Thank you~

[somber hawk]

What is VRCPlayerAPI.isModerator? It doesn't seem to be documented here https://docs.vrchat.com/docs/players

[floral dove]

it's not documented because it's not usable in Udon

[void ridge]

from: https://docs.vrchat.com/docs/player-forces#getgravitystrength--setgravitystrength

GetGravityStrength / SetGravityStrength

float, working range around 0-10
Multiplier for the Gravity force of the world (set to Earth's default). Don't change Unity's Physics.Gravity in your project, get and set it here instead. Default is 1.
Why the "don't" here? For now Physics.Gravity seems to work fine, and it's the easy way to change gravity for all players and all rigidbodies

Momo?

[floral dove]

does it work in the client or just in the editor? It would affect all other worlds if you modify the Physics.Gravity value directly. Not sure if we allow it and just reset it when you change worlds, but in general we discourage modification of properties that could persist when you visit other worlds.

[void ridge]

It works in client. In the case of the world I made, I modified the project setting rather than using an Udon program

So that definitely makes sense if the setting is in the realm of stuff that could screw with people's games outside of your world. Does this mean changing this value is an 'exploit' of sorts that might stop functioning in a future update?

[floral dove]

It's possible.

[serene moat]

setting the project gravity has been one of the things that has worked for a long time even in SDK2

pretty sure VRC explicitly applies it on world load

[void ridge]

It seems likely that they do, but the question is whether they need to do it that way or need not. If something in the future makes it desirable not to do it that way, then this becomes a landmine

[paper plinth]

That would be hilarious if you could somehow get the player mods to persist...would be a super fun time until you got b&

[void ridge]

And that's why they pack so many big brains into closed and open beta 😉

[serene moat]

It's one of those things where it'd make a bunch of worlds act differently and they have support for it

¯_(ツ)_/¯

they could remove it, but it'd break worlds for no particular reason

[eager olive]

Today I've had to use Physics.gravity to circumvent an issue with VRChat's player gravity: https://feedback.vrchat.com/vrchat-udon-closed-alpha-bugs/p/setgravitystrength0-does-not-actually-disable-gravity
I think it could be removed if SetGravityStrength(0) worked properly, and if gravity was applied in FixedUpdate().

[fiery yoke]

Try doing SetGravityStrength(Mathf.Epsilon)... no idea if that works or not lel

[eager olive]

Oh goodness! You should mention that in the canny

[fiery yoke]

Does it work?

[eager olive]

Setting it to 0 set it to 0.1 for me instead, would be funny if Epsilon actually worked

[fiery yoke]

Igbar technically said exactly that

just in a less "formal" way

Epsilon is in mathematical theory a number that is infinitely close to but not zero
Since computers like to be discrete, here its just the smallest number representable

[eager olive]

trying it rn. though that still leaves the update vs fixedupdate issue

thank you for the suggestion!

yep, that seems to have done the trick

-giverep @fiery yoke

😄

[paper plinth]

good chat folks
way to keep it relevant
now I can make quicksand

couldn't figure out how to get that gravity down

[sick thunder]

I'm sure this has been asked before, but is there any definitive limit on the number of udon synced variables?

Or is it just however much Photon can handle?

[harsh peak]

anyone knows here dope tutorials for udon?

Thanks for the links! Appreciate it. I actually did the first one already

[quick basin]

really struggling to get a audio source working

to toggle

[broken bear]

is there a player audio occlusion method for udon for world objects? For example, reduce or even negate player audio when they move behind a wall. I know guribo's audio system can do it for occlusion between players or facing/distance, but not objects. Goal is to have areas that work like camera occlusion to prevent audio traveling outside boundaries

[pale heath]

cansomeone help me my mic is working and everything in the setting and everything is working but stell cant speek

[dapper lion]

@broken bear jetdog has a prefab where it has zones you can use but i havent seen anything public like a material barrier or just a basical audio barrier yet. but it is technically possible

[normal zenith]

Hello, I am wanting to have the skybox slowly rotate in the world and I used this video as a guide script wise to allow for that but when attempting to build and run the world with the script running on a game object I am crashing immediately but placing it onto a camera (attempted with the main and a secondary) does not cause it to execute. Would anyone have information on how to fix this? https://youtu.be/cqGq__JjhMM

[floral dove]

You can't use Unity Scripts in VRChat - you'll need to learn Udon to make things happen.

?whatisudon

[hidden marten]

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

[silent gazelle]

Just quick question, it possible to check if player holding item and the type/name of the item?
Item from the world

[twilit hawk]

You can access the current holder of a pickup with VRC_Pickup.current_player (iirc), and you can access pickups in the hand of a player with VRCPlayerAPI.get_pickup_in_hand (names might be slightly different, but that's the gist)

From there you can access gameobjects and udonbehaviour components and variables, etc.

[silent gazelle]

Gotcha, thank you very much!

[twilit hawk]

No problem, good luck!

[silent gazelle]

If player pick ups an object, he turn to IsOwner of this object?

[twilit hawk]

Sure, they do, but ownership is inconsistent sometimes (supposed to improve in upcoming versions of udon), and you're better off using the current_player from the pickup component

But yeah, whoever picks up a gameobject with a pickup component automatically becomes the owner, after several networking ticks

[shut patrol]

Is it possible to find out the radius and height of player capsule?

[paper plinth]

I have a rotating skybox shader I got off the asset store, you might try something like that

[bold marlin]

Can anyone tell me how i can damage the player in udonsharp? or have a small example?

[quasi rivet]

wasabi

[dim horizon]

RED_SIM has a great sky shader specifically for VRC if you're willing to sub to him on patreon. You can change the time if day by rotating the directional light in your scene or you can animate it. https://www.patreon.com/red_sim

[normal zenith]

@dim horizon @paper plinth thanks for the info, appreciate it

[balmy plaza]

Does the game work without a VR Headset and if it does, how well does it work?

[vast locust]

Yes on both questions.
It works without VR.
It works just as well on Keyboard^Mouse as it does in VR.

VRChat is not large, Super small download. Just download and test

[balmy plaza]

I am enjoying it rn

[trail verge]

Would anyone have example of how to build a udon graph for UdonSyncPlayer to have a time position slider (to be able to fast forward into a video to some point) ??

[vast locust]

Check out @cunning mist's Youtube channel. He has a tutorial video on it.

[balmy plaza]

How do I switch avatars without going home?

[vast locust]

Not #udon-general , Just click the avatar button

[scarlet lake]

hey does anyone know a way i can change my worlds fog to black at night?
i dont need any fancy slow move to black just a instant click would be fine, i mean thats how the shops cycle works

ive looked it up online but all i have sound is scripts and stuff that i have no idea how the hell to use

[vast locust]

Not sure how you have it setup the fog but can you just make a duplicate of it and have a button switch between two different "Fogs" ? One is darker, One is lighter

[scarlet lake]

its not like particles

its using unity's built in fog render

its in the lighting tab

but no idea how to play with it

the fog looks fine in the day

but at night.. less so

[cunning mist]

Is this exposed?
https://docs.unity3d.com/ScriptReference/RenderSettings-fogColor.html

[scarlet lake]

it is close to what i want @cunning mist but i have no idea how to do those scripts, dont know the programming language, and ontop of that i cannot use a hex code to get specific colors

[cunning mist]

All scripting words are the same as their nodes. Just search in Udon for RenderSettings and see if anything comes up.

[scarlet lake]

ill have a look now

tbh i might just have to live with the wierd fog

also this works surprisingly well

this also makes me feel REALLY small

like wow

[trail verge]

I did.. he did not make a time slider in his tutorial.. (I went through the 3 hour one even x.x)

[cunning mist]

Make a slider that goes between 0 and 1. Then when you start playing a video, set the max value of the slider to be the length of that video. In update, while it's playing, set the value of the slider to be the current video time. On the slider, add an Event Trigger component. OnPointerClickDown, call an event that pauses the video. OnPointerClickUp, call an event that sets the time of the video to the current value of the slider, then resumes the video.

[trail verge]

Thanks! goes to poke around

[void ridge]

@cunning mist did you ever figure out any workaround for this issue?
https://feedback.vrchat.com/vrchat-udon-closed-alpha-bugs/p/1048-toggling-disablestationexit-does-not-affect-player-currently-in-station

[cunning mist]

nnnnope

[void ridge]

I'm setting a delay timer that locks exiting for 3 seconds, and it never unlocks

womp womp

[cunning mist]

There's a chance you can try turning the chair's gameobject off, but I haven't actually experimented with it.

[fiery yoke]

Last time I experiemented with Stations ... toggling them (while sitting in them) leads to a lot of unexpected behaviour 😅

[void ridge]

yeah this is getting ooky. Disabling the GameObj might be an OK idea

[trail verge]

I'm missing something here 😛

[verbal socket]

i kinda want to create an NPC in my world

is that possible ?

if not can some one send me a tutorial for toggling in between 2 things ?

so if A is on and you toggle it B will turn A off

[floral dove]

It is! But it's a big project if you're just getting started. If you need a tutorial in order to toggle between two objects, I think you're best path forward is to start with the basics.
https://docs.vrchat.com/docs/getting-started-with-udon
https://www.youtube.com/playlist?list=PLe9XHNvXcouQjg5GULWGLj1tMzeythnQi

[verbal socket]

like ican toggle things on / off

i thought i could make panels with text

and turn it into an menu maybe

xD

so i would fake it being a NPC o3o

its mostly if people want to ask me stuf

i can put the FAQ on the model in my world

and people can ask there

[gusty swallow]

Does uh.. did anyone have a prefab for teleporter doors that I could use? There's only one recent tutorial that covers it and it didn't seem to work for me.

https://youtu.be/vPPpFokmS-Y

This is such a simple thing I could get done in SDK 2.0, I don't know why I have to struggle this much for udon

If anyone has a prefab they could throw my way I'd appreciate it

[dapper lion]

@gusty swallow i has a walk in teleport if you want that

its not a button

[gusty swallow]

Honestly anything will work lmao

Thank you so much

[dapper lion]

cool

[verbal socket]

i would love that as well

is it then if you hit a collider your automatically teleported then ?

[dapper lion]

mind opening your dm?

yes sir or maam

[verbal socket]

just yeet the code in DM

or the asset pack

[dapper lion]

i cant dm you for some reason

[verbal socket]

we had a convo

just spoke twice

o3o

[glossy sky]

Hello hello. Is there a way to ragdoll/kill players like in SDK2? Looked around and saw that SDK3 and the combat system for it was highly discouraged so I was wondering if there was a work-around for that.

