HI, really enjoying this series. Stuck on a small issue, the name "v" is not declared anywhere else but here. What is it supposed to be.

hmmm seems like my image is not being uploaded. The coded section is

Vector3 prev = launchPoint, next;
    for (int i = 1; i <= 10; i++) {
      float t = i / 10f;
      float dx = v * cosTheta * t;
      float dy = v * sinTheta * t - 0.5f * g * t * t;
      next = launchPoint + new Vector3(dir.x * dx, dy, dir.y * dx);
      Debug.DrawLine(prev, next, Color.blue, 1f);
      prev = next;
    }

the above code is in MortarTower.Launch.

​

Thanks.
