paper plinth
#

so my idea was this because I like magix music maker
was to create the building blocks of audio as actual cubes and let folks use dials and switches to transform the audio clips and put them in order

#

and multiple folks within that space could put the blocks in different places

polar sail
#

A sequencer

paper plinth
#

yeah

polar sail
#

That would be cool

paper plinth
#

like a multiplayer magix

stoic mountain
#

I assume this
transform.Rotate(rotationAxis, speed * Time.deltaTime);has no chance to trigger an overflow by rotating an object too much ? (should stay -180/180 right ?)

polar sail
#

magix is horrible but you do you

paper plinth
#

no

#

lol

#

yeah

#

I have reaper installed

#

and there's a tutorial here

#

just need to get to it

stoic mountain
#

are regular Monobehavior scripts allowed btw ? for object for which network sync is irrelevant ? (here its a propeller)

polar sail
#

My understanding was no scripts that aren't shaders

#

All udon

stoic mountain
#

oh, ok ill convert it then

polar sail
#

If i could use monobehaviors I'd be so happy

#

I'd have a working synth with wave deformation and everything by now

#

But instead i have to have three samples just for one note

#

Granted, they're tiny, but still

dapper lion
#

what about soundfonts. did those ever get allowed into udon?

polar sail
#

Unsure

#

Wouldn't solve the current problem I'm having though

#

I need a slice of audio to be able to be queued up seamlessly, but that's not possible like it is in regular unity because i don't have access to the audiosettings class

stoic mountain
#

Sanity check : im trying to have a plane fly in a straight line and pass through a random point. To do so, I use a dummy object with UdonBehavior and synced position checked, move and rotate it randomly from in a .isMaster player script, hoping that this object position will be synced to that new position for all players, then I tell all players (through a network custom event) to put the plane at this object's positions, using this object orientation as forward (flattened ofc) then move it back and start moving it.

Im using an object as the point to align with as I didnt find a way to send variables (like a position) to other players.

Is this approach dumb ?

polar sail
#

...

#

Maybe i should just give up on vrchat honestly because everything you said just bounced right off my little skull

stoic mountain
#

tbh I dont feel really helped with vrc/photon network stuff

#

I feel like I would do better with my own net code :|

polar sail
#

Honestly i just want to make things

#

Vrchat seemed like a good platform but ALL of my experience is with code, being so limited makes my head hurt

stoic mountain
#

Same here. My dream is for vrchat to become more like a simple plugin (managing avatars, main menus, friends & so) leaving the rest of your unity project "vanilla" so you could code your stuff however you like.

dapper lion
#

it was like that

floral dove
stoic mountain
#

That wouldnt be a bad buisness approach too, being a unified multiplayer/avatar service provider that any developer could work with for their own games

stoic mountain
polar sail
#

U# is still limited by the fact that it's only a portion of the unity engine

dapper lion
#

theres also altspace, which works from scripts that you host rather than the game hosting the scripts

stoic mountain
#

isnt altspace dead ?

dapper lion
#

nah, its just full of smart quest users. its terrifying

#

u# is limited because udon allows so much. the problem when unity scripting was allows was because of the possibility of malicious usage and many other problems

stoic mountain
#

I tried it the other day and checked "popular worlds" and they had like 3-4 players at most on them. Maybe I missed something. Also VRChat avatars spoiled me, I dont like altspace very generic avatar style :s

dapper lion
#

yea, as i said. alt space is where all the smart people/normal people who have a quest hangout

polar sail
#

I know why I'm not allowed to use all of unity but it still makes me moderately upset that so much of what unity offers isn't accessible even though it's right there.

floral dove
#

@polar sail - if you would like to request the use of particular aspects of Unity, you're welcome to make a Canny feature request

fading cipher
#

Are the in-game positions and scale perfectly equivalent to real meters and cm?

polar sail
stoic mountain
#

Tbh the script limitations, I can get used to it. The 0.25s sync rate, added to the unexplainable 2 to 4 seconds of lag between players ? that really limits what can be done :|

floral dove
fading cipher
#

Sync does suck...I made a custom grab script that piggybacks off of VRC_Pickups and it has a good half second or more of lag in following a person that’s holding it lol

polar sail
#

Thank you momo

dapper lion
#

he got you there with the audio flexibility

stoic mountain
#

tough Ive been told you'll be allowed to force sync on request in a future version, so you could get a higher rate of sync for some objects if you code it I guess

dapper lion
#

had to glitch some of my audio matrixes in

polar sail
#

Just let me make a sine wave

#

Instead of making one with audacity and sampling a 500B file

floral dove
#

how would you like to make a sine wave?

hasty hare
#

is it normal that user layers in-game don't retain the names given to them in the editor? just noticed they become user1, user2, etc. when using LayerToName

#

I get the correct layer name testing in editor though

polar sail
#

Unity has an event that exposes an audio filter that you can write to the data stream in

floral dove
#

OnAudioFilterRead?

polar sail
#

So you can set a sample size and calculate a waveform and send it to the audio buffer in real time

#

Yes

#

I couldn't find anywhere to reference that event

#

Could be nasty anyway because it would likely require constant writing to the data stream

floral dove
#

If you'd like us to add support, you can request access to OnAudioFilterRead on the canny. If you think it's too nasty to use then...maybe don't? Not sure what you want here.

dapper lion
#

wasnt there a waveform = sine?

polar sail
#

It works perfectly fine but I'm not sure if an event that calls every frame is good or not, but that's more of something for the guys on the dev team to look into i suppose

#

Granted you can access the update event though, so... yeah it would be fine nvm

#

I did put it on the canny though, thank you @floral dove, MIDI support and procedural audio would open up a ton of doors for cool stuff in the future.

#

MIDI support alone was enough for me to make a working sound generator in less than an hour

Hello ! I'd like to ask this question before messing around without any ideas:

Is there anyways to make a player voice being heard inside of a collider if the said player is inside another one ?
I made a picture on my phone to visually explain what i mean kind of.

By default, the voice range is smaller than the room 1
I'd like a player (or multiple, whatever) to step into a precise zone on the room 1 ( the pink square) to be heard equally everywhere in the room 1 only and not outside of it so people in the room 2 can talk in peace ?

