Warzone does not process the return value of this event.
Notes
This event is triggered when a transport arrives on the map at the location set by startTransporterEntry(). It will then proceed to (the nearest?) landing zone.
This event is useful for determining if the LZ is safe, and if not sending the transport back to base.
If the transport goes on to successfully land, eventTransporterLanded() will be triggered.
Example
function eventTransporterArrived() {
playSound("pcv442.ogg"); // Reinforcements landing
}
