I found this over at TBA and thought it was useful.  We probably have the help file in 4D as well, but I'm too lazy to look right now and I know I've needed this info before.  So, for everyone else:

Text Variable Fields

   These fields pertain to any variable that contains a string of text. These
are often the variables, such as %speech%, which are provided to a trigger, but
can also be variables that have been created by the trigger, such as
%room.north%

When using field - The variable returns
 
strlen     - Returns the number of characters in the string.
trim       - Returns the string without any leading or trailing whitespace.
             This is used to trim extra spaces from the beginning or end of a
             string.
car        - Returns the first word of the string. For %text%="this is the
             string"; %text.car% will yield "this".
cdr        - Returns all but the first word of the string, trimmed. For %text%=
             "this is the string"; %text.cdr% will yield "is the string".
contains() - Used to check if a string contains the subfield text.
mudcommand - Returns the mud command the string is shorthand for. Used to make
             sure the command you react to is the one you want: For %text%="o"
             %text.mudcommand% will yield "open".
charat     - set new variable %text/var.charat(index)% i.e. set phrase testing,
             set var1 %phrase.charat(2)% now %var1% == e

Name: 'Napalm bomb - 317',  VNum: [  337], RNum: [  258]
Trigger Intended Assignment: Objects
Trigger Type: Command , Numeric Arg: 2, Arg list: nap
Commands:
if napalm /= %cmd%
  if %actor.fighting% && !%arg%
    set arg %actor.fighting%
  end
  if !%arg%
    %send% %actor% Throw it at Who?
    halt
  end
  if %arg.room% != %actor.room%
    %send% %actor% Throw it at who?
    halt
  end
  %send% %actor% You throw the napalm at %arg.name%, it strikes %arg.himher% and shatters, exploding into a ball of fire consuming %arg.himher% completely.
  %echoaround% %actor% %actor.name% throws the napalm at %arg.name%. It shatters and explodes into a ball of fire consuming %arg.himher%.
%asound% A large explosion is heard close by.
  set stunned %arg.hitp%
  %damage% %arg% %stunned%
  wait 5 sec
  %echoaround% %arg% %arg.name% collapses to the ground as the flames die down. %arg.heshe% seems to still be alive, but barely.
End

** I found this script interesting for a couple of reasons.  First, the ability to set an arg when it isn't explicitly given and the fact you can find out the himher on that arg.  Also, who doesn't like a Napalm bomb? **

Name: 'Mob Act - 98 Teleporter Give',  VNum: [  398], RNum: [  265]
Trigger Intended Assignment: Mobiles
Trigger Type: Act , Numeric Arg: 0, Arg list: has entered the game.
Commands:
if !(%actor.inventory(82)%)
  wait 1s
  say You are not prepared to travel these realms to their fullest.
  wait 1s
  say Maybe I can help you.
  %load% obj 82
  give teleporter %actor.name%
*could actor carry the weight?
  if !%actor.inventory(82)%
  drop teleporter
  end
  wait 2s
  say With this you may teleport to areas that may not be accessible in
any other way.
  wait 2 sec
  say HELP AREAS
end

** I chose this script because I've always wondered what an ACT script actually was – since there never seems to be much detail behind any of them anywhere.  Looking at the Arg list, I can then assume that this script reacts to any time it sees “has entered the game”

Just a short trigger to keep this up as often as possible.

Name: 'Mob Greet direction',  VNum: [  302], RNum: [  223]
Trigger Intended Assignment: Mobiles
Trigger Type: Greet , Numeric Arg: 20, Arg list: None
Commands:
* By Rumble of The Builder Academy    tbamud.com 9091
if %actor.is_pc%
  wait 1 sec
  if %direction% == none
    * if the character popped in (word of recall) this will be hit
    say Where did YOU come from, %actor.name%?
  else
    say Hello, %actor.name%, how are things to the %direction%?
  end
end

Well, we do, of course. Who said we didn't have pirates - I mean everything? :)

There is goldpanning in one of the Sutter zones, I forgot which one.
Probably set up in a different way, but still goldpanning.

It has been a while since I posted so, here's another one.  I grabbed it a little too late for Valentines day, but it would have rocked if I'd seen it earlier.  Maybe next year.  Hope I haven't posted this yet.  I'm too lazy to go through all the old posts to see.

Trigger of the Day:

A sliding puzzle, which can be modified for any m*n grid, and for any tile description. It also has a visually impaired toggle. I think this is interesting because it:

1. shows how to extract the first and second words the player types after entering a command and
2. shows what %%var%% and %%%var%%% do

Set up: Here's (part of) what the player sees when he looks at the object.

