I was looking at src/common/global.cxx and there are server variables not documented in wiki (I couldn't find corresponding man page). Are they deprecated or what?
_fogNoSky will do what it says. Fog is not draw on the sky. I've used it in several maps, makes for interesting environmental effects. -set _fogNoSky 1 in your map config will turn off fog drawing on the sky. The default is fog everywhere.
_ambientLight none
This one doesn't seem to be used anywhere in the latest 2.0.x code.
_disableSpeedChecks 0
This allows disabling/enabling the speed kicks
_disableHeightChecks 0
This allows disabling/enabling the "too high" check (or maybe the out of the world boundaries check in general)
_drawGroundLights 1
If set to 0, lights on the ground (such as the light from bullets) will not be drawn
_enableDistanceCheck 0
Distance checking tries to verify if a player moved too far between updates (as in, cheating). I'm not sure how well tested this feature is, which may explain why it's off by default.
_endShotDetection 5
This setting controls how many "end shot" messages can be sent without corresponding deaths (or other reasons, such as a shield drop).
_spawnMaxCompTime 0.01
This controls the maximum amount of time to attempt finding a safe spawn location. If this time is exceeded, the tank will just get dropped in from maximum height. The time should be in seconds, so the default is to only wait for 10ms.
_spawnSafeRadMod 20
_spawnSafeSRMod 3
_spawnSafeSWMod 1.5
These control some of the spawn code to try to prevent spawning people near instant death (like not spawning someone on top of a player with SR)
_speedChecksLogOnly 0
If set to 1, someone moving too fast will not get kicked - it will just log it to the stdout.
