Personally, I use:

pawn Код:

new Checkpoint[MAX_PLAYERS];

And I do this:

pawn Код:

cmd(bus, playerid, params[])
{
Checkpoint[playerid] = 1;
return 1;
}

and..

pawn Код:

OnPlayerEnterCheckpoint(playerid)
{
if(Checkpoint[playerid] == 1)
{
//blah
}
else if(Checkpoint[playerid] == 2)
{
//blah
}
//..et cetera
return 1;
}
