Simple movement system only moves on the X axis (is a problem)-CodePudding

When using this code on unity (I am very new to coding so please be patient) the character will only move on the X axis. It is just a square that cannot slow down without direct input.

float _walkspeed;
float _inputHorizontal;
float _inputVertical;

// Start is called before the first frame update
void Start()
{
    _rb = gameObject.GetComponent<Rigidbody2D>();

    _walkspeed = 5.5f;
}

// Update is called once per frame
void Update()
{
    _inputHorizontal = Input.GetAxisRaw("Horizontal");

    if (_inputHorizontal != 0)
    {
        _rb.AddForce(new Vector2(_inputHorizontal * _walkspeed, 0f));
    }
}
private void FixedUpdate()
{
    _inputVertical = Input.GetAxisRaw("Vertical");
    if (_inputVertical != 0)
    {
        _rb.AddForce(new Vector2(_inputVertical * _walkspeed, 0f));
    }
}

}

CodePudding user response：

Add vertical force in y-axis in your FixedUpdate() method

private void FixedUpdate()
{
    _inputVertical = Input.GetAxisRaw("Vertical");
    if (_inputVertical != 0)
    {
        _rb.AddForce(new Vector2(0f, _inputVertical * _walkspeed));
    }
}

CodePudding user response：

Do as Geeky Quentin mentioned, and also move your horizontal and vertical input into one function, either FixedUpdate() or Update(). If not, the character will move faster (or possibly slower) on the Y axis.

private void FixedUpdate()
{
    _inputHorizontal = Input.GetAxisRaw("Horizontal");

    if (_inputHorizontal != 0)
    {
        _rb.AddForce(new Vector2(_inputHorizontal * _walkspeed, 0f));
    }

    _inputVertical = Input.GetAxisRaw("Vertical");
    if (_inputVertical != 0)
    {
        _rb.AddForce(new Vector2(_inputVertical * _walkspeed, 0f));
    }
}
