udon-general

[indigo wagon]

I see no reason why this isn't exposed.

Are people really laging the game by converting to vector3 then back?

I've swaped it out but I still don't understand why I can only convert to quaternian and not from.

[grand temple]

toeulerangles on a regular quaternion is definitely exposed, what are you trying to do? that doesn't look like a regular quaternion

[indigo wagon]

Transform.rotation.ToEulerAngles()

but I have an array of transforms.

[grand temple]

I feel like you're just getting syntax wrong or something. what's the larger context?

[indigo wagon]

I was trying to define the xyz delta as a vector 3 rather than a quaterniun

[grand temple]

that's not how quaternions work, you can't just subtract them

you should multiply with the inverse instead

points[0].rotation * Quaternion.Inverse(MovingObj.rotation)

[indigo wagon]

Im trying to get the change in positions tho
so I was subtracting the x,y,z,w values.

[grand temple]

yes, but that's not a valid quaternion

[indigo wagon]

DeltaX = NewX-OldX

[indigo wagon]

how, its passing in 4 floats

Swaped it over to a quaternion and its working now anyways,

x= change in x, y = change in y, z = change in z.

[grand temple]

because quaternions are not a simple vector. For one, they require adding up all 4 values to equal 1. you increase one, it decreases the others. if you just jam in whatever random values, it's not going to give you anything remotely that you want

[indigo wagon]

thats why I needed that vector3 convert that errored then,

I don't see how multiplying by the inverce gives you a vector of the change.

[grand temple]

where with a vector you would do a - b to get the difference, with quaternions you do a * inverse(b). it's effectively the same thing but for quaternions

[indigo wagon]

at least position was simple.

[grand temple]

quaternions are not simple 😅

[indigo wagon]

ah, so Quaterniuns are anoying AF, noted.

I wish that the conversion didn't error

[grand temple]

yes, you need to know how to play by their rules. they are not just a vector

[indigo wagon]

Its not giving me the exposed function error anymore

But my fixed update needs fixing.

This should work, fingers crossed

welp that didn't

I can work arround that

eluer is 3 floats not a vector3

bruh

Right, time to see if I can work arround it.

@grand temple are you 100% sure its exposed to udon#?

Becase this is giving me the error that it isn't exposed,

[grand temple]

yes, I use it all the time

idk, maybe update your sdk and udonsharp? doesn't seem like an old version issue because it's always been exposed, but maybe your version is messed up

[indigo wagon]

Bruh, I should have read the unity SDK.

".eulerAngles"

not ".ToEulerAngles()"

[grand temple]

oh that must be an old deprecated thing

[indigo wagon]

That . also lets be wright vector3 I belive.

nope, still need to do that manualy

[indigo wagon]

Bruh I'm dumb AF https://docs.unity3d.com/ScriptReference/Vector3.Lerp.html

[indigo wagon]

WAY cleaner

[grand temple]

you can also do MovingObj.eulerAngles = so you don't have to convert back to quaternion

or you can do Quaternion.Slerp to avoid the vector-based rotation altogether

[indigo wagon]

nope

That Quaternion.Slerp seems smart tho.

[grand temple]

no, not obj.rotation.eulerangles

just obj.eulerangles =

[indigo wagon]

ah, ok.
IG transform just has its own definition for that then.

cus that worked.

[grand temple]

it's because quaternion.eulerangles is only an output, while transform.euleranges is both output and input

[indigo wagon]

welp, turns out that rotation vector was useless anyways as thats not how my refrence material does it apprently.

bruhs really coded it to look at the next node.

You know what, nah, Im adding rotations to those points lol.

lets me do things like make a goomba front flip.

[indigo wagon]

I have 0 Idea how this is making an OOB error

I am litraly modulusing it by its lenth, it should never go negative

bruh, C# messed up modulus.

That should be remander 1 for all of them, anoying.

horray for google

int mod(int x, int m) {
    return (x%m + m)%m;
}```

[indigo wagon]

Cool, my code is buggy

OH LOL, both are plus

[arctic scarab]

how to work with synced variables

[acoustic vale]

Hey all, is Unity's standard assets loaded into VRChat? I'm making an Udon script using NavMesh to control an AI in the world but I want to animate it.

^ if not, i might try convert the script into U#

[brazen epoch]

My editor still isn't giving me typings for some things. I imported VRC.SDKBase and Utilities and Networking are showing that they're invalid references. This started to happen after moving to VCC

[arctic scarab]

how i repeat function every second

[brazen epoch]

SendCustomEventDelayedSeconds(eventName, timeout)

[arctic scarab]

sounds very vrchat specific

[jaunty schooner]

I'm trying to make a pickup which has a trigger collider on it which triggers an event when a player enters the trigger collider, but I'm not having any luck.

The pickup is on the pickup layer, and has the pickup and object sync components, a rigidbody, and a mesh collider.
I have a box collider set to trigger which I want to be the thing that triggers the event.

I thought perhaps having this on the Pickup layer was the issue, so I created a child object, set that to the Default layer, and put the script on it instead, but when I create a remote player in the emulator and touch the object to them no collision is detected.

I can't set the main object to the Default layer because if a player picks it up, it then collides with their body and messes with their movement.

I'm not sure if the child object needs its own rigidbody for the trigger to work, but I'm trying to read its velocity, so I added one to it. I have not added an Object Sync component to it because the parent already has one and presumably the children will follow it remotely.

[arctic scarab]

    void Start()
    {
    SendCustomEventDelayedSeconds("test", 1);
    }
    void test()
    {
        Debug.Log("e");
    }```
seem to not work is anything wrong

[brazen epoch]

Start not start

you can also use nameof(test) instead of "test" so that it will highlight the error if you change the name

[arctic scarab]

well it still not working anyway

[granite grove]

Use something like rider or resharper, it should tell you the namespace needed for that class

[arctic scarab]

so what else wrong here

[granite grove]

the spacing

[brazen epoch]

Can I get a link? Also, the scripts compile okay, just my editor freaking out

[granite grove]

Ah, in that case just close and open vsc

[brazen epoch]

This has been a multi day thing

do you also use the creator companion

[granite grove]

Are you on Linux?

[brazen epoch]

Windows

[granite grove]

Use vs instead

It's heavier but it's more stable than vsc

[brazen epoch]

I think I'd rather stick with my vscode for everything, but I can give it a try I suppose

[granite grove]

Trust me, I thought that too

Then I switched to vs

then I switched to rider (it's paid but I have an open source license) and can never go back

[arctic scarab]

i seem always have this error

[brazen epoch]

@granite grove lmao

[granite grove]

Wtf

And it builds fine???

[brazen epoch]

I really think it has to do with the VRC Creator Companion install

[granite grove]

Possibly

[brazen epoch]

yeah it builds fine in U#

[granite grove]

Weird

[brazen epoch]

Yeah I'll still need some help with this

[jaunty schooner]

I've just figured out why my trigger volume wasn't detecting collisions with the remote player I spawned in the emulator....

For some reason, in the ClientSim beta, when you spawn a remote player, instead of having the usual capsule collider, they have a small sphere collider down at their feet.

[gloomy fog]

how to make a toggle for a object that change the material

[mighty fjord]

the method test needs to be public, not sure about the error you're getting though

[vast blade]

Is it just me or is local test very bugged with throwing you in seperate instances

Like it sometimes takes me 10 attempts to get 2 clients in the same instance

[jaunty schooner]

Do remote players in ClientSim execute their scripts? I'm trying to get a remote player to play a sound and fling themselves when they detect a trigger collider held by another player touching them, but nothing happens. Or rather, I get debug messages telling me what the local player is executing, but I get no debug messages for the remote player, and if I change the code slightly so the local player can hit themselves, the code seems to be working. The sounds play at least.

[brazen epoch]

"remote" is a little weird in client sim because it's all in editor. Another editor isn't spawned so the only way to test remote players executing their own logic is to actually test in client

[sharp torrent]

is it okay to hide an object with udon scripts in it on only one platform of a cross compatible world? or will that still result in ofsetting all of the udon things
ex: hiding the video player instead of deleting it on the quest version

[topaz jetty]

happened to me too, in unity go to edit > preferences > external tools, then under "generate .csproj files for:" check "git packages" and then click regenerate project files

then restart visual studio

that fixed it for me

[brazen epoch]

I don't have a "generate .csproj files" field anywhere

Is it required to have one of the version control things installed?

[topaz jetty]

I don't

[brazen epoch]

Oh. I still had it set to vscode not vs

[worthy falcon]

Hello everyone, i'm new here. Like, super new to creating a world. I've downloaded Unity, done all the steps, but I can't access the vrc world prefab page on the documents, it gives me a 404 error. Any ideas?

[topaz jetty]

are you looking for this?

[worthy falcon]

Ah.

Thank you, yes, that's exactly what i was looking for!

[brazen epoch]

@topaz jetty That ended up working. Thank you very much

[jaunty schooner]

Does anyone know how I'm supposed to build and test with multiple clients? I have an Index. I said I want two clients and clicked the button, but two windows hung. I shut down SteamVR and it reloaded it and launched the game, but there's only one client, and I can't move with the sticks.

[topaz jetty]

check "force non-vr" so it doesn't launch steamvr with it

[jaunty schooner]

Hmm, yea, that works, though I was really hoping to be able to test offline in VR with multiple clients. But at least the remote players now execute their scripts so I can test that.

[topaz jetty]

I don't think you can test offline with multiple clients in VR, but if you have friends or multiple headsets you can upload your world privately and test it there

[coarse raft]

How do i instantiate a global object?

like

have it instantiate for all clients

I have a button that is supposed to spawn a flashlight GameObject when you interact with it, but it only spawns for that 1 client

[lavish meteor]

Trying to make a HQ/LQ Mirror toggle and i'm getting this when i make an Udon Behaviour. How do i fix this? Thanks!

[arctic scarab]

is there any way of instantiating object and making it synced for everyone

[coarse raft]

^^^

[wind atlas]

You need to create a pool of flashlights and the take out one instead of instantiating them.

[coarse raft]

wdym pool

like have them already in the scene and just tp them?

[arctic scarab]

im supposed to create 100 bullet objects to ensure they will stay synced?

cant i just spawn them in some way?

