| 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 OpenSim 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, int 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, 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.
