new SmokeWait[MAX_PLAYERS];
forward SmokeTimer(playerid);

Where your /smoke command is:

pawn Код:

if(SmokeWait[playerid] == 1) // If player has been smoking lately
{
    SendClientMessage(playerid, 0xFFFFFFFF, "You have to wait before smoking again");
    return 1;
}
SmokeWait[playerid] = 1; // Set this variable to 1 so player can't smoke next time 
SetTimerEx("SmokeTimer", 120000, false, "i", playerid); // Timer to clear the variable after 2 minutes so player can smoke again

pawn Код:

public SmokeTimer(playerid)
{
    SmokeWait[playerid] = 0; // Now player can smoke again
}
