Beta 1.7. I separated out an old copy of wiki.vg docs which are very useful but don't describe how to actually use half the packets. (Praise be to whoever the "Great Old Ones" are.) Just got it to send a stone & air world and have the client spawn-in, after… too much getting simple things wrong. Used LuaJIT to FFI in libdeflate for chunk encoding to then be very happy you can skip that altogether and just send mass block changes! (Winsnore for the client as I just could not get it to run on my Linux) Everything pure Lua so far, featuring inefficient number→binary en/decoding, and `assert(false)`ing on trying to decode a 64-bit number too large to be safe in a Lua float for now. and I am very grateful to Lars for his float encoder which I've bodged in for now Next step is to handle multiple clients, let them see each other, and then to let people interact with the world…

Promising is entirely the opposite of what you should think of anything I do In typical me fashion this didn't go much further, partly due to me finding a new thing to try and a lot because b1.7.3's protocol is absolute- not very good. I moved onto designing my own protocol and then that went nowhere. I might pick up one of my Classic, Beta, or my own protocols again now you've reminded me of it… just really need to pick a better thing to use for 3D graphics than Löve2D (LöVR maybe… I like the idea of SDL3 but that requires doing 3D from GPU up which I know little about.)
