I do have this problem. For now I just double check on the website to copy-paste / proofread patron names that have punctuation. Meanwhile working on an automated char replacement table for all these strange bois

Google survey to get patrons vrc names when signing up. Then an editor script to load them into the world and format the UI. Half of it is still done with direct messages though because I just like to say hello and thanks + other circumstances. It's not that bad. Sorry everyone for clogging up the recently updated row, that's why I mass upload on Monday mornings

Ah yea I usually try to say hello and thanks too but then direct them to my discord bot to link their discord with VRChat, thankfully I do not have to upload the world cause I figured a way to get tons of data into VRChat from outside so I just do that.
Do you upload only recent/most played worlds with new patreons or all of them ? I am guessing just recent/most played otherwise it would really be pain updating it weekly with the amount of worlds you have. At least for me it would with my crappy connection to VRChat servers :/

timber lion

That's nice but I haven't found a way to list everyone's name via web that works with allow untrusted urls off

Most recent worlds within reason. Will start doing flair enabled ones only probably

And sadly it also means that there needs to be at least 1 PC user in the history of the instance to download the list and send it to Quest
I have example here https://github.com/Miner28/AvatarImageReader (Slightly outdated just for concept)

timber lion
#

Oh so quest pedestals can't hold as much

#

Is that just a resolution thing? I didnt know there was a difference, never messed with pedestals

stark adder
#

Its to save VRAM probably.. That is my guess

stark adder
#

I mean it is understandable I guess ? If Quest would download 200 1600x900 images in some avatar worlds they'd probably die real hard

timber lion
#

Well this seems cool for PC at least, oh well

#

Thanks for letting me know

stark adder
#

It works for Quest too but.. Yea has some issues as I said awhoknows Not sure what's the percentage of PC/Quest in your worlds. If there is at least 1 PC in each world's history. Also what I do is a BACKUP system basically it is backup patreon list which I update once a month which is used by Quest/PC if they are unable to download it.

I know im probably missing something but I cannot seem to find the option to create a Udon# script in my project, only C#, this is with the latest sdk3 for worlds and unity 2018.4.20f1

Well...have you imported UdonSharp? 😅

scarlet lake
#

there is a separate package?? omllll

UdonSharp is a C# to Udon compiler made by the community Member Merlin. It is not an official product of VRChat, so it is not included in the SDK. You need to download and import it yourself :P

How to read right controller joystick position

vocal copper
#

Is it permitted for world creators to add malicious / game breaking logic to their world targeting other users? For example using UDON to target users based on their username and to not render anything for them. That way when the users join their world then these users will continuously fall and will have to restart the game?

cold raft
#

dunno feel free to read the ToS yourself

vocal copper
#

Well there is Section 12 Prohibited conduct

#

"f. upload to the Platform any software code, routine, or instructions that interfere with, or otherwise attempt to impair, the operation of the Platform, any user’s enjoyment of the Platform, or any ..."

#

My point is what would happen if world creators use their public worlds to just introduce game breaking behaviour?

stark adder
#

But I doubt that if you use it to just deal with very few number of people that are crashing other people in your world or using racial slurs or similar stuff anyone will do anything about it. As of now there is absolutely NO way to deal with those people and VRChat support just ignores them.. Cause there's too many of those 🙂

fiery yoke
vocal copper
#

The thing is that I wasn't going to that world anyway. But having to restart my game I think is a stretch. Do I have to double check what world is a friend trying to invite me from every single time? My point is that they don't only make it inaccessible they lock you in continously falling loop. On purpose. There shouldn't be such a public world ever. That is abusing a vetting process where their world got made public and after the fact they introduced a malicious under the radar behaviour

scarlet lake

I guess if you find one like that, report it. World like that shouldn't make it out of labs.

fiery yoke
# vocal copper The thing is that I wasn't going to that world anyway. But having to restart my ...

Well thats a problem in how VRChats community labs system works, because you only need to get it through the process once, and you can then make any modifications, without having to go through it again. Which is reasonable for people that make frequent updates, but bad for people that abuse that fact. Ultimately you can always send a ticket/email to moderation@vrchat.com or use their new fancy ticket system (not sure).
Its not strictly forbidden afaik, but its definitely not "allowed" either. There is always a golden rule on the internet: Dont be a dick.

That is an almost 3 years old video of 6 and a half minutes long video in another language. Buy the fact that it's a 3 years old I mean that even if the symptoms are similar, the cause and details of the behaviour might have changed. Devs really really like details because they might be hint towards the root of the problem. Further I have no idea what the fav limit was back in 2018. Probably you would be better off crating a fresh video specifying exactly what we are looking at. What we should see and what we see instead. Then probably should head to https://vrchat.canny.io/bug-reports and raise it as a new bug.

if you really want to dig into it, it should be possible to modify that prefab to not use an input field

yes, but it would likely not work. You'll have to replace it with something else

actually it was just to facilitate the input, but I can rewrite it to not need input fields, thanks for the quick and expert advice 🙂

tribal meadow

OK I screwed this up royally, and edited the wrong script...attempted to rename/reimport and I have two scripts in the assets folder with the same Serialized Udon Program Asset ID....how do I assign one of them a different ID number?

tribal meadow
#

Removed both versions of the script, tried to re-import it from the package, the modified one still comes back...I even deleted the files via file manager....I guess the only way is to manually put the script back the way it was?

scarlet lake
#

So I was trying to do something to an object like move it up and down with a slider. And when I searched about it, everything wanted me to write a script in c# and then put some udon behavious. Do you need to use c# scripts along with udon, or can you do anything you want with just the udon graph system?

void ridge
#

If you then delete the original asset, you effectively have the same asset with a different ID

tribal meadow

It's not doing that for some reason for me. I've even re-imported it from the original git hub download, and it' keeps coming back. This must be a Unity bug.

Were synced animator states going to be a thing? I recall a sync animations checkbox in an earlier SDK

fiery yoke

Supposedly. They were "Coming Soon" for a while. Until even VRChat had to admit that that "soon" was a bit of a stretch.

You can technically make your own scripts to sync animation state, but its...well inconvenient

I might be able to figure it out if pointed in the right direction

Also are UdonBehavior arrays not allowed?

How do you get a player's current view position (for raycasting)

cunning mist
# pallid mango How do you get a player's current view position (for raycasting)

OnPickupUseDown only ever fires for the person who is locally pressing that pickup, so you're safe just accessing the local player for that one. To access their head for raycasting, use GetTrackingData from that player to get position and rotation. To get the actual direction the player is looking in for the Raycast, just multiply their head's rotation by Vector3.Forward.

floral dove
# cunning mist With getOwner being a check on the network data, would currentPlayer *technicall...

as far as I can tell, currentPlayer checks the sync component on the Pickup and returns its owner. There's a separate path for non-synced Pickups that get the VRCPlayerApi component on the VRCHandGrasper object currently holding the pickup. In either case, the method incurs a single GetComponent call. I suppose you could make a non-synced pickup and then want to use the .currentPlayer property, so that might be the 'most correct' way since it would work in either case.

