QB64 is a modern extended BASIC programming language that retains QBasic/QuickBASIC 4.5 compatibility and compiles native binaries for Windows, Linux, and macOS.

The _AXIS function returns the relative position of a specified axis number on a controller device.

Syntax

move! = _AXIS(axis_number%)

Example(s)

Reading multiple controller device buttons, axis and wheels.


FOR i = 1 TO _DEVICES
  PRINT STR$(i) + ") " + _DEVICE$(i) + " Buttons:"; _LASTBUTTON(i); ",Axis:"; _LASTAXIS(i); ",Wheel:"; _LASTWHEEL(i)
NEXT

DO
  d& = _DEVICEINPUT
  IF d& THEN '             the device number cannot be zero!
    PRINT "Found"; d&;
    FOR b = 1 TO _LASTBUTTON(d&)
      PRINT _BUTTONCHANGE(b); _BUTTON(b);
    NEXT
    FOR a = 1 TO _LASTAXIS(d&)
      PRINT _AXIS(a);
    NEXT
    FOR w = 1 TO _LASTWHEEL(d&)
      PRINT _WHEEL(w);
    NEXT
    PRINT
  END IF
LOOP UNTIL INKEY$ = CHR$(27) 'escape key exit

END 

Note: When there is no device control to read, a FOR…NEXT n = 1 TO 0 loop will not run thus avoiding a control function read error.
