Cocos2d-x 3.2 大富翁游戏项目开发-第二十部分 螃蟹挡路(code)

概述该部分我们添加螃蟹伤人事件，道路位置随机添加螃蟹精灵，当角色行走完毕如果停留位置碰到了螃蟹，首先播放伤人动画，然后是播放救护车把角色带走动画。 如果轮流到该角色行走时，吐司提示住院还有几天，当住院天数到期，该角色才可以继续行走 新建了几个精灵类 Item_crab.cpp 螃蟹 Item_emergency.cpp 救护车 Item_fog.cpp 烟雾 Item_stretcher.cpp 担架 该部分我们添加螃蟹伤人事件，道路位置随机添加螃蟹精灵，当角色行走完毕如果停留位置碰到了螃蟹，首先播放伤人动画，然后是播放救护车把角色带走动画。
如果轮流到该角色行走时，吐司提示住院还有几天，当住院天数到期，该角色才可以继续行走

新建了几个精灵类

Item_crab.cpp 螃蟹
Item_emergency.cpp 救护车
Item_fog.cpp 烟雾

Item_stretcher.cpp 担架

//该方法在场景中添加这几个精灵voID GameBaseScene::initItemSprite(){	item_crab = (Item_crab*)Item::create(ITEM_CRAB);	addChild(item_crab);	item_crab->runAction(RepeatForever::create(item_crab->getnormal_anmi()));	item_crab->setVisible(false);	emerg = Item_emergency::create();    addChild(emerg);	emerg->setVisible(false);	fog = Item_fog::create();	addChild(fog);	fog->setVisible(false);	strentcher = Item_stretcher::create();	addChild(strentcher);	strentcher->setVisible(false);	strentcher->setAnchorPoint(ccp(0,0.9));}定义了定时器，每隔100秒调用该方法，更新螃蟹位置voID GameBaseScene::registerBlockWaySchedule(){	schedule(schedule_selector(GameBaseScene::updateBlockWaySprites),100.0f);}voID GameBaseScene::updateBlockWaySprites(float dt){	int _rand1 = rand()%(wayLayerPass_vector.size()); 	Vec2 position = wayLayerPass_vector.at(_rand1);	position.x -= 5;	position.y +=tiledHeight; 	item_crab->setVisible(true);	item_crab->setposition(position);	item_crab->setAnchorPoint(ccp(0,0.6));}

1、首先在RicherPlayer.cpp中，添加 restTimes 属性，记录受伤后，角色需要住院停留的回合数
2、修改voID RicherGameController::endGo()方法
当角色行走完毕，发送MSG_BLOCK_WAY_EVENT消息，该消息用来处理行走完毕后，检查道路上是否存在螃蟹等

voID RicherGameController::endGo(){	...........	if(stepHasGone >= stepsCount)	{		String * str = String::createWithFormat("%d-%f-%f-%d",MSG_BLOCK_WAY_EVENT_TAG,0.0f,_richerPlayer->getTag());		NotificationCenter::getInstance()->postNotification(MSG_BLOCK_WAY_EVENT,str);		return;	}	.............}

3、GameBaseScene.cpp注册MSG_BLOCK_WAY_EVENT消息观察者

voID GameBaseScene::registerNotificationObserver(){	...........		NotificationCenter::getInstance()->addobserver(		this,callfuncO_selector(GameBaseScene::receivednotificationOMsg),MSG_BLOCK_WAY_EVENT,NulL);	............}

4、receivednotificationOMsg 具体处理该消息，根据角色调用doblockWayEvent 方法

voID GameBaseScene::receivednotificationOMsg(Object* data){...........	case MSG_BLOCK_WAY_EVENT_TAG:		{			int playerTag = messageVector.at(3)->intValue();			switch(playerTag)			{				case PLAYER_1_TAG:				{					doblockWayEvent(player1);					break;				}				case PLAYER_2_TAG:				{					doblockWayEvent(player2);					break;				}							}						break;		}.............}

5、doblockWayEvent方法，就是根据角色判断是否碰到了螃蟹，如果碰到了，播放受伤等一系列动画，动画播放完毕后，设置角色不可见，并发送MSG_PICKONE_TOGO消息，让控制器取出下一个角色继续行走。

