Hi,
I want to do some actions when player is holding a finger on the screen for more than 1 sec. The different touch callbacks doesn´t receive the time elapsed for last frame to let me check if finger was holded more than 1 seccond. I have been checking the docs and it seems there's no way to get it, the only thing we can do is setup a scheduled callback an wait, but this does not suit my needs.
Any suggestions?.
Thanks in advance,
HexDump.
I just actually had the same issue that I needed a work around..
I had a menu that I wanted to popup if you hold your finger in one spot for greater than 1 second, so what I did when I detect the initial touch I schedule a timer, and if anything happens (eg they move their finger, lift it whatever..) before the timer fires I unschedule the timer.
Works like a champ.
Essentially the same idea of a timer, not sure if it is any easier or cleaner, but delayed performSelector: comes up as a suggestion in Apple's touch documentation as a way to have a double tap action cancel an initial single tap, or a triple tap cancel a possible initiated double tap action...
So you could, in your
- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
make a call like
[self performSelector :@selector(doMyOneSecondAction)
withObject :nil
afterDelay :1.0];and in your methods
- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
- (void)ccTouchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
call
[NSObject cancelPreviousPerformRequestsWithTarget:self
selector :@selector(doMyOneSecondAction)
object :nil];You must log in to post.
