Detailed Description

Move a Bitmap from one part of the screen to another.

The speed of movement will be determined by the time limit given to the effect. Only bitmap types with alpha channels should be used, because they will be dragging a block of transparency behind them.

virtual void	run ()
	Runs the effect.
void	param (int x1, int y1, int x2, int y2, const Bitmap &bitmap)
Protected Member Functions

Member Function Documentation

void Effect_move::param (  int  x1, int  y1, int  x2, int  y2, const Bitmap &  bitmap )  [inline]

Parameters: x1,y1  The initial coordinates x2,y2  The final coordinates bitmap  The bitmap to be moved.

void Effect_move::run (   )  [virtual]

Runs the effect. It takes no parameters because it should be possible to run an effect without knowing its type, only knowing how long it will take. It should be possible to call run() more than once. Implements Effect.

void Effect_move::step (  int  value  )  [protected, virtual]

A callback method that's called by animate() every frame. That means it shouldn't take long to execute. Before animate() calls step() it sets Effect::_oldval to what value was at the last call. Implements Effect.
