Do functions for cutscenes

[GhaztlyGames]

I'm trying to figure out how to call functions from scenes that aren't global scenes/scripts for cutscenes. I was watching the cutscene video and there was a portion in which variables were being exported and base scene was being extended.
I'm unsure of how i'd implement that, or if that's still using globals. I'm uneasy to use too many globals because I'm unsure if its normal to have tons of globals.

If you're using Dialogue Manager version 4.x you can now use DialogueStateContext nodes to achieve something similar. Anywhere they exist in the current scene tree they can expose a given node to dialogue with a given alias.
