Detailed Description

From Wikipedia: "The flippers are one or more small mechanically or electromechanically controlled levers, roughly 3 to 7 cm in length, used for redirecting the ball up the playfield. They are the main control that the player has over the ball. Careful timing and positional control allows the player to intentionally direct the ball in a range of directions with various levels of velocity. With the flippers, the player attempts to move the ball to hit various types of scoring targets, and to keep the ball from disappearing off the bottom of the playfield." CFlipper implements one of those. It's made up of a couple of circles and a couple of line segments that are tangents to both of them.

Constructor & Destructor Documentation

◆ CFlipper()

CFlipper::CFlipper	(	Shapes::CCompoundShape *	p,
		bool	bCCW )

Flippers are compound shapes made up of 2 circles and 2 line segments.

Parameters

p	Pointer to compound shape for flipper.
bCCW	true if counterclockwise is up.

◆ ~CFlipper()

CFlipper::~CFlipper ( )

Delete the instance of Shapes::CCompoundShape pointed to by m_pFlipper.

Member Function Documentation

◆ EnforceBounds()

void CFlipper::EnforceBounds ( )

Enforce bounds on the orientation of flipper, assuming that if it rotates counterclockwise then it is a right flipper, otherwise it is a left flipper.

Here is the caller graph for this function:

◆ Flip()

void CFlipper::Flip ( bool bUp )

If flipper isn't moving up, set its rotational velocity to ROTSPEED (with the correct sign indicating direction),.
