[Opensim-users] Does OpenSim fully support Linden Script?

[Wade Schuette]

Kay, the short answer is, "No".   LSL is not fully supported by the 
default settings of the OpenSim platform. In particular road vehicles 
have been difficult to get to operate at all,  and flying vehicles, 
well, I gave up on those a year ago, but since then ODE has become the 
new default.

Status of various LSL scripting functions is on this page:
http://opensimulator.org/wiki/LSL_Status/Functions

The longer answer is "On the other hand...".   OpenSim new default 
physics engine ("OpenDynamicsEngine - ODE) can be BETTER than Second 
Life's version of Havok4.

There's investigation of "ninja physics" to include actual axles and 
hinges and physics that work, among other things.

Speaking as an undergraduate physics graduate,  the physics in Second 
Life is ... bizarre.  Whoever implemented it didn't really grasp the 
basic principles of dynamics, so it's all sort of a huge kludge to get 
it to function.

The OpenSimulator vehicle script page
http://opensimulator.org/wiki/Vehicles#VEHICLE_Scripting_Examples
was last updated when work was suspended October 24, 2009 when she ran 
into a show-stopper obstacle.

BUT, the OSgrid forum lists a number of more current scripts, and was 
last updated in 2011.

I guess it's time to give those a try!
