Potentially attach an audio source to each player and control their sound independently LOL

#

Add voice synth and feed it strings

silent gazelle
#

How it possible to give a player option to press on button and have a full-screen overlay from the camera view?

paper plinth
#

To make a menu?

silent gazelle
#

Nope, I want to stream camera view so I need my sceen to be fullscreen of the camera view

paper plinth
#

Can you use the streamer camera that's in the app?

silent gazelle
#

Im setting up couple of cameras that the host can change between, cuz that i need to make fullscreen overlay of the "main stream" that will show the camera view

#

I have this with render texture, the question is if it possible to put this render texture full screen on the player that wants to

I don't know how desktop works but now I understand the problem lol
In VR you could have it in your field of view like a hud and switch it on and off but that's it

Gotcha, thank you

Anyone know how to destroy instantiated objects with U#?

scarlet lake
#

i found out a way to maybe get my audio to work

#

i have to setup a large collider though to surround each area

#

and when the player enters it the music toggles on

#

or off if the player isnt in that area

placid niche
#

That's kinda overkill

scarlet lake
#

its the only way i found that could work

#

as i tried making my 2d audios for music stop after leaving their circles but that didnt work

#

and i have to have them 3d

#

but

#

that makes them sound all earrapy

#

and annoying

#

compared to when they were 2d they sounded nice

#

and searching on the web has given me nothing exept that

#

is there anything i can follow to help me get the 2d audio to toggle when in certain areas?

lilac hatch
#

So, I had report of, sometimes,
Whatever the videoplayer
People not having the sound when watching streams from twitch/whatever.

It work for some in the world but not everyone, the same link work in others world.

Could it be because i'm using only one audio source ? ( Using the same on left/right since it's a 2d audio world wide i didn't see the point of having 2. )

placid niche
#

How do you destroy instantiated objects with u#

glossy hornet
#

ive got some problems with the merlin video player prefab, if u put in a twitch stream i can see the picture but i dont hear any sound. other worlds are working with sounds. i have no idea where to look at. youtube is working fine - other people in my world are able to hear the sound, im the only one

#

in terms of terrains
how many terrains can I have until the world becomes unmanageable
can I make a scale model solar system with planets and moons and stuff and reasonably expect people to be able to be at both mercury and neptune?

scarlet lake
#

it depends how big the world is

#

the larger it is the larger its filesize

paper plinth
#

huh

#

modeling the solar system seems to be a pretty established process and I have a flying ship so....I think I'll just do it and see what happens

#

how many spheres is that? you can't include literally every moon and orbit but it's probably like 100 spheres

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

tall girder
#

Is there a way to save ur skins

pallid mango
#

In general, look up the unity scripting way of doing things. In most cases, it will be the same for udon sharp, unless it involves actual VRC APIs, functions, or events, or happens to not have been exposed

placid niche
#

I finally figured it out

#

thx for responding tho

void ridge
#

Are there any good guides on using VRCPlayerApi[]? I'm getting a random player who is currently inside a volume

#

GetPlayersWithTag would be lovely, but the docs say it's not working yet

somber hawk
#

Are there any pen prefabs available for udon?

fiery yoke
#

Networking stuff is currently being overhauled. I think there do exist some, but I would wait after the networking update.

dapper lion
#

@somber hawk yes maam

tall vault
#

@void ridge You can do something equivalent to GetPlayersWithTag with:

var taggedPlayers = new VRCPlayerApi[VRCPlayerApi.GetPlayerCount()];
VRCPlayerApi.GetPlayers(taggedPlayers);
int taggedPlayerCount = 0;

// Get list of tagged players
foreach(var p in taggedPlayers) if(p.GetPlayerTag("tagname") == "value") taggedPlayers[taggedPlayerCount++] = p;

// Pick a random tagged player
var randomTaggedPlayer = taggedPlayerCount > 0 ? taggedPlayers[Random.Range(0, taggedPlayerCount - 1)] : null;
if(randomTaggedPlayer != null) {
  // Do something with random tagged player
}```
void ridge
#

I don't know C# syntax yet. But is this basically just searching through VRCPlayerApi.GetPlayers, filtering only for players that have the tag, and putting them into their own array? Because that's what I was considering doing

tall vault
#

Yep

#

That example uses one array, gets all of the players in the instance and shifts all of the tagged players to the beginning of the array

#

And keeps a count of how many tagged players there are

#

GetPlayersWithTag will probably need another function added to return the number of players there are with a certain tag so you can allocate the array ahead of time like GetPlayers needs

#

Unless they add support for lists

floral dove
#

FYI - when iterating through players, I'd recommend calling .IsValid() on each Player to make sure they haven't left the instance.

void ridge
#

Thank you, I was checking for Inequality on Null. Is that the same thing?

fiery yoke
#

Unfortunately its not, because of internal workings of Unity.

void ridge
#

Actually, I'm not finding an IsValid for VRCPlayerApi

fiery yoke
#

Its only in the most recent SDK

#

I believe its the open-beta one if Im not mistaken...

void ridge
#

Sorry, I should have asked if they're equivalent, not the same thing

tall vault
#

So a VRCPlayerApi object can be invalidated within the same frame?

void ridge
#

And yes I see that IsValid is in the notes for the beta. Maybe Momo just let it slip that that's an RC and will ship tonight 😛

tall vault
#

I would have expected it to last at least until the end of the frame

void ridge
#

What value does GetPlayerTag return if that player's tags have been cleared or never set? vrcThinking

pallid mango
#

(Aka “”)

void ridge
#

Cool, thanks

floral dove
tall vault
#

It returns null

#

For an unused tag

floral dove
# tall vault I would have expected it to last at least until the end of the frame

Yeah, I think it should be fine until the end of the frame. Was just jumping the gun a bit on spreading the word about IsValid since it fixes the issue where a Player is not null but has left the room. Also makes null-checking any object much easier since you can use IsValid to easily only fire a branch if the given object is not null

void ridge
tall vault
#

Yep

void ridge
#

Boo. So I have to nullcheck that string value before I can deal with it? 😕

fiery yoke
#

String.IsNullOrEmpty

tall vault
#

String.IsNullOrEmpty(value) should cover you

pallid mango
#

There is a IsNullOrEmpty in unity. Not sure if in Udon

fiery yoke
#

lmao

#

First :^)

void ridge
#

jeez wish I could get some answers around here

fiery yoke
#

Actually

#

maybe not

#

This might be a flaw of the Udon VM not sure exactly right now

#

Can you show the assembly that generates?

