All I did was take the default sitting controller, duplicate it, and then replace the sitting animation with my own

#

my sitting animation has the exact same settings as the normal sitting anim

#

I'm trying write defaults now, give it a moment

#

write default doesn't do anything either

manic yarrow
#

Also, doesn't seem like it's my animation's fault

#

I used the AFK animation just to test and got the same thing

formal leaf
#

what's the difference between Event InputUse and Event Interact? i can't seem to find any info on these things...?

cold raft
#

Interact is used for creating clickable objects like a cube with a behaviour on it with an interact event handler that gets triggered when its clicked

#

I never used inputUse but afaik it has todo with actually controller inputs

formal leaf
#

im using an udon program to settrigger on an animation controller to play an animation, but the animation doesn't play, it shows on the anim controller preview the state machine working, but the animation doesn't play

hi

i don't have any programming skill's
and i wonder what word "Variable" in VRC-UDON term means ?

floral dove
manic yarrow
#

@pallid mango I just decided to rebuild my entire project using the new SDK in case that helps, but it didn't seem to do anything for these chairs

#

I noticed that even if I use the default animation override, the 2.0 standing bug still happens

#

WAIT

#

fixed it

#

I just replaced every single animation in the controller with the sitting animation

#

and somehow that works

#

never mind, you can't get out of seats

feral valve
#

Is it possible to make a collider not allow portal placements?

edgy ingot
#

how performance heavy is Update() if im just checking a couple int comparisons?

fathom parrot
#

so I am trying to update UI dropdowns at runtime with udon# Being that Lists are not supported. what is the magic way to do this?

lyric mason
#

Probably would need to create an array of X size. Just a guess; new to Udon myself.

stark adder
edgy ingot
#

just this
doesnt seem to cause any problems

Has anyone got any ideas why I might be getting a NullReferenceException when I call the PlayOneShot function, but only when called after the rest of the functions? If I just start an event and call the PlayOneShot function it works fine. The Debug.Log immediately before the audio is being triggered.

unknown.png
solemn talon
#

I think I've managed to narrow it down to the GetComponent actually

#

Well I've fixed it by adding this right at the start of my program and access the AudioSource by a variable

frank lily
#

this latest issue has made the problem SIGNIFICANTLY more obvious

#

my world has become unusable after todays update

#

the room master even on desktop only has about 10 fps while everyone else keeps a solid 45fps. in vr i only had about 5-6 fps

#

it was not like this until todays update and i have no idea what to do

cold raft
#

if it really only affects the master, i assume the master is owning a lot of udon scripts

#

maybe some code its requesting the master to be the owner of most things

#

i think you can see who owns which udon behaviour by one of the new debug options

hallow steppe
#

how do you tell whats taking up the most mb?

cold raft
#

what do you mean by most mb? i assume you mean the filesize of your world? in that case its not a udon question

hallow steppe
#

well i just see someone talking here so i figure id put it here the rest are kinda dead however my world is running on udon so that could be part of it

unknown.png
cold raft
#

well in #world-development in the pinned messages you can find VRWorldToolkit it adds a lot of options one of them is showing how much mb is used by what parts of your world

frank lily
#

maybe updating my sdk would fix this?

slim hound
#

Or post the world ID and I'll just take a quick look myself

frank lily
#

yeah im uploading s version without the video player atm

#

youd need multiple people in the world i think

#

@slim hound

#

ill update it in like 5 minutes

#

you can check it out if you'd like

slim hound
#

Yeah it isn't the video player

unknown.png
frank lily
#

wtfffff

#

how did that happen lol i didnt change anything xD

grand temple
#

looks like you're syncing a gameobject variable

slim hound
#

Do you have an array targeting these gameobjects or something?

grand temple
#

you can't sync references to objects

frank lily
#

ive no clue where that might have happened

#

hhmmmmm

#

how do you mean an array super?

slim hound
#

Don't worry about that

frank lily
#

oki those objects all have buttons on them

#

for toggling stuffs

#

heres one of yhe buttons, anything wrong?

slim hound
#

Within the udon behavior graph you have the game object variable set to sync

#

You don't want that

frank lily
#

lemme seeeeeee

#

how did that happen wtf

#

ok i changed that hope it works

#

will check back soon

frank lily
#

it worked thank you very much!

#

was there anything else wrong? xD

slim hound
#

If you launch the game with --enable-debug-gui and --enable-sdk-log-levels you can open the log menu yourself by pressing Right shift Tilde(~) and 3

stray junco

@floral dove
thank you MOMO 👍

frank lily
#

o ok

#

Hi doing some Networking! but i have a small problem the code is working no errors and don't see any problem's on the code maybe it's just me, but
EventFromUdon.SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, "OnInteract");
This is the line that's not working at all
EventFromUdon.SendCustomEvent("OnInteract");
This line that's the same but local works

EventFromUdon is a different UdonBehaviour and on that UdonBehaviour i have a OnInteract

#

i did some debug and i got this

#

so the event is not giving me any errors

#

i created a new Event and i did a debug.log on it, i'm not getting the debug.log on the terminal so it's something like they are not able to talk but it works if it's local

#

i don't understand it

#

And with Cyan Emulator it works

solid sluice
#

i manage to fix it by creating a new function

    {
        EventFromUdon.SendCustomEvent("OnInteract");
    }
#

and then send that function global it looks like it works like this

opal dew
#

Is there a way for a world to observe and react to player voice? I'm thinking about features for a broadcast studio and automatically switching cameras when different people are speaking. I'm just not sure if Udon has visibility into any of the voice data.

torn pendant
#

Vr chat upload is broken for me can't upload anything.

Uh oh something wrong vrc pipeline etc.

Detach and checked my blueprint pipeline.

Doesn't work.

#

Tried importing creating a new still same

slim hound
#

If that doesn't work you may need to contact support

torn pendant
#

I did that too

#

I get a red string that says could not authenticate.

#

Internets fine too.

slim hound
#

You could try VRChat SDK > Utilities > Clear cache and player preferences but its likely you will need to contact support

torn pendant
slim hound
#

Yeah so could likely be something on VRChats end that you would need to contact support for

cold raft
opal dew

#

i know some music worlds analyse sounds to turn lights on and of, i think there is some wave analysis inside unity we can use

slim hound
#

As far as I know you would need to use cameras to tell if a player was speaking

#

Worlds use AudioSource.GetSpectrumData for music

#

Can't use that on players

shadow tundra
#

Hello, why is the VRCPlayerApi.TeleportTo sometimes blocked by the MeshColliders?

cold raft
#

I doubt it is, maybe it only looks like that

shadow tundra
#

I got the camera teleported and the player still on place

dapper lion
#

so the other day. i sort of calculated how many udon behaviours 1 of my worlds have been using and it was around 5200 and was curious is this caused performance issue, theres a lot more misc components but i was wonder what effectx udon behaves do

cold raft
#

there is no set performance cost for each behavior it mostly depents on the code

dapper lion
#

oh

#

looks at 600 unique udonsharp and 400 graphs

#

hopefully theyre optimized lol

#

i also saw the other day "udate loop" concerns. and i abuse the update and im wondering like. how much should i be concerned

cold raft
#

a lot, any code in an update event directly delays each gameframe with by few miliseconds

dapper lion
#

wait. a few ms oh no

#

in cpu time?

cold raft
#

maybe its nano seconds i dunno

dapper lion
#

but cpu time is being delayed?

