I added some buttons to try to get it to work for phones... the buttons seem to work okay on a desktop but not on a phone :(

Original code changes: https://gist.github.com/darxx/b7e691a7f32041ee8be6d7a12e32f500

Splitted code to functions to make clear what they do.

keyCode - The problem with using keyCode is that non-English keyboards can produce different outputs and even keyboards with different layouts can produce inconsistent results.

And hope it works on mobile. If not.
Tell me more what phone are You using. @nateshields

ElusiveByte · 2019-06-01T08:22:32Z

hey man! just saw your video about this on your channel. Awesome! I'm planning to try it. I'll use your code, if I end up making any changes I'll post it on my repo and leave a comment here.
Btw, that problem you had with the keycode can be solved using mousetrapjs https://craig.is/killing/mice , if you don't mind to add an external library to your code. it's really lightweight though

thanx!

For some reason, no sound is playing for me on any of these scripts?

salamantos · 2020-01-29T19:22:29Z

Google Chrome 79.0.3945.130 gives the following error:

The AudioContext was not allowed to start. It must be resumed (or created) after a user gesture on the page.

haveboard · 2020-01-30T22:12:28Z

Added the start button to account for the "If you create your AudioContext on page load, you’ll have to call resume()" issue from

Suggestion: Use a repo with Github pages instead of Gist so that people could see the online version and try it very easily. Also much easier to contribute with PR.
