udon-general

[grand temple]

What you're looking for is rendersettings.skybox.setcolor

or set the material

[rain hearth]

hmm, they dont appear in node search

[grand temple]

huh?

[rain hearth]

okay, was looking for something like RenderSettings.skybox

the "get skybox" is not showing up either

[grand temple]

it's just a material, so you want set skybox anyway

then you can have some public material variables

[rain hearth]

hmm, well still cant do anything, Udon does give me any results even when I type in "sky"

[grand temple]

you have to search for rendersettings first

or if you're ever unsure what category something is in, you can do tab to do a full search

[rain hearth]

okay, starting to make sense, I see them now

[rain hearth]

hmm, cant I just drag and drop the material into the graph editor? Not sure what I need after get skybox

[grand temple]

no, use set skybox

and make a new material variable in the window on the left

drag that into the "set skybox" node

and then make that variable public so that it shows up in the inspector of the udonbehaviour, at which point you can drag it in

[rain hearth]

okay, this is what I got so far

i know I might be missing some logic, so it can switch back to day, and night again for each interact

[grand temple]

yeah, you can have separate buttons for each setting but they can be the same udon source

right now you have it named "nightmaterial" which implies that you're setting it to night, but there's no reason that you can't use the exact same source but plug in a day material

you'll want a public color variable to plug into the fogcolor so you can adjust that though

[rain hearth]

okay, so just make a seperate button with all the variables swapped places and it should be good?

the other game object variables are the objects that contain their own respective directional light and post-process volume

oops, gotta move the interact to the start

[plush stump]

Which event should I use for a vr controller input? Like clicking A/B button send a custom event to my program.

[quaint trellis]

I'm trying to have an animation increase with 1 frame whenever I press a button. If I press it now, it only goes to frame one and not further. This is my udon graph rn.

i've been able to find that the issue is in the GetInteger node. It doesn't seem to be getting the integer at all, so the addition node is constantly adding 1 and 0. is there a way to get the correct integer, or maybe avoid using the GetInteger node entirely?

[quaint trellis]

more testing! it seems i was wrong, and the addition node does not work as expected. even if i do 3 + 1, which is 4, it only goes to frame one. It seems like the node always returns 1. this seems to suggest that either I'm using the addition node wrong, or it is broken.

[mighty fjord]

How are you using an integer to control what frame the animation is on? What's the animator controller setup like?

I'd use a float which is used as the normalized time instead

[fiery yoke]

Or it is outputting the correct result but you're using the result wrong. The Debug.Log node is your friend inthis case.

[quaint trellis]

i used the log, and it does ouput the correct int. so it is counting up. however, for some reason it's not setting the int "Frame" of the animation. however, if i manually set the int it needs to change to (by changing value in setinteger) it does go to the correct frame.
that's also why I can't use a float, as you can't do "float equals x", only greater/less than.

[quaint trellis]

this is my animator tab. every frame has a transition. if Frame=1, it goes to frame one etc. I know it's jank, but this was the only I was able to get it to work correctly with my limited knowledge.

[mighty fjord]

By the looks of things, it's most likely getting stuck on the first state after the initial one it goes to. Try playing the scene, clicking the object with the animator on it, and then going to the animator tab to see which state it's on, and then try to change the int parameter manually in the animator.

However, I'd recommend driving the normalized time of a state using a float parameter instead

[quaint trellis]

how can i click on the object? when i press play, i can't interact with anything in the game window

[mighty fjord]

Once you press play, it prompts you into game view, but you can easily just switch back to the regular scene view or hierarchy

[viscid reef]

that looks like because your initial state can only go to 1 of the subsequent state

you should be transiting from the any state node, not the default node 0 you have there

would definitely recommend what Nestorboy said and use a float with normalized time or a blend tree instead though

[quaint trellis]

thank you! it worked! i'm very new to vrchat development and unity in general, so i completely overlooked that.

[quaint trellis]

how would i go about doing this?

[mighty fjord]

If you click on an animator controller state, you can tick the 'Parameter' option and select a float parameter from the animator controller. The float will be used to sample a point in the animation, 0 is the very start of it, and 1 is the end.
So with this in mind, you can do some simple math to sample a given frame instead (frameIndex / frameCount - 1), but make sure it outputs a float so that you can use it to set the float parameter.

[quaint trellis]

aight, imma try that

[mighty fjord]

E.g: Animation with 9 frames, and I want to sample the middle frame, 4 (since the frame indexing starts at 0 and goes to 8). Now if we do the math it's 4 / 9 - 1 = 4 / 8 = 0.5, meaning the float is right between 0 and 1, in the middle.

[fiery yoke]

Most likely your transition logic is just wrong. Statemachines can be quite tricky.

[wind atlas]

Just some shower thought, but maybe someone knows: Can you upload a collider on an avatar and then detect it in an Udon world?

I know you are supposed to use player data and stuff, but it would be fun if you can access the transform directly.

[dapper lion]

yes. actually

for some reason - you can

[wind atlas]

Really? So I can, for example, impale people's limbs more accurately with this?

[dapper lion]

um. possibly

you would have to be very clever about it

[wind atlas]

Damn, that's interesting. Probably not as useful for most cases, so I'll keep it in the back of my mind for now.

[dapper lion]

probs footsteps and collider audio. like i discovered this 5ish days ago when someone had a flight avatar and was walking on my marimba and their colliders were triggering the marimba sounds

or avatar to world prop systems

actually.... theres a lot of stuff you could do with this

[wind atlas]

A belt system to attach stuff directly to the avatar too. Although people need an avatar with a collider for all this to work.

[dapper lion]

correct. at this point, you would use bone positions

[mighty fjord]

The only thing avatar colliders allow for is collision events more or less, but I believe that will be patched in the future

[dapper lion]

physbones right?

[mighty fjord]

What?

I believe you're really limited to what you can actually extract from the collision though

[broken bear]

Can udon read the unity version used to upload the world package? Or better, the avatar package ?

[floral dove]

no, Udon has no access to that info

[restive veldt]

How do i add interaction to an object? stuffs changed

in a UdonBehavior component

[grand temple]

add an interact event

the white arrow that comes off of it is called "flow" and that determines what happens

you can plug flow into other nodes like gameobject set active

and you can chain nodes together to do multiple things in a specific order

[restive veldt]

i have though

nothing came up in the editor after adding that

[grand temple]

what do you mean by editor? Like the main udon graph window, or the inspector on the right?

[restive veldt]

i added the Interact event to the udonbehavior through the Udon editor, compiled/saved, and then went back to the inspector to check and see if i had settings for interaction on the udonbehavior. But there's nothing there.

[grand temple]

That's correct, you don't use the inspector to determine what happens with the interact

you need to add more nodes to the udon graph and connect the flow (white lines/arrows) from interact into the nodes that you want

[restive veldt]

yes

but

Stuff like the text displayed

When you hover over it

[grand temple]

If the interact isn't connected to anything, then it will not be compiled into the final script. If it's not in the final script, then it has no way of knowing that it exists, so it won't allow you to change the interact text

as soon as you make the interact do something, it will be compiled and the inspector will pick up on that and allow you to change interact text

[magic pelican]

How do I get this toggle to toggle for all players instead of just the individual?

[floral dove]

you can learn how Networking works in Udon here: https://docs.vrchat.com/docs/udon-networking
For this graph, I'd recommend adding a synced bool variable, and using an OnVariableChange event to set the GameObject to active or inactive based on the newValue of that variable.

[autumn birch]

Does anyone have a basic "on collision with player", "do this" script I could have?

[hallow sable]

how exactly do I use VRCInstantiate? can't find out how

[autumn birch]

Do I need to add something to this for it to work?

[rotund wolf]

would this be the right thing to do if i wanted to press a button and have me teleport somewhere?'

[grand temple]

No, what you want is VRCPlayerApi.teleportto. plug in networking.localplayer and some position, which you can get from a transform

[olive jay]

Heyo, just trying to wrap my head around an idea. What would be the best way to detect a held object being shaken. Would it just be getting the velocity from a rigidbody component from the object? Or is there another way I could go about it?

[shell ingot]

is any extra code required for this to work

[grand temple]

That would work, but the block is unnecessary and the settings are definitely not what you want

if you increase voice range you want to decrease voice gain

with 100 range you'd probably want about 5 gain

[shell ingot]

why would you decrease gain?

[grand temple]

because when you increase range, it gets louder

increasing gain also makes it louder

so you'd want to decrease gain to counter-act it

[shell ingot]

@grand temple one last thing could I also apply this to a moving object

[grand temple]

yes, as long as it has a rigidbody

[shell ingot]

such as a holable microphone

[grand temple]

you'll have to make the collider pretty big because the collider for other players is just a small sphere at the feet

so while holding the microphone you'd have to make sure it's big enough to reach the feet

[shell ingot]

so thats why it wasn't working

thanks

[rotund wolf]

is this in the udon graph cause i dont see it in the udon graph

[grand temple]

yes, you'll need to navigate through categories. The first is playerapi, you search for that and hit enter. Then inside that category you search for teleportto

if you're ever unsure what category something is in, you can do a full search with tab and just search for it directly, in this case teleportto

[rotund wolf]

is that good?

