+- Level editing for SuperTux -
+http://super-tux.sf.net/
+
+Last update: April 26, 2004
+
+This document describes both the level format and
+the level editor.
+
+= LEVEL FORMAT =
+
+The level format used to be pretty easy to understand, but it
+is now more complex. Anyway, should be pretty useful to know
+a bit of it, when you want to do stuff just as to just change
+the author's name or something small.
+
+It uses the Lisp syntax and is pretty intuitive. Here have a
+look at a quotation:
+(Comments can be made using ';')
+
+; This is a comment!
+(supertux-level
+; some level info: version, author and the level's name
+ (version 1)
+ (author "Ingo Ruhnke")
+ (name "Night Chill")
+; number of tiles used (currently the height has to be 15)
+ (width 515)
+ (height 15)
+; Tux's start position
+ (start_pos_x 100)
+ (start_pos_y 170)
+; Background image; if none is specified, the color below will be used
+ (background "")
+; Music file
+ (music "Mortimers_chipdisko.mod")
+; Colors, as you can see you can have different colors in the top
+; and in the bottom, thus creating a gradient
+ (bkgd_red_top 0)
+ (bkgd_green_top 0)
+ (bkgd_blue_top 0)
+ (bkgd_red_bottom 120)
+ (bkgd_green_bottom 120)
+ (bkgd_blue_bottom 0)
+; Time (it is not in seconds!)
+ (time 300)
+; Gravity to be used (you should let it stay in 10 for ordinary levels)
+ (gravity 10)
+; The particle system draws images that simulate weather effects
+; As of the writing of this text, both "snow" and "clouds" are supported
+ (particle_system "snow")
+; Theme is the tileset that is used
+ (theme "antarctica")
+ (interactive-tm
+ ; here goes a lot of numbers that are the tiles places
+ )
+; Reset points; there can be more than one
+; Reset points are positions where the player passes through and
+; if he dies, he will be back to there. They are invisible
+ (reset-points
+ (point (x 6988) (y 222))
+ )
+; Objects include enemies, may include more stuff in the future
+; just as moving plataforms...
+ (objects
+ (mriceblock (x 13919) (y 384))
+ (mriceblock (x 14258) (y 366))
+ (mriceblock (x 12996) (y 248))
+ (mriceblock (x 13058) (y 250))
+ (mriceblock (x 12933) (y 245))
+ )
+ )
+
+
+= LEVEL EDITORS =
+
+USING THE BUILT-IN LEVEL EDITOR:
+--------------------------------
+
+When opening the leveleditor, a menu will appear. This menu
+can be used to select or add level subsets. A level subset is
+a collection of levels. Subsets can be chose during gameplay
+when starting a game.
+
+After selecting the subset, have a look at the level editor.
+The button bar in the right is the place where you can control
+the actions related with editing. You can select levels and add
+throught there.
+
+To select tiles (foreground or background) and enemies, the button
+bar is the right place. There you can also save, test and setup
+the level. It is also possible between two selection cursors! Give
+a try to both. A right click in a button bar button will give you
+a description and a shortcut for it.
+
+To change a tile, just press the tile you want to change with a
+left mouse click. The current tile will be used. Depending
+on the selection behavior, you can or not select more
+than one tiles.
+
+To scroll, you just have to point over the two arrow buttons, or
+use the right button click.
+
+There is a small help that can be reached by pressing F1.
+
+To go back to the menu, just press Esc.
+
+The levels are saved under a .supertux/levels directory in
+your home directory.
+
+FIXME: this description of the built-in level editor are
+out dated. Anyway, it is yet being developed.
+
+USING FLEXLAY:
+--------------
+
+FlexLay is an external project (it even uses different libraries)
+that is developed by Ingo Ruhnke and supports a lot of different
+games, including SuperTux (or else we wouldn't mention it :) ).
+
+Anyway, it is pretty easy to use and is a lot more advanced than
+the internal one. So, if you are considering doing a few levels
+for us, it would be a good idea to check this out.
+
+There isn't currently any webpage for it, just go to our webpage and
+you should find a download of this program.
+
+You can also get the latest development copy from the Subversion
+source tree:
+ svn co "svn://clanlib.org/Games/Windstille/trunk/flexlay/"
+
+The only cons it has is that you have to have an accelerated
+videocard (with the drivers working, obviously). For linux,
+we advise nvidia videocards with the use of nvidia's closed
+drivers. ATI drivers should be enough to run this game though.
+
+
+= CONCLUSION =
+
+To sum up, go build lots of levels and HAVE FUN!!
+
+Please, send your levels or any art, including sketches, you
+have created to the SuperTux mailing list.
