This stops the npc walking backwards if the target is directly behind.
This means that the npc no longer returns to its original rotation once movement has finished.
If you want this behaviour, please store and reset the original rotation after movement.
This is somewhat to address http://opensimulator.org/mantis/view.php?id=5678
When upgrading the previously child agent to a root, the code was setting the Size parameter on the ODECharacter PhysicsActor.
This in turn reset Velocity, which cause the border stall.
I'm fixing this by commenting out the Velocity = Vector3.Zero lines since they don't appear to play a useful purpose
Attach and detach packets are processed asynchronously when received from a viewer.
Bugs like http://opensimulator.org/mantis/view.php?id=5644 indicate that in some situations (such as attaching/detaching entire folders of objects at once), there are race conditions between these threads.
Since multiple data structures need to be updated on attach/detach, it's not enough to lock the individual collections.
Therefore, this commit introduces a new IScenePresence.AttachmentsSyncLock which add/remove operations lock on.
The code in question is over three years old and just be catching an inconsistency rather than being wholly necessary.
This commit still carries out the check and prints all the previous log warnings but a 'failure' no longer prevents avatar region crossing or teleport, and it doesn't give the client the error message.
This will have some kind of impact on http://opensimulator.org/mantis/view.php?id=5672
This was happening because we were using the source avatar's item IDs in the clone appearance.
Switch to using the asset IDs of attachments instead for NPCs.
The InventoryAccessModule and AttachmentModule had to be changed to allow rezzing of an object without an associated inventory item.
Hopefully goes some way towards resolving http://opensimulator.org/mantis/view.php?id=5653
The approach here, as in other parts of OpenSim, is to return a copy of the list rather than the attachments list itself
This prevents callers from forgetting to lock the list when they read it, as was happening in various parts of the codebase.
It also improves liveness.
This might improve attachment anomolies when performing region crossings.
On making a root agent, we need to reset the ScenePresence.m_movement_flag so that it doesn't remember the
movement registered to the client when it exited the initial region.
If this is remember, then the client avatar movement isn't updated and it appears to stall in mid-air, though this is resolved with a prod/release of any other direction key.
This bug was probably introduced a few weeks ago. Surprised that nobody brought it up.
This is done by introducing a PresenceType enum into ScenePresence which currently has two values, User and Npc.
This seems better than a SaveAttachments flag in terms of code comprehension, though I'm still slightly uneasy about introducing these semantics to core objects
this is to allow walking on prims. it will be up to the script writer to be sure that there is a continuous path.
currently implemented in osNpcMoveToTarget(), but none of this is final.
This doesn't help where the target is a prim surface. In these situations, it might be better to provide manual overrides so the script can control whethre an avatar flys there/lands, etc.
This makes the movement exact. Regression test changed to check avatar reaches exact target.
Also has the nice side effect of making NPC animations continue to work after the first movement (which wasn't working). However, avatar still pauses in mid-stride
Avatar moves and stops. However, will stop in mid stride.
And if the move to position is in the air, avatar will continue to make vain and quite hilarious attempts to take off (but never doing so).
Clearly more work is needed.
This now works again except that it requires a click or avatar mvmt to get going
This is because the ScenePresence.HandleAgentUpdate() method doesn't trigger until the client does something significant, at which point autopilot takes over.
Even clicking is enough to trigger.
This will be improved presently.
This is not used for anything - appearances are always properties of objects with ids (ScenePresence, AgentCircuitData) and just has the potential to get out of sync when the appearance is cloned.
Had to stop using AvatarService for now since it doesn't store baked texture IDs (which is why this was failing).
Also failing because cloning appearance was also cloning the AvatarApperance.Owner field, which we weren't then changing.
Extended TestCreate() to check this.
This now creates an avatar but appearance is always cloudy.
Move doesn't work.
Really, creating an NPC should only involve a ScenePresence rather than doing anything with IClientAPI, since an NPC has no viewer to communicate with!
child agents in neighbor regions. This means you can extend
the view on a simulator beyond the default 3x3 regions.
This uses a region default draw distance and should be
replaced at some point by the avatar specified draw distance.
That will require more careful, dynamic recomputation of child
agents every time the draw distance changes.
WARNING: this is experimental and has known instabilities. specifically
all regions "within site" should be running the same default draw distance
or agents will not be closed correctly.
This restores a RemoveFromPhysicalScene() call in ScenePresence.CheckForBorderCrossing() when the agent has been placed in transit.
If we don't remove the agent from the physical scene, then the method continues to be called via ScenePresence.Update()
until the handover of the client between regions is completed. Since this handover can take more than 1000ms (due to the 1000ms
event queue polling response from the server), this results in the avatar pausing on the border for the entire handover period.
