[GUIDE] creating blueprints manually
Posted: Tue May 14, 2019 5:36 pm
I made a copy-paste mod for 0.16, but i figured out i didn't need to create the blueprint strings myself.
So here's what i found:
Requirements:
https://github.com/jiyinyiyong/json-lua
https://github.com/iskolbin/lbase64
https://github.com/SafeteeWoW/LibDeflate
Example script:
(I didn't work out the JSON part yet, but should be pretty straightforward)
to decode a blueprint-string, simply remove the first character, run base64.decode and then LibDeflate:DecompressZlib

local compressed = LibDeflate:CompressZlib(example_input,{strategy="fixed"}) --level = ?? ... can't figure out the exact algorithm the game uses - but fortunately the game doesn't care which compression is used
compressed = base64.encode( compressed)
compressed = "0"..compressed
game.players[1].cursor_stack.import_stack(compressed)
end)to decode a blueprint-string, simply remove the first character, run base64.decode and then LibDeflate:DecompressZlib
Code: Select all
local test = base64.decode(compressed:sub(2))
test = LibDeflate:DecompressZlib(test)
game.players[1].print(test)
