MCEF 1.16

by luisca343

MCEF is a Forge library that embeds a Chromium web browser inside Minecraft, so other mods can draw HTML interfaces in the game.

What it does

MCEF wraps the Java Chromium Embedded Framework, a Java build of CEF based on Chromium, and exposes it to mods that need a browser surface. It contains a downloader that fetches the java-cef CEF binaries the Chromium browser requires on first use. The mod was originally created by montoyo and is published as an open source library under the GNU Lesser General Public License v3.0 or later.

Mod developers can build GUIs with HTML and CSS and use modern front-end tooling for their layouts. The project's own examples include a GUI built with NextJS and TailwindCSS, and a full screen Pokédex. The Teras mod uses this library, and the author also runs a sidemod for a Pixelmon server built on it. Windows 10 and 11 are supported on x86-64 and arm64, plus GNU Linux with glibc 2.31 or greater on x86-64 and arm64.

The mod is client-side only, so servers do not need it and players install it alone. It is published for Forge only, for Minecraft 1.16.5. Some antivirus software blocks MCEF from initializing, and the author advises whitelisting the mod files. The author also states that the mod can work on Android.

Key features

  1. Embedded Chromium browser

    Mods can display a Chromium browser inside the game window through the library's Java bindings.

  2. Binary downloader

    A built-in downloader fetches the java-cef CEF binaries that the browser needs, so mod authors do not ship them.

  3. HTML-based GUIs

    Interfaces can be written with HTML, CSS and JavaScript, including full screen layouts and custom rendering.

  4. Current Chromium version

    The browser follows a recent Chromium release, as stated by the author for the included binaries.

Use cases

Web-styled interfaces

Mod developers can build menus and screens with web front-end frameworks instead of Minecraft's own widget code.

Full screen panels

Examples in the project include a full screen Pokédex, showing a large browser-driven panel inside the game.

Who it’s for: Mod developers who want to build browser-based screens for Forge 1.16.5. Players do not need to do anything beyond installing the library that a dependent mod requires.

Questions

Does MCEF have to be installed on a server?

No. It is installed on the player's side alone, so servers need nothing.

Which mod requires MCEF?

Teras requires it, and it is the one dependent mod named in the catalog data for this library.

Why might the browser fail to start?

Some antivirus software prevents MCEF from initializing. The author advises adding the mod files to the antivirus whitelist.
