@icy gale - hm, not sure if that's related to the known cache issue in this latest patch. You might try re-uploading your world as it seems to be failing a blueprint match.

icy gale Aug 31, 2020, 12:28 AM

i've tried that a few times, someone on reddit said to delete vrcsdk and reimport it

#

are public synced variables object based? like if i have an udon behavior with a synced variable, and 2 objects that use that udon behavior, are the references to the public variables on the respective objects unique?

fiery yoke Aug 31, 2020, 12:51 AM

#

Yes

#

Two UdonBehaviour's can run the same program, but they are still seperate instances

daring copper Aug 31, 2020, 12:51 AM

#

cool, thanks

fiery yoke Aug 31, 2020, 1:09 AM

Sort of. It hasnt been "adjusted" to work with SDK3 particularly. But there still is some functionality

How do I clear the test-build cache? It keeps loading up an old test I built hours ago regardless of which unity project I have open. Or is there something wrong with the servers or such?

fiery yoke Aug 31, 2020, 1:17 AM

#

@normal sable Yeah its currently a bug. Delete the "Unity", "VRCHTTPCache", "Cache-WindowsPlayer" and "Cookies" folder in "C:\Users\YOUR_USER_NAME\AppData\LocalLow\VRChat\vrchat"

For spookality, are you supposed to fill out the submission form before making the world or after?
Also, with the VRChat username. Are you supposed to put in the username you can change or the one you can't?

Does anyone know where I could get all the controller rotation offsets? I am trying to use the hand tracking data but as it is right now it is useless as it apparently is different for each controller (index, vive wands etc.). Ideally I'd like to have the rotation/position of the laser pointer which is both avatar and controller independent...

dense halo Aug 31, 2020, 12:19 PM

#

Can you have a dynamic array as a public variable in an udon sharp script? Such as an array of gameobjects?

tropic canyon Aug 31, 2020, 12:22 PM

#

@dense halo what do you mean by dynamic array?

#

@native fern use pickups, maybe

native fern Aug 31, 2020, 12:24 PM

#

sadly that is not an option for me, i want the user to press all the buttons on the controllers at the same time... which will make them drop the pickup if I used them

dense halo Aug 31, 2020, 12:26 PM

#

@tropic canyon as in an array that can be changed in size.. So you can add in as many references to game objects as you want in a list. Rather than saying there are "5" game objects, you make it dynamic and you don't have to define how many, and you want you can keep adding them.

tropic canyon Aug 31, 2020, 12:27 PM

#

List's aren't available atm

#

but you can store any predetermined size

#

so if you initialize it with 5 things and you want to add another you need to initiliaze a new array of gameobjects of size 6 and copy the first 5 from the old array

#

(being quite slow)

native fern Aug 31, 2020, 12:39 PM

#

U# example for array size increasing:


        // increase the length of the _targetsIds array by 1
        var targetCount = _targetIds.Length;        // get the current array length
        var newIds = new int[targetCount + 1];       // create a new empty array that is longer (!)
        _targetIds.CopyTo(newIds, 0);               // copy the old array elements to the new array (starting at index 0 in the new array)
        _targetIds = newIds;                        // replace the current array with the longer one, has a new ('empty') array element in the end

dense halo Aug 31, 2020, 1:58 PM

#

Yes, but you can't have that as a public variable,. so you'd be able to add in the GameObjects through unity, without it being set as a static array.

#

Plus that leads to a lot of memory allocation.

#

Actually you can't even define public static arrays as variable for UdonSharp to use can you?

native fern Aug 31, 2020, 2:34 PM

#

it works with both public and private arrays...

#

static is atm not possible

#

only catch with public ones is, they usually get initialized with the length 0

#

I am using them quite frequently, the only thing that can be problematic in my experience so far is doing this every update with many large arrays

#

it is easier/more performant to keep track of the number elements inside it and have empty space in the end rather then reallocating every time you add/remove an element

#

basically oversizing a bit

#

depends on what you need or how you use it

dense halo Aug 31, 2020, 2:59 PM

#

What I mean is to be accessed here.

#

📎 unknown.png

native fern Aug 31, 2020, 3:23 PM

#

you would just do public GameObject[] interactableObjects; for that... In the editor you see a 0 afterwards. When you set it to something >0 you get to see the elements like in your picture...

#

you can 'resize' this array at will at runtime using the shown method

the editor will treat it as a list so you can just drag it onto the missiles thing and it'll add it to the array

dense halo Aug 31, 2020, 4:45 PM

#

@native fern OOhhhh THanks! I think it was there the whole time when I was testing, my dumbass just couldn't see it.

#

What's the best wait to setup a wait function?

#

As "UdonSharp does not currently support node type YieldReturnStatement"

#

Or is it better to just use a fake timer on update?

hearty linden Aug 31, 2020, 5:04 PM

#

Is making a ping pong table with working networking physics something that's viable with Udon in VRChat? I have a setup that feels good when I test alone. Physics seem to work well. But when I tried it with another user the physics seemed to get wonky. Was only able to multiuser test it once though and I had a few friends in the test world at the time.

native fern Aug 31, 2020, 5:11 PM

#

@dense halo np, for now you have to use one of the update methods to implement waiting. I tend to store the start time and check how much time elapsed. When it is longer then my wait duration I call another method that does whatever i want. I prefer it over adding deltatime to a variable and checking that against the wait duration...

#

@hearty linden make it a rather big table or tennis I guess... the issue is that you will always see the ball fly past the other player and suddenly it will teleport back to the player and come towards you again due to constant ownership transfer and network delay

fiery yoke Aug 31, 2020, 5:15 PM

#

VRChat is relatively bad when it comes to latency. Its around 200 milliseconds at all times.

native fern Aug 31, 2020, 5:16 PM

#

in the eu it is upwards of 600ms total

hearty linden Aug 31, 2020, 5:16 PM

I thought it might be something like that. bummer

fiery yoke Aug 31, 2020, 5:16 PM

Which in itself isnt too bad, but without any lag compensation its noticable.

#

Yeah when I was testing with a friend the ball seemed to float around a bit randomly.

#

Maybe I can figure out how to make a single player version. Though don't think I would be able to figure out making even a simple ai player

native fern Aug 31, 2020, 5:23 PM

you can make a wall that the ball can simply bounce off of

like in real table tennis training

hearty linden Aug 31, 2020, 5:29 PM

Does VRChat have plans to get the latency into more reasonable numbers eventually? Is it on the roadmap or is it just inherent?

