I went to the End and it was empty. So I fell, switched to creative mode and flew to avoid dying.
I need to make a floating block to 1) build from and 2) give me a visual point of reference to search for the End island.
Is there a way to make a floating block using world edit, maybe by coordinates?
Try:
/setblock ~ ~ ~ minecraft:stone
Easily, using the region-select commands and then the region commands that set the area to a certain block. See the full list of commands.
For example: //sel cuboid, //pos1, move up one block, //pos2, //set 1 to make the air in a one-block region stone.
However, I doubt you'll find the End island this way. If the End is empty and you're not standing on a slab of obsidian, you probably got there through commands instead of an End Portal. I believe that the End doesn't spawn anything until you go through an End Portal once. So do that.
Just do /up <how high you want it to be>.
This will move you up a certain number of blocks. You cannot pass through walls with this command and a glass block will be placed at your feet to support you. (source)
do
/execute @p ~ ~ ~ fill ~1 ~2 ~1 ~-1 ~-1 ~-1 dirt
in a command block to make a platform underneath you
Just do /setblock ~ ~-1 ~ bedrock. You don't need a command block for that, and you don't need world edit.
Try /fill [x1] [y1] [z1] [x2] [y2] [z2] [block]
You can fill up to 32,000 blocks. However, it will only appear in a rectangular prism.
Im not sure why the gent saying "/up" was downvoted. Perhaps because the full command would actually be "/up 0" or "/up 1" but .. that is generally the command that you use with world edit or as he said .. essentialls you can also setblock but i find /up 1 a lot quicker in general.
You can use /up if you have Essentials.
