How can I do this? Here's the code.
pawn Код:
public OnPlayerEnterRaceCheckpoint(playerid)
{
    foreach(Player, i)
    {
        if(PlayerInQuadRace(i))

            new string[128];
            if(IsQuading[i] == 1)
            {
                DisablePlayerRaceCheckpoint(i);
                format(string, sizeof(string), "~n~~n~~n~~n~~n~~n~~n~~n~~n~~g~QUAD RACING~n~~r~Checkpoint: ~w~%d/15 ~r~Leader: ~w~%s", quad1, Name(Winner));

That is indeed some really inefficient coding.

To detect the position, you will need to do a few things: First, loop through all players to see who's the furthest in the race. If two or more players are at the same checkpoint, measure the distance between that checkpoint and each player separately to determine who's closer.

pawn Код:
stock Float:GetDistanceBetweenPoints(Float:x1, Float:y1, Float:z1, Float:x2, Float:y2, Float:z2)
{
    x1 -= x2;
    y1 -= y2;
    z1 -= z2;
    return floatsqroot((x1 * x1) + (y1 * y1) + (z1 * z1));
}

I'm hopeless with coords, what would I put in the Float1 etc? I need to learn someday. Thanks!

I took some time to fix up your function, making it cleaner

pawn Код:
new Float:QuadPositions[][6] = {
{ -2207.9607,-2091.2292,76.7566, -2119.5029,-1952.6241,99.1260 },

{ -2126.6528,-1902.5149,113.9288, -2221.3625,-2050.3083,119.3457 },
{ -2221.3625,-2050.3083,119.3457, -2429.5652,-2087.6035,122.6606 },
{ -2429.5652,-2087.6035,122.6606, -2522.4373,-1977.1553,172.0493 },

};

public OnPlayerEnterRaceCheckpoint(playerid)

            SetPlayerRaceCheckpoint(playerid, 0, QuadPositions[IsQuading[i]][0], QuadPositions[IsQuading[i]][1], QuadPositions[IsQuading[i]][2], QuadPositions[IsQuading[i]][3], QuadPositions[IsQuading[i]][4], QuadPositions[IsQuading[i]][5], 5.0);
            GameTextForPlayer(i, string, 5355234364634634, 3);
