使数组动画化

目前正在尝试为我使用XNA 4.0在c#中制作的游戏中的一组敌人精灵动画

使用动画代码

namespace Rotationgame
{
class Animation
{
    Texture2D texture;
    Rectangle rectangle;
    Vector2 position;
    Vector2 origin;
    Vector2 velocity;
    int currentFrame;
    int frameHeight;
    int frameWidth;
    float timer;
    float interval = 150;
    public Animation(Texture2D newTexture, Vector2 newPosition, int newFrameHeight, int newFrameWidth)
    {
        texture = newTexture;
        position = newPosition;
        frameHeight = newFrameHeight;
        frameWidth = newFrameWidth;
    }
    public void Update(GameTime gameTime)
    {
        rectangle = new Rectangle(currentFrame * frameWidth, 0, frameWidth, frameHeight);
        origin = new Vector2(rectangle.Width / 2, rectangle.Height / 2);
        position = position + velocity;
        if (Keyboard.GetState().IsKeyUp(Keys.F1))
        {
            AnimateRight(gameTime);
            velocity.X = 0;
        }
        else if (Keyboard.GetState().IsKeyUp(Keys.F2))
        {
            AnimateLeft(gameTime);
            velocity.X = -0;
        }
        else velocity = Vector2.Zero;
    }
    public void AnimateRight(GameTime gameTime)
    {
        timer += (float)gameTime.ElapsedGameTime.TotalMilliseconds / 2;
        if (timer > interval)
        {
            currentFrame++;
            timer = 0;
            if (currentFrame > 1)
                currentFrame = 0;
        }
    }
    public void AnimateLeft(GameTime gameTime)
    {
        timer += (float)gameTime.ElapsedGameTime.TotalMilliseconds / 2;
        if (timer > interval)
        {
            currentFrame++;
            timer = 0;
            if (currentFrame > 1)
                currentFrame = 0;
        }
    }

    public void Draw(SpriteBatch spriteBatch)
    {
        spriteBatch.Draw(texture, position, rectangle, Color.White, 0f, origin, 1.0f, SpriteEffects.None, 0);
    }
}
}

数组

public class Game1 : Microsoft.Xna.Framework.Game
{
    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;

    Animation[] invaders;

protected override void Initialize()
    {
       invaders = new Animation[13];
        // TODO: Add your initialization logic here
        base.Initialize();
    }
  protected override void LoadContent()
    {
        // Create a new SpriteBatch, which can be used to draw textures.
        spriteBatch = new SpriteBatch(GraphicsDevice);

// Array of Space Invaders
        invaders[0] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(400, 400), 115, 96);
        invaders[1] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(427, 310), 115, 96);
        invaders[2] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(427, 490), 115, 96);
        invaders[3] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(490, 250), 115, 96);
        invaders[4] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(490, 550), 115, 96);
        invaders[5] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(580, 240), 115, 96);
        invaders[7] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(580, 560), 115, 96);
        invaders[8] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(670, 550), 115, 96);
        invaders[9] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(670, 250), 115, 96);
        invaders[10] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(730, 490), 115, 96);
        invaders[11] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(730, 310), 115, 96);
        invaders[12] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(757, 400), 115, 96);
     }
protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);
        spriteBatch.Begin();
// Drawing Invaders
                foreach (Animation invader in invaders)
                    invaders.Draw(spriteBatch);
}
        spriteBatch.End();

一切工作在visual Studio的代码，但我得到一个错误的绘制方法说:"错误1"系统。Array'不包含'Draw'的定义，也没有扩展方法'Draw'接受第一个类型为'System '的参数。Array'可以找到(您是否缺少using指令或程序集引用?)"

你知道哪里出错了吗?
