how do i create a delay between tap gestures in XNA on wp7

Question

i am developing a mobile game using XNA and have an on and off switch which changes the state whenever tapped on. My problem is that it changes rapidly and multiple times from a single tap. How do i stop this?

Answer 1

Store a time the in-game switch was last used and calculate the timespan passed

if(buttonPressed && (Datetime.Now - timeLastInGameSwitchActivated).Milliseconds > 1000)
{
    ToggleIngameSwitch();
    timeLastInGameSwitchActivated = Datetime.Now;
}