[fiery yoke]

https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback/p/ability-to-ragdoll-the-player-via-api

No there is not.

The only way is to use the "outdated" CombatSystem.

[unborn hornet]

A general question to put things in perspective: How long as SDK2 existed and how long has SDK3/Udon existed? (As mainline releases that is)

[glossy sky]

Ahhhh, alright. Thank you very much for the information! I suppose I'll make do with it for the time being until another method is made available.

[narrow ether]

I'm wanting to create a Club world with Udon but I've only worked with SDK2, does anyone have any sources for tutorials or prefabs I could use for it? (Light effects, DJ booth, audio, etc)

[lilac hatch]

So hm, I have a question / an issue i'd like to talk about.

I made a world with a videoplayer for quests users using u# (in case it matter, the one shared by Merlin), the videos seem to play fine and stuff but everytime, the video just stop in the middle of the file.
I guess it's because quests don't have a lot of cache space / don't allow files over X in files, but is there a way to tweak that on quest ? (The video files are kinda big and I don't wish to re-encode all of em to 480p or smh)
Asking them to restart the instance 2 times to clean the cache is a bit MonkaS aswell :(

[floral dove]

do you get any errors when this happens? You'll need to use Android Debug tools to pull logs, not sure what we log on Quest, I know we turn most logging off for performance.

[lilac hatch]

I sadly don't have a quest myself to try it ! Is there any tutorial to pull up logs anywhere I could ask someone to do ? :o

[floral dove]

there's some information here: https://docs.unity3d.com/Manual/LogFiles.html

[lilac hatch]

Seem to honestly be a pain 👀

[floral dove]

it is - debugging Quest is not easy

[lilac hatch]

I'll just let the people re-make instance for the time being, but yeah, it happen after the file hit a certain size I think since clearing the cache just seem to do the trick

and 480p seem to play all the way trough it

[trail hazel]

is there a vector version of the udon logo available?

[paper plinth]

There's a prefabs list if you search the discord.

[trail hazel]

the press kit for vrchat, ironically, mentions in the usage guidelines to 'avoid artifacts' but issues no vector format for any of the logos, nevermind the udon one

there's a relatively low quality raster version in the SDK that gets used for UI but if a higher quality version exists i'd want to use it because the raster version will look awful on docs pages on mobile where hidpi logos really show

[floral dove]

we don't provide one generally, where are you looking to include it? The Udon logos in the SDK are 1024 pixels wide, what size are you looking to make it?

[trail hazel]

i'm mostly looking to include it in docs pages and readme files, etc, potentially as part of a header. the udon logos in the SDK have whitespace around them so they end up being maybe 250px? high, which is fine for desktop displays, but tends to look worse on mobile and print formats (such as PDF builds of doc pages)

[floral dove]

what PDF docs are you making?

[trail hazel]

a higher quality version at all would be nice, but ultimately vector will always render better than raster across screens (because it can ensure sharpness), and presuming one exists it'd be nice to use it

i'm making effectively "udon libraries" that utilize U#. the docs are interface docs that describe signatures, API reference, guarantees etc of scripts within them

[floral dove]

sounds cool! I'll see if we have a vector version we can share.

[trail hazel]

also as an aside: the time it takes to download and render a vector version on mobile is usually faster than it would take to download an equivalent quality raster image, so can help reduce FOUC there as well

[keen oyster]

Is there any way to get a bone transform for parenting purposes? i.e. say i'd like to parent an object's position to someone's arm

i'm guessing that the answer is a no so that you can't modify the transform from udon, which is a shame, and i'd just have to make do with setting the object's position/rotation periodically, but i figured i'd ask instead of making an assumption

[floral dove]

you can't directly parent something to the bone, you need to update the item's position to match

[fiery yoke]

If you need several objects, then make a proxy object that you update and parent to that

[keen oyster]

nods thanks for the confirmation

[floral dove]

@trail hazel here you go!

[paper plinth]

hey I forgot to ask something
the other day I was in a world that was a complete disaster
it was very fun but without a doubt breaks rules because it vibrates the player and makes all the game controls unuable
so chernobyl guy if you're in here I sent you a friend request
that's about all I can do besides this
If you're out there, let's collab...

[fiery yoke]

@ivory thorn You want the highest sample rate you can get, for the best quality, so you can divide it later. Also you can scale cubes with a Vertex shader, instead of actually setting their scale. Has some problems, but it generally works fine. Depends on what you want.

[ivory thorn]

imo it looks ok with 64 sample and then I have 6 ranges of frequencies which output nice -0-1 float to use

[fiery yoke]

Well yeah it solely depends on what style/look youre going for

[ivory thorn]

e.g. I can take only low freq if I want mat to blink only on base or something

What I am not sure is the perf. impact of like 256 sample

[fiery yoke]

For Unity getting the 1024 samples is no problem at all

You just cant do anything with them in Udon because Udon is way too slow for processing that

Thats why my world relies purely on shaders

[ivory thorn]

Well then I will stick with 64 for udon 😄

If you have know any useful shaders I could buy for visualization let me know, shaders and black magic for me 😛

[fiery yoke]

Same.

[waxen breach]

So right now im having a problem where i updated to the latest udon and version of vrchat but when i build and test its not updated and is using the last version of vrchat. i need to test a udon using the new is valid but it wont work since it keeps using the last version. Do i need to reinstall udon or vrchat to fix?

[gaunt rover]

Does anyone know if there's a way to make it so that if you click a button, it'll change the skybox for everyone in the world and not be local only?

[unborn hornet]

You'd need to use SendCustomNetworkEvent -> [NetworkEventTarget] All, "MyEvent"in some capacity

[gaunt rover]

Ah ok. ty, ty! I'll try that, although I'm not sure how to use that node yet. XD

[floral dove]

make sure your VRChat SDK Control Panel Settings point to your install of VRChat: https://docs.vrchat.com/docs/using-build-test#setting-up-your-settings

[gaunt rover]

Thank you so much!! It worked!! 😄 😄 😄

[narrow ether]

i feel really stupid but I can't find it 😅 do you know what channel?

[frank lily]

anybody know how to make it so people can slide up a whole wall? i've seen in some worlds where they probably put colliders in a very specific way so when you touch the wall you kinda get shot up to the top of the wall

like for a ladder or something

that udon yeet world had it

[paper plinth]

I will find the link

[unborn hornet]

[idle brook]

Does anyone know when the Udon will have midi?

[cunning mist]

[dapper lion]

thought it did?

[gray bane]

hello

[waxen breach]

it is pointed to the install of vrchat. Its able to build and test and even upload. The problem is it just starts vrchat in a older version (the last version) (build 1040 i think). I can start vrchat fine regularly and when ingame it says the latest version. Maybe i just need to reinstall vrchat. if i cant get it to use the newer version ill try reinstalling udon/vrchat.

[somber hawk]

Is it normal to have Unity hang for 10-20s pretty regularly between tabbing over to edit some U#? Any tips for how to improve this? 😄

[twilit hawk]

It happens every time I save the U# source. I think it's just compilation triggering because a file is modified.
You can disable this in the Edit > Project Settings > Udon Sharp tab.
Turn off "Auto Compile On Modify", and "Compile On Focus" and it should stop hanging until you manually compile everything

Speaking of, I should probably turn those off too - considering I compulsively recompile anyway 🤷‍♂️

[trail hazel]

it's because the editor has to rebuild

[somber hawk]

Hm I only have compile on modify on, but I don't always see the "n scripts compiled" log when it hangs, I guess it could be checking if they are modified being slow? But I'd expect that to be pretty quick.

I'll definitely test turning it off to verify if it's actually u# or not

[lilac hatch]

well i didn't expect much when checking this channel today

But that's a very good piece of information

thanks you 👀

[trail hazel]

when you edit your scripts, unity has to build a version as part of Assembly-CSharp (UdonSharp reads data from the compiled version, as opposed to reading the source code itself). because UdonSharp has to use reflection on it to build the program sources in the editor, it must be present from the perspective of the editor as opposed to the engine, and so changing it causes all editorscripts to be recompiled and loaded

this means that during this freeze unity is effectively unloading all of your editor scripts, compiling everything as part of a single assembly, and loading it again (and so you might notice the VRCSDK 'flash' when this occurs)

[twilit hawk]

Ah ok, a much better response, thanks!

[trail hazel]

the freeze is kind of unavoidable if you're doing quick testing, but what can help is making your unity install an exception in your antivirus and windows security (so it doesn't get profiled when the build tools start up)

[serene moat]

You can go into your Unity preferences and turn off auto refresh if you don't want Unity to recompile every time you modify a C# script

[scarlet lake]

i asked in the world dev chat about changing fog at runtime, apparently UDON can do it?
i want to have the fog clear during the night but then come back as soon as the lights turn on, the world is a remake of SCP-3008: Lone Survivor, but obviously modeled different ect, i have my day/night cycle somewhat working but the fog remains the gray color it is at daytime ruining the pitch blackness of the map, does anyone here know how to toggle fog off during the night parts?
the day is attached to a directional light if that helps

it uses the unity fog lighting system as particles would lag too much because of the maps size

even if its just changing the color of the fog id be fine with it

[paper plinth]

u tryna use an animation?
Or do you want to control the color of the fog by accessing the renderer with a script maybe?

[scarlet lake]

the fog is using unitys lighting system, i considered particles but the maps size would make it lag like hell

the map is sized at 2500x2500

so X2500 Z2500

i want the fog to just not exist or be black at night

but during day

it would be the grey/white color it is now

i have my week day/night cycle working using a animation that toggles them on and off

@paper plinth

if theres another way to render fog id use it

as long as it doesnt cause lag

as the world scale is massive

[paper plinth]

I wonder if you could just control that aspect with a script like you can with material settings

[scarlet lake]

maybe

unity scripting isn something i know how to do

don't know C#

just some basic JS and discord.js stuff

ive seen in the unity docs you can use scripts to change the fog during runtime

but

no clue how to use C# scripting

so the knowledge of that is useless to me

[paper plinth]

You can probs just do it in nodes, find the renderer and access the fog. I'm not in front of a PC or I would look

[scarlet lake]

ill have a look later

for now i need to focus more on the map details

what i really will hate doing is making every single chair, table, bed and lamp, grabable and moveable, they will not have gravity but doing that will allow for people to make bases

[paper plinth]

Search by type or tag in unity and apply the pickup component all at once

[scarlet lake]

would that just allow for that one item pickup?

or all of them?

