1:07:43ezysigh About the one entity per grid spot checking, how will you handle leaving a spot just before a monster lands there? Right now it's binary. Do you plan to add a fuzziness as you step off a square onto another one and a monster lands on your spot?

1:09:53guitarm87 Someday I will have to ask you about how to think when representing data in a program. I understand structs, enums, arrays and such. But what regulates when to use which?

1:14:06longboolean So the idea is to have the entity system both be able to support groups of entities that change from one into another (like a monster that mimics other objects), and entities that when separated from the group can take action on their own (like a necromancer resurrecting a ripped off arm)?
