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.

v_SwirlLeft_va

public v_SwirlLeft_va(double soe,
                      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.

Return a Vec2 representing the direction to go.

Overrides:

Value in class NodeVec2

Parameters:

timestamp - long, only get new information if timestamp > than last call or timestamp == -1.

Returns:

the movement vector.
