João Manita contributed to the GameDevTecnico/cubos and cubos-demo repositories by developing core gameplay and physics features using C++ and the Entity Component System architecture. He engineered systems such as a dynamic balloon spawning pipeline, a day-night cycle with time-of-day management, and a distance constraint system for the physics engine, each designed to improve simulation realism and gameplay flexibility. His work included refactoring collision detection to support multiple contact points, enhancing both stability and future extensibility. João also authored technical documentation in Markdown and CMake, supporting onboarding and feature adoption, and addressed edge-case bugs to ensure predictable, maintainable game behavior.

June 2025 Monthly Summary for GameDevTecnico/cubos-blog: Delivered essential developer-facing documentation and contributor visibility enhancements that improve feature adoption and content credibility. The main deliverables were: 1) Distance Physics Constraint Documentation (version 0.7) detailing how to add and customize distance/range constraints between two physics bodies, with examples for rigid and range-based constraints and configurable anchors. 2) João Manita Blog Contributor Profile added to the author directory, including name, role (Physics Team Member), and academic background. No major bugs fixed this month; all work focused on documentation and contributor onboarding. This effort accelerates downstream development, reduces onboarding time, and strengthens trust with readers and contributors.

April 2025 — Key physics engine enhancement delivered in the cubos repo, delivering a Distance Constraint System to enable fixed or ranged distances between entities. The work included a new component, solver logic, and a practical sample scene to showcase multiple use cases. This feature establishes a foundation for more deterministic and stable simulations (e.g., tethered objects, ranged interactions) and accelerates future constraint work.
