在不同的文件中创建精灵(在类中)

Question

我正在寻找帮助创建一个不同的类和文件cocos2d-x精灵。我已经使用了来自cocos2d-x网站的代码来实现精灵和其他帖子的子类化，但它对我不起作用。我按照声纳系统教程为一个"bird“精灵(在我的例子中是”Player“)创建了一个单独的类，但在尝试通过使用层参数的Player类构造函数传递helloworld层时遇到了错误。错误显示："' Player :: Player (const Player &)'：无法将参数1从'HelloWorld *const‘转换为'const Player &’ApocalypseWorld Player 39“

下面是代码: Player.h：

#pragma once
#include "cocos2d.h"

class Player
{
public:
 Player( cocos2d::Layer* layer );

private:
 cocos2d::Sprite *player1;
};

Player.cpp：

#include "Player.h"
#include "cocostudio/CocoStudio.h"
#include "ui/CocosGUI.h"

USING_NS_CC;

Player::Player( cocos2d::Layer* layer )
{

    player1 = Sprite::create("PlayerHead.png");
    player1->setPosition(Point(200, 200));

    layer->addChild(player1, 100);
}

HelloWorldScene.h：

#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__

#include "cocos2d.h"
#include "Player.h"

class HelloWorld : public cocos2d::Layer
{
public:
    // there's no 'id' in cpp, so we recommend returning the class instance pointer
    static cocos2d::Scene* createScene();

    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
    virtual bool init();

    Player* player;

    // implement the "static create()" method manually
    CREATE_FUNC(HelloWorld);
};

#endif // __HELLOWORLD_SCENE_H__

HelloWorldScene.cpp：

#include "HelloWorldScene.h"
#include "Player.h"
#include "cocostudio/CocoStudio.h"
#include "ui/CocosGUI.h"

USING_NS_CC;

using namespace cocostudio::timeline;

Scene* HelloWorld::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();

    // 'layer' is an autorelease object
    auto layer = HelloWorld::create();

    // add layer as a child to scene
    scene->addChild(layer);

    // return the scene
    return scene;
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }

    auto rootNode = CSLoader::createNode("MainScene.csb");

    addChild(rootNode);

player = new Player(this);


return true;

}

我在t下面画了一条小红线：

player = new Player(this); 

在HelloWorldScene.cpp文件的末尾

编辑代码：

Player.h：

#ifndef __Sample__Player__
#define __Sample__Player__

#include "cocos2d.h"

USING_NS_CC;

class Player : public Node
{
public:
    static Player* createPlayer(Layer* layer);

    Sprite* head;
};

#endif

Player.cpp：

#include "Player.h"

Player* Player::createPlayer(Layer* layer) {
    auto ret = new (std::nothrow) Player;
    if(ret && ret->init()) {
        ret->autorelease();
        ret->head = Sprite::create("PlayerHead.png");
        ret->addChild(ret->head);
        layer->addChild(ret, 100);
        return ret;
    }
    CC_SAFE_RELEASE(ret);
    return nullptr;
}

然后在你的场景中。h：

#include "Player.h"

在你的scene.cpp中：

auto player = Player::createPlayer(this);
addChild(player);