cold raft
#

well yeh the code gets executed each frame

dapper lion
#

cus iirc. the world im referencing has 1000s of lines utilizing the update

#

if its nano seconds. ill be fine, but then: mobile hardware

slim hound
#

Both units are a bit off lol

#

I wish Udon only took a couple of nano seconds to run code

#

About 11ms per frame to hit 90fps is needed

shadow tundra
#

I added teleportation in a queue variable and call teleportation during update for it to work correctly

dapper lion
#

so like 0.1 ms?

slim hound
#

For an udon behavior? It would depend on what the udon behavior was doing as Jarno said

#

An udon behavior that isn't doing anything should have less overhead than 0.1ms

#

Even an udon behavior running an update with a couple of functions should still be less than 0.1ms

dapper lion
#

ok

pallid mango
#

I don’t believe udon behaviors use any cpu time if no event is being called? They are basically subscribing to events. They don’t need to be constantly checked.

slim hound
sinful slate
#

Someone correct me if I'm wrong: when instantiating an object from a prefab, this one cannot get a synced vrcpickup, since it is only created locally and other clients wouldn't know what to sync it with, right? So when you want synced pickups, they need to exist on build time?

wanton oxide
#

pretty much

#

there are ways around that but its veeery complex

sinful slate
#

Fair enough, I do have a limited number of objects, so I guess I just gonna pre-create the pool 🙂

hoary echo
#

Is there an SDK3 prefab for the stripper poles that allow anyone to dance? I need it for, uhh... Things.

cold raft
manic yarrow
tribal meadow
#

anyone know if there is an udon prefab for a button that allows you to send a URL to the video player (example: you click a button in world and it plays a video with instructions, or another button to play a different video etc)

dapper lion
tribal meadow
#

sort of...like I wanted to make a few buttons with the URL's already on them, so you can just select it and it plays, rather than having to try to copy and paste URLs.

dapper lion
#

ye, pro TV has a event that can be used to play a custom URL

tribal meadow
#

hmm not finding that one anywhere

slim hound
manic yarrow
#

turns out it's terrible and shouldn't be used

slim hound
#

Built in seat controller?

#

I wasn't aware there was one

#

But depending on how you want your stations to work for VR/FBT you might want to look into the tracking controller

stray junco
#

is navmeshing for npc roaming possible in udon?

cold raft
#

Yes

opal dew
#

I know if I read a person's head location, I can see if they've moved iRL even if their player position origin hasn't moved. If they have used a playspace mover to clip in to a forbidden area of a map (authorised persons only, etc), will that also update that value? I want to send them back to spawn if they try and clip themselves in to forbidden areas.

cold raft
#

I know the zombie tag map does that. Not sure how its implemted tho

opal dew
#

Kind of like when you try and exit a Multiplayer map in an FPS. HUD warning to leave the area, slowly turn red then 'pop'.

#

And if they keep trying it, then the they will be dropped in a timeout box very far away. XD

grand temple
#

if you get bone position, then you will get the avatar's position. If you get tracking data, you will get the true camera and controllers

#

but that only applies to the local player. If you try to get this for remote players, trying to get the tracking data will just give you the bone positions

opal dew
#

I can't remember which I used before when I wrote some code to generate water splashes in response to iRL player movement while they were stood in a pool.

#

Ah.. That's useful to know, I guess head bone position is what I want here as that should move in both iRL and playspace moving contexts.

grand temple
#

you want to compare the distance between the head bone and the head tracking data. If it's too far, they're doing something weird

opal dew
#

Ah! Okay! And I'll need to do that on the local player's own machine as anyone else won't see the 'cheat' values.

#

Thanks! :) I've been tasked to create a performance space and they want to prevent stage, backstage and technical booth invasions. XD

hushed gazelle
#

With network ownership, is it faster to just let the Collision Ownership transfer do its thing on the VRC Object Sync when an object is picked up, or to deliberately specify the owner in the Udon Script on a Pickup event? (ie; Pickup -> set owner -> local user)

coarse parrot
hushed gazelle
#

Cool, good to know.

radiant junco
#

Is there any requirements for an UdonBehaviour to Send Custom Network Events? I have a specific UdonBehaviour that for some reason just doesn't send custom network events... If I use a normal Send Custom Event, it works fine. This started happening after the last SDK update but I haven't been able to recreate it on another Unity project.

slim hound
radiant junco
#

I've tested other names tho, still nothing

slim hound
#

Are you doing this in graph or U#?

hushed gazelle
#

Just to check, is having a bunch of scripts that only activate on a button press going to add much to a world's overall load? I'm just trying to keep things relatively optimized, but I'm wondering if I can get away with adding a script to each button in a menu to make how they work a bit more optimized vs the buttons sending a command to the controller script directly without extra overhead.

#

Just to clarify a bit better; It's a difference between Button -> Controller UdonScript custom event, and Button -> Button's UdonScript -> sending a variable to a shared function in the Controller UdonScript.

radiant junco
slim hound
hushed gazelle
#

Cheers. I'd thought as much, but just wanted to make sure.

slim hound
# radiant junco U#

Check the unity console or in game log to see if it says anything about it not working?

radiant junco
slim hound
#

Do you know if it works in editor? or neither editor or in game?

radiant junco
#

Here's the relevant code

public void EquipODM()
    {
        if (equipped) return;
        Debug.Log("Equip");

        if (!localPlayer.IsUserInVR()) desktopOverlay.SetActive(true);

        Networking.SetOwner(localPlayer, gameObject);
        Debug.Log("Local is pool owner: " + Networking.IsOwner(gameObject));

        currentOdm = objectPool.TryToSpawn().GetComponent<ODMGear>();

        Debug.Log("Current ODM: " + currentOdm.name);

        Networking.SetOwner(localPlayer, currentOdm.gameObject);

        //This doesn't work
        currentOdm.SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, nameof(ODMGear.Equip));

        //This works
        //currentOdm.sendCustomEvent(nameof(ODMGear.Equip));

        if (localPlayer.IsUserInVR()) currentOdm.EnablePickup();

        equipped = true;
        Debug.Log("Finished EquipODM in ODMManager");

    }
#

I also added a Debug inside Equip to see if it runs at any point, but nothing

timber lion
#

On mobile so it's hard to read your code but. Is Equip() public

radiant junco
#

Yep

timber lion
#

oof yeah that's weird then

radiant junco
#

Yeah... idk why a regular SendCustomEvent works but not a networked one. Worst part is that I can't recreate this in a different project

fiery yoke
#

Can you show the Equip function as well? @radiant junco

radiant junco
radiant junco
# 
public void MyCustomEvent()
{
    Debug.Log("MyCustomEvent");
}

This runs:
SendCustomEvent(nameof(MyCustomEvent));
This doesn't:
SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All,nameof(MyCustomEvent));

i just did all the steps again and it worked

#

idk

#

its weird kek

lilac hatch
#

is there a way to change a text value into a float ?

#

Tried to do it like this

#

but i simply get an input string was not in a correct format

#

and im unsure on how to put it in the right format

dapper lion
#

like a slider string input?

fiery yoke
lilac hatch
#

@dapper lion yep

dapper lion
#

tries to remember how to do that in graph

fiery yoke
#

You do that by getting Slider.value

dapper lion
#

im not sure. updating strings might be a helpfulhelper query

#

silder.value -> string.text? (not familar eith node names sorry lol)

fiery yoke
#

I have no idea what theyre actually trying to accomplish.

dapper lion
#

i think they want the calue of a slider to appear as a number

lilac hatch
#

Nope, I got that part.