I'm having troubles putting words into what my brain is thinking I hope i'm clear enough ;-;

41088.png
dapper lion
#

@lilac hatch so not being heard between walls?

fading cipher
#

I don't think there's an audio occlusion option rn, so you'd have to set the player's voice falloff for other players I believe

#

So each player in room 1 would be doing a check to see if there's a player in the pink zone, and if there is, they'd up the falloff distance on that person's voice until they leave

#

I'm not sure how to modify that stat, but I know someone else has made walkie talkies for players by making it so the other person holding the talkie gets their falloff set way high

#

So I know modifying voice falloff when certain criteria are met is possible

dapper lion
#

@fading cipher there is a way to make audio occlusion

#

just making sure thats what niyah is asking

fading cipher
#

You can do audio occlusion 👀 is it heavy to process?

mint spade
#

I've seen exactly this work though for the open mic night map, voice amplification for on stage, falloff before other room. Rest of room is normal, so it is possible.

dapper lion
#

@fading cipher no this is done via udon and unity does the audio matrixing so its basically no performance dither at all

lilac hatch
#

ye basically, that's what i'm looking for right now !

fading cipher
#

three different people have made suggestions

#

So you can't say "that's what I want"

dapper lion
#

ok, so 3 people i have to remember to send the audio occlusion script to 😅

fading cipher
#

there are 3 thats lol

lilac hatch
#

wupsie

#

I'm slowly reading, hold up

fading cipher
#

o/

#

An audio occlusion script 😍

dapper lion
#

niyah, in about 4-6ish hours, ill probs be able to send you a script, but if i forget. plz message me if you can

fading cipher
#

Yeah I have absolutely no use for that but as a person obsessed with realistic things, that sounds glorious

dapper lion
#

@fading cipher also remind me. i totally agree. realistic audio matrixes are cool

fading cipher
#

Yep, I've put a reminder in my phone to remind you lmfao

#

o/

dapper lion
#

thanks lol

lilac hatch
#

So yeah, the idea is to have a scene/microphone in the pink area ( Let's stick it on a static object for the moment) and being able to be heard in the entire room but having a big falloff/sound cut when exiting the area, i'm very unfamiliar with the technical terms ;-; sorry

#

Audio occlusion it is then

dapper lion
#

but yea, you can alter a lot of audio points like voices, avatars, low pass, and what layer you can occlude audio from

lilac hatch
#

"I've seen exactly this work though for the open mic night map, voice amplification for on stage, falloff before other room. Rest of room is normal, so it is possible."

Exactly that tbf 👀

dapper lion
#

i still need to figure out how to make a handhelp radio/phone so you can talk to people from afar

#

yes, you can also make collider that activates the voice mods scripts so it amplfies your voice

i need help again..early i asked how to fix my Mirror Trigger Zones: Basicly a Mesh Collider that says a script when a player goes in and back out to turn off the mirror and back on when he goes back in. Problem was that props or button inside or below that collider was not pickup or interactable. Now someone said to put it to mirrorreflection. Which works but now the trigger zones are triggered by everybody and not only playerlocal xD

which of these i have to select in playertrigger to get both to work?

Hello everyone I'm recently creating a world to share musical instrument performance using MIDI with people.
My goal is to make sure that one person plays a midi piano and everyone can appreciate it.
My first attempt was as follows. Since midinoteonevent occurs only for the person playing the MIDI, I create a sync int variable to store the int value for the number of what button pressed and then use sendcustomvent to play the note of the number stored in the sync int.
This worked fine for multiple notes locally, but from the perspective of other players receiving sendcustomvent, the playing note was played one beat late(if i play 1234, receved 123), and even if several notes were pressed simultaneously, only one to two notes were played.
Maybe I did something wrong?
In a different way, I created each customevent corresponding to 88 piano keys and played a different customevent for each button (without using the int sync variable). At this time, the musical performance was very well delivered.
However, creating a custom event corresponding to the keyboard was a very difficult task. I want to add more features, but I think it's too hard to do repetitive tasks.
If you have any ideas or am doing something wrong on this issue, please answer me. and thank you for reading my question 🙂

Is the maximum resolution for the video player the vertical or horizontal resolution, or both? Like if I want to fetch 480p streams, should I set that to 640, or 480?

I'm trying to determine if two UdonBehaviors are equal, but I'm having a hard time finding the right node. I dragged a noodle out from the input to my branch, and typed in UdonBehavior and found UdonBehavior[].Equals but that's an array if I'm not mistaken and in any case, when it creates the node, the node says the type is IUdonEventReceiver[] which is also an array and I'm not sure if it's the same type as an UdonBehavior.

#

Also the two inputs are strangely named differently, which one would not expect if one were trying to compare two variables of the same type:

unknown.png
#

I would also expect to get something if I were to drag out a noodle from my UdonBehaviors and search Equals, but instead search finds nothing:

unknown.png
#

Well clearly that's the wrong node because I can't even connect my UdonBehavior variables to the top input.

grand temple
#

Just use object equality. they all inherit from that

old karma
#

A random one as its bugging me and should be a thing but probably is not you never know. For local testing we can have multiple clients for sync testing but is there away to test late joiners in local testing as my current method of bothering someone else just to test late joiner syncing is a pain. edit:This probably belongs in world development now that i think about it but blehh

jaunty schooner
#

@grand temple What's the difference between that and ReferenceEquals? Cause I did some googling to see how it's done in Unity, and someone said ReferenceEquals is the fastest and I found a node for that, which seems to work.

compact stirrup

has anyone had a world build and test fine but fail to build and publish?

harsh magnet

What's the error you're seeing?

#

@compact stirrup ^^

#

Exception Message:
An exception occurred during EXTERN to 'VRCSDKBaseVRCPlayerApi.__GetPosition__UnityEngineVector3'.
Parameter Addresses: 0x00000010, 0x0000000C

#

I have 2 udon graphs. The first sets a vrcplayerapi on the second during runtime

#

it's complaining while compiling to build that the second doesn't have a variable initialized, even though this error never happens during runtime

#

I've published this build in previous versions with this same script setup, as well

#

and it builds and tests fine

harsh magnet
#

Does the second graph have a null check for the VR player API?

compact stirrup
#

no, but I've never had to before in order to get it to upload

harsh magnet
#

If they both start at the same time there is a chance you're seeing a race condition where graph 2 executes before graph 1 is finished populating the input

#

I can't speak to why it worked before, perhaps the graph compiled in such a way you got lucky

compact stirrup
#

hm, that makes sense, I'll add a null check

harsh magnet
#

Null check plus maybe custom event to fire off the second graph once you're sure graph 1 is complete

compact stirrup
#

The way it is setup, the first graph has a start event to disable the udon behavior of the second object

#

to set enabled to false

#

it is a object that I clone in my world when the first object is triggered by players

harsh magnet
#

You could just have the object you clone set to false initially, then enable it as the last step of graph 1. Disabled objects won't run any graph code until they're enabled

compact stirrup
#

that's the checkbox next too "Udon Behavior (Script)" in the editor?

harsh magnet
#

Yup. That or the object itself at the top of the inspector

#

Your can disable the whole game object, which will disable everything attached to it

#

But you can still clone the object and turn it on at your leisure

#

This is useful for things like RigidBody that can't be disabled by themselves, but you can disable the whole object and get the same effect

compact stirrup
#

oh, that saves me some dumb code segments, thanks for the tip

harsh magnet
#

Sure thing! Good luck with the graphs.

compact stirrup

that worked, and I was able to trim off some excess code

Thank you, I've looked through and searched various forums but nothing so far.

