bool AppDelegate::applicationDidFinishLaunching() 中修改为

Vec2 frameSize(1500, 300);  Vec2 resolutionSize(960,640); bool AppDelegate::applicationDidFinishLaunching() {    // initialize director    auto director = Director::getInstance();    auto glview = director->getOpenGLView();    if(!glview) {        glview = GLViewImpl::create("My Game"); glview->setFrameSize(frameSize.x, frameSize.y);          director->setOpenGLView(glview);float currentAspectRatio = director->getWinSize().width/director->getWinSize().height;  float originalAspectRatio = resolutionSize.x/resolutionSize.y;  if(currentAspectRatio>originalAspectRatio)//采用根据宽度自适应  {  glview->setDesignResolutionSize(resolutionSize.x,resolutionSize.y,kResolutionFixedHeight );  }  if(currentAspectRatio<=originalAspectRatio)// 采用根据长度自适应  {  glview->setDesignResolutionSize(resolutionSize.x,resolutionSize.y, kResolutionFixedWidth );  }      }    // turn on display FPS    director->setDisplayStats(true);    // set FPS. the default value is 1.0/60 if you don't call this    director->setAnimationInterval(1.0 / 60);    // create a scene. it's an autorelease object    auto scene = HelloWorld::createScene();    // run    director->runWithScene(scene);    return true;}

修改CCGLView.h文件

添加成员

public:Size getResolutionSize();float getCurrentAndOrignalRatioX();float getCurrentAndOrignalRatioY();Vec2 MyPoint(cocos2d::Vec2& pos);

修改CCGLView.cpp文件

添加实现

float GLView::getCurrentAndOrignalRatioX(){return m_currentAndOrignalRatioX;}float GLView::getCurrentAndOrignalRatioY(){return m_currentAndOrignalRatioY;}Size GLView::getResolutionSize(){return m_resolutionSize;}cocos2d::Vec2 GLView::MyPoint( cocos2d::Vec2& pos ){Vec2 _point = pos-=m_resolutionSize/2;  Vec2 _offset;  switch (this->getResolutionPolicy())  {  case ResolutionPolicy::FIXED_HEIGHT:  {  _offset = Vec2 (_point.x/getCurrentAndOrignalRatioY()*getCurrentAndOrignalRatioX() ,_point.y );  break;  }  case ResolutionPolicy::FIXED_WIDTH:  {  _offset =Vec2 (_point.x ,_point.y/getCurrentAndOrignalRatioX()*getCurrentAndOrignalRatioY() );   break;  }  default:  break;  }  return (Vec2(m_resolutionSize/2) +_offset );  }

修改函数定义

void GLView::setDesignResolutionSize(float width, float height, ResolutionPolicy resolutionPolicy){    CCASSERT(resolutionPolicy != ResolutionPolicy::UNKNOWN, "should set resolutionPolicy");        if (width == 0.0f || height == 0.0f)    {        return;    }    _designResolutionSize.setSize(width, height);m_resolutionSize = _designResolutionSize;    _resolutionPolicy = resolutionPolicy;        updateDesignResolutionSize(); }

void GLView::updateDesignResolutionSize(){    if (_screenSize.width > 0 && _screenSize.height > 0        && _designResolutionSize.width > 0 && _designResolutionSize.height > 0)    {        m_currentAndOrignalRatioX =  _scaleX = (float)_screenSize.width / _designResolutionSize.width;        m_currentAndOrignalRatioY = _scaleY = (float)_screenSize.height / _designResolutionSize.height;                if (_resolutionPolicy == ResolutionPolicy::NO_BORDER)        {            _scaleX = _scaleY = MAX(_scaleX, _scaleY);        }                else if (_resolutionPolicy == ResolutionPolicy::SHOW_ALL)        {            _scaleX = _scaleY = MIN(_scaleX, _scaleY);        }                else if ( _resolutionPolicy == ResolutionPolicy::FIXED_HEIGHT) {            _scaleX = _scaleY;            _designResolutionSize.width = ceilf(_screenSize.width/_scaleX);        }                else if ( _resolutionPolicy == ResolutionPolicy::FIXED_WIDTH) {            _scaleY = _scaleX;            _designResolutionSize.height = ceilf(_screenSize.height/_scaleY);        }                // calculate the rect of viewport        float viewPortW = _designResolutionSize.width * _scaleX;        float viewPortH = _designResolutionSize.height * _scaleY;                _viewPortRect.setRect((_screenSize.width - viewPortW) / 2, (_screenSize.height - viewPortH) / 2, viewPortW, viewPortH);                // reset director's member variables to fit visible rect        auto director = Director::getInstance();        director->_winSizeInPoints = getDesignResolutionSize();        director->createStatsLabel();        director->setGLDefaultValues();    }}
