Error messages with 2d character sprite flipping and movement.

Questions & Answers

I’m making a 2d game but when I try to flip the sprites with a code I get errors.

No overload for for method ‘Move’ takes 1 argument/ the name ‘move’ doesn’t exist in the current context. Please help me fix this or suggest another way of doing it. Here’s the script.

void Update ()
{

    float x = Input.GetAxisRaw("Horizontal");
    float y = Input.GetAxisRaw("Vertical");

    Vector2 direction = new Vector2(x, y).normalized;
    Move (direction);
}

void Move (Vector2 direction, float move)
{
    Vector2 min = Camera.main.ViewportToWorldPoint (new Vector2(0, 0));
    Vector2 max = Camera.main.ViewportToWorldPoint (new Vector2(1, 1));

    max.x = max.x - 0.225f;
    min.x = min.x + 0.225f;

    max.y = max.y - 0.285f;
    min.y = min.y + 0.285f;

    Vector2 pos = transform.position;

    pos += direction * speed * Time.deltaTime;

    pos.x = Mathf.Clamp (pos.x, min.x, max.x);
    pos.y = Mathf.Clamp(pos.y, min.y, max.y);

    transform.position = pos;

    if (move > 0 && !m_FacingRight)
    {
        // ... flip the player.
        Flip();
    }
    // Otherwise if the input is moving the player left and the player is facing right...
    else if (move < 0 && m_FacingRight)
    {
        // ... flip the player.
        Flip();
    }
}

private void Flip()
{
    // Switch the way the player is labelled as facing.
    m_FacingRight = !m_FacingRight;

    // Multiply the player's x local scale by -1.
    Vector3 theScale = transform.localScale;
    theScale.x *= -1;
    transform.localScale = theScale;
}

}

This…

Move (direction);

Is calling the local “Move” method. Looking at that method, it requires 2 arguments, but you’re only giving it a single argument.

void Move (Vector2 direction, float move)

So, it needs both a Vector2 and a float. Looking at the code, the 2nd arg just seems to be a float that’s analyzed to determine motion direction (positive being right and negative being left). With that in mind, I’d guess you want to change this:

Move (direction);

to this:

Move (direction, x);