[pastel sinew]

why don't they add a way so keyboard players can can move there hands

[dapper lion]

so, there is technically a easy “live hack” where a desktop user can hold an object thats invisible and their hand is up, but youd have to make like screen graph and a lot of controls to make something like the AS desktop object grabber

thatd would probs be the easiest way to script something in since it can be done with extra keybinds and tracking

[scarlet lake]

another way is to have them controlled as a emote in your menu

[void ridge]

I suspect this person is just asking for a feature request for VRChat in general, which belongs on canny, and they're in the wrong channel

[scarlet lake]

if your using 3.0

think of it like this remote but it controls each arm

@dapper lion

it is possible but you would have to set the avatar up to be able to do it

but most likely say bye bye to any VR usage

as they loose the ability to be arms that way

so your actual arms are invisible

[dapper lion]

yea, you can probs set up a radial that can move your hand around

probs add a enable and disable function

like that image

however that only applies to that avatar

[broken bear]

We now have parameters if they are in desktop, 3pt vr or 6pt now in avatar 3.0, so you could run an animation in a way for desktop only, but I don’t know if those parameters are available in udon

[dapper lion]

i think wed have to move bone positions based on keys. but it would def be wonky since its never really been done

avatar 3.0 would def be the easiest solution. but it wouldnt apply to all avatars which is probs not ideal

[broken bear]

I’m sure there’s a proxy_holding animation in av3 that can be copied over that the world could run but like you said it’s the desktop check, not sure of that status is available in udon, though it is part of the player component running at least client side so maybe it’s accessible by u#

[paper plinth]

if you had a hundred pickups, you could set one up perfect and just copy and paste the components into the other 99

[dapper lion]

so question, does udon worlds not support the default quest keyboard that usually appears when you click on a text box?

[scarlet lake]

wait so if i setup a UDON code for one pickup, i could just clone it

and get like several hundred more?

[paper plinth]

Ideally for similar pickups you would have one script and maybe only change the references

I have a world with a few dozen little globes that you shoot at

[scarlet lake]

fair enough

i can just give all my objects the same physics

as they do not really need anything different

as theres no gravity

does having alot of pickups lag the world at all?

just want to know before i start this

i know ones with physics will because good god the physics

but ones that dont shouldnt lag right?

[dapper lion]

yes, especially if they have gravity and they try to collide while synced

[scarlet lake]

alot of the models in my ikea also use box colliders

as its cheaper

than mesh ones

few things use mesh colliders

[dapper lion]

i think even without physics, they add some performance drop, its just not as bad

[scarlet lake]

yea

ill have to experiment

as i want to have a unique thing as i havent seen many worlds that allow for building

[dapper lion]

i think anything with rigid body usually cause a tiny bit of lag

and if you hve like a billion synced objects, that cause also cuase other issues

[scarlet lake]

the only other SCP-3008 map is pretty bland, no hate to the creator, they had a good idea, just could have had better execution

thats what i plan to achieve with my 3008 vrchat remake

i mean i have my whole week day/night cycle mapped out

just need to get the fog to disapear at night

[dapper lion]

i think there is an environment slider somewhere but I don’t know if it still works or even exists

[scarlet lake]

yea

my fog uses this option however

hold on let me load up unity

also my map allows for flashlights, but i will provide my own too

[dapper lion]

i cant open images but im assuming its the lightmap options?

[scarlet lake]

in short my world uses the built in unity fog option

the one that fogs up objects but the skybox is left visible

its why i completely enclosed my world

[dapper lion]

i feel like that is exposed in udon but I don’t know if anyone here has done it before

[scarlet lake]

thats how i am doing fog currently

i might just temporerally remove it

unless theres another way

this is what night should look like

pitch black

outside the lamps and overhead lights in the show off areas

without the fog though the world looks fking wierd

you can even see the top of the world

[dapper lion]

some world creators use particles for fog. I don’t know if youve considered that

[scarlet lake]

i have

but uhh, the world is 2500x2500 it would be VERY laggy

if only there was a system like unitys fog but it wasnt

[dapper lion]

possibly make the particles only spawn near by

[scarlet lake]

yeah but the other issue is they are not instant either

as the lights in the IKEA literally just go BANG full daylight

wouldnt be surprised if it sent people blind

[dapper lion]

you could also do ths stupid idea : make a sphere around the player that looks like fog. and all you could do is either edit the material or disable the sphere

[scarlet lake]

that is a good idea but idk how i could fade it in

nor do i know how to make it sync to the player

and only that player

as you could overlap spheres

[dapper lion]

you can tell the sphere to track like their heads and make the sphere not sync between clients so everyone has their own sphere

[scarlet lake]

i did see volumectic fog would work, but the issue there is i need to create a whole new project

and yeah no

and overall i have no idea how it would work

[dapper lion]

odd

[scarlet lake]

or if it can be changed in runtime

when i eventually figure out how to make color of the fog change on day/night change ill do it

as since i have 3 types of weather now, Day, Night, and Blood night

blood nights happen every sunday night

if i ever get into adding any form of AI (as i know its possible)
ill add employees in

[dapper lion]

thatd be cool. but as i said, its like a really stupid idea cus im pretty sure there has to be a way to edit the fog. i just dk what the namekey would be

[scarlet lake]

yea

i did see C# scripts work

but

i have no clue how to script C#

[paper plinth]

it's easier just to rip off people's scripts and remake them in graph

[paper plinth]

my quicksand is too real
there's literally no way out

[paper plinth]

how do I get the jump button? I can't find it on any of the input cheat sheets

well you need to set your jump impulse to something not zero

it's in the vrcworld prefab

one of the public variables for the world script

[paper plinth]

I don't like the defaults

[paper plinth]

it's in rendering settings

just get the color from somewhere else

[fiery yoke]

Animation events

[paper plinth]

yeah if you just want it to switch on and off use an event

or black to grey

if you want it to get progressively darker you can hook it to a value, there's ways to multiply colors

I have a light that changes color by an animation already and I just went off that

but if you want instant bang dark use an event and shut it off or drive it off the same event that makes night happen

disco fog is pretty goofy

what does it toggle?

I mean on the light

what part of the light do you toggle to make it turn off

set active?

ok so game object is active

probably something like this but keep in mind active self will only check if the object is active because you set it that way
if it's not active because a parent object is not active then this will not work

just don't get fooled

yup

render settings

[waxen breach]

Hey im trying to make a system where you can select a player by their id and it do something to that player. But since udon as far as i can tell does not reuse id's so to prevent it from breaking i tried to use the new isValid for the VRCPlayerApi. Although when testing it always seams to go false. Am i doing something wrong here?

[somber hawk]

What's the recommended max length for a synchronized string?

[fiery yoke]

Depends on pretty much everything. For a single object, and a single string the max length seems to be around 125 from what I heard. But its all fuzzy limits and tons of factors.

[floral dove]

how are you saving / setting those IDs in the first place? FYI if you use the generic IsValid node instead of the VRCPlayerApi verson, you'll get a branch built-in to it

[waxen breach]

i just figured out it was just something weird in testing. i uploaded it and joined the world and it worked. Also im using jetdogs player list to show the id number and to select it im using a slider. im currently working on a moderation menu for worlds. I will most likely make a public version soon once done.

[somber hawk]

Gotcha, for mine the worst case right now is ~50 or so. Just wanting to make sure I don't hit the limit since it seems to end up breaking things when that happens 😂

[fiery yoke]

There is only a limit for the overall outbound data and per behaviour. How those limits look like or which data type contributes how, is unknown to me, as its not documented anywhere.

[paper plinth]

Is Fire2 the jump button?

good show

badass

the grind continues

yeah I hooked mine into to a constantly changing disco light and it was real horrible

transform.position += Vector3.forward
what is this in graph?

[unborn hornet]

@paper plinth

[paper plinth]

thx!

[dull trail]

is there a nice simple udon mirror prefab someone can link me?

[twilit hawk]

Move the items to a new layer, then go Edit > Project Settings > Physics, and tick only the player, and playerlocal boxes (and any other layers you want them to block) in the collisions matrix.

(for the new layer)

You might also want to check out the edge case of a player picking up an object that they're standing on. If it launches somebody into the stratosphere, you might need to add some Udon to turn a collider into a trigger while it's held.

[somber hawk]

The SDK comes with a prefab VRCMirror.prefab and some examples which you can copy/modify accordingly

[edgy moss]

I'm having a very interesting issue. I'm specifically working on a Quest world. And let me preface by saying I am admittedly pushing the quest 2 right up the the boundary of what it should handle. I have a lot of heavy meshes, particles, shaders etc, so it's certainly not the MOST performant world, but it's still pretty decent considering, and i've optimized quite a lot. The issue is, I have a few pickup items in my world that have scripts attached, (for instance, the basic rainbow QV Pens set) and when I pick them up, my frames drop A LOT. Now I know this is natural to some degree, especially since like I said I have a lot going on. HOWEVER there are a few aspects that tell me there's more to it than that.

1. When I pick up the objects and move them through space, I drop to 11 frames per second. No more, no less. Exactly 11.
2. When I first spawn into the world, I have this issue. BUT if at ANY point I respawn, whether it's by the respawn button, or by travelling through a teleporter, after that point the pens work perfectly. Consistently, without fail, the pens are broken, but only until I respawn at least once per instance. So my solution was going to be to just have the player automatically respawn upon arrival and problem solved. BUT unfortunately,
3. this fix does NOT work if there is more than one player in the world.
   So it's super wierd, and is not just about performance, but networking as well. I'm hoping this is a known issue with a fix. Any ideas would be greatly appreciated!

[unborn hornet]

Does anyone know the exact position offset and direction of the VRC default UI raycast pointer? I have a need to replicate that info with precision as a custom raycast. I've gotten close but there are edgecase angles where it doesn't align. (Hoping momo or one of the other devs sees this 🙏 )

[misty hedge]

Hi so I am very new to making maps but I really would like to, currently I am running into not being able to load into my would. Did I do something wrong?

[unborn hornet]

Are you using the Unity play button or are you using the VRCSDK Build & Test button?

[misty hedge]

VRCSDK

Like in game I can't load into it

[unborn hornet]

Do you have the VRC Scene Descriptor script add to your scene? If not, try adding the VRCWorld prefab to the scene.

[misty hedge]

Thank's let me see if that fixed it

[unborn hornet]

Also, make sure to update the walk/run/strafe values at the bottom of the inspector for the VRCWorld object. I've had times where the all 0'd out and had to change them to be able to move in game lol.

[misty hedge]

Yes thank you it worked

Ok now quick question why cant I collide with the prototype props?

