udon-general

[last geyser]

Dang, I wonder the complexity for Graph

[junior lava]

I have much more experience in C# so I've always been working with U#, I'm just more familiar with it.

[last geyser]

I would try to use C# but, I lack experience in it

[sand basalt]

@last geysercreate int var, and use addition node each time someone interacts with object

[last geyser]

Should the same int parameter be used or should there b different ones?

[sand basalt]

if you want it to count, oc it should be the same

[last geyser]

Gotcha, I was thinking of the animation parameters or if im mistaking it for Udon's Int

[sand basalt]

yeah udons int

[fiery yoke]

You can't. The only identifying piece of data you can get is the displaName, however it may change as the user can change their display name once every 3 months. VRChat has not made an official statement AFAIK if it's intentionally that way, but from what I know, they want to prevent people from targeting or excluding specific users based on their ID. However the display name is pretty much identifying enough usually so yeah...dunno.

[last geyser]

Gotcha, This would be a first time using Int as I never have used it. Which option of int would increase its number from each usage?

[sand basalt]

smth like this

[last geyser]

Question The Set Counter would be created from what and also the Counter (My mistake for not knowing)

[sand basalt]

its variable you create in left corner, you drag it out, and drag again while holding ctrl

[last geyser]

Alrighty after creating that all, in the Set Counter Can I just connected it to an Animator Set Bool?

[sand basalt]

its int...

[last geyser]

Oh, So from creating all this, Every time I interact with one of the Crates I wanna collect. The Int will increase?

[sand basalt]

Int will increase after custom event is triggered yeah

[last geyser]

Strange, nothing happens

[sand basalt]

show your graph

[sand basalt]

you have 25 boxes and want a certain animator to play clip when a person click on each?

[last geyser]

Yeah, each box clicked will increase the counter

[sand basalt]

For starters you need script on each box that sends event (not network btw) to counter script, and disables collider on it (so person wont be able to click more and add counter on same box). Counter script starts like i showed, but checks if counter reached 25 before adding, and if it equals 25 sends bool to animator. you dont even have to send parameter to animator, there is a node that just plays clip you want

[last geyser]

Yeah i've had scripts on each Box so I could test it. So if im correct, the animator layer should have 1 with at least 25 States all sharing an int Transition with a different number that it expects to equal on. and with the script on it, With interacting with that said box, it should automatically increase its int counter correct?

[sand basalt]

this scripts does counting, you dont need to involve animator

[last geyser]

Gotcha, and after its reached to that specific number, How would it know that it should trigger something?

[last geyser]

so as an example, if its clicked 25 times, it will trigger the Setbool Animator correct? If so its not working

[sand basalt]

start checking everything and looking where you made a mistake then

[last geyser]

Idk, I kinda been checking a while and haven't found the cause

[last geyser]

So apparently the animator was corrupted or something so I re did it and it worked

[vestal nimbus]

Thank you for your reply! I will use DisplayName for identifying a specific player for this time, thanks a lot!

[last geyser]

Ok problem with the script, It only applies to one object, Not different ones combined.

[sand basalt]

What?

[last geyser]

Yeah the script only works with one object, as an example after collecting all 25 boxes it doesn't work. Even with the same script on all of them, They will all remain on the count of 1. But when I add one box that never despawns and I click it 25 times then it works. So its not combining

[sand basalt]

You need 1 counting script on empty object, and 1 script on each box that sends event to single counting script. I think you took upon yourself too complex task to start learning udon. Start with more simple things to understand how logic works.

[last geyser]

Yeah, I have done Udon for some time but I haven't expanded my knowledge on stuff really

[sand basalt]

Take it slower, make stuff just a little bit more complex each time. There is also a networking part, which will complicate all this even more.

[last geyser]

Yeah, Ik for this one, Its something complicated and well I wanna learn it a bit more since, I wanna be able to create a map with this script

[wind atlas]

Is there any way to trigger a submit event on a button? onClick.Invoke() isn't exposed.

[last geyser]

But atm do I just need to create a different script on the empty and make the box scripts send signals to that one?

[sand basalt]

Yeah

[wind atlas]

Alternatively, can you get the EventSystem in the scene? Something like 'Find("EventSystem")'. I feel like that won't work either.

[last geyser]

Ye dunno, I got that other script for only 1 object but wouldn't know how to send signals to the empty.

[vestal nimbus]

Another question about Udon, is there any way to change "Interaction Text" of interactable object by using C#?

[ebon musk]

Does anyone know how I would make a gameobject spawned on a player on join remain positioned in relation to one of their skeleton bones? Would I need to make another graph, or just another event on update, and if so, how do I tell it what the gameobject is without using the Trytospawn, is there another way to return the objectpool object currently assigned to that player?

[tacit harness]

So im making a video player in udon and i wanted to use a slider so you can skip throught videos

Now i have a slider that at the beginning of the video sets the max value of itself to the length of the video that is playing

Then i have a on value change that is connected to a synced float that gets the value of the slider and puts it in there
Then it sets the time of the video player to the one you skipped to

Now idk why but as soon as i add it exactly like that the video player just breaks even when playing normal songs or so

The person selection the video is fine but everyone else isnt loading in no matter what i do even resyncing it manually does nothing at that point

Me and a friend have been trying to do this for so long now and i dont really know anymore

I know there are two missing things dw abt those tho i know that they are missing in the backup script that i took the screenshot in

[ebon musk]

Is there a node that returns a gameobject that is owned by the localplayer

[junior lava]

I always thought sliders have to be mapped from 0 through 1? I always roll with that assumption and then call a remap function from there to map it to the range I want.

 private float Remap(float from, float fromMin, float fromMax, float toMin, float toMax)
    {
        var fromAbs = from - fromMin;
        var fromMaxAbs = fromMax - fromMin;

        var normal = fromAbs / fromMaxAbs;

        var toMaxAbs = toMax - toMin;
        var toAbs = toMaxAbs * normal;

        var to = toAbs + toMin;

        return to;
    }

In your case, fromMin = 0f, fromMax = 1f, toMin = 0f, toMax = movie.Length

[ebon musk]

Does anyone know how I would go about making an object return to the pool after the player it was spawned for leaves the server?

[midnight vault]

Hellow friends, i would like to know if it's possible to make a button for "if someone interact, this player is the master" ?
I have try this for some objects but it's not working.
Someone have a idea please ? i don't find a answer in UdonDocs

🥺

[grand temple]

You can set owner of objects, but you can't change the master since the master is always the person who has been there the longest. That graph should work for setting owner, is there something else you want that it's not doing?

[midnight vault]

My goal is to redefine the Master if it disappears from the world (crash) and comes back after

[grand temple]

You cannot change master. You can transfer ownership of everything, that's probably what you want and it seems like that graph is able to do that

[midnight vault]

Okay, I have an idea then, I'll change some things in my world and I'll let you know. Thanks for your help

@grand temple So in theory, this is better ?

(without Networking event i know )

[grand temple]

Not really, that's just going to give ownership to whoever is the last person to join

What are you actually trying to accomplish? Just giving ownership isn't really going to do stuff unless you set variables

[midnight vault]

Sorry i try.
I give access to some triggers for the Master. But if this one disappears and comes back in the world, I would like to give him back this possibility

[grand temple]

In that case you could give access to the instance owner with IsInstanceOwner. Instance owner is the person who created the instance, or if it's a public instance it's just the world author

[midnight vault]

Oh i see yes, the key of my sucess so is this "IsInstanceOwner". i will try TY

[midnight vault]

Oof, i hope this is better 🙏 @grand temple

With the Good name of the custom Event "i fix"

[grand temple]

don't plug it into isvalid. Bools are always valid even if they're false, so it's always going to be true

use a branch instead, that splits the flow based on if the bool is true or false

[midnight vault]

Okay, 😉 Thank you ^^

so much !

[pallid burrow]

is there a way to make a killbox like in 2.0 for objects?

[shut ermine]

is there an udon sharp unity package or, do i have to drag the udon sharp folder to unity

[pallid burrow]

its on the VRCPrefabs website

[grand temple]

make sure you're looking at the releases page, it's a unitypackage

[shut ermine]

is there another car prefab out there that isnt simple cars or the go kart one>

[compact bluff]

@midnight vault do you know how to make light sliders and world toggles?

[thorny bane]

Anyone know how to deal with world master lag?
i have a issue where only world master gets bad fps rest are like 90 fps

[desert grove]

If it's only the master how many synced events are you pushing including pickups. Basically everything synced updates the master so the master would be hit with lag before everyone else. That lag would cause data loss which would mean that the masters updates to the other clients would be sketch so others wouldn't get the lag because they arnt getting all the updates.

[thorny bane]

alright, is there a way to see how many are going off

[desert grove]

you could try setting up the debugger. Read the doc for your setup, but I am not familiar with the newish in game debugger. https://docs.vrchat.com/docs/debugging-udon-projects If thats too much or doesnt provide enough information, start by disabling as many interactables as possible. If all you are using is approved prefabs from vrcprefabs then the coding probably isnt the issue, it might just be the quantity of synced events.

[ebon musk]

How would one go about making a puckup follow every player from an object pool, and disappear when said player leaves

[compact bluff]

does anyone know how to make a slider control multiple light sources?

[tacit obsidian]

how can i make an animation play when being toggled from a button? this has become alot more confusing than sdkw2

[desert grove]

Animation > Play > ClipName
or if using the Animator (Animation Controller) You assign a bool for determining if the animation plays just as before, the button is then setup to get the Animator component and SetBool > Yourbool to true.
It's not more complicated, you just learned to write with the wrong hand first. sdk2 worked but it wasnt wise. You'll get it

Thankfully you no longer have to look up outdated sdk2 tutorials on youtube, any Unity video on your topic of choice will point you in the right direction.

[twin hedge]

Ok, I had to update UdonSharp. I removed the last version folder and put in the latest version of UdonSharp. But now the sdk option is gone, and i got 52 error logs. I'm using the latest SDK. So, how do i fix this?

[scarlet lake]

does anyone know where i can get the text chat for worlds

for mutes

[desert grove]

https://docs.google.com/spreadsheets/d/e/2PACX-1vTP-eIkYLZh7pDhpO-untxy1zbuoiqdzVP2z5-vg_9ijBW7k8ZC9VP6cVL-ct5yKrySPBPJ6V2ymlWS/pubhtml#

[neat flicker]

Do I have to add something to Audio Reverb Zone to make player's voice echo

[spice wind]

anyone know what this would mean?

[wispy atlas]

Audio Reverb Zones won't affect player voices. If you want player voices to be heard with reverb or an echo applied, add an Audio Reverb Filter component to the main camera in your Unity scene that has the Audio Listener component (the Audio Listener component acts as your ears in game). Player voices will now have reverb applied, but also every other sound you hear will as well (VRChat UI sounds and any audio in that world) because the Audio Reverb Filter is applying its effect to every sound heard through the Audio Listener

[spice wind]

I think im just breaking this more, Im really not sure what I did lol

[desert grove]

It's hard for me to tell what is really going on without seeing the top few errors, but usually you follow one of these steps:
*Press clear in the console - If everything clears, move on.
*Reimport the SDK by selecting VRCSDK RClick and choose reimport

• Reimport the DLLs by navigating to VRCSDK > Plugins then select all DLLs and RClick and reimport.
  If your errors are caused by a C# script not associated with VRC those need removed. If the Errors are caused by a a script you wrote, they need fixed.

