udon-general

[scarlet lake]

trying some ways but or everyone get teleported (the one that lefted too)

or no one at all

[mossy thunder]

i don't know how to read udon yet. where in your code is it checking if the player being checked is the player who left the collider?

[scarlet lake]

it is the method, OnPlayerTriggerExit(player)

it comes with the player that left the box collider

[mossy thunder]

i could be misreading what it's doing but it seems to me you would want an if else with the triggering player in the if side doing nothing and the other players in the else side doing the teleporting?

[scarlet lake]

the problem is more like this one

if (players[i] != null && players[i] == Networking.LocalPlayer) SendCustomEventDelayedFrames("OnGameFinishTeleport", 1);

since I remove the player from the array when they left

it seems like that it doesn't enter in that state

at all

[coarse parrot]

You could just teleport LocalPlayer to the player who exited the trigger. Do you need extra condition?

[mossy thunder]

i'm wondering are you trying to get the pool down to 1 or detect the first one to leave? on thinking about it i assume the latter otherwise it seems pointless to manipulate the array.

[scarlet lake]

the pool in the end will have only 1 player, and I want it to teleport him away

if (players[i] != null) player.TeleportTo(respawnPoint.position, respawnPoint.rotation);

I think this should work maybe

[coarse parrot]

Teleporting works only on LocalPlayer btw

[mossy thunder]

ahh so a last man standing kind of situation. yeah gonna want to shrink the array then...can you output the contents of the variable to some kind of dev console to confirm the array slot and the variable match?

that's the only reason i could think that it's not properly nulling it out.

[scarlet lake]

I think i get the array empty before it happen since

[coarse parrot]

Ok I see. If you have an array of player who is in the trigger, you can use System.Array.IndexOf method to get an index of player containing in the array. If player doesn't exists in the array, the index will be -1

[scarlet lake]

ye and I think the array is like empty in that moment

An exception occurred during EXTERN to 'VRCSDKBaseVRCPlayerApi.__TeleportTo__UnityEngineVector3_UnityEngineQuaternion__SystemVoid'.

mhm

[coarse parrot]

Should see detail on another line too

[scarlet lake]

Runtime error detected, but the client has not been launched with '--enable-udon-debug-logging' so the error cannot be traced. Add the argument to your client startup and try again.
[UdonBehaviour] An exception occurred during Udon execution, this UdonBehaviour will be halted.

this is the ful

full*

[coarse parrot]

Whatever calling TeleportTo doesn't have value assigned

[mossy thunder]

oo i'm prolly gonna wanna figure out where to add that command to.

question. in udon are arrays' .length value or whatever it is in udon dependant on FILLED slots or LAST filled slot? like if i have an array Fu[] where I've put "Bar" in slot 55 but haven't put anything else in it would it be listed as a size of 55 or of 1?

[scarlet lake]

ok that error

was something else, a little mistake that I did while I was changing something

[coarse parrot]

The .Length is a defined array length regardless of members are assigned or not

[scarlet lake]

it doesn't matter with the teleport at the end

[mossy thunder]

...so it would show as 55 then?

[coarse parrot]

Yes

[mossy thunder]

damn...so then for my use case i think i'll hafta itterate through the array's 10 possible slots checking if they are null while incrementing a variable then use that in place of the length...

[scarlet lake]

it would be nice to use Lists and LinQ but I guess we can't

[mossy thunder]

i seem to recall some methodology in c where you could check the length of an array both ways...don't recall how that worked but it'd be cool if every language had it. 😛

hrm maybe that was sizeof vs length? i can't remember what either does honestly...gah 10 years without using a language is seriously detrimental...

[coarse parrot]

That's the same as .Length

[mossy thunder]

erm? i'm either super confused or i think you misread what i said since from what you said before .Length has one type of output and i was describing remembering c having 2 types of output.

[coarse parrot]

What could be the second type? Like counting member that isn't null?

[mossy thunder]

yeah

coulda sworn i already said as much.

[coarse parrot]

There isn't any function that does that out of box either in C or C++. You still need to add condition and filter the non-null member and count it.

[mossy thunder]

hrm musta had a lib that i always used that had that functionality then...

[coarse parrot]

Could be that

[mossy thunder]

i remember using that functionality for a card game simulator i made. i could remove cards from teh deck by nulling them out and then the deck count just knew without any loops(at least not in my main code) how big the deck still was...

i'm guessing the library basically just used a loop to check all the slots though.

[coarse parrot]

Internally it is. It's just easier just calling one function.

[scarlet lake]

test 2, the last person that goes out of the box collider

get teleported

😩

[mossy thunder]

what's the purpose of the teleporting? is it like moving on tot he next round?

[scarlet lake]

it's like returning to the lobby after the game

or he would be like alone there

[mossy thunder]

i'm confused then why it's bad that everyone gets teleported...

[scarlet lake]

no it's bad that who is still in

[wind atlas]

What happens if the last person also goes outside the collider?

[scarlet lake]

doesn't get teleported

[wind atlas]

Maybe your count just start at 0?

[scarlet lake]

ye it start at 0

[wind atlas]

So you have to do count < 1

[scarlet lake]

mhm

let's tr

try

it didn't work

the last person is still in and the game didn't got

resetted either this time

[wind atlas]

The last player will never leave, so it never triggers OnTriggerExit.

