(Time to entirely re-write my join game logic now.)

#

Trying to make a ui slider that changes the intensity of a light. This doesnt seem to be working ?

#

wait

#

give me a minute

#

yeah no i cant figure it out

sharp briar
#

So the documentation for audio says that SetAvatarAudioFarRadius and SetAvatarAudioNearRadius set to 0 would effectively mute avatars, but it only seems to work for your own avatar not others avatars

There's a pretty helpful example script in the SDK examples, which comes with the SDK. Just search for it, it's called "SetAllPlayersMaxAudioDistance"

#

still at it?

#

lol I was just saying I see you in here like every day

void ridge
#

time is meaningless

"what is day?"

I got animations working

Is it possible to change the bone used or interact with that tt input? I've tried everything but nothing seems to work.

gusty garden
#

It does, but I was wondering how I could change that with the tt input. I wanted to reuse one script on multiple bones instead of making a seperate scripts for all of them.

void ridge
#

I see, yeah. I'd like to know the answer to that one too

fiery yoke
#

The enum is called HumanBodyBones

#

no idea why the input is called "tt"...

Thats all I see searching for it. Assuming I am missing something?
Op nvm, ive figured it out.

#

I have, on player stay connected to avatar near, far and gain all set to 0

#

Theyre connected with the main noodle as well as to the instance ones

#

It all seems to work but only for the player using the audio

#

They can't hear their avatar audio anymore

#

But other players can hear it no problem

void ridge
sharp briar
#

Yes

#

Give me 2 mins and I'll get the graph I used

void ridge
#

Don't worry about it for now

#

I've got good news and bad news. Bad news is, I don't understand why this doesn't do what you want. Good news is, I can help you improve this in ways you might not care about, but I do 😅

sharp briar
#

I've tested with global audio and regular avatar audio and it mutes the audio from yourself but doesnt do anything for other players avatar audio

wet mica
#

damn, ive been programming for most my life so if i were familiar with the software id be able to help out

void ridge
#

My understanding of the OnPlayerTrigger events is that they should be executed locally for everybody running that UdonBehaviour, which should be everybody connected. They're not explicitly 'synced,' but all player positions are automatically synced, so a player colliding with the Trigger should be an event that happens globally, in effect.

#

So I would expect what you have to be working, and if you learn why it isn't, please let me know!

sharp briar
#

Like I said earlier, I have a similar graph that just boosts player audio and works perfectly

void ridge
#

..but while we're waiting, three tips:

  1. You'll save some (probably small) amount of performance resources by using an OnPlayerTriggerEnter node instead of OnPlayerTriggerStay, which executes every frame
  2. It seems like you want this player to stop being muted when they exit the Trigger, right? If so, you're going to need an OnPlayerTriggerExit node to set their audio properties back to normal
  3. I'm pretty sure you only need to worry about SetAvatarAudioFarRadius. Setting all three of these to 0 is redundant
sharp briar
#

I dont want to reset the values

#

I dont want players avatars audio on my map at all

void ridge
#

Oh. Then why not just use OnPlayerJoined?

sharp briar
#

I thought of using the thing that applies it when you join

#

But it didn't seem to work at all?

#

I can try that

#

I mightve done it wrong the first time I tried

#

I only did all 3 as a nuclear option cause nothing was working

void ridge
#

OH, wait a sec. I think maybe I know what the issue is here

#

Players who join after a player has touched this trigger will never execute an event that lowers earlier players' volumes.

#

This might also explain the inconsistency you were seeing. With the voice boost script, you were probably the early player to join, and saw later players' voices boosted. But in this case, you're joining late, and you're not getting the update.

#

This is what I use to set players' audio in my World. I'm .... pretty sure it's correct? 🤷‍♀️

📎 unknown.png
sharp briar
#

Sorry I looked away for a sec

void ridge
#

The top part essentially says "Welcome to this World instance, here's a list of all the players already in here, and I will now tell them all to shut up"

#

The bottom part says "anyone that joins after you, I will tell them to shut up"

sharp briar
#

I'm the earlier player for either the player audio and the avatar audio thing but in my testing I get similar results for myself and the other person helping me test

void ridge
#

Try out what I put above and see if that works

#

If you want to understand what the first few nodes are doing, check this out:
#udon-general message
Momo explained it to me mere days ago 😅

sharp briar
#

Momo is gr8

#

Momo helped me with my initial player audio tho I think I kinda went off the rails a bit

#

It got me to where I wanted

#

I can implement this right away but I won't be able to do proper testing till later tonight

grand temple
#

@void ridge doing that on start isn't going to work, it's too early

void ridge
#

rakgakjhakhg

grand temple
#

But you're doing it all in onplayerjoined so that will work just fine

#

Because when you join a world that already has players, you still receive all the onplayerjoined events from them

sharp briar
#

So does like, a quarter of the graph work then?

void ridge
#

Is it just kind of a general bug that VRCPlayerApi stuff isn't determined until after Start events?

grand temple
#

Anything regarding networking will not be available on start because that's before you receive any data from the network

#

Start happens even before the fade from black, and if you have ever joined an instance with a bunch of people sitting around spawn, you will notice that it looks empty for half a second then all of a sudden they all pop in

void ridge
#

right, yeah.

grand temple
#

Also don't modify voice radius like that, it's an advanced setting that in most cases shouldn't be touched. It's not about range, it's sort of like the "size" of the sound. For example lightning will reverberate around and sound like its coming from everywhere

