[C#]How to judge the passage of time
Set a playtime, e.g.
Time is 4 minutes, if the time decreases every 1 second, an event is triggered
Game.GameTime, This is measured in milliseconds.
From when you want to start counting store the time:
Int Time = Game.GameTime;
Then compare the current time to the stored time:
if(Game.GameTime > Time + 1000) Time = Game.GameTime; // 1 second has past.
