phys_hinge

Code classes:

• CPhysHinge
• CPhysConstraint
• CLogicalEntity
• CServerOnlyEntity
• CBaseEntity (all ents)

phys_hinge is a point entity present in all Source games. It forces one or two entities to rotate only on a single axis, but otherwise move as normal.

Flags

• 8: Change mass to keep stable attachment to world^[Clarify]

Keyvalues

Friction (hingefriction) <float>

How stiff the hinge is. Note: No amount of friction will stop the gravity gun from bending the hinge, but hinges with extremely high friction will bounce back to their original angle.

Hinge Axis (hingeaxis) <vecline>

The "other" end of the rotation axis.

Load Scale (SystemLoadScale) <float>

"Scale of the load connected to this hinge (1=just the objects directly connected)"^[Clarify]

Travel sound (forward) (slidesoundfwd) <sound> (only available in Episodic)

Sound to make when the hinge is rotating clockwise.

Travel sound (backward) (slidesoundback) <sound> (only available in Episodic)

Sound to make when the hinge is rotating counter-clockwise.

Minimum Sound Velocity (minSoundThreshold) <float> (only available in Episodic)

When rotating below this speed, don't play any sounds.

Full Sound Velocity (maxSoundThreshold) <float> (only available in Episodic)

When rotating above this speed, play sounds at full volume.

Reversal sound (small) (reversalsoundSmall) <sound> (only available in Episodic)

Sound to play when the hinge makes a reversal at a speed between the small and medium Reversal sound thresholds.

Reversal sound (medium) (reversalsoundMedium) <sound> (only available in Episodic)

Sound to play when the hinge makes a reversal at a speed between the medium and large Reversal sound thresholds.

Reversal sound (large) (reversalsoundLarge) <sound> (only available in Episodic)

Sound to play when the hinge makes a reversal at a speed above the Reversal sound threshold (large).

Reversal sound threshold (small) (reversalsoundthresholdSmall) <float> (only available in Episodic)

If the hinge makes a reversal with at least this much angular acceleration/deceleration, the Reversal sound (small) will play.

Reversal sound threshold (medium) (reversalsoundthresholdMedium) <float> (only available in Episodic)

If the hinge makes a reversal with at least this much angular acceleration/deceleration, the Reversal sound (medium) will play.

Reversal sound threshold (large) (reversalsoundthresholdLarge) <float> (only available in Episodic)

If the hinge makes a reversal with at least this much angular acceleration/deceleration, the Reversal sound (large) will play.

Inputs

SetAngularVelocity <float>

Makes the hinge begin rotating this many degrees per second.

SetHingeFriction (Not in FGD) <float>

Sets Friction.
