所以这里的playerMaterial财产实际上并非......有用。

它基本上是一张3x5索引卡，上面写着一本书的名字，它不是真正的书。所以当你这样做时：

GameManager.Instance.playerMaterial = GameManager.Instance.otherMaterial[index];

您正在删除索引卡上的图书名称并写入新书的标题，然后想知道为什么书架的内容没有改变。它并没有改变，因为你从未真正对书架做任何事情。

您需要更改播放器Renderer组件的素材属性才能更改。

E.g。类似......

GameManager.Instance.player.getComponent<Renderer>().sharedMaterial = GameManager.Instance.otherMaterial[index];
