Omen is a map editor for Minecraft. It doesn't support Alpha maps yet - only Creative and Indev levels. I am looking into updated version with infinite map support.

Be sure to backup any .mclevels you modfiy with Omen - there is a known issue with chests.

Multiplayer maps are not affected.

UPDATE - 08/02/10- Version 0.7.0 out!

Download it here

I got the worst of the bugs! I think.

.mclevel support
Environment Settings
New blocks

Firstly, I've changed the name - it's now Omen. This is a better name, but as I'm planning on opening the code up to the community it also removes my username from the name.

I'm working on putting together some proper documentation together too, not in the zip but expect it. Now I need to sleep. Feel free to find many, many bugs!

v0.5.0
Additions:
Straight and Bezier (curved) line tools
New map options, including 8 flat map presets and 5 map generators
A proper menu and changed layout
Heightmap export
Bulk import/export of layer PNGs

Fixes:
Rendering glitch when drawing
Icons not appearing

Additions:
PNG importer will now pick nearest colour
Last edited block now appears in status bar

UPDATE - 23/06/09 - Version 0.4 is now out!

File removed - see newest version above


UPDATE - 22/06/09

It will be out tomorrow - really! Everything is more or less done, need to do some testing then bundle it up. I've work tomorrow, so it won't be out until (Monday) night.

All the features that I said I would add are done apart from tree prefabs (which I will do tomorrow) and animated gif support (which I'm putting on hold for now). In addition, I added multiple views, a dropper, zooming, support for creating maps from scratch plus all the new blocks.



Here's how the editor looks on a Mac:



Here's it in Vista:



It was developed on the Mac and works fine, but is having some drawing problems on Vista so I need to fix that.


Original Post

Over the weekend I modified a previous program I had written to be a map editor for Minecraft. It's not yet done as there are still some things I want to do with it, but it should be out soon. I thought I'd announce it here as a couple of other people seem to be working on the same thing.


So far OME can:

Load and save maps
Create blank maps
Displays slices of the map as images, and allows scrolling between layers
Allows for drawing in 2d and 3d with round and square brushes with any block type
Can copy layers up and down
Can import and export layers as PNG images (to allow editing in photoshop etc)
Can generate maps from greyscale heightmap images

Prior to release I hope to add:

Support for animated GIFs (each frame representing a layer of the map)
Flood Fill/Paintbucket in 2d and 3d
Block replace brush
Tree prefabs
A better interface
Control over map properties (size, spawn points etc)

Below I've posted pictures of a map of Europe (you can download it here) I made from a topographic heightmap




Here is the same map viewed in OME:

Like I said, the interface sucks just now and I plan to replace it, though I may release this version first depending how long it takes me.

Also, just for fun - done using the PNG importer:

The Legend of Zelda overworld map:




If anyone has any feedback or suggestions for features that would be awesome!

Do Want.

Kinda a cool idea, but hey, DING DING, isn't this game about creating stuff in-game :S?

Damn people are lazy. :3

Damn. We need more people here like you.


Keep it up!

:biggrin.gif:

Crazy.

Keep up to good work :smile.gif:

Amazing!
When do you think a beta of it will be released?

THIS IS INSTANT WIN! I love the Obama one :biggrin.gif:

This is really awesome. This will allow easy map-making. :biggrin.gif:

Release this asap before I spaz out and start to kill babies @[email protected]

I want to make some halo maps now.

Thanks for the support guys! I'm going to try and have a version out in the next couple of days. The GUI overhaul can wait for the next version.

Any mac love, or will I have to try running this under crossover?

It's a Java program, so it will run under any OS with Java and the Minecraft Server installed.

This looks very promessing... do want.

Wow. This means the /b/tards might actually be creative to troll people! Imagine it, you join a server and the whole map is Pedobear.
