Java mods that add complex functionality – such as a custom furnace, a machine GUI, or new crafting mechanics – cannot be directly ported. These features must be using Bedrock’s Scripting API (JavaScript/TypeScript).
Are you aiming to support a or platform (mobile, console, Windows)?
Create a root folder named after your mod. Inside it, create two sub-folders: [ModName] BP (Behavior Pack) [ModName] RP (Resource Pack)
How to Convert JAR to MCADDON: A Complete Step-by-Step Guide
Right-click your .jar file and select (or use 7-Zip/WinRAR). how to convert jar to mcaddon
In contrast, Bedrock Edition add-ons operate very differently:
Right-click and choose (or use 7-Zip to create a standard .zip archive).
[Mod Name] MCAddon/ ├── [Mod Name] BP/ │ ├── manifest.json │ ├── entities/ │ └── items/ └── [Mod Name] RP/ ├── manifest.json ├── textures/ └── models/ Use code with caution. Creating the Manifest Files
To convert a JAR to an MCADDON, you must extract the Java assets and distribute them into the appropriate Resource and Behavior pack structures. Method 1: The Automated Approach (Using Conversion Tools) Java mods that add complex functionality – such
This is the most time-consuming stage. You must manually translate the mechanics from Java code or Java data files into Bedrock data-driven JSON components. 1. Set Up the Bedrock Add-on Structure
Rename the file extension from .zip to (e.g., mymod_conversion.zip becomes mymod_conversion.mcaddon ).
If your mod includes custom mobs, complex logic, or scripting, automated tools will fail. You must build the .mcaddon manually using the Java mod as a blueprint. Step 1: Decompile and Decompress the JAR Change the extension of your mod from .jar to .zip . Extract the ZIP file into a dedicated project folder.
myaddon/ |-- addon.json |-- assets/ | |-- myaddon/ | |-- textures/ | |-- myitem.png | |-- models/ | |-- myitem.json |-- scripts/ Create a root folder named after your mod
Because Bedrock is data-driven, you cannot convert complex, code-heavy Java mods (like Create or Thaumcraft ) automatically. However, you can successfully convert content-focused mods that add blocks, items, entities, world generation, and custom recipes. Step 1: Deconstruct the Java .JAR File
Converting a mod requires translating the logic, assets, and behaviors. This comprehensive guide will walk you through the manual and automated processes of converting a .jar mod into a .mcaddon . Understanding the Architecture: JAR vs. MCADDON
While converting assets is relatively straightforward, some Java mods cannot be perfectly ported to Bedrock:
