As the title suggests, in my code I use the following codes:
- Left: 37
- Up: 38
- Right: 39
- Down: 40
And check for those key codes to determine my action. My question is, do those always remain the same? If I were to use a DVORAK keyboard, or a non-English keyboard, would those key codes remain the same?
Along the same line, is there a preferred method for detecting those keystrokes?
Currently, I do it as follows:
var Key = {
_pressed: {},
LEFT: 37,
UP: 38,
RIGHT: 39,
DOWN: 40,
isDown: function (keyCode) {
return this._pressed[keyCode];
},
onKeydown: function (event) {
this._pressed[event.keyCode] = true;
if (Key.isDown(Key.UP))
//do up action
else if (Key.isDown(Key.DOWN)) {
//do down action
}
delete this._pressed[event.keyCode];
}
};
