hence that <DoStuff>d__64 weirdness

#

so, things I've just figured out:

  • executing an IEnumerator method doesn't run the method at all until you call MoveNext() for the first time
  • Unity calls MoveNext() as part of StartCoroutine
#

now I'm curious where I got this notion from.

#

I'm pretty darn sure I've seen this exact thing happening in the past.

I'm watching Coding With Unity's inventory tutorial and came across an issue where it can't save the inventory because access is denied

hey, hopefully a qucik question:
How do assembly definitions know what to compile to the new dll?
do they take the entire folder the .asmdef sits at, or does it work with namespaces?

heady iris
#

They're folder-based.

#

Anything in the folder or any subfolder is brought into the assembly

#

(unless another asmdef is present in a child folder; it takes precedence)

wide dock
light wraith

namespaces don't matter for asmdef's

im kinda stuck, idk what synthax to use.

its probably because Bounds is nullable in this struct

dusk apex
#

Load scene data is a struct so modifying it's value won't reflect on the value stored in the list.

round violet
#

ah yes

#

i have to set it to a var, then modifiy the var, then set it back to the list item right ?

dusk apex
#

Right. The list item won't change unless you assign to it directly - relative to value types.

LoadedSceneData tempSaveLoadedSceneData = _loadedScenesData[loadedScenesDataIndex];
tempSaveLoadedSceneData.Bounds = bounds;
_loadedScenesData[loadedScenesDataIndex] = tempSaveLoadedSceneData;

The previous would be like... cs int[] nums = {0, 1, 2, 2};//4 elements int num = nums[3];//4th element num = 5;//Will not have any effect on element 4 of numswhere num was the return value from the list

my instantiated prefabs are getting destroyed somehow, I'm trying to figure it out, can someone fact check me: When I instantiate a prefab I have no way of deciding in script which scene it belongs to so it just gets added to the active scene? If I parent it to a dontdestroyonload gameobject will that parented object now also belong to the dontdestroyonload (I guess yes?) and if I unparent it (set parent = null) does it stay as a dontdestroy on load or goes back to the active scene?

Hey guys, I'm a little stumped and need some help. I have code that lets me rotate an object using the mouse, however, I was wondering how I'd get it to always rotate relative to the player's up and forwards vectors. (up for x axis rotation, forwards for y axis). sorry if it's a silly q

dusk apex
#

You'll need to provide more context to get proper suggestions.

latent latch
#

Like, grabbing the player's up and forward direction via its transform?

#

Quaternion.AngleAxis(angle, player.transform.up)

quaint rock
#

try transform.localRotation = Quaternion.Euler(0, 45, 0);

cosmic rain
#

Because localEulerAngles is a struct, so you modify a copy of it, not the one stored in transform.

latent latch
#

also probably this if you don't want to use euler and eventually gimbal lock yourself

Quaternion.AngleAxis(angle, Vector3.up)

So, hello everyone, i was trying to write a simple dungeon generator and im getting really lost
this is the generation code, this seems to work fine https://gdl.space/efasucolup.cs

my main problem comes with checking if a room has generated inside another, i wrote this function https://gdl.space/jigotolodu.cs
Where my room prefabs have a collider like you can see in the first picture
The problem is that even having one room on top of another, the overlapbox returns zero and i really dont know whats happening

I am trying to create a SO container for an abstract class.
The idea being you can create one container to hold the children of the parent class.

How do i store the many child classes of ShapeVisualData in one container?

@rancid frost@median herald It's weird but setting the smoothSpeed to a higher value fixed it

So, i think i fixed my problem by using overlapBox as

var colliders = Physics.OverlapBox(collider1.bounds.center, collider1.bounds.extents, collider1.transform.rotation, room.roomInfo.m_LayerMask);

i think i changed it to what i though should work but it didnt so this works now, thanks for the help everyone, trying to make it work on Start() was an issue as well

I changed 1 to 2

and used yRotation instead of desiredX

#

formula of lerp:
A*(1-t) + t*B
for iteration i, your transform rotation is
Ri=Ri-1 * (1-t) +t*some end point
assume end point is fixed for simplicity also the t
Ri=(Ri-2 * (1-t) + t* some end point)* (1-t) + t*some end point
=((Ri-3 * (1-t) + t* some end point)* (1-t) + t*some end point) * (1-t)+ t*some end point
=R0* (1-t)^i + (t+t*(1-t)+t * (1-t)^2+...)* some end point
find out i such that Ri= some end point ie (1-t)^i=0 and the coefficient of some end point is one

