A very simple door

Build a door as following:

cube, .2x4.25x3.33, (cut: .375-.875) apply a texture of your choice (maybe a real door?)
put following script inside:

// improved door script by Ezhar Fairlight
// features: automatic closing, workaround for rotating out of position,
// doesn't mess up when moved, adjustable direction (inwards/outwards)
// updated for SL 1.1 damped rotations, small bugfix

// ********** USER SETTINGS HERE **********
float       TIMER_CLOSE = 5.0;      // automatically close the door after this many seconds,
                                 // set to 0 to disable

integer     DIRECTION   = -1;       // direction door opens in. Either 1 (outwards) or -1 (inwards);
// ********** END OF USER SETTINGS **********



integer     DOOR_OPEN   = 1;
integer     DOOR_CLOSE  = 2;

vector      mypos;      // door position (objects move a tiny amount
                     // away from their position each time they are rotated,
                     // thus we need to workaround this by resetting
                     // the position after rotating)
                 
door(integer what) {
 rotation    rot;
 rotation    delta;

 llSetTimerEvent(0); // kill any running timers

 if ( what == DOOR_OPEN ) {
     //llTriggerSound("Door open", 0.8);

     rot = llGetRot();
     delta = llEuler2Rot(<0,>);
     rot = delta * rot;                  // rotate by -45 degree
     llSetRot(rot);
 
 } else if ( what == DOOR_CLOSE) {
     rot = llGetRot();
     delta = llEuler2Rot(<0,>);    // rotate by 45 degree
     rot = delta * rot;
     llSetRot(rot);

     //llTriggerSound("Door close", 0.8);
 }
}
 

default {   // is closed
 on_rez(integer start_param) { // reset, so we store the new position
     llResetScript();
 }

 state_entry() {
     mypos = llGetPos();     // remember where we're supposed to be
 }

 touch_start(integer total_number) {
     door(DOOR_OPEN);
 
     state is_open;
 }

 moving_end() {  // done moving me around, store new position
     mypos = llGetPos();
 }
}

state is_open {
 state_entry() {
     llSetTimerEvent(TIMER_CLOSE);
 }

 touch_start(integer num) {
     door(DOOR_CLOSE);
 
     llSetPos(mypos);        // workaround for tiny movements during rotation
 
     state default;
 }

 timer() { // it's time to close the door
     door(DOOR_CLOSE);
 
     llSetPos(mypos);        // workaround for tiny movements during rotation
 
     state default;
 }

 moving_start() { // close door when door is being moved
     door(DOOR_CLOSE);
 
     state default;
 }
}

The door should be working
