How to use three-pathfinding - 5 common examples

const { Pathfinding } = require('three-pathfinding');

const pathfinder = new Pathfinding();
const ZONE = 'level';

/**
 * nav
 *
 * Pathfinding system, using PatrolJS.
 */
module.exports = AFRAME.registerSystem('nav', {
  init: function () {
    this.navMesh = null;
    this.agents = new Set();
  },

    this.el.object3D.updateMatrixWorld();
    const geometry = new THREE.Geometry().fromBufferGeometry(mesh.geometry);
    geometry.applyMatrix(mesh.matrixWorld);
    this.pathfinder.setZoneData(zone, Pathfinding.createZone(geometry));
  }
});

    this.navMesh = new THREE.Mesh(geometry);
    pathfinder.setZoneData(ZONE, Pathfinding.createZone(geometry));
    Array.from(this.agents).forEach((agent) => agent.updateNavLocation());
  },

    Array.from(this.agents).forEach(function (agent) {

    });
  },
