RevScripts BOOS Check - monster check - TFS 1.5 DOWNGRADE NEKIRO 8.0

[Bee King]

In my server, there are 4 open-world bosses, and I set their spawn time to be longer in the spawn XML… They are far from the city, so to check if they are there, you need to take a long walk.


Here comes my request...


I would like a script, an action ID to add to an item or maybe a sign… where, upon use, it shows whether the monster is on the map or not.


Example:


BOSS Demodras - Live
BOSS Dracola - Live
BOSS Flyfly - No live
BOSS The Old Widow - No live


I tried doing something with ChatGPT, but it couldn't find a function to check if a certain monster is on the map...


If anyone can help with this script, or maybe point me in the right direction, I would be very grateful...

Have you tried with this?

Thread '[1.X] Boss system (with checker, auto-respawn and day configuration)'

Aug 7, 2022

Hi! This system it's the outcome of a request thread Lua - [1.X] Boss checker (https://otland.net/threads/1-x-boss-checker.281905/#post-2701825), it has been made by @Xikini and it's been correctly tested on TFS 1.5 downgrades.

It has some samples for daily bosses (in this case Orshabaal, Ferumbras, Ghazbaran), and added Pits of Inferno bosses, just change the coordinates and everything will work. If you set the day to Any it will show the current day as spawn day.


To install, go to data/scripts and create a new file with:

local raidBossInformation = {
    {...

I've implemented it without any problem and works great, exactly as you want.

If you don't want to make any engine changes then you can attach script to a monster with onDeath / onSpawn event and handle GlobalStorageValues storing info if boss is alive - but it's worse solution when you want to increase boss number.

I don't think it's the same as what I want... I don't want data, hours, or anything like that. My bosses are regular monsters added with the map editor... like a rotworm, cyclops, etc.


As for the solution you suggested with globalstorages.
That's what I wanted, an event with onDeath on the monster, and a script to check if it's alive or dead using storages, but I couldn't make it.


I just wanted to know if they are alive on the map or not.

I think what I would do is make a revscript using onSpawn to flip a table value to true, while also registering an onDeath event to handle changing the table value to false when the boss dies. You should be able to reference that table in any other LUA functions, or just create a talk action like !bosslist. Something like this should work, although I seem to be making some mistake with onSpawn here:

ACTIVE_BOSS_LIST = {
    {name = "Demodras", live = false},
    {name = "Dracola", live = false},
    {name = "Flyfly", live = false},
    {name = "The Old Widow", live = false},
}

local spawnCallback = EventCallback
function spawnCallback.onSpawn(creature, position, startup, artificial)
    for i = 1, #ACTIVE_BOSS_LIST do
        if ACTIVE_BOSS_LIST[i].name == creature:getName() then
            creature:registerEvent("onDeath_registerBoss")
            ACTIVE_BOSS_LIST[i].live = true
        end
    end
    return true
end
spawnCallback:register()

local deathEvent = CreatureEvent("onDeath_registerBoss")
function deathEvent.onKill(creature, target)
    print(target:getName())
    for i = 1, #ACTIVE_BOSS_LIST do
        if ACTIVE_BOSS_LIST[i].name == target:getName() then
            ACTIVE_BOSS_LIST[i].live = false
        end
    end
    return true
end
deathEvent:type("kill")
deathEvent:register()

local talkaction = TalkAction("!bosslist")
function talkaction.onSay(player, words, param, type)
    local msg = ""
    for i = 1, #ACTIVE_BOSS_LIST do
        msg = msg .. "Boss " .. ACTIVE_BOSS_LIST[i].name .. ": " .. (ACTIVE_BOSS_LIST[i].live == true and "Live" or "Not Live") .. "\n"
    end
    player:sendTextMessage(MESSAGE_EVENT_ADVANCE, msg)
    return false
end
talkaction:register()

I tested this script, the command "works," but it always says the bosses are dead, even though they are there, alive and well. :|

Thread '[1.X] Boss system (with checker, auto-respawn and day configuration)'

Aug 7, 2022

Hi! This system it's the outcome of a request thread Lua - [1.X] Boss checker (https://otland.net/threads/1-x-boss-checker.281905/#post-2701825), it has been made by @Xikini and it's been correctly tested on TFS 1.5 downgrades.

It has some samples for daily bosses (in this case Orshabaal, Ferumbras, Ghazbaran), and added Pits of Inferno bosses, just change the coordinates and everything will work. If you set the day to Any it will show the current day as spawn day.


To install, go to data/scripts and create a new file with:

local raidBossInformation = {
    {...

The friend up there sent me this trend, but what I want is something much simpler... like what Boiga tried to do over there...

I'm not sure what mistake I'm making with onSpawn, maybe someone can point out the error

Post automatically merged: Mar 22, 2025

I got some help and the problem is that onSpawn is disabled by default. We can enable it by going to events/events.xml and changing onSpawn under "Monster methods" from 0 to 1.

