Paint Order for instance

Last reply by danpost, over 5 years ago:

There is an undocumented behavior that actors are painted in the order they are added into the world. This would put the most recently actor on top of everything else. So, you can remove and add the one you want on top at any time.

Avoiding overlapping objects

This makes it appear your objects can span more than one grid square; yet, you only set exactly one square as not empty when you place an object. You need to set all squares an object covers as not empty for your code to work. Also, you need check all square an actor will cover to place that actor -- not just the one where it starts at.
