我一直在尝试旋转（并有一个平滑的旋转）字符到相应的用户输入，但我总是有一个问题，我需要知道如何解决它。由于非平滑旋转工作，我试图使一个是顺利的。
我使用的代码：

if (LeftKey == true)
{
        if (RightKey == true)
        {
            PlayerOrientation = 0;
        }
        else
        {
            PlayerOrientation = 45;
        }
}
else
{
        if (RightKey == true)
        {
            PlayerOrientation = -45;
        }
        else
        {
            PlayerOrientation = 0;
        }
    }
}
else if (RightKey == false && LeftKey == true)
{
    if (DownKey == true)
    {
        if (UpKey == true)
        {
            PlayerOrientation = 90;
        }
        else
        {
            PlayerOrientation = 135;
        }
    }
    else
    {
        if (UpKey == true)
        {
            PlayerOrientation = 45;
        }  
        else
        {
            PlayerOrientation = 90;
        }
    }
}
else if (UpKey == false && DownKey == true)
{
    if (LeftKey == true)
    {
        if (RightKey == true)
        {
            PlayerOrientation = 180;
        }
        else
        {
            PlayerOrientation = 135;
        }
    }
    else
    {
        if (RightKey == true)
        {
            PlayerOrientation = -135;
        }
        else
        {
            PlayerOrientation = 180;
        }
    }
}
else if (LeftKey == false && RightKey == true)
{
    if (DownKey == true)
    {
        if (UpKey == true)
        {
            PlayerOrientation = -90;
        }
        else
        {
            PlayerOrientation = -135;
        }
    }
    else
    {
        if (UpKey == true)
        {
            PlayerOrientation = -45;
        }
        else
        {
            PlayerOrientation = -90;
        }
    }
}

if (UpKey == true || DownKey == true || RightKey == true || LeftKey == true)
{
    if (ThePlayerOrientation != PlayerOrientation)
    {
        float difference = (PlayerOrientation - ThePlayerOrientation) / 20;
        thePlayerPos += difference;

        if (PlayerOrientation == thePlayerPos)
        {
            ThePlayerOrientation = PlayerOrientation;
            thePlayerPos = PlayerOrientation;
        }
    }
}

如果有人能帮助我，那将是非常有帮助的。
