So theres 4 sliders, moving one up or down changes it's respective number on the board. The numbers are each individual planes divided up and parented to empty gameobjects I have names as positions.

#

So each number is set up to a plane on it and they toggle on and off based on where the slider is.

unknown.png
#

I have the code as 1010 as of right now. There is a button that sends a "Check" event to the object that blocks the path.

#

The screenshot above all this is on the barrier

#

as of right now when I put in the code with the sliders and hit the button to check, the barrier doesn't move.

#

Its the big triangle thing, the rest is all other stuff I got to work earlier.

#

All the variables in the graph screenshot are in the different positions so A11 is the 1 in position one A20 is the 0 in position 2 etc.

#

My thought process was that if all four of the numbers are turned on then it should go through the graph just fine, but if one of the numbers were wrong, the bools would all be set to false and the barrier wouldn't open.

#

but now the barrier just doesn't ever open, and I have no idea what to try because I spent hours last night trying to reconfigure and redesign the graph with no difference.

rotund lion
#

Nevermind, It was something with the button that sends the custom event, All working properly now!

If a person who owns an object leaves the instance, it transfers to the instance master. So...which happens first: OnPlayerLeft or OnOwnershipTransferred?

other question: is there a way to send a debug message to all players? right now I have a script with a synced string that fires a debug log when it's changed, but I was wondering if there's a built in one.

muted spoke
#

Btw it already complains even though it is just in the project and not even in the scene

dawn forge
# muted spoke you mean the editor log right?

Yes, and it looks like you're missing UdonSharp, have you installed that? Your QvPen should have a readme to ask for a specific version of UdonSharp.

Select the tag version that it needs or the latest and download the unity asset. https://github.com/MerlinVR/UdonSharp/tags

Google Translate is astonishingly good at translating Japanese

dawn forge
# unreal grail other question: is there a way to send a debug message to all players? right now...

If you're wanting to send a Debug message to all players, you'll need to Deserialize the debug string on the script, and then fire off debug log event taking in the deserialized variable.

Edit: I am still a newbie too, correct me if I am wrong anybody.

Edit2: I try to keep the networking minimal as possible, so when I don't need debugging, make the objects inactive and or setup a bool checkbox to prevent serialization/deserialization.

#

And yeah I am fairly new to Udon in general, especially Unity. I am transitioning from writing business apps in C# to Unity game development!

unreal grail
#

Yeah, the plan is to use the networked debug string while testing, and remove it later

unreal grail
#

(Sorry for all the questions.) Does SendCustomNetworkEvent also call the event locally? Or does it need to be called separately for the sender?

grand temple

yes it does

Astonishingly good for the fact that Japanese is completely different than english. Like completely absolutely different.

acoustic delta

Yes. It is fine if you are just using Google Translate to understand a document, but please be careful if you are writing a Japanese text in a world, or sending something to someone else in Japanese

fiery yoke

Yeah nah was just talking about getting a general feel for what some instructions are trying to tell you.

I just started messing around with udon and im trying to get both a low quality and high quality mirror working

but is there a way that when either 1 of the button are pressed the other deactivates?

Anyone have success getting deterministic physics to work for multiple networked clients? I'm trying to set up a system where when the owner of an object drops it, a snapshot of its physics state (position, velocity, rotation, angular velocity) gets sent so that other users see the same thing (albeit with a delay). So far with two clients on my own computer I've gotten very good agreement most of the time, but when I tested it with someone else we saw completely different things. I'm on current patch but don't mind switching to the networking beta if it addresses this

grand temple
#

unity physics is not deterministic. In order to do that, you'd have to make your own physics system. That's exactly what the pool table does

slate mesa
#

Ah I see. Thanks for the insight! I guess now I have to decide if that's worth it vrcThinking

native fern
#

What is the intended use of this function? I can't wrap my head around it. To me it looks like it just subtracts one value from the other...

unknown.png
hushed gazelle
#

@austere brook You could do it with an animator and toggle between the mirror-enabled animations by setting a shared int value.

#

Also out of curiosity is there a native node/method for "Is this value contained in "ARRAY OBJECT" that doesn't involve a for loop?

you can probs reverse engineer it into sdk3 if it is sdk2. since its a pretty good base menu for pp

No no I tried in game and it works nicely, because I only interact with VR and not in desktop, so I'm going to have to do the interaction for desktop, that's the only negative point of this prefab

Yep

why would they do that lol

tired crag
#

No idea xD

dapper lion
#

that should be easy tho. its probs just needing some kind of “interact()” private where the actual event is

tired crag
#

Yes

dapper lion

or is there an event on the scripts you can already just call for?

tired crag

No idea, I just know that there are 2 buttons that work in desktop, I'll just re-learn them and change their empty

So the issue for me was that there was some unknown bug that was preventing me from updating the world through VrChat. I tried fixing it but made things worse. I am now going to a backup that still works and I don't have a lot of changes to make so that's good. So a lesson for anyone reading this, make frequent backups and replace them as you progress. It's the only true way to know you're not going to get screwed by some mystery issue

dusty ridge
#

Oh I see

little stream
#

Are there any plans to integrate udon with unity's new visual scripting system?

dawn forge
#

Question: Since Udon is technically a VM running within Unity and is the housekeeper, does it provide and statistics of how it is doing in CPU/RAM/Number of running threads? Like a top command/Task manager? And any limitations of how much scripting can run at an instance?

ivory shoal
#

how in the hell do i debug this

unknown.png
fiery yoke
#

How the hell did you even manage to get that

#

That seems to be an internal error. Which means that you provided Udon with something it couldnt handle. No idea what you did tho.

ivory shoal
#

no clue

#

is there a max length limit on strings? i am syncing a very long base64 string

fiery yoke
#

Ahh

#

yeah

#

Now I remember that error

#

Essentially the network serializer just gives up if you try to sync a string thats too long

#

"what is too long?" you ask? Well its complicated

ivory shoal
#

i need to synchronize the positions of 70 balls

unknown.png
fiery yoke
#

Well good luck with that then.