[spice wind]

I'll do that, thank you! It all broke when I imported a world prefab and it doesn't seem to want to fix itself

I deleted the world folder, even made a new project without it and started fresh, but everything's busted

[desert grove]

Asset store product?

[spice wind]

Nope, booth

I'm using SDK3 so idk why is complaining about 2

[desert grove]

Oh so it is a premade VRC room? A lot of premade booth/gumroad world devs organize their projects in a way that breaks when updating to a new Unity/SDK. You might have to start a new project, import the booth, make sure you are in a blank scene and remove all SDK related folders and then reimport.

Those are sdk2 errors, you cannot have sdk2 and 3 in the same project.

[spice wind]

That's weird as I never imported sdk2, unless it came in the world's package.
I was using that booth prefab as a second room for my main one. Already made a new project without it and it's completely busted. Do I have to restart from scratch?

[desert grove]

Not if you can remove all offending assets. It will just start working again if you get it back to one sdk. SDK2 projects usually have Standard Assets (an old unity thing) as well so if you remove all sdk2 stuff, you have to remove that folder as well or it will still be broke.

[spice wind]

Alrighty! I'll see what I can do, thank you!

this is what im getting now lol

Should I delete Cyan?

It was working before

[desert grove]

They are freaking out because of the Udon issue. Once you have Udon alone and UdonSharp (pool) and no SDK2 stuff those should go away.

If you are trying to remove all VRC related stuff and just get back down to the physical buildings then yes, remove it all

removing everything is going to remove all your mirrors/buttons and video player fyi

[spice wind]

Ah damn, alright

So delete every VRChat folder?

all of these?

[desert grove]

Thats a mess... Do you have a backup before you imported the booth world?

[spice wind]

Unfortunately not

Unless unity makes backups, no

[desert grove]

nope, always backup. Do me a favor, backup now. close unity navigate to where the project is stored, and zip the folder.

[spice wind]

I don't think this one can even be saved though, I'll just restart. I have w ayyy too many assets to even attempt a backup with all the broken stuff with it

I can back it up, but honestly Ill probably just remake it from the beginning. Lesson definitely learned lol

[desert grove]

yeah you have like 4 or something VRCSDK3 folders, something is wrong 😛

[spice wind]

Pfft, yeah, I have no idea what I did lol

[desert grove]

you can save your physical work by selecting the scene in the project window, and choosing select dependencies. Then go to assets and choose export package. Uncheck include dependencies and uncheck anything that says vrc. then export. Your rooms + materials and lighting will be saved. then you can import it into a new project.

[spice wind]

I can try that again, tho some of my things have Udon Scripts and I think that's what broke the second one

[desert grove]

Yeah, uncheck all scripts when exporting. Go for a clean rebuild keeping your physical work.

[spice wind]

I'll try that, thank you!!

[spice wind]

Ey no missing scripts now! Just have to redo all my Udon scripts and such. For the backup, is it safe to just import the entire thing 'SDK/Udon' into a new project? Or is it required to set that up fresh everytime?

[desert grove]

if your errors are cleared you should be safe importing the sdk3 now. SDK then UdonSharp(Udon is not UdonSharp), Udonsharp is needed for the pooltable you had.

[topaz maple]

isnt udon a kind of sushi

[grand temple]

Udon is a type of noodle

Udon graphs connect nodes with noodles

[spice wind]

Oh everything's safe and set up! If I export a backup package with Udonsharp and the sdk, is that safe to put into a project like that? Or would I need to push in a fresh sdk / Udonsharp before importing the backup? Just in case anything goes wrong again

And indeed 👀👀

Udon is very tasty actually

[grand temple]

best to just not include sdk or u# at all

[spice wind]

Alrighty! Thank you!

[glass shoal]

Wtfffffff

[spice wind]

Lol

Yeah I was stupid in how I tried to fix that

[glass shoal]

Crazy

[frigid lance]

@dusty mica

[valid totem]

Hey all, I'm trying to set an object as a child of another object and change it's position to just slightly above the parent object using this code:

Public GameObject Platter;

gameObject.transform.parent = Platter.transform;
gameObject.transform.position = new Vector3(0, (float)0.003, 0);

when the method is triggered the object is relocated to near the origin of the world

What is the right way to do that?

going to try Transform.localPosition https://docs.unity3d.com/ScriptReference/Transform-localPosition.html

yep that worked

[desert grove]

Setup a GameObject array, in your toggle event run a for loop and set the collider component of the gameobjects to off and rigidbody component isGravity to false. If your pickups are kinetic then you can skip the gravity part.

[blazing crow]

I've searched this Discord and done a fair bit of searching elsewhere over the last couple days and haven't come up with anything so I hope this isn't covered somewhere else:

I may have a tiny bit of a fascination with shrinking. I've learned how to create tiny avatars in Unity and I've fully given up on the dynamic avatar size control that was apparently removed from Avatars 3.0
...but...
there is a world called "Shrink House" that seems to shrink your avatar dynamically as you interact with objects/stations in the house. Does anyone know how this is accomplished?! Do the stations really shrink your avatar? Is it some trick with making the world larger? Is there a reason it's a solo world - do the transforms not sync between players?

I'm still pretty new at developing with Unity, Udon and SDK3 and I'm hoping this isn't just Udon 101. I'm just looking for a place to start so I can try to create my own version(s) of worlds similar to Shrink House. Thanks in advance!

[desert grove]

I don't know about that world, but this is usually faked, especially if its a single player world. Clicking on a chair moves you to another chunk of the world when everything is scaled up. No need to actually change the scale dynamically. You can further improve the concept making it multiuser if you use RenderTextures with a camera. So you can display the normal room to the tiny people looking up, and another one displaying the tiny people to the normal people looking down. In actuality all people are their normal size.

like a prop like this is setup on a table https://laminiworld.com/image/catalog/sub_banner/sub_banner_frame_box.jpg when you click it you are then teleported to a large version of it about 1000 units away.

[balmy solar]

If I just want to change the x position of something, how would I do that? I tried getLocalPosition > SetX but it didn't work. There's also SetLocalPosition but I don't know how to set individual values from a float variable

I just made a parent object and setActive>False for the parent object locally

[elder peak]

use the vector you get from the getter, change x, assign in the setter

[balmy solar]

SetX doesn't have an output

[elder peak]

i was referring to setlocalposition

[balmy solar]

I mean, how do I change the x position?

[elder peak]

i already explained the first step
and then you use setlocalposition

[balmy solar]

I mean how do I actually alter the Vector3 I get from GetLocalPosition

I can't find a way of altering it

I have a float value I need to set to the x position on the vector3, but SetX doesn't seem to do anything and I can't find another method to actually change the vector3

[grand temple]

vector3 set X

but you'll have to save it to a vector3 variable first

[balmy solar]

Oh that makes sense.

[elder peak]

are you sure? i assume you can simple use that vector3 you set again

i just tried it and the set value remained

so it seems that a variable is not needed

this printed a vector with -55

[grand temple]

Ah, I didn't expect that to work because it doesn't return anything. That is a bit of a weird node

[elder peak]

mhm, it got me curious!

the more we know

[balmy solar]

I agree, not only is it counterintuitive, but it's also destructive. In visual coding there should be a clear flow from input to result

Thanks both of you, though!

[grand temple]

yeah, for that reason I would probably recommend something like this instead

[balmy solar]

Oh I didn't know there were constructors

That would've helped me a lot

[elder peak]

yes, that's a good and clear way

[balmy solar]

Mainly because I'm only using GetLocalPosition to get a Vector3 to work with, I don't actually need the current position

[blazing crow]

Thank you! I suspected as much - it's all smoke and mirrors... mostly mirrors. 😄

[balmy solar]

And don't forget the mirrors ;P

[blazing crow]

All of the mirrors! 😄

[shut ermine]

How can I add a climbing mode?

or like double jump to udon

[uneven flint]

okay idk what i did to udon but its not working for me anymore

this is setup on my original mirror as a toggle and it works

i have the same stuff on this one but it makes the toggle go invisible instead of the mirror

[valid totem]

I have not tried it, but here is a U# for a double jump

https://gitlab.com/-/snippets/2125069

[valid totem]

Is the script is a component of the button for VRCMirror2, and VRCMirror1 is unused in that graph?

[shut ermine]

This costs money

[uneven flint]

yea it says 2 cause i re entered the mirror to see if that would fix it

[valid totem]

https://github.com/squiddingme/UdonAirtime maybe?

[uneven flint]

im thinking maybe delete the udon script and then restart it

[valid totem]

What part of this cost money? I just implemented this and double jumping works without having bought anything. Attach to an empty gameobject in your world https://gist.github.com/pyralix/ec12959fdf91b812fa8e8a354fe1a827

[desert grove]

make sure to check the script over. It is using Udontoolkit so you will need UdonSharp and Udontoolkit installed (never used udontoolkit might be this https://github.com/orels1/UdonToolkit)

[valid totem]

Udontoolkit was an unused reference

[tranquil acorn]

How do I sync a pickup object? I test my pick up with two clients, the pick up didn't sync at all, one pick up the item, other see the first one holding thin air and the object is still on the ground

[grand temple]

add the VRC Object Sync component

[tranquil acorn]

Got it, Thanks you so much bro, I been asking this question on reddit and other discord server, never got a reply😂

[fallen chasm]

I've got a really basic script set up to switch fog values with a trigger zone and I'm curious to know if it's possible to set a transition speed or time between two states with udon (and not animators).

The behavior is fine when jumping to new locations via teleports, but my goal is to have the world fog adjust gently when passing through a doorway.

[grand temple]

You could set a "target value" and then on update, lerp to that value

also, you need to check if the player is local. If you don't, this will set the fog when you see somebody else walk into it

[fallen chasm]

I'll be sure to add the local check

didn't know I could lerp things in udon

I'll test it out -- thank you

[hushed gazelle]

I've seen some worlds manage to create an area that give player speech an echo effect like they're in a large open room. What's being used to create that? (Aside from the obvious of a trigger space to enable/disable it)

[opal dew]

Is it possible to detect the tracking type of a particular player? AKA, if they are desktop, VR or FBT?

I know desktop or VR is possible, its the latter I'm not sure on

[desert grove]

Just between desktop and vr. All system specific controls are handled under the hood now. We don't code for particular keys or buttons anymore, or well, we don't need to... Still see a few trying. You can quickly find a list of bools by searching the nodes for "is" or just type is in VS and scroll through the auto complete.

[opal dew]

Yeah. I did search all the usual places but couldn't find anything. Searching the history here, other people have had the idea I had about showing a mirror when the user has for example, entered the FBT calibration state. In my case I'm adding a mirror that appears around my spawn point in my homeworld if a) its me, checked by username and b) its within the first four minutes of starting VRChat. The mirror then dismisses if I step off my spawn pad.

[hollow widget]

Do you know how to script udon to delete objects we spawn?

[vestal mica]

Does interact only work on one object max?

[hollow widget]

like this
https://youtu.be/tc76vkOSDms
it can spawn object but can not delete objects we spawn

[vestal mica]

Thanks I'll check it out

[balmy solar]

Are you instantiating objects? VRChat does not like that, and it wont work over networks either.
What most people do is have X number of pre-existing objects and then show and hide them as needed

Anyone know if Object Sync syncs the object's parent? It's not working for me and I'm not sure how to do it

[balmy solar]

Still need help

[elder peak]

no https://docs.vrchat.com/docs/vrc_objectsync

[balmy solar]

Is there another way to sync the current parent?

