* rangeAttack:

* - 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)

* - Distance a little further away than the actor's weapon reach

* - 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
