1. 写笔记主要是为了同强大的忘性作斗争，学习《Cocos2d-x 3.x游戏开发之旅》所记。
2. 以下参照书本，跑出来的效果图，所以主要还是把代码贴上来，方便日后查询。
3.下面开始贴代码
创建基类，为人物和金币所继承.Entity 继承与Node.
#ifndef _ENTITY_H_#define _ENTITY_H_#include"cocos2d.h"USING_NS_CC;class Entity : public Node{public: Entity(); ~Entity(); Sprite* getSprite(); voID bindSprite(Sprite* sprite);private: Sprite* m_sprite;};#endif#include"Entity.h"#include"Player.h"Entity::Entity(){ m_sprite = NulL;}Entity::~Entity(){}Sprite* Entity::getSprite(){ return this->m_sprite;}voID Entity::bindSprite(Sprite* sprite){ this->m_sprite = sprite; this->addChild(m_sprite); /*由于需要做碰撞检测，而Node的默认宽高属性（0,0），所以需要获取精灵的宽高，设置给Entity.这样Entity就有了Sprite对象的宽高。*/ Size size = m_sprite->getContentSize(); m_sprite->setposition(Point(size.wIDth*0.5f,size.height*0.5f)); this->setContentSize(size);} 2.创建主角类Player和金币类Monster.
#ifndef _PLAYER_H_#define _PLAYER_H_#include"cocos2d.h"#include"Entity.h"using namespace cocos2d;#define JUMP_ACTION_TAG 1class Player : public Entity{public: Player(); ~Player(); CREATE_FUNC(Player); virtual bool init(); voID jump(); voID hit(); int getiHP(); voID resetData();private: bool b_isJumPing; int m_iHP;};#endif#include"Player.h"//#include"FlowWord.h"Player::Player(){ b_isJumPing = false; m_iHP = 1000;}Player::~Player(){}bool Player::init(){ return true;}voID Player::hit()//碰撞时，人物的动作{ if(getSprite() == NulL) { return; } m_iHP -= 15; if(m_iHP < 0) { m_iHP = 0; } //FlowWord* flowWord = FlowWord::create(); //this->addChild(flowWord); //flowWord->showWord("-15",GetSpoolfileHandle); auto backMove = MoveBy::create(0.1f,Point(-20,0)); auto forwardMove = MoveBy::create(0.1f,Point(20,0)); auto backRotate = RotateBy::create(0.1f,-5,0); auto forwardRotate = RotateBy::create(0.1f,5,0); auto backAction = Spawn::create(backMove,backRotate,NulL); auto forwardAction = Spawn::create(forwardMove,forwardRotate,NulL); auto actions = Sequence::create(backAction,forwardAction,NulL); stopAllActions(); resetData(); runAction(actions);}voID Player::resetData(){ if(b_isJumPing) { b_isJumPing = false; } setposition(Point(200,140)); setScale(1.0f); setRotation(0);}int Player::getiHP(){ return m_iHP;}voID Player::jump(){ if(getSprite() == NulL) return; if(b_isJumPing) return; b_isJumPing = true; auto jump = JumpBy::create(2.0f,Point(0,0),250,1);//原地跳跃，高度250像素，跳跃一次 auto callFunc = CallFunc::create([&]() { b_isJumPing = false; }); auto jumpAction = Sequence::create(jump,callFunc,NulL); this->runAction(jumpAction);}<pre name="code" >#ifndef _MONSTER_H_#define _MONSTER_H_#include"Entity.h"#include"Player.h"class Monster:public Entity{public: Monster(); ~Monster(); CREATE_FUNC(Monster); virtual bool init();public: voID show(); voID hIDe(); voID reset(); bool isAlive(); bool isCollIDeWithPlayer(Player* player);private: bool b_isAlive;};#endif#include"Monster.h"Monster::Monster(){ b_isAlive = false;}Monster::~Monster(){}bool Monster::init(){ return true;}voID Monster::show(){ if(getSprite() != NulL) { setVisible(true); b_isAlive = true; }}voID Monster::hIDe(){ if(getSprite() != NulL) { setVisible(false); reset(); b_isAlive = false; }}voID Monster::reset(){ if(getSprite() != NulL) { setposition(Point(800+CCRANDOM_0_1() * 2000,200-CCRANDOM_0_1()*100)); }}bool Monster::isAlive(){ return b_isAlive;}bool Monster::isCollIDeWithPlayer(Player* player){ if(player == NulL || getSprite() == NulL) return false; Rect entityRect = player->getBoundingBox();//获取碰撞检测对象的boundingBox Point monsterPos = getposition(); return entityRect.containsPoint(monsterPos);} 3.金币管理类，负责金币的创建，管理。
#ifndef _MANAGERMONSTER_H_#define _MANAGERMONSTER_H_#include "cocos2d.h"#include "Monster.h"USING_NS_CC;#define MAX_MONSTER_NUM 10class MonsterManager:public Node{public: CREATE_FUNC(MonsterManager); virtual bool init(); virtual voID update(float dt);private : voID createMonster();public: voID bindplayer(Player* player);private: Vector<Monster*> m_monsterarr;//Vector容器的应用 Player* m_player;};#endif#include"MonsterManager.h"#include"Player.h"#include"Monster.h"bool MonsterManager::init(){ createMonster(); this->scheduleUpdate(); return true;}voID MonsterManager::createMonster(){ Monster* monster = NulL; Sprite* sprite = NulL; for(int i = 0; i < MAX_MONSTER_NUM; i++) { monster = Monster::create(); monster->bindSprite(Sprite::create("monster.png")); monster->reset(); this->addChild(monster); m_monsterarr.pushBack(monster); }} voID MonsterManager::update(float dt) { for(auto monster:m_monsterarr) { if(monster == NulL) continue; if(monster->isAlive()) { monster->setpositionX(monster->getpositionX() - 4); if(monster->getpositionX() < 0) { monster->hIDe(); } } else { monster->show(); } if(monster->getpositionX() < 0) { monster->hIDe(); } else if(monster->isCollIDeWithPlayer(m_player)) { m_player->hit(); monster->hIDe(); } } } voID MonsterManager::bindplayer(Player* player) { m_player = player; } 4.创建场景类
