哇！板球 源码分析四

小球与道具碰撞

小球进了网后得分效果

遍历小球

for(int i=0;i<arr->count();i++)//遍历小球{//从arr获取每个小球及当前位置BallTest* temp =(BallTest*)arr->objectAtIndex(i);CCPoint ballPoint = temp->getPosition();

遍历守门员

for(int j=0;j<array->count();j++)//遍历守门员{//从array获取每个守门员及当前位置FielderSprite* tempSprite = (FielderSprite*)array->objectAtIndex(j);CCPoint fielderPoint = tempSprite->getPosition();

如果吃到第三种道具， 从左至扫描出火效果， 当道的守门员全部移除

if(blurFlag){CCPoint firePoint = fire[1]->getPosition();if(fielderPoint.x-firePoint.x<10){array->removeObject(tempSprite);this->removeChild(tempSprite);}}

遍历道具，检测小球与道具是否是碰撞，吃到不同的道具有不同的威力

for(int k=0;k<pArr->count();k++)//遍历道具{Prop* pTemp =(Prop*)pArr->objectAtIndex(k);CCPoint propPoint = pTemp->getPosition();//吃到道具, 小球碰撞到道具if(abs(propPoint.x-ballPoint.x)<17&&abs(propPoint.y-ballPoint.y)<27){int m = pTemp->mark;//判断吃到什么道具, 共3种道switch(m){case 0:if(temp->mark!=1)//第1种道具，是带火的球加火{temp->setMark(1);}break;case 1:stopFielder();//第2种道具，停止守门员运动break;case 2:outFire(); //第3种道具， 从左至扫描出火效果break;}//吃到道具 道具消失pTemp->stopAllActions();pArr->removeObject(pTemp);this->removeChild(pTemp);}}

//第二种道具停止守门员运动void BanQiuLayer::stopFielder(){for(int j=0;j<array->count();j++)//守门员{FielderSprite* tempSprite = (FielderSprite*)array->objectAtIndex(j);tempSprite->stopAction(tempSprite->ccat);//black 守门员停止stArr->addObject(tempSprite);//添加到停止数组里tempSprite->stopTime=getCurrentTime();}}

//第三种道具从左至扫描出火效果void BanQiuLayer::outFire(){blurFlag = true;//第三种道具置成trueCCParticleSystem* cps = CCParticleSun::create();cps->retain();cps->setPosition( ccp( 0, 7) );cps->setLife(0.01f);for(int i=0;i<48;i++){fire[i]=CCSprite::create("pic/fire_2.png");fire[i]->setPosition(ccp(50,10*i));addChild(fire[i],GAME_LEVEL_WYF);fire[i]->addChild(cps, GAME_LEVEL_WYF);CCActionInterval* cs = CCMoveTo::create(1,CCPointMake(830,10*i));CCDelayTime *delay = CCDelayTime::create(3);fire[i]->runAction(CCSequence::create(cs,delay,CCCallFuncND::create(this, callfuncND_selector(BanQiuLayer::removeBlur), NULL),NULL));}}

检测到小球与移动的守门员碰撞了,碰撞了有回弹效果

if(abs(fielderPoint.x-ballPoint.x)<17&&abs(fielderPoint.y-ballPoint.y)<27){//若碰到守门员则反弹float vx = temp->x;float vy = temp->y;int mark = temp->getMark();if(temp->mark==0)//判断为普通的球{//第一次碰到守门员把小球碰撞标志位置成falseif(temp->getHitFlag()){temp->setHitFlag(false);tempCount++;//球被挡次数加1char a[4];snprintf(a, 4, "%d",tempCount);overLabel->setString(a);}if(tempCount==(this->targetCount)+1-guanka)//撞到守门员的次等于生命数，则失败{mag->toLoseLayer(tempScore,guanKa);//if(MUSIC){//播放失败音乐CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect("sound/failure.mp3");}}//temp->stopAllActions();//temp->cleanup();temp->stopAction(seq);//停止以前的动作

创建反弹的动作

CCActionInterval* back=CCMoveBy::create(OUTBALL_T,CCPointMake(-BALL_V*vx,BALL_V*vy));CCSequence* atBack = CCSequence::create(back,CCCallFuncND::create(this, callfuncND_selector(BanQiuLayer::removeBall), NULL),NULL);temp->runAction(back);