[grand temple]

yep, now plug in whatever position you want

[rotund wolf]

cause when i click the button it keeps teleporitng me to spawn

rather than the place i wanna go to

[grand temple]

yes, because you're not defining a location

oh actually you are giving a position but it's -140 on the Y axis so it's probably causing you to respawn

[rotund wolf]

it's below the map tho

well below spawn at least

[grand temple]

then you'll have to lower the respawn height of the scene descriptor

[rotund wolf]

wouldn't that lower the spawn at the start of the world tho?
cause my spawn ponit is at y=0
and the place i wanna teleport to is below the map at y=-140

[grand temple]

changing the respawn height doesn't change the spawn position

[rotund wolf]

why would i have to increase spawn height tho?
(its originally at -100 btw)

[grand temple]

the respawn height means that if you fall below it, you'll respawn

your respawn height is -100

the place you want to go is -140

-140 is less than -100

[rotund wolf]

ah i see

so if fall < -100, it'll respawn

i see

at this point it's spawning me off the map lol

[grand temple]

do you mean actual spawning or do you mean when you want to teleport?

[rotund wolf]

i meant when i want to teleport
spawn's perfectly fine
it's just that when i teleport, i end up respawning for some odd reason

[grand temple]

the position that you put in is probably not correct then

[rotund wolf]

when i teleport i should end up below the map

instead i respawn

[grand temple]

add a public transform variable to the graph

drag that into the graph

then get transform.position

and plug that into the teleport location

then create a new object to be the "teleport point" and position it where you want them to teleport to

then plug the teleport point into the slot in the udonbehaviour inspector

[rotund wolf]

do i still need the getlocalplayer api thing?

[grand temple]

yes

[rotund wolf]

this is what i have

idk if its right

from what ive noticed

it teleported me to the exact same spot i was standing on

i think i need an end position somehow

[grand temple]

you're not specifying what transform you want to get the position of

which means that it will get the position of the object that this udonbehaviour is running on

[rotund wolf]

i plugged the transform into the teleport location

[rotund wolf]

and it still did the same thing

how do i specify the tranformation of the position

[hallow iris]

mhhh when a value reaches 0 a player would be sit onto a station that is supposed to be picked up but for that i would need a colider that is enabled but for god sake idk why trough the graph the capsule collider is not getting aktivaded in any way

it wont stop ya from moving trough nor is it posible to pick it up

am i just overlooking something or does the set enable just doesnt work that well <.<

[north temple]

Is there any solution how the kicking player in the world? without placing the portal.

[cold raft]

no

[north temple]

Okay, thx

[hallow iris]

I mean, force crashing him would be a thing

By making an event that sends a custem event to it self

Making it an endless self repeating event

Which instandly crashes

[steel remnant]

I've just started poking at UdonSharp, and I keep seeing tutorials with VSCode "suggestions" for VRC functions/types, I don't have these, although I do of course have C# intellisense.

How would I go about getting these?

Hm... seems like I have bigger issues. 😅
I'll hammer this a bit, hopefully that's all.

[wind atlas]

Even if you are using vscode, once you have a proper project file generated by Unity, it should you show everything.

[steel remnant]

It shows monobehaviour stuff, but no Udon.

Here's the project folders.

Got the latest U# and VRCSDK too, so shouldn't be that. 🤔

(and using Unity 2019.4.31)

[wind atlas]

Do you have the namespace VRC.SDKBase imported?

[steel remnant]

Yes.

[wind atlas]

I haven't used vscode in a while, so I'm afraid I don't know the issue.

Make sure whatever extension you are using is importing all the project file.

I remember omnisharp had a log for that.

[steel remnant]

Omnisharp was whining about files not being loaded earlier, but the messages went away.

[wind atlas]

Try restarting it and see what it logs.

[steel remnant]

Restarting VSCode and just OmniSharp doesn't send any errors any more. 🤷‍♂️

I'll try making another project real quick, just to sanity check.

bah

[wind atlas]

Have you read this? https://code.visualstudio.com/docs/other/unity

[steel remnant]

Nope, I'll give it a read, thanks. 😅

[wind atlas]

Specifically this: https://code.visualstudio.com/docs/other/unity#_enabling-code-completion-for-recent-versions-of-unity

Hope it might help a bit.

[steel remnant]

Hopefully, thanks for the help either way. 🙏

Yea no, didn't fix it.
It's weird, I get Unity code completion, but nothing from VRC. :/

[stable venture]

Does Udon support making external http requests?

[fiery yoke]

Nope. And probably not any time soon. The only HTTP requests that are not made by the client itself directly are those coming from Video Players.

[steel remnant]

Found what I was missing. xD

There's a prompt that shows up when you open a .cs script where you have to select the .sln, but it just looks like a search bar, and I instinctively closed it every time. 😂

I am big dumb

[scarlet lake]

Anyone ever had their vrchat sdk stuck in some udonsharp compile loop that won't let them launch? I've tried recompiling manually and restarting everything, it just beeps and won't launch vrchat when I click build test.

It got hung up somewhere between testing in unity game view and trying to launch a test build through the sdk.

[scarlet lake]

figured it out, had recently imported a c# editor script to do some batch renaming and udonsharp didnt like it being there

[livid skiff]

I'm attempting to toggle a GameObject on and off when a player enters/exits a trigger zone which is working however this is triggered for all users in the instance. How can I make this local?

I tried setting up two separate scripts, one to send a custom event on trigger enter, one on trigger exit and have the above script activated by custom event. Same result, it still is triggering for everyone.

[green schooner]

Heyo, sorry if this is a stupid question but is anyone else having issues with networked events in U# after using the newest SDK and 2019.4.31f1 Unity?

[night viper]

You will need to add a branch with Get Is Local. This will allow the flow to continue only if the local player (you) is the one entering the collider. Since OnPlayerTriggerEnter detects other´s people collider as well.

[livid skiff]

Thank you very much for this, I figured it was something like this but wasn't sure how to set it up.

Edit: that works, thanks again.

[scarlet lake]

bruh]

😔

I made this so that when I click on the off button it will disappear and make the on button appear, along with that the mirror will be activated.

My problem right now is that WindowMirror also activates BedMirrorFront for some reason and I'm not sure how to fix this so that they are separated so they can be clicked individually

I could fix quickly this by having them all in different scripts but I want them all to be in one

Is there a way to resolve this?

[fiery yoke]

The second if statement uses WindowMirror instead of BedMirrorFront. Pretty sure thats not intended :P

[scarlet lake]

OH

THANK YOU

xD

I am blind af ;_;

[fiery yoke]

Dont worry, happens to the best lul

[scarlet lake]

It still doesn't work for some reason 😔 I have an idea though

[rotund wolf]

any good tutorials on player teleportation using udon in worlds?

[shell ingot]

would this work to change the integer for an animation

[autumn birch]

Is there an easier way to make these scripts? Because I can't even manage a basic script...

and my failed attempt seems to have broken my controller

and now I can't see any states whatsoever..

[verbal lance]

is there any way to create a new material at runtime with udonsharp?

[dawn forge]

I am wanting to pipe all data/methods to a single script called "Network Controller" which will exchange data to everyone's "Network Controller" rather than each object's scripts doing so. Is this a good design? The Network Controller would be the only continuous sync'd object.

[shut patrol]

I already did something similar, but i came to the conclusion that there is no need to manually synchronize constantly updated data, such as the position and rotation of objects, as this can severely impact performance. But if you need reliable network messaging you can try my utility, it also includes binary serialization https://github.com/Xytabich/UNet

[scarlet lake]

I dont know if its within udon peramiters but I cant run and jump anymore in VRChat, Why is this?

[hallow iris]

Depending on the World your in

[devout sky]

Heya, the build tab for my project is blank, any ideas why that is?

I have the latest version of the SDK3

[scarlet lake]

It's every world I am in, I do not know the reason or the demoniator I just wanna run and jump ;~;

[hallow iris]

Messed to much with clients eventuelly? <-<

[wind atlas]

@autumn birch Try to remove the spaces from the script name. It needs to look exactly like in the class name.

[tight pike]

Does anybody know is it possible to make a world which remember some variables for each individual players even after the world session/instance closed?
Or are there any official statement of them planning to make that available in the future?

[west mural]

no, yes

[wind atlas]

@tight pike There are plans, I don't remember the schedule, but eventually we are supposed to get data persistence.

@tight pike I heard it's kinda possible to do that with video players (maybe). I personally find that interesting, but it would require you to handle your own server and make some weird serialization of data or something.
But nothing that's actually intended.

[verbal lance]

udon/udonsharp has no support for new Material() right?

[barren crane]

I’m having some trouble with my world I’m trying to build test it and it keeps saying”All #U compiler errors have to be fixed”

[wind atlas]

@verbal lance Doesn't look like it has. But doesn't every renderer have a material instance anyway if you want to change things?

[verbal lance]

that's what I thought but SetTexture doesn't seem to work

not that the ability to create materials at runtime shrinks my work flow that much since I can't make new Render Textures at run time either

[fiery yoke]

@verbal lance what exactly is your goal here?

[verbal lance]

The ability to have a prefab that uses a screen with a render texture without having to create a new render texture and material every time i add a instance of the prefab to the scene

unless I am missing something and unity lets me do this by default

actually a editor script would work fine and I am overcomplicating things lmao I just realized

[fiery yoke]

Hmm I see...well having dynamically added screens is...very exotic.

[verbal lance]

It is just a very roundabout workflow right now

[wind atlas]

Yeah, if it's just about placing prefabs, then you are not limited by Udon and can do it with editor scripts.

At runtime you'd probably need to make a pool of render textures or something.

[verbal lance]

yeah I'll just do it with a editor script

probably cleaner anyway lol

[verbal lance]

does GetTrackingData(VRCPlayerApi.TrackingDataType.Head).position give me the avatar head position or just head tracking data based from 0, 0 because from testing it seems to be the latter in which case how am I supposed to offset it?

