PROFILE
Alberth
Alberth contributed extensively to the CorsixTH/CorsixTH repository, delivering features and fixes across animation, rendering, and localization systems. Over twelve months, he modernized animation pipelines, refactored map rendering for clarity and performance, and enhanced localization workflows, particularly for Dutch language support. Using C++, Lua, and CMake, Alberth improved code readability and maintainability by consolidating rendering layers, introducing robust error handling, and standardizing coordinate handling. His work included implementing a Sprite Visibility API, PNG screenshot support, and audio integration, while also addressing initialization order and regression issues. These efforts resulted in a more stable, maintainable, and feature-rich codebase.

Jan 1, 2026January 2026 monthly summary for CorsixTH/CorsixTH focusing on coordinate handling modernization and code readability improvements. Delivered a cohesive update to hit-testing and drawing consistency by adopting xy_pair across draw, hit-test, and animation, along with documentation clarifying the relationship between level_map::draw and level_map::hit_test. Implemented naming consistency enhancements to improve readability and maintainability, including renaming common parameters (pCanvas -> canvas, pWriter -> writer, pReader -> reader) and applying broader formatting improvements. The work reduces hit-test discrepancies, simplifies future refactors, and strengthens baseline quality for ongoing feature work.
