path Clear

path clear removes every path block (blocks), every path avoid area (avoid) or every path link (links), on every facet. learned forgets the places where a walk had a step refused, which the walker otherwise avoids for a while (see path go). Without a word, or with all, it removes all four. The options of path set are not touched.

Starting the script again clears them too. #PathState is ok, or error: … for an unknown word.

Example

path link 1500 1600 0 1700 1600 0
path clear links                 ; forget the link again
halt
