《Pygame实现记忆拼图游戏13》中实现鼠标点击图案后会显示图案的功能，接下来实现的是比较两个图案是否相同的功能，如果相同，则会一直显示这两个图案，否则在显示了这两个不同的图案之后，会遮盖这两个图案，如图1所示。

图1 比较两个选中的图案

实现以上功能的步骤是：首先判断用户是第一次选中图案还是第二次选中图案，如果是第一次选中，则记录该图案；如果用户是第二次选中图案，接下来则获取这两次选择图案的形状和颜色，并进行比较（选中这两个图案，此时图案就会显示）；如果两次选择的形状和颜色不同，最后遮盖这两个图案，等待用户继续选择。

1 判断用户是第一次选中图案还是第二次选中图案

在main()函数中，接着《Pygame实现记忆拼图游戏13》中提到的代码，判断用户是第一次选中图案还是第二次选中图案，如图2所示。

图2 判断用户是第一次选中图案还是第二次选中图案的代码

其中，第40行代码中判断第一次选择的标志firstSelection是否是None，如果是则说明是第一次选择，此时通过第41行代码记录第一次选中图案的列数boxx和行数boxy。第一次选择的标志firstSelection在while True循环之外定义，初始值是None。

2 获取两次选择图案的形状和颜色

如果用户是第二次选择图案，则获取两次选择图案的形状和颜色，代码如图3所示。

图3 获取两次选择图案的形状和颜色的代码

其中，第42行代码中的else与图2中的if匹配，表示用户是第二次选择图案；第43-44行代码通过自定义函数getShapeAndColor()获取第一次选择图案的形状和颜色；第45-48行代码获取第二次选择图案的形状和颜色。

3 遮盖选中的图案

接下来比较两个图案的形状和颜色，如果不相同，则将这两个图案遮盖（因为选中后这两个图案就显示了），如果相同，则不进行任何处理（因为选中后这两个图案就显示了）。代码如图4所示。

题4 遮盖选中图案的代码

其中，第48行代码比较两个图案的形状和颜色；如果不相同，第50行代码首先监听1秒钟；第51-53行代码通过自定义函数coverBoxesAnimation()遮盖选中的两个颜色；第54-55行代码将这两个图案的状态恢复为“遮盖”；第56行代码将第一次选择的标志firstSelection恢复为None。
