speedwalk to closest room in a string list
|
I have mapped a favorite mud of mine and Have a string list variable called @Healerlist that contains the room vnums of healers on the mud I play.
I would like to be able to run an the alias Goheal to #walk to the closest room in the list @Healerlist
I'm assuming I should have to use some sort of #if statement to accomplish this task
any help is appreciated |

Ah, a fun one. I've done a couple things similar, let me see if I can recall how...
It would be something like this, but I don't guarantee this will work without testing:
[edited to correct the code a bit]
| Code: |
#LOCAL $pathlength $curpathlength $closest
$curpathlength = 99999999999
#FORALL @healerlist {
$pathlength = %numitems(%pathexpand(%pathfrom(,%i)))
#IF ($pathlength < $curpathlength) {
$closest = %i
$curpathlength = $pathlength
}
}
#show Closest healer room is: $closest, $pathlength rooms away

I have this exact feature, you will need the following alias for this to function correctly.
| Code: |
| #ALIAS mark {#VAR MarkedRoom %roomvnum} |
Here is my script for running to the closest healer.
| Code: |
#UNVAR Healers
mark
{#ADDKEY Healers %len(%pathexpand(%pathfrom(,healer1))) healer1} {}
{#ADDKEY Healers %len(%pathexpand(%pathfrom(,healer2))) healer2} {}
#SORT Healers numeric |
The above adds healer1 and healer2 (they are room nicknames) to a variable and sorts them by length.
Therefore you just need to run to the following, and it will run to the closest healer.
| Code: |
| #WALK %item(Healers,1) |
Hope this helps, this is the code cut down a lot. I have features that allow me to disable
healers from the list if they are exhausted etc... |

One note, though it wouldn't matter to this script, using %len(%pathexpand(some path)) returns the length of the path, in addition to all of the separator characters (pipes} between the steps, so %len(%pathexpand(3ne)) would return 7, rather than 4. %numitems(%pathexpand(some path)) will give the correct number of steps.

Door commands are included in paths given via mapper commands/functions. This will throw off your step count.