#

I saw that post from a month ago mentioning it. I didn't even know it wasn't possible before, and now I don't know if it is possible now, or how to work around that since I wrote my code assuming anyone could set a synced variable and now I find out only the owner can, but then I immediately discover that maybe even they can't change it if ownership has just been transferred, so now I gotta redo my code to use an event to toggle a button instead?

#

Btw, its really hard doing this networking stuff without solid docs explaining exactly when ownership will be transferred. Like, I expected ownership of my power button to be transferred when someone clicked it, but apparently it's not being transferred because that synced variable isn't being set unless the owner of the instance clicks it.

#

And yet the code for the video players that I've been tweaking had given me the impression that the person that entered the URL would be the owner of it. But that's a click. So if clicking didn't transfer ownership for my button I shouldn't expect it would do so for the video player either. And yet, the code for the video player checks for owner... But why if ownership would never be tranferred? Why not master?

#

I guess I should just skip the whole setowner thing since I don't know if I can set the variable immediately after changing ownership and just have the player that interacted send an event to notify everyone the button was clicked and then have that event toggle the synced variable.

#

And since only the owner will actually be able to toggle it...

#

Hm.. come to think of it, I don't know what happens if a player that is not the owner tries to set a synced variable. I mean I think I know it won't be synced.. But will it change locally? That would cause a desync... Though I suppose if the master is keeping sync any desync would only be momentary if it could happen...

#

Hm... I guess it should be fine.

#

Well I decided to check the the owner was the one that is receiving the event anyway. Just in case anything wonky happens if a non-owner tries to set the variable.

#

Worth noting that I could not find SendCustomNetworkEvent or IsOwner by typing them into the quick search box, and SendNetworkEvent isn't under Networking, which is where I'd expect it to be, its under UdonBehaviors.

#

And while I understand that perhaps Networking is Unity Networking stuff and this is specifically an Udon thing, if I'm looking for networking commands the first place I'm gonna look is under Networking.

#

Well, hopefully this new event based approach works. The button above was a piece of cake compared with trying to figure out how to sync up the visibility state of two floppy disks, one in the drive, and one in a player's hand, which may or may not have different owners. I'd written my previous code on the assumption that anyone could set a synced variable. And since I can't count on SetOwner allowing me to immediately set a synced variable I can't use that. And I figured if I tried to make it so only the owner of the floppy could set its visiblity state that with everything else going on in the code it was ripe for problems, so I tore out the synced variable stuff and used events to set visibility for the floppies instead.

#

Forgot to show how the variables were setup in that first script...

unknown.png
#

Speaking of which, it would be good if the collapsed view would say like "public synced UdonBehavior" or whatever, so when the panel is collapsed you can still tell the settings.

#

Of course that would require the panel to be wider... So maybe make it an option.

#

Hm, I just realized I have no idea if late joining players will have these visibility states synced for them. I thought I read something about late joiners getting events they missed but then again, I also thought I read something about being able to prevent that. But I can't recall seeing anything about that since. So maybe I'd have to handle late joiners manually and send them any critical events? I'm not even sure how to tell if someone is a late joiner or if that's even an event available though.

jaunty schooner
#

Oopsie, had a bug in the floppy disk ejection subroutine. I was still trying to show the disk again using the synced variables. That's event driven now too.

void ridge
jaunty schooner
#

Is it necessary to have prefabs on the prefab layer? I'm having some performance issues in my world and I'd like the prefabs not to collide with eachother, but still collide with the world. I was considering placing them on the Player layer, as the Player layer collides with most everything except other Players.

paper galleon
#

No prefabs can be on any layer

#

They are just saved objects being used its not a big issue

jaunty schooner
#

Okay, wasn't sure if their code checking if you could pick the item up would have a check for that, or if whatever method they're using to sense the player colliding with them would be affected. Like, if the player's hand can't collide with the player layer then maybe it couldn't sense the trigger when the object enters the hand trigger, if that even is how they handle that.

harsh magnet
#

For now the pattern you want to use is OnPreserialization() if you're the owner, and OnDeserialization () if you're the receiver. Only the owner ever runs code in OnPreserialization

#

So it'll go something like this:

#
  1. Owner updates sync variables inside OnPreserialization
#
  1. It is determined that ownership needs to change. Anyone can do that using SetOwner ().
#
  1. After set owner is called, there will be a delay until ownership changes. But as soon as it does, your new owner can run OnPreserialization code.

How are you trying to sort the strings? Alphabetically, or something similarly easily quantifiable?

Certain static array methods were just added in the last patch, so there's hope that Sort will be coming soon™️
In the meantime, however, we need to implement the algorithms on our own.

"For now the pattern you want to use is OnPreserialization() if you're the owner, and OnDeserialization () if you're the receiver. Only the owner ever runs code in OnPreserialization"

I've read the player will never call those functions if they're the only one in the instance though. So to save myself headaches, when I need to update something that checks the state of a synced variable, I just place that in an Update node. Not even sure how to work around that if it is actually the case no serialization happens if there's no one else in an instance with you, unless I double up all the code I'd have in events and call it separately for the owner at the same time as they're sending the event, which is not ideal or a good way to keep inconsistencies from creeping into the code as you change it.

Ah here's the post:
https://docs.vrchat.com/v2021.1.4/docs/networking

"You need to have two or more Players in a world to trigger these events, and at least one Synced Variable on the UdonBehaviour where you want them to fire"

There are three ways you can synchronize data and events in your world: 1. Variable Use this when you have a value that you want to synchronize across all players in your world. You will update the value on one player who 'owns' the object with the variable, and listen for the updates on all other ...

cunning mist
#

A lot of stuff in U# that isn't in graph is fancy workarounds and it's hilarious. Like, you can pass variables in non-networked functions, but what is actually happening is there's a variable on the target script that gets set just prior to the event being called and then it reads that.

Is it still not possible to toggle IsKinematic in Udon? I know I was told back in October it wouldn't work when I wanted some pickups to stay in place until picked up, like an axe I had embedded in a tree.

#

I now have some floppies in a disk caddy but I'm running into some performance issues in my world and I'd like to set them all to the player layer so they don't collide with one another, but if I do that then they'll all just flop over and be inside one another inside the disk caddy which will look bad. So my options as far as I can tell are to throw some invisible colliders in there to try to prop them up, or toggle kinematic, or leave them on the pickup layer.