voID GameBaseScene::doblockWayEvent(RicherPlayer* player){	if(player->getBoundingBox().containsPoint(item_crab->getposition()+ccp(item_crab->getContentSize().wIDth/2,-item_crab->getContentSize().height/2)))	{			//碰到了螃蟹，设置螃蟹位置，让其不可见			item_crab->setposition(ccp(-200,-200));			//设置角色随机停留回合数			player->restTimes =  rand()%(5) + 1;;			log("doblockWayEvent intersetcRect");			//救护车变为可见			emerg->setVisible(true);			//救护车从右往左移动的距离			int distance = tableStartposition_x-player->getposition().x;			//救护车的位置			emerg->setposition(player->getposition()+ccp(distance,0));			//螃蟹和角色打架的烟雾动画			fog->setVisible(true);			fog->setposition(player->getposition());			Repeat* repeate0 = Repeat::create(fog->getnormal_anmi(),2);			fog->runAction(repeate0);			//救护车的移动动画			MoveBy* moveBy = MoveBy::create(1.0f,ccp(-distance,0));			MoveBy* moveBy2 = MoveBy::create(0.5f,ccp(-60,0));			Repeat* repeate = Repeat::create(emerg->getCar_go_anmi(),5);			Repeat* repeate2 = Repeat::create(emerg->getCar_stop_anmi(),1);			Sequence* spawnAction = Sequence::create(Spawn::create(moveBy,repeate,NulL),Spawn::create(moveBy2,repeate2,CallFunc::create(CC_CALLBACK_0(GameBaseScene::endCarGo,this)),NulL);			spawnAction->retain();			emerg->runAction(spawnAction);			//根据动画播放的时间设置角色不可见			if(player->getTag() == PLAYER_1_TAG)			{				scheduleOnce(schedule_selector(GameBaseScene::setPlayer1InVisible),2.5f);				}else if(player->getTag() == PLAYER_2_TAG)			{				scheduleOnce(schedule_selector(GameBaseScene::setPlayer2InVisible),2.5f);				}			//Toast显示角色受伤住院天数信息			CocosToast::createtoast(this,String::createWithFormat("%s %d %s",LanguageString::getInstance()->getLanguageString(PLAYER_HURT)->getCString(),player->restTimes,LanguageString::getInstance()->getLanguageString(RICH_DAY)->getCString())->getCString(),TOAST_SHOW_TIME,player->getposition());	}	else	{		//如果没有碰到螃蟹，角色继续发送消息用于处理停留位置事件：是否有问号时间，然后是上下左右相邻位置房屋是否需要购买升级缴纳过路费等		NotificationCenter::getInstance()->postNotification(MSG_HANDLE_PROP_EVENT,String::createWithFormat("%d",MSG_HANDLE_PROP_EVENT_TAG));	}}//让角色和打架烟雾动画不可见voID GameBaseScene::setPlayer1InVisible(float dt){	player1->setVisible(false);	fog->setVisible(false);}voID GameBaseScene::setPlayer2InVisible(float dt){	player2->setVisible(false);	fog->setVisible(false);}//救护车开来动画结束后调用该函数，播放小黄人抬担架动画voID GameBaseScene::endCarGo(){	strentcher->setVisible(true);	strentcher->setposition(emerg->getposition());	MoveBy* moveBy = MoveBy::create(0.5f,ccp(60,0));	ScaleBy* scaleBy = ScaleBy::create(0.5f,0.8);	Repeat* repeate = Repeat::create(strentcher->getStretcher_empty_anmi(),1);	ScaleBy* scaleBy2 = ScaleBy::create(0.5f,1.25);	MoveBy* moveBy2 = MoveBy::create(0.5f,0));	Repeat* repeate2 = Repeat::create(strentcher->getStretcher_full_anmi(),1);	Sequence* spawnAction = Sequence::create(Spawn::create(moveBy,scaleBy,scaleBy2,CallFunc::create(CC_CALLBACK_0(GameBaseScene::startCarGoAgain,NulL);	spawnAction->retain();	strentcher->runAction(spawnAction);}//小黄人抬担架动画播放完毕后，播放救护车开走动画voID GameBaseScene::startCarGoAgain(){	strentcher->setVisible(false);	int distance = emerg->getpositionX();	MoveBy* moveBy = MoveBy::create(1.0f,0));	Repeat* repeate = Repeat::create(emerg->getCar_go_anmi(),5);	Sequence* spawnAction = Sequence::create(Spawn::create(moveBy,CallFunc::create(CC_CALLBACK_0(GameBaseScene::endCarGolast,NulL);	spawnAction->retain();	emerg->runAction(spawnAction);}//救护车开走后，调用该方法，让救护车不可见，并发送MSG_PICKONE_TOGO消息，让其他角色继续行走voID GameBaseScene::endCarGolast(){	emerg->setVisible(false);	NotificationCenter::getInstance()->postNotification(MSG_PICKONE_TOGO,MSG_PICKONE_TOGO_TAG));}

