Ultra delightfulness of nodes

[pallid mango]

Perfect

[zealous mason]

Also, here's my attempt at short vs long hold of input, if anyone else was interested

[grand temple]

for something like that, it's a lot simpler to just use Time.timeSinceLevelLoad. Messing with a datetime adds an extra cost which isn't a huge deal when it's small but it could add up.

[zealous mason]

level load? I'm just using it as a button really, want the button to do different things depending how long its held for

[grand temple]

Time.timeSinceLevelLoad is just a single float of how long you've been in the instance. It would be much simpler to compare that than a datetime because it contains many floats

[zealous mason]

oh i understand ya now

good to know

in like seconds?

[grand temple]

yes

[zealous mason]

nice

Udon Drives Our Nodes

[kind swallow]

You know, I'm wondering right is it possible to sync (even if its local) requests to join to trigger events.

[floral dove]

Do you mean requests to join the world?

[kind swallow]

Yesh.

I was thinking it'd be interesting for somehow a bagging sound for whenever joins kek

[floral dove]

You can use the OnPlayerJoin event to do something whenever a player actually joins, but we do not expose requests to the world.

[fading cipher]

Didn't someone just make a tutorial on join sounds?

Was it a U#-only tut from vowgan?

[cunning mist]

That was me, I did Graph and Sharp 👍
I can link it if you'd like

[fading cipher]

I already know of it but I bet @kind swallow would appreciate it!

I was thinking it'd be interesting for a "apartment" scene when whenever someone requests, you'd hear loud banging on the door. Similar to that old japanese parents outside the door room

[pallid mango]

It’s canon, now.

[MOVED]

actually ima move this to world-development, might fit better in general

[cunning mist]

Momo this is recursive this isn't allowed

[fiery yoke]

PHP wants to talk to you

[dawn forge]

Wait till someone forkbombs their own world and kill Udon.

[fading cipher]

Wait a darned second vowgan where did you get that background photo

That is the exact art style I want in my world (Genshin impact basically), but if that's something YOU made I need to have a word or a paragraph or an essay with you about your world design lol

[cunning mist]

It's actually an environment I made from a nature pack on the Unity asset store. It's for 2019 however, so there was a lot of manual back-porting that I had to do to make it work with 2018. It's absolutely gorgeous however.

Hey all, been having issues with Vive controls yet again and I would like to verify something: currently my "is vive user gripping" check checks to see if InputDrop is true (so they're pressing their grab button) and InputUse is false...

What actually is fired for Vive wands for InputUse?

I know that

https://i.imgur.com/9IQiyd3.png

But which trigger button...

[floral dove]

I believe that Vive wands fire both Use and Grab when using the trigger because the Grab buttons are so hard to press

[fading cipher]

I expect them to fire grab, but they fire use too? That might be part of the problem

Quick question on Vive stuff again...

https://i.imgur.com/I62GZvb.png

This log is spamming Keyboard and Mouse when I move/look around on Desktop mode, but when my Vive friend checks his logs the response is only ever 4 (When I'd expect Vive). Is there a way I can specifically say I want to check for the value equating 4 instead of just Vive, which I'm already doing?

Because further down the chain of methods I'm checking to see if userIsVive, debug something that should essentially be spamming the logs, but he's not getting that debug

So I feel like userIsVive is never being set, and my best guess would be that it's because it thinks that GetLastUsedInputMethod() != Vive, because it == 4, even though I do recall that is the index of the enum...

aha nope, it's the other thing

It has to be ViveAdvanced huh

https://i.imgur.com/RAaks2F.png

Is casting it into 4 legal? 🤔

if (InputManager.GetLastUsedInputMethod() == (VRCInputMethod)4)```

I'm not getting a compile error on that so I'll hope and pray

[floral dove]

yes, you can cast an int to an enum, and vice versa

[fading cipher]

beautiful, so here's hoping that works, thanks again momo

I know you had to help me resolve this last time too all those months ago 😛

[floral dove]

oh - but 4 is not a valid Enum value fro VRCInputMethod

[fading cipher]

Isn't 4 ViveAdvanced?

I mean if it's not, why is 4 just not available to check in the enum, and why does my LateUpdate check return 4 in the debug in the above picture for my vive using friend?

[floral dove]

Aha! I believe you've found a bug...
The actual VRCInputManager has an InputMethod enum which lists Vive as 4 and ViveAdvanced as 5.
VRCInputManager.LastInputMethod returns a value of type VRCInputManager.InputMethod.
However, Udon accesses a proxy class called InputManager, which has an enum that doesn't quite match up.

So you can instead cast the returned value to an int and compare ints.

if you receive either 4 or 5, then your user is on Vive or ViveAdvanced.

[fading cipher]

Ohhh so I want to do if ((int)InputManager.GetLastUsedInputMethod() == 4 || (int)InputManager.GetLastUsedInputMethod() == 5) for vive?

[floral dove]

yes, that looks right to me.

[fading cipher]

Great, I'll give that a shot and report back once we can test it (other dev setting up vive for this now lol)

[floral dove]

You can save on calls to the InputManager property this way if you like, I think it reads a little more cleanly as well:

int inputMethod = (int)InputManager.GetLastUsedInputMethod();
if(inputMethod == 4 || inputMethod == 5)...

[fading cipher]

oh good idea, thanks

Funny how I'm always finding bugs and funky behavior with my attempt to support vive in my world xD

Thanks again for all the troubleshooting help!

[fading cipher]

It worked, thanks momo!

Trying to add a small area in front of a microphone increase the users volume.

[grand temple]

Changing the voice settings of the local player doesn't do anything. You need to change the voice settings from another player's perspective, so don't gate it behind islocal

Also your script is crashing because you don't have anything plugged into the setvoicegain nodes

[alpine trellis]

I appreciate it. Some obvious stuff slips by me a lot of the time

[bleak echo]

Is it possible to receive an interact event from another object?

(that other object would be in a public variable)

[cunning mist]

Instead of calling Interact on a different object, call "SendCustomEvent" for your target udonbehaviour variable.

[bleak echo]

That pointed me in the right direction, thanks.

[fading cipher]

welcome to programming lol

[placid kelp]

Is setowner available only to the owner of the object?

[grand temple]

anybody can set owner to anybody else

if someone tries to take ownership, you can add OnOwnershippRequest and returning false will deny the transfer. The current owner will have the final authority on whether or not the transfer is allowed to go through

[placid kelp]

If not add, does ownership transfer immediately?

[grand temple]

even if you do add that, it always transfers immediately. If the owner denies it, then it will revert

[placid kelp]

is doesn't seem to work for object.this

[grand temple]

vrc pickup already transfers ownership, that's not necessary

[placid kelp]

An error was found. Thank you

[placid kelp]

maybe pickup does not transfer ownership

It works but doesn't work after remove SetOwner

[final thorn]

Udon# does not support Actions/events/delagates how should I subscribe and unsubscribe to events from other scripts?

[grand temple]

sendcustomevent takes a string, so you can just set up your own event queue with an array of strings

[sick tangle]

can someone show me how i can control a blend tree with a ui slider trying to change a value of materials on world im working on still very new to udon any help will be very appreciated

[cunning mist]

Have your slider call SendCustomEvent to your graph in the OnValueChanged, then have your custom event graph in your graph set the value of the animator float you're setting to be the slider's value.

[sick tangle]

like this

yea im doing something wrong

[scarlet lake]

Hello I need some information.
Do I need 3 Vr tracker or with 2 is enough?
(One for each foot)

[sick tangle]

wrong channel but you need 3

[grand temple]

you can use one for your hips, but there is no configuration for 2

[scarlet lake]

ah ok thanks

[scarlet lake]

what is the channel ?

[grand temple]

#full-body-tracking would be appropriate

[scarlet lake]

thanks !

[hushed gazelle]

Can anyone tell if I'm missing something to get this object to sync between all players properly? (Put it in Debug mode, just in case)

[grand temple]

debug mode just makes it harder to see what we're looking at

but I don't see why that wouldn't work. Does it?

[hushed gazelle]

It does not.

[grand temple]

are you instantiating it?

[hushed gazelle]

Nope, it's just sitting in the world ready for use.

[cunning mist]

Maybe there's some arguments between the Udon Behaviour and the Object sync? I don't think that's a thing, but try disabling position sync on the Udon Behaviour.

[lucid otter]

does anyone have a solution for spawning a new card (playing cards) when a card is picked up? but only have that event fire once per card per reset (hope that made any sense)

• working on my first world and ive not scripted anything in my life so this is wildly confusing 😩

[pallid mango]

Last I checked two you a hip and then both feet go to the bottom tracker for a mermaid type of situation

[grand temple]

that sounds weird. If it does work, it's certainly not a "supported" configuration

[crystal verge]

Is there a way to record/playback voice with Udon?

[fiery yoke]

No.

Well. Technically maybe possibly. But not supported.

[crystal verge]

Ok, what would the godawful sidechannel hack be? 🙂

[cunning mist]

You don't want that answer lol

[fiery yoke]

Actually no. You cant get the player audio at all I think. At least Im not aware of any methods that could achieve that.

[crystal verge]

Yeah I saw some simple reprocessing stuff in the player audio functions, but that's it.

[fiery yoke]

Meh actually it might be possible, but not in the way you want it :P

[grand temple]

the absolute most you could do is have a special avatar that made the visemes animate cubes at a specific location and then the world would detect that. Visemes have enough information to know generally what they were saying, but it's not even close to enough to actually reconstruct a sound file

[fiery yoke]

There is a hack with getting a second AudioListener into the scene, which you could then grab audio data from. If thats even exposed in Udon...

[crystal verge]

Yup, this would be for reprocessing the voice sample with different impulse responses for convolutional reverb, so visemes ain't gonna do it.

[cunning mist]

Just have a bot in the world that streams to a url and play that url back in world and read the audiospectrumdata off of that 👌

[obtuse agate]

i made a convolutional reverb world but it only takes input from video player

[void ridge]

there's a canny request for this, pls upvote

[dapper lion]

audio listeners and vrc are quite interesting. but im not sure what helpfulhelper is refering to

[fading cipher]

we want voice reverb!

[scarlet lake]

Does anyone know of a way to get Spotify to play in world on pc or quest or both?

Without being played through a players mic output that is.

[stark adder]

Not possible

[scarlet lake]

Well damn.

