A chair rezzes odly

Hello good people of the building forum,

The story in a nutshell (full version will be brought out on DVD, lasting 1.5 hours, but I try to pin down the essentials here): I built a chair, and every time I rez it from my inventory, it rezzes several meters up in the air. I bring it down and save my new, earthbound version - but when I rez that new version it, too, rezzes up in the air, just like the old one. Conundrum! Anybody know what to do about this?

Thanks,
Xylo

Perhaps the chair has an invisible component below it. Check "view invisible" under the view menu.

Or you could run one of the scripts from this post:

Dank je wel, ed! Ik ga dit gauw proberen.

Oy, that didnt work....I don't seem to have an option 'View Invisible'. Unless you mean 'Highlight Transparent'? I'm green enough not to know whether invisible and transparent are the same, in SL.

If the chair uses a cut prim on the lower surface, it will rez as if it was sitting on the whole prim. For example, if I make a park bench, and use a half of a circle for the legs, and that circle is 1 meter in diameter, the bench will rez 0.5 M too high.

The solution is to add a script to the chair that adjusts the height after it rezzes. Here is a simple script for that:

// adjust this height 
float adjustHeight = -0.5; // how much the position should be adjusted when the object is rezzed. (m) -

default 
{ 
   on_rez(integer x) { 
      vector v = llGetPos (); 
      v.z = v.z + adjustHeight; 
      llSetPos(v); 
      } 
} 

Just add this script to the item, and change the "adjustHeight" variable as needed. As shown above, it moves the item down 1/2 meter.

Thank you, Ceera. In your kindness, you and ed are causing me untold hours of work. Because I'm realizing that I have to start learning LSL. I suppose one can get by without it, but seeing your scripts, I want to be able to make my own. And just when I thought I'd go out and get a tan in the wonderful winter weather* we have in my country...