VRCPlayerApi.get Trackingdata or something like that. You can choose Head, Right Hand, or Left Hand from a drop down menu on the node if you're using graph

I'm trying to figure out how to make a jump pad behave in a way where it applies velocity to a player and pushes them away, easy enough to do with playerVelocity = velocityToApply * jumpPad.upVector, this handles the jump pad being rotated so it just pushes away

#

However what I can't figure out to do since i'm a smooth brain when it comes to vectors and math

#

I want to reflect the player velocity if they're moving faster than velocityToApply instead of overwriting it

#

I found Vector3.Reflect(velocity, jumpPadUpVector) that works but I want it to essentially have a minimum that if you're moving slower it would just push you with velocityToApply

#

I can't figure out how to check the velocity and replace it if it's slower

#

velocityToApply is just a float

#

In summary: if you're moving slow, push with preset force, if you're moving fast, push away with same force you're moving but away

fiery yoke
#

@dull stream Thats quite a bit of linear algebra :P
So you have a jump pad with a collider? and as soon as you touch that collider you want the player to be acceled with a minimum force when they are not moving fast "towards" the pad, but bounce off if they do?

dull stream
#

Exactly

#

It's easy to do either thing separately

fiery yoke
#

Well one key part is knowing how to get how "similar" two vectors are. This is done with the Dot Product

#

For normalized/unit vectors, the Dot product is 1 if the vectors are equal. 0 if they are orthogonal. And -1 if they are opposite

#

This is useful when you compare the current players velocity with the up vector of the pad

dull stream
#

I suspected I needed to do the dot product or cross product but it confused the heck out of me in class

#

So I could construct a push vector with velocityToApply * jumpPad.upVector, then grab playerVelocity

#

But how do unit vectors play into this, since these are not

#

Wouldn't comparing unit vectors just show direction

In theory, is there any way to hide all players’ name tags in a world so you could like make a custom name tag system or anything?

#

I can imagine making a shader that only shows things behind the object, then sticking a sphere above a person’s head with the shader so looking at the person’s name tag would only show what’s behind the name tag

#

Basically a programmed version of how many people envision a real-life invisibility cloak would work

#

How long we gonna be waiting for synced variables to actually be functional 🤔

dapper lion
#

@fading cipher there is like a shader that i think covers up any layer like the nameplate which you can then attach it to a head tracking set up that keeps a mesh around the nametag

fading cipher
#

@dapper lion Cue spongebob I need it

dapper lion

i dont have such a thing. i think i have the shader and a head tracking thing you can kind of set up, but itd be weird to set up

I was still running the profiler in Unity the other day when I tried to upload my world and Unity locked up, but not before printing out a message about compressing profiler data or something, and I was wondering... What happens if I have the profiler recording when I upload? I assume it doesn't like, enable logging in VRChat or something... But I also had an issue where people were getting poor framerate in my world the day before yesterday, and today with others it seemed fine, so I'm wondering if like, some data was being logged and causing a slowdown, or what, cause prior tests to that one people were getting good framerates.

how would I play an animation while the player's avatar is in a station, for example a dance animation? I kind of got it working but only the lower half dances, so how would i get tracking to disable while in a station so the animation plays?

How fast is Udon? Like, not networking wise. I've seen stats for that that put it at a 56K modem for speed. I mean how fast does it run the code? Is it really slow? Is it almost as fast as actual scripting would be? I believe it runs on a virtual machine, so maybe it's 1/2 as fast or 1/10th as fast? I don't actually know how much overhead a virtual machine creates and if that's handled by the CPU to make it fast, or if Udon is even that kind of virtual machine. My real question is whether it would be feasible to write an emulator within Udon. I doubt it, and I have no intention of doing it, but I'm curious to know because folks keep asking about it because I just made a world which displays videos of C=64 games on the screen. 😄

quartz meadow
#

that being said, you can do what I did, code your work in a shader, and use udon as a wrapper to get numbers in and out

#

its a pain in the ass, but far faster for complex tasks

#

also, anyone have any word on what the networking patch will bring? Can we finally spawn in items with scripts? Prefabs?

glossy sky
jaunty schooner
#

Try changing one of the transform parameters to 0 and back. There's a bug either with Unity or VRChat's scripts and sometimes, at least with prefabs, that will happen and doing what I said tricks Unity into saving the data you input.

#

However that issue doesn't happen on play, it happens if you just click another object and go back to it. Which play would also do perhaps, but its possible your issue is something else entirely?

glossy sky
#

That's what I was thinking but I'm simply playing the scene and it'd zero everything out.

Just plug the playerapi from the event into the instance of the teleportto

There are a couple ways you can do this. If you're trying to make a certain object never collide with players, then make a new Unity layer that doesn't collide with Player or LocalPlayer and put it there.
If you're trying to make it not collide with players at certain times, you can toggle IsTrigger on the object's colliders through Udon, as long as the objects themselves don't have OnPlayerTriggerEnter in their Udon components, nothing will happen while they're in that state.

mortal star

I'll probably do that, thanks @twilit hawk (I want to disable player collision when player grabs a bar so he can lift thenself through the object instead of being locked on it)

fiery yoke

Yeah I dont think you can dispatch Compute Shaders or use ComputeBuffers. However you can allocate the memory for a ComputeBuffer object and construct it outside of Udon (serializing it into the asset) and load that at runtime. Just cant do anything with it

quartz meadow

#

So, Udon is slower than c# as is the entire node graph system at which point unity doesnt care what node system you use, the conversion time is too high to make nodes practical and the calculation time are increased if you combine node and C#. Hiding functionality inside a shader can be viewed as malicious and why take the extra steps to hide code if you have access to U# which is not a node and not taxing on the calculation times. Take what you want from that, I'm just suggesting using the appropriate tool for the job.

dusk lance
#

Udon graph and Udonsharp both compile down to udon assembly. They have the same runtime.

shaders cant access system resources, wouldnt be a problem security wise

quartz meadow
#

I mean I guess you could make a map with a shader that causes a game crash at worst

#

I don't know why you would

#

but thats the worst you could do

#

there are other considerations when working with shader code

#
  1. shaders are meant for parallel processing, conditional statements completely wreck performance
#
  1. getting data in and out of a shader comes with a penalty
oak trail
#

Theoretically the worst thing you could do with a shader is cause the graphics driver to crash, which in turn crashes the game, but can also crash the entire system if severe enough.

quartz meadow
#

so Ideally, you will prep some data in udon, through it ina shader to process, and pull it out

polar sail
#

does U# expose any additional functions that the normal Udon doesn't allow for?

