I think you misunderstand how the voice distance works. There's no way to "trap" a player's voice in a collider

#

You also probably don't want to change the near voice distance, or players will be extremely loud or not audible at all

kindred pendant
#

ok so how do i keep their volume the same throughout the radious i set

eager olive
#

I would not advise it, but you can connect the player two the second node the same way as you did the first node.

kindred pendant
#

huh? how?

eager olive
eager olive
kindred pendant
#

so theres a player node?

eager olive
#

It might be worthwhile for you to look at some more Udon basics, it seems like you're still unfamiliar with the interface

kindred pendant
#

which is why im trying to figure it out

eager olive
#

The node on the left, OnPlayerEnterTrigger had a player output.

kindred pendant
#

so put it in a triangle then

eager olive
#

Again, you might want to look into some of the basics... Triangles are for execution. They determine what happens in what order.

#

All other nodes carry data.

kindred pendant
#

unfortunately i need to figure it out now, since my world is already public

#

i cant spend 3 hours reading through something that isnt really going to help with this problem

eager olive
#

I believe I've already told you the answer, actually.

#

Your solution already works, if you delete the second node.

kindred pendant
#

so your saying onplayertriggerenter connects to setvoicedistancefar and the player connects to both far and near

eager olive
#

If you want a player's voice to change again after leaving, you will however add more code.

eager olive
#

But yes, that is how you would connect it.

kindred pendant
#

currently, when im in the bubble everyone is just really quiet and it cuts off further then what i want it to

#

so basically i need it to cut off in shorter distance but be louder

#

ive sort of got it too work. but everyone is just too quiet

eager olive
#

Sorry, I'm having trouble understanding your problem.

kindred pendant
#

ok. ill explain what im trying to do

eager olive
#

By everyone, do you mean everyone in your world? It shouldn't affect people unless they enter the collider.

#

If time is really critical for you, I have a finished U# script you can use.

kindred pendant
#

i have 6 booths in my world. intended for private talking. in the booth you shouldnt be able to hear out of the booth. nor in the booth when your out of it.

eager olive
kindred pendant
#

so im trying to make it so your voice only travels so far. but is louder at the start

eager olive
#

The best approach would be to teleport players, actually. because otherwise you would have to change the volume of every player in the world

#

Treating the booths like private rooms would make things much simpler

kindred pendant
#

so theres no way to make it so once you enter the trigger your voice only travels to a radius of 4 meters and no more?

eager olive
#

Maybe someone else can help you if you want to go through with your initial approach, but I don't think it's feasible if you have very little time

eager olive
#

But you mentioned that players also shouldn't be able to hear what's going on outside the booth.

kindred pendant
#

ok so hopefully it should be fine then if i test it now

#

well the voice wont travel that far for them to hear

eager olive
#

Also, you'll also need to add something that makes players louder once they leave the booth

kindred pendant
#

if i stand 6 meters away from the booth. i shouldnt be able to hear them if the far radius is only 4]

#

what about if i added voice gain?

eager olive
#

It sounds like you won't be able to fix this in such a short time span. I'd advise taking a closer look at the documentation, learning some more basics, and maybe switching to a teleport approach instead of changing voice range

kindred pendant
#

how would i also connect voice gain to my graph?

eager olive
#

Same way as I previously explained. You would daisy-chain the execution nodes and add the player input.

kindred pendant
#

what im doing now is sort of working

#

i just now need them to be louder

#

ahh

eager olive
#

Again, Udon basics might be worth looking into 😖
SDK has a lot of examples, too

kindred pendant
#

ill be looking through the documents eventually. doesnt rn tell me what i need to know tho

#

which is why im asking for help

eager olive
#

Well, hope I could point you in the right direction!

It sounds like you have a slight misunderstanding on how The Sphere works. Yes all players are put into stations, but the station isn't for the local player, but for all remote players. Everything about The Sphere is actually fake. The player is always upright and moving around actually moves the world. See the attached video of what it looks like in editor. It's basically a giant hamsterball. The reason for the station is so that locally you are mobile, but remotely, the players are stationary. This allows you to move the station itself around to move the player sitting in it. If you sync where the local player is relative to the sphere rotation, then you can apply that rotation to on remote clients, making it look like you are on the edge of the sphere.

Just so you know, The Sphere was built in SDK2. Udon stations might be a little different with mobile vs stationary.

What's a fast way to covnvert SDK2 to SDK3, using the CyanTrigger method.
Or any tutorials.
I'm having a hard time trying to fix and convert my SDK2 to SDK3 without the need to redo all the triggers all over again.
I've already deleted the SDK2 on my old project and imported SDK3

karmic gust
#

Anyone know how to fix this issue?

unknown.png
#

No reimporting the SDK does not work
No restarting unity doesn't work

grand temple
#

might be the wrong version of something. Do you have unity 2019.4.31f1 and the latest VRCSDK?

karmic gust
#

Yup

#

both are latest versions

grand temple
#

no, unity 2019.4.31 is not the latest version. Make sure you have that specifically

karmic gust
#

latest as in the lastest one VRC wants.

grand temple
#

ok. Is this a project migrated from something else, like 2018 or SDK2?

karmic gust
#

It's migrated from 2019.4.30f1

#

there was no SDKs before hand

grand temple
#

that's minor enough that it shouldn't matter

karmic gust
#

This seems to be a Unity problem, only issue is that google searching hasn't been the best helper of this issue

grand temple
#

not sure exactly what it is, but first thing I would try is a clean install of the SDK. Close unity, navigate to the project and delete VRCSDK/Udon folders, reopen unity, reimport VRCSDK

karmic gust
grand temple
#

did you fully delete the folder while unity is closed? If you just import on top or delete it without closing, it's not the same

karmic gust
#

Yes, i've deleted the folder while unity is closed

cunning mist
#

Maybe go to an empty scene before doing that though just as a precaution

grand temple
#

nah that's not necessary

karmic gust
#

Its not a SDK problem

#

its a Unity Engine problem

#

but nothing on google is helping

cunning mist
#

I wouldn't say so, it definitely sounds like something is causing the VRCSDK specifically to fail to compile. Which version of the SDK have you imported?