[elder peak]

what problem are you trying to solve? this may be an XY problem

[balmy solar]

I set to object as a child of another object but it doesn't follow the object's position for other players

There's also code i run against the object's children so if they're not properly set as children it doesn't run

[elder peak]

but why do you have to change the hierarchy's structure?

[balmy solar]

I'm moving cards between different player's hands, so the card needs to follow the deck a given player is holding

[elder peak]

and changing the transform values when the player switches won't work?

[balmy solar]

With my game logic, it's easiest to imagine a bowl, and when I add fruit to the bowl the fruit moves with it, and each player has a bowl.

[balmy solar]

I have to do a lot of math to spread the cards out and move between decks that the players may or may not be holding. Setting the cards to children of the current deck was my first choice. It works perfectly fine just other players cant see what each other does, but for them it works great. I just need to sync between players

[valid totem]

If you have some gameobject that always relates to the hand (the bowl), I think you could assign the bowl as the parent, toggle kinematic, and place the fruit in one of many pre-designated locations that you can check if their empty or not

then when you pickup again return the original component values

[balmy solar]

Isn't there some way to just tell a script "this is your parent, go there"? I tried using a string with the name of the parent but I'm still new to networking so I was having issues

[valid totem]

or even enable/disable rigidbody altogether

yeah there is and with objectsync on it networks pretty well

[balmy solar]

They're always set to Kinematic. I never want them to have physics

[valid totem]

I'm just thinking that if you want it to stay at 0,0,0 of the parent you may need to disable the rigidbody or make it kinematic so maybe that's no prob then

to set the position of a child object relative to its parent

gameObject.transform.parent = parentObject.transform;
gameObject.transform.localPosition = new Vector3(0, 0, 0);

[balmy solar]

I know how local positioning works, the problem is it wont let me set transform.SetParent() for other players

This here. It works fine locally, the object works exactly as intended, but nothing changes for other players

[valid totem]

You need to tell the other clients to do the same thing either with a network event or a sync variable that you deal with during ondeserialization

[balmy solar]

I have no idea how events work

[dawn sleet]

hopefully easy question - in an udon graph, how do you set a new texture for a gameobject? i've been messing around for like two hours and am having trouble with it

er, new material

not new texture - though, i guess the material has a new texture... lol

[balmy solar]

Yeah so all our conversations are gone from the past two hours.. hope no one was still needing help..

[dawn sleet]

lucky me, getting here just in time, then

this is what i had set up just now that wasn't quite working - also tried with MeshRenderer, among other things

[balmy solar]

I had this issue before.. I think I had to use something like meshRender.materials[0] = newMaterial instead of meshRenderer.setMaterial(newMaterial) (whatever the equilivant is uGraph)

[dawn sleet]

so probably meshRenderer[], i assume?

i'll poke around with that, thank you!

[balmy solar]

No, that's a list of meshRenderers. meshRender has a variable called materials[] that contains the multiple materials of the object. GetMaterial/SetMaterial is supposted to get the first material from that list but it wasn't working for me

[rancid geode]

I had like 4 pings from this server, I wasn't able to find them.

[dawn sleet]

ahh, gotcha, i'll see if i can get that to work then! thanks

[balmy solar]

Bot raid like 15mins ago

[dawn sleet]

man i am so lost in the sauce

still not workin, maybe i should just make a script LOL

[valid totem]

When I try to make a new VRCUrl object I get this error:

System.Exception: Method is not exposed to Udon: Void .ctor(String), Udon signature: VRCSDKBaseVRCUrl.__ctor__SystemString__VRCSDKBaseVRCUrl

Is there a way to create a VRCUrl without having a VRCUrl input field?

var url = new VRCUrl(gameObjectName[1]); throws that error

trying to take a string and send it to a videoplayer without user interaction

[topaz jetty]

you can't make new VRCUrls at runtime without VRCUrl input field. You can make them beforehand though with a variable not made at runtime

private VRCUrl URL =  new VRCUrl("Your URL here");

[verbal sparrow]

Dunno if this is the best place to ask, but what are these other modes mean for the VRC AVPro Video Speaker Script? Like the Three, Four, Five, and so forth?

I cannot seem to find them documented whatsoever in the VRC Docs.

[valid totem]

Thank you!

[strange minnow]

Is it possible to persist data outside of a world? For example, save high scores to a database? I was looking through the API and don't see accessible ctors for VRCUrls or get/post methods on a web client, for example.

[sinful slate]

nope, not at the moment

[scarlet lake]

Is there anyway to fix this from happening in screenshots?

Have post processing and occlusion on, and was curious if there's a way of fixing it, without having to get rid of occlusion?

[broken bear]

there's two methods, hashing a string that they copy and paste later like the Udon Chips save system, or using nesterboy's avatar saving system that uses Udon to write save data onto avatars then you can load that same data into the world later. A bit more advanced bit you get lots of bits to work with

[strange minnow]

Interesting, thanks for the pointers

[sinful slate]

I remember that vrchat wants to implement a localstorage system at some point, which would at least allow you to save settings and gamestate

[strange minnow]

I was just reading about the PlayerAPI variables that they're intending to allow you to get/set, so that also works (when it's released)

[grand temple]

Try going to the open beta of VRChat, it may have been fixed. If not, make a canny with a link to the world where this happens

[lime merlin]

Is there anyway to remove the picture of the avatar from a pedestal or make a behavior to select an object and change avatars without that picture?

[hollow widget]

https://youtu.be/O3VeBzV9HgI

[valid totem]

I want to release some of my Udon work as prefabs, any advice of things to consider before doing that?

[hushed gazelle]

@lime merlin Change the target avatar pedestal position transform to a scale of 0. (The one that sets where the picture appears).

[lime merlin]

I did, but the picture still appears and it's actually huge now

[plush stump]

how to make a UI that follow the player's view like the among us map? Right now I'm using headbone as archor point but I want it to slowly float to the target position rather than instant.

[hushed gazelle]

@plush stump Look up how to write a third-person camera for Unity, it's actually pretty simple. The trick to make a good camera that follows and isn't just anchored to the player's head, with all the flailing around that brings, is a combination of LookAt and SmoothDamp. You'll want to set an offset rather than the player's head directly, so it follows from a point behind rather than AT the head. This'll do it (it's how my RC car's DriverCam works)

TargetToFollow is a second offset value (in my case it's so the camera looks slightly above the car rather than right at it for a proper third-person camera)

[lime merlin]

wait I just got this now, ty!

[dense imp]

What script do I put in the area that says somethings missing?

Its for a mirror switch

[grand temple]

If you received this project from someone else, you should probably ask them

[dense imp]

Its just one off booth from a japanese peep, I dont mind re doing it myself just wondering how?

[grand temple]

Here's a video that shows how to set up a mirror toggle https://www.youtube.com/watch?v=ibDu0dCeUE8

[dense imp]

Awesome thankie

[plush stump]

If I use Constructor nodes to create an array called 'String_Array', and I want to create a new 'String_Array' , do I have to clear the array first or I can just use constructor nodes again to replace the old array?

[wind atlas]

You should be able to replace "String_Array" with a new array. The old array should be cleaned up in the background if it's not used anymore.

[obtuse agate]

it's the number of audio channels

[dawn sleet]

sorry, i know i'm hours late, but:

1. make sure you list all dependencies (i.e. poiyomi, the sdk, etc)
2. add a short text file guide for import
3. ideally you'll want small texture atlases for better load time/file size as well
   also be sure that you are exporting it as a .unitypackage!

not sure what else to suggest - i guess add a policy on distributing modified versions of your udon work

[valid totem]

lol no problem thank you for giving feedback to that question!

[dawn sleet]

👍 np!

[valid totem]

Yeah I see some people sell their work others make it public

in either case licensing comes to play... probably not a topic for udon-questions channel exactly heh

[dawn sleet]

yeah i figure not - but good to look into!

[uneven flint]

can udon be used for any programming that youd want done in the world

like teleporting, picking up items, changing the lights in a room

is that all done through udon or no

[elder peak]

yes, udon is your workflow to define logic in your world

[uneven flint]

anyone have a video that covers basic stuff like that then?

[uneven flint]

im looking into pausing world music

with a button

any tips or leads

[dapper lion]

vowgan youtube tutorials

[tranquil acorn]

So I followed vowgan's tutorial and made a flying glove, but I fail to understand what does this get forward means? It only said transform object on z axis, but what about the force? Also it said transform, does it mean it simply transform the object instead of adding force to it?

So I have a plan to make some different variant of fly gloves and I want them to have different thrust and mass, how should I do that?

[slim crow]

Is there a way to set or get the url attribute of a video player using udon?

[cunning mist]

"Forward" is essentially what the blue arrow is when you've clicked on a gameobject. If you don't plug anything into the "Instance" slot, it will automatically get the forward of the gameobject that the Udon Graph is on. So basically, it's just saying "Which direction is this object looking"

[fallen chasm]

I've applied some lerp! -- but I'm running into an issue where my script happens instantly. I suspect it's because it runs once on triggers and needs to be reworked in such a way that updates on each frame.

(sorry to @ ya, figured you might be interested since you had an answer earlier in the thread)

[indigo finch]

Might help ya: #udon-general message

[fallen chasm]

ah, I'll take a look

I totally missed that -- it's a much smoother way to handle it too

thanks

maybe... well, still not sure how to incorperate trigger volumes, but I'm gonna follow your example on the time setup

[indigo finch]

hmmm... that example I posted might actually be wrong...
anyways, for your case, whenever you hit a trigger, it plays on player trigger enter once. and only once.
What you'll want to do is make it switch a bool value to true. then, on the update node, have it checking to see if that bool is true and if so, start doing the lerp thing. that being said, it will then do it indefinietly, so you will want a float.greater than node testing if it is close enough to the target amount, and turn the bool off.

[fallen chasm]

yep -- I'm working that out now -- an update that feeds a branch, which can be toggled with custom events.

(still working out the order of things)

hmm... maybe just bools, probably don't need custom events

[indigo finch]

for the gradual lerp, you will want a min, a max, and a current lerp amount. keep adding a little to the current lerp amount each frame till it's past 1 and your golden

[fallen chasm]

haven't gotten that far 😛

kinda hung up here

I do have a min/max -- not sure where I'd plug in a current value

is Mathf > Lerp not the right thing to use here?

I feel like I'm forgetting a really obvious node here... something that just sets a bool

I think I'm getting close

I'm not sure what that isn't working... no errors in the console :/

wait a tic..

[indigo finch]

here's some untested code for you to look over 🙂

[fallen chasm]

holy floats batman

I think my greatest flaw is that I always try to accomplish things using the least amount of code/nodes XD

lemme assemble one with your reference there and I'll report back

[indigo finch]

as you get more comfortable, you can easily see what nodes need what, and it becomes easy to add heaps of nodes. I don't claim this to be the best way of doing it, but it should help point in the right direction

[broken bear]

could you run OnCustomEventDelayedFrames and use that to incriment a float instead of update, that at least gets you a fixed tempo

[indigo finch]

probably/ possibly. I did multiply 'transitionSpeed' by time.deltaTime to make it fixed tempo though

[fallen chasm]

I figured that's what the delta time was for in your earlier image

sync up the transition speed with the playback?