6、查看控制器中pickOnePlayerToGo方法

voID RicherGameController::pickOnePlayerToGo(){	for(auto it=GameBaseScene::players_vector.begin();it!=GameBaseScene::players_vector.end();it++)		{			RicherPlayer* richerPlayer = dynamic_cast<RicherPlayer*>(*it);			//如果轮流到该角色行走，但是在受伤休息，则发送MSG_REST 休息消息			if(richerPlayer->getIsMyTurn() && richerPlayer->restTimes > 0 )			{				String * str = String::createWithFormat("%d-%f-%f-%d",MSG_REST_TAG,richerPlayer->getTag());				NotificationCenter::getInstance()->postNotification(MSG_REST,str);				return;			}			//如果轮流到角色行走，并且不在休息			if(richerPlayer->getIsMyTurn() && richerPlayer->restTimes == 0)			{				richerPlayer->setVisible(true);				//角色1 发送MSG_GO消息，显示go按钮				if(richerPlayer->getTag() == PLAYER_1_TAG )				{					NotificationCenter::getInstance()->postNotification(MSG_GO,MSG_GO_SHOW_TAG));					return;				}				//其他角色 获取路径，自动行走				int randNumber = rand()%6 + 1; 				RouteNavigation::getInstance()->getPath(richerPlayer,randNumber,GameBaseScene::canPassGrID,GameBaseScene::tiledRowsCount,GameBaseScene::tiledColsCount);				richerPlayer->startGo(RouteNavigation::getInstance()->getPathRow_vector(),RouteNavigation::getInstance()->getPathCols_vector());				return;			}		}	oneRoundDone = true;	//走到这里，说明角色都行走完毕，调用resetPlayerGoTurn方法，重新设置角色IsMyTurn为true等	resetPlayerGoTurn();	}//每一个回合结束后调用该方法，让角色的restTimes 减1 voID RicherGameController::resetPlayerGoTurn(){	for(auto it=GameBaseScene::players_vector.begin();it!=GameBaseScene::players_vector.end();it++)	{		RicherPlayer* richerPlayer = dynamic_cast<RicherPlayer*>(*it);		richerPlayer->setIsMyTurn(true);		richerPlayer->restTimes--;		if(richerPlayer->restTimes < 0)		{			richerPlayer->restTimes = 0;		}	}	//发送MSG_ROUND_COUNT 更新回合数	NotificationCenter::getInstance()->postNotification(MSG_ROUND_COUNT,MSG_ROUND_COUNT_TAG));	//设置完毕，继续调用pickOnePlayerToGo ，进行下一轮行走	pickOnePlayerToGo();}

7、GameBaseScene.cpp注册MSG_REST消息观察者

voID GameBaseScene::registerNotificationObserver(){...........		NotificationCenter::getInstance()->addobserver(		this,MSG_REST,NulL);.............}

8、处理MSG_REST消息
当收到休息的消息，首先设置IsMyTurn 为false，并吐司显示还需要休息几个回合，显示结束后调用GameBaseScene::sendMSGPickOnetoGO 方法，继续下一个角色行走

voID GameBaseScene::receivednotificationOMsg(Object* data){..........	case MSG_REST_TAG:		{			buy_land_x = messageVector.at(1)->floatValue();			buy_land_y = messageVector.at(2)->floatValue();			int playerTag = messageVector.at(3)->intValue();			switch(playerTag)			{				case PLAYER_1_TAG:				{					player1->setIsMyTurn(false);														CocosToast::createtoast(this,LanguageString::getInstance()->getLanguageString(IN_HOSPITAL_REMAIN)->getCString(),player1->restTimes,player1->getposition(),(SEL_CallFun)&GameBaseScene::sendMSGPickOnetoGO);									break;				}				case PLAYER_2_TAG:				{					player2->setIsMyTurn(false);					CocosToast::createtoast(this,player2->restTimes,player2->getposition(),(SEL_CallFun)&GameBaseScene::sendMSGPickOnetoGO);					break;				}							}						break;		}..........}

9、CocosToast.cpp 文件，添加了SEL_CallFun method 函数指针，用来调用传进来的方法，如 GameBaseScene::sendMSGPickOnetoGO 发送行走消息。
typedef voID (Layer::*SEL_CallFun)();
voID CocosToast::createtoast(cocos2d::Node *node,const std::string &msg,const float &time,Vec2 point,SEL_CallFun method)；

10、当角色行走完毕 停留位置的房屋所有者如果在住院，则免缴过路费。吐司提示，并调用GameBaseScene::sendMSGPickOnetoGO 发送行走消息

voID GameBaseScene::payTolls(int payTag,float x,float y,int playerTag){.............	if(landOwner->restTimes > 0)			{				CocosToast::createtoast(this,LanguageString::getInstance()->getLanguageString(IN_HOSPITAL)->getCString(),(SEL_CallFun)&GameBaseScene::sendMSGPickOnetoGO);				return;			}.............}
