If you're allowed to do it, workshop items can be imported into the modding section. Go to modding -> import and select the (subscribed) item in question. You can do this with all items you have created yourself, and with items marked as extractable by their creator.

But what if I wanted to extract the files from the main game?

Our official levels are not extractable. If they were, we would have certain quality requirements regarding how they're made and this way we can supply content faster. However, we see the need for examples - so please let us know if you are interested in a particular feature/level!

Then how are we supposed to make complex levels from scratch if we don't know how they're set up? Like arenas? Boss fights?

There is definitely a need for examples - we're working on it.

In the meantime, we have opened the arena "No Escape" and cleaned it up a bit so you can take a look. Arenas use scripts to realize their endless, increasingly difficult spawns, as this level shows.

Please note that we do not consider this as accessible as a proper arena example should be. An example would be designed specifically to be more flexible and reusable, thereby limiting the need to understand scripting at this level. It is a huge topic as our scripting documentation (found in your modding folder) shows. Arenas are definitely on the hard side of things, compared to just making a bot say something or making the camera fixed.

In order to make reading scripts easier, there is a language definition file for Notepad++ available
HERE[pastebin.com]. You can paste it into a text-file called "universescript.xml" and import it in Notepad++ under "Language -> Define your language -> Import". "SU Script" will then be available as an option for source highlighting.

Hope this helps!

We just released our new map "Mothership". It is extractable and showcases a game-mode that does its own score calculations and implements separate stages of fighting against a boss that gets more and more abilities.
