[coarse parrot]

The layer is blank

[visual gale]

yeah idk what it is

but somehow its working when its blank??

[coarse parrot]

Could you click on it and show layer number?

[visual gale]

?!

[coarse parrot]

I'd guess the blank one is on layer 22

[visual gale]

so how would i get it lol

[coarse parrot]

Add Layer

[visual gale]

the hidden layers

lol

[coarse parrot]

The layer name is arbitrary so it can be anything.

But name it PostProcessing

For layer 22

See if it show up in the sleep mode object

[visual gale]

Working!

Thank You!

Also one more question

@coarse parrot do you know if there is a way to easily transfer the sdk2 pedestals to sdk3 bc there are missing scripts or do I have to manually make them sdk3 peds

[coarse parrot]

I haven't work is pedestals yet. I couldn't answer that question.

[visual gale]

alright no problem

thank you!

[visual gale]

do you think this is why it doesnt show up in scene?

[visual gale]

can I separate the capsule collider from the pedestal itself

[coarse parrot]

A collider is need for interaction for a game object though.

[scarlet lake]

anyone know why the world disappears while flying ?

things just become very hard to find because it gets unrendered or something

[dapper lion]

occlusion culling

[scarlet lake]

i dont think i even enabled it but ill check

where can i enable/disable it again?

[dapper lion]

occlusion window

[loud bridge]

How far away is it? Could be getting z-clipped by the camera.

[scarlet lake]

its basically a veryyy big platform to show where the ground is of the world

how can i stop z clipping?

[loud bridge]

You can't. In normal game dev, you can adjust the camera's clip settings, but I don't think those are exposed in VRChat. You'd just need to scale down and move closer.

[scarlet lake]

the problem is, its a flying world so scaling it down isnt really an option assuming you are talking about the world

[dapper lion]

you can change far distencs in main cam in vrcsdk

[coarse parrot]

You can set camera clipping for vrchat though

[loud bridge]

There you go. do that then ☝️

[dapper lion]

set near distance low as possible so peipke dont complain later

[loud bridge]

Yeah, but then you get ugly z-tearing.

[dapper lion]

when far away for 000

in a perfect scenerio. the space around would move to local space rather than world

[scarlet lake]

how can i do that?

this camera?

[coarse parrot]

That

[scarlet lake]

i just set it to reference camera in vr wold prefab

[coarse parrot]

And set reference camera in world desciptor to that camera

[scarlet lake]

and i pushed the far up and near

does camera placement matter?

[coarse parrot]

What camera placement?

[scarlet lake]

of the main camera

does it matter where it is

in the world

[dapper lion]

no

[coarse parrot]

So you meant location. Doesn't matter

[scarlet lake]

ok good

gonna run a quick test

[coarse parrot]

If you're too far from world origin, graphic will get messed up though.

[scarlet lake]

alright

and

how can i find the borders of the world?

[dapper lion]

wym

[coarse parrot]

There isn't. But further you go, more mess it will be.

[scarlet lake]

so when i am flying, i will randomly get kicked out of the plane once i reach a certain area

some directions are closer

some are further

they seem to be borders

[loud bridge]

Nah, z-tearing can still happen from the origin. Floating-point imprecision farther from the world's origin just exacerbates it.

[scarlet lake]

i notice in some flying worlds they have borders too

also the camera clipping is fixed

thank you guys for that

[dapper lion]

this isnt blender but ok

[loud bridge]

Basically, Unity/VRChat uses 4-byte floats for locations. The further you get from the origin, the bigger the numbers get, the lower their precision. That causes all kinds of weird issues. Borders are just one way to solve that.

[dapper lion]

32bit

[scarlet lake]

hmm alright what would you recommend is a good way to set up borders?

[loud bridge]

4byte=32bit

[dapper lion]

ihni heard someone call it 4 bytes before lol

[dapper lion]

depends how much land is being covered

[scarlet lake]

flying world so a lot

[dapper lion]

far away borders then

[scarlet lake]

im trying to think of how I will make the borders

[coarse parrot]

Better think how you'd like it to be

[scarlet lake]

maybe just giant walls with a glass like matieral

[dapper lion]

fog

[scarlet lake]

fog/

?

[loud bridge]

Just put the whole map under a big simpsons-esque dome.

[scarlet lake]

xd

[dapper lion]

proximity shader

[fossil moss]

Hope you don't mind the ping. But thanks a lot for sharing your footstep Udon! I've been trying to make one since around January myself but I couldn't (I'm just not experienced enough).
I've made a small addition to it by adding isplayergrounded so it doesn't play midair and to find if a gameobject is active to only play in a specific area.

I do have a question about this tho if anyone can answer. Is there any way I could possibly make it based on a player is walking on a mesh collider? Currently its based by a gameobj that is enabled through a box collider, very wacky.

[scarlet lake]

iv never done that before xd

[loud bridge]

You'd probably need to write your own IsPlayerGrounded routine so that you could capture the collider that they're grounded on.

[fossil moss]

I guess that isn't exactly happening then lol

[loud bridge]

You could also raycast downwards and just see what you get. May not always be properly accurate though.

[fossil moss]

I don't even know what that means, F

Seems like hellalotta more work

Thanks a lot for the suggestions nonetheless. I think this is a quite decent start for having footsteps, albeit a little cumbersome but works as intended

[full jetty]

Anyone know how I can make particles emit in each players hands?

[loud bridge]

Get the VRCPlayerApi, then in Update, get the hand's bone position and orientation and apply those to the particle system's transform.

[full jetty]

Hmm... how do I specify which particles go to which players?

[loud bridge]

Depends on how you want the activation to trigger.

[full jetty]

What do you mean?

[loud bridge]

As in, what causes the particles to be applied to their hands?

[full jetty]

Umm... lets say for testing purposes there are different colored particles and the player can choose which one they want by pressing a button?

[loud bridge]

Then when they interact with the button, you know which player to initialize the script for.

[full jetty]

Well... the thing is I'm very new to Udon. How do I say the person who pressed this button is the person who gets this color?

[loud bridge]

Depends on how the button is implemented.

But generally, when something is interacted with, the player who interacted with it is passed as an argument.

[coarse parrot]

Interacting can only happen in local client with local player though

Determining which remote player pressing the button is quiet tricky

[arctic scarab]

how i sync toggle in udonsharp

    public override void Interact() {
        GameObject test = GameObject.Find("Deck1");
        if(test.transform.childCount != 0f){
        Transform selection = test.transform.GetChild(Random.Range(0, test.transform.childCount));
        selection.parent = GameObject.Find("Deck1 active").transform;
        selection.gameObject.SetActive(true);
        }
    }```

[arctic scarab]

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;

public class deck1 : UdonSharpBehaviour
{
    void Start()
    {
        Debug.Log("start");
    }
    public override void Interact() {
        GameObject test = GameObject.Find("Deck1");
        if(test.transform.childCount != 0f){
        Transform selection = test.transform.GetChild(Random.Range(0, test.transform.childCount));
        SendCustomNetworkEvent(NetworkEventTarget.All, "Sync");
        }
    }
    public void Sync(){
        selection.parent = GameObject.Find("Deck1 active").transform;
        selection.gameObject.SetActive(true);        
    }
}

will that work

[floral dove]

You can learn the basics of networking here: https://docs.vrchat.com/docs/udon-networking#overview-how-networking-works-in-udon

[arctic scarab]

okay i just hold everything 10 million meters away

[pastel tiger]

hi. I'm trying to make a boss fight arena. All what I need to do is to make the player respawn when colliding with enemy projectiles. For some reason (mostly I don't understand how the respawn function works) the player doesn't respawn when colliding. Doesn't matter if I do it with udon graph or udon#. The collider is working fine and it's pushing the player backwards on contact.

these are the projectiles (blackholes looking balls)

[fossil moss]

Are these projectiles using a box collider? If so try enabling "is trigger"

[pastel tiger]

then changing it from onPlayerCollisionEnter to OnPlayerTriggerEnter?

[fossil moss]

i mean the projectiles themselves.

but yes try that as well

[pastel tiger]

didn't work

[fossil moss]

gimme a sec

wow this isn't as straightfoward as i thought it was

[pastel tiger]

yeah

[fossil moss]

I can show you an alternative if you wish

not as wholesome and straightfoward but this works

[pastel tiger]

what I'm thinking about now is

to teleport the player under the map

[fossil moss]

oh, then you can definitely use that

[pastel tiger]

thank you

[fossil moss]

you simply create an empty game object and place it where you want the player to respawn

[pastel tiger]

will try it now

not working🤣

the projectiles pushes the player backwards, but the collision even it not being called

[fossil moss]

eh?

[pastel tiger]

yeah mean. I have seen wonders with udon

[fossil moss]

the projectiles pushes the player backwards,

[pastel tiger]

because of the collider

[fossil moss]

Is the projectile itself supposed to teleport the player, or do you have some collider behind the level that will teleport the player?

[pastel tiger]

the projectile isn't set to be destroyed on collision

I just made a ball that's moving in a specific path. Set a teleport location under the map. While I move the player in front of the ball, the ball just pushes me back and the collision event doesn't trigger

so yes the projectile itself is supposed to teleport the player, as a way for the player to die while being hit/damaged

[fossil moss]

hmm... for a normal box collider w/ is trigger enabled, this should had worked perfectly fine, I built and tested.

I wonder if rigidbody makes things different, but shouldn't

[pastel tiger]

I will try it without a rigidbody

also it's a sphere collider but I think it should work almost the same as a box collider

[fossil moss]

yeah should be the same

Do 1:1 of the udon I did

or just copy this instead

[pastel tiger]

ok

lol everything works now

even the scripts that I coded but were not functional

I think they were not being updated

but once I imported your asset

I think all scripts got reimported

[fossil moss]

nice

[pastel tiger]

Thank you so much

been suffering with this for 3 days

[fossil moss]

winner moment

[pastel tiger]

you are my savior

[leaden granite]

Does anyone know if there's a way to access the local player's camera object in a script?

[indigo finch]

Pretty sure that's not exposed in udon. That being said, you can basically get it's position by using playerApi, get TrackingData, and set it to head

[leaden granite]

Oh, in that case, do you know if it's possible to get the distance between the eye cameras in VR?

I'm trying to create a fake window that shows a camera's view but also have it show up properly in VR

[indigo finch]

honestly, I would like to know that too... I think it might be more along the lines of shaders with dual pass, but I haven't really found anything

[leaden granite]

I saw a world (I think it was called Udon Portal World) that had functioning portals that worked in VR, no idea how they did it though

probably possible through shaders

[unborn hornet]

A snippet that I once saw and stashed. Never actually used it though, so not sure how well it works

var cameraScale = (headTracker.position - lastHeadTrackerPos).magnitude / (camera.localPosition - lastCameraLocalPos).magnitude; // Merlin's trick to get camera scale

[leaden granite]

oh cool

[unborn hornet]

Though tbh not sure what the camera variable represents beyond it being a Transform of some kind.

