🌍 DynamicPack

A lightweight mod that monitors your resource pack version and updates it automatically.

📖 Documentation

See the GitHub Wiki for full developer documentation, advanced features, and examples.

🎨 Resource Packs Using DynamicPack

These resource packs already use automatic DynamicPack updates:

⚙️ How It Works

Resource pack developers include a metadata file named dynamicmcpack.json inside their pack.
At game launch, DynamicPack checks for updates and automatically downloads the latest version if necessary.

🧩 For Players

Install the mod and enjoy — DynamicPack will handle updates in the background.

🛠 For Developers

If you’d like your pack to update itself automatically, you can choose one of the integration options below.

Create a file named dynamicmcpack.json in your pack:

{ "current": { "version_number": "7.1" // Current version of your resource pack }, "remote": { "game_version": "1.21.1", // Compatible Minecraft version "modrinth_project_id": "better-leaves", // Your Modrinth project slug or ID "type": "modrinth" // Update source type (Modrinth) }, "formatVersion": 1 // Internal config format version }

Create a file named dynamicmcpack.json in your pack:

{ "current": {}, "remote": { "sign_no_required": true, // Optional digital signature — set to true to disable verification "type": "dynamic_repo", // Update source type (Dynamic Repository) "url": "https://adamcalculator.github.io/CursedEveryday/" // Remote repository URL }, "formatVersion": 1 // Internal configuration format version }

Next, create a dynamicmcpack.repo.json file like this:

{ "formatVersion": 1, // Internal schema version "build": 10, // Build number of your current release "name": "CursedEveryday", // Display name of your resource pack "contents": [ { // Metadata block (main information about pack components) "url": "path/to/content.json", "hash": "5e4d4ad1e9714487263c51f5f83c448c0708773a", // SHA1 checksum of content.json "id": "meta", "hidden": true, // Hides this component from user‑facing lists "required": true // Marks this component as mandatory }, { // Example of an additional content section "url": "path/to/content.json", "hash": "6e6739297dac80078bbc4890567f05d4015553db", "id": "cursed", "name": "Cursed content" // Optional friendly display name } ] }

Next, create a separate content.json file for each content section:

{ "formatVersion": 1, // Schema version "content": { "parent": "path/to/parent", // Local folder containing the files "remote_parent": "remote/path/to/parent", // Corresponding path in your Git repo "files": { "path/to/file": { "hash": "ca55daeef2e2d84ccd64608cf889ac321c18d4c2", // SHA1 hash of file "size": 4773 // File size in bytes }, "path/to/file2": { "hash": "336e9f4e6d7d1400d8a308a33e703e8b33ea5434", "size": 54665 }, "path/to/file3": { "hash": "09dae0777de1705e8acd0ff84c0bb6b7e3e22f63", "size": 98592 } } } }

⚠️ Important: These examples use json5, which allows comments (//).
The actual files must be valid .json, so remove comments before use or validate them with this JSON checker.

Advanced features — such as dynamic repositories — are documented in the GitHub Wiki.
