Energy Socket (Entity)
Energy_socket is an Half-Life 2 entity found only in 2002's sawyer\submarine map in the WC Mappack.
In the only WC Mappack appearance,
energy_socket is hidden in style lights visgroup.
That entity appears four times (like a prefab), each time (for %number% from 1 to 4) there is following structure:
lightentity named "light_%number%" which is initially dark by using 'a' (minimal brightness) custom pattern (Initially dark spawnflag not used)
prop_dynamicnamed "light_%number%_fixture" - light source model, also used as sound source point
ambient_genericnamed "light_%number%_sound" - "electrical" (TODO: explain) sound source (ambient/objects/func_train/electric1.wav - present in leak), off by-default
energy_socketentity without properties, without inputs and with following outputs:
|Attached1||light_%number%||SetPattern||mnlnmmnlm||Makes a "pulsating power source" effect|
|AttachedNone||light_%number%||SetPattern||a||Turns light off|
It seems to be some earlier implementation of plug-and-socket puzzle, but no plugs found on that map.
In leaked source code
In 2003 and 2007 source code no
energy_socket mentions found.
