"Converting" a jar to an mcaddon is not an automatic process. It is a creative recreation process. By extracting assets and rewriting logic into JSON/JavaScript, you can successfully bring your favorite Java mod features into the Bedrock edition. If you’d like, let me know: What is the specific Java mod you want to convert? Is it an entity, item, or functional block?
If your goal is to move 3D models or textures from a Java mod to Bedrock, you can use , which is widely recommended by creators on platforms like YouTube .
Java mods often use Java code or specific JSON schemas to generate 3D models. Bedrock relies entirely on a specific JSON geometry format.
Navigate to data/[mod_name]/ . This folder houses recipes, loot tables, and world-generation parameters, usually stored in standard JSON format. Step 2: Convert Visual Assets (Textures and Models) convert jar to mcaddon work
Create a master folder named after your mod. Inside it, create two separate sub-folders: MyMod_BP and MyMod_RP . Step 3: Write the Manifest Files
Go to and activate your pack (it should auto-activate if your dependency UUIDs are set correctly).
Converting JAR to MCADDON requires some technical expertise, but the process can be streamlined with the right tools and guidance. The steps outlined above provide a general framework for conversion, but may require additional troubleshooting depending on the specific JAR file and mod requirements. "Converting" a jar to an mcaddon is not an automatic process
Complex logic, custom world generation, advanced dimensions, and hardcoded Java forge/Fabric API events. Bedrock handles these via JSON files and JavaScript/TypeScript behavior packs. Phase 1: Extracting the Java Mod Assets
Before building the Bedrock version, you need to see what is inside the Java mod.
Below is a comprehensive guide on how to convert components of a Java .jar mod into a working Bedrock .mcaddon . 1. Understanding the Core Difference If you’d like, let me know: What is
Search for "Bedrock equivalent of [Mod Name]" before attempting a manual port. The community has likely already built an MCADDON that does what your JAR does.
Create a dependency link in both manifests so that activating the behavior pack automatically turns on the resource pack.
The general workflow for converting a .jar to a working .mcaddon looks like this:
Ensure your textures are mapped correctly. Bedrock requires texture files to be in .png format, and their resolution should strictly be powers of two (e.g., 16x16, 64x64).
Scroll down to the Experiments tab and turn on options like Beta APIs , Holiday Creator Features , and Custom Biomes/Components depending on what your mod requires.
