XInput/Xbox 360 controller support for OpenFL on Windows. For the Windows target, given that the user has a 360 controller, here are the key benefits over the OpenFL JoystickEvent:

• Individual data for each trigger. Under DirectInput you get both triggers as a single bipolar axis (useless)
• Individual control over each vibrator. Allows for a wide range of haptic feedback.
• Controller hotswapping. Your game will happily run with or without a controller connected. A controller may get dropped and reconnected to no further detriment to your game.
• Simplified API. The XBox360Controller class is a one-stop, direct way to get at the game controller.

Usage:

##Initialization Create a new controller with a unique controller ID (zero indexed) You should also check if it's connected.

controller = new XBox360Controller(0);
controller.isConnected();

You can check if the controller is connected without creating an instance

XBox360Controller.isControllerConnected(0);

##Deadzones Set individual stick deadzones with a scalar. You can also set the deadzone precisely with an int within 32767

controller.leftStick.deadZoneNorm = 0.2; 
controller.rightStick.deadZoneNorm = 0.2;

Both triggers share the same deadzone setting, an int from 0 to 255

controller.triggerDeadzone = 30;

##Game update During game updates, call poll() to update the controller state.

controller.poll();

Poll controller for buttons and values. Buttons are booleans, triggers are ints between 0 and 255, sticks are slightly more involved

controller.leftStick.xRaw; //The raw -32767 to 32767 range
controller.leftStick.xNorm; //The range normalized to a bipolar 0-1 scalar, pre-adjusted by the deadzone

##Rumble The 360 controller has two vibrators. In my experience the left vibrator is "coarser" while the right vibrator is "finer".

if (controller.leftBumper.isDown) {
	controller.vibrationLeftNorm = controller.leftTriggerNorm;
}else {
	controller.vibrationLeft = 0; //Vibrations remain set so you have to manually turn them off
}
if (controller.rightBumper.isDown) {
	controller.vibrationRightNorm = controller.rightTriggerNorm;
}else {
	controller.vibrationRight = 0; 
}

The vibrators have quite a nice dynamic range; You can fine control it up to 65535. I've seen games use this to "drive" the vibrators with audio signals. Quite cool.

##Events XBox360Controller buttons are represented with Xbox360Button objects. To receive callbacks when a button is pressed or released, do the following:

function onButtonChange(btn:Xbox360Button):Void 
{
	trace(btn.buttonType, btn.controller.id, btn.isDown);
}

controller.a.onPressed = onButtonChange;
controller.a.onReleased = onButtonChange;

Xbox360Button.buttonType is one of the types found in Xbox360ButtonType.

For convenience, Xbox360Controller has a method for setting listeners on every button.

controller.setButtonListeners(onButtonDown, onButtonUp);
//to clear the listeners, call again with no arguments, or use clearButtonListeners()
