Update: Sprite Vortex is now at 1.2.2 version with all major bugs fixed. I've made an example of how to parse the animations XML and created a ready to use Animation class that uses the parsed information. Currently the example uses Vortex2D engine, but XNA will follow. More info here: http://spritevortex.codeplex.com/
It would be great if someone find a way to use it in Construct
Obs.: I highly recommend Vortex2D engine for simple and professional 2D games with .NET. So if you are a C# programmer this engine is for you. I'm promoting it, yes , because i think it's great. Thank you all.
