public class ObjectToPathAttribute : PropertyAttribute { public string _input; public ObjectToPathAttribute(string matchineName) { _input = matchineName; } }
using UnityEngine; using System.Collections; public class UITest: MonoBehaviour { [ObjectToPath("UITest)] public string _itemPerfabPath; // Use this for initialization void Start () { } // Update is called once per frame void Update () { } }
使用上面的代码可以通过拖拽一个prefab的方式把相应的路径直接存储到public string _itemPerfabPath里，省去键盘输入步骤。截图如下：
当prefab为空的时候的截图如下：