#

more specifically functions that take input parameters

dapper lion
#

@polar sail it has "work arounds". i never exposes anything other than real udon. thatd be weird and kind of scary if it did

polar sail
#

i suppose

#

perhaps my dreams of being able to generate audio are still too far

#

but might be worth a shot regardless

dapper lion
#

technically they added like 3 extra things on midi and exposed more USR or whatever its called now, so id assume you can do whatever at this point except sound fonts

polar sail
#

well i can't pull the time from the DSP

#

not that that's a neccessity, but i also have to assume sample rates, which might be crashy

dapper lion
#

what kind of crazy bitrate we trying to get here?

polar sail
#

native

#

could cause stutter if two frames return the same rounded time from Time.time compared to DSP

#

but also maybe not? idk, i have to try, i have the code working but nothing is calling onAudioFilterRead()

dapper lion
#

id be very conserned if itd do that

scarlet lake
#

So, @polar sail what i do is write the data and buffer it

    public void WriteSawWave()
    {

        float[] samples = new float[44000];
        for (int i = 0; i < samples.Length; i++)
            samples[i] = Mathf.Repeat(i * frequency / sampleFreq, 1) * 2f - 1f;

        AudioClip ac = AudioClip.Create("SAW", samples.Length, 1, sampleFreq, false);
        ac.SetData(samples, 0);
        targetAudioSource.clip = ac;
        targetAudioSource.Play();
    }
#

For example, this writes a saw wave

polar sail
#

so you made your own sample buffer i see

scarlet lake
#

Yes

polar sail
#

then you're using setdata to put that float array into the audio clip?

scarlet lake
#

Yup!

polar sail
#

that's awesome! thank you so much, not very used to working in an environment like this, it's quite restrictive not being able to use delegates

scarlet lake
#

Yeah sadly

polar sail
#

are you using time.time to delay the audio outputs or just swapping from one sample to the next instantaneously?

scarlet lake
polar sail
#

upvoted ^^

#

will be nice to be able to have some fancy generators to play with if they allow writing to the stream natively

#

however this should be solution enough for now, i think!

#

@scarlet lake do you think it's safer to assume a sample rate of 44100 khz or 48000khz?

#

my hardware is set to 48000 but i am on desktop so i don't have to worry about it as much

scarlet lake
#

441

polar sail
#

alrighty then

scarlet lake
#

Because, its mostly what people use as their default samplerate

polar sail
#

yeah that makes sense

#

mine's usually set higher than 48000 but i have to lower it for games, so i suppose that makes sense

polar sail

hmm, the audio isn't spatialized

Is it possible to use the OnPlayerLeft and OnPlayerJoin events to update a list of the players? For some reason when a player has left, the OnPlayerLeft event seems to be called before the PlayerApi array has updated accordingly.

sand delta
#

is there any method to trigger haptics without pickup?

paper plinth
stark adder
mighty fjord
#

So what should I do about the OnPlayerLeft event being called before the list has updated?

#

Should I just add some form of timer or delay to the event?

stark adder
#

No best thing to do is make an array of players with length of max players there will ever be in your world (or just set length to 80 which is maximum players in world overall) And then in OnPlayerJoin add the just joined played into that array on the first null entry and then OnPlayerLeft remove the player that just left from the array

#

Array.IndexOf(PlayerArray, leftPlayer) gets you index of the player that left and just set that index to = null 🙂

mighty fjord
#

Ah, was hoping it would've been easier to set it up by just getting the players instead of adding and removing them from the array manually

grand temple
#

now that isvalid is a thing, it's mostly not necessary to do all that manually. Now you can just do onplayerjoined > getplayers

#

as long as you check isvalid whenever you try to access any of the elements of the array, you're good

stark adder
#

Yea that's kinda true yea

grand temple
#

there are situations where you might want to insert them manually, like if you need a sorted list. But for general purposes, getplayers will work just fine

stark adder
#

Also not sure what you're using that array for but you should know that the order of the players in GetPlayers is pretty much random.. Each players gets different order for some unknown reason -_-

mighty fjord
#

This is my current setup, and I send an event to UpdateList whenever a player joins or leaves. However, the issue is that when the OnPlayerLeft event is called the list of players in the world hasn't had time to update accordingly.

unknown.png
grand temple
#

that code there is completely unnecessary, you're just running getplayers over and over for however many players there are. It's just gonna give you the same thing every time

mighty fjord
#

Right

#

Even if I did fix that, wouldn't I still end up with the same issue in the end?

grand temple
#

if you try to print out the player list onplayerleft, then yes it will include the player that just left. But any time after that, if you do isvalid you will only capture the people who are valid so it doesn't matter if they're technically still in the array

mighty fjord
#

So I'd have to call some form of event afterwards to make sure it's completely up to date?

grand temple
#

or when you're printing out the list of players onplayerleft, just check if not equal to the player that left

mighty fjord
#

Yeah, could do that too

#

So should I store the GetPlayers array before I go into the loop and then loop over it btw?

grand temple
#

yes exactly

#

you only need to do getplayers once

mighty fjord

Thanks for the feedback 👍

I think I've asked this before but it's peaking my interest again. What would be the best way to build a programmable screen. E.g: in the Udon behaviour setting the colour for each individual pixel and having it refresh at around 24fps? 🤔

The best I could do before was a RendererTexture/Texture2D ( can't remember it was ages ago) that could update indivisual pixels but the game would chug for like 3 seconds for each frame

#

The other thing i'd like to do is just fake a screen, like apply a pixelated shader over the top of everything so it looks like a fake screen. But that doesn't seem as cool than actually emulating the device 😛

@fading helm I dont think thats possible without heavy trickery

fading helm
#

in a sense, more like mario 3D where you can jump from small planets/platforms to the next and walk around them 😉 but i loved the old avp game, i will keep this in mind 😄

#

my idea atm is to bind an invisible object to the player (like a vehicle you have to get into) and let it face a direction and then move the player just with it, but that seems sooo inconvinient

fiery yoke
#

This is not supported in VR because rotating the player causes a lot of simulation sickness for a lot of people.

#

You can do it with some trickery, but youre not supposed to hence it is not supported.

stoic mountain
#

I dont think you'll have the kind of control you want on the player gameobject, its pretty limited. Im afraid the vehicle approach wont work either as that restricts body movement ... or maybe you could do something based on bones position to detect that movement ? Anyways it sounds really tricky to do with the current tools available

Idk where to post..

WTF is this

fading helm

Yeah you would think that that argumentation makes sense. But I guess it doesnt. The Oculus VR SDK does not support rotating the playspace. So I guess its really a limitation of VR SDKs. Its something thats...mathematically weird. Causes confusion, bugs and other problems.

Could be supported at some point. But I doubt it.

fiery yoke

Restarting should help

stoic mountain
#

You dont really need to rotate the player space tough. You get the head & devices positions from it and then you can apply that relative to whatever you want.

#

But snap rotating could make @fading helm project work tough - i mean motion sickness-wise. If you could point at a wall and "teleport move" there without continuous rotation, that would be fine

fiery yoke
#

Yeah. But you cant do it in VRChat, because of either VRChat (imposed or not) limitations or Unity/VR SDKs limitations.

