Let your turtles and computers keep working when you’re not around.

This mod adds a chunk loader peripheral block for stationary ComputerCraft computers, and a turtle upgrade that makes chunk loading follow your turtle as it moves.

Optional admin password can be required to enable.

Server-side config lets you limit the number of active chunks per device.

Requirements

Minecraft 1.12.2
Forge Loader 14.23.5.2768+ (Tested on: 14.23.5.2860)
ComputerCraft 1.80pr1

Features

Chunk Loader Peripheral Block

Place the Cc Chunk Loader block on any side of a Computer or Advanced Computer.
From Lua, you can enable permanent chunk loading for the chunk where the computer is located.
See LUA script below

Turtle Upgrade

Merge the Cc Turtle Chunk upgrade onto the left or right side of a Turtle or Advanced Turtle.
From Lua, enable permanent chunk loading around the turtle. The loaded area automatically follows the turtle as it moves.
See LUA script below

Configurable Radius

Default radius = 0 (loads the current chunk only, with automatic chunk swapping as the turtle moves).
Radius can be increased:
- 1 = 3×3 chunks
- 2 = 5×5 chunks
- etc.
