Is it possible to turn off auto-compiling when working with the graph?

hardy fog Dec 15, 2020, 6:13 PM

#

Does Unity Networking have a list of players, or does Udon? It seems like such a fundamental thing that I shouldn't have to maintain my own list...

#

VRChat

OnNetworkReady

Triggered when OnNetworkReady is called by the local player.OnNetworkReady is called when the player has fully joined the room and received all buffered events from that room.

#

Oh, bruh. I didn't read all the events lol. oops

#

Hello,

#

what is the Udon best way of making players connected to a world instance communicate with an external server (e.g. receiving a counter from a website A or sending HTTP requests to that server or any alternative like WebSockets)?

#

Thanks

fiery yoke Dec 15, 2020, 7:06 PM

#

@west compass You cant. The only thing that can send a GET request is the video player and it should not be abused for that.

west compass Dec 15, 2020, 7:09 PM

thanks

hardy fog Dec 15, 2020, 8:09 PM

#

What does VRCPlayerAPI.GetPlayers even do? I know it sends a list of players to a target array, but where does that list come from?

lime void Dec 15, 2020, 8:21 PM

#

hey folks! quick question. I've been using udon for a map and I can't quite find a definitive working way on the latest SDK to make a seamless teleport- that is, a tele where when touched you automatically teleport instead of having to manually click/interact with it

#

I have UdonSharp as well and made a script via a youtube tut I followed, but that one isn't quite working. I'm happy to focus on diagnosing why that one is bugged out and makes me teleport to weird locations/heights, but I'm assuming there's a much easier simple way to make a seamless teleport graph or script from scratch instead?

to make something like that instead of a Interact event do a OnPlayerTriggerEnter event. i can send a screenshot of my version that works pretty well.

lime void hey folks! quick question. I've been using udon for a map and I can't quite find...

This is what i have. The upper part that grabs the name and sets the text is not needed and was just for testing. You would assign a object to the player destination the the way that is facing and where it is what the player will be set to. it might have to test it a few times to make sure the object is in the right direction.

Does an object with multiple colliders/triggers receive events from all of them?

#

And also, is there any way to make an object bounce off avatars?

vital quail Dec 16, 2020, 12:36 AM

So I just started messing with udon and whenever I test my world I get stuck at the spawn point and can't move anywhere

slim hound Dec 16, 2020, 12:40 AM

#

If you don't think its that you could check window > analysis > physics debugger also

vital quail Dec 16, 2020, 12:42 AM

ancient spindle Dec 16, 2020, 3:25 AM

#

is there a way to make a "remote" of some sort in the udon graph? basically what i have in mind, is a player has an object they can pick up. and the button that lets them "use" it, i want to make that toggle something in my world (and sync to everyone in the instance if possible)

slim hound Dec 16, 2020, 3:27 AM

#

Pickup object and then in the graph you can create a OnPickupUseDown event and do something from there

ancient spindle Dec 16, 2020, 3:29 AM

#

is there a difference between OnPickupUseDown and OnPickupUseUp?

#

xD and how would you "use" an object in desktop mode. lol

slim hound Dec 16, 2020, 3:37 AM

#

Down will trigger when you press and Up will trigger when you release the button press

#

if the pickup is set as autohold it will fire when you press your mouse 1 button

Has anyone had this issue with SDK3? I'm on the current latest version.
Setup a project earlier, installed some assets from the store and noticed it took a really long time to Play the scene.
After some investigation, according to the editor logs, every time Play is hit, something is performing a rehash of every unity scene and prefab in my project, even on an empty scene. After much testing, I discovered it happens on a brand new project after installing Udon SDK3.
Does anyone know if this is something from the latest sdk or has this always been the case? And if so, if there is a way to disable this behavior? Seems unintended and potentially a bug.

#

Only seems to be an issue if you have a lot of scenes and prefabs in your project, but still.

#

Fwiw, this does not happen on sdk2

viscid reef Dec 16, 2020, 8:57 AM

#

nevermind, looks like its just doing it for prefabs with udon behaviors on them

viscid reef Dec 16, 2020, 9:25 AM

#

Stilll, it looks like time for the editor to play a scene goes up significantly the more assets are in a project. With just the udon sdk3, it was taking me 4-6 seconds after hitting play to load into an empty scene. After importing a few model asset packages, it takes 20 seconds to play the same empty scene. This isnt the case for sdk2 projects.

fiery yoke Dec 16, 2020, 1:53 PM

#

@viscid reef For "security reasons" the SDK has to scan every prefab in your assets I think. However I think that should only happen when building the scene. Not sure tho.

So I've been stumped on an issues revolving around what I believe to be object collisions. I have a projectile object that for some reason throws an excemption that never describes where it takes place, but always happens. This exception is isolated to VRChat as it works in Unity testing and with CyanEmu.

