The IsNearZeroLength property of the Vector2 struct is a boolean property that indicates whether the squared length of the vector is less than 1e-8. This is useful for determining if a vector is effectively zero in length, which can be important in calculations where very small vectors should be treated as zero to avoid numerical instability or unnecessary computations.
Use the IsNearZeroLength property when you need to check if a Vector2 instance is close to having zero length. This can be particularly useful in physics calculations, collision detection, or any scenario where you need to determine if a vector is negligible.
Vector2 vector = new Vector2(0.0000001f, 0.0000001f);
if (vector.IsNearZeroLength)
{
// Handle the case where the vector is effectively zero
// For example, you might want to ignore this vector in a calculation
}
