Zelda Style Savegame Selection

[alexanderpas]

(for general community usage )

very simple explained, probaly harder to make

Change the default behaviour of the game startup so instead of the required choice between "New Game" and "Continue" you would select any ("Empty" or "Filled") Savestate, and if you selected an "Empty" savestate, it would start a new game, however, if you selected a "Filled" savestate, it would continue where you saved the game the last time (obviously )
Also, an option to copy(and overwrite) and delete(with confirmation) savestates also should be added.

Also, to allow other scripts to take advantage of this script a variable should be included where the number of the savestate is stored
This number shouldn't be saved into the savegame, but should be set whenever a savegame is loaded.

other things you might look into:
SDK-Compliant

questions? don't hesitate to PM!

 

[alexanderpas]

anyone?

 

[Kuri$u]

Hmmm, I took a crack at this.
I can manage the loading bit. but. I don't know how to set it as startup. I'm not that good

 

[Elijah von Bose]

I just made a basic version, and it seems to work. No use in making it SDK compliant, because I don't like the SDK. ^_^.

Replace your Scene_Load with that.
Main

#==============================================================================
# ** Main
#------------------------------------------------------------------------------
#  After defining each class, actual processing begins here.
#==============================================================================

begin
  # Prepare for transition
  Graphics.freeze
  # Make scene object (load screen)
  $scene = Scene_Load.new
  # Call main method as long as $scene is effective
  while $scene != nil
    $scene.main
  end
  # Fade out
  Graphics.transition(20)
rescue Errno::ENOENT
  # Supplement Errno::ENOENT exception
  # If unable to open file, display message and end
  filename = $!.message.sub("No such file or directory - ", "")
  print("Unable to find file #{filename}.")
end

That will not do exactly what you want, but instead just creates the Load Screen on start-up, then when you choose an empty slot, it creates a new game, and when you choose a filled slot, it goes to that game. It's still the generic load screen ^_^.

 

[alexanderpas]

thanks for this part :D this made me have some more idea's, I'll put them into a new request, consider this request done (unless someone is able to do the copy and delete options!!!)

oh, and thanks to your approach i found out how some things worked and managed to remove the choice window in Scene_Title

Spoiler: Code (add before main.)
