該部份我們添加螃蟹傷人事件，道路位置隨機添加螃蟹精靈，當角色行走終了如果停留位置碰到了螃蟹，首先播放傷人動畫，然后是播放救護車把角色帶走動畫。
如果輪番到該角色行走時，吐司提示住院還有幾天，當住院天數到期，該角色才可以繼續行走
新建了幾個精靈類
Item_crab.cpp 螃蟹
Item_emergency.cpp 救護車
Item_fog.cpp 煙霧
Item_stretcher.cpp 擔架
//該方法在場景中添加這幾個精靈
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));
}
定義了定時器，每隔100秒調用該方法，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 屬性，記錄受傷后，角色需要住院停留的回合數
2、修改void RicherGameController::endGo()方法
當角色行走終了，發送MSG_BLOCK_WAY_EVENT消息，該消息用來處理行走終了后，檢查道路上是不是存在螃蟹等
void RicherGameController::endGo()
{
...........
if(stepHasGone >= stepsCount)
{
String * str = String::createWithFormat("%d-%f-%f-%d",MSG_BLOCK_WAY_EVENT_TAG,0.0f,0.0f,_richerPlayer->getTag());
NotificationCenter::getInstance()->postNotification(MSG_BLOCK_WAY_EVENT,str);
return;
}
.............
}
3、GameBaseScene.cpp注冊MSG_BLOCK_WAY_EVENT消息視察者
void GameBaseScene::registerNotificationObserver()
{
...........
NotificationCenter::getInstance()->addObserver(
this,
callfuncO_selector(GameBaseScene::receivedNotificationOMsg),
MSG_BLOCK_WAY_EVENT,
NULL);
............
}
4、receivedNotificationOMsg 具體處理該消息，根據角色調用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，就是根據角色判斷是不是碰到了螃蟹，如果碰到了，播放受傷等1系列動畫，動畫播放終了后，設置角色不可見，并發送MSG_PICKONE_TOGO消息，讓控制器取出下1個角色繼續行走。
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，設置螃蟹位置，讓其不可見
item_crab->setPosition(ccp(⑵00,⑵00));
//設置角色隨機停留回合數
player->restTimes = rand()%(5) + 1;;
log("doBlockWayEvent intersetcRect");
//救護車變成可見
emerg->setVisible(true);
//救護車從右往左移動的距離
int distance = tableStartPosition_x-player->getPosition().x;
//救護車的位置
emerg->setPosition(player->getPosition()+ccp(distance,0));
//螃蟹和角色打架的煙霧動畫
fog->setVisible(true);
fog->setPosition(player->getPosition());
Repeat* repeate0 = Repeat::create(fog->getNormal_anmi(),2);
fog->runAction(repeate0);
//救護車的移動動畫
MoveBy* moveBy = MoveBy::create(1.0f,ccp(-distance,0));
MoveBy* moveBy2 = MoveBy::create(0.5f,ccp(⑹0,0));
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,NULL),CallFunc::create(CC_CALLBACK_0(GameBaseScene::endCarGo, this)),NULL);
spawnAction->retain();
emerg->runAction(spawnAction);
//根據動畫播放的時間設置角色不可見
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顯示角色受傷住院天數信息
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
{
//如果沒有碰到螃蟹，角色繼續發送消息用于處理停留位置事件：是不是有問號時間，然后是上下左右相鄰位置房屋是不是需要購買升級繳納過路費等
NotificationCenter::getInstance()->postNotification(MSG_HANDLE_PROP_EVENT,String::createWithFormat("%d",MSG_HANDLE_PROP_EVENT_TAG));
}
}
//讓角色和打架煙霧動畫不可見
void GameBaseScene::setPlayer1InVisible(float dt)
{
player1->setVisible(false);
fog->setVisible(false);
}
void GameBaseScene::setPlayer2InVisible(float dt)
{
player2->setVisible(false);
fog->setVisible(false);
}
//救護車開來動畫結束后調用該函數，播放小黃人抬擔架動畫
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,ccp(⑹0,0));
Repeat* repeate2 = Repeat::create(strentcher->getStretcher_full_anmi(),1);
Sequence* spawnAction = Sequence::create(Spawn::create(moveBy,scaleBy,repeate,NULL),Spawn::create(moveBy2,scaleBy2,repeate2,NULL),CallFunc::create(CC_CALLBACK_0(GameBaseScene::startCarGoAgain, this)),NULL);
spawnAction->retain();
strentcher->runAction(spawnAction);
}
//小黃人抬擔架動畫播放終了后，播放救護車開走動畫
void GameBaseScene::startCarGoAgain()
{
strentcher->setVisible(false);
int distance = emerg->getPositionX();
MoveBy* moveBy = MoveBy::create(1.0f,ccp(-distance,0));
Repeat* repeate = Repeat::create(emerg->getCar_go_anmi(),5);
