UnityC#学习之-- Resources 特殊文件夹

Resources支持的加载类型:

1.预设体对象——GameObject

2.音效文件——AudioClip

3.文本文件——TextAsset

4.图片文件——Texture

...................

Object obj = Resources.Load("Cube");
Instantiate(obj);
//----------------------------------
GameObject obj = Resources.Load("Prefab/Cube", typeof(GameObject)) as GameObject;
Instantiate(obj);

GameObject obj = Resources.Load("Cube");
Instantiate(obj);

新开辟一个线程, 帮助加载资源

    private Texture tex;

    void Start()
    {
        ResourceRequest rq = Resources.LoadAsync("Tex/TestJPG");
        //添加回调函数, 在回调函数里取得资源
        rq.completed += LoadOver;
    }

    private void LoadOver( AsyncOperation rq)
    {
        print("加载结束");
        //asset 是资源对象 加载完毕过后 就能够得到它
        tex = (rq as ResourceRequest).asset as Texture;
    }

    private void OnGUI()
    {
        if( tex != null)
            GUI.DrawTexture(new Rect(0, 0, 100, 100), tex);
    }