[sick tangle]

can some one guide me with what im doing wrong trying to animate a blend tree with a slider ive been trying to figure for a while now just not smart with this stuff at all

[slim hound]

You have your references mixed up

You have your slider assigned to be the animator reference and animator reference going into your get value from slider

[sick tangle]

so i would just need to flip the slider and animator around

[slim hound]

You could just click on the drop down on those variables and change them

[sick tangle]

yea so like this then

[slim hound]

Yeah

[sick tangle]

ok ill give it a go and see if it works

do i have to go into a actual test build to see it work or can i just test it play mode

[slim hound]

It is possible but can be tedious without a tool for it

Assuming you don't have this you will want it for in editor testing https://github.com/CyanLaser/CyanEmu/releases/tag/v0.3.8

[sick tangle]

ill give it a go

ok its still not working going to check and upload a version to vrc just in-case

[slim hound]

@sick tangle What are you trying to do though?

[sick tangle]

trying change the hue of a material with a slider

[slim hound]

And the hue is controlled by an animation?

[sick tangle]

yea its using a blend tree

its the only way i could think of doing it

[slim hound]

You can directly set the playback time of an animation with animator.play

which would probably be easier

Make one of these nodes and in the dropdown set it to string int float like this

[sick tangle]

so i would make one animation for it and then put the slider on normalized time and the animator on the instance

[slim hound]

Yeah

[sick tangle]

do i need to do anything in the animator or can it just be a basic animation

[slim hound]

Basic animation

[sick tangle]

sweet ill give it a go thanks for the help

[slim hound]

The state name input is just the name of the animation in the animator and you will also want to set its speed to 0 so it doesn't change on its own

[sick tangle]

ok

ok i got this now

[slim hound]

Does that work though? last time I tried Set playbackTime it didn't

[sick tangle]

crap my bad this XD

omg it works thank you so much

[fathom oak]

Hmm. Sooo, I'm using Merlin's UdonSharpVideo player.
I want it so that there's multiple screen (emission renders) by cloning the screen, which does work, but has no audio, I cloned the AVPro video speakers L and R, but there's no sound coming from those.
I have no idea what I'm doing wrong

[raven latch]

I’m having a problem I on Pc I can't hear other people in the game😭

neeed help. i was hoping anybody here knows this simple function.
first room player talks -> transfers voice to another room.

[tawny portal]

Hi ! So I'm making baby steps in udon, and my scene won't build - I get this :

ArgumentException: The Assembly UnityEditor is referenced by VRCCore-Editor ('Assets/VRCSDK/Plugins/VRCCore-Editor.dll'). But the dll is not allowed to be included or could not be found.

Would anyone have an idea of what can cause this ?

Not a single issue so far! This has literally never happened before when creating such a complex system.

Once released any player can be added to countless overrides, each can have a different private channel or priority.

[small beacon]

Can i make a animation toggle with the same sort of setup as a mirror toggle

[torn pendant]

this one is complex i need just a simple way to pick up the voice of players and transmit it on another room

like if there is a camera in that room it will be able to pick the voice of players

[hard wraith]

its done basically how that video shows, setting the players voice distance inside a zone to a value for the players in the other room

cause u cant make someones audio emit from somewhere else only increase the distance it is heard from

[potent lark]

This just an Udon Script Issue?

[tardy mountain]

Hi Is there a tutorial or a something I can look up about using the simple pen system prefab that comes with SDK3? I am looking to have a button that clears the pens.

[dapper lion]

no but there are like... 2 pen prefabs on the market that might fill that need

depends if its needed or not

[tardy mountain]

I know there are prefabs. but I would like to use the VRchat simple pens that and have one button that clears or resets the pens.

[crystal osprey]

is it possible to make a avatar quality block using the player api to stop very poor avatars from entering the world

[cunning mist]

Udon does not have access to the player's avatar information, so no.

[crystal osprey]

well it was just a idea thanks for the answer

[fiery yoke]

You can check if someones FPS is low :^)

But obviously thats not what you want

[cunning mist]

No, that's not how that works

[fiery yoke]

Yeah no in general you shouldnt block entry from a world in Udon automatically from anyone, for any reason.

[crystal osprey]

club worlds have alot of time problem with people not following the avatar quality req

[fiery yoke]

Well then you need to have better event organization regulations.

[cunning mist]

This isn't productive THH

[fiery yoke]

But its the sad truth. Either you strictly enforce good avatar requirements. Or you need to tell everyone to use their safety settings and automatically hide poor or very poor avatars.

I mean thats exactly what the performance blocking system was introduced for

why not just use that? is it not sufficient?

[pearl ledge]

is there a way to attach components to the player camera?

[pastel yew]

Super quick Q; Trying to add a 2D/3D positional toggle for a streaming player in a world... people like 2D audio enough to have requested it. 🤷

Tried just toggling between two different audio sources, but that breaks the audio. Is there a proper way of doing it?

[grand temple]

spatial blend is a property on the audiosource

setting it to 0 is 2D, 1 is 3D

[cunning mist]

If what you're after is attaching objects to it, just have an object that constantly sets it's position to the local player's TrackingData.Head

[dapper finch]

So I'm making a map with lots of different udon games and I was able to get a hold of a couple of them but it seems that I don't know if I have the right scripts for them because each time I try to import different games like drinking roulette or never have I ever I get error messages and I do not know if I'm missing any script that is necessary same goes for the pool table I'm working with for some reason each time I import it it says I'm missing or having error with one of the pushable buttons... So if anyone can help me or link me to an area that would help me figure out where I need to do or do I need to go would be appreciated

[dapper lion]

if i recall. those pens make a parent and a child per line, and you can probably delete all the children in a discovered array. but im not 100%

ive never acc seen anyone want to use those pens before

[pastel yew]

Yeah, it's the Udon side of that I'm having trouble with.
I know how to toggle a bool, but spatial blend is a float so can't just be flipped on-if-off, and off-if-on. 🤔

[grand temple]

just set it to 0 or 1

[pastel yew]

Mm, but then would need two buttons - one for 1, and another for 0. Ideally I'd like a single toggle button.

[grand temple]

so if it's 1, set it to 0. If it's 0, set it to 1

you can do that with a float equals and a branch

[pastel yew]

Would you have an example? I'm still trying to wrap my brain around Udon~ ¦O

So far I have the individual buttons kinda working with this:

[grand temple]

you have nodes for set spatial blend, add another node for get spatial blend

[pastel yew]

The 2D button still has the positional thing going on, I haven't worked out how to flatten that out yet.

[grand temple]

plug the spatial blend into a float equals node, which will give you a bool true/false

bools can be plugged into a branch, which allows you to redirect the flow (white lines) one way or another

[pastel yew]

Ahhh, gotcha~ I'll have a play with that tomorrow, it's past 3am already and my brain is cooked. ¦3

Thanks!

[torn pendant]

i got a question.

can you use set voice distance near and set voice distance far?

im trying to make player voice be heard for the entire map.
distance near has louder voice while distance far is low voice.

[grand temple]

Near defines the start of the curve and far defines the end of the curve. You can use both together to make the voice heard equally across the map

Just set both to 10k

And then set gain to 0 because that will make it very loud. Default gain is 15

[torn pendant]

i think im doing it wrong im trying to figure the proper noodle setting

[pallid remnant]

how does one use VRCtriggerRelay?

[finite moss]

Hello everyone, I am trying to spawn a particle system (jumping particle) to player when it jumps. VRCInstantiate is the way to spawn it but I am not sure how to get the position when player jumps.

[fickle stirrup]

use InputJump override to check if player jump https://docs.vrchat.com/docs/input-events
it takes an argument value which you need to check if it's true if you want to spawn on press, or false if to spawn on release
and inside of it use Networking.LocalPlayer.GetPosition() to get player's position and apply to instantiated object's transform.position=
or Networking.LocalPlayer.GetBonePosition(... which takes an argument of HumanBodyBones.Neck / LeftHand / etc https://docs.unity3d.com/ScriptReference/HumanBodyBones.html

[finite moss]

Thank you so much! This solved all my problems.

[prime fossil]

how do i make vrc pickups respawn in sdk3?

[fickle stirrup]

maybe. save their position at start, when you need call .transform.position= to the saved one, might also need to call pickup.Drop and not sure but maybe ownership transfer (don't know if position change will be synced for everyone without owner'ing this pickup, you can test)

[finite cove]

!HELP! My mp I am building has a Memory Leak. How do I find the source of this problem. My map is literally just PNGS with one reflection prob and a TV that reflects the light on the walls of the room

Could it be the amount of times the reflection is updating?

[sharp briar]

i'm getting these errors when i try and upload, any clue how to fix?

[dapper lion]

i mean. you should probs use a baked reflection probe. but the likely hood youre actually expeierencing a memory leak is super duper low

[dapper lion]

have you tried compiling all udonsharp scripts?

[sharp briar]

just tried and i got a new error, i think i might just need update some stuff i guess?

[dawn forge]

Looks like you're trying to set a jump impulse. You're using Visual Studio? Udon is having trouble extern to jump impulse for the player movement settings

[sharp briar]

is extern just an upload thing? i did a test build and it ran fine

[dapper lion]

i mean, if its a non-failed compiler issue. then is the script failing then?

reading closer: i dont exactly see is issue unless it is visually happening in game

[sharp briar]

i just cant upload

[dapper lion]

hmm. is that script actually being used?

it might also be needing updating if the prefab is meant for something like the UNU sdk

[sharp briar]

yeah i figure updating things will fix it at this point

[rough beacon]

i have this weird mirror bug. mirror seem to by 90o off and the obj in right spot o.o

[hushed gazelle]

@prime fossil Teleport it to somewhere under your map and let the built-in respawn code handle it.

[rough beacon]

can VRC_Mirror be broken?

[native estuary]

Sure, if you use a mesh not properly set up for it

[solid sluice]

it has to be with a project from view? the UV map i mean

[rough beacon]

i think it maybe a error in c sharp

[native estuary]

The UV doesn't really matter, it's more about having the normals facing the right way on the objects local space. Like for example default quad would have them right but default plane would not.

[chilly aspen]

I'd like to use a font in a TMP Textbox. Using <font="Times New Roman SDF">Hello World!</font> works correctly in the editor. However, when I build and test the world, the rich text does not appear. The only font that works correctly with rich text is LiberationSans SDF.

Is there a specific folder I need to place the Times New Roman SDF font package? Unsure why one font works but not the other.

[stark adder]

I know someone had this problem before it was because the font it not being included in the package.. Not sure how they solved it

Wait @native estuary did I miss you being active chat mod ? Or are you newly ? 🤔

is there a way to interact with a gameobjects UIText directly using U# not graph?

