A result Asset built using a tri-dimensional curve made out of control points. Once created this path can be used to force Object to follow it; you can use them to in examples, create predefined camera paths, control NPC patrol areas etc...

Static Variables

Name	Description
`asset`	Parent Asset where the Path structure is maintained.

Functions

Name	Description
`GetLength`	Retrieve the total length of the Path based on a certain transformation.
Declaration float GetLength( const mat4 m ) Parameters `m`: A 4x4 transformation matrix that will be used to transform the control points of the path. Return Value The total distance covered when following the Path made of control points.
`SetPointAt`	Update a certain point on the Path curve.
Declaration bool SetPointAt( unsigned int index, const vec3 location ) Parameters `index`: Index of the point to update. `location`: The new location of the point. Return Value `true` if the control point have been updated sucessfully; else return `false`.
`GetPointAt`	Retrieve the location of an existing control point along the Path using its index as key.
Declaration vec3 GetPointAt( unsigned int index ) Parameters `index`: Index of the control point to retrieve the location for. Return Value If the `index` is invalid a zeroed vector will be returned; else the active location of the control point pointed by the index.
`CalculateLocalBounds`	Manually force the LocalBounds update of the active Path.
Declaration void CalculateLocalBounds( void ) Note Only necessary if some control points have been manually updated.