#

However, you're making fewer calls if you check the owner of the Pickup directly instead of calling on its currentPlayer, so for a synced pickup, that may be a more performant route.

So I'm working with this graph to check whether or not a bool value is true or false, and when the button is pressed the values are flipped so that users can deafen their voices when the button is pushed, and undeafen when it's pushed again. Anyone know what could be wrong with this graph?

floral dove
#

btw, you've over-complicated your logic quite a bit. Since you're already branchin on 'OnOrOff', you don't need to check the value of that variable and flip it in order to set it to the new value. In the 'Set OnOrOff' nodes after your branch, you can just use the built-in checkbox to set whether the new value should be true or false. That will be a good start towards making your graph a bit more straightforward and readable.

I want to use Udon to rotate an object when someone picks it up and rotate it back when they drop it. I played around with the nodes but do not see an obvious way to rotate something. Does Udon support this?

@tidal night Did not think of trying a generic Transform. This looks very promising. Thanks.

I just expect that when I hit the button, the player who pushes it will have their voices muted to a lower radius, and when pushed again, it will reset to the default VRC values. It does nothing, currently. I'm actually trying your below right now, loading in currently.

# floral dove ah right - you can use bool const nodes to make it clearer then:

Didn't seem to change anything, I might have to drill down a little with some of the stuff for players. See what's going on is I currently have a Trigger box that collects the player ID of the person who steps into the trigger box, setting their voice low. However, there is a huge inconsistancy of how often this works so I wanted to try and make a button that gets the player ID and then changes it manually that way, instead of relying on inconsistant trigger box events. Would the problem lie in the instance I'm using for the "Set VoiceDistanceNear" area, with "Get LocalPlayer"?

floral dove
#

Yes, that's likely. Take a look at the docs - this changes how you hear other player's voices - so it looks like you're changing how the player hears their own voice, which won't do anything.
https://docs.vrchat.com/docs/player-audio

rough geyser
#

That would make a little more sense then...

#

Let me do some digging here.

#

I need to find out how to get the playerID of the person who hits the button, is the primary thing.

floral dove

sounds good. The UdonExampleScene used to have an example of this but it was dropped in the UnU merge. You may be able to grab the example from an older VRCSDK package if you have one.

I am brand new to udon and need some help

#

I have 2 buttons, one for an optimized mirror, and one for a high quality mirror

#

I want the lq button to activate the lq mirror and the hq button to activate the hq mirror. however, if the lq mirror is active and the hq button is pushed, i want it to deactivate the lq mirror. does anyone have a good way of doing this?

floral dove
#

Give each button a reference to both mirrors, have the LQ button turn LQ mirror on and HQ mirror off. Have HQ button turn HQ mirror on and LQ mirror off.

feral merlin
#

This is what I have now

floral dove
#

Ok, instead of always flipping the state of setActive, have this program always do SetActive(true) for the HQ mirror and SetActive(false) for the LQ mirror.

feral merlin
#

But I DO want the button to disable the mirror if it is active

#

I.e. the HQ button is pressed while the HQ mirror is active, it disables the HQ mirror

floral dove
#

Ok

#

So then have this graph SetActive on the LQ mirror to the opposite of the value you're using for the HQ mirror.

feral merlin
#

But then wouldn't the LQ mirror turn on whenever you want to turn off the HQ mirror?

fiery yoke
#

On the HQ Button: Always turn off LQ, Toggle HQ (like youre doing it already)
Then vice versa on the LQ button

#

That will ensure that there is always just one mirror on at a time at maximum, and clicking the button for the mirror that is already on, will turn it off.

feral merlin
#

Yeah that's what I was thinking, I just don't know how to implement that

#

I know virtually nothing about Udon and just followed a youtube tutorial to even set up that button

fiery yoke
#

Well you basically just need a another SetActive node with a const boolean that is false.
Then you feed in the LQ to that SetActive node

feral merlin
#

But the interact event can only go to one thing right?

fiery yoke
#

You can either use a block, or use the arrow that comes out of the other SetActive node (which is what I would recommend)

feral merlin
#

Yeah when I move the arrow to another set active it gets rid of the first one

fiery yoke
#

There is a white arrow that points to the right, at the right side of the SetActive node. Essentially the one on the left is an "Input" and the one on the right is an "Output"

feral merlin
#

Right

fiery yoke
#

It goes through the input, then does whatever that node tells it to do. And then continues through the output.

floral dove
#

BTW you can check out the UdonExampleScene and docs for lots of examples of how the different nodes work: https://docs.vrchat.com/docs/udon-example-scene

Udon Video Player

#

had a question about using it on lights?

#

bc it comes with a video render for lights.asset but idk how to use it

Hi does any body know how to set up a simple

on player local - if player enters collision -Audio plays.

#

audio plays locally

#

You can simplify that a little bit by using VRCPlayerApi.get_isLocal

pallid mango
#

I do have a habit of using extra nodes

torn pendant
#

thank you

torn pendant
pallid mango
#

I just hit space bar and type branch. Make sure the cursor isn't hovering over a node or the search feature is filtered to methods of what you were pointing at.

#

Branch is Udon’s 'If'. I've never seen it called Branch before Udon

torn pendant
#

ohhh found thank you!

floral dove
fiery yoke
#

Technically an "if" usually causes a branching in the flow of execution. The CPU then has multiple "paths" to go down. Thats why its called a Branch.

pallid mango
#

I think it's a more suitable name. I just have years of thinking of it as an if

#

This is my first time working with node / flow visualization. Finding it hard to keep things organized once it gets big. Are there best practices for when you get a really big graph?

#

It seems to get unmaintainable to me

fiery yoke
#

Well ideally Sub-graphs

#

but those have not been addressed at all since forever, so no idea if thats even still on the "SoonTM-List"

pallid mango
#

I'm guessing that's like make group in blender shader nodes?

#

Turns it into a black box?

fiery yoke
#

Well not quite, but yeah. Essentially its what allows whats called "Abstraction".
When you build a machine that takes some input and produces some output, then you dont need to know what the machine looks like on the inside or how it works, when you want to use it in a bigger machine. So you hide the implementation and only the interface remains.

#

Are there downsides to splitting things into multiple udonbehavoirs? (1 behavior with 2 events vs 2 behaviors with 1 event)

fiery yoke
#

Well performance. But unless you notice performance being bad you should never really optimize for it, unless you can definitely predict that performance is going to be an issue with your implementation.
Ideally you should always do what makes sense to you.

pallid mango
#

And are custom events the main way to 'send information' to other behavoirs? I've been relying heavily on it, not sure if there is meant to be a different way

fiery yoke
pallid mango
#

Ok. Feeling a little more confident then that I'm not doing everything wrong

Hello,

Is there a guide located anywhere or a script or setting to add sound boost pads in SDK3 worlds? The areas where you stand and it boosts your mic volume and range, used for DJ like events?

