Is it possible to use A*PP when trying to find a path for an agent that takes more than one cell (2x1 or 2x2), without creating separate grids?
This discussed a bit in this tutorial in the current beta version: https://www.arongranberg.com/astar/documentation/dev_4_1_14_3886c2bf/multipleagenttypes.html
see the section on “Other approaches for grid graphs”.
