Well the steamer has playerid parameter so you could do this

At top with other variables

pawn Код:

enum Stunts
{
    stunt1,
    stunt2,
    stunt3
    //and so on
};

new pCheckpoint[MAX_PLAYERS][Stunts];

Then where you need to create the players checkpoint

pawn Код:

pCheckpoint[playerid][stunt1] = CreateDynamicCP(x,y,z,7.0,-1,-1,playerid,70.0);//note it wll only be  created for 'playerid'

Then finally

pawn Код:

public OnPlayerEnterDynamicCP(playerid, checkpointid)
{
    if(checkpointid == pCheckpoint[playerid][stunt1])
    {
        //do stuff here
        DestroyDynamicCP(pCheckpoint[playerid][stunt1]);
    }
    return 1;
}

That might work
