Hi, i am replacing an scene with a transition.
I need to know which is the current scene after the transition, so in onEnterTransitionDidFinish i do
CCScene * current = [[CCDirector sharedDirector] runningScene];
But instead of returning the new scene, it returns a CCFadeTransition instance, which i guess is not the correct behaviour.
Don't know about the BUG, but curious why you need [[CCDirector sharedDirector] runningScene] at all? If you're already in that scene's "onEnterTransitionDidFinish" method, then your current scene is "self"
I am using openfeint, and for using a custom approval screen i have to use a delegate function (my delegate being the game's appDelegate) so in that method i need to retrieve the current scene to add a layer to whichever scene is running at the time.
At least it is the only way i found to do that.
it's not a bug.
The current scene, when you are transitioning from one scene to another one, is a transition scene.
If you look at the CCTranstion.h, you'll notice that CCTransition is a subclass of CCScene
But if i am trying to get it onEnterTransitionDidFinish, where supposedly the transition did finish, shouldn't i be getting the new scene instead of the transition?
I'm not sure what you are trying to do with currentScene, but you should use it with care.
The onEnterTransitionDidFinish message is triggered when the transition finishes (the visual transition). It doesn't guaranty you that the Transition Scene was removed from memory... in fact that can't happen since the object that triggers the onEnterTransitionDidFinish is the Transition Scene.
ok.
The thing is, openfeint message could be triggered anytime, i mean i could be in any scene when i receive a notification from openfeint. My delegate for that is the game's appDelegate so when the openfeint approval screen is triggered i am supposed to intercept that and show a Cocos2d layer (instead of the original openfeint screen).
So the only way i figured i could do that is find what is the scene that i am in, retrieve it and add a layer to it on top, whichever the scene is.
So, what you should do is:
- if current scene is not a Transition, then use it as the delegate.
- if current scene is a Transition, then use Transtion.inScene as the delegate.
probably inScene is not a property, so you'll need to make it a property.
If that works, and you want that patch to be part of cocos2d, please open a ticket. thanks.
Ok, i will look into that.
Right now what i did to solve the issue is onEnterTransitionDidFinish, schedule my method to run after 0.5 seconds instead of instantly, now it does work fine. Although i don't know if there would be any scenario where this could break.
