Convert Jar To Mcpack Top
A behavior pack (.mcpack with type: "data") can copy simple functions, but the commands differ.
Example manifest.json for behavior:
"format_version": 2,
"header":
"name": "Converted Behavior",
"uuid": "uuid-1",
"version": [1, 0, 0]
,
"modules": [
"type": "data",
"uuid": "uuid-2",
"version": [1, 0, 0]
],
"dependencies": [
"uuid": "uuid-of-your-resource-pack",
"version": [1, 0, 0]
]
Extract the assets to a new folder
Create Bedrock resource pack structure:
YourPack/
├── manifest.json
├── pack_icon.png
├── textures/
├── models/
└── sounds/
Write a manifest.json (example):
"format_version": 2,
"header":
"name": "Converted Java Pack",
"description": "Textures from Java mod",
"uuid": "generate-a-unique-uuid-here",
"version": [1, 0, 0],
"min_engine_version": [1, 19, 0]
,
"modules": [
"type": "resources",
"uuid": "another-unique-uuid-here",
"version": [1, 0, 0]
]
Generate UUIDs from uuidgenerator.net
Map Java paths to Bedrock paths (manual – very tedious): convert jar to mcpack top
Zip the folder → rename .zip to .mcpack
Once you have your folder ready:
# On Windows:
Select folder → Send to → Compressed (zipped) folder → rename .zip to .mcpack
Example of manifest.json:
"name": "My Add-on",
"description": "An example add-on.",
"version": "1.0.0",
"uuid": "YOUR_UUID_HERE",
"min_engine_version": "1.16.0"
Focus only on assets/ for Bedrock resource packs.
For simple data packs: data/(namespace)/ might have functions/ (but syntax differs).
You cannot simply "rename" or "convert" a Java mod to a Bedrock add-on.
Java Edition and Bedrock Edition are coded in different languages (Java vs. C++) and use completely different APIs.
What you can do is:
If you want to convert world saves: Java worlds → Bedrock is possible with third-party tools, but mods are not automatable.