#

The thing is ; The "slider" I'm using is a physical one

#

There's no actual slider component

fiery yoke
#

Define "physical"

dapper lion
#

ohhh. is it techns slider?

lilac hatch
#

yeah.

#

I'm just trying to use the Text as a float basically

fiery yoke
#

They should have API that gets you the value

dapper lion
#

ah. he literally explained that to me just yesterday for final teating lol

fiery yoke
#

I wanted to make my own PhysUI as well at some point. But then kinda got busy with other stuff

dapper lion
#

so are you trying to get the value onto text form?

lilac hatch
#

I have a Textfield with a value in it going from 0 to 1 and a SetFloat for a material

#

I'm trying to use the said Textfield as a value

dapper lion
#

so like backwards? so if you type a number. it sets that value/float

lilac hatch
#

ye

fiery yoke
#

You mean an InputField then

lilac hatch
#

basically what i'm trying to do

fiery yoke
lilac hatch
fiery yoke
#

try "get text"

dapper lion
#

what about “inputfield”(?)

fiery yoke
#

I mean yeah you can also just get the inputfields value directly. Which is "better"

lilac hatch
#

It's sadly not an inputfield ; get text is not causing anymore crashes at least

dapper lion
#

inputfields crash?

fiery yoke
#

I genuinely have no idea what youre doing lol. You grabbing some input, but its not an input field?!

lilac hatch
dapper lion
#

ye my brain is also controupulating now

#

ok so slider and text value

#

wait. are you trying to make multiple sliders match eachother?

lilac hatch
#

Slider going left/right ; value on top left is calculated depending on where the slider is on an axis (z if i recall ?) there's no actual slider component on the entire thing

dapper lion
#

correct

lilac hatch
#

Nope, i'm trying to use the slider to change one value of the material on my mirror (transparency)

dapper lion
#

ah. is it meta mirror or sadbluecat mirror?

lilac hatch
#

And for that I need to use the said value on the top left if i got it right, which is a simple text

dapper lion
#

i would contact techn/source of it. he explained the slider to me in detail. but it was also like 3 am for me lol

#

but that idea you have makes more since

lilac hatch
#

VRCPlayersOnlyMirror for the mirror yush

dapper lion
dapper lion
#

sadly i have not had to do something like this before. i feel like float number grabbing should be possible. but techn will most likely have a more solid solution compared to mine. as i rarely use sliders

lilac hatch
#

Might actually suggest that for the demo scene since I feel like a lot of people might have this usage for sliders tbh

#

But... first I gotta finish my stuff eheh

#

Thanks for the help both of you tho !

fiery yoke
dapper lion
#

i feel like he did

#

at least he told me about it. cus i was trying to learn sliders but with UI so i wasnt 100% on any of it

#

i was never quieneopes from physical sliders

lilac hatch
#

Well ; I restarted unity because stuff was glitching a bit and the Get text work.

#

I'm legit clueless but

#

it is what it is i guess

dapper lion
#

sounds legit, have a good day

So uhhhh, first time making a map, placed a VRCChair3 (test chair provided by Udon) to test seating and when i build and run it doesn´t appear

But i have this

Those errors would be an issue yes

#

Clean udon SDK install? Current, wasn’t updated over an older one, etc?

It looks like Udon is demanding the Cinemachine component, I think that's a package that you get from Unity's package manager.

# radiant junco Is there any requirements for an UdonBehaviour to Send Custom Network Events? I ...

I've been poking at this some more, the issue is only the specific target UdonBehaviour (ODMGear) that isn't doing anything when sending the CNE. I tried with a new test U# script and that went fine. I kind of want to just make a new script and copy paste the code but there's quite a few references I would have to manually drag...

//This doesn't work
ODMGear.SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, nameof(ODMGear.Equip));
//This works
test.SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, nameof(test.TestEvent));

It doesn't matter what I type into ODMGear, it's not running any CNEs...

#

Wait never mind I don't know which UdonBehaviours run and don't run CNEs... it seems random??

Make sure you redo all the steps too

wise bay

ty @amber crow

amber crow
#

Backup, import the new sdk in the backup, keep an empty scene loaded only, close unity, change to 2019.blablabla, launch it, say confirm yes and yes
Wait a bit and you ll be good

#

Np!

#

It can be confusing as the guide doesn't say where to grab the u2019 sdk

soft mountain
#

So, regarding networking, is there anything I can go read to understand which callbacks are only called locally vs which are called on every instance? Stuff like OnPickup(), etc

grand temple
#

if it's not specifically an event related to networking, it's probably not going to happen networked

#

however, if an object is synced then it will probably trigger OnTriggerEnter for everyone. Not because it's specifically synced but because everyone sees the object enter the trigger

grizzled shuttle
#

is there a way to get who triggered a midi note event?

grand temple
#

the midi event will always happen for the local player only, so it's up to you to sync it with other players

grizzled shuttle
#

Oh, good to know

gloomy swan
#

anyone know what this error is? getting it after i updated my unity Assets\Udon\Editor\ProgramSources\UdonGraphProgram\UI\GraphView\GraphElements\UdonGroup.cs(2,41): error CS1002: ; expected

grand temple
#

line 41 is missing a semicolon

#

or is it line 2, I forget. One of those two 🤔

gloomy swan
#

humm

#

let me see

#

looks like it was but it did not resolve the issue. this is a file from the sdk

#

now it is at 4,30

#

the devs might want to have a look at there udon portion of there sdk. there seems to be a few errors

grand temple
#

oh, right this is a file in the SDK. In that case you have the wrong SDK. Please follow the instructions exactly when upgrading a project from 2018 to 2019

gloomy swan
#

i did

grand temple
#

if you have that error, then you missed a step

#

make sure you have the SDK made for unity 2019

One of your udon scripts is not compiling. Are you using Udon graphs or Udon Sharp?

#

And in other news, I'm having a smidgeon of a problem myself. Been a hot minute since I messed around with pickupable objects, and for whatever reason, I no longer see a "synchronize position" check, and am curious what I need to do to make that appear or work now.

pure basin
#

That checkbox has been replaced with the VRCObjectSync component

vernal maple
#

AHA

#

Alright thanks.

#

Next question. I am aware that VRCinstantiate cannot be used on objects with Udon Scripts attached. Can a GameObject with VRCObjectSync be instantiated?

pure basin
#

Instantiated objects can't be synced. You can use VRCObjectPool as a substitute for instantiating synced stuff

vernal maple
#

Alright so we still have that limit. Gotcha gotcha. Object Pooling some monsters for the sake of this then.

#

can't wait to make pathfinding for them. ._.

Thanks for the help. Back into my hidey hole.

Check your scripts to see if you have any red squiggly lines under any lines of code you may have added.

Else I would make sure that you have the most up to date SDK and U#

#

could build my project finally with v0.20.O U# though..
and got broken with the last update

unborn hornet
#

In graph, I want to call SetProgramVariable on another graph passing the current udon graph as the value. How would I get the reference to the current udon behavior without having an empty UdonBehavior public variable?

nimble ridge
#

There doesn't seem to be anything wrong with the scripts

floral dove
unborn hornet
#

And if there are two behaviors on a single game object where the script isn't the first in the component list?

floral dove
floral dove
unborn hornet
#

Which is what I was wanting to avoid so I don't have people put a custom graph into that slot and break things.

