Numeric representation of the location of an entity in the game space. There are multiple forms of coordinate systems to cater to a variety of methods to map position.

Coordinate systems can vary from the system (such as Cartesian versus Polar), the dimension (2D versus 3D), and even the scale (on a pixel level versus by tiles). Questions under the purview of this tag often deal with the storage and reference of coordinate data as well as the calculations and formulae used in handling coordinate-based geometry.
