/*QUAKED prop_physics_multiplayer (0 0 0.8) (-16 -16 -16) (16 16 16) PRPPHYS_ASLEEP
Physics prop that is optimised for netplay.
It either pushes the player away, or gets pushed away by the player.
The simulation can take place on either client or server.
-------- KEYS --------
"targetname" : Name
"physicsmode" : Which type of push/simulation model to use. See notes.
-------- NOTES --------
'physicsmode' can be one of three things:
1 - push player away
2 - get pushed (server-side)
3 - get pushed (client-side)
-------- TRIVIA --------
This entity was introduced in Half-Life 2 (2004).
