Question

我正在尝试在Unity v5.0中使用Unity v4中创建的资源。在导入之后我修复了各种“过时”的错误，但我似乎无法绕过它。

我得到的错误是：

无法从'ViNode []'转换为'UnityEngine.Object'

此错误出现在以下行：

Undo.RecordObject(childNodes, "ReIndexChildren");"

我是否需要将childNodes转换为GameObject？或者我可以在这里使用Undo.RecordObject()的替代方案吗？

以下是资产的代码：

您不能将数组直接传递给Undo.RecordObject()（尽管您可以编写一个扩展方法来处理它，为方便起见）。这里最简单的方法是循环遍历childNodes并将ViNode的每个实例传递到Undo.RecordObject()：

if( GUILayout.Button( "ReIndexChildren" ) ){
    ViNode[] childNodes = node.GetComponentsInChildren<ViNode>();

    foreach (ViNode childNode in childNodes){
        Undo.RecordObject(childNode, "ReIndexChildren");
    }

    node.ReIndexChildren ();
}
