Module: BubbleWrap::Motion

Defined in:
motion/motion/motion.rb,
motion/motion/motion.rb,
motion/motion/gyroscope.rb,
motion/motion/magnetometer.rb,
motion/motion/accelerometer.rb,
motion/motion/device_motion.rb

Overview

These module methods provide the main interface. It uses a shared manager (per Apple’s recommendation), and they all have a common set of supported methods:

available?
active?
repeat(opts)
once(opts)
every(time_interval, opts)

If you insist on using your own manager, or you want more than one BW::Motion::Whatever running at the same time, you’ll need to instantiate them yourself.

Examples:

if BW::Motion.accelerometer.available?
  BW::Motion.accelerometer.every(5) do |result|
    # see the README for the keys that are available in result.
  end
end

mgr = CMMotionManager.alloc.init
accel = BW::Motion::Accelerometer.new(mgr)
accel.once do |result_data|
end
# => BW::Motion::accelerometer.once do |result_data| ... end
