	public float speed = 8.0F;
	void Start() {
		float parameter = Mathf.InverseLerp(walkSpeed, runSpeed, speed);
	}
}

var walkSpeed = 5.0;
var runSpeed = 10.0;
var speed = 8.0;

function Start() {
	// parameter is now 3 / 5
	//现在参数是3/5
	var parameter : float = Mathf.InverseLerp(walkSpeed, runSpeed, speed);
}
