标题: C#写的脚本，作用是鼠标拖动物体，但是出现了错误
代码如下：
using System.Collections; public class clickmove : MonoBehaviour { // Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

}
IEnumerator OnMouseDown()
{

Vector3 ScreenSpace = Camera.main.WorldToScreenPoint(transform.position);

Vector3 offset = transform.position-Camera.main.ScreenToWorldPoint(Vector3(Input.mousePosition.x,Input.mousePosition.y,ScreenSpace.z));

Debug.Log("down");

if(Input.GetMouseButton(0))
{

Vector3 curScreenSpace = Vector3(Input.mousePosition.x,Input.mousePosition.y,ScreenSpace.z);

Vector3 CurPosition = Camera.main.ScreenToWorldPoint(curScreenSpace)+offset;

transform.position = CurPosition;

//yield return new WaitForFixedUpdate();
}

}
}
错误提示：
