[formal ledge]

okay thank you

[arctic scarab]

how i edit variable of other script

[valid oar]

Well, if you can manage to phrase that as a question related to Unity or the VRChat SDK, then maybe we can assist but I don't know what to do about general confusion.

[chrome mural]

if need anyhelp ill ask okies?

[formal ledge]

im getting this error on every udonsharp script i have, including udonsharp scripts that i didn't write

[valid oar]

That will happen if UdonSharp is messed up. I would just get rid of creator companion and install Udon Sharp the normal way if you can but I don't know if there is a way of fully excising the creator companion once it's there. Maybe ask about that in #creator-companion

[formal ledge]

oh okay

i dont rememver doing anything with an UdonSharpProgramAsset

[lament valve]

Is InvokeRepeating not allowed in U#?

[valid oar]

I meant asking if it was possible to remove the creator companion but I guess if you can find a fix for the Udon Sharp stuff without doing that, then that's ideal.

[valid oar]

It's not mentioned anywhere in the api documentation so I assume it is not. https://github-wiki-see.page/m/MerlinVR/UdonSharp/wiki/vrchat-api

[scarlet lake]

Is there any quest/pc video please that I can use for like music that don’t have a lot big memory

For a world

[formal ledge]

oh okay

[fossil moss]

@wind atlas here's the final result, many thanks

[formal ledge]

yeah i just don't know how it's breaking on line 1

[wind atlas]

Nice. So the slider affects everything inside?

[fossil moss]

yea

[wind atlas]

Looks pretty good.

[fossil moss]

its as basic as it gets

[valid oar]

If the compiler isn't working properly, it's not going to be able to compile the first character.

[formal ledge]

hm..

Okay, so... it somehow started working

I didn't change anything

I did have to remake the project though

but nothing in it changed

[valid oar]

🙌 Sometimes it just works out that way.

[hollow folio]

Is there any reliable way to detect when a video player starts playing and stops playing?

Looks like I can query "isReady" and "isPlaying" but I'm not seeing any push style functions for them to trigger scripts elsewhere on end.

[chrome mural]

ok im getting different errors

[valid oar]

Did you delete your Scene Descriptor and replace it with VRCWorld?

[chrome mural]

yup

i think

it loaded up the test world but wont let me publish it

[valid oar]

Post an image of your hierarchy

[valid oar]

I don't know what VRCSDK is but its isn't VRCWorld as far as I know.

[chrome mural]

how do i get it back

[valid oar]

How do you get what back? You just drag it in. Do you even know what VRCSDK is and why it's in your scene?

[chrome mural]

its what i used to use with my first world

[lament valve]

How can I get SendCustomEventDelayedSeconds() to work properly? It just executes once

[arctic scarab]

anyoneee

[valid oar]

Okay, well, I don't know what it is, can you open it in the inspector? I'd just get rid of it if you don't know what it's doing or why it's there.

[arctic scarab]

how i edit other script variable

[valid oar]

Have you tried this? I don't know but it looks relevant. https://www.youtube.com/watch?v=n7Y4Bn1UZ2w

[chrome mural]

should i start fresh

[arctic scarab]

dont understand this

ah it different one

[valid oar]

Well, you still haven't done what I told you to do as far as I can tell but if you want to start from scratch and likely run into the same issue, then that's your call.

[arctic scarab]

does it require this weird custom string

also it requires pre defined right

drag dropped reference

[chrome mural]

its jjust acting like its not there

[arctic scarab]

its not exactly example i wanted

[valid oar]

So you're telling me you brought VRCWorld into your scene and it's there but the inspector is just hiding it?

[arctic scarab]

how i change this string from other script

[valid oar]

I don't really know, sometimes one tutorial won't be exactly what you need so you need to pull knowledge from multiple sources but I haven't done what you're trying to do so you've got me.

[outer gazelle]

As I had to figure out on my own (no clue if it is documented anywhere), the End, IsReady, isPlaying only work if the Udon script is set underneath the the videoplayer component.
So the gameobject has to be both videoplayer and main script, if you aren't doing something like I am and purely using it for music then using custom events would be your only way.

I don't understand why you can't specify which videoplayer you want to detect events from, but you can't.

[hollow folio]

More sad limitations. Alright, cheers @outer gazelle

[arctic scarab]

i just use find for this how to do it easy way

[chrome mural]

chuff it im gonna make a party train

[outer gazelle]

Yeah, at least it could have had a tooltip explaining it.

[arctic scarab]

name in ""

[chrome mural]

Where is vrcworld?

[arctic scarab]

cant see shit

its not necesary pretty sure

[chrome mural]

ffs it didnt save

[tepid salmon]

maybe sobody know how to get the curent pick up to drop? it work only for the 1 pick up not for the rest.

[arctic scarab]

if works just for 1 it either loops over the same object or loop lenght is 1 for some reason

[valid oar]

I thought you said you already brought VRCWorld in but now you say you don't even know where it is. You'll figure it out.

[tribal meadow]

I'm still a bit confused on how I should link up these two items...Trying to make a slider that adjust the hue of a particle effect

[lament valve]

Doesn't change anything :/

[arctic scarab]

dont use nameof shitty

[lament valve]

[arctic scarab]

wait

does it not run at all

or just run once

[lament valve]

Just once

[arctic scarab]

bruv what you expect you put it in start

put it in update

[lament valve]

Tried it, just floods the logs as a normal Update() function would

[arctic scarab]

yes because you dont made any filter for that

if you dont have any specific function you want to put sendcustomeventdelayedseconds in you can just make own timer

float a = 0f;
void Update()
{
a += Time.deltaTime;
if (a >= 1f)
{
a -= 1f;
Debug.Log("second passed");
}
}

[tribal meadow]

would this be correct?

[lament valve]

Worked; thanks!

[chrome mural]

ok its uploaded but when i launch the world i get sent to home

[arctic scarab]

if you have something heavily unoptimized it will kick you out

[chrome mural]

how do i deal with optimize things

[hybrid nacelle]

https://cdn.discordapp.com/attachments/845599906751971398/993162440340672513/unknown.png

Hmm, I'm mega confused, in this screenshot at left is Sublime Text , at right is Visual Studio 2019 (16.11.16).

But everytime when i typped GameObject in VS... whole script was broken but when i did exact same thing in Sublime Text... everything was working correctly in Unity.

That was tomorrow but ....Today... it just works in both.. im confused. I did zero changes in VisualStudio and it fixed itself.

Still somehow VisualStudio see everything but not that from where is GameObject... it still stays white. Should be cyan, i really dont know why VS cant see reference for that.

But for now it looks that instaling UdonSharp not trough Vrchat Creator Companion, gives stable project. Creating project trough companion, gives kinda weird behavior.

[indigo finch]

believe so. you just need to have an event that determines when this part of the script will play. perhaps add a custom event, that gets called when the slider moves

[hollow folio]

Is this normal in test mode, or are these actual breakages?

[indigo finch]

or broken. try playtesting in cyanemu or clientsim, and see if it says anything. also see if your computer is chugging like crazy

[indigo finch]

nope, not normal. if it all playtests fine though, then you can just ignore them. might come back to bite you later though

[indigo finch]

had this issue earlier this week rebuilding my computer. Can't quite remember the fix, but I believe I had to link VS to unity or something like that..

[indigo finch]

VRChat Examples, Prefabs, though you probably already found it.
btw, windows key + Shift + s is your friend for screenshotting only part of the screen

[hollow folio]

Works fine in CyanEmu (the errors don't pop up at that point) but doesn't work properly in Local Test mode. Can't understand how it's breaking on the proper build unless it's wrongly stripping them out for some reason?

[indigo finch]

so it's just not building properly or something... The error message you shared doesn't really say much, other than something it relies on failed. scroll up and look at either the start or end of the long string on error messages to see what truly broke

[hollow folio]

So this is from the top, none of these really look like they'd be responsible for the U# cascade of failures from my limited understanding.

[indigo finch]

honestly, assuming your not using the companion app, I would uninstall your sdk and udon#, and reinstall them both (sdk first). also, just checking, but you are using cyan emu and not client sim right?

[hollow folio]

Sorry, ClientSim, the new one. I keep confusing which is the new one and which is the old one.

[indigo finch]

Client sim is the new one. Wouldn't recommend using it without the companion app

[hollow folio]

I'm loading the SDK and everything via GIT so I'm basically doing it that way anyway.

It was fine until a day or two ago, I'm not sure what's triggered this.

[indigo finch]

an update to one of the components perhaps? Pretty typical unity problems if so

[hollow folio]

Nope, I've not updated anything otherwise it would make sense. Not sure how I'd trigger something like this without either something corrupting, or throwing something else into the mix though.

[vapid whale]

Hi! I'm currently trying to make a VRChat world for fun but i end up with some problems! I already tried asking for help, and nothing really worked! This problem has been happening the past 2 days now, and i dont know why... Anyone might know why this would be happening?
Someone assumed i didn't had Udon, which i'm pretty sure i did! It happens when i press "Build & Test" Any help is appreciated:) Sry if im at the wrong place!

[coarse parrot]

Does it show any error in the console?

[vapid whale]

@coarse parrot Having some problems with it atm
But yes, this is what popped up every time i tried

[coarse parrot]

Find your object Cube (6). You haven't assigned source code to it.

[vapid whale]

@coarse parrot Aight, let me try and do smth real quick!

I will quickly make another project, seeing that, that one got completely destroyed! Sry for wasting your time!

[vapid whale]

@coarse parrot Doesnt seem im running into the problem atm, created a new project and got no problems so far!
I can tell it started happening after i tried making a mirror that could be turned on/off... If i do happen to get the problem again, what should i do? If you know ofc:)

Appreciate the help doe!

[coarse parrot]

Always read error in the console. It won't be the same every time. Different errors require different solutions.

[vapid whale]

Aight, ill assume its smth ill get used to, seeing that i just started on unity n all!
Thanks doe, much appreciated!

[cosmic cradle]

Does anyone have udon code for a dance floor?

[arctic scarab]

how to detect if player is on vr or not

[sweet star]

Hey! I'm having an issue with UdonSharp. I'm using the Creator Companion, and have added U# to my project. However, when adding any prefabs that require U#, I get errors implying U# is not in the project. How would I go about solving this?

[arctic scarab]

remove/reimport all unitypackages

[indigo finch]

I would ask in #creator-companion. As the sdk is in a different location, you can't just drag and drop them in anymore afaik

[indigo finch]

probably a lot easier to do this as an advance shader, or an animation. Udon would have too much processing overhead anyways. Regardless of the method, it would be very different depending on your model and whatnot

[indigo finch]

PlayerApi.isUserInVR()

[grand temple]

Make sure you're calling that on a playerAPI that exists like networking.localplayer, not just the raw VRCPlayerApi class

[chrome mural]

i was its only cuz my screenshots dont like to work

[arctic scarab]

like what

[indigo finch]

Networking.LocalPlayer.IsUserInVR()

[wicked forum]

given that "static fields are not yet supported on user defined types", is there another way I could implement a singleton?

