udon-general

[wanton oxide]

yeah no

the same code is running in a completely different world now

[fiery yoke]

I actually have no idea how coroutines work. I think they are done in a different thread, but for Unity to execute any UnityEngine stuff it has to go back to the main thread. And I dont know how scene unloading is handled, but I would imagine that it would stop coroutines by default. But yeah thats implementation details.

[wanton oxide]

This is my own code

Running in murder 4

[fiery yoke]

Yeah lol

if you know what the methods are called in there you can make them execute

without even modifying the client kek

[fading cipher]

bruh

Well you're welcome everybody, we just found a huge security flaw

But uh, can my code work now please? xD

[fiery yoke]

Nah its mostly harmless

Worst it can do is mess with in-world Udon logic

[fading cipher]

I'd still consider that huge because it ruins the experience of my players :P

[wanton oxide]

i don't know if its a huge security flaw

but def still a problem

let me change my bug report actually to more properly describe this issue

Its worse actually

[fiery yoke]

Well Im not sure what exactly happens, but I would imagine that the VM just doesnt stop current delayed events when you change instance / unload the scene

[wanton oxide]

This proves that the udon vm stuff doesn't get cleared at all between instances

How is it running bytecode that should not even be in memory

[fiery yoke]

Would be interesting to see what happens when you go to a SDK2 world while delayed events are active

Well the Udon VM stuff is in a sepcial DontDestroyOnLoad scene

[wanton oxide]

yeah so uh

it runs in vrchat home now

srry for the crappy screenshot

but yeah there you go 🤔

[fiery yoke]

Wait a second

youre saying its not just trying to call the event

but actually running code?!

[wanton oxide]

It is executing the code

so uuuh

yeah

[fiery yoke]

Well now thats an actual issue lol

[fading cipher]

It's debugging, and it's only debugging if it's reading the code in the method

[wanton oxide]

Yeah the debug.log keeps being executed

[fading cipher]

every 20 frames, on repeat :P

[fiery yoke]

That means that you can potentially carry Udon code into any world you want. Thats a pretty bad exploit. Its still mostly harmless, but its an attack vector that you can potentially abuse if you find worse loop holes.

[wanton oxide]

yes

you can carry any udon code you want into any other world

as long as it can stay within one behaviour

you can just keep sending more sendcustomevents every frame to get an update loop going

[fiery yoke]

I actually have no idea how that happens then lol

[wanton oxide]

yeah well we have reproduced this many times now

[fiery yoke]

Even in none-Udon worlds?

[wanton oxide]

yes

it happens in sdk2 worlds too

[fiery yoke]

Yeah thats bad lol

Now I want to experiment with that 😅

[wanton oxide]

go ahead

its so bad lol

[fading cipher]

If you want to see it firsthand, I can inv you to my test world rn

[wanton oxide]

updated the bug report to actually reflect the issue

[haughty nacelle]

How can I reduce vrc crashing and freezing when I am in a world?

[dapper lion]

make things togglible. and have them disabled by default

[haughty nacelle]

Where would that be in the settings?

[dapper lion]

your world

[haughty nacelle]

My hub world?

[dapper lion]

wait, are you talking about udoning?

[haughty nacelle]

?

[dapper lion]

i think your asking about vrc in general. you should try asking in #user-support-old

[haughty nacelle]

Oh OK ty

[young swan]

Sorry if this is the wrong place, anyone have any tutorials on ai/npcs? New to udon. Wanting to make a fairly static npc that users can interact with (talking and ordering items) and can do some idle animations (walking in a small space, generating prop items). Please let me know if this is the wrong place to ask!

[torn grove]

Is there a supported quick way to append an item to the end of an array in UdonSharp?

[torn grove]

All of this works pretty much the same in UdonSharp as it would in normal unity, the stuff you would utilize like Animator.SetTrigger(...) works in UdonSharp

So basically any unity tutorial on the topic of animating an NPC, using an Animator controller, firing Triggers for animations, etc, works the same as usual as any game you'd make in unity

[floral dove]

I think you'll need to make a new array with a larger size, copy the contents over, then update the last item, just like in C#. If there's a special UdonSharp shortcut to do this, maybe someone on the UdonSharp Discord would know better than someone here.

[fading cipher]

Has there been any news or any talk about VRChat giving creators more custom layers to work with?

[grand temple]

that's kind of a fundamental unity limitation, not sure what vrchat can do

unless unity 2019 has anything?

[fading cipher]

Ah, well TIL, thanks lol

I think I can be smarter with my layer stuff to reduce my customs. I definitely have enough room currently but I’m not sure what future layers I may have to implement and given how many I’ve already used, it’s fearful 😧

[grand temple]

try to avoid using layers just for stuff that will be a trigger collider. There's no need to do that as you can instead just detect something like the name of the object if you want something to happen when it touches something

Layers are only really necessary if you need to use the collision matrix for actual collisions, not triggers

[cunning mist]

Layer collision was absolutely essential in SDK2, so I fully understand why we see a lot of people overusing the layers for more complex Udon stuff. I really need to do an object detection video here soon.

I'm planning to do a new video every two weeks, someone hold me to that.

[torn grove]

In UdonSharp, is there a way I can get the sender/trigger or pass args or something into custom events I trigger? I want to wire up multiple UI Buttons to the same event, and do logic based on properties of which button triggered the event.

Is there a way to do this without having to make a custom distinct event for each button?

[grand temple]

The way I like to do it is to have a text component sitting somewhere disabled. The UI button sets that text component's text, then sends an event to the udonbehaviour. The udonbehaviour reads the contents of the text and parses it out into whatever I want to do

[torn grove]

I could theoretically set the button to be inactive or something like that to make it distinct first, then fire off the event and snag the button that is different from the rest yeh?

[grand temple]

that might work. That would require the udonbehaviour to scan every button though

[torn grove]

Youd have to do that with any other approach no?

[grand temple]

no, the strategy of setting a text component only requires the udonbehaviour to look for that one text

then after that it's basically just passing a string as an argument

[torn grove]

Right but then scan each of the buttons via some manner to identify it based on that text

[grand temple]

no

[torn grove]

Like I still need to get the button that was clicked

The property I specifically need is the buttons transform position

[grand temple]

oh, well then sure in that specific case I suppose

[torn grove]

So no matter what I have to loop through all the buttons (and short circuit out when I find the right one)

[grand temple]

technically you could use the string to pass in a vector3 but that would be inefficient

[torn grove]

Id need to fetch the vector 3, is there a way I can "copy" out the real time x and/or y position of the button as a variable?

[grand temple]

if you specifically need some property of the button itself, yes I think your plan of disabling the button then scanning all the buttons for the disabled one would work great

you'd have to make an editor script to do that

[torn grove]

Like what I basically need is simply this, but as a prefab so its automatic as I paste copies of it, each one just uses its value

Is there not a way to be like "Use my transform as a passed in var to something else" in Unity?

[grand temple]

not really

[torn grove]

Cause then I could just set the x/y values to be the x/y values of an empty dummy game object

Or even just the entire transform as a whole

Bleh, yeah I guess Ill just need to basically enable a dummy component on the button

[grand temple]

you can use events to set variables on scripts, but the problem is that when you make a variable on an udonbehaviour it's not a real variable on the monobehaviour so the unity event system doesn't know what to do with it. You could use setprogramvariable but that requires 2 arguments: the name of the variable and then the value. But unity events only support sending events with one argument

[torn grove]

Is there an "empty" component I can put on game objects? What is the best way to be like "This is a dummy component that doesnt actually do anything"

[grand temple]

just disable the button itself, you had the right idea

that shouldn't interrupt the flow of the event and that includes re-enabling the component after

[torn grove]

Aight, Ill have to try that out

basically the button when clicked teleports the player, its on a map UI, and Ive scaled the map logic to be at a ratio to the actual world. So theoretically the x/y pos of the buttons I put on the map can inherently reference a real world x/z position. So rather than manually programming "this button teleports them there" I can just slap the button on the map and its x/y pos on the map... automatically logics out to where it teleports em to

Also lets me have a nice little map icon for where the player is on the map, and where they are facing

Basically waypoints to fast travel around the map is the goal.

[grand temple]

that's a great idea

[torn grove]

You can see bottom left of the map there the player icon. My maps are extremely large so, having fast travel and an actual map is pretty necessary. It takes awhile to get around haha

Im nearly done uploading them all and can move onto the next phase, putting the portals down all over them to link them together.

Then I can just focus on detailing each map 1 at a time, they all need a lot of fixing up and had some bugs on their export, and I wanna dig deeper into adding better ambience. Rain to some worlds, mist on others, perhaps some particle wind/leaves/dust effects, stuff like that.

[mighty fjord]

How about creating an udon behaviour for the buttons which contain a reference to the main behaviour and the buttons ID, which would then be used to determine its position in someonething like an array?

[oblique crypt]

Thanks so much for sharing this. I've tried doing this with autoplay on and using a timer to setActive the gameobject with the video player script on, but it doesn't work. Do you think I need to turn autoplay off and use "loadURL" and "play URL"? Or just "play"/or just PLayUrl, since the URL is already entered in the inspector? Also I used start rather than OnPlayerJoined, which did you use? I'm not sure if Start will work for new players, but worried OnPlayerJoined will reset the video player every time someone joins...

ignore "target object on (change to off)", has been changed to off, was from following tutorial that did opposite

or does anyone else see a problem here?

[cunning mist]

I hate this
It's beautiful

[fading cipher]

gonna shift this to #world-development

[scarlet lake]

ok I am absolutely hitting a wall with trying to sync a variable. I got a world where you press a button and it activates an object and deactivates the rest. pressing the button increases the "index" variable. if someone presses it locally it increments but a late joiner doesn't get the same number and they end up de synced even after pressing the button. Any help?

[torn grove]

You need to hook into the on player joined event and re-broadcast the variable no?

Query: Is there any way to tweak the physics for the maximum threshold of a slope players can run up? My imported worlds heavily rely on players only being able to traverse up a moderately shallow incline, but VRChats physics engine allows a much steeper incline. Is there a quick and easy way to lower the threshold of an incline a player can get up?

[dire trellis]

Hey guys, I'm having a problem with my world atm.

It works great whenever I create an instance of the world on VRChat, but as soon as another player joins, the "owner/host" of the world starts lagging super hard (10-20 fps).
More players can join and it works fine for everyone except for the world "owner/host".
However, if the owner/host leaves, I'm guessing the world ownership gets transferred to the player who joined first, because the lag then gets transferred to that player.

Any of you know what could be happening here?

[torn grove]

Do you have scripts running that interact with the host?

[dire trellis]

What could be an example of that?

[torn grove]

A script? Well you wouldve placed the script and made it I presume

[dire trellis]

No interacting with the host

Yeah I have scripts running haha

[torn grove]

Well any code you have that specifically finds the host player and only does stuff if it is the host

[dire trellis]

Hmm I don't think so

[torn grove]

IE:

If (!player.isHost)
   return;
// Now a bunch of logic down here that only runs for the host

[dire trellis]

I'll double check my scripts to see, but I don't think I have any of that

[torn grove]

That or any loops or something you have that may actually only be running for the host

[dire trellis]

Does is mean anything that this only happens if there are multiple players in the world?

[torn grove]

I would start by disabling all your scripts, see if that fixes it. If it does you know its one of the scripts running wild eating up processing power

[dire trellis]

Example, I can run the world just fine until someone joins

[torn grove]

They dont lag if alone in the world?

[dire trellis]

Nope

[torn grove]

Do you do stuff based on like, on join or on leave events?

and do you broadcast item positions, variables, etc?

Id start by disabling all scripts, see if lag goes away

[dire trellis]

Shouldnt be any on join/leave events

Yeah I think thats a good idea

[torn grove]

For the record you can test locally via Build and Test and just set clients to 2

[dire trellis]

Yeah I figured that out recently haha!

