Summary0008637: Events moving_start() and moving_end() don't work the same as in Second Life
DescriptionIn Second Life these events are triggered by any movement but in OpenSim they are not. I have tried moving physical objects and also using function llMoveToTarget and in no case do the events seem to fire.
Steps To ReproduceCreate a sphere, make it physical and add the simple test script below. Then move the ball by hand. In Second Life as soon as it starts and stops moving it will report this via the moving_start & moving_end events, however in OpenSim it doesn't trigger these events.

This was already discussed in past ( mantis 6519)
when the events were made operational only for KFM and MovetoTarget
already then it was known SL did it on more cases...
but never improved
now many scripts may have handlers only considering those cases, and some may misbehave on editing position
fun fun..

I did try with MoveToTarget in a 0.9.1 region and that didn't trigger the events.

I guess if it's a case of "that's how it is" at least the wiki at [^] needs updating to show this in the notes column...

acording to those old mantis it should work (?)
issue now is how ill defined that actually is, at sl seems just a position change when code is actually "looking", didn't test enter sim, but on rez does not trigger them now, position change on edit triggers both at edit release (at least right order)
also seems some needed filtering is up (we will need some, position can have "noise")

With this ill conditions definition don't see how this things can be used reliable on any script, even "there" (didn't even looked to attachments cases where wiki just says "something" needs to be done)
I still don't say its a case of "that's how it is" but sure not that c... we see there...

Here is a test script I tried out - very chatty in SL but nothing in OpenSim

        vector pos = llGetPos();
        llSetStatus(STATUS_PHYSICS, TRUE);
        // Little pause to allow server to make potentially large linked object physical.
        // Look for owner within 20 meters in 360 degree arc every 1 seconds.
        llSensorRepeat("", llGetOwner(), AGENT, 20.0, PI,1.0);
    sensor(integer total_number)
        // Get position of detected owner
        vector pos = llDetectedPos(0);
        // Offset back one meter in X and up one meter in Z based on world coordinates.
        vector offset =<-1,0,1>;
// offset = offset*llDetectedRot(0); //Adding this line will orient the follower relative to the owner's position.
