If you saw that in an Etho's Lab video, he built an Endermen farm in the sky. The Endermen fall 42 or 43 blocks and that brings their health down to half a heart, so they can be one-hit killed. LP Episode 151 shows the process of building it and LP Episode 152 shows how it is working.
Using MCEdit, you can go back to your original spawn point by using "Move Spawn Point" on the hotbar and select "Goto Spawn". Then you can follow your history to try to figure out where your bed is.
If you really can't figure out, you can try the following MCEdit Filter. It will help you find your bed, but may actually take quite long (probably no less than a few minutes).
displayName = "Find beds"
inputs = (
("Search the whole world regardless of bounding box", True),
)
def perform(level, box, options):
if options["Search the whole world regardless of bounding box"]:
i = level.getAllChunkSlices()
else:
i = level.getChunkSlices(box)
print "Finding beds..."
for (chunk, slices, point) in i:
if blockExistInChunk(chunk, 26):
(x, z) = chunk.chunkPosition
print "=> Bed found near x={0}, z={1}".format(x * 16 + 8, z * 16 + 8)
print "Stopped finding beds."
def blockExistInChunk(chunk, blockId):
for a in chunk.Blocks:
for b in a:
for c in b:
if c == blockId:
return True
return False
Save the file under the filters directory in MCEdit with name findbeds.py, then go to MCEdit, use Filter on the hotbar, select Find Beds and click Filter. Now watch the console (the white on black window) and it will output the approximate coordinates of where beds are found.
Sample output:
Finding beds...
=> Bed found near x=-440, z=-600
Stopped finding beds.

Target selectors allow you to specify a
typeargument. You'll also need to use@efor entities, rather than@awhich is only for players.The following command should work:
