Creating a sprite in a different file (in a class) - c++

Question

I am looking for help creating a sprite in a different class and file cocos2d-x. I have used the code from the cocos2d-x website for subclassing a sprite and other posts and It would not work for me. I have followed the sonar systems tutorial for making a separate class for a "bird" sprite ("Player" in my case) and am having trouble with an error when trying to pass the helloworld layer through the Player class constructor that takes a parameter of a layer. the error says: "'Player::Player(const Player &)': cannot convert argument 1 from 'HelloWorld *const ' to 'const Player &' ApocalypseWorld c:\cocosprojects\apocalypseworld\classes\helloworldscene.cpp 39"
here is the code:
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;
}
i get a little red squigly line under the t in:
player = new Player(this);
at the end of the HelloWorldScene.cpp file

Edited code:
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;
}
Then in your scene.h:
#include "Player.h"
And in your scene.cpp:
auto player = Player::createPlayer(this);
addChild(player);