"puzzle board" - See the current layout of the board
"puzzle move up" - Move a tile up into the empty space.
"puzzle move down" - Move a tile down into the empty space.
"puzzle move left" - Move a tile left into the empty space.
"puzzle move right" - Move a tile right into the empty space.
"puzzle rules" - See the rules of this puzzle.
"puzzle toggle" - Toggle for visually impaired.

and below is the trigger! If anyone has any suggestions on how to improve this, it's much appreciated :)

Trigger of the .... something
« Reply #40 on: July 02, 2014, 12:07:47 pm »
This will be a post out of three posts, introducing functions, in order to achieve the goal of replacing characters of a sentence.

For example, given a string (of words, not sausages):

It was the best of times, it was the worst of times

and you want to replace the second letter of the tenth word by a u, eg to

It was the best of times, it was the wurst of times

how can you do so?

While this doesn't seem very useful from the sound of it, inventive scripters can script games (eg a game of battleship), by doing something like:

set grid .......... .......... .......... .......... .......... .......... .......... .......... .......... ..........

and if they want to fire at a position, and denote the fired position as an *, then the challenge is to convert 

.......... .......... .......... .......... .......... .......... .......... .......... .......... ..........

into

.......... .......... .......... .......... .......... .......... ...*...... .......... .......... ..........

for example.

Also, the best part about functions is that they can be reused again and again, and they just need to be called in the script. One idea is to have a zone full of (useful) functions, so all builders can call them (without taking up trigger vnums in their own zone), plus it gives some kind of signal to coders :P about which functions are useful to be added into the dg code.

As an aside, functions are very useful for doing the same things over and over again. If you have a main quest in a zone where the quest reward is only given when six side quests are done, you don't want to write the same script six times - to check if the main quest reward should be given when any of the six side quests have been completed.

So today's trigger of the day will focus on counting the number of "objects / words / items" in a variable. We will use this function in the next two posts to achieve our goal.

Input: findnumwords
Output: num

findnumwords will be the variable we are interested in finding the number of words of, and num the number of words.

Here is the function.

Code: [Select]
Name: 'function to check num words',  VNum: [33785], RNum: [ 2182]
Trigger Intended Assignment: Objects
Trigger Type: FUNCTION, Numeric Arg: 100, Arg list: None
Commands:
if !%findnumwords%
  %echo% We do not have any inputs!
  %echo% The input variable should be named findnumwords
  halt
endif
set stopping_criteria 1
set start 1
while %stopping_criteria% != stop
  extract num %start% %findnumwords%
  if !%num%
    eval num %start% - 1
    set stopping_criteria stop
  endif
  eval start %start% + 1
done

So to use the function, we just need to do this:

Code: [Select]
set findnumwords I want to be a pirate
function 33785
%echo% We have %num% of words

Of course, we can always do

Code: [Select]
set findnumwords %actor.thisvariable%
etc

The next post will be functions on replacing words in a sentence, and replacing characters in a word, before building up to the final post!

Here is part 2, and it will be on function triggers to replace a word in a sentence, as well as to replace a character in a word.

Both function triggers are similar in execution, so hopefully it counts as one trigger of the day.

Some possibilities of these triggers (along with some modifications):

1. Make a mob rhyme with you (could replace / add on characters to the last word you say)
2. Dynamic passwords to go through a zone: (eg the second word of the password is always the day of the week)
3. Script a lot of (multi-player) games which rely on grids.

Anyway, here are these triggers!

The first trigger replaces a word in a sentence, as shown below.

Code: [Select]
Name: 'Replace word in sentence',  VNum: [33783], RNum: [ 2181]
Trigger Intended Assignment: Objects
Trigger Type: FUNCTION, Numeric Arg: 100, Arg list: None
Commands:
if !%sentence%
  %echo% Need a sentence to replace words.
  halt
endif

If !%word%
  %echo% Need a word to replace a word in the sentence.
  halt
endif

if !%replacenum%
  %echo% Need the position of the word to replace
  halt
endif

*First, find out how long the sentence is
*Recall our previous function took in the input findnumwords

set findnumwords %sentence%
function 33785

*We now have %num%, which is the length of the sentence
*Now we build up the sentence from the original sentence

if %replacenum% > 1
  extract newsentence 1 %sentence%
  set h 2
  while %h% < %replacenum%
    extract buildsentence %h% %sentence%
    set newsentence %newsentence% %buildsentence%
    eval h %h% + 1
  done
  set newsentence %newsentence% %word%
  eval h %h% + 1
elseif %replacenum% == 1
  set newsentence %word%
  set h 2
endif
while %h% <= %num%
  extract buildsentence %h% %sentence%
  set newsentence %newsentence% %buildsentence%
  eval h %h% + 1
done

This trigger takes in the inputs: sentence, replacenum, word.

sentence - Should be set to the sentence you are looking at
replacenum - The position number of the word you want to replace
word - The new word

The trigger gives the output: newsentence

So for example, suppose you have the phrase:

I am at the bottom of the world

and you want to replace the fifth word with the word top.

