How do I Handle floor buttons in 2d platformer

Hey all,

I'm trying to get some doors to open when the player is on top of a button object. I also want the button to respond to objects placed upon itself in the same way.

Is there a way to do this without using physics behaviour?

Your halp is much appreciated!

Not sure if it would work in your case but cant you check if an object is overlapping the button object and if so change the animation of the door object to open etc?