[fiery yoke]

Tracking Data always gives you the position/rotation in world space. However you can make it relative to the player origin by using TrackingDataType.Origin. then just subtract the origin position from the head position.

[verbal lance]

well I am trying to set something to the player's head position in world space

every example i can find just does

private void PostLateUpdate()
{
    var trackingData = playerLocal.GetTrackingData(VRCPlayerApi.TrackingDataType.Head);
    transform.SetPositionAndRotation(trackingData.position, trackingData.rotation);
}

but that puts it somewhere in the air away from the player (still following the movements)

I'll try doing the origin thing i guess

[dapper lion]

its been forever since ive messed with bone attachment scripting but a common issue was that people would use models that are offset as an fbx. which would translate in game

[verbal lance]

I am using a primitive so that can't be the case

[dapper lion]

also - “PostLateUpdate()”.... ive never seen any example using transforms on the postlate

[verbal lance]

without a parent

[dapper lion]

so the cube is being offset?

aw man. i wish i was at my pc cus i have sooo many bone tracking scripts you could look at

but that snippit you sent looks correct. i remember using an offset before but theres ways to not even need one

[verbal lance]

oooookay something is fucky holdon

[light fjord]

anyone else experiences object sync delay? upwards of 3 + seconds even if all people have similar delay?

[sinful sentinel]

hello everyone, just got into this yesterday (HP Reverb G2). are there any good sites or apps for browsing Worlds or interest groups?

[verbal lance]

I am at a loss, I put the cube inside a empty object and moved that instead and it works fine lmao

[dapper lion]

yes. this can be helped by using a local sync using avatar position but hoping object sync will get better soon

[dapper lion]

are you doing any math for the new game object?

or a different avatar tested

[verbal lance]

well for the cube i was touching the rotation but not the position

for the parent object i added i am only running the script i send earlier

and that works now

[scarlet lake]

Does anyone know why my pickups are jittering around when I hold them?

They also don't move around properly when I rotate them and such with IOPJKL

[scarlet lake]

I fixed it, it was due to the origin point I had set in blender

[toxic glen]

I have a question. I'm trying to make a gun shoot, I've found a tutorial for shooting physical objects, but what do I do if i want it to be hitscan?

Im using Graph btw

[wind atlas]

@toxic glen That would be done with a Raycast. I'm pretty sure there are some unity tutorials on that or hitscan weapons in general.

This one seems good: https://www.youtube.com/watch?v=THnivyG0Mvo

[toxic glen]

Yes, i realize its done with raycast, but how would i code that in UdonGraph

[slim hound]

Everything in graph has the similar if not identical names to what is shown in the video

When in the graph you can hit tab to do a global search

[toxic glen]

Cool, thanks

👍

[slim hound]

You would want physics > raycast if searching normally though

And from there you can drag and drop from the node points to bring up search windows that specifically shows what's available for any given function

As an example from the raycast hitInfo you can drag and then search for "get" to get the collider

[toxic glen]

Im not entirely sure how to link it all up together. So i have my raycast seeing the camera position and forward, and thats pretty much it. Im not sure where to go from here.

https://prnt.sc/1usgfcr

(the on pickup use down goes to a block and then goes to a sound to play)

[slim hound]

In the dropdown change it to this

Or any other if you need those functions

[toxic glen]

So, like this? https://prnt.sc/1usgu4v

[slim hound]

You don't need the RaycastHit going to the input of the raycast

And from the raycast node you want to use the output hitInfo from there

[toxic glen]

Ah, because the Raycast box has a hit info coming out of it, i see. i see.

Then i get collider of whatever it sees

[slim hound]

Yeah or any other data you want to get from the raycast

[undone moon]

Is there a good way of getting the player VRcontroller inputs in udon or udonSharp?

[toxic glen]

Ok, so then how do i test to see if this is working? Like, make an object light up when hit?

[slim hound]

Similar to in that video that was posted you could make it so it logs the name of whatever is hit

[toxic glen]

Gotcha

[wind atlas]

Have you seen this? https://docs.vrchat.com/docs/input-events

[toxic glen]

Now lets say i want targets to shoot at that react to being hit. How do i make another object do something when hit?

[undone moon]

Yeah but that confused me a little. It doesn't seem Show which player triggered those events, and I though I might have to have the player grab the object, and use the object, while I want the player to be able to trigger things a lot more remotely

[wind atlas]

You cannot access inputs from other clients.

You have to send the event (whatever you are doing) to all the other clients so they can execute it on their side.

[undone moon]

I want to make a skateboard like thing. Were the The skate board is toggled from clicking both triggers, and is steered by grabbing at the air and moving your arms.

[undone moon]

So I basically use the input events locally and sync up the results afterward?

[wind atlas]

Basically, yes. A simple way would be to just use "SendCustomNetworkEvent" as soon as the player hits both triggers in your example.

[wind atlas]

You have to do the same thing you see in the video with the box.

Whatever you hit with the raycast, you do a GetComponent on, get the UdonBehavior, and then you call any method like "TakeDamage"(defined by you) on that box.

[toxic glen]

I think ill just get Udon Sharp and make it in that. Finding the right stuff off the noodles is annoying

[dull stream]

What's a good way to group data? For example I want an array of rooms and references to a bunch of things for every room.
In C# you'd create a class or struct with all the relevant variables then stick an instance of that into an array.

What to do in U#?
Create a few arrays of the same length for each data type I need and have them all use the same index in each array?

Create a udonbehaviour just for storage? Would that impact performance at all, if there's no updates from it?

[wind atlas]

I use the second method for the convenience. It's just management logic so it doesn't really impact much.

[uncut kettle]

im curious is there a way to get avatars to have mechanics like other games such as onward with recoil and same with vests in the world?

[dull stream]

you're pretty limited in what you can do the player themselves

but you can simulate a bunch of stuff

people have made guns with recoil

for players tho you can teleport so move/rotate but you can't mess with the camera

Also, can we define our own layers for our worlds?

I want stuff to be invisible to players and only visible to certain cameras that I assign the layer to and the assign that as the reference camera. Is that possible?

[wind atlas]

I haven't done it myself, but I'm confident it's possible to create new layers if you need them.

Searching I found this:

#udon-general message

Although reference cameras don't keep your layer settings according to: #world-development message

[dull stream]

That sucks

Is there any way to make something not render for the player but do render for a custom camera then?

[wind atlas]

I have never messed with that. I just know MirrorReflection behaves a bit different with rendering, maybe that will work?

Hopefully someone else knows more.

[dull stream]

You can do fancy stuff with shaders but I was hoping it's more simple

[inland gyro]

I've been slamming my head into the wall all week with this one. Jump still isn't working.

I had it work before in all of my other worlds except for this one. I don't believe I have any scripts that's overriding the jumpImpulse.

[wind atlas]

Have you tried the following?
Make a new world scene for testing. Put in that script and experiment with the numbers. Just so we know whether it's working or not.

[inland gyro]

Okay, that is weird. Did as you said; jump works fine. Maybe I do have something in my main scene somewhere overriding the impulse. I'll have to do some digging.

That makes me well-knowing it isn't an SDK 're-import it' issue.

[dawn forge]

Hi, I wanna take the OnClick() function of TextMeshPro Button to call a method from my parent script. I guess it doesn't look at the custom methods we implement?(This is U# btw)

I want to avoid broadcasting over the net because there will be multiple instances of this game.

[inland gyro]

I might need to see the rest of the components too.

[wind atlas]

SendCustomEvent won't broadcast it, it will just call the method locally.

I'm assuming that's what you want to do.

And yeah, your custom methods are not exposed because they are not C#.

[dawn forge]

Ahh gotcha, thanks for the info 👍

[inland gyro]

Problem solved. I don't know what caused it, but the solution was creating a new Empty and just pasting the VRCWorldSetting script in there and doing it over.

[radiant lava]

Is everyone else Audio messed up a little bit

[floral dove]

this channel is for Udon discussion, you can chat about general topics in #vrchat-general-1 #vrchat-general-2 or a few other places

[visual elm]

i've been thinking of adding an event to display a name of a user that entered the world and/or leaves, but i have no such luck finding any available videos about it, can someone help me?

[floral dove]

this one is pretty close, playing a sound when a player joins: https://www.youtube.com/watch?v=r3Nu07EAlAQ

[visual elm]

ok, but still, do you know the name of the event where it displays the player's name?

[night viper]

There is no event for that, but you can get the name from an event that displays the VRCPlayerApi, like OnPlayerJoined by using "Get displayName" node

[visual elm]

oooo, this will surely help, i'll test it

[floral dove]

btw @visual elm - you can find all the methods and properties of VRCPlayers here if you're ever curious about what else you can do: https://docs.vrchat.com/docs/players

[visual elm]

alright, i'll look into it

[sweet star]

Hey, weird thing.

https://i.imgur.com/QNR5mcM.png

I can not type in that box.

Nor can I even find the node "Event/Custom Event" in order to receive events.

What's going on?

[floral dove]

instead of typing in a string by hand, hook up the instance of the UdonBehaviour to which you're sending the event, and the dropdown will fill in with the possible events you can send

[hallow iris]

and worst case just use a string XD

[sweet star]

The tutorial I'm following implies you can type in that box.

[floral dove]

yes - you can always just use a string const node, but if you can hook up the receiving UdonBehaviour then you'll have a better time if you ever change the name of the event in the future because it will show you that you have a mismatch

[sweet star]

And I can't even find the "Event/CustomEvent" node to recieve events, so I'm not sure how to add them to the list

[floral dove]

can you hook up the receiving UdonBehaviour to populate the list? This tutorial was made before we upgraded this functionality.

