udon-general

[slow coyote]

yeeah, at some point, there's going to be additional data that's going to be tracked, so I suppose individual data objects would be the route to go. I guess this turned out to be more of a rubber duck moment, lol.

Thanks anyway.

[dusk lance]

Cant wait for per player programs so that giving every player data will be much easier.
Is the vrc object pool stable enough so that on player join, taking ownership, and trying to spawn is enough to give every player an object? Im worried about the edge cases. I’m still using Phases pool system for now as a side step but would like to have something using the pool object instead.

[floral dove]

Also - keep in mind that we'll be adding support for a "Player Object" as part of the upcoming Player Persistence project this year, where each Player can be auto-assigned an object, and the variables on that object can be persisted between sessions. While we can't give you details of exactly how this works yet, if you build things with this pattern in mind, you will be able to migrate them to the persistence system later.

[floral dove]

It should be! But we've yet to do a big test. I could build a simple test along those lines to try at the Community Meetup. I'll be out of town this weekend but we could do the next one.

[slow coyote]

Really looking forward to the persistence stuff.

[dusk lance]

I would offer to write one as well and test at the meetup, but I showed a world at the last one so I’m also waiting a week.
Having it in graph form and super simple would help a lot of creators.

[gloomy wind]

Omg persistence ! Neat !!!

[fading cipher]

Persistence confirmed this year?!

[wanton oxide]

That is soo good

I literally already wrote a system to do just that haha

So adding persistence would be super easy

[muted sinew]

hey everyone, im having some trouble with my udon script, i am trying ot make a door disapear/reappear when i click a button but instead of the door disapearing, the button itself disapears
could someone take a look at my string and let me know if there are any errors within it?

[floral dove]

what do you have set as the 'door' GameObject in the inspector?

[flint urchin]

Did you remember to set the door object as the variable in the inspector?

[floral dove]

jinx! personal lock

[chilly crater]

How would I go about making a HUD UI for VR? I can't use a UI canvas

I'm trying a on object on an update loop positioned on the tracking data, but that is really jittery.

[rose mauve]

anyone know about setting custom colours to vrcbilliard?

[flint urchin]

If you do the position update in LateUpdate (no lerp) it shouldn’t jitter. Ofc a bit easier to tell what’s going on if you have any pictures

[chilly crater]

I wouldn't really call it jitter... It slides opposites to how I'm rotating and then catches up.

    {
        if (Networking.IsOwner(Networking.LocalPlayer, gameObject))
        {
            var owner = Networking.GetOwner(gameObject);
            var trackingData = owner.GetTrackingData(VRCPlayerApi.TrackingDataType.Head);

            transform.position = trackingData.position;
            transform.rotation = trackingData.rotation;
        }
    }

... late update...

derp

[chilly crater]

There we go, thanks. Got the lateupdate and fixedupdate confused

[muted sinew]

i had just a simple cube i made flat

[floral dove]

this graph should work if you have the right object set as the target, ie the 'door'. Can you show a screenshot of the inspector for this UdonBehaviour?

[muted sinew]

yes im fairly new so im just trying to figure out where it is

[rancid edge]

So udon is like a programming language?

[chilly crater]

Yes.

[rancid edge]

Do I need any programming background to learn how to use it?

[chilly crater]

I would watch a few tutorials on youtube about it. It's based on C#, so you knowing syntax, a few generalities and whatnot will only help.

I'mma simp Vowgan. He explains as he goes along. What he is doing, how he is doing it, and why he is doing it.

https://www.youtube.com/channel/UCMLgCTDbjvOjMRsyLLbuuqw

[muted sinew]

it seems overwhelming but its not super bad just kinda technical
ive been watching this guy
https://youtu.be/6ZaBCVMOMWE

@floral dovei ende up redoing the whole door and this time it worked? im not sure if i just needed to restart but that was super weird

[floral dove]

hm, that looks right from here. I just built that scene and it worked for me 🤔

[rancid edge]

Could I realistically just watch tutorials and learn how to use it? Or do I need the coding foundation because I don’t mind trying to learn C# I’ve always been interested in programming, but I just want a fun way to pick it up so I was hoping Udon would be a good outlet.

[muted sinew]

thanks for the help, i think its because my button was too close to the door

[chilly crater]

Udon Noodlegraphs is great starting out. And then you start hitting limitations (like graphs becoming more and more difficult to decipher as you go on) and then you move onto UdonSharp.

[muted sinew]

nah you dont need a foundation i have zero background and im just picking things up here and there

[chilly crater]

That's what happened with me.

[rancid edge]

Ahhh great

I’m hopping on this then after seeing someone getting a video player to work for quest I assume with udon I wanna try to do some cool stuff like that as well

[muted sinew]

im sure youll get the hang of it!

sorry to ask a multitude of questions but does anyone know if we need vrc world to allow jumping?

[floral dove]

jump is 0 by default, you need to set it to something above 0 to allow jumping. If you use the VRCWorld prefab, it has a program with this already set up.

[muted sinew]

ah gotcha thank you

[trail shard]

How do I interact with the variables in one udon script from another?

[grand temple]

You would need to have a reference to that other udonbehaviour and then you can do setprogramvariable and getprogramvariable

[trail shard]

The udon behavior or the object that the udon behavior is on?

[grand temple]

the udonbehaviour itself

you can do that by just making a public udonbehaviour variable and then dropping in the other udonbehaviour into the slot in the inspector

[trail shard]

The udon behavior component you mean? Or the script?

[grand temple]

yes, the component

[trail shard]

so then when I get the program variable, for the symbolname should I just type the name of the variable I want to get?

[grand temple]

yep

[trail shard]

How would I edit a float variable from this?

[grand temple]

plug in a const float

[trail shard]

Into value I'm assuming

[grand temple]

yes

[trail shard]

There's clone, get sync root, and get value, those are the only 3 that come off the value node for floats

[grand temple]

huh? I'm not sure what you're looking at

[trail shard]

when i drag off the value node from the setprogramvariable there's no constant float option, only clone, get sync root, and get value

[grand temple]

yeah just don't plug it in like that

make a brand new node and drag it into value instead of dragging away from value

value is a generic "object" type which means it can accept just about anything, so dragging off of it like that isn't really going to work

[trail shard]

Ooh ok, I figured value was the value of those variables

I stg I don't know how yall figure this shit out with no documentation or tutorials I'm floundering like a dead fish

I guess dead fishes don't flounder though. I'm floundering like a dying fish*

[grand temple]

setprogramvariable used to be the only way to set anything

at a certain point the thing where you drag in from the side bar was added, and that's basically just a shortcut that does the same thing as setprogramvariable

[trail shard]

Do I need a specific event on the other script to detect like an event of the variable changing or something?

[grand temple]

no, but you can send a custom event to it after setting the variable

only if you need it to react to the change

[trail shard]

Well i'm having it update a text object that displays the float

and the only time that happens is on start

[grand temple]

then yeah, do exactly that

send a custom event and have that redo the text

[trail shard]

ok so that works now, but it only adds 0 and 5, I'm assuming I need to use the get program variable node to get the actual value of the float because the moneymanager script stores that value

[grand temple]

yeah exactly

you would get the moneymanager's money value and plug that into the addition

[trail shard]

Do I do that off of the object output of the getprogramvariable or is that something I'd just have to make another separate node for

[grand temple]

yes, straight off getprogramvariable

[trail shard]

like this?

[grand temple]

hm, I thought it would do the conversion automatically. Does it not let you plug the object directly into the float?

[trail shard]

Oh it does, the colors are tripping me out I just assumed that wouldnt work I guess lol

if I try to interact with it more than once it gives me this error

Nvm just had to recompile both scripts

Sweet everything works now awesome. So by default this should only be local right? I don't want the money value updating for everyone, obviously, everyone needs their own local money value

[grand temple]

Yep that's all local

[trail shard]

Awesome thank you so much!

[autumn sparrow]

Question. How would I go about destroying an audio source once it finishes playing? I don't know if there might be a better node than using a delayed timer approach

[inner timber]

you generally just want to be pooling objects and enabling/disabling them

[shy osprey]

is there a way to share a variable between multiple objects? and can that variable be different for each person? (i assume this is what public variables are but i cant seem to figure those out)

[slim hound]

Each udon behavior will have its own independent variables but you can copy and set variable values between udon behaviors

[floral bear]

Hello, I modified an Object Pool script to work on interact and have a set spawn location. I'm testing it with 2 clients, client 1 can spawn objects, client 2 can't.
There is also a garbage bin which returns objects to the pool, but if client2 throws a spawned object in the bin client1 can no longer spawn objects, or rather I can see them spawning but returning to their pool instantly.

[slim hound]

Only the owner of the Object pool gameobject aka the master by default will be able to call trytospawn successfully

[floral bear]

Is there a way around this?

[slim hound]

I have my own way of doing it but it could be considered somewhat jank

Easiest way is to use player on enter trigger though

[floral bear]

better than nothing, I suppose 😅

[grand temple]

just take ownership when you try to do any operation like trytospawn or returning to the pool

[floral bear]

I'll look up taking ownership, thanks

Transferring ownership on interact worked, however spawned objects return to the pool after about 1 second.

I disabled the script that returns them to the pool when entering that trigger but it seems that's not what's causing the issue

[chilly aspen]

Does anyone know if USD or crypto payments are possible through VRChat?

[cunning mist]

In the future, you will be able to have paid subscriptions to certain users, and from what I can tell, Udon will be able to know whether or not a user is subscribed to the world creator. I am uncertain if that payment interaction will be linked through steam or ran internally, though none of the purposed systems allow for say, pressing a button in a world and bringing you to a checkout page.

[chilly aspen]

Hmm, okay.

[cold raft]

on vket that had those buttons that opened a browser page to a shop, but luckily thats not available to the general public

[chilly aspen]

Yeah, without payment rails market places aren't really possible.

[chilly aspen]

I have 3 Udon world ideas I was wondering if they were any good.
1) A VRChat NFT Exchange where players can mint and collect NFT art.
2) A VRChat Bazaar where players can advertise for-hire services to other players.
3) A VRChat Market where players can trade ownership of worlds.

