cocos2dx实现3d拾取注意事项

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;

}
