hi
with the new drill sprite with the factorio version 0.18.31,
i change some things in entity.lua
i use the base file lua to copy/paste the graphic set element
i add some files in prototypes mod folder
require ("prototypes.entity.demo-pipecovers")
local hit_effects = require ("prototypes.entity.demo-hit-effects")
local sounds = require("prototypes.entity.demo-sounds")
if not data.is_demo then
require ("prototypes.entity.assemblerpipes")
end
if you want the zip file, email me to hebeldark@gmail.com
