Zugg Software :: View topic - Alright, running through a string... couple of purposes

Wizard Joined: 26 Mar 2008 Posts: 1547

This was mentioned before, but I wanted to make a whole thread for it. I really want to understand this for the many effects it can have. That is, I want to know how to take a string not in list format and have it run through each word.

For a bit more complexity, it can stop running through words once a certain thing happens.

For even more complexity, it can remove words that will obviously do nothing for it, particularly articles like "a" and "the"

Some examples...

Awhile back I wanted to do some complex stuff with a trigger set that would record what I was wearing currently, and the last item I was wearing. This would be neat for various purposes, the example I have however is merely one.

There is a place in my game in which you will go deaf on a certain event if not wearing an item called "a pair of beeswax ear plugs". However nice they are, that's their only purpose and I only wear them when I go to the place. I'm often made to go there for quests, a lot of actions for which I've automated. I'd like to have it automatically wear the ear plugs. But that's the easy part. The hard part is having the proper head piece being worn after I turn in the quest. I could make one for my current head piece, but then I would have to remember to change it whenever I got something new. Instead, I would like the client to remember what I was last wearing so that when I turn in the quest, it can put that on instead.

This isn't the head piece, but I don't actually have a good one right now. So here's another example of my point:

You stop using some bull elephant leather gloves.

some bull elephant leather gloves
^ is the short name for the item

Some bull elephant leather gloves lie here.
^ is the long name for the item

'bull elephant leather gloves'
^ are the keyword for them

The keywords are what is important, however, when I remove the piece, it captures the short. As you can see, for many items, the short and keywords are very similar, so if I caught "some bull elephant leather gloves", excluded "some" and ran through each word it would be reequipped. To avoid the wrong items being worn, I would actually like the algorithm to run like this:

Try whole string -> Try first word in string -> Try second word in string -> ... -> ...

For that first bit of complexity, when the item is worn, for efficiency, it would be nice if it stopped right there and didn't continue. For instance, when I put the gloves back on:

You wear some bull elephant leather gloves on your hands.

When that line came back up, after it sent the whole string "bull elephant leather gloves" (since some would be removed), that should match, the action should happen. But instead of then trying "bull", "elephant", "leather", "gloves", it would be nicer if it just took the wearing line and stopped.

So that's about all that I can think of. I'm looking for help in setting this up, and explanations so I can understand what's going on.

Your looking to try a brute force approach when you need finesse. What you want to do is capture the keyword when it is input with the wear or remove command, and record the item it relates to. Then you can coordinate a putting something back on.

Alternately you could use the sneaky method that should work for the mud codebase you are on. Try this at the command line:

wear bees
wear 1
You stop using a elephant leather helmet.
You wear a pair of beeswax ear plugs on your head.

Not wear 1, wear 1. The . is very important, at least in most code bases.

Chamenas you sure are confusing. Why would you try and "wear bull" or "wear elephant"? Are you going to wear a bull on your head? Those are just descriptions not the actual item.

a pair of bull elephant leather gloves

GLOVES are the item. It's just like when you refer to any item, thing, or person. If I have an ornate steel rapier, I don't try "wield ornate" I do "wield rapier", otherwise the Mud will come back and say "What are you retarded? I don't see that item!" or some nonsense. So why can't you just wear helmet or wear earplugs? For that matter, don't they have item numbers so you can just wear #####?

I understand what he means, Oldguy.
He has a list of keywords that he can refer to the item by.
By short name, he means short description. By long name he actually means the dropped description (going by IRE crafting anyway) and by keyword, he means keywordS. Some of our (IRE) items have multiple keywords too. longcoat, coat. Pants, trousers. Etc. His mud just has more of them, and he would like to have a single trigger that wears what he was wearing before, regardless of what it was.
He doesn't want to have the item number of it stored in a variable, because it probably changes often.
He doesn't want to refer to it by 'gloves' first off, because 'elephant' is more specific, while 'gloves' might refer to several types in his inventory.

The first thing I would do, Chamenas, is turn the string into a stringlist. I'm going to use the old text format for displaying settings because I'm not confident with creating the xml from memory yet.

I'll play around with it later, class is about to start and I should focus on that. Razz

Well whatever. That's not the same thing. Glad it's all worked out though.

