<p><h2>function CreateSlideConstraint( actorA, frameInB_matrix, useLinearReferenceFrameA) </h2></p>

<p>
|
|
A type of constraint that restricts the motion between two actors (or between an actor and the world) in such a way that they can slide along a specific axis and rotate around the same axis, while limiting or allowing movement along other axes. This constraint is similar to a prismatic joint with added rotational freedom, making it useful for simulating objects like pistons, sliding doors, or rail systems.
