Light spot

Entity Description

An cone-shaped, invisible light source. Can be turned on and off through inputs, though switchable lights may cause lightmap errors. This is a static spotlight that can be pointed at another entity.

NOTE: When using this entity, it is often necessary to turn the brightness value up significantly for the effects of the light to be visible. Values of 3000-4000 are sometimes necessary for light sources like streetlights.

Keyvalues

• Template:Kv targetname

<string> The targetname value for a spotlight will point the light at the entity named. If no targetname is available, the entity will point with it's angles paramater.

• ((kv angles))

<degrees> This will control the direction the light points at, if no targetname is specified.

• _light

<color255 + integer> The color and brightness of the light. RGB colors need to be between 0 and 255. Brightness can be higher.

• _inner_cone

<integer> This is the inner focus of the light, or the edge of the brightest part of the light. It will fade from here out to the

• _cone

<integer>

• style

<choices> A preset pattern of diverse flicker effects.

Literal Value	Description
0	Normal
1	Flicker A
2	Slow, strong pulse
3	Candle A
4	Fast strobe
5	Gentle pulse
6	Flicker B
7	Candle B
8	Candle C
9	Slow strobe
10	Fluorescent flicker
11	Slow pulse, noblack

• pattern

<string> A string of characters defining a custom pattern, a being most dark and z being most bright.

• _constant_attn

<float> Brightens or dims the intensity of the light near its entity. A high constant will dim the light.

• _linear_attn

<float> Brightens or dims the intensity of the light emitted. A high linear will dim the light.

• _quadratic_attn

<float> Increase to make a light bright but not travel far.

• _distance

<integer> Stops the light emitted from reaching beyond this distance. Useful in cutting down compiling time by not making lights extend infinitely.

Flags

• 1 : Initially Off

Inputs

Turns the light off.

• Toggle

Toggles the light on or off.

• SetPattern

Sets the light's custom appearance to the input's parameters.
