	The Osirion Project - Editing the world
</H1>
<p>
	One of the goals of the project is to create a game world that is
	easy to adapt and extend. At the moment of writing, the game reads the 
	world description from <i>ini/world.ini</i> and a list of buyable ships 
	from <i>ini/ships.ini</i>. These ini-files are plain text files that can be
	edited with any text editor.
<p>
	The world description files are server-side. This means that editing your local
	copies will not affect the world when you connect to a remote server. Someone
	connecting to your server will also receive your modified world.
<p>
	I recommend you do not edit the original game data, but to make a copy
	into your personal osirion directory. The files found in this directory will
	get precedence over the original game data. Your modified files will be used
	and the original files can still be updated when a new version is available.
<p>
	On Linux your personal osirion directory is <i>~/.osirion</i>. On windows, your
	personal osirion directory is the <i>home</i> subdirectory of the main distribution.

<h2>
	File structure
</h2>
<p>
	World description files use the windows ini-file syntax. These files contain one or more sections.
	Every section starts with a section name enclosed in square brackets and contains a list of 
	<i>value=key</i> pairs to describe the properties for the current section. 
	Lines starting with a semicolon are considered comments and are ignored.
<p>	
	For example, a section <i>planet</i> describing an iceworld:
<pre>
; The iceworld, a very dark and cold place
[planet]
label=iceworld
name=The World of Ice
radius=32
texture=planets/iceworld
</pre>

<h2>
	world.ini
</h2>

<p>
	The <i>world.ini</i> file contains a list of zone labels. A zone is a seperate compartment in the gameworld,
	like a solar system or a remote sector in space. It contains a single <i>world</i> section containting multiple
	<i>zone</i> keys.
<h3>
	[world]
</h3>

<table>
	<tr>
		<td class="wide"><i>zone =</i></td>
		<td class="narrow"><strong>[string]</strong></td>
		<td>the in-game label of a zone</td>
	</tr>
</table>
<p>
	<i>Note:</i> a label can only contain lowercase letters, numbers and underscores. Any other character is deleted.
	This applies to any in-game label in any .ini-file.

<pre>
; a world.ini example with two zones
[world]
zone=solarsystem
zone=remotesector
</pre>
<h2>
	zones/<i>label</i>.ini
</h2>
<p>
	Each zone has its own zone description file. The actual name of the file depends on the zone label. 
	If your <i>world.ini</i> contains the line <i>zone=remotesector</i>, the content of the zone with 
	the label <i>remotesector</i> would be described in the file <i>ini/zones/remotesector.ini</i>.
<p>
	The .ini-file containts a list of objects populating that zone, and the basic properties of those
	objects. In the context of the engine, such an object is called an <i>entity</i>.
<h3>
	[zone]
</h3>

<p>
	Every zone description file has a <i>zone</i> section describing a few of its basic properties:
<table>
	<tr>
		<td class="wide"><i>name =</i></td>
		<td class="narrow"><strong>[string]</strong></td>
		<td>the in-game name of the entity</td>
	</tr>
	<tr>
		<td class="wide"><i>sky =</i></td>
		<td class="narrow"><strong>[string]</strong></td>
		<td>name of the sky texture in <i>textures/env</i> directory</td>
	</tr>
	<tr>
		<td class="wide"><i>default =</i></td>
		<td class="narrow"><strong>[bool]</strong></td>
		<td>mark this zone as the default zone for the game, only one zone can have this key set to yes, can be omitted elsewhere</td>
	</tr>
</table>
<pre>
; remotesector.ini
; zone description file for the Remote Sector
[sector]
name=Remote Sector
sky=sky_texture
default=no
</pre>
<h3>
	[entity]
</h3>
<p>
	Entities come in two flavours: basic geometrical shapes and entities with models. Both have a similar
	definition and set of properties. A simple entity is considered decoration by the engine and won't change
	direction or location.
<p>
	Every in-game entity should have a <i>label</i> key. If the entity in question is going to be used as a base,
	or any object the could be referenced in possible scripting, it should have a unique label. The label
	should be lowercase and not contain spaces. A player-friendly name can be provided through the <i>name</i> key.
<table>
	<tr>
		<td class="wide"><i>label =</i></td>
		<td class="narrow"><strong>[string]</strong></td>
		<td>the in-game label of the entity</td>
	</tr>
	<tr>
		<td class="wide"><i>name =</i></td>
		<td class="narrow"><strong>[string]</strong></td>
		<td>the in-game name of the entity</td>
	</tr>
</table>
<p>
	Set the <i>shape</i> key to define a basic geometrical shape:
<table>
	<tr>
		<td class="wide"><i>shape =</i></td>
		<td class="narrow"><strong>axis</strong></td>
		<td>a 3d-axis with X, Y and Z lines.
	</tr>
	<tr>
		<td class="wide"></td>
		<td class="narrow"><strong>cube</strong></td>
		<td>a cube</td>
	</tr>
	<tr>
		<td class="wide"></td>
		<td class="narrow"><strong>diamond</strong></td>
		<td>a rotating octahedron with an axis</td>
	</tr>
	<tr>
		<td class="wide"></td>
		<td class="narrow"><strong>sphere</strong></td>
		<td>a polyhedron approximation of a sphere</td>
	</tr>
</table>
<p>
	The size of the entity can be set with the <i>radius</i> key:
<table>
	<tr>
		<td class="wide"><i>radius =</i></td>
		<td class="narrow"><strong>[float]</strong></td>
		<td>the radius of the entity in game units</td>
	</tr>
</table>
<p>
	1 game unit translates to 100m in-game, an entity with a radius of 0.5 
	would fit into a sphere with a diameter of 100m.
<p>

