Base Code, libraries

I’m completely new to this so sorry if this post is annoying but I think I have to write a post about any core libraries I’m going to use? So I guess This is where I have to do that.


I’ll be using jquery-1.10.2 (I’m assuming you don’t want me to paste all the code in there)

key_status.js Contents:

$(function() {
window.keydown = {};

function keyName(event) {
return jQuery.hotkeys.specialKeys[event.which] ||
String.fromCharCode(event.which).toLowerCase();
}

$(document).bind(“keydown”, function(event) {
keydown[keyName(event)] = true;
});

$(document).bind(“keyup”, function(event) {
keydown[keyName(event)] = false;
});
});

jquery.hotkeys.js alone with it’s COMPONENT JSON Contents:

Sorry about the format

But I guess now it’s okay that I use them?

Please let me know if I horribly embarrassed myself.

 

And also may use Box2dWeb-2.1.a.3.min

I think this is fine. With the full “rolling toolboxes” I’ve seen others swinging around here, no one should complain about a couple of utility functions like these.

I’ll also may be using Box2dWeb-2.1.a.3.min hopefully that won’t be a problem either.
