title: Creating vertical camera rotation touch control for mobile using A-Frame
body: <p>I'm developing a lot these days with A-Frame, but more specifically targeting mobile. One thing I noticed is that the touch controls for mobile only allow for horizontal camera rotation movement(left/right). I realize the gyroscope is to be a huge factor in camera rotation movement, but it would be nice to have full control of the camera using touch (horizontal and vertical). The default setting for the camera only allows horizontal rotation movement. I haven't seen were to implement certain properties to the camera entity, or to write some script. Is there a simple boolean property I can set on an entity, or am I completely off base?</p>
