llSit on target

I am trying to create a basic sit ball that will (no matter the avatar hieght) make the person
stand at floor level.

This is a basic ball that people can use to align dancers with.

go to basic and some avatars feet go below the floor

I have it now where I rez a ball on the ground. I take the messurement of the avatar and devide by 2 that is my Z axis offset.

Now if I take a close to 6 foot avatar and make him stand, it works perfectly
but if I shrink my avatar down he dances much higher than a taller avatar.

I do do a llResetScript everytime a avatar stands up.

I am confused as to why the smaller avatar is higher.

Are you monitoring what height the ball finds for each person? Make sure that the height it finds is correct. I don't really know where the center of sitting is, but that might also be giving you trouble.

yes I monitor the height and the values do change which is wierd that I don't see the effect for it. One thing I was wondering is, if ocne a script is rezed and the first avatar stands on it would the sit on target update only once? it is perplexing but not a major problem.