#

Oh wait I think I misread, you're modifying avatar audio that's fine

void ridge
#

Ohhhh, are you saying that OnPlayerJoined fires for each player that's already connected, as you yourself join, because it counts those people as "joining" even though you're really just starting to receive network data from them?

grand temple
#

Exactly

void ridge
#

OK, so I'll call that not super accurately named, but that's good to know

grand temple
#

If you just want to modify the voice of everybody in the instance permanently and you don't need to change it later on, that's all you need

sharp briar
#

So I just need that last bit of the graph?

grand temple
#

Yes

void ridge
sharp briar
#

Sounds goood

#

Thank

#

I'll let you know if it works out

So i'm working on a gun prop and im unsure what function i would want to call when a user clicks while holding, currently i tried Interact but that only seems to fire off once a user grabs the item.

vast locust
#

So in SDK2 I created a slider to increase the height of my gameobject (A cube as example) by using an animator & slider.
However in UDON this isn't working at all, Exact same stuff, But not working at all.

fiery yoke
#

UI Events are filtered in SDK 3. You can however use udon to achieve the same effect. However it is a little more complicated.

unborn hornet
fiery yoke
lethal helm
unborn hornet
#

You are looking at the raw asset. To do anything to it, you have to attach it to a game object first.

lethal helm
#

ah

vast locust
fiery yoke
#

instead of directly setting a value in the OnValueChanged event you do SendCustomEvent to the UdonBehaviour and then the UdonBehaviour reads the value of the Slider. Then you do whatever you want with the value inside of the UdonBehaviour.

#

Check for Networking -> get LocalPlayer and PlayerAPI -> IsMaster in your nodes.

#

IsMaster will output a bool on whether the passed in player (in that case, the local player) is the instance master or not.

Has anybody had an issue where in SDK3, if steamvr is running, every other test build will launch into vrchat desktop mode (and steamvr's desktop game theater)? "Force Non-VR" isn't checked.

serene moat
#

yep I've had that exact issue, the only solution atm is to keep your client open between build & tests

#

I hope someone knows a proper solution

dark raft
#

well, at least it's not just me.

fallen chasm
#

anyone have docs or info on detecting the local players avatar height?

unborn hornet
#

@dark raft untick this in the VRChat properties (Right click VRChat in your library)

📎 unknown.png
#

that should fix the issue

#

@fallen chasm

    private float calculateAvatarHeight(VRCPlayerApi player)
    {
        var head = player.GetBonePosition(HumanBodyBones.Head);
        var neck = player.GetBonePosition(HumanBodyBones.Neck);
        var spine = player.GetBonePosition(HumanBodyBones.Spine);
        var hip = player.GetBonePosition(HumanBodyBones.Hips);
        var knee = player.GetBonePosition(HumanBodyBones.RightLowerLeg);
        var foot = player.GetBonePosition(HumanBodyBones.RightFoot);
        var height =
              Vector3.Distance(head, neck)
            + Vector3.Distance(neck, spine)
            + Vector3.Distance(spine, hip)
            + Vector3.Distance(hip, knee)
            + Vector3.Distance(knee, foot);
        return height;
    }

Not 100% exact, but gets the job done pretty well.

fallen chasm
#

is that limited to humanoid avatars?

unborn hornet
#

Oh sorry that's U# lmao. For Udon Graph the nodes are pretty similar in logic.

#

Yea.

#

All bone calculations are humanoid limited

dark raft
unborn hornet
#

no choice on that atm.

fallen chasm
#

good info either way -- thanks Archi

unborn hornet
fallen chasm
#

suppose it's possible get the collider size?

#

~unless that blue pill is just a vrchat visual and not actually a capsule collider

unborn hornet
#

I'm pretty sure it's always 2m high, regardless? Not sure on that one though, just assumption based on observations when messing around in different avatar sizes.

#

But actually getting a direct reference to the player collider isn't possible.

fallen chasm
#

I'm not sure about that -- I've seen ants and pusheens running around that are difficult to target due to how small their pill is.

#

not sure about that size*

#

no idea about the collider -- that's why I'm asking here XD

unborn hornet
#

🤷 like I said, assumptions. Very well could be wrong.

fallen chasm
#

still, that script you shared should be useful -- I'd like to set up a node graph that raises and lowers a settings panel based on avatar height

#

might just be limited to humanoids

unborn hornet
#

Actually... now that I think about it... if the collider is a pill that is scaled based on the avatar height, if the local player's avatar is the only one who's height is actually calculated and applied to the pills, the fact that the remote player's colliders on the local player's client is only a sphere at their feet would 100% make sense....

#

Holy shit if that's it I just had an epiphany...

#

Sorry, tangent...

fallen chasm
#

O.o

unborn hornet
#

Then do node PlayerAPITrackingData -> get position

#

you can grab the Y axis off that vector to determine the height of the controls.

fallen chasm
#

is TrackingDataType.Head looking a a bone, or just tracking data? I know that's probably a really obvious question

unborn hornet
#

It's the tracking data position for the headset. The bones are not 1to1 mapped to the player tracking data. There are certain limitations for the bones vs tracking data.

fallen chasm
#

that's promising then -- I have a whole script that appends a target object to my player's feet, would be nice to append it to the "head" wherever it is.

unborn hornet
#

Yea, that tracking data head position is exactly that.

fallen chasm
#

hmm... gotta figure out how to convert tracking data to quaternion

unborn hornet
#

PlayerAPITrackingData -> get rotation

#

Multiply that by Vector3.forward and you have the direction the player's camera is facing.

