Udon Events

These are the method stubs you can override via UdonSharpBehaviour.

• VRChat Event Documentation

These methods have to be public

public override void <method>() {}

void	Interact()	Fired when a user interacts with the object Will add a box collider if no collider is present.
void	OnDrop()	Requires VRC_Pickup
bool	OnOwnershipRequest(VRCPlayerApi requester, VRCPlayerApi newOwner)	Fired when an UdonBehaviour is going to change owner. Returning true will accept the change in ownership, and returning false will reject the change in ownership.
void	OnOwnershipTransferred(VRCPlayerApi player)	Fired every time a UdonBehaviour changes owner
void	OnPickup()	Requires VRC_Pickup
void	OnPickupUseDown()	Requires VRC_Pickup
void	OnPickupUseUp()	Requires VRC_Pickup
void	OnPlayerJoined(VRCPlayerApi player)	Fired when a new player joins the instance
void	OnPlayerLeft(VRCPlayerApi player)	Fired when a player leaves the instance
void	OnPlayerRespawn(VRCPlayerApi player)	Fired when a player respawns
void	OnSpawn()	Fired when a object is spawned via network instantiation
void	OnStationEntered(VRCPlayerApi player)	Requires VRC_Station
void	OnStationExited(VRCPlayerApi player)	Requires VRC_Station
void	OnVideoEnd()	When the video player ends playback
void	OnVideoError(VideoError videoError)	When an error occurs with the player
void	OnVideoLoop()	If looping is enabled, this will fire at the end
void	OnVideoPause()	When the video player is paused
void	OnVideoPlay()	When you start playing a video
void	OnVideoStart()	When a video is playing for the first time?
void	OnVideoReady()	When the video player has loaded the url
void	OnPreSerialization()	Fired before sending network data
void	OnPostSerialization(VRC.Udon.Common.SerializationResult result)	Fired after sending network data and provides data on whether the serialization attempt succeeded and how many bytes were serialized.
void	OnDeserialization()	Fired when network data is received
void	OnPlayerTriggerEnter(VRCPlayerApi player)	Player enters a trigger
void	OnPlayerTriggerStay(VRCPlayerApi player)	Player stays in a trigger
void	OnPlayerTriggerExit(VRCPlayerApi player)	Player leaves a trigger
void	OnPlayerCollisionEnter(VRCPlayerApi player)	Player collides with a collider
void	OnPlayerCollisionStay(VRCPlayerApi player)	Player stays on a collider
void	OnPlayerCollisionExit(VRCPlayerApi player)	Player leaves the collider
void	OnPlayerParticleCollision(VRCPlayerApi player)	A collision particle hits the player
void	MidiNoteOn(int channel, int number, int velocity)	Triggered when a Note On message is received, typically by pressing a key / pad on your device. See Midi in Udon for more information.
void	MidiNoteOff(int channel, int number, int velocity)	Triggered when a Note Off message is received, typically by releasing a key / pad on your device. See Midi in Udon for more information.
void	MidiControlChange(int channel, int number, int value)	Triggered when a control change is received. These are typically sent by knobs and sliders on your Midi device. See Midi Events for more information.
