Documentation for the GameLogic Module.
=======================================

	There are only three importable modules in the game engine:
		- GameLogic
		- L{GameKeys}
		- L{Rasterizer}
	
	All the other modules are accessible through the methods in GameLogic.
	
	See L{WhatsNew} for updates, changes and new functionality in the Game Engine Python API.
	
	Examples::
		# To get a controller:
		import GameLogic
		co = GameLogic.getCurrentController()
		
		# To get the game object associated with this controller:
		obj = co.getOwner()
	L{KX_GameObject} and L{KX_Camera} or L{KX_Light} methods are
	available depending on the type of object::
		# To get a sensor linked to this controller.
		# "sensorname" is the name of the sensor as defined in the Blender interface.
		# +---------------------+  +--------+
		# | Sensor "sensorname" +--+ Python +
		# +---------------------+  +--------+
		sens = co.getSensor("sensorname")
	
		# To get a list of all sensors:
		sensors = co.getSensors()

	See the sensor's reference for available methods:
		- L{KX_NetworkMessageSensor}
		- L{KX_RaySensor}
		- L{KX_MouseFocusSensor}
		- L{KX_NearSensor}
		- L{KX_RadarSensor}
		- L{KX_TouchSensor}
		- L{SCA_KeyboardSensor}
		- L{SCA_MouseSensor}
		- L{SCA_PropertySensor} 
		- L{SCA_RandomSensor} 
	
	You can also access actuators linked to the controller::
		# To get an actuator attached to the controller:
		#                          +--------+  +-------------------------+
		#                          + Python +--+ Actuator "actuatorname" |
		#                          +--------+  +-------------------------+
		actuator = co.getActuator("actuatorname")
		
		# Activate an actuator
		GameLogic.addActiveActuator(actuator, True)
		
	See the actuator's reference for available methods:
		- L{BL_ActionActuator}
		- L{KX_CameraActuator}
		- L{KX_CDActuator}
		- L{KX_ConstraintActuator}
		- L{KX_GameActuator}
		- L{KX_IpoActuator}
		- L{KX_NetworkMessageActuator}
		- L{KX_ObjectActuator}
		- L{KX_SCA_AddObjectActuator}
		- L{KX_SCA_EndObjectActuator}
		- L{KX_SCA_ReplaceMeshActuator}
		- L{KX_SceneActuator}
		- L{KX_SoundActuator}
		- L{KX_TrackToActuator}
		- L{KX_VisibilityActuator}
		- L{SCA_PropertyActuator}
		- L{SCA_RandomActuator} 
	
	There are also methods to access the current L{KX_Scene}::
		# Get the current scene
		scene = GameLogic.getCurrentScene()
		
		# Get the current camera
		cam = scene.active_camera

	Matricies as used by the game engine are B{row major}::
		matrix[row][col] = blah
	L{KX_Camera} has some examples using matricies.
