[quartz meadow]

I dont see any technical reason why they dont support string arrays or something, but here we are lol

thats a unity issue tho

[indigo wagon]

List to array function can be coded tho

I've made one in bace c# before and it should be similar

[quartz meadow]

I would actually need the other way around, an array to list (even temp) for the uiity dropdown thing to work

its just a matter of udonsharp not supporting lists

cause udon itself doesnt support lists (yet, they said they are working on it)

[indigo wagon]

Excuse me what

[quartz meadow]

but hey, the udonsharp guy just got hired onto the team, so fingers crossed

[quartz meadow]

yes, you heard me

[quaint kernel]

Hello! Udon keeps crashing and burning on me when i attempt to add a simple button, i've tried deleting and reimporting but to avail. i get this error. (i'm using a freshly downloaded sdk from today and 2019.4.31.f1)

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

and the udon graph program asset is broken like thus

[night viper]

you have to add it to a game object first. Also "not set to an instance of an object" means a program has empty (none) variables like on this pic. If they are public you need to put an instance there (on my pic i need an AudioSource instance)

[quaint kernel]

okay, sure but this is what i get then

[night viper]

what does the code looks like? When you open it

[quaint kernel]

when i took that picture, i had nothing in there

yeah i can't change the gameobject, something's broken for me

okay so, solution: just drag'n'drop thing into the gameobject bit

then it works

[night viper]

yes, that is how public variables work. You cant leave them empty (none) or you will have the error of "not set to an instance of an object" (you can only drag objects there when the script is on an object, not from the folder)

[quaint kernel]

yeah but there should be the option of adding the thing to the box (the little circle) but that wasn't present here. drag'n'drop worked tho

[valid totem]

I have this group of rigidbodies that I want to constrain their position to another object on an event, or at least give the appearance of it.

I've tried using spring joints, configurable joints, rb.moveposition, transform.position, position constraints, clipping with a collider, and I'm sure some other not-best-practice thing to do to try and make it work

Does anyone have suggestions for how to move a rigidbody with another object as if it were attached with a position constraint or fixed joint?

with AddComponent not exposed I can't create/destroy joints via udon

[agile reef]

Does anyone know how to make a food item thats edible with udon sharp?

[grizzled trout]

hi. how do you detect when two spesific objects collide? like say key a with lock a.

[wind atlas]

I assume the key is a VRC Prefab Pickup. Give the lock a trigger collider, then in the script use the OnTriggerEnter event to detect the key. That's pretty much it.

[wind atlas]

Honestly, you would do that almost identical to the key/lock problem. You would just have a trigger collider that's on the players head.

[grizzled trout]

actualy i was trying to make it all from scratch

[wind atlas]

I meant to say VRC Pickup. What do you mean from scratch?

[grizzled trout]

Oooh

i thought you ment prefab like the things you can download

[wind atlas]

Nah, just brain pooped.

[grizzled trout]

understandable

we all have our moments

well you see, i have it set so the key sticks to the hand when you get close to it , that way you dont have to hold grip the whole time

[agile reef]

Well I was more so referring to creating an item that is triggered to reset its position and play a sound when the player lets it go

[grizzled trout]

i might be wrong but i think this is the kind of node structur you would need . the "spawn" is an empty that you would add to it and set where you want your food to reset . you will need to add an audio sorce to your world with said sound

basikly the "on grip" is going"when let go" with the false

[agile reef]

oh alright thank you

[grizzled trout]

np good luck.

[waxen kiln]

someone explain to me why udon gives an error trying to get something as simple as wether or not an object is enabled or disabled?

all this is supposed to do is check if a game object is enabled or disabled, then save that value for later use

[wind atlas]

Looks like CourseBool1 is a GameObject and not a bool.

[waxen kiln]

if CourseBool1 was a GameObject, the line connecting it to activeSelf would be blue

but it is definitely a bool

there is also nothing special about the GameObject assigned to Course1

all the parent objects are the same

so yeah, its not anything to do with the GameObject itself

[grizzled trout]

i mostlikely am wrong but anrt bool are more like is it true or false and anything with a value asking for an actual number?

[waxen kiln]

yeah thats not it

i'm trying to get a bool, then save it as a bool

its not being converted to an int (number) at any point

[grizzled trout]

ooh

just figerd the "value" part was asking for a number but yeah i am not vary knoalgable

[wind atlas]

You are hovering over sendChange, of course it shows you it's a bool. Look at the variable window, what does it say?

[waxen kiln]

i'm actually hovering over value, not sendChange

[wind atlas]

What type is Course1? Maybe you could try posting the whole graph.

[mighty fjord]

Could the graph might be having issues compiling, does it say OK in the top right when you try to compile it?

[waxen kiln]

yeah it say ok

[wind atlas]

Yeah, my other guess is that another part of the code is causing the issue. Otherwise it's some sort of bug.

[waxen kiln]

i know for a fact its not something else giving the error, because this debug will run first, then the error happens

so i've narrowed it down to just this part

but whats weird is that, this same code in CyanTrigger instead of Udon Graph gives the intended results

i tested it in CyanTrigger instead and it works, so is this just a bug with Udon Graph?

[grand temple]

have you specified a gameobject in the inspector for Course1?

[waxen kiln]

yep

[grand temple]

may I see it?

[waxen kiln]

the sensoring is just because i'd prefer to not show the name of the object, it kinda reveals a lot about my project

and heres an image from up in this channel a bit, the game object itself

is just a transform

[grand temple]

if you click on the error it should give more information

[waxen kiln]

thats also up in the channel a bit, here it is again

[grand temple]

Are you using SetProgramVariable anywhere?

[waxen kiln]

nope

[grand temple]

Seems like you're storing a bool in the Course1 variable somehow. Can only do that if you're really manhandling something

do you set Course1 anywere?

[waxen kiln]

the only other time Course1 is ever used is way after this error

this is to run later, to change the object back to the state it was saved in

but since it runs later, actually on a different event entirely, this wouldn't be the problem

[grand temple]

somehow a bool is getting into your gameobject and I've never heard of that being a bug before 🤔

[wind atlas]

Very weird.

[waxen kiln]

thats also what i thought the error message said, but still makes no sense

[wind atlas]

Try making a new scene and rebuild step by step, if the project isn't too big.

[waxen kiln]

i really can't afford to do that

if the issue really is a gameobject having a bool stored in it, thats impossible

at no other point, ever, is Course1 referenced, not in this entire Udon Behavior referenced or called upon from another behavior

[grand temple]

try renaming the variable

[waxen kiln]

...

i renamed it to Course0, assigned the gameobject back to it, and now it works?

[grand temple]

either the inspector is serializing wrong or you've got some other program doing SetProgramVariable

[waxen kiln]

i'm testing it one more time

well whatever it was, it works now, so i'm just not gonna touch it again

[sand basalt]

When user interacts with slider using vive sticks, touch pads keep changing value even when not pointing at the slider. Any suggestions? Can i turn touchpad control entirely off?

[dreamy gorge]

can someone show me a tutorial on how to make objects synced and pickup-able?

[sand basalt]

just add VRC pickup, VRC Object sync, and Box collider components on model.

[dreamy gorge]

by chance do you know what makes a pickup object super laggy when holding it? it teleports around and only smooths out when you hold it and start walking

[sand basalt]

should be fine locally, remotely it will always be laggy

[grizzled trout]

hi, i am trying to make a "clapping" thing where say if a player puts there hands together it makes a clap sound , i got a graph to track where the players hands are but not sure how to get when the hand boxes are touching.

[sand basalt]

Vector3 distance node, measures distance between 2 objects in float, then use lessthenorequal to check for bool

[unborn hornet]

We are able to have a None sync script on the same object as a Manual or Continuous without issue, right?

[sand basalt]

Well manual or nonr doesnt work with object sync script on the same object, so can be a problem.

Anon, can you help me with slider problem?

[sand basalt]

this

[grizzled trout]

somthing like this you mean?

[sand basalt]

Yeah, its in meters though

[grizzled trout]

Ooh thanks for the heads up, !

[unborn hornet]

Not worried about objectsync. Just straight custom scripts only.

[grizzled trout]

Thank you! got it working, hope you get the help you need, wish i knew bit more about stuff to return the favor

[sand basalt]

❤️

[wind atlas]

You have to turn off navigation to stop that I think.

Not sure if you can do it in the event system and it gets carried over into vrc.

[wind atlas]

Otherwise you have to turn off these individually:

[sand basalt]

Thank you so much

❤️

[grizzled trout]

hi again, anyone know how to set a sort of timmer? like i want to set it up so if a player stands on a board for to long it moves out from under them

[paper plinth]

When the player enters the trigger zone capture datetime.now in a variable. Then gate the payload with datetime.now geq your variable

[grizzled trout]

thanks, i think i understand, i will try that

[paper plinth]

Ask again in about 8 hours if you don't get it and I'll do the nodes and screenshot it for you. That's also not the only way to do it. Also don't forget to use time.addseconds (or is it datetime.addseconds) to get your "timer done" value. Then when the current time meets or exceeds your timer done value, execute the true branch.

[grizzled trout]

alright, thanks ^w^

[vague mantle]

does anyone know to set up buttons that you can physically push to toggle? or where to get them?

[tough finch]

on https://vrcprefabs.com/browse > SDK3 prefabs > physical interaction

[grizzled trout]

sorry to bother you but i been trying my best and still cant figure it out

[paper plinth]

hey

hang on lett me load up unity

[grizzled trout]

ooh thanks!

[paper plinth]

That's one way

and with fCoutnerSpeed at 1, a timer value of 5 is like 5 seconds

here's another way

coincidentally that is also a 5 second times

[grizzled trout]

wow, thanks .that looks a bit more complex then i thought lmao,i will give it a go

[grizzled trout]

just making sure , you mean setting the FTimeRemaining in the first screnshot value to 5 right?

[paper plinth]

yup

and then decrease it every frame until it reaches 0 and then execute your code

[grizzled trout]

thanks, i will work on it.

[paper plinth]

wait

there's prefabs here somewhere for timers

huh can't find them

maybe they're on the prefabs spreadsheet

https://docs.google.com/spreadsheets/d/e/2PACX-1vTP-eIkYLZh7pDhpO-untxy1zbuoiqdzVP2z5-vg_9ijBW7k8ZC9VP6cVL-ct5yKrySPBPJ6V2ymlWS/pubhtml#
@grizzled trout if you're more comfortable with prefabs you might try the timer queue prefam from cyanlaser here

[grizzled trout]

might do that, i was hopeing to try and do it myself hehe but if i cant figure it out i will do what i got to do. thanks for the help

[grizzled trout]

ooh i figured out what i did wrong, i forgot to set it to change time remaning . its working now lmao.