[wind atlas]

Pooling is the name of the technique people use so they don't have to instantiate a lot of objects. The same applies to bullets, if you have that many, it's usually more efficient to pre-create them and reuse instead of constantly doing something costly like an instantiate.

[wind atlas]

I think there is a VRCObjectPool component in the SDK you could use.

[autumn forge]

You know how some worlds have movies and shows, how do you make one?

[coarse raft]

is this global?

[wind atlas]

The VRCObjectPool component is. It will enable/disable objects the same for every client.

And since you upload the networked objects inside the pool with the scene, everyone can see the same ones.

[coarse raft]

k

thx

[pastel gyro]

is there a way to add subtitles for sdk 3.0 ?

[wind atlas]

Not automatically. You can use a canvas, set it to world space and put it infront of people's faces.

[pastel gyro]

how about pictures ? but like in your face

like avatar effects stuff

[wind atlas]

That depends on what type of effect you want. The concept is more or less the same though, yes.

Canvas can display text and image too, if that's what you want.

[pastel gyro]

I see, thanks

[coarse raft]

How do I call a custom event in another script?

in graph mode

nvm got it

[stable nebula]

Does anyone know if it's possible to Sync an animation?

For example, I have a world that playes a big animation, with sounds, but if you lag in vrchat thanks to someone switching avatars, the animation gets desynced, and Lags behind the sound(Depending on how much you lagged).
So my question is, is there a way to force the Animation back to where it should be with the sound, so that it doesn't desync?

[noble void]

how do I download an avatar onto vrchat? I'm trying to figure it out and I've been sitting here for an hour

[coarse raft]

https://www.youtube.com/watch?v=zX-8uW3lZUo

something like this?

You could have the animator control the audio source

[stable nebula]

oh neat, thank you!

[coarse raft]

np

[stable nebula]

Oh, sadly no, that is for Avatars, and the process there wont translate to worlds. :c

My hope, is there is a way to force an animation to skip forward to the correct time, in the timeline, to keep in sync with the audio.

[coarse raft]

if you have the animator control the audio will it not be automatically synced?

[stable nebula]

all the animator would do, is turn ON the sound, not regulate it. to my knowledge at least.

that video was showing you how to toggle the sound on, and off. not skipping the sound to match with the animation/animator.

[coarse raft]

O

[stable nebula]

many videos show things like that, but i can't find anyone who takes it a step further, and manages the audio/animation sync. :c

[coarse raft]

interesting

[magic mica]

Anyone know how to resolve this problem? Migrated and all udon sharp programs show this now

[brazen epoch]

for ik followers, will I need to loop setting object transform through scripting or can I use something else

[coarse raft]

did u create a C# script of a UdonSharp script?

[magic mica]

Ive always used create U# Script. Even does it with new ones.

Just spits out Compile validation failed, check console output for details.

I am debating whether my unity install is corrupted, the project itself is broken, or its just an issue with udonsharp when it comes to 0.23 udon sharp scripts being ran on 1.0.1

Ill give a new project a whack and see if the same or something else happens

[coarse raft]

weird. If the .cs file has a U# counterpart then idk why it would do that

[magic mica]

tried with a new project with no issues soo far. it just seems it doesnt like legacy projects

[coarse raft]

damn

[magic mica]

Been through 5.6.3p1 til now. guess it was to bust eventually

[coarse raft]

have you tried selecting the U# file and recompiling?

and does it have the correct source script?

[magic mica]

yes with nothing happening

plus i rather just go ahead and start a new project and slowly import everything to see what causes it to bust

[coarse raft]

yea ig

[magic mica]

probably will do it tomorrow since ive been at this for 12 hours haha

[coarse raft]

fs, good luck bro

[native dagger]

Hi, I bought a ship that I really like and trying to modify it into my home world.
After fixing the collider toggle. I found out the collider will spin me around when I touch them.

This is a recording of what happened.

Searched around and didn't find similar mention of this problem. Does anyone know what causes this?

[grand temple]

probably has a rigidbody, don't do that

[native dagger]

Thanks, let me check

Fixed, thank you very much.

[wind atlas]

Do you want to sync both, animation to animation between players and animation to audio locally?

Animation to animation can be synced by sending the start time in a manually synced object and then fast forward the animation according to that. If you use an animator, you'd use animator.Play, it takes a value from 0 to 1 to jump forward in the animation.

Animation to audio I'm not 100% sure, but you if you use Timeline, I think you have to select DSP clock. This way lag won't have an effect for the animation.

[arctic scarab]

is there way to sync instantiated object

[indigo finch]

Quick question, trying to convert my graph script to a udon# script; but how would I get the gameObject from the last object the pool spawned?

[wind atlas]

No, there is not.

[arctic scarab]

ok then

how can i play audios

[wind atlas]

The method returns a value, so you just have to do:
Gameobject spawnedGO = pool.TryToSpawn();

[wind atlas]

Make a reference for an AudioSource, then call "Play" on it.

[indigo finch]

ah, thanks ^^

[arctic scarab]

codeee?

[wind atlas]

myAudioSource.Play()

[arctic scarab]

is there way to play randomly one of many audios

or i have to generate random number and pick audio based on that

[wind atlas]

Yeah, you can use Random.Range to get a random value and then just use that as an index for an array of AudioClips.

So: myAudioClipArray[Random.Range(0, myAudioClipArray.Length)]

Then assign the clip to your audio source before you play it:
myAudioSource.clip = myNewClip;

[arctic scarab]

okay i dont know how path to this should look like

[wind atlas]

What do you mean by "path"?

[arctic scarab]

i need to specify audio path to make script play it isnt it

[wind atlas]

Again, what do you mean by path? You usually just make an AudioClip reference in your script.

[arctic scarab]

nono i mostly use find

[wind atlas]

Find is to find stuff in the hierarchy. AudioClips can't be found there. You have to drag and drop them into your script in the inspector.

At least in Udon it's not possible to read assets directly from your folders. (afaik at least)

[arctic scarab]

ok then how i reference

[wind atlas]

Do you use udonsharp?

[arctic scarab]

yes

[wind atlas]

Just create a field variable.

[arctic scarab]

how

[wind atlas]

Have you never created field variables before?

Like:
public int MyValue;

[arctic scarab]

i always specified them

but pretty sure thats not int

[wind atlas]

https://www.youtube.com/watch?v=h8nvR2YbzBc

Just do this but with AudioClip[]

[arctic scarab]

    public AudioClip bounce1;
    void OnCollisionEnter(Collision collision)
    {
        bounce1.Play();
    }```

whats wrong

[wind atlas]

AudioClip != AudioSource

[arctic scarab]

ah i do want audiosource i dont cut anything from audio

[wind atlas]

It tells you that the object you are using has no reference to any instance.

So you are trying to call Play on a missing object => you don't have any audio source.

Go to the inspector and assign one to use.

[arctic scarab]

i placed it it reset itself

actually i cant even put it in now

probably because its audio source now

why cant i insert it

mp3

[wind atlas]

Again, AudioSource != AudioClip

[arctic scarab]

so i wanted play audio source directly

[wind atlas]

AudioSource is like your head phones and the clip is the actual audio you want to play. Try creating an audio source in the scene and you will see it has a clip that you can assign to it.

https://www.youtube.com/watch?v=6OT43pvUyfY

[arctic scarab]

but i have to make multiple audio sources then

if i want to play one randomly

[wind atlas]

You can assign clips in the code too. Look at the code I wrote before:

#udon-general message

[arctic scarab]

im having pain with ;

    void OnCollisionEnter(Collision collision)
    {
        c = Random.Range(1, 2);
        if (c == 1)
        {
            a.Clip = bounce1;
        }
        
        if (c == 2)
        {
            a.Clip = bounce2;
        }
        a.Play();

    }```

how i fix

[wind atlas]

Use Visual Studio or something and set it up so it shows you intellisense.

[arctic scarab]

it doesnt

i checked

[wind atlas]

Set it up so it does.

If you do, it will underline "Clip" with red. And it you type in "a" and then a dot, it will show you all possible things you can use.

It will show you "clip" is the right spelling.

[arctic scarab]

hate unity

how i make sound from object direction

currently it plays like global

[arctic scarab]

i turned mono to stereo just in case

[lilac hatch]

Eyop, i'm having an interesting issue with the videoplayer at the moment.

Sometimes everything work fine and I have nothing to say, sometimes people come to me with a veryw very specific issue

As is:

2022.05.23 21:14:57 Error - [Video Playback] ERROR: [generic] Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)> (caused by URLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')))

I understand that this is apparently an ssl error which is not surprising me since I use zerossl for it, but the way to fix it is very dumb and I honestly don't get it

If I have the person having the issue visit the website on a web browser, it simply suddently start working

I'm unsure if it's an issue with youtube-dl, avpro or my setup at this point tbh, or even windows cache system

[lilac hatch]

well, w/e, I just ended up re-doing my entire ssl setup and it's fine now

was on my end 👁️

[cursive cipher]

Shot in the dark, letsencrypt?

[lilac hatch]

I forgot to merge the CA and the certificate together for nginx so it was missing parts of the chain

5am drunk SSL mistakes

[cursive cipher]

yep

was just about to say it sounded like a CA cert chain issue

I just did an overhaul of the ssl setup at work and ran into SO much of this kinda thing on systems other coworkers setup

mixture of our proper ssl, out of date letsencrypt setups...

out of date cert root stores

[arctic scarab]

can i change object shader with code

[inner sorrel]

What are the Axis names for movement and looking? I can't use the Input Events since I need something to happen every frame, but have little idea on how to get the values without the Input Events. I know there's a GetAxis method, but requires a string.

Well, I figured out the movement Axis ("Vertical" for forwards and backwards, "Horizontal" for side to side) but I still haven't figured out the names of the right stick.

Figured out a workaround. Just have the Input Events write to a float, then use that float for the other things.

[brazen epoch]

do ik followers in worlds require event loop scripting

[pallid roost]

You can swap the material, which could have a different shader on it

[arctic scarab]

actually i wanted just to change material

[rotund agate]

Anything that can help me learn udon

[arctic scarab]

udon bad

use udonsharp

[indigo finch]

udon# is nasty for beginners, with heaps of things that are unintuitive (Literally took me a year to learn how to do the equivalent of the 'on variable change' event node), but in return you get a more powerful and faster coding structure to use.

I would recommend learning udon graph, and then learning how to do the equivalent in udon#. Then you at least know what you should be able to do, and are able to ask questions about converting that are less convoluted and much easier to answer

[valid wraith]

How would y'all going about making a hand menu for your world? I have seen instances of this where when you hold your hand palm up it blinks in, and I have found a package that lets you attach things to various player bones... but I still really don't know how to go about it.

I found this unity tutorial, about making worldspace VR menus, and I have messed around with some of the followPlayer scripts.... here.

[undone moon]

Is it possible to change player's scale in udon? I was looking through the Player API and it doesn't seem to be a thing, but I wanted to double check

[coarse raft]

Random.Range does not include the max value

so you wanna do Random.Range(1, 3);

also, make sure c is defined as an int

[dawn forge]

Second this, also looking to temporarily force or require a specific avatar in order to participate in a "session" of the game I am wanting to create. Hoping to know soon so my motivation can skyrocket to make a gamemode system for a very run VR arena experience.

If anything, I can sort of invoke a VRC Avatar pedestal equivalent to a player interacting with it, so I can get them into that avatar and then read for key data periodically to ensure the user is in the preferred avatar for the map and boot them out of the arena until they use the avatar to ensure no large/tiny or invisible avatars are there to ruin the experience

[undone moon]

We need a Udon Unleashed that lets dev's go crazy

I keep trying to do extreme locomotion stuff and udon really hates it

[dawn forge]

The reason they made Udon unfortunately rather than expose the whole MonoBehavior which I can understand security risks, but also I know they're still trying to whiteliest and expose more methods and API's they deem safe... I started Unity with modding Empyrion and there is a lot of impressive features devs can crank out when you're not restricted.

[worldly tapir]

Not an udon question.
#user-support-old
Also please don't use voice changers.

[plain oasis]

How do I get Horse Animset Pro hooked up in Udon, I wanted my first VRCHAT world to have rideable horses ever since I saw videos of Primal Valley (Skyrim like world)

https://assetstore.unity.com/packages/3d/characters/animals/horse-animset-pro-riding-system-79902

[wind atlas]

That asset itself will not work in udon. You need to convert the logic from C# to Udon. Udon is very limited though, so it might not even be as straight forward and may require you to change many things.

[plain oasis]

Alright, it’s no wonder why I have trouble setting it up on VRChat, thanks for the advice.

[vapid thunder]

Hello everyone,
I need some help with a Udon project I want to create

💵 I'd be happy to pay anyone who wants to help me 💵
Please write me a message and I'll explain you the project in detail.

Thank you so much!

[arctic scarab]

can i control position of held object

[dawn forge]

You could manipulate the child object position of the object being held.

[arctic scarab]

i mean if not possible to manipualte directly then i just insert second invisible object and change position of this

[trail hazel]

is there a way to prevent a pickup being dropped

[arctic scarab]

doubt

player controls what he holds

but you can make item position near player all the time

[trail hazel]

sad

i want to try and override the right click action and make dropping pickups a separate thing

[arctic scarab]

you can always make world vr only

[trail hazel]

don't really want to do that lol

[rough beacon]

been some time working with ui. how make ui clickable again?

[plain oasis]

I’ll try UdonSharp out

[rough beacon]

do you like it? 🙂

Never mind. i am good now!

[broken bear]

I'm trying to get the tracking data of a random player in an instance, it works solo, but with 2 test clients it only grabs the instance owner, 3 test clients it only grabs the first 2 players (random works). Shouldn't it get # players (3), reduce by 1 for the array (2), then get #s [0, 1, 2].

[coarse parrot]

Nevermind I was wrong.

[coarse parrot]

Nope. actually I was right.
Random.Range with int argument is [inclusivemin, exclusivemax], you don't need to subtract 1.

[broken bear]

hmm wouldn't it output 0-3 though? if I feed 3 into the vrcplayerapi[] with 3 players, that would be 0,1,2? I'll try without the subtraction

[coarse parrot]

Exclusive max is it doesn't include the max number into the random.

[broken bear]

ah interesting, let me try

worked, thank you

[sharp laurel]

Guys, is it possible to set HP to all players in instance? I saw CombatManager is depricated and now I am kinda confused how should I do it

https://gyazo.com/cbd69d49850e7785f77c61e868ee5232 Can anyone tell me why my video player is giving this error? Im not sure how to fix it.

[pallid roost]

Video player don't generally work in the editor as they don't have access to the url resolution portion of vrc

[lucid geyser]

Ohh okay. So the only way to actually test it is in game/ test mode?

[pallid roost]

Generally yes. What video player are you using?

I found that, at least with the UdonSharp player you can use the quest url resolver to put videos in to test on editor.

Very handy for testing out audiolink stuff

[lucid geyser]

Im using the Udon Sharp Video Player. I was watching a tutorial on how to set it up but he didnt tell us how to edit it.

[pallid roost]

I'd you put this url Infront of a YouTube url it'll work in the video player in the editor
https://t-ne.x0.to/?url=

So like
https://t-ne.x0.to/?url=https://youtu.be/nMGw85hvNKY

[lucid geyser]

Ill try that out :3

Thank you so much ❤️

[pallid roost]

Np. Glad to help

[grand temple]

you need a collider to use interact

[coarse raft]

Is it possible to access/assign custom data to players?

So I could make something like a inventory system or stat tracker

[grand temple]

you can use playertags, but that's not synced. Typically if you need it synced you should use or create a playerpool that assigns a unique synced object to each player, then you can put whatever variables and behavior you want on it

[coarse raft]

assigns an object?

so like

an empty GameObject?

[grand temple]

an object with an udonbehaviour

[coarse raft]

ok

where is this GameObject stored?

[grand temple]

just somewhere in the scene

[coarse raft]

How would i access the object

[grand temple]

you would typically have a central udonbehaviour that manages the pool, and you could have helper functions that take a playerapi and return a reference to the corresponding behavior

cyan player object pool is one prefab that does all this https://github.com/CyanLaser/CyanPlayerObjectPool

[coarse raft]

oh ok

ill check that out, thx

[lucid geyser]

https://gyazo.com/605742d8fd658e39a19556957a577ba2 So the video thats on the player is infinitely retrying

Im not sure why.

can anyone help?

[topaz jetty]

USharpVideo actually has a built-in script that uses VRC's youtube-dl exe to resolve youtube URLs (https://github.com/MerlinVR/USharpVideo/blob/master/Assets/USharpVideo/Scripts/Editor/EditorURLResolverShim.cs), but the youtube-dl's exe name downloaded by vrchat changed from youtube-dl.exe to yt-dlp.exe about half a year ago, so older versions of usharpvideo don't really work with that, so you need an updated version (or just replace the old script with the new one, or just change the path inside the old script by replacing youtube-dl.exe with yt-dlp.exe)

For other video players you can just copy that script anywhere in your assets and it should work

[true pumice]

Hey all, very new to Udon and world building, 2 quick questions, if I want an audio source to play when a player enters a trigger collider, should I place that audio source on the trigger? and I want to set it up to where the audio only plays when the player enters the trigger for the first time, not a second time, how does one go about doing that?

[topaz jetty]

in udon create an audio source variable and a bool variable and set the default value to false, then add the event on trigger enter and use the branch node to check if the bool variable is false, if it is play the audio source and set the bool variable to true

Now when the audio has played the variable will be true so it won't play next time because it only plays when it's false

[true pumice]

Again very new sorry lol im assuming if the bool variable checkbox is off its false or is that true?

[topaz jetty]

Checkbox off is false

[true pumice]

Last thing im confused about, have everything set up as described, now what node do I need to connect to the block node to switch the Played variable to true?

[true pumice]

Nevermind, I forgot youre able to hold ctrl while dropping variables lol

[strong kernel]

Heya! How do I change the Pixels of a Texture via Udonsharp?

I already found SetPixel and texture.apply, but when I run my code to fill the texture with Color.White, it just does nothing.

Oop. Wait a sec. It appears my texture isn't readable.

Okay, yeah. Still nothing.

Just gives me

UnityEngine.Texture2D:SetPixel (int,int,UnityEngine.Color)```

The relevant code snippet

      for (int y = 0; y < texture.height; y++)
        {
            for (int x = 0; x < texture.width; x++)
            {
                Color newColor = new Color(1.0f, 1.0f, 1.0f, 1.0f);
                texture.SetPixel(x, y, newColor);
            }
        }
      texture.Apply();```

[arctic scarab]

wait is udonsharp avaiable for avatars

[coarse parrot]

No. What made you think that way?

[coarse parrot]

How did you create the texture object? The texture format should be RGBA32 if you want to use SetPixel method

[strong kernel]

I just have a PNG I use as a texture, then put that in via a public texture2d.

[coarse parrot]

Can you show the settings for the png?

[wintry parcel]

hi

i can't search anything

the bar is gray

any help?

[arctic scarab]

because avatars use udon graphs too

[coarse parrot]

I think you confused with the Animator Controller

[scarlet lake]

https://prnt.sc/O3WuJsW0TAOS I get these error messages when trying to build test or publish a world, I'm not familiar with publishing worlds but the package is an upload ready yet I don't know what to do after getting these errors! please help

[coarse parrot]

If you can upload, that error doesn't matter

[scarlet lake]

Gotcha somehow I think the publishing is working (maybe haven't tried) but the build test is asking me to use an application to open it with using microsoft app store owo?

[coarse parrot]

It shouldn't be. Take a look in sdk panel Settings, and see if VRChat client path is correctly set.

[scarlet lake]

I'll take a look, i'm a visual learner so it's a bit difficult to understand without seeing what exactly to do step by step

[coarse parrot]

As in the screenshot

[scarlet lake]

yes everything is the same

not sure exactly what it is

[coarse parrot]

How is the Installed client path?

[scarlet lake]

I've uploaded it, it looks fine also how do you mean sorry client path?

