{{DISPLAYTITLE:_AXIS}}
The [[_AXIS]] function returns the relative position of a specified axis number on a controller device.


{{PageSyntax}}
: {{Parameter|move!}} = [[_AXIS]]({{Parameter|axis_number%}})


* [[SINGLE]] values returned range between -1 and 1 as maximums and 0 indicating minimum or axis center.
* When the mouse is moved on the program screen, moves left or above center are negative while below or right are positive.
* The ''axis_number'' must be a number which does not exceed the number of axis found by the [[_LASTAXIS]] function.
* '''The number of [[_DEVICES]] must be read before using [[_DEVICE$]], [[_DEVICEINPUT]] or [[_LASTAXIS]].'''
