If statement not working

Questions & Answers
1

I am trying to make it so a game object flips if the player is not in it’s raycast but it does not seem to work. I know that the raycast works fine because I tested it by logging the name of the object the raycast hit, but my if statement with a boolean does not seem to work. Please help. Thanks!

    public Transform viewPoint;
    public Transform target;

    public float speed = 3f;
    public float viewDistance = 10f;

    bool FacingPlayer;

      void Update()
      {     

          RaycastHit2D hitTarget = Physics2D.Raycast(viewPoint.position, viewPoint.right);

        if (Vector3.Distance(transform.position, target.position) < viewDistance) 
        { 
            if (hitTarget)
            {
                FacingPlayer = true;
            } 
            
            if (!FacingPlayer)
            {
                Flip();
            }
        }      
    }

    void Flip()
    {
        transform.Rotate(0f, 180f, 0f);
    }

@goldenbergdaniel8 I believe that the second boolean statement will (almost) never run. This is because you are first checking for if the raycast was a success, not if it hit the player. I suggest you do something like this:

if (hitTarget.collider.tag != "Player")
{
      Flip();
}

This statement:

if (hitTarget)

is pointless since hitTarget is a struct. This statement will always be true. You may pay more attention to the example given in the documentation. You have to check if hitTarget.collider is null or not. If it’s null, nothing was hit. If it’s not null it contains a reference to the collider that was hit.

So it should be

if (hitTarget.collider != null)
{
    FacingPlayer = true;
}

Note that you never set FacingPlayer back to false. So once this if condition is true, FacingPlayer will be set to true and stay true until you explicitly set it back to false. In the code you’ve posted you never set it back to false.