I tried using Camera.main but that seems to also be missing

[grand temple]

Have an udonbehaviour somewhere with a unique name, and have your other scripts find it on start with Gameobject.Find

[wicked forum]

that sounds inefficient

[grand temple]

only if you don't cache it

[grand temple]

Use Networking.LocalPlayer to get information about the localplayer. You can do things like get the trackingdata of the head if you want where the camera is

[wicked forum]

I don't really care about the camera, I was just trying to use it to reference an arbitrary object

[plucky kelp]

anyone know if there's a way to have https://1029chris.gumroad.com/l/vrchat-rc-car not parent itself to world root? It's causing object desync between platforms. I parent the prefabs under an object, when I build and publish, they re-parent under world root.

[plucky kelp]

If you don't know what I mean about object desync.

Quest picks up a ball... PC people see them pick up a tedy bear thats on the other side of the couch

PC person pickups a pen, Quest sees them pickup all of America :kek:

[hybrid canyon]

your object hierarchy needs to be identical between both platforms

[tribal meadow]

Thanks, still figuring where to attach that to, but hopefully close now

[whole garnet]

Hi, is there anyone knows how to change a parameter from another script in Udonsharp? Because I am looking to make an elevator, the interactOverride is on the button of the control panel to call the elevator coming , however it seems the static bool isn't support in udonsharp and method initialisation isn't support as well.....

[deep silo]

were you able to resolve your issue? as some suggested putting it the right layer is important, and adding a UIShape component is also important, I've worked with UI in unity quite a bit so let me know if you have any more issues.

[lament valve]

Yeah, everything's been sorted

[tacit harness]

Is there a way in udon graph to stop/interupt a udon script from running at any point

Like i send a interupt even and it just stops the previous flow progress ?

[fiery yoke]

Theres a little technicality with that. You can disable the UdonBehaviour component, however that only removes it from Unitys event loop. It will still receive and execute custom events.

[tacit harness]

So there is no way basically to interupt a ongoing even

Like it is running and i wanna stop it in the middle of the code , that isnt possible im guessing then right ?

[fiery yoke]

That depends what you want exactly...can you like show what you currently have?

[tacit harness]

I dont have anything specific rn

But lets say i send a delayed even with a 5 second delay
But now something happens and i want the even to restart and the even not fireing anymor after those 5 second but i want it to restart and run down the 5 seconds again

[fast heath]

i am having issue with this error

[scarlet lake]

can somebody tell me how to properly make music in a world? I made a monster for my world and it has a sound on it but the voice is hearable from everywhere in the world in unity and in game when testing it KINDA works but its waaay too quiet even at full volume.

[whole garnet]

ahhh, G'day guys... is there anyone knows what should I do now...?

[hollow folio]

Make sure it's set to 3D and spatialised, otherwise it'll just be stereo in your head

[scarlet lake]

Ill try it. thank you

[limber solstice]

Is there any way to get the scale of player avatar?

[whole garnet]

this looks wired

unable to upload

[scarlet lake]

@hollow folioI turned on spatialize but I still hear the sound from everywhere

[hollow folio]

Did you also slide the bar over to 3d from 2d?

[scarlet lake]

what bar? I only see a drop down for 3D settings

@hollow foliothis is what I see

[hollow folio]

Discord doesn't let me zoom in enough on mobile to see. You need to make sure spatial blend is 3d.

[scarlet lake]

Ohhhhhh

I just did. hopefully that works

[candid hill]

As someone who has never made an avatar but would like to, how would you go about making an avatar and porting it onto the quest? Would you just upload the avatar to a linked PC account and it’ll be there on the quest version?

[scarlet lake]

how can i make my world super optimized

[outer gazelle]

Most important part, bake the lighting, real time lighting is really performance intensive.

Can be good to know that if you intend to port it over to Quest, then you should try to keep transparency to a minimum and even though it is allowed on PC, if you want to something to be super optimized then you won't want to use transparency even on PC.

And if the world is high poly then you will definitely want to create a separate mesh to work as its colliders, basically the same mesh, but heavily decimated, the greybox mesh can work well, assuming you didn't change anything major.

And then it is the same stuff that applies to avatars, few meshes and materials, and no poorly optimized shaders.

[outer gazelle]

Wrong channel for this #avatar-help.
But basically, the versions (Quest, PC) are treated as almost separate thing, you can have a completely different avatar for your Quest version, all that joins them together to be treated as a single avatar is a thing called blueprint ID, which gets assigned to an avatar when it has been uploaded once, you then take that and paste it onto the Quest or PC version, depending which version you uploaded first.

[wicked forum]

What does "Could not load the program" mean? Suddenly none of my scripts are working

I'm also seeing a bunch of "Empty UdonBehaviour found" warnings

[lament valve]

Is there a certain terminology for these things?

[lament valve]

Ouchie, last time that happened to me my project was corrupted. Unpopular solution: Delete the Library folder with Unity closed and relaunch

[valid oar]

Udon Sharp scripts?

[mighty fjord]

I believe those assets are ScriptableObjects

[lament valve]

So basically, creating a U# script creates these. You aren't really supposed to touch the left one from what I'm told and the one on the right is the raw script itself.

I like to stash all the ones that look like the left in a separate folder

[mighty fjord]

You can call them the UdonSharpProgramAssets if you want a more specific term I guess

[lament valve]

Sounds good, I'm always afraid of missing out on a ton of essential knowledge

[valid oar]

Yeah, the one on the left is the compiled script that Unity can work with, the one on the right is the code you edit which is then compiled to get the thing you can just drag into your Udon Behaviour component.

[lament valve]

Thanks!

[wicked forum]

I ended up reverting all my scene/prefab changes and redoing them, which seemed to resolve the issue

didn't think about Library so I don't know if that would have helped

[vapid badger]

so UsharpVideo didn't work? I tried just using the normal soundcloud url for a track in VideoTXL and it also didn't work...

[outer gazelle]

Nope, only the standard default one worked for me.
Doesn't make any sense to me why seemingly every non-default player has this problem, if it was getting caught by the filtering system then it should be displaying a specific error message, but it instead just gives a general error.

[vapid badger]

Yeah, I get "Source Invalid or Offline" message.

[valid oar]

That's where the Get IsLocal branch comes into play https://www.youtube.com/watch?v=1QSbuwij_Xc

[valid oar]

Creator Companion in general is a problem right now, not recommended.

[valid oar]

Isn't ClientSim basically just CyanEmu?

[indigo finch]

Yes, but CyanEmu hasn't been updated for a while now, and is missing functions like playerApi, respawn, as well as some other bugs that never got ironed out beforehand. Also gives you a humanoid model instead of just a capsule

[torn shuttle]

I'm making a flying / acrobatic race world- when players pick up a lot of speed and glide downwards their avatars play the falling animation. Is there a way to turn off the falling animations for all players in my world or set the speed threshold higher?
(here's the test world if you guys wanna play around in it, https://vrchat.com/home/launch?worldId=wrld_67b746a7-8100-4fd2-8294-864cb8594a1b )

OOooOOOoo never mind- I found VRC Station script and I may be able to do what I want with that
//edit! I did it! VRC Station worked for me!!
I first changed the velocity to -99 and it worked out and cancelled the falling animations,
but then i had an idea to replace falling animations with flying animations. It doesn't seem to play my custom animations so I'm back to disabling the falling animation

[primal bone]

What is the difference between udon and unity and which one is easier to use

[lament valve]

Everyone starts somewhere!
#udon-general message

[midnight beacon]

You can't use Udon alone, Udon is a scripting system inside Unity that you use to add interactivity to your world

Does anyone know what the best way to attach something to a player is? (found CyanLazer's cool package for assigning objects to players, solved 👍 )

[proud cradle]

It seems that there is big difference between player collider for desktop and VR. Is this pointed out anywhere in docs? Can't seem to find accurate description of this but from testing it does seem different, like it's either just bigger or is anchored to headset+ground position

[light bobcat]

How can I attach an udon behavior to players?

[ebon dragon]

I am pretty positive that's not something you can do-- You can, however, create a new empty object that does things with the player

there is a piece of code that lets you get the local player and such

https://docs.vrchat.com/docs/players

[light bobcat]

oh so I can’t just give players a behavior with some variables and functions and then when I need to get something just get it from the player?

[ebon dragon]

not the player game objects, but a single dedicated object can pretty much handle this for you yeah

check the docs I linked ^^' it'll explain

[light bobcat]

thank you

[eternal hare]

what defines the player and how do i lock an object to players?

[cosmic seal]

i want an object in my world to slowly rotate so i made this graph but no dice, what might I be missing?

[outer gazelle]

Purely guessing, but you sure the rotate is done relative and not absolute?
Right now I think all it does is rotate to the position you set in "RotateSpd".

Try doing Vector3 addition with your rotate, that might work, assuming Vector3 has an addition.

[cosmic seal]

oh yeah it does, i'll give that a try

[cosmic seal]

this is my first time using udon and i've been able to do other simple stuff just fine, like object toggles and a scrolling texture, but i just can't figure this out

[scarlet lake]

Does anybody know how to hide a GameObject at first?

This is a very simple trigger system using Udon and it works but with the object already spawned , and I want to make the object appear at first click rather already spawned and triggering to disappear

I'd probably do something like lolicol.SetActive(false) but I've got no idea how to do with Udon graph

[cosmic seal]

wouldn't you just untick the active checkbox?

so it's inactive when the scene starts and can be activated by the toggle

[scarlet lake]

Oh my

How did I not think of that

[cosmic seal]

glad i could help

meanwhile i'm still bashing my head in trying to figure out object rotation lol

[scarlet lake]

That solved my problem 🤦‍♂️ thanks a lot..

[scarlet lake]

I may not be skilled enough to answer this but this just seems to be increasing the speed parameter itself rather than actually spinning. Probably set the angle to something else than 0?

[cosmic seal]

tried that awhile ago and nothing changed

[scarlet lake]

Oof

[outer gazelle]

One thing to keep in mind, that while I do not know the full effects of it, when having something off by default, it seems to be less optimized, than if it was on. At the very least it would cause a jump in frame time.

I did a similar thing with my map, I wanted a baked day and night so to make one "off" I used animations (default instantly turning it off when it loaded) instead and made the udon script change the parameter I made for the animation.

