public class v_SwirlLeft_va
extends NodeVec2
Generate a vector that aways swirls to the left of detected hazards. The embedded perceptual schema provides a list of hazards This is useful for "always turn left" type behaviors. The "swirl" behavior was originally developed by Andy Henshaw and Tom Collins.

For detailed information on how to configure behaviors, see the Clay page.

                       double s,
                       NodeVec2Array im1)
Instantiate a v_SwirlLeft_va schema.

Parameters:
soe - double, the sphere of influence beyond which the hazards are not considered.
s - double, the safety zone, inside of which a maximum repulsion from the object is generated.
im1 - double, the embedded perceptual schema that generates a list of items to avoid.

Methods

 o Value
 public Vec2 Value(long timestamp)
Return a Vec2 representing the direction to go.

Parameters:
timestamp - long, only get new information if timestamp > than last call or timestamp == -1.
Returns:
the movement vector.
Overrides:
Value in class NodeVec2
