[Think]

unless you want it that you cant spam 3 different commands, than you could just do this:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext)
{
    spam[playerid]++;
    if(spam[playerid] >=3) {
       SendClientMessage(playerid, RED, "Stop spamming wait 5 sec.");
       SetTimerEx("antispam", 30000, false, "i", playerid);
    }
   return 0;
}
