Implements basic flow-field pathfinding in the engine.

  • Field types
    • Cost field
    • Integration field
    • Flow field
  • Pathfinding
    • Portal node graph search with A*
    • Line Of Sight pass
    • Cost Integration pass
    • Flow Field Pass
  • Documentation
  • Demo 0: Flow field show case
  • Demo 1: Grid with portals/sector based search
    • Interactive setting of path

What's missing:

  • Cost stamps
  • Caching flow field results
  • Better heuristics cost for portal node graph search
  • Pass LOS/wavefront flags through portal
  • Integration into game simulation (next PR)
