|
|
"targetname" Name
|
|
"target" Name of an entity in the map that light will point at.
|
|
"lightcolor" Color of the projected texture light + intensity (unused?)
|
|
"style" Light appearance style of the projected texture.
|
|
"texturename" Name of the texture to be cast as a light.
|
|
"farz" Distance to which this projected light will be cast.
|
|
"nearz" Clipping distance for near objects that won't get lit.
|
|
"pattern" Sets a custom pattern. 'style' overrides this.
|
|
|
|
Inputs:
|
|
"TurnOff" Turns the entity off.
|
|
"TurnOn" Turns the entity on.
|
|
"Toggle" Toggles the entity to an on/off state.
|
|
"SpotlightTexture" Sets the projected texture to a specified path.
|
|
"LightColor" Sets the color of the light in RGB255 form.
|
|
"SetLightStyle" Sets the light appearance integer.
|
|
"SetNearZ" Sets clipping distance for near objects that won't get lit.
|
|
"SetFarZ" Sets distance to which this projected light will be cast.
|
|
"SetPattern" Sets the style pattern of the light to a custom one.
|
|
|
|
Textured light projected. This is the type of lighting that's used for
|
|
flashlights, lamp spotlights and so on.
|
|
|
|
Trivia:
|
|
This entity was introduced in Half-Life 2: Episode One (2006).