#

Or if you just need the Quat, don't worry about that second step

fallen chasm
#

I think I'm set here -- gotta do a build/test to see

#

dang...

#

seems to only work with avatars that have a head bone, even as "tracking data"

#

but for headed avatars, it works great

#

oh dang, wait... I still have a 'get bone pos' in there

#

success

unborn hornet
#

Yea, literally everyone should have Head tracking data, even desktop.

fallen chasm
#

this works to append any object to the players head^ (ss replaced, look below)

#

if anyone else needed something like that

#

(head bone not required)

#

thanks for the help Archi

unborn hornet
#

You can use the same GetTrackingData output node for both rotation and position to save yourself 2 nodes.

fallen chasm
#

😮

#

you're right

unborn hornet
#

Nice. I'd recommend untangling the noodles a bit for better readability, but that looks good logically.

#

Unrelated to above. I think I figured out why the following occurs with UI elements:

📎 unknown.png
#

This occurs when the canvas that the UI belongs to is set to a Sorting Order of greater than 0. Anything 0 or less, the transparency renders correctly for the VRC UI Shape pointer.

#

Just in case anyone had issues with it.

For the topic about about the tracking, how would I set an object to not rotate downwards or upwards if the player looked up or down? I want the rotation to only be set for when the player turns their head left or right

something like base unity hase GameObject variable/class, only specifically for players.

@placid niche did you get it?

No sir

robust terrace

box collider, scale box to fit the object

@placid niche check dms

robust terrace
#

@placid niche Box collider 2D?

or just Box collider?

placid niche

box collider

robust terrace

ty! 🙂

placid niche

also make sure the object it's on has a box collider

robust terrace
#

@placid niche I must have done something wrong....the object is still not there.....the object is placed on the floor of a room, which I can walk on so I assume has a collider on it

make sure the item isn't static

@placid niche Sorry for another question, but, while I could build and run the world in local test mode, when I try to upload to VRChat and click the "Upload" button, nothing happens. Again, I've probably missed a step....

you've uploaded it previously?

it's probably just unity lag/delay

do i just add it to the bottom of the hierarchy?

then just make sure it's above the ground or people will spawn underneath your mesh

also right click the VRCWorld and unpack prefab

Supposedly udon doesn't like packed prefabs

unpack prefab completely or just unpack prefab?

#

@placid niche do the error messages mean anything at this stage?

#

was that project sdk 2 before?

placid niche
#

I..dont think so?

robust terrace
#

No...well, when I first started I installed the avatar SDK3, and then the world SDK3 on top of that, then deleted the folder on my D drive and re-installed the world SDK3 again....everything seems to work ok except for those error messages

#

I'm re-trying 🙂

#

Same error messages 😦

dawn oxide
#

I mean SDK3 and udon should never be in the same project to begin with. Sometimes folders from whichever one like to linger and so error messages get created. Create a new project with udon but do not put sdk3 into it

robust terrace
#

@dawn oxide So I should not use SDK3 at all for world creation?

dawn oxide
#

No because SDK3 has to mostly do with Avatars only while Udon is world creation only

#

But hold on though

robust terrace
#

@dawn oxide I am a bit confused....the VRChat website seems to indicate that there is an SDK3 for worlds.....the file I downloaded is called "VRCSDK3-WORLD-2020.12.09.04.44_Public"

dawn oxide
#

That is why I said hold on

#

So in your particular project, have you ever put in SDK3 Avatars before?

robust terrace
#

not in this project....I did in another one the other day, but that was separate

dawn oxide
#

Those error messages you are recieving in the console, have you clicked "Clear" to clear the console of any errors first? If not, any errors you had before tend to stay even when you upload. So you may not even have an issue to begin with depending on if you have already cleared it or not.

robust terrace
#

@dawn oxide Yes, I did clear about 5 minutes ago....but they came back....and now the upload button is not responding

#

I think i might start again using all the tips Nitro gave me....make a clean start

dawn oxide
#

Before doing so, I'm looking more closely on your picture and that screen is wrong, at least to my knowledge, because you never choose tags under content warning.

hmmmm....I don't have the "Publish to Community Labs" icon

this is a random world i was doing so its never been published. when you click on build, when this screen is loading do you happen to click publish right away or do you let it load?

robust terrace
#

ummmm....the only thing I click is "Upload" (other than "Public World" and "The above information is accurate and I have the rights to upload this content to VRChat")

dawn oxide
#

the reason why i ask is because for me, when everything is loaded up, i took a screenshot of what it looks like if i were to immediately try to publish

So maybe I need to just wait longer do you think?

perhaps. if not, i can call you in discord if you'd like and screenshare to help you out

So I've seen plenty of worlds with a moving platform that people can jump on, and I'm wondering if there'd be some kind if way to code in something so that when a player steps on it it carries them with it, by them inheriting the objects position over delta time added to their current position

zinc scaffold
#

Revisiting my earlier question, as I've gotten the chance to test:

  • How exactly do you sync variables in a way that lets anyone affect it? I've got OnDeserialization -> SetBool for the non-owner side, but it seems like I'm always the owner as the world host, no one else can do it
  • Also, how do you sync spawning pickups? A synced GameObject array?
chilly aspen
chilly aspen
# zinc scaffold Revisiting my earlier question, as I've gotten the chance to test: - How exactly...

