I tried that Vince, but I don't know how to do it.

Would it be:

pawn Код:

command(cap, playerid, params[])
{
    if(IsPlayerInAnyVehicle(playerid))
    {
        new Float:x, Float:y, Float:z, Float:cX, Float:cY, Float:cZ;
        GetVehiclePos(GetPlayerVehicleID(playerid), x, y, z);
        GetVehicleModelInfo(GetVehicleModel(GetPlayerVehicleID(playerid), VEHICLE_MODEL_INFO_PETROLCAP, cX, cY, xZ);
        SetPlayerCheckpoint(playerid, x+cX, y+cY, z+cZ, 1.0);
    }
    else return SendClientMessage(playerid, WHITE, "You aren't in a vehicle.");
}
