i wanna check something if the player want to enter the car as a driver i did something like that:
if(IsAnFbiCar(newcar))
{
if(PlayerInfo[playerid][pLeader] == 2||PlayerInfo[playerid][pMember] == 2)
{
SendClientMessage(playerid, COLOR_WHITE,"Welcome to FBI vehicle.");
}
else
{
RemovePlayerFromVehicle(playerid);
TogglePlayerControllable(playerid, 1);
SendClientMessage(playerid, COLOR_WHITE,"You don't have keys of this vehicle.");
}
}

but it's not good, how can i add a check after they press ENTER or F.
