About this script:
Drop this script into the prim you want to use as a curtain etc. The script will change the length of the prim on one or more axes. Use sliced or path-cut prims to keep an edge stationary, e.g. in a blind. For a Mesh prim, arrange for the pivot point to be on one edge.
You can use these scripts with any prim type.
// Prim Resizer (shrink/expand) by Omei Qunhua
// e.g. Roll a blind from the top. (use a prim with slice end = 50%)
// Note: This script can rescale a prim on any or all axes
// Define the large and small sizes of the prim here:-
// (if the prim is sliced or path cut, it will appear to be half size on the affected dimension)
vector gScaleLarge = <0.1, 3.0, 6.0>;
vector gScaleSmall = <0.1, 3.0, 1.2>;
integer gSteps = 20; // Number of steps in the shrink/expand process
float gSwitch = 1.0; // Action on first touch. +1.0 = shrink, -1.0 = expand

vector wscale = llGetScale();
gSwitch *= -1; // Switch between stretch and contract
integer i;
for ( ; i < gSteps; ++i )
{
// It is more lag-friendly to incorporate a sleep per step
// Rather than greatly increasing the number of steps
llSleep(0.1);
llSetScale(wscale + ScaleStep * (float) i * gSwitch);