hey, i have a quick question. It's probably me being dumb and not seeing it but;
I am making a 2d point and click game, in which you can move only horizontally. there'll be some npc's around and we'll click on one of them to walk to it, stop when we reach it and then a dialogue will be triggered. Of course for the player to be able to move through other npc's, i thought i should use colliders as triggers. I am now trying to make the player stop moving when it triggers that particular npc but it doesnt stop, reach npc sprite's center and gets stuck. I'd appreciate it if you guys could help me with this one

```no idea, but i think your code should be no compile errors since you cant have access modifier in method
#

{} pairs are important since no one can interpret your code correctly if they mismatched

fair spruce

i am not getting any compiler errors, it doesnt stop when it enters the collider-zone and instead goes right into the target sprite
sorry for the missing }, i cropped the commented out lines on my original code so i may have missed it while pasting here

#

i think it should be simple to stop a sprite moving when it triggers a particular object but i have literally no idea what i may be missing. The system isn't even complicated now.

fervent furnace

using collider is ok but if you stop the movement right after enter:
NPC
player
and you probably want

get the position (center) of NPC and stop when you reach the position

Sorry to interrupt whatever's going on here, but I switched from Facepunch.Steamworks to Steamworks.NET yesterday, and honestly have no idea if I'm doing this right.

Here's my code, I can't tell if I'm using callbacks right now, or actions + delegates (?)
https://hastebin.skyra.pw/ikijawojov.cs

#

Let me give you an example scenario.

Let's say, I call CreateLeaderboard, with the appropriate parameters
The problem is, I want CreateLeaderboard to actually return a SteamLeaderboard, but since i use OnFoundLeaderboard to update the "leaderboard" variable, CreateLeaderboard returns a null SteamLeaderboard, since it's not set yet

#

Apparently using async/await in this case is a bad idea, since using the callback system is apparently "doing that anyway", except it's clearly not. Since Steam docs are in C++, it's hard for me to figure out how, in this case, to return a SteamLeaderboard as if CreateLeaderboard WAS an async function. I just want to return a leaderboard instead of blindly calling CreateLeaderboard as a function inside my code, and having to handle the OnFoundLeaderboard call directly inside the scripts that are calling CreateLeaderboard.

You're setting a weird restriction for yourself

as far as I know i need to add every object to layer

collider have the same parent

i could just do it with `disableCollisionWithParent `
#

but i tried it doesnt work

leaden ice
#

It will work if you follow my advice

timid depot
leaden ice
timid depot
#

nope Ill show you

#

oh wait

leaden ice
#

Please do lol

timid depot
# 
if (part.disableRigidbody)
{
    rigidbody.detectCollisions = false;
    rigidbody.useGravity = false;
}```
#

like this?

leaden ice
#

No

#

Destroy(rigidbody)

timid depot
#

but I dont want to destroy them

#

hide, disable, anything but not destroy

leaden ice
#

It will work best if you destroy

timid depot
#

I know but i cant destroy

leaden ice
#

Yes you can

#

There's nothing stopping you

timid depot
#

look man

#

now it works but I cant detach it

# 
if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit, reachDistance))

detaching code

leaden ice
#

My recommendation as before is to destroy the Rigidbody when attaching, and add it back when detaching

timid depot
#

im pretty sure detaching still wont work

leaden ice
#

What makes you so sure

timid depot
#

hmm weird you're right it works now

#

but I dont want to destroy it beacuse later I wont know mass etc

#

need to save everything in code

pine carbon
#

ui elements are not visible in player mode what do i do

leaden ice
timid depot
pine carbon
#

they are visible in the preview mode tho

leaden ice
timid depot
#

Destroy(rigidbody);

#

im doing it like this right now

leaden ice
leaden ice
# timid depot how?

Something like

[RequireComponent(typeof(Rigidbody))]
public class PhysicsObject : MonoBehaviour {
  float mass;
  Rigidbody rb;

  void Awake() {
    rb = GetComponent<Rigidbody>();
    mass = rb.mass;
  }

  public void DisablePhysics() {
    Destroy(rb);
  }

  public void EnablePhysics() {
    mb = AddComponent<Rigidbody>():
    rb.mass = mass;
  }
}```
#

it's basic data

timid depot
#

yeah I know but its only mass right?

leaden ice
#

might be worth making a portable object like this to pass things around with too:

[Serializable]
public class PhysicsData {
  public float Mass;
  public Vector3 CenterOfMass;
  // whatever else you want 
}```
leaden ice
#

drag?

timid depot
#

thats why i didnt want to destroy it

#

works good thanks for your help!

#

exactly what I needed

warm kraken
#

i have an object pickup and drop/throw system and the only problem i have right now is it looks jittery when i pickup the object and move it around. maybe it has something to do with the camera? this is my script for the camera: transform.localEulerAngles += sensitivity * Time.deltaTime * new Vector3(-y, x, 0); this is my script for pickable object movement while picked up: Vector3 newPos = Vector3.Lerp(transform.position, desiredTrans.position + offsetPos, Time.deltaTime * lerpSpeed);
rb.MovePosition(newPos);. help would be appreciatedx thx

leaden ice
#

MovePosition belongs in FixedUpdate only

#

And interpolation should be enabled on the Rigidbody

warm kraken
#

i have moveposition in fixedupdate. about the interpolation, when i enable it on the rigidbody it jitters even more ๐Ÿ˜„

is there a channel for network stuff?

thanks xd

median sand

is there any way to remeber a value for a float? for example i want to remeber what maxMoveSpeed is then change it and afterwards change it back

dusk apex
median sand
#

wouldnt that change when i change maxMoveSpeed?

cosmic rain
#

No. Value types are copied by value.

median sand
#

ok

warm kraken
median sand
#

u should be using fixed update for physics but that might be why its jittery

#

so idk

anyone knows how to solve PathTooLongException when building project for android? I have long file path support enabled on my windows machine

don't tell me unity doesn't set longPathAware

that'd be stupid

rugged storm
#

im trying to figure out why diaganol swaps are causing this, this is my code for the swap animation, element.position is already set to the final destination