I followed this guys tutorial to get my head around it and at 11:55 forward he starts talking about how you can lower batches (think are the same as draw calls) by not default hiding it https://youtu.be/VLU6A4JWsWk?t=791

[scarlet lake]

This tip is very informative for what I'm trying to figure out! Thank you for suggesting such method since it could save my badly optimized maps lol.

[outer gazelle]

Had to rewatch that part to get the gist of it again and going from 16 to 400 draw calls would probably be a large problem for any Quest user since they are apparently especially susceptible to high draw calls.

So yeah, this guy got some really good optimization tips

[scarlet lake]

I can definitely tell. Draw calls always become a big barrier when making any worlds for Quest since it's just Android with fairly good GPU

[scarlet lake]

I don't know about optimization but this worked for me

[outer gazelle]

Honestly, what could you even optimize on something this simple.
Only thing I could think of is updating at a slower rate.

[scarlet lake]

Yeah, 10 deg was actually pretty fast so probably adjusting the angle value lower would help

[outer gazelle]

Maybe an animation would be more optimized.

[cosmic seal]

i'll give this a try

omg finally

thanks a ton

[scarlet lake]

loll my pleasure!

I'm glad it could be a help.

[cosmic seal]

still have a problem

no matter which Vector3 value I set to 1 (and the others 0) it always rotates on the same axis

they actually don't seem to be having any influence at all, even if all 3 values are set to 0 it's the same

[outer gazelle]

That shouldn't be I literally just had fun having it rotate

Also, not entirely sure one should be using update for this, the variable speed could get noticeable.

[scarlet lake]

I'm trying to think of how to compensate the angle value getting overly larger by checking if the angle is over 360, but I'm not sure if it'll be really healthy for the performance

[cosmic seal]

it only rotates on my end if it's a v3 float space type

without it it doesn't rotate at all, and with it it ignores all axis input

[scarlet lake]

Just to make sure; is the Dice you're trying to spin an ordinary GameObject?

I've tested with a 1x1x1 cube and it seems to be working for both Mackandelius and mine so I wonder

[cosmic seal]

is an imported mesh not a gameobject?

[scarlet lake]

I believe mesh is just a property of a gameobject rather than not being itself

[cosmic seal]

well now i feel dumb because that was the solution lol

i just made an empty and put the model in it and set the empty as the gameobject

[outer gazelle]

Why would that work

Why does that work

[cosmic seal]

idk but it does lol

[scarlet lake]

It's called programming

We don't know why but if it works it works

Sadly I'm not familiar with whole mesh and stuff but I wonder how that'd make the object stuck unless attaching to an empty gameobject

[manic yarrow]

Really dumb question, how do I set a boolean?

[scarlet lake]

Hey all, I'm curious how the VRCPlayerAPI functions. How do playerIDs look like? Do they range from 0 to the maximum world capacity?

[grand temple]

the first player gets ID 1 and everybody who joins adds 1 to that number. Numbers are never repeated so even if the same person leaves and rejoins they will get a new number. Numbers can go up infinitely

[grand temple]

if you're talking about udon graph, you can hold ctrl while dragging and dropping a variable into the graph

[scarlet lake]

Thank you!!

[thin kernel]

any idea how to make a local box toggle only able to be toggled by the local player instance and not by other players?

[grand temple]

Depends on the event that you're using to trigger this. If it's an interact, then that's already local. Most things are

[scarlet lake]

Isn't this just a local sync thing? Disable any network sync and the cube should be locally toggleable

[grand temple]

you don't need to disable something that isn't happening from the beginning

[scarlet lake]

Some prefabs have some sort of sync script attached, so always good to check

[grand temple]

if it's a pickup sure

that would be the objectsync script

but again, it won't be there unless you add it

[thin kernel]

well perhaps i should explain. i have a local toggle script on a box collider. but for some reason other players can walk into it and activate it foe other players despite it not being designed to do that.

how would i set up the script to not behave like that?

i want the toggle and the collider truly local

[grand temple]

there are some events that trigger for all players but they are not technically networked, like onplayertriggerenter. Because you see the player enter the collider, that gives you the event

so if you're using an event that gives you a playerapi, all you need to do is check if the playerapi islocal

[arctic scarab]

how would i make player trigger oncollisionenter when walking into wall

[grand temple]

oncollisionenter does not happen when a player touches a wall, it's a bit niche since it only happens when a rigidbody flies into and touches the player

instead, I would just recommend putting a trigger collider slightly offset from the wall and then using ontriggerenter

[scarlet lake]

Can somebody help me setting the Y position of the GameObject to player's head with Udon graph? This is what I could do and nothing is happening right now.

[grand temple]

you cannot control the player's avatar, that's protected and read-only

[scarlet lake]

Oh my bad, I'll clarify

I edited the question

[grand temple]

you're looking for the transform set position node then

[scarlet lake]

Wouldnt that require me to set the value for all x y z?

[grand temple]

yes

you can separate them out and construct a new vector to do what you want

or you could copy the position into a new variable with get position, set the y of that variable, then apply that variable back with set position

[scarlet lake]

I'll probably try that. Thanks a ton!!

[manic yarrow]

is there a way to set a boolean without unary negation? I asked about it the other day but it turns out I can't just invert the bool because it's ontriggerstay and it'll just flip back and forth constantly

I tried leaving the input blank and using the checkbox but it didn't seem to work

[grand temple]

there are a million ways to set a bool

really depends on what you want to happen

[ebon dragon]

unary negation really just flips it from true to false or from false to true

[manic yarrow]

It's for an automatic door system

Triggerenter opens the door, triggerexit closes the door, but I want to make it so that if there's anyone in the trigger the door will stay open no matter what

to do that, I've been using a synced boolean that's true if anyone is in the trigger

and that's where we are now

[gentle imp]

Would it work to make a variable for storing how many people are inside the area (and close it when it's at 0) ?

(enter -> +1, exit -> -1)

[grand temple]

that's definitely not something that should be synced, all the clients should have the information they need to handle it independently. Adding sync jut adds latency and room for things to get out of order and break

counting the number of people in the collider is a good way, but be aware that when someone leaves the instance or enters a station while in the collider they won't trigger exit, so it would get stuck open permanently. but that can be fixed by just resetting it back to 0 occasionally

[manic yarrow]

could the boolean idea work in theory?

Right now it's set up so that on trigger exit, it checks if that boolean is false

if it's false the door closes, otherwise it just does nothing

[grand temple]

could work but would need to see your code to see what's not working

[grand temple]

you're using unarynegation but with a constant value, which flips it, so onplayertriggerstay you're just always setting keepopen to false

instead, use a bool const node

[manic yarrow]

Just tested it, now the doors stay open when I exit the trigger

Is it possible that the ontriggerstay is firing after the exit?

I added a debug log just to check, and for some reason it's behaving weirdly

keepOpen is true once every few frames but false most of the time

and despite that, the doors now stay open even if nobody is inside the trigger

[slim hound]

@manic yarrow I would recommend doing this instead

[manic yarrow]

Does it account for people leaving?

[slim hound]

Ah, no.

But easily added

Has to be delayed by a frame as the player still exists when OnPlayerLeft runs

[scarlet lake]

Just a stupid random question - Is it possible to add multiple Udon Graph tabs?

I want to compare with other Udon Graph files and I need to switch between the files since it seems to be impossible to open multiple Udon Graph tabs. I wonder if this is just how it is or I just can't find out

[hollow folio]

I'm feeling like a dumbass. How would I define an array of VRCUrls and then set them? I was thinking private VRCUrl[] _blah; and then setting them via _blah[] = "myurl" (optionally with an int in the [] to specify the array key) but I assume I'm getting this all wrong as I'm not familiar with C#.

Ok, I've actually got that, I just had an error. The issue is setting a URL, as it complains that it's a string, but that's... what a URL is, lol.

Specifically Cannot implicitly convert type 'string' to 'VRC.SDKBase.VRCUrl' Assembly-CSharp

[chrome mural]

can someone give me a hand animation doors to open and close

[tropic canyon]

You can't construct vrcurl's

at runtime

just do a public vrcurl[]

[hollow folio]

This is in the editor, not at runtime.

[tropic canyon]

and set it in inspector

by runtime I mean when running the code

[hollow folio]

Hmmm, how do other playlist systems work then, where they appear to have hundreds of thousands of things preconfigured?

[tropic canyon]

they might use editor scripting to set them in the editor

reading in a text file and setting the serialized field

or you can do it manually

[ebon dragon]

if I change some values in an udon script, will the world still be crossplay?

[valid oar]

Yes but then that would be different in the 2 builds. You should publish to both platforms after making changes for them to be the same.

Once you publish it for both platforms, it will stay available for both platforms regardless of what you do but if you start making to changes to one and not the other, it might be hard for people on either platform to interact with the other.

[solar crater]

im really confused on how SendCustomEvent works. when calling in another script a function i just end up with errors.

[wind atlas]

What is the error?
Btw, in U#, your line of code is the same as: objectGen.RandomizeObjectPositions()

[solar crater]

tried these aswell

i think it just cant find the function because its in another script

[wind atlas]

What type is objectGen?

I'm assuming objectGen was also defined in U#, which means you can just press dot and intellisense should show you RandomizeObjectPositions.

[solar crater]

ObjectsGenerator

its a script

[wind atlas]

Yeah, so does it appear in intellisense?

[solar crater]

nvm unity yeeted the script refrence

for like no reason

[wind atlas]

I guess I should've asked for you to open the error details. It should've shown you that the object instance is null.

[solar crater]

yhe idk why, unity just yeeted it so it was null

[wind atlas]

Yes, you can change it. As far as I know, only the hierarchy structure matters. However, as the other person noted, if that value has high impact on the scene, then people will start to see different things.

[wind atlas]

Have you tried using the animator for that? In the script, you can have a reference to the animator and just call "SetTrigger" or one of the other methods to interact with the animation variables.

[tropic canyon]

the function is only "RandomizeObjectPositions"

which you can also access by doing a

nameof(YOURCLASS.RandomizeObjectPositions)

probably

if you work with u# just call the function and u# will translate it to sendcustomevent and set the variables for the arguments if it has any

[solar crater]

yhe the issue was that unity threw out the refrence so it didnt work.

[arctic scarab]

how could i

load object names from host

and use them for everyone who joins

[chrome mural]

where do i find it iim not used to animating

[hollow folio]

How do you convert a string to an int? (given that it says it can't cast on it's own)

[valid oar]

Are you getting some sort of string input from the player? In C#, you would need a parse method but I'm not sure if that exists in Udon.

[hollow folio]

int.Parse(_buffer); seemed to work?

(with "_buffer" being the string)

And yeah, it's input from the player but it's a string and I need an int for an array.

