AEE - Data Manager

[Crazyninjaguy 9]

Introduction

 

Just to be clear, this is a Scripter's Tool, and will do nothing by itself.

After attempting to add a game class into a savefile, and not being able to due to not being allowed to alias a module's methods (Unless i've overlooked something), I wrote this.

This allows scripters to add their own Game Classes into savefiles, and load them with the normal savefiles.

Simply alias the create_extra_objects, get_files_to_save and the extract_save_contents methods with your extra classes, and the script will do the rest.

 

Example

 

This is an example of how to use the AEE Data Manager system.

 

class AEEDataManager
alias aee_datamanager_musicplayer_createobjects create_extra_objects
def create_extra_objects
aee_datamanager_musicplayer_createobjects
$game_music = Game_Music.new
end
alias aee_datamanager_musicplayer_getfilestosave get_files_to_save
def get_files_to_save(contents)
aee_datamanager_musicplayer_getfilestosave(contents)
contents[:music] = $game_music
end
alias aee_datamanager_musicplayer_extractfiles extract_save_contents
def extract_save_contents(contents)
aee_datamanager_musicplayer_extractfiles(contents)
$game_music = contents[:music]
end
end

Thanks a lot CNG! Now I can finally play with those variable classes... hehehe...

To alias a module method:

module MyModule

 class << self
alias old_method_name my_method
 end

def self.my_method
 ## and put your stuff here and call the old method
end

end

[Victor Sant 273]

or just use

 

class << MyModule
 alias :old_method :method
 def method
#stuff
old_method
 end
end

 

that way you can use your module as a normal class (no need to add def self.method, just use def method)

I thought you'd probably be able to do it some way or another, silly me for not looking it up first :3

I guess my script is still useful as I can't see a way of aliasing code into the middle of the make_save_contents method.

 

Thanks for the heads up Kread-EX and Victor!
