Help! | Third Person Camera, Player Controller - Strafe Movement

Unity Engine
1

Hello Unity Forum,

I’ve only started using Unity a month ago and I began creating this 3D tennis style game after watching videos and reading a few forums, now I’m stuck.
Currently the camera and player are rotatable so I need help with making both the camera and player focus the middle of the field as the player strafes parallel to the field when you click and hold down the left mouse button.
Thank you guys in advance.

[ ThirdPersonCamera.cs ]

using UnityEngine;
using System.Collections;

public class ThirdPersonCamera : MonoBehaviour
{

    public bool lockCursor;
    public float mouseSensitivity = 10;
    public Transform target;
    public float dstFromTarget = 2;
    public Vector2 pitchMinMax = new Vector2(-40, 85);

    public float rotationSmoothTime = .12f;
    Vector3 rotationSmoothVelocity;
    Vector3 currentRotation;

    float yaw;
    float pitch;

    void Start()
    {
        if (lockCursor)
        {
            Cursor.lockState = CursorLockMode.Locked;
            Cursor.visible = false;
        }
    }

    void LateUpdate()
    {
        yaw += Input.GetAxis("Mouse X") * mouseSensitivity;
        pitch -= Input.GetAxis("Mouse Y") * mouseSensitivity;
        pitch = Mathf.Clamp(pitch, pitchMinMax.x, pitchMinMax.y);

        currentRotation = Vector3.SmoothDamp(currentRotation, new Vector3(pitch, yaw), ref rotationSmoothVelocity, rotationSmoothTime);
        transform.eulerAngles = currentRotation;

        transform.position = target.position - transform.forward * dstFromTarget;

    }

So… what exactly are the problem(s) you’re seeing?

Is the camera not rotating around the field the way you’d expect it to?

Or is the player not strafing the way they should?

I’m sorry I’m new at this. There is nothing wrong with the current script. I need to add strafing to the script but I don’t know how.
