for a state machine, over the network

I want examples because my brain is not braining, I can't think of handling player inputs and a state machine over the network

thank you in advance for the help 🙂

since there are so many updates and stuff happening, having this script on each player would be chaotic...

I can't wrap my head around it

[marble kindle]

I'm hoping maybe someone can give me pointers as to what in the heck I'm doing wrong here. The enemy is supposed to approach the train when they touch the ground.

As it stands, the code I have is thus

" private void Movement()
{
Vector3 targetRotation;
targetRotation = new Vector3(player.transform.position.x - transform.position.x, 0f, player.transform.position.z - transform.position.z).normalized;
enemyRB.AddForce(Vector3.forward * speed, ForceMode.Impulse);
}"

when I place this inside my fixedUpdate it works as intended. Great.

But when I move it into an if block, it stops working entirely and the enemy just stands there.

effectively this makes it stop working

" private void FixedUpdate()
{
GroundCheck();

    if (onGround == true)
    {
        LookAt();
        walkState = true;
        Movement();
    }
    else
    { 
        walkState = false;
    }
}"

The groundcheck works. the bool clicks on. I must be making some minor mistake somewhere. Can anyone tell me what I am doing wrong?

[naive pawn]

!code

[rich adder]

if doesnt' work with if onGround being true, its probably not working reliably as you assume / should also test it without LookAt()

I tried removing the look function and also moving the groundcheck to normal Update. Still nada.

I also tried setting onGround to toggle on and off manually, so like, that's still not doing it. It'll look in the correct direction, but the addForce never seems to take.

I halfway wonder if it's because I'm using a wheel collider for the enemy to slide around on, but that should theoretically still work inside an if block.

[rich adder]

what do you mean the player has a wheel collider on it?

[marble kindle]

The skeleton. it has one so it can slide forward and back towards the player.

Other code functions in the IF block. Just not the addforce(Vector3.forward) bit.

[rich adder]

thats probably causing issue

[marble kindle]

Why does it work outside the if block but not inside it?

That's the thing I'm trying to figure out.

Because it functions 100% as intended outside the if statement.

I'm not actually influencing the wheel collider. I'm just adding force to the rigidbody.

[rich adder]

the conditions are not met, there is no other cause

if it only works outside if statement, its pretty straight forward

[marble kindle]

Yeah. I'm just... If it's "If onGround == true" and it doesn't work even if I manually toggle that on and off, the conditions are being met.

[rich adder]

where are you toggling it?

[marble kindle]

Which is the entire problem. It can't be my raycast to groundcheck not working.

In the editor. Also in code. I tried both ways.

[rich adder]

put log inside the code itself and double check

Debug.Log($"onGround ? {onGround}");
if (onGround){
            Movement();

[marble kindle]

Yeah. Debug.Log pops up just fine.

[rich adder]

yes but whats important is what is it printing before if statement

uncheck Collapse if needed

[marble kindle]

Collapse? Edit: Oh. Collapse. Got it.

It says it's registering as true.

Yet my movement still doesn't work inside an if block.

[rich adder]

send entire code as is now

Hi, I have a question regarding unity and supabase (or any db hosted services). Basically I need to make a game that makes use of a database, So i created a supabase account and created the db and setup the authetification system. Now to communicate with my service, what do i need to do exactly? Do i need to setup an api, download an sdk or dlls, etc. I am very new to all of this and any help would be greatly appreciated!
Basically what i want to do is retriever a plyer state, which would store player data and scene number

[rich adder]

You should only communicate with your database through a server using common methods like REST API

you should never have any information about your database like connection strings inside your unity Game or anything Local

[marble kindle]

https://paste.mod.gg/omtfxwhnipuw/0

Think I did this correctly. It's a little sloppy. First project and all.

Well, first in Unity anyways.

[bold panther]

ok and would you know where i could find documentation about th whole procedure? like how to make a script that would connect to supabase with the proper data, and use the api , and how to setup the api?

[rich adder]

there isn't exact documentation generally this is done with accumulated experience knowledge, Id say start with how to create simple WebApp / Rest with .NET core then you simply make the Get/Put requests through Unitys Webrequests

[marble kindle]

Oh darn it. It was working right. I had the mass on my npc set to a stupid number. Oh I'm so sorry for bothering you. Thank you for taking the time to deal with me not looking at everything in my project.

There's no need for a skeleton to weigh 1000kg.

[rich adder]

that mass is crazy high, also kinda threw me off that with same mass you said it was working without if or you changed mass after >?

[marble kindle]

Yeah. I'm thinking it only worked before because the NPC started spawned in the air and had no friction or resistance so could build momentum before it landed. I had it all messed up!

[rich adder]

https://dotnet.microsoft.com/en-us/apps/aspnet/apis
https://supabase.com/docs/reference/csharp/introduction
https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-web-api

[bold panther]

ye i read the documentation in second link but perhaps i am missing something but i dont find where to like create my own api

but thanks for the extra ressources

[rich adder]

the first link / third link for example you create Functions that you can call that do the operations in the second link

thats all the API is, common function that perform an operation

"I want to give player X , 100 credits"

call myappurl/giveCredits?100 with proper verified auth token and do the thing

[nocturne pond]

Hey everyone so im making a top down 2d game in unity and i want to make a simple setup where i can shoot an enemy, he takes damage eventually dies after 10 hits, and he also shoots projectiles to me and damages and can kill me so i have the shooting system for both the player and enemy setup but they arent dealing any damage to eachother for a reminder im a beginner and i have done most of my code with ai help and right now im stuck because even ai doesnt know what the problem is😭 heres a small video of what it looks like so far

[bold panther]

so if i get this right, in unity i will only use libraries for networking and io, and use the api, the supabase will do all the work related to the db and authetification right?

[rich adder]

in Unity youd only use WebRequest to make common calls like Get request, Post request etc.
the webapp is basically an app running on a server that listens for Auth, Put/Get requests that then handle the Supabase operation such as inserting database entry or modifying it

[bold panther]

alright now this makes way more sense omfg

istg all the videos i saw

were talking about installing an sdk

and adding the right dlls and all

even gpt was tweaking

[rich adder]

there might be an SDK available for supabase but probably third party..

[bold panther]

thanks a lot for clarifying thins man

[bold panther]

yep exactly on a github repo

which makes it even more a pain

[rich adder]

the point is, you never want to store directly information about your database in unity

anything that lives on the users PC can be decompiled

they would know your databse keys and insert their own data or worse, corrupt / overload it

[bold panther]

i mean wouldnt the anon key and the project url be safe to expose?

form what i read only the secret key needs to be kept private

[rich adder]

you should have control over it at all times, I would never store any keys locally if it has an SDK that can handle certain things with a public key then its different but you still need proper auth

its less likely that user could get keys if you have those stored on a server app

all they see if they decompile your local project is that you make Get requests etc.. pretty useless to them

[bold panther]

true true

well man thanks a lot for ur time fr

i rlly appreciate it

uve been more helpful than anything ive seen lol

[rich adder]

np. n goodluck.
Remember to start small, lock in the concepts and slowly go into a bigger scale

start with API with no Database and only stores in memory, then move into doing extenral database talks

[nocturne pond]

Hey nav sorry to bother you but you seem like you know how to programm well any chance you could help me with the problem i have?

[rich adder]

the video doesn't work

[nocturne pond]

oh

wait

one sec

lemme do a yt link

[rich adder]

jus make it mp4

[nocturne pond]

idk how

yt link is easier dw

[naive pawn]

use an mp4

[rich adder]

did you use OBS it has built in converter

[naive pawn]

you can't just google "mkv to mp4 online"?

[nocturne pond]

true

k lemme do that

[civic palm]

how do you define a unity input system input map in code?

if i wanted to reference it in start for example

[naive pawn]

you would construct it, i imagine

ok, do you want to define one, or do you want to declare a variable to reference one

[nocturne pond]

k here

[rich adder]

a you have a bunch of console message you seem to be ignoring.
also you have to show code

[naive pawn]

are your layers set up correctly

[nocturne pond]

normally yeah

[nocturne pond]

im not

[rich adder]

whats the usecase what do you mean define action map? you mean reference it ?

[nocturne pond]

wait im so sorry guys i have to go eat i can give all those infos in like 20 minutes ill be back im so sorry again

[naive pawn]

what do you mean "normally"

is it not set up correctly now?

[civic palm]

yea reference my b, in my script i want to disable or enable the action map when in OnEnable ans OnDisable, so i want to tell the script on start what the variable i made is tied to (the action map)

[rich adder]

did you generate a c# class for it or no

[civic palm]

i think it made a script for it yea

Called PlayerControlls

Player Controll Inputs

im not rly sure

[rich adder]

made a script and generated c# class from action map are two different things lol

[civic palm]

i am just wondering is there code to reference an action map

so i can disable/enable it

[swift crag]

There's no InputActionMapReference, annoyingly

I've thought about trying to make one myself

[civic palm]

even if my script that uses input system is disabled, it will continue doing inputs for it

[swift crag]

you can, of course, find an action map from an input action asset

[civic palm]

oh i see i see

so could i reference that and disable the map part of it?

[rich adder]

you could use InputActionAsset and find it there

I just generate a C# class from it so its easy / type safe

this way you can do
MyCustomActions myCustomActions
myCustomActions = new()
myCustomActions.Enable()

myCustomActions.Player.Shoot etc.

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.8/manual/ActionAssets.html#type-safe-c-api-generation

just dont name it anything unity has like common mistake is PlayerInput cause it collides with the component

[civic palm]

the script generated by the input asset has a bunch of errors on it

[rich adder]

like wat?

[civic palm]

not sure why it like dat

[rich adder]

are the errors also in unity console

[civic palm]

ya

lots of errors

[nocturne pond]

i think it is

[rich adder]

why do you have PlayerControllerInputAsset and PlayerController

[nocturne pond]

so which scripts do you want me to show? btw the enemy is a boss

[civic palm]

hold up

i figured it out

[rich adder]

probably the ones that relate to the shooting. / actions to do when projectile collides?

[civic palm]

i had a duplicate of the script in another folder

[rich adder]

thats probably why it errors

[civic palm]

or from another one of the input actions i had made in the past

whoops

@rich adder the script has no errors now, but i am not sure where to go from here

[rich adder]

You should be able to access it as regular object like I shown here
#💻┃code-beginner message

[nocturne pond]

okay here:

[nocturne pond]

i think a main problem i have is that my codes a mess?

[rich adder]

the big problem is you wrote none of this and let something write slop for you which you understand none of

[nocturne pond]

yeah ik i just dont know how to start

i can understand prob 50 percent of it

[rich adder]

you start with learning the basics , then work your knowledge up so you can actually put pieces together you can easily understand

[nocturne pond]

so im not skilled enough to make this game yet right?

[rich adder]

put it on pause and start simpler

[nocturne pond]

also i dont understand how is this code that bad like could you give me examples possibly?

[nocturne pond]

alright

[rich adder]

where you wrote all the code and know each line

[rich adder]

its mainly bad because you wrote none of it and don't undstand what its all doing so debugging will be more diffcult, also you need to check if the gameobjects have the tags that they require

lots of redundant / outdated functions too

[nocturne pond]

okay that makes since I did this because i do the same thing as all beginners i think i can make a big project but end up failing i just dk how to like actually learn and start cuz ive done like 5 of unity's tutorial games and i remember like none of it and i cant code a single thing basically

[nocturne pond]

mm okay makes since

[rich adder]

at least you are aware

thats a good step

[nocturne pond]

yeah

[nocturne pond]

haha

[rich adder]

if you start small, in no time you will get to bigger projects

if you start big right away, you will crash and burn quick

[nocturne pond]

yeah but the thing is idk how to start cuz like i said ive done like 5 tutorial games from unity and basically learnt nothing so idk what to do to start actually learning

like functions

[rich adder]

learn nothing because you most likely didnt practice enough what you just learned, especially on your own without the guidance of the tutorial

You cant / should not move on the next lesson if you didnt practice and can repeat what you learned on your own

[nocturne pond]

okay

[nocturne pond]

okay thats true

how did you start coding?

[rich adder]

I started with modding HalfLife with some C++ then realized the same thing (hit limits of low knowledge)

started small with unity and c# and built up knowledge

[velvet lantern]

hihi! hopefully simple to answer, but how would i reference the "source image" field of this component in c#? I'm relatively used to working with gameobjects but haven't done much with UI yet, and need to change the sprite of this section of the UI to display the player's health

every tutorial I find online seems to reference either an older version of unity, or uses a method i can't adapt ^^;

[nocturne pond]

yeah but like which tutorials or whatever did you use? should i try just looking at the functions that exist and try to like make a programm out of them?

[rich adder]

https://docs.unity3d.com/Packages/com.unity.ugui@2.0/api/UnityEngine.UI.Image.html
https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Sprite.html

[naive pawn]

the reverse, try to make something and figure out what you need to make that thing

[rich adder]

right. Like "How to move an object"

not. "how to make movement like zelda etc."

try to be more generic

[velvet lantern]

ah yeah that'd do it

thank you !

[nocturne pond]

okay

[rich adder]

also now they have decent lessons on https://learn.unity.com

when i started it barely existed

[nocturne pond]

okay so like id prob say like doing the thing where you do like tim.deltaTime * speed blablabla is that old code i saw from ai or is that relevant?

[nocturne pond]

and then like xvelocity and y velocity * speed blablabla

[rich adder]

once I understood what deltaTime is you more or less know when to use it

in a nutshell its used to give you consistent values between diff framerate speeds

if you did timer += 1 in update, your timer goes up faster on higher FPS
if you did timer += 1 * Time.deltaTime it increases the same speed no matter the fps
deltaTime is the time in seconds it took since the last frame processed

[nocturne pond]

yeah see thats the thing like with C# you cant think normally to move a player for example like you have to think mathematically like u cant just put Player.movement = if w key pressed move forward... right?

[naive pawn]

you don't have to think mathematically, no

[nocturne pond]

ohhh thats a rlly good way to explain it

[rich adder]

c# and unity api / gamedev concepts are kinda different

[nocturne pond]

why do i feel like thats the case then?

[naive pawn]

you have to think logically, and keep the cyclic nature of Update in mind

[nocturne pond]

oh okay

[rich adder]

c# itself is just a tool / language to accomplish something,
Unity gives you API (functions and whatnot) to maniupulate its engine

[nocturne pond]

mmm okay

[rich adder]

Update and such are Unity concepts not necessairly c# related

you learn them through the manual

[nocturne pond]

so API is kindof to link the coding and the gamengine to make the code work as functions right?

[rich adder]

its a common language you can use to communicate with the backend

[nocturne pond]

ohh thats interesting i thought that was part of C# basically

[rich adder]

in this case c# was chosen

its like a telephone number you can dial local to get connected to a bigger system

[nocturne pond]

okay

[rich adder]

the original engine is written in c++

[nocturne pond]

so if i want to start learning right now what tutorial or whatever should i do right now?

[nocturne pond]

oh then why doesnt it use c++?

[rich adder]

probably because c# is much much easier to pickup

[nocturne pond]

mm okay

[rich adder]

do a bit of traditional c# courses + unity specific ones on the https://learn.unity.com/pathways

learning traditional c# is important, objects, logic flow, types etc

some like https://learn.microsoft.com/en-us/shows/csharp-fundamentals-for-absolute-beginners/

it seems boring and basic, but pays dividends

[nocturne pond]

okay thank you ill save this

[nocturne pond]

yh thats the hard part

[rich adder]

thats the learning curve aspect, but its pretty low not steep

thats why you balance it with unity, so its a bit more fun

[nocturne pond]

rly like as soon as i know the basics i can just pretty easily go up from there u think?

[nocturne pond]

mm okay

[rich adder]

yes like anything else, a painter doesnt start with a mona lisa, you have to learn how and when to apply certain tools, brush type, color etc.

[nocturne pond]

yes very true

[rich adder]

seeing object move because you learned how to manipulate values is satisfying

[nocturne pond]

yeah for sure

alright well tysm you were an amazing help to me im looking forward to speak to you again if i need any more help

[gloomy loom]

could someone please help me 😭

[rich adder]

maybe..try asking a specific question

[gloomy loom]

alr

does ANYONE here know how to delete a unity package?

im new to unity

[naive pawn]

have you tried like, googling that

[gloomy loom]

yeah

[naive pawn]

it's a pretty general question, google will have plenty of answers, and it'll be faster and easier than asking and waiting tbh

package manager -> remove package

if it's locked, it can't be removed because some other package is using it

[gloomy loom]

ahhh...

ty

im tryna use photon, i messed it up lol

[rich adder]

you're doing multiplayer but don't know how package manager works, ouch

[gloomy loom]

:[

[nocturne pond]

hey so nav can you make like mods for games or like plugins for any game with C#?

[civic palm]

i am struggling to get the input action maps to actually disable when i have the script referenced in my code, I have the script referenced in my code (1st image) and then when the script is disabled/enabled it should turn the input maps on and off right? am i doing something wrong?

movement is my action map

[rich adder]

first I'd put logs to see if that part of the code is even running

[civic palm]

just tried it and when it was disabled it did put a log

idk why it wont disable my input map, it so confusing

i have an action that involves clicking but it still lets me do it even with script disabled

[rich adder]

is the clicking action in the Movement map ?

[civic palm]

yea

all other inputs also enabled not just click

[rich adder]

and where in the code are you using this map

[civic palm]

in a script called movement, i have a function for each action that gets the inputs and makes player move/jump/dash

that is also the script where i enable and disable the stuff, should i make it seperate perhaps?

[rich adder]

if you planning on disabling / enabling on demand you should track in one spot

[civic palm]

i do have two states that the player can be in (normal 2d controls a powerup that changes controls), so maybe i could put that in the script that deals with swapping states?

[rich adder]

You could always verify that the actionamp is enabled / disabled with a log as well

Debug.Log($"is movement enabled ? {PlayerControllerScript.Movement.enabled}");

verify its actually disabling it when you do / before using it

[civic palm]

it says false

thats so strange

i have to be overlooking something maybe

[rich adder]

probably. you should also show where you utilize these actions in code

make sure you're linking the correct map

[civic palm]

i found a dumb way to do it

i just disable the player input component

baboom

idk if thats a good way to do it tho

[rich adder]

you were using PlayerInput in the first place ?

[civic palm]

is that a bad idea to use the player input component?

[rich adder]

its not but you should not use both

you shouldn't be mixing them thats prob why you got odd results

[civic palm]

wait i am confused

[rich adder]

if you already have a generated class from the ActionMap, you don't need the PlayerInput component at all

PlayerInput is mainly used if you use Inspector to link Actions or/ using the SendMessages modes

[civic palm]

ok so wait, if i am using the player input component on my player object, should i not worry about using the script generated from the action asset

or should i get rid of player input component and change how my player controls work? i have been using that to get my controls, by adding events that are triggered by code

[rich adder]

like I said use one or the other, the whole point of a generated class is to skip using the inspector and you already have type safe properties like
Movement.Jump would show up in code

your IDE doesn't look configured peoperly ? are you even getting the intellisense suggestions

[civic palm]

yea im not sure, how can i set up the intellisense stuff correctly

[rich adder]

[royal monolith]

Hi, trying to make a track which is flat and goes around in 1 loop but this little junctions keeps happening. Could anyone help me? Thanks in advance.