But thanks!

[torn grove]

Then just enable your scripts one at a time til suddenly it starts lagging

That will quickly isolate the problem script that likely has something funky its doing thats messing with stuff. Likely some kind of loop or whatever thats failing to complete and is just looping infinitely

[dire trellis]

Yeah I'll give that a try, luckily I dont have that many scripts

[unreal grail]

Question for you. Does the VRC Pickup component currentLocalPlayer return the VRCPlayerApi of the person holding the pickup, or the owner of the pickup?

(in the event that those are not the same)

[torn grove]

It returns the local player I believe, the player that is the active real player, vs all the other players which are other folks networked in

basically "Local Player" is <player who is controlled by the actual person running this instance on the local client>

[torn grove]

@grand temple It worked! Teleporting automatically via the placed buttons position is functional and pretty accurate :3

[grand temple]

nice!

[torn grove]

I decided to also put some letters on the teleports to make it easier for players to communicate

Im pretty happy with how it looks in game, the buttons are kinda small but can still be hit reliably

[dark gale]

Is there a way to change jump strength with a button in udon? Any scripts/resources out there?

[floral dove]

the VRCWorld prefab shows how to set jump strength on Start. You can look at this to see the nodes that control strength, and instead use a UIButton or Interactable item to change the strength.

If you want to learn the basics of triggering things in Udon using UI, you can read about some of the UI examples from the UdonExampleScene here: https://docs.vrchat.com/v2021.2.2/docs/udon-example-scene#udon-variable-sync

[unreal grail]

Trying to find out: does VRC_Pickup isHeld node return true if anyone is holding it, or only if the localplayer is holding it?

[shut kelp]

i have a question. is vr chat just not working for any one else? When I try to make special effects or move my triggers or fingers, it just stay still. please help

[grand temple]

Sounds like you have gestures disabled. You can toggle that in the action menu

[shut kelp]

Thank you, I was really puzzling over the problem.

[solid sluice]

Someone knows unity Shader coding? i want to change a _Color to a texture and change the color of the shader like that

[cold raft]

i never did shader coding, something i still want to learn someday but nowdays if i want something special i just get poiyomi shader it does pretty much anything id want

[scarlet lake]

@solid sluice maybe this can be helpful? https://docs.unity3d.com/Manual/SL-VertexFragmentShaderExamples.html

[solid sluice]

i was checking it and i see that they use _MainTex for the color

but my thing has 2 textures, 1 for the color, 2 for the actual texture

maybe i can something like joining 2 textures on coding...

[acoustic vale]

Would "custom packages" be the right thing I should use to make reusable Udon components? https://docs.unity3d.com/Manual/CustomPackages.html

[scarlet lake]

@solid sluice if you never have written a shader in Unity, try make a small shader as a proof of concept. It is probably easier than trying to figure out an entire shader and alter the code ^^

and then you just add the bits from the other shader you liked and slowly build it up to the thing you want. When it works you can just replace the other shader with the code you wrote if needed

[solid sluice]

i have the actual thing working with one texture but not with 2

it's a prefab of a fog

i want to change the _Color

[scarlet lake]

I am at work so can't write & test things myself right now, but maybe this can show you how to use multiple textures: https://answers.unity.com/questions/1325494/how-to-make-a-shader-with-multiple-textures-and-an.html

[oblique crypt]

Does anyone know how I can set an object as hidden (but still active) by default? I need to have a videoplayer UI hidden by default (while the video loads on start), and I have this basic toggle button, but if I disable it in the inspector, then when it toggles on, the duration counter isn't synced to the video, as it needs to load at the same time as the video player (start).

[void ridge]

You could separate the program that you want to be running (the one with the counter) onto a different empty object and leave that active

[torn grove]

Anyone know if theres an Udon supported way I can approach needing what amounts to a Dictionary<AudioSource, Texture[]> passed into my script in some way?

The goal is to achieve dynamic footprint sound effects that play as the player walks around, based on the texture of the ground they run on. Each of my worlds has a variable amount of footprint sounds supported, and each footprint sound would have a different list of textures mapped to it.

Then during runtime all I have to do is periodically (Im thinking once a second) raytrace from head straight down (environment only bitmask'd), take first hit mesh, get that mesh's texture, then look it up against the list of meshes and find the mapped audio source, and then enable/disable the associated one and disable the rest.

Then I will have a seperate script actually handling playing the footprint sound effects, scaling it to player move speed (so it only plays when they walk around)

So thoughts on how to actually pass this data into my prefab? Is there a way I can make a subscript that has an AudioSource serialized field + a Texture[] serialized field, and then I can attach n of those scripts to the parent object, and that forms my "dictionary"?

[grand temple]

There is no way to have that as an actual data type, but if all you want is a nice inspector that displays two arrays together as one, you can use UdonToolkit

[torn grove]

I need a dictionary, not two arrays, ideally

[grand temple]

an actual dictionary is not an option

[torn grove]

Its a one to many relation, effectively

Can I achieve this by having multiple scripts? Like can udon fetch fields from another script?

[grand temple]

you can have an array coupled with a jagged array

but you'd have to make your own custom inspector for that

yes you can do it with multiple scripts but I think that's a dead end that would be more work than it's worth

[torn grove]

IE:

WalkBehavior script

• WalkEntry[] Entries

WalkEntry script

• AudioSource Audio
• Texture[] Textures
• bool IsDefault

I can have these built all as prefabs and just drag and drop em on

My main thing is I am just trying to avoid loading all of the footprint audio and scripts for them for every map, some maps might only use 2/14 of them

So to kind of optimize, trying to figure out a way to easily have a prefab I can just drag and drop "these are the supported ones for this map", I can have a library of WalkEntries I drag and drop onto the maps WalkBehavior to "enable" them

[grand temple]

yeah that's a noble goal. It certainly could work but that's not how I'd do it

just remember that with U# you can make completely custom inspectors. In editor, out of play mode, it is running a "proxy" that has real C# code. That C# code can access real custom classes, run real unity guilayout code, everything

[torn grove]

The main thing is trying to avoid the gotcha of needing two seperate arrays to happen to have the same length. Two seperate arrays would put me into having to rely on a runtime error, whereas a dictionary logically cant have that problem

Im not sure what a "custom inspector" is

[grand temple]

https://github.com/MerlinVR/UdonSharp/wiki/Editor-Scripting

https://docs.unity3d.com/Manual/editor-CustomEditors.html

You can make an inspector that always ties your two arrays together so they are the exact same length no matter what

[torn grove]

Ah sick so, I could implement the dictionary logic in the custom editor, then convert that into arrays (that I can rely on being same length) in the actual udon code?

[grand temple]

exactly

[torn grove]

That probably will have an even smaller footprint, I imagine loading all those values out of those scripts would have a fair bit of overhead, vs baking the values directly in via editor

Perfect, that should get the job done, thanks!

Do you know offhand of a good "Dictionary<T1, T2[]>" custom editor scripts by chance?

[grand temple]

not really, but theoretically if you find a good one for base unity you can steal 95% of it

[torn grove]

And the custom editor code I can just use vanilla C# code, converting from Dictionary<T1, T2[]> to a T1[] + T2[][] Is pretty easy I think

What I like about the Texture[][] approach is I can pretty easily do a breadth first search rather than depth first, I think? That way rather than "try all textures for sound 1, then sound 2, then sound 3..." I can instead do "Check all of entry 1s for each sound, then entry 2s (if they exist), then third, then fourth..."

Letting me imply that the first texture for each sound is the more common one, basically Id want to order the more commonly occuring textures first, and put the rarest least likely ones last on the list.

[clever olive]

So, does every gameobject/rigidbody have an owner? Or does it only apply to synced physics objects/udon behaviors?

I have a rigidbody with some joints attached to it, and i was wondering if i'd need to set the owner of every rigid body in order for something like "Allow Ownership Transfer on Collision" to work (with the beta).

[fiery yoke]

It only applies to objects with a NetworkView. Which are generally all objects that send synced data over the network.

[clever olive]

So I assume the joints on a non-synced rigidbody (attached to a synced rigidbody) wouldn't have an owner then

[fiery yoke]

Yes. Well. Technically every object has an owner. Which by default is the instance master. But thats a technicallity.

[clever olive]

Would the fact that everything has an owner affect "Allow Ownership Transfer on Collision"?

[fiery yoke]

I dont think so. But Im not 100% sure. That feature has been broken for a while

[clever olive]

I guess that's more of a beta question.

Well, I assume it doesn't hurt to just set the owner of those joints. Might as well give it a go.

[fiery yoke]

Im not even sure if setting owner would work at all like you want it to.

That feature is exclusively meant for synced objects I think. Anything else might cause weird behaviour.

But give it a try...I guess

[clever olive]

I was having issues with that feature just straight up not working in the beta with this car I'm making.

But the wheels for it, which are attached by joints, are at the front/back of the car. If the car is colliding with anything, I'd assume most of the time itll be the wheels.

I just wonder if setting the owner of the wheels would make the functionality work properly. I'll do some testing in the beta.

Doesn't seem to make a difference. Oh well.

[oblique crypt]

Thanks very much for the suggestion, I'm not sure if I can though, cause it's an Udon# video player and it needs a quite specific configuration I think. I'll see if I can though, thanks. I wish there were a hide function or something...

[void ridge]

You can always disable the specific components that you don't want people to be interacting with

if it's a UI canvas, you can disable the collider that catches the UI laser

other than that, you can always disable whatever renderer you have that's rendering the thing. for a UI canvas I assume disabling the Canvas Renderer component temporarily would do that

[torn grove]

Can you just physically hide it? Slide it backwards behind the wall, or down through the floor, and mute it?

What do you need specifically disabled? Do you just need it to be hidden from player sight while you load it up, and then when they trigger something the video player gets shown (but outright setting its active flag to false wont work cause it kills scripts?"

Im pretty sure you can specifically disable the renderer itself to make it invisible, and the collider to make it so it cant be clicked, without interfering with the rest of the stuff (so its still technically there, it just cannot be seen or touched)

[sharp briar]

I'm using an udon behaviour that resets pickups and one that turns the pickups game object off at the same time on use and only the turning off seems to work

[sharp briar]

objects that are sync toggled off dont move while turned off so

i need the toggle to happen a moment after the reset i guess?

[floral dove]

I highly recommend reading through the new Networking docs to learn how things work in the Udon Networking Update!
https://docs.vrchat.com/docs/udon-networking

[floral dove]

^not directed at anyone in particular, just wanted to say it so I could pin it

[sharp briar]

does this mean you dont need to add empty udon behaviours anymore when youre making normal pickups?

[grand temple]

correct, instead you can add an objectsync component

[sharp briar]

cool

[shut patrol]

Is there a byte array sync overhead? (for example, not synchronizing directly, but by converting to another type)

[torn grove]

For those of us depending on UdonSharp, do we have to wait for an update from UdonSharp before our worlds built with older version of it to work with the new update?

[paper gate]

v0.19.10 is compatible

[torn grove]

Coolio

So just need to update my SDK?

[paper gate]

yeah

[civic shard]

i cant join my friends and it says there's no updates

why

[floral dove]

we just pushed an update, try restarting steam. Also FYI - #user-support-old is for general questions, this channel is for questions about Udon

[civic shard]

ok sorry

and i have multiple times

[torn grove]

Whats the best avenue by which to poke VRChat devs for feature requests in a casual way, like, "Do yall have any future plans for <feature>?"

