我现在有一个看起来像这样的功能:
public static bool IsKeyDownWithDelayPassed(Keys key, int delay)
{
bool timeElapsed = stopWatch.ElapsedMilliseconds > delay;
bool isKeyDown = currentKeyboardState.IsKeyDown(key);
if (timeElapsed && isKeyDown)
{
stopWatch.Restart();
}
return timeElapsed && isKeyDown;
}
这完美无缺,但一次只能使用一个键。例如,如果我想使用箭头键并进行对角线移动(同时按住向下和向下箭头键),则它不起作用。
我想到了一个涉及Dictionary
映射Keys
到Stopwatch
的解决方案,但这似乎有点过于复杂。我错过了可以简化这项任务的东西吗?
感谢。

使用它:
Dictionary<Keys, DateTime> keytimes = new Dictionary<Keys, DateTime>();
public bool IsKeyDownWithDelayPassed(Keys key, long delay)
{
if(!keytimes.Keys.Contains(key) || keytimes[key] == DateTime.MinValue)
return false;
long elapsed = DateTime.Now.Ticks - keytimes[key].Ticks;
return delay < elapsed;
}
private void KeyDownEvent(object sender, KeyEventArgs e)
{
keytimes[e.KeyData] = DateTime.Now;
}
private void KeyUpEvent(object sender, KeyEventArgs e)
{
keytimes[e.KeyData] = DateTime.MinValue;
}
