Unfortunately ToggleFullScreen() is a method from GraphicsDeviceManager (not from GraphicsDevice), and is not way call it from ScreenManager.Game (that I knows..)

Finally I found a way to resolve this, in ScreenManager I have created a new attribute:
public GraphicsDeviceManager graphics;

And change constructor this way:
public ScreenManager(Game game,GraphicsDeviceManager graphics) : base(game)
{
this.graphics = graphics;
}

To toggle full screen I call this in GameplayScreen: ScreenManager.graphics.ToggleFullScreen();
I don’t know if is the best way, but it works!

I am not looking at the code right now, but every gameplay screen should have a ScreenManager instance in it. You should be able to either find a GraphicsDevice on that ScreenManager somewhere, or a Game instance which has a GraphicsDevice on it. Something like ScreenManager.Game.GraphicsDevice.ToggleFullscreen();

Let me know if you still have issues and I’ll look at the code and give you a more accurate answer :)

I’m a little confused, i don’t know the exactly in which class I can introduce code so when you press a button changes between full-screen to window and vice versa.

If you look in this post’s comments, someone asked a similar question. I told them how they can have an Initialize method added to Screens where they can put code like this. Then you would modify the method that creates screens and have it call the Init function after assigning a ScreenManager to the class.

Alot of the game we are working on is nearly complete (or in advanced stages) and we are only now adding the game menu System. This is proving to me a total nightmare, with classes needed to be changed nearly everywhere (as we were accessing vars from the Game1 class). Anyway, we need access to the GraphicsDeviceManager, but the following code does not work:

if(graphics == null)
{
graphics = new GraphicsDeviceManager(ScreenManager.Game);
}

Any Ideas?

“public virtual void HandleSound(SoundManager sound) { }”

Sorry about that.

In “GameScreen” class i added :
public virtual void HandleCamera(FirstPersonCamera camera) { }

So in this way i can override the method in a similar way we do with HandleInput, but for audio, so that in the class you want to manage your audio you simply call:

public override void HandleSound(SoundManager sound)
{
sound.Play(”sound_file”);
}

Off course you need a “SoundManager” class that provides the “play” method, but normal tutorials for XNA audio usually show how to do it.

This worked for me :), but could be better ways.

if (ship.isActive)
{
// Draw all the active bullets on screen
for (int k = 0; k < GameConstants.NumBullets; k++)
{
if (bulletList[k].isActive)
{
Matrix bulletTransform =
Matrix.CreateTranslation(bulletList[k].position);
DrawModel(bulletModel, bulletTransform, bulletTransforms);

}
}

}
for the if (bulletList[k].isActive) part. but i have set it at the top with

Bullet[] bulletList = new Bullet[GameConstants.NumBullets];

the only real difference with my original game and this one is i put the i put the initialize stuff in the constructor and i didnt use UpdateInput method for the controls used the hanldeinput instead. If i take evrythhing to do with firing or bulletList out the game works fine, the badguys and the player are drawn onscreen so it is definatly to do with that.

Model bulletModel;
Matrix[] bulletTransforms;
Bullet[] bulletList = new Bullet[GameConstants.NumBullets];
is defined as follows. I hate to keep bothering you but this is the only place that get a useful answer to my questions.

Alright…check out comment #14 and 15 on this thread. You’ll find your answer!
