phys_torque is a point entity available in all Source games. It is an angular thruster. Use it to apply angular force to an entity.

Example:See steamapps/common/sourcesdk_content/hl2/mapsrc/sdk_phys_torque.vmf for example use (comes with Source SDK installation ^[confirm])

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.

Angular Acceleration (force) <string>

Axial acceleration acting on the object.

Rotation Axis (axis) <vector>

The point to the Origin of the entity whose line the rotation axis.

ForceController:

Attached Object (attach1) <targetname>

Object to apply the force to.

Time of Force (0=inf) (forcetime) <float>

Automatic shut-off after this time has passed. A value of 0 means to stay on forever or until deactivated.

Flags

ForceController:

Start On : [1]

Thrust is on by default (will turn off in forcetime)

Apply Force : [2]

Apply linear force (if off, torque only)

Apply Torque : [4]

Apply rotational force (torque - if off, linear only)

Orient Locally : [8]

Maintain local relationship with the attached object

Ignore Mass : [16]

Impulse is independent of object's mass (impulse is acceleration NOT force)

Inputs

ForceController:

Activate

Turn the force on

Deactivate

Turn the force off

Scale <float>

Set Force Scale