[pastel yew]

Hey! Does anyone know how I would access this spatialization checkbox on the VRC Spatial Audio component in Udon graph?

I thought it was this one but apparently not. 🤔

At least, it doesn't seem to have any effect~

Basically trying to create a toggle for the directional part of an audio source.

(the 2D-3D spatial blend slider only seems to change the volume at distance element, and not the directional/direct-to-the-earballs balls)

[prime fossil]

Those that only interact with stuff like the api and some that affect the cache or config for example

But nothing that directly mods the game

External tools likr steam ovr stuff or windows tools like auto starting vrc are fine too

[pure parrot]

hi guys , i just wanted to ask if i should learn Udon or C# of unity to start coding , i am about to make a card game but i have no idea on what to take to start

[coarse parrot]

Yes you should. And also general idea about programming too.

[pastel yew]

Udon for VRChat, C# for a Unity game.

VRChat doesn't allow most C# scripts to be used.

[pure parrot]

oh

so i don't rlly have the choice then

thx for the replies

[fading cipher]

@pure parrot if you plan on learning to program in the future for your career, there’s an extension for VRChat that allows you to write C# to make Udon programs, but it’s probably not worth the effort of learning to write in C# if it’s only for VRChat

As an aspiring Unity game dev I wouldn’t be caught dead writing in Udon Graph 🥴

[pure parrot]

is coding in C# that painful ?

[grand temple]

It's not that it's painful, it's just that udon can only utilize a portion of what c# has to offer. If you learn c# in a normal situation you'll deal with inheritance, lists, LINQ, and all kinds of other useful things. But then udon can't make use of any of that, so if your goal is to learn c# to get better at udon then that would be a waste of time

If you want to make something in udon, just start learning and don't overthink it. The graph is a good place to start and you can consider other options later

[void ridge]

I continue to disagree with this. Udon Graph has been a very nice stepping stone for me to learn some important fundamentals of programming.

It allows you to put syntax on hold while you learn some of the other hard stuff that's otherwise tough for new programmers to get their head around.

I've yet to see any real argument about why node-based programming isn't a good place to start learning. And all the objections I see are always from people who are already experienced comfortable and familiar with text-based programming.

[fading cipher]

Maybe I'm biased since I'm not new :v

yeah then you know it better than I do

[wanton oxide]

idk man i would say U# is miles ahead of udon graph just because writing code and working with it is so much more efficient than working with the graph

[void ridge]

I'm currently transitioning from Graphs to U# and finding it delightful

[wanton oxide]

graph is nice to learn some of the simple concepts i guess but if you take yourself somewhat seriously you should transition at some point

yes

[void ridge]

I haven't said and won't say that U# isn't more efficient to use. I'm sure it is more efficient. But Graphs are easier to learn.

[grand temple]

Also graphs have improved a lot in the last few months. If you tried it a year ago and were stuck on the bugs and freezes, then you would probably be surprised at how usable it is today

[wanton oxide]

i would disagree with even that probably

but i've been programming for years and years now

[wanton oxide]

oh yeah they have, i still occasionally try to see whats new and stuff

[void ridge]

Yeah, that's also true. Even in my short-ish time using Graphs I've seen it improve in important ways. It's ultimately pretty usable, with lots of room for improvement. I used Graphs exclusively to program most of a legit VR theater production. It was often a bumpy ride, I didn't do as good a job as maybe I should have, and if I'd known U# I probably would have used it instead. But the fact is, it got done using Graphs.

[wanton oxide]

and compared to when i first used it around march of 2020 its a massive improvement

[wanton oxide]

the fact that its possible doesn't surprise me, everything you can do with U# can be done with graph

its just harder to do and especially harder to maintain :P

[rich patio]

I'm a U# user. There is absolutely nothing wrong with using graphs. Programming isn't about code, its about problem solving. the problem solving aspect is identical on both U# and Graph. They are pretty much identical.

[void ridge]

Harder yes. Point is, not too much harder.

[wanton oxide]

well thats where i disagree, idk when i use graph it takes at least 5 minutes to write something that would maybe take 20 seconds in U#

[void ridge]

git gud 😛

[rich patio]

I never used Graph at all to see how good it is.

[wanton oxide]

try writing something simple in it

just to see how it works

you'll see what i mean

if you're used to writing code, its a pain lmao

[grand temple]

Nobody is disagreeing that in your situation it is easier to use U# because you already had coding experience. Graphs are easier to learn for people who don't have coding experience

And yes, U# has a larger ceiling for expanding into massive projects but when you're just learning you won't have a large project anyway

[fiery yoke]

Also nevermind the still existing graph compilation bugs and inaccuracies and in general weird behaviour

[dapper lion]

graph isnt that bad

[fiery yoke]

Not sure if it is actually still in the graph, but try doing a "Conditional And" where the first bool is evaluated from "Utilities.IsValid(gameObject)" and the second bool is evaluated from "gameObject.name == "Test" ". This will fail because of how Udon works. It takes the "Conditional And" literally as one instruction and inputs the two bools, which have to be evaluated beforehand. And when evaluating the second one, it will fail if the first one is invalid. So yeah Udon is pretty stupid in this specific situation. Which is why UdonSharp for example doesnt compile it like this, but instead does two boolean checks afaik.

[simple shell]

Here's a question... is there are way to pipe text into a world? Like a Twitch chat IRC feed into a world. I'm doing a thing and would like to do as much as i can "in world" as possible.

[fiery yoke]

Only feasible way to do that would be Video Players. But if you mean text as in "string data", then no.

[sharp briar]

So I posted last night about some errors, I managed to clear most of them up but I'm still getting this error keeping me from uploading.

[fiery yoke]

This is not Udon related, but make sure that you have at least one object assigned as your spawn object in the Scene Descriptor Component

[sharp briar]

I'm posting here cause it is an udon world and i wasn't sure if there may be an issue, that being said my last picture did have some udon errors so I figured I'd follow up here

[pastel yew]

It's referencing VRCSDK2... not Udon.
If I had to guess, you've installed SDK3 on top of SDK2 and it's left over some old SDK 2 junk.

[fiery yoke]

Ahh good catch.

[sharp briar]

any way i can clear that up?

i did a test build using udon stuff and it was running fine on the test build

so im not sure how that happened

[grand temple]

close unity

navigate to the project and delete the VRCSDK and Udon folders

open the project

reimport vrcsdk3 world

go to file > build settings > player settings

make sure that "scripting define symbols" does not contain anything related to SDK2

[pastel yew]

It may work in test, but the script it's having issues with the RuntimeWorldCreation one... as the leftover SDK2 doesn't have all the correct things to run and create the world anymore, it's failing.

And the site does say this:

So... probably best to start again. Objects you've had in your SDK2 world will have scripts that reference SDK2 stuff too... so all of those would fail.

[ashen verge]

Alright so i've got a question. I've got a world with background audio and 88 other sources which i'm able to fire play events rapidly on. The moment i run my hands over them all the bg music will cut for a second then continue, i looked into this and it appeared to be due to the unity engines project settings for audio real voice which is defaulted to a low number but i'm pretty sure it will only affect my unity not vrchat bc vrc has the hard limit of somewhere around 32ish at once (from what i can guess based off experiences). Is there not a way to get past this? I've witnessed this exact same problem in midi keyboard world where i would play fast and the audio would just die for a while and come back catching up with previous audio clips.

[grand temple]

well, that's only if you are actually migrating from sdk2 to sdk3. If you just accidentally imported sdk2 into an sdk3 project, all you have to do is fix up the scripting define symbols

[sharp briar]

i dont have anything in the world with scripts referencing sdk2 theyre all udon behaviours

[pastel yew]

I mean, if its failing on an SDK2 thing... I'm guessing it WAS an SDK2 world, which has had SDK3 dumped on top... as SDK3 stuff is world. There is just SDK2 stuff left behind.

And the VRC site says you can't upgrade SDK2 to SDK3 without starting the project from fresh.

[grand temple]

but that's not their problem

it wasn't an sdk2 project, it just had sdk2 imported by accident at some point

[pastel yew]

Courtesy says it's an Udon world. So why then would it be failing on an SDK2 script?

[grand temple]

.....because it had sdk2 imported by accident at some point

and I am telling you

the way to fix that

is to remove sdk2 from scripting define symbols

[pastel yew]

Udon is working... so those are the latest files. SDK2 is failing, because SDK3 has over-written with files of the same names.

But yeah... eitherway, whichever was imported on top... you can't do that, hence the error.

It's a moot point... but that'd be the problem here. Mushed-up SDK.

[grand temple]

yes, and that's why I'm saying they need to wipe everything related to vrcsdk and import it fresh. Please follow the steps I posted above

[pastel yew]

Agree - try clearing the SDK stuff out completely as Phase said. But if it WAS originally and SDK2 world, you'll also need to look out for objects with SDK2-related components.

[grand temple]

they have said multiple times it was not an SDK2 world 🤦

[sharp briar]

just for the record, ive never made an sdk2 world in my life, i dont know how this happened

when i joined vrchat i figured itd be a waste to put any effort into sdk2 cause udon was the future

[pastel yew]

Aight, just trying to help here~

[sharp briar]

so i did what phasedragon said and a lot of things are not really functioning so im messing with stuff

the sdk was broken, prefabs were not assigning things

ive reimported some things and things are smoothing out

[grand temple]

the sdk will add everything it needs to the scripting define symbols so it might be best to just wipe it entirely before reimporting it

[sharp briar]

we're good

what you said worked, i just had to reimport udon sharp too

[grand temple]

cool!

[sharp briar]

nooooo clue how that happened

and i have seen "sdk2" appear on the screen at some point in my other worlds that uploaded just fine

so i dont know what even happened here

[grand temple]

eh, I've imported sdk2 by accident as well. They're on the same download page, it happens

[neon rain]

Anyone used ToggUltima before? Whenever I import it I get a ton of U# compile errors and Unity throws a fit and won't load the VRCSDK

https://cdn.discordapp.com/attachments/834251210143301646/861694966220849152/unknown.png

^ these are the errors

[dapper lion]

what is it supposed to do? are you using an older sdk?

[neon rain]

It's a set of scripts to toggle multiple objects at once. Using 3.0 version 2021.06.03.14.57

[dapper lion]

hmm weird. any other errors?

are you using the latest udonsharp?

[neon rain]

U# was outdated. Thanks!

[lone shoal]

can someone help?

