Unswitch
Unswitch is a tiny (400b) event handler for Switch controllers on the web based on the Gamepad API. Attach callbacks to button presses (up & down) and the joystick!
Install
$ npm install --save unswitch
Setup
Connecting a Switch controller is easy: pair it with bluetooth and you're ready to go! This library doesn't listen to connected or disconnected events but in some cases it might be useful. Here's how you can listen to these events:
window.addEventListener("gamepadconnected", ({ gamepad }) => {});
window.addEventListener("gamepaddisconnected", ({ gamepad }) => {});
Usage
// Import the library import Unswitch from 'unswitch'; // Create the listener const unswitch = new Unswitch({ b: (pressed) => {}, a: (pressed) => {}, y: (pressed) => {}, x: (pressed) => {}, l: (pressed) => {}, r: (pressed) => {}, axes: (position) => {}, }); function render() { // Check for button stateupdates unswitch.update(); requestAnimationFrame(render); } render();
Calling unswitch.update() will check every button for a change in state. If a callback is provided the new state is passed along. The axis works in the same way, but instead of a boolean it will return a number from 0 to 8. Number 0 to 7 are for the joystick positions going clockwise, number 8 is used as default (center).
Buttons are mapped based on a single controller positioned horizontally.