    IEnumerator SwapAnimation(Element element1, Element element2)
    {

        Vector2 startPos1 = element1.transform.localPosition;
        Vector2 endPos1 = element1.position;

        Vector2 startPos2 = element2.transform.localPosition;
        Vector2 endPos2 = element2.position;

        const float swapTimeSeconds = 0.5f;
        float swapclock = 0f;
        while (swapclock <= swapTimeSeconds)
        {
            float dist = swapclock / swapTimeSeconds;
            element1.transform.localPosition = Vector2.Lerp(startPos1, endPos1, dist);
            element2.transform.localPosition = Vector2.Lerp(startPos2, endPos2, dist);
            swapclock += Time.deltaTime;
            yield return null;
        }

        element1.transform.localPosition = endPos1;
        element2.transform.localPosition = endPos2;
        yield return null;
    }```
warm kraken
#

so thats not the issue

median sand
#

i think fixed update makes them jittery

#

but u need to use it

#

might be a work around though

cosmic rain
warm kraken
#

my cam rotation is in update yes, because its not a rigidbody?

cosmic rain
#

Jittering means that the movement doesn't happen at the same rate as rendering does.

somber nacelle
#

obligatory: use cinemachine for camera controls
less chance of ending up with shit/stuttery cameras

warm kraken
#

gotcha, but would it be a good move to put nonrigidbody/physics object position update in fixedupdate?

cosmic rain
#

No, unless you want them to move at fixed rate. You would need to implement a custom interpolation to avoid such jitter though.

# fervent furnace looks like the swapping animation for one element not prefect how you get the el...

element 1 and 2 are passed in here

#

not much i can help, you have to log the values first to see what lerp returns
also when the size of the grid cell is not one the squares will misplaced

rugged storm
#

hmm it seems to be running 3 times for some reason ill have to investigate more

fervent furnace
#

how you get the end point and start point? by getkeydown and up (or something equivalent)?

#

raycast when key down to get start point and another raycast when key up to get end point

rugged storm
#

yeah i call it in a method that gets run when Input.GetMouseButton(0)

#

i think i see how to fix now

fervent furnace
#

btw if you want to continuously swap the element in path eg
A-->BCD
BCDA
then you need to raycast while moving and probably maintain a state machine in each grid cell....

#

threshold+checking should be enough

rugged storm
#

this is the code

        Vector2Int mousePos = Vector2Int.RoundToInt(mainCamera.ScreenToWorldPoint(Input.mousePosition) - eGridOrigin.position);
       


        if (Input.GetMouseButtonDown(0))
        {
            SelectElement();
        }
        else if (Input.GetMouseButtonUp(0) || (selectedElement != null && (Mathf.Abs(mousePos.x - selectedElement.position.x) > 1 || Mathf.Abs(mousePos.y - selectedElement.position.y) > 1)))
        {
            DeselectElement();
        }
        else if (Input.GetMouseButton(0) && selectedElement != null && selectedElement.position != mousePos)
        {
            if (CanMove(selectedElement, selectedElement.position) && CanMove(elements[mousePos], mousePos))
            {
                 TrySwap(mouseDownPos, mousePos // eventually calls MoveElement

            }
        }

i think i just need to deselect the element on a swap

#

Tryswap already returns a bool on if it was a successful swap or not infact that I just neglected to use

#

oh wait hold on this issue is unrelated the issue is with where i call Move element and Swap Animation

fluid sorrel
#

What I am trying to do:

I have an FPS gun called the Twin Turbos, the Twin Turbos appear in the weapon Holder in each unity scene with the Unity Starter Assets FPS Controller.
I am making the Twin Turbos fire and getting a sprite fire button to work with the gun firing animation in sync.
I want to be able to move while firing.
I am going to send you some scripts that were on the Twin Turbos the way it worked before was the old way in these scripts.

Before the firing button was not working properly, like I could only move and fire at the same time if I presses, and hold the sprite button and move, and if I move and then press the fire button the gun does not fire.
So, can you help me make the Twin Turbos fire while moving? I think the ray cast is done in the scripts I am going to send to you.

The reload that works with these Twin Turbos guns uses a On Click Function.
So the way I imagine it is, if the player presses the fire button while moving the twin turbos will fire over and over again, so the Twin turbos shoot Animation is playing over and over in the Animation.
If the player presses the fire button for less than a second, at least the Twin Turbo Animation will play at least once (like the left Twin turbos pistol fires and then the right Twin Turbos pistol fires once)
I am hoping someone can help me walk through this on a call and a screenshare in my unity on discord help servers.
I have tried lots of things but no luck.

rugged storm

yup i fixed it, i call move element multiple times and even when try swap fails so i instead had to play the animation in my try swap method when its successful

how can i set the value of a Vector3Int from two int ?

latent latch
#

what's a two int

spice crest
#

like there is no such thing visible in the inspector

night storm
latent latch
#

If you mean Vector2, then you just make a new Vector3 and insert the x and y

sacred sinew
#

ok thx

night storm
#

u gotta drag all 20 slots into that array

#

or make code that does it automatically

latent latch
#

John is probably right and you should always be debugging your code here such the slots are set because for all you know nothing is happening in your loops even if the code is correct

#

so start throwing out more loggings because it's easy to be fooled by editor stuff

night storm
#

@spice crest if you want to do it automatically then in the Start method of ItemSlot add this: inventoryManager.ItemSlots.Add(this); (turn it into a list for this to work btw. also its just an example, u dont have to do it this way)

#

cuz currently ur deselecting everything in that list, but that list is empty

spice crest
#

i dragged them btw

#

into the array in inventory manager

#

im still experiencing the same stuff

#

you mean like this amirite?

night storm
spice crest
#

i did it after you said

night storm
#

check if ItemSlot[i].selectedShader.SetActive(false); is even getting called