I hope I'm not interrupting anything, but I'm working on a world with slime enemies and I was able to program them well enough to the point where they will die after being attacked with swords. But instead of just having them do the die animation and just sitting there I'd like them to despawn if that makes sense. I don't want a bunch of slime corpses all over my map so is there an inverse to this spawning that would assumedly get rid of objects after a certain trigger. Preferably it would be for udon graph as that's already what I used to program all the health and animation for the enemy.

hearty isle
#

Thank you

floral dove
sharp vigil
#

What if I didn't need it to sync. The instantiate handles spawning just fine for spawning local items, and thats all I intend it to, but what about locally getting rid of them too. I was just wondering if there is a counterpart to the instantiate function that would do the inverse.

cunning mist
#

That would be Destroy
Please don't Instantiate and Destroy 😦

#

These are not what we would call "efficient" or "performant" things for you to do.

sharp vigil
#

Hmm if thats the case I guess Iook for workarounds. I just figured instantiating and destroying the enemy one by one would be more performant than having a ton of prespawned slimes. But now that I think about it I could probably set them to be inactive once they die and while there meshes aren't rendered have them move back to a spawning area to effectively "spawn" which would just be setting them active again

floral dove
cunning mist
#

Object pools would be phenomenal for this, though if you're going for single player then VRC's Object Pools are networked only, so you'd have to make your' own.

sharp vigil

Ok I think I got ideas on where to go from here thanks you two. Oh and I've been using tutorials on youtube from you two to learn udon and U#, Im already 2nd week in and I've been learning a ton, super helpful, thanks again. 😄

I really don't understand why, but I can't get a simple mirror toggle to work normally. I thought I had gotten it to work, bu using a scrip that came with udon sharp, but that was a global toggle, so not what I want, since mirrors should really be local. When I tried making the toggle from scratch following tutorials, it didn't work. Basically when i went to test it, it just wouldn't show my button as a thing I could interact with, even tho I had set up everything exactly the same way as in the tutorials (I had a collider, all the nodes were correctly connected, ect) and when I tried the script that came with the sdk3 (ToogleGameObject) it wouldn't work either (Wouldn't make the button intractable). I have no idea what I'm doing wrong or how to fix this.

floral dove
#

To make an object Interactable, it just needs a collider on its GameObject and an Interact event in its program.

disappointed to discover lightmapping is not yet exposed in Udon :C

wanton oxide

what do you need it for?

cause so far i've found workarounds for all my lightmapping needs, maybe one of them is useful to you :P

Is the player names exposed in udon? For example using name plates tracking data

wanton oxide
#

yes

#

vrcplayerapi.displayname

sorry kinda typo, i mean player name plates*

could do the head bone and use some contrainer magic and some other tracking magic

Currently no way to do that. You may have to link caller game object to that udon behavior so it can read the parameter from the caller object.

i have current question:
i'm trying to make a visualizer for the audio source that hat 3D blending and i'm using GetSpectrumData to get the results but problem is it includes falloff so the results get "quieter" as a get further from the source (seems to be a unity behaviour)
i tried to make a dummy audio source that would have 2D blending and would output to nothing, that is having it output to audio mixer i've created but what i see is that vrchat takes control over the output variable because i end up hearing both 3D and 2D sound (failed workaround)
is there any other way to get it working?

Under what conditions would you make a udon variable that isn't public? Just curious about the use-cases

Is it even possible to assign scene content to variables if they aren't public?

Will Udon make shaders more compatible for quest?

chilly crater

If I want to set a Vector3 array of saved positions that won't change for the life of the world instance, should I do an IsMaster check when I set it?

#

I was going to UdonSync it so newjoiners will get those values too.

#

Or would it be more network performant if I make each object a child of a unique parent and set their localposition to 0,0,0 when reset is called?

junior hornet
#

hey everybody, I just started to learn udon. Is there anyway to communicate between udon scripts? e.g. in Unity, I could have monobehavior A & B. Monobehavior A could call into public functions of B, along with arguments, as long as it had a reference to the gameobject. From what I can tell, Udon seems to provide no real way of doing this. There is the SendCustomEvent, but it has no way to pass arguments.

wanton oxide
#

are you using udonsharp?

#

if yes, you can do exactly what you can do with monobehaviours

#

including parameters

#

if no, use udonbehaviour.setprogramvariable

#

you'll be able to set public variables on the target udon behaviour (no function parameters tho)

junior hornet
#

I just started using udonsharp, how would you be able to do this? Doesn't the udonbehavior hides the undonsrharp underneath?

#

I wouldn't be able to do something like UdonBehavior.MyMethod()

wanton oxide
#

udonsharp has some magic under the hood compiler stuff

#

that makes it so you can do just that

oh

thank you

System.Exception: 'UdonBehaviour' does not contain a definition for 'FooBar'

ok, I see, you need to have established references to your UdonSharpBehaviors.

wdym?

if i touch a player, it triggers an event on the other player's end

and globally

i dont think theres a tutorial for that. itd be a bit of complex setup to go over

damn

wish that kind of system were built in

It's ocnfirmed to one day

thatd be a weird system

Not that specific system, per say

quaint crystal
#

is there at least a combat tutorial

fading cipher
#

But player trackers or player "variable holders" are confirmed to be supported natively in the SDK one day

#

And you could totally use that system to write a player-based trigger system

dapper lion

It's not impossible to write either- we use player trackers for everything right now...

ye player tracking is fun

is there a tutorial for one of those?

i also made a "no more bs" toggle system that could be used for global events... but pooling trackers for clients so it does the triggering would be the part i wouldnt know how to do

Have been banging my head for hours cause I cant get a simple button to work in this project. I do not know why but when I go into runtime the buttons clear out their stuff and come back after going out. I know the Udon portion itself is working tho since using CyanEmu I can play it. Just dunno why my buttons are all screwed up or idk

grand temple
#

have you tried ingame?

#

cyanemu isn't 100% accurate

idle flare
#

yea its the same thing and I dont know why my buttons are shoving out stuff during runtime

grand temple
#

Could you share any details about how it's set up?

idle flare
#

as simple as it needs to be I think but ye, can see in that gif how when I click play it says Ive got nothing attached to button

grand temple
#

the button isn't set up correctly. you currently have it set to "udongraphprogramasset.name" which is not something you can modify. You probably want sendcustomevent instead

idle flare
#

only options I get

chilly crater
#

The script has to be on an object, right?

grand temple
#

for some reason the target is locked on the udongraphprogramasset, not sure how that happened but try replacing the thing on the left

#

ohh I think you dragged it from the assets tab. That's not what you want. Instead you should drag the gameobject that the script is on

idle flare
#

ahh, havn't viewed this project in ages and updated my sdk and it put it as that :shrug: Gonna try that.

I love UI buttons. You can have ALL of the button events on one script.

zenith quarry
#

If I've got some complex motion (eg for a flight simulation) that I have expressed in pure math, is there an Udon node where I can simply write out the equations? Or do I have to break the whole lot down into a huge network of those Single nodes (multiplicator, subtraction, etc) and wire them together?

prime fossil
#

can udon interact with the vrchat webapi?

Not that I know of

how powerful are web requests in udon

can i get & post to external uurls? i saw a google analytics plugin but didnt look at that code yet

#

I doono I never tried, but I afaik the functionality is limited to protect the users

zenith quarry
#

Can you mix udonSharp with the nodegraph (the U# in just one node), or is it all one or the other?