#

At least not "easily"

stoic mountain

Yeah Im affraid that's the bottom line ... doing this in the current state of vrc is just gonna be very tricky, or maybe simply not possible

And it doesn't work up and down, for example like an elevator, you need to turn gravity off on the player before you move him around or he will jitter

But if you want him to be able to be controlled normally, you can't go up and down.

i have some doors that open if you interact with the doorhandle, and i'd like to make it so that if one person opens the door, it opens for al other players too (and if someone closes a door, that it closes for all other players too)

i tried checking the "synchronise position" box, but this disables the animations for some reason.
does anyone know how to go about this?
it would be cool to have global object toggles too, but that's less important.

paper plinth
#

you must use ondeserialization and syncronize animations that wayI think you can get around it just by not using animations and apply your transform directly to the object but I've only been in here for 3 months

#

something like RotateAround I think isn't an animation and just updates the position but I am not there yet

pallid remnant
#

ooh

#

i see, so what youre saying is ditch the animator?

paper plinth
#

that's one way

#

the other way is to learn how to use ondeserialization which will be a relevant skill for less than a month when the networking update comes out

#

I'm waiting for that and jacking with other stuff in the meantime

#

There is always multiple ways to make something work. The easiest for you is to do SendCustomNetworkEvent which tells everyone to open the door, when you interact with it.

paper plinth
#

a most elegant solution

pallid remnant
#

how should i go about incorperating this module in the code?

Screenshot_2021-03-16_133343.jpg
fiery yoke
#

First of all thats the wrong node. You want "SendCustomNetworkEvent.
You replace the Interact with a Custom Event and call it something like "OpenDoor" then you connect the Interact node to the SendCustomNetworkEvent and enter the name you gave it

pallid remnant
#

oh shoot you're right

#

like this?

Screenshot_2021-03-16_134035.jpg
fiery yoke
#

No

#

Search for "Custom"

pallid remnant
#

okay so instead of the interact i want the custom event

#

and then in the same graph i put an interact connected to a sendcustomnetworkevent that has the same name as the custom event that replaced the interact

Yes exactly

Can I send a custom network event when an animation finishes playing to restart the animation and have it synchronize for everyone? I have cars that drive around the block, an animation on a loop.

@minor pine This is the wrong channel to ask something like this. Try #vrchat-general-2. But you want to use some other VR Overlay software like XSOverlay, OVRToolkit or something like those

fiery yoke
#

Yes that is normal. You cannot use the SteamVR desktop view while in-game

Because they are probably using the Oculus Overlay which is different

Oculus has an in-built overlay that you can use. If you dont want to use that or you dont have Oculus then you need a seperate software.

So i'm getting into writing shaders, would using Udon be the correct way to apply a shader to the users view?

#

^ an example being a world that has a black and white filter you can enable

cunning mist
#

You would likely have it be a screenspace shader, and use Udon to hold the sphere or whatever you are projecting it on against the user's view.
While I'm sure greyscale was just an example and you can do lots of other things, greyscale itself can actually be done really easily by animating post processing, just so you know!

#

Is there a vrc unity layer that players collide with, but pickups don't?

void ridge
visual grotto
#

rad, thanks

void ridge
#

Collision layers are a pain to work with. Your situation is a good example; it looks like MirrorReflection would do what you want, but generally that might be a bad idea.

#

Any renderer on MirrorReflection will not be rendered to the player, except in a mirror. You can get around this by separating your collider to a different GameObject in some parent-child relationship with your renderer, and put the collider on MirrorReflection while the renderer is on Default or some more appropriate layer.

visual grotto
#

Yeah that should be fine, I want pickups to fall through a certain floor that players can walk on

#

just putting the collider on mirrorreflection and sticking it on a separate gameobject should work

void ridge
#

You also have the option of adding a completely new layer and defining the collision settings for it. Caution there is that I've had a little bit of weirdness with those layers as far as colliding with players is concerned.

void ridge
#

Leave your floor as Default, and don't touch it

#

Instead, change your pickups to the PickupNoEnvironment layer

visual grotto
#

Well, there are other items I do want pickups to collide with

void ridge
#

Unless you need those pickups to collide with some other layer at some other time 😛

#

yep

stoic mountain
#

how would you transmit a SetParent() through network ?
When a object of type A collides with an object of type B, I want A to stick to B (kinematic true, setparent) so I can move the host object B by script and A follows along.

Now I cant really do that detection client side as object A is a rigidbody, and sync is not guaranteed (or rather, its guaranteed not to be in sync). So I need master player to detect the collision, and tell the other players it happened. But I cant transmit values through SendCustomNetworkEvent(), so im not sure how to proceed ...

#

Or maybe transforms parent are synced along the position when UdonBehavior "sync position" is set to true ?

willow tartan
#

I believe object sync uses world position but you'll probably have weird jittery behaviour if the parents are different and you're moving the parents around

#

You can keep some internal list of potential parents and sync the index into that list

stoic mountain
willow tartan
#

With the new sync model you could probably add a child object in manual sync mode to send over the parent identifier. If you don't want to maintain a list of candidates, sending an object path is another (slower) option

stoic mountain
#

"manual sync mode" ?

I have a weird bug with a simple boolean in an UdonSharpBehaviour.
The boolean is name inContainer. If checked all codes and the only place it can be changed is through a method that logs when it get changed for debug purpose.
I can see the value change and get set to true when the objects is put inside the container, but at some point apparently that boolean switches back to false without that method being called.
I have no idea whats happening there. Testing through CyanEmu, one player.

pallid mango
#

I’m surprised it compiled

stoic mountain
#

I suppose CyanEmu doesnt really care as its in editor

grand temple
#

well if you use cyanemu then it's all running in editor, completely bypassing udon

#

cyanemu itself is made of monobehaviours

stoic mountain
#

I cant be mad at CyanEmu tough, its just too helpful

pallid mango

I think CyanEmu has a setting to strip out stuff vrchat would delete, but not sure if that includes mono behaviors

stoic mountain
#

to be fair there could be some warning somewhere in the console logs, but I have too much debug stuff there

CyanEmu doesn't have anything to check for scripts. It just implements some api callbacks which then can be called from anything.

@brave meadow i have a udonsharp script that might assist you

normal swallow
#

Hello! I suppose I might just be missing one small thing but I have a udon script with a trigger event, but the trigger will only activate once? Is there something i have to check to make it repeat?

grand temple
#

either you're using a trigger that only happens once or the udonbehaviour is crashing

worldly tapir
#

Hey, can't find it anywhere, what's Udon's version of the switch statement? Got 128 cases.
Or should I just binary search for the input with if statements? Would take 7 steps though, kinda slow compared to switch's lookup tables

normal swallow
#

if the behavior is crashing, is that something on my end I can fix (in unity)?
as for the event i have,
its OnTriggerEnter an area, it destroy the object. and then makes it appear at another location.
when i try to take the object back in that area it just does nothing.
I tried setting up another area with a different udonbehavior but after one of them is activated they dont work,
Maybe its not detecting my item anymore?

