Java 貪吃蛇報(bào)告

1、Java高級(jí)編程課程報(bào)告第xx小組：貪吃蛇游戲項(xiàng)目小組成員及分工姓名角色負(fù)責(zé)功能組長(zhǎng)設(shè)計(jì)與編碼測(cè)試 主要完成模式選擇窗口和游戲主窗口菜單欄下拉菜單的設(shè)計(jì)與程序編寫(xiě)，貪吃蛇游戲界面布局，游戲的操作步驟設(shè)計(jì)。程序的調(diào)試 主要完成游戲主窗口的設(shè)計(jì)與編程，設(shè)計(jì)貪吃蛇的移動(dòng)方向鍵設(shè)置，得分規(guī)則等，以及最后程序的調(diào)試。 主要完成主菜單窗口的設(shè)計(jì)和程序編寫(xiě)，界面的設(shè)計(jì)布局，游戲主窗口界面背景設(shè)置，按鈕的圖片設(shè)置等。一、 實(shí)驗(yàn)環(huán)境操作系統(tǒng)：Windows 7編程環(huán)境：Eclipse、JDK二、 實(shí)驗(yàn)內(nèi)容與完成情況（主要介紹項(xiàng)目總體功能分析與說(shuō)明。）貪吃蛇小游戲的JAVA程序是利用上 、下 、左、右 方向鍵來(lái)改

2、變蛇的運(yùn)動(dòng)方向，按空鍵暫停游戲，按enter鍵重新開(kāi)始。長(zhǎng)按某個(gè)方向鍵后，蛇的運(yùn)動(dòng)速度會(huì)加快，在隨機(jī)的地方產(chǎn)生食物，吃到食物就變成新的蛇體，碰到壁或自身則游戲結(jié)束，否則正常進(jìn)行游戲。以不同的速度和不同方向吃到食物所獲得的分?jǐn)?shù)也不相同。窗口功能說(shuō)明：設(shè)計(jì)了三個(gè)窗口，分別是游戲主窗口，主菜單窗口，模式選擇窗口。 菜單欄分別為：游戲菜單（重新開(kāi)始）和幫助菜單以及返回（返回主菜單） 。其中，按返回菜單按鈕后會(huì)顯示主菜單，其包括游戲開(kāi)始、設(shè)置、退出游戲三項(xiàng)按鈕選擇；如果按“設(shè)置”按鈕會(huì)進(jìn)入“模式選擇”窗口。而模式選擇窗口菜單包括了初級(jí)、中級(jí)、高級(jí)、返回按鈕。1、功能1（主菜單窗口）（

3、1） 主菜單窗口主要是提供“游戲開(kāi)始”、“設(shè)置”和“退出”按鈕。“游戲開(kāi)始”按鈕按下后會(huì)進(jìn)入“游戲主窗口”開(kāi)始游戲； “設(shè)置”按鈕是調(diào)用“模式選擇”窗口對(duì)游戲貪吃蛇的速度進(jìn)行設(shè)置； “退出”按鈕按下則會(huì)直接退出游戲。（2） 功能1實(shí)現(xiàn)的流程圖實(shí)現(xiàn)的效果圖如下：（3） 功能1（主菜單窗口）代碼：package Swing;import java.awt.Color;import java.awt.EventQueue;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.
