2、采用事件監(jiān)聽。（2） 進(jìn)入游戲后使用，通過讀取文件，讀出以前的最好成績(jī)，使用菜單按鈕開始游戲（3） 通過方向鍵來(lái)控制潛艇的移動(dòng)方向，空格鍵釋放魚雷（4） 擊中敵人后加分，同時(shí)被敵人擊中一次就扣除一次機(jī)會(huì)，共3次機(jī)會(huì)2.概要設(shè)計(jì)2.1程序設(shè)計(jì)思路此游戲的關(guān)鍵點(diǎn)是潛艇是否被擊中的判斷，整個(gè)屏幕是個(gè)二維坐標(biāo)系，軍艦在一個(gè)水平位置移動(dòng)，當(dāng)在某個(gè)位置發(fā)射魚雷，判斷魚雷的圖片與不斷移動(dòng)的潛艇圖片是否有重合的地方，如果有發(fā)生爆炸，如果沒有繼續(xù)移動(dòng)。2.2程序運(yùn)行界面2.3 流程圖本游戲的基本運(yùn)行流程是啟動(dòng)后把整個(gè)畫布作為一個(gè)線程，隨時(shí)準(zhǔn)備響應(yīng)用戶按鍵操作的K響應(yīng)，100ms掃描一次潛艇和水雷等物體的運(yùn)行狀態(tài)

3、。在掃描潛艇和水雷運(yùn)動(dòng)時(shí)，執(zhí)行各個(gè)物體畫面的移動(dòng)方法。程序并不為每隔新增潛艇和水雷開啟一個(gè)新線程，太多線程會(huì)造成程序的性能直線下降;而是將每一個(gè)物體類型直接加入到畫布中，每當(dāng)一個(gè)新物體產(chǎn)生，將直接在畫布上畫出；當(dāng)物體消除時(shí)，將直接在畫布上被消除。這樣就形成一種注冊(cè)機(jī)制，所有游戲物體的產(chǎn)生和消除都需要畫布注冊(cè)，畫布擁有不同類型物體的所有“名單”，所以，當(dāng)執(zhí)行移動(dòng)命令是只需要遍歷畫布中所有游戲物體，依次執(zhí)行每隔游戲物體中定義的移動(dòng)方法即可。 3.各模塊的功能及程序說(shuō)明3.1主界面代碼主界面設(shè)計(jì)是使用坐標(biāo)系，具體實(shí)現(xiàn)圖如下：public class MainPanel extends JP