[mossy thunder]

ok these variables and arrays are confusing me...so when you interact with an object it controls variable data in that script...then to access that variable data you peak at it from another script...which makes it seem SUPER complicated how i'm supposed to have a bunch of "join game" buttons around my table that store the player id of the person sitting at that spot on the table...

[scarlet lake]

how can I make him leave when the game end?

it's like the solution is close but maybe i'm just tired XD

[scarlet lake]

that sound like there is alot work to do, something similar to the billiards tables?

[wind atlas]

Scratch my last comment, I was wrong. It will trigger for the other players, so your code should work.

[scarlet lake]

maybe is because i'm trying it in testing so

I have 2 times my account as player?

[mossy thunder]

i guess that each join game button stores to a variable not an array, then the "start game" button peaks at all those scripts to build an array for it's own usage then all the other scripts peak at that button's script in turn?

[wind atlas]

Maybe the issue is somewhere else in the code, for example when you put the players into the array.

[wind atlas]

The player instances are still different, even if you use Build and Test.

[scarlet lake]

I see

[mossy thunder]

i'm wanting to do something kinda like that i guess. i'm making resistance (the board game) and rather than having to shuffle cards and then secretly hand them out and have everyone secretly check them i figured i could automate it sorta like how the amongus server does.

[scarlet lake]

there is something wrong in that way of saving the players in the array?🤔

[wind atlas]

That should work. Are you displaying the counter? If not, you could try doing that in the canvas, maybe you see the issue this way.

[mossy thunder]

well like the way i'd do it anywhere else there would be an array that just exists that i could put data into from anywhere else int he program. so to me it's very weird that i have to constantly be cross referencing scripts...

[mossy thunder]

"when in doubt spam the heck outa debug messages!" 😛

[wind atlas]

Yeah, debug.log it.

[scarlet lake]

tried to use Debug.LogError("Messages")

but I can't see them on unity

[wind atlas]

You should be able to press "RShift + Backtick + 3" to see them. Or enable logging in UdonSharp if it's not on.

[mossy thunder]

i usually prefer runtime debugging. instead of having a log somewhere instead my code is displaying all the debug info real time alongside what it's supposed to show. that way i can track every variable at every step to make sure things are changing and getting set the way i expect.

[scarlet lake]

that's probabily the case, that logging in udonsharp is not on

how can I turn it on?

[wind atlas]

Project Settings and then UdonSharp, I think it's called Listen to Client Exceptions

[scarlet lake]

it seem it was already on, time to test again then

[wind atlas]

I'd recommend debug.log(counter) them. Then just "RShift + Backtick + 3" while in Build and Test.

Or make the canvas, I assume you want to have some kind of display for players anyway.

[scarlet lake]

guess so i'll make the canvas

[trail palm]

i guess its somewhat udon related. how can i make pickup objects 2 handed? i want that if you first pick it up, its one handed but then you can grab it again to make it 2 handed

[wind atlas]

Unless there is a solution for VRC somewhere out there, you will have to code that yourself.

It shouldn't be too awfully difficult though, just requires some rotation math.

[mossy thunder]

i imagine there's code to help figure it out int eh pool prefab.

[trail palm]

oh well, ill try but im a bit dumb

[wind atlas]

Try looking for tutorials for regular VR stuff, I'm sure someone must've made one for two handed pickups. You just need to take out the math, and ignore all the SDK specific code.

[wind atlas]

Took me a bit what you meant by pool.

[wind atlas]

Yeah, the pool prefab might have some code for holding the stick with two hands, you could look into that too.

[mossy thunder]

it def does. though the way the pool tables work is a bit unique. once you are holding the que stick there's a glowing bit that you can grab and that's the second handhold. it then pivots around that handhold while the other hand controls distance and is where you derive that pivot from.

[mossy thunder]

ok i must be dumb...how do i store what player pressed the "join game" button?

[wind atlas]

I'm assuming join game event is locally fired? Then you can just use the local player.

[mossy thunder]

i guess? it's an interactive object like used for toggles and the like.

i hit space and searched for local and nothign came up.

oh found it hidden under networking. would be nice if the search could search inside submenus...

[floral dove]

You can use 'tab' instead of 'space' to search through submenus, too

it's slower, which is why we default to filtering by class first with space

[mossy thunder]

what's the datatype of LocalPlayer? i thought it'd be an int but trying to store that in an int didn't work.

[floral dove]

It's a "VRCPlayerApi" object

[mossy thunder]

i see...

[floral dove]

that object does have an int, I think it's playerId

here's more on that class: https://docs.vrchat.com/docs/players

[mossy thunder]

k so in the button's script i'll store that to a variable. then in the "start game" button i'll have an array that looks at all the buttons to get the players that pressed each and get them tied to the right part of the table?

and i'm guessing i'll wanna do a network event so all the data can be colated onto one user...

[mossy thunder]

just realized...this is just going to make it look like the local player is sitting at all of the active table spots...i need to grab it before sending the network event then figure out how to transmit the playerapi right?

[thorn jewel]

As stated it's being moved by its translate function (Transform. Translate (Vector3)). The object itself i tried as part of both the environment layer and interactive layer.

The collider is also very large on the object so it spends a good time intersecting erroneously before fully breaching the wall, due to the slow movement speed.

