Declaration
- (instancetype)initWithPoints:(vectorParameters
pointsAn array of 2D points representing the vertices in the path. The order of points in this array determines the order in which an agent follows the path.
countThe number of elements in the
pointsarray.radiusThe radius of the path.
cyclicalYESif the path’s end point should connect to its start point; otherwiseNO.
Return Value
A new path object.
Discussion
The radius parameter defines the space occupied by the path—think of this space as the area created by sweeping a circle of the specified radius along the path from vertex to vertex. Agents with path-related goals will attempt to move to or stay within this area.
The cyclical parameter determines whether the path loops around on itself. If the path is cyclical, an agent with a follow-path goal will proceed around the path indefinitely. If the path is not cyclical, an agent following the path will stop at the last point in the path.
To use the newly created path to constrain an agent’s behavior, create a goal with the goal or goal method.
