用Java编写的贪吃蛇游戏.docx

1、用Java编写的贪吃蛇游戏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XX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

2、的代码中修改后面的值就可以了。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 nodeHeig

3、th = 20;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netbeansIDE6.9.1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:Greedsnake、Node、SnakeModel.(1Greensnake.javaimport java.awt.*;import java.awt.event.*;import java.util.*;import javax.swing.*;/* author :1袏掱惢1public class Gr
