| Inheritance | AngularConstraint  Constraint |
Angular constraints are built from 3 points. The first and last are on the side of the constraints
The middle point (particleB) is the pivot point.
The angle in an angular constraint is measured between 0 - 360 and is never negative.
When all three points lie on the same line, the angle is 0 (or 360)
the angle increases as the segment between particleB and particleC rotates clockwise
Note that in their nature, angular constraints are not as stable as spring constraints. Always use springs over angular constraints where possible.
Angular constraints work well when spread out over a few particles. Generally, refrain from angular constrainting over the same object more than 3 different times
For more general constraint features like breakable constraints, see the Constraint class
