[Closed] How to pick a group object?

you have to provide two methods – getRootGroupHead and getGeometryGroupMembers
to get this work:

(
	if (node = pickObject()) != undefined do
	(
		if (head = getRootGroupHead node) != undefined do nodes = getGeometryGroupMembers head
		format "head:%
	nodes:%
" head nodes 
	)
)
/*
head:$Dummy:Group003 @ [60.000000,20.000000,12.500000]
	nodes:#($Box:Box001 @ [40.000000,0.000000,0.000000], $Box:Box002 @ [80.000000,0.000000,0.000000], $Box:Box003 @ [40.000000,40.000000,0.000000], $Box:Box004 @ [80.000000,40.000000,0.000000])
*/

From schematic view

I run this

getGrandParentGroup $Box004
--$Box:Box005 @ [0.000000,0.000000,40.000000]

Why function ignore opened groups?

THESE ARE MY FUNCTIONS!!! ha-ha… you have to write your own. that what i was asking you

do you know how many geometry classes in standard max system are not really geometries?
11 (you check only 1 – TargetObject)

so you need another function to do – isRealGeometry

Now you could have fooled me
I already wrote my but … :). Anyway thanks. This was fun.

do they work correct now?

btw… all three my functions are only one line of code… so they are simple if you know what to do

here is improved test:

delete objects
(
	b0 = box pos:[40,0,0] wirecolor:orange
	b1 = box pos:[80,0,0] wirecolor:orange
	sn = snow()

	g0 = group #(b0,b1,sn)

	b2 = box pos:[40,40,0] wirecolor:green
	b3 = box pos:[80,40,0] wirecolor:green
	mr = mr_Proxy pos:[0,40,0]

	g1 = group #(b2,b3,mr)
	g2 = group #(g0,g1)

	in (box pos:[0,0,40] wirecolor:blue) (g2.parent = box pos:[0,0,80] wirecolor:red)
	for g in #(g0,g1,g2) do setGroupOpen g on
)

Can I use this to find out isRealGeomtry?(I add only two classes for check)

 for o in geometry where canConvertTo o editable_mesh and canConvertTo o editable_poly collect o

Can you tell me why:
> this works

b0 = box pos:[40,0,0] wirecolor:orange
b1 = box pos:[80,0,0] wirecolor:orange
in (g0 = group #(b0,b1)) (box pos:[0,0,40] wirecolor:blue) 

and this not

b0 = box pos:[40,0,0] wirecolor:orange
b1 = box pos:[80,0,0] wirecolor:orange
in (box pos:[0,0,40] wirecolor:blue) (g0 = group #(b0,b1))
