}

and make vmcheckpoints 1D.

also,you can make it much "pro":

pawn Код:

new const Float:checkpoints[][]=
{
{-2019.8148,-145.6181,35.320},
{-2021.3827,-137.9689,35.3015},
{-2022.2931,-172.4966,35.3203}
}
if(vmcheckpoints[playerid] >= 0)
{
    DestroyDynamicRaceCP(checkpointid);
    if(vmcheckpoints[playerid]!=sizeof(checkpoints))
    {
        SetPlayerCheckpoint(playerid,checkpoints[ vmcheckpoints[playerid] ][0],checkpoints[ vmcheckpoints[playerid] ][1],checkpoints[ vmcheckpoints[playerid] ][2] , 6);
        CreateDynamicRaceCP(0,checkpoints[ vmcheckpoints[playerid] ][0],checkpoints[ vmcheckpoints[playerid] ][1],checkpoints[ vmcheckpoints[playerid] ][2]
        ,checkpoints[ vmcheckpoints[playerid]+1][0],checkpoints[ vmcheckpoints[playerid]+1][1],checkpoints[ vmcheckpoints[playerid]+1][2], 3, 0, 0, playerid, 200.0);//1
        vmcheckpoints[playerid]++;
        new string[30];format(string,30,"(%d/%d)",vmcheckpoints[playerid],sizeof(checkpoints));
        GameTextForPlayer(playerid, string, 3000, 3);
    }
    return 1;

}
