MetaCore

MetaCore 是一个基于 Panda3D 进行二次开发的 Unity-like 编辑器与引擎框架原型。

当前目标

  • 以 Panda3D 作为底层引擎与运行时基础
  • 以 Dear ImGui Docking 搭建 Unity-like 编辑器工作流
  • 使用 GameObject + Component 模型组织编辑器语义层
  • 先把 Hierarchy / Scene / Inspector / Project / Console 跑通
  • 在不破坏主架构的前提下，以模块化方式持续叠加功能

技术栈

  • C++20
  • CMake
  • vcpkg
  • Panda3D 1.10.16
  • glm
  • Dear ImGui Docking

目录结构

  • Source/MetaCoreFoundation：基础服务
  • Source/MetaCorePlatform：Panda3D 宿主窗口与输入采集
  • Source/MetaCoreScene：场景与对象模型
  • Source/MetaCoreRender：Panda3D 场景桥与显示区域驱动
  • Source/MetaCoreEditor：编辑器模块与 Unity-like 界面
  • Apps/MetaCoreEditor：编辑器程序入口
  • Apps/MetaCorePlayer：运行时壳层入口
  • tests：基础烟雾测试

构建

前提：

  • 已安装 vcpkg
  • 已设置环境变量 VCPKG_ROOT
  • Windows 环境可联网时，cmake configure 会自动准备 Panda3D 1.10.16 SDK
  • 如果已经本地安装 Panda3D，可设置环境变量 PANDA3D_ROOT
cmake --preset vs2022-debug
cmake --build --preset build-debug
ctest --preset test-debug

如果希望生成更适合分发的可执行文件，可使用：

cmake --preset vs2022-release
cmake --build --preset build-release

当前完成内容

  • Panda3D 单窗口宿主
  • ImGui Docking 编辑器外壳
  • Panda3D 中央场景 DisplayRegion
  • 网格、坐标轴、立方体绘制
  • Hierarchy 选择
  • Inspector 中编辑 Transform
  • Alt+左键 / 中键 / 滚轮 / F 相机交互
  • 模块注册接口与内置编辑器模块
