2、用事件监听。（2） 进入游戏后使用，通过读取文件，读出以前的最好成绩，使用菜单按钮开始游戏（3） 通过方向键来控制潜艇的移动方向，空格键释放鱼雷（4） 击中敌人后加分，同时被敌人击中一次就扣除一次机会，共3次机会2.概要设计2.1程序设计思路此游戏的关键点是潜艇是否被击中的判断，整个屏幕是个二维坐标系，军舰在一个水平位置移动，当在某个位置发射鱼雷，判断鱼雷的图片与不断移动的潜艇图片是否有重合的地方，如果有发生爆炸，如果没有继续移动。2.2程序运行界面2.3 流程图本游戏的基本运行流程是启动后把整个画布作为一个线程，随时准备响应用户按键操作的K响应，100ms扫描一次潜艇和水雷等物体的运行状态。

3、在扫描潜艇和水雷运动时，执行各个物体画面的移动方法。程序并不为每隔新增潜艇和水雷开启一个新线程，太多线程会造成程序的性能直线下降;而是将每一个物体类型直接加入到画布中，每当一个新物体产生，将直接在画布上画出；当物体消除时，将直接在画布上被消除。这样就形成一种注册机制，所有游戏物体的产生和消除都需要画布注册，画布拥有不同类型物体的所有“名单”，所以，当执行移动命令是只需要遍历画布中所有游戏物体，依次执行每隔游戏物体中定义的移动方法即可。3.各模块的功能及程序说明3.1主界面代码主界面设计是使用坐标系，具体实现图如下：public class MainPanel extends JPanel pr
