Close door, party system, skill lock

tekproxy · Post by **tekproxy** » Wed Apr 19, 2006 6:00 am

If I coded the hook to handle the close door macro, a package to handle party systems and a package to handle the skill locks, could I then send you the code OR are you already working on these and they're laying around half finished not in the distro yet?

These are just some things I saw unfinished and I think I could do. I'll be sure to code them with propper documentatioin, spacing and naming and all that.

Madman isn't answering his e-mail so I've got to bother you MuadDib.

Sorry to interfere.

I have some fully implemented party system script lying around here... would need to be adjusted to the packet hooks though.
(if anyone knows how to use the packethook this is won't take long I guess).

It's about 3 years old, since then i haven't scripted much for POL.

I could paste it here, if anyone's interested.

Was it written by Kinetix? I found some of his old code on Folko's forums about a party system. If it works well post it and I'll try to get it working. If you don't know who wrote it or someone removed the Authors name, I'll compare the two and we'll find out.

Does anyone know anything about the Chat system?

No it's completely written by me... but I remember someone doing it again...and I think folko wrote one at the same time I did.

(Max at Folkos forum = me.. you'll find a thread somewhere there.)

Chat system... yup, i also have a script for that (but it's limited to one global chatroom)

EDIT:

Ahh i found kinetix's script on folko's forum. Never tried it though.
Well I didn't know this was around... makes my offer kindof obsolete:-)
I suppose it works or he wouldn't have released it.

Oooh, ok. I just read that thread, in fact. Cool!

So the party system would have to be rewritten for packet hooks? From what I can tell that wouldn't be that hard to do. If you want and you're feeling generous, post your code or e-mail it to me and I'll go over it and try to get it working and posted back up here. If you don't feel like it then don't worry I'll mess around with this other code and packet list, but I may bother you from time to time now that I know you already know how it's done.

How difficult would it be to expand the chat system to be OSI-like? I don't even know how OSI handles their chat system. I've barely messed with it.

Well I can send you all the party system stuff I have and together with kinetix's you should have enough infosrmation if you encounter any problems.

I was quite bitchy back then about giving away my private shard code...
but by now I don't really care as I'm not active anymore.

Converting to the hooks is not really hard I think... I don't really know how they work so it stays an asumption;-)

OSI-Chatsystem: No idea how that works but I think there's more than one room/channel to talk in.

Actually I guess I was just too lazy to extend it t... but I might have missed packetinfos as well, I really don't remember.

EDIT: I need your email address;-)

This is PartySystem.src

Code: Select all

use uo;

include "include/PartySystem";

program PartySystem(ch, data)
  var dataarray := SplitWords(data);
  if (dataarray[1] = "ClientPacketbfSubcommand6")
    if (dataarray[2] = "Subsubcommand1")
      var pmserial := CInt(dataarray[3]);
      AddPartyMember(ch, pmserial);

    elseif (dataarray[2] = "Subsubcommand2")
      var pmserial := CInt(dataarray[3]);
      RemovePartyMember(ch, pmserial);

    elseif (dataarray[2] = "Subsubcommand3")
      var pmserial := CInt(dataarray[3]);
      var startind := len(dataarray[1]) + len(dataarray[2]) + len(dataarray[3]) + 4;
      SendMessageToPartyMember(ch, pmserial, data[startind, len(data)]);

    elseif (dataarray[2] = "Subsubcommand4")
      var startind := len(dataarray[1]) + len(dataarray[2]) + 3;
      SendMessageToParty(ch, data[startind, len(data)]);

    elseif (dataarray[2] = "Subsubcommand6")
      var pcanloot := CInt(dataarray[3]);
      if (GetObjProperty(ch, "parray"))
        SetObjProperty(ch, "pcanloot", pcanloot);
        if (pcanloot = 0)
          SendSysMessage(ch, "Your party cannot loot your corpse.");

        elseif (pcanloot = 1)
          SendSysMessage(ch, "Your party can loot your corpse.");
        endif
      endif

    elseif (dataarray[2] = "Subsubcommand8")
      var plserial := CInt(dataarray[3]);
      SetObjProperty(ch, "pinvitation", {plserial, "accepted"});

    elseif (dataarray[2] = "Subsubcommand9")
      var plserial := CInt(dataarray[3]);
      SetObjProperty(ch, "pinvitation", {plserial, "declined"});
    endif
  endif

That's the whole interface to the party system. It's a textcmd.. I guess you know how that stuff was supposed to work;-)

I'm no heathen! I'll make sure you're noted.

