I know you said this will change soon, but I had to create a more circular set of allowable grids using this.
int testDistance = (Mathf.Abs(x) * Mathf.Abs(x)) + (Mathf.Abs(z) * Mathf.Abs(z));
if (testDistance > (maxShootDistance * maxShootDistance))
{
continue;
}
Nice.
You don’t have to Mathf.Abs() those values because they will be positive once you multiplied them, so
int testDistance = (x * x) + (z * z);
will be ever so slightly more performant
Very good point, cheers 
Yup that’s a great simple way to do that. The final version later on in the course asks the Pathfinding system to get the path length
Do you see those single grid position “spikes” you get at 0,7 and 7,0? Those may not be to your taste. If you want to have a subjectively nicer-looking circle, you can add 0.5f to your maxShootDistance before squaring it.

Oh that’s an interesting tip! Personally I still prefer the main method since I like the strategy of moving further if going straight but that’s a great tip!
I did something similar:
//making a circular shooting range:
double radiusDistance = Math.Sqrt((x*x) + (z*z));
int testDistance = Convert.ToInt32(radiusDistance);
if (testDistance > maxShootDistance)``
