NPCs get stuck against platforms. #304

An NPC was following me and jumped up a platform and in doing so, became stuck 
against the side of it. See screenshot for visuals.

I have had this happen quite a lot to me, too. I made a patch a few months 
back, and that seemed to fix it at the time, but then I started noticing it 
again.

What happens is that the NPC keeps trying to move left, and they align in a 
perfect way that they keep getting "pushed up" instead of dropping down. The 
place they are stuck in that screenshot is actually where two walls join to 
make one large wall.

I was never able to figure out a good way to solve the issue without imposing 
much on performance. Luckily, this is only an issue for sidescroller users, and 
in reality, you probably won't even see it occur much. So at least its not a 
"breaking" issue.

Wouldn't the best way of fixing this be to just make any block below a platform 
block a wall (instead of another platform)?

There are no actual "platforms". The issue is when you have two walls on top of 
each other. Under just the right circumstances someone can "latch" on at this 
point between the two walls. With platforms instead of walls, this won't ever 
be a problem.

This should be fixed now. Could have sworn I already closed an issue related to 
this - must have been a different one.
