udon-general

[spare kindle]

it instantiates the class that holds these variables

is that called when playmode is entered?

[tacit pasture]

Awake is yeah

[spare kindle]

oof

[tacit pasture]

its called once during the scripts runtime, so either in start or when it becomes active

[spare kindle]

its only called once ever?

[tacit pasture]

yes

[spare kindle]

ah okay, so that wont be affecting this

whatever ill just set them all as public

that fixed it

LMAO

god thats so scuffed

[desert grove]

private requires you to define the objects at Start. Awake is not supported.

[spare kindle]

if i modify the variables later in the script will that void them

on entering playmode

[desert grove]

if they are public. Cannot modify private variables.

[spare kindle]

im meaning within the script

[desert grove]

yes

[spare kindle]

so the only way to keep these modifications is to set the variables as public?

or am i missing something? sorry for the ignorance, never coded for unity

[desert grove]

if all your changes happen within the script you can modify the private variables at runtime. If you need to update them using another script they need to be public.

[fiery yoke]

You can. Just not really in U#

[spare kindle]

just to ensure all the info is out there:
right now i am assigning values to these private variables when you press a button in my custom inspector (in edit mode, not play mode)

when i enter playmode all of these private variables are voided

i dont want them to change at all on entering playmode

setting them to public seems to make my script* behave as I'm intending, but that kinda feels like a bandaid

[desert grove]

using global variables? I havent touched those in forever. Just gotten used to publics/serialized and linking scripts.

[fiery yoke]

@spare kindle what you need to do is add the [SerializeField] attribute to the variable

[tacit pasture]

any idea why a non master player cant set this?

are [UdonSynced] variables only editable by world masters?

[spare kindle]

gotcha, do i add [HideInInspector] too? the private variables are now showing up in my inspector when i use that

[tacit pasture]

thats the point of [SerializeField] variables

[spare kindle]

(im using DrawDefaultInspector();)

[fiery yoke]

uhh yeah I think so, depends what you want

[desert grove]

only the master OR owner of the object can update variables. So you need to assign the owner of the keypad before they set anything. Then it "should" update.

[tacit pasture]

ooo that could work

[fiery yoke]

only owner, master is irrelevant

[spare kindle]

ok great, that fixed it
thanks

[grand temple]

master is just the default owner

[tacit pasture]

gotcha, its only as i run 2 clients to test and the first one i enter on works whereas the second doesnt

but i think owner transfer is the fix here

[grand temple]

exactly, because the first is the master so they are also the owner

[tacit pasture]

yeah

i just hadnt considered this yet

[grand temple]

but as soon as it transfers to someone else, the master will be unable to change it

[tacit pasture]

finally go the networking side sorted i forgot about ownership

[tacit pasture]

i can just swap ownership on button press thats fine

[desert grove]

you'll need a proper ownership transfer. if is owner, else set owner.

[tacit pasture]

yup

[shy notch]

I have two different lights on my lantern, where am I supposed to put the event_start at?

[tacit pasture]

ive either done it wrong or it didnt work :(

 public void Save(VRCPlayerApi player)
    {
        Networking.SetOwner(player, this.gameObject);
        Password_OBJ.GetComponent<Password>().Keypad_Password = _input;
        _input = "";

    }

[shy notch]

I think I figured it out

[tacit pasture]

hoping this works

void TakeOwnership()
    {
        if (Networking.IsMaster)
        {
            if (!Networking.IsOwner(gameObject))
            {
                Networking.SetOwner(Networking.LocalPlayer, gameObject);
            }
        }
    }

    public void Save()
    {
        if (Networking.IsOwner(gameObject))
        {
            Password_OBJ.GetComponent<Password>().Keypad_Password = _input;
            _input = "";
        }
        else
        {
            TakeOwnership();
            Save();
        }
    }

[grand temple]

you're calling save inside of save?

also you're not able to take ownership if you're not the master

[tacit pasture]

if your not the owner then it will set as owner and recall

[grand temple]

right but if you're not the master, it will just cause an infinite loop of trying to take ownership and then doing save again

and you won't be able to take ownership so it will just keep trying to take ownership

[tacit pasture]

oh shit true

removed the master check

should be fine now

[grand temple]

the thing about udon is that it runs on the main thread with zero inherent delay. Which means that by looping like that, it's not just going to keep trying in the background over and over. If you tell it to do an infinite loop, it will keep calculating millions of times over and over and you will stop doing anything else, including rendering frames. You'll just freeze immediately

[tacit pasture]

now that sounds fun

[grand temple]

udon has a built in safeguard against this where if it detects an infinite loop happening for more than 10 seconds, it will forcibly crash the behaviour to stop it

[tacit pasture]

who needs crasher avatars

[tacit pasture]

okay well the ownership transfer didnt work

[grand temple]

what do you have now?

[tacit pasture]

it shouldnt matter that im using 2 clients launched from unity that are basically the same account right?

[grand temple]

yep that will work if the script is set up correctly

[tacit pasture]

aight well thats not the issue then

void TakeOwnership()
    {
        if (!Networking.IsOwner(gameObject))
        {
            Networking.SetOwner(Networking.LocalPlayer, gameObject);
        }
    }

    public void Save()
    {
        if (Networking.IsOwner(gameObject))
        {
            Password_OBJ.GetComponent<Password>().Keypad_Password = _input;
            _input = "";
        }
        else
        {
            TakeOwnership();
            Save();
        }
    }

doesnt change ownership

[grand temple]

yeah just get rid of this whole loop thing

[tacit pasture]

lmao

[grand temple]

??

[tacit pasture]

bruh no spamming

smh

[grand temple]

maybe it didn't like that it wasn't in a code block

    public void Save()
    {
            Networking.SetOwner(Networking.LocalPlayer, gameObject);
            Password_OBJ.GetComponent<Password>().Keypad_Password = _input;
            _input = "";
    }```

is _input a synced variable?

[tacit pasture]

no

[grand temple]

then why are you taking ownership at all?

[tacit pasture]

should i sync it?

[grand temple]

only if you need to

I have no idea what you're trying to do

[tacit pasture]

keypad_password is a synced variable from another gameobj

that syncs fine

the problem is when saving this variable

only the owner can save it currently

[grand temple]

if you want to modify that then you need to take ownership of that object, not this object

[tacit pasture]

gotcha

[tacit pasture]

its not worked

[pallid remnant]

how can i delay a command in seconds in udon?

i cant find a delay node

[grand temple]

SendCustomEventDelayed

[pallid remnant]

so you have to use customevent even though you might not need it?

[grand temple]

yes, it needs to know where to go to

[pallid remnant]

alrighty, thank you!

[tacit pasture]

for anyone who cares, only took 10 hours but its all working as intended now :)

[scarlet lake]

Hello there, does anyone know how I can add a video player or crayons when using the sdk3 for my world? I have tried using some from the booth and tried installing udon sharp, but the test along with build becomes inaccessible. Could they be outdated or am I doing something wrong? I am new to unity.

[floral dove]

the UdonExampleScene included with the SDK download has an example pen you can use

you can also find more extensive examples with how to use them in the info from our first jam: https://itch.io/jam/vrchat-sketchbook-jam

The example scene also has a video player, with info on how it works here: https://docs.vrchat.com/docs/udon-example-scene#udon-sync-player

[scarlet lake]

Awesome; ThankYou very much!

[stark adder]

Anyone figured out already why quest video player screen is white after migration from 2018 to 2019 ?

https://feedback.vrchat.com/sdk-bug-reports/p/quest-video-not-working

Turns out to be HTTP problem intentional ? That HTTP doesn't work on quest? Momo ?

[fresh lichen]

Anyone here experienced with Udon worlds that knows how to sync animations between players? Like syncing the startframe of an animation so that everybody in a lobby is on the same page?

[rapid echo]

If i make pickupable false on VRCpickup and the player drops the game object, does it fire onDrop() for that game object as well?

[vapid bough]

is there any udon scripts for a blacklisting or whitelisting system?

[desert grove]

in what context?

[cold raft]

probaly players, and while you can prevent them from entering the world, you teleport them to some corner of the map where they do no harm

[desert grove]

There are several prefabs for getting players names in the server, also Foorack has a keypad at this link as well that uses a whitelist. You can use either method for getting player names on player join and if their name is on the list teleport them. https://docs.google.com/spreadsheets/d/e/2PACX-1vTP-eIkYLZh7pDhpO-untxy1zbuoiqdzVP2z5-vg_9ijBW7k8ZC9VP6cVL-ct5yKrySPBPJ6V2ymlWS/pubhtml# Nothing on the community prefab list is specifically designed for this action tho.

There are situations where a whitelist will fail. Such as a player having special characters in their name.

[dapper lion]

who needed whitelist?

[desert grove]

Artorias

[dapper lion]

graph or usharp?

[acoustic delta]

Also this is a rabbit hole. First of all I think it's a gray-zone, if not directly against ToS, to do this kind of gating. Moderation should be up to the moderation team.

Secondly, if you are doing this to stop hackers/crashers then it will generally be futile, as those people can usually teleport to any player and prevent Udon from being executed locally.

[dapper lion]

whats goin on with your quest media?

[desert grove]

yep, probably best to wait on the Groups update for proper gating on a VRC level.

[tacit harness]

Hey question is there a way to check if there is a player in a specific area
I dont think i can use a collider to check cuz the player get teleported into the area

Is there a way ?

[stark adder]

Trigger area

[naive lagoon]

How do I fix this?
I've imported the latest version of UdonSharp and I'm still getting the errors.

[floral dove]

for UdonSharp-specific help, you can check out the UdonSharp GitHub and Discord

[naive lagoon]

There's a Discord server for it? Where do I find the link to it?

[floral dove]

we can't link it here but you can find the link through its wiki: https://github.com/MerlinVR/UdonSharp/wiki

[naive lagoon]

Thanks!

[tropic tangle]

Hey folks. I was just wondering how I could teleport an object?

[stone kelp]

Specific object or player?

@floral dove Are we allowed to hide Mature content behind a Udon protective script that forces so only verified users I approve are allowed to access that is in a public published world?

In my eyes that would be no different to having it as a private world, as only people I choose can access

[broken bear]

Whitelist programming is not a guarantee. malicious users may cause those protections to be bypassed and potentially enable that content for public joiners

[stone kelp]

Are modders / hackers able to activate / deactivate any gameobject because I can easily make 5 different checks on request

[broken bear]

I can only talk from experience (not nsfw stuff, just in-world moderation objects), things get enabled when they should not.

[stone kelp]

I've seen people being able to activate gameobjects that requires certain checks (Example is just to look at Jar's Murder game mode) to be made, but not bypassing a whitelist feature

[boreal kite]

anyone know if theres a way to get corrective shapekeys/blendshapes working? i hate weight painting

[floral dove]

🤷 I'm not a moderator

[fallow bronze]

can i play udon maps on quest?

[floral dove]

yes, if the world has been published for Quest

thx for the name change btw 😉

[fallow bronze]

np

i dont know why i had it as that

[floral dove]

haha no worries

[boreal kite]

can i drive a shapekey/blendshape by bone rotation useing udon

[tropic tangle]

Yes. Specific objects.

