Project FOSSIL (v1.0): Use MV plugins in MZ! 300+ plugins Fossilized!

Restart · 2021-04-16T09:31:04+0900

Project FOSSIL V1.0 By: FOSSIL TEAM Introduction Project FOSSIL (Fixing Old Software / Script Interoperability Layer) is a single RPG Maker MZ plugin designed to expand the use and usefulness of RPG MAKER MV plugins, by allowing them to work in RPG MAKER MZ projects. FOSSIL doesn't port plugins. FOSSIL makes porting unnecessary! I got a copy of RPG Maker MZ a little while ago, and I think the editor is even better than RPG Maker MV. The only problem is that it's competing with RMMV's deep library of plugins. MV had such a huge number of great plugins (thanks to the tireless work of Yanfly, Moghunter, SRD, Galv, and too many other authors to list here) that it will be a long time before they all get rewritten to work with the new engine. I decided to try to figure out a way to speed things up. Instead of having to change every single MV plugin to work with MZ, I'm going to see if we can change MZ so it can work with the old plugins, and still keep all the engine upgrades. That way, we'll have the best of both worlds. What I came up with was FOSSIL. FOSSIL does basic interoperability things - it makes MZ able to understand commands from old MV plugins. For instance, when you make a window in MZ, the engine expects you to hand it a single 'rectangle' which tells it exactly where the window should go, and how big it should be. In MV, when you make a window, what you hand the engine can be very different - it might just be 'how many lines of text there are in this window', or it could be 'the x coordinate, y coordinate, width, and height'. Before any of those commands get to the core engine, FOSSIL converts them into the rectangle that MZ expects. That way, you don't have to actually change how the plugin tries to create a window - FOSSIL just translates it into terms MZ can understand, and then it's fixed everywhere. Plus, this way, we can make old MV plugins work in MZ while still respecting any licensing they have. Instead of having to track down people who might have left the community, and asking them if we can copy their plugin and make a changed version, we can just use FOSSIL and make MZ understand what the plugin is trying to do. I have tried my best to minimize any side-effects from FOSSIL's existence. In my test projects there weren't any noticeable changes, but it's entirely possible I accidentally broke something. If that's the case, please post about it in this thread. I'm super excited about the possibilities with FOSSIL, and I hope a lot of people join in (hence why I'm crediting FOSSIL TEAM). I don't want this to be 'my' plugin, I want the whole community to be able to use all the MV and MZ plugins with the newest engine, and I think everyone here who makes MV plugins knows enough to help improve it. How to Use FOSSIL is a single plugin that must go at the beginning of your plugin list. There are no settings to tweak. Since FOSSIL isn't a port, you still need to have the original, unaltered MV plugins, and put them into your game as usual. So far I have tested over three hundred working plugins (see list), and there's a good chance that even if they aren't listed, most simple plugins will just work 'out of the box' with no tweaks. How to Write a Fix for Fossil FOSSIL now automatically detects where plugins are in the list, and applies patches directly before or after the appropriate plugin. For example, WAY_Core needs us to back up the plugin manager commands before WAY_Core actually runs and changes them. Since we need to run the code before WAY_Core executes, this requires a PreFix. Here's the code in FOSSIL that makes that happen: Code: Fossil.loadPreFix('WAY_Core',function() { Fossil.backupPluginManagerCommands=PluginManager._commands; }) //^ see that closing bracket and parenthesis? //That's important not to forget. The 'WAY_Core' parameter in loadPreFix tells FOSSIL which plugin it should be looking at. The code for the fix itself is within the function: Code: function() { Fossil.backupPluginManagerCommands=PluginManager._commands; } Because this is loadPreFix, the code will be run just before WAY_Core is executed. If you need to be before multiple plugins, you can list all of them in an array ['pluginA','pluginB','pluginC'], and it will run immediately before the first one in plugin order (ignoring plugins that aren't in your project). If we use loadPostFix instead, the code would be run immediately after WAY_Core. (And listing multiple plugins in loadPostFix will result in applying the fix immediately after the last one in the list). Plugin Order There is only one order possible: 1) FOSSIL.js (First plugin) 2) All other plugins. Other than that, put the plugins ordered the same way you'd put them in MZ or MV. Put plugins that extend each other together like usual. I can't really give more specific instructions than that, it'll all be on a case-by-case basis as normal. Using Old Plugin Commands You have three ways of using plugin commands for MV projects A: use the built in plugin comman…

what plugin of the animation is it?

as if it has a sprite, you might be able to make it work within fossil
as I believe MZ has a "Sprite_AnimationMV" function.

if it has Sprite_Animation, just add MV behind it and it might work.
or link to the plugin to see if there is a MZ equalivant of it.

