飛機大戰
1.主要功能
英雄機受玩家滑鼠控制進行移動并發出子彈對敵人進行攻擊，打中敵機會加分，打中小心心會隨機獲得獎勵，獎勵型別分為三種：英雄機生命值加一，英雄機雙倍火力，英雄機三倍火力（要達到三倍火力首先需要達到雙倍火力才行），當英雄機撞到敵機時，火力加成會消失，當分數達到50的時候會出現boss，boss會進行移動并且發射子彈，擊敗boss會判定游戲勝利，當英雄機撞到敵機，小心心或者被boss發射的子彈擊中時，生命值會減一，當生命值為零的時候會判定游戲失敗，英雄機如果撞到了boss那就直接白給，游戲期間用滑鼠進行控制，點擊滑鼠游戲開始，將滑鼠移動至游戲界面外可以暫停游戲，
2.效果展示圖
3.分析
1. 素材準備
在開發之前需要先去下載一些素材圖片，包括背景圖，英雄機圖，敵機圖，子彈圖，boss圖，開始，暫停，勝利以及結束圖片等，
2.設計構思
- 首先添加開始，勝利，結束等游戲畫面
- 設計獎勵介面以及得分介面添加獎勵與得分的方法
- 設計飛行物父類，在類中添加相關的方法
- 設計敵機類以及小心心類，分別執行得分介面與獎勵介面，并且繼承飛行物父類
- 設計英雄機類，boss類，英雄機子彈類以及boss子彈類分別繼承飛行物父類
- 再設計實作類，對他們進行初始化等操作
- 滑鼠監聽控制英雄機的移動軌跡
3.運用到的知識
- 陣列
- swing組件：圖形界面工具
- 滑鼠監聽
- 面向物件：封裝繼承多型
- ImageIO流
4.代碼展示
測驗類代碼出現了一點小BUG，已經標出，按理來說這樣寫當判定游戲結束或者勝利時會先清理現場，然后再修改為啟動狀態，但是我這個游戲結束后還是戰后現場，界面上boss機發射出來的子彈并不能清除，這就很迷惑，
