String Error

[someperson]

Ok, a script I got here works fine when I test my game in test play. Now I exported a demo version encrypting the game data and if I run the game, I get an error about nil not being able to convert to a string and the error is in this script.

#==============================================================================
# ** Scene_Title
#------------------------------------------------------------------------------
#  This class performs title screen processing. Created by Khmp
#==============================================================================

class Scene_Title
  #--------------------------------------------------------------------------
  # * Constant Variables
  #--------------------------------------------------------------------------
  Swap_Frames = 2.5
  
  # Don't mess with the one below this line.
  Titles = Dir["Graphics/Titles/*.{png,bmp,jpg,jpeg}"]
  Titles.each_index { |i| Titles[i] = Titles[i].split('/').last }.sort!
  #--------------------------------------------------------------------------

  alias sope_animatedtitle_scene_title_update update
  #--------------------------------------------------------------------------
  # * Frame Update                                                    !ALIAS!
  #--------------------------------------------------------------------------
  def update
    # Declare the timer if it doesn't exist.
    @timer = Swap_Frames if @timer.nil?
    @title_index = 0 if @title_index.nil?
    # Reset the background and the timer when it reaches 0
    if @timer <= 0
      @title_index += 1
      @title_index = 0 if @title_index == Titles.size
      @timer = Swap_Frames
      @sprite.bitmap = RPG::Cache.title(Titles[@title_index])
    end
    @timer -= 1
    sope_animatedtitle_scene_title_update
  end
end

Please help, greatly apreciate.

Hmmm that is a toughy. Let me play around with it a little.

[edit]
Well I didn't think of this kind of problem when I created that code. But when you encrypt the game the actual tangible file path that it looks to "Graphics/Titles/" no longer exists. It's most definitely the use of Dir.([]/glob) that crapping out. And I'm not knowledgeable enough with Ruby or RGSSAD to figure out a fix for that particular problem. Maybe there's a different way to view the contents of the directory. But I don't know it offhand.

The easy solution would be hard coding it. And I think that would be a good idea at this point. Besides, at the time you go to encrypt the game there won't be any changes anyway. Oh and there was a bug if there were no Titles in the Array. So now it error checks for an empty Array and also checks to see if the bitmap exists before swapping:

#==============================================================================
# ** Scene_Title
#------------------------------------------------------------------------------
#  This class performs title screen processing. Created by khmp
#==============================================================================

class Scene_Title
  #--------------------------------------------------------------------------
  # * Constant Variables
  #--------------------------------------------------------------------------
  Swap_Frames = 50
  
  Titles = [
    'Title1.png',
    'Title2.png',
    'Title3.png',
    'Title4.png',
    'Title5.png',
  ]
  #--------------------------------------------------------------------------
  # * Alias Methods
  #--------------------------------------------------------------------------
  alias sope_animatedtitle_scene_title_update update
  #--------------------------------------------------------------------------
  # * Frame Update                                                    !ALIAS!
  #--------------------------------------------------------------------------
  def update
    unless Titles.empty?
      # Declare the timer if it doesn't exist.
      @timer = Swap_Frames if @timer.nil?
      @title_index = 0 if @title_index.nil?
      # Reset the background and the timer when it reaches 0
      if @timer <= 0
        @title_index += 1
        @title_index = 0 if @title_index == Titles.size
        @timer = Swap_Frames
        begin
          @sprite.bitmap = RPG::Cache.title(Titles[@title_index])
        rescue

        end
      end
      @timer -= 1
    end
    sope_animatedtitle_scene_title_update
  end
end

Sorry for that short sightedness someperson.

It only happens if I export the game with encrypted data. If I don't, it runs fine. Only reason I export with encrypted data is then no project files appear and my resources can't get directly stolen.

So when you encrypt, file directory goes bye-bye, like khmp said.

Ok so how do I hard code it? May sound like a nub question but I know nothing when it comes to ruby scripting. I can read it and try and figure out what is going on but not create code. Also, khmp, don't worry about it to much. We all make mistakes.

Oh just look at the new code I gave you above. You'll see that the Array has data like "Title1.png", "Title2.png" etc. Now though you actually have to fill in the Array yourself rather than have it be dynamic. If you need help with it let me know.

So just replace "title1, title2, etc" with the title file names in the correct sequence?
