Toast
Android的Toast是一个View视图，快速为用户显示少量的信息。主要用于一些提示和帮助。本文实现了Toast最基本的操作能。
代码
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.cpp
#include "PigSprite.h"
#include "PlaneLayer.h"PigSprite::PigSprite() {
}PigSprite::~PigSprite() {
}bool PigSprite::init() {if (!Sprite::init()) {return false;}Size winSize = Director::getInstance()->getWinSize();spritepig = Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("hero_01.png"));this->setPosition(Point(winSize.width / 2, winSize.height / 2));this->addChild(spritepig);//设置缩放倍数为0.6，也就是变为原来的0.6this->setScale(0.6);//穿件小猪飞行动画f_createAnimate(3, 8);//时间调度函数，使每一帧都调用f_followPlane函数来保持小猪在飞机周围this->schedule(schedule_selector(PigSprite::f_followPlane));return true;
}
/*** 获取飞机的位置信息，使小猪的位置始终在飞机周围，函数中判断是否到达边界，以更新小猪* 在飞机的左边还是右边*/
void PigSprite::f_followPlane(float dt) {Size winSize = Director::getInstance()->getWinSize();auto PlanePos = PlaneLayer::sharedPlane->getChildByTag(AIRPLANE)->getPosition();if (PlanePos.x + 60 + spritepig->getContentSize().width <= winSize.width) {this->setPosition(Point(PlanePos.x + 60 + spritepig->getContentSize().width / 2,PlanePos.y));} else {this->setPosition(Point(PlanePos.x - 60 - spritepig->getContentSize().width / 2,PlanePos.y));}}
/*** 创建小猪飞行的动画，count为帧动画的数量，fps为每帧的间隔时间，* RepeatForever创建无限重复动画，让spritepig来执行这个动画*/
void PigSprite::f_createAnimate(int count, int fps) {char buff[16];Animation *panimation = Animation::create();panimation->setDelayPerUnit(1.0 / fps);for (int id = 1; id <= count; id++) {sprintf(buff, "hero_0%d.png", id);panimation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(buff));}spritepig->runAction(RepeatForever::create(Animate::create(panimation)));}使用代码：
