[Snippet] GetLatency (Ping)

[TriggerHappy]

Use the function to find out how long it takes for a player to communicate with the host (ping).

library GetLatency requires TimerUtils

    globals
        private gamecache Cache = InitGameCache(SCOPE_PREFIX)
    endglobals
    
    function GetLatency takes nothing returns integer
        local timer t = NewTimer()
        local real elapsed
        
        call TimerStart(t, 0.006, true, null)
        call FlushGameCache(Cache)
        call StoreInteger (Cache, "0", "0", GetPlayerId(GetLocalPlayer()))
        call TriggerSyncStart()
        call SyncStoredInteger(Cache, "0", "0")
        call TriggerSyncReady()
        call GetStoredInteger (Cache, "0", "0")
        call FlushStoredMission(Cache ,"0")
        
        set elapsed = TimerGetElapsed(t)
        call ReleaseTimer(t)
        
        return R2I(elapsed * 1000)
    endfunction
    
endlibrary

I really need someone to test this online, I'm not 100% sure it works.

Shouldn't it return the latency in milliseconds? Because currently it returns seconds, (a.k.a. 0 most of the time). Unless there's something I do no know about TimerGetElapsed, but in that case I'm sorry.

Yeah, you're right. I forgot to multiply when converting to integer.

why *100 and not *1000?

ApparentlyTriggerSyncReadydoesn't pause the thread.

Can anyone confirm this? I should be able to make a proper version of this once I get home.

EDIT There's no point for me to work on this if I can't test it, so lets just let this sit here for a few days until I can

If you have wc3 ready(installed), we can test it tomorrow if you want(I could only test it with kloader)

@TriggerHappy: TriggerSyncReady pauses the thread for me in:

It pauses the thread, but it doesn't wait until a synchronization is complete.

You can say that it does, but then you'd be wrong ^)^. Remember, I wrote Network ;P.

When does it fail to wait for the synchronization? Just curious, I haven't stress tested it. I just know it works consistently with a small number of synchronizations (at least on LAN, I haven't tested it on BNet).

edit: Nvm, explained in chat.