grand temple
#

it's a VRC script causing the issue because it doesn't see something in unityengine

karmic gust
#

It can't load the sdk because its missing UnityEngine.UI or a dependency of it

#

its the latest version of the SDK

cunning mist
#

If UnityEngine.UI is failing, try creating UI Button in your scene and see what happens.

grand temple
#

I guess you could go to window > package manager and search UI, see if anything about this page is weird?

unknown.png
cunning mist
#

I've run into that once before but it definitely broke my project waaayyyy more than just two VRC errors

karmic gust
#

Button appears fine

cunning mist
#

What's the new error there at the bottom?

karmic gust
#

the latest error is complaining about scaling

#

the third is about cloth or something

grand temple
#

maybe there's some other package in this project that's causing a problem

karmic gust
#

Hmm

#

Lemme delete some scripts from their folders

#

from other packages

#

they can't be used anyway

cunning mist
#

One thing that may be able to resolve this is clearing some temporary/cached files and forcing Unity to reimport a large portion of your project. This can be done by deleting your Library folder which is alongside your Assets folder while Unity is closed. This may take some time to open your project after doing but this has definitely saved a few projects of mine.

karmic gust
#

thats where the file is, that unity is complaining about

unknown.png
#

so it could work

cunning mist
#

It will regenerate most of these files again when you open the project again, just be prepared to wait a few minutes depending on how big your Unity project is.

karmic gust
#

Its a bit big

#

but its on an SSD so it should be fine

we'll see

I've tried to make a zone where peoples audio are amplified when they enter it. But i'm not sure how to make a "late player sync" for this system. It kind of breaks whenever someone join while people are inside the box collider trigger. Any thoughts?

#

OHHH. Okay okay, thank you thank you both. I'll give it a try.

wind atlas
#

You could honestly just use OnPlayerTriggerEnter without the SetOwner, because it should be called on each client anyway.

grave lantern
#

ah right. I'll give it a go

#

That mic btw is a life saver 😛

wind atlas
#

The case becomes a bit simpler then. After that, you have to handle late joiners. Ideally, OnPlayerTriggerEnter will get triggered as soon as the late joiner comes in, because you know, the players get teleported to your zone. But idk if that's the case.

#

Alternatively, you would need to track the players yourself and then sync them using a manual variable.

you should probably have the same bool for both cases

You probably want to just have one Bool for Open that opens the door when true and closes the door when false

Ignore how old this reference looks but you can get the current value of that bool from the animator and flip it's value.

Hello! I'm very new to Udon and I was wondering if there were tutorials for or if anyone knows how to do these two things.

  1. Toggles that toggle other items off. I know how to do a singular on/off toggle and an array, but I don't know what to add to the graph to check if other items are on and turn them off.
  2. A toggle that cycles through a material change. I'm guessing this will entail animations along with Udon. I'm wondering if it's at all similar to doing it on an avatar?

Wondering if anyone can help,
Ive been trying to set up a mic boost for the world im working on to basically have the DJ play through his mic and by greatly increasing the near/far values i can have his music fill the room without it being directional, basically making him 'global', however because of it having no audio falloff, its super loud.
I usually fixed this by adding into the graph a -20db voice gain but no matter how much i adjust the -gain it doesnt seem to shift below 0, i cant get it any quieter.
I have tried guribo better player audio (increasing far & voice volumetric radius) and can get distance but i still cant set the gain to a negative value.

Any idea's or workarounds, i just want everyone in the room to hear him at equal volume. Ive attached my graph.

do lists exist in udon?

grand temple
#

no

scarlet lake
#

damn it

#

does anyone know how to make a sequence on Udon? if lists aren't a thing here, then what is?

#

things are so much easier on python or C# ;;;

dawn forge
#

I love Lists, but what are you trying to achieve @scarlet lake ?

scarlet lake
#

I'm trying to achieve something like that wile using the least resources possible

dawn forge
#

I do not, but I read up while quick, you're wanting to play random notes?

scarlet lake
#

so there would be a few buttons that can be pressed at random, but when a specific combination is pressed, it recognizes it as a specific song and has different effects

#

I wanted to recreate that in my world, but making it easy to make it recognize many combinations, while still making it not very RAM heavy

#

gotta have it quest compatible, after all

dawn forge
#

Instead of arrays you could always concat to a string with mnemonics?

scarlet lake
#

I'm not sure I follow

fiery yoke
#

However usually you dont really need the dynamic allocation aspect of a list, since just having a decently sized array is fine.

scarlet lake
#

hold on, I thought we couldn't use non-udon scripts in our worlds

fiery yoke
#

Ohh....UdonSharp is a C# to UASM compiler written by Merlin (a VRChat user). It converts C# code into Udon Assembly relatively well.

scarlet lake
#

ah, wonderful

grand temple
#

it doesn't sound like what you're trying to do actually requires a list. Just use a static array, you don't even need to deal with dynamically resizing it

fiery yoke
#

Yeah thats what I was saying. Lists are really just a "convenience" thing.

scarlet lake
grand temple
#

wtf python just straight up doesn't have arrays? damn

#

oh there are libraries for it

scarlet lake

fiery yoke
#

Udon is three things: Udon Assembly, the Udon VM and the Udon Node Graph

scarlet lake
#

udon vm?

fiery yoke
#

Virtual Machine. The Udon VM runs the assembly instructions, which are generated by the Udon Node Graph.

grand temple
#

The real power of udon is that it's a virtual machine that runs assembly. The node graph is just one way to compile nodes into assembly. U# compiles C# into assembly and CyanTriggers provides an inspector based interface for generating assembly

scarlet lake
grand temple
#

not sure if it will even work in the latest unity with latest VRCSDK

scarlet lake
grand temple
#

if it doesn't, and you're really desperate for python, you could try an old SDK. But you'll probably have a better time with U# if you're willing to learn C#

scarlet lake
fiery yoke
#

The thing is that the Udon VM is not really a VM in the original sense, as it does not virtually process the instructions on its own architecture.
The Udon VM is essentially just a "Housekeeper". The VM hooks into the underlying C# code and calls the actual methods there.

