For touch events, Android provides three actions:
ACTION_DOWN
,
ACTION_UP
, and
ACTION_MOVE
,
when the user is pressing, releasing, and dragging fingers in the device screen, respectively.
When a finger press or release occurs, Doom sends a right control (
KEY_RCTL
) to the native
layer, which will result in the weapon being fired.
