cocos2d-x – 将背景图像设置为适合任何屏幕

我正在使用cocos2d-x开发游戏.为了设置适合我的屏幕的背景图像,我使用了以下代码,但它拉伸图像请给出建议.

bool AppDelegate::applicationDidFinishLaunching() {
    CCDirector *pDirector = CCDirector::sharedDirector();
    pDirector ->setOpenGLView(CCEGLView::sharedOpenGLView());
    CCEGLView::sharedOpenGLView() ->setDesignResolutionSize(480, 320, kResolutionExactFit);
    pDirector ->setDisplayStats(false);
    pDirector ->setAnimationInterval(1.0 / 60);
    CCScene *pScene = SplashScene::scene();
    pDirector ->runWithScene(pScene);
    return true;
}

我通常做的是将图像缩放到屏幕尺寸比例.以下是一些帮助代码.

CCSprite * sprite = CCSprite::createWithSpriteFrameName(spriteName);
sprite->setScaleX((winSize.width / sprite->getContentSize().width) * scaleXFactor);
sprite->setScaleY((winSize.height / sprite->getContentSize().height) * scaleYFactor);

scaleXFactor和scaleYFactor是您想要的大小.如果您想要全屏,可以将其设置为1.
