Implementing controls using the Gamepad API - Game development
having a gamepad connected — click the gamepad icon in the top right corner of the screen. it will launch the game in the super turbo mode and you'll be able to control the fridge with the keyboard: a and d for turning the turret left and right, w for shooting and arrow keys for movement. implementation there are two important events to use along with the gamepad api — gamepadconnected and gamepaddisconnected. the first one is fired when the browser detects the connection of a new gamepad while the second one is fired when a gamepad is disconnected (either physically by the user or due to inactivity.) in the demo, the gamepadapi object is used to store everything related to the api: var gamepadapi = { controller: {}, turbo: false, connect: function() {}, disconnect: function() {}, update: f...
...'rb','power','a','b','x','y', ], this can be different for other types of gamepads like the ps3 controller (or a no-name, generic one), so you have to be careful and not just assume the button you're expecting will be the same button you'll actually get. next, we set up two event listeners to get the data: window.addeventlistener("gamepadconnected", gamepadapi.connect); window.addeventlistener("gamepaddisconnected", gamepadapi.disconnect); due to security policy, you have to interact with the controller first while the page is visible for the event to fire. if the api worked without any interaction from the user it could be used to fingerprint them without their knowledge. both functions are fairly simple: connect: function(evt) { gamepadapi.controller = evt.gamepad; gamepadapi.turbo = true; conso...
...type is now an enumerable object instead of a string: enum gamepadmappingtype { "", "standard" }; this enum defines the set of known mappings for a gamepad. for now, there's only the standard layout available, but new ones may appear in the future. if the layout is unknown, it is set to an empty string. events there were more events available in the spec than just gamepadconnected and gamepaddisconnected available, but they were removed from the specification as they were thought to not be very useful. the discussion is still ongoing as to whether they should be put back, and in what form. summary the gamepad api is very easy to develop with. now it's easier than ever to deliver a console-like experience to the browser without the need for any plugins. you can play the full version of the hungr...
