二、lua点和冒号区别

概述看程序的时候，经常看到点和冒号用来调用function.虽然知道什么含义.但还是记录一下 点的例子: local CandyCrashItem = {}CandyCrashItem.__index = CandyCrashItemfunction CandyCrashItem.printNum(num) print(num)endCandyCrashItem.printNum(1) 看程序的时候，经常看到点和冒号用来调用function.虽然知道什么含义.但还是记录一下

点的例子:

local CandyCrashItem = {}CandyCrashItem.__index = CandyCrashItemfunction @[email protected](num)    print(num)endCandyCrashItem.printNum(1)

结果:1

冒号的例子:

local CandyCrashItem = {}CandyCrashItem.__index = CandyCrashItemfunction @H_404_17@CandyCrashItem:printNum(num) @H_404_17@print(num) @H_404_17@end @H_404_17@CandyCrashItem:printNum(1)

结果:1

点调用冒号的方法:

local CandyCrashItem = {}CandyCrashItem.__index = CandyCrashItemfunction @H_404_17@CandyCrashItem:printNum(num)    print(num)endCandyCrashItem.printNum(CandyCrashItem,1)

结果:1

点调用冒号方法错误例子:

local CandyCrashItem = {}CandyCrashItem.__index = CandyCrashItemfunction @H_404_17@CandyCrashItem:printNum(num)    print(num)endCandyCrashItem.printNum(1,CandyCrashItem)

结果:table: 0x7fa222f04f50

结论:
冒号方法是对点方法的封装

:function(x)=.@H_404_17@function(self,x)
