Lua面向对象 --- 继承

工程结构:

BasePlayer.lua:

1 BasePlayer = {}
2 
3 BasePlayer.root = "BasePlayer"
4 
5 function BasePlayer:ShowBaseName()
6     print("ShowBaseName : BasePlayer")
7 end
8 
9 return BasePlayer

Player.lua:

 1 require "BasePlayer"
 2 
 3 Player = {}
 4 
 5 
 6 function Player:new()
 7     setmetatable(Player,{__index = BasePlayer})
 8 
 9     self = {}
10     setmetatable(self,{__index = Player})
11     return self
12 end
13 
14 function Player:ShowPlayerName()
15     print("ShowPlayerName : Player")
16 end
17 
18 return Player

Main.lua：

 1 require "Player"
 2 
 3 testPlayer = Player:new()
 4 
 5 print(testPlayer.root)
 6 testPlayer:ShowBaseName()
 7 testPlayer:ShowPlayerName()
 8 
 9 --[[
10 运行结果:
11 BasePlayer
12 ShowBaseName : BasePlayer
13 ShowPlayerName : Player
14 --]]
