GMCP documentation

SsalissSsaliss
edited September 2015 in Mechanic's Corner
The question was raised earlier on a clan, and the current GMCP doc is rather outdated, so I figured I'd take a stab at documenting it a bit. Please note that this is completely unofficial, and may contain inaccuracies, but if an error is found I'll gladly edit and update this guide. Further, this guide will only document the messages themselves, and not how to get GMCP working (since that is client dependent). I'll list the messages alphabetically (so Char.Afflictions.Add first, and Room.Wrongdir last) to make it a bit easier to find what you're looking for.

  • Char.Afflictions.Add
    • Contains the following values:
      • name: The short name of the affliction (i.e. "paralysis")
      • cure: The method of curing (i.e. "eat puritydust")
      • desc: A description of what the affliction does (i.e. "Paralysis will freeze the muscles in your body, making many actions impossible until it is cured.")
    • This one fires whenever you get an affliction. Note, however, that if you get hit by an unknown affliction, this does not fire, and it only fires on overhauled afflictions.
  • Char.Afflictions.List
    • Contains a list of afflictions. The values of each affliction mirrors the values above.
    • This one fires whenever you use DIAG or FIRSTAID or similar, and it only contains overhauled afflictions. It is also sent once on login.
  • Char.Afflictions.Remove
    • Contains a single value with the affliction removed.
    • This will fire whenever an affliction is removed. Note that this only fires if it is an overhauled affliction.
  • Char.Defences.Add
    • Contains the following values:
      • name: The short name of the defence (i.e. "waterwalk")
      • desc: A description of what the defence does (i.e. "Water walking allows you to travel across water without the need for swimming.")
    • This one fires whenever you put up a new defence. Note that this only fires on overhauled defences.
  • Char.Defences.List
    • Contains a list of defences. The values of each affliction mirrors the values above.
    • This one fires whenever you check DEF. Note that the only defences contained in the list are overhauled defences. It is also sent once on login.
  • Char.Defences.Remove
    • Contains a single value with the defence removed.
    • This one fires whenever a defence is removed from you. Note that it only fires on overhauled defences.
  • Char.Items.Add
    • Contains the following values:
      • location: Where the item is added. Most commonly "room" or "inv", but can also have other values (such as containers).
      • item: A dataset with the following values:
        • id: The numerical ID of the item (as seen on II etc)
        • name: The short appearance of the item (i.e. "a wafer of purity dust")
        • icon: What kind of item it is (I only noticed it while writing this, but among the values are "commodity", "fiend", "pet", "container" and "lamp". I'll see if I can get more item types)
        • attrib: The attributes of an item. This has never been explained fully, but these are the best guesses I've seen so far:
          • e: Edible
          • g: Groupable
          • t: Takeable (i.e. not fixed in the room)
          • m: Mobile
          • c: Container
    • This fires whenever an item is added to the room
  • Char.Items.List
    • Contains the following values:
      • location: Where the items are. Most commonly "room" or "inv", but can also have other values (such as containers).
      • items: A list of items. The structure and values mirror that of the item dataset mentioned above.
    • This one fires in various ways:
      • A list of items in the room is sent every time you LOOK or QL in a room. If you move around, this is done automatically, but it doesn't happen if you follow someone.
      • A list of items in your inventory is sent in response to you sending Char.Items.Inv to the server.
      • A list of items in a container is sent in response to you sending Char.Items.Contents <ID> to the server.
  • Char.Items.Remove
    • Contains the exact same values as Char.Items.Add.
    • This is sent whenever an item is removed. When transferring items from one place to another (getting, dropping, putting) first a Char.Items.Remove is sent, followed by a Char.Items.Add.
  • Char.Items.Update
    • Contains the exact same values as Char.Items.Add.
    • This is sent whenever an item is changed. Most often, this happens when groups are manipulated (splitting, combining, etc).
  • Char.Name
    • Contains the following values:
      • name: The name of your character.
      • fullname: Includes titles and family name.
    • This is sent on login. It is NOT sent when titles are changed.
  • Char.Skills.Groups
    • Contains a list of the following values:
      • name: The name of the skill (i.e. "Combat")
      • rank: The rank (i.e. "Expert")
    • This is sent in response to you sending Char.Skills.Get to the server.
  • Char.Skills.List
    • Contains the following values:
      • group: The skill in question (i.e. "aethercraft")
      • list: A list containing the skill names.
      • descs: A list containing the skill descriptions.
    • The list and descs are matched. Thus, the first entry in descs is a description of the first entry in list, and so on.
    • This is sent in response to you sending Char.Skills.Get with a "group" value (i.e. Char.Skills.Get { "group": "aethercraft"} )
  • Char.Skills.Info
    • Contains the following values:
      • group: The skill in question (i.e. "aethercraft")
      • skill: The individual ability (i.e. "targeting")
      • info: The AB entry. Newlines are sent as \n
    • This is sent in response to you sending Char.Skills.Info with a "group" and a "name" value (i.e. Char.Skills.Get { "group": "aethercraft", "name": "targeting" } )
  • Char.Status
    • Contains the following values:
      • fullname: Your full name, including titles and family name.
      • level: The name of your level (i.e. "Demigod")
      • xprank: Your numerical ranking, or "unranked" if you're not yet ranked. Contains an ending, i.e. "100th".
      • explorerrank: Your explorer ranking in text, i.e. "a Cosmic Wayfarer"
      • race: Your race. Demigod counts as a race. Uncertain how it deals with racehats.
      • age: Your age. If your age has been adjusted, this shows your adjusted age.
      • guild: Your guild and guild title (i.e. "Shadowdancers (within Mother Night's Entourage)")
      • city: Your org and org title (i.e. "Glomdoring (Shadow Warden)")
      • order: Presumably the same as above, but I'm not in an order. Contains "none" if you're not in an Order.
      • family: Your family name.
      • gold: How much gold you have on you, including containers.
      • bank: How much gold you have in banks.
      • unread_msgs: How many messages you have that are unread.
      • unread_news: How many news articles you have that are unread.

