How to use a list and push/pop
|
Hi there I hope someone can help me out :)
I seem to have trouble with using lists. I'll short tell what I want to do, and what I've done sofar
btw im using Zmud6.40
..Ok what I want to do:
When i flee from a mob, it'll make me move two rooms. What I want to do is just walking back to the mob again, so if I flee north and west, I want to walk east and south to get back to the mob.
(That is when I have healed myself but that is not the problem atm)
..What I've done sofar:
I "pushed" the 2 directions into a list, I'm using push and a list because for example if I flee 'north' and 'west', I'm storing 'south' and 'east' in the list, when I want to go back to the mob I first have to "pop" 'east' and after that 'north'.
The things that I've done sofar is:
1. I created an empty variable FleeDir
2. when I flee east I push 'east' in the list with the command:
%push(@FleeDir, "east")
3. the same thing for north south west
4. with a test command I try to pop the two directions from the list with the commands:
%pop(FleeDir)
%pop(FleeDir)
5.and well uh it does nothing :P
Wonder what i'm doin wrong
I hope someone can help me out with this, thanks in advance! |

%functions() are NOT meant to be used as a command. They are ARGUMENTS for OTHER commands. Try something like:
#var dir %pop(FleeDir)
@dir
#var dir %pop(FleeDir)
@dir
There are other ways to do this, as well.. |

quote:
push
Syntax: %push(item,list)
Adds the item to the beginning of the list, and returns the new list.
Example:
List="a|b|c"
#SHOW %pop(List)
displays "a"
#SHOW @List
displays "b|c"
List=%push("a",@List)
display "a|b|c"
From the example, change the syntax of when you push.
#VAR FleeDir %push("east",@FleeDir)
Then you should be able to retrace with
%pop(FleeDir)
%pop(FleeDir)

Ooh I see the syntax of the pushing was wrong. I used the info of pushing from the support section on this site. Guess they tried to fool me ;) hehe
Wasn't able to try it last few days just got back, but it works now!
Thanks alot AzCowboy and TonDiening really appreciate it! |
