static function GetAxisRaw(axisName: string): float;
static float GetAxisRaw(string axisName);
static def GetAxisRaw(axisName as string) as float

Returns the value of the virtual axis identified by axisName with no smoothing filtering applied.

The value will be in the range -1...1 for keyboard and joystick input. Since input is not smoothed, keyboard input will always be either -1, 0 or 1. This is useful if you want to do all smoothing of keyboard input processing yourself.
