Moving a player character on local axis

Unity Engine
1

I am making a 2.5D type of game in a 3D environment where the player can move in all 3 axis (z for forward and backward, y for jumping and x for the depth of the level). I have a script where if the A or D keys are pressed (based on a Boolean), the player will turn 90 degrees (if it is set to false, which is the default) or turn -90 degrees (if it is set to true). My problem is that the “forward” movement for the player is always in the world’s Z axis rather than the player’s Z axis. How can I make it so the player moves in either the local Z axis or the world’s X axis?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Movement : MonoBehaviour
{
    public CharacterController controller;

    public float speed = 6f;

    public float gravity = 9.81f;

    public float jumpSpeed = 5f;

    public float rotationSpeed = 90f;

    private float directionY;

    public Transform player;

    public bool turned = false;

    // Update is called once per frame
    void Update()
    {

        float vertical = Input.GetAxisRaw("Vertical");
        Vector3 direction = new Vector3(0f, 0f, vertical).normalized;
        direction.y = directionY;

      //character movement
        controller.Move(direction * speed * Time.deltaTime);

        //turnign
        if (turned == false && Input.GetKey(KeyCode.D))
        {
            transform.Rotate (0, 90, 0);
            turned = true;
        }
        else
        {
            if(turned == true && Input.GetKey(KeyCode.A))
            {
                transform.Rotate (0, -90, 0);
                turned = false;
            }
        }
     
        //jumping
        if (Input.GetButtonDown("Jump") && controller.isGrounded)
        {
            directionY = jumpSpeed;
        }

        directionY -= gravity * Time.deltaTime;

    }


}

Multiply your vector3 euler direction with the players quaternion rotation (quaternion * vector3, doesn’t go the other way), this activates the quaternions magic and somehow rotates your vector. :shrugs:

edit: wait, doesn’t transform.rotate take rotation into account? (i never use it myself)

I appreciate the response but I found a far simpler script than the one I showed in the post, so I scrapped it and edited the character movement script according to what I needed.
