用ADSW来控制前后左右，J表示开火，J不能连续按

_+表示速度档位、

DateTime _LastPress = DateTime.MinValue;        Keys _PrevKey = Keys.None;        List
      
        CtlKeys = new List
       
        () { Keys.A, Keys.D, Keys.S, Keys.W, Keys.J, Keys.Add, Keys.Subtract };        protected override bool ProcessKeyPreview(ref Message m)        {                                   var key = (Keys)m.WParam.ToInt32();            if (!CtlKeys.Contains(key))            {                return false;            }            if (m.Msg == WM_KEYDOWN)            {                if (key == Keys.J && _PrevKey==key)                {                                                            var delay=(DateTime.Now - _LastPress).TotalMilliseconds ;                    Console.WriteLine(delay);                                            if (delay < 1000)                    {                        Console.WriteLine("连续按J");                        _LastPress = DateTime.Now;                        return true;                    }                }                Console.Write("按下->");                Console.WriteLine(key);                _PrevKey = key;                _LastPress = DateTime.Now;                         }            if (m.Msg == WM_KEYUP)            {                Console.Write("释放->");                Console.WriteLine(key);            }                        return base.ProcessKeyPreview(ref m);        }
