Gamepad API
Allows you to use gamepads in javascript.
Quick start
<script src=".../gamepad.js" type="text/javascript"></script>var pad = Gamepads.get(0);In the game loop, you have to put the following command.
It will update the state of all the connected gamepads.
Gamepads.update();Properties
All the buttons/joysticks states are accessible like this:
Get a button state (replace X by a number). Return a value in the range [0..1]
pad.BUTTON_X;Get a joystick state (replace X by a number). Return a value in the range [-1..1]
pad.AXE_X;If the gamepad is known, you can access it with some user friendly names:
pad.A;
pad.B;
pad.X;
pad.Y;
pad.LEFT_SHOULDER_0;
pad.RIGHT_SHOULDER_0;
pad.LEFT_SHOULDER_1;
pad.RIGHT_SHOULDER_1;
pad.SELECT;
pad.START;
pad.LEFT_STICK_BUTTON;
pad.LEFT_STICK_BUTTON;
pad.UP;
pad.DOWN;
