Interact with line

[NV4RE]

Hello,

I want to create resize-able room by dragging

Currently to interact with line, I'm create transparent React over line to make interact but it did not work well when line is curved

How should I do to get interact with line ?

 

drawWalls() {
        this.lineStyle(30, 0, 1);
        this.beginFill(defaultVal(this._options.backgroundColor, 0xe74c3c), 1);
        this.moveTo(this._options.points[0].x, this._options.points[0].y);
        let totalPoints = this._options.points.length;
        for (let i = 1; i < totalPoints; i++) {
            this.addChild(new Wall([this._options.points[i - 1], this._options.points[i]])); // my interact overlay
            this.lineTo(this._options.points[i].x, this._options.points[i].y);
        }
        this.endFill();
    }
