課程設(shè)計(jì)

平臺(tái)：matlab GUIDE

功能實(shí)現(xiàn)：掃雷游戲

目的：

1.熟悉matlab基本的代碼編寫能力；
2.學(xué)會(huì)利用matlab GUI設(shè)計(jì)圖形交互界面，方便使用者操作；

演示：

1.創(chuàng)建15行×20列的掃雷界面,界面上包括棋子數(shù)量統(tǒng)計(jì)和炸彈數(shù)量設(shè)置.炸彈數(shù)量越多,掃雷難度越大.

2. 正常掃雷演示:

3. 點(diǎn)擊到炸彈后,彈出對(duì)話框,可選擇關(guān)閉程序或者重新開始.

代碼示例：

每個(gè)按鈕被點(diǎn)擊后執(zhí)行的回調(diào)函數(shù)：

function pushcallback(hObject, eventdata, handles)
global row col mines times flags mine control around  Tags Bombs
a = get(hObject,'position');
hang=double((a(2)-0.86)/(-0.054))-0.0001;
lie=double((a(1)-0.013)/0.045)-0.0001;
place=ceil([hang,lie]);
if times==1
    mines=str2num(get(handles.edit1,'string'));
    set(handles.edit1,'enable','off')
    first_time(hObject, eventdata, handles,place)
    times=0;
end
%如果點(diǎn)到了炸彈
if mine(place(1),place(2))==1&&~isequal(get(hObject,'CData'),Tags)
    [p,q]=find(mine==1);
    bombs=p+row*(q-1);
    set(handles.h(bombs),'CData',Bombs,'ForegroundColor','k','backgroundcolor',0.85*[1,1,1]);
    set(hObject,'CData',imread('爆炸圓.png'),'ForegroundColor','k','backgroundcolor',0.85*[1,1,1]);
    buttonName2=questdlg('很遺憾，你輸了','游戲結(jié)束','close','restart','close');
    if isempty(buttonName2)
       close;
       return
    end
    if strcmp(buttonName2,'restart')
        set(handles.edit1,'enable','on')
        set(handles.text1,'string','標(biāo)記：')
        mines=35;%炸彈總數(shù)
        times=1;
        flags=0;
        for m=1:row
            for n=1:col
                set(handles.h(m,n),'style','pushbutton','foregroundColor',0.7*[1 1 1],...
                    'BackgroundColor',0.7*[1 1 1],'CData',[]);
            end
        end
        mine=zeros(row,col);
        control=ones(row,col);
        around=zeros(row,col);
           return
    else
        if strcmp(buttonName2,'close')
            close;
            return
        end
    end
end
%如果點(diǎn)到的不是炸彈，但是其九宮格內(nèi)有炸彈的話，只翻當(dāng)前點(diǎn)擊的該格子
if (mine(place(1),place(2))==0)&&(around(place(1),place(2))~=0)&&~isequal(get(hObject,'CData'),Tags)
    drawnum(hObject, eventdata, handles,place)
end
%如果點(diǎn)到的不是炸彈，而且其九宮格內(nèi)也沒有炸彈的話，就隨機(jī)擴(kuò)展當(dāng)前點(diǎn)擊的格子周邊的連接的不是炸彈的多個(gè)格子
if (mine(place(1),place(2))==0)&&(around(place(1),place(2))==0)&&~isequal(get(hObject,'CData'),Tags)
    begins=place;
    [whitea,whiteb]=find(around==0);
    white=[whitea,whiteb];
    next=[begins;begins+[1,0];begins+[-1,0];begins+[0,1];begins+[0,-1]];
    while ~isempty(intersect(white,next,'rows'))
        [a,b,~]=intersect(white,next,'rows');
        begins=[a;begins];
        white(b,:)=[];
        ad=length(sum(begins,2));
        next=[begins;begins+ones(ad,1)*[1,0];begins+ones(ad,1)*[-1,0];begins+ones(ad,1)*[0,1];begins+ones(ad,1)*[0,-1]];
    end
    drawbegins=begins(:,1)+row*(begins(:,2)-ones(ad,1));
    set(handles.h(drawbegins),'style','text','string','','backgroundcolor',0.85*[1,1,1]);
    control(drawbegins)=0;
    colors=[begins;begins+ones(ad,1)*[1,0];begins+ones(ad,1)*[-1,0];begins+ones(ad,1)*[0,1];begins+ones(ad,1)*[0,-1];
        begins+ones(ad,1)*[1,1];begins+ones(ad,1)*[1,-1];begins+ones(ad,1)*[-1,1];begins+ones(ad,1)*[-1,-1]];
    colors=unique(colors,'rows');
    [txa,txb]=find(around~=0);
    tx=[txa,txb];
    txcolors=intersect(tx,colors,'rows');
    for i=1:length(sum(txcolors,2))
        drawnum(handles.h(txcolors(i,1),txcolors(i,2)),eventdata, handles,txcolors(i,1:2))
    end
