Expert (or any other) mode

I was wondering if there was a way to make an Expert (or any other) mission list in any mod. Please help.

Sure thing!
Luckily for you, the game's code takes care of mission types in an extendable manner, so adding an expert mode is trivial.

There's only a few things you need to do to get an "Expert" mode working:

• Create an expert directory in marble/data/missions/ where the game will search for expert missions.
• In your playMissionGui, add a button for your Expert difficulty.
• Set the button's command to:
  Code:

  $MissionType = \"expert\"; buildMissionList();
  Replace "expert" with whatever difficulty you plan on adding, but don't forget to keep the backslashes before the quotes!

Let me know if this works for you, or if I need to explain anything better.

Ok, I get that bit, but how would you get it to build the mission list if using the Choose Gui (chooseGui.gui) or any other gui.

If you're making your own custom GUI then I guess you'd have to use your own code to find the missions. As far as I know, chooseGui (by default) is an incomplete difficulty selector screen (unless you mean startMissionGui, in which case you're in for a BARREL of fun). The only thing I can really recommend at this point is a for-file loop: Sorry if I couldn't help much, but I can't really help with custom interfaces/code without prior knowledge of your setup.
