World server

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.	127.0.0.1 (local universe) IP address on http://www.whatismyip.com/
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

See also: List of 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	Description	Valid values
allow_passthrough	Whether passing through objects by holding SHIFT is enabled	0 for false, 1 for true (default)
avatar	Object to use as users' 3D avatar (3D representation)	Relative object name on the specified path with extension, e.g.: p1cube0100.rwx ../avatars/cy.rwx dog.md2
farplane	Far clipping plane distance; how far from the camera the ground and avatars are rendered	Any float value
nearplane	Near clipping plane distance; how close to the camera the ground and avatars are rendered	Any float value (0 may cause glitching)
fov	Field of view; how wide an angle the scene is visible to the camera	Any integer value
ground	Field of view; how wide an angle the scene is visible to the camera	Any integer value
fov	Field of view; how wide an angle the scene is visible to the camera	Any integer value
ground	Object to render as the "ground" or as static scenery, irrespective of user's visibility	Relative object name on the specified path with extension, e.g. ground.rwx
groundrepeats	If the ground object repeats infinitely, to cover the world with the object	0 for false, 1 for true
objectpath	Resolvable HTTP address to a server that provides the world's assets via the HTTP protocol, such as an object path	Any valid HTTP address, e.g. http://localhost/ http://objects.activeworlds.com/aw/ (alphaworld path) http://myop.no-ip.org:8282
skybox	Prefix name of a set of textures used for the skybox	Relative JPG texture name on the specified path with extension, e.g. sky_hd, which will load: sky_hd_fr.jpg sky_hd_bk.jpg sky_hd_lf.jpg sky_hd_rt.jpg sky_hd_dn.jpg sky_hd_up.jpg
