Jul 1, 2026July 2026 performance summary for OpenTTD/OpenTTD: Key software delivery focused on editor clarity and rendering maintainability. Implemented Editor naming consistency by renaming GenerateRockyArea to PlaceRockyArea, reinforcing a unified codebase naming scheme without altering behavior. Completed a sprite rendering refactor to remove magic numbers by introducing lookup tables and refined density transitions; drawings function names were clarified, and sprite data structures were expanded with constants for slope counts and a snowy rock sprite array. Also fixed rocky ground placement issues in the Editor to reduce editor-related errors and improve UX. These changes collectively reduce technical debt, improve code readability, and set the stage for more scalable editor and rendering features, delivering tangible business value through predictable visuals and smoother development.

Jun 1, 2026June 2026 OpenTTD/OpenTTD monthly summary focused on order processing reliability and maintainability. Delivered an Order Review System Configuration Enum to centralize settings and improve readability, updated the vehicle order checking logic to exclude stopped vehicles based on the new configuration, and replaced magic numbers with descriptive enum types to ensure predictable behavior. Implemented a default setting to review orders excluding stopped vehicles (commit 3aa3113033381655bd577a90ce25d17261e6ffa7). This change reduces maintenance risk in the order processing pipeline and stabilizes gameplay behavior across configurations.
