udon-general

[manic yarrow]

I've got the timesincelevelload set up

[grand temple]

to the same number every time, or to something else?

[manic yarrow]

so I can set it to -1

[grand temple]

oh, you need a float const node

[manic yarrow]

Networking IsOwner next, right?

Not sure

[grand temple]

yeah, just a series of branches to make sure that every case is observed before doing the respawn

[manic yarrow]

hmm, about that owner check

What if someone else grabs a seat you're in?

[grand temple]

then it will transfer to them and they will do the respawning

but they'll still receive the onenterstation from you, and so the float will be -1 and they won't respawn it until you get off

[manic yarrow]

Which node outputs parents to an obj?

[grand temple]

transform getparent

[manic yarrow]

I tried that one, it doesn't connect to IsOwner

unless there's more than one IsOwner and I haven't noticed

[grand temple]

isowner expects a gameobject

so you can just do transform get gameobject

[manic yarrow]

This is what I've done so far, I know I need to connect the gameobject up

or do I?

It should be getting it from the getparent at the start, no?

[grand temple]

this part is not correct. You're checking if timer is greater than timer + 30 but that will always be false. You need to check if time.timesincelevelload is greater than timer + 30

the ownership check looks good

[grand temple]

yep

also make sure you're plugging something into objectsync respawn. Easiest would be getcomponentinparent (vrcobjectsync)

[manic yarrow]

Does it have to be blank?

I have one in this graph but the type is set to vrc_pickup

[grand temple]

what, getcomponentinparent?

[manic yarrow]

yeah

it's set to type with pickup attached

[grand temple]

the instance there can be blank because it's just looking for a transform. Transform, gameobject, and udonbehaviour will always self-reference in graphs if left blank

[manic yarrow]

So I should make a new one

[grand temple]

I'm not sure what you're asking

[manic yarrow]

I was just trying to re-use a node I already have

but it has a type attached to it

I wasn't sure if that would affect it

[grand temple]

yeah you don't want to directly re-use it because it's not the right type. But you could copy it and then change the type

[manic yarrow]

which type?

[grand temple]

vrcobjectsync

[manic yarrow]

alright

[grand temple]

that's what respawn is looking for

[manic yarrow]

So will that cover both sitting and picking up?

[grand temple]

oh right, you'll want to set the float to -1 onpickup and time.timesincelevelload on drop as well

[manic yarrow]

How would I refer to the parent in that scenario?

since I can't attach anything to events

[grand temple]

the parent has the onpickup and the child has the timer float. So just have onpickup > getcomponentinchildren (udonbehaviour) > setprogramvariable "timer"

or you could rearrange it so that the variable and the update loop is on the parent, that may make more sense

[manic yarrow]

The reason it's on the child is because there were some issues with it being on the parent

I can't remember what the issue was, but having the script on the seat fixed it

[grand temple]

like what, being able to detect onstationenter?

[manic yarrow]

that might have been it but this was a few days ago now

[grand temple]

you can't detect events like that happening on a separate gameobject. That's why you put a script on them and then send the events or the variables back to another script. You're going to have to communicate between them somehow

[manic yarrow]

I feel like the way you suggested is easier

[grand temple]

I would also just recommend having public udonbehaviours on each to refer to eachother instead of doing getcomponent all the time. It's not a huge deal since you're not doing any of this every frame, but it does reduce the number of nodes going on and also allows you to make use of the fancy dropdowns on setprogramvariable and sendcustomevent

getcomponent is relatively expensive because it has to look for things by checking a bunch

[manic yarrow]

I assume I'll need to make the timer public now

[grand temple]

yes

wait I mean no

setprogramvariable can set private variables

in udon, public really just means that it will show up in the inspector. Which doesn't exactly match C# but oh well

[manic yarrow]

yeah, that's what made me think I'd need to

so just make a variable with the same name then?

[grand temple]

if you want to move it, yes. If you want to set it on another udonbehaviour, no

[manic yarrow]

It's just that I don't see how I'm meant to refer to it otherwise

[grand temple]

setprogramvariable

if you have the udonbehaviour as a public variable, it will populate the dropdown with that program's variables. If you are still using getcomponent, you have to plug in a string const and make sure it's spelled exactly the same including capitalization

[manic yarrow]

oh, it's just a string

alright, I think that's everything

[grand temple]

no, the instance is left empty so that will refer to itself

you need to do getcomponentinchildren (udonbehaviour)

[manic yarrow]

I don't see it under udonbehaviour

[grand temple]

I mean gameobject getcomponentinchildren, then plug in the udonbehaviour type

[grand temple]

no, not that

[manic yarrow]

wait

it must've corrected

just noticed it's the wrong node

[manic yarrow]

yeah, I typed "type" a little too quickly

I dunno

with that swapped, is that everything?

[grand temple]

yeah probably

[manic yarrow]

Just to be sure, what happens when the world starts and nobody has touched anything?

[grand temple]

oh yeah, you probably want the default value to be -1

but worst case it would just respawn to where it already is ¯_(ツ)_/¯

[manic yarrow]

I suppose having an object teleport an inch every 30 seconds isn't bad

[grand temple]

well after respawning it, you want to also set the variable to -1 otherwise it will be respawning every frame

[manic yarrow]

So I just tack that on the end of the script

[grand temple]

on the update loop, yes

[manic yarrow]

would it be better before the respawn? I don't know how it works but I can imagine it might have the chance to trigger a few times

[grand temple]

it does not matter since everything that goes through the flow happens instantly. There is no possibility for udon to execute this twice before it's finished once

[manic yarrow]

Oh right, white line and all that

[grand temple]

if you have some really complicated math that takes time to do, it will freeze the game entirely until it is finished

[manic yarrow]

I was thinking about lag and stuff, I used to write E2s for garry's mod and sometimes you'd have to account for that kind of thing

[grand temple]

yeah, then it probably ran on multiple threads and so you can have different threads doing different things or even the same thing at the same time. But udon at the moment always runs on the same thread, so performance is worse but it's much easier to keep track of everything

[manic yarrow]

VRChat needs multithreading joke goes here

[grand temple]

plenty of other things are multithreaded, especially constraints, networking, and voice transmission. Making code that is multithreaded is one thing, making a VM that allows people to make their own multithreaded code is another thing entirely

[manic yarrow]

am I missing something? doesn't seem to work

sync mode, anything like that?

[grand temple]

pics?

any udonbehaviours crashing?

[manic yarrow]

first one is on the seat, second one is on the pickup

neither of them cause a respawn after 30 seconds

just in case, I'll compile again and make a new build

maybe it just didn't apply

nah, didn't help

[manic yarrow]

everything compiles just fine too

[grand temple]

not crashing on compile, I mean crashing ingame

check your logs

ah, vrcobjectsync GetType is not correct. That's asking for a vrcobjectsync and will give you the objectsync type which is... not what you want. Probably one of those weird auto-generated nodes that isn't really useful.

Instead you need VRCObjectSync Type

I tried looking and I have no idea what folder this node is in, but again if you don't know where it is you can always find it in the full search with tab!

[manic yarrow]

it works when you sit, but not when you grab

[grand temple]

sounds like the script on the pickup is crashing from something

[manic yarrow]

I can send you the log if you want

[grand temple]

you can look at it yourself, just search for "halt"

[manic yarrow]

no halts

[grand temple]

ok, then it's not crashing. Try adding a debug log after the setprogramvariable to make sure that's happening

[manic yarrow]

what should I search for?

searching "debug" didn't do anything

[slim hound]

Searching for "Log" should bring it up as the first option

[manic yarrow]

inside the log itself?

[slim hound]

They are nodes in the graph that you add to debug your udon programs

[manic yarrow]

I've added them already

I'm sifting through the last game's log

[slim hound]

You should just be able to search for whatever string you were logging

How do you have the log in the udon graph setup?

[solemn talon]

Anyone got any ideas for raycasting to detect the presence of a player?

Right now what I've tried is the box collider on a canvas UI from this article on player tracking http://vrchat.wikidot.com/worlds:guides:player-tracking

My layer mask includes both the Player and UI layers but the ray doesn't seem to work with players, at least in "Build and Test"

[manic yarrow]

the log was triggered twice, once when I picked it up and once when I dropped it, so it's doing everything without a hitch

[slim hound]

What's your current setup, that article is probably not the best thing to follow as it's for SDK2

[solemn talon]

SDK3 and Udon

[slim hound]

Yeah I was asking more of the udon behaviors and how they are set up

[solemn talon]

Basically just raycasting in the forward direction from a GameObject

[slim hound]

If you were trying to follow that article it would be a fairly roundabout way to do it in udon

[slim hound]

So does each player have their own raycast or does each player have their own collider?

[solemn talon]

Each player should have a collider that is detected by a raycast

And blocked by objects on the default layer

The raycast is blocked I mean

[slim hound]

So do you have an objectpool that assigns them to each player?

[solemn talon]

I haven't done that, I associated the canvas element with the main camera, I thought that would populate it

I can give that a shot though

Basically just what that article said, but with a bigger box collider

[slim hound]

Udon has built in functions to do all of that without the roundabout methods

You should ignore that article since you are using Udon

If you have an object pool you would assign an object to each player and give them ownership of it, then in the graph get owner > get position of owner > move game object to that players position

[solemn talon]

I'll start working on trying that out, just to be clear I create a pool of GameObjects collider components on an appropriate layer that no actual collisions happen, assign them to players as they join, then raycast against the GameObjects that are on each player? With the GameObjects updating their position every tick?

