Hi, I need help with the logic of this system.

I want my map to change every 4 hours, but always in a different order.

For example I have: map 1 / map 2 / map 3 / map 4

When the server starts, Start in map 3, then follow map 1, map 4 and map 2.

Whenever the server starts, it will be a different order.

And without restarting the server, if the cycle ends, change the map again, in a different order.

Suggestions for logic? It doesn't matter if we use mysql to have the values stored

Hello beenii,

You need a few tools to help you with that, in fact it's going to be using crontab and a little bash knowledge you can earn from reading stackoverflow pages.

Here you can find information about crontab: crontab(5): tables for driving cron - Linux man page (https://linux.die.net/man/5/crontab)

Here's a very hacky but very fast way to do this:
1. create 4 config.lua with different names, each of them containing the map you want to have. The order doesn't matter now.
2. set a cron job to stop your running server at specific times, you'll find more to it in the above link about crontab.
3. set a cron job to run a bash script that will rename the current config.lua to a name of your choice, and rename the "next config" to config.lua, that one you want to run. just mind timing it a few seconds between closing your server and restarting it :)
4. set a cron job to start your server again.

If you have further questions let me know, I maybe can help you with that.

Best Wishes,
Okke

I think I did not explain my problem well, An apology for that.

I will not change the map, I will change the players from townid, in total I will have 4 temples, where every certain hours they will be transported.


When the server starts, Players Start in town 3, then follow next houra teleport to town1, townid 4 and townid 2.

Whenever the server starts, it will be a different order.

And without restarting the server, if the cycle ends, change the townid again, in a different order.


This is normal system change town ID players online and offline

Lua: 
local config, new = {
    minTownId = 1,
    maxTownId = 3
}, 0
function onThink(interval, lastExecution)
    for _, pid in ipairs(getPlayersOnline()) do
        local town = getPlayerTown(pid)
        new = town < config.maxTownId and town + 1 or config.minTownId
        doPlayerSetTown(pid, new)
        doTeleportThing(pid, getTownTemplePosition(new))
        doRemoveConditions(pid)
        doCreatureAddHealth(pid, getCreatureMaxHealth(pid))
        doCreatureAddMana(pid, getCreatureMaxMana(pid))
            doBroadcastMessage("Map has been changed! Next map change will be in 25 minutes!", MESSAGE_STATUS_WARNING)
    end
    db.executeQuery("UPDATE players SET town_id = ".. new ..", posx = 0, posy = 0, posz = 0;")
    return true
end


I try to do the same, but that my 4 townids randomly without repeating themselves.

First townid 2 follow townid 4, next townid 1,next townid 3.

When finish cycle, have new order

hey, try this:


server lib:
Lua: 
MAPCHANGER_towns = {
    ['thais'] = {id = 1},
    ['venore'] = {id = 2},
    ['carlin'] = {id = 3},
    ['darashia'] = {id = 4}
}

MAPCHANGER_used_towns = {}

function table.contains(table, element)
    for _, value in pairs(table) do
        if value == element then
            return true
        end
    end
    return false
end

onThink:
Lua: 
function changeMap(id)
    for _, pid in ipairs(getPlayersOnline()) do
        doPlayerSetTown(pid, id)
        doTeleportThing(pid, getTownTemplePosition(id))
        doRemoveConditions(pid)
        doCreatureAddHealth(pid, getCreatureMaxHealth(pid))
        doCreatureAddMana(pid, getCreatureMaxMana(pid))
        doBroadcastMessage("Map has been changed! Next map change will be in 25 minutes!", MESSAGE_STATUS_WARNING)
    end
    db.executeQuery("UPDATE players SET town_id = ".. id ..", posx = 0, posy = 0, posz = 0;") 
end

function chooseMap()
    -- reset maps if all have been used
    if #MAPCHANGER_used_towns == #MAPCHANGER_towns then
        MAPCHANGER_used_towns = {}
    end
  
    -- choose new different map
    for town, info in pairs(MAPCHANGER_towns) do
        if not table.contains(MAPCHANGER_used_towns, town) then
            table.insert(MAPCHANGER_used_towns, town)
            changeMap(info.id)
            break
        end
    end
end

function onThink(interval, lastExecution)
    chooseMap()
    return true
end

let me know how it works i made while cooking xd

next map.png

analyze the script in detail.

1.- the same order is always repeated
2.- and when the cycle ends, it doesn't make any more townid changes, until I restart the server

Hopefully you can help me, I want to implement the current map and the next map on the website.
if you can register the town order in mysql, and when the loop ends, another order.

i need send data of mysql for show in website
mapweb.png

When I imagined this system, I did not think that the logic would be so complicated xD

thats my bad, you can use:
Lua: 
function shuffle(tbl)
  for i = #tbl, 2, -1 do
    local j = math.random(i)
    tbl[i], tbl[j] = tbl[j], tbl[i]
  end
  return tbl
end

and do like this:
Lua: 
local MAPCHANGER_towns = {
    ['thais'] = {id = 1},
    ['venore'] = {id = 2},
    ['carlin'] = {id = 3},
    ['darashia'] = {id = 4}
}

MAPCHANGER_towns = shuffle(MAPCHANGER_towns)

this way, you will always get different order

    end
    chooseMap()

end


you can use:
Lua: 
MAPCHANGER_neworder = {}
to see the next map and send to db

havent tested it but should do the job

I just ran several tests, if I improve, but still not working 100%

nextmap actu.png

the cycle repeats, but in the same order.

1.- only when i restart the server, or refresh the script changes the order.
2.- townid 1 never shows up
3.- when the cycle ends, in the next change the script does nothing, until it sends again a second time, the same cycle begins

I tried adding 2 extra town id, and the result was that now the loop was showing 2 townid

How get order from website with: MAPCHANGER_neworder = {} ?
- this is next map?
getTownId(MAPCHANGER_neworder)


I came up with a simpler function to solve this system:
we simply need a function that order numbers xD

for example put:
shuffle(1,2,3,4,5)
result:
shuffle.[1]=5
shuffle.[2]=2
shuffle.[3]=1
shuffle.[4]=3
shuffle.[5]=4

use again shuffle(1,2,3,4,5,6)
shuffle.[1]=2
shuffle.[2]=4
shuffle.[3]=6
shuffle.[4]=5
shuffle.[5]=1
shuffle.[6]=3

obtaining the numbers, everything else is the simplest, with some tables, the name of the town id is taken, and all the information.

I did not post the trick behind as i expect you to figure it out, but trust me its very easy to use the second version to be 100% as you want and also send the info to website.

anyway, as you asked here:
How get order from website with: MAPCHANGER_neworder = {} ?

solution:
the output of that table is the map order, which you can send by query to db. then use the php to read the db and list next map.

i like the fact you are playing with it, lua is funny and easy to learn.

Thanks for your help, I'll see how I solve that order :D

Eventually, you will get the same map twice in a row since there is no check for the current town id