[stone kelp]

U# or Graph?

[tropic tangle]

Graph.

[stone kelp]

https://tenor.com/view/peace-out-im-out-bye-gif-14304356

[slim hound]

If it has ObjectSync there is a function for telling it to respawn

Otherwise you can just set its position directly through transform.position

[tropic tangle]

Okay. I'll try that. Thanks, Superbstringray!

[tropic tangle]

Thanks! Worked perfectly. 🙂

Is it possible to set a component as active or inactive in Udon?

[floral dove]

yes, you should be able to set .enabled for most components

[tropic tangle]

Thanks momo, I think I'm having trouble with the flow.
I shall look online. Don't want to bug you guys too much. 😛

Ugh. Yeah, having trouble figuring out how to referance the component.

Also, could I get a simple example of delays?
Like, a simple timer?

[toxic glen]

Hi all, not sure where to ask this, but I'm trying to figure out how to make a button that raises the player up. Notably like in Spirits of the Sea where the player can toggle to see over the pool table. From what I can gather, its almost like there's an invisible platform that the player stands on? Maybe I should code up a button press to spawn an invisible collider that pushes the player upwards? Would this be an option or would that cause some issues with clipping through it and etc.?

[desert grove]

yep, simple object toggle that reveals a platform typically local only. The vrcsdk example scene should have an object toggle in it.

a simple toggle would be ideally located outside the range of the hidden platform so the player presses it and then walks up to the area. However if you want to push the player up you will need to set the platform to be under the surface and move upwards. Adding a rigidbody set to kinetic to the platform will reduce the chance of the players avatar being slightly inside the platform.

[toxic glen]

Got it. Thanks

[desert grove]

hehe in addition your two movement options are a) animation b) transform position. option A is simple to setup, plenty of animation tutorials. Option B you can setup to change the height of the platform via a slider so even the tiniest players can see. With a slider you just set your height to be equal to the value of the slider without using whole numbers and set the min value to 0 and max to 1 which will force very small changes making the transition smoother.

[toxic glen]

hmmm. i see. i think an adjustable one with the slider would be best for a wide range of player sizes, so no matter what avatar someone is they can slide it to where they can see. So i would create a slider UI, and in my coding tell it what to do and tie that to a certain object to transform its position?

[desert grove]

Exactly. There are udon UI tutorials if needed on youtube, plus plenty of people here proficient in graph when the time comes.

[toxic glen]

Yeah, i can find a lot of tutorials on animating, but not the transform variant that I'd like to do. Might need help doing that haha.

[broken bear]

https://architechvr.booth.pm/items/2668806 check the ui slider here for an example on changing the float value by slider. You would use your Y transform animation.

[toxic glen]

I have no idea what I'm looking for in this ^ I have 0 experience with coding. This all looks like a foreign language to me.

[floral dove]

this page shows how to get a reference to any component: https://docs.vrchat.com/docs/udon-node-graph#drag-and-drop-for-gameobjects-and-components

[tropic tangle]

Thank you. I'll take a look. 🙂

[shy notch]

Is there a way to make an emissive effect only turn on when a spotlight is shining on the object?

I'm making a horror game that's disguised as a "sleep world" in VRChat. It's only a horror game if you wander away from the campsite. I want to make a bear that wanders around, and it'd be great if the eyes could glow when you shine your flashlight toward it. Anyone know how I could make that possible?

[tropic tangle]

@floral dove The 'Udon Node Graph' page specifically?

[floral dove]

The specific section to which I linked

[desert grove]

Yes, using Raycast https://docs.unity3d.com/ScriptReference/Physics.Raycast.html

[shy notch]

Thanks, you rock!

[tropic tangle]

@floral dove Alright, I'll read it shortly and take notes. Thank you.

[toxic glen]

Just wanted to let ya know i decided to make a stool item thats a local spawn instead of confusing myself to death.

[desert grove]

🙂 whatever works right? You'll get to more complex setups if you keep your development interest. No need to rush it.

[tropic tangle]

Is there a document with a rundown about every node? Thats more what I was looking for.

The link I was given, seems to just tell me the basics.

This is Space.Dot.Man btw. 😛 Just a different account.

[desert grove]

Just this https://docs.vrchat.com/docs/event-nodes
not even Unity has detailed breakdowns. Makes it hard starting out I suppose.

[tropic tangle]

Ah yes. I took a lot of that...

Wish there were examples for each type of node.

[floral dove]

Yeah - most of the nodes are just wrappers for Unity methods and properties, so you can look up the Unity docs for that. For VRC-specific nodes, you can check the docs linked to above, and/or open up "Assets/Udon/ReferenceDocs/index.html" in a web browser

We include examples for many of the typical nodes in the UdonExampleScene: https://docs.vrchat.com/docs/udon-example-scene

[tropic tangle]

@floral dove Thats perfect!

Thats what I thought. I'll have to look through the Unity stuff.

Yeah, I tried the example in Unity, but I honestly had no idea where to even start.

[floral dove]

I'd recommend you start by running a Build & Test on that scene to load it into the VRChat client, then go through each example where you can see the effects. Then return to the docs and read through the descriptions, poking through the graph to see how things are wired up.

[tropic tangle]

@floral dove Thank you. I will try that.

[tropic tangle]

Okay yeah. After playing the example, I just wanted to say that you guys did a great job. One could probably make a full game with everything you can do in it.

Quite impressive.

Excited to go through the different prefabs and figure out how to use some of this.

[tropic tangle]

A lot to unpack here.
Where is 'Get time' getting the 'time' from?
Is this what creates delay?

What does 'Single' mean in this case?

[grand temple]

time is the number of seconds since you launched the application

"Single" means "single precision float" which is just another way of saying "a number with decimal points"

[tropic tangle]

Okay,.Thanks, @grand temple.

[tropic tangle]

Managed to figure out how to set enable components and I'm having a blast.

Thing is, I'm trying to enable gravity on an object since, when its out of the world, it just falls and I figure thats not great on performance.

I (Mostly) got it working. But, the gravity seems to be moon-like. No gravity, even.

Figured out it just wasn't working after all. XD Not sure why I didn't figure that out.

Nevermind. I'm a dummy. Lol Got it working.

[shadow idol]

how i can *use the BetterPlayerAudio?

[tropic tangle]

^ Not sure if thats an Udon thing. 😛
But I'll do some research in the morning.

[winged estuary]

can someone help we were trying to initiate a vote kick against this toxic host and its saying unable to start a vote kick?

[tropic tangle]

You can't kick a host...Just make a new instance?

[winged estuary]

u used to be able to thats so dumb...

[lilac hatch]

eyop ; anyone could point me to a way to use trigger areas using either graph ? I'm finding a lot of stuff but everything seem to be "outdated" without any links / references to an updated version sadguh

( I guess it's the event OnTriggerEnter ? but I can't boot up vrchat to test right now )

[tacit harness]

You need a collider where the is trigger button is checked and then you can use OnTiggerEnter to get signal out of it

Also you said you cant boot vrchat just use cyanEmu and you can test everything in unity

[lilac hatch]

yush, did that right now

what I was looking for was OnPlayerTriggerEnter tho :) got it working perfectly now

Thanks !

[tacit harness]

Ah alrighty

got my shit working too now xD

[lilac hatch]

:D

[vapid bough]

My community was harassed for 2 and a half weeks straight with reports and proof to the dev team and nothing happened

[lilac hatch]

Black listing in a world is hardly doable because you can't just kick someone with udon itself I believe.

Best would be to turn on a gameobject that then teleport them away or something when their name is set but as Foorack said, the most annoying kind can just disable udon on their end or just world crash anyways.

Would be enough for the script kiddies I guess but eh

[dapper lion]

home portals are usually used to kick users

[scarlet lake]

I'm new to world development, how can I learn how to make things using Udon?
I'm working on my first proper Udon world and want to create things such as menus, teleportation based on standing on an object, and more things in the future

I don't really know where to start, I also have no experience in programming

I also want to look into NPCs and such in the future

[fiery yoke]

Udon creates a virtual environment that acts as a sandbox to run limited C# instructions in. Therefor I would advise to look at C# tutorials especially those specifically regarding Unity.

[scarlet lake]

Thank you ^^

[fiery yoke]

One important thing to note is that when you're working with the graph, almost every C# instructions will corespond to a node in the graph. You should probably look at the examples provided in the SDK first and foremost.

[cunning basin]

if you have no experience in programming, this is a pretty good place to start.....udon graph abstracts away the C# syntax so you can focus on your program/game logic

that being said...you still have to do a bit of reading (and experimenting) to get your money's worth

[scarlet lake]

Is there a way to debug and test udon graphs without building and testing and hoping for the best each time?

To see where errors might be

[mighty fjord]

Is there currently no way to find an inactive GameObject by name?

[cunning basin]

cyan emu

[dapper lion]

like: “case gameobject “A1” get!activestate”? (i can’t remember the exact way to type this out)

[mighty fjord]

I'm sorry, but I think you've lost me x)

Mostly wondering if there's any alternative to GameObject.Find(string name) that would let me get inactive GameObjects aswell

[dapper lion]

oh. well thats how i would go about getting specific objects

[slim hound]

Transform.Find can get disabled GameObjects but requires that it be a child of the GameObject you are searching from

[mighty fjord]

Yeah, that does mean I'd need the root object or something...

[broken bear]

Can you reparent the gameobject in runtime before disabled, assuming it’s enabled at start, just to sort it for searching later ?

[mighty fjord]

Cant reparent if I dont have it in the first place

If I did then I wouldn't need to find it anyways

[desert grove]

I know one of the search methods is not exposed, I'm pretty sure searching by layers is permitted. Either way, why not just define the game object in the script?

[grand temple]

Gameobject.Find does not require a root object

[mighty fjord]

Yeah, but GameObject.Find only yields active objects

Defining the GameObject in the script wouldn't be possible since I'm just trying to allow the user to search for a GameObject by a name at runtime, and it could've been instantiated by some other UB

Ultimately not a super important feature for this though

[grand temple]

so don't have it disabled by default

find it then disable it

[mighty fjord]

But since I'm not in control of it, I can't really do that, thanks anyways though

[unreal grail]

Can you get VRCPlayerApi from a raycast hit?

[grand temple]

no you cannot

but you can make a system that adds colliders to all the players and then if you raycast against that you can store whatever information you need on it, including the playerapi

[unreal grail]

Dangit all to heck. Okay.

[floral dove]

You can download the Udon Obstacle Course example scene and checkout the PlayerDataManager and PlayerData objects, which do this: https://docs.vrchat.com/docs/uoc-how-stuff-works#playerdatamanager

[unreal grail]

Oh, that's great

[spare parrot]

How can I have an animation constantly playing in my world?

[floral dove]

set the animation to loop

[spare parrot]

didnt work

[floral dove]

you can post in #world-development with some more details on what you're trying to do, this doesn't seem like it's related to Udon

[scarlet lake]

Does anyone know why activating my mirror also activates post processing and why post processing also actives the mirror ? qwq

[dapper lion]

you would need 2 interactibles which im not 100% sure if thats even possible

i would seperate the pp and mirror toggles into their own script

[lilac hatch]

some uh, stupid questions but ; Are synced variables synced with late joiners aswell ?

