hi guys, i want use the way:[[CCTouchDispatcher sharedDispatcher] targetedHandlers]
so how can i use similar way in cocos2d-x, cause in cocos2d-x,
“protected:
CCMutableArray<CCTouchHandler*> *m_pTargetedHandlers;
CCMutableArray<CCTouchHandler>**m_pStandardHandlers;
”
it’s protected, so what can i get m_pTargetedHandlers using the CCTouchDispatcher::sharedDispatcher()?
please help me! cause i am using CCScrollLayer.h & CCScrollLayer.m, but i am developing using cocos2d-x,
so i must change CCScrollLayer.h&.m to CCScrollLayer.h &.cpp,
but CCScrollLayer.m have used the
"
- (void) claimTouch: (UITouch *) aTouch
{
// Enumerate through all targeted handlers.
for ( CCTargetedTouchHandler *handler in [[CCTouchDispatcher sharedDispatcher] targetedHandlers] )
{
// Only our handler should claim the touch.
if (handler.delegate self)
{
if (![handler.claimedTouches containsObject: aTouch])
{
[handler.claimedTouches addObject: aTouch];
}
else
{
//CCLOGERROR(@“CCScrollLayer#claimTouch: %@ is already claimed!”, touch);
}
return;
}
}
}
"
it’s CCScrollLayer.h

/*
It is a very clean and elegant subclass of CCLayer that lets you pass-in an array
of layers and it will then create a smooth scroller.
Complete with the “snapping” effect. You can create screens with anything that can be added to a CCLayer.
Additions since Giv Parvaneh version:
1. Added ability to swipe above targetedTouchDelegates.
2. Added touches lengths & screens properties.
3. Added factory class method.
4. Code cleanup.
5. Added current page number indicator (iOS Style Dots).
Limitations:
1. Mac OS X not supported.
2. Standard Touch Delegates will still receive touch events after layer starts sliding.
