This entity is not in the FGD by default.
See below for instructions on making it available.

Entity description

Rocket tripwire. An unfinished entity from the development stage of Portal 2.

It fires rockets in a straight line to the direction it is looking when the player, an NPC or a physical prop is visible. It uses the model of Portal's npc_rocket_turret (which is broken in Portal 2), but behaves much different and doesn't use any of its animations.

	input  EnableTripwire(void) : "Enable tripwire."
	input  DisableTripwire(void) : "Disable tripwire."
	input  ForceFire(void) : "Trip the tripwire."

Parentname:

Parent (parentname) <targetname>

Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma.

Pitch Yaw Roll (Y Z X) (angles) <QAngle>

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.

Inputs

Parentname:

SetParent <stringRedirectInput/string>

Move with this entity. See Entity Hierarchy (parenting).

SetParentAttachment <stringRedirectInput/string>

Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.

SetParentAttachmentMaintainOffset <stringRedirectInput/string>

As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.

ClearParent

Removes this entity from the the movement hierarchy, leaving it free to move independently.

Outputs

OnTripped

Triggered when the tripwire is tripped.

OnRocketExplode

Triggered when the tripwire rocket is exploded.
