* Removed MyAvatar.reset() access from JavaScript
* Added HMD.centerUI() to JavaScript, which can be used to reset the 3D UI sphere around the current HMD orientation.
* Added MyAvatar.clearIKJOintLimitHistory() which can be used to reset any remembered IK joint limit history.
* Added MyAvatar.centerBody() which can be used to instantly re-orient the avatar's so that the hips and toes
are facing the same direction as the current HMD orientation.
away.js now uses the above new API's instead of MyAvatar.reset()
We could only partially fill the _scratchBuffer - .wav files may not
be exactly N frames long. Doh.
While at it, I needed to call finishLocalInjection() after local
injectors are done, and the access to the injector vector needs to
be locked, given that we do a QtDirectConnection with the networking
and thus the outputLocalInjectors is on a different thread.
The clicking was just 0-ing out the _scratchBuffer.
Before this fix, a hand vector was being tracked that was the difference between the avatar's hand in avatar space with the avatar's hand
in avatar space the previous frame. This hand vector was used to move the grabbed object position. However, when the body shifts, objects
in the avatar's space will change rapidly, this would cause this hand vector to be incorrect and cause the object to shoot off in the distance.
Now, we track this hand delta in sensor a.k.a. room space. This is immune to the shifts caused by body shifting.
When I "fixed" my or instead of and issue, I did it in the wrong
direction. But it looked right :) Now it is. Sigh. Long story
how it got there, but it seems good now.
The zone settings are still used, and still match the documentation where 0 = no attenuation and 1 = max attenuation. The default is now 0.5 which corresponds to -6dB per doubling of distance. This is the attenuation for a spherical wave in the free field.
Code a bit more readable. Sadly (and I guess it makes sense), a
enum class XXX is not a class, so you cannot have member functions
for it. I can imagine no way to have a vtable if you are really
representing it as a uint8_t or whatever. So, I put a stateHas
function in the AudioInjector instead. Definite improvement.
