// BehaviourInterface
//
// Behaviours direct the motion of a class of
// game objects.
//
// Behaviours also contain code that customize
// individual game objects beyond what the
// core components allow for.
//
// For example, BehaviourMissile contains code
// to kill the missile when it touches a tile,
// since [weakness to touch] applies only to
// objects, and not tiles. (Were weakness to
// touch to apply to tiles as well, then
// the objects the player picks up would
// be destroyed upon falling on the ground.)
//
// There's still some stuff to be worked out,
// but all in all, it works out rather well.
