Easy Sit Target Positioner has been updated on XStreet:
http://xstreetsl.com/modules.php?name=Marketplace&file=item&ItemID=318690
The new version doesn't have a 'touch' handler when in normal furniture mode. Also, it uses a menu to set the sit target or change to furniture mode. (Just to set the target using the helper, not to adjust offset/rotation by menu.)
Why? I was enjoying a very nice build where someone had obviously used ESTP for prims one could sit on. It was an interactive build, and some things were clickable. But the places to sit showed the hand cursor, implying clickable. Of course, in furniture mode, only owner can click, and only to do a long click to set back to sit-target-setting mode.
So I changed it. Now, if you want to go back to sit target setting mode, you just reset the script.
Check it out and let me know what you think, about functionality or coding.
Thanks!
