# OVERVIEW
|
|
Textured light projected. This is the type of lighting that's used for
|
|
flashlights, lamp spotlights and so on.
|
|
|
|
# KEYS
|
|
- "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. The "style" key 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.
|
|
|
|
# SPAWNFLAGS
