Keyvalues

Enabled (Enabled) <choices>

Enable/Disable this Entity.

Determines is this entity enabled or disabled on spawn.

• 0: Enabled
• 1: Disabled

Shape Type (xogtype) <choices>

Determines shape type that use xog volume, BBOX or Ellipsoid.

• 0:0: LocalVolume BBOX
• 1:1: LocalVolume Ellipsoid

Examples

BBOX Ellipsoid

colorMode (colormode) <choices>

Determines color mode.

• 0:0:StaticColor
• 1:1:1DGradTexture
• 2:2: CubeGradTexture

Texture name Grad Texture (texname) <string>

Xog gradient texture name. The default is xen/effects/xen_sky_6_blurred_32.

colorTop (colortop) <color255>

Xog top color. This is the main color of xog that uses if Enable Height Blend KV is disabled.

colorBottom (colorbottom) <color255>

Xog bottom color. Requires enabled Enable Height Blend to be working.

Note:Top and bottom colors blending in xog center, for example with red and green colors the center of xog will be yellow.

distStart (diststart) <float>

distStart

Xog start draw distance.

Examples

distStart - 10. distEnd - 100. distStart - 70. distEnd - 100. distStart - 200. distEnd - 100.

distEnd (distend) <float>

distEnd

Xog end draw distance.

Examples

distStart - 10. distEnd - 100. distStart - 10. distEnd - 700. distStart - 10. distEnd - 2000.

Note:The difference in values of distStart and distEnd should not be too big, otherwise the fog will be unsmooth.

distDensity (distdensity) <float>

distDensity

Density of xog entity (seems bugged, only 0 and 1 works).

Todo: Confirm the developer note.

opacityOffsetTop (opacityoffsettop) <float>

opacityOffsetTop

opacityOffsetBottom (opacityoffsetbottom) <float>

opacityOffsetBottom

Contrast of xog.

noiseMultiplier (noisemultiplier) <float>

Multiplier of xog.

Enable Height Blend (enablevol_height) <choices>

Enable/Disable this heightbased xog.

Determines top color and blending is disabled or enabled.

• 0: Disabled
• 1: Enabled

Examples

Enable Height Blend - No. colorTop - 255 0 0 255, colorBottom - 0 255 0 255. Enable Height Blend - Yes. colorTop - 255 0 0 255, colorBottom - 0 255 0 255.

Flags

BaseTrigger

Everything (not including physics debris) : [64] Clients (Survivors, Special Infected, Tanks ) : [1] Only clients in vehicles : [32] Only clients *not* in vehicles : [512] Disallow Bots (removed since ) : [4096] NPCs (Common Infected, Witches ) : [2] Only player ally NPCs : [16] Only NPCs in vehicles (respects player ally flag) : [2048] Physics Objects (not including physics debris) : [8] Physics debris (include also physics debris) : [1024] Pushables (Passes entities with classname func_pushable) : [4]  Deprecated. Equivalent to using Everything + filter_activator_class that filters func_pushable.

Inputs

TurnOn <void>

Turn xog on.

TurnOff <void>

Turn xog off.

BaseTrigger

Toggle Toggles this trigger between enabled and disabled states. Enable Enable trigger Disable Disable trigger TouchTest  (in all games since ) Triggers either the OnTouching or OnNotTouching outputs for whether anything is touching this entity. Bug:Sleeping prop_physics will never fire "OnTouching". Also applies to entities using prop_physics as base.  (tested in: ) StartTouch  (in all games since ) !FGD Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities. EndTouch  (in all games since ) !FGD Behave as if !caller had just exited the trigger volume. DisableAndEndTouch  (only in ) Disables this trigger and calls EndTouch on all currently-touching entities.

Outputs

BaseTrigger

OnStartTouch !activator = entity that caused this output !caller = this entity Fired when a valid entity starts touching this trigger. OnStartTouchAll !activator = entity that caused this output !caller = this entity Fired when a valid entity starts touching this trigger, and no other entities are touching it. If there are any other entities touching the trigger when a new one begins to touch, only OnStartTouch will fire. OnEndTouch !activator = entity that caused this output !caller = this entity Fired when a valid entity stops touching this trigger. Note:Will also fire for entities touching it when trigger is disabled via Disable input Warning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid. Warning:OnEndTouch can fire before OnStartTouch under certain circumstances[How?] where both are fired on the same tick and each have the same delay. Fix:Add a slight delay to OnEndTouch. OnEndTouchAll !activator = entity that caused this output !caller = this entity Fired when all valid entities stop touching this trigger. OnTouching  (in all games since ) !activator = !caller = this entity Fired if something is currently touching this trigger when TouchTest is fired. OnNotTouching  (in all games since ) !activator = !caller = this entity Fired if nothing is currently touching this trigger when TouchTest is fired.
