Implementação de Dead Reckoning para mitigar o efeito da latência em jogos multiplayer

Abstract

Multiplayer functionality in games is becoming very common. In turn, it increases the complexity of game development projects and introduces new challenges. One of the challenges is characterized by the fact the internet is an unreliable network. A specific problem to be solved in a multiplayer game development project is lag. An online game with no lag tolerance can be detrimental to the players’ experience quality. There are known solutions for common communication problems between networked applications. This paper implements dead reckoning, a solution to network fallibility by extrapolation of the game entities’ position. The implementation was written in C# language and uses Unity game engine to simulate a game with multiplayer features so the developed solution can be applied to it. Along with the solution, tests were also implemented to help measure it’s performance.
