******Silent Hunter******
By Kai Zhuang
2018.10.2
The game idea is from one of my favorite game
Silent Hunter by Ubisoft.
(I was planning to make more ships and a mechenic
that the ship can attack player by deep water bomb
, but im running out of time...)
Use W,A,S,D to control the submarine
Press J to lanuch missiles

float subX; //Set variable for submarine's horizontal position
