interpolate
fun interpolateAlongPath(endPosition: Position, pathType: PathType, amount: Double, result: Position): Position
Compute a position along a path between two positions. The amount indicates the fraction of the path at which to compute a position. This value is typically between 0 and 1, where 0 indicates the begin position (this position) and 1 indicates the end position.
Return
the result argument set to the computed position
Parameters
end
the path's end position
path
PathType indicating type of path to assume
amount
the fraction of the path at which to compute a position
result
a pre-allocated Position in which to return the computed result
