2. How to compute hash:

hash = MD5(gamedata["data"] + "BonusItemProtoData");

3. ^_^

@roycef:

The way you use the gamedata variable it's an object, so you need to convert it to a string first (JSON.stringify())

This one is working: http://jsfiddle.net/XLYDe/74/
Just copy in your modified gamedata.txt content and run it!

If I would like to add coins and gems according to my requirement for e.g. 10000 coins and 2000 gems then what should I write in the hash and in the remaining coding. Please tell me..
And also what is MD5.

Thanks..
It Works..!