[scarlet lake]

empty owo

https://prnt.sc/luMBE6qkB1vB

[coarse parrot]

You need to set to your game exe

[scarlet lake]

shall do!

[coarse parrot]

The build and test will launch the game with this path. If empty, it just doesn't know what to do

Build and publish is still fine though

[scarlet lake]

yea I'm familiar with it with avatars, usually with worlds I just turned into a 2 bit block-head when I try new things, update it works now!

thank you < 3

[unborn hornet]

Also, make sure in the console tab, that you have "Error Pause" turned off.

[coarse raft]

Am I not able to set a rigidbody's velocity in U#?

Or do I have to do it differently than in a normal Unity project

Or do I have to network it somehow? I cant really find any documentation on this

[coarse parrot]

How did you do?

[coarse raft]

private Rigidbody rb;

    void Start()
    {
        rb = GetComponent<Rigidbody>();

        rb.velocity = Vector3.forward * 10f;
    }

it has a Rigidbody component on it

[coarse parrot]

It didn't move?

[coarse raft]

not at all

I also have a VRC Sync component and a VRC Station script, but removing both of those didn't change anything

[bright canyon]

can some one help me ? i dont have any errors and idk what to do anymore

[coarse raft]

are you on the right unity version?

[bright canyon]

2019.4.31f1

[coarse parrot]

Those shouldn't be an issue. Try FixUpdate and see if the velocity is constant

[coarse raft]

idk how that would be different, but ill try

still dont work

[coarse parrot]

Does the console report any error?

[coarse raft]

none that are relevant to this issue

i think

ill ss

[coarse parrot]

Are there only those?

[coarse raft]

wait there are more

idk what they mean tho

something about the udon editor

[coarse parrot]

Probably those. Click on it and see the detail below

[coarse raft]

Object reference not set to an instance of an object

Can the script not access its own Gameobject

?

[coarse parrot]

That one is from a different script, it's calling VRCPlayerAPI which doesn't exist in play mode.

btw how did you test?

[coarse raft]

wait thats for a different gameobject

Unity debug mode AND the SDK's build and test

is there a different way i should test

this is the error for the correct object

same thing basicaly

[coarse parrot]

There's also cyanlayer's emulator you could try

[coarse raft]

oh

ive never heard of it

[coarse parrot]

So if that's the error from the correct object, that'd prevent the script from continuing to the rigidbody part

[coarse raft]

i dont really understand the issue tho

whats producing the error

[coarse parrot]

When using VRCPlayerAPI, player doesn't exist in unity test play, so it can't call any method related to player

You need to either test in game or using cyanemu

[coarse raft]

I do test in game

and it doesn't do anything different

Im not even accessing the player tho

[coarse parrot]

It's probably having different issue too.

[coarse parrot]

So you said Player.SetVelocity wasn't what you did?

[coarse raft]

no

it's attached to a gameobject

[coarse parrot]

Can you show the game object inspector panel?

[coarse parrot]

And the script content?

[hollow folio]

Try "Reload SDK" from the SDK menu, I keep having the same issue for some reason and that fixes it (until it happens again...)

[coarse raft]

the Gameobject and Rigidbody are just referencing the object that the script is attached to

[coarse parrot]

Try without private modifier

[coarse raft]

k

for the FixedUpdate(), right?

[coarse parrot]

Yes. Just void FixedUpdate()

[coarse raft]

but doesnt that just imply that it's a private function

[coarse parrot]

Empty access modifier has different access level from private

[coarse raft]

unless U# changed it, it should be the same

either way, no difference when I removed it

[coarse parrot]

Let me test a bit

[coarse raft]

ok

[coarse parrot]

Could you take a look in compiled assembly code?

[coarse raft]

tbh i dont really know how to read this

[coarse parrot]

Seems no problem but doesn't match with the error we saw before

[coarse raft]

wdym it doesnt match..?

[coarse parrot]

Another one has a part that seat player onto the station, so that's probably from a different script

[coarse raft]

yea

[coarse parrot]

Ok I see. IsKinematic stopped it from changing velocity

The kinematic rigidbody has to be moved with MovePosition

[coarse raft]

how is that possible. If it's kinematic it should be able to change its own velocity...?

is it just different in udon?

[coarse parrot]

No. I read in unity documents

Kinematic doesn't go into any physic calculation. Velocity also not included.

[coarse raft]

hmmmm

alright, thanks

nvm got it

public override void Interact()
    {
        Networking.LocalPlayer.UseAttachedStation();
    }

i didn't realize that UseAttachedStation was a method

[grand temple]

you have an option called error pause enabled. You should disable that, as you're bound to get some udon errors when there aren't any players and udon tries accessing players. You can safely ignore those errors

[scarlet lake]

Where is that?

[grand temple]

in the console tab

[scarlet lake]

sorry i'm a visual learner can you show me?

[scarlet lake]

Right thank you attempting it

That seemed to work!

[junior vine]

I am trying to get the capsules in an object pool to follow players but I was only able to get it working locally, I tried this setup but it doesn't seem to work so I'm a bit lost. Anyone know how to go about this?

Here is a screenshot of what I'm going for.

[west dagger]

Is it possible to take manual control of avatar hand positions/IK targets through udon? Like if I have a world with a weapon system and hold a two handed gun with both hands, and I pull my front hand away from the gun model, I'd like to see my virtual hand remain connected to the gun (assuming I am still holding the grab button). Anyone know if there are examples of this or if this can be achieved? Basically I want to get between the player's tracking data and avatar rig somehow and override it. I know a Station can override tracking data so I imagine that's the key somehow, however I don't want to use an animation I just want to override the IK. Hope this makes sense

[hollow folio]

My project seems to be getting stuck on an import in SerializedUdonPrograms and then goes into an infinite import loop. Any ideas how/why that happens?

[indigo finch]

you need to say when you want the transform, set position node to be called. In your case, create an event, update node, and plug it into the arrow slot of the transform, set position node.

[junior vine]

Ohhh, that makes sense lol. Thank you! Now I just gotta get the tag part working.

[slate orchid]

Hi i saw Vowgan video on Object Spawning and i was wondering how i would go bout having it so when someone picks up a gun a new one spawns in right away

[worldly tapir]

Many ways of doing this.
Do you want this to be networked? Optimized and limited? As simple as possible?

I think the easiest way, non-networked, would be to just have a script fire on pickup, reference a public gameobject (that weapon) and Vrc.Instantiate it.

The safest way, also easy for networking, would be spawning the max amount of weapons somewhere and just teleporting a gun that isn't being held to the spawn position when one at that position gets picked up (e.g. leaves a collider or, again, you check for the event)

[paper plinth]

Yee
Put all the guns somewhere
When someone picks up a gun, check if there's a gun in the space and if there isn't one there, put one there, the next one in the array.

[worldly tapir]

Extra points if you instantiate them on demand if none are free and there's gun "slots" left, and keep track of their transforms in a single object somewhere that manages networking for them, but i think that's a little out of scope from what you wanted xd

[gaunt swift]

I was playing vr chat and i didnt know if people could see me

i am getting this error and after about 3 hours of work, will i need to redo everything. System.IO.FileNotFoundException: C:/Users/NICHOL~1/AppData/Local/Temp/DefaultCompany/avatarworld/scene-StandaloneWindows64-SampleScene.vrcw does not exist
File name: 'C:/Users/NICHOL~1/AppData/Local/Temp/DefaultCompany/avatarworld/scene-StandaloneWindows64-SampleScene.vrcw

i am using 3.0 world build

[scarlet lake]

So I am using this graph here to start an event when a player enters an area

The event it starts is a door opening when the player gets near it, then it closes when they are away from it (controlled by a box collider set as is trigger) now, while it does work there is an issue, if two players enter the zone at once, it completely messes it up, for example if i walk to the door and it opens then someone walks up to the door before i leave, it will close it and mess up the cycle

Is there a way I can make it so the Door will remain open until the player leaves the zone even if another player enters the zone?

for reference, this is the event this graph above starts ^

[fiery yoke]

You need a counter (int variable) that gets incremented when a player enters the trigger, and decrements when a player leaves the trigger.
When that counter is 0 it means there is no player currently in the trigger. If its > 0 then there is.

[scarlet lake]

do you have an example of how I can do that? or where do i plug that in?

[fiery yoke]

I wont give the solution away more than I have. Ask more detailed questions of what is unclear to you.

[scarlet lake]

I am not really sure how to set up a int variable counter to be exact

[dreamy talon]

Hi hi! I have a quick question Im having this error and I cant seem to find a fix for it

its there in the vrc sdk udon script but its saying its missing in unity

any ideas?

[coarse parrot]

For what reason your Udon is in the "Old" folder?

[dreamy talon]

This is my 3rd iteration of my world, so to keep everything tidy I set all of the old assets and scripts in the old folder

would that create issues?

[coarse parrot]

Very likely if you updated the sdk or changed unity version.

[dreamy talon]

I did update the sdk, I'll move it to the main asset folder and check back with results

found out that doing the old folder and not deleting the Udon or sdk in the old folder created a new udon folder in the newer folders so it looks like it created a redundancy

deleted all the udon folders and the related sdk folders

re-importing the sdk back in now

[coarse parrot]

Should never move imported folder, for updatability, and in case of some asset has scripts that expects some specific path.

[dreamy talon]

YEP

Just got fresh new errors xD

in the arms of an angel

[dreamy talon]

I will keep this in mind for future updates ty

[scarlet lake]

Iv been following a tutorial for making a door that opens and closes, I just changed it so instead of a button, its a zone. i dont really have much idea on how to do things like a counter or how to set that up. My knowledge is basically just limited to things iv learned from tutorials. If there is a tutorial out there somewhere, I'd happily take the time to learn it but I dont really know where to start

[coarse parrot]

How was your attempt at making a counter?

[scarlet lake]

Failed. I have no idea how to do it

I got as far as making an int variable but I have no idea what to do with it

[coarse parrot]

That's the start at least.

[scarlet lake]

I hardly understand udon. I only understand somethings because of tutorials

So if someone tells me what needs to change to make something work but not how to change it then I'm pretty much screwed xD

I have only been able to learn through people showing me

[coarse parrot]

You can do trial-and-error learning. Do some experiment with things and observe its behavior

The overlay is "when something happens, do some action". So for now, reduce your scope to just making the counter work: increasing and decreasing the counter when player enters and exits the area.

