计算正确的音高

        public double GetPitchToFace(double Z2, double Z1, double X2, double X1)
    {            
        double Arc;
        Arc = Math.Atan2(Z2 - Z1, X2 - X1);
        return Arc;
    }

我正在尝试制定正确的音高，以“面对”特定点。

使用AtAN2（如上所述）似乎返回了正确的值，但是游戏中的音高系统似乎很奇怪。

与其将逆时针从0 radian持续到6.2，它从0开始到3雷达，然后跳到-3雷迪安，然后再次回到0。

希望您能理解上面的不良示例。

我需要一种从奇怪的音高 /径向系统转换为标准0-6.2弧度以返回正确的音高的方法。

谢谢。

        return Arc;
    }

I am attempting to work out the correct pitch in order to "face" a specific point.

Using Atan2 (as seen above) seems to return the correct values however in-game the pitch system seems to work rather strangely.

Instead of increasing anti-clockwise from 0 radian all the way back to 6.2 it starts from 0 up to 3 radian then jumps down to -3 radian and works its way back to 0 once again.

Hopefully you can understand the bad drawing example above.

I need a way to convert from that strange pitch / radian system to the standard 0 - 6.2 radians in order to return a correct pitch.

Thanks.

由于MATH.ATAN2方法返回角度θ（在弧度中），因此，当-π≤θ≤π时，它将产生负值。输入点位于第三或第四象限。

要仅返回正值（IE 0≤θ≤2π），可以使用简单的数学。由于2π是一个完整的旋转，因此可以添加每当Math.atan2方法返回负值时，可以添加。这只会为您提供所需范围的价值。

 public double GetPitchToFace(double Z2, double Z1, double X2, double X1)
    {            
        double Arc;
        double theta = Math.Atan2(Z2 - Z1, X2 - X1);
        Arc = (theta >= 0) ? theta : (2*Math.PI + theta);
        return Arc;
    }

Since the Math.Atan2 method returns the angle θ (in radians) such that -π ≤ θ ≤ π it will yield negative values when the input point is in the third or fourth quadrant.

To return only positive values (i.e. 0 ≤ θ ≤ 2π) one can use simple mathematics. Since 2π is a full rotation you can add that whenever the Math.Atan2 method returns a negative value. This will only give you values in your wanted range.

 public double GetPitchToFace(double Z2, double Z1, double X2, double X1)
    {            
        double Arc;
        double theta = Math.Atan2(Z2 - Z1, X2 - X1);
        Arc = (theta >= 0) ? theta : (2*Math.PI + theta);
        return Arc;
    }
