Easy Star JS Directional Conditions?

Any offers on how to use the directional conditions on the EasyStarJS pathfinding plugin?

I've been using the plugin now for a while with no issues but wanted to add a sort of rail system and need directional pathfinding but can figure out how to get it to work.

I've never used directional conditions, but it seems straightforward enough:

+ System: On start of layout
-> PF_Map: Begin adding directional conditions at 2,1
-> PF_Map: Add direction LEFT
-> PF_Map: End adding directional condition for the current tile

This way the tile at (2,1) can only be entered from the left.

I nearly tagged you in this as I knew you'd come up with a quick obvious answer as I've seen you in other threads using this plugin.

Works a treat thanks man.
