@fiery yoke well, I'm on Quest+Link so I just have to pop out the USB cable. I usually leave it out while I'm doing most of my development and just plug it in for a final check after I've tested everything on desktop.
#udon-general
floral dove
fiery yoke
Plugging the USB in and out, probably isnt good for the connector in the long run tho. Its still nice to have that option, wish it would just come with the SDK 🙃
floral dove
It's a good feature request - a checkbox to launch in VR or Desktop mode could easily append the right flag to the batch file that's kicked off by Build+Test, I think.
serene moat
yeah there's a canny for it, would be very useful especially with Udon https://vrchat.canny.io/feature-requests/p/sdk-option-to-launch-test-build-in-vr-or-desktop
fiery yoke
I think it was put off till the 2018 update...sooooo yeah
hazy galleon
hey, it's time
solid cairn
oh someone made a script for it. I've been using an extreeemely hacky .bat file I put together..
floral dove
@vast nimbus - there's not a specific tutorial for making avatar pedestals, but you can start with the VRC Avatar Pedestal component.
storm copper
how do i make an object activate like an animation?
is there something like hide or unhide function?
something that is this cube
floral dove
@storm copper you can enable/disable the MeshRenderer on the cube
floral dove
you can switch GameObject.SetActive
floral dove
Make a public variable of type GameObject on the controlling UdonBehaviour, and link it to the target GameObject in the inspector.
@storm copper I highly recommend you take a look at the readme in Assets/Udon/Examples and go through the example scenes. It shows how to do the above and much more!
solid cairn
also, anyone come across some weird behavior where your stuff just doesn't get compiled? I had to delete the udon component and add another before it'd register my changes.
floral dove
@solid cairn yep - if you find a particular node or connection that's causing compilation to fail, please let me know! I'm tracking them to fix in the future.
delicate hazel
@floral dove I figure it out.I make a own little program to recive the command and add --novr in the end and run vrchat.
floral dove
@delicate hazel cool - while you're at it, add --enable-udon-debug-logging to allow udon Debug.Log commands to show up in your logs for debugging things that happen in the client.
solid cairn
@floral dove it was pretty much by random, only just starting on the most basic of basic scripts right now. I put my udon component on the same object that had the scene descriptor, added onPlayerJoined stuff for jumping, compiled... nothing. Added the setRunSpeed node, compiled... and the jump worked but the run speed didn't (didn't even appear in the assembly).
floral dove
oh yeah - there's an issue right now that you can't use the same node output to two different places like that unless it's a public variable.
solid cairn
ah okay. I was looking up how to do standard jump stuff and that was the example posted a little while back so I had assumed that bug was fixed.
though it does seem to be working at the moment.
floral dove
@delicate hazel questions about U# should go to the U# Discord, can't help with that here, sorry.
@solid cairn glad to hear that's working! It's been one of my top sources of non-working programs at the moment, but maybe it's not an issue with all nodes.
delicate hazel
@floral dove OK Then. By the way i add --enable-udon-debug-logging . Where can i find the debug.log
floral dove
@delicate hazel they're relative to your user folder in Windows. Something like:
C:\Users\Hammer\AppData\LocalLow\VRChat\VRChat
They'll be timestamped with when the Client was launched like output_log_1-33-13_AM.txt
delicate hazel
@floral dove OK Big thank!
solid cairn
@floral dove So I can clarify, the issue you're talking about is this https://feedback.vrchat.com/vrchat-udon-closed-alpha-bugs/p/udon-graphs-breaks-if-reusing-nodes-other-than-getvariable right?
I wasn't having UIDTOPROPERTYISMISSING show up in the uasm, or having any errors show up in the console, it was instead just not updating the compiled output (without throwing any kinds of errors). That said, do you still believe this is related?
floral dove
@solid cairn - yes, that's the issue I'm referring to. The symptoms may have changed but I 've observed the issue of Graphs just not compiling when node outputs are reused.
solid cairn
gotcha, thanks for the heads up then
obsidian furnace
probably a really basic question but like when i write this with udonsharp i get this error
floral dove
@obsidian furnace questions about U# should go to the U# Discord, can't help with that here, sorry.
obsidian furnace
oh my bad my bad
floral dove
no worries 🙂
flint urchin
@cedar cairn chairs work just fine, there is a little issue with how they're seated however, but hopefully that'll get sorted soon
storm copper
how do i make the plane appear
jagged crow
can an object have multiple behaviors?
fiery yoke
Yes.
solid cairn
so, if we cannot reuse outputs from nodes for the time being, what's the current 'best practice' method of setting run and jump values for a world?
fiery yoke
- You dont want to do it in OnPlayerJoined
thats a global event whenever a player joins. You want that to happen on Start - Use Networking.GetLocalPlayer
solid cairn
sounds good, thanks!
jagged crow
oh start fires when somebody loads up the world, not when the world is first initialized?
jagged crow
hmm
solid cairn
still had to delete the old object entirely for it to update, just switching to start and getLocalPlayer didn't fix the issue.
jagged crow
is there an event to do the latter? or would I have to implement it myself
fiery yoke
There is no event for that, as it doesnt really make sense. It doesnt have many use cases due to technical reasons
@solid cairn You can put the Local Player into a Variable, and then Get Variable
storm copper
does anyone have an appear cube desapear cube program already made?
jagged crow
when would you want it to appear and disappear?
meager dove
For some reason, it seems that vrc_pickup scripts work normally when testing locally, but disappear as soon as I upload a world. Is this a bug, or am I doing something wrong?
fiery yoke
Sounds like someone forgot to change something in the Script stripper.
meager dove
I'm gonna try updating to the suggested version of unity, and trying again
fiery yoke
I was assuming that you are on the correct version yeah
delicate hazel
How can i get VRCPlayerApi when who interact something?
meager dove
updating to latest version didn't fix it!
when I build and test locally, pickups work
but uploading seems to just remove pickups, even if I upload a previous build
jagged crow
is there any way to disable the udon watermark
solid cairn
not right now. there's a ticket for it but it seems to be on the backburner
solid cairn
tame matrix
join order iirc, could be wrong though
cunning mist
@jagged crow While you can't disable the watermark itself, you can edit the image to be entirely transparent. It's UdonLogoAlpha in Udon/Editor/Resources.
proper nexus
Anyone know a way to grab a VRCPlayerAPI from a collision or something similar?
flint urchin
Not right now no. You got to create your own "player" tracking and use that to detect if it's a player or not
jagged crow
ooh thanks vowgan
jagged crow
what have you got so far
storm copper
i tried to do the old way
and i tried to make it on the rotate cube script
the only problem is that it makes the cube itself desapear
the old way dont work anymore
fiery yoke
@meager dove I suspect that the VRC Pickup Script is getting stripped. My guess is that they removed it from the whitelist when first introducing Udon and forgot to put it back in...
jagged crow
@cunning mist this is entirely your fault
cunning mist
👌
jagged crow
😂
fiery yoke
When your Udon Graph doesnt want to compile...Somebody toucha my S P A G E T T
meager dove
@fiery yoke I see! Hope that gets fixed soon!
placid night
Is there a sense of documentation on udon atm?
flint urchin
Wouldn't really help when people don't read the #udon-info channel either 🤷♂️
storm copper
how do i call i value of a variable from another cube
like
have the same value return for both
storm copper
i already did that
still
dont work
ok now i have an error
@jagged crow
i want to mirror the actions from progam 1 to program 2
program 2 will not be interactable
jagged crow
what is the click count for?
jagged crow
oh I thought this was for your mirror haha
storm copper
the mirror is something else im trying to make
looks like im having problems with both
jagged crow
hmm
not sure what the problem with it is
I'm still a total noob to udon xD
I'm working on a mirror script tho, will share it if I get it working
floral dove
@meager dove does the PickupCube in Assets/Udon/Examples/MultiExample work when you Build & Test? That worked last time I checked.
storm copper
i dont know mine dont work as it should
meager dove
@floral dove well build and test always works, my issue is when I upload
floral dove
oh @meager dove, I missed that part. Any clues in the logs?
meager dove
which logs should I check?
floral dove
@meager dove you'd need to enable udon logging by starting VRChat with --enable-udon-debug-logging and then look for timestamped logs under C:\Users\YourUserName\AppData\LocalLow\VRChat\VRChat
flint urchin
@jagged crow you can have the same public names in multiple behaviours
meager dove
alright, gonna be trying that in a bit!
jagged crow
Ooh right I've been confusing public with global
Globals aren't a thing in udon are they
floral dove
@jagged crow - nope, communication is 1 to 1. to do something kinda-like globals, you can do GetComponents and loop through UdonBehaviours that all have a particular public program variable you can set or event you can fire.
meager dove
@floral dove nothing that jumps out in the logs, no exceptions or anything
flint urchin
Debug Log everything!
flint urchin
if it's related to a custom event, just leave the instance blank and it will reference itself
For parents you need a public variable or get the parent then the behaviour on it
jagged crow
nah trying to get the mirror reflection object for the mirror a behaviour is running on
I should be able to pass a self reference to the first param there to get the component I'm after
floral dove
@meager dove can you verify that you can upload the MultiExample scene and that works in the client?
meager dove
sure, let me try uploading that
fiery yoke
@floral dove Can you check if the script is actually whitelisted really quick?
meager dove
the pickup in the multiexample scene does seem to work!
fiery yoke
Then its "spot the difference" time...
meager dove
I will try to make another scene with just a single pickup and see if it happens there too
jagged crow
alright I'm stumped, wat do
getting TypeResolverException: Type referenced by 'VRCSDK3ComponentsVRCMirrorReflection' could not be resolved.
frustrated haha gonna go play alyx for a bit, somebody ping me if you can see what I'm screwing up c:
meager dove
ok so this is really weird, it just started working again randomly as soon as I've added a second pickup
I will try uploading it a few more times to see if that's actually the case
floral dove
@jagged crow it looks like VRCSDK3ComponentsVRCMirrorReflection is not supported in Udon right now, I get the same thing on my side.
@meager dove that's strange indeed - it could just be a recompilation thing. Sometimes it looks like things have refreshed but they don't actually recompile until you make a bigger change.
meager dove
I will try removing the second pickup to see if it keeps working
akso I'm guessing any script in instantiated objects doesn't work right now?
the pickup now works also after disabling the second pickup btw
fiery yoke
@meager dove UdonBehaviour had some problems with being instantiated in the past, dont know if that has been fixed, other than that scripts should generally be fine.
zealous aspen
I'm using Udon# and OnTriggerEnter isn't working for me. I have one collider set to trigger. OnColliderEnter works fine. Is there any special way to do it?
floral dove
@zealous aspen you'll want to head to the Udon# Discord for that 😄
zealous aspen
Alright.
north carbon
soooo, i want to add the "mod" thing so I can jump im my world, im super new to udon and have no clue what so ever on anything about it, any help would be highly appriciated! 😄
please @ me if you can help me with this 🙂 since i might be alseep and i dont wanna miss the message 😄
scarlet lake
how would i apply this?
tiny otter
is udon only for your own worlds or can you affect your avatars in different public worlds?
spare dust
floral dove
@north carbon - here's how to make Jump work in your world!
https://ask.vrchat.com/t/how-to-jump/527
@spare dust - please visit #vrchat-support for general support, this forum is for people making things with the new Udon system.
@tiny otter Udon enables you to build worlds with new functionality. It does not yet integrate with the make-your-own avatar system
tiny otter
thanks for the answer 🙂
scarlet lake
Is vrchat going to make documentation for their main components?
floral dove
@scarlet lake there are some docs, definitely a wip: https://docs.vrchat.com/docs/event-nodes
apologies for the double-post but this gets asked a lot so I want to pin it without the user mention:
Here's how to make Jump work in your world: https://ask.vrchat.com/t/how-to-jump/527
scarlet lake
is there any for networking yet?
floral dove
sure, a few of the components on that page have to do with networking
there's also quite a few networking + sync examples that come with Udon in Assets/Udon/Examples
north carbon
Thanks alot momo! :D
floral dove
@scarlet lake - what are you trying to do with that Get VRC Players graph?
glossy hornet
i wonder how that one guy did the third party cam trick with udon cannot see any way to access main camera
scarlet lake
i want to make it so when i get into the game i can have a custom menu and be able to have like button commands
by game i mean my world
floral dove
@scarlet lake sounds like a cool project! You could make a VRCPickup that has all sorts of commands on it that control your world, sure. Then you could grab it and use the buttons, sliders, whatever. I recommend you start by taking a look at the MultiExample and SyncUI example scenes that come with Udon. The Readme explains how everything works. If you can get that WorldSpace Canvas working the way you want, then you can shrink the whole thing down and make it something you can carry around your world.

