Unity Character controller

[glossy basin]

Do the objects in your scene have colliders?

[swift falcon]

Forgive me if were u already asked this but make sure u have the visual studio code plugin installed in ur package manager

and make sure its up to date

[swift falcon]

I'll look for that, thanks. 🙂

And yes storm

[glossy basin]

Alright, so you need to download this package "Visual studio code editor"

its on the package manager

[swift falcon]

They all have box collider2D because its a 2D game

None of them are set to trigger

[glossy basin]

Oh I think you need to add a rigidbody and set it to kinematic on the objects you are colliding with

I faced the same issue but with my own controller

[swift falcon]

I cant add a rigidbody

It says It conflicts with the character controller

[swift falcon]

???

[glossy basin]

I dont really like / use built in character controller

[swift falcon]

Is this it?

[glossy basin]

Yes

[swift falcon]

Yea its already installed tho...

Ok, so it's there and up to date.

theres a .json file u need to check

[glossy basin]

Add it to the objects you want to collide, not the character

[swift falcon]

aaahhh i see

Is there something I need to do on VS's side?

U can try installing the unity whatever its called

U have to do that in vs code tho

[swift falcon]

What, the thing below?

[strong forge]

I've solved it. Since I am calling this function from a websocket running on a Node server, it wasn't running on Unity's main thread, so I had to sync it.

[swift falcon]

The thing that's for Visual Studio and not Visual Studio Code?

[glossy basin]

It seems you need to setup some things on VS code, this video might help https://www.youtube.com/watch?v=1saf4ahn-ek

[swift falcon]

No again Visual Studio and Visual Studio Code are not the same thing

Precisely.

Theres something on visual studio Code Where u can install extensions

Ok.

Install the one thats for unity

DO NOT DOWNLOAD THE DEPRACTED ONE

[glossy basin]

Sheesh, it was beyond my skills, but glad you solved it !

[swift falcon]

itll be grayed out

@glossy basin i told him the same thing lol i was the one that told him to come here lmao

[glossy basin]

@swift falcon may I ask why are you using vs code instead of standard one?

[glossy basin]

lma

did you solve the collision problem?

[swift falcon]

Im trying it rn

And yeah i would say just use Normal Visual Studio its 10x better in my opinion

[glossy basin]

Same

[swift falcon]

That was the one I downloaded long ago, when I first toed into using Unity.

No it didnt work sorry

[glossy basin]

I see, I suggest switching to vs unity Hub suggests to avoid this kind of problems

[swift falcon]

I wanted to use a rigidbody on my player but it causes this weird blur effect

Ive always had this problem in unity

[glossy basin]

Well, built in character controller has its own gravity / collision detection system

its not good for large projects or complex ones which require physics manipulation

[swift falcon]

Anytime i set the camera to follow a rigidbody it does this... I know they work on different intervals FixedUpdate(rigidbody) and Update(camera) hence the camera glitching

[glossy basin]

I would suggest you implement your own, as it is extremely easy

[swift falcon]

I know how to but that still requires a rigidbody for collision

I mean i guess i could actually just do what u said earlier which was a put rigidboy on everything else

Lemme try that without the character controller

[glossy basin]

Alright, try it then

it should work that way

if not, then something must be messed up on your project settings

[swift falcon]

It does

I dont why i didnt just listen lmao u literally gave me the answer. I was just frustrated i guess sorry and thank u

[swift falcon]

I got to 7:26 and didn't find anything mentioning OmniSharp in VSCode.

In my installation.

[glossy basin]

lmao, no worries there mate

[glossy basin]

skip that part then , continue the tutorial

[swift falcon]

k

[glossy basin]

If that setup did not work, then I suggest switching to standard VS, it is ready to use with unity

[swift falcon]

OOOHHHHH I see what this means now!

[glossy basin]

Makes sense

[grave canyon]

anyone able to help me to add paypal payment into my site ?

[glossy basin]

site?

[grave canyon]

its control panel for an game i only need to add paypal into it

[glossy basin]

Oh, sorry mate, cant help you there

[grave canyon]

no worries bro

[wheat plume]

mb

it was just a massive text file that had like 1 billion characters in I think it was arabic

[quartz folio]

@wheat plume do not post random exes

[wheat plume]

k

it was a text file but renamed to .exe

[thin perch]

Hi all, does anyone know what Chrome OS evaluates to in Application.platform ?

i don't see it listed in the public enum RuntimePlatform

[leaden ice]

https://docs.unity3d.com/ScriptReference/RuntimePlatform.html

https://docs.unity3d.com/ScriptReference/RuntimePlatform.WebGLPlayer.html naturally, no?

Oh Chrome OS

not browser?
Probably Linux

[thin perch]

i would assume linux, but seeing that a bunch of android native feature work, i have no clue without a chromebook to test on lol

[gray zephyr]

For monobehaviours that react when a button is pushed, how do I move from polling the button every frame to pushing a buttondown event? does Unity have anything built-in for that?

like I want to get rid of void Update() {if (Input.GetMouseButtonDown()){...}}

[latent latch]

New input system has some tools, but I remember it not having continuous callback, so one way or another you're stuck polling unless you dig around the forums for some custom fixes.

If someone wants to correct me on that, but probably better to ask in #🖱️┃input-system

[vagrant blade]

The new input system is event based, yes. So it happens when the button is pushed, and you don't have to check it in Update as with the old system.

[swift falcon]

how do i get an input fields text as a variable string

[swift falcon]

So now, after a lot of other downloads (thanks to Visual Studio telling me of different packages to download one at a time and me unticking the option that used only the newest .NET SDK), it finally works. 😄

Thanks!

i did public InputField[] usernamee;

[glossy basin]

Sound like it was a nightmare, but Im glad it worked!

[swift falcon]

It was no daydream, for sure. 😛

[glossy basin]

Like retrieving its value and put it into a string ?

[swift falcon]

yeah

exactly

ike i have an input field and uh i want it to be their username they type in their username and in the script it sets the string variable to waht they typed

[glossy basin]

just on the update function use myString = myInputField.value.ToString();

[junior aurora]

anyone know resources i can look for to make a 2d world where it can be very large and have things like trees, or villages on them?

[swift falcon]

it says input field does not have a definition for value

@glossy basin

X_X

[glossy basin]

are you defining your input field as InputField[] MynputField; or as InputField MynputField;

@swift falcon

[swift falcon]

uh

idk which one do i use

[glossy basin]

Which one are you using right now

[swift falcon]

idk ive tried multiple

[glossy basin]

My bad, replace .value with .text

that should worl

work

[swift falcon]

it says it has no definition for text either

wait no that worked i think

i hate unity

[full scaffold]

Are you using TextMeshPro?

You need to use TMP_InputField (or something similar of the sort) if you are

[swift falcon]

i got it thanks guys

hey dawgs

which gang are you in

// For single-statement ifs

if (conditional) format = "One Line";
// or
if (conditional)
    format = "Indented Newline";

[simple edge]

I do whatever stylecop/codemaid/jetbrains wants me to do
So that's the latter

I find it's best to leave that work to some arbitrary algorithm than waste my own time on it and still mess it up every so often

It also helps when collaborating, because you enforce one style

[hard estuary]

Mostly the second one, unless there are dozens of similar condition checks with really short lines of code, then join lines together.

[paper heart]

help please?

[merry sequoia]

Show me the code you use to trigger the animation

I think it’s because of how your inputs are handled but I’m not sure

[thin aurora]

if (conditional)
{
  format = "Indented Newline";
}

if (conditional) { format = "Indented Newline"; }

The only right answer answers

[gray zephyr]

Sure hope the compiler optimizes that the same as the others

[thin aurora]

Define optimize

[gray zephyr]

I'm not sure where I heard it but I thought no brackets = faster somehow

[thin aurora]

https://sharplab.io/#v2:CYLg1APgAgTAjAWAFBQMwAJboMLoN7LpGYZQAs6AsgBQCU+hxTjTRAbgIYBO6AZgPb90AXnQAXLgFcApgG4WrAJa901Af1oLWxAEbc68pEwC+ChQAcuizmOmYKernQUEjxU0mNA=

Your code is lowered into a version with brackets. So no, not really

In my opinion leaving out brackets is prone to cause errors, should your one-liner turn into a two-liner, or you end up formatting it in a way that invalidates your if-statement. Since if-statement do not require an explicit body if done wrongly, it can be a cause of quite the bug...

IMO it's also just more readable.

