javascript - Detect object completely inside another object -

good day everyone,

i wondering if there way detect if fabric object inside object?

i looking @ object.intersectswithobject(object2) in documentation unfortunately, object inside object2, function doesn't give true anymore false.

has else had problem? not know @ how this. have searched function in fabric.js. can help?

    intersectswithobject: function(other) {   // extracts coords   function getcoords(ocoords) {     return {       tl: new fabric.point(ocoords.tl.x, ocoords.tl.y),       tr: new fabric.point(ocoords.tr.x, ocoords.tr.y),       bl: new fabric.point(ocoords.bl.x, ocoords.bl.y),       br: new fabric.point(ocoords.br.x, ocoords.br.y)     };   }   var thiscoords = getcoords(this.ocoords),       othercoords = getcoords(other.ocoords),       intersection = fabric.intersection.intersectpolygonpolygon(         [thiscoords.tl, thiscoords.tr, thiscoords.br, thiscoords.bl],         [othercoords.tl, othercoords.tr, othercoords.br, othercoords.bl]       );    return intersection.status === 'intersection'; } 

thank sebastian

if want know if abject inside object should use iscontainedwithinobject:

iscontainedwithinobject(other) → {boolean}

§ checks if object contained within area of object

parameters:

name : other
type: object

description: object test

source: fabric.js, line 12300

returns: true if object contained within area of object

type: boolean

this source:

iscontainedwithinobject: function(other) {       var boundingrect = other.getboundingrect(),           point1 = new fabric.point(boundingrect.left, boundingrect.top),           point2 = new fabric.point(boundingrect.left + boundingrect.width, boundingrect.top + boundingrect.height);        return this.iscontainedwithinrect(point1, point2);     } 

it works using bounding box of object test.
