有的時候譬圣，想把某些對象如預制體瓮恭、音頻、圖片賦值到場景厘熟，不想每個資源都寫一個變量屯蹦，用list又沒法將不同的類型的對象放在一個數組里，同時想使用這些資源跟使用Resources下的資源一樣绳姨。那么接來下這個工具颇玷，就滿足了這些需求。
第一步就缆，創(chuàng)建場景資源腳本對象文件如圖

第二步帖渠，將相應資源拖到面板即可，可拖單獨文件竭宰，也可拖文件夾

到此資源就創(chuàng)建好了
第三步空郊，創(chuàng)建場景資源管理

將之前創(chuàng)建的資源腳本對象賦值到此處
第四步，獲取資源
假設想獲取的是某個音頻則代碼如下
SceneResources.Instance.Load<AudioClip>("xxxx");
這邊有個注意點切揭，就是假設狞甚，音頻文件和其他文件（如圖片）命名一樣，獲取的時候就可以加上相應的后綴,就能獲取指定對象了廓旬。
SceneResources.Instance.Load<AudioClip>("xxxx.mp3");
在如果哼审，音頻文件，有兩個同名，但是涩盾，在不同的文件夾下十气，這時候要獲取指定的，就可以通過路徑去獲取了

資源其實可以直接賦值到場景中春霍，只是這樣要修改資源的時候砸西，都要打開場景，所以這里單獨創(chuàng)建了一個資源腳本對象去管理資源址儒。這樣后續(xù)的修改就方便多了芹枷，每個場景對應一個資源腳本對象。
接下來看看代碼是如何實現的莲趣。
