Description

« Hide

If I fall onto the top of another avatar's head, I will become stuck in the falling animation and unable to move my avatar. Entering flight mode returns control of my avatar. However, if I fly up and fall back down onto the head of the other avatar again, I will become stuck in place with falling animation and unable to move again. This process can be repeated an unlimited number of times.

I have used both scripted and unscripted (manual control) methods of positioning my avatar over the head of another avatar. I have also tested this with an avatar wearing no objects at all.

I am not sure when this bug first appeared, but it is recent - within the past few weeks.

Setting this issue to Major since it affects one of my products, MystiTool.

Please provide your computer environment (computer specs). Most likely you can't "land" because there is an object (the person) below you. This happens regularly when I TP to a location and people have not moved from the landing point. the next time it happens, try moving to the left or right to a place where no one is standing and you should be able to land normally.

My original description clearly states "if I fly up and fall back down onto the head of the other avatar again, I will become stuck in place with falling animation and unable to move". There are no obstructions between my falling avatar and the avatar's head below me.

I would be very happy to demonstrate the issue inworld. I will be inworld for the next few hours.

Though I feel my computer's specifications are irrelevant, I have been proven wrong several times.

Alexa, ever since Havok4 was released avies can no longer land or jump on other avie's heads without freezing or going into a leg twitch. My group used to pride itself on jumping on peoples heads in mouselook...now when attempting to jump on another avie's heads yer legs fold into a weird twitching position or you freeze in a landing anim and can't move.

Here's an example of precision jumping in old Havok1: http://youtube.com/watch?v=fY5JQ8JJVyg That's what we used to do jumping on avie's heads...we can't do that anymore without freezing or our legs folding.

So this is a Havok4 physics bug. When an avie is standing on another avie's head the avie on top either twitches or freezes.

Switched to 1.20.0 Server Physics cuz this bug didn't manifest til Havok4 was released.

<joke>This should be showstopper as the ancient art of !stand is severely impacted</joke>

This seems related to what Sidewinder calls "BumpLag" where when you hit an object at just the right angle you flip into the falling animation and stay that way until you fly or the sim finally fixes you.

It is seen when hugging and stops when the other avatar finally moves (No movement when you come down exactly on top of an avatars head and also when walking up stairs.