[slim hound]

Yeah, for the raycast though you would need to use a networked event or alternatively have an object pool for giving players the raycasts also

[solemn talon]

Cool, sounds promising. Thanks for your help!

[manic yarrow]

Can you see anything wrong here node-wise?

[slim hound]

I suppose it looks fine but I have never used GetComponentInChildren

I prefer GetChild as you can give it an value of which child specifically

Though you only have one game object as a child right?

[manic yarrow]

yeah

wait, 2 actually

one of them is a seat entrance point

[manic yarrow]

suppose I manage to make it work with just 1 child, what would I do?

[slim hound]

That graph you sent should be fine

The other part is probably where the issue is

[manic yarrow]

that other part works perfectly for what it does

all that second graph does is poke some new values in

[slim hound]

What does the respawn function look like?

And to clarify that is the part that isn't working right?

[manic yarrow]

This part works great for the seat (which is what the script is attached to)

so things respawn correctly 30 seconds after getting out of the seat

but the other part is what's wrong

[slim hound]

Wrong how?

[grand temple]

can you just try using public variables instead?

[manic yarrow]

That's what I'm trying to work out

all I know is that it doesn't do what it should, and instead does nothing

[manic yarrow]

do you just make a new variable under the same name?

[grand temple]

I mean to replace all the getcomponents

manually define exactly what you want to do instead of just assuming that it's set up a certain way

[manic yarrow]

On both scripts?

[grand temple]

yes

[manic yarrow]

I'm back, PC was nagging me about updates and stuff

I realised something though

Is there a chance that the pickup script could be interfering?

[grand temple]

you're going to have to get it the rest of the way yourself. There's a lot you can do to find out why it's not working. Try logging every step of the way in the update loop so you know where which part is stopping. Try logging the variable so you know what's happening. Try logging the name of the gameobject you get from getcomponents so you know for sure it's getting the correct thing.

[burnt moth]

trying to make a toggle where you click it and npcs disappear and appear, like On/Off but for multiple objects and this isnt working so far

I’ve read so much and tried to learn but it doesnt work

[slim hound]

You would want to do this

[burnt moth]

alright I’ll try it later thanks

[burnt moth]

they wont turn on again if I click the button

They turn off and then they wont turn on anymore

[slim hound]

Show graph?

[slim hound]

In the inspector in the object array you don't have any missing elements do you?

[burnt moth]

what do you mean by that

you mean the array where I put the things turned off and on

[slim hound]

Yeah

[burnt moth]

no since it's turning off properly

there is something with the graph or something

the sync method is contineous

the first time I click it, it's doing what it should, but the npc's wont come back when I click it again

[slim hound]

Are you testing in game or in editor with CyanEmu?

[burnt moth]

I built test it

with the skd

sdk

[slim hound]

https://github.com/CyanLaser/CyanEmu/releases/tag/v0.3.9 Get this and test in editor play mode

[burnt moth]

but it didnt work in vrchat

[slim hound]

Yes that will make it easy to figure why it didn't work

[burnt moth]

someone told me to make a bool to fix my array

maybe thats why

he told me to do this

but I didnt understand how

[slim hound]

What are the NPC objects you are toggling?

[burnt moth]

just npcs

like gameobjects

[slim hound]

Can you change the udon behavior to toggle a couple of cube game objects instead and see if that works?

[burnt moth]

okay I'll try

[burnt moth]

yeah the cubes work

the thing I am trying to disable is a trigger with the model as a child so I disable both the trigger and the model

cause it would be weird to speak to a non existent npc

[slim hound]

Yeah that's kind of what I figured

Something with the NPCs is changing when you toggle them

If you get CyanEmu you can test in editor and see what is happening

Or you could just go into play mode and toggle them manually

[burnt moth]

hmmmmmm

I'll try and see if it works if I seperate them

like not being parents and childs

then I'll try like you said

[burnt moth]

@slim hound this fixed it

thanks for the graph!!!!!

you are a lifesaver

[burnt moth]

is it possible to make a working boat that you can drive

basically just a car but just shaped as a both or used a finished model and add some sort of graph to it

[cold raft]

that is already posable

you could look up varneon on yt he makes realistic driveable cars

[burnt moth]

okay

I am also wondering if it possible to make where u click on a toggle and an animation plays, but you can only press it once and then you gotta wait until the animation finishes or a certain time before being able to toggle it again

for some reason when I jump avatar pedistals like go invisible but when I am on the ground I can see them

[cold raft]

Yes you can disable buttons for x time while animation is playing

this disappearing when you jump has todo with culling to over aggressively

[hushed gazelle]

If I Destroy a synced gameobject, does it destroy it for all players or just locally?

[grand temple]

just locally

[pure parrot]

hey guys , i did a small graph to change the colour of an object when a player step on it . I put a cube as trigger but nothing ever happens and idk why . I don't think that the animator part is falty since i tested this specific part and it was working

[slim hound]

Wrong events, you will want to use OnPlayerTriggerEnter/Exit

[manic yarrow]

What counts as an update to the update event node?

[pure parrot]

many thx 👍

[grand temple]

update happens every single frame

[manic yarrow]

ah, that throws a theory out then

I was thinking that whatever I was doing on the external script wasn't counting as an update

as if an update happens when there's a change of some kind

[pure parrot]

Is it possible to only use 1 OnPlayerTriggerEnter event for multiple SetBool ?

I'm making multiple trigger zone and Idk if I need to make a graph for each one of them or just making a single graph for everyone

[slim hound]

Can you explain a bit further as to what you want to do?

Also in your use case it might help for you to know that OnPlayerEnterTrigger will trigger whenever any player enters the area not just the local player

[pure parrot]

I want to make a system where I can detect how much person there are , there's 8 platform and when a player step on it the colour goes white to green , if the player isn't on it anymore it turns back to white

Thinking about it this is extremely dumb , I could just make a graph for the material switch part and then do something to count how much person there is when someone press a bouton

problem , idk how to do that

[slim hound]

You could use the OnPlayerTriggerEnter to count how many there are too

You would just need to branch for either local player or master

[pure parrot]

what's the use of knowing if the player is local or master ?

[slim hound]

Otherwise everyone will add to the number when they see someone EnterTrigger

So one player entering will add 5 if there are 5 people in the world

[scarlet lake]

how do i make where if you throw a object of the map it respawn

[slim hound]

Adding an object sync component will give it that behavior

[scarlet lake]

also what making a object bounces

[slim hound]

On the collider you add a physics material

[scarlet lake]

this ?

[slim hound]

In assets right click > create > physics material

On that material make it bouncy

[scarlet lake]

i meant for when it falls off

[slim hound]

Falls off?

[scarlet lake]

so say the object gets thrown off or bounce of how do i get it to respawn

[slim hound]

Add an object sync and if it falls out of the map it will respawn

Other than that you would do ObjectSync.Respawn or transform set position to move it back

[scarlet lake]

what do i add nexted

[slim hound]

#udon-general message You could go back through this conversation as it explains a lot about respawning an object

[scarlet lake]

what is timer and single under

[pallid mango]

Local player means yourself. Everyone in going to have a different opinion on who is local. This is important for when you want something to only trigger for you but not when you see someone else do a thing

Example: a jump scare in a horror map. lol

Master - I have not had any use for this in udon. Useful if you want the person who has been in the room the earliest to have special abilities I suppose

[scarlet lake]

also i have the udon timer but i dont see just timer

because in this it say timer but when i try to find its no were

[pure parrot]

ok thx for the answers

[scarlet lake]

?

[scarlet lake]

how do i get the single and timer when have the udon for it

[slim hound]

They will be under float

[floral dove]

timer is a Variable in this graph, you need to create it

[scarlet lake]

ok so i ran into a problem where i have to add this in order for it to connect

[slim hound]

If you are very new to udon it might be worth to watch a few tutorials of the basics

[scarlet lake]

im not the new

its just lol im stuck on this part

[scarlet lake]

but if you have video for i mean that could help

[slim hound]

Just watch some of these to get a better understanding of what things do https://www.youtube.com/watch?v=7yuj7X0-OuI&list=PLwEtUGCdQX7HMkFCVxiNvO4DS2CmHWbe6&index=9

[scarlet lake]

i watched that already it didnt help thats what i looked before coming to u guys

[cunning mist]

You're doing "Get ComponentS" instead of "Get Component." You're likely only looking for one.

[scarlet lake]

does this look right

[cunning mist]

So that I can get a quick breakdown, what is it you're trying to do?

[late belfry]

anyone know why pool tables cause my FPS to drop to 10?? please help

[pallid mango]

Some of them might be older. Newer versions are far more optimized

[late belfry]

i am the only one in the room fps drop

is it my 3090???

[floral dove]

Is this a world you're creating? This channel is for creators looking for help and feedback on using Udon.

[late belfry]

ohhhh. ok. thanks

[scarlet lake]

How do I make the pick able object global

[floral dove]

https://docs.vrchat.com/docs/udon-networking

[scarlet lake]

so

i dont get it

[cunning mist]

Add the "VRC Object Sync" component, and that will sync your object's movement and physics to other players.

