I'm trying to use AddToMapper("north","south") but it is adding the directions in this format to my Mapper:

(/north)

reverse

(south/)

when I try to backtrack the route - it just executes empty lines.

You realise this is nothing to do with the graphical mapper, right?

Anyway, I tested it. I typed:


AddToMapper("north","south")


And then verified with:


print (GetMappingString ())


And it printed:


(north/south) 


As expected.

Thanks for the reply Nick,

To add some more substance I'm trying to modify the Slow_Speedwalk plugin to add steps from that plugin to the auto-Mapper (so I can retrace steps).

The issue I'm coming into is that "walk_lines" in the plugin, although recognized as a type string isn't cooperating with any of my code trying to read it as such (that is why the example above was giving empty directions).

What I would like to achieve is the following in the Slow_Speedwalk.xml plugin.

Quote:

-- send the speedwalk
reverse_dirs = {north = "south", south = "north", west = "east", east = "west"}

Send (walk_line)

AddToMapper(walk_line, reverse_dirs[walk_line])


I was wrong in thinking AddtoMapper was broken, it is my understanding of lua that is, as always - not up to standard :)

As a side note, is there a way to edit the "standard directions" inside MUSHclient. I know I can add a special step via DoMapperSpecial but is there a way to the NWES directions to include (in/out) or should I just use an alias to achieve that?

It's hard coded and I'm reluctant to change it at this stage. You can do it in Lua, for example from elsewhere on this forum:



local valid_direction = {
  n = "n",
  s = "s",
  e = "e",
  w = "w",
  u = "u",
  d = "d",
  ne = "ne",
  sw = "sw",
  nw = "nw",
  se = "se",
  north = "n",
  south = "s",
  east = "e",
  west = "w",
  up = "u",
  down = "d",
  northeast = "ne",
  northwest = "nw",
  southeast = "se",
  southwest = "sw",
  ['in'] = "in",
  out = "out",
  }  -- end of valid_direction
  
-- for calculating the way back
local inverse_direction = {
  n = "s",
  s = "n",
  e = "w",
  w = "e",
  u = "d",
  d = "u",
  ne = "sw",
  sw = "ne",
  nw = "se",
  se = "nw",
  ['in'] = "out",
  out = "in",
  }  -- end of inverse_direction


First you can "normalise" a direction by using the first table (so "up" becomes "u") and then use the second table to get the inverse direction.


"In" is done differently because it is a Lua keyword.
