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.

Bug:Removing this entity without removing crane can cause crashes.  [todo tested in?]

Risk of Confusion:This is not a typical phys_ entity, it uses a model

Keyvalues

Name (targetname) <string>

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.

Force Limit to Break (lbs) (forcelimit) <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*inches) (torquelimit) <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 (massScale) <float>

A scale multiplier for the object's mass.

Override parameters (overridescript) <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 (maxobjects) <integer>

The maximum number of physics objects that can be stuck to the magnet at once. 0 = no limit.

Flags

• 1 : Start Asleep
• 2 : Motion Disabled
• 4 : Suck On Touch
• 8 : Allow Attached Rotation
• 16 : Coast jeep pickup hack - Used on d2_coast_01 to prevent objects from interfering with the crane as it picks up the buggy. It is hardcoded for use with prop_vehicle_jeep only.

Note:Another entity can be used by changing the entity's classname to prop_vehicle_jeep using AddOutput. However, if the game is saved/reloaded or the round restarts in multiplayer, the entity will no longer function and will cause crashes.

Inputs

TurnOn

Turn the magnet on.

TurnOff

Turn the magnet off. This will detach anything current stuck to the magnet.

Toggle

Toggle the magnet on or off.

Outputs

OnAttach

Fired when an entity is grabbed by the magnet.

OnDetach

Fired when an entity is released by the magnet.
