MyCharacterController derived by BaseCharacterController, Here are where we adjust ECM code.

using ECM.Common;
using ECM.Controllers;
using UnityEngine;
 
public sealed class MyCharacterController : BaseCharacterController
{
    public Transform playerCamera;
 
    public float customSpeedWalk = 3f;
    public float customSpeedRun = 10f;
 
    public void makeWalk()
    {
        speed = customSpeedWalk;
    }
 
    public void makeRun()
    {
        speed = customSpeedRun;
    }
 
    protected override void HandleInput()
    {
        // Handle your custom input here...
        moveDirection = new UnityEngine.Vector3
        {
            x = Input.GetAxisRaw("Horizontal"),
            y = 0.0f,
            z = Input.GetAxisRaw("Vertical")
        };
 
        if(!isJumping) jump = Input.GetButton("Jump");
 
        //walk = Input.GetButton("Fire3");
 
        // Transform moveDirection vector to be relative to camera view direction
        moveDirection = moveDirection.relativeTo(playerCamera);
    }
}

ExploreCameraController, we control our camera here.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using DG.Tweening;
using Sirenix.OdinInspector;
 
public class ExploreCameraController : MonoBehaviour
{
    public Transform mainCamera;
 
    public float xVal = 0;
    private float turnSpeed = 4;
    private Vector3 offsetX;
 
    public float height = 15f;
    public float distance = 12f;
 
    public float lookAtSensitivity = 0.3f;
    public float rotateSensitivity = 0.3f;
    public float mouseSensitive = 5;
 
    public float turnSpeedSensitivity = 0.05f;
 
    void Awake()
    {
        offsetX = new Vector3(0, height, distance);
        transform.DOMove(new Vector3((mainCamera.position + offsetX).x, height, (mainCamera.position + offsetX).z), rotateSensitivity);
    }
 
    [Button]
    void updateHeightDistance()
    {
        offsetX = new Vector3(0, height, distance);
    }
 
    //public float zVal = 0;
 
    // Update is called once per frame
    void LateUpdate()
    {
 
        this.transform.DOLookAt(mainCamera.position, lookAtSensitivity);
        //this.transform.DOMove(new Vector3(mainCamera.position.x + xVal, this.transform.position.y, mainCamera.position.z + -xVal), 1f);
 
        if (Input.GetKey(KeyCode.Mouse0))
        {
            offsetX = Quaternion.AngleAxis(Input.GetAxis("Mouse X") * (turnSpeed * mouseSensitive), Vector3.up) * offsetX;
        }
        if (Input.GetKey(KeyCode.E))
        {
            offsetX = Quaternion.AngleAxis(1 * (turnSpeed * turnSpeedSensitivity * Time.deltaTime), Vector3.up) * offsetX;
        }
        if (Input.GetKey(KeyCode.Q))
        {
            offsetX = Quaternion.AngleAxis(-1 * (turnSpeed * turnSpeedSensitivity * Time.deltaTime), Vector3.up) * offsetX;
        }
 
        //transform.position = mainCamera.position + offsetX;
        transform.DOMove(new Vector3((mainCamera.position + offsetX).x, height, (mainCamera.position + offsetX).z), rotateSensitivity);
    }
}

We use script to assign animation into our character.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Animancer;
using Animancer.Examples;
using ECM.Controllers;
 
public class CharacterAnimationController : MonoBehaviour
{
 
    [SerializeField] private AnimancerComponent _Animancer;
    [SerializeField] private ClipTransition _Idle;
    [SerializeField] private ClipTransition _Move;
    [SerializeField] private ClipTransition _Run;
    [SerializeField] private ClipTransition _Action;
 
    private MyCharacterController myCharacterController;
 
    private void Start()
    {
        myCharacterController = FindObjectOfType<MyCharacterController>();
    }
 
    private void Update()
    {
 
        if (Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.D))
        {
            _Animancer.Play(_Move);
 
            myCharacterController.makeWalk();
 
            if (Input.GetKey(KeyCode.LeftShift))
            {
                _Animancer.Play(_Run);
                myCharacterController.makeRun();
            }
        }
        else
        {
            _Animancer.Play(_Idle);
        }
    }
}