long sentinel
how do I destroy something "synced" ? so everyone sees its gone
floral dove
@long sentinel I'd recommend you just deactivate the object instead - instantiate/destroy is not fully implemented on the network. You can use SendCustomNetworkEvent to All to fire off an event on them.
long sentinel
well instantiate works fine, locally, dont see a reason to have it over the network for me.
Im just to confused with events and stuff like that, isthere any example ?
sturdy wasp
I'm not seeing the builder menu in the VRC SDK drop down, just Udon Graph and clear prefs
floral dove
@long sentinel there's some event examples in the MultiExample scene in Assets/Udon/Examples

ah yes, ive been neglecting that, just browsing the ask page, il lcheck it out

Hi, is there any way to disable the ownership of objects so every player can interact with them using colliders (foot colliders)? Right now you have to pick the object up to be able to collide with it
zealous aspen
I've created an interact and it works as it should in local testing, but when I publish it to a live world, it doesn't work at all. Are there any known bugs with interacts?
scarlet lake
how can i use UI Button for Udon?
fallen prawn
Simple VRC Ui Shape?
fair bough
UI Button usage.... First add VRC UI Shape and Udon on canvas
Then... in Udon Script set CustomEvent and back to your button at onClick() set object function to canvas (have vrc ui shape and udon)
set function UdonBehaviour.SendCustomEvent and put CustomEvent Name
scarlet lake
thanks
fair bough
It like Trigger version usage 🙂
you can put multiple customevent in single Udon for your many button 😉
scarlet lake
Just my mistake lol XD
fair bough
don't mind 🙂
oak jungle
Hi all, I have two buttons, for turning a mirror on & off, I'd like to combine the buttons into one but for the life of me it is not working. They work separately. Any help is appreciated.
long sentinel
Any idea on how to show text/images etc on VR users UI? it appears for desktop, but blocks the VRChat menu :/
flint urchin
@oak jungle you need to get the current active state of the game object then unary the bool and use that value to set the active state
oak jungle
I believe I did try that and it didn't work. Using the Boolean Unary right?
flint urchin
Yes
Gameobject isActive -> unary -> GameObject setActive
But do mind that there is a bug that if you’re using the same variable node it will not work (this will be fixed at some point, but keep that in mind)
oak jungle
There isn't a isActive, but there is an activeSelf?
It works, I swear that was one of the things I tried yesterday. (^u^)/ Thanks for helping PhaxeNor.
The next thing I am looking into is a video player, are there any tutorials/guides for Udon's way of doing it?
flint urchin
Video players aren’t supported yet
oak jungle
Ah okay, that would explain mine not working lol
Sorry for being a bother, one more question: How do I enable jumping? In videos they show how to do it in the old SDK and it doesn't seem similar from when I have investigated...
flint urchin
VRCPlayerApi SetJumpImpulse (normal value is 3)
oak jungle
Okay, so correct me if I am wrong, I would add that into a Udon on the VRCWorld with Start > setJumpImpulse?
flint urchin
You can add that anywhere.
Just add it to Start and set it there
I create a manager object and do all the stuff there
oak jungle
Oh okay, that's fine, thanks for clearing that up. You've been a big help!
flint urchin
It’s made so you can update the value at any time
oak jungle
Yeah, it'll be useful in some cases I imagine
glossy sky
So do worlds now have to use Udon or do we have an option to stick with the old triggers? I'm still learning Udon but right now, it's way beyond me and taking me a long time to learn personally as I'm a nursing student who only makes maps as a side hobby etc. x_x
distant ore
is there any node for "or" "and" in Udon?
ionic minnow
why when I import my VRCSDK3 + UDON in the VRchat SDK windows I only get utilities windows ?

