logic_playerproxy is a point entity available in the following Source engine games: Half-Life 2, Portal, Alien Swarm, Portal 2, Counter-Strike: Global Offensive. It is used to relay inputs/outputs to the player and back to the world.
- Entity Scripts (vscripts)
<scriptlist>(New with Left 4 Dead 2)
- Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.
- Script think function (thinkfunction)
<string>(New with Left 4 Dead 2)
- Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call. Note:Try to avoid expensive operations in this function, as it may cause performance problems.
- Requests the current player's health from the proxy. This will fire the PlayerHealth output with the value.
- Puts the player's flashlight in slow-power-drain mode (for Episodic darkness)
- Puts the player's flashlight to default power drain
- Sets the player's health to this value.
- Request the ammo state of the player. It will fire PlayerHasAmmo or PlayerHasNoAmmo outputs.

SuppressCrosshair(New with Portal 2010 ARG Update) !FGD
- Hides the crosshair. Note:Unlike the command
crosshair 0, the crosshair is enabled again when a new game is started or a save made before firing the input is loaded.Note:Seems to be a backported Portal 2 input that was later scrapped from Portal 2. Does not appear to be used in Portal, and does not exist in Portal 2.

<string>(New with Left 4 Dead 2)

Bug: In , the code is executed in the script scope of the entity that fires the output, not the one receiving the input.Warning: Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.
