Question

I’m just trying to schedule an update method once in ccTouchesMoved, but when I add this

if (isRotating == YES)
        {
            gTimer = 20;
            [self schedule:@selector(g:) interval:1];
        }

in to ccTouchesMove it calls it every time the touch is moved. Is there a way to keep it in ccTouchesMoved and have it called just once?

isRotating is set to YES in ccTouchesMoved.

Code:

- (void)g:(ccTime)delta
{
    gTimer--;

    if (gTimer == 0 && isRotating == YES)
    {
        [self unschedule:@selector(g:)];
    }
}

All I want to do is rotate a sprite for a fixed interval then remove it when the timer is 0, but I only want to remove it if the touch is currently rotating the sprite.

Here is where pausing/resuming the timer comes in. If the player starts rotating the sprite then lifts their finger, the timer should pause and when they touch/rotate the sprite again the timer should resume.

If my explaining isn’t clear please feel free to ask me to elaborate.

Timer methods:

In .h

ccTimer gTimer;

In .m

- (void)g:(ccTime)delta
{
    gTimer--;

    if (gTimer == 0 && isRotating == YES)
    {
        [self unschedule:@selector(g:)];
    }
}

Also, I set the timer with

if (isRotating == YES)
        {
            gTimer = 20;
            [self schedule:@selector(g:) interval:1];
        }

Any help is greatly appreciated!

Answer 1

To pause the timer I just used

[self unschedule:@selector(g:)];

then to resume it I used

[self schedule:@selector(g:)];

Also, for scheduling update in ccTouchesMoved I just checked to see if the finger and stopped moving without being lifted.
