Spaceship/Spaceship.cpp@10:aca793aa7abc, 2020-04-22 (annotated)

Revision:
10:aca793aa7abc
Parent:

Reduced length of spaceship movement function using a switch statement. In the previous commit, I changed the draw line function in the LCD class; I changed its unassigned int variables to normal int variables as it was crashing the game.