How can i Jump with udon...?
acoustic delta
@scarlet lake https://ask.vrchat.com/t/how-to-jump/527
scarlet lake
solved!
acoustic delta
@glossy sky You now get to choose between SDK2 and SDK3. SDK2 is the legacy version which contains triggers, use this if you want to have triggers in your world or if you are making an avatar. SDK3 is the Udon version and does not work on avatars. You must choose one or the other as they are not compatible with each other.
glossy sky
Lovely, thank you!
acoustic delta
@distant ore Yes, for booleans you can use And, Or and Xor. These also exists for other primitives such as ints.
distant ore
Ahh thanks !
acoustic delta
@ionic minnow If you cannot see "Show Control Panel" then there most likely are compilation errors in console. First try restart Unity. Secondly try right-click the VRCSDK folder in Unity and select "Reimport All". If that also doesn't fix it then close Unity, delete the VRCSDK and Udon folders, download the latest SDK from the website, open Unity and try import it. If none of that helps then please screenshot any errors you see in the console. Make sure you have errors being shown as in the picture. You can also find Unity errors by scrolling to the bottom of your "Editor Log" which you can find by the green arrow:
ionic minnow
yeah i got this
acoustic delta
@ionic minnow Those lines of code should only run if you are on SDK2... Are you making an avatar or a world? Could you please try close unity, delete the VRCSDK and Udon folders and re-import the SDK? You should have version VRCSDK3+UDON-2020.04.01.10.20
ionic minnow
Im making a world and im using VRCSDK3+UDON-2020.04.01.10.20

Hello, I have a question, shouldn't we use udon behavior in the vrc world when making jumps using udon? I remembered using player mods and put udon behavior in the vrc world, but the jump didn't work. Is this an error? Or shouldn't udon behavior be used in the vrc world?
acoustic delta
@vague agate Yes, if you are using SDK3 then you need to write a small script activating jump in your world.
https://ask.vrchat.com/t/how-to-jump/527
vague agate
@acoustic delta Thank you so much for your answer ~! When writing small script activating, shouldn't we put this udon behavior into the VRCWORLD prefab? Shouldn't it be like using playermods? Does any udon behaivor not work on VRCworld prefab?
ionic minnow
@acoustic delta I tried to reupload but I still got this error
fallow mural
is there a reason I can't save the clone into a game object variable? each time I do this link when it compiles it gives me the error ```Failed to refresh program 'Spawner Udon Graph Program Asset 2' due to exception 'System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

@vague agate You are right, such script could definitely be made into a drag-and-drop Prefab. I think various reasons I haven't seen such prefab yet is 1) it's such a tiny script and easy to recreate, 2) Udon hasn't existed for a long time, and 3) it's a good way of yourself getting started working with Udon.
tardy trellis
how do you like, actually do "get" from a list? like from this thing, or do length?
acoustic delta
@fallow mural I have gotten that error a million times with my old graphs. It seems like creating a new graph file and copying the nodes over fixes it. Does the error go away if you remove that specific line you mentioned? Make sure you aren't re-using nodes anywhere else in your graph, which is a bug they fixed recently but haven't released yet.
https://vrchat.canny.io/vrchat-udon-closed-alpha-bugs/p/udon-graphs-breaks-if-reusing-nodes-other-than-getvariable
@tardy trellis As of now we only have access to Arrays, and we can't do anything with Lists. That is a known bug.
tardy trellis
then.. how do you get an array of all players?
fallow mural
@acoustic delta yes it goes away if I remove the link, it seems if I link ANYTHING to that clone it will rip, even a debug. I remade all nodes from scratch, seems that fixed it O_o thanks
I enter playmode, test it, doesn't do anything, when in playmode I get these, don't know if they are normal.
When I exit play mode, I get that error again 😐
Already created the program from scratch on a new file, no luck
vague agate
@acoustic delta Thank you very much for the answer.
But my question wasn't about it.
I'm not good at my English so I'm asking a question while using a translator. Sorry.
I tested the link about the jump you sent me a while ago.
When I tested it before, I made the script in vrcWORLD. But the jump didn't work. And when I made it inside empty instead of vrcWORLD it worked.
So I thought the udon script didn't work in vrcWORLD (prefab-add component-udon).
So I was asking if I was right.
And I tested it again after rebooting the computer. And the jump worked well. I think it was just an error.
Now the problem is solved. I'm really sorry for the misunderstanding. And thank you very much for your help🙂
distant ore
Is there a way to parent an object to the head bone of a local player?
fallow mural
anyone has some udon sharp examples? I'm stuck at finding the instantiate a prefab
fallow mural
thanks!!
west plover
Look for the VRCInstantiate function
I literally just put it up 😄
I think Merlin added some examples to their repo too
meager dove
@distant ore you can just get the head tracking data with the vrcplayer api get tracking data node
west plover
Cardmanager.cs::285
meager dove
from that you can get position and rotation and apply the necessary transforms have an object follow the head
west plover
Can you do that with hands?
meager dove
yes, the same node lets you get head and hands data
west plover
neat.
distant ore
Would it be the same as using VRCplayer API Get Bone?
meager dove
I would guess that the tracking data is exact controller and headset tracking data, while bone position is going to depend on the armature!
tardy trellis
i tried doing tracking data thing, but it doesn't work.. am i doing something wrong?
by logic the object should just lock onto my left hand?
but it floats there, possibly the thing doesn't even tick
halp ;-;
oh oof
there's an error when i use tracking data
ivory thorn
Did someone already make any basic udon tutorials like recreating triggers etc?
lusty lintel
flint urchin
Working on it
ivory thorn
Thank you for your service, udon cannot be less user friendly imo 😛
flint urchin
Oh, I’m aware 🙂
tardy trellis
udon reminds me a bit of unity bolt tbh
flint urchin
Also for your issue, multiple output from a node can cause issues currently until the bug has been fixed
You should also use the combined set transform and rotation node when updating it like that
vast nimbus
Can anyone make a exemple of who to make a avatar pedestal on Udon, i try but not work
flint urchin
That node is better to use in terms of performance
At some point during the day I will william
@tardy trellis use this node instead of the two you have https://docs.unity3d.com/ScriptReference/Transform.SetPositionAndRotation.html
tardy trellis
okedoke
but also, i figured out that tracking data is just not working and bone position and rotation works, but now i want to also display bone position... it doesn't work for some reason D: am i doing something wrong? (reference to uitext is set in the editor)
flint urchin
Is this object a child object by any chance?
tardy trellis
yeah
flint urchin
Okey, then until that bug has been fixed you either need to have it as root, or have a behaviour on all objects up including the root
tardy trellis
flint urchin
So the behaviour is root
Hmm
I’d suggest you do debug log and see if it’s being fired in game
tardy trellis
how do i see logs from inside vrchat tho?
flint urchin
—enable-debug-gui —enable-udon-debug-logging
Then press eighth shift + \ + 3 if you’re using US keyboard
You can see this in both desktop and vr
Just be sure to remove those launch options when you play normally
tardy trellis
uhm, i press build & test in the unity and not sure i can really change launch options while doing that? or is that automatically done by that button?
flint urchin
You can, but requires some extra stuff.
Don’t have the url or code for it here now (on mobile)
So recommend you upload and start from either steam (if that’s what you use) or a shortcut with those launch options
tardy trellis
oke

Are objects able to make collisionchecks with the player? I tried this and it does not work https://ask.vrchat.com/t/player-collision-in-udon/428
oak jungle
Do I need to do any Udon for VRC chairs?
fiery yoke
@robust summit I wrote that guide a few weeks ago, and I tested it. It was working back then. Might have changed, but I dont think so. Theres potentially a much better way by just using "OnControllerColliderHit" but I havent gotten around to testing that yet
boreal flower
Hello, I'm really new to Udon and i'm trying to figure out how getting components from other objects work without setting them as public, any reference to a video or a push in the right direction would help, thank you!
acoustic delta
@cedar cove At the moment, you can't. Opening one graph will close the other.
cedar cove
Ah ok, thanks!
flint urchin
@boreal flower GetComponent can do that for you
boreal flower
Thanks, but it looks like it uses components that already exist on the object to get other components? I don't have any of those components on the object already
I have a child on the object i'm using, and there's an audio source on the child. I want to get that AudioSource component without setting it as public
I thought about using GameObject.find(name) but I don't know where to go from there even if I found the object
robust summit
@fiery yoke will try and figure it out later. It apears to work while in the editor but not when you test it localy in vrc
fiery yoke
That might be unrelated
mystic lodge
Hey! I would like to ask you for help with my card, I am modifying it and I would like to play games and if you could tell me how we make beer pong please
distant ore
Can we somehow figure out a player's height ?
flint urchin
Get the player position and the position of the players head, that will give you a rough estimate of their height
fiery yoke
@robust summit I can confirm that collision with the player still works
distant ore
So if a player is crouching then the height wouldnt be accurate?
is there a way to check if a player is crouching or not then ? 🤔
fiery yoke
You essentially just get the difference between their base height (between the feet) and the Headset height. This can be any number, because of physical moving (crouching, jumping) and Playspace mover.
There is no way to get the "actual" height, because there is no "actual" height. The only fixed values are the "User Real Height" and each Avatars height when in T-Pose. But even then it depends if youre just measuring the armature, or the mesh.
For what exactly do you need the height?

