= How to create Orxonox Levels =

To create a level in Orxonox is really easy. One does not have to program anything or compile the code again, because our levels are created with XML-Files. There the objects in the level can be defined. On this page we explain what one can do with the XML-Files and how to create a new level for Orxonox with them.

The objects we can add are rooms (BSP-files), spacecrafts (OBJ-files) and moving objects (MD2-files). How to that exactly is best explained with the examples below.

If you're interested in creating rooms and BSP-levels check out this page: [wiki:MappingForOrxonox Maping for Orxonox with GTK-Radiant]

== Adding a menu entry ==
Before you can play a level in Orxonox you have to add the level as a menu entry in the game. To do that you have to alter the DefaultCampaign.oxc file in the data/levels directory (or data/worlds in older versions).[[br]]

Below there is a example for that file:
{{{
#!xml
<Campaign>
  <name>default</name>
  <identifier>0</identifier>
  <description>The one and only default debug campaign</description>
  <WorldList>

    <GameMenu>
      <identifier>0</identifier>
      <name>GameMenu</name>
      <path>levels/Menu.oxw</path>
      <nextid>1</nextid>
    </GameMenu>

    <SinglePlayerWorld>
      <identifier>1</identifier>
      <nextid>2</nextid>
      <name>Demo Mountain Lake</name>
      <path>levels/sp_demo_mountain_lake.oxw</path>
      <menu-entry>1</menu-entry>
    </SinglePlayerWorld>

    <MultiPlayerWorld>
      <identifier>2</identifier>
      <nextid>0</nextid>
      <path>levels/mp_level_arena.oxw</path>
    </MultiPlayerWorld>

    ...

  </WorldList>
</Campaign>
}}}
Now to add your level you have to add an !SinglePlayerWorld (or !MultiPlayerWorld) entry to the !WorldList. Be sure to add an identifier a name and the most important: the path of your OXW-file. The number of the identifier and the menu-entry have to be incremented. Close every <tag> you open.

== XML level file (OXW) syntax ==

Level files have the extension OXW (for '''O'''rxono'''X''' '''W'''orld). The order of the things you add does not matter.
