2D Player Rotation using Joystick in Unity3D

Questions & Answers
1

I am trying to rotate a gameobject along z-axis using Joystick, but its rotating y-axis. I might missed some math calculation. Any Help?

void FixedUpdate()
    {
        // get input from joystick
        rightJoystickInput = rightJoystick.GetInputDirection();

        float xMovementRightJoystick = rightJoystickInput.x; // The horizontal movement from joystick 02
        float zMovementRightJoystick = rightJoystickInput.y; // The vertical movement from joystick 02


        // if there is only input from the right joystick
        if (rightJoystickInput != Vector3.zero)
        {
            // calculate the player's direction based on angle
            float tempAngle = Mathf.Atan2(zMovementRightJoystick, xMovementRightJoystick);
            xMovementRightJoystick *= Mathf.Abs(Mathf.Cos(tempAngle));
            zMovementRightJoystick *= Mathf.Abs(Mathf.Sin(tempAngle));

            // rotate the player to face the direction of input
            Vector3 temp = transform.position;
            temp.x += xMovementRightJoystick;
            temp.z += zMovementRightJoystick;
            Vector3 lookDirection = temp - transform.position;
            if (lookDirection != Vector3.zero)
            {
                rotationTarget.localRotation = Quaternion.Slerp(rotationTarget.localRotation, Quaternion.LookRotation(lookDirection) * Quaternion.Euler(0, 45f, 0), rotationSpeed * Time.deltaTime);
            }
        }
    }

float zMovementRightJoystick = rightJoystickInput.z;