[sweet star]

I don't know what you mean by "the receiving UdonBehavior."

[floral dove]

events are sent to UdonBehaviours, so I mean the UdonBehaviour that will receive this event.

[sweet star]

OK, self then 😅

[floral dove]

ok, easy. so all you have to do is create the event and hook it up to something, then it will show up in the dropdown

[sweet star]

How do I create the event, then?

Again, I think I'm following an outdated tutorial, because I can't find the receive node.

[floral dove]

you can learn all the different ways to search for nodes here: https://docs.vrchat.com/docs/searching-for-nodes

[sweet star]

no I know how to search for nodes

Event/CustomEvent does not exist

[floral dove]

ok - so what happens when you search for "Custom Event"?

[sweet star]

Oh crap, it's two words isn't it.

[hallow iris]

yes

Event Custom

is the name

[sweet star]

(That's kinda all over the place.)

[hallow iris]

then its poping up

[sweet star]

Thank you! OK, so if I make an event in here, it'll show up in the dropdown.

[floral dove]

you need to make an event and hook up its flow to something. You can just hook it up to Debug.Log for an easy connection.

Udon doesn't compile events that aren't connected to anything, so that's the minimum to get it compiled into your program.

[sweet star]

Awesome, it's working, thanks so much!

[floral dove]

you're welcome!

[hallow iris]

welcome

[sweet star]

Udon is dope, honestly. Just want to say, as a Python guy not used to visual languages or some of the paradigms used here, it's pretty dang intuitive and powerful.

[hallow iris]

so momo dear sir cose it seems your the only one that has an actuel idea of udon XD, shouldnt this enable the collider that is connected on the game object <.<? atleast everthing to the usestation works but for idk what reason the collider is not getting aktivated

[floral dove]

If you're comfortable with text-based programming, you may find this community project useful: https://github.com/MerlinVR/UdonSharp

[hallow iris]

The Capsulecollider variable is just connected with it self

leaving it empty also didnt worked

[floral dove]

that should trigger the 'UwU' event on the UdonBehaviour referenced in the variable "PlayerCapsuleUdon", is that the same UdonBehaviour as the one running this program?

[hallow iris]

yes its all the same object

as sayed tryed it also without specifiyng everything

[sweet star]

Hey, can you make an object have colliders players can stand on and move around? Doesn't seem to work for me, tried like, parenting a non-pickupable object to it, etc.

[hallow iris]

this object right here has no collider and follows the assigned player the whole time

as soon as Hp are depletet the assigned player gets set onto a station that is in this capsule

the capsule needs a collider so it can be picked up by a hunter

but aktivating the Collider just.. doesnt happen <-<

[slim hound]

You would need to have another object as a sibling instead of a child that follows using a parent constraint or something

[sweet star]

in which direction?

the collider one has the constraint or the pickup one?

[slim hound]

Collider

[sweet star]

Still can't seem to walk up it.

[slim hound]

Make sure it's not on the pickup layer?

[sweet star]

ok now it's just prop flying.

[slim hound]

Make a custom layer that only collides with the PlayerLocal layer and change it to that

[pseudo parrot]

So like, I have this issue. when I migrate my project to 2019

I've already followed the steps on migrating a project from importing the lastest SDK
Making a new scene
Then migrating to 2019

[lucid arrow]

Just a noob here. But, how am i not able to see an open udon graph? Does this have to do with which type of version SDK or errror with unity version?

I'm using SDK V. date 2021.08.11.15.16
Unity 2019.4.31.f1

I would love to make some mirror toggles and actionable triggers for the world, but at the moment I have to leave mirrors on for users entering the world.

[raven crescent]

Hello

I have small question about VRC api

VRC_PlayerAudioOverride is it only works on sdk2? it seems on script

but not quite explain in api document

[pseudo parrot]

Anyone know how to fix this. Like the SDK3 does not show Build.

[cold raft]

look in your console, at the bottom left, press clear and look at the top errors

[pseudo parrot]

There's nothing much.

[cold raft]

indeed, well the first one is a hard error, that could be problem but its to vague that i had no idea what wrong with it

[pseudo parrot]

I already replaced the SDK3 and Udon#

[wind atlas]

Make sure you can create a new fresh scene with a scene descriptor. Does it still show nothing? Then you might need to reinstall the sdk and udon.

[pseudo parrot]

I did

[young oasis]

hello, im creating a world rn, and i could build and test , but now i keep gewtting this message

and i dont wanna start over

[verbal lance]

Is there a way to parent a object directly to the player's head? I am currently doing this but there is a considerable delay when the player turns their head and I need none.

private void FixedUpdate()
{
    var trackingData = playerLocal.GetTrackingData(VRCPlayerApi.TrackingDataType.Head);
    transform.SetPositionAndRotation(trackingData.position, trackingData.rotation);
}

[scarlet lake]

did you try reimporting the sdk?

[scarlet lake]

Might be because youre using FixedUpdate? I've had hud elements using LateUpdate and don't remember any delay except when moving very fast

[mighty fjord]

There's an event called PostLateUpdate specifically for this. PostLateUpdate runs at some point after the IK, so it won't have the latency.

[scarlet lake]

Also does anyone know if there's a simple way to push my serialized variables to the top of the wall of text if I distribute a component as an assembly code asset?

[verbal lance]

Thanks that improved it a bunch

[mighty fjord]

👍

[cinder glade]

so it seems to be that the OnPlayerParticleCollision event detects when a particle hits the player but only if the model of said player is within the VRC Capsule. Has anyone figured a way around this?

[uncut kettle]

ah thanks tbh im just trying to find out if i can add pocket systems depending on the vests u find and all

[dull stream]

You'll have to create it and teleport it to the player every frame

[summer scroll]

has there been any project with a music fading into another when reaching a trigger?

[uncut kettle]

it sucks im new to coding lmao

[verbal lance]

Actually after testing inside of VRChat it seems that PostLateUpdate never actually fires, it only works in unity with CyanEmu, any idea why?

[uncut kettle]

can i use C# or is udon different

[dull stream]

you can use U# which compiles C# to udon

but there's quirks, you can't just write C#. udon has it's own limiatations

[mighty fjord]

That does sound a bit strange, I've not got much experience with PostLateUpdate yet though, so I don't believe I'll be of much help. You could make sure that the script isn't crashing ingame atleast I guess.

[verbal lance]

hmm I don't see anything in the logs, I guess I'll add some prints

ah I assume i need to add override

ye it works now, although even with PostLateUpdate there is too much delay for my usecase

[floral dove]

the issue is probably variable update time between the continuously-synced object and the Player, which are handled differently. Instead of having the player who owns the object update its position each frame, you could have each client set the position of the object each frame based on where they see the player, which would keep them in sync.

[verbal lance]

Well I only need the updates to be client side, I am moving cameras based on the player's head tracking to create a volumetric display using render textures, it works perfectly now in VR however because VR head movements are so precise and you have a extra layer of depth every little bit of delay is noticeable in the display

the camera movements only have to be client side, no synchronization needed

[floral dove]

oh ok - I thought the issue was seeing it lag behind other users 😛

[uncut kettle]

i get it

[verbal lance]

Hmm are PostLateUpdate calls received through the network because that would explain the minor delay.
The reason I assume that is the case is because when I set Synchronization to none it stops being called

[floral dove]

they are not. There are currently some issues with SyncType none, I don't recommend using it until they're fixed in the next release

[verbal lance]

hmm actually that wouldn't have been the reason anyway, same small delay happens with regular LateUpdate

questioning my sanity lol

I am thinking the camera itself might be delayed but i can't see the delay in non vr mode and don't know how to test what causes it

oh this must be a shader thing or something, only the right eye is visibly delayed unless i am crazy lol

[dull stream]

Would setting it to manual and then just not doing it achieve the same thing?

[floral dove]

roughly, yes

[verbal lance]

this is a weird ass issue actually, the delay is present when looking through through my vive and closing my right eye but when i look at my monitor (still while in vr mode) the delay is not there, or atleast i can't see it

[peak thicket]

is there any way to make a video player where everything quest can also see that is a url typing one

[floral dove]

quest users can see videos with direct links - ie they end in something like ".mp4". They cannot see videos from providers like YouTube, etc.
https://docs.vrchat.com/docs/video-players#supported-video-hosts

[peak thicket]

i could fix that if i could change the mobile to video with a whole other texture

[tacit harness]

If i wanna say have a object move with the hip like a Walkman or something that you can change song or or something just as an example

How would i track the hip movement/position so the object moves with it

pls dm me or mention me in here if you can help i would greatly appreciate it

[cold raft]

the playerapi allows you access to bone positions such as a the hip bone

[ashen vine]

They will gona do a fullbody tracking with the oculus?

[cold raft]

Huh? With ocolus you need an extra way of tracking your feet and hip in order to get full body, like SlimeVR

[visual elm]

i'm still stumped by the fact i want to add the player joined/left message in my world, i want it like "'User' has joined." "'User' has left." I'd like a formula in Udon graph to see how it looks like, if there are any... my head hurts thinking about it and i'm still a novice in Udon Graph

[floral dove]

to do this, you can use String.Format, which will replace things in brackets. So you can write {0} has joined as the string, and the plug the PlayerApi.get displayname into the object slot on the String.Format node

pretty sure we have some examples of this in the UdonExampleScene

[visual elm]

hmmmm

i'll look into it

[cinder glade]

Does anyone know the Height and Width of the player view so that I can afix a Hud to the player

[wind atlas]

You have to calculate it yourself since people can have vastly different avatars.

[cinder glade]

how does one calculate that

[wind atlas]

There should be GetTrackingData which holds position and rotation of whatever you specify.

In your case you need to get the Head.

[cinder glade]

Sorry I should specify. I meant the view camera Height and width

[floral dove]

You can check out this example project which attaches an optional HUD to a player. It doesn't size up/down but seemed to work well for most players in our tests: https://docs.vrchat.com/docs/obstacle-course

[wind atlas]

Oh, it sounds like you mean to resize canvas properly?

[cinder glade]

yeah

[wind atlas]

Look at the obstacle course that was linked, it probably has good examples for that.

I should probably check it out myself first. I did my own, but I had to eyeball it pretty heavily in VR because you have to use world canvas for that. @cinder glade

[vast sparrow]

very basic question
how do i get a pickup object to respawn if it falls into the void

[scarlet lake]

it should respawn automatically when it hits the respawn height set in your vrcworld scene descriptor

[vast sparrow]

alright thanks

[sweet star]

Quick question: trying to make a button that destroys any card GameObjects that are within the bounds of a box, how do I go about this?

[fading cipher]

Give the box a script that collects a list of items that are in it, then when you press the button have it loop through the box's list and destroy each one @sweet star

[sweet star]

What node would I use for getting what object are inside of it, and can I make sure that's not a player 😄

[fading cipher]

You can't destroy the player, if you try to access a player in any way like that the script instantly crashes 😛

Not sure about nodes, I don't use Udon Graph 👀

But you'd give the box a collider and mark the collider as a trigger, that way anything that enters the box you can check what it is and add it to your list if it's what you expect

[sweet star]

Can I get the collider from the object so I can use the object as the public variable?

[wind atlas]

Do you know about OnTriggerEnter? It gives you the collider that has entered as an output.

[sweet star]

See but then I have to put the script on all 200 cards instead o fjust on the box itself.

What I want is a button that deletes all the cards inside a box.

[wind atlas]

What you would do is, have one script that has a big collider zone that's a trigger. The cards only need one collider on each of them. No scripts on the individual cards required.

[sweet star]

Will "OnTriggerEnter" placed on the box fire when a card enters it? The collider on the cards can't be a trigger because they need to be pickupabale

[sweet star]

I'm trying to get this UNO thing done tonight and I'm just not sure what the best way to handle this is.

Network and event stuff is new to me.

Can I get a list of all objects that are inside a GameObject from a GameObject variable?

That's really all I need

Then I'd have Button Interact > [ GameObject deathzone > GetAllInside > For Loop {Destroy} ]

But I don't know how to GetAllInside

[wind atlas]

Don't your cards already have a collider on them? Pretty sure pickups need it.

[sweet star]

Yes a collider, not a trigger

[wind atlas]

So all you have to do is make a Script with a Collider set to "IsTrigger" on a random game object.

Then in that script, you call the event OnTriggerEnter.

Any card that enters this collider will trigger that event.

[sweet star]

But I don't want it to happen OnTriggerEnter, I want it to happen on button push

[wind atlas]

Yes, we are only collecting the cards here. So in OnTriggerEnter you would add that card to a list.

The button would then call a something like "RemoveAllCards" on that script.

We can just go through that list and remove every card.

[sweet star]

So I can put OnTriggerEnter on the box, not each card, and that works?

[wind atlas]

What box?

Oh, box collider?

[calm smelt]

I think I can explain what he wants to do better

[wind atlas]

Sure go ahead.

[calm smelt]

He wants to have it where if he has a ton of objects in a certain area, he can hit a button to only delete the objects on that area

[wind atlas]

Yeah, but how do you want to know what's inside that area without collecting the cards first?

[sweet star]

I'm just not sure how to collect the cards 😄

I'm trying here.

So, does the script need to be on the box?

[wind atlas]

Do you mean box collider?

The area we want to remove the cards at?

[sweet star]

OK one sec.

https://i.imgur.com/QiGyB4j.png

The red box has a collider on it that's set to trigger.

[calm smelt]

The players put the cards In themselves

[wind atlas]

Is the red box where you want the cards to disappear from once you hit the button?

[sweet star]

yes.

[wind atlas]

Then yes, that's where you attach the script.

[sweet star]

OK, roger.

@wind atlas So I imagine something like this, just not sure how to append to the list

https://i.imgur.com/Jhs1VzW.png

[wind atlas]

Give me a minute.

Yeah, I don't know how people do lists in udon, that seems annoying. I use udonsharp for that.

Maybe parenting solves it better, that would be my "lazy" approach:

[sweet star]

oooh that's kinda gross

uh hmmm

[wind atlas]

You might need to identify your cards better, I only check if it's a pickup right now, this will destroy ALL pickups.

[sweet star]

so, like, I have all the cards in a parent group?

would that help?

[wind atlas]

Yeah, hierarchy is basically a list, I can just show to delete one sec.

[sweet star]

https://i.imgur.com/R642sgr.png

[wind atlas]

And on exit needs to be done too:

Honestly, I just realized lists aren't that complicated, I can do it too if you want.

[sweet star]

Yeah ,can we try that method?

It's kinda what I'm set up for rn.

[wind atlas]

I just realized it's easy if we define the array from the start.

[sweet star]

Thanks a ton for the help on this, BTW!

Again, I'm a Python guy, so types and graphs and such are out of my field 😄

[wind atlas]

I'm same honestly, I use U# to code it.

It helps knowing the Unity API to read those graphs.

For example, I'm not sure if this will work:

Why is that last parameter not named?

[sweet star]

lol what?

that's, uh, odd.

[sweet star]

I'm somewhat confused what this code does.

[wind atlas]

I try to initialize an array. But I found you can just chose the array size in the editor too.

In python they are dynamic, but here they need a fixed size. Makes things annoying...

Especially in graph.

I'm going to chose a lazy approach again, we will rotate the index to add stuff.

[dull stream]

That's how arrays work

Lists get auto resized but aren't supported by udon yet, but soon

[hoary echo]

Not sure if I should put this here or in the Quest dev channel, but I've got a hell of an issue that googling gives me no help with. I've got a Unity 2019.4.31f1 project that refuses to switch build targets. When attempting to switch from Windows to Android, it locks up on a .compute file, ram goes to 100%, and it crashes.

When I manually remove all of the .compute files, the bastard locks up anyways and does the same thing. This a known issue?

[wind atlas]

@sweet star Okay, I'm realizing if you use an array, you have to do stuff like check if the item is already in it and stuff. This is getting way too complex for a graph. Have you tried U# yet?

[sweet star]

No, I don't C# 😭

Can I not just...

https://i.imgur.com/hrPYk9e.png

[wind atlas]

I wish

That's why I used the hierarchy earlier.

Honestly, the only thing you need to change is OnTriggerExit. Instead of doing parent = null you just put it back to your old parent.

[sweet star]

Is there not just a "get all objects in bounds X-X2, Y-Y2, Z-Z2"?

[wind atlas]

Good question

[sweet star]

I can't change the parent or it won't be in my object pool 😭

[mighty fjord]

How about Physics.OverlapBox?

[wind atlas]

https://docs.unity3d.com/ScriptReference/Physics.OverlapBox.html

Yeah, seems like it might work.

[sweet star]

Can I just plug in a Collider and assume the stuff instead of defining center, halfExtents, etc?

And if it returns a Coliider[], can I derive GameObjects from that?

[mighty fjord]

You could use a regular collider as a reference, yes. You might have to do some extra translations, but luckily there are some methods which help with this.

[sweet star]

Sorry, I'm still in my early learning stages of Udon, so I'm not sure how stuff like that works yet

(I accidentally made a semi-popular world and now feel obligated to make it like, good) 😅

[sweet star]

This is what I'm working with if you didn't see it.

(That's in a test world.)

Goal is you click a button, all the cards in the red zone get destroyed (and hence are back in the object pool)

[wind atlas]

For the OverlapBox method you can try this: https://answers.unity.com/questions/1729111/how-can-i-get-an-overlapbox-with-the-exact-same-si.html

Also, yes, you can get the game object the collider is attach to. Just drag it out in the graph and you should be able to type in "get gameobject"

You might also want to rethink why you need to destroy if you have a card pool. The idea behind a pool is that you don't destroy but reuse them.

For example, if all you want is something like a trashcan for cards, then you could have one OnTriggerEnter and just remove that card there already, no need to collect them all first.

[sweet star]

I'd like it to happen on a button press.

So I can't have it happen automatically.

[wind atlas]

Another idea, you could assign a state like a bool to each card. And just iterate over them.

[sweet star]

It's for UNO, so you want to "reshuffle" all the cards on the table, but not the ones in hands.

[wind atlas]

Wait, are the cards static? Like, there is a set amount of cards in the world?

[sweet star]

Yeah, it's an object pool.

[wind atlas]

Are you using the VRC Object Pool?

[sweet star]

Yes I am.

[wind atlas]

Are you aware of TryToSpawn and Return? I'm asking because you used Destroy earlier.

[sweet star]

Oh, uh, yeah, I am. Oops 😄

Still learning 😛

[wind atlas]

Yeah no problem. You have to learn a lot of C# concepts, Unity API and VRC on top of that.

Anyway, I found a good compromise:

[sweet star]

OK, so this is setting a value on the card when it enters the trigger?

[wind atlas]

No, as you can see I create a boolean array. You set it to the number of cards you have and then just toggle the bit on or off.

[sweet star]

oh so if you have 8 cards it's like [False, False, True, True, False, False, False, False] and then I suppose you'd make the button get all the cards that are True and Return them?

