CoordGrid

Checks whether this coord grid is within distance of the other coord grid. If the coord grids are on different levels, this function will always return false.

Checks if this coord grid is uninitialized. Uninitialized coord grids are determined by checking if all 32 bits of the packed property are enabled (including sign bit, which would be the opposite). As the main constructor of this class only takes in the components that build a coord grid, it is impossible to make an instance of this that matches the invalid value, unless directly using the single-argument constructor.
