View list of data type meanings


This takes a speedwalk as an argument and removes any backtracks from it.

For example: "4n 2s" would be converted to "2n".

A side-effect of this routine is that comments will be removed from speedwalks, and "reverse direction hints" will also be removed. eg. "(open door/close door) {comment}" would be converted to "(open door)".

It will also join directions where possible, eg. "n n n" would become "3n"

Note: Available in version 3.48 onwards.

VBscript example
world.note world.RemoveBacktracks("4n 2s")
Jscript example
world.note(world.RemoveBacktracks("4n 2s"));
PerlScript example
$world->note($world->RemoveBacktracks("4n 2s"));
Python example
world.note(world.RemoveBacktracks("4n 2s"))
Lua example
Note(RemoveBacktracks("4n 2s"))
Returns The supplied string, with the backtracks removed as described above.
If there is an error in the speed walk string then the first character of the returned string will be an asterisk ("*"), and the rest will be an English error message.
Introduced in version 3.48