It will take me a while to pour over this code. Thank you very much for your help. If muad doesn't want this, at least I do.

Oh, do you know why no one ever uses the in-game gumps for the party system?

Max Scherr · Post by **Max Scherr** » Wed Apr 19, 2006 10:29 am

What exactly do you mean with in-game gumps?

Those packets handled by my (and i also think kinetix's) script are also sent from those party system gumps (opened by this scroll in the pd next to the charprofile)

The client sends the same if you are using the partysystem gump or commands like /add /remove and so on.

But you might have meant something else...

If you need any additional packet infos I can check the source of my client-proxy app I used for capturing the client info... I was too lazy to learn c back then so I couldn't use folko's hook ...

EDIT:

Oh well I just copy & pasted the packet editing functions:

Code: Select all

function manipulpacketBF(packetstr: String): String;
var
  subcommand: Word;
  subsubcommand: Byte;

begin
  Move(packetstr[4], subcommand, SizeOf(Word));

  if subcommand = 6 then
    begin
      Move(packetstr[6], subsubcommand, SizeOf(Word));
      case subsubcommand of
        1: Result := manipulpacketBFsc6ssc1(packetstr);

        9: Result := manipulpacketBFsc6ssc9(packetstr);
        3: Result := manipulpacketBFsc6ssc3(packetstr);
        4: Result := manipulpacketBFsc6ssc4(packetstr);
        6: Result := manipulpacketBFsc6ssc6(packetstr);
        2: Result := manipulpacketBFsc6ssc2(packetstr);

      end;

    end

  else if subcommand = $15 then
    Result := manipulpacketBFsc15(packetstr)

  else if subcommand = $13 then
    Result := manipulpacketBFsc13(packetstr)

  else
    Result := packetstr;

And for the chat:

Code: Select all

function manipulpacketB5(packetstr: String): String;
var

  Result := newpacketstr;

end;

function manipulpacketB3(packetstr: String): String;
var
  hexstr, newpacketstr: String;

begin
  hexstr := GenHexStr(Addr(packetstr[2]), Length(packetstr) - 1);
  newpacketstr := createspeechpacketstr('.Chat ClientPacketb3 '+ hexstr);
  Form1.ListBox1.Items.Add('Manipulated packet $B3!');
  Result := newpacketstr;

end;

Thanks for posting this stuff. I worked on the party system all day and I got add, remove, accept and decline working. Most of the files are organized and I think I have 95% of the kinks worked out (on the code that works). I'm limited on how the party system is SUPOSED to work, so I'll need someone to correct any of my mistakes.

I should have the party system done in a few days. I use definitions present in the BFCommand package in the 096 distro, though. Hopefully this will make Muad's job of adding my scripts in easier...

...will ja nix sagen, aber noch umstÃ¤ndlicher kann man die Packet-Zusammenbastelei net machen (vor allem, die Geschichte Buchstabe -> Hex)?

(bitte net zu negativ auffassen ;o)

Shinigami

Max Scherr · Post by **Max Scherr** » Thu Apr 20, 2006 1:07 am

Nichts fuer ungut, aber negatives kann man ja nur negativ auffassen

Is nicht so tragisch;-)

Kritik ist ja immer gut, wobei sie hier halt fuer die lernenden Besucher des Forums wichtiger waere als fuer mich.

Das Zeug ist naemlich von 2002 oder so und da hatte ich wirklich kaum Ahnung von irgendwas :?

Es soll ja nicht als Top-Referenz dienen, sondern helfen falls es irgendwo Unklarheiten gibt, wann was zu senden ist etc.

Wegen den Umwandlungen... in sogut wie jeder Sprache gibts ja ne Umwandlung von Buchstabe zu Zahl... aber die hab ich damals wohl nicht gefunden in escript

oder andere Theorie: "ich war zu faul" oder ich wusste das damals noch gar nicht... naja lange her, alles vergessen. Erstaunlich dass ich die Scripts ueberhaupt noch hab.

