udon-general

[hasty kraken]

So.. I get this issue when I import UdonSharp, clueless. Any help would be wonderful!

[grand temple]

Something broke when importing. Best to just clean everything and try again. Follow these steps:

Close unity
Navigate to the unity project in your windows explorer
Delete all folders in the project that have anything to do with VRCSDK or UdonSharp
Open unity
Import VRCSDK
Import UdonSharp

[hasty kraken]

I tried starting fresh with a new project, importing the VRCSDK first then UdonSharp, but as soon as UdonSharp is added, then I get the error.

[grand temple]

Do you have unity 2018.4.20f1 and the latest VRCSDK and latest Udonsharp?

[hasty kraken]

Yea

[serene moat]

make sure you installed the unitypackage from the releases page

[hasty kraken]

Trying that right now.

hey guys, i dunno where to even start with this graph. still having the same problem as earlier, i have a list of materials and i want to change the values based on 2 buttons being clicked (forward/backward) and im wanting to display those materials (not all at once) with the buttons. i looked here https://docs.vrchat.com/docs/networking# to kinda get started with the value being synced, but im stuck. there are so many different nodes, its just, ugh.

is there maybe a list of ALL the nodes somewhere followed by details on what they all do specifically? might help me out a lot. lol

the part im stuck on is determining which material is currently being displayed, and reacting to a button push accordingly.

[floral dove]

there are Thousands of nodes! But you can find info about many of them in your project under Assets/Udon/ReferenceDocs/index.html - open that up in a web browser. You can get more info about any node by clicking on the question-mark in the upper-right corner of most nodes. In your case, you want to make a synced variable that you can use as an index to your array - it will hook up to the slot that currently has a '0' in it on your Material[].Get node

It may also help to learn about how Arrays work - here's one from the inimitable Daniel Schiff: https://www.youtube.com/watch?v=NptnmWvkbTw

[ancient spindle]

after some googling, i came across vowgan's little material swap demo here https://github.com/Vowgan/MaterialSwapper and this is essentially what i am looking for, however making an interact to send a custom network event doesn't seem to swap the materials even when the sender/receiver both identify under the same event name.

[ancient spindle]

ill give it a look

[ancient spindle]

does the custom network event have to be triggered on the same gameobject as the receiver for it to work?

[rough beacon]

how long this file been missing? it like that on my other world and it seem to work right. i was looking for bug problem that seem to be hidden.

ok, that out of way, how can i find a bug problem that upload world but stop player from joining the world?

[ancient spindle]

are you able to run a test instance within unity? (Build & Test) ive had a problem like that before and it was because of an animator/collider issue lagging people out of the instance.

[rough beacon]

i can run test without any problem. but when i upload to world. it push player to home world

i think i found my bug. some odd reason my cam img end up in skybox material. but only 1 way to be sure if that the problem

[rough beacon]

fix.

[sleek grotto]

Can you give an example (for Vimeo)?

[toxic arch]

Does anyone know how to change your avatar's size?

[floral dove]

I don't have Vimeo Pro to get a working example, but you need a direct link as they describe here: https://vimeo.zendesk.com/hc/en-us/articles/224823567-Direct-links-to-video-files

[crude escarp]

Hey, I hope someone can help me on this one. How do you react to the main menu opening? I made a Udon Sharp script that moves my world menu in front of me on double jump. But I'd rather have it appearing when I open the menu like the VKet worlds do. I just really can't figure out how.

[fickle stirrup]

@crude escarp since new vrc's InputSystem does not have an action subscription for the controllers menu button, you need to use if (Input.GetButtonUp("CodeName")) { } inside Update function, you can check their codes here https://docs.google.com/spreadsheets/d/1_iF0NjJniTnQn-knCjb5nLh6rlLfW_QKM19wtSW_S9w/edit#gid=1150012376 so for the left controller Oculus_CrossPlatform_Button4 and for the right Oculus_CrossPlatform_Button2
(I think this is how it's done)

[floral dove]

FYI we block most inputs while the VRChat menu is open so this isn't a great way to go. We'll have more info on a better way to do this in the dev stream next Tuesday.

[crude escarp]

@fickle stirrup Thanks for the quick response. That explains why I can't find the event to do it. But on update sounds rather costly as it is run every frame if I am correct. Will think about it. And thanks for the link!
@floral dove Sounds reasonable. Looking forward to Tuesday then 👍

[fiery yoke]

Its all relative. If you do a single instruction in Update, nobody will ever notice that. But if you do that a few hundred times then obviously it accumulates.
Its mostly about how much do you do it, and could you avoid it. If you cant avoid it then there is no harm (unless it completely cripples the framerate lol)

[crude escarp]

It should only be two ifs and sending an event if the button is pressed down I guess. Shouldn't be too bad but I'd still like to avoid it if there is a better method. I'll wait for the stream and decide what to do then.
Also I don't mind the menu blocking inputs. I just want an unintrusive way to summon it. I'm used to having to open the menu and closing it again to use the VKet menu. It's not too bad and doesn't interfere with other actions like double jump.

[copper crater]

hi, i know this was answered before, but the solutions arent really working for me. i have a group of objects and a button that i want to reset all of the objects positions

its a chess set, so i want it to not be local

i did this

i'm really new to udon, so please answer in a way that's a bit easier to understand 😅

[void ridge]

It looks like this graph will work for one chess piece

But you need to tell every chess piece to return to its starting point. There are probably a few ways to do that

I'd make a single script, a lot like what you have, that runs on each chess piece, and then one central button with an array of all those chess piece UdonBehaviours

then on button press go through all the elements of the array and send a custom event which then sent a custom network event to the Owner, who would tell the object to reset to start position

I wouldn't do what you're doing with SetOwner--I don't have a great reason other than, I don't trust networking that much

[copper crater]

uhhh what

im sorry i really dont know how to make that

[void ridge]

Yeah, that may sound complicated but I promise it's not bad

You can learn about arrays and executing something for each element in the Udon Example Scene

SendCustomNetworkEvent with the target as Owner is a single concept, but it's part of Udon Networking, which as a whole is tough to understand, but if you focus on that single concept, it's not too hard

You're on the right track, though. Like I said that script is the kind of logic you need for a single chess piece. You just need to execute it over the network for every piece.

[void ridge]

I sketched this together as a starting point for a button. Beware that I could easily have made mistakes in here, because I don't have a quick way to test this.

I really recommend checking out the graphs in the Udon Example Scene to get yourself more comfortable

[copper crater]

thanks

i'll try that

@void ridge i cant connect the get and the chess

this part

oh wait

i realise why now

[void ridge]

Yeah you're using an array of Transforms, which will work, since Transform.GetComponent is another path to getting the UdonBehaviour

But if you do that, you need to Get the right type from an array. You were trying to get a GameObject from a list of Transforms

[copper crater]

yeah, i changed it

no idea where to go from here, trying to figure it out

[void ridge]

This sends an event to the owner of each chess piece. Now on each chess piece, pretend you're the owner, receive that event execution, and use it to reset the piece back to its start position

Also, it looks like you left the target of SendCustomNetworkEvent as "All" rather than "Owner." Better to set that to Owner.

Since the Owner is the only one allowed to update and synchronize the position of their pieces.

[void ridge]

And you should be able to do this with a single Udon Program. Just attach the same one to every piece.

They're all run independently of each other. They follow the same program, but the variables will be independent for each.

[copper crater]

😅

thanks.

i still don't know how to do that but thank you for the explanation

i've spent hours trying to figure this out and it just isn't working so i'll just give up for now

[tribal meadow]

What would the udon graph node equivalent to SetParticlePlaying be? Currently I have a switch that hides and unhides a particle effect but it's really jarring to look at when you turn it off before the sequence is finished... I want a way for it to stop playing the particle effect 'cleanly' and not just forcing it to dissappear

[grand temple]

That would be particlesystem.Play

[tribal meadow]

Thankyou

[sleek grotto]

Thanks a million!

[native rampart]

what are the GetServerTimeInSeconds values based on?

the values that I'm getting come out to only around 21 days worth of seconds...

[grand temple]

I assume it's something like how long the server you're connected to has been running. The exact time doesn't matter. What matters is that it's a number that is synced between everyone.

[native rampart]

for my purposes, it matters if the number will ever roll over back to zero while there are still people in the room

for the record, I was getting the 21 days number on a room that I was just testing locally from Build & Test in Unity

[grand temple]

it's a float, isn't it? So in theory it shouldn't ever roll back. At most it will just lose precision

servers get restarted occasionally so I don't think that's going to be an issue

[native rampart]

just, the fact that a room that has only existed for a few minutes was giving a value that only went back 21 days made me wonder if the value rolled over every so often

anyway, I don't like having to wonder, I'll just use GetNetworkDateTime instead I guess

[grand temple]

because "server" in this case refers to the one server that handles many instances. There isn't a whole server per instance

[native rampart]

so you mean there's a new server that they just installed 21 days ago?

[grand temple]

no, I mean whatever server it's referring to probably got restarted 21 days ago

[native rampart]

ahh, OK, that makes sense too yeah

[grand temple]

there are probably many such servers

[native rampart]

what shader pragma targets are supported on VRchat?

or is it entirely down to individual users' GPUs?

actually I guess that's not an Udon question is it

[grand temple]

Shaders have to work with the Built in render pipeline in forward rendering, you can find documentation here https://docs.unity3d.com/Manual/built-in-render-pipeline.html

[fair terrace]

Has anyone found a normal chess game for a SDK3 Udon world? All I can find is 4d chess...

[dapper lion]

theres a $15 version on booth by ahwkidz (i think im spelling it wrong) but other than that. normal udon chess does not publicly exist yet

[native rampart]

Is there any way to set global shader properties in Udon?

yeah come to think of it, that would risk messing things up for other worlds and avatars, wouldn't it

anyway, per-material works as a workaround

[quick junco]

Hey does anyone know how to fix it not wanting to Build n Test NOR publish?

Nevermind! I found the issue

[sand berry]

hey uh I can't hear any voices

I checked all my settings and stuff and voices are maxed with worlds at 0

[grand temple]

yes that's a known issue with vrchat right now. You have to restart vrchat to get audio back

[sand berry]

can I join friends tho

[grand temple]

however there's also an open beta that fixes one of the causes of this bug, you can switch to that so it won't happen again

yeah of course you can join friends

[sand berry]

kk

ho do I do that

I got this yesterday

[grand temple]

right click on vrchat in steam, go to properties, go to betas, and select open beta

[restive dust]

I must be missing something here because it seems like Input.GetKeyDown() is suddenly not working, in graph and U#. I'm doing it in Update(). Anyone know what's going on?

[grand temple]

maybe the script crashed

[restive dust]

Oh I should have been a bit more clear. My confusion was caused because when I tried a newer version of the SDK, Input.GetKeyDown() wasn't firing. So I was wondering if there was a change that I missed. But I must be doing something wrong. Will carry on trying different stuff. Thanks!

[grand temple]

if something broke during an sdk upgrade, then likely a lot more is broken that just one event. A common example is your log getting filled with hundreds of errors and nothing will work

if it's something like that, then just cleaning up the project outside of unity and reimporting everything from scratch will fix it

[restive dust]

Ok update, restarting the editor fixed it. Somehow that didn't occur to me earlier.

[grand locust]

Very stupid question:
"How i set a Object on [OFF] ?"
I won't start with all my Lights, Mirrors and Players on. I didnt find any Video or a other sort of tut for that.

[restive dust]

The SDK comes with an examples scene (VRChat Examples > UdonExampleScene). Take a look at the Udon graph in MirrorSystem's Udon Behaviour. That shows you how to toggle a gamebject on/off. If you only want to set it off, don't plug anything into GameObject.SetActive()'s value port.

[grand locust]

How to toggle a Object with a "Button" i figured out, thats not the Problem.
But i think the Information:

If you only want to set it off, don't plug anything into GameObject.SetActive()'s value port.
Is that what i searched. I will test it later if it do what i want - but thanks for the information anyways !