[paper plinth]

eyy good job

[paper plinth]

isn't this how you get an array element? This keeps crashign the program

I loaded an array of transforms Waypoint[] with items from the inspector...

[wind atlas]

How many elements are in the Waypoint array? Aside from that, seeing the error would be useful.

[paper plinth]

there are 19 elements

Object reference not set is the error

I see some other objects here that aren't set up the same way and I think those are the ones crashign the program

[wind atlas]

The error should show you which instruction is causing it.

[paper plinth]

yup that was it

what confused me was that I had 10 of the same gameobject and modified one of them and was testing off that

but I didn't realize it had broken the other 9 gameobjects

I like object pools and trytospawn
this is good stuff
good show devs

[fading cipher]

Ay yo momo if you're lookin here

are we gonna get leaf bone support anytime soon

😢

[fiery yoke]

For what? Humanoids?

[fading cipher]

Yeah!

Being able to attach things to finger leaf bones that are meant to follow fingertips would be nice 👀

[fiery yoke]

Unity does not even support that lul

For some reason they thought leaf bones on armatures are unessecary

[fading cipher]

well

color me deeply saddened

[fiery yoke]

Indeed. For normal games it's usually not that important, but for VR it's incredibly important. So maybe at some point...

[mighty fjord]

Would be nice if we could atleast have Udon be able to retrieve the position and rotation of the first child of the distal bones

[fallen chasm]

I'm trying to set up an axe that sticks to trees (triggers), but falls with gravity otherwise...

this works in unity

but in game, it's stuck in kinematic

any advice is much appreciated

now that I'm thinking about it... this is probably more of a physics issue than an udon issue

[grand temple]

if you have objectsync on it, it will control kinematic and gravity so you can't set it through the rigidbody. You need to set kinematic and gravity through the objectsync

[fallen chasm]

oh... that might be over my head then

[grand temple]

it's nothing complicated, just use objectsync set kinematic instead of rigidbody

[fallen chasm]

!

didn't know I could just grab it like that

lemme test it out

nice

doin' a quick build and test to verify but... does this method not work in unity?

scratch that... still floating :/

aha!

[grand temple]

can you add a debug log to make sure it's getting to this point?

[fallen chasm]

I can, but I just found the problemo

when I added the new variable, it came in empty on the triggers

I just needed to set it

eeexcellent

it's working in unity -- gonna try in game

awesome

[tawdry gorge]

Anyone able to help commission for a home I’d like to have?

[weary scroll]

So I bought vr chat plus and it keeps expiring like every 20min and idk why

[valid totem]

https://ask.vrchat.com/c/commissions/world-commissions/34

[bold marlin]

Is there anyway to turn off Sync of a object and then it back on later?

Got an object people can pickup and it gets addforce from a collision event to fly off, but the sync screws with the addforce making the object bug out.

[quartz meadow]

use an empty gameobject with a syncing script as a proxy

ive been having an issue where my UI canvas keeps adding a box collider way bigger than the canvas, physically blocking me from reaching the buttons or my cursor from reaching it. Changing it to "istrigger" does allow me to walk through it, but not my cursor. No matter what I set the boundries to in the editor, they always revert when playing. anyone know a way to fix it?

[quartz meadow]

fixed it by setting my game object z scale to 0.0001

[magic drift]

Hey, is there anyway to enable or use old locomotion in Udon?
I prefer how it handled falling/jumping/"climbing" etc

[mighty fjord]

There's a node called 'UseLegacyLocomotion' under VRCPlayerApi which is used to bring back SDK 2's movement system

[hollow widget]

Did you know how to script to return object pool that we spawn one by one to object pool that we don't spawn?

[hushed gazelle]

If I remotely change an udon behaviour value from another script, will that trigger OnValueChange?

Eg; from Script A I tell Script B to set ThisBool to False, will that trigger ThisBool Change on Script B?

[mighty fjord]

That's how I'd expect it to work

[hushed gazelle]

I ask because it's something you have toggle when setting the value in the local script, remember.

[mighty fjord]

Oooh, right, not used to the recent features in the Graph I guess x)

[wind atlas]

Anyone figured out how to use the VRCObjectPool for player management properly?

I noticed that spawning of objects and manual syncing them doesn't work as expected. I think it's because the children only OnDeserialize and OnOwnerTransfer when the object is enabled? I get super inconsistent results in Build and Test mode. Sometimes it works, sometimes it doesn't. It makes it super annoying to work with.

I'm currently just doing my own pool for player management.

[storm ore]

are there text based compilers from traditional languages like c++ to generate udon bytecode?

[grand temple]

there is one for C# called Udonsharp. That is the biggest and most well maintained alternative to graphs

there is another one for python but it hasn't been maintained in a long time

nothing for C++ that I'm aware

[storm ore]

i appreciate the nod to newbies with graphical programming languages. but it can feel cramped compared to the power of text languages

both are welcome for different reasons

[grand temple]

yes, catering to every level is the whole point of allowing custom compilers 😄

[obtuse agate]

There is another C# to Udon compiler https://github.com/Xytabich/Katsudon. Since it’s based on IL, it might be able to compile from other languages as well

[wind atlas]

Yep, did my own pool and stuff actually works now.

[manic yarrow]

@grand temple How would I go about changing a bool on interact, but nothing else?

[grand temple]

interact > set bool

[manic yarrow]

All I can find is Boolean[].Set

[grand temple]

drag your variable onto the graph while holding shift

er ctrl, not shift sorry

[manic yarrow]

I assume I just need a unary negation if I want it to toggle

[grand temple]

yes

well, you'll need to plug the "get" into the unarynegation too

[manic yarrow]

Right

I haven't touched Udon stuff in a while so I've forgotten a bunch of basic stuff

[grand temple]

GetProgramVariable

[wind wedge]

Alrighty everyone, Its me again 😭

Just a simple question this time around, and its for everyone.

What are your favorite / Must-Have Udon features in public worlds?

[unborn hornet]

Depends on the type of world and its intention.

[wind wedge]

just a basic social world

[lavish summit]

I prefer Dasani instead XD

[indigo finch]

The general ones I like to add to a more social world are a volume slider for any music or sounds, a 'seat toggle' to turn off any stations in a world, a world darkness slider for those that like to sleep. Other than that, sometimes I like having a mirror toggle at the menu itself, as well as some toggles for a more efficient experience for those with lower-end pc's (particle toggles, low detailed water, etc). That being said, anything goes; it entirely depends on what's in your world. The best features are usually world specific (rain, game toggles, etc)

[chilly crater]

Are VRCStation animations local or synced? I was thinking of making a local unsynced VRCstation event to call whenever the localplayer dies.

[topaz jetty]

never seen that one before, are there any advantages over udonsharp?

[quartz meadow]

https://github.com/Xytabich/Katsudon/wiki/Difference-from-regular-use-of-C%23

id imagine not right now unless there are some specifics you need, but in the end, no matter what you do, you will be limited by what udon whitelists

[paper shell]

/clear

[hazy shore]

Yo, I didnt know where else to ask this question, But i have uploaded an avatar, It shows up on VRchat.com But not in game. Where do i look.

[eager olive]

Not really #udon-general , #avatar-help might be a better place!
But it should show up your avatars menu, at the very top.

[cunning basin]

disable grabbables

[wind atlas]

Delegates and events? Interfaces? These would make life so much easier. Although interfaces aren't supported for custom types it seems. I guess you would still mainly work with monobehaviors, which isn't that big of an issue.
Looks great though. Wonder if there is any catch to it, aside from it being alpha.

[edgy ingot]

is there any particular reason we don't have List<> yet? if its a technical limitation i'm just curious
U#'s been a powerful asset and i feel like not having List<> is holding us back ❤️

[fiery yoke]

Generics are...weird. And Udon is not designed to handle them. Currently Udon generates a "string" for every "operation" that you can do in the VM. With generics you would currently have to generate all of the possible operations for all of the possible types. (Or something like that).
Thats why Generics are currently not a thing. Udon is not designed to handle those easily.

[edgy ingot]

ah ok

do you know any workarounds for GetCustomParticleData() by chance?
that's literally the only reason im asking about list lmao

[fiery yoke]

What? You cant set the customer particle data in the first place, so why would you want to get it?

[edgy ingot]

set needs a list aswell

[fiery yoke]

Yeah. No workaround. Unless you manage to get a list, which looks exactly like the one you need from another function :P

[edgy ingot]

and its not like i can MAKE my own List<> either, i'd imagine it has to be the EXACT type
(System.Collections.Generic.List)

im trying to convert this for use in udon
https://assetstore.unity.com/packages/vfx/particles/spells/living-particles-105817

i can use the particle "fog" ones since that's just this

welp, i shall wait or think harder, thanks for the quick response :)

[fiery yoke]

Yeah no, custom particle data is not supported in Udon afaik.

[edgy ingot]

also just curious, what's the best way to get player position? i'm doing it based on the hip bone... is there an easier/more optimized method?

[fiery yoke]

VRCPlayerApi.GetPosition :P

[edgy ingot]

;-;

i dont know how i didnt see that

[edgy ingot]

ok now im just confused
my C# is a bit rusty as are my debugging
this issue is in CyanEmu so idk if its just related to that

OG source is this

wait...

[edgy ingot]

update, now it's saying something about a zero-sized array

[fiery yoke]

It said that before as well

And I suspect that youre accidentally creating a zero sized array, which is not allowed.