I have a graph that is supposed to teleport a list of pickups, with a synced position, to a set position on an interact event. However, it seems that it only items that player1 picks up will get teleported on interact, not objects that player2 picked up. I thought that this may have been an ownership thing like synced variables but setting the network owner of the object didn't change the behavior. I'm not sure how to fix this issue

@bleak widget it's definitely an ownership issue, but simply changing ownership immediately before setting position won't fix it because it takes a moment before the ownership transfer can complete. I would recommend either waiting for half a second after taking ownership or sending a network event so that everyone in the instance moves the objects so they whoever is the owner will get it done

@brittle zealot - if you're comfortable with C# development, then I recommend you read the gettings started docs here to get your environment all set up: https://docs.vrchat.com/docs/getting-started-with-udon
Then install UdonSharp: https://github.com/MerlinVR/UdonSharp
FYI UdonSharp is not officially created nor supported by VRChat, but I have no qualms recommending it.

brittle zealot Aug 31, 2020, 9:06 PM

Oh, there's a way to use actual code, nice! 👍

#

Thanks, I'll take a look at those

floral dove Aug 31, 2020, 9:08 PM

#

Yep - the graph is great for beginners who are not ready to write code by hand, but a C# programmer will probably find it quicker to pick up U#, which uses C# syntax to compile Udon-Compatible code. Just remember that it's not full C# / .NET, you have to work within the sandbox of Udon.

Another question: I've loaded up the SDK with the example project.

Neither scene is in Unity's Build Index. How can I change what scene it builds?

Is udon its own scripting thing?

I got into a AP Computer science class and i wanna know if this would help me learn more about udon for my world

errant pilot Sep 1, 2020, 11:50 AM

#

Udon is its own computer language @idle aurora . Its still in the works, but most code is written itself compared to using nodes. Unless you want to program using assembly, which is difficult, you should stick with the graph or us U#, which is a C# compiler for Udon

idle aurora Sep 1, 2020, 11:51 AM

I have no clue what you just said so im gonna assume that this class might help

oh btw

how do i like use Udon to start?

#

Like do i have to import a package to my world?

errant pilot Sep 1, 2020, 12:03 PM

Only the VRCSDK3 package

And programming background wont hurt you in learning udon, its just a different language mean different ways of it functioning

Does screen space overlay UI work in udon or do people use something else?
Also, what do people do to change the environment. Is it just teleport + destroy?

errant pilot Sep 1, 2020, 12:58 PM

#

@idle aurora importing any package does not effect the world at all. And its best to import it before you start building. But importing it after wont make any difference

#

@scarlet lake Yes a world space canvas works with Udon. Just be sure to add the vrc ui shape component if you have buttons on it. And what do you want to change the enviroment? Lots of options with udon

I mean i have uploaded this world multiple times

#

I havent threw in the sdk3

#

but yes im sure thats the sdk2 (no idea)

idle aurora Sep 1, 2020, 3:02 PM

#

So am i just screwed or...

#

Can I not update my world to SDK3 If its already got an SDK?

errant pilot Sep 1, 2020, 3:48 PM

#

@idle aurora Well SDK2 is not at all compatible with SDK3 so you can't update it to udon, you have to make a new project for that to work. If it is an earlier version of SDK3, then you have to delete it from your project first, then import it

idle aurora Sep 1, 2020, 3:54 PM

#

damn that actually sucks

#

theres no alternative?

dense halo Sep 1, 2020, 4:47 PM

#

When I move an object that has interaction scripts on them, I seem to be unable to click them after they've moved.
Lastly how does, "IsPlayerGrounded" work?

fiery yoke Sep 1, 2020, 4:49 PM

#

What exactly do you mean with move? Move in the scene? Or move them in the hierarchy?
IsPlayerGrounded tells you if the player is grounded :P I think its a CapsuleCast or SphereCast, but could be any other method as well. Definitely not just a raycast straight down tho, since that wouldnt work.

Alright I have a question, udon graph is compiling "OK" however the public variables aren't exposing themselves. It's refusing to let me see the variables and change their values.

I have tried:

Restarting the editor
Removing udon behavior from object and reattaching the script
Deleting the problematic variable and recreating
Duplicating the udon graph
Deleting graph and rebuilding
Deleting Library folder

and so far haven't gotten it. No public variables are exposing regardless of the type. Only started today when I opened the project.

#

nevermind. After deleting the Library folder I just had to copy the entire graph, delete all the nodes, and then paste them back in

idle aurora Sep 1, 2020, 5:08 PM

#

Can I just transfer my project to a new project like my buildings and everything but transfer it without a SDK

#

put in the SKD3

#

Then transfer my project to that?

severe tree Sep 1, 2020, 5:12 PM

#

As long as you remove all the old scripts from SDK2 you can port everything as is from the old project

#

so if you have objects that toggled or were pickups for example, if you remove the scripts from them then you can just port all the assets (aside from the SDK) and then port the scene to the new project

idle aurora Sep 1, 2020, 5:14 PM

#

I never did anything with scripts

#

i dont know anything about em lol

#

I know triggers like 1 trigger

severe tree Sep 1, 2020, 5:14 PM

#

So you never had any toggles or pickups or anything like that?

idle aurora Sep 1, 2020, 5:14 PM

#

Here

#

Yes I can pick up somethings

#

And I can hover over a item and it says a text

#

Like this

#

📎 unknown.png

#

you can pick these up

severe tree Sep 1, 2020, 5:15 PM

#

Anything that made it work with SDK2 you'll need to remove the components for. So all the objects that you can pickup you'll need to remove the Pickup component and etc...

idle aurora Sep 1, 2020, 5:15 PM

#

these paper have a text when you hover over it

📎 unknown.png

#

So pretty much all Triggers?

severe tree Sep 1, 2020, 5:16 PM

#

All the triggers that use something from the SDK somehow

#

Like you don't need to remove the colliders, but all the VRChat components will need to be removed

idle aurora Sep 1, 2020, 5:16 PM

#

Okay...

#

I think get what you mean

severe tree Sep 1, 2020, 5:16 PM

#

Once you remove them all you can port it to udon easily enough

idle aurora Sep 1, 2020, 5:17 PM

#

So just remove ALL triggers

#

I dont have any seats or mirrors either

severe tree Sep 1, 2020, 5:20 PM

#

pretty much yep. Once all that's gone and you port it into a new poject that has SDK3 it should all be ready to be added back through Udon instead.

idle aurora Sep 1, 2020, 5:25 PM

#

do you mind calling me and teaching me incase?