[indigo finch]

and doing 'oncustomevendelayedframes' would avoid it constantly checking if the bool is true every frame. dunno how udon treats it though. i know back in unity world that calling a coroutine from the same coroutine is preformace suicide. Dunno if it is the same with delayed udon events

[broken bear]

callback should be fine with delayseconds instead of frames

[indigo finch]

hmm... okay. Guess I'll rearrange the code for the fun of it

[broken bear]

apparently delayedframes will queue up next frame at minimum so that's safe too

[indigo finch]

Something like this then

Was able to remove two of the variables. Weren't needed anymore

[fallen chasm]

aww yiss

interesting

so the delayed custom event replaces the event update?

[indigo finch]

yea, the update node was only there to delay it to the next frame

though my example didn't specify a delay. you would want to specify something more than 0. either that, or hit the dropdown and make eventtimeing based off fixed-update(every 0.02sec) instead of update (every frame)

or re-add the time.deltaTime multiplication

[fallen chasm]

time to test

oh no.... very flickery XD

must have miss-labeled or connected up the wrong node somewhere

[indigo finch]

transition speed should be sometime tiny. something like 0.02 would be my guess

[fallen chasm]

frame based rather than 'seconds' ?

[indigo finch]

don't think that should effect it...

[fallen chasm]

no, I mean... the transition speed value

or is that just like... a float being decimal values

[indigo finch]

the definition of a float is a number with decimals...

[fallen chasm]

hmm... low value worked to smooth the transition (which looks fantastic)

but it seems to only play in one direction

[broken bear]

your color and density inputs into the lerps are the same in both sets of count up and down

[fallen chasm]

right -- I'm just trying to figure out why the lerp accepts "time" with such tiny values instead of regular seconds

[indigo finch]

LerpCounter and transition speed are inverted. order of nodes only matters for subtraction, so that one will be bugged

[fallen chasm]

hmm... switched that, still getting one-way animations

weird

[indigo finch]

Lerp function has no concept of 'time'. it simply sees two numbers, and a float between 0 and 1. that final float says how much of number 1, and how much of number 2 go into the final result.
if the third number is 0.5, 50% of number 1 and 50% of number 2 will be in the final result.
if the third number is 0.25, then it will take 75% of number 1, and 25% of number 2.

[broken bear]

color input into the lerps are a-a b-b, should they be a-b b-a

[fallen chasm]

aaaah

lemme give that a switcheroo

[broken bear]

density too

[indigo finch]

Nice catch

Wait, nvm. colour density was already switched, but density wasn't. As the counter is counting downwards, it should be the same for both. The accidental switch might actually be the problem

[fallen chasm]

yea... something is still off

when entering the trigger, I get a slow a-b transition

when exiting, it snaps back to the start and repeats the a-b

so I just need to sort out what's happening in the exit bit

[indigo finch]

mind reposting the code with all the changes?

[indigo finch]

the fog colour inside and fog colour outside are inverted for the lerps at the bottom. as the counter is counting the other way, they should be the same as the lerps above them

[broken bear]

oh I see

hmm nothing is poping out at me on this as to why lerpcounter would follow the CountUp addition

[indigo finch]

yea, honestly now looking at it i could have done the same for the top as the bottom; flipping the lerp instead of the the whole count down/up thing

[fallen chasm]

I'm breaking apart the in/out nodes to make this easier to see

I've switched them up several ways and it still snaps

[broken bear]

snaps as in when you exit, it runs the inside->outside change again as if you just entered?

[indigo finch]

changed some things that might make it easier to understand code

[fallen chasm]

like abab instead of abba

you swapped subtraction for addition on the second bit?

[fallen chasm]

was the addition/greater than happening twice a copy/paste error or intended?

[indigo finch]

you were tending to flip the lerp values, but that seemed to be causing problems cause the counter would count down instead of up, making that the wrong thing (method history from the very first example). Therefore, I figure it would be easier to understand if the top and bottom counting math was the same, and only the lerps were different (instead of the counting being different and lerps being the same)

[indigo finch]

yea, intended. The differences seemed to be throwing you off

[fallen chasm]

eh... I'm more confused by the inside/outside transition -- I've swapped the 'ab' noodles to several configurations, but the behavior hasn't changed

it is /working/ though -- I just need to get the in-out transitions to behave

this matches yours, right?

[indigo finch]

that bit does. mind showing the whole code?

[fallen chasm]

hek

[indigo finch]

on player exit's 'set lerp counter' needs to be the same as onplayerenter

[fallen chasm]

I'm missing a nood

yep

wait

both 1?

[indigo finch]

as we are doing the same counting math for both

[fallen chasm]

well, both 0 based on your phrasing

gotcha

[indigo finch]

before we were counting downwards, so it had to be max value. now both are counting up, so they should be the same

[fallen chasm]

I also spotted a missing noodle from the countdown addition to the lerp counter

[indigo finch]

true

[fallen chasm]

woof... seems to work, so long as I don't immediately exit the room

walking back and forth through the door makes it snap

but letting it fully play seems fine since it's settles on the end/start values

[indigo finch]

you could add a bool tocheck if a transition is playing. if it is, timer = 1 - current time. would have to stop the other routine going though

[broken bear]

do you need SetLerpCounter on the enter/exit? you can have it set at 0 by default, it will count up through the math already, and countdown on an early exit will take the existing value and count down from that.

[grand temple]

You're making it more complicated than it needs to be. You don't have to directly control the exact time that it does the lerp. Instead, simply plug in the current value for A, the target value for B, and some low number like 0.05 for t. Then run that on update. Every frame, it will get 0.05 closer to the target, and it will smoothly change. Then you don't have to do any complicated delays or counters, literally just set the target value when you want it to change

[fallen chasm]

what are the chances... my old script worked, but since I was using '5' for the time... it was basically instant?

[indigo finch]

...

[grand temple]

Lerp only cares about 0 to 1

[fallen chasm]

I feel so dumb right now XD

of course... ... float isn't just a decimal number... it's like... 0-1 in decimals

ok, well... I have a backup of the previous one, lemme give it a test

[indigo finch]

your old script only called the funtion once. but yea, phasedragon is right in terms of the overcomplicated nature of my code

[fallen chasm]

I had this going before you shared your setup^

I was having trouble making the update and enter/exit triggers cooperate

and ... I think I understand why now

sendChange isn't doing anything

[grand temple]

It's not doing anything because you're not setting it to anything

You left the value blank

[fallen chasm]

yea... I though it was setting that bool

hmm... alrighty, added a const to set it, and it does fire once, and instantly

hmmmmmmmm using the immense knowledge you've

imparted, I am determined to figure this out

is that sound logic right there?

[grand temple]

You don't need state

Just a target value

[fallen chasm]

lemme give it a go

I'm missing something...

[indigo finch]

the script looks fine from what I can see. how is it failing?

[grand temple]

Transitionspeed is too low

If you're multiplying it with Delta time then it doesn't need to be low, it can be a regular number like 1 or 2

[fallen chasm]

I'm gonna go cry in a corner XD

yea... that solved it

works perfectly

oh wow... I think I've leveled up again...

now I can lerp things!

I appreciate y'all helpin' me figure this out

[indigo finch]

Hey Phasedragon, would it be worthwhile adding a bool like so to avoid it constantly changing the world settings? or is the performance cost negligible

[fallen chasm]

especially you @indigo finch -- we kinda went on a journey there XD

[indigo finch]

feel like i may have lead you more down a rabbit hole than a journey XD

[grand temple]

Yeah, that's worth doing

[fallen chasm]

yes, but if not for that, I would have never realized the mistake I'd made using sendchange instead of a const -- among other things.

-- I'll see about injecting that bool to avoid constant update checks

[grand temple]

I would use the onvaluechanged of TargetValue to enable is transitioning instead of having to do it manually anywhere that you change it

You can get that node by holding alt while dragging a variable into the graph. It's an event that will happen whenever the variable changes

[indigo finch]

like so? what's the advantages of doing it like this?

[grand temple]

Just easier to work with

[indigo finch]

fair enough. works for me

[grand temple]

You'll have to enable sendchange though

[indigo finch]

isn't that only if its global?

aka networked?

[grand temple]

No, sendchange has nothing to do with that

The only thing sendchange does is make it work with onvaluechanged

[indigo finch]

oh. that's an interesting quirk where you can change a value and it not fire the event literally called 'on value changed'. guess that would be useful if you had to reset some settings though

[fallen chasm]

I followed your example to add that to my messy noodles

doesn't seem to wanna run anymore

perhaps I missed something :/

oh I should switch density and color set

dang... not the cause

!!

sendChange!

double dang... that wasn't it either

but I'm assuming that's necessary for the event change node

[indigo finch]

I think your nodes have gotten messier... I'm a little unsure as to what goes where for some of them. I highly recommend duplicating some nodes for better readability. It makes troubleshooting easier for yourself too
That being said, as to why it isn't working I'm unsure. Step 1 of troubleshooting is going from the last knowing working point and building from there. You said you had it working without the bool right? Perhaps avoid doing the 'on target density change' node thing, or something. If literally nothing is happening when you go into the trigger, then it's almost guaranteed that the bool isn't changing. Do you get any console error messages of the script crashing?

[night viper]

On Udon. Is there a way to get the position of the vrchat´s UI cursor (arrow) while using a canvas? I am trying to create a drag and drop system for UI objects similar to those found on most mobile games. Like an inventory system where you can move items around a menu but using the vrchat raycast/pointer/cursor. Or will I need to create my own raycast?

[fallen chasm]

No errors in the console, but I figure you're right about the bool just not changing... It works when I disconnect those things, so I think tomorrow I might see about setting the is transitioning variable based on whether or not a trigger event has happened.

[indigo finch]

When you get to it, add a bunch of debug.log nodes throughout the code to find where things stop. then you know where it's not connecting

[tranquil acorn]

Thanks for the help, So you mean in this program get forward basically add a the number of velocity on blue arrow direction to player current velocity? But how do you change the number it added to current velocity? I try to plug in a new vector 3 node but it didn't work.

[indigo finch]

Vector3.forward is just a Vector3(0,0,1). You can just multiply the vector3.forward with a number to change it's power

The script in question:
gets the players velocity, adds a force to that velocity (being 0,0,1) and then reduces that velocity to be within a speed limit

[tranquil acorn]

Cool that explain it, thanks! Also, I found a force node, whats the different between these two? Force node manipulate object with certain amount of force and other use certain amount of acceleration?

[indigo finch]

sorry, what was the exact name of the node?

[tranquil acorn]

the node are under constant force

called set force

[indigo finch]

"Constant Force is a quick utility for adding constant forces to a Rigidbody. This works great for one shot objects like rockets, if you don’t want it to start with a large velocity but instead accelerate." apparently. personally never come across it before though

https://docs.unity3d.com/Manual/class-ConstantForce.html

to answer it a bit more completely, a constant force is a component in unity. you would have to add one in the inspector. As you can't add components to the player's avatars, this wasn't what you were after

[tranquil acorn]

oh, so vrc doesn't support this kind of manipulation on avatar?

I can still use it on world right?

