SP still has an implementation but this is now just a public method on SP rather than an abstract one in EntityBase.
No point making the code more complex until it actually needs to be,
Even though we don't use these on rez they are still present after an unlink, after which selecting them causes various viewers to crash
Hopefully really does address http://opensimulator.org/mantis/view.php?id=5664
It's never possible for SOG to have no RootPart, except in the first few picosends of the big bang when it's pulled from region persistence or deserialized
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 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.
I think (ha ha) this largely fixes undo, except for the fact that rotation a set of prims with 'edit linked parts' selected doesn't quite work properly (though this works fine if the checkbox isn't selected).
Also, the double undo bug for resize is still present.
Redo might be incredibly buggy, haven't even looked at that yet.
The only obviously broken things right now are the undo of the position of just a root prim (stays in place) and the fact that resizes need two undoes.
This involves implementing a boolean in UndoState to signal whether the undo needs to be done for an entire group/linkset or just a single prim
Resizing individual components of linksets is still dodgy.
Resizing still has to be down twice, since for some reason the client is sending two multiobjectupdate packets on every resize except the very first. This applies to single prims and linksets. Need to look into this.
Undo rotation and position appear to be working.
Resizing a single prim appears to be working, though the undo has to be done twice.
Resizing a group of prims still does not work properly - possibly because in the UndoState we don't store a knowledge of when we're resizing a whole group rather than individual prims.
This needs to be addressed.
Also fiddle a bit with undo. This is not currently working properly, though to be fair it also didn't appear to work in 0.7.1.1 either (at least for resize).
Will get some more attention soon.
