/// Using an RPC to Destroy a GameObject is typically a bad idea.
|
||
|
|
/// It allows any player to Destroy a GameObject and may cause errors.
|
||
|
|
///
|
||
|
|
/// A client has to clean up the server's event-cache, which contains events for Instantiate and
|
||
|
|
/// buffered RPCs related to the GO.
|
||
|
|
///
|
||
|
|
/// A buffered RPC gets cleaned up when the sending player leaves the room, so players joining later
|
||
|
|
/// won't get those buffered RPCs. This in turn, may mean they don't destroy the GO due to coming later.
|
||
|
|
///
|
||
|
|
/// Vice versa, a GameObject Instantiate might get cleaned up when the creating player leaves a room.
|
||
|
|
/// This way, the GameObject that a RPC targets might become lost.

///
|