Sequence* spawnAction = Sequence::create(Spawn::create(moveBy,repeate,NULL),CallFunc::create(CC_CALLBACK_0(GameBaseScene::endCarGoLast, this)),NULL);
spawnAction->retain();
emerg->runAction(spawnAction);
}
//救護車開走后，調用該方法，讓救護車不可見，并發送MSG_PICKONE_TOGO消息，讓其他角色繼續行走
void GameBaseScene::endCarGoLast()
{
emerg->setVisible(false);
NotificationCenter::getInstance()->postNotification(MSG_PICKONE_TOGO,String::createWithFormat("%d",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);
//如果輪番到該角色行走，但是在受傷休息，則發送MSG_REST 休息消息
if(richerPlayer->getIsMyTurn() && richerPlayer->restTimes > 0 )
{
String * str = String::createWithFormat("%d-%f-%f-%d",MSG_REST_TAG,0.0f,0.0f,richerPlayer->getTag());
NotificationCenter::getInstance()->postNotification(MSG_REST,str);
return;
}
//如果輪番到角色行走，并且不在休息
if(richerPlayer->getIsMyTurn() && richerPlayer->restTimes == 0)
{
richerPlayer->setVisible(true);
//角色1 發送MSG_GO消息，顯示go按鈕
if(richerPlayer->getTag() == PLAYER_1_TAG )
{
NotificationCenter::getInstance()->postNotification(MSG_GO,String::createWithFormat("%d",MSG_GO_SHOW_TAG));
return;
}
//其他角色 獲得路徑，自動行走
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;
//走到這里，說明角色都行走終了，調用resetPlayerGoTurn方法，重新設置角色IsMyTurn為true等
resetPlayerGoTurn();
}
//每個回合結束后調用該方法，讓角色的restTimes 減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;
}
}
//發送MSG_ROUND_COUNT 更新回合數
NotificationCenter::getInstance()->postNotification(MSG_ROUND_COUNT,String::createWithFormat("%d",MSG_ROUND_COUNT_TAG));
//設置終了，繼續調用pickOnePlayerToGo ，進行下1輪行走
pickOnePlayerToGo();
}
7、GameBaseScene.cpp注冊MSG_REST消息視察者
void GameBaseScene::registerNotificationObserver()
{
...........
NotificationCenter::getInstance()->addObserver(
this,
callfuncO_selector(GameBaseScene::receivedNotificationOMsg),
MSG_REST,
NULL);
.............
}
8、處理MSG_REST消息
當收到休息的消息，首先設置IsMyTurn 為false，并吐司顯示還需要休息幾個回合，顯示結束后調用GameBaseScene::sendMSGPickOneToGO 方法，繼續下1個角色行走
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, String::createWithFormat("%s %d %s",LanguageString::getInstance()->getLanguageString(IN_HOSPITAL_REMAIN)->getCString(),player1->restTimes,LanguageString::getInstance()->getLanguageString(RICH_DAY)->getCString())->getCString(), TOAST_SHOW_TIME,player1->getPosition(),(SEL_CallFun)&GameBaseScene::sendMSGPickOneToGO);
break;
}
case PLAYER_2_TAG:
{
player2->setIsMyTurn(false);
CocosToast::createToast(this, String::createWithFormat("%s %d %s",LanguageString::getInstance()->getLanguageString(IN_HOSPITAL_REMAIN)->getCString(),player2->restTimes,LanguageString::getInstance()->getLanguageString(RICH_DAY)->getCString())->getCString(), TOAST_SHOW_TIME,player2->getPosition(),(SEL_CallFun)&GameBaseScene::sendMSGPickOneToGO);
break;
}
}
break;
}
..........
}
9、CocosToast.cpp 文件，添加了SEL_CallFun method 函數指針，用來調用傳進來的方法，如 GameBaseScene::sendMSGPickOneToGO 發送行走消息。
typedef void (Layer::*SEL_CallFun)();
void CocosToast::createToast(cocos2d::Node *node, const std::string &msg, const float &time,Vec2 point,SEL_CallFun method)；
10、當角色行走終了 停留位置的房屋所有者如果在住院，則免繳過路費。吐司提示，并調用GameBaseScene::sendMSGPickOneToGO 發送行走消息
void GameBaseScene::payTolls(int payTag,float x,float y ,int playerTag)
{
.............
if(landOwner->restTimes > 0)
{
CocosToast::createToast(this, LanguageString::getInstance()->getLanguageString(IN_HOSPITAL)->getCString(), TOAST_SHOW_TIME,player1->getPosition(),(SEL_CallFun)&GameBaseScene::sendMSGPickOneToGO);
return;
}
.............
}
