Why don't we stand still while on a moving platform???

I'm sure we all have seen this..

You're on an elevator, or any other platform of the sort... while it is moving (I have only been on elevators... I don't know if it also happens on horizontal movement) up or down, my avie starts moving like it's frantically running.
My guess is that the avies are programmed to run as they start "falling", and the physics engine doesn't seem to keep them on the ground at the same pace as the moving platform. I've seen it happen both on slowly moving and fast moving platforms.

Now, that past explanation might be good for the downward movement, but what happens with the upward movement? Why does he run up too? As I said, I have yet to try out some horizontal moving platform. Maybe I'll script one out to see...

Although it's not killing anyone, but in the order of making SL more lifelike, I'd like to see myself as a calm business man taking the elevator up towards my 50th floor office as I stand gracefully and with certain personality... rather than watch him jogg up for the 15 second long ride..

Anyone on my side here?

add them up and we have

2The 2difference 2between 2me 2and 2you = 0

2(The difference between me and you) = 0

The difference between me and you = 0/2

The difference between me and you = 0

I never thought we were so similar :eek:

Absolutely.

As a kid, I was fascinated by moving parts. To-wit: My parents gave me the birthday present of a lifetime by taking me on a tour of the local Coca-Cola Bottling facility. Mechanical arms and conveyor belts EVERYwhere...I thought I'd died and gone to Little Geek Heaven.

And, of course, I loved all elevators, and would find any excuse to ride and re-ride them. When I was 11, my grandmother (who knew me all too well) invited me to spend some time with her one summer in Atlanta. One day, she said, "Hop in the car" and I could see the Unmistakeable Grandmother Twinkle in her eye. She took me to downtown Hotlanta, and we walked in the front door of the Regency Hyatt House. She waited for me to pick my jaw up off the floor, and said, "Go play...I'll see you in an hour."

I want multiple sliding doors that can operate smoothly and impressively without having to do that step-stop-step thing that llSetPos() causes. I want perfect docking on every level. I want tubes that extend and retract smoothly into the floor and ceiling, like George and Judy Jetson had.

I want multiple induction-drive cars, figuring out how to stay out of one another's way in the same shaft. Ultimately, I want a horizontal/vertical elevator, like the one I've heard they're implementing somewhere in Tokyo. And I want a smooth ride. My inability to get those things has been my only real frustration in SL.

I think you've probably hit the nail on the head with the "elevator boogie" problem on non-physical lifts, but I'm sure there are vastly more experienced folks who can provide a more trustworthy asnwer. The (few) successful elevators I've seen offer the passengers a seat; apparently sit-scripting calms the motion calculator down.

My limited experiments with physical elevators have also been a bit disappointing; from what I can piece together from the forums, the current physics engine sometimes gets a little coarse in its calculation of collision bounding boxes. I haven't really been able to get things as close to one another as they need to be and have them work reliably. Or, it could just be that I really suck at building; always a popular theory among those who know me.

Anyway, I'm definitely on your side, and I'd love to see this get better.
