NPC [TFS 1.0] Marriage System

[Godely]

Almost 5 years since I released the Marriage System for TFS ~0.2-0.3, I took a day to remake it so that works with TFS 1.0. I still use live queries in the code since I didn't want to change any source code (and also to make it works with offline players).

Please, understand that TFS 1.0 is constantly changing and you should have the latest sources compiled to make it work (since some changes were made in events). Hope you like it!

Create a new NPC Priest.xml:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Priest" script="priest.lua" walkinterval="2000" floorchange="0">
    <health now="100" max="100"/>
    <look type="132" head="20" body="39" legs="45" feet="7" addons="0"/>
</npc>

And the corresponding lua file priest.lua:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid)            npcHandler:onCreatureAppear(cid)            end
function onCreatureDisappear(cid)        npcHandler:onCreatureDisappear(cid)            end
function onCreatureSay(cid, type, msg)    npcHandler:onCreatureSay(cid, type, msg)    end
function onThink()                        npcHandler:onThink()                        end

Now, on events/events.xml, enable the method onLook if it's not enabled. The line should be like this:

<event class="Player" method="onLook" enabled="1"/>

Continue on the next post...

 

[Godely]

Now, on events/scripts/player.lua, add the following piece of code after the local description variable is initialized in the method Player: onLook.

    if LOOK_MARRIAGE_DESCR and thing:isCreature() then
        if thing:isPlayer() then
            description = description .. self:getMarriageDescription(thing)
        end
    end

Now go on global.lua and add the following code:

PROPOSED_STATUS = 1
MARRIED_STATUS = 2
LOOK_MARRIAGE_DESCR = TRUE
ITEM_WEDDING_RING = 2121
ITEM_ENGRAVED_WEDDING_RING = 10502

function getPlayerSpouse(id)
    local resultQuery = db.storeQuery("SELECT `marriage_spouse` FROM `players` WHERE `id` = " .. db.escapeString(id))
    if resultQuery ~= false then
        local ret = result.getDataInt(resultQuery, "marriage_spouse")
        result.free(resultQuery)
        return ret
    end
    return -1
end

function setPlayerSpouse(id, val)
    db.query("UPDATE `players` SET `marriage_spouse` = " .. val .. " WHERE `id` = " .. id)
end

function getPlayerMarriageStatus(id)
    local resultQuery = db.storeQuery("SELECT `marriage_status` FROM `players` WHERE `id` = " .. db.escapeString(id))
    if resultQuery ~= false then
        local ret = result.getDataInt(resultQuery, "marriage_status")
        result.free(resultQuery)
        return ret
    end
    return -1
end

function setPlayerMarriageStatus(id, val)
    db.query("UPDATE `players` SET `marriage_status` = " .. val .. " WHERE `id` = " .. id)
end

function Player:getMarriageDescription(thing)
    local descr = ""
    if getPlayerMarriageStatus(thing:getGuid()) == MARRIED_STATUS then
        playerSpouse = getPlayerSpouse(thing:getGuid())
        if self == thing then
            descr = descr .. " You are "
        elseif thing:getSex() == PLAYERSEX_FEMALE then
            descr = descr .. " She is "
        else
            descr = descr .. " He is "
        end
        descr = descr .. "married to " .. getPlayerNameById(playerSpouse) .. '.'
    end
    return descr
end

LOOK_MESSAGE_DESCR should be set to FALSE in case you don't want the marriage info to appear in the look description of a player (e.g. You see Godely. He is married to Lalala.).

Now, go to compat.lua and add those following functions somewhere in the code:

function getPlayerNameById(id)
    local resultName = db.storeQuery("SELECT `name` FROM `players` WHERE `id` = " .. db.escapeString(id))
    if resultName ~= false then
        local name = result.getDataString(resultName, "name")
        result.free(resultName)
        return name
    end
    return 0
end

Now, the last thing to do is execute the following command on the database:

ALTER TABLE `players` ADD `marriage_status` tinyint(1) NOT NULL DEFAULT 0, ADD `marriage_spouse` int(11) NOT NULL DEFAULT -1

Another option is to paste the following code on 18.lua, in migrations, run the server and undo it:

function onUpdateDatabase()
    print("> Updating database to version 19 (add marriage info to players table - marriage_status determines if the player is married and marriage_spouse determines to whom)")

    db.query("ALTER TABLE `players` ADD `marriage_status` tinyint(1) NOT NULL DEFAULT 0, ADD `marriage_spouse` int(11) NOT NULL DEFAULT -1")
    return false
end

That's it, the marriage system should be working on your server. To marry someone, a person with NAME1 would just say hi, marry, yes, NAME2. Then, a person with the NAME2 would say hi, marry, yes, NAME1. The other commands are divorce, to divorce a player, of course, and remove, to remove a wedding proposal you made to someone. The code is not so big, so please take a time to look into it and contribute

 

[Zszywek]

Good work! I wanted to write it in future, but you done it first. Great job!

 

[Tazer]

Awesome, only the rings are missing and at those it should say who you married to aswell.. Good work

 

[dominique120]

 npcHandler:say('Since both youngs souls are willing to marry, I now pronounce you, {' .. player:getName() .. '}, and {' .. getPlayerNameById(candidate) .. '} married.', cid)

to

 npcHandler:say('Since both young souls are willing to marry, I now pronounce you, {' .. player:getName() .. '}, and {' .. getPlayerNameById(candidate) .. '} married.', cid)

Tiny typo, you wrote 'youngs instead of 'young'

I just tested it and it works perfectly. Too bad there are no rings though

 

[Godely]

Fixed the bugs reported and added the ring feature.

TODO:
- Don't allow a player to get married if he has not enough space to fit the rings.
- Only allow a wedding if the counterpart is online (otherwise both rings will have to go to the current player talking to the NPC, as it's happening now)
- Think about how to handle divorce regarding the rings. It's currently not breaking since the rings can be anywhere, not necessarily with the players.

 

[Jabra]

Awesome work. Should add outfits when marrige is accepted if they have Wedding Box when they leave the rings.

 

[putamerda]

Now, on events/scripts/player.lua, add the following piece of code after the local description variable is initialized in the method Player: onLook.

    if LOOK_MARRIAGE_DESCR and thing:isCreature() then
        if thing:isPlayer() then
            description = description .. self:getMarriageDescription(thing)
        end
    end

My events/scripts/player.lua dont have the local variable description look my player.lua

function Player:onLook(thing, position, distance)
    return true
end

function Player:onLookInTrade(partner, item, distance)
    return true
end

function Player:onLookInShop(itemType, count)
    return true
end

 

[Godely]

You have to update your TFS 1.0 as this has been already filled with code.

 

[Benna]

Worked like a charm, don't forgot to add the Priest npc in spawn-world.xml

 

[Eldin]

Will use this for sure, thank you.

Kind Regards,
Eldin.

 

[Nobrusz]

Good job, man. I really aprecciated it!

 

[otuserbyme]

which line do I add the events/scripts/player.lua

Help Me if must i instal uniServer but now i use xampp.

 

[Enzo.7]

I think i made something wrong, the npc is working the system is working, but when someone tries to accept the proposal it says that i've already made one to a player called "ZERO" (0)

The error is somewhere else in the script, post more.

 

[Thorn]

The error is somewhere else in the script, post more.

are you sure? because this marriage part is the line that is wrong according to the console, i'll post the whole thing just in case
