In the previous article, I went over the basics of MV tools. In this article, I’ll be going over the process of creating your own MV Tools.




Why Create Your Own?


MV Tools add extra shortcuts to the editor, and will pass the current project's path to the application that the user launches. The application could be a GUI application, or it could be a console-based application that simply performs some data processing using the current project's information.

It's mostly for user convenience, but it also makes your tool feel more official since it actually appears in the editor! Anyways, let's go through the process to creating your own MV Tool.


MV Tool Anatomy


MV Tools are actually quite simple:

  • There’s an exe file
  • There’s an “identification” folder.

And that’s really all there is to it.





This is the executable that will be launched when you press the icon in the editor. It can’t be any name though; it must be one of the following:


  • WindowBuilder.exe
  • TilesetBuilder.exe
  • SceneBuilder.exe

This is hardcoded into the editor, so it only expects one of these filenames. You can see it in the RPGMV.exe




Anyways for testing purposes, simply create a blank text file and rename it “WindowBuilder.exe”.




This what the editor uses to get information about your MV Tool. In this folder, there’s a file called “app” (no extension) and a folder called “toolbar” which basically holds a 32×32 pixel icon that will be displayed in the editor. The “app” file is just a text file that has three lines of text:




Anyways so let’s set up a sample “app” file and add an icon to the toolbar folder. You can just use notepad to create the “app” file, but make sure you have file extensions enabled in your file explorer.

Now, when you go and add it to the editor, it’ll find your tool with the details you entered




And finally, once you confirm, it will appear in your editor, like the official MV tools!




The hime app itself does nothing because it’s just an empty file called “WindowBuilder.exe”, but you can actually add any executable app to RPG Maker MV as long as it has the identification folder, and the exe is a valid name


For example, I went and added notepad++ to it, which is my text editor of choice that I use for all my MV plugin development and other programming



When you click on the notepad++ icon, the editor will launch notepad++, and it will actually open something




This is the Game.rpgproject file which sits in the base directory of your project folder! So basically RPG Maker MV sends the path to your project file to the application, which you can use to automatically load some data in the project for example.


Some Thoughts

So now you’ve learned how to create your own MV Tools. What can you do with it? Anything really. It’s just a regular application, so you can do whatever you can think of.

Of course, your application ideally should be able to run externally, but integrating it with the editor means that users who may not be as tech-savvy will be able to run your tool on their current project without having to go and open it from outside of the editor, which might not seem like that big of a deal but could be useful.