[valid oar]

If it worked, cool. That's not included anywhere in the api documentation but maybe it's incomplete or the existence of certain functions is just assumed to exist.

[wicked forum]

are pickup objects implicitly synced or do I need to add the other component?

also is deactivating GameObjects synced?

[valid oar]

You need to add the ObjectSync script to an Udon Behaviour component, it's included in the SDK. It really depends on how you handle your deactivation as to whether it will be synced. If you just have an interact and a set active node, it won't even be global.

This method should be synced. https://www.youtube.com/watch?v=19HMJaHGtqw

[arctic scarab]

i want on join copy object names from host and paste for joiners how i do it

[valid oar]

On join copy object names? What sort of object are you copying? And where is this being pasted? I doubt I'll know the answer but I don't understand the question.

[arctic scarab]

because i dont know how to pass them through network event

i have object that holds player slots

and i want it to update whenever somebody joins or leaves

so any example of synced name change

[indigo finch]

Players name's don't normally change though...

[indigo finch]

int, ToString node for graph; or 123.ToString() for sharp

[hollow folio]

Wrong way, but it was parse i needed.

[wicked forum]

Is there a way to change interaction priority or something? I have a button that's really hard to press because it keeps trying to pick up pickup items instead

[valid oar]

You can change proximity on interaction but it seems to have a lower limit that is still pretty far away. I would recommend either adjusting the placement of your button or pickups or adding some sort of toggle to the colliders so you can alternate between them.

[arctic scarab]

or do raycast yourself

[arctic scarab]

anyoneee

[scarlet lake]

how do i get the "new user" rank, how many hours do I need in the game or how many friends do I need to add, I need help

[valid oar]

It varies but not many. If you hop in occasionally, you'll probably get there in a day or two.

[scarlet lake]

i got like 7 hours tho... is that not enough?

[tropic canyon]

This is not the channel to ask such questions

[valid oar]

Over what span of time? I don't think you can just play a bunch all in one session and get there. They don't make the requirements public.

[tropic canyon]

[scarlet lake]

which channel is it?

[valid oar]

Also true, you could ask in one of the general chats but no one can give you a firm answer, really.

[tropic canyon]

#user-support-old probably

[wind atlas]

You can probably find plenty of tutorials as it's an essential Unity feature. You can even animate in blender if you are more comfortable with that. Once you have the animations, you can do something like this: https://www.youtube.com/watch?v=M7pN8QYTGBQ

[twin lake]

Is there a way for udon to generate a 50/50% chance to spawn an object in the world when a player joins but its only visable for that player?

[fiery yoke]

Yes using Random.Range

[twin lake]

that looks massively complicated lol but thanks that gives me something to work with

[fast oracle]

I don't know if this question belongs here (new to the discord, Hello 🙂 ) but I'm having some troubles with fps problems in vrchat through the desktop. Is there anyway for me to configure this, even in game?

[chrome mural]

how can i make a simple toggle switch form a model

[lament valve]

A question like this is best asked in #user-support-old (for future reference: this chatroom is for world building with udon)

There are multiple things you can do to increase fps, such as strengthening your safety settings, performance options, and limiting bones in advanced safety.

[indigo finch]

I did it as a short, but basically this: https://youtube.com/shorts/JLepggh5B1U?feature=share

[chrome mural]

thanks brudda

[arctic scarab]

anyoneee

[dawn forge]

Anyone know where the UdonSharp examples are located if the Unity project was generated by the VRC Companion app?

[arctic scarab]

what kind of examples

[chrome mural]

is there a way of how i can put the train on sliders and make it move as an entity

[valid oar]

Just parent all the stuff you want to move to the main structure or even an empty game object and then move that and everything should come with it.

[solar crater]

Idk if anyone else has had this happen to them but suddenly my unity is executing code in a wrong order.
I have 2 scripts
Script A and Script B
A runs start > then a function > another function > and finnally a function that calls another function in script B
B runs important stuff in start > gets activated by function in script A
however rn the last function in script A is being called BEFORE the start function of script B.
im not sure how to fix this, anyone got any idea's why my start function isnt running before anything else?

NOTE, the correct order does work in game but only cocks up in editor runtime

'proof'

both these debugs are on the same script

[eager fulcrum]

How to deal with this udon problem?

[pallid roost]

Did an update change the way OnPlayerJoined works in the last month or so?
I have a list of objects that are VRCInstantiate and each of them listen for a username OnPlayerJoined to trigger a behaviour.
It used to work perfectly and then after an update i believe it just stopped working

i remember reading about some changes to the VRCInstantiate call but it didnt mention anything about breaking registered events on the objects

[indigo finch]

You could do it as an animation. but it sounds like using Cinemachine dolly track, that can be used to make an object follow a set path, would be more appropriate here:

[arctic scarab]

why this doesnt run

    public override void InputMoveHorizontal(float value, UdonInputEventArgs args)
    {
        Debug.Log("walking");
    }```

[coarse parrot]

Have you put in a game object?

[arctic scarab]

yes

ok fixed

[chrome mural]

ok ill test with that thx

ok so how do i attach my train to the dolly and then how do i edit the line

[topaz jetty]

you need to use new VRCURL("youtube.com/watch?v=videohere"), and vrchat doesn't allow you to create URLs at runtime so you can't put a string variable in the place of the string

which also means you have to put your URL in a variable, and the value can't be assigned in a function/method/event

it must be inside the class

so then it's constructed at compile time

[hollow folio]

Thanks, someone else replied in a different server but yeah, this was what I was looking for.

[indigo finch]

First you need to make a dolly track (cinemachine Smooth Path) for it to follow:

and then you need to make a dolly cart to follow that track:

[arctic scarab]

how to claim object ownership

so synced object will be synced for everyone

[indigo finch]

networking.setOwner

[arctic scarab]

anything more like name

also is it need to be run by host or anyone

[tribal meadow]

something just wigged out with udon, not sure what happened but I'm getting this error and Unity wont' display the graph of what I'm working on anymore. Other scripts are fine. Completely rebooted, still happening

[arctic scarab]

usharp better lol

[tribal meadow]

I'm not a programmer

[arctic scarab]

not either

[tribal meadow]

I've been struggling to get this stupid thing to work for over a week

[arctic scarab]

but graphical programming kills even more

[tribal meadow]

wish there were more prefabs available for udon

[arctic scarab]

magic of programming is copy pasting everything

[tribal meadow]

I have no idea what this crap means...

Looks like I've lost all my work on this anyway

[arctic scarab]

see

and in usharp it would be saved in text file

[tribal meadow]

USharp should just be part of the SDK IMHO, not an add on. Everything uses it.

[ebon dragon]

with physics.raycast, how do I make it only check specific layers?

because when I do this it for some reason starts to exclusively check the IGNORE RAYCAST layer

same if I use layermask.nametolayer

I am going insane over this

[indigo finch]

22 in binary = 10110, so a layer mask of 22 will check layer 1, 2 and 4

[tribal meadow]

I can't figure out how to get this thing back

[ebon dragon]

omg you have no idea how much this clears up for me

<3

[arctic scarab]

any example of thiiis

[indigo finch]

was ages till I found out about this ^^

[arctic scarab]

also what is requestserialization

[indigo finch]

I recommend geting visual studio

[arctic scarab]

i mean it doesnt tells me what it is

[signal yarrow]

https://udonsharp.docs.vrchat.com/vrchat-api#methods-5

here

[indigo finch]

if you can't read scripting tool tips, I recommend using graph, as it shows/ names the required inputs on each node

[arctic scarab]

this

[indigo finch]

is the function you want

[arctic scarab]

it was mentioned often when talking about transfering ownership

[indigo finch]

has nothing to do with transferring ownership. it is used to tell the script to sync all the variables, when using manual sync instead of continuous

[signal yarrow]

you were probably miss-understanding how the owner ship works

[arctic scarab]

ah great i hold all of the sync in object not variables

[ebon dragon]

So how do I actually bitshift inside udon? I can't manage to get it done ^^'

[indigo finch]

never had success myself. at this point i just use a binary lookup

[signal yarrow]

How could I sort objects, because anything like Array.Sort or List.Sort were not able to use

I rather not to write a sort method by myself 😅

[chrome mural]

ok not going ok anymore it just killed my world

[wind atlas]

I don't know if that helps, but I've used this thread multiple times now for figuring out layer masks: https://answers.unity.com/questions/8715/how-do-i-use-layermasks.html

Scroll down for some really nice images.

[topaz jetty]

I think you pretty much have to

[hollow folio]

I'm probably doing something stupid, but this doesn't seem to fire (for anyone, even the person triggering it). It works fine locally if I use a SendCustomEvent instead of the Networked version... but it doesn't even fire locally as-is.

(the bool value doesn't need to be synced as users set it locally when the process runs, I just need the whole thing to trigger on everyone)

[topaz jetty]

do you have the udon behaviour's networking mode set to either manual (reccomended) or continues? I'm pretty sure networked events won't work if it's set to none

also check if you're not mixing any networking modes on the same object

[hollow folio]

It's on Manual

This is the only behaviour on the object.

[topaz jetty]

why do you have the door open variable in your udon graph? you're setting the variable in your animator, not in udon

make sure you have a parameter called DoorOpen (with capitalization) in your animator which should be on the same object as the udon behaviour

[arctic scarab]

does transform always uses same path even if different players have different object names

[grand temple]

Not quite sure what you're asking, but if you mean storing a variable "Transform" then it doesn't go by path, it's just a direct reference to an object. And you can't sync a Transform variable so other players are irrelevant, they'll all find their own references however you choose

[arctic scarab]

what if i pass transform through synced function then

[grand temple]

You can't

[arctic scarab]

i mean its saved locally

[grand temple]

yeah

[arctic scarab]

from variable

and i can use any variable inside

so i wonder what will other players have in global

[grand temple]

but you can't set a Transform variable to be synced

[arctic scarab]

yes so i want every player load it locally

[grand temple]

right, so if you do that by making it a public variable and dropping it into the inspector before you upload the world, then everybody will have that reference and it'll just work

you could also use Gameobject.Find or Transform.Find or Transform.GetChild to navigate to a specific transform, however you want to do that. You can totally sync a string that represents a path and then make your own code that navigates that path to find a specific transform, however you want to do that is up to you

but you cannot sync a raw transform, because it is not serializable. It is a reference

[arctic scarab]

so lets say

Transform a;
SendCustomNetworkEvent(NetworkEventTarget.All, "test");

void test()
{
a.GetChild(0)...
}

will every player have same a

[grand temple]

well that code wouldn't be assigning anything to a, so no. But if it did assign something to a then yes

[arctic scarab]

dynamically too?

