[knotty sun]

might be more trouble than it's worth

[prime lintel]

Is there a reason why my transform value is different from what I see in the editor? This is the same object holding the component, yet it returns 10,0 in the code instead of 5,2 as seen in the editor

[knotty sun]

the position you see in the inspector is the localPosition

[prime lintel]

What is the object local to? It's parent I assume?

[knotty sun]

indeed

[wanton cedar]

so is this method called pooling? or am i misunderstanding it? - and how would you go about enabling & disabling?

[knotty sun]

no, pooling is something completely different.
disabling is easy, you just disable everything by default in your scene
enabling you do with a OverLapSphere call and enable everything it returns

[wanton cedar]

OverlapSphere is great!! how did i not hear about this until now....

[knotty sun]

You don't read the docs as much as I do or as much as you should?

[graceful latch]

i really cant figure out why this doesnt work ``` private bool CheckAdjacentTiles(Vector3Int tilePos, TileBase _tile)
{
Vector3Int[] directions = new Vector3Int[]
{
new(0, 1, 0), // up
new(0, -1, 0), // down
new(1, 0, 0), // right
new(-1, 0, 0) //left
};

    for (int i = 0; i < directions.Length; ++i)
    {
        TileBase adjacentTile = tilemap.GetTile(tilePos + directions[i]);
        if (adjacentTile != _tile)
        {
            return false;
        }
    }

    return true;
}

}

its suppposed to check if any of the adjacent tiles on a tilemap arent _tile

but it just always returns false

[somber nacelle]

you want to invert your condition and return statements. otherwise if the first one is not _tile it will return false so it won't even check the others

[graceful latch]

thats fine. i just need to know if any arent.

im basically checking if the current tile is an edge of that type

if that makes sense

[somber nacelle]

also consider caching your directions array in a readonly field of the class instead of creating a new instance each time you call this method

[knotty sun]

logically it's unlikely that all tiles are going to be the same

[somber nacelle]

so then it's doing what you want, no? because surely all of the tiles are not that specific tile you passed in

[graceful latch]

wait. now ive confused myself, is tilebase the type of tile or that current tile

[somber nacelle]

the _tile variable is a specific tile, not a type of tile, but a reference to a specific one

[graceful latch]

this is some generated terrain i have, surely all the grass tiles are the same

its using rule tiles, but you can rule tile in a a basetile variable

[somber nacelle]

sure, they may be the same type of tile. but they are not the same tile. much like how you and i are each a person, but we are not the same person

[graceful latch]

but im checking if the tile is that type

[knotty sun]

if you were laying grass turf would each piece be the same pice of turf?

[somber nacelle]

no, you are comparing the tile against another tile. you are not doing anything with their types

[graceful latch]

when i have basetile as a variable in inspector i set that when building my tilemap, im really confused now i dont do much 2d stuff

these are the tiles i set when building the tilemap

and these are tilebase in code

[somber nacelle]

this has nothing to do with being 2d, this is about the concept of objects. you are comparing the tile objects to see if they are the same object, you are not comparing their types to see if they are the same type of tile object

[graceful latch]

so would checking if that tyle is that variable should work no?

because thats literally how i set it

[knotty sun]

no

[somber nacelle]

just like if you have two gameobjects and compare them. They could be named exactly the same and be in the same exact position, rotation, etc. but they are two completely separate gameobjects

[graceful latch]

so how do i do what im trying to do then

i think i get what you are saying

[somber nacelle]

what are you actually trying to accomplish with this

and don't say "see if the tiles are the same", i want to know the actual problem you are trying to solve
https://xyproblem.info

[graceful latch]

this here literally says tilebase is what im saying

Tile is a current tile in the tilemap

[somber nacelle]

just because it is an instance of the same object does not mean it is the same object

i already explained this

[graceful latch]

there is no need to be so arrogant. i dont know how else to explain what im trying to do

[somber nacelle]

you haven't even bothered trying yet

[graceful latch]

im trying to check if a tile is next to a water tile

red would return false, blue true

i dont know if that helps at all

[jagged tulip]

if i were to do
todolist = gameObject.GetComponent<DataToDo>();
and then
todolist.task = "cooking"
would it change the task variable on the DataToDo class. or would it just change the task in my todolist version

[graceful latch]

im surely correct the way i was checking if a tile was ground or not before without edge checking was just that

i was getting the current tile and checking if it was groundtile

[somber nacelle]

components are reference types, they point to the same object

[graceful latch]

and that worked fine

[jagged tulip]

i'm trying to make all of my Data in one big script that i can access so the often-accessed-variable won't scatter in 5 different script

[somber nacelle]

if you are so certain that worked fine, then you need to compare what you did there with what you are doing here

[jagged tulip]

okay. thanks a lot!

[graceful latch]

okay, thanks for absolutly no help, all you have done is say, you're wrong

you haven't actually tried to help me at all

[knotty sun]

you should use this override of GetTile

public T GetTile(Vector3Int position); 

[somber nacelle]

cool then don't listen to me and go read the documentation since you're so sure that you are 100% right and that i'm not

[graceful latch]

dude i was literally checking if tile was == to a certain tilebase and it was working

[somber nacelle]

if that were working, then why isn't it working

[graceful latch]

ii did this

and that would only place trees on ground tiles

[graceful latch]

if i knew i wouldnt be here

[graceful latch]

thats already what im doing im passing through a vector3 int

[knotty sun]

yes but you are not checking Type which is what this override does

[graceful latch]

there is the actual text file up somewhere

oh you mean put the T there

im confused lol

[graceful latch]

how does one use an override ive never done that

or i just dont understand

[knotty sun]

In this case you provide the generic type argument

[graceful latch]

yeah but how, i feel so stupid rn lol

[knotty sun]

GetTile<WaterType>(position)
or whatever your WaterType is. If it returns null it's not water, if it retuns not null it is water

[somber nacelle]

doesn't seem like they even are using a custom tile type and are just using the built in RuleTile so that won't really be much help to them

[knotty sun]

then they cannot do what they want to do

all tiles will look alike to the Type system

[graceful latch]

so unless i use custom tiles its not possible

[knotty sun]

correct

[somber nacelle]

eh, it's still possible. just a lot more convoluted

[thick terrace]

why would you need a custom tile type here?

[knotty sun]

how if there is nothing there to differentiate the original rule tile

@graceful latch you know the easiest solution would be to maintain your own grid with the tile types in it

[thick terrace]

it's been a while since i touched tilesets but aren't tiles assets? so each grass tile is referencing the same asset for example, and instance identity should be enough to compare (so in this case that's why the tree check was working before)

[graceful latch]

yeah it must be different

or else it wouldnt of worked before

if i make this i++ it partly works but only for some sides

[thick terrace]

are you sure the condition you're checking is right? it seems like you should be checking for adjacentTile == _tile not the opposite, if you want to return false when there's any _tile adjacent

[graceful latch]

no im doing the opposite of that

i want false if there isnt any

true if there is

[somber nacelle]

so you want it to return false if none of the tiles being checked are the same as _tile? and true if any are?

[graceful latch]

no, false if any arent, true if all are.

im checking if the current tile is a ledge

[thick terrace]

just in case, you're also still checking for groundTile, not _tile in that last screenshot 😛

[graceful latch]

well it was only being used to check for ground tile at that point anyway, so that doesnt matter right

but i fixed it

[thick terrace]

maybe stick in a debug log when you return false then, with the adjacent coordinate and name of the tile that it found there?

[graceful latch]

its always failing on the first tile

[thick terrace]

what's at that coordinate in your tilemap then?

[graceful latch]

no i mean its always failing on the first check in the for loop for each tile

[somber nacelle]

remember how i told you that if the first tile is not _tile then it won't even check the others?

[graceful latch]

this time i got this, i feel like im just doing something really dumb somewhere

thats fine though?

[leaden ice]

this is a basic NRE

a reference you are accessing on the indicated line is null

check the line number it is telling you

and look at all the references being accessed on that line

[thick terrace]

is this since adding the log? i guess you're logging something from the returned tile, so that means GetTile is returning null?

[rigid island]

or tilemap is null

[thick terrace]

it's probably not that lol

[rigid island]

do you know for sure or just assuming?

[thick terrace]

i mean this person has been trying stuff for ages and that hasn't been the problem so far so unless something randomly broke we can probably assume

[graceful latch]

i just messed something up nvm that

[graceful latch]

this is whats really displaying

[thick terrace]

can you double check again then, what's at that coordinate in your tilemap?

[graceful latch]

get tile is always null.

[graceful latch]

thats just an offset

its not an actual tile

[thick terrace]

okay, what's at the first tile's coordinate plus that offset?

[graceful latch]

its null for every tile

[thick terrace]

and is there a tile there in the tilemap?

[rigid island]

show your current code

which positions are these, are you using WorldToCell ?

[graceful latch]

wait, i might just be stupid

one sec

[wanton cedar]

so i made it now, but since the gameobjects in my scene are inactive, the OverlapSphere() cant find them.. is there a workaround for this issue?

[wheat elbow]

Hi all,

Just wanted to bump the above in case anyone has worked with virtual keyboards + steam!

I started this thread as well in the steam developer discussions, but I'm still struggling to figure out why the keyboard is not popping up.

While I don't have a steam deck / controller handy, two of my beta-testers (one windows pc + xbox one controller and the other a steam deck) mentioned that the while all the other controls / mappings were fine, when they tapped on input fields, no virtual keyboard was popping up.

For context, here are some threads I had:
https://steamcommunity.com/groups/steamworks/discussions/27/4697910365481113732/ (I think you have to log in as a steamworks developer for this one)

https://adventurecreator.org/forum/discussion/15458/virtual-keyboard#latest

Any advice?
Code is in the parent message that I'm replying to + the forum! 🙂

[mellow hazel]

Does anyone know how to detect if the game is running in a GeForceNow environment without any sdk?

[graceful latch]

you cant.

[mellow hazel]

Only with sdk?

[graceful latch]

indeed

[mellow hazel]

Uff thanks

[graceful latch]

yeah im stupid i need to rethink my system, i just realised why it wasnt working, its because the other tiles dont even exist yet, i dont know how i didnt think of that

im sorry for all the troubleshooting i got you guys to do

i need to generate terrain then objects

which should be simple enough

yep that worked

thanks @thick terrace for all the help though'

even if it was a was fruitless lol.

[hybrid relic]

But with Geforce now you can tell them to launch your game with a specific parameter, so thats prolly the easiest way of detecting it

Just react to -gamemode geforcenow

Or something like that

[hybrid relic]

So technically no, but you can use other ways

Also getting your game on geforce now is prolly the bigger problem, they dont even have some massive titles on there, so id be surprised if they will accept some random indie game

[graceful latch]

not having aaa games is probably more the devs then anything

i think steam already has adding it to geforce now

[mellow hazel]

That's a good idea. Thanks.

[wanton cedar]

This is the spike i get in memory, CPU & rendering, when my player moves one chunk to the side (which instantiates 3 chunks & destroys 3 chunks)...

since its a procedural infinite exploring game, i wont need to save old chunks, so i just destroy them

[hybrid relic]

no problem

[placid summit]

what's in a chunk?

[wanton cedar]

8x8 tiles of road, which is procedurally generated based on neighboring chunks, buildings & some physics props spread out randomly.

[placid summit]

so it is procedurally generating 3 chunks - it could be very slow. Spreads things out over many frames to avoid a spike

[wanton cedar]

how would you acheive this?

[placid summit]

well how does it do it now? A big long function? Break it up and record progress per frame in an Update call. Have a monobehaviour in charge of updating the world

[wanton cedar]

its all pretty much one method, calling the next, calling the next... and so forth.. so i need to break these methods out of this chain somehow?

[placid summit]

tbh Unity is not ready for infinite exploring out of the box, it needs some advanced knowledge. Eventually floating point accuracy goes out the window too if you do not have HDRP or something with the world centre do the player

[tulip breach]

I have my steam game id how can I test the game with it?

[placid summit]

that is one method - I read some dev recently that had just spread world updates over a time period

[knotty sun]

maybe read the steam docs or ask them

[tulip breach]

ok

[wanton cedar]

aaaaah okay got it - so i should probably not spawn all groups of gameobjects at the same time, but spread them out, so the chunk is instantiated, and then the physics props are instantiated when the player moves a within a certain distance of that chunk

or is that stupid? hahahaha

[placid summit]

yes if the spike is too big that will make more smaller ones instead!!

[wanton cedar]

a game is nothing but lag spikes spread out over time

[split junco]

I have implemented a state machine pattern for a gameobject called "Server". The server takes on states such as NormalLoadState, HighLoadState and so on. Here's a basic implementation.

public class ServerLoadManager : MonoBehaviour
{
    public float currentLoad { get; private set; } // Current server load percentage
    public float NormalLoadThreshold = 50f;  // Below this is considered Normal load
    public float HighLoadThreshold = 80f;    // Above this is High load
    public float OverloadThreshold = 95f;    // Above this is Overload
    public ServerLoadState currentState;

    // States
    public NormalLoadState normalLoadState = new NormalLoadState();
    public HighLoadState highLoadState = new HighLoadState();
    

void Start()
    {
        SetState(normalLoadState);
    }

public void SetState(ServerLoadState newState)
    {
        if (currentState != null)
        {
            currentState.ExitState(this);
        }

        currentState = newState;

        if (currentState != null)
        {
            currentState.EnterState(this);
        }

    }


void Update()
    {
       Debug.Log($"Current Server State is: {currentState.GetStateName()}"); //Error at this line
    }

public class NormalLoadState : ServerLoadState
{
    public override string GetStateName() => "NormalLoad Server State";
   
    public override void EnterState(ServerLoadManager server)
    {
        Debug.Log(GetStateName()); //this works
    }

    public override void UpdateState(ServerLoadManager server)
    {
        // Monitor the server's load and transition if it increases
        if (server.currentLoad > server.HighLoadThreshold)
        {
            server.SetState(server.highLoadState);
        }
    }

    public override void ExitState(ServerLoadManager server)
    {
        //Debug.Log("Exiting NORMAL load state.");
    }
}

I get an error when I try to Debug.Log($"Current Server State is: {currentState.GetStateName()}"); Please help!

[knotty sun]

care to share the actual error or should we guess it's a NRE

[leaden ice]

I get an error
What error?

[split junco]

Yes. It's NRE

[leaden ice]

then currentState is null

[knotty sun]

so currentState is null

[leaden ice]

if (currentState == null) Debug.Log("Current State is null");
else Debug.Log($"Current Server State is: {currentState.GetStateName()}");```

[split junco]

Let me try that. Thanks!

[leaden ice]

Debug.Log($"Current Server State is: {(currentState == null ? "null" : currentState.GetStateName())}");```
or ^

[split junco]

Yup. It's null for a brief time during the start and that's it. Thanks!

[placid summit]

hmm why on earth does the visual studio unity project explorer not have a search on it?

[knotty sun]

visual studio has a find option

[placid summit]

I meant for a file - you can search in solution explorer, but I get a bit of a mess from multiple assemblies - so it can appear twice or more!

but that may work also

Ctrl+F class name...!

[knotty sun]

if you have a reference to the class you can also right click and go to definition

[placid summit]

yes I know that much - but I often dont have

[steady moat]

CTRL + T also can help with search

If you want search by type

[tulip breach]

How can I get all a player data in a dictionary with just their id? via unity cloud save

[rigid island]

You'd only be able to grab their public data iirc

they need to be signed in to access their private files

[tulip breach]

I have them signed in im just confused on how to grab all their data because everything on the docs shows how to do it with specific data

[rigid island]

you generally get all the keys then you can put them in the query, they actually made a new Class now that works similiar to query parameters if you ever used traditional Object Document based Storage

https://docs.unity3d.com/Packages/com.unity.services.cloudsave@3.1/changelog/CHANGELOG.html

oh its been there for a while , haven't seen it before lol

[tulip breach]

so this freezes my editor

public async Task<GameData> Load() {
  GameData data = new GameData();
  try {
    var dataDict = await CloudSaveService.Instance.Data.Player.LoadAsync(ListKeys().Result);
    data = dataDict.AsDictionary().ToObject<GameData>();
  }
  catch (Exception ex) {
    Debug.LogError("Failed to load save data from cloud: " + ex);
  }
  return data;
}

more specifically

var dataDict = await CloudSaveService.Instance.Data.Player.LoadAsync(ListKeys().Result);

this line

[rigid island]

what is ListKeys()

[tulip breach]

public async Task<HashSet<string>> ListKeys() {
  var hash = new HashSet<string>();
  var keys = await CloudSaveService.Instance.Data.Player.ListAllKeysAsync();
  for (int i = 0; i < keys.Count; i++) {
    hash.Add(keys[i].ToString());
  }
  return hash;
}

I have 2 total keys

[rigid island]

btw any webcall is especially important you try catch

[tulip breach]

ah true

[rigid island]

put some logs see where it starts freezing

[leaden ice]

well yeah sounds like you're doing I/O on the main thread

make sure you run this in a background thread

[tulip breach]

how do I do this...

[tulip breach]

Freezing on the

var dataDict = await CloudSaveService.Instance.Data.Player.LoadAsync(ListKeys().Result);

its not freezing in listkeys

[leaden ice]

yeah because you're awaiting from the main thread here

how are you running Load()?

[rigid island]

I wonder if its too many keys to run at once

[tulip breach]

public void LoadGame() {
  this.gameData = Load().Result;
  if (this.gameData == null) {
    Debug.Log("No data was found. Initializing data to defaults");
    NewGame();
  }
  foreach (IDataPersistence dataPersistenceObj in dataPersistenceObjects) {
    dataPersistenceObj.LoadData(gameData);
  }
}

[leaden ice]

yewah if you do Load().Result you're awaiting it right there

it's async

[rigid island]

ohhh nice catch

[tulip breach]

ah ok

[leaden ice]

basically LoadGame needs to itself be async

or you need to use a coroutine

or just periodically check in Update if the task is done

[chilly surge]

Or .ContinueWith().

[tulip breach]

I've never read up on this, how is it used?

[rigid island]

https://learn.microsoft.com/en-us/dotnet/standard/parallel-programming/chaining-tasks-by-using-continuation-tasks

[tulip breach]

👍

[chilly surge]

I wouldn't really suggest using it, it how async/await works under the hood (you can think of await as compiling rest of the code into .ContinueWith)

In general, I would suggest you to pick one (either coroutines or tasks with async/await) and stick to it throughout your entire project. It gets really ugly if you start mixing the two.

[jaunty sleet]

is anyone familiar with render textures?

[rigid island]

https://dontasktoask.com

[jaunty sleet]

I have one in my game and I am rendering to it from a camera with the background set to solid color with a fully transparent color. I also have the render texture set to a color channel that has an alpha channel. However, the alpha channel on the render texture is fully opaque. I'm not sure why the alpha isn't showing in the render texture

[leaden ice]

which render pipeline

[jaunty sleet]

URP

I am not using any shaders here though, just a single render texture

[leaden ice]

sure but camera settings depend on the RP

which is why I asked

[jaunty sleet]

ah ok

[leaden ice]

https://discussions.unity.com/t/render-texture-transparency-not-working-anymore-in-urp-coming-from-lwrp/759216/16

here's a thread about it

apparently the "render post processing" checkbox breaks this?

[jaunty sleet]

I havent tried turning that off, lets see

oh my god that fixed it

why would that break it? so dumb

thanks 👍

[tulip breach]

Ok im getting a new error now....

public async void LoadGame() {
  this.gameData = await Task<GameData>.Run(Load);
  if (this.gameData == null) {
    Debug.Log("No data was found. Initializing data to defaults");
    NewGame();
  }
  foreach (IDataPersistence dataPersistenceObj in dataPersistenceObjects) {
    dataPersistenceObj.LoadData(gameData);
  }
}

this is how I ended up on running load async

[tulip breach]

but now this is having issues....

[tulip breach]

it freezes if I try to just run await Load()

public override void OnServerAddPlayer(NetworkConnectionToClient conn) {
  UnityEngine.Debug.Log("Adding " + conn + " Player prefab");
  PlayerObjectController GamePlayerInstance = Instantiate(GamePlayerPrefab);
  GamePlayerInstance.ConnectionID = conn.connectionId;
  GamePlayerInstance.PlayerIdNumber = GamePlayers.Count + 1;
  GamePlayerInstance.PlayerSteamID = (ulong)SteamMatchmaking.GetLobbyMemberByIndex((CSteamID)SteamLobby.Instance.CurrentLobbyID, GamePlayers.Count);
  PlayerInstance.Add(GamePlayerInstance);
  NetworkServer.AddPlayerForConnection(conn, GamePlayerInstance.gameObject);
  DataPersistenceManager.Instance.LoadGame();
}

this is where its being called and idk how to make it async honestly

[ivory cove]

Is it possible to convert a distance on the screen to world space distance, depending on the camera? Pretty much I have a map camera and I need to know how much screen distance between objects on the map UI is versus world space and how far they are actually in the scene.

[chilly surge]

Don't do Task.Run, just simply await Load().

Task.Run specifically runs it on a thread pool, and most Unity APIs can only be accessed on main thread.

[cosmic rain]

You can take 2 points(either in screen space or world space) that are visible on the map, convert them into the other space, calculate the distance for both spaces and find the ratio.

[hybrid relic]

Raycasts, there is a raycast that does exactly what you want, i just forgot the name of it, but if you look into raycasts for your needs you should find it

[hybrid relic]

A raycast would do the job with the 2 points for you, i just cant remember the function name of the raycast for screen to world space

[iron sentinel]

There is a direct function which does this I forgot

[leaden ice]

World space distance depends on a few things like how far away from the camera you want. There's Camera.ScreenToWorldPoint, Plane.Raycast, and Physics.Raycast that can all be used depending on the circumstance.

[hybrid relic]

There is also a raycast method using the screentoworldpoint, which im having in mind, which would fulfill what he needs, i just cant find the name of it online for some unholy reason

[ivory cove]

So to give more insight about my situation, pretty much the map technically doesn't have any UI elements besides the necessary ones to display what my map camera is seeing, so it's pretty hard to actually get two points on the map. For your raycast thing, would the raycast come from the map camera and land accordingly to where the mouse is? If so, that is correct that is literally exactly what I would need

[hybrid relic]

Oh its just using the mouse pos as a ray data and then using a normal raycast, so you could do that without a mouse, bit just the position of the minimap

Oop brainfart, i thought it was a raycast function

[hybrid relic]

100%

Click mouse and it raycasts to the actual point in worldspace

Ray r = Camera.main.ScreenPointToRay( Input.mousePosition);
if (Physics.Raycast(r, out hit))
{
     Transform objectHit = hit.transform;
}

Phone coding so if its bad formatted shame on me

But you get the Idea

I really thought this was a raycast function and not a camera function lol

Also this is like really old code so it might work a bit differently in Unity 22 or 6

[ivory cove]

I see I see, the only thing is, I wouldn't want the ray to go to exactly where the mouse if if that makes sense. This is a picture of my map. It's a little hard to see but the little icons at the very top are the teleporters, which are way off the screen, as the map camera is much larger than the player's camera. If I were to click on that icon would the ray be at that teleporter or would it be hitting the floor under the map if that makes sense.

[hybrid relic]

Hmm is that map an image or like a zoomed out camera

Instead of focussing the main camera, maybe use that zoomed out camera, but idk how well that works with the mouse position

Trail and error tbh

[ivory cove]

Ya what you are saying works with the zoomed out camera that would be so nice xD I'll give it a shot

[hybrid relic]

Unless someone else here that did this before has a better solution

I guess

I never did anything like this

[ivory cove]

Ya I was originally going to use math to convert screen distance to world distance but it was going to be a huge headache was just wondering if anyone had a easier solution

[hybrid relic]

Try it out, if it doesnt work maybe playing around with the code in how you create the ray is a good idea

[ivory cove]

Yep yep! I'll give it a shot pray for me it works LOL

[hybrid relic]

Maybe it works, defo easier then this lol

Anyways its 1am im gonna bounce, wish you luck

[ivory cove]

ty for the help xD gn

        currentInput = new Vector2((IsSprinting ? sprintSpeed : walkSpeed) * Input.GetAxis("Vertical"), (IsSprinting ? sprintSpeed : walkSpeed) * Input.GetAxis("Horizontal"));

        float moveDirectionY = moveDirection.y;
        moveDirection = (transform.TransformDirection(Vector3.forward) * currentInput.x) + (transform.TransformDirection(Vector3.right) * currentInput.y);
        moveDirection = moveDirection.normalized * Mathf.Clamp(moveDirection.magnitude, 0, walkSpeed);
        moveDirection.y = moveDirectionY;
    }

I tried adding - sprintSpeed after the 0 in that clamp but that did not work

[leaden ice]

they're saying use sprintSpeed instead of walkSpeed while sprinting

[lean sail]

its hard to understand because this is an awful way of writing code. split some of those statements up and itll be at least easier to see the intermediate steps.
that 0 - sprintSpeed thing looks like "0 to sprint speed" rahter than 0 minus sprintSpeed

[dusk apex]

The response or the initial comment post? Maybe just ask the question of concern in regards to your/the code?

[leaden ice]

but yeah this is pretty convoluted

and you're involving the sprinting/walking speeds in multiple places

theyh should just come in at one place

honestly I wouldn't normalize the input

just clamp it

then multiply by the speed at the end

[slow delta]

I have to normalize the input to prevent the speed from doubling when holding W and strafe

[leaden ice]

no

you don't

clamping it is the superior way to do that

[slow delta]

changing it from walkSpeed to sprintSpeed worked, thank you. I may refactor the code later but I'd rather build something that works now and worry about that later.

[lean sail]

this line
moveDirection = moveDirection.normalized * Mathf.Clamp(moveDirection.magnitude, 0, walkSpeed);
can be replaced with this method also
https://docs.unity3d.com/ScriptReference/Vector3.ClampMagnitude.html

whatever tutorial you're following is definitely questionable

[slow delta]

its this one
https://www.youtube.com/playlist?list=PLfhbBaEcybmgidDH3RX_qzFM0mIxWJa21

im guessing some things may have changed in 3 years lol

[leaden ice]

private void HandleMovementInput(){
    Vector2 input = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
    input = Vector2.ClampMagnitude(input, 1);

    float moveDirectionY = moveDirection.y;

    moveDirection = transform.forward * input.y + transform.right * input.x;
    // add speed
    moveDirection *= (IsSprinting ? sprintSpeed : walkSpeed);

    // add y back
    moveDirection.y = moveDirectiony;
}```

I would do it this way

much simpler, more readable

[slow delta]

so why dont we want to use normalize here?

[leaden ice]

and clamping lets you move at speeds between full joystick actuation and 0

because normalize doesn't let us use a joystick properly

i.e. if we tilt our joystick halfway we move half speed

that doens't work with normalize

[slow delta]

so it's basically future proofing for controllers?

[lean sail]

actually now that i look at it closer, the logic seems very flawed. they copy the y value, seemingly so not to overwrite it with the following lines, but the normalize still uses the Y value meaning if the player has vertical motion they'll be moving slower horizontally.

[leaden ice]

yeah

[slow delta]

I really appreciate that

[slow delta]

switched to this for readability and the better method and it's smooth as butter now. Thank you

probly gonna switch to a better tutorial like Brackeys at this point, was mainly on this one to get some specific features

[lean sail]

brackeys has lots of flaws in his tutorials, probably worse than what youve linked. honestly most of the tutorials will have issues if it doesnt fit your exact game

[slow delta]

I have a background in software development so I'm mostly using the tutorials to understand the engine calls

granted I've never played with movement, quaternions, or quads before

[soft shard]

I think the docs do a pretty good job of explaining the engine calls, and most pages show examples of how to use them, albeit quaternions in general can be difficult to understand

[inner shuttle]

is it possible to access the transform of the NavMeshAgent collision cylinder?

[leaden ice]

The Transform component can be accessed from any component or GameObject with .transform

But somehow based on your question I don't think the Transform is actually what you're asking about

[inner shuttle]

yeah its weird im not completely sure what it is i looked about on docs and saw collision cylinder was mentioned, and thats what is moving with my character as it uses root motion and consequently updatePosition is disabled

i just want to be able to offset it a bit to prevent my character from flicking back to it occasionally

[leaden ice]

You can access the height and radius of the agent:
https://docs.unity3d.com/ScriptReference/AI.NavMeshAgent-height.html
https://docs.unity3d.com/ScriptReference/AI.NavMeshAgent-radius.html

[inner shuttle]

thats not what i need, i need the actual world transform

[leaden ice]

and vertical offset here: https://docs.unity3d.com/ScriptReference/AI.NavMeshAgent-baseOffset.html

The Transform is... a separate component

[inner shuttle]

okay

[leaden ice]

mentioned here

[inner shuttle]

as i said though updatePosition is disabled will that affect it>

[leaden ice]

I don't think it's relevant to the question

but like

can't you just solve this in the inspector

[inner shuttle]

okay

[leaden ice]

by changing the vertical offset?

idk, I'm a bit confused about what you're actually doing or trying to do here

it seems weird to use a root motion animation with a NMA

sounds like you have two or more competing things controlling the position of the object then

[inner shuttle]

this is literally my only problem that ive had with this agent

and is what im trying to fix

[leaden ice]

yeah this is happening because your animation is controlling the position of the object separately

you probably want to change that

[inner shuttle]

ok

or i could just set a higher stopping distance for the agent

[young tapir]

Has anyone got any decent PID "intros"? I'm looking to create an interactive UI (VR game) but can't quite rap my head around the smooth movement. I've been digging around google for a bit now and can't find anything that explains how exactly they work

[hushed cloud]

Is it possible to move a text mesh pro (TMP) world-space object without causing massive lag?

[latent latch]

Why would it cause massive lag

[maiden fractal]

I cannot think of single reason it would cause lag let alone massive. I thought the transforms are just matrix transformations

[hushed cloud]

Seems to be related to the use of SmoothDamp. MoveTowards doesn't cause lag

LateUpdate makes it lag less for whatever reason 🙃

Or maybe not

[latent latch]

Oh, you're talking about the interpolation of it

This happens only with TMP? How about just general mesh renderings

[maiden fractal]

Really hard to help without seeing the code and knowing bit more about the use (how many of the objects with the code etc.)

SmoothDamp seems to only do some basic arithmetics so it shouldn't really cause a lot of problems unless you are doing thousands of those every frame

[mint harbor]

I am rying to align 2 hex objects upon collision based on collided edge.
On the image you see 2 edges that are marked in red - that is the result of collision. The goal is to transform (position and rotation) "grey" hex in such a way so that 2 red edges are aligned (as shown on the 2nd image).
Known vars are: edge points, their midpoints, hex positions and rotation.
Maybe someone can point to the right direction?

[fallow quartz]

in VSCode when i press ctrl + shift + space and i cant see the overload of the methods, i tried a lot of possible solutions from google and none of them works

On my PC at home it works but not on the laptop

[mellow sigil]

Position is easy, it's blue hex position + 2 * (blue edge midpoint - blue hex position)

[knotty sun]

the rotation should be as simple as set grey rotation = blue rotation

[mellow sigil]

Rotation can be calculated by taking vectors (grey edge midpoint - grey hex position) and (blue hex position - blue edge midpoint), the angle between them is the amount the grey hex needs to rotate

If it doesn't matter which edges touch then yeah just set the rotation to match the blue one's

[mint harbor]

edge matters.

@mellow sigil , thank you, will try

[knotty sun]

you can still use gray rotation = blue rotation and then rotate (360/6) * edge number

[mint harbor]

That us basically placing the hex into other hex and then applying an offset based on midpoint direction with magnitude of 2. Almost works, the magnitude for sure has to be adapted; maybe per edge.

Unfortunately, the angle looks off.
@mellow sigil , with the angle did you mean?

var dir1 = (Vector2)transform.position - greyEdgeMidpoint;
var dir2 = blueEdgeMidpoint - (Vector2)other.gameObject.transform.position;
var angle = Vector2.Angle(dir1, dir2);
Debug.Log("angle " + angle);
transform.Rotate(0, 0, angle);

That is similar to:

var angle = Mathf.Atan2(dir1.y, dir1.x) * Mathf.Rad2Deg;
var angle2 = Mathf.Atan2(dir2.y, dir2.x) * Mathf.Rad2Deg;
var rotationDifference = angle2 - angle;
Debug.Log("rotationDifference " + rotationDifference);

But both overshoot the angle. The issue was that position or angle must take into account modified edge, midpoints after pos/angle modification. All works after that 🙂 thank you

public async void Start() {
  try {
    await UnityServices.InitializeAsync();
    SetupEvents();
    SignInWithSteam();
    this.dataPersistenceObjects = FindAllDataPersistenceObjects();
    await LoadGame();
  }
  catch (Exception ex) {
    Debug.LogException(ex);
  }
}

How can I make sure that sign in with steam is called before await LoadGame()

sorry correction

how can I make sure sign in with steam is done before loadgame is called

[thick terrace]

that's kind of impossible to answer without seeing what SignInWithSteam does, but you're probably going to have to await it

[tulip breach]

private void SignInWithSteam() {
  m_AuthTicketForWebApiResponseCallback = Callback<GetTicketForWebApiResponse_t>.Create(OnAuthCallback);
  SteamUser.GetAuthTicketForWebApi(identity);
}

void OnAuthCallback(GetTicketForWebApiResponse_t callback) {
  m_SessionTicket = BitConverter.ToString(callback.m_rgubTicket).Replace("-", string.Empty);
  m_AuthTicketForWebApiResponseCallback.Dispose();
  m_AuthTicketForWebApiResponseCallback = null;
  Debug.Log("Steam Login success. Session Ticket: " + m_SessionTicket);
  // Call Unity Authentication SDK to sign in or link with Steam, displayed in the following examples, using the same identity string and the m_SessionTicket.
  SignInWithSteamAsync(m_SessionTicket, identity);
}

[thick terrace]

you could adapt this so the OnAuthCallback sets the result on an AwaitableCompletionSource if you want to make it properly awaitable, otherwise maybe just have SignInWithSteamAsync set a flag when it's done then wait for that in a loop in Start like while (!m_steamSignedIn) { await Awaitable.NextFrameAsync(); }

something like this should work:

private Awaitable SignInWithSteam() {
  var completion = new AwaitableCompletionSource();

  m_AuthTicketForWebApiResponseCallback = Callback<GetTicketForWebApiResponse_t>.Create(async callback => {
    m_SessionTicket = BitConverter.ToString(callback.m_rgubTicket).Replace("-", string.Empty);
    m_AuthTicketForWebApiResponseCallback.Dispose();
    m_AuthTicketForWebApiResponseCallback = null;
    Debug.Log("Steam Login success. Session Ticket: " + m_SessionTicket);
    // Call Unity Authentication SDK to sign in or link with Steam, displayed in the following examples, using the same identity string and the m_SessionTicket.
    await SignInWithSteamAsync(m_SessionTicket, identity);

    completion.SetResult();
  });
  SteamUser.GetAuthTicketForWebApi(identity);

  return completion.Awaitable;
}

[tulip breach]

im on unity ver 2022.3 and dont have Awaitable....

[thick terrace]

you can do the same thing with Task and TaskCompletionSource then, although it doesn't have a SetResult with zero parameters like Awaitable so you'd have to do SetResult(null)

[tulip breach]

Sorry for being kindof dumb rn but after this

private Task<bool> SignInWithSteam() {
  var finished = false;

  m_AuthTicketForWebApiResponseCallback = Callback<GetTicketForWebApiResponse_t>.Create(async callback => {
    m_SessionTicket = BitConverter.ToString(callback.m_rgubTicket).Replace("-", string.Empty);
    m_AuthTicketForWebApiResponseCallback.Dispose();
    m_AuthTicketForWebApiResponseCallback = null;
    Debug.Log("Steam Login success. Session Ticket: " + m_SessionTicket);
    // Call Unity Authentication SDK to sign in or link with Steam, displayed in the following examples, using the same identity string and the m_SessionTicket.
    await SignInWithSteamAsync(m_SessionTicket, identity);
    finished = true;
  });
  SteamUser.GetAuthTicketForWebApi(identity);

  return Task.FromResult(finished);
}

How should I trigger the LoadGame(); function

[thick terrace]

you're immediately returning false here, you need a completion source so the result can be set by the callback

but if you fix that, you can change the line in your Start method to await SignInWithSteam()

[mellow sigil]

Nice, but the distance between the midpoint of the hex and a midpoint of an edge is the same for every edge

[mint harbor]

yes. But I had to use atan approach as it accounts for negative angle in certain cases. Thank you for the assistence.

[nova leaf]

Idk if this makes sense but, Is there any way to not force code implementation of variables/fields when I apply an interface to my monobehavior script, and just show them in the inspector to change, and only force functions?

[warm cosmos]

how does unity detect what a raycast hits? is everything in the scene in a hidden quadtree or spatial hash grid

[naive swallow]

Colliders. In 3D, it uses PhysX, in 2D it uses Box2D. You'd need to look up how those physics engines handle colliders to know for sure

[knotty sun]

inside your computer is a little demon who models your scene in plasticine then runs around very quickly with a ball of string and a tape measure

[latent latch]

interfaces force the implementation, that's the idea. But, you don't need to add logic to them if you don't want to.

[thick terrace]

if you want default implementations of fields you'd have to use a base class instead of an interface

[warm cosmos]

feels that way sometimes

[storm ivy]

Hi everyone! I’m a beginner working with prefabs, and I’m running into some issues with maintaining references in my Unity project. I have a car prefab that I spawn at runtime, and it needs to be assigned to the camera, but the reference to the car is lost every time I spawn it. Right now, I’m using FindObjectWithTag in Update() to re-assign it to the camera, but I know this might not be the best approach. The car also has ui button references for touchscreen movement (forward and backward), and because it’s a prefab, these references in the inspector are empty. I know I could assign them with a script, but it seems like it could get overly complex. Is there a recommended way to handle these references efficiently without a large script? Thanks!

[rigid island]

don't crosspost

[next rain]

Anyone who knows how I can join with my friend in unity please dm me.

[latent latch]

Sorry, kinda read over this a little fast, but I think the answer to this is to serialize the backing field if I'm reading it right via:

[field: SerializeField] public int MyInt { get; set; }```

One thing to note is that interfaces don't implement fields, but properties

[sleek bough]

Using version control. Git is a popular solution, or Unity built-in one. !vc

[tawny elk]

Using version control in Unity

Unity Version Control

• Getting started

Git

Get the latest .gitignore file from here. It should be placed at the root of your Unity project directory.

Git has a lot of popular client apps to manage it.

Sry dude

I wanted to get the answer

[next rain]

Can you come into a vc?

[sleek bough]

No, there's a wealth of materials online on the topic. Only have to look.

Also linked you a tutorial as well

[rigid island]

I'm using Unity pooling just fine with other scripts/objects... but for some reason here the projectile gets released then collides again while disabled I guess? looking at the logs... causing this already released pool error.
Been at this since last night, Its probably something obvious I'm missing , hoping someone can clear something to look that haven't.. I have no idea where to even look anymore, my collision seems to be triggering more than once I think? at least it was doing so during OnTrigger, switched it to OnCollision but still happens just less frequent. The setup seems the same as my other projectile that works fine. how can it be triggering a Collision message when it was disabled (according to log message above it)

ops.. here is my enemy projectile script https://hatebin.com/orzvrhqbqi

[latent latch]

You can also whip up your own pooling in no time if you wanted to just go that way

[sleek bough]

It just might hide the problem

[rigid island]

I could but it works fine in other scripts, and yeah I agree with Fog thats just masking something weird going on

why would a disabled object trigger another collision message

[sleek bough]

One of those bugs you would spend hours writing debugging tools for to figure out what exactly is happening.

[latent latch]

Is disabling end of frame? Could be something related

[rigid island]

I'm so confused why this isn't happening in my other projectile for player

more or less the same script

https://hatebin.com/epiiouurfg (Player Arrow)

[latent latch]

I've had problems before with OnTrigger method where I've set my own flagging so prevent other acting upon it

[rigid island]

isn't that what I did? or am i confused by what you said?

private void OnCollisionEnter2D(Collision2D collision)
    {
        if (hasHit) return;
        rb.simulated = false;
        hasHit = true;```

also it was worse on trigger but oncollision i switched it and still does it freakness

doc just says

Collision events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.

idk if that includes Disabled GameObjects ? if so why is other projectile (arrow) not doing it

[sleek bough]

So the primary problem is that event getting triggered twice

[rigid island]

yea..gotta love these logs..
go_-37050 trying to release go_-37050 go_-37050 Disabled go_-37050 collision with WallTile(Clone) go_-37050 trying to release go_-37050 InvalidOperationException: Trying to release an object that has already been released to the pool.

could it be because I'm teleporting it while disabled?

so weird, why would it hit something..should i move the rb.position ?

[sleek bough]

What makes the setup different from the other object, that does work properly

[latent latch]

Well, the flagging seems fine, so it points to how ReleaseToPool is being called

assuming that's the only place the flag is being reset

[rigid island]

indeed

[rigid island]

i sent both scripts afaik I know nothing, maybe the shooting?

In the Both they use a coroutine to shoot, so its very similar.

[latent latch]

So for ReleaseToPool is queuing back into the pool?

[sleek bough]

You seem to have additional condition filtering on collision, maybe that protects it

[latent latch]

why don't you just reset the flag on dequeue

[rigid island]

this gives me an idea

[latent latch]

because how the code reads is you're unsetting the flag 5-6 lines after setting it

so it's still in the same frame

[rigid island]

I think i see the issue

the Reset in my arrow ( the one that works) is done on the Get / requesting from pool

In my enemy one it resets on release and probably causing as you said weird order of frame issue

I will reset it on Get only and see if its gone

Yay! seeems to fixed it 999+ debugs and no errors
thanks help me see this in diff prospective
@sleek bough @thick patio

[dusky pelican]

If we load the scene async, all the awakes and starts are calling? I mean i need to wait for all the awakes and starts before loading data. Is it works this way?

    {
        await SceneManager.LoadSceneAsync(sceneName, LoadSceneMode.Single);
    }

    public static async UniTask LoadDatas()
    {
        await LoadLevelAsync(newSceneName);
        GameManager.Instance.PlayerData.Load();
    }```

[thick terrace]

yes, they should both be called i think? Awake gets called immediately when the scene loads and Start is called earlier than the sync context update in the frame lifecycle so it should have happened by the time you resume from the await in LoadDatas

[south ravine]

how do you access the cinemachine priority to change between cameras. I cant seem to figure it out.

[leaden ice]

1. get a reference to the virtual camera
2. set the priority

[rigid island]

same way you access every other property in a component , use a reference lol

[south ravine]

when I define a variable for the object with the cinemachine component, nothing comes up and it just gives an error

[rigid island]

show code

[leaden ice]

Cinemachine is not a thing

[south ravine]

i dont think i should just write cinemachine

[leaden ice]

it's a namespace

[rigid island]

Cinemachine is not the component

[south ravine]

yea

[leaden ice]

no you shouldn't

CinemachineVirtualCamera

[latent latch]

I think they reduced it to CinemachineCamera now in unity 6

or maybe im thinking of something else

[rigid island]

always look at the names here usually (without the space ofc)

[south ravine]

still error

[leaden ice]

what error

you have to read the actual error

probably you're just missing a using directive

[south ravine]

could not be found

[latent latch]

right click on it

[leaden ice]

that's not the full error

are you missing a using directive or assembly reference

this means things

[south ravine]

nevermind

i think i got it

[leaden ice]

CinemachineVirtualCameraBase also would work:
https://docs.unity3d.com/Packages/com.unity.cinemachine@3.1/api/Unity.Cinemachine.CinemachineVirtualCameraBase.html#Unity_Cinemachine_CinemachineVirtualCameraBase_Priority

[latent latch]

Yeah I think they changed it to CinemachineCamera now in Unity 6

they also changed the namespace to Unity.Cinemachine

[leaden ice]

Nah, both CinemachineCamera and CinemachineVirtualCamera exist

they are separate subclasses of CinemachineVirtualCameraBase

Ah you're right actually

[latent latch]

Ah, I think I may be having a linking problem then with vs code then

[leaden ice]

VCam is obsolete

[latent latch]

oh?

[leaden ice]

deprecated rather

stillCinemachineVirtualCameraBase is a thing

[latent latch]

I loaded up an older project into 6 and all the cinemachine methods just complaining so somethings up

[knotty sun]

yep, breaking changes in 6

[sleek heath]

yeah, you now have a CinemachineBrain as well

very complicated, but more finer control

Anyone familiar with Text Animator by Febucci?

I am trying to get the current text of the string displayed by the typewriter. The only text I can get is the textFull which is the entire text including text that hasnt been shown yet. Any way I can get just whats being shown? Thanks. I checked documentation but couldnt find anything

I am essentially trying to detect whether the TMP_Text isTextOverflowing when each character gets added, but it returns true even if the typewriter only printed the first letter when i check it with the textFull.

if there was like a typewriter.TextAnimator.isTextOverflowing that would be perfect but I can't find something like it

Any help is appreciated, thanks.

[short quiver]

I'm looking for some help with game animation states! I'm working on a fighting game, and the characters have a game-logic FSM, governing what actions they're able to do. (If they're shielding, they can't attack; if they're knocked down, they can't move; etc)
I'm also working on adding animations to the models. I approached it in the way that I'd seen in all of the tutorials, using the Animator Controller. I realized that, in the Animator Controller, I ended up reimplmenting what's already in my character's game-logic state.
Are there patterns I can follow to base the character's animation state on their game-logic state directly?

[nova leaf]

yeah no i meant them only being visible in the inspector without adding in code

[somber nacelle]

no, you have to implement interface members. that's kind of their whole deal

[hybrid relic]

That would make 0 sense

[knotty sun]

how could they be visible in the inspector whilst not being in the code?

[nova leaf]

idk i did that once accidentally xd i wasn't with an interface, but i forgot how i did it

[somber nacelle]

it was likely with inheritance

[knotty sun]

abstract class

[nova leaf]

ah yeah but then i can use max one.. hmmm

[knotty sun]

not really, you can build an inheritance chain although you should do so with caution

[nova leaf]

uurgh i guess i will use interfaces then. it was just an idea to simplify

[knotty sun]

horses for courses, chose with care

[somber nacelle]

what are you actually trying to accomplish? because choosing between an interface and inheriting a class should not be dependent on what is drawn to the inspector

[nova leaf]

just adding pre made modules to a script, without having to implement stuff like strings for names or sprites for icons in code, and just setting them in the inspector, but still having to add the function the module requires

but not important

forget what i said

[tulip spruce]

Apologies for interrupting any previous conversation.

When the player dies a scene should load with a username text promting user to input a name. but should also be able to press play or quit too. this menu should looks the same as the startmenu except the text input thing. Is it better to have two different scences for that or have a deactivated element in the startscene and use same scene for gameover scene but with a logic saying if <player has died in gamescence> activate this gameObject. Which is the best?

[knotty sun]

deactivated object

it would be ridiculous to duplicate a complete scene just to add one extra UI element to it

[nova leaf]

you can add the screen to the players ui too then it has nothing to do with a scene

[tulip spruce]

Ok. Thanks

[tulip spruce]

add the screen?

[nova leaf]

the game over/ respawn buttons

[knotty sun]

he means a canvas, also an option

[tulip spruce]

oh

ah similar to how i made the resume button on escape press

[nova leaf]

because i thought adding for example all this to every single script is annoying, and it would be better to just add the module (interface) and set the values in the inspector

[somber nacelle]

what kinds of objects need all of that? because it sounds like you probably want a shared base class

[nova leaf]

i have a mod system to create custom units and i thought about making it more simple lol

just adding mod

and not all the code

[somber nacelle]

or even just a specific component with all that information

[nova leaf]

yeah but yk i thought instead adding 5 or so components in the inspector just adding the words to the script, which also has better overview for the user but i guess you are right

[knotty sun]

you're doing network stuff without, apparently, knowing the basics of C# structures, not a good plan

[nova leaf]

no it's not

what could go wrong lol

[knotty sun]

exactly, best of luck with that

[nova leaf]

if both players have the same script there is nothing that can go wrong

[nova leaf]

it works perfectly so far

[knotty sun]

if you don't know wtf you're doing, nothing can go right

[nova leaf]

i said it already works so i guess ik what i am doing :P

[knotty sun]

big doubt

[nova leaf]

wtf 💀 if it works it works wdym

anyway we should stop

[knotty sun]

spoken by someone who knows nothing about networking

[nova leaf]

do your parents just dont love you or why are u so angry

[knotty sun]

because I hate to see people wasting their time

[nova leaf]

then stop wasting your time arguing with someone who has a working game, with good performance, even with not the best approach
let people do what they want
also, learning is never wasting time, thats why i ask here. thats what this server is about

[somber nacelle]

don't expect people to bother helping you if you try and do something stupid like make a multiplayer game with no experience

[nova leaf]

? networking for gameobjects is simple and makes stuff like this possible

and i dont have problems

[somber nacelle]

you will

[nova leaf]

are you all just jealous that i have a working game

😭

[somber nacelle]

lmao no. your "working game" is probably barely even a prototype anyway

[nova leaf]

it is not

wtf

;3 jealous

[somber nacelle]

nobody here is jealous or really even cares about you or your game. but don't expect people to help you when you run into issues with networking because you've not bothered learning the basics

[nova leaf]

the networking is finished god damnit and i didnt ask about that

i did NOT EVEN MENTION IT

[latent latch]

No too sure what you mean. They actually won't be visible in the inspector if you don't add the [field: ...] attribute, but you'll not be able to serialize a value onto it from the inspector

or do it the basic way of adding secondary private field yourself and serialize that

[nova leaf]

yeah but thats the point... i want them to be visible ._. just not in code

i gave up on that idea tho, but thx for wanting to help :)

[latent latch]

Ah, yeah. Kinda hard to avoid that but honestly what you have there looks clean enough

the [field: ..] backing really cuts down a lot of code

I have a player that can move pretty fast. Strafing at 100kph or something it's very obvious that shooting seems to come from a position slightly behind where the player is now. (bullets are created as a struct that are handled in a fixedupdate and lerped from last frame position and this frame position. I tried setting posiation as gunTransform.position + shooterRigidbody.velocity * Time.fixedDeltaTime , but that hasn't fixed it. Is it that when a bullet is created it's position and lastposition are set to the same position, which are lerped between in update, before a fixedupdate gives it a real last frame position for the next frame.... how is this normally handled in fast moving fps situations?

[cosmic rain]

How are you moving your character? If you're using physics to move it, it would move at the same rate as your bullet, so both would be at the same position when bullet instantiates.

Let's say I want to play audio on a timer. I have a VERY BASIC movement for my player, it basically sets float x and float y to the Vector2 float values and makes a vector to identify the direction and the charactercontroller moves via that. How can I make it so for example, if I check that the magnitude is greater then 0, footstep audio plays on a fixed timer?

float x = m_Actions.Player.Move.ReadValue<Vector2>().x;
        float y = m_Actions.Player.Move.ReadValue<Vector2>().y;
        Vector3 vector = (transform.right * x + transform.forward * y) * m_MoveSpeed;
        vector.y -= m_Gravity;
        m_CharacterController.Move(vector);

[pure ore]

I tried doing coroutines checking if my values are not 0, but that just made the audio overlap

[dusk apex]

Using a timer:cs [SerializeField] private float delay = 2f;//Two seconds of delay private float next = 0;``````cs var direction = m_Actions.Player.Move.ReadValue<Vector2>(); Vector3 movement = (transform.right * direction.x + transform.forward * direction.y) * m_MoveSpeed; if (movement.sqrMagnitude > 0 && Time.time > next) { //Play footsteps next = Time.time + delay; } movement.y -= m_Gravity; m_CharacterController.Move(movement);Assuming the sound played isn't looped - not needing to stop it ect

[pure ore]

Why is this happening? The audio source plays the clip even when im not moving

float x = m_Actions.Player.Move.ReadValue<Vector2>().x;
        float y = m_Actions.Player.Move.ReadValue<Vector2>().y;
        Vector3 vector = (transform.right * x + transform.forward * y) * m_MoveSpeed;
        vector.y -= m_Gravity;
        m_CharacterController.Move(vector);

        if (vector.magnitude > 0f || (m_Actions.Player.Move.ReadValue<Vector2>().x != 0f || m_Actions.Player.Move.ReadValue<Vector2>().y != 0f))
        {
            if (Time.time < m_NextFootstep)
                return;
            int rand = Random.Range(0, m_FootstepSounds.Length);
            AudioClip clip = m_FootstepSounds[rand];
            m_Source.clip = clip;
            m_Source.Play();
            m_NextFootstep = Time.time + m_FootstepTimerMax;
        }

[dusk apex]

Log the magnitude, x and y values.

Automatically, the y component will be equal to gravity so you'd get some directional play.

[pure ore]

Oh I see

[dusk apex]

Consider doing the above before adding gravity

[rocky basalt]

So I tried this and it was a good lead, almost worked, but it sort of moved slightly diagonally on its local axis, not perfectly along it. I'm not sure why, it was pretty odd. And unfortunately the documentation is basically nonexistent

[blazing smelt]

Alright so I’ve imported an Asset Store package into a project I’m working on, and there are compiler errors that prevent me from making builds. However, I installed said package into a blank project and it works fine.
I presume it’s an issue with how I imported the package, but I’m not sure how to proceed with this. I’ve already tried deleting and reimporting said package, and I’ve also tried deleting and reimporting one of the dependencies (Shader Graph) required for the shader that’s causing the compile errors.
Would any of you have ideas on what else I should try?

[knotty sun]

Care to share the compile errors?

[blazing smelt]

They're errors in a Shader Graph shader. When I imported the package, it initially set the Shader Graph version to 12.1.7 (which wasn't recognised by Unity, so I downgraded to 12.1.6). But the compile errors still existed.
The weird part is I was able to compile previously. But then I switched platforms and the errors popped up, and they persisted when I switched back.

[blazing smelt]

should I ask in #archived-shaders instead?

[knotty sun]

probably best, I can only think it's a render pipeline issue

[blazing smelt]

sure I'll screenshot the mentioned lines of code

[blazing smelt]

cheers I posted there, hopefully someone knows what's what

[cosmic rain]

It looks like GLES3 graphics API doesn't support some of the stuff. Maybe try setting the target graphics API to something different in project - player settings.

Ah, but I see vulkan also has an error

[past raven]

can anyone teach me how to use FindAnyObjectByType

is it the class name i put inside or the object name

i keep confusing myself

where do i find the type of an object

[knotty sun]

the class name is the Type

[past raven]

ook

so what happens when theres multiple scripts attached to an object

does it then have several types?

can i still use FindAnyObjectByType with only one class name

if that's the case

[lean sail]

Did you read the docs? https://docs.unity3d.com/ScriptReference/Object.FindAnyObjectByType.html

It only returns one object, the one you asked for. If you want it to return multiple then the "see also" section lists another method https://docs.unity3d.com/ScriptReference/Object.FindObjectsByType.html
But these methods should be rarely used tbh

[tulip spruce]

Is it ok to use a yt video on how to make a highscore table in unity?

or is it better to make it yourself

[mellow sigil]

Do you know how to make one yourself?

[swift aspen]

why would it not be ok?

[tulip spruce]

No

[tulip spruce]

because it is cheating

similar to using chatgpt?

then I wouldn't have made it myself

if you understand my logic

[vagrant blade]

Where do you expect to pull this unknown knowledge from if you can't use learning resources?

[cosmic rain]

Development is not a game. There is no cheating. That being said, it might be more productive if you learn in the process and not just copy paste blindly.

[thin aurora]

Not the same though

Most Youtube videos actually put effort and research into them, where ChatGPT is a bot that responds with summaries of what it has learned

Therefore ChatGPT is only relevant for very global topics, and as soon as it becomes specific it will not help you properly and you should take it with a big grain of salt

So don't use it for learning, use it for reference

[tulip spruce]

ok

[sudden lantern]

then documentation is cheating too

[tulip spruce]

fair point

[maiden fractal]

of course it's cheating, it's made purely for documentational purposes, not for learning

[naive swallow]

Using a computer is cheating

Write your code out longhanded and mail it to the unity offices where they will eventually compile it for you and send back the machine code for you to solve by hand

[knotty sun]

you may think you are joking, it actually used to work like that (not with unity thank god) in the 'good' old days

[maiden fractal]

Why even cheat with high level coding languages, writing binary code by hand have always been the only right way

[leaden ice]

Why use a computer when you can just write out your registers and perform all of the calculations on paper by hand?

[naive swallow]

Just lay face down in the grass and let your dreams carry you to the game you wanted to make

[steady moat]

Why use paper when you can do all of in your memory.

[latent latch]

imagine having to reinvent the quaternion because someone already did it

[steady moat]

Be the computer.

Hello, I am under Unity 2022.3.44, and I am trying to make a menu with a dropdown except that when the OnValueChanged is triggered in the int argument there is always 0 (the value defined in the event) and not the id of the selected dropdown, what can I do?

[knotty sun]

in the method dropdown for the event there are probably 2 options for your method, you need to use the one under the dynamic list

[dense moss]

Is not this ?

Well that's the one, I don't understand where you're coming from

[knotty sun]

at some point you selected the method SetspeedrunMode did you not?

[north thorn]

I have a question.
A multiplayer game. Turn-based. Asynchronous. Think chess. Game state is stored in a SQL db on the server. Each time a player makes a move the game state is deserialized from db, the move is processed, the results are communicated to the clients, game state is serialized again. This is to facilitate cases such as players making one move per day.
Possible/practical to do in Unity?
Or should only the clients (displaying the fancy 3D chess boards) be implemented in Unity, while the server (that processes actual game logic) be implemented in something else entirely?
Or just ditch unity?

[knotty sun]

unity is fine to just use as a render engine, all of the backend code has nothing to do with unity

[north thorn]

because i thought - i'm not really sure if i'm right - that unity can be used for full stack: namely that if i have a multiplayer game i can make the client and the server both in unity and state syncing will be out of the box
but admittedly i've never really dug in the topic

[knotty sun]

in the scenario you described having Unity as the back end processor adds no value whatsoever

[north thorn]

ok thank you

[quiet kestrel]

Does anybody know why the camera's previousViewProjectionMatrix does not update every frame? I am trying to do a shader effect and it is annoying me that it only updates once even though I am moving the camera.

[leaden ice]

It should update each frame, according to the documentation.

Can you show your code?

[quiet kestrel]

all I am literally doing is a Debug.Log(camera.previousViewProjectionMatrix) on Update()

literally this

[quartz folio]

What value are you changing to expect to see the matrix change?

[quiet kestrel]

I am moving the camera's position and changing it's rotation.

I press play mode, in the editor I move the camera and look at the log, and all I see is the same value being printed over and over

and even when using my controller script for moving the camera it remains unchanging

[turbid summit]

Happy Halloween

[leaden ice]

which object is the script attached to? Is there more than one camera in the scene?

[quiet kestrel]

It's applied to a gameobject with a camera component. And there are several cameras in the scene, 3 of them total.

[leaden ice]

ok then you're probably looking at the wrong camera

you're looking at a camera that isn't moving

[quiet kestrel]

there are 3 cameras on 3 different game objects. The above script is applied to one of the gameObjects with the camera component, only one instance of the above script is present and I am moving the game object with the camera component and script applied but the previousViewProjectionMatrix displays the same value. If you search in the Unity discord server you can tell someone has had this issue before (I did not read an answer on it though)

[leaden ice]

if that's actually the case then it sounds like a bug

I recommend submitting a report

[quiet kestrel]

damn

[ionic grove]

Do you guys know how to maintain velocity of a rigidbody on letting go of LMB when I'm using the below to move it around (on holding LMB)

void MoveObject()
{
Vector3 targetPosition = mesh.position + mesh.forward * detectionRange;

// Use Rigidbody to move the object
objectGrabbed.MovePosition(Vector3.Lerp(objectGrabbed.position, targetPosition, objectMoveSpeed * Time.deltaTime));

}

[spare dome]

you could get the current velocity of the object and store it in a vector3 then use that vector3 under certain conditions like letting go of LMB to set the RB velocity to that vector

[sleek heath]

or use SmoothDamp

[knotty sun]

your Lerp is wrong to start with

[somber nacelle]

yeah that should be a MoveTowards not Lerp

[ionic grove]

I don't see a .MoveTowards with a rigidbody

Am I being a smoothbrain?

[sleek heath]

Vector3.MoveTowards

on the transform

[leaden ice]

Neither Lerp nor MoveTowards are on Rigidbody itself

[ionic grove]

Ah, it's on Vector3, gotcha

It works basically the same so far after replacing it

It doesn't maintain momentum

[spare dome]

so you are trying to make a throw?

[somber nacelle]

well yes because Rigidbody.MovePosition does not use velocity. so once you stop calling that method it stops moving

are you sure you don't want to just be assigning the velocity instead?

[ionic grove]

No, I'm doing a top down where you can pick objects up and they "float" in front of you or rather are "dragged" in front of you. Just want the object to maintain velocity when I let go of it

[ionic grove]

Yeah this seems to be the issue

[spare dome]

you can do this if you do not want to use the velocity of the rb
#archived-code-general message

but you probably could still do the exact same thing with the RB velocity set directly somehow

[ionic grove]

So should I be using the linear velocity to get it to "float" in front of my player? Or should I still be using what I have and just store the linear velocity of it until it's released?

Although I don't think it technically has any until I release it (under my current implementation)

[leaden ice]

You can do either one

[ionic grove]

I'd like to use linear velocity the entire time if possible. Then I can just unassign that RB when I don't want to be holding it and turn on gravity, and, in theory, it should maintain momentum

[sleek heath]

so you want to be able to throw the object?

when you release

[spare dome]

you should probably find a way to use the velocity to get the "float" since it will actually update the velocity, unless you want to calculate velocity yourself in that case that does work

[ionic grove]

No, not throw. But if I'm wagging it left to right and release LMB, I want it to continue in whatever direction it's going

[ionic grove]

I'm using Unity 6, so it's not .velocity anymore

[spare dome]

yes I know

[ionic grove]

I'm trying objectGrabbed.linearvelocity

[spare dome]

linear velocity is the exact same thing

[ionic grove]

Ah ok that's good to know

I wasn't sure which one it was

I can post the solution that worked though

Which was helped by @leaden ice 🙂

void MoveObject()
{
    Vector3 targetPosition = mesh.position + mesh.forward * detectionRange;
    Vector3 expectedPosition = Vector3.Lerp(objectGrabbed.position, targetPosition, objectMoveSpeed * Time.deltaTime);
    Vector3 velocity = (expectedPosition - objectGrabbed.position) / Time.deltaTime;

    // Use Rigidbody to move the object
    objectGrabbed.linearVelocity = velocity;
}

[spare dome]

you can calculate your own velocity yourself by using current position and previous position to get your velocity

yes

you just calculated your own velocity

[ionic grove]

Not sure how I can post that in pretty code though

[spare dome]

[pure ore]

Is there a difference between using a singleton game manager and a static game manager?

[naive swallow]

How would you use a singleton without using static?

[maiden fractal]

I think they mean static class and methods etc.

[latent latch]

I would say the biggest benefit is just being able to renew the instance

easier to control the lifetime of a singleton

[maiden fractal]

Regular classes gets recreated at scene load for example, static fields will keep their values regardless of scenes

[latent latch]

Otherwise effectively similar. Singletons are probably easier to preload though as well as statics only load into mem at first access

[pure ore]

What I mean is ```cs
private static GameManager m_Instance;
public static GameManager Instance
{
if (m_Instance == null)
m_Instance = new GameManager();
return m_Instance;
}

[latent latch]

Actually, there's more to singletons being that they are also on the editor, so you get the benefit of serializing values from it

[maiden fractal]

MonoBehaviours receive unity messages like Update, LateUpdate etc.

[latent latch]

Oh yeah that's a good point too. Anyway, just use the singleton pattern.

[tacit talon]

How do I calculate the angle between two local quaternions like in the image, but in 3D?
I tried using Quaternion.Angle(), but that doesn't work, because the local rotations are using transform.LookAt() and that gives them completely different rotations.
I was also considering finding their common plane using the end-effectors and then calculating the angle between them on the plane, but I have to do this with local rotations, so I'm not sure how to even make the plane...

[cosmic rain]

If both of the rotations are in the same space, them it should work.

[tacit talon]

you mean with Quaternion.Angle?

[cosmic rain]

Yes

[tacit talon]

It doesn't though, in my case, because the LookAt function messes with the other axes

[cosmic rain]

Look at returns a world space rotation

[tacit talon]

but I'm applying it locally

my issue is that quaternion,angle calculates the difference between the two quaternions (if i'm not mistaken)

[quartz folio]

sure, and what's the problem there?

[cosmic rain]

Ah, transform.lookat doesn't return anything. It just rotates the object to look in a direction.

So I'm not sure what you're comparing there

[tacit talon]

the problem is that for, say if there's an arbitrary rotation around an axis I don't care about, quaternion.angle gives me data I can't use.

[quartz folio]

You've not explained what this arbitrary rotation is. If you want to get the angular difference between two rotations then Quaternion.Angle is a way to do it

[tacit talon]

The practical application I'm applying this to is to compute the difference of two body poses in degrees

[cosmic rain]

Then just use Euler angle degrees maybe. Why overcomplicate with quaternions?

[tacit talon]

wouldn't I get the same result there?

[quartz folio]

Can you screenshot what you're trying to compare, because it's impossible to help like this

[cosmic rain]

No, because you can explicitly compare the axis you're interested in.

[quartz folio]

Like is the problem that you have end effectors that are the rotations and you don't know how to get the angle between the bone direction and its effector?

[tacit talon]

The orange dots are the joints and I'm trying to compare two sets. Middle bottom is the hip, middle top the chest, etc.

[tacit talon]

That's what I was trying to do by creating a plane to find the relevant axis of rotation, but I'm not sure how to go about that when I'm in local space

[quartz folio]

Vector3 from = A-B;
Vector3 to = C-B;
Vector3 theta = Vector3.Angle(from, to);

Only in the cases where you want the direct non-reflex angle.

If you have the plane of rotation represented as a normal vector then you can get a signed angle like:

Vector3 theta = Vector3.SignedAngle(Vector3.ProjectOnPlane(from, normal), Vector3.ProjectOnPlane(to, normal), normal);

[tacit talon]

"If you have the plane of rotation represented as a normal vector"

I wish I had this elusive plane 😅 . This is what I'm trying to figure out at the moment.

I have the points of the plane that I need, but the issue is that they are in different local spaces.

maybe if I rotated the end-effector by the local rotation of the joint I'm trying to compare it to.

[cosmic rain]

Why can't they be in world space..?

[tacit talon]

cause they aren't in the same place when compared.

they might even be two different people facing each other for instance

[cosmic rain]

Then transform the points/directions/vectors to the same local space before using them. There are transform and inverse transform methods for that.

[tacit talon]

ok, thanks! I'll give it a look.

[tacit talon]

Isn't this from world space to local space? That wouldn't be what I'm looking for I think, since it would be in the same position, just with the position converted to local space, or am i wrong?

[cosmic rain]

It's both ways.

That's why there's transform and transforminverse

Or inversetransform. Don't remember

And while at that, you should probably be transforming directions, not positions.

[tacit talon]

this is what I mean, if it makes sense. red is what I expect will happen and green is what I want to happen

[cosmic rain]

I've no clue what these colorful lines are supposed to represent

[tacit talon]

the local rotations, with red the transform parent is simply changed, and with green, the local transform of the point is applied.

maybe this helps more, where the dots are gameobjects and the lines are the hierarchy

and then green and red represent the changes I want and expect, respectively, using inversetransform.

[cosmic rain]

If blue and yellow are the directions that you want to compare, then you can do it just like that, without transforming them.

[tacit talon]

how?

[cosmic rain]

By getting angle between them or using dot product

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

[tacit talon]

so that would be something like Vector3.Angle(a.forward, b.forward)

that doesn't work. 😂

worth a try, though

I think it's because it uses the world space direction

[cosmic rain]

Yes, they are. You can transform them to local space if that's the case.

[tacit talon]

Vector3.Angle(obj1.forward, obj1.InverseTransformDirection(obj2.forward))
using this I get some massive angle between them, when it should be 0

[cosmic rain]

Because that calculation doesn't make sense.

You have one vector still in world space and another one transformed to local space

[sonic iron]

can someone dm me and assist me with a bug. It should be simple I am happy to hop in call

is beginner stuff

[tacit talon]

converting them both gave me an even larger number.

ok I think I got it this time

[cosmic rain]

Beginner stuff goes in #💻┃code-beginner

[tacit talon]

converting both to their own local space did the trick

that did not do the trick.

[cosmic rain]

Maybe you can just compare .localRotation. of the bones. It seems like that's what you're trying to do.

[hexed pecan]

Are those ProjectOnPlane's really needed here?

[quartz folio]

https://github.com/Developer-Notes-Extension/Unity-Notes/discussions/284#discussioncomment-3948523

The angle returned is the angle of rotation from the first vector to the second, when treating these first two vector inputs as directions. These two vectors also define the plane of rotation, meaning they are parallel to the plane. This means the axis of rotation around which the angle is calculated is the cross product of the first and second vectors (and not the 3rd "axis" parameter).

The axis provided only determines the sign

[hexed pecan]

Man this is news to me. Thanks

[tacit talon]

can't do that, since I'm comparing two different rigs.

I mean different as in different structure

[cosmic rain]

Why would that make a difference?

You want to compare a bone rotation across the rigs, no?

[celest warren]

guys is a enum basically referring to all of the elements including components?

[cosmic rain]

Regardless of the rig orientation and other bones positions/rotations.

[cosmic rain]

enum is just a type that allows you to specify a list of values.

[celest warren]

oh

i just transitioned to rblx studio lua to unity

[cosmic rain]

Also, this kind of questions go to #💻┃code-beginner

[celest warren]

ok

[tacit talon]

the rigs differ kind of like this.

it's crude

[cosmic rain]

Then what exactly are you trying to compare?

I feel like the issue was not explained properly and we're going in circles wasting time...

[tacit talon]

these are both shoulders, and I'm trying to get the difference between the shoulder angles. I created a system of points with transform.lookat that is supposed to get the gist of both rigs in order to compare them

but the rotations of the points get oddly transformed when using lookat so the only thing that is accurate is the direction.

kind of like this

I think I'm gonna take a break from this and come back to it tomorrow.

Thank you for your help. I appreciate the time you took here and I think I almost got it solved

[indigo verge]

https://hastebin.com/share/zigokohari.csharp

Okay, am I insane, or is this really weird behavior?

I do a for loop over each entry in Bars.

Bars has 4 entries in it. Startistics has 4 entries in it.

I declare a unique Func in each loop. I use "i" (the iteration variable) in that func.

i correctly returns 0, 1, 2, 3 outside of the func. INSIDE the func however, i always returns 4, resulting in an index out of bounds exception.

Meanwhile, assigning a-

I'm an idiot. I literally just figured it out AS I described it.

It was treating i as the same one variable for all four iterations of the func, not new variables for each iteration.

Which is why it was fixed when I created a new variable, "index" for each...

[cosmic rain]

Yes, that's called variable capture.

Hi all,

I'm still struggling with this strangely -- it looks like Unity is still not detecting my gamepad, but more than that, steam is not even opening up the virtual keyboard.

I tried adding a condition to check for steam input devices, but adding this condition is causing the game to crash. I looked at the Player.log file and couldn't make much sense of the error sadly.

I was originally using "both" input systems, but now I'm purely on the legacy system.

If it helps, here is my code:

It looks like it might be too big to use the C# lining

Is there anything that I should take a look at?

Any guidance is appreciated, thank you!

[blazing smelt]

using tutorials isn't cheating, besides if the tutorial itself isn't ai generated you can have more trust that it actually works

[blazing smelt]

actually I should try manually switching it to Vulkan. Because I remember a couple of times I'd get that error but it wouldn't prevent builds from occurring

although why is it using both APIs at once? I thought it would stick to one or the other

[unborn bough]

I've been reading on the "new input system" and i'm a bit confused.
I'm trying to imagine a game where there is like cutscenes and menus etc.

I presume i'd have an action map for controlling my character, and one for controlling menus.
I know i need to enable the actionmap or actions individually.

But since the character probably doesn't want to subscribe to cutscene events, the game manager would know when the player should have control or not and enable/disable the action maps? How does the cinemachine input provider work, it doesn't seem to enable/disable the maps, but still works?

[cosmic rain]

This is such that devices that don't support vulkan(or other graphic apis) would be able to fallback to those that they do support. You can change that in the project settings. You probably have it set to auto, which includes several graphic apis.

[blazing smelt]

yep it's set to auto (I was checking just a bit ago)

the package originally demanded URP/shadergraph version 12.1.7 but my version of unity didn't recognise those, so I had to switch to v12.1.6 of each of those

so I also need to try making a blank project but in a newer version of unity, that recognises v12.1.7

and see what effects that produces

it's possible I just need to update to a new version of unity

or stick with the old version of the package, except that with the new version the performance is way better when it actually compiles properly

[cosmic rain]

Yeah, that's very much possible. Version compatibility is a thing

[broken nest]

I am writing an editor script to speedup some iteration involving several materials. I have exposed a property in the Inspector of type Material, but when I assign values to it with methods like materialInQuestion.SetColor("_BaseColor", Color.red), the changes aren't applied to the material asset. If I attach a renderer to my script and use renderer.sharedMaterial I can apply the changes there and they will stick. My question is, is there any way to get what ever reference Renderer.sharedMaterial is returning without going through a renderer?

[cosmic rain]

Try marking the asset as dirty so that it serializes all your changes back to the file properly.

EditorUtility.SetDirty

[tulip spruce]

my question still haunts me lmao

but yeah you are right

sometimes it is really difficult understanding how the script works in yt videos and they do minimalist exploration

then I am trying mt best to understand it by Google ING

[blazing smelt]

well if you don't know how to make one, it makes sense to use external resources to figure out how to do it

[broken nest]

Yep, that did it. You're a hero!!

[cosmic rain]

Try to understand it by reading the code. You can always ask about hard to understand places in the community.

[tulip spruce]

Yeah I'll do that

Why even bother with interface if abstract methods exist?

I mean if you have a class that doesn't need to inherit from multiple things

Like for example a command pattern; why would you make the Command class an interface and not an abstract class?

I see a lot of people do it and I'm not sure why

[leaden solstice]

You can’t inherit from multiple abstract classes but you can implement multiple interfaces

[maiden heath]

Yes but I'm talking in the context of a class that *doesn't *need to inherit from multiple things

People still use interfaces in that situation

I wanna understand why, is there a benefit to interfaces im missing

[leaden solstice]

Implementing interface is not inheritance, interface just defines what functionality you need, and help you not care about encapsulated details

You don’t have to care if the concrete class is inherited from something or not, as long as the class implements your interface

[maiden heath]

Ok but thats functionally the same as an abstract method

Theyre both "contracts"

[leaden solstice]

If you use abstract class then you are restricting how the concrete class is formed

There is no case you can know “this class will never want to implement other interface”, especially when you are exposing it as public

See how many interfaces int implements

You should instead wonder why would you not use interface over abstract class

Using abstract class is only sensible when you absolutely need to store shared data

[maiden heath]

So theyre very similar

I dont see any major differences then

[maiden heath]

In what way

[leaden solstice]

You are forcing the whatever class that implements your contract to not have other base class than your abstract class

Less flexibility

[maiden heath]

But that is what we want in some cases

Like if we have a Command class for a command pattern

[leaden solstice]

In what case? You don’t want that kind of restriction

You can have ICommand instead

Then user can freely pick base class

In Unity you possibly want MonoBehaviour command

[maiden heath]

But why would you need to implement other interfaces

Im talking in the context of a command pattern

[leaden solstice]

Why not? You don’t know what command class user will have, why restrict?

[maiden heath]

Well, one drawback is that you cant have instance fields or properties in an interface

I needed that for my command pattern so I used abstract classes

The restrictions are virtually unnecessary

[leaden solstice]

Like I said it is only sensible when you absolutely need to store common shared data, and if you need it then go for abstract class?

[leaden solstice]

You can have properties btw, just not auto backing field

[maiden heath]

Oh

Did not know that

[leaden solstice]

They have same root, interfaces are abstract class with no field in IL level

[maiden heath]

I guess I have to research more about interfaces and abstract classes to decide but, until I dont need to implement multiple interfaces, Ill personally stick with abstract classes for now

[maiden heath]

Where can I see the implementation of it?

[chilly surge]

Base class models "is" relationships, while interface models "can" relationships. It's more about how resilient your code is when confronted by future changes, you can easily make something "can" do more (a class can implement multiple interfaces), but if you need to make something "is" multiple thing, you are backed into a corner because C# doesn't have multiple inheritances (nor is multiple inheritance considered a good thing nowadays) and you are forced to do a huge refactor.

Can someone please help me understand this error with the Unity Player Accounts Authentication? We implemented it into one game, works fine.

I'm now implementing it into a second game, and when we call the Unity login page it errors.

The line is await PlayerAccountService.Instance.StartSignInAsync();

There is no variable required, if I fill the option bool as true or false (isSigningUp), it still happens.

URL states:
error=invalid_request&error_description=The+request+is+missing+a+required+parameter+or+is+using+an+unsupported+parameter.

P.S User anon login, user cloud data and remote config are all working, and the client ID has auto filled under the Unity Player Accounts config in Services.

Most appropriate one for the topic

[latent latch]

blender

[warm badger]

i tried with array and a curve modifier with bones, but the modifiers doesn't support in unity

[latent latch]

you don't need modifiers. Just animate it normally

From the video the chain is very much a static animation with no physics

[vast patrol]

how to properly puzzle objects to empty space

[somber nacelle]

what does it mean to "puzzle objects to empty space"

[vast patrol]

if i have 3x3 2d chart or 3x3x3 3d chart

and i may have some object like 2x1 and move it around

how im supposed to scan if all pieces fit

and attach and deattach it

[knotty sun]

maintain your own internal grid of space and check for empty or occupied places in it

[vast patrol]

like the only way of not looping through everything aggressively is to have physical collider of desired size + snap it to the int

which surely is not good

[vagrant blade]

That is not the only way? 🤔

[latent latch]

Rather, you probably want to use modifiers to make things easier for you to animate, but you should be saving all keyframes. Similar idea with IKs. They don't transfer to unity, so usually the idea is making sure they save the in between for each keyframe. Still, it's not always a perfect solution as a lot of these modifiers use blender's physics.

[vagrant blade]

Why do you have to loop over everything? Just check the tiles in which the object is over to verify if it's occupied.

[warm badger]

seems like i have to gather more ideas and a bi experience with blender animation first...kind of i just cant figure out a guided way to do this

[latent latch]

Unity has its own animation package, but it's not something I've needed to use.

but the idea usually is animate in blender, add the physics in Unity

[warm badger]

suppose i am using a cube with some loop cuts and with a curve modifier...now use the curve points to bend the object...now do i save the keyframe?

[latent latch]

You need to save key frames for each bone. Using the example of IKs, if you were to only move the IK you can pretty much animate limbs by saving the IK keyframe, but that's because Blender's physics is what moves everything else regarding the modifier.

[warm badger]

but what if i am using curve modifier with a beizier curve instead of bone weight? is there any way around?

[latent latch]

So if you were to export data with only a few bones moving, Unity can't really interpret that data with the skin mesh render correctly.

[latent latch]

Not entirely sure, but do some testing yourself and move everything a few units, save all keyframes, repeat

[warm badger]

okay, thank you, i will try out things now

[unborn elm]

I have some On destroy events (removing interface from static list etc) and when I quit this trows a bunch of null errors. Is there any point in doing null checks (I useally prefer not to since it can hide bugs) or is there any other way around it?

I can of course refactor and do a manual function that doesnt get triggered when i quit

[leaden ice]

This is what I would recommend.

But the null checks are also a good idea

[unborn elm]

Thank you, hate when you realize that the idea that demands the most work is the best 🙂

But always nice to avoid null checks when you can

When using Camera.RenderToCubemap, why is one of my sides rotated 90 degrees and flipped?

        renderTexture = new RenderTexture(renderTextureSize, renderTextureSize, 0);

        cam = GetComponent<Camera>();
        cam.RenderToCubemap(renderTexture);

[vagrant girder]

idk where necessarily to ask this question but how do I make it so when on different sized monitors it doesnt cut off my view like in this comparison

[maiden heath]

I have a MonoBehaviour StateMachine class, and it has a subclass called CharacterStateMachine that inherits from it.
The CharacterStateMachine has references to states such as WalkingState or RunningState which inherit from a generic State<T> where T : StateMachine class.
StateMachine and its subclasses handle the transitioning to states and such, and each indiviual State<T> has 3 abstract methods: OnStart, OnUpdate, OnChange.

My question is...

1. Should I handle ALL character logic, e.g crouching, jumping, walking, sprinting inside each of the WalkingState or RunningState which inherit from a generic State<T> where T : StateMachine class, or...
2. Should I handle ALL character logic, e.g crouching, jumping, walking, sprinting inside of the CharacterStateMachine class, or...
3. Should I create a new class called Character which handles the movement and passes in data to the CharacterStateMachine class, or...
4. Should I make classes for each type of movement mechanic, such as CrouchController or JumpController to further split up my code?

[latent latch]

CrouchState and WalkState sound fine, otherwise WalkState with substate of Crouch is an idea

[maiden heath]

Hierarchal FSM?
Thats.. complicated

[maiden heath]

So youre saying I should handle all movement logic in the states themselves?

[latent latch]

If you want to write the least amount of logic, ideally you have more substates

[rain crater]

Hey, I'm trying to split a huge monolithic class that I have into a more manageable thing, and I have a question about the placement of NetworkVariables and input management.
Where should I have them?
I can either have all off that in the main class, and just call functions in other classes that do things (for example: main class gets the input for a honk, it changes the network variable too, and just calls the audio class that honk is on)
or I can separate it all into the audio class, so it gets the input for just the honk, it changes the netvar for just the honk and it handles the sound internally. This way other parts of the vehicle don't know about the honking, as it's irrelevant anyways.

Eventually it all comes down to the same effect, but which approach is better and more professional in the long run?

[latent latch]

One problem I do run with making a bunch of substates is similar to the idea of abstracting too much to a single class. You may fall into the problem of wanting to have behaviour that would be considered more unique which goes against the primary behaviour.

[maiden heath]

That is true

[latent latch]

So if movement controls could be considered very similar to many of these other states, much like crouching/walking/running, then those substates could run very little extra logic that modifies the primary state

[open plover]

I don’t get this error in the editor. But I get it with android - ss is from logcat

From the singleton A, I call StartCoroutine(UIManager.instance.ScreenshotWithoutUI)

[wheat elbow]

Hi all,

So I ended up switching over to the new input system, but I'm struggling to understand what is done here:

The plugin I'm using has the following default bindings, so I was thinking of just starting out with that -- however, I'm kind of confused as to how I'll map these.

Is there any way I could figure out whether to use CursorHorizontal, CursorVertical, etc.?

Any help is appreciated, thank you! 🙂

[leaden ice]

Not clear what you'e asking about here.

Are you asking what to map into the input module?

Unless you have a really good reason, it's usually better to just let the input module use the default settings it came with.

[wheat elbow]

Ahh no yes you're right -- I realized I accidentally overwrote the defaults so I just readded the component freshly.

Thanks for the heads up -- will keep this in mind going forward!

[regal basin]

anyone knows how to stop the navmeshagent to stop repathing once it reached its destination?

        RenderTexture renderTexture = new RenderTexture(Screen.width, Screen.height, 24);
        ssCamera.targetTexture = renderTexture;
        ssCamera.Render();

        Texture2D endtex = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
        RenderTexture.active = renderTexture;
        endtex.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
        endtex.Apply();

        ssCamera.gameObject.SetActive(false);
    }```

This works just fine in the editor, but gives a null reference error in the android logcat. I’m thinking it could be because I manually set application.targetframerate to 60

[leaden ice]

On which line?

[open plover]

It doesnt say

[open plover]

This is the error

It was previosly a coroutine with yield return waitendoftheframe

I thought that was the issue so I made it into a void but still the same problem

[leaden ice]

Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Desktop could be a problem, no?

Does that exist on Android?

[open plover]

I dont think so

I implemented that to see if it correctly works on the editor

[open plover]

I commented that anyways before building

Whatever the issue is, it is about that whole rendering thing

It used to work but now it doesnt idk how and why

[leaden ice]

Where does the saCamera reference come from

Maybe that's null

[open plover]

Inspector

[leaden ice]

And "screenshotCam"?

They are the same

Sry

Why two different variables then

I was experimenting with some things

They are the same thing

Not even different variables

Like I said, could setting the fps to 60 be the issue?

[runic island]

Hello! General question for modularity and performance when it comes to creating items in game with similar but some custom logic.

I'm still in the paper-planning stage for this system and would just like to know how other people are handling this before I go making a whole system in code only to re-write it later.

My game has many items of a similar type. Types of axes, types of swords, types of pickaxes, types of spears, etc. My initial thought was to use a state-machine in the PlayerInteraction.cs script. This quickly became messy so I began refactoring and coming up with plans and I'm between two:

Plan 1: Create a 'MainHandEquipment' class to handle high-level logic related to anything that can be equipped by the player in the main hand. Then have each type of item e.g. Axe, Pickaxe, Spear, Food. inherit from this and add basic logic for that category. Then have the specific item, say Stone Axe, to inherit from there.

This seems fairly simple. I'm mainly just trying to keep memory usage and runtime as optimized as possible while allowing for custom logic in some very-late game unlocks the player will get access to.

Plan 2: Use scriptable objects with polymorphism. So basically scriptable objects are highly efficient in unity since the instances exist in the asset database rather than memory. It reduces runtime memory use and will only load when needed. So I THINK this would be the most optimized in theory.

My main concerns and considerations are that some of the very late-game unlocks for weapons and tool variants will have special functionality. The plan 1 of simply having a class hierarchy would allow me to code that right into the item's class data. Maybe I can do this with scriptable objects somehow that I can't think of, or maybe this would present problems in new ways I haven't considered.

Maybe the memory usage concern is negligible, idk. Also I'm only like 6 months into using Unity, so if I have obvious gaps in knowledge I'm sorry. 😅

[lean sail]

The scriptable object route would still require inheritance in the same way as plan 1 if you want to add custom functionality.
Optimization isnt worth considering here, and tbh what you wrote doesnt make much sense. Youd still be creating and accessing instances at runtime related to data from the SO, like how you would in plan 1. Nothing you do here will actually affect performance, because this isnt gonna be a main source of your performance issues.

For items it makes sense to go the SO route to declare values in inspector rather than code. Either way you need some way to attach logic to the SO, inheritance or any other way

[runic island]

I want to collect data analytics on a WebGL build running on a website, thinking of rolling my own simple back end in nodeJS, can I use UnityWebRequests to send data from inside the engine, mouse clicks, time played etc but more importantly actor positions (non realtime) at particular intervals etc.

There's protection for a good amount of data on a hardware level and the browser is sandboxed to prevent you from accessing any user data as far as I am aware but data from within the Unity build.

Edit: sorry this is more of a design question rather than code specific.

[elfin tree]

I have this code that makes a camera render in wireframe, works great, only issue is if I try to remove the component and add it back, the camera no longer seems to render in wireframe unless I pause the editor and press play again, what's wrong?

    public class CameraWireframe : MonoBehaviour {
        void OnPreRender() {
            GL.wireframe = true;
        }

        void OnPostRender() {
            GL.wireframe = false;
        }
    }

(i don't fully understand how this works)

actually it just seems like this script is irreversible

[warm cosmos]

if I want to spawn prefabs in multiple passes, e.g. rocks, trees. etc. and don't want them to intersect

should I add a bounding box to each prefab and use that to check intersections?

[elfin tree]

`seems like i might just need to clear the camera buffer, not sure how yet

[formal wagon]

Is Resources.InstanceIDToObject performant? I assume it's less performant compared to simply holding a reference to the object, but just how bad is it?

[cosmic rain]

Profile and see for yourself

[warm cosmos]

Is it possible to check whether a bounding box intersects any other boxes in general? because so far the unity documentation shows checking with a specific one

I guess I'm hoping that I can leverage unity's built in ways for collision detection

[cosmic rain]

loop all the potential intersections and test.

[cosmic rain]

Then you'll need to use colliders, not bounding boxes.