[leaden granite]

i'm really not sure what that's doing or what headTracker or that camera are pointing to

[unborn hornet]

headTracker = Networking.LocalPlayer.GetTrackingData(VRCPlayerApi.TrackingDataType.Head) basically.

camera is what I don't get. I need to poke the guy who I swiped this from to see if this is actually still valid code or not.

[unborn hornet]

Ah. Originates from https://github.com/MerlinVR/PlayspaceTracking here

[spark walrus]

if i run a function on Update() it gets called every frame and eats up performance? What if the object the script runs on is active at some time, does it still eat performance when inactive?

[fickle stirrup]

at least you can make a bool, and if it false do return; from update before doing any work it shouldn't eat much performance. don't know if udonbehaviour will still work on disabled object after enabling it
if it's Graph then just a Branch from bool and do everything if true

[spark walrus]

ok but does it still ask for the bool when disabled every frame?

[fickle stirrup]

yes but by itself it should not do any great impact on the performance

[grand temple]

functions can be called on a disabled script (as long as they've been enabled once before) but they will not receive any unity events like update

[spark walrus]

thanks

[spark walrus]

is there a way to lock the players movement when pressing Usedown on an Object?

[granite basalt]

immobelize on vrcplayerapi

https://docs.vrchat.com/docs/player-forces#immobilize

[spark walrus]

wow that was fast thank you so much ^^

[full jetty]

So I'm trying to make a world where players can have these particle orbs in their hands, but when I try to line it up with them and make the particles follow them there are some issues. The emitter doesn't actually rotate from where the bone is but rather from it's own center, so how can I make the particles sit in the players palm?

[bold marlin]

How exactly do you wanna do this?
As there are different ways to make a particle follow something (Example: locking to object with Parent Constraint, or pull it towards you with a Particle Forcefield)
It all depends on the style of particle you wanna use

[full jetty]

I actually figured it out. I just put it on a parent object and off set it a bit. Now when the parent object rotates so will the particle system, just on a different axis. But now I have a new issue... I'm trying to get the particles to be toggleable, but not traditionally. I'm trying to say if you interact with this object then the particles will start/stop looping (If I just turn them off they blink out of existence)

[bold marlin]

So you do not want them to just disappear instantly after the interacted with it?
Maybe make a script that stops the looping and then a timer to end the emission?

[full jetty]

I already have the way to stop the looping... and I guess a way to start the looping... just no way to do either depending on if it's currently looping or not

[bold marlin]

have a bool run with it to tell it if its looping or not?

[full jetty]

I don't know how to do that. I'm very new to Udon

[bold marlin]

your using graph or sharp?

[full jetty]

graph

[bold marlin]

@full jetty this is with a toggle bool with stopping a particle looping

[full jetty]

I'll try this now, thanks!

Where do I find whatever the Set LoopToggle is?

Nevermind, found it

[visual gale]

Anyone know how to fix this?

for clientsim

and a smaller issue my vrchat examples udon script is deleted and even when I reimport the sdk it doesnt fix it know what i could do?

[pallid roost]

Sounds like you need to import a missing post processing package in your package settings possibly

[visual gale]

where could I find that?

I have 999 errors about postprocessing???\

[indigo finch]

just checking, did you try and install the sdk along side the 3 different github urls from client sim?

[visual gale]

yes

[indigo finch]

one of those links is a vrchat sdk. It will give errors if you have your own installed as well. would start there

[visual gale]

I only have the official one installed?

I do see this

[indigo finch]

delete the one you manually installed. It will cause errors (I got 600 or so)

[visual gale]

idk which one that would be lol

[indigo finch]

the one you got from the vrchat website

[visual gale]

ok so just delete the folder???

[indigo finch]

folders. but yea

[visual gale]

yes

[indigo finch]

I couldn't get client sim to work with udon#

[visual gale]

udon#???

no

[indigo finch]

nevermind, doesn't seem like you have it

[visual gale]

it just says I need to fix compiler errors

postprocessing gives me 999

and spams my unity logs lol

UnityEngine.Rendering.PostProcessing.AmbientOcclusion.IsEnabledAndSupported (UnityEngine.Rendering.PostProcessing.PostProcessRenderContext context) (at Library/PackageCache/com.unity.postprocessing@3.1.1/PostProcessing/Runtime/Effects/AmbientOcclusion.cs:183)```

Found the solution, remove and readd the post process layer

new issue

[indigo finch]

pretty sure all of the errors are spanning from the two sdks trying to both work, with one not working because of the other. you will want to delete the folders udon, vrchat examples, VRCSDK.
Do a backup first though!

[indigo finch]

yea, that's the second sdk making noise

[visual gale]

oh its com vrchat base

as thats already included in the sdk

new issue

[indigo finch]

will it run at all?

[visual gale]

looks like its missing a directory

im going to try to reinstall it real quick

Assets\com.vrchat.ClientSim\Runtime\Helpers\ClientSimSpatialAudioHelper.cs(8,48): error CS0246: The type or namespace name 'ONSPAudioSource' could not be found (are you missing a using directive or an assembly reference?)

Anyone know what this is?

just reinstalled twice dunno why its doing this

[scarlet lake]

how do i stop hating udon so much

[visual gale]

lol

[visual gale]

I just need this fixed

lol

[lament valve]

What do these errors mean?

[arctic scarab]

what is script limits for setting positions

selection.position = new Vector3(0, 999999999, 0);

x and z being assigned but not y

[scarlet lake]

So I have an idea and I want to know if it's possible

Right now I have some effects that can be toggled on and off globally for everyone to see at my dj booth.

For optimization purposes I want to know if it is possible to make it so people can toggle off those effects locally and make it so the global trigger no longer effects them until they turn it back on

Is that possible?

[sonic burrow]

What does it mean when it says “(1 of 2)”

Does anyone know?

[scarlet lake]

By themselves

[sonic burrow]

Sometimes it says (5 of 20)

[obsidian stratus]

I'm currently working on a home map for someone should I avoid using sdk3? I've heard that if your home world is udon other worlds won't work properly

[slim hound]

This was a bug present around when Udon was first released and has been fixed as far as I know

[obsidian stratus]

The last time I saw someone run into this issue was last month I believe. I hope it's been fixed by now

[bleak magnet]

Anyone know if there is a plan for bringing back old object sync? The current one does not support animation syncing and is something i need to convert my other projects over that have already made animations.
currently was looking at this trigger system that was made to work with udon but i don't think it will work with syncing animations up to late joiners and the stuff i had help trying to figure out with just got more confusing and seems to be either alot more steps that should be needed or to abandon my animations and start over. thank you

[molten zealot]

So vrchat keeps giving the message “make sure your device has working internet connection’ message pls help

[fickle stirrup]

try to join with VPN enabled, if even with that it will not work, ask in #user-support-old

[elder peak]

sadly you need to make that yourself in udon
the old sync wasn't great either for animations

[bleak magnet]

i see the sync seems to be working great for me in my 2.0? had this world for over 3 years

[bleak magnet]

is there a way to do player teleport without interact by using something like on avatar hit? Or do I have to use on enter trigger ?

[fickle stirrup]

use this methods

[bleak magnet]

oo ok

stays local right?

[fickle stirrup]

after that you need to check if returned from method player.IsLocal (or player equals to Networking.LocalPlayer, both are doing the same)

[bleak magnet]

ya just needs to be local its a player reset area to reset the map when you respawn

[gleaming sage]

How would one go about using udon (graph if possible) to play an animation, or attach an animation to a slider? (eg. controlling brightness in a world)

[scarlet lake]

Show I’m looking to Optimize my world even more than it is already to get give more fps any tips

[verbal socket]

Question does anybody here take udon coding comissions ?
I want to make a small game in a world i got. I cant code it myself ive tried XD

[wind atlas]

I have a weird issue where players can run around and do stuff while they are stuck at the spawn for everyone else. No idea when it happens, and why, and I personally have never seen it except other people showing it to me.
They seem to be moving a little bit, and you can hear their voices.

[scarlet lake]

also does anyone know where to get good looking tents at?

like camping

[dapper lion]

do you have stations/chairs in your world? there was a time period where stations would get people stuck and if you reloaded the world the player was stuck in. theyd get stuck in spawn for others

[bleak magnet]

how would i hook up a teleport spot to this? not using interact so no field to drop my empty to

using on enter triggers

[bleak magnet]

figured it out had to drag the transform part in the object and not the object itself from my list

how would i make this local only and not global ?

[topaz jetty]

I think you need to install those packages in a new unity project, not in one that already has the sdk in there

[wind atlas]

Unfortunately, there are no chairs. Could avatars having chairs cause such an issue?

[full jetty]

Does anyone know how to toggle particle looping on and off with udon?

[wind atlas]

Do you know how to make a ParticleSystem reference? You can access that and change main > loop.

[full jetty]

I'm able to turn it off, and theoretically turn it on, but not toggle them

[wind atlas]

Create a variable of type ParticleSystem. Drag a node out of it and search for "main". Then drag a node out of that and search "loop".

This is how it will look like

[full jetty]

How do I get it to toggle the looping though?

[uncut tusk]

uhm is anyone here and can halp me? i have stil a problem with Videoplayer to use a Reverbzone qwq

[wind atlas]

Do you want to just toggle on and off a particle?

Or is the looping important?

If the looping is important you can do this:

[full jetty]

The looping is important yeah

It's the only way I can think of that won't just blink the particles out of existence when they turn off

Alright, I'll try this out. Thanks!

[wind atlas]

Np, looping might work with that. If not, you might want to look into stopping the particle system manually.

[verbal socket]

Toggle the particles by their emission tab not the emitter itself that keeps the ones it emitted going till their dead

But stops new ones from.emitting

[full jetty]

So... it turns them off but not back on again... how do I fix that?

[arctic scarab]

how i turn local function to function that syncs for everyone

[scarlet lake]

So I have an idea and I want to know if it's possible

Right now I have some effects that can be toggled on and off globally for everyone to see at my dj booth.

For optimization purposes I want to know if it is possible to make it so people can toggle off those effects locally and make it so the global trigger no longer effects them until they turn it back on

Is that possible?
(resent)

[wind atlas]

You could try the methods "Play" and "Stop then. Alternatively, you can access the rate over time and set it to 0 (what the person before suggested).