#

@spice crest is it getting called? did u check it with a debug.log

can I somehow load it from different folder

No.

ok

unless it's a Resources folder

#

read the page I just linked

it explains everything you need to know.

timid depot
#

I know but Im asking maybe there is different function

heady iris
#

You cannot load an arbitrary asset in the built game by name.

night storm
#

isnt it better to just assign the material in the inspector

heady iris
#

it would make a lot more sense to just reference the material directly, yes

I cant assign it to like 500 screws

Weird question

#

Through code, can you disable any component ?

night storm
heady iris
#

No, but you can disable any Behaviour

#

Component doesn't have an enabled property

round violet
#

For example, the rigidbody doesnt have the checkbox in the inspector

#

So can it be disabled in code

night storm
#

i thought by components he meant MonoBehaviours attached to a gameobject

heady iris
#

Rigidbody is an example of something you can't disable. You can make it kinematic, though

round violet
heady iris
round violet
#

Like, what makes them not disablable

#

For i.e
Why can i disable Animator Controller, but not Rigibody

sacred frost
#

unity probably decided it was for the best for the rigidbody for example

#

maybe lead to some issues

round violet
#

Yeah probably

sacred frost
#

but i dont think theres any definitive reason "why"

round violet
#

So not all Components comes from Behaviour class ?

#

Because Behaviour has the enabled properties

heady iris
#

Object <- Component <- Behaviour <- MonoBehaviour

#

any Component may be attached to a game object

#

any Behavior may be disabled

round violet
#

Okay ty

#

Thats why your script you attach has Monobehavior

#

Because its a component

heady iris
#

yeah

#

Unity requires that all user-defined components derive from MonoBehaviour

#

at least, that's what they say...

To do multiplayer, you do need good debugging skills. It will get confusing fast for what code runs where

cerulean kettle
#

I figured out what the issue is

#

Im pretty sure anyway, the issue is that when the script starts up on the client side because the client starts second and the host is not the owner on the clients editor the script disables on the hosts side

hi i dont know much about shader editors but i just found out about Amplify. can a shader created in amplify be easily recreated without it?

warm kraken
#

how can i get the prefab instance of the gameObject? i tried PrefabUtility.GetPrefabInstanceHandle, PrefabUtility.GetOutermostPrefabInstanceRoot and they all return something else and i get errors.

leaden ice
warm kraken
#

no ingame

leaden ice
#

in game you can't

#

prefabs don't exist in game really

#

or at least

#

there is no link between an instance and the prefab that it was based on.

#

you will have to track that relationship yourself manually.

#

Either with a field on the instance, or with a separate Dictionary to map them

#

(PrefabUtility is editor-only as well)

warm kraken
#

i think you misunderstood me. i want to get the instance of a prefab which a certain gameObject may be part of. is there a way to do that? because i dont want to mess with transform.getParent cause different prefabs may have different hierarchy structures.

leaden ice
#

Are you talking about an instance of a prefab that you spawned?

#

Are you talking about a reference to a prefab from the project window?

#

What are you talking about exactly?

#

transform.root will get you the root object of the object's hierarchy. Is that what you want?

warm kraken
#

im making a raycast and when that ray hits a gameobject i want to first check if it's a part of a prefab and if it is, then i want to return that prefab. transform.root will return the parent of the prefab will it not?

hello,
i have a problem with velocity in 2d

i want to handle the x velocity with a transform because it ALWAYS has to be a set value without any alterations, but i want to handle jumping with a rigidbody

any idea?

heady iris
#

a bit like Geometry Dash, maybe?

#

where you're constantly moving right

leaden ice
pure garden
#

yes i said always

#

always meaning even in slopes or with added drag

#

isnt that the same as rb.velocity = new Vector2(whatever, rb.velocity.y)

leaden ice
#

In unity 2023+:

rb.velocityX = whatever;

In earlier versions:

rb.velocity = new(whatever, rb.velocity.y);```
warm kraken
leaden ice
pure garden
#

ok the problem now

#

slopes alterate it

leaden ice
# pure garden slopes alterate it

you will need to do some vector math then. Figure out the slope normal and assign the velocity along the projected "right" direction of the slope.

#

use a raycast to get the normal

pure garden
#

alredy did that but still doesn't seem to work

#

idk if i did smth wrong

leaden ice
#

probably

pure garden
#

ok so,

ive got the normal of the slope (-0.71, 0.71) and i apply force at using

rb.velocity = new Vector2(9, rb.velocity.y);

ive also got a bool that tells you if you're on a slope.

now, any idea of what am i supposed to do with it T-T

#

okay wait i think i found out

leaden ice
#

do this only when you're grounded

pure garden
#

ok ill try that rq

somber nacelle
leaden ice
leaden ice
#

so of course it won't print anything

#

What do you want to happen when the button is pressed?

sacred sinew
leaden ice
#

Literally the only thing escape key does is print that log

sacred sinew
#

yep

leaden ice
#

Neither escape nor that log have anything to do with the rest of the code at all

sacred sinew
#

but it doesn't

leaden ice
#

what doesn't

sacred sinew
#

esc didn't print the debug.log

leaden ice
#

is Update even running?

#

Use Debug.Log to find out

#

(put it outrside all the if statements)

sacred sinew
#

it stopped working when i pressed the button

leaden ice
#

sounds like you disabled this script or deactivated the GameObject it's attached to

sacred sinew
#

i've moved the script on another gameobject that doesn't get desactivated and it worked ! Thanks !

hey I know I'm asking a lot but what am I doing wrong here? I created layer mask "Bolts", all bolts have this layer set and raycast dont detect anything

public GameObject GetLookingAtBolt(Camera cam, float reachDistance)
{
    LayerMask layerMask = LayerMask.GetMask("Bolt");
    RaycastHit hit;
    print("Looking at bolt 1");
    if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit, reachDistance, layerMask))
    {
        print("Looking at bolt 2");
        return hit.collider.gameObject;
    }
    else
    {
        return null;
    }
}

public void TryScrewBolt(Camera camera)
