Hard Graft


This map stuff has been really difficult. I’ve made a lot of progress, but it’s still not quite there yet.

My remaining tasks are:

  • Intelligently nullify tiles when applying centering
  • Fix bug where zooming causes map data to go out of sync if the zoom has caused a change of tile value
  • Implement separate async loading for peripheral, above and below tiles
    • Remove ‘fullyAsync’ from DownloadImageTask()
  • Implement directional async loading
    • If no direction (on start-up or zoom in/out), then attempt to async load ALL peripheral tiles
  • Apply lock on screen render if refresh already in progress
  • Fix auto-centre functionality
  • Get map data to fit GPS data
  • Possibly remove movement lock in onTouch()

That looks about right.
