cocos2dx 按钮长按事件

通过touchBegin 结合 schedule 来实现

void UILayer::longTouchUpdate(float delay){

m_isLongPress = true;

if (m_longTouchButton != NULL){

if (m_longTouchButton->getName() == “jump_Btn”){

m_hero->floating();

}

}

}

// 长按事件的update 计时器

if (type == Widget::TouchEventType::BEGAN && m_hero != NULL)

{

schedule(schedule_selector(UILayer::longTouchUpdate), 0.5f);

else if (node->getName() == “jump_Btn”)

{

m_hero->jump();

m_longTouchButton = node;

}

}

在事件begin中开启 schedule ， 并且获得长按按钮的引用。

if (type == Widget::TouchEventType::ENDED && m_hero != NULL){

unschedule(schedule_selector(UILayer::longTouchUpdate));

if (m_isLongPress == true)

{

if (m_longTouchButton->getName() == “jump_Btn”)

{

m_hero->finishFloating();

}

m_longTouchButton = NULL;

m_isLongPress = false;

}

// 按钮抬起时将长按按钮清空