Are they just their for scale/model of what to make?

[unborn hornet]

prototype props?

[misty hedge]

Oh its a model

It's these things that come with VRCSDK

anyways thanks for the help

[terse musk]

how does onRenderImage working?

[floral dove]

sorry to say that it's not as simple just an offset and direction. However, you can add an invisible UI layer over an object to force the pointer to show and then accept that event and send it along

[unborn hornet]

More specifically I need to be able to get/recreate the exact pointer hitpoint on the UI's collider so that the player can interact with the UI whilst holding a pickup, which normally prevents the UI pointer from showing up.

It's explicitly just a visual feedback problem related to pickups and UIs.

[floral dove]

ah gotcha.

I don't think I have a solve for that while keeping the UI, but you could add your own actual raycast to an object with a collider

[unborn hornet]

That's what I'm doing atm, but the alignment is never 100%, and I keep getting reports that players find it's accuracy problem annoying.
I'll re-angle the question maybe. Is there a way to get the hit position of the raycast off of a UI collider? I can fake the source point easy, but the intersection is what's needed for the "phantom" pointer to aim properly. if not that's understandable. Just spit-balling for a raycast of hope.

[floral dove]

not as far as I know, sorry. But I appreciate your pun fwiw

[unborn hornet]

Alright. Thanks for responding. I'll try to find a work around...

Unrelated curiosity: [Is there a/what is the] maximum number of uasm instructions that can exist in a single script?

[floral dove]

Yes, there are a few different limits you could run into but I don't have numbers. Would be nice to document somewhere but it's not a common occurrence to exceed them afaik.

[serene moat]

I think the instruction limit is pretty much just uint max so around 4 billion, which you're probably going to run into other issues with beforehand

The heap has a maximum size which people used to run into, but it was raised to 1 million heap values which again you'll probably run into scalability issues before you hit it

[unborn hornet]

Neat

[lilac hatch]

Before I'm looking into stuffs i'd like to ask here, is there a simple way with udon to know if a player is currently calibrating his FBT ? :o

[native estuary]

That's a really good question honestly would allow for something like showing a automatic mirror in front of the user for calibrating

Def possible but not sure how simple

[lilac hatch]

That's what i had in mind :)

Spawn a local small mirror for em, i'm a bit annoyed about having to look for one when my tracking decide to yeet itself

[native estuary]

If I was on a computer rn I would try to come up with some ideas for you but sadly I'm heading to work

[lilac hatch]

all good eheh, i'm heading to bed tbh right now ^^

[paper plinth]

Potentially you want kinematic objects and then script the interaction with each other, like making the cubes stack up straight

Yeah then a lot of game physics won't act on the object at all

If you're trying to create building blocks that snap into place, that is

As a rec room player I have opinions on how base building should work

Because it ends up working and looking like crap lol

Because the cube stacks aren't straight T

Straight

Looks like a stack of boxes in a storage unit

Instead of a base

There was a guy in here who did legos
His only issue was you can't parent two objects to the same thing at the same level

So linking a 2x2 to a 2x4 was a little problematic but he was so close

Including having the resulting object respond to physics

Those are pretty straight

lol

You can get around that with baked area lights and such...there are big boys who will delete the directional light and build it all themselves

Are those chairs pickups that you can't sit on?

Thought so

In that case I think you're good

The trouble is if they're kinematic you need to script them so the orientation is right when you drop it

Like put y on the next object down and orient it to the nearest 90 at least

Or 45

And orientation is pretty easy, just pick an object's rotation and use it for everything

Take the eulerangles, pull out the right axis, round it to the nearest 45, plug the noodle back in

One thing that helped me out quite a bit in the beginning was creating another scene in the project and importing pickups, and putting settings on in different ways, and then interacting them for a while to see how the settings affect the way the objects move

I'll release the quicksand prefab today maybe

[storm scarab]

???

[paper plinth]

They'll put out their real-time light

Well I don't think you can set them to mixed or baked if you're going to move them around, I don't think it works that way

Put a cube at world 0,0,0 and put everything at scale 0,0,0 world position 0,0,0 until you need it

You can also make an inside-out dome and set it as a trigger and respawn objects that hit the trigger.

[broken bear]

I can’t tell by the screenshot, Is the object distorting when moved

Make sure all of its parents in the hierarchy are scaled at 1,1,1

I just had this issue last night

[dapper lion]

ive seen that before. I don’t know how people fix it tho but I think 🤔 its cus of its armature or something

they probs have something extra for some reason like armatures or weird LODs

also theres this weird glitch that rarely occurs when you change your avatar. certain meshes will expand or shrink depending on avatar size. I don’t know if that could also be happening

is the thing static?

[broken bear]

I had the same pickup object scaling issue last night and it was fixed by changing scaling of patents to 1,1,1

Oh sorry I typed that already

[dapper lion]

makes sence

[paper plinth]

The best way is to just play with it until you find the combination that works....i ended up ditching pickups altogether

[dapper lion]

i dont think ive made a pick up object on purpose for 2 months now

[broken bear]

This all may be better for #world-development for progress updates to the world

[dapper lion]

thats cus world dev was supposed to combine both basic standard dev kits

its not sdk2 exclusive

i dont see that

hmm odd, but i dont really see any reason why itd be sdk2 only. plus it says “questions” not discussion sadly so I have no idea then, either way id post in world dev as no one reads the description either way

i dont even see a description

ye

[somber hawk]

In some open source code I saw this check included, is there a particular reason you might need this?

I figure this wouldn't be called if you are the owner, but is there a possible race with ownership changing hands?

[floral dove]

@scarlet lake you've been flooding the channel a bit - you're welcome to share significant updates in #udon-showoff and ask udon-related questions here, can you please take your 'dev blog' style updates to another channel?

[floral dove]

Ah, interesting. I don't know of any situation where this event would be triggered on the owner of the object, it might just be a case of being super-careful.

[somber hawk]

This was seen in MerlinVR/USharpVideo if helpful, maybe they know 😄 There's also some interesting logic around deserialization where they use a counter to try and avoid some problems

[fiery yoke]

I know why that is

And its sort of a bug

After becoming owner of a gameobject again you still receive OnDeserialization events from yourself sort-of

Its a little complicated, but essentially you will receive old data from yourself. No idea why that is, but it has been a long standing bug that has been reported multiple times afaik.

[somber hawk]

So is it good practice to throw that logic into any object that transfers ownership a lot with synced variables?

I definitely saw that behavior when I tried to implement multiple people controlling the default graph video player

[fiery yoke]

Ohh actually I think Im mixing it up with something else

[somber hawk]

and switching to merlin's fixed it

There is a comment about that in the code

[fiery yoke]

There is a few weird bugs regarding networking at the moment, with multiple different guards

[somber hawk]

https://github.com/MerlinVR/USharpVideo/blob/master/Assets/USharpVideo/Scripts/USharpVideoPlayer.cs#L594

[fiery yoke]

that is just a guard to make sure that nothing unintended happens-

Yeah there is another way where you just ignore the first few deserializations after becoming owner

but this should be effectively the same and shouldnt cause any problems

[somber hawk]

Follow up question to improve my understanding of this logic, I thought OnDeserialization was only called when a variable was changed, how does this counting up to 10 work if there aren't 10 changes? Does it send on an interval or something instead?

[floral dove]

in the current networking system, it's more of an interval, yes. It can be called when any variable changed, not tied to a specific one

[somber hawk]

Cool cool, is it any (synced right?) variable on the specific object with the handler or on any object in the scene?

[fiery yoke]

VRChat uses a (probably) heavily modified version of PUN. Their networking architecture is very similar to that of general P2P, however the data goes through a middleman (the Photon Servers).

Currently Synced Variables of some behaviour are serialized by the networking owner of that behaviour every "network frame", send to all other users connected to the instance/room and are then deserialized on the corresponding behaviour.

There are two events called "OnPreSerialization" and "OnDeserialization" relevant for this. Note that serialization only takes place when two or more users are connected to an instance.

Network Events are essentially named RPCs. They are sent from an instance of an UdonBehaviour component to the corresponding behaviour on a remote client.

Thats pretty much all there is to know about the fundamentals of VRCs networking. Ohh and networking data is badnwidth limited, per-variable and per-behaviour and there is an absolute global limit across all behaviours. ( I believe)

That is the message I typed out a few days ago

Thats pretty much all the generally available knowledge compressed into one paragraph (bugs aside).

[unborn hornet]

Detect bone rotation to see if T posing? Lol

[lilac hatch]

🤔

[misty hedge]

how does one make it so these textures are the same scale?

[floral dove]

#world-development may be a better channel for learning about textures and uv mapping

[misty hedge]

thanks

yeah I thought I should since their might be a better solution

[paper plinth]

is there no gameobject.get tag?

like if I want to check a collision and see what tag the other collider is

get tag

THANK YOU

[floral dove]

check #faq to learn where to ask different questions. This channel is for questions about Udon, our custom programming language for VRChat worlds.

[sage obsidian]

ok

[paper plinth]

can I make an array of float arrays?

[floral dove]

we don't support multidimensional arrays at this time, sorry

[paper plinth]

all good I don't know how to do it anyway thx

would have to look it up lmao

tryna make an inventory system with object IDs

in the past I would just make my own custom data structure but I don't see where you can do that either

[floral dove]

the only usable collection right now is an array.

[paper plinth]

that's a lot more than they gave us with a slc500 honestly

[floral dove]

we don't offer custom data structures as every type has to be compiled ahead of time

[paper plinth]

there's tons of array types

[floral dove]

the closest thing to a custom data structure is the symbolTable on an UdonBehaviour itself, which is a string-to-object lookup

we generate every Array Type ahead of time

[paper plinth]

I think that's probbaly the best I can do

[floral dove]

it's one of the reasons we've held off on introducing Lists. It's not just List, it's List<bool>, List<int>, List<object> etc etc

and Dictionaries...oof

[paper plinth]

I can store at least 9 floats in the transform of an empty gameobject if I can figure out how to find the object

like if I can concat the playerid onto the end of a string like Inventory1 Inventory2 and make those gameobjects the data structures

[floral dove]

well,you can inline your values instead of arranging them into a multidimensional array. Like if you wanted an array of three float[3] arrays, you'd just make a float[9] and just offset your lookup

[paper plinth]

could probably do a lot with that

sure

[floral dove]

automatic sync will not be coming, we're removing that disabled button.

you can sync it yourself

[paper plinth]

so I get the player id that's holding the handle and I multiply it by 10 to offset the array, and then add an object ID from 0 to 9 and increment the integer to count how many I have of each ID. It's an array of 1024 ints. Any opinions?

in the above I harvested a green flower

[paper plinth]

lol just rip off other folks

[stark fiber]

Did you ever solve this?
Just been hit with this myself and struggling to find why

[paper plinth]

U need to restart unity

[stark fiber]

Restarting does nothing

[paper plinth]

That's a little different lol

The problem is in your script

Did you just install Odin Serializer?

