搜索部分在层次结构中查找对象，如果有子对象，它也会对它们进行计数。
替换部件将预制件替换为所选对象。例如，如果我选择了 20 个立方体并单击"替换"按钮，它将用具有相同位置、旋转、缩放立方体的预制件替换选定的多维数据集。
但如果有的话，它并不能取代孩子。
搜索时我需要以某种方式将父项和子项添加到列表中，并保留每个父项及其子项的层次结构，然后在单击替换按钮替换它时，搜索结果对象而不是像现在这样的选择，包括子项。
例如，如果我的层次结构如下所示：
Cube1
Cube1
Cube1
Cube1
Cube1
Cube1
如果我正在搜索 Cube1，我应该找到 6 个立方体，其中两个是孩子。 例如，如果我将它们替换为 Sphere 预制件，则层次结构应如下所示：
Sphere
Sphere
Sphere
Sphere
Sphere
Sphere
我需要做的是将搜索部分与替换部分结合起来，并使替换部分也包括子项。
你可以尝试这样的事情：
void ChangeObjectRecursively(Transform t)
{
for (int i = 0; i < t.childCount; i++)
{
ChangeObjectRecursively(t.getChild(i));
}
ChangeObject(t.gameObject);
}
