I haven't written a blog for a long time. I 've written some bad stuff before. Sorry. This time I will introduce some new features of quick-x quick-cocos2d-x.

Quick-x Data Encryption

I. Data Encryption

As long as quick encapsulation is used

Local crypto = require ("framework. crypto") -- algorithm encryption and decryption

To make

Function crypto. encryptxxtea (plaintext, key)
Plaintext = tostring (plaintext)
Key = tostring (key)
Return cccrypto: encryptxxtea (plaintext, String. Len (plaintext), key, String. Len (key ))
End

This is something in the framework. If you are interested, take a look.

Here, my encrypted data is decrypted, read, and encrypted, and saved only when modified, so that the encryption field cannot be changed for the Ghost artifact and so on.

Local key_coin = "coin"

Local encodecoin = crypto. encryptxxtea (0, key_coin) -- gold coins

-- Gold coin ----------

Local writecoin = function ()

Userdefault: setstringforkey (key_coin, encodecoin)

End

Function gamedata: getcoin ()

Return tonumber (crypto. decryptxxtea (encodecoin, key_coin ))

End

Function gamedata: setcoin (value)

Local coin = self: getcoin () + Value

If coin <0 then returnend

Encodecoin = crypto. encryptxxtea (coin, key_coin)

Writefuncs [key_coin] = writecoin

Eventmanager: dispatchevent ({name = event_data, kind = player. coin, value = coin })

Return coin

End