For the first question, only the owner can directly manipulate the networking variable since all non-owners see what the owners see. To get other players to interact with that variable would require having the player inform the owner of a variable change and having the owner change the variable, or setting yourself the owner and changing the variable directly (higher risk).
For the second question, gameObjects should be pre-populated in the world before runtime. Spawning synced gameObjects during runtime has some odd glitches from personal experience. To create a synced gameObject array, sync the index of where each gameObject appears in the array (the owner of the gameObject would upload the correct data). When the other player gets that index, they put the gameObject in the array locally. Then, the array is synced.
If you'd like to sync more than just the gameObjects indexes in the array, then a networking variable would be created for each piece of information that is to be synced.

I have a gun like this in my world, and I would like to allow the player to hold the grip when he is holding the gun, and that the gun looks towards the grip.

I was told by some people in an rp I'm in that they use special script which I can't seem to find(most likely since they are not using udon, I saw couple of scripts missing in my project that udonless projects have)

I tried writing my own script, but it just doesn't seem to work.

What would be the best way to achieve that that works?

📎 unknown.png
#

also, it's hard to see on the screenshot, but I have a collider on the main handle of the gun(where it's trigger is), and I have an empty GameObject as a child of the gun, which is positioned where grip should be and it has a sphere collider

Hi, does anybody know a way to use "functions" or "methods" in Udon? I would like to avoid copy pasting the same graphs over and over. Very error-prone... :/

@quaint onyx Set the pickup

's orientation to be Exact Gun

#

Accidentally hit enter too early lol
But yeah, that will allow you to use the transform you've selected as "Gun" to tell it where to grab. You may need to wiggle it around a bit to get it into the right spot, but you can test that quite quickly with CyanEmu.

@outer shoal You can use SendCustomEvent to call an "Event Custom" method, though you cannot pass it variables or the likes, so it's a bit more limited than you're likely used to.

outer shoal
#

ok it's better than nothing. Thank you 🙂

#

If you had set it to be Exact Gun without placing something into the Gun slot previously, it may have gotten strange results. As well, you will likely just want to use the "Grip" item you have as your "Gun" location.

quaint onyx
#

I'm not sure you understood my question. You seem to be telling me how to grab the gun. I'm asking how to grab it with both hands, and that it looks towards the 2nd hand

paper plinth
#

idk if interact works like that...I don't think you can interact with one object with one hand and interact with another object parented to it with the other hand.

#

if it were two separate objects or hierarchies that are interlocked to each other's transform, potentially you could make them interact this way

cunning mist
#

Oh yeah, setting up two-handed grip isn't a native feature of VRChat and requires some weird setup on your side that I've never worked on.

hi there, i'm new to udon programming and searching how to instanciate a VRC_oscButtonIn in my world... i'd like to make a test using an external software to trigger an event in my vrChat world (let say i pressed a physical button to trigger an effect in vrchat)

Open Sound Control

Open Sound Control (OSC) is a protocol for networking sound synthesizers, computers, and other multimedia devices for purposes such as musical performance or show control. OSC's advantages include interoperability, accuracy, flexibility and enhanced organization and documentation. The first specification was released in March 2002.

is that an array?

perhaps you should instead look for the presence of a material in array.0

however that works idk lol

And you definitely have the variable set in the inspector as well?

#

get materials 0 is the same as get material (singular)

void ridge
#

It seems like they should be using get material if that's a thing

unborn hornet
#

Preferred, yea. Saves a node

void ridge
#

Well, but also, the get materials node is probably expecting a whole different type of data than what that variable node is outputting

#

I might be thinking of it wrong, though

unborn hornet
#

Not really. The singular version simply returns the 0 index implictly of the plural.

#

Like I said, it saves a node. But that's mostly it.

does it say anything else underneath that? Perhaps something about a 'null reference'?

#

you can find a little more info here: https://docs.vrchat.com/docs/debugging-udon-projects#finding-udon-errors
My first guess with anything that calls a method on the VRCPlayerApi is that your player reference does not point to a valid player. But I'll need more context if that's the case. Like - what are you trying to do, and what does your graph look like?

Anyone know how to set Interaction Text using Udon?

I see the "Interact" event but doesn't appear to have any configurations. Have been poking around the Udon API but nothing is obvious

#

I want to change it from "Use" to something else

dapper lion
#

so heres a quick helper, you can import udonsharp and itll have interaction scripts that you can edit to change the interaction text

unborn hornet

Or (at least until the next mainline release is published) you can do the following

Haha yeah once I import Udon Sharp I'm never going back to graph... so much work to do an "If else then" 🙂

what would be the best way to take multiple peoples names and set them to toggle something locally if they join?

#

I did it for 1 but the others don't work

quaint onyx
#

Quick question, can I somehow redirect the lines so the code looks better? By redirect I mean manually chose their path

cold raft
#

you can write the code in c# with udon sharp to make it look better 😄

quaint onyx
# cold raft you can write the code in c# with udon sharp to make it look better 😄

XD, I planned to learn regular Udon first since that way I get a list of all functions and all the parameters for the function's input and output, which sorta compensates for the lack of documentation. VS does give both but in a way less appealing way. That's more of when you know what you are doing and what functions you have available.

#

p.s. I do prefer classic, text coding, over the graphical one, but I can't deny graphical coding does have it's benefits, along the weaknesses.

void ridge
hallow sable
#

so like rn I have something that enables a game object locally for a person when they join, only for them.

#

It works for the first person but how would I go about doing multiple people?

#

didn't work :/

#

not sure how to do multiple names at once

#

kinda new to this

It's all good you're not the first person to do that (and probably not the last 🙃)

#

Could you delete the image above and post one that's zoomed in/higher res? this is hard to read
whatIsThisAJpegForAnts.gif

hallow sable
#

LOL sorry yeah

#

ill show like a zoomed in part

#

so I started with that

#

each player that joins, it checks the name and then if it's that persons name it unlocks it for them locally

#

but below that

#

I tried it again

#

it only works for the first one

#

there is prob a way easier way

void ridge
#

I think that might be happening here, but I'm not sure this completely matches the behavior I've seen. Just sounds close.

viral hound
hallow sable
#

is there a better way to turn on stuff for certain peoples usernames?

void ridge
hallow sable
#

uhh

void ridge
#

As far as I know, matching the string of a username is the only way to grant certain behaviors to certain people, so yes, as far as I know you're taking the correct basic approach.

#

It's limited because username isn't a perfectly stable identifier, but it's pretty stable, so, good enough 😛

hallow sable
#

yeah I just don't want to use a keypad bc those aren't as secure as this if it's possible

#

is something more stable then?

#

besides a keypad for example

void ridge
#

Well, I'd argue that this is less secure, because in this case someone might just know they can change their username to match an allowed username

#

So depending on how sensitive what you're protecting is (I hope not terribly so if you're uploading it as publicly accessible data 😅), you might consider that

hallow sable
#

but they would need the exact username no?

#

or could it be like one of those oculus names like so and so 4b70a

#

I mean it's not crazy stuff but stuff like for events I would like to keep away from the public if possible, just easier to keep this secret then a keycode

#

unless you had a suggestion D:

#

I have yet to try out Udon. Is it something you can just add to a world?

#

The test world I made is SDK3 based

void ridge
#

Udon is the node-based programming language that's included as part of SDK3. So really your test world already includes it.

#

The VRC_World prefab you probably used has a prefab Udon script attached to it. So congratz, you've used udon 👍

rustic mango
#

I did not use any prefab. I kinda did things the hard way lol

#

figuring out colliders was kinda fun though

dapper lion
#

omg learning colliders was so annoying lol

rustic mango
#

and it being node based... is there any way to edit it in text form? or is it node only?

dapper lion
#

@rustic mango you can use an add on called "udonsharp"

void ridge
#

Yeah, there's a third-party thing--that.

dapper lion
#

ok, has anyone had an issue where when publishing a world, it gets stuck at "preparing file for upload" and doesnt progress?

void ridge
#

It just replaces multiple Branches with multiple Boolean.ConditionalOr nodes

#

Also, it replaces your OnPlayerJoined node with Start, since OnPlayerJoined isn't quite what you need. I'm actually not sure it even fires in the case where a player is the first to load in to a new instance 🤔

#

Another design point to consider with this is: with a code, you can expand the group of people who have privileges by simply sharing the code. With this approach, you need to push an update to your World to add more people.

#

I have my own related question now

#

Is there a "late start" event that fires as the last step of initialization? After everything relevant to VRCPlayerApi has been established, and after the user should have started receiving network data?

hallow sable
#

to be fair I won't be adding too many. just worried about if a code was every spread

#

so event start is just when the world launches? @void ridge

void ridge
#

Start fires locally for each player as they load into the World

hallow sable
#

ah gotcha cool

#

ty so much

void ridge
#

(actually, I think technically it fires when a script attached to an UdonBehavior starts, which is a thing that will happen for an active UdonBehavior that exists at the time a world is loaded, but it will also happen if a script gets re-started I guess?)

hallow sable
#

ah fair enough

#

so it should fire each time locally for a player then?

#

instead of for everyone each time a player joins

void ridge
#

Correct

hallow sable
#

cool ty 🙂

void ridge
#

A warning, though:

#

As I talked about above, sometimes Start fires too early for some important information to be loaded. I don't know whether or not that includes a local player's display name.

hallow sable
#

hmm ok

void ridge
#

If it does fire too early, then Get display name will return "a user is no one" and the Branch will receive False. So I guess watch out for that? If that happens, I'm curious to know

hallow sable
#

gotcha

#

also weird question but would you happen to be familiar with occlusion if I had questions? kinda a big thing I need help with and would really appreciate it

#

if it could be talked about through dm's

void ridge
#

#world-optimization is your channel for those questions, and I'm sure @dapper lion will jump to help you out because they're just bananas for optimization and lighting 😛

unborn hornet
#

Though whitelists are usually small, so it might not be needed, unless you wish to modify a whitelist ingame (for example you want to whitelist a guest DJ).

void ridge
#

Oh, right, yeah. There is the possibility to add an in-world input field where you can define new user name strings. But you'd have to do that for each instance load, so that's only practical for one-off events (like things you'd need a DJ for, yeah)

#

Input field, or a magic wand that lets you just touch the person you want added, and that opens access for them 😄

unborn hornet
#

lmao magic wand.

