WP7上的XNA读取触摸状态的频率是多少？

Question

How often does XNA on WP7 read touches state? Can I make XNA do it more often?

Answer 1

XNA's Update() method (one of the default five) is called 60 times a second, so the touch state can be updated in there thus meaning it is also updated 60 times a sec. Its your choice how you update the touch state. The win phone os will have internal updates but for your game you can check the states through the TouchPanel class.