Regardless if disabling synced objects, removing all [UdonSynced] variables in the behavior, this issue persists.

bleak widget Dec 16, 2020, 5:26 PM

#

Is there any way to check if an interact button is being held down without the user having to pick up the object?

unborn hornet Dec 16, 2020, 5:29 PM

#

For just the Interact event, probably not. You could do something like a "Is player's finger inside a trigger" kind of check using the OnPlayerCollisionStay event, but that'd really only work for VR.

#

Another alternative is to have a larger trigger zone directly around the interact object, and have the interact "start" the check, then use OnPlayerTriggerStay to check if the player is still near it.

#

Would need more details on your usecase otherwise.

bleak widget Dec 16, 2020, 5:44 PM

#

Hmm.. yeah I dont think those would work well for my use case. I was thinking about how I would make a button that a desktop or vr user could click and hold but the only way I could think to do that was if I detected picking up instead. I suppose i could still do that but it isnt super intuitive in vr

unborn hornet Dec 16, 2020, 6:19 PM

#

🤔 you might be able to fudge it with an invisible pickup (an object without a mesh), that when OnPickupUseUp is called, it gets dropped and moved back into the original position.

bleak widget Dec 16, 2020, 6:45 PM

#

That works great for desktop. Ive used that method for other things. However, in vr, the controls for buttons are on triggers while pickups are on grips. So that leads some non intuitive buttons for a lot of vr users

and also

#

how can u make it to where u jump

errant pilot Dec 17, 2020, 2:21 AM

#

@unreal bobcat So here is a nice rundown on colliders.
All colliders will prevent things from passing through. You can set it to collide with certain objects, but by default it will collide with all

The basic colliders, box, capsule, sphere, ect. will be a basic shape and are the best for performance compared to mesh colliders. If you want the collider to be used as a trigger, select 'is trigger' and it will also allow players to walk through it.

The mesh collider is a complex collider that uses the object's mesh for each point of the collider. It can be costly in some cases so be careful to use it.

Hey I just got into the udon graph a few weeks ago and I was wondering if there is a way to instantiate an object globally for everyone that is synced properly.
I seem to get it to work sometimes, but they don't seem to appear at the same position. I added a vrc pickup to the prefab and a vrc behaviour with sync object on, but that doesn't seem to be the solution

scarlet lake Dec 17, 2020, 12:15 PM

#

Everyone with questions that were unanswered last night dm me and I'll help out

#

@thorn coral and for you syncing is a bit of a curve, you can use sendcustomnetworkevent to send a command globally

thorn coral Dec 17, 2020, 12:19 PM

#

@scarlet lake thanks I'll try that. May I dm you later if that doesn't work or I can't figure it out?

scarlet lake Dec 17, 2020, 12:23 PM

#

For sure and for new people who enter wont get synced right away so for every event that changes things, you gotta update it for the player who interacted with it and THEN use deserialzation and synced bool variables to keep track of everything

#

It took me a while studying the example scene till I understood how deserilization works

#

@thorn coral

#

It's kinda crazy how unfriendly udon is to new people

thorn coral Dec 17, 2020, 12:32 PM

Before I go to far into this rabbithole, can you syncronize position instantiated objects?

You cannot syncronise instantiated objects

chilly crater Dec 17, 2020, 6:49 PM

ooof

floral dove Dec 17, 2020, 6:54 PM

@chilly crater - you can create the objects you want to use ahead of time and turn them on and off to create the appearance of instantiation, these can be synchronized.

chilly crater Dec 17, 2020, 6:54 PM

Synchronized positions doesn't work on instantiated objects even if they have an udon behavior on them in the prefab? What if you just wrote your own sync position behavior? Or would that not be possible?

scarlet lake Dec 17, 2020, 8:13 PM

#

@bleak widget it is possible in two ways, sync position only effects objects you grab, to make like toggles global you gotta use a custom event

#

then you gotta call that custom event in a node called sendcustomnetworkevent and set it to global

#

the best way is with deserialization though cause then you can sync to new players as well

udon networking is kinda terrible at first

Ultimate Beginners Guide To Udon

What is udon? Udon is a new way to set up events and actions in your world using graphs and nodes to have a better visualization of your scripts, such as a mirror you toggle on and off. I’ll be using this as the main example throughout this thread. Nodes are like events and actions you can connect to each other with “noodles”. Most of them are...

