Movement doesn't change when player rotates

Questions & Answers
1

I am attempting to create my own player controller, but what is happening is the movement does not change with the rotation

C#

PlayerMovement.cs

using UnityEngine;
using System;
using System.Collections;

public class PlayerMovement : MonoBehaviour {

	public float moveSpeed = 1.0f;



	// Use this for initialization
	void Start () {


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

		if (Input.GetKey (KeyCode.W)) {

				transform.position += Vector3.forward * moveSpeed;
			}


		if (Input.GetKey (KeyCode.S)) {
			
			transform.position += Vector3.back * moveSpeed;
			
		}
		if (Input.GetKey (KeyCode.D)) {
			
			transform.position += Vector3.right * moveSpeed;
			
		}
		if (Input.GetKey (KeyCode.A)) {
			
			transform.position += Vector3.left * moveSpeed;

			
		}
	
	}

}

MouseLook.cs

using UnityEngine;
using System.Collections;

public class MouseLook : MonoBehaviour {

	public float mouseLook = 1.0f;

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {


		if(Input.GetKey(KeyCode.LeftArrow)){

			transform.Rotate(Vector3.down * mouseLook);
		
		}

		if(Input.GetKey(KeyCode.RightArrow)){
			
			transform.Rotate(Vector3. * mouseLook);
			
		}
	
	}
}

In your PlayerMovement script you should use the following:

transform.forward // move forward relative to player rotation
-transform.forward // move back relative to player rotation
transform.right // move right relative to player rotation
-transform.right // move left relative to player rotation

So here’s the corrected PlayerMovement script:

using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour {


    public float moveSpeed = 1.0f;



    // Use this for initialization
    void Start()
    {



    }

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

        if (Input.GetKey(KeyCode.W))
        {

            transform.position += transform.forward * moveSpeed;
        }


        if (Input.GetKey(KeyCode.S))
        {

            transform.position += -transform.forward * moveSpeed;

        }
        if (Input.GetKey(KeyCode.D))
        {

            transform.position += transform.right * moveSpeed;

        }
        if (Input.GetKey(KeyCode.A))
        {

            transform.position += -transform.right * moveSpeed;


        }

    }
}

If you’re trying to make FPS style controls, why not use the ones provided by Unity?