[deep fable]

How could I make an effect like this, where if the player is stationary the camera isn't completely stable but rotates a bit? https://youtu.be/TiwDuqw8ycI?t=13

[rugged plume]

hey i wanted to ask, with wheel colliders, what is motortorque

as in what does it represent

is it speed of the wheel, or the acceleration of the wheel

and assuming i kept the valuje of motortorque the same, would it move at the same speed assuming consistent variables like a flat surface

[tardy agate]

torque is a force, adding torque result in you wheel spinning, with less or more force. so ye it's related to the acceleration in some way

[tardy agate]

if you have constant torque, on a flat surface and with constant drag the speed should indeed be constant

Hi, so I have this function to move a target object with a click and drag input. Works great, however I wan't my object to collide with other object so it can never be inside another object. I used a SphereCast that detects such collision, unfortunately the formula inside that cast doesn't seem to affect my object in any way. Am I doing something wrong? Any ideas?

void TargetMovement()
   {
       if (Input.GetMouseButtonDown(1))
       {
           isTargetMoving = true;
       }
       if (Input.GetMouseButtonUp(1))
       {
           isTargetMoving = false;
       }

       if (isTargetMoving)
       {
           Plane plane = new Plane(Vector3.up, Vector3.zero);
           Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

           if (plane.Raycast(ray, out float distance))
           {
               if (Input.GetMouseButtonDown(1))
               {
                   dragOrigin = ray.GetPoint(distance);
               }
               else
               {
                   Vector3 newPosition = focus.position + (dragOrigin - ray.GetPoint(distance));

                   Vector3 direction = newPosition - focus.position;
                   float distanceToNewPosition = direction.magnitude;
                   float radius = 0.5f;
                   RaycastHit hitInfo;
                   if (Physics.SphereCast(focus.position, radius, direction, out hitInfo, distanceToNewPosition))
                   {
                       newPosition = hitInfo.point - (direction * radius);
                   }

                   focus.position = newPosition;
               }
           }
       }

       focusPoint = focus.position;
   }

[quartz folio]

have you checked whether your cast is hitting anything at all, and where that hit is?

[rugged plume]

thank you for this explanation! i skipped hs physics so i never really learnt about that stuff!!

[tardy agate]

it does hit, I was about to check where just now

[tardy agate]

no worries, there's plenty of short videos about elementary car physics on youtube, you should check that out!

[rugged plume]

about this, is it possible to directly set the torque, it seems doing it through motortorque adds to the torque, whereas id like to try and get a single speed

[tardy agate]

I have no idea as for wheel colliders, but you can probably add torque then clamp the velocity to get a maximum speed if that's what you want

[rugged plume]

yeh thatd probably work

[tardy agate]

seems to hit at the right position. i do notice a subtle movement when it hits. either the formula or the code surrounding it is wrong

[rugged plume]

ohh i know the issue

its my wheel collider setup

[tardy agate]

welp

[tardy agate]

constant torque should work fine too if you have any sort of drag. what are you trying to get exactly? a single speed gearbox? or a maximum velocity?

[rugged plume]

a max speed kinda yeh

like in gear one, only up to 60 speedvalues

and in gear two, only up to like, idk 120 or somethingh

[tardy agate]

really not familiar with wheel colliders but i suppose a mix of changing the torque for each gear and velocity clamp should do the trick.

there's probably a tutorial for that somewhere

[rugged plume]

ill give it a look, there should be 4 sure

[rotund burrow]

i'm looking for advice or good tutorials on 3d pathfinding. i want to implement jumping and flying units, for example, in a space with many floors. right now i have some code from sebastian lague tutorial and a movement system

[tardy agate]

up ⬆️

[plucky inlet]

Did you check navmesh or isnt that an option?

[rotund burrow]

i think it's not an option, i need more control

[trim schooner]

A*

[plucky inlet]

You might want to talkt about what "control" means for you, so people might know what to suggest

ah yea, there is A*, you can try that out

[rotund burrow]

i already have basic a* as i said, i need to know how to best implement it for 3d spaces with verticality and floors

i mean control over ai unit. i have a movement system script which i want to use for ai units (as well as player), but navmesh uses its own thing as far as i can tell

[trim schooner]

Are you using the A* asset from the store? That has docs on how to do it

Where did you mention A*? 🤔

[rotund burrow]

you mean aron pathfinding? i've looked into it but for the 3d aspect you have to pay, and i 'm not sure it's what i need

[plucky inlet]

You can always ask a refund if it does not work out for you

[rotund burrow]

i mentioned sebastian lague tutorial on the a*

[plucky inlet]

You did mention his name, not A* , just for the record 😄

[mystic ferry]

how does energy transfer work on box2D rigidbody collisions? obviously mass plays a role but does the engine also simulate other energy transfer types like heat and sound? Just not sure what actually happens

I know about the impulses on overlap and detecting collisions, but not the energy transfer

[plucky inlet]

Is that a code question?

[mystic ferry]

well adjacently, yeah

[plucky inlet]

rigidbody is always mass /velocity related. There is nothing like heat or sound "energy" in unity because heat wont move things just by being hot

[mystic ferry]

um. Lol

not what I mean. When a collision happens energy is transferred between the two bodies, some energy is lost as heat and sound, friction, etc. just wondering what the depth is here

[plucky inlet]

ahhh, my bad. I thought heat as the source of energy, not the result of a collision

Well there is no heat or sound generation on collision. but you can always use the velocity of colliding objects and some physics knowledge to actually create your own system with resulting values

[mystic ferry]

I’m just trying to understand the base collision system essentially. When two bodies collide is it just based on mass and angle? I just want to be able to predict what a dynamic collision is going to look like

I want to know when I need to use kinematic rigidbodies and when I don’t

[simple egret]

That's a question for the experts in #⚛️┃physics

[azure heath]

Currently trying to use a Physics2D.Boxcast to return an array of touched items, as seen here: https://docs.unity3d.com/ScriptReference/Physics2D.BoxCast.html My code is as follows:

RaycastHit2D[] bashables = new RaycastHit2D[20];
            ContactFilter2D filter2D = new ContactFilter2D().NoFilter();
            if (Physics2D.BoxCast(halfHeight, box2D.size, 0.0f, raycastDirection, filter2D, out bashables, rayLength));

I can't seem to get the parameters to line up right for the version of the function I'm looking for. Can anybody here provide an example of the correct parameters?

[mystic ferry]

are you saying most people don’t know how the physics engine in their own game works?

[simple egret]

Yep

That's not a reason to post in the wrong channel though, even if the person you're talking with knows how the physics engine works

Channels are driven by the subject of the question, not the knowledge of the people

[mystic ferry]

😒

[wary wagon]

Today i discovered that Unity doesnt handle references in serialization and just do everything by value ? How do you serialize graphs of stuffs ?

Should i replace every reference by identifiers and do the linking myself ?

( i am having a graph with backward and forward links and it is triggering depth limits errors in the serialization )

[leaden ice]

That's one option.
Another option is using ScriptableObjects as the graph nodes.

[wary wagon]

Isnt that costy ? I will have LOTS of small nodes

[leaden ice]

Through custom editor scripting you can shove any number of SOs you want into a single asset

Costly? Not really

[wary wagon]

still, that graph will be only editable while in game

[leaden ice]

If it's editable in game only then Unity serialization isn't much help. Unless you're using JSONUtility?

[wary wagon]

I plan to do that at some point yus

oh well maybe that json utility can actually help with references ?

[leaden ice]

Newtonsoft JSON has some support for the kind of referential serialization you want

[wary wagon]

❤️

[leaden ice]

TBH though I often end up serializing identifiers and rebuilding my graphs manually at runtime

[wary wagon]

I think im gonna do it that way too, that way i could use unity serialization and edit the stuff with the editor

(while runing a scene )

[cobalt flint]

When dealing with events:
When I subscribe to an event it is acceptable to be void, but when I unsubscribe it expects a return type of EventHandler, but doing so changes makes either the subscribe or unsubscribe not have a correct path, or a correct return type. What should an eventHandler return?

[neat citrus]

Hi, I use this code to rotate the rigidbody, and it rotates the x y and z axis, but i only want it to rotate x
Quaternion carXRot = Quaternion.Euler(new Vector3(0f, carRB.rotation.y, carRB.rotation.z));
carRB.MoveRotation(Quaternion.Slerp(carRB.rotation, carXRot, 10 * Time.deltaTime));

[elfin tree]

Is it normal that code like this also modifies the prefab itself?
What would be a clean way to avoid this?

[trim schooner]

Get VS to create the method for you. ctrl+. on that SaveFinalStats will create a new method

[wary wagon]

So im doing something like this now to hold my map graph

I have two types, one that handles the serialization with IDs and whatenot

[cobalt flint]

I forgot about that, actually. My problem was I was trying to unsubscribe the wrong way. I had to change it to _saveFinalStats -= SaveFinalStats; since it was of type void

[leaden ice]

I don't recommend the EventHandler pattern for Unity. Too much garbage is generated. I recommend defining your own delegate type (or using Action)

[cobalt flint]

Was trying to call it like a function

Okay!

Will look into that. Ty.

[wary wagon]

Why is unity spaming serialization on my game object that is opened in the editor ? 😮

I do nothing and i see my serialization callback called in loops

[grave geode]

Hey I need some help converting some scripts from an oculus framework to openXR / steamVR anyone know how to do it?

[plucky inlet]

I think you have to be more specific. Either its a job offer, than its something for forums or you just dont know how to read some API calls and convert them, than you can explicitly ask for it with your code snippet attached

[west sparrow]

I also would not convert Oculus to SteamVR. You should be using an abstraction framework to support all devices. You should be coding it for OpenXR specifically in most cases. The XRI isn't great but is improving and is a good starting point.

[grave geode]

I just want to have steam only stuff since the game is for steam nothing else. It works for oculus still using the steamVR library so on so forth, I tried using I still am using openXR for a lot of things but the rig I have is from steamVR

also I made this script like a day ago deleted it by accident now rewriting it it doesn't work?

[plucky inlet]

you might consider some repository to backup your progress first then

[grave geode]

I am using a github repo

[west sparrow]

Click on one of the red outlined items and press Control+. It'll tell you a bit more about why it doesn't work and will let you see if you are just missing a Using statement.

But most likely those functions you are calling don't exist in the class. Maybe you have two 'Hand' scripts? Or you've updated a package?

