Question

I have a method that starts my game (startGame). I call it in viewDidLoad ([self startGame];). The problem is, that the start game method checks to see if an object has moved before it starts the game. The setup I have right now only calls the method once and doesn’t check it again which means my game never starts. Any ideas on how I can continue checking the method UNTIL the game starts, and then stop checking it?

Thanks. Happy 2012

there are a few things you can do.. one of the easiest would be to use a NSTimer. so in your viedDidLoad method you could do:

[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(checkObjectMoved:) userInfo:NULL repeats:YES]; // check every 1 second

then you’d have:

- (void)checkObjectMoved:(NSTimer *)timer {
  if object has NOT moved return;

  [timer invalidate];
  [self startGame];
}
