Well lately i got interested in creating JS games. (not an area i have experience with but it interests me).
i know there are several gaming engines for JS out there but i dont really want to create a game. rather i am curious on how things work / how can i create one.
I have several questions:
Anyone with suggestions on where can I read about it? Prerequisite (what knowledge is needed).
I tried making a small game of something walking in a rectangular. By binding keyup to the window and checking the event.which to get the key that was pressed. I realized that if i clicked on 2 buttons same time only 1 of them is being registered. how can i overcome that?
$(window).keyup(function(event){
globalEvent = event.which;
});
To directly answer your second question.
Here is one way:
var keyPressed = {};
$(window).keydown(function(e) {
keyPressed[e.which] = true;
}).keyup(function(e) {
keyPressed[e.which] = false;
});
Now you can use keyPressed whenever you want to determine if a key is down:
// wherever
var key1 = 65, key2 = 66; // A and B
if (keyPressed[key1] && keyPressed[key2]) {
// A and B are both being pressed.
}
