LTSpline Class
Animate along a set of points that need to be in the format: controlPoint, point1, point2.... pointLast, endControlPoint
Constructor
LTSpline
-
pts
Parameters:
-
ptsVector3 ArrayA 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

transform:Transform -
ratio:float
Place an object along a certain point on the path (facing the direction perpendicular to the path)
Parameters:
-
transform:TransformTransformthe transform of the object you wish to place along the path
-
ratio:floatFloatratio of the point along the path you wish to receive (0-1)
Example:
ltPath.place( transform, 0.6f );

transform:Transform -
ratio:float -
rotation:Vector3
Place an object along a certain point on the path, with it facing a certain direction perpendicular to the path
Parameters:
-
transform:TransformTransformthe transform of the object you wish to place along the path
-
ratio:floatFloatratio of the point along the path you wish to receive (0-1)

point
-
ratio:float
Retrieve a point along a path
Parameters:
-
ratio:floatFloatratio of the point along the path you wish to receive (0-1)
Returns:
Vector3 position of the point along the path
Example:
transform.position = ltSpline.point( 0.6f );
ratioAtPoint
-
point:Vector3
Retrieve a point along a path
Parameters:
-
point:Vector3Vector3given a current location it makes the best approximiation of where it is along the path ratio-wise (0-1)
Returns:
float of ratio along the path
Example:
ratioIter = ltSpline.ratioAtPoint( transform.position );