In short: Udon is a wrapper around C# allowing access-control and abstraction.

#

Hence why it makes the most sense to actually go from C# to Udon, as its the closest relationship.

scarlet lake
#

ah, I see

#

so it's like a skin

#

C# is the gun, the variables and attributes are the ammo, UdonVM is the skin (I don't know how well this FPS analogy will hold up)

grand temple
#

the VM is just a C# script so it's going to be a subset of C# in one way or another

scarlet lake
#

I meant C# as the programming language, not as the script

grand temple
#

yeah

scarlet lake
#

anyway, yes, the python list is pretty much the c# array

#

thanks, guys

grand temple
#

kinda. Only difference is that you can't just add new entries. You have to specify the length of the array when you create it

scarlet lake
#

that's only better for organization

#

if it doesn't compile, I forgot something important

wind atlas
scarlet lake
#

I know this is dumb of me, but why doesn't Udon use static variables?

#

I don't want to have to make different scripts if I can combine everything in only one

unknown.png
scarlet lake
#

like, that data is probably crunched by the computer before it reaches VRChat

wind atlas
scarlet lake
#

I do, because these variables need to be shared through different game objects with the same script

wind atlas
#

I see, that's not really possible the way you want to do it as you've noticed.

scarlet lake
#

yeah...

wind atlas
#

There is a U# beta I haven't checked out yet that has a lot more features for OOP stuff.

#

But currently, you have to rethink your approach.

scarlet lake
#

I see

#

thanks

wind atlas
# scarlet lake thanks

Honestly, I'm not even sure that approach is that great in regular C# either. Maybe it's a valid way, but seems a bit wild to me.

#

In general, you already have something like singletons because you have gameobjects. So you already have concrete "things" to store data on and retreive from.

scarlet lake
#

I see

#

so should I make an empty object that does all the calculations (and therefore takes the data from each of the other scripts)?

wind atlas
scarlet lake
#

exactly

#

like the ocarina in Zelda, but with more inputs and more songs

wind atlas
#

That's an interesting problem. I'd suggest to just use an array to store the input. They obviously work different from python :P

scarlet lake
#

yeah, of course

#

I don't want to store in an array, though

#

like, I want every note combination to be possible to play in any key, so that means that I'll be comparing the difference between the last two inputs to a value in an array

#

hence why I was calculating height instead of just getting the notes

wind atlas
#

How are you going to store it if not in an array?

#

Are you basing the ocarina on a specific zelda game in the series? I want to check out how it works there. (haven't played most big zelda games.. sorry)

scarlet lake
#

the correct height combination is in an array, but the input would be two different variables

scarlet lake
#

the n64 controller was very limited, so only 5 notes could be played; since I'm making a piano for this, I want it to be possible to play that same combination in any key (so it doesn't matter if you start in an A or an E; if the melody sounds the same, it should recognize it)

wind atlas
#

Ahh, so that's what you mean by height, to keep the input more flexible.

scarlet lake
#

exactly

#

I think this is a better explanation of what I think the program should be able to do

unknown.png
wind atlas
#

Yeah I see now. So what I meant earlier is basically, on press you call your actual Ocarina script from those keys and send them what was pressed.

scarlet lake
#

I see

wind atlas
#

Thanks for sharing more information, this is an interesting problem. Probably not super complicated, but there are different ways to solve it.

scarlet lake
#

so on press, send the keyIndex value to the main script, update lastKey to be equal to keyIndex, and do the maths from then

scarlet lake
#

thank you for helping me through this

wind atlas
scarlet lake
#

yeah, but I needed someone to help me; U# doesn't have the same capabilities of C#, and I'm more used to thinking in Python, so it was important that someone more experienced in U# told me what was and wasn't possible

#

so thank you for that^^

Is it possible to have too big of a Udon Graph that things start to break?
Like mine just started to chug when I try to connect nodes, but in early testing I didn't have issues, so I released the event I made and now it seems like only one person can complete the event, but it breaks for others at different parts...

Here's a pic of the graph that runs it all, should I just test splitting it to smaller graphs and see if that resolves it, or any other ideas? The event is local, so everyone's doing their own progress at the same time...

#

The thing about Udon is that custom data structures dont really exist. You cannot simply just create an object that holds on to some values and pass it around.
it makes working with Udon really difficult. For example Lists do not exist in UdonSharp, and you cant really implement a List yourself, because Udon does not let you dynamically allocate memory (on the heap). It is allocated statically based on the variables in your Program.

scarlet lake
#

that... sucks honestly

#

but thanks

fiery yoke
#

Well theroetically you can use object[] to hold onto arbitrary data, but that gets really complex really fast, and static type checking goes out the window at that point.

#

You could even implement your own heap with that, but that is far beyond reasonable without some serious dedication and a custom compiler like UdonSharp, that makes using it less abstract.

grand temple
#

you can create your own player controller, but the vrchat player controller is still protected so no

dapper lion
#

ok: so no way to even hide and then move the cursor?

#

acc nvm, thats a weird question, ill try to do some math to follow the cursor then

#

now i have another query: when i put someone in a chair with mobility, and i now in control of a seperate animation override control set up? and if so, can i make it so desktop users can use a left hand via animation controller lol

#

I feel like yes. but also... no since this is probably the 5th most weirdest thing ive done to this game

grand temple
#

You can use stations to give them a custom animator which does whatever you want. But it's also still protected so udon can't touch that animator while it's controlling the player

#

if you only need to read mouse movement, you can do that with InputLookHorizontal and InputLookVertical

plush stump
#

which event should I use for grab a handle?