I'm thinking that translate might not account for physics, but I'm not sure what else to move it with by a set amount.

[floral dove]

I'll translate your graph as best I can:

1. When the local player "Interacts" with this UdonBehaviour, send a NetworkEvent to everyone currently in the world to run the event "ToggleTarget"
2. Every player currently in the world will run "ToggleTarget" locally, which will set their 'PlayerAPI' variable to their own PlayerApi object.
3. Then each player currently in the world will toggle the target GameObject's active state to the opposite of whatever it currently is.

If that's not what you want to do, could you explain what you would like to have happen?

[wind atlas]

Yeah, it just moves the object directly and ignores physics. You'd need to do your movement via a rigidbody or calculate the collision yourself.

[wind atlas]

You could try rigidbody.velocity and feed it your vector3 movement.

[thorn jewel]

Would velocity continue though when input ceases? Or will it have momentum? I was thinking about testing the same but that's my big concern.

[wind atlas]

If you set velocity only once, then it will keep its momentum. That might not necessarily be a problem though.

What specifically are you moving with Translate?

[thorn jewel]

Wheelchair. Was grabbing user input and applying it to "velocity" & "rotation" values, then on Late Update I would multiply those values by Delta Time to move & rotate the chair. Works great if you don't consider the whole clipping through geometry thing.

[wind atlas]

I see, so the one sitting is controlling it? You can just apply that velocity and rotation to the rigidbody and it should be fine. If you do it every frame, then as soon as the player stops giving input, the velocity will be 0.

[thorn jewel]

Yes, and Noted.

[thorn jewel]

While you're here: Is there any special logic a VRCStation with an Udon Behavior needs? I was having trouble getting this working for over an hour the other night, and the only solutions appeared to be either removing the udon controller, or adding this bit of logic:

I'm still new to some of this, so I'm worried this may be incorrect. (It does look similar to an example program though.)

[floral dove]

how does this compare to the example program that shows how to use a station in the UdonExampleScene?

[scarlet lake]

someone can help me with this? I want the player to drop items if he is using some

but ofcourse they can be null

it goes on error on line 76 saying it is null

how can I avoid that error?

[thorn jewel]

I'd have to open up the example scene to be sure, but I looked back over the UdonProgramSources directory under Examples, and found a Station related program (I overlooked) which is nearly identical to depicted; the only difference is its using UseAttachedStation and I'm using UseStation and a station variable.

Though the docs don't really make it clear that station interaction is disabled with Udon Behaviors, which is why I am confused.

[floral dove]

First, I recommend you add a Debug.Log statement between the Interact and the UseStation to ensure that the event is firing

[wind atlas]

Yeah, the example is what I used to see how to do it. I don't remember how the station exactly work of the top of my head.

[thorn jewel]

Can debug information even be viewed on Quest? I don't have a PC to test with. I usually have a friend test my world after the Quest end is stable.

And after adding the behavior, it works, to be clear. It wasn't working without handling Interact.

[floral dove]

You could have the interact change the value of a text field instead of writing a log. The main things is to ensure that the "Interact" event is running. How do you develop without a PC?

[thorn jewel]

I have a Mac.

The docs for VRC_Station make no mention of Udon Behavior requiring additional setup, so I was confused as to why the station was disabled with an Udon Behavior attached. But looking over the example, that seems to be by design.

[floral dove]

Ah, ok. You could use ClientSim to test in the Editor for faster iteration in the future: https://clientsim.docs.vrchat.com/ But to solve this particular issue, you can have the Interact do anything else which will be visible for you - like changing a text field, or toggling another object on/off.

[thorn jewel]

If the station works now, is there a reason to test the interact?

[wind atlas]

I feel like that question is self-explanatory. If you don't have trouble then you probably don't need to test it.

I have a question about VRCObjectSync. It doesn't seem to sync between players when I disable the object during Start.

What could the reason be for that? I could swear it didn't do it before.

[floral dove]

Oh, there's not - I think I misunderstood and thought that you couldn't get it working.

[floral dove]

Re-reading your original post, it sounds like you're asking if a VRCStation needs an UdonBehaviour in order to function. If that is your question, the answer is yes.

[thorn jewel]

Would it be rude to ask why? And why that is seemingly undocumented? I understand that the examples use this, but at the very least, the document page for VRC_Station makes no mention of Udon.

Thank you for pointing me to client sim though; had no idea that was a thing. Will definitely give that a go.

[floral dove]

I agree that the documentation for Stations should be updated to explain how to use them better.

[wind atlas]

So I tried delaying the disabling by a few seconds and now the VRCObjectSync works. Odd, wonder why that happens.