#

Im super sorry but I just dont feel confident to do that on my own

@fiery yoke

When I change the object with the interaction script's transform, specifically it's Y, I don't seem to be able to click to interact afterwards.
I've tested using it and it doesn't seem to work as I expect. I stand still in my world, and it continues to give false back, saying the player is not grounded....

fiery yoke Sep 1, 2020, 11:06 PM

#

Well I know a way to do it in UdonSharp

#

but I have no clue how that works in the graph

#

you can just have a generic array of objects

#

and then cast them to UdonBehaviours

severe tree Sep 1, 2020, 11:08 PM

Yeah I haven't looked at UdonSharp yet, not very familiar with C# so figured that the graph would be easier but that's about the only thing I've run into that's got me beat at the moment lmao

In the log it says "Object reference not set to an instance of an object"

and it gives you two parameter adresses: 05 and 1A
05 is the Text component itself. 1A is the string you want to set the text to.
05 is null. Therefor your UIText variable is not set to a component

@idle aurora most of the basic stuff you'll need can be found as prefabs in VRChat Examples Ranging from buttons, Pedestals, Mirrors and more. If you want to see how they work and such, you can load up UdonExampleScene scene that can be found there as well

Most of it, you don't need to know coding, like, I know zero coding

That's what prefabs are for lol

https://booth.pm/en/search/VRCSDK3 You can a decent amount of free prefabs here, if you don't mind translating pages and stuff.
Some of it requires Udon C# imported which you can get here > https://github.com/MerlinVR/UdonSharp/releases

#

The main downside of booth, besides the obvious difference in language is, stuff that contain words, will most likely be Japanese, and will require translating strings which if not done right, cause errors, like my issue I was having here > https://discordapp.com/channels/189511567539306508/657394772603830360/750708843415339058

@scarlet lake sounds like somethings off with your hierarchy. Check the way your Pedestal is setup up compared to the one in UdonExampleScene. Also, please don't post the same thing to multiple channels 🙂

oh right you have to have the stuff in order

i shall remember also duplicate post removed

all of the added components are now in the right place it looks identical to the first version and i used the avatar pedestal prefab program and it still showing the picture of the avatar way out from the pedistal and huge

#

do i have to littraly make the program from scratch

floral dove Sep 2, 2020, 5:17 PM

there are no differences in scale and position between the objects in your pedestal and the example version?

hmmmm

i mean the mesh i made is not at the same scale as the orignal pedistal

so im thinking maybe thats a problem

oh i dont know

#

its littraly my first day with this

lol

floral dove Sep 2, 2020, 5:24 PM

No problem, we all start somewhere. It sounds like the issue is not in the program but in the scaling and offset of your items.

how do i set that 🙂

i mean can i change that in the program

You can change the scale and position of your items using the hierarchy. If you're new to Unity, a video like this might help: https://www.youtube.com/watch?v=8pC3SE5PIzY

I'm currently watching some tutorials on Udon scripting since I'm at work and can't try em out, but is it possible to use ScriptableObjects to define things in a world? Like if I want different guns with different fire rates and things, can I store that data in an SO and attach those to my Udon script, or would it not be able to expose those fields?

#

Like, if I had a U# script with public GunSO gunData, could I drag in an asset from the file system into that?

Hi folks! Hopefully this is the right area for this - I'm an indie gamedev moderately familiar with Unity and C#, but brand new to VRChat stuff, and I'm looking to work with AI (namely, NavMesh stuff) in VRChat - I see that the associated components are whitelisted and I'm hoping someone might be able to help me out
Before I get too far in, I've heard its possible to modify the player controller so that it doesn't have all the issues (or at least minimizes them) associated with Rigidbody-based controllers, does anyone have some documentation on any of this stuff? Ideally I'd like to use a NavAgent.Move-based controller, as I'm looking to make a Game World that involves the player losing control (and regaining it) to an AI and that would circumvent some other issues I've thought about

@blissful wigeon The player controller is close to untouchable. There is some janky methods of circumventing it or making your own entirely, but most if not all of those methods have some drawback.

You can set the transform.position of the object to where the parent is at

sterile pumice Sep 3, 2020, 2:41 PM

#

yea but I can only get that to work for 1

tropic canyon Sep 3, 2020, 2:44 PM

#

you can get all child transforms by iterating through them

#

so a for loop from 0 up to parentTransform.ChildCount and in it you do a "parentTransform.getChild(index).position"

dense halo Sep 3, 2020, 3:58 PM

#

Any idea how I'd create a "slider" interaction like a volume bar.
I can obviously create the bar, but I'm not sure how to create an object that can be grabbed, and moved, but is locked to x and y for example, and limited in z between 0 and 0.1.

#

I tried making a pickup object that was frozen in certain dimensions but I think I'm going down the wrong path.

fiery yoke Sep 3, 2020, 4:01 PM

#

@dense halo Mostly maths. I made a "physical UI system", but Im not quite finished with it just yet.
Some useful functions are Mathf.Clamp and Vector3.Project

dense halo Sep 3, 2020, 4:05 PM

#

@fiery yoke Thanks for the info,. so how would I limit an objects transform? Just on update if it's position.Z > 0.1, position.z = 0.1?

#

Or would I have to implement my own modified "VRC pickup script"

fiery yoke Sep 3, 2020, 4:11 PM

#

Ohh you cant really restrict a pickup. The pickup would just be a proxy for your hand position

#

Its a little complicated

dense halo Sep 3, 2020, 4:12 PM

#

Ah okay understood!

#

Thanks

fiery yoke Sep 3, 2020, 4:12 PM

#

For example here is a simple lever that is restricted

📎 VlVTSLNjb0.mp4

dense halo Sep 3, 2020, 4:12 PM

#

That helps so much otherwise I would be lost down the wrong route.

#

I'll just grab the hand position then using GetTracking, and proxy it,.

fiery yoke Sep 3, 2020, 4:13 PM

#

Well there is some considerations to be made

#

especially with local vs world based position

#

Most of that stuff is Vector Maths

dense halo Sep 3, 2020, 4:14 PM

#

Oh don't worry I know all about that.

sterile pumice Sep 3, 2020, 4:44 PM

#

Thanks @tropic canyon figured it out from what you said pretty much.

#

all I had to do was add a few things to my graph and it worked

dense halo Sep 3, 2020, 5:09 PM

#

Is there any way to determine if an "Interaction" (object with interact) is being held down instead of clicked once?

dark tiger Sep 3, 2020, 5:24 PM

#

Is there a way to constraint an object to the player's position? (maybe other than on update move the object to the player's position :p)

errant pilot Sep 3, 2020, 5:27 PM

#

Id presume the player is not holding it? @dark tiger

#

And thats a good question @dense halo

dark tiger Sep 3, 2020, 5:28 PM

#

@errant pilot, Yes. Without making the player hold it

errant pilot Sep 3, 2020, 5:32 PM

#

Without update, im unsure

dark tiger Sep 3, 2020, 5:40 PM

Ok, thanks

#

Can you play animations through udon?

#

I have an animation clip reference but I don't see any options to "play" it.

dense halo Sep 3, 2020, 6:26 PM

#

As udon doesn't support "Animation" components.

errant pilot Sep 3, 2020, 6:37 PM

#

I think you can reference an animation controller, and have the controller do the rest

floral dove Sep 3, 2020, 8:37 PM

you can trigger animators

I saw in a world they had this text field box thingy where people could type and send them a message, I was wondering where I could get that and how it works. Not sure if it sends them a message to discord, a bot, or what ever it could be

#

Actually, i'll go and find it and screenshot it

#

ib4 it says where on the box and i didnt see it

fiery yoke Sep 4, 2020, 11:42 AM

#

@scarlet lake Pretty sure that "abuses" Video Players. Video Players basically send a HTTP Get Request to whatever address you enter. They then have a custom server setup at that address, which takes the argument and processes it and sends that to a Discord Bot which then posts it as a message.

#

Because of that, Video Players have temporarily been disabled.

scarlet lake Sep 4, 2020, 11:44 AM

#

I see, so that will never ever exist on UDON, got it lmao

fiery yoke Sep 4, 2020, 11:45 AM

#

Probably not

#

Unless they intentionally give us the ability to do something like that. Which is unlikely, since it isnt really controllable

scarlet lake Sep 4, 2020, 11:45 AM

Thought it would be extremely useful for people who don't want random discord friend requests to report bugs or issues and have it tunneled through that

Well anything that lets you send arbitrary data, to arbitrary addresses, from inside VRChat, is a big security concern.

scarlet lake Sep 4, 2020, 11:50 AM

#

I understand that

#

But what's a security concern when tons of security in vrchat is bypass able 🤷‍♂️

Like photon bots

fiery yoke Sep 4, 2020, 11:51 AM

#

That is not directly "security"

#

thats just stability

scarlet lake Sep 4, 2020, 11:52 AM

#

they enter public worlds and crash everyone (or a target) and leave.

Or desync bots that cause the entire world to run like you're at 6000 ping

or mesh crashers that place 2000+ meshes on their avatar, and crash you unless you have them fully hidden

fiery yoke Sep 4, 2020, 11:52 AM

#

Yeah that is just stability.

#

They disrupt you or the vrchat servers. But thats not security. Security has to do mostly with protecting user data and the integrity of program flow.

scarlet lake Sep 4, 2020, 11:53 AM

Understandable. I just look at those as flaws then I guess. Wish they could be patched, especially those stupid bots

#

Does anyone know if there is a more efficient way for waiting some specified time (in seconds, or even minutes, maybe) without making the program sum up the time every frame with Update?

#

I am afraid of overusing Update in my programs :p

fiery yoke Sep 4, 2020, 4:34 PM

#

For waiting you have to.

#

But you can minizime the effort

#

Dont count up by adding, but compare the current time to an "end time" which you set at some point to the current time + offset

Ok soo i have very weird problem.. I have object that i teleport around the world.. (Portable board for player to interact with) When i teleport it to player it ends up being wrongly rotated.. Nothing wrong on that.. But when i try to rotate it by ANY value of x y or z it flips it weirdly always.. The SAME script worked on different world perfectly FINE..

In here ⏫ I am rotating x y and z by 0.1 always.. Even tried smaller values but always same

Made it input stuff into debug

After x rotated by 0.1..

Anyone any ideas why its doing what its doing ?

Hey y'all, is it possible to get data persistence using Udon? Even if it's just a few bytes.
Also how would I copy to clipboard using Udon?

floral dove Sep 5, 2020, 1:14 AM

#

Not on VRChat's servers. You can have your users highlight something in a text field and press Ctrl+C to copy to clipboard.

#

That's how some people do persistence like the roller coaster building world

fiery yoke Sep 5, 2020, 1:15 AM

Would be neat if VRChat had a way to Copy to Clipboard / Paste from Clipboard easily in VR (especially for Video Players 👀)

Ah I see. Thanks Momo.

I hear that. You don't want apps reading your clipboard without your permission, but maybe there's a way we could do that safely

#

No not from within VRChat

#

Basically just have something like a Macro I guess

#

I guess it would be from within the Client then

#

Hmm I mean you would still have to navigate to a site

#

so that wouldnt help at all then.

I guess its an issue you cant get around easily. Virtual Desktops help with that already I guess.

How can I get inputs from two different triggers in one node graph? Currently the trigger is on the object which has the udon behavior and it seems to just know that it should use the collider trigger on itself...

Is there some way I can tell the On Trigger Enter node which trigger I want it to activate from?

Or some way I can forward a trigger event from a different object into the existing graph?

#

Well, I was able to get that to work fine on the non-beta, but I didn't try the controller part. I am not sure exactly what you are attempting, but I'm probably just too new to this.

#

Are you trying to access variables from gameobjects on the node graph?

#

Let me see if I can make it work. I haven't tried yet.

#

Okay, I got it working.

#

I don't know if it's the best way, but it works.

#

@rocky scarab

📎 unknown.png

#

TeleportPoint is a gameobject I placed at the destination, and then dragged onto the graph.

#

The node search thing is a little confusing, because they are nested.

#

And the naming doesn't always match what the node titles say in the graph.

#

To get local player, first search for networking

#

And then go into the SDKNetworkingBase thing or whatever it is called, then in there you can search get local player.

#

It kind of is, yes. I think it's because there would be too many results, and maybe even there could be loops in the graph of how all those different nodes are interconnected.

#

So as confusing as it is, it might actually be the right way for it to be.

#

Or maybe it is just confusing for no good reason xD

floral dove Sep 5, 2020, 10:24 AM

#

@rocky scarab you can press Tab to get the all-in-one search. Learn all about how to search through nodes here: https://docs.vrchat.com/docs/searching-for-nodes

echo coral Sep 5, 2020, 10:25 AM

#

Thanks @floral dove ! I didn't know how to do the tab thing yet ^_^

#

I had a problem like that when I think I closed Unity while it was doing something. I had to close unity, reopen unity, and then right click the assets and reimport all.

#

Then it all worked fine.

#

hmm

#

That didn't cause any problems for me.

#

Oh, there is a thing where sometimes when you drag stuff onto the graph it doesn't always have it connected right.

#

But if you go to the object with the udon behavior it has shows the list of variables you added.

#

And then you can drag the gameobject onto the variable input thing that has the same name.

#

Yes, the button is the object I added the udon behavior to.

#

And it also had a collider set to trigger mode.

#

Which is how that interact node gets it's input magically without needing another thing feeding it in the graph.

#

@floral dove Is there a way to specify the trigger you want to register the interact from? Or does it have to be the trigger on the same gameobject as teh udon behavior?

#

Have you made a world in SDK2?

floral dove Sep 5, 2020, 10:39 AM

#

Interact fires on the object you Interact with, you can then use a reference to another object from the first one.

#

@rocky scarab if you're new to world creation, check out the UdonExampleScene and the Readme in the VRChat Examples folder, it goes over a lot of basic programs and how they work.

echo coral Sep 5, 2020, 10:42 AM

#

So, if I wanted, I could have one ubergraph for a particular system in the world, and all the ways that different parts of that system could be altered could be events forwarded from objects with triggers?

#

So, in a way, that main graph can be a persistent object that tracks the current state of that one entire system?

#

And if so, how do I forward the events from the various triggers?

#

Trying to imagine that graph as an object with methods that can be subgraphs in there, and variables that can be accessed from any of those methods.

#

Awesome!

Hey guys, I was wondering if it is possible for a world to force an animation on a player

is using sdk3 /udon a good idea even for a standard world?

drowsy terrace Sep 5, 2020, 1:43 PM

#

I'm trying to make a modular-ish system for doors & levers/buttons.
I've made a door prefab that triggers open/close animations depending on a boolean, and would like to make a lever prefab that can open/close a referenced door prefab. How could/should I do that? In C# I'd add a door variable to the lever and change it's status boolean when interacted with but I can't manage to get how to do that with Udon... any idea?

prisma abyss Sep 5, 2020, 2:01 PM

Let's say this Udon Graph should activated/works when the gameobject with this udon is active (from disenable state). What do you think? Does it work too with Animator animation?

