当鼠标拖动Unity3D时如何做连续的动作？

using UnityEngine;

public class DragObject : MonoBehaviour
{
    private Vector3 initialMousePosition;
    private bool isDragging = false;

    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            initialMousePosition = Input.mousePosition;
            isDragging = true;
        }

        if (isDragging)
        {
            Vector3 currentPosition = Input.mousePosition;
            Vector3 displacement = currentPosition - initialMousePosition;

            // 根据位移量实现相应的连续动作，例如修改物体的位置或旋转角度
            transform.position += displacement * Time.deltaTime;

            initialMousePosition = currentPosition;
        }

        if (Input.GetMouseButtonUp(0))
        {
            isDragging = false;
        }
    }
}
