Lua面向对象 --- 单例

GameManager.lua:

--单例模式是利用一个全局表来实现的

GameManager = {}

Manager = {__index = GameManager}

function GameManager:new()
    local self = {}
    setmetatable(self,Manager)
    return self
end

function GameManager:ShowName()
    print("the is an singleton")
end

Main.lua:

require "GameManager"

gm = GameManager:new()

gm:ShowName()

--[[
运行结果:
the is an singleton
--]]
