Sep 1, 2025September 2025 — RPTools/maptool monthly summary: Delivered a set of stability and performance improvements across rendering, HTML handling, and editor tooling, with a focus on reliability, maintainability, and business value. Highlights include rendering correctness and performance improvements in ZoneRenderer; safer HTML rendering without legacy bridges; improved campaign editing robustness; codebase simplifications and hygiene updates; and enhanced developer telemetry through configurable performance metrics. Key features delivered: - ZoneRenderer rendering correctness and performance improvements: fix token clipping to visible cell areas, unify visibility calculations via a new getVisibility usage, introduce precomputed visibility-related areas for Fog of War, stop timers reliably, decouple ZoneRenderer logic via a ViewModel, and adjust clipping methods and performance thresholds for ZoneRenderer. Updated call sites to ZoneView#getVisibility(PlayerView). - HTML rendering reliability enhancements: remove Java bridge and base URL injection parameters; default to processing raw HTML for consistent behavior; apply fixHTML to HTML5 content to maintain cachelib behavior. - LibGDX renderer removal and cleanup: removed LibGDX renderer and related components to simplify the codebase with minimal user-facing impact. - CodeTimer: configurable reporting units for performance metrics to improve readability and customization. - MacroEditorDialog: code hygiene and encapsulation improvements – privatize fields and remove stray commented-out code. - Campaign editing stability: guard against missing MacroButtonProperties during campaign edits to prevent crashes and improve user experience. Major bugs fixed: - Timer and visibility logic stabilizations in ZoneRenderer (preCheck timer, hardFow timer, clip handling) and microsecond-level threshold adjustments to improve rendering reliability. - Robust campaign editing when MacroButtonProperties are missing to avoid crashes. - HTML content handling edge cases to ensure consistent parsing and caching behavior. Overall impact and accomplishments: - Improved rendering accuracy and performance with lower CPU overhead for ZoneRenderer, leading to smoother user experiences in map rendering. - Higher reliability and stability in campaign editing and HTML content handling, reducing user-reported crashes and edge-case issues. - Cleaner, more maintainable codebase with fewer dead paths thanks to LibGDX removal and targeted refactors, enabling faster future iterations. - Enhanced visibility into performance metrics through CodeTimer with configurable reporting units, supporting better data-driven optimizations. Technologies/skills demonstrated: - Java/LibGDX codebase maintenance, performance tuning, and refactoring (ViewModel decoupling, ZoneRenderer visibility API usage). - HTML parsing robustness without bridge dependencies and base URL manipulation. - Defensive programming and UI stability improvements for editor tooling (MacroEditorDialog, MacroButton handling). - Code hygiene practices and lifecycle improvements for long-term maintainability.
