this is step 2 of 2 of the OpenSim.Region.Environment refactor.
NOTHING has been deleted or moved off to forge at this point. what
has happened is that OpenSim.Region.Environment.Modules has been split
in two:
- OpenSim.Region.CoreModules: all those modules that are either
directly or indirectly referenced from other OpenSim packages, or
that provide functionality that the OpenSim developer community
considers core functionality:
CoreModules/Agent/AssetTransaction
CoreModules/Agent/Capabilities
CoreModules/Agent/TextureDownload
CoreModules/Agent/TextureSender
CoreModules/Agent/TextureSender/Tests
CoreModules/Agent/Xfer
CoreModules/Avatar/AvatarFactory
CoreModules/Avatar/Chat/ChatModule
CoreModules/Avatar/Combat
CoreModules/Avatar/Currency/SampleMoney
CoreModules/Avatar/Dialog
CoreModules/Avatar/Friends
CoreModules/Avatar/Gestures
CoreModules/Avatar/Groups
CoreModules/Avatar/InstantMessage
CoreModules/Avatar/Inventory
CoreModules/Avatar/Inventory/Archiver
CoreModules/Avatar/Inventory/Transfer
CoreModules/Avatar/Lure
CoreModules/Avatar/ObjectCaps
CoreModules/Avatar/Profiles
CoreModules/Communications/Local
CoreModules/Communications/REST
CoreModules/Framework/EventQueue
CoreModules/Framework/InterfaceCommander
CoreModules/Hypergrid
CoreModules/InterGrid
CoreModules/Scripting/DynamicTexture
CoreModules/Scripting/EMailModules
CoreModules/Scripting/HttpRequest
CoreModules/Scripting/LoadImageURL
CoreModules/Scripting/VectorRender
CoreModules/Scripting/WorldComm
CoreModules/Scripting/XMLRPC
CoreModules/World/Archiver
CoreModules/World/Archiver/Tests
CoreModules/World/Estate
CoreModules/World/Land
CoreModules/World/Permissions
CoreModules/World/Serialiser
CoreModules/World/Sound
CoreModules/World/Sun
CoreModules/World/Terrain
CoreModules/World/Terrain/DefaultEffects
CoreModules/World/Terrain/DefaultEffects/bin
CoreModules/World/Terrain/DefaultEffects/bin/Debug
CoreModules/World/Terrain/Effects
CoreModules/World/Terrain/FileLoaders
CoreModules/World/Terrain/FloodBrushes
CoreModules/World/Terrain/PaintBrushes
CoreModules/World/Terrain/Tests
CoreModules/World/Vegetation
CoreModules/World/Wind
CoreModules/World/WorldMap
- OpenSim.Region.OptionalModules: all those modules that are not core
modules:
OptionalModules/Avatar/Chat/IRC-stuff
OptionalModules/Avatar/Concierge
OptionalModules/Avatar/Voice/AsterixVoice
OptionalModules/Avatar/Voice/SIPVoice
OptionalModules/ContentManagementSystem
OptionalModules/Grid/Interregion

|
||||
* WorldCommModule
|
||||
*
|
||||
*
|
||||
* Holding place for world comms - basically llListen
|
||||
* function implementation.
|
||||
*
|
||||
* lLListen(integer channel, string name, key id, string msg)
|
||||
* The name, id, and msg arguments specify the filtering
|
||||
* criteria. You can pass the empty string
|
||||
* (or NULL_KEY for id) for these to set a completely
|
||||
* open filter; this causes the listen() event handler to be
|
||||
* invoked for all chat on the channel. To listen only
|
||||
* for chat spoken by a specific object or avatar,
|
||||
* specify the name and/or id arguments. To listen
|
||||
* only for a specific command, specify the
|
||||
* (case-sensitive) msg argument. If msg is not empty,
|
||||
* listener will only hear strings which are exactly equal
|
||||
* to msg. You can also use all the arguments to establish
|
||||
* the most restrictive filtering criteria.
|
||||
*
|
||||
* It might be useful for each listener to maintain a message
|
||||
* digest, with a list of recent messages by UUID. This can
|
||||
* be used to prevent in-world repeater loops. However, the
|
||||
* linden functions do not have this capability, so for now
|
||||
* thats the way it works.
|
||||
* Instead it blocks messages originating from the same prim.
|
||||
* (not Object!)
|
||||
*
|
||||
* For LSL compliance, note the following:
|
||||
* (Tested again 1.21.1 on May 2, 2008)
|
||||
* 1. 'id' has to be parsed into a UUID. None-UUID keys are
|
||||
* to be replaced by the ZeroID key. (Well, TryParse does
|
||||
* that for us.
|
||||
* 2. Setting up an listen event from the same script, with the
|
||||
* same filter settings (including step 1), returns the same
|
||||
* handle as the original filter.
|
||||
* 3. (TODO) handles should be script-local. Starting from 1.
|
||||
* Might be actually easier to map the global handle into
|
||||
* script-local handle in the ScriptEngine. Not sure if its
|
||||
* worth the effort tho.
