FollowTrack distance output?

[Celestar]

Is there any way telling FollowTrack to spit out the actual distance? Somehow the only response is '1' I get

I think that the enumproc you give to FollowTrack should save the best length found, in the void* data for example. At least, IIRC this is how it works for train pathfinding. Does this help?

rdf.maxtracklen will give you the best distance (by road) to the tile which is within rdf.mindist tiles of the destination.

So if the algorithm reaches the destination then rdf.mindist is 0 and rdf.maxtracklen will tell you how many road tiles have to be followed to get there.

These variables can be examined after the call to the inital FollowTrack.

I hope this makes sence

Somehow I ALWAYS get a distance of "1" as result, unless it finds no route.
