Galaxy API Documentation and Map Editor here

Yup, that's correct! Interested in learning about or furthering SC2 Map making? Myself and a few others over at Curse's new Mapping website,, have a ton of the Galaxy API documented as well as some XML Modding documentation. In addition, we have quite a few projects that have already begun. As of right now, Mapster has achieved a few "world firsts", if you will.

Currently, Mapster is the first and only website to offer a Custom Tower Defense Map, created by our very own.

We also have the first and only Custom Tileset:

Now on to what most of you are probably looking here for; the Map Editor. Our Editor, dubbed MilkyWayEdit, can do the following:

  • Edit all Map Info/settings including Player Info (race, position, color)
  • Edit Galaxy files
  • Edit all GameData XML files
  • Place and edit Units
  • View 3D Unit-Models

You can view it in action here.

If you're interested, join us in the Mapster Forums or on IRC at #sc2mapster.


I keep popping up on this site from time to time.

Your map editor thing doesn't have syntax highlighting.

Yeah, that's on our to-do list. Keep in mind, it's in development, :p. Our main priorities was getting it to load the galaxy files first, and then working on editing all data.

The program doesn't launch SC2. It'll crash (at least it does for me).

Odd, what error message do you receive? You may need to run MWE in Administrative Mode. It checks the registry for the correct SC2 filepath.

I get:

Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

The system cannot find the file specified.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the section.
The application must also be compiled with debugging

For example:

< jitDebugging="true" />

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Running as Administrator does nothing.

Edit: Looking in the settings file, it seems that this program doesn't automatically update the settings...

Edit2: After fixing paths in settings.txt, I get: You cannot specify more than one file path as a command-line argument from LazyTown Loader.

Well, the settings.txt file is only there if the Editor cannot read the registry properly. That also shouldn't happen though. I'll look into it, thanks.

When exactly do you receive this, btw?

Sixen, you're that person who is in the Tech Forums in

I'm interested. Going to look at it, after breakfast.
