 <p>Two strategies can be used to make such complex forms. The generic <code>Bodies.polygon()</code> method can create any regular polygon (pentagon, hexagon, and so on). Additionally, <code>Bodies.trapezoid()</code> makes a quadrilateral with at least one pair of parallel sides:</p>

 <p>A more general-purpose option is <code>Bodies.fromVertices()</code>. It builds a shape from an array of vectors, treating them as a series of connected vertices. I’ll encapsulate this logic in a <code>CustomShape</code> class.</p>

 <p>Technically, the only required options are <code>bodyA</code> and <code>bodyB</code>, the two bodies connected by the constraint. If you don’t specify any additional options, Matter.js will choose defaults for the other properties. For example, it will use <code>(0, 0)</code> for each relative anchor point (the body’s center), set the <code>length</code> to the current distance between the bodies, and assign a default <code>stiffness</code> of <code>0.7</code>. Two other notable options I didn’t include are <code>damping</code> and <code>angularStiffness</code>. The <code>damping</code> option affects the constraint’s resistance to motion, with higher values causing the constraint to lose energy more quickly. The <code>angularStiffness</code> option controls the rigidity of the constraint’s angular motion, with higher values resulting in less angular flexibility between the bodies.</p>
 <p>Once the options are configured, the constraint can be created. As usual, this assumes another alias—<code>Constraint</code> is equal to <code>Matter.Constraint</code>:</p>
