Lua in Games 3/3 – Lua Flavor
● I tried porting of LuaUnit ( https://github.com/bluebird75/luaunit )
● Game engines are frozen and modified script languages ( Core => Lua 5.3 flavor, Roblox's
Luau => Lua 5.1 flavor ).
● Core: "package library" feature is missing, not used by LuaUnit
● Core: Different implementation of script file inclusion ( "require" ). No nested file
inclusion.
lu = nil
if (CoreObject) then
local propLuaunit = script:GetCustomProperty("luaunit")
lu = require(propLuaunit)
else
lu = require("luaunit")
end