There aren't a lot of programming contexts where you start with literally nothing.
At minimum you have templates and standards documents to guide you, and requirements and specifications that define what needs to happen and how.
So it's natural to use other people's stuff. It's never going to be a perfect fit but it's pointless to blaze trails when there are well traveled roads for routine stuff

[muted basin]

What does animation syncing actually mean?

[unborn hornet]

Syncing values of some kind, and adjusting animations locally based on the values.

[agile vigil]

Is there any way to make it so a world "remembers" your progress, somehow?

[floral dove]

nothing built-in to support this, yet. I've seen some people offer a text box that generates a string based on some world data that you can copy to save data, and paste to restore it.

[agile vigil]

Ooo

A password of sorts

[floral dove]

yep

[agile vigil]

At the same time, it may be a bit intensive with what I want to use it for

[floral dove]

ye

[summer scroll]

deleting the SDK then reimporting it

[broken bear]

Can U# access and/or set local avatar synched parameters? Like if a script knew what to look for, could it read/write that parameter locally on the player.

if so then the world could use a password avatar that can use the av3 128 bits now to set the parameters that save locally, and then could be read at a later time. the avatar is the save file. I think I know the answer though

[unborn hornet]

Udon cannot directly read from, alter or affect the player character except for the API available on the VRCPlayerApi type.

[fiery glen]

Does anyone know how many youtube videos can be played in one scene with UdonSyncPlayer (Unity)?

I put two UdonSyncPlayer (Unity) in the scene, the second one won't work

[viscid reef]

video players are rate limited to loading 1 URL every 5 seconds, this limit is global for your entire map

if you have multiple video players you need to stagger their loading of urls

[fiery glen]

What does it mean?
If I have one video of 30 seconds and another video of 20 seconds, how do I stagger their loading times?

[viscid reef]

it means after you load video 1, you have to wait 5 seconds before you attempt to load video 2

[worldly wolf]

so dumb question to ask but what is UDON

and why has it come to vrchat.

is it some new scripting code? some kind of editor?

[fiery glen]

Then why do I check the loop parameter, the film will not loop, and check auto play, the beginning of the enter also did not automatically play

[viscid reef]

because if you just put 2 video players down

[viscid reef]

when they start playing at the same time, 1 will succeed, and the other will fail with a rate limit error

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

see section on rate limiting

if you're going to have more than 1 video player, then it is a must for you to handle their loading in your udon behaviors, be it with a delay, a queue etc

[fiery glen]

But Udonsharp doesn't have the syntax of IEnumerator or yeild

[viscid reef]

you're going to have to handle the logic of it yourself with whats available, to ensure a url is only loaded once every 5 seconds

[fiery glen]

Okay, I'll give it a try, thank you!

[robust drum]

Is the object syncing system changed at last update?

It seems maximum time of position lerp became unlimited at last update. That means any object teleport are replaced lerp movement that takes the time of last position update (on non-owner sight).
Example: If the position is updated after 30 second of last update, the object moves to synced position taking 30 seconds on non-owner sight

[paper plinth]

@scarlet lake Maybe make the audio source only play if you're inside collider bounds

[misty hedge]

how does have a switch to like toggle between 2 objects

like if one is off the other is on type thing

[dapper lion]

have it toggle 2 objects at once, so it disabled the enabled and enables the disabled

[misty hedge]

Mind showing me how to do that?

a screen shot is enough

[dapper lion]

sorry, not at pc until like 10 or so more hours

if you have udon sharp, there should be a interact toggle script that allows you to do more than 1 thing

[paper plinth]

I made some switches in #udon-showoff lol oops literally almost tagged the wrong person @misty hedge

Hello! I'm trying to debug something that needs OnDrawGizmos, but apparently there's no a node for it, which is kinda weird considering we have the other nodes to draw gizmos, is there's some other event I can use instead of OnDrawGizmos or I can't use those nodes?

[fiery yoke]

I thought those were added a while ago...are you sure youre on an up-to-dare sdk? x)

[dawn plover]

Yup, I've downloaded the latest one, I have the nodes to draw Gizmos (like DrawWireCube and other stuff) but there's no OnDrawGizmos, so I can't actually use them lol

[fiery yoke]

That was noted before...and I thought that they had actually added them...

[shut patrol]

came to brag a little about gizmos
Oh, i forgot, the code for this example:

void OnDrawGizmos()
{
    Gizmos.DrawCube(transform.position, Vector3.one);
}

[misty hedge]

So what is it?

[shut patrol]

A weird cross between unity and udon functionality. Experimenting with my IL code postprocessor (or a compiler?)

[brittle pebble]

Does anyone know how to make pickable objects global?

[hardy fog]

I think there's a check box for synchronize position

[brittle pebble]

In VRC Pickup?

[hardy fog]

Mmmh, if not there, then on the standard VRC behavior / (Udonbehaviour as THH said)

[fiery yoke]

its on the UdonBehaviour. Just add one with an empty program

[brittle pebble]

Thank you so much ^_^

Also is there a way to add a collider on a player in Udon?

[agile vigil]

Quick question, I want to set the spawn points for my world, so I go to my SceneDescriptor, but there's no way for me to tell it which objects I want to set as spawns

Is there something I'm missing here?

[fiery yoke]

Spawns is an array, it only gives you slots if you set the "Size" to something greater than 0

[agile vigil]

O

nice

[paper plinth]

you can
on interact
use a right thumbstick up (bool) to cycle it through your rotations

I do this on the switches I posted above, there's a slider that's 0-10 integers

for whatever reason, when I harvest a plant from my harvester, my text display freezes in position and stops letting me turn it active or inactive

doesnt' matter what hand I do the harvesting with

that's the collecting script

for some reason it causes my text display to just freeze there

[fading cipher]

When you accidentally leave Unity in play mode overnight https://i.imgur.com/UEJSjo3.png

[serene moat]

re gizmos: you can register a custom event named exactly _onDrawGizmos in the graph and it will fire the proper event to draw gizmos in Unity. Udon doesn't register the event as a node, but it does exist and gets called if it's named properly. The main downside which makes it very limited with that method is that Udon code does not run in edit mode so you need to be in play mode to see any gizmos. So they're only useful for debugging game logic and aren't viable for providing editor markup. If you're using U#, there is handling for running gizmo code from edit mode via the editor scripting systems https://github.com/MerlinVR/UdonSharp/wiki/Editor-Scripting#using-gizmos you can also use Handles similarly

[dull trail]

anyone know how to set up that thing where video players "emit light" based on the video?

I believe you'll want an Emissive material: https://docs.unity3d.com/Manual/lighting-emissive-materials.html

[elder bridge]

why is the public variables box glitched

i checked for errors in consoles, it doesn't have any errors

[floral dove]

does it look like this on the actual UdonBehaviour or just the program asset?

[elder bridge]

how do you check that?

i just picked up udon recently but this prevents me from doing more progress to the world : (

[floral dove]

It looks like you've selected the program asset in your project. What does this program look like when it's actually on an UdonBehaviour in your hierarchy? The UdonExampleScene, for example, has lots of UdonBehaviours on objects, do they have this issue?

[elder bridge]

i'm not sure where i'm going but that's the example scene and the public variable is bugged for one of the things
i'm probably lost
i'm probably not looking at the right place maybe

[floral dove]

It looks like you're just getting started with learning Udon. That's great! I recommend you watch this video to learn how to open, inspect and build your first Udon world: https://www.youtube.com/watch?list=PLe9XHNvXcouQjg5GULWGLj1tMzeythnQi&v=8yaQY0arCnc&feature=youtu.be

Once you're up and running, I recommend reading through the "Udon Node Graph" articles on our docs which show how to use the node graph to build your programs: https://docs.vrchat.com/docs/udon-node-graph-upgrade

[elder bridge]

i already read the docs, but guess i'll reread again : |

need to remember some stuff again

i was just trying to build a mirror toggle button

[floral dove]

in this case, you need to click on a Gameobject in the Hierarchy window instead of in the Project window.

The example scene has a mirror toggle button you can use as an example

[elder bridge]

ahh gotcha

aight it works now
cheers

[wintry radish]

Hey there. Just a quick question. What exactly is the difference between "is Master" and "is Owner" in Networking?

[misty hedge]

Owner is the map owner and Master is the instance Master

[fiery yoke]

No

that is wrong

[misty hedge]

well

I was guessing

[fiery yoke]

https://docs.google.com/document/d/1PuqqbIalSNLvOISgVyRKtPOHY-8i6ZH6vLJTTIF9rAc/edit?usp=sharing
I will refer you to this document I wrote

[floral dove]

generally, you want the owner of an object. The Master is either the person who started the instance, or the person who took over from them.

[fiery yoke]

IsOwner refers to the "Object Owner" section
while IsMaster refers to the "Instance Master" section

[floral dove]

They will be the owner of all the objects when the world first loads, but that can change. Generally, you care more about who is the current owner of the objects.

[wintry radish]

Okay. Thank you. That's what I needed ^^

[rigid plume]

How do I send a custom event to another GameObject? SendCustomEvent accepts an instance, but it is of type IUdonEventReciever, which doesn't even show up in the type list.

[fiery yoke]

The graph is not telling you the whole truth there, UdonBehaviours are IUdonEventReceivers, so you can send it to an UdonBehaviour

[rigid plume]

So if I get the UdonBehavior component of the object I want to target and connect that to the instance, I should be good?

[fiery yoke]

Yes

[rigid plume]

Cool, thanks!

[rigid plume]

When you send custom events, are they executed in the order they're sent? Do I need to be wary of race conditions or multiple threads?

[fiery yoke]

Udon runs exclusively on the main thread, for local custom events they are executed in order.

[hushed gazelle]

What's the best way to trigger a particle emitter with Udon? Just needs to fire once consistently when told to do so.

[foggy perch]

so i just started up my game and all my models i uploaded veiw points are broken in game when the view point is in the eyes and such, public models views are find but it is broken for my models idk why

[hushed gazelle]

You want avatars, this is for Udon worlds.