[edgy ingot]

actually the only error seems to be this now

[fiery yoke]

make sure worldCapacity isnt 0

[edgy ingot]

i specifically changed that in the declaration

[fiery yoke]

Your errors look very weird. I suspect you have some plugin installed. That error does not happen on a correctly installed and used Udon SDK

[edgy ingot]

its ConsolePro from uhhhh lemme look at my assets real quick

https://assetstore.unity.com/packages/tools/utilities/editor-console-pro-11889

this is what vanilla console says

ok there was a removed script on the main prefab, i removed that and that error went away for a little bit

gonna reimport the sdk just in case something got borked

[blissful void]

Hey guys.
Little question. I´m making Worlds with SDK 2 and wanted to shift to SDK 3.
Many people say, do it, its so much easier, etc.
So i did...and i don´t get it. It seems i miss something.
I watched tutorials and what not but all of them are MUCH more complicated then SDK 2.
If you want to open a door in SDK 2 pick a trigger component and put the values in.
In SDK 3 you have to WRITE the code first with Udon# or Notes??
Oh and most Tutorials say the buffering system of Udon is completely broken. You have to work with, Variables?
Do i miss something?
I don´t want to talk Udon down, i really just think i miss something here O.o

[blissful void]

"In SDK2, every operation that worked with bools had the ability to toggle the value. This does not exist in SDK3. The proper way to toggle an object requires 4 actions. See the mirror toggle guide on details for how to toggle an object."

Is this really the case? O.o
If yes, how is this "more user friendly"?

[night viper]

CyanLaser made a tool called CyanTriggers that lets you use Udon as if it was the SDK2 interface. You could try that to make your own scripts with Udon. https://github.com/CyanLaser/CyanTrigger

[fading cipher]

Is there something about Udon that keeps from interacting with a BoxCollider's bounds.size?

[fading cipher]

apparently you're just not supposed to touch BoxColliders' bounds at all doesn't work on a collider if its gameobject is disabled

[craggy ingot]

Hey how do I open a door with a key placed on the lock?
I am using Udon Node Graph with animation
Thank

[vestal mesa]

Hey guys sorry noob here - but would this pack work in VRChat - https://assetstore.unity.com/packages/3d/environments/terrace-pack-38323

[edgy ingot]

yeah why wouldn't it? it's just 3D assets

[cunning mist]

The only thing that will not work is the included script for the Animated Birds, though theoretically that's a quick reproduction inside of Udon. Outside of that, you should be good to go!

[edgy ingot]

^^

i've been trying to re-create something from a pack and it's been a nightmare to get working

[broken bear]

Silly question, but is there any way to compress the serialized udon asset? trying to shave off 100k here or there

[edgy ingot]

other than optimizing the code, no
the amount you'd shave is negligible 99% of the time
there's a thing called PNG Gauntlet, you can mass compress textures, then crunch from there if you want

[scarlet lake]

I gotta log in for the update and forgot my goddamn password 🤦‍♀️

[edgy ingot]

mind if i ask a couple things? having some debugging issues rn lol

[cunning mist]

I'm presently at a gas station on a three hour car ride, so unfortunately you've got me at a bad time

[edgy ingot]

gotcha gotcha no problem

[obtuse agate]

When you build a world, the assetbundle will compress all assets with LZMA. Text assets like serialized udon compress really well, so world size won’t reduce much even if you somehow manage to compress the udon asset

[broken bear]

Ah good to know

[tired fractal]

Is there any person that can help me making an avatar?

[stone kelp]

Try #avatar-help

[edgy ingot]

anyone have any experience with Material.SetVectorArray()?
is it able to dynamically add to the list the material works with or is it something i set BEFORE running?

and yes i'm the same person as last night/earlier i just got the single player version working :P

also ignore the foreach being scuffed i know i was just testing stuff

Where StringBuilder()?
Why no StringBuilder!!!

[magic drift]

Hey, I wanna make it so when I click the mirror it turns off and turns on a more optimized one

How might I go about that?

you can set Vector Array during runtime. However that wont resize the array in your shader. In your shader you need to define the array with it's maximum size.
Probably want a second property to pass the length of the array to your shader too because of that.

[topaz sorrel]

Trying to make it so that when you interact with a button, a random object from a certain object pool will spawn.

This is the simple script I'm using, but I keep getting this error every time I trigger the button to spawn an object

sned hlep

[grand temple]

did you assign the "Deck" object to the inspector?

[topaz sorrel]

Assign it to inspector?

[grand temple]

you need to tell it what object "deck" is

to do that, you need to make deck be a public variable

then it will show up as a slot in the inspector

and you can drop in your object pool to that slot

[topaz sorrel]

Oooh yeah. Yes the code knows what Deck is, I dragged it in from inspector and it's a public variable

ye it's a public variable

Still doesn't work though, not sure why

[grand temple]

and the inspector?

the object you put this script on

[topaz sorrel]

I put this script on a different object, do I have to make sure that's a public variable, too?

[grand temple]

that's not what I mean

I mean, you put this script on an object

that object has an inspector

what does that look like

[topaz sorrel]

OOOOOH okay got it yeah I didn't set the public variable down in the udon script.
Thanks, wouldn't have realised that without your help

[grand temple]

also in order to spawn from an object pool, you need to be the owner of it. If you don't transfer ownership, the only person who will be able to spawn from it will be the person who's been in the instance the longest

so you just need to add a Networking Set owner node. Plug in Networking Local Player and the gameobject of the object pool

[topaz sorrel]

Where do I attach the set owner node?

[grand temple]

after interact, before shuffle

[topaz sorrel]

Like this?

[grand temple]

yes

[topaz sorrel]

Pog, thanks

Do I have to add anything else to the script or should it work fine just like that

[grand temple]

plug in the player and the object

[topaz sorrel]

Plug them in to what?

[grand temple]

the setowner

you need to tell it who should be the owner and what object is changing ownership

[topaz sorrel]

Alright, I set the object but how do I set it so that whoever presses the button is the player who gets ownership

[grand temple]

networking local player

interact only happens for the person who clicked the button so you can just assume local player

[topaz sorrel]

So something like this? DeckOBJ is the object that has the pool assigned to it

[grand temple]

yes, that could work but you don't need to have a separate public variable. You can get the gameobject from the Deck itself

[topaz sorrel]

Oh alright, and how would I do that?

[grand temple]

vrcobjectpool get gameobject

[topaz sorrel]

Like this?

[grand temple]

yep

[topaz sorrel]

Alright. Thanks for your help!

[left fulcrum]

ok so, completely new to world creation, literally the only thing i need to do is toggle an object and multiple tutorials later none of them work, what do you reccomend?

[left fulcrum]

I follow 8 VIDEOS and NONE worked out

[wind atlas]

I recommend patience. Chances are, you don't understand some basic concept enough yet to see what's going wrong. Take your time to get to know them. If you feel like you are stuck, post whatever error you are getting, people will generally help if you make it easy for them.

[left fulcrum]

how do you think i should start

cuz literally all i need to do is a trigger

[stable glen]

From the beginning, really. Do multiple iterations of projects and test to see what works out better.

[wind atlas]

We don't know what you know, or don't know. There are enough tutorials that teach that, knowing some programming fundamentals helps.

First sentence got out weird, what I mean is, tell us what you tried, what doesn't work, etc

[left fulcrum]

im just tryna make a simple object on-off switch for an animation world, that is it, im not tryna learn code, im not trying to learn all of udon, i just wanna do a toggle, but of course unity & udon doesnt wanna go my way

[left fulcrum]

still unsuccessful, all tutorials not working as shown

[wind atlas]

It doesn't sound like you want udon related help since you are not posting your actual udon problems.
Maybe you want to use a solution like CyanTriggers? It's supposed to work like the SDK2, if you are familiar with that. I am not and I've never touched it, but it's supposed to help people who don't code from what I know.
Have a look at their setup video, in the first 3 minutes they show you what I think you want:
https://www.youtube.com/watch?v=RLJorzZGy-U&list=PLIoLQ-8wanr9oC3SK-2SAZ0JPXEwwljNv&index=1

[left fulcrum]

i found a working one now! ;D

[edgy ingot]

aighty, tyty

[craggy harbor]

Is there a minimum value for this that if this value is set lower than that it will reset to one? I did some test and notice these objects are still very easily accessible from a relatively far distance no matter how small the proximity value is.

[prime glacier]

Help😵

[unborn hornet]

Help with what?

[prime glacier]

Error message when I upload the world

This error stops me from uploading

【Always】Fetching fresh local config

[grand temple]

That's not an error message, it's not even a warning. It's just a log saying that it's communicating with the API

[final sedge]

o,wow

[final sedge]

I just have to wait all the time?

[sage ledge]

Is there a decent tutorial how to toggle a global respawn of objects? (Udon)

[grizzled trout]

hi, need some help with somthing. i am trying to make it so when someone presses a button everyone close to that player gets tellaported . i tried making a box with a colider that basikly would tellaport anyone who enters then sets its self to despawn but it would only send one randomplyer .how can i fix this?

[grizzled trout]

also kinda dump question but is there away to set a vareable like global? like so codes intoract with eachother?

[wind atlas]

SendNetworkCustomEvent when the button is pressed. Then in the called event, you teleport the local user.

[wind atlas]

Sorry, I kinda answered without thinking. You'd also need to test if that local player is in the trigger too.

[grizzled trout]

i do have it set that way, the problem is i need to disable it after people get sent so that if somone walks in to the area after the fact they wont get telaported with out someone having to push the button again

OOh wait ! no i think i relized i am dum!

i sware i chaged that

think i fixed it

[wind atlas]

If you've fixed it then that's good. It shouldn't be possible for a SendCustomNetworkEvent to trigger multiple times.

[wind atlas]

Also, not sure what you mean by global, but if you set a variable to synced on a Continuous script, then everyone will receive the value from it.

[grizzled trout]

like say for exsample to open a door you press a one button twice , and then another button 3 tmes and then a door opens

if that makes sense

[grizzled trout]

here is the graph for the telaporter btw

[wind atlas]

Your example can be done purely with local state. However, if you want people who join to also know about those 3 button presses, then that's what synced variables are for.

[grizzled trout]

can you show me an excample of how to do it ? i dont mind if people joining late dont get the changes

[wind atlas]

With local state? It honestly boils down to using SendCustomNetworkEvent when someone presses the button. Every client gets that event and increases their own counter by one.

[grizzled trout]

i mean how do you get the value from one script for another?

[wind atlas]

However, being able to handle late joiners is nice, so I'd recommend to check out the documentation for synced variables if you haven't already.

[wind atlas]

You can reference scripts in scripts.

[grizzled trout]

how? sorry if i seem kinda dence, just been spending a while trying to understand it on my own and a little fryied

[wind atlas]

Not sure about the best way in graph since I don't use it that much. Try dragging a script into another graph?

Otherwise, create a UdonBehavior variable.

Pretty sure there are some basic tutorials that show that.