#

I mean pull trigger for x second

#

If I need the player to hold a handle for x second, should I just use Interact event and get delta time or shoud I use input Grab?

I made a toggle button for switching a object on or off but when I pressed it but the problem is only I see this so its local, is there a way to make it public so everyone see it when I press the button?

plush stump
#

you can use sendcustomnetwork event or Requestserilization/Ondeserilization to do that

shrewd kernel
#

ok

#

I want to make a timer that only decrease when player hold it

#

which node can I use?

cold raft
#

i think there was an event like OnPickupHold or something that triggers every frame its still held

#

else you could use OnUpdate and check Pickup.IsHeld to see if still beeing held

plush stump
#

What if I want the timer to be fixed on the wall instead of being picked up?

cold raft
#

the timer can be on a completely different object, on pickup object you just put an udon behavior with a public variable where you pass in the the udon behaviour that controlls the timer, then you send events to it

plush stump
#

yes but I want my player to hold a switch for 5 seconds to open a door(for example), I don't want them to pick up the switch and walk away

plush stump
#

OK I see OnpickUseUp shall work for this

plush stump
#

null it didn't work for me

plush stump
#

anyway to make a pickup object not move by player?

broken bear
#

Not move like transforms ? Add a parent constraint with all axis constrained to an empty gameobject

#

Not sure if unchecking everything in the rigid body there with freeze position/rotation accomplishes the same thing

What do you mean by prop colliders and station teleporting?

#

If you click on a station and your avatar zooms too far to get to it, it counts that as speeding

prime fossil
#

Flight via colliders

fading cipher
#

Flight via colliders, yep.

prime fossil
#

And teleporting via a modified/moved station exit point

marsh beacon
fading cipher
#

I stopped using VRChat's built-in IsGrounded check and instead wrote a simple raycast... I'm not sure if it scales with the player, I think it's just a 50cm raycast

prime fossil
#

What about armature movement via animclips and enter/exit posestate

#

Aka fake playspace and also real one? (both dont move the player bubble, but the armature)

fading cipher
#

Both forms of playspace it currently allows, because there's no easy way to make a player stop doing that when it's happening

#

Sure you could force swap their avatar, but I don't think that's a good move for that

prime fossil
#

You can put them in a station

#

That pretty much ends it or at least should

fading cipher
#

We do have quite a bit of forced avatar swapping already setup, especially if the avatar is too small or large and/or is missing too many essential bones

prime fossil
#

Id love to try the system in the world sometime c:

fading cipher
#

Sure thing, what's your in game username?

dapper lion
#

you can change avatar heights with stations

#

in the animation override. you can shrink/grow people

fading cipher
prime fossil
fading cipher
#

or vice versa

dapper lion
#

and apparrently you can be in 8 stations at once

prime fossil
#

You can enforce an animation via the station

#

You can kill fake psm with that in theory (set their root transform to y again). Also need to exit pose space tho

dapper lion

ngl. i was preparing to make a station based controller system with like 70-100 instantiated stations per onjoin event

from what i can tell. at least how i did it which is awkward to explain

cus if you do different param layers on a station. you can disable and keep them in the station. and then go to a new station

I got a question, So when I set up a button trigger than makes a box with a trigger that teleports people within that box, It causes the whole map of people to be teleported to that said location, when it should only be for those that are standing in the box. What would be the cause of the problem?

Oh it is a bool, sorry wrong one, drag it from the event (OnPLayerTriggerEnter) Sorry

last geyser
night viper
#

no, because you want the event to fire only when the local player enters the trigger. When other players enters the collider it will check if it is the local player (branch) if it is true, it will fire the next event. If it is false, nothing happens locally (you dont get teleported)

changing the color to magenta keeps the room blue even though i have real time global illumination on

you need to call RenderExtensions.updateGIMaterials() to update real time gi from material changes

I don't suppose there's any simpler ones where you can just drop the item by your hip or whatever, and it sticks? with how that one uses triggers and whatnot, i feel like it'd work poorly with items that can be 'use'-d

whats the easiest way to slowdown fixedupdate so it sends 1 event per second rather than every frame?

Would SendCustomEventDelayedSeconds work for you?

tried that but after 1 second. it goes back to everyframe. but delayed by a second

i need a event every second once

or at least control over that time

my current plan is to use time.Time or something that counts time but I don’t know if thats efficient

I have been having a problem with both SDKs(SDK2 and Udon) recently where when i try to test build a world it just shows this message and stops loading the world, I have tried loading in a brand new project with Udon and only putting in a VRCWorld prefab and a cube for floor and the same thing happens.

I want to learn more optimization so I ask this
With a Udon world, where would I start to learn how to load sections of the world for the player as long as they are in it, like you have spawn and the next room, room 2 is not loaded when player is in spawn, but as soon as the player leaves spawn, Spawn deloads and room 2 loads in

dawn forge
#

@sage whale That's where you can utilize the VRC Object pool to manipulate the objects and their active states.
VRC Object Pool

VRC Object Pool provides a lightweight method of managing an array of game objects. The pool will manage and synchronize the active state of each object it holds.

To make an object active, the Owner of the pool triggers the TryToSpawn node, which will return the object that was made active, or a null object if none are available. Objects may be returned to the pool by the pool's owner, and automatically disabled, via the Return node.

Late joiners will have the objects automatically made active or inactive where appropriate.

Source: https://docs.vrchat.com/docs/network-components

For determining if they're in a room, you can utilize a box collider and provided methods "OnPlayerTriggerEnter" and "OnplayerTriggerExit".

#

how do i sync an int parameter on an animator for late joiners?

night viper
grave lantern
#

Oh it works fine, but it syncs wrongly on late joiners

night viper
#

is it by 1?

grave lantern
#

yea the sync is offset by 1

night viper
#

Is because you are setting the sync value after you set the animator int. So when you click the button, it will get its current int (0) and add 1 making it 1. Then you call the Set Network Scale, which takes the current int (1) and adds 1, making it 2. That value is synced, so late joiners will always get one off. I hope it makes sense.