[cold raft]

great idea's when the premiun subscriptions are out, you can sell advertising space to subscription holders and cash in on the moneys!

[tough hull]

Uhm, is it possible to download the VRChat SDK with only the steam account?

[cold raft]

Uhm not through normal means no, also i dont think you can uploads or avatars without a vrc account anyway

[tough hull]

Damn

Alright

I guess I'll have to remember that

[cold raft]

but the good news is, vrc accounts are free!!

[tough hull]

True, but inviting friends will be...

Difficult ;s

And I will have to find my avatars again ;(

[cold raft]

no you can migrate your steam account to a vrc one

in ingame in the settings menu you find the upgrade account option and follow the instructions

[tough hull]

Oh interesting

Thanks!

[west mural]

can we ragdoll players with udon using the combat system ? if so, how ?

[rose mauve]

anyone know how to customise the colours on the vrcbilliards table

for each team and such

[fading cipher]

Is there an easy way to make it so I verify a script's Start() has run before I try to tell it to run a method?

oh wait

execute order

[fiery yoke]

The Combat System is more of a relic at this point, since you can make your own combat system.

Except for ragdolling. I made a canny about that and its "Under Review" as of May 11th
https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback/p/ability-to-ragdoll-the-player-via-api

[west mural]

upvoted

[gloomy wind]

😢

No System.Action, I'll try delegate

[grand temple]

no, just pass a string and an udonbehaviour and then do sendcustomevent

[gloomy wind]

That's the only way to go?

[grand temple]

pretty much

[gloomy wind]

So I can really have a generic event to listen for

I can't have any observer pattern like this

I guess, I'll just put an array of Behaviors and send the custom message then

[grand temple]

yeah

can't do udonbehaviour arrays though, gotta do component arrays and cast to udonbehaviour

[gloomy wind]

And I guess, those events can't have any parameters?

What if I make an interface and I call the method of this interface?
I guess that's the same x) ?

[grand temple]

yeah nothing like that, that's all C# shenanigans

[gloomy wind]

ah ah x)

[grand temple]

you can use setprogramvariable though

[gloomy wind]

Ok I'll think about that

Yikes, I'll set my observers one by one x)

But that's completely logic :x

[gloomy wind]

How does SendCustomEventDelayedSeconds work?
I tried to put 5 seconds and it didn't work 😦

Nevermind SendCustomEvent doesn't work either

[grand temple]

I don't see why that wouldn't work 😕

[gloomy wind]

It doesn't work from an udon graph too
I'll investigate a bit more

[cold raft]

Well it should work, if had it working before

[inner timber]

Is there a public method with the same name on the same behaviour, and do you maybe need to be the owner?

[gloomy wind]

Ah yes probably

I have only that

I'll try with another name

[floral dove]

it may help to add a Debug.Log at the top to see if the event is getting called and just not having the effect you expect

[gloomy wind]

Yeah I mean, ResetAllBricks is called and the behavior is working as expected

But it seems to work with another name now

[inner timber]

One way to make sure you're consistent with spelling and for renames to not break code is to use the nameof() command instead of a string

[gloomy wind]

Good to know!

Really strange cause I was copy pasting the name of the function. I thought it was because the method was not public but not really

https://im3.ezgif.com/tmp/ezgif-3-d7493fa3868c.gif \o/

(I'll probably destroy performance on Quest but meh it's fine for now x) )

[broken bear]

I feel like a dummy, I've yet to do an udonbehavior and it work the first time out. This graph is suppsoed to control a menu. It starts disabled. On a click of a interactive object, it enabled the menu object, and teleports the menu to a fixed location. On a second click, it turns the menu object off. Intention is that the menu is teleported around the map on the click of different points in the area, on a fresh one it will activate and teleport to that location. Right now I click it and it does not show at all in game. In cyanemu it teleports, turns on for one second then immediately turns off. I'm at a loss.

[floral dove]

It's not a good idea to share values between different flows right now, like you are for settings MenuOn from MenuOn > UnaryNegation to both the True and False flows of the Branch node.

You could simplify that by simply setting MenuOn to its opposite before you go into the branch

but even easier would be to skip the part where you save the state of the menu in "MenuOn", and instead just check whether the GameObject is active (using .activeSelf)

[broken bear]

Thanks, I'll revise, and get rid of MenuOn alltogether I think with that, a symptom of just trying to get the flow of it in my head

[floral dove]

take a look at the example graph called "ToggleGameObject" which is included in "VRChat Examples" and used in the example MirrorSystem:

you can start with this, then get activeSelf after the SetActive call and branch on it to move the menu if it's now active. You can also use SetPositionAndRotation to simplify those two calls into one

something like this:

[broken bear]

that's much cleaner, I'll try that

[broken bear]

Still having issues. Interact goes to SendCustomEvent (_MenuReset). Menu object is off by default. First interact should SetActive to true and both Logs should output "True". It then goes to the branch check and Log should output "BranchTrue". It is outputting True, True, BranchTrue. However it's not teleporting the object now. Maybe there's an issue of SetActive on an object and immediately setting its transform at the same time? More importantly subsequent interacts is not toggling, it's always logging True, True, BranchTrue each time. (in a live upload and not cyanemu) I'm teleporting this menu element around so I'm not having to make 9 copies of the same menu in the map, I may just do that and do a normal toggle, but really interested why this isn't working as I may use it in the future for other things

[floral dove]

for that branch in the middle - maybe try setting it from a new GameObject.getActiveSelf instead of UnaryNegation. It's possible that it's negating the value after you've changed it. Did my version of the graph not work, where you check 'activeSelf'?

[broken bear]

it would check False first, Toggle True, then the branch check to see if it's supposed to teleport but it was reading the initial False, so I pulled in the UnaryNegation one instead

it could explain it, I put a log on the interact event after SendCustomEvent to output "InteractEvent". The log reads : True True Branch True InteractEvent. I would tihnk Interact event would be the first outputed. so maybe something in the order of what is being processed here. I'll do a new GameObject.getActiveSelf check and I may have the teleport transforms in its own CustomEvent

putting the transformation into its own group/event seems to be working, maybe it was trying to reposition an inactive object in just the order it was processing things

[trail shard]

Is there a node to get a script to wait a certain amount of seconds before going onto the next part of the script?

[glad flume]

Hello, I am new here.
I have a question related to data collecting.
I want to do an experiment using Udon on VRchat.
and I want to know whether I can collect the interaction data ongoing VRchat world.
Thank you

[trail shard]

Maybe the fax analytics prefab on this page could help? I'm not sure exactly how it works but it sounds like it might be useful for you

https://docs.google.com/spreadsheets/d/e/2PACX-1vTP-eIkYLZh7pDhpO-untxy1zbuoiqdzVP2z5-vg_9ijBW7k8ZC9VP6cVL-ct5yKrySPBPJ6V2ymlWS/pubhtml#

[floral dove]

Look at the SendCustomEventDelayed events, you can use that to break up your flow.

[fading cipher]

Can you not VRCInstantiate things with mirrors in them 🤦‍♂️

Actually uhh this i sjust weird

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

Shows up in scene but not in game?

[cunning mist]

Lol that's a weird one
But yeah you should almost always rely on objects that exist in your scene rather than instantiating something. If you need a large amount of something, try using an object pool.

[fading cipher]

Nope

We're instantiating everything, no object pooling

We have already successfully solved networked instantiating and we're partway through ownership transfer (there are some bugs)

But now I have to figure out why you can't see this mirror in the game 🤔

But I just confirmed my mirror issue isn't an instantiating problem...

eh, I must've removed mirrors from the player camera for some dumb erason

okay so... does cyanemu always default to not displaying the mirrorreflection layer?

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

Or is it not supposed to?

Because I can only see my mirror in game view when I enable rendering of that layer in the cyan emu player camera's settings

[cunning mist]

Mirror Reflection is a layer that only the mirror is supposed to see, the player never sees it. Mirrors don't go on Mirror reflection.

[unborn hornet]

Mirror reflection layer interfered with my pens. Had small colliders on ink joints for the eraser to collider with, but since they were on the reflection layer, they seemed to interfere with the reflected avatar somehow, causing the player to slowly sink through the floor.
Switched to walkthrough instead and it stopped sinking players.

Super freakin bizarre

[grand temple]

were the colliders set to istrigger?

generally if you're gonna use mirrorreflection to avoid disrupting interacts, you'll want to also have them on istrigger so they don't collide with anything. If you do that they should be 100% unnoticeable

[fading cipher]

What layer do you set mirrors to then 🤔

Default?

[grand temple]

mirrors can be on pretty much any layer

as long as you can see it

[fading cipher]

ah ok, thems goin to walkthrough then

Thank you!

[grand temple]

oh neat, I was just about to write up a description of each layer but I googled to see if anything like that already existed and there's this http://vrchat.wikidot.com/worlds:layers

Great write up, I approve

[gloomy wind]

Neat!

[fading cipher]

Unity giving like a billion nullrefs the moment I enter play mode, that's a new editor-break bug I've never seen before now apparently it somehow failed or interrupted compiling and that was just a bunch of udon script failures

[acoustic vale]

Any recommendations for YouTubers who do full build series for udon? Like start to finish building a project (if that exists at all)?

[cold raft]

not any i know of, best help for udon scripting for me was Vowgan but he also says he wishes there where more udon tutorials creators

there is ofcourse the offical vrchat youtube channel that has some basic tutorials but its limited in scope

[fierce verge]

What node do I have to use to take a URL that I can type in as a public value

instead of using an input field, so I can use a button to play a video

[gloomy wind]

string

Should be a yellow pin

[fierce verge]

ahhhh I was thinking of the name but I couldnt get it

was on the tip of my tongue hahaha

thanks 🙂

what do I need to connect it up?

I needed a VRCURL smh

[gloomy wind]

I'll double check during my lunch break but check what are the functions available to create a VRCURL (maybe thanks to one string)

https://ask.vrchat.com/t/set-custom-url-with-a-string-for-the-video-player-system/3409/3 Seems there is no answer here

[grand temple]

there is no way to create VRCURLs at runtime by a script, that's on purpose to prevent the world from just using it as a generic web request

you can create VRCURLs in two ways: either a public variable that you add in the inspector before uploading the world, or that players can manually put in with the VRCURLInputField

[grand temple]

To answer the original question though, you have a URL as a string variable. That's not going to work. Instead just have a VRCURL variable and mark it as public

[fierce verge]

I just did that but thanks anyways

[grand temple]

ah, sorry

[trail shard]

How do I detect collisions with a specific object, or specific type of object?

[grand temple]

you can check the name of it and if it matches or contains a string

[trail shard]

So could I use an oncollisionenter event and a string compare?

[grand temple]

yep

[void ridge]

If you're careful, you can also use Layers for this

You can look at VRChat's physics collision matrix under Project Settings --> Physics

If two layers don't collide with each other, then collision or trigger events won't be generated

You can also use Udon to check what layer something is on and filter it that way, so you can use a combination of any of the three types of filtering

[fading cipher]

If you want to optimize it further, you could use a specfic letter or character at the beginning of an object's name and if (name[0] == 'a') or something to specifically verify if it matches the letter :3

Not quite sure how much, but slightly more optimized to check a single letter than checking for an entire string of text in a name

[fading cipher]

Does VRCInstantiating an object automatically zero out it’s rotation even if the prefab has a rotational offset?

I guess I could just re-apply the offset by getting the original prefab’s rotation, but I want to verify that’s the problem lol

[gloomy wind]

@grand temple Name and layer are very limited, so I prefer to get component (especially working with UdonSharp)

[grand temple]

that certainly works too. Nothing wrong with either really

[fossil bison]

Me and my friends do a lot of formation flying on the flight training map and we were just wondering how the radio systems are going to end up working

[gloomy wind]

Sure

[gilded grail]

question, does on Interact only fire for the person clicking a button or will it fires for everyone in the room? I want to make sure im setting ownership to an object correctly

[cunning mist]

Correct

[fiery yoke]

Its local, so yeah the first

[gilded grail]

cool thanks

[fossil bison]

Does anyone in here have any information on how the radios will end up working in the flight training map they just added

[grand temple]

This channel is for general questions about udon. There is no way we could answer such a specific question about one particular world. You'll have to ask the author of that world directly. Perhaps they have a discord server or twitter

[tidal sand]

Yo, how do I attach a udon graph to a player?

Basically I want each player to "own" a networked entity.

[floral dove]

you can learn the basics of ownership in VRChat here: https://docs.vrchat.com/docs/udon-networking#object-ownership

[tidal sand]

Okay, how do I spawn a gameobject with a UdonBehaviour component for each player?

I want each player to have variables. I would like to add a "Health" variable for each player.

[floral dove]

combine that with OnPlayerJoined (https://docs.vrchat.com/docs/event-nodes#onplayerjoined) and an Object Pool (https://docs.vrchat.com/docs/network-components#vrc-object-pool) and you'll be on your way

sure- you can add a 'health' variable to the UdonBehaviour on the Networked Object that you assign to each player.

[tidal sand]

Sweet, thanks!

So all I have to do is create a manager-like entity that listens to OnPlayerJoined, fetches a "PlayerVar" entity from the pool and assigns it to a player, who then takes control over that PlayerVar entity, is that correct?

[floral dove]

Yes, that sounds like a good approach

[tidal sand]

Awesome, thanks!

Another question: if I invoke a CustomNetworkEvent, can the receiver of that event know where it got called from?

[floral dove]

unfortunately not.

[tidal sand]

Let's say Player 1 has pushed a button which has called a CustomNetworkEvent on a, say, a door entity. Can the Door entity know which player has triggered that event?

Hmmm, so it's like calling a function with no parameter or return

[floral dove]

that's right - Events currently have no parameters or returns

[tidal sand]

all the other side knows is that the event was invoked

[floral dove]

however - you can have a trigger collider on the door which can trigger an event when the player enters it. This event includes a reference to the player, so you could cache the 'lastPlayer' who entered a collider.

Or have the player take 'ownership' of the door, change a 'currentPlayer' variable to themselves, and then trigger the event

BTW - it sounds like you've got a good grasp of programming concepts. I recommend you check out UdonSharp if you haven't already (check the channel pins)

[tidal sand]

That wouldn't work I'm afraid: i'm assembling a melee combat system. The receiver (the dummy box who's getting hit by the sword in this case) has no guaranteed proximity of the weapon striking it. Worst case scenario, the weapon hasn't even approached the dummy box on the master client's game due to latency

[tidal sand]

Already am using it! but thanks!

[floral dove]

hm - for the case above you may instead be able to use a trigger or collision event on the dummy box. If it's hit by a sword, it can get the owner of that sword.

[tidal sand]

I'm a networking engineer and I've been developing games for a while now. VRChat is a pretty interesting opportunity to create a light RPG-esque experience. First challenge is to assemble a damage system that works for melee-based combat, hence the questions

[tidal sand]

But then the dummy would be responsible for doing all the damage calculations, right?

As in, if the client (who is not the master client, owner of the dummy) smacks the dummy with a sword, the dummy would only call all the damage methods when it's hit by the same sword on the master client's machine

This latency might make the weapon not feel responsive enough, you feel me?

But it would make everything much easier, doing everything "serverside"...

[grand temple]

I was completely unconvinced that melee combat could ever be good until I tried Cyan's draw your weapon. I was very impressed

[tidal sand]

There's a functional melee world out there? I should take a peek to see how they've solved these issues

[floral dove]

Yeah, I get you. You could have the player take ownership of the door and change the health of the door if you want it to feel more instant, but that will fall apart if you have multiple players hitting the door.

[tidal sand]

Exactly. Since it's a multiplayer RPG experience, players are very likely to strike the same "NPC" all at once.

[floral dove]

Until we have events with parameters, this will be an issue. Even then, since only one player 'owns' the door, it's possible for the events to arrive out of order, or the player to send a 'hit' event to a destroyed door, etc.

[tidal sand]

i'm gonna have to do some serious code gymnastics here to sync all the info beforehand the strike actually lands. The strike can only call a single method: DealDamage(). All other info must already be sync'd to the Dummy's owner client (most likely the master client) before this happens

[floral dove]

You could try having people take ownership of the door before they hit it but if many ownership changes happen quickly, there may be some desync while things catch up. Never actually done this so we don't know for sure.

[tidal sand]

i'd like to not change ownership of the dummy/door because I also plan on running some very primitive AI logic in there and that should only happen on the master client/"server"

but I can see how that'd be useful...

This is a tricky thing.

[floral dove]

This sounds like a fun challenge, but be advised that you're trying to do something here that immediately runs up against some of our current networking limitations.

[gloomy wind]

Hey! Personally I did a brick breaker game and my ball just send a message on server and break the bricks without issue

So a sword held by any player on server could inflict damage on a target

[tidal sand]

Hmmm...

I mean

you're totally right: it will deal damage

the thing is, would it feel responsive?

ACTUALLY

[gloomy wind]

Damage are never responsive in any game

[tidal sand]

i'm being REALLY stupid on this one. It doesn't NEED to be responsive

Yeah

[gloomy wind]

Action is

[tidal sand]

the EFFECTS should be responsive

[gloomy wind]

I mean in multiplayer game*

Yes so you can predict them

[tidal sand]

the damage calc itself? no need. impossible, even

wow i

you're totally right.

[floral dove]

you could change the values to 'damage' locally but still send the network event - that way you have the 'effect' play immediately and then everyone else will get it a little later.

[gloomy wind]

But prediction is something complex for VRChat

[tidal sand]

Yeah

All damage calc should happen "serverside", including collision detection and all

locally we just check for collisions and play effects accordingly

[gloomy wind]

Momo are you a dev or just a moderator that love the game 😄 ?

(Was wondering that even if that's off topic)

[tidal sand]

Say, if i pick an object up (VRC Pickup), am I automatically assigned as its owner? Do I gain authority over it?

or is it still owned by the master client?

[grand temple]

yes it will automatically set you as the owner

[tidal sand]

shucks

[grand temple]

only if it has objectsync

[floral dove]

I'm a VRChat dev! I mostly work on Udon and the SDK 🙂

[gloomy wind]

Awesome job then 😄

[grand temple]

if you need desynced behavior you can just not add objectsync

[gloomy wind]

I didn't even try to understand how my brick breaker was working. Since there was no bug but I'll dig a bit master/authority to try to help you Bonick

[tidal sand]

No see, that's the catch: I need this pickupobject to be sync'd. I need its transform to be replicated from the current holder but i need its vars to be handled by the master client

Cheers!

If I manage to come up with a viable melee-damage solution for this test world I'm making, I'm willing to share its code with the community

could come in handy

I'm going to try and handle everything serverside. What are the chances the master client's machine doesn't detect the collision from a melee weapon/particle?

[floral dove]

If you want VRChat to handle transform&rigidbody sync for you, then the ObjectSync component will do that, but it does require changing ownership of the object. If you don't want to change ownership, you'll have to roll your own sync system for that. Like have the player pick up a dummy object, and constantly update the position of the actual one from the dummy's position, etc.

[tidal sand]

Yeah, either that or parent it to the player's hands, somehow

[floral dove]

you can't 'parent' anything to the player - so you would just constantly update the position of the object based on the player's hand trackers / bones, yeah

[tidal sand]

But nah, I don't want to go against VRC's architecture anyhow

Yo, i thought i should ask

Any ideas as to when we're getting those RPCs with parameters?

i mean not gonna lie to ya, these would make my life much easier here!

[floral dove]

Yeah - so say we all! I'd expect them to release this year, but we don't have them slated for any timeframe more specific than that, sorry.

[tidal sand]

Aight that's fine

you guys use Photon as your networking framework, is that correct?

PUN or some form of it?

[floral dove]

Yes, we use Photon for some of our networking.

[gloomy wind]

Were you inspired by Unreal Blueprints to create the UdonGraph ^^ ? Looks similar in the node names

[dapper lion]

udon is literally noodles....

thats my guess as to why it is graph

[gloomy wind]

I mean 🤣
The visual scripting part

Should we ask udon graph features in #feature-requests ?

[tidal sand]

Yo, is there any way to test a world with multiple clients and make sure the client that gets assigned to my HMD is just a regular client and not the master client?

[gloomy wind]

I think I saw something in the SDK notes

[dapper lion]

canny.io ?

[floral dove]

launch 1 client with "Build and Test" with force non-vr turned off, then launch X clients with it turned on.

clients launched with Build & Test will all go to the same instance since it's a local file

[timber knot]

Who's udon?

[tidal sand]

is force non-vr a launch arg?

and if so, is it a launch arg for Unity or should I slap that into Steam's launch parameters?

[floral dove]

https://docs.vrchat.com/docs/using-build-test#launching-multiple-clients

[tidal sand]

OH silly me

I just saw the tickbox.

lmao.

but thanks!

[floral dove]

it is a launch arg, too - --no-vr

but yeah, we have the built-in checkbox to make it easier. The checkbox just appends the launch arg to the internal command it generates.

[gloomy wind]

It's so quick to iterate, I'm so happy x) (When you work with c++ and compilation took 1 hours to do a full build Client+Server 🤣 )

[tidal sand]

I see. Thanks!

On another note, Unity takes a while to build my world. I take it its generating an assetbundle, right?

Is there any way to speed up the build/test process?

[floral dove]

That's correct. It can help to make simple worlds to just test some scripts out, but be aware that currently the mere existence of a prefab in your project necessitates a scan on that prefab. So if you have an asset pack with a lot of prefabs, it can take an egregious amount of time to build.

[gloomy wind]

On my machine, it's only 30 secondes to build/test.
You can also test dirtecly in editor

[floral dove]

When I work with big asset packs, I'll often import just the bits I currently need, or have a separate graybox project just to test functionality.

[tidal sand]

That explains it. I did import an asset package with a crapton of prefabs.

Will remove those!

I see that there's a limit regarding data I can sync. Are those values on a per udonbehaviour basis or per gameobject basis?

[gloomy wind]

Since we can't mix both, I would say it cumulates on the whole gameobject.
But it could be per behaviour 🤔

[floral dove]

those values are per-UdonBehaviour

[tidal sand]

Wew, i've removed all the extra prefabs and things are flying now.

10 seconds till VRChat launches, tops

Smooth sailing now

[floral dove]

nice! We have a few to-dos in place to make that easier.

[tidal sand]

Awesome!

Yo, another question: is there any way to check whether I have authority over a specific UdonBehaviour?

[cunning mist]

You could do branch for Networking.IsOwner(MePlayer, theGameObjectImLookingAt)

[tidal sand]

Sweet, thank you!

I can't find this in the API, what's the difference between Instance Owner and Master? Aren't those the same thing?

[floral dove]

https://docs.vrchat.com/docs/network-components#networking-properties
Master = First player to enter the world, will be given to someone else if they leave.
InstanceOwner = Player who created the instance, false in Build&Test and Unity PlayMode.

[tidal sand]

Got it, so i need to use Master in my case.

But then again, it also says that Master is "old logic"

[floral dove]

Yeah, there's very little reason to use it instead of "Owner" IMO.

[cunning mist]

Wait why is IsInstanceOwner recommended over IsMaster?

[tidal sand]

Hmmm. I just need an easy global way to check if I'm the master client or not

But InstanceOwner doesn't work in test builds

[floral dove]

You can check if you have ownership of whatever Object you're using for managing things.

[tidal sand]

ye, that'll do I suppose

if I check it against a child object of a UdonBehaviour object, will that still work?

[floral dove]

If you want to grant 'special abilities' to someone in your instance, Master will give it to the first person - which is you if you created the instance from the menu, but it will be Random_Person_3as9 if you dropped a portal.

[tidal sand]

if (Networking.IsOwner(myChildObjectGoesHere))

[cunning mist]

Oh, I thought Master was assigned to the person who loaded in first. Is that instead IsInstanceOwner?

[floral dove]

I don't think so but I'm not 100% sure. I think only the objects with UdonBehaviour / ObjectSync are actually networked.

[tidal sand]

Got it. i'll just fetch the udonbehaviour then

Thanks!

[floral dove]

You're correct - Master is the first person in.

[cunning mist]

Okay, than InstanceOwner is the one that dropped the portal.

[floral dove]

yes

[cunning mist]

I would still use Master for almost all of my checks, since I largely use Master for state comparison for late joiners, though I guess that's largely unnecessary now with the Networking Update.

[floral dove]

I wish IsInstanceOwner worked in Build & Test but unfortunately, those instances just don't have the data.

[floral dove]

Yeah - the Master player may not 'own' a target object, and shouldn't be used for late joiner comparisons

and you shouldn't need to 'compare' against another user for late joiners - they'll get all the latest data in their synced variables, and then OnDeserialization will fire so you can handle the data.

[cunning mist]

Right, but say in my video on synced doors, I have the Master check what the global value of the door is and send an event for the new person to get caught up. Again, this was largely for before the Networking Update though

[floral dove]

Right - that's unfortunately not a way I would recommend anymore. Players should handle the data themselves in OnDeserialization.

[cunning mist]

Definitely. All tutorials and information is destined to be antiquated and superseded, so I decided to make that video when I did in order to summon the update.
Similar to washing your car to make it rain.

[tidal sand]

Good news! The melee system is working pretty well so far. All clients (master or not) can pick up the sword and deal damage to the dummy box. Its health var is replicated to all players so hooray!

Now, my dummy box script was using Udon and not udonsharp. What's the attribute for replicating simple int vars over the network with udonsharp?

I remember reading about an attribute

[gloomy wind]

[UdonSynced] ?

[tidal sand]

That might just be it!

[floral dove]

FYI we don't officially support UdonSharp here so U#-specific questions are best answered via those docs or the UdonSharp Discord Server.
https://github.com/MerlinVR/UdonSharp/wiki/udonsharp#attributes

[tidal sand]

Oooh, my bad!

[floral dove]

no worries - plenty of people know about it here, but if you get into advanced stuff, you may want to drop in on their Discord. I can't link it here but it's easy to find.

[tidal sand]

Alrighty! I believe most of my problems might be more related to Udon itself and the API

but i'll join their server as well!

[gloomy wind]

Oh they have a discord 😮

[floral dove]

yep! Lots of advanced users over there.

[gloomy wind]

Thanks a lot

[floral dove]

don't forget about us over here tho

[gloomy wind]

Eh eh 😄

I'll still be there, you're the devs so we don't forget you 😄

In any case, I want to thanks your job, as a gamedev, it's so cool to iterate on this game engine (over Unity) and have the possibility to showcase to friends and more

[trail shard]

What am I doing wrong here? When I use the pickup it plays the audio but it doesn't wait for the 1.5 seconds

[floral dove]

Your instructions are:

1. OnPickupUseDown, Check if 'canbefired' is valid.
2. If it is, play Gunshotsound
3. Set 'canbefired' to false
4. In 1.5 seconds, fire the 'armed' event
5. (1.5 seconds later) armed: set 'canbefired' to true.

FYI - you can use the 'boolean const' nodes to get easy boolean values instead of Convert.ToBoolean

[trail shard]

Yeah, but it doesn't wait the 1.5 seconds and I'm not sure why

Like if I spam click it doesn't have any delay

[floral dove]

ah, I see - you're checking if 'canbefired' is Valid, instead of using a Branch node to check if it's true.

[floral dove]

BTW - I recommend you check out the UdonExampleScene that comes with the SDK to learn some best practices from working graphs. There's some docs explaining bits of the examples here: https://docs.vrchat.com/docs/udon-example-scene

[trail shard]

Aaah ok, I'm still learning all the different nodes I figured this was the right one. Whoops!

[gloomy wind]

isValid should not accept bool IMO (any primitive in fact)

[floral dove]

it accepts any Object 🤷

[gloomy wind]

but what is an invalid bool 😦 ? int or string

[trail shard]

so what was making the bool pass as valid

[floral dove]

I think all value types will return as valid because they're not null.

[trail shard]

Ah ok

[floral dove]

IsValid is mostly useful for checking if a reference type is null (or has some other weird property that makes it 'invalid', like a VRCPlayerApi reference which is not null, but refers to a Player who has left the instance and should not be used)

[trail shard]

Works correctly now, thank you!

[floral dove]

it should be used wherever you would usually use if(foo != null)

[gloomy wind]

Yes in C++, it's mostly to test that the memory is pointing to a valid address
So same in C#, an isValid on a primitive will always be valid tho

Maybe a suggestion could be to not accept primitives/value types on the "IsValid" node (if that's easy to do). So it will be error prone for beginners.

[tidal sand]

Yo, what's the difference between SendCustomEvent and SendCustomNetworkedEvent? And how do I call a networked event or RPC from UdonSharp?

(I'll ask some Udonsharp-related questions in here first because this server seems to be more active than the u# one)

[floral dove]

SendCustomEvent calls an event on a target UdonBehaviour, defaulting to 'self'. It's the equivalent of calling a method on a MonoBehaviour in regular Unity C#.
SendCustomNetworkedEvent calls the event on either the owner of the object or on everyone. I recommend this video / doc for learning the basics of networking in VRChat: https://docs.vrchat.com/docs/udon-networking

[tidal sand]

Ah got it. So SendCustomEvent is a simple method being invoked while SendCustomNetworkedEvent is an RPC

[floral dove]

yes. The UdonSharp wiki has some examples of calling events and RPCs: https://github.com/MerlinVR/UdonSharp/wiki/examples

[tidal sand]

Since I'm using U# and I can just grab a reference to another UdonBehaviour then invoke one of its methods, I take it that SendCustomEvent is not really necessary in my case, is that correct?

Ah perfect, cheers!

[floral dove]

Right - UdonSharp hides away SendCustomEvent and lets you just call a method by its name. It generates SendCustomEvent under the hood. Same for calling methods with parameters. It actually uses SetProgramVariable to set a variable on the target and then calls that event.

[tidal sand]

I see.

[tidal sand]

Hi! Is there any code called when an object is successfully initialized over the network?

I would like to disable some objects if I'm not the owner of an entity but I'm afraid this data might not be available on Start()

Like, the master client will have full control over NPCs. Other clients should disable AI-related components accordingly

[floral dove]

Start() should be a safe place to check for Ownership of a given object. The only thing that I know is not ready yet in start is IsUserInVR, which I believe is available a frame or two later.

[tidal sand]

Oh okay then!

I suppose I can't use StartCoroutine, right? If not, what's the correct way to wait for seconds in Udon?

[floral dove]

SendCustomEventDelayedSeconds or SendCustomEventDelayedFrames

[tidal sand]

Hmmmm, thanks!

Awww

I just meant to say that I just chucked the sword on the poor sod's head and he plopped down to the ground

it LIVES

damage feedback and all

okay this is very VERY exciting.

[shut lodge]

Hi, I'm trying to match location + offset to a stool (pick up) in my world so when a user picks it up. The Phantom stool will follow at an offset. I **feel **like this topic has come up before but I don't know where.So far when I run it any rotation on the stool is updating as it should but the position remains the same. Is there something else setting position? Any advice would help. Thank you!

ahh turned off physics

now it follows

[tidal sand]

What's the best way to calculate the velocity of a VRC Pickup object?

Like, I know it has a Rigidbody and Rb has its own .velocity var but that is not replicated over to other players. I need a local way to retrieve the overall speed of a VRC pickup object

[fallen prawn]

I think the ObjectSync rigidbody property seems buggy, so maybe 2 point check?

[tidal sand]

That could work, but my main concern is that this is a sword

it being a sword, th oh nevermind i can just add a transform at the tip of the sword and calculate the spatial difference

ye that'll do, cheers!

[chilly crater]

How do you get the gameobject from ObjectPool spawns? Do you just use it like a variable like var obj = HealthArmorPool.TryToSpawn();?

[fallen prawn]

Yes.

[chilly crater]

Thanks

How reliable is having a player return their object to the objectpool when they leave the world?

Or am I just going to have to fire a cleanup event whenever a player leaves and have the owner check their displayname against a textcomponent to return it?

[grand temple]

by the time you get onplayerleft, that player is gone and you can't rely on them doing anything else

[wanton oxide]

you can use onownershiptranferred and check if the new owner is master

if yes, that (unless you are doing ownership transfers to the master manually somewhere, you'll need separate handling of that) means that the original owner left

[wanton oxide]

(and if yes, check if the local player is the master, then return it)

[chilly crater]

I was going to say that that wouldn't allow graceful changes of network master. but changes of network master can be pretty bad for logic. I'll just throw everyone at spawn if that happens.

[wanton oxide]

it would allow for those though

if the network master changes, only the objects currently not owned by someone will change ownership to the new master

so it should still work for that situation

[chilly crater]

Man I'm really tired if I missed that... I need to finish this and get to bed. Thanks again and sorry for bugging you

[trim sapphire]

Hello! Sorry if this is a strange problem, but I was working on a world with UdonSharp yesterday without issues. I've now loaded up the project again today to continue work, but none of my scripts are compiling; every script in the project, even ones that were compiling without issue, now fails to compile with the error:
Assets/<class>.cs(7,0): System.Exception: User type <class> could not be found
Where <class> is the class that the script creates. I've tried restarting Unity, reinstalling UdonSharp in the project, and re-compiling all scripts in the project to no avail. Is this a known bug, and is there a known solution?

Here's the error happening in the console with the example scripts provided with UdonSharp:

[wanton oxide]

you should ask about this in the udonsharp discord

usually this is fixed by just reinstalling the vrc sdk, udon sharp and restarting unity tho

[trim sapphire]

Thanks! I'll keep the UdonSharp Discord in mind for next time.

[fading cipher]

Was there ever a plan to be able to pass RequestSerialization parameters of udonsynced variables so you don’t have to sync an entire object’s synced variables if there are a lot?

[cold raft]

You could track different variables on different behaviors

[fading cipher]

That’s occurred to me as a way to mitigate it, yeah

[fierce verge]

For some reason all objects inside my pool get set to deactive, while all i want to do is change their animator mode

[cold raft]

dont see why they would be set to disabled

but for the animators on the left you dont provide an instance

[fierce verge]

ahhh yeah

still they dissapear, as soon as I remove them out of the pool they dont

[cold raft]

i assume animator value "mode" = 1 doesnt make them disapear right 😄 as it could be that simpel 😄

[fierce verge]

no theres 3 modes

0,1,2 each mode has another animation

0 is default which is still

but as soon as I join the objects are gone

[void ridge]

Last I knew, inputting OnDeserialization into an input flow directly along with other input flows can cause the graph to not compile correctly. Try replacing all those flow noodles by sending each of those events to send a custom event--including OnDeserialization--and then receive that custom event as the only input flow of your For loop.

That should be functionally equivalent. Then see if it makes a difference

[fierce verge]

okay let me try

[void ridge]

Actually, I'm also seeing that you're using the node Animator.GetType when I'm pretty sure what you want is Type Animator

[cold raft]

ah yes i noticed that aswel i though both might work so i didnt complain about it 😄

[fierce verge]

the one at the bottom you mean

Fixed both those things but they still dissapear

[void ridge]

Yeah. I'm actually not sure why most of this graph isn't crashing your program, since if any of those nodes run, they should get a Null Reference Exception since no value is put there

[fierce verge]

I was told that if there is no instance it uses the one from previous data

thats why I had that there

but my problem is more why it disables all items in my pool instead of just working or not working

[void ridge]

I'm out of ideas, sorry. I don't know enough about Animators or what you're trying to do with these.

[fierce verge]

I have 3 animations, and 3 buttons

when I press a button the Int value changes and all items in the pool play that animation

when I press another button the vlaue changes again and all items play the other animation

but instead all items in the pool just vanish

[fading cipher]

Forgetting to tick force non-vr when you build & test

[fierce verge]

??

[fading cipher]

If you don’t get it, you haven’t done it

[inner flax]

what is udon

[fierce verge]

I have it on force non VR standard but that doesnt change shit, the whole behaviour stays the same

[fierce verge]

A coding language for world and avatar development

[fading cipher]

Yeah I more mean that all my VR apps start opening and it’s hell to close them all if I forget to force non VR lol

[fierce verge]

ahhh

[inner flax]

oh okay

[fading cipher]

WMR opens and chugs my computer, then the game opens and chugs a bit, then SteamVR as I’m scrambling to force close everything, then all my SteamVR plugin windows loading up at once

All for a single simple unticked box 😢

[fierce verge]

xD

[fading cipher]

It’s like that meme where everybody scrambles for the TV controller when that loud-ass THX sound comes up on VHS movies

Was it THX? 🤔

[fierce verge]

yes

[fading cipher]

Awesome, I somehow still remember

[gloomy wind]

I guess the VRC Object sync has a limited max velocity cause my objects are synchronized weirdly with others clients.
It seems there is a linear interpolation applied but this looks so odd 😦

It's a ball moving very fast. I guess 200 Bytes per second is to low
So I could write a custom code to have a better looking throwing feel but with prediction

[gloomy wind]

---

Does the VRC Pickup automatically give ownership over the gameobject when someone grabbed it?

[scarlet lake]

how to InputUse

[gloomy wind]

Listen for the event OnPickupUseUp I guess?

[scarlet lake]

I mean how to detect mouse click / vr trigger button

nvm i found out how to use it

[scarlet lake]

ye

[gloomy wind]

Ok so I have a synchronized ball that is thrown and can hit bricks to destroy them.
In fact I just realized there is no server entity (server authority) So it's all client side with one owner at a time 🤔

So I'm wondering how I could destroy bricks in the most clean way (I can change Ownership each time the ball hit a brick but it sounds to be very expensive for the network 😦 ).

Omg it's even worst 😭
My brickManager needs to have ownership too

Ah ah, I'll find a way or it will be only solo or 1v1 experience I guess

[scarlet lake]

Why do you need to change ownership?

[gloomy wind]

Cause only the owner seems to be able to return object to the pool

[scarlet lake]

OnTriggerEnter -> destroy brick?

Local only

[gloomy wind]

Yes

[scarlet lake]

If the ball is synced already

[gloomy wind]

No I want it to be synchronized

I can do it on both sides (Master and other clients for sure)

[scarlet lake]

Set the sync mode to continuous and it should be synced for everyone

[gloomy wind]

Why continuous 🤔 ?

Manual just need a request each time you hit

[scarlet lake]

But then nobody will see the ball move and hit the brick

[gloomy wind]

I mean not the ball the brick 😄

The ball is synchronized

The brick is manually updated
But afaik, I need to set ownership on the brick each time a ball hit it

[scarlet lake]

Yeah so when the ball hits a brick, brick should go boom?

The ball is already synced so why do you need to sync the brick

[gloomy wind]

Well, The bricks are ON or OFF (for now, I didn't put health, but I planned to)
Since they are managed thanks to a pool, the pool is owned by the master
When I destroy the brick -> I return the object to the pool

[scarlet lake]

If you have to network the bricks then send a custom network event

When brick go boom

tell everyone about it

[gloomy wind]

How expensive is that?

[scarlet lake]

but it will be slow

Better to do it locally when ball enters brick trigger/collider

[gloomy wind]

Let me try something first

[scarlet lake]

I mean slow like latency will suk not fps

Unless its a big boom

[gloomy wind]

Yes but if it's local any player that join or left will not see the game updated
Even any player that are playing

[scarlet lake]

Idk why you need to pool the brix

[gloomy wind]

Cause the state active is synchronized?

