| Notes
|
Some more useful info:
- NPC stands for Non-Player Character.
- You can clone an appearance from a saved appearance notecard name or UUID, or from the UUID of an avatar logged into the same region or sim.
- You can create and load appearance notecards with the following functions: osOwnerSaveAppearance, osAgentSaveAppearance, osNpcLoadAppearance, osNpcSaveAppearance.
- In current OpenSimulator development code (from commit c4972e77 on Thu Jan 12 2012), an overloaded version of osNpcCreate() has been added.
- This has the signature key osNpcCreate(string firstname, string lastname, vector position, string cloneFrom, integer options).
- The options field can be either OS_NPC_CREATOR_OWNED or OS_NPC_NOT_OWNED.
- OS_NPC_CREATOR_OWNED will create an 'owned' NPC that will only respond to osNpc* commands issued from scripts that have the same owner as the one that created the NPC.
- OS_NPC_NOT_OWNED will create an 'unowned' NPC that will respond to any script that has OSSL permissions to call osNpc* commands.
- Example: "key npc = osNpcCreate("ImYour", "Clone", npcPos, "appearance", OS_NPC_CREATOR_OWNED);"
- The existing osNpcCreate() function without the options field will continue to exist.
- From git master commit 3b59af22 on Friday Jan 13 2012 (after the OpenSimulator 0.7.2 release), the avatar created by the existing osNpc* function without the options parameter will create an 'owned' NPC rather than an 'unowned' one. Please see the discussion above for information on these terms. This is a hopefully rare case where the behaviour of an existing function changes slightly. If you continue to need an 'unowned' NPC, please use the OS_NPC_NOT_OWNED option described above.
- Use OS_NPC_SENSE_AS_AGENT option if you would like for the created NPC to be able to be detected via a sensor and want to maintain llSensor() compatibility with type AGENT.
- OS_NPC_OBJECT_GROUP with it the npc will be created with the group of the object with the script, if that object owner is member of that group. This should allow parcel access by group to work now, and not much else. The group Title will also be set, it the region option NoNPCGroup is not active.