#

i even went as far as to be able to sync animations kinda

#

the only issue with udon and syncing is if new people come into your instance, they wont see the current part of a looping animation

but like simple door animations can be perfectly synced

You can't sync instantiated objects IIRC. Make an object pool instead

scarlet lake Dec 17, 2020, 8:25 PM

#

what do you mean by instantiated? @wheat rover

wheat rover Dec 17, 2020, 8:26 PM

#

Objects created with VRCInstantiate

scarlet lake Dec 17, 2020, 8:26 PM

#

ohhh

#

i feel like that should be easily synced

bleak widget Dec 17, 2020, 8:29 PM

#

I mean if udon behaviors on an instantiated object run, then I think it would be possible to write a behavior that would sync the positions together if the built in sync system didn't work on them

chilly crater Dec 17, 2020, 8:54 PM

#

Now I'm figuring out how to stop a particle system on interact up and start it on interact down.

wheat rover Dec 17, 2020, 8:56 PM

#

It's a VRChat problem. There's no practical way to do that at all, since VRC won't even sync the presence of an instantiated object properly.
Again, just use an object pool.

hardy fog Dec 17, 2020, 9:00 PM

chilly crater I made snowball guns.

Can you just have like 40 snowballs for each gun hidden outside the environment, then move them in when you need them, and move the last snowballs fired back the the hidden place? This is just an efficient way to do ammo/bullets, but it would also solve your problem.

Could always just predefine the objects in an array and then use that to reset the positions back to their original position. For that example you could on start define the objects location into a vector3 then have a respawn method that teleports them back.

How am I supposed to create and open a new Udon graph?

I was able to adjust gravity on the default Udon world graph because the open in graph button is there:

But I want to respawn players when they hit a collider, yet I cannot seem to figure out how to open the new graph I created:

Yikes bud

jaunty schooner Dec 18, 2020, 11:12 AM

#

As you can see there's no open button, clicking on the script itself shows nothing useful, and clicking open empty opens the empty graph I have to put on every pickup, so I don't want to edit that.

#

📎 unknown.png

#

Right clicking on the script also shows no useful options to open the graph.

scarlet lake Dec 18, 2020, 11:13 AM

#

You're inspecting the script itself

#

So go to a gameobject maybe one you wanna make a button idk, then create a component called udonbehavior

#

There you can open an already compiled graph or a new one

jaunty schooner Dec 18, 2020, 11:14 AM

#

Look at my first screenshot again. I did that.

#

Err, second screenshot.

#

There are also no errors in my console, and I restated Unity.

scarlet lake Dec 18, 2020, 11:16 AM

#

Something way wrong here

#

Try creating a udonbehavior component on a different object and send me a screenshot of that

#

@jaunty schooner

It's weird that the compiled file is in that directory

native estuary Dec 18, 2020, 11:18 AM

New object, added Udon component, create new udon clicked. That's what I get.

#

Wait, there's a dropdown box... IT's on assembly by default...

native estuary Dec 18, 2020, 11:20 AM

But what did you have selected in the dropdown before clicking create?

#

Graph should be the default

jaunty schooner Dec 18, 2020, 11:20 AM

Why would the dropdown default to something that doesn't let me edit it?

native estuary Dec 18, 2020, 11:20 AM

You most likely changed it by accident at one point so it stayed there

You can edit assembly though if you know assembly

jaunty schooner Dec 18, 2020, 11:21 AM

A new component should default to whatever the default is, shouldn't it? Not to what I may have selected the last time I created or edited a component on an object...

I'm getting the button now though, so thanks for that...

Well usually people want to keep making the same type of udon behaviours be it either udon sharp, assembly or graph

jaunty schooner Dec 18, 2020, 11:23 AM

#

Well in that case I might keep the button but throw an informative error that you can't open an assembly in the graph to hint at what the solution is.

native estuary Dec 18, 2020, 11:23 AM

#

For assembly you have the text box there that is also part of udon where you can write udon code

#

So it's not really an error

jaunty schooner Dec 18, 2020, 11:24 AM

#

I didn't mean it's an error, I mean the user's error. I had no way of knowing that the reason I couldn't open the graph was because I was working with the wrong kind of file.

Well I'm already lost. I want to teleport players back to spawn when they collide with a trigger volume. But none of this makes sense. Is "instance" the player or object I want to teleport? Is there a LocalPlayer object somewhere which I have to feed into that? How do I tell OnEnterCollision I want to know when the player collided and not something else? What the heck is "collision other"?

📎 unknown.png

#

The teleport is also under VRCPlayerApi which ought to deal with Players not general objects since Player is in the name so perhaps that is a function specific for telporting players?

Well I guess I screwed up already because it appears there's functions specifically for detecting player collisions... https://docs.vrchat.com/docs/player-collisions

Player Collisions

Udon has three ways to detect when a Player and an Object Collide - Triggers, Physics, and Particles.

Ultimate Beginners Guide To Udon

What is udon? Udon is a new way to set up events and actions in your world using graphs and nodes to have a better visualization of your scripts, such as a mirror you toggle on and off. I’ll be using this as the main example throughout this thread. Nodes are like events and actions you can connect to each other with “noodles”. Most of them are...

jaunty schooner Dec 18, 2020, 11:43 AM

#

Oh wait it was searching something other than all nodes cause I had a node selected? Ugh.

scarlet lake Dec 18, 2020, 11:43 AM

#

Yeah it does that haha

#

Instance would be the player and you can get local playerapi

#

I should probably include on my tutorial that to set synced variables, you gotta search on noodle drop

jaunty schooner Dec 18, 2020, 11:45 AM

#

Cool, so I can just drag my transform into the window and it makes a node...