A big feature I would love to see is a way to pass off data in some capacity through world portals, even something as simple as just a single int you can utilize or whatever, and then a world designer can then add logic to consume the passed in variable if they care (So something simple like being able to specify which spawnpoint to use when the user uses the portal, or a way to say "they came from here")

Would be extremely handy in my case for my project which spans many worlds linked together by portals, would be cool to implicitly "know" where the user came from via the opted in value or something when they arrive in a given world

Right now my solution is just uploading a copy of the world for each "entrance" into the world, and thats how I pass the data along. But if there was something simple like an int I could just pass "into" the portal, it would not only reduce the amount of stuff I have to upload to the server down to like 1/4, but also reduce my effort and workload to like 1/4 haha

Also a bit of an awkward bug in that the VRC world SDK is counting World descriptor scripts on disabled objects for uploading, so if I have 4 descriptors, but 3 of them disabled, it still complains about how there should only be 1 of them. Would be nice if it only counted ones on Enabled objects. Right now my workaround is I have to not only disable the object, but delete the script temporarily off it (then revert the delete when I want to enable it), which works fine but its just a bit of an annoying bug to work around haha

[floral dove]

We read through all feedback on Canny: https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback

[torn grove]

Thanks! Ill post it over there

Oh sick theres literally a post on there right now requesting this sort of feature too, well alright then Ill add my 2 cents to that!

[broken bear]

If I wanted to change a Detail Density of a Terrain, is that possible in graph (or even U#?) I can't seem to get it to recognize a terrain component. I guess I can just stick to an animator

[broken bear]

hmm I can animate it the value and it shows in the inspector, but the detail doesn't update. it does if I manually touch it in the inspector, interesting. Just running a simple animator 0 to 1. I guess the inspector is calling a terrain update ? This is all in unity, I'll test in vrc. Edit: Well doesn't update in vrc. not sure how to change the Detail Density of a terrain in runtime then hmm

[cunning mist]

Terrain settings are for generating the terrain, once terrain is generated there's no editing the settings in a build, as far as I understand.

[chilly crater]

Did I approach this right for spawning and assigning ownership from objectpool on player join and return on playerleft?

Or would I be better off having the return in the script of the object itself. IF OnPlayerLeft = Owner : return to objectpool

[karmic ingot]

Is anyone else Object sync not working in the new SDK? (I have tested in 2 worlds)

I have added the new Object Sync, but when in game it is not syncing with other players. Am I missing a step?

[tranquil summit]

so i tried to figure it out for myself but i just don't know enough about udon right now- how would i got about syncing an animation of something that just constantly plays in the bkg (in this case a train that continuously rolls by)?

[cunning mist]

Since the update is still quite new, are you sure they had the most recent build of VRC?

[karmic ingot]

I downloaded it from the vrchat site once the announcement went live, I guess I may have done it to soon 🤔 I will take a look again! Thanks!

Version: VRCSDK3-WORLD-2021.05.17.12.52_Public

[cunning mist]

Sorry, I meant to ask if they were on the same game version, meaning they had the most recent one on Steam.

[karmic ingot]

Oh, Yeah my Vrchat is updating now, Looks like I got to excited for the update and missed one of the most important steps!

Thanks haha

[grand temple]

if you want to make sure you get the update in the future you can always restart steam and it will kick it into gear

[karmic ingot]

Yeah I was running Vrchat through the Unity test mode, so I had not logged into Steam yet. but its downloading now! 😄

[last swift]

so I have a wall setup with an animation that makes it come up out of the floor with a tv on it and so far the code I have seems to work as far as getting the animation to play but the wall never comes up out of the floor. anyone know what could be the issue?

[grand temple]

animator.play is probably not what you're looking for. I would recommend instead making a trigger parameter on the animator, using that trigger as a condition in the transition, and then calling animator.SetTrigger when you want it to happen

oh wait sorry you already have a bool, that can work too. But are you sure you're using it right in the animator?

[last swift]

honestly I'm not sure but it stays in the start state waiting for the bool to be true and when it does turn true the animation should play

[grand temple]

can you take a picture of the transition settings?

[last swift]

this is the transition between start state and tvHolderUp

[grand temple]

for anything that has a dynamic condition you probably want "has exit time" false

does this work if you enable the bool in play mode

in editor

[last swift]

it transitions to the tvHolderUp state but the wall doesn't come up

[grand temple]

so the animator is all good, are you sure the animation is correct?

[last swift]

when I play the animation in the animation window it seems to work fine. I see the wall come up and then it just loops over and over

[grand temple]

is the wall set to static in the very top right?

might also be the wrong path

[last swift]

no it's not set to static. and what do you mean by wrong path?

[grand temple]

if you select the animator's gameobject and then go to the animation tab, then in the dropdown there select the tvholderup from the dropdown, do you see yellow text?

[twin drift]

A replacement for VRC Panorama was discussed during the last stream right? Or am I crazy

[last swift]

I don't see any yellow text but I'm kind of confused on what you mean. here is the wall working in the animation tab

[last swift]

i don't have any colliders on the wall but it seems like maybe when I put it under the floor it messes it up or something. I tried doing the same thing with a cube and it worked. Then I put the cube under the floor and it still worked so I used that as the wall instead and then it stopped working again

[torn grove]

Jesus this project got pretty big pretty fast lol. Glad Im finally done the long boring part and can focus on the more fun part of it now

[last swift]

So my issue was when I added my script to the wall with the Animator it would change a setting in the Animator to receive Root Motion from the script and the script didn't have anything but a way to transition between animation states. So I put the script on an empty game object and used that to control animation changes. so then the Animator component on the wall had a field for "Apply Root Motion" that I left off and that is what fixed it for me

[proud scroll]

yo im from neos with knowledge for coding and world building, is there something like give me a pulse on true/false or change in udon? as well as a way to multiplex multiple audio objects and have them run by a single index ?

[floral dove]

Welcome, Gabriel! You can learn about how Udon works starting here: https://docs.vrchat.com/docs/what-is-udon

[proud scroll]

thank you but that doesent do anything for me since it doesent tell me what i asked, i asked if specific nodes exist like a give me a pulse on true or false as well as arraying something like audio clips

[floral dove]

Yes, you can do all those things once you understand how Udon works. If you have coding experience, you might like to try UdonSharp, which uses a C# style syntax.

[proud scroll]

dont tell me that it is possible, tell me how theese things are called or how i do them since that is what im asking, and i do have coding experience but not in c# only in c++

thats why im trying to use the graph

[coarse parrot]

The specific node you asked for doesn't exist. That's why you need to construct it yourself using knowledge on how udon work.

[floral dove]

You can use the AudioClip[].get node

[coarse parrot]

Oh I mean the one that gives you pulsing true/false

[proud scroll]

ok i see, udon is kinda useless then for what i wanna do, time to learn c# then

[coarse parrot]

It's mostly based on C# for unity. If you learned about unity you will get to understand udon very quick

[proud scroll]

yea, not gonna meddle with udon, seems to much like ooga booga, might as well code it myself from scratch then

could also be that im waay to used to neos LogiX coding but eh fuck it

[coarse parrot]

You still need udon in order to do scripting in vrc. But that's a matter of your choice of using udon graph, or udon sharp to do the scripting.

Or if you like it hardcore, do it in udon assembly.

[unborn hornet]

(Official tools)
Udon = protected VM layer between VRC/Unity and user code
UdonAssembly = low-level language for laying out logic flow and managing variable data
UdonGraph = Visual "noodle" style scripting for designing logic flow with a node graph, compiles into UdonAssembly
(Community tools)
UdonSharp = C# style scripting for writing logic in a more programmatic way, compiles into UdonAssembly
CyanTriggers (currently in closed beta) = An SDK2-style scripting for composing logic in a way that is more familiar to those coming from SDK2 (though it's not a 1 to 1), compiles into UdonAssembly

Basically everything has to compile down into UASM, then UASM interacts with the Udon VM in the game. Normal monobehaviors that aren't whitelisted by the UdonVM are completely disallowed and won't work.

There are a couple other ones out there for different languages, but I'm not sure if they are actively maintained or used.

[oblique crypt]

Any idea why my reflections are only working in Unity? They sort of work in the editor and in Game Mode, but not in VRC? The reflection probe covers the whole area, and is enabled in the object, but even though the mask is set to everything, in the Editor and Game Mode, all I see is the AO, and none of the plants or anything else. Baked and realtime. Also nothing else seems to reflect in even Unity, like the glass itself is completely invisible, and metals don't seem to shine. When I put metallic up to max on the glass, I only see a too close reflection with no plants, and moving the probe changes nothing.

[oblique crypt]

Ok so if I bump up the intensity I can see the AO reflections but they're all broken up and specular in little clumps. If I turn up the intensity any more I'm just going to get reflections that are too bright. They are about the right strength here, only all blotchy and only for the AO objects. Even at max resolution, it's still really crap.

[floral dove]

This channel is for discussing Udon, you might try #world-development or #world-lighting for your reflection and lighting issues.

[oblique crypt]

Ooops sorry, I didn't realise. Thanks for letting me know 🙂

[scarlet lake]

Is anyone familiar on how to use object pooling with Udon#?

[floral dove]

The Object Pool docs are here, just call the TryToSpawn and Return functions on VRCObjectPool: https://docs.vrchat.com/docs/network-components#vrc-object-pool

[scarlet lake]

Do people use C# to make things in Udon?

[tranquil summit]

you can

[dapper lion]

people use “udon#” to make things work on udon

[scarlet lake]

What is Udon# compared to C#? Are they very different?

[dapper lion]

um. well you have less things exposed like statics and i think certain arrays also dont work

but in practice. it is basically a more locked down version of c#

[scarlet lake]

Ahh, I see
Thank you QwQ

[static root]

does the vrchat team plan on fixing the massive udon vulnerability with the newest udon update?

since the update to udon floor colliders are removable by users with a certain client, they can change peoples avatars again, spam respawn users, etc.

[opal dew]

Um.. that sounds like a modded client issue, not an udon issue

[static root]

well the newest update to udon by vrchat opened up a number of vulnerabilities to be manipulated

prior to the update there were purchasable scripts to counter udon manipulation, all which have been made useless since the new update

[dapper lion]

thats been an issue forever and isnt technically an udon issue unless theyre somehow editing udon behaviours in realtime

[opal dew]

(also, seems kind of scummy to charge people for protective scripts...)

[dapper lion]

id like to say that udon manipulation would be a weird thing to advertise since... well.... you wouldnt need to to do stupid things like collider switches

[static root]

most of the protective scripts are decently straight forward C# coding and should be implemented by vrchat it's self to prevent or help counter these issues

imo at least

[opal dew]

I mean, have you raised any issues you've found formally on the bug report thing?

[dapper lion]

an exploit like that wouldve worked on both sdk2 and 3

[static root]

i've created more vrchat tickets then i know what to do with
most of the responses are just a professional version of 🤷‍♂️

[static root]

from my understanding it doesn't work on SDK 2
there aren't the same type of networking or scripts to call on via a client

[opal dew]

They have been quite a small team in the past and it can take time to get through everything.

[static root]

i can understand that to an extent, but i also know that it's not that difficult to counter it

get ahold of the client people keep using to manipulate udon with, create a test world implementing the new updates, attempt to manipulate the test and patch the problems you encounter

i mean most base level C# scripters have taken to places like booth or github and selling their own versions of counters, surprisingly effective counters for being entry level coders

[broken bear]

Sad if those countermeasures don’t work even on an un-updated world with legacy networking. Is this instead the delayed event issue?

[static root]

i don't even know anymore tbh
my question was if there were any intentions of attempting to patch this in the coming future

[opal dew]

I thought the whole point of Udon was that it was to prevent regular scripts from running / being included at all

[broken bear]

Or the pickup floating point issue

[opal dew]

I figured anything containing something that wasn't one of the few white-listed scripts would be automatically stripped out or blocked

[static root]

it's the networking which makes them accessible via a client and manipulable

[broken bear]

Bandit can we dm a sec?

