/*QUAKED light_dynamic (1 0 0) (-8 -8 -8) (8 8 8)
|
|
Dynamic light entity. Can be parented to things, it even has some inputs that
|
|
may be interesting.
|
|
|
|
-------- KEYS --------
|
|
"targetname" : Name
|
|
"target" : Name of an entity in the map that light will point at.
|
|
"_light" : Color of the spotlight in RGB255 format.
|
|
"brightness" : Intensity of the spotlight.
|
|
"_inner_cone" : Angles of the inner spotlight beam. 0 = omnidirectional.
|
|
"_cone" : Angles of the outer spotlight beam. 0 = omnidirectional.
|
|
"distance" : Distance that light is allowed to cast, in inches.
|
|
"spotlight_radius" : Radius of the resulting spotlight that's cast at a wall.
|
|
"style" : Select one of the hard-coded lightstyles.
|
|
"start_active" : Override for if the entity should start on or off.
|
|
"pattern" : Override the lightstyle pattern with a string.
|
|
|
|
-------- INPUTS --------
|
|
"TurnOn" : Turns the light on.
|
|
"TurnOff" : Turns the light off.
|
|
"Toggle" : Toggles the light from an on/off state.
|
|
"Color" : Sets the light color in RGB255 format.
|
|
"brightness" : Sets the light brightness.
|
|
"distance" : Sets the distance of which the light will travel/radius.
|
|
"_inner_cone" : Sets the length of the inner light cone.
|
|
"_cone" : Sets the length of the light cone.
|
|
"spotlight_radius" : Sets the radius of the projected spotlight.
|
|
"style" : Sets the light appearance in integer form.
|
|
"SetPattern" : Sets the light pattern in string form! a = dark, z = bright
|
|
|
|
-------- NOTES --------
|
|
The 'start_active' is a Nuclide specific one. There is no way in Source engine
|
|
games to tell the entity to start inactive as far as I can tell.
|
|
|
|
-------- TRIVIA --------
|
|
This entity was introduced in Half-Life 2 (2004).
