The principle of the helmet is very simple, roughly the use of two lenses, shorten the focal length of the eye, the two eyes can be seen into one another to create a dual-screen 3D effect.So I began to imagine: since the 3D effect, in order to achieve a more immersive experience, why not the head of the movement also mapped to the virtual world? With this idea in mind, we have made the following attempt:The head data (such as rotation angle, pitch angle, etc.) with the

switch the scenario, instead of passing a function pointer in this way. In this case, the home scene and sub-scenario should reference the header file to instantiate the other party, in violation of the low coupling principle.
This is defined in the header file of the sub-scenario:
Public: std::function
We can register the callback function as follows when switching from the main scenario to the sub-scenario:

At the beginning of the release, although it gives everyone a bright feeling, but no one believes that gyroscopes can become the next standard for smartphones. Nowadays the gyroscope has already surpassed the meaning that enhances the game experience before. Gyro inertial navigation, gyroscope combined with optical stab

(In fact, the app simply no longer receives touch class events, other types of events such as acceler

Everything Flash developers need to know to create native Android and iPhone apps
This wrox guide shows Flash developers how to create native applications for Android and iPhone mobile devices using flash. packed with practical examples, it shows how to build a variety of apps and integrate them with core mobile services such as accelerometer, GPS, phot
Accelerometer
The accelerometer API is used to obtain data from the gravitational acceleration sensor, which is used to develop programs such as games.
if (am != null) am.Stop(); am = new Accelerometer(); am.ReadingChanged += new EventHandler try//因为启动时,如果出错会抛出异常,所以要用try块来处理。 { am.Start();//开始获取数据 } catch(AccelerometerFailedException e) { } am.Stop()

Other event passes may be slightly different from touch event passing through a variety of application objects.There are many types of events that can be passed in an iOS app. The most common events are listed in the following table:Most of these event types are passed through the application's main run loop, but some are not. For example: The accelerometer event is passed directly to the application of the specified
