May 1, 2025May 2025 (p4sstime/p4ss) delivered substantial configurability, gameplay integrity, and UX improvements across the project. The work focused on introducing ConVar-driven controls for core gameplay parameters, refining respawn logic to handle edge cases, and enhancing UI feedback to players and spectators. This set of changes reduces manual tuning, improves match reliability, and enables faster iteration on game tuning while maintaining compatibility across builds and modes. Scope and outcomes: - Configurable suicide cooldown via ConVar sv_limit_suicide_rate, replacing the hardcoded 5-second limiter; documentation hints improved for mouseover hints. Notable commits: cf182545f8e7f2e17c7abfacf35061bfa1b8895b; 3b93227369615c7912c9e4e9c83dd8ee5402a318. - Respawn mechanics improvements and corrections: refined timing by accounting for spec_freeze and restored proper respawn state when necessary, with revert of unnecessary file changes where applicable. Notable commits: 1ca927389feb1132ef040201ae5656dcfd2f7271; 0cd5896e7d6a9e4c2008f6cceab0e1475c77fcae. - HUD: dynamic critical health threshold via ConVar and client behavior updates to reflect threshold changes. Notable commits: 248239333176d9acc07c7970cf77094d7d7360bd; e820e038c8caa3813c4079828be6ff5cf580acff. - Pause round timer when ball is out of play to reflect active gameplay; commit: 4c7c0d813c0aa8c405f5e0e75e806eeb03ea90dc. - Holiday controls enabled in all builds by removing development flag from holiday convar; commit: 7d3921c62a38ba10424a4cb5e7a24a68efcdc3f0. - Additional hardening: preserve killstreaks on resupply; fix spectator UI to show team status to spectators; restore original player flag handling with a proxy to mask irrelevant bits, ensuring stability across edge cases. These are supported by commits: 6904b1c6fec9ebc01212e07f42ac8787ddcf27b0; f7c8a62604b7810153aae0d63a3187505f844944; 49f35e32a722ddd9f1811578acf14b5c2e06a380; 0fe7dd10d9b0e0a479924a90fff5dc78a18a3908.

Apr 1, 2025April 2025 highlights for p4sstime/p4ss. The team delivered core security hardening and stability improvements, refined configuration and fallbacks for Passtime mode, improved respawn responsiveness, and enhanced server-side prediction accuracy, while maintaining strong repository hygiene. Deliverables and outcomes align with reducing attack surface, preventing client-server inconsistencies, and enhancing player experience and reliability across releases. Key features delivered: - Passtime mode refactor and configuration cleanup: Rename ConVars from p4ss_ to pf_; introduce pf_nolock to control automatic pass target locking; refine pass target logic to respect pf_nolock. (coding discipline, configurable behavior, reduced confusion) - Respawn timing precision: Display respawn time as floating-point with one decimal place and allow immediate respawns when possible, improving responsiveness and user perception of fairness. - Maintenance and hygiene: Update .gitignore to exclude VSCode task configuration files, reducing local-dev config leakage. Major bugs fixed: - Security hardening: disable risky player commands (e.g., cyoa_pda_open) to prevent contracker exploits; alignment with patch p4sstime/p4ss#124. - Player name handling and safety: fix maximum player name length by accounting for null terminator; aligns with Steam limits to prevent buffer overflows. - Server prediction accuracy: increase precision of server m_flDucktime float to resolve prediction errors; note LuaJIT subproject added to support performance improvements. Overall impact and accomplishments: - Reduced security risk and exploitation surface in contracker workflows, improving game integrity and trust with players. - Increased stability and safety through careful limit handling and input sanitation; reduced potential crashes due to buffer overflows. - Improved player experience with more accurate respawn timing and stable pass target logic, contributing to fair and responsive gameplay. - Enhanced performance and reliability with higher-precision server timing and LuaJIT groundwork, enabling smoother multiplayer experiences. Technologies/skills demonstrated: - C/C++-level refactoring and ConVar management, careful naming conventions, and feature toggles (pf_ naming, pf_nolock). - Floating-point time representation and death/respawn flow adjustments for accuracy. - Performance optimization and tooling integration (LuaJIT subproject) and improved server-side precision. - Version-control hygiene and PR hygiene with thoughtful commits and documentation in commit messages.

Feb 1, 2025February 2025 monthly summary for the p4sstime/p4ss repository. Key features delivered include Caber energy restoration on impulse 101 to align Caber with other energy weapons, and the addition of an IsCaber virtual function to reliably identify Caber weapons and ensure consistent behavior. A new balance control was introduced via ConVar tf_selfblast_resist_on_enemy_hit to tune self-damage when explosives hit enemies, enabling granular balance adjustments. Repository hygiene improvements focused on configuration readability and dev workflow safety, including reformatted autoexec.cfg and updated .gitignore rules to exclude custom developer configurations while preserving necessary ignores. No explicit major bugs were reported; where relevant, edge-case interactions (e.g., energy restoration parity) were addressed to improve stability. Overall impact includes improved gameplay balance, easier maintenance, and faster onboarding for developers. Technologies/skills demonstrated include C++, virtual functions, ConVars, configuration management, and Git hygiene.
