Description

The Accelerometer class is used to access accelerometer data.

Example

local filter = 0.03
local fx, fy, fz = 0, 0, 0
--create instance
local accelerometer = Accelerometer.new()
--start receiving data
accelerometer:start()

function onEnterFrame(event)
	---get values for example on each enter frame event
	local x, y, z = accelerometer:getAcceleration()
	fx = x * filter + fx * (1 - filter)
	fy = y * filter + fy * (1 - filter)
	fz = z * filter + fz * (1 - filter)
	print("Y: "..math.floor(fy*90*-1))
	print("X: "..math.floor(fx*90*-1))
	print("Z: "..math.floor(fz*90*-1))
end
stage:addEventListener("enterFrame",onEnterFrame,self)

Methods

Accelerometer.isAvailable is the accelerometer available?
Accelerometer.new creates a new Accelerometer instance

Accelerometer:getAcceleration returns the 3-axis acceleration measured by the accelerometer
Accelerometer:start starts accelerometer updates
Accelerometer:stop stops accelerometer updates
