| conn | Connection which is adding the player. |
| player | Player object spawned for the player. |
| playerControllerId | The player controller ID number as specified by client. |
bool True if player was replaced.
This replaces the player object for a connection with a different player object. The old player object is not destroyed.
If a connection already has a player object, this can be used to replace that object with a different player object. This does NOT change the ready state of the connection, so it can safely be used while changing scenes.
