How do I prevent my object from doubling speed when I press two keys

Questions & Answers

Basically if I press keys such as ‘W,D’ ‘W,A’ ‘S,A’ ‘S,D’ it doubles the speed of my object and I simply don’t want that so if there are any tweaks to the code you suggest please advise me!

using UnityEngine;

public class Player_Movement : MonoBehaviour
{
   public float speed = 5f;
    


    // Update is called once per frame
    void FixedUpdate()
    {
        MoveUp();
        MoveDown();
        MoveRight();
        MoveLeft();
        Sprint();
     



    }

    void MoveUp ()
    {
        if (Input.GetKey("w"))
        {
            transform.Translate(speed * Time.deltaTime, 0, 0);

        }

    }

    void MoveDown()
    {
        if (Input.GetKey("s"))
        {
            transform.Translate(-speed * Time.deltaTime, 0, 0);

        }

    }

    void MoveLeft()
    {
        if (Input.GetKey("a"))
        {
            transform.Translate(0, 0,speed * Time.deltaTime);

        }

    }

    void MoveRight()
    {
        if (Input.GetKey("d"))
        {
            transform.Translate(0, 0,-speed * Time.deltaTime);

        }

    }

   public void Sprint()
    {
        if (Input.GetKeyDown(KeyCode.LeftShift))
        {

            speed = 10f;
            
        }
       else if (Input.GetKeyUp(KeyCode.LeftShift) )
        {
            speed = 5f;
           
        }
    }

You need to combine the movement to a vector and normalize it’s length. This should help you on the way.

Vector3 v = new Vector3(0, 0, 0);
void FixedUpdate()
{
    Sprint();
    v.x = v.z = 0;
    if (Input.GetKey("w")) v.x += 1;
    if (Input.GetKey("s")) v.x -= 1;
    if (Input.GetKey("a")) v.z += 1;
    if (Input.GetKey("d")) v.z -= 1;
    if (v.sqrMagnitude > 0.1f) v.Normalize();
    v *= speed * Time.deltaTime;
    transform.Translate(v);
}