#

The only other node-coding system I know is NodeRed, which is Javascript based, so you can always put Javascript in a node if the node graph would otherwise be too complicated.

Nodes work for some things, and code works for others, so you kind of need a mixture, IMO

cold raft
#

udonSharp nodes are entire udon behaviours, so they come in place a a graph, but you can have multiple udon behaviours in your world some can be graph other can be udon sharp

zenith quarry
#

Can they share variables and call out to one another, or do I have to pass things through on the state of a GameObject.?

In particular, with flight, you've got a whole set of velocities and orientations that need to be numerically integrated, but all that comes out of it is a single velocity vector per frame, so it's a very self-contained piece of mathematics that's not doing anything awkward, such as collisions.

grand temple
#

you can interact between udonbehaviours with sendcustomevent and setprogramvariable. Once it's been compiled there is technically zero difference between an udonbehaviour that was made by U# or graph

#

however, U# does some stuff behind the scenes that allows you to call an event with parameters, which isn't something that udon natively supports. But U# makes it happen by just compiling it down to setprogramvariables and then a sendcustomevent, and you don't have to worry about how it happens. But it means that the graph can't really interact with those special events with parameters, it is exclusive to U#

zenith quarry
#

Hah, there's hope. I got the SpinningCube Usharp example to spin round a different axis. (It seemed to kick up the Microsoft Visual Studio as the editor whether I wanted it or not). This establishes for me that it's technically straightforward. (much more so than I anticipated).

Now I've got to find someone to hire to help knock something up because I haven't the time to teach myself everything from scratch. where's a good place to find people who can do vrchat worlds? freelancer? or is there a better place?

fiery yoke
grand temple
#

you can always ask questions here, plenty of people willing to help

#

though this channel is usually for more beginner questions. There's also merlin's Udonsharp discord which is where more technical questions are usually asked. Though it's really all the same people

zenith quarry
#

thanks for the offers. I'm not at that stage yet. (and haven't got any funds yet). But I'm just trying to evaluate different platforms for an application. I have to make sure I don't choose some framework where I'd hit a brick wall of some unsolvable problem further down the line, and that I am able to reasonably predict how much time everything is going to take.

This is why most commercial projects are so conservative in their choice of tech and stick only with what they know-- predictability of completion is more important than cost.

fiery yoke
#

Well VRChat is not necessarily a "good choice" then I would argue. VRChat focuses on letting users create worlds to explore and interact with, but its not a full VR GameDev platform with all kinds of features required to make a flawless and fully custom experience. (my own opinion)

grand temple
#

Udon's main limitation is performance, it's a couple magnitudes slower than regular C# in unity. The other is that you can't just import any library you want, you basically have to create everything from scratch. Then there's a couple tiny things like it only has arrays, not lists. It doesn't have raw web access. It can't read/write files on the user's PC, it can't persist between sessions, stuff like that. Depends how forthcoming you're willing to be with your idea but we could easily tell you if it's possible or not. Might be a hard no, might be a "if you put enough work into it, sure", might even be easy, idk

fiery yoke
#

Also additionally you cant customize the render pipeline, you can only partially customize the physics system, there is some limitations and problems you have to accept or deal with, like the interaction raycasts being blocked by every layer except MirrorReflection and other stuff

grand temple
#

the main advantages of developing in vrchat is that you can easily share and you don't have to deal with accounts, security, avatars, etc. Just focus on the world and that's all

fiery yoke
#

Yeah its ease of testing/deployment and network capabilities is certainly the main argument.

#

But then again its not really a GameDev platform, but just a social platform with limited UGC elements

grand temple
#

yeah that's a fair way of describing it. Though "limited" is maybe a stretch, it is pretty capable for what it is

fiery yoke
#

well yeah limited is relative

#

Compared to other UGC games/applications its definitely in the higher range. But compared to the basis of what youre building on (Unity) its very limited 😛

grand temple
#

yeah, pretty much. Had to remove a lot for the sake of sandboxing

wanton oxide
#

idk tbh, with some small things still missing (mainly, no way to talk to the outside world and no permanent data) i'd say vrc def gives me the most freedom of any of those platforms

#

tho one of those is already confirmed to be added which is great

autumn cargo
#

hey guys, it send the custom event even when it's false any guesses?

unknown.png
fiery yoke
#

IsValid is not meant to be used to check a boolean. Use a "Branch" node.

#

IsValid checks whether or not an object is valid at all. Booleans are always valid.

autumn cargo
#

ooh

#

i see, thank you

copper thicket
fiery yoke
#

Unfortunately thats a Unity thing. Unity can only read the audio data that is actually going to the mixer. And because VRChat overrides the Master Mixer with their own, you dont really have any control over that. So yeah. Too bad.

zenith quarry
# fiery yoke But then again its not really a GameDev platform, but just a social platform wit...

The trick is to know precisely what the limitations are, and the requirements of the application, so that when they fit you can do it and not be stuff with over-engineered solutions.

I think a lot of GameDev expands to fill the capability of the platform, so obviously if it's on a more capable platform it will look as though that application couldn't have been done on something simpler.

#

A less capable platform is a good thing because it avoids feature creep.

fiery yoke
#

Well first and foremost you should know the exact requirements of your project. Which is often hard to predict / figure out at the start.
ohh yeah you said that~ skipped over that

hushed gazelle
#

Just want to double-check, is this the right way to set up an audio source playing for everyone when someone joins a map?

unknown.png
#

Or can I just do it straight from OnPlayerJoined to the AudioSource?

fiery yoke
#

Yes. Everyone receives the OnPlayerJoined event. Another thing you should note is that you receive OnPlayerJoined events for players already in the instance when youre joining them. Which makes sense, because from youre perspective they are joining you. But that means that you have to be aware of that fact.

inner sorrel
#

I can't quite figure how to implement text advancement in my udon script. You can't have flow going into an interact event. Is there a way to have the flow pause until the next interaction?

hushed gazelle
#

Is there anything I can do to mitigate a stack of the audio source firing off repeatedly on-join in a busy room?

#

@inner sorrel, just make the next interact trigger a custom event. It's not like it'll fire any other way.

#

If you've got a set of strings to iterate through via the same button, make an array of strings, and increment it every time that button's hit.

inner sorrel
#

Thank you! I'll try that out.

grand temple
fiery yoke
grand temple

no

hushed gazelle
#

Do I need to do anything to mitigate a stack of local calls for all the existing players for the newly-joining player?