[fast prairie]

Is the hand data in GetTrackingData different from GetBonePosition and GetBoneRotation? Having problems with different avatars in the world due to funky bone rotations or something similar

[fiery yoke]

Its the same for remote players. For the local player Tracking data actually gives you the position of the hardware devices (sort of)

[fast prairie]

neat. probably just what I wanted to hear. I'll give it a go thanks

[hushed gazelle]

if I want something in a world to respond to particles on a player's avatar (eg; shoot a target with a gun on an avatar), will OnPlayerParticleCollision do what I want?

[past sand]

Anyone know how to make a world quest compatible and can assist me?

[grand temple]

No, it's the opposite. Onplayerparticlecollision refers to when a particle from the world hits a player. You need normal onparticlecollision. Just make sure to enable "send collision messages" on the particle system

[dawn plover]

Hello! So, I'm trying to make a script and I need to check if the player is in VR or not, so I'm using IsUserInVR at onStart, which I'm guessing is too soon because I always get an inconsistent result, so when I need to check if the user is in VR? Or is it possible to do this on the start? I've seen a node called IsNetworkSettled, but I'm guessing it will work only on events like onUpdate or something that's continuously checking 🤔

[void ridge]

You're correct, it's inconsistent. If I remember right, IsNetworkSettled won't guarantee it.

I don't know of a clean solve for this. I've heard theories about using OnPlayerJoined with Local Player.

I usually just delay the check by 2-5 seconds and hope for the best.

Would love to have a solution I can trust for this.

[hushed gazelle]

@grand temple ta, I wondered if that was the case.

[dawn plover]

Yeah, same, maybe having an event like OnNetworkReady would be nice, like VRCSDK2, so we know when the player is fully loaded, even if I'm pretty sure that maybe you can have the same result with onDeserialization, you just need to make it run once with a boolean check lol

[void ridge]

OnDeserialization will also only fire if you don't own the gameobject, so woulsn't work for first join.

[fiery yoke]

Start. Start runs after the network has settled. (Not after you received all network data, thats a different concept) And it only runs once.

[void ridge]

But Start still fires too early for IsUserInVR

[fiery yoke]

Ahh yeah true. Wonkyness. Guess you can use Late Update with a boolean check as a workaround?

[grand temple]

Sendcustomeventdelayed is a thing now 🤷‍♂️

[fiery yoke]

Right. But sometimes frame "perfect" execution is important.

[grand temple]

You can adjust which update it happens on. Update, late update, fixedupdate. And you can define it by number of frames

[fiery yoke]

Like I mean maybe you need to setup stuff in the same frame as something else, but in a particular oder. But yeah if you dont need that fine control then delayed events should work.

[void ridge]

Right, but that's an uncomfortable solution. How do we know how long is long enough? Is it static? Can it deped on network? On hardware?

[dawn plover]

I mean, yeah, I'll probably just use Sendcustomeventdelayed, I just wanted to know if there's some "official" way to do it, because for me it's weird that it doesn't work at Start

[void ridge]

And playing it safe with a long delay is annoying to user experience

[grand temple]

So try it out and see what it takes. It might be as simple as the very next frame

[void ridge]

2 seconds has worked for me. If it's known that the amount of time will never significantly vary, then that's an answer

But I have no idea what determining IsUserInVR depends on

[willow tartan]

I generally wait for OnPlayerJoined before doing anything with the network apis

Though I haven't been using IsUserInVR

[tranquil thicket]

Hi! Can someone please tell me where can I set skybox material ? I feel blind.... I CAN'T find it no matter what

[dapper lion]

@tranquil thicket you have to set the materials shader to skybox

[tranquil thicket]

But where in the world... ? (I am newb to unity but still heh)

nwm... its hidden in "lightning settings" ... who would have thought....

[mild fern]

what video player works with quest? i know on karaoke the quest users can sing along now :o!

[dapper lion]

@mild fern architectTV and the revised version of U#sharp. those are the most public quest friendly videoplayers

[mild fern]

thank you!

[scarlet lake]

Just curious really, whats the maximum cap of Sync's udon can handle until it finally says i cant take life anymore and decides to stall or give up on an object completely? I ask because my new park is 100% udon and i tested it out yesterday with testers.. everything ran beautiful and overall shocked alot of people based on how great it ran.. but randomly one of my rides went berserk, checked out the compiled data and everything is perfectly fine.. it just acted oddly..

Basically the script is on the parent and the child follows as per usual.. i have.. alot of objects under udon nothing in the scene is animated now.. so i knew this would be an experiment really.. i suppose when we get the network update this may improve things some, but yes.. on the live version does anyone know the max capacity before Udon decides to say no more sync i cant take it anymore?

[stark adder]

I think the capacity on live is same as beta

200 bytes roughly

[scarlet lake]

oh jeez..

[stark adder]

Per serialization

Per behaviour

[scarlet lake]

I need some way of splitting it then

[stark adder]

Or just wait for sync update

[scarlet lake]

Yeah i suppose i can wait.

[stark adder]

You can sync upto kilobytes

[scarlet lake]

Still waiting for Cyans Alpha triggers as well.. its all a waiting game this heh.

[stark adder]

I'd say the safe amount would be like 20KB but their documented is like 47?

So that's quite a lot lot of data

[scarlet lake]

will need a calculator.. based on what i have done my brain cannot handle that amount with maxmum compression of textures.. each texture to considered weight plus format and crunched..

should be good but.. i wanted 100% and yeah.. lol i knew this would happen but just need to not overdo it till the update i guess.

[stark adder]

👍

I just stopped working on Live for my world.. just updating with new people on board but no features.. :)

On live I am hitting so many limits in my world so.. F live.. I am just hoping that sync update comes soon as sure people don't mind now but if it takes another month for the sync update

[scarlet lake]

UdonSharp has been remarkable during this, i have converted my old parks rides into fully scripted with a lightshow, every ride is lit with a script that changes between 20 materials/sec to simulate light.. from dark to light.. it runs maxed out fps on runtime too.. no lighting but them in the scene, yet you wouldnt know.. it confuses some people.. lols

[stark adder]

Nice

Yea couldn't imagine life without U#

[scarlet lake]

Yeah you and me both there.. actually i have @wanton bluff i was hanging with the other day.. he has.. a graph that needs some work but i think it may be due to networking again what we seem to be having.. i want to help him out because he's godlike when it comes to stage productions.. its his job and his passion.. but yeah i dont think the current version of Udon is up to the task so we will wait and see if the new sync can handle it i guess.

I made a vrc trigger system with Get.Component because a toggle will not work for what i have planned.. and everything graph related doesnt seem to act the way i wanted.. did something extremely basic and it worked so cant complain. lol

[stark adder]

One thing I am bit worried about in my case is that I am promising my players that once sync update is out everything will be much better and many new features but I am starting to get worried I won't be able to fit all of the things I want into the initial release..

[stark adder]

Graphs never acr how you want them :)

[scarlet lake]

Yeah.. i know that feeling all to well..

but at the end of the day Udon's not sdk2 im sure they will understand.

Yeah i stick to C and convert over to U# who needs graphs.. i sure dont. lol

[stark adder]

Yes lol

[stark adder]

And yes our community is very friendly and understanding but still I am that kind of person who will just feel bad if I am not able to deliver all features I said I want to..

[scarlet lake]

One of my friends mentioned something but i dont think Udon is anywhere near the level they believe it to be so.. although it might work.. with unity's terrible physics i do question just what would happen.. i will experiment with it still but overall its abit overkill.. my rides usually just start up and thats it on timer then end waits for input and thats settled..

But i was asked to make a ride slow down and act like a real ride like climbing up in scaled rpm.. and i see one way of doing this.. but it uses a weight system with rigidbody.. but then i went abit over the top and thought.. what if we created a weight system of each user depending on size of avatar.. that could dramatically alter a physical object as it shifts up or down in speed due to gravity.

basically im going over the top but the graph would be utter hell i would imagine.

[stark adder]

It would def be possible lol

[scarlet lake]

Well.. all i make is Theme parks on vrchat.. me and Wodan are the only one's that compete tbh.. and he refuses to learn udon.. so i decided to go one up and release for both platforms and with a much smaller download size.. so far.. 20mb every action on script, over 600 vrc chairs all synced too.. and all lights coming from material renders 20/sec everything max crunched 1024 max res.. no shadows no reflections.. and it came out absolutely perfect.. minus that one ride that seems to have an issue..

Still if its acting up i can just mess around with its Update some.. im sure its related..

[stark adder]

600 VRC Chairs

[scarlet lake]

Yes.. and i have to position those individually believe it or not.

[stark adder]

[scarlet lake]

due to a rides default position copy/paste is not as easy as i would like.. manual adjustment every single time.

[unborn hornet]

*architechTV

[dapper lion]

oop

[outer warren]

Are there any recent tutorials on how to make automatic doors? The video on the official vrc youtube isn't working for me.

[floral dove]

What's not working?

[outer warren]

I don't know I think it's the OnPlayerTriggerEnter node.

Cause this isn't the first time it hasn't worked for me

@floral dove

[floral dove]

I guarantee that graph and setup works. What happens vs what you expect to happen?

[outer warren]

nothing happens when I enter the trigger but I expect a block to move from one spot to the next.

[floral dove]

Take a look at the Player Detection graphs in the UdonExampleScene if you want to play with some working trigger zones.

[rough geyser]

How would one go about turning a post processing stack exposure setting “down” when using a baked lighting system through buttons with Udon graphs?

[balmy fiber]

Is there any way to change a Videoplayer's url using a button? (Like a Jukebox)
LoadURL() doesn't work when it doesn't get it's input from a textbox

[somber hawk]

You can but you have to use static URLs you include in the world, it can’t be dynamic unless you use the VRCUrlInputField for it since that’s the only way to initialize a VRCUrl at runtime.

So if you want buttons that play predefined songs you can do that. Add a component with a VRCUrl property and you can set it in the editor. In your code or graph you can get that value and give it to LoadURL

[balmy fiber]

This is what i did, but for some reason it isn't working

[somber hawk]

Yeah that looks right to me, maybe the musicChange method isn’t being called when you click the button?

You could also look at the console logs and if the video player is doing anything or erroring it’ll tell you

[balmy fiber]

I doublechecked and the button is indeed calling the method as the player stops when I press it, I'll check again for errors in the logs

[somber hawk]

It could be the format of the URL, iirc it’s strict and requires the https:// prefix for example. But logs should tell you if it’s failing to download it

[mild fern]

has any one done any work on true randomness with udon? Random.range be killing the flow in my world

i need the power of TRUEEE random

[native estuary]

Not really possible to make true randomness just inside unity

Guess you could run a webserver using random.org feeding the data into vrchat using a video player that's about the only way for true randomness in vrchat I can think of on the fly

Doubt you would need true randomness anyway just throw in some wildcards to how the numbers are generated to better suit your needs

[mild fern]

probably a good idea!

thanks 😄

[balmy fiber]

mm

I'm not sure about what I'm doing wrong

[mild fern]

is the U# one just the U# video player? what do you mean by revised?

[lavish rune]

Is there no way to make the wheels actually spin/turn using jetdog's udon car prefab? They seemed to in the sdk2 one, but in the udon prefab, there doesnt seem to be anywhere to specify this.

For that matter, is there any way to make the acceleration less sluggish? or change the controls?

[normal yarrow]

Hey so, I'm trying to get a global synced toggle, and I tried doing so with this Udon graph, does it look like it would work correctly?

Sorry for the not so great text quality, I tried to fit all of it in the viewable space I had.

Actually now that I think about it, this wouldn't account for late joiners, oof.

[somber hawk]

Glad you're able to see the error though, but that seems above my pay grade and the URL looks well formed to me. I'd be sure to try other URLs in case there's something particularly weird about that video (like video permissions blocking it), but otherwise I haven't seen that error before

[balmy fiber]

Hey, thanks anyway for helping me debugging it, I really appreciate it. I tried several videos but still, no dice.
The problems persists even when using AVPro instead of the Unity one, and autoplay also works fine, so I'm really at loss for ideas right now after tryng everything for two days :/
I'll try reporting this issue

[steel nova]

is there an udon function to manually transfer instance owner?

