Instantiate as child of a to-be-instantiated list item

Question

Hey =)

I have a bit of trouble transfering what I read in the previously asked questions about this topic in this discussion board to my own problem and would appreciate a bit of help.

I have a few lines of code that look like this:

 for (int i = 0 ; i < 3 ; i++)
 {
     kandidatenliste.Add (Instantiate(npcs.npc[i], KupplerinTransform));
     heiratskandidaten.Add (Instantiate(heiratskandidatPrefab, XXX ));
     heiratskandidaten[i].name = "Kandidat: " +npcs.npc[i].vorname +" "+ npcs.npc[i].nachname;
 }

"XXX" describes where my thought process takes a break. I want to instantiate "heiratskandidaten" as a child of each entry of "kandidatenliste". Right now, it is being instantiated right underneath it. alt text

I have found a couple questions which sounded the same, but I have not found a question where the to-be-instantiated object needs to be the child of a to-be-instantiated list item...

Help would be appreciated :)

Shortest option (requires System.Linq):

heiratskandidaten.Add (Instantiate(heiratskandidatPrefab, kandidatenliste.Last() ));

The same without Linq:

heiratskandidaten.Add (Instantiate(heiratskandidatPrefab, kandidatenliste[kandidatenliste.Count - 1] ));

And a version that is more readable imo but a bit longer:

var kandidat = Instantiate(npcs.npc[i], KupplerinTransform);
var heiratskandidat = Instantiate(heiratskandidatPrefab, kandidat );
kandidatenliste.Add (kandidat);
heiratskandidaten.Add (heiratskandidat);

Thank you so much :D! I've tried your solutions, but none seemed to work - but they brought me to the right solution! I hadn't understood that a list entry could be its own Transform in my hirarchy =D Based on that, I added a temporary transform for the last entry in the list and now, it works like a charm :)!

 kandidatenliste.Add(Instantiate(npcs.npc[i], $$anonymous$$upplerinTransform));
             Transform tmpTransform = kandidatenliste[i].transform;
             heiratskandidaten.Add (Instantiate (heiratskandidatPrefab, tmpTransform));

Now, I wonder why "kandidatenliste.Last()" and "kandidatenliste[kandidatenliste.Count - 1]" didn't work... But I will leave that particular head-scratcher to tomorrow.

Thanks a ton, you've helped me a lot =)!

Hm, do your lists contain GameObjects or Transforms? Only a transform can be set as parent so that might be the reason.
