World server

From Virtual Paradise Wiki
Jump to navigation Jump to search

The world server is the software that hosts a virtual world, connected to a Virtual Paradise universe server.

worldserver.info

The world server reads important connection and database settings from worldserver.info, which is parsed as a Boost property tree. The file can be edited in any text editor such as Notepad++.

Values

Key Subkey Description Valid values
server port Port for clients to connect to, to access all worlds on this server. Any number between 1 - 65535 (values below 1024 may conflict with other services such as HTTP servers)
host Only for client version 0.3.22 and newer Host name for clients connecting via the universe to resolve and connect to, to access all worlds on this server.
  • localhost (local universe)
  • example.no-ip.org (free dynamic hostname service)
  • auth.myowndomain.org
ip Optional; see 'host' The IP address clients connecting via the universe should connect to, to access all worlds on this server. Should not be used if router does not allow NAT loopback.
database backend Optional Database driver to use internally
  • obdc
connection_string Optional Standard string used to describe database driver or provider to use, along with relevant information such as database name and login information See http://www.connectionstrings.com/ for examples
database_type Optional Type of database to use
  • sqlite
connections Optional Amount of persistent connections to keep to the database. Ideally, never set higher than amount of threads. 1 - 255
threads Optional Amount of threads dedicated to I/O on the database connections. Ideally, set to at least the number of CPU cores (physical and virtual) available on the system. 1 - 255

Per-world settings

The world server keeps individual settings for each world in the Setting table of the database. For each row, one column defines the ID of the world, the key and the value respectively.

The values are never used by the server; they are sent to the client. Each value is a string with a maximum of 255 characters, however the client requires some values to conform to a particular format to be valid.

Values

All values are optional
Key Type Default Value Description
allow_debug_menu boolean 1 If true, allows the debug menu to be used
allow_flying boolean 1 If true, allows the user to fly up and down by using the + and - keys.
allow_passthrough boolean 1 If true, allows the user to move through objects and terrain by holding the shift key
avatar string DEPRECATED - Object to use as users' 3D avatar (3D representation). Relative object name on the specified path with extension, e.g.:

  • ../avatars/cy.rwx
  • dog.md2
avatars_file string avatars The name of the avatars list YAML file on the object path, with the default value the file will be loaded from avatars/avatars.yml, this allows the same object path to be used with multiple different avatar list configurations
entry_point decimal 0 0 0 0 Defines the entry point, in coordinates (X Y Z Yaw), for a world.
farplane decimal 40.0 Far clipping plane distance in decameters; how far from the camera the ground and avatars are rendered

fog_density decimal 0.0 Fog density (only applies to exponential fog modes)
fog_end decimal 0.0 The distance at which fog ends (only applies to linear fog mode)
fog_mode string none Valid values are: none, linear, exp/exponential, exp2/exponential2 (exponential squared)
fov decimal 50 Field of view; how wide an angle of the scene is visible to the camera (in degrees)
ground string ground (or empty if terrain is enabled) Model name for the world "ground" object, a base object that is always rendered regardless of the user's distance from it (e.g. ground.rwx)
groundrepeats boolean 0 If true, the ground object repeats infinitely, to cover the world with the object (center the ground object at the nearest point on a 30m grid)
nearplane decimal 0.03 Near plane distance in decameters; how close to the camera the ground and avatars are rendered (0 may cause glitching)
objectpassword string Password for extracting password-protected ZIP files from the object path
objectpath string http://objects.virtualparadise.org/vpbuild/ Resolvable HTTP address to a server that provides the world's assets via the HTTP protocol, such as an object path (e.g. "http://localhost/", "http://objects.activeworlds.com/aw/" (alphaworld path), "http://myop.no-ip.org:8282")
old_walking_speed ??? ??? ???
override_visibility decimal Force a fixed visibility value (specified in decameters, the visibility menu in the user's client will be disabled)
recommended_light_count decimal 0 If set, displays a warning in chat if the maximum light count in settings is not set to the world's recommended value.
recommended_per_pixel_lighting boolean 0 If true, displays a warning in chat if the user's graphical renderer in settings is not set to one that supports per-pixel lighting.
run_speed decimal 2.4 If set, changes the speed at which users run.
sky boolean 0 Enable gradient sky

skybox string Prefix name of a set of textures used for the skybox. A direction and a file extension is added to the prefix for each of the skybox textures (_fr, _lf, _bk, _rt, _up or _bt). The files are downloaded from the textures folder of the world object path. For example "sky_hd", will load:
  • sky_hd_fr.jpg