#

Cause this is related to a distributed asset.

#

canny time

floral dove
#

The put the UdonBehaviours on two separate objects, or combine their logic?

unborn hornet
#

That breaks certain separations of concerns for certain logic. Not to mention not having a dedicated node for "Current Behavior" is quite un-intuitive for newer users because there is already Const <Primitive> nodes as well as Const Null and Const This (GameObject). It would make sense for there to be a corresponding Const UdonBehavior or similar that always referred to the current behavior irrespective of any other behavior's concerns.

floral dove
#

You can try making a non-public UdonBehaviour variable. It might default to this instead of null, not sure and I'm not at a computer but worth a quick test

unborn hornet
#

Unless there was a change to how udon serialization works recently, private variables being not serialized will default to null as I have tested that before (like 6 months ago probably)

#

I'll test again just to make sure.

#

Alright, appears that the private udonbehavior does actually work.

#

Good to know.

floral dove
#

I think a clearer const or this node for UB is a good idea still, fwiw

unborn hornet
#

Yea. Good to have consistency. I'll pop a simple canny for tracking.

Does anyone know how to play an animation when a player join a map ? I'm rlly new in Udon and its been 2h now since I try to find something to help me like tutorials but they're all outdated , and the Vrchat udon page seems also outdated with the description of each nodes

unborn hornet
#

Something like this?

unknown.png
#

If you want it to occur anytime ANY player joins (like join notifications or something), just remove the LocalPlayer, Equals and Branch node.

pure parrot
#

oh

#

uh do i need to make a variable for that ?

floral dove
pure parrot
#

nvm i'm a huge noob , i coudln't find a specific node cuz i didn't added an animator variable

#

nice and I got a new error

#

anyone already had " NullReferenceException: Object reference not set to an instance of an object
VRCSDK2.RuntimeWorldCreation.Start () (at Assets/VRCSDK/Dependencies/VRChat/Scripts/RuntimeWorldCreation.cs:82)
"
and how to fix it ?

#

Does anyone know how long a string can be in Udon? Non-synced, just local only. One of my strings are being cut off in the unity debug it seems

grand temple
#

many thousands

quartz meadow
#

just realized my function wasnt generating the full string, was my end lol

grand temple
#

I don't know if there is a limit

quartz meadow
#

but thanks for the info

#

unity stated like 16k I think

grand temple
#

that's the case for inputfields, yes

#

but udon can sync somewhere around 60k

warm goblet
#

Likely a simple question, but I have a gameobject variable, I've set it to a gameobject with a rigidbody. How would I get a reference to that rigidbody in Udon?

#

wait actually this is working now...

#

I guess ConstantForce doesnt work, but force does...

vernal maple
#

Getting my mind caught in a loop here. I have an enemy, a weapon that deals damage, a player that did the damage. The weapon script ray casts to see if the target was hit. Now how should I inform all clients which enemy was hit and how much damage to apply? Right now I figure getting the enemy's script via the collider's gameobject script component is the way to go, but then how do I inform that script which player did the deed?

#

I'm thinking 12 different pings (based on player index assigned on world load.), but I feel like that's a mess.

grand temple
#

yeah, unfortunately right now sendcustomnetworkevent does not support variables for extra information, so a common practice is to just have a new network event for every different possibility

#

you can construct the network event dynamically because it just takes a string, so you can say "ShotByGun" + gunIndex which will result in "ShotByGun1" through "ShotByGun12" or whatever. But you can't construct the endpoints dynamically, so you need to have a bunch of network events ready to be activated. Rather than duplicating that code multiple times, if you're using udonsharp you can do something like this to turn it into a variable that you can do things with

    public void ShotByGun2()
    {
        ShotByGun(2);
    }```
vernal maple
#

Regrettably that was what I was afraid of. I'll need to figure out which way to handle this, either index of weapon, or index of player firing the weapon.

#

Thanks~

finite gorge
#

does anybody know why im not getting the sync object position check box on my udon behaviours? because currently the objects aren't being seen picked by other players

grand temple
#

that checkbox was removed. Instead, you should now use the objectsync component

finite gorge
#

the udonbehaviour script for it?

#

and can it be applied to the empty object that holds all the objects, or does it have to applied to each object

manic yarrow
#

Can anyone explain why this graph might be causing serious framerate issues?

unknown.png
#

I have some ladders in my world that teleport you to the top when you interact with them, and the framerate tanks if I don't disable them

grand temple
#

there is absolutely nothing about that that could cause issues. Are you sure there's nothing else?

manic yarrow
#

and those ladders are the only objects that have that script on them

#

I thought I had the 11fps bug, but it turns out it's the ladders

grand temple
#

what else do the ladders have?

manic yarrow
#

a convex mesh collider so you can use them

#

and that's it

grand temple
#

there's gotta be something else, more details ¯_(ツ)_/¯

manic yarrow
#

I'll show you all the components

#

This is everything

unknown.png
#

wait

grand temple
#

I can't imagine that would cause framerate problems, but why is your transform synced?

manic yarrow
#

I was just going to say!

#

I saw syncNone

#

I swear if this is the whole problem

grand temple
#

I doubt it

manic yarrow
#

I've been trying to fix this for hours

#

I managed to narrow it down to these ladders, everything else with udon can be enabled no problem

manic yarrow
#

but only if more than one person is around

#

One person on their own is fine, if there are 2 people it will lag the first joiner

grand temple
#

oh, that's good to know. Could be that then

manic yarrow
#

if the first joiner leaves and then rejoins, the lag goes to the person who stayed

#

so I can only assume it's an ownership thing

hushed gazelle
#

Just out of curiosity, is it possible to have multiple video players in a world?

manic yarrow
#

I can't believe it

grand temple
#

weird

manic yarrow
#

I can't believe a single check box broke the framerate for people

#

and the worst part is, it would make people run at 11fps

#

the exact framerate that's involved with a famous bug

#

so here I was thinking I had the 11fps bug

grand temple
#

why is it called the 11fps bug? It's not like a lock at that framerate. Call it the vram bug, because it's related to vram. If you lower steamvr resolution you'll hit a point where your fps will suddenly be better

hushed gazelle
#

It's called the 11fps bug because it consistently makes people run at 11fps and not everyone knows what VRAM is.

grand temple
#

it's not 11fps though, that's a totally arbitrary number that people stuck with

hushed gazelle
#

It doesn't really matter when everyone knows EXACTLY what it means though.

manic yarrow
#

How hard would it be to create a buoyancy system with udon?

#

a constant upward force that I can apply to objects once they go below a certain height

#

That way I could make things float on water for example

slim hound
manic yarrow
#

Where would I start?

slim hound
#

Just seeing if I can find a setup I made some time ago

manic yarrow
slim hound
#

What part were you having issues with?

manic yarrow
#

I didn't even know where to start, I was trying to figure out how to apply forces

#

My original plan was to have an invisible plane just below the water's surface that only collides with certain objects

#

but I thought it'd look nicer to do it properly

slim hound
#

Found it, though it does a little jank

manic yarrow
#

how so?

#

are we talking breaks-the-game jank or slightly-weird jank?

slim hound
#

Suppose it's not too bad it's just there would be better ways to do it

manic yarrow
#

Is there a way to adjust what floats and sinks?

#

the mass of an object I'm using is very high because of something else it does

#

about 100 or so

slim hound
#

That setup is built assuming mass is around 1

manic yarrow
#

The object is one of those swimming rings, and I had to increase the mass to get it down a slide at a good speed

slim hound
#

You can do RigidBody.Getmass and go from there

manic yarrow
#

Looking at the graph, would I be changing the multiplication node attached to distance?

slim hound
#

Yeah presumably that would be the simplest way to do it

#

Increase the applied force based on mass

manic yarrow
#

Right, just wanted to make sure I was plugging nodes into the right thing

#

I'll be sure to credit you for this by the way, I've needed a lot of help with this world because physicsy water stuff is weird

slim hound
#

Oh one thing about it is that if you move the game object on the y axis you will want to unparent the water height transform as its checking y in local space

manic yarrow
#

works pretty well as-is

#

all I did was replace the set value of 20 with a multiplier for the object's mass

#

so now there's an adjustable variable built-in

#

Interestingly, a value of 0 will make the object float in the exact centre of the volume

sly crest
#

Hey! I have a question? I´m new to this so i kinda wanted to know how do i program something to be server-side or client-side?

slim hound
#

You can also set variables like numbers to sync automatically

sly crest
#

Thanks

#

So if i use the **SendCustomNetworkEvent ** method i will make sure everyone in the server sees it right?

slim hound
#

Yes unless you specify it to only send to the owner it will be all players

sly crest
#

Great!

#

Thanks

Hello! Before trying this, I want to know if it's even possible doing this; so, as I said in previous questions, I'm making a card game, I have an object pool where I store all the card, but I was thinking to have another object pool where the used cards can go, so I can spawn only new cards. Is this even possible or it's just better to change the name of the card/using a layer and check if it was not used before spawning it?

floral dove
dawn plover
#

Oh, so if I return a card it will not be spawn again until it reach the end of the deck? In that case it's easier than I thought, thank you for the help!

manic yarrow
#

I just uploaded my world finally, and it turns out that you can grab seats while you're sat in them and fly around.

#

How would I make it so that you can't pick up an object that your seat is parented to?

slim hound
manic yarrow
slim hound
#

VRCPickup

manic yarrow
#

Is there a node specifically for the parent of an object I could use?

#

It would be faster for the graph to automatically disable a parent instead of having to set it for every object

vernal maple
#

I have an absurd question especially for VRChat. Can VRC and udon use NavMesh and NavMeshAgents from Unity?

grand temple
#

yes, absolutely

vernal maple
#

O_O

grand temple
vernal maple
#

Aight if people see a Killing Floor clone in VRChat next week, you know who made it.

manic yarrow
#

I was going to make it a variable but the set pickupable needs an instance specifically

vernal maple
slim hound
#

Though if the pickup is the direct parent of the object you could just get components in parent

manic yarrow

#

Should work?

they actually reached the point where they could manoeuvre

feral valve

I can't type a event name anymore

event.PNG
#

I restarted the project several times and nothing fixes it. using newest sdk

grand temple
#

yes, that's how it's supposed to work now. It automatically finds all events in the udonbehaviour and puts them in the dropdown

feral valve
#

So how do I add one?

grand temple
#

add a custom event node and give it a name

#

and the event needs to do something, it can't be on it's own

feral valve
#

ahh, thank you. I know it shouldn't be alone, I just snipped it on its own to show

Guys i happened to check my vrworld toolkit and it says that this asset is taking 32 mB, thing is, i deleted it! how is it still here?

tranquil summit
#

hey! is there any way to use unity tags with udon? i want to change all objects that have a specific tag at one time

#

i should probably specify in the graph editor ig, but if its not with the editor then i'll try and figure out U#

dawn forge
#

Sorry I don't have a graph, here is a U# example

unknown.png
tranquil summit
#

ah, no worries, thank you anyhow!

dawn forge
#

Let me see if I can whip something up hehe

tranquil summit
#

oh, that'd be great lmao

#

im mostly doing it to change the material of a bunch of objects at once to fake time of day changing

dawn forge
#

Ughh the graph doesn't give me the tag property in node search, if you can search too, it's a component type.

tranquil summit
#

yeah, i was grooming through trying to see if i could find it, but i wasn't sure if i just wasn't looking in the right place

dawn forge
#

Yeah, it would HAVE to be under gameObject category, because it's a property under gameObject.

unknown.png
tranquil summit
#

well fuck, then

#

oh well

dawn forge
#

Well you can mix and match UdonSharp and graphs, you may just need have a bit of flexibility just for the tags.

tranquil summit
#

yeah, working with raw code just makes my head spin lmao

dawn forge
#

You can still call methods and exchange events with U# and Udon graph scrips, ultimately they both compile to the same bytecode that Udon parses and executes with.

#

I could just write a small script to add, set, and remove the tags. You'll call it through a gameObject reference. I can send it to you. Downside is you need to add the UdonSharp package to your project.

tranquil summit
#

nah i already have it

dawn forge
#

Awesome, good luck on your project.

tranquil summit
#

mhm, thank you

dawn forge
#

Update to the tag stuff: It's not exposed to Udon 😦 booo

tranquil summit
#

i was literally in the process of coming here to say that

dawn forge
#

But you can just sync the variables and track it that way

tranquil summit
#

hmmm

#

ig to break down what im trying to do more, im trying to change the material on a whole bunch of different game objects around my map at the same time in order to give them different appearances to fake a change in time of day, as well as changing the skybox (which i can do that part)

#

something tells me that for performance's sake it isn't a good idea to set an udon behavior to run on like 50+ game objects all at the same time perchance? bc i could just do a custom event that triggers on every single object that needs to change
but that sounds cpu taxing

dawn forge
#

Well you're wanting real-time changes.

You either sync a variable, or have each object listen for the broadcasted event. I'd say to events because you don't need to have Update() do if's against a sync'd var every frame.

tranquil summit
#

so just two udon behaviors, one that has a send custom event node, and the other has an event custom node right?

dawn forge
#

Correct. Have each custom event node for each material you're gonna switch to.

tranquil summit
#

alright yeah, i got that set up, but fsr the one event doesn't seem to be broadcasting the event? idk if im doing it wrong but i just have it "interact > send custom event" and another one is just "event custom > material change"

dawn forge
#

Are you setting the owner of the object?

tranquil summit
#

i don't exactly know what you mean, tbh im quite new to udon

#

like with the instance node?

#

not node, the input on custom event

dawn forge
#

You'd want to be the owner of the gameObject that runs the broadcasting behavior, so it can be manipulated by your client.

The same applies to your interact button.

#

Lookup Networking.SetOwner and then input will be Networking.LocalPlayer, and the obj will be this.GameObject in the node.

tranquil summit
#

okay, thank you so much man

dawn forge
#

You're Welcome. Sorry I am not a node graph guy haha

tranquil summit
#

no you're fine lmao, i wish i knew more about udon in general so this has been a huge help

dawn forge
tranquil summit
#

yeah, i've been peeking at that whenever i find something that i think i can play with, especially since the graph has a link to what each node does

#

also just to clarify, the networking.setowner and all has to be on both behaviors?

dawn forge
#

I know some of the nodes will have "?" at the top corner, will also take you to the Unity page to describe the function.

#

Not necessarily, the other behaviors will always listen even if it's under another person's ownership within the network 🙂

tranquil summit
#

gotcha!

