unity topdown movement 2d code example

Example 1: unity 2D top down movement

public float moveSpeed = 5f;

    public Rigidbody2D rb;

    private Vector2 _movement;

    // Update is called once per frame
    void Update()
    {
        _movement.x = Input.GetAxisRaw("Horizontal");
        _movement.y = Input.GetAxisRaw("Vertical");
        _movement = new Vector2(_movement.x, _movement.y).normalized;
    }

    private void FixedUpdate()
    {
        rb.MovePosition(rb.position + _movement * moveSpeed * Time.fixedDeltaTime);
    }

Example 2: top down 2d movement unity

public float Speed = 5f; 

private void Update()
    {
        input = new Vector3(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"), 0);
        Vector3 velocity = input.normalized * Speed;
        transform.position += velocity * Time.deltaTime;
    }
