         *  - Distance where attack using the actor's weapon is possible:
         *    longer for ranged weapons (obviously?) vs. melee weapons
         *  - Determined by weapon's reach parameter; hardcoded value
         *    for ranged weapon and for creatures
         *  - Once within this distance mFollowTarget is triggered
         *
         * rangeFollow:
         *
         *  - Applies to melee weapons or hand to hand only (or creatures without
         *    weapons)
         *  - Distance a little further away than the actor's weapon reach
         *    i.e. rangeFollow > rangeAttack for melee weapons
         *  - Hardcoded value (0 for ranged weapons)
         *  - Once the target gets beyond this distance mFollowTarget is cleared
         *    and a path to the target needs to be found
         *
         * mFollowTarget:
         *
         *  - Once triggered, the actor follows the target with LOS shortcut
         *    (the shortcut really only applies to cells where pathgrids are
         *    available, since the default path without pathgrids is direct to
         *    target even if LOS is not achieved)
