# 游戏简介 #

大二的时候自己写的一个java小游戏,在游戏中，玩家需要控制上下左右来操作大球吃点比自己小的球，让自己变得更大吃掉更多的小球。

# 项目结构 #

# Direction类 #

枚举类用来标注控制小球的方向

package Ball;
    public enum Direction { 
    	LEFT,
    	UP,
    	RIGHT,
    	DOWN,
    }

# Ball类 #

球类，基本属性包括横纵坐标、直径、颜色。

package Ball;

    public class Ball {

    	private int y;
    	private Color color;
    
    	private int direction=(int) (Math.random()*8+1);
    	
    	public Ball(int diameter, int x, int y, Color color) { 
    		super();
    		this.diameter = diameter;
    		this.x = x;
    		this.y = y;
    		this.color = color;

    	{ 
    		g.setColor(color);
    		g.fillOval(x, y, diameter, diameter);  	
    	}
    	
    	public void move(int m)
    	{ 
    		switch (direction) { 
    		case 1:x-=m;break;//左
    		case 2:x+=m;break;//右
    		case 3:y-=m;break;//上
