Navigate to and activate your converted pack. (The game will automatically pair and enable the Resource Pack).
Minecraft Java Edition uses pack.mcmeta for resource validation, while Bedrock Edition relies heavily on a manifest.json framework.
To bring a Java mod over to Bedrock, you must manually recreate the assets and rewrite the game logic. This guide outlines the proper process for manually converting and structuring your project into a working .mcaddon . 🛠️ Step 1: Extract the Java Assets how to convert jar to mcaddon patched
| Java Mod ( .jar ) | Bedrock Add-on ( .mcaddon ) | |-------------------|------------------------------| | Java programming language | JSON + JavaScript (Behavior Pack) / JSON (Resource Pack) | | Runs on JVM (Java Virtual Machine) | Runs on C++ engine | | Can change game core code | Can only add/modify behaviours within Mojang’s limits | | Full access to game internals | Sandboxed API |
Ensure file extensions are visible in your operating system settings. Step 2: Extract the Java JAR Assets Navigate to and activate your converted pack
"format_version": "1.20.0", "minecraft:block": "description": "identifier": "custommod:ruby_block" , "components": "minecraft:destructible_by_mining": "seconds_to_destroy": 3.0 , "minecraft:friction": 0.6, "minecraft:light_emission": 0 Use code with caution. Step 6: Compiling and Testing the .mcaddon
Are you targeting for playback?
Written in Java. These modify the game's compiled bytecode directly, allowing for deep logic changes, custom rendering, and complex mechanics.
If you’re primarily converting rather than full mods, PackConverter is an excellent choice. Developed by the GeyserMC team, it converts Java Edition resource packs to Bedrock Edition formats. To bring a Java mod over to Bedrock,
Before diving into the conversion process, it is vital to understand why a "patched" transition is required.
Repeat this process for the Behavior Pack folder. Create another manifest.json file, generate two brand-new UUIDs, and set the module type string to "data" . Step 6: Package into an MCAddon File
