Movement Script Not Working Correctly

Questions & Answers

The problem started when I started using transform.Translate and Space.Self to make the player move relative to its own axis, rather than globally. I have no clue what the problem is now, it just goes in random directions now.
This is the main movement script in question:

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

public class Movement : MonoBehaviour
{
    public float playerMovementSpeed = 1f;
    private float gravity = -9.1f; // dw about this, ended up not using it
    [SerializeField] private float gravityMultiplier = 1f; // dw about this, ended up not using it
    private float velocity; // dw about this, ended up not using it

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKey(KeyCode.W)) {
            transform.Translate(transform.forward * Time.deltaTime * playerMovementSpeed, Space.Self);
        }
        if (Input.GetKey(KeyCode.A)) {
            transform.Translate(-transform.right * Time.deltaTime * playerMovementSpeed, Space.Self);
        }
        if (Input.GetKey(KeyCode.S)) {
            transform.Translate(-transform.forward * Time.deltaTime * playerMovementSpeed, Space.Self);
        }
        if (Input.GetKey(KeyCode.D)) {
            transform.Translate(transform.right * Time.deltaTime * playerMovementSpeed, Space.Self);;
        }
    }
}

The camera movement was done in a separate script, nothing’s wrong with it.
There aren’t any errors in the console.
Lmk if you need any more information.

When you are using transform.forward and transform.right you do not need to set translation space to Space.Self you are over-correcting the direction vector.
