Where looking on the new docs site, but i cannot find a command to get the position your avatar is. i would call it MyAvatar.position. It usefull to read the coordinates where your avatar is staying.
Is that command not implemented or just not on the docs site ?
on the wiki only found this line Vec3 MyAvatar.position so the command is available put need to be addded on the new docs site (like so many others 
So sorry for asking.
The script currentAPI.js is useful: it lists pretty much all of the current JavaScript API.
Note: MyAvatar.position can not be relied on to give the correct position every time . Specifically, when the avi is in motion, it will often report the last frame’s position.
The effect of this can be seen here: https://www.youtube.com/watch?v=iviIjFgyKGY
The bug is caused by Interface / JS thread timing issues, and according to the devs may not be possible to fix…
Sorry to be the guy with the bad news!
I use in my places.js:
var pos2 = {x:1057.7, y:162.8, z:965.4, rx: 0.0,ry:0.966, rz: 0.0,w:0.0, p:“pose1” } ;
var posi={ x: pos2.x,y: pos2.y,z: pos2.z};
var rosi={ x: pos2.rx,y: pos2.ry,z: pos2.rz};
MyAvatar.position=posi;
MyAvatar.orientation=rosi;
It dos work well. I use it for teleporting to different places at my island, where I also active the pose, which I want for this place.
The function is supposed to be print out “MyAvatar goToLocation - moving to” and used mainly with location and rotation with the vec3, bool, quat). Setting the position directly is also possible since Javascript doesnt really have private/public methods.
If it doesnt print this out it means the script interface might have a bug (it has happened before with getting bone velocities, so it can also happen with the setters)
