ABS very small edit

[craybest]

Hi there, I'm tusing a abs in my game, everything works very good, except for item drops.
monster don't drop any items at all, which isn't too bad but I would prefer it to be possible. is there a simple way to do it?
the part of the code where it checks if the enemy is dead and gives you exp/gold is here. maybe it's where the item part should be?

def check_dead_event(event)
    if event.is_a?(Game_Event)
      if event.monster_enemy.hp<=0
        get_event_exp(event)
        event.dead=true
        event.action = ACTION_DEAD
        event.action_time=MAX_DEADTIME
        event.set_through(true)
        event.start
        event.action_frame=0
      end      
    else
      actor_num = event
      actor = $game_party.actors[actor_num]
      if actor.hp<=0
        player = $game_players[actor_num]
        player.dead=true
        player.action = ACTION_DEAD
        player.action_time = MAX_DEADTIME
        player.action_frame=0
      end
    end
  end
  #--------------------------------------------------------------------------    
  def get_event_exp(event)    
    if event.monster_enemy!=nil
      if $game_settings.share_exp
        #t=(event.monster_enemy.exp / $game_party.actors.size).truncate
        for i in 0...$game_party.actors.size
          actor = $game_party.actors[i]
          lastlevel = actor.level
          actor.exp += event.monster_enemy.exp
          if actor.level > lastlevel
            self.animation_id.push($game_settings.levelup_animation_id)
          end
        end
      else
        if @actor_id == nil
          return
        end
        actor = $game_party.actors[@actor_id]
        if actor==nil
          return
        end
        lastlevel = actor.level
        actor.exp+=event.monster_enemy.exp
        if actor.level > lastlevel
          self.animation_id.push($game_settings.levelup_animation_id)
        end
      end
      $game_party.gain_gold(event.monster_enemy.gold)
     end
    end

any help will be appreciated
