Script resetting issue

have a few vehicles and have had no issues with the scripts resetting upon rezzing them. I am builing my first vehicle and the scripts do not seem to reset completely. In fact, I can take out the sound files, reset the script and the sound files still play and I cannot get other sound files to play in the vehicle. Any ideas?

Sound is a prim property, like hovertext. In your onrez event, you may want to use:

llStopSound();

Just for kicksies, here's a scrubber for all the prim properties:

default
{
state_entry()
{
llSetSitText( "" );
llSetTouchText( "" );
llParticleSystem( [ ] );
llSetText( "", ZERO_VECTOR, 1.0 );
llTargetOmega( ZERO_VECTOR, 0, 0 );
llSetCameraAtOffset( ZERO_VECTOR );
llSetCameraEyeOffset( ZERO_VECTOR );
llSitTarget( ZERO_VECTOR, ZERO_ROTATION );
llSetTextureAnim( FALSE , ALL_SIDES, 1, 1, 0, 0, 0.0 );
llStopSound();
llOwnerSay("This Prim is Clean... ");
llRemoveInventory( llGetScriptName() ); // vanish without a trace...
}
}
CODE

What exactly does it do?

It removes any properties scripts might have added to a prim or object, and then deletes itself.

Is sound really a prim property? I wasn't aware of that. But, that does jive with the OP's post!

Lear's right. Prim properties are attributes that stick around in the prim even after the script that activated them is deleted (like particles and hovertext). They keep going until another LSL command is issued that deactivates them explicitly.

The scrubber script I gave you deactivates most of the prim properties that LSL can control, and then deletes itself. I use it as a quick reference if I forget the syntax to deactive a specific prim property; I don't usually use the whole thing.
.

Cool. Thank-you, I'll give it a try.

I do have the llStopSound(); in there but the sound stops only when exiting the vehicle.

... and llSetTextureAnim() is REALLY sticky. It will persist even if you take it into your inventory and re-rez it. Hovertext and such will go away, but nothing short of calling a null llSetTextureAnim will stop an animated texture

Good point that texture animation is a property that's missing from the script above.

In my experience, however, prim/object properties such as hovertext, sit targets, and particle systems do *not* go away when you take an object into your inventory and re-rez it. Many's the time I've used a set-text script that deletes itself immediately, and I have a lot of experience with sit targets.

However, shift-dragging an object to copy it will lose most or all of these object properties. Whether that applies to all of them, I couldn't say. It's easily tested.

ok thanks.