[queen adder]

Put yourself in a wheel and roll until you being to see it go in a spiral.

[broken nest]

Has the image component changed? Why do I have to manually set my assets to 2d sprite?

[rich adder]

not a code question.
and they made it sprite- multiple for default sprites so dragging the root in a sprite field doesn't work, you need to change it back to single

[solar hill]

what

[royal monolith]

Wait what?

[queen adder]

It's sarcasm.

[solar hill]

this is a help channel

[royal monolith]

Oh 😂 yeah I am kinda fried been at this for some time 😂😂😂

[solar hill]

if you are going to comment on someones issue try to actually help

[red igloo]

So I finally have the slam ability setup but I have this issue where sometimes when using the normal slam its not going as fast as its suppose to so sometimes its fast sometimes its slow.

Script: https://paste.ofcode.org/Y9gVXhkp8w33f7tBS54pyh

[solar hill]

are you cancelling your vertical velocity before the slam happens?

if youre still moving up when you decide to slam it could counteract the downward force causing it to be slower

youre not i just checked

do that and see if the issue persists

[red igloo]

Yes in my playermovement script I got

{
    Vector3 v = rb.linearVelocity;

    v.y = 0f;
    rb.linearVelocity = v;

    rb.AddForce(doubleJump * Vector3.up, ForceMode.Impulse);
    doubleJumpUsed = true;
} ```

[solar hill]

isnt this just for your jump?

[red igloo]

Yes just for the jump just confused at this point.

[lethal meadow]

how do you do the highlight?

[red igloo]

asset store

[solar hill]

then it has nothing to do with your current issue

and you should try doing what i suggested

you also dont have to overcomplicate it like you did it in your jump script, im pretty sure you can just do

rb.linearVelocity = new Vector3(rb.linearVelocity.x, 0f, rb.linearVelocity.z);

add this to both of your slam methods.

also why are your slams 2 seperate functions at all?

[red igloo]

Just found it easier one is for when your high = stronger slam and the other is when your not high = weaker slam

[solar hill]

you should keep it as a single function and just parameterize it

[high anchor]

Is there a good tutorial going over the in-engine variables (object parameters and such) and going into detail on how to find and use them?

[wintry quarry]

That sounds extremely vague.

"in-engine variables (object parameters and such)" is way too vague to be meaningful

[high anchor]

It is extremely vague, yes. I'm kind of taking a shot in the dark.

Let me try to narrow it down...

[wintry quarry]

Can you explain what you're trying to do? Just learn to be comfortable programming in Unity?

Have you looked at !learn?

!learn

[radiant void]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[swift crag]

You have bad spline segments

[high anchor]

Yes. Problem is, I have no idea what I'm actually looking for and I don't really want to skim through 'over 750 hours' of stuff to figure it out.

So let me see if I can try and get an example of where I'm stuck...

[swift crag]

here's an example of this sort of thing in Blender

[wintry quarry]

You don't skim through all of it. Start with the junior programmer pathway to get familiar with the basics of scripting

[swift crag]

this happens because the two nearby spline points have very large weights

they both want to push the spline very hard

so it kinks up

[high anchor]

So, I know 'the basics of scripting'. I have an associate's degree in programming. (And then I never got a job because I live in the middle of nowhere and was unable to compete for remote work and am now about two years rusty, minus some playing around on CodeWars to keep a modicum of basic skill up)

My problem is, I don't know how to, say, get the variables that govern the size of a game object into a script so that I can then have it make another game object change in size proportionally whenever that first object's size is changed.

[solar hill]

the junior programmer pathway isnt just there to teach you coding, if youre new to unity you still stand to benefit from watching them

as they will teach you unity specific stuff* like this

[high anchor]

(It's arguable exactly how much that 'keeping up a modicum of basic skill' actually worked, but here we are)

[solar hill]

but other than that what you are actually looking for is the unity api

[swift crag]

you should check out the documentation – both the manual and the scripting API

[solar hill]

you also still need to learn to use the editor itself

[swift crag]

https://docs.unity3d.com/Manual/GameObjects.html

for example, this explains what GameObjects are and how they work – including Transforms

you can then consult the scripting API to learn about how to interact with these things https://docs.unity3d.com/ScriptReference/Transform.html

[wintry quarry]

"Size of a gameobject" is also pretty vague, but in general you're going to need to look up all these specific things whenever you need them until you get used to them. becasue there are literally thousands of components and variables. You can't just read them all and learn them. The best way to learn is to look them up as needed and you'll get familiar with the ones you use a lot

But "size of a gameobject" could mean anything from its scale, to the extents of its renderer bounds, to something custom in the context of a particular game

[swift crag]

yes, that needs to be clearly defined first (:

a game object does not have a "size"

[pastel cave]

I believe what they're asking is literally being able to attach a setter to the transform component

[wintry quarry]

sounds like you're mostly looking for Transform.localScale here

[pastel cave]

I've actually been vaguely curious about a tangentially related topic myself. Not nessicarily in response to any problem, but how extensible is Unity?
Being closed source and all. I've seen some interesting prospects of plugging into the physics engine, but nothing beyond that

[swift crag]

The "core" of Unity is closed-source C++

[high anchor]

Scale is what I was referring to. Please forgive me, I'm mildly stressed out by the fact that I'm having as much trouble as I am.

Thank you for the help so far. I at least feel like I have an idea of where to work from now.

[wintry quarry]

very extensible, depending on your definition of extensible

[swift crag]

Many of its features are implemented in packages, which are mostly C#

for example, UGUI (the Canvas-based UI system) is all in a package you can go look at and modify

[pastel cave]

I see

[swift crag]

The core stuff is a bunch of thin C# wrappers that call into native engine code

[pastel cave]

Mhm, I've gleamed as much

That's good to know, though

[boreal ingot]

guys i am trying to make multiplayer into my game and its really just messing it up. i decided to have copilot help me with this but i can t get a sync correctly andd everytime i get copilot to try and fix it i feel like it makes me code really bad. anyway thats something i have to manually fix laster going throught all the code to see what bs it did but now what i want is some help to sync it correctly so the game can work. i have been at this for 5 hours i really need help would appreciate a call

[solar hill]

theres no voice channels here, if you need help you should share what you did, what you are trying to do, any relevant code etc.

be as detailed as possible

you should also probably take this to #1390346492019212368

[boreal ingot]

i don t know what i should send. also maybe something is wrong in my unity side .

[teal viper]

Start a thread, share you scene setup, objects, components, then code involved in the multiplayer and syncing. Then screenshots or video of the issue and explanation of the steps you took to debug it.

[broken nest]

Hey, why can't I make a list of a struict?

[polar acorn]

Why not what's stopping you

[meager siren]

How would one use OnPointerEnter?

Cause im trying to add a visual upgrade system that pauses the game (Sets timescale to 0 after a level up). Ive done it but I can't seem to well. im using oncollision enter and the pointer handler thing for the script isnt working

hard to explain

for me atleast

[twin pivot]

What does OnPointerEnter require

[meager siren]

wdym?

[rough granite]

Unity's docs have no matches with OnPointerEnter are you certain it's a thing? (i swear i've heard the thing but like there are no docs for it), also i think they mean what is the interface it's from

[meager siren]

oH

I needa check that

[teal viper]

There is in the ui package docs.

[edgy tangle]

You need the IPointerEnterHandler interface

[meager siren]

how would I get it?

[edgy tangle]

You need to implement the interface. Similar to marking a class inheritance

[teal viper]

Make sure your class implements it. How did you even get to that code without knowing about the interface?

[meager siren]

it didnt tell me :p

[teal viper]

Who??

[meager siren]

internet

Or I just didnt well. Look hard enough ig

[rough granite]

is this a different doc then the scripting api?

[edgy tangle]

public class MySuperCoolClass : MonoBehaviour, IPointerEnterHandler

[meager siren]

I did that in the screenshot

[slender nymph]

now you need to correctly implement the method

[teal viper]

Yeah, packages have their own docs that are not indexed very well in Google. Try searching for unity ui package docs.

[meager siren]

it's just an error for me. And the method doesnt show up

[rough granite]

i did not know this, thought it was all in scripting api :/

[slender nymph]

wdym "the method doesn't show up"?

[teal viper]

Nope. That one mostly only includes the core api.

[edgy tangle]

This is normal. It means you need to implement the method

[meager siren]

So I just type it in myself?

[edgy tangle]

The error is telling you you have implemented the interface but have not implemented its requirements

[slender nymph]

it's not a member of the inherited class. just right click the interface name and use the quick actions to implement it

[meager siren]

Man I needa learn unitys particle system badly

[meager siren]

alright

OHH

I SEE WHAT YOU MEAN

Now imma hope this actually works :p

[rough granite]

interesting i found it but it seems deprecated no? the last version to have any documentation on it was 2023.2

[slender nymph]

it's in the UI package docs because it comes from the UI package

[teal viper]

It's 3.0. Check 2.0. It's the same version since 2019.2.

3.0 was probably a discarded experimental version.

[meager siren]

Now its just doing this

does it matter that scripts on an empty gameobject?

nvm

[slender nymph]

yes that matters. if this is a UI object it needs a graphic to work. if it is world space it needs a collider

[meager siren]

I figured out why I just dunno how to fix it without removing the crosshair

[meager siren]

it works I just need to remove the crosshair

[slender nymph]

make sure your crosshair is not a raycast target

[meager siren]

alright

that would make sense

there we go

thank you again boxfriend

[meager siren]

question, how long have you been programming for?

random unity encounter???