#

so just to double-triple check, this is basically what it should look like?

unknown.png
#

or have i had some critical misunderstanding lmao

dawn forge
#

Looks correct, I am trying to recall what instance is for lol

#

Trying to transelate my code to a node graph

tranquil summit
#

apparently instance is if you want to target a specific udon behavior

dawn forge
#

Ah ok, then that looks correct. "This" is already targeting the object the behavior runs upon.

tranquil summit
#

alright, and then this is the other end

unknown.png
dawn forge
#

Looks correct, give it a spin!

tranquil summit
#

hm.
that's worrying then

dawn forge
#

P.S. if you're not using it already, check out CyanEmu. You can run Udon in the Unity Editor. https://github.com/CyanLaser/CyanEmu

GitHub
CyanLaser/CyanEmu

CyanEmu is a VRChat client emulator in Unity. Includes a player controller with interact system. Works with SDK2 and SDK3. - CyanLaser/CyanEmu

tranquil summit
#

yeah i've got cyanemu

#

so, then something's wrong bc it's running the code on my test object and changing the skybox, but it isn't changing the test tree i have set up

dawn forge
#

What's the test tree look like?

tranquil summit
#

typical

unknown.png
dawn forge
#

It's mat is not changing on par with the rest?

tranquil summit
#

what it should turn into

unknown.png
#

i made it absurd to make it obvious lmao

#

but yeah no the mat isnt changing at all

dawn forge
#

Can you have your tree behavior call a Debug.Log and see the console if it's reaching the function?

tranquil summit
#

one mo

#

itttt doesn't look like its reaching it

dawn forge
#

Can I see the graph?

tranquil summit
#

this is on the tree

#

Hey all, what's the right way to immobilize a player when they get in a seat so that they can use their joysticks for udon stuff?

dawn forge
#

Did you mean to not have a "_" at the start of the name?

tranquil summit
#

yeah, according to the wiki you use _ on custom network event if you only want it to play local apparently

dawn forge
#

Yeah, it's not network callable hehe... so I am confused a bit why your earlier graph with the skybox works fine.

#

Have your custom event directly call the debug.log, and see if the set material is the issue.

tranquil summit
#

alright

#

im assuming that "success" should just appear in the unity console
in which case still nothing

dawn forge
#

And you already tried with "_Day"? because your earlier script is looking for that event.

tranquil summit
#

oh yeah no i double checked that i removed the underscore

#

is it possible its just something that might not work in cyanemu?

dawn forge
#

I mean if your skybox and other materials are changing, it should not be different with the tree.

tranquil summit
#

yeah

dawn forge
#

Did you compile your behavior and is it enabled on the inspector?

tranquil summit
#

yeah

#

i can directly use cyanemu to just play the "Day" event and that works fine

dawn forge
#

I am looking at the graphs again, and doing some plain event stuff to see my outcome.

#

Kinda nuked my graph...

#

Hehehe... my Udon noodles are broken.. P.s. Momo, I am on 2019.

unknown.png
tranquil summit
#

oh yeah it was doing that to me too

#

im also on 2019

dawn forge
#

Time to make a new batch of Udon(Kidding, but it'll still work I am sure).

tranquil summit
#

lmao

#

im gonna try build & test rq, i doubt it'll be any different but its worth a shot

#

as expected yeah, nuthin

dawn forge
#

Ughh how do I feed a string into debug on the graph :S could you send me the assembly?

#

Or asset files?

tranquil summit
#

oh thats long

dawn forge
#

Yeah you can just send the asset files.

tranquil summit
#

sure thing

dawn forge
#

Ughh how do I feed in a string to message lol

tranquil summit
#

like for the debug.log? it just connected for me

dawn forge
#

Want to have a screenshare via DM's? Could speed up the debugging process.

tranquil summit
#

i used string const

#

and yeah sure, one moment

feral valve
coarse parrot
feral valve
#

Followed along with tutorial. Got it to pickup and at a certain point grip. just to show settings on object with the udon graph. I just assume the video is outdated cause now it's showing options not in tutorial

graph.PNG
#

so it pretty much just stays in hand when I click it, and using the use button down and up doesn't do anything

#

Like his only has value with checkbox. and new one has send change

slim hound
#

The bool value not being directly exposed on the node itself could be considered a bug actually

#

Though if you go create Boolean > Const Boolean and plug it into the value option on the Set isActive nodes it should work then

feral valve
#

how would I do that? I tried just adding it and connecting to value, but after I used it. it wouldn't stop.

slim hound
#

Screenshot the graph?

feral valve
#

I know why it's not working, cause its not saying to turn on or off with use button

use.PNG
#

its just setting the value

slim hound
#

The branch you have should prevent it from firing depending on the boolean value

feral valve
#

I just figured it out, I needed that sendchange to be toggled on

slim hound
#

That shouldn't affect anything you are doing

#

I'm guessing the graph didn't compile until you made that change

feral valve
#

ah you're right. unchecked it and compiled. still worked fine.

#

thanks for the help!

slim hound
#

@floral dove Is this change intentional in not having the boolean value exposed on the Set Boolean node itself?

unknown.png
cold raft
#

it still seems exposed

#

oh i see what you mean

feral valve
#

So something I can't find, but assume is simple. respawning a object. how can I set its value to original spot.

cold raft
#

that was added recently, the VRCObjectSync compoment has a method to move the object back to its original position

feral valve
#

that makes it so much easier then what I was trying. literally just plug interact to respawn. thanks!

respawn.PNG
slim hound
#

You will need an object sync component on the game object for it to work

#

Which from your previous screenshot doesn't look like you had

feral valve
#

I added that just now. still just realized, how can I use another object to respawn it

slim hound
#

You will need to add multiple of those game objects for multiple people then

cold raft
#

simpest way to make respawn happen from a different object, is to have a public gameobject variable like name it target on your interect behavior, then you can just use the target do get component typeof(VrcObjectSync) and call respawn on it

feral valve
#

I'm really new to this, so I don't know how to set it up

#

here's all I can get

respawn_2.PNG
cold raft
#

interact, goes to GetComponent

#

on get component, set instance to target, set type to VrcObjectSync

feral valve
#

Still can't figure it out and now it's beginning to be daylight and I need to get some sleep

burnt moth
#

how would I make it when I click on trigger it plays animation

#

just like a trigger that activates mirror but instead of activitng anything it plays an animation

#

on a certain gameobject

fickle stirrup
burnt moth
#

that's basic csharp

#

I know how to use csharp but look I don't know how to do it in udon

#

do I replace the gameobject in the udon graph with an animation?

coarse parrot
#

You do the same with Animator.Play udongraph node though.

burnt moth
coarse parrot
burnt moth
#

well I am typing animation and play into the node search bar

#

and it doesnt pop up

coarse parrot
#

It's "Animator"

#

And you also need to attach an animator component in the game object you want to play an animation too.

#

Also note that animator isn't the same thing as animation.

burnt moth
coarse parrot

#

?

now

like this right

a2774c53eb47be3cbc7a7b12a23bca0e.png

Yes. Optional, adjust the layout so it looks good.

burnt moth
coarse parrot

coarse parrot
burnt moth
#

wut

#

do you know how I can do that

coarse parrot
#

You can create a public variable with Animator type.