With XR, you almost always want to use your own namespaces, as you are very likely to conflict with their package names at some point.

[plucky inlet]

you deleted by accident a day ago and now have to rewrite it? Does not sound like backing up 😉

[plucky inlet]

But anyway, if you want to convert your script to OpenXR, you have to figure out what they are doing in steamvr and then just google for that specific behaviour in the docs of OpenXR or any example project.

[plucky inlet]

whatever that should tell me besides that you include the library folder and temp in your git repo which is not a good idea

[grave geode]

We have more then 1 person working on it

[plucky inlet]

We can discuss this in another channel and thread, lets get back to the coding topic

[grave geode]

yeah aha

so found out that the VR FPS System asset I bought had a hand script so I deleted it it almost working but IsGrabStarting isn't

[west sparrow]

I highly doubt that is a method

[plucky inlet]

does the autocompletion give any useful suggestion?

[west sparrow]

But if it is, it would likely return a bool

[grave geode]

Says hand does not contain IsGrabStarting

[plucky inlet]

nah, when you write hand and then . , the autocompletion should suggest you to complete with functions available

[west sparrow]

Right click on Hand, go to definition, and see what alternatives are in the script.

But yeah I'd probably just flick through what is in autocomplete

[grave geode]

Nothing there about IsGrabStarting or any of the sort

[plucky inlet]

can you show the script of the IsGrabEnding source?

And where is that coming from, openXR or steamVR?

[grave geode]

SteamVR

[plucky inlet]

Okay, just to clarify. You want to get rid of steamvr right to convert over to openxr?

[grave geode]

No no so I am converting from oculus to steamvr

Found there is a hand.GetGrabStarting

[plucky inlet]

well that should have been quite obvious in the list 😉 yeah I guess you just have to go manually through the scripts of steamvr and see what fits your needs

[grave geode]

Yeah seams so

[plucky inlet]

also there is a #🥽┃virtual-reality for some more specific vr issues

[grave geode]

Oh didn't know that thanks

thanks you for the help hopefully I can work my way around to get it all to work with steamVR

[elfin tree]

So this code is called from .GetComponent after being Instantiated. It is on a prefab and the quads are all gameobject within that prefab. Why does the prefab get permanently modified when calling the code below, shouldn't it all be instances at that point?

[plucky inlet]

What exactly is modified?

[elfin vortex]

hey guys, I'm working on a project for college using Unity 2D and a friend wants to add a mount to the game. Anyone knows how to do something similar to Yoshi from Super Mario World?

[plucky inlet]

You would set the player either as a child of the mount and control the mount from that point or you would have an empty transform sitting as reference point and you just hardmove your player to that position every frame. I would go with setting the new parent and move the mount so they can share a collider

[elfin tree]

bottomQuad / Bottom Quad (Root) for example

They all started as 1x1

But that's the prefab now

and other quads also permanently moved cause of other code below

[plucky inlet]

Are you using executealways or ineditmode at some point in your script?

[elfin tree]

I don't think so, but maybe the prefab was open when the code was running?

[plucky inlet]

The code will not run inside the prefab if you hit enter playmode unless your code is saying [ExecuteAlways]

[elfin tree]

It does not, but I know in another unity version there was a warning which I could ignore when a prefab was open and pressing play

I'll keep testing and see if it stops happening knowing that

[plucky inlet]

yeah, maybe try to figure out the exact situation where it affects the prefab

[lunar forum]

Anyone have tips/suggestions/links on implementing a master script/scene that tracks game variables throughout the lifetime of the game? Trying to search for it doesn't yield much - probably because I just don't know what search terms I should be using.

[plucky inlet]

Singleton pattern, DontDestroyOnLoad

[lunar forum]

Thanks, I'll look those up

[elfin tree]

On another note by the way, does anyone know why first line doesn't work, but the 2nd block does work?

rotationToApply is not null and the changes in variables are mostly just from tests

also note that this code block happens after everything

[leaden ice]

Why are you using quaternion components as if they were euler angles?

[elfin tree]

Probably because I don't know what I'm doing haha

[plucky inlet]

you make two things here. On one thing, you rotate your object for rotationToApply, on the second line you rotate not just by the rotationApply but also by the current rotation

[leaden ice]

quad.transform.rotation *= Quaternion.Euler(0, rotationToApply, 0);```

this is what you want if you want to rotate on the y axis by rotationToApply degrees

or quad.transform.Rotate(0, rotationToApply, 0, Space.World);

[elfin tree]

And could that work straight on the gameObject instead of on the quads?

That's what's weird, first line has no effect

[leaden ice]

i have no idea what that means

the quads are GameObjects

right?

[elfin tree]

In the code I showed

[leaden ice]

What is "the gameObject"?

[elfin tree]

Yeah they are contained withing the main gameObject lets say

[leaden ice]

and how does that relate to the quads

[leaden ice]

YOu mean they are children of it?

[elfin tree]

and the 2nd code block iterates on every children (quad) instead

[leaden ice]

Well it depends what you are trying to achieve

[elfin tree]

cause first line didnt seem to work

[elfin tree]

yeah!

[leaden ice]

what are you trying to do?

[elfin tree]

I'm trying to rotate the whole thing haha, so the hallway is aligned once procedurally generated

the 2nd code block is a work around for the first line

[leaden ice]

if you want to rotate the whole thing you just rotate the parent

[elfin tree]

yeah which is:

gameObject.transform.Rotate(0, rotationToApply, 0);

[leaden ice]

If that's not working then there's something wrong with your setup

[elfin tree]

okay

[leaden ice]

you'd have to explain the hierarchy

which scripts/components are on which objects

where this code is running

etc

[elfin tree]

Whenever it's done reloading assemblies I'll give it a try

But hallway prefab has some quads which represent the walls

At the root of the prefab there's the HallwayController code which I showed part of above

The prefab is instantiated

and then the method which sizes it and rotates it, for example, is called

[leaden ice]

from where

[elfin tree]

from the room generator

[leaden ice]

can you show this code?

Share the RoomGenerator and the HallwayController scripts

[leaden ice]

recommend changing GameObject hallwayPrefab to HallwayController hallwayPrefab

so you don't need to do a GetComponent

[elfin tree]

ohh i see, thanks

[leaden ice]

could you share the whole script(s)?

Still unclear where the rotation is happening

Ah, yeah missing that part

If that's still unclear I'll do a hastebin

[leaden ice]

I'd prefer the bin

[leaden ice]

can you share the RoomGenerator too?

[elfin tree]

There's currently just what I sent that relates to it, I was using it as a test fixture kinda:

[leaden ice]

so what makes you think the rotation isn't working exactly?

Can you share a screenshot of the hallway prefab, including its hierarchy and inspector ideally

[elfin tree]

Let's see, so I'll start with testing out what you said earlier

I've been waiting on that but I guess it's crashed

But it appeared to have no effect yesterday

But as you said I was using it the wrong way

[plucky inlet]

I constantly run into unity crashing, especially when using plastic scm open besides Unity editor open.

So just force quit and restart

[elfin tree]

.

(1) is without the rotation command
(2) is with the rotation command

gameObject.transform.rotation *= Quaternion.Euler(0, 90, 0);

[leaden ice]

what object amm i looking at here

[elfin tree]

Just to explain what you're seeing, it's two faces of the hallway

In the middle

You can ignore the rest

[leaden ice]

looks like it's rotated to me

notice how the pattern on the wall is different

it's a different wall

[elfin tree]

ah ignore the pattern on the wall, it's something different, lemme see if I can remove it

[leaden ice]

withotut he pattern on the wall what else would we be looking at lol

[plucky inlet]

Maybe show your sceneview with gizmos 😉

[elfin tree]

the two faces, basically it's hallway, and it should face towards the hole

[leaden ice]

yeah

[elfin tree]

okay 1sec

[plucky inlet]

And also the inspector and its rotation values

[leaden ice]

what hole?

this is not a very illustrative image

[elfin tree]

this is what I'm trying to rotate

[leaden ice]

anyway I'm sure you'll find that in the inspector the rotation has changed

[leaden ice]

I thought it has 4 quads

what is this thing

can you show the prefab - and the hierarchy etc

[elfin tree]

yeah it should have 4 but it's messed up lol

[leaden ice]

ok show this same angle

with the gizmo

[leaden ice]

with and without the rotation

also make sure your tool handle rotation is set to local

and position to pivot

[elfin tree]

ah it was global

(1) is with (2) is without

they could be the same images afaik

but they are not

[plucky inlet]

And what about the inspector of your rotation?

are the rotation values changing at some point?

[elfin tree]

(1) without (2) with

i would expect a 90 somewhere if it worked

[plucky inlet]

And the script is on what hierarchy object?

[elfin tree]

root

so afaik gameobject.transform (or .whatever) should be the whole thing, no?

[plucky inlet]

gameObject.transform is the root then, yes

[elfin tree]

it's so weird that it wont rotate then

and that manually rotating the quads instead works

[plucky inlet]

But you are sure, by adding debug.log before and after setting rotation is doing something?

[leaden ice]

can you show the prefab's whole inspector?

[elfin tree]

What am I missing?

But yes, just let me know what to screenshot

[leaden ice]

We are only seing the Transform

[elfin tree]

Ah

[leaden ice]

I want to see evreything else

[plucky inlet]

Oh boy...

