An owned NPC is one that only the original creator can manipulate and delete.
An unowned NPC is one that anybody with access to the osNpc* methods and knowledge of the avatar id can manipulate.
This is to correct an oversight I made in the original reimplementation where I mistakenly assumed that avatar IDs could be treated as private.
I am not anticipating that many people were deliberately making use of unowned npcs due to their insecure nature.
If you do need an unowned NPC please call the new overloaded osCreateNpc() function with the option OS_NPC_NOT_OWNED.
This will be documented soon. Options can currently be
OS_NPC_CREATE_OWNED - creates a 'creator owned' avatar that will only respond to osNpc* functions made by scripts owned by the npc creator
OS_NPC_NOT_OWNED - creates an avatar which will respond to any osNpc* functions that a caller has permission to make (through the usual OSSL permission mechanisms).
options is being added to provide better scope for future extensibility without having to add more functions
The original non-options osNpcCreate() function will continue to exist.
The original function suffered from unexpected results due to rounding
errors. An error of only 1 or 2 ulps would cause the code to not detect
a singularity at Y rotation +/- PI/2 and take the non-singularity code
path. The replacement code does not suffer from wildly inaccurate
results at the +/- PI/2 singularity. The check in the code for the
singularity isn't strictly needed, but gives more consistent results
At the singularity, the X and Z rotations add. The if check simply
forces the X rotation to be zero so the entirety of the X+Z rotation is
carried by Z.
Additionally, the test code has been updated to include test cases that
caused the old code to fail. The test algorithm is also updated to
perform a more meaningful test. The original code checked if the values
against expected values. This could fail at +/- PI rotations since a
rotation around an axis by PI causes the identical effect as a rotation
by -PI. The new test code checks that the returned angles can be used
to recreate a quaternion that causes the same rotation.
osParseJSON uses hand-crafted decoding that has two issues
* does not seem to handle top-level JSON lists
* does not seem to handle unicode text
thanks otakup0pe!
from previous commit which sort out which iterator is used are left
intact. A discussion is needed as to what constitutes an avatar vs a
ScenePresence.
the 3 iteration functions so more of them are using the correct
iteration for the action they are performing. The 3 iterators that seem
to fit all actions within OpenSim at this time are:
ForEachAvatar: Perform an action on all avatars (root presences)
ForEachClient: Perform an action on all clients (root or child clients)
ForEachRootClient: Perform an action on all clients that have an avatar
There are still a dozen places or so calling the old
ForEachScenePresence that will take a little more refactoring to
eliminate.
UpdateFlag is now referenced/used only within SOP and SOG. Outsiders are
using ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule on
SOP consistently now. Also started working toward eliminating those
calls to ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule
from outside SOP in favor of just setting properties on SOP and let SOP
decide if an update should be scheduled. This consolidates the update
policy within SOP and the client rather than everywhere that makes
changes to SOP. Some places forget to call update while others call it
multiple times, "just to be sure".
UpdateFlag and Schedule*Update will both be made private shortly.
UpdateFlag is intended to be transient and internal to SOP so it has
been removed from XML serializer for SOPs.
This causes false positives if a simulator has more than 1 region and the current region is 'root' since this sends the command separately to each region and each region has its own XEngine
PARCEL_GROUP, PARCEL_OWNER, ESTATE_MANAGER and REGION_OWNER can be combined with the existing agent uuid option to limit ossl functions to agents and owner classes.
