Android CCLayer setTouchPriority无效
我创建了一个层,它的唯一目的是阻止(“吞咽”)接触,这个功能可以打开和关闭。 这门课非常基础,如果它受到触碰,它总是会吞下它:Android CCLayer setTouchPriority无效,android,ios,touch,cocos2d-x,cclayer,Android,Ios,Touch,Cocos2d X,Cclayer,我创建了一个层,它的唯一目的是阻止(“吞咽”)接触,这个功能可以打开和关闭。 这门课非常基础,如果它受到触碰,它总是会吞下它: bool BlockingLayer::init(){ // Super init. if ( !CCLayer::init() ) { return false; } setTouchEnabled(true); setTouchMode(kCCTouchesOneByOne); setTou
bool BlockingLayer::init(){
// Super init.
if ( !CCLayer::init() )
{
return false;
}
setTouchEnabled(true);
setTouchMode(kCCTouchesOneByOne);
setTouchPriority(INT_MAX);
return true;
}
bool BlockingLayer::ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent)
{
CCLOG("BlockingLayer swallowed touch!");
return true;
}
因此,默认情况下,它的优先级非常差,如果没有其他类声明它,它将接收触摸。但在我使用该层的场景中,当某些事件发生时,我希望将其设置为不同的优先级:
bool MyScene::init(int unitNumber, CCString* path){
// Super init.
...
_blockingLayer = BlockingLayer::create();
this->addChild(_blockingLayer);
return true;
}
bool MyScene::ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent){
_blockingLayer->setTouchPriority(INT_MIN);
...
}
现在图层应该有可能的最佳优先级,所以它应该吞下所有接触。但是它没有,它的行为没有改变。
我看到它的registerWithTouchDispatcher()被调用,并且m_ntouch优先级已正确更改。但该层的行为没有改变
这在Cocos2D-x2.2上。非常感谢您的帮助。在addTargetedElegate()中,将第三个参数设置为true
bool BlockingLayer::init(){
// Super init.
if ( !CCLayer::init() )
{
return false;
}
setTouchEnabled(true);
setTouchMode(kCCTouchesOneByOne);
setTouchPriority(INT_MAX);
return true;
}
void BlockingLayer::onEnter()
{
CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(this, INT_MAX, true); //<---- Param (target, touchPriority, isSwallowTouches )
CCNode::onEnter();
}
void BlockingLayer::onExit()
{
CCDirector::sharedDirector()->getTouchDispatcher()->removeDelegate( this );
CCNode::onExit();
}
bool BlockingLayer::ccTouchBegan(CCTouch *pTouch, CCEvent *pEvent)
{
CCLOG("BlockingLayer swallowed touch!");
return true;
}
bool BlockingLayer::init(){
//超级初始化。
如果(!CCLayer::init())
{
返回false;
}
setTouchEnabled(真);
设置触摸模式(kCCTouchesOneByOne);
setTouchPriority(INT_MAX);
返回true;
}
void BlockingLayer::onEnter()
{
CCDirector::sharedDirector()->getTouchDispatcher()->AddTargetedElegate(this,INT_MAX,true);//getTouchDispatcher()->RemoveDeleteGate(this);
CCNode::onExit();
}
bool BlockingLayer::CCTouch开始(CCTouch*pTouch,CCEvent*pEvent)
{
CCLOG(“BlockingLayer吞下触摸!”);
返回true;
}
原来这是Cocos2d-x中的一个bug:
见此:
解决方案:
CCTouchDispatcher.cpp中的更改
这:

为此:
void CCTouchDispatcher::addStandardDelegate(CCTouchDelegate *pDelegate, int nPriority)
{
CCTouchHandler *pHandler = CCStandardTouchHandler::handlerWithDelegate(pDelegate, nPriority);
if (! m_bLocked)
{
forceAddHandler(pHandler, m_pStandardHandlers);
}
else
{
/* If pHandler is contained in m_pHandlersToRemove, if so remove it from m_pHandlersToRemove and return.
* Refer issue #752(cocos2d-x)
*/
if (ccCArrayContainsValue(m_pHandlersToRemove, pDelegate))
{
CCTouchHandler *pOldHandler = findHandler(pDelegate);
if (pOldHandler && pOldHandler->getPriority() == nPriority)
{
ccCArrayRemoveValue(m_pHandlersToRemove, pDelegate);
return;
}
}
m_pHandlersToAdd->addObject(pHandler);
m_bToAdd = true;
}
}

我发现这个错误修复导致了这个新的错误:最后一条评论正好显示了这个问题。如果你在任何层上添加
TargetDelegate
,那么你必须删除它才能正常工作。您可以在onExit()
中删除,也可以在需要的任何位置手动调用。所有这些都会在启用触摸的CCLayers上自动发生。将自动调用他们的registerWithTouchDispatcher方法,该方法调用所提到的行。:)但我在非CCLayer类中使用您的方法。:)
