Input problem

[silver wind]

Hi guys, How do I know the input number command has finished ?
I'm calling rmxp's input command from a script.
It works, but.. consider the following code:

# a method showing the input window

$game_system.show_input(x,id,8,2)

#use the data stored in $game_variables[id]

use_the_data

line 4 executes before the input window even shows up
I've tried:

loop do

      # Update game screen

      Graphics.update

      # Update input information

      Input.update

      # Abort loop if input finished. I made message_waiting an attr_accessor

      if ! $game_system.map_interpreter.message_waiting

        break

      end

    end

But the result is an endless loop, as RMXP always executes the whole code first, and then the message windows.
Is there no way around it?
If I won't do it via script, I'll be forced break my scene, go to scene_map and call a common event to do the input. Help?

Hmm. I think I got it.
Someone may find it useful. This scene will show the input number screen + text
and return the number. So you can have a scene asking for input, without using an event command and a game variable.

Edit: The older version was buggy. Use this instead.

new window_Input

class Window_Input < Window_Message

  

  def initialize(text, digits)

    super()

    @var_id = 1

    start_input(text, digits)

  end

  

  def start_input(text, digits)

    @old_data = $game_variables[@var_id]

    $game_variables[@var_id] = 0

    $game_temp.message_text = text

    $game_temp.num_input_variable_id = @var_id

    $game_temp.num_input_digits_max = digits

    $game_temp.num_input_start = 1  # from_line

  end

  

  def finished?

    return @input_number_window.nil?

  end

  

  def get

    loop do

      # Update game screen

      Graphics.update

      # Update input information

      Input.update

      # Frame update

      update

      # Abort loop if screen is changed

      if @input_number_window.nil?

        break

      end

    end

    number = $game_variables[@var_id]

    $game_variables[@var_id] = @old_data

    return number

  end

  

end

To use, add a window_input to your scene:

@window = Window_Input.new(text, digits)
@your_number = @window.get
@window.dispose
