Examples of org.jbox2d.dynamics.Body.createFixture()

org.jbox2d.dynamics.Body.createFixture()
Creates a fixture and attach it to this body. Use this function if you need to set some fixture parameters, like friction. Otherwise you can create the fixture directly from a shape. If the density is non-zero, this function automatically updates the mass of the body. Contacts are not created until the next time step. @param def the fixture definition. @warning This function is locked during callbacks.

      fd.density = 0.0f;
      fd.friction = 0.6f;


      shape.set(new Vec2(-20.0f, 0.0f), new Vec2(20.0f, 0.0f));
      ground.createFixture(fd);


      float hs[] = {0.25f, 1.0f, 4.0f, 0.0f, 0.0f, -1.0f, -2.0f, -2.0f, -1.25f, 0.0f};
