Setup

Metadata Editor

This utility (accessible via Project and Utilities -> Metadata Editor) allows you to adjust the settings that are related to the executable. This includes settings like the window size, running scripts, etc.

NOTE

If your project doesn't have a package.json file, this utility will create it for you.

Setting	Description
HTML file location	This setting sets the main HTML file that the executable will load.
Game ID	The game's ID. Also determines the folder that will reside in AppData.
Version	The game's version. Usually used in scripts.

Setting	Description
Use NodeJS?	If this is turned off, NodesJS is disabled. This will turn off features that some plugins may rely on (saving to the hard drive as a file, for example).
Chromium Flags/JavaScript flags	These allow you to set Chromium and JavaScript flags for the game.
Game Name	The game's name.

Setting	Description
Window Title	The title of the window. Shown until the game loads up.
Window ID	When set, the window will remember its position.
Is Resizable?	If turned on, the user can resize the window.
Start as:	The window starts windows, in full screen or in kiosk mode (usually used for demonstration).
Start Location	Sets where the window will start.
Width/Height/Minimum Width/Minimum Height	Adjusts the window's size (both when it starts and it's minimum).

NOTE

Be warned! These settings are for advanced users and programmers. If you don't know what you are doing, it's best to leave them alone.

Setting	Description
Main script for NodeJS	Sets a script that NodeJS will run as its main program.
Background script for NodeJS	Sets a script that NodeJS will run in the background.

Asset Compressor

Accessible via Project and Utilities -> Asset Compressor, the utility will compress the game files. The images and audio are converted to WebP and Opus, respectively.

NOTE

Due to limitations, this tool will create a copy of the project that has the converted files. You can use that copy to then export the game with encrypted files.

The tool is easy to use, select the source project and output. Then click Convert.

The tool has the following settings:

Setting	Description
Image Compression/Use Opus	These enable or disable the compression for images and audio (repectively).
Image format	Select either WebP(a flexible format, capable of compressing losslessly or lossy) or AVIF (brings better lossy compression, but requires a newer version of NW.js.
Lossy Compression	Turn this on to compress the images in a lossy manner.
Image Quality	When using lossy compression, you can adjust the quality of the lossy images.
Compression level	Adjusts the level of additional compression for the finished images.
Chroma Subsampling	Currently available for AVIF compression. This is a compression technique that removes extra color information (while preserving the image's luminance). Setting it to 4:4:4, will disable this compression.

Font Compressor

This tool compresses the fonts to woff2 (and decompresses them to their original font file). Compressing the font file improves load times and contributes to smaller size (especially if you use multiple).

NOTE

This tool is more beneficial to RPG Maker MZ users. RPG Maker MV does support woff2 files. However, some plugins need to be re-adapted so they can load the files (in addition to editing the CSS file that is on the fonts folder).
