Hi everybody,
I want to add sprites to my app with a different interval or delay time i.e. the sprties are added in random order.
Firstly I tried the following code but the interval is just randomized once at the first time.
[self schedule@selector:(addsprites) interval:(1+arc4random()%4)];
Then I tried to use Repeatforever but the delaytime doesn't work at all, sprites are added every frame.
Does anyone know how to achieve this?Thanks for your help.
In that method "addsprites" first unschedule the scheduler and then schedule it again with the same code...
@Dynex: The approach that @crmagicxxx posted in this thread last year is still the "proper way", as I see it. So the method itself is responsible for unscheduling itself, then adding itself to the schedule with the random interval after it has unscheduled itself. Seems pretty straightforward to me.

You can find some sample code here:

Related to the second thread I linked: the answer is no, there is no "more efficient" way to do it. Even if there was a built-in Cocos2d method for this, it would be doing the same thing behind the scenes.

Ah I see. Thanks for the quick replies. That method just seems so... odd. I don't think you can assume that a cocos2d method would be doing the same thing. Perhaps it would create an array of randoms and run through them.
Anyways, this will have to do :) As long as it doesn't slow my game down :P Thanks again guys.
The othe option is to have your scheduler decide if it needs to call another method or not randomly. That way it's all still going through one scheduler, you just have the option to do nothing or not. As long as your check isn't bloated it will keep things simpler. (don't know what the overhead is for scheduling and unscheduling over and over is, probably depends on how often you want it called...)