[autumn cargo]

your pipeline manager is with an id that does not correspond with your account

pipeline manager is in the vrcworld prefab

I've been searching but can't seem to find anything on how to get player camera width and height

any ideas?

i do know how to get its pos and rot but not get the screeen's width and height

[pearl ledge]

what's the commonly accepted solution for attaching unity UI prefabs to a player camera? can it be done?

can I just make a Unity canvas and use that, or will that mess things up?

[slim hound]

@pearl ledge An interactive one or just for visuals?

[pearl ledge]

not interactive by the player, I just want a basic health bar

[slim hound]

You can just use GetTrackingData > Head

[pearl ledge]

I'm just not sure how to attach unity UI stuff to whatever prefab I attach to the player's head

I've successfully gotten a cube to follow and rotate with the player's head, I'm just not sure where to go from there with the UI stuff

[slim hound]

UI is just an object that you would put on that object that tracks the players head

[pearl ledge]

I tried creating a UI object as a child of the object, but it made a canvas when I did that

[slim hound]

There are free UI prefabs on the asset store that you could get as a reference

[pearl ledge]

I'll look into that, thanks

[pearl ledge]

is there a way to detect key presses on the keyboard with Udon?

[slim hound]

Input GetKeyDown

[fading cipher]

(Obj sequencing) That's interesting. Just how much more optimized would, say, 100 sequenced models be compared to 100 animated models?

[pallid mango]

You are only seeing one object at a time, so it’s still just 1 mesh render vs 1 skinned mesh render.

Udon code itself to do the swapping is negligible

[autumn birch]

Anyone ever convert C# stuff to udonsharp for use in VRchat? Like a flock of birds script?

[fiery yoke]

#udon-showoff message
Yes. That has been done since Udon existed. Even before UdonSharp existed I think.

[dapper finch]

Is anyone have unity udon games like drinking roulette the pool table never have I ever and if anyone can send me the unity packages he'll make it easier so I don't have to worry about errors or not knowing what scripts I'm missing in my project

[scarlet lake]

i need help

pls

with a problem with a problem with teleporting

[slim hound]

@scarlet lake What issue are you having?

[scarlet lake]

i have this problem where i have toggle button when u click it teleports to random spot but i want to where i want to but everytime i change it spawns somewhere else

[cold raft]

Oke this going to be an odd question. But iv changed the udon behaviours for the vending machine prefab to use an object pool and manuelly sync an int per can for its material when it spawns. Now this sometimes crashes some players, like really crash thier vrchat. And it makes me wonder, obviously I did something wrong, but should the udon behaviour not just fail and not proceed to crash the player?

[slim hound]

@cold raft Are you using any custom events in your setup?

[cold raft]

no, unless udon sharp compiles things as events, it's an udon behaviour that calls a method on an other udon behaviour, basicly when someone presses the vending machine button, it will request the actor to become the owner of the object pool, then spawn a can. Then also set the can's owner to that same player and update the materialid variable, and on deserialisation on other clients it will update the material based on the materialid

[slim hound]

Calls a method?

From your description it sounds like you are using a custom event

Which is a possible cause of crashing if you create a feedback loop

[cold raft]

Intresting, can you define the feedback loop?

[slim hound]

If you activate a function and within that function it manages to activate itself again

One thing you could start with is add logging functions to parts of your setup and try reproduce the crash yourself and then check the logs to see where it failed

[cold raft]

Yes I was thinking something like that, not sure how I could view logs when it crashes an I am sure I cant write logs to disk, also unfortunately it never crashed for me yet only for others

[slim hound]

The VRChat logs are viewable even if the game crashes

[cold raft]

Any idea where to find them? up until now iv been using the ingame console

[slim hound]

!outputlog

[fleet bramble]

You can find your output log at C:\Users\%Username%\AppData\LocalLow\VRChat\vrchat named output_log.txt

[cold raft]

also FYI this is what i meant with calling methods on other behaviours i did it like this, i am not sure if udon# compiles this to events

    public GameObject VendingMachine;

    public override void Interact()
    {
        var vendingMachine = VendingMachine.GetComponent<SynchedVendingMachine>();
        var material = GetComponent<Renderer>().material;

        vendingMachine.SpawnCanWithMaterial(material);
    }

[slim hound]

Ah right

So that udon behavior is set to do something on another udon behavior?

[cold raft]

the interact is on 6 different buttons, and it uses the material on the button for the can
the SynchedVendingMachine behaviour is on the machine itzelf, it handles the spawning of new cans and also maintains an syncronized int[] of what material id should be on which can, i can dm you the code if your intrested but with 140 lines its a but to much to post here in chat

[slim hound]

Sure I'll take a look

[scarlet lake]

Did you see my question?

[slim hound]

Oh yeah sorry.

If you could show your setup that would help

[scarlet lake]

Do you mean like the code for it

For udon

[slim hound]

Well yeah any part of your setup could help

[slim hound]

And when you click the button to teleport it puts you at the wrong location?

[scarlet lake]

Yes

[slim hound]

You would want to look at the game object that you have set as your teleport location

How do you have that game object setup

[scarlet lake]

I have it up in the air a little so people can just drop and a little not that high and on everything right because I have another button with the same udon thing well almost but that one works just fine which I don’t get

[slim hound]

Does your other button target a different teleport location?

[scarlet lake]

Yes but there not connected

To the one that’s having problems

[slim hound]

The one that isn't working properly is likely being moved

If you drag the non working teleport location gameobject onto the one that does work I would guess that should fix it assuming its an issue with a parent object moving

Or you could have an udon behavior or rigidbody on your target location game object that is moving also which you would want to remove if you do

[scarlet lake]

I will give it a try

[mighty fjord]

Hey @scarlet lake, could the issue be that you're getting the localPosition/Rotation from the target transform when you actually want to get the world space position/rotation?

[scarlet lake]

I will try to ur idea and his idea maybe trying both out

Because it’s not local

[slim hound]

If you aren't using local position intentionally then that will be the cause

[scarlet lake]

Well I did before

And it did the same damn thing

[mighty fjord]

Local positions are relative, so if the transform's parent you're targeting is not at the world origin then you'd have to do some extra stuff to translate the coordinates to world space again

[scarlet lake]

Well I don’t know how to do that lol 😂

[mighty fjord]

And that's why we can get the world position directly instead of doing localPosition, the node should just be called Position instead of localPosition

[autumn cargo]

hey guys

i still got a problem

so my tp works with some avatar and some doesnt work

what is causing it to not recognize the collider?

[scarlet lake]

fixed

[mighty fjord]

Did it work now? What was the patch? ^^

[scarlet lake]

moving it a little

when i tried that yesterday

[autumn cargo]

wth, my ontriggerenter only works with specific avatars

[dapper lion]

thats weird

[pallid mango]

Just to be sure, you have OnPlayerTriggerEnter, right?

[fickle stirrup]

if not, you should make an extra trigger which will follow the local player, custom Layer for that trigger and for your onentertrigger's one, to make them collide only with each other

[autumn cargo]

the thing i'm doing is

when the player touch my collider i call ontriggerenter

for the ontriggerenter to only work with the player i was using the layer player

[grand temple]

ontriggerenter happens from avatar stations, but that's not what you want

you should use onplayertriggerenter

then you can also check if the player that touched is local

[autumn cargo]

i see

then why the ontriggerenter worked?

dynamic collider?

[grand temple]

because it hit an avatar station

[autumn cargo]

whaT?

[grand temple]

or a collider, sure. Whatever was on the avatar

[autumn cargo]

aah

i'll change here thanks

[opaque loom]

Hi so I'm trying to change the bloom of some of my assets using a script, but I'm getting this error:

Assets\Scrips\GlowSlider.cs(12,11): System.NotSupportedException: Udon does not support variables of type 'Bloom' yet

My code is:

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;
using UnityEngine.UI;
using UnityEngine.Rendering.PostProcessing;

public class GlowSlider : UdonSharpBehaviour
{
    private Slider _slide;
    public Bloom bloomTarget;

    void Start()
    {
        _slide = transform.GetComponent<Slider>();
    }

    public void SlideUpdate()
    {
        bloomTarget.intensity.value = _slide.value;

    }

}

This code is in a slider and the bloom is in another object

[winter parrot]

hey im getting a weird glitch with udon audio link, where only the bass will work but nothing else (treble and stuff ), ive tried different songs, audio sources, everything. and it still doesnt work :c

[flint urchin]

PostProcessing isn't supported in Udon (yet), so you need to use a animation proxy

[broken bear]

Can you affect the speed of an animation in runtime? I want to trigger an animation by a trigger area that runs say a 5 second animation, but if a player leaves the area before the animation finishes, I want the animation to immediately reverse from its current keyframe.

Conceptually it would be making the animation state machine run the animation at speed -1 but not sure if that’s available from udon. I can pause the animation by flipping the animator to off but I can’t get it to run a “reverse” animation from the given keyframe.

I guess I could measure time from entry and expected completion, calculate it as a percentage into a float and feed that as an animation parameter for a “normalize time” and on exit of the area do delayed events to reduce the parameter till it’s back at 0, but that is a bit beyond me

[opaque loom]

For some reason something in my world doesn't work when I use it in VRchat but it does work when I run the unity game, does anyone know why?
My code is:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Rendering.PostProcessing;


public class SetBLM : MonoBehaviour
{
    public PostProcessVolume volume;
    public float BloomIntensityValue;
    public Slider sliderFD;
    public float ValueOfSlider = 1f;

    void Update()
    {
        ValueOfSlider = sliderFD.value;
        ChangeBloomIntensitySettings();
        BloomIntensityValue = sliderFD.value;
    }
    public void ChangeBloomIntensitySettings()
    {
        volume = gameObject.GetComponent<PostProcessVolume>();
        Bloom bloom;
        volume.profile.TryGetSettings(out bloom);
        bloom.intensity.value = BloomIntensityValue;
    }
}

and

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

public class GlowSlider : UdonSharpBehaviour
{
    public Slider _slide;


    void Start()
    {
        _slide = transform.GetComponent<Slider>();


    }

    public void SlideUpdate()
    {


    }

}

[flint urchin]

Again, PostProcessing doesn't work with Udon graph/code at the moment.

You need an animator that does the post processing values and control the animator via udon

[solid sapphire]

Does anyone know where to get a decent Udon Flying prefab to fly like a bird?

[void ridge]

If you're a bird, I'm a bird

Thank you homie

[open estuary]

Hello , I'm struggling against udon graphs to make my animations toggles synced , even with late joiner, even with "Synced Toggles & Animations and Event Buttons" Tutorials from Vowgan but it's always getting unsynced or reversed....