Transform a = gameObject.Find("something").transform

[grand temple]

yeah, however you want to do it

[arctic scarab]

i was 90% sure dynamic variables arent passed by udon

so had get static ones somehow

[grand temple]

what?

[arctic scarab]

wait so even if object has different name it will still point to same transform

[grand temple]

uhhhh I have no idea what you're getting at

if it has a different name then it's a different transform

[arctic scarab]

no

[grand temple]

unless you renamed the object at runtime

[arctic scarab]

if i changed name

but not changed transform

yes i renamde

[grand temple]

well transform is effectively just a component on a gameobject

[arctic scarab]

i store hp in names

[grand temple]

why?

[arctic scarab]

because yes

[grand temple]

what

[arctic scarab]

udon is shitty so i prefer names

[grand temple]

I uhh

I think you're on your own with whatever you're trying to do

[arctic scarab]

also i effectively removed as many scripts possible from my map which improved loading time by 2500%

[hollow folio]

I do. As I said, the whole thing works if I do a local custom event call, it just doesn't work when it's set to custom network event. That variable is there because I was doing it a different way in the distant past and never got rid of it.

[arctic scarab]

meanwhile another thing can i make vrc synced object sync only position and not rotation

because i have spinning animation and it lags out

[grand temple]

no

[arctic scarab]

then local spinning maybe

[grand temple]

yeah

I would recommend using manual sync to just sync the animator variables instead of trying to sync the position of the object

[arctic scarab]

oh fuck no animator

[grand temple]

well whatever you're using to animate it

[arctic scarab]

then i can make just another object inside object and spin the child

then it wont be synced

[hollow folio]

The collider and animator are both on the door which is the same object as the script itself is on (hence the self references in the graph).

[topaz jetty]

I have no clue then, it should work fine

[scarlet lake]

does anyone know any quest/pc video players

[hollow folio]

I'll mess with the prefabs in case it's lying to me and something's being silly. Thanks for confirming though.

[arctic scarab]

something not right

it dont seem be synced properly

or to detect transform at all

ah i was making 2 separate variables

how i check if im the sender of the network event

to put line of code in remote event that runs only for the sender

[ancient mountain]

Can anyone help please, I have two Udon Behaviours (Graph), one has an interact event with gameobject, and I'd like to send and receive that interact event on another udon graph. No delayed event, no networked event, just a straight custom event for now.

I've followed bush's tutorial that I believe is exactly what I want from the first minute, but I think I'm missing something: https://www.youtube.com/watch?v=0yMwbl25k3c

Attached is the two pictures of the graph of both scripts

[grand temple]

that looks like it should work, what's happening?

[ancient mountain]

Nothing at all, I'm trying to log the interact event from the other udon graph just to see if I'm getting it across.

The interact event send graph only has an UdonBehaviour variable assigned as public, and I'm gussing the variable name doesn't matter.

The event receive graph just references the name of the event being sent from the other script, there's no variables defined there.

the only link between the scripts is the name of the event itself, so it feels like it's missing something

[grand temple]

Are you getting any errors in your debug log?

[ancient mountain]

Naww, nothing at all unfortunately, it's as if there's no link at all between the graphs

[grand temple]

Well if there's no link then it should crash the script and you'd see that in your log

[arctic scarab]

okay it actually crashes

i think it doesnt sync properly

[arctic scarab]

it doesnt work when outside of function? only inside?

[hollow folio]

I have a "VRC Unity Video Player" in the scene with a URL in it, but I see this in the log:
[USharpVideo YTDL] Attempting to resolve URL
... now this isn't a USharpVideo player, it's literally just the raw component for the Unity Video Player. Why is USharpVideo trying to resolve the URL? (does USharpVideo handle the VRC Unity Video Player internally?)

[ancient mountain]

I see. I'm not winning with this. Do you perhaps know of a different way to send events between graphs?

[arctic scarab]

send info to object and read from other script

that how i do

[grand temple]

No, that's exactly how you do it. You have something set up wrong. I see that the debug log is set to the version that takes a context, that's a little unusual. Try setting it back to the default version.

also make sure you have an udonbehaviour set in the inspector's public variable

[ancient mountain]

Yeah, I'll show you some pics now.

[arctic scarab]

do i have to define transform locally and cant use earlier variables?

how do i sync string for network function

[ancient mountain]

Your last point about the inspector public variable is what make's me believe there's no link, or instance reference. Because the sending graph only references itself as you see in this pic (it would make sense to link the receiving script there like you would with anything else, but there's no option for that, unless i misunderstand):

And this is all there is in the receiving script.

[grand temple]

Oh, yeah, you see where it says public variables: discholder2_operation?

[ancient mountain]

Ye

[grand temple]

That's the target where you're sending the event to

[ancient mountain]

yeah, the other script

[grand temple]

But you left it blank so it self references

[ancient mountain]

that makes 100% sense buuuut...

[grand temple]

So it's just sending it back to itself, not to the other script

[ancient mountain]

I can't put the link to the second script there

like, the graph it self

I can't attach it

normally you push the button and it brings up the menu to select something

[grand temple]

You're not supposed to, you put in the object that has that script on it

[ancient mountain]

Ahhh

ok, let me try

Yea.. xD

Thank you for clearing that up

it works

🫂

[arctic scarab]

do i need just make regular udonsynced variable

[tribal meadow]

I think I found a bug... If I try to set 'instance' off of the Particles, Set Start Color, it breaks Udon. All the nodes dissappear, and an error comes up in the console. It's unrecoverable as you can no longer see what you are doing in the graph window in Unity

[grand temple]

"particle" is not exposed to udon fully. I think you can kinda do some weird things with them but not much. Given that you're accessing and iterating through a particle system array I think you should be looking for a "particlesystem" node, which is different from "particle"

[tribal meadow]

hmm ok. The slider is functioning, but it doesn't seem to be passing the colorstart value to the actual array or particles, so I'm trying to add that to the instance output to tell it, but not sure what node I would use to do that (that doesn't cause it to crash)

[grand temple]

Have you replaced it with a particlesystem node?

[tribal meadow]

I'm a little lost

As it is right now the slider doesn't do anything, so I'm assuming I have to tell it which particles (particle array) to send the value to, but if I add the particle array to the instance, it crashes

[grand temple]

You don't have a particle array

You have a particlesystem array

[tribal meadow]

I don't understand the difference

[grand temple]

A particle system is a component that emits many particles

Udon can totally interact with particle systems, but it cannot interact with individual particles

[tribal meadow]

right, what I'm trying to get it to do is change the particle systems startcolor

[grand temple]

Right, so you need a node that affects a particle system not a particle

[tribal meadow]

but there are several of them (an effect) so I want to change them all at once when the sliders hue value is adjusted

I guess I chose a confusing name as the variable, but I thought that's what I was doing

[arctic scarab]

is variable guaranted to sync before running remote function if its before in script

[grand temple]

No, it can go either way. You should never rely on using synced variables in a network event for that reason.

[tribal meadow]

so if I do this it kills the graph window

[grand temple]

Right, because you have the wrong node

[arctic scarab]

how im supposed to send stuff from other player then

[grand temple]

So look for a particlesystem set startcolor node

[tribal meadow]

ok

[grand temple]

Include some synced variables that indicate what action you want to perform and then use ondeserialization to perform that action

[tribal meadow]

I guess what I'm trying to do doesn't exist

I'm trying to get a slider to change this value

[grand temple]

well it's not particlesystem.startcolor, it's particlesystem.mainmodule.startcolor

[scarlet lake]

does anyone know any quest/pc video players

[tribal meadow]

OK I think I see...but now I'm not understanding what I use to get the color value into that....

[grand temple]

get rid of the mainmodule get color, you don't need that. Just plug in the color you're creating with hsvtorgb

[tribal meadow]

It seems to want something in between...but not sure what...

[grand temple]

ah, sorry I told you the wrong thing, you need this

startColor isn't just a regular color that can be plugged in, it's a whole special gradient thing with it's own functions so you need to get the startcolor and then change the colors inside of startcolor

so much stuff to deal with

[tribal meadow]

Yeah, I see... this isn't something simple

crosses fingers?

[grand temple]

oh yeah that might work too

[tribal meadow]

hmm, it didn't crash but no effect change

[grand temple]

what's coming in from above?

what particle system are you setting

[light bobcat]

Not really lol sorry
a lot of things have changed since. I should probably take it down at some point

[tribal meadow]

I think this is a step closer at least, thanks for helping. Going to give it a break. Maybe something will come to me

[light bobcat]

damn

They really need to add a lot of built in QoL functions to udon

[wicked forum]

Is it possible to restrict who can pick up a pickup object?

[light bobcat]

you could check if the player who held it is someone specifically, and if not, execute the drop function

unless https://docs.vrchat.com/docs/vrc_pickup is outdated

oh sendrpc is deprecated

[valid oar]

Yeah, there are a few ways but if you want to disable all pickups for people not whitelisted, you could check the name and if it isn't in the array of whitelisted names, set EnablePickups to false https://docs.vrchat.com/docs/players

You could also have the collider off by default and then have a hidden button to turn it on if you wanted to do it for specific objects and not worry about a whitelist, lots of different ways depending on how complicated you're willing to make the program and what you want it to do.

[wicked forum]

can I disable the collider for all the other users or will it try to sync that?

I can't disable all pickups since each object will have its own owner

[valid oar]

You can have a whitelist that turns colliders on that are disabled by default for people on the whitelist or one that turns off colliders that are enabled by default for everyone not on the whitelist, those are both options.

[arctic scarab]

okay how i use requestserialization

i have script with synced variables that crashes but after i rejoin it works

so the script runs before variables sync up

[lament valve]

There are rare chances when this will teleport everyone in the instance. Is there a way around that?

[arctic scarab]

maybe add bool if player already got teleported

[grand temple]

if you're properly checking local player then there is nothing about that that would cause all players to be teleported, it should be safe.

Unless you have some other logic that is actually moving this collider to touch all players or something, are you sure that's not happening?

[grand temple]

wait no I totally missed it lol, yeah of course that's going to teleport them all because all you're doing is checking if the localplayer is local, that's always going to be true. You need to check if the player given by onplayertriggerenter is local

[lament valve]

Oh I'm silly

Thanks!

[arctic scarab]

i have two serializations and none fix issue

synced variable is always empty

[valid oar]

This channel is for Udon programming questions but I would look here https://help.vrchat.com/hc/en-us/articles/360062658553-I-want-to-report-someone

[hollow folio]

I'll ask this here before trying it in case someone has already made it in some way and it'll save me a lot of effort. But (using graph) is there any simple way to have say, an array of 10 objects. Each time there's an interaction, one of those objects is picked and removed. Each time it's interacted with, this process will repeat with one of the remaining objects being picked and then removed. Finally when the last one is picked and removed, the array resets back to the original set so that the process can be repeated?