<p>
	An entity with a model can be created by setting the <i>model</i> key. The radius of a model is automaticly
	calculated:
<table>
	<tr>
		<td class="wide"><i>model =</i></td>
		<td class="narrow"><strong>[string]</strong></td>
		<td>filename of the model in the <i>maps/</i> directory, without extension.</td>
	</tr>
</table>

<p>
	The <i>color</i> key sets the primary color of the entity. This color will be used to draw the entity in case of 
	a geometrical shape, or to draw model faces that have the <i>common/entity</i> texture. The default entity colour is white.
<p>
	The <i>colorsecond </i> key can be used to set the secondary color of entities with a model.
<table>
	<tr>
		<td class="wide"><i>color =</i></td>
		<td><strong>[float] [float] [float]</strong></td>
		<td>primary entity color RGB values with in the 0.0 - 1.0 or 0 - 255 range</td>
	</tr>
	<tr>
		<td class="wide"><i>colorsecond =</i></td>
		<td><strong>[float] [float] [float]</strong></td>
		<td>secondary entity color</td>
</table>
<p>
	The <i>location</i> sets the in-game position:
<table>
	<tr>
		<td class="wide"><i>location =</i></td>
		<td><strong>[float] [float] [float]</strong></td>
		<td>x, y, z values of the entity location, z is up</td>
	</tr>
</table>
<p>
	1 game unit on the x, y, or z-axis translates to 100m in-game.
<p>
	Orientation can be set thought the <i>direction</i>, <i>pitch</i>, and <i>roll</i> keys:
<table>
	<tr>
		<td class="wide"><i>direction =</i></td>
		<td class="narrow"><strong>[float]</strong></td>
		<td>direction angle the entity is pointing to. 0 degrees is north, 90 degrees is west, default is 0
	</tr>
	<tr>
		<td class="wide"><i>pitch =</i></td>
		<td class="narrow"><strong>[float]</strong></td>
		<td>pitch angle, default is 0<td>
	</tr>
	<tr>
		<td class="wide"><i>roll =</i></td>
		<td class="narrow"><strong>[float]</strong></td>
		<td>roll angle, default is 0<td>
	</tr>
</table>

<h3>
	[planet]
</h3>
<p>
	A planet is spherical entity with a texture. and a default radius of 64. The planet globe will
	be rendered with lighting enabled.
<table>
	<tr>
		<td class="wide"><i>texture =</i></td>
		<td class="narrow"><strong>[string]</strong></td>
		<td>name of the planet texture in <i>textures</i> directory</td>
	</tr>

</pre>

<h3>
	[star]
</h3>
<p>
	A star is a spherical entity with a default radius of 96. The star globe 
	will be rendered fullbright and serve as the main source of light for the current system. 
	At the moment only one system light source is supported. If you define multiple stars, 
	the last one will serve as light source. Stars can have a texture.
<pre>
[star]
label=whitedwarf
name=White Dwarf
; light yellow

	Definition of the shopping list.

<h2>
	Textures

<p>
	The engine supports textures in the TGA, PNG and JPG file formats. The filename extension
	should be lowercase and the texture should be in 24bit RGB or 32bit RGBA format.
