The Length property of the Vector2 struct returns the magnitude of the vector. The magnitude, or length, of a vector is a measure of how long the vector is, calculated as the square root of the sum of the squares of its components. This property is useful for determining the size or distance represented by the vector in 2D space.
To access the Length property, simply call it on an instance of Vector2. This property is read-only and provides a float value representing the vector's magnitude.
Vector2 vector = new Vector2(3, 4); float length = vector.Length; // length will be 5, as the vector (3, 4) has a magnitude of 5 (3^2 + 4^2 = 9 + 16 = 25, sqrt(25) = 5)
