[CLOSED] Removing blocks in SP

I have a SP game that I am using to build something for my outpost. It's a very large town and I am trying to make it so no mobs spawn anywhere inside of the walls I have around the town. To better do this I want basically the void all around so nothing else can spawn except inside the walls so i know where to add light.

Is there a fast way to remove the blocks around my build to expose just the void? I started it in a flat world so there wouldn't be much to remove. I was able to remove the blocks under the build using Schematica to replace all blocks with air blocks using auto print mode but this is the super long way. I also want to make sure that nothing in my build is touched.

Thanks in advance

You can use MC Edit to remove large chunks of the world at a time.

I assume this is a mod? Also is it difficult to use at all?

I use world edit for large scale builds. You can use it to select an area and delete it. It is a mod and is very easy to use. If you choose to use this, type "//wand" to get the tool (wooden axe) needed to select areas to remove. Pretty much all the commands with this mod require "//" before it, rather than just one /.

I can give you a step by step if you'd like. And I use the version that works with forge. The mod is called World Edit, and can be found here:

Thanks for that. Would I just click on opposite corners with that wand and they get removed?

It's an external program. It does take a bit of learning, but it's in general easy to use.
Here's a link if you want to look at it more: http://www.mcedit.net/

Yeah, pretty much. Left click is to select position one, and right click allows you to select position two. Basically, you can think of it as needing to create a cube (for ex: so upper left corner = position 1 and bottom left corner = position 2) as the selected area, then you can delete it. If you need some more help, just let me know and I'll try to explain it a little better for you

Wow that was ridiculously easy. Thanks so much!

And if you do go with the WorldEdit option, make sure you install WorldEdit CUI (I think it requires LiteLoader) which will actually show you what you're selecting [example]. And the WorldEdit commands would be:

//pos1 - one corner of the selection you want to make
//pos2 - the opposite corner of the selection
//replace dirt air - replace all dirt in that selection to air
//replace grass air - same but for grass
//replace bedrock air - for bedrock

If you mess up, use //undo.

or instead of //replace you can use //set air but that'll override what you already have built.

-------------------------------------------------------------------------------------------------------------------------------

If you don't want to use WorldEdit (which is probably better than this alternative), you can use the vanilla /fill command. Just be careful to avoid selecting what you already have built as it'll replace it all with air.

/fill <x1> <y1> <x1> <x2> <y2> <z2> minecraft:air is the command, I believe. Make sure you don't select your build though, because unlike worldedit there's no //undo command.

tl;dr /fill is quicker but worldedit is safer and better
edit: late but oh well

Ya I tried /fill command for other things but the area is pretty tiny. Like you couldn't even do an entire res worth of blocks. At most approx. 8 levels. But I like the undo option lol Few times I've had to load an older save. Thanks

No problem! Glad that I was able to help.
