repalceScene remembering touch controls?

cocos2d-x C++
#1

Hi there,

I have a multi-scene project and I move between scenes using repalceScene.

When I move from one scene to another, it remembers my touch events. For example, if I click the Credits button from the main menu I can tap anywhere on the screen to return to the main menu. Now if I tap on a empty part of the screen on the menu scene it calls “Director::getInstance()->replaceScene(TransitionRotoZoom::create(1, scene));” again, reloading the MenuScene along with transition effect.

I can’t see why it’s doing this. Does anyone have any ideas?

I create the scene with:

    Scene* CreditsScene::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();
    
    // 'layer' is an autorelease object
    auto layer = CreditsScene::create();

    // add layer as a child to scene
    scene->addChild(layer);

    // return the scene
    return scene;
}

Create my touch like this:

//Touch listener
	auto touchListener = EventListenerTouchOneByOne::create();
	touchListener->onTouchBegan = CC_CALLBACK_2(CreditsScene::TouchBegan, this);
	getEventDispatcher()->addEventListenerWithFixedPriority(touchListener, 100);

And call replaceScene like this:

void CreditsScene::returnToMenu()
{
	//Returns to MenuScene
	auto scene = MenuScene::createScene();

	Director::getInstance()->replaceScene(TransitionRotoZoom::create(1, scene));
}

This also happens when I go from my GameScene back to my MenuScene, but that causes the app to crash.

I’d really appreciate it if someone could point me in the wrong direction!

Thanks :slight_smile:

I guess you need to remove event listener onExit()

As far as I know, only addEventListenerWithSceneGraph will be removed automatically.

Oh really? For some reason I thought everything was removed automatically.

I’m pretty new to this. Don’t suppose you’d have some example code? I’ve never done an onExit() or removed events before.

Thank you :slight_smile:

Does any have a good example on how to setup/handle onExit()?

Thanks!
