    shapes and collision

    Hi everybody,
    I'm trying to make some rectangular shapes to drag in the space.
    The thing i want to achieve is like the "Drag me" Gideros default example, but i don't want the shapes to overlap (I want to make a puzzle-like game so the pieces don't have to intersect).
    I tried with box2d dynamic bodies but the gravity is driving me crazy (even if i set it to 0 the bodies will keep going after I release the finger while moving).
    Ideas/tips/suggestions?
    Thanks

      use this function to chk collition
      function Sprite:collidesWith(sprite2)
	local x,y,w,h = self:getBounds(stage)
	local x2,y2,w2,h2 = sprite2:getBounds(stage)
 
	return not ((y+h < y2) or (y > y2+h2) or (x > x2+w2) or (x+w < x2))
end
      basically you need one array of all the shapes and you need to iterate through each to chk any overlaps on mouse_move event

      or at the time of mouse_down you can calculate minimum and maximum x and y position and then move accordingly assuming you are trying to make game like unblock me.

      @Diego_85 for box2d you may set the linear dampening of the body so it will not have such inertia.

      b2.Body:setLinearDamping(linearDamping)
