Download MinecartsLoadChunks For Minecraft 1.20, 1.21

Minecarts are now capable of traversing terrain seamlessly, as they no longer get hindered by the borders of unloaded chunks.

Minecarts Load Chunks Mod

This Fabric mod is designed to prevent minecarts from halting at the edges of unloaded chunks by actively loading them as they travel. Regardless of the type, whether it’s a standard, chest, furnace, or hopper minecart, this mod ensures a smooth transport experience across your Minecraft landscape.

Key Features

Automatic Chunk Loading: Automatically loads a 3×3 grid of chunks surrounding a moving minecart, eliminating issues related to chunk borders.
Compatible with All Minecart Types: Works seamlessly with regular minecarts, chest minecarts, furnace minecarts, and hopper minecarts.
Tick-Based Expiry: Chunks remain loaded for a duration of 30 seconds (600 ticks) after the minecart has departed, with adjustments possible in the configuration file.
Persistent Chunk Data: Loaded chunks are saved based on each world instance and restored upon server restart, preventing minecarts from being stranded even across server reboots.

How It Operates

The mod continuously monitors for all types of minecarts (including regular, chest, furnace, and hopper carts) on every server tick.
Upon detecting a minecart with non-zero velocity, it logs the tick and ensures that a 3×3 grid around the minecart’s current location is loaded.
The loaded chunks will remain active for a duration of 30 seconds (600 ticks).
Persistent Data Storage: Chunk data is securely saved in each world’s save directory and is reinstated when the world is reloaded, preventing minecarts from becoming stranded.