[indigo finch]

sounds like a classic object pool. well, if you want it to be synced anyways. just need a check to see if the pool is empty before resetting everything

[hollow folio]

It wouldn't be actual objects, but references to components. Is an object pool still usable in that way?

[indigo finch]

not really, it more of a way of spawning in objects without using instantiate. well, at least I wouldn't recommend using it. as for what your after, it's been done a number of different ways, but I would have to know what exactly your after to give an actual example.

[wind atlas]

Your last sentence makes me think you don't need an object pool. Isn't that just an array where you go back to 0 once you reach the last item?

But yeah, knowing what your goal is might be helpful.

[hollow folio]

Yes, but I want to pick from the array randomly, not incrementally, which increases the complexity a lot as I can't just use a counter.

[indigo finch]

actually, now that you say that, they could totally just randomise the array and cycle through it, and then randomise it again when returning to 0

[hollow folio]

That'd work. I didn't realise I could just randomise the array.

So I could just use a counter after randomising it.

[wind atlas]

It really depends on what you are doing. If you are fine with duplicate items, then you can just do Utilities.Shuffle -> get the item each time.

[indigo finch]

don't believe there is a node for it, but a simple shuffle in coding would be:
int n = list.Count; while (n > 1) { n--; int k = rng.Next(n + 1); T value = list[k]; list[k] = list[n]; list[n] = value; }

would have to convert that...

[wind atlas]

I think that's pretty much what Utilities.Shuffle does, but not sure if it's just in U# or also in graph

[indigo finch]

perhaps I'm just referencing old code...

[indigo finch]

seems like it's a thing. should remember that one..

[wind atlas]

That's good. This is literally the source code by the way:

Same algorithm

[indigo finch]

ah, neat. thanks for looking that up ^^

[hollow folio]

Ace, so I can just shuffle and increment through the array. Wonderful. Thanks guys 🙂

[hollow folio]

Hmmm, actually that creates a new issue, because then everyone will have a different "shuffled" version of the array where as I need everyone's "shuffled" array to be the same.

[indigo finch]

you could just sync the array. you will need to tell it to sync though, as I don't believe changing or moving variables inside an array tells everyone to resync

[hollow folio]

Oh, duh. Yeah, because I was thinking this was running on each person. Just run a requestserialization after shuffling it?

[indigo finch]

yea. will have to switch from continuous to manual sync too

[hollow folio]

Yeah, I'm on manual anyway

Hmm, how/when is the best way to do the randomisation? As I don't need it ransomised more than once per session. Just store a variable which is checked before doing the randomisation? Any better option?

So "Start" would end up with it getting randomised every time someone joined. I guess a "has been randomised" variable makes the most sense.

Look sufficient?

Ah, I need to set the owner first don't I.

[wind atlas]

What you want is let the first person who enters randomize the array and then propagate that to everyone else who joins. You seem to be on the right track, the only issue I see is that an AudioClip array might not be sync'able.

Instead, create an int array with the same values as indeces, and then shuffle and RequestSerialization it.

[hollow folio]

Ah...

[wind atlas]

At the start, you also might want to check if you are the owner of the object. Only sync if you are.

Also, the "randomDone" bool should be set to synced as well.

Although if we are testing for the owner, that bool might not even be necessary.

Since if someone joins an already existing world, there will always be an owner of that object and the array is initialized.

[hollow folio]

As different areas of the map are turned off until you go there, is it possible that someone in the session before you wouldn't necessarily be the owner?

[scarlet lake]

sorry for this random question but why is my object not interact-able and how do I make it be

[wind atlas]

From my experiences, whoever joins the instance first receives all the ownerships. But what you are saying is that some objects are turned off at the beginning? I'm actually not 100% confident if they receive ownership since they are not really activated. I think they do, but better test it.

[hollow folio]

Yeah, basically the map is in 12 sections, all but one are disabled at world start and they turn on/off as you move between them. Is there any downside to just switching ownership and setting the value?

[valid oar]

You need to add a pickup component (just add a component and search for pickup) and make sure there is a collider. Then you'll want to add an udon behaviour and drag in the ObjectSync script included in the SDK for the pickup to be synced.

[scarlet lake]

oh, I meant like that on Interact event in udon

how would I make it work

I don't know anything about this

[valid oar]

Do you have a script that works on interact? All you need is the script and a collider on the object.

[scarlet lake]

I have but in game I can't interact with the object
Like there's no floating text or outline

[wind atlas]

Hmm, I don't have any downsides right now. I'm just not sure what will happen if you use the very same state you want to sync in order to determine if you want to sync.

[valid oar]

Have you checked the bounds of your collider to make sure it's the right size and location?

[scarlet lake]

Yes
I followed a tutorial and did the exact same things

heres how the script looks like

[wind atlas]

The way I'd do it, is to separate your visuals and the data you have. Just randomize at the very beginning when someone joins. This way, you know that person always randomized that data already and everyone else will receive it. When you enable/disable areas on any client, the scripts inside just use the data you already synced as soon as they joined.

[valid oar]

The script itself won't effect whether you can interact with the collider, though the main issue with scripts like this is that the reference in the inspector for the button isn't set right. But if you can't interact with the button at all, you can't execute the script. Can you post the inspector of the button?

[hollow folio]

What's the easiest way to create an array the same size an existing array in the graph?

[scarlet lake]

oh God I was being stupid sorry

I fixed it

[wind atlas]

I don't really use graph so not sure. Surely there is some way to create a new array instance. If you can find that, just plug in the length of the current array.

[hollow folio]

I'd need to loop through the new array to set each value to 0-X to match the length of the existing array, for the purposes of the randomisation wouldn't I? Else it couldn't really act a proxy for the real array.

[wind atlas]

Yes.

[indigo finch]

I've got a bit of an advanced question, but I'm just checking some code, and I can't seem to find the reason as to why the first code doesn't work, but the second does. Anyone know the particular reason behind it?

[hollow folio]

Am I being dumb? This seems like it should work? (it should set blah[0] = 0, blah[1] = 1, etc)

It throws...

  An exception occurred during EXTERN to 'SystemInt32Array.__Set__SystemInt32_SystemInt32__SystemVoid'.
      Parameter Addresses: 0x0000002B, 0x0000002C, 0x0000002D
  
  Object reference not set to an instance of an object```

Oh wait, that loop isn't the issue at all, ignore me.

[indigo finch]

you need to set the size of the array first, and then use int[], set value to set each value

[hollow folio]

Ahh, I thought it would just grow as needed. I'll try that.

[indigo finch]

that only works with lists, and they are not currently supported with udon

[hollow folio]

I'm not used to C# hence my bad choices 😉

[grand temple]

That's because triggering a change in udonsharp is kinda split between two different things.

FieldChangeCallback is triggered by Udon itself. This is what allows it to respond to SetProgramVariable and receiving synced variables from other players.

But the thing is that when you set a variable directly, by just saying x = y then that bypasses the change check because it stays internal to the VM. There is no way for it to detect that there has been a change. In udon graph, there is a checkbox where you can say "trigger change" but literally all that does is change it to compile as setprogramvariable.

Instead, the intended way to do this in udonsharp is to use properties. Properties mean that you have a backing variable, let's say private int _clickCount that stores the value. Then you have a property, typically the same word but with different capitalization to differentiate, like public int ClickCount except instead of storing a variable, ClickCount has both a getter and a setter that works with and exposes _clickCount. Inside the setter of ClickCount is where you will detect changes.

If you use properties, then it will cover the raw method where you do x = y and then if you have a fieldchangecallback going from the backing variable to the property, it will cover SetProgramVariable and synced variables

oh yeah and btw, what this means is that you shouldn't ever do _clickCount = x because that bypasses the property. You should do ClickCount = x

[indigo finch]

thanks for the explanation, though tbh I'm a little lost as to it exactly. if you don't mind, mind adding some random context to the script so I can see it in use?

[grand temple]

I'm not quite sure what you're asking, is there something you're confused about?

so in your situation, you already have ChangeClickCount which is a property, and that will work, but I think you're misunderstanding what the property actually is. The property doesn't detect changes to the backing variable, it is supposed to be the interface to the backing variable. Which means you should never touch the backing variable directly. Which means that "ChangeClickCount" isn't an accurate thing to call it

[indigo finch]

you mentioned using properties, but I'm not familar with that term when it comes to coding (probably should be though...). Looking at your script you posted, the only difference i can tell is with the get part, but is that everything?

[grand temple]

bwah

[indigo finch]

so instead something like this?

[grand temple]

return clickcount and => clickcount is the same thing, just without using lambdas. Since this is the one weird unique case where udonsharp supports lambdas, I chose to write the example without them to avoid being confusing

but using => is totally valid and you do not need to change anything about it

[indigo finch]

I didn't really understand it, so I'm fine getting rid of it

[grand temple]

the only thing you need to change is that you need to set the property instead of the backing variable. Right now you are bypassing the property so it's not able to do it's job

[crimson thistle]

is it possible to swap the player's viewpoint into a camera in the world?

so for example i can make an intro sequence?

or something like that?

[grand temple]

Sounds like what would be appropriate is to just put them in a station

[crimson thistle]

yeah but i want the player to stay in place

[grand temple]

stations lock you in place

[crimson thistle]

ah

so its possible to swap my view to a camera?

[grand temple]

yes but that's not what you want

[crimson thistle]

i was just wondering if its possible

cuz i wanna like

make a button in my world

[grand temple]

you can override the view with a camera, but it has many problems. The audio listener doesn't follow, you get double the rendering cost, and it's based on your playspace so if they're turned around in their playspace they'll be facing away from where you want

[crimson thistle]

that makes me look thru a camera thats looking at a structure

from a distance

[arctic scarab]

why only host can run synced function and not othere players

[crimson thistle]

i dont need the audio listener of the camera, id like to still hear stuff around my actual body

down there

[crimson thistle]

so the view of the camera can move around or not?

cuz i dont want it to move at all

[grand temple]

well you can do that with other ways but that would be terrible in VR

[indigo finch]

only the owner of an object (default is the host) can change a synced variable, as the syncing is done master-slave type relationship. change the owner of the object if you want someone else to change it

[crimson thistle]

id love to attach a camera to the players back so i can get 3rd person

but also biggest motion sickness known to mankind

nah jk

[indigo finch]

does vowgans 3rd person prefab support vr? might be worth a look

[crimson thistle]

well either way how do i code up the thing that swaps my viewpoint to a camera?

or node up

[grand temple]

just enable a camera with depth 100 and no render texture

[crimson thistle]

and if its on depth 100 its gonna replace my eyes?