{
    GameObject boltGameObject = GetLookingAtBolt(camera, 2f);
    if (boltGameObject == null) return;

    print("Looking at bolt");
}```

Im trying to connect mirror multiplayer server to my game. This is what I have;

using Mirror;
using System.Diagnostics;
using UnityEngine;

public class NetworkManagerScript : NetworkManager
{
    public override void Start()
    {
        base.Start();

        if (!NetworkServer.active && !NetworkClient.active)
        {
            StartServer();
        }
        else
        {
            StartClient();
        }
    }

    public override void OnServerAddPlayer(NetworkConnectionToClient conn)
    {
        GameObject player = Instantiate(playerPrefab);
        NetworkServer.AddPlayerForConnection(conn, player);
    }
}

and my playermovement script:

using UnityEngine;
using Mirror;

public class PlayerMovement : NetworkBehaviour
{
    public float moveSpeed = 5f;

    public override void OnStartLocalPlayer() { }

    void Update()
    {
        if (!isLocalPlayer) { return; }

        Movement();
    }

    public void Movement()
    {
        float horizontal = Input.GetAxis("Horizontal");
        float vertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(horizontal, vertical, 0f) * moveSpeed * Time.deltaTime;
        transform.Translate(movement);
    }
}

Problem is that when I start the game, the player itself is being spawned but also a clone is being spawned, that follows the player. Nonetheless, if I try to connect to the server by starting another instance, it just starts a server and doesnt spawn any player

guys me and my friend are working on a game jam and want to work in the same project. i installed his project from github and opened it in unity but it didn't export the exact version, but only the assets. how can i download the whole thing as it is exactly the same in his computer and work on it?

leaden ice

The assets make up the entirety of the project

#

(scenes are assets)

Hey, I have a question about assembly or missing references. This class doesn't want to show up in my IDE, though it cleary exists and is mono. Is that ExecuteInEditMode blocking it from being seen? It doesn't have an assembly file either which I'm using

image.png image.png
#

This is my assembly setup. iirc it is performant to use this so that unity can selectively recompile

image.png
mossy snow
#

you'll need to give AraTrails an asmdef and reference it from yours if your own scripts are in an asmdef. Weird that it doesn't have one already since it's pretty standard now

pastel halo
#

how do i go about doing that? the ara trails thing has no assembly info and looks pretty rudimentary

#

it's got no compatable assembly or assembly ref

#

i was trying to access some variables but my classes cant seem to see it, though it functions ingame. not sure what else it might be

#

i was thinking it was namespace related too, but removed that and still couldnt see it. usually that fixes other issues

mossy snow
#

I'm going by package content on store btw, use your own paths if you moved it somewhere

pastel halo
#

ok, ya its default pathing. i'll try that now

#

hmm so it'll let me create it at the top level ara folder, but then breaks when i create a second one in editor

mossy snow
#

the one you create in Editor should reference the one in Assets/AraTrail

pastel halo
#

ok i called it "Base" for the one in the main folder and assigned it to the editor asmdef called "AraEditor"

#

ill try assigning the main one now

#

o dang it worked. I don't understand the process though. Thanks for helping though!

#

i'm a bit lost on the setup of assemblies, afaik its just a performance thing, kinda like culling other recompilation features down to just the custom assembly

#

and that things need to be included to be seen, as well as a similar namespace (depending) or with using

#

Hi! I was hoping that someone could help.
I'm trying to create generic objects for my game to make it easier to add some more in the future.
So to do so, I'm using scriptable objects and one of the attributes is a script (The script that will then be attached to the newly created object)
However, some scripts need parameters that can be set inside the editor directly.
For example, if I want to create a "small chest" I want to be able to define its capacity.

Is there a way to automatically extend my SO depending what script is attached to it and show those additional fields directly in the editor?

mossy snow
#

Wouldn't it be easier just to have your SO reference the prefab directly? Otherwise you'll have to write a custom inspector for your SO to do what you want

#

how are you referencing this "script attribute" currently? Almost every time I see somebody attempt it, it's a fail

strong night
#

That was my initial plan. However, I would like the object itself to be used for both the building mode (So showing the sprite with some color filters) and the actual display on the tile map.
So I thought that by doing this kind of super generic system, I could build the final game object from the ground up

#

I made this script

image.png
#

And reference the script like this in the UI

Screenshot_2024-01-27_231900.png
mossy snow
#

yeah so fails++;
MonoScript is in UnityEditor, so unless you #ifdef'd out that Script field and don't use it at runtime, this won't build

strong night
#

Hmm that's shit lol

mossy snow
#

I would just have two fields, a prefab and a prefab variant that you customized for building mode

strong night
#

Yeah I suppose that works

#

I was hoping they'd be a more "Generic" way

#

But I'm overcomplicating at this point

#

I'll do that. Thanks!

hi, hope someone can help me, I'm trying to move a game object to the mouse position, I want to get a similar result to blender's G / move tool, I tried Camera.ScreenPointToRay, and gives pretty good results but the problem is that it needs something to collide with, and also moves forward/backwards, which is not what I want, Camera.ScreenToViewportPoint I believe does exactly what I need, but it moves the object too slowly, doesn't move at the speed of the mouse, what could I do? :[

leaden ice
#

You probably want to use Plane.Raycast to get points on an imaginary Plane

#

Along with ScreenPointToRay to generate the rays for the mouse position

hallow garnet
#

okay, i'll try that, thank you :D

rancid frost

Not sure why...

cosmic rain
rancid frost

there is the shader

cosmic rain

I see. I guess the sorting layers have effect then.

rancid frost
#

only in game view?

cosmic rain
#

There are many things that work only in game view.