[scarlet lake]

Yeah that seems to be my route for now

Just wish there was more tutorials out there for the little things you know what I mean?

All the little things is what makes the whole system work so each one is important to learn

[coarse parrot]

Have you take a look in the sdk example. There could be something useful

[scarlet lake]

Good idea

I'll have to try Tommorrow since I'm off to work now

How to get player camera ? or how to set visual layers on camera ?

[hollow folio]

How do I set a gameobject's transform? I can't find a relevant Udon node for it. I can get the transform, but not set it.

[signal yarrow]

gameobject and transform is bounded, cannot set new or remove

binded .

[hollow folio]

... that would imply you can't move objects...

[floral dove]

Set the position, rotation or scale of the Transform rather than the Transform itself. Get the transform, then set the property on it. If the target GameObject is affected by Physics, then get its Rigidbody and set the position, scale, rotation, velocity, etc on that instead.

[hollow folio]

Huh, I always thought of the transform as a component on the object and not what you'd control. I'll try that, thanks.

[fiery yoke]

A "Transform" is a component. Every GameObject in Unity is forced to have one. The GameObject itself is more or less just a container for components.
However you dont change the component itself, but the data it contains, like its position.

[hollow folio]

Right, it's just in my head you'd reposition the gameobject, as opposed to pushing new data into the transform component, which does make sense now that I think about it.

[signal yarrow]

is there any open source udon sharp game projects we can learn? Just read the documentation is not enough. and tutorial videos are usually quite simple, just something like "switching mirrors"🤣 .

[steel remnant]

There's prefabs you can try to learn from I guess.
https://vrcprefabs.com/

this page also has some nice guides.
https://vrclibrary.com/wiki/
(mainly Unity general stuff)

[signal yarrow]

vrcprefabs is great! but i can't find any udonsharp reference on vrclibrary?

[hollow folio]

Is there a way to delay an udon script's execution process, or should you exclusively use sendcustomeventdelayed for that sort of thing?

[flat anchor]

Hello there, real quick question, I am spawning gameobjects (simple cubes) unsing instantiate and want to despawn them after a delay, but cant find the nodes for despawning or how to set a delay.

[hollow folio]

Hah, we both have delay questions it seems.

[flat anchor]

Yup, I have seen the delay on custom events, but I dont even know how I would need to set custom events for individually spawning objects.

[wind atlas]

You use Destroy to get rid of GameObjects. The second argument is a float for the amount of seconds to wait, which is what you seem to want.

[wind atlas]

You could also create your own timer and decrease it each frame and check if it's done. That gives you a bit more control than SendCustomeEventDelayed. I don't know if there are other ways. I guess you could use the animator, but probably not what you want.

[flat anchor]

I see, but I only seem to find the Event OnDestroy, can you elaborate ?

[wind atlas]

I assume you use udon graph? I'm not sure how to search for that on there.

[wind atlas]

This is what you are looking for: https://docs.unity3d.com/ScriptReference/Object.Destroy.html

Maybe try searching for Object and then Destroy?

I think you can press Tab to get a more indepth search for udon graph. I don't remember the actual hotkey though.

[wind atlas]

I'd definitely recommend checking out any examples in the SDK and any example projects in the documentation.

[wind atlas]

They had this one: https://docs.vrchat.com/docs/obstacle-course

And this one more recently with the new udon sharp version: https://github.com/vrchat-community/VRChat-Joke-Jam

[flat anchor]

Hmm .. I dont seem to have access to Destroy in the node system, have you ever tried using it in C#?

[wind atlas]

Yeah, it works in U#.

[wind atlas]

You have to use Tab for the bigger search

I just tested it and it appears there

Alternatively it's located under this:

[flat anchor]

Oh! I see it too. Didn't know there was different types of searches (for performance I guess).

@wind atlas One suggestion form your side please (as you seem experienced). I know how to code, but I am just starting to learn about all the methods available and thought by starting with the Udon graph it would be easier learning everything or should I stick to U# from the start?

[wind atlas]

Honestly, I have no idea what's better. It's probably fine to just start with U# if you know how to code. The actual calls are pretty much the same, as you can see from the Destroy example.

[hollow folio]

SendCustomEvent doesn't work here so I assume I'm doing it wrong... as this was my original attempt at a delay.

[wind atlas]

I think using U# is probably also more interesting because you can go through the code a bit easier and see what's available. For example, which methods can be overwritten etc.

[wind atlas]

Can you describe what is not working?

Are you getting any errors?

[hollow folio]

No errors, the Custom Event part doesn't fire.

[wind atlas]

Check that the string is exactly the same. Also, I think the send event node should show you the event strings in a drop down.

So you don't have to assign it manually.

[hollow folio]

Oh, I think I see the issue. I've named the variable with the correct string and not actually given that variable a string. I'll correct and try again.

Ayyy, that was it.

[pallid roost]

Imo it's easier to just use U# if you know basic coding.
Once you have it in visual studio you have code completion which makes it easy to figure out what sort of methods everything has.

[hollow folio]

I'm on like day 1 of using Udon so it's all a bit magic still at this point, despite being familiar with code outside of this.

[flat anchor]

You can also skip the assigning a value part by using a Const string input. (I think)

[wind atlas]

Oh... Yeah that's why that part looked a bit sus to me. Stuff like that is also an argument to just jump into U# if you know coding. Some things are not as convenient and you have to learn how to do it in graph. I know for loops look super weird in graph but are very easy in code.

[hollow folio]

Yeah, loops are always a pain in visual blueprint systems.

[flat anchor]

Good point, is there a documentation on how to properly setup your VSCode?

[pallid roost]

I'm not sure about for with vscode, I use Visual studio.

[unreal comet]

Idk if this is an udon question if not pls tell me where to ask this question but is audio link gonna be able to work with quest soon?

[pallid roost]

For visual studio there is a project project created in the root of the project directory you can open that had all your scripts in it

[coarse parrot]

Pretty much you need C# extension by Microsoft and it's good to go

[coarse parrot]

Audio link is quiet a heavy system, I doubt that's going to work well in quest

[unreal comet]

I heard from a friend that audio on avis is gonna be available for quest users but Idk if that's true or not

[coarse parrot]

There isn't any official statement about this. So probably not true

[unreal comet]

Damn I been wanting that to come to quest

[pallid roost]

There is no way audiolink would work for quest Avis, as it requires a shader that supports audiolink and you only get the vrc mobile shaders on quest Avis.

[valid sapphire]

So, I'm setting up an event for an RP server, and Im trying to add guns you can pick up and fire. Has anyone done this before and can that same anyone send me a screenshot of what your udon graph looks like?

Edit: NVM figured it out im just dumb

[hollow folio]

Is there a way to tween object positions with Udon rather than having to use animations? e.g. being able to lerp between <currentposition> and <newposition> etc.

[tawdry minnow]

Hello is there any tutorials show me how to make projector effect like this in vrchat?

It look so cool

[cursive cipher]

I've not found any tutorials, but i have found this asset that folks have been using, may be able to look at its code to figure out how its done

[slate orchid]

whats the bit of code that will bring objects a player is holding through the tp

or how would i do it

[plush patio]

This may be confusing to ask, but is it possible to make a automatic timed toggle?

An example of what i mean is like this

Imagine 3 game objects in 3 different locations, Object A is the only one active while the other 2 are inactive, After a set amount of time (say 30 seconds) Object A Becomes Inactive But Object B becomes active, and then 30 seconds after that Object B goes inactive while Object C becomes active, This cycle keeps going in 30 second intervals

[plush patio]

I know it might have something to do with timer delays, but is there a way to have them trigger automatically

[plush patio]

Thank you so much! This is currently for a makeshift subway system for my next map, where if the subway car is at a station, you can hop in and when time is up it "Moves" to the next station

However what really happens is when the subway "moves", it actually just dissapears having a collision teleport replacing it, teleporting the players to the next subways location

I already had the collision teleports figured out, it was all about how to get it to function automatically at a fixed amount of time

[signal yarrow]

does owner can be set to null ? owner is automatically set to the first player, but i want the object has null owner at initialling.

[fiery yoke]

Every networked object must have an owner at all times. And this is by design. I dont know what youre trying to do, but you should probably reconsider how youre approaching it.

[slate orchid]

@fiery yoke could u help me? in #world-development did vrchat change the VRCPlayerApi

[fiery yoke]

No I cant, I have never used CyanEmu. Usually this just means that something is on the wrong version, either Unity itself, the SDK or any other external things you have in the project.

[slate orchid]

this has nothing to do with cyanemu i'm on the right sdk and unity idk what it would be

[plush patio]

I have 2 questions about this,

1. Is there extra steps to make this synced for everyone in the world? Or do you just need to press that sync button on the left?

2. Is it possible to do this type of function in reverse? (When the game starts, Object A is the only one inactive and the other 2 are active)

[signal yarrow]

is there any way to debug breakpoint in udonsharp?

[hollow folio]

Odd. I have everything loaded in VS2022 and most of the audiocomplete and lookup works, but random things like PlayOneShot seem to be missing. Any ideas why?

I get PlayClipAtPoint, but not PlayOneShot?

[signal yarrow]

use object ,not class .

C# basic knowledge

[pale drift]

Is this the correct way of changing an objects position with udon? i dont have any compiler errors. when i build and test and try clicking the button i have linked with it, nothing happens

[signal yarrow]

why not use an array 😅

[pale drift]

idk, this is just the way i thought of. im still beginner coder. ive used arrays before but its been a while

ive been finding prefabs for most the stuff i need for my world, but not for horse racing, so im trying to code my own'

[signal yarrow]

it's a single frame loop, glad you didn't cause a dead loop, you need to separate each loop into different time,like Update() . not in the same function .

[pale drift]

but if i put it in update, wouldnt they just start moving without me pressing the button to start the game

[signal yarrow]

set a variable like "pressed", set true when event trigger. if(pressed) do things . set false at last of Update()

[hollow folio]

Well as I don't normally code in C#...

It only gives me classes and not any objects though?