[hybrid fossil]

A question.

Is Udon applicable to VRC worlds, or can it be used for setting up unique animation for avatars as well?

[cunning mist]

Worlds only, though you can do a lot through Avatars 3.0!

[scarlet lake]

where can i find this under

[grand temple]

that looks like a variable, but it's very very old. Nowadays variables are added in the floating window on the left with the plus button

[scarlet lake]

because this udon im trying to make

[grand temple]

if that's a picture from your own graph, make sure you have the latest SDK. If you're following a tutorial, find a more up to date one

here https://www.youtube.com/watch?v=O3VeBzV9HgI

[compact snow]

Anybody aware of the workaround for Dropdown.AddOptions? I'm trying to dynamically update the dropdown menus but udon doesn't support List types, so i can't ? (forgive the noob)

[grand temple]

Unfortunately no, you cannot

[compact snow]

☹️ bugger

[grand temple]

Best you can do is create your own version of a drop-down out of buttons, vertical layout group, and instantiating

[compact snow]

hooo baby -.- I'll er.. consider that. thanks Phase

[feral valve]

Just asking if possible. Can you make a box collider not allow portals to be placed in them? I don't see it as a feature and curious if it can be done with udon by deleting it or straight up not allow it

[feral valve]

though if it is possible how can I make one

cause idk how you can get a gameobject thats spawned and delete it

[slim hound]

The most reliable way of preventing portal drops is using spawn points

If you make the box collider an assigned spawn point on the scene descriptor it will give users the "Portal too close to spawn" message when they try to drop one

You may need to have multiple depending on the size of the box collider

[feral valve]

I was hoping I could just scale the collider and it work. but I guess I just have to useless spawn points. only testing

Hopefully there's another way

Or a way of discouraging it like respawning them

[obsidian solar]

Is this still a feature? I'm trying to create an object that can be held in 2 places.

[flint urchin]

It will make the entire root + children part of the pickup points (as one)

If you're aiming for a two handles type of pickup, you need to handle that differently

[fiery yoke]

Is there a way to "Unload" a Video Player? Basically I just want to release the resources on demand.

[obtuse agate]

videoPlayer.Stop() ?

[fiery yoke]

Stop doesnt unload the video. It simply stops playback.

[floral dove]

Stop should release the resources, at least for the Unity Video Player
https://docs.unity3d.com/2018.4/Documentation/ScriptReference/Video.VideoPlayer.Stop.html

[fiery yoke]

The weird thing is that youre able to Play() after Stop() which plays the video

So does it "remember" the last video and fetches it again?

[floral dove]

Hm - there's not a direct 'callback' pattern available, but you could have a variable that uses an OnVariableChange event - pass that into another program, and when the variable is changed your first program will receive an event with the updated value

it's more like C# properties than callbacks, but may get the result you want

[manic yarrow]

How can I set a variable in a udon graph using a separate udon graph? I've tried setprogramvariable attached to getcomponentinchildren, but that didn't seem to work too well

[obtuse agate]

https://docs.unity3d.com/ScriptReference/Video.VideoPlayer.Stop.html

This also destroys all internal resources such as textures or buffered content.

[fiery yoke]

I use a pattern where I have an array of UdonBehaviours that acts as a "subscriber" list. When an event happens, I iterate through the array and do a SendCustomEvent to all valid Behaviours in the array. I use the array as a ring-buffer with an additional indexing integer that overflows at Length back to 0 and increments whenever you add a behaviour and skip over nulls unless no slot is available.

However this only works for events without parameters.

[fiery yoke]

Hmm weird. As I said, you can Play() after Stop() and it will just work

[floral dove]

Yeah - Play() will prepare the media for playback again https://docs.unity3d.com/2018.4/Documentation/ScriptReference/Video.VideoPlayer.Play.html

[fiery yoke]

Ahh I see it works because the actual video file is kept in a temporary memory somewhere.

[pallid mango]

That is how you do it yes. The set program variable needs a reference to the actual udonbehavior though. Also when selecting the variable name from the drop-down there’s currently an off by one error. The name of the node is the variable you are modifying not the name in the drop-down

[manic yarrow]

There's a drop-down?

I'm on the latest SDK and I've not seen that

This is what I tried last

It was suggested to me to use public variables, but I broke something in the process and reverted

[swift jolt]

Is there anyway to detect if a player is crouching in udon?

[normal yarrow]

Does anyone know a good way (or asset) to make good looking volumetric spotlights that are VRChat compatible?

[manic yarrow]

have you tried asking in #shaders? I feel like you'll have better luck there

I've definitely seen volumetric shaders before

[normal yarrow]

Ahh, yeah that does seem like a better channel to ask in

[valid oar]

I'm working on a world where I want people to be able to move forward and back through pages of text using text objects that appear and disappear in a sequence. I would imagine this would be done via an array that would store the various game objects and then hide the game object at the current element and show the one at the previous or next element depending on whether the button to go forward or back was pressed. I think that's how it would be done but I don't know how to translate that to Udon. I know there's a prefab that allows for different materials to be swapped so I could do it that way but that only goes in one direction and using text objects seems like it will use a lot less space than having a bunch of materials with their own textures.

I could hard code it so if I press the forward button on page 1, it has a script that hides page 1 and shows page 2 but I'm planning on having dozens of pages and making a separate script for each wouldn't be ideal if I can avoid it.

[floral dove]

take a look at the 'Chooser' in the UdonExampleScene, it does this with the demo prefabs

synced, even

[valid oar]

I will do that, thanks.

[uncut tusk]

i have a question, anyone know how i can make a Trigger for Toggle GameComponent ? Like when i Trigger it, it will turn off the Animator inside the Object but the object stay On.

[floral dove]

Sure - you can make the Animator a variable and then control it's 'enabled' value or have it Stop()

[uncut tusk]

waht you mean exacly? i have my little problems with the Udon Graph 😅

[floral dove]

How far have you gotten?

[uncut tusk]

Not very far xD I can't even create a simple trigger without help😅

[floral dove]

ok - there's a ToggleGameObject program on the MirrorSystem that demonstrates turning an Object on and off. Can you get that working first, then we can change it to make it control an animator instead?
https://docs.vrchat.com/docs/udon-example-scene#mirrorsystem

[uncut tusk]

I don't need that for an animator to be honest. I want to insert a button that allows you to turn a pressable button into a clickable one. depending on the user is in VR or desktop

[floral dove]

Ok - the example here will show you how to use the 'Interact' event to make any object clickable and run some logic, that's a good place to start: https://docs.vrchat.com/docs/udon-example-scene#interactcube

[uncut tusk]

okay thanks i hope i can work with that

[floral dove]

once you know how to use the Interact event and you have that working, you can then add an Animator variable and control that instead

[manic yarrow]

@grand temple I finally got it all working, although I noticed a minor issue

If someone is sat in the seat and then someone picks it up and drops it, the 30 second timer starts back up and the seat will respawn with a player sat in it

this is what I ended up doing, a public variable that points directly to the seat like you suggested

[grand temple]

so add a bool for when it's currently being sat in and don't set the float if so

and likewise for being held while getting out of the chair

[manic yarrow]

station seated, right?

[grand temple]

yeah

[grand temple]

you're just allergic to public variables aren't you?

[manic yarrow]

I tried using the public variable I already had, wasn't sure how it could connect

[grand temple]

is it a vrcstation variable?

[manic yarrow]

It's less that I'm allergic to public variables, and more that I'm allergic to knowing variables have types

[midnight beacon]

Has anyone had this problem? Vector types wont display properly, they're totally busted

[grand temple]

just reload the graph at the top right

[midnight beacon]

Tried, no dice :C

(using 2019 btw, I should mention that just in case)

[grand temple]

oh that bug, yeah it's known and will be fixed soon

[midnight beacon]

Oh okay, thanks for the heads up o7

[grand temple]

actually wait, what kind of constructor is that?

[midnight beacon]

MeshCollider, but the display issue happens on basic Vector3 types

[grand temple]

vector3 constructor looks like this to me

meshcollider constructor isn't a thing

[midnight beacon]

I should reword, I was trying to construct a ray with the box that was broken

[grand temple]

ray constructor looks like this to me

[midnight beacon]

Yeah, the X boxes stretch horizontally to the point where everything to the right is pushed out of the node canvas

[grand temple]

let me double check with the latest SDK

[grand temple]

ohhh it's a vector3 const node, not a constructor

[midnight beacon]

Theres both a ray constructor and a Vector3 node thats busted

Seems to be whenever theres more than one column of values

[grand temple]

ok, thanks. That one is slightly different to the other issue so it was not on the radar

[midnight beacon]

Hooray for finding bugs. I was hoping this might be some common simple fix thing which is why I asked here first but thanks for discussing this with me, ill see if I can get it reported if I can't fix it.

[grand temple]

already thrown it in the pile, don't worry about it

[midnight beacon]

Oh, much appreciated ^-^

[grand temple]

if you need a workaround for now, though, it should work if you just plug public variables into the slots

if the slots have something plugged into them they won't display the full inspector so they will properly display the output

or if you want to define it in the graph instead of the public variables, you can use a vector3 constructor node

[manic yarrow]

Is get seated definitely the right node?

I just tested it with a friend and they still respawned

[grand temple]

probably, but it may only work for the local player

[manic yarrow]

I'm asking because "seated" is a checkbox on the station script itself

I don't think it's related to whether someone is in the seat

but I can't be sure

[grand temple]

oh yeah you're right, that's a property that changes how you attach to the station

[manic yarrow]

Hmmm

[grand temple]

just set a bool onstationenter and exit

[manic yarrow]

alright, give me a moment

[feral valve]

Thought I'd try asking again. Anyway to delete created portals in within a collider?

[grand temple]

you mean you want the world to prevent players from placing portals in a particular location?

[feral valve]

yeah

[floral dove]

The most reliable way of preventing portal drops is using spawn points
If you make the box collider an assigned spawn point on the scene descriptor it will give users the "Portal too close to spawn" message when they try to drop one
You may need to have multiple depending on the size of the box collider

[feral valve]

So there really is no other way

[grand temple]

you can also just prevent placing any portals anywhere in the vrcworld

[feral valve]

box collider didn't change anything when I tried it.

[grand temple]

but if you want to deny a specific location, then yeah I'd recommend spawn points

[feral valve]

spawn points I'm guessing only cover 4 square meters

So how would I make them not a actual spawn point

[grand temple]

udon has an onrespawn event, so when that happens just teleport them to where you really want

oh, onspawn not onrespawn

[feral valve]

alright, ty

[floral dove]

you can have the Spawn Order be 'first' and put your portal-protection spawn points after the first one

I think? Never used anything but 'Random' for Spawn Order

[manic yarrow]

How's this? the seated bool is set by the onenter and onexit in the other graph

[grand temple]

you're setting it to -1 onpickup, so that's not the one you want to block if they're seated. You want to block the one that's causing it to actually get respawned, which is the ondrop

[manic yarrow]

oh, right

[grand temple]

yup

and add the opposite to onstationenter

[manic yarrow]

what if someone sits and leaves?

[grand temple]

while someone is holding it?

[manic yarrow]

now you mention it that's a very specific set of circumstances

[grand temple]

the time will be set by whichever event comes last

[manic yarrow]

does quitting VRChat count as onstationexit?

[grand temple]

I have no idea

[manic yarrow]

Hopefully it does

otherwise it's possible for someone to sit and then quit

and then that chair is technically being used the whole time

(until someone else sits in it)

[grand temple]

That's not what you want. Setting it to -1 prevents it from respawning. If you pick it up, you always want to prevent it from respawning

[manic yarrow]

Is that in reply to the graph I just put together?

[grand temple]

yeah

[normal yarrow]

I notice that when I play an audio stream online and I put an effect, like reverb, all of a sudden the volume is maxed out and it can't be changed

Seems like a bug?

[manic yarrow]

so which way should the branches be?

[grand temple]

onpickup and onstationentered shouldn't have a branch at all

[manic yarrow]

I thought I needed that to check if the seat is being used

since I've got this bool that determines if someone is sat down

[grand temple]

yes, but you're using that to prevent it from being respawned when someone is sitting

picking it up doesn't start the respawn timer, it stops it

[manic yarrow]

I'm still not sure what you meant by "add the opposite to onstationenter"

[valid oar]

Is there a way to set all of the objects in an array to active? I tried reverse engineering the chooser script and came up with this but it doesn't appear to work. Do I need to cycle through the array and enable all of the elements individually or can they be handled as a group?

[cold raft]

you need a for loop

alternatively you could put all objects under the same parent in the hierachy and toggle that parent instead

[valid oar]

Unfortunately they need to be parented to different objects because those are all in another array that is being controlled by the chooser from the Udon Example scene. I have a very limited background in programming so I know how those work but not how to create them with nodes. Is there a tutorial you could recommend for that sort of thing? Most of the tutorials seem to either be very basic or focused on advanced networking.

[cold raft]

yeah udon tutorials are indeed either basic or advanced 😄

so kinda like this

[valid oar]

That's great, really appreciate it. It kind of even makes sense at a glance which is always nice.

[stark adder]

Is there anyone having this same problem ? where the Upload just fails MID upload like 50 times before I can finally upload it ? It gets really annoying

I am starting to go little crazy 😵

[gusty tusk]

Is Udon running c# code in real-time or does it get compiled like when Kotlin compiles Kotlin code to java code? And since if there's another high-level added, how much of a performance decrease would it be if i wrote in c# rather than using the Udon system?

[cold raft]

So both udon graph and udonsharp compile to udon assembly using IL2CPP, so udon# will be just as fast as udon graph

[gusty tusk]

Any overhead (comparing to before Udon) to keep note of? Thanks for all the replies!

[cold raft]

well udon is not as fast normal c# as there is indeed overhead on it but there is no way around that for vrc your only scripting abilities are udon, still udon is quite powerfull i never found it slow

[gusty tusk]

Ah, bummer. Cheers!

[blazing timber]

I want to teleport the player who toggled the button with their names on it. So far I made a udon can get the displayname who interact the button, but it’s only work locally. Need help.

[cold raft]

why do people keep implementing on ownership transfered

anyway what you need todo, isa syncronised variable of type string that you call like displayname
and instead of setting the text directly you should change the value of displayname and than request serialisation
then you need to alt+drag that new variable to create an onchanged event for that variable and in there you can update the textfield

like this

[blazing timber]

Thanks a lot, didn't notice I haven't update my SDK...

[cold raft]

Ah yes the variable changed stuff is very recent

[stark adder]

Is on variable change executed even when variable is not changed (manual sync RequestSerialization)

[cold raft]

I never tested that, but it would be pretty wierd if that is the case

[floral dove]

it's only executed if:

• You change the variable with SetProgramVariable
• You change the variable with SetVariable and 'sendChange' turned on
• The owner of the object changes a synced variable using one of those methods

[swift jolt]

Is there anyway to detect crouching in Udon?

[slim hound]

Not directly but you could likely detect it fairly accurately on a humanoid avatar by checking bone positions/rotations

[swift jolt]

Sounds good. Thanks

[keen socket]

So, I've looked everywhere and can't find any good info on timers. I need a simple timer that after a collision waits x time and the continues on the graph. Watched a video or two, but was looking more for documentation... of some sort. Any info would be great 😉

[grand temple]

you're looking for sendcustomeventdelayed

[keen socket]

yee! thanks

[sacred thicket]

Hello, I have a little question: Is there a node in Udon that is basically the C# equivalent of "WaitForSeconds" so I can for exemple play a sound then wait 1 second and then teleport the player?

Oh wait, I think the question above answers it X3 Sorry!

[random orbit]

Guys I cant seem to find (transform.set position)

[floral dove]

type Transform, press Enter, type setposition, press Enter.

here's all the ways you can search for nodes @random orbit: https://docs.vrchat.com/docs/searching-for-nodes

[random orbit]

Thank you

[random orbit]

Im having some issues with a graph that i made for some reason the door doesnt move but you can walk through it like hit has opened

[grand temple]

is the door's gameobject set to static?

[random orbit]

Yes

[grand temple]

disable that

static means it shouldn't move

[random orbit]

Bruh

Aight im pissed Thank you

[scarlet lake]

Does anyone know how to keep a player stable on a platform? Thank you, if you can help

[floral dove]

the only way I know of is to put them in a station

[scarlet lake]

Can you please show me, I’m trying to make a subway train and through the seats a do-able I want people to be to walk within the collision mesh

[floral dove]

there's a demo station in the UdonExampleScene that shows how to put a user in a station: https://docs.vrchat.com/docs/udon-example-scene#vrcchair3

[scarlet lake]

Ahhh thank you for your help

[normal yarrow]

Does the regular Unity Video Player component work in VRChat?

[floral dove]

you need to use our special wrapper for it - full details here: https://docs.vrchat.com/docs/video-players

[normal yarrow]

Oh I see, I wanted to play a local video, which I didn't see the option to use on these ones.

[floral dove]

not currently supported, sorry

[normal yarrow]

Oof, that's unfortunate.

Guess I'll need to find a workaround.

[floral dove]

The workarounds are listed on that page! You can host it on a server and provide a direct URL link, or use one of our supported video hosts.

[normal yarrow]

I need local videos cause I need movie graphics for WWE entrances in my arena map, if I used those, I wouldn't be able to load all those graphics at once because of the rate limit.

(For context)

[floral dove]

right - if you want to have multiple videos playing, you'll need to queue them up with 5-second-ish delays when someone joins

[normal yarrow]

Yeah that unfortunately wouldn't work out, it'd take too long for all the graphics to change.

[floral dove]

how many different videos are you trying to load at once? Could you combine them into one?

[normal yarrow]

5 graphics.

1 for the main tron, 1 for the mini trons below, 1 for the floor ramp tron, 1 that's used on the ring apron and ring corner post trons, and 1 that's used on the side stage (and arena ribbon) tron.

If I could put them all in one, that would make sense, but the each of the graphics usually has their own different time length, making looping very difficult

Quite the sticky predicament I'm in.