IE on interact > get localPlayer > SetInstanceOwner???

[floral dove]

Networking.SetOwner

oh instance owner

[steel nova]

er not per object but rather master

yah

having issues with synced variables if not instance master

[floral dove]

unfortunately, no. That's set when the room is created and not modifiable

[steel nova]

hmm

okay; so I have synced var bools that get changed on network events

however

if i join an instance late, for some reason, it sends the event but never changes the bool

[floral dove]

synced bools should be automatically sent from the owner of a given object to the rest of the players. When this happens, the OnDeserialization event will be triggered on all players who have received updated data.

You're kinda crossing the streams by mixing Network Events and Synced Vars. Events are ephemeral - they're sent and then they're gone.

[steel nova]

so if I set the local player as owner of the gameobject with the network script on interact it should fix this?

[floral dove]

Synced Vars are sent to people joining an instance

[steel nova]

the issue i have is I need persistence that can be toggled :p

[floral dove]

if you set the local player as the owner of the networked object then they will be in charge of the variables on that object moving forward, and their updates will be sent to everyone else

[steel nova]

perfect

thank u!

[somber hawk]

one more comment, are you testing this in game too or just in the editor? Make sure to test in-game to ensure it's not some editor issue. You can still see logs in-game too

[cinder marten]

How do I increase jump height?

[balmy fiber]

I've tested ingame too, no luck

[chilly crater]

If I dynamic bone a synced object, and have two local DynBone Colliders that gets updated to each hand. How crazy will it get if I get multiple people working at it? (manipulating the hamster)

https://puu.sh/HxNvl/700fcfb703.gif

This, but for each person adding to it.

I'm talking about the networking side of thigns.

I think i was smart about it, and have the collider update to tracking only happen inside of a player trigger stay.

[coarse crane]

Hi, I have been trying out instantiating prefabs in udon, but am struggling to find how to destroy them via the graph view. Is this possible? thanks

[chilly crater]

How do you want to destroy them?

timer/trigger/onuse/ondrop ?

[coarse crane]

trigger I think, I basically want to have boxes that can be spawned and carried to a trigger elsewhere, but I need to be able to remove them once that has been done. I got the collision stuff working but am really struggling on this bit. thanks

[chilly crater]

IIRC, you want to hit tab to search instead of space for the correct node.

Destroy. Should be the second one down.

[coarse crane]

oh nice, I was struggling with the search, that explains it. checking now

yea that's working, cheers

[chilly crater]

tab searching helps sometimes.

Especially if you know it is a unity/C# ability and it isn't showing up in spaceebar search. If it isn't there, it is either blacklisted or wrong terminology.

[coarse crane]

yea, that's super useful

[tame ruin]

so is their any tutorials on creating a ui menu? cause i would love to do a ui menu for toggles e.g mirror's ? or if someone could point me in the direction of a pre made one for udon would be greatly appreciated.

[dapper lion]

theres a premade mirror system by the Udonvr group. have you tried that out yet?

[tame ruin]

nope can you link me to it =p

[scarlet lake]

do i need to do somthing whit udon for the object to be able to pick it up

[dapper lion]

needs collider

[scarlet lake]

still not working

[dapper lion]

you sure? try setting it to convex. and also add an empty udon behavior and set “sync position” on so it moves globally

[scarlet lake]

im gona try do it convex maybe that will work

[floral dove]

PS the UdonExampleScene included with the SDK has working UI menu examples, including sync.

[scarlet lake]

i can grab it but its flyng away xdddf

[dapper lion]

set rigid body drag to 1

actually wait, i think its “is kinetic” that stops it from floating away

[tame ruin]

so what do i set in the function box? to make it work? https://gyazo.com/85c6f1223e4448a38e31a27ceb7c8e54

[cunning mist]

The first half of this video covers using UI Toggles and might be what you're looking for.
https://youtu.be/y-YSWkJtutI

[tame ruin]

Thank you kind sir!

ok so for some reason i can only input UdonSharpProgramAsset into the box next to where i place my script. https://gyazo.com/ebe5131a8756d6a374f6219d9cce57db bah im derping out over here.. is that correct or ?

dw got it

XD

[stoic mountain]

Quick check : iirc its not possible de Instantiate usable pickups at runtime. Is there a limit to the number of pickups in a world (to have a storage of inactive pickups available to spawn), and guidelines for maximum number of active (held or not) pickups ?

[brittle pebble]

I'm looking for Udon video player that works for live streams. Does anyone have any recommendations?

[tame ruin]

so after looking at the video posted above and following it bit by bit "excluding creaitng the collider udon script" i can say im officially stumped as it just does not work at all. heres my hierarchy if someone could graciously help me out of this tiny little issue. https://gyazo.com/33e726fe4e5f9a9b735a5bac1231cee2

[night viper]

Looks like you are not sending any custom event (string) to the behavior

[tame ruin]

what exactly do i put their?

if im using a graph i made myself ? and not one he made in the video?

[night viper]

Depends how the graph looks like. If you created a Custom Event, you use the exact name you used in the graph. The button will then tell the graph to execute that event (strings are case sensitive)

[tame ruin]

https://gyazo.com/850632bb2db70d3963763fa19d4ff238

this is the graph

[night viper]

ah, is an interact. Then you would select this on your button (instead of "send custom event (string) )

[tame ruin]

bro. just wanna say i love you. been puzzled trying different things for hours..

[tame ruin]

new problem has arrised i got a friend to test my world out in vr and they are unable to press any of the buttons. "they cant see the lazer to press any of the ui. E.g the usharp video player / the ui menus ive been working on for the past few hours.

[grand temple]

@tame ruin do you have a trigger collider that surrounds the area?

[tame ruin]

so i have it on the parent but not the actual button with the script. do i need to add it to the button ? https://gyazo.com/05828b98d6255ec7369b8c9e96e408ed tho i do have a big box that triggers the mirror off when leaving it .. would that be the cause? https://gyazo.com/7da11b3a22004577c4ab4fa3a8324960

[hollow seal]

are web requests possible with udon?

[floral dove]

You cannot make generic web requests with Udon. You can use the Video Player to load videos from external sites, and we'll release a Dynamic Image loader to load in images, but we currently have no plans to allow reading/writing from arbitrary web servers.

[hollow seal]

ah ok thats a shame

i had a cool idea, but it would depend on web requests

[willow tartan]

still no news on when the dynamic image loader is coming, I suppose?

[stark adder]

🤔 Well we made our own image loader 😄 can load any size theoretically.. But don't recommend 😄 Works both PC and Quest no need for any kind of untrusted URLs or whatever

Currently we're using it to transfer data into Client from outside

Safe limit is 90000 characters 🙂

Though one problem is it takes about 35 seconds to load all those 90000 characters 😄

[floral dove]

oof ouch owie

[scarlet lake]

Why does this sound exactly like how GPU used to work in gmod wire? lols

[stark adder]

🤔 Never played Gmod so

[scarlet lake]

it was runontick back then.. it was not fast enough to keep up with the client request.. we used to use GPU and do exactly what your doing there 🙂

[stark adder]

😄

[scarlet lake]

some sort of compression is required maybe? some way to speed up the process

[normal yarrow]

I'm trying to make a synced WWE entrance mixboard, but the sync isn't working right at the moment (not using any of the Network Beta stuff yet).

I can imagine if I did use it, it'll probably make things a lot easier.

[scarlet lake]

Yeah.. i imagine it would work a ton better.. i have already advised a friend of mine who is doing what your doing to get beta.. his dreams are way to advanced for me honestly and the graph alone is all midi synth with inputs he plugs in.. way over my head.. but he's using live right now and is not getting anywhere.

[normal yarrow]

I would get it but then I'll be separated from everyone else, lol.

[scarlet lake]

Yeah i understand.. its not been easy for me.. but i have built my world soly on C thanks to sharp which i then converted over to U# and its worked flawlessly but i see occasionally all these updates beta is getting and i must say.. im kinda jelly.. but to use it means separation and i cant do that with the people i ask for assistance when i release a test.. they are all live so im kinda stuck.. but all good.. i guess we just have to wait for a release.

[full ginkgo]

does anyone have an Udon prefab that moves multiple gameobjects to a location/resets position?

[floral dove]

I can make one for you real quick

[full ginkgo]

I've tried messing with some of Jetdogs graphs but something isn't lining up.

[full ginkgo]

bet ❤️

[floral dove]

@full ginkgo - here you go! You should be able to import this into a project with the latest SDK, open the scene, and Build & Test with at least 2 players. The only thing that's a little funky is the angularVelocity doesn't totally zero out, but it does most of what you'd want.

The ResetCube object has an UdonBehaviour with a 'targets' variable - you can add/remove GameObjects here to have them reset when this object is Interacted with

each target object should have the "ResettableObject" UdonBehaviour on it, this will reset the Rigidbody, which is what you want if they're physics objects.

[full ginkgo]

adding it to my objects right now. I don't see the Public Variables on my end? @floral dove

[floral dove]

hm - do you have any errors in your console that might be keeping the program from compiling?

the variables should show up as soon as the program compiles for the first time and learns that is has them

[full ginkgo]

getting the following in my world and a fresh project importing the scene you sent:https://gyazo.com/4266fe07e0311a328d8a90b3c6756442
along with attached.

[floral dove]

ooh- you've probably got an old SDK, that was added somewhat recently. Grab the newest version and import.

I've gotta run to get ready for our VRChat Dev Stream, but I wish you the best of luck!

[chilly crater]

Is there a way to approach Finite State Machines with udon graphs?

[full ginkgo]

worked with new SDK, but 'tis a laggy way. got a lot of objects I'm resetting

[stark adder]

Ok WorldPersistance Now you got me hooked up on good cocaine

[stark adder]

Welp I must say I loved the all the Udon Parts the most from the Dev Stream 🙂

[normal yarrow]

I'm pretty hyped for the new Udon stuff, and also Unity 2019.

[stark adder]

Yea Unity 2019.. Gimme Gimme

[floral dove]

Yeah, Unity 2019 is so close. We've been running a beta of the client for months and it's super smooth.

[sweet sluice]

https://ko-fi.com/takatoandbeast/shop

How do I determine what platform the script is running on, e.g. if (Application.platform == RuntimePlatform.Android)?
Please ping

[grand temple]

@sweet sluice simplest way is to make a public bool and just manually set it to true when you are uploading the android build. Automated way to do it is if you are using udonsharp, you can surround your code in #if UNITY_ANDROID and #endif

[normal yarrow]

||HDRP (and maybe raytracing) support in 2019?||

[grand temple]

Unfortunately HDRP requires completely redoing all your shaders, which is doable in a game where you author all the content, but not really feasible in vrchat where everyone uploads their own shaders. Doing so would require wiping pre-existing content, which isn't gonna happen

[normal yarrow]

This is a sadge moment.

[night viper]

Are you trying to toggle the "Vrc Seat Folder" gameobject with everything inside? Or toggle single gameobjects inside "vrc seat folder"? If it is the first one, you can use the same graph as the first picture you showed and plug the vrc seat folder on the public variable instead of the mirror (on "target")

[terse sun]

So are we at a point where we dont have to use a massive state machine just to get simple locks?

[smoky tinsel]

I'm having a bit of a weird issue with using random number in Udon and syncing it. The random number gets passed to a text object and displayed.
But for some reason, the number lags behind by one instance for everyone who's not the owner. So if Player A presses the button, they see 8. Player B and C still see the default uninitialized number. Player A presses again, they see 6. B and C now see 8. Player A presses again, sees 9. B and C see 6, and so on.
The variable is synced, the text objects aren't (and don't work if they are, either.) Here's the graph that I use.

