Передвижение персонажа лучше делать через AddForce
Вот пример из моего проекта
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public CharacterController controller;
public AudioClip[] steps;
public AudioSource audioSource;
private bool stepPlayed;
public float timeBetweenSteps;
public float speed = 12f;
public float gravity = -9.81f;
public float jumpHeight = 3f;
public Transform groundCheck;
public float groundDistance = 0.4f;
public LayerMask groundMask;
Vector3 velocity;
bool isGrounded;
// Update is called once per frame
void Update()
{
isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
if (isGrounded && velocity.y < -2f)
velocity.y = -2f;
float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");
Vector3 move = transform.right * x + transform.forward * z;
controller.Move(move * speed * Time.deltaTime);
if (Input.GetButtonDown("Jump") && isGrounded)
velocity.y = Mathf.Sqrt(jumpHeight * -2 * gravity);
velocity.y += gravity * Time.deltaTime;
controller.Move(velocity * Time.deltaTime);
StepSoundPlay();
}
private void StepSoundPlay()
{
if (!stepPlayed)
{
if (isGrounded && (Input.GetAxisRaw("Vertical") != 0 || Input.GetAxisRaw("Horizontal") != 0))
{
stepPlayed = true;
audioSource.clip = steps[Random.Range(0, steps.Length)];
audioSource.Play();
StartCoroutine(Wait());
}
}
}
private IEnumerator Wait()
{
yield return new WaitForSeconds(timeBetweenSteps);
stepPlayed = false;
}
}
Данный код подходит для First Person игр
Так же в нем есть шаги (StepSounds)
