Realize the idea ：

table surface ＝＝＝》》》 To string ( Here use json library )＝＝＝》》》 Storage ＝＝＝》》》 Read

 

To achieve an end

• Solve the string splicing problem
• In the simplest way table Table stored in file , Convenient for game archiving 、 Game level 、 wait

First step ： take table Table to json Format string

Import header file

local json = require("framework.shared.json")

 

Create a table

 local t = {}

        t.test = "OKOK"

        t.net = "okok"

        t.inner = {}

        t.inner.test = "OKOK8888"

 

local wirtjson =json.encode(t)-- convert to json Format

local readjson =json.decode(wirtjson)-- Convert to the original format before storage

 

Be careful : The following two methods can get the root directory of the project on the current computer

1.  device.writablePath          
2.  device.cachePath  

The second step ： write file , Store and read

  The first method ：lua io library       

Save the file to the root directory of the current project ：

local test = assert(io.open(device.writablePath .. "/formation.lua", "w"))

test:write(wirtjson)

test:close()

 

Read entire file ：

local test = io.open(device.writablePath .. "/formation.lua", "r")

    local readjson= test:read("*a")

    local  table =json.decode(readjson)

    test:close()

 

The second method ：CCUserDefault

Save the file to the root directory of the current project ：

CCUserDefault:sharedUserDefault():setStringForKey("SaveFightArray1", wirtjson)

CCUserDefault:sharedUserDefault():flush()

Read entire file ：

record1 = CCUserDefault:sharedUserDefault():getStringForKey("SaveFightArray1")

local  table =json.decode(record1)