#

Scene view and game view are rendered in different ways.

#

It could also be the difference in the scene view camera angle/position

I'm trying to load a tile where enemys are but it shows as black when it's meant to be a purple tile? ```C# defaultTile = Resources.Load<Tile>("Levels/Tiles/Coloured Floors/Coloured Floors_7") as Tile;

rancid frost
#

give ur shader if its a custom one

#

are u using sprites?

#

we need more info @strange scarab

cosmic rain
strange scarab
#

then I set the tile tilemap.SetTile(tileLocation, enemyTile); in a collision function

cosmic rain
#

Do you use it in SetTile somewhere?

strange scarab
#

the default is the colour the tiles are before they get changed and the enenmy tile is purple and playerTile is orange. This does work by the way when I make the variables public and just assign them in the editor.

#

I am setting the tiles when the player/enemy moves over them hence them changing but to black

#

But they don't seem to load properly I'm guessing

cosmic rain
#

Are there any errors?

#

In the console at runtime

strange scarab
#

It doesn't error unless I print what the tiles names are then it causes errors elsewhere in the script and doesn't work

#

I've put the filepath to same ones I used when the they were public so I'm not sure really weird

cosmic rain
#

Is your Levels folder in Resources folder?

strange scarab
#

Oh nvm it is a file path problem as just moved them to resource folder ๐Ÿคฆโ€โ™‚๏ธ Works now

hallow garnet
#

hi, could someone help me? I'm going kinda insane :[
I'm trying to raycast only on a layer, nothing fancy

        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

        if (Physics.Raycast(ray, out RaycastHit hit, float.MaxValue, planeLayer))
        {
            Debug.Log(hit.point);
        }

but it just doesn't work, I literally just made everything on the scene have that layer, but still it won't work, just in case, it's not the ray, I know it is working because if I get rid of the mask argument (I'm a bit new, not sure if "argument" is the right name for what I passed in the method), it works just fine, and the layer is the right layer too, I can't understand what's wrong

A LayerMask type?

hallow garnet

yup yup

quartz folio

why is it static? How do you set it?

rain minnow
#

You can't serialize a static variable . . .

#

Do you assign anything to it in your code bcuz it must be done in your script if it's static . . .

hallow garnet
#

yeah yeah, I set it by using planeLayer = LayerMask.NameToLayer("MovePlaneRaycast");, I just forgot to delete the serializefield

quartz folio
#

NameToLayer returns a layer

#

not a layer mask

hallow garnet
#

oh really?

rain minnow
#

You should show all of your code so we can see everything . . .

rain minnow
quartz folio

If you want to create a LayerMask from code you need to use GetMask

there is not an error prompt

#

it jsut doesnt work as intended

#

i can pick up on object from the ground but it is not visiible in the nventory, i can still click the slott and there is the name, description and quantity of the item, but the image is not there

#

i tried changing the layers but it didn't work

cosmic rain
spice crest
#

the item's sprite is assigned the picture i wanted, yes.

#

if this is what you mean

#

And it's still not visible?

spice crest
#

yeah

cosmic rain
#

I feel like we are talking about different things.

#

Can you record a video where the issue happens? Then pause the game, select the object that is supposed to render the sprite and show it's inspector?

spice crest
#

sure

#

a sec

#

it shows everything except the image

west lotus
#

UI does not work with Sprite Renderers it works with Image components

spice crest
#

theoretically i understand but practically i dont

#

what should i do bro

west lotus
#

Replace the sprite renderer component with a component called Image

cosmic rain
spice crest
#

damn

cosmic rain
#

These white images on the screen. What are you using to render them?

spice crest
#

im using an image component

cosmic rain
#

Are they ItemImage?

image.png
spice crest
#

see it says ItemImage

#

yeah

#

sorry forgot to put on video

cosmic rain
#

Well, where are you assinging the sprite to these images?

#

Pause(not stop) the game during the issue and select that object.

#

Then take a screenshot

spice crest
#

wait something has changed

#

ok so something weird happened the image i wanted to pop out poppen on the bottom right

#

but the description is still on the top left

#

lke it comes out when i select the top left square only

cosmic rain
#

Debug your code. Set breakpoints on where these things are set and see where it enters and why.

spice crest
#

this place determines what the object thal i'll pick up will look like.

image.png
#

for some unknown reason, this part determines what the bottom right slot will look like

image.png
#

but the name, quantity and description that is shown in this part is only visible if the top left square is chosen

cosmic rain
spice crest
#

it shouldn't be at all related to the bottom right slot tho

#

i don't know why it is like that

cosmic rain
#

And what object it's called in.

spice crest
#

im so stuck

#

when i select a slot that ItemSlot and SelectedPanel is called, but the item's image is still irrelevant

#

do you want to check it out in a repo?

#

i really don't understand

cosmic rain
#

No, I want you to do proper debugging. Step through your code.

How does Unity normalizes vectors, exactly? I've created my own Vector-like struct, that uses doubles instead of vectors (space game),

    [Serializable]
    public struct VectorDouble
    {
        public double x;
        public double y;
        public double z;
    }

And now I need a way to limit it's magnitude, and for that I need to normalize it first, I think (idea is to use analog of Vector3 param = ( param.normalized * newMagnitude) ).

# lean sail how come you are using doubles? When you set stuff like position or anything rea...

I'm going Futurama on it, the player doesn't moves the camera, he moves the Universe.
Objects have "true" and unscaled position, which they store in doubles, and every LateUpdate I set their position via script that converts double struct to a normal vector and applies world scale to it, and this script is where I need clamping for my new struct, so all far away enough objects would just hug a sphere around the center of the world.

lean sail
fervent furnace
#

moving entire space is equivalent to moving the camera

lean sail
#

when a chunk is far away enough, just disable/destroy it

thin hollow
