MKJS Controller Support
I implemented controller support for MKJS - Mario Kart in the browser.
I saw an interesting gif of Krunker.io (the web game) being played on an Xbox Series X the other day.
My first thought was, "wow, that's cool, the PlayStation doesn't have WebGL support". I then remembered the time I tried to get MKJS working on my PlayStation 4 a few years ago - but, since there wasn't any support for accelerated graphics within the integrated browser, it didn't work.
I then just went down a train of thoughts - stuff like, "wow it must suck having to use a mouse and keyboard on a console", "I wonder if MKJS would work on an Xbox", etc. until I arrived at "hey maybe I should get controller support working for MKJS".
So that's what I did.
The first thing I did was to get the button layout right. It uses the same layout as the original Mario Kart DS - so controls are basically 1:1. The only exception to this is the turning, which is now completely analog.
I also added rumble support... but trying to demonstrate that is hard, so you'll just have to imagine it. Rumble support is basic - it happens on specific events (kart collisions, drifting, whenever you spin out after hitting an item) and it's all tuned manually, so it's not perfect. It does a great job at making the game feel a lot more polished though.
Eventually I'll PR this into the main MKJS repo, but it needs some more testing. If you're really impatient, you can test it here right now.
