Entity Description

An entity which dynamically morphs terrain by pulling vertices along a normal. (Collision hull is not updated!)

Place this entity the desired distance from a terrain surface and set Angles (

Todo: Non-FGD keyvalue? It isn't in the FGD, so please clearify.

) to the normal along which you want to pull the vertices of the surface.

Keyvalues

Name (targetname) <string>[ Edit ]

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

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.

• startradius

<integer> Radius of the effect when morphing begins. Only this value is used if the effect is flagged to occur instantly.

• goalradius

<integer> Radius of the effect at the end of morphing. The radius of this effect will change from Start Radius to Goal Radius over the duration of this effect. This value is ignored if the effect is flagged to occur instantly.

• duration

<integer> The morph will take place over this period of time (seconds). Ignored if the Instant flag is set.

• fraction

<integer> Displacement Fraction - If set to 1, the terrain surface will be pulled exactly to this entity's position. If set to 0.5, the surface will be pulled exactly half way to this entity's position. If set to 2, the surface will be pulled to an imaginary point twice as far away as this entity. (Any fraction value greater than 1.0 will result in clipping. The surface cannot be pulled beyond this entity's position and any vertices attemping will clip to this entity's position. You may use this feature to create mesas.)

Flags

• 1 : Instant

If set, the morph will take place instantly instead of over time.

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.

• BeginMorph

Begin morphing terrain.