Is it just me that is having a weird bug with Chairs? Sitting on them then your avatar like stretches their legs

They are a bit weird atm, you tried the default example chair too?

I've been trying to use GameObject.GetComponent to get the UdonBehavior off of an object, then I'd like to send a custom event to that UdonBehavior. When I do this, I get an error.
The generic node '__GetComponent__T' doesn't support the type VRC.Udon.UdonBehaviour; Consider using the non-generic form of this node if it's available
I've tried using the other forms of GetComponent, but I can't connect the output noodle (which should be an UdonBehavior) to send custom event.
flint urchin
post image of how you have it now
floral dove
@lilac mountain - I ran into this bug myself. I had to connect the noodle using one mode and then switch it. I'll try it again and see if I can reproduce.
lilac mountain
floral dove
@lilac mountain - ok, it's a bit silly, but this works:
Set your GameObject.GetComponent node to use (T) in the dropdown, connect the output to the SendCustomEvent node, then swap the GetComponent node to use (Type). It should stay connected and work now.
lilac mountain
it works, thanks!
oak jungle
@flint urchin Yeah the default chair is messed up lol

I currently have a script using onTriggerEnter on several like objects to teleport the player when the object enters a trigger cube I have set up. This means I have multiple objects each with a script on them.
Are there events that would allow me to instead listen for collision/triggers from the trigger cube instead? I tried a few different ways with no luck.
fiery yoke
Well you could setup a system to do that.
So what exactly is your goal?
solid cairn
so what I have works:
but I need to place that on each of the objects. (I have multiple objects able to fire off a given event when entering the cube).
That results in quite a few objects with udon script components, and I was wondering if there was an event I can use from the cube's side instead to listen for objects entering it, so I won't have to have, say , 10 objects with scripts, and instead only have 1.
fiery yoke
You pretty much already have that logic tho dont you? Just invert it
solid cairn
yeah, I had that on the cube, but it wasn't firing
so I was thinking I was just missing something basic
fiery yoke
Well collision like this is always two way. It causes a OnTrigger/CollisionEnter on both GameObjects.
You might want to read up on Collisions and when they happen
solid cairn
hmmm maybe
lusty lintel
what parts about vrcstations work? the default chair work for entering. but on my end it clears the controller, and setting it with udon will render the station in unusable.
gaunt fern
I need some help. I keep getting this error whenever I try to compile a graph. The graph used to compile, but when Unity2018 and Udon hit the live servers, I updated the world and now it won't work. I thought it was a bug with just that graph. So I completely recreated the graph from scratch and still got the same error. Everything in the error was the same. I did a few things and found that it's being caused by a branch node. The node before it is another branch node. At one point I put a SetVariable in-between them as a buffer, but still got the error. If anyone has any ideas on how to fix this, please let me know.
fiery yoke
@gaunt fern Most "KeyNotFoundExceptions" are currently caused by a bug that has to do with nodes and using their output for multiple node inputs. You could try to avoid doing that, wait for a fix, or use other compilers like U#
solid cairn
that bug's making me miserable :/
meager dove
how does object syncing work exactly? just adding an empty udon behaviour script with synchronize position works?
floral dove
@meager dove - that's right! Synchronize position will update position and rotation.
meager dove
is it supposed to work with instantiated objects right now? they don't seem to sync
floral dove
I've seen the system be a little unhappy about completely empty Udon Behaviours, though. There's an 'Empty' Udon example program in the SDK you can use to avoid that.
fiery yoke
Instantiated objects are not networked rn, syncing is a network thing. So that
statement doesnt make much sense.
floral dove
Sorry, @meager dove - Instantiation does not sync right now.
meager dove
oh, I see!! thanks for the help!!
fiery yoke
Also momo, you still need to join the Team Member group on the Ask forum ;P
placid musk
Is it worth me reporting a bug if I get an error before I even open the Udon Graph?
It gives me a UnityException when I try to create a new program.
floral dove
@placid musk possibly, but let's try to work through it first. Is this issue happening in a new project or an existing one?
floral dove
oh wow, super-clean. I have no insights, then, other than the usual suspects - try restarting your machine, making a new project etc. Make sure you've saved your scene before trying to make the new program.
placid musk
it says "UnityException: Creating asset at path failed."
it doesnt seem to have a folder to place files in
theres 2 spaces inbetween 'path' and 'failed'
floral dove
aha. Try opening up one of the example scenes in Assets/Udon/Examples and making a new Behaviour there.
floral dove
@placid musk where did you save that first scene?
mortal pelican
just started learning Udon and thought to build a couple instances of the demo UI scene, but nothing seems to be syncing so wondering if I just didnt set it up right or something?
placid musk
@floral dove i didnt. im not going to worry about it though, it didnt have anything in it except a cube
floral dove
@mortal pelican most of the values will only sync from master > others. Did you go through the Readme for this scene? It explains what's going on with each item.
@placid musk - ah! That's the problem then. You can only create Udon Programs in saved scenes, that's how Unity knows where to save them.
placid musk
ooooooohhhh
grizzled shuttle
I've just jumped into udon, I've found this Vrcplayer API Get All Players node, which gives a List'1 which I assume is a List<Vrcplayer>. The problem is this isn't a Vrcplayer[] so I'm not sure how I'd go about iterating over it.
https://owo.sh/6mqTTPW.png

lol okay ty
grizzled shuttle
(i'm trying to get the display name of the instance master)
floral dove
@grizzled shuttle on a call right now, but I think this could work:
fiery yoke
Does anyone know what Networking.GetUniqueName() does?
floral dove
@grizzled shuttle just tested and it works. Instead of getting a list of all players (lists don't work right now), we just call this method on Start, which means it runs on everyone in the world when they first join and checks if they're master. You could have this on a world object instead, fire it off with a custom event, and whoever is master would have their UdonBehaviour report 'True' in that Branch node.
ionic minnow
Someone get a udon graph for a trigger button to activate/deactivate a props ?
floral dove
@ionic minnow the example scene at Assets/Udon/Examples/MultiExample shows how to use a Button to send a custom event to another object, you could use that to activate/deactivate another object. Check it out, and the Readme that goes with it in that same directory.
ionic minnow

NP! Anyone have an example or know what node I'd need to update text in the world (via any working text system)?
flint urchin
To a ui text?
rotund needle
Sure!
I see a node for that, I think. But I'm not sure how to 'get' the component. Can I just make a var for the Game Object that has a UI Text component attached?
Might have found a post about it on ask.vrchat

wind atlas
How would I go around making a global timer? Is it even possible?
As far as I understand it, Synced Variables are on the server, but you can only trigger them when somebody joins?
flint urchin
Global timer, as count up/down?
flint urchin
Just have a synced INT variable and update that on the master side
flint urchin
Then you use the OnDeserialization to update the value on remote clients
flint urchin
It’s the event that is fired when a synced variable is updated
It doesn’t tell you what variable though
wind atlas
Hmm. I thought variables are synced automatically.
wind atlas
Ah, so each tick it gets called?
flint urchin
It get called when there is a update to the variables
OnPreSerialization is before the variable is synced.
Master updates the timer in Update
Remote clients in Deserialization
Can be done in update too but
Yeah
wind atlas
Thanks a lot.

