Version history

|
- 1.0.0 initial vbersion

|
- 1.1.0 added flag manipulation options

|
no negative agl on announcement
|
|
silent attribute

f!, cargoReceived!

- 1.2.1 cargoMethod
|
|
|
|
|
|
CargoReceiver is a zone enhancement you use to be automatically
|
|
notified if a cargo was delivered inside the zone.
|
|
It also provides BRA when in range to a cargo receiver
|
|
|
|
*** EXTENDS ZONES
|
|
|
|
Callback signature:
|
|
cb(event, obj, name, zone) with
|
|
- event being string, currently defined: 'deliver'
|
|
- obj being the cargo object
|
|
- name being cargo object name
|
|
- zone in which cargo was dropped (if dropped)
