Xml Serialization - Does not save anything.
Hey guys, Can anyone help me? I have been trying to use Xml serialization method to Save/Load the unlockable Characters in the game.
The code is working and it does not give any errors. The code does save and load successfully. But it does not really save the desired values.
I think I know where I am going wrong, but I really can't figure out what the solution can be.
Here is what's inside the xml file that is saved :
<?xml version="1.0" encoding="utf-8"?>
<Character xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<price>0</price>
<opened>false</opened>
</Character>
In Details:
Basically what the script does is that when the user buys a new character, there is a bool called "opened", the script basically sets the bool value to be true. Now I need that bool value to be saved.
I am really sorry for the long code dump.
their is another script which basically callbacks this script. I have not attached that.
Here is the code:
