info_camera_link is a point entity available in all Source games. It can use point_cameras to render images for materials used by entities. To author the material, use the special identifier
_rt_Camera for the
$baseTexture (which is the only material that it will work with) in the .vmt then connect the 'target' field to the entity which uses that material, and the 'PointCamera' field to the
point_camera you want to have appear on that entity's material.
- For an example of use, refer to the Half-life 2 map
d3_breen_01, where the model
effects/portalrift.mdl(skinned with the
_rt_Camerabase texture material) is used to let the player see through the opening Combine portal.
- Entity Whose Material Uses _rt_camera
- The entity with the screen on it.
- Camera Name
- The name of a point_camera entity in the map that the material should be rendered from.
- 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.
- Set the camera to use. The parameter should be the name of a point_camera entity in the map.
- 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: 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.
<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.
- 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.
- func_monitor - An alternative entity devoted to displaying the contents of a point_camera.