[floral dove]

oof - you're likely to suffer a pretty big performance hit trying to play 5 videos at once on most machines. You could instead put them all in one video and split it up using UV mapping to have it play on the right sections of your models.

if they're very short, you could try turning them into sprite sequences and playing them through animators, but that can take quite a performance toll as well

[normal yarrow]

Hm...

Seems like there's no easy way to do this, lol

[floral dove]

no, you're trying to do a complex thing 😛

[normal yarrow]

True, lol

[normal yarrow]

I should mention the videos are pretty short, usually a couple of seconds long on loop

At least for everything but the main tron graphic, which is usually a good bit longer.

[floral dove]

You could combine them all into one video and loop the shorter ones long enough to match your longest loop, then map them all to the different surfaces

then you only need to load and play one video

[normal yarrow]

I can try that

[serene shale]

ETA on dynamic loading of externally hosted images?

[dim horizon]

That's what I did for the TVs in my Asylum map. It worked out pretty well. Here's the base video that I used. https://youtu.be/FAW0dkscA7I

And here's the result

https://youtu.be/MyKp568qSU8

I just basically have a camera pointed at the YouTube player screen and then mapped out the UVs for each TV to show a different section of the screen.

[fading cipher]

Is it a known bug that Input events don't run when the user has their VRC quick menu open?

[dapper lion]

i thought that was normal?

[pallid mango]

Doesn’t it block your inputs anyway? If you move it will close

[fading cipher]

I mean if you release your grip, InputGrab doesn't run

That's pretty dang important if you're programming things to happen based off that and simply opening your quick menu completely circumvents it huh

I'd 100% call that a bug even

[pallid mango]

Yeah that sounds like a bug. At the very least opening a menu should release the grip

Report it on canny?

[fading cipher]

Will do 👌

[stray junco]

how to disable (close) UdonGraph welcome screen
so i can work with my UdonGraph normally

any suggestion?

[cold raft]

yes goto an udongrapth behavior in the inspector and click open graph

[dapper lion]

are teleports currently teleporting to spawn on the 2019 unity version? been having issues and the scripts work on 2018 but not in OB

[floral dove]

It's not a bug, no inputs are allowed to be processed while the menus are open, for security.

[floral dove]

Teleport is working for me in OB, yes

[dapper lion]

how does graph look? maybe somethings changed and im not seeing it

i totally did not just close the project that had the teleport script in it

[fading cipher]

:( okay

[stray junco]

@cold raft
where exactly i can find open UdonGraph?

[floral dove]

You need to create an Udon Graph Program before you can open it, or choose an UdonBehaviour that already has a program on it. If you're just getting started, I recommend you check out these pages:
https://docs.vrchat.com/docs/using-build-test
https://docs.vrchat.com/docs/udon-node-graph
https://docs.vrchat.com/docs/udon-example-scene

[cold raft]

yes click on that new program button

[stray junco]

@floral dove
oh so i need to open UdonGraph tab first
and then to open in inspector
ok got it
ty 👍

[floral dove]

if you don't have an UdonGraph tab open, clicking 'Open Udon Graph' will create/open the tab for you. The issue is you first need to create a graph to open.

[stray junco]

@floral dove
ah what can i say...
i was so stupid
because i didn't see on right side the name of the button
because i didn't expanded inspector menu to the left side
sorry for all this nonsense i cause 😒

[floral dove]

Np- we're all at different stages of our learning

[storm sable]

Has someone already conducted a test, on how heavy SendCustomEventDelayed() is? I want a event to be fired every <1s, based on if a flag is set. Is it better to use Update(), checking a time variable, or queuing the event every time with SendCustomEventDelayed()?

[grand temple]

it's definitely faster to use the delayed event because that runs outside of udon

[storm sable]

Perfect, thanks!

[supple flicker]

It says I'm not using the right unity version for the sdk even though I'm using version 2019.4.28 for both unity and the sdk. It says I need to use unity ver 2018.4.20.

[floral dove]

yes - that's listed as a known issue - that will go away when we release 2019 as the main version. Also, windows-shift-s will let you easily take a screenshot of your desktop 😉

[supple flicker]

K thx

Also, whenever I try to build and test it takes me to my home world.

[dapper lion]

sounds like vrworld tool kit time or check console or just. dont do build and test. or you might be using the wrong vrchat all together

[solemn talon]

Does the OnPlayerLeft event fire before or after the player leaves?

And would the leaving player still own objects when the event is triggered?

[supple flicker]

What's vrworld toolkit time?

[floral dove]

did you follow all the instructions here? Make especially sure your VRChat path is set up in your settings.
https://docs.vrchat.com/docs/using-build-test

if all that is correct, you likely have errors when you build - check your console.

[pallid mango]

It’s triggered when your client realizes someone has left. Which might be in a completely different orders of events for other people.

Ie: when you join, you also get a join event for every other player already in the room.

[daring vector]

Looking for some help on how to trigger the "trigger" parameter. I see a lot of methods online using bool but I'm looking for an interact to simply trigger my parameter.

[grand temple]

animator set trigger

[daring vector]

/sigh. I knew it was something super easy

gonna test it out now 🙂

@grand temple

[indigo finch]

Trying to keep a VRCPlayerApi array updated as people leave and enter a world, but it doesn't seem to update after it's called the first time. Any idea what i'm missing?

[grand temple]

the script is probably crashing

doing an equality check on a playerapi that has left will still return true. You need to instead use utilities.isvalid for such a situation

however, for that specific use case you don't even need to do anything like that yourself. Just run playerapi.getplayers once onplayerjoin and it will automatically populate the array

then you don't need to remove them from the array because every time you try to access it, just use utilities.isvalid and that will exclude players that have left

[indigo finch]

Thanks for the help!
This was a little bit of a test run, but the real use case will have only a portion of the players in the array at a time, and I want to grab and remove them at will

[grand temple]

I would recommend having one big array of all the players and then a secondary array where you separate them out individually. This is because the getplayers function is relatively expensive as it doesn't just access an array, it fill the array up. So you shouldn't just casually use it every time you want to access all the players, especially inside a for loop

[indigo finch]

Would make a lot of sense, Thanks for the tip 🙂

I just edited it as i had tried previously, but this causes it to crash on the second int of the for loop

oh, and here is the other bit just to be sure

[grand temple]

it's a bit confusing, but you don't want to use playerapi.isvalid. You need utilities.isvalid

playerapi.isvalid is accessing a property on the playerapi, so if it's null as is the case of an unfilled array, then it will crash. It will only work if it's a playerapi that you knew used to be valid but isn't any longer because they left

[indigo finch]

hmmm... would i also want to use utilities.isvalid if I was checking to see if say a gameobject array was missing a spot too?

[grand temple]

No, that's not necessary

However utilities.isvalid is slightly more convenient in graphs since it combines 3 nodes into one. So you may still use it for that reason

[indigo finch]

Ah, okay.

Just checked it, but it doesn't seem to be updating with the new instances. any more ideas?

using cyanemu, errors do pop up...

[grand temple]

Don't run getplayers in the for loop. Just run it onplayerjoined

[indigo finch]

ummm... how would that look in the graph? should i make a variable for the 'get players' to store it in?

[grand temple]

Yeah, exactly

[indigo finch]

unfortunatly, still getting the errors. did i miss something?

[grand temple]

Click on the errors to see what they are

[indigo finch]

all gibberish to me...

[grand temple]

The important part is that it's trying to access a gameobject array and the object reference was not set to an instance of an object

Make sure that your gameobject array has exactly the same number of objects as max players and all the objects are valid

[indigo finch]

They are the same, even tried making the max lower to no avail

perhaps it has something to do with one of the earlier error messages

[grand temple]

Add a debug log of the current value of intty and then the length of the gameobject array

[indigo finch]

It seems like the graph is been called multiple times...

[grand temple]

Yes, every time a player joins

[indigo finch]

4 times though?

[grand temple]

It's inside a for loop

It only runs twice

The second is when it goes back to 0

Something appears to be clearing the gameobject array. Do you have any other code anywhere else?

[indigo finch]

that it! each of the cubes had the same script on them... ouch

[indigo finch]

Got it! script works! Thanks for all the help! Wouldn't have figured out half of that 🙂

[pure parrot]

does anyone know a way to learn quickly the basics and some more advanced stuffs ? the tutorials on yt are good but i don't understand 30% of it and I would like to do some stuffs that are pretty hard to do in the future , like assign a trigger box to the Back chest of all players

[floral dove]

I recommend you read the docs in the following order (assuming no knowledge at all):

• https://docs.vrchat.com/docs/getting-started-with-udon
• https://docs.vrchat.com/docs/using-build-test
• https://docs.vrchat.com/docs/udon-node-graph
• https://docs.vrchat.com/docs/searching-for-nodes
• https://docs.vrchat.com/docs/udon-networking
• https://docs.vrchat.com/docs/debugging-udon-projects

Then go through the UdonExampleScene and docs to understand common approaches and patterns: https://docs.vrchat.com/docs/udon-example-scene

[neon rain]

Is there anything like OnPlayerParticleCollision that checks if a Particle has collided with a GameObject?

[grand temple]

yes, there is. It's named exactly that

oh wait, you're saying you want something that has similar functionality to OnPlayerParticleCollision, but not for players?

