I'm confused what you mean Adeon, I'm not sure how it relates to this
#udon-general
forest mist
pallid mango
No worries then
forest mist
There are multiple events in play
digital orbit
@digital orbit It's
Update
@forest mist So your flow looks like this
Update (every frame)
-> get player variable -> null, null, null, null
User picks up item and presses button, it finally sets player variable
Update -> get player variable (works)
If you use Start, it'll set it before Update runs
forest mist
Well that's the thing, it doesn't do that
Once the user picks up the item and presses it, nothing happens. The theory is that the script crashes because it's trying to set the position of an object to a player's bone's position.... but there is no player
digital orbit
Because once you get an exception, Udon stops processing. That's probably what's happening. All kind of weird things happen once it crashes
forest mist
Yeah, so I'm going to have to throw in a check for null values on the Update segment
digital orbit
Right. If player != null, then run that code
digital orbit
Why are you setting player like that though? Should not Start suffice?
forest mist
No, because the player should be determined by who "Uses" the item
It's meant to be an object you stick to your body
digital orbit
player is a local variable
forest mist
If I use Start then it will just stick to you as soon as you walk in
forest mist
Is there a good way for me to determine the player holding the object when it is used?
forest mist
I have to plug in a VRC_Pickup input into that though
Will it suffice for me to just make an empty public variable of type VRC_Pickup, since it will reference itself by default?
digital orbit
What you're probably wanting is to set the owner of the object, then you can get the owner of the object later too
Obviously, there can only be one owner. So, set the owner once someone picks it up. If anyone else wanted to know who's holding it, just check who's the owner of it. And if you wanted to know if the same player is the owner of it, set player variable in Start, and check if the player variable == getowner(gameobject), or you could just do a local boolean check and tie it to onpickup and ondrop
fiery yoke
VRC_Pickup will not auto-reference. You can do gameObject.GetComponent(VRC_Pickup) in nodes that looks a little bit weird
forest mist
I will see about doing that. Thank you both
By the way, I figured out what connected to that tt node from yesterday. It connects to HumanBodyBones, or HumanBones
Also @fiery yoke I found a few nodes that might be able to find the current player, though I don't know what the difference is between them
forest mist
Does Udon.... occasionally have trouble loading scripts?
I have 2 scripts which are basically identical. One works, and the other does not. I heard from someone that I might have to do some weird copy-paste thing?
Edit: That seems to have worked, strangely enough
digital orbit
Are you using the graph?
It stops working occasionally, even if there's nothing wrong with the script. I heard you can fix it by duplicating it
forest mist
Yup, duplicated the graph script and assigned the duplicate to the udon behavior and it worked. Crazy
fiery yoke
Graph Compilation sometimes breaks when doing certain actions. Its been a long standing bug.
Reloading the C# assemblies by entering/exiting playmode then compiling it again should also fix it
forest mist
Ah, I will try that next time, thank you
forest mist
I can't check if the variable is null.... because it's null.
Should I be using a different node?
fiery yoke
Show nodes
tropic canyon
I'm pretty sure you can null check vrcplayerapi
forest mist
Similar error
@tropic canyon I'm unable to find a node under VRCPlayerAPI that would be able to do this
fiery yoke
Can you try to log the variable?
forest mist
I'm not sure what you mean by that in this instance
fiery yoke
Can you also try Object.ReferenceEquals
tropic canyon
In u# just player == null
fiery yoke
just do Debug.Log with the variable as input
tropic canyon
and it works
forest mist
@fiery yoke Here's the log of the player variable
fiery yoke
Welp thats indeed strange
forest mist
Can you also try Object.ReferenceEquals
@fiery yoke
Well, that kinda works... it gets past that block but then errors because it attempts to find the bone of the player that doesn't exist. My guess is that SystemVoid is not the same as null and therefore technically passes the null check when using Object.ReferenceEquals?
fiery yoke
SystemVoid means that a method doesnt return anything
Thats not how that works
I have honestly no idea whats happening there.
tropic canyon
just get u#
fiery yoke
lul
rose arrow
@forest mist Don't use Equals use "=="
forest mist
?
rose arrow
I think it's op equality
rose arrow
It's automatically generated
fiery yoke
From what?
rose arrow
C# reflection
forest mist
just get u#
@tropic canyon I was hoping to avoid U# since it's very unfamiliar to me, but I might have to in the end...
rose arrow
Adding friendly names and aliases is planned though
tropic canyon
I'd argue it is as unfamiliar as the node graph
fiery yoke
I agree with that.
However @rose arrow it has been done with VRChatPlayerApi.Equals in the past successfully iirc
Ohh no wait
rose arrow
That won't work for null checks
rose arrow
It ends up being null.Equals(null) if the instance is null
fiery yoke
Yeah op_equality is the right one
fiery yoke
What is the other one?
rose arrow
If there isn't a VRCPlayerApi Equality you'll want this one
fiery yoke
Its easy to rememeber:
Equals means "I equals something else?" Equality means "The equality between two objects"
Equals is instance-focused, Equality is not
forest mist
Ah, gotcha!
fiery yoke
That is not much clearer to a non-programmer
rose arrow
It doesn't have an instance property
rose arrow
If instance is null you'll get a null reference exception.
fiery yoke
But again, to a non programmer that doesnt mean much
rose arrow
That's fair, the graph is still very much a WIP
fiery yoke
Most likely people who use graphs have no idea about the difference between instance and static methods
rose arrow
There's a new graph UI coming soon.
forest mist
I've programmed before, I'm familiar with == vs. .Equals
But in this case, it's not under the name "=="
rose arrow
Yeah, there's three separate names shown there so far
Object.Equality, UnityEngine.Object.op_Equality, and ==
fiery yoke
Some abstractions there might help
rose arrow
Better search is planned for some time after the graph UI
forest mist
So, progress!
Just a nullPointerException on the Bone node now
Which means it's passing through but I'm not sure how
tropic canyon
if(player == null) return; masterrace
fiery yoke
Thats kinda what theyre doing
forest mist
Logging the bool variable that comes out of the == shows it's returning true
Uh, false alarm
Looked like it was another compilation error. No more exceptions now after
fiery yoke
Yeah thats one of the most annoying problems
and the reason why most people use U#
its just more reliable.
forest mist
if(player == null) return; masterrace
@tropic canyon Trust me, my heart is crying out for some normal code right now
@fiery yoke I'll switch eventually
Maybe even tomorrow
By the way, is there any way for me to log what's going on in-game?
fiery yoke
There is an in-game console
Im tired of explaining how to open it
xD
Youll find someone who can help you with that
forest mist
Excellent question

