Unity 移除资产

Question

我试图在将资产添加到对象数组后卸载它们，但它返回一个错误，说我一次只能删除一个，但我不知道该怎么做

object[] tempItems = Resources.LoadAll("Inventory/Weapons");
foreach (object i in tempItems)
{
    GameObject it = (GameObject)i;
    Debug.Log(it);
    itemList.Add(it);
    Debug.Log(itemList.Count);
}


foreach (object i in tempItems)
{
    GameObject it = (GameObject)i;
    Resources.UnloadAsset(it);
}

UnloadAsset 只能用于单个资产，不能用于 GameObject 的/组件或 AssetBundles

我正在使用

    UnityEngine.Object[] tempItems = Resources.LoadAll("Inventory/Weapons");
    foreach (UnityEngine.Object i in tempItems)
    {
        GameObject it = (GameObject)i;
        Debug.Log(it);
        itemList.Add(it);
        Debug.Log(itemList.Count);
    }
    foreach (UnityEngine.Object i in tempItems)
    {
        Resources.UnloadAsset(i);
    }

但我仍然收到错误

UnloadAsset may only be used on individual assets and can not be used on GameObject's / Components or AssetBundles

这是错误所在的行

        Resources.UnloadAsset(i);

卸载Object 而不是GameObject。强制转换 GameObject it = (GameObject)i;Resources.UnloadAsset(it); 完全没有必要，而且很可能是问题所在。

Object[] tempItems = Resources.LoadAll("Inventory/Weapons",typeof(GameObject));
foreach (Object i in tempItems)
{
    GameObject it = (GameObject)i;
    Debug.Log(it);
    itemList.Add(it);
    Debug.Log(itemList.Count);
}

foreach (Object i in tempItems)
{
    Resources.UnloadAsset(i);
}

我还建议您使用带有大写“O”的 Object。不要认为它会有所作为，只是以防万一。
