# along_with

Puts children along the given path. If there's only one child, it will put the child for each point.

## Parameters

• `points` : The points along the path.
• `angles` : Rotate before translate each child. If not given, rotate children automatically according to `points` and `method`.
• `twist` : If given, each child will be twisted before applying each element of `points` and `angles`.
• `scale` : If given, each child will be scaled before applying each element of `points` and `angles`. It accepts a single value, `[sx, sy]` or `[sx, sy, sz]`.
• `method` : Which method does `along_with` take to guess how to rotate children if `angles` is not specified? It accepts two value, `"AXIS_ANGLE"` (default) and `"EULER_ANGLE"`. See `path_extrude` for more information. Since: 1.3.
