poswojsku.pl
Witaj w poradniku wydawnictwa poswojsku.pl, dzięki któremu wspólnie zaprogramujemy grę mobilną Falling Jumping Shapes. Stworzymy projekt od pomysłu przez grafikę, aż do kompleksowego zaprogramowania w najwspanialszym języku programowania: JavaScript. Aby jednak to osiągnąć, najpierw nauczę Ciebie podstaw kilku niesamowitych technologii: nowoczesnej odmiany JavaScript, czyli tzw. ES6+, React Native, React, CSS w wersji do aplikacji mobilnej, Android. Aplikacje będziemy tworzyli w IDE: VSCodium lub możesz użyć inny edytor kodu, np. Visual Studio Code. Poradnik zawiera kod gry wraz z omówieniem oraz podstawową wiedzę niezbędną do tworzenia aplikacji mobilnych za pomocą frameworka React Native - Część II Aplikacje Mobilne Wprowadzenie. Ale jeżeli posiadasz już podstawy wiedzy, możesz od razu przejść do tworzenia gry. OPIS GRY DO WYKONANIA Planujemy zbudować grę, posiadającą trzy poziomy, a właściwie warianty: prosty - nazwijmy go SIMPLE oraz przypiszmy do niego oznaczenie 'zero' trudniejszy - nazwijmy go MEDIUM oraz przypiszmy do niego oznaczenie 'one' nieco szalony - nazwijmy go CRAZY oraz przypiszmy do niego oznaczenie 'two' Użyłem określenia 'warianty' a nie poziomy, gdyż można uruchomić każdy z nich bez względu na przejście przez poprzedni. Technicznie rzecz ujmując będą to trzy zupełnie niezależne od siebie gry, ale oparte na podobnym wyglądzie oraz grafice. Gracz będzie miał za zadanie kliknięcie w spadającą kulkę, tyle razy, aby wyszła za jedną z bocznych krawędzi. Zasady gry są bardzo proste: Wybierając z menu nawigacyjnego jeden z wariantów, Gracz rozpocznie grę, Po kliknięciu w przycisk START GAME pojawia się na górnej krawędzi kulka o losowym kolorze, Kulka opada powoli w dół, Gracz ma za zadanie kliknąć kulkę, a ona za każdym kliknięciem zmienia swoją pozycję w poziomie (w sposób losowy w lewo lub prawo - zgodnie z logiką zapisaną w kodzie JavaScript), Gdy kulka wyjedzie za lewą lub prawą krawędź - Gracz uzyskuje punkt - trzeba: uruchomić Zliczanie Punktów, kulka ponownie musi wrócić powyżej górnej krawędzi, aby rozpocząć swobodne spadanie, ale już w innym kolorze oraz z większą szybkością niż poprzednio, Gracza trzeba poinformować o liczbie punktów, Gracza trzeba poinformować o tym, że idzie mu dobrze, Gdy kulka spadnie poniżej dolnej krawędzi, Gracz nie uzyskuje punktu: kulka ponownie musi wrócić powyżej górnej krawędzi, aby rozpocząć spadanie, ale już w innym kolorze, Gracza trzeba poinformować o tym, że nie wykonał poprawnie kliknięć w spadający obiekt, granicznik - maksymalna liczba punktów - po uzyskaniu określonej, założonej przez programistę liczby punktów, kończy się gra: Gracza trzeba poinformować, że gra się zakończyła bo uzyskał określoną liczbę punktów, Na ekranie powinien znowu pojawić się napis START GAME, gdyby chciał Gracz zagrać ponownie. INNE ?? tutaj jest miejsce na dalszy rozwój gry - dla Ciebie oraz Twojej kreatywności :).

Swift 2 By Example. Create robust and extensible iOS apps using the advanced features of Swift 2
Giordano Scalzo
Swift is no longer the unripe language it was when launched by Apple at WWDC14, now it’s a powerful and ready-for-production programming language that has empowered most new released apps.Swift is a user-friendly language with a smooth learning curve; it is safe, robust, and really flexible.Swift 2 is more powerful than ever; it introduces new ways to solve old problems, more robust error handling, and a new programming paradigm that favours composition over inheritance.Swift 2 by Example is a fast-paced, practical guide to help you learn how to develop iOS apps using Swift. Through the development of seven different iOS apps and one server app, you’ll find out how to use either the right feature of the language or the right tool to solve a given problem.We begin by introducing you to the latest features of Swift 2, further kick-starting your app development journey by building a guessing game app, followed by a memory game. It doesn’t end there, with a few more apps in store for you: a to-do list, a beautiful weather app, two games: Flappy Swift and Cube Runner, and finally an ecommerce app to top everything off. By the end of the book, you’ll be able to build well-designed apps, effectively use AutoLayout, develop videogames, and build server apps.

Erik Azar, Mario Eguiluz Alebicto
Apple’s Swift language has expressive features that are familiar to those working with modern functional languages, but also provides backward support for Objective-C and Apple’s legacy frameworks. These features are attracting many new developers to start creating applications for OS X and iOS using Swift. Designing an application to scale while processing large amounts of data or provide fast and efficient searching can be complex, especially running on mobile devices with limited memory and bandwidth. Learning about best practices and knowing how to select the best data structure and algorithm in Swift is crucial to the success of your application and will help ensure your application is a success. That’s what this book will teach you.Starting at the beginning, this book will cover the basic data structures and Swift types, and introduce asymptotic analysis. You’ll learn about the standard library collections and bridging between Swift and Objective-C collections. You will see how to implement advanced data structures, sort algorithms, work with trees, advanced searching methods, use graphs, and performance and algorithm efficiency. You’ll also see how to choose the perfect algorithm for your problem.