[indigo finch]

the only player manipulation you can do is everything found in 'playerapi'. you could always get the player to hop into a station and move them around that way, but that's often not the most ideal way

[tranquil acorn]

make sense, thanks

[indigo finch]

np. glad I could help ^^

[mighty fjord]

@fallen chasm You should probably add a new variable for the lerps time, and adding TransitionSpeed * deltaTime to tha variable every update, then you can use that for the 't' on the lerp nodes

I believe that it might be stopping the transition prematurely as the lerps difference each frame gets incrementally smaller, which in turn might make the approximation node return true, preventing any further transition

So what's actually happening when you get the fogColor and use it as 'a' in the lerp instead is that you're not doing a linear transition anymore

Instead of doing that, you should also store the color the fog initially was when you change TargetDensity

[desert grove]

The position of the cursor is the camera. So yes, you can use physics Raycast use Get forward for the direction and assign a min max distance. After that its just about defining what you do when the raycast hit is true and your parameters/events are passed. see the "Udon Raycast" prefab at vrcprefabs for a working example Phasedragon created.

[night viper]

Oh Thank you! Will check that out!!

[hollow widget]

Did you know how to make button in udon script to delete this spawn object.

[desert grove]

A button would require you to get the objects (reference). A trigger zone would be easier (trash can setup). Either way the node is probably Destroy

[hollow widget]

Did you know how to script that trash. help me please.

[balmy solar]

How do I request a manual variable sync in UdonSharp?

[grand temple]

RequestSerialization();

[topaz jetty]

it doesn't register any video player events at all for some reason

[balmy solar]

Thanks! I thought it was under Networking so I was very confused when I couldn't find anything related under that namespace

[candid shoal]

Hello. So I'm having a big problem with synchronising an int over network. Basically I pick a random number and start the game for everyone. but the number is not being synced yet so I put the start event in OnDeserialization. The sync method is Continues but OnDeserialization is never called. ever... I don't know what to do...

public override void OnDeserialization()
{
    if (SYNC_MurdererID > -1)
    {
        GameStarted();
    }

    UpdateBoard();
}

public void StartGame()
{
    if (Networking.IsOwner(gameObject))
    {
        int murdererIndex = UnityEngine.Random.Range(0, _CountPlayers() - 1);
        SYNC_MurdererID = PlayerIDs[murdererIndex];

        GameStarted();
    }
}```

[grand temple]

After you change the variable you need to call RequestSerialization

[candid shoal]

Even on Continues?

[grand temple]

I don't know what you're asking, but any time you change a synced variable on a manual synced udonbehaviour, if you want other people to see it you need to call RequestSerialization

[candid shoal]

Like I mentioned, it's not manual

[grand temple]

oh, continuous sync?

no, you don't need to

If you're not getting OnDeserialization on continuous sync, then you're not receiving any synced data. This could be because you're alone in the instance, you're the owner of the object, or this object is instantiated so it is not able to be synced

[candid shoal]

I am the owner of the object. That's why I called the start method for me manually but everyone else in the instance is not getting synced.

[grand temple]

I would recommend adding debug logs to see what is actually happening. The first thing I would check is to make sure that GameStarted is even functioning correctly. It should be getting called, but maybe it's not working properly on the remote clients

[desert grove]

Not in graph. Still, nodes should be similar if fully exposed. Trashcan gets a collider flagged as trigger. Udon behavior gets attached. Add an OnTriggerEnter event. Use an if statement (Have no idea what that is called in graph), if the other.transform.gameobject's layer is pickup then "Destroy(other.gameObject);" You should be able to write it out based on your instantiation graph.

[balmy solar]

Having a weird issue where OnPickup and OnDrop wont get called unless my Udon object is a child of a specific gameobject. It doesn't matter what order the gameobjects are in or what the script is, if it's not on this specific gameobject it wont run those methods. The gameobject has no scripts of any kind, and at no point do I do anything to that parent

Also tried creating new objects and parenting them to that, but still doesn't work

Btw I mean setting the parent in Unity, not via Udon code

[hollow widget]

thank you very much

[balmy solar]

I have no idea what's going on. I tried restarting Unity and my PC, I tried creating entirely fresh scripts, it will not work unless it's a child of that specific gameobject. This is clearly a bug for either UdonSharp or the VRCsdk but I'm too exhausted to deal with it today. I just want to be done and for my asset to work..

Tomorrow I'll try reinstalling VRCSDK and UdonSharp and if that doesn't work I'll file a report

[desert grove]

That doesn't sound like a vrc+addon issue at all. The only participant in this issue that would care about what is parented to what is Unity. Dev engines wig out all the time. Do the ticket thing, but I'd encourage you to check the Unity discord as well.

[balmy solar]

I don't think it's a Unity issue. the logs show that VRC Pickup is being called and that "Pickup Object" and "Drop Object" are being handled correctly

(the line below is from my OnPickup method, the next three lines show that VRC Pickup is working)

(these three lines show that VRC Pickup is working, but the output from OnPickup isn't here)

This is what my OnPickup looks like. In the output above, two objects share the same script but are under different objects
it does not matter which object is under which parent, or if both are together: if they're not a child of a specific gameobject, OnPickup is not called, even though the log says that pick and drop were called in the VRC Pickup script

public override void OnPickup()
{
    isHolding = true;
    Debug.Log("Pickup is working");
}

[desert grove]

So what is this specific gameObject they want parented to?

[balmy solar]

Just a random empty gameobject with no components at 0,0,0. I can change the name and it still works. There's seriously nothing special about it

[desert grove]

did you try deleting it? just throw sht out there

[balmy solar]

I'm kinda scared to, then I won't have anything to show when I submit my bug report

[weary scroll]

Hey so I don’t want to go around and click “see avatar” on everyone

What are the settings to change that

[balmy solar]

@weary scroll That isn't an udon question, ask in #vrchat-general-1

[balmy solar]

Any idea why this line isn't working? It throws a nullreferenceexceprion from Update()

Here's the referenced script

[mighty fjord]

Which line is it that's throwing a nullref?

[mighty fjord]

Could deckController be null?

[dark blade]

im having an error where it says its missing ascript of vrc. its cs0234 and cs0236 and i put the newest vrcsdk3 in FIRST

[balmy solar]

in unity it isnt null and it doesnt throw an error on getvarable or ids[i] = id only on the setvarable

sorry for spelling im in vr

[fallen chasm]

quick update for ya -- I kept the 'isTransitioning' bool, but adjusted it to turn on with the triggers and off at the end of the update. I also added an event start to set the first fog color. My noodles are still a bit tangled up, but everything is working great. Thanks again.

[indigo finch]

Sweet! glad it working

[valid totem]

Is there a way to prevent sound from passing through an object?

not sure if that would be an udon thing or not

[fallen chasm]

are blendshapes on gameobjects exposed to udon yet?

neeevermind -- I found it

[valid totem]

Could anyone share how can I access the class of an udonbehavior from GetComponent? I think it was linked earlier before the last bot raid and was deleted when the mods cleaned up

[eager olive]

VRChat doesn't support this natively, but there's some prefabs attempting to do audio occlusion. https://github.com/Guribo/BetterAudio

Replacing the current audio enginge (ONSP) with steam audio would also enable us to do that. Here's the relevant canny: https://feedback.vrchat.com/feature-requests/p/replace-onsp-with-steam-audio

[wind atlas]

Is the commented out line not working? That's odd, since you already call GetProgramVariable right before.
What's the error in the console?

[balmy solar]

Nullreferenceexception, but it's not giving me any info about what exactly the problem is

[wind atlas]

Oh, is it a unity error?

Then it shouldn't have anything to do with udon.

[mighty fjord]

Do you not get an U# log in Unity after the script crashes ingame?

[balmy solar]

In Unity? No? I've never gotten output in Unity, I have to dig through the logs

[mighty fjord]

It's trying to get a transform from a null GameObject somewhere

[grand temple]

go to edit > project settings > udonsharp then enable these options

[balmy solar]

Then why does it happen on this line (the commented out one)

[grand temple]

then in the log, you'll get an extra error specifically made by udonsharp, which will point to the exact point in your code that the error happened

[balmy solar]

That's very helpful!

I'll try it later when I'm working

[valid totem]

In case someone tries to ctrl+f this later, what I needed to do was
var behaviour = (UdonBehaviour)other.gameObject.GetComponent(typeof(UdonBehaviour));
then I could access the public variables using
(T)behaviour.GetProgramVariable("TheNameOfTheVariable")

[junior lava]

Can't you just do

other.gameObject.GetComponent<T>()

And then use that to access all its publicly accessible variables and methods?

[valid totem]

from the readme at https://github.com/MerlinVR/UdonSharp/blob/master/README.md

If you need to call GetComponent<UdonBehaviour>() you will need to use (UdonBehaviour)GetComponent(typeof(UdonBehaviour)) at the moment since the generic get component is not exposed for UdonBehaviour yet. GetComponent() works for other Unity component types though.

You can do that with unity components

but VRC components need to have their type casted

[junior lava]

Does it work for child UdonBehaviours? I've never had issues calling GetComponent<ChildUdonBehaviour>().

[valid totem]

ahh I don't know what child udonbehaviours are yet, so I don't know

[junior lava]

Like, when you make a new U# script and it inherits UdonBehaviour.

[valid totem]

like when you serializefield another udon class?

you can access it in that way?

uhm that's pretty cool, I haven't tried that

[junior lava]

Forget what I'm saying, maybe I'm wrong.

[wind atlas]

What are you trying to do? Just out of curiosity.

I understand you want to save an instance of UdonBehavior.

Does it have to be interchangeable, or could you just save the implementation itself?

[junior lava]

I think puppet is saying what I'm saying. Are you trying to fetch a particular UdonBehaviour or any generic UdonBehaviour?

[wind atlas]

It does sound like they need a generic one. I'm more so curious what they are working on.

[valid totem]

I needed mine to be interchangeable so I could reduce coupling between a player held object and a pickupable that needs to work with any of the player objects

I wasn't trying to use child udonbehaviours, that's a new one for me

[junior lava]

Ok cool. Thanks for lettin me know. 🙂

A child is anything that inherits from UdonBehaviour,

So like

class Hitbox : UdonBehaviour

[valid totem]

oohh

dang so you can pull that directly?

[junior lava]

I believe so, I believe in that case you can just call.

GetComponent<Hitbox>()

In that case.

[valid totem]

niice

[junior lava]

It's never given me issues at least.

[valid totem]

I'm going to give that a try, thanks Wetalo

[wind atlas]

Yeah, that means you don't actually need polymorphism? You would get a generic base class in the case where you have SwordPickup, MagicPickup, KeyPickup classes that all have a specific method exposed. Like "Explode()", which you could call regardless of which one of the three it is.

[brave sage]

is there any vr chat support because I try calling the customer support and they had no vr chat support

[wind atlas]

This channel is about udon, so unless your issue is about that, this is the wrong channel for it.

[brave sage]

nnot sure what udon is sorry

[wind atlas]

It's for making worlds in vrchat.

[brave sage]

ohhh ok sorry

[valid totem]

This worked great thank you

[junior lava]

I actually don't remember, does udon throw an error and asks you to change how you call it? I don't recall and I'm not at my pc right now.

[valid totem]

nope it was exactly what I was originally looking for @junior lava

instead of having to do all that casting and them using those string calls for methods and variables I could access them in a way that is more friendly (ie intellisense 🙂 )

reduced 3 lines of code to 1

The next thing I'm trying to do is keep an object's position tied to another objects position without changing the parent...

Seems like when I make an object a child of another object it immediately becomes stretched and deformed, so I'm looking to get the location of an object relative to the world and set the other objects location to that with Update() so long as a trigger is active

unless anyone knows a better way please 😄

but this may be the way https://answers.unity.com/questions/1583375/how-to-prevent-child-deformation-on-rotate.html

[junior lava]

To fix the stretching issue, ensure the parent's scale is 1,1,1

Classic Unity problem.