#

There is a bandwidth limit

ivory shoal
#

how low is it?

fiery yoke
#

¯_(ツ)_/¯

#

https://docs.vrchat.com/docs/udon-networking#data-and-specs

VRChat
Networking

There are four ways you can synchronize data and events in your world: 1. Continuous Variable Use this when you have a variable that you want to update frequently, and it's ok if it sometimes doesn't update to save bandwidth for other things. This will sync for late joiners. Example: A tree that g...

ivory shoal
#

oh my god

#

A single synced string can have roughly 126 characters.

fiery yoke
#

They say roughly. No idea how roughly

dapper lion
#

try delaying the position sync a little bit. like an update process

ivory shoal
#

126 characters

fiery yoke
#

You can send it in packets. But that gets hella complicated.

ivory shoal
#

why is udon built like we're living in 1996 and the dialup internet is a brand new thing

dapper lion
#

omg that image just loaded in lol

dawn forge
#

Ouch... might just split it up into a few, then concat after deserialization?

fiery yoke
dapper lion
#

cus latency

ivory shoal
#

but meanwhile something like roblox has no trouble syncing the position of thousands upon thousands of bricks being physics simulated by a remote player/server

#

or neos which just does it more directly

fiery yoke
#

Roblox gets a share of robux sells and neos doesnt have nearly as big of a userbase (yet).

dapper lion
#

I don’t know if this is a good idea for 70 balls but you could calculate everything locally. and then sync everything via an event with the owner but im not sure with 70 balls lol

#

roblox also uses different techniques to get stuff between players

#

ig itd be like how jars worlds kind of handle things locally until the game/match finishes

#

local-ish

fiery yoke
#

That is exactly what the 8 ball tables do

#

It runs on a self-made deterministic physics engine

ivory shoal
#

ok if i split it into 4 strings it should hopefully be under 100 characters each

fiery yoke
#

It only syncs which ball has been hit were and the rest is calculated locally.

#

Now that I write that out loud. Why are you even trying to sync the balls?

#

They shouldnt need to be synced individually

ivory shoal
#

it synchronizes the positions of balls as well

fiery yoke
#

Hmm thats odd

#

it doesnt need to

ivory shoal
#

it's not fully deterministic

fiery yoke
#

Ohhh late joiners

ivory shoal
#

different framerates, hardware

fiery yoke
#

Well yeah thats true.

#

But you gotta cut corners somewhere

dapper lion
#

frame rate def makes the balls react weird

fiery yoke
#

You can use delta time to rule that out

dapper lion
#

cut corners and then put the corners back on later

ivory shoal
#

well if you just use delta time and move the ball in its velocity direction 2x more on 30fps than 60fps, then it'll be 2x more inside of the ball in a collision and there's your non-determinism once again

fiery yoke
#

A good non-deterministic physics engine can account for those things.

#

But again. You need to have them synced for late joiners.

ivory shoal
#

i just find it pretty ridiculous that roblox in 2007 had better bandwidth limits than a VR platform in 2021

fiery yoke
#

I mean I dont know the full picture. Maybe there is other motives/reasons.

dawn forge
#

Well you're looking at Roblox which was written in C++, and introduces a Lua interpreter. C++ is more closer to the machine and has less abstractions than Unity, since they baked their own game engine to focus on Roblox. Unity and it's C# scripting also has to go through some hoops, and is beefy to accommodate different kinds of games people will make. Also the choice that Photon networking is being used by VRC, kind of introduces its own limitations and or VRC imposed these limitations to help not overload their servers.

#

I still wonder though how Empyrion was able to achieve a massive physics and change in networking, since they use Unity as well, so I am kind of pointing the finger at Photon/VRC.

ivory shoal
#

im pretty sure Unity supports the ability to write C++ modules and use them as dynamically linked libraries

#

Roblox was also based on an engine called Ogre3D at the time

dawn forge
#

Yeah it has IL2CPP and can do that and is much faster than going through Mono. I didn't know about Ogre3D. Now I am curious, gonna read up on it.

I'd do a pre-check in your script before diving in. Here is what I do, this method is called on Start()

stark adder
#

I think I even know which script but.. Which Array ? I am pretty sure I am instantiating all arrays

dawn forge
#

Ermm... no stacktrace so can't help. If you run it in Unity Editor with Cyanemu, it'll spit out the stack and the culprit array.

stark adder
#

I'll try it..

dawn forge
#

But you can do something like I did above, check all arrays after getting them instantiated, so the game doesn't have a fit later, and you can address them right away.

#

That's if you're pulling component/gameObject and or game data that will automatically be defined, not by you of course.

Its not doing it CyanEmu

I've run into a bit of a snag with a script I am using that boosts audio. When you bring any object into the voice region, such as a control panel, the scripts for those objects no longer function...could this be prevented with layers, or is there another way to prevent this behaviour?

#

I'm assuming how it works is that you are already 'colliding' with the voice region box, so it won't let the avatar collide with a second object, such as a button.

fallen chasm
#

I've had this issue in the past when I was attempting to create a volume that triggers something to turn off when the player left it. Basically, every trigger/interact inside the trigger volume didn't work, as you describe. My solution was to compare positions instead.. lemme grab a screenshot for ya...

tribal meadow
#

yes basically

fallen chasm
#

might need to be slightly revised for your setup

tribal meadow
#

so in your case, you made it so the position of the avatar would do the operation rather than a button?

fallen chasm
#

yea, if a player's distance is 'less than or equal to' the position of a target object, you can set another target object to active

tribal meadow
#

ah ok

#

I could play with that and see if it might work

fallen chasm
#

I'm pretty sure I reworked this to toggle based on proximity rather than just disable, so the middle variable called "DisableTarget" should just be "ToggleTarget" or something

tribal meadow
#

ah ok...I see

fallen chasm
#

on an unrelated note... I too have a noodly question for anyone who might be able to help me out.

#

This plays a sound when a player teleports... pretty straightforward, but it seems to repeat the sound for everyone on each person's teleport

#

I've set the sound output to 3d, attached it to the player head and made it fairly small, but I still hear other peoples teleport sound

#

So I guess I'm wondering if there's another way to output the sound that only affects the player who triggered it...

mossy anvil

can you pass parameters in send custom event

somehow

#

slate mesa
#

@mossy anvil passing parameters in custom events isn't supported atm, and there's no way to get variables in a different udon behavior

hoary echo
#

You can totally get/set variables from one udon script to another, using udonbehevahior.get/set variable (That may not be exact, not at my PC at the moment)

void ridge
fiery yoke
#

Yes

#

thats what UdonSharp does

void ridge
#

Or does it do something silly like queue up both those actions to happen on the next frame in some arbitrary order

hoary echo
#

It happens in the order you set it

#

I have a script that does that exact thing, sets a variable, then calls a network event

fiery yoke
#

Thats different

#

Network events do not work like that

void ridge
#

Yeah, I'm essentially worried that it works the same way as syncing variables and sending network events, which are in no way guaranteed to happen in any order

#

(yet)

fiery yoke
#

As long as its local it happens on the main thread synchronously

hoary echo
#

I have a simple script that when you pick up object A, it sets a variable on object B, then calls a network event on object B that references the newly set variable. Seems to work reliable, I haven't had it not pick up the new variable once, yet, in my testing

void ridge
hoary echo
#

Not a sync'd variable, but setting the variable is done via network event. So basically Action on A --> Send networked event to all --> Set Variable on object B --> Call networked event on object B... I think, I don't have it in front of me, haha, I'll verify once I'm done work in a couple hours

We'll have support for this with our upcoming Physics Bones system - but that's outside the scope of this channel, which is specifically for Udon, our system for building interactive worlds.

Hey there, I'm trying to have a trigger in a room, so I made a cube, disabled the mesh renderer added box collider and checked IsTrigger.
The trigger works like expected, however I have buttons and a video player in that room, and to interact with the buttons in VR mode, you gotta put your hands into the button. That's not the case when I disable the trigger object.
You also can't interact with the video player while inside the trigger.
Is there any way to fix this behaviour, or maybe even a better way than a trigger covering the whole room?

grand temple

yep, if you set the trigger to the mirrorreflection layer it won't interfere with other interacts

oh right, layers are a thing.
I'll test that right now, thank you :)

Is there any way for layers to have a rigidbody collide with the environment, but not players?

Well, set objects to environment, and then make a layer that only touches environment?

grand temple

yes, you can make a custom layer and if it is not set to collide with playerlocal, it won't affect the player

chilly crater
#

Sweet, now I can use my cheese idea and not have it interfere with players.

#

Have a rigidbody parented to the AI with a game object parented to said rigid body at a distance away. The trigger has a lookconstraint to watch the cube. Now when the AI goes up/down ramps, the rigidbody goes up/down and makes the triggers tilt up/down accordingly.

Thats an UdonSharp feature which has been made obsolete by now. If you dont have UdonSharp installed you need to get it first.

Thank you for your reply. I have installed the latest version of UdonSharp. In this case, can I ignore the Force Compile Script press?

Looks like ones a boolean and the other is not

eager olive

Hmmm, might just be a visual glitch? One has the checkbox to let you change the value, the other one seems to require a node to set the value. If both actually accept a boolean they should at least behave the same, right?

void ridge

It's a visual glitch, from my experience

#

well, not exactly visual, but, it's limited to the graph. the resulting assembly should be the same

#

just use a Const bool and forget about it

I'm probably going to explain this wrong. But I have trigger colliders for my NavMeshAgent. The world has ramps. And the triggers don't really like the ramps and stay level. I have a rigidbody parented to the Agent that "detects" the floor with a parented cube (the white one) in front of it. The trigger parentObject has a look at Constraint to change the angle of the triggers.

unknown.png
#

Is there an easier way to do this? Because my way isn't 100% foolproof either. The rigidbody sometimes falls through the wall/floor if it pressed into it too far.

#

Or it can rarely fall off a platform.

Why do you need a rigidbody on a collision box that just acts as a trigger?

The navmesh agent goes up and down ramps, and the triggers don't rotate at all.

#

so it can't "see" while on ramps

hushed gazelle

If all it has to do is detect the floor, why is it not a plane or a sphere?

Hell, just put it at the root of your NPC at ground-level because if that's not touching ground then it's airborne anyway?

Hi all, hoping someone can help. I'm almost close to the end of a world project and I suddenly started last night getting:
[UdonBehaviour] Could not load the program; the UdonBehaviour on '<component>' will not run.
on every component that uses a simple shared script for sending networked button events to controller scripts (made either with vanilla Udon or U#). Screenshot below.
Now pretty much every interactive component of my world is broken. :(

I was in the middle of trying to debug another component where for some reason its push buttons (using a different script) wouldn't work in VR mode, only desktop. And now nothing works at all. 🥲

No, but running in Cyan EMU, its failing at the first step when it checks 'serializedProgramAsset', its finding its null and aborting.

The way I know to do this is not specific to Udon - you can add a camera to your scene that targets a RenderTexture, then make a ScreenSpace Canvas with a RawImage that shows that RenderTexture - this will show full-screen on Desktop and output to the Desktop Window in VR (for recording or spectator view). If you're going to do this, I recommend you let the user turn it on themselves, and give them an easy way to turn it off. Once it's been activated in Desktop mode, it's very hard to use your menu or read things in the world.

opal dew
#

@floral dove I'm working on a TV Studio World so that sorta thing would be super handy. :)

grand temple
#

you can make a camera render directly to the screen without any render textures. Render textures will add to the cost and memory usage. All you need to do is set the camera to target eye: none (main display) and not have a render texture set. These type of cameras normally get disabled so people don't make them by accident, but if you make an animation or udonbehaviour or anything that just re-enables the component, it will work

I've got a control panel with buttons that all have the same script on to call another script. But for some reason, a random selection of buttons aren't lighting up. This script is used all over the place on various other buttons and works fine.
For example, Tape 2, 3 and 6 for some reason work, 1, 4, 5 and 7 don't.

And the script for these buttons is just this:

public class ButtonInteract : UdonSharpBehaviour
{

    public bool IsLocalOnly = false;
    [SerializeField]
    public UdonBehaviour ParentObject;
    [SerializeField]

    {
        if (IsLocalOnly)
        {
            ParentObject.SendCustomEvent(EventName);

        else

So I discovered the ease of getting into world creation in vrchat this past week and my mind has been coming up with ideas left and right. I ran into an issue with one of my ideas where the web panel component has been removed and was wondering if there is a alternative being worked on since this feature was removed 3 years ago. My idea was a fandom world for crypto (not for buying or selling just themed). I thought it world be neat to have charts around and unique implementations of graphs, even have different animations trigger when crashes happen. Maybe im asking a bit much but that's just one idea of many that would need the use of something like this.

Hey, is there a way to convert a string to a URL? I have a VRC Url Input Field, and i want to be able to set the url via a udon graph to some string.

fiery yoke
#

There is a reason why URLs arent just strings. VRChat designed the Video Player in a way that requires the user to manually insert a URL OR that the world creator puts in a URL in the editor. You cant do it at runtime.

restive veldt
#

Alright, so instead i will use a Url[] for storing urls instead of a string[]

fiery yoke
#

Yeah you can store urls in a VRCUrl[] array. You just cant create them at runtime.

restive veldt
#

Huh, i wonder why we cant use strings for urls.

fiery yoke
#

Its a security/privacy concern. Video Players communicate with the Web, which is inherently dangerous as clever people come up with clever mechanisms to abuse this which turns it into an attack vector. Minimizing the risk of abuse by limiting the runtime creation of VRCUrls to input fields is a simple but effective strategy.

Is there a way to make players spawn in specific spots upon world entry based on their name

Yes there is a way to do that. But you have to remember that people can always change their name (every 3 months) so theres that

aight ty, what would you say is the best way to go around this then with arrays if im planning on adding and removing in player joins?

grand temple

The max amount of players you'll get will be the soft cap * 2 + 2, so if you set 40 you'll have up to 82. Just make an array with that length and you don't need to resize or recreate it

then I moved the enter to the top of the box collider/stool, and everyone sat above.

now I've moved it to somewhere in the middle, and the small avatar sits fine, medium sits just above, and large sits above also?

is the enter maybe meant to be on the floor, but the collider prevents them from sitting on the floor, and my collider is just configured wrong?

ionic jackal

@floral dove Ok vrcWOAH so I guess triggering animation events using U# public functions not possible right now...
Is there a workaround for this issue?

grand temple
#

yes there is a workaround https://ask.vrchat.com/t/fix-for-animator-apply-root-motion-position-and-rotation/296

VRChat Ask Forum
Fix for Animator Apply Root Motion (position and rotation)

Ever wondered why your Animator breaks and stops updating position and rotation when there is also an UdonBehavior on the same game object? Basically, udon is set up in such a way that instead of applying the position and rotation directly to the game object (ApplyRootMotion), it feeds the values into Udon itself in the Animator’s targetPositio...

#

OnAnimatorMove is meant for the animator to send position data directly to the script and then the script can choose what it wants to do with it. So if you want the default behavior all you do is onanimatormove > get target position > set transform position

ionic jackal
grand temple
#

yeah, the only "bug" really is that the udonbehaviour has to have onanimatormove registered at all times, so the animator sees that and refuses to do anything without being told

fading cipher
#

So I’ve always wondered, what exactly is going on when I’m being sent a networked message in an udon world extra fast? Like in Murder 4 when you die before you see a killer touch you with a blade. Normally I would expect networking to wait until the moment I’m hit or even after, but it seems like there’s some sort of network “force rapid change” that a person can send, am I getting that right?

grand temple
#

That's because networking events have a lower latency than synced position. So on the killer's side, they've already touched you and they send a network event which you receive before you see them touching on your client

Anyone know any groups talking specifically Udon other than here?
My experience so far, lighting, switches and models.

Thanks

theres an udonsharp discord and a vrcudon server as well if thats what youre looking for

Everything and anything please, I'll take whatever I can get, you wouldn't have invites?

You cannot post invite links to other servers here. Gotta google it yourself ¯_(ツ)_/¯

edgy quartz
#

Sir yes sir! no problems

fading cipher
#

So that’s what it’s called, a “Network Event?”

#

I’ll keep that in mind

#

How much overhead does a Network Event have compared to things like the normal positional updates of stuff?

grand temple
#

network events are pretty cheap. You can send 100 all at once without too much issue

fading cipher
#

So why don’t people try using network events to animate things’ positions so you get perfectly timed positional changes instead of using the normal system?

fiery yoke
fading cipher
#

Ohhh okay

stoic mountain
#

Is there some place where I can learn more about the 'ownership' concept ? I realize I need a better grip of what it implies for script execution, collision & such to solve my bugs

fiery yoke
#

However there is significant differences that you only really learn by experience over time

stoic mountain
#

Oh. Well I guess that's a start, but im afraid having inaccurate docs may end up bringing more confusion in the end. :s
Not like I have any better source for now ...

fiery yoke
#

Well yeah. Ownership is relatively basic for the most part. But it gets complicated once you get into the details.

stoic mountain
#

Maybe I should focus on the parts that dont behave as I expected instead of trying to go for the bigger picture.
For instance, Im assuming that udonbehaviours are running on all clients unless the code has condition that prevent it. But im not sure wether the events (interaction, trigger entry ...) are fired for all clients or only the master, if not that would explain some of my problem, but I also have some stuff that do work for non-master players so im a bit confused.

raven peak
# stoic mountain Maybe I should focus on the parts that dont behave as I expected instead of tryi...

Yes it all runs locally unless you have conditions checking if you are the master or owner of something. Interaction and trigger events also fire locally. So only the local player can use interact and if you want to sync the interaction you have that user send a network event. For triggers it does only happen locally but you can have synced objects like pickups or players able to trigger it. So the event is local but the things triggering it can have its position synced.

#

Due to some optimization on vrcs side i would not always rely on triggers syncing with synced objects from a distance or fast movements. So you can check if the object entering is you locally or a object you own and then send a network event to tell everyone something entered.

stoic mountain
#

Ah !

#

Your explanation made me realise something that could explain the behaviors I dont understand.

#

Synced Variable : I used them without really understanding how the sync is triggered, but now I realize it wouldnt make much sense if any client could broadcast the value to be synced at any point. So I assume there's a rule to that, and the rule would be that only the owner would be able to broadcast a change in value ?

raven peak
stoic mountain
#

live I think

raven peak
#

Ok so synced variables will send data about every .2 seconds even if its not changed. The owner of the object is on control of syncing. The owners will fire the preserialization event before sending the data out where you can change the value to whatever you want and it will be what everyone receives. Then the other users will get the deserialization event where they get that value.

#

If you want to mess with synced variables i would suggest checking out the #udon-networking has a option to manually update the synced variable.

stoic mountain

raven peak
#

👍

stoic mountain
#

Ill give the beta a try, hopefully I can send sync updates from non-owners, that would easier to manage

raven peak
#

I usually create a object pool to give everyone ownership if separate objects so they can sync all they want. Another option in the beta is to have a player take ownership then send the sync data they set out to everyone.

stoic mountain
#

well if changing owner ship is simple enough, its already good. Thanks for your help :)

Hopefully this is the right place. Whenever I try to Build & Test my world from unity, it just opens VRChat and goes to my home world. Does anyone know why?

Are you logged in on the same account in both the SDK and in-game?

#

Is there any way to make HTTP requests to fetch data currently? Like if I wanna pull a list of usernames from api I host.

fiery yoke
#

None that are supported by VRChat no.

pallid roost
#

Hmmmm, unfortunate.

#

Is a bit of a pain to reupload every time I want to update an allowed users list. 🤔

fiery yoke
#

There was an "interesting" idea however. Using avatar thumbnails. You basically upload an avatar with a custom image via API, then the thumbnail of that avatar is loaded onto avatar pedestals in worlds, which are accessed by Udon. The texture is then converted in Udon into usable data. The process is quite elaborate, but its a way of automatically updating in-world "stuff" remotely without reuploading the world.

#

That is more "supported" than abusing Video Players at least...

shell swallow
#

I wasn't, now I am, it still just opens VRChat but now in steams game theater. Not sure if that's related.

pallid roost
#

Huh. That is indeed a workaround.
It would just be nice to have a way to provide a config on load to override default things. Like maybe set a different autoplay song or change a userlist or something.

fiery yoke
#

Yeah maybe at some point in the future. But not currently no.

pallid roost

Would there be a reason that my Udon graph would not be properly toggling on and off objects due to packet loss or something? I have a trigger that turns a zone on, triggering another off, and then on another button press reverse the latter. For some reason it doesn't work the first time I push the button, but after the second, it works. Then later after several uses, it stops functioning. Any ideas what this could be from?

fading cipher
#

The only way to set up item spawning and network syncing is to pool the item beforehand, so the world always has those objects and they’re just being grabbed from somewhere way off in the world, used for whatever, then sent back into the pile instead of being destroyed

#

There’s an issue where instantiated objects can’t send their Network IDs to other players so two different players instantiating the same thing would have different IDs for it, and therefore wouldn’t be able to move each other with network messages

#

So for all intensive purposes, instantiating is client side only

You should probably just create a new project and drop your base world assets in there, I'm not sure if there's a clear way to wipe out SDK2 and bring in SDK3

true ore
#

well i might have to rebuild the library then. because it's too large a project to try to perfectly rebuild elsewhere. most of the scenes in it haven't had any vrcsdk2 elements attached to it yet but some have, and for a variety of reasons they need access to the same resources so they're one project.

#

although rebuilding the library never seems to fix stuff. and this will take hours.

#

@fading cipher i see that in the parent folder there's something called VRC.SDKBase.Editor.BuildPipeline, is that something that needs deleting too before one updates to udon?

#

all i did was delete the vrcsdk and example folders, and their meta files

fading cipher
#

Im not quite sure, @floral dove would probably know

floral dove
fading cipher
#

Oh my bad! I always see you in chat so I figured you were available for that

floral dove
#

That said, SDK2 only adds files into the "VRCSDK" and "VRChat Examples" folders, so deleting those two should be enough to remove the actual SDK from your project. However, if you have SDK2 components left in your scenes, that may cause issues as those references won't resolve once you remove SDK2.

#

If I have a synced variable set in the script, can I leave it in for everybody and will get ignored if they aren't the owner?

#

If a script sets a synced variable is what I meant.

grand temple
#

not directly. Synced variables are synced between all players. But it's entirely up to you how that variable gets used. You could totally check if you're the owner rand just use a different variable instead

chilly crater
#

oh okay, I totally read that wrong.

#

I had EVERY synced variable preceded by a If isMaster check.

#

time for a lot of... fixing... Yay.... Sometimes I really hate noodlegraphs

grand temple
#

what do you mean by preceding the variable itself? like doing something with the variable or setting the variable?

chilly crater
#

If a variable was going to be set, I had a check if you were the master before it. and everything was routed around that.

#

Now that I know that ANYONE can set a synced variable, things will be easier.

#

My current project works wonderfully when I'm all alone in the world. with other players? it goes.... yeah... it goes wrong.

#

And navmeshagents only have to have the instance owner set destination, and the object sync will take care of the rest, right?

#

Yeah, that would make sense. I have a randomrange for wanderpoints...

grand temple
#

No no you're misunderstanding again. I mean everyone sees the variable get synced, but only the owner is able to set it

chilly crater
#

OH

grand temple
#

The master is the default owner, bit you can set owner to anybody else

chilly crater
#

if I set the owner of an object, does it also set the children?

grand temple
#

No

chilly crater
#

oof.

#

So if I have a set synced variable in a flow, will non-owners ignore it?

grand temple
#

they won't be able to set it, yes. But if the real owner sets it at the same time then it will be set anyway, yes

chilly crater
#

Okay, now I don't have to rewrite everything. Thanks.

#

I should probably rewrite it anyway... I got a little lazy towards the end. doing get variables from other variables to do stuff. Prefabs.

#

So I should save the ismaster checks for stuff like network events (to save how many are sent out at once), navmeshagent stuff, and randomranges

grand temple
#

I wouldn't recommend relying on ismaster at all. If it's something like setting a synced variable or moving a synced object, just check isowner

chilly crater
#

thanks

grand temple
#

but that's not because it will overwrite what the owner is doing or anything, it's just because if it's an expensive operation there's no point in doing it

chilly crater
#

networking.isowner or playerapi.isowner

grand temple
#

networking.isowner will always check the local player. playerapi.isowner allows you to check if another player is the owner

Hey - apologies if this is a stupid question, but I've been using a bool variable to track the state of an object and noticed that there's no way, when setting its value, to provide a direct value to it via checkbox unlike other Set nodes. (e.g. Animator SetBool) In order to get the behaviour I want, I find myself having to create variables with the value of true and false and then feeding them into the input, which feels like a bit of a roundabout way of doing it. I've attached a picture of what I mean below. Did I miss something or is that how you're meant to actually do it?

Thanks so much for this - apologies, only just got round to trying it. unfortunately it still doesn't like me? I tried the tutorial way - using the fixed_seat controller in the animation slot, but doesn't seem to do anything? After adjusting the seat position, it is still way off. Perfect for some avatars, completely wrong for others. I tried following the readme for the fixed_seat, and using the prefab, but it didn't work either - says "scripts missing" for three scripts, and can't find any to plug in, despite extracting it all in the right place. Also you have to adjust your mesh to the seat_square, which meant dragging the mesh of my chair (sibling of the prefab) into the ground, so the seat lined up with it, then dragging the prefab as a whole back up above ground. There is no highlight, so it can't be selected to test. the prefab collider is above ground and everything, but it defaults to its centre being in the seat (rather than the top of it aligning with the seat). Reshaping the collider hasn't made a difference 😦

Anyone else has this issue? Sorry for the wall of text - super grateful for your help so far ajaja - it's for a uni project. Wish they taught this stuff!

Quick question, OnPlayerConnected is triggered when the host loads into a map as well right? or only on players who connect afterwards?

#

OnPlayerJoined*

dapper lion
#

ummmm. ive never used “OnPlayerConnected” but “OnPlayerJoined” will trigger something if called yes

#

so for a global connect system, youd get the player joined id and send a custom event on all clients thatll trigger an animation to tell people who joined

#

and ofc sync

#

actually... you dont need to sync anything

#

everyone gets client notices by default

north berry
#

i'm using Udonsharp so 'onplayerconnected' shows up as it's part of unitynetworking. onPlayerJoined is the VRC/Udon specific. Equivelant of that. hence the quick mistake there.

h265 should work through the default player on quest, since the android version that quest is running is above 6?

unity alone doesnt work either

also had an issue with VP9/Vorbis, though I would get video, the audio would be scrambled to a very loud static noise for like 10 seconds and then fully cut out. Made a canny of that, no replies (this was back in december)

dapper lion
#

last time i checked. that wasnt the case. but the docs are super old so who knows

hushed shore
#

VP8 didnt work either 😂

dapper lion
#

thats sounds like a vlc issue. did you use vlc in anyway?

hushed shore
#

nope

#

Handbrake

dapper lion
#

thats odd

#

ye. def canny time

hushed shore
#

so far the only codec that seems to work is H264, which.. would require me to buy more NVMe SSD's for my server in the datacenter, and i rather not. Rather have over 2k video files taking 30GB of space instead of 60GB

#

not to mention the bandwidth

#

and as mentioned before, I've listed VP9/Vorbis months ago in canny, but no response whatsoever

#

VP8* my bad

dapper lion
#

compress the videos more if possible?

hushed shore
#

I can try, but 0.6mbit.. a calculator could almost handle that one

#

same issue with 0.2mbit with performance preset for encoder and 80kbit audio

#

i really doubt its a quality issue

dapper lion
#

ok. but does h265 work in unity editor by itself?

hushed shore
#

nope

#

yet it should be supported

#

It just simply doesnt do it in any shape or form

dapper lion
#

that may be a avpro or unity itself issue

#

does default unity video component not work as well?

hushed shore
#

nope doesnt work either for some reason

Trying out a very simple U# script which I also tried as a Udon graph so that if you press a key it switches the player's display to another camera. Works in editor but not in game?

dapper lion
#

do you put a rendertexture over the users display?

serene moat
honest badger
#

@dapper lion If I point the cameras to a render texture on a surface I can see them switching but I'm looking to switch the player camera view ideally

fickle stirrup
#

@honest badger to override player's camera, make an empty game object with Camera inside, with Depth parameter to -1 (or 2, not remember), disable this gameobject and camera, then in game enable it, desktop will not be able to move this camera (so need to make a script for that) and vr players would be able to rotate the camera via real-head (but can be possible to lock/prevent that, somehow)

honest badger
#

@fickle stirrup Gave that a go but the same thing. Works in editor but not in game. I also tried rendering the camera to a texture and i can see it enable and disable but won't replace the player one. I think that I'll go with plan b for now which is switching out a render texture on an object in the scene.

fickle stirrup
#

@honest badger related to render texture, i think that's about to put a World Canvas in front of the player's camera and display the image. and not remember but maybe need to keep enabled camera object but disable it's root and Camera Component. but it should work if uploaded disabled and enables in game via udon. and have Depth property which overrides player's camera

Hey im trying to setup a object that is pickup able but once it touches the remover it will force the player to drop it and disable the object. Is anyone able to help me with the part that forces the player to drop the item?

#

What you have there should work, when you set an object inactive, it'll just pop out of existence from someone's hand. Or are you looking to have it so it actually leaves the players hands, falls to the ground, then disappears?

waxen breach
#

I was looking to have it fall a bit. The item would be placed in a trash can so the object i would want to fall a bit so the player does not see it disappear.

west mural
#

i don't think you need the network event, since that OnTrigger should be called for everyone if the objects position is synced

#

then just set pickupable on the pickup component to false

#

and call a Delayed Event to disable / teleprot the object into a trashcan

waxen breach
hoary echo
#

Hmm, that is a bit strange. I use this logic in a few of my earlier worlds (putting a key in a door), and it instantly pops the key out of the player's hand. What about if you have the player manually drop the object into the garbage can, and have a trigger volume that disables the object at the bottom of the can?

waxen breach
hoary echo
#

Ahhh

#

Ok, that makes sense, I never tested on desktop

#

I'm out of ideas on this one, then! My gut reaction is that you might have to deal with that as a side effect, unless someone more experienced knows a way around it

waxen breach
#

i was hoping that forcing the player to drop the object would fix it

#

but dont know how to do it in c#

unborn hornet
#

VRC_Pickup.Drop()

rough beacon
#

is there anyway to take this and give a object a limit? if not i do have a work a round!

i want make sure this dont happen

#

You should also note, these objects that you're instantiating aren't synced for other players

rough beacon
#

i like that idea. thank

#

well. i dont want synced to other play as a spam safety. they can crash there own pc...

#

later on i will add synced after i fix the spam

void ridge
#

It's not yet possible to sync instantiated objects (last I knew) but it will be very soon

rough beacon
#

🙂 i am ok with that. to tell you the truth, no one really come to my world for popcorn. they want to watch movie 🙂

dapper lion
#

ok, ngl. a lot of people got mad at my movie theater for not having popcorn. so please make sure you have popcorn lol

dapper lion
#

ok, so i hav a question. will pickups desync if an object child is moved from parent to parent between quest and pc instances?

floral dove
dapper lion
#

the object pick up will be a child of whatever touches/collides with the pickup

novel tulip
#

With the SDK 3 worlds, is there a way to playtest them without restarting the client (like an avatar, just reload) or do I need to close and open the client every build?

raven peak
floral dove
dapper lion
#

yes

floral dove
#

Ok - then you'll need to sync the new parent object instead, and use a Custom Event or a Synced Variable to actually change the parent of the Pickup for each player in the instance.

novel tulip
floral dove
#

If you want the effect of having the pickup follow a new Transform instead of the user's movements, you could instead just set its Transform to the position and rotation of the "Parent" object, offset by some amount, each frame.

dapper lion
#

oh, that makes sence

Ok so I'm approved to upload my first world and tried twice so far, started doin a lil research and I'm wondering if its because I'm using the avpro instead of the other prefab screen. I heard when I started doing this adventure that avpro requires a license but after testing it and finding it was working I thought i might have misunderstood. But now I saw something about avpro will work in editor mode without a license. Would this be the reason I'm not able to upload and/or will I be wasting my time uploading just to find out my screens don't work?