[scarlet lake]

like the teleport one

write something a bit ugly but I don't have really other idea for making people drop things

and this one work

😩

[grand temple]

you can use player.GetPickupInHand(VRC_Pickup.PickupHand.Left) and player.GetPickupInHand(VRC_Pickup.PickupHand.Right)

[scarlet lake]

tried, it goes in exception if that hand is not holding anything

[grand temple]

then check it with utilities.isvalid

[scarlet lake]

as I wrote here it gone in exception in the first line, there is a way to check is valid before

even taking the object?

i'll look into it anyway

[grand temple]

yeah, only do anything with it if it's valid

        if (Utilities.IsValid(RightPickup))
        {
            RightPickup.Drop();
        }```

[scarlet lake]

wait a moment

oh god

it is the local player that make it fail?

in my case i mean ofcourse

since I was not using the local one

[grand temple]

well it's a function you call on the player

so yeah if the player is not valid that would break too

I don't know if getpickupinhand works on remote players but it at least shouldn't crash as long as the player is valid

[scarlet lake]

something like this then

[grand temple]

yep

[grand temple]

I would not recommend using player.isvalid

use utilities.isvalid(player)

player.isvalid will only catch a very unique situation where the player used to be valid but has now left the instance. if the player was simply never valid, like if it was straight up null, then player.isvalid will crash the behaviour

[scarlet lake]

oh didn't know that

i'll change it then

[thorn jewel]

Is there documentation or guidance on how to upgrade an existing project? The instructions say to use the package format versions of the SDKs, but it seems to be colliding with the pre-installed Worlds SDK. (My console had a lot of errors suddenly during import.)

[floral dove]

Sure, that's covered here: https://vcc.docs.vrchat.com/vpm/migrating
However, if you can wait an hour or two, we're about to drop a new version of the Creator Companion with some big changes and upgrades so it's worth holding off for a little bit. (New version will be announced in #creator-companion)

[thorn jewel]

Woops.

Too late. 😅

[floral dove]

Haha no problem. There's just a new migration method in the new version, but it's even simpler so shouldn't be a big deal.

[thorn jewel]

I winged it and treated it like the Avatar SDK during the betas:

• Put under source control
• Make a GIT commit
• Fire Sale: All SDKs must go
• Import the new SDKs and hope Unity doesn't crash
• Crash? Revert to commit.

[floral dove]

that's some big brain work right there

[thorn jewel]

I learned the hard way not to trust anything between Unity & VRC SDKs. So many animator properties, lost to the abyss.

It's big brain, it's messy, but I know nothing will be lost.

[floral dove]

if you're doing a git commit first, then you can use the in-place migration rather than having an extra copy. We warn against doing that for people who don't have backups

[thorn jewel]

In-place migration? If you mean importing the new SDK over the old SDK, that's exactly why I use GIT now.

It might be Mac related, but there's a 50/50 shot migration goes south for the winter.

Causing a bunch of errors related to math, causing the SDK control panel to break, etc.

That's why I started deleting the old SDK first.

And then Unity crashed and removed all SDK related properties from my project.

So now I use GIT to ensure that isn't permanent.

[floral dove]

I mean the option in the Creator Companion to migrate from the legacy .unitypackage system to the new packages system. It offers you the option to migrate a copy or migrate in-place. We highly recommend migrating a copy unless you're 100% sure you have a backup of your project.

[thorn jewel]

OOOoh I get you.

Is the creator companion out? I'm sorry if I'm out of the loop on things. I just look at the docs, which tend to fall behind.

[floral dove]

It's currently in an Open Beta

[thorn jewel]

I may hold off trying it for now. Unity did not like the package form of the SDK base.

(Complaints about lack of various types in System namespaces, such as "immutable")
Restarting it seems to be doing something.

[scarlet lake]

after i drop a object with VRCPickup.Drop

there is a way to respawn it?

i mean how can I take the VRCSyncObject for respawning it?

[floral dove]

You need to use the Creator Companion to install the new SDKs. Not sure how you pulled them in but if you did anything besides using the CreatorCompanion or adding the proper git URLs yourself then they will not work.

[floral dove]

grab a reference to it before you drop it

[thorn jewel]

I did the proper GIT URLs

It looks to be doing something now though.

I think it just had cached parts of the old SDK that hadn't yet refreshed.

It gave me some new prompts on relaunch.

Though my console is still filled with errors.

[scarlet lake]

you mean I put the gameobject as var in the code, in the code from the gameobject I take out VRCPickup and VRCObjectSync?

[floral dove]

Ok - I'd still recommend using the CreatorCompanion instead since that will actually remove the existing SDKs and add the new ones. But like I said, new version coming soon that switches from git to embedded packages so best to wait a few hours to a day at least.

[thorn jewel]

Is there a link to the companion?

[floral dove]

Sure, that sounds like it could work

[floral dove]

Sure, it's on the page here: https://vrchat.com/home/download/sdk

[thorn jewel]

Oh so it is. Don't recall seeing that last I looked.

Thanks.

[scarlet lake]

now that I think about it, the object is thowable so, doing a box collider for the player

feels useless

[thorn jewel]

Uh momo that's an EXE

I use Mac

[floral dove]

Ah right. There is some preliminary support for Mac and Linux through the CLI: https://vcc.docs.vrchat.com/vpm/cli

[thorn jewel]

I think I'll stick to the unitypackage version of the SDK for now and forgo the client sim.

I don't mind having to publish and test.

Beats headaches caused by upgrading SDKs.

[floral dove]

Alrighty, I understand. Good luck with your project!

[thorn jewel]

(I had 400+ errors with the GIT packages)

[scarlet lake]

if I do a box collider, there is a way to write if the object goes outside of the box collider, respawn

?

[topaz jetty]

that happens when you have both the unity package and the git installed

create a backup of your project and then remove all unity package sdk folders and then add the git urls

or just use the migrate button in the creator companion which does it for you

[thorn jewel]

That's what I did.

[topaz jetty]

did you try to migrate in the creator companion too?

