Question: Does RPG Maker use JavaScript?

Answer

Yes, RPG Maker MV and its successor, RPG Maker MZ, utilize JavaScript for game development. They moved away from the Ruby-based scripting system used in RPG Maker XP, VX, and VX Ace.

In these newer versions, you can write custom plugins or modify existing ones using JavaScript. This gives developers much more flexibility and access to a wider range of web technologies that can be integrated into their games.

Here's an example of how you might create a simple JavaScript plugin for RPG Maker MV or MZ:

/*:
 * @plugindesc My first plugin for RPG Maker MV/MZ
 * @author Your Name
 *
 * @help This is a simple plugin that does nothing particularly useful.
 */

(function() {
    // Your code goes here

    var _Game_Interpreter_pluginCommand = Game_Interpreter.prototype.pluginCommand;
    Game_Interpreter.prototype.pluginCommand = function(command, args) {
        _Game_Interpreter_pluginCommand.call(this, command, args);
        if (command === 'MyPluginCommand') {
            console.log('Plugin Command Called');
        }
    };
})();

This rudimentary plugin extends the Game_Interpreter object to add a new plugin command. When "MyPluginCommand" is called within the RPG Maker MV/MZ event editor, it outputs a message to the console.

Using JavaScript opens up extensive possibilities for customization, from implementing new game mechanics to modifying UI elements. The robust community around RPG Maker also means there are many pre-written scripts available for use and learning.
