logic_playerproxy is a point entity available in Half-Life 2 series, Portal series, Alien Swarm, Counter-Strike: Global Offensive, and Black Mesa.

It is used to relay inputs/outputs to the player and back to the world.

Note:Outputs will only fire on the first instance of this entity in the map.

Note:This entity is primarily intended for use in singleplayer, but all of the games it is present in can be played in multiplayer as well, even if they were not designed with it in mind. Thus, the entity exhibits varying behavior in multiplayer depending on the game:

• In Orange Box games and Portal 2, outputs will fire correctly, with the player that triggered the output as the !activator.
• In Orange Box games, inputs will affect the most recently connected player.
• In Portal 2, inputs will do nothing and produce the console message Can't use logic player proxy in multiplayer! (which is slightly erroneous, as outputs still work as mentioned previously).
• In Alien Swarm and CS:GO (which are multiplayer only), the entity does not function at all.
