展示PNG动画精灵

首先,我为动画精灵创建一个类

public class AnimatedSprite
  {
      Point _frameSize;
      int _currentFrame;
      private readonly int _frame = 4;
      private readonly Texture2D _sprite;
      public AnimatedSprite(Texture2D texture, int frame)
      {
          _frameSize = new Point(texture.Width/frame, texture.Height);
          _frame = frame;
          _sprite = texture;
      }

      public void Update()
      {
          _currentFrame = (_currentFrame + 1) % _frame;
      }

      public void Draw(SpriteBatch spriteBatch)
      {
          spriteBatch.Draw(
              _sprite,
              Vector2.Zero,
              new Rectangle(_currentFrame*_frameSize.X, 0,
                            _frameSize.X, _frameSize.Y
                  ),
              Color.White, 0,
              Vector2.Zero, 1,
              SpriteEffects.None, 0
              );

      }
  }

在页面中进行调用

private AnimatedSprite Player { get; set; }

        protected override void LoadContent()
        {
            _spriteBatch = new SpriteBatch(GraphicsDevice);
            Player = new AnimatedSprite(
        Content.Load<Texture2D>("Roles\\Ningke\\stand")
        , 4);
            TargetElapsedTime = new TimeSpan(0, 0, 0, 0, 125);

        }

protected override void Update(GameTime gameTime)
        {
            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
                this.Exit();
            KeyboardTemplate(_graphics.ToggleFullScreen, Keys.Enter, Keys.RightAlt);
            KeyboardTemplate(this.Exit, Keys.F4, Keys.LeftControl);
            Player.Update();
            base.Update(gameTime);
        }
protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);
            _spriteBatch.Begin();
            Player.Draw(_spriteBatch);
            _spriteBatch.End();
            base.Draw(gameTime);
        }

即可实现动画精灵效果

挺好玩的.
