In the HealthBar example (Example Central > HealthBar > DamageOnTouch.cs), the Udon script attached to a scene object expects the Player Objects to be available on its Start method, at least the Player Objects for the local player.
The current (2024/10/3) doc describes the "Start event of a Player Object". However, it doesn't explain this precondition for the scripts on scene objects. So, please add some notes.
(I think we need the complete specifications for the lifecycle of Player Objects.)
