第一次在这里发帖，我知道我可能会因为我的编码而受到抨击，但我是12年级的学生并且为我的软件专业自学这门语言，我今天才开始理解课程，所以我我试着用这个想法重新开始我的游戏，游戏还远未完成。抱歉很长的代码，但我真的无法弄清楚什么是错的，在game1.cs中只有player.LoadContent（内容），player.Update（gameTime）和player.Draw（spriteBatch），玩家正在Player_Main类的Object。

这是调用堆栈：
HonourInBlood.exe！HonourInBlood.Player_Sprite.Player_Sprite（）第45行+ 0xffffffe6字节C＃ HonourInBlood.exe！HonourInBlood.Player_Main.Player_Main（）第14行+ 0x15字节C＃ HonourInBlood.exe！HonourInBlood.Player_Sprite.Player_Sprite（）第45行+ 0x15字节C＃ HonourInBlood.exe！HonourInBlood.Player_Main.Player_Main（）第14行+ 0x15字节C＃ HonourInBlood.exe！HonourInBlood.Player_Sprite.Player_Sprite（）第45行+ 0x15字节C＃ HonourInBlood.exe！HonourInBlood.Player_Main.Player_Main（）第14行+ 0x15字节C＃ HonourInBlood.exe！HonourInBlood.Player_Sprite.Player_Sprite（）第45行+ 0x15字节C＃
它以这种方式重复，直到：
The maximum number of stack frames supported by Visual Studio has been exceeded.
这是一个新问题（对于Chris Ballard）：
更改了我所拥有的所有地方的代码之后，我比以前更加困惑，我有一个HUD.cs文件，它引用Player.cs文件中的Player_Stats类来获取变量，但我可以＆＃ 39;因为：
'HonourInBlood.Player_Stats' does not contain a constructor that takes 0 arguments
如果您浏览代码，查看每个类的开头，您可以看到只有一个引用网络现在导致问题，因为我将其更改为您向我展示的方式。
答案 0 :(得分：3)
好的 - 我看到了问题。
每次创建Player_Main时，它都会有一个字段，用于创建新的Player_Sprite
<强>但
Player_Sprite本身有一个字段可以创建另一个新的Player_Main，
这反过来会永久地创建一个新的Player_Sprite等（或者至少在你的堆栈溢出之前）
修改
我猜你想要一个Player_Main保留对Player_Sprite的引用，Player_Sprite需要记住创建它的Player_Main（不创建新的一个）。类似的东西：
public class Player_Main
{
public Player_Sprite psprite;
public Player_Main()
{
psprite = new Player_Sprite(this);
}
}
public class Player_Sprite
{
public Player_Main _pmain;
public Player_Sprite(Player_Main pmain)
{
_pmain = pmain;
}
}
答案 1 :(得分：0)
关于第二个问题。我怀疑您已更新Player_Stats类以在构造函数中接收Player_Main。
Player_Stats这不是必需的。这是因为Player_Stats 中的所有代码都不需要来访问Player_Main的方法或属性。 Player_Controls，Player_Abilities和Player_Movements
仅在Player_Sprite中需要，因为Draw方法访问pmain.pmove.position
在我写这篇文章时，我想到也许更好的实现只是将位置传递给Draw方法，所以：
public class Player_Sprite //This class deals with drawing the players sprite and animations
{
public Rectangle player;
public Texture2D playerAttack, playerWalk; //PLAYER TEXTURES
public Player_Sprite()
{
}
// .. methods removed for brevity
public void Draw(SpriteBatch spriteBatch, Player_Movement pmove)
{
spriteBatch.Draw(playerWalk, pmove.position, new Rectangle(0, 0, 64, 64), Color.White);
}
}
因此Player_Main.Draw成为：
public void Draw(SpriteBatch spriteBatch)
{
psprite.Draw(spriteBatch, pmove);
}
您不再需要将this传递给Player_Sprite构造函数。
编辑修订Player_Movement
public class Player_Movement //This class deals with all movement relating to the player ie sprinting
{
public Vector2 position, velocity, velocity_base, sprint;
public Player_Main pmain = null;
Game1 gamecore = new Game1();
public Player_Movement(Player_Main pmain)
{
this.pmain = pmain;
}
public void Update(GameTime gameTime)
{
KeyboardState KS = Keyboard.GetState();
//Player movement using arrow keys
if (KS.IsKeyDown(Keys.Up))
position.Y -= velocity.Y;
if (KS.IsKeyDown(Keys.Down))
position.Y += velocity.Y;
if (KS.IsKeyDown(Keys.Right))
position.X += velocity.X;
if (KS.IsKeyDown(Keys.Left))
position.X -= velocity.X;
//Making edge of screen stop player movement to prevent going off-screen
if (position.X < 0)
position.X = 0;
if (position.Y < 0)
position.Y = 0;
if (position.X + pmain.psprite.player.Width > gamecore.GraphicsDevice.Viewport.Width)
position.X = gamecore.GraphicsDevice.Viewport.Width - pmain.psprite.player.Width;
if (position.Y + pmain.psprite.player.Height > gamecore.GraphicsDevice.Viewport.Height)
position.Y = gamecore.GraphicsDevice.Viewport.Height - pmain.psprite.player.Height;
//
//SPRINTING
if (KS.IsKeyDown(pmain.pcontrols.sprintKey))
{
if (KS.IsKeyDown(Keys.Up) || KS.IsKeyDown(Keys.Down) || KS.IsKeyDown(Keys.Right) || KS.IsKeyDown(Keys.Left)) //You're only sprinting when you're moving, right?
{
if (pmain.pstats.currentStamina > 0) //Only when you have stamina can you run
{
velocity.X += sprint.X;
velocity.Y += sprint.X;
pmain.pstats.currentStamina -= pmain.pstats.stamina; //Decreases stamina
}
}
}
//
//
//SPRINTING
if (pmain.pstats.currentStamina > 0)
{
if (velocity.X > velocity_base.X) //When current velocity becomes greater than base velocity check whether space bar is released
{
if (KS.IsKeyUp(pmain.pcontrols.sprintKey))
velocity.X = velocity_base.X; //If it is, set current velocity back to base
}
if (velocity.Y > velocity_base.Y)
{
if (KS.IsKeyUp(pmain.pcontrols.sprintKey))
velocity.Y = velocity_base.Y;
}
if (velocity.X > velocity_base.X + sprint.X)
velocity.X = velocity_base.X + sprint.X;
if (velocity.Y > velocity_base.Y + sprint.Y)
velocity.Y = velocity_base.Y + sprint.Y;
//
}
if (pmain.pstats.currentStamina <= 0) //When you run out of stamina, set speed to normal
{
velocity.X = velocity_base.X;
velocity.Y = velocity_base.Y;
pmain.pstats.currentStamina = 0;
}
}
public void LoadContent(ContentManager Content)
{
position = new Vector2(400, 300);
velocity = new Vector2(4, 4); //Current velocity
velocity_base = new Vector2(4, 4); //Base velocity
sprint = new Vector2(6, 6); //Added velocity when sprinting
}
public void Draw(SpriteBatch spriteBatch)
{
}
}
在Player_Main构造函数中，执行以下操作：
public class Player_Main //This class deals with updating all other classes
{
public Player_Sprite psprite = new Player_Sprite();
public Player_Movement pmove = null;
public Player_Stats pstats = new Player_Stats();
public Player_Abilities pabilities = new Player_Abilities();
public Player_Controls pcontrols = new Player_Controls();
public Player_Main()
{
pmove = new Player_Movement(this);
}
// ... rest removed for brevity
}