[cosmic dagger]

it's pointless to check if color is null because Color is a struct. the expression will always be true . . .

[meager siren]

my fault

[meager siren]

love your name btw

[cosmic dagger]

i used to change it more often, depending on the season, but it was RandomUnityXXX . . .

"XXX" was replaced with smth different, but this has stuck for a while . . .

[meager siren]

You love your dotpoints dontcha?

are they even dot points or am I crazy

[cosmic dagger]

it used to be ... but they gave me an upgrade to . . .

[meager siren]

😭

Now I wanna make my display name something like yours

[cosmic dagger]

you'll find smth that fits. give it time . . .

[sacred thorn]

Hey im new to game development and i just for the life of me figure out how to make a slide function for pistols and if anyone can help me out a bit heres the code of one version out of many of my attempts
using UnityEngine;

public class SlideRack : MonoBehaviour
{
private Vector3 startLocalPos; // husker startposition
private Quaternion startLocalRot; // husker rotation
public float slideLimit = 0.2f; // hvor langt ned X kan trækkes

private Transform grabTransform;

void Start()
{
    startLocalPos = transform.localPosition;
    startLocalRot = transform.localRotation;
}

void LateUpdate()
{
    // Lås rotation
    transform.localRotation = startLocalRot;

    // Lås Y/Z og kun bevæg X
    Vector3 pos = transform.localPosition;
    pos.y = startLocalPos.y;
    pos.z = startLocalPos.z;

    if (grabTransform != null)
    {
        // Håndens position i parent-local-space
        Vector3 handLocal = transform.parent.InverseTransformPoint(grabTransform.position);

        // Kun X, clamp mellem start og start - slideLimit
        pos.x = Mathf.Clamp(handLocal.x, startLocalPos.x - slideLimit, startLocalPos.x);
    }

    transform.localPosition = pos;
}

// Kald dette når hånden griber objektet
public void Grab(Transform hand)
{
    grabTransform = hand;
}

// Kald dette når hånden slipper objektet
public void Release()
{
    grabTransform = null;
}

}

[meager siren]

InverseTransformPoint?

whats that?

[sacred thorn]

it tells you where the point is in relation to this object.

[meager siren]

huh

that would be pretty useful im suggesting?

[sacred thorn]

basically it translate world space x,y and z too local space of an object

[meager siren]

Yeah this just tells me that I needa learn more stuff

[hushed pagoda]

is there anything wrong with my code it didnt work when i press d

[meager siren]

oh

we dont use that anymore. I think you can enable the use of it again

but we use

hold on

this stuff now

and this

But I am sure you can definintly re enable the old one

im not sure though

[hushed pagoda]

what to do then?

[slender nymph]

!input

[radiant void]

How to Set Input

To set Active Input Handling, go to:
Project Settings > Player > Active Input Handling

• Input Manager (Old): Use the original Input settings.
• Input System Package (New): Uses the new input system package.
• Both: Use both systems.

[meager siren]

that

I knew you could enable it somewhere

[hushed pagoda]

ty ill ty

[hushed pagoda]

where is player setting

unity hub or unity

[meager siren]

unity

at the bottom where its highlighted (somewhat)

[hushed pagoda]

what to do now

[meager siren]

hold on I was doing something

[hushed pagoda]

ok

[meager siren]

In othersettings change the active input handling

to the old one or both

[hushed pagoda]

i apply both so i can use both old and new type?

[meager siren]

if you want

then click apply at the bottom

dont forget that. Idek if it reminds you

[hushed pagoda]

it restarted when i did

ty for tell i am struck there for 3 days

if u dont mind can u tell differ b/w = and ==

[meager siren]

= is used to assign something

==

is checking if the variable is equal to whats on the right side

[hushed pagoda]

if == false what is the point of writing it down

[meager siren]

you can use it for other things like

if (integer == 1)
{
Do this
}

For bool variables you can just do
if (boolVariable) - Checks if true

if (!boolVariable) - Checks if false

[hushed pagoda]

ok one more thing where can i learn code

[meager siren]

oh

Well.

Idrk?

So its either you learn it from Unity Learn

which is useful

watch youtube videos, look at other peoples codes and searching up what they used and how they used it

its a bit. Weird if you dont have a school program for it

I do, they just dont teach C# :p

or an online course.

Like Code4Fun

[meager siren]

clearly lied here by accident 😭

[hushed pagoda]

ill try those sources ty

[rain solar]

when generating terrain with fractal noise how do i interpolate between noise samples? when i do linear interp the terrain looks low quality cause its just a bunch of squares and i cant use bicubic because it creates wavy terrain

[dark root]

using UnityEngine;

public class paddlecontroller : MonoBehaviour
{
public Rigidbody2D padrb;
public float speed;
private float paddleInput = Input.GetAxis("Vertical");

void Start()
{
    
}
void Update()
{

    padrb.linearVelocityY = paddleInput * speed * Time.deltaTime;
   
}

}

Why doesn't this make my paddle move

I have no idea what I'm doing

[chrome tide]

you need to continuously read the input. in update, assign the paddleInput to Input.GetAxis("Vertical");.

[night raptor]

Also, I don't think you want to multiply the speed by deltaTime here. Often you want but in this case linearVelocity is already velocity in units/second and unity makes sure the object actually moves at that fixed speed regardless of the framerate. Multiplying by deltaTime here would do the opposite of what you want, it will make the object move at different speeds with different framerates

[dark root]

Thank you it works

[final sluice]

I made an Enemy script moving by following a path , after reaching each "Waypoint" , it will check if the relative distance between the enemy and the waypoint is 0 , if it is 0 and it isn't the last waypoint, it will keep moving.

It has been working super fine until now , for some reason the relative distance appeared that number whenever the Enemy reached SECOND waypoint. It's not even the first . I can't find a way to bybass it , I don't even understand what it is.

I use a spawner to spawn waves of enemies , which have been working fine until this happens . It also should be noted that if I drop a prefab of the enemy into the scene, its moving code work just fine. So I think it's a problem with the spawner, which I don't understand what it is since it's only job is to spawn stuff.

Pls help, im dying

This is the moving script

Is this a bug, or did I do something stupid

Please help aaaaaaaa

[midnight plover]

That number is close to 0. You should never use == with float numbers, as they are never 100% precise. You can use something like mathf.approximately

[final sluice]

THANK YOU, IT WORKS

[stone oar]

hey so I was trying to edit the bloom.active variable using a script to enable/disable bloom at runtime. toggling it via inspector in editor mode works fine, but as soon as i start play mode - even using inspector doesn't do anything.

i use volume.profile.TryGet<Bloom>(out bloom); in Start() method to get the bloom value out from the Volume volume component and then edit it via bloom.active = true/false. I can see the changes to the variable in inspector (aka the box ticks off) but it has no effect on the game itself.

BUT when I remove the TryGet line entirely - suddenly I can edit the bloom and all other post-processing effects in inspector in play mode. what's going on? all tutorials use this structure and i have no idea why i it doesn't work for me specifically

[midnight plover]

Show your entire script best case

[stone oar]

public Volume volume;
private Bloom bloom;

void Start()
    {
        volume.profile = Instantiate(volume.sharedProfile);
        volume.profile.TryGet<Bloom>(out bloom);
    }

void BloomSetting()
{
  bloom.active = false;
}```

its really nothing special

bloom starts turned ON and i just try to turn it OFF

i also tried the version without volume.profile = Instantiate(volume.sharedProfile) to no avial

it looked like this:

public Volume volume;
private Bloom bloom;

void Start()
    {
        volume.profile.TryGet<Bloom>(out bloom);
    }

void BloomSetting()
{
  bloom.active = false;
}```

[midnight plover]

and you dont get any errors?

[stone oar]

no

hm actually i do

NullReferenceException: Object reference not set to an instance of an object

[midnight plover]

well, your bloom is not working getting returned but you access it I guess

[stone oar]

right around the bloom.active = false;

so ig it just doesnt know what bloom i use

[midnight plover]

you can use the tryget inside an if statement to check, if the out is actually delivered

the bloom should be the one in your volume profile

[stone oar]

Bloom is out! Bloom(Clone) (UnityEngine.Rendering.Universal.Bloom)
UnityEngine.Debug:Log (object)

the bloom IS getting disabled but it has no effect on the game

bloom is still active

if i remove the TryGet then i can change the bloom in inspector just fine

but with TryGet - i cant even do that

[stone oar]

i also fixed this error, so it has nothing to do with it

[midnight plover]

Then I guess the error might be, that your bloom is not the correct one. Its targeting not the instantiated profile

which script are you using now. The instantiated or the simple one?

[midnight plover]

also curious, you said, when you remove the tryget entirely. But are you still assigning a new profile to the volume in the line above?

[stone oar]

i dont understand what you're asking

[stone oar]

but it changes in the inspector?

[stone oar]

right here. when i remove tryget i can change it in play mode just fine

manually in inspector not through code

[midnight plover]

And the line volume.profile = Instantiat eis still present?

[stone oar]

i tested with and without

same result

[midnight plover]

When is BloomSetting() called?

[balmy vortex]

hi can you use gameObject.activeSelf to check if scripts on game objects are active too? or is it only for the actual game object itself?

[midnight plover]

If the gameobject is not active, scripts arent either (in terms of the unity game loop)

[stone oar]

when i press a button

[midnight plover]

what happens if you try inside the method

if(volume.profile.TryGet(out bloomComp))
  bloomComp.enabled = !bloomComp.enabled;
else
  Debug.Log("No bloom");

Not tested the code, if there are any typos 😄

[stone oar]

nope

does not work

also its .active not .enabled 😅

[ivory bobcat]

Active should be referring to a game object rather than a component. Bloom would be a component and use enable?

