: These are compressed ZIP archives containing JSON configuration files, JavaScript scripts (via the Bedrock Scripting API), textures, and animation files. They utilize Bedrock’s native Add-on system to replace or expand existing game data.
Once both folders are ready, you need to package them for Minecraft Bedrock. Select both the MyMod_RP and MyMod_BP folders. Compress them into a single .zip archive. Change the file extension from .zip to .mcaddon .
: These contain compiled Java bytecode. They actively modify the game's internal code at runtime using modding APIs like Forge, Fabric, or NeoForge. They can introduce entirely new game mechanics, complex logic, and deep engine overhauls.
Difficult; often requires manual rewriting of code.
Ensure the manifest links the Behavior Pack to the Resource Pack so they load together. Step 4: Recreate the Mechanics (JSON and JavaScript)
If items appear as purple and black checkerboard squares, Bedrock cannot find your textures. Navigate to Settings > Profile > Enable Content Log File to see the exact directory path errors.
| Feature | Java Edition (.jar) | Bedrock Edition (.mcaddon) | | :--- | :--- | :--- | | | Java | C++ (via JSON & JavaScript/GoDot) | | Rendering | OpenGL (Lightweight Java Game Library) | RenderDragon (Proprietary) | | Modding API | Forge, Fabric, Quilt (Full code injection) | Gametest Framework, Addons (Sandboxed) | | Capabilities | Modify game engine, render distances, JVM arguments | Add entities, blocks, items, simple scripts |
Avoid any website claiming "Instant JAR to MCADDON Converter." They are either malware, scams, or produce broken packs that crash your game.
If textures are invisible or items do not appear, turn on the Content Log History in Settings > Profile . Minecraft will tell you exactly which line of JSON code has a typo or formatting error.
Use Blockbench to import Java models ( .java format). Blockbench allows you to export these as Bedrock geometry.json files.
To rebuild the mod for Bedrock, you first need to extract the visual and audio assets hidden inside the .jar file.
Bedrock uses a different format for 3D models ( .geo.json ) and textures compared to Java. Convert Java Models to Bedrock JSON
A .jar contains compiled Java bytecode. Bedrock cannot execute Java. An .mcaddon is simply a renamed .zip containing two folders: a behavior pack (logic) and a resource pack (visuals). There is no automated converter for code logic.
