我目前为我的游戏提供了3个.cs文件，这些文件是Game1.cs（主文件），Player.cs和HUD.cs，目前我被困在一个循环中，Game1.cs类创建了一个新的HUD对象这将创建一个新的Game1对象等。下面的代码（使用XNA框架btw工作）。
HUD.cs
public class HUD
{
public Texture2D HUD_main, HUD_stamina, HUD_sBarDepleted, HUD_mana, HUD_health, HUD_money; //HUD TEXTURES
public int staminaWidth, manaWidth;
public SpriteFont HUDFont;
Player_Main pmain = new Player_Main();
Game1 gamecore = new Game1();
public HUD()
{
}
public void Update(GameTime gameTime)
{
staminaWidth = (int)pmain.pstats.currentStamina * 2; //Updating width of stamina bar based off of current stamina
pmain.pstats.staminaDisplay = Math.Round(pmain.pstats.currentStamina); //Separate variable for the stamina that shows on screen so it doesn't print decimals
manaWidth = (int)pmain.pstats.currentMana;
pmain.pstats.manaDisplay = Math.Round(pmain.pstats.currentMana);
}
public void LoadContent(ContentManager Content)
{
HUD_main = Content.Load<Texture2D>("HUD/HUD");
HUD_stamina = Content.Load<Texture2D>("HUD/staminabar");
HUDFont = Content.Load<SpriteFont>("HUD/HUDFont");
HUD_sBarDepleted = Content.Load<Texture2D>("HUD/bar_depleted");
HUD_mana = Content.Load<Texture2D>("HUD/manabar");
HUD_money = Content.Load<Texture2D>("HUD/moneybar");
HUD_health = Content.Load<Texture2D>("HUD/healthbar");
}
public void Draw(SpriteBatch spriteBatch)
{
spriteBatch.Draw(HUD_main, new Rectangle(0, 0, gamecore.viewportWidth, gamecore.viewportHeight), Color.White);
spriteBatch.Draw(HUD_sBarDepleted, new Rectangle(100, 0, 200, 20), new Rectangle(0, 0, 200, 20), Color.White);
spriteBatch.Draw(HUD_stamina, new Rectangle(100, 0, staminaWidth, 20), new Rectangle(0, 0, staminaWidth, 20), Color.White);
spriteBatch.Draw(HUD_sBarDepleted, new Rectangle(100, 20, 200, 20), new Rectangle(0, 0, 200, 20), Color.White);
spriteBatch.Draw(HUD_mana, new Rectangle(100, 20, manaWidth, 20), new Rectangle(0, 0, manaWidth, 20), Color.White);
spriteBatch.DrawString(HUDFont, pmain.pstats.staminaDisplay + "/" + pmain.pstats.maxStamina, new Vector2(175, 0), Color.White);
spriteBatch.DrawString(HUDFont, pmain.pstats.manaDisplay + "/" + pmain.pstats.maxMana, new Vector2(175, 20), Color.White);
spriteBatch.DrawString(HUDFont, "Ability: Cooldown", new Vector2(20, 40), Color.White);
spriteBatch.DrawString(HUDFont, "Teleport: " + pmain.pabilities.spellDisplay1 + "s", new Vector2(20, 60), Color.White);
}
}
Game1.cs
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
Player_Main player = new Player_Main();
HUD HUDmain = new HUD();
Texture2D grass1; //MAP TEXTURES
public int viewportWidth, viewportHeight;
//Classes
public Game1()
{
graphics = new GraphicsDeviceManager(this);
graphics.PreferredBackBufferWidth = 1280;
graphics.PreferredBackBufferHeight = 720;
Content.RootDirectory = "Content";
this.Window.Title = "Honour In Blood: Rise Against Rome";
}

grass1 = Content.Load<Texture2D>("grass1");
viewportHeight = GraphicsDevice.Viewport.Height;

player.LoadContent(Content);
HUDmain.LoadContent(Content);
}

GraphicsDevice.Clear(Color.CornflowerBlue);
KeyboardState KS = Keyboard.GetState();
spriteBatch.Begin(SpriteSortMode.Deferred, null, SamplerState.LinearWrap, null, null); // TILING
spriteBatch.Draw(grass1, new Rectangle(0, 0, viewportWidth, viewportHeight),new Rectangle(0,0,viewportWidth,viewportHeight), Color.White); //TILES BACKGROUND TO RESOLUTION OF WINDOW
player.Draw(spriteBatch);
HUDmain.Draw(spriteBatch);
spriteBatch.End();
base.Draw(gameTime);
}
}
如何在我的hud类中使用game1.cs中的变量而不必创建新对象？
答案 0 :(得分：0)
您帖子的第一条评论解释了您的StackOverflowException。
将对Game实例的引用传递给Hud组件，然后可以引用它及其属性。这就是Microsoft.Xna.Framework.GameComponent的设计方式。
在Hud.cs中：
Game1 gamecore;
public HUD(Game1 game)
{
gamecore = game;
}
在Game1.cs中
HUD HUDmain;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
graphics.PreferredBackBufferWidth = 1280;
graphics.PreferredBackBufferHeight = 720;
Content.RootDirectory = "Content";
this.Window.Title = "Honour In Blood: Rise Against Rome";
HUDmain = new HUD(this);
}