That desktop newbie jumping around like a dork MITM's the magic wand action

void ridge
#

magic wand touch + trigger pull

unborn hornet
#

Yea, that's what I meant by "action"

#

Like trying to select a user with the menu open in a crowded place lol.

void ridge
#

right, of course. Ideally you'd do it not in a crowd. Depends on your constraints. Design choices 🙂

hallow sable
#

wait so what exactly is conditional or btw? @void ridge

void ridge
#

It's an OR, just, like in any system of logic. If either of the conditions are True, then OR is true, and otherwise false.

#

"Conditional" means something that you don't have to worry about in most circumstances. Just treat it like an OR.

#

But don't treat it like an oar. Then you'll really be up the creek.

hallow sable
#

gotcha

#

would it be better instead of using event start I use event interact with a button that basically checks permissions and enables what I want?

#

@void ridge

#

so it works 100 percent of the time?

void ridge
#

That's an option that would work, yes. Did you try using Start and find that it doesn't? Don't let me scare you away from that, it very well may work just fine.

hallow sable
#

I have not yet but I would find it easier to just use a button that just says "so and so does or does not have perms"

#

one more thing @void ridge

#

if I was setting it up so it would say who had what perms, how could I setup like a text that would say "someones name does or does not have perms"

#

like doing "name" + does not have names but in udon graph

#

like that?

void ridge
#

That one I'm less knowledgeable about. It looks like you're on the right track, you're using a canvas?

use String.Format like "User {0} does not have permissions", and connect the user's name to the Object input. You can do this with up to three objects per String.Format node like "User {0} cannot {1} the specified {2}" and connect objects to the three Object slots (just pick the right method signature from the dropdown)

chilly aspen
#

The string might be overflowing the variable? Try with a single character.

willow tartan
limber jackal
#

they're unicode

#

if you make every character less than 128 does it solve this problem? or is there a setting to make it encode everything as unicode?

willow tartan
#

unicode characters take more space in the serialized message (probably UTF-8 encoding?)

#

there's a space limit to how much data can be serialized per object

#

probably somewhere around 128 bytes, with some unknown amount of overhead

#

you're exceeding that

limber jackal
#

gotchya. that makes sense. Is there some setting in unity I have to change to use ascii? or do you just never let a character's numeric value exceed 128?

willow tartan
#

Unicode is fine if you make the string smaller

#

And yes, char values under 128 should make things more consistent

#

For reference, I've had success with 28 unicode characters

#

Haven't tried more

i know this is super basic, but the udon/coding thing is still sooo new to me. So i know how to make a mirror toggle button, but I want to make it so you can't have both the normal and the optimized mirror on at the same time. So how to i make two buttons which toggle on and off mirror, but that ALSO automatically turns off the other mirror?

willow tartan
#

Add a node to each which disables the other mirror object

edgy moss
#

but what would that node be? I know how to use the unary negation to toggle if something is on or off based on the state it's already in, and I know how to do SetActive. but i don't know how to create a "SetINactive," so to speak

willow tartan
#

SetActive with a value of false

edgy moss
#

oh. lol

#

so just leaving the checkmark unchecked?

#

or rather? checking the check mark? which reverses the bool....?

void ridge
#

Setting to a checked check mark sets it as True

#

If you're inputting a Unary Negation node, then you won't have any check mark at all, since that only exists to let you define a default value nvm I read what you were saying more carefully

#

Yes, setting to an unchecked box sets it to the value of that box, which would be False

#

Checking does not mean "yes, toggle this," it means "set it to true." If the bool is true, it sets it to true. If the bool is false, it sets it to true.

edgy moss
#

awesome, thank you so much for explaining that. i just could have sworn I have used SetActive before and not checked the box, but I suppose not. it makes sense now, thank you 🙂

@willow tartan thanks so much! that fixed it

Is there a way to detect when players leave an area by respawning of changing world or logging off? I need an area to unlock when nobody is in it

tall vault
#

OnPlayerTriggerExit event with a trigger volume that covers the area, and OnPlayerLeft event

cunning mist
#

OnPlayerTriggerExit fires 99% of the time when someone respawns, and I think, uh, leaving the world doesn't trigger it as far as I've seen. OnTriggerExit of any sort doesn't fire when an object is destroyed, which is what happens when the player leaves.
It's not ideal.

If you use the stay event it gets called constantly

It'll keep halving gravity

paper plinth
#

oh right
thanks

native estuary
#

And if you don't check for local player it will do it for everyone when one person enters

paper plinth
#

so it calls every scan?

#

#

awsm

zinc scaffold

Probably better to define 2 variables, set it to the lower one on trigger enter, and to the higher one on trigger exit

paper plinth

#

and also check for local player

#

thanks

#

is there a way to enter a trigger and then leave it without triggering onplayertriggerexit?

native estuary
#

Just don't have a on exit trigger?

#

Or how do you mean 🤔

paper plinth
#

err I'll rephrase that

#

is there a way for a player to enter a trigger zone and then somehow be able to get out of the trigger zone without triggering onplayerexit
like when I scroll up it seems the player can leave the world

#

if so, I guess I'll have to periodically check for the player? If I use a player entering a trigger zone to cause a game mode, then the player exits the world with the game mode active, the game mode will never deactivate

#

when, I think you're right, just don't do that

#

because it seems the player can break the game or someone could get DC'd or whatever and break the game

floral dove
#

@paper plinth - yeah, this is a known issue without a clean solve for now - since the Trigger methods are resolved by Unity's Physics under the hood, OnCollisionExit / OnTriggerExit will not be properly called if a player is teleported, quits or crashes. You could do something with OnTriggerStay, which fires every frame that a user is within a Trigger. You'd probably just want to somehow mitigate it so you're not updating that every frame.

paper plinth
#

cool that's not a hardship, thanks

unborn hornet
#

Checks local player position against an arbitrary collider/trigger. True = player in collider, False = player out of collider.