[bleak magnet]

i got my teleport to be local . is there a way to make my set active go local? the on player enter trigger is making it global still

[wind atlas]

Check if the player is local before you teleport.

[bleak magnet]

how?

[wind atlas]

The reason it's "global" is that you see every player move on your client. So other players can move into the trigger on your screen basically.

player > islocal

[bleak magnet]

the player is local at teleporting but the rooms are still global

[wind atlas]

and then plug that result into a branch.

[bleak magnet]

i need the node between the teleport to and my block to convert the global back to local if possible

my teleport is working fine

[wind atlas]

Take the player you get from OnPlayerTriggerEnter and the search for "isLocal". Plug that result into a branch before or after the TeleportTo, it doesn't matter in this case. I'd recommend putting the branch before the teleport because it can be called on a local player anyway and will otherwise be ignored.

[full jetty]

Uhh... yeah I have no idea what to do about the particles... I'm very new to Udon

[bleak magnet]

do i plug in the player api to the branch ?

[bleak magnet]

will this work to make everything local ?

[wind atlas]

Yes, only if they local player enters the area will the rest of the code get triggered.

[bleak magnet]

so only the 1 that enters will tp and set objects active ?

ty going to test with alt

[bleak magnet]

teleport broke can't trigger the set up when i run inside the colider

[full jetty]

I figured out the particle stuff!

[wind atlas]

Your TeleportTo needs the player instance plugged in.

[bleak magnet]

from my get is local ?

[wind atlas]

Probably can just use the player from OnPlayerTriggerEnter.

TeleportTo will crash if it's missing the player in general. Same with all other nodes that require all the inputs.

[bleak magnet]

aw i see ty

i will try again

[bleak magnet]

should the branch be true or false? trying to make the object active also local and active with the tp

i have to use false which only makes the tp local and not the set actives

could i use exit trigger for after player teleports it does the object actives?

[wind atlas]

Do you want the objects to be set active for everyone or only locally? Your use of "local" confuses me here.

[bleak magnet]

im trying to have everything local this is my manual cull. when a player leaves a room they load into another room. the teleport is them moving to next room while the objects active true and objects active false controls what that player loads into during the teleport

with the interact it would work fine but because i need it to be a walk in for what ever reason it wants to be global by default.

[bleak magnet]

i think i figured it out

i think this solves it

tbh the 1st branch on the tp might not be needed at all

[visual gale]

I already solved it and published thank you

[visual gale]

advanced udon graph user LOL

thas a lot of udon graph

[bleak magnet]

lol no i suck at udon and wish they didnt ditch 2.0

[visual gale]

ong same

2.0 was best

[bleak magnet]

too much extra steps less user friendly and easier to break

[visual gale]

udon does allow for some custom scripting tho something never possible before on vrchat worlds

which is nice

quality of worlds has increased with udon

[bleak magnet]

ya i just wish 2.0 had udon applied on top of it not seperated my world im converting slowly has like 16 rooms in it and the new object sync doesnt work with my animations

[visual gale]

i just wish they could have coexisted

guess not tho

[bleak magnet]

cyan made a trigger system but i decided to just do it the hard way

[visual gale]

UdonSharp is the new thing now

udon is going obsolete lol

[visual gale]

same

I had to relearn everything for my world

[bleak magnet]

think there keeping nodes

they should both work together

[visual gale]

no reason not to keep nodes

lol

[topaz jetty]

they will keep nodes, udonsharp is just a compiler made by someone, not the vrchat team

although they did hire the person that made it recently

[bleak magnet]

kinda wish udon had a pre made node system for multiple things like how they did player mods in the world asset that gives you your jump etc in udon

[visual gale]

yeah they hired them

idk im more comfortable with nodes lol

my friend says he only knows how to use udon# and not the graph LOLLLL

[topaz jetty]

same here lol

[visual gale]

the graph is too advanced for people??

lol

[topaz jetty]

wrote thousands of lines of u# code but never used graph

[bleak magnet]

nodes is easier on my eyes scripting is giving my html5 flash back in my game design classes lol..

[visual gale]

graph is easier imo

[bleak magnet]

graph seems easier but slower than scripting

[topaz jetty]

for small things it is yeah but if you wanna make something complex graph only slows things down and makes things more confusing

it's harder to keep order for very big scripts

[visual gale]

I only make hangout worlds

im not a game dev

so graph works fine for me

[topaz jetty]

yeah then graph is fine

though still prefer u# even for small things lol

[visual gale]

yeah even with avatar peds i use graph i can not use the U# shit idk how that works lol

[topaz jetty]

it's faster than dragging nodes

[visual gale]

code ew 😂

[bleak magnet]

i reccomand using the block nodes to keep things clean like how i did on my game set actives true and false collumes

[visual gale]

its code i have to learn and im not willing lol

[topaz jetty]

and in graph you don't have function arguments and function returns which makes everything aside from simple things like a million times more tedious to do

[bleak magnet]

my collumes will get pretty long im using a is trigger at spawn to reset the world to its defaults

[visual gale]

i mean thats not that hard

I also use legacylocomotion bc Nostalgic old locomotion Sdk2 style chad moment

[bleak magnet]

im keeping udon close to how my 2.0 logic was so if vrchat ever just poofs my unity will have easy to redo with any trigger system

[visual gale]

ye

[topaz jetty]

doubt vrchat would poof but other unity based social vr games live on lol

[bleak magnet]

for complicated games i would say scripting might be best if can use but i would still node

[topaz jetty]

if anything would succeed vrchat it'd probably run on a custom engine

[bleak magnet]

hope vrchat keeps lasting even tho i hate the udon and spending hours to figure out 1 thing that was fast in 2.0 wasnt fun but they did make something interesting just wish they stopped adding extra steps to ever update. dont fix it if it isnt broken

[topaz jetty]

just use cyantrigger if you don't like udon

I never used sdk2 but from what I've seen it looks a lot more annoying to use

but then again I've been programming for a few years so learning udon wasn't that hard for me

[bleak magnet]

i need to figure out how in udon you can make animation sync that the old object sync had. really need the old object sync bk xD

[topaz jetty]

yeah syncing is really annoying in udon

[bleak magnet]

the stuff the triggers did was fast but the over all syncs needed is still a pain even if i went with cyans

[topaz jetty]

https://docs.unity3d.com/ScriptReference/AnimationState-normalizedTime.html you could maybe sync a float variable in a continues sync and then make it set the normalized time on the clip, or if you want it to be less stutter you can make it check how big the difference is between the local animation's time and the master's animation's time and sync if it's above a certain threshold for less frequent stutters but larger individual stutters

[bleak magnet]

maybe but i have to see to kinda understand

spent all day figuring out my manual culling to be local

[topaz jetty]

haven't tried is yet but this should work if you use continues sync

[bleak magnet]

to replace object sync?

[topaz jetty]

no for the animation sync

for object sync just use the sdk3 object sync

[bleak magnet]

o ok so this is the part that 3.0 removed

[bleak magnet]

ya i use object sync on pick ups

just cant on my animations

ty

[sudden flume]

I cant find the scripts for these new contacts and receivers

[pallid roost]

That would be an #avatar-help question wouldn't it?

[sudden flume]

yeah I figured that out sry

lol

[zenith kiln]

why isnt my dynamic bones working at all for me on vrchat quest?

[topaz jetty]

The new physbones have to be added manually for quest avatars because the already uploaded quest avatars don't have dynamic bones on the quest versions, so they can't be converted to physbones either. It'll only work on newly uploaded avatars which right now (a few hours after launch) is pretty rare but you'll probably come across more soon

[neat jasper]

working on a game world with two rooms, a spectator area and a play area—i want players inside the spectator area to be able to hear everyone, but players inside the play area should only hear other players inside the play area.

is there known good practice for doing this so i don't have to go crazy in local testing? searching for anything involving "mute" makes the results a giant mess, LOL

[pallid roost]

That should be pretty simple. Are the rooms near eachother or far apart? If they are far apart you could just set the voice far value of everyone in the other game room to far for thenprople inside the spectator room

[pallid roost]

If it's nearby and you might need to turn down the people inside the spectator room for thrbpayers so they can't hear them

[neat jasper]

it’s around a 3-second walk, LMAO

are OnPlayerTriggerEnter / OnPlayerTriggerExit reliable for players besides your own?

[full jetty]

How do I set ownership of an object to a player?

[pallid roost]

It is in my experience so far. I have written a script that makes everyone inside a collider not be able to hear everyone outside and vice versa. And sync that for late joiners

[neat jasper]

nod

aaight, thank you for the information

if you've got that script uploaded anywhere, would be cool, but as long as trigger regions are reliable this doesn't seem too bad

[pallid roost]

I don't believe I do. It could definitely be written better too, I only needed it for one room but if you wanted multiple it would be better to move the playlist management to a separate behavior as I had it all in one script.

I can find it after work if you need but it wasn't too complicated to do.

[neat jasper]

i'd appreciate it if it's not too much trouble, just because testing networked stuff from a single PC is a huge drag—I only need a single zone as well

if nothing else, it'd be a nice reference to have for late-joiner stuff

[feral merlin]

Is it possible to have udon (or unity in general) read data from a spreadsheet?

[grand temple]

yes, you can reference .txt files as a TextAsset

dump your spreadsheet in there, use string operations to split and parse it

[pallid roost]

I always just use the launch multiple clients for that in the sdk menu. Gets the job done.
I'll put it on my GitHub after work tho.

[feral merlin]

I may need your help with this further in the future, is that okay? I'm making a VR Pokedex

[tribal widget]

My camera kinda died? How do I make it re-appear and show the lines of what it sees?

[indigo finch]

did you disable gizmos? (clicked this button)

[jaunty schooner]

I'm trying to make a video player emit light that casts shadows from dynamic objects. All the solutions out there which I've found so far for having a video player emit light can only handle baked shadows. I think a color changing shadow casting spotlight combined with a real time reflection probe would give me an effect which is good enough, but I need a way to sample the average color of the video that's playing. I'm guessing the fastest way to do that would be to sample the lowest level mipmap of the video player's rendertexture. Has anyone tried this? I'm pretty sure I've seen lighting effects in worlds which change color with the video that's playing, so I'm thinking someone has already made this work.

