description: "XCEngine 处于早期构建阶段，核心基础设施正在逐步完善"
context: |
  XCEngine 是一个正在开发中的游戏引擎项目，当前版本 0.1.0 专注于建立核心基础设施。
  核心模块（Core、Math、Containers、Memory）已基本完成，提供了游戏引擎所需的基础构建块。
  
  渲染系统（RHI）已完成双后端支持（D3D12 和 OpenGL），但高级渲染特性（如光线追踪、
  网格着色器）尚未实现。
  
  资源管理系统（Resources）已具备完整的加载框架，支持异步加载、缓存和依赖管理，
  但仅支持基础格式（纹理、网格、着色器）。
  
  缺少的子系统：物理系统、脚本系统、实体组件系统（ECS）、音频系统、UI 系统。
  这些将在后续迭代中逐步添加。
