Palico 引擎：Swift 中基于金属的游戏引擎？

使用 Metal API 在 macOS 上实现游戏引擎。仍在开发中。目前，我正在研究功能更强大的实体-组件-系统MothECS？

Thanks to SwiftImGui by @ctreffs I am able to use ImGui in this application.

I forked the repository and wrapped ImGui v1.86 and added new OSX backend file. Related PRs:

• Update to 1.86 and update OSX backend (fix keyboard issue) #7
• Update ImGui 1.86-docking #8

? Future Development

Rendering:

• Add skybox
• Add shadow
• Support PBR
• Support deferred rendering (render pass has already been setup)

Model:

• Load 3D models
• Load textures in models
• Load animation

Other:

• Improve MothECS
• Integrate ImGuizmo
• Property/Inspector panel
• Game object selection
• Scene loading (yaml)
• Content browser (Asset Panel)
