env_global_light

env_global_light is an e0 available in Alien Swarm. 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).

In code, it is represented by theCGlobalLightclass, defined in theenv_global_light.cppfile.

Dedicated Console Variables

{{varcom|cl_globallight_freeze|0|01|Freezes the env_global_light in place so that it won't follow the player.^[confirm]

Cvar/Command	Parameters or default value	Descriptor	Effect
cl_globallight_xoffset	-800	Hammer units	Offset from the player that the light originates from, along the X axis.
cl_globallight_yoffset	1600	Hammer units	Offset from the player that the light originates from, along the Y axis.

Keyvalues

Light Color (color) ([todo internal name (i)]) <color255>

RGBA color of the sunlight.

{{KV|Color Transition Time (colortransitiontime)|float|This is the number of seconds it takes to get from 0 to 255.^[Clarify]

Distance (distance) ([todo internal name (i)]) <float>

Height above the player where the projection originates from.

FOV (fov) ([todo internal name (i)]) <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) ([todo internal name (i)]) <float>

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

{{KV|North Offset (northoffset)|float|"This offsets the from the player position where the sun is attached."^[Clarify]

Texture Name (texturename) ([todo internal name (i)]) <material>

The light texture which this entity projects.

Enable Shadows (enableshadows) ([todo internal name (i)]) <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 <color255RedirectInput/color32>

Set the light color.

SetAngles <stringRedirectInput/string>

Set the sun direction.

SetDistance <floatRedirectInput/float>

Set the distance of the sun.

SetFOV <floatRedirectInput/float>

Set the field of view the sun casts.

SetNearZDistance <floatRedirectInput/float>

Set the near z distance.

Set whether shadow maps are enabled

EnableDisable:

Enable / Disable

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