Get all children from the Node

cocos2d-x C++
#1

Hello.
as the tittle says, i am looking for a pause feature, so that i can get all child in the nodes to be paused.

I think you want to use the Node::doEnumerateRecursive function

In cocos2dx-2.x I had a recursive function like this that did the trick:-

void Game::pauseNodeAndDescendants(CCNode* pNode)

{
pNode->pauseSchedulerAndActions();
CCObject* pObj = nullptr;
CCARRAY_FOREACH(pNode->getChildren(), pObj)
pauseNodeAndDescendants((CCNode*)pObj);
}

not sure why, i keep getting this error on the V3
error C2039: ‘data’ : is not a member of ‘cocos2d::Node’

#5

What code does the error point to?

#7

the CCARRAY_FOREACH

how do i actually call this function…
i called it like this pauseNodeAndDescendants(this);

You’re probably using V3 of cocos2dx and @IslandPlaya’s code is for V2. The main difference here is that V3 uses Vectors instead of CCArrays. CCArrays have a member called ‘data’, where as Vectors do not. If you want to convert his V2 code to V3, it would look something like this:

void Game::pauseNodeAndDescendants(Node *pNode)
{
    pNode->pauseSchedulerAndActions();
    for(const auto &child : pNode->getChildren())
    {
        this->pauseNodeAndDescendants(child);
    }
}

Thank you so much for this works now
Edit:-
have another proble now… cant resume… seems like even the event listener is paused

Yes, the pauseSchedulerAndActions() method looks like this in CCNode.cpp:

void Node::pause()
{
    _scheduler->pauseTarget(this);
    _actionManager->pauseTarget(this);
    _eventDispatcher->pauseEventListenersForTarget(this);
}

void Node::pauseSchedulerAndActions()
{
    pause();
}

So instead of calling Node::pauseSchedulerAndActions(), you could just pause the action manager, which is probably what you want, right?
