes

[dusk apex]

Alright thus why you're trying to handle stop procedurally

[orchid bane]

Yep

[dusk apex]

done = false
if firing
    Update Target
else
    ...``````cs
while firing
    if done
        firing = false
    done = true
    yield```Something like this.. maybe
Edited

If the button was pressed, we'd set done to false and fire. At the end frame we set done to true. Next frame if done isn't set to true again ie shooting, we'll disable it.

[orchid bane]

public void Shoot(Vector3 pos) {
        fireRequested = true;
        if(firing) UpdateTarget(pos);
        else
        {
            firing = true;
            StartFiring(pos);
            StartCoroutine(nameof(StopFiringCoroutine));
        }
    }

private IEnumerator StopFiringCoroutine() {
        while (fireRequested)
        {
            fireRequested = false;
            yield return new WaitForEndOfFrame();
        }

        firing = false;
        StopFiring();
    }```
Works👍🏻

Tho stopping is now called every frame for some reason

[dusk apex]

Hmmm, stopping as in "StopFiring"?

[orchid bane]

Yes

[dusk apex]

That would only happen if fire requested was false and not set back to true

[orchid bane]

Put a debug log into the while loop, it's called the same count of times as the debug log in stop firing

[dusk apex]

Was shoot called every frame?

[orchid bane]

Let's check

[dusk apex]

I'm assuming the event system isn't skipping frames

Yeah, place a log there as well

You should see a pattern A B A B ...

[orchid bane]

Called each frame

[dusk apex]

Place a log before firing is set to false

So there ought to be a log in shoot, the while loop and below the while loop

[orchid bane]

Already placed, again, called each frame

[orchid bane]

There are, the same numbers of calls

[dusk apex]

What's the pattern? Are all three called?

[orchid bane]

Yep

private IEnumerator StopFiringCoroutine() {
        while (fireRequested)
        {
            print("falsing");
            fireRequested = false;
            yield return new WaitForEndOfFrame();
        }

        print("stopping");
        firing = false;
        StopFiring();
    }```

[dusk apex]

What does shoot look like?

[orchid bane]

public void Shoot(Vector3 pos) {
        fireRequested = true;
        print($"shoot request: {Time.time}");
        if(firing) UpdateTarget(pos);
        else
        {
            firing = true;
            StartFiring(pos);
            StartCoroutine(nameof(StopFiringCoroutine));
        }
    }```

Stopping happens on the same frame with starting

These are Time.time

[dusk apex]

Change that yield statement

[orchid bane]

To what

[dusk apex]

Since the routine starts immediately and gets to the yield.. at the end of this frame it'll continue again

False occurs and the while loop will break before the next frame

When you start a coroutine it occurs immediately

The yield only waits till the end of this frame

[orchid bane]

I don't understand

We are in Update

Why is it called immediately

[dusk apex]

That's how coroutines work.

Maybe a regular yield null before the while loop can skip a frame (the initial start of the coroutine)

yield return null;
while
    ...
    yield
...```

[orchid bane]

Does new WaitForEndOfFrame really happen before LateUpdate?

[dusk apex]

It happens at the end of frame

There's a wait for late update as well but that isn't the issue

The issue is that the coroutine occurs immediately up to the yield statement

[orchid bane]

It shouldn't

It should stop until LateUpdate

Idk how to fix it, for now moved it to LateUpdate and it works

[dusk apex]

When you start the coroutine it'll run up to the end of frame yield

[orchid bane]

Apparently WaitForEndOfFrame isn't waiting until LateUpdate

[dusk apex]

The end of this frame, do this

[leaden ice]

it waits for a very specific point in the frame, much after LateUpdate

it's usually not what you want

usually you just want yield return null;

[dusk apex]

@orchid bane

Just skip the first frame, everything else should be fine

[orchid bane]

Oh I understand

Or not

[dusk apex]

private IEnumerator StopFiringCoroutine() {
        yield return null;
        while (fireRequested)
        {
            print("falsing");
            fireRequested = false;
            yield return new WaitForEndOfFrame();
        }

        print("stopping");
        firing = false;
        StopFiring();
    }```

[orchid bane]

I understand, it sets firing to false and then runs again on the same frame

Thanks a lot guys! 👍🏻

SetActive(true) not working as intended

[uneven slate]

Hello. anyone know how to get the "add key" to show up on just general float values. in this case I can't just change it by some tiny amount to get it to pick it up as a keyframe. example of what I need (works on transform:)

vs what I see on a general script float:

[heady iris]

So it can be keyframed; it just doesn't give you the "Add Key" option?

