Cocos2d-x实现Android的Toast功能

//PacToast.h #include "cocos2d.h" #include "cocos-ext.h" #include "ui/CocosGUI.h" USING_NS_CC; USING_NS_CC_EXT; using namespace ui; class PacToast : public LayerColor { public: static void makeText(Node* node,const std::string& msg,const float& time);//静态函数，方便类直接调用 void removeToast(Node* node); };

//PacToast #include "PacToast.h" void PacToast::makeText(cocos2d::Node *node, const std::string &msg, const float &time) { Size visibleSize = Director::getInstance()->getVisibleSize(); Vec2 origin = Director::getInstance()->getVisibleOrigin(); auto pLabel = Label::createWithSystemFont(msg.c_str(), "Arial", 30); pLabel->setColor(Color3B::WHITE); pLabel->ignoreAnchorPointForPosition(false); pLabel->setAnchorPoint(Vec2::ANCHOR_MIDDLE); auto ly = LayerColor::create(Color4B(130,120,120,255)); ly->ignoreAnchorPointForPosition(false); ly->setAnchorPoint(Vec2::ANCHOR_MIDDLE); ly->setContentSize(pLabel->getContentSize() + Size(20,15)); node->addChild(ly); node->addChild(pLabel); ly->setPosition(Vec2(visibleSize.width/2,-pLabel->getContentSize().height)); pLabel->setPosition(ly->getPosition()); auto seq1 = Sequence::create(FadeIn::create(time/5), DelayTime::create(time/5*1.5),FadeOut::create(time/5*2.5),CallFuncN::create(ly,callfuncN_selector(PacToast::removeToast)),nullptr); auto seq2 = Sequence::create(EaseSineIn::create(MoveBy::create(time/5, Vec2(0,200))),DelayTime::create(time/5*2),EaseSineOut::create(MoveBy::create(time/3, Vec2(0,⑵00))), nullptr); auto spawn = Spawn::create(seq1, seq2, nullptr); auto action = Repeat::create(spawn,1); ly->setOpacity(0); pLabel->setOpacity(0); ly->runAction(action); pLabel->runAction(action->clone()); } void PacToast::removeToast(Node* node) { log("node = %s",node->getDescription().c_str()); this->removeFromParentAndCleanup(true); }