[valid totem]

does it matter if the child object is 1,1,1?

bout to find out heh

[wind atlas]

Parenting to keep the position is the easiest way. Just make sure the parent is "clean". If it's a mesh, create a separate GameObject and parent the mesh to it. This way, you can deform the mesh while the parent stays at 1,1,1 scale and you can attach other objects to that parent without the deformation issue you are experiencing.

[wind atlas]

There are also Constraint components that solve this issue without parenting.

[valid totem]

oh nice

[junior lava]

What Constraint allows that?

[wind atlas]

"keep an object's position tied to another objects position" can be solve by this:
https://docs.unity3d.com/Manual/class-PositionConstraint.html

[junior lava]

Oh damn! I've never heard of this and I've been working with Unity for four years. Thank you! 😄

[wind atlas]

Pretty sure people who make avatars use it sometimes, as it doesn't require scripts AND it can be controller by animators.

[faint fiber]

Hey, I wanted to make a system where upon loading into the world, a random audio from a list starts playing

I've done some digging but I can't seem to figure out how to execute that random chance sort of thing

Anyone know how to get this sort of thing to work with udon?

[indigo finch]

Have an array of sounds, and do a array.get node. That get node will ask for an int, to which you can create a random.Range node (set to int) and set its values from zero to array length.

[candid shoal]

Hi everyone. Quick question, can any object teleport the player or does it have to be triggered by the owner or the master?

[grand temple]

who you can teleport doesn't have anything to do with ownership. What matters is that you can only teleport the local player. So if I click an interact, I can't get your playerapi and tell that playerapi to teleport. I have to send something over the network, which could be synced variables or a network event, and then when you receive it you would tell your own local playerapi to teleport

[faint fiber]

How would I create an array of all the sounds?

[faint fiber]

Oh wait no I think I understand

[blissful vapor]

how do you make a questing system (Challenges, Missions) in udon?

Ive looked everywhere on youtube and forums and it's all about 'How to publish to quest"

[indigo finch]

Do you have a world your trying to base this off? Udon is still relatively new in the scheme of things, so even if someone has done a questing system, it's unlikely there'll will be any tutorials on it online
I would recommend looking at tutorials for standard unity, and porting it over to udon (as udon is basically a partially restricted C#), though it will take an amount of work.
If your planning on using the default udon graph instead of udon#, you might want to see if someone has made a questing system in Bolt, unity's node based C# scripting tool (like udon graph)

[blissful vapor]

yea

but aight

thanks

[desert grove]

Basic setup single gather quest:
Attach a script to a gameobject. That script contains a few variables:
Bool QuestID; Int IDGatherCount;

Each object that is to be gathered has another script:
Bool Awarded; OnPickup if Awarded is false? Get the script with the variables and add 1 to IDGatherCount. Set Awarded to true. On Drop, set inactive.

Quest Giver:
Bool IsComplete; Get variable script; Int MyGatherReq; if QuestID is false? Display canvas. If you click ok for the ui you make, set QuestID to true. Else, if IDGatherCount == MyGatherReq IsComplete is true. Give Reward.

Use Udonchips for your reward system, although its real easy to script that as well. The above isnt a script, just a quick summary of a gather quest. Should be very easy to implement with a tiny bit of homeework on Udon.

[broken bear]

Doing an interact where I want everyone to run a fucntion, the function control toggles and animators. It works locally fine, but remote players are not running the function. UB is set to manual

[broken bear]

oh wait I need a Get Gameobject to feed into (obj) on setowner - edit: nope still didn't solve it It's not even calling OnDeserialization

[broken bear]

and it turned out that this interact object was disabled in the scene at upload and subsequently turned on. if it's enabled in the scene then it works. That old bug, I wish I knew why some udon behaviors don't work if they are disabled in the scene on upload

[hushed gazelle]

You're doing that wrong; You just send a custom network event.

[faint fiber]

I got it to work really well actually, thank you so much

Is there a way to make it local only?

Sorry, I'm a noob when it comes to coding anything lmao

[junior lava]

By default it should be local only.

[faint fiber]

The issue is that new music starts on both sides

every time a new player joins, the players present in-game get more overlapping music

is it possible to make it so only the joining player hears the music?

[night viper]

Would help if you show your setup.

[indigo finch]

The problem is that the 'OnPlayerJoined' plays whenever a player joins, for everyone. Since you only want it to play for the player that just joined, you'll need to do a check to see if you, the local player, were the one that just joined.
To do so, grab the playerApi on the 'onPlayerJoined' node, and plug it into an 'playerApi.isLocal' node. You'll then get a bool value that you can plug into a 'branch' node. Then, anything that is connected after 'true' will only run for the player that just joined

[waxen niche]

Can i make it where on my avatar i have a part that another user can pick me up

[indigo finch]

Given you posted this in the udon channel, I'm assuming you want this to be something for your world instead of a just your avatar right? If so, you should check out Yeet-O-Matic by Hannah "FairlySadPanda" Dawson found on VRCprefabs database. It seems like it would be about what your after.
If you wanted to do this as part of your avatar, you should ask in one of the avatar3.0 channels, as udon is for worlds only and works rather differently for interactions

[waxen niche]

Alright thanks, to many channels

[candid shoal]

Is there a proper way to do a look-at-camera object? Like a local GUI?

I'm talking about something like an indicator or alert that shows up only on player's camera.

[fiery yoke]

Define proper lol

[candid shoal]

Is there a defined way to do it or do I have to come up with my own way?

It’s not the easiest task

[fiery yoke]

VRChat does not state an "official " way, but I think the best way is to use Unities inbuilt system. You can set a Canvas to be in Camera Space. I'm not entirely sure how to do it myself, but I think you also need to add the VRCUiShape script to the canvas object, as it automatically sets the reference Camera.

[desert grove]

The canvas in its default state works for a gui, adding the vrc shape allows for interaction, but a gui doesnt move, it is always centered on your screen unless you make something in your hand. Way different setup. So given that the gui is stationary, it is impossible to interact with it unless you bring up the menu which will then block most of your screen or all of it in full menu view. So really, gui's are best used as just overlays to relay player variable details (points, health, ammo etc)

[fiery yoke]

I think what they wanted is a HUD (Heads Up Display). GUI (Graphical User Interface) can mean pretty much anything. And yes adding the VRCUiShape adds the ability to interact with it. However it does so by setting the reference Camera to the players Camera. This fact can also be used for the fact that a canvas can render directly in Camera Space when a reference Camera is set. It can then also no longer be interacted with AFAIK.

[desert grove]

Yeah that's what I was thinking too. Hud just being visible, GUI being something you expect to interact with. Figured ied throw out the issue with full screen HUD like GUI's in VRC. Now if they give us a free-look with interaction* option that would be great and make GUI's like that possible.

[foggy knoll]

If I test scripts that are not on the supported list would I get in trouble? Is that against TOS or guidelines? If these scripts work and improve quality of life for players would I be allowed to share and show people how to make it work? I ask because I have been playing with Vive's Facial tracking SDK. I haven't uploaded anything to vrc with it, because I rather ask for permission than forgiveness. Thank you in advance.

[grand temple]

you won't be able to

it will just not work

[foggy knoll]

Can you elaborate?

[grand temple]

.cs scripts can't be uploaded

along with anything else that resembles a script

[foggy knoll]

Isn't dynamic bones a .cs file?

[grand temple]

dynamic bones is a whitelisted script that is included in the application, not uploaded with the avatar

the settings are uploaded with the avatar but not the script itself

[foggy knoll]

So another question. When I upload a avatar for testing. Is that uploaded to servers or is that local to me on my own pc?

[grand temple]

local test avatars are local to your pc. Uploading avatars goes to the server

[foggy knoll]

Also to my original question. Lets say I could upload it as a test avatar despite it not being white listed. Would I get in trouble?

[grand temple]

if you can somehow bypass that security, then you won't be banned automatically. If you start abusing it and someone reports you, you could get banned

if you do discover something like that, you should report it to security through private channels. Doing so will ensure that you won't get in trouble

[foggy knoll]

No I would share it with the devs asking to have it whitelisted.

[grand temple]

that's just not how any of this works

[foggy knoll]

?

[grand temple]

if you want to ask for a script to be whitelisted, sure, go to the canny

but that's not the same as a script that is able to bypass the security

I assure you that any random script from some vive SDK is not going to be able to bypass security

[elder peak]

to clear up potential misunderstanding, the whitelist is not a list of "this is proven to work in vrc" but a list of allowed assets

[grand temple]

At this point it's been so long without an incident that if it was possible to upload an avatar with a full blown script, somebody would have done it a long time ago

[dapper lion]

its baked in assets. nothing scripted is actually uploaded

it would almost impossoble

[primal dew]

when does dynamic bones for quest come out?

[elder peak]

it likely won't as vrchat is working on their own solution, if they will add that to quest, has not been stated as far as i know

[candid shoal]

I'm still having this issue. Would you be kind enough to look at a snippet of my code? This only works if the person who killed the player, is the instance owner. I know you said it has nothing to do with ownership but something's not working and I don't know what 😦