[plucky inlet]

you are checking the values in prefab mode

You are not in the running scene! you are in prefab mode 😉

[leaden ice]

ah

yes

twentacle is correct

you should be looking at the instance in the scene

[elfin tree]

The values are the same though

[leaden ice]

but in this screenshot you're looking at the prefab

[elfin tree]

I can do the same screenshot in the scene

[leaden ice]

Also are you sure you're looking at an instance that was created by the room generator script?

and not an instance that was in the scene already, for example

[elfin tree]

Hmm good point, let me make sure

I think it might have to do with that, I made a wrong assumption, it's instantiated twice, so I think it might lose it's rotation at the 2nd instantiation.. will keep testing things

Let's say I modify this variable (hallwayX), it wont modify the prefab itself, correct?

Yeah that was it, thanks a lot

[plucky inlet]

you have to write customcode to actually modify a prefab in prefabmode, otherwise it will always modify a runtime instance

[hard sparrow]

Bit of a long shot, but am trying to convert worldposition to hex cubic coordinate. It seems to work fine when converting from cell position to cubic, but not from world to cubic: cs ``` cs
public static Vector3Int WorldToCubic(Vector3 worldPosition)
{
var cubicX = (Sqrt3 / 3f * worldPosition.x - 1f / 3f * worldPosition.y) / CellSizeX;
var cubicY = (2f / 3f * worldPosition.y) / CellSizeX;
var cubicZ = -cubicX - cubicY;

    int cubicXRound = Mathf.RoundToInt(cubicX);
    int cubicYRound = Mathf.RoundToInt(cubicY);
    int cubicZRound = Mathf.RoundToInt(cubicZ);

    var xDiff = Mathf.Abs(cubicXRound - cubicX);
    var yDiff = Mathf.Abs(cubicYRound - cubicY);
    var zDiff = Mathf.Abs(cubicZRound - cubicZ);
    
    if (xDiff > yDiff && xDiff > zDiff)
        cubicXRound = -cubicYRound - cubicZRound;
    else if (yDiff > zDiff)
        cubicYRound = -cubicXRound - cubicZRound;
    else
        cubicZRound = -cubicXRound - cubicYRound;

    Vector3Int cubicCoordinate = new Vector3Int(cubicXRound, cubicYRound, cubicZRound);
    return cubicCoordinate;
}```cs

this just gives bad results

[plucky inlet]

!cs please 🙂

[tawny elk]

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

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

[hard sparrow]

dont type it, use the cs after your three `when pasting code

cs doesn't work

[plucky inlet]

you have to write 3xcs then, your code and 3x again

3x `

[hard sparrow]

it just doesn't work lmao

you have to press enter after cs

[plucky inlet]

so, back to your issue. Can you explain with some values, what you expect and what is your result?

[hard sparrow]

it's all based on this https://www.redblobgames.com/grids/hexagons/

specifically the 'pixel to hex' part

I even asked chatgpt for code and it gave me the exact same thing I already had lol

It's giving wrong values and not even a unique value for every hex

Whereas if I go from cell position to cubic coordinate, it comes out just fine

Probably no one knows, but figured I would ask

[plucky inlet]

Do you visually display your results so you know, they are wrong?

[hard sparrow]

world to cell to cubic should be correct

but world to cell calculation is the most expensive part so

[orchid bane]

How to fly around an object with DOTween?

[hard sparrow]

Hm, I changed it so instead of dividing by cell size, I just multiplied by 2. And now it gives correct values. No clue why that works

except it isn't quite perfect... ugh, math

I'm trying to figure out why my array is being modified even though it's not a global. Psuedo code looks like this:

public float[] myArr;

Start() {
 myArr = new float[] { 0, 0, 0, 0, 0 };
}

Update() {
  MyMethod(Vector3 pos, myArr);
}

MyMethod(Vector3 pos, float[] arr) {

  for (int i = 0; i < 5; i++) {
     arr[i] -= number;
  }

}

When I log arr in the beginning of MyMethod() it changes between frames, and I'm not sure why because I'm never modifying it at the property level. Seems like it would just continue to be that initial array of 0s Any ideas?

[candid kiln]

Can i adjust the video length or cut my videoclip inside Unity?

[chrome horizon]

What is number? is MyMethod a void or return?

[ionic adder]

are you trying to actually edit the underlying video file? or just simulate it in what the end user sees? you can definitely control the start and end times with a VideoPlayer component

[mellow sigil]

Well you modify the array in MyMethod. Arrays are reference types so the parameter is the original array.

[candid kiln]

I actually want to control the start time and i did it with VideoPlayer. But the problem is i want video to be looped, and i don't want to set start time everytime video resets

[toxic notch]

@chrome horizon It's just psuedo to show I'm modyifing the elements by some value. MyMethod is void

@mellow sigil Ahhhhh

didnt know they were ref in c#

[candid kiln]

I wonder if there is any variable for that in VideoPlayer or VideoClip

[ionic adder]

can't you just subscribe to VideoPlayer.loopPointReached? the subscribing method can set the start time for you

https://docs.unity3d.com/ScriptReference/Video.VideoPlayer-loopPointReached.html

[dense spear]

Hey guys!! So I am working on a camera system which on start will change the FOV of the camera until all the corners of the plane (which would be the ground) is fully visible to the camera. So if any one of the points are yet to be rendered, it will keep changing the FOV.
I have tried playing with the GeometryUtility and also the Bounds. But I dont exactly know how to use them

Like in the pictures below... Regardless of the FOV value at the starting... it will change the value until the plane looks like the one in the 2nd pic

This is how far I have got

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class TestController : MonoBehaviour
{
    public Camera camera;
    public MeshRenderer renderer;
    
    public Plane[] cameraFrustum;
    public float zoomOutSpeed;

    [Space(20)] [Header("Plane Properties")]
    public GameObject plane;
    public Bounds planeBounds;
    public Collider planeCollider;
    public MeshFilter meshFilter;
    
    [Space(20)] 
    public List<Vector3> verticesList;
    [SerializeField] private int verticesCount;


    private void Start()
    {
        Mesh mesh = meshFilter.mesh;
        planeBounds = mesh.bounds;
        GetCorners();
        
        //StartCoroutine(ZoomOutCam());
    }
    
    
    
    private void Update()
    {
        cameraFrustum = GeometryUtility.CalculateFrustumPlanes(camera);
        
        
        if (!GeometryUtility.TestPlanesAABB(cameraFrustum, planeBounds))
        {
            camera.fieldOfView += Time.deltaTime * zoomOutSpeed;
        }

    }

Can someone help me figure this out please😃

Thanks

[leaden ice]

Cinemachine can do this for you automatically

[dense spear]

so does it have the feature to change the FOV automatically?

[leaden ice]

yes

you would use a target group

[dense spear]

coz... I havent explored Cinemachines much since I have never worked on a top down game before

[leaden ice]

and put empty objects on the corners and use them in the target group

Cinemachine is absolutely essential for 99% of Unity games

https://ryanjmccoach.medium.com/cinemachine-keeping-all-objects-in-view-in-unity-67678696f627

[dense spear]

thank you so much for the tip... I will definitely check it out

[regal marsh]

I am getting this message periodically and don't know what to do. I have tried updating my drivers (they were all up to date) and I only have one driver so I can't disable it (I tried, it made everything even worse). Any ideas?

I know this isn't strictly coding but this seemed like the best place to ask.

[simple egret]

Ask in #💻┃unity-talk

[regal marsh]

ok

[hybrid goblet]

how can I say that the on destroy function depends on another gameObject and thus it should destroy the other gameObject after it detroys the one with the onDestroy function?

[plucky inlet]

Just call the destroy method on the other object with a delay instead of trying to run code that has been destroyed

[hybrid goblet]

so I need to add a script to that gameObject which has a coroutine in the onDestory function?

[plucky inlet]

For example, an Invoke of destroy with delay or a coroutine, whatever you prefer

[hybrid goblet]

okay thanks, struggeling with interactable trees atm, I need to replace them in runtime and switch them back after, so the scene isn't empty

[plucky inlet]

Do you need to destroy them or could you just disable the gameobject?

[hybrid goblet]

Well I can't do either, I need my terrain, I switch the terrain treedata for an empty array on run time and then want to switch it back to how it was before

[plucky inlet]

Okay, but you can store the treedata, right?

[hybrid goblet]

Yea

Oh wait I'm dumb, I'm doing that in a seperate gameObject instead of just attaching the script to the terrain which would prevent it form getting destroyed while running the code

Sometimes my stupidity is insane

[cyan rapids]

Hello. Would there be any limitations to or concerns with doing something like this? One issue I ran into is that I can't make a List<Debuff<T>>. My goal is to have all subclasses implment a function that takes itself as a parameter for that function.

public abstract class Debuff<T> where T : Debuff<T>
{
    public abstract void HandleStackAdd(T debuff);
}

public class Poison : Debuff<Poison>
{
    public override void HandleStackAdd(Poison debuff)
    {
        // implementation for Poison...
    }
}

[plucky inlet]

Why cant you make a List exactly?

[cyan rapids]

private List<Debuff<T>> debuffList;
isn't supported unless T is specified

it doesn't compile

[plucky inlet]

Could you work with an interface?