[signal yarrow]

find any audiosource object

in scene

[hollow folio]

Ahh, ok.

[signal yarrow]

it's still painful to code even as a unity programmer like me.. Because I cannot coding freely, limitation is very painful.

[hollow folio]

How would I reference "this" as in the gameobject this is running on?

[signal yarrow]

I don't understand what you're saying

[hollow folio]

This script is going to be attached to a gameobject. How do I get/reference that gameobject?

[signal yarrow]

just .. "gameObject"

it's in there

what else ?

[hollow folio]

Oh, so that will be this gameobject by default?

[signal yarrow]

yes, as well as "transform"

sometimes I do think Udon system is above most of people's knowledge level. and they even never mentioned about to learning C#+Unity game coding

[hollow folio]

I do full stack dev work, but not in C/# so it's still mostly alien in how it's supposed to work, even if the basic principals of coding are still the same.

[flat anchor]

Hey, I am trying to reset a Pickup Gameobject to reset to its original position OnDrop, how would I do that (would I use VRCObjectSync's Respawn, if so how)?

[strong arch]

whats the problem

[sleek sorrel]

You're missing a semicolon

[strong arch]

im a bit stupid

[sleek sorrel]

You could just store the initial transform in start and move it back when you're done, but checking the docs respawn does just move it back the original location

[sleek sorrel]

Line 9 no semicolon

[flat anchor]

I think I ll make it more adjustable and add another public transform for the reset location (Start/OnDrop), thanks for the help

[strong arch]

thanks

got other errors

this is the code

[sleek sorrel]

You misspelled player in trigger enter

[strong arch]

i saw it but thanks anyways!!

[strong arch]

it want work

[junior vine]

Can anyone explain this behavior? The bubbles don't work properly in the beginning, but fix themselves after a few attempts. The colors don't always sync up for other players as well.

The red and green buttons just set the player's tag to "it" and "not it."

[pale drift]

im not sure if its different for udon, but can parent objects handle collisions of the children in the parent script?

[vapid bough]

anyone know why Im getting this error?

[autumn topaz]

dont know that language

[vapid bough]

Im using the beta Vrc companion app

just converted my world and its telling me that

[indigo finch]

normally, when it only works after a while, it's usually because something isn't getting setup right on start but redundancies in your code correct the mistake after a few interactions. I would look into how your defining who is 'it'.
Another thing to watch out for, is that onPlayerTriggerEnter gets called whenever a player enters a collider, regardless of if it's the local player or not. I would grab it's playerApi, and put it through a playerApi, get islocal check, otherwise everyone will be playing the event and sending networked events

[indigo finch]

that might work for the first, but it's better to check if they are the owner

[junior vine]

You were totally right, I managed to get it working thanks to your suggestion. Thank you!!

[pale drift]

is there anything specific i need to do to be able to use objects from other class files? I am trying to make horse racing and i tried just having one script and i couldnt, so its going to have to be multiple scripts. When i tried earlier to access a external script using namespace, i couldnt

[signal yarrow]

public OtherType variable . or get target gameobject and gameobject.GetComponent<OtherType>()

[gilded jay]

So I'm not much of a computer guy I know how to retexture and upload avatars but the scripts for the sdk have completely have errors and I idk how to fix it

On unity

[signal yarrow]

Is there any Type that similar to List<>? because List<> or ArrayList are not available in Udon

[gilded jay]

I'll see

[bright elk]

What’s udon

[gilded jay]

Assembly assets/VRCSDK/Plug-ins dynamics.PHYSBones.dil will not load unity mathematics
Dynamics. Contact
Unity burst
Vrc collections unity burst
dynamics.PHYSBones.editor.dil
Dynamic Contact editor will not load

Oh and c sharp. Editor

That was after

[strong arch]

i don't understand whats wrong

[wind atlas]

You'd use a regular array, custom data types like that are not available.

[wind atlas]

Try reimporting the correct SDK.

[wind atlas]

I've seen some people implement them into an udon behavior, but not sure how efficient they are.

[signal yarrow]

that makes me struggled with dynamic length array. see if there is any way to do that

[wind atlas]

You can create a new array with one more space and then Array.Copy or whatever the method was from one to the other.

[gilded jay]

i did and it still errors and this started happening after may 31 update

[signal yarrow]

of course I can make custom array functions , but that not efficient

[wind atlas]

Well yeah, you pretty much always trade off convenience for performance. I'd honestly just use Array.Copy into a new array and not think about it as much unless I really have to.

[wind atlas]

I have not tried the new update then

[wind atlas]

Your path is also weird. Usually there is no "SDK3A" folder when you import the world SDK.

Might be the new update, but I'd really make sure you are importing the right one.

[signal yarrow]

i have that problem too when i imported both world and avatar. turns out to fully delete avatar sdk

can we launch 2 test client with different player name ? because I can't tell players who is master or client

[gilded jay]

let me see because i downlaoded the new sdk from the vrchat website on downloads from the profile stuff

and its not the world sdk its the avatar sdk

im trying to upload avatars

and thats what i downloaded was the 6/03/2022 avatar sdk

this is the right sdk right?

its the one im using

[wind atlas]

This is the udon channel, which is based on the world sdk. You could try the avatar channels, maybe someone will recognize what's happening instantly.
Either way, to me it looks like there are either missing files or some kind of issue when compiling.
I'd recommend creation a new project entirely and doing everything step by step according to the documentation. Make sure you have the right unity version and stuff like that.

[slate orchid]

how do i do an udon behavior it slows the player till they get off the collider of the object

[gilded jay]

um where do i go for avatar sdks

[wind atlas]

It would help if you could post what you are expecting to happen vs what happens.

[wind atlas]

Like the avatars-3-help channel?

[gilded jay]

thank u

[slate orchid]

so when a player mesh collides with the ground i want it to slow them down

[wind atlas]

Do you want to just decrease the movement speed? Then you can use one of these:

[slate orchid]

wym sorry

[wind atlas]

Those methods allow you to control the player speed. Is that not what you want?

[slate orchid]

yeah just when i am on a certain mesh

like if a player runs in mud it slows them down

[wind atlas]

Well, that depends on how your "mud" looks like. For example, if you want to define trigger zones on the floor, then you could use OnPlayerTriggerEnter to set the speed and OnPlayerTriggerExit to reset it back. Maybe this will be helpful: https://docs.vrchat.com/docs/player-collisions

[slate orchid]

@wind atlas so something like this?

[wind atlas]

Close but not quiet. The left part with the trigger is wrong. What this does is: it only trigger when your "Quad" enters the object this script is on.

You need the specific player trigger events I posted in the link before.

You could also go to the VRChat Examples and open the scene there. It has some examples, including some scripts to detect when a player enters an area.

[slate orchid]

I got it working thanks

[lament valve]

Is there a way to grab a player's account creation date through Udon?

[neat quail]

Now I'm having a really strange issue, has anyone else had a bug where a pickup spins in the player's hand when it's held by someone that isn't the instance owner?
edit: of course i just restarted all the instances of vrchat i had running and the issue went away

[coarse parrot]

There isn't a way to identify player data from udon other than player display name.

[viral fjord]

When I change my skybox ingame, the reflections don't update with it (the night screenshot on the left still has the reflection colors from the day screenshot on the right). Is there a RenderSettings node that can update this?

[dull mountain]

hello! I'm new to using Udon, and I found something called UdonSharp. I made an AI script designed for a horror game I'm working on for VRChat. I'm not all that familiar with the way Udon does things, and I have this compile error that I don't quite understand. I'm hoping someone here could help me out. Udon doesn't seem to like this specific line of code

[dull mountain]

ookay, well the error slightly changed after using the official version of UdonSharp. It's more specific, but doesn't tell me what I should use instead "Method is not exposed to Udon: 'GameObject.FindGameObjectWithTag("Player")'"

[grand temple]

Tags in general are not exposed to udon because tags cannot be uploaded with worlds. if you really need to find an arbitrary gameobject you can use Gameobject.Find, to find by name.

However, that's not really the answer that you need. The real answer is that

A) if you want some arbitrary gameobject, you should keep a reference to it from the beginning and store it as a variable somewhere. Maybe use Gameobject.Find once on start if you really need to. It's a huge waste of time to go searching for objects every frame

B) You probably don't want a reference to a gameobject at all anyway, since you're looking for a player. Players in VRChat are not referenced as gameobjects, they are referenced as a VRCPlayerAPI. If all you need is the local player you can simply do Networking.LocalPlayer and then once you have that you can do various things like GetPosition or GetTrackingData.

[dull mountain]

that just gave me more errors :/

I should probably mention that I'm not that smart when it comes to C#, but unfortunately it's the only way I can think of that'll give me what I need for the AI

I tried deleting the entire code for the AI to chase the player upon spotting them, and that got rid of the errors. But I kinda need the AI to chase the player, since it's supposed to be a horror game heh

I know I'm definitely doing something very wrong, since C# is extremely picky on where certain lines should go. But like I said, I'm not smart when it comes to C# scripting

I learned how to make this AI script from youtube, and doing some testing it's exactly what I'm looking for. The AI will wander between set nodes, and will only chase the player if it spots them in plain sight. if the player is behind walls it will not chase, but only if it sees the player will it start chasing

I've tried searching for similar Udon scripts, and even tried seeing if anyone else has some kind of tutorial for this kind of AI. But it seems like not many people makes this kind of advanced AI for vrchat

[scarlet lake]

Particularly the EnemyController and state scripts (i.e. ChaseState)

[dull mountain]

alrighty, will do!

thanks

[scarlet lake]

Np, please save the links though cause I’m gonna delete them

[dull mountain]

alright, done it

[grand temple]

I think the biggest thing that you're doing wrong is not using Visual Studio code. C# is one of the best languages for autocomplete and code assistance, so it's very important for the learning process to make sure that your editor is properly connected to unity so that it can point out errors visually before you ever get to compiling

https://code.visualstudio.com/docs/other/unity

there are other ones like jetbrains rider or visual studio community and they have minor differences, but code is the "most free" and easiest to get your hands on. It's important to at least get something

once you get that set up, you should be able to see much more clear errors, like the fact that playerapi's don't have a transform, should just be highlighted red the moment you try to type it. And instead when you start typing position it will present you with the correct thing instead of having to just hope that you've typed it correctly

[torn nest]

are destroy and instantiate calls bad for vrchat? im working on a world that requires dynamic spawning and destroying

[unborn hornet]

Use VRCInstantiate

[junior vine]

Is there a way to send an event to all udon behaviors that are using the same udon graph?

