You have to use arrays.

At top:

pawn Код:

new Checkpoint[MAX_PLAYERS];

pawn Код:

SetPlayerCheckPoint(stuff);
Checkpoint[playerid] = 1;

pawn Код:

public OnPlayerEnterCheckpoint(playerid)
{
    if(Checkpoint[playerid] == 1)
    {
        // stuff
        PlayerInfo[playerid][Checkpoint] = 0;
    }
    return 1;
}
