如何在几秒钟内失去控制？

Question

在GameState.Running开始时，我想在3秒内停止输入键，之后，每当我的角色受到伤害时，我想在1秒内失去控制，有人能告诉我该怎么做吗？

        public override void Update(GameTime gameTime, KeyboardState Current, KeyboardState Old)
    {
        float elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds;

        if (TimeGetReady < 0)
        {
            LockKey = false;
        }
        else
        {
            LockKey = true;
            TimeGetReady -= elapsed;
        }

        if (LockKey == false)
        {
            CurrentKeys = Current;
            OldKeys = Old;
        }


        if (CurrentKeys.IsKeyDown(Keys.P))
        {
            if (!OldKeys.IsKeyDown(Keys.P))
                if (IsPause == true)
                    IsPause = false;
                else
                    IsPause = true;
        }
        if (IsPause == true)
        {
            return;
        }
        Update(elapsed);
        if (CurrentKeys.IsKeyDown(Keys.Left))
        {

            KeyLeft = true;
            if (HPF < 3)
                HPF += 2;

            PushHorizontal += 5;
            Face = -1;

        }
        else

                HPF += 2;
            Face = 1;

        }
        else

            {
                KeyRight = false;
            }

        if (KeyLeft == true || KeyRight == true)

            if (VPF < 8)
                VPF += 3;

        }

您需要一些仅在需要时更新的InputManager。以下是InputManager基本版本的示例。

public override void Update(){
    if(updateKeyboard) {InputManager.Update()}
}

新的InputManager类

public static class InputManager
{
    public static void Update()
    {
        _previousKeyboardState = _currentKeyboardState;
        _currentKeyboardState = Keyboard.GetState();
    }

    public static bool IsKeyDown(Keys key) 
    {
        return _currentKeyboardState.IsKeyDown(key);
    }

    public static bool IsKeyUp(Keys key)
    {
        return _currentKeyboardState.IsKeyUp(key);
    }

    public static bool OnKeyDown(Keys key)
    {
        return _currentKeyboardState.IsKeyDown(key) && _previousKeyboardState.IsKeyUp(key);
    }

    public static bool OnKeyUp(Keys key)
    {
        return _currentKeyboardState.IsKeyUp(key) && _previousKeyboardState.IsKeyDown(key);
    }

    private static KeyboardState _currentKeyboardState;
    private static KeyboardState _previousKeyboardState;
}