I have a very long object that i want to be able to pickup from both ends. The VRChat docs say something about: "Physical Root - Can be used if the root of the object is not on the same gameobject as this script, allows for multiple pickup points on a single object." But I can't find anymore info. I don't see that option and I tried putting the script farther down the layers, based on what I thought it might mean, but I can't get it. What am I missing?

Assets\lightworld.cs(14,11): System.NotSupportedException: Udon does not support variables of type 'PostProcessVolume'

floral dove Sep 5, 2020, 5:20 PM

@dusty bane the quickest way to reload is to go to your VRChat control panel, turn on advanced settings, then you can run your Last Build from Build & Test instead of needing to re-build it.

dusty bane Sep 5, 2020, 5:20 PM

@versed rapids - you can't directly manipulate a PostProcessVolume with Udon.

(please mention me if you reply)

flint urchin Sep 6, 2020, 12:26 AM

@echo coral we can’t use C# as is. Even with U#.

But if you want to make sure the door only closes when the last person leave, update a int value and only close the door when it’s 0

How can I override the sitting pose of a station/chair in an Udon world? I am trying to make a chair where players sit on the ground with crossed legs.
Disclosure: I have never done this in a non-Udon world either.

#

I was going to just use the AFK animation for the sitting idle animation.

#

But I don't know how to apply it correctly to the Udon sample chair in a way where it works.

#

Since Avatars 3.0 and Udon Worlds are separate, are there things I need from the Avatars package or even the SDK2 avatar stuff in order to have a base animation controller to override?

(I am not smart when it comes to avatar-related things, all my unity knowledge so far has been for worlds)

#

Does anyone have a preferred currently best way to keep track of all players in the world? I understand you can't get the full player list currently because lists are not a thing? So you need to maintain your own array of some kind to track the players in when the join or leave?

floral dove Sep 6, 2020, 3:00 PM

#

@echo coral you can use VRCPlayerApi.GetAllPlayers

fiery yoke Sep 6, 2020, 3:01 PM

#

@floral dove Is that in live already? or open-beta?

floral dove Sep 6, 2020, 3:01 PM

#

That was added to live about a month ago

fiery yoke Sep 6, 2020, 3:02 PM

#

Jeez. I really havent done anything with Players in a while

echo coral Sep 6, 2020, 3:09 PM

#

Does anyone have a snippet of working U# code that uses VRCPlayerApi.GetAllPlayers ?

floral dove Sep 6, 2020, 3:15 PM

#

@echo coral I'm on mobile right now but all you have to do is make an array big enough to hold the max players you can have in your world and then pass that into the function call.

fiery yoke Sep 6, 2020, 3:17 PM

#

For UdonSharp related questions you should probably ask in Merlins Discord. But here

private VRCPlayerApi[] players = new VRCPlayerApi[81];

void OnPlayerJoined(VRCPlayerApi player)
{
  VRCPlayerApi.GetPlayers(players);
}

#

that might work

floral dove Sep 6, 2020, 3:18 PM

#

Ah yes, it's just called GetPlayers. Thanks @fiery yoke

echo coral Sep 6, 2020, 7:42 PM

#

@floral dove That worked for me to get the player list. However, I am checking the list and using player.GetPosition() for non-null entries, and I have a problem where when someone leaves the world, their entry is still in the list, is not set to null, and I can even get the name parameter from it... but GetPosition() throws a nullpointer Udon VM exception when it is called on those entries, and I don't know what object it is trying to reference so I can detect it before the call to GetPosition. I thought maybe there was a race condition, so I have a counter and only run the code to get all that stuff once every 90 ticks of Update(), and it still happens. Even when I reload the player list right before looping over it.

How can I identify stale entries in the player list?

#

Perhaps I just need to set the entire array to nulls each time I re-call the GetPlayers method so it is a fresh place for it to put stuff?

#

It just feels odd because you have to pass the array in to GetPlayers for it to put the info in, so it seems like it should be responsible for keeping it in order. If it could only be called on a fresh array each time, why pass it in and not just have it always return a new one?

fiery yoke Sep 6, 2020, 7:55 PM

#

@echo coral When creating an array the Runtime has to allocate memory for that array. When the last array is not referenced anymore the Garbage Collector has to deallocate that memory again. It creates unnessecary work. So its in your hands to allocate the array and then reuse it like that.

echo coral Sep 6, 2020, 7:56 PM

#

So when a player leaves the world I should find their entry in the array and manually set it to null?

fiery yoke Sep 6, 2020, 7:56 PM

#

No just do the same OnPlayerLeft

#

Just refresh the array whenever a player joins or leaves

echo coral Sep 6, 2020, 7:57 PM

#

I do

fiery yoke Sep 6, 2020, 7:57 PM

#

Then the PlayerApi shouldnt be in the array anymore.

echo coral Sep 6, 2020, 7:57 PM

#

That is why it is confusing that there is still some stale data accessable in there.

fiery yoke Sep 6, 2020, 7:57 PM

#

Otherwise I would consider that a bug

echo coral Sep 6, 2020, 7:57 PM

#

I kind of feel the same, which is why I'm asking about it.

#

However, I also accept that I am extremely new to this.

fiery yoke Sep 6, 2020, 7:58 PM

#

I havent used that method yet, so I cant really say

echo coral Sep 6, 2020, 7:58 PM

#

So I am mostly waiting for someone to tell me how I messed up ^_^

floral dove Sep 6, 2020, 8:07 PM

#

@echo coral if you've got a reproducible bug, please file the graph on Canny.

#

You might try just calling GetPlayers any time you want to access the data instead of On Players leaving or joining.

echo coral Sep 6, 2020, 8:12 PM

#

I am now actually, but I am passing in the same player array as the first time. And it seems to be leaving stale data in it.

floral dove Sep 6, 2020, 8:12 PM

#

You are correct that you shouldn't have to manage the array yourself after the initial construction, since you pass it along each time. The actual Player list is managed internally by VRChat and copied into your array each call

echo coral Sep 6, 2020, 8:12 PM

#

I think it's only copying the number of elements of actual current players over to my list.

serene moat Sep 6, 2020, 8:12 PM

#

Are you only looping to the number of players?

floral dove Sep 6, 2020, 8:12 PM

#

But if the new player list is smaller than the old one, you'll have stale entries, yes

serene moat Sep 6, 2020, 8:13 PM

#

yeah

#

get the player count at the same time and only loop over that number of players

echo coral Sep 6, 2020, 8:13 PM

#

ahh

#

That makes sense ^_^

#

I was looping over the entire thing and only processing the ones that were not null

#

So any time it updates it will always put the current players in the lowest elements of teh array?

