make it like that:

pawn Код:

new InDuel[MAX_PLAYERS];

And then in your duel command add:

pawn Код:

InDuel[playerid] = 1;

And then:

pawn Код:

public Minigunz()
{
    if(InDuel[playerid] == 1) return 0;
    for(new i; i < MAX_PLAYERS; i++) if(IsPlayerConnected(i))
    {
        GivePlayerWeapon(i, WEAPON_MINIGUN, MINIGUN_AMMO);
        GameTextForPlayer(i, "~w~Minigun~n~~r~Madness!", 2000, 3);
    }
    DelayTimer = SetTimer("StopMinigunz", SINTERVAL, 0);
    return 1;
}

FIXED !