If so, then it's just OnParticleCollision

unlike OnPlayerParticleCollision, you can put that one on both a particle system or a collider. If you put it on a collider, it will give you a reference to whatever particle system hits it

[neon rain]

I've been looking through the docs and I can't find this

[grand temple]

depends what docs you're looking through. This is not a vrchat function, it is a unity function that vrchat exposes. You can read more about it here https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnParticleCollision.html

[neon rain]

Figured it out, thank you!

[rain marten]

Im having a slight meltdown in the brain thinking department:

Is there a way to make a set percent chance that goes up over time?

Example: A 1/10 chance for a function to occurs fails, and thus becomes a 1/9 chance

[neon rain]

Okay, I have a script that is supposed to play a sound effect on particle collision. I think I have something wrong in the actual playback part, because when I use CyanEmu to force the collision event, nothing happens. Here is my script and setup:

[floral dove]

sure - make an int variable that you use in a Random.Range(min,max) call. Subtract one from the int every time you call it (until it hits 0).

[gusty trout]

Hey, I've been working on a world that has AudioLink set up, but now I'm trying to add a canvas slider that changes the intensity of emissions in the world.

Judging by what came with AudioLink, seems like I'm going to need some Udon# scripts/noodles to handle the behavior.
I'm also hoping to have networking set up on this too, so it is server-side instead of only client-side.

I'm pretty new to Udon so if anyone knows of any tutorials or assets that can point me in the right direction, I'd really appreciate it.

[rain marten]

Fantastic, Newer question though: is there a way to compare the numbers to check if a number was infact hit? (1/10 chance, it hits the 1/10 and activates a separate function)

Im basically asking for a budget "IfElse" lol.

[scarlet lake]

so it does work

[rain marten]

Also, ignore me, i found what i was looking for

[floral dove]

Did you do int > 0 and Branch?

[rain marten]

yep yep

[daring vector]

Question: is there an elegant way in Udon to spawn an object that only the spawned can pickup? In the past SDK2, I would have a prefab without a pickup enabled, on spawn I change the prefab local to enable pickup then spawn, then change prefab to no pickup again. This would work but hoping there’s a more elegant stable method now.

[floral dove]

spawned objects are local-only, so if that works for you, you can just use VRCInstantiate

[daring vector]

Spawned objects are local only? I mean if I object sync them they won’t be, right?

I need the world to see the spawned object but only the spawning player to be able to pick it up

[grand temple]

in that case, you'll need to use a vrcobjectpool. It will behave similar to instantiate, but instead of creating new objects it will enable them from a set of objects that already exist

once you have that set up, locking down who can pick it up is as easy as just enabling pickupable for the person that clicked spawn

[daring vector]

But would that enable any future people that click spawn able to pick up all spawned objects?

Or will each be unique to the person who spawned it?

[grand temple]

depends entirely on how you set it up. But probably not

when you call trytospawn on the objectpool, it gives you a reference to that gameobject. Then you just do getcomponent vrcpickup, pickup set pickupable

the one edge case you'd want to handle is if someone spawns an object, then despawns, then somebody else spawns it again. So you'd need to make sure the objects disable pickupable from the ondisable event

[daring vector]

Okay I’m brand new to Udon so I’ll try to figure it out. There’s like 2 spawn tutorials on YouTube and both seem overly complicated for what needs to get done

[grand temple]

ok, here's what you do for a basic pool:

add a vrcobjectpool to an empty gameobject

duplicate a prop a bunch of times

put all the props in the pool's list (you can do this all at once if you lock the inspector at the top right)

make an udonbehaviour and put it on some button object

add a public VRCObjectPool variable to that udonbehaviour

add an interact event, make it trigger networking.setowner with the networking.localplayer

then make it call vrcobjectpool.trytospawn and use the public pool variable that you added before

on the udonbehaviour, plug the pool into the public variable slot in the inspector

[daring vector]

I’ll give that a try tonight, thanks. Question, is a pool limited to the number of pool items I create? I assume so

[grand temple]

yes it is

[daring vector]

K

So none of that will make it pickup able to just the spawned though it seems, right?

[grand temple]

nah, start with getting a pool to work then you can add that

[daring vector]

Kk

Thanks again. I don't see how a pool will benefit over just instancing an object, but I'll trust you

[grand temple]

it's not entirely about benefits, it's just that SDK3 does not support synced instantiation

there is some minor advantages to memory usage, it's much more efficient. But if it was possible I would still suggest instantiating for a beginner because pools are more complicated and more limited.

[rain marten]

So, bluntly, ive been at this for about three hours now resisting the urge to ask here:

How to i make a "start game" button. As in: I click a cube, the cube vanishes, and it starts either A: a global function of some kind that allows me to play an animation on a totally separate object, or B: Just plays the animation directly to the separate objects.

Im entirely new to UDON and to be honest worldmaking as a whole so do bare with my potential not-smarts.

[grand temple]

you would need to have a reference to the animator and then all you have to do is call animator set trigger. Then the animator can have a trigger with the same name that is used as a condition in a transition to an animation

[daring vector]

@grand temple should my pool be inactive when I build?

[grand temple]

the pool itself should be active. The objects I think would get disabled by the pool so that probably doesn't matter

[daring vector]

k, testing now

k, that works

that was very clean and easy to follow/understand so far

[grand temple]

do you want to do trashcans or something?

[daring vector]

So what is happening when it's SetOwner to me?

[grand temple]

only the owner can spawn objects from a pool

[daring vector]

it's just making me owner but anyone that picks it up becomes owner anywa, right?

picks up the spawned pickup I mean

[grand temple]

you're setting the owner of the pool, not the object

[daring vector]

oh

[grand temple]

the object's owner will be determined by whoever picks it up, so no need to set it manually

[daring vector]

right.

so now with this, I need to find a way to make the spawned pool object to only be pickupable by the person who spawned it

[grand temple]

when you run trytospawn, it gives you a gameobject. So first thing is to check if that is valid with the utilities.isvalid node. Since this is a limited pool, it's possible that the pool is already completely taken. If that's the case, it will give you a null object and isvalid will catch that

if isvalid gives you true, you can continue on and run getcomponent on that object with the vrcpickup type

once you have the vrcpickup, all you do is set pickupable to true

[daring vector]

to local player only, right?

or is it already only affecting local player

[grand temple]

yes, all code in udon is local by default. It will only affect other players if you explicitly tell it to, like by sending a network event or setting a synced variable (which is what the pool is doing behind the scenes)

unless of course there's an event like onplayertriggerenter, which everyone sees. Then the code inside that would run for everyone, but not because it's inherently synced just because they're all experiencing the same thing

interact however is a local event, so this is all you

[daring vector]

okay so my objects in the pool dont need their own objectSync added to them or anything as long as it's in the pool

[grand temple]

no, the pool handles enabling/disabling but the objects inside still need to do their own position syncing so you would need objectsync for that

[daring vector]

oh okay

K, I'm a bit lost on the Is Valid. I have that in on my TryToSpawn. Then from True you said I can getcomponent on that object. but how will I know which of the pool objects it is?

[grand temple]

you can pull it out multiple times and reuse it

[rain marten]

While im here i guess, Would this system work? It doesnt do anything in particular at the moment but is supposed to replicate Russian roulette more or less.

1/6 chance, if the 1/6 fails it shortens down to 1/5 chance and so on. If it passes, resets to 1/6.

[grand temple]

I don't think compareto is doing what you think it does, especially to a bool

what do you want it to do?

[rain marten]

Ok. lets go step by step.

RevolverChances_1 is set to a value of 6.
Range will pick a number between 1 and RevolverChances (I'll call it RC for now)
That number gets checked to see if its greater than 1. This gets compared to the yes or no values.
If yes, it would output a 1 (correct me if im wrong), which i can send to the subtraction to lower the Number for RC (Thus making it a 1/5 rather than 1/6)
If No, The output would be a 0 (Again, correct me if im wrong).

This is where things get messy cause im not exactly the smartest. If it passes the "No, its not greater than 1" test, then it resets the value of RC back to 6. (Reset_1's value is set to 6 as well, cause again, not smart.)

[grand temple]

ok I guess compareto is doing what you expect but that is a little weird to do it in that way

[daring vector]

I'm still stuck on the Is Valid - but I'll mess with it some more to figure out - thanks again for the help

[rain marten]

True but i dont exactly know of a better way. Glad that means it technically works for what i want it to do then

[grand temple]

I'd recommend instead plugging the bool that you get from the the greaterthan into a branch. That will split up the flow so you can do two completely different things depending on what the outcome is

[rain marten]

I'll be totally honest i wasnt even aware that was a tool lol.

I'll rewrite it tomorrow since its currently 4 am and as much as i do have an idea of how to make it probably better with the branch function i really cant be bothered rn lol

Rewriting it also gives me a chance to add another function in RR, which is to spin the cylinder, which technically resets the chances to 1/6

[fading cipher]

lol programming until 4am, you're doing it right

[tulip sage]

How do you join a public server?

[midnight beacon]

You mean a world in VRChat that's public?

[tulip sage]

Yes

[fading cipher]

Hey y'all, tad bit confused. I have a bunch of local only object with 0 networking stuff happening in them and I'm scrolling through my logs to find a massive amount of ownership transfer logs regarding them

https://i.imgur.com/tm16uZE.png

Does network ownership get applied to everything on scene load up even if the object itself isn't actually networked?

