Screenshots




How to Use

-Download the JavaHut_SaveEx.js file and place it in your project's js/plugins folder. Once installed, Add it to the Plugin Manager, and click the Help... button for more info. If you are unsure about a plugin Parameter, double-click the value and read the description.


-For the demo, download the demo file and extract it to your RMMV Games folder, and open the Game.rpgproject file in RMMV.



Author's Notes

-If any of the plugin parameters are changed, please delete any save files that exist before running the game to prevent errors. To delete save files in a browser game, while the game is running, press F8 to open the console, click on "Resources" at the top, then click on the down arrow for "Local Storage" on the left side, select the file:// storage and delete all the save data.



FAQ

Q. Why does the autosave plugin command not work?


A. Make sure the Enable Autosave plugin Parameter is set to true.


Q. Why is the screenshot image of the autosave all black with no picture?


A. If you are fading the screen or doing other types of visual changes when running the autosave plugin command, the screenshot will capture the overall image at that specific time. Be sure to set a wait command if needed before running the autosave command.



Changelog

-Version 1.03: Added Warning Select Width parameter for custom prompt selector width.


  Fixed not being able to override Scene_Prompt and Window_Prompt from other scripts.


-Version 1.02: Added Warning Prompt Width parameter for custom prompt width.


-Version 1.01: Fixed a bug that caused the load warning to display when loading from the main menu.
  Fixed a bug that allowed autosave to trigger when loading the autosave file from the main menu.


-Version 1.00: Plugin completed.



Known Issues

-Autosave : Autosave will fail if the map contains an event that has a movement route set to move itself. This is because it contains a reference to itself, which breaks the JsonEx.stringify call in the DataManager.saveGameWithoutRescue method.


FIX: Use the autonomous movement, or another event's movement route to move the event as needed.
