Compound path problem

[juanproton]

IDK why i cant get this work. I assume im doing something wrong, but maybe this is not supported by the library.

this is what im trying to get>

that is in illustrator

this is my code

    let rrr = this.r / 20
    let result = rect.exclude(circle)
    result.strokeColor = 0

    for(let i = 1;i<5;i+=0.5){
       let pp = paperOffset.offset(result,-i*rrr)
    }

and this is what i get>

any ideas?

In the offset field, it seems that complex paths are not easy to handle, and no teacher is maintaining this project.
