I know this is likely very easy.
Getting confused by areas and their signals functionality. I've got a base building game with actors walking all over the place and from time to time new things are built in the base.
When something is built nobody can walk there anymore. However when it's built, it's possible there's already somebody there. I need to detect that so that I can move them out of the way.
Areas emit signals when objects enter or leave. But what do I do if the area needs to detect what's already inside when it's created?