[grizzled trout]

i tried the draging one on to the other and that dint work but i will look in to the UdonBehavior variable, thanks for your help

https://www.youtube.com/watch?v=HERcbs636Xo ok , slightly depressing how easy it is

[kind nexus]

Hello, everytime i import the latest SDK i get this errors any ideas

[dawn forge]

Are you updating the existing version?

[kind nexus]

i made a new project

[dawn forge]

It's having trouble updating/replacing a file within the sdk you're importing into Unity. Do you have enough disk space?

[kind nexus]

I should have, Ill End up deleting some files and try that out

[dawn forge]

Check these paths and delete them if they exist then try again.

The files, not paths*

[scarlet lake]

I have a problem with my world where my file seem to not let me test it but i logged in and out

and i got a new pc but i transferred my data from my old pc to my new pc, and now my sdk is not aloud to build or test

[gentle summit]

how could i make a ai follow a nearby player based on chance?

or just wander the nav?

[undone rock]

Hello, does someone know how to make a point light that follows the player around? I think I could do this using c#

[wind atlas]

You can do stuff like Networking.LocalPlayer.GetPosition()

[wind atlas]

Something like this:

int num = Random.Range(0, VRCPlayerApi.GetPlayerCount());
MoveMyAI(PlayerList[num].GetPosition());

You need to obviously save the PlayerList in OnPlayerJoined/Left

[wind atlas]

Have you used the NavMesh components before? I assumed you do since you mentioned it.

Instead of a random num, you can also just get the closest player to the AI.

[dawn forge]

Has anyone tried different sorting algorithms to see which one works best on par with the Unity frame rate and how Udon manages memory heap for this?

[fiery yoke]

When implementing algorithms in Udon the number 1 way to improve performance is to reduce the amount of Extern calls. Anything else doesnt really matter, since they are unproportionally expensive.

[unreal grail]

I love working with Udon. I have just one request...can you all please fix this typo in the Networking documentation? It's under RequestSerialization:
This node works will with the OnPreSerialization Event node.

I believe it is supposed to be "works well".

[twilit breach]

Does anyone have experience getting video players to work on Quest?

[dapper lion]

yes, what you need?

[twilit breach]

Does Quest use AVPro or Unity player? Also if you could just sort of go over any details of what you found works and what doesn't. I've heard things like it needs to be a direct link to an mp4 but not sure what else is important

[dapper lion]

avpro and unity both work, avpro is generally the recommended one, if you need rendertextures then use unity. but it depends on what you are trying to load, you could load mp3 files as music in a world via videoplayers, mp4 h.264 is usually what plays nice on quest. mpeg2 (.ts) works on quest. The main concern you should have is syncing the videoplayer too agreessively

but ofc, theres specific applications that can be done for the videoplayer for quest support so its optimally played in game

[twilit breach]

So the only syncing I do is with the initial URL and play. Basically I try to have a PC user type a URL into the input field, then when they enter it, it syncs that URL to other users and has them play the same URL locally. Works fine for other PC users but Quest users have reported issues (with the Allow Untrusted URLs checked)

Need to double check that the mp4 is h.264 but do you know of any issues syncing a URL from input field over to a Quest user? or is that something that should work

[dapper lion]

theres some slight annomallies but nothing too big other than the afk quest glitch

i would double check that the hierarchies are both the same on android and pc

[twilit breach]

I'll check that out but it is reassuring to know that its possible to enter and play URLs at runtime for Quest users. Read a forum that was mentioning it only working with links you preset in the project and got nervous

This is a good start point. Will double check hierarchy, mp4 and if it is h.264. Oh is there like a specific link that works for direct mp4s? or pretty much Google drive or VRCDN links should just work (I suppose I mean if there's some sort of special shortened version or modified version of the URLs that is needed or even causes issues if used instead)

[dapper lion]

i have yet to fully test out vrcdn, but google drive media def work

[twilit breach]

just curious, yours must have a PC user enter the URL in an input field and then it syncs that URL for Quest users? Or did you find a way for Quest users so somehow copy/paste (since they don't have keyboards xD)

[dapper lion]

vrcurlinputfields are super limiting but, my crack team of quest development figured out that you can type stuff in on the quest side via "sidequest" on their secondary devices

theres a canny about a year ago addressing this issue, but it was never fixed

https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback/p/need-better-pc-quest-udon-code-equity

[twilit breach]

Is SideQuest like a mobile phone or PC app that lets users do things for their Quest? I think I see it on Google but just want to confirm

[dapper lion]

should be both

[twilit breach]

cool cool. Thanks a lot. This has been super helpful. Going to try all this stuff out. Again thank you very much! 😁

[wide radish]

Does anyone know how to make an object follow you in your world?

[pearl tiger]

This is definitely a question for a team member, but I accidentally did a no-no and told unity to update some out-of-date dependencies. Luckily, everything seems fine minus this one error
''' Assets\Udon\EventProxies\OnAudioFilterReadProxy.cs(10,27): error CS1061: 'UdonBehaviour' does not contain a definition for 'ProxyOnAudioFilterRead' and no accessible extension method 'ProxyOnAudioFilterRead' accepting a first argument of type 'UdonBehaviour' could be found '''

I'm comfortable with editing the code, so does anybody happen to know what I'd have to fix in there?

[bleak echo]

Does udon sharp support string.Split()?

[grand temple]

yes

[simple shell]

Hey there! Is there a Graph for "OnKeyDown use container"? Like if you press the "I" Key it causes a button to get pressed in world?

[topaz sorrel]

I have a VRC pickup and I want to make it so every time you press trigger while holding it, it switches between two materials. How would I code an UDON script to do that?

[hushed gazelle]

@simple shell Check for Input GetKeyDown with a Branch on the fixed update loop (ie; GetkeyDown I == True, Set MenuBool to True/False)

If you do it on a pickup, make sure to check the Pickup is being held as well, just as an FYI.

On a different topic, is there a way to force a pickup into a player's hand? Eg; Click on Pile of Things, put A Thing in player's hand that interacted with it?

[fiery yoke]

Nope. Sad, I know.

[hushed gazelle]

Dangit, ah well.

[topaz sorrel]

I've got an UdonSharp script and I want to make it so when you use the held item it'll change materials to another material.
The material change works, only if I force OnPickupUseUp, but if I'm in game and actually use the item it doesn't change

[fiery yoke]

Make sure "Auto Hold" is set to "Yes" on the pickup

[topaz sorrel]

Alright, lemme go try that

Okay it works. Thanks!

[fiery yoke]

Yeah VRChat goofed on that one

[bitter silo]

yo guys i know i am dumb but how can i get my world to be in my bio like this

[cold raft]

if you upload a world as public yourself through unity it will show up there

(it might be hidden when the world is still in labs state)

[slow delta]

your world has to be out of the community labs to show up there

[topaz sorrel]

I've got some pickups which I need to be globally synced, except every time I add the global object sync component, I get an error in builder telling me object sync cannot share an object with manually synced Udon behaviour.
I do have a U# script attached to it which syncs the object changing material at the press of a button, but it doesn't sync the object's location

[hushed gazelle]

Set the udon behaviour to sync Continuously.

[topaz sorrel]

howwwww do I do that

because the drop-down box I'd normally press to do that is un-openable

[cold raft]

then its an attribute insie the udon# sharp script at the top of the file

an other solution, is to create an empty game object as its parent, put the object sync and pickups scripts on there, and keep the udon# script and the model or whatever it is as a child

that way the pickups and object sync will sync the position of the empty game object while the child object can still work as it always did using the attached udon# scripts

[final sedge]

Udon Behaviour(Script)➡Continuous.Entering the game is still locally visible，I do not know why

[bitter silo]

how can i do that

[indigo finch]

https://docs.vrchat.com/docs/vrchat-community-labs

[cold raft]

basicly it goes out of labs on its own, if its popular like you invite a lot of friends there it can take a few days, otherwise maybe a few weeks

[bitter silo]

oh so i have to publish the world in the community labs and wait for it to just get out of it?

[gilded shore]

i am wondering what the udon events
UdonSyncRunProgramAsRPC ObjectName :player node (6)
UdonSyncRunProgramAsRPC ObjectName :frag (0)
UdonSyncRunProgramAsRPC ObjectName :smoke (0)
do in the context of murder 4

[cold raft]

that is not something for you to know unless your trying to hack it

[gilded shore]

I had a rpc sniffer on and some guy was spamming it a lot

[fiery yoke]

Im pretty sure the console tells you that as well...

[gilded shore]

Cool

I just wanted to confirm that it has to be something with the grenade

[bleak echo]

How do I get text from a text field in UI?

This is giving me an error:

[fiery yoke]

You probably did not assign anything to uiTextInput in the Inspector.

[bleak echo]

I did, I'll confirm

[fiery yoke]

An exception also says what went wrong, you cut it off to early to be helpful

[bleak echo]

oh wait a second it got unset!

I'll try again, sry for bothering over something so silly.

actually no, still getting the same error

calling .ToString() also didn't help:

[bleak echo]

So, is it possible to read and manipulate ui text fields? I assume i should be...

[bleak echo]

Alright, so the issue was calling the method on Start().
Calling it at a later time works fine.
For my purposes this is perfectly fine. So my problem is solved.

[mighty fjord]

Strange

[bleak echo]

Yes it is.
I have a techanon pro video player in the world, which runs before anything else. I don't know if that's somehow interfering.

[fiery yoke]

Could very well be something related to the Execution Order

[bleak echo]

I know the video player has this line on it:

[DefaultExecutionOrder(-9999)] // needs to initialize before anything else if possible

It's outside of the scope of what I'm doing, but I suppose I could do the inverse on my script:

[DefaultExecutionOrder(9999)] // needs to initialize AFTER anything else if possible

well, now it's working regardless of what I do. I honestly don't know why the behavior is being inconsistent.

I'm using cyanemu, to test things, so maybe it's just acting up for some arbitrary reason

Anyway, problem solved. 😅

[scarlet lake]

Newbie question. Is Udon only programmable via the node graph interface? Can Udon be manipulated as raw text like an ordinary language? Can I separately call Udon routines in C#?

[grand temple]

sorta, you're on the right track. You can use udon with C# but it's not because udon is being called by C#, instead it's because you can compile C# into udon code

the tool to do this is UdonSharp https://github.com/MerlinVR/UdonSharp

TL;DR the graph is just the default compiler. It creates assembly code, and that's what actually runs in your vrc world. But that assembly code can be created by anything, including custom compilers created by the community

[scarlet lake]

Oh nice. So I could just write my own language ontop of the Udon VM ?

