Simple Travel Script Porting
|
| Code: |
#class {travel} {kill}
#class {travel} {open}
#var travel 0
#function {revdir}
{
#switch {"%1"}
{
#case {"north"} {#return south};
#case {"east"} {#return west};
#case {"south"} {#return north};
#case {"west"} {#return east};
#case {"up"} {#return down};
#case {"down"} {#return up}
}
}
#function {longdir}
{
#switch {"%1"}
{
#case {"n"} {#return north};
#case {"e"} {#return east};
#case {"s"} {#return south};
#case {"w"} {#return west};
#case {"u"} {#return up};
#case {"d"} {#return down}
}
}
#function {shortdir}
{
#switch {"%1"}
{
#case {"north"} {#return n};
#case {"east"} {#return e};
#case {"south"} {#return s};
#case {"west"} {#return w};
#case {"up"} {#return u};
#case {"down"} {#return d}
}
}
#function {finddir}
{
#if {"%1" != "%2"}
{
#return %2
}
{
#return %3
}
}
#alias {travel}
{
#if {$travel}
{
#var travel 0;
#showme <118>You stop traveling.
}
{
#var travel 1;
#var lastdir @longdir{%0};
#var lastdir @revdir{$lastdir};
%0
}
}
#act {[Exits: %1]}
{
#if {$travel}
{
#if {"%1" != "%* %*"}
{
#var travel 0;
}
#regex {%1} {%* %* %*}
{
#var travel 0;
}
#regex {%1} {%* %*}
{
#var newdir @finddir{$lastdir;&1;&2};
#showme <118>You travel $newdir.;
#var lastdir @revdir{$newdir};
@shortdir{$newdir}
}
}
}
{1}

Fairly simple. Was just looking to port it to CMUD. I don't want to seem as if I'm looking for a handout. I've done done research and can accomplish this, but I'm sure this is a more effective way. I'm still trying to familiarize myself with CMUDs *MANY* functions. (I.E. %revdir is already available I see)
Thanks in advance. |

The %reversedir function works like this:
%reversedir(north) = s
%reversedir(north, 1) = south
%reversedir(%reversedir(north)) = n
Something like this would check single word commands, test them for being a direction, and if so, sets the direction you came from:
#ONINPUT {^(%w)$} {#IF (%reversedir(%1)) {lastDir=%reversedir(%1, 1)}}
Not entirely sure what else you are trying to do without an explanation.
#TR {~[Exits: (*)~]} {does something} |

Ah sorry. It's basically a traveling script for two-way roads (rooms with only two exits)
You use alias travel (direction) and it continues until it reaches an intersection.
It basically works as is with minor changes. I just didn't know if there was a more... elegant... way to accomplish this.
Also probably worth mentioning that $ is the variable symbol and @ denotes a function for anyone trying to understand this. |

that's what I thought
This should turn the mud output into a string list, remove your @lastdir from the list, and then check to make sure there is only one item in the list left before trying to send that as a command
#TR {~[Exits: (*)~]} {
$exits=%replace(%replace(%replace(%1, ", and ", "|"), " and ", "|"), ", ", "|")
#DELITEM $exits @lastDir
#IF (%numitems($exits)=1) {$exits}
}
in CMUD $var referances local variables, @var reverences regular variables, %func() for the predefined functions, and @func() for custom functions
There is no need for custom functions for this in CMUD though. |

| Code: |
#TR {~[Exits: (*)~]}
{
#if {$traveling}
{
$exits = %replace(%replace(%replace(%1,"[",""),"]","")," ","|");
#DELITEM $exits @lastDir;
#if (%numitems($exits)=1)
{
$exits;
#show %ansi(red)You travel $exits;
#var lastDir %reversedir($exits);
}
{
#var traveling 0;
#show %ansi(red)You stop traveling to pick up new directions.;
}
}
}

That's what I have so far. I'll test it when I get a chance. |

Firing but not compiling? |

I don't see any clear code problems so I am going to guess it is a formatting problem. CMud's parser is much more picky than a compiler for a programming language like C++, but even more advanced parsers require certain to tokens to be grouped in certain ways. I believe CMud requires the open brace to be on the same line as the code it relates to.
These formattings have always worked well:
| Code: |
#IF (condition) {
code
} {
code
}
#IF (condition) {code} {code}
|

Yes, that fixes it.
Everything works as anticipated.
Thank you sir! |
