加载一个静态图片，左右移动，真没啥意思，鼠标单击上去都没反应，这也太山寨了吧。
来点稍微给力的，\(^o^)/
新建项目，加载图片，和第一章是一样的 Texture2D people; protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); people = Content.Load (@"Image/PlayerMagic"); // TODO: use this.Content to load your game content here } 这里有一个地方，就是当你加载Body0这个gif的时候，最好转换成png或者jpg之类的，而且最好不要太大，因为它加载图片大会出现一个这样的异常
意思都能看懂，就是图片太大，Textrue2D容积小，当然有解决办法，我还没想到，以后知道了补上，如果是程序无法识别的图片格式，他会报格式不识别这个错误
//这里是图片中每一帧图片的大小 Point pictureSize = new Point(150, 150); Point currentFrame = new Point(0, 0); //这里是你的图片有几帧，10是行，1是列，因为图片只有一行，所以列没啥用，那个Body0可以用得着 Point pictureNum = new Point(10, 1); public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; //因为程序1秒刷新60次，你可以自定义刷新的时间，这里是每0.12秒刷新 TargetElapsedTime = new TimeSpan(0, 0, 0, 0, 120); //鼠标可见 IsMouseVisible = true; } 因为是从一张图片动态取帧，所以才有Point pictureNum = new Point(10, 1);这样的变量10列1行，其实用两个变量记录也行，一个记录行，一个记录列
protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.AlphaBlend); spriteBatch.Draw(people, Vector2.Zero, new Rectangle(currentFrame.X * pictureSize.X, currentFrame.Y * pictureSize.Y, pictureSize.X, pictureSize.Y), Color.White, 0, Vector2.Zero, 1, SpriteEffects.None, 0); spriteBatch.End(); base.Draw(gameTime); } Draw这里，要使用重载函数来动态的用new Rectangle来获取显示的位置了
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 ++currentFrame.X; if (currentFrame.X >= pictureNum.X) { currentFrame.X = 0; } base.Update(gameTime); } Update这里加入一个判断，当Rectangle超过图片大小时候，清零重来
运行，左上角会有一个gif图片，当然，还有另外一种方法
我这里面加了8张图片，可以再Draw中这么处理 protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.AlphaBlend); //spriteBatch.Draw(people, Vector2.Zero, //new Rectangle(currentFrame.X * pictureSize.X, //currentFrame.Y * pictureSize.Y, //pictureSize.X, //pictureSize.Y), //Color.White, 0, Vector2.Zero, //1, SpriteEffects.None, 0); spriteBatch.Draw(list[currentFrame.X], Vector2.Zero, null, Color.White); ++currentFrame.X; if (currentFrame.X >=8) { currentFrame.X = 0; } spriteBatch.End(); base.Draw(gameTime); } 之前我有这样的操作，也能达到相同效果
Listlist = new List (); protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); people = Content.Load (@"Image/PlayerMagic"); for (int i = 0; i < 8; i++) { list.Add(Content.Load (string.Format(@"Image/{0}",i))); } // TODO: use this.Content to load your game content here }
两个方法一样的，注意的是如果用第二种方法，你要把Update中的方法先注释掉
进入下一个问题图片随鼠标移动
//记录前一个鼠标的位置 MouseState preMouseState; //图片的位置 Vector2 ringsPosition = Vector2.Zero; //移动的速度 const float ringsSpeed = 4;
我们新加几个变量
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 ++currentFrame.X; if (currentFrame.X >= pictureNum.X) { currentFrame.X = 0; } MouseState mouseState = Mouse.GetState(); if (mouseState.X != preMouseState.X || mouseState.Y != preMouseState.Y) ringsPosition = new Vector2(mouseState.X-75, mouseState.Y-75); preMouseState = mouseState; base.Update(gameTime); } Update的时候记录一下鼠标的位置，说白了就是把图片移动到当前鼠标位置呗，这里也要改一下
protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.AlphaBlend); spriteBatch.Draw(people, ringsPosition, new Rectangle(currentFrame.X * pictureSize.X, currentFrame.Y * pictureSize.Y, pictureSize.X, pictureSize.Y), Color.White, 0, Vector2.Zero, 1, SpriteEffects.None, 0); //spriteBatch.Draw(list[currentFrame.X], ringsPosition, null, Color.White); //++currentFrame.X; //if (currentFrame.X >= 8) //{ // currentFrame.X = 0; //} spriteBatch.End(); base.Draw(gameTime); } 红色也要改一下
spriteBatch.Draw(list[currentFrame.X], Vector2.Zero, null, Color.White); ++currentFrame.X; if (currentFrame.X >=8) { currentFrame.X = 0; } 还有这个东西也要改一下，红色的那个，我程序已经改过了，如果注释错了可能会报错
