Implementing multiplayer core features for GameMaker Studio 2 using Node.js : game area instances and simulation layer

Abstract

The objective of the thesis was to implement multiplayer core features for an existing game prototype developed on GameMaker Studio 2. The game prototype, which had a single-player mode, was targeted to support multiplayer and networking. Node.js offered a solid JavaScript runtime with technologies and modules that helped to design and build a network topology and a client-server integration to the current game prototype.

The project and development were executed by the author alone. The work utilized common project management conventions and methods, including game designing, software requirements specification, agile development, kanban boards like Trello, version control tools like Git, and continuous testing. The tools and languages used included GameMaker Studio 2 with GML, Node.js written in JavaScript and run on Visual Studio Code, a group of NPM third-party modules, and several popular free project management tools.

As a result of the thesis, an integration between GameMaker Studio 2 and Node.js server was achieved. The implementation utilized network elements and technologies such as UDP communication protocol, a hybrid server model, and a custom protocol layer. With added multiplayer mode support, the game prototype has the potential to scale and include more gameplay elements adapted to networking in future development. It was also proved that GameMaker Studio 2 has potential and tools for multiplayer development with the help of external technologies.