Can someone have some times to help me ? :x

[fallen prawn]

That may be the OLD tutorial. Which come Before UnU (Udon networking Update.), Vowgan also mention that.

The concerning issue should be

• Do you test properly?
• How your sync variable type is, continuous or manual. You may read about this on docs.
  -> If manual, did you RequestSerialization() properly?
• Do you have OnOwnerTransfer() return value properly? (Yes, you must include this to transfer the owner properly.)
• Does it bug?

If you don't mind ,you may ask more about this in #udon-networking.

[open estuary]

Hmm actualy i've found a solution after many tries, not the best and i think could be more optimised i think.

For info it's continuous and no i don't do "OnOwnerTransfer"

[fiery yoke]

Whats your goal?

[slim hound]

If you're using normalized time to "reverse" an animation you could likely simplify the setup by also using normalized time to play the animation forwards and then you wouldn't have to measure anything as you would just increase float value when inside the area and decrease it when outside.

[edgy ingot]

im a little stumped, im making a basic mirror toggle system and the mirror can turn ON but not off

[fading cipher]

Probably a dumb question, but would the VRCMirror object break if you turned its box collider into a trigger?

[edgy ingot]

probably not

just know that there needs to be an active collider to turn it on

[fading cipher]

I mean, is it there for some raycast stuff done by the player, or is it there so you collide with it when walking? 🤔

[fiery yoke]

Im getting mixed signals from that message

[fading cipher]

I'm not toggling it

[fiery yoke]

latter. The mirrors collider is just a normal collider. You could even remove it.

[fading cipher]

awesome ok

[edgy ingot]

im not tryn to sound sarcastic, sorry if i did lol

[fiery yoke]

No its just your Username :^)

[edgy ingot]

oH

hehe

[edgy ingot]

i think it has to do with the fact i did i - 1, and maybe something had an error

[pallid mango]

No. It doesn’t even need a collider. Remove it and you’ll just be walk through it

[fading cipher]

I do need its collider, just wanted to be sure I could modify the one already on it 😛

[fiery yoke]

Yes. If you start at 0 and you do i - 1 then thats -1 and you cant index an array at -1.

[pallid mango]

It’s not used in anything to do with it being a mirror if that’s what you’re asking

It’s exclusively for collision and if you don’t need collision or want to use it for something else go for it

[fading cipher]

My world technically has no limit to the number of mirrors allowed in it, so I'm trying to write a mirror limiter script so only the nearest one is enabled, wanted to know if I could mess with the collider already on it for something like that but I just realized I won't be able to anyway

[edgy ingot]

ok awesome, that was exactly it

it hit me as i was looking at it just now and i was like
"huh... oh"

[fading cipher]

Actually on that note

If I have a list of objects in an array, and I am checking their distance from the player every few seconds or something

Am I able to check the distance of an object from the player if that object is disabled?

[pallid mango]

Better to use an object pool but, yes.

[fading cipher]

No object pools here

All of our code is custom code, objects are instantiated

[pallid mango]

Yes you can get any info you want from disabled objects

[fiery yoke]

Disabling an object in Unity simply disables all components. And disabling a component, simply removes it from Unitys core game loop. So it wont receive events like Start, Update, LateUpdate etc. Thats all there is to it.

[fading cipher]

woot, that's good

oh shit

I could disable the mirror component and leave the object

bruh

never even crossed my mind

[pallid mango]

Wait what does disabling the mirror script even do in game

[fading cipher]

I would presume it makes it stop being a mirror...

[fiery yoke]

Yeah you dont want that

[fading cipher]

rip, worth a shot lol

[pallid mango]

You would want to disable the mesh render

[fiery yoke]

You would also have to disable the Mesh Renderer

Damn you :P

[fading cipher]

Then let me continue this for grins

[fiery yoke]

Its better to just disable the entire GameObject

[fading cipher]

If you disable a mesh renderer on a mirror object does it still have some resource drain

[pallid mango]

Yeah please report back in what the heck disabling the script does because I honestly have no idea what that will even do

[fiery yoke]

It will probably either cause the texture to freeze, or go white.

[pallid mango]

I’m predicting something cool like objects in the mirror stop updating, but yeah probably something less cool

[fading cipher]

looks like it blackens

https://i.imgur.com/I7DTgEi.png

[pallid mango]

Well I can’t say it doesn’t make sense

[fiery yoke]

Thats in the editor

behaviour could be different in client

[fading cipher]

Happens in game view too but yeah you're right, let me toggle it in the prefab and build & test

https://i.imgur.com/wf2Sk5X.png

yep, white in-game

I think for now I will do just a mesh renderer toggle and in the future I can change it if questers still report lag from mirrors

That way I can keep it on the VRCmirror instead of making a new game object

Is there any real benefit to executing a delayed event something 40 frames apart instead of 20 frames or something if you're just trying to delay some distance checks so they're not running every frame?

[edgy ingot]

does anyone know the method name/call for play one shot in U#?

[grand temple]

it's the same as in normal unity, just audiosource.playoneshot

[edgy ingot]

tyty

[atomic sinew]

Is there a way to make something auto face the player camera in udonsharp?

[fiery yoke]

Yes thats possible. Albeit not as simple as it may seem.

[atomic sinew]

I'll try doing it the normal unity way, but I think vrchat dislikes anything using the camera

[fiery yoke]

You first need to get the local player api (Networking.get_LocalPlayer). Then you need to get the tracking data every frame in Update (PlayerAPI.GetTrackingData) for the Head. Then you have multiple options, but the easiest way is to create a GameObject where you set the position of its transform to the position of the tracking data you can get with TrackingData.get_Position and then finally you can use a LookAt Constraint with that GameObject.

[fiery yoke]

VRChat creates its own camera. The main camera is disabled in the client.

[atomic sinew]

hmm I see. I was curious, I'm already using get tracking data

Do you know if it takes up any performance or a lot?

[fiery yoke]

Well define a lot :P

Its not noticeable by itself.

[atomic sinew]

FPS hitter :o.

[open estuary]

For Resume :

• multiple toggles buttons for turn ON/OFF each of them one Parameter in my Animator
• Having them syncronised with everyone in the world + late joiners
• Having a keypad for disables only the buttons (already working)

Im actually with the version which looks like working but idk if its the best to do cause I needed to "split" in 5 the udon graph cause it was too long and froze my unity

We can talk about it in the evening (im EU) in vocal and I can show you if you have some time 🙏

What’s udon

[dawn forge]

?whatisudon

[hidden marten]

[tropic atlas]

how do I make it so pickup doesnt fly towards the hand but just stay at it current position?

[slim hound]

Haven't tried it myself but you might be able to assign a game object to the exact grip in the pickup script and move the specified grip position to the users hand position on pickup

[frank lily]

Hi! I'm having a new issue in my world after updating the merlin video player and vrc billiards, for some reason the world master of the world will just have worse framerates

it seems to also transfer to the new room master when the current one leaves

between like 5 of my friends, they were reporting their individual framerates tanked hard when they were promoted to master

my world also has QVpen's newest version in it though it was not updated in the last change

vrcbilliards was updated from 1.1.3 to 1.1.7
merlins usharp video was updated from 0.3.0 to v1

nothing else in my world was changed from the last update aside from these 2 prefabs

[slim hound]

Tried it myself and the easiest way to get this behavior is to set the pickup orientation to grip and have nothing set as the target transform

[tropic atlas]

omg thank you, I was write the code against humanity

[narrow cloak]

How do i fix this mess?

[coarse parrot]

have you imported udonsharp package?

[narrow cloak]

lmao, nope. Im an idiot

[burnt moth]

how do you make something that enables and disables a mirror

[narrow cloak]

Any ideas why my teleporter isnt working

[coarse parrot]

You haven't assigned which event to call on SendCustomEvent

[narrow cloak]

isnt that what the public variables target box is for? if not I dunno how to add the event there lol

[coarse parrot]

You had this blank

The event name is the same name as you assign in CustomEvent node in another object

[narrow cloak]

Still not working
getting
Program asset 'Assets/Scenes/SampleScene_UdonProgramSources/Cylinder (14) Udon C# Program Asset.asset' is missing a source C# script
UnityEngine.Debug:LogWarning(Object)
In the Console

[coarse parrot]

You need to find and delete that file

And what did you put in event name?

[narrow cloak]

ah now it works

Think the error was making the build and test use the old one

[coarse parrot]

It won't. Unless you click on the Last Build button.

[burnt moth]

how do I get these into my udon thing

these are from a video

and I cant find them in the create node

where do I find targetGameobject

[dapper lion]

thats a varible you need to add (top left)

[burnt moth]

I found it thanks

but this work for toggle sound right

does this*

[dapper lion]

if the game object is set to "play on awake" then ye

[burnt moth]

yeah is there any quest compatibale invisble material on unity btw

[dapper lion]

ye?

[burnt moth]

like

[dapper lion]

i mean, if you mean "purely invisible" then dont have a material/mesh there at all

otherwise. dont stack them and you should be fine

[burnt moth]

but in unity they still look like something

but they'll be invisible in game?

[dapper lion]

depends

as i said, if you need it to be basically gone. disable mesh render

[burnt moth]

will I still be able to interact wiht it

because for some reason I cant see the trigger or interact with it ingame

[dapper lion]

as long as it has a collider

[burnt moth]

It has an orange thing around it in unity

[dapper lion]

make sure it has a collider

[burnt moth]

ok

[burnt moth]

it has collider and now I can interact with it

but it doesnt play any sound

and I have play on awake

[dapper lion]

where is the audio source? is it loud enough?

[burnt moth]

It's at max sound, I have a loud background music so I am going to try disable that and try

the audiosource is the child of the toggle button

[burnt moth]

he isnt saying anything

audio^^

Toggle button down here

[dapper lion]

make the min distence longer

[burnt moth]

the proximatity

?

[dapper lion]

what?

[burnt moth]

you said min dinstence

distence

where is that

[dapper lion]

by max distence

[burnt moth]

how big should I make it for testing

[dapper lion]

big as max

[burnt moth]

doesnt work

it plays now

but it plays also when start world

[dapper lion]

have audiosource disabled

[burnt moth]

it is...

for some reason it activates when I etner world

or soemthing

[dawn forge]

Do you have a script enabling it?

[burnt moth]

its working now but I need a way to when I click on the interact on a button that plays song that all other songs playing stops playing

I am not sure what to add to my current udon script

[dawn forge]

Two ideas:

Broadcast your "stop" event and have the other playing scripts have a bool/checkbox to accept that event or not and stop if so.

