Question

当我从“Cocos2d-x初学者指南”一书中做一个教程（空气曲棍球）时，我在Cocos2d-x（2.1.5）中收到这些消息。

我已经检查了Xcode中的所有“#include”，BuildPhases等，并在“编译源代码”（大约250个文件）中执行了“验证设置”并筛选了互联网，并希望任何人对此进行查看。我还没有在.cpp文件中引用它们。

顺便说一下，本书中的Cocos2d-x版本与我使用的版本不一样，我查看了图书网站并从作者那里找到了这个版本：the Authors comment on the releases for the tutorial(s)

这是我第一次尝试非Objective-C＆amp;的cocos2d-X。

GameLayer.h：

#ifndef __GAMELAYER_H__
#define __GAMELAYER_H__

#define GOAL_WIDTH 400

#include "cocos2d.h"
#include "GameSprite.h"

using namespace cocos2d;

class GameLayer : public cocos2d::CCLayer {

GameSprite  *_player1;
GameSprite  *_player2;
GameSprite  *_ball;

CCArray     *_players;
CCLabelTTF  *_player1ScoreLabel;
CCLabelTTF  *_player2ScoreLabel;

CCSize      _screenSize;

int _player1Score;
int _player2Score;

void playerScore (int player);

public:

~GameLayer();

virtual bool init();

static CCScene *scene();

CREATE_FUNC(GameLayer);

virtual void ccTouchesBegan(CCSet* pTouches, CCEvent* event);
virtual void ccTouchesMoved(CCSet* pTouches, CCEvent* event);
virtual void ccTouchesEnded(CCSet* pTouches, CCEvent* event);

void update (float dt);

};

#endif // __GAMELAYER_H__

Answer 1

您没有在GameLayer.ccp中实现这些功能。在本教程之后，它将教你如何实现它们。

Cocos2d-x - clang：错误：链接器命令失败，退出代码为1（使用-v查看调用）