Wizard Joined: 26 Mar 2008 Posts: 1547

Well I don't know if it has, still have to test it. In response to what you said, the most unique identifier that any item has is all of its keywords at once, so, for the gloves:

'bull elephant leather gloves'

that string would be the most unique ID

Another similar item might be:

'bull elephant leather helmet'

using bull, elephant, or leather will mean it checks for the first item with that keyword (you can type 2.leather, 3.leather, etc... in order to get other things with the same keyword.

In theory gloves and helmet are unique ids in this scenario, but not always. The most unique ID is the entire string name. The problem is that the short does not always have all of the keywords.

Right gotcha. It's just most muds I have played don't let you use something like that.

Hm. So you don't really want to try each word individually, you want to try the whole string and then if it fails start removing words that from it until it works? Beginning of course with words that are most likely to be non-keywords, such as 'some'?

I'm heading out for a few hours, but while I'm off if you can, please help by confirming this, or if I still have it wrong, correcting me. Then I'll have another shot at it.

At this stage the basis of what I suggested should still work, the only difference is figuring out how and what to remove from the short description.

I have two more requests, actually:

1st: the message when you "You stop using a elephant leather helmet."
Is the underlined part always the full list of keywords that form the most unique ID?

2nd: If the answer to the first is no, please post a list of all the short/wear/remove descs you can find in your inventory, as we need to try and figure out a pattern to it. If there is a patern, then the solution is fairly easy. If there is no pattern, then its a matter of creating a big list of non-keywords and checking for all of them every time.

Why don't I just quote my first response since this part got ignored.

Shhh! Let us catch up to you at our own pace... gracefully. No one likes an 'I told you so' Sad

To be honest, it didn't get entirely ignored: I used your advice in my suggestion, and captured the keywords from that trigger as you suggested, with:
#TR {You stop using a (*).} {keywords={%replace(%1," ","|")}}

I just didn't understand that he can do "wear <entire keyword string>" hence turning the string into a list of keywords.
So how about:

#TRIGGER {^You stop using a (*).} {#var bruteitem %1;#var bruteforce %replace(%1," ","|")}
#ALIAS wearold {#T+ "WearTrig";wear %replace(@bruteforce,"|"," ")}
#TRIGGER "WearTrig" {^You do not have that item.} {#CALL %pop(bruteforce);wear %replace(@bruteforce,"|"," ")}
#TRIGGER {^You wear *} {#addkey wearequip @bruteitem @bruteforce;bruteforce="";bruteitem="";#T- "WearTrig"}

Tested, and I'm sure you get the idea. What it's going to do is take the variable in "You stop using a (*)" and places it untouched in the bruteitem variable and modified to a stinglist in the bruteforce variable. Then, when you're ready to wear it again, type "wearold" and it'll run wear @bruteforce. If that fails, it'll remove the first word in the list and try again with the string. Example:

You stop using a some elephant bull gloves. -> "some elephant bull gloves" is stored into bruteitem. some|elephant|bull|gloves is stored into bruteforce.

You type "wearold", and it activates the WearTrig. It'll first try to wear "some elephant bull gloves." If that fails, it'll return whatever message (in this case, "You do not have that item.") Bruteforce then becomes elephant|bull|gloves. Next, it'll try to wear elephant bull gloves. This works, so a database is created called "wearequip." In that database, the "some elephant bull gloves" will have a value of "elephant bull gloves." You can use this database in the future to recognize what you took off and what the keywords are to wearing it again.

Hope this helps, and if you need more understanding, just let me know.

Well, I tried using your suggestions to edit what I already have just for the recording part. But not everything is getting recorded. So here's the script:

First, you don't have "around" in your initial trigger. Second, you don't have anything set up to match either the shield or the held item.

Alright, so here's what recorded:

bull elephant leather helmet
ice ring

jeweled bracer
jeweled bracer
Amulet of Kwainin

MacAllen clan kilt
bull elephant leather boots
bull elephant leather gloves
bull elephant leather sleeves

knight doll

It seems that my neck2 isn't working. Also, though the right and left bracer is working, left and right ring seem to have problems. It doesnt see the shoulder wrap or the tunic, which suggests something with those if statements. I'll look into them after my homework, but maybe someone can find out what's wrong faster and teach me something. Very Happy

Trying to apply these concepts elsewhere to practice, doing it with my bed variable but I have an issue:

#$!@# !@#$^& #@! %^&*& #$^&. It is doing exactly what you have asked for. The initial space is being replaced by a pipe with every other space. That initial space is there because that is what your pattern says to capture into %1. I am not giving you the solution for this one, just telling you were to look.