It’s still incredibly annoying on the Swiss keyboard

is there a way to move an object relative to its parent during runtime? All the set/get for transforms seem to be relative to the world.

chilly aspen
Is it possible for an UdonSync variable to appear differently between players when OnDeserialization() fires? For instance, an UdonSync variable has the following properties in a class by a game object's owner who resides in Australia.
[UdonSynced(UdonSyncMode.None)] public int syncVariable;
void Start() { syncVariable = 0; }
void Update() { syncVariable = syncVariable + 1; }
Other players who live in various regions around the world have OnDeserialization() execute. Is it possible that, at an exact moment in time, a player in the UK could see the UdonSync variable as a different integer value than that of a player in, say Singapore?
For example, at a specific moment in time, the Australian game object owner would see syncVariable = 100 since he's in perfect sync with the variable. Singapore may see syncVariable = 92 upon OnDeserialization() execution. Could UK also see syncVariable = 92 upon OnDeserialization() execution? Or does UK see a different syncVariable integer value?
rotund thunder
raven peak
@chilly aspen onpreserialization is the event fired before a owner of the synced object sends the synced data to everyone else. Ondeserialization is the event fired when the other users receives that data. From what I’ve tested these events get fired before any unity event like Update. And the rate they usually get sent and received is 0.2 seconds for synced variables.
For sending the synced variables you could have it counting up by one during Update. But if you have it set to -1 or something else onpreserialization that is what will be sent to the other users.
delicate cipher
chilly aspen
@raven peak Ah, I didn't realize OnPreSerialization() was a thing. In that case, I think I have an idea on how to restructure networking. Thanks

Probably a stupid question - when you add an "Interact" and/or "Mouse Down" event to an object, does that automatically make it into a clickable button in VR and/or Desktop, or is there something else I have to do as well?

How do I fix the Rotating screen problem in VR CHAT, whenever I plug my controller it rotates my screen automatically please help
gray marlin
Is it possible to use Udon to read the color of a pixel on a texture?
or on a video screen or on a camera view
Actually @gleaming fractal described up above exactly what i was thinking
Did you ever figure anything out laser?
fiery yoke
You currently cant do that. What happens in GPU land stays in GPU land.
gray marlin
dont do me like this helpful 😭
fiery yoke
I wish just as much that it would be possible xD
gray marlin
that could allow so much cool stuff with having a video or a stream control the world
fiery yoke
You dont know how much that would enable
Going from GPU to CPU is always really complicated because of how different their architectures are
mighty fjord
Possibly doing some shader stuff for flashy effects but that's about it

How about reading audio...?

Well maybe it was possible but its much easier now
A realtime audio visualizer was pretty much the first thing I made

oh yeah this is way more impressive than the one i was referring to
i think what i was referring to just listened to some range of frequencies and just displayed their average volume basically
not like a visual analyzer like this

Probably a stupid question - when you add an "Interact" and/or "Mouse Down" event to an object, does that automatically make it into a clickable button in VR and/or Desktop, or is there something else I have to do as well?
@marble lark Interact makes it clickable in VR and Desktop. Mouse Down makes it clickable ONLY on Desktop. Yes, that automatically makes it clickable.
marble lark
Ok, cool! Was wondering since it takes forever to build the world, and I'd rather not go through the whole thing just for the simple button clicks to not work.
gleaming fractal
@gray marlin i did not
i hope something else comes into place to trigger
but it has to be something within the range that streaming platforms support.. supporting any weird other data poses a huge security risk which i doubt vrchat staff will undertake
for example another way would be if audio on streams would support a third audio channel which could be used for data like timecode ^^
But sadly i dont know a streaming platform supporting more then stereo
the last option would be a midi trigger to be supported among instances and the audio and performance work is already pre build into the world... its not great but that .. "could" be one
video with no audio track.
worthy beacon
does udon break if you try to vrcinstantiate an object in an occluded area?
tropic canyon
wdym by that?
flint urchin
No it doesn't. But current live has a bug with it. (Which will be fixed on the next update)
worthy beacon
ah ok
@tropic canyon basicly i have an object which is inactive that i use as my base to spawn. I just added occlusion culling to my map and noticed its in the area that gets occlued. The code was breaking and it breaks right around when it tried to spawn the brick
so i was thinking since the object was occluded (which it shouldnt of been) for some reason VRCInstantiate might of bugged the program
tropic canyon
scripts aren't able to be occluded
worthy beacon
its not occluding the scripts, its occluding the object which its attempting to instantiate
its probly not the issue, but i was assking if there was some bug, which accroding to phaxexNor there is
flint urchin
Occlusion only hides the mesh / disables specific things set to do so. The gameObject will still be there
uncut furnace
Yeah, yesterday's update broke VRCInstantiate in udon. Was working fine before the update and when I updated the SDK, couldnt spawn anything and logs showed the error: [UdonBehaviour] An exception occurred during Udon execution, this UdonBehaviour will be halted.
VRC.Udon.VM.UdonVMException: An exception occurred in an UdonVM, execution will be halted. ---> System.NotSupportedException: External module 'VRCInstantiate' is not supported.

feral elk
Hey quick question: is there an easy way to delay execution of an udon node? I'd like a trigger to teleport the player a few seconds after it is activated, but there doesn't seem to be any sort of delay or sleep node.
fiery yoke
That is a common question...I should really write a guide on it
Actually. I will
Give me a few minutes
feral elk
Ok wow thank you so much!
fiery yoke
@feral elk
feral elk
Alright, I'll give that a try! Thank you again for helping me figure this out
fiery yoke
It looks like much. And it is. But unfortunately there isnt really a much easier way
btw that whole graph looks like this in code:
float delayedTime;
bool isDelayActive;
void Interact()
{
delayedTime = Time.time + 5f;
isDelayActive = true;
}
void Update()
{
if (isDelayActive && Time.time > delayedTime)
{
DelayedEvent();
isDelayActive = false;
}
}
void DelayedEvent()
{
Debug.Log("Hello World!");
}
I'm trying to just check a float value based on its local transform, but it does not want to trigger at either threshold (I've checked that it is indeed exceeding them with debug.log) Am I missing something obvious in the check here?
And the code it goes to for reference. Basically if it's too far back, it should stop the plunger at the threshold.

