/*QUAKED func_monitor (0 .5 .8) ?
|
|
A monitor that renders the view of a linked point_camera entity.
|
|
|
|
-------- KEYS --------
|
|
"targetname" : Name
|
|
"target" : Camera it's linked to.
|
|
|
|
-------- INPUTS --------
|
|
"Enable" : Turns the monitor on
|
|
"Disable" : Turns the monitor on.
|
|
"Toggle" : Toggles the state of the monitor between on and off.
|
|
|
|
-------- TRIVIA --------
|
|
This entity was introduced in Half-Life 2 (2004).