Anybody here ever had Build & Test not actually make a new build?

Is there a way to turn off the ability to pick up objects in a world? I don't want to turn off the object itself, just the ability to pick it up. I set this up with the target as the VRCPickup script itself, but that results in an error. I'm guessing I need to target the part of the script that says "pickup" and not the whole script itself, but I do not know how to do that.

unknown.png
#

Also I realize turning off the colliders of pick-ups will achieve the same effect, but not all the objects in the scene are kinematic which causes them to fall through the floor when I switch the colliders off.

#

there is no such thing as targeting the array. That's the point of the for loop and the array get, that allows you to set properties on everything in the array individually

But I do have to target something, right?

yes, the pickup that you get from VRCPickup[] get

Ohh I replace "Set enabled" with "Set pickupable"! It was that easy. Thank you both so much. The more I work with this the more I understand the language.

Is the “compiled“ UDON Assembly plain text? And is it going to be interpreted at runtime?

fiery yoke
limber wharf
#

Wouldnt it be better to convert the graph in C# code wich is being compiled to a library

#

I made a test where i made a c# script that rotated a cube and a udon script that did the same. Its such a simple thing but the c# version was 7 times faster. I mean for rotating cubes it realy does not mater but if you want to perform more havy things, it will get slow pretty fast.

I put udon program on a Quad and now it seems to have infinite interaction distance, is that how Interact works for Quad object?

dapper lion
#

check your udon behaviour. it might be set to max trigger distence

plush stump
#

is set to 2

dapper lion
#

might be the collider size

plush stump
#

I can interact with this one from another side of the map

dapper lion
#

whats the size of the transform

#

also your z scale on your box collider might also be an issue but i dought

plush stump
#

I see, if the interactive collider box is behind another collider box, then the interact distance become infinite.

pretty sure people can open the graph .asset in udon sdk projects

I guess I could cut and paste it into paint

it works

it's a display terminal

i would send screenshots if this is for here

does pretty much that

I'll try pasting it into paint

dapper lion

wait. so if it works. whatre you trying to do again?

paper plinth
#

just cause it works doesn't mean it's the best/right way

dapper lion
#

o ic

#

i cant see graph currently so i think SS are best

paper plinth
#

for example, this is how I made it cycle back around to the first (or last) item in the array when it gets to the end (or beginning)

#

intObjectInViewer is what tells you which item in the array of gameobjects to make active

#

that makes them active depending on which number is up

dapper lion
#

i believe theres a subtraction node you can use instead of addition

paper plinth

u mean instead of add -1?

#

lol yeah good catch I got lazy

dapper lion
#

fair lol

#

as far as graphs go. this looks pretty good

#

I don’t know how youre starting tho

paper plinth

this makes the number change when you're not pushing the buttons, like a standby mode that activates after 30s inactivity

paper plinth
dapper lion
#

wait. standbymode is part of the same graph right?

paper plinth
#

yup this is all one graph

#

just the arrows have their own graphs bc idk how to do that without sending a custom event

#

this is on the buttons

unknown.png
#

it is ok to make two nodes go into one like that?

#

this is what the buttons do, they reset the timer and manually change the object to set active up and down

paper plinth

just remember to remove it in game or it might double fire

another thing you could do but dont have to is make a public text and set the text as the int youre using to show which option you are on in number form

ok now i have a question. whats the best way to get relative.velocity and save its value repetitively?

#

or actually. what the best way to get velocity without needing a rigid body?

wind atlas
dapper lion
#

ok so now im wanting to get angular velocity lol. ok so what im doing is making every instrument i can in vr this month. so right now im finishing the marimba and what i want to do is use the velocity of the “mallet” or “mallet head” and set the volume of the audioclip (via playoneshot) to the velocity the mallet was swung

#

and i think..... i should do angular velocity from the hand/pivot point

#

since that is a pickup AND has a rigid body to call from

#

hopefully that makes sence. if you want an example. look up videos of people playing the marimba

wind atlas
#

Sounds similar to swinging a sword in VR, right? I don't think you can use the velocity of the hand, it has to be at the tip.

wind atlas
dapper lion
#

but my reasoning to use angular velocity is because its coming from the rigid body that should in theory be more accurate

wind atlas
#

I can't comment on the angular velocity, never tried it like that.

dapper lion
#

ok. now i have another issue lol: so over the year, i have learned that using 100s of audiosources is not smart. so all my instruments use their own single audio source. howrver, this does make everything feel better. but it now makes it hard to make notes sustain in chords. for example: i want to play 2 notes via playoneshot on getkeydown. and on getkeyup, i want it to mute the previous audioclip, and i have been able to do this with a piano sustain pedal system. but not a note by note system. everytime i release any key. all notes are stopped instead of the key i released

#

basically. i want to control the length of an audioclip in realtime using 1 audio source and roughly 88 clips if not more

#

im doing “audiosource. Stop()” which is most likely the issue. but I don’t know of any other ways

#

i was attempting to do “audiosource.clip = newclip; audiosource.Play();” instead of playoneshot

I don't know when you would use it in regular Unity, but Materials aren't really components anyway. So try getting them via the mesh, that's how I usually do it.

west mural

the type in front is the return type

me think

wind atlas
west mural

yeah true, materials not compoents

humble silo

bruh this.GetComponent<MeshRenderer>().material.color = Color.red; i was doing this

but idk why it didn t work i remade the .cs file

and now it workt somehow

west mural
#

ah, yeah ((MeshRenderer)this.GetComponent(typeof(MeshRenderer))).material.color ...

wind atlas
#

That's why it work in regular unity.

west mural
#

actually, ive been saying bullshit.
Yeah, GetCompoenent<T>() should work in U#

#

only exception is getting an UdonBehaviour

wind atlas
#

And I think some VRC scripts too?

west mural
#

other udonsharp scripts

#

because the u# compiler does some stuff to make that work

wind atlas
# west mural other udonsharp scripts

I meant like stations for example, you also have to cast them... Btw, you are the person with the gravity stations from back then. I am trying to do something similar, but to rotate players so you can walk on planets and stuff.

west mural
#

someone showed off a concept for this a few weeks back at the community meetup

#

only thing is the animation controller

#

you apperently cant set parameters in the station animator

#

so i dont think there is a way to get a working walking animation

wind atlas
#

Oh, I think I saw that in another experiment I did. The animator you put in counts as another class (RuntimeAnimator or something like that), and isn't directly usable...