[foggy perch]

sorry :p

i thought udon was also for like unity or something

[lilac hatch]

sometimes i wish the Local testing was an actual local testing.

so i could still work on stuff when the servers are down

https://cdn.discordapp.com/emojis/662111969003962401.png?v=1

[fiery yoke]

The testing is actually local. But VRChat is a SaaS type thing. You cannot use the service without logging in, which requires a connection to their servers.

[lilac hatch]

Yush, it's a bit sad tho :(

I used to go with at least a good 4-5 days w/o internet a year ago, could've used this time to do a lot of testing instead but meh

The servers usually get fixed pretty quickly so

Just gotta wait

[scarlet lake]

are the servers down right now or is it just my game?

[mystic flare]

Servers are down but @drifting sage is trying to fix them

[scarlet lake]

oh ok

[lilac hatch]

yeah U GO TUPPER

FIX EM

[lilac hatch]

https://niyah.eu/i/58629.png

Yeah, hm.

^Happen when i'm trying to upload an update to my world, unsure of what's up, guess it have to do with the servers going madlad earlier :(

[silent gazelle]

Any possible way to sync door position/animation?

[paper plinth]

I have a particle emitter that emits a 1s program when I set the gameobject active and so when I want a little burst of particles I just wake it up and put it back to sleep when it's done

[hushed gazelle]

Oh I could fudge that easily enough with an animation, I was just curious as to if there's a proper way to tell a Particle Emitter "trigger once with an X particle burst")

[paper plinth]

That's all settings

[elder ledge]

Any easy way to add additional launch options from VRSDK + Unity when running "Build & Test". I'm trying to see Debug.Log statements, anyway to turn these on for debugging? If not, how does everyone debug udon graph programs?

[flint kite]

i think can use physics on roller coaster for udon?

[scarlet lake]

Anyone know why this happened when I added the Billiards Prefab in my world?

[broken bear]

make sure it's at Y=0, and you set up the collision layer. Also it needs udon sharp

[scarlet lake]

I think that issue is fixed in xiexes fork of the project

[dapper lion]

collision matrix is still needed

[floral dove]

The debug options are passed along automatically, make sure you have the path to the VRChat client properly set up in the control panel

https://docs.vrchat.com/docs/debugging-udon-projects

[scarlet apex]

how do i make a button with udon to switch mirrors? like, i have a button for a HQ mirror and one for LQ. i dont want to accidentally have 2 mirrors on at the same time so how do i get either button to turn off the opposite mirror?

i currently amd using Vowgan's object toggle thing

[paper plinth]

Use a branch

[tribal meadow]

hopefully this is something simple...but I've got an invisible box collider that is used to turn a mirror on when someone enters the box. The issue is, if a second person enters the box, the mirror shuts off for the first person, and turns on for the second....any ideas what I might have set wrong?

[scarlet lake]

So i was trying to update my world and this happened. Failed to delete previous version. I doin something wrong? Started yesterday when the servers went down.

[native estuary]

You'll need to contact support or just upload to a new id

[scarlet lake]

dang

ahh well at least it wasnt one of my public ones

[hardy night]

Uh hello there. I have a problem with using buttons to animate a door. Is this the right channel for that?

[rigid plume]

You're at the right place, @hardy night

What's your problem?

[hardy night]

So here's what's right: I have the buttons working AKA you can press them, the door has an animator that also works, and the animator has a boolean that lets you transition between states.

However, the problem is that I have no idea how to code it where the boolean of the animator changes when you press a button.

I've tried several times in C# (even using a C# to Udon compiler) and I don't know Udon enough to code it in there, so that's where my trouble is

[rigid plume]

If you're doing it in Udon#, you could do it with just an assignment like doorToggle = !doorToggle; (I think. I haven't used C# or Udon# really, so going off my experience with other languages). In vanilla Udon, you will need to have a boolean variable for your door. Let's call the variable doorToggle. In Udon, you'll hold ctrl and drag the doorToggle variable onto the graph to create a node that sets the variable. Then, create a new node by pressing space. Navigate through the menu to Boolean > UnaryNegation. Drag the doorToggle variable under that (not holding ctrl this time). Connect that to the left hand input of the UnaryNegation. Then connect the right-hand output of the UnaryNegation to your Set doorToggle node. That should implement the toggle for you. From there, create a Branch node connected to your Get doorToggle node. For the true branch, play the door open animation. For the false branch, play the door close animation.

[hardy night]

Okay so I have it but Im unsure if this is what I need. Let's see

How do I add this to the button?

[rigid plume]

You create a new Udon program and then add it to your button's GameObject as a new UdonBehavior component.

[hardy night]

Nah, I mean a UI Button

[rigid plume]

Ah, you'll need to create an Event Interact node.

[hardy night]

Where shall I place that?

[rigid plume]

First, you'll need to press space in the Udon graph editor, then choose Event > Event Interact. Put that on the left-hand-side (LHS) of your Set doorToggle node.

[hardy night]

So this will make my button change the boolean each time, it's pressed, right?

[rigid plume]

yes

Unary negation basically switches a boolean value on or off.

If it was on (true), it will be switched to off (false). If it was off (false), it will be switched to on (true).

[hardy night]

Like this right?

[rigid plume]

yes, that looks like it should do the trick.

you will also need to get those bool instances from the door's animator itself though.

For the part after the branch, I mean.

[hardy night]

How shall I get an instance?

[rigid plume]

First, you'll need to have a variable for your door's GameObject and make that a public variable. In the scene editor, be sure to assign the door itself to the door variable in your Udon Behavior component for the button.

Next, in the Udon Graph editor, you'll need to get the boolean for the open parameter from your door GameObject's Animator component.

To do that, drag your door GameObject variable somewhere to the right of the branch. Then create a GameObject > GetComponent node. Create a Type Animator node under that, and connect that to the type input for the GetComponent node.

Connect your door GameObject's node to the instance input of the GetComponent node.

Under all that, create a Animator > SetBool node. Connect the GetComponent's Component output to the Animator > SetBool node's instance input.

For the Animator > SetBool node, be sure to set its drop-down menu to (string, Boolean. Set its name input to open or whatever the name of your animator parameter for it is.

Then, drag your doorToggle variable under that to create another Get doorToggle node, and connect that to the value input of the SetBool node.

[hardy night]

So stupid question, how do I connect the instance of the door to the code?

[rigid plume]

You click and drag the little circle on the right of the door's node to the LHS circle next to the instance input of GetComponent.

If done right, you'll have a line connecting the input and output for those nodes.

[hardy night]

So everything should look like this, right?

[rigid plume]

Almost. Thinking through it more myself, I realized, you don't really need the branch. You can just connect arrows from the Set Open node to a single SetBool node (the uppermost one you have in your graph).

So, you should end up with a program that looks like this:

[hardy night]

Can I use this script on another button controlling another door?

[rigid plume]

You sure can!

Just in the scene editor, reuse the same script in the Udon Behavior component, but assign a different door GameObject to the door parameter.

[hardy night]

You mean the hierarchy?

[rigid plume]

By "door GameObject" I mean the object for the door itself, which presumably has your animator with the open close animations tied to your open boolean parameter.

[hardy night]

Shoot, it didn't work. The door doesn't open when you click the button. Anyway to check if the variable changes while playing?

[rigid plume]

You could create Debug > Debug.Log nodes to try to write your variables to your VRChat log file.

[hardy night]

Imma try to see if I can get it to cause the door to just open then progress from there to make it open and close

[rigid plume]

What does your animator look like?

[rigid plume]

In your program, is your SetBool's name "open" or "Open" (case matters)?

[hardy night]

"Open"

[rigid plume]

ok, the animator looks fine then.

[hardy night]

Coding can just get stupid at times, lol

Im gonna try out the "play" function and see if I can get it to open

[rigid plume]

That would certainly help to make sure that animator itself is working.

[hardy night]

Its best just to see if everything is working

[rigid plume]

In the scene editor, your button has the Udon program attached to it in an Udon Behavior component, and the door object set to its door parameter there, right?

[hardy night]

I dont see anything there

[rigid plume]

Looks like you need to make your door variable public.

[hardy night]

In the Udon Graph?

[rigid plume]

yes

[hardy night]

Nope, it's public

[rigid plume]

You're sure? If it were public, there would be a Public Variables section under the Open Udon Graph button.

[hardy night]

I think there's a problem with the compiler? It says "Object Reference not sent to an instance of an object"

[rigid plume]

In the Udon Graph editor, you should have this under your variables:

Can you share a picture of your Udon Graph program again?

[rigid plume]

No, that doesn't look right. Sure it would set your animator to the Door Open state, but it makes no change to the Open parameter, so it would immediately go back to the Door Close state.

I would recommend that you have your Udon Graph set the Open parameter of the animator instead of directly setting the Animator's state.

[hardy night]

?

[rigid plume]

That's closer. That would make it so the button always opens the door, but never closes it.

[hardy night]

Im just trying to see if it can open it

[rigid plume]

ok. Those are good first steps then.

[hardy night]

But Im still getting the "Object Reference not set to an instance of an object" error

[rigid plume]

To be sure that your Door variable is set to public, could you expand it out?

[hardy night]

It's public

[rigid plume]

Hmm... that looks fine there. It's strange that in the scene editor it wasn't showing the public variables.

[hardy night]

Should I attempt starting over?

[rigid plume]

Maybe try removing the Udon Behavior component from your button, and try adding it on again.

It could just be a hiccup with Unity.

[hardy night]

HAHAHA, It is the STUPIDEST solution I've ever seen. Apparently, I had 2 different programming scripts with the same name and they messed with each other

I see the Door variable now!

[rigid plume]

Oh no! I guess that would do it. XD

[hardy night]

Ah sorry

We did it!

It works!

[rigid plume]

nice!

[hardy night]

Alright, so it can open

Now lets see if we can get it to open and close

[rigid plume]

Now all you need to do is tie in that UnaryNegation bit and you should have a working toggle.

[steel nova]

anyone experienced this?

[cunning mist]

The servers are crapping their pants, don't worry

[steel nova]

i had this happen last night aswell, not during this outage

[cunning mist]

Try swapping the upload ID on the VRCWorld instead of overwrighting the old one.

[hardy night]

Alright, new problem: it won't close

[steel nova]

this is so odd

[hardy night]

Correction: it does close. It just loops the animation

[rigid plume]

In the earlier screenshot for your animator, I didn't see the condition for the transition from Door Open to Door Close, but can you confirm that it is Open equals false

oh

[hardy night]

Lets see if it works now

[cunning mist]

Make sure your Animation Clip file itself has Loop disabled.

[hardy night]

It was on lol. I must say, it is a bit weird at times such as like it takes a second for it to toggle again. Though that could be the animations being weird, it works!

