Weird physics?

I have not done a lot of work that relies on the physics options. But as I am trying something, I am seeing what I think is weird behavior.

I have written a script such that on touch, an object becomes physical and is supposed to move a specified distance. Upon reaching that target, it should send out a message which causes another prim to move.

Here is what happens. I turn off all rotations, set physics, make the object hover slightly, then llMoveToTarget. I also set llTarget to that same point. When I touch the prim, it moves partway then stops. If I rt-click to edit the prim, then close the edit window, *then* it moves the rest of the distance, hits the target, and sends info to the other prim.

Is this the expected behavior? Am I doing something wrong? Is there a way to overcome this?

The object does not have to be physical, but I need to be able to control the speed and want the movement to look smooth. Any other ideas would be welcome.

Thanks,
Baron

Running out of energy? How big is the prim? How far is it moving?

The prim is a standard plywood cube, moving it 5m.

well llMoveToTarget slows as it nears it's destination. i'm working on a "patrol" script and i read somewhere about the vector you feed to llMoveToTarget should be a little bit further than the vector fed to llTarget so that it keeps up the speed (this was mention on a thread involving a cart on a track i believe). i guess if it was notecard configured it would be easy enough, but i'm not sure how you would do it if you were to create a list within the script on the fly

Yepyep.

Beware of http://jira.secondlife.com/browse/SVC-2441 when doing that, though. If you're targetting a lower height and you're moving slowly, you can miss your waypoint. I think the problem is that they apply gravity incorrectly in some cases which causes objects moving downwards to move in sortofa hockey-stick path instead of a straight line.

You can (should!!!) also do a vote for http://jira.secondlife.com/browse/SVC-1479, which asks for a llMoveToTarget-like function but with more damping controls.