    Thank you for taking the time to documenting this. I'm sure it'll help many people (including myself) to make better use of GMCP.

    Is there a gmcp for when any person logs into Lusternia that can show you logins and logouts?

    Nope. Closest you can get is to use the player-list regularly.

    Only way you can check that via events, is if you use the webclient. There's a js thing to retrieve that kinda stuff... If you could do it in Mudlet, you could check with hidden people came around, so yeah...

    edit; last I checked, it fired on hidden people with java.. so I'm only assuming.

    Could you expand on that a bit? What "js thing" lets you retrieve it?
    image
  • SyrenniaSyrennia
    js = javascript. 

    I can't say more than 'thing' because I forget exactly what it's called. It was a hook type thing, that retrieved game data. Remember someone in Achaea mentioning it, as a means to see how many different people logged in each day, and for approx. how long per day, as some experiment. Same client, so I imagine the exact same would be possible in Lusternia.

  • AkyaevinAkyaevin
    There is a json api which gives a list of characters logged in. It does not report characters with gems, and may not report characters off prime (I can't remember).

    There is a separate, more hidden page which provides the info to the feed on the Lusternia.com page. I don't think it reports logging in or out any more.
  • SsalissSsaliss
    edited September 2015
    Yeah, I know about that API. It can be found at http://api.lusternia.com/characters.json and is more or less exactly what you get from the GMCP Comm.Players.List call (I think the API includes people in the intro, where GMCP does not; I can't recall any other differences off-hand).

    EDIT: Hmm. It seems there's some difference... Need to dig into this. Might be that the API only excludes people with gems. Interesting...

    EDIT EDIT: Yep, seems so. I got Avurekhos (in a manse) via the API, but don't get him through GMCP. Bug? Feature? Only @Ieptix might know...

    Just for reasons, does anyone know if any gmcp stuff fires when you "probe" mobs?

    Nope, no GMCP message like that.

    If I had more knowledge in how to use these, I'd make up a packaged module for Mudlet for basic things like picking up essence when it drops and you regain balance.

    If anyone wants to do this (I don't use Mudlet, so I can't help you much), my suggestion is to set a flag to true when you get the IRE.Misc.Achievement event and set it to false on the Char.Vitals event. Create a trigger to the Char.Item.Add event that adds the items added to a pickup list if that flag is set to true. If you've got stratagems, it's dead simple; just use SM INSERT FREE GET <item> to autopickup when you get balance back. This will pick up everything that drops when you kill something, including gold (although if there's already gold in the room, it doesn't pick any gold up).
    image
  • ShaddusShaddus , the Leper Messiah Outside your window.
    I usually make a trigger for stratagems to pick up gold/essence for my characters, but I can't always afford to use a few hundred lessons just to get Stratagems.