#

But I'm hoping that you could just use the default avatar parameters to make locomotion work.

west mural
#

you cant set any parameters on the player controller

#

soooooo

wind atlas
#

What I mean is, the parameters that vrc sets for us, like this stuff:

unknown.png
#

But haven't tested it yet.

west mural
#

hmmm, i wonder if velocity is set in stations

#

and if it is set on the station controller

#

but that might work

wind atlas
#

Hopefully, otherwise you need to put people into a wheelchair or something before they can't access gravity lol

wind atlas
#

There is something weird that happens. Basically, on seated desktop, you can move 90 degrees to the left and right before it stops.

west mural
#

doesnt seem like parameters get set in stations

wind atlas
#

Currently, I just made it so I only move the seat when it reaches that amount. Otherwise it uses regular head movement.

west mural
wind atlas
#

Eh, hope that makes sense.

grand temple
#

Wait what, no, udon is NOT compatible with standard assets

#

What you're missing is udonsharp

#

I mean, standard assets would probably cause new errors that suppress the original errors maybe

#

It certainly wouldn't make the pool table work

#

Try deleting standard assets

i want to have a key pickupable object (like a literal key) and once it collides with a door object, the door opens. also kinda want to have that same feature with a cd object and once it collides with a cd player, will play a song. i know it is a common gimmick in some worlds but i can't find any tutorials online on how to do it using udon.

it's pretty simple, you just need to chain together a small handful of nodes. You first need an event which will start logic when something happens. In this case you'd be looking for OnTriggerEnter. OnTriggerEnter will give you a collider, and you can check anything you want about that collider to make sure it's the key that you want. You could check it's layer, check if it's name is exactly something, or check if it's name contains something. All of this would plug into a "branch" node which allows you to only do something if all the conditions are met. On the true side of the branch, you would send a custom event or set something on your animator which tells the door to open

#

There are two main things to be aware of though: First is that not everything you get in OnTriggerEnter is going to be valid. This means it's either null or protected, and as a result trying to interrogate such objects will crash your udonbehaviour. So the first thing you need to do in OnTriggerEnter is to use the isvalid node. If they're not valid, you can just stop there

#

The second thing to be aware of is networking. Technically, all of this code happens on everybody's computer independently. So if the key is synced and a player puts the key into the trigger, then everybody will see the OnTriggerEnter happen and everybody will see the door open. But that doesn't account for late joiners, as everybody needs to see the key actually enter the trigger. What you should instead do is that when you get OnTriggerEnter, you check who the owner of the key is. Then you can do a branch so that it will only continue if the owner of that object is local. Then you can make it so that player takes ownership of the door and sets all the synced variables necessary to sync with everybody more reliably, including late joiners

#

How do you set custom destinations for a VRC_Portal? The world parameter just has "None" "Hub" and "Home" and I presume room ID just targets specific instances?

lavish basin
#

i think its

#

set(vrcportal=none/hub/home)

#

but i might be wrong

craggy harbor
#

vrcCatThink Does anyone experience VRCplayerapi.teleportTo function only teleport player's camera to the destination but leave player's avatar and collider at where it was bug.?

#

Seems the player will stuck on any collider on the way. I thought teleport was immediate position change, does it need a clear path??

#

TeleportTo is highly inter-frame timing dependent. You should never call it from OnDeserialization for example. It's safe to call it in Update. So you might just want to defer it to the next update call.

what is the audio count/voice count limit in game?

Does anyone know why when I double click a script and when I try to write for eg "VRCPlayerApi." it doesn't show the members of the class?

anyone got any ideas on creating the u# scripts? its not popping up

hallow sable
#

how can I on interact get the person who interacted with it's name?

#

I thought I did it right but it's local

fiery yoke
hallow sable
#

so if I was trying to like

#

check who clicked a button how can I do that?

#

like trying to have little pieces and when people click on it, it puts their name above them

fiery yoke
#

There is multiple ways, but if you also want it to work for late joiners, you will have use a synced variable with the playerID or the displayName depending on your needs.

hallow sable
#

I have not been able to find a way so far :/

#

I would be fine with the non late joiner method

broken bear
#

What common events are triggered by other player interaction or movement? Just OnPlayerTriggerEnter/Stay/Exit, what else?

#

I know we run all programming local and our client sees a player cross bounds of a collider, I guess that’s it

dapper lion
#

playercollision, playerjoin/exit, stations. thats all i can think on the top of my head

hallow sable
#

would set owner and get owner be useful instead?

dapper lion
#

theres a few more tho

#

but i mean. if you wanted to post the playername on the text. im pretty sure you would just send a event with the string you have already aquired locally and sending it out globally

#

but i could be wrong. i have not touch playerapi in 10 days

I was wondering if anyone here would happen to know how the recent "Poly Island" world allows players to climb other players.
I'm not an Udon dev, so I guess the question is more whether it's a prefab that's available/sold anywhere, or whether it's currently unique to that author/world?

#

so anyone who knows how i can make a udon graph that triggers an animation when its geting hit 3 times? not sooner or later and its synced for everyone?

vernal magnet
#

Hello, I made this Udon graph to turn kinematics on when colliders turn off. It works, however because kinematics are off first, they don't turn on until I turn the toggle off then turn it back on. This makes the colliders/kinematics turn on and off at the same time. This is the opposite of what I want to happen: kinematics should turn on when the toggle (and colliders) is off, and turn off when the toggle (and colliders) is on. I'm unsure how I should change the graph to make this happen.