[pallid roost]

https://github.com/PiMaker/ltcgi
Ltcgi is probably what you've seen before

But that still only has static shadows

I'm pretty sure you can sample pixel colour from a render texture though and use that to set a spotlight colour

[pallid roost]

https://github.com/ModerateWinGuy/USharp-Scripts/blob/master/AudioOcclusionZone.cs

[neat jasper]

tysm! really appreciate it

[pallid roost]

No worries

[jaunty thistle]

Im pulling my hair out. When i teleport the room does not get enabled and i just fall. It was working a minute ago then i change something unrelated and it breaks?!? What is wrong

[bleak magnet]

if you change something and it breaks it might of broke the chain. from experience i found if in your var list in the inspector area has any empty areas ( self game object) that can break your set up. i dont know much about udon and i been using a differnt system to interact with the manual culling and tp

[jaunty thistle]

I thought so too so i went and disabled the one other script that messes with it and it remains broken. This has happened before but randomly started working again until now.

[bleak magnet]

if you didnt save after the break you can restart unity and reload it to fix usually sounds like something i had happen to me when i stuck the wrong nodes together and my ok green switch became a red ! even after completly redoing the nodes in script. or if you cant fix the script try a new 1 with the bare min to test making sure you complie it and have a green ok.

[jaunty thistle]

too late already saved over it unfortunately

[bleak magnet]

can try and save that script put to the side and make a new 1 to try again?

just make sure you compile and its green

[jaunty thistle]

the script wasn complicated so i already deleted its contents and started over

[bleak magnet]

o ok

[jaunty thistle]

yeah no other script is using anythin related and the gameobject doesnt get turned on

ok well i fixed it

i changed nothing just kept recompiling and testing

[bleak magnet]

ya udon does that. spent a whole day doing my tp on enter and manual culling. things kept breaking or reverting to global instead of local lol

[bleak magnet]

does the block do the nodes in order from top to bottom? i need to reorder my teleport so the next room loads b4 you get there or at same time to remove flickering of things being activated

well fixed my issue i removed the exit trigger for culling and only used enter trigger for both and have the tp and culling attached to a block. flickering is gone

is the get local really needed or could i just use direct with the branch switched to false? trying to simplify a little more since i have to repeat this for my other 16+ rooms and i don't think i can copy nodes over to new scripts lol. will be at least 30+ doors left to plug bk together from my 2.0

[elder peak]

why would you copy this over?
there is an idiom known in computer science (and many other aspects of life...) DRY: don't repeat yourself

it's a bit hard to follow your graph, as most is not shown
just note, you cannot teleport anyone but yourself

[bleak magnet]

its manual culling for local

everything after the block is either teleport or the 2 set game object actives

[elder peak]

that does not really explain why you need multiple graphs when you can just use the behaviour again

[robust venture]

why do i see other ppl fall avatars and hwo to turn it off

[turbid bear]

does anyone know how to have 2 different sounds play when interacted with?

[loud bridge]

Store them as separate references and just call Play() on one after the other.

[turbid bear]

ok how would i do that

[loud bridge]

https://docs.unity3d.com/ScriptReference/AudioSource.Play.html

[turbid bear]

sorry i dont use or know how to use c#

ive been using graph

[loud bridge]

Yeah, that function is available in Udon Graph. Udon just mirrors Unity's C# library.

(most of it, anyway)

[turbid bear]

ok

[loud bridge]

So, I heard a rumor that Avatar Pedestals can be used for persistent world data... does anyone know anything about this that can expand on the subject?

[cunning basin]

there's the avatar image reader project "Decodes UTF16 strings from image data stored in avatar pedestals. Allows you to update text inside a world without updating the entire world."

[loud bridge]

Bingo. That's probably what I heard about. I'll look into it.

[feral tartan]

I have a UdonSharpBehavior question:

How can I set from script 1
Namespace.Class.Void();
so it runs in script 2?
Both are UdonSharpBehavior c# script but on 2 different GameObjects.

Because

using namespace; //Namespace from script on different GameObject

public class blabla :UdonSharpBehavior
{
  public class MyClass
  {
      public static void Main()
      {
           var anInstanceofMyClass = new MyClass2();
          anInstanceofMyClass.TestCall();
      }
  }
}

is not working in Udon.

Or when I do:

using namespace; //Namespace from script on different GameObject

public class blabla :UdonSharpBehavior
{
  public class MyClass
  {
      public static void Main()
      {
          MyClass2.TestCall();
      }
  }
}

Then I get an CS0120 (An object reference is required for the nonstatic field, method, or property 'member') error.
Thank you in advanced.

[loud bridge]

(A) you really shouldn't be nesting classes in UdonSharp.
(B) You shouldn't be using statics either, generally
(C) You need to store a reference to the object on which you want to invoke the method as a class member. Then you can assign that reference in Unity's inspector window.

[elfin kestrel]

Trying to make a button that disables all world audio (audio caused by a toggle on/off button with the audio attached to it). All I want the button to do is turn off the audio, that's it. And then I can go back to pressing the audio toggle buttons and they continue to work. I tried one way but it caused the original button (the toggle audio) to not work at all,

The image shows the code being used to mute all audio. The intended effect being as if a player pressed the toggle button, but it happens to all toggle buttons at once. This current code as I said stops the original button from working however.

So literally just a stop button, that's what i'm tryna make, but it no work

[loud bridge]

Did you assign the audio source in question to the "newVariable" slot in the inspector?

[feral tartan]

Do you mean something like this?:

public class blabla :UdonSharpBehavior
{
  [SerializeField] private UdonBehaviour OtherGameObjectScript;
  public class MyClass
  {
      public static void Main()
      {
          OtherGameObjectScript.Invoke()
      }
  }
}```

[loud bridge]

That's better, but you still need to stop nesting classes. And there is no Main function in Unity. You probably want to use Start or Update (and not static).

[feral tartan]

Ok, I can see If I can make a work around without nesting. The Main was only for this example.

[elfin kestrel]

yep, it stops the audio as intended

then the original button stops working completely

[loud bridge]

What's the code for the original button?

[elfin kestrel]

had to rearrange to fit into a single pic

(no code changed)

[loud bridge]

Looks to me like you just may need to press it twice after using the mute button (because the mute button won't ever effect the "Toggle" boolean).
Also, you could refactor that toggle boolean completely out and just branch on the AudioSource's isPlaying property.

[elfin kestrel]

i'm going to try something drastic, i'll update you (i tried that way btw and still no)

[clear root]

How would I make a interact that would reset multiple moveable objects to original positions?

[spark walrus]

your interact would preferably send a custom event that is used on all object-scipts that you want to reset

[indigo finch]

Provided they all have an object sync component on them, you could create an object sync [ ], and cycle through it with a for loop, playing the node objectSync, respawn.
Here's a video on that: https://youtu.be/nSIFN9rRcQs

[clear root]

Ty, the video will really help

[indigo finch]

Do check the comments though, as I forgot to do something in this followup video

[clear root]

This will just respawn all objects with an object sync attached correct?

[loud bridge]

Not if you store them as a class member array and assign the ones you want in the object's inspector

[indigo finch]

This will create an array, which is essentially a list, to which you can fill in the slots in the inspector, of all the objects that you want it to respawn when you click the button. You will have to fill out the list in the inspector

[indigo finch]

Dude, he's a beginner... Simplify your language...

[indigo finch]

I would recommend watching the first video covering how to respawn 1 object, to get some context

[clear root]

Thanks 🙏🏼 and ok I’ll do that after work and yes beginner is a overstatement

[indigo finch]

We all start from somewhere. Feel free to ask around if you get stuck ^^

[clear root]

Got it to work thanks for the help

[indigo finch]

glad it helped ^^

[clear root]

very much so, so do your other videos

[clear root]

actual just one thing, when i interact with the button the first time, it resets everything, but if i move the obejcts again, it wont reset them a second time?

[magic drift]

Wrong chat but probably because of your Max download size in safety settings

[indigo finch]

huh.. that sounds like the script is crashing after it respawns the objects. Mind sharing a screenshot of your scene/ code (windows key + shift + s hotkey to screenshot only part of your screen)

[indigo finch]

and can I see the inspector?

[indigo finch]

Sorry, I meant that i wanted to see the whole udon behaviour in the inspector. Including this bit

[clear root]

it goes down more theres 92 in total

[indigo finch]

ah, there's the problem. you can't have any empty slots in the array. they were at the end, so the code crashed after it respawned everything above it. As unity is a bit of a pain for changing values causing it to reset values, I would (if your pc can handle it), change the array's size to 10092, and then delete the 100 from it

[clear root]

ah ok that makes sense, yeah pc definitley lagged when putting in 10092 but ive lost an array with a prefab i had before.... learned that the hard way

[indigo finch]

I could add some bit to the code to check if there is a value there, and therefore allowing for empty slots, but I kinda like having simpler code for tutorials

[clear root]

totally fair, it works now so thank you

[lament valve]

How do I reference the player's view camera?

[loud bridge]

You can use GetBonePosition/GetBoneRotation or GetTrackingData methods of the VRCPlayerApi instance:
https://docs.vrchat.com/docs/player-positions

I don't know if you can get a reference of the camera itself.

[lament valve]

Oh ok, thanks!

[thick mesa]

More or less an avatar question but um

Is it possible to add a custom script to an avatar?

I'd like a script that could change the value of the value inside the FX (Float Value) in increments when a Contact Receiver is set to true.

For example: The longer you press the nose, the farther the ears will slowly go down.

[indigo finch]

This is 100% an avatar question. Udon scripts can't be run on avatars, only worlds. That being said, there are a lot of hacks used with avatars, and with the new avatar dynamics, many more options are now available. I would ask in #avatar-help

[bold wren]

hi, i have a question, everytime i change my avatar in vr chat, my arms are down and i can't control it, is there a fix?

like i just cant control my avatar

[indigo finch]

this is a question for either #avatar-help, or #user-support-old

[bold wren]

ok ty

[brittle sphinx]

Hello there, im just new here. I just tried to build fresh and new UdonExampleScene, and those error appears. any ideas?
(also i want to know how to test in-editor, like player interactions)

[last geyser]

I got another question, I have two buttons that do the same action and are in sync with late joiners. But how do I get the other button to perform the same sequence by pressing button 1? and cause button 2 to also trigger? Reason for it cause When you press button 1 to open it and then press button 2. It will open too but 2nd time will close it. I want both button to be in sync with each other according to the interact.

[coarse parrot]

You need to have opening state in the door object. When a button is pressed, read state from the door it controls, then unary negate and set back to the door object.

[scarlet lake]

I cant test/build as this shows up -and im confused on why? the scene is downloaded is it as the scene needs to go onto evberything dropped into the world if you drop assessts/furnitre or?

[coarse parrot]

Look for previous errors too

[scarlet lake]

^^' I fixed it, i was trying to set up some pens and deleting that worked for some reason? might of eben a coding error releating to the pens

[tepid tiger]

Hi have a question if someone might know the issue. So I did buy vr today and was on PC before, and now I can’t use 90% of all my avatars and also can’t see others avatars, anyone know how to fix that?