[stone oar]

well ill be damned but intellisense says otherwise

'Bloom' does not contain a definition for 'enabled' and no accessible extension method 'enabled' accepting a first argument of type 'Bloom' could be found (are you missing a using directive or an assembly reference?)CS1061

[ivory bobcat]

Guess it might be active for the specific volume component
https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@8.0/api/UnityEngine.Rendering.VolumeComponent.html

[polar acorn]

It's not a component, more like a component of a component. The actual component to enable is the Volume, but the Volume Profiles are their own individual thing that doesn't have any conventions to follow

[harsh tartan]

Hey im missing something, im following https://learn.unity.com/pathway/junior-programmer/unit/basic-gameplay/tutorial/lesson-2-1-player-positioning?version=6.0 and im at step 7, but it doesnt work anymore?

using Unity.Mathematics;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float horizontalInput;
    public float speed = 10.0f;

    public float xRange = 25.0f;


    public GameObject projectilePrefab;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (transform.position.x < -xRange)
        {
            transform.position = new Vector3(-xRange ,transform.position.y, transform.position.z);
        }


        if (transform.position.x > xRange)
        {
            transform.position = new Vector3(xRange, transform.position.y, transform.position.z);
        }




        horizontalInput = Input.GetAxis("Horizontal");
        transform.Translate(Vector3.right * horizontalInput * Time.deltaTime * speed);

        if (Input.GetKeyDown(KeyCode.Space))
        {
            Instantiate(projectilePrefab, transform.position, projectilePrefab.transform.rotation);
        }
    }
}
``` its trying to move  but keeps getting stuck at 0 0 0, and when trying to move the max position is gonna be -0.1
what did I do wrong?

[rich adder]

what did you set xRange in inspector as ?

try higher number

[harsh tartan]

at the player its at 10 but will try 40

[rich adder]

so you put it to 10 and its not moving at all ?

[harsh tartan]

now it works but now the border isnt working as I can go futher t hen 25.

And why does it work on 40 and not on 10?

[harsh tartan]

no its trying to move but when I dont press a button anymore it still on 0.0.0

[keen dew]

xRange is the border... if you set it to 40 then you can go up to 40

The number 25 in the code is the default. The value you put in the inspector is what it uses

[harsh tartan]

check thanks

[rancid tinsel]

is it possible to do something like GetComponent<(Image || CustomImage)>().value as long as both of them have the value field?

[naive pawn]

no, C# doesn't have union types in that way.

the type system is nominal, not structural

they'd need a common parent that has that field

[rancid tinsel]

I see, thank you!

[crude jungle]

Hey guys, I'm trying to apply the new Input System to some old navmesh tutorials. I've been through a lot of the documentation regarding the new Input system, I've checked previous posts on reddit and the Unity site and even searched for an answer in the Discord chat here. I saw someone using these .performed/.started/.canceled methods with their input controller, but mine don't seem to have a definition for it.

I've messed around with the input actions editor a bit to see if I could find anywhere that these methods were mentioned, which didn't work. In the example given, they also didn't provide any other context other than "this will work", so I don't really have any other key information to google at this point.

Is anyone able to shed some light on these by any chance? Cheers, tried to provide as much context as possible!

[rich adder]

You need to generate a C# class from the asset to be able to see the type-safe names on the right
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.8/manual/ActionAssets.html#type-safe-c-api-generation

[steel sapphire]

hi guys, have a very generic question
how can i make track for bike racing type game. if possible please share some resource, i couldn't find proper resources

[rich adder]

in what sense? mesh ? checkpoints?
what exactly are you talking about, this is a coding question?

You can use common methods like Spline tools, unity has one built in or get an asset purposefully built for roads

[steel sapphire]

in sense of large map.
i am making road rash type game, where map can large and will have many obstacles in between. like tyres, pedestrian, cars, baricade, animals, carts etc etc.

do i have to manually place all of these objects in the map?

[crude jungle]

Yikes, there goes about 1.5 hours I'll never get back when the answer was right there 😄 Thanks a lot! I hadn't added a Player Input component😅

[steel sapphire]

also thinking about, how the unity will render such a large map? does unity automatically takes care of optimization?

[rich adder]

Player Input component doesn't make it look like the screenshot on the right you sent. Just to be clear its a separate use than fully "in-code"
it uses inspector

[rich adder]

depends, some games will want this to be consistent and manually built
some games will generate them with randomness or some randomness but still predictable

You have to code these in, and there is minimal optimizations for objects not in view but thats about it, the rest must be optimized by you

road redemption is made in Unity so its totally doable

thats the closest I've seen to a road rash clone

[crude jungle]

You were correct, it was actually that I had missed the layer reference entirely in one of the places, thanks again!

[steel sapphire]

cool, how does this sound? will make the track, trees and other static object will places on map.
dynamic objects like cars, pedestrian will spawn based on certain distance from bike and destroy accordingly

correct me if you can think of a better idea

[rich adder]

sure, if you want to make it a bit more "complex"
Unity has splines tool like I mentioned, you can actually get the points on this spline so you could technically create incoming traffic, obstacles etc. on the fly

its usually the "middle" part so you can kinda figure in the width of each lane / road itself to get more accurate / consistent result

[steel sapphire]

cool thanks,

[rich adder]

basic ointro + sample unity includes for roads
https://youtu.be/FbSvEieELXo

more complex code/parts like figuring points on the road etc.

[broken nest]

Hello, I'm trying to build a tree, how can I do that? I was trying to make a recursive struct but that doesn't work

How does a gameobject can contain another gameobject as a field for instance

[frosty hound]

You can use whatever component is on that other GameObject as the type, or just use GameObject

[broken nest]

{
    Node node;
}

public struct NodeStruct
{
    NodeStruct node;
}```
Why does the first one work but not the second one?

[rich adder]

because structs are value types

it has no idea what size it needs to store it, reference types you're storing a pointer and they generally have a set size

computer: How big is NodeStruct?

answer: It needs the size of node,
But node is another NodeStruct
which contains another NodeStruct
which contains another NodeStruct

… forever, so needs infinite size

[broken nest]

Ok thanks a lot that makes sense

[swift crag]

To understand recursion, you must first understand recursion 😉

[charred spoke]

Oh I have a meme for this but can’t post it here

[frail hawk]

thank god there are loops

[balmy vortex]

hi is 1f from Time.deltaTime actually equal to 1 real world second?

cuz it feels way slower for some reason

[charred spoke]

Yolo

[charred spoke]

It should pretty much be real close

[rich adder]

its in seconds yes but you probably take into account discrepancies, you're still at mercy of speed inside the engine

[slender nymph]

It'll be scaled by the timescale too, but otherwise yes if timescale is 1 then adding deltaTime to something until it reaches 1 will be approximately 1 second (with some very slight variance based on framerate)

[charred spoke]

And electro gremlins

[balmy vortex]

[swift crag]

notably, if the game hitches for long enough, Time.deltaTime is clamped

the default limit is 1/3 of a second

that's probably not causing issues for you, though

[night raptor]

I thought that 1/3 second cap only applied to physics but that seems to similarly apply to max value for deltaTime. Makes some sense, but the tooltip and documentation weirdly enough only talk about physics there. One of those poorly documented features

[swift crag]

the actual docs are good https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Time-maximumDeltaTime.html

[night raptor]

Oh, I only checked the Time settings one from the manual side. I honestly didn't even know of that value, of course it has to be named differently too MaximumAllowedTimestep = MaximumDeltaTime. https://docs.unity3d.com/6000.3/Documentation/Manual/class-TimeManager.html

No links or mentions of the Scripting API equivalent

[civic palm]

im having a really annoying issue with my 2D platformer, im trying to get a drilling mechanic working correctly. Basically when my character dashes it makes a hitbox that when coming into contact with surfaces on a certain layer, you enter a drill mode that toggles another hitbox that waits for OntriggerExit2D to detect if that collider has exited. Randomly my drill mode instantly swaps me back to my normal 2D platformer controls when entering a surface and i have been trying to find the solution for ages

if any coding genuises would be okay with potentially getting into a voice call and i could screenshare id be okay with that, i feel it would be hard to get help with just images

[naive pawn]

we don't do vc's here, it would negate the benefits of having a community server to begin with

you can share screen recordings to show your issue if needed

[civic palm]

oh yea sure

i shouldve done that xD

[naive pawn]

i won't be free in a few mins, so just some general tips - play around with the mechanic a lot in various scenarios, different terrain, different angles if that's a factor, etc - try to find what the common denominator is, to then reliably reproduce the issue
from there, debug to see why the issue is occuring, possibly drawing debug or gizmo stuff to make sure stuff is lining up as it should

[swift crag]

Log the collider that's being exited in the OnTriggerExit2D method

Maybe you're exiting a collider that you didn't expect to be there

The bug could depend on how many frames you get between each physics update (by defualt, physics runs 50 times per second)

cool website

here is my code

[swift crag]

I see that you set swappingStates to true until the next fixed update. You aren't currently doing anything with that variable

my first suspicion is that the drill and dash colliders don't quite match

i noticed that you instantly exited drill mode while moving upwards

If you want to check if every element matches, you can either:

• iterate over them and compare each element
• use LINQ

nooo the question vanished

int[] foo = new int[] { 1, 2, 3 };

if (foo.SequenceEqual(new int[] { 4, 5, 6 }))
{
    
}

here's an example of using LINQ; it provides the SequenceEqual method

comparing for exact equality wouldn't be useful, since it'd just tell you if they were the same array

(i think, at least; i haven't really thought about the array equality operator before...)

also, the reason you got an error was that {1, 2, 3, 4, 5} isn't an array: it's syntax used when constructing an array

but it's not valid on its own

Newer versions of C# do have array literals, like this:

int[] foo = [1, 2, 3];

but not the version that Unity uses

[civic palm]

can u ellaborate on dis?

also does ontriggerexit tend to trigger twice perhaps?

[swift crag]

no, it only runs once each time a pair of colliders stop overlapping

[swift crag]

i'm wondering if the drill collider is briefly exiting the ground as you enter drill mode

[civic palm]

okay wait i just found something out

i can send clip

i realized that the drill always fails when the exit collider is positioned at the direction of the surface you drill into

at the start of the game the drillcollider is in the center of the player but after one time it always is where it last was upon exciting a drill mode

could that be important?

the green circle on the right side if the collidr

ok im testing it a bunch and that is for sure the issue or one of them

i am confudsed why it causes issues

is it because first frame is outside of wall? before hitbox is positioned to front

[civic palm]

this is gonna drive me craaaazy

[civic palm]

i think stuff breaks when the collider for drill and movement are overlapping upon entering drill state

but i dont know what to do to fix it, its just one gets enabled and one disabled simple as

[stone oar]

i feel youuur paaain

the wonders of programming :]

[swift crag]

is it possible that there's more than one collider causing trigger-exits for the DrillCollider?

annoyingly, trigger messages don't tell you what your collider was

only the other collider

[thin lotus]

how can I use the variable float speed = 0.1f; for the X value in transform.position += new Vector3(0.1f, 0, 0);?

[swift crag]

I'm not sure how this works in 2D physics. In 3D physics, if an object has a Rigidbody, it receives trigger messages caused by child colliders

[swift crag]

just plug it in!

the Vector3 constructor takes 3 float values

those can be literals (0.1f) or variables (speed)

[thin lotus]

but it gives me the error "Assets\Movement.cs(4,7): error CS0116: A namespace cannot directly contain members such as fields or methods"

line 4 defines the variable

[civic palm]

it shouldnt be since its only on a script that is on a child object of the player object

[polar acorn]

What does line 4 look like

[thin lotus]

float speed = 0.1f;

[polar acorn]

Did you actually put it inside the class

[thin lotus]

oh wait im dumb

oh

[swift crag]

fields are declared inside of a class, yes

[thin lotus]

thats a really dumb mistake i knew that

lol

[slow blaze]

I'm trying to make a type of node for mining which have a class that essentialy boils down to

class Node{
string nodeName;
int extractionValue;
int extractionSpeed;
}```
now this class is called in anothere monoBehaviour Object to make an instance of it

```C#
class MiningNode : Monobehaviour{
Node node;
//rest of code
}```
I want to manually set the nodes in the world, how can I manually give each object of the MiningNode prefab have different values in the node objeect through the editor?
would scriptableObjects be a better fit for this?

[civic palm]

im trying and trying and there is a slight change i might have found the issue, its the drill collider that is causing issues somehow but i dont know how

[eternal needle]

scriptable objects would help if you were reusing the same node across different mining nodes for sure. it'd be better organized as well
otherwise you just assign the values of node in the inspector as normal, make everything here serializable

[swift crag]

yeah – use a ScriptableObject if different prefabs can meaningfully refer to the same set of data

[slow blaze]

it'd be the same "node" class but the object itself (like the mesh, the view, animations, along with values) are going to be different

[swift crag]

in this case, I feel like each prefab is going to have a completely unrelated set of mining data

[slow blaze]

yeah they have different values but use the same class

but if there's like 3 iron nodes they would all use the same everything

[eternal needle]

so 3 iron nodes with different visuals, but the same node values right?
then for sure make that node class a scriptable object

oh i think i misread

[slow blaze]

the 3 iron nodes would have the same visuals and same nodes, they are the same

but 3 nodes say iron, gold, diamond, would all hold different values

[eternal needle]

it doesnt sound like you'd really gain or lose anything here making it a scriptable object regardless

even if there's a direct 1 to 1 relationship between prefab and instance of this node SO. I like making things like this an SO just cause it's cleaner to see in github tbh

[slow blaze]

I see
thanks for the insight

[pastel cave]

I am finding Unity's rules for physics increasingly nonsensical.
A Collider2D.Cast can't collide with things that don't have a RigidBody2D component. This is somewhat sensical.
But if the GameObject that HAS the collider has a RigidBody2D component, now suddenly it CAN collide with things that don't have a RigidBody2D component?

What is the logical throughline here I am missing

[polar acorn]

Rigidbody is the component that actually calls the physics engine. If there's no Rigidbody involved no one has access to the physics engine for collision detection.

Whenever any sort of collision happens, each object has a reference to the other, so either one can have the Rigidbody on it

The physics engine knows about all of its rigidbodies, and can basically ask "okay any of my rbs getting hit by something? No? Any of em doing the hitting? Ah, okay cool"

[pastel cave]

okay... Well this sort of proves a problem for me, because I'm trying to create Pong, and there's not a RigidBody2D mode that give me enough control to accurately recreate Pong

so I simply made a Ball that doesn't use RigidBody2D

[polar acorn]

Then you're going to need to do your collision detection without the physics engine using primitive shape casts

Or use a kinematic Rigidbody that you have full control over

[pastel cave]

the ball works fine, but then I went to add triggers, realized that they can't detect the ball and said "ah fuck it well surely just having an inert one wouldn't affect any existing bahviour, right? Maybe?" And then it did

[swift crag]

A Collider2D.Cast can't collide with things that don't have a RigidBody2D component.

Are you sure it's not the other way around? The documentation suggests that the object with the Collider2D also needs a Rigidbody2D to be attached to it

[pastel cave]

nope doesn't need one
or I've been hallucinating that my project works this entire time lmao

[pastel cave]

Kinematic provided me with unsatisfactory results. It penetrates other kinematics and statics, which wouldn't be AS big a deal if it didn't also collide with things behind the things it penetrates

it also can't be made to move programmatically

[polar acorn]

That's literally what it's for

A kinematic rigidbody is unaffected by forces and only moves when you explicitly tell it to in code

[pastel cave]

it's unaffected by forces, yes. But it seems to move exactly once every FixedUpdate and there isn't a method to force it to move

at least that I found

I could be wrong. My research wasn't during the hours of the day when one is completely clearminded

wait, no, I think there was a slide method

[polar acorn]

Well, yes. Every physics object moves once every FixedUpdate.

[pastel cave]

but a slide isn't what I need

[grand snow]

If unhappy with the physics time step increase it

[polar acorn]

And you "force" it to move by calling MovePosition

[pastel cave]

Oh?
How's that work

[grand snow]

📖 read da docs

[pastel cave]

it collides with things between where it currently is and the target of the MovePosition?

[polar acorn]

That's literally the way you're supposed to move a kinematic rigidbody

If you did anything but that, then you weren't actually using a Kinematic rigidbody

[pastel cave]

yes it seems to do exactly that

I see... What a strangely named method

let me double check that this is usable for me

Mmm. Is GetContacts only for overlaps or is it anything that the MovePosition Collided with last fixed update?

since it seems to still penetrate statics

but I might be able to give this another shot

assuming collisions are ordered sensibly...

[pliant dome]

I moved a gameobject with a box collider into a parent and the animation for the collider is broken. Is there a way to tell unity where it is or do I have to redo the keyframes all over again?

[grand snow]

You can correct the names in the animation window. Select a yellow one and press F2
Then correct the "Gameobject path"

[pliant dome]

Oh nice thank you

[civic palm]

@swift crag i fixed it!!!

took SO LONG

mostly fixed

still a bit buggy but its not deadass random

The main issue was the usage of ontriggerenter/exit2D

when the collider is teleported (so basically every fixedupdate for the drill collider) it will trigger the enter/exit

i also abandoned using tags to detect in/out and switched to using fixed update for both colliders and detecting a layer on a child object of the ground instead

ok its not fully fixed but it works because it starts drill -> cancles -> starts again so it works in a goofy way

will def have to solve that

[fallen mural]

can someone check the scripts ive written for my enemy? this is my first project so im not rlly sure if this is the correct way to do stuff since I have 5 scripts and 5 children for a simple enemy that just patrols, follows the player in a straight line if in sight and attacks if close enough
idk if should send them here since theyre long and theres 5 of them

this is 2d btw

[prime goblet]

if you send them then someone might help

[fallen mural]

alr i js wasnt sure if i should send it here since its a lot

this is what my hierarchy looks like

i feel like what ive done is a rlly suboptimal way to do it and i dont want to develop bad practices for future projects

[wintry quarry]

At the very least EnemyTopFlip and EnemyBottomFlip don't need to be separate scripts

they do almost entirely the same thing

[fallen mural]

i tried combining them but then i got problems where it would just break because one should only activate on trigger enters and one should only on exits, but if i combine them they both happen

but maybe i was js doing it wrong

[drifting cosmos]

am i correct about this If i use Physics2d.Raycast the raycast wont be scene isolated it will raycast through all scenes but if i save a reference to the scene and call it isolatedscene then do isolatedscene.Raycast then will it be scene isolated?

[rich adder]

for that you need to grab the PhysicsScene not the regular Scene

[drifting cosmos]

so just do something like this ? Scene currentScene = gameObject.scene; and isolatedscene = currentScene.GetPhysicsScene(); will it work with my physics simulator object thats in my scene that has this script on it ```public class PhysicsSimulator2D : MonoBehaviour
{
private PhysicsScene2D _physicsScene2D;

private void Start()
{
    Scene currentScene = gameObject.scene;
    _physicsScene2D = currentScene.GetPhysicsScene2D();
    Debug.Log($"PhysicsSimulator2D started in scene {currentScene.name}");
}

private void FixedUpdate()
{
    if (_physicsScene2D.IsValid())
    {
        _physicsScene2D.Simulate(Time.fixedDeltaTime);
    }
}

}```

[rich adder]

did you try it ? should work unless maybe you have to switch sim mode to script instead

https://learn.unity.com/tutorial/multi-scene-physics
https://docs.unity3d.com/6000.3/Documentation/Manual/physics-multi-scene.html

[drifting cosmos]

ill look into script mode thanks

ya still fuzzy on that but maybe for additional scene you might not even need to worry about that..