[wind atlas]

Yeah

[sweet star]

Do I have to duplicate the code and invert it for Exit?

[wind atlas]

OnTriggerExit is the same but obviously just false:

Yes

[sweet star]

And then how do I remove all the True cards?

Also, why do I have to GetComponent?

[wind atlas]

Because literally anything could enter that collider and we have to detect it somehow.

I just chose to see if it's a VRC Pickup.

[sweet star]

Ah, I see, that makes sense.

No way to test if it's from the specific ObjectPool, is there?

[wind atlas]

You need to loop over the pool yourself to make 100% sure it's in there.

You could do that yourself instead of the get component.

[sweet star]

Sounds like a lag machine, though 😄

[wind atlas]

True, I'm not an uber expert either, maybe there is a better way like using Tags or Layers.

Something like that should work. I also forgot to reset the whole array to False afterwards.

I hope that makes the idea clear though.

Best idea is to make it work first, then optimize.

[sweet star]

OK, thank you so much, I'll test this out.

[scarlet lake]

nothing like wasting a day troubleshooting cause I forgot to set a variable to public 🤦‍♂️

[sweet star]

https://i.imgur.com/zQ41xRf.png

[sweet star]

So, uh

https://i.imgur.com/G7egnZS.png

I can't seem to get the event

Even though I set it up above

[scarlet lake]

are you not setting the event name

[sweet star]

I am in the code above

The big graph is "deathcube"

[scarlet lake]

in the bottom one it looks like event name is empty

[sweet star]

yes, because there's nothing in the dropdown

that's why I'm confused

[scarlet lake]

i'm not really great with udon graph, I know in udonsharp it has to reference a public method in the other behaviour

[sweet star]

I'm kinda unsure what you mean by that.

[scarlet lake]

i think the target value of the event send has to also point to a reference but I could be wrong

oh wait nvm

[sweet star]

?

[scarlet lake]

I'm just not super clear on how the graph stuff translates cause I dont use it much. try clicking your deathzone variable up there and see if it lets you choose public/private?

[sweet star]

It's set to public, and set to the GameObject with the above large graph on it.

[scarlet lake]

in that case I'm not sure why it's not available

[sweet star]

this didn't help

https://i.imgur.com/3pTi3A6.png

[night viper]

You could create a Constant String and attach it to the EventName if the event name will always be the same on the target udon behaviour

[sweet star]

sure, why not 😅

ok I need to construct a debug string with replacements, is that even doable

I found LogFormat but I'm not sure what it wants from "context"

ok wait there's a version without that

ok so how to a construct a list

cause I don't see how to plug an arbitrary amount of items into a node

I'm so at a loss right now, I've been at this for hours 😖

[floral dove]

are you ever constructing the badCards array, like perhaps at Start?

[sweet star]

No I am not, sorry, was unaware that was required.

[floral dove]

yes, arrays must be created before you can use them

[sweet star]

how do I go about that 😄

[floral dove]

you can use the bool[] constructor node to create it

[sweet star]

(python, I tell ya, it messes with you're head.)

[floral dove]

oh yeah - python doesn't even require you to declare variables

[sweet star]

like I don't even know where to start with this lol
https://i.imgur.com/mV22uao.png

[sweet star]

listen, it's nice.

[sweet star]

there isn't even like a way to plug these in 😄

[floral dove]

that's because you haven't made a "Set Variable" node for badCards yet.

[sweet star]

so I have this

https://i.imgur.com/3vplJOJ.png

but still not sure where the constructor goes or what the number there is

I feel like I look like an idiot here 😅

[floral dove]

in C#, you construct an array with a particular size: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/arrays/

so you put that size as an int in the constructor

then connect the array that is made from that to the instance input on a Set badCards node, which you still need to make.

[sweet star]

Are you talking about a different node then the Set node that's there? Because I'm not sure which you mean.

[floral dove]

yes - if you want to set the value of a variable, you need to create a Set Variable node: https://docs.vrchat.com/docs/special-nodes#set-variable

[sweet star]

https://i.imgur.com/A3E7CUd.png

I feel so close!

https://i.imgur.com/3YdLU5L.png

[floral dove]

https://docs.vrchat.com/docs/udon-node-graph#drag-and-drop-for-variables

please read through the basic docs and examples! Lots of the issues you're running into are covered 😄

[sweet star]

OK, to be fair, that's not made clear in-editor.
Thank you so much.

I accidentally made a semi-popular world so I'm tripping all over myself trying to improve it.

I really appreciate your guys' explanations and patience.

[floral dove]

if you ever forget, this is what shows up when you drag a variable from the window:

(capture doesn't show my mouse but it follows you around)

[sweet star]

And after all that, that wasn't the bug 😄

[sweet star]

I don't know how I missed that, really 😬

I don't know if this is helpful, but here's my Graph Code.

I'm just at my wit's end with this, I've been at this since, like, 2PM and it's 10PM LOL

[floral dove]

I'm sorry that wasn't the fix for it. I'm off for the night, but I'd recommend you add some debugging as a next step: https://docs.vrchat.com/docs/debugging-udon-projects

[sweet star]

Will do, I appreciate everything. I'll poke at this and maybe look at it with fresh eyes tomorrow.

[severe tree]

Can someone potentially explain to me why the Parameter Change event is not sent in this arrangement:

but is sent the moment the second set node is taken out of the equation like so?

Just wondering in the case of this being a bug, but if it's intended behavior or I'm just overlooking something obvious here then I don't want to bother writing up a simpler example for the report.

Nevermind, I've narrowed it down to the fact that the division of the float is attached to both sides of the branch and tested it to make sure. This is an issue in other regards with the execution pins but I didn't think that the same problem existed with regular parameter inputs as well?

[haughty hearth]

I have an UdonBehaviour on a GameObject that I only want to run locally. So I set it's syncronization to "None" in the Inspector, but now the script doesn't run at all. Am I missing something?

[desert grove]

Is there a reason VRCUrlInputField isnt exposed to text(set/get)? And does anyone have a brute work around?

[hallow sable]

is there a way in udon to see if a player is moving?

like if a player is moving do something? in udon sharp

[valid oar]

Anyone have experience with JetDogs voice amplification prefab? It works in amplifying the voice of players that enter the volume but then it stays there with no apparent means of switching it back, even by entering another voice zone with Voice Gain and Voice Far set to 0.

@haughty hearth I don't know how your program is set up nor have I tried turning off synchronization but you're sure it's global if synchronization is on? Most programs should be local by default unless you use networking nodes.

[hushed gazelle]

Getting an odd error when testing a vehicle, It's only syncing for other players while the vehicle's moving, and when I check the log it's full of the error;

Error - [Behaviour] Caught ArgumentNullException: Value cannot be null. Parameter name: Received a null value when encoding a Single

[hushed gazelle]

Fixed it; I was passing a value incorrectly between scripts.

[tropic canyon]

synchronization mode none is bugged at the moment, don't use it for now

[tropic canyon]

use the Input events: InputMoveHorizontal and InputMoveVertical to get the player pressed inputs, they should be moving if it's anything besides 0

[hushed gazelle]

So, I think I've found an Udon bug; If you tell a script to set a synced value in another script, it'll go to all instances of that script and not just the controller you publicly assigned.

[mighty fjord]

Go to all instances of that script?

[hushed gazelle]

Like if you have several duplicated sets of Object A sending instructions to Object B. If you have Object A set a synced value in its assigned Object B, it'll go to ALL the existing copies of Object B that you own.

[hallow iris]

Ohhhhhhhh there is the on variable change i serched

[tough finch]

Is there a way to make videoplayers more stable? Since a month literally every videoplayer I tried has this issue where sometimes a youtube video plays fine but sometimes it seems to be buffering(?) throughout the whole video to constantly resync.
I looked into proTV, usharpvideo, wolfe, videotxl but they all have this exact same issue on multiple different clients/setups.

[dapper lion]

avpro be like that

[tough finch]

I'm already using the unity base because avpro was even less stable

[fiery yoke]

There is multiple points of failure, that are completely out of the control of creators. The biggest problem is YTDL. Its a tool of sorts which is used to download a video file from stream provider like youtube. As this is not supported by youtube, it needs to regularly be updated to keep up with changes from yotubes side.
Another problem is the Video Players themselves namely the internal Unity player and the AVPro player. AVPro specifically is intended to be configured to be used with specific formats and codexs, while VRChat just uses it as a catch all.

[dapper lion]

protv allows you to switch to unity videoplayer easily

[fiery yoke]

However also the UnityPlayer has certain issues that are internal.

[tough finch]

do you know if there's any ETA on when they will fix this? because I'm actually losing world users over this and its just pointless to invest time in features for a dance world if the videoplayer cant work >.<

[fiery yoke]

And ofcourse your computer might also have incompatible drivers and auxiliary software which might need to be updated, reconfigured or replaced.

[tough finch]

yea its not specific to my pc, the entire community that I host is having issues

[fiery yoke]

That being said, its also very likely that the video player made by a creator is not programmed well and causes these issues.