And I need to enable/disable the bricks when the game start or when they are hit by the ball

For all players (I want a coop gameplay)

[scarlet lake]

You can do manual sync request on player joined too

idk

[gloomy wind]

That's OnDeserization

[scarlet lake]

yes

RequestSerialization will call OnDeserialization

[gloomy wind]

Yes, I'll try without the pool but in any case to do that you need ownership 🤔

Or I'll just try the network event

But that's sad, we can't specify the target

Oh wait

[scarlet lake]

Does the owner always have to be the master tho

It can be anyone I guess as long as its a player that joined earlier they can send the active state on or off

to late joiners

[gloomy wind]

if(!VRC.SDKBase.Networking.IsOwner(gameObject))
{
  SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.Owner, "HitBrick");
}
else
{
  HitBrick();
}

I did that, I'll try it

So it's not as expensive I guess

But that's sad we can't specify the target gameobject

[scarlet lake]

When you send a custom network event it is always sent to the gameobject that the udonbehaviour is attached to

[gloomy wind]

Ok so It work but I can predict it to smooth the experience

[scarlet lake]

You can specify a gameobject with synced variables and GameObject[] arrays, just send the array index

Then you need to call RequestSerialization

Or do continuous sync

[gloomy wind]

Yeah could be better than the pool I guess

[scarlet lake]

ye we dont need hand holding do it ourself

vrc pool waste of time

its gonna be forgotten like the old combat system

[gloomy wind]

It sounded to be a good idea ah ah ^^'

Let me rework without a pool then

I guess it's lighter to have one array of booleans than one sync variable per brick (even if I'll probably need health per brick)

[scarlet lake]

dont worry about networking, just do it the easy way

its not 100 gb data we are talking about

[gloomy wind]

In fact the "Pool" was providing me a good architecture since I could easily switch between one bricks pattern, and one another

[scarlet lake]

tupper pays for it np

[gloomy wind]

tupper pays for it?

[scarlet lake]

ye just send the invoice to him

[gloomy wind]

🤣

[dawn forge]

You know what would be cool? I was thinking of making a database storage system to quickly save and retrieve information and make some mockup syntax like SQL

[scarlet lake]

u can use an encryptor for this maybe

and let people write down the code to save and type it in when they load

obviously make it hard to encrypt otherwise people will hax your game

[dawn forge]

Check this out @scarlet lake https://blog.foorack.com/sha256-hash-algorithm-in-udon-vrchat/

[scarlet lake]

thats super long though but looks interesting

maybe it can be compressed

[gloomy wind]

@dawn forge VRC dev are also working on persistence 😄

[scarlet lake]

maybe in 2024

[gloomy wind]

Not really they plan to release it this year 😄

But yeah I'm not them

[dawn forge]

Hell yeah, I can't wait for that. I was just wanting to flex on Udon a bit and see if I can make a mock SQL system. And someday if they ever allow WebAPI, you could have it easily talk to a SQL server for very persistent data management like Leaderboards, analytics, etc.

It is evident they're either halfway or nearly complete(going through testing) on the features they showed us. A semi-working UI update, dynamics, etc. I am sure they have the code written up halfway for persistent systems to work.

[gloomy wind]

Candidate to work for them 🙃

[scarlet lake]

it shouldnt be hard at all to implement

its just that it costs memory

[gloomy wind]

Sure it's not as hard but then you need to expose it for beginners 😄

That's the hardest part

[scarlet lake]

They could add a Load() and save(string data) methods, thats enough tbh

[dawn forge]

Not really memory, but the architecture. They will either store that info on the serverr and they deal with the burden of storage, or the persistent data is stored on PC. But that is a security risk.

[scarlet lake]

You just need to parse it yourself

[dawn forge]

For example, in Starcraft II mapmakers can setup variables that are persistent to help construct a leaderboard. I.e. Total playtime, total kills, etc. The SC2 team did implement a "signing" of the settings file where if it was modified outside of the game, it wouldn't work because the game has to make a new signature. Unfortunately people already found a way to fake sign the file and people are spoofing their scores/kills to literally 999999 to be on the top.

The same issue can happen to VRC too.

And all that data is just an XML file stored right in your PC.

What's worse is a map dictated if a person should have admin rights based on a boolean value in the setting file... Don't know why the creator didn't just do a name check instead, but people literally got ahold of the rights and just did random stuff in the map. The creator never fixed it lol

[gloomy wind]

The problem is that there is no dedicated server on VrChat

So anyone can write in the DB as soon as they are the owner / master (whatever you call it)

SOOO if they bring persistence, it will either work only through their server API so it will be a huge bottleneck or they will bring Dedicated server to the game right?

[scarlet lake]

They could implement a voting system

if all clients vote to write something to the db only then it should work

[dawn forge]

They will either have to have each person hold their persistent data via a file OR have the VRC API hold it. I don't know how they're recognizing Avatar 3.0 parameters at the moment but it will behave similar to that I believe.

[scarlet lake]

There is nothing stopping u from running ur own dedicated server in vrc though

just start a new instance and never leave

xd

[gloomy wind]

x)

You can try to start an instance on a machine (which is not headless) so you got your dedicated server 😄

[scarlet lake]

It would be nice to have a dedicated server in vrc with more than 40 max players, we can have our own database

[gloomy wind]

Ok let me try without the pool to see if it's responsive

Is it more responsive? 🤔

Oh no 😭

Got an out of sync some way 🤔
It's strange. I'll have to find why cause it should not be possible. If the state is synchronized

Ah I miss the OnDeserialization

So I guess I was only relying on the ball collision

Ok now the audio 👀

Ok I still have desynchronisation despite having used manual sync

@scarlet lake When RequestSerialization is called, it's calling OnDeserialization on all clients right?

[scarlet lake]

Yeah I think so

[dawn forge]

@gloomy wind I really like the arcade vibes!

[scarlet lake]

Even the owner

[gloomy wind]

Thanks @dawn forge 😌

[scarlet lake]

Im not sure tho so try it

[gloomy wind]

So yeah I send network event to change the boolean "Destroyed" on the owner or directly if I'm already the owner.
And I call RequestSerialization after the boolean changed so it should work 100%
BUUT in fact, when a player joins the map the bricks are not even destroyed

The pool was working in a more relevant way

[scarlet lake]

Then use the pool

[gloomy wind]

I don't get what I got wrong here 😦

Sad

Yeah for now, it will do the job

[scarlet lake]

Just Debug.log everything

If you wanna find the bug

[gloomy wind]

Yeah I'll put that in a separate git stash and will investigate that tomorrow

🤣

I mean, I'll definitely investigate tomorrow since I need to understand x)

[scarlet lake]

Sure sure, good luck

[lofty pewter]

any one know any good tutorial videos for world building?

[unborn hornet]

OnDeserialization is not called on the owner of the object. OnPreSerialization and OnPostSerialization are called on the owner.

[gloomy wind]

Ok but I don't need OnDeserialization on the owner since I call all functions

[unborn hornet]

Right. It just depends on how you want to architect the code. If it works, it works.

[gloomy wind]

I want the owner to do all the important job so I call everything on it

And others just call the necessary after deserialization

[lofty pewter]

is this where to ask about world building?

[gloomy wind]

#world-development then

That's more a general unity question

[broken bear]

This is an item that when held, and then interacted, it changes materials. It works locally, but it's not synching to other players. Each of the listed variables is marked sync. The initiating event is OnPickupUseDown->CustomEvent(_Interacted). the initiating event is marked as Sync method (Cotinuous) but the receiving object has Synch method (Manual), maybe both should be manual?

[gloomy wind]

Why do you sync the materials and renderer?

You could only sync the integer, that's enough

[floral dove]

is this the sender or the receiver? Assuming this is the receiver since it's using RequestSerialization

[broken bear]

Left two groups are the sender, thought I would need the receiver on the same game object but in this third group

[floral dove]

the sync method only really matters for the sender

start by just changing arraypositionSS - log the new value on the sender, then log what is received by the others.

once that's working, you can implement your whole material array system - and Bibni is right, only the integer should need to be synced in this case.

[broken bear]

ok I'll log for both, I was concerned it wasn't pushing anything to the receiver at all (using a friend to test and not 2 clients)

[floral dove]

much easier to test using Build & Test locally first 😓

that way you can see all your logs, etc before involving someone else

[broken bear]

Appreciate the help, really trying to get these fundamentals so I can move on to more complex things someday

used to program text-based MUDs in the ancient days and this is bringing back websocket netowrking memories to me

[unborn hornet]

There'a a certain amount of mood there...

[brave glade]

Rookie question, what is Udon?

I just hopped back on VRChat after 2 years

[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

[brave glade]

Oh, thank you.

[scarlet lake]

do anyone here have experience with udon and coming up with ideas? cus honestly i suck at this but i make a few maps
I really would like to make up a team to help me out.

[scarlet lake]

aka C-Sharp with Assembly code supported made in a visual manner.

[cerulean vigil]

how to put music on buttons?

[scarlet lake]

use a toggle or switch prefab

[fading cipher]

People: how to do thing
Good helpers: use prefab
Me: make it all yourself

every damn time I see a question in here

my brain, why

[bleak jay]

not everyone has the time, skill, or interest to make everything from scratch

[fading cipher]

Yeah and there's no point in reinventing the wheel lol

I completely agree, I just don't know why my brain defaults to that smh

[bleak jay]

i dont think thats a bad mindset either

some people just really like making stuff from scratch

[hallow pumice]

I had to move some rooms around the world. As a results, I had issues with the teleporters. I fixed most of them, but the last one still doesn't work. Instead of teleporting me to the destination, it seems to be choosing another teleport destination close by and sending me there instead. I've checked to make sure everything is pointing where it should in the script. I can't figure out what's going on. Is this something that has come up before? What should I be checking?

[wild kite]

umm i have a problem in vrchat atm and idk if everyone is having the same problem but when i load in and go to a world it brings me back to my home world does anyone know why its doing this??? @everyone soz

because i can't see the world and my socials thumbnails

[cold raft]

Uninstall your custom clients - reinstall vrchat try again

[elder leaf]

Uhhh is this normal?

Cuz the characters won't just load for some reason

Well some do but some don't

[cold raft]

thats the performance blocked avatar so they either violate some of your performance settings like max avatar size, or its a bug, if had happen a new time where an avatar was perf blocked while i basicly have my safety set to non existant and when i did press show avatar there was no reason for it to be performance blocked

[elder leaf]

So what should I do? ;-;

Cuz I remember putting it on unlimited I think?

