方法1：Translate

this.transform.Translate( Vector3.normalize( 目標位置 - 自身位置 ) * ( Vecotr3.Distance( 自身位置, 目標位置 ) / ( 所用時間 * Time.deltime )));

方法2：Vector3.Lerp差值

	public Transform pointStart;
	public Transform pointEnd;
	public float time;
	
	private float distance;
	private float moveSpeed;
	private float startTime;
	private float friction;
	
	void Start()
	{
		distance = Vector3.Distance( pointStart.position, pointEnd.position );
		moveSpeed = distance / time;
		startTime = ( Time.time - startTime ) * moveSpeed / distance;
	}
	void Awake()
	{
		friction = ( Time.time - startTime ) * moveSpeed / distance;
		transform.position = Vector3.Lerp( pointStart.position, pointEnd.position, friction );
	}
