public class CollisionAvoider

extends Movement

Two 'moves' that may collide and must be adjusted. Dance instructions often result in collisions of two people. These are resolved by rules such as 'ladies first', or 'person who started facing the active person crosses in front of person who started behind the active person'. To avoid the need for complex path adjustments and time adjustments in the dance specification, one can instead simply say who yields to whom and let the dance animation logic work out the details.

This class represents a pair of moves that may collide. The collision should be avoided by adjusting the moves so that one person goes ahead of the other.

Field Summary
