1. Hello Xna for Windows Phone 7
1.1 新建 xna工程。
vs将会生成下面的工程。
其中XnaHelloPhoneContent工程中包含了项目中需要使用资源文件（bitmap file，effect file，sprite file），XnaHelloPhone工程中包含了对XnaHelloPhoneContent项目的引用，在代码就可直接使用这些资源，例如如果想要加载字体资源，代码如下：
font = this.Content.Load("SpriteFont1");
这里的Load方法中的参数是该字体的asset name。
1.2 修改代码。
Game1.cs：
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.Input.Touch;
using Microsoft.Xna.Framework.Media;
namespace XnaHelloPhone
{
///
/// This is the main type for your game
///
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
// 显示的文字
private string text = "Hello Window Phone 7!";
// 文字字体
private SpriteFont font;
// 文字位置
private Vector2 textPosition;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
// Frame rate is 30 fps by default for Windows Phone.
TargetElapsedTime = TimeSpan.FromTicks(333333);
}
///
/// Allows the game to perform any initialization it needs to before starting to run.
/// This is where it can query for any required services and load any non-graphic
/// related content.Calling base.Initialize will enumerate through any components
/// and initialize them as well.
///
protected override void Initialize()
{
// TODO: Add your initialization logic here
base.Initialize();
}
///
/// LoadContent will be called once per game and is the place to load
/// all of your content.
///
protected override void LoadContent()
{
// Create a new SpriteBatch, which can be used to draw textures.
spriteBatch = new SpriteBatch(GraphicsDevice);
font = this.Content.Load("SpriteFont1");
Vector2 textSize = font.MeasureString(text);
Viewport viewpoint = this.GraphicsDevice.Viewport;
this.textPosition = new Vector2( (viewpoint.Width - textSize.X) / 2,
(viewpoint.Height - textSize.Y) / 2 );
// TODO: use this.Content to load your game content here
}
///
/// UnloadContent will be called once per game and is the place to unload
/// all content.
///
protected override void UnloadContent()
{
// TODO: Unload any non ContentManager content here
}
///
/// Allows the game to run logic such as updating the world,
/// checking for collisions, gathering input, and playing audio.
///
/// Provides a snapshot of timing values.
protected override void Update(GameTime gameTime)
{
// Allows the game to exit
if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
this.Exit();
// TODO: Add your update logic here
base.Update(gameTime);
}
///
/// This is called when the game should draw itself.
///
/// Provides a snapshot of timing values.
protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.Navy);
// TODO: Add your drawing code here
spriteBatch.Begin();
spriteBatch.DrawString(font, this.text,
textPosition,
Color.White);
spriteBatch.End();
base.Draw(gameTime);
}
}
}
