# Input.GetAxis 获取轴

static function GetAxis (axisName : string) : float

Description描述

Returns the value of the virtual axis identified by axisName.

The value will be in the range -1...1 for keyboard and joystick input. If the axis is setup to be delta mouse movement, the mouse delta is multiplied by the axis sensitivity and the range is not -1...1.
