light

light is a point entity available in all GoldSrc games. It's an invisible static light source, which can optionally be toggled or flicker.

AltNames:light and light_spot are both tied to the same C++ class in game, and only differ in QRAD/HLRAD.

Key Values

Target (target) <targetname>: The targetname of an entity this entity will trigger when activated.; Note:If a light targets a entity, it becomes a spotlight, like light_spot (GoldSrc).

Name (targetname) <string>: The targetname that other entities refer to this entity by.

Light:

Color + Brightness (_light) <color255 + int>: The RGB color and brightness of the light. Colors must be between 0 and 255; brightness can be anything.; Note:Negative brightness will suck out the amount of lighting that the equivalent positive brightness would cast.

Appearance (lightstyle) (style) <choices>: Various lightstyle presets. Cannot be used on named lights.
