Fix for MyAvatar sometimes hovering off the ground after foot tracking was enabled. MyAvatar's body is now recentered when foot-tracking starts or ends (in MyAvatar::update).
Repro:
- Start without foot tracking, 'Allow my avatar to stand: Always'.
- Crouch, and wait a few seconds for the avatar to pop back to the standing position.
- Slowly stand straight so that the avatar raises off the ground without recentering (PS: is this a bug?). If it recenters, retry from previous step.
- Calibrate foot tracking. Previously the avatar would remain hovering off the ground until MyAvatar::centerBody was called.
Fix for MyAvatar popping to a standing position if the left foot lost tracking. The recentering now takes into account if either of the feet are tracked.
Repro:
- Enable foot tracking (and ideally hips tracking).
- Sit on the floor.
- Cover the left foot sensor so it loses tracking. Previously the avatar and viewpoint would pop to a standing position.
Optimisation: MyAvatar::update now stores bools indicating which body parts are tracked (_isBodyPartTracked). This avoid unnecessary computations that came from using getControllerPoseInAvatarFrame to convert controller::Pose from sensor space to world space and then to avatar space, only to check if the pose was valid.
Previously, if the avatar scale wasn't 1, the body and viewpoint would given the wrong vertical position in some situations, eg: getting up from click-to-sit; changing the 'Allow my avatar to stand' setting.
The avatar scale was being taken into account where it shouldn't have in MyAvatar::deriveBodyFromHMDSensor.
The bug started in 8b839fe71b ("VR fixes for different user heights and avatar scales".
Repro:
1. Set 'Allow my avatar to stand: Always'
2. Reduce the avatar scale to the minumum.
3. Set 'Allow my avatar to stand: When I stand'
4. Previously, the viewpoint would suddenly be below the floor.
- The user's real-world height is now taken into account in MyAvatar::deriveBodyFromHMDSensor. Therefore, for any user height, the floor stays correctly positioned in all modes of 'Allow my avatar to stand'.
- Whenever the user's real-world height is changed, centerBodyInternal is now called to position the body accordingly. The floor therefore stays correctly positioned in all modes of 'Allow my avatar to stand'. (MyAvatar::setUserHeight)
- Fix for walk speeds in VR being too fast at large avatar scale and too slow at small avatar scale. The action motor velocity was being scaled once too many by the sensor-to-world scale. The bug existed before this branch. (MyAvatar::scaleMotorSpeed)
Moved the body of the function to a private internal method (centerBodyInternal), which takes the parameter instead.
Previously, when leaving 'away' state, the 'Away' overlay would stay on screen because of the bug.
The bug started in "VR fixes for: couldn't sit on the floor, wrong walk directions." (2179c153de).
- Divided the option "Avatar leaning behavior" into two options that work more usefully: "Allow my avatar to stand" and "Allow my avatar to lean" (PreferencesDialog.cpp). Made the necessary fixes so that the avatar can be set to stand only when the user is standing (more details below).
- The logic controlling the direction of MyAvatar's action motor is now centralised in calculateScaledDirection (was previously split between there and updateMotors). calculateScaledDirection now returns a velocity in world space.
- CharacterController::FollowHelper now uses separate follow timers for rotation, horizontal and vertical (previously followed all three based on the longest of their follow times). Where appropriate, FollowHelper can now snap immediately to the desired rotation/horizontal/vertical independently (see FOLLOW_TIME_IMMEDIATE_SNAP).
- FollowHelper::FollowType has therefore moved to CharacterController::FollowType.
- MyAvatar::FollowHelper::postPhysicsUpdate: If MyAvatar is not allowed to stand when the user is sitting, this now avoids recentring the body based on the head height.
- Removed Q_PROPERTY(MyAvatar::SitStandModelType, as the sitting/standing/leaning model uses different enums now (see setAllowAvatarStandingPreference, setAllowAvatarLeaningPreference).
- Removed Q_PROPERTY(bool isSitStandStateLocked which is no longer used, because we now always track the user's real-world sit/stand state, regardless of what we're doing with it.
- MyAvatar::FollowHelper::shouldActivateHorizontal: If MyAvatar is not allowed to lean, this now returns true to recentre the footing if the head is outside the base of support.
- MyAvatar::FollowHelper::shouldActivateHorizontalCG: If MyAvatar is not allowed to lean, this now always returns true to recentre the footing. Rearranged to avoid computing values that weren't used depending on the conditions. Resolved some duplicated code.
- MyAvatar::setUserRecenterModel previously set HMDLeanRecenterEnabled based on the chosen mode, but it got reset when getting out of a sit. Now HMDLeanRecenterEnabled is only controlled by the scripts.
- Added Rig::getUnscaledHipsHeight (like getUnscaledEyeHeight). Refactored a little to avoid duplicated code. Added DEFAULT_AVATAR_HIPS_HEIGHT which is the value that Rig::getUnscaledHipsHeight returns when using the default avatar.
- Fix for recentring not behaving as requested by the user after getting up from click-to-sit (always behaving like 'Auto') : MyAvatar::endSit now passes false to centerBody for 'forceFollowYPos'.
- Fix for incorrect vertical position of the avatar and viewpoint after changing lean recentre mode while not standing in the real world: MyAvatar::setAllowAvatarStandingPreference now calls centerBody with false for 'forceFollowYPos'.
- computeHipsInSensorFrame: The code now matches the comments in that it only skips the dampening of the hips rotation if the centre-of-gravity model is being used.
The android specific optimized IK animation graph was out of date, it was referencing
animations that have been deleted, hence the t-pose. This PR updates and renames the
android/optimized ik animation graph to the latest.
If MyAvatar::setSkeletonModelURL() is called with the same url that has already been loaded the
SkeletonModel::skeletonLoaded signal will not be triggered. In this case the MyAvatar local variable
MyAvatar::_skeletonModelLoaded will be set to false and never re-set to true. This, in turn,
caused MyAvatar::updateHeadLookAt() to skip setting the proper blend values that would turn the head.
Rather then try to make MyAvatar::_skeletonModelLoaded handle all the possible edge cases. It has
been removed. All conditionals that used to use it have been replased with _skeletonModel->isLoaded().
* Moved hasScriptedBlendshapes, hasProceduralBlinkFaceMovement, hasProceduralEyeFaceMovement, hasAudioEnabledFaceMovement to AvatarData
so they are accessable via agent scripts.
* Marked setForceFaceTrackerConnected as depricated.
* Updated jsdoc comments
