Question

按住AS，SD，DW或WA的组合键移动我的物体后，它会成功对角移动并旋转到正确位置，但释放按键后，它会旋转回0,90,180或者360取决于释放我的键后最近的旋转，我想这是因为我离开了键的那一帧，所以它运行该代码并将其移动到0,90,180,360。但我不知道如何解决它。

我希望我提供了足够的信息，并感谢您的帮助。

我一起按下AW键

释放按键后，它不会保持这种状态，而是向左或向上移动

我会保存最后一个时间戳，并检查第二个密钥释放是否在特定时间范围内。如果它在（例如）20ms内释放，请不要重置它。

例如:(伪）

private bool[] _directionKeysPressed = new bool[4];
private DateTime _previousKeyRelease;

private void KeyDown(object sender, EventArgs e)
{
    _keyPressedCount++;

    switch(keys)
    {
       case(W): _directionKeysPressed[0] = true;
       case(D): _directionKeysPressed[1] = true;
       // .................
    }
}

private void KeyUp(object sender, EventArgs e)
{
    _keyPressedCount--;

    if(_keyPressedCount == 0)
    {
        // all keys released
        _directionKeysPressed[] <--- last direction...

        // reset all bools
        return;
    }

    // ONLY if the key is released outside the 20 ms, reset the key.
    if(_previousKeyRelease.AddMilliseconds(20) < DateTime.UTCNow)
    {  // RESET KEY
        switch(keys)
        {
            case(W): _directionKeysPressed[0] = false;
            case(D): _directionKeysPressed[1] = false;
            // .................
        }
    }

    _previousKeyRelease = DateTime.UTCNow;
}

我个人会用Int32中的一个位域来做这个，但是对于一个bool数组来说更清楚。

沿对角线旋转物体并防止其返回90,180,0,360度