#

They're mostly static (well, to be more exact - they move predictably), and I don't think there will be more than 100 of them at the most (probably no more than 50).

Hi! I am trying to create a particle system that is persistent over scenes and doesn't get reset after a scene change. I have tried everything but I can't manage to do it. I just want it to remain the same even after the scene changes to create a smooth transition. Any help or guidance would be much appreciated!

Be aware that accessing renderer.materials will instantiate the materials. If you don't need unique/instanced materials, use .sharedMaterials instead

Is there really no way to change the size of the cursor in Unity? I want the cursor to grow in size depending on how long you hover over a gameobject, but I can't find how to do this anywhere without creating some sort of weird custom UI cursor...

heady iris
# 
renderer.materials[0] = whatever;
#

This does nothing

#

materials makes an array and puts the materials into it

#

but the array isn't something the renderer is actually using

so you're just modifying the array it gave you

then playerInteract is null or playerInteract.vehicle is null

playerInteract.vehicle is null

i tested

how did you test it?

with debug.log(playerInteract);

okay, good

so, nothing in the code you've shown would stop you from calling GetIntoCar() with a null vehicle

Is there some kind of "Static Scriptable Object"? I currently have a static class with a bunch of static methods that I use in several of my scripts. What I would like to to though, is have this static class depend on some files, and when any of them changes, the mono behaviors using this static class method's would also recompile and refresh. I was thinking about using a SO instead of static class and reference those assets inside SO, but I really don't need any kind instances or compies of this SO. Is this even doable? Or do I have to make an SO asset?

stark sinew

stark sinew
#

You want an object to face another object

#

So you pass the direction from one to the other into it

#

I don't understand, rotating the forward axis is exactly what you want to do?!

Mhmmm, nvm, you say you only want to rotate on the global Y axis, but then it's not facing another object...
So you basically want object X to have a up direction that points to object Y? Still the same method to use, just other parameters

#

but only by rotating arround the y axis

#

cause i set up my rig wrong so now x is facing forward

stark sinew
#

Aaaah

#

Then just fix your Rig first?

rocky jackal
#

but ive already set up ik for the legs

stark sinew
#

Also, you can put a second argument into LookRotation, it's definitely the method you want to use

hexed pecan
#

If that's fine then it might be what you want
If you need to use it at runtime then no

spring flame
hexed pecan
#

Ah okay, then try that

stark sinew
hexed pecan
#

That's where the editor wizards reside

rocky jackal
stark sinew
# rocky jackal i didnt notice

Did you even try with LookRotation?
"forward - The direction to look in.
upwards - The vector that defines in which direction up is."

rocky jackal
spring flame
stark sinew
#

^ 100%

#

But even with that messed up Orientation, the method still works if you put the right arguments

#

btw the problem you have, that your model and rig was already done, I think can be solved pretty easily in blender or some tool in the web

#

I don't believe the software as powerful as blender don't have some easy way of rotating model with rigs and animations

rocky jackal
#

i can tjust rotate it 90 degrees i need to rotate each bone by 90 degrees wich isnt really doable since that would also rotate the mesh and you cant rotate them like you want in edit mode

spring flame
#

I don't know blender that much to disagree, but this doesn't sound right. I think you may have not researched your problem good enough and there is a solution right in blender, maybe in export options or whenever

#

for example have you checked "transform" in export options in blender?

#

and "armature"

stark sinew
#

There is an option to tell which direction is supposed to be up

#

And Tutorials how to properly export a mesh for Unity

stark sinew
# spring flame

This, sorry didn't see it's already there.
Also, make sure your Model is at 0/0/0 with scale of 1/1/1 and it may be possible that you want to check Apply Transform

rocky jackal
#

it works now

Hello, is there any great way to get currently first hovered UI Object ?

#

or do I have to use raycasts and check for Images with their raycast target being true?

leaden ice
gray mural
#

I have to find the first Image with its Raycast target being true

#

by "first" I mean the nearest to the user, so the first one to be selected when clicked

#

guess it should be quite easy to do with raycasts

craggy veldt
#

anybody knows if Color.Lerp is doing hue-shifting under the hood or just a normal interpolation?

hexed pecan
#

Pretty sure it is just linear per-channel

craggy veldt
#

oh dayum

hexed pecan
#

You could use Color.RGBToHSV + Color.HSVToRGB to do hue shifting I guess

craggy veldt
#

yeah that's what I usually do

#

Thanks @hexed pecan ๐Ÿ‘

hexed pecan

ive checked if anythings obstructing the button but its fine

Hello, how do I get UI Object via Raycast (or something similar to this)?
Because Raycast just gets objects with colliders

#

I think I might have had a very bad habits from my previous programming background that I transferred over to unity, so please tell me:

  • should I avoid using constructors in unity?
  • should I avoid using static fields?
  • should I avoid using C# events (event+delegate)
  • and should I avoid using interfaces?

if so, why?

#

asking, because I often encounter problems like "whops, did you <do a thing outside of unity lifecycle>? you naughty naughty"

heady iris
#

Constructors on Unity objects can be a problem.

#

They run before Unity can apply serialized properties to the object.

#

so, don't use them on MonoBehaviours and ScriptableObjects.

#

there's nothing wrong with using them on non-Unity objects, though

#

static fields are fine. Singleton patterns are very common.

#

C# events are also completely fine. You might want to use UnityEvent instead if you want to be able to assign event handlers in the inspector, though.

#

UnityEvent is what things like the "On Click" event on Buttons use

#

and interfaces have one major hurdle: Unity won't serialize fields of interface types

#

So you can't do something like this and expect it to appear in the inspector:

# 
[SerializeField] private IWhatever myThing;