#

Also, just as a general practice question should i cram as much as possible into one behavior or should I add multiple component where they all do their little things. ( if that even change anything)

grand temple
#

there are several reasons why it might crash. The first is that when you do ontriggerenter, it's possible that it will detect protected objects. Protected objects are things like the players or the UI that exist in the world but udon is not allowed to access. When this happens, if you try to do anything with them, the udonbehaviour will crash.

The fix for this is to use Utilities.IsValid to check if it is a valid object before doing anything with it

#

and the second possibility is that if you try to destroy something, it no longer exists. If your code tries to destroy it again, then it's going to crash the udonbehaviour because you can't destroy something that's already gone.

The fix for this is the same, use IsValid before doing anything with anything that you're not 100% sure is valid already

normal swallow
#

Is this only on a recent version of Udon? I dont think i have that option, This world i have is using an older version for sure.

grand temple
#

yeah, isvalid is pretty new

normal swallow
#

ah, look like im gonna have to do an update..

grand temple
#

if you're using udonsharp you can also just do != null but it's a bit trickier in graphs, takes like 4 nodes to do the same thing. Also only works on protected objects, not destroyed objects

normal swallow
#

the behavior i have does have Object Destroy and then it use Instantiate to put it back. Would it still consider the object destroyed?

#

If I can simply update to the latest ill try that and see if doesnt break any of the other working behavior and I should be good? If it does break stuff well ill have to decide which problem i want to spend time on 😆

grand temple
#

the destroyed object itself doesn't matter, what matters is the reference to that object. If you say destroy object then set the reference to that object as null, then you can easily just do if (object != null) and you're good.

normal swallow
#

Thanks, That gives me a couple thing to try, Ill run some test on those tomorrow and see how it goes.

UI Question. So I'm fairly certain I know how to call a OnValueChanged event for a slider on a canvas, using SendCustomEvent, but uh, the slider itself doesn't appear to be intractable. I've only placed the slider, is there any other component I need to add?

grand temple
#

you need to add vrc uishape to the canvas and you need to set the canvas and all of it's children to the default layer

vernal maple
#

Aha. I saw the VRC uishape component, but was trying to add it to the slider. Thanks so much. 💜

#

Works perfectly! And fortunately everything is working in the build and test as well.

acoustic delta
worldly tapir
#

Oh no. Oh no.

#

Guess it's binary search time then, don't want to run 128 checks for something that may happen twenty times a sec. Thanks for the info

grand temple
#

I wonder if it would more efficient to do something like sendcustomevent("Event" + integer);. On the surface that looks dumb because udon on the backend would have to do string comparisons, but udon is way slower than C# so offloading something like that to the backend might actually have an impact

#

sounds like something that needs to be benchmarked

worldly tapir
#

I'll do anything if it works as a workaround around a 128 element if else chain. I may not be a professional, but also try not to be a complete yandev codewise

grand temple
#

does it really need to be 128 unique code execution paths? Could you have a single execution path that accesses various 128 length arrays?

worldly tapir
#

I'm trying that at the moment. I'm slightly varying the code and values for each, but I might be able to calculate these variables from the int I'd have switched on.

#

Though with that method it'd be really helpful to be able to define methods/macros or something, is that possible in udon?

normal lichen
#

how do i fix this?

unknown.png
grand temple
worldly tapir
#

Not really, more like functions and macros in UE4.
e.g. making a custom "multiply by two and convert to string" node as an admittedly stupid example

#

That I can reuse without having dozens of copy/pasted nodes

grand temple
#

I would not be surprised if visual studio supported something like that. As long as it outputs the final expanded code there's no reason why udonsharp wouldn't accept it just fine

#

but udon graphs themselves, definitely not

worldly tapir
#

I started with udon two days ago, only using graphs so far, but I'm slowly beginning to see why most of my friends complain about it so much xd

#

Thanks for helping tho ^^

grand temple
#

oh yeah with the stuff you're talking about already I'm sure you would be much better off with udonsharp

#

udon doesn't run on the graphs directly, it runs on udon assembly. Udon assembly can be made from many different sources, including graphs and also normal C# code, through the use of udonsharp

vernal maple
#

I have a crazy question now about UI. Is it possible to attach a Canvas to the camera when a player is in VR?

grand temple
#

yes, that's exactly what uishape does when it is a camera-space canvas

worldly tapir
#

Well... I do know c#, I've made unity vr games before, but I think I don't know enough about the limitations of udon assembly. E.g. the switch statements. If I did that in udon sharp, not knowing it'd create a demon spawn of a if else chain, I'd have been in for some trouble. Graphs are at least more "honest" about their current limitations it seems ^^

vernal maple
#

Lemme give that a shot

#

Does this look accurate? Or will overlay mode still make things not work?

grand temple
#

not very well, mind you - the canvas will change based on the resolution of the headset

#

I'd recommend just making a world canvas and have it follow in front of the player tbh, it would be much more consistent

vernal maple
#

That does certainly make sense. I'm hoping just anchoring it to the bottom left of the player's camera will make things work.

#

It'll just be join/leave messages, your turn, etc messages.

#

#

We can't yet send custom network events with arguments, can we? I just wanna broadcast a client's local value (score) to everyone else, along with that client's ID. I can manage the players and scores on the receiving end. It seems messy to make a whole list of unique synced variables to cover every possible player in the world. Is there a better way to do it?

grand temple
#

that's correct. If you want to do something like that I would recommend using manual sync in the udon networking beta

#

manual sync is faster than network events, only syncs exactly when you want it to, and will carry all your synced variables in one burst

strange charm
#

it doesn't need to be fast, it just feels like im doing it the wrong way making those synced variables

#

compared to just broadcasting stuff and sorting it on the recieving end

grand temple
#

as it is on live, yeah pretty much. Everything is synced continuously, which means it will sync 5 times per second and it will have very low priority

#

when not in use, manual synced variables have zero network cost so you don't need to worry so much about creating synced variables that will sit there taking up bandwidth most of the time

strange charm
#

will worlds made with the networking beta run on the release client?

grand temple
#

You'll be able to get into the world but if you use any beta features the udonbehaviours will crash

For making grass move, do you have to animate the asset or can you have some udon wind controller?

#

I have a wind controller script, but obviously does not work in VRchat

unborn hornet
#

Might be some sort of shader that manipulates the rendered vectors of the grass...

#

Just speculation on my part tho

dusk lance
#

You can write it in shader. I suggest looking at your script and trying to convert it to Udon

void ridge
#

Meaning to profile it eventually, just not there yet.

