Here’s a step-by-step write-up on converting a to a Bedrock Edition .mcaddon (add-on). This is not a direct conversion — the two versions use completely different codebases (Java vs. C++) and APIs. Instead, you must recreate the mod’s functionality for Bedrock.
is a proxy server system. It translates Java server packets into Bedrock data in real-time. By installing Geyser alongside a plugin called Floodgate , Bedrock users on phones and consoles can join Java servers seamlessly, automatically processing server-side Java features without file conversion.
You may only port a mod if:
For most mods, expect to rebuild 80–100% of the work from scratch. Start with simple add‑on tutorials, then gradually re‑implement the Java mod’s features one by one. convert jar to mcaddon work
While you cannot auto-convert them, you can . This process is often called "recreating" or "porting" rather than "converting."
: Match the texture names to the model's JSON data.
No scripting needed. Total time: ~1 hour. Here’s a step-by-step write-up on converting a to
Java block and entity models use a different structural format than Bedrock.
Create BP/blocks/ruby_ore.json :
Note: Bedrock uses a different pattern orientation for tools. Instead, you must recreate the mod’s functionality for
"format_version": 2, "header": "name": "Converted Ores - Resources", "description": "Textures and names.", "uuid": "bbbbbbbb-cccc-dddd-eeee-ffffffffffff", "version": [1, 0, 0], "min_engine_version": [1, 20, 0] , "modules": [
You cannot do this with a simple converter app. You will need:
You cannot translate Java bytecode – you must re‑implement each function manually, referencing the original Java source if available (with permission).
: You can sometimes manually convert a .zip (or .jar opened as a zip) by renaming the file extension to .mcpack or .mcaddon after ensuring the internal folder structure matches Bedrock's requirements. 3. Recreating Logic (Behavior Packs)
There is no tool that magically turns Java bytecode into Bedrock add‑on behavior packs or resource packs. A .jar mod is compiled Java; an .mcaddon is a renamed .zip containing JSON files, textures, sounds, and optionally C++-compiled scripts. You must port the mod manually.