[elder peak]

do you use a quest?

[crimson loom]

I have multiple toggle objects for udon graph, but how do I make it so activating one toggle will reset the others?

if that makes sense

because it's text and I don't want them to overlay on each other

[mental hamlet]

?

[outer rune]

More of a technical question than a true udon question, but should we expect any performance improvements with Udon considering the recent upgrades to the avatar SDK with this new unity compiler ? Currently udon can be hundreds of times slower than C# and figured there could potentially be more than meets the eye with this

[grand temple]

no, burst compiler is not being used in udon

[outer rune]

Sorry, let me ask this in a different way, are there plans of having the udon vm run through burst in the future ? I know udon code itself won't ever run through burst

[grand temple]

I'm not entirely familiar with burst, but it sounds like it's supposed to just work with the jobs system better. Udon is not multithreaded and even if it was, it would need massive changes to existing world scripts to take advantage of that

it seems like it would be quite the feat to get udon to interact with the jobs system though. I think there are better ways to get performance before introducing multithreading and jobs

[wooden wren]

Hi I don't know if we ask questions here or not but I'm looking for avatars with the dynamic bones trait since it just recently came out on Oculus I'm trying to find some people that know where good ones are for females

[solar crater]

Hey!
does Udon work with 2d arrays or jagged arrays?
ive seen that it doesnt work with 2d arrays but using a jagged array just results in this and im not sure why

[worldly tapir]

I'm using jagged arrays in my project and it works fine. normal 2D arrays are sadly not supported.
Check for IndexOutOfBounds errors, put some logs of your index and the length()s in your code.

[grand temple]

make sure that you initialize all layers of the jagged array

it's just putting an array inside an array, so if the children arrays are still empty then trying to access them will not work, same as any other array

[worldly tapir]

btw, did something weird change with canvases and buttons in the last six months?
My old canvases still work perfectly well, but if I make a new one and add buttons within a panel, they don't work.

Image: blue marked button works, red marked button doesn't work. They have the same setup, the canvas has the UdonUIShape on it.
the not-working ones don't even turn darker when clicked, so it's not a script error.

All of them work in unity play mode, but not when built, so it has to be something with the canvas I guess...?

[grand temple]

are you sure it's not being hidden behind that text?

[worldly tapir]

I don't think so, looks fine to me

the "i" is slightly obstructed but works perfectly well

[grand temple]

there's some other element there, is that the text that says minimum local buffer? Or the 40ms?

try going through the common problems here https://docs.vrchat.com/docs/vrc_uishape

[worldly tapir]

accidentally rotated the canvas in the last screenshot, text got hidden behind the mesh.
these things also seem fine, I'll read through the link you sent now ^^

[grand temple]

that doesn't look fine though, that looks like it's pretty clearly sitting directly on top of the buttons

[worldly tapir]

thick white outline is a panel that contains the 40ms and the buttons.

[grand temple]

hmmm ok

could be one of the other things in the link then

[worldly tapir]

things in the link are all things I already checked.
Might just have to make some mesh buttons instead, adds the benefit of showing the interaction text when pointed at

[grand temple]

could you show me the button's events?

[worldly tapir]

sure thing.
But again, not even getting the darker tone, so it's probably not reaching that part.

[grand temple]

ah, if it works in play mode but not vrc then it's usually something wrong with the vrc uishape

can I see the whole gameobject of the canvas, including the collider if it has one?

[grand temple]

the inspector?

[worldly tapir]

1 sec

oh god damn it.
apparently it was because it was parented to a gameobject and rotated 180°.
unparented it, now it works...

[ebon musk]

So I tried to convert a C# script to an udon script and it seems to have broken every script in my Project

[errant ivy]

Can you make an API get request in udon?

[ebon musk]

Does anyone know how one would go about making an engine sound that is variable to speed?

I am trying to convert the standard assets script but its much more complicated than expected

[indigo finch]

Converting scripts would be a hassle to walk someone through, but here is my two cents for this question. I did this for a hoverbike world I made (and later abandoned), and at first I used a bunch of animations, and put them all into a blend node in an animator. Then I could change the float parameter on the animator, via udon.
Later on though, I just went for a basic pitch change, and this was the code for that:

something I did notice however, is that it would stutter like crazy if I had a vrc audio Source on it, but it was fine with just the standard unity one. thinking back to it now, it may be because I did it on update, and not late update or something, but I'm sure someone else would know more

[last geyser]

I've come to a realization that the script I been working on for a week, Is overcomplicated but unable to create a simple Graph of a certain thing.

Udon Behavior 1 is suppose to spawn food onto the plate which looks like this

Udon Behavior 2 is suppose to be on the food that when you interact with the food, It becomes unparent which looks like this

and mouse interaction which causes the food to be eaten and disappear looks like this.

Problem is this whole thing isn't properly graphed properly, Which Behavior 1 is activated and works fine but Behavior 2 is obsolete because the first one is using the animation that causes it to constantly play and never change with the 2nd one being triggered as well the the 3rd. I am not exactly too sure how to even graph this whole thing properly. Despite the tips I been given, It hasn't been working too well.

[vapid niche]

Okay, so I’m trying to make a toggle in which I press a button, it sets an entire area inactive. (I have the transport script)

I have something sort of working, but its under the premonition that something is already inactive. I feel like this should just be an easy script to make but yet I can’t figure it out

[forest mist]

Hey, dumb question but how do you get Comments in Udon?

It's not showing up in search, and it's not under Special ->

Update: I am not a smart man

[lament valve]

How do you make something work globally in U#?

[arctic scarab]

how i make function synced for everyone

[arctic scarab]

hmm i see i have to sync entire class

[worldly tapir]

please specify what you mean with "something". Otherwise, the answer is just "synchronization"

[worldly tapir]

SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, "EventNameAsString") for U#
or a node also called SendCustomNetworkEvent in the node graph

[topaz jetty]

note that this does not execute it afterwards for late joiners, so if you're changing the state of something, like opening/closing a door, used synced variables instead

[agile harbor]

Does anyone know how to get the pens to work when editing in android? I got them to finally load into my quest world but nothing happens when you try to draw with them, the tail length is .5 also

[arctic scarab]

can you tell bit more

[worldly tapir]

Are you using nodes or U#?

[arctic scarab]

u#

and since i dont know csharp at all

main difficulty is that function has rng in it so i cant put it whole into sync as everyone will have different results

    public override void Interact() {
        GameObject test = GameObject.Find("Deck1");
        if(test.transform.childCount != 0f){
        Transform selection = test.transform.GetChild(Random.Range(0, test.transform.childCount));
        selection.parent = GameObject.Find("Deck1 active").transform;
        selection.gameObject.SetActive(true);
        selection.position = new Vector3(6, 1, -1);
        }
    }```

[worldly tapir]

Alright.
If you want a function to be executed by everyone that's currently in the world, use the line I posted earlier.
Keep in mind that this is fire-and-forget. doing e.g.
SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, "CloseEntranceDoor")
will, provided you have a function called "CloseEntranceDoor()", fire that function for everyone. Players that join after this line has been executed will not receive this call.

If you want something to be synchronised for everyone, even when they join late, you use synced variables.
Put a "[UdonSynced]" above a variable to sync it. Since SemdCustomNetworkEvent does not directly allow you to transfer variables, you can use this in your case too.

Now, there's two methods of synchronisation, only one can be selected per behaviour:
continuous and manual.
synced variables in a continuously synced script will always stay synchronised on all clients, while manual synced script sync all variables only when you call "RequestSerialization".

[arctic scarab]

i would use synced variables but these seem to have much more work with them

[worldly tapir]

They do make things a little more complicated. Keep in mind that you can always use both (any)synced variables and SendCustomNetworkEvent together., this can sometimes make things simpler.

[arctic scarab]

as soon i paste in udonsynced im having lots of errors

[worldly tapir]

a bit difficult in your case since transform can't be synced yet. I gotta test something really quick, back in 5 minutes or something

[arctic scarab]

i mean if i only can sync values like ints and bools then i would need another function that assigns them to correct places

[brave granite]

ok so i want to make a basic udon ai. just an avatar that look at the player for now but not sure what to program or where to start with this anyone have any advice. i can already do basic codeing in udon so no basic tuttorials plz

[brave granite]

guess what i would like to know is how to get a players viewball location?

[worldly tapir]

I don't know exactly what your goal is with these functions but one way to do this would be to put a UdonBehaviour onto your child objects that contains a synced bool (manual if you don't need to keep changes for new joiners, continuous if you do).
Then, on OnDeserialization, use the bool to see whether the child should be to its new parent and do all the other operations there if the bool doesn't match its status.

[arctic scarab]

theres like 100 child objects

so id rather keep all script in spawner script

[worldly tapir]

I don't know about the camera, but you can get a players head transform using
Transform _playerHeadTransform = Networking.LocalPlayer.GetBoneTransform(HumanBodyBones.Head);.
or just its position using
Vector3 _playerHeadPosition = Networking.LocalPlayer.GetBonePosition(HumanBodyBones.Head);

[arctic scarab]

can i just make one more script that will auto sync whenever player joins or value changes

[brave granite]

thats a start for sure thanks.

[worldly tapir]

...apparently you can replace the Networking.LocalPlayer. and just use VRCPlayerAPI. instead

[arctic scarab]

cant i make synced variable have sync like object sync component?

[worldly tapir]

you can definitely do that. Do not be afraid to have a small script on 100 objects though, especially if it's just used as a container for manual syncing.
Keep in mind that, if you have one script dedicated to syncing, it will sync all variables of all child objects you want to keep track of, you can't sync a single one.
Using a script to keep track of syncs while the syncs themselves happen in these container scripts on the individual object keeps network traffic low.

[worldly tapir]

I don't know what you mean by this, sorry ^^

[arctic scarab]

like vrchat automatically manages grabbables

and dont have to do anything more with them as they are always synced properly

hoever when i want to change position or toggle objects then all changes are just for one player

i would like each position or state change be shared across clients

[worldly tapir]

that's basically any UdonSynced variable in a continuously synced script

[arctic scarab]

but problem is i probably have to all time run loop that syncs it

and index everything

[worldly tapir]

that's why I'd just put the sync script on the individual objects and see how well that works. Saves a lot of hassle

if you join, send an event to the world owner/master that tells all objects with the script to RequestSerialization

[spark walrus]

can you get a list of the child_objects from the script of the parent? How can i send a custom event to the child?

[brave granite]

@spark walrus well you can send a custom networking event and then recieve that event on the child object.

[brave granite]

@spark walrus you can also use an animators perameters as well.