📎 unknown.png
#

Could add even an additional boolean flag that is set using the OnPlayerTriggerEnter, which begins the checks, depending on the design choices.

#

Like so. The "during" logic would come off the green arrow output, where the "exit" logic would come off the red arrow output.

📎 unknown.png
#

All that's left would be to work on the logic to cancel the game mode when the player leaves (probably via OnPlayerLeft event)

@gilded citrus Are you trying to make general background music for a world?

gilded citrus

no, right now I'm trying to get a video player to be able to be heard all across a room

unborn hornet
gilded citrus
hushed gazelle
#

@gilded citrus That's not really something you'd want for a couple of reasons; It's less realistic, potentially annoying for anyone else in the room not wanting to watch the video, and detracts from the video quality itself because you're just getting audio arbitrarily in your ears rather than relative to the video player's screen position like watching an actual TV. Just add a slider for the audiosource's volume if you're worried about people in the back missing out.

unborn hornet
#

In game, during runtime.

hushed gazelle
#

@unborn hornet Don't worry; I made sure to bring up exposing all three interact variables and not just the text in the Canny.

unborn hornet

Solid 👌

gilded citrus
hushed gazelle
#

And I'm trying to suggest a better alternative.

unborn hornet
#

@gilded citrus On the AudioSource look for the 2d->3d slider.

In the nodes I think it's called spacialization?

That can be adjusted during runtime. My TV has a button that toggles between 3d and 2d.

I would check if it works in game cause the playerapi class is not included in the sdk which will pull a error when you try and use it. Only unity classes will work correctly, vrchats wont unless you are in game.

are "on enable" events supposed to fire on start from now on? or is that a hiccup?

@wanton heron i cant find that box thingy (and no idea how to use it)

not the best solution, but it works

@noble pagoda on the inspector tab there should be an option to add component

it works, and its better than the cube...

floral dove
vagrant coral
#

Cool!

#

ummm one thing tho.. I use "on start" to set variables in some udon behaviours - does that mean they cant use these variables "on enable"?

#

or is there a hacky way to access "on awake"?

floral dove
#

that's right - in Unity's execution order, OnEnable fires before Start, and you cannot guarantee that all your references will be available until Start. If you want to simulate the previous way that it worked, use a bool to detect whether your object has run through Start yet so OnEnable can skip its first execution. There's no Awake event on UdonBehaviours.

noble pagoda
#

@wanton heron you know what i mean ../3d object/cube is not the same thing as a physbox

# scarlet lake Hey guys, I have a question about syncing physics. I'm trying to create a pinbal...

synced physics is floaty as it follows behind the owner of the object and tries to interpolate to stay updated. If you want it to be more accurate, you'll have to roll our own solution instead of using the built-in sync. Like - when a ball is hit by a flipper, update a synced variable with information about how the ball was hit and then apply that to each local version. Or record the position of the ball and move each local flipper to hit it at the same point.

Does the "VRC Unity Video Player (Script)" component currently support multiple Target Audio Sources? It seems to only want to output audio through Element 0 and nothing else.

📎 unknown.png
#

In that screenshot, it'll only output audio through "VideoAudioSource."
If I simply swap their positions so that "Subwoofer" is first, it'll only output audio through "Subwoofer."

#

@scarlet lake I had the same problem, but I couldn't figure it out either

dapper lion
#

ok, so unity player will default to a sort of "fake mono" but for some reason if you were to set it up lik a normal avpro video player, you can get up to the 8 audio source limit (for groups)

cunning mist
#

So from what I've noticed, audiosources for the Unity Video Player work like channels and are basically irrelevant past the first one. I recommend using the AVPro one for anything related to that.

void ridge
#

I wrote a "cleanup" script for some rigidbodies which check every couple minutes to see if they're (1) sleeping and (2) far from where they belong, and if so, GameObject.Set Position moves them back to where they belong. These objects have the "sync position" box checked. I discovered last night that after the conditions are met and the position set executes, they become desynced.

#

It seems like maybe the owner is seeing them as cleaned up, but non-owners don't get the update. So the question is: is position sync not updated for sleeping rigidbodies?

obtuse agate
#

Right. You need to wake it up

void ridge
#

Yeah, that was the plan. I just wanted to confirm that that was the precise reason for the desync

#

Can I be even more slick than that and put it straight back to sleep? Or if I do that too quickly, do I risk doing it between network updates such that the syncing never actually happens? 🤔

obtuse agate
#

I haven’t tried it personally, but according to Unity doc, the rigidbody will sleep automatically after idling for a while

#

So I think there is no need to call Sleep

void ridge
#

For sure. Just as an exercise in not wasting resources, though, it'd be cool to put something right back to sleep if I know it doesn't need to be awake. That's why Rigidbody.Sleep is available after all, right? 🤷‍♀️ I'm sure it only becomes important at large scale with a bunch of rigidbodies or other network loads.

obtuse agate

I guess you need to test it in game😅

follow-up question, sorry to bother

just out of curiosity, what's the design principle behind having both types of video players in a world?
i know that the vrchat documentation basically says that AVPro can support livestreams
and Unity Video is otherwise ordinary

is there an intrinsic benefit to something like USharpVideo (prefab) switching between Unity Video and AVPro on demand?
would I lose a benefit if I went 100% AVPro?

