如何利用Matlab制作一款真正的拼图小游戏
效果：
简单原理介绍：
1构造0,1矩阵作为每片拼图的透明度，可以构造出不规则形状的拼图(image函数有alphaData属性可以设置)
jigsawMask=zeros(101*5,101*5); jigsawMask(102:404,102:404)=1; [xMesh,yMesh]=meshgrid(1:101*5,1:101*5); dis1=sqrt((xMesh-51).^2+(yMesh-253).^2); dis2=sqrt((xMesh-505+50).^2+(yMesh-253).^2); dis3=sqrt((xMesh-253).^2+(yMesh-152).^2); dis4=sqrt((xMesh-253).^2+(yMesh-505+151).^2); bool1=dis1<=50; bool2=dis2<=50; bool3=dis3<=50; bool4=dis4<=50; jigsawMask(bool1)=1; jigsawMask(bool2)=1; jigsawMask(bool3)=0; jigsawMask(bool4)=0; jigsawMask(253-25:253+25,51:505-50)=1; jigsawMask(1:152,253-25:253+25)=0; jigsawMask(505-151:505,253-25:253+25)=0;
2为每片拼图块设置ButtonDownFcn属性，将其改造成按钮
完整代码：

运行m文件后选择一张接近方形的图片即可开始游戏
