1. See Wowpedia for more information on WoW Unit IDs. Will default to 'target' if nothing is specified as an argument.

Example

if enemy('target') then
  return cast(Frostbolt, 'target')
end
if enemy('target') then
  return cast(Frostbolt, 'target')
end

Note

This uses UnitCanAttack(unit1, unit2), returning boolean.