Has anyone seen this type of error before? Can't find any info on it.
2020.06.19 01:40:06 Error - Failed to ready Doors because waiting for Door to ready
Where Doors is a parent gameobject with no udonbehavior and Door is a child with one.
Seems to break unrelated udonbehaviors in the world too I think
digital orbit
Is it a blank UdonBehavior?
timber lion
This happens with a "blank" udonbehavior on the child as well
I think it might have something to do with an Animator component. With the animator removed this does not happen, but I really need an animator on it. If I put the animator on a child of Door, it still happens though. About to try where the Udonbehavior is on Door but the actual door animator is on a sibling of Door
I'll also try where door has no parent in the scene, but that's really super not ideal
vague agate
Hello, if anyone knows how to use enum variable in udon, can you help me?
timber lion
Starting to suspect my issue has to do with disabling game objects with udonbehaviors on them which I forgot was a no no
even if it's in an animation
digital orbit
I've disabled UdonBehavior objects plenty of times with no problems
timber lion
Okay can confirm... the problems seems to have been with an animation enabling/disabling a gameobject with an udonbehavior on it. Note that the udonbehavior being disabled still worked when enabled/disabled via animation, and the log message didn't even say which objects were the culprit, just the name of some object above the animator in the hierarchy. This also disabled the Start() and Update() functions from being called by unity in unrelated udonbehaviors (other methods and network events still seemed to work and Start() and Update() coudl still be called manually)
I think a workaround could maybe be to set the scene gameobjects enabled by default and make sure the default mecanim state has them enabled as well but I'm not sure. already refactored my animation to enable and disable collider components instead of gameobjects to avoid this completely
timber lion
well it would be nice to enabled and disable an udonbehavior to change whether or not it is "OnInteract"-able and/or its Update loop happening
but I'm not sure its related. I think this is just some scene-readying issue
digital orbit
I wonder if you can reproduce it in a blank project with the same steps
timber lion
Probably and I could make a canny
digital orbit
That would certainly prove that's the culprit
timber lion
That's a great idea

So... turns out I'm still having issues with Equality of all things. Even after using the "==" node, I'm getting errors not when the object is null, but when the object is anything but null. So, as soon as I interact with the object
flint urchin
What’s the actual output log exception?
forest mist
@flint urchin I'm unable to find out, I don't know how to get that information in the VRChat game console, only in the Unity console
serene moat
You can look at your output log for the error, but the issue is probably that you're using UnityEngine.Object Equality instead of System.Object Equality
flint urchin
You can find the output log in this folder %userprofile%\appdata\locallow\vrchat\vrchat (Open Run and paste this)
serene moat
it's difficult to find in the node search but the correct node should look like the bottom node, where there aren't any names on the input pins
forest mist
For something this specific I don't even bother using the search, I went through the menus manually
Holy fuck it worked, thank you so much @serene moat and also @flint urchin

im trying to make a lock for a door how would i go about doing that is there some sort of variable where i can turn the script off on a different object or am i missing something and have the wrong idea haha if you can help me at all feel free to @ me or pm me ty 🙂
digital orbit
You mean like a keypad?
coral bay
like a private room where you can press a button and it stops people coming into the room through the other teleport button
digital orbit
That's simple
coral bay
lol im not the smartest with coding haha
digital orbit
Place a boolean on the other teleport button to disable it if true
Then, on the other button to lock it, SetProgramVariable to the other script
coral bay
ah ok ty
coral bay
yeah ty
digital orbit
To use SetProgramVariable, you'll need to put a public UdonBehavior on the lock button
Then drag the other teleport script into the slot on the lock button
In the inspector
Then you just SetProgramVariable on that public variable in the lock script
wide gyro
Hey guys, if I wanted to make it so that sound is heard by everyone in the room, how would I go about doing so with this script?
digital orbit
SendCustomNetworkEvent, and make a new custom event for it to go to, then play the sound in that event
wide gyro
Nice, thanks @digital orbit
digital orbit
And you can just duplicate the part where the audio plays so it'll be normal for the owner. OR, if you want the whole actiions to play for everybody, then just throw everything into the custom event (don't worry, it'll play for the owner too)
wide gyro
I'm trying to wrap my head around what that's gonna look like
digital orbit
CustomEvent foo
Then, route all those 3 nodes, Interact, onmousedown, oncollision enter, into a SendCustomNetworkEvent (name: foo)
Then, on the foo CustomEvent, throw everything you have into it
If you only want the sound playing for others, then keep it as it is, and just add the sendcustomnetworkevent in between the audio source play and rigidbody move rotation nodes, and make the new customevent, attach it to a new (but similar) audio source play
Just remember one thing: All custom network events play for the owner too. So, the owner will hear double sounds if you do that. Which means you need to filter out whether the customnetworkevent was fired on the owner or another person
wide gyro
oh god,.. do you happen to have twitch? I am streaming right now
and I wouldn't mind the help if you can see if what I'm doing is in the right direction
www.twitch.tv/cunningraven is where I'm at
digital orbit
Add a new custom event, name it whatever. Put audio source play into it
It depends on whether you want ALL those nodes to execute , or JUST the audio
trail turtle
Tip: You can also do a Discord call and just screen share, and you don't need a Twitch account to watch a stream
digital orbit
Ok, just the audio
Easy enough
Custom event, put audio play on it
Duplicate audio source play node, attach it to the custom event
THere you go.
Yes
RLIke that
Now , plug the audo source isntance to it like normal
Same place as the other one
Right
Ok, make a new node, sendcustomnetworkevent

sooo when instantiating a pickupable prefab its working fine in vr but in desktop the instantiated object is not pickupable. what am i doing wrong?

also sometimes it instantiates two objects instead of one
chilly aspen
i want to teleport my gameobject to its own position -12 units in the x axis, however vector3 subtraction is replacing the value for -12 0 0 instead of subtracting it from the object's position, am i doing something wrong?
@visual surge To teleport a game object to its own position -12 units on the x-axis, it'll be either of the following lines of code (one long and one short):
this.gameObject.transform.position = this.gameObject.transform.position + new Vector3(-12f, 0f, 0f);
transform.position += new Vector3(-12f, 0f, 0f);
The graph posted looks syntax-correct. Maybe try pulling the game object and vectors from it's own node not being used elsewhere. I've had complier issues where I'm pulling multiple noodles from one node, and the assembly code wasn't structured correctly.
chilly aspen