[fallow cradle]

@short sluice usage of udon is not required to reach stable lobbies of 80 people. (It requires hiding a large majority of avatars or enforcing avatar stats however)

[fierce pond]

Good morning! Question regarding the media players, specifically AVPro, what is the best stream rate (bitrate, resolution, etc) to host a stream in an Udon world?

I'd like to avoid the issue where the player will not work for some people in the world. This seems to happen when the world reaches a certain number of people.

[slate mesa]

This is because everyone runs the event at once, and after that has happened the owner will send out synced variable values. You should have any non-owner code run on an "ondeserialization" event, which is the event that occurs when values are received for everyone except the owner

[smoky tinsel]

Ahh. So the part of the graph from the Owner stays the same, but the latter part where the game objects are being set active should be handled through a ondeserialization instead of an event that is run?

[fading cipher]

Is there anywhere I can find descriptions and documentation about the new gesture input reading system they implemented a month or so ago?

[grand temple]

do you mean input events? https://docs.vrchat.com/docs/input-events

[fading cipher]

Yeah, taht

Thansk!

bruh I can't type

Ah, that's looking like a bit less support than I thought. With the way everyone described it, it sounded like it was supposed to support all the gesture-like buttons as well 🤔

I was hoping to be able to see if your finger is in a "pointing" position, but I think I was thinking about this wrong. VRChat probably has never had the ability to see if an Oculus controller's button sensor for a finger is being triggered, has it?

I was thinking I could check to see if a person was pointing by checking for grip clenched, thumb "down" (not necessarily pressed, but the thumb sensor reading the thumb is on it), and finger "up" (the opposite of thumb)

But I guess I can just check for inputGrip true and inputUse false

[scarlet lake]

So ive been gettins some errors but have no idea how to fix them. Ive reimported the udon sharp as well as the vrc sdk a few times to no avail.

[chilly crater]

How would one go about formulating a state machine in UdonGraph. Or is this something that can only be approached in U#?

[fading cipher]

@chilly crater I'd recommend using Unity's animator, since that basically is a state machine

Animations support variables of type float, bool, int, etc.

So you can very easily set up complex states and connect the animations' variables to an udon script

[chilly crater]

That is super helpful

[fading cipher]

Used the animation system for a state machine once, it was great until my own lack of skill made it a bit spaghet 😅

[chilly crater]

See, I got stuck in the box. That is outside the box thinking. And now that it was pointed out I can see how easy it is now...

Animator Layers
|> State Graph
|> State1
|> State2
|> ETC

then you have a script on the object for each state.

[floral dove]

First - restart the editor, some or those errors are just auto-importing stuff happening out of order (TMPro and Cinemachine). If that doesn't resolve all, try updating to the latest non-beta releases of both the VRCSDK and U#, looks like U# is referencing types in a later version of the SDK than you have loaded.

[scarlet lake]

okay ill give it a shot

[sharp briar]

So, I've made pickups before and i struggled but they work fine. I'm working on a new world and for some reason I can't get pickups working? I'm pretty sure I did everything the same. The point I'm at is I have a collider that is able to be picked up but the mesh stays behind.

[floral dove]

make sure the pickup and collider are on the root of the object - you can check out the example scene to see many examples of working pickups, like on Cubes > PickupCube

[sharp briar]

Turns out I had it set to static

[floral dove]

err - static is for objects which you don't want to move...

[restive veldt]

Hey, is there a way to get a list of all players in a trigger?

[grand temple]

yes, just run the getplayers function on an array of vrcplayerapi

make sure you set the playerapi array to be a length like 82 so it never runs out of space

that's just your max player count * 2 + 2

this is the udon questions channel, it is about world development

[floral dove]

?upload

[hidden marten]

You must obtain at least "New User" Trust Rank in our Trust and Safety system in order to upload content. You can get this by just spending a few hours in VRChat, hop some worlds, and make some friends. Give it some time and you'll be able to upload content in no time.

As an aside, you must have a VRChat account to upload content. That means you can't use a Steam account, Oculus account, or Viveport account to upload content like worlds or avatars.

[fair terrace]

So, I found a free chess game, but it's for SDK2... Would it be possible for a Unity noob like me to convert it to a SDK3 compatible thing?

[floral dove]

That's likely a quite advanced project to tackle for your first go with Udon. I recommend you start here if you want to make things with Udon (SDK3): https://docs.vrchat.com/docs/getting-started-with-udon

[fair terrace]

dang, why does the only normal SDK3 chess game have to be paid?

[fair terrace]

How do I make a thing stop moving when I let go of it? Closest I can get is turning "Use Gravity" to off, but if my arm is moving while dropping it, it floats across the room.

[grand temple]

turn on "iskinematic"

[fair terrace]

I kinda thought that's what that was for, but when googling "is kinematic unity" all I got were references to skeletal structure things

[grand temple]

Really? First thing that comes up is https://docs.unity3d.com/ScriptReference/Rigidbody-isKinematic.html

[scarlet lake]

I use iskinematic on all my rides all runs beautifully.

[fair terrace]

Re-reading that, I guess it makes more sense now that I know it's what I was looking for, but my derped brain warped the info into relating to avatars and skeletal connections

[scarlet lake]

Well.. to me it just looks like it says parent and children.. which it does apply on.. but some on my children on said parent with it I seperate for other functions.. don't need them. All kinematic after all.

[grand temple]

yeah, it is a weird term. Should be something like "physics enabled"

but unity is old and that's something that has been around for a looooonng time

[fair terrace]

I'm 40, a high school drop out, and everything I know (computer related) is self taught... I'm amazed I've gotten as far with my world as I have... 🙂

[scarlet lake]

We are very much alike there, I'm self taught too and I'm. 37 coming 38 and yeah a drop out also..

[grand temple]

to be fair, there is a very big difference between a kinematic rigidbody and not having a rigidbody at all

[fair terrace]

but yeah, I needed a new thing to poke at an old SDK2 chess set I found...

It's the "board poking object" that is tied to the SDK2

[scarlet lake]

Chess is a game I have never fully understood unfortunately lol

[fair terrace]

I remember all (most?) of the basics, but suck at the overall game

I'm working on building a "mega entertainment complex" kinda world...

[grand temple]

I'm kinda confused... what part is complicated about making a chess board? Literally all you need is a button to reset the positions of all the objects

[fair terrace]

Rooms with games, probably a bar/chatting room, and a stack of "event stage" floors

[scarlet lake]

I see.. well that goes hand in hand then as I create theme parks so naturally im Building casino related games such as slots etc in mine, despite the rides, all under udon.

[fair terrace]

It's a chess board with an optional AI (for those loners)

[grand temple]

how is that SDK2 though?

[fair terrace]

the "piece to use if not in VR" was tied to the SDK 2, because of the syncing or something?

I'm not really sure

[scarlet lake]

If it has scripts you could just convert them over to U# with sharp.

[fair terrace]

But i believe most of the stuff is automagically snapping to grids and not allowing illegal moves

[broken bear]

what swim system allows bouyancy that I see in some worlds?

[grand temple]

The one by Hirabiki, search for them on twitter

[broken bear]

ah, didn't realize it was the same, thanks

[fair terrace]

my next big hurdle with my world is gonna be lighting and stuff that's "synced" to what's playing on the stage's video screen...

I've seen it done, and from what I can tell is that it's using a tiny (single pixel?) camera and using that color info for laser beams and stuff...

[grand temple]

You can make laser beams that just access the same texture as the video, and set up the uvs so they're only using a specific portion

[fair terrace]

Yeah, I have access to someone who's done it already, but I wanna wait till I'm closer to the "decorating" phase of "construction"

[grand temple]

the reason I propose that solution is because cameras are expensive

[fair terrace]

anyone know if there's "VRChat ready" stage lighting things in the unity asset store (hopefully also in the free category)?

or can anyone vouch for one of the paid ones?

Like this (https://assetstore.unity.com/packages/3d/props/electronics/pbr-stage-equipment-84617) does anyone know if the animations and stuff will work in VRChat?

[grand temple]

You can pretty much always use the shaders and models, but some assets will over-use scripting for even the most basic things when they totally could've used animations

You can look at the package contents and see what scripts they use

Animated texture is something that should be done in shader, periodparam sounds like something that should be done in an animation, not sure what materialinstance is

[fair terrace]

But I'm trying to set this place up for DJ streamers, would animations be flexible enough and not look "faked"?

[grand temple]

if the colors pulse to the music, it doesn't matter what direction the lights are pointing in

[fair terrace]

I disagree, but I do see your point, at some point, I'm gonna have to sacrifice realism for performance

[grand temple]

sure, there's an advantage to syncing the movement of lights as well. But at that point you'll have to create the performance inside the world rather than just putting together a youtube playlist

[fair terrace]

Again, this world is for DJ streamers, mostly friends of mine on twitch, the intended audience is already decently versed in setting up stuff to music that looks good

[grand temple]

but do you want to provide a world for them to use, or do you want to constantly collaborate and add stuff to the world

there is no wrong answer, it's just up to you

[fair terrace]

I'm fine with doing custom sections, or adding "prefab" layers for more people.

I'm not too "artsy fartsy" but I can assemble things pretty well...

If someone gets on board that is artsy fartsy, I'm not opposed to collaborating...

Right now, it's a "see how much I can get done myself" thing, so I have something to show people to get them interested

how many video players can I get away with having, if they're sectioned off and separate from each other, in one world?

also, can I turn a sound bubble into a sound cube?

[grand temple]

if by sound bubble you mean a normal audio source, then you can if you make an udon script to automatically change the volume based on position

No idea how many video players is too many, but I'd recommend if you have one playing in another room, just have it entirely disabled for the players that aren't in that room

You'll have to have some way of making sure the owner of it always has it on, though. Or transfer ownership to someone else when the owner wants to disable

[fair terrace]

That might have to wait till I get closer to finished with the "get to a point that's worth showing off" phase... 🙂

right now it has a "could be either a subnautica base (if you could see water somewhere) or a space station (if you could see space), etc" feel

or maybe a hospital...

[fading cipher]

Is there any way to check if a desktop player is scrolling their mouse?

[fading cipher]

I'm thinking there isn't, so I'll do some raycasts instead for that.

[fickle stirrup]

@fading cipher

// Mouse
if (Input.GetAxis("Mouse ScrollWheel") > 0)
    Debug.Log("Up")
else if (Input.GetAxis("Mouse ScrollWheel") < 0)
    Debug.Log("Down")

(but not remember, which one up and which down)

[fading cipher]

Oh shoot that’s awesome!

Will test in 5 minutes lol

Yay, literally was a 5 minute fix https://streamable.com/jwv60a

Thanks so much!

[grim sapphire]

Hello!
I am a Japanese user!
I'm using a translation tool, so I'm sorry if this is not the correct language.

I have a question about a serious problem.

I'm building a UDON world using the latest SDK3.
This world is compatible with Quest users.
However, I'm having a problem.
From the Quest user's point of view, the avatar and world textures or meshes seem to be doing something weird.
It's hard to explain in English, but... Flicker? Jaggy?
In the room with VRCWORLD (*respawn), there is no such problem.

There is no problem from PC users.
This is only happening to Quest.

Do you have any further information about this?
Any suggestions on how to remedy this would be appreciated!

[obtuse agate]

#world-quest message

[grim sapphire]

Thx a million!