#

From what I understand (not a lot), shader is the cheaper way to go for something like that

dusk lance
#

I have written my own simple grass shader and all movement is in shader. Transform never changes.

#

You can use scripts to pass parameters though

#

It would be similar to changing the color on a material, except it isn't a color.

void ridge
#

Oh I see, sounds like a whole other thing I gotta learn about

dusk lance
#

Shaders is it's own complicated coding system, but amplify can help with that.

willow tartan
#

having a handful of update scripts isn't the end of the world, as long as you don't do anything too complex in them. but I agree that ideally you'd want to do this in shader

worldly tapir
#

quick question, not @ pc rn, but is int32 to bool safe in Udon or should i favor an if statement?

grand temple
#

In what language would that ever be a direct conversion?

c doesn't have a bool type really. Anything that is not null or 0 will evaluate to true.

worldly tapir

Just checked, both int to bool and bool to int seem safe

#

Oh, better question: does the variable to be changed need to be public?

fiery yoke

no

Its confusing. But essentially public just means that you can edit it in the inspector. Other than that there is no private or public with variables (in Udon)
It also has something to do with whether or not they are serialized or not, but that only really matters with custom editors (besides the inspector editing).

Hello, I need help. I have created a simple toggle udon code and Idk how to make it global. It works locally

does anyone know if there is a way to make "ontriggerenter" only react to specific trigger instances?

i have this beer glass i want to fill on collision with the tap, but it also works with every other trigger that exists in the world.

so, if i take the glass through a door with a trigger on it i use to control audio, the glass still fills because that also counts as a trigger.

If the name of the object is beer glass

Fill it up

Are you looking for gameobject.setactive?

hmm?

# misty berry hmm?

You usually have to search for the class first (in this case GameObject) and once you're in the class, search for the specific node

#

You should also check to see if you're accidentally searching on a selected node, which limits the search to nodes that can connect to whatever you have highlighted

#

Searching is a little fiddly sometimes but once you get used to the shortcuts it's pretty good

you might be using 1 that is designed for local usage

Trying to wrap my head around Udon & the graph editor, Would this work for creating a mirror that activates based on distance?
Or am I being naive and stupid :p, It's on a object with a simple box collider

turn on the search on noodle drop

you need a string contains

not equals anything

ooh i see

looks like it

#

uhhh wait I'm sorry i didn't look at it closely

#

you have to come out with collider other, get the gameobject from that and get string contains from there

#

here I have unity open now lol

#

so much easier to do graph just by doing it
these u# guys can just tell you

paper plinth
#

what I do is put them all in group, and then instead of get name, I get parent and then get name, then I can just reference the entire group wherever I go

pallid remnant
#

thats a way better idea

paper plinth
#

like put them all under the same gameobject and then just refer to that one

pallid remnant

yeah collider get name gets the name of the other collider

the name of the object with the collider on it

if you want its parent, do this:

if you use the 0.3.0 or 0.2.8ish versions, they auto play if you use the default playlist feature

@runic mauve theres an updated version been working on that uses a seperated playlist feature instead

With Playable Layer Parameters that can be read by Animation Controllers, is the Avatar Descriptor Viewball x/y/z value , or specific (hip) bone height, or any type of variable that is relevant to the Unity 1 unit = 1 meter scale?

Asking because I'm looking at Anim Controllers for Stations and that's a World thing, also asked in the Avatar chats.

pastel kite
# pastel kite With Playable Layer Parameters that can be read by Animation Controllers, is the...

I'm looking for the Unity scale units of [specifically the hips but I figure the avatar descriptor visionball would be more apparent]. A way to figure out if a player's avatar is a 0.4 meter tall person or a 2.0 meter tall person is helpful so that I can design a custom Animation Controller to put on a chair/Station that positions the player differently depending on their height. When someone makes their own avatar, I'm sure they're not taking the time to go "Oh I'm making this avatar to be a twelve foot person" and custom make an animation pose so that they fit in with the "common" (I wish I could say standardized) 0.3m or so height that most chair/Station geometry are built at.

A small person will clip into the chair. A larger person will have their legs through the floor and knees way out past the seat edge. Being able to design a couple 'helper' animations like how the Crouch and Prone locomotion controllers work is how some kind of Unityworld-scale Parameter will let me position someone to fit where they sit.

Don't know, but maybe try experimenting with skeletonbone.getscale or humanbone.getscale?

#

"A way to figure out if a player's avatar is a 0.4 meter tall person or a 2.0 meter tall person" also possible by raycasting downwards from a fixed height, though a 1m person with a 40cm hat willl appear as 1.4m

I have trouble with a gameObject.GetComponentInChildren<SomeUdonSharpBehaviour>() that apparently stopped working recently
anyone knows of recent changes or bugs that could cause this ?

I have a floor that rises and need the player to rise with it.
Using localPlayer.TeleportTo(floor.transform) every update statement has the player kicked for "Unusual Client Behavior."
Is there a way to have the player follow the transform of an object every update statement without being kicked?

worldly tapir
#

Just a hunch, but maybe use a chair (VRC_Station) and move that? Might be possible, don't think e.g. temporarily parenting the player to a gameObject by other means is possible yet

dapper lion
#

i think theres a way that checks avatar height that can then be used to update theplayer position at a slower rate but im not 100% on that. but eventually therell be an easy animator trick or something thatll reveal itself

worldly tapir

Huh... At some point in my script, every conversion returns null. I set up an int and need to convert it to a float. When I put it at the start of my code, it works. If it's a few nodes in it returns null. Tried to bypass it by going the (very stupid) route of converting int to string and parsing a float from the string, but the tostring node suffers from the same problem.

Does anyone know why this could happen? If not I'll investigate further tomorrow, it's nearly 8am and I should probably sleep a little xd

haven't tried that yet but may look into that.

Any way of telling whether an object is held by the right hand, or whether the right hand is holding an object?

#

Never mind, found it: udonScript.PICKUP_COMPONENT.currentHand == VRC_Pickup.PickupHand.Right;

paper plinth
#

You can do that every frame without pissing it off

chilly aspen
#

That's pretty much what I'm doing atm, but observed one frame of a hundred thousand will remove the player from the world.

#

I've set it up so it only teleports the player every other frame, hopefully that reduces the likelihood.

Doing some thinking / learning. Would it be worth creating an empty gameObject that is the master object used for syncing variables & have all other udon scripts have a public gameObject that can be assigned to the master so they can read the data?

Be careful, though: don't take the boolean value of that Unary Negation, or else you'll end up with one active when the other is inactive

is there something specific to do for a pickup to stay kinematic (not falling) ? I tell my pickups to become kinematic in some cases but they seem to just stop for a frame and resume being physics right after that
