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, call it on an instance of Vector3 and pass a reference to another Vector3 as the target. The method will return a float representing the squared distance between the two vectors.
Vector3 pointA = new Vector3(1, 2, 3); Vector3 pointB = new Vector3(4, 5, 6); float squaredDistance = pointA.DistanceSquared(ref pointB); // squaredDistance now holds the value 27, which is the squared distance between pointA and pointB.