[static root]

for sure

the floor colliders always been there, the client just deactivates it

[tranquil summit]

sorry to drop this question again, but does anyone know how to sync animations in UNU? im trying to sync an animation that plays in the world constantly (a train that passes by in the bkg) and don't really understand how i should go about it. i know i should sync the animation time, but im a bit over my head tbh

[opal dew]

I've not done something like this myself yet, but if I did I feel it wouldn't need anything new to do it. I'd go with something like, have a management object that records the initial boot time for the world by the first visitor. When a new player joins, they query the value of the first boot time and use that to calculate the time since the start and use it to work out the frame the animation should be on.

So if your animation is 1 minute (60f time units) long, and a player joins 10:30 (630f time units) later. 630f / 60f. Remainder of 30f. Set animation start frame to 30 and play.

I've possibly missed something obvious here and there's probably lots more maths involved.

[tranquil summit]

i... think this may be too beyond what im capable of at the moment lmfao
i appreciate the help regardless though

probably should've stated that im basically brand new to udon

[opal dew]

Do you have much programming familiarity outside of Udon? 😅

My day job is (web) dev code so... one kind of programming is a lot like other stuff...

[tranquil summit]

i dabble in it, but im more of a modeler than a coder lmao

[drifting sage]

Here, have some copypasta I've been holding onto for a while: If you have an exploit you wish to report to VRChat, please do so to our Moderation ticket inbox at http://help.vrchat.com/hc/en-us/requests/new. We take all exploit, security, and similar reports via that inbox. Prepend your subject line with the phrase "Exploit Report".

Assuming that the exploit has not been used by you in a harmful manner and that you are respecting our Terms of Service, moderations are not issued for exploit reports.

Your report should include:

• A meaningful and descriptive title that immediately gives an idea of what it is that you are reporting and its potential criticality
• A short summary that includes any additional details that you weren't able to include in the title
• Clear steps to reproduce, including any example code required
• A proof of concept, which might be video/image "proof" of the vulnerability, crafted URLs, scripts, files, code, etc
• Impact and attack scenarios describing a plausible manner of how the vulnerability would be exploited
• Recommend possible mitigations, if you can (if you have a very good understanding of the exploit at hand)

We take information regarding security seriously, and investigate reports when we receive them. That being said, we do not guarantee a response other than the automated "ticket received" notification.

That being said, I haven't seen any valid, credible, reproducible reports along the lines of what you're stating yet, so

[opal dew]

@tranquil summit There might be easier or pre-made scripts out there to help with animation syncing to help you get started.

[tranquil summit]

yeah, i might just be better off looking for people who've stubbed their toes before me lmao

thank you though

[static root]

then your welcome to send me a message, i have a video for you ready to go with usernames

[drifting sage]

I cut off the first part of the copypasta: we don't take exploit reports via Discord. Please send it per the instructions in the message. :S

[static root]

or i'll make my 900th ticket, as i'm assuming that's what your typing

yupppp

[drifting sage]

What email did you send them from? I can check to ensure they're being received. You can DM me the address.

[opal dew]

@tranquil summit Its something I certainly want for some places I hope to make. If I do I'll see if I can have it added to the big VRChat Prefabs list.

That's here BTW if you're looking for useful tools and widgets: https://vrcprefabs.com/

[tranquil summit]

that'd be super awesome man, as much as i'd love to just power through and learn udon to solve this, my main issue is i always kinda feel totally lost on how to even start writing codes. at least with udon there's the visual flow aspect to help out, i just don't know how/when to use things 😛

[opal dew]

I'm yet to actually get any custom animation stuff that wasn't just like, moving water textures and clouds and wind in my builds so far. Which surprisingly can get you pretty far without anyone noticing there isn't anything 'hand made'... 😅

[tranquil summit]

probably yeah, the most udon i've really had to touch so far was to sync whether or not you can use teleporters, but i should've known better than to take on such a large project as my first world lmao
not to say i shouldn'tve, but obviously there's just so much to learn

if i hadn't made that dumb train lmao

[opal dew]

Hey, everyone likes riding trains. :D I'll try and remember to ping you if I work something out.

[tranquil summit]

yeah, thanks man

[floral dove]

just FYI for anyone else reading through - there has been no specific update to Udon floor colliders, and we haven't received any credible reports of new vulnerabilities in this release.

[static root]

your about to, creating the ticket now.

[dapper lion]

technically the collider issue was a thing forever now. i think what happened was whatever source people were getting that exploiter from became more popular/public

[broken bear]

Yhea don’t want to talk specifics in an open channel, the reporting route has been given

[fallen chasm]

don't suppose it's possible to re-arrange public variables in an udon graph?

[scarlet lake]

Could I mixed Udon noodles and Ramen noodles. I was talking to my friend about it and he said it was a disgrace. I’ve tried it and the different noodles have a nice feel goin in your mouth. Thoughts?

[floral dove]

No, this is not something we have UI for at the moment. The variables are presented in the order they were created.

[last geyser]

I got a question, With the new version of Udon, How do you make something not sync for everybody, Before it had the option to uncheck it from syncing with everybody but now the only options I see is Continuous and Manuel, I was looking for something Local

[floral dove]

Objects in a world are local by default. Those options are just for how sync will work for variables within your Udon program.
https://docs.vrchat.com/docs/udon-networking#ownership

[torn grove]

So I am still having issues with getting the hitbox for my canvas to work right. Is the fact its tilted potentially whats up? (One sec Ill post pics of my configuration inside of unity)

At the moment across the entire surface of the canvas, the hit point for raycasting seems to float several inches off of the surface

Ive manually defined a Box Collider that hugs the surface of the canvas extremely tight. This also has been done with the second canvas object, MapCanvas

The MapCanvas can be enabled/disabled. To note, the distance the MapCanvas floats in front of the MenuCanvas is I would estimate about 1/20th the distance of the invisible hitbox that seems to be generated overtop

Ah okay so, I swore I modified my Z values to be lower but somehow they got set back to 1. Setting them to 0.01 fixed it

Is Box Collider the wrong collider to use to prevent an auto generated one?

[floral dove]

No, a box collider will do the trick. Yep - the issue is to make sure the z scale matches the x and y.

Otherwise you're ray casting to a much thicker box.

[torn grove]

Ah I see whats up, so that object is a prefab and I had the values set correct on the prefab but I guess they didnt propogate up to the main object for some reason. I think I forgot to save it or something

Went and re-edited it and now its propogated to all the scene objects

Is there a more user friendly way someone has made to teleport players without just instantly just... changing their position? Like a Fade In / Fade Out logic or something?

Its my understanding that straight up teleporting them without doing a fade in/out can be quite disorienting for some folks and can induce motion sickness right?

[floral dove]

Certainly, you can write some logic to fade out their view, teleport and then fade the view back in. I've done this before with an animated canvas.

However, that's mostly for aesthetics. A direct teleport doesn't often induce sim sickness, that's more commonly caused by movement that includes a player's peripheral vision and is not directly connected to their own movement.

[torn grove]

Interesting, Ill have to keep it in mind and ask for feedback from players using the teleport system, on how they feel it is

[floral dove]

Good idea!

[torn grove]

Also I just tried out this plugin, "Turbo Switch Pro" and man I really wish I had found out about it sooner. This thing is sick. Switching between PC<->Android only takes a couple seconds now :3

[last geyser]

Hmm perhaps I am missing something that I ain't aware of, I been trying to make this animation so only certain ones that go through a trigger or press a button only they will see it, but still cant seem to figure it out

[torn grove]

I believe theres a script you have to attach to make it become a network synched object. If you dont attach that script, it is local only by default

[last geyser]

So far the only scrips Ik is Udon Behaviour and Object Sync but atm they are Syncing with everybody by the looks of it

[torn grove]

yeh the object sync script I think is the one

if you dont want your object to synch, it should just have udon behavior on it

[last geyser]

Though with the new one it automatically has sync

[torn grove]

Oh. Hm. Interesting

[last geyser]

while the old one didn't have it

[torn grove]

Wait but is there the object synch script as well?

[last geyser]

It contains it but by using that I can't tell the script to act as a trigger without behaviour

[torn grove]

No, like, a totally seperate script

It would be a seperate component below or above it

"Script" refers to one of those entire sections, like the whole square you capped there is 1 script on its own

[last geyser]

so with this one it can still work like that?

[torn grove]

Thats the script that makes your object have synch behavior

if you dont want the object to be a synched one, you want to delete that component

if you do want it to be a synched object, keep it

thats basically all it serves as a role, enabling the synched behavior

[last geyser]

Alright so like, The trigger has the behaviour, but the object that will be animated doesn't have anything

[torn grove]

You want a synched trigger to fire, on a non synched object then?

[last geyser]

But it still contains a global sync to it

[torn grove]

Like the trigger fires for everyone but manipulates a non synched object?

[last geyser]

More like only certain individuals that trigger it will see it animated while everybody else wont see it unless they do so as well

For now if someone triggers it then everybody sees it

I need it so only the 1 that triggered it will see it while everybody else can't

[torn grove]

I need it so only the 1 that triggered it will see it while everybody else can't
That just sounds like unsynched behavior then?

[last geyser]

Yeah, I need it to be unsync but idk how to do so atm

[torn grove]

What do you need to be synched vs not synched?

[last geyser]

The things that I don't want sync is what certain individuals will be using to see where certain things are at and to disable certain map effects, While sync everybody will see the things only that trigger will provide

[torn grove]

Er... hmm.

Anyone know why my camera preview doesnt match my upload icon? Is that just a graphical glitch and it will actually work? O_o

[last geyser]

I was getting the same error on my end, Dunno what the cause is

[torn grove]

ah okay so not just me, aight

Well lets see how it actually looks

Well it looks right so I guess its just a glitch, the actual uploaded image is correct
https://vrchat.com/home/world/wrld_13d7ad7f-2a01-4267-96db-af11455aeab8

[viscid reef]

yeah that happens if you have fog in the scene, just affects the preview but not the actual image

[torn grove]

nuuu

[cold raft]

Oof, i gues quest? as my world is 69Mb

i think it somehow posable to see how the 50mb is used like if its mostly textures or shaders or other things, but i have no idea how to open that overview

[viscid reef]

you can check the unity editor log to see the breakdown of asset file sizes of your world build

but its easier to use something like vrworldtoolkit which has a display for that among other things

[torn grove]

Deleted a couple things, lets see if that fixes it...

Honestly I have like zero clue why this world is so much larger than the rest

Usually my other worlds I have ripped were like... 7 to 8 mb

[viscid reef]

now would be a good time to see that asset break down lol

[torn grove]

It did get it under the mark though!

The .fbx file is just monstrously larger than the other zones. Hm.

265mb, whereas other zones are like, 30~40mb

Thats really odd, why is this fbx file so much larger...

Ill have to dig into that tomorrow I suppose, I was able to just barely edge it under 50mb so it works for quest and thats what matters for now

but definitely is sus, I wonder if it has much higher poly counts...

[ashen birch]

Any1 know a good tut for making a music visualizer that works with like a video player

[steep haven]

Hi just wanted to ask which channel is the vrchat updates?

[coarse parrot]

#announcements ?

[steep haven]

didn't find it sorry and ty

[coarse parrot]

What kind of update you're looking for?

[steep haven]

that happens in vrchat

[coarse parrot]

Like, client update? SDK update? General news? Or something else?

[steep haven]

SDK

[coarse parrot]

That should already be in #announcements. It also includes a link to full change logs.

[steep haven]

oke appreciate it !

[opal summit]

is there a way to get the player's position ignoring the play space moving?
With GetLocalPlayer -> GetPosition / GetTrackingData it returns position with playspace, which can be inside the walls etc.

