'Microsoft.Xna.Framework.Vector2'是'type'但像变量一样使用？

Question

对，我已经在谷歌上查过了，我仍然不知道如何修复它。任何帮助吗?

    public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;
        Texture2D spritesheet;
        Rectangle sourceRect;
        Rectangle destinationRect;
        int spriteWidth = 50;
            int spriteHeight = 50;
            Texture2D maze;
            Vector2 mazePosition = Vector2(0f, 0f);
            Color[] spritetextureData;
            Color[] mazeTextureData;
            int direction = 0;
            bool persotHit = false;

        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            Content.RootDirectory = "Content";
        }
        /// <summary>
        /// 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

        protected override void Initialize()

        }

        protected override void LoadContent()
        {
            // Create a new SpriteBatch, which can be used to draw textures.
            spriteBatch = new SpriteBatch(GraphicsDevice);
            // TODO: use this.Content to load your game content here
        }

        }

        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);
        }
        /// <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);
            // TODO: Add your drawing code here
            base.Draw(gameTime);
        }
    }
}

创建新对象的方法:

Vector2 mazePosition = new Vector2(0f, 0f);

而不是:

Vector2 mazePosition = Vector2(0f, 0f);

注意new这个词
