Normally, when you get/set the position of an object, you actually get/set the position of the object's *center of mass*. In many cases this is enough, but when the object's center of mass *isn't exactly its geometrical position*, and you want to locate it (or locate something in it) geometrically, just "getting its position" won't cut it.

The trick to solve this is to take the vector reported by [[Get Position]] and **offset it by half the total size of of the object**. With total size, I refer to the minimum and maximum vectors of the object, added together.

Almost similarly, to set the geometrical position of the object, you set the position of the object to where you want to place it offset by half the total size, **negated**. Or, equally, subtract the offset from the geometrical position.
