Basic課程設(shè)計(jì)報(bào)告題目1： 貪吃蛇 難度：**** 題目2： 難度： 指導(dǎo)教師：姓 名： 學(xué) 號(hào)： 專 業(yè)： 班 級(jí)： 學(xué) 院：日 期：目錄題目簡(jiǎn)介...................................................................................................錯(cuò)誤！未定義書簽。當(dāng)蛇的頭撞到障礙物時(shí)或碰到自己身體時(shí)，游戲結(jié)束。如果運(yùn)動(dòng)過(guò)程中，其頭部碰到障礙物或自己，則被撞死，游戲結(jié)束。圖5 為了使效果更好，我加了背景音樂(lè)和速度控制。首先我們要將背景網(wǎng)格和蛇身畫出來(lái)，由于受到了動(dòng)態(tài)添加控件的啟發(fā)，我用了powerpacks中的ovalshape來(lái)構(gòu)造蛇身，lineshape來(lái)構(gòu)造線，為了滿足蛇的身體長(zhǎng)長(zhǎng)，用到了數(shù)組。蛇的身體Public word(4)As LabelImports Public a(num)As OvalShape ‘a(chǎn)（）為定義蛇身的數(shù)組，變量num用來(lái)記錄蛇身個(gè)數(shù)Public line(41)As LineShape Dim canvas = New For i = 4 To 0 Step1 a(i)= New OvalShapea(i).Size = New Size(20, 20)a(i).Top = 360 a(i).Left = 120 + 20 * i a(i).FillStyle = a(i).FillColor = a(i).Parent = canvas Nexta(0).FillColor = ‘給蛇上色 a(0).BackColor = Dim i As Integer = For i = 0 To 20 39。由此可以用以下代碼解決：Private Sub form_keydown(ByVal sender As Object, ByVal e As )Handles Select Case Case 37 If d 2 Then d = 0 ‘這樣能讓蛇不往回走Case 38 If d 1 Then d = 3 Case 39 If d 0 Then d = 2 Case 40 If d 3 Then d = 1 End SelectEnd Sub Select Case d Case 2 For i = num To 1 Step1 a(i).Left = a(i1).Top Nexta(0).Left += 20 Case 1 For i = num To 1 Step1 a(i).Left = a(i1).Top Nexta(0).Top += 20 Case 0 For i = num To 1 Step1a(i).Left = a(i1).Top Nexta(0).Left= 20 Case 3 For i = num To 1 Step1 a(i).Left = a(i1).Top Nexta(0).Top= 20 End Select 然后我們可以來(lái)設(shè)置食物來(lái)讓蛇吃，我用rectangleshape控件來(lái)制造食物，就像和畫出蛇身一樣寫，但是每當(dāng)被吃后它有出現(xiàn)，而且不能出現(xiàn)在蛇身上。 Chr(13)amp。 _ Int(gameinterval * gametime / 1000)amp。 ”請(qǐng)留下大名“, ”貪吃蛇“, ”無(wú)名氏“)Elsep = MsgBox(”Do you want to continue?“, vbYesNo, ”生命值“ amp。 Int(score)amp。” amp。主要代碼如下：FileOpen(1, filelacation, )39。因此方便好多。()()End IfEnd Sub End Class[設(shè)計(jì)】此窗體用來(lái)調(diào)節(jié)蛇運(yùn)動(dòng)的快慢程度。，了解了鍵盤下所代表的代碼意義，之前一直使用的是select case keycode代碼，怎么也無(wú)法使其響應(yīng)。，解決的辦法就是不斷的進(jìn)行調(diào)試，修改。 在定義變量時(shí)我盡量定義其為全局變量和模塊級(jí)變量。 我想在游戲中添加一些音樂(lè)，并且用到了循環(huán)播放的代碼，但是至今我還是沒(méi)有想到如何能將播放中的音樂(lè)暫停。 當(dāng)我運(yùn)行程序時(shí)，如果我點(diǎn)了界面上的某條線的話，蛇就不再響應(yīng)鍵盤事件了，必須使用ctrl+方向鍵才能使其響應(yīng)鍵盤事件。這段時(shí)間，常會(huì)向同學(xué)請(qǐng)教，也自覺(jué)地去借了些書看看，基本上完成了要求，但是功能、界面都還不是很完善，我會(huì)借助以后的時(shí)間繼續(xù)去加工的，我需要的是學(xué)以致用。這就是2個(gè)月的課程設(shè)計(jì)所教會(huì)我的。Close