Then, you would do something like:

Code: [Select]
set sentence I am at the bottom of the world.
set word top
set replacenum 5
function 33783
%echo% %newsentence%

and you get your new sentence to be: I am at the top of the world

The second trigger replaces a character in a word.

Code: [Select]
Name: 'Replace character in word',  VNum: [33782], RNum: [ 2180]
Trigger Intended Assignment: Objects
Trigger Type: FUNCTION, Numeric Arg: 100, Arg list: None
Commands:

if !%word%
  %echo% Need a word to replace characters.
  halt
endif

If !%character%
  %echo% Need a character to replace a character in the sentence.
  halt
endif

if !%replacenum%
  %echo% Need the position of the word to replace
  halt
endif


set len %word.strlen%

*We now have %len%, which is the length of the word
*Now we build up the word from the original word

if %replacenum% > 1
  dg_letter newword 1 %word%
  set h 2
  while %h% < %replacenum%
    dg_letter buildword %h% %word%
    set newword %newword%%buildword%
    eval h %h% + 1
  done
  set newword %newword%%character%
  eval h %h% + 1
elseif %replacenum% == 1
  set newword %character%
  set h 2
endif
while %h% <= %len%
  dg_letter buildword %h% %word%
  set newword %newword%%buildword%
  eval h %h% + 1
done

This trigger takes in the following inputs: word, replacenum, character.

word - Should be set to the word you are looking at
replacenum - The position number of the character you want to replace
character - The new character

The trigger gives the output: newword

So for example, if you have the word

Candyland

and want something a bit more R rated, you could do the following:

Code: [Select]
set word Candyland
set character R
set replacenum 1
function 33782
%echo% newword

I got this script from a visitor from TBA that was asked to help out on another zone.  I've left in all of her comments on it even before the script because it all sounded like valuable information when dealing with the script.  This should be able to be adapted for any cooking anyone wants to do.  So, from Parnassus:

I've tried this on TBA and it seems to work.  First, you need to decide where to put it.  If you put it on a room, such as a kitchen,  or a mob, such as a cooking teacher, Numeric Arg is 100.  If you put it on something like a pot or a skillet, Numeric Arg is 2 (in inventory)  or a heatsource, such as a stove should be 4 (in the same room).

Next, set the vnums.  Each ingredient and each food needs a vnum.  On TBA, I just used various foods that seemed similar, just for experimenting with.

If it works the way you wanted it, create the items.  I've set up recipes for various dishes with an explanation of the bonus of each dish.  Wisdom is missing since I couldn't think of anything but the dishes I have probably don't seem connected either, such as Mario's mushrooms for a constitutional boost.  I'd have liked a nice dish of brains but I don't think that's an ingredient on 4d.  Of course though, the trigger is extremely expandable by inserting new ingredients in one section and recipes in two sections.

If you need any changes, let me know.  If it isn't what you were looking for at all, let me know that too.  I can think of places to use it so it won't be wasted if you can't use it.  One change might be to add a list of missing ingredients.  I was thinking of that but it would add about 3 to 5 lines to each recipe as well as another 5 to 10 lines in the error section.

If you try to /fi this, it won't format.  I think this is because of the mix of ifs/ends and switches/breaks.  I've tried to pre-format it in sections for easier reading.

A nice way of repeating (mostly) similar stuff. For example, suppose you have a zone that echoes similar stuff like:

The flight to <random country> leaves at Gate <random number>. You could do something like switching cases. But a cooler way would be to do something like

Code: [Select]
set vec1 Heathrow Moscow Edinburgh Frankfurt Dublin Paris Newark LAX Minneapolis Georgia Hell Amsterdam Sydney Salzburg Bratislava Japan Toronto
eval randnum1 %random.20%
eval randnum2 %random.17%
extract place %randnum2% %vec1%  *we're extracting a random city from the above vector
%echo% The flight to %place% leaves from Gate %randnum2%.
Tada! And you don't need to create 17 different cases for a minor change!

What happens if we want to script a quest which went like this:

1. Give me grapes from Ancient Greece
2. Give me a laser gun
3. Give me a game

Well, most quests are specific, eg: "Give me grapes from Imbros, give me a 4D laser gun, give me a Battleship game." But what if we wanted to make sure ALL possible items are valid? Well, we could add in if statements. However, this gets tricky when more and more zones are built, and thus more items are valid?