What's your question?
You need to put VRCCam where you want your view

will this send a custom event containing the name of the gameobject it's attached to?

Not really a dev question, but what is the general consensus on re-posting worlds that never left labs? I've got an older world I'm planning on giving a facelift, not sure if I should just update the OG world, or repost it as new.

alright, thanks!

#

for object pool, when a player leaves the instance, is there something under the hood that triggers OnOwnershipTransferred, or do I need to plan for a player leave event to return the object

grand temple
#

Either one. onownershiptransferred will go to the master

#

Though many things can trigger ownership transfer so you may get false positives. Onplayerleft is more specific

broken bear
#

I have a trigger area on the objectpoolmanager, I want to assign an object on enter (works), when a player leaves the trigger area or logs out, i want to return the object. Trying to figure out the trigger exit, whether it should be on a rigidbody on the object, or somehow access the assigned object from the objectpoolmanager to return it there

#

I guess I can assign the object onjoin and manage the trigger area seperately on the object through rigidbody but not sure how to get the exit either way

#

hmm I just may scrape it, raycasting this isn't consistent on update for me

#

Long story: I'm trying to object pool a raycast that plants a line renderer on the ground, but only activate when entering a trigger area, and returning it to thepool when leaving the area. I can get it to assign when entering the lake area here, but not sure how to return it when leaving. Also, the raycast sometimes stutters and I get a vertical line as shown in the clip https://gyazo.com/56b41050438678c294e6d49985d7f24c

#

It would be much easier to just assign an object to each player when they join the world and then enable the line renderer when they enter the trigger

#

also the built in object pool isn't really meant for assigning to players. I have a prefab for assigning objects to players on the prefab database, "simple object pool" that would be appropriate for that

broken bear
#

I was actually building off the obsticle course object pool with a rigidbody since I prefer working with graphs, and familiar with that from the jam

grand temple
#

That one can also be used, yes

#

Just assign on player join/leave instead of trigger enter

broken bear
#

I'll move to that, I'll keep at it 🙂

feral merlin
#

Anyone know how to grab a player's name and check it?

#

I want to ban some individuals from my world and need a way to make a check on the player's name

broken bear
#

vrchat discourages hard-coded banlists unfortunately

feral merlin
#

Ah I see

broken bear
#

I think I got it! Set pooled object on join, return on leave, object has capsule collider set on a layer interacting only with a same-layer trigger area, child is a raycast trail renderer. Collision with trigger area on that specific layer causses a search of the pool manager's active pooled objects which may have caused the collision, then find that object's trail renderer, then enable or disable its emission.

#

adjusting maximum distance of raycast seems to help mitgate the jumping line as well, this should work, thanks for the tips

#

I wonder if I can feed the GetComponentInChildren's trailrenderer directly into SetEmitting without the local holding variable

#

Yep! Graphs are...fun?

#

updated graph

grand temple
#

I would recommend an isvalid before trying to do anything like get component

broken bear
#

Safety checks like this?

unknown.png
#

although the second one in the flow would always be true if the GetComponentChildren returns a result, if it somehow passes a null, the first equality check would capture that, so maybe just need the first? (keeping both, just thinkingof optimizations)

grand temple
#

No, isvalid on the object you get from the trigger enter/exit

broken bear
#

Ah I see

unknown.png
#

thanks for the help

feral merlin
#

So is there a way to check the player's ID though? I want to make a room that only I can access

However it only seems to work in CyanEmu, not in VRC itself. The cubes fall right through the floor when I test. Objects can definitely be kinematic in VRC so why wouldn't a kinematics toggle work?

indigo finch
# hoary echo Not really a dev question, but what is the general consensus on re-posting world...

I would post it as a new world. If it didn't get out of the labs, even if you update it, no one will get to see that it got an upgrade unless they have already favourited it (or has a link). You could technically un-publish and republish it, but I don't know if that effects its ability to get out. Btw, as for getting a world out of the labs, I wouldn't recommend updating a world while it's in the labs, as I've found that makes it much harder for it to get out.

#

I think you can watch your colliders toggle on and off in the editor

#

that's why I spend all my time rigging my graphs to work with mouse clicks

#

cause in the editor I can see stuff toggle on and off

#

iirc if your object has physics and a collider and the floor is a collider and they're on the same layer then it won't fall through the floor

vernal magnet
#

By editor do you mean Unity? I can see them toggle there.

paper plinth
#

yeah unity

vernal magnet
#

Yeah, again it works just fine in Unity, it's in VRC that it doesn't.

#

Although sadly the Branch fix didn't work in Unity or VRC.

paper plinth
#

that's not what's wrong then

#

I wonder if there's a vrchat componenet you haven't added or a setting you need to toggle

vernal magnet
#

I tested something and I think I figured out what's wrong.

#

The cubes are pick-ups, and I think the fact I'm toggling off the colliders without toggling off the pickup is interfering with it. To test it I just turned off the collider and kinematic of a cup I have in the world, Built & Tested it, and it fell through the floor.

Edit: Actually that doesn't make much sense, if I toggled off the collider and kinematics is would fall through the floor wouldn't it?

#

Nope that wasn't it. 😅 Well I will either figure it out or just give in and make the cubes kinematic. I appreciate the assistance!

paper plinth
#

oh they are pickups

#

that's different

#

when I try messing with pickups they go flying across the map

#

another thing you can do is replace that gameobject with an identical gameobject that has the settings you want

#

depending on what it is

vernal magnet
paper plinth
#

like if I had an item that the player needed to use, I'd put a dummy there with an interact on it, like a button, and on interact, hide the dummy and put the actual pickup in its place, and let it fall gracefully to the floor

vernal magnet
#

Sadly the object the needs to stay. What I'm making is basically a small photo studio world. The cubes are movable "chairs" that can be used for posing. However depending on if a person has FBT or not, they may not want chairs or colliders. In case the colliders are off, the cubes need to be kinematic so they don't fall.

unknown.png
paper plinth
#

oh

#

you can't just fix its position some other way?

vernal magnet
#

Is there another way to basically tell it 'when x happens don't move'?

paper plinth
#

switch the mass to 0 and freeze the x,y,z position and disable the pickup?

