我是XNA的新手，發現了一個在線教程，用於製作像使用它的pong遊戲。我正在閱讀教程，但即使它是確切的同樣code.Here是我Game1.cs *代碼：我在一些基本的XNA 4.0代碼中遇到了一個錯誤
using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Media;
namespace WindowsGame1
{
/// <summary>
/// This is the main type for your game
/// </summary>
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
Paddle paddle;
Rectangle screenBounds;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
screenBounds = new Rectangle(
0,
0,
graphics.PreferredBackBufferWidth,
graphics.PreferredBackBufferHeight);
}
/// <summary>

protected override void Initialize()
{
// TODO: Add your initialization logic here
base.Initialize();
}
/// <summary>

protected override void LoadContent()
{
spriteBatch = new SpriteBatch(GraphicsDevice);
Texture2D tempTexture = Content.Load<Texture2D>("paddle");
paddle = new Paddle(tempTexture, screenBounds);
}
/// <summary>
/// UnloadContent will be called once per game and is the place to unload

protected override void UnloadContent()
{
// TODO: Unload any non ContentManager content here
}

protected override void Update(GameTime gameTime)
{
// Allows the game to exit
if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
this.Exit();
paddle.Update();
base.Update(gameTime);
}
/// <summary>
/// This is called when the game should draw itself.
/// </summary>
/// <param name="gameTime">Provides a snapshot of timing values.</param>
protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.CornflowerBlue);
spriteBatch.Begin();
paddle.Draw(spriteBatch);
spriteBatch.End();
base.Draw(gameTime);
}
}
}
我也有這個類
using System.Text;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
namespace BreakingOut
{
class Paddle
{
Vector2 position;
Vector2 motion;
float paddleSpeed = 8f;
KeyboardState keyboardState;
GamePadState gamePadState;
Texture2D texture;
Rectangle screenBounds;
public Paddle(Texture2D texture, Rectangle screenBounds)
{
this.texture = texture;
this.screenBounds = screenBounds;
SetInStartPosition();
}
public void Update()
{
motion = Vector2.Zero;
keyboardState = Keyboard.GetState();
gamePadState = GamePad.GetState(PlayerIndex.One);
if (keyboardState.IsKeyDown(Keys.Left))
motion.X = -1;
if (keyboardState.IsKeyDown(Keys.Right))
motion.X = 1;
if (gamePadState.ThumbSticks.Left.X < -.5f)
motion.X = -1;
if (gamePadState.ThumbSticks.Left.X > .5f)
motion.X = 1;
motion.X *= paddleSpeed;
position += motion;
LockPaddle();
}
private void LockPaddle()
{
if (position.X < 0)
position.X = 0;
if (position.X + texture.Width > screenBounds.Width)
position.X = screenBounds.Width - texture.Width;
}
public void SetInStartPosition()
{
position.X = (screenBounds.Width - texture.Width)/2;
position.Y = screenBounds.Height - texture.Height - 5;
}
public void Draw(SpriteBatch spriteBatch)
{
spriteBatch.Draw(texture, position, Color.White);
}
public Rectangle GetBounds()
{
return new Rectangle(
(int)position.X,
(int)position.Y,
texture.Width,
texture.Height);
}
}
}
這段代碼到目前爲止僅僅是創建一個槳，用戶可以move.I也有槳的圖像正確加載。這是它產生的錯誤：
The type or namespace name 'Paddle' could not be found (are you missing a using directive or an assembly reference?)
這是產生這種錯誤的部分：將非常感激
Paddle paddle;
我已經確切地做了什麼教程說做，它的工作對任何人制造的tutorial.Any的幫助，如果您需要更多信息只是問。謝謝。
