The DistanceSquared method calculates the squared distance between two 2D vectors. This method is useful when you need to compare distances without the computational cost of a square root operation, which is required for the actual distance calculation. The squared distance is often used in performance-critical code where the exact distance is not necessary, but a relative comparison is sufficient.
To use the DistanceSquared method, pass two Vector2 references as parameters. The method will return a float representing the squared distance between the two vectors.
Parameters:
a (ref Vector2): The first vector.b (ref Vector2): The second vector.Returns: float - The squared distance between the two vectors.
Vector2 pointA = new Vector2(1.0f, 2.0f); Vector2 pointB = new Vector2(4.0f, 6.0f); float squaredDistance = Vector2.DistanceSquared(ref pointA, ref pointB); // squaredDistance will be 25.0f
