Question

Create a base data model that can be duplicated and modified as needed

In my two-player game, both players start with similar data that evolves as the game progresses.

I believe I need to create a constructor object that can be duplicated and modified, while also being in JSON format for easy ajax sending.

Is there a design pattern that could assist me? I would rather avoid using a database since I only require the data for a single instance of the game.

Currently, this is the structure I am using for one player:

player = {
    "active" : true,
    "room" : openRoom,
    "id" : playerID,
    "name": username,
    "hp" : 5,
    "units" : {
        1 : {
            "id" : 1,
            "hp" : 3,
            "row" : 1,
            "square" : 1
        },
        2 : {
            "id" : 2,
            "hp" : 4,
            "row" : 2,
            "square" : 1
        },
        3 : {
            "id" : 3,
            "hp" : 5,
            "row" : 3,
            "square" : 1
        }
    }
};

When it comes to object instantiation and initialization, there are numerous design patterns to consider. In your case, where inheritance or "property sharing" techniques are not necessary, a straightforward function that creates a new object as a constructor should suffice. You can even utilize object literals for simplicity.

Here is an example of two constructor functions, each accepting certain parameters:

function createPlayer(id, name, units) {
    return {
        "active" : true,
        "room": openRoom,
        "id" : id,
        "name": name,
        "hp" : 5,
        "units" : units
    };
}
var uniqueId = 1;
function createUnit(row) {
    return {
        "id" : uniqueId++,
        "hp" : 3,
        "row" : row,
        "square" : 1
    };
}
var player = makePlayer(playerId, username, [makeUnit(2), makeUnit(4), makeUnit(3)]);
var jsonString = JSON.stringify(player);

You can find all the necessary information in the "Using an object constructor" section on this website. It provides an example using a Person object, which I believe can be directly applied to your current project.

To duplicate a JSON object, you can utilize JQuery for a simpler approach:

copy1 = $.extend({}, original, {key:"value"});
copy2 = $.extend({}, original, {key:"value"});

If JQuery is not an option, you can achieve the same using JSON methods:

var copy1 = JSON.parse(JSON.stringify(original));
var copy2 = JSON.parse(JSON.stringify(original));
copy1.key = "value";
copy2.key = "value";