[dapper lion]

you could possibly lock the players Y value, but if the playspace mover is beening used on the x or y. there may need to be some work around so it gets the center of the player area

[opal summit]

i basically want the position of player selection bulb, i believe it should be possible with some simple nodes

[dapper lion]

i think so too, but ive never really had people with playspace mover move so much that itd effect you. but obviously it did so possibly make a parented tracker to remember the users "bulb" position?

[severe veldt]

can you use custom avatars on quest 2 WITHOUT a pc

[shadow idol]

how i can make light adjust slider?

[dapper lion]

you can set a slider float to multiply the light.intensity

[shadow idol]

is there video bout that? idk anything bout unity

[dapper lion]

uuumm. possibly vowgan has a UI tutorial. i think i saw a slider demo in there

to be honest 🤔 this shouldve been a basic prefab already lol

[scarlet lake]

so I'm trying to login to vrchat on SDK3 on Unity but my login isn't working and I've reboot unity about 3 times and I got the correct user/pass

[dapper lion]

are you using a vrchat account?

[scarlet lake]

yes

[dapper lion]

what dors it say exact

[scarlet lake]

it says nothing, though it loads then it does nothing

[dapper lion]

are you highlighting something in assets/heirarchy? ive had trouble logging in when im highlightings something

[scarlet lake]

nope

[dapper lion]

check console errors

and youre solid that youre using a brchat account and not oculus or steam

[scarlet lake]

I am using vrchat account and I just reset my vrc account pass so I could get back into it

nvm got it it's not your username it's you e-mail

[queen wind]

how i add a mirror trigger in sdk3 vr chat ?

[queen wind]

done xP ty

[ashen birch]

any 1 know how to make a audio visualizer in udon

[dapper lion]

from scratch or find audiolink?

[ashen birch]

either 1 tryna make like a world

[dapper lion]

id check out audiolink as it is the easiest to set up

[ashen birch]

Ok

Can ya link me

[dapper lion]

lemme find

https://github.com/llealloo/vrc-udon-audio-link/releases/tag/0.2.3

[ashen birch]

Thanks

[shadow idol]

i still dont get it the slider light can you send pic of the graph?

[dapper lion]

um. im not sure how youd do it in graph but i do know of a way you might go about doing it in udonsharp

[scarlet lake]

ok simple question, if i want to sync a button bress via some UI with the whole world how would i do this

[dapper lion]

https://youtu.be/O3VeBzV9HgI <— this

[timid fox]

I'm assuming there is no way to randomize an ObjectPool's TryToSpawn?

[cunning mist]

None built in unfortunately, though could be a good feature request.

[timid fox]

planned to, just wanted to make sure. Would it go in Network Update or Udon Feedback?

[cunning mist]

If it's directly related to features of the networking update that would probably be correct, though it will probably be phased out as the update is no longer fancy and new.

[timid fox]

I just stuck it in Udon Feedback.

[pallid mango]

I believe there is an example script in the example folder

[pliant sluice]

supid question but can udon be used on avatars?

[dim horizon]

Sdk3 yes but Udon no. I think they're even separate versions for avatars and worlds(?)

[grand temple]

SDK3 avatar isn't udon at all, it is it's own system

[shadow idol]

sure

[pliant sluice]

ah ty

[floral dove]

It's planned FYI - I'll connect that Canny up to our internal system so you get a ping when it goes in.

[scarlet lake]

Making a few changes to a world and instead of stairs I i'm trying to figure out how to teleport the player there. Is there a built in script, or a script I can download for that, or would I have to make my own?

[dapper lion]

i have a teleport prefab you can use

[scarlet lake]

I'd love that

[fading cipher]

So what’s this whole reliable sync thing I’m hearing about from UNU?

[cold raft]

It's the future!

[scarlet lake]

whats a udon is that like a noodle?

[tacit harness]

So for my question i need to toggle something if a player crossed a specific spot in the map

how would i track that ?

Im pretty new to making stuff in udon so yeah

[tacit harness]

if you can help me pls dm me or ping me in here ^^

[fiery yoke]

@tacit harness In VRChat specifically you should use the event "OnPlayerTriggerEnter" on an object that has a box collider marked as isTrigger.
This event will trigger, when a player enters the collider. You can then execute your other logic from there.

[tacit harness]

let me try that real quick ^^

[spare flame]

Also after importing the SDK into your project you can find UdonExampleScene in your assets, highly recommend you check it out for a bunch of common Udon interactions

[tacit harness]

worked perfectly thanks for the help ^^

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

[scarlet lake]

so it is like a noodle

tasty 😊

[pallid remnant]

is it possible to have the same global toggle in udon that sdk2 uses? the one that says "AlwaysBufferOne"

[fiery yoke]

The concept of a buffer does not exist in Udon, as it is inherently a bad concept.

[pallid remnant]

i see

so it's not possible to have late joiners sync to the most recent events then?

i would like to make a global toggle for a piano

[dapper lion]

i think there is a global toggle example in the examples scene for udon that should automatically sync up wIth late joins

[pallid remnant]

that would be helpful

is it in thefiles somewhere?

[dapper lion]

i believe so. remember to use the latest sdk

if all else fails. get udonsharp and use their globbal toggle example

i always trust that toggle

[pallid remnant]

i think i already have that because i'm using the pooltable prefab

maybe that is the best choice then

oh i found it!

i cant seem to drag and drop the script

[dapper lion]

you add an udon behave first. then drag the script

[pallid remnant]

i did add one, but when i try to drop the script in "program source" it doesnt accept it

[grand temple]

Udon is not meant to sync with late joiners by events. Instead you would use synced variables for that

[dapper lion]

i think youre attempting to add a cs script and not u#

[pallid remnant]

oh!

i just noticed the green ones with the u

works!

awesome, thanks guys

i was looking for this for a while

[fierce verge]

Can I make the color of a material change using udon?

[fiery yoke]

Yes. You can.

[fierce verge]

okay

so I have the setcolor node

but what name do I fill in?

[fiery yoke]

the name of the shaderlab parameter, that defines your color in the shader of the material.

[fierce verge]

uhmmm I don't get it ':D

[fiery yoke]

Yeah materials are complicated. Essentially the material that you define in Unity is a "shared material", every renderer that uses the material gets an instance of the material. Modifying the instance will only change it for that one renderer, changing the shared material will change all instances as well. Thats how I understand it at least.
A material is a shader, with a bunch of serialized settings that configure the shader to run in a specific way. every "parameter" of a shader has a name in the shader like "_MainTex" which is usually the main texture. You need to tell the shader/material which color you want to change since a shader could have multiple color parameters.

[fierce verge]

ahhhh

it has only one tho

[fiery yoke]

I think you can right click on the material and click on "Edit Shader"

it will then tell you what the color parameter is called

[fierce verge]

ahhh I see

_TintColor

[feral valve]

So I'm completely new and the video I tried to follow was outdated.
How can I do mirror quality toggles with 2 buttons. And only have 1 or none on at a time. Ping me

[twilit breach]

Anyone know what determines the VRC pickup highlight? Sometimes it feels like it surrounds the collider, other times the mesh, and sometimes if the parent doesn't have the right stuff it finds the childs mesh and sometimes it finds nothing in children and has no highlight

[dusk lance]

Copying from the wiki I helped write years ago:

You'll notice that when you go to Interact with something, a highlight will appear around the object. The shape of this highlight will follow these rules:

- All enabled Mesh Renderers on the object or on children of the object will be used to make the Highlight. If any of them are marked as batching static, they will be ignored.
- Skinned Mesh Renderers cannot be used for Highlights. If your object is a Skinned Mesh, either switch to using a Mesh Filter with a Mesh Renderer or use a Mesh Collider to fake the Highlight instead. Note that when using a Mesh Collider, you cannot use the Is Trigger option unless it is set to Convex, which will ruin your shape. For these cases you can set the Layer to Player or Walkthrough in order to make it non-solid.
- If no Mesh Renderers are found, any colliders on the same object will be used instead. If there are multiple colliders on the same object as the Interact, whichever one is higher up on the inspector list will be used for the highlight. However, all of them can still be used to activate the Interact even if they don't highlight. Conversely, any colliders on children of the Interact object are completely ignored when it comes to both highlighting and interacting.

[trail hazel]

as far as udon goes, is there any consensus on method for desktop-exclusive UI (that is, UI that appears on the vrchat window, but not in a headset)?

i want to create UI that is diegetic (like how in half life alyx, your hand is where you check your health), but that has screen-bound UI both for actual desktop users and for third party watchers (e.g. on a stream)

the main thing i can think of as far as unity-pure methods is to tie the desktop UI to a rendertexture and render a plane with a shader that maps it to the screen with that texture but that feels like a very roundabout way of doing it

[dusk lance]

If you create a canvas and keep it on screen space, it will only show up on your desktop screen and not in vr. Add the vrc Ui shape to ensure the correct camera.

[floral dove]

you can also check IsUserInVR to hide/show it so it's not trying to render at all for VR users

[trail hazel]

man that feels a lot more obvious now that you say it

[trail hazel]

also yeah, but the idea is that it continues displaying when users are in VR, it just doesn't display for the actual VR user (only whoever might be watching them, or on recordings)

[floral dove]

ohhh, yeah I get it. Yep - screen space will work. That's how I show the virtual camera view for recording / streaming in this world while the VR user sees the world normally: https://vrchat.com/home/world/wrld_37caf537-8d92-4d8a-8d40-407d60ecb143

[feral elk]

Quick question, seems like it should be simple, but I can't figure it out

What node do I use to set an int variable in the graph?

[feral elk]

Oh nvm figured it out

For others in the same situation: Hold control when dragging the variable out

[feral valve]

If it a too much to explain. I can learn off a prefab.

[feral valve]

Or if someone has a video that isn't outdated, that would help too.

[floral dove]

Check out the mirror toggle in the UdonExampleScene for a working prefab with one mirror. You could easily duplicate the mirror with different settings to control that one separately.
https://docs.vrchat.com/docs/udon-example-scene#mirrorsystem

[feral valve]

I did make a upon graph to toggle objects. I'm just trying to make sure only 1 can be on at a time

[feral elk]

Add a node after toggling your object to disable the other object

So for the high quality mirror: ```

On interact --> [Toggle stuff goes here] --> Gameobject.setactive
[ ] bool
[ Low quality mirror ] - o gameobject```

[feral elk]

Having a new issue: I've got a node graph that waits for an audio source to start, sets a variable to true, waits for the audio source to stop, sets that variable to false, and does some other things unrelated to that variable

The basic idea is If audio source isplaying is false, set var to false and do other stuff Update --> Branch if var is true < If audio source isplaying is true, set var to true

This works well the first time, it sets the variable to true and then waits for the audio to stop, but after it does the other tasks, there's a brief period of time where the variable changes from true/false to the string "d4ca6c53-e9ea-415a-abdd-190f1410d54c", which causes a "Cannot retrieve heap variable of type 'String' as type 'Boolean'" error and stops the program. Any idea what might be going on?

[floral dove]

Hm, sounds like maybe something is miswired in your graph? It looks like the value is changing to the internal id of the variable instead of the proper Boolean value. It also could be a compiler bug - we'd need to see the graph and the assembly to know.

[feral elk]

It seems to work if I use a const bool wired in to it instead of using the checkbox on the set variable node. I do have an older version of udon in the project, so i'll upgrade tomorrow and then go through the proper bug report channels if it still doesn't work unless I use a seperate const bool. Thanks!

[floral dove]

Ah yes - it does sound like an issue we fixed a few versions ago. Upgrading to the latest SDK will likely fix it, there was a flaw in the compiler logic for the set variable nodes.

[feral elk]

Ahhh Ok, I'll try that soon, thanks for your help!