[pale drift]

is there something similar to "goto Label" cuz i need to jump to a different spot in code and labels arent supported

[grand temple]

technically JUMP exists in assembly but I really hope you're not writing raw assembly. If you're using udongraph then you can make a custom event and sendcustomevent, and if you're using udonsharp then you can make a function and call that function like any regular C#

[pale drift]

no im using UdonSharp

[grand temple]

that kind of question does confuse me though because it could either be coming from someone who has no idea what they're talking about or someone who really really knows what they're talking about, so apologies if that's not helpful. Would appreciate some context of where you're at

[pale drift]

        {
            
                mover = Random.Range(1, 4);
                distance = Random.Range(-0.1f, -0.4f);

                if(horseYCollide == true && horseRCollide && true && horseGCollide == true && horseBCollide == true){
                    end = true;
                }else {
                    if (mover == 1)
                    {
                        if(horseYCollide == false){
                            targetY = new Vector3(horseY.transform.localPosition.x + distance, horseY.transform.localPosition.y, horseY.transform.localPosition.z);
                        } else if(horseYCollide == true && end == false){
                            goto Finished;
                        }else{

                        }
                
                    }
                    else{

                    }

so for context, i have a working horse racing game. 4 horses (so code continues in similar fashion for results 2,3,4) right now im trying to make it so that when 1 horse crosses the line, it jumps back to beginning of MoveHorse

reason i cant just let it finish is because this is at the end of MoveHorse SendCustomEventDelayedSeconds(nameof(MoveHorses), 4f);

[grand temple]

if you're just looking for more control over flow in C#, then I would recommend learning about things like return, continue, and break. They're generally designed to be safer than a raw goto. In that situation you'd probably want to do

return;``` if you want nothing else to happen

[tepid salmon]

@scarlet lake you forgot to add the mirror it say self so the button.btw i dont mean on the udon graph i mean on the button where the script is the field where the mirror should be is empty

[tawdry minnow]

Why when I download USharpvideo player and use it. It show me that the script is missing

[grand temple]

do you have udonsharp and the vrcsdk installed?

[tawdry minnow]

I use it another project and yes I already install both

[grand temple]

but do you have it installed in this project?

each one is independent

[tawdry minnow]

I forgot in this project

but nvm I just doing the videoplayer by myself and it work now

[tawdry minnow]

I will try to tysm

[indigo finch]

Just need to drag and drop:

[signal yarrow]

what is "sendChange" compares in Udon Sharp? how to do it?

[grand temple]

The equivalent in udonsharp is to always work with the property, not the backing variable

[signal yarrow]

do you mean the property and variable combo that used for FieldChangeCallback?

[grand temple]

yeah

[signal yarrow]

local multiple clients that launched by Unity can be synced properly. But online world with real players sync is different. I'm getting huge struggled with it. 😭

it seems solved ! thanks

[iron vault]

Heyo, I'm trying to get a change_material_on_event scritpt to change the material on multiple objects, how would I go about that? i've figured out the whole material index, but how would I go about making it change the material on multiple?

it's just the default example script, but it works for what I need, I think

[indigo finch]

you would want to make an array of all your meshrenderer's and whenever you go to change the material, you just need to cycle through each object in the array: https://youtu.be/s3mZ7SLfmzI

.
Quick question, is there a way to cancel delayed events? turning on and off the object doesn't seem to do it...

[oak marten]

Hey guys, does anyone know if it is possible to allow players to adjust the far clipping plane locally with a Udon setup? I can see there are nodes for it, but I can't quite figure out how to get it to reference the camera of the player.

[vapid bough]

Has anyone used the Feature AttachToMe ? Its causing me errors but was working earlier so idk whats going on

[dull mountain]

well that helped! But not completely. I managed to get the compile errors to stop, but now I'm facing a new issue

happens every time I get near the AI

[signal yarrow]

can I invoke any method with out knowing target class? just like reflection. Because usharp could do that any way. but how?

with params and return value

[verbal tendon]

guys, i need people that can help me with a youtube video im making in VR, what would be the correct channel to use to find them?

[mighty fjord]

Seems like you're trying to get the actual player Transform, is that right?

[dull mountain]

yes, thats right

[mighty fjord]

It's not supposed to be possible to get behaviours which are not part of your world, so udon will return null if you're trying to meddle with something outside of its scope, e.g. player objects

[dull mountain]

thats gonna be a problem. the script needs to detect if the player is nearby

[mighty fjord]

PhysicsOverlaps will populate an areay, but the elements in it will be null if they're protected

What you want to get instead is probably VRCPlayerApis, which have the location of the player exposed

You could probably have a trigger collider on the same object and use the OnPlayerTriggerEnter event to get all VRCPlayerApis at a given location

[dull mountain]

I'd have to re-write things that I don't quite understand. I swear this would be way more simple if I could just commission someone to write me the script I'm looking for...

only problem is, I have no clue who I could even pay. So I'm just having to figure it out myself

stressful stuff

[vapid bough]

help

[indigo finch]

it appears you have an error with 4 or more udon scripts

[pale drift]

im a little confused. Getting error NullReferenceException: Object reference not set to an instance of an object HorseSpace.horseRace.Reset () on line resultsArray[0] = "";

and then this has just had a few different issues so im thinking im not even going about this the right way

    {
       

        GameObject firstPlace;
        GameObject secondPlace;
        GameObject thirdPlace;
        GameObject fourthPlace;

        public horseRace race;

        void Start(){
            firstPlace = GameObject.Find("FirstPlace");
            secondPlace = GameObject.Find("SecondPlace");
            thirdPlace = GameObject.Find("ThirdPlace");
            fourthPlace = GameObject.Find("FourthPlace");

            
        }

        void Update(){
            firstPlace.GetComponent<TextMeshPro>().text = race.resultsArray[0].ToString();
            secondPlace.GetComponent<TextMeshPro>().text = race.resultsArray[1].ToString();
            thirdPlace.GetComponent<TextMeshPro>().text = race.resultsArray[2].ToString();
            fourthPlace.GetComponent<TextMeshPro>().text = race.resultsArray[3].ToString();
        }
    }```

basically my goal is to update a canvas with TMPro's on it for 1st, 2nd, 3rd, and 4th as they cross the finish line

i get this error on the resultsHorse class ```VRChat client runtime Udon exception detected!
An exception occurred during EXTERN to 'SystemStringArray.__Get__SystemInt32__SystemString'.

[flint oriole]

Hey good rule of thumb may be to null check some of these references to narrow it down

[wind atlas]

First of all, don't use GetComponent in the Update loop if you care about FPS.
The first error is a bit confusing. If I take it at face value, then you haven't set "horseRace", which doesn't have much to do with the line you posted.
For the second error, I'd be curious what type "resultsArray" even is.

[wind atlas]

Posting the full error log would be helpful.
Also, the second error could also be, because you don't initialize the array at all, but I'd need to see more about the error and your code.

[wind atlas]

And since you are asking about what kind of approach to take: I'd create a method "FinishRace(result)" and do something like this:

index += 1;
resultTextArray[index].text = result.ToString();

"resultTextArray" basically holds all of your TMPro references and you just go from the first to the last one and assign whatever result you want to them with each "FinishRace" call.

This way, you also avoid the Update loop.

[vapid bough]

Anyone use the attachtome system? In USharp 1.0 beta, its not wanting to work for me. It keeps breaking when I hit play.

[signal yarrow]

can we start 2 Unity Editor to join together? or one VRChat client + 1 Unity Editor.

[pale drift]

Well so i have to do an update loop anyway for the MoveForwards i have to move the horses because that was the only way to get smooth movement that i could get working. I did get the TMPs working through the update, so will it really be that much of an fps killer?

If so then ill try to make a method for it then. Last time i tried though i couldnt get the tmps to update at the right time, they were always late to updating the text

[topaz jetty]

nope

[wind atlas]

The issue is mainly the get component calls inside the update loop. You should at the very least cache it at Start. So instead of just saving the gamaobject, save it as a TMPro object directly.

[pale drift]

Oh ok i think i get what you mean. Im not home so i cant look and im a very beginner coder (only have taken a beginner java and beginner C++ class so far). Thank you for explaining it all though. So just to make sure i understand, i should create a TMPro object, cache it in the start, then in update, just update the text?

[wind atlas]

Yep, you got that right. This is more of a unity than a language thing. GetComponent calls are not free, especially since udon is slow. Your script by itself is probably fine, but if you keep doing things like that, it will become noticeable.

[pale drift]

Ok ill try it out later then, again thank you for your help

[brittle torrent]

currently having an issue with a null reference exception, and i have no idea how to solve it this time

based on the log, i believe the issue is coming from the eventName being passed to sendCustomEvent

      Parameter Addresses: 0x00000026, 0x00000027
  
  Object reference not set to an instance of an object```

what i've done is named this game object's name, custom event and UdonBehavior all the same, that way my code can just pull the game object out of an array, get its attached udon behavior, and then look at its name to know what customEvent it should call

but, for whatever reason, Udon is not liking that Get name node

i already set up some logs to spit out what Get name "gets," and it isn't null

any and all ideas would be appreciated

[wind atlas]

That error means that whatever object you are calling "SendCustomEvent" on is null. So whatever you are getting with GetComponent returns nothing.

[brittle torrent]

i see

[wind atlas]

GetComponent always confuses me in udon graph so I'm not sure what's wrong with it.

But it seems like using whatever string you are using doesn't get the correct udon behavior.

[brittle torrent]

well this was part of a workaround due to UdonBehavior[] being broken

nothing better than having to workaround your workaround

thank you though

holy shit

found out why it was pulling null (probably)

it's because i spelled the type as "UdonBehavior" and not "UdonBehaviour"

all because i don't adhere to the STUPID British spelling conventions

that fixed it

[shut ermine]

this would be nice by the way

still looking for one

[humble bolt]

I tried importing the OSC prefab into my world and I got this any ideas on fixes?