#

Im pretty sure that Udon is incappable of doing Conditional logic, because of how it works.

pallid mango
#

W h a t

fiery yoke
#

I will test that on my own now

void ridge
#

So it's going to try and evaluate that second term every time, and give a NullReference if the string is null?

fiery yoke
#

Yeah maybe

#

Again I will test that in the Graph and in U#

pallid mango
#

Oh you mean no short cutting

void ridge
#

yeah I want that shortcut 😕

pallid mango
#

Looks safe to me

#

Oh wait no

void ridge
#

This is frustrating because I avoid stringing together Branch nodes because that's caused problems for me in the past

#

But that's the only alternative to ConditionalAnd

pallid mango
#

If string is null or empty returns true, use an empty string instead of what the api returned

#

I mean there is nothing wrong with branch nodes you are going to need them if you are doing anything reasonably complex

#

That’s like wanting to code without ifs

void ridge
#

I use branch nodes, but I avoid stringing more than 2 together at once

#

I really don't know if that's the issue, but unexpected behavior is unexpected 🤷

fiery yoke
#

Yeah I think this is a major flaw in the UdonVM/Compiler, already hit up a dev about it, waiting for a response.

#

Ahh yeah

void ridge
fiery yoke
#

after narrowing it down, its completely the graph compilers fault.

#

The graph compiler does not handle conditional logic correctly. It can, but it does not, since UdonSharp does handle it correctly.

void ridge
#

It can, but it does not, since UdonSharp does handle it correctly.
this sentence does not handle conditional logic correctly I think 😛 😄

fiery yoke
#

it can (handle it correctly) since UdonSharp does handle it correctly (which is proof of it being able to be handled correctly, => but it does not.

#

It is correct. Just a little complicated :P

Officially SDK3 should only be imported into a blank new project that has never had SDK2 before

It’s not a matter of files being left behind

I was looking for something more expedient than opening a new project and exporting and reimporting everything

pallid mango

I haven’t had any luck with fixing up a project that had SDK2 run it’s changes beforehand to let SDK3 not freak out

SDK3 was not designed to clean up after SDK2

paper plinth

well I was going to change the skybox anyway

pallid mango

Best advice is prefab everything up and transfer assets and dependencies

That’s the only way I could port stuff to Udon

I'm trying to dynamically populate a song list with a script and running into an issue where there is an exception thrown when it attempts to use the value:

Exception Message:
  An exception occurred during EXTERN to 'VRCSDK3ComponentsVRCUrlInputField.__SetUrl__VRCSDKBaseVRCUrl__SystemVoid'.
      Parameter Addresses: 0x00000003, 0x00000004
  
  Cannot retrieve heap variable of type 'String' as type 'VRCUrl'

The code that sets it is just script.SetProgramVariable("videoURL", "the-url-of-video");, so that's where the string comes from. I'd pass in a VRCUrl if I could but as we discussed a little yesterday that's not currently exposed.

Is there any way to get this working?

Basically I have a big list of URLs that I want to get into my world and be able to play on screen but I don't want to manually add them all in the editor since that would take forever, so I'm trying to script the addition in some way. It doesn't have to happen at runtime, if there are ways to do this at build time instead that would also be fine.

#

Maybe an editor plugin is a good way to do this?

If I want to randomly scale something do I just use:

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

public class ObjectScale : UdonSharpBehaviour
{
    public GameObject A;

    void Start()
    {
        A.transform.localScale.Set(Random.Range(0.2f, 0.8f), Random.Range(0.2f, 0.8f), Random.Range(0.2f, 0.8f));
    }
}
paper plinth
#

It will not be a uniform scale

steady palm
#

during a test with UdonSharp, if a gameobject has the avatar prefab system, it will only globally toggle for that targeted version (eg PC for PC users and Android for Quest users). tested both systems before posting this, other game objects sync perfectly. does anyone else encounter this?

#

same goes for VRC Pickup

void ridge
#

TIL that trying to sync a VRCPlayerApi[] value breaks all syncing on that UdonBehaviour 😭

#

and causes OnDeserialization not to fire

dusk lance
#

You can't sync arrays yet, so that's probably why

void ridge
#

Thanks, I was wondering if it was part of something more general

#

Seems like the pattern is Try to sync a thing that can't be synced yet --> All syncing on that UB stops

#

I think the same thing happens when I try to sync an int16 value

cosmic pike
#

Hey, sometimes I can get stuck panning in udon. As in, all mouse movement just pans the udon graph, and I cannot seem to stop the panning, making my interaction with the graph useless. How do I detach my mouse cursor from panning if I do not wish to continue panning? I've tried the escape key and reloading the graph but I've not had much success.

#

Disregard -- it seems that the deletion of a script is what made the whole udon thing stuck. Udon keeps the node graph open even after it gets deleted. I'm guessing that's what broke things.

manic yarrow
#

I've made the teleport script work with triggers now, but how would I preserve player rotation? right now, it uses the rotation of the teleport target.

glossy sky
manic yarrow
#

I just need to figure out how to preserve player rotation

glossy sky
#

You could try getting the tracking data of the head.

#

So your variable that's target can be the bone tracking for the head instead.

manic yarrow
#

I need the target variable so I can choose a gameobject to teleport to

native estuary
#

Remember to also make sure the player entering the trigger is the local player otherwise you will be teleporting all the players in the world

manic yarrow
#

I know I should get rid of the local rotation thing, but I don't know what to replace it with

manic yarrow
#

I use this same script for some other teleports

native estuary
#

Well but that would still happen to everyone

manic yarrow
#

I've seen it work

native estuary
#

Enter trigger player happens when any player enters it, so if one player enters the trigger it's gonna run that code for everyone

#

I mean sure it works if you do it right

glossy sky
#

I'm pretty sure it's local because I use it to teleport players to different sections of a map.

