Theoretical Gameplay and Lua Script Ideas

I have decided to set up a page for me to post (& possibly muse over) potential Lua Script & Gameplay functions & ideas for Visionaire Studio.

Character

Collision detection

In a script that Divo wrote - that allows the player to drag & drop objects around a scene - I seem to recall that in this particular script that he also made it so that the object polygon moved with the object, which has me wondering if we could not create something based on this script by combining some kind of border or non-walkable object & polygon around the npc characters so that the npc's can freely move around the scene & to make the playable character walk around them or interact with them somehow if the 2 characters collide.
