Loops? - wups - 14.09.2010

I was just thinking, would a value checking be faster than
pawn Code:
IsPlayerConnected(playerid)
like
pawn Code:
public OnPlayerConnect(playerid) connected[playerid]=true;
public OnPlayerDisconnect(playerid) connected[playerid]=false;
for(new i; i< MAX_PLAYERS;i++)
{
    if(connected[playerid])
    {
       // do sth here.
    }
}
I did a quick test with code
pawn Code:
new time = GetTickCount();
    for (new i = 0; i < 10000; i++)
    {
        foreach(Player,I)
        {
            item1[I][i]=100;
        }
    }
    printf("Time #1: %d", GetTickCount() - time);
    
    time = GetTickCount();
    for (new i = 0; i < 10000; i++)
    {
        for(new I=0;I<100;I++) { if(connected[I])
        {
                item3[I][i]=300;
        } }
    }
    printf("Time #3: %d", GetTickCount() - time);
Foreach was 104 msec, and mine was 41 msec.

Good idea, must test it too,

Looking forward to hearing from any one else

And how many players did you have on the server during testing?

Re: Loops? - ExoSanty - 15.09.2010

well every millisecond counts, i'll try it to some time

Yerp, I mentioned this as well in a few tests I did some time ago. And I guess that using " if(!connected[i]) continue " is kinda slow as well.

Oh yes, i tested it again and it was like 200x slower. Sorry, my bad, maybe my computer lagged yesterday, because i only checked one result