#

There are third party tools to let you serialize interfaces. It's a bit obnoxious though.

hexed pecan
#

You said everything I was about to!

heady iris
#

i don't have a gold star emoji so i'll just have to use this instead

#

that is a luxuriously high-quality golden stud

heady iris
#

If you need to be able to pass some values in, you'll just have to make your own "Init" method

#

I do that quite a lot.

#

All of my UI code used to do its work in Start, so my menu took several frames to build

#

it's all synchronous now; everything gets an Init method called on it after it's instasntiated from a prefab

spring flame
#

great answer, much appreciated! thanks ๐Ÿ‘

heady iris
#

IIRC a whole new list is allocated every time you add or remove a listener?

#

(since you can safely add and remove listeners while the event is being fired)

#

But I am not very confident about that.

heya, im trying to add enemy spawning to my project and for that im trying to avoid locations the enemies cant spawn in, obv. but weirdly enough it doesnt work and idk why lol. all the objects it needs to avoid are on the right layer and have a collider and rigidbody, so idk what's going on. can anyone help?

image.png
heady iris
#

the while loop does nothing here, btw

#

the method returns if it detects something

heady iris
frosty sequoia
#

yep

#

even tho enemies are spawning ontop of objects in the Level layermask

Is it weird that this code breaks/stretches windowed resolution instead of using monitor's resolution (when on fullscreen) ?

        if (Input.GetKeyDown(KeyCode.F))
            if (Screen.fullScreenMode == FullScreenMode.Windowed)
                Screen.fullScreenMode = FullScreenMode.FullScreenWindow;
            else
                Screen.fullScreenMode = FullScreenMode.Windowed;
heady iris
#

Argument 4 is minDepth and argument 5 is maxDepth

#

you're passing...Level and Shield

#

If those are layermasks, they can convert to int, which can convert to float

#

so it compiles, but it's nonsense

frosty sequoia
#

ah, right yea ofc

heady iris
#

just get rid of those two arguments

frosty sequoia
#

how can i add multiple layers to the same argument

#

cuz im trying to avoid multiple

heady iris
#

A layer mask can contain several layers.

#

Just check multiple layers in the inspector for the Enemy field

#

(and rename it, since it's no longer just an enemy layermask)

#

maybe call it spawnBlockers

frosty sequoia
heady iris
#

This is also why a layer mask is not the same as a layer ID

# 
gameObject.layer

that's a number from 0 to 31

frosty sequoia
#

right yea, that makes sense

creating a texture2d from raw color bytes, is there any way to set the asset importer to the texture importer so i can get the proper import settings on the texture2d asset?

casting fails

TextureImporter inherits asset importer

This code is throwing exception on line LineRenderer.startColor as null reference
any idea what am i doing wrong?

[SerializeField] private LineRenderer LineRenderer;

    private void Awake()
    {
        LineRenderer = new LineRenderer();
        LineRenderer.startColor = Color.green;
        LineRenderer.endColor = Color.green;
    }

    private void Update()
    {
        Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width/2, Screen.height/2, 0));
        RaycastHit hit;

        if (Physics.Raycast(ray, out hit))
        {
            Debug.Log($"Looking at {hit.collider.gameObject.name}");
            
            LineRenderer.SetPosition(0, transform.position);
            LineRenderer.SetPosition(1, hit.point);
        }
    }

A suggestion that may not be what you looking for, but try if it works and you may use the inbuilt asset importer without any magic: use ppm format instead so generated.ppm. Ah, ppm does not support alpha...

leaden ice
rigid island
fossil steeple
leaden ice
#

and delete your Awake function

odd arrow
odd arrow
spring flame
#

can you extend the texture importer class and annotated it with your target asset filetype?

rigid island
#

or if its null its prob not detecting your asset as correct type

odd arrow
#

it's only like the bare minimum texture2d options that are built into the Texture2D base class

spring flame
odd arrow
#

is it really necessary to save that as like a png and then import that?

spring flame
#

try this and use .png and not .asset

#

just ask chatgpt like I did xd

#

in case of obscure Unity APIs it helps immensely ๐Ÿ‘

odd arrow
#

that's not what im asking about tho, i think it's stupid if the only way you can set the assetimporter of a texture to textureimporter is if you export it as a png and import that

#

maybe im in over my head but that seems convoluted for no reason

rigid island
odd arrow
#

do you mind showing how you do it?

rigid island
#

I did show you, but my usecase is slightly different

odd arrow
#

gotcha

rigid island
# 
  var assetPath = AssetDatabase.GetAssetPath(evt.newValue);

  var textureImporter = AssetImporter.GetAtPath(assetPath) as TextureImporte```
#

are you passing the assetpath after you created it ?

odd arrow
#

did exactly what you did, still null

image.png
rigid island
#

maybe assetdatabase refresh before doing it?

leaden ice
odd arrow
#

ex is NativeFormatImporter

leaden ice
#

maybe it's not a TextureImporter. as will return null if the cast is invalid

odd arrow
#

well yeah that's why it's null

#

bc it's not a textureimporter

#

and i just dont know how to associate a textureimporter with the Texture2D asset i've created

rigid island
spring flame
#

is AssetImporter.GetAtPath even smart enough to determine the correct importer based on the contents? don't you have to save it using a correct extension?

leaden ice
#

Yeah I think the .asset is throwing it off

#

why is the image not an image filetype?

#

(sorry I'm jumping in midway here)

spring flame
#

can you try and in your code asset save not with .asset but with .shader and see if this returns "shaderImporter" or something?

odd arrow
#

because im loading raw rgba32 bytes

#

again here's my code

spring flame
#

and as I assume, unity doesn't know what are those raw bytes, so it takes a nativeAssetImporter

odd arrow
#

the data isnt coming from a png or anything

#

i created a parsing library for a format and im just trying to make the texture2d creation as streamlined as possible

odd arrow
#

does it apply specific importers based on the file extension then?

spring flame
#

that's as far as I know how you define the importers

odd arrow
#

damn that sucks

leaden ice
odd arrow
#

and there's no way to assign it manually?
