分享一個《捕魚》的用戶端遊戲，《捕魚》用戶端

　　今天一天用cocos2d做了一個捕魚系統的demo，資源取自廣為流傳的android小遊戲叫做年年有餘，哎，無論叫做什麼吧！之前是用android寫的，今天一天用cocos2d從新寫了一遍！大家可以用來做為學習cocos2d的demo，或者開發自己捕魚系統的demo！

　　先來幾張片：

　　

　　玩法很簡單，用手按住魚，魚就被抓緊了網內，然後再網破掉之前，將魚放到魚缸！就這樣！

　　下面對代碼進行解析：

　　首先定義Fish類：

//Fish 標頭檔#pragma once#include "cocos2d.h"#include "cocos-ext.h"#include <vector>using namespace std;using namespace cocos2d;using namespace cocos2d::extension;class Fish : public CCSprite{public:Fish(void);~Fish(void);bool init();CCPoint getPoint();void wander();int get_score();void setCoord(int x,int y);private:int image_index ;double coord_x;double coord_y;CCSprite* _image;vector<CCTexture2D*> _textture_vec;int fish_num;};//Fish 實現代碼：#include "Fish.h"#include "GameStruct.h"Fish::Fish(void){this->fish_num = rand()%3;this->_image = NULL;this->coord_x = rand()%200;this->coord_y = rand()%200;this->image_index = 0;}Fish::~Fish(void){}bool Fish::init(){CCSprite::init();this->_image = CCSprite::create(fish_image[this->fish_num][0].c_str());this->setContentSize(CCSize(60,16));this->_image->setPosition(CCPoint(30,8));this->addChild(this->_image);for(int i = 0;i<3;i++){CCSprite * temp_obj = CCSprite::create(fish_image[this->fish_num][i].c_str());  CCTexture2D *hero_hit = temp_obj->getTexture();  this->_textture_vec.push_back(hero_hit);}return true;}void Fish::setCoord(int x,int y){this->coord_x = x;this->coord_y = y;}int Fish::get_score(){return this->image_index*2 + 1;}void Fish::wander(){this->image_index ++;if(this->image_index >= 3){this->image_index = 0;}this->_image->setTexture(this->_textture_vec.at(this->image_index));float degrees = rand()/rand();this->setRotation(degrees);int len = 6;double len_x = len*sin(degrees);double len_y = len*cos(degrees);this->coord_x += len_y;this->coord_y += len_x;}CCPoint Fish::getPoint(){return CCPoint(coord_x,coord_y);}

 　　Fish，就是魚，繼承自CCSprite，最終要的一個函數就是wander()；用來實現魚在魚池中遊盪！首先先隨機出一個角度來，然後再對Fish進行旋轉(rotate)，然後再向著頭部的防線行走！更新x，y座標！再移動的同時，要不斷變換魚的圖片，因為尾巴要不斷的擺動嗎！

　　然後就是FishNet類，故名思議，漁網類

//標頭檔#pragma once#include "cocos2d.h"#include "cocos-ext.h"#include "Fish.h"#include <vector>using namespace std;using namespace cocos2d;using namespace cocos2d::extension;class HelloWorld;#define FISHNETSIZECCSize(90,90)class FishNet :public CCSprite{public:FishNet(HelloWorld* scene);~FishNet(void);bool init();void add_fish(Fish* fish);void reset();void update(float tick);void enable();void disable();bool is_enable();void scatter();void recycle();private:int _image_index;CCSprite* _image;vector<CCTexture2D*> _textture_vector;vector<Fish*> fish_vect;bool _enable;HelloWorld* _scene;};//實現代碼#include "FishNet.h"#include "HelloWorldScene.h"#include "GameStruct.h"FishNet::FishNet(HelloWorld* scene){this->_image = NULL;this->_image_index = 0;this->_enable = false;this->_scene = scene;}FishNet::~FishNet(void){}void FishNet::reset(){this->_image_index = 0;}bool FishNet::init(){CCSprite::init();this->setContentSize(FISHNETSIZE);this->_image = CCSprite::create("fish_net0.png");this->_image->setPosition(CCSize(FISHNETSIZE.width/2,FISHNETSIZE.height/2));this->addChild(this->_image);for(int i=0;i<7;i++){CCSprite* image = CCSprite::create(fish_net_image[i].c_str());CCTexture2D *textture = image->getTexture();this->_textture_vector.push_back(textture);}return true;}void FishNet::add_fish(Fish* fish){fish->setPosition(CCSize(FISHNETSIZE.width/2,FISHNETSIZE.height/2));this->fish_vect.push_back(fish);this->addChild(fish);}void FishNet::scatter(){for(vector<Fish*>::iterator iter = this->fish_vect.begin();iter != this->fish_vect.end();iter++){this->removeChild(*iter,true);//(*iter)->setPosition(this->getPosition());(*iter)->setCoord(this->getPositionX(),this->getPositionY());this->_scene->generate_fish(*iter);}this->fish_vect.clear();}void FishNet::recycle(){if(this->is_enable()){for(vector<Fish*>::iterator iter = this->fish_vect.begin();iter != this->fish_vect.end();iter++){this->removeChild(*iter,true);this->_scene->add_score((*iter)->get_score());}this->fish_vect.clear();}}void FishNet::update(float tick){this->_image_index ++;if(this->_image_index == 7){this->_image_index = 0;this->disable();return ;}this->_image->setTexture(this->_textture_vector.at(this->_image_index));}void FishNet::enable(){this->_enable = true;}void FishNet::disable(){this->_enable = false;this->scatter();this->_scene->recycle_fish_net();}bool FishNet::is_enable(){return this->_enable;}

 　  FIshNet同樣繼承子CCSprite，幾個注意的點：update函數，不斷更新漁網的狀態！scatter函數，當漁網破裂時，要將漁網裡面的魚全部釋放掉！recycle，當漁網達到魚缸時，並且漁網還沒有破裂，那麼玩家要得分！

　　下面是最核心的HelloWorld類，其實更加應該稱為池塘類，但是以為是在HelloWorld那個工程上修改了，所以就沒有調整！HelloWorld繼承子CCLayer!

 　　代碼中幾個函數體現的很明顯了！1：random_generate_fish:不斷的隨機產生新的魚；update ： 心跳函數，每秒執行5次，不斷驗證是否有魚出界，如果出界就回收掉！不斷判斷漁網是否到達魚缸，如果到達就回收掉漁網裡面的魚兒，並且給玩家加分！ 不斷驗證漁網是否破壞掉，如果已經損壞，就將漁網裡面的魚放到池塘裡面去！

　　感興趣的，可以問我要整個工程，原android版的也有！另外太久不寫C++了，命名和stl有點生疏了！

　　希望對大家有協助，原android工程的年年有餘項目，大家也可以找我！
