The core AI scripts that control what a creature does makes use of a large set of variables in the default var_creature.xls local variable table. The variables and their affects are:

AI_BALLISTA_SHOOTER_STATUS	int	0	When set to AI_BALLISTA_SHOOTER_STATUS_AVAILABLE, will try to move to nearby available ballistae and fire them. Set to AI_BALLISTA_SHOOTER_STATUS_INACTIVE to disable. This variable is modified by the ai_ballista_h script to keep track of ballista-related activities while active.
