Usage of ngCyclic module of darlingjs for simulate cyclic bacgrounds

cyclic-world.js

var w = darlingjs.w('theCyclicWorld', ['ngCyclic']);
 
//add systems for implement cyclic behaviour
world.$add('ng2DCyclicLayer');
world.$add('ngMarkIfOutsideOfTheViewPortVertical2D');
world.$add('ngMarkIfOutsideOfTheViewPortHorizontal2D');
world.$add('ngMarkIfInsideOfTheViewPortVertical2D');
world.$add('ngMarkIfInsideOfTheViewPortHorizontal2D');
 
//add entity
world.$e('theEntity', {
    ng2D: {
        x: 10.0,
        y: 10.0
    },
    
    ngCyclic: {
        patternWidth: 1000,
        patternHeight: 1000
    }
});
 
//start simulation
world.$start();
