Corrected my functions so an asterisk can now get written to the LCD with the proper initialization. C2C Mossing helped me correct this.
Updated button library to work for port 2
Updated button.c to initialize interrupts for buttons. Defined numbers and variables in game.c, main.c, and game.h. Added interrupts to main.c. Beginning to make interrupts work for buttons. Referenced C2C Mossing's code for help.
Updated the moveplayer function. Referenced C2C Mossing's code to help me through this.
Added functions to main.c to update position of asterisk depending on which button is pressed. Changed movePlayer function in game.c to update positoin of asterisk. Still have to tie functions into interrupts. Had some trouble deciding whether to put functions in game.c or main.c. Referenced C2C Mossing's code to accomplish this step.
