Lasso selection of stickies and paths

Draw a path with thin lines

It is essential to separate layers that are updated frequently

if you let go

Highlighting selected items?

At any rate, this one looks easier.

×x hitTest from each point of the selected path

→The inside of the path is not selected.

Stickies are 4 corners, paths are hitTest from each point to the selected range path

The more objects there are, the heavier it is going to be.

Proposal to use path and path boolean operations

This is simple, but there are performance concerns.

I'd implement it without worrying about it for now, and if it's too slow, maybe narrow it down with a bounding box first!

It looks like they are already doing it internally!

This is just "hitTest at each point of the given Array({point: Point})

→ First, let's try to implement it with boolean operations.

Verify that it runs fast enough

100 sticky intersect runs 20msec on iPad.

The hit detection in the case of full inclusion instead of intersect does not work well with the planned boolean operation.

This is probably because while intersects are defined for Path and Shape

The implementation assumes that subtract is Path and Path

I guess the method that arg called internally thinking it was Path is dead because it doesn't exist.

cope

If the shape is fully contained, a hitTest at a point relative to the center of gravity of the shape will definitely hit the Path if the opponent is a Shape.

If subtract can be used when the other party is Path, then there is no problem.

The path must be filled, so clone and fill with opacity: 0.

The percussion between the sticky and the sticky works fine now.

It also moves to determine if it hits a pass or not.