OR

Make an audio controller gameObject and its script will be able to access your audioSource gameObjects specified in your inspector, then directly work with the component.

Edit: See my script below, it can do both 🙂

Unity/Udon pro's, I need feedback because I am still intermediate to Unity, but if a gameObject is empty/null, I realized Udon shuts down even if I check it's null, but if it's null, I want to have it still work with listening for events.

If you use UdonSharp, I can DM you my sample.

using UdonSharp;
using UnityEngine;
using VRC.Udon.Common.Interfaces;

namespace Balphagore.BehaviourControllers
{
    [AddComponentMenu("AudioController")]
    public class AudioController : UdonSharpBehaviour
    {

        private AudioSource audioSourceComponent;

        public void Start()
        {
            audioSourceComponent = audioGameObject.GetComponent<AudioSource>();

            if (!audioGameObject)
            {
                Debug.Log("Audio Game Object is missing in script, will only listen for broadcasted events \"stop\".");

            }
            else
            {
                // Do we have the audio source component in the object?
                if (!audioSourceComponent)
                {
                    Debug.Log("Audio Game Object is missing an audio source component, please be sure to add and configure an audio source component in Game Object: " + audioGameObject.name);
                    this.enabled = false;
                }
            }

        }
        /// <summary>
        /// This runs when a user interacts with the object. 
        /// </summary>
        public override void Interact()
        {
            // Sends an event "StopAllMusic" to all component scripts of UdonBehaviuor.
            SendCustomNetworkEvent(NetworkEventTarget.All, "StopAllMusic");

            if (audioSourceComponent) _StopAudioSourceClip();
        }

        /// <summary>
        /// Stops the audio source from playing music - if playing.

        private void _StopAudioSourceClip()
        {
            if (audioSourceComponent.isPlaying)
            {
                audioSourceComponent.Stop();
                if (debug) { Debug.Log("Stopped Audio!"); }
            }
        }

        /// <summary>
        /// A callable event to stop the playing if allowed so.
        /// </summary>
        public void StopAllMusic()
        {
            if (debug) { Debug.Log("Stop event received!"); }

            if (allowStopEvent)
            {
                _StopAudioSourceClip();
            }

most likely the videoplayer. but could also be the 8ball table. acc its most likly the table. but its normally laggy for quest users

master is supposed to transfer in the newer videoplayer btw

[feral valve]

Is there a prefab I can download to make items grabbed be hats

[fading cipher]

Are VRCMirrors completely broken if an object is instantiated with a child object containing the mirror that is disabled?

It works fine in-editor, but when I enable the mirror child in-game nothing happens, and logging the mirror's .activeSelf after enabling it returns true

I'm aware that there's glitchiness with having an object disabled by default when you first join the world (you need to implement a self-disabling delay), but I was told that doesn't stand true for runtime instantiation

[stray junco]

hi all

(udon world)

is there any technique,video tutorial example or free vrc supported unity asset
for making vehicle to follow it's animated WayPath's ?

to be more clear i'm trying to make a RollerCoaster with seats
that when it's turned on it will carry users in their seating position
to their destinations but without shaking the camera of user visual field

thanks in advance

[dapper lion]

i think there was at some point, its on booth for 1000jp

but im not sure if its there anymore

[stray junco]

right

[solid sluice]

Any way of applying a image where the Script is? like on the inspector i mean

If any one knows something that can work use @ or send a privet message

Thx ^^

[wanton oxide]

Udon Toolkit does this iirc

https://github.com/orels1/UdonToolkit

you can look at the source for that

[willow nimbus]

so uh id like to replicate (at least partially) the old vrc_audiobank from sdk 2 for randomized environment audio but i have basically no programming experience.

how would i go about doing that?

[dawn forge]

I don't toy with the graph, but I have a good example I can send via DM for UdonSharp script. But you'll basically want to accept an array of audio clips, and an audio source component on the same game object you'd run your script on.

Here is a snippet from my script that basically picks a random track from array and plays it. I use Random.Range starting from 0 to the total length of the audio clip files available.

Also be sure to use GetComponent to populate your audioSource variable.

                audioSource = this.GetComponent<AudioSource>();

                int randomIndex = Random.Range(0, audioClips.Length);
                _LogEvent("Random Index:" + randomIndex);

                audioSource.clip = audioClips[randomIndex];

                _LogEvent("Playing clip: " + audioSource.clip.name);

                audioSource.play();

[willow nimbus]

ah that'd be great thanks, then i'll at least have a starting point even if i don't know how all of it works

[solid sluice]

Where?

[prime fossil]

how can i detect the platform again?

i wanna give a gameobject a different material for questies

but this shit feels like normal development where youd need to build everything yourself or even worse as theres no stackoverflowe

ah nvm

#if UNITY_ANDROID private bool isQuest = true; #else private bool isQuest = false; #endif

[prime fossil]

https://github.com/MerlinVR/UdonSharp/wiki/vrchat-api oi i found some documentation

[wanton oxide]

go to their documentation

then to the custom attributes section

this one

custom name

[solid sluice]

i'm checking

But how do they select the img?

[wanton oxide]

wdym select the img?

what are you trying to achieve

[solid sluice]

have a image on the inspector

Like a logo

[wanton oxide]

well thats exactly what they're doing no?

its all there

just need to dive into their code and see how it works

[solid sluice]

i'm getting a weird error when i try it

[solid sluice]

Do i need to import something?

i need Udon Tool Kit on the world, and the people that want to use my code need to have it to

i'm fine then

but thx

[wanton oxide]

if you want to use these attributes, then yes

i was telling you to look at their source so you can copy their implementation for drawing the logo

[mighty fjord]

You can load textures from file paths by using AssetDatabase.LoadAssetAtPath
https://docs.unity3d.com/ScriptReference/AssetDatabase.LoadAssetAtPath.html

But if you just want a header which displays some text you probably dont need to use an image

[solid sluice]

i'll try that one

[native fern]

Is there an equivalent to isActiveAndEnabled in Udon? I noticed that it is not supported...

[native fern]

ignore it, made my own 😉

internal bool IsActiveAndEnabled()
{
  return Utilities.IsValid(this) && enabled && gameObject.activeInHierarchy;
}

[dapper lion]

was there an input checker prefab somewhere at some point?

[grand temple]

Probably this?

[dapper lion]

oh epic, thanks

probably

[autumn birch]

Could someone send me a screenshot of a simple enable/disable udon script used to disable a map after teleporting from it to another? I intend to click on a door which teleports me to said map and I need all other maps disabled for optimization.

https://cdn.discordapp.com/attachments/232189169525325824/863531471419736074/unknown.png
I have no idea what I'm doing 😅 . And random uploads to test this script takes a good 10min per upload >_>. So far nothing works.

[pallid mango]

Udon shouldn’t be needed for this if you set up object occlusion fyi

[autumn birch]

I hate Occlusion, it doesn't work very well.. rendering pops back on sometimes based on view angles...

[grand temple]

huh? Do you have pimax or something?

[autumn birch]

Also I'm trying out JetDogs package with UdonSharp and well... I get a compile error... other people it seems don't have this problem so I don't know why I am...

no, I mean in the editor it does.

[grand temple]

or maybe occlusion culling is just set up wrong

you need to change the settings to match your scene and set certain objects to be occluder/occludee static depending on what they are. For example a chain link fence doesn't block your view, but the occlusion would have a hard time with it so you need to set objects like that to not be occluders

occlusion culling is always good to have, it is very powerful. If you are having issues with it, manual culling shouldn't be the alternative. It just means you need to fix the occlusion culling.

That being said, yes manual culling can still have a benefit. However it can cause a lot of issues too. For example if you have pickups with gravity, you need to make sure to freeze them if they are in an area that is disabled

[dapper lion]

@autumn birchwhat you can do is have the teleport button and the toggle button in the same button

[autumn birch]

Yeah, I just don't know how to create the graph needed to toggle things. Or untoggle which would need to happen at the same time.

[grand temple]

you just need to have a public gameobject variable and then do gameobject set active

[dapper lion]

"get activeinhierarchy"?

https://cdn.discordapp.com/attachments/232189169525325824/863531471419736074/unknown.png they have their graph

[autumn birch]

well in the screenshot above you see something similar to what I think I'm supposed to do >_>

[grand temple]

you're almost there, but you have nothing plugged into the get activeinhierarchy mode

[dapper lion]

everytime i do graph toggles. i always forget what order they have to go in lol

[grand temple]

so it defaults to the gameobject that the udonbehaviour is on, which is probably not what you want

so instead just plug in the stairwell object

that would make that graph work, but I'm not sure that's what you want either. That just toggles it. Based on the name of the graph I assume you want to just always enable it?

[autumn birch]

no, I want it to be enabled when I enter the door, and disable the room I came from at the same time

[grand temple]

so you need two gameobject variables

set one active, set the other inactive

[autumn birch]

how to set innactive?

[grand temple]

the gameobject setactive node has a toggle on it, just have it be false like this

and if you want it to be true, you just set it to true

[autumn birch]

that option doesn't seem to be there...

[grand temple]

because you have something plugged in already

remove that

[autumn birch]

so I don't need unarynegation?

[grand temple]

you would only need that if you want to toggle

[autumn birch]

tbh I don't know what that is

[grand temple]

unarynegation just flips a bool. If you input true, you get false. If you input false you get true

[autumn birch]

oh

wait so what do I connect get activeinhierarchy to?

[grand temple]

you don't need it if you're always setting it to the same value

I assume that this object will always enable A and disable B, while another object will always enable B and disable A

[wispy marlin]

How do I make a pickupable object that doesn't immediately just fall to the ground on play? I want it to be in the place that it's in when I submit the world until it's moved.

[grand temple]

set the rigidbody to iskinematic

[wispy marlin]

Thanks!

[scarlet lake]

People are talking in game and I cant hear anyone ?

[grand temple]

you may have safety settings turned on in the safety settings (try setting it to none) or you have voices turned down (it's a slider on the top right of the settings page).

I might be safety

Nope still not it

[steel bronze]

We have a popular world that uses audio boxes that boost the players audio by X amount when standing inside the collider. After about 60 people join the world the audio box breaks for about half the lobby. Does anyone know how to fix this and make it more reliable?

[fiery yoke]

https://docs.unity3d.com/Manual/class-AudioManager.html Unity has a setting for Max Virtual Voices and Max Real Voices, which make Unity limit how many Audio Source can be played at the same time. I think VRChat sets this to 60 so I would guess that this is the cause of your problem.

[solid sluice]

Why is this code not working?

