=== Country codes === | |||
Zandronum 3.1 introduces the ability to server hosts to specify the country their server is located in via a new CVAR, <tt>sv_country</tt>. This was introduced to allow hosts to combat the inaccuracies of IP geolocation that launchers rely on. This value is specified to launchers via the new <tt>SQF2_COUNTRY</tt> field, which can have the following values: | |||
* '''an ISO 3166-1 alpha-3 country code.''' Note that Zandronum doesn't validate whether the country code supplied in <tt>sv_country</tt> is a registered country code. If the launcher does not recognise the given code, then it should display a generic "unknown" flag. | |||
* '''the value <tt>XIP</tt>''', which suggests to the launcher that it should attempt IP geolocation to determine the server's country. The default value of <tt>sv_country</tt> will cause it to return this by default, to preserve existing behaviour and make it easier for casual hosts. If geolocation is unsupported, disabled, or fails, then a generic "unknown" flag should be displayed. | |||
* '''the value <tt>XUN</tt>''', in which case the launcher should display a generic "unknown" flag. | |||
