|conn||The connection of the client to assign authority to.|
bool True if authority was assigned.
This assigns control of an object to a client via the client's NetworkConnection.
This causes hasAuthority to be set on the client that owns the object, and NetworkBehaviour.OnStartAuthority will be called on that client. This object then will be in the NetworkConnection.clientOwnedObjects list for the connection.
Authority can be removed with RemoveClientAuthority. Only one client can own an object at any time. Only NetworkIdentities with localPlayerAuthority set can have client authority assigned. This does not need to be called for player objects, as their authority is setup automatically.