{
public Animator animator;
public string anim;

public void override Interact()
{
    animator.Play(anim);
}

}

it's not playing the animation at all

[grand temple]

I would not recommend using that method to play an animator. Instead you should make a trigger variable on the animator. Then have an idle state and a running state. Then make a transition to running if the trigger variable is true. Then in your script you do animator.settrigger

[solid sluice]

ok then i can't make this into a prefab

i was trying to make a prefab that can run animations but ok then i'll work on my next problem

[manic yarrow]

I've got a UdonSharp script that moves objects from point to point using gameobjects, but it doesn't sync at all because I don't know how to make that happen.

I tried using the regular VRC object sync, but if a player disconnects while looking at the moving objects it ruins their pathing

You know how things kinda jitter for a second when you close VRChat?

well it transmits that jitter to everyone and breaks the whole thing

[grand temple]

It would probably help to call object sync.flagdiscontinuity. that tells people that it should teleport instantly without being smoothed

However if that doesn't work, I think your best bet is to have a synced integer and just use that integer as the index of the positions you want to go to.

[manic yarrow]

hang on, I'll show you the script as-is

[solid sluice]

@grand temple One question any idea how to make a Local Trigger with a Box Colider?

When a player enters the Colider it runs the code for everyone

[grand temple]

Just add onplayertriggerenter to an udonbehaviour

[solid sluice]

public override void OnPlayerTriggerEnter(VRCPlayerApi playerApi)

[grand temple]

That will also give you the playerapi of that player so you can do things like get the display name or branch only if they're the local player

[solid sluice]

This is what i have and is not local

[manic yarrow]

using UdonSharp;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;

public class Waypoints : UdonSharpBehaviour {

    public GameObject[] waypoints;
    int current = 0;
    public float speed;
    float WPradius = 1;
    
    void Update () {
        if(Vector3.Distance(waypoints[current].transform.position, transform.position) < WPradius)
        {
            if (current != waypoints.Length)
            {
                current = current + 1;
            }
            if (current >= waypoints.Length)
            {
                current = 0;
            }
            transform.LookAt(waypoints[current].transform.position);
        }
        transform.position = Vector3.MoveTowards(transform.position, waypoints[current].transform.position, Time.deltaTime * speed);

    }
}```

This is the script, doesn't have any networking built into it

[grand temple]

Thats correct, but it gives you the playerapi. You can check if that player is local

[solid sluice]

and that will be Player.Local?

[grand temple]

Player.islocal

[grand temple]

Oh I see, I assumed you wanted it to teleport. If not then I think vrc object sync is your best bet. I'm not entirely sure what issue you're talking about though, could you take a quick video?

[solid sluice]

but if i get that on a If it will be true every time because all the players are local

[manic yarrow]

Alright, give me a second to record it

[grand temple]

No, they are not. Only one player is local, that is the player that you control and move around

[solid sluice]

i'll check

So i need that on a if

[grand temple]

If another player enters into it, islocal will be false on your computer. On their computer, it will be true. Everyone is running this code independently

[solid sluice]

Like if VRCPlayerApi.Player.islocal = true or something like this

[manic yarrow]

You want the video with the object sync bug, right?

[sullen haven]

Kőolaj

[grand temple]

Yes, I'm not sure what you're referring to

[manic yarrow]

I just need to rebuild it with the object syncs enabled, give it a moment

[grand temple]

Does that happen specifically when the master disconnects? Or is it anyone

[solid sluice]

So when i try VRCPlayerApi.Player.islocal Player is not a thing that VRCPlayerApi has

[grand temple]

It's just player.islocal

Player is a vrcplayerapi variable already due to the function that you are in, there is no need to specify vrcplayerapi

[solid sluice]

The name 'player' does not exist in the current context [Assembly-CSharp]csharp(CS0103)

[grand temple]

Is this inside the onplayertriggerenter event?

[solid sluice]

Yep

[grand temple]

Oh you renamed it to playerApi

Whatever variable you received from the onplayertriggerenter, that's all that matters

[steel bronze]

Is there a way around this?

[solid sluice]

i don't get it sorry

this is what i'm trying

[grand temple]

If udonsharp is giving your trouble, I would recommend trying udon graphs

[solid sluice]

i don't understand graphs

[grand temple]

Then watch some tutorial videos from vowgan

[solid sluice]

i don't know who made it but i can't even create a variable with it

it's to hard

[grand temple]

Watch tutorial videos from vowgan

[manic yarrow]

Hmm, I can't seem to recreate it for some reason, the jitter still happens but it didn't affect it this time around

Still, I feel like it'd be a better idea to include the syncing inside the script

[solid sluice]

i can't use a graph because this is for a prefab and i wanna run a different code when is done, so this code is calling a different UdonBehaviour when is triggered

[grand temple]

Vowgan also does tutorials in udon sharp

[grand temple]

I'm guessing it might be because when it transfers from one player to another, it tries going to the wrong location. If you just sync that current integer I think it would work

[manic yarrow]

how do you sync specific stuff like that?

All I could find was setting a sync mode for a whole script

[grand temple]

add [udonsynced] before the variable

[manic yarrow]

before int or between int and the name?

[grand temple]

before int

this is what's called an attribute

[manic yarrow]

do spaces affect it or anything? Just want to make sure since c# isn't really my thing

[grand temple]

yeah make sure it's exactly [UdonSynced]

[manic yarrow]

[UdonSynced] int current = 0;

[grand temple]

yep

[manic yarrow]

Oh yeah, another thing

someone told me that teleporting every frame is broken right now, is that true?

[grand temple]

teleporting an object is fine, it's teleporting the player that you shouldn't do

[manic yarrow]

Oh, someone told me I'd need to teleport the player around

Unless there's a smarter way to make moving objects people can walk on

[grand temple]

the open beta fixed the biggest issue with teleporting every frame, but it's not the only issue

[steel bronze]

So technically if I changed this setting then my issue would be resolved right? Or would vrc take it back to default

[grand temple]

and besides, keeping the player on moving objects is very complicated math, especially when the object starts to rotate. I'm not sure if I have the energy to go step by step on that big of a project

[manic yarrow]

By the way, just made a new build with the synced variable and it makes the objects behave weirdly

that integer is counting up through the list of waypoints that the objects have to pass through

[grand temple]

define weirdly?

[manic yarrow]

by syncing it, it makes the objects skip a bunch of waypoints in order to match the other people

[grand temple]

it's probably being weird because everyone is doing this code. Try doing if (!Networking.IsOwner(gameObject)) return; at the start of update. That will stop running any code if you're not the owner

[manic yarrow]

Let's say an object has to go around a corner with these 3 checkpoints

If the object has already passed checkpoint 2 when a person joins late, the object will go straight for 3

because the original object was on its way to 3

[grand temple]

yeah, but it has objectsync so it should be on the path from 2 to 3, right?

unless objectsync is not working

[manic yarrow]

Oh, this is in combination with objectsync?

[grand temple]

of course

[manic yarrow]

I was under the impression it was replacing it for some reason

[grand temple]

the reason to sync the current target is so that it can be safely handed off to someone else when the owner disconnects

[manic yarrow]

should I leave collision ownership transfer on?

For some reason I feel like I shouldn't

[grand temple]

probably don't want that

[manic yarrow]

Alright, seems to be working now

It's a shame that making a moving object that you move relative to is so complex though

you'd think unity would have some kind of moving platform component

[dawn forge]

Hey, so I am using VRC Pickup script to allow a player to manipulate an object, but I want to freeze its position only on the y-axis so they can't pick it off the table, only move on x-z, but it doesn't seem to respect the Rigidbody's freeze setting. I am looking through docs but can't find anything that may help?

[dapper lion]

try this

rigid body freezing means something elser

[dawn forge]

Thank you!

[autumn birch]

what are the nodes needed for just a simple 'play sound' when interacting with an object? I got interact ->, AudioSource Set enabled' with the audio source Door sound in the instance slot. Audiosource set to play on awake so it only plays when the world loads and not when it's on my doors >_>

[cold raft]

That sounds about right yes interact to set active on the audio source, and set the audio source to disabled in the editor so it wont play on world load

[feral valve]

Wheres the best place to learn udon and udon sharp that's not outdated?

[still valley]

did vrc broke?

udon

[dapper lion]

no not yet

[dapper lion]

vowgan, most of his stuff still translates well and if somethings too old. hel repost

i think theres more udonsharp youtube channels popping up tho that might be more updated

but i avent been keeping track

[feral valve]

Alright ty

[fading cipher]

When attempting to do my item spawn pretty far away from my VRCWorld object, the logs are saying it should be spawning at what looks like the right place, but the item is nowhere to be found... https://i.imgur.com/0A1ks35.png

Is the VRCWorld automatically respawning it because it's so far away? Is there a place I need to up a value to fix that?

ohhhh

I know the problem

[autumn birch]

not working btw

[formal leaf]

how do i use udon and the animation controller stuff, i want to play an animation when i interact with a button (it's just the button moving)

[slim hound]

AudioSource.PlayOneShot and you can disable Play On Awake

[scarlet lake]

i have a python script on my computer that gets a string from a website and i was wondering if it would be possible to display that string in a vrchat world?

its mostly just being able to manipulate a variable of that string not so much display it

[cold raft]

well if you have a ui text component you can just set the text to the string when its value changes

[scarlet lake]

but can a vrchat world read a value of a string on my personal computer

[cold raft]

it should not be able to do that no

[scarlet lake]

my plan is for a string on a website to be displayed in the vrchat world, but to get that string you need a python script

is this possible?

[grand temple]

best you can do is focus an inputfield and then paste it in

[scarlet lake]

would it be possible to send a text message from a vrchat world to my personal computer so i could run a script using that text?

or can data from vrchat worlds not leave the vrchat world

[cold raft]

well there are some trickly ways, for example you are able to load in extenral urls (if the user has the allow untrusted urls checkbox set)
now you could use the query string part of the url to pass data to the enternal server

[scarlet lake]

so a button with a url that parses text from an input box to an external server?

[cold raft]

yes like how the video player works, you enter a url and it tries to load a video at the endpoint, you can have no video there so the loading of the video fails but than the request is still made
you can even hide the video player and give it no audio sources so the users in your world would never know what happens in the backend

and to actually load data into a world from an external source, often video players are used, not with normal video but with just data, like colored pixels representing information, i think you can parse individual pixels in a video.

[scarlet lake]

is there a straightforward way to pass a string through a url without having to create a website?

hi yall i hope this is the right place to ask this, does anyone know how to add a keyboard so you can search up videos like this one on the pic?

