How to make a platfrom traversable by the bottom

Hi,

I want to know how to make a platform traversable by the bottom like mario for example.

 

Hi,

This should work,

thank but in unity 4 ?

 

Seems like an odd question. I mean... how are you making the platforms traversable on their tops?

If I was making a game where the player and / or enemies could walk around a platform I'd just track which way their feet are. If walking on the top of a platform their feet would be down so shooting a ray down would detect the top of the platform allowing them to walk across it. If they were on the bottom of a platform the character's feet would be up so shooting a ray up would detect the bottom of the platform allowing them to walk across it.

 

i just create a zone which enable or disable collider of the platform

 

What happens if you use that same approach for the bottom of the platform?