[rigid plume]

Huzzah!

[hardy night]

So once I finish on some details, I need to add one more thing: a locking mechanism

[rigid plume]

I presume that'll be controlled by something outside your button?

[hardy night]

It'll be a secondary button. I was thinking it could be another boolean that changes another animator boolean, but it uses a custom event when pushed instead of Interact

[rigid plume]

If you're just changing another boolean parameter on the same animator, you might not need to deal with any custom events.

You could just add it as another condition on the transition from Door Default and Door Close to Door Open.

[hardy night]

I mean a custom event to change the new SetBool

Something like this, right?

[rigid plume]

You would need to modify your Interact event's workflow to check for whether it's locked.

[hardy night]

That's already done with the animator transition conditionals

[rigid plume]

ok, that should be fine there then. Do you have your lock button sending a Lock custom event to your toggle button?

[scarlet lake]

Udon looks really complicated to someone who's used to straight up text programming instead of GUI stuff

Is there some kind of non-gui version of udon or that the only way to use udon?

[rigid plume]

It is... I come from a text programming background too. XD

[hardy night]

Would the correct thing be UdonBehaviour.SendCustomEvent?

[rigid plume]

Yes, you would use SendCustomEvent. You'll need to be sure to set the instance input of that to the UdonBehavior component of your toggle button.

Otherwise, it'll use the this object by default.

[hardy night]

How can I be sure?

[rigid plume]

Your lock button's Udon program will look something like this, except remove the evtName node and just hardcode "Lock" for SendCustomEvent's eventName input.

[unborn hornet]

UdonSharp

[rigid plume]

You would set your door toggle button as the evtTarget public variable.

[scarlet lake]

UdonSharp? Sounds like a version of C# w/ some kind of Udon API and limited C# access?

Could I have some kind of link or page to read up on it. Sounds fun, really want to try it out

[rigid plume]

@scarlet lake https://github.com/MerlinVR/UdonSharp

[hardy night]

Oh no, it's being weird again. I have the "Object reference and instance" error again

[rigid plume]

What does your lock button's program look like?

[rigid plume]

You don't have anything flowing into your SendCustomEvent node.

Do you mean to connect an Event Interact to that?

[hardy night]

Wait... am I being an idiot or should I have just made a new script for this?

[rigid plume]

If this is controlled by another button, you should probably make a new script for it.

[hardy night]

I did and now they both have Interact and the same error

Oh, no, lock door doesn't have it 🙂

Its called NullReferenceException

[rigid plume]

What's your lock button's script look like?

[hardy night]

Nah, it's coming from the original script for some reason

here

[rigid plume]

Are you using the same programs on the Udon Behavior component for both your toggle and lock buttons? You should have separate programs for both of them.

[hardy night]

I have Open and Close Door on one and Lock Door on another

[rigid plume]

We already established that your Open/Close script was working on its own. Can you share your Lock script and can you confirm that the open/close button object is passed in as a variable to your lock script?

[hardy night]

Here is my lock script

[rigid plume]

Ah... For your lock script, you don't event need the Door variable. You can just delete everything to the right of the SendCustomEvent node. However, you do need a variable to take in your open/close button. You need to connect that to your leftmost GetComponent node instead of the LockButton. Since LockButton is this anyways, you don't need LockButton either.

[hardy night]

Huh? Isn't this script supposed to be used to a new button that controls another boolean in the Animator?

[rigid plume]

You could do it straight through just the lock button's script without custom events, but I got the impression that you wanted to do it with a custom event sent to your open/close button.

[hardy night]

Also, how come I need to add in the Open/Close button to the GetComponent?

[rigid plume]

The SendCustomEvent node needs an instance of an UdonBehavior object. You need to obtain that as a component from your Open/Close button.

[hardy night]

Oh! So the GetComponent is actually where the customevent will go to?

[rigid plume]

Sort of... it's the UdonBehavior object that gets forwarded from the GetComponent node that goes to the SendCustomEvent node.

[hardy night]

Alright so CustomEvent is what I use to receive the SendCustomEvent?

OH! resetting Unity does the trick 🙂

[rigid plume]

Cool! Got your locks working then?

[hardy night]

Too good. The door doesn't open anymore, lol

[rigid plume]

Like it doesn't open at all, or it doesn't open after being locked and then unlocked?

[hardy night]

Doesnt open at all

[rigid plume]

What do your scipts and animator look like now?

[hardy night]

Nothings changed to stop it from working

I took and put back in the udonbehaviour to see if that could work

Nope

[stark adder]

So world uploading is broken.. ? PERFECT -_-

[hardy night]

...Im an idiot

[rigid plume]

You figured out the solution?

[hardy night]

I didnt have it connected to the click of the button

I should also fix the delay of the closing animation

[rigid plume]

The closing animation delay might just be something to do with the exit time for the transitions in your animator.

[hardy night]

Hmmm, lock isnt working

but I can open and close it

Yep, I had it on a different toggle when you click it

[rigid plume]

You got it sorted out?

[hardy night]

I'd like to congratulate everyone and say it works!

[rigid plume]

Huzzah!

[flint kite]

hi i wonder can make physics like roller coaster made out udon. any idea?

[paper plinth]

Sure, that's just an animation

[flint kite]

?

[fickle stirrup]

@scarlet lake > #avatar-help you can via animations and puppet menu which av 3.0 provide https://youtu.be/VX-BoYUrUjM

[broken bear]

may be a stupid question but Ionly started Udon.. can a gameobject have more than one udon behavior script on it? I got an area trigger that I want to run two concurrent behaviors and doubling up the area trigger with a clone doesn't seem efficient

[stoic mountain]

I want to teleport someone, but not by interaction but by trigger. I want to check if the thing entering the trigger is a player and not something else. I was thinking of finding a "player" component in the collider/his parents but im not sure what to look for, nor that it is the right way to do it. Suggestions ?

(oh thats udonsharp btw)

[paper plinth]

If you want to teleport the current player you need to check player islocal

[stoic mountain]

I dont have a player at the start, I have a collider :|

[paper plinth]

And on playertriggerenter teleport to the (world) pos/rot you desire

Ohhh

Then you want ontriggerenter

[stoic mountain]

im curious about playertriggerenter, but ultimately I may need my teleporter to teleport other things as well

[paper plinth]

If you need the collision info then use oncolliderenter or whatever that's called

[stoic mountain]

        XXX playerObject = other.gameObject.GetComponentInParent<XXX>();
    }```
what should I use for "XXX" ?

[dawn forge]

Either put var to let the compiler decide the best type or mouse over getcomponent and see what the type is in the tool tip. Documentation should also tell you the type.

[stoic mountain]

Either im confused or there is a misunderstanding.
Any kind of gameobject can enter my trigger. When that happens, I want to check if that object is a player. So Im looking into the objects components to check if it has a "player" component. But I dont know what is the name of the component im looking for.

So that if the object has that "player" component I do something, otherwise I do something else

[fiery yoke]

Udon has a special method for detecting collisions with players. The one that youre looking for is probably "OnPlayerTriggerEnter"

[stoic mountain]

Wont the generic "OnTriggerEnter" method be triggered as well there ?

[fiery yoke]

yes. so what?

[stoic mountain]

so if I have code on OnTriggerEnter, and I want to check if its a player or a pickup that entered my trigger, I still need to check for that

or ... I instead of making conditions to check if the "object is a player", I could make conditions to check if the object is any of the non-players types the teleporter could accept. I guess that would work

[fiery yoke]

Well VRChat could have gone with a different way of providing a means to convert a player object into a playerapi, but they didnt. So yeah.

[broken bear]

kinda realted to my question above with this too, if I want multiple udon behaviors to run in a trigger area, should I duplicate the trigger area/collider (that doesnt seem optimized), or is there a way for the object to have multiple udon behaviors on it, I can just edit the U# to condense the behavior if needed but I don't want to do that if I don't have to

[stark adder]

Momo why the heck does GetPlayers return players in completely random orders.. ? -_-

[broken bear]

Also, is there a way to change world master within a node/script, no options seem obvious. Would like to have master restored when the intended master may rejoin

[stoic mountain]

UdonSharpBehaviour doesnt seem to have a OnPlayerCollisionEnter(), do I just type my method this way and hope for the best ?
void OnPlayerCollisionEnter(GameObject go) { ... }

[void ridge]

I don't think you can change master, but you can always set ownership of any specific GameObject with GameObject.set Owner

pretty much all master ever matters for is network ownership

[broken bear]

and room kicking

[void ridge]

Oh, is that how that works? First player in and then inheriting masters can instant kick? Didn't know that

I definitely wish there was more control over that

[broken bear]

yep they have a 1-hour kick option special to them without vote. Lots of troublemakers have antikick though, but I'm contemplating in the event someone troublesome gets the master role. Would love to have a button to assign master by whitelist

[void ridge]

As for this, no, I don't think you can have multiple UBs on one object. I might be wrong, but it'd be confusing if that were possible

I don't think there's really any problem with just copying an object so that you can have another, separate collider component

The soccer balls in Soccer Practice have three separate colliders on them, active at different times 😅

[stoic mountain]

(ok, found this : "public override void OnPlayerTriggerEnter(VRCPlayerApi player)", testing it)

[broken bear]

got it

I'm just trying to limit ways troublemakers can distrupt events. if Master is protected then it is what it is. issue: we have events where 1-3 troublemakers join on friends and distrupt. Plan to have a space 6000 meters away that will contain someone by a pre-set troublemaker list (on-enter area trigger to teleport them, and on-exit at the teleport area to pull them back in) or if someone new needs to be added, then an object a whitelisted player can spawn and collide with the troublemaker to add them to the troublemaker list. no idea how to graph that though so will just build on U# whitelist examples I have. Hopefully moded client teleport movement will still trigger on-exit of a trigger area. if not then I got to rethink this. I don't want the player space to be one collider with a constant check since that seems inefficient, only the spawn area.

[twilit hawk]

Alternatively, you can have an object that operates only on the local player (all of them) periodically, or in an event that gets triggered for everybody's instance if you want to drop the ban hammer, such as the trigger system you were talking about. If they're a banned display-name, then flip a local (unsynced) boolean.
That boolean is checked in fixedupdate, and if it's set to true, then teleport the banned local player into to the ban-zone each frame. It's just local, so any extra performance cost of teleporting 50 times a second is shouldered by the person you don't care about, and it gets around modded clients potentially being able to teleport away.

You can also set their voice far-distance to zero, so they're completely muted, even if they do manage to escape.