[grand temple]

if you are intimately familiar with compilers, yes

you can also just write the assembly by hand if you really wanted to 😅

[scarlet lake]

It just seems strange to ship an interface like this, and go right to visual programming, without writing some kind of language. Visual languages start looking like circuit diagrams, and become extremely complex, unwieldy, brittle, etc. very quickly.

Udon is still in Alpha though right? I guess if you've just focused your effort on designing a VM, you can delay your language implementations until later.

[grand temple]

The graph is built to be user friendly for beginners. The community-built compilers fill the needs of advanced users

[scarlet lake]

Oh I see. Maybe I'll get started with the assembly code then. Might be a fun project to roll my own compiler later

[grand temple]

I'm not sure if there's any kind of code assistance for assembly, it will be pretty painful. I really recommend udonsharp, it is the best udon programming experience right now

even if you want to move towards your own thing eventually, you should get a feel for what the current landscape looks like

[scarlet lake]

Okay will do. Thanks for the recommend @grand temple

[naive lagoon]

How would I emulate or simulate a laser light show?

[ebon lantern]

I am new to udon graph and need help creating a ontriggerenter with multiple game objects. where all the gameobjects are needed to toggle on a seperate game object. please?:)

[night viper]

I would do it with a private int. OnTriggerEnter, add 1 to the Int. On TriggerExit subtract 1 to the int. If 3 objects enter the trigger, the Int will be 3 (since each object added 1) Then you just have an event that detects when Int equals X number, then the flow continues using a branch (if) that toggle a separate object.

[ebon lantern]

Okay that makes sense. i will give it a try!

[night viper]

Here is in case you need a visual representation of what i meant.

[ebon lantern]

omg you are a blessing

[ebon lantern]

im sorry for the dumb question. but i really cange find the change even

nvm

i did it

[scarlet lake]

this is because the unity version isnt it

[elder peak]

your disk space is too low

[fading cipher]

Pretty advanced question but asking for a friend... has anybody found a way to successfully keep the player from moving their avatar at all when in Full Body calibration mode when they T-Pose?

[magic drift]

Hey, I'm using the "canvas" prefab/script to make info boards but I've noticed they are always visible
How can I make the environment block them?
or if it's easier make it so when you go a outside a certain range they disable?

[night viper]

Did you test it on game/play mode? I remember a bug where UI canvas/text would be visible through walls, but pressing PLAY then exiting would fix it.

[magic drift]

I have looked at it in game but I didn't test for if it was visible through walls
I'll give it a test now (in play mode)
Always forget how misleading the Unity editor can be

[magic drift]

Shouldn't this be in #full-body-tracking not #udon-general ?

[fading cipher]

No because it’s an udon question 🤔

[magic drift]

Apologies it seemed more like a FBT, avatar, or just game related question than Udon

I think I saw a head tracking prefab I can check if it tracks based of off bone or what
because maybe you could use that to move the avatar based on how the player is actually moving?

[fading cipher]

The issue is more specifically that when a player is in full body and goes into calibration mode, even stations that keep the player still don’t keep them still

They can move their avatar around outside of the station and break things

[magic drift]

I meant move the avatar inverse to how the person is moving when calibrating

Because I presume the way they're moving their avatar/capsule is by physically moving

[magic drift]

Thank you

[fading cipher]

I have just received news from said friends that the issue is specifically that we need to keep them in their playspace origin, and moving around irl then teleporting them back to the station wouldn’t magically tell the game that their irl position is now the center of their playspace

[magic drift]

Mhm

Good luck

[hushed gazelle]

Just a quick sanity-check; If I turn on a collider with a trigger area in it, it should immediately detect the players standing in its area correct? (Assuming correct Layer, OnPlayerTriggerEnter, etc)

[wind atlas]

Could you use the head tracking position to teleport the player to the right location?

[fading cipher]

Teleporting the player doesn’t change the distance from their tracking data to their playspace’s origin

[wind atlas]

The idea I had is to fixate the players position to a specific point in the world by using the head. Hope that makes sense. But yeah, I don't know your issue, just throwing out ideas.

[torn pendant]

How do you make custom delayed play Local ONLY.

[hushed gazelle]

Set the recipient to the local player.

[torn pendant]

How?

[hushed gazelle]

Wait, sorry ,that should be local by default. Thought it said Network event.

[flint urchin]

Yeah, that in itself is local only.

[meager herald]

Does anyone have a recommendation for a video tutorial series for a new world creator to go through that will help with essential udon things such as toggles for items, lightings, mirrors, PP settings, etc?

[indigo finch]

The most common thing in vrchat worlds is toggling on and off something, to which Vowgan's tutorial has helped many: https://www.youtube.com/watch?v=ibDu0dCeUE8.
That being said, if your really trying to learn udon to make a full on game (not just sdk2 game), then you'll have a hard time going off vrchat tutorials alone. In that case, I would recommend playing around a bit in standard unity for that, and bringing your knowledge over to vrchat udon. A basic knowledge from something like the 'c# survival guide' should get you to the stage of being able to read the documentation and understand what they're saying

also, feel free to ask here if you get stuck ^^

[meager herald]

Awesome, I'll check this out! I'm mostly just planning on making simpler worlds that are to hang out in and might have some prefab games in them. No plans at the moment to make any custom games from scratch. I just want to make sure I can quickly and correctly make toggles, menus, video players and such that people can use in the worlds.

[indigo finch]

luckily, for most of that you just need toggles. I think he also did a tutorial on ui's so check that out if your after that.
Something to note with prefabs is that many need udonsharp to run, so be sure to import that as well ^^

[copper mortar]

So, I haven't made worlds in a long time...
How do I make triggers again?

[copper mortar]

https://www.youtube.com/watch?v=ibDu0dCeUE8&ab_channel=VowganVR
I followed this tutorial, but I want it to turn itself off after it's done. Basically I want the trigger to activate a sound, turn off, and activate a sound again.

[meager herald]

Thank ya a ton!

[copper mortar]

https://gyazo.com/4fbdf730647c6d93074e7cf29cdc9efe
Basically I want to create a trigger that will turn on an audio source for a bit before turning it back off. The trigger is what causes it to turn both on and off. How do I do this?

https://gyazo.com/16ad51f9dcec1faa7602c701b3beafc3
This is what I have for the Udon Graph. How do I make it to where the trigger will turn the object off afterwards???

I want it to play the audio source fully before turning it off. Again, how do I accomplish this?

[scarlet lake]

how would i make a toggle button where i can turn off a collider

[indigo finch]

Your probably better off just playing the audio sound: https://youtu.be/cQ3hWKY-NiA

As for your question, there is a 'send delayed in seconds custom event' node (or something along those lines). Just send a delayed event that turns it off afterwards

[indigo finch]

If you know how to toggle a gameobject, it's exactly the same, just instead of a gameobject.setactive node its a collider.Enabled (or set enabled...) node instead

[junior coral]

Does Someone have a Script oder asset that can Toggle an Object on and off and also can Move same Obejct only on the Y Coords from 1 to 100 in 0.5steps. Prefered a Slider or an + - Toggle

Or a scipt i can put in Object X and it Scan the User for his Viewpoint Position then Adds 0.5 and Moves Object X only on the Y Coords.

Does anyone know how to to add multiple UdonSharp Video Player screens/UIs to the same system? Basically i want the video player system to display on multiple monitors, and have multiple input UI's too. I realize it can only play one video at the time, that's as it should be.

[indigo finch]

Im not that familiar, so take this with a large grain of salt, but I think one of the video players can output to a rendered texture. If so, you could put that rendered texture on a material, and that material could be placed on many screens. The buttons could be done by firing events to a script that manages the video, and for ui input... dunno. you cant have it change a 'master text' box for the url afaik, as vrchat's superprotective of making it user input only for urls, but perhaps you could send an event to say 'hey, grab from this text box' instead.
hope that helps. if not, hopefully someone else can ^^

[junior coral]

the Wolfe Video player should be able to do that if u just Copy the Screen Layer on Other Monitors
or copy only The TV, speaker and controller.
if everything is still in the same roots TV tree they should be linked.

[wind atlas]

I'm not that familiar with it either, but I'm pretty sure you can turn any video player into a render texture by putting the output screen somewhere else in the world and point a camera at it. Theoretically that might work too.

[meager herald]

I'm trying to toggle off particles in my world with a simple button and it works for all of my particles except for one system that I have set up. The others don't have and children objects and work fine, but the one that has a few children particles under it does not toggle off with my "gameobject" toggle.

Using "target.SetActive(!target.activeInHierarchy);" for my toggle for the particles. Is this even the proper way to do so, or is there a better way for me to toggle these particles?

[valid basin]

with the latest version of USharp Video Player it was a breeze

other than the audio sources, i had to make a trigger that teleports those along with the player

[broken bear]

Is Ondeserialization event ignored if there are no synched paramaters on an udon behavior?

[fiery yoke]

If there is nothing to be deserialized, OnDeserialization will not be called :P

[broken bear]

got ya, I as using it as a bypass to avoid sendcustomnetwork event, I'll stick a random variable as synched

[copper mortar]

I have a complicated task I want to do

Basically, I want to trigger a button that will make the animator of an object become active and play the animation that’s on it. That part is simple. The next part isn’t. After the animation is over I want it to enable an object and not turn it off. I also want some music to play and then turn off. How the heckie do I this this?
Also, is it possible for this music to override all other music in the game until it’s over?

[grand temple]

if you have an animator on the same object as an udonbehaviour, the animator can send an event to the udonbehaviour with animation events

[copper mortar]

I know very little about Udon, but I’ll try

[copper thicket]

how does one Set the VRCUrl with a specific string as aparently new VRCUrl(string url) is not exposed to U# nor there's Set method

[grand temple]

Udon is not able to create VRCURLs at runtime. You can create VRCURLs in editor with a public VRCURL or you can get them from user input with a VRCURLInputField

[copper thicket]

hold on, then VRCUrl is syncable then?