Idk

[cold raft]

just select them and press show avatar

[magic kiln]

hey anyone have any clue how to create a slider to control bloom in the world?

[gloomy wind]

Unity Ui have slider components

[hazy summit]

Is there anyone aware on how to use UI buttons for avatars instead of Avatar Pedestals?

[chilly crater]

Does OnOwnershipTransferred fire for everybody, or just the new owner?

Nevermind. I had the wrong documentation up

[floral dove]

Use the UI button to call a custom event on an UdonBehaviour which has a reference to a Pedestal so it can call the UseAvatar Function on that Pedestal (or whatever that's called, I'm on mobile rn)

[hazy summit]

Like this?

[floral dove]

Hm - I'm not sure, you're using an add-on I'm not familiar with. The default inspector doesn't have EventName, etc. Take a look at the UdonExampleScene for many examples of using UI buttons to trigger custom events on UdonBehaviours.

[hazy summit]

Copy will try taking a look

thanks for the help

[floral dove]

Explanations of some of the UI examples here: https://docs.vrchat.com/docs/udon-example-scene

[candid wolf]

Bit out of left field but this is an odd issue I'm having

Because I can't attach things directly to bones with udon (due to not being able to attach to the parent bones)

I'm doing the next best thing, aka, getting the neck bone's position and rotation

And setting the object's position and rotation to match that bone's position and rotation

and that works...

On some avatars...

For some reason, and I'm not entirely certain why it's doing this

It's rotating the object 90 degrees

Both avatars have neck bones set up though, and I have no real clue what would be causing this...

TL.DR:
why does an object attached to a neck bone rotate 90 degrees on some avatars and not on others?

[fiery yoke]

Because there is no conventions on bone rotations. Humanoids in Unity are weird.

[candid wolf]

Any reliable way I could make the rotation relative to the head's rotation?...

[fiery yoke]

Sort of

[candid wolf]

(head bone has the same issue)

[fiery yoke]

If you make certain assumptions, then it will work, as long as those assumptions are not broken

[candid wolf]

Hmm... Actually, I think I just thought of a way to make it work...

Just spitting an idea out to see if you agree here

What if, when the object assigns itself to the bone and grabs the bone's rotation

it checks that new rotation against the rotation it had originally (which should be 0)

and just store it as an off-set

and just subtract that number

🤔

[fiery yoke]

Well that will work, as long as the bone rotation is at the default value at that point

kinda hard to explain

[candid wolf]

   public override void OnDrop()
    {
        rotationOffset = owner.GetBoneRotation(HumanBodyBones.Neck);
    }

    private void Update()
    {
        if (active)
        {
//Attach the necklace to the neckbone
            necklace.transform.position = owner.GetBonePosition(HumanBodyBones.Neck);
                                        //Get current totation                       //Subtract the offset (1 - 1 = 0)
            necklace.transform.rotation = owner.GetBoneRotation(HumanBodyBones.Neck) * Quaternion.Inverse(rotationOffset);

if the head bone is already oriented correctly, the offset should be 0

if it's 90, it'll pretty much be 90-90

(not really it's Quaternion, so 4d matrices n shit, but that's besides the point)

kinda wish there was an easy way to attach things to a player's bone though

cause that'd also help with client side/server side syncing

[candid wolf]

update: my theory works

hmm....

granted the player doesn't change their avatar...

is there a way to check that?

[candid wolf]

Answer, no there's not 😐

[scarlet lake]

Ppl be lazy and go the easy way

[dapper lion]

whats not working? the nechlace should follow the same bone as the loading diamond avatar. unless this is being done globally and not locally?

[tribal meadow]

I was using a bunch of modified jetdog scripts to have things synced in my world....without having to re-invent the wheel and start from scratch does anyone know what I need to modify in these scripts to get them working again? This update is causing me hours and hours of work to fix :(

[fiery yoke]

Its been requested here: https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback/p/allow-parenting-objects-to-player-bones-player-position-and-player-tracking-data

[fiery yoke]

There is workarounds, but no official event. Thats a common reoccuring theme btw that you will have to get used to :^) VRChat is a big project, so development is slow, and so QoL stuff like those events is quite low on the priority list I imagine.

[candid wolf]

Not all avatars have the same bone rotation, read further up. to "fix" that, I'm storing the offset of the avatars as soon as it's equipped

However, if the avatar is changed, and the new avatar has a different offset, there's no real way to check that

[fiery yoke]

Unity does not define a standard for bone rotations, so there exists no universal way to do what Luna is trying to do. Unity is meant for game developers, who define their own standard. So VRChat sort of creates a problem, by not defining a standard all users have to follow. Which is good because it doesnt force you to do something a certain way, but it means that attaching stuff, without knowing the default rotation of the bone is impossible, without making certain assumptions.

[candid wolf]

Pretty much 😄

[fiery yoke]

And you can kinda detect avatar changes

The distances between two bones will usually not be the exact same, when switching avatars, so thats an easy way to check for avatar change

[candid wolf]

Being able to attach to bones directly would "fix" that, since the unity hierarchy somehow solves that rotational issue, not to mention solve the issue of synchronizing stuff

cause you wouldn't have to update the object's position and rotation in the update loop on every frame

[fiery yoke]

There is a pretty clever way of synchronizing that, which is just synchronizing the offset and to which bone an object is attached. You dont need to synchronize the position and rotation at all that way.

[candid wolf]

@fiery yoke the issue with that approach though, is the fact that it needs to be bones that aren't used by full body IK, cause I believe the distance varies when you move them around

[fiery yoke]

The distance between two consecutive bones should never change

Unless you have floppy bones 😅

[candid wolf]

¯_(ツ)_/¯

Also on the topic of standardization, technically unity already provides a standard rig

[fiery yoke]

No it does not

[candid wolf]

the "humanoid" rig

[fiery yoke]

Believe me. I have looked rigorously into Unitys Humanoid system. It does not define a standard for bone rotations

It simply requires you that certain bones exist in a certain hierarchical order

[candid wolf]

I wasn't talking about bone rotations...

Was talking about rig layout

[fiery yoke]

Ohh well yeah, but that doesnt help you at all. At least not with your problem.

[candid wolf]

I mean the biggest issue is just not being able to access the hierarchy

cause here's the fun part

if I just attach the thing to the avatar's neck bone in the hierarchy

it just works

(╯°□°）╯︵ ┻━┻

[fleet bramble]

┬──┬ ノ( ゜-゜ノ) There you go

[candid wolf]

Thanks vrcbot

(Talking about orientation by the way)

[fiery yoke]

Well yeah, when you parent something in Unity, unity calculates what position the object needs to be in locally, such that the global position stays the same.

Its Matrix math, you can reproduce the same effect, without parenting.

In fact Unity has components called Constraints. One of them is the parent constraints. It makes an object act, as if it were parented to the constrained object.

[candid wolf]

I mean, you'd think that if a bone is pointing upwards that when you reference it's rotation, it'll be y-up

[fiery yoke]

But as for VRChat, the player objects such as the player armature are protected for a reason

[fiery yoke]

Well how do you define up? :P

Unity defines up as y+ sure. But an armature can define up to be anything

Thats why Im saying that Unity does not force a standard on you. As a developer you usually decide on your own standard. But because VRChat is UGC based and does not define a standard themselves, youre kinda f'ed.

Again there is workarounds, but all of them are based on assumptions. Assumptions that are usually reasonable, but may be broken. But its usually good enough

[candid wolf]

VRC ".attachToBone()" when?

[fiery yoke]

Like for example one such assumption would be that your eyes are pointed "forward"

[candid wolf]

Speaking of weird things, I kinda wonder sync wise

When you pick up an object, it syncs better than when it's attached to a bone (through positional updating)

kinda wonder what's causing that

[fiery yoke]

Because VRChat gives that a higher priority

[candid wolf]

Guessing it's underwater stuff we can't define ourselves?

[fiery yoke]

pretty much

[candid wolf]

Welp, time to shelf this project as "good enough for now" and start updating my board game world to the latest version of udon

[hushed silo]

I'm going to ask a dumb question here, but my friends and I are working on a more optimized sort of map, and i'm wondering, does SDK3 versus SDK2 have an impact in terms of performance, for equivalent functions (collider toggles, seat toggles)? Or is it basically the same?

Thanks in advance.

[dapper lion]

im like 90% sure they are equal, its just udon/sdk3 allows you to do more than sdk2

#world-optimization might attract people with a solider answer

[hushed silo]

Oh, thank you, i didn't realize that was a channel!

I'll repeat my question over there as well.

[craggy harbor]

Hi guys, I have a question about player tags.
So I start with Setting the local player tag like this

Networking.Localplayer.SetPlayerTag("Role", "Cook");

Later when I was trying to access the tagValue, I used this function:

Networking.Localplayer.GetPlayerTag("Role");

And it doesn't return me the tagValue "Cook". Did I misunderstand the system?

[stark adder]

Yea it works like that

Prolly doing something wrong somewhere ?

Are you sure you're setting the tag ? maybe hidden behind some if() or something ?

@craggy harbor

[craggy harbor]

Is this function only working for the owner of the object?

[stark adder]

Also obviously it only stays while player is in instance then it gets cleared and it is NOT Global

If you use Networking.LocalPlayer.SetTag("XX", "XY");
then on remote client you try remotePlayer.GetTag("XX") it will == to ""

[craggy harbor]

Oh that's understandable.

[stark adder]

I wish the tags were global but also I don't.. Cause if tehy're global hackers can mess with them for everyone

[craggy harbor]

oh btw

I was testing with multi-client way.

[stark adder]

Unless VRChat protects it which.. Yea VRChat and protecting something against hackers ?

[craggy harbor]

could this mess up with the PlayerAPI check? as technically the 2 clients are the same player account

[stark adder]

not sure.. I know some things do mess up when LocalTesting

Not sure if this is one of them

I know I had giant problems with VRCStations when Local Testing but when Uploaded they all work as expected

[craggy harbor]

👍 I see

Thank you for your information. I will do some last check, then I will upload and test it with my friend online see if the problem still exist.