[strange shale]

heya so i've been messing a bit with the haptic feedback options in the udon pickup script
(specifically these two nodes)

cant find any documentation on them so i thought i'd ask some questions here

basically i've been testing them to see if i could make some custom haptics occur
made this system to hook them up to some UI sliders for testing ingame

seems the generate and the play nodes do bascally the exact same thing when triggered no matter how i change the values on the generate node

was wondering if this is how its meant to be or perhaps im just not doing it right?

either way so far all i've managed is generating the same very short simple haptic response

[void ridge]

It looks like these nodes are dependent upon pickup objects. Interesting, I didn't know those existed. When I do haptics, I've been using VRCPlayerApi.PlayHapticEventInHand
https://docs.vrchat.com/docs/players#playhapticeventinhand

If you're specifically looking to do haptic stuff with this pickup, probably continue using those, though I don't know how they work, only guesses

GenerateHapticEvent makes sense to me and looks very similar to PlayHapticEventInHand, and my guess is that it just determines the hand based on which hand is holding the pickup

PlayHaptics, I have no idea why something like that needs to exist

But anyway, for duration, frequency, and amplitude: duration is in seconds, so a value of 0.1 would be a very quick click, and 1.0 would be a full second of brrrr

for frequency, I find that stuff between 50Hz and maybe like 200Hz is most reasonable. I think the VRC client's haptic event when you interact with stuff is in that range

amplitude has a big weirdness: it's extremely different between SteamVR and Oculus. On Steam hardware a value of 1 (full) gives you butterfly kisses, and on Oculus a value of 0.5 is like holding an exploding firecracker in a coffee mug

https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback/p/equalize-haptics-across-platforms

[strange shale]

hey thanks for the reply :3
this is indeed helpful info
there's at least a bit of documentation info and i now know that you can do haptics through the player API too
did not know the haptics range only used a value of 0-1 so i will tweak my testing setup to give it another try i think x)

also good to know it gives different results for steam controllers... may have to enlist the aid of a buddy with steam controllers at some point to make sure they can actually feel anything

[fading cipher]

@strange shale I’m in the same boat rn figuring out what values to use for UI interaction. Here’s hoping 0.1 amplitude and frequency are good.

But side note, does anybody know if there’s any Udon exposed methods I could use to check if a person’s thumb or finger is resting on a button with a sensor, since most VR controllers these days have those sensors?

Like testing if a person’s thumb is down without actually checking if they’re pressing the button, since button press input events are only bools

[strange shale]

well something definitely works now
anything below 0.2 on the amplitude i can notice after that the difference between around 0.2 and 1 is honestly difficult to tell.

and this is only the amp slider
neither duration nor Frequency seems to do anything at all
even at 0 the feeling seems about the same... strangely

im going to try a couple of things to see if maybe its my setup being funky

[strange shale]

welp... starting to think maybe vrchat just can only interact with the amp for my specific controllers (oculus rift controllers)
oh well... guess i will have to make due for now

not much more i can test anyway >__>

[fading cipher]

Am I still supposed to completely remove the SDK from my project before I update it with a new version?

And if so, am I just deleting a folder...?

[floral dove]

it's not always necessary, just recommended if your'e having issues. If you want to do a clean install, delete:

• Assets/Udon
• Assets/VRCSDK

Which one of these is valid. I can't remember which one doesn't work. I'm planning to set it to Null once I'm done with it.

[fading cipher]

So if I'm updating, can I just drop the unitypackage in and it'll automatically overwrite and everything will be fine?

[floral dove]

make sure to import it and not just copy it in, but yes

[fading cipher]

There's a specific way to import a unity package? I mean usually dragging/dropping or double clicking is enough, unless there's a special set of steps you're referencing e.e

[chilly crater]

If the import window opens, you are importing.

I think Momo means if you copy the SDK from another project or just a folder into your assets folder.

[fading cipher]

Ohhh yeah no I'm not doing that, thanks!

[flint urchin]

Both are valid

[chilly crater]

Thanks

[floral dove]

One only works with VRCPlayerApi and is autogenerated, the other one can be used for everything including VRCPlayerApi and has easy-access True/False flows built-in.

[fading cipher]

So how does this Input Events system work? Can I not just check if (inputJump == true)?

[grand temple]

no, the whole point is it's event based, not polling based

here's an example that uses it

[fading cipher]

Alright 🤔 so I just need to have a set of bools that are triggered by those grab events instead of checking them by themselves

[fallen chasm]

ey, I'm trying to make a simple udon graph to toggle a parameter on, then off after a set amount of time...

I've got this, but it only enables the parameter... so I'm missing something in the delay... Don't suppose someone can help me figure this out?

[night viper]

You can do timed events by using "Send Custom Event Delayed Seconds"

[fallen chasm]

I'm not entirely sure how this plugs into anything

(but maybe if I learn it, I can solve another issue where I'd like to make something send a network event)

[night viper]

This will turn the animator bool "name" to true on interact and after 20 seconds, it will turn it off.

[fallen chasm]

that's much easier than what I was trying to build

(didn't work)

I'll give yours a go @night viper

thanks

[night viper]

Hope it works, also I am not sure if each time you interact with it the timer will reset, or it will fire after every 20 seconds of every Interact event sent

[fallen chasm]

working out that bit now -- it seems to get stuck in the event, even though the bool is indeed set to false in the params -- but that could just be my condition setup

(or a unity bug that will behave fine in game?)

anywhoo... Thanks a bunch... I feel like I just leveled up with that bit of custom event knowledge

oh... I can get rid of two nodes if I noodle up the green and yellow to that last setbool

a fine nugget indeed

[night viper]

So it does not fire the "_setBool" event? Could it be the way the event is called? I know that you cant name variables with a number at the beginning, but im not sure if you can use any letter at the beginning of any custom event

[fallen chasm]

nah, it fires -- the udon stuff is working great now

it's my animator

the exit arrow from FS-Electrify is supposed to trigger when that param is false

and it does... if I don't use exit time

but I kind of need that to last 25s...

which, I suppose I can do with the udon timer

derp

problem solved XD

[night viper]

oh nice!

[fallen chasm]

well... better test first O.o

awesome!

all working now

oh man... I'm excited to get the network stuff working now

not even kidding, @night viper, you just unlocked a door for me here

I haven't tested this yet... but... does that make sense?

seems a bit excessive, but without a network event that can also have a custom delay, I'm not sure how else to go about it

local test didn't work... but maybe that's not testable using two local instances of vrchat?

I'll have to pester some friends for a little playtesting

[scarlet lake]

🍜 that's a lot

[fallen chasm]

I wonder... is it necessary to set the bool up front? Shouldn't the network event affect everyone /and/ the person who triggered it?

this probably isn't the best example, since it's timed

but a regular "set bool" that is meant to happen immediately... I would think you would only need it to happen in the Custom Event, and the interact event would just be the sender

[cunning mist]

VRChat uses underscores to denote it's internal calls, so to keep clients from tossing everyone into a single chair or something, Networked calls on events that start with an underscore just become a local call.

[fallen chasm]

@cunning mist Thanks! you probably just saved me from a ton of confused testing...

[fallen chasm]

would this send the custom delay over the network?

I initially assumed that only "SendCustomNetworkEvent" was global, but are all of these Send nodes meant for network tasks?

[chilly crater]

With an UdonGraph, how do you check if the triggerenter has a specific component?

I don't care what enters that trigger, it has to have an animator to mean anything.

Like this?

Or is this an isValid check?

[fallen chasm]

isValid just makes sure the thing isn't null

I'm getting mixed messages -- so do you need to know what specific component, or not?

I put this together earlier to detect when one thing enters the proximity of another

maybe that's what you're after?

[chilly crater]

I'm getting an error on my trigger enter, because it is trying to grab a component that doesn't exist.

[fallen chasm]

my graph didn't use triggers -- just a bool that tested against their positions

[chilly crater]

That wouldn't work for me. Both of these objects are actually too close to each other to matter.

nevermind, that would work...

Just seems so... inelegant.

That, and if I put in more of the AI, it would just bloat the script more.

[fallen chasm]

so... I've set up a bunch of netwok stuff

but now my world drops frames pretty hard every 10 seconds or so

kinda wondering if there's a thing to prevent the network calls when they aren't in use

(cause I'm pretty sure that's the only factor that's changed)

ah, I think I see the culprit -- which, ironically, is related to this proximity stuff

[chilly crater]

There's probably some trigger component check we aren't finding.

[fallen chasm]

I'm attempting to make that graph into a networkable thing, but on update... that likely means it's firing until it overloads, then has to catch up with some frame drops

(totally guessing here)

well... I think my solution is gonna be to switch this back to a local event, and trigger a second one that only fires once

or at the very least... not fire this network event off of the update

something like this, perhaps...

aww yiss, that solved the frame dropping

note to self: do less stuff on update XD

[fair terrace]

VRC_Trigger is missing/not working for me, did I do something wrong, or is it an SDK2 thing?

OMG, I need to learn how to build a node graph to make a mirror toggle button in udon?

[fiery yoke]

Udon replaces Triggers yes. But there should be simple prefabs provided with the SDK. Not sure if there is a "Mirror Toggle" but there is a lot of people who already made those. You dont need to learn it yourself, if you dont want to, but then you need to know where to find the thing you need.

[fair terrace]

The only place I have found so far for VRChat things is this: https://docs.google.com/spreadsheets/d/e/2PACX-1vTP-eIkYLZh7pDhpO-untxy1zbuoiqdzVP2z5-vg_9ijBW7k8ZC9VP6cVL-ct5yKrySPBPJ6V2ymlWS/pubhtml#

[fair terrace]

I feel like I should be able to make this happen with any object that has "Udon Behavior" on it, "ToggleGameObject" as the program source, and the targetGameObject set to the VRCMirror

[fair terrace]

Nevermind, stopped trying to use the VRChat SDK udon scripts and followed a video guide on how to set up a toggle.

[paper plinth]

Or u can use a prefab

[coarse crane]

Hi, I also had a question about timers, and the above is really useful, but when I check the graph, I don't have an option for the udoncustomeventdelayedseconds

do I need to update my sdk?

[dapper lion]

how old is it?

[coarse crane]

2021 01 28

[dapper lion]

i think timers and delays were a thing back then. but it might be in the new sdk. i started working on a sleep system alarm clock and ive been only half successful lol

like a week ago so im not sure if its new or old

[coarse crane]

cool thank you. yea Im working on some little ftl/ sid meier's pirates in space kind of thing. Hop between sectors, upgrade ship, put together rockets and then fire them etc, but I need timers for the weapon recharges, and for triggering the enemy firing etc, and the graph with it checking on every frame for every timer forever just seemed wrong

yep, perfect, update solved that

thank you

[dapper lion]

you can set a timer event via firing a normal custom event, but ig youd also want to stop it which would be a bit weird in graph

the way i did my alarm was “onawake” basically. and you move the sliders and hope the counter updates and it just slowly counts down until it plays a really annoying sound

so its pretty inefficient but in theory: it should work fine since its designed for sleeping lol

[coarse crane]

yea for my progress bar I might just make it an animation - if I know its gonna be 5 seconds then just play the animation while it does the delay in the background

[dapper lion]

you could do transforms/change the slider value over time

[coarse crane]

oh cool, yea that sounds good then

[dapper lion]

idk whatd be more performant tho. i feel like value changing would be most performant if its all locally done

animator might do the same thing

[coarse crane]

heh, most performant is probably just putting "loading" on some text and letting them work it out, so thats gonna be my first step I think

I havent even looked at getting this stuff working for multi user yet, and I fear that is going to be pretty horrible

[dapper lion]

it shouldnt be too bad when the UNU happens

[coarse crane]

what's that sorry?

[dapper lion]

“udon network update”

it should make it easier to get stuff in between players. especially for graph

[coarse crane]

oh great thanks, I'll just get it sorted for one player now then and save some pain trying to get mp working until then

[true ocean]

Hi, was wondering if there was a combat system for udon or if anyone has a combat system prefab?

[fiery yoke]

lol I actually just talked about that in a different server. The problem currently is that VRChats ping is usually quite high, especially for non-americans. So its not really "meant to be". Maybe that will change if Regional Servers are deployed at some point.
And its high for a competitive combat situation. Its still low enough to work with it, but its not "great"

[chilly crater]

Is there an easier way to differentiate collision/trigger events on udongraph?

My current case is that I only want trigger events from objects WITH animator components

Well, any way to differentiate them.

[floral dove]

Trigger events will only happen for objects with colliders that have isTrigger checked

[chilly crater]

Yes, but I'm getting an error when something goes into the trigger and doesn't have an animator

[chilly crater]

https://puu.sh/HySgW/ffc7ab9d05.png

[floral dove]

right - so either check that the Animator component you've got IsValid, or use layers to limit which objects trigger collisions

the former will be an easier fix, the latter is ultimately more performant.

