I encountered many problems

For example, if a random number starts to generate coordinates randomly, but there is always a loop, that is, the last blank lattice is not random.

I used the queue, joined all the empty grids, and then randomly selected several teams.

There is also the touch direction. I detected the distance between the start point and the end point X and Y. Then determine the upper, lower, and left.

The most troublesome thing is to move up and down, just a little different from the coordinate system.

I am using a matrix array, with the upper left corner being 0, 0. When the coordinates are calculated, the lower left corner is the initial state. Then add and subtract.

After the game is over, the screen sliding can continue, and I am sad for a long time, and finally close with a touch.
