[Closed] How to select a hierarchy

I’ve been using this snip in one form or another for a while, someone else may have something clearer though.

fn addChildrenToArray theChildren currentObjsToExport =
(
	for c in theChildren do
	(
		append currentObjsToExport c
		addChildrenToArray c.children currentObjsToExport
	)
)

currentObjsToExport = #(o)
addChildrenToArray o.children currentObjsToExport

You could also make use of the pathName literals in mxs:

fn children obj:selection[1] = (execute ("$'" + (obj.name)+"'/*/.../*"))

select (children())
children() as array
theChildren = children obj:$yourOwnObj as array

-Johan

And another take on it:

 fn getTheChildren obj:selection[1] includeParent:false = (execute ("$'" + (obj.name)+"'/"+(if includeParent then "" else "*/")+".../*"))
  
  select (getTheChildren includeParent:true)
  select (getTheChildren())
  
  getTheChildren includeParent:true as array
  getTheChildren() as array
  

-Johan

or alternatively:

fn getChildren obj includeParent:false selectObjs:false =
(
children = for c in obj.children collect c
for c in children do join children (for c in c.children collect c)
if includeParent do append children obj
if selectObjs do select children
children
)

Gravey – note that your function only returns the children and grandchildren; Vsai and JHN’s methods should return the entire hierarchy down from the node specified (so great-grandchildren, great-great-grandchildren, etc. as well).

Guibou – if you need -only- the children: $.children already returns an array with exactly that.

now thats a help page thats making me cringe.

I have to admit I don’t use it a lot either, it’s like regex for max But there is some useful stuff you can do it, like writing a single line expression to select an entire hierarchy

Johan,
your code is awsome and get all the hierarquy down, but deselect the current first object…

ObjectSet Values

[left]select <PathName>
[/left]
[left]Deselects any current selection first, then selects the node(s) you specified.
[/left]

so,
using selectMore instead select will keep the main selection :

[b][b]selectMore[/b][/b]  <PathName>
  [left]Adds the  specified node(s) to the current selection.
[/left]

  fn getTheChildren obj:selection[1] includeParent:false = (execute ("$'" + (obj.name)+"'/"+(if includeParent then "" else "*/")+".../*"))
       
       selectMore (getTheChildren includeParent:true)
       selectMore (getTheChildren())
       
       getTheChildren includeParent:true as array
       getTheChildren() as array
       

what about the standard DOUBLECLICK operation ?? 
eg. double click root select entire hierarchy ? is there any way to play around that ?

unfortnatly at this point, 
i can only think about using [i]keyboard.controlPressed[/i]...

If all you’re looking to do is select them, not to use them in a script/array you can use the built in ‘Select Children’ hotkey… i think it defaults to Control+PageDown, if not, just search Customize UI for it.