[midnight beacon]

Sorry for not responding, got sidetracked /o/

At the bottom of a world page itll show you the public instances of it, if there are any. Just select one.

[floral dove]

Yes - every object with an UdonBehaviour is assigned a Network ID even if it doesn't have synced variables

[fading cipher]

oof okay

[midnight beacon]

Am i doing something wrong with this script that attempts to destroy GameObjects that enter a trigger? The log activates but the object remains intact. Tried searching for answers and I couldn't find anything 🤔 .

[cold raft]

if you can re-use them you might want to return them to a pool instead

[midnight beacon]

I'm just starting out and id like to get to that, but it would be good to know why something simple like this doesn't work :S

(nvm worked it out, turns out there's two types of destroy and only one will apply locally? shrug)

[broken bear]

how do I export a udon graph to a string that others can copy-paste into their graph to import?

[dapper lion]

wdym?

like the .asset?

or like specific nodes

[broken bear]

sometimes when I ask for help here some people have linked a string that I can import and it loads the graph on my side

[slim hound]

You just select the nodes want to copy and either control c or right click > copy

[broken bear]

good stuff, thanks

[main river]

Hey everyone, Im brand new to making VRchat levels, but have experience in game dev when it comes to environments and modeling. I was trying to block out my level, and was wondering how to get characters to sit cross-legged on a floor pillow vs the standard sitting position. I replaced the mesh on the Udon chair prefab to the one I wanted, just not sure how to change how the character sits when it interacts with the prefab

Sorry if this is the wrong channel, if it is, Ill post it in the correct one once I know which one that is

[dapper lion]

i might be wrong but i believe theres a "enterance" animation on the vrc station scrip where you can add a criss cross animation on

[main river]

I don't see anything about an animation..

[dapper lion]

not the graph. the vrc_station

[main river]

oops. My bad.

[rain marten]

I rewrote my code from last night and somehow i think i made it messier. Can someone confirm for me that this would infact do as i wish it to do?
(Check for a 1/6 chance, then if it fails lower the chance to 1/5 and so on. Resets to 1/6 when passed.)

[main river]

I do see a slot for an animation controller which is currently blank. Is it safe to assume Ill need to create a controller, add a new sitting animation to it, and then plug it into the VRC Station's animation controller?

[rain marten]

That would make sense. Im fairly certain theres already a VRC controller for seats somewhere in the VRCSDK examples

[main river]

There are, but it looks like just two different poses for default sitting positions. Ill take a look through the rest of the animations, if there is one, Ill duplicate an existing controller and add that animation to it, or make a new animation. Thanks for the help you two!

[rain marten]

You can overwrite the sitting positions directly with your own sitting animation. I'd recommend duplicating the controller anyway either way lol.

[main river]

haha yea. Wouldnt want to screw up the originals 😅

So to create this new animation I should probably download the avatar SDK, correct?

Just so I have the same character rig as the rest

[rain marten]

Not sure on that one

You should probably just need world SDK

since the rigs are the same either way more or less

[main river]

So I tossed the new animation controller containing the cross leg animation pose in the Animation Controller slot in the VRC Station script of the chair, but every time I build to test, it keeps detaching it from the script 🤔

[topaz jetty]

I started my vrchat in debugging mode by adding --enable-debug-gui in the launch options and need to copy some numbers my world puts out in the console, is there any way I can select it to copy it?

[fiery yoke]

You cant. At least not in the console. You can try to find that line in the Log which is located at...

[dapper lion]

anything written in there will be in your debugs log

[fiery yoke]

Do you remember the command for the logs lol?

[topaz jetty]

--enable-debug-gui...?

idk

[dapper lion]

im pretty sure its written in there by default. weather thats on or not

[topaz jetty]

I tried searching for the word log in the vrchat game folder with no results...

[dapper lion]

in appdata?

[topaz jetty]

no in the steam program files

is it in appdata?

[dapper lion]

should be

[fiery yoke]

its in %userprofile%\AppData\LocalLow\VRChat\vrchat

[topaz jetty]

yeah I found it but there's only logs from yesterday there for some reason

not from my current session

is it because of the debugging mode?

nvm found it, thanks

[glossy sky]

Hi hi. I was wondering if anyone else is having issues with GetPlayerTag? Works with CyanEmu and in Unity but doesn't work when actually in VRChat. Thank you in advance!

[daring vector]

K, round 2 of trying to figure this out: So I need help with setting my SpawnedSphere to pickupable. Not sure if I have this structured right but it's not working.

"pickupable" is unchecked on the spawned item by default. So trying to turn that on when it spawns it

[cold raft]

Well first thing I spot, you got to tie the gameobject from try to spawn to is valid, and you should probably check isvalid before setting ownership

And your variable spawned sphere is not getting set, you should connect the same gameobject from try to spawn also to the get component

Than it should work

[daring vector]

that object from TryToSpawn is a pool though, there's no pickup component in the pool itself, only the pool children

[cold raft]

Try To Spawn is done on an instance of VRCObject pool, the value that gets out of it is a single object from the pool

So I assume that is you sphere

[daring vector]

yeah

[cold raft]

Do that sphere does it have a pickup on it?

[daring vector]

It has a pickup script, but "pickupable" is unckecked. If I have it checked, it spawns it and I can pick it up just fine

but I want it unchecked by default and only enable the pickup for the person who spawned it form the pool

[cold raft]

Ah I see..

🤔

Well that's correct than right? There is no networking involved here so it all runs locally

I am not 100% if pickups synch there pickupable state I would assume not

[daring vector]

not sure if its synced but either way it's not activating it

[cold raft]

Can you show what you made of it

[daring vector]

oh, I kind of reverted back to where I was to start so no real change

I did notice there are two VRCPickup Types though...

VRC_Pickup Type and VRCPickup Type

I tried both and no results

I really just think my IsValid is not firing properly

I did try one other thing that I was sure was gonna work...

I dragged the Pickup component straight from inspector into the graph

and it made that new node

but it still didnt work

I just did one other test where I made a separate button with just those two nodes which should enable the pickupable to that object and that's not working either. So now I'm wondering if that Set Pickupable is working as it should be...

[slim hound]

You are doing an Is Valid check against nothing?

It will always return false

[daring vector]

I thought that was checking if there's still pool items (I'm new to Udon)

[slim hound]

The VRChat object pool handles that

Don't need to do it yourself

[daring vector]

okay, so I can go from TryToSpawn to Set Pickupable?

[slim hound]

Yes

[daring vector]

awesome

okay, so my next test to simplify things is to see if Set pickupable is working and my smaller test is telling me it's not

this is my test:

I have a capsule with a pickup script. I unchecked pickupable.

I made a new button that on interact, set pickupable on that capsule pickup

and that's not enabling it

I know there's been funky things with "pickupable" in SDK2, not sure if it's still not a reliable checkbox or if I'm just not using it properly

[daring vector]

That looks right though, right?

[slim hound]

Sure

But if you have that on a pickupable object it might override the interact event

[daring vector]

no, that's just a separate button that should enable the pickupable of the capsule

nothing fancy about it. but it's not working

[grand temple]

@daring vector @slim hound you absolutely need isvalid because if the pool is all taken up it will give you null. Also, you have a whole bunch of stuff disconnected and not coming from anywhere.

First of all, the flow is all wrong. The white line specifies the order that things happen so you need to have it setowner first, then do trytospawn. You would do this by plugging the flow from the right side of setowner into the left side of trytospawn.

You want to plug in the pool's gameobject into the setowner, not the thing you get from trytospawn. This is because in order to spawn, you need to be the owner of the pool. The object you get from trying to spawn does not matter.

You never set spawnedsphere anywhere so trying to get it is just going to crash your script

You can drag out a variable multiple times, so you want the gameobject coming from trytospawn to go into both the isvalid and the getcomponent

You have to plug the getcomponent into the set pickupable. VRCPickup is the type you want.

[daring vector]

Reading and working through this - one sec.

I know this isn't right because it's not working, but this is what I understood...

[grand temple]

you still need to plug the gameobject from trytospawn into getcomponent

you can use it multiple times

[daring vector]

It wouldnt let me

TryToSpawn GameObject to the instance slot of GetComponent, right?

[grand temple]

get rid of the spawnedsphere first

[daring vector]

ah

Okay, awesome, I can pick them up now!

[grand temple]

woo!

[daring vector]

now let me go back and re-read this and ask questions if I dont understand the flow

[grand temple]

that's pretty much everything for this section

now you need to add an udonbehaviour on the objects that will handle despawning them and setting them back to pickupable false

do you want to have like trash cans or something?

[daring vector]

no, I don't want this object to be despawned ever

[grand temple]

what about when the person that spawned it leaves?

[daring vector]

yeah, that would be a good reason

[grand temple]

also, do you want to restrict it so you can only spawn one object?