#

So if the player in element zero left, that would be replaced with a different player that was still there?

serene moat Sep 6, 2020, 8:15 PM

#

yes that's how it should work

echo coral Sep 6, 2020, 8:15 PM

#

okay ^_^

fiery yoke Sep 6, 2020, 8:15 PM

#

Its essentially taking the list of players and putting them in your array

echo coral Sep 6, 2020, 8:16 PM

#

Thank you all for the explanation! ^_^

#

Slight less noob every day :p

#

One thing though, what method is there to call to get the current player count? Or do I need to maintain that myself by inc/dec a counter in my OnPlayerJoined and OnPlayerLeft methods?

floral dove Sep 6, 2020, 8:21 PM

#

Look at what else is available in VRCPlayerApi

echo coral Sep 6, 2020, 8:23 PM

#

I was looking on the reference doc html and didn't immediately see an obvious one there, but maybe I am looking in the wrong place.

lilac hatch Sep 6, 2020, 8:23 PM

#

Ahm, any informations on why having the latest beta SDK (i didn't try on the normal one yet ;w;) turn off the Realtime Global Illumination everytime I hit play ? seem to be off in game aswell :T

#

SDK2 doesn't do that.

serene moat Sep 6, 2020, 8:24 PM

#

🤔 I am able to use realtime GI on SDK3

lilac hatch Sep 6, 2020, 8:24 PM

#

I just tried to remove the SDK3 from the project and it do not turn off anymore, I'm a bit lost.

serene moat Sep 6, 2020, 8:24 PM

#

do you have Bakery in the project?

lilac hatch Sep 6, 2020, 8:24 PM

#

Yep, using it.

serene moat Sep 6, 2020, 8:24 PM

#

Bakery will force realtime GI off

#

which I've seen cause that problem for other people

lilac hatch Sep 6, 2020, 8:25 PM

#

Does not do that on SDK2 tho, use the combine with enlighten real-time GI setting

#

and the moment i remove the beta SDK3 it stay on when I hit play :(

serene moat Sep 6, 2020, 8:25 PM

#

🤷 make sure that setting is still enabled

#

I just used realtime GI in an SDK3 world yesterday with video players

lilac hatch Sep 6, 2020, 8:26 PM

#

That's exactly what i'm trying to do :(

serene moat Sep 6, 2020, 8:28 PM

#

is your GI set on enlighten and not the progressive lightmapper? Did you bake with Bakery after setting that? The only thing I think the VRCSDK touches is the auto generate lightmap setting

#

which should be off

lilac hatch Sep 6, 2020, 8:30 PM

#

It is, I did aswell. I'll re-import now that I baked and the GI seem to stay on.. after my league game

#

I don't really understand tbf

echo coral Sep 6, 2020, 8:31 PM

#

@floral dove I found it using the node search. Perhaps those HTML docs are not up to date?

floral dove Sep 6, 2020, 8:31 PM

#

@echo coral perhaps.

#

Node Search / IDE search is usually fastest

serene moat Sep 6, 2020, 8:31 PM

#

if Unity decides that your bake isn't up to date and auto generate is on, it will generate the realtime lightmaps. If the VRCSDK disables the auto generate lightmap setting then Unity will just not let realtime GI work until you rebake

echo coral Sep 6, 2020, 8:31 PM

#

Well, everything works swimmingly now, so thank you much ^_^

serene moat Sep 6, 2020, 8:33 PM

#

at least that's what I've seen in some cases

lilac hatch Sep 6, 2020, 9:04 PM

#

reimported the SDK, still does it
I even took the time to re-bake just to be extra sure.

serene moat Sep 6, 2020, 9:05 PM

#

not sure what to say there, I did exactly what you are doing with Bakery and combine with realtime GI and it worked yesterday

#

is your problem that the emissive from the screen doesn't update?

lilac hatch Sep 6, 2020, 9:06 PM

#

I mean, that's what i'm trying to archive, but for that to be working i'll need the realtime GI to be ON in the first place :/

serene moat Sep 6, 2020, 9:08 PM

#

what do your lighting settings look like?

#

you can also just try deleting the Bakery installation once GI is baked, you've verified that realtime GI is enabled, that auto generate lightmaps is off, and that the project is saved. If the SDK is messing with it then might still change back.

#

usually when it comes down to the realtime GI setting being screwed with, it means Bakery has the wrong idea of what you want because some settings are wrong or corrupt. So deleting Bakery rules it out usually.

lilac hatch Sep 6, 2020, 9:25 PM

#

I tried to reinstall bakery aswell just in case

#

I'll try to delete bakery and check after my game https://cdn.discordapp.com/emojis/602434368086081558.gif?v=1

ok so here my problem. i know it probable got ask a million time already but i try to make a Udon teleporter where i have to interact with a gem to arrive on a platform but i have a hard time knowing how to find stuff in udon

i look at a video but he only show the graph not how he make it

https://www.youtube.com/watch?v=vPPpFokmS-Y&t=42s&ab_channel=VowganVR

floral dove Sep 6, 2020, 9:38 PM

#

my approach would be: put an UdonBehaviour on the gem with a graph that has an Interact node that triggers a VRCPlayerApi.TeleportTo call on the player. You can make a variable for the target platform arrival point to easily get its position and rotation in your graph.

solar wolf Sep 6, 2020, 9:44 PM

so 1: i put a udon graph on my gem, 2: i make a interact node and connect it to a VRCPlayerApi.TeleportTo got it, but how do i make a target variable?

Ohh but you can just tell the UdonBehaviour to grab the sliders value by doing an UdonBehaviour.SendCustomEvent in the OnValueChanged method

You gotta remember that UdonBehaviours dont have such "methods". The U# stuff is just an illusion. So you have to do those workarounds.

floral dove Sep 7, 2020, 6:40 PM

#

@sour wind you can see some examples of Syncing variables in the UdonExampleScene and the Readme.pdf that are provided with the SDK in VRChat Examples

#

@rocky scarab - UdonSharp doesn't magically turn C# into Udon, but it allows you to write scripts using C# syntax. For enemy "AI" behavior, learning about NavMesh will help you understand how to make enemies that can seek the player and traverse your world to get to them.

#

However, there's a lot of other logic in programming enemies that you'll need in order to make them react intelligently.

#

hi guys question, what exactly is network synced when it comes to udon?

#

i would like to play a sound effect for all players in a map when a particular script is ran, how would I go about doing this?

#

i'm having it come alongside an animation that plays, but animation sync hasnt been released yet, has it?

#

cuz if animation sync actually is around I'd just have it play it at the start of the animation easy as that

fiery yoke Sep 7, 2020, 11:08 PM

#

Synced is short for Synchronised, which originally meant that two things happen at the same time, but in networking usually means that they "do the same thing".
If you have a variable in a program, and you run that program on two different computers, then there is no way that changing the variable on one computer would also change it on the other computer. In order for it to change on the other computer, they need to be synchronised over the network i.e. Internet.

In Udon you have synced variables, which are constantly synced so that all clients should see the same value, and Networked Events, which means that the event will be called on all clients. Thats what you would use for a Sound Effect that should be played for all players.

