1.課設(shè)課題

組長: 沈宇濤

組員: 唐洪俊, 蔡豐駿

1.1 基于java swing開發(fā)的魂斗羅

可實(shí)現(xiàn)的功能: 人物的移動(dòng)射擊以及跳躍

人物武器的切換

人物的死亡與重生

敵人的行為設(shè)定

1.2 UML設(shè)計(jì)圖

1.3 程序運(yùn)行展示

uploading-image-813493.png

2.代碼展示

2.1 重點(diǎn)代碼展示

難度選擇模塊

獨(dú)立一個(gè)窗口控制難度, 通過線程傳參啟動(dòng)frame窗口

該部分代碼運(yùn)行結(jié)果如下:

圖像繪制模塊

繪制相關(guān)圖片

鍵盤監(jiān)聽模塊

根據(jù)玩家操控角色的操作, 判斷是否做出相應(yīng)的指令

角色的移動(dòng)

通過對角色當(dāng)前狀態(tài)的屬性進(jìn)行判定, 以此為依據(jù)來控制角色的移動(dòng). 以及角色是否處于可站立的位置

地圖移動(dòng)模塊(只可向右移動(dòng))

判定角色在屏幕中所處的位置, 當(dāng)角色處于屏幕中央位置及向右移動(dòng)時(shí), 地圖隨之向右移動(dòng).

角色死亡后的出生點(diǎn)判斷

角色死亡后將會(huì)出生在屏幕最左端的可站立的方塊上

需要對角色位置進(jìn)行判定的是是否通過移動(dòng)方塊, 若未通過, 佳能復(fù)活在移動(dòng)方塊左端的方塊之上

角色的死亡判定(碰撞檢測)

規(guī)定角色可以站立而不死亡的位置

3.代碼改進(jìn)及任務(wù)的分配

3.1

在學(xué)習(xí)了借鑒的代碼之后, 我們對其進(jìn)行了一定程度的優(yōu)化, 增加了一些原來沒有的功能

1.增加了難度的設(shè)置, 讓玩家有了更多的選擇

2.使用了緩存的技術(shù), 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(dòng)方塊左方出生

3.2小組任務(wù)分配

沈宇濤: Frame窗口, 繪制動(dòng)畫, 地圖設(shè)定, weapon類

唐洪俊: 人物類設(shè)計(jì), 難度調(diào)整, 解決Java運(yùn)行時(shí)的閃屏問題

蔡豐駿: Bulet類, 鍵盤監(jiān)聽, 素材繪制

4.課設(shè)總結(jié)

Java代碼的團(tuán)隊(duì)合作不同于之前的c, 需要大家的配合, 規(guī)范的命名以及寫法, 讓我受益匪淺. 在這次課設(shè)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(huì)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(shè)計(jì).

總結(jié)
