Code:
EVENT_COMPASS_CHANGE (eventCode,
int index,
MapDisplayPinType pinType,
string pinDescription,
float distance,
bool newAddition*
)
Something like that. If there were x/y_coordinates or directionFacing someone could map the memory to write botting applications.
* true when pin/marker becomes visible and false when a pin/marker is no longer visible (false still returns the index)
