The _LASTAXIS function returns the number of axis a specified number INPUT device on your computer has.

Syntax

axisCount% = _LASTAXIS(deviceNumber)

Description

  • Returns the number of axis that can be read on a specified device number within the number of _DEVICES found.
  • A valid number can be sent to the _AXIS function to find any relative axis movements.
  • The devices are listed in a numerical order determined by the OS and can be read by the _DEVICE$ function.
  • The _DEVICES function must be read before using _LASTAXIS or an ERROR Codes will occur.
  • Devices include keyboard(1), mouse(2), joysticks, game pads and multiple stick game controllers.

Example(s)

Checking for the system's input devices and number of axis.

devices = _DEVICES  'MUST be read in order for other 2 device functions to work!
PRINT "Number of input devices found ="; devices
FOR i = 1 TO devices
  PRINT _DEVICE$(i)
  IF INSTR(_DEVICE$(i), "[AXIS]") THEN PRINT "Axis:"; _LASTAXIS(i)
NEXT 


Number of input devices found = 2
