Well, I saved two different points that I need to enter comand, but the checkpoint only works on one of the points, my setup is as follows:
IF_IM_NEAR
AddStaticVehicle(560,1960.4465,-2625.7297,13.2513,179.4885,33,0); // aircar
THEN_SAY
/carregar
IF_IM_NEAR
AddStaticVehicle(592,1480.0787,1792.0142,12.0310,0.1506,1,1); // airdes
THEN_SAY
/descarregar