[chilly crater]

Does default automatically check all layers? Because said object erroring is on the player layer, since it only interacts with players.

[floral dove]

I believe default interacts with all/most layers (don't have the matrix up at the moment)

[chilly crater]

Okay, that sould fix my issue.

Thanks

I'm still gonna make the trigger less tall.

Weird, the isvalid check isn't working,

I'll just try a valid avatar check

[steel plover]

Problem: I've got an udon script that is meant to instantiate a pickup-able object when fired. The object spawns fine, and I use a custom event to spawn it on all clients. However, The object seems to not sync correctly between clients, as when one player picks it up, nothing changes on the client's end. To check where the problem was, I placed the physics object in the world directly, and that seemed to work fine pickup-wise. How does one cause an instantiated object to sync between clients? Is it possible yet?

[floral dove]

Instantiated objects cannot be synced, sorry: https://docs.vrchat.com/docs/networking#vrcinstantiate

[steel plover]

aaaaa rip

thanks

[chilly crater]

ObjectPooling is what you want to go with there.

[steel plover]

i'll look into it

thank ya kindly

[fading cipher]

So when posting an SDK3 world for android, are there any specific Udon methods or something that I may have programmed that would make it not work for android?

Also, just in general, when building for android is the workflow that I'm supposed to duplicate my project as a second project, switch to building for android, then upload to the same world ID and VRChat will automatically make it all work?

[floral dove]

You don't have to use a separate project or even a separate world, you can use the same world and just swap it over, though you'll have to wait as all your assets are recompressed. This makes the process easier: https://github.com/JordoVR/EasyQuestSwitch

[fading cipher]

Thanks! Will check it out

Should I expect any of my existing code to break in any way when switching to android building?

[floral dove]

No - input fields are not usable on Quest but most everything else should work. Quest Video players can only play direct links to .mp4 files, not YouTube/Vimeo links, but the code won't break, they just won't load those videos.

[fading cipher]

Awesome, good to know too, thanks! My world is more likely to be an adventure game than it is a "watch videos and stare at a mirror" world, so I don't think I need to worry about that

[dawn forge]

Has anyone ever came to a single gameObject to manage all data? Since I can't really instantiate classes(Of players/their values) I was going to just instantiate Gameobjects that holds my scripts and their variables, then have these Datasources network to each Datasource objects of each person across the network.

[grand temple]

instantiated objects won't sync

if you want to hand out a unique script and object to each player and sync those values, you can use a pool of objects. "Simple object pool" on VRCPrefabs.com/browse is built for that exact purpose

[dawn forge]

That sounds promising! I will check that out. Thank you!

[last swift]

I'm trying to setup a OnTriggerEnter on a gameObject that has a tag of "catcher" but it doesn't seem to like how I'm coding it. Is there another way to do trigger collisions? Error message - Method UnityEngineGameObject.__get_tag__SystemString is not exposed in Udon

I'm using U# btw

[grand temple]

you can check the name or layer of the object instead

[last swift]

I changed the code in my if statement to target.gameObject.name == "catcher" and that fixed the error I was having so that it will run, but the objects didn't Destroy when hitting the catcher game object

I double checked the name and it is spelled correct

[grand temple]

I wouldn't be surprised if your script is crashing. There is such a thing in udon as "protected objects" and that includes players, VRC UI, and anything else that you don't have access to. OnEnterTrigger will hit one of those objects and then if your script tries to do anything with them, it will crash the script

all you need to do is if (!utilities.isvalid(target)) return;

[last swift]

so that line of code would be the first line nested in my if statement?

[grand temple]

it would be the first line after OnEnterTrigger

you want to check if it's valid, and if not return immediately without doing anything

[last swift]

i see. It's giving me another error error CS0103: The name 'utilities' does not exist in the current context I got the same thing with spelling it as Utilities

[grand temple]

you might need to upgrade your SDK, this is a relatively new feature

[last swift]

i have version v0.19.8, I believe that is the latest version. I will check real quick though

it appears to be the latest version

I just realized you were probably referring to the VRCSDK right?

I got the VRCSDK3 about a week or two ago so I'm not sure if anything has changed

[grand temple]

probably missing a using then, idk which one and I can't check right now

[last swift]

alright no problem, thanks for the help. Maybe when you get a chance you can message me about that. I would appreciate it

[floral dove]

a couple of things:

1. the Utilities class is in VRC.SDKBase so you need to import that or fully qualify its name: VRC.SDKBase.Utilities
2. The method is IsValid, check your capitalization.
3. If you're going to use U#, you will make your life a lot easier by setting it up so you get intellisense / autocomplete etc depending on your IDE. I can't help you set that up but you can find the UdonSharp wiki in the pins on this channel where you can learn more.

[broken bear]

if a gameobject with an udon script is disabled in the hierarchy when upload, but is toggled on while live, does the udon behavior get ignored? for instance a simple station that starts disabled

[floral dove]

No, the UdonBehaviour should work once its GameObject is set to active

[last swift]

@floral dove thanks a lot, the capitalization seems to have been the issue. I'm still lost with my code though because the collision between my asteroids and the catcher isn't firing or something. The asteroids should Destroy but they pass right through.

Here is my code on collision. The asteroids box collider is set to Is Trigger as well

[grand temple]

no, the isvalid check needs to be the very first thing

because if it hits an object that is not valid, and you try to check the name, it will crash immediately

so you need to check isvalid first before ever doing anything with the object

[last swift]

If this code looks correct now then it still hasn't fixed my issue, the asteroids still proceed through the asteroidCatcher like before

I don't think the script crashing was ever an issue, it's just not working when they collide. Not sure what's going on with it

[grand temple]

use Debug.Log(target.gameObject.name); to see what is happening

[last swift]

I did something similar Debug.Log("collision detected") when the trigger should go off and I'm not getting a message so it's just not picking up the collision. I look at the asteroid prefabs when they instantiate into the game and they all have the right script on them with a box collider that is set to Is Trigger. I'm not sure why the collision is not being detected

[grand temple]

does the moving object have a rigidbody on it?

[floral dove]

sounds like your scene and object setup is not quite right. Make sure at least one of your objects has a rigidbody on it

https://docs.unity3d.com/Manual/CollidersOverview.html

in this case, probably not your Trigger object

[last swift]

yeah the asteroids have a rigidbody on it

the asteroids have the Trigger

[grand temple]

but does the asteroid catcher have a rigidbody?

[last swift]

no it didn't but I just put a rigidbody on it and the same thing happens

[grand temple]

is asteroidcatcher an istrigger collider?

[last swift]

no the asteroids are set to Is Trigger collider

I have Is trigger set on the asteroidCatcher collider now too and the same thing happens

collision detection on all objects are set to Discrete, maybe I should try Continuous or something?

that didn't work either

[grand temple]

you're checking rather quickly... what exactly are you doing? Are you staying in play mode this whole time?

[last swift]

yeah, I'm using the CyanEmu.v0.3.5 unity package that allows you to run unity and test out features like being in VrChat

[flint urchin]

Be aware that CyanEmu is not meant to be used as a replacement for in game testing. It’s a prototype usage tool.

What you see happen with CyanEmu might not be the same as in game

[last swift]

alright thanks, but I feel like the collision detection should still be working for me. Should I upload the world to find out for sure?

[flint urchin]

You can do a test build yeah.

But if collision/trigger doesn’t happen with normal unity stuff (that doesn’t involve the player itself) then the setup/script has errors

[grand temple]

if you change a script and then test it without getting back out of play mode and coming back in, it's not gonna work

you need to start fresh whenever a script compiles

[last swift]

@flint urchin yeah that's what I'm thinking too. I just can't figure out what the issue is. Everything seems to be setup correct, but apparently not

[fickle bison]

hi, i wanted to ask you if you know how to solve the error that comes out of disconnection seconds after entering vrchat, it is not a Wi-Fi issue I'm sure but it still keeps me going I hope I can play it, it's nice (i start today)

[last swift]

@grand temple yeah I've been stopping it to make changes and then running the test mode again

[floral dove]

this channel is for questions about our programming language Udon - check #faq to learn where to ask different questions in this Discord. Cheers!

[fickle bison]

sorry

[limber jackal]

On the VRChat docs, I found this for the way to transfer ownership. Does anybody know how this is done in UdonSharp or if the feature is supported? It doesn't appear to be an available override.

And is there any difference about the behaviour of Network.SetOwner(...) and VRCPlayerAPI.TakeOwnership(...) ?

[stark adder]

@limber jackal you are reading Beta Networking

But anyway yes there is a way and I don't think there is a difference

Also SetOwner works on Live ofc..

[limber jackal]

gotchya. thanks that's very helpful

[last swift]

So in Unity play my asteroids spawn in but on VrChat the asteroids don't spawn in. I wrote the logic in U# so I have no idea why it's not working

[limber jackal]

Its been a while since I checked, but last time I checked, objects spawned during networked events had strange issues. An alternative might be to use object pools, or have all asteroids spawned in to begin with and they teleport to the spawn position as needed

[last swift]

I'm starting to wonder if maybe I'm using a few methods not supported by udon, I'm not sure though. For example, I'm using Random.Range to generate a random number, is that how you would do it in U#?

could someone check out my code and see if it conforms?

these are the scripts I'm using for the asteroids to spawn and move respectively. I'm wondering if I'm doing something not supported by Udon or something. btw I couldn't really figure out the object pooling functionality yet so I'm putting that on hold for now. I just want it to work on a basic level first

[last swift]

There's not much code between those two scripts and they're laid out pretty simple so it won't take up much of your time if you decide to take a peek

[floral dove]

You might try the U# resources, there's a Discord from the wiki

[last swift]

@floral dove I'm sorry but I'm not sure I understand you. I can't find a wiki for U#

[floral dove]

Check the pinned messages in this channel

[last swift]

@floral dove thanks I appreciate the info. Those resources should be a lot of help in the future, however I still feel like I'm not seeing documentation or examples for some of the code I'm writing and to know if it's compatible or not. I will spend more time going through it though and maybe something will help, thanks again

[floral dove]

There's a Discord where people discuss U# code, you might have better luck getting eyes on it there.

[last swift]

Alright thanks, would you happen to know the name of the server?

[last swift]

Nevermind I think I found it on the wiki. Thanks for your help Momo

[last swift]

does U# have issues with Vector3 positions? Instead of setting up a new Vector3 as (spawnPoint.x, spawnPoint.y, spawnPoint.z) I hard coded the coordinates and the asteroids still spawn in the wrong location, probably at 0, 0, 0.

I have the asteroids spawning in but they aren't at the gameObject I set as the spawnPoint, however when testing in unity it works fine

[chilly crater]

Are you not supposed to move all of the SDK stuff into a different folder?

[cunning mist]

nope

[chilly crater]

That's where all my issues came from.

Yerp, I did that and immediately thought afterwards "I wasn't supposed to do that..."

[last swift]

hey @cunning mist I've seen some of your videos and found them very helpful, keep up the good work. I was just wondering if you might do one on object pooling in U# at some point

[cunning mist]

Thanks, and certainly. Object pools are natively supported with a provided component in the UnU patch, so I will be going over that system when released rather than showing off how to develop one from scratch. So basically, pray that UnU comes soon haha

[last swift]

I'm praying lol, thanks

[true ocean]

hi, does anyone know how I can set an object's owner when it is picked up to the person that picked it up?

[hushed gazelle]

Does anyone know what causes the audio glitch that makes sound seem like it's all coming out of one ear, or a person's talking right next to you even when they're across the room?

[dapper lion]

that doesnt sound like a glitch but a weirdly set audio source or someone made a walkie talkie

[hushed gazelle]

No, it's very much a thing with Udon worlds.

[dapper lion]

exactly

it not a glitch

[hushed gazelle]

Except it happens with player audio, not sounds.

