Как изменить код? Есть код для CharacterConroller, а нужно этот код переделать для CapsuleColider

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class PlayerMovement : MonoBehaviour
{
    
    public CharacterController controller;
    public float speed = 10f;
    public float gravity = -18f;
    public float jumpHeight = 3f;
    public float lerpmultiplier = 7f;
    public FixedJoystick fixedJoystick;
    public float horiz;
    public float vert;
    public Transform groundCheck;
    public LayerMask groundMask;
    public float groundDistance = 0.4f;
 
    Vector3 velocity;
    bool isGrounded;
    // Update is called once per frame
    void Update()
    {
        horiz = Mathf.Lerp(horiz,fixedJoystick.Horizontal,Time.deltaTime * lerpmultiplier);
        vert = Mathf.Lerp(vert,fixedJoystick.Vertical,Time.deltaTime * lerpmultiplier);
        isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
        if (isGrounded && velocity.y < 0)
            velocity.y = -2f;
        float x = horiz;
        float z = vert;
 
        if (Input.GetButtonDown("Jump") && isGrounded)
        {
            velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
 
        Vector3 move = transform.right * x + transform.forward * z;
        controller.Move(move * speed * Time.deltaTime);
 
        velocity.y += gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);
        
        if (Input.GetKey("left shift"))
            speed = 20f;
        else
            speed = 10f;
    }
}