[cyan rapids]

I'm not really sure, I generally try to stick to classes. It might also matter that debuff inherits from some other custom classes and it's a whole chain of things

I could write the same code in every debuff subclass and handle it there manually, but I figured there has to be a better way of doing it that's more maintainable and generic

[hybrid goblet]

works flawelessly now

[hybrid goblet]

your problem is somewhere else

it works

[simple egret]

Well that's because T is defined where you created the list

Try outside that class

[hybrid goblet]

didn't want to create new scripts for this, so I just stuck with creating a instance and calling the hi function with:
Poison p = new Poison();
p.hi();
the functioning code:

public abstract class Debuff<T> where T : Debuff<T>
{
    public abstract void HandleStackAdd(T debuff);
    protected List<Debuff<T>> debuffList;

    protected void initDebuffList() {
        debuffList = new List<Debuff<T>>();
    }
}

public class Poison : Debuff<Poison>
{
    public override void HandleStackAdd(Poison debuff)
    {
        // implementation for Poison...
    }

    public void hi() {
        initDebuffList();
        Debug.Log("Hi");
        Debug.Log(debuffList);
    }
}

[hybrid goblet]

well it obviusly needs to be defined

[simple egret]

That's what their issue is about

Assuming that list is meant to go on, say a player, where it's not defined

[cyan rapids]

Yes, this. I want to make a list of debuffs, which can contain any subclass/type of debuff, in whatever class I need, such as an entity or player. I should have specified

[hybrid goblet]

I thought he wanted to put it into the abstract class

[cyan rapids]

I think I might've found a better way of structuring it all that might work, I need to test it though

[simple egret]

Maybe you could reverse it all, get rid of the generics entirely and inject your entity into the debuff method

[plucky inlet]

good question about the generics. why do you need debuff to be generic when you Inherit from it anyway?

[hybrid goblet]

true it just goes arround in circles an interface or a pure abstract parent class would be better

[plucky inlet]

if you want to divide by types of a debuff, just use an enum for example or let poison inherit from debuff without generic approaches

[cyan rapids]

HandleStackAdd() should be called on a an existing debuff if I try to add a new one of the same type, so I can figure out how to combine them on a per-debuff basis, and that is going to need data from that specific debuff type

Basically the way it is now is:

poison = new Poison(value, duration);
poison.AddTo(entity)
[does this entity already have a posion debuff? if so, I don't need to register to events and all that, I can just tell the old debuff to add X stacks and combine values and stuff, so I call HandleAddStack()]

but, what I realized is it's kind've weird to have a tag handle a method to add itself to an entity like that? so I'm trying something else with a tag list/tag manager thingy

it should work with generics, i just gotta type it out

[plucky inlet]

yeah, just find the enum == the new enum object and if yes, add up

[cyan rapids]

Not exactly, I need to reference data from the other tag to combine them. Not every tag will just do stacks++; they need to intepret any sort of variables the other tag of the same type might have

[latent latch]

I just make my debuff/buff class a non-generic c# class which inits coroutines onto the player mono

[cyan rapids]

that's interesting

if i can get this to work I'll try and share my solution :)

[crisp bronze]

Hi, I'm running into this really odd problem. I have this code:

targetObjects[i].DOMove(endPosition.position, durationOffset).(Ease.Linear).SetLoops(-1).OnStepComplete(() => {
                    currentRenderer = targetObjects[i];
                    Debug.Log("Loop1");
                });

The actual loop seems to work just fine, but the code inside of OnStepComplete doesn't run UNLESS only the Debug.Log line is there. It seems that if I add anything else, the OnStepComplete doesn't actually get called. Has anyone experienced this?

[plucky inlet]

not sure, but if you go with the none generic way, can you still get the GetType() and return the Inheritance from the List then?

so List<debuff> but gettype will return poison if its a inheritance of debuff?

[cyan rapids]

Huh, I didn't really think of that. Does that work like that?

I thought if you have a list of debuffs, and get the type of an item in that list, it'll always return as a "debuff"

[plucky inlet]

It works, jsut teste

[cyan rapids]

Wow, that's crazy, I'll try it

[plucky inlet]

gettype of secondlevel which is inheritance of firstlevel prints out secondlevel in a firstlevel list 🙂

[cyan rapids]

There have been so many times in the past that information would have been useful 😅🤣

Thank you

[plucky inlet]

Very welcome 😄

[mystic ferry]

I have event triggers on my UI used to call PlayHover() for the OnMouseOver callback, but I'm using a singleton for the audio clips which apparently means the event trigger has a null reference at runtime. How do you guys create global OnMouseOver sound effects?

[plucky inlet]

you could check the EventSystem API and some events that get fired, maybe there is one you could use to hook into?

[tidal shadow]

i have these variables, filled in inside the inspector as you can see
so why when i set the layer of my gameobjects, do i get the error "A gameobject can only be in one layer. THe layer needs to be in the range [0...31]"?

[mellow sigil]

Layermask is not the same as layer

[tidal shadow]

then what datatype is layer?

just int?

sortinglayer?

oh yeah it is sortinglayer

nope, that gives me datatype error

[mellow sigil]

Layers are ints

[tidal shadow]

how do i get it nicely in the inspector, to see the actual layer i set it to?

oh wait, i have to follow these numbers right?

[soft shard]

Why would your audio pool singleton need a reference to event triggers? Shouldnt your buttons themselves be pulling a source from your audio pool when OnMouseOver is fired, or any of the relevant IPointerEvents for example:

public class SomeUI : Mono
{
void OnMouseOver()
{
SomeAudioPool.Instance.Play2D(someClip);
}
}

[mystic ferry]

my audio singleton doesn't have references to any event triggers. The UI is instantiated at runtime so the dependency isn't filled and I guess I have to set them manually. Thought I could get away with it but I guess not

instantiating things at runtime is so much more modular and clean but oh my god the boilerplate dependency resolutions drive me insane

[latent latch]

Could be a load order issue, so make sure references that are needed after the singleton is created are in Start() or an init/assignment func

[mystic ferry]

good idea

[rocky hollow]

anyone know why unity crashes everytime i run this bit of code? im creating a map generator that generates a grid of tiles first, then a path through the grid that starts on one side and ends on the opposite side. im not sure if the code is even working properly at all as everytime i run the game unity freezes up entirely https://pastebin.com/DtcfHTQr

[latent latch]

I suggest looking into your while loops as you may not ever be exiting them

[rocky hollow]

im trying to do that yet i cant seem to find specifically which one is causing the issue/ how to stop it

[unkempt sail]

is there a way to set the transform of an object while keeping in mind its bounds for things like teleportations?

[rain minnow]

bounds for teleportation?

[unkempt sail]

lets say I am doing this teleportation with a ray cast, when I do that the ray cast hit will return a point lets say at a wall, when I this teleportation on the player on what ever object, the object might be into the wall it self

how can I still do the teleportation, but not have the object inserted into the wall

[hexed pecan]

Maybe use this instead of raycast
https://docs.unity3d.com/ScriptReference/Rigidbody.SweepTest.html

[unkempt sail]

this would tell me if the teleportation does happen if the object will be intersecting with other colliders, my question is about moving the transform so it doesn't intersect

[hexed pecan]

Pretty sure you can just use the hit.distance from the sweeptest

[rain minnow]

Use an offset when placing the object. The raycast will give you the point of intersection but the object position is based on its pivot — which is typically, in the center . . .

[unkempt sail]

does renderer.bounds return maxs and mins based on rotation, or the identity bound?

[hexed pecan]

Did you even try sweeptest..?

[unkempt sail]

yes

[hexed pecan]

If it hits something, move your character towards the direction.normalized multiplied by hit.distance

Dont use the hit.point

[rain minnow]

Or you can cast from the hit.point (of the wall) outward using the size of the object and if nothing hits, place your object from thr hit.point using your distance as the offset . . .

[hexed pecan]

Its perfect for this use case, unless if I misunderstood what you want

[unkempt sail]

let me try

[buoyant mural]

So I want to check if enemy is facing attack position (the enemy is a plane that drops a bomb) I typed this

            float dot = Vector3.Dot(transform.forward, (destination.position - transform.position).normalized);
            if (dot > 0.7f) { Debug.Log("IS facing"); }

but it only works if X and Y are facing the attack position how can I exclude x position?

[hexed pecan]

I just tested this with a cube and it works flawlesslycs var direction = transform.forward; if (rb.SweepTest(direction, out var hit, 10f)) { Debug.DrawRay(transform.position, direction * hit.distance, Color.cyan, 5f); transform.position = transform.position + direction * hit.distance; }

[unkempt sail]

works great

thank you

[unkempt sail]

this does pose a problem for objects that don't have rigidbodies

[hexed pecan]

You can use CapsuleCast, BoxCast etc. They work similiarly

SweepTest is best when you have multiple colliders on one RB

[buoyant mural]

What's a SweepTest btw? Because in all my years of programming I never heard of it

[hexed pecan]

It basically casts all of the object's colliders towards a direction

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

[buoyant mural]

Ok I understand

[hexed pecan]

Not much different from the other Cast methods

[buoyant mural]

Yeah

[hexed pecan]

The trick is to use origin + direction * hit.distance not hit.point

[buoyant mural]

Hm

[hexed pecan]

So it takes the collider's volume into account

hit.distance is the distance that the collider/rb can move freely

[buoyant mural]

Without colliding?

[hexed pecan]

It moves it to the very point of collision but without overlapping

[buoyant mural]

Oh yeah that's very good

[hexed pecan]

Its useful for sure

[buoyant mural]

Yeah

[mystic ferry]

really strange error here because I'm not destroying anything, and all of my other actions work perfectly fine

[buoyant mural]

And is there any better way to do this?

