unity, iterate immediate children and iterate all children

遍历所有直接子节点(immediate children)：

foreach (Transform child in transform)
{
    // do whatever you want with child transform object here
}

注：transform.childCount返回的是直接子节点个数。

遍历所有子节点（包括根节点本身及所有子孙节点）：

Transform[] allChildren = GetComponentsInChildren<Transform>();
foreach (Transform child in allChildren) {
    // do whatever with child transform here
}