Oh yeah that would be if it was over-synced youre right. In this case its just n

grand temple

just remove the network event

# hushed gazelle Cool, Helper made it sound like there was an extra step to avoid it doing someth...

It has to do with 2 factors.
a) If you play an Audio Source that is already playing, it will not do anything. If you actually want to play sounds, while the audio source is already playing a sound you need AudioSource::playOneShot, which will instantiate AudioSources on the fly and remove them after they are done playing.
b) The audio source plays before you can really even notice it, because the OnPlayerJoined events happen really really early. Like basically while youre still joining the world.

pallid mango
hushed gazelle
#

Lol

I thought that might be the case, but better safe than sorry.

pallid mango

.PlayOneShot is also a good game recommendation

broken bear

For pc/quest synch I understand the hierarchy has to be exactly the same in both projects, but does that allow for making some objects inactive in one project? Or does it need to have the same active objects? I’ll have to strip components of a lot of objects and child objects if I can’t just disable the parent

yes, you can have different gameobject active state

that doesn't matter

#

if you're going to modify anything that comes with the SDK, just make sure to copy it over into your own folders so it doesn't get overwritten the next time you import the SDK

pallid mango
#

And I learned the hard way that you actually need to copy it and modify the duplicated one. Just moving it out of the SDK folder won’t stop it from getting replaced on update

#

Copied, but moved the original out and used it, kept the back up as original. Original file gets replaced no matter where it is.

I’m trying to change the color of an object based on the particle colliding with it, but I can’t find any way to tell the node which particle system it is colliding with. Does anyone happen to know how to plug in the particle system instance to the "Particle Get startColor" node, or a better direction I could go in?

particlecolor.png
pallid mango
#

This is sloppy but you could add all of the particle systems as public gameobject variables and fill them in and then run a for loop checking each one until it equals the gameobject reference coming out of the event node

#

The event node is outputting which system collided

west star
pallid mango
#

For loop with a array of gameobjects that contain particle systems.

floral dove
#

if so, you could just create a variable with a reference to that Particle System, or use GetComponent, but that will be less performant.

here's how to get the startColor of the particleSystem:

west star
#

That is very helpful. Thank you.

#

I have trouble navigating all the nodes

floral dove
#

Yeah, there's a lot of them. All the UnityEngine nodes follow the same path as they do in the Unity documentation, so if you look up how to do it in Unity, you can generally apply that knowledge to the graph.

inner sorrel
#

Do the "SendCustomEvent" nodes trigger events across all udon programs in the instance, or do I heavily misunderstand what that means?

floral dove
#

Runs the event 'eventName' on the target UdonBehaviour. If instance is left blank, it points to one of its own events.

inner sorrel
#

Thank you, I must've missed it while reading the documentation.

west star
floral dove
#

that's why I asked doesn't this event fire on the Gameobject with the Particle System in question?

#

you replied that it's firing - but the important part of the question is that the event would be firing on the Gameobject which has the ParticleSystem on it already, right?

west star

The particle system and the object to change color are on different objects. should they be under the same umbrella then?

You'll probably need to use a "SendCustomNetworkEvent" with the target of all. https://docs.vrchat.com/docs/udon-networking

Networking

The three main concepts used for networking in Udon are Variables, Events and Ownership.

I only recommend using Network Events for momentary effects. If you want to change something and have it stay that way for people that join your world later, you'll want to use a Synced Variable. Explanations are on the same page that Laughless linked above.

Hello hello !

I'm trying to fix a udon graph which do when click on a UI Button :

Synced Toggles | VRChat Udon Tutorial

So this took me longer than it should have.
Time to toggle objects again, but this time, for everyone! You'll see that syncing is a little bit more complicated than it was in SDK2, so to set everything up we have to tell every player to toggle that object, but also catch up anyone who joins in after the button was pressed!

i know how to sync object the old way using udon. how do you sync object now from a toggle system?

#

if you just want to sync the transform and rigidbody of the object, you can use the new VRC Object Sync component.

Trying to set up an avatar changer that changes your avatar when you walk over a box collider but it doesn't appear to work

#

I have it set up like this

#

Any idea how to fix it?

tribal meadow
#

OK, so going to attempt this again after giving it a break...(fresh start yay!) This is my previously working script for a synced set-material before the network update. What do I need to do to have this work again? Is it a simple fix or more involved?

floral dove
# feral merlin I have it set up like this

That looks good - is your collider a 'trigger' collider? Is your Pedestal variable set in the inspector? You can add a Debug.Log in to make sure the event is firing and your pedestal is set.

feral merlin
floral dove
#

Ok - collider and pedestal reference look good. I do notice that this is a prefab, though. I recommend you unpack it as prefabs and UdonBehaviours don't always play nice. Next, add a debug.log before or after your call to SetAvatarUse to see if this event is firing in the client.
You can learn more about debugging here: https://docs.vrchat.com/docs/debugging-udon-projects
Oh yeah - one more question - are you testing in the client or with a tool like CyanEmu?

feral merlin
#

Actually pressing build & test in the sdk menu

tribal meadow
#

sort of...basically, I have an object with a mesh renderer, and a bunch of different materials I want to set it to...There's quite a few of them, and a button for each different material. I'm not quite sure what I need to change. I'm looking at the U# script for both the synced toggle, and the set material script, and I'm almost wondering if it would be easier to modify it that way instead.

#

basically have it do set-material script, but have it so everybody sees it, not just the button pusher.

floral dove
tribal meadow
#

basically yes....it's for a stage background..... would this possibly work? I took the synced toggle, and replaced the Toggle with SetMaterial, or is this going about it the wrong way....

#

oops too long

floral dove
tribal meadow
#

ok, so this is the control panel, so what I want to happen, when one of the buttons is pressed the objects material switches. Currently it only works locally, but I need that to be global so everyone can see the change (including late joiners)

#

this is the local only graph

floral dove
#

Do all of these buttons change the material on a single Renderer?

tribal meadow
#

yes, correct.

floral dove
#

ok, cool. Let me whip something up...

tribal meadow
#

I appreciate the help

#

This will give me a better understanding moving forward, there's a few other ones I have that are simular but I've disabled them for now as they aren't as critical

dapper lion

tribal meadow
#

I'll take a look thanks

floral dove
tribal meadow
#

oh wow awesome

floral dove
#

@tribal meadow - so you can see in the video above two clients side-by-side. Each one can click on either of the buttons to change the material on the target object.

tribal meadow
#

yes that's exactly what I'm trying to do

floral dove
#

I split the logic up into two programs - a MaterialChangerButton, and a TargetRenderer.
The MaterialChangerButton graph looks like this:

unknown.png
#

This graph has a public 'target' GameObject and a public 'myIndex' int which you can set in the inspector.
The first group is just a way of automatically getting the UdonBehaviour component from the 'target' GameObject and logging a warning if it doesn't exist. You could drop it altogether if you instead made the 'targetUB' UdonBehaviour a public variable and also set it, this is just a pattern that I use a lot to automatically set things whenever possible.
The bottom group is where the action happens:
When a player Interacts with this object, we check that their Player object IsValid, then have them become the Owner of the object, change the 'materialIndex' variable on the targetUB to the index set in the inspector (just 0 for the first material, 1 for the second, etc), call RequestSerialization to have that object share its updated materialIndex variable with everyone else, and then call Refresh on it to make it change for this player, who is the owner.

