Get the dimensions of a new object dragged into a prim's inventory?

[Domitan Redenblack]

If someone Control-drags a new object into a prim, what is the best way to get the dimensions of the new object?

rezz it - functions getting informations about an object only work when it's rezzeed - apart from the llGetInventory* functions

[Domitan Redenblack]

Thanks. Could you point me at the functions to get the dimensions after I rezz it?

llGetScale() only works on the current prim, not the one I rezzed, etc

[Darkie Minotaur]

Hmmm- now coming to think of it, the only way to get something size related from outside an object would be llGetBoundingBox() - but I may be wrong here

llGetBoundingBox works only on physics prims .

To add ,  for linksets , it will give the size of the linkset , not the size of the root prim

[Blob Megadon]

That is not true, llGetBoundingBox works on all kinds of objects: physical, static or even phantom. Only attachments will not return their bounding box, instead, the bounding box of their wearer is returned.

It will return a list with two opposite corners [vector min, vector max] of the bounding box which contains the entire linkset. This bounding box is relative to the root prim.

If you are just dealing with one single, simple (thus not twisted, sliced, sheared etc.) prim, you can use it to get a result equivalent to llGetScale():

// id is the key of the objectlist bb = llGetBoundingBox(id);vector min = llList2Vector(bb, 0);vector max = llList2Vector(bb, 1);vector scale = max - min;

You could combine this with llRezObject and the object_rez event to find out the scale of inventory items.

Thanks, Darkie and Blob - just the ticket! :matte-motes-big-grin-wink:
