Matlab龙舟游戏
slandarer 人气:0效果图：
没找到合适的背景就自己画了个，大家如果有更好看的可以换一下。。。
步骤
1 创建Axes及图片导入
窗口创建：
Mainfig=figure('units','pixels','position',[50 100 760 400],...
'Numbertitle','off','menubar','none','resize','off',...
'name','dragonBoat');
axes('parent',Mainfig,'position',[0 0 1 1],...
'XLim', [0 760],...
'YLim', [0 400],...
'NextPlot','add',...
'layer','bottom',...
'Visible','on',...
'YDir','reverse',...
'XTick',[], ...
'YTick',[]);
图片导入：
[bkg_C,~,~]=imread('river.png');
[boat_C,~,boat_Alp]=imread('boat.png');
[stone_C,~,stone_Alp]=imread('stone.png');
2 创建timer函数移动背景
DrawBkgHdl=image([0 760],[0 400],bkg_C);
t=0;
tempBkg_C=[bkg_C,bkg_C];
fps = 20;
game = timer('ExecutionMode', 'FixedRate', 'Period',1/fps, 'TimerFcn', @dragongame);
start(game)
function dragongame(~,~)
t=t+6;
modt=mod(t,720);
newBkg_C=tempBkg_C(:,1+modt:684+modt,:);
set(DrawBkgHdl,'CData',newBkg_C)
end
3 绘制石块并移动
其实是5个石块来回变位置，当一个石块位置减小到负数就把数值增加并重新绘制
stonePos=[600;870;1140;1410];
stonePos=[stonePos,randi([90,330],[4,1])];
for i=1:size(stonePos,1)
drawStoneHdl(i)=image([stonePos(i,1)-39 stonePos(i,1)+39],[stonePos(i,2)-20 stonePos(i,2)+20],stone_C,'AlphaData',stone_Alp);
end
function dragongame(~,~)
%这里是之前写的背景部分代码
%。。。。。。。。。。。
%。。。。。。。。。。。
stonePos(:,1)=stonePos(:,1)-20/3;
stonePos(stonePos(:,1)<0,2)=randi([90,330],[1,1]);
stonePos(stonePos(:,1)<0,1)=stonePos(stonePos(:,1)<0,1)+1080;
for ii=1:size(stonePos,1)
set(drawStoneHdl(ii),'XData',[stonePos(ii,1)-39 stonePos(ii,1)+39],...
'YData',[stonePos(ii,2)-20 stonePos(ii,2)+20]);
end
end
4 绘制船并创建鼠标回调
boatPos=[380,200];
DrawBoatHdl=image([boatPos(1)-75 boatPos(1)+75],[boatPos(2)-50 boatPos(2)+50],boat_C,'AlphaData',boat_Alp);
set(gcf,'WindowButtonMotionFcn',@moveBoat,'tag','mov')
function moveBoat(~,~)
xy=get(gca,'CurrentPoint');
temp_y=xy(1,2);
temp_y(temp_y<100)=90;
temp_y(temp_y>340)=330;
boatPos=[380,temp_y];
set(DrawBoatHdl,'YData',[temp_y-50 temp_y+50]);
end
5 碰撞判断函数
function flag=judge(Bpos,Spos)
flag1=abs(Bpos(1)-Spos(:,1))<80;
flag2=abs((Bpos(2)+35)-Spos(:,2))<30;
flag3=flag1&flag2;
flag=any(flag3);
end
dragongame函数做如下改写
function dragongame(~,~)
%这里是之前一大堆代码
%。。。。。。。。。。
%。。。。。。。。。。
%。。。。。。。。。。
if judge(boatPos,stonePos)
stop(game)
set(gcf,'WindowButtonMotionFcn',[]);
text(50,200,'游戏结束','FontSize',54,'Color','w','tag','txt')
end
end

end
set(findobj('tag','txt'),'String',['已前进',num2str(t),'米']);

stop(game)
