Lua Only one boss can be present

[Yalasari]

Hello,

I have boss spawning script using globalevents, boss appears every 12 hour + random addtional time, and there's problem, if nobody will kill boss, duplicate will appear, then next one appears, next one ...
And i have problem how to pause this script if already boss is present. (in script, demon is only for explain purposes)

local xrand = math.random(-2, 2)
local yrand = math.random(-2, 2)

local position = Position(930 + xrand, 1265 + yrand, 10)
local addtionalTime = math.random(0, 180) * 60 * 1000

local function spawnBoss()

    Game.createMonster("Demon", position)
   
    addtionalTime = math.random(0, 180) * 60 * 1000
   
    xrand = math.random(-2, 2)
    yrand = math.random(-2, 2)
   
    position = Position(930 + xrand, 1265 + yrand, 10)
   
    addEvent(spawnBoss, 12 * 60 * 60 * 1000 + addtionalTime)

end

function onTime(interval)

     addEvent(spawnBoss, addtionalTime)
     
     return true
     
end

Thanks in advance

Add a Global Storage at spawnboss function and make a check on ontime function

local xrand = math.random(-2, 2)
local yrand = math.random(-2, 2)

local position = Position(930 + xrand, 1265 + yrand, 10)
local addtionalTime = math.random(0, 180) * 60 * 1000

local function spawnBoss()

    Game.createMonster("Demon", position)
 
    addtionalTime = math.random(0, 180) * 60 * 1000
 
    xrand = math.random(-2, 2)
    yrand = math.random(-2, 2)
 
    position = Position(930 + xrand, 1265 + yrand, 10)
 
    addEvent(spawnBoss, 12 * 60 * 60 * 1000 + addtionalTime)
    -- Add Global storage
end

function onTime(interval)
 -- if Global Storage == 1
     addEvent(spawnBoss, addtionalTime)
--end
     return true
   
end

Create a creatureevent Script that sets Storage to 0 if Boss is killed (onDeath or onKill depends on tfs version)

What TFS version?
Do you have this code? forgottenserver/game.lua at master · otland/forgottenserver · GitHub

Game.setStorageVaule(66001, 1)

Ow man, i am so dumby... thanks <3

 

[Infernum]

you'd still need a way to reset the storage value
you can do it by registering a death creatureevent to the boss to reset the global storage value

 

[Yalasari]

I already done it in separate onDeath() function called by creatureevent.xml

So you did what I suggested you, good job.
