Minecart

Minecart, the lean railway transportation automation system

Minecart is based on carts, which is based almost entirely on the mod boost_cart [1], which itself is based on (and fully compatible with) the carts mod [2].

The model was originally designed by stujones11 [3] (CC-0).

Cart textures are based on original work from PixelBOX by Gambit (permissive license).

Minecart Features

The mod Minecart has its own cart (called Minecart) in addition to the standard cart. Minecarts are used for automated item transport on private and public rail networks. The mod features are:

a fast cart for your railway or roller coaster (up to 8 m/s!)
boost rails and speed limit signs
rail junction switching with the 'right-left' walking keys
configurable timetables and routes for Minecarts
automated loading/unloading of Minecarts by means of a Minecart Hopper
rail network protection based on protection blocks called Land Marks
protection of minecarts and cargo
Minecarts run through unloaded areas (only the stations/hopper have to be loaded)
Extra Minecart privs for rail workers
Ingame documentation (German and English), based on the mod "doc"
API to register carts from other mods
chat command /mycart <num> to output cart state and location
Command interface for Techage (Lua and ICTA) and for Beduino Controllers

Technical Background

The Minecart can "run" through unloaded areas. This is done by means of recorded and stored routes. If the area is unloaded the cart will simply follow the predefined route until an area is loaded again. In this case the cart will be spawned and run as usual.

Introduction

Place your rails and build a route with two endpoints. Junctions are allowed as long as each route has its own start and endpoint.
Place a Railway Buffer at both endpoints. (buffers are always needed, they store the route and timing information)
Give both Railway Buffers unique station names, like Oxford and Cambridge
Place a Minecart at a buffer and give it a cart number (1..999)
Drive from buffer to buffer in both directions using the Minecart(!) to record the routes (use 'right-left' keys to control the Minecart)
Punch the buffers to check the connection data (e.g. "Oxford: connected to Cambridge")
Optional: Configure the Minecart waiting time in both buffers. The Minecart will then start automatically after the configured time
Optional: Protect your rail network with the Protection Landmarks (one Landmark at least every 16 nodes/meters)
Place a Minecart in front of the buffer and check whether it starts after the configured time
Check the cart state via the chat command: /mycart <num> <num> is the cart number, or get a list of carts with /mycart
Drop items into the Minecart and punch the cart to start it, or "sneak+click" the Minecart to get cart and items back
Dig the cart with 'sneak+click' (as usual). The items will be drop down.
To retrieve lost carts, use the chat command: /stopcart

Command Interface

Techage ICTA Controller

The ICTA Controller support the conditions:

"read cart state" (function returns "stopped" or "running")
"read cart location" (function returns the distance or the station/buffer name)

See help page of the ICTA controller block.

Techage Lua Controller

The Lua controller support the functions:

$cart_state(num) (function returns "stopped" or "running")
$cart_location(num) (function returns the distance or the station/buffer name)

See help page of the Lua controller block.

Cart Terminal

The Cart Terminal has a Techage command interface with the commands:

Command	Data	Description
`state`	<cart-ID>	Returns `unknown`, `stopped`, or `running`
`distance`	<cart-ID>	Returns the distance from the cart to the Cart Terminal

Beduino Controller

The Cart Terminal has a Beduino command interface with the commands:

Command	Topic	Data	Response	Description
State	129	[cart-id]	[state]	Returns 0 = UNKNOWN, 1 = STOPPED, 2 = RUNNING
Distance	130	[cart-id]	[distance]	Returns the distance from the cart to the Cart Terminal