also sometimes it instantiates two objects instead of one
@visual surge Instantiate for Udon Graphs is not working correctly, I believe. Works fine for UdonSharp though.
visual surge
thanks, i managed to make the teleport work properly
i guess i should look into using udonsharp then if it works better
flint urchin
@visual surge What's the current set up for your instantiate? (graph screenshot)
Because instantiate in graphs works just fine
visual surge
basically after passing through a few branches it instantiates an upgraded version of the object at the same rotation and positon(with an offset of -12 x ) and then destroys itself
it seems to work fine however sometimes it spawns multiple objects and sometimes only one
and also the prefab has a pickup component but it seems to not be pickupable by some people and work normally for others
the prefab
i thought it could have been because the collider was set as a trigger but changing that did nothing different
flint urchin
Make sure the prefab is in the scene descriptor prefab list. (shouldn't matter, but better safe than sorry)
For self, you don't need to do a public variable, just use the This node
Use SetPositionAndRotation (performance reasons)
Does each player spawn their own object then I take it? (as in spawns are triggered via a custom network event)
visual surge
prefabs are all there
there is also one of each in the scene already
the behaviour is completely local nothing is synced
each player starts with a set number already spawned in the scene and then can upgrade it
not a network event just a simple ontriggerenter, since its suposed to be local anyway
flint urchin
Are the collision matrix set up properly then? So it doesn't collide with the player
visual surge
positive
the objects dont collide with anything but another layer where the trigger is on so they can detect each other
flint urchin
As for why it's not pickup able for some I don't know. If the cards are inside other trigger areas, that could be why desktop can't pick them up. Since raycast is blocked by the trigger, unless it's on the mirror reflection layer (this would be for other triggers than the cards)
visual surge
what about the double spawning? any clue?
flint urchin
That could be as much as them clicking it twice
visual surge
no clicking involved
they place the object in a box wich has an animation for moving the collider within it making contact with the object and activating ontriggerenter
the animation also has a cooldown time
cannot be played twice until its finished
flint urchin
Well, it's triggered twice somewhere 👀
Add a branch in the beginning to check if it's already being processed, then as the next jump you set the bool value to true.
So if it does trigger again it will be True and not do anything again

I want to change the texture on an object's material via Udon. In start, I fnd and assign the game object in question to a variable. Then on button press, I get the MeshRenderer component from the game object, get the material from the mesh renderer and call "Set Main Texture". Everything but the last call seem to work. When calling Set Main Texture (where I dragged a different texture into the value field), unity throws a null error (I assume it can't find the texture?)
fiery yoke
Texture Variables are not yet implemented. I dont even understand how you got to that step at all
fiery yoke
Ohh thats interesting. Didnt know there was a specific method for SetMainTexture

