defaultsnakefactory.java

前段时间帮同学写了个简单动画程序：“贪食蛇的原型”

package com.cxlife.snake;

import java.awt.Color;
//蛇体加工厂
public class DefaultSnakeFactory extends SnakeFactory{
   private static Snake snake  = create();
   public  static Snake getInstance(){
     return (Snake)snake.clone();
   }
   private static Snake create(){
     Snake aSnake = new Snake();
     SnakeUnit dsu = new DefaultSnakeUnit();
     dsu.setSnake_color(Color.red);
     aSnake.addUnit(dsu);
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());
     aSnake.addUnit((SnakeUnit)dsu.clone());

     return aSnake;
   }


}
