面向对象程序设计实训（吃金豆游戏设计与实现）(6)

Cell -r,c,w,h:int +draw(Graphics g):void +abstract drawImage(Graphics g,int x,int y):void Pacman Monster Block +abstract IsReachable():bool +abstract IsEatable():bool

Bean Wall

说明：Pacman的Move()方法的算法思路 If(isRunning){

取下一个Block ->nextBlock;

If(nextBlock.IsReachable()&&nextBlock.IsEatable()){ nextBlock的r,c ->当前r,c; nextBlock置为White; 加分;

金豆数减一

}else if(nextBlock.IsReaable()){ nextBlock的r,c ->当前r,c;

}else{

White isRunning = false; }

}
