问题
I use XNA to develop small 2D games. The user should have the ability to interact with the game by using the mutli touch gestures in Windows 7. I want the same multi touch functionality in XNA as WPF provides. Are there any frameworks or built-in features?
回答1:
As you probably already know, the XNA touch API does not work on Windows, only on Windows Phone.
This blog post explains why and also lists some methods for getting touch input working.
回答2:
Try reading this code sample about touch-based textures for WP7, it can be useful for what you want.