[scarlet lake]

How do make things with udon?

[compact stirrup]

Did the avatar dynamics update do something to framerate-based calculations? like are update and fixed update no longer framerate dependent or something?

pinned message #udon-general message

[brittle sphinx]

Hi there, I'm currently using UdonSharp, and I just tried to test TriggerCollision

 private void OnTriggerEnter(Collider other) {
        if(other.TryGetComponent<OdenBehavior>(out OdenBehavior oden)) {
            oden.SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, "Fry");
        } 
    }

and Error appears like this

Assets\Scripts\UdonBehaviors\OdenSoupBehavior.cs(15,51): System.NotSupportedException: UdonSharp does not currently support node type DeclarationExpression

any ideas?

[grand temple]

use GetComponent instead of TryGetComponent

then if you need to check for success, you use utilities.isvalid

[brittle sphinx]

it works PERFECTLY!! thank you sooo much

[grand temple]

I would also recommend doing utilities.isvalid on the original collider other just in case. There are some cases where it is possible to receive ontriggerenter from a protected object like vrchat's UI or player colliders

[brittle sphinx]

Wait... what? then I should use Utilities.isVaild(<somthing Collider>) for just in case...

another short question, how can I detect runtime exception during test?

[grand temple]

you can watch your log for exceptions

which you can access ingame with rshift + tilde + 3

or you can set up the udonsharp log watcher in edit > project settings > udonsharp. This tool will watch your logs for errors and create the error in the unity editor, and clicking on the error will bring you to the exact line of code in C# where it happened

[brittle sphinx]

what a great advices!! T_T that solves all for now!

Thank you sooo much!

VRChat Udon is a programming language built by the VRChat Development Team for use in VRChat worlds! It enables complex behaviors and logic in VRChat worlds. Read more about Udon in our documentation: https://docs.vrchat.com/docs/what-is-udon

[arctic scarab]

can i get object origin position

[tribal meadow]

is it possible that an udon behaviour script could overide your proximity settings in the pickup script? It doesn't seem to matter what I set the pickup proximity to, it does not change (you are able to grab the object from too far away) looking for possible causes. Object is in the root of the hierarchy. Collider is the same size as the object. Also does the order the scripts go within the inspector matter?

[indigo finch]

are you testing this on desktop or vr? I believe it only effects vr

[tribal meadow]

VR

Basically you can see here how far away the object is interacting with the player, even though it's set to almost nothing. Is the proximity setting only for non pickup-able objects? and if so, how would I adjust the proximity for grabbable objects? This is being used on a lighting control system so there are many of these objects, so when the proximity is this high, you often end up getting the wrong object, or it interferes with other non grabbable objects.

[indigo finch]

what if you actually set it to nothing. can you pick it up?

[tribal meadow]

yes

makes no difference

It looks like the proximity for movable objects is preset. The proximity setting only effects static objects like a button or toggle. This also seems to be the case for canvas UI objects, the proximity setting has no effect on that either. I put in a feature request for pickup object proximity (unless anyone else has some ideas) I see others are asking for this for the canvas UI as well.

[ebon musk]

How would one go about disabling player collisions when in a seat?

[indigo finch]

Set their layer to walkthrough using a gameObject.set layer node, with the event onStationEntered. Either that, or use collider.set enabled node

[zealous vector]

is the phizbones in unity already or is it a file I need to find and download

[clever flare]

#avatar-dynamics

[vapid niche]

alright, I have my world and I have areas load and deload on teleport, mainly for optimization. However, I need to add a script that like, sets the main area active on respawn, as I have several people who do this to get to the spawn point to see their friends quickly. Is this even possible?

[indigo finch]

Depends on how your choosing what parts to load and deload in. Usually I would have it setup with an int that says what part to have loaded in, and then just change that int when I enter a different area.
Then all I would have to do is have a event OnPlayerRespawn node, and get it to set the int to the starting zone (usually 0 for me)

[vapid niche]

I managed to make a work around.
I have a platform under the respawn point that you fall on. From there I have two buttons that need to be clicked that gives the reverse. You have to respawn twice, but it works for now.

[ebon musk]

I can't seem to find a node that allows me to connect playerApi output from OnStationEntered to the gameobject. set layer or to the get collider node to use collider.set enabled

[indigo finch]

the playerApi is saying what player entered the station. it doesn't contain any information about the object you want to change the layer of.
From the playerapi, put that into a playerapi. is local node. that will give us a bool to say whether or not it was us, the local player, that entered the station. Then put that into a branch node with the arrow from our onStationEntered plug into it's arrow slot. Now we only want to toggle our object if we were the one to enter the station, so coming out from the true arrow, we want to plug that into a gameobject, set layer node.

this node requires both a object to change it's layer (the instance slot), as well as the layer we want to change it to (walkthrough layer = 17). Go up to your variables tab, hit the little plus button, and create a gameobject variable. Give it a name, and hit the little dropdown and make it public. Then plug it into the instance slot.

When using the code, you will need to plug the target gameobject into this slot, in the inspector.

[ebon musk]

Oh wait! I had wanted to set it so it disabled player collisions so it would still interact with other players. It now occurs to me that the state of the colliders is local so any change made would be local to the player in the seat, so changing the layer would not impact other Udon code and collisions running on other players, correct?

[indigo finch]

yup, it's local

[ebon musk]

Now to find a layer that doesn't collide with player or walkthrough lol

Or would it be playerlocal?

[magic drift]

How would I make an area that sends an event or trigger if an object is placed on it? (or a certain amount of specific objects)
preferably using Cyantrigger

[indigo finch]

Help someone make one a while ago, that was if enough mugs where placed on a table, the table would break. This was the script that went on the object being placed on the table:

[indigo finch]

and then this was placed on the table itself

[worldly tapir]

@red gazelle thank you for the nice words!

To answer your question, yes, as you probably noticed it recognizes note-on events at note-off when velocity is zero. This is common practice for modern midi devices, it's just that a lot of people don't read the midi spec when making maps, since note-on and off seem so intuitive :D

For the networking, I'll have to answer that laer because my break is over rn, sorry :P

[grim bluff]

Hey guys!
I'm in a bit of a pickle.
I have base64 strings of images in a json file that I want to load in vrc.
Is there any way I can convert these strings to images/textures?
I have tried creating a new Texture but Udon doesn't support the constructor of this.
If you have any idea's, thank you in advance!

Oh good grief it’s an hour 😂

Oh well

hi there, so uhm, udon just screwed up my complete project, and now i cannot even use it in a new project anymore, cuz im already getting 36 errors, is anyone mabey able to help me?

what is the latest udon version rn?

[pure scarab]

UdonSharp_V0.20.3

[dapper lion]

what is sdk version?

and also show errors plz

[arctic scarab]

why vector3 position is double and not float

i cant change to position with dots

[river musk]

Is there a way to make a point system using buttons to add certain points on a scoreboard of text?

[river musk]

I want it to add a number to text with one button, but if a second button is pressed a different amount from the first button is added ontop like a counter. Ive tried using ints but it just replaces the existing number instead of adding with the amount there.

[wind atlas]

You'd usually have something like a "counter" int which you display on the UI. Let's say a button press is a + 1. That means you increase "counter" by one and then update the UI with the new value.

Not sure if that's what you meant though.

You could try posting what you tried.

[river musk]

This is what I had so far

[wind atlas]

Are you trying to use a for loop to increase the number? Try creating a variable and display that as I suggested before.

[river musk]

All I want is that when this custom event happens, I want it to add numbers from the addition Int to the text and if there is already a number on the text to add ontop not replace it

[river musk]

There is no counter Int

[dawn forge]

Is there a way force a user into a defined avatar or scale to specific dimensions for the duration of the map visit or in order to participate?

[wind atlas]

You have to create that int yourself in the variable creating window.

You use that to store your counter, then add to it, and then to display it as text.

[wind atlas]

I don't think you can force them for the whole duration, but I'm pretty sure you can force them into avatars, there is a method for that.

[river musk]

How do I connect the variable to the addition int?

[wind atlas]

When you drag in a variable, it shows you that you can get or set it (and their hotkeys). Use get to drag it into the addition node, then drag the output of that into the set node.

[river musk]

Like this?

[dawn forge]

Know the function by chance? I am just needing to enforce consistent dimensions for fairness and to expose hitboxes as needed for workable combat mechanics.

[jaunty fiber]

I have a feeling I already know the answer to this, but
I have an idea for a game and would like to automatically post and store user scores via a webserver.

I know that using the video player I can do GET requests, but is there anyway to parse responses coming in from that?
Also, are you able to change the header and body of that request?

[wind atlas]

No, you are using using the wrong get. Notice how it says Int32[], you need the one without the brackets. Just drag counter in and it shows you the hotkeys for it.

Also, you don't really need the for loop, I'm really confused why you are using it.

It looks like you are missing some coding basics, so I might make a graph myself in a bit when I have time.

[wind atlas]

It's the VRC_AvatarPedestal, which has SetAvatarUse. Not sure if it's the right one since I never used it, but that's the only one I found so far.

[river musk]

Im having trouble finding it, Do you mean get value? There is no other get node besides the one you said is wrong

[wind atlas]

Drag and drop the variable, it shows you the hotkeys

[wind atlas]

Something like this:

CTRL is for making a set node

[river musk]

So the Set Counter is what I need?

I just tested this and it works by itself but with all my shit i did I need to fix it

[pure scarab]

i have soo much errors with udonsharp, is there anyone able to help me for a sec? i already recreated my world 3 times.

[pallid roost]

Do you have the errors in the fresh world?

Right after importing the vrc world sdk and udon#?

[pure scarab]

i do yeah, right after importing both of them.

i just got it working, but the errors are still there, and when i click play, it even gives me more errors.

[pallid roost]

What are your steps for importing things? You must have a wrong version of something or doing it in the wrong order

What versions of you have of:
Vrchat word sdk
Udon#
Unity

[pure scarab]

all of them the newest ones, i just downloaded everything fresh

and unity is 2019.4.31f1

[pallid roost]

What are the errors your getting?

Screenshot your console scrolled up to the top

[torn pendant]

is there any prefab that let you add picture as a slide?

like a powerpoint presentation

[near quiver]

Hi, random question, can anyone tell me how to go about restricting arm and such movement in vrc world stations? The custom animation I have always plays for a second before giving tracking back. I haven't been able to find information on how, so I'm asking around.

[magic drift]

If I wanted to make the players speed
4.317 m/s walking, 5.612 meters/second running, and jump 1 1⁄4 m, what would I need the values to be in VRCWorldSettings?

