Description


The [[[Gyroscope]]] class is used to access gyroscope data.

Examples

Example

local gyroscope = Gyroscope.new()
gyroscope:start()

local angx = 0
local angy = 0
local angz = 0
local function onEnterFrame(event)
	local x, y, z = gyroscope:getRotationRate()
		
	angx = angx   x * event.deltaTime
	angy = angy   y * event.deltaTime
	angz = angz   z * event.deltaTime
		
	print(angx * 180 / math.pi, angy * 180 / math.pi, angz * 180 / math.pi)
end

stage:addEventListener(&quot;enterFrame&quot;, onEnterFrame)

Methods

Gyroscope.isAvailable - Gyroscope - does the gyroscope available?
Gyroscope.new - Creates new Gyroscope instance
Gyroscope:getRotationRate - Gyroscope - returns the rotation rate in radians per second
Gyroscope:start - Gyroscope - starts gyroscope updates
Gyroscope:stop - Gyroscope - stops gyroscope updates

Events

Constants