I believe it is the case but I am unsure so i'd rather ask.

[broken bear]

Yes, easily with manual synch and using it’s serialization methods

[floral dove]

As Fooma said. More info here: https://docs.vrchat.com/docs/udon-networking#bonus-concept-late-joiners

[lilac hatch]

Thanks a lot ! :)

[tropic tangle]

I udon capable of deleting or 'destory'-ing objects in game?

[lilac hatch]

UnityEngine.Object.Destroy seem to be exposed

so it should be doable using that I believe ?

[floral dove]

Note that Instantiating and Destroying local objects is fine, but not Networked Objects. For that, you want to use an Object Pool.

[lilac hatch]

Using Networking.Destroy isn't doable in this case ? I see it there aswell

Sorry for the questions, just trying to understand how it work correctly since i'll surely have to use it soon enough

[tropic tangle]

Thank you guys. Really big on saving processing power or whatever the term is.

[tropic tangle]

Does that mean if I have an 'Object sync' component, I won't be able to destroy within the game?

[floral dove]

You can destroy it, but its destruction may not be synchronized (not sure), and you will not be able to recreate it

that's why we built the Object Pool: https://docs.vrchat.com/docs/network-components#vrc-object-pool

[tropic tangle]

@floral dove okay thanks. I'll check it out.

How do I reference a object from a vector3 output?

Trying to make the value a prefab that I intend to reuse.

[floral dove]

not sure I understand but - if you're creating a Vector3 somewhere in your graph, then you want to reuse that value, then you want to use a "Set Variable" node to set it, and then a "Get Variable" node to get it.

[verbal socket]

i have a weird question

is it possible to have an item that when you hold it

you fall slower ?

think like marry poppins / slow falling in minecraft

but with a mushroom umbrella

[floral dove]

sure - check out https://docs.vrchat.com/docs/player-forces#getgravitystrength--setgravitystrength

[scarlet lake]

I'm trying to use Udon Sharp to make it so that when my player collides with a certain collider it will teleport me to another location on the map and I can't figure out what terms I should be using
Does anyone know?

[grand temple]

it doesn't tell you what object it collides with because you already know that it's colliding with the object the script is running on

also onplayercolliderenter is probably not what you want. That's for when a collider physically moves and touches a player.

If you want to detect when a player walks into a trigger volume, set the collider to istrigger and use onplayertriggerenter

also you'll need to check if player.islocal because onplayertriggerenter will happen when anybody touches it

[scarlet lake]

Thank you ^o^

[quick basin]

anyone know what this error is?

[grand temple]

that error can happen if you have folders with spaces

[quick basin]

spaces?

[grand temple]

/my cinema/ has a space

change that to something like my_cinema or my-cinema

[quick basin]

oh ive uploaded it like that before but iwill try that

[quick basin]

hi its still happening

[grand temple]

and what's the error now?

[quick basin]

sill the same error

just renamed

[grand temple]

that clearly still has a space

[quick basin]

this is gonna sound VERY dumb but how do i rename it..

[grand temple]

I think this should do it https://support.unity.com/hc/en-us/articles/115000086383-How-do-I-change-my-Project-s-name-

actually no that's not the problem. I've definitely had projects with spaces

it's some specific folder, I'm not sure exactly

[quick basin]

oh damn i have loads of folders lol

[trim sapphire]

Is there any way to get the subdirectories of a directory within the project folder at runtime? In native Unity, it looks like this can be done using System.IO.DirectoryInfo, but this doesn't get exposed in Udon. Here's what I was trying to do:

System.IO.DirectoryInfo metadata = new System.IO.DirectoryInfo("Assets/Metadata");
foreach (System.IO.DirectoryInfo folder in metadata.GetDirectories())
{
    Debug.Log(folder.Name);
}

If I can't get information about directories & their contents at runtime, is it possible for me to load assets from file if I somehow already know their path relative to the Assets folder?

[trim sapphire]

Yeah, it doesn't seem like Udon has access to Resources.Load, either. I'm trying to load plain-text XML files. Maybe I'm misremembering, but I think people have loaded assets from files in Udon before. Is there some other way to do it?

[scarlet lake]

When using the unity udon video player; I've set a YouTube link in but it won't autoplay the video when I start the test. Is there a way to fix it so I don't have to type it in every time? The Autoplay is checked too.

[plain night]

@scarlet lake There is a sync box option that has to checked marked. Im not a unity expert but we ran into a similar problem, and checking that option helped out a little.

this is my current problem...any help would be nice. this is for the wolf video player

@ me if possible

please and thank you.

[plain night]

@scarlet lake https://www.youtube.com/watch?v=CQdjyHFxwK4 Hope this helps.

[fiery yoke]

You need a TextAsset variable. You can then read its text content with the .text getter

[lusty elk]

i'm having a problem teleporting players to assigned teleports
I have a button that on interact gets the API's of all the players in the room (up to 6 for this case) and then goes through a for loop that should teleport player[i] to their proper teleport spot, but it only teleports the local player instead of everyone

its only teleporting player[0] but not player[1-5]

[fiery yoke]

For some reason (good or bad) VRChat disallows teleporting remote clients. You instead either have to run the same logic individually on every client, or send every client a message to teleport themselves somehow. That second options only works in specific scenarios, and the first method is hard to get right in certain other scenarios.

[lusty elk]

ah, got it, thank you!

[trim sapphire]

Thanks for the response! Follow-up question: Is it at all possible to load the TextAsset from a file path (within the project folder) at runtime as opposed to setting it as a public variable on the Udon Behaviour? I may be handling hundreds of XML files, so I'm not sure if it's feasible to give them each their own variable.

[fiery yoke]

Only assets that are actually referenced somewhere in the scene are uploaded to VRChat. So no they have to be referenced before hand. You can put them in a large array by hand or using an editor script tho.

[trim sapphire]

Ah, gotcha. Thanks!

[tropic tangle]

Starting to get the hang of this, I think. Managed to get a cube to rotate towards the player.

Now how do I set it to move forward with transform?

I prefer not to use the physics engine for this as, I imagine its more intensive.

[hushed gazelle]

Is there no way to set the startColour of a Particle Emitter with a Colour rather than a MinMaxGradient?

[cunning basin]

is there already a way to have multiple udon tabs open?

[scarlet lake]

I'm still trying to create a teleportation system based on collision with a box collider, haven't got anything working so far

Oh

Crap

I just realised I used collision enter instead of trigger enter

But does anyone know what the compiler error is ?

[stray junco]

hi

is this combat system compatible with current udon world sdk?
because when i import it to my project folder
it show's a bounch of console errors

idk if this is because i have many assets in my project folder or it's simple a problem with my sdk and i need to reimport it
or it's actually problem with this asset

here:
https://github.com/Toly65/UdonCombatSystem

any idea what colud be?
please help me

[floral dove]

every GitHub repo has a place to file issues to the author, try reporting your issue there: https://github.com/Toly65/UdonCombatSystem/issues

[floral dove]

sorry, the Window system that the Udon Graph uses only allows for one graph at a time right now. What is it that you'd like to do with two graphs open?

[floral dove]

the issue is that you're calling base.OnPlayerCollisionEnter, which is a Base type. You can remove that call.

[scarlet lake]

Thankies ^^

[cunning basin]

i just want to have more than one open

[stray junco]

@floral dove
so there is no any vrchat support for combat system
like download already made asset made by vrcdevs
because i just can make it in udon
i dont understand coding😢

at least it will be nice that someone can show in his video tutorial
how to connect weapon to something in udon idk what a hell it is

[floral dove]

but why? If you can explain what is enabled by having two windows open, we'll understand how important the feature might be

[floral dove]

we don't offer support for the specific combat system that this random person made, no

[stray junco]

great thanks
now i can happily suffer 🙃

[desert grove]

For me it is efficiency. Having all my script tabs up is faster than navigating to a script and opening it when needed. It is also beneficial when learning because you can compare your script(graph) to a working one instead of copy and paste. But I use U# so I have the benefit of Visual Studios supporting multi tab and multi window display.

[cunning basin]

basically what kev said....i'm not too worried about it tho it would be a nice to have -- i'll dip into U# when i feel it will be more efficient but i think the meta would be to code everything you can w the visual graph before getting into the weeds w rider or vstudio

[silent mortar]

Can anyone verify this bug? UtcNow on quest headsets is 1 hour slow. On PC it works as expected and gives the proper utc time.

[desert grove]

Try #quest-general as this isnt related to vrc. Google results suggest factory reset btw.

[silent mortar]

im referring to the udon node getting utcnow

on pc it returns the "correct" utc, but quest users in my world report the time is 1 hour off.

however, get "now" works fine. I need both to calculate the proper timezone offset to apply to a series of dates to convert to a user's "local" time. I'm making a schedule.

[tacit gust]

Hey! I cant seem to get video players to work correctly. Is this the right place to ask?

[floral dove]

have you verified this issue on a Quest headset yourself? Just need to make sure it's not an issue with the user's clocks

[silent mortar]

I don't have a quest headset myself, but i've asked several users

[floral dove]

Have you tried the Example Video Player in the UdonExampleScene?
https://docs.vrchat.com/docs/udon-example-scene#udon-sync-player

[floral dove]

sounds like a good candidate for Canny if you'd like to verify whether it's an issue

[silent mortar]

does it go under udon alpha or quest creators?

[floral dove]

If it's an issue specifically with Udon worlds, then Udon Alpha.

[tacit gust]

I meant ingame, Im just a player.

[floral dove]

this channel is for discussion of Udon, you can visit the #faq to learn where to ask other questions

[tropic tangle]

hey folks. Still trying to figure out how to get an object to approach the player api.
Which node in the 'transform' is the best for that? I tried 'Set Forward' but that only seems to rotate the object when the player moves.

[floral dove]

have you looked at the "FollowPlayer" program included in the UdonExampleScene? It lerps towards the player with adjustable smoothing: https://docs.vrchat.com/docs/udon-example-scene#choosercontainer-1

[tropic tangle]

@floral dove oh cool! I'll check that out.

[floral dove]

the program negates the YOffset in order to stay on the ground but that's easily modified

[tropic tangle]

Didn't know that was there. Thanks. 🙂

[floral dove]

Sure thing! Since you're just getting started with Udon and looking to learn what's possible, I highly recommend you go through all the examples in that Scene and the associated online document.

[wintry radish]

Hey peoples. I have an issue where I create an array via the CreateInstance node and save it to a variable and I can read the length of it just fine right after I created it, but apparently if I access the GetLength node later (for example with a button press) it returns null.
Am I forgetting something or what's happening there?

[grand temple]

don't use CreateInstance, use constructor

[wintry radish]

Where would that be? I'm using udon graphs btw

[grand temple]

go into the array type's folder like float[], then search for constructor

or if you're ever not sure what folder something is in, you can always press tab to do a full search

[wintry radish]

And why is CreateInstance bad? Just asking so I understand it

[grand temple]

it's probably something automatically generated that is never meant to be used

[fiery yoke]

CreateInstance is a static method of System.Array that creates an array of a given type with a given length. In theory that should work just the same. But I would also advise to use the constructor instead...