I did do the thing where I used an MZ animation slot and converted it into MV which required no extra plug-ins to do.

Hey ya'll, is anyone else ruunning into the following error now with Core Script 1.9?

Apparently fossil is trying to call iconWidth waaaaay early for no reason and it wasn't till now that it was a problem. lol

Alright! thanks to @CasperGaming , this is what to do.

Replace at line 2300:

Original Line 2300
Window_Base._iconWidth = ImageManager.iconWidth;
Window_Base._iconHeight = ImageManager.iconHeight;
Window_Base._faceWidth = ImageManager.faceWidth;
Window_Base._faceHeight = ImageManager.faceHeight;
Sprite_StateIcon._iconWidth = ImageManager.iconWidth;
Sprite_StateIcon._iconHeight = ImageManager.iconHeight;

with:

Updated lines 2300
Window_Base._iconWidth = ImageManager.standardIconWidth;
Window_Base._iconHeight = ImageManager.standardIconHeight;
Window_Base._faceWidth = ImageManager.standardFaceWidth;
Window_Base._faceHeight = ImageManager.standardFaceHeight;
Sprite_StateIcon._iconWidth = ImageManager.standardIconWidth;
Sprite_StateIcon._iconHeight = ImageManager.standardIconHeight;

While that will work for standard projects, it won't support the face/icon size settings introduced in 1.9.0 (which was what broke everything). Here's a version that will:

Victor Engine Battle Status Window does not work with Fossil in MZ. The game crashes and gives an error message as soon as a battle starts.

Sprite_StateIcon._iconHeight = ImageManager.getIconSize();

No. This will also cause an error. But tying to standard sizes is also a bad option.

Good morning, I spent 3 days trying to use MOG_LMBS in RMMZ and I was able to get it working using Fossil, I didn't modify or remove the existing Fossil code, I just added the patches and I hope I didn't break anything.

Added:
LMBS compatibility with MZ
DmgPopupEffects compatibility with MZ
LMBS compatibility with MZ's MOG_BattleCamera and MOG_BattlebackEX

Required:
MV's data/System.json and data/Animations.json files, without them, an error appears, I don't know why.

Not fixed:
The particle animations used by MZ are not displayed in the correct locations.

The Fossil file I used is:
GitHub - Aesica/fossil-MV-MZ: Project Fossil (Fixing Old Software / Script Interoperability Layer) is a series of RPG Maker MZ plugins designed to expand the use and usefulness of RPG MAKER MV plugins, by allowing them to work in RPG MAKER MZ project

10/03/2025
Changes:
1) Additional verification, to fix issue with PluginCommonBase.js and ExtraWindow.js:
arguments[0].constructor.name=='Rectangle'
Changed to:
arguments[0].constructor.name=='Rectangle' ||
(rect && typeof rect.x === "number" && typeof rect.y === "number" &&
typeof rect.width === "number" && typeof rect.height === "number")

2) New code for YEP_ItemCore to have MV style
3) Additional code for YEP_SkillCore compatibility settings with MOG_LMBS WindowSkillEquip
4) Adjusted help window in MOG_LMBS WindowSkillEquip
5) Additional code to adjust help window in YEP_StatAllocation

11/03/2025
Adjusted the position of MV animations to the base of MOG_LMBS sprites

13/03/2025
Fixed a bug that caused skill animations to display behind fighters in MOG_LMBS.

14/03/2025
The SkillCore LMBS compatibility code has been moved to the LMBS section. This caused an error in YEP_SkillCore with LMBS when it was disabled.

17/04/2025
1) YEP_ShopMenuCore: Fixed an issue where the window size and quantity position would not adjust correctly when resizing the screen.
2) FOSSIL: Fixed a bug with the MZ version (MOG_BattlerMotion and MOG_CollapseEffects).
3) LMBS: Fixed animation using the "LMBS Animation ID: X" note.
4) FOSSIL: Fixed a type error: animation.timings is not iterable.

I share the file:

Yep_CoreEngine is not working, it shows error
Aesica

#580 Mar 29, 2025, 07:56 PM Source

If memory serves, YEP_CoreEngine doesn't really offer a lot for MZ, since a lot of it is MV-specific bugfixes and optimizations. It might be worth just dumping it if you're able to.

Hi, thanks for your work on this,
using It on playtest It works great but it seems to break when using it on web (deployed a web version with the "FOSSILindex.html" renamed to "index.html" as I did for previous builds and upload on website)
It launches but seems to not load well some things (like some background images, or other files) and random crashes, here's a screen of the console:

Do u have an idea what could have caused this ? I've never had this issue before
Thanks again !

Does it happen every time you try to run it on the web? And which browser are you using? MZ's web deploy is pretty fickle even without any plugins.