📎 unknown.png

scarlet lake Dec 18, 2020, 11:45 AM

#

Oh my god

jaunty schooner Dec 18, 2020, 11:46 AM

#

Aggghh it won't let me connect that output to the inputs there... Cause it's a whole transform... Can I drag pieces? 😄

#

Nope can't just drag position into there.

scarlet lake Dec 18, 2020, 11:46 AM

#

Okay so for the place you want to send a person, create an empty game object at that location and use it to set up the cordinates

#

Idk why you're trying to use the world prefab for literally anything other than adjusting jump height and walk speed

jaunty schooner Dec 18, 2020, 11:47 AM

#

That's what VRCWorld is. Its used as the spawn point.

scarlet lake Dec 18, 2020, 11:47 AM

#

I think I grew a tumor

jaunty schooner Dec 18, 2020, 11:47 AM

#

Because that's what VRC says to do in their tutorials?

#

If you just want one spawn point theres no need to make an extra game object.

native estuary Dec 18, 2020, 11:47 AM

#

You should be able to get "position" from the transform and drag that into the teleport

jaunty schooner Dec 18, 2020, 11:48 AM

#

But how...

scarlet lake Dec 18, 2020, 11:48 AM

#

I suppose you could

#

I got that answer

#

Transform get position

#

From your world variable

native estuary Dec 18, 2020, 11:49 AM

#

^^

scarlet lake Dec 18, 2020, 11:49 AM

#

And transform get rotation etc etc

#

It is kinda awkward searching for what you need since things are in like categories

#

I always have a hard time remembering if a node is under networking or playerapi and getting types can trip me up too

native estuary Dec 18, 2020, 11:51 AM

#

Enabling search on drop from the settings on the top right helped me find correct nodes pretty fast

scarlet lake Dec 18, 2020, 11:51 AM

#

I find it to be more of a hassle

jaunty schooner Dec 18, 2020, 11:51 AM

#

I understand the concept of extracting position and rotation from a transform, but I can't find the node I need to do that.

📎 unknown.png

scarlet lake Dec 18, 2020, 11:52 AM

#

So when you search you're first searching for what categories your nodes are under

#

So since we are looking for transforms, we first type in transform, click it and it gives us a bunch of transform options

jaunty schooner Dec 18, 2020, 11:53 AM

#

Oh wait I can drag out a noodle and get a list of things it can connect to...

scarlet lake Dec 18, 2020, 11:53 AM

I just need to keep playing with it to learn what does what because the docs are missing 99% of the information, but I was able to guess that the UnityTransform thing was the node I needed.

"So the vrcworld prefab is the physical object in your scene that you get the cordinates in the skybox graph right" - Yes?
"So how does the graph know which object is the vrcworld prefab" - I dragged its transform into the graph?
"So on the sky object's udonbehavior there should be a list of public variables, you put the asset there" - I don't understand what you're getting at. The variable is set public in the graph. And if I click on the object in the heirarchy there is nothing there about making variables public.

#

"So you're looking at the components of the vrcworld prefab in the last screenshot right" - Yes.

scarlet lake Dec 18, 2020, 12:31 PM

Just cause you named it vrcworld doesnt mean its pulling info from the prefab

Okay good on the right, see how it says no public variables

jaunty schooner Dec 18, 2020, 12:32 PM

#

"Okay, how does the transform variable know which object from your hierarchy its getting the transform info from"

I dragged the transform from the VRCWorld Prefab into the Udon window. So presumably that is a reference to that object, seeing as that's how I would have coded it and it took on the name of the object I dragged it from, and there is no input to it for an object reference so there's no place for me to drag the original object anyway.

#

Yes, I see how it says "no public variables" but do you see how it says on the left "public" is checked? So I don't know why it's not listed on the right.

