gravitationalFieldY method

num gravitationalFieldY(
  1. num x,
  2. num y
)

This returns the gravitational field in the Y direction acting on a vertex at the given point. By default there is no gravitational field at any location.

Used to define an external gravitational field at a point independent of the vertex masses. A vertex L is acted upon by a force in the Y direction of proportional to gravitationalFieldY(L.center.x, L.center.y) * gravitationalMass(L). Please read the Introduction page on Extensions for how to override methods and how to call this base method. @expose @param {number} x @param {number} y @return {number} the default implementation returns zero.

Implementation

_i2.num gravitationalFieldY(
  _i2.num x,
  _i2.num y,
) =>
    _i4.callMethod(
      this,
      'gravitationalFieldY',
      [
        x,
        y,
      ],
    );
