the world and teleporting

Hi, this is my first post, I'm not really a posting kind of person on forums..usually just a reader, but I've got a problem/question that I can't seem to find the answer to.

When you use //teleport to move somewhere the z coord is optional and I've noticed it always sets me right on the ground. I've also noticed that when you use //worlddebug it tells you all of the z coords that exists at your location where the server thinks there is something solid. My questions is, is there a way to teleport or spawn something to a Z location other than where the server thinks there is solid groud? Everytime i try it always puts me at the same level.

Also another side question when you use //worlddebug it gives you the x,y coorde an then says index: (#,#), what is that index? Just curios :smilie3:

Well, partly an answer for you.

The server simply says ok, the client want to go to X and Y - it then picks the highest Y point that it knows here.
If the server doesnt think theres solid ground you would end up below that most likely, same with mobs.

One way to think of the teleport function without Y is "Lets spawn him at X, Y and 100000 as Z and let him drop to the ground" :-)
