Mhh... I'm still not following you (what do you mean by bridge?).
Perhaps a little example can make thing easier.
Black is solid, green is player, red is enemy.
Player should be able to stand on solid and be stopped by it (so he is forced to jump over it/climb it/go around it ). Enemy should be able to pass through solid as if it was just a background. If both (enemy and player) touch the solid at the same time, player should be stopped and enemy should be able to cross it.
Well thats several new rules rules now isn't it?
You won't be able to use solid on both player, and enemy if they both use platform, but it's all doable with overlap at offset.
