Well, sometimes I want to fight something else, but I don't really have Lua knowledge yet.
Like on the orbital map, I want stuff to just, fall down, despite not being defined in Lua.

So, is there anyway to accomplish this without editing the Lua file?

no, because the activities type is GAScripted, meaning the lua file controls everything.
you should be able to copy code out of fort malagar (sp?) easily enough though, i wouldnt be surprised if that code worked flawlessly unedited, because of the closeness to the X origin.
sorry this isnt very well worded..
