Well, example with ZCMD

pawn Код:

stock GiveLoopWeapon(weapon_id)
{
     for (new p = 0; p < MAX_PLAYERS; p++) { GivePlayerWeapon(p, weapon_id, 9999); }
}

CMD:sawntoall( playerid, params[ ] )
{
    GiveLoopWeapon( 26 ); 
    return 1;
}

Gives sawnoffs to everyone.

EDIT: In loops, to reduce lag, you should use IsPlayerConnected.

pawn Код:

stock GiveLoopWeapon(weapon_id)
{
     for (new p = 0; p < MAX_PLAYERS; p++) if(IsPlayerConnected(p)) { GivePlayerWeapon(p, weapon_id, 9999); }
}
