class PygameSocketGame(PygameGame):
"""
PygameSocketGame uses the main_loop() from PygameGame
to get all pygame event handling. It overrides the
generate_external_events() method to add in socket
message processing. This means the sockets are not
event driven, but poll driven, with polls at the frame
rate of pygame. It uses a ClientGameSocket object
to manage all server communications.
Methods:
get_sock()
set_engine(engine)
connect_to_server()
disconnect_from_server()
generate_external_events()