We show how we can do this with one quest array, and how builders can copy and paste the entire script below and adapt it to any such quest.

Let the questarray be an array with 4 variables. First 3 are yes/no variables, and the last denoting whether the quest has been completed before or not.

Here are examples of some arrays

Code: [Select]
* Example of quest not done
myquestvar: no no no incomplete
* Example of quest where first item and third item has been found, but player hasn't completed it
myquestvar: yes no yes incomplete
* Example of quest where player has completed it at least once before, and is trying again and he only gave the second item
myquestvar: no yes no complete

Now, here is the grand script.

Code: [Select]
**** CANDIDATE LIST
**** This quest accepts multiple possible items, so update this list
**** accordingly. For example, if someone typos that another item
**** might fit, then add in the new vnum to the array. This is the only
**** change you need! YEAH!

**** Number of different items needed
set numquests 3   

**** Item 1
set questitem1 12345 4205 14673
set msg1 Thanks for giving me questitem1

**** Item 2
set questitem2 1222 5070 5323 64325
set msg2 Thanks for giving me item 2!
   
**** Item 3
set questitem3 503 703
set msg3 Thanks buddy

*** This is it! Edit the above part when more items get added - the below will do everything for you
*** Msg is optional, could add more stuff, but you get the gist.

** We're going to loop through this

** Note: This is not the most efficient way of doing so, but
** we have relatively few quest items. If you want to re-use this code
** for substantially more vnums, one way is to order the arrays in
** increasing order, and do a binary search for appropriate vnums

if %actor.varexists(myquestvar)%
  set questvars %actor.myquestvar%
  eval statusnum %numquests% + 1
  extract status %statusnum% %questvars%
  set curritem %object.vnum%
 
  *First loop through all arrays. numquests quest items, so numquests arrays
  set arrnum 0
  while %arrnum% < %numquests%
    eval arrnum %arrnum% + 1
    extract itemarray %arrnum% %questvars%
    set item%arrnum% %itemarray%
    * read this array
   
    * Note: We have to eval this, and not set, otherwise it'll be a string
    eval currarray %%questitem%arrnum%%%
   
    * So for example, if arrnum was 1, then
    * currarray would be set to 12345 4205 14673 (value of questitem1)
    * %echo% %currarray%   
    * uncomment above to check!
   
    * Now, find the length of this array
    set stopping_criteria 1
    set start 1
    while %stopping_criteria% != stop
      extract num %start% %currarray%
      if !%num%
        eval num %start% - 1
        set stopping_criteria stop
      endif
      eval start %start% + 1
    done
   
    * We've got the length of the array stored as %num%
    * Now, loop through each item in the array
   
    set j 0
   
    while %j% < %num%
      eval j %j% + 1
      extract itemtocheck %j% %currarray%
     
      * Finally, we check if it's the same item as what we want
      if %curritem% == %itemtocheck%
        wait 1s
        mjunk %object%
        * Perfect, let's set the variable to yes
        set item%arrnum% yes
       
        * Again, eval and not set
        eval currmsg %%msg%arrnum%%%
        say %currmsg%
       
        * Set a variable gotcorrectitem because we want the mob to respond
        * if none of the items were right
        set gotcorrectitem yes   
      endif
     
    done           
  done
 
  * At the end of the loop, we need to do two things
  * If no right item was given, then
 
  if !%gotcorrectitem%
    wait 1
    say No, no, that's all wrong.
    say Try to get it right next time.
    mjunk %object%
    wait 2
    emo waves his hands and what you handed him disappears!
    halt
  endif
 
  * Now, we have to check if all 3 were achieved, and concurrently update
  * the new variable. Create loop to rebuild array, and count how many
  * correct items
 
  * Create new variable resetquest in case player gets all 3
 
  set j 0
  set counter 0
 
  while %j% < %numquests%
    eval j %j% + 1
    eval curritem %%item%j%%%
   
    if %curritem% == yes
      eval counter %counter% + 1
    endif
   
    if %j% == 1
      set myquestvar %curritem%
      set resetquest no
    else
      set myquestvar %myquestvar% %curritem%
      set resetquest %resetquest% no
    endif     
  done
 
 
  if %counter% < %numquests%
    * Can't set status to incomplete, but need to use previous
    * one, because player might have done quest before
    set myquestvar %myquestvar% %status%
  else
    * Note, got to reset quest, but must flag complete
    set myquestvar %resetquest% complete
    * Set complete quest sequence here

    %send% %actor% I reward thee!
  endif
  * Finally, don't forget to remote this
  remote myquestvar %actor.id%
else
  * If no questflag, giving should not do anything
  halt
endif
