overlap(displayObject) → {boolean}
Checks to see if the bounds of this Game Object overlaps with the bounds of the given Display Object,which can be a Sprite, Image, TileSprite or anything that extends those such as Button or provides a getBounds method and result. This check ignores the hitArea property if set and runs a getBounds comparison on both objects to determine the result. Therefore it's relatively expensive to use in large quantities, i.e. with lots of Sprites at a high frequency.I