@floral dove Sorry for the delayed answer haha I went to bed. (I beat Alyx! :D)
Do I need to wait for an udon update to make a mirror toggle then? Or is there some other way of going about this
glossy hornet
is there any way to access the player cam? ive seen a world with different camera perspectives made with udon cant figure out how it works 😮
floral dove
@jagged crow no worries - and congrats on beating Alyx! I've only played a few hours so far, too busy with 2018 launch :P
I think you could get around the issue by just turning on and off the GameObject the mirror component is on, or even just the renderer component.
sour pendant
im wondering when the performance issues will be patched
I have no idea why but i mentioned this a couple days ago aswell
i have a 9900k with a 5.2ghz oc on all cores an rtx2080 and 32gigs of ram
my game is locked to 45 or 30 randomly with mirrors OFF
i really dont understand why
rotund needle
in VR?
rotund needle
Sorry if I'm repeating something you've already discussed, but if it is a single frame under 90, it drops to 45
sour pendant
it worked before the update
that isnt the case
ive never had problems running the game
or any game with this pc
it seems to just be some bug
another friend has his game locked at 15
no clue as to why

@sour pendant support questions can go to #vrchat-support , this channel is for people learning to make things in Udon.
sour pendant
it wasnt really a support question
was asking if there was a patch in the works
but i understand
scarlet lake
anyone figured out client side hit detection a la steel n gold on guns yet?
slow coyote
Anyone have an idea on how to detect if the local player is colliding with a mesh collider (and if you can get the object it's colliding with)? Like is there a known way to get access to the player's avatar's bounding box?
I was trying to make some kind of wall kick/jump mechanic and was aiming to just do some ray or spherecast with the tracked hand data, but then I realized that wouldn't work with desktop users.
jagged crow
Hey so if I leave an instance input null, will it always automatically fill in the instance of the running program?
or will it only do that if the type is UdonBehaviour
floral dove
it will do that for GameObject, Transform and UdonBehaviour
for anything else, you'll want to set a variable or do a GetComponent
jagged crow
ahh gotcha
I guess all I really need is the GameObject anyway, everything else can be grabbed from there
iron shuttle
I was curious is its possible to force a avatar on a player
floral dove
@iron shuttle doesn't sound like a very nice thing to do
iron shuttle
i would be for a gamemode
jagged crow
if not abused it could be cool, but it'd 100% be abused lol
maybe a feature to preemptively give permission for specific avatars 🤔
iron shuttle
i would be nice not to see anime in a world for once
jagged crow
pff
floral dove
@iron shuttle - you could offer up a pedestal and ask that users switch to play the game, or give them a good reason to do so.
iron shuttle
maybe but then i would need to make a indicator that they are a curtain role if they dont
floral dove
@slow coyote - you can't get collisions from player avatars with Udon, but I think you could have a player hold an object and look for collisions on that.
jagged crow
ayyyyyyyy 🎉
floral dove
yay @jagged crow
iron shuttle
or check if the avatar is being used by the player so they can do something that other players cant
is its even possible i really need to read up on the documentation for it
floral dove
@iron shuttle Udon doesn't currently interact with Avatars
jagged crow
I'm confused though, the way I did this shouldn't have worked. Deactivating a GameObject disables each component, including attached renderers, colliders, rigidbodies, and scripts. For example, Unity will no longer call the Update() method of a script attached to a deactivated GameObject. (from https://docs.unity3d.com/2018.4/Documentation/ScriptReference/GameObject.SetActive.html)
Shouldn't it have stopped listening for my custom events after it was deactivated the first time?
slow coyote
Thanks for the answer, momo. Was hoping to avoid doing something like holding an object, but oh well.
jagged crow
or do udon behaviours keep running while deactivated
floral dove
sorry @slow coyote - support for making Avatars with Udon programs is down the road, maybe there will be some more straightforward options then.
slow coyote
okay, I apparently have a new question already 😓
I don't know what I clicked on, but instead of seeing the normal udon behavior component.. I'm.. seeing this and I don't know how to switch it back.
iron shuttle
thats kinda weird that you cant do anything for changing avatar of course it would be abused but i think you could see alot of cool things from it.
jagged crow
@slow coyote remove the component and add a new one I guess haha
then put the behaviour back on it
slow coyote
Happens everywhere in the project
slow coyote
I created a new scene, new object, and I get this
floral dove
@jagged crow - Custom Events will still fire on Deactivated Gameobjects! The usual suspects like Update, FixedUpdate, LateUpdate etc will stop firing but CustomEvents will get through so you can safely use an event to reactivate the object.
jagged crow
ohh interesting!
floral dove
@slow coyote - looks like the SDK is not loaded properly in that project. I suggest you reimport the unitypackage.
jagged crow
so if I'm throwing custom events at an object on Update, deactivating that object won't help performance
good to keep that in mind
slow coyote
Oof. Alright, thank you.
floral dove
@jagged crow - yep, that's right.
jagged crow
I guess whatever logic I'm using to deactivate the object could also set a flag to make it stop sending events
now I just need to figure out what I want to do for my first proper project 🤔
floral dove
@slow coyote - I got a helpful tip regarding PlayerCollision from @fiery yoke! Take a look at this article they wrote: https://ask.vrchat.com/t/player-collision-in-udon/428

fiery yoke
@slow coyote You also somehow managed to get the Debug Inspector information in the normal Inspector. I have never seen that before lol
iron shuttle
has anyone attempted a inventory system yet?
slow coyote
I don't know what I did exactly to have that happen, Helpful. I had just did a build and test thing, then clicked on a public variable checkbox, and suddenly it transformed
fiery yoke
That is definitely strange. As I said, Ive never seen that happen before. Try going in and out of the debug mode of the inspector
slow coyote
Tried it a few times. Nothing changes
(well, other than how it looks when inspector's in actual debug mode)
fiery yoke
You must be cursed then. No idea how that happened.
slow coyote
Curse you, curses!
May as well report that reimporting the SDK does bring back the proper udon behavior component functionality
floral dove
@slow coyote - I've seen this happen when I'm messing with SDK importing a lot. Exit Unity, delete Udon and VRCSDK Folders, reimport package. You should be good to go.
oh good 🙂

grizzled shuttle
Is setting animator triggers broken in udon?
glossy hornet
how to access player camera on udon?
fiery yoke
Short answer: You cant.
glossy hornet
ive seen a udon world that is selling the script for third person view so there must be a way
flint urchin
It’s a shader and a render texture
glossy hornet
but its enabled with different keys and positions
fiery yoke
I think they are using an extra Camera that is rendering to a RT. Essentially the actual player camera is not used.
flint urchin
Because it’s using a second camera in the world that sends the images to the render texture, which is displayed in full screen with the shader
glossy hornet
the world is called Udon (Desktop) - Third Person Camera maybe you want to take a look at yourself when you got some time
flint urchin
We know how it works, that’s what we’re telling you
glossy hornet
so its just a shader with hotkeys bind to it?
glossy hornet
so its made with a second game aplied a shader to it and make the cam move with udon on keypress
flint urchin
It’s a bit more complicated than that but essentially yes
glossy hornet
sounds like very bad performance because the game has to rander 2 cams instead of 1?
render*
flint urchin
That all depends on your world and what type of avatars are being used
glossy hornet
would like to have some kind of rts camera for my project idea
but i guess maybe with a shader thats a pretty bad idea, cause it will propably not work on vr headsets and cost a lot of performance
i was hoping i can controll the main camera inside udon itself
flint urchin
It will, just got to write support for it
But don’t recommend using third person for VR
floral dove
@grizzled shuttle Animator Triggers work if you use the name of the trigger instead of the index.

This is my first 2 hours with udon so I don't know best practices yet
my animator is very simple https://owo.sh/3PLR5ek.png
fiery yoke
Ahh sorry yeah that should work. But you dont need that branch at the start.
floral dove
@grizzled shuttle Udon doesn't like sending one output to two places right now - I see you've got that twice in your graph.
that may not have anything to do with your issue, but not knowing what else is going on, it's a decent place to start.
fiery yoke
Thats not always the case momo. There is a few cases where it wont compile, but then there is other cases where it does.
floral dove
@grizzled shuttle are you getting the logs you expect?
grizzled shuttle
I was getting the logs I expected, but the sending one output to two places is what was doing it
I made everything have one input and one output and it worked
fiery yoke
Thank god

haha fix is here @fiery yoke ! This unholy mess now works just fine.

I see alot of people asking about making Avatar Pedestals. But no actual replies. Anyone got the rundown on how to do this in UDON? I've been able to make teleporters, doors, mirrors enable on trigger enter/exit, spawn notifications, etc. But can't get Pedestals working in any meaningful way. I'm honestly a tad surprised they didn't at least include code for all the basic things to help people with growing pains instead of a spinning cube.
floral dove
Here's how to make an Avatar Pedestal:
- Add a VRC Avatar Pedestal Component to a GameObject in your scene and fill in the fields - Set the Blueprint Id to the Avatar you want to display, and turn on ChangeAvatarsOnUse.
- Make a new UdonBehaviour with the attached graph.
- Build & Test your scene to see it working.