[dapper lion]

correct

[hushed gazelle]

It's very much a glitch though, as it just leaves the player audio perpetually broken until you reload the world.

[dapper lion]

ohhh the weird lapse thing. thats a layering screw up that can be done via avatars actually. im not sure why people perform this but its technically I guess 🤔 a glitch

but its also a normal behavior if the layer of an audio matrix is disturbed in a awkward way

cancels the mixed channels and requires a reset since nothing is updating the lost channel

[hushed gazelle]

What exactly would disturb that layer?

[dapper lion]

freaking siren in my left ear

im not exactly sure. could be a fire limit on left or right ear. could b a sound file that just doesnt play correctly like an ogg. or its a rapid fire audio source

you can technically perform this glitch on a world too by having 8 audio sources and have them play 8 different files, and replay them every second

but at the same time— its not technically a glitch since this is supposed to happen for hardware reason

[hushed gazelle]

Is there a format less likely to cause it than .ogg? mp3, wav, etc?

[dapper lion]

unity will default any audio file as ogg. so technically no. the practice is: just be careful

[hushed gazelle]

Does the VRC Spatial Audio Source component help mitigate it at all?

[dapper lion]

on my marimba world. theres 122 audio sources. and if you play a note fast enough. itll get quieter and sometimes completely break world audio. but since worlds have a refresh for its audio channels. it usually fixes itself. and vrc spatial audio source i think is used to do that weird trick where youd get a siren in 1 ear and its super annoying

so youll go to a party or some busy world and some source will be set to stereo left. and itll move that 1 audio to the left ear

[hushed gazelle]

World audio isn't the issue here though, it's the bug that causes player audio to sound like it's coming from the wrong direction.

[dapper lion]

player audio can be manipulated via udon— so i could make the stereo values inverted if i wanted to

[hushed gazelle]

Yeah, it's not caused by an erronious audio source.

[dapper lion]

theres a “betteraudio” github page that goes over a lot of audio and player voice editing and audio matrix bug fixes

ah. i thought you were talking about that stupid left ear siren trick people have been abusing the heck out kf

[hushed gazelle]

Nooo. I'm talking about the bug where suddenly people start sounding like they're either talking right in your ear or across from the opposite side of the room despite being next to you.

[dapper lion]

thatd be a weird bug. id canny for it. but its technically a possible thing you can script

[stoic mountain]

how can I figure out if a local VR player is pointing finger, or at least which buttons are being touched (not pressed) on its controllers ?

[cunning mist]

That should be happening natively for synced pickups, so you shouldn't need to set it yourself.

[true ocean]

ah yeah I managed to get it working now, your tutorials are super helpful btw ^.^

Is there an easy way to sync spawned objects for players?

[floral dove]

[leaden matrix]

what's UDON?

[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

[hoary echo]

Is there a way to make debug.drawline visible in the VRC client?

[native estuary]

Debug.drawline is only for in editor, use LineRenderer instead

If it's exposed in udon

[lost lake]

how i get to vistor rank

[rough geyser]

So I'm working with UdonSharpPlayer, but for some reason the drop down menu for UdonBehavior (Where the link to play is) has suddenly stopped working, anyone have ideas why this might be? https://i.gyazo.com/thumb/1200/b7f0bed6bf10e3eb0110ff8517c70eaa-png.jpg

Reimporting doesn't change anything either.

[dapper lion]

does sdk panel still function? try compiling all udonsharp scripts

[rigid plume]

Is the world components whitelist a bit out of date? I added some new Udon-powered jetskis to my world and needed to adjust the friction to them. It turns out the way to do that was with Physics Material components. The whitelist doesn't have those, but on a whim, I tried adding them in anyways. It turns out it works just fine for both Quest and PC, even though Physics Material isn't on the official whitelist. Weird...

[dapper lion]

those are like: “given default components” that just work no matter what

[rough geyser]

I was able to compile the scripts, but I still get nothing when I try to open the dropdown.

[rigid plume]

oh, ok.

[dapper lion]

@rough geyser try close and reopen

[rough geyser]

Hm. Still didn't fix it. Odd. I'll see what I can tinker with here, probably something Unity-being-dumb-relating.

[dapper lion]

what happens if you put a new GO with a UB on it? does it still act weird?

[rough geyser]

Testing.

[unborn hornet]

Ask in #vrchat-general-1 or #vrchat-general-2, This channel is for Udon discussion/questions specifically.

[chilly crater]

Do I have to use the network to set animation controller parameters?

[last swift]

what's also weird, in the Unity test run I go to the Scene view and look at my asteroids and Spawner and their transform is set to the same position but the asteroids are a lot further back. the transform coordinates are the exact same though. the asteroid spawn position is at (-76.6851, 2.858137, -27.64999) as well as the Spawner position, but when I move the Spawner back to the asteroids it has a positon of (-128, 7.023, -42.523) I wonder what is causing it to be off like that?

[chilly crater]

that's local/global position

are any of them children of anything?

[rough geyser]

After much moving stuff around, suddenly it begins working again, @dapper lion. No idea what happened at all ._.

[last swift]

the Spawner is a child of a gameObject that's positioned on the edge of my base

[rough geyser]

Although now I'm getting a thing on the second video player I have saying something about "Rate limit achieved, please try again in a few seconds". Time to tinker, I guess?

[chilly crater]

The position of children gameobjects are relative to their parent.

A quick hacky way to get around that ifyou want the same positioning is to unparent the object in the hierarchy, set the position to where you want it and then parent it to where it is supposed to be.

[last swift]

alright thanks

[rough geyser]

Actually, @dapper lion, you may know the answer to this. If I wanted one video player to synchronize toggling on with a trigger to a singular player, and not anyone else, is there a way of doing that via the Udon behavior?

[dapper lion]

theres tons of ways to sync stuff up but i highly suggest using a videoplayer that has a syncing feature already added to it

[rough geyser]

Well, actually...

I should probably be a little more specific about what I meant by "Sync"

Sync as in, a player walks through a collider trigger, which enables the video player and disables the other one in the other room. How do I prevent this change from going through with other players too, or is this not a possibility on a basic level? (I don't quite know Udon Sharp that well! ;w;)

[gentle tulip]

change it to local some way?

[rough geyser]

Well I know that a lot of the Udon Behavior stuff can be used to simply "Synchronize" the position of an object, (ETC. Mirrors, from a UI) but the player doesn't have just a straight "Synchronize position" toggle, I'm assuming because of UdonSharp and how it was coded.

Again I sadly have very little Udon Sharp experience, so I mean, yes it's time to learn but eck ;w;

[dapper lion]

oh so it like turns off and on depending on distence?

and then resync the video globally when its turned on locally?

it should be too hard. have a script that waits for a person to enter a collider wall that triggers the sync-videoplayer and that should work. just make sure the scriot doesnt disable when person leaves collider

[rough geyser]

Hmm.

Yeah, it basically turns on and off for the players independantly when they walk between the rooms.

[rough geyser]

Would changing this perhaps do that? https://gyazo.com/d05d56f0ad474d6f7542595df33d885a

Only checking, because again, bad

[dapper lion]

thats how the video player checks to make sure people are synced up iirc

[rough geyser]

Eh, fair. Figured that was the case.

Time to go dig into C#

[scarlet lake]

my old and first project was ripping 40k frames to unity and converting them over to sprite UI, which i then threw in animation and scaled it by speed.. created a video out of sprites.. perfect quality and didnt weigh that much.. was synced to everyone too.. was just a silly experiment really.. but it worked quite well considering.. lol

[dapper lion]

bruh.. i mean if it worked—it works lol

[scarlet lake]

Pffs who needs video players.. sprites are for life.

[dapper lion]

that sounds very time consuming unless you had a bot or something do that for you

or maybe theres something secret about sprites i havent figured out

[scarlet lake]

no it was time consuming it took me about 4-5 hours.. but like all my projects.. they take my time but its worth it for the experiment factor.

Plus.. never really know how it could be used.. though had some idea's lately with udon and ripping frames.. need a controller and should be able to get pacman easily up and running.

[dapper lion]

lol thatd be cool

[scarlet lake]

There's not much secret in sprites.. though im sure there's more to learn.. my latest funland i build for quest users is going to be released soon.. 16 rides and only 20mb.. i built the entirely of it mainly out of sprites and low poly models.. yet i also used C over to U# and created a material switcher on script 20mat changes per second.

Does not create any lag at all.. the entire map runs without bake and no lag.. had testers on it already.. there is no lights sources such as directional point etc.. i have everything lit with bakery/lit to do transitions of switchers.. i have practically a Funland at night lit up like 80's neon everything and it runs beautiful. i also turned off all shadows and all reflections.. and optimised it beyond the normal..

I figured it would weigh less sure but i expected to hit 50mb cap but when i saw my build uploaded at 20mb what can i say.. just beautiful man honestly lol.

[dapper lion]

20 mb is beautiful

my latest world is half finished and it already hits the 50 mb limit easiely lol

[native rampart]

is there a local-only version of TeleportTo?

(or is it already local-only, I actually haven't tried yet)

maybe more generally: does anyone know how that world built on the inside of a cylindrical space station works

(I can tell that it's moving the world around the player, but I don't know how it moves the other players separately...)

[floral dove]

No such thing - Avatars are synced automatically

[native rampart]

hmm, ok

and no way to access the game object, to change what it's parented to?

[west mural]

only way to desync player positions is using stations

[native rampart]

which would prevent them from locomoting around, right?

[west mural]

no, you can set them to be able to move

stations have a tickbox for immovilize

[native rampart]

oh huh!

maybe that's how it does it -- the world DOES start with having to click a 'start' button

so, I'd been thinking of stations as only chairs

but is a station with mobility enabled, basically for like, a train car?

so you can walk around inside of it while it's also moving you around in the world

[chilly crater]

Are animator controller parameters synced?

In world.

[formal leaf]

guys how do i make my VRC Pickup thing respawn after it falls off the world

[fading cipher]

Hey all, why can't I switch to Android? https://i.imgur.com/mEGQc6D.png

[dawn forge]

May not be your clear answer, but here is what I am doing when my pickup falls off the map or is too far from its pedestal/spawn

This is UdonSharp(U#) I don't do graphs, so somebody will have to show the meat and potatoes of the graph to do what you want.

    /// <summary>
    /// Check if the flag is wayyy too far from the map. Define the distance by measuring from the pedestal to the "edge" of your arena, NOT the scene.
    /// </summary>
    private void RespawnFlag()
    {
        if (Vector3.Distance(this.transform.position, FlagPedestal.transform.position) > 10.0f )
        {
            // Put flag back at the pedestal. TODO: Orient flag to pedestal appropriately.
            this.transform.localPosition = FlagPedestal.transform.position;
        }
    }

That is being called by a fixedUpdate on the object.

[grand temple]

that code can be used to make something respawn if it gets too far away, but just respawning when it falls off the world is something you don't need to code to do. Anything that has "sync position" checked on the udonbehaviour will have that

[chilly aspen]

I have two game objects each with an udon sync variable. Do the sync variables always do PreSerialization in the same order at the same time, or is there variance? For instance, is it possible for one of the objects to execute more or fewer PreSerializations than the other object?

[chilly crater]

If I have an UdonBehavior set an animation trigger, do I have to send it as a network event to be synced?

[chilly crater]

SyncPosition does that? I thought that was the scene descriptor.

[fiery yoke]

Ofcourse the synced position behaviour is responsible for respawning/resetting a synced objects position. It just gets the world height from the descriptor.

[formal leaf]

Is it possible to make it so that not all players are loaded at the same time in a world? like, can u make it so that avatars will only show when their within a radius of you or something?
(Like, with world settings or something like that)

[broken bear]

will synchedposition automatically be updated to the unu to show late-joiners the position?

[normal swallow]

Not sure if something changed but now whenever I build my project it doesnt keep the changes i made to the interaction text portion of my Udon behavior script (on an avatar pedestal)
Is that something anyone saw before?

