Features

• Dynamic Browser Creation: Create interactive browser screens of any size, anywhere in the game world.
• Real-time Web Rendering: Based on the Chromium engine, it can render modern web pages, including complex CSS and JavaScript.
• Fully Interactive:
  • Interact with web elements via mouse clicks.
  • Input text into forms and search boxes using commands.
  • Send specific key presses (like Enter, Shift, Backspace) for advanced control using commands.
• Developer Tools: Toggle Chromium Developer Tools in real-time to debug web layouts and performance directly in-game.
• Highly Configurable:
  • Enable remote debugging via config.yml to connect with Chrome DevTools.
  • Support for specifying a custom JCEF Bundle path.
  • Configure user-agent, user data path, and custom CEF arguments through config.yml.

Dependencies

• MapEngine (Required): This plugin depends on the MapEngine API for map rendering. Please ensure you have installed and enabled MapEngine on your server.

Installation

1. Download the latest MapBrowser-*-all.jar file from the Releases Page.
2. Ensure you have already installed the MapEngine plugin.
3. Place the downloaded MapBrowser-*-all.jar file into your server's plugins directory.
4. Start or restart your server.
5. On the first launch, jcef-maven will automatically download and install a custom version of CEF suitable for your server's operating system. Currently, only Windows amd64/i386 and Linux amd64/arm64 are supported. If our custom version is not available, MapBrowser will be disabled automatically. This process may take a few minutes and requires a good network connection. Please be patient and monitor the console logs.

Configuration

When the plugin loads for the first time, it will create a configuration file at plugins/MapBrowser/config.yml.