[mystic ferry]

any idea what could possibly cause this?

[buoyant mural]

Which object does it say is getting destroyed?

[mystic ferry]

when I click on the stack trace it doesn't take me to anything

this is so strange

[hexed pecan]

When exactly do you want it to be valid?

Also is it 2D or 3D

[buoyant mural]

3D. I want to check if plane's Y rotation axis is facing the attack target

[hexed pecan]

Okay you could use Vector3.Angle for example

[buoyant mural]

And I do not want it to be exact so if it's off a bit it should still count as facing

[hexed pecan]

Can use Vector2.Angle actually

[buoyant mural]

In a 3D game?

[hexed pecan]

Yes since you only want horizontal rotation right?

Left-right

[buoyant mural]

Yes

Because if it detects X then the plane is just gonna dive to the attack position

[hexed pecan]

I will show with Vector3 anyway its maybe easier to understand:
-Make a Vector3 that is the plane's forward, but make its Y value zero (so its only on the horizontal plane)
-Make another Vector3 that is the direction from your plane to the target, make this vector's Y zero also
-Check the angle from the first to second vector with Vector3.Angle

[buoyant mural]

Though I think vector2 would be better code

[hexed pecan]

Yep, less extra computation because we only need X and Y (really X and Z)

[buoyant mural]

Yeah I really care about optimization and clean code

[hexed pecan]

You can do the above steps with Vector2, just put the X into X and Z into Y

And forget the "set y to zero" parts

[buoyant mural]

Yeah ok will try

[buoyant mural]

Wait why put Z into Y?

[hexed pecan]

See, Vector3 is easier to understand 😆

[buoyant mural]

Well

[buoyant mural]

It is because I've used it more

[hexed pecan]

Because you only care about the horizontal plane, so you want X and Z

[buoyant mural]

Oh yeah

[hexed pecan]

And if you want to use Vector2 then you need to put the Z into Y

[buoyant mural]

yeah ok

[buoyant mural]

Bro I forgot how to do step 2

Ik how to do it

[hexed pecan]

targetpos - selfpos

[buoyant mural]

oh oh bro

Probably cuz it's 1:45 am lol

I think it worked

Ok it worked

thanks

[torn eagle]

Hey!! I need a hand fixing this code so that it finds a new texture if the resolution is smaller than 256x256

            Texture2D texture = new Texture2D(flower.width, flower.height);
            texture.LoadImage(bytes);
            img.sprite = Sprite.Create(texture, rec, new Vector2(flower.width, flower.height), 1f);
            rt.sizeDelta = new Vector2(flower.width, flower.height);
            texture.Apply();

Alternatively, would there be any way to simply upscale the texture if it were smaller than that resolution as doing so via code seemingly clears the texture

[quasi terrace]

Does anyone know why .unitypackages are included in gitignores (or Plastic SCM's ignore.conf)? They are pretty common in assets from the asset store and these assets might not be able to function until you open up the package. Would it be wise to remove it from my ignore.conf so that I can set up plugins across multiple devices (not just the computer I downloaded the asset from) or should it stay the way it is?

[cerulean oak]

how do I set a MeshRenderer material back to the shared material, after having modified its material (and thus having a material isntance)?

I tried doing

meshRenderer.materials[0] = meshRenderer.sharedMaterials[0]```
Also tried storing the sharedMaterial before modifying the material, and neither of them worked

[hexed pecan]

Did you get a null ref/index out of bounds error or how did that not work?

[cerulean oak]

no

the material is simply kept as an instance

[hexed pecan]

Oh wait

[cerulean oak]

not using the shared material

[hexed pecan]

materials gives you a copy of the array

So you should get it, modify its [0] item, then assign it back

var mats = meshRenderer.materials;
mats[0] = meshRenderer.sharedMaterials[0];
meshRenderer.materias = mats;```

That should work

[hexed pecan]

Here you were just modifying the copy of materials array without assigning it back

[cerulean oak]

still not working

[hexed pecan]

Are you sure that code is actually running

Put a debug log there

[cerulean oak]

it is

already checked

[hexed pecan]

Log the materials[0] before and after

[cerulean oak]

ok setting the sharedMaterial as a property and assigning that works

[hexed pecan]

Does it have only 1 material?

Im curious if it didnt work because it has 1 mat and you were using the array

[cerulean oak]

yes only one material

but using .material didnt seem to work either

[cerulean oak]

