The DistanceSquared method calculates the squared distance between the current Vector3 instance and a target Vector3. This method is useful for performance optimization when you only need to compare distances, as it avoids the computational cost of a square root operation required by the Distance method.
To use the DistanceSquared method, you need to have a Vector3 instance and a target Vector3 reference. The method will return a float representing the squared distance between the two vectors.
Vector3 pointA = new Vector3(1.0f, 2.0f, 3.0f); Vector3 pointB = new Vector3(4.0f, 5.0f, 6.0f); float squaredDistance = pointA.DistanceSquared(ref pointB); // squaredDistance now holds the value 27.0f, which is the squared distance between pointA and pointB.
