collision event.x event.y always 0

Hi

I simply want to know the collision point of two objects. I do it like this:

    ufocoll.collision = onLocalCollision2     ufocoll:addEventListener("collision", ufocoll)     function onLocalCollision2(self, event)         if ( event.phase == "began" ) then          print (event.y) end     end

The collision is detected but event.y is always zero. The gotchas don’t aply here.

Thanks for your help!

I found the cause: If the objects are sensors event.x / event.y always are 0. It would be nice if this box 2d limitation could be solved.

Hi @solala125,

Did you set the physics engine to report the collision point in content coordinates?