[thorn jewel]

We just established that the creator companion isn't readily available for Mac.

There's a CLI version, but that's a bit of a headache to go through the trouble for just to test my world in unity.

[topaz jetty]

ooh yeah sorry didn't see it

I mean cli shouldn't be that hard right? You only have to add and then migrate

would probably just be like 2 commands

though I haven't used it yet

[thorn jewel]

I'd have to install the .NET 6 SDK, and I've already spent a considerable amount of time already futzing with this. I also have limited drive space, and a lot of SDKs like .NET insist on being on the system drive as opposed to external.

[topaz jetty]

ah ok understandable

[thorn jewel]

So I'd rather just wait for now, maybe try it down the road.

[topaz jetty]

just curious, why isn't the normal creator companion not for mac/linux? Isn't it made in unity? It has the unity crash handler in it's program folder

[valid oar]

Yeah, OnTriggerExit, teleport to the location of the spawn object. https://www.youtube.com/watch?v=BheVIHD3Vrg

[thorn jewel]

BTW there were errors when I messed up the first time and this happened, but not 400+ of them, and they were conflicting namespace errors.

When I deleted the old SDK first and then installed the GIT versions (after a git restore), it was complaining about basic classes and namespaces not being found in system classes.

I'm thinking the package versions might not be fully tested on Mac? Either that or something about my project structure and Unity's weird caching is causing me yet another issue.

[scarlet lake]

that work for objects too? not just players'

?

[topaz jetty]

did you install the base package aswell? The git packages are split into base, world and avatar and for worlds you need base and worlds and for avatars you need base and avatars

[floral dove]

1. The CreatorCompanion does a number of Windows-specific things like finding Unity Windows and bringing them to the foreground, etc.
2. Windows is currently the preferred development platform for VRChat and the only platform that receives full support. We'll do our best not to break our SDK for Mac and Linux users, but we're concentrating our efforts on the vast majority of our creators who are using Windows.

[valid oar]

Sorry for the trigger, OnTriggerExit should work, this video is what you need for object respawn https://www.youtube.com/watch?v=p6vtL_BRMEo

[floral dove]

Creator Companion discussions are best held in #creator-companion, and you'll need to follow the instructions for your platform to get a project migrated to the new system.

[topaz jetty]

if it's just that shouldn't it just be a few if statements to add mac & linux support? I understand that vrc only supports windows though but some people only own a quest & a mac I guess

[thorn jewel]

Thank you. Wasn't sure if this was appropriate to continue here, but was a bit shy to ask.

[scarlet lake]

thanks for the info i'll look into them now

i'm a bit confused about OnTriggerExit

there isn't any override of that one

[topaz jetty]

you can also use cyanemu https://github.com/CyanLaser/CyanEmu btw, it's the unity package client sim is based on. It has slightly less features but it's still better than having to build & publish every time you want to test a small thing

[scarlet lake]

it should be something like this?

[valid oar]

Maybe? It should just be like the video has it but OnTriggerExit instead of Interact but I haven't done that sort of thing myself.

[scarlet lake]

well just tried it

and it work

so it was that one

[scarlet lake]

udonscript is failing to compile somewhere?

[simple heron]

i dont know

i get 1 red thingy

from my chess board

[valid oar]

You might want to try removing that and see if you have any issues, at least it would narrow it down.

[simple heron]

ok its def my chessboard

literally says

failed to compile after that error

now i have no chess

:C

[valid oar]

I'm not familiar with that particular asset, but making sure Udon Sharp is installed would be the first thing and then just consult the documentation if there is any.

[simple heron]

Ok

[white fractal]

how do u split a vector into 3 floats

like UE BP lets u split a vector 3 to have 3 seprate pins for each value in a vector 3

how do u do that in udon

[grand temple]

vector3 get x

vector3 get y

vector3 get z

[white fractal]

whats the setter called for it

[grand temple]

vector3 set x

[white fractal]

is it set

[mossy thunder]

As I said in that message I want it to trnasmit the PlayerApi variable to everyone online (and to any new connectors the way i am with toggle states)

[simple heron]

vrc pedestal isn’t click able

[floral dove]

The VRCPlayerApi object cannot be synced across the network, so you'll need to try another approach like syncing the id. Why do you want everyone else to have the PlayerApi variable?

[simple heron]

momo help :<

[floral dove]

Try the one from the UdonExampleScene

[simple heron]

Im trying the prefab one

[mossy thunder]

when i say i want it synced i don't mean that object necissarily but some way of agregating the full list of players of have joined the game and at what table slot they did.

[floral dove]

Are you running in Build & Test? Can you provide a few more details?

[simple heron]

no im uploading my world

I just cant click it

[mossy thunder]

i imagine if i could even figure out how to transmit the id in the object then i could then look it up in the array function i create later.

[floral dove]

Ok, you can assign someone as the 'owner' of all the information and update a playerId variable on them instead, always check with them for the logic of player-to-tableslot

[simple heron]

In my world the pedestal isn’t intractable

[mossy thunder]

...momo it's much appreciated that you are helping, however you are misunderstanding my struggle. honestly your suggestion here is something i already considered. my issue is that i have not found the graph entity i need to transmit anything other than event data. well that's the issue i have at this very moment...

[simple heron]

:0

Wait the udon scene one works

Why doesn’t the prefab one?