I was working on a Video Plqyer myself, but a major bug from VRChats side prevented me to continue + I got busy with work

[dapper lion]

if its a dance world. you should def try using unity videoplayer for stability in that sence as avpro will need to be updated to a version where those issues are no longer present

[tough finch]

im already using the unity base 😊

[dapper lion]

oh right. then youre doing what you can do basically

[tough finch]

I see I see, but if more than 5 videoplayers have this issue then it must mainly be a VRC issue

[dapper lion]

theres no true way to fix it. especially if its constantly changing urls to load in

[tough finch]

yea thats the problem, new url every 3 - 5 minutes

[fiery yoke]

If it's the exact same issue then yes...I think I also had some weird buffering issues with my player

[tough finch]

we have a database of 5.5k videos so self-hosting is also not an option + not legal

[dapper lion]

i would say what youre describing is the avpro buffer bug. however i would like to point out that at some point, vrc updated how they synced videoplayers and from point of view. it was scary how they did it. so it could be a by product of that even though protv has that autosync function disabled in favor for its own

so if all videoplayers have the same issue and all have avpro. its most likely avpro

[tough finch]

I use the unity videoplayer base 😊

[dapper lion]

right. so you should be fine

[tough finch]

and I disabled their resync function when they launched it

because it would crash entire lobbies to desktop

any specific fix for this error? or is that also internal?

[fiery yoke]

Probably means the video is age restricted or unavailable in your country

[tough finch]

thing is, if I load a different video and then go back to that one it does work

its not age restricted and not unavailable, its one of the videos people dance to often in my world

[fiery yoke]

Hmm that's odd. Dunno then

[tough finch]

extremely frustrating

I don't see why there is not a proper videoplayer within VRC since its so central to world creation just like mirrors

I just want to create cool content, not debug a videoplayer that breaks with each update >.< (/endrant)

[viscid reef]

if you're having issues with youtube videos being really slow, its probably this issue https://github.com/ytdl-org/youtube-dl/issues/29326
tl;dr youtube has been rolling out changes that throttle video loading speeds if it detects videos are being downloaded via 3rd party means such as youtube-dl

[tough finch]

ahhhhh I see, that makes sense, ty for sharing

[hushed gazelle]

I forked my own player off of AVPro, and it's turned out alright for doing both Youtube and Twitch streams in the one player despite absolutely having the stutter issue. (The trick is to not let it pull the video's length if the word "twitch" is in the URL because it'll get real angry at getting Null back).

[visual elm]

i'm trying to figure out how to make the floor slippery like ice, I watched some videos about it as to apply physic material on the floor, I trying put both frictions to 0.1 and applied to the floor, but when i tested it, it does nothing, so.... is this possible? i've seen a different world that you can slip around the floor like ice on a flate surface

i want it to be players slipping around on a slippery floor

[wind atlas]

@visual elm That's an interesting idea. I haven't used physics materials yet, but I'm guessing that you are not attaching it to a player.

But, we don't even have direct access to the player.

Which means it shouldn't be possible to use Physics Materials unless there is some unofficial way to get to VRC's player controller and attach stuff to its collider.

[wind atlas]

To make it slippery, you could simulate it yourself using TeleportTo in an update loop, that's the only thing that I can come up with at the moment.

[visual elm]

i want to slip and slide around like on ice, but hmmmmm, i'll see what can be done, but... do you have the udon graph formula for it?

[hushed gazelle]

I'd say the better way to do it would be to put them on an invisible seat and respond to player movement by applying force to the chair.

[wind atlas]

Chairs can also work. Try making a chair with the physics material so you can put them on the ice and they slide around.

You can learn about the force seating players and stuff afterwards.

[visual elm]

this looks promising

[slim hound]

It mostly works but may have issues maintaining velocity during frame stutters

[visual elm]

this udon graph is appled on an object, like a floor, correct?

@slim hound

[slim hound]

It could just be an empty game object anywhere

[visual elm]

ok, i will try that

i wanted to be on a slippery floor surface, like this:

[slim hound]

You would need to enable that udon behavior when the player enters that area

[visual elm]

like a collider with a trigger?

[slim hound]

Yeah

[visual elm]

ok

like this?

[slim hound]

You would want it as a trigger and use PlayerTriggerEnter/Exit events

[visual elm]

ok

so how do i set them up for playertrigger enter and player triggerexit?

[slim hound]

Like this and then have it setactive on the other udon behavior

[visual elm]

where will branch be connected to?

[slim hound]

A setactive node

[visual elm]

gameobject, yes?

[slim hound]

Yes

[visual elm]

ok, got it, so what do i connect the setactive node to?

[slim hound]

You shouldn't need to connect it to anything

[visual elm]

but wait, just like that?

where does storedvelocity come from, creating new variable?

[blazing hedge]

How do you destroy game object using button in world SDK-3 ?

[visual elm]

is this how it suppose to look like?

@slim hound

[slim hound]

The Enter/Exit trigger would need to be a separate udon behavior

[visual elm]

separate, got it

but is the setup correct?

[slim hound]

Looks like it is

[visual elm]

tested it, at spawn, i feel slippery, which should not trigger

it's suppose to trigger on the terrain i stand on

am i suppose to match the x y z on the floor object?

[slim hound]

It should be disabled until you enter that area

On which trigger enter > set active

[floral dove]

I recommend you use Object Pooling instead of creating and destroying objects: https://docs.vrchat.com/docs/udon-example-scene#objectpool

[visual elm]

ok, so like Playertriggerenter > SetActve while Playertriggerenter > get islocal to set active to the value?

[slim hound]

When the player enters the area you enable and on player exit disable. get is local is just to make it so that it doesn't trigger from other players

[visual elm]

ok, but there's still something wrong...

when i spawned into my world, i'm slipping around, which is not suppose to do that

i have to make my way to the room where there are ice around to make that trigger to happen

[slim hound]

That game object with the udon behavior needs to be disabled by default

and enabled/disabled by another trigger collider/udon behavior

[visual elm]

that make much more sense, ok

ok, this is what i got, tell me what needs to be fixed:

[visual elm]

nice setup, i'll use that

[cold raft]

Udon is a form of art

[visual elm]

ok, here comes the final setups in 3 screenshots:

[slim hound]

You could test to see if it behaves as you expect first

[visual elm]

ok

no dice

[slim hound]

You should only have two udon behaviors

[visual elm]

on which ones?

Friction Trigger only has 1, and the empty object has 2 udon behaviors

and what do i put on storedvelocity?

[slim hound]

Probably faster to just give you a prefab for it

[visual elm]

ok, where do i drag the friction effect?

[slim hound]

Make it so that box collider is around the area where you want the effect to be

[visual elm]

ok, time to test it

still nothing, but wait...

am i not suppose to attach the Friction Effect on a mesh object?

[slim hound]

no

Can you show how you have it setup in the scene?

[visual elm]

sure

[slim hound]

That setup should work

[visual elm]

but yet it's not triggering... don't know why

do i need to add a physic material on the ice floor, or no?

[slim hound]

Shouldn't need one

Does nothing change at all when you enter that area?

[visual elm]

nope, nothing changed, no slippery effect whatsoever

[slim hound]

My only thought would be for you to open the udon graphs and press compile

[visual elm]

it works now!

but strange, it stops slipping around within the area time to time

[slim hound]

Yes as I said earlier likely to loose velocity during frame stutters

[visual elm]

alrighty, awesome, thank you so much

would you like me to credit you on my map? you've helped me so much

[slim hound]

Your choice, I don't mind either way

[blazing hedge]

How do you destroy game object using button in world SDK-3 ?

[rose surge]

Hello world; stupid question, can you use mesh colliders instead of box colliders for 3.0 pickup objects?

[blazing hedge]

I think all u need to pickup an object is a collider... so YES YOU CAN!

[rose surge]

I'll test it & see if it works!

[blazing hedge]

plz send help Anyone?

[floral dove]

I recommend you use Object Pooling instead of creating and destroying objects: https://docs.vrchat.com/docs/udon-example-scene#objectpool

[visual elm]

@slim hound by the way, the movement slows down within the ice area, i can't make the character jump, or almost barely move

[rose surge]

@blazing hedge It doesn’t seem like you can substitute box-colliders with mesh-colliders when creating SDK3 based pick-up items. I guess I’ll just have to make due with box colliders.

[slim hound]

It is reliant on framerate so if the framerate is too low it wont work

[visual elm]

i see

[visual elm]

Is there a way to disable jumps?

[floral dove]

sure thing: https://youtu.be/8yaQY0arCnc?list=PLe9XHNvXcouQjg5GULWGLj1tMzeythnQi&t=50

I recommend you read the docs (at the very least the ones pinned to the top of this channel) and check out the videos in our "Learning Udon" series: https://www.youtube.com/playlist?list=PLe9XHNvXcouQjg5GULWGLj1tMzeythnQi

[visual elm]

alrighty

[sweet star]

Hey, kinda an important question, any reason only the master can seem to spawn cards from an ObjectPool?

Just pushed a world update that I'm now realizing has that issue.

[floral dove]

not the master, but the Owner - that's how it works: https://docs.vrchat.com/docs/network-components#vrc-object-pool

If you want someone else to spawn a card, you can have them:

• Send a CustomNetworkEvent to the Owner, requesting that they TryToSpawn
• Take ownership of the ObjectPool and then TryToSpawn
• Set a synced variable like wantsToSpawn that the Owner watches for changes, and calls TryToSpawn when it does

[sweet star]

Thank you!

[scarlet lake]

Is udon named after noodle

Or coincidence

[sweet star]

@floral dove Do you mean Instance Owner or is Owner something specifically different?

[floral dove]

the Owner of the ObjectPool.

[sweet star]

Who owns the Object Pool?

[floral dove]

start here to learn how Networking works in VRChat: https://docs.vrchat.com/docs/udon-networking

[sweet star]

No, I'm aware of that, sorry, I mean how do I get if the current player is the owner of the object as opposed to the Instance Owner?

[floral dove]

If you read through the docs and the basic networked examples, you will have your answer, I promise 🙂

(and many more answers to other questions you will have!)

