Question

Is it possible to check if there are actions currently running in a CCNode class in Cocos2d? I’d like to know if a CCMoveBy is still running or not.

Answer 1

You can always add a method to indicate when the method is finished, and then toggle some BOOL or something like that to indicate it is not running, and put a start method to toggle the BOOL to indicate it started:

id actionMove = [CCMoveTo actionWithDuration:actualDuration 
 position:ccp(-target.contentSize.width/2, actualY)];

id actionMoveDone = [CCCallFuncN actionWithTarget:self 
selector:@selector(spriteMoveFinished:)];

id actionMoveStarted = [CCCallFuncN actionWithTarget:self 
selector:@selector(spriteMoveStarted:)];

[target runAction:[CCSequence actions:actionMoveStarted, actionMove, actionMoveDone, nil]];

Modified from here.

In the two @selector methods:

-(void) spriteMoveStarted:(id)sender {
    ccMoveByIsRunning = YES;
}

and:

-(void) spriteMoveFinished:(id)sender {
    ccMoveByIsRunning = NO;
}

where ccmoveByIsRunning is the BOOL I’m referring to.

EDIT: As xus has pointed out, you should actually not do this and instead use [self numberOfRunningActions] as others have pointed out.
