light_spot is a point entity available in all GoldSrc games. A cone-shaped, invisible light source. Can be turned on and off through targets, though switchable lights may cause lightmap errors. This is a static spotlight that can be pointed at another entity.

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

Note:Use an info_null entity to have your light_spot point to a certain spot.

Key values

Targetname:

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Light:

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.

Custom Appearance (pattern) <string>

A string of english letters, like a sequence of piano keys, that define a pattern of brightness. a is 0%, m is 100%, and z is 200%. Requires light to have a targetname.

Inner (bright) angle <integer>

The angles of the inner spotlight beam.

Outer (fading) angle <integer>

The angles of the outer spotlight beam.

Is Sky <integer>

Whether or not this light should be used as sunlight cast from sky brushes.

Unlike light_environment, this does not have any special effect on MDL lighting, and does not have a per-PVS limit.

• 0 : No
• 1 : Yes

Target <target_destination>

The name of an entity in the map that the spotlight will point at. This will override the spotlight's angles.

Pitch Yaw Roll (Y Z X) (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.

Pitch <angle>

Overrides the pitch value in Angles, even if left at 0, so it needs to be specified. Contrary to Angles, the rotation of this pitch is measured counter-clockwise from the horizontal, so that 90 is straight up, while -90 is straight down. (It's simply the negative of a normal pitch value.)

ZHLT light source:

ZHLT Fade <float>

ZHLT Falloff <integer>

• 0 : Default
• 1 : Inverse Linear
• 2 : Inverse Square

Texlight (VHLT+) (_tex) <texture>

HLCSG will rename this entity to light_surface, using the specified texture as the emissive texture.

Spawnflags

• 1 : Initially dark
