- attackCheckLOS [<boolean flag>]
- This option toggles the use of LOS (Line Of Sight) check code when attacking.
- If this option is enabled and you are a ranged attacker (i.e. attackDistance is set to a value greater than 2), this will check whether you have a clear line of sight to the target, if not, it will attempt to move to a space where you do while respecting runFromTarget_dist and followDistanceMax.
