Changing Rotating Door To Sliding Door?

Hi all. I am working on creating a set of doors using the Multi User Lockable Door script, found at : /54/22/24116/1.html .

I have been experimenting and testing for hours, trying to make it into a sliding door instead, with no luck. Can anyone help me out?

set a local offset, apply the LOCAL rotation of the prim to it without modifying it, and then reverse that offset. when you go to apply it again, it'll be reversed and go back where it was... ALWAYS use local rotation to do this, and you'll never have to track changes in the global rotation.

example

vector gPosSlide = < 1.0, 0.0, 0.0 >; //-- the offset amount to move

default{
  touch_start( integer vIntNull ){
    llSetPos( llGetLocalPos() + gPosSlide * llGetLocalRot() );
    gPosSlide = -gPosSlide;
    //-- or replace the previous 2 lines with...
//    llSetPos( llGetLocalPos() + (gPosSlide = -gPosSlide) * llGetLocalRot() );
  }
}
