用Java编写的贪吃蛇游戏.

1、贪吃蛇游戏的制作里面还有一些代码还没有完善，比如说:没有开始的控制，当玩家一进去游戏就自 动开始了，并且当玩家同时点击方向键的上键和左键游戏就会中断，这些仅仅是我在测试的时候发现的，也许还有更多的错误，见谅!我会在最近更新的，然后上传到我的 百度账号里面的。当然，这个游戏里面的界面的大小和颜色也许不是你所喜欢的，但是你可以修改的，具体的修改方法如下：1、修改界面的大小在 GreenSnake类中，public static final int canvasWidth = 1400;public static final int canvasHeigth = 1500;在上面的代码中修改后面的值

2、就可以了。2、修改界面的颜色也是在 GreenSnake类中,g.setColor(Color.GREEN;修改color后面颜色就可以了，(这里说明一下：你可以将color后面的逗号去掉，然后重新输入一个，后面就自动会弹出很多的颜色，你可以在里面选择一个自己喜欢的颜色3、修改蛇的食物的颜色也是在 GreenSnake类中,g.setColor(Color.RED;方法和修改界面的颜色一样4、修改蛇身的大小也是在 GreenSnake类中,public static final int nodeWidth = 20;public static final int nodeHeigth = 20

3、;修改以上代码的值就可以了。贪吃蛇游戏的制作：这里我用到的是netbeanslDE6.9.1这个软件制作的：1、首先点击/文件/,创建一个新的项目,名称叫snake;2、在这个项目下创建一个新的包，取名叫snake;3、 最后就是需要在这个包里面创建3个类，这3个类分别为:GreedsnakeNode、SnakeModel.(1Gree nsn ake.javaimport java.awt.*;import java.awt.eve nt.*;import java.util.*;import javax.swi ng.*;/* author :1 袏掱惢 1public class Gre
