When I try to start Vice City computer when first loading screen appears, computer just restarts. With other games like San Andreas or III everything works fine. I have reinstalled VC 4 times, previously (before windows xp reinstall) all was ok.

code:

@ OnGameModeInit: SetTimer("Speed",250,1);

public Speed()
{
for(new i = 0; i <= USERCOUNT; i++)
    {
        if(IsPlayerConnected(i))
{
new Float:x, Float:y, Float:z, distance,result,resultx[256];
    x=PlayerInfo[i][PosX];
y=PlayerInfo[i][PosY];
z=PlayerInfo[i][PosZ];
distance=GetDistance(i, x, y, z);
result=distance*6;
format(resultx,256,"%dkm/h",result);
GameTextForPlayerBottom(i,resultx);

new Float:x2,Float:y2,Float:z2;
GetPlayerPos(i,x2,y2,z2);
PlayerInfo[i][PosX]=x2;
PlayerInfo[i][PosY]=y2;
PlayerInfo[i][PosZ]=z2;

}

}
}

but function is not working well, it needs improvements.
sorry for my english.

I need help with GetPlayerSpeed function, i have no idea how can i do this.

I need that for my server script, i heard something about sending rcon command, would that work, if yes how can i do that?
