Ezzel mit csináljak?

Találtam egy ilyen JavaScriptet. Ebben mit hogy kell kitölteni, hogy tudjak a készülő játékomban menteni?

A script:

var player = {

name:"",

level:0,

gold: 190,// CHANGE BACK TO 0 AFTER TESTING

artifact: 0,

weaponId:0,

weaponLevel:0,

spellId:0,

spellLevel:0,

goldPerClick:5,

goldPerSec:0,

currentTrainer:0,

};

SAVE STATE

/* SETUP A SAVE STATE */

function save() {

// TRY TO SAVE THE GAME

try {

localStorage.setItem('copperSave',JSON.stringify(player));

}catch(err) {

console.log('Cannot access localStorage - browser may be old or storage may be corrupt')

}

console.log('Game saved successfully');

}// FUNCTION: SAVE GAME

LOAD STATE

/* LOAD PREVIOUS game */

function loadGame() {

var gameLoad = JSON.parse(localStorage.getItem("copperSave"));

player= gameLoad.player;

console.log(player); // this shows the starting vars NOT the saved var from getItem!

}

SOME MISC VARS TO HELP DEBUG

initGame();

var answer = confirm('Continue from previous saves?\nWarning, "Cancel" creates a new game wiping previous saves');

if ( answer ) {

loadGame();

}

console.log('here after load query');

// GAME LOOP FOLLOWS BELOW....
