chatting in chat with some contructors, and it's universally agreed that stairs are kinda hard to make in construct
1)stairs that you can either walk by, or walk up or down if you choose.
2)and stairs that can be walked up by one platformer, while walked through by another platformer
3)it's best if the solution doesn't require overriding the default platform behavior temporarily.
admittedly, I'd like a simple solution for my current project, but also, this could help anyone else who's gone through the various steps to try and implement stairs. (get it? steps?)
anyway, this is the simplest solution I could come up with without overriding default platform behavior. and it's not as simple as I'd like. I feel there's probably a simpler way.
