Unity2D使用Tiled2Unity读取TiledMap中的自定义属性

继承Editor Scripts下的ICustomTiledImporter，实现HandleCustomproperties接口

例：

[Tiled2Unity.CustomTiledImporter]class CustomImporterAddComponent : Tiled2Unity.ICustomTiledImporter{    public void HandleCustomProperties(UnityEngine.GameObject gameObject,        IDictionary<string, string> props)    {        // Simply add a component to our GameObject        if (props.ContainsKey("AddComp"))        {            gameObject.AddComponent(props["AddComp"]);        }    }    public void CustomizePrefab(GameObject prefab)    {        // Do nothing    }}
