getting the children of the first level in hierarchy
if i have this hierarchy:
root
object a
subobject a-1
subgroup a-2
subobject a-2-1
subobject a-2-2
subobject a-3
object b
subobject b-1
subobject b-2
object c
subobject c-1
subobject c-2
how to get the first level children with the parent being, for example, object a? if i use Array(objecta.GetComponentsInChildre(Transform)) then i get not only first level which is subobject a-1,subgroup a-2 and subobject a-3 but also children of the subgroup a-2
is there a way to get the first level children of given parent? thanks, any help appreciated!
Something like this:
Array array = new Array();
for (var child : Transform in objecta.transform) { array.Add(child); }
public static Transform[] GetTopLevelChildren(Transform Parent)
{
Transform[] Children = new Transform[Parent.childCount];
for (int ID = 0; ID < Parent.childCount; ID++)
{
Children[ID] = Parent.GetChild(ID);
}
return Children;
}
this is vine, I'll be adding this to my utils class.
I was thinking of doing similar way like get all childrens and check if the parent transform was the given one, it it was then it was the first levle child , similar to yours. I asume childcount will only count first level children tho, otherwise won´t work.
first level children:
var g = Selection.activeGameObject;
for (var child : Transform in g.transform)
all children:
var g = Selection.activeGameObject;
var allChildren = g.GetComponentsInChildren(Transform);
for (var child : Transform in allChildren) {}
The transforms are returned in order of the top level downwards if you get all objects in the parent, so if you know the number of children that should be in the first level. i.e. 16, you can just cycle through objects 1-17 of the array... object 0 with be the parent.
so using that method, it's possible to cound the first level childs using the first option, and then read from all transforms using that number + 1 to skip the parent.