#

"Just cause you named it vrcworld doesnt mean its pulling info from the prefab"

I didn't name it that. I dragged the VRCWorld transform into the Udon window. IT chose that name for it.

scarlet lake Dec 18, 2020, 12:35 PM

Theres something wrong there cause you marked it public but the component says theres no public variables

But anyway I see now what you were trying to tell me about setting the public variable and why you thought I hadn't specified it. You thought I just made a variable and never initialized it by filling out that field in the inspector. And I couldn't see the field there so I thought you wanted me to drag the object into the Variables node in the Udon window.

scarlet lake Dec 18, 2020, 12:49 PM

Unity is hella weird sometimes, it'll crash all together in the middle of uploading if you dont turn off future proofing

slim hound Dec 18, 2020, 12:50 PM

So dragging and dropping to set variables works only if you have opened the graph with the Open Udon Graph button on the udon behavior, if you tab away and tab back to the udon graph it will break your udon graph editor when trying to drag drop variables

I know what's wrong here

#

No box collider

jaunty schooner Dec 18, 2020, 4:47 PM

#

unreal bobcat

You say it doesn't show in game, so I don't know if you mean you can't see yourself pick up the object or that other people can't see you pick it up, but if other people can't see you pick it up that's because you need to add an Udon script to the object, and check sync position. Search for Empty in the assets folder, there is a special empty script to attach to things like pickups where you don't need them to do anything else.

#

@scarlet lake He has a mesh collider. You don't need a box collider for a pickup. My cars can be picked up and thrown:

📎 unknown.png

#

I don't know for certain that non-convex colliders can be pickups though. I think they can be. But you could try checking convex.

scarlet lake Dec 18, 2020, 4:49 PM

#

I must be having some weird issues then cause mesh never works for me

#

What's the difference between the two?

jaunty schooner Dec 18, 2020, 4:51 PM

#

A non-convex collider is like an L shape. It's concave. If you check convex, Unity will buiild a collider mesh which is convex. In the case of an L shape, it would become a triangle.

#

The difference is also that Unity can't use concave colliders as triggers. I suspect the pickup script might expect convex for that reason.

#

But you don't need to tick the isTrigger on the collider yourself. I just am guessing the pickup script does something like that maybe.

#

And you shoudn't tick it or your object won't collide with the world.

scarlet lake Dec 18, 2020, 4:54 PM

#

@jaunty schooner maybe that guy with the pickup issue needs to tick the convex option on his mesh collider

jaunty schooner Dec 18, 2020, 4:55 PM

#

So this taxi, with convex not ticked, has a collider shaped like the taxi...

📎 unknown.png

scarlet lake Dec 18, 2020, 4:55 PM

#

I was told a while back that mesh colliders aren't really to be used

jaunty schooner Dec 18, 2020, 4:55 PM

#

But with it ticked, it builds a convex mesh around it internally for simplified collision checks:

📎 unknown.png

#

Mesh colliders work just fine. That world is mine and has like a hundred cars you can pick up and throw. And you can pile them all up and it won't crash. And the reason it won't crash is cause I unticked "change ownership on collision". That wasn't needed and apparently all the cars colliding with each other at once changing ownership eventually kills the networking code.

scarlet lake Dec 18, 2020, 4:58 PM

#

Lmao yeah Idk what that's for really cause it never seems to effect my object behavior

jaunty schooner Dec 18, 2020, 4:58 PM

#

And the framerate in my world is decent too. It's called Big City. Check it out. Unity almost certainly uses it's own internal box colliders when doing the physics calculations and only switches to the mesh when the boxes intersect.

scarlet lake Dec 18, 2020, 4:59 PM

#

I've been working on optimizing myself, I've come along way since my first world of real time lighting

jaunty schooner Dec 18, 2020, 4:59 PM

#

Well ownership I believe is like... if I pick up an axe, it sets a variable saying I am the owner of that axe. The last one to touch it. Now, what can you do with that info? Well, I think stuff like the combat system could have used it to say, tell whose grenade blew you up. Murder probably uses it to determine who stabbed who too.

scarlet lake Dec 18, 2020, 5:00 PM

#

That makes sense, but would it have any effect on an interact button

jaunty schooner Dec 18, 2020, 5:01 PM

Probably not. But in most cases it also probably doesn't matter since it would only be one network event. Whereas I had a hundred cars all bouncing around and transmitting hundreds of events.

scarlet lake Dec 18, 2020, 5:02 PM

I do have a particular issue, oncollisionentertrigger

I had it set to toggle a mirror and it worked fine for enter and exit but if someone else came inside the collider it would turn off my mirrors even though those are supposed to be local

Is there an easier way to do a timer in udongraph than this? https://i.imgur.com/ZgXBWLq.png

Imgur

bleak widget Dec 18, 2020, 7:25 PM

#

Yes. You can use time.time or time.realtimesincestartup along with some "endtime" variable and just check to see if the time has exceeded the end time. Then just reset end time up by a certain amount based on the current time. Idk if that made sense

chilly crater Dec 18, 2020, 7:26 PM

#

I just want to disable something five seconds after going active.

#

Oh wait, I can throw my script onto the object. Then it will do it automagically

#

No need for a timer script for each projectile...

bleak widget Dec 18, 2020, 7:27 PM

#

Yup

chilly crater Dec 18, 2020, 7:32 PM

#

I should probably swap that timercount and the set active.

#

If it turns off, the timercount won't be set.

#

something something script stops when gameobject is inactive

I pooled the objects, but they still aren't showing up anywhere but local. Do I have to add other stuff to it?

Each snowgun has six snowballs (that aren't prefabs) for ammo. each snowball is synced. But they won't render on other clients.

#

Should I be giving each gun script a network fire event?

bleak widget Dec 18, 2020, 9:44 PM

#

The issue might not be that the snowballs position isn't being synced but that they are not being shown on all instances. Make sure that whatever code you have to show the snowballs, runs across all instances

chilly crater Dec 18, 2020, 9:45 PM

How would I do that?

send event for the activation?

Oh, is that the variables?

Hi I have absolutely no knowledge of Udon or scripting beyond basics. How hard is it to learn to be a noodlemancer?

fiery yoke Dec 18, 2020, 11:25 PM

#

@astral moon It depends on how easy it is for you to understand and learn about general programming concepts, like Objects, Fields, Flow, Loops etc. etc.
Udon is built on top of Unitys C# and ofcourse VRChat specific stuff. Its easy to get into but hard to master. Especially when it comes to networking stuff. Basic stuff is simple enough for every beginner I would say.

Hey everyone, I was thinking about making a world, and I had questions about publishing/uploading worlds to the website; Is there a way I can make a world that has a "Friends" instance only? One where someone cannot create other instances, but myself and any of my friends can join without me having to invite them?

fiery yoke Dec 19, 2020, 4:50 AM

#

If you dont publish your world it will pretty much work like that. Just upload it without publishing it to the labs

compact stirrup Dec 19, 2020, 4:51 AM

#

so even if someone random person got the link to it, they'd not be able to join without being on my friends list? or would I have to make sure that wasn't shared?

#

An account whitelisting feature for worlds would be great, wouldn't even need to worry about this stuff, hahah

waxen breach Dec 19, 2020, 5:02 AM

#

compact stirrup An account whitelisting feature for worlds would be great, wouldn't even need to...

You could make a world that is public and add a door that only opens to people you add to it. I have a udon graph that i was going to make fully public soon that will check a players name and if it matches the name you put down it will execute the next stuff. if it doesn't it will do nothing (unless you add something to the false part). Ill send how i did it in about 30 min to an hour

compact stirrup Dec 19, 2020, 5:04 AM

#

Thanks, that's an idea!

waxen breach Dec 19, 2020, 5:07 AM

I use the name check in a world that has a DJ in it. To prevent abuse there is a barrier around the DJ stuff and only me and 2 other people can get inside and use the controls.

compact stirrup Dec 19, 2020, 5:09 AM

That is a nice thing to have, but I'd like to be able to prevent random people from connecting to the world at all, if I could

waxen breach Dec 19, 2020, 5:10 AM

I honestly dont know a way to prevent that. Not making a world public would work but i remember it being weird when trying to join someone else for a preview of a world before it became public

wheat rover Simply, any synced byte or short variables I'm using cause errors. Ints and floa...

Welcome to Udon Alpha. Fixes coming soon™

wheat rover Dec 19, 2020, 6:11 AM

#

I feel like the more I use Udon the more I understand why no one does anything very cool with it.

#

Also, as I feared, player.playerId is different between clients...making object ownership the only real way to track players between clients.

#

It works but like jesus christ
I don't mean to dunk on VRC or anything but their development tools are honestly some of the absolute worst I've seen in a game with user generated content
There's so much basic stuff that should be there but just isn't

#

It's honestly going to kill the game once someone with a better platform comes along. Alas, servers are expensive and they have the upper hand there, but that can't last them forever...
Feh, wrong place for such a rant anyways.

#

...But also, object ownership is reset on leave before OnPlayerLeft. Which means there's no good, non-hacky way to actually tell who left, in a theoretical game, to clean up their stuff.
I'm losing my mind here.

tall vault Dec 19, 2020, 6:43 AM

#

Does it at least fire OnOwnershipTransferred when ownership gets reset? If so you should be able to keep a note of the playerid that used to own the object and do cleanup when OnPlayerLeft gets called

wheat rover Dec 19, 2020, 6:45 AM

#

I wound up just giving up and tracking players for network purposes using ownership, while also locally tracking their playerId and using that to determine who left.
It's a bit hacky and I anticipate it to, at some point, break in extreme circumstances, but that's what you gotta deal with in VRChat I guess.

Player Collisions

Udon has three ways to detect when a Player and an Object Collide - Triggers, Physics, and Particles. Triggers If you want to detect when a player has entered or exited an area, your best bet will be to use the OnPlayerTrigger events. There are three of these: OnPlayerTriggerEnter is called when a ...

#

#

Nevermind, I found it. For some reason they have example scenes both under Examples/Samples Assets/Scenes and in the root Examples folder.

