Hello, guys!
I met a problem.
I made a Consequence Action of which the last action is a subclass of FadeOut. and i overrided stop function of it. But, when I checked which function is called between Action's stop, and the overriden stop, the answer was Action's stop!
I have no idea. I overrode start function right above the stop function, and it worked just fine! Only stop doesn't work.
What is wrong with this? Do you have any idea?! Help me!

What method did you use to instantiate the object? Can we see some code? I ran into this once, and my problem was using a factory methods from the wrong class. Not sure if this is what is happening in your case but I can't think of any other reason.
What I mean is that if you instantiated it using a factory method and didn't reference your subclass in doing so, you won't actually get a copy of the subclass's object, and none of your overriden methods will be used.

Here is the entire code.
@interface OpeningLastAction : FadeOut
{
}
-(void) stop;
@end
@implementation OpeningLastAction
-(void) stop
{
Layer *layer = [MenuLayer node];
[[Director sharedDirector] replaceScene:[[Scene node] addChild:layer]];
}
@end
@implementation OpeningLayer
-(id)init
{
if(self = [super init])
{
Sprite *jkEntertainment = [Sprite spriteWithFile:@"jk entertainment.png"];
CGSize size = [[Director sharedDirector] winSize];
[jkEntertainment setPosition: ccp(size.width/2, size.height/2)];
ScaleTo *stay = [ScaleTo actionWithDuration: 2 scale:1.0];
OpeningLastAction *fadeOut = [OpeningLastAction actionWithDuration:1];
Sequence *action = [Sequence actions: stay, fadeOut, nil];
[jkEntertainment runAction:action];
[self addChild:jkEntertainment];
}
return self;
}
@end

Does factory class means parent class? I don't know. When I overrode start function, the overriden was called. And the stop function that is overriden right below the start function is not called but Action's stop function. Have no idea how can this happen. But you guys know better than me so I hope you guys can find the solution.

I see two problems.
1. Don't declare "stop" in your interface. You're inheriting it from your parent and this re-declaration is unnecessary and may be problematic.
2. You aren't telling the parent stop function to run. You need add "[super stop];" to your override function.
I would add that if this is all you want to do, a subclass of the FadeOut action may not be the best way to do it. You have two action that take a total of 3 seconds to run, so you can just schedule a selector with a 3 second interval and put your replaceScene call in there. As in:
[self schedule:@selector(onComplete:) interval:3];
And your onComplete function would look like this:
- (void) onComplete:(ccTime) dt
{
[self unschedule:@selector(onComplete:)];
Layer *layer = [MenuLayer node];
[[Director sharedDirector] replaceScene:[[Scene node] addChild:layer]];
}
Same effect, but no need to create a subclass!

Thanks for fast reply, but none of them solved my problem Q.Q, except for the last case. I wanted to use the subclass method because the fact that after all the actions are done, you go to the main menu made much more sense. But since it doesn't work for me, I think I should use what you suggested! And I guess,,, is it more efficient because you don't need to make a subclass..?
Num1: shouldn't be a problem because I have been doing it in all the other files and it was fine, and in theory shouldn't be a problem. But not doing it makes much more sense, so I deleted it. Thank you!
Num2: Action's stop function is totally empty except for one comment: // Please override me.(lol)
So I'm kind of thinking it shouldn't be a problem. And this stop function is not for stopping action, but the function that's called when an action is done. I think That's why it is empty except for one comment; it was from the first designed to be overriden. Moreover, as I said, when start was overriden, which is exactly the same to the stop function, it worked, but the stop function doesn't work. Weird!!!!!!!!!

No..that's really weird thing. I put NSLog in both stop and start in both subclass and Action, and in the case of start, overriden one was called, and the case of stop, Action's one was called. Isn't it really weird?! Does it happen to you too? I started to wonder if it's just my problem or to all
