Testing the game
Now we can run the game in the usual way. Notice the subHorizontalposition and subVerticalPosition variables in this abbreviated logcat output:
subHorizontalPosition: 30 subVerticalPosition: 13
Try running the game again and notice you will get different positions demonstrating that our Random based code is working, and we can confidently call newGame whenever we want to start a new game.
subHorizontalPosition: 14 subVerticalPosition: 7
Note
It is possible but very unlikely that you can call newGame and get a sub in the same position.
That's it, we now can spawn our sub' each new game.