[uneven slate]

Nope!

or, well, yeah. it can be keyframed, just no add key option.

do I need to put an attribute on the variable or script or something?

[heady iris]

hmm, I see that show up for float fields on one of my classes

specifically, on a float that's part of a struct field

how did you define "Main Rotor RPM"?

[uneven slate]

just a stock standard [serializefield]

    [SerializeField]
    public float MainRotorRPM = 395f;

[heady iris]

are you sure you're actually recording an animation?

I see this when I'm not previewing an animation, specifically

vs. when I am previewing an animation

[uneven slate]

I'm recording in the timeline window, hence why i can record the transform's values

[heady iris]

ah, maybe timeline behaves differently

[wispy cave]

how do i post a forum in unity forums

[heady iris]

doesn't it need an animator on whatever object you want to control things on?

i've barely used timeline

[uneven slate]

it does, adds it automatically when you put it in the timeline

[crude creek]

Hello! I'm currently making a car game and I have a problem. I want to police cars spawn around the player, but I only want them to spawn in top of roads. Any ideas on how to do it? Thanks!

[heady iris]

how are your roads built?

are they a grid of models that snap together?

[crude creek]

yes

[heady iris]

if so, I'd just pick a random road and check if it's near the player

bonus points for randomizing the position on the road segment, but that's less trivial

since different road shapes will have different rules

that's where you might just slap down a few empties as valid car spawn points

[spring creek]

Please don't cross-post. And you were answered, in case anyone else thinks you still need an answer

Edit: sorry for breaking up your suggestion fen 😂

[heady iris]

so, each road piece would have a few GameObjects. pick a random object and put the car there.

[crude creek]

Thank you so much! I'll try that

[heady iris]

Automating the problem is nice, but sometimes it's better to just hand-author a few spawn points and call it a day :p

If you have some kind of navigation system for the cars, you could probably take advantage of that

pick a random point and snap it into a legal position

[crude creek]

thats a great idea too

thanks!

[naive swallow]

...what

[whole portal]

Can I get a bit of help with fixing these errors please ?

My chunk script uses Compute Shaders to update terrain chunks, but I'm running into errors that are a bit puzzling. It handles the creation and updating of terrain chunks. It uses Compute Shaders and Compute Buffers for terrain manipulation.

