lazer

So in my game swap each tile has to have the axis point at the bottom so that when i swap them around they all align but on one tile that i want swappable its a lazer shooter type thing but the problem im having is the axis point of the object has to be on the very bottom and so when the lazer shoots out it starts at the bottom of the object, and i need to somehow keep the axis point the same but shoot the lazer out up higher on the object.

I had one idea of just making the lazer allways attached to the the object, but then it for some reason ubstructs the ability to swap other tiles that are under the lazer even thow the lazer is a quarter of the size of the tiles and it is above them.

Ah never mind probably Im wrong!

I’m confused. Could you prepare a sketch?
