title: utils.beamIntersectsY()
|
|
---
|
|
|
|
The `utils.beamIntersectsY()` function finds the intersection between an endless
|
|
line and a given Y-value. Returns a [Point](/reference/api/point) object for
|
|
the intersection, or `false` there is no intersection.
|
|
|
|
## Signature
|
|
|
|
```js
|
|
Point | false utils.beamIntersectsY(Point A, Point B, float Y)
|
|
```
|
|
|
|
## Example
|
|
|
|
<Example caption="A Utils.beamIntersectsY() example">
|
|
```js
|
|
({ Point, points, Path, paths, Snippet, snippets, utils, part }) => {
|
|
|
|
points.A = new Point(10, 10)
|
|
points.B = new Point(50, 40)
|
|
|
|
paths.AB = new Path().move(points.A).line(points.B)
|
|
|
|
snippets.x = new Snippet(
|
|
"notch",
|
|
utils.beamIntersectsY(points.A, points.B, 30)
|
|
)