Okay, so basically what I want to do: I have a plane where I want to dispaly randomized cards on button press. That's why I want to exchange the texture
Would material swap work instead?
fiery yoke
I guess. But all of that is pretty expensive
Funnily enough Im working on a Card system as well right now 😅
sinful slate
haha
fiery yoke
sinful slate
what's your approach?
fiery yoke
Using a custom Shader with a property that decides which part of the Texture is being used
Dont need to switch textures, materials, or even gameobjects
sinful slate
ah well, i use pretty large textures, since my cards are about 2 meters tall 🙂
so well… gonna try out if material swap works
hm, so apparently to set a custom material, you have to call Resources.load()… but there is no such thing in udon >_>
fiery yoke
No you dont
sinful slate
enlighten me 🙂
fiery yoke
Just put a material in a Material Variable
sinful slate
how to put it in? 🙂
fiery yoke
In the inspector. Make it public.
fiery yoke
They are supposed to indicate which type its using
however...that doesnt quite work because of boxing
swift cape
So I have 3 toggle interactables for mirrors around my room. It seems randomly desktop can't click some of them, or they become really finicky to actually interact with, or VR can't interact with them. I remember someone asking a similar question but I can't find it. Is there some trick to getting these interactables to be more reliable?
this is the script that all the interactables use
flint urchin
Do you have any triggers (colliders) near/on where these interaction points are?
sinful slate
is it just me or is the udon graph editor getting really slow once a lot of nodes got added?
fiery yoke
It shouldnt get to a crawl, but it does slow down the more it has to draw yes
The graph is currently being reworked, so maybe it will be better after the update.
swift cape
@flint urchin actually yes. I have a big bounding box trigger that turns off the mirror when people get too far.
fiery yoke
Put it on the MirrorReflection layer
flint urchin
👆
fiery yoke
swift cape
upvoted
Ok, but wait. I have it set up so that it's on a localCollision layer such that it will only fire when the local player exits. Do I just need to do this in a different way?
swift cape
I'm guessing the other worlds that do this successfully just have trigger boxes in doorways and such
swift cape
Right, that might be weird for my grabbable mirror
fiery yoke
Yeah its an annoying problem that been around forever
swift cape
What if I use like an update loop that just keeps checking the proximity of a player to all the mirrors in the room and disabling the ones that are too far?
fiery yoke
That would work I guess
swift cape
I have absolutely zero intuition on performance right now, but I think I'm going to give that a try. My world is all hilly, too, so using that thin collider method would be finicky even for the stationary mirrors.
but, as I understand it, the issue arises when there's a collider around the interact object, so I could perhaps just stick the interactable just outside of the bounding box somehow. Maybe right on the ground.
fiery yoke
Well if a raycast starts inside a collider it wont collide with the "inside walls"
Basically Colliders are Backculled. Just not in terms of rendering, but collision detections.
swift cape
Alright, I'm not sure what I'm doing wrong here. I verified that plugging the debug output directly to the Update event does print to the console, but how it's configured here does not fire at all.
fiery yoke
That alone probably wont fix your problem tho
swift cape
Yeah, I also tried just plugging in a value directly into the end of the for loop and it also didn't output. Is there a place that shows udon compilation errors?
or runtime errors with more detail?
fiery yoke
Not really
swift cape
cool cool
fiery yoke
If the graph is behaving weird
I recommend to:
- Go into playmode
- Exit playmode
- Recompile Graph
I literally do that every time I work on the graph
swift cape
this is giving me a lot of appreciation for Rec Room circuits which is something I didn't think was possible given all of their weirdness 😛
fiery yoke
All I can say is that theyre working on improving user experience with the graph.
swift cape
Yeah, I'm not bashing at all. I know what I signed up for. Alright, going through those steps didn't seem to resolve the issue. Here's my whole graph
just checking when you say "Recompile Graph" you're referring to clicking the "manual Compile" button?
fiery yoke
iterating over an array on Update has had performance issues in the past. They have supposedly been improved, but if youre having frame issues then thats probably why.
Yes
swift cape
What I'm expecting is the debug log to output in the console like it does if I plug Update directly into the debug node.
This script is supposed to be disabling the mirrors when the player gets too far away from them, but it's not working, so I'm trying to trace the problem.
Once I figure out how to get this to work, I could probably replace that Update event with something less frequent, like a check every 5 seconds or something.
Oh wait... Get Position doesn't like that there's no local player
that's the issue.
yay it works!
barren plover
is there a wall of people who have been banned from this server and how do i get on it
zenith river
doesn't seem to be a udon related question, but the answer is no, there is no wall
fiery yoke
@zenith river Dont even give those trolls attention
swift cape
Is there some obvious reason why my logic for resetting the position of my grabbable object isn't working?
I've confirmed that the ResetMirror event is firing
swift cape
It's not synced, no.
fiery yoke
Hmm then no
Ohh xD
Actually yes
You put a Transform into a Vector3 and Quaternion
Use Transform Get Position and Transform Get Rotation
swift cape
hek, so I have to extract that. Oops
I should have known
for some reason I was putting faith that if it allowed me to make the connection then it was being smart about resolving that information, but in this case I should have known better.
fiery yoke
Yeah imo Transform.SetPositionAndRotation should have an overload for Transforms
swift cape
Does udon have a concept of like... custom nodes?
swift cape
affirmative
tropic canyon
what like a custom expression node like amplify?
where it's literally normal code
or just a bigger picture of a bunch of nodes
swift cape
Like, if I wanted to encapsulate a bunch of logic that might be used a lot into a single node that's easier to reuse. For instance, these nodes might be nice to get put into a custom node with just a Transform input, instance input, and control flow input.
so you could open it up and see these three nodes, or leave it closed such that it's a single node.
encapsulation
Ok, huh. It's still not working. Hmm...
fiery yoke
Yeah thats planned
vagrant coral
ive ran into some wierd issue now... when i make a new udon program i cant edit it... like the "Open Udon Graph" does not show up...
oh it turns into a "assembly program asset" rather than a "udon graph program asset"
oh there is a drop down menu thingie... No more confusion! 😄
swift cape
Just checking, there's nothing bad about using multiple Udon Behoviours on one object, right?
fiery yoke
It can only confuse other VRC stuff like Pickups and Stations
swift cape
how so? I do have this pickupable mirror with VRC Pickup script and I wanted to add both a ResetMirror script and a ResetPosition script; should I instead combine them into one?
swift cape
I'm just still having problems with this resetting position script and I'm trying to figure out why. There's something I'm not understanding.
tropic canyon
did you sync position?
swift cape
I did not
tropic canyon
try to Rigidbody.MovePosition
with the rigidbody of the pickup
I'm unsure if you can edit the position while it's held too
I'd make sure to VRC_Pickup.Drop()
then try and set the position
swift cape
Alright, the issue came back to a misunderstanding with custom events. Turns out they can only be sent to one Udon Behavior component per object.
I didn't realize I needed all of this to send a custom event
flint urchin
If it's a event that is on the same behaviour, you don't need to do that.
It's also better to just directly have a public udonbehaviour variable and use that (unless it's a trigger/collider)
fiery yoke
Welcome to the Udon-club. We have Aspirins and tissues.
If you want to send custom events to multiple behaviours, use an array and loop through it
swift cape
I'm trying to iterate over a list of game objects, but it seems like I couldn't just set an UdonBehaviour[] public variable
fiery yoke
No
UdonBehaviours have no arrays
for whatever reason
Youre right. Welp
As I said. Aspirins and tissues*
swift cape
And also this method seems to only pick the first UdonBehaviour component, so using multiple UdonBehaviours on a single object is not an option
fiery yoke
Yes
Thats another issue
you can get All Components
as a Component array
and in U# its easy to go from Component to UdonBehaviour
swift cape
Oh, and then filter by UdonBehaviour type?
fiery yoke
Yeah
However that gives you a Component array
I suppose as long as theyre the right components you can just assume that it will work
swift cape
ok. I know of U# but I'm actually trying to use noodles to get ready for Rec Room's circuits v2 which is basically the same thing
the good news is that all of my udon goals for today are working ^.^
now for extra
fair beacon
Woo
idle kite
hey so i recently added respawn buttons to a few dice in my world using this Udon graph, but for some reason when i try to respawn the dice it sometimes bugs out and the dice don't return, but they instead start to flicker if you keep clicking the button, anyone know a way to fix this?
fiery yoke
Are they position synced?
idle kite
yeah synchronize position is ticked
fiery yoke
Then you have to send a networked event to the owner and tell them to reset the position
Also if it has a Rigidbody dont forget to also set Velocity and AngularVelocity to 0
flint urchin
There is also no way to disable lerp on synced objects at the moment, so everyone except the owner will see the object float towards it's destination
idle kite
ahh i see, okay thank you
visual surge
is it possible that udon instantiate or vrcpickup change depending on hardware? i have an instantiated pickupable object in my world that i cant pick up but my friend can, later i found that he has an amd processor and i have an intel one, additionaly i tested with a few other friends and all the ones who have intel processors were not able to pick up the objects. Objects that were already in the world are pickupable by anyone but the instantiated ones only seem to be pickupable by whoever has AMD cpu. Has anyone else encountered anything similar?
visual surge
after more testing: people with nvidia + intel cant pick up, people with nvidia + amd cpu can, people with amd gpu + intel can
so im completely lost on why its happening or how to fix it, the only way around i can see is giving up on instantiating and using a pooling system instead
flint urchin
I have nvidia + intel and can pickup items after instantiation
visual surge
on the current update?
then i have no idea what else would cause it lol
back to the drawing board
hoary ocean
how would I do a simple if statement?
I could try while, but it hasn't seemed to work so far
flint urchin
branch is if else
hoary ocean
awesome
thanks bunch
Another question. I keep getting 0 errors, yet when I start testing, it doesn't load my new program. I make sure to manually compile each graph.
tropic canyon
Did you put the programasset into the udonbehaviour property?
hoary ocean
yeah, it seems to be an issue with my unity, it's not saving any changes to anything
hoary ocean
I think I have it handled now
visual surge
is there anything different between a local testing build and a published one? when testing my build locally i am able to grab my instantiated pickups normally while in the published one i am not
visual surge
so i finally managed too make all my pickupables work normally
turns out addding them to the dynamiic prefabs list is acctually what broke them
as soon as i removed every prefab from the list they all started working normally again
digital orbit
As far as I know, that's automatically generated and you shouldn't be messing with it
No difference between local and published. Except nobody else can join a local one obviously. And you don't have to upload it
sinful slate
I'd like to disable collision between specific pickups, while maintaining collision with the rest of the world. I've seen small board games doing that – any idea how to achieve that?
Also side question: Rarely when putting a pickup down (or them respawning), I see them all suddently glitching/flying all over the place, anyone knows the source of that issue?
zinc thicket
@sinful slate That's a physics layer (Vanilla Unity) thing. You can set certain layers to not interact with each other.
