O uso de diagramas para projeto de jogos de computador

Abstract

The development of digital games is a complex process that integrates design, programming, and storytelling. In this context, diagrams are essential to document, discuss, and validate behaviors: they enable the visualization of states and decisions (FSM/BT) and the modeling of resource flows and progression (Machinations), streamlining cross-team communication, analysis, and balancing. Model-Driven Engineering (MDE) leverages these artifacts as the core of the process, supporting automation and reuse. This work implements a graphical editor for the Machinations notation, featuring a library of essential symbols, connections with solid and dashed lines, sub-diagrams via “Select Mode,” per-item labels, and persistence in XML and JSON with preservation of visual properties. Visual validation included reproducing a reference diagram side by side with the original, demonstrating fidelity of shapes, styles, and semantics. The solution was validated on Windows with Qt and is oriented toward interoperability, paving the way for future integrations. Thus, the proposal aims to facilitate the creation and manipulation of diagrams, contributing to the application of MDE in game design and enabling advances in the field.
