前のプレイスルーの状態を維持しながら、新しいゲームを開始するプラグイン – GALV_NewGamePlus.js

Galv's New Game Plus
----------------------------------------------------------------------------
This plugin creates a "New Game Plus" system, which allows the player to
replay the game using certain things from their previous playthrough.

----------------------------------------------------------------------------
HOW IS WORKS
----------------------------------------------------------------------------
During the game, when the player gets to a point where you'd like for them
to be able to use their save data for a New Game+ (usually done when the
player completes the game), use a SCRIPT event command with:

Galv.NEWGP.activate();

This activates the ability to New Game+ in the current playthrough. The
player will need to then save their game after this script call.

Ths next time the player is on the title screen if any saved games have been
activated with the script call above, the "New Game+" option will appear.
This will take the player to the save file list where the player will be
able to choose from the saved games that have been activated, which will
have an icon on them as specified in the "Icon" plugin setting.

When a new game+ is started, the data specified in the plugin settings will
be transferred into the game from the chosen saved file.

----------------------------------------------------------------------------
PLUGIN SETTINGS
----------------------------------------------------------------------------
Variables
---------
The variable list setting along with the Variable Type setting control which
variables are transferred from the save file to the new game+.

Example Variable List:
34,56,90 a list of 3 variables
1-20,60-80 a list of variables between ranges 1-20 and 60-80
1-20,60-80,56,90 a list of variables between ranges plus 2 variables

Example Variable Type:
0 Only variables in the variable list are transferred over
1 All variables transferred over excluding those in the variable list

Switches
--------
All switches start as OFF by default in Rpg Maker when you start a new game.
Switches work in the same way as above using the Switch List and the
Switch Type plugin settings to control which switches are transferred over.

Actors
------
The actors setting again works as above to keep actor save file actor data.
However, actors do not have the "type" setting - the list contains ids of
all actors that you want to keep from the save file.

Remember, though, that when you have a "Change Party Member" event command
during your game, if you tick "Initialize" box when adding an actor to party,
then it will revert that character to starting level.

Items / Weapons / Armors
------------------------
These settings also work like Variables (above) using the item's ID in the
lists as desired.

----------------------------------------------------------------------------
SCRIPT CALLS
----------------------------------------------------------------------------

Galv.NEWGP.activate(); activates the game's New Game+ capability
(player needs to save after this)

----------------------------------------------------------------------------
CONDITIONAL BRANCH - SCRIPT:
----------------------------------------------------------------------------

Galv.NEWGP.isReplay() if player is playing a new game+ game
Galv.NEWGP.isReplay(x) if it's new new game+ playthrough x
Galv.NEWGP.isReplay(a,b) if it's a playthrough between a and b

Galv.NEWGP.isActive() if new game+ is active in current game

----------------------------------------------------------------------------
CONTROL VARIABLES - SCRIPT
----------------------------------------------------------------------------

$gameSystem.newGamePlus returns the amount of times New Game+ has
been used for the currently played file
