Motor de videojuegos en C++ sobre SFML

Abstract

[EN] The purpose of this end-of-degree project report is to explain some general concepts about video game program- ming, game engines and their utility, and how X-GSD is built around some of these ideas, including: types of game loop and simulation, resource management, scene graph, entity-component system, events and basic physics. Nowadays, game engines have become very popular and a fundamental part for many game developers. De- spite their bene ts, this tendency comes with costs: As the most popular engines are proprietary, game developers become reliant on closed third-party software, which could lead |among others| to a deadlock of their projects in the worst case. This and more against-reasons regard- ing popularity of proprietary and big game engines are discussed along this work. X-GSD stands for Cross-platform Game Skeleton (Data- Driven), a basic data-driven C++ game engine built upon SFML1. It is a totally free and open basic game engine which aims to solve some of the problems of proprietary game engines, or being a starting point for custom solu- tions. It can also serve as an academic example of how to start building the core of a game, or a game engine.
