env_global_light.cpp

env_global_light is a point entity available in Alien Swarm and Mapbase. It casts a shadow map that follows the player. Nearly identical to sunlight_shadow_control.

The main difference from an env_projectedtexture is that this projects orthographically (like sunlight) instead of in a radial fashion (like a lightbulb).

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

See also:  Generic Keyvalues, Inputs and Outputs available to all entities

Light Color (color) <color255>

RGBA color of the sunlight.

Color Transition Time (colortransitiontime) <float>

This is the number of seconds it takes to get from 0 to 255.^[Clarify]

Distance (distance) <float>

Height above the player where the projection originates from.

FOV (fov) <float>

This is the field of view that the sunlight casts in. Use lower values to simulate a more distant sun and sharper shadows.

NearZ Distance (nearz) <float>

Distance from the player where the near Z plane is. Anything closer to the projection origin

North Offset (northoffset) <float>

"This offsets the from the player position where the sun is attached."^[Clarify]

Texture Name (texturename) <material>

The light texture which this entity projects.

Enable Shadows (enableshadows) <boolean>

Enables shadows. If shadows are disabled, light may appear to go through objects. Disabling shadows may be ideal for lower-detail environments due to being less expensive.

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

Inputs

LightColor <color255>

Set the light color.

SetAngles <string>

Set the sun direction.

SetDistance <float>

Set the distance of the sun.

SetFOV <float>

Set the field of view the sun casts.

SetNearZDistance <float>

Set the near z distance.

SetNorthOffset <float>

Sets the north offset.

SetTexture <string>

Set the texture cookie of the sunlight.

EnableShadows <boolean>

Set whether shadow maps are enabled

EnableDisable:

Enable / Disable

Enable/disable this entity from performing its task. It might also disappear from view.
