Stuck with something in scene_battle 4

[gerrtunk]

I'm trying to make weapons that can attack all the enemies:

 # Set array of targeted battlers

       #All weapon?

       if @active_battler.is_a?(Game_Actor) and @active_battler.todos_w? #Return true if the actor have a special weapon

        for enemy in $game_troop.enemies

          if enemy.exist?

            @target_battlers.push(enemy)

          end

        end

      end 

 

          [b]@target_battlers = [target] [/b]

 

      # Apply normal attack results   

      for target in @target_battlers

        target.attack_effect(@active_battler, target, $x_contr)

      end

 

 

I don't understand how the bold line works, a direct asignement of an object to an array??? without an index?

Now it just don't work. It only attacks one time, and if i delete the bold line the bucle dont make anything at all.
