It moves linearly along a given distance, in a given direction. Unlike a func_door
, it can be positioned anywhere along its axis of movement, making moving things much simpler in most cases while also using less memory. For moving water, use func_water_analog
instead.
Note:The
SetPosition
input and Start Position keyvalue do not perform any bounds checking, so values less than 0 and greater than 1 can be used. Negative values will move in the opposite direction to the movement direction, and values greater than 1 will move it in multiples of the set Move Distance. Moving past the opened/closed position does not trigger the OnFullyOpen
and OnFullyClosed
outputs.Bug:There are bugs that may arise when parenting this entity to any of these:
func_movelinear
, momentary_door
, func_lookdoor
, func_water_analog
. A func_door
can be used as a workaround.- Code Fix: See here for a code fix.
- Confirm:Might be fixed in Portal 2? Parented movelinears are used extensively for this game's piston platforms.
Bug:In , parenting a
move_rope
or keyframe_rope
will cause the entities to disappear. Clarification required if the rope entities are deleted or are simply not rendered.AltNames: This entity is also tied to
momentary_door
. This was the original classname in GoldSource.

Flags
FuncMoveLinear:
- 8: Not Solid
Bug:Physics objects cannot be constrained to this entity when this flag is enabled.

Base:
- Brush Model
(model)
<string> !FGD - Which bmodel to display.
- Collisions
(solid)
<choices> - Method of collision for this entity.
Values:
- 0: None
- 1: BSP (QPhysics) !FGD Bug:In , if an entity using QPhysics collisions is hit by Gel, the game will crash!
- 2: Bounding Box
- 3: Oriented Bounding Box (Use for runtime spawned brush entities meant to be rotated) !FGD
- 4: Oriented Bounding Box but constrained to Yaw only !FGD
- 5: Custom/Test (Usually no collision with anything) !FGD
- 6: VPhysics
- Parent
(parentname)
<targetname> - Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (
parentname [targetname],[attachment]
)Tip:Entities transition to the next map with their parentsTip:phys_constraint
can be used as a workaround if parenting fails.
- Origin (X Y Z)
(origin)
<coordinates> - The position of this entity's center in the world. Rotating entities typically rotate around their origin.Note:Hammer does not move the entities accordingly only in the editor.
- Pitch Yaw Roll (X Y Z)
(angles)
<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.Note:This works on brush entities, although Hammer doesn't show the new angles.
- Classname
(classname)
<string> !FGD - Determines the characteristics of the entity before it spawns. Tip:Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!

(spawnflags)
<flags> !FGD - Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.
- Effects
(effects)
<flags> !FGD - Combination of effect flags to use.
- Entity Scripts
(vscripts)
<scriptlist> (in all games since ) (also in ) - 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. Scripts executed on the worldspawn entity will be placed in root scope.
- Think function
(thinkfunction)
<string> (in all games since ) (also in ) - Name of the function within this entity's script that'll be called automatically every 100 milliseconds, or a user-defined interval if the function returns a number. Avoid expensive operations in this function, as it may cause performance problems.
- Lag Compensation
(LagCompensate)
<boolean> (in all games since ) !FGD - Set to Yes to lag compensate this entity. Should be used very sparingly!
- Is Automatic-Aim Target
(is_autoaim_target)
<boolean> (in all games since ) !FGD - If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.
Inputs

- Move the brush to the starting position.
SetPosition
<float>- Move the brush to a specific position, where 0 is the starting position and 1 is the starting position + (move direction * move distance).
SetSpeed
<float>- Set the speed and update immediately.
Visible Brush:
Alpha
<integer 0–255>- Sets the entity's transparency to a number from 0 (invisible) to 255 (fully visible). Requires the entity to have its Render Mode (rendermode) set to a number other than

EnableDraw
(in all games since )- Removes
EF_NODRAW
from the entity.
DisableDraw
(in all games since )- Applies
EF_NODRAW
to the entity. Note that this is different fromrendermode 10
.
EnableReceivingFlashlight
(in all games since )- Makes it so that the entity is lit by
env_projectedtexture
s.
DisableReceivingFlashlight
(in all games since )- Prevents the entity from being lit by
env_projectedtexture
s. The shadow made by the texture will still cast.
Reflection:
DisableDrawInFastReflection
(in all games since )- Turns off rendering of this entity in reflections when using
$reflectonlymarkedentities
in water material.
EnableDrawInFastReflection
(in all games since )- Turn on rendering of this entity in reflections when using
$reflectonlymarkedentities
in water material.
Shadow:
DisableShadow
- Turn dynamic shadows off for this entity. Identical to applying
EF_NOSHADOW
.

Base:
AddContext
<string>- Adds to the entity's list of response contexts. See Context.
AddOutput
<string>- Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:
// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"
// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:ClearParent::0.0:-1"
|
ClearContext
- Removes all contexts from this entity's list.
ClearParent
- Removes this entity from the the movement hierarchy, leaving it free to move independently.
FireUser1
toFireUser4
- Fires the respective
OnUser
outputs; see User Inputs and Outputs.
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 thanKill
input.
RemoveContext
<string>- Remove a context from this entity's list. The name should match the key of an existing context.
SetParent
<string>- Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment
<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
<string>- As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
DispatchResponse

RunScriptCode
<string> (in all games since ) (also in )- 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 Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.Fix:Remove the string argument manually with a text editor.
CallScriptFunction
<string> (in all games since ) (also in ) !FGD- Calls a VScript function defined in the scope of the receiving entity.
TerminateScriptScope
(only in ) !FGD- Destroys the script scope of the receving entity.

OnFullyOpen
- Fired when the brush reaches the end position (starting position + (move direction * move distance)).
OnFullyClosed
- Fired when the brush reaches the starting position.
Base:
OnUser1
toOnUser4
- These outputs each fire in response to the firing of the like-numbered
FireUser1
toFireUser4
Input; see User Inputs and Outputs. OnKilled
(only in )- This output fires when the entity is killed and removed from the game.