判断当前小球的进了哪个网

if(ballPoint.x<GRID_ONE_BOTTOM_X&&ballPoint.x>GRID_ONE_BOTTOM_X-GRID_WIDTH+GRID_OFFSET&&ballPoint.y<GRID_ONE_BOTTOM_Y+GRID_HEIGHT&&ballPoint.y>GRID_ONE_BOTTOM_Y)//若进了下面1号网{//移除小球this->removeChild(temp);arr->removeObject(temp);plussScore(GRID_ONE_BOTTOM_X-GRID_WIDTH/2,GRID_ONE_BOTTOM_Y+GRID_HEIGHT,GRID_ONE_BOTTOM_INDEX);}else if(ballPoint.x<GRID_ONE_TOP_X&&ballPoint.x>GRID_ONE_TOP_X-GRID_WIDTH&&ballPoint.y<GRID_ONE_TOP_Y&&ballPoint.y>GRID_ONE_TOP_Y-GRID_HEIGHT)//若进了上面1号网{//移除小球this->removeChild(temp);arr->removeObject(temp);plussScore(GRID_ONE_TOP_X-GRID_WIDTH/2,GRID_ONE_TOP_Y-GRID_HEIGHT,GRID_ONE_TOP_INDEX);}else if(ballPoint.x<GRID_TWO_BOTTOM_X&&ballPoint.x>GRID_TWO_BOTTOM_X-GRID_WIDTH&&ballPoint.y<GRID_TWO_BOTTOM_Y+GRID_HEIGHT&&ballPoint.y>GRID_TWO_BOTTOM_Y)//若进了下面2号网{//移除小球this->removeChild(temp);arr->removeObject(temp);plussScore(GRID_TWO_BOTTOM_X-GRID_WIDTH/2,GRID_TWO_BOTTOM_Y+GRID_HEIGHT,GRID_TWO_BOTTOM_INDEX);}else if(ballPoint.x<GRID_TWO_TOP_X&&ballPoint.x>GRID_TWO_TOP_X-GRID_WIDTH&&ballPoint.y<GRID_TWO_TOP_Y&&ballPoint.y>GRID_TWO_TOP_Y-GRID_HEIGHT)//若进了上面2号网{//移除小球this->removeChild(temp);arr->removeObject(temp);plussScore(GRID_TWO_TOP_X-GRID_WIDTH/2,GRID_TWO_TOP_Y-GRID_HEIGHT,GRID_TWO_TOP_INDEX);}else if(ballPoint.x>GRID_SIX_X-GRID_HEIGHT&&ballPoint.y<GRID_SIX_Y+GRID_WIDTH/2&&ballPoint.y>GRID_SIX_Y-GRID_WIDTH/2+GRID_OFFSET)//若进了6号网{//移除小球this->removeChild(temp);arr->removeObject(temp);plussScore(GRID_SIX_X-GRID_HEIGHT,GRID_SIX_Y, GRID_SIX_INDEX);}

进网后加分效果，plussScore函数处理

void BanQiuLayer::plussScore(float x,float y,int index)//参数顺序：分值起点x轴，及y轴，进入的几号网调用及移动轨迹动作

定义5条移动的轨迹线

进入几号网，创建相应的分值精灵，并运行其轨迹动作

CCSprite *sixSprite=NULL;switch(index){case 1:sixSprite = CCSprite::create("pic/score_1.png");sixSprite->runAction(one);break;case 2:sixSprite = CCSprite::create("pic/score_1.png");sixSprite->runAction(oneDown);break;case 3:sixSprite = CCSprite::create("pic/score_2.png");sixSprite->runAction(two);break;case 4:sixSprite = CCSprite::create("pic/score_2.png");sixSprite->runAction(two);break;case 5:sixSprite = CCSprite::create("pic/score_6.png");sixSprite->runAction(six);break;}//设置精灵对象的位置sixSprite->setPosition(ccp(x,y));//将精灵添加到布景中this->addChild(sixSprite, BACKGROUND_LEVEL_WYF);