    1) Make a script with the event of gmcp.Char.Vitals.
    2) if gmcp.Char.Vitals.balance == '1' and gmcp.Char.Vitals.equilibrium == '1' and not grab_attempt then
          for i,v in pairs(gmcp.Char.Items.List) do
             if string.find(v.name, "essence") then
                grab_attempt = true
                send("get essence",false)
                tempTimer(1, [[grab_attempt = false]])
                return
             end
          end
       end

    Something like that, if I remember correctly. I may have missed something, but I'm doing it completely from memory as I don't have access to mudlet right now. I know the bashing script on the forums has essence grabbing, the one Rialorm (formerly Chade) manages.

    eh, good start, but not quite. gmcp.char.items.list can contain the items in the room as well. You do want to fire a gmcp.char.items.inv to the server using sendGMCP first, then do trigger on that to do your scanning. At least in my tests, it always had room info (gmcp.char.items.list.location being "room" ), because that's updated every move/look

    I think you're a bit confused on what the intention here is, he's not looking at his inventory, he's looking at the items in a room to see if there is essence to grab. You're right in how you need to check an inventory, because inv list isn't updated a lot. 

    Really, the gmcp event that you need to use are 'gmcp.Char.Item.Add' to grab stuff after you kill something

    oops. Yep, you are right, I thought he was looking into the inventory, not the room. Then you are, of course correct.

  • ShaddusShaddus , the Leper Messiah Outside your window.
    Actually, all I wanted to do was trigger off an essence dropping line to pick up essence if I regain bal/eq.

    Played with IRE.Target a bit.

    This is all from the Mudlet pov, for other clients, you'll have to handle the sending gmcp stuff yourself and what not.
    First, gotta add IRE.Target to what Lusternia kicks back to you.

    sendGMCP([[Core.Supports.Add ["IRE.Target 1"] ]])

    That activates the target dealie. You can see the information with mudlet using

    display(gmcp.IRE.Target)

    Now, for the important part, setting your target.


    sendGMCP([[IRE.Target.Set "MOBNUMBER" ]])

    That will populate gmcp.IRE.Target, giving you output such as

    {
      Info = {
        short_desc = "the corpse of a prim and proper butler",
        hpperc = "0",
        id = "194836"
      }
    }

    or

    {
      Info = {
        short_desc = "a prim and proper butler",
        hpperc = "100",
        id = "194836"
      }
    }

    Something to note is that to update the HP value of the target after attacking it, you need to send the target command again, else it'll just keep saying 100 after you target them. Now go forth, and track that mob HP.

    Edit: So, discovered an interesting thing. IRE.Target doesn't seem to update when you set the target again, but rather when there's a fresh update from some other gmcp module. However, if you don't retarget, it doesn't shoot you the updated hpperc.

    Agreed. Hence posting about it. Think I submitted a bug report about it, I'll check later to make sure.

    Edit: So, discovered an interesting thing. IRE.Target doesn't seem to update when you set the target again, but rather when there's a fresh update from some other gmcp module. However, if you don't retarget, it doesn't shoot you the updated hpperc.
    It updates properly when I set the target again without needing another module firing, but I don't use Mudlet. Doesn't seem to be broken on the Lusternia side (unless it's got something to do with MCCP or something; I think Mudlet has that on by default)

    Out of curiosity, is this with a mob wailing on you after smacking it?

    Nope. I basically went and found a mob and changed my pinger (which normally sends Core.Ping every second) to instead set a target. I got the target data every second, without any kind of output inbetween. Just a constant stream of IRE.Target.Info.

    Unless you meant that the HP value of it doesn't change until other things do. I never tested that, I guess.

    That, and I ran into the issue that if I changed targets, it didn't update until I changed rooms, vitals changed, etc.

    Do you know if you've got MCCP enabled in Mudlet? (I think it's called MCCP; the compression thing).

    Not sure. I'll have to check when I get home tonight.
