Jackkel's Persistent Switches

じ☆ve冰风

Persistent Data v5
    RPG Maker MV Plugin
    Jackkel Dragon
​

Introduction
    A quick and simple plugin to allow the use of persistent switches (which do not reset their values between saved games).

Features
    The ability to set switches/variables to be saved to a "persistent" save file, allowing them to persist across save games.
    An example of using this could be creating an ending list, or creating New Game+ elements that don't require a clear save file.

How to Use
    - Copy the plugin code into a .js file and add it to your project's "js/plugins/" folder. (Be sure to use the name given in the code's header!)
    - Load the plugin in RPG Maker MV's plugin manager for your project.
    - Modify the persistent switch/variable IDs as needed. More information can be found in the help text.

Notes
    - I created this plugin out of necessity for my own project, so it is very bare-bones and probably won't be updated often. Still, I hope it helps until someone comes up with a more expansive and user-friendly way to store persistent data.

Updates
    - v1: First release. October 26th, 2015.
    - v2: (Hopefully) fixed a problem with deleting MV's default global save data and overwriting default functions. Changed the file persistent data gets saved to from "global" to "filePersistent". (I'll try to change the name later... I couldn't get a custom filename function to work properly.) October 26th, 2015.
    - v2 hotfix: Added a function to rename the persistent data file to "persistent". October 26th, 2015.
    - v2 hotfix 2: Fixed a problem where loading a saved game would reset persistent switches in some cases. October 26th, 2015.
    - v3: Changed the loading code so that it wouldn't re-write the persistent file multiple times on loading a game. October 27th, 2015.
    - v4: Added a parameter to turn off automatic saving of persistent data. A general expression parser was provided by ArcherBanish to allow for an undefined number of persistent switches. ArcherBanish also provided two plugin commands that allow forcing a persistent save/load. October 28th, 2015.
    - v5: Added support for persistent variables. Note that this requires deleting your persistent save data from earlier versions of the plugin to work.

*
* This plugin provides persistent switches and variables that are saved to the
* "Persistent" save file, allowing you to set switches and variables that are
* not tied to a save game. Uses for this could include designing an ending list
* or creating New Game+ elements without requiring the use of a clear save
* file.
*
* The value for each switch/variable in configuration is the switch ID in the
* editor, without any leading zeroes ("10" instead of "0010").
*
* Example: Setting the persistent switches to "1-5,7" will set the switches with
* IDs 1, 2, 3, 4, 5, and 7 to be saved to the persistent data file.
*
* Plugin Command: Persistent Save
* Forces a save of the persistent data file.
*
* Plugin Command: Persistent Load
* Forces the game to load from the persistent data file.
*
* Thanks to "ArcherBanish" for writing the general expression parser
* to allow an undefined number of persistent switches and providing
* the plugin commands.
*
* This plugin is free to use, even in commercial projects. Credit "Jackkel
* Dragon" or "John Cooley".

(-1 = unused) * @Default -1 * * @param Persistent Switch #20 * @desc The ID of the persistent switch. (-1 = unused) * @Default -1 * * @Help * * This plugin provides up to 20 persistent switches that are saved to the * "Persistent" save file, allowing you to set switches that are not tied to a  * save game. Uses for this could include designing an ending list or  * creating New Game+ elements without requiring the use of a clear save  * file. * * The switch numbers in the plugin configuration are for internal use only: * you don't need to remember which switch is assigned to which persistent * slot. The value for each switch in configuration is the switch ID in the  * editor. * * Example: Setting the first persistent switch to be 15 will cause the switch * with ID 15 to be saved to the persistent data whenever it is changed. * * Note: If you don't need all the switches, you *should* be able to set the * plugin configuration for those switches to '-1'. (Needs more testing.) * * This plugin is free to use, even in commercial projects.

Potential Hotfix for problems in v5

Spoilervar _DataManager_createGameObjects = DataManager.createGameObjects;
DataManager.createGameObjects = function() {
_DataManager_createGameObjects();
PersistManager.load();
};

// Changed to:

var _DataManager_createGameObjects = DataManager.createGameObjects;
DataManager.createGameObjects = function() {
_DataManager_createGameObjects.call(this);
PersistManager.load();
};
