Development of computer game in augmented reality

U ovom diplomskom radu obrađena je 3D mobilna igra sa proširenom stvarnošću korištenjem programa Unity Engine i Vuforia programskog alata. Glavni cilj igre je obraniti kip koji sadrži energiju života, pri čemu je potrebno poraziti sve neprijatelje (kosture) i njihovog glavnog vođu (Diamond Lord). Igrač igra iz prve perspektive, pri čemu može koristit četiri vrste oružja (pištolj, automatska puška, strojnica i snajper). Igračeve kretnje su definirane fizičkim pomicanjem mobilnog uređaja (korištenjem ugrađenog akcelerometara, žiroskopa) u odnosu na metu (Image Target) koja je definirana korištenjem Vuforija alata. Ovaj alat je implementiran kao paket u Unity Editoru. Definirana scena se prikazuje u odnosu na prepoznatu metu (2D sliku) u prostoru i na taj način je ostvarena interakcija između stvarnog i virtualnog svijeta. Unatoč implementacije Vuforija alata, korištene su skripte za upravljanje objektima koje su pisane u C# programskom jeziku. Grafičko, korisničko sučelje izrađeno je u GIMP 2 programu, dok su za izradu scene korišteni modeli koji su preuzeti sa stranice besplatnog sadržaja, kao i melodije te zvučni efekti. Prilikom izrade animacija korišten je ugrađeni sustav Unityja, Animator. U svrhu spremanja rezultata u lokalnu bazu korišten je JSON format, a implementacija je ostvarena korištenjem SimpleJSON plugina. U igri ukupno postoje dvije scene. Prva predstavlja glavni izbornik u kojem igrač može vidjeti trenutno ostvarene rezultate, podesiti postavke i započeti s igrom. Druga scena je nivo koji se učitava kada je prepoznata meta (Image Target) u kojoj ishod može biti pobjeda ili poraz.In this final paper 3D augmented reality mobile game was processed. It was made combining Unity Engine and Vuforia software. The main purpose of the game is to defend sculpture which contains energy of life, while player needs to defeat all enemies (skeletons) and their boss (Diamond Lord). The player plays from the first perspective and can use four types of weapons (pistol, automatic gun, machine gun and sniper). The player movements are defined by moving mobile phone physically (using embedded accelerometer, gyroscope) in relation to the target (Image Target) which is defined by Vuforia software tool. This tool is implemented into Unity Editor as package. Defined scene is rendered after target (2D image) is recognized in the physical surrounding and that is the way of accomplishing interaction between real and virtual world. Despise using Vuforia tool, bunch of scripts were used for controlling objects which are coded in C# programming language. Graphics, user interface was made by using GIMP 2 software, while for making scenes the models were used. The models were downloaded from free-content sites, same as melodies and sound effects. During process of creating animations, embedded system of Unity, Animator was used. In order to save the results to the local base, JSON format was used, and implementation was accomplished using the SimpleJSON plugin. There are two scenes in the game. The first scene represents the main menu in which player can see current achieved results, setup settings and start with the game. The second scene represents level which is loaded, rendered when target (Image Target) is recognized. The outcome of level can be victory or defeat
