How to extend/contract object size/dimensions?

Hi,

What's the best way to script the modification of an objects dimensions?

For example a vertical post with a light on the top, and I want to have the height of the post slowly getting smaller, then larger, then smaller etc. I'm not sure that making it a vechicle would help. Would really like to be able to say OBJECT.WIDTH=xxx, OBJECT.HEIGHT=xxx

Tks

llSetPrimitiveParams()

You'll need to build an incremental loop into your script so the prim transitions more smoothly.

Yea...loop it with a very small "step". It's gonna be "jumpy" anyway...but if you keep the step small it'll be nice enough.

could use a for statement

integer x;
integer max =5;
default
state_entry
{
   for (x = 0; x < max; x++) //do stuff 5 times from 0 to 4
      {
        (vector) size = <1,1,1>;
        set prim prams stuff
        size += <0.5,0.5,0.5>;
      }
}

dont quote me on that tho heh

Tks - I take it anything LINKED to top of the prim will go up as well no doubt (e.g. the light on the top of the post)

Ooh, that's going to pose a problem. In order for the linked primitives to move along with any other you need to adjust their positions when the resizing prim resizes. Due to our inability to affect two primitive's properties at the exact same time, the movement will appear jerky at best, horribly miscalibrated and random at worst.

i agree but it doesnt have to be as horrid as it sounds... eventho I R teh SUXOR at math, but it seems like sin and cosin could be used here, get the start positions and end ones along with size and let lsl handle the curve

Its not as easy as you make it out to be - try getting two things to move in sync (without linking them) in something as simple as a straight line. One lags behind the other randomly.

yep but i was trying to bing some form of hope to something that at best is gonna be awkward hehe

I was thinking the pole and light on top could be linked - the llSetPrimitiveParams would need to be applied to one of the linked items if this is possible - if it is hopefully the linked objects would move in coordination no?

Yes, linked objects will move together. However, they will not SCALE together. So, if you want a light pole that grows taller (but not thicker), then one script should do the trick. Simply make a 10m tall pole, and have it mostly buried until it needs to rise.
