whatz the order of linking

i know that the object selected in the end is the root.
but i tried with three object say 1,2,3
when i touch 1 it becomes child of 2
then when i touch 2 it becomes child of 3 and since 1 is already its child this works fine
if i now unlink 3 i get back the parent child relation between 1 and 2

but when i touch 2 first it becomes child of 3
now when i touch 1 it becomes child of 3 but parent of 2, whyz that so ??

42.

Want to save yourself a lot of headaches? Name your prims, then you can find their link numbers at runtime with llGetLinkName.

that i already did, but i just want to understand the order of linking. neone plzzz.......

For LSL, if you link a new child, its prims are inserted into slot 2, and then older children are appended to the end. Your description with "touching" is a little confusing (are you using the editor, or some script?) but does that match what you are seeing?

This may help explain things: http://www.lslwiki.net/lslwiki/wakka.php?wakka=llCreateLink

i am using scripting for linking, no selection and then link, but touch then llcreatelink.
