Point push

From Valve Developer Community
Jump to: navigation, search
point_push can be used to re-create the Pneumatic Diversity Vent from Portal 2.

This is a point entity available in all Source games (except <Counter-Strike: Global Offensive>). It is a push sphere that will push any physics props or entity that has a movement type set (e.g. NPCs) away from its origin. It will not push parented objects -- so if you want to keep some entities rooted, you can parent them temporarily to something static.

Keyvalues

Magnitude <float>
How strongly to push away from the center.
Tip:Using a negative value will draw items toward the center, creating a "gravity well" effect.
Radius <float>
Radius to affect items in.
Inner radius <float>
If not zero, the LOS is calculated from a point intersecting this sphere.
influencecone <integer> (New with Portal 2) !FGD
The fov of the cone a physics object must be in to be affected by.
Confirm:Does it exist in games before Portal 2?

EnableDisable:

Start Disabled (StartDisabled) <boolean>
Stay dormant until activated (probably with the Enable input).

Targetname:

Name <string>
The targetname that other entities refer to this entity by.
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.

Angles:

Pitch Yaw Roll (Y Z X) <angle>
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.

Flags

  • 1 : Test LOS before pushing
  • 2 : Use angles for push direction
  • 4 : No falloff (constant push at any distance)
  • 8 : Push players
  • 16 : Push physics

Inputs

EnableDisable:

Enable
Disable
Enable/disable this entity from performing its task. It might also disappear from view.

Targetname:

Kill
Removes this entity and any entities parented to it from the world.
KillHierarchy
Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster than Kill.
AddOutput  <string>
Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.
Format: <key> <value>
Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
FireUser1 to FireUser4
Fire the OnUser outputs; see User Inputs and Outputs.
Use  !FGD
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.
RunScriptFile  <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.
RunScriptCode  <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 <Left 4 Dead 2>, 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.
CallScriptFunction  <string> (New with Left 4 Dead 2) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin  <coordinates> (New with Alien Swarm) !FGD
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.
SetLocalAngles  <angles> (New with Alien Swarm) !FGD
Set this entity's angles.

Outputs

Targetname:

OnUser1 to OnUser4
These Outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.
OnKilled  (Only in the Left 4 Dead series)
This Output fires when the entity is killed and removed from the game.
