1.基本語(yǔ)法
a= 5; -- 全局變量
print(a)
local a = 6; -- local局部變量
print(a)
-- if用法 獲得最大值
function max(a,b)
if a>b then
return a
else
return b
end
end
print(max(2,3))
-- for循環(huán)
for var=1, 5 do
print(var)
end
2.表
config = {a="a",b=17} -- 定義時(shí)候賦值
config.name = "hello"
config.num = 13
-- 點(diǎn)跟中括號(hào)是一樣
config["score"] = 78
print(config.a)
print(config.name)
print(config["score"])
for key, var in pairs(config) do
print(key,var)
-- a a
--num 13
--name hello
--b 17
--score 78
end
3.數(shù)組
arr = {1,2,3,"hello"} -- 數(shù)組角標(biāo)是從1開(kāi)始，不是從0