It's under Project Settings > Physics and then use the matrix (triangle) to pick which layers can interact with each other and which ones can't.
Then just set the layer or whichever object you want the special properties. Careful not to change or clash with existing layer numbers if you use multiple layer "hacks"...
scarlet lake
Does anyone know how to make a object move with out it following your head, and I'm trying to make the object move as well.
swift cape
I have a door with an animator that I want to open whenever someone is nearby, this is what I have with a box collider surrounding the door on the default layer. It doesn't seem to be triggering the animation and I just want a sanity check that the problem doesn't exist in my udon
the script is counting the number of people inside of the box trigger and keeping the door open as long as there is at least one person nearby
I don't think I need to synchronize anything; each client should be able to keep track of this on their own afaik
long rune
Is this global? I tried doing something like this but did not succeed.
fiery yoke
It depends on which layer you have the trigger on
long rune
what layer would you suggest?
swift cape
I'm not sure what that means
what does it mean for something to be global?
I've set the trigger to be on the Default layer.
long rune
Where both you and another can both the the animation when it triggers.
swift cape
Yeah, that's what I want the trigger to be affected by both local and remote players.
fiery yoke
@swift cape If its on the default layer it will also count stuff like pickups, the players camera. Basically everything. Not just players
swift cape
Oooh
so should I make a new layer then?
or can I use the Player layer?
That seems like it might do what I want
fiery yoke
Player also collides with a lot of other stuff
you would need a layer that just collides with Player and PlayerLocal
swift cape
Alright, so I'll just make a new layer, then.
long rune
I have a simple trigger setup for an animation(a door) on the default but I tested it and only I see the animation.
I do need to make a new layer as well, I'll send a screen of my simple setup here in a few.
swift cape
oooooh, I figured out the problem with my script at least. Like a doofus I forgot to plug in the animator variable into the Animator Set Bool node >.<
long rune
I need to update the sdk real fast then I'll share what I have :)
long rune
lemme know if you get that working as intended @swift cape I also want to have a door open automictically 
tropic canyon
can also sendcustomnetworkevent to open and close the door
fiery yoke
Unneccessary
tropic canyon
¯_(ツ)_/¯
long rune
I am still working my head around this Udon ¯_(ツ)_/¯
tropic canyon
it's the unity library and some of the system library but missing a ton of stuff from them
swift cape
I think I should be able to avoid networking
like, each client knows where all the other players are, so they should be able to keep track of if there is anybody near the door, right?
tropic canyon
sure
swift cape
I need to figure out how to test multiple clients locally
tropic canyon
do the multiple client local testing.. it should be fixed afaik
swift cape
@.@
flint urchin
It is. Make sure the path is correct and set the number of clients (max 8)
fiery yoke
Is the max enforced by VRChat because more than 8 would cause some sort of problems, or is it just an arbitrary max so you dont spawn in a hundred clients
tropic canyon
¯_(ツ)_/¯
swift cape
so yeah, @long rune it was enough to create a new layer that just collides with Player and localPlayer and then I used this Udon to toggle the door's animator.
Yup
swift cape
I'm keeping count of how many people are near the door
long rune
I just would also like this option on which you have provided :)
swift cape
if you just toggle, you'll end up with the door shutting in your face when anyone walks out of the doorzone
really you want the door to be open as long as there is >= 1 person near it
long rune
Makes sense.
fiery yoke
= 1 is same as > 0. Just saying :P (For Integers)
long rune
The problem I have with my toggle, the animation is client side.
So I will see if the layer is my problem
swift cape
all clients know about the animation, so you just need to arrange it so that all clients can detect the trigger to activate the animation.
long rune
Still waiting on unity
scarlet lake
still need help on how to make a object stay still while i move around
fiery yoke
@scarlet lake If youre talking about avatars then this is the wrong channel. #avatars-2-general
scarlet lake
avatars channel right?
long rune
This is what I have for my toggle, I do have it on the default layer. How do I do the client test?
Looks like I just need to up the client number
tropic canyon
interact is locally called
so if someone presses it it's only for them
as everything in udon
long rune
Oh, I see. How do I go about making it global?
tropic canyon
either have a synced variable or sendCustomNetworkEvent
so on interact branch with a bool
calling 2 new events
and I guess in the event set the bool
long rune
branch node after interact then two events?
long rune
that's what I am doing right now, guessing.
tropic canyon
Interact -> check bool -> sendCustomEvent to opposite value
customevent -> set bool -> do animations etc
oh no
it won't sync when a new player joins tho
they will see the initial value until someone interacts with it
also some people could spam interact it
tropic canyon
:/
fiery yoke
You can sync with events
OnPlayerJoined -> Ask master what the current status is -> Master Broadcasts status
Wrong channel
long rune
Yeah, I'm not sure what I'm doing now
cedar cove
Quick question, if a synced variable is assigned the same value it already has, does it actually sync? (and fire the serialization methods)
fiery yoke
Good question. Not sure but my intuition would say no
long rune
I've always wondered, I use Unity's UI elements a lot, I have set a toggle with the transition being animation, mind you that I have a toggle group for multiple toggles. I play the editor, hover my mouse and it plays the animation, I insert the VRC UI shape then upload the world(using UDON). The animations do not work now but still function as a toggle. Any clue why this is?
Is this just a Udon thing with UI elements?
hasty zenith
So my in game name is as spelled in discord.
Scarecrow.exe
Pretty sure you cant use the period anymore when creating a username but i got mine before that was changed so i'm grandfathered in and realyl like my name.
Seems to be messing up Udon string values though and we're tryna figure out how to fix that. Would simple quotation marks work? like "Scarecrow.exe"
hasty zenith
Again, asking for workarounds first, but we figured as much
Is this a known thing that they'll try to fix on the udon/vrc side?
raven lark
What do I do? My avatar is broken. I can only move to the right and left. I do not know what do to. HELP ME!
fiery yoke
@hasty zenith Best solution I can think of is converting the string to Base64
long rune
the multiple client local testing working for you guys?
raven lark
And I can't click anything!
fiery yoke
@long rune yes
long rune
Mine seems to not work? One client spawn into my world with the updated world but the other at default home.
raven lark
It doens't work! A random avatar thing gave me this avatar.
long rune
You're in the wrong channel my guy...
long rune
safe spoke
Yo guys, having issue with "Check whether your pc has working internet connection and restart VRChat" any fixes? Sorry if wrong section
long rune
Nice one.
So how does multiple local client suppose to behave? My questions go unanswered.
tropic canyon
like normal
long rune
Wow, an answer that totally helps me out. Thanks a lot!
fiery yoke
Well...thats it tho
the only "difference" is that all clients have the same user/display name
Other than thats its like having multiple accounts on the same pc
long rune
do both clients spawn in the same world together?
fiery yoke
They should yes
long rune
That's all I needed to know. Mine seems to not be working even tho I have the latest sdk.
long rune
I do have it set to an .exe
fiery yoke
You do
tropic canyon
fiery yoke
It doesnt work with the bat
tropic canyon
😎
long rune
Even after so, it still behaved the same. I want to use this feature so I don't have to rely on someone to help me test out my systems.
fiery yoke
The SDK uses a path saved in the registry by default. That however points to the batch file, which for whatever reason fails to launch local clients correctly.
long rune
Hopefully I get it to work, anyways thanks.
copper gale
umm anyone know how i can change to my favourite avatars in a different world on pc?
scarlet lake
I know
hushed gazelle
Is there any reason why this wouldn't be destroying a detected spawned prefab object? I know it's detecting the ball entering the box as it sends the udon command afterwards, but it wont destroy the existing ball
hushed gazelle
I tried that, didn't seem to work either.
All it seems to do is strip the sphere collider from it rather than kill the whole object.
hushed gazelle
Ahh, cheers!
I did do a search to see if there was a get object node, but the search function's... not great.
That worked. No more errant pinballs falling away into the ether.
worthy beacon
has anyone experienced increased lag on their udon maps after the resent updates? My map didn't do this before, but if enough people are playing, the lag will start to hit hard enough to cause people to disconnect
forest mist
Does anyone know anything about mechanics of rotating objects? I need to be able to adjust the position of something based on its rotation and relation to an object. For instance: this hat that rotates as the head does, but does not change position to account for the rotation.
tropic canyon
do you want to learn about quaternions or do you want an easy solution?
tropic canyon
easy solution is parenting
move the parent of it to the head bone
and move the hat under it to the right position
and just rotate the parent
fiery yoke
You can also use a Parent Constraint afaik
forest mist
The hat currently has no parents. So, I'm creating an empty GameObject around the hat?
@fiery yoke What do you mean?
tropic canyon
parent constraints are weird..
just making an empty is a lot easier
if you can reparent the parent constraint is useless
forest mist
Hopefully I can keep it all in the same Udon script... I don't want to be throwing custom events around
fiery yoke
I like the parent constraint because it doesnt mess with your hierarchy
But whichever you prefer-
forest mist
There is also a mathematical method using Quaternions?
Though I assume that's much more complex
zenith river
Hm, why not have an empty following the exact head rotation and location, then parent the hat to that empty, no need for the complex maff than
fiery yoke
Quaternions are 4-part complex numbers. They are mathematical constructs that are hard to grasp.
tropic canyon
Quaternion rotation = currentPlayer.GetBoneRotation(bone);
position += rotation * offsetPosition;
rotation *= offsetRotation;
visual.SetPositionAndRotation(position, rotation);
rb.MovePosition(position);
rb.MoveRotation(rotation);```wait wtf is that indent..
zenith river
Aah math!
fiery yoke
@zenith river That is exactly what @tropic canyon was proposing
Parenting is the easier solution
zenith river
Ah right
forest mist
I've had to slightly touch on quaternions in order to even get the hat to follow the correct rotation. But yeah, I don't really get them
tropic canyon
quaternion * quaternion is like adding
forest mist
Yeah :D
And quaternion * (inverse)quaternion is like subtraction
tropic canyon
and quaternion * vector3 rotates that vector3
forest mist
Ahh, I gotcha
forest mist
I was trying all sorts of quaternion * Vector3 stuff to try to get it to work!!
I guess I just didn't have the right combination
tropic canyon
so quaternion1 * quaternion2 != quaternion2 * quaternion1
forest mist
Yus
That was a pain in my ass because it goes against everything I learned in school xD
tropic canyon
matrices aren't commutative
fiery yoke
Maths is hard.
tropic canyon
matrix 1x3 * matrix 3x1 != matrix 3x1 * matrix 1x3
forest mist
I'm not entirely confident I know what "matrix" means in this context
fiery yoke
A Matrix is just a "grid" of numbers
tropic canyon
matrix is a multidimensional array of floats
zenith river
Oh wait, so just think of them as matrix?😲
tropic canyon
😳
zenith river
Uh oh, well back in the dunce cave I go
tropic canyon
everything in math is somehow related
fiery yoke
Quaternions are described as "the quotient of two vectors". They are generally represented as "a +bi + cj + dk" where ijk are imaginary and abcd are real
forest mist
Well yeah, I know people have made it before :<
I wanted to challenge myself with this one. And I’m making it for a friend
forest mist
position += rotation * offsetPosition;
I’m out right now but I’ll try this as soon as I have the opportunity. Can’t believe I was so close but had the wrong numbers.
Thank you for the help @tropic canyon

