C#规格化(类似于向量)
本文关键字:向量 类似于 规格化 | 更新日期: 2023-09-27 18:29:54
我的移动对象中的代码:
ObjectX.Location.Add(Velocity * Utils.GetMoveDir(start, destination));
实用功能:
public static PointF GetMoveDir(PointF start, PointF destination)
{
PointF substraction = destination.SubStract(start);
if (substraction == PointF.Empty) // If-statement is needed because normalizing a zero value results in a NaN value
return PointF.Empty;
else return substraction.Normalize(); // I need something for this
}
我无法工作的分机:
public static PointF Normalize(this PointF A)
{
throw new NotImplementedException(); // How do I solve this to make it like: http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.vector2.normalize.aspx
}
请注意,我不使用XNA框架。
public static PointF Normalize(this PointF A)
{
float distance = Math.Sqrt(A.X * A.X + A.Y * A.Y);
return new PointF(A.X / distance, A.Y / distance);
}
另请参阅此处的第一段,了解什么是归一化向量(单位向量)以及如何计算它。
public static PointF Normalize(this PointF A)
{
float length = Math.Sqrt( A.X*A.X + A.Y*A.Y);
return new PointF( A.X/length, A.Y/length);
}
