我收到一个错误，

“错误 1 ​​'GameStateManagement.GameplayScreen.Draw(Microsoft.Xna.Framework.GameTime, GameStateManagement.InputState)'：找不到合适的方法来覆盖”

我不知道出了什么问题。我是编程新手，并从我的大学课程中获得了一些代码。其余的我自己做。我很茫然，我该如何解决这个问题？

代码

        /// Draws the gameplay screen.
        /// </summary>
        public override void Draw(GameTime gameTime, InputState input)
        {
            // This game has a blue background. Why? Because! Not anymore, haha!

            var colorMatch = new Dictionary<int, Color>();
            colorMatch.Add(1, Color.LightBlue);
            colorMatch.Add(2, Color.CornflowerBlue);
            colorMatch.Add(3, Color.Blue);
            colorMatch.Add(4, Color.White);
            colorMatch.Add(5, Color.LightGreen);
            colorMatch.Add(6, Color.Green);
            colorMatch.Add(7, Color.Purple);
            colorMatch.Add(8, Color.Chocolate);
            colorMatch.Add(9, Color.Crimson);
            colorMatch.Add(10, Color.IndianRed);

            ScreenManager.GraphicsDevice.Clear(ClearOptions.Target,
                                               colorMatch[munchieSpeed], 0, 0);

            spriteBatch.Begin();

            // Draw munchies

            int playerIndex = (int)ControllingPlayer.Value;

            KeyboardState keyboardState = input.CurrentKeyboardStates[playerIndex];
            GamePadState gamePadState = input.CurrentGamePadStates[playerIndex];

            for (int i = 0; i < noOfMunchies; i++)
            {
                if (munchieAnimationCount[i] == 0)
                {
                    // Draw frame 1
                    if ((gamePadState.DPad.Right == ButtonState.Pressed) ||

您只能覆盖超类中定义的方法。这意味着当您实现一个继承自的类时Game（就像您在编写 XNA 游戏时所做的那样），您可以从Game具有以下签名的类中覆盖 draw 方法：

protected virtual void Draw (
    GameTime gameTime
)

在您的代码中，您试图覆盖一个方法，

protected virtual void Draw (
     GameTime gameTime,
     InputState input
)

这在您的超类中不存在，Game.

（另见Game.Draw 方法。）

尝试删除关键字override.

public void Draw(GameTime gameTime, InputState input)
