Description
The Accelerometer class is used to access accelerometer data.
Examples
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
