PingMe function (using the idea of GetHost)

I've been wondering how the guy did this. If you only run the sync functions for 1 player wouldnt that cause a desync?

Also, how does he meassure the time? A timer?

Vexorian	My guess is that he measures the time for LocalPlayer and then Syncs the time measured

iNfraNe	But im wondering how he meassures the time for localplayer. I dont really need to sync the time afterwards since im just gonna display it ingame (which shouldnt desync right?)

PitzerMike	He may just have started a timer at 0.00 game time and then GetTimerElapsed(). He may also have used the jAPI GetTicks native with a loader.

So then, this should be correct?

JASS:

function PingPlayer takes player p returns real
  local timer t = CreateTimer()
  local real r
  call StoreInteger(GC(), "a", "a", 1)
  call TimerStart(t, 10., false, function CleanPingTimer)
  if GetLocalPlayer() == p then
    call TriggerSyncStart()
    call SyncStoredInteger(GC(), "a", "a")
    call TriggerSyncReady()
  endif
  set r = TimerGetElapsed(t)
  set t = null
  return r
endfunction

And it should return 0.00 for all other players than the one being pinged.

If this is correct so far then I'd like to know how to make player2 aware of player1's delay, how could I sync the real value?

Edit: this function desyncs, which I thought it would :( any ideas?

PipeDream	the only way known to reliably transmit information is via SyncSelections Transform the real into 12 bit fixed precision and then search around for Mike's optimized Sync12BitInteger.

iNfraNe	I tried that... JASS: set udg_Latency[i] = Sync12BitInteger(Player(i), R2I(PingPlayer(Player(i)) * 1000)) But it still desyncs... Any idea how to fix?

DioD	Delay returns to wrong local player.

iNfraNe	Erm, as always, I dont see your point. Be more clear please.

DioD	if GetLocalPlayer() == p then call TriggerSyncStart() call SyncStoredInteger(GC(), "a", "a") call TriggerSyncReady() Sync with others localy....

Well yes, it would seem desyncy, but tennis claims its possible:
