Hi!
I was thinking along these lines :
he gets stuck halfway on the rail
You can't just say "Move ahead and check whether the rail is still beneath your feet, if not, move back" ^^'
every rail ends at some point -
2nd line : why not?
If your block is at the end of the line he should be able to turn back. If he's
really stuck he wont be able to move back.
Do you have a debug panel that follows the vectors (they are global)
and the other path nodes? (PANEL* and digits)