#

Okay yeah, I stand by my statement. OnPlayerTriggerEnter is local.

native estuary
#

Well unless they suddenly changed it it's not

glossy sky
native estuary
#

Well yeah because they have it setup to only teleport the right player 😔

#

Just changing the event in the above graph would not

manic yarrow
#

I've just tested with 2 clients and it seems to work

native estuary
#

Can you show the graph you have right now?

manic yarrow
#

All I've done so far is use a popular teleport script and replace the interact node with a trigger node

glossy sky
#

This graph is for another map I'm making but it's local.

manic yarrow
glossy sky
#

Also Fiji, for your target. That's wher eyou plug in the bone tracking data.

manic yarrow
#

I know I need to remove the Transform Get Rotation node, because it's using the rotation of the target gameobject

glossy sky
#

You don't need the "NetworkingGetLocalPlayer", you can just hook it directly from the OnPlayerTriggerEnter.

#

Here, I'll make the graph quickly for you.

manic yarrow
#

at least on my version of the SDK

glossy sky
#

Errr. Update your SDK then because it's local now.

manic yarrow
#

wait no, I updated it the other day

#

what should I do instead?

glossy sky
#

Then yeah, you don't need the extra node.

native estuary
#

Oh yeah never mind I'm just too tired and was thinking about it completely wrong

#

You guys are right

manic yarrow
#

just delete it?

glossy sky
#

Yeah then connect the "VRCPlayerApi" that's on the trigger event to the instance instead.

manic yarrow
#

ohh, makes sense

#

let me try that real quick

native estuary
glossy sky
#

This is how you preserve the rotation.

#

So your position would still be whatever you set your destination to be.

manic yarrow
#

wouldn't the tracking data include ALL rotation?

#

I wouldn't want it jerking someone's head around

glossy sky
#

Jerk their head around?

manic yarrow
#

if you're getting the rotation from the bone data and setting it somewhere else, wouldn't it change where they're looking?

#

or am I just thinking weirdly because it's late? 😅

glossy sky
#

It's not being set somewhere else. All you're doing is getting the rotation.

#

The "TeleportPoint" in the example dictates the destination. Only that.

#

So if I'm looking South for example, the bone tracking would be South. That's dictating how you end up rotation wise.

manic yarrow
#

For context, I'm using this on an endless stairway

#

so the smoother I can get it the better

glossy sky
#

Yeah then, there's no difference. Your orientation is remaining the same.

manic yarrow
#

I want someone to be able to walk through at any angle and not know they moved

glossy sky
#

Exactly. So you want to move their position, but you want the rotation to remain the same.

#

That's why you want to track the head instead to retain the resulting teleportation rotation.

#

I understand what you mean about quaternion tracking all rotations but unless you're in a chair, your orientation shouldn't change aside from you looking south, north, eat, or west.

#

Reason being is because it'd remain Scene Up.

manic yarrow
#

That doesn't seem to have worked

#

Whenever I teleport to the destination gameobject, it faces me forwards relative to the gameobject

glossy sky
#

Mm. Let me go open up my Unity and I'll see if I can get it working for you then.

manic yarrow
#

Wait

#

is it because I have it on instance instead of head?

#

you mentioned earlier about tracking the head

glossy sky
#

It should be like that.

manic yarrow
#

never mind, can't actually set it to tt

#

I can't see any glaring differences

native estuary
manic yarrow
#

Still does the same thing

glossy sky
#

Oh I'm stupid, yeah, you don't need to track the bone at all.

#

I forgot that exists.

manic yarrow
#

wait, I'm just dumb

#

it's because the place I'm teleporting to isn't facing the same way

#

is there a math node or something I can use to save myself the hassle?

#

Never mind, it's not that either

They won't loop - the graph ...

I've put a scrollview with buttons on it, which send an interact event to a script on click. When I was using it in VR yesterday it seemed really flaky in that sometimes you had to click it many times for it to work. It almost seemed like I had to get really close to it but even that wasn't reliable. On just PC it doesn't seem to have this behavior.

Is this a known issue or is there some other way I should set up buttons to have it be more reliable?

@dusk lance Just moving the conversation here since it's primarily Udon, but can you wrap your head around that video you showed me? I'm struggling to figure out where I should position the child objects and such.

dusk lance
#

Now I need to watch the ending of it

manic yarrow
#

As it stands, I get stuck in a teleport loop back and forth between 2 triggers

#

I have 1 trigger at the top of the stairs that should send me down, and another trigger at the bottom that should send me up

dusk lance
#

So, with seamless teleport, if you put the trigger in the exact same location relative to the other side, then you will obviously be inside it when you teleport.

#

What you should probably do instead is move the collider .2 units back from the origin.
In the video, he has only one trigger collider so he never ran into that problem.

manic yarrow
#

hang on, I'll take a screenshot of it so you can see what's going on

dusk lance
#

I have an idea, just hard to explain without a diagram

manic yarrow
#

So in either direction you go up or down 4 flights and get sent to where the other trigger is

#

Hopefully that helps

dusk lance
#

Hmm, move the red cubes further apart maybe. Have the top one be closer to the top of the stairs and have the bottom one be closer to the bottom of the stairs. By doing this, you will have less chance of player entering the other collider after teleporting.

manic yarrow
#

Where would the child objects go?

dusk lance
#

Child objects should auto move, so it doesn’t matter.?

#

Oh, the other origin needs to be at the same location as the collider, but at the other end of the stairs where you want players to end up.

#

I would say turn off one system and just focus on getting one working for now.

UB is not doing any syncing or firing OnDeserialization again, only big difference is that I tried syncing the VRCPlayerApi value directly rather than pulling out the PlayerId integer and syncing that

#

Yep. Disabled sync on that variable and now I'm getting OnDeserialization as expected. Boo. Back to the int.

floral dove
#

no, VRCPlayerApi can not be synced. Stick to basic types - bool, int, float, etc.