Exception caught: Value cannot be null.
Parameter name: buffer```
```vbnet
NullReferenceException: Object reference not set to an instance of an object.

What I've Tried:

• Checked whether _trianglesBuffer is null before setting it.
• Logged various variables to debug the state of the buffers and kernels.

I'd appreciate any guidance on how to resolve these errors. I'm leaving the link to my code in case it's needed here: https://pastecode.io/s/ng59uh9v

[knotty sun]

your code post is empty

[whole portal]

I apologise, I forgot to save. It is saved now, please refresh.

[knotty sun]

nope, still empty

[spring creek]

I see a single "S" but that probably isn't what you wanted to share?

[naive swallow]

Hm, yes, I see, I understand everything now

[whole portal]

https://pastecode.io/s/ng59uh9v Please try this, I don't know why it isn't working on hatebin.

[naive swallow]

Hatebin does that sometimes

I don't really know why

[naive swallow]

Seems like _trianglesBuffer is null. It looks like the null check above prints something, but it doesn't actually stop it from trying to use the buffer anyway. Is the log right above this error your "_trianglesBuffer is null before setting the buffer" log?

[knotty sun]

I think it is the Debug.Log at line 184 throwing the NRE
But have a try catch around this line 173
MarchingShader.SetBuffer(kernel, "_Triangles", _trianglesBuffer);
but not around the same line at 186

the structure of the code makes very little sense

[whole portal]

Here's a bit more details in regards with the results form the logs, I'd post screenshots but the logs are too long. Uhm, if you guys want me to add additional debug lines let me know please. I'm trying to fix this since yesterday and can't wrap my head around it.

[knotty sun]

I have a feeling that _trianglesBuffer is not null but it is empty and that is causing
Debug.Log($"_trianglesBuffer count: {_trianglesBuffer.count}, size: {_trianglesBuffer.stride}");
to throw the NRE

[whole portal]

The code worked well before I realised I had to check for neighbouring chunks otherwise when digging between chunks this would happen. So I've tried to implement a dictionary and that functionality. I also have an issue where when I leave a chunk, if I dig on it, the digging information gets lost after I leave that chunk and come back. So these are the issues I am facing.

[knotty sun]

I really think you are going to need the debugger to crack this one

[whole portal]

Well somehow, after adding a few more debug logs in the construct mesh method I only get one error now. I'm once again showing the log in video as I do log a bit more on the buffer now and it's a bit more information, but I'll leave the error down bellow. The rest of the logs are showcased in the video.

The error:

UnityEngine.Bindings.ThrowHelper.ThrowNullReferenceException (System.Object obj) (at /Users/bokken/build/output/unity/unity/Runtime/Export/Scripting/BindingsHelpers.cs:48)
UnityEngine.ComputeBuffer.get_count () (at <915aecf868db4138bef6c93c90c19aea>:0)
Chunk.ConstructMesh () (at Assets/Scripts/Chunk.cs:171)
Chunk.UpdateMesh () (at Assets/Scripts/Chunk.cs:94)
Chunk.Create () (at Assets/Scripts/Chunk.cs:87)
Chunk.Start () (at Assets/Scripts/Chunk.cs:37)```

[knotty sun]

As I said, it is the Debug.Log throwing the error. It is failing to get the count which you are trying to display

it tells you right here UnityEngine.ComputeBuffer.get_count ()

I was wondering if you were trying to pass in the wrong type of data

[whole portal]

Hmm. This is what VsCode shows.

I've added a breakpoint here and attached to unity.

[knotty sun]

you need to put the breakpoint on a debug inside the catch then look

[whole portal]

I think I've made a bit of progress in identifying the erorr wit ha small update on Release Buffers.

[whole portal]

Yup, will do that in a moment.

[knotty sun]

It's obvious the trianglebuffer is null which is what is causing all the errors so you need to see why is it null?

[whole portal]

I think so too, working on it. And by the way thank you very much for taking your time to help, really appreciated.

[knotty sun]

what you need to do is look at the stacktrace when trianglebuffer is null, then work backwards through the code to find out why

so breakpoint on the debug for == null

[zinc parrot]

hey if I have a cloth component on a skinned mesh, why is the bounds in the inspector correct, but the actual bounds displayed in gizmos are static/never change? how do I get the bounds displayed in the inspector in script? because skinnedmesh.bounds dont move with the cloth

interestingly if I turn OFF updatewhenoffscreen suddenly its all the correct bounds

but I cant do that, I NEED it to update when offscreen

heres what happens with it, with the wirebox being the current bounds as reported by SkinnedMeshRenderer.bounds(and also the bounds that unity normally draws over objects, meaning they both report the same)