#

Here's the graph for the TargetRenderer.
It has a public array of Materials that you can set in the inspector, a synced materialIndex int and a renderer.
It uses the same pattern as the other graph to get a reference to its own renderer on Start,
Then when the Refresh event is called, it simply checks its materialIndex variable, gets the target material from its Materials array, and sets that material on the Renderer.
When OnDeserialization is called, we simply call Refresh. This will happen for the non-owners of the object whenever materialIndex is changed, or when someone joins the World.

unknown.png
#

To be really safe, we should really check that materialIndex is not larger than the Length of our materials array when we go to get our material from the array.

tribal meadow
#

ok, so the first graph is the one your button would be set to, to tell it what background to switch to, and then it calls on this other script to actually do the changing (if I'm understanding correctly)

floral dove
#

here's what the safety check on the materialIndex looks like:

unknown.png
floral dove
tribal meadow
#

OK I thnk that kind of explains it better now...I really appreciate the help

#

I know of a few others trying to get this as well, so is it ok if I share these? (and literallys) as well?

floral dove
#

you're welcome! The whole OnDeserialization vs Owner logic flow thing is more complicated than I'd like. We actually have some changes coming that will make this sort of graph muuuuuch easier. Probably about 3 weeks away.

#

Yes, you're welcome to share this example scene.

tribal meadow
#

aah ok good to know...one other question, and probably been answered a million times, if I have an 'empty object' that contains a bunch of other objects, if I place the sync object on that, does everything in that empty object become synced, or do I still need to do it on each individual item?

floral dove
tribal meadow
#

ok gotcha, so if these need to be moved individually, they should each have their own, but if they are to move as a group, they can be set to the parent

floral dove
tribal meadow
#

ahaa ok.

#

goes to give this a try now

tribal meadow

Ends up I had a lot more wrong than just the script but it appears to be working now! Thanks Momo!

Hi guys, sorry I'm sure this has been asked a million times but, I'm using the player trigger enter/exit events in an attempt for the avatars hands to trigger things, but it only seems to trigger from the players capsule (which means actually walking over it?).

Back again with more Vive controls confusion (pretty much every time I have to touch them lol)

#

Trying to make something turn a color when the player presses their grab trigger, but I thought that input drop is the one called when they press the grab trigger right?

Yeah so pressing the grip button runs InputDrop. Does that mean releasing the grip button re-runs InputDrop with a value of false?

# 
public override void InputDrop(bool value, UdonInputEventArgs args)
{
  if (userIsVive)
  {
    if (value) fingerIndicatorMat.color = Color.red;
    else fingerIndicatorMat.color = Color.white;

#

If I set a gameobject's owner does that automatically propagate to everything inside it?

grand temple
#

ownership is per gameobject, not per component. So if you're asking if you have multiple udonbehaviours, yes they will all transfer

#

however if you're asking about children of that gameobject, then no those are separate and will not transfer

hushed gazelle
#

The latter, and cheers.

twilit epoch
#

How are you doing guys? So i want a video player that has some buttons on the side. Every button has a different URL. Also ownership should be transfered to whoever it is pushing. it kinda looks like this

#

The problem is, that i don't know how to do it.

#

And everyone in the room should be able to change urls etc. if its possible.

stark adder
#

Def possible

#

You want manually synced Url

#

Array with VRCUrls and the buttons on the side will represent a index of Url in the array

#

When you click one of the buttons you need to 1. Transfer ownership to person who pressed it 2. Set the sycned URL to the url of the button 3. RequestSerialization and then your system to load, play etc

If you want something to work for late joiners, you need to use a Synced Variable instead of a Network Event.

Networking

The three main concepts used for networking in Udon are Variables, Events and Ownership. Variables are containers for values - like a number, a set of colors or a 3D position.Events are things that happen at a moment in time.Ownership is the system that decides which user can update a variable, wh...

tawdry gust

@slim hound Is there a way to do that in the Unity editor? Or do I run multiple copies of the editor or something?

slim hound

You need multiple VRChat accounts

When you launch to test you login with one and on the next logout and into a different account

Ah, it will let me logout while maintaining its connection to the local test, I C.
That's pretty do-able.

I've been trying to transition from udon graphs to udon sharp, and I've found that a visual studio editor is not the best program for coding into. What does everyone suggest when coding with csharp

grand temple
#

Jetbrains rider is usually nicer in some cases, but it's just minor things. If you are having trouble with visual studio you'll probably have trouble with everything

#

Are you sure that autocomplete was hooked up? Maybe you just weren't making use of the features fully

sharp vigil

Nah it was just really laggy for a while for some reason, but I think I got it working better now

#

How do you get Auto-complete/Intellisense working in VS Code anyway? I already have a C# addon but it of course doesn't do anything when working with Udon Sharp

unborn hornet
#

If you open a script from within unity (generally double clicking on the CS file) having VSCode as your target editor, it should load it up correctly if you have the csharp extension installed.

so I used a video player prefab and found that it have a url length limit, is there a reason for it or is it just arbitrary?

I never ran into that limit

acoustic vale
#

something a bit crazy need opinions:

In Udon I can use the Video Player and an AudioSource to read the spectrum data. If I was to upload a youtube video that creates very specific spectrum data, could I use this to in theory program a world? Imagine you want the world to be in a specific setup, you upload a 10 second youtube video with specific audio. Load it into the video player then the spectrum data is read and the world is modified? 🤔

#

very very basic example, morse code

cold raft
#

Yes you can

#

Sending data through video streams has been done before, but I think most people encode it in the pixels rather than audio

grand temple
grand temple
tropic atlas
grand temple
#

you'd have to edit the prefab to also call requestserialization whenever the URL changes

#

but I would really just recommend getting an updated prefab. It's more than just that

this assumes you can read specific pixel data from the video player*

grand temple

yes, you can get the pixels from the texture

I'm trying to take the active state of objects in a game object array, and put them into an array of booleans.

By selectively deleting parts of the graph, I have concluded that the issue happens in the Boolean[].set

#

am I using the wrong component?

pallid mango
#

What behavior are you seeing?

#

This graph can error if the gameobject array is longer than the Boolean array

#

Since you are getting the length of the gemeobject array but iterating across the Boolean array

#

Be sure the Boolean array has the length you expect it to have

#

I don’t know if that is your error but it is a hole

frozen bobcat
#

does anyone else having issues with the AVPro video player repeating the first few seconds of the video link?

bleak echo
# pallid mango What behavior are you seeing?

The udon behavior just halts (on the Boolean[].set).
The boolean array started out as an empty variable. I guess I need to initialize it first (with the length of the game object array)? I'll look into that. I think you pointed me in the right direction.

bleak echo

It's private and synced

Does checking the value of a bool not work in LateUpdate?

pallid mango

Late update does not have any unique restrictions. It just happens after the frame is drawn new gameobject positions for the frame are updated instead of before

Useful for things like updating cameras so they aren’t 1 frame behind

#

Ok wow, that was my confusion. I had only been creating constants, so I just thought const was Udon's constructor.

frozen bobcat
#

okay sorry for all the question is there a proper way to sync to sliders togeter with out creating a update loop

#

for example if i move a slider on the left side of the room the one on the right side will update it's value and vice versa

fiery yoke
#

Sliders have an OnValueChanged event, where you can then do SendCustomEvent to an UdonBehaviour. You dont need an update loop for that at all.

frozen bobcat
#

no so i have one slider that updates world volume right

#

which is static meaning that it's fixed in the world by the screen and you have another volume slider that is not static it moves with the control panel that the player can pick up and i want them both to be able to adjust world volume but be in sync

fiery yoke
#

Yes. Both of them have to send an event to an UdonBehaviour when their value changes. Then the UdonBehaviour can get the current value of the slider and set the others slider value to that value.

frozen bobcat
#

so the onvalue change only fires when player changes the value

fiery yoke
#

Yes the OnValueChange event fires when the value changes. Who would have thought.

