Question

I’m developing a game with AndEngine. I want to draw a sprite depending on current azimuth of my devices. How can I do it?
sorry for my bad English.

Answer 1

In a nutshell, you need to:

• have your class derived from BaseGameActivity and implement the IOrientationListener interface (i.e. overridding the onOrientationChanged() method)
• toward the end of the intialization process, invoke, the mEngine’s enableOrientationSensor()
• you’ll receive the orientation data from the OrientatonData parameter of the onOrientationChanged(), you’ll typically use the getRoll(), but depending on the complexity of your game’s gestures, the getPitch() and getYaw would give you the other directions.
• if needed you could alter the Orientation sensor’s settings as with other input sensors (e.g. make it refresh more or less frequently, with more or less precision etc.)

Tentatively, the AugmentedRealityHorizonExample source code shows you how this is all put together, although this example may be a bit more complicated than your needs, as it uses a BaseAugmentedRealityGameActivity.
