飛機大戰的需求:

? 1.游戲可以產生: 小敵機/大敵機/小蜜蜂 -> 隨機(概率)產生
? 2.跟鼠標相關的操作:
? a.自己的飛機移動
? b.點擊開始游戲
? c.鼠標移出窗口,游戲暫停
? d.鼠標進入窗口,游戲繼續
? 3.子彈打中小敵機: 分數 + 5
? 4.子彈打中大敵機: 分數 + 50,獎勵(雙倍火力,生命值加成) - 接口
? 5.子彈打中小蜜蜂: 獎勵(雙倍火力,生命值加成)

API(application programming Interface): 應用程序接口
幫助文檔

System -> java.lang
Arrays -> java.utils
Math -> java.lang
構造方法 方法

1.java.awt javax.swing - 窗口化界面

? Frame -> JFrame : 窗口類

DO_NOTHING_ON_CLOSE:關閉時什么都不做 HIDE_ON_CLOSE:關閉時隱藏窗口(默認效果) DISPOSE_ON_CLOSE:關閉時注銷窗口 EXIT_ON_CLOSE:關閉時退出程序什么時候使用靜態常量:如果是只判斷兩種情況: boolean如果是一開始就固定好幾種狀態: final一般會使用int類型修飾,因為浮點型不能判斷兩個值是否相等

2.畫板類:

? Panel -> JPanel -> 解決閃屏問題

原生的 JPanel 是不能自定義繪畫的 只能畫 按鈕,輸入框...等的一些組件 功能增強 -> 自定義類繼承JPanel因為子類更能一定比父類更強大

3.加載圖片

? 1)圖片是存在磁盤中,要將此文件加載到JVM內存中
? I0 -> 輸入/輸出流

new File("相對路徑") - 工程下文件必須存在:和類同包下ImageDemo.class -> 獲取類的字節碼文件對象ImageDemo.class.getResource()ImageDemo.class.getResourceAsStream() - 獲取資源文件流文件必須存在src下:ImageDemo.class.getClassLoader()

4.程序設計 - 類的設計

? 對象: 小飛機/大飛機/小蜜蜂/英雄機/子彈

父類(基類):抽象類成員變量:int blood int x int y 圖片圖片寬/ 高成員方法:move() -> 抽象方法 -> 中文對象對應的類: 子類 extends 父類:小飛機:成員變量:int blood int score int x int y 圖片圖片寬/ 高 int speed成員方法:move()大飛機成員變量:int blood int score int x int y 圖片圖片寬/ 高 int speed成員方法:move()小蜜蜂成員變量:int blood int x int y 圖片圖片寬/ 高 int speed成員方法:move()英雄機成員變量:int blood int x int y 圖片圖片寬/ 高 子彈成員方法:move()子彈成員變量:int blood int x int y 圖片圖片寬/ 高 int speed成員方法:move()構造方法:

5.存很多數據 -> 數組:

? 1.數組長度不可變的,如果想給數組擴容,就必須使用到數組的復制
? 方法的復制:
? 1).最原始的方式
? 2).Arrays.copyOf()
? 3).System.arrayCopy()

2.數組只能存放同種類型的數據基本數據類型:int[] = {1,2,3,4}引用數據類型Student[] = new Student[5];

ArrayList: 可變長數組
1.只能存放引用數據類型數組
int -> Integer (包裝類)
char -> Character
byte -> Byte
long -> Long

2.可以存所有類型,但是建議存同一種類型,因為有可能出現類型轉換異常泛型:<E> -> E表示Object,所有類型3.構造方法:空參構造方法: 沒有內容的集合ArrayList list = new ArrayList();常用方法API:void add(Object obj)void add(int index, Object obj)Object get(int index)Obejct remove(int index)

具體步驟：

1.創建窗口對象
2.創建畫板對象
3.類的設計 - 確定類中目前需要的成員變量和成員方法
4.成員方法目前只有一個 - move(), 研究不同類的移動方式
5.創建類需要不同的構造方法 - 初始化成員變量
a.加載(讀取)圖片 -> static{} -> 靜態代碼塊,需要靜態成員變量
b.獲取父類中的成員變量
1.如果父類中的成員變量是protected修飾的
那么子類可以直接獲取
2.如果父類中的成員變量是private修飾的
通過調用父類的有參構造方法super()

6.主程序: 添加定時器
a.生成所有飛行物
b.所有飛行物的移動
c.生成很多子彈
d.所有子彈的移動
e.判斷所有飛行物 和子彈的越界
f.判斷子彈和飛行物的碰撞
g.判斷飛行物和英雄機的碰撞
h.英雄的移動 - 鼠標監聽
MouseListener - 接口
MouseMotionListener - 接口
鼠標適配器 -> new MouseAdapter
i.判斷游戲是否結束 -> blood == 0

7.添加鼠標監聽 - 接口

8.游戲狀態的判斷 -> 結合鼠標適配器完成
//靜態常量 -> 全大寫

開始狀態 -> START 運行狀態 -> RUNNING 暫停狀態 -> PAUSE 死亡狀態 -> GAME_OVER//當前狀態 - 會改變 -> 變量 int start = START;START -> 單擊 -> RUNNING RUNNING -> 移出 -> PAUSEgetBlood == 0 -> GAME_OVER PAUSE -> 進入 -> RUNNING GAME_OVER -> 單擊START 如果只要兩個狀態 -> Boolean 使用int類型存儲 -> 判斷值是否相等

9.碰撞
判斷子彈和飛行物的碰撞
小蜜蜂/大敵機/小敵機 -> 向上造型fyings
判斷飛行物和英雄機的碰撞

10.添加獎勵 [雙倍火力/ 生命值加成]

11.判斷游戲結束 -> hero.blood == 0

12.灰燼 -> 和父類是不同的類
