LineRendered / Raycast not matching over distance

[Fariel]

I have two bits of code that should be doing the same thing but are very much not doing the same thing.

lr.SetPosition(0, transform.position);
lr.SetPosition(1, transform.up.normalized * 999f);

and

RaycastHit2D[] hits = Physics2D.CircleCastAll(transform.position, laserFireWidth, transform.up, 999f, ~(1 << LayerMask.NameToLayer("Ship")));

As I get close to 100 units away from the source of the linerenderer, it always seems to be to the left of my player. Significantly so, too. See attached picture.

However, the ray will hit me and do damage. So clearly the ray is working fine, as it should be looking at the player. The line should be doing the same thing as the ray, but it’s not. It’s off a little.

Why?

Edit: Full source code for the controller below:

    float angle = 0f;

    public float timeBetweenShots = 10f;
    public float timeBetweenChargeAndShoot = 0.5f;

    public float currentWidth = 0f;

            angle = Mathf.Atan2(targetDirection.y, targetDirection.x) * Mathf.Rad2Deg;
            angle += 90f;
            transform.rotation = Quaternion.RotateTowards(transform.rotation, Quaternion.AngleAxis(angle, Vector3.forward), turnSpeed * Time.deltaTime);
            //transform.Rotate(0f, 0f, 90f);

    }

Edit: As this code was used for a game jam game, we’ve gone ahead and submitted the game with this bug still in it. You can witness this bug yourself here: EAT by Unibear Studio

I would absolutely love to fix this. Can anyone help?

My guess its because its a CircleCast, and the circle is hitting the player. I don’t know what your width is set to, so I could be wrong. Good luck in the Jam, I entered the compo, barely finished in time.

Hey Maybe you can help me with something. My pictures wont show up on my Game Page.
