Im not exactly sure what you mean by convert. Do you mean something like this?

        RaycastHit hitInfo;
        if(Physics.Raycast(rayOrigin, Vector3.up * directionY, out hitInfo, rayLength, collisionMask))
        {
            velocity.y = (hitInfo.distance - skinWidth) * directionY;
            rayLength = hitInfo.distance;
        }

Ya like this only, but here why if condition came?

The if condition is to see if the raycast hits anything. No point trying to do something with the result if it’s null.