[grand temple]

well the depth 100 is just to prevent it from breaking stuff

enabling without a render texture is what really does it

[crimson thistle]

like this?

[arctic scarab]

object script is ran from or?

[grand temple]

yep

[crimson thistle]

and thats it?

[arctic scarab]

so the gui not the object i interact with

[grand temple]

cameras like this will be disabled by vrchat on start so you need to make something, either a script or animation, to re-enable both the component and the gameobject

[indigo finch]

where ever the variable (the actual information) is stored

[crimson thistle]

so if its on 100, it replaces my eyes? so if i wanna have my viewpoint as the camera i just set it to 100 for that moment?

[grand temple]

it's just a camera

doing camera things

that's it

[crimson thistle]

so itll work?

[grand temple]

try it

[crimson thistle]

aight ill see

ty tho

[indigo finch]

Thank you very much for your explanation! Took me a while understand what you were getting at, but I got it now ^^

[hollow folio]

@wind atlas @indigo finch Awesome, it works great. Thanks guys.

One last question on how VRC works. Do I need to "Set blah" again after changing the data, or will request serialization do that anyway? As currently that array has a "set blah" set after the constructor, but not after the data is written to it (but there is a serialization later).

[wind atlas]

I'm not sure if I understand the question. If you mean the syncing, once you call RequestSerialization, the array will be sent to everyone else and is available the same way you send it.

[hollow folio]

RequestSerialization pushes the changed variables out over the network if they're set to sync, right?

Yeah, cool.

So I'm just writing something to itself by adding another Set (blah) in there. I thought that was part of the network events but no, ok that makes sense, thanks.

[wind atlas]

Not sure if you have already, but the docs describes the whole process too: https://docs.vrchat.com/docs/udon-networking

[hollow folio]

Yeah I just started reading through them again after realising I've got some serious holes in what does what 😛

[dreamy talon]

not sure how to do this, but I want to isolate audio in one specific room. Like, when you walk in all the outside audio is cancelled and only the people in the room can hear eachother.

[arctic scarab]

when i rejoin world while game already started world seem to instantly crash out scripts

probably tries to sync up something

[thin kernel]

how do i make it so that a on player trigger enter only works locally

so far when any player trigger enters the collider i have it activates

ah i discovred that it can have a is local script

where would i plug that bool value into

would i use a is valid true to make it so only the local player can affect the local player api and not others?

[thin kernel]

dang

thx

[indigo finch]

np ^^

[hallow sable]

Any public scripts that would display a name from a button press interact and display it for all?

[indigo finch]

as in the player that hit the button?

[hallow sable]

so if a player touches a button, it takes that players name and displays it to all

[indigo finch]

so as in onPlayerTriggerEnter -->> display name?

[hallow sable]

uh no OnInteract to display name

and then that display name syncs so all players see who pushed it

[indigo finch]

if you don't mind the ownership being transferred:

[hallow sable]

what about doing it script wise?

[trail palm]

i want to do something where i dont even know if and how it is possible. i want to add a pickup object to my world that acts as a comic/ manga book. so its basically a cube that has some ui elements around it. i plan to host my own server and upload the comics/manga (mostly selfmade or CC) there under folders. so it would be www.domain.com/manganame/file0.jpg or something. i want to make a script that has a string for manga names and a string for the images. so the manga name string should be added to the corresponding part of the url and the same for the image string. meaning that the player should be able to select the manga and then it auto starts from image 0 all the way up to the last page when clicking a button. then ofc the script should also download said image and put it in the object material.

is that even possible?
if so, what would be a good start to make it?

[indigo finch]

unfortunately, any url modification, or getting information from a website that isn't strictly a video is against TOS, so I can't recommend it, and you won't hear about it here. That being said, there is a pretty advanced/ technical prefab out there to get data from avatar icons on avatar pedestals, but that would be pretty painful to setup; if it would work at all.
Have seen some create use of video streams though, so perhaps have a page every second of video, and have a script scrub through the video? that would be my best bet if I were to try

[trail palm]

hmm

the video idea doesnt sound that stupid

[hallow sable]

and that would sync it to others too?

[indigo finch]

whoops... forgot to add the udonsynced

[hallow sable]

udon doesn't sync text tho

[indigo finch]

late night coding... Ignore that last change lol

[hallow sable]

Won't I have to sync a string or no?

also uh

[indigo finch]

I'm making the player that hit the interact, the owner of the object. that makes them responsible for all synced variables, and is often done when making a script networked. I'm then getting everyone to run the function OnOwnershipTransferred that runs whenever the ownership changes. Also, since the owner is stored as a VRCPlayerApi, we can get their name from that

[indigo finch]

huh...

[hallow sable]

nvm fixed

[indigo finch]

cool ^^

[cedar iron]

Please help, this is breaking my mind. I dont know why this is happening. All I did was add a Graph Udon Behavoir to a pickup object.

for context

[hallow sable]

it's not working? unless it doesn't work in cyanemu?

[trail palm]

not too sure, but i dont think that the cyanemu instance has a name so it has nothing to display

[arctic scarab]

does vrchat have limitations to object position

[indigo finch]

Cyanemu's great for testing, but it should never be relied upon. Always build and test if something isn't working, to make sure it isn't a cyanemu problem (especially with cyanemu, as it's getting a little dated at this point)

[hallow sable]

ill try that bc normally it works but building and testing rn to see

[quartz meadow]

deosnt look like HumanBodyBone arrays are exposed in udon?

[quartz meadow]

The new built in VRC emulator is leagues better (it is essentially the new version of CyanEMU)

Its good for rough checking, but always check in VRC occaisonally just to be sure everything is good

[trail palm]

does anyone know how to use terrain layers in the udon graph? i cant find anything that works with them

[dense birch]

scene descrtiptor is empty

[valid oar]

Don't make your own descriptor, just drag in VRCWorld

[dense birch]

i did

with the add component button

nvm i fixed it

[trail palm]

is there any way i can manipulate these terrain layers with udon? i am making a rain system and want to bump up the smoothness value when its raining, but otherwise i want it to not change

[arctic scarab]

is gameobject toggling synced by default?

[coarse parrot]

It isn't

[arctic scarab]

somehow it does

[coarse parrot]

There probably is a script that get triggered on both side to toggle the object.

But game object activeness doesn't sync, unless managed by object pool or other scripts

[arctic scarab]

i have script for local toggling object on exact time on timer

and i see it getting toggled before it hits the time for me

so somebody else loads it faster on desynced time and i somehow see it

[wind atlas]

The methods for that are not exposed in udon.

[wind atlas]

Can you use animations on the terrain? That might work if you can.

[cedar iron]

I was using the USharp Video Player, and there's a script missing. Can someone help?

[coarse parrot]

Have you installed world sdk?

[cedar iron]

yes, this is 95% through the dev process. I am using the creatorcompanion, which i think uses packages instead of assets for the vrcsdk

[coarse parrot]

The script is VrcUrlInputField. It comes with world sdk though. Not sure what changed in CC version

[cedar iron]

thanks for the name, i'll search and reload the sdk to see if I missed something

[cedar iron]

How do you setup a button that if you press multiple times, it cycles through different positions of an object?

It may be a possibility with a counter, but i'm not really sure how to set that up

[scarlet lake]

How would I do this? (Image)
I'm completely new in Udon and couldn't find anything online

And please ping or DM me for replies

[coarse parrot]

I don't think you can change that via udon

[scarlet lake]

So it's not possible to create a "customizable" mirror like this?

I wanna avoid creating multiple mirrors and enabling/disabling them

[scarlet lake]

Okay, and how would I make the udon script notice a button click at all?
Do I just add a udonbehaviour into the button, and add a Interact event ?

[coarse parrot]

Yes. Add Interact node event

[scarlet lake]

Okay thank u

[midnight beacon]

Are there any advancements on getting the camera object VRC creates? I need to set the main camera to not cull something but VRC doesn't respect the culling mask settings when creating it's own camera for the local player. Anyone know of any workarounds?

[trail palm]

is it objects that should not cull for everybody ? wouldnt it work to simply slap the editor tag on them?

[midnight beacon]

They need to render in a separate camera to the main camera

Using EditorOnly would cause them to disappear from both

[trail palm]

does anyone have an idea how to make a timer in u#? i want that after about one hour, a gameobject is activated for 5 minutes and then deactivates itself again and waits till the next hour passes to activate again etc. how would i approach that

[midnight beacon]

I dont have the exact APIs in my brain but the way ive used it before is the Time property in Unity, specifically one where you can get the UNIX time. When the world starts record this time, the measure the difference between this time and the time on the update

[slim hound]

Assuming you don't want it tied to system time you could just use SendCustomEventDelayedSeconds

[slim hound]

If you need to render something only on a specific camera you can add an udon behavior with this to the camera object

[midnight beacon]

Interesting, thanks for the tip!

[trail palm]

but then i dont get how its supposed to loop

[trail palm]

that does make sense, but i still dont quite get how to translate this into code

[slim hound]

        SendCustomEventDelayedSeconds("_OneHour", 3600F);
    }

    public void _OneHour() {
        SendCustomEventDelayedSeconds("_FiveMinutes", 300F);
        gameObject.SetActive(true);
    }

    public void _FiveMinutes() {
        SendCustomEventDelayedSeconds("_OneHour", 3600F);
        gameObject.SetActive(false);
    }```

[cedar iron]

Can someone please help me with this? I was trying to build a system where if a button is pressed repeatedly, the USharp Video Player's screen & audio would move to predetermined spots (pos0, pos1, pos2) in the world.

Here's what should happen:

• Player presses the cycle button

• Counter increments to 1

• Video & Audio move to pos1 from pos0.

• Player presses the cycle button

• Counter increments to 2

• Video & Audio move to pos2 from pos1.

• Player presses the cycle button

• Counter increments to 3

• System reads Counter as 3, resets it to 0.

• Video & Audio move to pos0 from pos2.

Issue is, that's not what happens ingame.

Here's what happens at the moment:

• Player presses the cycle button

• Counter increments to 1

• Video player does not move

• Audio moves to pos2

• Player presses the cycle button

• Counter increments to... 0?

• Video player still doesnt move

• Audio moves to pos1??

I've tested the increment using a visual integer on a canvas text that I also use to save the integer between cycles.

Can someone please read over my code to figure out why this is happening?

Better quality graph

[trail palm]

ok, but i also have a toggle that if its on, the game object is on the entire time, only when its off it goes through that cycle. so i have code like this. would this work?

[slim hound]

Not sure I understand, if its on it stays on forever?

