Cocos2d-x 3.2 大富翁游戏项目开发-第二十四部分 彩票开奖

每隔N个回合，彩票开奖一次，每期开奖奖金固定5万，暂不累积。摇奖效果一般，以后考虑用物理引擎实现

1、定义彩票开奖类

bool LotteryPublish::init(){addItemSpriteFrameCache();SpriteFrame* spf;spf = itemSpriteFrameCache->getSpriteFrameByName("publish_ly01.png");Sprite::initWithSpriteFrame(spf);setItemAnimate();return true;}void LotteryPublish::addItemSpriteFrameCache(){itemSpriteFrameCache = SpriteFrameCache::getInstance();itemSpriteFrameCache->addSpriteFramesWithFile("images/publish_ly.plist","images/publish_ly.png");memset(name, 0, 20);for (int i=1; i<=21; i++) {sprintf(name, "publish_ly%02d.png",i);item_anim_vector.pushBack(itemSpriteFrameCache->getSpriteFrameByName(name));}}//开奖动画void LotteryPublish::setItemAnimate(){if(!AnimationCache::getInstance()->getAnimation("publish_ly_animation")){AnimationCache::getInstance()->addAnimation(Animation::createWithSpriteFrames(item_anim_vector,0.1f),"publish_ly_animation");} normal_anmi = Animate::create(AnimationCache::getInstance()->getAnimation("publish_ly_animation")); normal_anmi->retain();}

2、创建开奖画面的对话框。

void GameBaseScene::initPopPublishLottery(){popDialogLottery = PopupLayer::create(DIALOG_BG);popDialogLottery->setContentSize(CCSizeMake(Dialog_Size_Width, Dialog_Size_Height+180)); popDialogLottery->setTitle(LanguageString::getInstance()->getLanguageString(PUBLISH_LOTTERY)->getCString());popDialogLottery->setContentText("", 20, 60, 250);popDialogLottery->setPopType(LOTTERY_PUBLISH);//开奖类型的对话框popDialogLottery->setPlayerVector(players_vector);//传入角色容器，开奖画面会根据这个显示角色购买的彩票号码popDialogLottery->setTag(100);this->addChild(popDialogLottery);popDialogLottery->setVisible(false);}在显示Go按钮之前，根据回合数显示开奖界面void GameBaseScene::receivedNotificationOMsg(Object* data){.............case MSG_GO_SHOW_TAG:{//便于测试，每一回合结束都显示开奖画面if(gameRoundCount !=0 && gameRoundCount%1 == 0){//前面角色买地等，会播放动画，所以这里延迟一下，显示开奖画面scheduleOnce(schedule_selector( GameBaseScene::popPublishLottery),2.0f);}else{showGoButton();}break;}............}//把开奖画面显示出来，并播放摇奖动画void GameBaseScene::popPublishLottery(float dt){popDialogLottery->setVisible(true);//开奖画面中添加角色购买的彩票号码popDialogLottery->addPlayersLottery();//播放摇奖动画popDialogLottery->runPublishAnmi();}

3、在PopupLayer.h中添加开奖对话框枚举LOTTERY_PUBLISH

enum POP_TYPE{NORMAL,LOTTERY,LOTTERY_PUBLISH,STOCK,};//当对话框进入后调用setPublishLotteryContext,在对话框中添加开奖画面void PopupLayer::onEnter(){......case LOTTERY_PUBLISH:{setPublishLotteryContext(contentSize);break;}.....}//在对话框中添加开奖画面void PopupLayer::setPublishLotteryContext(Size size){Size winSize = Director::getInstance()->getWinSize();lp = LotteryPublish::create();addChild(lp);lp->setPosition((winSize)/2);addPlayersInfo(size);}

//添加角色图标

void PopupLayer::addPlayersInfo(Size size){Size winSize = Director::getInstance()->getWinSize();Size center =(winSize-size)/2;int j=0;for(auto it=players_vector.begin();it!=players_vector.end();it++){RicherPlayer* player = dynamic_cast<RicherPlayer*>(*it);SpriteFrame* spf;int tag = player->getTag();switch(tag){case PLAYER_1_TAG:{spf = player->player_spriteFrameCache->getSpriteFrameByName("player1_anim_01.png");break;}case PLAYER_2_TAG:{spf = player->player_spriteFrameCache->getSpriteFrameByName("player2_anim_02.png");break;}}Sprite* playerSprite = Sprite::createWithSpriteFrame(spf);playerSprite->setPosition( center.width+20, (winSize.height/2+50)+j*50);addChild(playerSprite);j++;}}

