Attention: This is about the Milestone 1.9 and later editor NOT about the editor built into SuperTux 0.1.x.


Generic

Overview of the Editor, click to enlarge

How do I move around in a level?

Click and drag with the middle mouse button.


Tiles

How do I add tiles to a level

Click on the layer you want the tiles on and select the tile you want from the Tiles Tool.

How do I filter the the tiles so I can find a specific one?

With the Tiles tool selected, there is a combo box above the pane with all of the tiles in it. This combo box contains categories (called tile groups) which filter what is displayed in the pane.

How do I hide tile layers?

Click on the small eye (EditorEyeIcon.png) in the layer listing to adjust how hidden a layer is. Options are shown, semitransparent, and hidden.

How should I place the tiles for the end-level structures?

The best way to learn this is to look at existing levels. For the exit tree in MS2 the best place to look at is levels/test/tree-exit.stl at this point. Also note that using tiles for triggering the end sequence, although still supported, is no longer necessary. See What is the SequenceTrigger object for?

How do I add a new tilemap?

Tilemap.png

Select the tilemap object and place it like a normal object anywhere in the level. The result will be a new that a new tilemap is created.


Objects

How do I easily align an object to the grid?

Press the Control key while moving an object to snap to every 16 pixels. Press the Shift key to snap to every 32 pixels.

What is the SequenceTrigger object for?

Sequencetrigger.png
The SequenceTrigger object is used to define the areas that start and stop the end sequence (Tux walks into Igloo / Exit). The sequence names for that are "endsequence" and "stoptux", respectively. Also, you can use "fireworks".

What is the SpawnPoint object for?

Spawnpoint.png
The SpawnPoint object is used to define places where Tux could "spawn". This is used to mark where Tux should start in the level, the destination of doors and more. The spawnpoint where Tux will start on loading the level must be named "main" and be in the sector called "main".

How do I change the background image?


Other tools

How do I use brushes?

EditorBrushIcon.png

Brushes are used to clean up edge tiles. The brush tool does that by replacing a chosen 3x3 section of tiles with the best of several "good-looking" patterns stored in so-called brushes. Keep that in mind when working with brushes - a brush will never apply a pattern it does not know about.

There are already a few brushes in trunk/supertux-sharp/data/brushes that know some valid patterns e.g. for earth tiles or snow tiles. Load one in the level and then drag it over tiles to correct edge tiles of rough tile "blocks".

Note that the brushes are incomplete, so you might need to fix some things manually. If you used a pattern a brush did not yet know, you can add it to the list of known patterns by dragging a selection around the new pattern(s) with your right mouse button. All patterns in the selected region will be added to the list of valid patterns for the currently loaded brush. Because patterns are currently 3x3 tiles in size, your selection obviously has to be at least 3x3 tiles big. Also don't forget to save the brush afterwards or your changes will be lost when you deselect the brush.

To create a new brush you currently got to "train" an empty one:

  1. Make a level that looks good.
  2. Select the tilemap you placed those tiles in.
  3. Load the brush trunk/supertux-sharp/data/brushes/empty.csv
  4. Right click and drag to select the area to get tiles from.
    • The minimum size for a selection that works is 3x3 tiles.
  5. When you are finished save the brush.

Note that a good brush would need several thousand patterns.


Sectors

Where are the sector tabs?

Near the top of the editor. The default sector in a level is called "main" and is the sector where the game will start.

How do I resize a sector?

Right click on the tab for the sector and select "Resize".

How do I create a new sector?

Right click at the sector tab area and select "New".

How do I delete a sector?

Right click at the sector tab for the current sector and select "Delete".


Operating system specific notes

I'm on OpenSUSE and I get a message about that it couldn't load gtk-sharp

Could not load file or assembly 'gtk-sharp, Version=2.10.0.0, 
Culture=neutral, PublicKeyToken=35e10195dab3c99f' or one of its dependencies.

If you are on OpenSUSE and get a message like this you might want to try this and the note directly below it as well.

We (the developers) are unable to reproduce the problem but we do not use OpenSUSE. Try asking the OpenSUSE developers about what is going on there.

Does the editor work under Mac OS X?

Yes, it does, but the setup is complex; you will have to do the following:

  • install Apple's X11
  • download and build Gtk and its dependencies (Glib, Pango, Cairo, Atk, Gdk and maybe more)
  • download and build Mono and GTK#
  • download and build the editor

Since the Mono project doesn't pre-package Gtk# and its dependencies with the OS X installer, we are unable to provide a nice editor package. Additionally, we offer no official support, so no one might be able to help you on the mailing list if the editor crashes due to an OS X-specific problem.

Does the editor work under Microsoft Windows Vista?

Yes, but it requires a complete setup. you will have to compile some GTK# programs amongst other things. We are able to provide a package.


Bugs and Errors

Attention: For any bug reports where please provide the full backtrace (if one exists) when reporting at our bugtracker

I get an error about "Object reference not set to an instance of an object"

This can be several things:

  1. Check that the paths to the supertux data directory and to supertux itself in the editor preferences are correct.
  2. If you run it under mono (unless you know that you don't do it, you probably do run it under mono) check that the mono version is at least 1.2.2.1.


If any of the above didn't solve the problem and you manage to recreate the error, report the bug with at least this info:

  • Full backtrace
  • What you did to cause the bug
  • What OS and OS version you use
  • What versions of mono, the editor itself, GTK and GTK# that you use

These types of bugs can not be solved without that info (and sometimes we might need more details than that, so please check back at the bug once day or so if there is any more info asked for).
