Cocos2d-x 3.2 大富翁游戏项目开发-第二十一部分 捡到积分卡 恢复体力
跟前面第18部分处理，问号事件一样，角色行走完毕后，还要检查停留问题是否有积分卡，如果有则增加相应的体力值
1、新建Item_strength_up类，该类用来显示角色体力回升的动画。
void Item_strength_up::addItemSpriteFrameCache()
{itemSpriteFrameCache = SpriteFrameCache::getInstance();itemSpriteFrameCache->addSpriteFramesWithFile("images/strength_up.plist","images/strength_up.png");memset(name, 0, 20);for (int i=1; i<=14; i++) {sprintf(name, "strength_up_%02d.png",i);item_anim_vector.pushBack(itemSpriteFrameCache->getSpriteFrameByName(name));}}void Item_strength_up::setItemAnimate()
{if(!AnimationCache::getInstance()->getAnimation("strength_up_animation")){AnimationCache::getInstance()->addAnimation(Animation::createWithSpriteFrames(item_anim_vector,0.1f),"strength_up_animation");}normal_anmi = Animate::create(AnimationCache::getInstance()->getAnimation("strength_up_animation"));normal_anmi->retain();
}2、在RicherGameController类的handlePropEvent方法中，添加积分卡的判断，如果停留位置有积分卡，则发送增加体力的MSG_STRENGTH_UP消息
void RicherGameController::handlePropEvent()
{
.........if(endId == GameBaseScene::strength_30_tiledID){String * str = String::createWithFormat("%d-%f-%f-%d",MSG_STRENGTH_UP30_TAG,pointInMap.x,pointInMap.y,_richerPlayer->getTag());NotificationCenter::getInstance()->postNotification(MSG_STRENGTH_UP,str);return;}if(endId == GameBaseScene::strength_50_tiledID){String * str = String::createWithFormat("%d-%f-%f-%d",MSG_STRENGTH_UP50_TAG,pointInMap.x,pointInMap.y,_richerPlayer->getTag());NotificationCenter::getInstance()->postNotification(MSG_STRENGTH_UP,str);return;}if(endId == GameBaseScene::strength_80_tiledID){String * str = String::createWithFormat("%d-%f-%f-%d",MSG_STRENGTH_UP80_TAG,pointInMap.x,pointInMap.y,_richerPlayer->getTag());NotificationCenter::getInstance()->postNotification(MSG_STRENGTH_UP,str);return;}}3、GameBaseScene中继续注册增加体力值的观察以及处理代码
void GameBaseScene::registerNotificationObserver()
{
.............NotificationCenter::getInstance()->addObserver(this,callfuncO_selector(GameBaseScene::receivedNotificationOMsg),MSG_STRENGTH_UP,NULL);
}receivedNotificationOMsg调用doItemStrengthUp方法，来具体处理体力值增加和体力恢复动画的播放
void GameBaseScene::receivedNotificationOMsg(Object* data)
{
.............case MSG_STRENGTH_UP30_TAG:{doItemStrengthUp(MSG_STRENGTH_UP30_TAG, messageVector.at(3)->intValue());break;}case MSG_STRENGTH_UP50_TAG:{doItemStrengthUp(MSG_STRENGTH_UP50_TAG, messageVector.at(3)->intValue());break;}case MSG_STRENGTH_UP80_TAG:{doItemStrengthUp(MSG_STRENGTH_UP80_TAG, messageVector.at(3)->intValue());break;}}4、体力动画播放完毕后，调用发送消息 sendMSGDealAroundLand ，来处理角色上下左右相邻地块事件
void GameBaseScene::doItemStrengthUp(int strengthUp,int playerTag)
{int strengthValue = 0;//根据积分卡值，给strengthValue赋相应值switch(strengthUp){case MSG_STRENGTH_UP30_TAG:{strengthValue =30; break;}case MSG_STRENGTH_UP50_TAG:{strengthValue =50;break;}case MSG_STRENGTH_UP80_TAG:{strengthValue =80;break;}}switch(playerTag){case PLAYER_1_TAG:{//设置item_strength_up在角色的位置可见，播放动画,显示toast。播放完毕设置item_strength_up不可见item_strength_up->setVisible(true);item_strength_up->setPosition(player1->getPosition()-ccp(5,0));Sequence* action = Sequence::create(item_strength_up->getNormal_anmi(),CallFunc::create([this](){item_strength_up->setVisible(false);}),NULL);item_strength_up->runAction(action);CocosToast::createToast(this, String::createWithFormat("%s %d",LanguageString::getInstance()->getLanguageString(STRENGTH_UP)->getCString(),strengthValue)->getCString(),TOAST_SHOW_TIME,player1->getPosition()); refreshStrengthLabel(player1,strengthValue);scheduleOnce(schedule_selector( GameBaseScene::sendMSGDealAroundLand),3.0f);break;}case PLAYER_2_TAG:{.............} }}
效果如图