📎 unknown.png
cunning mist
#

I think the U# prefab has that toggle for swapping between syncing systems, rather than swapping between Unity and AVPro. I could be wrong though.
I personally just use AVPro.

scarlet lake
#

oh, i see. thank you very much!

obtuse agate
#

@scarlet lake I’d love to use AVPro only, but it has a few issues:
Doesn’t work on win7.
No audio on certain headsets (bitratesampling rate issue)

floral dove
obtuse agate
floral dove
#

thanks!

obtuse agate
#

This is a major issue for DJ stream. Many people who uses a wireless headphone can't hear the music

#

Unity's builtin VideoPlayer doesn't have the issue (i guess Unity does some resampling), but it can't play stream😄

floral dove
obtuse agate
#

Yeah but we still hope VRC can somehow fix it.
Right now video player prefab creators have to maintain both kinds of video player to work around this issue partially.

#

Music streamer works around this by streaming at a particular audio sampling rate, which is not the default value in OBS.

If I was to set an object to the player's head on the node position, how would i have the object rotate in the z axis according to the player's direction?
Ex. Player is looking front while object is facing front. Player rotates to the left and object rotates to the left. But if lets say the player looks down, i do not want the object to rotate downwards

floral dove
stark adder
#

Or perhaps unity constraints ? @floral dove would that work 🤔

#

rotation constraint 🤔

floral dove
stark adder
#

They should work.. but yea I have not used them much too..

#

@dawn oxide try using the rotation constraint just lock uncheck x-axis and y-axis and only keep z-axis locked and activate it and that should work just fine

dawn oxide
#

i'll try it out now ty

dawn oxide
#

So I'm an idiot and forgot I'm not experienced in udon much yet but I'm getting there

#

this is what i have so far and the 3 nodes on the right i'm not sure if those are the correct ones or not

floral dove
#

sure, this should set the 'PlayerIcon' to the position and rotation of the Player's head. A few tips:

  • Since LocalPlayer is 'null' in the editor, this will throw an error when you hit Play in the editor. No biggie, but just so you know.
  • You can use Transform.SetPositionAndRotation to combine those SetPosition and SetRotation nodes into one.
  • If you're going to use rotation constraints, you won't need those three nodes off to the right
void ridge
#

(also maybe worth noting: Transform.Rotate is almost surely not a good fit for this, since that adds a rotation to the current rotation, rather than directly setting it)

floral dove
#

yes, good point^

dawn oxide
#

alright ty

#

so most likely my object is just fine when in game?

void ridge
dawn oxide
#

oh i do

#

That's how i am able to check if it's not rotating correctly the way i want it to

void ridge
#

Yeah, that should be a good start then. Note that if this is just the object itself, this will plant it right in the middle of your skull 💀 if you want to put it above the player's head then you'll need to make some kind of change, depending on your needs.

#

You can offset it by parenting it to an empty object and transforming the visible/functional part relative to that parent (and also, this graph would need to manage that parent, rather than this object). Or, you can just add a Y value to the position vector3 value.

#

Those will achieve different things, actually, so it depends on what you want.

dawn oxide
#

One thing I still haven't figured out is the constraints as well

void ridge
#

Expand Constraint Settings to get what you probably need. Let me know how it goes 😛

Not completely sure. Might have something to do with the actual audio settings (range/gain/far/whatever).

hi there im having some trouble getting objects to spawn globally. basically im making a custom world for me and my friends to play cards against humanity with our own cards. i already have the system working for spawning cards. tho they only spawn locally. and when i get them to spawn globally every player sees a random card.

unborn hornet
#

Synced instantiation is not supported yet. You'll want to use an object pool method and just sync the content changes.

mossy atlas
#

how would i do that?

unborn hornet
#

You'd have an array of cards already existing in the scene, then you'd have some sync logic to make any updates for custom card text (if I understand what you are trying to accomplish).

#

It's not exactly trivial to do that though.

#

Network sync is challenging.

mossy atlas
#

the text on the cards is done via textures actually

#

all cards are pre made i just need the syncing

#

would it be possible if i gave every table its own array of cards?

unborn hornet
#

Oh, so there is a known finite list ahead of time?

mossy atlas
#

yes there is

unborn hornet
#

That's a bit easier.

mossy atlas
#

153 whites and 63 blacks

unborn hornet
#

So the most straight forward way would be to make a copy of all white card decks for each possible player.

#

And then instead of instantiating it, you would "respawn" the desired cards from that player's deck. (Basically a transform move and a visibility toggle)

#

But all possible cards would have to exist ahead of time.

#

That's the object pool concept.

mossy atlas
unborn hornet
#

Yea.

mossy atlas
#

but the randomizer still moves a random card per player. no one sees the same card

unborn hornet
#

Is the deck always in the same sort order at the start?

mossy atlas
#

yes but the randomizer chooses a card per client instead of global

unborn hornet
#

Ok, i might have been thinking a bit incorrectly about this...

So the problem is that the random index being chosen is not being synchronized between clients?

mossy atlas

yes that is indeed the issue
