Player interacting with Box

Initially I thought this had something to do with physics, if your character is using the platformer behavior, how does one make it to where you can push a block or roll a boulder?

I thought assigning physics behavior would help, but couldn't seem to make it work.

Platformer simply does not work well with physics. The best way to do this is either:

-Overlay an invisible physics box which is over the player, however I doubt this will turn out well.

-Trash the platformer behavior, and make your own physics-based platformer using events. It's not that hard.
