# LTSpline Class

Defined in: `LeanTween.cs:2651`

Animate along a set of points that need to be in the format: controlPoint, point1, point2.... pointLast, endControlPoint

## Constructor

### `LTSpline`

(

- `pts`

)

Defined in `LeanTween.cs:2651`

#### Parameters:

- `pts` Vector3 Array

  A set of points that define the points the path will pass through (starting with starting control point, and ending with a control point)
  Note: The first and last item just define the angle of the end points, they are not actually used in the spline path itself. If you do not care about the angle you can jus set the first two items and last two items as the same value.

#### Example:

LTSpline ltSpline = new LTSpline( new Vector3[] { new Vector3(0f,0f,0f),new Vector3(0f,0f,0f), new Vector3(0f,0.5f,0f), new Vector3(1f,1f,0f), new Vector3(1f,1f,0f)} );
LeanTween.moveSpline(lt, ltSpline.vec3, 4.0f).setOrientToPath(true).setDelay(1f).setEase(LeanTweenType.easeInOutQuad); // animate
Vector3 pt = ltSpline.point( 0.6f ); // retrieve a point along the path

## Methods

### `place`

(

- `transform:Transform`
- `ratio:float`

)

Defined in `LeanTween.cs:2863`

Place an object along a certain point on the path (facing the direction perpendicular to the path)

#### Parameters:

- `transform:Transform` Transform

  the transform of the object you wish to place along the path

- `ratio:float` Float

  ratio of the point along the path you wish to receive (0-1)

#### Example:

ltPath.place( transform, 0.6f );

### `place`

(

- `transform:Transform`
- `ratio:float`
- `rotation:Vector3`

)

Defined in `LeanTween.cs:2876`

Place an object along a certain point on the path, with it facing a certain direction perpendicular to the path

#### Parameters:

- `transform:Transform` Transform

  the transform of the object you wish to place along the path

- `ratio:float` Float

  ratio of the point along the path you wish to receive (0-1)

- `rotation:Vector3` Vector3

  the direction in which to place the transform ex: Vector3.up

#### Example:

ltPath.place( transform, 0.6f, Vector3.left );

### `placeLocal`

(

- `transform:Transform`
- `ratio:float`

)

Defined in `LeanTween.cs:2895`

Place an object along a certain point on the path (facing the direction perpendicular to the path) - Local Space, not world-space

#### Parameters:

- `transform:Transform` Transform

  the transform of the object you wish to place along the path

- `ratio:float` Float

  ratio of the point along the path you wish to receive (0-1)

#### Example:

ltPath.placeLocal( transform, 0.6f );

### `placeLocal`

(

- `transform:Transform`
- `ratio:float`
- `rotation:Vector3`

)

Defined in `LeanTween.cs:2908`

Place an object along a certain point on the path, with it facing a certain direction perpendicular to the path - Local Space, not world-space

#### Parameters:

- `transform:Transform` Transform

  the transform of the object you wish to place along the path

- `ratio:float` Float

  ratio of the point along the path you wish to receive (0-1)

- `rotation:Vector3` Vector3

  the direction in which to place the transform ex: Vector3.up

#### Example:

ltPath.placeLocal( transform, 0.6f, Vector3.left );

### `point`

(

- `ratio:float`

)
Vector3

Defined in `LeanTween.cs:2828`

Retrieve a point along a path

#### Parameters:

- `ratio:float` Float

  ratio of the point along the path you wish to receive (0-1)

#### Returns:

Vector3:

Vector3 position of the point along the path

#### Example:

transform.position = ltSpline.point( 0.6f );

### `ratioAtPoint`

(

- `point:Vector3`

)
Float

Defined in `LeanTween.cs:2804`

Retrieve a point along a path

#### Parameters:

- `point:Vector3` Vector3

  given a current location it makes the best approximiation of where it is along the path ratio-wise (0-1)

#### Returns:

Float:

float of ratio along the path

#### Example:

ratioIter = ltSpline.ratioAtPoint( transform.position );

## Properties

### `distance distance of the spline (in unity units)`

Float

Defined in `LeanTween.cs:2667`