actually tried that

meshRenderer.material = sharedMaterial //where sharedMaterial is a field assigned to the material```
works
but
```cs
meshRenderer.material = meshRenderer.sharedMaterial ```
doesnt work

[quartz folio]

why would meshRenderer.material = meshRenderer.sharedMaterial do anything?
Once you have used .material, sharedMaterial is gone, no?

[cerulean oak]

yes, seems like it

[hexed pecan]

Probably because meshRenderer.sharedMaterial doesnt exist anymore after you have overridden it

Or returns the .material

[quartz folio]

Exactly, you override it with material, and then that's all it returns

material is just a fancy property that checks whether sharedMaterial has been instanced yet, instances if it can, and then swaps it

otherwise they're just referring to the same thing

[cerulean oak]

ok now another problem, this was suposed to be a way to improve perfomance but it didnt improve shit

xd

going to sleep now

but for some reaosn having 200 material instances drops the perfomance, but replacing them back with the shared material doesnt recover it?

ok it does

but for like 2ms

[limber agate]

Im trying to make a inventory system, I have a inventory array that holds all the item data and the imaginary slots, but idk how I can pair the lets say 3rd inventory slot UI with the 2 index in the array. (Also the amount of inventory slots determined till the game is ran)

[cerulean oak]

The UI?

[cyan bronze]

Is there any way to auto clear unused reference in Assembly Definitions? Only through IDE?

[neat hollow]

hiya, I'm getting 'using' related errors even thought theses packages are in the project. could the project have been corrupted somehow? : error CS0246: The type or namespace name 'TMPro' / and 'InputSystems' could not be found (are you missing a using directive or an assembly reference?)

[leaden ice]

depends if you're getting these in Unity or just in your IDE

[neat hollow]

in unity unfortunately

[leaden ice]

Then either:

• you have spelled something wrong (InputSystems is not a thing for example)
• you have not installed the appropriate package(s)
• you are using assembly definition files and have failed to include references to those package assemblies in your assemblies.

[neat hollow]

it could be assembly definitions - I set some up for Testing before, as I have TMP and Input System packages installed and using //using UnityEngine.InputSystem; //using TMPro; at start of script

[leaden ice]

If you are using asmdefs then you need to add references to those assemblies in the asmdef in order to use those assemblies in your code that is inside an assembly

[neat hollow]

...ohHH 🙂

..the only one i can find in scene is just says {
"name": "NewAssembly"
}

[leaden ice]

assembly definitions don't exist in scenes

I have no idea what you're looking at

[neat hollow]

ill have to rebuild them - its in my asset folder - watching a tutorial now

[leaden ice]

Assembly Definitions are assets in your asset folder with the .asmdef file extension

[neat hollow]

yes this video explains its well just going throught the steps https://www.youtube.com/watch?v=eovjb5xn8y0&ab_channel=GameDevGuide

..nope still getting same error even thought i added textmeshpro to the definition

[leaden ice]

did you save it

[neat hollow]

yes i'm using plastic and saved scene of course - had to role back the changes and will come back to it another day, looks like will take a lot of research to fix. thanks again

[leaden ice]

Not sure how plastic is relevant exactly...

[split venture]

unity is giving me the incorrect answer?? am i using these wrong?

[leaden ice]

what's with the magic numbers

and what are you expecting here

[split venture]

going to replace them with variables soon just trying to get it to work first

[split venture]

my calculator says its 19.462418

yet im getting 0.35

[leaden ice]

are you in degree mode or radian mode

[split venture]

uhh no idea

[leaden ice]

Mathf.Atan uses radians

[leaden ice]

you should

it's important

[split venture]

advise me

[leaden ice]

^

[split venture]

im assuming degree then

based on my log

[leaden ice]

if you want the same answer on your calculator you should switch to radian mode on your calculator

[split venture]

how do i do that

[leaden ice]

i have no idea

[split venture]

nono i want the same mode

on unity

[leaden ice]

i don't have your calculator

[split venture]

as my calculator

i want unity to get what my calculator is getting

[leaden ice]

[granite nimbus]

is there a more efficient way of converting int3 -> Vector3Int than just new Vector3Int(int3.x, int3.y, int3.z)?

[leaden ice]

is there not an implicit conversion?

[granite nimbus]

no, red underline

[leaden ice]

wait if you actually mean efficiency then this will actually be faster since it doesn't call a method:

Vector3Int a = default;
a.x = myInt3.x;
a.y = myInt3.y;
a.z = myInt3.z;```

if you want to just make it convenient - make an extension method

[granite nimbus]

hmm. why?

[leaden ice]

since it doesn't call a method

[granite nimbus]

oh you edited, ok

[hexed pecan]

Lemme write that down in my micro-optimization notes 📝

[granite nimbus]

but what do you mean method? isn't it a constructor?

[leaden ice]

constructors are methods

they have the same overhead as calling any other method.

[granite nimbus]

do you think I will get more or less than a nanosecond benefit?

[cold parrot]

optimizations like this can go either way, faster or slower, its impossible to tell the effect without benchmarking on the target platform.

[gray zephyr]

alright alright

fellas

private bool _active;
public bool Active
{
    get => _active;
}

or

private bool _active;
public bool Active {get => _active;}

or

public bool Active {get;}

[leaden ice]

private bool _active;
public bool Active => _active;```

this one

[gray zephyr]

👀
I didn't even know that one existed

[granite nimbus]

I think it's just not worth benchmarking at all

[wise hollow]

The shortest one

Easy to read and quick to understand.

Plus looks good in a wall of code

[gray zephyr]

Hmmm... does that still count as a property or is it technically a method now?

[leaden ice]

it's a property

[gray zephyr]

[wise hollow]

Remember kids. The better the code sheet looks the further you will go in ur projects

[deft lake]

Alright so I am working on mouse based movement system for a rhythm game that is a hybrid between audio surf and geometry dash (also intend to add other mechanics from various other existing rhythm games). And the system works great! For the most part that is, see I am running into a issue where sensitivity outside of the editor is much higher than inside the editor, and I cant pinpoint why.

Is it possible you guys might be able to see the problem, or see if it is missing something it probably needs.

This is the script used to handle movement for the player. Dont mind my odd way of organizing the code

[gray zephyr]

before I try to help you
I will not mind but I will question your odd way of organizing code—good code is self-documenting, comments become clutter

second, try adding cs after your ```

it'll make the code highlighted/colored for us to read

transforms cannot be instantiated without creating a dummy gameobject I'm pretty sure

// This seems to be useless but might be needed, I dont really know since the script works perfectly fine without it for some reason

that's a sign that you should remove it from your code so it isn't cluttered

[boreal bone]

also yeah you don't need it

[deft lake]

I probably should, I still dont know however how the hell it works without grabbing the transform.

[boreal bone]

MonoBehaviour already has a this.transform

[leaden ice]

MonoBehaviour automatically has a reference to its Transform through transform

[gray zephyr]

    // Start is called before the first frame update
    void Start()
    {
        
    }```

that was added automatically by Unity, but you 100% don't need to keep it

[cosmic rain]

[hexed pecan]

You are multiplying your forces with deltaTime - thats a no-no

And most likely the cause for the issue you are describing

Also yeah please share the code correctly

[deft lake]

Sorry, this is my first time, actually its the first time im doing any of this, and Im surprised I made something that works.

But yeah so removing the deltaTime should fix the issue?

[hexed pecan]

Forces are already multiplied by deltatime by default

[deft lake]

Really?

Well thats handy.

[gray zephyr]

mmmmm deltatime squared

[hexed pecan]

Though deltaTime, when called from FixedUpdate, returns the fixedDeltaTime which shouldnt change

Remove the multiplication and remember to make your forces about 50x smaller to compensate for that

[deft lake]

The issue persists even after removing them and ajusting the forces.

[hexed pecan]

Yeah after remembering this I became less sure of it being the cause of your problem

[leaden ice]

you're reading moouse deltas in update

then using them in fixedupdate

since they don't have the same cadence, you will discard many Update frames typically per FixedUpdate

to solve this you must accumulate mouse delta in Update

and consume it in FixedUpdate

Vector2 mouseDiff;

void Update() {
  // accumulate mouse motion
  mouseDiff += new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y");
}

void FixedUpdate() {
  // consume accumulated mouse movement
  Vector2 mouseSpeed = mouseDiff;
  mouseDiff = Vector2.zero;

  // continue
}```

For example^

[deft lake]

Maybe I really am not cut out for this if I cant understand how any of "that" works.

[leaden ice]

what are confused about

[dim spindle]

its all about experience

when i start learning something new, i also dont understand how it works

but after a lot of using it, I get it, and then I can use it with ease

[deft lake]

Mainly how the code your presented works, my brain is simple, it doesnt like things that are more complex then what goes up should come down.

I do not like my brain.

[dim spindle]

(this happens ALL the time for me, so dont expect to go without learning new stuff all the time)

[leaden ice]

it's really just about that complex

[dim spindle]

nope. its all experience

[leaden ice]

all it's doing is:

• in update, we're adding all the mouse movement we see into a variable named mouseDiff

[dim spindle]

when you need to actually design a solution to a new problem, thats when your brain comes into play

[leaden ice]

• in fixedupdate, we're using all of that accumulated mouse movement to do our motion

that's all it is

[dim spindle]

but understanding stuff is 99% just experience

[deft lake]

Oh I see, so instead of just dumping the mouse values straight into fixed update, we compile it all into one variable that wont throw away half the input data.

[leaden ice]

yes

exactly

[deft lake]

I will give it a shot. Also thoughts on the rest of the code?

[leaden ice]

otherwise we're forgetting the mouse input from all the frames where there was no FixedUpdate

Osmal's comments on deltaTime etc are all correct

[deft lake]

I get it now.

Alright well I threw those away, so I just need to do the mouse thingy.

[dim spindle]

i think im doing physics wrong since i have not used fixed update once

and i have a player controller

and they can throw stuff

[deft lake]

With this I should be able to remove the / 4 value since I dont need it to slow the sensitivty down

[dim spindle]

but its worked so far lol

[rocky hollow]

im trying to make a script to generate a grid of tiles, then generate a path through that. right now though, it crashes unity everytime and gets stuck looping on the switch statement that determines what tiles are a part of what side of the map. anyone know how to fix it? thx https://pastebin.com/ZeSRA0QQ

[hexed pecan]

Rigidbody or CharacterController?

[dim spindle]

charactercontroller

but throwing stuff is in rigidbody

[hexed pecan]

Ok, as far as I know, CC should be moved in Update

So you should be good on that part

If by throwing you mean single force impulses, its fine to do from Update too

But for continuous forces you wanna go FixedUpdate

[dim spindle]

ok

im good then

[deft lake]

Thank you so much for this! after some tweaking it works perfectly.

[dim spindle]

thank YOU for taking the time to learn this stuff!

🙂

[deft lake]

Why must I be thanked?

[dim spindle]

a lot of people will just copy and paste and come back 20 seconds later with an issue

because they understand nothing about the code

people who take the time to learn are much appreciated here, at least by me 🙂

Hopefully by everyone else too!

[deft lake]

I see, well from what I can tell the code takes my mouse inputs and consoldates them into a variable, I still dont understand fully how it works with Vector2

dealing with vectors scare me, but I am terrified of quaternions, but future mechanics in my game WILL need them

[dim spindle]

In what way? The vector2 is just for the mouse movements in both directions. you can move your mouse up and down, and you can move your mouse left and right

[leaden ice]

You can just think of that vector2 as two regular floats nicely packed together as one variable

[dim spindle]

those are the two values in the vector, just how much you moved your mouse either way

[dim spindle]

yeah, makes math in contexts like this easier

[deft lake]

Oh I see, so I can just pull both X and Y from mouse speed now?

[dim spindle]

yes technically but why

usually you want to keep them together

but it depends on what you are doing

[deft lake]

well I have no reason for mouse Y, it is useless for my game at the time being until a add a feature planned for beta. (that being a arcade style flight element)

what I am using the mouse inputs for is this code (sorry for the mess)

   