EDIT:

Gefunden

LOL

CAsc( str );
CChr( number );

Naja, wenn auch der Code etwas schlampig ist, immerhin hab ich die ganzen Sachen mit pol92 zum laufen gebracht. Das ist dann aber auch das einzige worauf ich stolz bin

To everyone who doesn't speak german: There's absolutely nothing important in this post

I should have paid more attention in german class.

(Is that correct? I would visit the pol forums more often if I got free german lessons...)

Max Scherr · Post by **Max Scherr** » Thu Apr 20, 2006 11:48 am

"du auch" should be "dich auch" but besides that it's correct, although you might confuse people a bit with that

We were just talking about how stupidly I did all the packet "packing" especially the Hex <-> Character conversion. :?

tekproxy · Post by **tekproxy** » Thu Apr 20, 2006 1:12 pm

Thank you. I didn't pay very good attention when the teacher went over that part.

Yes that code was a little scary. It has helped point me in the right direction though but I'm not using any of it. I might use some of the chat code or use it for more inspiration. I really appreciate it.

Since this is my first time coding packet hooks I had to learn a few things but I've been coding almost non-stop on this since I've started, so I'm no slacker.

Add, remove, accept and decline work, but I need to clean it up a bit and add in more comments. I was using strings to set the packet information, which I think is a little ugly and Racalc's guide uses Set functions, which I think look better and make more sense.

I also got party stats to update correctly so you can view the health, mana and stamina of your party. That was a little tricky for me... Chat and Message functions are almost done and I should have those finished by the end of the day.

What is the standard color for OSI party messages? I keep getting the feeling it was a nice green, or perhaps no color at all. I'll go with green if no one knows.

Max Scherr · Post by **Max Scherr** » Thu Apr 20, 2006 1:32 pm

Yup...I remember green but me playing on OSI ... that was 2000 I think (age 15)...

tekproxy · Post by **tekproxy** » Thu Apr 20, 2006 6:11 pm

Ok I finished, for the most part. Now it's time to hammer out any possible kinks I may have overlooked and optimize the source as best I can.

I have most settings stored in an include file where someone could set the constants however they wanted. The default font color is green

It brings back memories.

Should I make liberal use of set_critical() with the packet handling logic? It works if I don't and I haven't had any problems without it.

tekproxy · Post by **tekproxy** » Fri Apr 21, 2006 3:31 pm

I've been playing with the party system all day now and it's working fairly well. There may be bugs in it, but I've tried to eliminate all of them. Here's the forum topic:
http://forums.polserver.com/viewtopic.php?t=289

I found out while playing with this that the client sends packets when you manually type in party commands in addition to when you use the party scroll. That's neat, I thought I was going to have to do that.

tekproxy · Post by **tekproxy** » Sat Apr 22, 2006 4:39 am

I'm working on a skill lock system that uses packet hooks. The hook part is finished (and was easy). The hard part will be editing attributes.inc. The logic for skill/locks goes something like this:

Code: Select all

if at skill cap
  if skill not set locked
    foreach other_skill for player
      if other_skill set to lower
        allow skill to advance
        lower other_skill by same amount
      endif
    endforeach
  endif
else
  // not at skill cap
  if skill set to locked or set to lower
    no gain
  endif
endif

Or maybe my logic is flawed. Luckily, UO.com says this about skill/locks:

Raise - When a skill is set to Raise (up arrow), this skill will increase as it is used..
Lower - When a skill is set to Lower (down arror), this skill will decrease if you're at the skill cap and gain in other skills. Skills set to Lower will not allow you to gain stats from use of that skill.
Lock - When a skill is set to Lock (padlock), this skill's value will not change. Skills set to Lock will not allow you to gain stats from use of that skill.

I'm just trying to come up with an elegant way to add this to attributes.inc. I think I'm going to go with the one for the 096 distro since that's the one I use. If you're not using the 096 distro you'll just have to add in the checks yourself.

Post by **Tomi** » Sat Apr 22, 2006 7:11 am

I added my skill lock checks directly in awardpoints function, I think that's the easiest way to get it working well.

tekproxy · Post by **tekproxy** » Sat Apr 22, 2006 10:52 am

I realized making a version that can easily work with both the 095 and 096 distro would be too difficult, so I made this for 096. Hopefully the devs like it enough to use it. I've tested this on my server and everything worked fine. Here's the link to my post:
