Compilation

# Native
./setup.sh
./run.sh minimal/native_test

# Web

TODO

• Showstoppers

  • The various TODOs
    • Throw error when setting no mesh
    • Make mesh color optional
    • Patching ECS entities at runtime (mesh.color?)
    • Queried mouse position doesn't match up with window position
    • Camera matrix is only sent to the shader once per frame, and afaik right here it's already out of date by 1 frame
    • Remove all remaining functionality from Image and Texture besides loading them
    • Entire engine breaks if BSGE isn't declared
    • Can't use separate cameras for separate buffers(?)
    • Buffer:bind(function() end)
    • mesh_render is a mess
    • VSync controls (ai generated mess)
    • text is stretched
    • window controls (ai generated mess)
    • Don't hardcode js identifiers for bsge canvas and container
    • Gizmo drawing to secondary framebuffers
    • Optimize link times for web
    • Different build types (Release, Debug)
      • Minimize final web build size
  • Datamodel format
    • Scene explorer
      • Child traversal
  • Editor
    • Scene creation format for a datamodel
  • Clean the engine up
    • Inconsistent function calling convention
    • Inconsistent structure
    • Don't use source built libs in native build
  • Audio

• Other

  • UI Rendering hierarchy + how it's gonna interact with 3D objects
    • New component for UI objects that has helpers for positioning
    • Maybe similiar to Unity rendering?
  • Raytracer BVH
  • UTF-8 Text Rendering