[wintry radish]

Well @grand temple and @fiery yoke thanks for that tip, but that sadly didn't solve my problem

[fiery yoke]

Then youre doing something wrong :P

[grand temple]

could you share your code?

[wintry radish]

Oof ehm. Give me a sec

The second Log in the bottom right returns Null (triggered by the Interact Event)

[grand temple]

huh? I'm pretty sure ints cannot be null

or do you mean the behaviour crashes because the array is null?

[wintry radish]

No it just returns Null

[grand temple]

can you show the logs?

[grand temple]

whaaat

have you clicked the manual recompile button after changing to constructor?

[wintry radish]

Yeah I did

That's the reason why I'm so confused. I have been struggling with this for a few weeks now and can't figure it out

[grand temple]

ohhh it's because you combined multiple flows together

don't do this

it's not that the value is null, it's that combining flow together screws up the graph and it doesn't know where to pull from anymore

use a block node instead to do one thing, then do another thing afterwards

or make an event and then sendcustomevent

[wintry radish]

That could be it... and kinda makes sense, but why do they allow it if it causes issues?

So you mean if I wanna put a flow together again I should rather use a custom event on both things?

[grand temple]

Yes

Or avoid the situation in the first place by using a block

[wintry radish]

But a block only splits flows... How would I put them together with a block again?

Or did I misunderstand that?

[grand temple]

I mean split it before you do the isvalid

[wintry radish]

Okay that could also work

Also... It works :p

Thanks ^^

[pallid mango]

It can be done in most cases but it has side effects that you need to keep in mind

It’s analogous to goto command. Useful in the right hands messy in the wrong hands

[wintry radish]

Okay understood. I'll try to use it less ^^

Also now I have another issue xD
If the cube gets destroyed by anything other than the button press the array apparently breaks and the behavior gets halted before it even checks if it's valid.
So the graph breaks at the Is Valid Node and Idk how to do it different

[pallid remnant]

hey guys i'm trying to add a volume slider to an audio source and i just cannot get it to work

it works in the unity editor but stops working in the vrc client

using cyanemu to test

the little blue ui interaction lightray does not show up

[grand temple]

setting an audio source volume is probably one of the many events that gets removed from unity events

this is for security reasons

instead you can send a custom event to an udonbehaviour, then the udonbehaviour can be set up to read the value of the slider and set the volume of the audio source

[pallid remnant]

i parented it to the same canvas as the url input of the video player i'm trying to change the volume of

[pallid remnant]

i think thats what i'm doing

[grand temple]

can you share a picture of the slider?

[pallid remnant]

the code

slider

i have it set to the default layer so it should be able to collide with the player

and i added a ui shape but that didn't help eather

either

[grand temple]

are you unable to move the slider? Or does the slider move but do nothing?

[pallid remnant]

unable to move it

[pallid remnant]

it does work in the unity editor

maybe my canvas is not large enough?

[night viper]

Doesnt the UI shape needs to be where the canvas component is? or can it be anywhere?

[pallid remnant]

i think so its on the canvas by default but because i couldnt touch the slider i thought maybe it needed one too

[grand temple]

no, just on the canvas

also make sure it's not on the UI layer

default is fine

[pallid remnant]

okay it was the canvas

it covered only the url input, not the slider

thats why i couldnt collide with it

thanks guys

[grand temple]

ah that would do it too

[scarlet lake]

How can I make it so that on line 15 it teleports me to GameObject AvatarTPEnd?

[floral dove]

_PlayerLocal.TeleportTo(AvatarTPEnd.transform.position, AvatarTPEnd.transform.rotation)

it may help to learn the basics of Unity GameObjects and Transforms: https://docs.unity3d.com/2019.4/Documentation/ScriptReference/Transform.html

[scarlet lake]

Thank you QwQ

I will make sure to read that

[scarlet lake]

Is there a way for me to change that big green collider at the top of my screen position and scale?
I made custom avatar pedestals

[fading cipher]

Since Unity has a limit of 32 voices playing at once, does a player's VOIP count as one of these voices?

If my world is expected to host a hard limit of 16 players does that mean I would only want to play up to 16 other sounds at once?

[tropic tangle]

Just wanted to say, @floral dove thank you for the information! I managed to get an enemy to follow the player. 🙂

I actually surprised myself with how easy it was to read, understand, and put into practice.

All hail the vrc dev team!

[tropic tangle]

I have more of a programming question if its okay.

I was wondering if there's a way to determine when an object reaches from A to B with LERP.

I want to make a path finding system, and I'm starting with creating a patrol behavior.

Now, I know what you're going to say, 'Why don't you just use NavMesh' ?

Well, its my understanding that using Nav mesh is more intensive on cpu, and I want to develop for quest as well as pc. Every quest compatible world I've played that uses a nav mesh system for npc's or enemies seem to run poorly (Could be just because I'm a Quest 1 User, but even so. :P).

So, I want to make node objects that the enemy object takes information from to figure out path finding.

I believe its called A * pathfinding.

Sorry, I know its a big question. I'm just wondering if there are any alternatives to using Nav mesh in Udon and if there are any resources for me figure out how to get started.

[cinder marten]

I'd like some assistance if possible

Trying to learn some Udon stuff and I currently have a premade Udon script that lets me turn items into buttons to toggle things on and off
but I want to make it so say
if someone has the HD mirror turned on, when they turn on the other mirror, it will disable the HD Mirror

[floral dove]

FYI Udon is slow when compared to C# or native code due to the way it sandboxes things for security. So NavMesh is likely to be much more performant than anything you can make directly in Udon.

[floral dove]

for your basic question, though, you can compare two floats, and check whether the difference is below a given threshold in order to determine when you're nearly at the end of a lerp

[tropic tangle]

I'm embarrassed that I didn't think of that. Bahahaha. Thanks, Momo!

[floral dove]

sure thing! Here's the approach in c#: https://csharp.2000things.com/2011/09/21/416-use-an-epsilon-to-compare-two-floating-point-numbers/

it's a good way to go since floating point numbers can be almost-but-not-quite equal (like 1.0000001 vs 1.0000002 are not equal but probably close enough)

[tropic tangle]

Yeah, it would probably hard to have transitions work if the npc is having a hard time getting to the exact point. Am I understanding that correctly?

[tropic tangle]

Can you elaborate a bit? I might be able to help.

[tropic tangle]

Oh wait, I think I understand. One sec.

[tropic tangle]

I would use a booleon and a branch. Otherwise known as a 'If' statement.
I'll see if I can make a screenie a for you.

[tropic tangle]

Pardon me, as I'm relatively new. But I could probably cook something up.

[grand temple]

There's no need to do any branching, you can just make it so the LQ mirror button always disables the HQ mirror. Just add a new gameobject target and setactive false

[hushed timber]

im confused what exactly is udon

[grand temple]

?whatisudon

[hidden marten]

VRChat Udon is a programming language built by the VRChat Development Team for use in VRChat worlds! It enables complex behaviors and logic in VRChat worlds. Read more about Udon in our documentation: https://docs.vrchat.com/docs/what-is-udon

[hushed timber]

oh nice. thank you

[toxic glen]

I thought Udon was a type of noodle Kappa

[fiery yoke]

It's called Udon because the connections between nodes in the graph used to look like Udon noodles. However the design changed slightly due to the upgrade to a newer graph framework in Unity.

[plush stump]

How to create an object that inside the player avatar and follow his movement?

[scarlet lake]

Why did the invisible man turn down the job offer?
He couldn’t see himself doing it.

[narrow stratus]

here's the trigger

and the teleport

do i have to make another variable for the private string in the trigger to get the "enable" part to work?

actually i figured it out

i add a variable of a string and name it enable

i guess that's how it works?

[hushed gazelle]

Is there a reliable way to identify how tall a player's avatar is?

[tacit harness]

Hey so i made a skybox change in my world but i have noticed it dosent change the light color to the one that normally gets generated by the skybox how can i change it so it changes properly with the skybox

Pls dm me or ping me if you know how to fix it (https://i.imgur.com/sXhSi0k.png how i currently have it)

[scarlet lake]

Is it possible to make something toggle on or off if a player respawns manually?

[unreal grail]

I am trying to create a camera that takes "photos" by turning a render texture on and off. It is not seeming to work. Any suggestions?

[dapper lion]

have you tried turning off the camera instead?

[unreal grail]

Yes, that is what I meant.

I turn the camera on, I get the target player's tracking data, I move a camera to their head location + an offset, I have the camera LookAt the player's head, and then I turn the camera off

[dapper lion]

ok that sounds overcomplicated. what are you trying to do exactly?

[unreal grail]

Take a 'photo' of a player, no matter where they are in the world.

[dapper lion]

ok so you can do the tracking data on a parent of the camera. and disable only the cam

[unreal grail]

So I have to get the player's location data, then have the camera look at them, then turn the camera off to take the photo

Yes, that's the idea.

This is what I have in U#, but it's not working. https://pastebin.com/MQK8vXXq

The camera is offset from the parent's position

[dapper lion]

so whats breaking/misbehave?

[unreal grail]

It doesn't do anything when activated.

TakePhoto is called, but it doesn't do anything.

[dapper lion]

what is your void/trigger method?

i dont see any in the pastebin

oh wait. this is it

so youre doing all of this in one event?

[plush stump]

May I ask why the first method(above) works and the second method(below) didn't? both use interact as trigger. It seems that the object spawn by the second method is auto-disabled.

[slim hound]

Objects assigned in an object pool get automatically disabled at runtime and need to be enabled/spawned with VRCObjectPool.TryToSpawn

Also instantiate creates a new non-networked game object and likely isn't what you want to be using

[slim hound]

You are enabling and disabling the camera component in the same update so the camera will never render

Instead of enabling and disabling it use Camera.Render

[plush stump]

Thanks

Is there a function to add or remove elements from array?

[slim hound]

for the object pool you start with a set amount of objects in the pool that you can access

[fiery yoke]

Arrays are fixed-length. They have "slots" that can hold a value.

[indigo finch]

Hi, I'm having a little problem... any idea why I can't disable station exit? Is this the correct way of steal controls for a car?

whenever I run it deselects again...

[slim hound]

Station components will always reset to their prefabbed values

You will need to unpack it so its not a prefab

[indigo finch]

aah... never would have found that. Thanks!

[fiery yoke]

Im pretty sure that that is not the case and not the problem.
The value isnt properly saved, because it isnt marked as "dirty". Set the boolean, then change something else in the scene like the name of a gameobject or something then save.

[unreal grail]

You are a hero

[autumn birch]

Anyone have an udon script to disable an object at the end of an animation or at a specific time in the scene? Specifically a camera.

[tropic tangle]

Hey, folks! I have another udon/programming question if it's alright.

So, in my world, I plan to have flash lights.

Problem with that, is real time lighting is super intensive.

So, I was wondering if there was a way to implement lighting with, perhaps an object (a plane, maybe) that's just a transparent image texture with a bright color.