[sweet star]

I'm sorry, just panicking since I have a broken world up right now 😅

[floral dove]

gotta test before you publish!

[sweet star]

I honestly forgot you could test two clients locally 😬

Hey, learning a lot, right?

[hushed gazelle]

How can I get the inverse of just a single rotational angle? I want to set something to a postion and have it face the opposite horizontal rotation of that point.

[flat tendon]

Hello i am looking for verneons udon vehicles for oculas quest 2

[tacit harness]

How would i make a canvas menu where i have a slider on the left or right and i can scroll down the menu ?(If there is a prefab i would also take that) pls dm or ping

Thanks already

[wind atlas]

@hushed gazelle You could use Quaternion.AngleAxis. If by horizontal you mean like turning your head, then this should work:

transform.rotation = transform.rotation * Quaternion.AngleAxis(180f, transform.up);

[hushed gazelle]

That did it, thanks Puppet!

I just needed it as a teleport target, but the way it had to face was opposite the parent object.

[wind atlas]

If you have the parent, can't you just set the rotation to 180 directly? Since it inherits the rotation.

[hushed gazelle]

Nah, mobile object. Gotta be relative to it at the current time.

It's also not actually parented TO it, just talks to it.

[wind atlas]

@hushed gazelle I'm glad if that works already. I'm just wonder if doing it with eulerAngles makes it even easier. Going to try something.

[brazen pier]

I've got this set up to play an animation; how would I also activate the audiosource (on the left) when clicking this button?

[hushed gazelle]

You need an AudioSource and just tell it to Play

[brazen pier]

Here is the AudioSource, how could I let it play?

[hushed gazelle]

How do you make anything do something in Udon?

[brazen pier]

using nodes, but I was kinda asking which one to use 😅

[hushed gazelle]

It's literally "Play", lol.

[wind atlas]

I found a nice method btw:

transform.rotation = Quaternion.LookRotation(-ParentTransform.forward);

@brazen pier You need an AudioSource not GameObject for the variable.

[tacit harness]

https://i.imgur.com/ne2ELvS.png

how would i make it so that only stuff thats actually in the canvas is shown and for example when the right button is half outside only half of it is shown ?

[wind atlas]

@tacit harness https://www.youtube.com/watch?v=oDBVRcHhc0M

seems promising

and only 60s!

[tacit harness]

I dont seem to be able to get that working

QwQ

[hushed gazelle]

One of the VRC Prefab starter packs has a whole scene demo'ing how to do basic udon stuff iirc, including UI elements like text sliders.

[tacit harness]

Ahh okay got it working without still thanks so much for the help

^^

[brazen pier]

Thanks, got it working! :)

[visual elm]

can Quest players see youtube video if i were to set one up for PC/Quest players?

[floral dove]

check the docs: https://docs.vrchat.com/docs/video-players#supported-video-hosts

[vast sparrow]

im having a small problem that pickup's in my world wont respawn.
ive checked the respawn height of the world and changer it just in case but it just wont respawn
players do respawn but i needs the pickups to

is there an extra setting i need to turn on or script to attach?

[dawn forge]

Kind of being hurried last minute for this, but I am getting NULL when trying to obtain the component of a child gameObject.

Where buttonName = "Reset" AND this refers to the object running the script "Cards UI".

[wind atlas]

It looks like it's finding the "Text" gameobject in the scene since it's not crashing at that line and you are getting null in the debug log.

So are you sure there is a TextMeshProUGUI attached to "Text"?

[dawn forge]

Yes, I have to believe I am using the correct component, here is the inspector.

Re-added the component and it's now happy, but when I try to modify the "text" property it'll throw the object ref error, but I am getting the object name in debug instead of null. When I just read the "text" property, it'll return the value just fine.

[wind atlas]

What is your script attached to? Only that one button?

[dawn forge]

The Cards UI object which is the parent of the button and its child, Text.

[wind atlas]

And both have the TMP Text component attached?

[dawn forge]

Correct

[wind atlas]

That's odd.

Just to be confident, you could try printing the whole path you are at and which one are you accessing, there might be a mismatch.

[west mural]

actually, which one returns null, the gameobject or the component ?

[dawn forge]

The component's "text" object. I can read it, but when I try to set it, I get the object ref error.

[west mural]

i think textmeshpro might have a SetText function

[dawn forge]

Unfortunately the method is not exposed to Udon 😦

[wind atlas]

It works without it.

Maybe giving us the log would help. You say you have two objects with that script and the behavior seems a bit random.

Might also just do something like this:

Debug.Log("Me: " + transform.name + ", "Button: " + buttonName + ", Is Found: " + buttonGUI == null);

[dawn forge]

I reloaded TextMeshPro package and its essentials and it seems to behave just fine now

It's weird because I have the same concept on another object and it works just fine, this object that had the issue was added in my new revision after upgrading to the latest VRChat's supported Unity.

[hallow sable]

isn't there a way in udon to change the animator for a player? curious how to do that

[zenith echo]

Hello folks! I'm trying to set up an OnEnterTrigger event, but one thing I'm really missing from SDK2 is the ability to have this only react to objects on a certain layer - I can't figure out how to do this properly in Udon, any ideas?

I've tried using Get LayerMask, but I think there's a bug here, whenever I change the layer away from "Nothing" it fails to save the value I set it to, so when I reload it goes back to Nothing, any idea what's happening there too?

[dark blade]

what is the function to be able to click on an object and it send you to a connected link

[grand temple]

that's not exposed to the public

[slim hound]

That's an issue with graph. you would need to create a public LayerMask variable and set its values in the inspector

[dark blade]

huh. some people who arent developers have access to it. how do they have it

[tepid salmon]

is ther a problem to have 3 udon behaviours on the same object`?

[dark blade]

probably not

[tepid salmon]

ther ar all local should be ok i think

[zenith echo]

Yeah, a buddy of mine helped me come up with a workaround - from "Collider other" we did collider.getGameObject, then connected that to GameObject.GetLayer, then used an int.Equals node with the GameObject.GetLayer int value plugged into obj, then the layer number we were looking for entered into instance - one Branch node later and it worked as we needed it to!

[slim hound]

Yeah that works too

[zenith echo]

screenshot for reference

[plush stump]

One of my timer in udon program stop working when a player left the room after the game began, is there a fast way to test and located where the problem is?

[grand temple]

are you checking that the player is valid before trying to do anything with them or get anything from them?

[hushed gazelle]

Depending on what you're doing in your game, maybe it's still trying to address the exited player in whatever player-management coding you have, but because they're not in it anymore it's not liking the now-null value.

[plush stump]

yeah I think it should be a null player causing the problem, just wonder if there is quicker way to find it out, right now I have to edit some codes, start 2 clients to test out and repeat.

will player left also trigger OnplayerTriggerExit Event?

[grand temple]

uhh I don't think so

[plush stump]

thanks

I think I'm doing a IsValid check everytime I call VRCPlayerApi except GetLocalPlayer, since Udon program is local by nature, I don't need to check IsValid when using GetLocalPlayer, right?

[grand temple]

local player should always be valid, yes

are you using Utilities.IsValid or playerapi.isvalid?

[plush stump]

is there a way to highlight all IsValid node or specific variable in the graph?

Take a lot effort to check all of them everytime

should I use playerapi.isvalid?

[scarlet lake]

my sdk have error

[wanton palm]

can you import classes into other classes with udon?

like fe I have a class responsible for making some calculations. Can I import that into another class to make use of some of its methods?

[cold raft]

not sure what you mean with classes, if you mean udonSharp then yes

[wanton palm]

something like this

gives me error

System.Exception: Method is not exposed to Udon: Void .ctor(), Udon signature: VRCUdonCommonInterfacesIUdonEventReceiver.__ctor____SphereManager

[cold raft]

yeah i dont think you can do it like that, but if the other object is udonSharpBehavoir that is attached to an object, you can retreive a reference to that behavoir by using GetComponent<SphereManager>() on the object its attached to

[wanton palm]

yeah I thought about that but I wanted to avoid it cause I'd rather SphereManager be a singleton

I'll think of something else, thanks

[cold raft]

well if you put it on a single object it will be the only instance right

[wanton palm]

gonna have several spheres objects so I'd need to put one per each

I'll see if I can get around using .Find to get one sphere manager that exists in the hierarchy but calling it from sphere

[wraith citrus]

And I want Udon can some what "Get" the username of a player who just joined the world, and piece together the video link and the user name and make it looks like this: domain.com/playername, and send this link to a videoplayer

I read the full docs but nothing talk about the "text processing"

kinda confuse me

Wouldn't you just need to add the strings together?

[plush stump]

I should use IsValid from vrcplayerAPI not Unity.IsValid to check if player exist right?

[wraith citrus]

yeah! Could it do like Variable replacement?

[indigo finch]

playerAPI.isvalid doesn't work if there is no playerapi to check. do utilities.isvalid instead

[indigo finch]

yea, they are just placeholder strings. grab any strings as inputs will be fine

[wraith citrus]

ohhh Thanks, I finally know how to make my advanced player

[indigo finch]

Nice!

[wraith citrus]

Great. I've been thinking about how vrchat can submit user names to my server, so that players from each country can enter the same world and see videos with different contents

It can also be combined for advanced functions

@indigo finch may I add you and ask you for some little help?

[plush stump]

That's what I used before, just replaced it with playerAPI.IsValid

I'm bit confused...

[indigo finch]

would depend on the context too. would need to see more of your code to see where it might be going wrong

[plush stump]

which should be use before I use the VrcPlayerAPI to make sure it is not null?

I think they both works?
