JAVA实现经典游戏坦克大战代码示例

本篇文章小编给大家分享一下JAVA实现经典游戏坦克大战代码示例，文章代码介绍的很详细，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。

《坦克大战》游戏以坦克战斗为主题，用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。

主要需求

可以生成不同的地图，消灭地图上的所有坦克为胜利；可以设置关卡地图，不断增加难度。

主要设计

1、要有难度关卡：第一关，第二关，第三关，第四关，第五关；第一关地图最简单，第五关地图最难；

2、坦克要有血条，打多次才会死

3、地图要我有我方坦克四辆（相当于4条命）和多辆敌方坦克

4、我方坦克的炮弹数量是固定的，设置为500

5、地图右边显示基本信息

6、地图上要在砖块，铁块，河流

窗口布局

public class GameFrame extends JFrame {

    /**
     * serialVersionUID
     */
    private static final long serialVersionUID = -1176914786963603304L;


    public GameFrame() {
        super();


        this.setSize(800, 700);
        this.setTitle("坦克大战");
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        this.setResizable(false);
        this.setIconImage(TankGameImages.myTankImg[0]);

        // 显示器屏幕大小
        Dimension screenSizeInfo = Toolkit.getDefaultToolkit().getScreenSize();
        int leftTopX = ((int) screenSizeInfo.getWidth() - this.getWidth()) / 2;
        int leftTopY = ((int) screenSizeInfo.getHeight() - this.getHeight()) / 2;

        // 设置显示的位置在屏幕中间
        this.setLocation(leftTopX, leftTopY);
    }

}