// This set of if statements handles left and right movement of the player
        if (Input.GetAxisRaw("Mouse X") < 0) // Checks to see if mouse input is going Left
        {
            rb.AddForce(Vector3.left * -mouseSpeed * mouseSensitivity); // This applies the mouse speed to the player going leftwards
        }

        if (Input.GetAxisRaw("Mouse X") > 0) // Checks to see if mouse input is going right
        {
            rb.AddForce(Vector3.right * mouseSpeed * mouseSensitivity); // This applies the mouse speed to the player going rightward
        }```

[dim spindle]

please use this formatting guide !code

[deft lake]

See I take the X movement of the mouse, and if a mouse moves left, the player moves left, same goes for right

inline code specifically

discord has cool builtin formatting for code, makes it very clean to read

ah you put the cs on a new line i think?

the cs gives it colors lol

[deft lake]

oh alright, i do like my fancy colors

[dim spindle]

tells discord that its C# code

Thank you!

[deft lake]

there

[dim spindle]

interesting

[deft lake]

I made it all not so bad looking.

[dim spindle]

so one thing i noticed, why do you take -mouseSpeed in your left branch?

[deft lake]

Its because even though its being told to apply a left force, it reads the -mouseX input and applys that to left causing it to go right

Thats a confusing sentence

Basically it for some reason applies the negative value going left, which leads to going right, so I had to negative it agian.

Negative-Ception

[hexed pecan]

Its most likely one of those nine while loops that runs infinitely

[dim spindle]

also, i think you can skip the branching with something like this

float direction = mouse_x > 0 ? 1 : -1

and multiply the whole thing by that.
but im not sure if thats desirable over just two bigger branches

[deft lake]

Not sure what branching means.

[dim spindle]

its technically branching but IMO it looks better.

like if cases

and this provides opportunities for less repeating yourself

[mossy vine]

Do you guys have a link to c# tutorials that break down the structure of it?

[dim spindle]

again not sure its desirable here

[rocky hollow]

its the switch statement that checks for what tiles are on a side. i used debugging to figure that out. also this is all on awake so does it matter that there are so many while statements or should i fix it

[deft lake]

Im not sure either, I would hate to have to add needless confusion for something that works using simple to understand systems.

But yea getting mouse speed is very important, as without the mouseSpeed variable in the code, it causes the mouse when moving left or right to act as arrow keys causing the player to move at a set speed instead of with the mouse, but with mouseSpeed it makes the player move faster the faster you move the mouse

[hexed pecan]

If you already know the cause then why ask 🤔

[rocky hollow]

i know whats wrong with it, not how to fix it. sorry i shouldve been more clear

[hexed pecan]

Where does it get stuck exactly?

[dim spindle]

personally i think it looks nicer because it follows DRY (dont repeat yourself) which is a strong programming principle ive seen

[rocky hollow]

it gets stuck repeating the for loop forever. although i literally just fixed that issue by adding a default case, though the path generation does not work and i get an "out of range" error when running the game

[deft lake]

@leaden ice Sorry for the ping, but I would hate to use the code you provided without asking if you are ok with me crediting you in the bug fix help section of the credits.

[deft lake]

I see, umm, what does that mean exactly, sorry for all the questions, this again is my first BIG project.

[dim spindle]

What part are you confused about?

[deft lake]

I was wanting to know what the DRY is for and why it is used.

[dim spindle]

It stands for dont repeat yourself, its a concept used in programming because it general makes things easier to change, to read, etc, and is has the added benefit of being easier to read

imagine if you wanted to make a function to check if a number is even

you could do

bool is_even(int num) {
if (num == 1) return false
if (num == 2) return true
// ... ETC
}

but it would be much better if you just went return num % 2 == 0;

% is modulo btw, its just the remainder of division

[deft lake]

I see, still somewhat confused, but I get the idea.

I will explore the concept later down the line during beta when I refine and rewrite parts of code to be less crunchy.

[buoyant crane]

would be better as
int direction = Input.GetAxisRaw("Mouse X");

[deft lake]

Id rather focus on getting things working with the path of least resistance.

[dim spindle]

not sure how that works

[deft lake]

Ya know, seeing its a prototype and all.

[dim spindle]

DRY is the path of least resistance in a lot of cases because it makes changes WAYYYY easier to make

[buoyant crane]

the ternary would evaluate as false when there’s no input causing it to always go -1

[deft lake]

I cant argue with that then, but that does require I know how to use DRY effectively, which I dont.

[dim spindle]

imagine if you have repeated code referencing the same variable over and over, and you want to change how the variable is used. maybe you want to split it into two variables? if you repeated the code, you have to go through each repeat and change the code that uses the variable

[deft lake]

Alright, so the goal is to not have to go through multiple lines of code to fix the change.

[dim spindle]

yeah again, its experience, once you run into something like the scenario i put above, i would ask somewhere about it or google it, and try to learn it more.

[dim spindle]

one of the goals yep

[deft lake]

Can you provide a example using what I have in my script?

[dim spindle]

again its also a LOT easier to understand when you go back later to read your code and change it

float mouse_velocity = Input.GetAxisRaw("Mouse X");
float move_direction = mouse_velocity > 0 ? 1 : -1;
rb.AddForce(Vector3.left * mouse_direction * mouseSensitivity);

this is an example

im not sure if this snippet works

since i dont have access to your project

also not sure why you have mouseSpeed and mouseSensitivty

also dont mix caps like i did here, it makes it confusing, i just use snake_case on habit, maybe i should stop lol

OOPS i also forgot to add a check at the beginning if its != 0 otherwise it will just try to move always

[deft lake]

I have it so first mouseSpeed is used to allow the player to move along with the mouse, instead of moving at a set speed so long as the mouse moves.

[dim spindle]

OH wait was mouseSpeed that accumulated variable from earlier?

[deft lake]

Yup.

[quartz folio]

If you're converting a delta to a fixed value you should be multiplying by deltaTime

[dim spindle]

this is another example of coding principles, naming your variables clearly so you can understand them again

[quartz folio]

because it's no longer a delta

though I suppose it's AddForce, so uh not sure any more

[deft lake]

Since mouseSpeed gets larger the faster you move the mouse, if I add that value into code it allows the speed of the player to increase with the increase in mouse movement speed.

[dim spindle]

I think mouseVelocity makes more sense

[deft lake]

mouseVelocity? I like that

makes more sense

[dim spindle]

exactly

BUT im not saying you should know all this already

[deft lake]

since speed can mean many things now that I think about it.

[dim spindle]

im just saying this from experience

[dim spindle]

yeah thats why i was confused lol

alr im gonna go do something else now but def feel free to ping, it might just take me an extra minute to respond or something, maybe longer if im extra busy idk

[deft lake]

Here, before you go, I am packing the project file into a zip that you can freely download to test and mess around to further inspect how it works to give further feed back, since right now, I am a one man show working on this.

[dim spindle]

ahhh sorry I dont really tend to download other people's projects, not because im not interested, just because it takes a lot of extra effort to get them set up and opened on my machine

and if i downloaded a whole lot, it would clutter my drive lol

you can record a video maybe, or upload a webgl demo if you know how? it could be worth learning that if you want feedback on controls or something

[deft lake]

Is it all right if I send you a raw build, its fairly small, since it literally looks like this,

[dim spindle]

again im REALLY sorry, im not trying to be rude or anything but with unofficial builds i just have a fear of malicious code NOT SAYING that i dont trust you, just paranoid, i hope you understand

i just dont have a workflow that i trust for testing other people's projects

[deft lake]

Wait unity can be used malicously?

How the hell does that work.

[dim spindle]

anything you can have code with can be malicious

[deft lake]

I dont even know how to make a game that doesnt erase everything as soon as you exit it.

That actually still is a problem I need to address later since Soungates whole premise is based on having a geometry dash style level editor.

[dim spindle]

ok again, im not saying i dont trust you, i just dont trust random executables from paranoia

I hope you understand lol

[deft lake]

Since the game is practically ment to be geometry dash, but 3D mixed with riff racer

[deft lake]

I do, and Im not to worried, more time for me to refine my work and now upload something to make a fool of myself.

[dim spindle]

oh shit i have 3.6k hours in geometry dash lol, never heard of riff racer tho

[deft lake]

uhh, better example, think of audiosurf.

[dim spindle]

here isnt really the place to discuss tho

[dim spindle]

i have seen that yeah

[warm wren]

Did an exe file break your computer or something lol

[dim spindle]

nope

[deft lake]

Yea so my game is just that, and geometry dash combined for a timing based rhythm game with hazards and levels that just look like eye candy and have cool cineamatograhy.

[dim spindle]

probably because im paranoid

[deft lake]

Because seeing the same 80s stylized rhythm racer for every game got boring for me.

[dim spindle]

sounds like a good idea. despite my 3.6k hours in GD i actually dislike the retry model of it, replaying a lot makes me frustrated. but there are tons of people who do like it, so theres that

[deft lake]

Run on a track, hit a few procedurlly generated points, and thats it. Super boring.

[deft lake]

Mine will have more of a health system, so you dont get punished harshly depending on dificulty.

[dim spindle]

this is more of a #archived-game-design topic though

if you dont have any more programming questions you can go there instead

[deft lake]

Good point, carry on over there then?

[dim spindle]

sure but i only really have 20 mins left before i want to sleep

[blissful whale]

how would you guys calculate the distance between player and the door to trigger a sprite change?

I want the door's sprite to change when player is near it

but my brain somehow does not work ☠️

[full scaffold]

what r u envisioning

[blissful whale]

When I get near the door it's sprite will change to this

[full scaffold]

What constitutes as “near”

[blissful whale]

like, around the square I draw?

that near

[full scaffold]

Then do exactly that

There is a very common unity method that checks for not “distance” but overlap, or trigger.

[plucky karma]

I'm in a empty scene and playing this scene still generates garbage allocation - Why? Where is this method being called from?

[swift falcon]

Vector3.Distance

[blissful whale]

This reply worked, even so thanks

[plucky karma]

This looks expensive.

[cosmic rain]

Unity's thread workers pool it seems.

Part of the jobs system

[swift falcon]

Vector3.Distance does basically the same thing and it’s way simpler and probably cheaper

[plucky karma]

What jobs? There's nothing running in a empty scene?

There's no game objects too, not even the main camera.

[cosmic rain]

It doesn't need to run. The infrastructure for the jobs system is part of the core unity functionality. It will run regardless of what you have in the scene.

[blissful whale]

Yeahh, it returns alot of errors too

[plucky karma]

Probably because you don't have a gameobject called "Player" in your scene anywhere.

[cosmic rain]

If your scene is empty, it doesn't mean that the engine isn't doing anything. There's a lot going on in the background. An engine is a complex thing.

[blissful whale]

Oh, it was because I gave the script to the wrong object. I'll try to understand Vector3.Distance meanwhile

[swift falcon]

Or just

if(Vector3.Distance(this.position, player.position) > 3)

🤷‍♂️

[blissful whale]

alright

[plucky karma]

Vector3.Distance calculates the distance between two Vector3 points.
The code above is a simplify, yet, less expensive than calling Vector3.Distance due to the fact that it must use sqrt operation (costly)

[swift falcon]

Do this.transform.position though

Same thing for the player, don’t forget the transform part

[hexed pecan]

I dont know much about jobs, but most of those look like some idle stuff

[plucky karma]

Are you missing an enclosure?

[hexed pecan]

I wonder what is MyTimerCallback 🤔

Oh its a Threading thing too. The naming just confused me. Like an example method lol

[swift falcon]

@blissful whale and honestly calculating the distance each frame when you have tons of doors is pretty expensive, so I would personally just use a trigger which is cheaper in this case

[blissful whale]

I will be planning to continue this game's development and add more levels, probably you are right
