Cocos2d-x 3.2 大富翁游戏项目开发-第十八部分 问号随机事件
角色走完要求的步数后,先查看停留位置是否有问号,如果有,先处理问号事件,处理完毕后,再处理相邻周边上下左右地块问题,购买、升级或缴纳过路费。
问号随机事件主要是如下事件:
政府鼓励投资,返还税金10000
政府严查账务,补交税金20000
喝到假酒,上吐下泻,体力耗光
吃了大补丸,体力恢复
投资获利,分红20000
投资失败,亏损30000
由于还没有进行国际化处理,在用中文的时候,会出现乱码,我们暂时先都用英文处理一下,后期统一做国际化处理
1、与之对应的变量定义在ConstUtil.h文件中:
const int TAX_REBATES_TAG = 1; //政府鼓励投资,返还税金10000 const int PAY_TAXES_TAG = 2; //政府严查账务,补交税金20000 const int LOSS_STRENGTH_TAG =3;//喝到假酒,上吐下泻,体力耗光 const int PHYSICAL_RECOVERY_TAG =4;//吃了大补丸,体力恢复 const int INVESTMENT_DIVIDENDS_TAG = 5 ;//投资获利,分红20000 const int INVESTMENT_LOSS_TAG = 6; //投资失败,亏损30000 #define TAX_REBATES "The government encourages investment, tax rebates 10000" #define PAY_TAXES "Government scrutiny of accounts, pay taxes 20000" #define LOSS_STRENGTH "To drink alcohol, diarrhea, loss of light strength" #define PHYSICAL_RECOVERY "Eat cake, physical recovery" #define INVESTMENT_DIVIDENDS "Investment profits, dividends 20000" #define INVESTMENT_LOSS "Investment failure, loss 30000"
2、在GameBaseScene.cpp初始化随机事件Map容器
void GameBaseScene::initRandomAskEvent() { randomAskEventMap.insert(TAX_REBATES_TAG,__String::create(TAX_REBATES)); randomAskEventMap.insert(PAY_TAXES_TAG,__String::create(PAY_TAXES)); randomAskEventMap.insert(LOSS_STRENGTH_TAG,__String::create(LOSS_STRENGTH)); randomAskEventMap.insert(PHYSICAL_RECOVERY_TAG,__String::create(PHYSICAL_RECOVERY)); randomAskEventMap.insert(INVESTMENT_DIVIDENDS_TAG,__String::create(INVESTMENT_DIVIDENDS)); randomAskEventMap.insert(INVESTMENT_LOSS_TAG,__String::create(INVESTMENT_LOSS)); }
3、当角色走完步数后,会调用到RicherGameController的handlePropEvent方法。
在该方法中我们判断角色停留的位置是否有问号,如果有,就发送一个问号信息MSG_RANDOM_ASK_EVENT,同时方法返回。如果没有问号,就调用aroundLandEvent()方法,这个方法是处理角色周边相邻上下左右地块信息的方法,我们把以前的代码抽取成了该方法,便于后期重复使用
void RicherGameController::handlePropEvent() { oneRoundDone =false; float playerEnd_X = _colVector[stepsCount]*32; float playerEnd_Y = _rowVector[stepsCount]*32 + 32; Point pointInMap = Util::GL2map(Vec2(playerEnd_X,playerEnd_Y), GameBaseScene::_map); int endId = GameBaseScene::wayLayer->getTileGIDAt(pointInMap); if(endId == GameBaseScene::randomEvent_tiledID) { String * str = String::createWithFormat("%d-%f-%f-%d",MSG_RANDOM_ASK_EVENT_TAG,pointInMap.x,pointInMap.y,_richerPlayer->getTag()); NotificationCenter::getInstance()->postNotification(MSG_RANDOM_ASK_EVENT,str); return; } aroundLandEvent(); }
4、GameBaseScene.cpp中注册了对问号信息MSG_RANDOM_ASK_EVENT的处理
void GameBaseScene::registerNotificationObserver() { ……………………….. NotificationCenter::getInstance()->addObserver( this, callfuncO_selector(GameBaseScene::receivedNotificationOMsg), MSG_RANDOM_ASK_EVENT, NULL); ……………………. }
处理方法在receivedNotificationOMsg()方法中,当接收到问号信息,根据角色调用doRandomAskEvent()方法,处理问号信息,
处理完毕后调用sendMSGDealAroundLand()方法发送MSG_AROUND_LAND消息,处理角色相邻上下左右地块的消息,缴纳过路费或购买升级地块。
void GameBaseScene::receivedNotificationOMsg(Object* data) { …………….. case MSG_RANDOM_ASK_EVENT_TAG: { int playerTag = messageVector.at(3)->intValue(); switch(playerTag) { case PLAYER_1_TAG: { doRandomAskEvent(player1); scheduleOnce(schedule_selector( GameBaseScene::sendMSGDealAroundLand),TOAST_SHOW_TIME); break; } case PLAYER_2_TAG: { doRandomAskEvent(player2); scheduleOnce(schedule_selector( GameBaseScene::sendMSGDealAroundLand),TOAST_SHOW_TIME); break; } } break; } ……………. }
void GameBaseScene::sendMSGDealAroundLand(float dt) { NotificationCenter::getInstance()->postNotification(MSG_AROUND_LAND,String::createWithFormat("%d",MSG_AROUND_LAND_TAG)); }
5、处理问号信息的方法doRandomAskEvent(),就是从问号容器中随机取出一个,根据事件进行资金或体力的增减,并Toast提示事件信息
void GameBaseScene::doRandomAskEvent(RicherPlayer* player) { int randomNumber = rand()%(randomAskEventMap.size()) + 1; __String * str = randomAskEventMap.at(randomNumber); switch(randomNumber) { case TAX_REBATES_TAG: { refreshMoneyLabel(player,10000); break; } case PAY_TAXES_TAG: { refreshMoneyLabel(player,-20000); break; } case LOSS_STRENGTH_TAG: { refreshStrengthLabel(player,-100); break; } case PHYSICAL_RECOVERY_TAG: { refreshStrengthLabel(player,100); break; } case INVESTMENT_DIVIDENDS_TAG: { refreshMoneyLabel(player,20000); break; } case INVESTMENT_LOSS_TAG: { refreshMoneyLabel(player,-30000); break; } } CocosToast::createToast(this, str->getCString(), TOAST_SHOW_TIME,player->getPosition()); }
6、RicherGameController.cpp中注册了MSG_AROUND_LAND消息观察者,收到该消息后调用aroundLandEvent() ,处理过路费或购买地块等问题
void RicherGameController::registerNotificationObserver() { ……………………. NotificationCenter::getInstance()->addObserver( this, callfuncO_selector(RicherGameController::receivedMsg), MSG_AROUND_LAND, NULL); } void RicherGameController::receivedMsg(Object* data) { …………………… if(retMsgType == MSG_AROUND_LAND_TAG) { aroundLandEvent(); } }
