Our straps should follow the neck opening, which isn’t that hard to do. We just need to keep the control points of our curves at similar proportions. Which means, halfway between the start of the curve, and the corner of our rectangle.
For this, you’ll be using a new method:
Point.shiftFractionTowards(). We’ve already used
Point.shift()and there’s also
Point.shiftOutwards(). As always, the API docs have all the details.
points.edgeLeft = new Point(points.topLeft.x, points.left.y); points.edgeRight = new Point(points.topRight.x, points.right.y); points.edgeTop = new Point(0, points.topLeft.y); points.edgeLeftCp = points.edgeLeft.shiftFractionTowards(points.topLeft, 0.5); points.edgeRightCp = points.edgeLeftCp.flipX(); points.edgeTopLeftCp = points.edgeTop.shiftFractionTowards( points.topLeft, 0.5 ); points.edgeTopRightCp = points.edgeTopLeftCp.flipX();
Now, adapt our
rect path so it’s no longer a rectangle:
paths.rect = new Path() .move(points.edgeTop) .curve(points.edgeTopLeftCp, points.edgeLeftCp, points.edgeLeft) .line(points.bottomLeft) .line(points.bottomRight) .line(points.edgeRight) .curve(points.edgeRightCp, points.edgeTopRightCp, points.edgeTop) .close();
All of a sudden, things are starting to look like a bib:
