You can use an Angular Dashpot to constrain the relative orientation of two rigid bodies, or the absolute orientation of a rigid body in world space. When simulating, the dashpot exerts impulses on the bodies to which it is attached in an attempt to maintain the specified rotation between the objects. You can specify the dashpot’s strength and damping, and whether collisions between the system’s bodies are disabled.
An angular dashpot has two sets of axes as sub-objects. For two-bodied dashpots, these are specified as offset rotations from the dashpot’s bodies. For single-bodied dashpots, one sub-object is an offset rotation and the other is a world rotation. In a simulation, the dashpot tries to maintain a common rotation for these axes.
When set to true , the Parent Body will be used in the simulation.
Get/Set the strength value which governs the size of the impulse the dashpot will apply to each attached body, taking into account the difference in their relative offset rotations (Child Space and Parent Space). The strength value is mass dependent.
Get/Set the sampling value which affects how quickly the oscillation of the angular dashpot settles down. It governs the impulse applied to the connected bodies due to their relative angular velocities.
When set to true , collisions are disabled between the dashpot’s objects - during the simulation, they will be able to pass through each other. Defaults to false .
When set to true , the dashpot is not added to the simulation
When set to true , the relative transform between the child and parent constraint spaces is locked - if you move the child space in the viewport, the parent space will move with it, and vice versa.

Aligns the Constraint to the Parent Body.
Aligns the Constraint to the Child Body.
Aligns the Constraint to parent space.
Aligns the Constraint to child space.
Aligns the Constraint to both bodies.
Returns true if the Constraint is valid, false otherwise. A valid Constraint has the correct number of rigid bodies attached and is included in a valid constraint solver.
