How can i make a prim extend when it is touched/clicked?

What I mean by this is say for example, in the stargate series, the big whoosh thing comes 'out' from the gate and then retracts.

Is it possible to make a prim do this kind of action when it is touched/clicked.

 

Thanks

Yes.  Take at look at llSetPrimitiveParams.  That and a timer will make a prim do that. 

I wonder if it wouldn't be better to use a particle system instead or a combination, since when the stargate is activated it is more like a cloud reverse vortex that comes out.

I have no experience of scripting or particle systems, so I don't know really where to start.

The place to start is the Particle Laboratory at http://maps.secondlife.com/secondlife/Teal/200/61/22 .  That's how most of us started learning how to handle particles.  Spend an afternoon playing with all of the demos and then hanging around in their sandbox.  There's a nice selection of sample effects that you can experiment with.

Rolig told you where to go to learn how to do particle scripts which aren't hard at all.  They have a all purpose particle script for free that is already written and you can change the variables yourself to get what you want.  There is a tutor display there that explains what all the variables do. You can also pick up some free scripts for various things too.

To learn to script to extend the prim you can take classes in world at a number of places.  Search events for classes.  If you have some RL knowledge of programming or scripting you can probably teach yourself using the Wiki LSL Portal.  I did.  LSL is not difficult to learn if you have some background.

Both things are very handy to know if you are a builder.  It will save you a lot of L's over hiring scripters or buying commercial scripts.

If  you don't want to learn, then post your needs in the Wanted Subforum under Commerce to hire someone who will write a script for you for a fee.