Would that be possible with some sort of ray-majjibby (can't remember the name right now.).

What are some ways lighting can be impliment without making my quest get slow? :P

[floral dove]

yes, an interesting problem, and appreciate that you're building with Quest users in mind! One thing to try first is whether Quest can decently handle a single realtime light - in which case you can make only the local player's flashlight actually work to limit things to one realtime light, and turn off realtime shadows.

[dapper lion]

could use a projector for the light or if you must use a realtime light, set it to the layer that your meshes are set to and nothing else

[floral dove]

you can use a particle material with additive blending, which will make things lighter but it won't look like real lighting. Another way I could think of would be to Raycast from the flashlight to objects, and either change the tint of an object when the flashlight is pointing at it, or swap its material.

[dapper lion]

so for example, you have a wall on the reserved4 layer. tell the light to only cull on the reserved4 layer (and dont do shadows like momo said)

[floral dove]

it would feel more like highlighting / selecting objects than lighting them since it would be constrained to their mesh

[tropic tangle]

I considered making the lighting local. But, my issue with that is that I want the players to be able to use light to help each other.

I'm using Udon to make a prototype of a horror game with some basic combat and such. Think no-budget silent hill.

Anyway, I think it would be cool if players can use the flash light to point out various things to each other.

[worn moss]

Slowly learning Udon toggles and was wondering if anyone can direct me to how to make toggles to turn on 1 gameobject but then turn off multiple gameobjects, all within the same toggle.

[tropic tangle]

Ooo thanks! That's a great idea!

[tropic tangle]

That's a great idea too! Was planning to use culling extensively for the project. So that may work too.

[tropic tangle]

I actually came up with a similar idea once. But I didn't think to use a particle system.

Is it possible to use raytracing to change the size of an object based on how close it is to an object (a wall for example)?

Because that raises another problem : the light on the flashlight might go through walls.

[dapper lion]

i can’t remember if projectors go thru walls but could try projector

[tropic tangle]

I'll have to look up projector. Not too familiar.

[scarlet lake]

how do I make a teleport?

[tropic tangle]

Use the 'set position' node and make sure the instance is the player API.

Oh and make sure it's not public.

I would make you a screenie but I'm headed to work and not neat a computer.

[scarlet lake]

idk how udon works lol its my 1st time

[fiery yoke]

The way you solve this is by first toggling all objects off, and then only toggling the object you want on.

[scarlet lake]

nvm smith got my back

[tropic tangle]

For what I want to do, would it be wise to seperate all environmental meshes, and apply occlusion culling to them all individually?

Or, are there potential issues with that?

[dapper lion]

occlussion culling is usually a good way to save performance

[tropic tangle]

Yes. That's correct.

I'm asking, is it wise to seperate my world mesh in blender, so that as seperate objects, they can be culled out more seamlessly (I assume objects as individuals get culled out, not so much the parts of the mesh.)

Might also culling things out manually myself with the flashlight. But it might not be necessary.

[dapper lion]

ye. that would work

[neat flicker]

If I were to make a sliding door (a door that a player must physically grab to slide open) would it utilize animations?

[fiery yoke]

Probably not. But instead I would use Maths :P

[neat flicker]

This is part of Udon or Unity? (Sorry, still new to Udon)

[fiery yoke]

Math is part of reality.
In particular Vector Math and Linear Algebra. Those sound like big words, but the basics are realtively simple, and unfortunately if you actually want to make your own systems, you will need to know at least the basics of those things.

[neat flicker]

Thanks! I'll get to researching!

[fiery yoke]

https://www.youtube.com/watch?v=MOYiVLEnhrw I can personally recommend this Channel. Its a 3 hour video, but its very in depth and will give you a lot of insight into whats important in Linear Algebra for game developers.

[autumn birch]

Having some real issues with post processing in the new version...
When attempting to upload my world VRCSDK and VRCSDKCAM remove my post processing camera effects... toggling those on/off proves that... Why is VRchat removing my post processing?

and it also properly displays post processing when just hitting play instead of uploading. So it's specifically the VRSDK that's removing my post processing since that is added after hitting build & publish for windows.

anyone know why?

[broken bear]

It will remove it for quest, is it doing it on pc?

[autumn birch]

PC

I've tried everything now.. making the depth different, every setting in a camera that could be tinkered with to fix the issue has been tinkered with >_>

[dapper lion]

make sure the post processing is set in the post process layer

[autumn birch]

I was told to put it in the water layer.

Is a post processing layer something new?

[dapper lion]

thats a new one. thats usually for cameras and recording data im pretty sure

[dapper lion]

no. its a been a thing forever for vrcsdk

[autumn birch]

also there is no post processing layer

[dapper lion]

do you have only 8 layers?

[autumn birch]

14, 3 reserve layers

[dapper lion]

one of them should be labeled post process or something close

[autumn birch]

Nope, but I just made one and attempted to upload, crashed unity XD

[dapper lion]

that was most likely unity being unity unless you did something weird after

[autumn birch]

nope, swaped layers to post processing and hit build & publish'

[dapper lion]

hmm ok well

https://github.com/oneVR/VRWorldToolkit/releases this comes with a post processing set up

[autumn birch]

will try

[foggy knoll]

So I uploaded my first 3.0 avatar this week. I've been used to doing stuff in 2.0, so I kinda feel like I'm relearning the whole process again, Anyways I use FBT and I have noticed that my view point drops below my neck when I sit down. So the only thing I can see is the inside of my chocker. How do I fix this?

[fiery yoke]

How about you ask that in #avatar-help and not #udon-general ? :P

[foggy knoll]

Sorry I

ill ask there.

[fiery yoke]

Just people with more experience with avatars in those channels than here.

[quick basin]

what would the graph be to change url of video player from UI button i have this so far

[floral dove]

there's a fully working example of a Synced Video Player included in the SDK, with documentation here: https://docs.vrchat.com/docs/udon-video-sync-player

That's a VRChat Team member lmao

oop

he got beaned lmao

[quick basin]

so this is the graph i need?

[floral dove]

that's the part that has the player become the owner of the video player and update the URL, yes. You should be able to hook that up to a UI button with a baked-in URL with a few changes - have the UI Button fire the "OnURLChanged" event, but you can get the VRCUrl from that variable you've already got instead of getting it from the VRCUrlInputField

[tawny sapphire]

Hi guys, I'm new to VRC and would like to start learning Udon graphs. Is there a central documentation of all the API/Nodes and descriptions of what they do? I am looking to search through it and read off them in list fashion if possible. Thank you very much.

[floral dove]

I've got a pinned message with a suggested docs reading guide for getting started with Udon: #udon-general message

Most of the nodes are wrappers for Unity classes, methods and properties so there would be thousands of them to read through, but you can find info on those in Unity's docs.

[tawny sapphire]

I see, I will follow these guides then. I also watched all your videos and they are a good start as well. Thank you very much!

[bright onyx]

I assume 2019 unity requires we make udon worlds instead of using the 2.0 sdk?

[grand temple]

Nope, you can still use sdk2

Just make sure to get the latest version of the SDK

[bright onyx]

ah okay

I keep having errors saying that there are broken scripts but nothing is showing that there is a certain script broken and i can go into play mode just fine. it forces me to reolaod the scene and then doesnt upload. so i thought maybe it was an sdk issue

[grand temple]

Can you show your error console?

[rapid vale]

i am having similar issues with the new sdk

was fine until i updated to latest

removed and installed latest cleanly but still vrc tab wont show up or anything

for sdk2

[grand temple]

did you upgrade straight from unity 2017 to 2019?

[rapid vale]

nopee its 2018

[grand temple]

the latest SDK is probably not compatible with unity 2018

you should use unity 2019.4.29f1

and you also need to follow the migration guide

[rapid vale]

ohhhh okk

yeah i was following it and it said to add the 2019 sdk before migrating

i was like dam i broke it lool ok lemme import project to 2019 then seee if it works

thx

[indigo finch]

Here's one I made when I was starting out that does just that. Check over it and see how ya go. It does however require there to always be at least one thing being selected and deselected, though back then if I didn't want one of those fields I would just toggle an empty gameobject. Nowadays, I would add an if statement to check if an array was empty (array.length == 0), but for simplicity's sake, I didn't add that in here

[onyx owl]

Definitely not an Udon question, but yall are smart..
I'm writing a script for a prefab im building

In the standard 3.0 descriptor, when you edit your viewpoint, a PositionHandle is drawn and you are able to move around your viewpoint without actually having any gameobject selected.

I'm looking through their editor code now, but preemptively does anyone know how to recreate this?

[plush stump]

can you interact with a button whose owner is set to someone else?

[grand temple]

sure, ownership only determines who can set the synced variables. It does not prevent the interact event from happening

but of course if you want to lock something to just the owner, you could check if the localplayer is owner after the interact

[plush stump]

thanks.

anyone use setplayertag and getplayertag to assign roles? Shall I create my own variable to store roles or shall I just use the tag system?

[grand temple]

tags are useful if you have some udonbehaviours that need to access the values from anywhere and you don't want to bother with giving those udonbehaviours a reference to some central object that stores the value

it also might be useful if you're not familiar with working with arrays

but tags aren't really magical, they don't sync, they're just a place to store some values

if you want to sync roles you could actually use the obstacle jam's starter kit. That comes with a system that distributes a unique object to each player, and you can put synced variables on those

[plush stump]

I prefer using arrays but I only knows how to store roles based on playerID, which is a string and that don't sync

I'm thinking about using Array like [PlayerNum, PlayerID, Role, Cooldown, etc] to store all information about the player

[grand temple]

yeah, you could totally do that. Players wouldn't be able to own their own information though, they would have to communicate with the master and the master would sync the array

There's nothing wrong with that, if anything it would be more secure. But it would have more latency

[plush stump]

I get stuck at how to get to the correct array for my player.

if PlayerA is interacting with the button, how should it communicate with the master to get PlayerA's role? My plan is to give each player a numberb between 1-40 based on their IDs, so it can direct to the right array when the program get their ID.

[grand temple]

You don't have to communicate with the master to get anything if the master is already syncing the array whenever it changes. Just access the array

[plush stump]

Will string store in the array sync as well?

[grand temple]

Yes

[thorny silo]

why does my vrchat client not open up when trying to build and test my udon world?

[indigo finch]

thats... strange. As a sanity check, you can start vrchat normally (aka via steam) right? Also, how old is the sdk your using? consider updating it to the latest if it's not currently

[thorny silo]

I just got the newest sdk

Sorry I'm like extremely new to udon, I just placed the VRCWorld within the model and pressed build and test

these are the errors i'm getting

[indigo finch]

the fix is rather dumb

you cant have an apostrophe in the file name. its a unity thing

[thorny silo]

oh

So just rename the folder?

[indigo finch]

yup. should work. the error is saying it cant find the file, and ive had the same problem with naming

[thorny silo]

it didn't work, but i'm gonna try transferring the unity package with everything in it to another file

[indigo finch]

ah, okay. yea... unity can be a pain sometimes. let me know if that doesn't work

[thorny silo]

will do

[viscid reef]

it looks like you had compiler errors in your console, need to scroll up to see what's the offending scripts/errors

[thorny silo]

i transferred it to a new project

but yeah, idk what to do about this

[indigo finch]

hmmm... could you click on the top red message and let me have a look at what it says?

