Supplied routines in HW_Input.i ------------------------------- Subroutine Returns GetKey d0=raw key code, unchecked! GetChar d0=valid ASCII code or 0. WaitForChar d0=valid ASCII code. Joysticks ~~~~~~~~~ Can substitute JOY0DAT for JOY1DAT if reading Port 0. Bit 1 of JOY1DAT is set if the joystick is being moved right. Bit 9 of JOY1DAT is set if the joystick is being moved left. Bit 0 EOR'd with Bit 1 of JOY1DAT will be TRUE if joystick is moved down. Bit 8 EOR'd with Bit 9 of JOY1DAT will be TRUE if joystick is moved up. Port 0: bit 6 of CIAAPRA is cleared when the fire button is pressed Port 1: bit 7 of CIAAPRA is cleared when the fire button is pressed Supplied routines in HW_Input.i ------------------------------- Subroutine Returns ReadJoy0 d0=movement code (see below) ReadJoy1 d0=movement code (see below) bit 0 set = right movement bit 1 set = left movement bit 2 set = down movemwnt bit 3 set = up movement The Mouse ~~~~~~~~~ Bit 6 of register CIAAPRA reflects the state of the left mouse button. label btst.b #6,$bfe001 button pressed? bne.s label no, keep waiting! The state of the right mouse button is reflected in bit 2 of the byte at address $dff016. label btst.b #2,$dff016 button pressed? bne.s label no, keep waiting!