Possible to print Display Name of Master of world into a UIText or other 'display' in world realtime?
- When 'Host' of world Joins their name is displayed on a (billboard, poster, etc).
Would this involve setting gameobject(s) active with alphabetical or numerical statements, etc. OR a simple 'print' function to text document in world.
^^
fiery yoke
@urban pivot Yeah you would want to do that with the UIText.set text node
urban pivot
Okay, when doing this where would I plug it into for it to appear in scene for instance. --
I have a canvas with UI Text currently.
@fiery yoke
fiery yoke
You probably want a UIText variable, that you put your UIText object in. Then you use that as a reference.
urban pivot
Okay, I would create a 'UIText' variable in the Node. Would I name this especially something? Would I throw the entire Behavior Script under the Canvas?
This is what I have currently;
ionic minnow
someone get a udon graph for jump in world ?

in the VRCWorld ?
ionic minnow
like this ?
acoustic delta
@ionic minnow Yes, @urban pivot is right, the jump impulse script you can just put on an empty game object in your world. If you set it to 0 they will not be able to jump.
ionic minnow
so I set it to 1 or 2 ?
urban pivot
yup
acoustic delta
I have seen recommendations on anything between 1-3, it changes how high you jump, and is up to personal preference.
ionic minnow
like that ?
acoustic delta
That looks right

@fiery yoke I plugged the Text from the Canvas into this Variable, will this give the desired result?

Probably not quite. Im not at my pc right now, I might show you how to do it properly later. Otherwise youll have to ask someone else

Is making a dungeon hak n slash world with monsters realistic with Udon? with sword/bow (maybe more) did anyone do it yet?

@urban pivot To update UIText objects you need the "UIText set Text" node:
The UdonBehaviour script does not need to be under the canvas, it can be anywhere, on an empty game object. Just assign the UIText object to it's public variable.
urban pivot
Okay! thankyou

how can I do a remainder operation on a long...
acoustic delta
That seems to be missing, please make a canny about it. @hazy galleon
hazy galleon
booo
acoustic delta
Meanwhile you can do like we did with int before remainder was implemented, where:
a % b
# i.e. 5 % 4 = 1
# can be written as:
a - (a / b)
# i.e. 5 - (5/4) = 1, because (5/4 are both ints and therefore always round down and become 4)
@hazy galleon
hazy galleon
a - ((a / b) * b)
urban pivot
@acoustic delta When recreating what you've shown above it creates this; Correct? Then would I plug the Text from the Canvas into this to complete it? I'm not understanding the connection between code and scene.
acoustic delta
Yes.
hazy galleon
what I'm actually trying to get is fraction of day though, maybe I don't need to do this
.NET just has such bad APIs for time
acoustic delta
We are also limited to which classes we can access, for security reasons. I know some Timezone stuff were missing last time I checked at least.
urban pivot
It's plugged in, but when I check the Text on Canvas it doesn't populate with 'hello world' like defined.
hazy galleon
so far so good about getting the time zone, the only problem is that .NET has a dumb idea of what time zone IDs should look like
so you have to go digging in the registry to find the time zone
acoustic delta
@urban pivot What do you mean with "but when I check the Text on Canvas"? Did you press play for it to run? Are you getting any errors in console?
hazy galleon
...and I guess you have to hope that the user will have that zone on their computer too
the good news is that when running on non-windows, it does use the standard olson time zone IDs
urban pivot
I did press Play yes, I am getting errors. I'm getting the same [UdonBehaviour</color>] An exception occurred during Udon execution, this UdonBehaviour will be halted. VRC.Udon.VM.UdonVMException: The VM encountered an error!
acoustic delta
@hazy galleon Seems we have access to both SystemDateTime.ToLocalTime and SystemDateTime.ToUTCTime
@urban pivot Please press on the error in your unity console and copy/screenshot the full error.
hazy galleon
neither of which is the one I chose to use 🙂
urban pivot
@acoustic delta
hazy galleon
currently I'm at TimeSpan wondering how to get it as a float
acoustic delta
It complains that the myText variable is not set, or not connected. Can you please screenshot your graph?
acoustic delta
@hazy galleon We don't have access to the TimeSpan class at all. You can't use any of it's functions.
acoustic delta
Although what you can do is pipe the TimeSpan object into a "Object To string" node and get a string representation of its value, that's something you can at least work with. @hazy galleon
hazy galleon
and then I'd have to parse it :/
acoustic delta
Yes.
I used a similar approach when measuring how long my graph took to run:
By setting measure to a DateTime.Now at the start of the graph, and then running the above code at the end of it. Even though we don't have access to TimeSpan class it's still possible to pipe it to an Object input.
hazy galleon
problem is that I want the actual value of the span as a float
so it's annoying
there's another annoying way to get it, where I get the hour, minute, second, millisecond, etc. and build it up manually
at this point it's easier to stick with SDK2 and using a panorama to get the time
urban pivot
This is what I'm attempting to do- Grab the display name and Push it onto a UI Text in scene / world.
acoustic delta
That graph should work. Make sure the public variable DisplayNameOnJoin is set. The "Object reference not set to an instance of an object" means it was trying to perform an operation but the "instance" input node was null i.e. not set.
urban pivot
Are you talking about 1, or 2?
And then when it's done grabbing both, how would this than be put into the UI Text
Okay ' Hello World' is now printing.
And is printing the welcome message! 😄
acoustic delta
Good job!
hazy galleon
hmmmmm
so the dumbest thing here is manually casting int to float when not even C# makes me do that
but other than that I really don't think there's much more I can trim off
it would have been nice if addition let me put in more than 2 inputs
urban pivot
@acoustic delta Is it possible to convert a Int to a string? Should I use a Get Value function; or how would I convert the int to readable string?

I had the same issue. I don't think they're working

does anyone know if pickup events are firing?
tryign to make an item snap to whole number coordinates and they don't seem to be triggerign at all or i'm donig it wrong
this is my current graph, it should take the existing position and round the X and Z values to whole numbers. I added the Update looop just to see if it was donig anything.
i may have it setup wrong or something, i'm not sure
i have these on the parent object, and the object itself is extra simple:
fallow mural
the pickup events seem to be firing, at least in undon sharp @winter gust
winter gust
do you think my graph is wrong then? maybe i'm usign the wrong order of operations here
or do i need to manually set the transform now? i understood from the intro videos the transform and object tuff should referrence itself
fallow mural
I haven't really used the graph it was giving me problems, do u get the log on the debug log?
winter gust
no, nothing in the console
unless it writes to a file somewhere
this shows up in console sometimes while i'm editing:
"Failed to refresh program 'NiteEengale (1) Udon Graph Program Asset' due to exception 'System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary."
fallow mural
idk if this is the issue, as i said didnt try much with udon. try creating a public variable, but dont drag anything to its slot, it defaults to the transform of the same object, then Get that variable and link to the first block, the transform get position
winter gust
i think it's failnig to compile
some node seems to be preventing it
after i added the public variable it didn't show up in the inspector
wheat grove
I'm not sure if this is the right place to ask, but I noticed that in Udon worlds such as the Foobar Udon Arcade, the games, objects and text don't show up in the Stream Camera. Is that by design?
winter gust
ok
so apparently i can't use events at all
putting one in the graph, compiles ok, as soon as i attach it to anything, compile error in console
"Failed to refresh program 'NiteEengale (1) Udon Graph Program Asset' due to exception 'System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
"
yeah it's just broken entirely for me
i can't connect any event nodes are it fails to compile with that Dictionary error
cool
acoustic delta
@urban pivot Yes, just do "int To string" node. You can always cast anything to a string in Udon/C#.
@winter gust Make sure you are on the most recent version of the SDK, version VRCSDK3+UDON-2020.04.03.13.19. They recently fixed a bug where re-using nodes caused the error you are getting, and which I can see you are doing from your screenshot. https://vrchat.canny.io/vrchat-udon-closed-alpha-bugs/p/udon-graphs-breaks-if-reusing-nodes-other-than-getvariable
winter gust
i will double-check that in a moment
version is old, updating
i'll seeif the issue remains, otherwise i'm swtichnig to udonsharp for now
welp, i'll try it some other time i guess
the graph doesn't load and i have to remake it
ok i'm finally to a point where i can test
had to update the udon sdk, and the restart unity
floral dove
@winter gust you can't connect two flow nodes to one input like you have. Flow decides the order of execution.
floral dove
You can check out the examples in Assets/Udon/Examples to see the graphs for some working pickups. We don't have anything working with OnDrop but maybe it will give you some clues about how things are set up in the scene .
normal lichen
anyone know how to fix this?

