本文主要是介绍CCLayer注册lua回调函数setTouchPriority失效，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
CCLayer注册lua回调函数setTouchPriority失效：方式1、不行touchLayer:setTouchPriority(-5000) touchLayer:registerScriptTouchHandler(touchLayerCallFunc)touchLayer:setTouchEnabled(true)maskLayer:addChild(touchLayer)方式2、可以
touchLayer:registerScriptTouchHandler(touchLayerCallFunc, false, -5000, true)
touchLayer:setTouchEnabled(true)
maskLayer:addChild(touchLayer)原因：void CCLayer::registerWithTouchDispatcher()
{CCTouchDispatcher* pDispatcher = CCDirector::sharedDirector()->getTouchDispatcher();// Using LuaBindings/*我们使用registerScriptTouchHandler方法注册了回调，所以m_pScriptTouchHandlerEntry不为空：void CCLayer::registerScriptTouchHandler(int nHandler, bool bIsMultiTouches, int nPriority, bool bSwallowsTouches){unregisterScriptTouchHandler();m_pScriptTouchHandlerEntry = CCTouchScriptHandlerEntry::create(nHandler, bIsMultiTouches, nPriority, bSwallowsTouches);m_pScriptTouchHandlerEntry->retain();}*/if (m_pScriptTouchHandlerEntry){if (m_pScriptTouchHandlerEntry->isMultiTouches()) //多点触摸{pDispatcher->addStandardDelegate(this, 0);LUALOG("[LUA] Add multi-touches event handler: %d", m_pScriptTouchHandlerEntry->getHandler());}else //单点触摸{//注意这里和C++的不同，这个的优先级和是否吞噬，都是CCTouchScriptHandlerEntry类中的成员变量，//也就是我们调用registerScriptTouchHandler方法传进来的值，而不是通过setTouchPriority方法设置//的m_nTouchPriority成员变量，这个变量对于lua没用。pDispatcher->addTargetedDelegate(this,m_pScriptTouchHandlerEntry->getPriority(),m_pScriptTouchHandlerEntry->getSwallowsTouches());LUALOG("[LUA] Add touch event handler: %d", m_pScriptTouchHandlerEntry->getHandler());}}else{if( m_eTouchMode == kCCTouchesAllAtOnce ) {pDispatcher->addStandardDelegate(this, 0);} else {//C++中调用优先级才会用到m_nTouchPriority变量，即可以通过setTouchPriority方法设置。pDispatcher->addTargetedDelegate(this, m_nTouchPriority, true);}}