You should be able to just make the gameobject itself the variable and get the component off it

When is Start() called? I need to do something when a player joins the world

#

need to sync things with late joiners

dusk lance
#

Currently start is called on the first update when networking is ready. This does not mean variables are synced. You can also try with OnPlayerJoined and look for the local player.

void ridge
#

hrm

#

Yeah, it should be emphasized that "networking is ready" means something pretty narrow

#

I'd really like an event that only fires when networking has started and everything that needs to be synced "should" reliably be synced

dusk lance
#

Let's hope the networking update has that

void ridge
#

I acknowledge that that's a very scary "should" and probably a super complicated thing to ask for

#

As it is right now, I'm just starting a timer for ~8 seconds after Start and calling that good enough for all scenarios including the worst

dusk lance
#

There is a more reliable way than waiting 8 seconds, but I'm not sure if you want to dig into checking if a variable changed in OnDeserialization.

void ridge
#

Oh no that sounds just like what I need

umbral hearth
#

@lilac hatch you can sync your own repo with Git, you can use Unity Collab for in-editor, easy to use features (limits on team members and file size), or Plastic SCM as a more fully featured integrated unity collab tool. The Devouring was done with 4 members on a paid Teams Collab account. Since then we have been demoing Plastic, for beginners, I’d say Collab is easy as long as you do not work on the same scene at the same time. Communicate pushes and pulls.

dusk lance
# void ridge Oh no that sounds just like what I need

For OnDeserialization, this will be called on all clients other than the owner. You can create a duplicate of your synced variable that is unsynced and has the same initial value as the synced variable. In OnDeserialization, you compare the values between the two. If they differ, you know the value has updated. You set the duplicate equal to the synced, and then perform any logic for that variable being changed.

Is there any reason y'all know of as to why video played with AVPro would have audio on PC but not on Quest? There isn't any quest specific configuration I have for quest for it. But when I just tested on Quest the video itself still plays but there's no audio.

I bring up AVPlayer specifically because it worked fine yesterday with the other and this was my first test of it on Quest

umbral hearth
#

Is it synced?

#

Synced video doesn’t work on quest afaik

scarlet lake
#

Why doesn't synced video work on a quest?

somber hawk
#

Yeah yesterday syncing worked just fine with the Unity one, I haven't tested syncing yet with AV. But for this test it was just me trying to play it for myself and there was no audio

void ridge
#

Hmm actually also adding a node to set syncReceived to true for the owner-only top part, that way if ownership transfers the old owner won't fire that event

dusk lance
#

I'm going to say yes, but I'm only hesitant because I'm not thinking through your "not equal" logic. I probably would have set it up more general, but in this case, you know that the value will be true and you don't need to set syncReceived directly to syncedData.

void ridge
#

Alright, but I think I get the basic idea that you can get a reliable event by executing a flow on the first frame a synced value differs from its default

📎 unknown.png
#

Only problem is I'm not really sure if this is a proper way to address the IsUserInVR delay, which is the other thing I'm using the timer for

dusk lance
#

Someone recommended checking during OnPlayerJoined.

#

I haven't tested if that works

void ridge
#

It wouldn't if you were the first to join either, would it?

dusk lance
#

If you don't want a timer in this graph, you can also use my TimerQueue prefab in the database.

void ridge
#

Because that only fires if there's a second person connected

dusk lance
#

You can send it events with durations and it will automatically call it. It can handle any number of running events too. (I think limited to 1024, but that number is arbitrary)

dusk lance
#

Otherwise I would need to "fix" CyanEmu behaviour

void ridge
#

I could easily be wrong

#

So if you load into a new instance, all by yourself, one of the first things you do is fire OnPlayerJoined for yourself?

dusk lance
#

Yes

void ridge
#

OK, I accept this.

wanton oxide
#

OnPlayerJoined gets called for each player in the instance, starting with the local player, then counting up from lowest to highest playerID

dusk lance
#

Pretty sure you aren't guaranteed the order of on player joined, but I haven't tested that in awhile

wanton oxide
#

so if you join an instance with people in it it will still first call the local player and after that all the other players

#

the order is fixed, its in order of playerid

#

with the exception of the local player

#

which you need to handle

void ridge
#

So the theory is that this would give me whether the local player is in VR? I'll try it out

#

If that doesn't work I think I'll use the method of saying
auserwho'sinVRsayswhat? really fast

#

Oh and thanks for the tip on your TimerQueue Cyan, I'll use that for other stuff if not this

dusk lance
#

My timer queue uses U# as a heads up. I made the graph version over a year ago, but it broke completely because we still can't have UdonBehaviour arrays. I'm pretty sure it has an example that uses graphs so you can see how to use it.

I'm going to be honest, last time I got something like this I just evacuated ship, created a new project and yoinked all the assets in there, somehow that worked since removing individual parts of the project didn't fix anything.

It's an option if you can drag in most of the assets.

Maybe make a prefab.

I'm trying to figure out how to move something in the direction of input.

float z = Input.GetAxis("Vertical");

// If not holding anything return forward

    z = 1;

return new Vector3(x, 0f, z);

This works but is in world space. How do I make it relative to the player rotation? I can't use transform.forward from the player transform as far as I know. Or can I get it somehow?

You'd expect them to be the same.

collider.name should return UnityEngine.Collider(GameObjectNameHere)

Hi,
If I want a slider to sync what position it is on between all players, Do I just add a udon behvior: Sync ?
The value is currently being synced by ownership, But I also want the slider to sync so everyone sees the slider at the same position

unborn hornet
fossil thistle
vast locust
#

Add empty udon behavior - sync position ?

void ridge
unborn hornet
#

Its more complex than that.

#

What joker said.

void ridge
#

networking = hard

fiery yoke
vast locust
# void ridge networking = hard

If the world already has many networking components, Would it be better to just ignore this and not have it sync position?

void ridge
#

That's a design decision, i.e. it's up to you and what you think your world needs 🙂

vast locust
#

I was thinking of networking performance

unborn hornet
#

Basically, you need to update the slider value during OnDeserialization, but the thing is is that when you change the slider value, it implicitly triggers the onchange triggers, which since the on change trigger is already doing the variable update. It basically loops and can cause race condition problems.

fossil thistle
vast locust
#

HMm, Or maybe it will be better to be able to send a custom event,
So when someone grabs an item, It sends the ownership command to the slider,

Could that work?

#

I'm just trying to make it not confusing for the players

void ridge
unborn hornet
#

It's UI. I helped them with it previously.

paper plinth
#

Joker did you see my walkable blimp?

vast locust
#

Example:

15 people in world.
1 person plays the game, Changes the value to fit their play style
Then next person plays, And thinks the value is still on their previous spot, But since ownership changed, the value of the object changed?

paper plinth
#

That wasn't hard to convert to graph

vast locust
#

So let's say someone grabs the "GUN", Then it sends "OnSlideUpdate" towards the slide so it updates the ownership

Would that be possible?

#

I am currently assuming that every object has it own Owner and not that everything in the same world shares the same ownership, Is that correct?

void ridge
vast locust
#

I think I might need to rephrase what I was tlaking about above

Networking.SetOwner, Is that for all objects or just one specific object?

When do you need to use [SerializeField] in UdonSharp? I see it in lots of examples but I haven't been using it and things seem to work fine?

fiery yoke
#

It tells Unity to serialize a field even when its private. Which means that the private field will show and be editable in the Inspector.

#

By default all public fields are serialized.

dusk lance
#

[SerializeField] private var
And
public var
are the same in U#.

fiery yoke
#

Not quite

dusk lance
#

Pretty sure there is no difference in the assembly, but I could be wrong in that it actually does modify the default values

#

I haven’t actually checked.

fiery yoke
#

Mechanically yes. However while in the C# environment private vs public still shows intent and lets the IDE know what is and what isnt acceptable to use by your standards.

dusk lance
#

Okay... intent is one thing for code readability but functionality is another. My comment was for functionality, meaning others can still modify the variable.

fiery yoke
#

I would still argue that showing intent is valid enough of a point to say that they are not "the same".

#

But yes there is no accesibility restriction regarding variables in Udon

#

all variables are public inside the VM

somber hawk
#

Thanks, why would someone to opt for private+serialize instead of having it be public? So other scripts couldn't access it or something?

#

Oh I see you mentioned intent above which is what I'm referring to 🤦‍♂️ . You at least signal you probably shouldn't be trying to use this, but it might be nice to have in the editor to easily tweak config

fiery yoke
unborn hornet
#

My understanding is:
[SerializeField] private = you don't want other classes to access this but you still want it to show up in the inspector
[HideInInspector] public = You DO want other classes to access this but you DON'T want it to show up in the inspector.
private only = no external access and not shown in inspector
public only = external access and shown in inspector

Obviously as mentioned the access levels aren't a thing in the VM, they only matter for the C#/U# compiler phase.

fiery yoke
#

Thats the long answer yep.

#

However there is also a minor difference between [HideInInspector] and [System.NonSerialized] but anyway

probably you either have a lot of synced pickups or other synced objects that the master has to do a lot of network processing for, and/or have some heavyweight udon script that runs only on the master. The latter might be visible in the unity profiler, depending on what exactly it's doing

you drag the object into the field in the inspector

"transform" moves the position of whatever its on

then use box.transform instead of transform

Position is relative to the world's center (0,0,0), localPosition is relative to the parent transform center.

If you want to match the inspector you need to use local in udon

Local everything, but yes

Maybe it will be better if I set a world position instead of local postion since the parent can move but I want to reset just the child object.

However I can't get either local or none local to work

#

Am I missing any functions to get it to worK?

pallid mango

If you want to move a child directly on top of its parent, you set local position to 0 0 0

In general you want to deal with local space otherwise programs will break if you relocate stuff in your scene

fiery yoke
# somber hawk I'm doing this in UdonSharp, is this considered bad for performance? I don't nee...

Ew lightmode...But seriously, you kinda have to run it on Update. The best way known to me to make something happen only every x seconds is to use an accumulator in Update that checks against x. Which would be a micro optimization if it does not need to run every frame...but probably not a point you should even consider. Udons performance isnt great, but its not bad to the point where you need to reduce every single assembly instruction to a minimum.

somber hawk
#

I assume that continually setting it to the same value probably isn't actually thrashing the UI

fiery yoke
#

There is some considerations with how to do UI stuff, but nothing that will drown your fps (on a low level).
It would ofcourse be best using Event-Driven Programming where the Video Player has some event that lets you know when it has progressed further like OnNextFrame or something like that, but unfortunately thats not a thing.

cunning mist
#

What's the Player variable a reference to? If it's possible to avoid it, Null checks can be pretty rough performance-wise.

pallid mango
#

There is also FixedUpdate to update in a slightly less frequently :)

fiery yoke
#

FixedUpdate is not meant to be used like that

#

FixedUpdate is meant to be used for updates that need to happen at a fixed time interval, like physics calculations.

somber hawk
pallid mango
#

In the case of checking for a null player, I don’t think it makes sense to check far more often just because the player has a higher framerate

Maybe I’m wrong but I’ve been using FixedUpdate for anything I want to be “framerate independent”

Ok I have a issue I don't understand at all.

I have a cube

[] - Scaling on this cube is .5 on X Y Z

I add another Cube as a child to this cube, It gets scaling 1.0 since it's a child,

I then modify the Cube scaling on the Parent cube [] to scale with a slider.

Since the parent and childs have different scaling (0.5 & 1.0), They scale differently with the slider.

How can I fix this?

However only the parent cube scales correctly, Child cubes scales is off, Their like half the size of the parent cube, But in the inspector (When scaling) they say they are the same size as the parent cube

children will scale proportionally when you change their parent's scale

no, this should only be needed on the parent cube, all the other cubes should scale proportionally.

#

Hm - I recreated your code in the graph and it works as expected here, perhaps you have something amiss in your setup?

Hmm let's see

#

Are these cubes added to a parent or are one of these cubes "The" parent?

Also, this wouldn't cause your problem, but you could save checking every FixedUpdate by using OnValueChanged to fire an event instead like this:

quick question is there a sync for a world. "example i make a door lock using globe hierarchy to turn off the doors so people won't click on them" is there a way for it to sync for people that coming after when the door been lock?

I'm really sorry if this is the wrong place to ask, is there anyone here who would be kind enough to help me with a problem I have? I have been working on a world it works fine when I build and test in unity. I then uploaded it which worked, but when I try open the world in VR chat it fails and just drops me back to my home world. I'm going a bit crazy trying to solve it so any help would be really appreciated.

Is there any way to glean more information out of a "Video failed: theurl" log from the default player?

I'm working on it's transferring ownership and there seems to be some sort of issue where after I transfer ownership a few times, it says "video failed" on the non-owner and then "playing video" (the one that failed), but it actually plays the previous video

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

I'm having an issue where when teleporting a player, instead of the player moving to the desired location they move into a wall

#

the target location is here

unknown.png
#

original location is below it, inside a room

unknown.png
#

i'm using a reference to the Transform (its an empty gameobject) like this

unknown.png
#

Teleport is definetly getting called correctly because the player is moved but yeah the player isn't moving to the correct location

#

after messing with it for a while more, seems like its only moving in the X and Z directions but not Y?

