i'm entertaining the idea for a bridge that must do these things:
* not only player can use but any characters.
* characters can go under it, over it, and stand still on top of it (so it can't be just auto move over it to the next area).
though i'm not really sure where to begin with this. if i think about how passability is handled, that leads me to making seperate tables for anything on a bridge and flipping the character into "bridge mode" when walking onto it. but i may be overcomplicating things, i'm really looking for some insight from someone with experience in bridge stuff.
