1. Purpose

This small collection of ComputerCraft LUA APIs and scripts was used on the Minecraft servers on Random-Host.tv. They may not be very fancy and potentially buggy, but they did the job back in 2015.

You can use them if you want, but don't expect any support.

2. Available Programs

These programs make heavy use of ComputerCraft APIs.

Even though most of the program's code should be self-explanatory, you may wish to read the Available APIs section to learn more about the APIs used within these programs and how those APIs are used to configure the behavior of each individual program.

The following programs are included:

• layer
  Mines a layer of blocks such as obsidian.

• reactor
  Controls a passively cooled BigReactors reactor.

• strip
  Classical strip mining program.

3. Available APIs

An API (Application Programming Interface) is a collection of code that, rather than being run directly by the user as a program, is meant to be used by other programs.

To learn more about ComputerCraft APIs, please refer to the Computercraft Wiki's APIs category.

The following APIs are included:

3.1. fuel

Provides functions for auto-refueling turtles.

This API is primarily a dependency of the strip API.

• fuel.check()

  Checks the fuel level of the turtle and attempts to refuel using the first suitable fuel item found in the turtle's inventory.

3.2. gui

Provides functions for printing GUI items on monitors.

This API is primarily a dependency of the reactor API but could be used in other programs as well.

• gui.setTextScale(float scale)

  Sets the text scale to be used for rendering text.

  Default: 0.5

• gui.setDefaultBackgroundColor(number color)

  Sets the default background color for rendering GUI elements.

  Default: colors.black

• gui.setDefaultForegroundColor(number color)

  Sets the default foreground color for rendering GUI elements.

  Default: colors.white

• gui.setBarBackgroundColor(number color)

  Sets the background color for bar GUI elements.

  Default: colors.green

• gui.setBarForegroundColor(number color)

  Sets the foreground color for bar GUI elements.

  Default: colors.white

• gui.setStatusBarActiveBackgroundColor(number color)

  Sets the background color for active status bar sections.

  Default: colors.green

• gui.setStatusBarActiveForegroundColor(number color)

  Sets the foreground color for active status bars section.

  Default: colors.white

• gui.setStatusBarInactiveBackgroundColor(number color)

  Sets the background color for inactive status bar sections.

  Default: colors.gray

• gui.setStatusBarInactiveForegroundColor(number color)

  Sets the foreground color for inactive status bars section.

  Default: colors.white

• gui.setMonitor(string monitorPosition)

  Sets the monitor to be used.

• gui.getMonitor()

  Returns the monitor to be used.

• gui.centerText(string text)

  Renders the given text horizontally centered.

• gui.displayTitleBar(string text)

  Renders a title bar with the given text.

• gui.displayFooterBar(string text)

  Renders a footer bar with the given text.

• gui.displayStatusBar(number x, number y, number length, string value, string label)

  Renders a colored status bar of the given length.

3.4. l10n

Provides functions for loading localization strings.

This API is primarily a dependency of all APIs which print text.

• l10n.setLanguage(string language)

  Sets the language code for the localization to be loaded.

  Default: 'en'

• l10n.getLanguage()

  Returns the language code for the localization to be loaded.

• l10n.load(string name)

  Loads the localization file identified by the given name. This will usually be the name of the API which will be using the localization strings.

3.5. reactor

Provide functions for controlling a BigReactors reactor.

• reactor.setShutdownThreshold(number threshold)

  Sets the shutdown threshold. This is the buffer fill level at which the reactor will automatically shut down.

  Default: 0.75 (75%)

• reactor.setStartupThreshold(number threshold)

  Sets the startup threshold. This is the buffer fill level at which the reactor will automatically start up when operating in "auto" mode.

  Default: 0.50 (50%)

• reactor.setShowRodLevelBars(bool enable)

  Sets if control rod level bars should be shown in the GUI.

  Default: true

• reactor.setEnableRedstoneControl(bool enable)

  Sets if auto startup requires a redstone signal. Setting this to true will cause the computer which the program is running on to require a redstone signal in addition to the reactor's internal buffer fill level being below the configured startup threshold before the reactor is started.

  This can be used to delegate auto startup control to an external device such as Ender IO's Power Monitor.

  Default: false

• reactor.setMonitorName(string monitor)

  Sets the name of the monitor which the GUI should be displayed on.

  Default: 'top'

• reactor.setReactorName(string reactor)

  Sets the name of the reactor to be controlled.

  Default: 'BigReactors-Reactor_0'

• reactor.setRedstoneControlInput(string side)

  Sets redstone control input side. This is the side from which the redstone signal for the external redstone control will be provided to the computer.

  See reactor.setEnableRedstoneControl() above for more information.

  Default: 'back'

• reactor.setOperationMode(string mode)

  Sets the operation mode. This sets the initial mode the control program operates in (either 'auto' or 'manual') when the computer is booted.

  The operation mode can be changed at runtime via the GUI.

  Default: 'manual'

• reactor.run()

  Runs the reactor control program main loop. The program will keep running until the user hits a key or terminates the program by holding [CTRL]+[T].

3.6. strip

Provides functions for strip mining using turtles.

• strip.setStripHeight(number height)

  Sets the height of the strip mining tunnels.

  Default: 4 (4 blocks)

• strip.setStripLength(number length)

  Sets the length of the strip mining tunnels. This must be an even number.

  Default: 40 (40 blocks)

• strip.setStripCount(number count)

  Sets the amount of tunnels to dig.

  Default: 4

• strip.setStripInterval(number interval)

  Sets the interval of the tunnels.

  Default: 3 (every 3 blocks)

• strip.setEnableTorches(bool enable)

  Enables or disables placing of torches.

  Default: true

• strip.setTorchSlot(number slot)

  Sets the storage slot for torches.

  Default: 16 (inventory slot 16, counted from left to right)

• strip.setTorchInterval(number interval)

  Sets interval for placing torches.

  Default: 3 (every 3 blocks)

• strip.run()

  Runs the strip mining program with set parameters.

  When the program has finished, the turtle will remain at the last position.

3.7. torch

Provides functions for placing torches.

This API is primarily a dependency of the strip API.

• torch.setSlot(number slot)

  Sets the storage slot for torches.

  Default: 16 (inventory slot 16, counted from left to right)

• torch.place(bool placeUp)

  Places a torch. If placeUp is set to true, the torch will be placed one block "above" the turtle's front side, otherwise it will be placed one block "below".
