Reading controllers on the GameTank requires to add #include “input.h” as an include file. The API is pretty straighforward:
update_inputs();
if (player1_buttons & INPUT_MASK_LEFT) {
...
} else if (player1_buttons & INPUT_MASK_RIGHT) {
...
}
if (player1_buttons & INPUT_MASK_UP) {
...
} else if (player1_buttons & INPUT_MASK_DOWN) {
...
}
// players_old_buttons is used to make sure users press and release the button
if (player1_buttons & ~player1_old_buttons & INPUT_MASK_A) {
...
}
// players_new_buttons is also provided for convenience
if (player1_new_buttons & INPUT_MASK_B) {
...
}
