It is GangZoneCreate(Float:minx, Float:miny, Float:maxx, Float:maxy) so it should be

pawn Код:

SafeZone = GangZoneCreate(581.7188, 676.0, 2972.0, 2930.0);

For easier usage you should always use the same syntax

pawn Код:

IsPlayerInArea(playerid, Float: minx, Float: miny, Float: maxx, Float: maxy) {
    new
        Float: X,
        Float: Y
    ; // a little optimisation
    return GetPlayerPos(playerid, X, Y, Float: playerid) && (minx <= X <= maxx) && (miny <= Y <= maxy);
}

And now OnPlayerUpdate

pawn Код:

//OnPlayerUpdate
    if(IsPlayerInArea(playerid, 581.7188, 676.0, 2972.0, 2930.0)) {
        ResetPlayerWeapons(playerid);
    }
