Billboard Engine

Install: put billboard-2.0.0.jar into the mods folder, together with Fabric API. Needs Fabric Loader 0.19.5 or newer and Java 25. Optional: Billboard API 0.1.0 or newer for Lua, and CC: Tweaked.

Worlds with Script Boxes from 1.x: install Billboard API before you open them. Without it the Script Boxes are removed from the world when it loads (their files stay in <world>/billboard/scripts/, the blocks don't come back).

The Script Box moved to Billboard API

• The Script Box is now the Lua Box of Billboard API, a separate, optional mod. Same recipe. Without Billboard API the engine works by hand as always: wand, text, scrolling, letter sizes, sign and redstone pulse, redstone punch card, and CC: Tweaked computers. Pictures and clocks need a Lua Box or a CC computer. Billboard API also brings Data Pipes, other machines to drive (signs, the Typestones typewriter), main.lua plus modules for require, and a Network view in the box's screen.
• The engine is a Lua client of type billboard:engine. A box reaches it by touching it or through Data Pipes. engine in a program is the one engine the box reaches; with several, use network.findByName(name). All engine functions are unchanged, drawImage(name) takes an image from the calling box's files.
• Text from a Lua Box: "\183" is still the middle dot, as in CC and the Script Box. A · typed into a UTF-8 file works as well.
• Worlds from 1.x: Script Boxes become Lua Boxes and keep their files; the program is renamed to main.lua.
• /billboard script is gone, use /luabox <pos> restart|stop|status.
• The script* settings are no longer read from config/billboard.properties; Billboard API takes them over into config/billboard_api.properties at its first start.
• Cobalt (the Lua VM) is no longer packed into this mod.
