I've noticed traps and some walking enemies also clip through half solid combos. I've seen it happen with all four directions. With enemies though it seems random, like they only do it sometimes. It might have to do with them approaching the combo from the non-solid half.
I've never had issues with enemies, but then again I haven't used half-borders extensively. I suppose it's worth experimenting with, though even if it happened regularly, a simple No Ground Enemies flag should take care of it.
For traps, however, it's only happened when they move down so far, but it's happened every single time. Maybe it would also happen if they moved up in a different scenario. But in any scenario, they seem to respect left/right borders.
Edit: maybe being within the two tile border has something to do with it?
Wait, what two tile border?
Enemies moving through half-solid combos is normal.
Normal as in intentional? Or normal as in a long-standing bug that's never been fixed?
Also, traps should, like any enemies, get blocked by no enemy / ground enemy flags. It works that way in my quests at least ;P
I'd imagine they should, but they don't.
Is there some rule you check for your quests to make them work like that?
Theres a "line of sight traps move across the entire screen" quest rule, but I don't think it has anything to do with this issue.
Nah, that just keeps them from bumping into an invisible trap-barrier across the centers of the screen and bouncing back.
I kind of wish, even with that enabled, that pairs of two traps would still hit each other and bounce back rather than passing through each other.
