Soldiers exercises

Aby uruchomić program najpierw:

pip install pipenv

pipenv run orders

Pojawi się program do zarządzania wojskiem. Wprowadzasz klawiaturą komendy tekstowe i widzisz w konsoli jak żółnierze zinterpretowali Twój rozkaz. Na początku ćwiczysz żóltodziobów, którzy nie mają pojęcia co do nich mówisz. Twoim zadaniem jest nauczenie ich co znaczą poszczególne komendy.

Możesz z nimi ćwiczyć pojedyńcze komendy przez testy:

pipenv install --dev
pipenv run tests

Przećwicz z żołnierzami musztrę. Wczuj się w rolę dowodzącego.

Wojsko może mieć bardzo dużo różnych układów. Nie ma ograniczonej liczby żołnierzy ich liczba i umieszczenie może być różne.

↑ - reprezentuje pojedyńczego żołnierza i jego kierunek w jakim patrzy

" " - puste miejsce

-Pole do ćwiczeń po jakim poruszają się żołnierze

W zależności od zaawansowania żołnierze potrafią reagować na różne komendy.

Początkowe położenie żołnierzy to:

[
[" "," "," "," "," "," "," "],
[" "," "," "," "," "," "," "],
[" "," ","↑","↑","↑"," "," "],
[" "," ","↑","↑","↑"," "," "],
[" "," ","↑","↑","↑"," "," "],
[" "," "," "," "," "," "," "],
[" "," "," "," "," "," "," "]
]

Greenhorns:

Greenhorn wiedzą, że na pole gdzie ktoś już stoi nie powinno sie się wchodzić. Stoją w miejscu, gdy rozkaz wymaga wejścia na kogoś. Zdarza im się jednak wychodzić poza pole do ćwiczeń i nie wracać.

  • "Turn West!" - ← wszyscy odwracają się w lewo
  • "Turn East!" - → wszyscy odwracają się w prawo,
  • "Turn South!" - ↓ wszyscy odwracają się do tyłu,
  • "Go forward!" - wszyscy idą o jeden krok w kierunku jakim są zwróceni
  • "Go forward n step!", - wszyscy idą o n kroków w kierunku jakim są zwróceni
  • "Turn to me!" - ↑ wszyscy odwracają się do dowodzącego czyli na górę planszy
  • "Go scatter" - rozproszyć się - wszyscy zmieniają położenie:
    • losowo wybrany element planszy,
    • odwróceni w losowym kierunku,
    • nie jest zabrionione by powrócił na swoje poprzednie miejsce i kierunek patrzenia.

Corporals:

Greenhorn po poznaniu wszystkich komend stają się corporal.

Są wytrwali i nigdy nie uciekają z pola ćwiczeń. Gdy rozkaz wymaga wyjścia poza pole to stawają na ostatnim możliwym polu.

Poza tym potrafią rozpoznawać do którego rzędu lub kolumny należą.

[" "," "," "," "," "," "," "] wiersz
[" "," "," "," "," "," "," "]  |
[" "," "," "," "," "," "," "]  v
[" "," ","↑","↑","↑"," "," "]  1
[" "," ","↓","↓","↓"," "," "]  2
[" "," ","↓","↓","↓"," "," "]  3
[" "," "," "," "," "," "," "]
          |   |   |
kolumna-> 1   2   3

Gdy są rozproszeni to wciąż mają świetną orientację:

[" "," "," "," "," "," "," "],wiersz
[" ","↑","→"," "," ","→"," "], 1
[" "," "," "," "," ","↓"," "], 2
[" "," "," "," "," "," "," "],
[" ","↑"," "," "," "," "," "], 3
[" ","←"," "," ","←","↓"," "], 4
[" "," "," "," "," "," "," "]
kol   1   2       3   4

Dzięki temu są w stanie rozpoznawać więcej komend:

  • "1st row, ", "2nd row, ", "3rd row, ", "nth row",
  • "1st column, ", "2nd column, ", "3rd column, ", "nth column"
  • "Even rows, ",
  • "Even columns, ",
  • "Odd rows, ",
  • "Odd columns, "

Te komendy są wstawiane na początku rozkazów dla wojska:

command:"3rd row, Turn East!"

[" "," "," "," "," "," "," "] wiersz
[" "," "," "," "," "," "," "]  |
[" "," "," "," "," "," "," "]  v
[" "," ","↑","↑","↑"," "," "]  1
[" "," ","↑","↑","↑"," "," "]  2
[" "," ","→","→","→"," "," "]  3
[" "," "," "," "," "," "," "]
          |   |   |
kolumna-> 1   2   3

Sergeants

Sergeant potrafi wszystko co greenhorn i corporal. Mają szczególną umiejętność jaką jest rozpoznawanie kierunków. Potrafią obracać się w kierunkach względem aktualnego położenia.

  • "Turn left!"
  • "Turn right!"
  • "Turn backward!"

Na przykład

[" "," "," "," "," "," "," "]
[" "," "," "," "," "," "," "]
[" "," "," "," "," "," "," "]
[" "," ","↑","↑","↑"," "," "]
[" "," ","↓","↓","↓"," "," "]
[" "," ","↓","↓","↓"," "," "]
[" "," "," "," "," "," "," "]

"Turn left!"

[" "," "," "," "," "," "," "]
[" "," "," "," "," "," "," "]
[" "," "," "," "," "," "," "]
[" "," ","←","←","←"," "," "]
[" "," ","→","→","→"," "," "]
[" "," ","→","→","→"," "," "]
[" "," "," "," "," "," "," "]

Rozpoznają także komendy:

  • "Stand still!" - każda następna komenda jest ignorowana
  • "Move your asses!" - żołnierze przestają ignorować komendy

Możesz oczywiście wybrać wiersz lub kolumnę dla tych komend.
