virtual void initialise (RenderWindow *pWindow, bool useKeyboard=true, bool useMouse=true, bool useGameController=false)
 
Note:
Only keyboard and mouse currently implemented.
Parameters:
pWindow The window to capture input for
useKeyboard If true, keyboard input will be supported.
useMouse If true, mouse input will be supported.
useGameController If true, joysticks/gamepads will be supported.


virtual void capture ()
 
Remarks:
This method captures the state of all input devices and stores it internally for use when the enquiry methods are next called. This is done to ensure that all input is captured at once and therefore combinations of input are not subject to time differences when methods are called.

Note:
In immediate mode, this enquiry method uses the state of the keyboard at the last 'capture' call.


void mouseMoved ()
 Creates mouse moved or dragged events depending if any button is pressed.

void createMouseEvent (int id, int button)
 Creates a MouseEvent that first gets processed by the cursor, then gets pushed on the queue.

void triggerMouseButton (int nMouseCode, bool mousePressed)
 Creates mouse pressed, released, and clicked events.

void createKeyEvent (int id, int key)

The default behaviour of the input reader is simply to capture the current state of the mouse / keyboard on demand. An alternative is to use buffered input where all events are registered on a queue.