[tacit harness]

so hello to everyone

I have this udon programm i made its supposed to turna collider on when the object is beeing picked up and off when it gets dropped

This programm works but only once in each direction it turns the collider on once and turns it off once after that nothing happens

[strange shale]

errors like this are usually because of an error on the end of the function like OnDrop
errors like that usually turn off the component which would prevent it from playing after the first loop
you can check your logs for errors or get CyanEmu for testing features like this in unity so you can check the console for the error as it happens

im not an expert by any means but i hope that helps

[cunning mist]

I don't think you can set the owner of an object to be null... I haven't tried, but I can't imagine that being good...

You also don't need to set yourself to be the owner of the object you just picked up, VRChat does that automatically.

[fading cipher]

So this is only gonna be my second time updating the SDK. Do I still have to delete the same folders as usual before updating the SDK?

[tacit harness]

I remade the entire controller and now it works

[tacit harness]

I have never tried but a owner check does show that it is null

[cunning mist]

Depending on how old it is, maybe. If your last update was recently than there's probably no issue.

[tacit harness]

Wait xD i watched your tutorials btw xD

Didnt find any other good ones out there

[fading cipher]

vowgan is gud for beginners, we all love him

😬 I'm not sure if my sdk is new enough ;-; My current version if the input events ver I believe

[tacit harness]

Legit i searched for tutorials so long and they either outdated or not really good
But his tutorials 🤌 very good xD

[cunning mist]

If you import the new SDK and clear the console and don't have any errors, you're fine. Otherwise you'll have to.

And happy to help haha

[fading cipher]

thanks vow, here's goes e.e

uhhh, quick other question

do you always force to import all, or does it automatically import only diff? https://i.imgur.com/m9oRLAZ.png

[tacit harness]

When you just do it like this it overrides all the old ones with the new ones

[fading cipher]

awesome ok

[tacit harness]

The weird arrows on the right mean reimport/override if it says new its something thats isnt in there yet if there is nothing next to it it means it already has the exact same thing in there ^^

[fading cipher]

ohhh, that's good to know, thanks

[floral dove]

If you're just getting started with Networking, we've got two new Tutorials covering the concepts and some step-by-step instructions:

[rough beacon]

this work great. but for weird reason only the master can click on it. how do i fix that?

[floral dove]

https://docs.vrchat.com/docs/network-components#vrc-object-pool

To make an object active, the Owner of the pool triggers the TryToSpawn node, which will return the object that was made active, or a null object if none are available. Objects may be returned to the pool by the pool's owner, and automatically disabled, via the Return node.

that's how it works

[feral elk]

Yooo upgrading my SDK fixed my issue last night! But now I have a new one! 😅

Arrays don't appear to be returning the correct things. I have an array with 3 items (photo attached) that I iterate through with a variable. For some reason trying to get the second object returns the object that the udonbehavior is on and not the object that's second in the array. Even stranger, I made a quick graph to try to see what the array is seeing (photo also attached) and it prints the 1st object then the 2nd object twice instead of printing the first, second, and third object.

(Node graph for the program mentioned above)^^

[rough beacon]

hmm. not sure why it was made like that but oh well. so there no real fix for it.

[magic kiln]

Hey Fam! total noob here, building my first world pretty happy with it so far, my question: I am using the PBR stage equitment prefab models for my stage and dj lights. I want the color of the lighting to match the colors being played on the video player. IS there a video and tutorial someone can point me to that shows how to do this?

[rough beacon]

i not sure if this to much to ask for. can i request TryToSpawn work for all player. not just owner. if i want to limited just owner. i can just add this.

[floral dove]

you can make a Canny for it, yes

[rough beacon]

you have a link for that

you can just pm me

[floral dove]

thank you

[magic kiln]

Is there a way to get an undon trigger/toggle that can reverse a pre-fab objects animation?

for example, if a ball is spinning to the left is there a way to righter it to spin to the right?

[rough beacon]

not sure if this help you.

[feral elk]

I would recommend checking out the automatic door tutorial (https://www.youtube.com/watch?v=95jRByYHE4Y) to get an idea of how to work with animator states in udon. I think at some point it also tells you how to reverse an animation.

Essentially, what you're going to want to do is create an animator parameter that switches between the spinning forwards animation and the spinning backwards animation, and control that animator parameter using udon.
^^If that paragraph makes no sense to you, it should make more sense after watching the video.

[floral dove]

Introducing our first-ever World Jam! Download a starter project and make some Drawing Tools: https://itch.io/jam/vrchat-sketchbook-jam

[stark adder]

😄 interesting Wish I had time for that.. Still fixing bugs that I created while switching over to UNU 😄

[wanton oxide]

i am updating my world right now to take full advantage of UnU

once i'm done with that tho

count me in

hell ye

[fading cipher]

Did VRC change input events when they updated? I updated my SDK and now one of my scripts is broken and I have no clue what could be different- nothing in that script is networked

[floral dove]

we added some Input Events a while back, but didn't remove old ones

[fading cipher]

I've been using the new input events system and it worked fine a week ago, and I'm not getting any errors in any of my broken scripts; they just don't do what they used to :p

[wanton oxide]

I have two questions:

• Can we collaborate on this (for example, me and a friend)
• How lenient is the "drawing tools" requirement (can we make a game where you draw a path for something, or does it have to be a drawing?)

[floral dove]

Yes, collaborations are great!
Drawing a path for a game sounds like an excellent use of the theme.

[wanton oxide]

Awesome

[fading cipher]

Hey momo, quick update that I think I created a nullref by deleting old (disabled) objects I don't need anymore

[ivory panther]

Do we have an eta for synced animations? A lot of my world designs really relied on it in sdk2.

[wanton oxide]

you can write your own system to replace synced animations already

automatically synced animations would be nice but its not needed if you just use the new tools :P

[atomic sinew]

Is udon sharp scripts already network synced ?

[fading cipher]

Yeah I fixed my issue o/ working on my next bug now

[lofty pewter]

udon ppl what do i use for world building

[floral dove]

Udon

[tacit harness]

You download yourself the udon sdk 3 for world building

[regal swift]

anyone able to help explain to me or show me a video/page link on how to make a udon passcode in world?

[fiery yoke]

Do you mean something like a keypad to unlock a certain area?

[regal swift]

yes

[fiery yoke]

It depends on how exactly you want it to work. Usually its best to do that with UI Buttons and Input Fields, however then you need to know how to use Unitys UI system in VRChat and how it works in Unity in the first place ofcourse. The simpler method is to use VRChats "Interact" thing, but when you put a lot of Interact boxes next to each other it gets really difficult and annoying to select a specific one.

[ashen birch]

if any1 would like to help setup a few things feel free to dm

[hushed silo]

Is there a good non-video documentation for Udon? I don't learn very well from Video tutorials. I'm mostly looking for like a rundown of some of the udon graph basics, for example what some of the node commands do. That seems to be my biggest hiccup currently.

I tried the VRChat Documentation and found it a bit lacking in clarity

[unreal grail]

is OnPickup a networked event or a local event?

[floral dove]

Have you read through these pages?
https://docs.vrchat.com/docs/udon-node-graph-upgrade

[floral dove]

This might help, too - shows a lot of the common nodes in the context of working programs: https://docs.vrchat.com/docs/udon-example-scene

[hushed silo]

I have indeed, its still not quite what I'm looking for.

[floral dove]

Are there any particular nodes about which you are curious? Or something specific you're trying to do?

[hushed silo]

I'm more of looking for an overview of like what some 'nodes' do, what the colors mean exactly. Are the nodes something that translate to something else in unity?

[floral dove]

OnPickup is a local event for the player who picked up the object.

[floral dove]

The colors of nodes differentiate Event nodes vs value nodes and the port and noodle colors are different between some classes. You're right that those should be documented somewhere.

The nodes themselves generate Udon Assembly, and reflect many Classes, Methods and Properties which would normally be available in C# in Unity.
https://docs.vrchat.com/docs/what-is-udon#whats-this-udon-thing-anyways

[hushed silo]

Ahh, thats helpful, thats more of the information im looking for

Thank you

[raven wadi]

Hey does anyone know a good tut for adding visemes and blinking to an avatar?

[floral dove]

This channel is for Udon, our World Scripting language. Check out #avatar-help for questions about avatars

[raven wadi]

kk thanks

[dapper lion]

local

or i have been networking them for no reason lol

[chilly crater]

You can't raycast players, right?

[dapper lion]

@chilly crater you cant sadly. i think (ive tried like 5 times, but i couldve missed something)

[chilly crater]

Meh, I guess I'll have to puzzle out a way to assign from objectpool on join and position sync that on a layer.

This will work, right?

That should give one to everybody when they join, and when someone leaves, it should find the one with the invalid owner and return it.

[cerulean linden]

Wow, there’s an objectpool type now? When was that added? [sorry if derailing your discussion]

[chilly crater]

The last update.

[cerulean linden]

Wow, that’s a game changer

[dapper lion]

@cerulean lindenyesh, very useful lol

@chilly craterthats a smart work around

[chilly crater]

So was that udongraph basically what I want?

If that works, I just have to figure out layermasks for the raycast.

[dapper lion]

is this supposed to support on facd?

[chilly crater]

facd?

[dapper lion]

face

oh nvm,. im reading graph as a different graph coding system 😅

[chilly crater]

oh

I figure I give everybody a default unity capsule with the script on it.

[dapper lion]

what was "get length" for?

[chilly crater]

and just check for owner instead of VRCAPI

[cerulean linden]

I have an idea for a hack if your solution doesn’t work

[chilly crater]

I have a transformarray for the objectpool

it fetches the children.

[dapper lion]

capsule idea i think is clever and much nicer than the overcomplicated solutions i was thinking tbh lol (bolt an invis basic avatar to all 82 basic bone positions)

[chilly crater]

oof

[dapper lion]

ok that makes more sence

(im also going off of more U# logic, so get length right there looks weird to me)

[chilly crater]

lol, right?

I usually do a Vowgan and do it in graph then plot out in U#

Except for raycasts, they don't make any sense in graph form

Lately I've been checking collider names for contains on raycast hit.

[dapper lion]

raycasts are very interestings. you can get what i call "fake raycasts" with scripting and idk why but it perplexes my basic logic sometimes lol

[chilly crater]

then throw a bunch of tags in names. [Shoot] [NoDecal] [Player]

[dapper lion]

thats smart

[chilly crater]

so you have one script do different events per tag

[dapper lion]

ah ic

[chilly crater]

I threw together a ghetto gun that had a decal objectpool that threw them at impact. or killed an NPC, or changed colors of a target.

This graph should let me do enemy vision raycasts. Well, spherecasts

[cerulean linden]

Can I ask you about how the new objectpool feature works?
Can it be used for objects with udon scripts that have position syncing behavior?
What’s the advantage of using it over older methods?

[chilly crater]

Someone above said that it reduced a ~400 line script they had before to ~60 lines.

It streamlines the process.

Originally, you had to to a foreach loop with an object pool to spawn from it. Now you just do trytospawn and it will do all that for you. Despawn sends it back to the object pool and disables it.

[floral dove]

https://docs.vrchat.com/docs/network-components#vrc-object-pool
https://docs.vrchat.com/docs/udon-example-scene#objectpool

[chilly crater]

it just ocurred to me that doing an isvalid check on an object after a player leaves is not a good idea. the itemdefaults back to the networkmaster

I think I smoothed out that issue.

Just have to throw in a customnetworkevent on on playerjoin to have everybody set the text object based on owner name

Or would that be better as a synced variable

That could get pricey on the upkeep.

[chilly aspen]

Hi, I have a question. In my world I have about 100 game objects all with a synced integer.

When I Build & Test the world with 2 clients, 90% of the time the synced integers works fine. The other 10% of the time the synced integers refuse to sync. This is probably because a death-run was fired due to exceeding limits when all 100 game objects were active at the same time.

Does anyone have any tips to prevent a death run? These seem to be happening randomly.

