Documentation for 0.2.0 version of svg2lvl
- Inkscape (>= 0.44)
- Python (>= 2.4) (not required under Windows, it's included with Inkscape)
- Svg2lvl converter and inkscape extension version 0.2.0
- available from http://xmoto.tuxfamily.fr/ or directly from http://prdownloads.sourceforge.net/xmoto/svg2lvl-0.2.0.tar.gz?download
You have to install the svg2lvl inkscape extension.
We suppose that you have downloaded the svg2lvl-0.2.0.tar.gz archive into ~/download/
$ cd ~/download/ $ tar zxvf svg2lvl-0.2.0.tar.gz $ cd svg2lvl-0.2.0 $ mkdir -p ~/.inkscape/extensions/ $ cp *.inx *.py ~/.inkscape/extensions/ $ ln -s /usr/share/inkscape/extensions/bezmisc.py ~/.inkscape/extensions/bezmisc.py $ ln -s /usr/share/inkscape/extensions/inkex.py ~/.inkscape/extensions/inkex.py
Then, you can launch inkscape.
Extract the svg2lvl-0.2.0.tar.gz archive you have downloaded with your preferred extraction tool (unrar, 7-zip, ...). Go to the share/extensions/ directory inside your Inkscape installation. Copy the .py and .inx files from the archive into that directory.
Then, launch inkscape.
Mac OS X
Python 2.4, download the .dmg of Python 2.4 for Mac OS X: http://www.python.org/getit/releases/2.4.4/
Copy all of the .py and .inx files from the Svg2lvl.tar.gz file, and paste them into the Inkscape extensions folder.
Then launch Inkscape.
Test if the installation is ok
- Check in the 'Effects' menu that there is an entry 'X-moto'
- Do 'Save as...' (Shift-Ctrl-S), and check that you can select the 'X-Moto Level (*.lvl)' file format.
If the installation is not ok, please go to the IRC so we can help you find out why it failed.
Draw the level
Note that since X-Moto 0.2.4, you have to press F5 at the menu stage when you modify the Levels directory (if you make a new level for example)
You're ready to draw your level using Inskcape. See Inskcape howto's from the help menu.
Put level objects properties
Once your level is drawn, you have to put entities, blocks and sprites properties.
There is two ways of doing it. Manually or using inkscape effects.
Using inkscape Effects
The easiest way to change objects properties.
Select the objets whose you want to change their properties. Then go to the Effect menu and choose the X-moto sub-menu. From there you got other sub-menus to transform your objects into the desired type (Zones, Blocks and Entities).
Depending on the object type, its color changes. Colors are pretty ugly for the moment... but feel free to give idea about which colors could suit better. Adding a texture edge to a block adds an ugly green edge to the block in inkscape.
(Info: It just updates the object label (see next section for a better description)).
For example, we want to change the circle into a dynamic block using the texture Texture1 (it's a fake one, it doesn't exists). (Note that you can select more than one object at a time). First, we select the right entry in the X-moto submenu.
Then we put the texture name
And here is the result. To see it, right click on an object then select object properties.
The other way to change objects properties.
Select an object, right click on it, then select 'object properties'.
Properties are put inside the 'label' box. They are seperate with a '|'. If no properties are set, then the object is put as a block with default texture. You can also fill the 'id' box, it's useful if you write a lua script for the level, because you got the blocks, zones and entities names to use in your script.
WARNING : properties are case sensitive ! Write them with the exact case as show below.
A background block (it's a block in the background and the player can't interact with it) using the Dark Dirt texture:
A dynamic block using the default texture:
A block using the default texture:
(you have nothing to put in, let it blank (or let what inkscape puts in it))
A block using the Dark Dirt texture:
A dynamic block with grass on it and the Bricks texture
A block using the Dark Dirt texture and which grips like ice (grip values range is [1.0 - 50.0], the default value is 20.0. The smallest the value, the less grip is the block)
- size=float_number (the entity colision radius)
- param_name=param_value available params name are (there's more of them):
- z (for Sprite)
- name (for Sprite)
- style (for every entity)
- type (for ParticleSource)
A particle source throwing smoke:
A tree sprite put under foreground blocks
End of level:
- The only possible value for a zone
Generate level file
DISCLAIMER : Save you level in svg format too. .lvl is a loosy format, you'll loose informations about bezier curves, because there are remplaced with many vertex. Furthermore, inkscape can't open .lvl files (feel free to send a patch to correct this).
Launch the converter
In order to save your level in the .lvl file format, use the menu File -> Save as... (or use Shift-Ctrl-S) and choose the X-Moto Level file extension, put the level file name then press Save.
A new window pops, you have to put:
- level width : the level width in xmoto unit. play with it until you find the right value for your level
- smoothitude : the higher the value, the smoothest the level. But don't add to much vertex, because xmoto doesn't scale very well with big levels made with thousands of vertex... and became quite slow...
- lua script : the absolute path to your lua script (leave blank if your level doesn't have a lua script)
- level id : the level id (each level got a unique one)
- level name: the name of the level in the level list
- author: your name/pseudo
- description: short description of the level
- sky: the sky you want to use with your level
- rversion: the minimum xmoto version required to play this level (default to 0.2.0).
The rversion depends on the lua scripts functions you're using. (see Scripted_levels for a list of lua functions and the xmoto version where they are available)
Then your level file will be save in the place you choose in the Save as... window.
Disclaimer: There's a bug in Inkscape. The very first time you save a level in lvl, put something into the lua script box (default: None). Else Inkscape will abort...
Then, put your lvl generated file into your xmoto Levels directory, and you can play it (see how the grass is only added on the upper side of the block):
The script add a log file svg2lvl.log into your home directory.