📎 unknown.png

#

Ah, I see where I went wrong. There's both an OnPlayerTriggerEnter and OnPlayerCollisionEnter. I got confused because OnPlayerCollision talks about a player entering a collider... Which I'd think should only be possible if the collider is set to trigger. Otherwise one would assume the colliders will never intersect, only touch. So I'm not exactly sure how that works. It suggests its used for bullets, because they have to interact with the environment... But unless they're passing right through players, I don't understand what the whole enter and exit thing is about with them. Do they pass through players? And if not, are OnCollisionEnter and Exit both called when the bullet bounces off you?

chilly crater Dec 19, 2020, 5:44 PM

If I want an object synced with collision transfer (and it already has a script) do I have to add a new udon behavior?

It can easily break Networking and other VRC Internal behaviour

And I dont really see the pros of it

serene moat Dec 19, 2020, 9:06 PM

I mean if there weren't pros, Unity wouldn't use components in the first place

fiery yoke Dec 19, 2020, 9:07 PM

Well I mean you can always have a child that has the other behaviour

#

Ofcourse in normal Unity thats unnessecary

#

But Udon is not normal Unity

#

:P

serene moat Dec 19, 2020, 9:07 PM

I mean you could do that in Unity too if they didn't have components

#

Especially since in Unity components are seperate

#

In Udon its just all UdonBehaviour

serene moat Dec 19, 2020, 9:08 PM

#

Udon program assets are the separation in Udon due to how it needs to function because of how Unity works

Yeah but as I said it might cause issues when "finding" the UdonBehaviour

chilly crater Dec 19, 2020, 9:09 PM

"Well I mean you can always have a child that has the other behaviour" I'm sorry for the off topic, but I find this hilarious out of context.

fiery yoke Dec 19, 2020, 9:09 PM

#

if the dispatcher is written in a way were it just sends a networked event to a GameObject and then expects it to be the first UdonBehaviour on it

#

then it would break if you have more than one and the first one is not used for Networking

chilly crater Dec 19, 2020, 9:10 PM

#

TIL that synced variables are bad. It messes with position sync.

fiery yoke Dec 19, 2020, 9:10 PM

#

More the other way round

#

Position Sync is lazy. Meaning that if the object doesnt move (i.e. the rigidbody is sleeping) the sync completely stops

#

Which also effects the synced variables

But anyways, regardless of the network events...

#

from within the graph, I would like to be able to just do something like thisScript -> SendCustomEvent 'EventThing' instead of having to search for the current script from the game object.

It could reduce the number of externs, as well as make it easier to deal with multiple graphs per object.

fiery yoke Dec 19, 2020, 9:14 PM

Yeah in UdonSharp you can do that easily by actually using this. The graph apperantly doesnt let you do that.

an a component is also an object

Which UdonBehaviours can only be sure that there exists exactly 3 things: Itself (UdonBehaviour instance) a GameObject it exists on and a Transform the GameObject must have. So it will default to those if not provided. Otherwise it will be null.

fiery yoke Which UdonBehaviours can only be sure that there exists exactly 3 things: Itself...

Which is accurate from a technical standpoint, but can be confusing for those not deep in the weeds of how udon works.

fiery yoke Dec 19, 2020, 9:34 PM

unborn hornet Dec 19, 2020, 9:37 PM

In mathematics, a unary operation is an operation with only one operand, i.e. a single input.
Unary = single input
Negation = opposite
When the single input is a bool, it toggles between the two possible values.

When your variable itself Is named boolean or int

fiery yoke Dec 19, 2020, 9:43 PM

#

the only reserved term is bool. Boolean is not reserved, therefor valid :P
But yeah I just mean that the steps necessary to express an idea in the graph is exponentially higher

chilly crater Dec 19, 2020, 9:43 PM

#

this is where naming conventions come into play.

scarlet lake Dec 19, 2020, 9:43 PM

#

I once wrote a huge program naming all my variables like a1 a2 b1 b2

fiery yoke Dec 19, 2020, 9:44 PM

#

Theres a reason its called a programming-language

#

Because you express concepts and ideas by a formal logic with the auxiliary help of natural language.

Using a graph also does that, but it basically just puts the words into boxes.

scarlet lake Dec 19, 2020, 9:45 PM

It is a nice visually and super easy to read I give it that

fiery yoke Dec 19, 2020, 9:45 PM

#

I dont think its nicer than scripted code tho. Maybe thats biased

scarlet lake Dec 19, 2020, 9:45 PM

#

How would I get started with u#? Is it like the same syntax as like c#?

fiery yoke Dec 19, 2020, 9:46 PM

#

U# is basically a subset of C#. Some things work exactly how you expect it, some dont.

chilly crater Dec 19, 2020, 9:46 PM

#

One of my friends compared the graph to a rough draft. Yeah, it works, but you can refine it further.