#

In Udon that is done via the SendCustomNetworkEvent method/node

restive badge Sep 7, 2020, 11:09 PM

#

so then any of the code ran within that method will run on all clients?

fiery yoke Sep 7, 2020, 11:09 PM

#

Yes

#

with the natural delay that comes by sending stuff over the internet

restive badge Sep 7, 2020, 11:10 PM

#

so if i run a networkevent to all clients to activate the animation to rise the platform and play the sound effect, will it be mostly in sync? I mean it doesn't have to be perfect just close enough

fiery yoke Sep 7, 2020, 11:11 PM

#

Well, because Player Positions and the position of your object are synced differently, it will look like some players would float up earlier, and some would lag behind.
But if thats acceptable, then yes.

restive badge Sep 7, 2020, 11:11 PM

#

that's completely acceptable thanks

prisma abyss Sep 7, 2020, 11:51 PM

#

And wow..... the bug is still there and not fixed. https://feedback.vrchat.com/vrchat-udon-closed-alpha-bugs/p/523-onenable-only-fires-the-second-time-an-object-is-enabled

#

I wasted hours to fix problem.. Yes many hoooooours and i got feeling Udon is bugged. And i was right, someone noticed it and reported, but it was never fixed.

#

This bug is not fixed after half year? What is that? Devs, what have you done, it's pretty useful trigger.

wanton oxide Sep 7, 2020, 11:53 PM

#

i'm sure they have enough food on their plates lol

#

its pretty easy to work around it too

prisma abyss Sep 7, 2020, 11:53 PM

#

I cannot believe it, i fix in different ways, and i made at end test world, and what did it see? It ignores always at first activate.

#

It confirmed exactly with old reported bug.

#

Udon should not bugged in such bad way.

wanton oxide Sep 7, 2020, 11:54 PM

#

well fcourse, thats because its not fixed yet

prisma abyss Sep 7, 2020, 11:54 PM

#

for half year!!!!

wanton oxide Sep 7, 2020, 11:54 PM

#

Udon isn't finished yet

prisma abyss Sep 7, 2020, 11:55 PM

#

I know it's not fixed.

#

But half year is long time.

wanton oxide Sep 7, 2020, 11:55 PM

#

yes

#

but there are more important issues to be fixed

#

eventually they'll probably fix it

prisma abyss Sep 7, 2020, 11:55 PM

#

kinda too long because i need it for udon graph

#

is it also bugged as Udon Sharp?

fiery yoke Sep 7, 2020, 11:56 PM

#

UdonSharp just converts C# code into UdonAssembly when applicable. It doesnt magically run the code.

prisma abyss Sep 7, 2020, 11:57 PM

#

You think it will also act same way ?

fiery yoke Sep 7, 2020, 11:57 PM

#

Also the reason why OnEnable is broken is because the program is loaded after Unity fires the OnEnable message for that UdonBehaviour

#

Udon is an incredibly complex thing software wise

serene moat Sep 7, 2020, 11:58 PM

#

UdonSharp runs on top of Udon, the OnEnable thing is a core issue in Udon so UdonSharp can't really do anything about it. I'd love to be able to fix that bug and others in Udon but I can't :(

fiery yoke Sep 7, 2020, 11:59 PM

#

I guess you could hide it behind the Start method and do some weird quirky workarounds there

#

but nothing I would recommend actually putting in U# xD

prisma abyss Sep 7, 2020, 11:59 PM

#

And we have event for spookality horror world, must run in sdk3 / udon but udon is part bugged, makes this less fun.... and we are forced to find workaround for it

#

Is OnDisable also bugged? Its reverse of OnEnable?

serene moat Sep 8, 2020, 12:00 AM

#

ah yeah I guess that'd be a workaround I could do

#

OnDisable works fine

prisma abyss Sep 8, 2020, 12:00 AM

#

that is weird

#

It's opposite, and it worked

fiery yoke Sep 8, 2020, 12:01 AM

#

@prisma abyss A temporary workaround is putting a SendCustomEvent node, connected to the Start event. Then send the event called "_onEnable"

prisma abyss Sep 8, 2020, 12:01 AM

#

Oke, i will work with OnDisable. It's just almost same for me

serene moat Sep 8, 2020, 12:01 AM

#

if I fix it like that though, things would get two OnEnabled calls when they fix it in a year xd so it's probably better that I don't

fiery yoke Sep 8, 2020, 12:02 AM

#

Well...then you would probably just fix it again :P

prisma abyss Sep 8, 2020, 12:02 AM

#

Send two times OnEnable is kinda crazy 🙂

fiery yoke Sep 8, 2020, 12:02 AM

#

I guess you could make it an option or something, just in case.

serene moat Sep 8, 2020, 12:02 AM

#

people's worlds would be broken at that point so they'd need to reupload

fiery yoke Sep 8, 2020, 12:02 AM

#

Ahh right

#

I mean

prisma abyss Sep 8, 2020, 12:03 AM

#

Well, i can do in OnDisable, you just do in reverse and it will work exact like OnEnable.

wanton oxide Sep 8, 2020, 12:03 AM

Is there list of known bugged functions online? I very like to see it

#

Ja nederlander lol

#

Because due bugs, i dont need spend hours to solve it, because it's already bugged. ooof.....

wanton oxide Sep 8, 2020, 12:04 AM

#

canny has most issues pretty well documented

fiery yoke Sep 8, 2020, 12:04 AM

#

There isnt a "list". Theres lots of cannys. I mostly know about bugs and problems from just being involved.

prisma abyss Sep 8, 2020, 12:04 AM

#

ach yeah

#

i want convert soon some games in udon, but with problems, i am not very sure now.... while SDK2 just works perfect. I can understand why big builders want do in SDK2 because it has less bugs compared to SDK3.

#

Thanks for explaining, but i am still angry and disappointed. I costs me 3 days to solve it. I got stronger feeling it must bugged but nobody said until now.

wanton oxide Sep 8, 2020, 12:10 AM

#

I don't think its necessarily much less stable or buggy

#

its just very different

#

and the parts that you are used to using in sdk2 happen to be the parts that are buggy now

#

and they don't get fixed because they usually wouldn't be used in sdk3 if you use it "properly" idk

prisma abyss Sep 8, 2020, 12:11 AM

#

PhaxeNor made some examples how to use it like SDK2, nice list, but kinda part useless because OnEnable will not work as expected.

wanton oxide Sep 8, 2020, 12:11 AM

#

the approach i take when working with udon is very different from sdk2, in udon i actually write code for everything

prisma abyss Sep 8, 2020, 12:11 AM

#

ah oke

wanton oxide Sep 8, 2020, 12:11 AM

#

and usually just test it all immediatly

#

when something doesn't work i can instantly try something else, and apply that everywhere

prisma abyss Sep 8, 2020, 12:11 AM

#

what is good way to debug code?

wanton oxide Sep 8, 2020, 12:12 AM

#

print statements

#

or rather, debug.log in unity i guess

prisma abyss Sep 8, 2020, 12:12 AM

#

udon has debug functions

#

and i should see it with debug window, right?

