简单的资源加载功能

ResourcesManager.cs

using UnityEngine;
//资源管理
public class ResourcesManager
{
	public static T Load<T>(string folder, string fileName) where T : UnityEngine.Object
	{
#if UNITY_EDITOR
		T obj = UnityEditor.AssetDatabase.LoadAssetAtPath<T>(string.Format("Assets/{0}/{1}", folder, fileName));
		if (null != obj)
		{
			return obj;
		}
#endif
		int sep = fileName.LastIndexOf(".");
		if (-1 != sep)
		{
			fileName = fileName.Substring(0, sep);
		}
		return Resources.Load<T>(string.Format("{0}/{1}", folder, fileName));
	}
	public static UnityEngine.Object Load(string folder, string fileName)
	{
#if UNITY_EDITOR
		UnityEngine.Object obj = UnityEditor.AssetDatabase.LoadMainAssetAtPath(string.Format("Assets/{0}/{1}", folder, fileName));
		if (null != obj)
		{
			return obj;
		}
#endif
		int sep = fileName.LastIndexOf(".");
		if (-1 != sep)
		{
			fileName = fileName.Substring(0, sep);
		}
		return Resources.Load(string.Format("{0}/{1}", folder, fileName));
	}
