- public class v_LinearAttraction_v
- extends NodeVec2
Generates a vector towards a goal location
that varies with distance from the goal. The attraction is
increased linearly at greater distances. Based on
Arkin's formulation.
Arkin's original formulation is described in
"Motor Schema Based Mobile Robot
Navigation," International Journal of Robotics Research,
vol. 8, no 4, pp 92-112.
The source code in this module is based on "first principles"
(e.g. published papers) and is not derived from any previously
existing software.
For detailed information on how to configure behaviors, see the
Clay page.

v_LinearAttraction_v
public v_LinearAttraction_v(double czr,
double dzr,
NodeVec2 im1)
- Instantiate a v_LinearAttraction_v schema.
- Parameters:
czr
- double, controlled zone radius.dzr
- double, dead zone radius.im1
- double, the node that generates an
egocentric vector to the goal.
Value
public Vec2 Value(long timestamp)
- Return a Vec2 representing the direction to go towards the
goal. Magnitude varies with distance.
- Overrides:
- Value in class NodeVec2
- Parameters:
timestamp
- long, only get new information if timestamp > than last call
or timestamp == -1.- Returns:
- the movement vector.
