Before:
    positions = []
    
    if ship_name == :battleship
      
      positions = [ [ x_position, y_position ], [ x_position + 1 * horizontal, y_position + 1 * vertical ], 
        [ x_position + 2 * horizontal, y_position + 2 * vertical ], [ x_position + 3 * horizontal, y_position + 3 * vertical ] ]
      
    elsif ship_name == :carrier
      
      positions = [ [ x_position, y_position ], [ x_position + 1 * horizontal, y_position + 1 * vertical ], 
        [ x_position + 2 * horizontal, y_position + 2 * vertical ] ]
        
    else

    end
    
    ship_positions[player_name][ship_name] = positions

After:
# Esse método iterate simplifica e otimiza o código
