Comparison of Blueprint Visual Scripting and C++ Programming Languages when Developing a Computer Game in Unreal Engine Environment

Razvojem sve većeg broja programskih proizvoda za razvoj video igara performanse istih postaju sve bitnije kako bi razvojna okruženja ostala konkurentna na tržištu. Unreal Engine 4 (razvojno okruženje) jedna je od platformi za razvoj računalnih igara i za razliku od većine razvojnih okruženja, sadrži 2 programska jezika unutar softvera koji se značajno razlikuju po procesu izrade, tijeku rada, brzini i kvaliteti izvedbe konačne igre. Cilj rada je usporedba programskih jezika C++ i Blueprint u Unreal 4 u razvojnom okruženju. U svrhu usporedbe izrađene su dvije računalne igre koje se ne razlikuju izgledom i rasporedom razina, već je jedina razlika u pozadini, odnosno u programskim jezicima koji pokreću mehanike igara. Kroz rad je dokumentiran i uspoređen razvoj igara u oba programska jezika, te su analizirane prednosti i nedostatci finalnih igara i uspoređene su njihove performanse. Nakon analize broja slika u sekundi i utjecaja broja objekata na performanse igara u oba programska jezika vidljivo je da C++ programski jezik ima bolje performanse u finalnoj igri, a istovremeno je razvoj igre u ovom programskom jeziku brži i u mnogim slučajevima i jednostavan u odnosu na Blueprint programski jezik.With the development and a growing number of software products for the development of video games, their performance is becoming increasingly important in order for game engines to remain competitive in the market. Unreal Engine 4 (game engine) is one of the platforms for computer game development and unlike most development environments, it contains 2 programming languages within the software that are significantly different from each other. The aim of this thesis is to compare programming languages C ++ and Blueprint in the Unreal Engine 4 environment. For the purpose of comparison, two computer games were made that look identical visually and do not differ in layout of levels, the only difference is in the programming languages that drive the mechanics of the game. The comparison of programming languages contains the advantages of both languages and a comparison of the performance of the finished games. After analyzing the number of frames per second and the influence of the number and type of objects on the performance of games for both programming languages, C ++ programming language has better performance in the final game, and at the same time the game development in this programming language is in the programming language
