of race conditions and, especially, race conditions when an object is
removed and quickly re-added to a scene.
This hopefully reduces the occurance of problems when avatars TP within
a region -- the main problem being the loss of collisions.
initialization race conditions reported in Mantis 6792.
When a region is initializing it seems that the prim initialization code
can be interrupted part way through then taints are processed for
prims that are not completely there.
This commit addresses the following issues were causing velocity to be set to 0 on the new region, disrupting flight in particular
* Full avatar updates contained no velocity information, which does appear to have some effect in testing.
* BulletSim was always setting the velocity to 0 for the new BSCharacter. Now, physics engines take a velocity parameter when setting up characters so we can avoid this.
This patch applies to both Bullet and ODE.
This involves making PhysicsActor.PIDActive get as well as set.
On physics components that don't implement this (all characters and some phys engines) we return false.
Add proxy cache clearing when some properties are changed. This fixes
a problem where objects would stop colliding of they were moved
with setPosition mulitple times.
Normally, avatar motion is zeroed if colliding with a stationary object so
they don't slide down hills and such. Without volume detect check this also
allowed avatars to stand on volume detect objects and to have some jiggling
when they were in the volume detect object. This commit fixes both.
don't happen until the object is completely initialized.
This fixes the problem of doing a teleport while the simulator is running.
The destruction of the physical object while the engine is running means
that the physics parameter update would overwrite the new position of the
newly created avatar.
is not with a volume detect object.
This fixes a problem of avatars trying to step over a volume detect object
that they collide with. This appeared as the avatar popping up as it started
to step up but then continuing on since the object wasn't physically interacting.
into the linkset implementation classes.
Add HasSomeCollision attribute that remembers of any component of
a linkset has a collision.
Update vehicle code (BSDynamic) to use the HasSomeCollision in place of
IsColliding to make constraint based linksets properly notice the ground.
Add linkset functions to change physical attributes of all the members
of a linkset.
Default off, for the moment, until more testing.
Add separate thread and center-of-mass flags to OpenSimDefaults.ini.
Clean up comments in OpenSimDefaults.ini.
There is still some overshoot but mostly fixes Mantis 6693.
Fix bug where moveToTarget was active for non-physical objects
and while selected.
Fix bug where move target was not getting changed if the script
changed the target during a move.
funny unit that is 100 times real density (default 1000).
Fix avatar drifting slowly when stationary flying.
Fix for physical prims getting corrected for being under terrain when it was
just its geometric center that was below terrain.
Add PreUpdatePropertyAction allowing plugable modifiction of phys
parameters returned from Bullet.
Fix an exception setting GravityMultiplier on initialization.
Update DLLs and SOs for good measure (no functional change).
on a moving object.
Rearrange pre/post action subscription code to put more in locks.
Add meshmerizer params to BulletSimTestUtil scene creation (and fix line endings).
Rebuilt version of DLLs and SOs with cleaned up code and no profiling for sure.
