Parametersmobile @actor [, mixed @target]

    Returns 1 if the @actor can see the @target. The target entity may be an
object or character pointer or keyword. This differs from %canTarget()
such that this will return 0 for hidden mobiles while %canTarget() will
return 1 if the @actor can sense life. If the target is not defined then
it defaults to the current room.