[indigo finch]

dunno, but set the walk speed to 1, measure how far you walk in 1 seconds (or 1 minute and divide by 60), and set that as the value

[torn pendant]

Hi!

so in Udon script graph does anybody know. for every object interaction the animator integer increases by 1?

[pallid roost]

TimesInteracted = TimesInteracted+1
Just do that on the interaction event

And then the logic to to pass the int to the animator

[pallid roost]

You need an interfer variable, and each time the interact event happens add one to it's value

And then provide that int to the value field on the setInterger

[pale sentinel]

Is there a way to play youtube playlists with udon media players?

[pallid roost]

No you have to play them with each individual youtube url

[solar crater]

Hey!
im trying to attach a script to a button's onclick event but im having issues with it.
What is the best way to accomplish this goal?
I have tried RunProgram but that doesnt seem to work.

[loud bridge]

Add a custom event to the script and then do this:

[arctic scarab]

how i make toggle for on/off certain object

[solar crater]

ill try this but ive had some issues subscribing the required function to the event and i thought it was just another udon limitation

but ill look into it

[solar crater]

It seems udon/udonsharp dont support delegates nor UnityEvents. how else could i add a custom event to my scripts?

[river musk]

Ok so this works on a singular button for points on a scoreboard, but when i hit another button to add more points it erases the original points and replaces with the new amount of points. So instead of having 37 points before the second button, after the second button is pressed it says 17 instead of 54.

[proud skiff]

Hey, i downloaded the VRC Billiard from Github, and when i put it in the scene, i get 138 script compile errors, has anyone else had this problem?

[river musk]

you need UdonSharp to load it

if you already have the sdk in

[pallid roost]

Make sure you follow the install instructions on the GitHub and get all the required stuff installed first

[proud skiff]

ohhhh okayy

i dont read

I just download it expecting to know what to do with it, like everything else thats successful in my life, lol

[loud bridge]

I don't think you can, directly. In theory, you could store an array of UdonBehaviour references and an array of strings of Custom Event names, then loop through and call custom event on each one. But for non-Udon applications, or to call U# functions with parameters, you'd need to hard-code it afaik.

[spiral spruce]

is there a way that i can make people not able to respawn

[pallid roost]

Not really no.

You could move the position of the respawn point to the users location so that when they do respawn they don't get anywhere tho?

But they're always gonna be able to click the respawn button

[spiral spruce]

How do ya do this

[pallid roost]

I've not tried it to be sure, but You could probably just move the vrc world object to the local player in an update event

Or just have a recursive event that does it every few seconds

[spiral spruce]

Would ya know how to set this up or where I can find info on this

[pallid roost]

I would but I'm on my phone so I honesty don't want to type out a full explanation. 🤣 It would be a pretty simple script.

1. Move object to the players position
2. Have the event call itself again with the custom event delayed by seconds event

[faint delta]

Hopefully a quick question. Is the Udon Start Event run on all clients by default upon entering the world? Or do you need to pull each one from a VRCPlayerAPI array using a For loop?

[pallid roost]

Yes, when an object is initialized it runs. For every client

[loud bridge]

• if its GameObject is active. If not, then it'll run on the first active frame

[pallid roost]

True true. Gotta keep an eye on that for some things.

[faint delta]

TY both

[rough mesa]

can anyone please tell me how to easily create a toggle button in my world that will change the skybox (rotate 3 even?) do i need to use udon to do this or a c# script?

[faint delta]

This may be more of a general VRchat question, but it also relates to Udon. Can a pickup that is held by a player still collide with a trigger in the world while being held, and generate an OnTriggerEnter event? (EDIT: It can, just answered my own question. I had something misconfigured).

[pallid roost]

You can do it in udon or udon sharp.

[rough mesa]

can you point me in the direction of a way to learn how to do this?

[pallid roost]

https://youtu.be/yC9h-51jvBg
Google does wonders 😝

[scarlet lake]

How would I go about making a shield that starts off small then grows into a larger one when you toggle it

I'd also like it to shrink when you toggle it again

Ideally it's something you would run around with in its small form then trigger it to grow into a large one

[pallid roost]

You could just make an animation for that that either scales it bigger / smaller, or have a blendshape to change the size / shape and make the animation blend between the two.

[true ore]

hey does anyone know why turning the fog on in cyantriggers doesn't work? i can turn on and off the gravity and most other things, but SetFog only works in CyanEmu, not once in vr, not even in a very basic scene. hopefully it's just something extra i have to do with my trigger i haven't thought of yet, and not something deeper that the sdk is preventing.

[true ore]

hmm, in a simple test it looks like if i start with fog on, and have it turned off once we enter the world, then i can turn it back on. i knew some udon stuff had to be on at runtime but didn't realize this was one of them.

[mental hamlet]

My animation is needing to send a custom event.
I have my custom event specified in animations but my Udon behaviour doesn't appear to be receiving the event.

This explains everything

[elder peak]

do you use SendCustomEvent? you cannot call the methods directly

it does not matter whether the udon behaviour is enabled, so that's not the issue here

[mental hamlet]

Yeah, I have start up firing the event.
Then each of my animations sends the event again that this behaviour catches now.
Seems to work now that I have the script I was using enabled

[elder peak]

what does the animation event look like?

[mental hamlet]

And also my amazing udon graph wow

[opal dew]

Augh, UdonSharp support for Interfaces when. grumble-grumble

[scarlet lake]

alright thank you

[river musk]

Does anyone know how to sync a single counter to multiple buttons?

[coral latch]

hello guys

I seem to be getting

200+ errors upon

literally having udon in the unity project

does anybody know why that could be the case

I seem to have the latest files so

can't see why such thing would occur

[vast sparrow]

some other assets might be calling for udon sharp not the regular udon check if thats the case

[coral latch]

I also have UdonSharp master

[river musk]

I wouldnt use master, I think all of that is uncompiled

Use the latest release

[coral latch]

I was just looking for a way to add a button to execute a sound that's all

could there be any recommendations towards this type of thing

[river musk]

You can use udon by itself for that

[coral latch]

oh I see

in that cause I could simply remove udon master

[river musk]

basically

[coral latch]

oh that fixed it

lmao

thank you

I have another question if you don't mind

when I play a sound, is there a way to let others also hear that sound

[river musk]

Use SendCustomNetworkEvent

[coral latch]

got it, thanks !

[vestal mica]

Hey i try to make a world camera. What material should i use for the render texture? Right now it dont look hq

[prisma bramble]

how do I make an object move towards the player with udon graph

[indigo finch]

I like to use unlit/texture, as monitors and tvs irl, absorb a who lot of ambient light

[vestal mica]

i have unlit :/

doesnt look sharp

[high mural]

probably need to increase the resolution of the texture

[vestal mica]

@high mural i did that also :/. could it be because i use stage lightning?

i have those strange artifacts

second is without world cam

[high mural]

yeah a camera render texture is never going to have the same fidelity as your actual view. could be something with shaders,, not sure. but that's probably about as good as you're going to get it to look, imo

[vestal mica]

I just saw the camera in ddvr club. there it looks waaay better

[high mural]

my guess would be something to do with shaders then, but idk for sure

[vestal mica]

hmmm i think that too.. but idk

but thanks for taking time to help me 🙂

[vestal mica]

how can i turn up my voice? i cant hear the others and they cant hear me well in my world

[loud bridge]

Looks like one is anti-aliased and the other is not. Pretty sure in this version of Unity, that's performed as a postprocess effect.

Not sure what you'd need to do to get it to work with the RT camera though.

[vestal mica]

Hmmm okey

[loud bridge]

You might try importing the PostProcess package from the Unity Package manager standard assets and apply a postprocess volume with an anti-alias effect.

[past lance]

Hey there, so I just created a FNaF style door toggle and uploaded it to vrchat, however, there seems to be an issue that when I toggle it closed, it doesn't show that for other players meaning they can just walk straight through it as they see it open. I'm assuming it's something I forgot to tick on a box somewhere but if anyone knows how to help, it would be much obliged

[pallid roost]

It's not as simple as a box. You need to atnc the door state to other users

[pallid roost]

There are plenty of good videos on YouTube explaining exactly how to do that

[past lance]

Ah thank u!

[worldly quartz]

hi! i put too many things on my unity scene and i think something is lagging out the loading is there a way to pause udon so i can laod only the geometry?

[past lance]

Hello there! So about the syncing toggle, could someone explain how to do it to an animation? I tried looking up a video on how to do so but I only get syncing object toggles and not animations. Any help would mean so much to me!

[tepid spade]

Hey my friend has a question and I am also having a question about what my friend's friend is experiencing but he's wanting to know what it means and I don't think he knows if it's a problem or not but I'll get to the point what does unverified player mean?

[pallid roost]

You need to pass that synced variable into the animator for the door

Instead of toggling the door shown / hidden

[indigo finch]

This should hopefully help:
https://youtu.be/hCK3oAH7WJg

[cosmic pike]

is there a way that I can set ramp steepness for players to still be able to climb? What's the angle across which collisions are interpreted as hitting a wall vs. hitting a ramp?

[feral merlin]

Would anyone be able to help me write a U# script to cycle through game objects using two UI buttons?

I have an idea of how the logic could work but no experience in coding

My idea is that it's controlled by an integer. Said integer increases by one with the press of a button, or decreases by one with the press of another button. Depending on the current integer value, a specific game object is displayed. I am willing to pay somebody to write this kind of script out.

[indigo finch]

Does it have to be udon#? You can have both udon# and udon graph codes running in the same scene, as they both get translated into udon assembler when uploaded to vrchat.

If udon graph is okay, there is actually an example script that sounds like it does everything you want. It does also have a ui text object on it, that displays the name of the gameobject that is being shown, but if you delete everything i've shown in red, it will get rid of that feature.

[feral merlin]

I'm not entirely sure how to set that up but I'll give it a go

Thank you

Doesn't seem to work but I probably did it wrong

[indigo finch]

I don't believe you can change the angle to which players can climb. I think it might even be 89 degrees. Here's a simple model for you do test with

[indigo finch]

How exactly does it not work? might be something simple

[feral merlin]

I click my UI button and nothing happens

[indigo finch]

mind showing the modified graph?

[feral merlin]

I didn't change anything aside from removing the one variable you said to delete

[indigo finch]

and that would be it...

you also need to delete the group i circled

[feral merlin]

Ahh I see

[indigo finch]

also it's just the nodes, not the lines going though it

[feral merlin]

Still seemingly nothing happening

[indigo finch]

graph pics please

[indigo finch]

btw, if you don't already know, windows key + shift + s allows you to screenshot only part of screen

[feral merlin]

That's what I'm using lol

[indigo finch]

^^

[feral merlin]

I still have friends that pin snipping tool to their taskbar and I just ask why every time

I feel like the program does most likely work though

[indigo finch]

yea, it do be like that...

mind hitting compile and reload button on the top right of the udongraph window? you block node is a little messed up

[feral merlin]

I just set up the button wrong I'm assuming

This is my first time working with UI canvases

[feral merlin]

I compiled, what do you mean by block node?

