Game Logic (bge.logic)
======================

************
Introduction
************

Module to access logic functions, imported automatically into the python controllers namespace.

.. module:: bge.logic

.. code-block:: python

   # To get the controller thats running this python script:
   cont = bge.logic.getCurrentController() # bge.logic is automatically imported
   
   # To get the game object this controller is on:
   obj = cont.owner

:class:`~bge.types.KX_GameObject` and :class:`~bge.types.KX_Camera` or :class:`~bge.types.KX_LightObject` methods are available depending on the type of object

.. code-block:: python

   # 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 = cont.sensors["sensorname"]

   # To get a sequence of all sensors:
   sensors = co.sensors

See the sensor's reference for available methods:

You can also access actuators linked to the controller

.. code-block:: python

   # To get an actuator attached to the controller:
   #                          +--------+  +-------------------------+
   #                          + Python +--+ Actuator "actuatorname" |
   #                          +--------+  +-------------------------+
   actuator = co.actuators["actuatorname"]
   
   # Activate an actuator
   controller.activate(actuator)

Most logic brick's methods are accessors for the properties available in the logic buttons.
Consult the logic bricks documentation for more information on how each logic brick works.

There are also methods to access the current :class:`bge.types.KX_Scene`

.. code-block:: python

   # Get the current scene
   scene = bge.logic.getCurrentScene()

   # Get the current camera
   cam = scene.active_camera

Matricies as used by the game engine are **row major**
``matrix[row][col] = float``

:class:`bge.types.KX_Camera` has some examples using matrices.

*********
Variables
*********

.. data:: globalDict

   A dictionary that is saved between loading blend files so you can use it to store inventory and other variables you want to store between scenes and blend files.
   It can also be written to a file and loaded later on with the game load/save actuators.

   .. note:: only python built in types such as int/string/bool/float/tuples/lists can be saved, GameObjects, Actuators etc will not work as expected.

.. data:: keyboard

   The current keyboard wrapped in an :class:`~bge.types.SCA_PythonKeyboard` object.

.. data:: mouse

   The current mouse wrapped in an :class:`~bge.types.SCA_PythonMouse` object.

.. data:: joysticks

   A list of attached :class:`~bge.types.SCA_PythonJoystick`.
   The list size is the maximum number of supported joysticks.
   If no joystick is available for a given slot, the slot is set to None.