[floral dove]

your options for networking are Events or Synced Variables. Maybe this information will help: https://docs.vrchat.com/docs/udon-networking

[floral dove]

compare the differences between the two for their Udon Programs and their variables in the inspector, as well as their layers and colliders.

[simple heron]

Im an idiot but i’ll try

…

Everything seems the exact same

[mossy thunder]

... ok i'm so friggen dumb... i read that last night and couldn't figure out how to sync varaibles but you don't ever transmit it you just check synced...no idea how i overlooked that...must have been WAY to tired.

ok now the issue i've realized is if i'm going to be syncing an int instead...i need to find the graph entity that lets me grab that data out of the PlayerAPI entity.

basically the equive of varID = PlayerApi.ID i'm guessing.

hrm do they not have ids?

oh duh they probably do but not as a data piece but as their index in the array...so...i'm going to need to itterate through the array?

[rocky lantern]

is there a way to get the direction a player is looking?

[mossy thunder]

i could be very dumb but wouldn't GetRotation be that?

[floral dove]

what outputs do you see on the node for the VRCPlayerApi object?

[mossy thunder]

... and i just found get player ID... JFC..i swear i did a space, playerapi, id and nothing came up...

[floral dove]

Yeah, it can be helpful to just lay down the object first so you can see its fields and their types

[mossy thunder]

oh wait... is what i found...is that not right? cause i didn't find a dedicated VRCPlayerApi object.

[floral dove]

That's correct, you'll need to feed a VRCPlayerApi instance into it to get the player id out

[mossy thunder]

having this before the network event will do that though, no?

ok. so i have the join/leave button configured to store the user that clicks it. i'll need to also set it to have a way to null it out if the player leaves. then i need to create a similar button for taking hosting privileges, then i can use the host buttons to agregate all this data into something useable in the game...

[mossy thunder]

ok something i'm confused about for the toggles it looks like using one script for the whole group works fine but it looks like when you go to peek at variables inside a script you can only do it from the overall script not from a specific instance of it...so should i be having a different script for every button in my script?

[thorn jewel]

It seems velocity is not the thing I'm needing. The chair barely moves at all, and I also seem to get some "unspecified" behavior where it continues to drift slowly.

I am going to try something else though, and will report back if it works. If you or anyone else has any ideas on how to "translate" an object with physics, let me know.

[wind atlas]

It sounds like you might be applying deltaTime to it. If that's the case, try removing that. Rigidbodies run during FixedUpdate and don't require deltaTime, so the velocity might be too small to have much effect.

[thorn jewel]

Oh I was. I didn't realize that, oops.

[thorn jewel]

Do you know how to fix the object "bouncing" around, picking up momentum, etc.?
Nevermind, I think I understood "Freeze Rotation" lol.

[thorn jewel]

So yea no removing delta time didn't seem to change it. I found a method that works though, it's just a few extra steps. (Using MovePosition and some math on the existing position)

[thorn jewel]

Is there a way to trigger the VRC input window and in-game client's on screen keyboard (on Quest, particularly). I've seen some video players do this, but the built in example does not. I didn't change anything about the input window, functionally, yet click and nothing happens. It registers the selection, visually, but no input window appears.

I've seen worlds trigger the input window on video players, so surely I'm doing something wrong?

[mossy thunder]

can someone verify if each button should have it's own script file instead of just using the same script file when i want to be able to use the variables for each button separately? I'd rather fix that before i get too deep in this.

[dawn forge]

I have a script that represents a button on the keypad. I just use a integer variable to tell my master script what digit they pressed and for reset or enter, I just use two bools isReset, isEnter

[mossy thunder]

i'm not sure how i'd derive this with my graphs as they are set now. right now i just have the graph dragged onto 10 buttons and it does it's toggle stuff just fine but that's because i set the target toggle in the button's inspector not anywhere in the script...

[dawn forge]

I'm on the go but i reference my master script and call _ApplyDigit(int n) or if isReset, _OnReset(). And it goes on from there. My 1-9 and reset/enter is the same script behavior, just each button object has a instance of the script

[mossy thunder]

i'm guessing if i am having the script get variables (like who pressed which button) then this instanced aproach might get trickier than just having separate script files?

my final usecase is that there will be 10 buttons to join the game, each of the up to 10 players will click a different join button and then the button will disapear from everyone preventing anyone else form joining the same number (until the player who already has it clicks the leave button or the host will probably have a force clear option for if someone d/cs) then i need to have an array of which players hit which join button so the right info shows to the spys vs the resistance.

[dawn forge]

Ok so a single script can achieve this. On interact, grab the vrc player's display name and store it in a variable so that button remembers the player.

Then you can .setactive the button behavior to false to hide it.

Oh and vrc object pool will help a lot since you're wanting to manage these buttons as a collection

[mossy thunder]

1. wouldn't player id be better than display name? 2) won't the second button pressed overwrite the stored value in the variable?

[dawn forge]

Player ID is fine, either or display names have to be unique.

And no. When you have a button hold an iantance of a script, it only affects itself. They don't share a same instance at all.

[mossy thunder]

one question this gives me, is player id comperable with the index of the player in the world's players array?

[mossy thunder]

ahh so then when another script looks at that variable you are able to tell it which instance of the script you want to peek at then?

