Avatar Events

These events allow Udon to react to changes regarding player avatars.

OnAvatarChanged

Returns VRCPlayerApi object for the instigating player. Called when a player's avatar has finished loading.

Persisted eye heights

Players will sync any variance from their prefab eye height after their avatar loads, triggering an OnAvatarEyeHeightChanged event.

If the VRCPlayerApi object is for the local player, retrieving its eye height will return the prefab height during this event.

If the VRCPlayerApi object is for a remote player, be aware that the remote player may not have synced their new eye height yet, and you should not rely on the returned value in this case.

OnAvatarEyeHeightChanged

Returns a VRCPlayerApi object for the instigating player and a float describing their previous or previously synced eye height in meters. Called when a player has their eye height change via switching to another avatar or via the avatar scaling system.

First avatar load

When a local or remote user joins a world, the first previous eye height value received for that user may be 0.

Avatar changes, remote players, and event ordering

When a local user changes their avatar and applies a persisted eye height (if they have one saved that differs from their prefab height), this event should only execute for their persisted height.

When a remote user changes their avatar and applies a persisted eye height (if they have one saved that differs from their prefab eye height), this event may execute more than once.

For remote players, you will receive this event every time a new eye height is synced to you by the remote player. This means that you could receive an OnAvatarEyeHeightChanged event prior to an OnAvatarChanged event, but you should not receive OnAvatarEyeHeightChanged events out of order.