I didn't know we were allowed to instantiate

if i wanted to teleport a player that isnt LocalPlayer, how would i go about doing this. e.g. one player presses a button, it then teleports another player in the instance

fiery yoke
#

The concepts itself are documented yeah. But how to properly use them can get a little tricky. Especially for what youre trying to do. I would recommend to use the "playerID" from VRCPlayerApi and a Synced Variable in Manual Sync Mode.

tacit pasture
#

my plan was to log and create there playerID when they join then call that for the tp

topaz jetty
#

you don't have to create a playerID

#

vrchat has it's own player ID system

#

VRCPlayerApi.playerId

tacit pasture
#

yeah thats what i ment

topaz jetty
#

you can make it sync a vector3 and player ID and teleport them with that

tacit pasture
#

yeah i think that could work

topaz jetty
#

you'd have to make sure that it only teleports them once though, so not every time OnDeserialization is called

tacit pasture
#

yeah

topaz jetty
#

you could make a system with some sort of request ID or something

tacit pasture
#

i think ive got a plan, well see if it works

paper plinth
#

throw an object, like a wrench, and enable the collider when you throw it, and teleport whatever it touches
if you can dodge a wrench you can dodge a ball

#

can I set an objects position below the respawn height to get rid of it / destroy it?

topaz jetty
# 
[UdonSynced] private int playerIdToTeleport;
[UdonSynced] private Vector3 teleportPosition;
[UdonSynced] private int requestID = 0;

{

playerIdToTeleport = player.playerId;
teleportPosition = position;
requestID++;

}

public override void OnDeserialization()

Thanks tho! 👍

#

I'll send a mail to VRChat support if something can be improved about the overall idea about untrusted url

fiery yoke
#

The untrusted urls thing is a temporary solution

#

The original plan was to make it so you can make your own whitelist of trusted domains and maybe even a per world setting or something like that

topaz jetty
#

@stone kelp ok there's a pretty janky solution you could use:

first try loading an untrusted URL on a video player, for this usecase just try loading a short few second video on a local non synced video player so it loads fast

then ```cs
public override void OnVideoError(VRC.SDK3.Components.Video.VideoError VideoError)
{
if (VideoError.AccessDenied)
{
// stuff when untrusted urls is off
}
}

Can someone help me with my udon graph? This is supposed to change the Z Rotation of a cube from the Slider value

dreamy gorge
#

this will not work

quartz meadow
#

what do you mean not work? also quaternions do not work that way

#

depending on what you are trying to do, converting to EulerAngles is probably a better bet

dreamy gorge
#

it just doenst change the Z rotation of the cube object

unknown.png
#

ill try eulerangles

quartz meadow
#

quarternions, as simply as I can put, are a 4 dimensional way of representing 3d rotation while avoiding gimbal lock. you cannot really just modify one of their values and since they are in imaginary space, their math gets weird fast. I suggest you try to convert the quaternion into a 3d euler vector (like the xyz rotation you see in unity), then convert the euler angles back into a quaternion (since thats what an object rotation takes)

#

actually there may be a eulerangles property you can also modify directly

dreamy gorge
#

I found this...

unknown.png
#

if im correct the w axis is world space right?

quartz meadow
#

not quite. seriously, quaternions need quite a bit of a math background to work with, and a lot of reading. I suggest this:

#

there is also a transform -> set euler angles

#

I would actually use that

#

this takes a vector 3, so you are gonna have to make a vector 3 first

dreamy gorge
#

I have this now

#

oh wait

yup, I think this should work better

#

maybe this wpould work better

quartz meadow
#

I think very simply stuff may be easier to make in udon graph, but at a certain point for large projects, udonsharp is the way to go

unity c# will not compile for vrchat

since it has access to system fileio and stuff

which, obviously wont end well

VRChat
Debugging Udon Projects

What is Debugging? Debugging is how you learn about what's going on under the hood in the VRChat client and your world. It's a key skill to develop for programming in general, and for building your worlds. VRChat Logs When you use the VRChat client, it saves logs about things that happen like worlds...

#

Shift + Backtick + 3

dreamy gorge
#

Where do you use that combo?

quartz meadow
#

keyboard, even in vr

#

you can also just go to your appdata/LocalLow\VRChat\VRChat folder

#

logs will be saved there as well

dreamy gorge
#

lmao

#

are these all error things?

#

or just normal logs

quartz meadow
#

all of them are total vrchat logs, check your most recent one, and search for this line

#

[UdonBehaviour] An exception occurred during Udon execution

#

if your code errored, it will spit some stuff here

#

if it doesnt show up, it means your code didnt error, so I would likely pin it on not starting at all

dreamy gorge
#

i can see that it starts in unity when i test it

quartz meadow
#

oh, you are testing in unity itself?

dreamy gorge
#

yes

quartz meadow
#

so, unity itself, interestingly, cannot run vrchat script, but there is a work around

#

import this, it is a vrchat emulator for unity

#

basically, it will make the play button work as expected

dreamy gorge
#

ah instead of putting you in the camera

quartz meadow
#

yeah, it will give you a dummy capsule avatar to go around and stuff

#

you can also click and do most thing desktop players can

dreamy gorge
#

How do you install that

quartz meadow
#

its discussed in the getting started section. basically, just download the file and in unity, go to assets, import package, custom package, and select the fil;e

#

it will take a minute or two

dreamy gorge
#

oh lol i shoud've read that my bad

quartz meadow
#

no worries

dreamy gorge
#

oh theres releases

#

i though i had to compile it into a package or something

#

nah, its pretty straight forward. after that, your play button will work, and you can walk around, test buttons and stuff

dreamy gorge
#

oh btw the errors are the same in unity

#

its not too helpful
