This is a tutorial I wrote recently about how to retrieve and show a Kongregate user’s avatar image in-game.
The post is at http://blog.dreasgrech.com/2013/04/showing-kongregate-users-avatar-image.html and I use a C# code example.
The end result is something like this:
In short, what I do is use the user-info REST API method to fetch details about the current user, extract the avatar url to download the image and then rendering it on screen as a texture.
If anyone should give it a look, I would really appreciate feedback on what I should add or correct in article. Cheers!
