Function Documentation

WiiController_ButtonHeld()

bool WiiController_ButtonHeld	(	WiiController *	controller,
		int	buttonEnum
	)

Tells if a button is down.

Parameters

buttonEnum

The button to query.

Returns

True if the given button was pressed down this frame or before.

WiiController_ButtonPress()

bool WiiController_ButtonPress	(	WiiController *	controller,
		int	buttonEnum
	)

Tells if a button was pressed down this frame.

Parameters

buttonEnum

WiiController_ButtonRelease()

bool WiiController_ButtonRelease	(	WiiController *	controller,
		int	buttonEnum
	)

Tells if a button was released this frame.

Parameters

buttonEnum

The button to query.

Returns

True if the given button was released this frame.

WiiController_GetCursorPosition()

vec2 WiiController_GetCursorPosition

(

WiiController *

controller

)

Returns the position of the cursor.

Returns

Position of the cursor in pixels.

WiiController_GetNunchukJoystickDirection()

vec2 WiiController_GetNunchukJoystickDirection

(

WiiController *

controller

)

Returns the direction of the nunchuck joystick.

Note

The returned vector2 is not normalized.

Returns

Direction of the nunchuck joystick.

WiiController_GetPitch()

float WiiController_GetPitch

(

WiiController *

controller

)

Returns the pitch reported by the gyroscope in radians.

Returns

Amount of pitch in radians [-Pi, Pi]. 0 means no roll.

WiiController_GetRoll()

float WiiController_GetRoll

(

WiiController *

controller

)

Returns the roll reported by the gyroscope in radians.

Returns

Amount of roll in radians [-Pi, Pi]. 0 means no roll.

WiiController_GetYaw()

float WiiController_GetYaw

(

WiiController *

controller

)

Returns the yaw reported by the gyroscope in radians.

Returns

Amount of yaw in radians [-Pi, Pi]. 0 means no roll.

WiiController_Init()

void WiiController_Init	(	WiiController *	controller,
		u8	channel
	)

Initialize a controller and set a channel for it.

Parameters

channel

Channel of the controller. Valid values [0,3]

WiiController_StartFrame()

void WiiController_StartFrame

(

WiiController *

controller

)

Prepares controller for input.

Releases all buttons and clears the list of released buttons. Call this before any input and code that reads controller state.

WiiController_ZeroAllInputs()

void WiiController_ZeroAllInputs

(

WiiController *
