From group_nameX to intenger attribute

[bhbilbao]

Hi,
 need some help.
After using duplicate node. I marked "Create Output Groups" for the copies as: zone$CY
Now I have some groups inside primitives spreadsheet named group:zone1 |  group:zone2 | group:zone3..etc, with values 0 or 1.
I need to create a new intenger attribute named "zone" only with the number of the zone,

and then finally delete the groups. all this with attribute wrangle.

Thanks in advance.

string groups[] = detailintrinsic(0, "primitivegroups");

foreach(string s; groups){
    if (inprimgroup(0, s, @primnum)){
        i@zone = opdigits(s);
    }
}

 

There is no way to delete groups in VEX as far as I know. You will need to add a Group SOP and go to the Edit tab, then Delete and type zone*

Updated so it works with any number of groups, it would break after 10 groups before, new code should be fine

Thanks a lot Jero3D,

I saw that solution before in the forums but I dont understand why didnt work before.
I also solved in another ugly way, (except there is no value for zone0).
nodes:
name (group mask: zone*)
+
attribstringedit (From: zone . To: *empty*)

Bye.

using Name SOP for that purpose it's not an ugly way, that's one of it's uses

the ugly part is keeping the number as a string, why don' tyou just keep the name?, you can always extract int from is using opdigits() VEX function when needed

yes Tomas,

I finally stayed with the method explained by Jero3D. More clean.
Sorry about these questions but Im very newbie(1 week) with this software. I come here after more than 14 years with maya.
Thanks.
