| Java Asset | Bedrock Equivalent |
|------------|--------------------|
| PNG textures | Same (rename to standard names, resize if needed) |
| .obj or .json block models | Bedrock JSON block model (different format) |
| .ogg sounds | .ogg or .fsb in sounds.json |
| Loot tables (loot_tables/) | Similar structure, different syntax |

There is no automated way to convert a Java .jar mod into a Bedrock .mcaddon file. Because Java Edition and Bedrock Edition are built on completely different programming languages (Java vs. C++) and use entirely different rendering and behavior systems, a .jar cannot simply be "patched" or repackaged into an addon.
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
To get started, you will extract the original textures, models, and sounds from the Java .jar file to use as a baseline for your Bedrock addon.
Locate the .jar file: Find the Java mod file you wish to port.
Unpack the archive: Change the file extension from .jar to .zip or use an extraction tool like 7-Zip. how to convert jar to mcaddon patched
Grab the assets: Open the extracted folder and navigate to assets/modid/ (where "modid" is the name of the mod). Copy the textures, models, and sounds folders to a new workspace on your computer. 🎨 Step 2: Convert the Assets for Bedrock
Bedrock Edition handles textures and entity models differently than Java. You must adapt these files so the game can read them properly. For Resource Packs (Textures & Models)
Textures: Java uses individual .png files that usually map directly, but you may need to reorganize the folders to match the Bedrock directory (textures/blocks, textures/items).
Entity Models: Java entity models (often written in .java or .json for Geckolib) are formatted differently than Bedrock's geometry files. Use a 3D modeling tool like Blockbench to import your Java models and export them specifically as Bedrock Geometry (.geo.json). 💻 Step 3: Recreate Mod Behaviors (Scripting & JSON)
This is where the actual "conversion" happens. You cannot use the Java code. You must look at what the Java mod does and code it from scratch for Bedrock.
Component System: Bedrock uses a component-based JSON system for entity behaviors. Map out the behaviors from the Java mod (e.g., custom health, movement speed, or attack damage) and write them into Bedrock behavior files inside a behavior_packs folder. There is no automated way to convert a Java
Bedrock Scripting API: For complex logic that JSON cannot handle (like custom UI or advanced magic systems), you will need to use Bedrock's JavaScript-based Scripting API. Read the Java mod's source code to understand its math or logic, and rewrite those functions in JavaScript. 📦 Step 4: Package into an .mcaddon
Once you have created both your Resource Pack (visuals) and your Behavior Pack (logic), you need to combine them into a single installable file. ZIP To MCADDON Tutorial for minecraft mods made easy!!
Converting a Java .jar file to a Bedrock .mcaddon is a complex task because Java and Bedrock use different programming languages (Java vs. C++) and rendering engines. In this context, "patched" typically refers to using a modified version of Minecraft Bedrock (like Minecraft Patched PE) that restores features like custom shader support or third-party script compatibility. How to Convert JAR to MCAddon (Step-by-Step)
Since there is no "one-click" tool to fully convert code-heavy Java mods to Bedrock, the process is split between simple asset conversion and manual code rebuilding. 1. Convert Assets (Textures & Models)
If your .jar file contains textures or 3D models, you can port these parts relatively easily.
Converting a JAR file to a Minecraft Addon (MCADDON) format, especially if you're looking to patch or modify existing addons, involves a few steps. This guide assumes you have a basic understanding of Minecraft modding, Java, and file management. you will extract the original textures
This is the only method that creates an .mcaddon that actually contains the original .jar file. It uses a hacked Bedrock launcher to run a Java Virtual Machine (JVM) inside Bedrock.
This is the most critical phase. You must translate the logic from Java to Bedrock formats.
| Feature | Java Format | Bedrock Format | Action Required |
| :--- | :--- | :--- | :--- |
| Items/Blocks | ModItems.register() (Java Code) | behavior_pack/items/*.json | Create JSON definition files manually. |
| Recipes | RecipeSerializer or .json | behavior_pack/recipes/*.json | Reformat JSON structure to Bedrock standard. |
| Entities | EntityType.Builder | behavior_pack/entities/*.json | Create entity JSON files and define behaviors. |
| Logic | Java Classes | scripts/main.js | Rewrite logic using the Minecraft Script API (Gametest). |
| Models | .java model files (Code-based) | .geo.json | Import Java model into Blockbench -> Export as Bedrock Geometry. |
If you have spent any time in the Minecraft modding community, you know the golden rule: Java Edition mods (.jar) do not work on Bedrock Edition (.mcaddon). Or, at least, they didn’t used to.
Thanks to a series of community-driven tools, proxy servers, and "patcher" scripts, it is now technically possible to convert a Java .jar file into a Bedrock .mcaddon file. However, this is not a "drag and drop" process. It requires reverse engineering, asset repacking, and a heavy dose of patience.
This 2,500+ word guide will explain exactly how to convert JAR to MCADDON patched, covering the theory, the tools, the step-by-step process, and why 90% of Java mods will still fail even after a successful conversion.