oh unity 2021 btw

[dawn nebula]

Is there a c# collection that's like a list in that there's an expected order, but you can't have multiples of the same object?

Hashset has the second but obviously not the first.

[whole portal]

Debugging results. It looks like you were right, that one is null. I'm showing the process in the video as well, not sure where to go from here though.

[whole portal]

On it. Thank you for helping with the direction.

First time doing a stack trace here 😄

[modern creek]

I'm wanting to make a Cinemachine setup with a VCam for every unit in the game and a VCam that is the "player override" camera (so a player can just drag-to-pan around the map if they're not following a specific unit).

I'm getting some wonky behaviour though if I just do vcam.position += (Vector3)offset where offset is the amount of "drag" that happened this frame. Do I need to configure a vcam somehow to just make it behave like a normal camera?

oooh wait I'm ... not converting world position from canvas position, nevermind.

[modern creek]

When using cinemachine, my vcam is reporting 0,0,0 for this on mouse down:

RectTransformUtility.ScreenPointToWorldPointInRectangle(Canvas.transform as RectTransform, eventData.position, Camera.main, out Vector3 position);

My understanding is Camera.main will still be correct when the vcam is active?

do i need to add vcams to.. something?

(debug on that line of code)

[heady iris]

what do you mean "reporting 0,0,0"?

[modern creek]

canvas looks right, camera.main is the main camera, click event position looks right.. and yet it's returning 0,0,0

[heady iris]

as in, this is producing a zero-vector?

[modern creek]

the RectTransformUtility.ScreenPointToWorldPointInRectangle() puts 0,0,0 into the out position, yeah

[heady iris]

are you trying to get point on a screen space - overlay canvas?

https://docs.unity3d.com/ScriptReference/RectTransformUtility.ScreenPointToWorldPointInRectangle.html

[rain minnow]

you can checkout SortedSet<T>, a List<T> with a duplicate check, or a custom Collection<T> class . . .

[heady iris]

The cam parameter should be the camera associated with the screen point. For a RectTransform in a Canvas set to Screen Space - Overlay mode, the cam parameter should be null.

[modern creek]

ah, that might be it.. hang on

[heady iris]

i'm unclear what it would even give you if you did that, since screen-space coordinates on an overlay canvas are just the world coordinates, iirc

(notice how an overlay canvas is HUGE in the scene view)

[modern creek]

Ah.. I didn't realize that

So I don't need to convert from screen-world for this?

[heady iris]

what are you trying to do?

[modern creek]

drag the camera around to pan (using cinemachine)

Lemme try without converting from screen to world

[heady iris]

so you've got a top-down camera and you want to be able to grab and drag the ground?

(to move the camera)

[modern creek]

yeah

I did it without the world-to-screen coordinates and it "works" but isn't scaling properly - ie, moving one pixel on screen sends the camera 100 pixels away

I thought I needed to convert the screen coordinate of the event click to world space

[heady iris]

i did that in an RTS by just looking at the screen-space delta, rotating it, and then applying that the position of the camera

i just eyeballed the movement rate

I originally raycasted to the ground, then made sure the camera moved so that the mouse stayed over that exact piece of ground

but it got very wonky at sharp angles

                    Vector2 delta = pointer - draggingLastPos;
                    delta *= 0.4f;
                    delta *= 0.5f + 0.5f * Mathf.InverseLerp(distanceMin, distanceMax, distance);


                    x -= delta.x * Mathf.Cos(pivotRad) - delta.y * Mathf.Sin(pivotRad);
                    z -= delta.x * Mathf.Sin(pivotRad) + delta.y * Mathf.Cos(pivotRad);

man that's some weird code

this was before I knew how to rotate a vector, lol

i think that'd just be Quaterion.AngleAxis(pivotRad * Mathf.Rad2Deg, Vector3.up) * delta

but you get the idea -- measure the screen space delta, rotate it to match the view direction, and move the camera

[modern creek]

this doesn't work either

[heady iris]

line 3 is there so that it goes faster when the camera is zoomed out

[modern creek]

(commented out line was my first attempt - getting the position in world space by converting from the utility method)

[heady iris]

well, you definitely can't just add the position directly

the screen position is X and Y

[modern creek]

it's adding the difference between the last frame..?

[heady iris]

isn't that gonna send your camera flying into space?

[modern creek]

it should match up to pixels moved, shouldn't it?

ie if I move the mouse 5 pixels to the left, setting the camera position 5 pixels to the left?

(in world space coords)

[heady iris]

if you move the mouse up, the Y will change

so you'll be raising the camera

[modern creek]

i'm in "Z" = towards/away

[heady iris]

ah, okay

[modern creek]

gotta grab kids i'll bbl in case you have any ideas 🙂

[dawn nebula]

Can Unity handle an online RTS with ~100 units?

[night harness]

sure

it can handle anything given the right context and standards

[spring creek]

100 is nothing. Yes.
Ecs if you need like a few thousand

[dawn nebula]

Right but I guess the better question is like

Does it have available tooling

To make the process

Not ass

Or will I need to go it on my own?

[spring creek]

What does "not ass" mean?
And tooling for which part specifically?
Probably no though, for the tooling

Gonna need your own pathfinding

Gonna need to make your own unit varieties of course

The NavMesh is much better now in unity though!

[dawn nebula]

Specifically the communication between host and client

For pathfinding I got A*

[spring creek]

Ahhhh, NGO is unity's networking solution.
There's also fishnet, which people really like

I dunno about that side though, sorry

[dawn nebula]

Wasn’t there some new solution?

[spring creek]

NGO

[dawn nebula]

Something released within the last 2 years?

[spring creek]

Is the new one

[dawn nebula]

What’s it stand for?

[spring creek]

Netcode for GameObjects

[dawn nebula]

Ah yes that sounds familiar

[spring creek]

They also have Netcode for Entities for ECS

[dawn nebula]

Got any experience with it? Solid or nah?

[spring creek]

I do not have any, sorry

[dawn nebula]

Fair fair. I’ll give it a try.

[spring creek]

People seem to like it haha

[lean sail]

Ngo isnt recommended for like large player sizes, I'm not entirely sure what "large" would mean so maybe ask in ngo discord.

[dawn nebula]

Ya I don't mean like massively multiplayer like an MMO. 2-4 players, but they're each controlling lots of units.

Think Starcraft I guess.

[lean sail]

I guess then it matters more what you are syncing then and how often, should still be possible but I'd keep an eye on the network profiler occasionally

[modern creek]

I can't seem to get RectTransformUtility.ScreenPointToWorldPointInRectangle() working for the life of me. Code for a mouse down event:

public void OnDrag(PointerEventData eventData)
{
  RectTransformUtility.ScreenPointToWorldPointInRectangle(Canvas.transform as RectTransform, eventData.position, eventData.pressEventCamera, out Vector3 updatedPosition);
  Debug.Log($"Position: {updatedPosition}");
}

Gives me the following (when I drag around 0,0 in world space):

[dusk apex]

Does the event data position ever change? Log it.

[modern creek]

It changes as expected.. it's just.. wrong.. 🤷‍♂️

(those values are near the origin in worldspace but they're clearly screen coordinates)

I'm using a vcam with cinemachine fwiw - but there's only one camera, and eventData.pressEventCamera is null (as expected) since i'm using screen overlay mode on the canvas

Unless I'm supposed to be using "Screen Space - Camera" as the render mode..

In which case it works but now I have another problem.. judder when trying to set the position of a cinemachine vcam

[dusk apex]

Looks like a hover event so perhaps try enter event data instead

[modern creek]

ooooooooooo

There's a typo in that blurb but I found the member.. enterEventCamera vs pressEventCamera, which now works for overlay mode canvas.. not sure why i'm getting judder though, but I suppose that's a cinemachine config thing that I can chase down. Thanks!

[broken light]

how do you instantiate gameobjects only to the prefab from editor code? when ever i instantiate on the target it spawns in the scene and not the prefab

[quartz folio]

have you gone through the prefab talk that is pinned to this channel?

[broken light]

let me check it

i dont see any mention of prefabs in the pin?

[cosmic ermine]

Creating a generic struct, and wondering if there is any "where T :" for numbers? As in uints, bytes, stuff that can be used as an index into an array.

[somber nacelle]

not until .net 7

[cosmic ermine]

and unity is still on an ancient .net version I'm guessing?

[somber nacelle]

yeah, unity doesn't even have .net 5 support. when they finally swap to the core clr we'll get the latest version of .net but that's not expected until next year at the earliest and could potentially be an even longer wait

[cosmic ermine]

unfortunate, thanks for the info!

[fast glade]

Do custom editors literally not work in builds at all? I notice that whenever i run a build all the mechanics that rely mainly on custom editors just break. Ive done the #if Unity_engine but i didnt really think that it would completely nullify all the effects of the custom editor

[somber nacelle]

editor code doesn't exist in a build at all