[daring vector]

no, so let me clarify the use case of this

This is to spawn a reward for the user. They spawn it when they complete a challenge (probably not more than 5 people will do this per session so wont be too many)

only the person that completes it can pick it up

show it off, so on

nobody else can touch it but everyone can see it

[grand temple]

oh, that makes sense

then yeah I guess that's pretty much it

though if the instance goes long enough, you'll run out of trophies

[daring vector]

but would be nice if it gets trashed when they leave... or not, that's not as important

yeah, I mean, I was thinking of having like 10 in the pool

[grand temple]

yeah, all you have to do is add an udonbehaviour on all the objects that does

onownershiptransferred > set a variable called "lastKnownOwner"

onplayerleft > if the player given is the last known owner and I am the owner of the pool, return to pool

[daring vector]

lastKnownOwner is the pool?

[grand temple]

nah, just a playerapi variable that you make

[daring vector]

so how would that OnPlayerLeft be structured to do that?

[grand temple]

onplayerleft gives you a playerapi, you have a playerapi variable. Plug those into a system.object equality node. Then plug the result of that into a branch node. Branch will allow you to make stuff happen only if the bool that you get from the equality is true

this also needs a reference to the pool so make a public vrcobjectpool variable. You can plug that into a vrcobjectpool return node. And then you can just leave the obj slot of return empty because that will just reference itself automatically

[daring vector]

I'm not clear on what the equality is doing

[grand temple]

it's checking if two objects are the same thing

if they are, it will give you true

[daring vector]

ah okay

So is this what I'm testing? Seeing if the player that left is = to the last known owner?

[grand temple]

yep, now just plug the flow together from the onplayerleft to the branch. Currently it would do nothing because there is no flow

[grand temple]

oh, the return is not correct. You need to plug the pool into the "instance" slot, that's referring to the pool itself

the obj slot is referring to the object you want to return

and currently the pool is a gameobject variable so that won't slot into there, you need to change it to a vrcobjectpool variable

[daring vector]

k, you lost me there

[grand temple]

you have a gameobject variable for the pool, change it to a vrcobjectpool variable

then slot that into the "instance" of the return node

and leave "obj" blank

[daring vector]

I got that, but not sure how to change that, let me see

[grand temple]

just delete the old pool variable and make a new one

[daring vector]

I'm confused on how it's still referencing the pool at this point though

[grand temple]

the pool variable needs to be public, which will make it show up in the inspector. so when you put this udonbehaviour on an object you'll need to plug the pool into it

[daring vector]

got it, that makes sense. And I'm sure that's going to be one of the things I'm going to forget to do in the future 😄

[rain marten]

The use text on a VRC PickUp: any good way to change that via the player using the item?

[daring vector]

I really appreciate this 100%!! means a lot to me, honestly. Let me take a moment to take this all in and review this

[grand temple]

sure, you can just set that with the VRCPickup Set UseText node

[rain marten]

fantastic

[daring vector]

So it's all working except for the onPlayerLeft. I tested with 2 players and when the player left, the object didnt return. I think it might be my OnOwnership Transferred

I just have it as a string variable and that doesnt seem right

[grand temple]

yeah, you're not doing anything with the player that has left

and lastKnownOwner needs to be a playerapi

[daring vector]

got it

This should do it

[grand temple]

it's still a string

[grand temple]

yeah that should do it

[daring vector]

so before I test this, this brings up a question. Now that the item is returned to the pool when the user leaves, will it not continue to have the lastKnownOwner tag?

[grand temple]

it will, but it will be disable so it doesn't matter

[daring vector]

will that affect things if it becomes spawned again by a new user later?

[grand temple]

no, because you'll only ever receive one OnPlayerLeft per player

[daring vector]

Okay, still not working and I'm getting an udon error now

Specified cast is not valid

[grand temple]

does it give any information?

maybe vrcplayerapi isn't a system.object hmm

[grand temple]

yeah that's definitely referring to plugging the playerapi into system.object equality

try unityengine.object equality instead

[daring vector]

that doesnt seem to let me snap the VRCPlayerApi into it

Is it that though? I removed it and compiled and the error is still there

[grand temple]

hm, that's odd. There is no playerapi equality, so you could try playerapi equals, but there's a difference between equals and equality and I'm a bit fuzzy on which one is needed here

[slim hound]

That's an error with adding variables in Udon Graph

You need to restart the editor to fix it

[daring vector]

restart and no error

You guys are Gods.

So I tested and still not going away. Could it be a local test issue?

because I'm using 2 local players?

[slim hound]

Do you ever manually transfer ownership of the objects in your pool?

[daring vector]

no, only the person who spawned it can pick it up so there's no ownsership transfer

[grand temple]

did you pick it up before leaving?

[daring vector]

oh wait

one sec

[grand temple]

yeah, since we're doing it this way you'll want to setowner of the object the pool gives you too

[daring vector]

my other objects in the pool don't have the public pool variable even through I told the prefab to override all

[grand temple]

prefabs can only maintain references internally. If it's to a reference outside the prefab, that won't be saved

but even then, prefabs and udon don't get along very well

[slim hound]

If no other player can ever take ownership other than the person who spawned it you could just use OnOwnerShipTransferred to send it back to the pool

With a behavior on the pooled object itself

[daring vector]

@slim hound that sounds right to me...

(this one still isnt working)

[grand temple]

are you getting any udonbehaviour errors?

[daring vector]

gah, one sec

[grand temple]

huh, I've never had that before

[grand temple]

oh, something went wrong when you switched the pool from a string to a vrcobjectpool

it's probably remembering something old that no longer exists. Try renaming it to something different

[slim hound]

If the error hasn't changed that probably isn't possible

The invalid cast error makes udon graph completely unusable

[grand temple]

do you know how to reproduce it reliably? I can't get it to happen by just naming a new variable the same as an old deleted variable

[slim hound]

I only ever got the error when adding variables by dragging and dropping them into the graph

I know it never occurred if I had just opened the udon graph program directly

[daring vector]

No more error when I made the pool a new name, but still not working. I'm going to try having it just return it on ownershiptransfer

I think that's an elegant solution and makes sense

[grand temple]

you'll have to add a timer that makes it not return if it's been less than a second since being spawned

you can do that by just setting a float onenable

and use time.timesincelevelload

[slim hound]

Shouldn't need to do that if you check if ownership is going to the master and only returning if so

Also the reason it wouldn't be working is you are storing last known owner as the new owner

[daring vector]

yeah, it's being returned the second I touch it for the first time lol

because it's changing ownership to me

[slim hound]

Try do OnOwnershipTransferred then check if it was transferred to the master and if so then return

[daring vector]

can I use a branch to do that?

remember, I'm new to all of this

[slim hound]

Yeah but from the Ownership Transferred event plug the VRCPlayerApi into the Get isMaster

[daring vector]

makes sense

Again, GODS!

works

@grand temple @slim hound Thank you so much

I appreciate the guidance and it all makes sense and is easy to follow. Learning more of this as I go.

[tranquil summit]

Any idea why this graph isn't setting the boolean back to false once it hits 10 seconds?

i have a proper timer that does work in the behavior, that's how it enters this condition, but for some reason it'll make the boolean true, but never set it back to false

[grand temple]

Everything going along the flow like that happens instantly

[tranquil summit]

thats why i have the greater than condition- oh wait i see

[grand temple]

I see you have ondeserialization and onplayerjoined but it's really hard to tell how those are connected when everything is squashed together like thet

[tranquil summit]

yeah im gonna be removing one once i get to testing in game, but now i see why it isn't working lmao, i just need to put my false statement in a better location

[grand temple]

you could just use a sendcustomeventdelayed

[tranquil summit]

u rite

[rain marten]

I think i refined my code from yesterday. It now uses a branch and custom events to tell things when to fire off in order.

What im having issues with now is setting custom events for a few specific things

[daring vector]

I’m away from my desk now but just had a thought. Do pool spawned items have a pre set action when they fall off the world? Or do I have to set that?

[grand temple]

the pool doesn't care, but if you have objectsync on them then they will be respawned

you can change this in the scene descriptor

[rain marten]

1: Im trying to make it so that its a single action revolver: You have to pull the hammer back (Use1), and then pull the trigger.
2: I also need to make it so that it will fire a bullet if it hits the "false" on the GreaterThan Check (preferably just play the animation thats set on a bool value currently)

[daring vector]

Respawn being where it spawned from or respawn back into the pool?

[grand temple]

it's original position

[daring vector]

K perfect

[rain marten]

Currently, the absolute nightmare of code i have right now is this:

[grand temple]

if this is on a pickup, just use pickupusedown. InputUse will trigger whether or not you're holding it. It will also trigger for both hands and for both down and up

[rain marten]

Got it.

and any ideas on how to make it single action? (Pull hammer on one use, pull trigger on second, resets to the start)

[grand temple]

keep track of the state and have branches based on what state it's in

[rain marten]

Got it. lemme think of a way through that quickly.

[indigo finch]

I feel like I'm missing something basic, but any idea why this is throwing out errors?

[grand temple]

For all the udonbehaviour methods like onplayerjoined, you need to do 'private override void OnPlayerJoined'

[daring vector]

Weird "W" appearing on my "Sit" text. I'm not concerned for now, just wondering why this is happening,

[indigo finch]

yup.. something basic. perhaps. Unfortunately, it didn't like me adding the override... anything else i've missed?

is it just meant to be public?

[grand temple]

Eh maybe I got the order wrong. Delete those entirely and starting typing 'override onplayer...' and your autocomplete should make it correct
