Reading and writing a custom class properties from outside

by Arden · in Torque X 2D · 09/22/2010 (7:05 pm) · 4 replies

Hey guys, I have a somewhat rethoric question about classes.
I'd like to create a class that contains all of the game state stuff. For instance:

public class GameState
    {
        int _numberOfLivesRemaining = 3;
        int _score = 0;


        public int NumberOfLivesRemaining
        {
            get { return _numberOfLivesRemaining; }
            set { _numberOfLivesRemaining = value; }
        }

        public int playerScore
        {
            get { return _score; }
            set { _score = value; }
        }

        public int playerGold
        {
            get { return _score; }
            set { _score = value; }
        }

        public T2DSceneObject _currentSpawner
        {
            get { return _currentSpawner; }
            set { _currentSpawner = value; }
        }

My question is, once this class is saved and part of the solution as a CS file, how would I go about consulting its public properties and updating them from other components and methods?

I've tried using namespace.class.method syntax to no avail.

In the new CS file give it a new namespace name

namespace NewNAME
{
    //Class code here
}

Now you should be able to call it with using

using NewName;

I have never tried this, but this is my understanding of how it works from viewing the source code of other files being used.

Let me know if it works!

Ok so here's what I did:

- I changed the namespace for my Gamestate class to GlobalClass.
- I then added 'using' in my game.cs file.
- Then, to attempt to create a class instance I could use in my game.cs, I then added:

#region Private, protected, internal fields
        GameState _gameState;
then, in public void Startgame() I added:
_gameState = new GameState();

So far so good.
Finally I added to public properties:
public GameState GameStateCurrent
{
    get { return _gameState; }
}

I now have an object based on a class, but I'm still stomped as to how I manipulate it and look and update its properties. Since the object is now globally known as GameStateCurrent, I figure I should be doing something like:

GameStateCurrent.playerScore=100;

but that doesn't work, as I'm getting "A namespace does not directly contain members such as fields or methods"

... Any suggestions?

Using the singleton method should work.

You'll want to call a method like this: 
GameState.Instance.playerScore += 100;

Setting up a singleton for that class should look like this 

public static GameState Instance
{
get
{
if (_instance == null)
_instance = new GameState();
return _instance;
}
}

private static GameState _instance;

The above code should be added to your GameState class.

This is great Will. It works! This will be really useful!
My thanks :)