[grand temple]

yes

[copper thicket]

aight

[indigo finch]

Here's my two cents. I think you need to break up the problem into different parts. First, you want to play an animation, which could be done by a 'animator.setTrigger', or in your case, just toggling it on. Provided the animation file is set to not loop, it will stay at whatever the last frame had and you can just ignore it from then on. Then also on the script that toggles on the object, you want to tell an audio source to play a sound. there is no need for it to be toggled on or off to do this. A simple 'AudioSource.play' is enough. I made a tutorial on how to play a sound a month ago, so go see that if you need help. If you want the audio to be delayed, you could always use a 'send custom delayed by seconds event' node to delay it.
As for the music overriding all other music, it depends on what you mean. If you just want it to play the audio regardless of where or how far away the object it, then simply disable specialization on the audio Source. However, if you were instead wanting to mute all other sounds in the world, then I only have a painful solution. There might be a better way of doing this, but you could have a public variable 'audioSource[]' array with all the other sounds in the world. Then you could use an 'AudioSource.pause' node, do a 'send custom delayed by seconds event' node (set to how long the sound file is), and after the delay it does an 'AudioSource.UnPause' node to resume the music.

[copper mortar]

Nope. Not even gonna attempt it.

[feral merlin]

Quick question

Is there a function to check the avatar id of someones avatar?

I have a very cool feature in mind

[scarlet lake]

my mirror button isn't toggling in game

i have 3 different meshes, i have my udon graph linked to my hq mirror which is off by default

ive read and watched different videos and im just getting confused and frustrated on why my toggles arent working

[grand temple]

what does the inspector where you've added the udonbehaviour look like?

[grand temple]

you need to give it a collider

[scarlet lake]

just a mesh one?

[grand temple]

no, box collider should be plenty

[scarlet lake]

does the size matter

[grand temple]

yes, that's how big the interactable will be

but it should automatically fit around the mesh

[scarlet lake]

so is that graph fine to use on my low quality button as well and just add the collider to the text?

[grand temple]

yeah it would work

though as it's set up now, you can turn on both high and low at the same time. Ideally you'd want to add another part that disables the opposite mirror so only one can be enabled at a time

[scarlet lake]

oh how would i do that?

[grand temple]

add another public gameobject variable and always setactive false

that way the HQ button always disables the LQ mirror and the LQ button always disables the HQ mirror

[scarlet lake]

so would i add the mirror then set activate then unary negation?

[grand temple]

you want to always set it to false so there is no reason to provide anything else

also you can reuse this same graph on both buttons so I would not recommend naming the variables LQ and HQ.

you can call them primary and secondary or something

that way on the LQ button, the primary is the LQ mirror and on the HQ button, the primary is the HQ mirror

[scarlet lake]

im sorry im new to udon and the words arent helping me @.@ im better with viusals

[grand temple]

doesn't matter, just semantics

[vivid eagle]

I think this is the channel to ask this... I'm having a problem in Unity that's not letting me Build&Test my world. When I Test it, it loads normally and for a split second I hear the audio of the world play but it reloads and then I'm sent to the VRChat Home. It doesn't show there are any errors, except when I try to Build & Publish with the error being this:
"NullReferenceException: Object reference not set to an instance of an object
VRCSDK2.RuntimeWorldCreation.Start () (at Assets/VRCSDK/Dependencies/VRChat/Scripts/RuntimeWorldCreation.cs:82)"
I tried searching online for answers but couldn't find anything or anything that I recognized as an solution. I'm pretty new to all of this kind of stuff.

[autumn oriole]

is there a way to play a video which I put in the project? Not with url

[junior coral]

i still search an Slider that can move an Set object on the Y Axis.

[indigo finch]

Are you trying to upload an sdk3/ udon world? perhaps one of your prefabs was made for sdk2 and not sdk3. sdk2 is completely incompatible

[indigo finch]

Here's my rough explanation on how to do it. Have an udon script with a Vector3 variable of its original location. Also create a float variable for the slider to change, and a public uiSlider variable for the slider itself.
In the graph itself, create a custom event that when called, grabs the public uiSlider into a 'uiSlider.getvalue' node, and make the float value equal it. Then you want to grab your Vector3 and then grab the y value, and then add the y value to the public float value (that now equals your uiSlider). Then you remake it into a vector3, and that is now the new location for your object. You then want to put the modified vector3 into a transform.position node to change your gameobject's position to the new location.
Afterwards, you will also need to, in unity and on the slider itself, hit the little + on the slider component, and drag and drop the script gameobject into the new slot. Then with the dropdown, select udonbehaviour and select send custom event. Then you give it the name of the custom event (Case sensitive) on your script that updates the float variable

So yea, not the easiest to explain in text, though its a lot easier in practice

[vivid eagle]

That would make sense. Wish it said which asset it was, but thank you. I'll make sure to double check my pieces.

[vivid eagle]

Doesn't seem to be the problem. I deleted prefabs that I assumed was causing the issue and it doesnt change anything. I added Christmas lights into my project after having a successful play test, and after adding a few I was having issues with the SDK and Udon Sharp. I saved assets and the scene of parts I knew for sure werent the problem. I also realized, I think this builder screen is a little messed up. It used to show a lot more information...

[vivid eagle]

Idk if that would be related to my problem, but its something I noticed after I could no longer Build&Test

[unborn hornet]

Calling RequestSerialization as a non-owner is treated as a NOOP correct?

[grand temple]

It does nothing, yes

But it does log a warning or error

[unborn hornet]

Alright then.

[distant prairie]

I'm a beginner at udon and programming at a hole but there is this one thing I really want to make (a card game, both as a world and on an avatar) but I can't figure out how to spawn/set active a random object. i tried pure c# couldn't interact with the button I tried both udon and cyantrigger can't figure out how to tell it to give me a random object just the one specific object. and I couldn't find any tutorials on it on the web

[grand temple]

You can use a vrcobjectpool and shuffle it before trying to spawn

[distant prairie]

for the pool do I just put an array into it or do I have to put in every single object

and where do I find the shuffle node

[grand temple]

You can put in all the objects at once if you select the object with the pool, then click the lock button top right. Then select all your objects and drag them into the array all at once

And the shuffle node can be found if you search for vrcobjectpool first

Or if you don't know what category something is in you can always press tab to do a full search

[meager herald]

How exactly would one make a toggle for particles in a world? I can't get my button toggle to toggle off all of the particles in my world and I'm using the button to toggle off/on the game object in the hierarchy.

Actually nevermind I figured it out.

[carmine fiber]

is there a good udon tutorial playlist anyone can recommend? something that covers the basics but doesn't just cover the basics

[hushed gazelle]

The better way would be to do this through an animator and put each Mirror option on a different int value. Eg; Off == 0, Avatar-only Mirror == 1, HQ Mirror == 2. That way you can scale it and they can never overlap.

[grand temple]

if you want to have multiple mirrors you can just have an array of objects to disable

adding an animator to this significantly increases the number of moving parts

[vapid bough]

So, Im in sdk3 with udon sharp uploaded and my shit just freaks out

More errors include Udon behavior and Networking

[vernal maple]

Quick VRC Pickup question. Trying to discover a quick and easy way to detect which hand the item is in, and what that item is. So far I've got GetPickupInHand() for both left and right and two separate if statements. Is there something quicker?

[brazen epoch]

Is there a standard way to check if 2 players equal each other? I'm comparing VRCPlayerApi.playerId, but I'm not sure how that works in local test envs

[wind atlas]

What are you trying to achieve? If you have the pickup instance already, you can call "currentHand" and it will return an enum which can be None, Left or Right.

[wind atlas]

Looks like you are missing some files. Try making a fresh install.

[wind atlas]

You can compare the player instances themselves, or you can compare the playerId, both should work if you want to find the same player.

[scarlet lake]

how do you teleport 2 friends lmfao

[indigo finch]

Unless your using cyanemu to play it in the editor, player id should work

[vapid bough]

Has anyone used Toly's combat system before?

[fallen chasm]

This might be a stretch given possible exploits and what not, but can Udon manipulate the VRC Scene Descriptor? -- I'm experimenting with something and I'd like to adjust the reference camera settings.

[fiery yoke]

No you cant access/modify the player camera.

(sorry wrong reply)

[fallen chasm]

m'kay -- I figured that was the case. Something like that could be abused pretty easily.

[vapid bough]

I fixed this already mb

[fiery yoke]

Not in terms of security. Only stability (or more "playability"), which isnt really a super valid argument, since there is enough other ways to ruin that.

Im not sure why you cant do it. But you cant.

[fallen chasm]

hmm... perhaps I should extend my question to include my goal. Maybe there's a better way to handle it.

I'm experimenting with a concept where players (non local) are only visible in a mirror. Haven't had much luck with baked occlusion. Figured I'd turn towards udon to see if I there was a more reliable way, but without access to the camera I'm not sure.

(hiding the local player from the mirror is as easy as editing the culling layers, so that half is solved)

[rain furnace]

anyone know where/how to get this

[trail mesa]

So I made a Tv and got buttons for url, play, and a slider for volume. its all works fine but when me and my friend went to watch something and it was only locally changing. Now I need to figure out how to make it global for the TV, Url and play buttons while keeping the volume slider local. does anyone have a good video/resource to help me out? (preferably a video)

[carmine fiber]

anyone know a good udon playlist that covers the basics and goes into some more advanced stuff?

or a beginner one and a more advanced one that can follow from it

either way

[obtuse agate]

You might attach an extra camera to player head which doesn’t render Player layer, and overwrites the default camera view

[vapid bough]

Does anyone know a working combat udon system for sale or public?

[low bear]

I haven’t seen any free ones, but most of em aren’t too expensive. Plus there’s tutorials on YouTube

[quasi harness]

yeah i have it now, it works ty

[pearl mantle]

Which streaming formats does VRC support?

I tried rtmp:// but i get video error

[indigo wagon]

http/https

and it ither needs to work with YTDL or be mp4

and if its not an officially supported source you need unknown sources on

[pearl mantle]

reddit says DASH is supported by avpro https://www.reddit.com/r/VRchat/comments/kw4dci/showing_hlsrtmp_stream_in_world/

[indigo wagon]

try just enableing unkown sources then see if that helps

also cyanemu is buggy with video players

also IDK how it works but i belive it would need to be acsessed from external servers/clients and that says you need to make it into a HLS stream

[candid frigate]

How do I multiply two Vector3's together?

I'm trying to move a object randomly around the map but locking it on the Y axis.

[fiery yoke]

Should be Vector3.op_Multiply

[candid frigate]

This?

[fiery yoke]

Yeah. you cannot multiply two vectors together. You can multiply them component wise though, which is called Scale. so I guess you mean that

[candid frigate]

Ah, that's what I was looking for, every game engine I've used just bundled that in with the vector multiply operator. Thank you!