[hushed gazelle]

Is there a proper way to detect when a NavMeshAgent has arrived at its set destination?

[craggy harbor]

I think agent.remainingDistance or agent.pathStatus==NavMeshPathStatus.complete can tell if the agent has arrived or not.

[hushed gazelle]

Ahh, cheers.

[craggy harbor]

About the SendCustomNetworkEvent() function, if I choose the target to be all, is there still a chance that this event will not be invoked on someone's end?

[grand temple]

Not that I'm aware of. It's very reliable

[cold raft]

i am pretty sure vrchat does not garantee dilivery of the event but it should work very reliable indeed

[craggy harbor]

🤔 hmmm, then it's very interesting. caz I'm testing with 2 clients and the second client just never invoke the event.

meanwhile the first client always get event triggered.

[hushed gazelle]

Is there a graceful way to tell a NavMeshAgent to turn to face a certain direction, or should I just force it by setting the Transform's rotation?

[craggy harbor]

I don't think there's such a function, so you do have manually tweak the rotation of the transform. Worse case you might also want to code a customized "LookAt" function instead of using the unity built-in "Transform.LookAt()" function, as it can only promise the forward point towards the desire location, but the other rotation parameters might just be a mess. (like imagine a tank aiming at the target perfectly but the tank is upside-down, etc)

[hushed gazelle]

That's fine. All I'm looking to achieve is "go here, stop, face this direction".

[grand temple]

Is the event you're calling public?

Or is the object instantiated?

[craggy harbor]

The object is in the game by the scene setup, and it's a public function.

[grand temple]

If there's ever a case where an event may have a chance of not going through, it's going to be because of too much load on the network. But even then, I've seen it just queue up and wait until it's ready. Especially with two clients, it should still work.

So more likely is that something is just not set up correctly

[craggy harbor]

🤔 I see

then there's probably something else went wrong

[grand temple]

Maybe you've got logic inside that event that causes it to stop?

[craggy harbor]

Is the tagValue local only?

[grand temple]

What, player tags? Yes

Those are not synced

[craggy harbor]

like, if I set player0 some tagValue to 111, then I try to read it from player1, will I be able to read it as 111?

🤔 I seee

[fading cipher]

I know you need to check if inputdrop is activated for vive users, since drop is the event that is registered when a vive user presses their grip button

Is there any sort of weirdness like that for the Use button, or is it the same across devices?

[grand temple]

Depends entirely on what you want to get out of it

Input use will be triggered when a vive user grabs a pickup, because their trigger is what they use for pickups

[fading cipher]

Ah, so it's essentially inverted for vive then

[grand temple]

No, it's not inverted. It's combined

[chilly crater]

If I grab ownership to apply force to a rigidbody and return ownership immediately afterward, will that hurt me in any way?

[fading cipher]

in order to do something like that you'll need to set up a custom script that distributes one from a list of synced objects to each player that joins, then you can tell a player to set their synced object's variables and other people can read it from there

[craggy harbor]

Ya that's a good point, I just didn't know the tagValue is local. I'm working on it now.

[fading cipher]

We do that in our world thanks to an amazing set of scripts my friend wrote; it's the backbone for all our custom networking

[grand temple]

On vrcprefabs.com/browse there's a prefab called "simple object pool" that hands out a unique object to each player

[chilly crater]

It makes it sooo much easier.

[craggy harbor]

It is a bit too late for me as I've already created the entire system that does it, but thank you for the information, I will check it out if I got stuck again and consider about redo it.

[fading cipher]

So if I'm checking to see if a Vive player grabs an object I will check their InputUse since that's what's called when they press the grip button, and when checking to see if a vive user has used an object, I'd check for InputDrop? That's why I suggested it's inverted

Or are you saying input use is used for both "point and click" UI interactions and for grabbing an object, duh

That didn't really align in my head at first lol

[grand temple]

The trigger activates input use and input grab. The grip button activates inputdrop

[fading cipher]

oh yeah drop that's what I meant

Okay

Trigger is grab and use, but for Vive my interpretation of their drop is their grip, so their grip doesn't do what grip does for non-vive users

That's why I was confused xD I didn't want to set up a trigger based on use if it would trigger grab stuff too

[grand temple]

Yeah, because the grip is terrible for holding a long time so it's used to drop instead

[fading cipher]

But my grab for them is on drop

I'm very happy we can reliably check their system in order to verify which input event to use

[grand temple]

Hahahaa

Nope

Reverb g2 still reports as vive despite having an oculus-like control scheme 🙃

[fading cipher]

really?

omg you're right

THAT'S why my fucking controllers were vive holograms the other day

wow that sucks

I use knuckles with g2, I was very confused as to why I was seeing vive wands according to VRC lol

[grand temple]

Eh, the controller hologram doesn't matter I think

[fading cipher]

I hope not, it just confused me at first

[grand temple]

What matters is lastusedinputmethod. If you're using index controllers they should report correctly

[fading cipher]

Yeah that's what I've been doing after verifying many months ago that that only reports the correct enum if you're doing it in late update T.T

[grand temple]

Hmm? Im not so sure about that

What's the difference?

[fading cipher]

I had Momo working with me nearly live, I have pictures I think in this channel from when I was troubleshooting it

When I was checking for vive users, I was just getting the wrong value altogether when I checked it in regular update

[grand temple]

What did you get?

[fading cipher]

or no

I got the right values I think, but reading the value and comparing it to the enum value was returning false

[grand temple]

Oh yeah, enum comparisons are a bit odd. I think if you cast to int first then compare to an int that should work

[fading cipher]

When I logged it, it alternated between saying I was "4" and "vive", but when I compared against it in update later down the line, it always thought comparing it to either 4 or inputmethod.vive was false

I fixed it by running the actual bool setting in late update

if all it took was an int cast, that's depressing xD

https://i.imgur.com/IMY5AS1.png

[grand temple]

Not sure how late update would change that, weird

[fading cipher]

Same, it was a momo suggested fix lol

#udon-general message

that's the time around it happening

[grand temple]

Lol I said basically the same thing as momo

[fading cipher]

derp

But probably a good thing for you to be aware of if you encounter an issue like that where logging the input method gives a value, but comparing against it is always false

[hushed gazelle]

Got another NavMeshAgent question; Is there a proper way to detect when the Agent is climbing stairs? I thought VelocityY might do it, but it's hugging the stair mesh despite a sloped box collider covering them.

[chilly crater]

This is in relation to bonepositioning, Avatars require headbones, right?

And if it doesn't have them, it defaults to (0,0,0), right?

[fading cipher]

Any bones a player doesn't have will default to the origin, that's for sure

I'm pretty sure avatars require headbones, yes

[cunning mist]

If you're just wanting the head position, you can instead do GetTrackingData and select Head. That get's the position of the headset rather than the headbone and would likely get you what you need.

I'm trying to parent something to the head, and some testers complained that it was flying off at weird angles.

[cunning mist]

I would do GetTrackingData in that case.

Locally the head bone is scaled down to 0 anyway

[chilly crater]

That's what I'm doing. I'm trying to figure out if I did something wrong or if this is some FBT trickery.

Or they were ignoring the clearly visible settings panel for the parent offset

Which I should probably increase from .5 to .75 +/-

Should probably throw in a if localplayer isn't owner, not pickupable

[cunning mist]

If it's synced than yeah lol

Gave everyone their own CombatSystem armor, holster rig, and pistol. People were able to yoink guns, and that was probably messing with the lateupdate scripts.

[fiery yoke]

VRChat still allows Generic Avatars. Generic avatars dont even need to have a humanoid rig at all. So you can never say for certain that a bone must exist

[chilly crater]

oof viva la headtrackingdata!

Even though you can set ownership of an item without being the actual owner, is it still good practice to have the original owner give it to you?

I have an OnOwnershipTransferred call that will have the owner of the children of the object that caused this call to transfer ownership to the new owner.

What's a good vertex count to aim for in a world?

I actually haven't thought once about that, and I'm watching my enviro modeling volunteer rn and I have no idea what limit to give him xD

[cold raft]

i think there is some number on the vrc website

oh those are numbers for quest

Oh god someone pelase help, ive been trying to fix my sdk for hours now.
someone tell me what the f*ck is TMPro and why does my sdk keep saying it "couldnt be found"
im at my limit

ive uninstalled/removed udon AND vrcsdk and reinstred both new and old versions. including the .meta files and yet it gives me the same error evey danm time

...should i put this in User-Support insead?

[twin hedge]

Hello. I'm new to Udon. So, I've set up the udon for the mirror and it works. Now I'm trying to figure out how to set up the udon for chairs, but it looks like I need to set up in the same network or something?

[ionic brook]

how does object sync work?

the udon behavior doesnt have the option to have local and global sync options anymore

[twin hedge]

Just local

[ionic brook]

i see they brought back VRC_Object sync

is that

is that no longer deprecated?

[floral dove]

It's a new one: https://docs.vrchat.com/docs/network-components#vrc-object-sync

[twin hedge]

I forgot to add one thing. I can't add the 'interact' thing to another network for chair collider, but I know I'm doing something wrong cuz I'm new lol

[ionic brook]

ugh

[twin hedge]

lol

[ionic brook]

@hidden marten

shut up

[twin hedge]

:0

it's just a bot doing its job

[ionic brook]

so you're telling me i have to add vrc object sync to all of my objects now?

this is gonna ssssuuuccckkk!

each car in my world has removable parts off it

[twin hedge]

rip

[ionic brook]

this is half od the heirarchy for ONE CAR

[floral dove]

You want to limit the number of synced objects for best performance. Wherever possible, sync a single object and drive the rest of them locally.

[ionic brook]

It sure would've been nice if VRC Object sync was automatically added to objects that had global sync checked in the udon behavior component

[floral dove]

You don't want to sync all those objects.

[ionic brook]

lmao

so you're telling me

if i apply the vrc object sync to the parent of all of those car parts

[floral dove]

Sync the parent object

[ionic brook]

i wont have to do it for each individual mart?

[floral dove]

Right

[ionic brook]

please tell me you're rught