#

can a player be teleported upwards?

void ridge
# wanton oxide can a player be teleported upwards?

Yes, of course. Are you sure this is an empty gameobject? Might it be that you're looking at the handles and inferring the location, but those handles aren't on the actual pivot of that object? That's a mistake I've made.

#

Also, is this Udon or SDK2? The stuff in that last image doesn't look familiar to me

wanton oxide
#

its a custom script

#

it does quite a lot of things thats why it may look weird

it can toggle gameobjects, pass information to some other function and teleport a player somewhere

scarlet lake

And if you are making a custom mesh you need to make sure the mirror mesh lies on XY plane in the mesh renderer's local coordinate system, and its facing direction is negative Z axis in local coordinate system

#

turns out, you can teleport a player from within Interact() but not another function?

#

Idk, this shit is really weird, the thing that broke everything was me adding a delay to actually teleporting the player since having an animation on the button looks nicer

placid niche
#

I cant seem to find the proper way to delay something using deltatime

#

anyone..?

dull stream
# 
float delay = 3f
float timeLeft = 0;

void StartTimer()
{
  timeLeft = delay;
}

void FixedUpdate()
{
  if(OnCooldown())
    timeLeft -= Time.fixedDeltaTime;    
}

bool OnCooldown()
{
  return timeLeft > 0;
}
#

If you're using udonsharp

paper plinth
#

@placid niche you can use a float * delta time to get a value and add that value to a float counter. Then use a branch to gate your payload that's true when the float counter gets over a certain amount. Don't forget to reset the float counter when the payload drops.

dull stream
#

I think it's better to remove than to add

#

as in count down from a value to 0 instead of up

#

that will prevent you from having an issue somewhere that ends up with the value counting up to crazy amounts

placid niche
#

@dull stream completely off topic but are you the one that made pumkins avatar tool?

Anyway thx guys I'll mess around with it

dull stream
#

Thanks vrcAevSlap

#

But then again it can count down to ridiculous amounts too

#

Still, i find count downs and comparing to 0 to be easier to wrap your head around

paper plinth
#

There's plenty of ways to jack your stuff up, to be sure lol

#

I use up counters because I learned most of my programming on rslogix in context where we used the counters for other stuff too, and the counter functions were super robust, so you just get used to doing things a certain way and you don't think about it.

#

Almost everything else I do counts down to zero lol 🤷‍♂️

dull stream
#

I used to do it like this too when doing scripts for csgo

#

But I would also have a cached variable for the now time

#

Which, as you can imagine, got pretty big

#

and the target time was = now + delay

paper plinth
#

Idk how to feel about it but once I took the now time as a variable and added five seconds and used that compare to set a bit high.

#

For some reason nobody does that

#

The system clock is used for friggin everything in a plc

dull stream
#

I mean, you're probably not gonna run out of memory with one big number lol

#

But I like small count downs

paper plinth

That's another thing I don't really understand about how memory works in a PC and why you use time for some things and not others. I just try to follow the crowd.

I want to just create a situation where it knows if a player has entered a collider, and if so it does something!

paper plinth

If I remember right, to make a teleporter, you want a collider set up as a trigger and then onplayertriggerenter with a branch to check if the player islocal, and if true, teleport to, the player (drag the noodle from the onplayertriggerenter event) and you destination position and rotation, and sometimes people put a gameobject in the scene in the right place and rotation to represent that and then drag it into their graph editor and get the transform position and rotation off that. You can also public it and set it in the inspector.

So I guess the answer for now to sync everything is to create an entrance lobby to the world that has a button that needs to be clicked with a teleport to the main area of the world, that includes all of the animation sync variables and a 'check' to set them all correctly so everything is correct when someone enters. This is a heck of a lot of hassle and work to get around the check box that is greyed out. I sure wish we had at least a hint of a timeframe on when 'soon' is... Oh well I guess I get more experience this way at least.

If youre syncing a string then its probably too long

Hm, there shouldn't be anything long. Is there any way to get more information about what is exactly is causing this? I'm working with a (now modified) version of MerlinVR/USharpVideo

fiery yoke
#

Well as far as I know it has to do with deserialization of network data

serene moat
#

you probably have a URL that's too long

#

can't really do anything about that other than shortening the URL

#

you only have ~70 or so characters you can have in a URL before sync starts dying

somber hawk
#

My URLs are pretty short, example: https://karaoke.constarr.com/yt/XVG-jODTeyQ

Is there such a thing as too many synced variables on one game object? I've added more to this than the standard ones, nothing crazy, but things like song artist/title which are also still fairly short

serene moat
#

yes if you add more synced strings on the same object you will quickly run your limit out since the limit is shared between all synced data on the object

#

I don't recommend adding any synced strings to the video player itself, if you want to sync more strings you should move them to other udon behaviours

somber hawk
#

Funny enough I initially had these on another object when using the default graph based player, but I wanted a code based one so I could modify it easier 😂 Looks like I'll have to reintroduce the other now but that's not too bad

serene moat
#

the sync limit should improve with the manual sync update whenever that gets released so we hopefully won't have issues with URL's being too long. I'm going to be moving the video player to manual sync since it really doesn't have anything that needs continuous sync

somber hawk
#

Moving that state to another object resolved it 😅 thanks for the help!

Do debug logs have any effect on uploaded worlds? (assuming they aren't intensive to calculate the values provided)

So there's that dealy where if a player hits a collider and you try and run code on collision it just stops the Udon behavior. I've been avoiding it by using layers so the player doesn't collide with said objects. But is there a way to start the collision code so that it detects it's colliding with a player and stops instead of crashing the behavior forever?

#

I suppose more precisely it's when you try to grab the object that collided

floral dove
#

Hm - our intention is that Players should not show up in normal collision events but only the playercollision events. However, maybe that's only true for the player collider and not for other colliders?

twilit breach
#

oh the ragdoll can still collide

floral dove
#

the extra colliders added from SetupCombat?

twilit breach
#

So my specific case is that I have mining node that grabs strings on collision and checks for "pickaxe". They don't detect players or crash if i walk into them or touch them with the colliders attached to hands from combat setup. But if the player dies and their ragdoll touches the node then it crashes.

