env_ambient_light
...
env_ambient_light
is a point entity available in all Source games since Alien Swarm. This entity adds a constant color value to dark areas of the world without affecting brighter areas. It can be faded in and/or take effect only within a certain radius (meaning brightness will increase as the viewer draws closer to the entity, not that there will be a spatial effect).
Note:The ambient term is completely flat, making this entity a poor replacement for static light.
Bug:This entity works by setting the
mat_ambient_light_
cvars to the values specified in the entity. This doesn't cause any problems in Alien Swarm, but in Portal 2 and later, the cvars will not be reset when changing maps! This makes the entity only suitable for standalone mods, as using it in a singular map will cause the effects to carry over into every following map that the user plays until another map turns it back off or the game is restarted.- Workaround: To prevent your map from being affected by ambient light from a previous map, you can place a
env_ambient_light
entity in your map set to 0 0 0 to clear any previous ambient light values.
Keyvalues
- Color (R G B) (Color)
(???)
<color255> - Ambient light color.
SpatialEntity:
- Lookup Falloff Start Distance (minfalloff)
(???)
<float> - Within this range to the entity, the effect will be at full strength. If this is larger than the End Distance, the effect will apply to the entire map.
- Lookup Falloff End Distance (maxfalloff)
(???)
<float> - Maximum distance from the entity that the effect is applied. At this distance, the effect is barely apparent but will strengthen as the viewer approaches the Start Distance.
- Maximum Weight (maxweight)
(???)
<float> - This is the maximum weight for this lookup.[Clarify]
- Lookup Fade In Duration (fadeInDuration)
(???)
<float> - When the entity becomes
Enable
d, how long the effect takes to fade in.
- Lookup Fade out Duration (fadeOutDuration)
(???)
<float> - When the entity becomes
Disable
d, how long the effect takes to fade out.
EnableDisable:
- Start Disabled
(StartDisabled)
<boolean> - Stay dormant until activated (with the
Enable
input).
Base:
- Parent
(parentname)
<targetname> - Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (
parentname [targetname],[attachment]
)Tip:Entities transition to the next map with their parentsTip:phys_constraint
can be used as a workaround if parenting fails.
- Origin (X Y Z)
(origin)
<coordinates> - The position of this entity's center in the world. Rotating entities typically rotate around their origin.Note:Hammer does not move the entities accordingly only in the editor.
- Pitch Yaw Roll (X Y Z)
(angles)
<angle> - This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.Note:This works on brush entities, although Hammer doesn't show the new angles.
- Classname
(classname)
<string> !FGD - Determines the characteristics of the entity before it spawns. Tip:Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!
- Spawnflags
(spawnflags)
<flags> !FGD - Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.
- Effects
(effects)
<flags> !FGD - Combination of effect flags to use.
- Entity Scripts
(vscripts)
<скриптлист VScript> (in all games since ) (also in ) - Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions. Scripts executed on the worldspawn entity will be placed in root scope.
- Think function
(thinkfunction)
<string> (in all games since ) (also in ) - Name of the function within this entity's script that'll be called automatically every 100 milliseconds, or a user-defined interval if the function returns a number. Avoid expensive operations in this function, as it may cause performance problems.
- Lag Compensation
(LagCompensate)
<boolean> (in all games since ) !FGD - Set to Yes to lag compensate this entity. Should be used very sparingly!
- Is Automatic-Aim Target
(is_autoaim_target)
<boolean> (in all games since ) !FGD - If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.
Inputs
SetColor
<color255>- Sets the color.
SpatialEntity:
SetFadeInDuration
<float>- Sets the Lookup Fade In Duration.
SetFadeOutDuration
<float>- Sets the Lookup Fade out Duration.
EnableDisable:
Enable
Disable
- Enable/disable this entity from performing its task. It might also disappear from view.
Base:
AddContext
<string>- Adds to the entity's list of response contexts. See Context.
AddOutput
<string>- Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:
// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"
// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:ClearParent::0.0:-1"
|
ClearContext
- Removes all contexts from this entity's list.
ClearParent
- Removes this entity from the the movement hierarchy, leaving it free to move independently.
FireUser1
toFireUser4
- Fires the respective
OnUser
outputs; see User Inputs and Outputs.
Kill
- Removes this entity and any entities parented to it from the world.
KillHierarchy
- Functions the same as
Kill
, although this entity and any entities parented to it are killed on the same frame, being marginally faster thanKill
input.
RemoveContext
<string>- Remove a context from this entity's list. The name should match the key of an existing context.
SetParent
<string>- Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment
<string>- Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.
SetParentAttachmentMaintainOffset
<string>- As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
DispatchResponse
<string> !FGD- Dispatches a response to the entity. See Response and Concept.
DispatchEffect
<string> (removed since ) !FGD- Dispatches a special effect from the entity's origin; See also List of Client Effects. Replaced by the particle system since .
RunScriptFile
<скрипт> (in all games since ) (also in )- Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
RunScriptCode
<string> (in all games since ) (also in )- Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console. Bug:In Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.Fix:Remove the string argument manually with a text editor.
CallScriptFunction
<string> (in all games since ) (also in ) !FGD- Calls a VScript function defined in the scope of the receiving entity.
TerminateScriptScope
(only in ) !FGD- Destroys the script scope of the receving entity.
SetLocalOrigin
<coordinates> (in all games since ) !FGD- Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.
Outputs
Base:
OnUser1
toOnUser4
- These outputs each fire in response to the firing of the like-numbered
FireUser1
toFireUser4
Input; see User Inputs and Outputs.
