Phys magnet.png
phys_magnet is a point entity available in all Source games. It acts like a magnet, attaching metallic physics objects to itself when they touch it.

Warning: If a prop model is not specified for this entity, the map will crash with a memory could not be 'read' error.

Keyvalues

Force Limit to Break (lbs) <float>
The amount of force necessary to break a stuck object off the magnet. A way of calculating this is to set it to the mass of an object that would break this constraint if it were resting on the magnet.
Torque Limit to Break (lbs * distance) <float>
The amount of torque necessary to break a stuck object off the magnet. A way of calculating this is to multiply any reference mass by the resting distance (from the center of mass of the object) needed to break the constraint.
Mass Scale <float>
A scale multiplier for the object's mass.
Override parameters <string>
A list of physics key/value pairs that are usually in a physics prop .qc file. Format is 'key,value,key,value,etc'.
Maximum Attached Objects <integer>
The maximum number of physics objects that can be stuck to the magnet at once. 0 = no limit.

Targetname:

Name (targetname) <string>
The targetname that other entities refer to this entity by.
Entity Scripts (vscripts) <scriptlist> (in all games since <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 (thinkfunction) <string> (in all games since <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.

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.

Angles:

Pitch Yaw Roll (Y Z X) (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.

Studiomodel:

World Model (model) <string>
The model this entity should appear as. 128-character limit.
Skin (skin) <integer>
Some models have multiple skins. This value selects from the index, starting with 0.
Tip:Hammer's model browser automatically updates this value if you use it to view different skins.
Model Scale (modelscale) <float> (Only in Source 2013)
A multiplier for the size of the model.

Shadow:

Disable Shadows (disableshadows) <boolean>
Prevents the entity from creating cheap render-to-texture shadows, or lightmap shadows if the entity is a prop_static. Does not affect shadow mapping.
Disable ShadowDepth (disableshadowdepth) <boolean> (New with Portal 2)
Used to disable rendering into shadow depth (for projected textures) for this entity.
Projected Texture Cache (shadowdepthnocache) <choices> (New with Portal 2)
Used to hint projected texture system whether it is sufficient to cache shadow volume of this entity or to force render it every frame instead.
  • 0 : Default
  • 1 : No cache - render every frame
  • 2 : Cache it - render only once
Disable flashlight (disableflashlight) <boolean> (New with Portal 2)
Used to disable projected texture lighting and shadows on this entity.

Reflection:

Render in Fast Reflections (drawinfastreflection) <boolean> (New with Portal 2)
If enabled, this entity will render in fast water reflections (i.e. when a water material specifies $reflectonlymarkedentities) and in the world impostor pass.

Flags

  • 1 : Start Asleep
  • 2 : Motion Disabled
  • 4 : Suck On Touch
  • 8 : Allow Attached Rotation
  • 16 : Coast jeep pickup hack

Inputs

TurnOn
Turn the magnet on.
TurnOff
The the magnet off. This will detach anything current stuck to the magnet.

Targetname:

Kill
Removes this entity from the world.
KillHierarchy
Removes this entity and its children from the world.
Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than Kill.
AddOutput <string>
Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
KV Format: <key> <value>
I/O 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 depending on the entity. Can also be invoked by firing an output that does not specify an input.
RunScriptFile <script> (in all games since <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> (in all games since <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> (in all games since <Left 4 Dead 2>) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin <coordinates> (in all games since <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> (in all games since <Alien Swarm>) !FGD
Set this entity's angles.

Parentname:

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

Studiomodel:

Skin <integer>
Changes the model's skin to the specified number.
SetBodyGroup <integer>
Set the model's body group.
AlternativeSorting <boolean>
Uses an alternative method for telling which objects are in front of others. Use if this object draws incorrectly when seen through transparent things.
SetModelScale <string> (only in <Source><Source>)
Sets the model scale. Takes two values separated by a space. The first is the target model scale. The second value is the number of seconds the change in scale will be spread over. If there is no second value, the model will scale instantly. Warning: Negative or extremely high values can cause crashes!

Shadow:

DisableShadow
Turn dynamic shadows off for this entity.
EnableShadow
Turn dynamic shadows on for this entity.
DisableReceivingFlashlight  (New with Portal 2)
This object will not receive light or shadows from projected textures.
EnableReceivingFlashlight  (New with Portal 2)
This object may receive light or shadows from projected textures.

Reflection:

DisableDrawInFastReflection  (New with Portal 2)
Turns off rendering of this entity in reflections when using $reflectonlymarkedentities in water material.
EnableDrawInFastReflection  (New with Portal 2)
Turn on rendering of this entity in reflections when using $reflectonlymarkedentities in water material.

ToggleDraw:

DisableDraw  (New with Portal 2)
Add the EF_NODRAW flag to this entity. Some entities manage this on their own so be aware you can override that value.
EnableDraw  (New with Portal 2)
Remove the EF_NODRAW flag from this entity. Some entities manage this on their own so be aware you can override that value.

Outputs

OnAttach
Fired when an entity is grabbed by the magnet.
OnDetach
Fired when an entity is released by the magnet.

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 <Left 4 Dead><Left 4 Dead 2>)
This output fires when the entity is killed and removed from the game.

Studiomodel:

OnIgnite
Fired when this object catches fire.
