By writing this game harvest points:

1. The canvas Ispointinpath method does not support the FillRect, Strokerect context.

2. When canvas has an internal margin (padding), the coordinates of the incoming Ispointinpath method need to be subtracted from the padding value.

3. The method Json.parse (object) via JSON can quickly clone object objects, but note that cloning is still a reference relationship when there are methods in object objects.
