Module to access logic functions, imported automatically into the python controllers namespace.
# 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
KX_GameObject and KX_Camera or KX_LightObject 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 = 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
# To get an actuator attached to the controller:
# +--------+ +-------------------------+
# + Python +--+ Actuator "actuatorname" |
# +--------+ +-------------------------+
actuator = co.actuators["actuatorname"]
# Activate an actuator
controller.activate(actuator)
See the actuator’s reference for available methods
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 bge.types.KX_Scene
# 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
bge.types.KX_Camera has some examples using matrices.
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.

Restarts the current game by reloading the .blend file (the last saved version, not what is currently running).
Converts the all of the datablocks of the given type from the given blend.
| Parameters: |
|
|---|---|
| Return type: |
Note
Asynchronously loaded libraries will not be available immediately after LibLoad() returns. Use the returned KX_LibLoadStatus to figure out when the libraries are ready.
Uses existing datablock data and loads in as a new library.
| Parameters: |
|
|---|
Frees a library, removing all objects and meshes from the currently active scenes.
| Parameters: | name (string) – The name of the library to free (the name used in LibNew) |
|---|

|---|
Sends a message to sensors in any active scene.
| Parameters: |
|
|---|

Render next frame (if Python has control)
Converts a blender internal path into a proper file system path.
Use / as directory separator in path You can use ‘//’ at the start of the string to define a relative path; Blender replaces that string by the directory of the current .blend or runtime file to make a full path name. The function also converts the directory separator to the local file system format.
| Parameters: | path (string) – The path string to be converted/expanded. |
|---|---|
| Returns: | The converted string |
| Return type: | string |

| Parameters: | path (string) – Optional directory argument, will be expanded (like expandPath) into the full path. |
|---|---|
| Returns: | A list of filenames, with no directory prefix |
| Return type: | list |
Returns a random floating point value in the range [0 - 1)
