貪吃蛇 java代碼

自己寫(xiě)著玩的,很簡(jiǎn)單,你試一試哦...

用JAVA設(shè)計(jì)游戲：貪吃蛇游戲

如何用Java語(yǔ)言寫(xiě)一個(gè)貪吃蛇游戲

設(shè)計(jì)游戲，首先就要設(shè)計(jì)界面。首先看一下我設(shè)計(jì)的一個(gè)界面。界面分為左邊的游戲區(qū)與右邊的控制區(qū)。游戲區(qū)包含“得分信息”和貪吃蛇的游戲區(qū)，右邊控制區(qū)有“開(kāi)始”“暫?！薄巴Ｖ埂卑粹o，等級(jí)選擇單選框以及游戲排行榜。

所以我們需要定義swing組件，并在類(lèi)初始化時(shí)初始化這些組件，添加組件。因?yàn)楹竺嬖O(shè)計(jì)游戲的時(shí)候，我們要確切知道游戲區(qū)的大小，所以這里設(shè)置游戲區(qū)固定大小值。本來(lái)想用布局來(lái)更好的管理，但作者對(duì)布局也掌握不夠，所以就先設(shè)置固定大小吧。

定義我們的游戲。貪吃蛇游戲其實(shí)就是包含很多細(xì)小網(wǎng)格，然后蛇在網(wǎng)格中移動(dòng)。蛇由一連串的網(wǎng)格組成，為了視覺(jué)效果，蛇身用藍(lán)色標(biāo)記，食物用紅色標(biāo)記，背景白色。如第一張圖片所示。所以，我們需要定義二維數(shù)組，保存網(wǎng)格信息，保存蛇身和食物的位置信息等。初始化時(shí)，還需要添加鍵盤(pán)事件控制上下左右移動(dòng)。

食物的位置信息是二維的，所以我簡(jiǎn)單定義了一個(gè)類(lèi)用來(lái)保存二維信息。

接著就是實(shí)現(xiàn)游戲的功能了。開(kāi)始，暫停，停止按鈕添加事件控制游戲開(kāi)始。等級(jí)按鈕定義游戲難度等。

開(kāi)始游戲后，我們定義一個(gè)定時(shí)器。蛇身按照指定的方向移動(dòng)，方向是通過(guò)初始化時(shí)添加的鍵盤(pán)事件，鍵盤(pán)的上下左右按鈕來(lái)控制。蛇身是連續(xù)的位置信息，保存到隊(duì)列中，所以蛇身的移動(dòng)就是隊(duì)首增加一個(gè)位置，隊(duì)尾減少位置，然后重新繪畫(huà)游戲區(qū)就可以了。

在蛇身移動(dòng)時(shí)進(jìn)一步做吃掉食物、撞墻、撞到自己的處理。這是游戲的主要邏輯。

最后，游戲結(jié)束我們彈出一個(gè)對(duì)話框提示是否保存游戲得分。我們制作了排行榜信息，只保留前10名的游戲得分。首先定義了一個(gè)實(shí)現(xiàn)Comparable接口的游戲得分類(lèi)，按得分高，時(shí)間最早來(lái)排序。

游戲結(jié)束時(shí)保存得分信息，看是否進(jìn)入到排行榜中。而之前在初始化排行榜組件時(shí)就會(huì)加載游戲排行榜信息。

通過(guò)保存和讀取排行榜信息，我們也熟悉一下文件讀取操作，還有集合、排序算法的功能。