[vapid bough]

Anyone know where I could find a udon pvp and or combat system?

[scarlet wigeon]

I just started getting into Udon# and before I waste even more time in searching for the impossible: Is it possible to fetch api data over https with udon# or over some script for vrc worlds, or does everything has to be available in the code already?

[fiery yoke]

Short answer: No.

[wind atlas]

Only http requests possible are from the video player. It's very limited though as it's not intended for that.

[scarlet wigeon]

Oh okay. So that means, when building an UI you would have to pre-load in an hardcoded way the data you need

[valid basin]

I want to change a player's SetVoiceDistanceFar and so on by interacting with a button. so far it seems like all the examples use a box trigger for area, but i cant find how to use a button interaction instead.
i have a script for the button working, but i am not sure how to apply the effect on the player. Anywhere i put VRCPlayerApi player seems wrong

does anyone know how to do this?

[wind atlas]

Your question is a bit vague, pvp can mean many things. Imo you'd want to make one yourself to make it unique. If you really want a prefab, there is this: https://github.com/Toly65/UdonCombatSystem

[vapid bough]

So I tried setting up this system and could not get it to work

[scarlet lake]

Sometimes at night When I join it stops me from joining VR chat and Take me back to the main screen do you have an explanation why?

[vapid bough]

Do you have any pointers to get this to work? I would follow the instructions and no damage would happen.

[wind atlas]

Haven't tried it myself. See if there is an example scene, ideally it works and shows you how to set it up.

[vapid bough]

I set up the basic scene and the damage refuses to work

[forest harness]

[wind atlas]

That is unfortunate. You need to debug it yourself then.

[valid basin]

any thoughts about this?

btw im trying to apply the effect to the person using the button

[wind atlas]

Afaik Interact only fires locally, so you can use Networkin.localPlayer

[scarlet wigeon]

Is everything supposed to be in the same class/file in Udon# or is it possible to split code to multiple classes?

(Accessing a class of another file, am I doing it wrong or is it indeed not possible to "import" stuff?)

[grand temple]

Not in the main release at the moment. U# 1.0 beta allows for inheritance and static methods however

[grand temple]

The tricky thing is that you could easily just set the local players voice distance but that's not going to do anything because voice is all about how it's received, not how it's sent. So you need to instead communicate with all the other players and tell them to set your voice instead. To do that, the easiest way would be to take ownership and set a synced bool. Then ondeserialization (this is an event that happens when other people receive synced data) you get the owner of the object and set their voice settings appropriately.

The only problem with that is only one person can be the owner at a time, so you need to make sure you clean up and reset the voice of the previous person when you detect onownershiptransferred

[scarlet wigeon]

Okay, thanks for that info

[viral frigate]

Oh almighty masters of Udon/U#. ^^

I'm in search for answers to a pretty trivial question which I can't find an answer to.
How can we alter the parameters of the Player Camera?

Whatever I try the values from the MainCamera passed into the VRC_Scene_Descriptor gets reset to standard values in CyanEmu.
I'm trying to change culling mask parameters, FoV... on the active Player Camera.
Any Udon Script or Animator/Animation I put into the Main Camera just gets ignored.

What piece of the puzzle am I not seeing here? 😄

And the culling mask node in Udon just takes an Integer as Input. I couldnt find any information on what that integer does. Is it the array order of the layers? How can I assign a toggle to it? D:

[fiery yoke]

You cant.
Me and a few others usually use a technique we call "Player Camera Override" where you renderer a Camera after the actual Camera renders, but there is a lot of gotchas regarding this and its not officially supported.

[viral frigate]

Ahhh I see thank you 🙂

[indigo finch]

Depending on what your doing though, there are some shaders that seriously mess with the camera, used on vrchat avatars. A bit of a longshot perhaps, but maybe worth a look

[viral frigate]

Thank you for the suggestion. Unfortunately I really need those juicy culling masks accessed on the Player Camera 😄

Or my custom camera as the player camera. All I can do is activate the custom camera in Unity/CyanEmu. But that doesn't help since I dont even know the Player Cameras name or anything that is created on spawn :/

[smoky saffron]

What void do I use if I want a U# program to run every time I click a toggle?

[native rampart]

Is it normal that the VRCPlayerApi object passed to OnPlayerLeft always has a playerId of -1?

[ionic pike]

Can't use VRCSDK in any fresh project. It's broke; missing semicolon in one of the scripts, fixed it myself (how they overlooked this idk), now getting another compile error. I don't have the time or patience for this stuff.

Assets\Udon\Editor\ProgramSources\UdonGraphProgram\UI\GraphView\UdonGraphWindow.cs(4,30): error CS0234: The type or namespace name 'StyleEnums' does not exist in the namespace 'UnityEngine.UIElements' (are you missing an assembly reference?)
Fresh project. Nothing in it. Unity 2019.4.31f1. Imported latest World SDK3.

[ionic pike]

Think I figured it out; apparently I imported an old version of the SDK from earlier this year and didn't realize it.

[wind atlas]

Apparently it's known bug. And you have to call playerId ~~in OnPlayerJoined ~~ anywhere on that player so it keeps the right value in OnPlayerLeft. Only found out recently while checking out the code in https://github.com/CyanLaser/CyanPlayerObjectPool

[native rampart]

what do you mean by "call playerId", just getting the value?

[wind atlas]

Yep

[native rampart]

aha! I'll try that, thank you

It worked!! Thank you so much

[native isle]

I have a question

In vrchat, what is the normal way of starting a conversation

Like do you join in on random conversations or do you go around with a friend

[hybrid canyon]

that would depend on one's mood which of the two and like how many friends you have to Join one of their conversations instead of random folks

[viral frigate]

The only thing an actor owes his public is not to bore them
~ Marlon Brando

[native isle]

I don't get it

[viral frigate]

You can start listening and chime in in what people might be interested in if you can contribute to the topic.

Has anybody figured out on how to render your custom camera over the player camera?
If I enable the custom camera in Udon and set its Depth above 0 it works in CyanEmu/Unity but not in VRChat.

How can I set its priority above the player camera? :>

[native isle]

Oh

[hybrid canyon]

and also I would note this is the channel for talking Udon General Channel might be a better spot for a conversation tips

[candid frigate]

I think I'm missing something pretty basic here, but I'm trying to make grenades that when held, light their fuse when you down-press the trigger, then are automatically thrown when you release.

But I think I'm using the wrong events for to detect trigger down and trigger up. I think the game usually calls the binding "Use"

[native isle]

Idk what udon means I just thought this channel is just a general questions chamnel

[candid frigate]

Udon is VRChat's visual scripting language, this channel is for asking for programming help.

Also, does Debug.Log work for the log in game that you have to use press Shift+`+3 to open?

[candid frigate]

Also, is there a way to debug a running game instance in the editor? It would be great to be able to step through and set breakpoints? Or at least be able to trigger player controlled events in the editor

[glass shoal]

real question here: how the hell am i supposed to approach making a world with udon?

[indigo finch]

if the interaction text is null, then vrchat will display a placeholder 'use' in it's place. I saw in Vowgan's latest video, stating that they added the ability to change the interaction text via udon, but I haven't had any luck getting it to work. Might only be on the beta version right now

as for what the script, I'm a little lost as to the use of 'OnPickupUseUp' going to a pickup.drop node. An 'OnDrop' event node may be more appropriate in your use case

[grand temple]

could you clarify where you're at? Like have you installed unity, have you installed the SDK, etc?

[glass shoal]

i have unity, and i have the SDK
ive made a few worlds previously with SDK2 but udon seems very daunting

[mighty fjord]

Interaction text isnt implemented in U# yet as it needs to update to account for this Udon change iirc

[indigo finch]

interesting... I haven't gotten it to work for udon graph either

[grand temple]

have you tried watching some tutorials like this? https://www.youtube.com/watch?v=8gXzBTqlP6I

[glass shoal]

thanks, that was a tutorial on how to drag a unity package into unity, very helpful (it wasnt)

sorry, im very frustrated

[grand temple]

that's just the start of a whole playlist

[vague radish]

What do you want made then?

[grand temple]

there are also plenty of other tutorials

[vague radish]

There are tons of tutorials for buttons mirrors and other basics

[glass shoal]

I dont wany to do basic things though, i knew how to do more advanced things in SDK2. but were not supposed to be using that anymore.
but im not a script genius with programmer socks. so how would you suggest i jump back into things, i heard there was a add on package that made it more like the flow of SDK2? do you guys know what thats called?

[grand temple]

that's called CyanTriggers

[glass shoal]

ok thanks... i will look into tutorials and i will checkout that

[grand temple]

if you ask some actual questions we can give you answers, but I really don't know what you're looking for or what would help you

[gray lagoon]

I can't join my OWN world

I made it super simple for a test world and it shoves me back home WTF???

[grand temple]

could be one of several things.

Do you have a spawn location defined properly in the VRCWorld?
Is the spawn location above the respawn height?
Are you using the correct version of unity? (2019.4.31f1)

If those are all good, taking a look at your log would help

[gray lagoon]

Ok, so I have spawn point yes, but can't load into the world

Also I have the correct version

[gray lagoon]

Also I don't know about coding so the log is chinese for me///don't know what it means.

[gray lagoon]

Not really chinese

[candid frigate]

I was trying to make sure the grenade gets dropped when the controller trigger gets released, but you're right, I have autohold off, so I can just use OnDrop. What about the console, is there any way to see that ingame?

[candid frigate]

Are there any errors in the log?

[gray lagoon]

Lemme c

[gray lagoon]

I really wanna make my own world, this is pathetic!

[gray lagoon]

No errors, just respawns back home

[candid frigate]

How are you launching into your world? By pressing Build & Test?

[gray lagoon]

Yes

[gray lagoon]

Or by the game itself

[candid frigate]

And you've set your spawn point in the scene descriptor?

Is there a collider underneath your spawn? Double check the transforms?

[gray lagoon]

Actually I added a Cube as the Spawn point

[candid frigate]

And set it as the spawn point in the scene descriptor?

[gray lagoon]

I have a Plane + a cube that I make the scene discriptor

[grand temple]

it can definitely cause problems if your spawn point is inside a collider

[candid frigate]

Try removing the cube's collider

[gray lagoon]

ok

[gray lagoon]

How do I remove a collider?

[gray lagoon]

Is it box collider?

[candid frigate]

Yes

@candid frigate It's still not working.

