# phys_hinge
A physically simulated hinge that restricts the rotation of its attached entities to a given axis. Use the helper to define the axis of rotation.
### Keyvalues
+ Name (`targetname`)
> The name that other entities refer to this entity by.
⤶
+ Tags (`tags`)
> A list of general purpose tags for this entity, for interactions with other entities such as triggers.⤶
⤶
+ Friction (`friction`)
> Resistance/friction in the constraint.
⤶
+ Min Rotation Limit (`min_rotation`)
> Minimum rotation limit around hinge axis.
⤶
+ Max Rotation Limit (`max_rotation`)
> Maximum rotation limit around hinge axis.⤶
⤶
+ Initial rotation (`initial_rotation`)
> Initial rotation of the hinge (values -1 to 1 where -1 mean open at minimum limit and 1 means open at maximum limit)
⤶
+ Hinge Axis (`hingeaxis`)⤶
⤶
+ Motor Frequency (`motorfrequency`)
> Range 0 - 30 (only used when driving the relative angle through the angle input)
⤶
+ Motor damping ratio (`motordampingratio`)⤶
> Range 0 - 1 (only used when driving the relative angle through the angle input)
