texture anim - scroll once and stop

I'm trying to do the following animation...

I have a texture that is half white (on the left) and half black (on the right). I have a sphere with the following texture params:

Horiz repeats: .5
Vert repeats: 1
Rotation: 0
Horiz offset: -.25
Vert offset: 0

This gives me a white sphere.

Now I want the texture anim to scroll the black onto the sphere and then scroll it back off in the same direction. *NOT* ping-pong. I do not want the scrolling to change direction and double back to start. I want the black to scroll on and keep going so the sphere goes back to being white. And then I want the anim to stop.

Could someone please tell me the incantation to make this happen? What params do I need to pass llSetTextureAnim?

Thank you!

Why is it that as soon as I ask a question the next thing I try works? I should ask the question first

This does the trick:

llSetTextureAnim(ANIM_ON | SMOOTH, ALL_SIDES, 2, 1, 0, 3, .5);

The next question is, why can this only be done once? If I do the same anim again nothing happens. I have to do this...

llSetTextureAnim( FALSE, ALL_SIDES, 1, 1, 1, 1, 0.); // this turns off anim

before I can do another animation.

I think if you want it to stop rather than keep going, your best bet might be to create another texture (white, black, white). Otherwise you're probably looking for a an animation with the SMOOTH flag, but without ROTATE and SCALE.

texture animation is a prim property.

Thus, if you assign the *same* values for the animation then you will not see a change at all as for the prim itself, nothing changes.

Therefore you will either have to slightly vary the settings or "stop" the animation before starting the next one.
