* The broken avatar may not be able to move, but it won't stop simulate from pressing on now. And, the simulator will try to destroy the avatar's physics proxy and recreate it again... but if this is what I think it is, it may not help.
* This causes time to be counted in ODECharacter and, when a collision occurs, the physics scene will report the collisions only if the the difference of last time it reported the collisions from now was more then the set ms.
* This is cool because the time accrues while collisions are not taking place and when they do take place again, you get an immediate update.
Eliminate dynamic capsule wobble. Instead introduce a small, fixed
tilt, and allow the tilt to rotate with the avatar while moving; the
tilt always faces away from the direction of avatar movement. The
rotation while moving should eliminate direction-dependent behavior
(e.g. only being able to climb on top of prims from certain directions).
Falling animation is still too frequently invoked.
Ideally the tilt should be completely eliminated, but doing so
currently causes the avatar to fall through the terrain.
This fix re-introduces a small tilt into the capsule to prevent
avatar falling through terrain. Re-introduction of the tilt means
that some direction-dependent behavior when walking over prims, but
I have tried to minimize this.
Additionally this commit allows the capsule to wobble slightly when
being pushed around the terrain. This should make walking over prims
easier, as the capsule can wobble and glide diagonally over the prim's
edge, instead of rigidly being stopped vertically against the prim's
face.
Set av_capsule_tilted to false in opensim.ini. Default is true, so there is
no change in avatar behavior (and no breaking of existing content which
relies on the tilted capsule).
This commit straightens up the avatar capsule so it behaves consistently
(e.g. same collision behavior against prims regardless of which direction
the avatar is coming from; ability to fit through narrow doorways).
Please note this introduces other side effects which have not been fixed.
In particular:
* The avatar frequently falls through the terrain if it is not flat, though
the avatar behaves pretty well on flat terrain. This requires investigation
of the ode terrain collider.
* The apparent foot position of the avatar with respect to the ground
is changed. This requires investigation of the avatar height/capsule height.
Please consider this as work in progress.
* WebStatsModule doesn't crash on restart. GodsModule doesn't crash when there is no Dialog Module. LLUDPServer doesn't crash when the Operation was Aborted.
* ODEPlugin does 'Almost NaN' sanity checks.
* ODEPlugin sacrifices NaN avatars to the NaN black hole to appease it and keep it from sucking the rest of the world in.
* Now validating input to the Physics scene and warning when something is awry.
* This should help nail down that Non Finite Avatar Position Detected issue.
* This may help one of the symptoms or mantis 3363 , however it probably won't solve the occasional NonFinite Avatar Position detected.. issues that some people see. That is probably an entirely different issue(NaN).
llSetHoverHeight() should not clamp the x/y position of an object the way MoveTo does,
and it should recalculate the absolute height to hover at as an object moves to reflect
the current ground/water height under it.
Correctly implementing required adjusting the Physics interfaces and implementing at
the physics plug-in level. The attached is a patch that correctly implements
llSetHoverHeight() including updates to the ODE physics plug-in.
* Added log4net dependency to physxplugin in prebuild.xml.
* Added missing m_log fields to classes.
* Replaced Console.WriteLine with appropriate m_log.Xxxx
* Tested that nant test target runs succesfully.
* Tested that local opensim sandbox starts up without errors.
* If you log-in while the simulator is starting up, you won't be able to move and the sim stats will say 0 FPS, and 0 Physics Frames and you may see only terrain. Once the sim finishes starting up, it'll all resume as normal.
* Warning! Physics API change. This means that the NBodySimulation needs to be updated!
* PhysicsActor -> void SetVolumeDetect(int) needs to go into classes that use PhysicsActor as their base class.
* Implement the linear impulse portion of llPushObject. We should have a lsl compatible implementation of that portion of the push. Angular.. well. still have yet to implement a torque accumulator.
* llPushObject respects the region and parcel settings for Restrict Push, it also respects GodMode as is defined in the LSL spec.
* If you are hosting many regions on a single instance, you will probably notice a decrease in region startup time and maybe a slight increase in performance.
* Single regions won't notice anything different
* This is a HUGE OMG update and will definitely have unknown side effects.. so this is really only for the strong hearted at this point. Regular people should let the dust settle.
* This has been tested to work with most basic functions. However.. make sure you back up 'everything' before using this. It's that big!
* Essentially we're back at square 1 in the testing phase.. so lets identify things that broke.
* Currently if you apply that to only one or two axis you get unpredictable and sometimes explosive results.
* Three axis works well enough to play with it anyway. More work is needed here.
* Fixed an incorrectly named method in ODE.NET
* It doesn't generate at_target events, because they don't exist yet in the script engine.
* The Tau is different, however, compatible with scripts I tested.
* Not perfect... but pretty good.
* Added osSetPrimFloatOnWater(BOOL) to make Physical prim float at the water level.
* osSetPrimFloatOnWater(TRUE); or osSetPrimFloatOnWater(FALSE);
* By default, prim do not float at the water level.
* More work is needed on the floating, but it's a start.
* To play with this you must link your prim before setting it physical, otherwise they won't link in the physics engine properly. This will also be fixed.
* Currently the linked prim are extremely unstable because I have yet to implement combining of forces with the same normal. This will also be fixed. In fact, the whole PhysicsActor, ODEPrim relationship will be reworked to consider groups from the get-go.
* This implementation is better then it crashing your sim, so I'm commiting it for now.
* When you select a physical prim, it stops while you've got it selected.
* When you move or alter a prim in some manner, it doesn't become collidable until you de-select it
* When you select a prim, it doesn't become temporarily 'phantom' until you make some change to it while it's selected. (this prevents accidental selections in prim floor from causing it to go phantom on you(but don't move it or you'll fall))
* There's one major difference, and that's a physical object won't stop if you don't have permission to edit it. This prevents people who don't have edit permissions on a prim from stopping it while it's moving.
* Updated the ode.dll for windows with a more reasonable stack space reserve. Linux users will need to type ulimit -s 262144 before starting up OpenSimulator if using Physical Prim to protect against stack collisions. or run the included ./bin/opensim-ode.sh to start up OpenSimulator in ODE mode.
* Added internal collision score and am keeping track of 'high usage' prim.
* Tweaked collisions some more
* Tested up to 460 physical prim in extremely close quarters (which was previously impossible in OpenSim). After 460 in tight quarters, physics slows down enough to make it hard to do any moving, however.. non physics things still work, such as logging on to the simulator, etc.
* Just to give you an idea of the difference .. previous ODE_STEPSIZE was 0.005f - 1000/5 = 200fps - 10 substeps with fallback to 5 substeps when things get slow
* *nix avatar may fall over again, *sorry*
* Set the avatar's radius to 0.37m, I think this gives the *best* balance between spaces the avatar can fit, and the ability to climb steps
* Fixed a few things
* Tweaked some more
* Played with gravity (-9.8m/s)
* Cleaned up copyright notices in AssemblyInfo.cs's
* Added Copyright headers to a bunch of files missing them
* Replaced several common string instances with a static constant to prevent reallocation of the same strings thousands of times. "" -> String.Empty is the first such candidate.
* Did some goofy math undoing in the Sim Stats Reporter
* More reduction to the amount of calls per second to UnManaged ODE code
* Added a significant amount of comments to ODE
** - avatar can navigate stairs better now
** - avatar can land without shooting into the air
** - excessive collisions with the ground are tempered somewhat and should only shoot the avatar up 20m instead of 200m
** - Try Catched a TextureDownloadModule.cs array out of bounds error with a report that causes it not to crash the sim, however it reports a few important items for tracking it down.
* Fixes:
* -- duplicating Active physical object causes objects to explode in opposite directions
* -- Rezzing objects too close to you avatar causes avatar to shoot around in odd directions
* Vanity
* Exposed the mass as a PhysicsActor read only property (so scripts can get at it - hint hint -)
* Hollow and Path Cuts affect the prim mass (all Hollow Types are supported in this calculation (sphere,square,triangle))
* Prim no longer sink into the ground.