[stark adder]

What do people do to invalidate SendCustomEventDelayed ? 🤔 I am sending an events through multiple frames and I want to invalidate all previous ones only keep the last one 🤔 I saw using two ints it could be possible 🤔 any other ways anyone though of ?

[void ridge]

https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback/p/1065-feedback-add-a-way-to-invalidate-delayed-events

[stark adder]

Yea I saw

[rigid plume]

Anyone know how to prevent a VRC_Pickup controller for a vehicle from lagging behind its vehicle at high speeds?

My vehicle consists of the vehicle itself and some child objects: VRC seats and a VRC pickup which functions as a controller. While held, the player can hold the trigger on the controller object to steer it left or right or throttle forward or backward. At high speeds while it is held, it starts jittering or lagging behind 1 frame.

Not sure if there's just some simple setting I'm missing here...

controller settings^

[dapper lion]

sometimes the children with synced position will lag behind because the main parent will already be set to sync position

[rigid plume]

Should I try unsyncing the controller's position?

[dapper lion]

if its parent is set to sync. id try unchecking the sync position on its child if they are not already

[rigid plume]

ok, I'll try it out.

That didn't fix it, unfortunately.

[dapper lion]

hmm. im not sure then. maybe its a rigid body thing but thatd be a bit weird if its attached to the vehicle

[rigid plume]

The weird thing is that if I let go of the controller while going at high speed, it follows along with the parent vehicle just fine, without any jitteriness.

[sand lion]

umm whats udon

i feel so dumb

[fiery yoke]

?whatisudon Youre welcome @sand lion

[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

[sand lion]

ty -w-

[rigid plume]

I think I found the solution to my problem. It was nothing to actually do with the controller. The problem was the seat. I changed its Player Mobility property from "Immobilize" to "Immobilize for Vehicle" and now it controls much more smoothly.

[stark adder]

How can I force custom startup parameters to Build & Test ?

I put them in so many places none of them world

[fiery yoke]

Pretty sure you can only do that with a custom bat that you set the startup path to

[stark adder]

🤔

What should the startup bat look like if I want the startup to work and non-vr checkbox to work too

[fiery yoke]

I dont really know anything about bats (neither in programming nor in biology lol) I used one that looked like this

@echo off
if not DEFINED IS_MINIMIZED set IS_MINIMIZED=1 && start "" /min "%~dpnx0" %* && exit
cd %~dp0
VRChat.exe --enable-debug-gui --enable-udon-debug-logging --profile=1 --no-vr
exit

But thats very over enginereed lol. I tried automatically minimizing the command prompt window

[scarlet lake]

There's this guy that was flying around and said he was a Admin and he could ban People so i have a question? Can Admins fly?

His name was something like Zzero but i cant remeber the rest

[stark adder]

That doesn't start the test worl though

[fiery yoke]

Yeah it does not. I manually joined my test world. You gotta adjust the launch parameters.

[stark adder]

How can you even join the test world though ?

YOu can't join it though

[fiery yoke]

Ohh yeah I used that for uploaded worlds

Youre right I forgot about that

[stark adder]

ah

[fiery yoke]

There is a way to do that I think...

But I dont know sorry ¯_(ツ)_/¯

[stark adder]

@echo off
VRChat.exe --no-vr --enable-debug-gui --enable-sdk-log-levels --enable-udon-debug-logging %2

endlocal

And doesn't work Starts up VRC with these params but doesn't go into the test world

[fiery yoke]

ohh yeah

I remember that now

VRChat is weird

they dont fully expose all the stuff that is necessary to define an instance

[stark adder]

So what you need to do then

[fiery yoke]

No idea. I just uploaded everytime I had to do something with multiple clients lol.

[stark adder]

.. Uploading is taking fucking 10 minutes..

Build and test takes 2

[fiery yoke]

Maybe someone else knows. I dont sorry

[stark adder]

VRC stupid

[fiery yoke]

I mean maybe it is possible. Just some...documentation on that would be sweet. You know ¯_(ツ)_/¯

[stark adder]

Documetation

[unreal grail]

How can I force players to respawn with Udon?

[fiery yoke]

Guess what again: You cant.
You can only teleport them to the world spawn (which is effectively the same as respawning)
There is some gotchas to that as well as always tho

[unreal grail]

How do I do that? Since you can't teleport other players.

[fiery yoke]

Ohh yeah. Right. You could send a custom event to the owner of an object, or all. But that doesnt really help you I guess. So yeah.

[unreal grail]

So the question again is: how is it done?

[fiery yoke]

Depends on what exactly you need.

[unreal grail]

I need to respawn all players in the instance.

[fiery yoke]

You working with a graph or U#?

[unreal grail]

Either, so long as it works.

U# preferred.

[fiery yoke]

SendCustomNetworkEvent("RespawnAll", All) => Respawn: VRCPlayerApi.TeleportPlayer(Networking.LocalPlayer, worldSpawnTransform)
Something like that

[cunning mist]

I actually just did a tutorial on SendCustomNetworkEvent. If you want to, you can just swap the object toggle event for one that teleports the local player, and forgo the late-joiner networking. I posted it in #udon-showoff

[fiery yoke]

Im also confused on why TeleportPlayer even has a player api parameter

if you cant teleport any other player than local...

[cunning mist]

A large portion of VRCPlayerApi events don't work on non-local players. Attempting to change a different player's walkspeed, for example, just breaks entirely.

[fiery yoke]

Yeah. Confusing if you ask me.

[unreal grail]

I don't have TeleportPlayer available under VRCPlayerApi

[fiery yoke]

ohh yeah sorry its called TeleportTo

[unreal grail]

The one preceded by an underscore?

[fiery yoke]

Ahh okay no. Its an instance method. Havent used them in a while.

Networking.LocalPlayer.TeleportTo() I guess

[rigid scroll]

Is there any way to drive custom script data from within uson?

I currently am working on a commission and the client wants randomly moveing tail which would require some custom scripting.
My goal would be to drive variables from my dynamic bone component based on that. Is that possible?

[dapper lion]

on avatars no. but on worlds—technically

you can probs just set up a long animation that seems random

[rigid scroll]

Is there any way to do this sort of custom scripting for a character? Are there alternative solutions to randomly move bones?

[edgy ingot]

use a 2 axis blend tree, tailX and tailY, use an animation that changes a value that's valid but does nothing in your avatar (I use material values i'd never use) and use those as a "timer"
then go from "timer state" to "change state" and in the "change state" use the behavior "VRC Animator Parameter Driver" on the state and have it set the tailX and Y to random values
adjust the timer to taste and use dynamic bones to smooth out the rest
that's on the avatar side, so more #avatar-help but it's an idea

i did something like this for a friend's avatar with their eye color

but this is on the avatar side, i dont think Udon can force avatar parameters

[rigid scroll]

Thank you! Sorry for asking in the wrong chat.

[edgy ingot]

no problem, if you have any questions on what i said feel free to ping me in #avatar-help

[atomic bone]

hey! how do i do arithmetic in Udon? like take the difference of two of my variables?

found it nvm! under the primitive types

[fading cipher]

Is there no way to specify which object you want to call SendCustomEvent on if you're calling it with an animation event?
Because right now it just calls it on all parents/children within the gameobject's chain and I'm trying to only call it for a specific child

[atomic bone]

what's the best practice for doing the equivalent of logging values to console in udon to test in game?

[abstract mesa]

so random question but is it possible to set a texture to scroll along a given axis in a world? I feel like it should be possible but I'm quite a baby when it comes to udon so I'm not sure of its limits

[fast prairie]

Are there ways to catch errors? an odd edge case I cannot replicate appears sometimes. Thought I was okay with the if(player != null) but GetBonePosition in the brackets 'hits the fan'

[unborn hornet]

There is no exception handling in Udon currently. To check if a player actually exists, use Utilities.IsValid(player) instead of player != null

[fast prairie]

aha. this also applies to a list of players populated with VRCPlayerApi.GetPlayers U# ? I was warned from using this so maybe my own fault

[unborn hornet]

Yes the IsValid method was developed in-part with the GetPlayers functionality in mind.

[fast prairie]

I'm thinking now it could be a timing issue so that would make sense for it being hard to reproduce. Thank you muchly

[flint urchin]

It’s the same method used by moderators to teleport players in game afaik

[flint urchin]

Yes and you would do it in a shader and not specifically in Udon

[abstract mesa]

Ah I see. I know it can be done shader and is likely the best way, I was just hoping there would be another method because I honestly am not much in the mood to go fiddling with shader code again. because I'm gonna need to make it scroll and be a fade texture which I don't even know how to begin with.

[last swift]

I'm working on an in-game joystick that a user can interact with. I put the VRC Pickup script on it and I set orientation to Grip, and Pickupable to false. Now I think I might need to write my own custom script to get the joystick to actually move/rotate with the players hand motion. Does anyone have an idea on how I could do that?

[fair terrace]

the ultimate limit of 80 people in one instance, is it possible to get experimental/temporary lifting of that limit on a world?

[stark adder]

There's 82 people max from what I know

[grand temple]

owner of instance and author of world can bypass the hard cap, yes

[stark adder]

And having stable 82 player instance.. GL HF

Though I heard someone saying devs had some kind of test or what with more than 80 people ?

[grand temple]

yeah, it got up to 130 ish people. Definitely not a normal thing, don't expect to ever see that happen again

it was far from a usable experience though

despite everyone using avatars that were literally just a single white quad

[stark adder]

I really wanna see 500 people in instance lol

[flint urchin]

Only if the instance is already full, it does not make the instance +2 if they are already in there

[grand temple]

yes, exactly

[stark adder]

Lol

Mute every single person there and ez

[halcyon falcon]

what is udon like? Javascript is what im most familiar with so i wanna know if theres any other code languages i might have to learn, or is it comparable to simulink/MATlab code?

[grand temple]

it's most similar to C#

Because it's based on unity monobehaviours

and most of the unity documentation and questions about monobehaviours will also apply to udonbehaviours because of that

[halcyon falcon]

does udon work well on quest 2 yet? Unsure if i should use it/learn it in my first attempt of a world or not

[grand temple]

yeah, totally

udon has worse performance than native unity code but it can still perform plenty if you're careful about how much you put in the update loops

[halcyon falcon]

eh probably wont do anything too crazy, At most this world is gonna be personal so i dont wanna worry too much on performance yet

[hybrid pivot]

hey can i ask questions for vrchat here?

[rotund wraith]

yeah

[hybrid pivot]

thanks

[rotund wraith]

noice

[hybrid pivot]

i cant seem to add my friends

i just started this game

we can search and find each other

but we dont receive the invite

[rotund wraith]

thats weird...

but, why don't you just click join under his/her name?

[hybrid pivot]

how do i do that

isit becuz i have to be higher then the visitor rank or something

[rotund wraith]

no, there should be a thing in your menu saying smth with social. click on that, find him, friend him by seaching on him, if you haven't already done it. then click on him, and then theres a button where it says "join".

[hybrid pivot]

How do I accept request

[rotund wraith]

on social too

it should pop up under requests

[hybrid pivot]

yea thanks

it worked

it was bugged before

[rotund lion]

I've been trying to do an udon graph that compares the states of 4 objects and if they are all equal to each other, set the object on the right's state to on/off accordingly, New to udon so I think I'm using something wrong but any help would be really appreciated.

[mighty fjord]

Should probably switch out those boolean Equals nodes with boolean Equality nodes

[rotund lion]

for future reference what's the difference?

[mighty fjord]

Actually, do you want it to go through the branch when all objects are off and on, or just when they're on?

[rotund lion]

Just when they're on

[mighty fjord]

Then I'd suggest doing Conditional And nodes instead of the Equals nodes

Otherwise if all the booleans are false, they'll all be the same, and thus letting the branch go through 'true'

[rotund lion]

Ok so just to make it clearer on what I'm trying to accomplish I'm trying to make a prototypeish version of a map so I have all the udon stuff to use as a cheat sheet. The one function that's giving me the most issue is my lever code kind of thing I have.