[trail palm]

yes. its a rain system. if a player click the local rain ui toggle, it stays on forever, however if it isnt clicked, it should cycle through the loop if that makes sense

[slim hound]

Ah right

[trail palm]

but my code doesnt work

[slim hound]

Yeah you shouldn't have an update event

[slim hound]

This is all you would need

[hollow folio]

Is it possible to have an onChange node fire if a value is changed to the same value it was before?

I was using an onChange node to fire when an int was changed, but I realised in some scenarios that the list only contains one item, then when it's fired, it just gets set to the same value, which in turn doesn't trigger the onChange so I'm not sure of a good way to handle that.

[trail palm]

i will try your method, what i found in the mean time probably isnt as optimized lmao

[trail palm]

when i use your method, i wont need to have the marked part anymore right? since the script will now activate it and not the toggle

[slim hound]

No you would still need that

[trail palm]

something doesnt quite work. if i set the toggle to on, the rain will kick in imediately, but after a while it will disappear

to test it, i have made the _OneHour event 50 seconds long and the 5 minutes event 10 seconds long. now if i click the toggle, the rain comes down for 50 seconds, but as soon as the next event comes in, it disappears again and reverts back to normal even tho the toggle is still on

[slim hound]

Are you still using an update event or did you change to using my example completely?

[trail palm]

i am using OnDisable now

[slim hound]

Okay so TIL you can't use OnDisable to SetActive the same GameObject

So this instead

[trail palm]

ill try

[scarlet lake]

Hi, can i set position of an gameobject trough udon?

[valid oar]

Yeah, I think the node is just called set position

Or location, one of those

[scarlet lake]

I searched for position and nothing appeared

I'll try with location when I get back

[slim hound]

You would search for transform and then under transform search for position you should find it then

[scarlet lake]

Okay thanks

Ill be honest, I don't entirely know what went wrong, but one thing I would definitely point out is that you shouldn't share nodes with other events, as in this case I believe the temp int is being discarded after it tells the other event to play, so these branch nodes won't work (or may be buggy). I would change that before I would look into the specifics with your video player models.

This is how it would look if separated out, though I did change the int 'resetInt' variable at the bottom to a int,const, as it always should set it to 0. So, here's a similar script using your method, that I've confirmed does work with regular objects; though I would need to install the asset to check for the video player:

that being said, your using a convert on the text string from the uiText, but that is not 100% reliable, and is generally really bad practice. I would create a private int, that keeps track of what the text number should be (also would make it much easier to sync with other players if you wanted that). I also removed the extra custom events 'pos1' and 'pos2', because they wouldn't really do anything, and you would be better off calling 'pos0'

That being said, another problem with this, is that your using 3 different transforms for the positions. This is fine and all, but what if you decided that you actually wanted more or less? You would have to edit the code again, and it's already getting pretty laggy with just these 3 positions. So, in this case, an array (essentially a defined list) would be much more suitable. It would also significantly reduce the amount of duplicate nodes, and allow for you to add or remove positions as you see fit. (do note I made a slight change to the int counter part):

And lastly, you had the events 'pos1' and 'pos2', and I assume they were meant to be an override to the increment counter, as a way of having a button that tells it to move to that particular position. To do so (without having a small script on each button), here's a small little addition, that should allow for that to happen. It isn't scalable though, so you would have to add a new event for each button/ position:

and if you wanted to instead make it scalable you would add this small script to each button instead of those extra events, and get the button to call this custom event 'OnButtonClick'

Hope you don't mind me heavily critiquing your code, especially as some of what I said wasn't 100% relatable, but sometimes when something only 'sometimes' works, the problem could be a lot greater, and therefore the code should never have worked in the first place. This also kinda caught my interest, as it was a weird and wonderful way of doing it, and I was interested to see if it worked ^^

[indigo finch]

Don't believe so. Normally I would do a check to see if they are the same, and fire a networked event if they are. You can just plug the custom event into the same arrow slot as your onChange event. If you are doing this, don't use the variables on the onChange event, as they won't be accessible from the custom event

[hollow folio]

Yeah, that's what I ended up doing. There's no worry about the var changing fast enough if it's not changing in the first place.

[light bobcat]

how can i make the screen fade to black in udonsharp?

[valid oar]

I don't think you can do that directly with Udon, you'd need to either use post-processing (which would only work on PC), a screen space shader (not sure on how that might work), or you'd need you put something in front of their face that would fade to black. You can also use a technique where you scale all of the objects up and use a black material where you animate the alpha but that requires a bunch of work with duplicating models and animating materials.

You can also use a realtime light but then the angry mob will come and try to capture you and take you to optimization jail.

[lament valve]

I would just animate a screen space shader like VRC Cancerspace

[desert apex]

Does anyone know why my avatar goes into pc mode every other avatar I use when I'm on quest?

[valid oar]

I don't know what PC mode is it this context. It displays the PC version? Is the PC version different from the Quest version?

[desert apex]

No just I can't move my arms and I walk like a PC user.

[indigo finch]

this is better asked in #avatar-help or #user-support-old

[desert apex]

ok

[broken gale]

Hey. I'm trying to have a plane always face the player, giving the illusion of a sprite. What is the best way to do this? I've been tinkering with it all day to no avail.

[valid oar]

I don't know if it's the best method but you can use a particle system. You just create a standard material with your texture on it, create a particle system, apply the material in the renderer tab of the particle system, set "rate over time" to 1 in emission, and then at the top set "start speed" to 0 and "start lifetime" to something ridiculously high like 999999.

I'm sure there are other methods but I think a particle system with 1 particle should be a fairly minimal performance hit.

[formal ledge]

I have a world with a moving platform. I have VRC Object Sync on the platform, but it is not synced when my friends join
Am I missing something?
i have the udon sharp script set to continuously sync

[broken gale]

I just tried it, and while cool it's a little unruly. Was hoping to do this in Udon.

[valid oar]

I don't think billboards are usually created with Udon, you'd need to get the location relative to the object and the rotation of the head every frame which seems inefficient though probably possible. You might want to look into the billboard renderer component. https://docs.unity3d.com/Manual/class-BillboardRenderer.html

how flexible is game-making within VRChat? what are the limitations? and what are some of the worlds that best represent VRChat game making to its fullest potential? thanks in advance

[valid oar]

With enough time and cleverness, I don't think there is much you can't do in VRChat aside from being able to send and retrieve data and maintain persistence between sessions, though I think even that is doable to some degree. You're probably not going to make a functional MMO in a VRChat world but aside from that, you could probably replicate most genres to some degree. Many of the most impressive games inside of VRChat are PC-only due to world size and performance constraints but if you have access to a PC that can handle it, I would check out Noir: Nocturne and The Devouring. For Quest-friendly worlds, Super VR Ball is a lot of fun.

[rancid parcel]

that is exactly the answer I was looking for. thank you

[queen panther]

You're going to be looking at mainly minigame style worlds. Some larger adventures are possible, but "saving" any progress requires something like giving players codes after they complete a section to enter when they rejoin the world. The code would then take them to the last "save" spot. Persistence for vrchat is planned to be added in the future, but it's unknown when.

[valid oar]

Yeah, the bigger experiences like The Devouring are generally a multi-hour time investment because you have to get through them in one session whereas Noir: Nocturne using a code system.

[rancid parcel]

so to my understanding the only limitation is saving progress on the experience (meaning there is no player specific database) which means most games should be designed as an "arcade" type of experience. but outside of that all functionalities are possible as long as its not too out of this world? (no pun intended)

to clarify, im more or less talking about pc side of things

[valid oar]

Unless it's a video, you generally can't pull anything from a source outside of what's in your scene, aside from that Udon does lack certain functions available in native C# and VRChat is still using Unity 2019 so you won't have direct access to anything introduced since then (yet) but the people that really know what they're doing tend to find workarounds for most limitations. That's not to say it will be easy if you're trying to do something that has never been done before and it's kind of hard to answer the hypothetical of what might be impossible without omnipotence but sufficed to say, you can do a lot.

[broken gale]

At the risk of maybe asking a stupid question, how is that different from billboarding scripts?

[hallow sable]

so sadly it didn't work no matter how I messed around with it

[lament valve]

I have a toggle in my world that is supposed to toggle things locally but ends up toggling for everyone locally. How can I change that?

[obsidian hinge]

so this is the channel where I ask questions about vrchat?

[valid oar]

Seems like it would allow Unity to do the calculations for you rather than you having to do that yourself. How it works or whether it would be more efficient, I don't know, it just seems to be how Unity handles billboards for things like Speedtree. I also found some billboard shaders but none that seem to be compatible with Unity 2019.

[valid oar]

If they're about programming in Udon. If they're general VRChat questions, maybe try #user-support-old ?

[obsidian hinge]

alr

[coarse fern]

Hello, what I do in this cases is just go to the settings and you will see a person standings with a circle on them I think, click it

And that’s it

[scarlet lake]

Hi does anyone know where I can ask for avatar commissions?

hello?

[valid oar]

You're not always going to get a response right away. Check #community-servers-old , if you scroll up you can find a link to the VRC Traders Discord server.

[scarlet lake]

ok

[scarlet lake]

it says invalid invite

[valid oar]

Google it

[scarlet lake]

?

[valid oar]

Google the name of the Discord server

[scarlet lake]

oh

[vapid badger]

Hello, I was told I could ask this question here also: #world-development message

[shy osprey]

how do i transform a single object in an array? the game object output from the Get node doesnt connect to the transform set position node

are these the right nodes? or do i have to use a different transform node

[tropic canyon]

you need to get the object from the array

it's a Transform[] and a Transform node and those can't connect

[shy osprey]

does the get node not do that?

[tropic canyon]

ooh

you got a GameObject[]

There should a GameObject.Transform node thing

[shy osprey]

this one?

[tropic canyon]

yes

[shy osprey]

kk, that seemed to work

thanks!

[arctic scarab]

how i make dictionary

[tropic canyon]

Good luck. It's not a supported type

[vapid badger]

Are spatial audio sources generally much quieter than 2d ones? There's a "gain" parameter on VRC Spatial Audio Source, but it doesn't do much. (World building, not avatar)

[vagrant pendant]

Is OSC support going to exist in the future?

[ebon dragon]

try checking what it sounds like when you put your head exactly where the audio emitter is; the default falloff curve is quite steep

[hollow folio]

I'm not at a pc right now so sorry for the vagueness but can you enable or disable objects globally in a scene by tag?

[wind atlas]

I don't think that that method is available, but might be wrong.

At least this one isn't:

[hollow folio]

Damn. What is the easiest way to mass disable colliders and such? The colliders are part of a prefab (eg dozens of copies) and there's nearly 100 so I'd rather not wire them all up manually...

Also it's weird that that isn't wired up...
