unity基础开发--鼠标移动物体并判断是否移动

using UnityEngine;using System.Collections;public class Comm_MoveGameObject : MonoBehaviour {    private GameObject mainCamera;    public static bool moveDown=false;    public static bool IsMoveGameObject=false;    private Vector3 currentPos;//初始位置// Use this for initializationvoid Start () {        mainCamera = GameObject.Find("Main Camera");        currentPos= this.gameObject.transform.position;}    IEnumerator OnMouseDown()    {            moveDown = true;            Vector3 screenSpace = Camera.main.WorldToScreenPoint(transform.position);//三维物体坐标转屏幕坐标            //将鼠标屏幕坐标转为三维坐标，再算出物体位置与鼠标之间的距离            Vector3 offset = transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenSpace.z));            //        print("down");            while (Input.GetMouseButton(0))            {                //屏蔽镜头旋转                mainCamera.GetComponent<MouseFollowRotation>().enabled = false;                //print("button0");                Vector3 curScreenSpace = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenSpace.z);                Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenSpace) + offset;                transform.position = new Vector3(curPosition.x, curPosition.y, curPosition.z);                yield return new WaitForFixedUpdate();//这个很重要，循环执行                ////对物体y进行限制                //if (transform.position.y <= limit_Y)                //{                //    transform.position = new Vector3(curPosition.x,limit_Y,transform.position.z);                //}            }                   }    void OnMouseUp()     {        moveDown = false;        mainCamera.GetComponent<MouseFollowRotation>().enabled = true;        //IsGameMove();    }// Update is called once per framevoid Update () {        IsGameMove();}    /// <summary>    /// 判断物体是否移动    /// </summary>    void IsGameMove()     {        if (currentPos != this.gameObject.transform.position)        {            //currentPos.transform.position            print("移动了");            IsMoveGameObject = true;        }        else        {            print("没有移动");            IsMoveGameObject =false;        }    }}

脚本放在需要移动的物体上，ok
