Can we have tutorial on how to make a the main.lua file?

SPTX:
What we have here doesn't explain anything about the needed "run" function, for example.
It would be nice to have such things explained.

tehtmi:
"run" is a special function required "single" type levels that does what the OnCreate hook normally does for levels that are declared with register_level.  For other level hooks, "single" levels can just use the corresponding module hooks since there is only one level anyway.

Typically, the "run" function will set up the map (maybe with a generator.place_tile call) and place the player (level:player(x,y)).  Any other stuff is typically just as effective if it appears in the top-level scope of main.lua (or a required file).

As far as making a tutorial, we'd love to do it, but it is just a matter of finding the time, but feel free to continue asking questions.

That's what I figured out. So I used episode instead, but it seems I have to script the whole episode myself. Isn't there a way to just call for the default one?

You can call DoomRL.OnCreateEpisode in the OnCreateEpisode hook to create the default episode (and use DoomRL.OnGenerate to use the default generator).

I tried this
--- Code: ---function SPTXContentPack.OnCreateEpisode()
DoomRL.CreateEpisode()
end
--- End code ---
But get this error : main/lua6: attempt to call field 'CreateEpisode' (a nil value)
Line 6 is "DoomRL.CreateEpisode()". Do I have to send any argument? I tried DoomRL.CreateEpisode(1) for shit and giggles, but it lend the same error.
