Need Help with Simple Rotation

Ok I know this must be out there somewhere and I am no script writer so thought I would ask for some help.

I make clothing and would like to display my prim flexi skirts in my store. I would like to be able to put a script in the root prim to make the skirt rotate to the left 90 degrees and than rotate back to original, rotate than 90 degrees to the right and than back to the original, than perhaps pause for 10 seconds and repeat.

This is to show off the movement of the flexi prim skirt or attachment.

Any help would be greatly appreciated.

Thanks so Much
Charity

Rough outline...

Off top of head, no doubt full of syntax errors...

CODE
 // yeah, like that will ever work

rotation rot;

default {
   state_enter() {
        rot = llGetRot();
        llSetTimerEvent(10);                 //every ten seconds
   }

   timer() {
       vector newrot = llRot2Euler(rot);
       newrot.z += 90*DEG_TO_RAD;  // 90 to the left
       llSetRot( llEuler2Rot( newrot );
       llSleep(1);                                // pause 1 second
       llSetRot( rot );                          // rotate back
   }
}

Put this in a cylinder.  Put the skirt on the cylinder like a mannequin.  Either make the cylinder invisible, or decorate it somehow.  If you have a real mannequin, you could prolly use that.

I think it'd be better to do it via llTargetOmega. Less lag and a lot smoother animation.

llLootAt() or llRotLookAt() could also work. They would give you roughly the same kind of control llTargetOmega() would for the speed of rotation and also let you control the start and end positions instead of guessing and having it be different on each viewer.

I normally stick an llSetRot after the llTargetOmega to correct any problems with the rotation being slightly beyond it's intended spot. Sans bad lag, it usually displays the rotation quite accurately. I haven't tried llLookAt or llRotLookAt yet. Are there any pros and cons between the two solutions?

Yes a syntax error , I would be happy to pay someone to make a script for this.
and I have a manaquin top to link to the skirt that can be the root prim.

Thanks Again

   }

The problem was that you didn't put the open {'s on their own line. There were also a couple typos that I fixed. The above should compile now. 

Make sure that the cylinder that Lee suggested linking in is the root prim..

Make sure you have this at the very top of the script:

rotation rot;

It's in my post above but it's on the same line as the ever-so-useful
CODE
 tag..

ok so now I have my skirt going to the left
12-01-2008 11:14
So how would I change this script to make it go left first than back to center than to the right and back to center? pause 10 seconds and repeat.

Thanks Charity

Maybe something like this would work...

CODE

float direction = 1;
rotation rot;

default
{
	state_entry()
	{
		rot = llGetRot();
		llSetTimerEvent(10.0); //every ten seconds
	}

	timer()
	{
		vector newrot = llRot2Euler(rot);
		newrot.z += direction * 90.0 * DEG_TO_RAD;
		llSetRot( llEuler2Rot( newrot ));
		llSleep(1.0); // pause 1 second
		llSetRot( rot ); // rotate back

		direction *= -1;
	}
}

edit: if hit the Quote button, the formatting will reappear. Good trick to do when you're copying/pasting scripts from the forums.

This is called "changing the requirements" and is not allowed.

What, never heard of feature creep? ;-)

Something like this should work (not yet compiled; MAY need minor syntax fixes):

CODE

float FRAME_DURATION = 1.0;
list FRAME_ROTS;
integer N_FRAMES;

rotation initialRot;

integer nextFrame = 0;

default
{
   state_entry()
   {
      FRAME_ROTS =
         [ llAxisAngle2Rot(<0.0, 0.0, 1.0>, -PI_BY_TWO),
           ZERO_ROTATION,
           llAxisAngle2Rot(<0.0, 0.0, 1.0>, PI_BY_TWO),
           ZERO_ROTATION ];
      N_FRAMES = llGetListLength(FRAME_ROTS);

      initialRot = llGetRot();

      llSetTimerEvent(FRAME_DURATION);
   }

   timer()
   {
      rotation frameRot = llList2Rot(FRAME_ROTS, nextFrame);
      nextFrame = (nextFrame+1)%N_FRAMES;

      // Reverse order of multiplication to rotate about GLOBAL axis
      llSetRot(frameRot*initialRot);
   }
}
