set movement scripting

I am fairly new to the sl scripting world and am trying to create the following.

pretty much, what I want to do is make a veichile that starts at a specific location, and moves to another location. I only want it to go to those two locations, back and forth, no where else. Yet I can't seem to find the right type of code, I have looked at the llSetPos, but I can't control the speed of it, and it only moves 10 meters at a time, and is sort of jumpy.

Any suggestions would be more than welcomed.


Thanks

Try llMoveToTarget

That one only goes up and down, not sideways and you could strip the rez function. It will mainly give you one more example to look at to help making your own.

Look around for warp pos...it is a programming trick to get around the 10m at a time and jerkiness problem. (Not me...the jumpiness you mention.)
