Lua Programming

编程就像给计算机一步步下指令，让它做事情。就像告诉朋友如何搭建乐高房子一样，你为计算机编写代码以供其执行。在Roblox Studio中，你使用Lua编程语言来创建游戏并实现你的想法。Lua简单而强大，非常适合初学者。

"Hello, world!"

function sayHello()
  print("Hello, world!")
end

local message = "Hello, Roblox!" 
print(message)

Empty

nil	a = nil

boolean	b = true

number	n = 1

string	s = 'abc'

table	t = {a, b, c}

function	foo = function(x) return 2*x end

userdata	u = some_C_struct

thread	co = coroutine.create( function () print('hi') end )

local greeting = "Hello" 
local name = "Roblox" 
print(greeting .. ", " .. name)

local age = 10 
print("I am " .. age .. " years old")

local x = 10 
local y = 20
print(x + y)

local a = 5 
local b = 3 
print(a * b)

local number = 10 
if number > 5 then  
   print("Number is greater than 5") 
else 
   print("Number is 5 or less") end

for i = 1, 5 do 
   print("Iteration " .. i) 
end

function greet(name) 
   print("Hello, " .. name) 
end 
greet("Roblox")
greet("Game")