[storm kettle]

i’m getting this error. can anybody help me fix?

[indigo finch]

open up the console and have a look at what error messages there are (btw, windows key + shift + s is an easy way to screenshot only part of a screen)

[ebon dragon]

any idea how to have an instance directly face the player? this doesn't seem to be working just right, it does move though ~

it's like it takes the center of the world instead of the head pivot position

[ebon dragon]

update: fixed it

[pallid roost]

Anyone know what would cause this error?
Everything was working fine and then it just randomly started when i changed scene and back.
Ive tried everything from deleting the vrcsdk and reimporting, all the other dependant packages, reimport all.
Everything short of just recreating the project.

[brazen epoch]

there is nothing like this

[scarlet lake]

how to do conditions in udon behavior script?

[brittle torrent]

as in making an if statement?

you have to use a Branch node

[scarlet lake]

yes

okay and how do i check if an Animation is toggled or not? for example if i want to make an door that can only be opened manually but it closes automatically

[brittle torrent]

that sounds like something animation conditions would handle

[signal yarrow]

can I Instantiate unlimited amount of pickupable+synced gameobject? rather than using pool because that's limited amount

[brazen epoch]

Pretty sure you cannot instantiate synced objects

If you need more, just create a larger pool. If you need close to Infinity, then you might be doing something wrong

[signal yarrow]

ok

[brazen epoch]

VRC_Pickup.currentlyHeldBy is defined as a component, but what is it actually?

[signal yarrow]

just try to Log that

[brazen epoch]

💀 Since it's defined as a generic value by which a lot is extended from, one can assume that it can be multiple things, so knowing the possibilities is helpful and can eliminate unexpected behavior during runtime

most developers are lazy and don't test everything

[wind atlas]

Oh yeah, that one field is weird. I don't feel like it should be a component, as the only thing we actually get from a player is VRCPlayerAPI, everything else is blocked.

So what even is that? Can you try printing the name of it or something?

[hollow folio]

Is it possible for scripts to share variables? e.g. for there to be "global" variables within your scene that any script can just access at any time?

[brazen epoch]

yes. If you're using the udon graph, there's a method on UdonBehaviour that allows you to get public variables. I forget the name. If you're using Udon#, then it's just like any regular script

[hollow folio]

Ah cool, thanks.

[brazen epoch]

nvm. currentlyHeldBy is not exposed to Udon

[hollow folio]

Hmm, setting default values is easy for UdonSharp scripts, but how do you do it on the node graph?

[strong arch]

is it posible to make a "wait for seconds" with udon (no code)

[grand temple]

yes, sendcustomeventdelayed

[strong arch]

thanks

[grave lantern]

Do anyone know if it's possible to change the camera lense type in udon?

[dull mountain]

anyone got a foostep script I can use?

[slim jacinth]

Is there a way to stop a player from pushing a rigidbody? But still able to stand on it?

is it a matter of making it kinematic?

Ideally I'd avoid that

[ebon dragon]

this is exactly what the kinematic checkmark is for afaik

[fathom furnace]

Strangely I can't seem to find any information on how to simply check if a player is currently pulling their controller's trigger or pushing a button on it 😆, does anyone know how to do this?

[fathom furnace]

Found it, see message being replied to for an example. For anyone trying to check if the player is currently pulling their controller's trigger (or left clicking their mouse), here is how you do it:

    public override void InputUse(bool on, VRC.Udon.Common.UdonInputEventArgs args)
    {
        if (args.eventType == VRC.Udon.Common.UdonInputEventType.AXIS)
        {
            return;
        }
        if (on)
        {
            // Do the thing
        }
        else
        {
            // Stop the thing
        }
    }

[brazen epoch]

You can have an area trigger and have a list of pickups that should stay in that trigger and OnTriggerExit if a gameObject is in that list, then Drop it and teleport it back

[unborn hornet]

Or be even cheekier: if the player is holding the pickup, force teleport them back into the area relative to the position of the object such that the object is retained within the area. Result is that it feels like the object cannot be physically taken out of the area. I've seen a couple worlds do this. (This is a bit more complex though)

[indigo finch]

or have an invisible pickup, that tells the visual (non interactable) pickup to move to the same location, but checks to make sure it's still in the collider. Then you can stop it from leaving, while also the player can keep walking around outside the barrier, and you don't drop the object (also a bit more complex)

[tacit harness]

Hey , im using udon graph

Im trying to convert a float value to a "mm : ss" format
Does anyone know how to do this ?

Please ping or dm me if you know

[upbeat rose]

FindObjectOfType does not work and I don't want to use a name-based function or parent base function. Any alternatives to this function?

[pale drift]

what would be the best way to keep a player from rapidly interacting with a button? I have a button for a game with the normal Interact() method, but i want to avoid accidental double clicks, so what is the best way to have like a small delay after the button is pressed before they can press it again

[vapid bough]

Wonder if anyone can help me? I have a gun system in place but when people use the second grip (Like a forward grip), it isn't synced on the other players end. Meaning on your end, you are aiming at them, but visually on the other person end, they are not. It doesn't effect damage or anything, just makes the visuals look wonky.

[wind atlas]

You can use basic math to get that format. For seconds, you can divide it by 60 to get the minutes etc

[wind atlas]

Can't you just use getcomponent or create a reference that you can assign in the inspector?

[wind atlas]

A delay between one player spamming or a delay between multiple players spamming it? If it's just one player, then create a bool isBlocked and set it to true on Interact. Also do a SendCustomEventDelayed to a method that sets isBlocked to false.

[upbeat rose]

Here is a 1 second cool down script

float TimerTemp = 0;
float TimerMax = 1;

void Update()
{
  if(TimerTemp >= 0)TimerTemp -= Time.deltaTime;
}
void Interact()
{
if(TimerTemp < 0)
{
 DoThing();
TimerTemp = TimerMax ;
}

}
public void DoThing()
{
Debug.Log("Boop");
}

[upbeat rose]

I want it to not need a ref to a gameobject or use an inspector drag n drop. That is the easy way, I want to know the actual way without needing to do everything manually

[wind atlas]

You can reference your MusicBox type directly in the editor though, not just the game object. Otherwise the only solution I know of is to use GameObject.Find.

[tacit harness]

The problem beeing is that , lets say i have a float of 100
and then divide by 60 , it would display 1,6
Which is obviously not 1 minute 40 seconds

[upbeat rose]

use modular oporator? % and then floor the output?

Thats what I did for my library world with time stamps

[wind atlas]

Yeah, you only get the minute from that, which you can use to calculate the seconds.

Yeah, there are different ways to do it. For example, you can do:

var timeText = (time / 60) + ":" + (time % 60).ToString("00");

time is an int btw, that's why it works. So you could cast it yourself if it's a float: (int)(time / 60f)

[wind atlas]

That heavily depends on the gun system that you are using btw I'm guessing it just doesn't support that?

[vapid bough]

I guess so? Its just acting wack with the for grip

trying to make the for grip also synced, if I put vrc Sync on it, it makes the gun jitter

[wind atlas]

Try setting the owner of the grip on picking up the gun.

It really depends on the actual code of the gun though.

[flat musk]

It needs to first the on the default layer

[silver atlas]

Are there existing implementations of coherent noise? (Simplex, Perlin, etc)

[lapis rampart]

Does anybody know how I might go about toggling colliders with an interact script instead of a UI script?

[rugged sphinx]

Does OnPlayerTriggerEnter not trigger for child colliders like OnTriggerEnter normally would?

[whole rain]

It'd depend on how you're specifically using it, but realistically you should be able to just change the input from a btn press to on interact, assuming you'd be putting the script on the object you want to interact with.

[grand temple]

I'm pretty sure onplayertriggerenter should trigger in all the same conditions. Are you sure you have a rigidbody on the parent object, and is on the same object as the udonbehaviour?

[rugged sphinx]

Currently have a rbody on each collider. Think that may be the issue now that you mention it. 🤦‍♂️

hmm. nope, that didnt fix it

[grand temple]

that was extremely fast.... how are you testing?

[rugged sphinx]

I'm running this in editor right now too. Is that maybe it? I know its finicky

Client Sim

[grand temple]

did you go out of and back into play mode?

[rugged sphinx]

yup yup

[grand temple]

Well it is possible for clientsim to differ, you should try in client at least once

[rugged sphinx]

will do and report back

damn. No dice

[grand temple]

do you still have a rigidbody on the child objects?

[rugged sphinx]

i moved the rigidbody to the parent thats supposed to recieve the events

[grand temple]

and just to rule out the obvious stuff, these colliders are set to trigger?

[rugged sphinx]

np, correct

[grand temple]

and they're on a layer that collides with playerlocal?

[rugged sphinx]

I tried both Default and MirrorReflection layers yup

[grand temple]

idk, could you share some pics of how it's set up?

[rugged sphinx]

Sure thing

parent

child ^

I've got debug logs in the scripts OnPlayerTriggerEnter overrides

I am using U# if that matters, not graph

[grand temple]

try adding ontriggerenter debug log and throw something at it, see if it detects that

[rugged sphinx]

it triggered the log for OnTriggerEnter. Object didnt have a name though

[grand temple]

whaaat

[grand temple]

onplayertriggerenter literally comes from ontriggerenter

[rugged sphinx]

That's what I figured

[grand temple]

are you sure that the script isn't crashing or something?

[rugged sphinx]

no errors in the console. no errors on the script

the debug log for OnPlayerTriggerEnter is the very first thing

and all I'm doing is incrementing and decrementing an int if the player is valid and is local

I'm currently on U# 1.0.1

[grand temple]

ok what happens if you put a collider on the same object as the udonbehaviour

[lapis rampart]

wait was there not a concrete answer and now y'all are doing testing?

[rugged sphinx]

lol, the OnTriggerEnter still fires, but no dice with the OnPlayerTriggerEntered

ill try building

😔 nope

[grand temple]

do you have another rigidbody that is a parent of this?

[rugged sphinx]

Nope, just a Gameobject used for organization

No components on it