    {
        if (SYNC_GameStarted)
        {
            if (SYNC_KilledPlayerID > -1)
            {
                if (Networking.LocalPlayer.playerId == SYNC_KilledPlayerID && !_isDead)
                {
                    _isDead = true;
                    SYNC_KilledPlayerID = -1;
                    SendCustomEventDelayedSeconds("RespawnLocalPlayer", 0.3f);
                }
            }
        }
    }```
```public void RespawnLocalPlayer()
    {
        GameObject spawn = GameObject.Find("VRCWorld");
        Networking.LocalPlayer.TeleportTo(spawn.transform.position, spawn.transform.rotation);
    }```

[grand temple]

you need to take ownership before you set synced variables

[candid shoal]

Oh, so only the owner can sync?

[grand temple]

yes

[pliant tiger]

Wanted to ask if there is a way other then making it a local event to where doors will stay open if someone is still in the trigger area? I have this as my setup right now but if two people are on the tigger and one leaves, it closes the door on the other person till they leave it and go back in to the trigger area.

Should I add a stay with the animation remaining open?

[west mural]

count how many people are in the trigger

OnPlayerTriggerEnter: count + 1, set open

OnPlayerTriggerExit: count - 1, if count == 0 set close

[pliant tiger]

Thanks

hello, i have a question about udon: is it possible to force a player to jump forward? like stepping on jump pads

[desert grove]

Jump is, see player mods. Not sure about direction. Absolutely possible using station hacks.

[visual elm]

player mods?

[desert grove]

player mods are what permit jumping, sets run speeds that stuff.

[visual elm]

ah, i see

[desert grove]

if you want to see some cool prefabs and adopt some of the udon like jump pads look at one of our vrc jams. There is a download link on the page. You will want to load it as a new project, and if you want to adopt some of the prefabs just open up the jam project along side your current project. https://itch.io/jam/vrchat-obstacle-jam

[mellow hedge]

Has anyone noticed that multiple local clients to test networked behaviors doesn't work anymore? I can launch two clients like usual through the SDK but the clients cannot see each other in the world.

[desert grove]

Interesting, tbf network testing never did work. Both clients were the same user so you wern't testing networked events locally.

[mellow hedge]

It certainly worked better than it does right now because I could see the other local user(s) and verify their interactions with the world :(

[desert grove]

You have a point 😉 post a canny

so im working with Udonaudio link in a world im making but the audio link only wants to work with Audio source in the audiolinkimput area and no any video source how do i fix this its driving me insane

[molten dune]

Howdy, I'm looking for a simple jukebox for my 3.0 world. Something insanely simple for someone with a small brain.

[desert grove]

not sure if there is a free one but this is less than $3 https://booth.pm/ja/items/2543529

[molten dune]

Is it like a prefab that I can just import?

If so then its worth it

[wanton oxide]

https://github.com/Varneon/UdonEssentials

You probably wanna use the music player in here

its very clean

[molten dune]

Are there tutorials on how to use these things?

i am very slow

[wanton oxide]

read the page

[desert grove]

That thumbnail looks sick as fk, great photoshop skills.

[wanton oxide]

you just install udonsharp and drop the prefab in there

iirc it has a custom inspector to make it easier to add stuff

[desert grove]

sounds like the booth one but free trumps all 😉 great suggestion BocuD

Alrighty I'll try it out

[wanton oxide]

its a fair bit better than the booth one probably

[molten dune]

Thank you so much

[mellow hedge]

I have posted the "fix" AKA things suddenly just work now in a comment on this canny

[balmy solar]

How do I call an method from another script and pass it a variable in UdonSharp?

public void TestEvent(int num)

[wind atlas]

You can do udon.TestEvent(yourNum), or is that not an option for you?

[balmy solar]

is 'udon' a UdonBehaviour?

[wind atlas]

public OtherUdonScript udon;
void Start()
{
    udon.TestEvent(yourNum)
}

Kinda like this;

Yes, it is.

[wind atlas]

I'm not sure what I'm looking at. VRC_Interactable is a VRC type? (never used it before) and not your custom UdonBehavior type?

[balmy solar]

Oh wait, can I call one of my scripts directly? So far I've been doing something like this...

[wind atlas]

That's what I meant by "OtherUdonScript" above. So if you have script that's called "DeckController" then just use it directly instead of "UdonBheaviour".

[balmy solar]

The tutorial I watched specifically said I couldn't do that, so I've been pulling out my hair trying to find various ways around it x.x

[wind atlas]

That's odd 🤔 Maybe it was about udon and not udonsharp?

[balmy solar]

No, it was an UdonSharp code tutorial, but it might've been outdated

[wind atlas]

Could definitely be, I haven't followed it for that long.

[balmy solar]

Welp.. time to rewrite my entire codebase...

[wind atlas]

It's the programmer's fate, ending up with way less code at the end than you wrote at the beginning :P

[balmy solar]

Between this and me learning I can get proper exception traces in Unity this has become so much easier

[mellow hedge]

Reimajo has a really good example about this. But yes, instantiate an UdonSharpBehavior script2 as input to script1, and inside script1 use script2.SetProgramVariable(name, value), script2.SendCustomEvent(eventName), and you should be good to go!

[balmy solar]

This is literally what he just said I didn't have to do. I can just call my scripts directly and then call methods and variables directly without needing to use SetProgramVariable and GetProgramVariable

[balmy solar]

Wanted to thank you again for this, it's helping me a lot

[primal dew]

When does moveable hair/ears/dress/etc come out?

for quest

[balmy solar]

This isn't an Udon question

[desert swallow]

Would anyone be able to show me how to setup a basic udon script for turning multiple colliders on an object on/off with a singular button, am brand new to udon and cannot find a good video on youtube to learn from

(I could also probably figure stuff out myself from just looking at an already existing one)

[balmy solar]

You can either toggle isKinematic on the RigidBody, or make a list of type Collider and add all your colliders to it and then loop through them and run setActive false

I can't give an Udon Graph example, but in UdonSharp it would be something like this:

public Collider[] colliders;

public void ToggleColliders(bool value) 
{
    foreach(Collider collider in colliders)
    {
        collider.setActive(value);
    }
}

[desert swallow]

hmm am not quite understanding this

wait I got it to work

Somehow this Just works to enable/dissable both colliders at a button press

[balmy solar]

Yeah sorry, I don't work with Udon Graph so I couldn't give an example

I'm surprised someone else didn't jump in tho

[desert swallow]

Ye, Udon Graph I would assume is the easiest to learn with given 0 prior Udon knowledge with also having 0 coding knowledge in general so I'm using it

[wind atlas]

Didn't you figure it out though? Chaining a few Set enable is a valid way to do it.

[desert swallow]

the GUI is atleast very simple to look at (and I managed to figure the above out by partially copying a mirror tutorial and changing some things)

[balmy solar]

If the only thing I'm syncing is a list of 1-2 digit ints less than 100 long, is that too much to put on a continuous update?

Having trouble getting manual syncing to work and wanted to know if that would ruin the ping of everyone in the world

[paper plinth]

heyyy
can someone please tell me what nodes to use
when I want to make a line from 1 position in world space to another
and determine if the line hits anything

[fiery yoke]

The keyword here is "Raycast". Try to find a tutorial about Raycasting for Unity first and get the general idea of it.

[paper plinth]

yee thanks

I have a line renderer set up to make a nice green line
but if someone blocks it I want it to turn red
and I don't think I can do that with just the line renderer

[blissful vapor]

So I've been trying to make an udon UI based NPC dialogue and Quests system, but I'm not sure how to do it, if you guys have tips, guides, or advice, please reply or dm me

[paper plinth]

Thx Helpful Helper

[blissful vapor]

Still looking for advice

[paper plinth]

you just kinda do it

to be honest

I'd probably put the individual quests as their own udon programs and call them

dialogue and quests are just displayign information and ordering events which is easy

the biggest issue is an inventory system

I wouldn't spend too much time on NPCs either

just display text when you're close enough

I got stuck on the mechanics of harvesting using a harvesting tool

I even made an airship

[grand temple]

yeah, that's such a huge project that it's a bit unreasonable to ask for advice on everything all at once. If you want to make something like that you need to design the architecture yourself. If you're confused about specific things you can totally ask for help, but you should know how everything goes together

[paper plinth]

first step is to plan it

[grand temple]

and if you don't even know where to begin, you should probably start with something smaller 😅

[paper plinth]

probably you could build it in stages if you wanted to learn as you go

like start with terrain and lighting, add plants, make a basic map, put in buildings and props

that's going to take you a month to learn and have it not look like a pile of trash

[blissful vapor]

The thing is I've made the map, and the NPC I just was trying to see how to make the system

sorry, I shouldve Explained better-

[paper plinth]

it's like othello
a minute to learn, a lifetime to master
u must begin with the first thing you want to do
and then make it happen
use nodes

specific questions will come up, just ask them here

[blissful vapor]

Thanks

[paper plinth]

you'll be smashing your head into a wall with the nodegraph for like two weeks don't worry

[blissful vapor]

ok

[faint fiber]

This worked perfectly, thank you so much for your help man

[faint fiber]

Hey, so I downloaded this package and then building my world wouldn’t work

now last time this happened, I just deleted all the files installed by the package and it fixed, but this time it didn’t

the sdk control panel is just straight up gone

don’t know what to do here, just praying I didn’t just destroy everything

[desert grove]

That's not really an udon issue, more a #world-development one. But check your console for errors. Chances are you have a nice Standard Assets folder now that needs removed but feel free to post your error list screenshot in #world-development

[faint fiber]

Alright I’ll post more info there

[blissful vapor]

What action do I use to change components in a gameobject?

as in, what event

I'm trying to change a sprite

or image

and I also need to know what action i use to change text

[desert grove]

https://docs.unity3d.com/2018.1/Documentation/ScriptReference/UI.Image-sprite.html
https://docs.unity3d.com/2017.3/Documentation/ScriptReference/UI.Text-text.html
these can be translated into Udon or UdonSharp

https://docs.unity3d.com + https://docs.vrchat.com/docs/udon-node-graph is your bread and butter

[blissful vapor]

Thanks

[tranquil acorn]

So eh, I having a trouble with worlds, but im not sure if its a udon one. I want players in world move alone with a animated platform, how do I achieve that? I saw many games have this kind of transportation method, and I just went to Vket2021 Avatar Carousel and found they have the same thing on the Carousel itself, kinda feels like the physicals in side this area are isolated with the outside.

I can't find anything online so I thought I just place a animated platform under my avatar see if it works, I didn't just like what I expected.

[wind atlas]

Easiest way would be to put the player into a seat.

[tranquil acorn]

I know can just place a seat but I want player to walk around during transport

[wind atlas]

Otherwise you can cast a Raycast downwards and then move the player with the object they are standing on.

[tranquil acorn]

whats a raycast?

not an expert so there are many concept in unity I dont know

[wind atlas]

I don't have time right now to explain everything. You could look for unity tutorials, they should work very similar to Udon.

Maybe this will help?

https://www.youtube.com/watch?v=rO19dA2jksk

[tranquil acorn]

oh, thanks bro

[wind atlas]

Also look up VRCPlayerAPI to see what you can do with the player.

[tranquil acorn]

Gotya, thanks for the help.

[grand temple]

That's a pretty advanced topic, and requires manipulating the VRC player in unorthodox ways. The unity tutorial isn't going to help much because that will assume you have complete control over the player controller, which is not the case here

[tranquil acorn]

oh

[grand temple]

just go with a station

[tranquil acorn]

ok, that make sense.

[tawny geyser]

Sounds like you want this: https://github.com/Superbstingray/UdonPlayerPlatformHook

[dreamy gorge]

does VRC_Pickup still work or do I have to use udon ?

[desert grove]

Of course it still works. You can find more components at https://docs.vrchat.com/docs/ anything marked sdk2 only or depreciated you avoid.

[vagrant coral]

Just had the weirdest thing happen in my project, all floats in all udon behaviors that had a decimal lost the decimal. So a 2.3 became 23 and so on. anyone else had this happen and know what causes it? 😄

[neat flicker]

Audio reverb filter is applied to my main camera, but player's voices won't echo. Only UI does. Any way to fix this?

[tranquil acorn]

OMG, thats exactly what I looking for, thank you so much bro.

[valid totem]

Is there a way via udon or otherwise to make colliders only work with specific objects, so that a player could pass through but an object could not?

[tawny geyser]

Haven't tried it, but Unity layers probably.

@valid totem Found it, go to Edit -> Project Settings -> Physics and you can adjust the Layer Collision Matrix at the bottom there.

[valid totem]

Pokeyi thank you again

[tawny geyser]

How flexible VRC SDK is with that I'm not sure.

