2.代碼展示

2.1 重點代碼展示

難度選擇模塊

獨立一個窗口控制難度, 通過線程傳參啟動frame窗口

該部分代碼運行結果如下:

圖像繪制模塊

繪制相關圖片

鍵盤監聽模塊

根據玩家操控角色的操作, 判斷是否做出相應的指令

通過對角色當前狀態的屬性進行判定, 以此為依據來控制角色的移動. 以及角色是否處于可站立的位置

地圖移動模塊(只可向右移動)

判定角色在屏幕中所處的位置, 當角色處于屏幕中央位置及向右移動時, 地圖隨之向右移動.

角色死亡后的出生點判斷

角色死亡后將會出生在屏幕最左端的可站立的方塊上

需要對角色位置進行判定的是是否通過移動方塊, 若未通過, 佳能復活在移動方塊左端的方塊之上

角色的死亡判定(碰撞檢測)

private void heroDeathCheck()

{

if ((this.hero.state != 4) && (this.hero.state != 5))

{

for (int i = 0; i < this.enemyBullets.size(); i++)

(b.position.y > this.hero.position.y - this.hero.height / 3) && (b.position.y < this.hero.position.y) &&

(this.hero.visible))

this.hero.state = 4;

if (this.hero.visible) {

this.hero.state = 4;

this.hero.deathEventType = 2;

}

else {

}

}

}

for (int i = 0; i < this.bossChildren.size(); i++)

{

BossChild e = (BossChild)this.bossChildren.get(i);

if ((e.state != 4) && (e.state != 5) &&

(this.hero.position.x > e.position.x - this.hero.width / 2 / 3 - 15.0F) && (this.hero.position.x < e.position.x + 15.0F + this.hero.width / 2 / 3) &&

(this.hero.position.y > e.position.y - 10.0F) && (this.hero.position.y < e.position.y + this.hero.height / 3) &&

(this.hero.visible)) {

this.hero.state = 4;

規定角色可以站立而不死亡的位置

3.代碼改進及任務的分配

3.1

在學習了借鑒的代碼之后, 我們對其進行了一定程度的優化, 增加了一些原來沒有的功能

1.增加了難度的設置, 讓玩家有了更多的選擇

2.使用了緩存的技術, 解決了閃屏的問題

3.增加了角色的死亡位置判定, 使其能在移動方塊左方出生

3.2小組任務分配

沈宇濤: Frame窗口, 繪制動畫, 地圖設定, weapon類

唐洪俊: 人物類設計, 難度調整, 解決Java運行時的閃屏問題

蔡豐駿: Bulet類, 鍵盤監聽, 素材繪制

4.課設總結

Java代碼的團隊合作不同于之前的c, 需要大家的配合, 規范的命名以及寫法, 讓我受益匪淺. 在這次課設中我鍛煉了我自己, 也知道了自己的很多不足, 在編寫的過程之中我們也遇到了很多困難, 在很多我不會的地方, 其他組員也對我伸出了援手. 在共同的努力之下完成了這次的課程設計.
