Oonoyouji
Over thirteen months, OonoYouji developed ONEngine, a modular C++ and C# game engine, focusing on scalable architecture, real-time rendering, and robust editor tooling. Their work encompassed building an ECS-based entity system, scene management with JSON serialization, and a cross-language scripting interface using Mono. They engineered features such as terrain editing, prefab workflows, and a data-driven asset pipeline, integrating ImGui for UI and DirectX 12 for graphics. By refactoring core systems, implementing GUID-based asset management, and automating build processes with Premake, OonoYouji improved runtime stability, iteration speed, and asset reliability, delivering a maintainable foundation for complex game development.

Aug 1, 2025August 2025 ONEngine monthly summary: Delivered core engine enhancements, stability improvements, and enabling tooling for faster development and reliable releases. The month focused on feature delivery that improves runtime efficiency, authoring capabilities, and cross-language integration, while fixing release-critical issues to reduce risk in production. Key features delivered: - Component usage tracking: Added IDs to components to determine whether they are used, enabling targeted cleanup and usage analytics. - Skybox retrieval optimization and SceneIO cleanup: Switched to array-based Skybox component retrieval and removed unused old SceneIO functions to simplify the codebase and improve load paths. - Camera system enhancements: Introduced camera component support, inspector-driven camera addition, and JSON persistence; added IO validation to ensure camera operations function across builds. - ECSGroup refactor and per-scene management: Replaced prior ECS with ECSGroup, introduced per-scene ECSGroup maps and updated only active groups for performance. - Script variables persistence and JSON scripting: Persist script variables on object creation and enable applying saved values via JSON for faster iteration and consistent state restoration. Major bugs fixed: - Environment reflection normals normalization bug fixed to ensure correct shading and bloom during reflections. - Release/build reliability fixes: guard against release build errors, ensure DEBUG_MODE header inclusion, and add release build verification checks. - Runtime start and cleanup issues: fix camera/runtime startup bugs and ensure consistent script startup without errors. Overall impact and accomplishments: - Improved runtime performance and rendering stability through optimized Skybox retrieval, ECSGroup updates, and terrain/script integration work. - Enabled faster iteration and reliable builds with development and release workflow improvements, JSON-based scripting, and inspector-driven tooling. - Strengthened cross-language integrity between C++, C#, and Mono scripting, reducing synchronization gaps and release risk. Technologies/skills demonstrated: - C++, C#, ECS design patterns (ECSGroup, per-scene ECS), compute shaders, and texture-based terrain IO. - Editor tooling with inspector integration, JSON serialization, and ImGui-based UI aspects. - Release engineering, build configuration (develop and release), and runtime verification practices.

Mar 1, 2025In 2025-03, the ONEngine team delivered a breadth of features across UI, rendering, and gameplay, while cleaning up the codebase and hardening runtime stability. Key outcomes include a robust ImGui-based debugging UI with dual-window support, modular window management, and localization; a stabilized input model when multiple windows are open; and a more polished visual presentation with start/end textures and an asset/hierarchy explorer. The render pipeline was extended with a render-texture system, multi-render-target support, UAV textures, and compute-shader integration, enabling more complex post-processing and scene rendering. Core gameplay features include block placement with type-based coloring, static block sizing, provisional player movement, stage-bound movement, and type-restricted block movement, laying groundwork for more complex puzzle/physics interactions. The project structure was reworked for maintainability, with cleanup of unused textures and refined release checks. These efforts reduce debug time, enable richer QA, and accelerate feature delivery going forward.

Nov 1, 2024In Nov 2024, ONEngine shipped a robust set of gameplay systems, physics stability improvements, and foundational framework work that collectively raise quality, debugability, and business value. Key features delivered include a gauge-style HP display for player health, debug visualization for start/end points, and collider object displays, plus extensive physics and collision work (capsule orientation improvements; simplified collision checks; and full capsule-capsule and capsule-sphere detection). The camera system was expanded with core tracking/follow/lock-on behaviors and targeting logic, including rotation limits and smoothing to reduce jitter. Architectural work established a core game framework, moved scene management into the engine layer with a scene factory, and added an MT4_01_01 verification task to strengthen build/test coverage. Rendering and tooling improvements include a lighting-enabled mesh renderer, UV transform/texture handling improvements, and reliable number rendering with zero-digit handling. These changes improve stability, debugging efficiency, and readiness for production while enabling richer gameplay experiences.
