I am trying to build a small, online card game with NodeJS. Having C# and
javascript experience, I am having way more trouble than I expected.
Using node-static, I set up an http server (server.js) that successfully
serves client.html and any requested assets.
I am starting to build the basics of the card game using the CraftyJS
library in client.js (running on the client.html page).
Using Socket.io, I can successfully send information from server.js to my
client.js file.
My next step was to generate an array of cards in server.js, splice one out
randomly, and send it to client.js. My hope was:
var deck = new Array();
deck.push(new Array("card1 info", "more info"));
deck.push(new Array("card 2 info", "more info"));
deck.push(new Array("card 3 info", "more info"));
function drawCard(){
return deck.splice(1,1);
}
I've spent the whole day reading, but I can't find a clear concise answer.
Question 1: Why doesn't this work? The V8 compiler sees arrays as string
values? This is not the javascript I know, is there a tutorial for this new
way of dealing with arrays?
After more reading, I got it working a this way:
var deck = [];
deck[0] = {info:"test", moreInfo:"test"};
deck[1] = {info:"test", moreInfo:"test"};
deck[2] = {info:"test", moreInfo:"test"};
However:
console.log(deck[0]) yields {info: 'test', moreInfo:'test'}
console.log(deck.splice(0,1)) yields *[*{info: 'test', moreInfo:'test'}*]*
*
*
Question 2: Why does splice return the square brackets, but calling the
value directly does not?
Any answers or additional links are really appreciated. When I search for
javascript help, I end up on HTML javascript pages, which obviously doesn't
work as I expect.