#

on player death does the layer for those extra colliders change?

floral dove
#

I'm afraid I don't know, it's possible but I haven't looked at our ragdolling system at all

twilit breach

That's understandable, I recall its officially unsupported atm so its to be expected

I'm trying to build a switch that goes between 3 states but I'm running into an issue where it works in Unity but not in VRChat... It uses a springjoint attached to a sphere, and ideally the script takes a vector3 value for each of the 3 states and applies that to the connectedAnchor property of my object's springjoint so that the sphere "boings" between 3 different positions. I can press play in Unity, manually change the Connected Anchor, and see the behaviour I want, but I don't see it in VRC.

twilit breach
#

How does your Udon behavior look. It seems that it's not properly changing the Connected anchor to the new vector 3 through Udon, but without your code its hard to check

dusk lance
floral dove
#

we check if the 'other' collider is on the Player's gameobject. If it is, we divert to the PlayerCollisions (in Udon only)

dusk lance
#

Hmm, it would be nice to know if it was the actual player capsule vs user collider. That was a major issue with the devouring but still doesn’t sound like a good solution exists in udon yet. Then again I haven’t tested ¯_(ツ)_/¯

hardy crown
#

I made an empty gameobject with just a rigidbody, set it as the "connected body" of my sphere's springjoint, and set the empty gameobject's transform instead. That works for some reason.

setlocalposition.JPG
#

Shouldn't these two things, functionally, do the same thing though?

twilit breach
#

Could you post an image of the hierarchy? I'm still a little hazy on your specific use case but sometimes you have to set the connected body to null, change the anchor vector, then re-attach.

#

and if game objects are getting set active and inactive it can mess with the anchor vectors at runtime

#

and also for some cases you want global vector coordinates and other times it needs to be local in regards to the parents

hardy crown
#

In both cases they're both children of the same parent object, in the first it's a stationary object. The script is a component on Control Sphere, as is the springjoint

plinthactivate.JPG
#

In the first case I had Cube as the Connected Body and I was trying to change the Connected Anchor vector3 as a means to move the Control Sphere object

twilit breach
#

whats is the value of onRelative vector 3?

hardy crown
#

I tried a couple of different values

#

Sorry for being obtuse here, I'd be more specific but since I figured out how to get it to do what I wanted I've kind of lost track of what the state was where I had the problem

twilit breach
#

If I'm visualizing it right in the first case you are setting the connected anchor to a vector 3 based on the scale/parent position of cube (since it is the connected body), and in the second case you are using the transform of a new object that is also a child of PlinthActivate so you are using Plinth as the parent for local position reference. But if it's working now I suppose it should be fine

You need to put a Branch node between OnPlayerJoined and the first execution, and control that branch with the bool output of get IsLocal

Output the True execution to your timer program, and False should connect to nothing. Then it'll execute only for the local player joining.

Hello,
I was working on some advanced items in my world but realised when I wanted to show my friends that the scripts ofcourse all are client side.
How would someone go about making a function happen on the server side?
( im a educated game-dev with a degree. so give me all the information you have. )
normally i would use photon2 for my networking but as its vrc and I cant even parse a integer to a enum. dont think i can do fun stuff

( I use udon-sharp btw), thought It would be good if I clarified

somber hawk

how would one, go about making a customnetworkevent in udon sharp. Do you have any examples I can refer to?

somber hawk

I don't think it's any different than normal events in Udon

fathom stratus
#

thanks for the help will look into it further with use of the information that you have send me.
As I am not very familiar with the use of Udon yet as I do not really see any connections or similarities with networking plug-ins like photon 2 that I normally use for my game programming so might take some time for me to be able to make some cool stuff in VRC but now I am just trying to try to recreate some complicated functions that I use quite frequently during my programming.
But as the udon networking is based of of photon 2, should be finding some similarities soon

But I would like to thanks you once more for the information you have given me an responding so quickly to my question, and I wish you a very nice day.

# fathom stratus thanks for the help will look into it further with use of the information that y...

VRChat uses a (probably) heavily modified version of PUN. Their networking architecture is very similar to that of general P2P, however the data goes through a middleman (the Photon Servers). Currently Synced Variables or some behaviour are serialized by the networking owner of that behaviour every "network frame", send to all other users connected to the instance/room and are then deserialized there. There are two events called "OnPreSerialization" and "OnDeserialization" relevant for this. Note that serialization only takes place when two or more users are connected to an instance. Network Events are essentially named RPCs. They are sent from an instance of an UdonBehaviour component to the corresponding behaviour on a remote client. Thats pretty much all there is to know about the fundamentals of VRCs networking.

#

Ohh and networking data is badnwidth limited, per-variable and per-behaviour and there is an absolute global limit across all behaviours.

You can with animators (I think they can control world lighting). Have the button interact set an animator boolean. Alternatively, if you want it to be global, call a custom network event for everybody that sets the bool.

Can someone point me in the right direction for an example script to make toggle-able objects be in the same state for late joiners, as it is for everyone else in the world. I assume that a 'button' must be clicked when you enter the world, but I haven't a clue how to implement that.

dusk lance
# long fiber What is the best way for waiting some amount of time? I'm making a cat and need ...

If you check the udon section prefab database (vrcprefabs.com/browse), I submitted something called the TimerQueue. It allows you to send it any number of events and durations and it will properly wait that duration before calling it. It requires Udon sharp though. (I really need to remake it in graphs again)

If you would rather make the logic yourself, you would need to create a variable that represents the time for your event and check in an update loop until that time is reached, and then call your event.

dusk lance
# tribal meadow Can someone point me in the right direction for an example script to make toggle...

There are two ways to do it, but it depends on how you are handling it for people in the instance. If you are using a synced variable, then it would be the same for late joiners as it would be the people in the instance. You can see a graph example in the example scene. Check the ToggleSync graph and UI Toggle example.
For non variables, this means you are using network events. On click, someone sends the network event to turn on or off the object. You can handle this for late joiners by having master check on player join and then sending a network event based on the current state of the object. I don't know if there is an example of this approach though.

OK, I've been using the network event method so maybe I'm approaching this wrong (didn't know this could be done in a different way) What I'm trying to do is basically have a trigger object, that works as a teleport, to simulate a 'locked door' when the door is in the locked position, the trigger object is removed, when it is unlocked, the trigger object is present. The problem is when someone joins the world, the default position of the trigger is on, even though it's off for everybody else, so I need this object to be in the same state for everybody.

