Question

我正在寻找帮助在不同的类中创建精灵并提交cocos2d-x文件。我已经使用cocos2d-x网站上的代码来为sprite和其他帖子创建子类，这对我来说不起作用。我已经按照声纳系统教程为“鸟”精灵（在我的情况下为“播放器”）制作一个单独的类，并且在尝试通过Player类构造函数传递helloworld层时遇到错误，该构造函数接受参数一层。错误说：“'Player :: Player（const Player＆amp;）'：无法将参数1从'HelloWorld * const'转换为'const Player＆amp;' ApocalypseWorld c：\ cocosprojects \ apocalypseworld \ classes \ helloworldscene.cpp 39“

这是代码： 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下面得到一条红色的小红线：

player = new Player(this);

在HelloWorldScene.cpp文件的末尾

编辑代码：

Player.h：

QueueDStream

Player.cpp：

#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

然后在你的scene.h中：

#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;
}

在你的scene.cpp中：

#include "Player.h"

在不同的文件中创建一个sprite（在一个类中）
