The '//' are simply comments. Also, Jay's way should work, but I dont see why you need an 'else if' return statement underneath the public function.

pawn Код:

public IsAtDealership(playerid)
{
    if(IsPlayerConnected(playerid))
    {
        if(PlayerToPoint(20,playerid,883.2045,-1664.6119,13.0577) || PlayerToPoint(20,playerid,2155.4507,-1166.2189,23.3321) || PlayerToPoint(20,playerid,2126.8904,-1139.7179,24.7564) || PlayerToPoint(20,playerid,1667.0667,-1055.6960,23.3974) || PlayerToPoint(20,playerid,549.1564,-1282.5328,16.7654) || PlayerToPoint(20,playerid,1085.9401,-1754.1245,12.8987) || PlayerToPoint(20,playerid,1992.6484,-1278.7939,23.3309) || PlayerToPoint(20,playerid,1838.1348,-1864.8322,13.3828))
        {
            return 1;
        }
    }
    return 0;
}

If you simply want when the player is at those positions, simply create another public function.

pawn Код:

forward YourFunction(playerid)
public YourFunction(playerid)
{
    if(IsPlayerConnected(playerid))
    {
        if(PlayerToPoint(20,playerid,2057.9741,-1913.3403,13.0569) || PlayerToPoint(20,playerid,2516.9893,-1529.9097,23.0431) || PlayerToPoint(20,playerid,2425.1406,-1229.1522,24.4736) || (PlayerToPoint(20,playerid,1658.9684,-1020.9565,23.8984) || PlayerToPoint(20,playerid,1662.3169,-1120.3746,23.9063) || PlayerToPoint(20,playerid,2167.3503,-1801.1819,13.1062) || PlayerToPoint(20,playerid,1942.7716,-2136.1067,13.1914) || PlayerToPoint(20,playerid,1263.4960,-1813.7924,12.9131))
        {
            return 1;
        }
    }
    return 0;
}

For future references, use the [PAWN] tags instead of the [CODE]. This way, we can see the code much 'clearer' and can respond easily.
