My brother and I are making a couple games at the moment for PC, and we had thought of something that we were wondering if it is possible. Since PlayerPrefs seem to be the most common way to save variables, and therefore your game, we were curious as to if you could access another games PlayerPrefs in your own one.
An example of this would be if we made ‘Mr X Run and Gun’ and ‘Mrs X Stab and Grab’, could a variable from the Mr X game called “CH1_Bonus” be accessed in the Mrs X game?
This doesn’t have to be exclusive to the PlayerPrefs, but so far we haven’t found anything that could be worked like this.
EDIT: I forgot to mention that we are scripting in C# as well if that helps.
In theory, this is highly possible.
Taken from the wiki:
On Mac OS X PlayerPrefs are stored in ~/Library/Preferences folder, in a file named unity.[company name].[product name].plist, where company and product names are the names set up in Project Settings. The same .plist file is used for both Projects run in the Editor and standalone players.
On Windows, PlayerPrefs are stored in the registry under HKCU\Software[company name][product name] key, where company and product names are the names set up in Project Settings.
On Linux, PlayerPrefs can be found in ~/.config/unity3d/[CompanyName]/[ProductName] again using the company and product names specified in the Project Settings.
On Windows Store Apps, Player Prefs can be found in %userprofile%\AppData\Local\Packages[ProductPackageId]>\LocalState\playerprefs.dat
On Windows Phone 8, Player Prefs can be found in application’s local folder, See Also: Directory.localFolder
On Android data is stored (persisted) on the device. The data is saved in SharerPreferences. C#/JavaScript, Android Java and Native code can all access the PlayerPrefs data. The PlayerPrefs data is physically stored in /data/data/pkg-name/shared_prefs/pkg-name.xml.
So, with that said, if you use some file reader magic, and check to see if the location exists, then you can pull the playerprefs file, and parse it.
