I'm trying to make a blanket retractable, but it doesn't retract the proper way. A side of the blanket moves to the other side instead of the top moving to the bottom, if that makes sense. I don't know much about scripting, so I'm not sure what I should be changing (or if there's anything I can change) in the code to fix this. Here's the script I'm using: //When touched the prim is retracted towards one end and when touched again stretched back out.
//
//Prim moves/changes size along the local coordinate specified in the offset vector below.
//
//To change the overall size, edit the prim when stretched out and reset the script when done.
//
//The script works both in unlinked and linked prims.

float hi_end_fixed = TRUE; //Which end of the prim should remain in place when size changes?
//The one with the higher (local) coordinate?

default {
state_entry() {
offset *= ((1.0 - min) / ns) * (offset * llGetScale());
hi_end_fixed -= 0.5;
}
touch_start(integer detected) {
integer i;

PRIM_POSITION, llGetLocalPos() + ((hi_end_fixed * offset) * llGetLocalRot())]);
