Cocos2d-x 3.2 大富翁游戏项目开发-第二十二部分 拾到珍珠

bool Item_ball::init() { addItemSpriteFrameCache(); SpriteFrame* spf; spf = itemSpriteFrameCache->getSpriteFrameByName("ball_01.png"); Sprite::initWithSpriteFrame(spf); setItemAnimate(); return true; } void Item_ball::addItemSpriteFrameCache() { itemSpriteFrameCache = SpriteFrameCache::getInstance(); itemSpriteFrameCache->addSpriteFramesWithFile("images/ball.plist","images/ball.png"); memset(name, 0, 20); for (int i=1; i<=3; i++) { sprintf(name, "ball_%02d.png",i); item_anim_vector.pushBack(itemSpriteFrameCache->getSpriteFrameByName(name)); } } void Item_ball::setItemAnimate() { if(!AnimationCache::getInstance()->getAnimation("ball_animation")) { AnimationCache::getInstance()->addAnimation(Animation::createWithSpriteFrames(item_anim_vector,0.4f),"ball_animation"); } normal_anmi = Animate::create(AnimationCache::getInstance()->getAnimation("ball_animation")); normal_anmi->retain(); }

2、GameBaseScene的initItemSprite方法添加了item_ball对象 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); item_ball = (Item_ball*)Item::create(ITEM_BALL); addChild(item_ball); item_ball->runAction(RepeatForever::create(item_ball->getNormal_anmi())); item_ball->setVisible(false); ................. }

3、updateBlockWaySprites方法更新珍珠的位置 void GameBaseScene::updateBlockWaySprites(float dt) { ................ int _rand2 = rand()%(wayLayerPass_vector.size()); Vec2 position2 = wayLayerPass_vector.at(_rand2); item_ball->setVisible(true); item_ball->setPosition(position2); item_ball->setAnchorPoint(ccp(0,0)); }

4、 当停留位置是珍珠时，toast显示信息，显示终了后调用sendMSGDealAroundLand2方法，继续处理上下左右相邻地块信息 void GameBaseScene::doBlockWayEvent(RicherPlayer* player) { ............. else if(player->getBoundingBox().intersectsRect(item_ball->getBoundingBox())) { item_ball->setPosition(ccp(⑵00,⑵00)); int money = 10000; refreshMoneyLabel(player,money); CocosToast::createToast(this,String::createWithFormat("%s %d",LanguageString::getInstance()->getLanguageString(PICK_BALL)->getCString(),money)->getCString(),TOAST_SHOW_TIME,player->getPosition(),(SEL_CallFun)&GameBaseScene::sendMSGDealAroundLand2); } ........... } void GameBaseScene::sendMSGDealAroundLand2() { NotificationCenter::getInstance()->postNotification(MSG_AROUND_LAND,String::createWithFormat("%d",MSG_AROUND_LAND_TAG)); }
