OpenComputers II is a Minecraft mod adding virtual computers to the game. These computers run a virtual machine emulating a 64-Bit RISC-V architecture capable of booting Linux. On top of this, a high-level Lua API is provided to communicate with various devices in the game world. This enables adding virtual devices using a simple, Java-friendly API, without having to implement actual kernel drivers.
This mod is a successor to OpenComputers. At least in spirit. While many of the implementation details have changed quite dramatically, the core concepts of customizable hardware, persistence and sand-boxing are shared.
For documentation on how the to get computers up and running, and how to use them, see the documentation. It is available as a manual item in the game.
While the mod isn't quite yet ready for release due to some remaining technical and usability issues, the API should be mostly stable at this point. For most people the high level device API will be sufficient, and is much more accessible. It centers around the RPCDevice. For a sample block implementation, see the redstone interface. For a sample item implementation, see the sound card. If you wish to dive deeper, and provide emulated hardware that requires a Linux driver, this centers around the VMDevice. For a sample block implementation, see the disk drive. For a sample item implementation, see the network card.
To build this project, credentials for the Github Package Repository must be set up once on your machine (see
the documentation for more information). In short, you'll want to add your username and a
public access token with read:packages permissions into your ~/.gradle/gradle.properties. The properties must be
named gpr.user and gpr.key.
