Smooth Sliding Door

Smooth Sliding Door Script

Introduction

It really annoys me that there are so many bad looking doors out there that jerk around. While you can use llSetPos for a sliding door you have no control at what speed it moves. This sliding door script i created because i wanted to time my sliding door movements with the door sounds i had. It uses llMoveToTarget to move the door, with the door temporally turning phantom as it moves.

In laggy sims it will behave a little bit funky .. the door sometimes seeming to zoom off to the side before popping into the correct final position as the door becomes a physical object. However, even with that defect it still looks much better IMHO