#

Just select Animator instead of int or bool or float when you're creating one

burnt moth
#

but how do I attach that to the actual udon place

coarse parrot
#

Drag the variable from the list into the graph

burnt moth
#

like this?

coarse parrot
#

Yes

burnt moth
#

and now it will work automatically if I just drag in the object with the animator on it?

#

it's not appearing in the udon behaviour script

coarse parrot
burnt moth
#

the animator

#

where I need to drag in the animator on the public varible

coarse parrot
#

Does the object have Animator component assigned?

burnt moth
#

no but like

#

there is no public variables

coarse parrot
#

Have you made the variable public?

#

how do I do that

#

I did it

#

nvm

#

wait its still not appearing

#

I checked the public thing so it's checked

coarse parrot
#

Can you screenshot the variable list?

burnt moth
#

it appeared now

#

so its fine

coarse parrot
#

ok

burnt moth
#

but what do I put in state name

coarse parrot
#

You need to create animator controller first and assign to the animator component

burnt moth
#

yeah and I uncheck the animator controller right

#

or the animation will play by default

#

when the world starts

coarse parrot
#

Don't disable the component

burnt moth
#

wutt

#

but else it will play the animation when I start the world

#

I just want it to do the thing when I click on it

coarse parrot
#

You set empty state as a default state. Then add another state with animation in it.

#

Then stateName in Play will be the same name as the state with animation in your animator controller

burnt moth
coarse parrot
burnt moth
#

yers

#

wait

#

I just dragged into the public variable

#

I havent done anything with the statename or added an animation

#

you said I had to add another state but how do I do that in the udon graph, do I just make another animator

coarse parrot
#

You need to edit in animator panel

burnt moth
coarse parrot
#

same name as a state that contains an animation you want to play

#

And you want default state to play nothing

burnt moth
#

does the name have to be the exact same

coarse parrot
#

Yes, exact upper-lower case

burnt moth
#

and do I need to mess with any of the transitions

#

or exit time

coarse parrot
coarse parrot
burnt moth
#

I had to make a new layer since it already has an animation it should be playing 24/7

coarse parrot
burnt moth
#

she's waving all the time

#

the interact one is just going to make her invisible

coarse parrot
#

Ok I see.

burnt moth
#

do I need to drag the stateName anywhere

#

the circle thing next to statename

coarse parrot
#

No. You already assign the name manually

burnt moth
#

so no one else will hear or see if I add sounds to the animation

coarse parrot
burnt moth
#

like npcs

#

I tried using GameObject []

#

but it doesnt work

coarse parrot
coarse parrot
plucky scaffold
#

how about using 'for' or 'foreach' loop to turn off every GameObject in GameObject[]

coarse parrot
#

Yes, an array need to be iterated into each member of the array

manic yarrow
#

What's the node called to check if an object is being held?

burnt moth
#

I am stupid bro

plucky scaffold
plucky scaffold
manic yarrow
#

If you sit in the station, it disables the parent (which is a pickup_

#

but if you're holding the parent, it disables the seat

#

I'm fairly certain I'm missing something, but I don't know where

plucky scaffold
#

way 1. In pickup object, make a new script which get 'OnPickup' and 'OnDrop' event
way 2. In every update event, you have to check 'IsHeld' using 'if' branch and then disable it if variable is true.

manic yarrow
#

which is better for performance?

plucky scaffold
#

I recommand way1

manic yarrow
#

Yeah, I suppose it's probably better to avoid stuff constantly running

manic yarrow
burnt moth
#

cause imagine like 5 mirror connected to one trigger, I want it like that but to my npcs since I need it so people can deactivate them and then activate them again

plucky scaffold
manic yarrow
plucky scaffold
burnt moth
#

I really don't understand how to do that

plucky scaffold
#

oh sry it's 2am here and i turned off my pc

burnt moth
#

Ill try my best to understand

plucky scaffold
#
  1. make a new bool variable A
  2. make 'if' branch that check A is true or false
  3. if A is true -> set gameObject.SetActive(false), set A to false
  4. if A is false -> set gameObject.SetActive(true), set A to true
burnt moth
#

or what do you mean

#

this is how far I've come

6c82d8e6521518600559a0c8d2506aa3.png
#

I made a bool named BoolA

plucky scaffold
#

you don't have to make it public

#

just set it 'true' if initial state of the object is active.

#

hope it helped...

burnt moth
burnt moth

anyone know how I do this?

[ 1. make a new bool variable A

4. if A is false -> set gameObject.SetActive(true), set A to true ]

Hello everyone!
I was wondering if it was possible with the Udon, to create a script so that it could
change a postprocessing variable at tot times in real life.
So you can recreate day and night! Thank you.

#

Does anyone have the 3d mirror asset the one where you have a full 3d representation of yourself?

#

Thank you so much

tranquil summit
#

is there some way to send a custom event between udon behaviors? i have a behavior set to send a custom event, but the other ones don't really seem to receive it

mortal star
#

How would one go about making a world with two different gravitational forces that could also affect other objects?

burnt moth
mortal star
#

You want to do a toggle?

#

Do you use graphs or code?

#

if using code you could do for example:

A = !A;

if A is true it should set it to false and vice versa

burnt moth
mortal star
#

I see

burnt moth
#

this is so far I have come

mortal star
#

There should be a negate function in graph as well

burnt moth
#

with help of someone of course

floral dove

I'll look into it

how do we remove the magazine from the pistols on keyboard please I'm lost xD

tranquil summit
#

what are you even referencing

mortal star
#

I have not used graphs since I discovered U# so I'm out of the loop x)

floral dove
burnt moth
#

Yeah I'll try, does it show how to disable a lot of objects at the same time and then enable it when clicking again

mortal star
#

You could use an array

#

so you can put multiple game objects for example instead of one

#

ok so i understand now that send custom event only works between a targeted behavior or the behavior calling it, but is there a way to make a bunch of behaviors listen for a behavior changing?
like for instance, i click a menu option, and a bunch of elements around the world change

burnt moth
#

Okay I still dont know how to make it work for multiple objects

floral dove
burnt moth
#

any good youtube videos?

#

I did as it said in the example but I can't interact with it in game (the trigger, there is nothing to click on) and it only deactivates them, not activates them again when I click again

but are there any good pen systems working for udon?

somber nymph

#

I dont have UdonSharp installed ( the scripting thing with udon )

floral dove
#

The Jam is over but you are welcome to use all the assets!

burnt moth

#

but why doesnt qvpens work in my world, all I get is compile errors

floral dove
burnt moth
#

yeah I added the udonsharp but it didnt automatically ifx it

#

fix

floral dove
#

you'd need to fix any errors you have in your console. Since you're just getting started, I recommend you wait on integrating UdonSharp and use the official pens I linked to

burnt moth
#

can you send me the unity file, I don't want to ask for too much but that would be nice

thanks, how can I make an animaton play when I interact with a trigger

#

like making an npc speak when I click on him

floral dove
burnt moth
#

how do I create a data (node) in the graph

#

I can't find it

floral dove
#

what kind of data node?

burnt moth
#

the one in the example

#

I tried making a new node and searching for data but I cant find it

floral dove
#

that's not a data node, it's a Boolean[] node, and you probably don't need one, you'll just need a GameObject[] variable.

burnt moth
#

does this look good?

