Constructor & Destructor Documentation

DtSDLGameControllerDevice()

makVre::DtSDLGameControllerDevice::DtSDLGameControllerDevice

(

)

Default constructor.

Initializes the joystick input device

~DtSDLGameControllerDevice()

virtual makVre::DtSDLGameControllerDevice::~DtSDLGameControllerDevice ( )

overridevirtual

Virtual destructor.

Cleans up resources owned by the joystick input device

Member Function Documentation

init()

virtual bool makVre::DtSDLGameControllerDevice::init ( DtVreInputManager & mgr )

overridevirtual

Initialize the joystick input device.

Sets up the joystick device with the input manager and initializes controller tracking structures.

Parameters

mgr	Reference to the input manager that owns this device

Returns

True if initialization succeeded, false otherwise

Implements makVre::DtInputDevice.

shutdown()

virtual void makVre::DtSDLGameControllerDevice::shutdown ( )

overridevirtual

Shut down the joystick input device.

Releases resources and disconnects from any connected controllers

Implements makVre::DtInputDevice.

reportCurrentState()

virtual void makVre::DtSDLGameControllerDevice::reportCurrentState ( )

overridevirtual

Report the current state of all controller inputs.

Sends input events for the current state of all connected controllers' axes, buttons, and hat switches to initialize the input system with current values

Implements makVre::DtInputDevice.

tick()

virtual void makVre::DtSDLGameControllerDevice::tick ( double dt )

overridevirtual

Update method called each frame.

Polls connected controllers for input changes and updates internal state

Parameters

dt	Delta time in seconds since the last frame

Implements makVre::DtInputDevice.

addController()

virtual void makVre::DtSDLGameControllerDevice::addController ( int index )

virtual

Add a controller to be tracked by this device.

Registers a new controller with the specified index and initializes data structures to track its state

Parameters

index

The index of the controller to add

removeController()

virtual void makVre::DtSDLGameControllerDevice::removeController ( int id )

virtual

Remove a controller from being tracked.

Unregisters a controller and removes its tracking data

Parameters

id	The ID of the controller to remove

processInput()

virtual void makVre::DtSDLGameControllerDevice::processInput ( int controller, DtInputType type, int id, float value, int flags = 0 )

virtual

Process input from a controller.

Processes input data from a controller and forwards it to the input manager

Parameters

controller	The index of the controller generating the input
type	The type of input (axis, button, hat, etc.)
id	The specific input ID (button number, axis index, etc.)
value	The input value
flags	Optional flags specific to the input type

processAxisInput()

virtual void makVre::DtSDLGameControllerDevice::processAxisInput ( int controller, int id, int value )

virtual

Process axis input from a controller.

Specialized handling for axis inputs, with additional processing for state tracking and dead zones

Parameters

controller	The index of the controller generating the input
id	The axis index
value	The axis value

getControllerData()

virtual const std::map< int, DtInputData > & makVre::DtSDLGameControllerDevice::getControllerData ( ) const

inlinevirtual

References myControllerData.
