Input.GetAxis

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);