The thing that keeps messing with my mind is vowgans roomba prefab like it's crazy and I still dont understand how it syncs when its moving, and i spent like a week on networking

quartz meadow Dec 19, 2020, 10:39 PM

#

Alright, I am trying to import a huge jagged array into u# for a project, the cs file that holds it is nearly 1 mb. When udon sharp attempts to compile it, it hangs for multiple hours. I am going to try updating u# and the sdk3 to the latest, but does anyone else have any other suggestions on what to do?

#

im thinking of maybe splitting it up into several files, since its a jagged array

#

would be a PITA to work with though, lol

scarlet lake Dec 19, 2020, 10:46 PM

#

That sounds like a massive array

quartz meadow Dec 19, 2020, 10:46 PM

#

it is absolutely absurd I know, its for a neural network so I can't really cut it down

#

I am well aware I am pushing udon way past what its meant to do here

#

but I think this is a u# compiler issue

serene moat Dec 19, 2020, 10:48 PM

#

you're probably better off using the editor scripting api to make a editor script that just sets up the jagged array. U# doesn't handle your jagged arrays directly when you init them in a field initializer, it goes straight to Roslyn for the most part. You're just likely breaking a production compiler by abusing it like that. If you're doing something like initializing an array that large in Start, Udon would probably hang long enough to time out and crash the behaviour.

#

#

Also while you may be able to put the data in, you're going to run into fundamental performance issues if you want to do a neural network in Udon. You start seeing frame time take a visible hit from just iterating 40 times in update and doing nothing else

quartz meadow Dec 19, 2020, 10:50 PM

#

I have a few ideas about that, thankfully this does not need to run in real time / per frame

#

and its all local, no networking to deal with here

serene moat Dec 19, 2020, 10:51 PM

#

Yeah you can do time slicing there, but you could also just run it all in shader at that point and run it all in realtime

quartz meadow Dec 19, 2020, 10:51 PM

#

yeah, that will be the next step. I just want to get a proof of concept first

#

im assuming Shaders are capable to taking in - sending out variables? I think I have seen it done before

serene moat Dec 19, 2020, 10:52 PM

#

you can set variables on shaders from the CPU, you cannot trivially send data back from the GPU to the CPU, but you can make it work at a performance overhead via ReadPixels

normal yarrow Dec 20, 2020, 1:17 AM

Oh dang.

#

Yeah I had them hosted elsewhere.

#

I would've had the videos played locally but the VRC Unity Player doesn't want that.

unborn hornet Dec 20, 2020, 3:42 AM

#

You could rig something up as an extension of my TV prefab. Hide the visual elements provided and attach your own screens and speakers to the player provided. It handles the sync and rate-limiting pretty well in my tests. It'd be cool to see if it is reliable enough for a usecase like yours...

Hey everyone, I have a question for udon/vrchat in general. Is it possible for me to have a script that instantiates an object for only a single client on a server. For example, could I make a platform that only one person could stand on, but others couldn't collide with?

#

in lieu of making the gameobject on the client, would be possible to instantiate a clone of a gameobject that other players could ignore the collision of, something that would only collide with one person?

mossy anvil Dec 20, 2020, 8:28 AM

#

if it's not udon send custom networked it should be local by default

compact stirrup Dec 20, 2020, 8:31 AM

#

Hm, what I'd like to do is have a platform that players can stand on, and if they push a button, the person pushing the button is lifted up to the floor they push, but everyone else on the platform is unaffected. The collider would be invisible, so it's like they're floating up to the floor

#

currently, if too may people use it at the same time, it spawns too many colliders and people get yeeted off the platform

dapper lion Dec 20, 2020, 8:33 AM

I know this is a shot in the dark, and probably not possible but I figured I would throw it out there.....Theoretically, would it be possible to over-ride spatial audio for a single avatar in a world, and have their audio become 'world audio', and have that audio in stereo? (this is for a performance world I'm trying to develop) for example, have a toggle to turn it on for that avatar, and when they preform their sound comes out in two channel stereo (world music) rather than from the spot they are standing in.

These are all the things you can do to Player / Avatar Audio with Udon: https://docs.vrchat.com/docs/player-audio
I don't see a way to make what you are describing with those properties. You can disable the lowpass filter for a more full range using Player Audio.
A different approach would be to have your user do a livestream with stereo audio, then have a Video Player in the world with 2D audio play it in realtime. There would be some delay, but with AVPro Low Latency and a fast re-stream it should be usable.

tribal meadow Dec 20, 2020, 10:31 PM

OK thanks, I was thinking of that too, I was just curious if what I wanted to do was even possible, sounds like it's not at this point, I'll take a look at those docs though!

If you're trying to make something interactive (a dial you can turn, etc), there's an easier way to do it. Make a pickup object that's just the collider, and tie it to your actual interactable thing with a rotation constraint that has just the axis you want locked. Then set its position to reset to the object's on PickupDrop.
