Add external rollout as subrollout to Custom Attribute CA

Submitted by AshuraDX on Thu, 2017-11-02 12:13

Hey everybody!
I am working on a script based level design suite for an old idtech3 based game.
I have a large amount of repetitive GUI Elements that are common to many entities and I thought it'd be far more elegant if I could reference an external rollout in these classes instead of having to rewrite the same cod for each and every one of them.

But since I'm fairly new to Maxscript and I could not find a lot of information about this on the docs, My question is: how would I do that?

The Following Code snippet is one my Entity Class Definitions.
I would like to "outsource" then Spawnflag related Rollout Control elements along with the related functions to a "global rollout" that I can reference as a sub rollout.

--rootScene.MP_SpawnflagSets is a 2-Dimensional array that holds the label information for entity Spawnflags sorted into unique Sets.

Could anyone here give me an example of how to implement something like this?
