Unity, iterate immediate children and iterate all children

Traverse all direct child nodes (immediate children):

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

Note:Transform.childcount returns the number of direct child nodes.

Traverse all child nodes (including the root node itself and all descendant nodes):

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