update notification

I currently code an expiration date into my projects while i'm sending them out for review to prevent unfinished/out dated projects from existing. Is there a way to implement an "Updated version available" notification. Is there a service/asset anyone has used that they can recommend? Thanks.

 

I just throw up a text file on my server with the version string in it, and then fetch on startup like so:

Code (CSharp):

1.         WWW www = new WWW("http://highfrontier.com/version.txt");
2.         yield return www;
3.         Debug.Log("Version.txt contains: " + www.text);
4.         CheckVersion(www.text);
5.  

That is inside IEnumerator Startup(). Then the CheckVersion method compares the text found to a version constant baked into the app, and if it's newer, squawks at the user.

Simple, but effective I think.

 

Very nice, Ill try that out first thing. Seems like i could also disable a model for non payment. Thank you!
