This needs to be a Vector2 and required.

The comment is contradictory, the value is not only used for Pointy-Top Hexagons, but an aid to calculating the long diagonals. Better comment: We assume a pointy-top orientation.

Please don't do this. Require the Vector2 and use it as per the original code. You cannot guarantee Phaser will exist in the global scope.