[indigo finch]

feel free to jump in @viscid reef

[thorny silo]

the visual studio one?

[indigo finch]

the next one. that's just a warning, not a critical warning

[indigo finch]

yea... im not entirely sure whats mucked up. on the console tab (the one with all the errors), in the top right there is three dots. mind clicking on that and maximizing? there are quite a few errors

[indigo finch]

ah, I ment..

[thorny silo]

ohhhh my bad

[indigo finch]

no worries

[indigo finch]

okay, would be best if someone else jumped in as i don't exactly know whats going wrong. that being said, I do have some basic things to check. first of all, what sdk are you using? 2.0 or 3.0?

[thorny silo]

3.0

[viscid reef]

go to packagemanager and make sure cinemachine is installed

[thorny silo]

This is my first time ever using udon

also just did that

[indigo finch]

are you use to sdk2.0, or are you knew to map making in general?

[thorny silo]

I'm used to 2.0

[indigo finch]

ah, gotcha

[thorny silo]

figured it out, simple light probe placer was making errors

[indigo finch]

wow... that would have been some digging to find. glad ya good now

[thorny silo]

thanks man

[indigo finch]

no prob

[indigo finch]

Is there a way to call the buttons on a VR controller? I know you can do
Input.GetButton("Oculus_CrossPlatform_Button4")
to get the left menu button, but what would be the others? I tried doing button3, but it just gives errors. Do I need to set it up somewhere? Is it protected and not available? Thanks

[dim wharf]

https://docs.vrchat.com/docs/input-events

i mean..

the buttons on the vr controllers have their functions for opening the menu and muting and stuff

so i dont think you should rlly do that

[scarlet lake]

👁️ 👄 👁️

[indigo finch]

there are times where their intended use doesn't really work (aka, trying to use a menu while in a car is completely pointless right now)

[dim wharf]

well, i dont think theres any input for what youre looking for srry

[indigo finch]

ah, all good

[cobalt trail]

This is a question from my BF whos question either got lost in chat or wasn't seen. In his recent world a quest user and a pc user cannot be in the same instance and he has no idea why? He's tried deleting literally everything from the Quest side and the quest people still just instantly crash out. Pc users are totally fine?

[wary kernel]

Possible a quest crashed only

[cobalt trail]

We think it's from a quest update or whatever, we don't know, only an assumption. Only quest people are the ones crashing when in an instance with pc users.

What could be causing this issue or rather what can be done about it? this is the first time a world he's made has done this to him and I have no idea why lol. It's an SDK3 world btw.

[vague agate]

Hello 🙂 , is there a way to compile only when you want instead of auto-compiling when programming with Udong Graph?
As graphs are automatically compiled, even small changes take time, slowing the work down. So I was wondering if there is a way to compile only when I want. Thank you for your reply.

[floral dove]

There can be networking issues if there are any differences in the object hierarchies between the Quest and PC versions of the world. If you submit a support request with this info and the world ID, we can try to reproduce the issue on our side where we can generate some Quest Crash info.

[floral dove]

There is currently no option to turn off compiling. It can help to keep your graphs smaller when possible. FYI, compiling is not typically the step that takes a lot of time, but rather reloading the graph when you make certain changes like connecting new flows or adding/removing variables.

Can you share a picture of a graph that takes a long time?

[warm blade]

Does any one know about a good window rain shader ? or something like that? xD

[cobalt trail]

Uhhh where would the support request be?

[floral dove]

you might have better luck in #shaders or #world-development, this channel is specifically for Udon

[warm blade]

oh shit sorry forgot xD

[vague agate]

here 🙂

[cobalt trail]

I'm guessing the actual request page is what you mean? so I don't do a derp over here ;p

[floral dove]

yeah, that's a lot of nodes to reload. It can help to break down your graph into smaller, reusable or connectable parts

[floral dove]

http://help.vrchat.com/hc/en-us/requests/new

You can find all the support info at #vrchat-support

[cobalt trail]

Yeah I figured, just clarifying is all, thank you.

[cobalt trail]

He submitted a request, thank you for replying.

[vague agate]

okay 🙂 thank you for the reply.
Is it okay if I ask you one more thing?
When there is a bug that compiles incorrectly differently from the logic shown in the right-hand node graph, is there a way to rewrite it while maintaining the objects connected in the inspector to public variables as much as possible?
Since I am dealing with notes related to the piano, it is very difficult to connect many audio objects every time.

[floral dove]

Hm, I'm sorry I don't understand what you mean.
Your inspector variables should stay connected unless you rename them. I see that you're working on a Midi piano, which is awesome! I love playing piano and I'm glad to see you're working with Midi. I wonder if there's another way to build what you're making without needing to connect so many audio objects.

[vague agate]

I'm sorry my English is not good because I use it with a translator.
Thank you for saying that. I'm a beginner piano, but I love to play the piano and I'm happy to be able to play music on vrchat,thanksyou for your work 🙂 .
Can you tell me again what you mean by this verse? Are you saying there is a way? ("I wonder if there's another way to build what you're making without needing to connect so many audio objects.")

What I originally wanted to ask is that the graph doesn't work as it is in the current state of the graph and it seems to work a little differently, so I'm going to create a new graph file and try to run it. However, I wonder if it is possible to create a new udon program file while maintaining the existing inspector state without reconnecting the 88 note and piano animation objects in the inspector. (The udon behavior does not recognize when multiple objects are dragged at once.) I can't seem to.)

[floral dove]

Hm - you can try this:

1. Make a backup of your project first in case this doesn't work
2. Delete everything in this graph except the Variable nodes you want to keep.
3. Redo the rest of the graph

If you don't delete the Variables, they should stay populated in the inspector

Connecting 88 objects by hand sounds tedious! Perhaps you could make it easier. If the notes are all children of a single parent object, maybe you can simply reference that parent object as a variable, and then use a 'For' loop to get the 88 children in the graph.

[vague agate]

Oh I understand. It took me a while to understand English. Thanks for the advice. As you said, first, after erasing the nodes except for the variables, rewrite the graph, and as you said later, we will arrange the contents by listing the audio, etc. under the parent object in order, and then loading them.
Thanks for replying today.

[floral dove]

No problem at all, you write english much better than I write Korean 😛
Good luck with your project!

[vague agate]

thankyou~! 🙂

[lavish wadi]

Hey, i've found an udon graph that allows me to reset a deck of cards back to their original position, but at the moment the button will only reset the cards that the person pressing it touched. So if I pick up two cards, and another person picks up two, and I press the button, only the two I picked up will reset. I want them all to reset regardless of who presses it. I could use some help fixing this problem if anyones willing!

[floral dove]

if the cards have VRCObjectSync on them, then you can use the .Respawn() method of that class to restore them to their original positions instead of managing your own locations variable. Either way only the owner of an object can update its variables, so you'll want that person to become the Owner of all the items first. You can learn the basics of Networking and Ownership here: https://docs.vrchat.com/docs/udon-networking

[lavish wadi]

Thank you! Super new to this stuff, i appreciate the response

[hazy galleon]

in 2019, can we add dependencies using Unity's Package Manager instead of copying in the binaries yet?

granted not really an Udon question, but it does relate, because I would like to be able to get updates more smoothly

[floral dove]

You can do that for any third-party packages that support UPM, yes. We'll offer support for our own SDK Packages through a separate VRChat Package Manager, coming soon to a Closed Beta near you

[knotty bison]

"copying in binaries"? Do I even wanna know what that means in terms of potentially trying to learn how udon works? Or should I just turn around now and forget I even looked in here before I potentially go mad?

[floral dove]

You don't have to worry about that yet. Hakanai just means that you import our SDK package the usual way for now.

By dragging-and-dropping it into your project

If you want to learn about Udon, I suggest this reading order: #udon-general message

[plush stump]

How can I set an object only visible to certain player?

[narrow stratus]

unfortunately i can't get the teleportation to work at all

i knew this tutorial would be outdated

like is there like a new way to get the teleportation to work instead of using a private string to put "enable" in it

[tacit harness]

https://i.imgur.com/hLAP4Ed.png

I have this canvas i have set it up exactly how i did with all the other ones i used but idk why but it looks like the layer i interact with is way to far to the front

like here you see that it still shows the interact blue dust or whatever thing even when im not pointing at it

https://i.imgur.com/og5bQrI.png

In unity it looks completly fine to me

https://i.imgur.com/xpFd6th.png

if anyone is able to tell me why or how to fix it please dm me or ping me in here

[narrow stratus]

turns out i forgot to turn on the trigger thing from the collider

hopefully it works this time

[narrow stratus]

welp it only turns off the collision

looks like i can't even to get the trigger to work at this point

there's probably no way to get it to work until vrchat makes a dedicated component of it

[toxic glen]

How do i make pickups global?

I don't know anything and want to be able to bean someone with a Blitzball

[tacit harness]

add a object sync to the object

its a script

so click on the object press add component and search for object sync

[tacit harness]

When you use a collider for a trigger make sure Is Trigger is enabeled on it and then inside of the udon script use a OnPlayerTriggerEnter asa event starter

[toxic glen]

😅 It's just as easy as adding that one thing? No fiddling with Udon Graph or anything? Wow i feel stupid

[tacit harness]

xD no worries i thought it was hard too at the beginning

[toxic glen]

I appreciate it

[narrow stratus]

box collider or udon?

[tacit harness]

So for an example :

https://i.imgur.com/9t0dPsH.png

this is how my collider looks

and inside of udon you wanna use this event to start whatever you are trying to do with it

[narrow stratus]

alright

[tacit harness]

Or wait sorry i might have understood you wrong

[narrow stratus]

oh

[tacit harness]

you want it to be a clickable button or like a area you walk into ?

[narrow stratus]

yeah

[tacit harness]

wich on of the two ?

[narrow stratus]

i kinda wanted to walk to it instead as entrance

[tacit harness]

Oh yeah then i did understand you right

[narrow stratus]

while the exit is clickable

this is how i set the trigger teleportation using a outdated tutorial from 10 months ago

i don't think this is the right way to actually set up the trigger

nor this when you spawn from the teleport

i just wanna make sure i'm actually doing this correctly from the old tutorial

or actually where do i put the "OnPlayerTriggerEnter" then?

i'm very new in using udon which is why i'm having issues with the teleportation

like i'm into more onto the art side of things than coding

yeah i think i'll had to start over

i don't know how to add a trigger to teleport

if a tutorial of this existed after the 2019 unity update i would've already got it working

sorry for the tiny vent though

[quick basin]

Does m3u8 work on quest?

[scarlet lake]

Does anyone know how to setup the 8ball table

[night viper]

@worn shadow This is the setup you could use. When a player interacts (clicks) they will set the bool "IsOpen" on the animator "FrontFloor1" to the opposite of what it already is (UnaryNegation) Every time you click (interact) it will do the opposite. From true to false and so on

[worn shadow]

I tried that one too. that was the first one I did.