So what’s the current situation with YouTube Live videos. I’m in Volt and I need to stream in a youtube live video tomorrow. I see lots of chatter about this topic but most of it is old.
worthy beacon
So i take it no one knows of any current issues with the last update that could be causing network lag to the point of disconnection related to udon?
fiery yoke
Thats quite vague
worthy beacon
the spesific is did the last update introduce a bug that increased lag related to use of udon XD
my bomberman map has never done this before, but after the last update it starts to get more and more laggy, then eventually disconnects people
and i didnt touch anything related to the code in the last few updates, only added map optimizations like light baking and occular occlusion
like was there a new memory leak or somthing?
fiery yoke
Hmm...there were some significant changes yes
worthy beacon
the disconnect also causes the person when they rejoin to desync with everyone else in the world, havnt isolated spesific causes but basicly people wont show up for others, avatar and all
i suppose ill do more to try and debug it and report the bug
forest mist
@tropic canyon Following up on the code you wrote earlier, it worked great, but it's introduced this strange issue where on first activation, the hat does not place correctly. Do you have any idea why?
Here's the way I've laid it out btw
tropic canyon
oh
it might be you not calculating the positions correctly
it's..
a little indepth
forest mist
It's strange that it positions it fine before I added the Quaternion*Vector3 node though...
tropic canyon
Vector3 tempPos = tempPlayer.GetBonePosition(tempBone);
Quaternion tempRot = tempPlayer.GetBoneRotation(tempBone);
tempRot = Quaternion.Inverse(tempRot);
offsetPosition = tempRot * (transform.position - tempPos);
offsetRotation = tempRot * transform.rotation;
this is the code to get the offsetposition and rotation
you need the local position of the object
you can't just give it the global one
as goes for rotation
forest mist
Won't the global and local position be the same, considering that the hat has no parents?
Or does it work differently than that?
tropic canyon
the quaternion code I sent operates like local positions
like the head was the parent
forest mist
Ah, I see
forest mist
Interesting, I see!
I also have my own code for figuring out the offsets, though my variables are called "differential"
I will compare my formula to yours and alter it as soon as I'm able to
Thanks a lot!
forest mist
I have it on onPickupUseDown
So you "click" or "use" the hat on yourself to attach it
tropic canyon
sure
warped herald
Hello, will udon support Gradient in the future ?
swift cape
Someone showed me an avatar that breaks all box triggers in my room. I'm not really sure what the avatar is doing but I'd like to know if a mitigation exists to make box triggers more reliable.
What I think is happening is that when they equip the avatar, it makes all the box triggers fire an onEnter event, but then there's no onExit event fired for some reason, which throws off the count of players inside the volume.
zenith river
maybe they are using an occlusion cube and forgot to remove the collider 🤔
swift cape
in my case, it's with the doors in my room. As soon as they equipped the avatar, all the doors opened, but they remained open after they unequipped the avatar.
tropic canyon
can't account for all avatars sadly..
fiery yoke
If people use avatars that break stuff its their problem. Unless its the majority.
tropic canyon
only way to mitigate would be if the layers were setup differently
like player layer only being the pills
not every collider on the avatar aswell
that would also fix the auto mirrors
swift cape
that seems reasonable for the doors at least.
spring forge