Can anyone help me work out why player.GetPosition() is returning seemingly random numbers?
Testing with Cyan Emu, but the issues seems to persist in VRC too.
Numbers only change as I move around, and moving along just one axis (by moving against a wall) all three numbers change
obj.transform.position = player.GetPosition();

The object does have parents, none of which are moving

#

The numbers there are the rect transform that I'm trying to update with the player's location, looking at the object while in play mode

#

I am adjusting the transform a bit:

        return new Vector3(-newPosition.x, newPosition.z, 0);
#

had some of the coords around the wrong way, but numbers are still wrong

Is there a way to set the local position?

That was the source of my problems, thank you. Workingoutside of visual studio is making API discovery tricky, easy to miss things

SDK3 Question: I know you can do it with SDK2, but can you have a post processing weight slider in SDK3? is it done differently?

hey, is anyone willing to teach me how to use udon scripts (such as triggers)? or atleast send me a tutorial. i already know how to make pickupables btw. (using 3.0 sdk)

is there a way to make this udon script only fire for local players? it's basically someone entering a cube, which enables a mirror, but right now it enables for everybody instead of local

Take that player output run it trough the VRCPlayerApi->get IsLocal node, and input the resulting boolean into a branch.

Thank you! Works!

Has anyone tried harry's pool table in an 80 person room? is it just a recipie for network lagging everyone?

Is there a method to communicate the state of a variable outside of VRChat? I have a boolean I need to save as either true or false when I leave the world.

I have added Sound Source and VRC Spatial Sound Source and when play Sound Source in Udon while running Game in Unity it works but in VRChat test it does not. Did I miss anything?

Try cranking up your in-game volume settings, and turning up the volume of the Audio Source component? (pls test this before publishing it)

Hm, thanks. I will try

# dusk lance There are two ways to do it, but it depends on how you are handling it for peopl...

I'm still a bit confused, I'm looking at the examples, and I'm not completely understanding what these scripts do, or how they would be implemented...all of them are related to a checkbox? on a UI panel...I'm not sure how I would use that for a toggle button.... in a nutshell, all I'm trying to do is have an object toggle button that turns the specified object on or off (there or not there) and have it so everybody, regardless of when they entered the world, has it set the same way. I guess i am not fully understanding the back end of things and why this is such a difficult thing to achieve :)

#

The purpose of this is to remove a teleport collider to the back (control room) area of the world, where I only want those operating things to have access, and to prevent 'just anybody' from being able to access these controls (stage world)

I removed the Get IsLocal for the turning off portion, seems to do what I need now

Haiai, I have a Udon question,
Is it possible to make a toggle to activate or deactivate a script that I have placed on a GameObject?

Example: Script is disabled, With a toggle on a button, It activates the script,

Pressing the button again would disable the script

U#

tribal meadow
#

The way I've done this is attached the script you want to toggle on and off to an empty object, that way when the script is run you don't see what it's attached to, but it runs the script.

Pefect, Will do that, THanks

Does Udon or U# support the in-code modifier to the culling mask of referenced camera?

How can I make a slider that controls the amount of Post Processing in Udon?

#

The slider has to control an animator's variables which the animator then modifies the post processing stuff.

I thought I saw some code documented, but I can’t fully recall 👀 I will try to remember to check today

fiery yoke
#

Yeah there is some

but its not well advertised and last time I checked it was very sparse. (which is probably why its not well advertised)

Yeah that’s what I saw too

Is it possible to detect hand touch? Like player trigger for hands only?

paper plinth
#

I got to the point where I compare the player hand bone position to the collider bounds and that's as far as I got

#

If the position of the hand bone is inside the collider bounds, fire the event. It didn't fire.

#

ok

thanks

hello, how do i use events with udon?

#

what i need to do is that when i click a button, it will run code in the parent

ornate sky
#

do you guys know how to import an emission cycle material from blender to unity ?

#

@edgy slate i think in the add event you can put a script, like c# script

edgy slate
#

add event where? i don't see any add event. it's asking for the name of the event

long fiber
#

Is it possible to get Intellisense in Udon Sharp? For Udon and VRChat classes

#

maybe some dummy libraries?

paper plinth
#

Or

#

Send custom event

#

If you need to have it to be event driven

edgy slate
#

i want to do a keypad to have a portal only appear if i type in the combination basically

#

i'm not sure if it needs to be event driven

#

are program variables spread through the whole code?

fiery yoke
#

No. They are per behaviour

edgy slate
#

is it possible to detect a pressed interact in a different object? that would pretty much solve everything

fiery yoke
#

No, you would send a custom event to the interested behaviour

edgy slate
#

ok, I think i only need one more thing. how do i receive the custom events in udonsharp?

Could someone help me consolidate for the following stuff?

Udon Script Variables:
walkSpeed
runSpeed
StrafeSpeed
(is there a crawl/prone Speed? I'm only looking at the Example World atm)

Desktop controls:
direction arrow walking
crouching speed
prone crawling speed
left-shift (speed multiplier? it can be used while both walking and crouching)

Keyboard and Mouse VRChat Doc:
WASD | Player moves *
Z | Crawl
C | Crouch
left-shift | Sprint

Locomotion Controller Standing blendtree and proxy_animations:
walk
run
sprint (only forward animation and forward blendtree option is present)

#

.
I'm only interested in Desktop at the moment, I know with VR, the crouching and prone is slotted into automatically depending on how high or low the player's headset is while playing.

# floral dove what is it that you're trying to do?

What is Sprint? Is it when I am holding forward and holding shift? Or is that just Run? If the latter is correct, what is the Sprint animation and blend-tree option at that and is it ever used? (ie can I just not animate for it since it is unreachable)

What is Crouching + Shift? Since it's faster than just holding movement while crouching, does that mean that it's not "Sprint" as designated int he web Docs, but is actually just a speed multiplier? Does that also mean I could figuratively have a while set of crouch_run animations that would be seperate from crouching?

#

I'm trying to understand lol, and animate and be consistent with the existing VRC build.

this channel is for questions about Udon, our world scripting system

pastel kite
#

Okay, thank you. I encountered the variables in the Udon scripting panel, which is why I put it here.

floral dove

yes, you can change the walk/strafe/run speeds from Udon. Unfortunately, I don't know exactly what this corresponds to on Avatars.