[valid totem]

I hear that if we can do it natively or with udon we should choose natively heh

btw the thing that I've been asking for help a lot over the past week is on github now

https://github.com/pyralix/VRC-Skee-Ball

thank you for your help with that @tawny geyser, you had offered a lot of assistance to me

[tawny geyser]

Happy to help, and I'll check it out!

[molten dune]

Is there anyway I could get some 1 on 1 help with this audio player package I got? It's from udon essentals, and honestly I just can't find a button that it says I need to click :/ I think an extra set of eyes might help me

[wispy atlas]

If attaching an Audio Reverb Filter component to the main camera didn't work, create a new empty gameobject and attach an Audio Listener and Audio Reverb Filter component to that new empty gameobject

[hushed gazelle]

I know there's events for when a player interacts with a collider trigger (ie; enters/stays/exits it), but is there a way to actively check if there are players in the trigger space? (eg; Player leaves, check if other players are still in that space)

[valid totem]

I think the way to do this is during the OnTriggerStay event which is called every frame I believe

you will get a gameobject in that event each time that you can apply an if statement to

you could also add players to an array and remove them when they leave

then you wouldn't be performing logic on each frame

[hushed gazelle]

Yeah, I figured I'd just add an int to count players entering and exiting or something along those lines if there wasn't anything else. Just wanted to check if there was a clean way to poll the collider itself and have it return (for example) "There are 3 players inside this space".

[valid totem]

I'm a noob but I don't think so as it's like a snapshot in time and each frame is a snapshot

so you get a check each frame for whatever was inside the trigger bounds when that frame hit

again, that may be wrong.

[minor garden]

Would someone happen to know how to communicate arbitrary data from a Player that is not the GameObject Owner?

[valid totem]

Are you using U#?

[minor garden]

ye

[valid totem]

you don't get callbacks but you can send parameters with your methods

so if you can get the instance of the udonbehaviour you want the player to send data to you can do so by making the method take parameters and using them

[minor garden]

Is that something different from SendCustomNetworkEvent?

[valid totem]

I don't know how you might get data from them without them interacting with some other udonbehaviour though

well, to be clear I don't know how to send data with the SendCustomNetworkEvent method... But, if you get the class in U# and call the method directly you can send whatever data you'd like

[minor garden]

yes, but that only effects it locally.

[valid totem]

so you would still need to sync that data with everyone else who is not the owner in some way

and the owner of the object with the udonbehaviour would get it regardless if it was syncd to a variable or not

[minor garden]

yeah, and that's where I'm hitting a road block.
I tried a work-around where the player becomes the Object Owner, then sets the data, but I'm hitting a race condition where sometimes the ownership negotiation happens after the data is set, resulting in the Serialization to fail and be overwritten

[valid totem]

I wouldn't change the owner, when you send something to that specific udonbehaviour instance on a method that's public let the owner stay the owner and use them as the message bus to share that published data with the other player subscribers

[minor garden]

But I'm pretty sure it doesn't sync with the owner on a method call. All those changes stay local to the Player that called the method.

[valid totem]

What about when you use a sendcustomnetworkevent to the owner?

In that case you can access the owner's udonbehaviour instance

[minor garden]

sendcustomnetworkevent only fires a method on the owner's instance, it doesn't carry any data other than the method name

[valid totem]

I see what you mean, my bad

Maybe this is a case where SetProgramVariable comes into play

Looks like you could get a specific udonbehaviour and get/set a public variable in it. I have not tried that myself

[tawny geyser]

One of these might help but I don't think there are any simple built-in ways to do that properly yet. https://github.com/FairlySadPanda/UdonStringEvents or https://github.com/Reimajo/HorribleUdonNetworkingCodeGenerator

[minor garden]

I like the look of UdonStringEvents.

It'll be a work-around on top of a work-around on top of several other work-arounds... but it will work

[quartz meadow]

I don't think this channel can help you with that, this is for VRC SDK programming

[chilly viper]

Oh okay

is there a channel that can help me with that?

[wind wedge]

Is there an element in UDON where I can Get data on on the Player camera, Almost like how Mirrors work? (Very new to udon)

Or how do I get a Camera to locally follow a user (Preferably on their Avatar camera)

[grand temple]

You can't access the camera directly, but you can do playerapi GetTrackingData and plug in Networking.LocalPlayer. If you select head, that's the same position and rotation as the camera

[wind wedge]

THANKS!

[wind wedge]

Would this work?

[grand temple]

yep

[wind wedge]

Im not sure how to actually put it on the camera though

[grand temple]

oh wait not exactly

that puts it on the bone, which isn't always the camera

you want trackingdata

[wind wedge]

How would I translate those value into a Vector 3 and a Quaternion though ?

[grand temple]

trackingdata get position and trackingdata get rotation

[grand temple]

yep

you can reuse the same trackingdata though

[wind wedge]

😮

thanks, now i just have to figure out how to add those values to the caamera

wait, if i turn the "CameraToPlayer" Variable to My Camera in the main Hierarchy by dragging it into the Graph, would that work?

[grand temple]

of course, you can target anything you want

but that camera would just be following the player's camera, it wouldn't be the same thing

[wind wedge]

hmm

[grand temple]

what are you trying to accomplish?

[wind wedge]

Im trying to get a Camera to render out onto a plane what the User sees

so i though if i cant get data on the actual player camera, i could put a camera on their position and use that secondary camera

[grand temple]

yeah you can do that

you would want to create a render texture, and assign that to the camera

then give that render texture to a material

[wind wedge]

Yup, I was working on that but then i realized i didnt have a a camera so i tried working with udon

Thank you so much!

This is what i ended with Btw

[exotic river]

Is there any way I can make a special nametag go above specific peoples heads in my world?

[wind atlas]

Iterate through all players in the instance, get the head position for each one like you see in the comments above and then use that position on a world space canvas.

[wind wedge]

How do i get the Difference of two vector3 in Udon Graphs

https://tenor.com/view/cute-fingers-gif-20081440

[wind atlas]

Are you looking for the distance? There is a method for that.

[wind atlas]

If you mean the vector between two points, then you just subtract them.

[wind wedge]

i went to "Math" but there wasnt a subtraction option

like i cant find a subtraction node

op

o

i found it

[wind atlas]

Yeah, stuff like that is why I use U#. Not only is it annoying to find basic operations, but they also become very confusing to read.

[wind wedge]

This is my firs time working with Udon, im learning how its all layed out

[wind atlas]

If you have coding experience, make sure to check out U#. It's very similar to C# sharp, just very limited.

[wind wedge]

70% of my time on graphs is making it look neat though lol

[wind wedge]

i dont have much experience, sadly, it would help me so much if i did, but im getting by it seems

[desert swallow]

So I've got this little setup here to play a sound and make some particles when using a held object, but what do I add to sync it so other people hear the sound/see the particles when somebody else uses the object

[grand temple]

It's Vector3 subtraction

[wind atlas]

OnPickupUseUp -> SendCustomNetworkEvent instead of what you do now

[wind wedge]

mhmm. pulled out the nub from the node then searched for subtraction, i didn't know i could do that

[wind atlas]

The play nodes happen in your custom event.

[desert swallow]

So like this?

[wind atlas]

Disconnect the play nodes. Create a new event and connect the play nodes to that.

Then SendCustomEvent calls that event.

[desert swallow]

How do I create a new event for them

[wind atlas]

Good question 🤔

Let me check udon graph out real quick.

[wind atlas]

Type "event custom"

[desert swallow]

alright, got a new box for that

but not sure what to do with it

ah wait a minute I might see how to do this

[desert swallow]

Ye was about to try that, so from my understanding plug everything else that exsisted before into the new custom event, and then onpickupuse to the send custom network event with the same event name

[wind atlas]

Yeah, that's it. As you can guess from the method name, that event will be send to everyone to play the effects.

[desert swallow]

Cool, and now that I have it setup if i ever need a reference again I can go back and look at it

[bleak echo]

Not sure if this is the place to ask this, but...
I'm using the KurotoriUdonKart prefab.
How can I change the max speed? there doesn't seem to be an obvious way to do that. Even changing the MAX_SPEED variable does nothing. It won't go over 30.

[wind atlas]

Have you tried editing MAX_MOTOR_TORQUE too? Never used that asset or wheelcolliders, but it looks like it would be the main force. Another thing to try out is adjusting the rigidbody, check what the drag value is.

[bleak echo]

I multiplied both max speed and max_motor_torque by 10 and it didn't make any difference. I don't suppose those would cancel each other out...
I also don't see these values being overridden anywhere.

yeah still same thing, speed capped at 30

[wind atlas]

I'd have to setup up that asset myself and try it out to actually know what I'm talking about. All I can tell you is the information I have right now.
First of all, MAX_SPEED limits the actual movement of the car, make sure it's as high as possible when testing.
Next, MAX_MOTOR_TORQUE is responsible for how fast the wheels turn. That doesn't mean the car will move fast though! If you look through the car, you should find components called WheelCollider and a Rigidbody. The settings there will determine how fast the car actually moves.

[wind atlas]

Play around with the Rigidbody and WheelCollider mass. And probably the Forward Friction too. Good luck. That's all I know about this.

[bleak echo]

thank you for the tips, I'll play around with it and report any findings.

[minor garden]

Is there any insight as to why
GameObject.Find(_target).GetComponent<EventTest>().SendCustomEvent(_method);
works while
((UdonSharpBehaviour)GameObject.Find(_target).GetComponent(_component)).SendCustomEvent(_method); (when _component = "EventTest")
doesn't?

[wind atlas]

So _component is a string? I've never tried that, usually you'd do typeof(EventTest) which doesn't work in UdonSharp. So maybe your code get's compiled but crashes during runtime anyway?

[minor garden]

I do the typeof elsewhere

[wind atlas]

Use GetComponent(typeof(UdonBehavior))

[fiery yoke]

For non-VRC types you can use the generic version e.g. GetComponent<BoxCollider>() for VRC types you need to use the non-generic version like (VRCPickup)GetComponent(typeof(VRCPickup))
UdonSharpBehaviours do not exist at runtime, they are just UdonBehaviours. I forgot how it is handled during compilation.

[minor garden]

Ah, so they get cross-compiled out...

[fiery yoke]

Whats specifically wrong about that is that youre missing a paranthesis:
((UdonSharpBehaviour)(GameObject.Find(_target).GetComponent(_component))).SendCustomEvent(_method);

[minor garden]

If there are errors in parenthesis, that's purely a copy and paste into discord issue and would have already shown up in Visual Studio.

[fiery yoke]

To be clear youre missing a pair of paranthesese, that the compiler cannot detect as missing.

[minor garden]

ohhh... are you saying the cast is happening to the GameObject and not the Component?

[wind atlas]

🤔

[fiery yoke]

Or the result of the send custom event. Im not super sure about the precedences right now

[wind atlas]

My gut feeling tells me dots are first and type cast after, so the original block might be okay.

[minor garden]

Editor is showing the new parenthesis as redundant and gives the same result in playout

private UdonSharpBehaviour GetEventComponent(GameObject go, string componentName)
    {
        switch (componentName)
        {
            case "EventTest":
                return go.GetComponent<EventTest>();
            default: return null;
        }
    }

While not pretty, this seems to work

[grand temple]

huh? Why is that necessary?

why don't you just use GameObject.Find(_target).GetComponent<EventTest>().SendCustomEvent(_method); ?

I'm not sure if there are any situations where you actually need to use UdonSharpBehaviour specifically. It's either userclasses if you're dealing with a script you know, or an udonbehaviour if it's a script you don't know

[minor garden]

I'm doing a little rewrite of https://github.com/FairlySadPanda/UdonStringEvents.
I want to be able to call arbitrary methods on arbitrary GameObject Components

[grand temple]

then yeah, use UdonBehaviour

[minor garden]

except for some unknown reason, most likely to do with the cross-compiler, it just throws useless Udon Exception

[grand temple]

what's the code you're trying to do?

[minor garden]

You mean, like what method am I trying to call? I don't understand the question.

[grand temple]

what code is causing the error? And what is the error, for that matter?

[minor garden]

It fails on the SendCustomEvent

((UdonSharpBehaviour)GameObject.Find(_target).GetComponent(_component)).SendCustomEvent(_method);

[grand temple]

yeah, don't use UdonSharpBehaviour

just UdonBehaviour

[minor garden]

I've tried it both ways... same error

[grand temple]

Then it's probably not finding the object with that name

[minor garden]

it is