lusty fjord
#

how do u pick up a player if u dont have a vr headset. i only have a windows 10 pc.

dapper lion
#

@lusty fjord make platform with a stick pickup as the parents. then make a localposition set up that transforms the player to stay on that platform. then pick up stick and move players around

whaaa

#

I need to add a newline to UIText and "\n" definitely doesnt work. I've also tried using the Convert.toChar node and setting 10 and 13 (\n\r) and concat with existing text. I'm at a loss

grand temple
#

\n is an udonsharp thing. If you're using graphs, you literally just hit enter. It won't display the lines but they'll be there, and you can scroll up and down with arrow keys

novel tulip
#

weird. Basically I want to print live info to a UI text object, so concat a "string" node with just enter in it would work?

grand temple
#

not the word "enter" to be clear, but by actually pressing enter that will make a newline

novel tulip
#

Right lol

grand temple
#

the text boxes in graphs only display one line at a time, but they support multiline input

novel tulip
#

good lord.

#

I guess i should just use udon# tbh

#

I come from C#, .net and java so graph editors are not my favorite

grand temple
#

I think the real solution would be to whitelist stringbuilder

novel tulip
#

That would be so nice honestly. I wanted to try to force myself to use the graph editor to lean udon but i am so frustrated right now I cant explain how many hours of screaming you've just saved me

I'm trying to detect, if the user has opened his menu by calling every now and then Physics.CheckSphere(playerHead.position, 5, MASK_UI_LAYER). At the moment I test in LateUpdate with a counter every few frames, because it is not necessary to respond immediatly. Is there a better way to test e.g. every second if the user has opened the menu? I was thinking about SendCustomEventDelayedSeconds and then inside the called function enqueuing iteself again, but I feel weird creating "recursiveness" like this. Or is there maybe a whole different way to detect the user opening their menu?

how do I make the video player flipped when looking in a mirror?

#

Can anybody gimme a small idea of what is (OnPickupUseDown) and (OnPickupUseUp) Event.

unknown.png
grand temple
#

when you have a pickup component on your object, this allows players to grab the object. When they click their trigger while holding the object, udon will receive OnPickupUseDown. When they release the trigger, udon will receive OnPickupUseUp

errant ivy
dapper lion
#

does "allow transfer ownership" cause unusual client behaviour when testing 2 clients locally?

grand temple
#

It's pretty buggy on live at the moment and will cause too many extra ownership transfers that may result in clients disconnecting, yes

#

It received a bit of an overhaul in the latest Udon networking update beta, it should behave much better

dapper lion
#

currently testing on live! also my first time acc using the test feature so im just curious why 1 client would "unusual" itself and the other is fine but i think i found the issue that may be causing the "unusualness"

grand temple
#

for now, just disable ownership transfer on collision. It is not recommended

dapper lion
#

all ownership was disabled. but i think it was a synced position spam (messing with physics currently

dapper lion
#

what normally stops a pick up from being manipulated in desktop mode?

fading cipher
#

Anybody here ever written their own grab system instead of using VRCPickup?

grand temple
#

varneon did for his cars

#

it's a lot easier now with input events

floral dove
grand temple
#

I'm not entirely convinced that there's much of an advantage to making your own though

dapper lion
#

i acc just attempted to remake the grab system just now because i cant manipulate the object lol

#

did the little rotation floats and keybinds but it does not budge in hand

#

do children solidify manipulation?

#

they do! why

fading cipher
#

I'm having grabbing issues with multiple different objects that I think would be resolved with my own system

#

Plus I can make it communicate with a custom object pooling/networking system

grand temple
#

You're gonna have trouble with sync if you don't use pickups. They'll float behind the players

dapper lion
#

nvm, what causes manipulation to void?

twin drift
#

I have a large collider to detect when a user is in a room, however when it's enabled none of my interactable objects are interactable in VR (although they are in desktop) Is there anyway around this?

grand temple
wanton oxide
#

you can use trackingdata

fading cipher
#

^ bocud already helped me out with this for having player indicators

dapper lion
#

could work

grand temple
#

sure, that's actually what I'm doing in hook junkers. It's a lot more complicated though

fading cipher
twin drift
dapper lion
#

so... are there any known reasons why desktop manipulation would not be present?

fading cipher
#

@dapper lion I haven’t had the ability to grab any of my VRC pick ups with desktop in that month or so that I’ve been tinkering around

#

That’s part of the reason I want to remake the system, instead of debugging something broken I might as well make my own

dapper lion
#

i kind of made my own but it doesnt flow right. but this is literally for a stick rotating, thats all i care about lol

fading cipher
#

Yeah I need a full on sword-grabbing system

#

Not to mention I will eventually have custom swing animations for desktop users, which again I know I could do with "using" vrcpickups but I feel like syncing a single "grabbed or not" value and using tracking data would be way more efficient instead of syncing its position like usual

dapper lion
#

ok nvm, i think the latest client might have a pick up bug

#

yea, i just went to 3 other worlds where i knew you can manipulate objects. is that a desktop setting?

fading cipher
#

Quick note, I've mentioned this before but never got a response... I think VRC's Input Events are bugged for Vive players but I need to do a bit more testing on my end

#

I have yet to have a single vive user successfully open my menu, which requires a grip and a swipe, but I need to throw in some debugs and specifically get a Vive user to test with me

#

Unless the issue is that Vive users can't "grip" without also "use"ing? because that's the whole thing, you have to grip without squeezing use (for most people you'd be pointing your finger doing this)