@normal lichen check your sdk is updated
i just had that issue, but haven't been abl to verify it went away after i updated
latest version is here: https://vrchat.com/home/download

Hello, I'm trying to put a gameobject active for everyone when I press a button, it doesn't seem to work globally, am I doing this wrong ?
normal lichen
@winter gust thank you i updated the sdk and it dosent do it anymore
winter gust
good to know
it invalidated my graph so i would have had to make it again
@floral dove so @fallow mural and i have discovered that the stations aren't triggering onenter and onexit events
of the exposed event aren't named correctly
*or
floral dove
@winter gust yes, that's a known issue. Working on it!

cool thanks for your hard wrok
keep it up and we'll have some cool stuff to build here

Hello. Does anyone have a good guide/tutorial for Udon? I'm trying to make an item respawn to it's initial location on the press of a button, something that I did very easily with the old trigger system, but I don't know how to find the proper components for the graph and I'm stuck...
floral dove
@scarlet lake I recommend you check out the examples and readme in 'Assets/Udon/Examples'.
You want to:
On Start, save the position of a Transform to a Vector 3 variable.
On Interact with Button, set Position of Transform to this saved variable.
floral dove
Hm - your graph looks pretty good from here, no clear issues off the bat. I can try to replicate this later today. It's possible that triggering the Exit Station event doesn't currently work. There's a known issue that the onEnter/onExit events don't fire, could be related.

Have you updated to the most recent sdk? There was a problem with pulling multiple noodles from one node like that, but apparently this update has fixed it
plain elbow
Does anyone know a way of getting an int with the number of players currently in the instance?
flint urchin
We will be able to get it via the list of players when that has been fixed. But for now you got to do the math in Player Joined and Player Left
plain elbow
So something like OnPlayerJoined add to number and OnPlayerLeft subtract said number.
im a dummy
thats so simple
Also separate question; how do i access a public variable from a different udon graph?
flint urchin
GetProgramVariable

anyone know how to make a line break in a string?
floral dove
@plain elbow not yet - I've tried so many things.
plain elbow
I figured out another way to try to make line breaks, its pretty janky but it works--just add a boatload of spaces and the next word will move to the next line.

Haha that's exactly what I do in the SyncValueTypes example @plain elbow. Didn't want to recommend it because it's JANK

What is the difference between OnSpawn and Start when you join?
west plover
I'm getting a multi-minute freeze on "Bundling and compressing data"
When trying to upload
scarlet lake
@scarlet lake I recommend you check out the examples and readme in 'Assets/Udon/Examples'.
You want to:
On Start, save the position of a Transform to a Vector 3 variable.
On Interact with Button, set Position of Transform to this saved variable.
@floral dove Thanks for the advice, but I'm having a hard time in finding the proper block. I've managed to find Start, but how do I get the positions of a transform? By using "transform get local position"? I can't link the start block to that, which probably means that I'm doing this wrong. It seems to be asking for an instance as an input. I guess that instance is the item that I wish to respawn, but how do I input it to the block? Do i need to copy some string into the inspector tab when clicking on a block?
I'm sorry for these noobish questions, but sadly I have 0 experience with coding. I could manage myself in the old system because stuff like "spawn" was self explanatory, but Udon's block's names are rather cryptic for a guy with 0 experience in programming like me 😅 If i type "transform" into the search bar, I get a very long list of results, and I don't know exactly what is that I should be looking for.
Could someone be so kind to upload at least a picture of what am I supposed to do? I have a friend who runs language learning gatherings on VRChat, and I made a simple cozy world for him where he could play basic language games with his students. He asked me to make an update for the upcoming Easter, for being in theme with the festivities. I had a button that could respawn a dice that we used for a conversation game. But if was able to do that by myself with the trigger system, Udon is on a level I can't access, so I can't "rebuild" my world with the new SDK or I'll loose that button and the chair toggles I had 😅
Thanks in advance for who can spare some time to help me.
floral dove
@scarlet lake have you gone through all the examples? I think if you follow the readme and go through the example scenes and graphs, you'll learn a lot about what blocks are available and how the program flow works. If you do all of that and you are still having a problem, I will help make your graph for you in a couple of hours when I've got some free time.
scarlet lake
I've read the readme and tried to open some examples, and then I felt... not qualified enough for understanding it 😅 I loved the video tutorials found in the readme, but they take for granted that the watcher knows a lot of stuff... I don't think I do. Either that or I'm dumb. 😅
For instance, in the tutorial video they show that using a node called "transform" they can store the data of a cube in variable. The thing is, I sense this is what I'm looking for, but I don't get how to decide which object that node is taking data from. And what data exactly. Does it reference to the object I've attached the "udon behaviour" component? Or do I have to input it manually somewhere?
God, I feel so dumb 😅
@floral dove You know what, I just realized that I don't have only a spawner to recreate in Udon, I also need to recreate a toggle that disabled/enabled some chairs, and I would feel very bad asking someone else to waste so much time in helping me. And then again, if I had a problem with it I wouldn't be able to fix it or even try, because I don't get how it works. That can't be a solution.
Nevermind. The world I've made wasn't affected by any negative effect in the recent updates, it still works 100% perfectly, so I guess I'll just keep it that way until the old trigger system is definitely gone lol.
Sorry for clogging the chat with the wall of text ^^
floral dove
@scarlet lake I understand. Udon is in Alpha and a little better suited for people that know something about scripting and the way Unity and C# work at the moment. We'll have some features and tutorials coming that will be friendlier to complete beginners. We all start somewhere!
scarlet lake
Yeah, VRChat already made me discover a passion for 3D modelling, which I used to make avatar and worlds. The trigger system was way out of my league, but I could do basic stuff like toggles. Udon feels so great and powerful, and honestly, I'm very exited about what it can do and what others will do but... now I feel a little powerless lol. My friend had big ideas for this gathering world I've made for him, and now I have to be the bearer of bad news lol.
I guess I'll advise him to hire a programmer or something lol
If you want to hear the opinion of a random idiot with no programming experience: don't dumb down the system for us. It will only make it more limiting. Just make it more easy to basic stuff for us. Add some "pre built" script like a spawner or a toggle with a simple readme and we'll be fine. ^^
floral dove
Thanks for the feedback! We'll definitely add more examples and premade stuff.
Also @scarlet lake you can still use triggers for your new world, there's no "end date" right now for SDK2 (the old triggers, etc system) going away.

