point_viewcontrolis a point entity available in all Source games. It is a camera entity that controls the player's view. While it's active, the player will see out of the camera.
Note:This entity has many problems. See the discussion page for full descriptions and fixes.
Bug: The camera doesn't follow its path correctly. It will not follow paths at all if it doesn't have an
Entity to Look Atset.
Bug: The camera ignores the
New Train Speedkeyvalue and
Teleport to THIS path_cornerspawnflag on path_tracks.
Bug: The camera fails to function when parented, logic_measure_movement can be used as a workaround.
Bug: If the camera is killed while active, or the player suicides, the camera will be stuck permanently on the player's screen. The only fix afterwards is for the player to reconnect to the server.
- Entity to Look At
- Name of the entity that the camera should point at and track while active.
- Target Attachment Name
- If set, the camera will focus on the specified attachment on the 'Entity to Look At'.
- Hold Time
- The amount of time the camera should control the player's view for, after which it deactivates itself. If the camera should stay active until told to deactive, set the 'Infinite Hold Time' spawnflag.
- Path Corner
- The first path corner in a track that the camera should move along once it's activated. If not specified, the camera won't move.
- Interpolate Position To Player
- Gradually interpolate player's position to here on start.
- Initial Speed
- The starting speed that the camera moves at, if it's on a path track.
- Acceleration units/sec^2
- The speed at which the camera accelerates to path corner's desired speeds.
- Stop Deceleration units/sec^2
- The speed at which the camera decelerates to path corner's desired speeds.
- The FOV when using this camera.
- FOV rate
- How fast we change to the new FOV.
- Tracking Speed of the camera
- The speed that the camera tries to follow its look target.
- Entity Scripts
- 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
- 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.
- Pitch Yaw Roll (Y Z X)
- This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
1] : Start At Player
- Start the camera at the player's position. Bug: Breaks the camera movement if the player was still moving when the camera activated.
2] : Follow Player
- This is the same as if you set the lookat target to !player. Bug: Causes camera issues in multiplayer.
4] : Freeze Player
- Stop recognizing input from the player.
8] : Infinite Hold Time
- Ignore the hold time, and stay activated until explicitly disabled.
16] : Snap to goal angles
32] : Make Player non-solid
64] : Interruptable by Player
- If the player presses +Use, disable.
128] : Set FOV !FGD
128] : All Players
- Controls the view of all players.
- Enable the
point_viewcontrol, and start controlling the player's view.
- Disable the
point_viewcontrol, and stop controlling the player's view.
- Set a new target for the camera to point at.
- Set a new attachment on the target for the camera to point at.
- Return the camera view to the player's eyes.
- Teleport the player to the current position of the camera.
- Set the speed that the camera will try to track it's target.
- Have the camera start following a new path.
- Removes this entity from the world.
- Removes this entity and its children from the world. Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than
- Adds a keyvalue/output to 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 depending on the entity. Can also be invoked by firing an output that does not specify an input.
- Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
- 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: 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.
- Execute a VScript function in the scope of the receiving entity.
- Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.
- Set this entity's angles.
- Fired when the
point_viewcontroldeactivates, due to the
Disableinput being received, the
Entity to Look Atbeing destroyed, or the
- These outputs each fire in response to the firing of the like-numbered
FireUser4Input; see User Inputs and Outputs.
- This output fires when the entity is killed and removed from the game.
