Apr 1, 2026April 2026 (2026-04) delivered core gameplay features, reliability improvements, and performance/quality enhancements across RyuichiroYoshida/September. Focus was on delivering tangible business value (player engagement and stability) while modernizing the architecture for remote control and analytics. Key feature delivery: - Cut-In System Enhancements: Timeline-based Cut-In playback with per-character cut-ins, input blocking during Cut-In, and timeline integration. Updated AnimationClipPlayer to support Timeline playback and ensured cut-ins align with skill duration and animation timing. - Ultimate Skill System Implementation: Initial Tanihira ultimate implemented with retrigger guard, ensuring a single, controlled activation and appropriate UI/input behavior during the sequence. - Timeline/Playable Controls Improvements: Enhanced control over Playable via Timeline, added basic PlayableGraph analytics/debug tooling, and robust handling when cameras are absent. - RPC/API Surface Enhancements: Exposed ControlState manipulation via RPC to enable remote-control integration and synchronization with host/client workflows. - Status and Effects Architecture Improvements: Introduced StatusEffectsContainer (Addressable integration) and prepared RPC synchronization for status effects; groundwork for scalable status/buff system. Major reliability and quality fixes: - Core Reliability & Event Handling: Addressed IObservable disposal leaks and eliminated duplicate state-transition invocations on both host and client. - Client/UI/Input Stability during ult and cut-ins: Fixed client input during ult, cleaned up UI/input behavior during sequences, and ensured camera switching logic runs locally. - Start/Preparation Timing and UI: Fixed start sequence timing, randomized start positions, and guaranteed timer/overlay visibility across preparation and start phases. - Data integrity and guards: Added comprehensive null checks, initialization guards, and safe handling for missing components (e.g., CutInAnimator) to prevent runtime exceptions. Overall impact and accomplishments: - Improved gameplay fidelity and stability, enabling a smoother player experience during cut-ins, ultimates, and sequence transitions. - Strengthened remote-control capabilities via RPC, enabling better tooling and potential QA/telemetry integrations. - Enhanced performance and scalability through Span-based calculations, reduced per-frame GetComponent calls, caching, and code-quality improvements. Technologies/skills demonstrated: - Unity Timeline/Playable API, AnimationClipPlayer, and Timeline-driven gameplay flows. - RPC/SOAP-like remote control interfaces and Addressables for status effects. - Performance optimization techniques (Span usage, caching, reduced allocations). - Architecture and code quality gains: null-safety guards, refactors, comments, namespace and folder restructuring, and robust testing hooks (logs and analytics).
