Color correction volume

Template:Base brush A color correction lookup table is faded in or out when a player enters or leaves its volume. Fade time is configurable.

Warning:This entity will not work correctly in any multiplayer games except Left 4 Dead.

Todo: Is this still accurate? Should be tested per-game cause the note is very old.

Workaround:Use trigger_multiple brushes to output commands that disable an active color_correction entity and enable a separate color_correction entity in its place; upon touch.

Note:If a color_correction entity has a value of -1 in both lookup falloff start and end distance, and is active as soon as you spawn, then enable that entity's "Master" flag. All other inactive color_correction entities must be set to "StartDisabled" as seen in their keyvalues for this to work correctly.

In code, it is represented by theCColorCorrectionVolumeclass, defined in thecolorcorrectionvolume.cppfile.

Keyvalues

Lookup Fade Duration (fadeDuration) ([todo internal name (i)]) <float>

How fast the effect fades in or out when the viewer enters or exits.

Maximum Weight (maxweight) ([todo internal name (i)]) <float>

This is the maximum weight for this lookup.^[Clarify]

Lookup Table Filename (filename) ([todo internal name (i)]) <string>

Pathfile from the mod folder to the .raw to reference. For info on making a file, see color correction. Example path for a file in the hl2 materials folder: materials/colorcorrection.raw

BaseTrigger

Filter Name (filtername) <filter> A filter entity to test potential activators against. Start Disabled (StartDisabled) <boolean> Stay dormant until activated (with theEnableinput).

Inputs

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.
