cocos2dx实现拾取注意事项

标签：

用的是cocos2dx 3.x，如果是真机测试，glview = cocos2d::GLViewImpl::createWithRect(...)和glview->setDesignResolutionSize(...)都得传设备的分辨率，才能使拾取的结果正确。

bool AppDelegate::applicationDidFinishLaunching()

{

    // initialize director

    auto director = Director::getInstance();

    auto glview = director->getOpenGLView();

#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32||CC_TARGET_PLATFORM == CC_PLATFORM_MAC)

    auto size = CCSize(1136,640);

#else

    auto size = glview->getVisibleSize();

#endif

    if(!glview) {

        glview = cocos2d::GLViewImpl::createWithRect("HelloWorld", Rect(0,0,size.width,size.height));//Rect(0,0,900,640));

        director->setOpenGLView(glview);

    }

    // set FPS. the default value is 1.0/60 if you don‘t call this

    director->setAnimationInterval(1.0 / 60);

    glview->setDesignResolutionSize(size.width,

                                    size.height,

                                    kResolutionShowAll);

    director->runWithScene(HelloWorld::scene());

    return true;

}