I had a couple other mistakes in the previous code (onKill should be registered to the players, not the boss monster). Here is a working version:

local ACTIVE_BOSS_LIST = {
    {name = "Demodras", live = false},
    {name = "Dracola", live = false},
    {name = "Flyfly", live = false},
    {name = "The Old Widow", live = false},
}

local loginevent = CreatureEvent("login_registration")
function loginevent.onLogin(player)
    player:registerEvent("onKill_BossList")
    return true
end
loginevent:register()

local spawnCallback = EventCallback
function spawnCallback.onSpawn(creature, position, startup, artificial)
    for i = 1, #ACTIVE_BOSS_LIST do
        if ACTIVE_BOSS_LIST[i].name == creature:getName() then
            ACTIVE_BOSS_LIST[i].live = true
        end
    end
    return true
end
spawnCallback:register()

local deathEvent = CreatureEvent("onKill_BossList")
function deathEvent.onKill(creature, target)
    for i = 1, #ACTIVE_BOSS_LIST do
        if ACTIVE_BOSS_LIST[i].name == target:getName() then
            ACTIVE_BOSS_LIST[i].live = false
        end
    end
    return true
end
deathEvent:type("kill")
deathEvent:register()

local talkaction = TalkAction("!bosslist")
function talkaction.onSay(player, words, param, type)
    local msg = ""
    for i = 1, #ACTIVE_BOSS_LIST do
        if msg ~= "" then msg = msg .. "\n" end
        msg = msg .. "Boss " .. ACTIVE_BOSS_LIST[i].name .. ": " .. (ACTIVE_BOSS_LIST[i].live == true and "Live" or "Not Live")
    end
    player:sendTextMessage(MESSAGE_EVENT_ADVANCE, msg)
    return false
end

I made this change in events and also added the new script... it still says that all the bosses are dead

 

[Mateus Robeerto]

It's a pretty simple script. Here’s what you wanted—using the !bosses command to check the status of a boss, whether it's alive or dead. It doesn't matter if it's far or close; it verifies normally and works fine.


Note: If your source doesn’t have the getMonsters function, you’ll need to add it so that the script can check if the monster/boss is present on the map or not. This is very important.

Strange, it is working fine for me. Still, Mateus's solution is better, I didn't know that getMonsters() is an option. His code is simpler and faster so I would go with his if you can.

I'm sorry, what?
Let's say you have 1000 monsters scattered around on your server, with 20 bosses.
And let's say on average, when you search through the monsters it finds it after half the total monsters..

Every time someone uses this talkaction.. you're iterating through 500 * 20 -> 10,000 monsters to find out if the bosses are alive or dead.

That's just ludicrously inefficient.

Here is a working version:

Most likely you are typing the creatures names into the table without capitals.

You must write "Rat" instead of "rat" or "Dragon Lord" instead of "dragon lord"

 

[Mateus Robeerto]

Isso é ridiculamente ineficiente.

But he only has one boss each, not multiple bosses. If he has two Demodras or more, then it's fine—your script is much better. xD

Most likely you are typing the creatures names into the table without capitals.

You must write "Rat" instead of "rat" or "Dragon Lord" instead of "dragon lord"

Haha, I’m surprised you don’t like me anymore. I took the script you edited and tested it. There was a bug... I used the command to check if the boss was alive or not, and it worked fine. But then, I summoned Demodras and used the command—it showed as alive, which is correct. After killing Demodras, I used the command again, but it still said it was alive...


Note: Demodras is no longer on the map. Can you take a look and improve the script? xD

I don't hate people. I just dislike poorly made scripts.

You guys are probably using some old Lua version.. so we need to order the functions differently, so that the onLogin method registers after the onKill method is loaded.

Alright, updated and added some basic stuff.

Main drawback of this script is that you can only have 1 unique of each boss on the server.
If you want 2+ demodras for example, you need to change the script almost completely to accommodate that.

Added some basic prints as well, so you can debug in the console.

local ACTIVE_BOSS_LIST = ACTIVE_BOSS_LIST or {
    ["dEModRAs"] = {alive = false}, -- can name the boss however you want. won't affect the script.
    ["Dracola"] = {alive = false},
    ["Flyfly"] = {alive = false},
    ["The Old Widow"] = {alive = false},
}

local lowercased_boss_list = {}
for bossName, data in pairs(ACTIVE_BOSS_LIST) do
    lowercased_boss_list[string.lower(bossName)] = data
end
ACTIVE_BOSS_LIST = lowercased_boss_list
lowercased_boss_list = nil

local sortedBossNames = {}
for name in pairs(ACTIVE_BOSS_LIST) do
    table.insert(sortedBossNames, name)
end
table.sort(sortedBossNames)

local function titleCase(str)
    local result = str:gsub("(%a)([%w_']*)", function(first, rest)
        return first:upper() .. rest:lower()
    end)
    return result
end

It has nothing to do with old Lua...

I'm using a more recent TFS. I've tested several different bases, like TFS 1.4.2, 1.5, 1.6, etc., and there was still a bug, even after your last edit. I tested it again, and it didn’t work... I killed the boss, but it still appeared as alive.


I took your script and made some adjustments.


Now, when logging in, it shows information about the number of bosses. If you use the !bosslist command, it displays how many bosses exist. For example, if there are two Dracolas alive, the message will be: 'Boss Dracola alive: 2'. If you kill one and leave the other alive, it will show 'Boss Dracola alive: 1'. If you kill both, it will say they are dead.


I also added the spawn time functionality in the RME Editor. Now, it notifies everyone when a boss spawns and, when it's defeated, it announces it to everyone as well. Pretty simple and functional, without using the getMonsters function.
