Whack-a-mole scenario

As is, this test take 45 seconds on my computer to complete. So I'm not sure whether we actually want this to be part of the test suite.

I have now fixed this by adding a wait 64 in the "polling" loop of the built robots.

It also helped to reduce the map size and number of strikes against the gopher.

The integration test runs much faster with this.

Nice! My solution (written without looking at yours) is below. Looks like they are functionally pretty similar.

I think we definitely need to fix the race condition before merging. On the other hand I don't have a strong opinion about the teleport, I just wanted to hear your thought process and why you designed it that way.

def mod = \a. \b. (a - b*(a/b)) end

def forever = \c. c ; forever c end

def x4 = \c. c;c;c;c end

def drill_mound = \d.
  h <- scan d;
  if (h == inr "mound") { drill d } {}
end

def gopher_turret =
  forever (
    x4 ( turn left; drill_mound forward );
    drill_mound down
  )
end

def idoN_rec : int -> int -> (int -> cmd unit) -> cmd unit = \k. \n. \c.
  if (k == n) {} {c k; idoN_rec (k+1) n c}
end

def idoN : int -> (int -> cmd unit) -> cmd unit = idoN_rec 0 end

def doN : int -> cmd unit -> cmd unit = \n. \c. idoN n (\_. c) end

def place_turret = \row. \col.
  if (mod (2*row + col) 5 == 0) { build {gopher_turret}; return () } {}
end

def carpet_row = \r.
  idoN 28 (\c. place_turret r c; move);
  turn back; doN 28 move; turn left; move; turn left
end

def carpet = idoN 19 carpet_row end

Wow, this is a huge challenge, I am not sure I am ready to face that gopher. 😄

[kostmo]

I think this is ready now.

Looks great! I had to make a minor change to my solution since the type of drill changed but after that change it still worked, and I like the new non-teleporting gopher.

I especially like this challenge because it feels like it might just be possible if you type really fast but it quickly gets tedious/impossible and you start to wonder if there is a better way...
