TODO

  • add waypoint repository
  • add waypoint ID, make sure owerwriting wayponits works the way it should
  • save Byte order in metadata
  • save biome colors. Loading and displaying worlds should not have any dependency on the game itself.
  • make migrations tests
  • more decoupling on all fronts
  • create encoders and decoders (mostly for tiles but might be required for some other stuff as well)
  • alert the user if a crash log has been detected. "Can we send it?" "yes"/"no"/"show"
  • make sure I/O work is really done on I/O dispatcher with infinite threads. Remember that I/O work is blocking so if we run I/O work on a coroutine that uses a dispatcher with 8 threads, one of these 8 threads will be blocked, it's not just a coroutine that will be suspended this way.
    • If all threads are parked and that's the reason the app doesn't do much work, it won't show on the flamechart
  • either use more of @RequireOptIn as a form of encapsulation or actually make multiple modules in the project
  • NIO RandomAccessFile might be of use for some of the data manipulations I do

Tiles management

  • loaders should use sharedFlows or some other observable type to broadcast the information

  • So it means tiles should be subscribed to. They can be returned more than once.

    • If the tile is not loaded, it should be loaded then returned
    • If the tile is loaded, it should be returned instantly, update should be scheduled and then again an updated version should be returned
    • Tiles can be returned again whenever they're updated

  • in order to get loaded tile, sent a request to loader and then observe the result

  • there could be alternative way to load the tile using a suspend method if it's only required once. Then it after loading the loader should call the continuation and unsubscribe to the tile

  • event handling

    • the frontend requests to load the data but needs to subscribe only to the tiles that it has requested to load or keep loaded
    • after receiving the event that the tile is loaded, the updater can now update the tile but

Design choices

withLock implementation found in UpdateQueue and MapAreaAccess - These are operations that can be accessed from multiple threads but none of them are crucial do be finished quickly. The most important thing here is to not waste any CPU time constantly checking whether the concurrent implementation of some data structure can be used. That's why I'm using a delay in a suspend function and using regular, non-synchronized implementations of data structures.
