Проблема с чекпоинтами

[Jack_Wilshere]

в действии диалога:

SetPlayerRaceCheckpoint(playerid,2,-2055.235107,-94.230751,34.993179,0,0,0,3.0);
SetPVarInt(playerid,"LessonCheck", 1);

И действие чекпоинтов:

public OnPlayerEnterCheckpoint(playerid)
{
if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
{
if (GetPVarInt(playerid,"Lesson") == 1)
{
// SetPVarInt(playerid,"LessonCheck", (GetPVarInt(playerid,"LessonCheck") == 25) ? (0) : (GetPVarInt(playerid,"LessonCheck")+1));
switch(GetPVarInt(playerid,"LessonCheck"))

Проблема в том,что когда нам создался первый чекпоинт(в действии диалога),при наезде на него ничего не происходит!
