For custom items, blocks, or entities, manual extraction ensures everything functions correctly without missing texture bugs. Step 1: Extract the Assets A .jar file is actually a compressed archive. Right-click the .jar file. Open it with an archive utility like 7-Zip or WinRAR. Extract the assets and data folders to your desktop. Step 2: Restructure for Bedrock
Inside it, create two subfolders: MyMod_RP (Resource Pack) and MyMod_BP (Behavior Pack).
: These require manual porting. You would need to rewrite the Java logic into Bedrock's JSON-based behavior packs or JavaScript-based GameTest Framework. Recommended Conversion Workflow convert jar to mcaddon work
Go to File > Export > Export Bedrock Geometry and save the file with a .geo.json extension. Step 4: Map Behaviors and Logic
mods run on Java and interact with the game's bytecode, while Bedrock Edition For custom items, blocks, or entities, manual extraction
: The first step is to open the .jar file, which is essentially a .zip archive, and extract all its assets. This includes the block and item models, textures, sounds, language files, and the Java code that defines the mod's logic.
The general workflow for converting a .jar to a working .mcaddon looks like this: Open it with an archive utility like 7-Zip or WinRAR
Java Edition uses a blockstate model system. Bedrock uses a .
: This is the hardest part of the conversion. The Java code cannot be directly executed in Bedrock.
Create a new root folder named after your mod. Move both your [ModName]_RP folder and [ModName]_BP folder inside it.
