添加不同的怪物，这个是我从其他地方实现的。
添加Monster.h和Monster.cpp
开始的时候我是继承的CCSprite，但是一直出问题。在网上发现可以继承CCNode，就尝试了一下。
1 // 2 // Monster.h 3 // cocos2d-x_simpleGame_20131104 4 // 5 // Created by 张学院 on 14-1-13. 6 // 7 // 8 9 #ifndef __cocos2d_x_simpleGame_20131104__Monster__ 10 #define __cocos2d_x_simpleGame_20131104__Monster__ 11 12 #include <iostream> 13 #include "cocos2d.h" 14 class Monster:public cocos2d::CCNode{ 15 public : 16 int _curHp; 17 int minMove; 18 int maxMove; 19 cocos2d::CCSprite * m_sprite; 20 public : 21 Monster(); 22 ~Monster(); 23 void bindSprite(cocos2d::CCSprite * sprite); 24 25 int gethp(); 26 void sethp(int hp); 27 int getminMove(); 28 void setminMove(int minMove); 29 int getmaxMove(); 30 void setmaxMove(int maxMove); 31 32 }; 33 class WeakAndFastMoveMonster:public Monster{ 34 35 public: 36 static WeakAndFastMoveMonster * monster(); 37 }; 38 class StrongAndSlowMonster:public Monster{ 39 public : 40 41 static StrongAndSlowMonster * monster(); 42 43 44 }; 45 #endif /* defined(__cocos2d_x_simpleGame_20131104__Monster__) */
1 // 2 // Monster.cpp 3 // cocos2d-x_simpleGame_20131104 4 // 5 // Created by 张学院 on 14-1-13. 6 // 7 // 8 9 #include "Monster.h" 10 Monster::Monster(){ 11 _curHp=0; 12 minMove=0; 13 maxMove=0; 14 m_sprite=NULL; 15 } 16 17 Monster::~Monster(){ 18 19 } 20 void Monster::bindSprite(cocos2d::CCSprite * sprite){ 21 m_sprite=sprite; 22 this->addChild(m_sprite); 23 } 24 void Monster::sethp(int hp){ 25 this->_curHp=hp; 26 27 } 28 void Monster::setmaxMove(int maxMove){ 29 this->maxMove=maxMove; 30 31 } 32 void Monster::setminMove(int minMove){ 33 this->minMove=minMove; 34 35 } 36 37 int Monster::gethp(){return _curHp; 38 } 39 40 int Monster::getmaxMove(){ return maxMove;} 41 int Monster::getminMove(){return minMove;} 42 43 WeakAndFastMoveMonster * WeakAndFastMoveMonster::monster(){ 44 WeakAndFastMoveMonster * target= new WeakAndFastMoveMonster(); 45 46 target->bindSprite(cocos2d::CCSprite::create("Target.png")); 47 48 target->sethp(1); 49 target->setmaxMove(5); 50 target->setminMove(3); 51 52 53 54 return target; 55 } 56 StrongAndSlowMonster * StrongAndSlowMonster::monster(){ 57 StrongAndSlowMonster * target= new StrongAndSlowMonster(); 58 59 target->bindSprite(cocos2d::CCSprite::create("Target2.png")); 60 target->sethp(3); 61 target->setmaxMove(6); 62 target->setminMove(12); 63 64 65 return target; 66 }
修改HelloWorldScene.cpp 中的addTarget方法
1 void HelloWorld::addTarget(){ 2 3 //CCSprite *target= CCSprite::create("Target.png",CCRectMake(0, 0, 27, 40) ); 4 //Monster *monster; 5 Monster *target; 6 7 if((rand()%2==0)){ 8 target=WeakAndFastMoveMonster::monster(); 9 }else{ 10 target=StrongAndSlowMonster::monster(); 11 } 12 13 target->setTag(1); 14 _targets->addObject(target); 15 16 CCSize winSize = CCDirector::sharedDirector()->getWinSize(); 17 18 19 int minY= target ->getContentSize().height/2; 20 int maxY=winSize.height-target->getContentSize().height/2; 21 int rangeY= maxY-minY; 22 //随机生成y坐标 23 int actualY = (rand() %rangeY)+minY; 24 target->setPosition(ccp(winSize.width+(target->getContentSize().width/2),actualY)); 25 this->addChild(target); 26 27 int minDuration = target->getminMove(); 28 int maxDuration = target->getmaxMove(); 29 // Determine speed of the target 30 // int minDuration = (int)3.0; 31 // int maxDuration = (int)5.0; 32 int rangeDuration = maxDuration - minDuration; 33 // srand( TimGetTicks() ); 34 //随机生产移动速度。 35 int actualDuration = ( rand() % rangeDuration ) 36 + minDuration; 37 38 // Create the actions 39 40 CCFiniteTimeAction* actionMove = 41 CCMoveTo::create( (float)actualDuration, 42 ccp(0 - target->getContentSize().width/2, actualY) ); 43 // 增加回掉函数，收回内存 44 CCFiniteTimeAction* actionMoveDone = 45 CCCallFuncN::create( this, 46 callfuncN_selector(HelloWorld::spriteMoveFinished)); 47 48 CCLOG("before runAction"); 49 //target执行动画 50 target->runAction( CCSequence::create(actionMove,actionMoveDone, NULL) ); 51 52 CCLOG("after runAction"); 53 54 }
修改碰撞函数update方法
1 void HelloWorld::update(float dt){ 2 monsterHit=false; 3 CCArray *projectilesToDelete = new CCArray; 4 CCArray* targetsToDelete =new CCArray; 5 CCObject* it = NULL; 6 CCObject* jt = NULL; 7 8 CCARRAY_FOREACH(_projectiles, it) 9 { 10 CCSprite *projectile = dynamic_cast<CCSprite*>(it); 11 12 CCRect projectileRect = CCRectMake( 13 projectile->getPosition().x - (projectile->getContentSize().width/2), 14 projectile->getPosition().y - (projectile->getContentSize().height/2), 15 projectile->getContentSize().width, 16 projectile->getContentSize().height); 17 18 CCARRAY_FOREACH(_targets, jt) 19 { 20 Monster *target = dynamic_cast<Monster*>(jt); 21 CCRect targetRect = CCRectMake( 22 target->getPosition().x - (target->getContentSize().width/2), 23 target->getPosition().y - (target->getContentSize().height/2), 24 target->getContentSize().width, 25 target->getContentSize().height); 26 27 if (projectileRect.intersectsRect(targetRect)) 28 { 29 // targetsToDelete->addObject(target); 30 monsterHit=true; 31 target->_curHp--; 32 if(target->gethp()<=0){ 33 targetsToDelete->addObject(target); 34 } 35 36 projectilesToDelete->addObject(projectile); 37 break; 38 } 39 } 40 } 41 42 CCARRAY_FOREACH(targetsToDelete, jt) 43 { 44 Monster *target = dynamic_cast<Monster*>(jt); 45 46 _targets->removeObject(target); 47 _projectilesDestroyed++; 48 if (_projectilesDestroyed >= 20) 49 { 50 GameOverScene *gameOverScene = GameOverScene::create(); 51 gameOverScene->getLayer()->getLabel()->setString("You Win!"); 52 CCDirector::sharedDirector()->replaceScene(gameOverScene); 53 } 54 this->removeChild(target, true); 55 } 56 57 CCARRAY_FOREACH(projectilesToDelete, it) 58 { 59 60 CCSprite* projectile = dynamic_cast<CCSprite*>(it); 61 _projectiles->removeObject(projectile); 62 this->removeChild(projectile, true); 63 64 } 65 66 projectilesToDelete->release(); 67 targetsToDelete->release(); 68 }
对了，在HelloWorldScene.cpp中添加了一个bool monsterHit.