//添加角色购买的彩票

void PopupLayer::addPlayersLottery(){for(int i=1;i<=30;i++){if(this->getChildByTag(1000+i) != NULL){this->removeChildByTag(1000+i);}}Size winSize = Director::getInstance()->getWinSize();Size size = this->getContentSize();Size center =(winSize-size)/2;int j=0;for(auto it=players_vector.begin();it!=players_vector.end();it++){RicherPlayer* player = dynamic_cast<RicherPlayer*>(*it);playerLotteryVector.clear();for(int i=0;i < player->lottery_vector.size();i++){LabelTTF* labelLotteryNumber = LabelTTF::create(String::createWithFormat("%i",player->lottery_vector.at(i))->getCString(),"",15);labelLotteryNumber->setPosition(ccp( center.width+20+(i+1)*20, (winSize.height/2+30)+j*50));labelLotteryNumber->setColor(Color3B(255,100,100));labelLotteryNumber->setTag(1000+player->lottery_vector.at(i));playerLotteryVector.pushBack(labelLotteryNumber);}for(int i=0;i < playerLotteryVector.size();i++){addChild(playerLotteryVector.at(i));}j++;}}

//开始摇奖动画

void PopupLayer::runPublishAnmi(){scheduleOnce(schedule_selector( PopupLayer::realRunPublishAnmi),3.0f);}

//开始真正摇奖

void PopupLayer::realRunPublishAnmi(float dt){lp->runAction(Sequence::create(lp->getNormal_anmi(),CallFunc::create([this](){int lott = rand()%(30)+1;//四秒后 让开奖画面消失scheduleOnce(schedule_selector( PopupLayer::dismissFromParent),4.0f);Sprite* ball = Sprite::create("images/orange_ball.png");ball->setPosition(lp->getPosition()-lp->getContentSize()/2 + ccp(0,13));ball->setAnchorPoint(ccp(0,0));addChild(ball);LabelTTF* ltf = LabelTTF::create(String::createWithFormat("%02d",lott)->getCString(), "", 20);ltf->setPosition(ball->getPosition()+ccp(5,6));ltf->setAnchorPoint(ccp(0,0));addChild(ltf);Size winSize = Director::getInstance()->getWinSize();Size center =(winSize)/2;int j=0;//判断角色是否中奖for(auto it=players_vector.begin();it!=players_vector.end();it++){RicherPlayer* player = dynamic_cast<RicherPlayer*>(*it);//player->lottery_vector.push_back(8);for(int i=0;i < player->lottery_vector.size();i++){if(player->lottery_vector.at(i) == lott){player->setMoney(player->getMoney()+LOTTERY_WIN_MONEY);ParticleSystem* lotteryWinParticle = ParticleSystemQuad::create("images/lottery_win.plist");lotteryWinParticle->retain();ParticleBatchNode *batch = ParticleBatchNode::createWithTexture(lotteryWinParticle->getTexture());batch->addChild(lotteryWinParticle);addChild(batch);lotteryWinParticle->setPosition( center.width+20, (winSize.height/2+50)+j*50 );lotteryWinParticle->release();lotteryWinParticle->setAutoRemoveOnFinish(true); }}player->lottery_vector.clear();j++;}}),NULL));}

//发送对话框消失消息，并设置为不可见

void PopupLayer::dismissFromParent(float dt){NotificationCenter::getInstance()->postNotification(MSG_DIMISS_DIALOG,String::createWithFormat("%d",MSG_DIMISS_DIALOG_PUBLISH_LOTTERY_TAG));this->setVisible(false);}

4、GameBaseScene收到该消息后，更新资金，并显示Go按钮

case MSG_DIMISS_DIALOG_PUBLISH_LOTTERY_TAG:{//this->removeChildByTag(100);for(auto it=players_vector.begin();it!=players_vector.end();it++){RicherPlayer* player = dynamic_cast<RicherPlayer*>(*it);refreshMoneyLabel(player,0);}showGoButton();break;}