[indigo finch]

you've got a missing arrow in you block node. a reload/ recompile should be all it needs

[feral merlin]

Oh I see

There actually appears to be two arrows that aren't connected

One just disappeared when I dragged out and let go

Looks like this now

[indigo finch]

the bottom one doesn't matter. its having a gap that's the problem

[feral merlin]

Gotcha

[indigo finch]

yup, that's how it should be

[feral merlin]

Should I run a test now?

[indigo finch]

yup

your inspectors look right

[feral merlin]

Still not functioning properly...

The buttons are definitely registering inputs as the color change occurs when clicked

[indigo finch]

so, this code works by having the only the starting object active on launch. Then whenever it's clicked, it disables the old object, and enables the new one.

that being said, are you just after changing the colour of an object?

[feral merlin]

Yep, that's how my scene is set up

[feral merlin]

No

I'm making a VR Pokedex and cycling through various Pokemon using navigation buttons

The buttons have color changing set up in their components by default

[indigo finch]

hmm...

[indigo finch]

Okay, so I've just set it up on my end, and I didn't run into any issues. Just to be sure, here's the modified code that I used:

[feral merlin]

Alright, thank you so much

[indigo finch]

np ^^

[pallid roost]

Anyone had their project not generate a visual studio solution for some reason? normally i just open that to edit all my udon# but it isnt generating for some reason

[wind atlas]

Hmm, I always generate them manually anyway.
I know there is this: https://docs.unity3d.com/Manual/VisualStudioprojectgenerationWindows.html
But I've never done that before, maybe that's what you are looking for.

[loud bridge]

Typically, in Unity, it only does so once there are C# scripts. Create a script and double-click it in the Project window and it should generate everything on demand then.

[vestal mica]

thanks you

[loud bridge]

Anyone seen this before? Not really sure where to start with it because there's no context provided at all...

[modern wagon]

all my video players keep breaking and this is a constant error for them, plez help

[unborn hornet]

Are you trying to use the unity Play mode?

[ebon musk]

Is it possible to prevent other players from picking up a pickup once its been picked up?

[indigo finch]

this perhaps?

[brave granite]

alright so can someone help me figure out how to get a particle collision from a player so i can code with it? i know there is the event on player particle collision but i cant seem to do anything with that on its own even if the particle is sending collision messages

more specificly i can get a particle if its from the same game object but i want to get a particle emitted by a players avatar

or send information to the player itself to teleport it

[pallid roost]

What are you doing that specifically requires particles? As opposed to just normal object collision detection. Just curious what your trying to do.

[brave granite]

i am making a game where i need the player particles form an avatar to do damage to an object

i know i can make an object that does this like a gun or something but i want to use the avatars similar to the doom map for pc

[ebon musk]

Sorry left out the part where I mean after said person lets go. Like basically only that person can pick the item up after that point until they disconnect. I've changed methods now tho

[indigo finch]

Here's a script for a button to do this with udon graph: https://youtu.be/szetLivbmdc
It will work fine with your player, as it calls the video player component directly, and shouldn't interact with the udon# coding at all. You can also have both udon graph and udon# codes in your scene at the same time, as they both translate to udon assembler anyways

no worries. It's a little confusing, but the only thing that makes it an udon# video player, is all the inputs and ui for the video player, not the video player itself ^^

[orchid stag]

Hi!

Apparently I'm too stupid to set player tags. I've tried to do these things:

public Text tx
string t, tv = "hi";

public override void OnPlayerJoined(VRCPlayerApi player){
//player.SetPlayerTag(tv);
//player.SetPlayerTag(t, tv);
//player.SetPlayerTag("hello");

     //tx.text = player.GetPlayerTag(t);

}

But I can't seem to get it to work. What I want, is to assign every player with some tag, and when they enter a teleport trigger, they will be teleported according to what tag they have.

If someone can help me to get to the point, where I can get the player's tag in the Text output field, I'd be grateful 😅

[mighty fjord]

Wait, people actually use player tags?

[orchid stag]

I just found out about that apparent use today, so I have no idea what ppl normally do 😂

[fiery yoke]

Player Tags are actually pretty nice, but they are a bit of a black box and nobody knows if they really are supported or not lol

They are not really mentioned often...

[orchid stag]

Well accoding to this, which was updated 6 months ago, it should work, except
GetPlayersWithTag() 🤔

[spare beacon]

can someone explain what "Auto Fix" button in this case exactly do?

[mighty fjord]

Wasn't there an issue which could clear the all of the tags of a user when trying to remove a specific one or something?

[fiery yoke]

It should check the "automatic resync" box on the video player component. Should.
Not sure if there is a reason to keep it unchecked.

[spare beacon]

but there's no "Automatic resync" checkbox or i'm blind

[orchid stag]

not sure why you don't have it, I can see, that if I use the component, I have that tick

[fiery yoke]

It was added in some SDK version. Maybe something went wrong while you updated or something like that? Not really sure either

[spare beacon]

i'm using the latest SDK3 version on clean unity project

[spare beacon]

weird

[bleak magnet]

does udon allow unity buttons for resetting objects to a set location still?

i made this for 2.0 that allows you to move a light back to a given location

[orchid stag]

You need to use the Udon Interact(), and override that

Something like:

public override void Interact() {
SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, "MyFunction");
}

public void MyFunction(){}

[vocal sigil]

What does udon stand for

[hidden marten]

VRChat Udon is a programming language built by the VRChat Development Team for use in VRChat worlds! It enables complex behaviors and logic in VRChat worlds. Read more about Udon in our documentation: https://docs.vrchat.com/docs/what-is-udon

[worldly tapir]

Unity Doesn't Offer Nanites :(

[bleak magnet]

ty i got it to work in cyan triggers since the buttons just dont work like b4

[strange shale]

heya
question for anyone who might know
is it possible to make a 2D array of game objects in the udon graph?
was looking for anything that may work like that... even the option of a sort of array within array system but i cannot seem to find a function that would let me do that

basically was trying to set up a grid system for a game and a 2D array would be much preferred to alternative methods >_>

[worldly tapir]

2D arrays are not supported, but jagged arrays are.
Which are basically more loose, but less optimized 2D arrays.

instead of
int[,] myArray
you do
int[][] myArray.
here, every entry of the "top layer" array holds an array of unfixed size, meaning that entry 0 can carry an array of size 6, while entry 1 carries an array of size 2 or whatever you need.

[strange shale]

yeah that was basically one of the options i was looking for :3
while its good to know that it IS supported im still not certain where to find a node for a any[][] in the Udon graph
the available options seem to only contain single [] options
you wouldn't happen to know what i might need to search for to find a GameObject[][]?
if not i will just keep looking :3

[worldly tapir]

Oh I might have to disappoint you, My brain was still in Udon Sharp mode.
I don't think there's any 2D arrays in regular udon yet.

but you can always use a 1d array as a 2d array.

[strange shale]

no worries :3

a fine fella in another server suggested using an object[] to store GameObject[]s

in hindsight its kind of obvious i just kind of forgot that you could put anything in an Object field

thanks for the help anyway! :3

[worldly tapir]

That definitely looks like an easy solution! Otherwise, for fancy maths coding magic, you can map the grid onto a single dimension:
e.g. if you want a 8x8 grid, make an array of length 64 (so 8 times 8).
Let's say you have a Width(sizeX)5 and a Depth(sizeY)4:
Make an array of length 20 (aka 4*5 or sizeX*sizeY)
To access the fake 2d array's index (indexX=3, indexY=2), simply go to the "real" array's index of
indexX * sizeY + indexY

[strange shale]

funny enough you are kind of describing what i had though up as a sort of workaround solution x3
would be what i had gone with if i had not found a better solution

think the jagged array option will be easier on my brain to work with

especially given that i am self taught and there are precious few guides for this stuff

I'm having a problem where interacting with buttons used to turn on objects are turning off the buttons. This is usually because the program is referencing itself but it doesn't appear to be

I'm sure there has to be a better way to do this but it should work.

[granite pier]

Extremely simple script, trying to make a script where I set a target object, and then the object with the script, follows the target at all times, plus an offset.
Currently, this script does nothing, the Sphere does not change its position no matter what target I choose. What am I doing wrong?

[granite pier]

terribly sorry, simply just forgot to put on an update event that activates set position. (I am very much a noob at this)

[pallid roost]

If you havent actually passed in a object to your NewsOverlay 1234 slots they will reference the object the script is on instead. (I believe?)

so check on the actual button that you've passed those values in

[valid oar]

Isn't that what the second image is? All of the right objects have been referenced in the public variables

[pallid roost]

Oh sorry i missed that XD

[indigo finch]

Everything looks right here. it is probably something to do with the hierarchy (perhaps you deactivating a parent object or something).

That being said, this would be the 'better' way of doing it. it's notably more complicated to script though, but it gives more flexibility. You would have a script on the button itself, that tells the slide manager object, what slide to change it to.

[valid oar]

Nothing is parented to them and some of the buttons seem to to not disappaear even though the only difference is which boxes are ticked but thanks for making a better version, I'll give it a shot! I tried using a material swap prefab but it wasn't working out.

[indigo finch]

doing it by swapping out the material will be more optimal, and actually a lot easier to code and manage. Here's an update to the slide manager script that would instead just swap materials. This script will change the 1st material slot on the slider manager's meshRenderer

[sonic ermine]

Question... in Udon (using UdonSharp) how would one measure how many players are in the bounds of a trigger? I want to enable or disable an object when ALL players, not just the local one, are outside of a trigger. The idea is to change a thing behind the scenes when no one is there to witness it.

And ONLY when no one is there to witness it.

Specifically I have a system of small things changing randomly when the map loads, with a list of objects to be enabled via a random chance (and all its siblings disabled)

So I want to make it so this can run again, not on a timer, but when no one's in a specific area. (Teleported away to another part of the world)

[valid oar]

I'm sure something like that would be possible, I assume by storing the number of people that have entered the instance and then incrementing another variable when a player leaves the trigger zone, if those numbers are equal, then everyone has left the trigger zone. Of course, you'd also need to reduce that number if anyone went back into the trigger zone. I guess what I'm not sure about is how is checking that everyone is outside of a trigger functionally any different than checking if anyone is in the trigger? Because that seems like it would be easier to work with.
