Abstract

U ovom su radu analizirani izazovi koji se pojavljuju prilikom razvoja umreženih višekorisničkih igara u virtualnoj stvarnosti te su proučene najčešće mrežne arhitekture i protokoli za prijenos podataka korišteni prilikom njihova razvoja. Na temelju snimljenog mrežnog prometa analizirana je mrežna arhitektura postojeće umrežene višekorisničke aplikacije u virtualnoj stvarnosti.

U alatu Unity razvijena su dva prototipa višekorisničke umrežene igre u virtualnoj stvarnosti: kooperativni prototip i prototip igrač protiv igrača. Kooperativni prototip temelji se na međusobnoj suradnji igrača koji zajednički rješavaju jednostavni matematički zadatak. Prototip igrač protiv igrača temelji se na međusobnoj borbi igrača koji pokušavaju poraziti jedan drugoga gađajući se objektima. Za umrežavanje izrađenih aplikacija korišten je paket Photon Unity Networking.

Osmišljeno je i provedeno ispitivanje čiji je cilj utvrditi kako mrežno kašnjenje kod višekorisničkih umreženih igara temeljenih na virtualnoj stvarnosti utječe na iskustvenu kvalitetu korisnika i njegovu želju za nastavkom ili prekidom igre, te na vrijeme trajanja i ishod igre. Ispitivanje je provedeno na primjeru igre Serious Sam VR: The Last Hope, a u njemu su sudjelovale 24 osobe.

Abstract (english)

This thesis analyzes the challenging aspects of developing a networked multiplayer game in Virtual Reality (VR) and explores the most commonly used network architectures and networking protocols. An existing networked multiplayer VR game has been analyzed based on the captured network traffic.

Two networked multiplayer VR game prototypes were created based on different types of gameplay: cooperative and Player vs. Player. The cooperative prototype requires players to work together to solve a simple mathematic problem. The Player vs. Player prototype requires players to fight against each other by aiming objects at each other’s avatars. The game prototypes were made in Unity, using the Photon Unity Networking package.

A study was designed to assess the effects of networking delay on the quality of experience for networked multiplayer VR games. The participants were asked to rate their perceived quality of experience and decide whether they would continue playing the game under the given circumstances. The duration and the outcome of the game were also noted. The study was conducted on 24 participants using the game Serious Sam VR: The Last Hope.