green plinth
Could anyone tell me why the heck when i use the identical script to others and likewise when i make a fully working script, that when i test it, IT DOES NOT WORK!!!!
I am so fed up with this BS it was the same issue with the old system, things that should work DOES NOT!
Seems i found the issue, apparently when a null object occurs it refuses to compile (ever). Even if it is no longer null...
Anyhow for some reason the compiler refuses to compile and does not tell you it failed...
worn hare
how do you fix this issue?
green plinth
Beats me, it should not happen in the first place.
And if i rename public variables they do not change name for same reason.
both the auto and manual compiler refuses to function
worn hare
i also dont understand how a udon script works perfectly fine in playmode but refues to workon the test client and published world.
civic vale
What says that an action is triggering locally or globally =o?
like getting local player position then setting an object to that position
what says that the object is setting its position for everyone or just you
green plinth
Hi @civic vale Udon giving you a headache as well?
worn hare
likewise.
green plinth
Im just trying to get anything working period, just like in the old system the updates are not being saved properly, so regardless what i do it's hopeless.
civic vale
I'm just curious if the object will attach to each person that joins locally or will it attach to the first person that comes
or do I need to set up a whole different thing for this event happening per person 🤨
green plinth
Btw you might wana set it for when player joins.
Might make it a whole lot simpler for you @civic vale , as player joined gives a player object for you to add that to
But yea i am trying to make this advanced toggle work. but it refuses to budge. https://ask.vrchat.com/t/phaxenors-examples/273/4
worn hare
im just an actual dum dum, got my issue solved.
floral dove
@green plinth do the examples in Assets/Udon/Examples work for you?
green plinth
Seems i found the issue, for some reason the compiler hates when i use multiple events to trigger with so it fails to compile....
Odd thing is that i have used complex 3 event triggering before and no issues...
floral dove
Ok, if you have any specific issues you can post them here for someone to try and help!
green plinth
Anyhow it seems the only easy way to verify that the compiler updated the code is to have a public variable that you change name on and then confirm the compiler updates it in the inspector....
floral dove
@green plinth you can take a look at compiled code and see that it updates as well.
green plinth
Yes @floral dove but with larger code it can be a real pain to check if the code altered at all.
floral dove
I've gotten in the habit of pressing reload and then compile, usually triggers a compile for me unless I have an error.
green plinth
Btw how you zoom the Graph mode?
floral dove
@green plinth no zoom yet.
green plinth
Anyhow @floral dove this is just ridiculous. I been trying to replicate the advanced version this guy made. https://ask.vrchat.com/t/phaxenors-examples/273 but it refuses to even compile. 😢
Fact is that i seemed to be having the same issue with the old system, when i changed triggers and tested it, the changes did not set in at all.
storm copper
how i can make an void buttononclick() ? so thats activate a method in my main program
im using udonsharp
flint urchin
@green plinth what's the error you get when trying to compile it?
green plinth
thats the most annoying thing about it @flint urchin it does not give errors it just leaves the old script and does not update it.
flint urchin
Then it could be the bug with using Get Variable on multiple nodes
floral dove
@flint urchin that's fixed in the latest SDK!
green plinth
there a new one?
green plinth
@flint urchin i tried split the get variable into 2 seperate ones and no change.
maybe i have to dosaem for object [] get?
Ok @flint urchin i simplified the code to the point where it no longer does it's task but should still compile, yet no change...
flint urchin
Give me a min
green plinth
Anyhow, i am gonna update the SDK and hope, but is it the same procedure as for the old non-udon?
turbid vortex
how do i make sure the action done in the udon script is user local not effecting everyone ?
flint urchin
Everything is local by default
green plinth
And that leads me to my question @flint urchin how you make the changes global?
flint urchin
Make variables synced and send networked events (not fully working)
@green plinth yeah, in the new SDK it's working
halcyon rock
new to udon, i think i figure out the graphs part but idk how to apply it to objects or im just dumb
green plinth
@halcyon rock use a global variable to fetch a object to alter.
halcyon rock
not using an object to alter, just use it to interact to make other objects disappear and other reappear
green plinth
Basically a mirror button, the interact will only function on the object it's used on, for the script to know what object you wana alter you need a global variable in order to tell it what object you talking about.
floral dove
@halcyon rock check out the examples in 'Assets/Udon/Examples'
halcyon rock
time for some testing
green plinth
@floral dove seems the compiler still freaks out if you use 2 events on same connection
Also @floral dove seems the code as @flint urchin said works fine in the new SDK. So ty.
Also i have a second issue, apparently when i have a regular pickup object, for some reason it is local, meaning if someone moves it you do not see it happen, what is the new system for it?
flint urchin
Check the Synchronize Position
green plinth
so you just use a empty udon behaviour script then @flint urchin instead of the old system?
flint urchin
Yeah, but the Udon Behaviour will need a Udon asset assigned to it. Can just be empty if you're not doing anything in it
halcyon rock
my brain is fried
green plinth
so simply a None Source will do @flint urchin ?
flint urchin
No, you need a empty udon graph
green plinth
Dang how annoying....
flint urchin
¯_(ツ)_/¯
halcyon rock
wheres the other material where its gonna swap to in the example on the in interact?
green plinth
@halcyon rock in the script or in the files? Because if it files it is your choise.
halcyon rock
theres nothing to swap to in the example?
green plinth
if it the one im thinking of there is 2-3 of them, just find the source in the inspector and click on it and the file gets marked.
halcyon rock
can i swap a game object in the hierarchy?
green plinth
any changes in the hierarchy are tracked so any refferences are altered to the new position.
but yes if you drag and drop a opbject from hierarchy into the inspector if it's valid it adds it in
halcyon rock
like if i made a game object for the sake of turning multiple things off or on
and its not mesh
green plinth
well if you have a root with branches and the root is turned of the brances turn off to
halcyon rock
yea
green plinth
same as in the old system
halcyon rock
whats the udon code thing for it?
green plinth
game object set active
halcyon rock
whats the difference between Game object and Game object[]?
flint urchin
[] is array (multiple)
green plinth
[] is a "array" meaning it holds multiple objects.
to use it you must call the object according to it's index value (starting at 0 for the first one)
halcyon rock
so i use array if i do the list of objects in a hierarchy?
green plinth
yup, and you read it like a book with numbered pages
halcyon rock
thats cool
green plinth
and practical to, currently working on a random teleporter on that principle
floral dove
Btw @green plinth I know this was a little while back but there's an Udon Program called 'empty' in the Examples folder for using as a nice blank graph. The examples Readme explains this 😜
green plinth
no problem i already made my own @floral dove thanks tho, i should look a bit more into it.
One thing i need to ask tho @floral dove regarding teleport player on interact, i noticed that the interact event does not have data attached to it (like who interacted with it), is "networking get local player" supposed to be a substitute for that?
green plinth
I believe Tupper made a video about that.
storm copper
do you have it?
green plinth
try 4
storm copper
nope
thats not it
im talking about methods not variables
he is importing variables
green plinth
well it does a simular thing, also is there methods in Udon? I am a bit unsure now
green plinth
not sure if this helps https://ask.vrchat.com/t/vrc-triggers-udon/196/3

@storm copper I'd recommend you join the U# discord for help with C# scripts

oak jungle
Can anyone help me with Udon for muting and unmuting an audio effect?
green plinth
is not that like 0 volume? or is there a actual mute?
oak jungle
I have buttons I want to toggle the audio of a fireplace and water fountain
How do I target a specific audio source?
green plinth
does a audio source have a volume you can target? Because are not volume handeled by what plays it?
oak jungle
Eh, most likely but I am having trouble targeting the audio source
green plinth
in what way what for?
halcyon rock
need a graph to toggle multiple objects on and off
green plinth
maybe try get/set mute @oak jungle
oak jungle
The main trouble I am having is targeting the specific AudioSource, public variable isn't working
green plinth
I feel like trying this for the heck of it give me a while (got to find a audio clip to test with lol).
oak jungle
Okay, if you have an update for me, please tag me!
halcyon rock
i wanna make it so that an object stays toggleable when i push a button but set an object to inactive at the same time
green plinth
PhaxeNor made a good toggle button example
halcyon rock
for multiple object function?
green plinth
if you wan toggle off multiple at same time yes
halcyon rock
multiple off and multiple on
wait
udon is different
if set of objects is on already when i push a different button, i want that same set off and toggle the next set
basically
green plinth
basically if it's off then on and on then off, not all off and not all on
halcyon rock
wha
green plinth
if mirror A is on and B is off you click one button and they effectively swap their state on/of
halcyon rock
if set 1 is on from a button that toggles set 1 on/off and when i push button 2 it toggles set 1 off and toggles 2nd set on/off
halcyon rock
dont wanna leave sets on like pictures and stuff hehe
green plinth
Simply use public variables just like in the toggle example but modify it so a specific portion is always turned off by the same action
halcyon rock
hmm
green plinth
use the advanced toggle https://ask.vrchat.com/t/phaxenors-examples/273/5 but put a public variable that says that the indexes up tot hat number are always off
halcyon rock
wonder why a game object have a value checkmark but the sets of game objects doesnt have checkmarks
halcyon rock
indexes?
green plinth
you know how a "for" works?
halcyon rock
just started to mess with udon today xd
green plinth
you know object oriented coding?
halcyon rock
uhh
green plinth
the variables with [] are arrays, they contain multiple objects like a book with pages, a "for" function is often used to browse thru each page, they start at 0 step 1 at a time and the index is a refference to what "page" you on.
halcyon rock
so the position of an object in the book is important
green plinth
if you got a array with 10 objects, you can tell the code that anything with index 5 or less is to be always turned off.
halcyon rock
how about all of a list?
green plinth
yes they got their corresponding index
hum
not sure what you reffering to, sometimes a array is mentioned as a list.
