9a88505ee88bc8e5b33702f180dccec4c18dbe4a
refactor + wip: changed to a more "abstract" component querying system, allowing for other developers to create their own components. also shuffled the code, and now got the commonMain working (to a documentable stage).
todo:
- implement jvmMain functions, implement JNI rust code and test to see if physics is working
- if physics is working:
- implement nativeLibMain and native rust code
- if physics is NOT working:
- fix up PhysicsState in rust and kotlin and see what the issue is, then resolve.
- fix up magna-carta to support new system
will i hit my deadline (basic physics working by new years)??? hopefully so...
Signature present but could not be verified.