#

inside vrchat

wanton oxide Sep 8, 2020, 12:12 AM

#

if you enable that yes

#

but you can test most stuff inside the editor actually

#

or at least, unless its specifically related to players and interacting with them i can test stuff in the editor

prisma abyss Sep 8, 2020, 12:13 AM

#

yup, i know. Except OnEnable. I made testworld, saw it doesn't react immediately.

wanton oxide Sep 8, 2020, 12:14 AM

#

what are you trying to use onenable for?

prisma abyss Sep 8, 2020, 12:14 AM

#

door buttons enable

#

lucky i can also do it in animator

fiery yoke Sep 8, 2020, 12:14 AM

#

Btw in most cases you can use Start

wanton oxide Sep 8, 2020, 12:14 AM

#

yeah i was about to mention that

fiery yoke Sep 8, 2020, 12:14 AM

#

OnEnable is called whenever the Component or GameObject gets enabled

#

Start only happens once

wanton oxide Sep 8, 2020, 12:15 AM

#

either using start or using whatever function gets code going

#

so for example oninteract

prisma abyss Sep 8, 2020, 12:15 AM

#

I take OnStart will run when gameobject is active?

wanton oxide Sep 8, 2020, 12:15 AM

#

its not OnStart actually, just Start

prisma abyss Sep 8, 2020, 12:15 AM

#

oh

wanton oxide Sep 8, 2020, 12:16 AM

#

its ran whenever the gameobject is first enabled, or if its enabled from the start of the instance on the second frame (since thats when udon behaviours are loaded in iirc) so pretty much instantly

prisma abyss Sep 8, 2020, 12:19 AM

#

OnStart will run on enabled gameobject, and stop when gameobject is disabled. Is that correct?

wanton oxide Sep 8, 2020, 12:19 AM

#

No

fiery yoke Sep 8, 2020, 12:19 AM

#

Thats Update

#

Update runs every frame on an enabled GameObject

wanton oxide Sep 8, 2020, 12:19 AM

#

its called only once

#

yes

prisma abyss Sep 8, 2020, 12:19 AM

#

Update? Okee.

fiery yoke Sep 8, 2020, 12:19 AM

#

Start is only called once on the first frame the GameObject is enabled

prisma abyss Sep 8, 2020, 12:19 AM

#

I have also weird issue

#

The timer graph turned in error because single was used on bool.

#

but graph is fine, what the heck is single coming from?

#

The OnTimer example from PhaxeNor can result in error.

serene moat Sep 8, 2020, 12:21 AM

#

single is the name for a float

prisma abyss Sep 8, 2020, 12:21 AM

#

oke

#

in my way, it runs 1 time oke, but reuse it next time result in error.

#

This is even taken over from creator example. But it will give error when started again.

Then review your udon script

For each of these cases, approximately how often does VRC make world-breaking changes to Udon?

Existing worlds already uploaded break in-place and won't work until fixed and re-uploaded
Worlds break in Unity and can't be updated until fixes are added, but pre-existing uploaded versions still work

#

I know that it will just be guesses because alpha and everything. But I mean just from the recent experiences.

well close. that ui toggle work with only toggle. i just need come up a way to replace ui toggle with obj.

dull condor Sep 8, 2020, 6:20 PM

#

So I have a really basic animation (Just rotate the gameobject's transform by 90 deg) that refuses to play when there's an UdonBehavior attached to the object

#

The udonbehavior that's linked has no references to the animator or anything, but for some reason the animations fail to play any time the udonbehavior component is attached

#

I did notice that Apply Root Motion is being switched to "Handled by Script" even though I'm not doing anything with animations in that script

#

I'm stumped as to why it refuses to play

fiery yoke Sep 8, 2020, 6:24 PM

#

Root Motion is when the animation changes the position/rotation of the root object i.e. the object the Animator is on.
And UdonBehaviours will "pretend" that they are controlling that root motion. However by default they wont actually do anything. I've seen someone talk about how to enable it, but I cant remember. Maybe someone else knows, or you can google it.

dull condor Sep 8, 2020, 6:25 PM

#

I'm literally just trying to open a locker door

#

I wonder if I just need to make a parent object for each door, because the other doors in my world work

fiery yoke Sep 8, 2020, 6:25 PM

#

Well I mean one simple solution would be to not do root motion, but just have a child

#

Yeah

dull condor Sep 8, 2020, 6:25 PM

#

ugh that's annoying lol

#

ok I'll try it thanks

fiery yoke Sep 8, 2020, 6:25 PM

#

Sort of

#

But I think root motion has some other problems as well

#

Like its more computationally complex iirc

dull condor Sep 8, 2020, 6:26 PM

#

the problem is just a structural one because the locker has two doors that can be opened and closed independently

#

I wanted to make one script to control them both but I guess I'll have to put one script on each

fiery yoke Sep 8, 2020, 6:27 PM

#

You can just have an animator with two layers and two booleans

dull condor Sep 8, 2020, 6:27 PM

huh

I guess I could

lol now only one of them works

Random question at 3am while half asleep

#

Would it be possible to sync the scrolling of an UI menu using udon ? Didn't really look up network stuff atm

#

(implying only the master would be able to do anything with the said UI)

floral dove Sep 9, 2020, 12:58 AM

#

@lilac hatch - sure, you can write the local y position of the Rect Transform on your Scrolling area into a Synced Variable, then listen for changes on that variable and update each player's Scrolling area Rect Transform to match.

#

You could listen to OnValueChanged on the Scrollbar to know when to update the y position variable: https://docs.unity3d.com/2018.4/Documentation/Manual/script-Scrollbar.html

I'm trying to follow Vowgan's tutorial on creating working doors but he skims over a lot of details on how the Udon portion works and how to access the nodes he's using. I managed to figure out how to make the animator public but I just don't know where these nodes should be like Animator and Get Variable, they don't show up when I search in the create node menu.

#

Are there any other good channels for tutorials? I really need something step by step and all the in-depth VRChat scripting tutorials seem to be for sdk2.

valid oar Sep 9, 2020, 5:28 AM

#

With a bit of luck and experimentation, I managed to get an interactable button and a door that rapidly opens and closes so I'm getting there. I'm thinking the problem might be the animator but I think it's set up like it is in the tutorial and it's taken from an old sdk2 tutorial. It has an Idle default state with motion set to none, then a transition to the open state when the boolean parameter open is true which transitions to the close state when its false and then back to open when it's true again. Both the open and close animations seem to work properly when played in scene view.

Some things might be more obvious if you have more experience but feel free to DM me if you get stuck. I don't want to write out a big explanation if it's not necessary but he doesn't really tell you how to make the Udon script work, basically he just says to have an open and close animation and then goes to a doorknob that has an already made script and tells you to copy it without any further instruction. Maybe I'll make a tutorial for true beginners like myself that goes over it fully if I can manage to get my safety hazard fixed.
