Computer

All computer tiers ingame

Computers come in 5 different tiers, namely Wood, Iron, Diamond, Netherite and finally Creative, though that tier is not available in survival. These tiers only differ in the amount of inventory slots and computer speed. In the future, tiers will also impact the amount of usable memory.

Netherite computer gui

The computer is what provides most of the core Lua components and is where you place item-components, such as Hard Disk Drives or Floppy Disks. You can start the computer by pressing the power button shown in the gui-image. Similarly, to forcefully stop a computer you can press the same button. Both actions can also be performed by shift-right-clicking the computer with an empty hand, which then either starts or stops it, depending on the current state.

The lit indicator on the front of the computer indicates the run-state. A computer can be in one of the following states:

Run states

Color	State
Red - On	Stopped
Red - Blinking	Crashed
Green - On	Running
Green - Blinking	Currently unimplemented, but will indicate Working in the future

Keep in mind that starting the computer initially may take some time; give it a few seconds. This is because the JLuaVM is warming up and will be fixed in future. Successive runs are much faster as the Lua code is already compiled and loaded from one of the two compilation caches (the second one even persists across world reload).

Provided Component

The computer block provides access to the computer component. This component includes the following properties:

ComputerUD component properties

Name	Type	Read/Write	Description
uefi	UefiUD	READ	Provides access to the UEFI located on the Mainboard installed in the current computer's inventory.
nvram	NvramUD	READ	Provides access to the NVRAM located on the Mainboard installed in the current computer's inventory. This can be used to store data that persists across reboots and does not require a filesystem. See NVRAM for more information.
tpm	not yet implemented	READ	In the future will provide access to the Trusted Platform Module.

ComputerUD component methods

Name	Type	Description
:beep(freq:number, duration:number)	void	Plays a hearable sound with frequency freq and duration duration, hearable near the computer block.
:getMachineEvent()	any[]	Dequeues and returns the next item in the computer's event queue. Example return values are {"keyPressed", "\n", 257, 28, 0} when pressing the ENTER key in a gui or {nil} when there is no queued event. All possible events are listed in section #Machine Events.
:beep(freq:number, duration:number)	void	Plays a hearable sound with frequency freq and duration duration, hearable near the computer block.
