   Hello, so basically what I was trying to accomplish was when a sprite got to a certain coordinate I wanted to put it at a certain location, pause for lets say 3 seconds, and then have its movement start again. I tried this:

   [self unschedule:@selector(move)];
           CCNode *ball = [self getChildByTag:kTagBall];
           ball.position = ccp(200, 200);
           float timeDelay = 3.0;
           id delay = [CCDelayTime actionWithDuration: timeDelay];
           id sequence = [CCSequence actions:delay, nil];
           [self runAction: sequence];
           [self schedule:@selector(move)];

   This is triggered when the sprite passes the certain spot, but no delay seems to happen! Thanks for your answers!

   id sequence = [CCSequence actions:delay, nil];

   There's nothing getting called after your delay. CCDelay doesn't delay any action from running on the node, only actions that come after it in a sequence.

   You may be able to schedule/unschedule using CCCallFuncO, however I've never tried. You might also come up with a completely different approach (though I like the idea of having control after each discrete move, instead of just running the move->pause sequence forever).

   id seq = [CCSequence actions: [CCDelayTime actionWithDuration: timeDelay], [CCCallFuncO actionWithTarget:self selector:@selector(schedule:) object:@selector(move)], nil ];

   Edit: (schedule) -> (schedule:)

   I might be doing it the long way, but I just use intermediate functions to handle delays:
   

   [self unschedule:@selector(move)];
   [self schedule: @selector(pauseMove) interval: 3];
   ...
   - (void) pauseMove
   {
   	[self schedule: @selector(move)];  // Profit
   }

   Oh, I guess I misunderstood how it worked. I just assumed it made a delay, regardless of whether or not their was another item in the sequence. When I use this code I get a "EXC_BAD_ACCESS" error, but thats because of poor memory management right? sorry newb :)

   I don't know if it's the preferred way, but it's simple and clean enough for me.
