Android hardware and Adobe AIR cont
I asked in a previous post if it was possible to access native API from AIR. LadaRaider answered that it was not, but linked me to a site with a hack around it. Today I noticed a default AIR application in Flash that uses the accelerometer on an Android device to move a ball arou开发者_如何学JAVAnd. Can anyone explain this?
import flash.events.Event;
var accelX:Number;
var accelY:Number;
var fl_Accelerometer:Accelerometer = new Accelerometer();
fl_Accelerometer.addEventListener(AccelerometerEvent.UPDATE, fl_AccelerometerUpdateHandler);
function fl_AccelerometerUpdateHandler(event:AccelerometerEvent):void
{
accelX = event.accelerationX;
accelY = event.accelerationY;
}
ball.addEventListener(Event.ENTER_FRAME, moveBall);
function moveBall(evt:Event)
{
ball.x -= accelX*30;
ball.y += accelY*30;
if(ball.x > (480-ball.width/2))
{
ball.x = 480-ball.width/2;
}
if(ball.x < (0+ball.width/2))
{
ball.x = 0+ball.width/2;
}
if(ball.y > (800-ball.width/2))
{
ball.y = 800-ball.width/2;
}
if(ball.y < (0+ball.width/2))
{
ball.y = 0+ball.width/2;
}
}
Where is this AccelerometerEvent.UPDATE
coming from?
Thanks,
flash.sensors
package.
Here is an example tutorial for accelerometer in AS3.