Someplace I am going wrong and can't find it

[night viper]

Did you reference the animator on the Udon Behavior? (public variable)

[worn shadow]

yes, trying it again

[night viper]

Also, with Interact events, you have to put the Udon behaviour on the same object the collider is on. (it needs a collider to players can click it) You would put it where the knob collider is

[worn shadow]

@night viper were in the world do I find the Get bool

[night viper]

Search for: "Animator" enter, then search "getbool"

[worn shadow]

@night viper Now I lost the variable nod too.

https://gyazo.com/6f14bbebdb911d752a6b927e31f3c745

[night viper]

Try dragging from the node itself, much easier to find them.

[worn shadow]

The add nod look up as a mess

[fiery yoke]

I agree. But how do you think it could be improved?

[worn shadow]

Not sure just yet still learning. @night viper Just showed me something I did not even know you could do.

[night viper]

There are some settings you can change. To do what i showed on video make sure this setting is turned on

[worn shadow]

@night viper yeah saw that in the little video you sent, that definitely makes it easier. Now how do I get the variables to show back up in the Udon Graph? I have it set to show but it's not showing

Think I may have deleted when I started over.

[night viper]

Im not sure. Even if you delete all the variables the box should still be there.

[worn shadow]

Humm, it's gone, Always said I can only script errors

@night viper And still not working in test build. not even the "Use" showing up when I hover over it

[night viper]

Do you have a box collider on the same gameobject as the UdonBehaviour? (not sure if mesh colliders work, or if you need to set them as convex first) Can you show a picture of the gameobject where the udon behaviour is?

[worn shadow]

@night viper https://gyazo.com/c89e66b26b00ff479ac9da94d54c8bd6

@night viper Mesh Collider on the door none on the door knob at the moment.

[night viper]

The Interact event needs a box collider to work. You can add one. Add Component -- Box collider. Then you should be good.

[worn shadow]

@night viper Was gonna ask would the fact the the door knob is parented to the door and the door is parented to an empty that has all the doors parented to it?

[night viper]

That should not be a problem on your case. Only when moving objects. If you move the parent, their children will move with it. When the door opens, the knob should move with the door since it is a child of the door.

[worn shadow]

@night viper Thank you got it working finally. Now this should work with the windows too but I need to add an additional bit to it the windows have locks on them that need to work too , but I think that may be a bit more complicated. Thank you so Much Squall

[spring moss]

Can anyone help me change all player avatars on world entry? I need all players to be a specific avatar ID.

[night viper]

You are welcome, if you need help setting it up ask here! People will help you, even if looks complicated!

[worn shadow]

Thanks. Will make the Animations and get what I can set up before doing the Script part.

[inland sail]

Anyone know a prefab for beerpong ? Would be helpfull 🙂

[dapper lion]

https://github.com/VrcUdon/Udon/tree/master/Games/Beerpong

[inland sail]

using this but it isnt really nicely done, the ball is infinite bouncing and increasing height by it self and the ball is so bouncy its just to hard to hit a cup

[dapper lion]

this us literally the only udon one. fixing the ball is a world creator thing. in fact: pretty sure its written in there

find physics material -> set bounciness to wanted level -> ctrl+s

the only other ones were sdk1 and 2

[unreal grail]

I have a very weird question. I have a camera that takes a photo of a target with Camera.Render. However, if the target is not actually in my field of view, they are always a-posing—I think it has to do with the camera rendering before the model snaps into position. Any way to fix?

[grand temple]

yeah, I've seen that issue as well. I haven't bothered fixing it though. A normal camera doesn't have that problem, so you could just enable a normal camera and let it do it's thing normally instead

[unreal grail]

What do you mean? Render a normal camera first, and then take the picture?

[grand temple]

no I mean enable the camera for a frame so that it's able to render normally instead of telling it to render

[unreal grail]

I see, ok.

[grand temple]

it might also be that you need to render twice. The first would make the objects visible, then the scripts involved would set the bones. Then you wait a frame and take another picture. That might work

[unreal grail]

Awesome. Thank you so much.

[honest night]

hey, I was curious if anyone could point me in the right direction to a tutorial or resource for creating a toggle for a light?

I found a tutorial that kinda touched on it at the end but it was for SDK2 and I can't follow along with it 😦

[cunning mist]

If you have the light as a gameobject, you can do a little toggle like this

[desert grove]

GameObject local toggle.

[hushed gazelle]

I'm trying to get a video player to output its current time as hh:mm:ss, and I think I've got all the right pieces but the output's looking off. Is this how the nodes should be laid out or do I need milliseconds for the current video time?

[hushed gazelle]

I got that working properly, but different question now; How am I meant to use the Slider OnDrag node? They're not Events to start from, at least as far as I can discern.

[idle hull]

I'm having trouble with teleportation I made this script but instead of teleporting me to my spawn(tele) it flings me backwards

[tacit harness]

Im still having an issue where the collider or whatever of my canvas is way to far to the front and i dont know why

[fiery yoke]

Are you talking about UI Sliders?

[hushed gazelle]

Yes

[fiery yoke]

There is no OnDrag event. Instead you use the OnValueChanged event in the Slider component, to send a custom event to the UdonBehaviour

[nimble root]

On interact this removes 4 planes but it doesn't seem to return them after the delay. What am I missing on this? Thanks

[mighty fjord]

I don't believe the use of multiple custom event nodes in the same graph are supported

Are they?

[nimble root]

It seems to be multiple custom events with the same name is impossible. I did just figure out my problem. By attaching the last Set Active on the left group to the SendCustomEventDelayedSeconds it properly returns all the game objects.

[mighty fjord]

Good job 👍

[last junco]

anyone now if its posable to get a players avatar rank from vrchat ?
or if its posable to read the text on there name tag ware there avatar rank is ?

[fiery yoke]

Not possible.

[last junco]

rip

word be nice to have

[scarlet lake]

Can anyone help me?
I don't know anything about Udon, I would like to make a triggher that when you go against a collider triggher, a sound is activated.

[desert grove]

There are loads of examples in the sdk sample scene. Take a look https://docs.vrchat.com/docs/udon-example-scene

[indigo finch]

Having a weird UI issue with text mesh pro. It looks fine when the cursor is to the left of it, but when I move it past the beginning, it suddenly turns all blocky. Any idea what's going on? It only happens in-game, and not with CyanEmu

[desert grove]

Did you try testing in Unity? Using CyanEmu you can press the play button and just test your content in Unity without uploading. The benefit is that if something goes wrong you can check the console or inspect the element for changes. But here is a thread about other people and their fix for blocky letters https://forum.unity.com/threads/what-causes-text-to-be-rendered-as-blocks-instead-of-letters.555085/

[chilly crater]

I had a tester crash last night when the master left my test private upload instance. Can that be caused by objectpools having items without an objectsync component?

[indigo finch]

Thanks for the advice.. I guess?... my last sentence was literally "it only happens in-game, and not with CyanEmu".
Thanks for the link though. I'll check it out

[chilly crater]

Did you mess with the sorting layer?

[indigo finch]

yeah nah, the link's a dud. These guys are having issues on launch, where as for me it shows up fine, just that when the cursor goes to the right of the text it goes all blocky. if i keep it on the left, it appears completely normal. also doesn't seem to be a problem for any on the other buttons. tried duplicating text from one of the other buttons, but it doesn't seem to help

[indigo finch]

kinda. from the package it was set to 0, but that caused problems with the background, so I put it to 1 which new 'text mesh pro' texts are set to by default

never mind, got it happening in cyanEmu too. though further away

[broken bear]

it was happening to me on one of the interim-2019 sdks, make sure you have the latest

[scarlet lake]

it still doesn't work because I don't understand the basics, even if I watch the tutorial.

isn't there something easier to understand?

[desert grove]

🤷‍♂️ Kind of hard to know how another person learns. If tutorials and examples don't do it I have no idea. Maybe someone will break it down further for you... What I can tell you is that Unity is not MarioMarker, or any other drag n drop development engine. You need to do your homework to gain any understanding.

If you want to know what Udon is and how it works consider reading the whole document which the first link was pulled from https://docs.vrchat.com/docs/what-is-udon

[indigo finch]

Udon can be hard, expecially with the lack of biginner tutorials. The last thing we need is someone being elitist and saying 'just look at tutorials' or 'just read the documentation', as that stuff is so criptic when you first start out, so feel free to post you questions here. there are those that are willing to help newbies. As for your question, it seems you got lost, and the answer is rather simple, though there are some quick and dirty ways to do it too. Here's definitely the better one:

[scarlet lake]

i love u man

[worn shadow]

Morning all. I am working on a lockable door set up, I found a good video but it's outdated and not using Udon. I am having trouble translating the out dated parts to udon. Any help would be great.

[indigo finch]

While I wouldn't recommend it, you could also have a gameobject that 'plays sound on awake'. that would look like so:

[scarlet lake]

i have to make mario kart game on vrchat

[indigo finch]

And last but not least, you could have an animator with an animation that plays a sound. also can do things like 'open a door' or something

[scarlet lake]

So I need the sound of the coin to be activated when it is taken, the coin is deactivated and reappears 30 seconds after the last collision.

[indigo finch]

hmmm... not gonna lie, you should probably hold off until you know a bit more. make a basic hangout would with toggleable mirrors and what not. coins included. cars are a whole beast of their own

[scarlet lake]

for now i'm strotturando the map, but i want to start with udon

[indigo finch]

you would probably want an animation that hides the collider (and probably the coin), and make the animation take 30 seconds. otherwise you could do a timer

[scarlet lake]

I am using a box pickup to test the collision between coin and box collider in udon

[indigo finch]

gotcha... welp, here would be how to do the timing of it. you can certainly play around with these kinda things while your learning. Perhaps ignore the cars and just do players? that would be fun an a tonne easier to code

[indigo finch]

im asumming you just need a bool check to do a lockable door, right? is this tutorial using udon or sdk2?

[worn shadow]

@indigo finch It's not using Udon at all it's from 2018. Let me get a screen shot of it. Sorry if it's hard to see there UI ia really small in the video

[desert grove]

There is a kart prefab that you can play with. Requires UdonSharp though https://github.com/kurotori4423/KurotoriUdonKart

[scarlet lake]

I'm reading even if I don't answer, however I wanted to do it with cars, because the position of collisions on go-karts has a lower latency

[worn shadow]

@indigo finch https://gyazo.com/4b6c0a94089d9ec5b6646094813f1daa

[indigo finch]

I've tried it, it's pretty broken. certainly not where i would send a beginner

[scarlet lake]

the players if they are assigned a capsule to each, you see the capsule go late, and I preferred a more mariokart system. the time it will take me to make it doesn't matter to me, I just want to learn and test for now.

[indigo finch]

yea sorry, that's sdk2, not udon. i started world making when udon was released, so i wouldn't know. if you try and use it on an sdk3 unity file, it will just spit errors

[indigo finch]

sure, sound all good to me. personally, I've been looking for a good car prefab to use for fun, but haven't found anything yet. Just thought i would let you know

[worn shadow]

@indigo finch Yeah so trying to translate that to what it would be in Udon; The Equivalent. But not finding the right trigger.

