Changing enum in a different class for screen
- by user2434321
I'm trying to make a start menu for my game and my code uses Enum's to moniter the screen state.
Now i want to change the screenstate declared in the main class, in my Background class
Screen screen = new Screen();
is declared in the Game1 class
Background(ref screen);
This is in the update method for the Background Class
KeyboardState keystate = Keyboard.GetState();
switch (screen)
{
case Screen.Start:
if (isPressed && keystate.IsKeyUp(Keys.Up) && keystate.IsKeyUp(Keys.Down) && keystate.IsKeyUp(Keys.Enter))
{
isPressed = false;
}
if (keystate.IsKeyDown(Keys.Down) && isPressed != true)
{
if (menuState == MenuState.Options)
menuState = MenuState.Credits;
if (menuState == MenuState.Play)
menuState = MenuState.Options;
isPressed = true;
}
if (keystate.IsKeyDown(Keys.Up) && isPressed != true)
{
if (menuState == MenuState.Options)
menuState = MenuState.Play;
if (menuState == MenuState.Credits)
menuState = MenuState.Options;
isPressed = true;
}
switch (menuState)
{
case MenuState.Play:
arrowRect.X = 450;
arrowRect.Y = 220;
if (keystate.IsKeyDown(Keys.Enter) && isPressed != true)
screen = Screen.Play;
break;
case MenuState.Options:
arrowRect.X = 419;
arrowRect.Y = 340;
if (keystate.IsKeyDown(Keys.Enter) && isPressed != true)
screen = Screen.Options;
break;
case MenuState.Credits:
arrowRect.X = 425;
arrowRect.Y = 460;
if (keystate.IsKeyDown(Keys.Enter) && isPressed != true)
screen = Screen.Credits;
break;
}
break;
}
}
For some reason when I play this and I hit the enter button the Background class's screen is changed but the main class's screen isn't how can i change this?
EDIT 1*
class Background
{
private Texture2D background;
private Rectangle backgroundRect;
private Texture2D arrow;
private Rectangle arrowRect;
private Screen screen;
private MenuState menuState;
private bool isPressed = false;
public Screen getScreenState(ref Screen screen)
{
this.screen = screen;
return this.screen;
}
public Background(ref Screen screen)
{
this.screen = screen;
}
public void Update()
{
KeyboardState keystate = Keyboard.GetState();
switch (screen)
{
case Screen.Start:
if (isPressed && keystate.IsKeyUp(Keys.Up) && keystate.IsKeyUp(Keys.Down) && keystate.IsKeyUp(Keys.Enter))
{
isPressed = false;
}
if (keystate.IsKeyDown(Keys.Down) && isPressed != true)
{
if (menuState == MenuState.Options)
menuState = MenuState.Credits;
if (menuState == MenuState.Play)
menuState = MenuState.Options;
isPressed = true;
}
if (keystate.IsKeyDown(Keys.Up) && isPressed != true)
{
if (menuState == MenuState.Options)
menuState = MenuState.Play;
if (menuState == MenuState.Credits)
menuState = MenuState.Options;
isPressed = true;
}
switch (menuState)
{
case MenuState.Play:
arrowRect.X = 450;
arrowRect.Y = 220;
if (keystate.IsKeyDown(Keys.Enter) && isPressed != true)
screen = Screen.Play;
break;
case MenuState.Options:
arrowRect.X = 419;
arrowRect.Y = 340;
if (keystate.IsKeyDown(Keys.Enter) && isPressed != true)
screen = Screen.Options;
break;
case MenuState.Credits:
arrowRect.X = 425;
arrowRect.Y = 460;
if (keystate.IsKeyDown(Keys.Enter) && isPressed != true)
screen = Screen.Credits;
break;
}
break;
case Screen.Pause:
break;
case Screen.Over:
break;
}
}
public void LoadStartContent(ContentManager Content, GraphicsDeviceManager graphics)
{
background = Content.Load<Texture2D>("startBackground");
arrow = Content.Load<Texture2D>("arrow");
backgroundRect = new Rectangle(0, 0, graphics.GraphicsDevice.Viewport.Width, graphics.GraphicsDevice.Viewport.Height);
arrowRect = new Rectangle(450, 225, arrow.Width, arrow.Height);
screen = Screen.Start;
}
public void LoadPlayContent(ContentManager Content, GraphicsDeviceManager graphics)
{
background = Content.Load<Texture2D>("Background");
backgroundRect = new Rectangle(0, 0, graphics.GraphicsDevice.Viewport.Width, graphics.GraphicsDevice.Viewport.Height);
screen = Screen.Play;
}
public void LoadOverContent(ContentManager Content, GraphicsDeviceManager graphics)
{
}
public void Draw(SpriteBatch spritebatch)
{
if (screen == Screen.Start)
{
spritebatch.Draw(background, backgroundRect, Color.White);
spritebatch.Draw(arrow, arrowRect, Color.White);
}
else
spritebatch.Draw(background, backgroundRect, Color.White);
}
}
Thats my background class!