Of course, this system amounts to (counter?-)griefing, but there's no native world-moderation tools, so we're stuck with these double-edged swords for now.

[broken bear]

thanks for the review of that

I think instead of an area trigger I'll do a slow march down the player list periodically and set the boolean

[twilit hawk]

If the master is able to dynamically "ban" people (eg. through a menu), then it's probably most efficient to run through the player list only when the banning event fires.

Unless you're hard-coding the ban list, in which case it's more straightforward for you, and you can just check OnPlayerJoin.

[broken bear]

I may do both, a hard-coded, then a player list that a whitelisted player can bring up and interact with to ban or unban. this avoids using a collider trigger object which could go wrong

I'm still very new to udon so it will take some time to navigate this, but I do appreciate the feedback on this

[twilit hawk]

Instead of also having a whitelist, it might just be easiest to let the instance's master control banning/unbanning. That way the griefers/cheaters can simply make their own instances to be in if they want to just experience the world.

No problem!

[unborn hornet]

Actually you can. I do this for my prefabs to specify a color pallete for UIs of my assets

[void ridge]

Right, but can you have more than one active at once?

[unborn hornet]

Yes.

[edgy plume]

i dont know much about the new sdk3/udon but anyone know how can i upload my old sdk2 world to the new sdk3? i tried importing the assets folder to the new sdk 3 but i dont see my scene.

[jaunty schooner]

I've got a pickup with two children representing open and closed states. I'd like the player to click on the pickup to open and close it, and I want the current state to be synced across all players in the room including late joiners...

This is how I have it currently set up:

But I'm wondering if I should be using events for this instead, and if so, how I would do that with six different pickups without six different Udon scripts with different event names on toggle? Also, I seem to recall someone telling me that synced variables aren't synced very often, while events are instant? I can't recall exactly how long they said each takes though.

Heyo,

I'm having some trouble with a UI panel where I can interact with it in desktop mode, but I can't get the laser to appear in VR. The canvas has a VRC Ui Shape component, and is on a non-ui layer.

Anyone seen this before?

[cunning mist]

Try putting a box collider on the Canvas itself with a Z scale of like 0.01 or something, see if that helps.

[visual drift]

oh heck, I've been making heavy use of your tutorials as I fumble through this, thanks for those!

Collider doesn't seem to have any effect, still can't get a laser goin 😦

[cunning mist]

Do you have any big Colliders in the way? If you have any large trigger Colliders, they need to be on MirrorReflection in order to keep your hand from getting blocked by them.

[paper plinth]

is that why buttons don't work inside my walkable ship?
or is it that you are being teleported about 50 times per second?

[visual drift]

This was 100% it, thanks much

While I'm here, is there anyway to get a full list of players inside a collider? Or do I just have to keep track of everyone entering and exiting. Basically, I have a stage and I want players standing on it to have their voice volume increased when a button is pressed to "turn on the microphone"

[cunning mist]

Entering and exiting would be the easiest way to populate that list, though there's definitely route's both ways.

Glad the collider check worked 👍

[twin drift]

The VRC_Panorama replacement isn't available yet, right?

[fiery yoke]

There is no replacement yet.

I've mostly got this working but I think I'm running into a permissions issue with SendCustomNetworkEvent. It's getting blocked in some situations, saying "RPC abandoned" in the logs. Is there specific rules about master/ownership I should know for network events?

[full wind]

hi anyone knows what could cause this? [USharpVideo] Video failed: https://1drv.ws

Does anything see anything wrong with my code here? My magazines are behaving oddly.

So I've got some magazines in my world right? One is open, the others are closed. I could see them all until I designated them as pickups and added the script. Now all the ones that defaulted to closed are gone (presumably invisible) and the one that was open has both its open and closed states visible at the same time.

These are the parameters of the magazine that defaults to open:

So here's what I expect to be happening:

Each update, the graph runs, and sets the Open magazine mesh active state to equal MagazineOpen. Therefore, if MagazineOpen is true, the Open mesh will be visible, and if it is false, it will not. The Closed magazine mesh's active state meanwhile is set to the opposite (boolean negation) of MagazineOpen. So if MagazineOpen is true, the closed mesh will be hidden, and if it is false it will be shown.

Alongside this, the code is checking to see if the player's use button went down. (I assumed this only fires once, though now I'm wondering if it fires constantly while the button is down, though even if it did, that shouldn't be the cause of this bug since I was not holding the magazines.) If the button was clicked, then MagazineOpen is set to the opposite of what its current value is, thus toggling it true and false each time you click the object.

This all seems straightforward, and yet, my open magazine is showing both open and closed meshes, while the closed ones are apparently showing neither.

Since the only difference between theses objects is what I set the default state to... It seems like both open and closed active meshes are just being set to the default value. In other words, the boolean negation I placed before the closed mesh's active state is set to the value of MagazineOpen isn't working.

[jaunty schooner]

Hm, actually it has to be more than that, because the closed magazines default to having the closed magazine mesh visible. Which means not only is the closed mesh being made active on the open magazine... It's being made inactive on the closed magazines. While the open mesh... Well, that doesn't seem to be being touched at all. It remains hidden on the closed magazines, and remains visible on the open magazine.

Why aren't there any Udon examples for simple things like toggling a synced boolean?

I found these two examples for incrementing a counter, but they use an event, and I can't make heads or tails over what the difference between them is:

Like, I can't tell what these examples are supposed to DO. Does the first one increment the counter and sync that count to all players ONLY when the owner of the object clicks it?

And does the second one do it when anyone clicks it? And if so, why do that, since it's my understanding that as soon as you interact with an object, you own it, so only the owner should ever be able to interact with an object?

Perhaps the issue with my code above is I need to use OnDeserialization? I just found this page on that: https://ask.vrchat.com/t/how-to-send-data-over-the-network-using-synced-variables/2264

But from what I can tell my code should still work even if I don't trigger it based on those deserlization events... But it might be running more often than it needs to since the data may not have changed. And even if a deserialization event has triggered, the state still might not have changed. Though I'm not sure if its really worthwhile to add the extra complexity of an if statement to check if the data has changed rather than just setting the active state, since I can't imagine setting active repeatedly is noticablly slower than doing an if statement repeatedly.

where can i find how to use Network.GetNetworkDateTime ?

i can not find an article about networking in vrchat documentation

I think you're overcomplicating the magazine thing. I think you need to start with your pickup scripted in one way, and then change it when the player interacts with it.

[jaunty schooner]

@paper plinth "I think you need to start with your pickup scripted in one way, and then change it when the player interacts with it." - I don't understand.

I have no idea what you're trying to convey. Start with my pickup scripted in one way and then change it? It sounds like you're suggesting I swap the script on the object after the player interacts with it, but that doesn't make sense.

[paper plinth]

Your graph looks like you're trying to write your entire script at once. Your script has multiple parts that interact with each other.

[jaunty schooner]

Sure but it's a very simple script.

I'll try removing the part to allow it to toggle the magazine and see what happens.

[paper plinth]

Envision how you want your object to look when it's not being interacted with and script it that way.
Then use blocks and branches to build on top of that

If you want to write it all at the same time you need to establish how you're going to do that first.

Like...write a requirements and specifications document

Also one of the benefits of graph is being able to visualize your script that way and when you have your elements interact like you're doing, you're not really using one of the great benefits of graph and nodes.

It's cool to spread out.

[jaunty schooner]

You're making this out to be way more complicated than it is.

[paper plinth]

Different strategies of writing scripts require different levels of planning and what I'm suggesting is that if you want to keep going down the path you're on, it would be helpful to you to have at least some metacode telling you how to build it. But you're right, it's a pretty simple script.

[jaunty schooner]

So I removed the noodle that toggles the value if the user is interacting with the magazine... And now they all retain their initial state the way I expect them to?

I just deleted that one noodle on "OnPickupUseDown" that went to SetMagazineOpen.

But I'm just more confused now. That node should never have triggered. Not only because I haven't even tried to pick up the magazines, but also because I just tested this in the editor where I literally can't interact with pickups.

The graph compiles okay so it's not that the graph isn't running at all...

I'm gonna see what happens if I reverse the inputs...

Okay.. the graph is definitely running...

When I did this, all my closed magazines opened and the opened one closed. So the graph is working, aside from that one OnPickupUseDown node which caused everything to go wonky.

I'm still at a loss to explain why this isn't working though. That OnPickup node should never trigger in these tests, so it being connected or not should be irrelevant.

Futhermore, even if it were triggering repeatedly, the state the magazines are ending up in makes no sense.

Also, what even is that Start node? I cannot find any documentation for it. I only used it because I saw others using it. But I'm wondering if maybe it only runs once the first time the script executes. Cause there's also an Update node, but that too is undocumented.

[paper plinth]

Don't forget Awake

[jaunty schooner]

Awake what?

[paper plinth]

And FixedUpdate

[jaunty schooner]

Well I've heard of FixedUpdate. But I don't know what you're getting at, unless I should go look in the Unity docs for a Start function somewhere. But I'd asssumed that was just a special Udon node.

[paper plinth]

Nah
Start happens when the game starts
Any object in a scene asset that has a start event
The start event fires

If your gameobject is not active when the game starts
Awake will fire when you make it active
Never seen anyone use it

Update fires every program scan/frame

[jaunty schooner]

I just found these docs: https://docs.unity3d.com/ScriptReference/MonoBehaviour.Start.html

[paper plinth]

If you're sequencing events and you need more determinism / predictably there's fixedupdate which I don't know how to use

But your script isn't working because it fires once when the game starts and never again

You need to use update if you want your code to execute

[jaunty schooner]

Hm... Well now I wish I could recall whose script I was looking at when I saw that Start node used because I want to know why they used it.

[paper plinth]

Start os for configurations, setting the pos/rot, setting variables that do t have defaults, setting up interaction conditions...

*is

Now that's where you get to see the utility of developing your program step-by-step

[jaunty schooner]

Yeah, I understand that now. I'm not new to programming, but I'm new to scripting within Unity. And to Udon. And I have no way to tell if a node is an Udon specific thing or a Unity specific thing and I keep forgetting that sometimes they're Unity functions.

[paper plinth]

You can do anything that's exposed and almost everything you need is exposed.

Nodes are just scripts in a different visualizer

[jaunty schooner]

I've got like 30 years of programming experience, so I know how to code, I just didn't realize the start function there wasn't doing what I thought it was. I thought it was the "start" of my program flow in an udon graph.

However, even if I fix that Start issue, this still does not explain why having that OnPickup node connected breaks everything.
