CC-Holo
by Lemmmy
CC-Holo gives CC: Tweaked computers a holographic display peripheral, letting programs draw 2D and 3D objects in the world.
What it does
Holograms are drawn by a Lua peripheral that a computer controls through CC: Tweaked. Admins and mapmakers can use the display to build interactive setups, and anybody with creative mode permissions can place the peripheral and command blocks can drive it. Objects appear as 2D or 3D shapes in the world rather than on a player's screen.
The mod also provides basic key capture during gameplay, and a more detailed mouse and keyboard capture mode that opens a GUI. Two demo programs in the source show typical usage and cover most of the available functions, so the source code is the reference for the full function list. CC-Holo is built on the CC: Tweaked peripheral provider, and it is published for Forge 47.4.9 on Minecraft 1.20.1, released under the MIT License and open source.
Installation needs a compatible CC: Tweaked release on Forge. A server running it needs every connecting player to have it too. Public links cover the source code, issue tracker and wiki.
