fsm Generic_PatrolRespond : integer;


//------------------------------------------------------------------

// Generic_PatrolRespond:
//   Follows a path.  If anything comes near, it goes off and attacks it,
//   and then comes back to the path when there's nothing left to attack.
//   When a specific trigger is set, it goes to another point or path
//   and does the same thing.

//   I.e. this is the same as Generic_Patrol, except that it
//   goes to a second point or path upon firing of a trigger.