#

Ohh I see what you mean

frozen bobcat
#

yeah that's the loop i was talking about

fiery yoke
#

You mean a feedback loop

#

Well yeah then you need to add a little bit of logic to defend against that.

bleak echo
#

@floral dove @pallid mango Thank you, I'll try that now. That should be the final piece of the puzzle. The length is known when that component is called, so I guess const works, but it's good to know how to do it in case I have to deal with a dynamic array.

#

try logging col to see if your collision is even happening, first

also - it's not recommended to Destroy GameObjects in VRChat - Instantiation and Destruction aren't synced, so if you use this approach your world will look different for each player.

Actually no, the constructor and the constant create a NEW Boolean[].
and even creating a new Boolean[] and copying to the original Boolean[] variable, it still gives me an error.

#

I have tried everything I could think of

#

Test - initialize and set
Test 1 - set only
Test 2 - just initializing
(Test 3/unnamed group - ignore that, idk, I've messed with it a lot.)
Test 4- creating new boolean[] and copying to the original (I tried both with and without initialization)

All of the tests give me errors of this kind:
Object reference not set to an instance of an object

#

.
All I want to do is:
set my private synced boolean[] variable to a certain size so that I can then assign values to it.

If i have a script like this

#

I want all users to run Event A1 at the same time, but it doesn't work

grand temple
#

do you have any synced variables?

#

I don't think it will do serialization if you don't

placid kelp
#

If the synchronized variable doesn't change, is not serialize it?

#

ex) Player1 : 1 / Player2 : 1

grand temple
#

I'm not sure, it probably does

#

just to be clear.... this is way overcomplicating it and the only reason you'd do this is if you absolutely need the lowest latency possible. Are you sure you can't just send a network event and be done with it? It's higher latency (about half a second) but wayyy simpler

feral merlin
#

So got a quick question

#

I have avatar changers in my world that play a sound and change your avatar when stepped on

unknown.png
#

The only issue is that you can hear it whenever ANY player steps on one

#

How do I limit the sound effect to only play when the player steps on one?

grand temple
#

check if the playerapi is local and use a branch to stop if it's false

feral merlin
#

How would I go about that? I am a complete baby when it comes to udon

grand temple
#

add a new node, search for playerapi then search for islocal

#

plug the player that you get from onplayertriggerenter into that

#

and then plug the result of that into a branch node

feral merlin
grand temple
#

yes

feral merlin
#

Wait I'm confused now

#

I've got this

grand temple
#

yes, now you need a branch

feral merlin
#

Pardon my inexperience but what's that?

grand temple
#

it's a node, search for it

#

it would go right after the onplayertriggerenter, before doing anything else

feral merlin
#

Like this?

unknown.png
grand temple
#

yes, but don't forget to plug something into setavataruse

#

since you're already making sure that the player is local, it's safe to just use networking localplayer

feral merlin
#

Like this?

grand temple
#

yep

feral merlin
#

Sweet, I'll give it a spin now

#

Hmm... is there a delay between all this happening?

#

The avatar changing seems to take longer now

grand temple
#

it should be the exact same

feral merlin
#

I'm probably just imagining it then

grand temple
#

udon runs on the main thread so if it takes time to do something, it will completely freeze the game to do so

feral merlin
#

The sound does play at the same time and that happens in the graph after the avatar change so it would make sense that it's the same as before lol

#

Well, thank you much for helping out a newbie

vagrant schooner
#

Is it possible for udon to change the hitbox size?

grand temple
#

you can't change the real hitbox but depending on what you want there's plenty of other things you could do

#

like if you want to be able to crouch under things, you could dynamically scale the collider of the ceiling

#

or if you're trying to make a combat system with accurate hitboxes you could just make your own and ignore the built in ones

vagrant schooner
#

i was hoping to make it like, if you are small, then you can fit in between close objects

twilit trout
#

New to Udon, what do you use instead of coroutines to create events that happen over several frames?

grand temple
#

you can use sendcustomeventdelayed

twilit trout
#

And is it possible to use interpolation between floats?

#

i.e. lerp?

grand temple
twilit trout
#

Thanks!

#

Can I get a pointer on using custom events?

grand temple
#

what do you need to know?

twilit trout
#

Well, I can't find info on the concept on the documentation, so I'm wondering where to start

grand temple
#

it's pretty straightforward. You make a custom event, give it a name, then any of the "sendcustomevent" type nodes can make that event happen in various ways. You can do sendcustomevent to just do it locally and immediately, sendcustomeventdelayedseconds, sendcustomeventdelayedframes, and sendcustomnetworkevent which will make it happen for other players

twilit trout
#

oooh, thanks a lot, I get it now

#

Just testing stuff it's starting to make sense

placid kelp
#

If the variables are not synchronized, an error may occur on the next call

pallid mango
grand temple
#

just do sendcustomeventdelayedseconds and have it repeatedly call itself

scarlet lake
#

Stupid question but I thought I fixed this but the doors in my world do not sync globally. Someone told me toggle sync object position on the udon behavior but I do not see that. Can someone provide a screenshot of where this is?

dapper lion
scarlet lake
#

Is that it? Do I add it to the toggle button with the udon behavior, or the door with the animator?

dapper lion
#

the thing that needs its "rotations" and "position" synced

#

if you need per say a roation. you can use eular stuff. but that might take a bit to learn compared to the old object sync

pallid mango
frozen bobcat
#

okay so my world is only 22.41mb but quest users can't enter world does anyone have a fix for this

dapper lion
#

@frozen bobcat whats in it? anything serialized? audiolink?

placid kelp
#

ok changing the question, if I have 3 objects and when one of the players presses the button, I want to activate one of the inactive objects and move it in front of the player who pressed the button. What should I do?

frozen bobcat
#

i don't think so i already

#

the project it self does but not the world

floral dove

#

(probably) I found a 'gameobject' are no synced. so will be bypass in other ways

frozen bobcat
#

yeah i did it publish just fine

native rampart
#

is there any way to scroll up in the shift-`-3 log

#

if you load a URL in a video player, and then load the same URL again after that, does it stay cached or does it download the whole thing again?

fiery yoke

#

is there any way to pause a video?

fiery yoke
#

Yes. using videoplayer.Pause()...

native rampart
#

oh my gosh. I seriously went in looking for that, and managed not to see it

#

but I just checked again and it's there.

