/* The beam is shot at the intercept point.
   A boolean back in the ShootingBehaviour object
   is set when the beam has reached the intercept.

   The explosion (ExplosionsClip) is also triggered from here.
   Another beam can be fired while the explosion is going off.

   We use a thread since the beam animation is meant to be separate
   from other activities, and is triggered from ShootingBehavior
   after the cone and beam are pointing in the right direction.
