controller.actuators[name] and controller.sensors[name] Made a read-only sequence type for logic brick sensors and actuators which can access single items or be used like a list or dictionary. We could use a python dictionary or CValueList but that would be slower to create. So you can do... for s in controller.sensors: print s print controller.sensors["Sensor"] print controller.sensors[0] sensors = list(controller.sensors) This sequence type keeps a reference to the proxy it came from and will raise an error on access if the proxy has been removed.
