-# Frobnicator (this is a template)
+[](https://classroom.github.com/a/M0kyOMLZ)
+# Aplikacja z mini-grami logicznymi
-## Authors
-- Andrzej Głuszak (@agluszak on GitHub)
-- Linus Torvalds (@torvalds on GitHub)
+## Autorzy
+- Jan Kuźma
-## Description
-Frobnicator is going to be a platformer game similar to Super Mario Bros made using Korge game engine.
+## Opis
+Planuję stworzyć aplikacje desktopową zawierającą kilka mini gier logicznych, jeszcze się zastanawiam nad konkretnymi przykładami, ale będzie to coś jak sudoku/krzyżówki/mastermind itp, potencjalnie jakaś przygodowa gra tekstowa.
-## Features
-- map generator
-- shooting
-- enemy AI
-- game state saving and loading
-- scores
+## Funkcjonalności
+- gry logiczne singleplayer z kilkoma poziomami,
+- ranking graczy/historia wyników,
+- pomoc dla gracza (podpowiedzi/tutoriale),
+- zapis stanu gry.
## Plan
-In the first part we're going to implement the basics: movement, physics and shooting. The enemies will simply bounce from one edge of the platform to the other. There will be only a single map.
+W pierwszej części planuję storzyć obsługę ekranów startowych, menu głównego, podstawową nawigacji, jakiś przykład łamigłówki.
-In the second part we're going to add random map generator, saving/loading, scores and a more sophisticated AI.
+W drugiej części planuję dodać nowe łamigłówki, rankingi/historie wyników, wskazówki dla graczy oraz potencjalnie (jeśli wyżej wymienione punkty okażą się zbyt mało czasochłonne) tryb multiplayer (być może rozgrywany na jednym telefonie, coś aka gra turowa- np kółko i krzyżyk). Dodatkowo, po konsultacji- zostanie dodany zapis stanu gry.
-## Libraries
-- Korge (https://korge.org/)
-- kotlinx-serialization (https://github.com/Kotlin/kotlinx.serialization)
+## Biblioteki
+Będzie to apliakcja desktopowa (rezygnuję z android studio), z użyciem Compose.
+
+# Podsumowanie części pierwszej
+Struktura projektu- w głównym folderze aplikacji znajdują się następujące komponenty:
+- Main.kt, który pozwala na uruchomienie aplikacji,
+- DatabaseConfig.kt, który zapewnia konfigurację połączenia z bazą danych
+- populateDb.kt, który umożliwia załadowania początkowych planszy sudkou do bazy danych. Aby populować bazę danych,
+należy odpowiednio zmienić kod w Main.kt (uruchomić jedynie z funkcją populate())
+- /backend/sudoku/Node.kt - deklaracja klasy pojedynczej komórki na planszy sudoku
+- /backend/sudoku/SudokuBoard.kt - deklaracja klasy planszy sudoku, zawiera m.in serializacje oraz funckje sprawdzające poprawność planszy
+- /backend/entities/SudokuBoards - zawiera deklaracje tabeli przechowującej sudoku
+- /ui/screens/GameMenu.kt - główny widok statowego menu
+- /ui/screens/games/MastermindScreen.kt - placeholder screen dla gry Mastermind
+- /ui/screens/games/TickTakToe.kt - placeholder screen dla gry Kółko i Krzyżyk
+- /ui/screens/games/SudokuScreen.kt - główny ekran dla sudoku, duża część implementacji
+- /ui/sudokuComponents/NumberPad.kt - design dla klawiatury do wprowadzania numerków na plansze
+- /ui/sudokuComponents/Popup.kt - design dla popup-ów, jeszcze nie używany
+- /ui/sudokuComponents/SudokuBoardConfig.kt - konfiguracja kolorów dla planszy sudoku
+- /ui/sudokuComponents/SudokuBoardUI.kt - design dla planszy sudoku
+
+Aplikacja zawiera podstawową nawigacje, oraz logikę gry sudoku, wraz z przechowywaniem stanu gry w bazie danych.
+Stan gry można zapisywać, chwilowo istnieje jedna plansza. Jest zaimplementowana również walidacja stanu planszy, czy
+sprawdzanie wygranej gracza.
+
+W projeckie użyłem takich bibliotek/funkcjonalności jal:
+- Compose Desktop- było to wyzwanie, ponieważ nie omawialiśmy tego jeszcze na zajęciach, jednak praca z tą biblioteką okazała się bardzo przyjemna,
+- Exposed – biblioteka służąca do obsługi połączeń z bazą danych w Kotlinie,
+- Korutyny- użyte trochę na siłę, do komunikacji z bazą danych. Aby symulować dłuższą operację, ręcznie dodaję
+sleep(1000) w funkcjach komunikujących się z bazą danych.
+
+# Jak uruchomić aplikację?
+Można wywołać polecenie ./gradlew run. Ważna notatka- w funkcji main w pliku Main.kt jest wywoływana funckja populate().
+Czyści ona lokalnie bazę danych, oraz insertuje do niej 2 plansze sudoku. Jeżeli chcemy, aby stan planszy zapisywał się
+między wywołaniami aplikacji- po pierwszym uruchomieniu należy usunąć (wykomentować) tą linijkę.

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.
