Over four months, Seongrae Han contributed to the NbcampUnreal/1st-Team2-Final-Project repository, building and refining core gameplay systems, UI, and multiplayer features using Unreal Engine, C++, and Blueprint scripting. Han engineered a robust radar system, overhauled save/load mechanics with UI integration, and implemented a data-driven shop and mission subsystem, focusing on maintainability and player experience. He introduced localization support for Korean and English, improved audio and rendering subsystems, and delivered defensive programming to reduce crash scenarios. Han’s work demonstrated depth in system design, code refactoring, and debugging, resulting in a more stable, scalable, and user-friendly game architecture.
August 2025 performance summary for NbcampUnreal/1st-Team2-Final-Project. The month focused on stabilizing core gameplay systems and expanding audience reach. Key initiatives included Radar System Reliability Improvements to ensure consistent radar detection and proper exclusion of ignored actors, and Localization System Integration to provide basic Korean and English support via a LocalizationSubsystem and translation constants integrated into UI and interactables. These efforts directly improve player experience, reduce debugging time in radar-related edge cases, and lay groundwork for broader localization in future releases.

July 2025: Implemented two major feature areas (Radar System Enhancements; Save/Load System Overhaul with UI) and a suite of robustness fixes. Delivered a 2D radar integration with mesh/material management and a fix to prevent radar widgets from persisting across map transitions. Overhauled the save/load subsystem with SaveDataSubsystem and UI controls, plus safeguards to prevent transitions during save/load. Strengthened stability with comprehensive crash-prevention checks (CloseShop guards, logout handling, inventory state fixes, null-pointer guards on tool attach/detach). Result: enhanced user experience, reliable game progress, and reduced crash scenarios across sessions, with demonstrable business value through safer sessions and smoother user flows.

June 2025 Monthly Summary – NbcampUnreal/1st-Team2-Final-Project (2025-06) Overview: Delivered a strong blend of core gameplay system improvements, UI/UX enhancements, and hardening for stability and deployment. Focused on mission orchestration, radar and HUD clarity, data-driven content, and robust multiplayer behavior. Results translate to smoother player experiences, faster iteration for designers, and a more stable build for wider release. Key features delivered (business value and technical impact): - Mission Condition System Enhancements: added mission condition type settings and mission subsystem event Bind/Unbind to enable dynamic, configurable mission flows and faster tuning (commits 931f9815f4...; dd0b0534e1...). - Refactor Mission Subsystem: comprehensive refactor of Mission Subsystem and related components to improve maintainability, readability, and extensibility (commit c900f20109...). - EUnitId BlueprintType Addition: BlueprintType specialization for EUnitId to empower designers with data binding in Unreal Editor (commit 440baf52d6...). - Radar/Comms and Visual UX improvements: added Radar Emissive Control to mitigate bloom and later Radar Display Cleanup (commits b3806a7a20...; f36c256d...); included compass drone display enhancements and related UI polish (commits 3369eac2...; 5126d747... for HUD widget). - EventTrigger and FogController enhancements: separated BeginOverlap/EndOverlap, updated Triggerable interface, and introduced FogController to improve world interaction logic and visuals (commit f2ec6d1132...). - HUD: Mission icons widget: introduced a HUD widget that presents mission icons and data for at-a-glance status, improving UX and decision speed (commit 5126d747ad...). - Async loading and startup reliability: added AsyncLoadingScreen plugin to streamline client loading and address perceived startup delays (commit 5e4251ca2a...). - Data-driven content: creation of data tables to support game configuration and content-driven design (commit 72902d6e73...). - Shop and gameplay enhancements: introduced shop upgrade features and related UX improvements to support progression pacing (commit 969987115f...). - Phase UI and Level travel enhancements: Phase UI changes and LevelTraveler move conditions—tighter feedback loops and UX consistency (commit 5dfe9567a9...). Major bugs fixed (stability, reliability, and platform readiness): - Spawner bugs: resolved multiple spawner-related issues to stabilize enemy/world population (commit 635f9123a3...). - Initialization and code completeness: fixed missing initialization logic and missing CreateNewId code paths (commits ae05c9e7d8...; c435969b7b...). - Multiplayer and session stability: fixed client join crash and related networking edge cases (a1bf34f90e...; 9003343429f...). - Gameplay/flow crash and edge-case fixes: phase completion results window issue and final-phase crash fixes (11edaecff0d...); additional crash repairs for drones/compass view and map transitions. - Defense and anti-cheat hardening: GetMoney cheat introduction containment and ServerTravel defenses to prevent server-side abuse (commit 9dd3289078...). - Packaging and build reliability: addressed shipping build bugs and packaging issues to ensure release readiness (commits bd34f3b...; 82b210d8...; 310e685f...). - Miscellaneous bug fixes: radar defense logic, pathfinding point positions, portal collisions, and various usability fixes (several commits, e.g., 41cfb92e...). Overall impact and accomplishments: - Stability and quality: Significantly improved stability for client/server gameplay, reduced crash surfaces, and hardened release packaging, enabling smoother player experiences and lower post-release hotfixes. - UX and designer empowerment: UI widgets (HUD mission icons, compass display improvements), phase UI, and data-driven design enable faster iteration and clearer player guidance. - System maturity: Subsystem refactors and new features (Mission Subsystem, EventTrigger/FogController, EUnitId BlueprintType) position the project for scalable content and easier long-term maintenance. - Performance and reliability: Radar optimization and sound system hardening contributed to calmer gameplay visuals and more stable audio across modes. Technologies/skills demonstrated: - Unreal Engine architecture: Mission Subsystem, EventTrigger, FogController, BlueprintType, data tables, and UI widgets. - UI/UX and designer tooling: HUD widgets, compass displays, and phase UI integrations for improved player guidance. - System design and clean code practices: extensive refactors, code cleanup, and comments for future maintainability. - Performance and deployment: AsyncLoadingScreen plugin, packaging fixes, and shipping build hardening to improve release readiness. - Sound and gameplay polish: Sound subsystem enhancements and careful tuning across phases and shop interactions. Notes: - This month included a broad set of PRs across features and bug fixes; where possible, commits are listed for traceability. - Next quarter focus areas: further harden multiplayer edge cases, enhance data-driven tuning, and iterate on the new HUD/compass UX based on QA feedback.