I think that setting only affects default scene?

[mint imp]

Idk if this is "beginner" exactly but i had a query for you wizards.
What would be an effective way to make swappable abilitys

RIght now im running code through scriptable objects that i can drag and drop into my "ability slot" for whatever ability i want to be using.
but my abilities are more complicated then i hoped.

What is the standard approach
Abstract class for ability that every ability devives from? then i just drag and drop the ability component into my object, and remove the old ability?

Im not sure

[naive pawn]

that doesn't sound super great for doing at runtime

keep in mind your SOs can also have methods

[timber tide]

Give requirements

They don't need to derive from a base, but you do need some sort of abstract method that they all share at least.

[golden notch]

if only unity had code backups. i went and made a window manager and it crashes the game and editor with no visible errors when i click the chat 🤦‍♂️

[slender nymph]

that's what version control is for.
but also, if i had to guess you probably have an infinite loop or infinite recursion somewhere

[golden notch]

yeah i did an if statement and it fixed the crash, but it's still not working properly

[slender nymph]

if you want help then you'll need to be more specific than "not working properly" and you'll have to provide relevant context

I want to have a parallax effect when i build this game on my device, but i dont see anything hapenning when i build it and run it on my android tablet.

Does anyone know what im doing wrong?

[midnight plover]

Do you see the effect in editor?

[limpid thistle]

No, my laptop doesn’t have a gyroscope

[livid anchor]

Not really a code question but does anyone know why the animation I made with the animation tool doesn't work on my tmp text ?

[midnight plover]

You can easily create a var in your inspector to fake it and be sure, that your script is correct. if its working that way, log the gyro somewhere in UI and see, if it actually gives you correct information back

[midnight plover]

why not ask in #🏃┃animation than, instead of asking the wrong channel on purpose 😄

[livid anchor]

Because i didn't see the channel !

[limpid thistle]

yeah doing that now, but building takes a while

[limpid thistle]

it says my gyro is disabled, but i clearly enable it in start and i am not touching the gyro in any other script

[livid anchor]

How do I force start an animation on a specific gameobject ? What do I need ? The animator controller ?

[twin pivot]

[livid anchor]

No I mean in code

[chrome tide]

well, you can change an animator's property via code - e.g. animator.SetBool()

the object will need an animator controller.

[livid anchor]

I think i'll need to work more on animations....

[midnight plover]

first off, are you sure your device has a actual gyro (yeh, weird question but I have been in the situation to have phoens without it). Second, are you using the old input setting (hence your Input.gyro), or the new one in your player settings? or both probably?

[limpid thistle]

Nope just using old input system, I also double checked the tablet I’m running should have a gyro, but could not find it anywhere in the settings. I have the galaxy tab A9+

[midnight plover]

You should check, if the gyroscope is allowed in your settings on the tablet too

Also you could install a third party app for testing sensors just to be sure, applications can read from your device

[limpid thistle]

ill try that, couldnt find anything about sensors or gyroscopes in the tablets settings

[midnight plover]

It probably has none and is using accelormeter or something to fake it

[limpid thistle]

gyroscope works, downloaded a test app and confirmed it

[limpid thistle]

im not sure why it disables the gyroscope because i set it to enabled in start

api does this Input.gyro.enabled = true;
instead of this gyro.enabled = true;

[midnight plover]

not sure what you mean. Input.gyro.enabled = true; is the correct one.

[true flame]

Right so i am just testing out a piece of code. So when the player collides with the enemy, it should show a message in the log. But it isn't working. Any ideas or suggestions?

[limpid thistle]

neither work, both options and they still start on false

[naive pawn]

add a log outside the conditional to see if you're getting any message at all

if not, go through this https://unity.huh.how/physics-messages/trigger-matrix-3d

[harsh tartan]

https://learn.unity.com/pathway/junior-programmer/unit/user-interface?version=6.0 is this still the best way to make menus? (like settings, new game, load game, pause button etc etc?)

[keen dew]

It's feasible and up to date. As with many other things there is no "best"

[harsh tartan]

so games make menus like that? when pressing ESC button, on the start with the screen, and no there isnt a "best" but there can be things that are better then that user-interface method

[keen dew]

Why would the official tutorial teach something that isn't usable

Instead of stressing about what way is better than another just start with something

[tight fossil]

im using RotateAround...Vector3.back for the left one which works fine, but the right one is using V3.forward (because using V3.back would just make it go in the same direction as the left one) which i assume would work if I could set it's starting point further along the rotation path. How would I go about doing this?

            {
                swordGameObject.transform.RotateAround(gameObject.transform.position, Vector3.back, Time.deltaTime * 100);
            }
            else
            {
                swordGameObject.transform.RotateAround(gameObject.transform.position, Vector3.forward, Time.deltaTime * 100);
            }```
is there maybe some sort of way to *-1 the rotation so it's mirrored?

[midnight plover]

Forward should just be 0,0,1 and backwards 0,0,-1 so *-1 would result in the same "issue". Did you try to just -1 the 100?

Right now, you are moving within time. If you want to offset it first, dont use Time related values on init.

[tight fossil]

yeah it just goes in reverse, basically the same as *-1 the vector3.directions which is what we don't want

[midnight plover]

Wait, what exactly do you want as outcome 😄

[tight fossil]

ok see the one on the left? i want it to do that but mirrored

the isFlipped == false is what's doing the one on the left, im trying to flip it so it does that with the one on the right

[midnight plover]

Okay, and just by using vector3.forward for both but one with 100 and the other with -100 does not do that?

[tight fossil]

no that's giving me the same as just using vector3.back

[keen dew]

It is mirrored, but on the diagonal. If you want it mirrored on the Y axis you can just rotate them so that they start upright (| instead of /)

[tight fossil]

i dont want them to start upright though it'd be too big a sword swing for what im trying to do 😭
i get what you mean though

[sweet mural]

I got a question

[tight fossil]

the starting point is the angle and then it goes either left or right

[midnight plover]

just ask...

[keen dew]

But how is it going to be mirrored on the Y if they start leaning to the right

[sweet mural]

sorry anyways I want to know if anyone can use c script for a vr game not sure what channel I’m supposed to put this in but mb

[frosty hound]

Unity uses C#

[sweet mural]

mb I’m new to unity

[frosty hound]

Not that new to have not known that, unless you literally took this advice and did nothing with it since last year:
#💻┃unity-talk message

[tight fossil]

im not sure man, im trying to mirror it after the lean i guess?

so it leans to the left

[midnight plover]

as a starting angle for the right one?

[sweet mural]

someone with 2+ years of experience is teaching me

so idk

[keen dew]

You're going to have to first figure out how exactly you want them to behave

[tight fossil]

i do, i want the right one to lean left and move down, which i know vector3.forward will make it move down i just need to figure out how to make it start leaning to the left instead of right, which is why im here

[keen dew]

Yeah that's the question you should've asked in the first place

[tight fossil]

so do you know how?

[midnight plover]

You need to take your starting angle and from there add your rotation.

[tight fossil]

Yeah I know, that's what I'm asking 😭

[keen dew]

First rotate one of them to the place where you want it to start. Then look at the inspector and write down what the rotation is. Then add this code to Start:

if (us.isFlipped)
{
    transform.eulerAngles = new Vector3(x, y, z);
}

Put the correct rotation values in place of x, y and z

Bonus: use a Vector3 field so you can use the inspector directly

[tight fossil]

ok i need to understand why it's starting at that rotation in the first place im not setting it, and it's not starting at 0 or anything. is it because of the angle it's already in?

[keen dew]

What do you mean the angle it's already in

[tight fossil]

well when i start RotateAround the z-axis starts at around 60~ and I don't undertstand why the rotation begins there as both it and it's parents aren't close to that. In fact just changed the Z-axis of the parents and it changed nothing when it swiped the sword it's still starting at 60ish

[midnight plover]

are you sure, no parents in combination add up to the world rotation being 60?

[tight fossil]

the parents resting Z axis is -15 but even when I changed to anything else its still starting at that 60ish lean

everything else in the hierarchy is 0

[midnight plover]

lets make it plain simple. What does your "sword" look like, when you set the rotation directly to 0,0,0

[tight fossil]

exactly how it's leaning in that gif, it's parent "holster" is at -15 causing it to be slanted

[midnight plover]

So you set the transform.rotation of your sprite (red) to 0,0,0 and its leaning?

[tight fossil]

yes

also just figured it out, i hate how bandaid it is but i cant sit here and fix this all day

[midnight plover]

is your sprite rotated?

Like the actual sprite file?

[tight fossil]

no it's straight

[midnight plover]

transform.rotation = 0,0,0 should be straight. But its not, unless you still have other scripts running

[tight fossil]

it's fine though i worked out a solution, just added a one time offset of 90 to the time.deltatime * 100

[tight fossil]

yeah i said, the parent is at -15. but the parent's rotation isn't changing the starting rotation when it rotates around

dont worry about it, its done now, thanks everyone for the help

[midnight plover]

You dont understand. if you rotate your sprite to 0,0,0, and its still leaning, that is wrong. just plain wrong 😄 But great if you found a workaround.

[tender mirage]

I have no clue why but if i reference a another integer like "number" here i don't get a out of range array error but when i do use "i" i get an out of range array error even tho the int number literally equals to "i" beforehand

//Initialize offsets
float currentX = 0;
float currentY = 0;

for (int i = 0; i < colums; i++)
{

    //Spawn button
    GameObject characterButtonClone = GameObject.Instantiate(characterButtonPrefab, partyMembersObject.transform);

    //Assign position
    characterButtonClone.transform.localPosition = new Vector3(currentX, currentY);

    //Assign name
    characterButtonClone.name = "characterButton" + i;

    //Get text
    TextMeshProUGUI nameText = characterButtonClone.transform.GetComponentInChildren<TextMeshProUGUI>();

    //If party member exists
    if (i < lobbyParty.partyMembers.Count)
    {

        //Assign name based on party members name
        nameText.text = lobbyParty.partyMembers[i].characterName;

        //Get current character
        Character character = lobbyParty.partyMembers[i];

        //For some reason this works.
        int number = i;

        print(number);

        //Add button listener with delegate based on party member
        //If i put "i" here instead of "number" i get an error
        characterButtonClone.GetComponent<Button>().onClick.AddListener(delegate { PartyMember(number); });

    }
    //If no party member exists
    else
    {

        //Remove listenrs
        characterButtonClone.GetComponent<Button>().onClick.RemoveAllListeners();

        //Disable characterbutton
        characterButtonClone.GetComponent<Button>().interactable = false;

        //Assign empty
        nameText.text = "EMPTY";

    }


    //Add to current list
    currentCharacterButtons.Add(characterButtonClone);

    //Apply offset by width
    currentX += characterButtonClone.GetComponent<RectTransform>().rect.width;

}

I'm very confused

When you use a local variable in a delegate or lambda (often with a loop), you've got to copy the value and use the copy because the delegate will only refer to a single variable even though you're expecting different instances. Something about how memory is managed.

[naive pawn]

it's not that exactly. it's that the delegate is capturing the variable, not its value.

[verbal dome]

Doing what you did int number = i; is pretty standard

[swift crag]

It's a really sneaky problem

[verbal dome]

Rider does show a warning for that, at least

Probably other IDEs too

[swift crag]

[tender mirage]

I see. I really should learn more about delegates then. As far as i knew, they were basically like a more versatile way of referencing functions.

[swift crag]

This is more of an issue with anonymous functions than with delegates in general

a "delegate" type is just a function type

[tender mirage]

I've heard that events were better to use then unity events. Is this also true with delegates vs events?

I apologize if that sounds out of field. I'm just very unfamiliar with delegates. You can probably read that.

[swift crag]

UnityEvent is very similar to a delegate-typed variable, except that it can be serialized and modified in the inspector

these two are very similar:

public event System.Action Foo;
public UnityEvent Bar;

(the event keyword allows anyone to add functions to the delegate object, but only allows the owning class to invoke it)

[tender mirage]

that could be great for learning delegates and understanding them better.

[swift crag]

i vaguely remember seeing a benchmark where UnityEvent behaved better

but this is a vague memory

[tender mirage]

i should definitely mess around with that. Thanks alot for informing me.

[tender mirage]

I see, yeah i know that came out of left field.

[swift crag]

Having a UnityEvent exposed in the inspector is really nice for when you need to tie one-off things together

like when you want to add an extra particle effect to one enemy's attack

[edgy tangle]

UnityEvents wrap a delegate under the hood anyway

But they add the convenient inspector functionality

[swift crag]

not quite!

they store a list of invokable objects

rather than modifying a single delegate object

of course, a delegate object is, itself, just a list of things that you can invoke

Every time you modify a delegate object, an entirely new object is created. This makes it safe to add or remove targets from it in the middle of an invocation

[edgy tangle]

Oh so it doesn’t wrap a delegate declaration? I thought they did

[swift crag]

I'm not sure how UnityEvent behaves, by comparison, actually..

[tender mirage]

Wait, can unityEvents take parameters like delegates then?

[edgy tangle]

Yeah they’re generic

[swift crag]

e.g. UnityEvent<int> takes an int

[edgy tangle]

But, you are limited with Inspector functionality

[tender mirage]

I'll try that right now.

[swift crag]

It's very similar

[tender mirage]

Yeah, i can imagine.

[swift crag]

if (baseInvokableCallList[index] is InvokableCall invokableCall2)
  invokableCall2.Invoke();
else if (baseInvokableCallList[index] is InvokableCall invokableCall1)
{
  invokableCall1.Invoke();
}

what's going on here 😭

[edgy tangle]

Yeah that’s confusing lol

[swift crag]

gotta check twice, just to be safe

[edgy tangle]

I’ll take a look at the API later. Apparently I misunderstood how it works

[swift crag]

It's a really pedantic difference, to be fair

As far as you're concerned, it's just like having a delegate object

[edgy tangle]

But either way, I doubt that there’s any substantial difference in performance to use a C# event vs. a Unity event

[swift crag]

yeah

[edgy tangle]

Personally I like to just use them in the way of: event for something I want to happen only on the code side; UnityEvent if I expect to have some callbacks that any non-coder could easily set up with the Inspector

[eternal needle]

the performance would rarely ever matter, it's more about if you want it serialized (assigned in inspector) or not
There's a lot of cases where I just go with c# events because I specifically don't want the functionality tied in inspector. When everything becomes tied in inspector, it becomes a little bit hard to follow the code flow because suddenly you aren't subscribing in code anymore

[swift crag]

yeah, C# events still give you some static analysis

[eternal needle]

I don't think im using unity event at all currently tbh, but thats just a preference

I do like actually seeing it in code

[swift crag]

I sometimes use both

[tender mirage]

Yeah. I suppose there's no wrong way of going about it, as long as your code base is consistent, be it with inspector unityEvents or c# written delegates.

good point honestly.

[swift crag]

a C# event for other code that always depends on the event, and then a UnityEvent for when I want to bodge something in :p

[edgy tangle]

Yes I follow a similar way of thinking

Unity Events with Inspector callbacks are very convenient to set up but can be difficult to track down for debugging

[eternal needle]

there was a point where I was making a main menu and hooked everything up through the existing button on click unityevents. It felt really bad going through that setup just to figure out what's hooked up to what, because some of these buttons are parented under a couple of objects

compared to a script on the canvas which referenced every button needed and hooked up the event in code. I could at least click on the reference and be shown which button I was using

[swift crag]

yeah, most of my buttons work like that

it just winds up feeling better to me

[midnight plover]

I started making a reflection component that could hook every method that was available by singleton patterns. That way, I did not have to drag drop any reference into every button but just assign the correct method once. Made it easier for me to decouple hierarchy objects a bit

The reflection was only happening in editor mode and later on just the static Class.Instance was called if available

[rain solar]

when generating terrain with fractal noise how do i interpolate between noise samples? when i do linear interp the terrain looks low quality cause its just a bunch of squares and i cant use bicubic because it creates wavy terrain

[swift crag]

Your noise may have too high of a frequency

if bicubic interpolate looks really wavy, that means that your terrain wants to go up and down really fast

[spare thunder]

Is it normal that with an almost empty unity project it already takes me 16 seconds each time ?

[frail hawk]

when does that occur

[rich bramble]

If your computer isn’t a potato, something’s wrong.

[spare thunder]

Whenever I make a script change or test the sample scene.

I have a good computer overall

rtx 3060

I literally just added these

I never really worked on unity. any options I should be checking ?

[humble bronze]

Uhh do you have an SSD or a hard drive ?
i know that my projects were veryy slow when i had a hard drive

[spare thunder]

SSD

[rich bramble]

It could be because Unity is a heavy editor Every new project loads a lot of things so it also opens slowly for me 🤔

[humble bronze]

idk then ;-;

[swift crag]

Script recompilation takes 3-10 seconds for me, depending on the project size

If most of the time is being taken up by asset imports, then that's a bit weird

You can go to Window > Analysis > Import Activity to look at recent import events

it'll show you how long each import took

e.g. a decently sized model took 2 seconds to import (i have some custom postprocessing happening, and it's...not optimized)

[spare thunder]

Hmm. how can I exclude some folders from import ?

[swift crag]

why do you want to do that?

are you seeing something taking a long time in the import activity window?

[swift crag]

most of these are just built-in shaders

they'll take a little while to compile, once

[spare thunder]

Seems like basic stuff, but I have uploaded some of my book's references (out of the assets folder though).

[swift crag]

Unity will only import things in the Assets and Packages folders

[spare thunder]

Hmm then it's weird

[swift crag]

nothing in here looks unusual

trigger another reimport and then look at the recent events

[spare thunder]

still 17s

[swift crag]

Don't sort by duration; sort by Last Import

that wil show you what's actually reimporting

[spare thunder]

weird, so it reimports everyrthing all the time even if they weren't changed ?

it makes no sense though, all the last imports account for like 3s

[swift crag]

Assets are only reimported if a dependency changes. Dependencies can be the file the asset comes from, other assets, project settings, etc.

what are you doing to trigger importing? are you changing a script file?

if so, that'll take a while (all scripts in the assembly, and any assemblies that reference it, must be completely recompiled)

you won't observe this in the importer window

Each import event will explain why the import happened

[swift crag]

(you will see script assets, but this only counts the time taken to look at the script file and go "yep, that's a script")

the C# compiler isn't really something the asset import system understands

[spare thunder]

Yes, everytime I change a script from the 3d empty project I have to wait 17s already?

[spare thunder]

very different from this

[swift crag]

that's a very long compile time for an empty project, for sure

[spare thunder]

So there must be a problem,

Creating a new fully empty project to test