#

well, thank you :)

feral merlin
#

Can someone help me set up teleporters?

frozen bobcat
feral merlin
#

Okay so I set up a teleporter system but need help

#

I don't want to rotate the player at all when teleported. How do I preserve the player's current rotation value?

grand temple
#

you can just get the player's rotation

#

from the playerapi

#

there are some situations where this will not preserve rotation perfectly, but it's good enough. It's only wrong if you twist and tilt your head in a particular way

feral merlin
#

The issue that I'm trying to fix is that if you walk into it backwards it starts teleporting you back and forth like crazy

#

So how do I set it up to get the player's rotation?

grand temple
#

playerapi get rotation

#

it's a node, search for it

feral merlin
#

Gotcha

#

Real quick

#

What do I plug into the get rotation?

unknown.png
grand temple
#

networking get localplayer

#

or since you're already checking if they're the local player, you could also plug in the player from onplayertriggerenter. It's the same thing

hi im having trouble finding information or anything that could help me learn about player anchor.

for example i have a hat item in a world then player can pick it up put in the head and follows even when the player move.

cold raft
#

You can get the tracking data of a player, I think you need that and update the position of the head each frame based on tracking data

pallid remnant

is there a way i can force a player to sit on a chair in interact in sdk2?

# grand temple networking get localplayer

Related question I want do the opposite: I have a teleporter doorway And if they sidestep into it I’d like them to pop out of the destination rotated sideways. I’ve done pretty much every rotation operation I can think of I thought I would just divide the player rotation by departure object rotation and then multiply it by destination rotation but it didn’t work

grand temple
#

don't divide by it, multiply by the inverse

pallid mango
#

Quaternions, man

pallid remnant
#

but is there a way to force them off 🤔

So it turns out there are now Quest worlds popping up with working youtube players, how does this work? Does anyone have info how to replicate ?

And to be clear the whole YouTube-DL situation is Google’s fault.

fiery yoke
pallid mango
#

If YouTube were owned by a different company we’d have an easy to use api to play YouTube videos in social vr platforms. It’s their fault it doesn’t exist.

fiery yoke
#

But then they couldnt enforce ads :P

pallid mango
#

If they made it they could find a way to do it

#

But they didn’t provide a solution at all so other people did

pallid mango
#

As Google, if you aren’t going to provide a way to property watch YouTube videos together online on external services in a way that works with your ads and everyone can use it fairly, and are going to leave it up to end users to make those tools… they should have expected ads would be the first thing to go in the user-made solution. YouTube-DL couldn’t serve syched ads even if it wanted to. Only Google could have made that service.

chilly crater
#

What layer does the player's mesh render on?

#

well, localplayer

fiery yoke
#

The full player mesh is on MirrorReflection

chilly crater
#

I'm doing an OnPostRender texture grab from a camera and comparing the color of a pixel.

#

Is mirror reflection localplayer only?

fiery yoke
#

yes

chilly crater
#

mmkay. that works out better.

#

Okay, it works now, thanks.

#

I just have to figure out the most optimal pixels to compare for the camera.

Heya, probably overthinking here. But some questions:

  1. When a player spawns, isn't there an accessible gameObject of that player's transform and other data? Or we do just fetch all of that from the VRCPlayerAPI? I can't recall but I watched a friend spawn new players in CyanEmu and it activated/created gameObjects for each spawned player, so it could be instantiating them on player join?

  2. Is tags the best option for handling player specific data, or should I just have a gameObject behave as a datasource that is sync'd that holds the player and "arena match" data? (I thought about writing a very simple Udon SQL engine that I could toy around with very basic statements to manipulate data in said datasource).

Is there any method to see how long an object has been interacted with? for instance I got a object that i want to click and do something, but i would like to click it for longer and have something else happen. sorta how right click works on touch screens

hello, im new to using udon, but ive looked at the example scenes, and ive read the docs on the nodes im trying to use. to the best of my understanding the layout i have should work, but it simply is not. anyone mind takeing a look and helping me figure out what is wrong?

#

im trying to make an elevator script, when the player is an the collision area, and jumps, they will be teleported to the destination

pallid mango
#

The white arrows should always be used. That is the order of instructions.

Green nodes are starting points. Your starting point for Jump has a white arrow output that isn't being used - this means it's not doing anything. it needs to be connected to it's first instruction.

sweet spoke
#

so where should i connect input jump into? someone told me i shouldnt have two likes going into the same block and that it will not work...

#

so, i tried it out, and it worked once, but now it will not take me back up...

pallid mango
#

I would create a bool varible. It does not need to be public. The output of InputJump should go to a Set value and carry over JumpInput's bool to it so the value is saved to a parameter whenever they press or unpress jump.

#

now you have that varible to use in your other event when they are staying in the trigger, and you can check if the bool is true

#

I'll scratch it up if you like

sweet spoke
#

i think i get what you are saying, give me a minit to try it out, i need to learn...

#

good?

pallid mango
#

More similar to this

flint urchin
#

To the post above the one above; Almost, unless the gameObject is set to only interact with the local player, you need to add a local player check

pallid mango
#

Typically, SetProgramVarible is only needed to set varibles on other udon scripts. To set a varible within the script itself, you can just use the Set command. created by holding CTRL and dragging a varible out of it's floater. (if you don't hold ctrl, you create a get value. hold ctrl, you make a set value)

#

but what you did still works!

flint urchin
#

Also, in the picture (to Aaronstar) you use while, use branch instead.

While is only used if you want something to happen over and over if the input is true

#

Which is not something you’d want to do when teleporting someone

pallid mango
#

(Branch is If in the node world)

sweet spoke
#

oh, the and gate is called logicaland, good to know. i was looking for that for so long...

pallid mango
#

i have a habit of minimizing my nodes, so any unused connectors are not visible

#

probably should not do that when giving examples

sweet spoke
#

so im realising not all results will come up when searching, sometimes you need to know the parent result to find the actual node you want...

pallid mango
#

Right, node search is two-phased. first you search the class, then you search the methods of that class

#

so for logicalAnd, first it's boolean, then and

#

(the class is the small text at the top of the nodes)

sweet spoke
#

yea

pallid mango
#

An option for a global search would be handy, but in reality the list is insane.

#

almost all of UnityEngine and MonoBehavoir is in there

#

You can use Unity's monobehavoir documentation for most of Udon - since except for the VRC classes, it's all the same

sweet spoke
#

hm, so if someone is holding jump they will be quickly moved back and forth...

#

also, is it possible to get other inputs then jump like crouch?

pallid mango
#

I don't think crouch is in the input event system, but there are ways to detect it

serene moat
#

you can do a global search by pressing tab

Does the event of 'inputuse' always run like event update? or only when used? Perhaps there's some examples I can look at?

cold raft
#

Update is run every frame, other events are not and instead only ran when thier corresponding event happens

zealous mason
#

alright, thank you. Just trying to figure out how to check if the button is released if the event isn't running 🤔

grand temple
#

it sends you an inputuse when the state changes, and it gives you the value. It will give you a false when you release

zealous mason
#

oh so it only happens for one shot? one for button down and one for button up? Thats perfect, thank you very much!