[floral dove]

Are you using the latest SDK? Can you try switching to Manual sync? You'll have to add a RequestSerialization after you change the value, but it should reduce the network load.
https://docs.vrchat.com/docs/udon-networking#2-manual-variable

[chilly aspen]

Oh I'm behind an SDK, I'll upgrade and try seeing if that fixes it.

[chilly aspen]

Ok things are good now, I also had a few game objects accidentally set to manual.

[chilly crater]

Is it a weird thing of cyanemu or did I do somethign wrong with my objectpool, it's assigning the second item to me whenever I test.

[magic kiln]

Are there any audiolink pros who has the time to help me through it! I can really only get the prefab cubes to work, I am trying to figure out how to make audio reactive light beams for a club totally lost

[woeful glade]

ok lemme start with i am very new to vr chat world development so idk much and ive just gotten started.
The first thing I wanted to try and do was to change the text of a text ui object when a user clicks a button to their name and ive got all of it setup in an udon graph except getting the actual player's name to assign. I would love help to get the player's name cause i cant find out how (i assume its something in playerapi)

i know this is simpler than other people's questions but any help is welcomed so i can get to know udon

[fiery yoke]

To get the name of a player you need to get the players api and then from the api get the displayName. To get the local player you can use Networking.get_LocalPlayer.

[woeful glade]

what the difference between playerapi[] and playerapi

[fiery yoke]

the [] indicates an array in most programming languages

[woeful glade]

ye, just wondering how its different for udon

cause they seem to be the same

[fiery yoke]

Its not different at all. Udon is still built on top of C# .NET and therefor works very much the same way.

[woeful glade]

also ty for the help before

[light nova]

hey there, got a question regarding the ownership of networked objects.
so if i understand correctly, some time ago when i wasn't the owner of an object and wanted to change something about it, i needed to request ownership, wait for approval, and only then was able to do what i wanted to.
now, to reduce latency, if i request ownership i pretty much assume that it was approved, and i can do whatever i want immediately.
so why won't Udon go a step further and simply allow objects to be public (i.e. "without an owner"/"everyone is an owner"), so anyone can broadcast new values for them without effing around with current pretended ownership?

[woeful glade]

i can't get the text object to change text and im really not sure why, if anyone can help itd be appreciated, I keep getting an error

An exception occurred during EXTERN to 'UnityEngineUIText.__set_text__SystemString__SystemVoid'.

this is my scene layout (its only setup for testing)

[light nova]

you sure that your UIText variable is public and has an appropriate gameobject assigned, and also that GetComponent does not return null?
have you tried making UIText of type Text so you don't need to use GetComponent?

[woeful glade]

lemme give those things a check

[woeful glade]

got the same error even when i make it directly the text component

[light nova]

both work for me

[woeful glade]

how difficult would it be for u to dm me the unity scene so i can disect it and see where ive gone wrong

if thats not too hard

[signal kestrel]

A scene doesn't include the scripts, they'd have to send the scripts too

[light nova]

yeah, just packed it with dependencies, ignoring the udon stuff

[fading cipher]

If a player blocks another and they can no longer see each other, then they try to get that player’s HumanBodyBones.LeftHand for instance, does that error out?

[flint urchin]

Yes

[fading cipher]

Does blocking a player preserve their rig for Udon purposes and just make them invisible?

Ah so I need to make an edge case for that 🤔

[flint urchin]

So always check if it's valid

[fading cipher]

Ohhh IsValid, perfect I have yet to need that

[lofty pewter]

so is this what i use to world build in vrchat

[fiery yoke]

You can however still get any players api and call get position and get a valid and correct position.

[fading cipher]

Wait, so playerapi.getboneposition() still works if you're getting the pos of a blocked player's bones?

[fiery yoke]

no playerapi.GetPosition() definitely works. I dont know about tracking data or bone positions

[fading cipher]

oh getting their actual position, okay

Thanks for that o/

[shut lodge]

In the VRCPlayerAPI is the GetPlayerId returning the unique int code for the player in all of vrchat? I had thought that was the case but when I ran locally I got a 0 or a 1 but now I'm thinking that was just a quirk of running the client locally etc

[fiery yoke]

the "player id" is more like a session-wise id

[shut lodge]

dang

[fiery yoke]

VRChat is notoriously not the best at naming their stuff lol

[shut lodge]

I had tried to use displayname to identify players returning to my world to do diff things for them. But I'm having trouble encoding some display names and I know they change too so not ideal

[fiery yoke]

It starts at 0 and everytime a player joins the id is incremented by 1

There is no UUID for players in VRChat which might be a design philosophy so you cannot directly target a player. So yeah displayName is the next best thing, as most players tend not to change that too often

[shut lodge]

ok thanks

[eager olive]

That's good info, thank you! Would be nice to have that on the wiki page at https://docs.vrchat.com/docs/onpickup

[floral dove]

Good point. Here is the section for Udon specifically: https://docs.vrchat.com/docs/event-nodes#onpickup
Maybe it would be helpful to give info for each event on whether it only triggers locally or for everyone.

[feral elk]

Alright, so I've rewritten the program I was having trouble with last time and definitely am having some odd behavior with arrays.

Here's my node graph to initialize a couple variables, then set the first gameobject in an array to active while deactivating the rest. It does not work and at first appeared to do the opposite, leaving everything but the first active. After logging the int index and gameobject, it appears that while the int index iterates correctly, the gameobject get node always returns the first object. Any ideas why?

[light nova]

It does not work and at first appeared to do the opposite, leaving everything but the first active.
well yeah, if index == 0 you're setting active to false, and true otherwise

also you can simplify it by just doing SetActive(index == 0)

[magic kiln]

is there an audiolink expert out therE?

[feral elk]

Oops, yea, posted a screenshot of my testing code where I crossed the true and false, but I've tried it both ways. The underlying issue is that using a food loop input to get something out of an array always results in the first item.

[light nova]

oh, i'm pretty sure it's the bug in Udon that it doesn't copy the get-element-from-array assembly code if you reuse Get blocks. use separate Gets, or - better - simplify it as i've said by connecting the result of Equality to SetActive's value, removing the Branch and the other SetActive

[feral elk]

Ah that makes sense, thanks for the suggestion, I'll try soon!

[chilly crater]

Is there a faster way to populate the list of an Objectpool instead of dragging and dropping?

[ivory steppe]

Hey everyone, I wan't to add a card game into my 3.0 udon world however I've looked far and wide for tutorials/prefabs without success 😦
Can anyone point me in the right direction?

[grand temple]

If you click the little lock on the top right of the inspector that locks you to the object pool, then you can select all your objects at once without the inspector switching to them. Then you can drag all your objects into the pool at once

[cunning mist]

You can lock the inspector and drag as many objects as you'd like into the Pool name. Here's the process used for Udon, you don't need to make a second inspector though since it's just for gameobjects.

Oh

[chilly crater]

thanks much

Wish I knew that before I did 40 items separately

I should probably watch the rest of your videos

[ivory steppe]

your videos helped me out a ton @cunning mist ! thanks for the help 😄

[cunning mist]

There's easily millions of things that make everyone's life easier and they always make you reconsider possibly weeks of your life spent not knowing them. It's practically a daily occurrence these days for me...

Happy to help!

[chilly crater]

back to playing with raycasts

[ivory steppe]

Any ideas for this Vowgan? I can't seem to find any prefabs like there are for pooltables, beerpong & wheel spins

I have a set of cards that I still need to network however I can't figure out how to reset their position after they've been moved

[floral dove]

you can use an Object Pool, which has a Return function which will reset an object

[cunning mist]

I actually just had a question on this today. My plan is to use Object Pools as well, though since Momo hinted we will be getting a TrySpawnRandom or whatever at some point, that will make things much easier.

[chilly crater]

Objectpool seems pretty appealing there. Trytospawn > getcomponent VRCPickup and force that player to hold it.

Go a little snazzy and put a blank card on top of the deck, and on pickup have it try to spawn, drop that card and force you to hold the spawned card, return the blank card to previous position.

[cunning mist]

Since you can't force a player to pick something up, my implementation has a fake deck of cards with a single card on top, then as soon as that card is picked up, it spawns the next card at the top of the deck.

[chilly crater]

wait, you can't force pickup?

Oh, I read the forcemode documentation wrong

[untold echo]

Could you (or anyone here) elaborate on this? I hate asking something that is seemingly really simple but I am an Udon noob (like explain like I'm 5 kinda noob) and I'm just trying to make a button to reset all the pickups in my world. I've been having a hard time finding recent instructions for SDK3 and the new Udon update(s).

I first tried using your package from last month and it works, but the button only resets the pickups once then doesn't work after that. (I'm probably doing something wrong) (#udon-general message)

Should I be using Object Pools instead now? I just don't know what the graph should look like.

I'm new to world building and Udon is hard

[coarse parrot]

Take a look in an example for the latest sdk. There's an object pool example included.

[ivory steppe]

Thanks for all the tips guys, I hadn't heard of object pool yet so that should be helpful!

[dapper lion]

does constraining multiple objects onto peoples avatars cause any huge network performance issues? i want to constraine at least 160 spheres onto 10 players, mainly just for fun, but also as like a proof of concept to possibly put world data access onto people easily

[ivory steppe]

Been following the Toggle Colliders video from Vowgan to the letter (I think) and it does exactly what it is supposed to do minus that when I try to turn the colliders back on it simply doesn't turn them back on... so they are there to begin with but once its toggled it can't be toggled back on... what am I doing wrong here?

[void ridge]

Post a picture of your graph

[void ridge]

Looks right to me

Do some debugging, maybe? Add a Debug.Log node after the Exit flow of the for loop, and try to get a log message after the loop completes

[ivory steppe]

so just the debug.log node after the set enabled node and it'll give me a log message?

[void ridge]

ehhh probably don't do that, because that will log a message for each element of your array, which would be 56 messages hah

No, put it after the Exit arrow on your For node

[ivory steppe]

Ah xD gotcha

[void ridge]

You also need to add a string that Debug.Log should output. You can use a Const string node, or if you want to be fancy (you should), figure out String.Format so you can include the boolean value of Get isOn in your log message

[ivory steppe]

I decided to start over but do a button this time instead of toggle

would I have to change a lot in the graph for it to work as a button?

[ivory steppe]

Re-did the whole thing and its still doing the same issue

[dapper lion]

whatre you attempting to do?

[ivory steppe]

This is how the colliders are setup and it only toggles them off once I click the toggle button but then if I toggle again it doesn't go back on

I got an idea! I'll just make a button that works the same as a mirror toggle but instead it'll toggle the collider game objects

[dapper lion]

ah. what does graph look like know? also double checking! are you using a vruishape on your ui button?

[ivory steppe]

Still looks like this

[dapper lion]

also i think default unity UI has a bool for colliders. so no scripting is required (iirc)

ok. loading image

[ivory steppe]

and yeah the vrc ui is working because it toggles it once but not again after

[dapper lion]

so i think what you need to do is make it so it can tell if the collider it gets is either “isenabled” or “isdisabled” because i think what its doing is making sure that all colliders are on. right?

[ivory steppe]

Its making sure they're off

however it doesn't toggle them back on

[dapper lion]

ok. so i think you need to make the graph do a toggle rather than a state check

idk if thats how vowgan did it. but thats my best guess as to what the issue is

[shadow idol]

question bout how i can toggle pickups?

[shadow idol]

not sure try to use this
https://i.imgur.com/xMS2qcN.png

[dapper lion]

um lol, follow what the person above is doing but attempt toggling the vrcpickup bool

oh there we go

thats the thingy lmao

[shadow idol]

tried it before was working

but now doesnt work idk why

[dapper lion]

were you testing it with more than 1 client?

[shadow idol]

no in new project

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

null?

[dapper lion]

what does your console say?