#

I tried my best and this is the outcome

#

I need the event thing still but dont really know where to put it

#

okay I added the interact event to the for arrow

floral dove
#

take a look at how the ToggleGameObject graph works. You want to do that, but for each GameObject in the array. If you're new to programming, arrays and for-loops take some getting used to. Maybe this will help your understanding: https://csharp.net-tutorials.com/collections/arrays/

burnt moth
#

also I know how to do CSharp but I really wanna learn graph and I find it complicated

warm goblet
#

what's the right way to get a reference to "Self" ?

#

Trying to do "GetComponent" and it needs "instance" and "type"

grand temple
#

if it's in graphs, you can just leave that empty and it will self references

#

this applies to udonbehaviours, gameobjects, and transforms

warm goblet
#

awesome, thank you thats what I needed

manic yarrow
#

What's the simplest way to disable a child object on pickup?

#

I was having issues with a udon graph earlier and the solution I tried didn't work

grand temple
#

have a public gameobject variable and then onpickup > gameobject setactive false. Ondrop > gameobject setactive true

manic yarrow
#

Let me show you the one I've already tried, maybe that one can be fixed instead

#

The intention is to make it so that if a pickup is held, the seat childed to the object can't be sat in

unknown.png
#

This didn't work, so I thought straight up disabling the object would work instead

#

It's to prevent people sitting while holding the object, which causes them to fly off

grand temple
#

yeah, disabling the gameobject would work as long as you don't have any meshes on it

#

you can just do vrcstation get gameobject

#

just in case, I would recommend doing onpickup > exit station and onenterstation > drop pickup

manic yarrow
#

Hmm, now that I think about it, it might be possible to do it another way and save on the number of graphs

#

Here's a graph that prevents the opposite, so you can't grab the parent while already sitting

unknown.png
#

would it be possible to add onto this instead?

#

that way it prevents sitting while grabbing in both directions with one graph

grand temple
#

yeah, you already have the pickup there

#

just add pickup drop

manic yarrow
#

Would that work? the script I just showed you is on the station while the previous one is on the pickup

grand temple
#

yeah, doesn't matter where you call it from

manic yarrow
#

How though? the pickup and the seat are 2 separate objects

grand temple
#

you already have the pickup from the getcomponentinparent

Okay So I am rlly new to SDK3 and I tried to Test my world to see if the mirror I did worked and then I got this message when i tried to export. So I am lost on how to do this...

#

hey i have a little question. how can I make a toggle for audio sources to switch them between 3d and 2D? (with Udon xD) i think with Spatial Blend but idk how qwq

manic yarrow
#

Unless all children of a pickup object count as picked up too

grand temple
#

no, not the ondrop event. I mean the drop function. You can tell the pickup to be dropped

manic yarrow
#

Oh, that's where I was getting confused

#

Where is that node?

grand temple
manic yarrow
#

wait, found it

grand temple
#

it's in the pickup folder, but if you're ever not sure where something is you can press tab to do a full search which will look in all folders

manic yarrow
#

Like this? Just want to be sure so I'm not making a build at putting my headset on for nothing

unknown.png
grand temple
#

yep

#

you may want to check if the player is local if you want other players to grab it

manic yarrow
#

With a branch I assume

grand temple
#

yeah

#

I think if someone leaves the instance without getting off, you may never receive the onstationexited so that would be another reason to only disable it for the local player

manic yarrow
#

Oh, nice

#

Between OnStationEntered and set pickupable?

grand temple
#

yes

manic yarrow
#

Both of them?

grand temple
#

yeah

manic yarrow
#

right, just making sure

grand temple
#

no, that's not how you use a branch

manic yarrow
#

Just noticed them isn't connected right

grand temple
#

the flow from onstationentered should go into the branch and then the true side should go into set pickupable

manic yarrow
#

See, this is why I keep checking with you 😅

grand temple
#

if it helps, you can consider the white lines (flow) moving forward, and then the variable lines (everything else) moves backward

manic yarrow
grand temple
#

you need to use the playerapi that you get from the onstationenter/exit

manic yarrow
#

same for exited I assume

grand temple
#

yeah but make sure the exit uses it's own

manic yarrow
#

oh?

grand temple
#

that's not going to be valid if your flow is going through onstationexit and trying to pull the playerapi from onstationenter

manic yarrow
grand temple
#

yeah that should work

warm goblet
#

Is there anything I can do to help with the jittering in vehicles for passenger seats?

#

all passengers have single frame pops every second or so behind the vehicle and then popping back to the seat view when we're moving fast

uncut tusk
#

i have it already tried

manic yarrow
#

If nobody touches the object or gets into the seat for 30 seconds, is it possible to make it respawn?

#

Someone told me I really need to add a way to respawn stuff and I figured that's a decent way to do it

uncut tusk
#

you could use a kind of timer trigger that says after the object has been released it respawns after 30 seconds.

manic yarrow
#

The tricky part would be making sure that both of the conditions are met, because someone might want to sit down or hold the thing for more than 30 seconds

uncut tusk
#

that could be solved with a variable that says that when the player sits down on the object or as long as he holds it in his hand, this timer is not executed

grand temple
#

sure, what you would do is have a private float representing the last time anybody touched it. Whenever you receive any exit events, you would set that float to time.timesincelevelload. When you receive an enter event, set the float to -1.

Then on update, just check if you're the owner (because you don't want everyone to try to respawn it), then check if it's not -1, then check if the current time.timesincelevelload is greater than the stored float + 30.

If it is, then set it's position, call flagdiscontinuity on the objectsync (so it doesn't lerp), and set the float to -1 just so it doesn't try respawning every frame.

manic yarrow
#

I assume lerping is when you see an object fly to its new location

#

in this context at least

grand temple
#

correct. For the person that sets the position, you'll always see it happen instantly. But anybody that is receiving the synced data will not know how fast it was moving so they will assume it's just a standard speed and make it fly into position. If you call flagdiscontinuity that says "make this object move instantly without lerping"

uncut tusk
#

I would maybe do that with object destroy. The corresponding object should then appear again at its place of origin if it is also set in VRCWorld so that the object should respawn if it has been destroyed or falls out of the map

grand temple
#

what no

#

absolutely not

#

destroy does not do what you think it does

manic yarrow
#

I assume the timer would be a network event delayed by (variable) seconds

grand temple
#

no, no network events

#

just the owner setting the position

manic yarrow
#

I mean for the timer

uncut tusk
grand temple
#

no, the timer is the float that is set to time.timesincelevelload

grand temple
manic yarrow
#

that's definitely what I want

#

there's no situation in which these objects need to respawn anywhere but where I placed them in Unity

grand temple
#

it's the same thing, but with setting the position you have more control and tbh less chance of breaking from future updates. Previous versions of vrchat had respawn get stuck on walls

manic yarrow
#

fair enough

grand temple
#

if you have a public udonbehaviour variable and you plug it into the sendcustomevent, then you are currently selecting an udonbehaviour with that graph and that graph has the public variable targetting a different udonbehaviour, it will automatically find all the events from that other behaviour and populate the dropdown

#

if you are doing something else like getcomponent, then it is not able to automatically find it. In that case, you can plug in a string constant instead.

manic yarrow
#

How would this timer handle multiple objects?

#

Let's say I have 6 of them on the map

grand temple
#

each udonbehaviour would be totally independent

manic yarrow
#

oh right, the timer is private

#

synced?

grand temple
#

no

#

there is no need since everyone is receiving the onenterstation event and the owner is the only one doing the respawn anyway

manic yarrow
#

What's the node for setting values to a specific number/
