* Use ConvertGridNoToCenterCellXY instead of CenterX & CenterY * Add direction utility function We have a lot of places in the code that calculate direction based on center cell coordinates, but lack a utility function for it similar to other direction methods. * Use utility function for calculating direction * Use ConvertGridNoToCenterCellXY * Use utility function for direction * Use ConvertGridNoToCenterCellXY instead of CenterX & CenterY * Use ConvertGridNoToCenterCellXY instead of CenterX & CenterY * Remove CenterX & CenterY functions Use ConvertGridNoToCenterCellXY instead * Remove CenterX & CenterY calls from UB configuration * Address review feedback * Remove duplicate function ConvertGridNoToCenterCellXY and ConvertMapPosToWorldTileCenter do the exact same thing * Use PythSpacesAway instead of GetRangeFromGridNoDiff Both functions calculate the same thing * Remove GetRangeFromGridNoDiff * Remove calls to abs() The values end up being squared anyways making these unnecessary
