Confirmation box

This script is designed for RPG Maker VX.

Here's the system I use to confirm choices from a player. Put the script below in the Materials section, after all other scripts.

def pbShowChoices(text,choices,cancelType)
    messageWindow=Window_Message.new
    messageWindow.z=100000
    retval=-2
    $game_message=Game_Message.new if !$game_message
    if !$data_system
      $data_system=load_data("Data/System.rvdata") rescue RPG::System.new
    end
    $game_message.texts.push(text)
    if $game_message.texts.size <= 4 - choices.size
      $game_message.choice_start = 1
      $game_message.choice_max = choices.length
      for s in choices
        $game_message.texts.push(s)
      end
      $game_message.choice_cancel_type = cancelType
      $game_message.choice_proc = Proc.new { |n| retval=n }
    end
    while retval==-2
      Graphics.update
      Input.update
      messageWindow.update
    end
    messageWindow.dispose
    return retval
end


def pbConfirm(text)
  return pbShowChoices(text,["Yes","No"],2)==0
end
def pbConfirmCancel(text)
  return pbShowChoices(text,["Yes","No","Cancel"],3)
end

That script defines two methods:

<ul> <li> pbConfirm(X) - for simple Yes/No questions. <li> pbConfirmCancel(X) - for Yes/No questions, where the player can choose not to answer. Here are examples of their use:

if pbConfirm("Are you sure?")
   # Do it
end

code=pbConfirmCancel("Are you sure?")
if code==0
  # Do it and exit
elsif code==1
  # Don't do it and exit
else
  # Do nothing
end