[dawn forge]

Worlds player arrays? You have to build that yourself. You ultimately rely on the vrcplayerapi https://docs.vrchat.com/docs/getting-players

[mossy thunder]

ahh i assumed somewhere the world was keeping an array with all the logged in players and their 3d location indexed most likely by order of join. and that you could then refference this array(actually assumed that's what vrcplayerapi was doing.

[dawn forge]

Exactly, you reference all buttons in another script and read its variables granted you made it public accessible

[dawn forge]

Yeah VRCPlayerApi[] is your gateway to all player and transform data that vrc permits you to interact with. Let me forward you something I do to track my players and their own data.

This. Sorry I can't express it in graph but I am using an object pool to hold objects that runs my player scripts that holds data about the player. Typically a copied object of vrcplayerapi.

You can do the same for a button, but you'd do it for interact and pull Networking.localowner vrcplayerapi object to your button.

I'm mobile right now so my example is approxinate. For your button graph, create a vrcplayerapi variable and player name. You can't sync vrcplayerapi object itself, so we will depend on the player name to be your key index.

On the button graph, on interact, take ownership of the object, set the vrcplayerapi with networking.localplayer and set your playername with .displayname from your vrcplayerapi object.

Now your button will remember the person who interacted with it, and you'll need to sync playername so others will see this reflection.

Now you're ready to call each button and enumerate its values.

[winter gazelle]

I'm having an issue with Raycasting

I have my origin and direction determined by the head rotation of the player

but when using the debug draw rays I cant see them

i set the color and opacity

[wicked forum]

What's the state of struct support in U#? It seems to have let me create one but I can't do anything with it

[indigo finch]

You can't play videos in the inspector. you'll need to 'build and test' to test this

what error messages is it giving in game? (Rshift + ` + 3)

[scarlet lake]

there is a way to change TextMeshPro Text in code? since I can't find TextMeshPro reference

nvm solved

[shy osprey]

how do I set a public UdonBehavior variable to another script? i cant drag anything into it unlike other public variables

[scarlet lake]

I did it like that

for putting another script inside another one

[shy osprey]

do you know if theres a way to do that in the graph?

[scarlet lake]

I'm sorry I don't know, I'm quite new so I didn't used a graph yet

[shy osprey]

ah alright, thanks for the help anyways!

[indigo finch]

yea, it should bring up a debug console. make sure you are using the Right Shift + BackTick + 3, and not any other keys

[arctic scarab]

how i detect analog button pressss

[mossy thunder]

is there a way to open multiple graphs?

[dawn forge]

Is there anything about axis events for input nodes? I can't look because I'm on the go but see if there is an event for axis key press

[dawn forge]

Not that I know of, would be a nice feature

[arctic scarab]

of course not

[mossy thunder]

i feel like the very most frustrating thing about unity is the way that it seems like no 2 of the same thing can ever be open at once...which makes copying bits from one thing to another rather painful.

[winter gazelle]

I need a way to take a Euler rotation value and turn it into Direction value

[grand temple]

convert it to a quaternion then multiply that quaternion by vector3.forward

[winter gazelle]

so take the quaternion x, y, and z values and multiply each of them then construct a vector 3 to get the directions for all 3 in one vector?

or just multiply the WHOLE quatenion with a Vector3.forward

[grand temple]

the whole thing

never split apart a quaternion into it's individual xyzw, it's going to be nonsense

[winter gazelle]

oki

Thank you

[winter gazelle]

I think my VRCPlayerAPI isnt working

Cause I have a Start event that checks a bool thats updated based on the IsinVR node

then it gives a message in the Debug log

i got no message

works in unity but not in game

[grand temple]

Udon breaks when you have multiple execution lines flowing into one node like this

[winter gazelle]

I'll remove that but I added that after i noticed my stuff not showing up in the ingame debug

This debug is supposed to give me my head position, rotation on keypress of Keypad 0

along with another message sayingit was pressed

this does not show up ingame

nor does my debug ray draw

[shy osprey]

bump

[dawn forge]

Setprogramvariable

[shy osprey]

do i put that in the script thats calling the behavior or the behavior itself?

[grand temple]

Try recompiling your scripts. Are you sure you're dragging in an object with an udonbehaviour though?

[grand temple]

Check your log to see if the udonbehaviour is halting?

[winter gazelle]

nope

[winter gazelle]

It's not halting

[scarlet lake]

I do not know why but this does not work I wanted the player to teleport when I click door.

[winter gazelle]

VRCPlayerAPI.TeleportTo is what youre looking for

[scarlet lake]

Ah I see. Thanks!

[shy osprey]

getting this error when trying to get an object from an array, the array has 9 objects and im trying to call object 0

[dawn forge]

You're calling an index that is not defined, is the element defined in the array?

That or you're calling an index outside of 0-8

[winter gazelle]

None of my dbug logs are showing up in the ingame logs

so i cant tell whats broken

it works in unity

not ingame

[shy osprey]

i set every 'get' node int in the graph to 0 and it still got that error, so it cant be that

it might be some issue with the system i have to convert a pool into the array

[winter gazelle]

@grand temple I got the exception from the log this time

[dawn forge]

Looks like it's trying to get the game object of a collider, and is failing to do so. Is collidervariable setup with a value or instantiated?

