This is a little modification i made for my program, if you don't have a modification like that, your pictures will always be replaced. I didn't created all the script, i just modified a few parts.

The code isn't so good, any ideas for improvement?

If you never used this system:
- You will need a DLL(i will post in an attachment);
- You will need the script(the script in this topic);
- You will need to put on every scene in def update: Screen::shot if Input.trigger?(Input::F5)
I am using F5 for example, you can change for any key if you know how

by default the picture will have the name Screenshot_# and will be placed in the folder Screenshots, it will be 640x480 in a .png(change if you have another resolution)!

An idea for advanced users is put this on main script: Dir.mkdir('Screenshots') unless File.exist?('Screenshots')
If the player delete the folder the program will replace(If you don't want to make the folder this is good too)

The script is here...

Code:

#==============================================================================
# Module Screen
#------------------------------------------------------------------------------
# Let you have the function Screenshot when press a button(F5)
# You must have screenshot.dll
#################################################################
# Screenshot V2
# Screenshot Script v1 & screenshot.dll v1 created by: Andreas21

module Screen

  @screen = Win32API.new 'screenshot', 'Screenshot', %w(l l l l p l l), ''
  @readini = Win32API.new 'kernel32', 'GetPrivateProfileStringA', %w(p p p p l p), 'l'
  @findwindow = Win32API.new 'user32', 'FindWindowA', %w(p p), 'l'
  module_function

  def shot(file = 'Screenshot_', typ = 2)
    typname = typ == 0 ? '.bmp' : typ == 1 ? '.jpg' : '.png'
    @file_index = 0
    @file_index += 1 while FileTest.exist?('Screenshots/' + file + @file_index.to_s + typname)
    file_name = 'Screenshots/' + file + @file_index.to_s + typname
    @screen.call(0,0,640,480,file_name,handel,typ)
  end

  def handel
    game_name = "\" * 256
    @readini.call('Game','Title','',game_name,255,'.\\Game.ini')
    game_name.delete!("\")
    return @findwindow.call('RGSS Player',game_name)
  end
end

Reply if you have any doubt!
