Create Kart - Version 3.0.0 : Fabric 1.21.1 Port!

[DevNote]

Hello everyone! This is a massive milestone for the mod: after months of hard work building upon the foundation of version 2.5.0, here is officially version 3.0.0, introducing the very first port to Minecraft 1.21.1 with Fabric (alongside the unofficial Blockfield Create 6.0 port)

The mod has been completely restructured to adopt a clean multi-loader architecture while faithfully preserving all the handling, drift mechanics, physics, and balancing of the previous version. Enjoy the complete, modernized Create Kart driving experience on the latest versions of the game!

[Additions]

🧱 Modern Environment & Compatibility

- Minecraft 1.21.1 & Fabric: The mod now runs natively on Fabric (requires Fabric API, GeckoLib 4.9.3+, Forge Config API Port, and the unofficial Blockfield Create 6.0 port).

- Multi-Loader Architecture: The code has been thoroughly cleaned and refactored to cleanly separate shared logic from loader-specific implementations, ensuring much better long-term stability.

🏎️ Handling, Physics & Fidelity (Inherited from 2.5.0)

- Complete Drift & Boost System: Experience the drift mechanic with 3 charge levels (ranging from smoke to blue sparks) and rewarding speed boosts upon releasing at the right time.

- Dynamic Drift Camera: The camera smoothly follows your movements during tight turns (can be disabled in client configuration).

- Refined Fuel System: Coal and charcoal (+500) as well as coal blocks (+4500) fuel your tank with absolute precision, complete with the under-revving mechanic during empty tank states.

🛠️ Tools & Interactions

- Create Wrench Dismantling: Use your wrench to individually retrieve each kart component by holding Shift + Right-Click (engine, wheel, exhaust, seat, bumper, chassis).

- Interactive Tire Piles: The wrench also allows you to remove and recover tires one by one from tire stacks.

- Interactive Seat Block: Sit comfortably on seat blocks placed in the world (one player per seat, Shift to dismount).

⚙️ Server Configuration Migration

- Dedicated Server Config: Driving settings are now entirely managed via the server configuration file (config/create_kart-server.toml or inside your world's serverconfig/ folder).

🎮 Behavior & Safety

- Abandoned Karts: Karts without a driver stop immediately (no more infinite autonomous rolling, wasted fuel, or accidental injuries), and empty karts can no longer be pushed around by walking players.

- Multiplayer Security: Physics, fuel, and drift calculations are fully handled by the server to completely eliminate desynchronization and position lags between players.

[Bug Fixes]

🌐 Network & Rendering Stability

- Network Protocol 5: Implementation of a robust new network protocol handling entity data synchronization seamlessly without redundant packets.

- GeckoLib Animations: Integration of GeckoLib 4.9.3 with rendering fixes to eliminate any model flickering during non-drift states.

- Miscellaneous Fixes: Adjusted real reverse-gear steering behavior, corrected idle engine sound behavior, and resolved various multiplayer interaction conflicts.

⚠️ Breaking Changes

- Network Protocol 5: The server and all connecting players must strictly run version 3.0.0 (connections using older protocols will be rejected).

- Required Dependencies: Strictly requires Minecraft 1.21.1, Fabric Loader, Fabric API, GeckoLib 4.9.3+, Forge Config API Port, and Create (Blockfield fork).
