How do I jump on a object with physics enabled

Hi guys,

I am playing around with a new concept for a game and was wondering how i could jump on an item which has physics enabled? Currently when I do it, the object (I want to jump on) just shifts to move out of the way.

I have tried using the overlay collision detector and while this does make the object immovable, I would like it so that the character can jump on top & push the object Which is not possible with these settings

Any help would be greatly helpful!

Thanks,

Andrew
