- Not to be confused with GameUI.
game_ui is a point entity available in all Source games. It redirects important player key presses to a series of outputs, and can be used to make the player control vehicles built in a map. It can be activated with I/O, or by the player looking at it.
- How close to the entity the player's crosshair must be for it to take control. When the player leaves the active zone, (s)he regains control.
- 1.0 = straight ahead
- 0.0 = +/- 90 degrees
- -1.0 = all directions
- Entity Scripts
<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
<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.
- Freeze Player
- Hide Weapon
- +Use Deactivates
- Jump Deactivates
- The entity will only test FieldOfView if it is active. Warning:Deactivating an already-inactive game_ui crashes the game! This appears to be fixed in Source Engine 2009, though.
- Removes this entity and any entities parented to it from the world.
- Functions the same as
Kill, although entities with a large number of children are killed marginally faster.
- Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.
<output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
- Fire the
OnUseroutputs; see User Inputs and Outputs.
- Same as a player invoking +use; may not do anything. Can also be invoked by creating an output that does not specify an input.
This input is not included in Valve's FGDs.
<script>(New with Left 4 Dead 2)
- Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
<string>(New with Left 4 Dead 2)
- Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console. Bug: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.
<string>(New with Left 4 Dead 2) !FGD
- Execute a VScript function in the scope of the receiving entity. Note:This input is missing from some games FGD files.
<origin>(New with Alien Swarm) !FGD
- Set this entity's origin in the map. Note:This input is missing from some games FGD files.
<angles>(New with Alien Swarm) !FGD
- Set this entity's angles in the map. Note:This input is missing from some games FGD files.
The player is always the !activator.
- Fired when the entity starts or stops controlling the player's input.
UnpressedMoveLeft(New with Source 2007)
- Fired on +moveleft/-moveleft
UnpressedMoveRight(New with Source 2007)
- Fired on +moveright/-moveright
UnpressedForward(New with Source 2007)
- Fired on +forward/-forward
UnpressedBack(New with Source 2007)
- Fired on +back/-back
UnpressedAttack(New with Source 2007)
- Fired on +attack/-attack
UnpressedAttack2(New with Source 2007)
- Fired on +attack2/-attack2
- Fired whenever the X/Y axis of the player's input changes. Only useful for analogue gamepad input.
- -1.0 = +moveleft / +back at 100% speed
- 0 = no movement in this axis
- +1.0 = +moveright / +forward at 100% speed
- An output that fires whenever the state of the player's "attack" key changes. Only useful for analogue gamepad input.
- 1.0 = bumper is 100% depressed
- 0 = bumper is at rest
- These Outputs each fire in response to the firing of the like-numbered
FireUser4Input; see User Inputs and Outputs.
OnKilled(New with Left 4 Dead)
- This Output fires when the entity is killed and removed from the game.