[cold raft]

not that i know if

[scarlet lake]

i think i managed to make a temporary solution

[cold raft]

nice

[boreal plaza]

I cant do getcomponent in a udonscript? or am I an idiot?

[cold raft]

You cant do getcompnent<T>

[flint urchin]

You can

but not on Udon components

or VRC ones

[cold raft]

But getcomponent(typeof(T)) does work

[flint urchin]

You can do GetComponent<UdonSharpScriptClassName>().Method()

Restart Unity

You can manually install Cinemachine via the Package Manager too if the error still persists

[obtuse valley]

udon like the food right?

[floral dove]

?whatisudon

[hidden marten]

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

[soft mountain]

So, question: you know how Cyan's climbing prefab stashes the handholds behind the player's ears? What's the best way to go about doing that in Udon?

[grand temple]

all you have to do is set the position of an object to the local player's tracking data every frame while it's not being held. You would do that with the update event and with playerapi GetTrackingData

To add an offset so that it's not exactly on the player's head, you can multiply the player's head rotation (as a quaternion) by a fixed offset (vector3) to align it with the rotation of the head. This will make the offset be effectively in the local space of the player's head

[whole rain]

How would someone go about comparing the size of 2 Vector3s? I have a dynamically scaling object that I want to set max/min boundaries on

I've tried comparing magnitudes (and sqrMagnitudes) but it's obvious to me that I'm dumb and that's not what magnitudes do

[grand temple]

depends exactly what you want, but first thing that comes to my mind is that you would split up the vector3 into it's component floats and run mathf.clamp on it against two other vector3s which have also been split up into their components

[whole rain]

I'm creating an AudioVisualizer but writing most of the code myself (though it's definitely based off M.O.O.N.'s tutorial video for the base of it). I have a script for changing Scale, and I want a high and low threshold. Therefore I have to check every frame if the object is above or below my max/min vectors. The more I read, I feel like magnitude should be correct (just measuring the length of the object should get the job done) but of course, that isn't happening and I'm worried I'm going about it wrong

I feel like setting 9 variables (maybe 12 actually if I combined the 3 from each vector3 object and then compared the 3 results) might work but I'm worried about performance (especially on Quest since I can't test that)

[grand temple]

do you have to check every frame always? Or would it work if you only check while interacting with this object?

[whole rain]

Each object updates its scale according to the SpectrumData it receives from the master object every frame.

[grand temple]

oh I see

well do they actually deform on every axis? Or just one axis

[whole rain]

For now, every axis. I wouldn't mind adding some functionality in the future for altering specific axis, but it's much easier for now to do every axis

[grand temple]

well I was meaning that if you're worried about the performance cost of doing this on every axis, you could just do it on one instead. It would be simpler

actually wait no, there is a vector3 lerp function. That's probably what you want instead of a clamp anyway

since the spectrum will just give you a float, you can plug that directly into the lerp

[whole rain]

True, but for objects I have planned they would need to update on every axis anyway (like my 3D stars) so unfortunately it's not an option to limit all objects to one axis

I'm currently using lerps to move between the current scale and the next one, but my problem is seeing if my next scale is bigger than my max

[grand temple]

where are you getting the next scale from

[whole rain]

It's a public Vector3 variable that can be set on the object

[grand temple]

so then clamp it on start

though maybe I'm misunderstanding, I'm not sure why you would want to make a maximum to that at all if it's something you manually put in

[whole rain]

The point of the maximum and minimum vectors is to stop objects from getting too large/small. The data from the AudioSpectrum isn't predictable, especially when you don't know exactly what clip (in my use case song) will be playing.

I'm still pretty new to all of this, what exactly is clamping?

[grand temple]

ohh, does spectrum data provide a value that is not strictly 0 to 1?

I'm not sure what it gives, is it something random like 50?

[whole rain]

Tbh, I do not actually know what values specifically are in the float array the spectrum is in, but it's more than 2 options for sure

[grand temple]

try running a debug log to see what value spectrum data is giving you

Then you should do an inverselerp on the spectrumdata first. Once you know that, you can use inverselerp on the spectrumdata and define the minimum and maximum. For example if the spectrumdata varies somewhere between 0 and 50, you would run inverselerp(0,50,value). Then you plug that into the vector3 lerp and it will be normalized and clamped properly

[whole rain]

I'm not actually sure how I would implement that, because like I said every song will be different. Heck, even different areas of the spectrum will be different. I also don't know how I would use that to set limits on the scale of my objects. Should I try and give a brief explanation as to what my script is doing exactly?

[grand temple]

there must be some kind of standardized scale that spectrum data happens on, you need to find that out.

[whole rain]

The SpectrumData is just an array of floats set by Unity using GetSpectrumData. I'm not entirely sure what the math is here, but each float corresponds to frequencies in increasing order and their (I'm assuming) volume. From the debugs I just did, I saw as low as 0.00000x and as high as 6.x, but that's with my volume set lower than what others may use, and is also only on #0 corresponding to lower frequencies.

This data then gets used to alter the scale of my object, along with a mulitplier to get more usable data. I'm using UdonSharp, so that code looks like this Vector3 endScale = new Vector3((currentScale.x * SpectrumData[spectrumLocation]) / 2 * multiplier, (currentScale.y * SpectrumData[spectrumLocation]) / 2 * multiplier, (currentScale.x * SpectrumData[spectrumLocation]) / 2 * multiplier);

In order to have a hard limit on my objects size, I need to actually compare sizes and then stop the lerp that follows this from happening

[grand temple]

any adjustments you do to the source should be done before it ever touches the vector3. You're just doing the same code 3 times for no reason

I'm telling you, just run inverselerp on the number and then run vector3 lerp

that will give you the most amount of control and you'll be able to properly clamp it and rescale it to whatever you want

[whole rain]

I'm not adjusting the source, I'm creating a Vector3 using values from the source. I have to do it 3 times as each vector may be different. If my object is 2 3 2 for example, I need to scale each one individually as the results from y would be different from x and z

[grand temple]

that's what vector3 lerp does

the inverselerp clamps and normalizes, the lerp applies it to the vector3

[whole rain]

I'm really confused as to how to introduce hard caps into that solution. Every object may scale differently and have different multipliers and max/min sizes.

[grand temple]

when you use inverselerp, that normalizes it to a 0 to 1 range. That means when you plug it into the lerp, it will properly respect the min and max. It will never go beyond the max or below the min

the reason you're having issues right now is because you're just blindly multiplying, so your "max" isn't really a max, it's just another multiplier

[whole rain]

The max doesn't change, it's never used in any math. It's an arbitrary Vector3 set by me per object. All I'm trying to do is get a value out of my endScale, or what the object wants to change to, and compare it to my max and minimum Vector3s. Everything before that is irrelevant in that exchange.

Inverselerping is actually an excellent idea to help me normalize my data even further than the smoothness value already does, but it wouldn't change anything about that comparison that needs to happen after the scale my object wants to change to has been determined.

[grand temple]

but my point is that you don't need to worry about checking the resulting vector3 if you are already normalizing the input float. If you run that through a lerp, you can be confident that it will never be greater than the max

[whole rain]

I respect that, and I'm sure that is what other visualizers have done in the past, but I'm trying to set hard limits to ensure objects never get too big or small no matter what. It's the last line of defense, making sure that no matter what it is impossible for objects to be too large or too small

I just said the same thing twice...

I know inverselerping does set a cap on that, but as the person placing the object I have no control over what that cap is. If everything ends up working well, I'd also like to package and share this visualizer I've made too so that it can be used by others who may not know how or want to make one.

[grand temple]

yes you do have control over that cap. That's the B input

[whole rain]

The problem is that it's an arbitrary value that isn't easily understood. Having actual Vector3s means it's easy to see how big or small the object can actually get

[grand temple]

if you've seen around 6, I would guess the max value is 10

[dawn plover]

Hello! I was experimenting with the VRC Object Pool for a game I want to make, but I've noticed it pulls out objects from the pool in order and I need that the object pool takes the objects outside randomly, is there a way to do that or I need to make a custom system just for that?

[dawn plover]

No one can help me? I can't find enough information about this

[dapper lion]

im pretty sure object pool was randomized by default. but i eventually gave up using vrc object pool all together so i can have object spawn in order lol

[slim hound]

What are you trying to do exactly? if you need it to be random there is a function to shuffle the object pool

[dawn plover]

It's a card game, so I have all the cards inside the pool and I want them to be picked randomly from the pool

[dawn plover]

I've been doing a lot of test and as far as I can see they only spawn in the same order every time, and it use the order of the VRC Object Pool

[dapper lion]

huh. i mustve done something wrong that you probs want lol

what is your set up current?

[dawn plover]

I guess so lol
For now I'm just using the prefab from VRChat Examples, I tried to see the nodes inside VRC Object Pool but there's nothing to randomise the spawn

[slim hound]

If you search for VRCObjectPool and in its available nodes you should be able to find it

If not you likely need to update your SDK

[dawn plover]

Oh, I don't have it, and yeah, I have an older SDK, I was sure it was the most recent one but I guess I was wrong lol
I'll try to update then, thank you for the help 😄

[manic yarrow]

I've created an override animation for a station in a world I'm working on, and while it works perfectly in 3.0 avatars, 2.0 avatars get stuck in the proxy_stand_still animation instead of the custom animation.

I copied the default chair controller to do it, which I thought would be enough

but as I said, 2.0 avatars don't sit.

[pallid mango]

Is the controller using AvatarVersion to transition to two different states depending on version?

[manic yarrow]

give me a second, accidentally started a new build 😅

[manic yarrow]

This is what it does

[obtuse agate]

@whole rain That’s a good question. I don’t how GetSpectrumData implements FFT bin exactly, but my guess is, the maximum value of spectrum data is either the length of the array (for example 4096) or its square root (for example 64). However you won’t see this maximum in practice, since it can only be achieved with some artificial waveform

[pallid mango]

I’d skip the seated check. If they are running the controller they are sitting

[manic yarrow]

weird, that's what the default seat is doing

[pallid mango]

If they are getting stuck in the first state I would try toggling write defaults

I don’t know if that will help but I’ve seen some avatar controllers get stuck on the initial state in some cases with no write defaults

[manic yarrow]

I'll try removing the seated check first

where's the option for write defaults, in the controller or on the animation?

[manic yarrow]

Hm, that causes 2.0 avatars to constantly wiggle between the seated animation and the standing animation

[pallid mango]

Somethings not going right there

I didn’t think av2 avatars could continue to propagate through a controller anyway
