如何在Cocos2d中添加不受场景转换影响的全局CCLayer? [英] How to add global CCLayer which is not affected by scene transitions in Cocos2d?

问题描述

是否可以在不受场景转换影响的Cocos2d中添加全局图层?

Is it possible to add global layer in Cocos2d, which is not affected by scene transitions?

如我所见，它应该位于所有场景层次之上.

As I can see, it should be above all scenes hierarchy.

在Cocos2d论坛上有一个简短的讨论，但没有答案: http://www.cocos2d-iphone.org/forum/topic/8071

There's an old and short discussion on Cocos2d forum, but there's no answer: http://www.cocos2d-iphone.org/forum/topic/8071

UPD.通过场景过渡"是指通过动画场景过渡".

UPD. 'by scene transitions' I mean 'by animated scene transitions'.

推荐答案

您可以使用CCDirector的notificationNode属性来放置CCNode(即CCLayer，CCLabel等)，该CCNode即使在过渡期间也将保留在场景上方.像这样:

You can use the notificationNode property of CCDirector to place a CCNode (ie.CCLayer, CCLabel, etc.) that will remain above scenes, even during transitions. Something like this:

CCLayer *layer = [CCLayer node];
CCLabelTTF *label = [CCLabelTTF labelWithString:@"Test" fontName:@"Marker Felt" fontSize:32];
[layer addChild:label];
[[CCDirector sharedDirector] setNotificationNode:layer]; // Layer should be placed here
[layer onEnter]; // Schedule for updates (ie. so that CCActions will work)

这是出于通知目的(广告等)，因此我不建议您尝试从该节点上做任何花哨的事情.

It's meant for notification purposes (ads, etc.) so I wouldn't suggest trying to do anything too fancy from this node.
