title: Path.shiftAlong()
|
|
---
|
|
|
|
The `Path.shiftAlong()` method returns a point that lies at distance travelled
|
|
along the path.
|
|
|
|
## Signature
|
|
|
|
```js
|
|
Point path.shiftAlong(float distance, int stepsPerMm = 10)
|
|
```
|
|
|
|
The second parameter controls the precision by which the path will be _walked_.
|
|
By default, we'll divide it into 10 steps per mm.
|
|
|
|
If you don't need that precision, you can pass a lower number.
|
|
If you need more precision, you can pass a higher number.
|
|
For most cases, the default will be fine.
|
|
|
|
## Example
|
|
|
|
<Example caption="Example of the Path.shiftAlong() method">