[winter gazelle]

I ended up removing that whole gameobject stuff

Now it takes the collider and gets the coponent i need

So when the ray fails to get a collider its empty

And when it find one without the coponent it doesnt do anything

[grand temple]

You need to check if the collider is valid before trying to do something with it

[winter gazelle]

did that earlier after being suggested

thank you so much for the help

[vapid badger]

Hello, if I'm using UdonSharp instead of the graph, are my questions suited for this channel or should I go to #world-development ?

[valid oar]

You're good, all Udon is allowed here.

[vapid badger]

Thank you. I have sliders that I can adjust in-world to change parameters of game object components... When I tested it a few weeks ago, a guest was also able to use the sliders, but they only affected his perspective locally. Is there a way to have sliders that only I can control? (I guess "I" would be the Game Master, ie. the person who first made the instance, or the next in-line after that one leaves - if my understanding is correct)

ie. I'd want it so guests can't even change the parameters locally.

[indigo finch]

so you want a change you make to apply to everyone, but you don't want them to be able to make any changes?

[vapid badger]

@indigo finch Yes, is that possible?

[indigo finch]

certainly. you would need to make a synced float variable, then whenever your slider value changes, make it update this sync variable. A synced variable can only be changed by the owner of the object, which will default to the instance owner. Then you just need to make it so that when that float variable changes, it updates the value for the slider, which can be easily done with a property.
Also, add a little bit of logic so that when the slider changes, but the person isn't the owner, it corrects itself to the synced float value

[vapid badger]

@indigo finch Thank you! Is this the correct syntax for a "synced float variable"?

[UdonSynced] public float poo;

[indigo finch]

yup, though it doesn't need to be public ^^

[vapid badger]

right

@indigo finch What's the c# syntax for checking if someone's the owner?

[indigo finch]

Believe it's 'Networking.LocalPlayer.IsOwner(gameObject)'

[vapid badger]

@indigo finch I'll try that out, thank you. So I'd put the slider's gameObject as the argument.

[indigo finch]

sorry, I'm more use to udon graph, so all my coding repertoire is kinda lacking...

Might be kinda basic, but I'm a little lost as to what you mean

[vapid badger]

Oh, you sounded like you knew what you were doing til now! 😄

[indigo finch]

I know what I'm doing, just not how it's normally said 😅

[vapid badger]

@indigo finch for the (gameObject), you'd put the slider in those parantheses, is what I meant.

[indigo finch]

it would be whatever object the script is on, thus 'gameObject'. We want to know the owner of the script that has the synced float on it

[vapid badger]

ohhh, I see. Got it!

[indigo finch]

btw, slight correction to what I said before, but you only need Networking.IsOwner(gameObject) instead of Networking.LocalPlayer.IsOwner(gameObject)

[vapid badger]

@indigo finch Do you mean something like this? I tried to follow your instructions, but unsure of how to use a property here:

oh, I can move that first line outside of the foreach loop

[indigo finch]

To fact check what I was saying, I made this example:

also made it for graph XD

[vapid badger]

ah, so FieldChangeCallback is an Udon-specific property?

and wow, you're going all out. xD

oh, my bad. the property's at the bottom

[indigo finch]

I'll probably make a video covering how to sync a slider value, as it's not an uncommon thing for people to ask, so I figured I might as well make an example for me to come back to later

[vapid badger]

actually, maybe there already is one? You answered me before I watched it ^^; https://www.youtube.com/watch?v=ecu9oaUxClI&ab_channel=VRChat

though he shows how to do it with the graph, not c#/u#

[indigo finch]

Neat, good to hear there is something out there (not always the case). This video is with old udon though, before they added the 'onVariableChanged' events. They also didn't cover how to take ownership of the slider so that anyone can change it's values. Still, it does cover a bunch of good stuff ^^

[vapid badger]

@indigo finch What happens if I leave out the line "mySlider.value = sliderValue"?

Wouldn't it be fine, since the SliderValue property is set from mySlider.value to begin with, and only when the owner is accessing it?

and what does the FieldChangeCallback do here? It sounds like it'd be an auto-generated property.

[indigo finch]

perhaps you could add a 'isOwner' check, but that line of code will update the slider value for everyone else, when the synced float changes

[vapid badger]

ahh, I see!

[indigo finch]

I'll be honest, I don't know its origin or anything, other than that is the thing that you do to get the equivalent of 'onVariableChanged' event nodes found in graph

if you look it up, would love to hear what you find ^^

[vapid badger]

there's no obvious definition page when you Google "udon FieldChangeCallback"

[dawn forge]

I found this for it while ago. https://github.com/MerlinVR/UdonSharp/wiki/UdonSharp#fieldchangecallback

When do you think we will see support for lambda expressions and predicates? I use those a ton at my work and I feel like doing my enumerations to search my arrays is pretty punishing to the game.

Disappointingly, Array.Exists, .Contains is not exposed.

[vapid badger]

@dawn forge Ah, thank you! So it looks like it shouldn't be a necessary attribute if you never try to set the field directly, right?

@indigo finch And your code worked, thank you!

[dawn forge]

That's correct, I barely use it unless I am syncing manual fields. synced fields doesn't need this attribute either, but this paradigm is fantastic to have your code short and clear instead of checking if the value has changed every OnDeserialization.

[scarlet lake]

there is a command line that tells me if the localplayer

is on quest or pc?
