Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition) + new Vector3(0, 0, 10);

代码解析：
1.屏幕坐标转化为三维坐标
Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition) + new Vector3(0, 0, 10);
2.物体跟随鼠标移动
transform.position = mousePos;
3.创建预制体
if (Input.GetMouseButton(0))
{
Instantiate(PrintPrefab, transform.position, transform.rotation);
}
把脚本给一个空物体就行。空物体的坐标为(0,0,0)，旋转坐标为(0,0,0)
