Update
Add a combo option "Exact" in "Action:Get moving path", "Action:Get moving path by UID". Set it to "nearest" could get moving path to nearest target tile. It will always return a path from start tile to nearest target tile.
BTW, Here is a demo -- Sternhalma (Capx)
- deep green chess is the chess to move
- click any blue tile to put/remove green chess
- yellow tiles are move-able