[candid frigate]

Maybe move the plane further below the cube? I have no idea

[gray lagoon]

I'm just gonna use Udon default

[pearl tiger]

Anyone know where I could find some info how how to make a 'trigger' for items being held like a gun or flashlight? I'm using U#

OnPickupUseDown?

[candid frigate]

If you have object with the pickup component, there's an even called "OnPickupUseDown".
This is partly from the BattleShootingVRC world's source

    public override void OnPickupUseDown() {
        /* Fire Messeage*/
     SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, nameof(WorldFire));
    }
public void WorldFire() {
// Handles raycast and hp
}

Not that I'm aware of, though I believe vareon's UdonEssentials had a in-world menu prefab that shows console, never tried it myself though. Would love to know if it works or if you find a better one. That being said, you could always dump debg.log messages into a text object instead

[candid frigate]

Thanks, I'll look into it!

The RShift+`+3 menu does show the Debug log output. There was something else wrong with my object so my script wasn't working

[vivid eagle]

How would I make a single button cycle using Udon Graph? I have a button that I want to cycle from Full, to Moody, and then No light, back to Full

[candid frigate]

You could use an array a of strings (or an enum if Udon supports that) and keep track of which index you're on, and set the button text and lighting by watching the onChange event for the index.

[distant prairie]

can anyone tell me how to fix this

UdonSharp] Assets/scripts/Testanor.cs(49,38): Udon runtime exception detected!
An exception occurred during EXTERN to 'SystemInt32Array.__Set__SystemInt32_SystemInt32__SystemVoid'.
Parameter Addresses: 0x00000005, 0x0000000D, 0x0000000D

Index was outside the bounds of the array.

[grand temple]

The error is pretty straightforward, you're accessing the array at an index that is out of bounds. Like if your array is length 5 and you try to set a value at index 10, you'll get this error

[distant prairie]

ok

[grand temple]

you'd have to share a bit of the code if you want more help. Notably, how is the array created and how are you accessing it?

[distant prairie]

https://docs.google.com/document/d/1QYcr8yWNjeTc_1QZ4QqQ9LaanPpMgYymevkLKjQcMWM/edit

heres a bit of the code

I also marked the line

[grand temple]

ah, you're iterating through it with while (counter != decksize). That means when it gets to the decksize, it will be out of bounds because the last index is always 1 less than the length

you should use counter < decksize instead

[distant prairie]

aha ok

[grand temple]

also, a for loop is more appropriate than a while for this situation. You would create it with for (int i = 0; i < cards.length; i++)

[distant prairie]

is i a generic term you used or is it a offical c# term?

...

never mind

just figured it out

[grand temple]

It's just a variable that is being defined

you could also do for (int counter = 0; counter < cards.length; counter++)

the first is a space for you to declare a variable, the second is a condition where it will keep looping as long as it's true, and the third is an operation that happens every loop.

[distant prairie]

still not working

unity says it's the line beneth it

CardsOrder[counter] = counter;

[grand temple]

it's weird for counter to be a global variable, are you sure that's necessary?

are you sure it's not getting set to something like -1?

[distant prairie]

the counter is private

[grand temple]

ok that's fair but it's still very weird

I guess you could try debug logging counter and decksize at the beginning of the loop

see what their values are right before it crashes

oh also, are you sure that stateofcard is the exact same length as cards?

that could break it if they're not

[distant prairie]

... that was the problem

thanks

[scarlet lake]

quick question whats the difference between release and dev for sdk sign

[keen bison]

hi guys is it here to message if we have problem with vrchat launcher ??

[dreamy gorge]

Is there any way to stream audio from the web? If i can just upload my files somewhere and have the world stream them that would be better

these sounds are taking up lots of space

[fiery yoke]

Can you show what you mean? I dont understand what youre talking about

[fiery yoke]

No. You can try #user-support-old or https://help.vrchat.com/hc/en-us

[fiery yoke]

You can upload them to a CDN and then use the Video Player.

[keen bison]

thank you i did and i'm waiting a response @fiery yoke

[dreamy gorge]

sounds about right, thanks

[fiery yoke]

I've never seen/noticed that before. What SDK version are you on?

[scarlet lake]

newest one

[fiery yoke]

Hmm...interesting. Not sure if that was there before. Might have been a change, or a mishap. ¯_(ツ)_/¯

[scarlet lake]

who knows

[fallen chasm]

I'm not sure how to go about asking this, but I've got a UI slider ... and I want to use it to control a specific property in a material.

these don't work, but that's where I'm at with it

Is it possible to target/change the value of a property in a custom made shader?

or should I put together a blend tree animation and adjust that instead?

[obtuse agate]

It’s been there for years. Just use Release. Dev option is for internal testing

[scarlet lake]

havent really been playing for that long so

[obtuse agate]

You are using “get material” instead of “get sharedMaterial”. The former will instantiate the material and change float properly on that instead. It might be the cause of your issue

[fallen chasm]

swapped it out -- no apparent change in behavior

Oh, I've also got a problem where the slider just snaps between 0 and 1 in playback... but I figure that's unrelated to udon... Still, if anyone knows why that might happen I'd love to get it fixed. 😛

[wind atlas]

How are you testing if the change gets applied? Maybe you could expose the float on the shader and see if it changes?

[wind atlas]

Also, disable whole numbers so it doesn't snap.

[fallen chasm]

whole numbers is disabled :/

and here's my shader

trying to manipulate the Hue value there

which is "_Hue" in the shader code

do I target it by the visible name instead?

hmm

[mighty fjord]

You should just use the internal name in the shader

[fallen chasm]

oh hek... I just realized

the shader is 1-360

[wind atlas]

That's odd then.

[mighty fjord]

Oooh, for the slider?

Not 0-1?

[fallen chasm]

degrees of rotation /shrug

I'll adjust my max

dang... still just snaps to either end

I wonder if the issue is the slider and not the graph

yea, something's up with it... I removed the udon behavior and it still just snaps to either end. It'll be hard to properly test until I solve that.

ah yiss

got it working (by deleting and remaking the slider)

but only if the target object has one material

alrighty, so... this works:

but only when the object has a single material

don't suppose anyone knows how I might target a second material?

[wind atlas]

That's because get material returns only the first, there is an array version

https://docs.unity3d.com/ScriptReference/Renderer-materials.html

[wind atlas]

Yep, gotta iterate over it using a for loop

[fallen chasm]

yea, setting it up now

👍

feels like I'm missing something

yea... gotta get the instance into the set float

[wind atlas]

You get the index, use that to get the value from the array

[fallen chasm]

oh crud, not length though

[wind atlas]

This is the point where I'd switch to U# btw, I don't think you can even do advanced things like break a for loop

[fallen chasm]

it's probably gonna sound crazy, but I do front-end web stuff for a living, but have a more visual brain... so I kinda prefer nodes when doing hobby stuff

[wind atlas]

Looks about right. Btw, did you mean earlier that the shader value snaps to whole numbers or the slider number? It could be that the shader value is an int. Then it would make sense.

[fallen chasm]

dang... still not working, gonna retrace my steps here and see if something isn't named right

_Hue ("Hue", Range(0,360)) = 0

suppose that's an int

but the slider was just snapping between 0 and 360 and nothing in between

I ended up duplicating a working slider and deleting the one I had -- somewhere along the way I must not have checked a box /shrug

perhaps I should switch this back to 'get sharedmaterials' ?

[wind atlas]

Now that's odd, but I'm glad it works now.

I think shared material won't work because at runtime, your meshes get an instanced version of it.

[fallen chasm]

yep, it just errored XD

alrighty, back to get materials...

[wind atlas]

It should still work, the difference is that you are affecting EVERY mesh using that material in the scene. Maybe you didn't get the array version?

[fallen chasm]

so... I just swapped my object for a single-material test cube

and it works

shouldn't this only be targeting my "Near" mesh object?

maybe... it's because it's static?

for the sake of info, this object works:

[fallen chasm]

only one mesh in the scene uses the material -- it just happens to also have three other materials

[unborn hornet]

If you only want to update the property on the first just one mat, you shouldn't need the for loop.

[fallen chasm]

technically second, but it's index 1 😛

[wind atlas]

Yeah, just in case you decide to reuse that material. About the static batching, I have no idea.

[unborn hornet]

It'd be MeshRenderer-> get materials -> Get (target index) -> SetFloat (desired value)

[fallen chasm]

back to what I originally had

[broken bear]

Do we have access to scaling humanoid bones directly or do we need to use station animation overrides

[broken bear]

Can you feed in the material as a public variable and just access its properties that way directly

[fallen chasm]

I think it's working... I'm watching the value change in the inspector, but it doesn't appear to effect the contents in the viewport. This might be a shader issue rather than a graph problem

so confusing

[fallen chasm]

I don't have an answer for you, but I just imagined touching a candy like button and suddenly having a tiny hand...

!!!

it works!

in game

the hue thing

doesn't look like bone scale is exposed

but hey, you could maybe make someones head spin around

[broken bear]

Set Transform?

[fallen chasm]

I'm having trouble finding any 'set bone' options -- just the 'get' options

[unborn hornet]

Player object is protected, you can only retrieve the position and rotation. Cannot set them.

[zinc robin]

How do I make it so when i add vrc pickup (script) that in the word I can see what people are picking up, seems like its on local now and no one can see what someone is holding, how can i fix this

[fallen chasm]

add the 'vrc object sync' component

[zinc robin]

oh sweet

i add it to all my object that need to me picked up?

[fallen chasm]

anything you want to be visibly synced, yep

[zinc robin]

Thanks 😄

Also like is there a easy way to just make a quick toggle on and off, first time using udon and its not like before

[fallen chasm]

toggling objects? like a mirror toggle for example?

[zinc robin]

mhm

[fallen chasm]

an udon graph like that would let you make something into a 'toggle' button

[zinc robin]

ohh so its not as quick to make as before xD

[fallen chasm]

well... you could also use a UI and toggle button

it's pretty easy to just target a gameobject with those and 'setActive'

[zinc robin]

hmm prob gonna need to watch a quick vid

first time in udon so everything new

[fallen chasm]

Plenty of tutorials out there now

https://www.youtube.com/c/VowganVR/videos

Vowgan does really good ones^

[zinc robin]

sweet

thanks 😄

[zinc robin]

Ohh sorry xD 1 more quick thing

So i have some particles in my world

But in the mirror they dont show up

its just default particles
