It is an entity that marks a point in a rope. This entity can be shown as keyframe_rope
or move_rope
, but the two are completely identical in code. The purpose of double name is to make placing ropes in hammer simpler. First entity in a rope chain should be move_rope with Next Keyframe being set to some keyframe_rope. That way the rope will be properly visualized in hammer and shift-dragging keyframe_rope will properly connect to the previous one.
Tip:Holding ⇧ Shift while moving a properly named keyframe_rope will create a new keyframe_rope entity that is automatically connected to the previous keyframe. Also, deleting a keyframe_rope within a connected series will update the other entities to re-connect to the next entity in the series.
Note:In and , this entity will automatically have festive lights applied to its model during the winter holiday season. These lights are purely cosmetic and do not emit light. This can be disabled in via tf_gamerules.
Warning:This entity cannot be parented in multiplayer titles as it is a preserved entity. In , this can be fixed with VScript by assigning the following script to any rope entity that needs to move.

Note:This is a preserved entity in .
- On a new round, its properties including its position will intentionally not reset. You can use logic_auto to emulate resetting it.
- Killing it removes it forever, as it is not respawned on a new round.
- It cannot be spawned with a point_template.
- Parenting this with non preserved entities may have undesirable effects.
Keyvalues
Targetname:
- Name
(targetname)
<string> - The targetname that other entities refer to this entity by.
- Next KeyFrame
(NextKey)
<targetname> - Name of the next keyframe along this keyframe path.
- Slack
(Slack)
<integer> - How much extra length the rope has (by default it has the length between its two endpoints in the editor).
- Type
(Type)
<choices> - Rope type.
- 0 : Rope
- 1 : Semi-rigid
- 2 : Rigid
- Subdivision
(Subdiv)
<integer> - Number of subdivisions between each rope segment. Maximum value is 8. Higher values make smoother ropes, but are slower to render.
- Barbed
(Barbed)
<boolean> - Test effect that makes the rope look sharper and more barbed.
- Width (1-64)
(Width)
<string> - Width of the rope. Decimal values lower than 1 may also be used.
- Texture Scale
(TextureScale)
<string> - This changes the texture resolution. The default resolution is 4 pixels per inch. Larger values stretch the texture and smaller values scrunch it up.
- Collide with world
(Collide)
<boolean> - If set, the rope collides with world. Ropes never collide with anything else.
- Start Dangling
(Dangling)
<boolean> - If set, the rope starts out detached from its target endpoint.
- Breakable
(Breakable)
<boolean> - If set, the rope can be detached from either endpoint when shot. Note:If collide with world is set, the rope will not appear to break if the endpoint touches world geometry. This includes touching vertices and edges of brushes as well as being placed inside them.
- Rope Material
(RopeMaterial)
<material> - The material to use when rendering the rope. Note:Source will not render ropes using the cable/chain.vmt material.
- UseWind
(UseWind)
<boolean> (in all games since ) - When set to yes, the rope sways with the settings specified in the env_wind entity. Replaces "Disable Wind" in games post Alien Swarm.
- Disable Wind
(NoWind)
<boolean> (only in ) - If set, the rope will no longer act as though it's being affected by wind.
- Position Interpolator
(PositionInterpolator)
<choices> - Curve Type. Currently only type 2 (Rope) is fully supported.
- 0 : Linear
- 1 : Catmull-Rom Spline
- 2 : Rope
- Note:This is only in the FGD for move_rope, but is functional on both entities.
- Note:This keyvalue is shown, but is locked in all games with TeamSpen's Hammer Addons installed
Flags
- [
1
] : Auto Resize
Allows the rope to "stretch" as the entity moves.
Inputs
SetScrollSpeed
<float>- Set the speed at which the texture scrolls.
SetForce
<string>- Apply a force instantaneously to the rope. The parameter should be a vector containing the force to be applied (X Y Z).
Break
- Break the rope, if it's marked to do so.
