/*
* Some notes on meanings of variables:
*
* rangeMelee:
* rangeAttack:
*
* - Distance where attack using the actor's weapon is possible
* - longer for ranged weapons (obviously?) vs. melee weapons
* - 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
* (TODO: check whether the follow logic still works for ranged
* weapons, since rangeCloseup is set to zero)
* - TODO: The variable name is confusing. It was ok when AiCombat only
* had melee weapons but now that ranged weapons are supported that is
* no longer the case. It should really be renamed to something
* like rangeStrike - alternatively, keep this name for melee
* weapons and use a different variable for tracking ranged weapon
* distance (rangeRanged maybe?)
*
* rangeCloseup:
* rangeFollow:
*
* - Applies to melee weapons or hand to hand only (or creatures without
* weapons)
* - Distance a little further away from the actor's weapon strike
* i.e. rangeCloseup > rangeMelee for melee weapons
* (the variable names make this simple concept counter-intuitive,
* something like rangeMelee > rangeStrike may be better)
* - 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
* - TODO: Possibly rename this variable to rangeMelee or even rangeFollow
*
* mFollowTarget:
*
