BitFlag Enum

BitEnum.cs

[System.Flags]
public enum LaserDirection
{
    NONE        =       0,

    NORTH       =       1 << 0,
    NORTHEAST   =       1 << 1,
    EAST        =       1 << 2,
    SOUTHEAST   =       1 << 3,
    SOUTH       =       1 << 4,
    SOUTHWEST   =       1 << 5,
    WEST        =       1 << 6,
    NORTHWEST   =       1 << 7,

    OMNI        =       ~(~0 << 8)
}

// [System.Flags] sets the enum as a bitflag type
// NONE = 0 gives the option to have no values set
// each additional value takes 1 << x as the bitshifted value
// the final value is an "ALL" value