[ebon wyvern]

Hi, I'm ENKY's helper for map creation, I'm trying to learn Udon too. Can you make it make a sound when you take the coin?

[worn shadow]

@indigo finch Here is an screen shot of the Animator if that helps. https://gyazo.com/048f02892af69fddb1bcce47de6ed004

[scarlet lake]

most likely me and pavel will be using existing go karts for the moment, Pavel knows C # so he is more advantaged making and editing C # scripts for me.

[indigo finch]

so sdk3 uses udon, which is basically c# (with saftey restrictions) and completely overhalls and replaces the trigger system of old. so a bunch of scripting like stuff would have to be done. it shouldn't be hard, but a little daunting if you haven't used it

[desert grove]

With the kart prefab there is a bug that can trap the user in the kart. I do not remember the fix, but in the script there is a function that locks the player to the kart itself. I converted it to an if/else to fix it. Pavel should have no issues tracking it down if they understand C#. And if I had the fix/or remembered it fully I would share. Other than that, the kart system is effective and "functional".

[worn shadow]

@indigo finch Daunting is ok. This can't be as complex as what @scarlet lake is attempting. I have doors working took a day to find out what I did wrong but I finally got it with help from yall here. This really this is for the windows that have a lock on them. The animations are done but making it all work is another story. LOL But I think it's the next step, Doors work now make locks right?

[indigo finch]

in udon, you would likely just toggle the collider, but if you look at the 3rd pic i sent for IEMKYI, i showed how to call a variable in an animator

[worn shadow]

@indigo finch the doors and windows are interaction on click or touch, not auto open when the player hits a trigger box if that makes a difference in how it is done.

[indigo finch]

@scarlet lake, here's a rough draft of how to do a coin collection system. hopefully i got my greater than and less than symbols right, but at the very least it should show you kinda where to look

[worn shadow]

@indigo finch I pulled that one up, that how I will get the sounds to work as well right?

[scarlet lake]

for now we have tested your first example, but it doesn't seem to work. Yet it is the same identical.

[indigo finch]

do you have a trigger coldier on the model? aka, box collider with the 'is trigger' selected. the object with the script will need it

[indigo finch]

can i see the model in the scene?

[indigo finch]

yea... if you do it by animation that is. you could always do it via script. unforntunately, it seems to be slipping my mind exactly how you just do one call of an animation... i could do it with a timer to bring back the bool to default, but im sure there was another way...

[indigo finch]

... that should work... unless I'm missing something. is the object making the sound got both a: audio on awake, and b: is un-active beforehand?

[scarlet lake]

by default the audio is deactivated so as not to start it when join in game

[indigo finch]

it is currently active in the image you sent. you want to deactivate it before playing for that script

[worn shadow]

@indigo finch The idea for the doors is to play the opening and closing sounds next. For the windows they will need that as well but they have the addition of a toggle-able lock. The lock is a separate mesh and is a child of the window pane it's self.
Show here with the lock open. https://gyazo.com/61f5bad42d117a260d1d15b3b4ae48ff

[indigo finch]

yea... that needs to be done with an animation. think you can just call it but...

[worn shadow]

And I'm sorry if I ask a lot of questions or don't understand at first, the Door was the first time doing anything with Udon, This is my first project for VRC

[indigo finch]

no no no, its completely fair enough. I'm just working on the script alongside the rounding out of Pavels and IENKYI draft script too

[worn shadow]

@indigo finch It's all good I'm fooling around in udon seeing if I can make heads or tails. I will say Udon is much easier for a non scripter to use then trying to learn LSL

[indigo finch]

Welp, that's good. cause you may need to debug this if i've missed anything. hopefully it will give you an idea of where im going with it

[worn shadow]

@indigo finch Thank you! At least it will give me something up to date to work with.

[indigo finch]

No worries. glad i could help

[worn shadow]

@indigo finch Oh boy; Looking at it now. Not sure what I need to change in the Animators to get this all to work lol. Or were this script goes, the main part or the lock that is the child?

[indigo finch]

yea... just looking over it i can see it's broken... give me a sec

[indigo finch]

Here... I even added some much needed comments. Will need to click door once to open, and once to close. dunno why I was trying to do it on a timer

[indigo finch]

okay... so... shouldn't have rushed the code out...
here are three parts, with some changes. first, the manager that has just had a custom event added. second the locking button that i forgot to make a variable public and third: another script for telling the door to open. in case you wanted a button for that too. will work without it

[indigo finch]

and just to answer your question as it seems i didn't (whoops), the animator needs to have a bool, that when true makes the door open, and when false makes the door close.
The door_manager goes on the door, and it needs to see the animator and needs to know the name of the animator's bool variable.
The door_locker_button goes on the button that locks and unlocks the door. Currently, if you click it it will make it locked, and if clicked again it will unlock it. It needs to see the door manager script, but that is the only variable it needs.
Next is the newly added Door_interact_Button; that simply needs to see the door_manager script to tell it to open the door (if not locked).

hello, i'm having a strange problem where the udonsync player syncs youtube videos fine, but when i try to play something from a webserver it plays too but it doesn't synchronize for the other players, only locally. what could be causing this? i'm using the unityplayer

[indigo finch]

Not the audio source. You want that to be active, but the gameobject as a whole should be deactive, as that is what the script toggles on. The other script I sent (as a file, let me know if you just want an image (will be big) ) would be more suited to what your doing. Can't say that it's bug free though, as I didn't check it much

[indigo finch]

Oh dear, should have read this a bit further back. There is a difference between 'object to object collision' and 'player to object collision' (onTriggerEnter vs onPlayerTriggerEnter). I would get cyanEmu, a free prefab that let's you play test in unity with a player that you can control (and triggers onPlayerTriggerEnter and what not). You will need to also get udon# for it to work, but both are free and you won't have to change how you code if you have them, just that all my examples will work in-editor.

[floral dove]

do the other people have 'untrusted urls' turned on?

[pallid remnant]

If there's one person who has them turned off would that stop it from syncing for everyone else too?

[floral dove]

only if they're the owner

[pallid remnant]

hm i see, i guess i'll have to do some more testing then.

i thought they did have it enabled but i would not know how to explain in otherwise

[floral dove]

you can add a VideoError event node and have it show any errors on-screen

[verbal socket]

how do you make a toggle sync to everybody ?

is it adding a sync thing to the thing your toggling or the button itself ?

[cunning mist]

https://youtu.be/O3VeBzV9HgI

There's lots of different ways, and this doesn't make use of the networking update unfortunately, but this should work fine for you.

[floral dove]

you can read about how networking works in Udon here: https://docs.vrchat.com/docs/udon-networking
the UdonExampleScene shows how to sync a Toggle: https://docs.vrchat.com/docs/udon-example-scene#toggle

You can try either Avatars Help, General, or creating a support ticket via the VRChat-Support channel's links.

[shrewd heart]

Thx

[tepid raven]

Would anyone be able to help me make a simple Udon script that plays a sound when you click something?

I haven't the foggiest idea of how to get that to work

[glass shoal]

Your first issue was using Udon

[tepid raven]

Not helpful, but thanks

I'm already on Udon, so what do I do?

I have an Udon graph that LOOKS like it should work, but then I can't define what sound I want it to play

[grand temple]

you need a public audiosource variable. You can tell the audiosource to play. Then in the inspector of the udonbehaviour, you would drop in what audiosource you want

[tepid raven]

I started over from scratch. I've got this much

Making a new Udon Behavior Script

I got this far

Does this seem right at all?

[grand temple]

yep

the playoneshot function requires an audio clip though, so you can plug in an audioclip from anywhere but you probably just want to grab the existing audio clip that the audiosource already has

so search for an "audiosource get audio clip" node

[tepid raven]

This is all I can find

or is it this?

[grand temple]

yeah that's it

[tepid raven]

So like this?

[grand temple]

yes, but you disconnected the audiosource from the playoneshot. You still need that

[tepid raven]

So like this instead?

[grand temple]

you need both

[tepid raven]

Oh lol ok

[grand temple]

at the same time

[tepid raven]

Like so?

[grand temple]

yes

[tepid raven]

Wew!

Time to test I guess?

Hmmm

It says I can click on the object, but no sound plays, and it also has no hitbox anymore

[grand temple]

is the audiosource assigned in the udonbehaviour's inspector?

[tepid raven]

Oh- derp...My Audio Source was unchecked

That did it!

Thank you so much @grand temple!

I've literally been trying to get help for this for months

You're the first person to give me a straight answer 😛

[grand temple]

😬

where have you been asking? I try to watch these channels when I can

also the ask forums

[tepid raven]

I would always get MOST of the graph but I was missing that last bit about the Get Clip node and how to arrange it

I usually asked in here or the world development channel, but I've admittedly been quiet for a month or so working on other things

But I'm getting back into my world dev again

[grand temple]

oh yeah I mostly watch the udon channels, not the world or avatar channels

[tepid raven]

I'll just pop in here more often then. And the forums of course

[thorny silo]

anyone have any ideas as to how to fix these errors?

[grand temple]

try reinstalling udonsharp

[chilly aspen]

I have a U# script and a C# script in my project. Is there a way the regular C# script can call a function on the U# script and get a value returned from it?

Currently in the C# script, I execute the following code:

int number = U_Sharp_Script.GetNumber();

But I get an error. NullReferenceException: Object reference not set to an instance of an object

[grand temple]

are you talking about editor scripting? If you're wanting this to function ingame, then everything has to be udon

[chilly aspen]

Only for the editor. The C# script has methods not exposed to Udon, so I need to compile some data in there first. Was looking for a way however where the C# script can communicate with the other U# scripts in the scene.

[grand temple]

I think you need trygetprogramvariable

[chilly aspen]

Okay I found a solution.

[astral sluice]

how do i stop a song from playing after it starts?

[grand temple]

if you're just telling an audiosource to play, you can also tell it to stop

[astral sluice]

idk how to do that i just started

[astral sluice]

thank you

[indigo finch]

[stray junco]

hi

i have some issue that prevent's my UDON world to be uploaded to VRCHAT

here is the UCEL-(UnityConsoleErrorLog):
System not supported exception udon does not support variable of type "image" yet

what does this mean?
and how to resolve this error?
🤔

thanls in advance.

[cold raft]

i think some of your udon scripts make a variable of type Image and that is not supported

[stray junco]

@cold raft
yeah that's correct
but it's not mine it's from github asset simple UDON C...S... StartManager.cs
so there is no way for me to code it?
...like for example that i can replace some syntax or something

because i'm not able to find any resolution to this particular thing

[cold raft]

can you link the github?

[stray junco]

i will
please hold on...

nope not that one sorry

this one:
https://github.com/Toly65/UdonCombatSystem

[cold raft]

do you have udonsharp installed?

[stray junco]

yup

without that UCS it works
but with it i can't upload my world

so u# is not the problem

as you can see
and yes i did all vrchat's ,u# instrructions but no use

[cold raft]

i dont see anything wrong, this can happen if you got like an older version of udon sdk

[stray junco]

nope