Right shift

when having two pickups with gravity and such – can you disable collision between those pickups?

Have them on a layer that cant interact with its own layer (Exemple: objects on the "player" layer cant collide with other objects on the "player" layer)

Theres probably some way to work around that issue now though

You get the collider from OnEnterTrigger, then get the gameObject, then the layer it is on, and compare it to a LayerMask. However be aware that when colliding with protected objects such as the player, it will return null. So you have to make some null checks.
grand temple
Are you using graphs or udonsharp?
grand temple
I'm not sure if layer masks and bit shifting can be done properly on graphs, so I would recommend just having an int that represents the layer you want to check for. Then just check if gameobject.layer is the same as the layer you want to check for

I feels very strange compared to how it was with just triggers, but I think it might be workable enough. I appreciate the advice. would some more advanced stuff be better with U#?
grand temple
Yeah it's easier to deal with U# when things get big or complex
hoary ocean
another question. if I am trying to move another object, would I refer to its transform then do a set transform with a get variable?
let me show you. in theory, this would move an object to the first point of collision, yeah?
grand temple
Correct, but two things: you need to check if collision.collider != Null before doing anything else, and also are you aware that oncollisionenter refers to two objects bumping into each other, not a trigger collider entering into another collider?
hoary ocean
I am really just trying to make a block move to when I collide an object with anything, and show me first point of contact. it's more for the learning aspect. my issue comes into play when the block simply doesn't move.
(it is added to the external references)
grand temple
That's probably because the behaviour is crashing when it encounters a protected object
That's why you need the null check
grand temple
Looks ok
hoary ocean
well, I have a trail that follows the item based on its angular velocity, that's not stopping on collision anymore. so it isn't crashing, but the other object seems to not be moving still
I had ghost noodles, which bugs me. definitely moving to U#
hoary ocean
I'm actually almost kindof mad at how easy that was to do in U# lol

You want the #avatars-2-general channel.

How do I trigger a hinge joint with Udon? I know how to change the force and velocity with an animation, but I can't seem to be able to get at those values with Udon.
tropic canyon
they are part of the rigidbody
afaik
so rigidbody.velocity and rigidbody.angularvelocity
hushed gazelle
Ahh, cheers.
I can't see how to actually set a HingeJoint's motor. I can GET the JointMotor, but I can't assign anything to except the Type.
tropic canyon
it might not be exposed you gotta check
with some things you got to store it in a var before accessing the settings like the particle system emission
warped herald
is there a way to zoom in/out in udon editor ?
tropic canyon
in the new one yes in the current one no
digital orbit
is there a way to zoom in/out in udon editor ?
I estimate it'll come soon, it's still in testing right now to work out any issues
warped herald
i hope gradient support will come:)
visual surge
is there any way to override one of the player inputs, like replacing the ability to jump for something else?
fiery yoke
@visual surge The short answer to that is no.
zenith river
long answer: no, but you can listen for the key event and trigger an action that way
tropic canyon
You can take away the ability to move
zenith river
ill take away your ability to move 
flint urchin
Can also not enable jump in the world 👀

Why use VRCPlayerApi.Immobilize when you can force Player into a Station they cant exit :^)
zenith river
actually, how do you put a player in a station with udon 🤔
fiery yoke
Station.UseStation(VRCPlayerApi)

I have a question. Imagine the following code executed by a master player where boolVariable equals false:
SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, "SetBoolVariableTrue"); // Function that sets boolVariable = true;
if (boolVariable) MethodA();
In this scenario, is it possible for there to be a delay in setting boolVariable to true, preventing MethodA() from being called for the master player?
fiery yoke
Alright sorry. Reread it a few times
fiery yoke
@chilly aspen Yes ofcourse there is network delay. When you "SendCustomNetworkEvent" it will take network time until the message has arrived.

How would I make triggers work with one object only?
E.g. making a trigger only work if a player enters the trigger, like a collectable can only be picked up by players
I know in C# you'd usually use other.tag == "Player" but I don't see the ability of using that anywhere in udon
marble lark
OK, I'm having a dumb problem - I can't get Interact events to work. Gimme a sec, and I'll get the Udon Nodes and Inspector View for it...
One of the buttons - they're all the same, minus some object differences.
Same Button, but from the Component Inspector side of things...
fiery yoke
You need a Collider.
fiery yoke
The Collider is for Collision detection. The Mesh Renderer for Rendering.
If you want to see your object, then a mesh renderer would be quite neat :P
marble lark
Nah, the buttons themselves are textures on a pad, I just need separate interact boxes for each one. I think I tried earlier with a collider and no mesh renderer though, and afair that didn't work either. Hang on, Imma try it again.
marble lark
Nope, that didn't work either. Does it have to be a Trigger?
digital orbit
Make sure to click the convex option if it's a mesh collider
marble lark
Figured it out - turns out you can't use buttons inside other colliders...
Should have realised that one, it's kinda obvious thinking about it...
digital orbit
Any idea why I can't pickup objects that have a pickup script on them?
I can pick them up, but sometimes they fall in a certain place, suddenly I can't pick it up anymore
fiery yoke
Most likely other colliders blocking them