[shadow idol]

i was getting udonsharp error but i cleared fq

[dapper lion]

ah

wait, so does it toggle once or not at all anymore?

[shadow idol]

does nothing

https://i.imgur.com/LIJH8Gn.png

in the other project is working fine

[dapper lion]

ok. is the vrcsdk panel present anymore?

[shadow idol]

wdym

[dapper lion]

well rhats a good sign

and for sure no console errors?

[shadow idol]

yes

[dapper lion]

did yiu update the sdk?

[shadow idol]

how i can reinstall udonsharp?

[shadow idol]

no

[dapper lion]

you need to install udonsharp?

[shadow idol]

had for pool

it

[dapper lion]

ok. then i honestly dk whats the matter. does the button youre using have a collider? lol

[shadow idol]

yes box

[summer lion]

where is transform get position in the new udon?

[ivory steppe]

is there a way to toggle multiple game objects with 1 button?

[shadow idol]

yes

[ivory steppe]

got a graph example?

[shadow idol]

https://i.imgur.com/JJfrpkj.png thats works for me

[ivory steppe]

Wonder if it'll work with a button if you use Button.IsActive instead of "Toggle.GetIsOn"

[dapper lion]

is there a way to change your avatar while the vrc menu is open?

via pedestal or any other method?

[magic kiln]

Has anyone found a way to get light beams to sync to AudioLink? I've just about given up...

my latest attempt is using the reactive surface alpha smooth shader...

[dapper lion]

@magic kiln elab plz?

do you mean actual sync pos or like slider adjustments?

[magic kiln]

just trying to get the lightbeam to match the color effects of the lights attached to flash change colors etc.

[dapper lion]

what light beam? is this a shader? if youre using projectors, it will not work because it is not exposed

[magic kiln]

so my test lights in the scene work perfect. and the spotlight attached to this projector is synced up so on the walls I can see the color turn on and off. but the beams nothing

also I am a total noob

[dapper lion]

ah yes. so you will need to use “audioreactivesurface” and edit the material variables a little. as the beams are their own shader. and audiolink does not know what colors it needs to change

you may need to do some script editing

can you find where the .shader for the light beam shader is?

are you wanting to edit intensity or color?

[magic kiln]

the shader is the AudioReactiveSurface_SmoothAlpah

I just want so users can see the light beams as they move around the space, and the beams match the color movement and plus as the spotlights

[dapper lion]

oh so you want the colors be synced with everyone? so like me and you both see red when a loud bass hits?

[magic kiln]

correct. So if I change the shader to the base audioreactivesurface and not the audioreactivesurface_SmoothAlpha it makes an ugly ass cone and I lose the nice particle effect it currently has

[dapper lion]

but that should also have this same issue? may i suggest going to the discord server linked in the audiolink page. the people there may be able to help with light colors not lining up properly

[magic kiln]

i've been hunting for it do you have a link?

[dapper lion]

um. it should be on the github. if it isnt ill totally send link

ok, its not there. standby lol

[magic kiln]

[tacit harness]

If i would like to make something random for example the spawn of a few object so for example either a ball or a cube or something else spawns how exactly would i randomize that ?
I just need something to trigger a random effect/object

If you can help pls dm or ping me ^^

[tacit harness]

Or if thats easier if i use a random range node can i somehow convert that to a bool on or off value

i tried doing that but the problem with that is that it removes the randomosation in my case for whatever reason

Thats what i tried

[broken bear]

Is there a turning-of-a-dial prefab out there? I recall seeing one I think from the development video but not sure if it was otherwise available

[dapper lion]

i think yodo has a turn-dial

not sure how it works

[tacit harness]

Or is there a way to instantly generate a random bool value

[broken bear]

Likely collider-spokes of the dial hitting a trigger area but I would love the example of the rotation interact (especially desktop), single direction rotation is fine for my use case. Desktop may be animate the rotation slowly while on interact. I guess I can do that for vr but would love a direct rotation , maybe using constraints

[dapper lion]

i think constraints would be the most efficient way

[ivory steppe]

Is there a way to randomize objectpools?

[queen crow]

in which way?

when you TrytoSpawn() it spawns a random one and not the next one. not whit the opject pool from vrc then you need to make your own

so far as i know

[ivory steppe]

Yeah TrytoSpawn so it spawns a random object from my pool of 52 (card game)

This just spawns them in order

[tacit harness]

Why is randomisation so hard qwq why cant udon just have a random bool option that would make my life rn so much easier cuz i cant figure it out how to get that

a random bool state is all i need

but i cant find anything

qwq

[queen crow]

It's not hard

For my game i use a int array each. Length 40 and each card has a id

I get whit random range a random int. When. It's -1 it's already in game and get a new one until i have that is not -1

[ivory steppe]

Could you show the graph for it? 😳

[queen crow]

i use udonsharp. find that easier for me.

[granite ravine]

is there a way to load an image from the internet with udon?

[ashen birch]

any 1 wana help me figure sum stoofs out

[feral elk]

As far as I know, not directly. You can, however, load a video from the internet using the unity video player component. If you're able to host a 1-frame video instead of an image, that'll work instead.

Here's some documentation on using video players with udon: https://docs.vrchat.com/docs/video-players

[granite ravine]

because I wanted to create an ui like a gallery with a slider at the bottom

[feral elk]

The video thing should work with you then, but keep in mind that vrchat has a rate limit for video players where you can only load a URL every 5 seconds. Additionally, they suggest to not have more than 2 players in the world. You should use a single video player and use udon the change out the URL every 5 seconds.

[granite ravine]

hmm okay, thanks

[feral elk]

Question:

I solved the array problem I was having yesterday (thanks Shingen!) but now have a new one 🙂 . Using the two log blocks here, I have confirmed that the value of CurrentObject is 1, but the GameObject[] Get node returns the object that the udonbehavior is on instead of the second item in the array. I have tried to remove and recreate the gameobject[] get and gameobject[] Songs variable get block and tried duplicating and deleting the program, which did not change the output. How do I get the CurrentObject'th item of the Songs array?

[long stream]

I am completely new to making a VRChat world and using SDK 3 for making a VRChat world. I am familor with blender, and some stuff with unity.

I am really confused on how SDK 3 works when making a world - I have heard it's too complex compared to SDK 2, but then I don't know ether for making worlds so shrug. I would prefer to use SDK 3, install Udon, but I don't know anything of coding. I would prefer to just use prefabs and with as little coding as possible. Please help me by recommending me some videos that can help me get started on using SDK 3 world to VRChat. Thank you

[light nova]

idk prefabs of what you're talking about, but models alone are fine and all that, but they just, well, are. period.
if all you want is a bunch of decorations on your map then you don't really need any any code. for synchronization of those decorations you may need to use some components that have code underneath, but you won't be playing with it yourself.
if you want some kind of interactivity, though, well... how do you expect to do it without code?

[ivory steppe]

There's some pretty accessible prefabs out there for stuff like pool tables, spin the wheel and beer pong

Also other fun stuff like jetpacks

[long stream]

How does one integrate udon prefabs (like the pool table, etc.) into the unity project? I don't mean the part where you drag and drop them in, I mean isn't there still some setup to be done to those objects or something needing to be done to the project so it can be uploaded to VRChat? Like something with adding components and settings. I'm so new when it comes to world creation. I have never touched VRChat world creation. :< I'm really familor with avatar creation though.

I know I can't escape not using code fully, but I mean trying to find a route where there is as little of it as possible in order to use Udon prefabs and upload a SDK3 world. I guess I am just worried about trying to comprehend the complexity.

Thank you guys for your help. It's really appreciated.

[light nova]

if anything is required to integrate an item into a world, then it should have that somewhere in its manual/readme/description/info/whatever.

[long stream]

hmm okay, that is a good point. I hope that is the case. I know sometimes the prefabs on booth are hard to understand or don't come with info, but I haven't really downloaded and played with them quite yet. What about how to just setting up a SDK3 and Udon world from the start? I have seen some videos on just what to install for a world but nothing about how to setup the SDK and how to upload the world when ready from unity.

[light nova]

just create an empty project, import World SDK3, open up the Udon example scene, and play around with it. uploading is basically the same as in the case of avatars.

[long stream]

hmm okay! That is helpful. Is there any settings I should make sure to be enabled? I know you need to have like mouth blend shapes, and eyes, height setup at least for avatars... is there something of that equivalent for worlds? Anything that explains theses: video, blog post, etc? :S Thank you again for your help. 🙂

[light nova]

the example world is an example of a working world, so no, nothing more should be needed there.

[dreamy sentinel]

I could use some help with updating Udon Sdk for the first time in a while, I believe everything is imported correctly, but no matter how many times I do clean imports i'm left with these 5 errors

From what I've been able to glean from other comments it might have something to do with vrchat being in a different drive?

[dreamy sentinel]

fixed it

[floral dove]

What was the issue?

[dreamy sentinel]

Found someone else with the problem by searching up some keywords in discord, they solved it by starting up vrchat and downloading something it prompts you too (it didn't appear for me until closing out of vrchat and vrchat ran fine without it, I was joining worlds fine)

that little standard windows vrchat prompt, i forget what the download was called (i remember it's descriptor was about joining worlds off of links or something)

now to work on my old ass project and try to understand wth it was doing and how to make it work

and how to modernize it with all the new udon updates

Oh I also updated cinemachine through the package manager

[bleak echo]

Trying to take an array of game objects and toggle them all off. How do I change their states all at once?

[grand temple]

make a for loop to go through the array one at a time

[bleak echo]

thought there might be a shortcut, ok, I'm attempting that.

I think this should be it...

I suppose that with UNU this is the sort of thing that should be updated manually.

[grand temple]

yeah you've got all the variables plugged in but you're missing the white line flow to the gameobject setactive

[bleak echo]

I should connect it to the for loop, correct?

[grand temple]

yeah, the "body" output

[bleak echo]

yes

ok, got it

[grand temple]

yep

[bleak echo]

thank you so much!

[tacit harness]

I need to get a random bool value can someone tell me how to do that ?

or get that

if yes pls dm or ping me

[ivory steppe]

Can we make it so an object pool spawns every object in the pool straight away?

[ivory steppe]

I'm looking for the same thing but I'm not sure it exists...

[tacit harness]

It is probably possible somehow as you can definitely get a random number but i just dont know how to conver that to bool

I have been googling for so long but nothing

[ivory steppe]

Yeah I'm trying to add a randomized element to my object pool (a deck of cards) however I'm just simply not able to find anything on how to do it

So I feel your pain

[tacit harness]

qwq

[dreamy sentinel]

ugh, this slider just won't sync, and I don't see how it is functionally different from the one in the example

[limpid trout]

Well I don't know anything about udon, but in the above example the value of uislider is transferred over a getfunction to the setfunction.

In the bottom example the instance of the slider is transferred directly to the setvalue function.

Only visual this seems to be the difference

[dreamy sentinel]

That's how they have it on their youtube example

[cold raft]

It seems fine to me at first glance. but i have to admit i also got some weird sync problems myzelf that "should work"
one thing you can try is adding Debug.Log to the OnDeserialisation and then check in the console log to see if the deserialisation took place, this is atleast what i notice on my problem that the serialisation never seems to happen

[dreamy sentinel]

ill try that

hmmm serialization failed for slider

caught argumentexception: don't know how to encode slider

[grand temple]

disable "sync" on the slider variable

you can't sync references to objects

[dreamy sentinel]

hmm still giving me the same error

[grand temple]

what variables are you trying to sync?

the only thing that should matter is slidervalue

[dreamy sentinel]

actually it might be slightly different, it's now saying serialization failed for slidersync

also the only variable synced in the graph is the value

now at least

slidersync is the name of the udon graph

and the slider itself

[cold raft]

and i assume its a float value?

[dreamy sentinel]

yup

I'll show the inspector view too in case there's something there i missed
