static objects by more restrictive selection of objects that collide
with static objects.
Rename collision mask fuctions from 'filter' to 'group' so it is clear
what is being set.
Rename BulletSimAPI.SetCollisionFilterMask() to SetCollisionGroupMask to match above.
Restore passing of time step to linear and angular motion component routines.
Use buffering vehicle physical parameter get/set routines consistantly.
Make range enforcement clearer by using ClampInRange() function for parameter setting.
Remove commented out experimental vehicle calculations.
This reduces base memory churn of every client connection, improving the garbage collection situation.
The effect is a significant portion of base load (an avatar standing still on a completely blank island)
but will probably still be swallowed up by other memory use on active regions.
Tests have shown no noticeable impact on speed of processing incoming packets, though setting remains
in case a switch back is needed.
Setting this to false will block all restart requests from the viewer even if they are otherwise legitimate.
One use is to block region restarts if necessary whilst restart functionality remains buggy or triggers bugs in modules,
though these should be fixed as soon as practicable.
Default is true, as has been the case historically.
Simple attempt to make avatars better shaped.
Replace parameter 'avatarCapsuleRadius' with 'avatarCapsuleWidth'
and 'avatarCapsuleDepth'.
More tweeking to avatar height calculation. A little better but
short avatar's feet are above the terrain and tall avatar's feet
are a little below the ground.
nant_0.91~alpha2+dfsg-3_all.deb in Ubuntu 12.04 and earlier actually ignored these due to a bug
However, nant 0.92~rc1+dfsg-2 in Ubuntu 12.10 fixes this bug (possibly https://github.com/nant/nant/pull/39).
Which makes nant time-consumingly copy these files when the aren't actually used.
Tested removal of <copy> on both nant 0.91 and nant 0.92
Will be submitting this patch to prebuild project for comment though I suspect there's nobody there to pay attention.
This allows a closed grid to delete asset types other than maptile remotely.
Only operational if AllowRemoteDelete = true also.
Defaults to false - do not enable if anybody other than you can make asset service requests.
This is because macosx mono is 32-bit and this can't p/invoke 64-bit binaries.
However, the reverse is also true.
If OpenSimulator stops working for you then please complain! Long term alternative is probably to build a fat binary with both architectures.
This retrieves and caches information from the PresenceService to only send messages to online users.
This is reported to much improve performance for large groups where most users are offline.
Cache is 20 seconds to balance requests against users not receiving messages until cache updates.
This is an alternative to an approach where login/logout notification is sent directly from simulator to groups service.
However, I'm not convinced that this PresenceService approach is actually better. Needs more thought.
Even when an avatar is standing still, it's sending in a constant stream of AgentUpdate packets that the client creates new UDPPacketBuffer objects to handle.
This option pools those objects. This reduces memory churn.
Currently off by default. Works but the scope can be expanded.
Rearrangement and cleanup of shape collection code. Much more readable.
Enabling and use of collision filters and masks.
Addition of ID to body creation BulletSimAPI calls so always set in
shape for collision reporting.
Change default of ShouldSplitSimulationIslands and ShouldRandomizeSolverOrder
from 'false' to 'true'. When 'false', this suppresses NO_CONTACT_RESPONSE
which makes volume detect fail.
This controls how many undo steps the simulator will store for each prim.
Default is now 20 rather than 5 as it briefly was.
The default number could be increased through this is a memory tradeoff which will scale with the number of prims in the sim and level of activity.
