public static function GetAxis(axisName: string): float;
public static float GetAxis(string axisName);
public static def GetAxis(axisName as string) as float

Description

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.

This is frame-rate independent; you do not need to be concerned about varying frame-rates when using this value.

	// A very simplistic car driving on the x-z plane.

var speed : float = 10.0; var rotationSpeed : float = 100.0;

function Update () { // Get the horizontal and vertical axis. // By default they are mapped to the arrow keys. // The value is in the range -1 to 1 var translation : float = Input.GetAxis ("Vertical") * speed; var rotation : float = Input.GetAxis ("Horizontal") * rotationSpeed; // Make it move 10 meters per second instead of 10 meters per frame... translation *= Time.deltaTime; rotation *= Time.deltaTime; // Move translation along the object's z-axis transform.Translate (0, 0, translation); // Rotate around our y-axis transform.Rotate (0, rotation, 0); }
