Linden Lab Issue ID: DEV-13062


 Description  « Hide
While hovering, hold forward, back, left, right, rotate left or rotate right, or select an object that would make you turn towards it. The simulator slowly moves you down. I tried to counter it with an upwards force but it seems unreliable.

Moreover, it looks like a vertical movelock was applied in 1.22.2 to fix the 'sink when hovering and not moving' part; as a consequence, calls to llApplyImpulse on the z axis fail most of the time if the value is lower than 10 or so. This is a change of behaviour from havok1. Attachments that move an avatar just slightly are not working.

Description Start flying, stop moving (to hover).
No problem if you stand still, but if you rotate the camera (left or right keys), the simulator will start to slowly move you down.

Comment [ Maybe I'm wrong somewhere in my coding, but I noticed that llApplyImpulse has no effect on attachments while flying, no matter the buoyancy. Maybe it's related to this bug? ]

Start flying, stop moving (to hover).
The simulator slowly moves you down. llGetVel() doesn't report any z speed, but you need an upwards force of about 0.022488 m/s to counter this.

Hold rotate left or rotate right. This time llGetVel() reports a negative z speed. I tried to counter it with an upwards force but it seems unreliable.

Press forward. llGetVel() reports a negative z speed that slowly increases until it reaches 0. I tried to counter it with an upwards IMPULSE but it seems unreliable.
