Run this GDScript:
if !FileAccess.file_exists("res://luajit.elf"):
var buffer = Sandbox.download_program("luajit")
fa = FileAccess.open("res://luajit.elf", FileAccess.WRITE)
fa.store_buffer(buffer)
fa.close()
var luajit = Node.new()
luajit.set_script(load("res://luajit.elf"))Add a new function to the Lua API:
luajit.add_function("test", func(name): return "Test " + str(name) + " called!")
luajit.add_function("add", func(a, b): return a + b)Execute Lua script:
luajit.run("""
print(test(1))
print(add(333, 666))
function fib(n, acc, prev)
if (n < 1) then
return acc
else
return fib(n - 1, prev + acc, acc)
end
end
print("The 500th fibonacci number is " .. fib(500, 0, 1))
""")
