|
# OVERVIEW
|
|
Controls fog that affects the entire map.
|
|
|
|
# KEYS
|
|
- "targetname" : Name
|
|
- "target" : Name of an entity in the map that light will point at.
|
|
- "fogenable" : Will make the fog start active if not 0.
|
|
- "fogstart" : Distance from the camera of where the fog starts.
|
|
- "fogend" : Distance from the camera of where the fog ends.
|
|
- "fogmaxdensity" : Maximum fog density. Value between 0.00 and 1.00.
|
|
- "farz" : Clip anything after the specified distance.
|
|
- "fogcolor" : Primary color of the fog in RGB255. E.g. '255 0 0' for red.
|
|
- "fogcolor2" : Secondary color of the fog in RGB255. Only used when 'fogblend' is 1.
|
|
- "fogblend" : Whether or not to blend between fogcolor and fogcolor2.
|
|
- "fogdir" : The fog directon for the secondary color. Only used when 'fogblend' is 1.
|
|
- "use_angles" : If we should use the 'angles' key instead of 'fogdir'. Only used when 'fogblend' is 1.
|
|
|
|
# INPUTS
|
|
- "TurnOff" : Turns the entity off.
|
|
- "TurnOn" : Turns the entity on.
|
|
- "Toggle" : Toggles the entity to an on/off state.
|
|
- "SetStartDist" : Sets fogstart.
|
|
- "SetEndDist" : Sets fogend.
|
|
- "SetColor" : Sets fogcolor.
|
|
- "SetColorSecondary" : Sets fogcolor2.
|
|
- "SetFarZ" : Sets farz.
|
|
|
|
# SPAWNFLAGS
|
|
- EVFOGCTL_MASTER (1) : If specified, this one will always take priority over
|
|
any other active fog controllers... currently unused.
|
|
|
|
