[Tutorial] - How to make the game check who is the host

Garbage.

Nevermind...

There already was one like this here.

I sure hope you didn't steal any of it.......

I didn't knew such tutorial existed, I don't even have an account on that website. I actually only think I have visited it 1 or 2 times ever and that is long ago. This tutorial was made by me with guidance from my friend Zoxc

It's spelled "Finished"

 

[ragingspeedhorn]

Oups, small error, well I will fix that

FYI, this isn't bug proof.
If the host is tabbed out from the game another player may have a faster response time and will be flagged as host by that function.

I suggest that you take the player that is flagged as host the most times out of 5 tests that are spread out a few seconds.

 

[ragingspeedhorn]

Really? I have never experienced such problem, please post your suggestion on how to "spreading it out" as you say because I am not exactly sure what you mean

 

[phyrex1an]

It is discussed in the thread that Evan posted, it also mentions the problem when the host leaves.

I suggest something like this:
1 variable
player udg_Host = null

function GetHostId takes nothing returns integer
    //This stores the Id + 1 for each player.
    call StoreInteger(GameCache(), "missionKey", "key", GetPlayerId(GetLocalPlayer()) + 1)
    //Setup the TriggerSyncReady call.
    call TriggerSyncStart()
    //Sync the value of the entry for each player.
    //Each value will sync to the value of the host.
    call SyncStoredInteger(GameCache(), "missionKey", "key")
    //Wait until the Game Cache syncs the key for everyone.
    call TriggerSyncReady()
    //Return the synced value as a id.
    return GetStoredInteger(GameCache(), "missionKey", "key") - 1
endfunction

function GetHostAverage takes nothing returns nothing
    local integer array id
    local integer max = 0
    local integer t = 0
    local integer i = 0
    set udg_Host = null
    loop
         exitwhen i > 11
         set id<i> = 0
         set i = i + 1
    endloop
    set i = 0
    loop
         exitwhen i &gt; 5         
         set t = GetHostId()
         set id[t] = id[t] + 1
         if id[t] &gt; id[max] then
                set max = t
         endif
         set i = i + 1
         call TriggerSleepAction(1)       
    endloop
    set udg_Host = Player(max)
endfunction</i>

Completely untested ^^
The function GetHostAverage should be called at map init and when the host leaves the game.
If udg_Host is null then the function hasn't found a host.

Note: The GameCache function is unimplemented here and is left as an exercise to the reader. I suggest that you use a game cache that you already use in your map instead of creating a completely new one. If your map is gamecache free then you have no other choice of course.

I am not that keen with jass but let me get this right, so when the host leaves the game run a similar check and it takes the second guy which joined the game?

 

[AceHart]

> and it takes the second guy which joined

Let's say, it takes someone else, not necessarily the second that joined.

 

[ragingspeedhorn]

Hmm, I don't know how handy the part with picking a new "leader" after the original host is gone is, the host usually leaves for a reason (unless he lags out or something like that).

Anyways as said I am not the best jasser (actually I stink) so to get this new way of doing it to work I need to replace your lines of coding with the ones that I had and then call "GetHostAverage" instead of "gethost()" in the Map Inilization trigger and replace the variable I have now with your suggestion?

Just to make sure I got it right ^^

 

[phyrex1an]

Yea that is correct.

Just as a reminder, GetHostAverage isn't instant. It takes a couple of seconds before you can use the udg_Host varaible.

 

[ragingspeedhorn]

Okay, so before I use it I should put in a wait of lets say 2-3 seconds?

If anything this is free trigger code... but seems more like your having a problem with it and this is a help thread.

Well I had no problem with the normal gethost() code, it worked fine for me and I didnt even knew that it could bug up untill I was told here, but since I am not the best at jass I just wanted to make sure I got everything right with the more efficient way the other guy gave. But yes this might be more of a free trigger code than tutorial so this should just be locked and trashed or something.

 

[phyrex1an]

Well, if you add a 'How do this work' to the post then it's a tutorial ^^.
The theory behind this code is pretty interesting, I didn't know how the Sync functions worked before I read this function.

BTW, there is no need to close a thread just becuse it isn't a tutorial.

 

[Grundy]

another thing you can do is add a trigger for a player message event

e: player 1-12 types -check host as an exact match
c:
a: set udg_Host = Player( GetHostId() )

incase the host is tabbed out and someone else gets flagged as the host, when the host comes back in he can type "-check host" and he will be flagged as the host


wait...why does this not work for me? when i try to put this function in my map it highlights this line
call StoreInteger( GameCache(), "missionKey", "key", (GetPlayerId(GetLocalPlayer())+1) )
and it says "Expected a name"

The JASS trigger isnt exact. U need to make ur own GameCache().
